I played with this two weeks ago, it's very simple. The only problem is that all the tutorials just talk about saving the image locally. This is how I did it:

1) I set up a form so I can use a POST method.

2) When the user is done drawing, he can click the "Save" button.

3) When the button is clicked I take the image data and put it into a hidden field. After that I submit the form.

document.getElementById('my_hidden').value = canvas.toDataURL('image/png');
document.forms["form1"].submit();

4) When the form is submited I have this small php script:

<?php 
$upload_dir = somehow_get_upload_dir();  //implement this function yourself
$img = $_POST['my_hidden'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = $upload_dir."image_name.png";
$success = file_put_contents($file, $data);
header('Location: '.$_POST['return_url']);
?>

Your command should include the url parameter as stated in the script usage comments. The main function has 2 parameters, url and out (which is set to a default value) C:\python23\python "C:\PathToYourScript\SCRIPT.py" http://yoururl.com "C:\OptionalOutput\"

Pure JS

You can use fetch optionally with await-try-catch

let photo = document.getElementById("image-file").files[0];
let formData = new FormData();
     
formData.append("photo", photo);
fetch('/upload/image', {method: "POST", body: formData});

async function SavePhoto(inp) 
{
    let user = { name:'john', age:34 };
    let formData = new FormData();
    let photo = inp.files[0];      
         
    formData.append("photo", photo);
    formData.append("user", JSON.stringify(user)); 
    
    const ctrl = new AbortController()    // timeout
    setTimeout(() => ctrl.abort(), 5000);
    
    try {
       let r = await fetch('/upload/image', 
         {method: "POST", body: formData, signal: ctrl.signal}); 
       console.log('HTTP response code:',r.status); 
    } catch(e) {
       console.log('Huston we have problem...:', e);
    }
    
}

<input id="image-file" type="file" onchange="SavePhoto(this)" >

Before selecting the file open chrome console > network tab to see the request details.
<br><br>
<small>Because in this example we send request to https://stacksnippets.net/upload/image the response code will be 404 ofcourse...</small>

<br><br>
(in stack overflow snippets there is problem with error handling, however in <a href="https://jsfiddle.net/Lamik/b8ed5x3y/5/">jsfiddle version</a> for 404 errors 4xx/5xx are <a href="https://stackoverflow.com/a/33355142/860099">not throwing</a> at all but we can read response status which contains code)

Old school approach - xhr

let photo = document.getElementById("image-file").files[0];  // file from input
let req = new XMLHttpRequest();
let formData = new FormData();

formData.append("photo", photo);                                
req.open("POST", '/upload/image');
req.send(formData);

function SavePhoto(e) 
{
    let user = { name:'john', age:34 };
    let xhr = new XMLHttpRequest();
    let formData = new FormData();
    let photo = e.files[0];      
    
    formData.append("user", JSON.stringify(user));   
    formData.append("photo", photo);
    
    xhr.onreadystatechange = state => { console.log(xhr.status); } // err handling
    xhr.timeout = 5000;
    xhr.open("POST", '/upload/image'); 
    xhr.send(formData);
}

<input id="image-file" type="file" onchange="SavePhoto(this)" >

Choose file and open chrome console > network tab to see the request details.

(the stack overflow snippets, has some problem with error handling - the xhr.status is zero (instead of 404) which is similar to situation when we run script from file on <a href="https://stackoverflow.com/a/10173639/860099">local disc</a> - so I provide also js fiddle version which shows proper http error code <a href="https://jsfiddle.net/Lamik/k6jtq3uh/2/">here</a>)

SUMMARY

• In server side you can read original file name (and other info) which is automatically included to request by browser in filename formData parameter.
• You do NOT need to set request header Content-Type to multipart/form-data - this will be set automatically by browser.
• Instead of /upload/image you can use full address like http://.../upload/image.
• If you want to send many files in single request use multiple attribute: <input multiple type=... />, and attach all chosen files to formData in similar way (e.g. photo2=...files[2];... formData.append("photo2", photo2);)
• You can include additional data (json) to request e.g. let user = {name:'john', age:34} in this way: formData.append("user", JSON.stringify(user));
• You can set timeout: for fetch using AbortController, for old approach by xhr.timeout= milisec
• This solutions should work on all major browsers.

I know this is old, but, in running into a vendor that inconsistently uses 5 different date formats in their APIs (and test servers with a variety of PHP versions from the 5's through the latest 7's), I decided to write a universal converter that works with a myriad of PHP versions.

This converter will take virtually any input, including any standard datetime format (including with or without milliseconds) and any Epoch Time representation (including with or without milliseconds) and convert it to virtually any other format.

To call it:

$TheDateTimeIWant=convertAnyDateTome_toMyDateTime([thedateIhave],[theformatIwant]);

Sending null for the format will make the function return the datetime in Epoch/Unix Time. Otherwise, send any format string that date() supports, as well as with ".u" for milliseconds (I handle milliseconds as well, even though date() returns zeros).

Here's the code:

        <?php   
        function convertAnyDateTime_toMyDateTime($dttm,$dtFormat)
        {
            if (!isset($dttm))
            {
                return "";
            }
            $timepieces = array();
            if (is_numeric($dttm))
            {
                $rettime=$dttm;
            }
            else
            {
                $rettime=strtotime($dttm);
                if (strpos($dttm,".")>0 and strpos($dttm,"-",strpos($dttm,"."))>0)
                {
                    $rettime=$rettime.substr($dttm,strpos($dttm,"."),strpos($dttm,"-",strpos($dttm,"."))-strpos($dttm,"."));
                    $timepieces[1]="";
                }
                else if (strpos($dttm,".")>0 and strpos($dttm,"-",strpos($dttm,"."))==0)
                {               
                    preg_match('/([0-9]+)([^0-9]+)/',substr($dttm,strpos($dttm,"."))." ",$timepieces);
                    $rettime=$rettime.".".$timepieces[1];
                }
            }

            if (isset($dtFormat))
            {
                // RETURN as ANY date format sent
                if (strpos($dtFormat,".u")>0)       // Deal with milliseconds
                {
                    $rettime=date($dtFormat,$rettime);              
                    $rettime=substr($rettime,0,strripos($rettime,".")+1).$timepieces[1];                
                }
                else                                // NO milliseconds wanted
                {
                    $rettime=date($dtFormat,$rettime);
                }
            }
            else
            {
                // RETURN Epoch Time (do nothing, we already built Epoch Time)          
            }
            return $rettime;    
        }
    ?>

Here's some sample calls - you will note it also handles any time zone data (though as noted above, any non GMT time is returned in your time zone).

The only thing not in this version is the ability to select the time zone you want the returned datetime to be in. Originally, I wrote this to change any datetime to Epoch Time, so, I didn't need time zone support. It's trivial to add though.

Many of the above mentioned solutions might suite different people.
I would like to suggest a slightly modified code than most accepted solution by "MusiGenesis".

DateTime firstTime = DateTime.Parse( TextBox1.Text );
DateTime secondTime = DateTime.Parse( TextBox2.Text );
double milDiff = secondTime.Subtract(firstTime).TotalMilliseconds;

Considerations:
- earlierTime.Subtract(laterTime) you will get a negative value.
- use int milDiff = (int)DateTime.Now.Subtract(StartTime).TotalMilliseconds; if you need integer value instead of double
- Same code can be used to get difference between two Date values and you may get .TotalDays or .TotalHours insteaf of .TotalMilliseconds

I find std::getline() is often the simplest. The optional delimiter parameter means it's not just for reading "lines":

#include <sstream>
#include <iostream>
#include <vector>

using namespace std;

int main() {
    vector<string> strings;
    istringstream f("denmark;sweden;india;us");
    string s;    
    while (getline(f, s, ';')) {
        cout << s << endl;
        strings.push_back(s);
    }
}

You will need to import the other file as a module like this:

import Math

If you don't want to prefix your Calculate function with the module name then do this:

from Math import Calculate

If you want to import all members of a module then do this:

from Math import *

Edit: Here is a good chapter from Dive Into Python that goes a bit more in depth on this topic.

This is useful in contexts where the encoding is not told per HTTP header or other meta data, e.g. the local file system.

Imagine the following stylesheet:

[rel="external"]::after
{
    content: ' ?';
}

If a reader saves the file to a hard drive and you omit the @charset rule, most browsers will read it in the OS’ locale encoding, e.g. Windows-1252, and insert ↗ instead of an arrow.

Unfortunately, you cannot rely on this mechanism as the support is rather … rare. And remember that on the net an HTTP header will always override the @charset rule.

The correct rules to determine the character set of a stylesheet are in order of priority:

1. HTTP Charset header.
2. Byte Order Mark.
3. The first @charset rule.
4. UTF-8.

The last rule is the weakest, it will fail in some browsers.
The charset attribute in <link rel='stylesheet' charset='utf-8'> is obsolete in HTML 5.
Watch out for conflict between the different declarations. They are not easy to debug.

Recommended reading

• Russ Rolfe: Declaring character encodings in CSS
• IANA: Official names for character sets – other names are not allowed; use the preferred name for @charset if more than one name is registered for the same encoding.
• MDN: @charset. There is a support table. I do not trust this. :)
• Test case from the CSS WG.

We usually declare the constant as static. The reason for that is because Java creates copies of non static variables every time you instantiate an object of the class.

So if we make the constants static it would not do so and would save memory.

With final we can make the variable constant.

Hence the best practice to define a constant variable is the following:

private static final String YOUR_CONSTANT = "Some Value"; 

The access modifier can be private/public depending on the business logic.

In command mode: : + 1 will take you to first line

netstat -tapen | grep ssh | awk '{ print $4}'

A simple loop should be working:

for file in /var/*
do
    #whatever you need with "$file"
done

See bash filename expansion

For people who searched for php multidimensional array get values and actually want to solve problem comes from getting one column value from a 2 dimensinal array (like me!), here's a much elegant way than using foreach, which is array_column

For example, if I only want to get hotel_name from the below array, and form to another array:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
    ]
];

I can do this using array_column:

$hotel_name = array_column($hotels, 'hotel_name');

print_r($hotel_name); // Which will give me ['Hotel A', 'Hotel B']

For the actual answer for this question, it can also be beautified by array_column and call_user_func_array('array_merge', $twoDimensionalArray);

Let's make the data in PHP:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 1,
                    'price' => 200
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 2,
                    'price' => 150
                ]
            ],
        ]
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 3,
                    'price' => 900
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 4,
                    'price' => 300
                ]
            ],
        ]
    ]
];

And here's the calculation:

$rooms = array_column($hotels, 'rooms');
$rooms = call_user_func_array('array_merge', $rooms);
$boards = array_column($rooms, 'boards');

foreach($boards as $board){
    $board_id = $board['board_id'];
    $price = $board['price'];
    echo "Board ID is: ".$board_id." and price is: ".$price . "<br/>";
}

Which will give you the following result:

Board ID is: 1 and price is: 200
Board ID is: 2 and price is: 150
Board ID is: 3 and price is: 900
Board ID is: 4 and price is: 300

You could simply use BOOST_REVERSE_FOREACH which iterates backwards. For example, the code

#include <iostream>
#include <boost\foreach.hpp>

int main()
{
    int integers[] = { 0, 1, 2, 3, 4 };
    BOOST_REVERSE_FOREACH(auto i, integers)
    {
        std::cout << i << std::endl;
    }
    return 0;
}

generates the following output:

4

3

2

1

0

This makes it so if before there was a scrollbar then it makes it so the scrollbar has a display of none so you can't see it anymore. You can replace html to body or a class or ID. Hope it works for you :)

html::-webkit-scrollbar {
    display: none;
}

This comment syntax should work for you:

@* enter comments here *@

Or try this one. For me it's working fine:

imageView.setImageDrawable(ContextCompat.getDrawable(this, image));

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

i was having the same issue while generating the classes from wsimport goal. Instead of using jaxws:wsimport goal in eclipse Maven Build i was using clean compile install that was not able to generate code from wsdl file. Thanks to above example. Run jaxws:wsimport goal from Eclipse ide and it will work

COPY table_name FROM 'path/to/data.csv' DELIMITER ',' CSV HEADER;

Most fastest and easy way:

$('#myCheckbox').change(function(){
    alert(this.checked);
});

$el[0].checked;

$el - is jquery element of selection.

Enjoy!

Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct(). Otherwise you get one user multiple times:

users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()

The then() method returns a Promise. It takes two arguments, both are callback functions for the success and failure cases of the Promise. the promise object itself doesn't give you the resolved data directly, the interface of this object only provides the data via callbacks supplied. So, you have to do this like this:

getFeed().then(function(data) { vm.feed = data;});

The then() function returns the promise with a resolved value of the previous then() callback, allowing you the pass the value to subsequent callbacks:

promiseB = promiseA.then(function(result) {
  return result + 1;
});

// promiseB will be resolved immediately after promiseA is resolved
// and its value will be the result of promiseA incremented by 1

Or just call mysql command with --version option.

Boostrap compatible, adust your container width (300px in this example) and you're good to go:

<div class="embed-responsive embed-responsive-16by9" style="height: 100 %; width: 300px; ">
<iframe class="embed-responsive-item" src="https://www.youtube.com/embed/LbLB0K-mXMU?start=1841" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" frameborder="0"></iframe>
</div>

In your codethis refers to the select element not to the selected option

to refer the selected option you can do this -

$(this).find('option:selected').attr("name");

If anyone wonders for the Array version, it goes like this:

int i = Array.FindIndex(yourArray, x => x == itemYouWant);

I would do it this way:

import sys

def main(argv):
    if len(argv) < 2:
        sys.stderr.write("Usage: %s <database>" % (argv[0],))
        return 1

    if not os.path.exists(argv[1]):
        sys.stderr.write("ERROR: Database %r was not found!" % (argv[1],))
        return 1

if __name__ == "__main__":
    sys.exit(main(sys.argv))

This allows main() to be imported into other modules if desired, and simplifies debugging because you can choose what argv should be.

You can use property of d-block here or you can use a parent div with property 'text-center' in bootstrap or 'text-align: center' in css.

Image by default is displayed as inline-block, you need to display it as block in order to center it with .mx-auto. This can be done with built-in .d-block:

<div>
    <img class="mx-auto d-block" src="...">  
</div>

Or leave it as inline-block and wrapped it in a div with .text-center:

<div class="text-center">
    <img src="...">  
</div>

you can get absolute url by calling:

request.original_url

or

request.env['HTTP_REFERER']

Always try to do an associative fetch, that way you can easy get what you want in multiple case result

Here's an example

$result = $mysqli->query("SELECT COUNT(*) AS cityCount FROM myCity")
$row = $result->fetch_assoc();
echo $row['cityCount']." rows in table myCity.";

Loop over Application.Current.Windows[] and find the one with IsActive == true.

Lets get going step by step: first clean project by using

Build->Clean

if this doesn't helps then use your second step

File>Invalidate Caches/Restart...

But the real problem begins when all the above options doesn't works so use your ultimate solution is to close project and go to project location directory and delete

.idea

You can open your project now again.

Working example, try this:

package restclient;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class NetClientGet {
    public static void main(String[] args) {
        try {

            URL url = new URL("http://localhost:3002/RestWebserviceDemo/rest/json/product/dynamicData?size=5");//your url i.e fetch data from .
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");
            conn.setRequestProperty("Accept", "application/json");
            if (conn.getResponseCode() != 200) {
                throw new RuntimeException("Failed : HTTP Error code : "
                        + conn.getResponseCode());
            }
            InputStreamReader in = new InputStreamReader(conn.getInputStream());
            BufferedReader br = new BufferedReader(in);
            String output;
            while ((output = br.readLine()) != null) {
                System.out.println(output);
            }
            conn.disconnect();

        } catch (Exception e) {
            System.out.println("Exception in NetClientGet:- " + e);
        }
    }
}

If you set the margin to be margin:0 auto the image will be centered.

This will give top + bottom a margin of 0, and left and right a margin of 'auto'. Since the div has a width (200px), the image will be 200px wide and the browser will auto set the left and right margin to half of what is left on the page, which will result in the image being centered.

when you have one certificate and 2 different web servers here how I fixed it:

1. List item
2. You should generate certificate at one of the servers as usually in IIS Then at that server you can also complete the certificate in IIS.
3. Run the program DigiCertUtil and export that working certificate
4. Go to the other web server in IIS in security certificates Import that file from step 3.
5. Then use that certificate to create the Binding.

There is now (Chrome 76+ & FF 69+) a Blob.prototype.arrayBuffer() method which will return a Promise resolving with an ArrayBuffer representing the Blob's data.

(async () => {_x000D_
  const blob = new Blob(['hello']);_x000D_
  const buf = await blob.arrayBuffer();_x000D_
  console.log( buf.byteLength ); // 5_x000D_
})();

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

The reason is that your are defining your imageSegment outside of a function in your source code (static variable).

In such cases, the initialization cannot include execution of code, like calling a function or allocation a class. Initializer must be a constant whose value is known at compile time.

You can then initialize your static variable inside of your init method (if you postpone its declaration to init).

I think toEqual is checking deep equal, toBe is the same reference of 2 variable

  it('test me', () => {
    expect([] === []).toEqual(false) // true
    expect([] == []).toEqual(false) // true

    expect([]).toEqual([]); // true // deep check
    expect([]).toBe([]); // false
  })

Add these methods to your Activity:

private MyService myServiceBinder;
public ServiceConnection myConnection = new ServiceConnection() {

    public void onServiceConnected(ComponentName className, IBinder binder) {
        myServiceBinder = ((MyService.MyBinder) binder).getService();
        Log.d("ServiceConnection","connected");
        showServiceData();
    }

    public void onServiceDisconnected(ComponentName className) {
        Log.d("ServiceConnection","disconnected");
        myService = null;
    }
};

public Handler myHandler = new Handler() {
    public void handleMessage(Message message) {
        Bundle data = message.getData();
    }
};

public void doBindService() {
    Intent intent = null;
    intent = new Intent(this, BTService.class);
    // Create a new Messenger for the communication back
    // From the Service to the Activity
    Messenger messenger = new Messenger(myHandler);
    intent.putExtra("MESSENGER", messenger);

    bindService(intent, myConnection, Context.BIND_AUTO_CREATE);
}

And you can bind to service by ovverriding onResume(), and onPause() at your Activity class.

@Override
protected void onResume() {

    Log.d("activity", "onResume");
    if (myService == null) {
        doBindService();
    }
    super.onResume();
}

@Override
protected void onPause() {
    //FIXME put back

    Log.d("activity", "onPause");
    if (myService != null) {
        unbindService(myConnection);
        myService = null;
    }
    super.onPause();
}

Note, that when binding to a service only the onCreate() method is called in the service class. In your Service class you need to define the myBinder method:

private final IBinder mBinder = new MyBinder();
private Messenger outMessenger;

@Override
public IBinder onBind(Intent arg0) {
    Bundle extras = arg0.getExtras();
    Log.d("service","onBind");
    // Get messager from the Activity
    if (extras != null) {
        Log.d("service","onBind with extra");
        outMessenger = (Messenger) extras.get("MESSENGER");
    }
    return mBinder;
}

public class MyBinder extends Binder {
    MyService getService() {
        return MyService.this;
    }
}

After you defined these methods you can reach the methods of your service at your Activity:

private void showServiceData() {  
    myServiceBinder.myMethod();
}

and finally you can start your service when some event occurs like _BOOT_COMPLETED_

public class MyReciever  extends BroadcastReceiver {
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals("android.intent.action.BOOT_COMPLETED")) {
            Intent service = new Intent(context, myService.class);
            context.startService(service);
        }
    }
}

note that when starting a service the onCreate() and onStartCommand() is called in service class and you can stop your service when another event occurs by stopService() note that your event listener should be registerd in your Android manifest file:

<receiver android:name="MyReciever" android:enabled="true" android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
</receiver>

var pattern = new RegExp("^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$");

SELECT only retrieves data from the database, it does not change the table itself.

If you write

SELECT a AS b FROM x

"b" is just an alias name in the query. It does not create an extra column. Your result in the example would only contain one column named "b". But the column in the table would stay "a". "b" is just another name.

I don't really understand what you mean with "so I can use it with each item later on". Do you mean later in the select statement or later in your application. Perhaps you could provide some example code.

To get the all selected Items in a CheckedListBox try this:

In this case ths value is a String but it's run with other type of Object:

for (int i = 0; i < myCheckedListBox.Items.Count; i++)
{
    if (myCheckedListBox.GetItemChecked(i) == true)
    {

        MessageBox.Show("This is the value of ceckhed Item " + myCheckedListBox.Items[i].ToString());

    }

}

If you really mean any and ASCII (not e.g. all Unicode characters):

xxx[\x00-\x7F]+xxx

JavaScript example:

var re = /xxx[\x00-\x7F]+xxx/;

re.test('xxxabcxxx')
// true

re.test('xxx???xxx')
// false

You are getting this error because you are not giving full path. (C:\Users...\file.exe) If you want to remove this error then either give full path or copy that application (you want to open) to the folder where your project(.exe) is present/saved.

You could decompose the date into it's constituent parts and then concatenate them together like this:

The shebang line in any script determines the script's ability to be executed like a standalone executable without typing python beforehand in the terminal or when double clicking it in a file manager (when configured properly). It isn't necessary but generally put there so when someone sees the file opened in an editor, they immediately know what they're looking at. However, which shebang line you use IS important.

Correct usage for Python 3 scripts is:

#!/usr/bin/env python3

This defaults to version 3.latest. For Python 2.7.latest use python2 in place of python3.

The following should NOT be used (except for the rare case that you are writing code which is compatible with both Python 2.x and 3.x):

#!/usr/bin/env python

The reason for these recommendations, given in PEP 394, is that python can refer either to python2 or python3 on different systems. It currently refers to python2 on most distributions, but that is likely to change at some point.

Also, DO NOT Use:

#!/usr/local/bin/python

"python may be installed at /usr/bin/python or /bin/python in those cases, the above #! will fail."

--"#!/usr/bin/env python" vs "#!/usr/local/bin/python"

UPDATED:

You can: create a constant:

private static final DateTimeFormatter DATE_FORMATTER_YYYY_MM_DD =
          DateTimeFormat.forPattern("yyyy-MM-dd"); // or whatever pattern that you need.

This DateTimeFormat is importing from: (be careful with that)

import org.joda.time.format.DateTimeFormat; import org.joda.time.format.DateTimeFormatter;

Parse the Date with:

DateTime.parse(dateTimeScheduled.toString(), DATE_FORMATTER_YYYY_MM_DD);

Before:
DateTime.parse("201711201515",DateTimeFormat.forPattern("yyyyMMddHHmm")).toString("yyyyMMdd");

if want datetime:

DateTime.parse("201711201515", DateTimeFormat.forPattern("yyyyMMddHHmm")).withTimeAtStartOfDay();

I have tried opening the .gitignore file in my vscode, windows 10. There you can see, some previously added ignore files (if any).

To create a new rule to ignore a file with (.js) extension, append the extension of the file like this:

*.js

This will ignore all .js files in your git repository.

To exclude certain type of file from a particular directory, you can add this:

**/foo/*.js

This will ignore all .js files inside only /foo/ directory.

[[ is bash's improvement to the [ command. It has several enhancements that make it a better choice if you write scripts that target bash. My favorites are:

1. It is a syntactical feature of the shell, so it has some special behavior that [ doesn't have. You no longer have to quote variables like mad because [[ handles empty strings and strings with whitespace more intuitively. For example, with [ you have to write

   if [ -f "$file" ]
   

   to correctly handle empty strings or file names with spaces in them. With [[ the quotes are unnecessary:

   if [[ -f $file ]]
   

2. Because it is a syntactical feature, it lets you use && and || operators for boolean tests and < and > for string comparisons. [ cannot do this because it is a regular command and &&, ||, <, and > are not passed to regular commands as command-line arguments.

3. It has a wonderful =~ operator for doing regular expression matches. With [ you might write

   if [ "$answer" = y -o "$answer" = yes ]
   

   With [[ you can write this as

   if [[ $answer =~ ^y(es)?$ ]]
   

   It even lets you access the captured groups which it stores in BASH_REMATCH. For instance, ${BASH_REMATCH[1]} would be "es" if you typed a full "yes" above.

4. You get pattern matching aka globbing for free. Maybe you're less strict about how to type yes. Maybe you're okay if the user types y-anything. Got you covered:

   if [[ $ANSWER = y* ]]
   

Keep in mind that it is a bash extension, so if you are writing sh-compatible scripts then you need to stick with [. Make sure you have the #!/bin/bash shebang line for your script if you use double brackets.

Yes, in principe it is possible, but it doesn't come for free.

I was behind firewall|proxy.

In my case with Studio, ERROR: Gradle sync failed & Cannot find symbol. I have used

You can use the "Network" tab in the browser (shift+ctrl+i) or Firebug.
But an even better solution - in my opinion - is in addition to use an external program such as Fiddler to monitor/catch the traffic between browser and server.

You can load an XML document into an XMLType, then query it, e.g.:

Custom Format for using . is not recognised by Excel, hence that could be the reason it could not sort.

Steps to mitigate; change the format to dd/mm/yyyy, sort as required , change the format to dd.mm.yyyy

If you have control over the input file, and it's an array of objects, you can solve this more easily. Arrange to output the file with each record on one line, like this:

[
   {"key": value},
   {"key": value},
   ...

This is still valid JSON.

Then, use the node.js readline module to process them one line at a time.

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:

interface TestObject {
  name:string;
  value:number;
}

@Component({
  selector: 'app',
  template: `
      <h4>Select Object via 2-way binding</h4>

      <select [ngModel]="selectedObject | json" (ngModelChange)="updateSelectedValue($event)">
        <option *ngFor="#o of objArray" [value]="o | json" >{{o.name}}</option>
      </select>

      <h4>You selected:</h4> {{selectedObject }}
  `,
  directives: [FORM_DIRECTIVES]
})
export class App {
  objArray:TestObject[];
  selectedObject:TestObject;
  constructor(){
    this.objArray = [{name: 'foo', value: 1}, {name: 'bar', value: 1}];
    this.selectedObject = this.objArray[1];
  }
  updateSelectedValue(event:string): void{
    this.selectedObject = JSON.parse(event);
  }
}

PHP Solution

Borrowing directly from Gordon's very comprehensive answer, I note that your question mentions being page-specific in forcing HTTPS/SSL connections.

function forceHTTPS(){
  $httpsURL = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
  if( count( $_POST )>0 )
    die( 'Page should be accessed with HTTPS, but a POST Submission has been sent here. Adjust the form to point to '.$httpsURL );
  if( !isset( $_SERVER['HTTPS'] ) || $_SERVER['HTTPS']!=='on' ){
    if( !headers_sent() ){
      header( "Status: 301 Moved Permanently" );
      header( "Location: $httpsURL" );
      exit();
    }else{
      die( '<script type="javascript">document.location.href="'.$httpsURL.'";</script>' );
    }
  }
}

Then, as close to the top of these pages which you want to force to connect via PHP, you can require() a centralised file containing this (and any other) custom functions, and then simply run the forceHTTPS() function.

HTACCESS / mod_rewrite Solution

I have not implemented this kind of solution personally (I have tended to use the PHP solution, like the one above, for it's simplicity), but the following may be, at least, a good start.

RewriteEngine on

# Check for POST Submission
RewriteCond %{REQUEST_METHOD} !^POST$

# Forcing HTTPS
RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{SERVER_PORT} 80
# Pages to Apply
RewriteCond %{REQUEST_URI} ^something_secure [OR]
RewriteCond %{REQUEST_URI} ^something_else_secure
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

# Forcing HTTP
RewriteCond %{HTTPS} =on [OR]
RewriteCond %{SERVER_PORT} 443
# Pages to Apply
RewriteCond %{REQUEST_URI} ^something_public [OR]
RewriteCond %{REQUEST_URI} ^something_else_public
RewriteRule .* http://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

In iOS 5, the Manifest.mbdx file was eliminated. For the purpose of this article, it was redundant anyway, because the domain and path are in Manifest.mbdb and the ID hash can be generated with SHA1.

Here is my update of galloglass's code so it works with backups of iOS 5 devices. The only changes are elimination of process_mbdx_file() and addition of a few lines in process_mbdb_file().

Tested with backups of an iPhone 4S and an iPad 1, both with plenty of apps and files.

I suggest reviewing CWE/SANS TOP 25 Most Dangerous Programming Errors. It was updated for 2010 with the promise of regular updates in the future. The 2009 revision is available as well.

From http://cwe.mitre.org/top25/index.html

The 2010 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most widespread and critical programming errors that can lead to serious software vulnerabilities. They are often easy to find, and easy to exploit. They are dangerous because they will frequently allow attackers to completely take over the software, steal data, or prevent the software from working at all.

The Top 25 list is a tool for education and awareness to help programmers to prevent the kinds of vulnerabilities that plague the software industry, by identifying and avoiding all-too-common mistakes that occur before software is even shipped. Software customers can use the same list to help them to ask for more secure software. Researchers in software security can use the Top 25 to focus on a narrow but important subset of all known security weaknesses. Finally, software managers and CIOs can use the Top 25 list as a measuring stick of progress in their efforts to secure their software.

The difference can be illustrated by the following:

std::cout << std::endl;

is equivalent to

std::cout << '\n' << std::flush;

So,

• Use std::endl If you want to force an immediate flush to the output.
• Use \n if you are worried about performance (which is probably not the case if you are using the << operator).

I use \n on most lines.
Then use std::endl at the end of a paragraph (but that is just a habit and not usually necessary).

Contrary to other claims, the \n character is mapped to the correct platform end of line sequence only if the stream is going to a file (std::cin and std::cout being special but still files (or file-like)).

You can use floating:

<div class="paragraphs">
  <div class="row">
    <div class="span4">
      <img style="float:left" src="../site/img/success32.png"/>
      <div class="content-heading"><h3>Experience &nbsp </h3></div>
      <p style="clear:both">Donec id elit non mi porta gravida at eget metus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui.</p>
    </div>
  </div>
</div>

If you want the following <p> to stay at the same line too, remove its

style="clear:both"

but then you should add

<div style="clear:both"></div>

after it.

select * from t where year(Columnx) = 2010

Have you tried with Pandoc?

EDIT:

Although the documentation has become a bit complex, pandoc has supported inline LaTeX and LaTeX templates for 10 years.

Documents like the following one can be written in Markdown:

---
title: Just say hello!
author: My Friend
header-includes: |
    \usepackage{tikz,pgfplots}
    \usepackage{fancyhdr}
    \pagestyle{fancy}
    \fancyhead[CO,CE]{This is fancy}
    \fancyfoot[CO,CE]{So is this}
    \fancyfoot[LE,RO]{\thepage}
abstract: This is a pandoc test with Markdown + inline LaTeX
---

Just say hello!
===============

This could be a good example or inlined \LaTeX:

\begin{tikzpicture}
\begin{axis}
\addplot[color=red]{exp(x)};
\end{axis}
\end{tikzpicture}
%Here ends the furst plot
\hskip 5pt
%Here begins the 3d plot
\begin{tikzpicture}
\begin{axis}
\addplot3[
    surf,
]
{exp(-x^2-y^2)*x};
\end{axis}
\end{tikzpicture}

And now, just a few words to terminate:

> Goodbye folks!

Which can be converted to LaTeX using commands like this: pandoc -s -i Hello.md -o Hello.tex

Following is an image of the converted Hello.md to Hello.pdf file using MiKTeX as LaTeX processor with the command: pandoc -s -i Hello.md -o Hello.pdf

Finally, there are some open source LaTeX templates like this one: https://github.com/Wandmalfarbe/pandoc-latex-template, that can be used for better formatting.

As always, the reader should dig deeper if he has less trivial use cases than presented here.

If you use request.getPathInfo() inside a Filter, you always seem to get null (at least with jetty).

This terse invalid bug + response alludes to the issue I think:

https://issues.apache.org/bugzilla/show_bug.cgi?id=28323

I suspect it is related to the fact that filters run before the servlet gets the request. It may be a container bug, or expected behaviour that I haven't been able to identify.

The contextPath is available though, so fforws solution works even in filters. I don't like having to do it by hand, but the implementation is broken or

As the rank doesn't depend at all from the contacts

RANKED_RSLTS

 QRY_ID  |  RES_ID  |  SCORE |  RANK
-------------------------------------
   A     |    1     |    15  |   3
   A     |    2     |    32  |   1
   A     |    3     |    29  |   2
   C     |    7     |    61  |   1
   C     |    9     |    30  |   2

Thus :

SELECT
    C.*
    ,R.SCORE
    ,MYRANK
FROM CONTACTS C LEFT JOIN
(SELECT  *,

AND C.QRY_ID = R.QRY_ID

Use the CSS function from jQuery to set styles to your items :

$('#buttonId').css({ "background-color": 'brown'});

Combining a couple answers above:

function isVisible (ele) {
    var style = window.getComputedStyle(ele);
    return  style.width !== "0" &&
    style.height !== "0" &&
    style.opacity !== "0" &&
    style.display!=='none' &&
    style.visibility!== 'hidden';
}

Like AlexZ said, this may be slower than some of your other options if you know more specifically what you're looking for, but this should catch all of the main ways elements are hidden.

But, it also depends what counts as visible for you. Just for example, a div's height can be set to 0px but the contents still visible depending on the overflow properties. Or a div's contents could be made the same color as the background so it is not visible to users but still rendered on the page. Or a div could be moved off screen or hidden behind other divs, or it's contents could be non-visible but the border still visible. To a certain extent "visible" is a subjective term.

I had to:

• Create a local administrator
• Add a Microsoft Loopback adapter
• Reference the location as \\127.0.0.1\SSRSFileShare

you might also want to change your font size for other parts of the IDE (other than the code).

Just add the parameter --fontsize <size> (default size is 11) to the startup command.

You can put it into the command line when launching IDE. You can also put it into the netbeans.conf file, which is in the /etc subdirectory of NetBeans installation.

Just place it as a last parameter into the netbeans_default_options parameter.

For anyone who may stumble across this old question ...

There is one thing that I think needs to be addressed.

~/.nanorc is used to apply your user specific settings to nano, so if you are editing files that require the use of sudo nano for permissions then this is not going to work.

When using sudo your custom user configuration files will not be loaded when opening a program, as you are not running the program from your account so none of your configuration changes in ~/.nanorc will be applied.

If this is the situation you find yourself in (wanting to run sudo nano and use your own config settings) then you have three options :

• using command line flags when running sudo nano
• editing the /root/.nanorc file
• editing the /etc/nanorc global config file

Keep in mind that /etc/nanorc is a global configuration file and as such it affects all users, which may or may not be a problem depending on whether you have a multi-user system.

Also, user config files will override the global one, so if you were to edit /etc/nanorc and ~/.nanorc with different settings, when you run nano it will load the settings from ~/.nanorc but if you run sudo nano then it will load the settings from /etc/nanorc.

Same goes for /root/.nanorc this will override /etc/nanorc when running sudo nano

Using flags is probably the best option unless you have a lot of options.

What you are trying to deserialize to a Dictionary is actually a Javascript object serialized to JSON. In Javascript, you can use this object as an associative array, but really it's an object, as far as the JSON standard is concerned.

So you would have no problem deserializing what you have with a standard JSON serializer (like the .net ones, DataContractJsonSerializer and JavascriptSerializer) to an object (with members called AppName, AnotherAppName, etc), but to actually interpret this as a dictionary you'll need a serializer that goes further than the Json spec, which doesn't have anything about Dictionaries as far as I know.

One such example is the one everybody uses: JSON .net

There is an other solution if you don't want to use an external lib, which is to convert your Javascript object to a list before serializing it to JSON.

var myList = [];
$.each(myObj, function(key, value) { myList.push({Key:key, Value:value}) });

now if you serialize myList to a JSON object, you should be capable of deserializing to a List<KeyValuePair<string, ValueDescription>> with any of the aforementioned serializers. That list would then be quite obvious to convert to a dictionary.

Note: ValueDescription being this class:

public class ValueDescription
{
    public string Description { get; set; }
    public string Value { get; set; }
}

 select persons.personsid,name,info.id,address
    -> from persons
    -> inner join persons on info.infoid = info.info.id;

New-style classes (i.e. subclassed from object, which is the default in Python 3) have a __subclasses__ method which returns the subclasses:

class Foo(object): pass
class Bar(Foo): pass
class Baz(Foo): pass
class Bing(Bar): pass

Here are the names of the subclasses:

print([cls.__name__ for cls in Foo.__subclasses__()])
# ['Bar', 'Baz']

Here are the subclasses themselves:

print(Foo.__subclasses__())
# [<class '__main__.Bar'>, <class '__main__.Baz'>]

Confirmation that the subclasses do indeed list Foo as their base:

for cls in Foo.__subclasses__():
    print(cls.__base__)
# <class '__main__.Foo'>
# <class '__main__.Foo'>

Note if you want subsubclasses, you'll have to recurse:

def all_subclasses(cls):
    return set(cls.__subclasses__()).union(
        [s for c in cls.__subclasses__() for s in all_subclasses(c)])

print(all_subclasses(Foo))
# {<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>}

Note that if the class definition of a subclass hasn't been executed yet - for example, if the subclass's module hasn't been imported yet - then that subclass doesn't exist yet, and __subclasses__ won't find it.

You mentioned "given its name". Since Python classes are first-class objects, you don't need to use a string with the class's name in place of the class or anything like that. You can just use the class directly, and you probably should.

If you do have a string representing the name of a class and you want to find that class's subclasses, then there are two steps: find the class given its name, and then find the subclasses with __subclasses__ as above.

How to find the class from the name depends on where you're expecting to find it. If you're expecting to find it in the same module as the code that's trying to locate the class, then

cls = globals()[name]

would do the job, or in the unlikely case that you're expecting to find it in locals,

cls = locals()[name]

If the class could be in any module, then your name string should contain the fully-qualified name - something like 'pkg.module.Foo' instead of just 'Foo'. Use importlib to load the class's module, then retrieve the corresponding attribute:

import importlib
modname, _, clsname = name.rpartition('.')
mod = importlib.import_module(modname)
cls = getattr(mod, clsname)

However you find the class, cls.__subclasses__() would then return a list of its subclasses.

Running PHP as a CGI means that you basically tell your web server the location of the PHP executable file, and the server runs that executable

whereas

PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that allows a website to handle strenuous loads. PHP-FPM maintains pools (workers that can respond to PHP requests) to accomplish this. PHP-FPM is faster than traditional CGI-based methods, such as SUPHP, for multi-user PHP environments

However, there are pros and cons to both and one should choose as per their specific use case.

I found info on this link for fastcgi vs fpm quite helpful in choosing which handler to use in my scenario.

I think you are a bit confused on the purpose of custom data attributes. From the w3 spec

Custom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements.

By itself an attribute of data-toggle=value is basically a key-value pair, in which the key is "data-toggle" and the value is "value".

In the context of Bootstrap, the custom data in the attribute is almost useless without the context that their JavaScript library includes for the data. If you look at the non-minified version of bootstrap.js then you can do a search for "data-toggle" and find how it is being used.

Here is an example of Bootstrap JavaScript code that I copied straight from the file regarding the use of "data-toggle".

• Button Toggle

  Button.prototype.toggle = function () {
    var changed = true
    var $parent = this.$element.closest('[data-toggle="buttons"]')
  
    if ($parent.length) {
      var $input = this.$element.find('input')
      if ($input.prop('type') == 'radio') {
        if ($input.prop('checked') && this.$element.hasClass('active')) changed = false
        else $parent.find('.active').removeClass('active')
      }
      if (changed) $input.prop('checked', !this.$element.hasClass('active')).trigger('change')
    } else {
      this.$element.attr('aria-pressed', !this.$element.hasClass('active'))
    }
  
    if (changed) this.$element.toggleClass('active')
  }
  

The context that the code provides shows that Bootstrap is using the data-toggle attribute as a custom query selector to process the particular element.

From what I see these are the data-toggle options:

• collapse
• dropdown
• modal
• tab
• pill
• button(s)

You may want to look at the Bootstrap JavaScript documentation to get more specifics of what each do, but basically the data-toggle attribute toggles the element to active or not.

old question that I stumbled into that I believe deserves an update... You can infact execute javascript from the URL, and you can get creative about it too. I recently made a members only area that I wanted to remind someone what their password was, so I was looking for a non-local alert...of course you can embed an alert into the page itself, but then its public. the difference here is I can create a link and slip some JS into the href so clicking on the link will generate the alert.

here is what I mean >>

<a href="javascript:alert('the secret is to ask.');window.location.replace('http://google.com');">You can have anything</a>

and so upon clicking the link, the user is given an alert with the info, then they are taken to the new page.

obviously you could also write an onClick, but the href works just fine when you slip it through the URL, just remember to prepend it with "javascript:"

*works in chrome, didnt check anything else.

<script>
  function submit(){
      var userPass = document.getElementById('pass');
      var userName = document.getElementById('user');
      alert(user.value);
      alert(pass.value);
  }
</script>

<input type="text" id="user" />
<input type="text" id="pass" />
<button onclick="submit();" href="javascript:;">Submit</button>

I see you're having issues with the social share links. I had a similar issue at some point and found this question, but I don't see a complete answer for it. I hope my javascript resolution from below will help:

I had default sharing links that needed to be modified so that the URL that's being shared will have additional UTM parameters concatenated.

My example will be for the Facebook social share link, but it works for all the possible social sharing network links:

The URL that needed to be shared was:

https://mywebsitesite.com/blog/post-name

The default sharing link looked like:

$facebook_default = "https://www.facebook.com/sharer.php?u=https%3A%2F%2mywebsitesite.com%2Fblog%2Fpost-name%2F&t=hello"

I first DECODED it:

console.log( decodeURIComponent($facebook_default) );
=>
https://www.facebook.com/sharer.php?u=https://mywebsitesite.com/blog/post-name/&t=hello

Then I replaced the URL with the encoded new URL (with the UTM parameters concatenated):

console.log( decodeURIComponent($facebook_default).replace( window.location.href, encodeURIComponent(window.location.href+'?utm_medium=social&utm_source=facebook')) );

=>

https://www.facebook.com/sharer.php?u=https%3A%2F%mywebsitesite.com%2Fblog%2Fpost-name%2F%3Futm_medium%3Dsocial%26utm_source%3Dfacebook&t=2018

That's it!

Complete solution:

$facebook_default = $('a.facebook_default_link').attr('href');

$('a.facebook_default_link').attr( 'href', decodeURIComponent($facebook_default).replace( window.location.href, encodeURIComponent(window.location.href+'?utm_medium=social&utm_source=facebook')) );

everyone has answered excellently using the date, let me try to answer it using pandas

dt = pd.to_datetime('2008/08/18', format='%Y/%m/%d')
dt1 = pd.to_datetime('2008/09/26', format='%Y/%m/%d')

(dt1-dt).days

This will give the answer. In case one of the input is dataframe column. simply use dt.days in place of days

(dt1-dt).dt.days

something like that?

'nearest
 n = 5
 'n = 10

 'value
 v = 496
 'v = 499 
 'v = 2348 
 'v = 7343

 'mod
 m = (v \ n) * n

 'diff between mod and the val
 i = v-m


 if i >= (n/2) then     
      msgbox m+n
 else
      msgbox m
 end if

$Date3 = date('y-m-d');
$Date2 = date('y-m-d', strtotime("-7 days"));

SELECT * FROM disaster WHERE date BETWEEN '".$Date2."' AND  '".$Date3."'

These are the necersary imports:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");

String readFile(String fileName) throws IOException {
    BufferedReader br = new BufferedReader(new FileReader(fileName));
    try {
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();

        while (line != null) {
            sb.append(line);
            sb.append("\n");
            line = br.readLine();
        }
        return sb.toString();
    } finally {
        br.close();
    }
}

If your application is speed critical i will advice using [] operator because it creates total 3 copies of the original object out of which 2 are temporary objects and sooner or later destroyed as.

But in insert(), 4 copies of the original object are created out of which 3 are temporary objects( not necessarily "temporaries") and are destroyed.

Which means extra time for: 1. One objects memory allocation 2. One extra constructor call 3. One extra destructor call 4. One objects memory deallocation

If your objects are large, constructors are typical, destructors do a lot of resource freeing, above points count even more. Regarding readability, i think both are fair enough.

The same question came into my mind but not over readability but speed. Here is a sample code through which I came to know about the point i mentioned.

class Sample
{
    static int _noOfObjects;

    int _objectNo;
public:
    Sample() :
        _objectNo( _noOfObjects++ )
    {
        std::cout<<"Inside default constructor of object "<<_objectNo<<std::endl;
    }

    Sample( const Sample& sample) :
    _objectNo( _noOfObjects++ )
    {
        std::cout<<"Inside copy constructor of object "<<_objectNo<<std::endl;
    }

    ~Sample()
    {
        std::cout<<"Destroying object "<<_objectNo<<std::endl;
    }
};
int Sample::_noOfObjects = 0;


int main(int argc, char* argv[])
{
    Sample sample;
    std::map<int,Sample> map;

    map.insert( std::make_pair<int,Sample>( 1, sample) );
    //map[1] = sample;
    return 0;
}

I ran into this issue today. Here is my hacky solution.

I needed a fixed position element to transition up by 100 pixels as it loaded.

var delay = (ms) => new Promise(res => setTimeout(res, ms));
async function animateView(startPosition,elm){
  for(var i=0; i<101; i++){
    elm.style.top = `${(startPosition-i)}px`;
    await delay(1);
  }
}

Try the following:

driver.find_elements_by_xpath("//*[contains(text(), 'My Button')]")

use indexOf() function

string s = "Error description, code : -1";
int index = s.indexOf("code");
if(index != -1)
{
  //DO YOUR LOGIC
  string errorCode = s.Substring(index+4);
}

Just to add a bit to Darin's example, the below will show an icon with the boxes. http://msdn.microsoft.com/en-us/library/system.windows.forms.messagebox(v=vs.110).aspx

Dim result = MessageBox.Show("Message To Display", "MessageBox Title", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question)

If result = DialogResult.Cancel Then

    MessageBox.Show("Cancel Button Pressed", "MessageBox Title",MessageBoxButtons.OK , MessageBoxIcon.Exclamation)

ElseIf result = DialogResult.No Then

    MessageBox.Show("No Button Pressed", "MessageBox Title", MessageBoxButtons.OK, MessageBoxIcon.Error)

ElseIf result = DialogResult.Yes Then

    MessageBox.Show("Yes Button Pressed", "MessageBox Title", MessageBoxButtons.OK, MessageBoxIcon.Information)

End If

new[,2] is a factor, not a numeric vector. Transform it first

new$MY_NEW_COLUMN <-as.numeric(as.character(new[,2])) * 5

The syntax you are using is new to SQL Server 2008:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1000,N'test'),(1001,N'test2')

For SQL Server 2005, you will have to use multiple INSERT statements:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1000,N'test')

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1001,N'test2')

One other option is to use UNION ALL:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
SELECT 1000, N'test' UNION ALL
SELECT 1001, N'test2'

To understand queue method, you have to understand how jQuery does animation. If you write multiple animate method calls one after the other, jQuery creates an 'internal' queue and adds these method calls to it. Then it runs those animate calls one by one.

Consider following code.

function nonStopAnimation()
{
    //These multiple animate calls are queued to run one after
    //the other by jQuery.
    //This is the reason that nonStopAnimation method will return immeidately
    //after queuing these calls. 
    $('#box').animate({ left: '+=500'}, 4000);
    $('#box').animate({ top: '+=500'}, 4000);
    $('#box').animate({ left: '-=500'}, 4000);

    //By calling the same function at the end of last animation, we can
    //create non stop animation. 
    $('#box').animate({ top: '-=500'}, 4000 , nonStopAnimation);
}

The 'queue'/'dequeue' method gives you control over this 'animation queue'.

By default the animation queue is named 'fx'. I have created a sample page here which has various examples which will illustrate how the queue method could be used.

http://jsbin.com/zoluge/1/edit?html,output

Code for above sample page:

$(document).ready(function() {
    $('#nonStopAnimation').click(nonStopAnimation);

    $('#stopAnimationQueue').click(function() {
        //By default all animation for particular 'selector'
        //are queued in queue named 'fx'.
        //By clearning that queue, you can stop the animation.
        $('#box').queue('fx', []);
    });

    $('#addAnimation').click(function() {
        $('#box').queue(function() {
            $(this).animate({ height : '-=25'}, 2000);
            //De-queue our newly queued function so that queues
            //can keep running.
            $(this).dequeue();
        });
    });

    $('#stopAnimation').click(function() {
        $('#box').stop();
    });

    setInterval(function() {
        $('#currentQueueLength').html(
         'Current Animation Queue Length for #box ' + 
          $('#box').queue('fx').length
        );
    }, 2000);
});

function nonStopAnimation()
{
    //These multiple animate calls are queued to run one after
    //the other by jQuery.
    $('#box').animate({ left: '+=500'}, 4000);
    $('#box').animate({ top: '+=500'}, 4000);
    $('#box').animate({ left: '-=500'}, 4000);
    $('#box').animate({ top: '-=500'}, 4000, nonStopAnimation);
}

Now you may ask, why should I bother with this queue? Normally, you wont. But if you have a complicated animation sequence which you want to control, then queue/dequeue methods are your friend.

Also see this interesting conversation on jQuery group about creating a complicated animation sequence.

http://groups.google.com/group/jquery-en/browse_thread/thread/b398ad505a9b0512/f4f3e841eab5f5a2?lnk=gst

Demo of the animation:

Let me know if you still have questions.

I found one solution and it does not require to define runnable or other things and it's working fine.

    var lastTouchTime: Long = 0

    // ( ViewConfiguration.#.DEFAULT_LONG_PRESS_TIMEOUT =500)
    val longPressTime = 500

    var lastTouchX = 0f
    var lastTouchY = 0f

    view.setOnTouchListener { v, event ->

        when (event.action) {
            MotionEvent.ACTION_DOWN -> {
                lastTouchTime = SystemClock.elapsedRealtime()
                lastTouchX = event.x
                lastTouchY = event.y
                return@setOnTouchListener true
            }
            MotionEvent.ACTION_UP -> {
                if (SystemClock.elapsedRealtime() - lastTouchTime > longPressTime
                        && Math.abs(event.x - lastTouchX) < 3
                        && Math.abs(event.y - lastTouchY) < 3) {
                    Log.d(TAG, "Long press")
                }
                return@setOnTouchListener true
            }
            else -> {
                return@setOnTouchListener false
            }
        }

    }

You're close... but use: if (Value1.StartsWith("abc"))

Here is a function that works with jQuery (for height only, not width):

function setHeight(jq_in){
    jq_in.each(function(index, elem){
        // This line will work with pure Javascript (taken from NicB's answer):
        elem.style.height = elem.scrollHeight+'px'; 
    });
}
setHeight($('<put selector here>'));

Note: The op asked for a solution that does not use Javascript, however this should be helpful to many people who come across this question.

In R the equivalent function is seq and you can use it with the option by:

seq(from = 5, to = 100, by = 5)
# [1]   5  10  15  20  25  30  35  40  45  50  55  60  65  70  75  80  85  90  95 100

In addition to by you can also have other options such as length.out and along.with.

length.out: If you want to get a total of 10 numbers between 0 and 1, for example:

seq(0, 1, length.out = 10)
# gives 10 equally spaced numbers from 0 to 1

along.with: It takes the length of the vector you supply as input and provides a vector from 1:length(input).

seq(along.with=c(10,20,30))
# [1] 1 2 3

Although, instead of using the along.with option, it is recommended to use seq_along in this case. From the documentation for ?seq

seq is generic, and only the default method is described here. Note that it dispatches on the class of the first argument irrespective of argument names. This can have unintended consequences if it is called with just one argument intending this to be taken as along.with: it is much better to use seq_along in that case.

seq_along: Instead of seq(along.with(.))

seq_along(c(10,20,30))
# [1] 1 2 3

Hope this helps.

I have the same problem but I found this after a long search: http://www.herongyang.com/JDBC/MySQL-JDBC-Driver-Load-Class.html

But I made some change. I put the driver in the same folder as my ConTest.java file, and compile it, resulting in ConTest.class.

So in this folder have

ConTest.class
mysql-connector-java-5.1.14-bin.jar

and I write this

java -cp .;mysql-connector-java-5.1.14-bin.jar ConTest

This way if you not use any IDE just cmd in windows or shell in linux.

For now I have resolved the issue by using the Linux utility s3cmd. I used it like this in Python:

delFile = 's3cmd -c /home/project/.s3cfg del s3://images/anon-images/small/' + filename
os.system(delFile)

The following code uses both data.table and fastmatch for increased speed.

library("data.table")
library("fastmatch")

a1 <- setDT(data.frame(a = 1:5, b=letters[1:5]))
a2 <- setDT(data.frame(a = 1:3, b=letters[1:3]))

compare_rows <- a1$a %fin% a2$a
# the %fin% function comes from the `fastmatch` package

added_rows <- a1[which(compare_rows == FALSE)]

added_rows

#    a b
# 1: 4 d
# 2: 5 e

I think you can use vue-cli

If you are using Vue CLI along with a backend framework that handles static assets as part of its deployment, all you need to do is making sure Vue CLI generates the built files in the correct location, and then follow the deployment instruction of your backend framework.

If you are developing your frontend app separately from your backend - i.e. your backend exposes an API for your frontend to talk to, then your frontend is essentially a purely static app. You can deploy the built content in the dist directory to any static file server, but make sure to set the correct baseUrl

cPickle comes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle, you can do this:

>>> import _pickle as cPickle

However, in 3.x, it's easier just to use pickle.

No need to install anything. If something requires cPickle in python 3.x, then that's probably a bug.

The simple way

Change to the database directory:

cd /var/lib/mysql/

Shut down MySQL... This is important!

/etc/init.d/mysql stop

Okay, this way doesn't work for InnoDB or BDB-Databases.

Rename database:

mv old-name new-name

...or the table...

cd database/

mv old-name.frm new-name.frm

mv old-name.MYD new-name.MYD

mv old-name.MYI new-name.MYI

Restart MySQL

/etc/init.d/mysql start

Done...

OK, this way doesn't work with InnoDB or BDB databases. In this case you have to dump the database and re-import it.

You can replace the items at specific position using set method of ArrayList as below:

list.set( your_index, your_item );

But the element should be present at the index you are passing inside set() method else it will throw exception.

With google's Gson 2.7 (probably earlier versions too, but I tested 2.7) it's as simple as:

Map map = gson.fromJson(json, Map.class);

Which returns a Map of type class com.google.gson.internal.LinkedTreeMap and works recursively on nested objects.

I would make a minor change to Frederik's solution. I would use the sp_spaceused system stored procedure which will also include data and index sizes.

declare c_tables cursor fast_forward for 
select table_name from information_schema.tables 

open c_tables 
declare @tablename varchar(255) 
declare @stmt nvarchar(2000) 
declare @rowcount int 
fetch next from c_tables into @tablename 

while @@fetch_status = 0 
begin 

    select @stmt = 'sp_spaceused ' + @tablename 

    exec sp_executesql @stmt

    fetch next from c_tables into @tablename 

end 

close c_tables 
deallocate c_tables 

Another option

tuple([tuple(row) for row in myarray])

If you are passing NumPy arrays to C++ functions, you may also wish to look at using Cython or SWIG.

How can I declare a class type, so that I ensure the object is a constructor of a general class?

A Constructor type could be defined as:

 type AConstructorTypeOf<T> = new (...args:any[]) => T;

 class A { ... }

 function factory(Ctor: AConstructorTypeOf<A>){
   return new Ctor();
 }

const aInstance = factory(A);

Direct value should work just fine:

var sel = document.getElementsByName('item');
var sv = sel.value;
alert(sv);

The only reason your code might fail is when there is no item selected, then the selectedIndex returns -1 and the code breaks.

try this:

HTML:

<div class="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
  <div class="item">5</div>
</div>

CSS:

.container {
  width: 200px;
  height: 100px;
  display: flex;
  overflow-x: auto;
}

.item {
  width: 100px;
  flex-shrink: 0;
  height: 100px;
}

The white-space: nowrap; property dont let you wrap text. Just see here for an example: https://codepen.io/oezkany/pen/YoVgYK

CSS layouts are generally much better for accessibility, provided the content comes in a natural order and makes sense without a stylesheet. And it's not just screen readers that struggle with table-based layouts: they also make it much harder for mobile browsers to render a page properly.

Also, with a div-based layout you can very easily do cool things with a print stylesheet such as excluding headers, footers and navigation from printed pages - I think it would be impossible, or at least much more difficult, to do that with a table-based layout.

If you're doubting that separation of content from layout is easier with divs than with tables, take a look at the div-based HTML at CSS Zen Garden, see how changing the stylesheets can drastically change the layout, and think about whether you could achieve the same variety of layouts if the HTML was table based... If you're doing a table-based layout, you're unlikely to be using CSS to control all the spacing and padding in the cells (if you were, you'd almost certainly find it easier to use floating divs etc. in the first place). Without using CSS to control all that, and because of the fact that tables specify the left-to-right and top-to bottom order of things in the HTML, tables tend to mean that your layout becomes very much fixed in the HTML.

Realistically I think it's very hard to completely change the layout of a div-and-CSS-based design without changing the divs a bit. However, with a div-and-CSS-based layout it's much easier to tweak things like the spacing between various blocks, and their relative sizes.

The request type is multipart/form-data and what you are sending is essentially form fields that go out as bytes with content boundaries separating different form fields.To send an object representation as form field (string), you can send a serialized form from the client that you can then deserialize on the server.

After all no programming environment object is actually ever traveling on the wire. The programming environment on both side are just doing automatic serialization and deserialization that you can also do. That is the cleanest and programming environment quirks free way to do it.

As an example, here is a javascript client posting to a Jersey example service,

submitFile(){

    let data = new FormData();
    let account = {
        "name": "test account",
        "location": "Bangalore"
    }

    data.append('file', this.file);
    data.append("accountKey", "44c85e59-afed-4fb2-884d-b3d85b051c44");
    data.append("device", "test001");
    data.append("account", JSON.stringify(account));
    
    let url = "http://localhost:9090/sensordb/test/file/multipart/upload";

    let config = {
        headers: {
            'Content-Type': 'multipart/form-data'
        }
    }

    axios.post(url, data, config).then(function(data){
        console.log('SUCCESS!!');
        console.log(data.data);
    }).catch(function(){
        console.log('FAILURE!!');
    });
},

Here the client is sending a file, 2 form fields (strings) and an account object that has been stringified for transport. here is how the form fields look on the wire,

On the server, you can just deserialize the form fields the way you see fit. To finish this trivial example,

    @POST
@Path("/file/multipart/upload")
@Consumes({MediaType.MULTIPART_FORM_DATA})
public Response uploadMultiPart(@Context ContainerRequestContext requestContext,
        @FormDataParam("file") InputStream fileInputStream,
        @FormDataParam("file") FormDataContentDisposition cdh,
        @FormDataParam("accountKey") String accountKey,
        @FormDataParam("account") String json)  {
    

    
    System.out.println(cdh.getFileName());
    System.out.println(cdh.getName());
    System.out.println(accountKey);
    
    try {
        Account account = Account.deserialize(json);
        System.out.println(account.getLocation());
        System.out.println(account.getName());
        
    } catch (Exception e) {
        e.printStackTrace();
    }
    
    return Response.ok().build();
    
}

Set the resize property to both. Then you can change width and height like this:

.classname img{
  resize: both;
  width:50px;
  height:25px;
}

By using EntityManager, code is no longer tightly coupled with hibernate. But for this, in usage we should use :

javax.persistence.EntityManager

instead of

org.hibernate.ejb.HibernateEntityManager

Similarly, for EntityManagerFactory, use javax interface. That way, the code is loosely coupled. If there is a better JPA 2 implementation than hibernate, switching would be easy. In extreme case, we could type cast to HibernateEntityManager.

like the answer above but I have a duplicate record so I have to create a subquery with distinct

Select user_id
(
   select distinct userid
   from yourtable
   where user_id = @userid

) t1
where 
ancestry in ('England', 'France', 'Germany')
group by user_id
having count(user_id) = 3

this is what I used because I have multiple record(download logs) and this checks that all the required files have been downloaded

I found things not to like about all the above solutions, so I came up with my own. This version makes sure parts are joined with a single slash and leaves leading and trailing slashes alone. No pip install, no urllib.parse.urljoin weirdness.

In [1]: from functools import reduce

In [2]: def join_slash(a, b):
   ...:     return a.rstrip('/') + '/' + b.lstrip('/')
   ...:

In [3]: def urljoin(*args):
   ...:     return reduce(join_slash, args) if args else ''
   ...:

In [4]: parts = ['https://foo-bar.quux.net', '/foo', 'bar', '/bat/', '/quux/']

In [5]: urljoin(*parts)
Out[5]: 'https://foo-bar.quux.net/foo/bar/bat/quux/'

In [6]: urljoin('https://quux.com/', '/path', 'to/file///', '//here/')
Out[6]: 'https://quux.com/path/to/file/here/'

In [7]: urljoin()
Out[7]: ''

In [8]: urljoin('//','beware', 'of/this///')
Out[8]: '/beware/of/this///'

In [9]: urljoin('/leading', 'and/', '/trailing/', 'slash/')
Out[9]: '/leading/and/trailing/slash/'

To delete a cookie I set it again with an empty value and expiring in 1 second. In details, I always use one of the following flavours (I tend to prefer the second one):

1.

    function setCookie(key, value, expireDays, expireHours, expireMinutes, expireSeconds) {
        var expireDate = new Date();
        if (expireDays) {
            expireDate.setDate(expireDate.getDate() + expireDays);
        }
        if (expireHours) {
            expireDate.setHours(expireDate.getHours() + expireHours);
        }
        if (expireMinutes) {
            expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
        }
        if (expireSeconds) {
            expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
        }
        document.cookie = key +"="+ escape(value) +
            ";domain="+ window.location.hostname +
            ";path=/"+
            ";expires="+expireDate.toUTCString();
    }

    function deleteCookie(name) {
        setCookie(name, "", null , null , null, 1);
    }

Usage:

setCookie("reminder", "buyCoffee", null, null, 20);
deleteCookie("reminder");

2

    function setCookie(params) {
        var name            = params.name,
            value           = params.value,
            expireDays      = params.days,
            expireHours     = params.hours,
            expireMinutes   = params.minutes,
            expireSeconds   = params.seconds;

        var expireDate = new Date();
        if (expireDays) {
            expireDate.setDate(expireDate.getDate() + expireDays);
        }
        if (expireHours) {
            expireDate.setHours(expireDate.getHours() + expireHours);
        }
        if (expireMinutes) {
            expireDate.setMinutes(expireDate.getMinutes() + expireMinutes);
        }
        if (expireSeconds) {
            expireDate.setSeconds(expireDate.getSeconds() + expireSeconds);
        }

        document.cookie = name +"="+ escape(value) +
            ";domain="+ window.location.hostname +
            ";path=/"+
            ";expires="+expireDate.toUTCString();
    }

    function deleteCookie(name) {
        setCookie({name: name, value: "", seconds: 1});
    }

Usage:

setCookie({name: "reminder", value: "buyCoffee", minutes: 20});
deleteCookie("reminder");

In my case eclipse.ini entry for --launcher.library was :

--launcher.library C:\Users\UserName\.p2\pool\plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834

and on my machine 'C:\Users\UserName\.p2\' folder was missing hence installed the eclipse again which created the .p2 folder structure at required location and now I am able to login successfully.

In the command prompt, type the command below and press Enter.

bcdedit /enum

Under the Windows Boot Loader sections, make note of the identifier value.

To start in safe mode from command prompt :

bcdedit /set {identifier} safeboot minimal 

Then enter the command line to reboot your computer.

Here is the complete source code of an example using JSch without having to worry about the ssh key checking.

import com.jcraft.jsch.*;

public class TestJSch {
    public static void main(String args[]) {
        JSch jsch = new JSch();
        Session session = null;
        try {
            session = jsch.getSession("username", "127.0.0.1", 22);
            session.setConfig("StrictHostKeyChecking", "no");
            session.setPassword("password");
            session.connect();

            Channel channel = session.openChannel("sftp");
            channel.connect();
            ChannelSftp sftpChannel = (ChannelSftp) channel;
            sftpChannel.get("remotefile.txt", "localfile.txt");
            sftpChannel.exit();
            session.disconnect();
        } catch (JSchException e) {
            e.printStackTrace();  
        } catch (SftpException e) {
            e.printStackTrace();
        }
    }
}

Here is an implementation of an explode function which is available in many other programming languages as a standard function:

type 
  TStringDynArray = array of String;

function Explode(const Separator, S: string; Limit: Integer = 0): TStringDynArray; 
var 
  SepLen: Integer; 
  F, P: PChar; 
  ALen, Index: Integer; 
begin 
  SetLength(Result, 0); 
  if (S = '') or (Limit < 0) then Exit; 
  if Separator = '' then 
  begin 
    SetLength(Result, 1); 
    Result[0] := S; 
    Exit; 
  end; 
  SepLen := Length(Separator); 
  ALen := Limit; 
  SetLength(Result, ALen); 

  Index := 0; 
  P := PChar(S); 
  while P^ <> #0 do 
  begin 
    F := P; 
    P := AnsiStrPos(P, PChar(Separator)); 
    if (P = nil) or ((Limit > 0) and (Index = Limit - 1)) then P := StrEnd(F); 
    if Index >= ALen then 
    begin 
      Inc(ALen, 5); 
      SetLength(Result, ALen); 
    end; 
    SetString(Result[Index], F, P - F); 
    Inc(Index); 
    if P^ <> #0 then Inc(P, SepLen); 
  end; 
  if Index < ALen then SetLength(Result, Index); 
end; 

Sample usage:

var
  res: TStringDynArray;
begin
  res := Explode(':', yourString);

As mentioned in numerous threads, the "standard" way of doing this is using setjmp/longjmp. I posted yet another such solution to https://github.com/psevon/exceptions-and-raii-in-c This is to my knowledge the only solution that relies on automatic cleanup of allocated resources. It implements unique and shared smartpointers, and allows intermediate functions to let exceptions pass through without catching and still have their locally allocated resources cleaned up properly.

These are all really good, written by academia and (some) are books (an unpublished oreilly book --translated from French, but no issues I've found), for example). I've *'d my favorite ones that helped me the most.

Try the inspect module. getmembers and the various tests should be helpful.

EDIT:

For example,

class MyClass(object):
    a = '12'
    b = '34'
    def myfunc(self):
        return self.a

>>> import inspect
>>> inspect.getmembers(MyClass, lambda a:not(inspect.isroutine(a)))
[('__class__', type),
 ('__dict__',
  <dictproxy {'__dict__': <attribute '__dict__' of 'MyClass' objects>,
   '__doc__': None,
   '__module__': '__main__',
   '__weakref__': <attribute '__weakref__' of 'MyClass' objects>,
   'a': '34',
   'b': '12',
   'myfunc': <function __main__.myfunc>}>),
 ('__doc__', None),
 ('__module__', '__main__'),
 ('__weakref__', <attribute '__weakref__' of 'MyClass' objects>),
 ('a', '34'),
 ('b', '12')]

Now, the special methods and attributes get on my nerves- those can be dealt with in a number of ways, the easiest of which is just to filter based on name.

>>> attributes = inspect.getmembers(MyClass, lambda a:not(inspect.isroutine(a)))
>>> [a for a in attributes if not(a[0].startswith('__') and a[0].endswith('__'))]
[('a', '34'), ('b', '12')]

...and the more complicated of which can include special attribute name checks or even metaclasses ;)

It is probably worth adding that an insert iterator of any kind (std::back_insert_iterator, std::front_insert_iterator, std::insert_iterator) is guaranteed to remain valid as long as all insertions are performed through this iterator and no other independent iterator-invalidating event occurs.

For example, when you are performing a series of insertion operations into a std::vector by using std::insert_iterator it is quite possible that these insertions will trigger vector reallocation, which will invalidate all iterators that "point" into that vector. However, the insert iterator in question is guaranteed to remain valid, i.e. you can safely continue the sequence of insertions. There's no need to worry about triggering vector reallocation at all.

This, again, applies only to insertions performed through the insert iterator itself. If iterator-invalidating event is triggered by some independent action on the container, then the insert iterator becomes invalidated as well in accordance with the general rules.

For example, this code

std::vector<int> v(10);
std::vector<int>::iterator it = v.begin() + 5;
std::insert_iterator<std::vector<int> > it_ins(v, it);

for (unsigned n = 20; n > 0; --n)
  *it_ins++ = rand();

is guaranteed to perform a valid sequence of insertions into the vector, even if the vector "decides" to reallocate somewhere in the middle of this process. Iterator it will obviously become invalid, but it_ins will continue to remain valid.

Pretty much all the answers currently add either leading spaces, trailing spaces or some other separator issue. To select from the fourth field where the separator is whitespace and the output separator is a single space using awk would be:

awk '{for(i=4;i<=NF;i++)printf "%s",$i (i==NF?ORS:OFS)}' file

To parametrize the starting field you could do:

awk '{for(i=n;i<=NF;i++)printf "%s",$i (i==NF?ORS:OFS)}' n=4 file

And also the ending field:

awk '{for(i=n;i<=m=(m>NF?NF:m);i++)printf "%s",$i (i==m?ORS:OFS)}' n=4 m=10 file

If you need it to work in IE7, you can't use the undocumented, buggy, and unsupported {'width':'auto'} option. Instead, add the following to your .dialog():

'open': function(){ $(this).dialog('option', 'width', this.scrollWidth) }

Whether .scrollWidth includes the right-side padding depends on the browser (Firefox differs from Chrome), so you can either add a subjective "good enough" number of pixels to .scrollWidth, or replace it with your own width-calculation function.

You might want to include width: 0 among your .dialog() options, since this method will never decrease the width, only increase it.

Tested to work in IE7, IE8, IE9, IE10, IE11, Firefox 30, Chrome 35, and Opera 22.

You can add a class to each of your .row divs to add some space in between them like so:

.spacer {
    margin-top: 40px; /* define margin as you see fit */
}

You can then use it like so:

<div class="row spacer">
   <div class="span4">...</div>
   <div class="span4">...</div>
   <div class="span4">...</div>
</div>

<div class="row spacer">
   <div class="span4">...</div>
   <div class="span4">...</div>
   <div class="span4">...</div>
</div>

compare() is equivalent to strcmp(). == is simple equality checking. compare() therefore returns an int, == is a boolean.

It means "not equal to" (as in, the values in cells E37-N37 are not equal to "", or in other words, they are not empty.)

For all built-in Python objects (like strings, lists, dicts, functions, etc.), if x is y, then x==y is also True.

Not always. NaN is a counterexample. But usually, identity (is) implies equality (==). The converse is not true: Two distinct objects can have the same value.

Also, is it generally considered better to just use '==' by default, even when comparing int or Boolean values?

You use == when comparing values and is when comparing identities.

When comparing ints (or immutable types in general), you pretty much always want the former. There's an optimization that allows small integers to be compared with is, but don't rely on it.

For boolean values, you shouldn't be doing comparisons at all. Instead of:

if x == True:
    # do something

write:

if x:
    # do something

For comparing against None, is None is preferred over == None.

I've always liked to use 'is' because I find it more aesthetically pleasing and pythonic (which is how I fell into this trap...), but I wonder if it's intended to just be reserved for when you care about finding two objects with the same id.

Yes, that's exactly what it's for.

For Java SE 5: According to Garbage Collector Ergonomics [Oracle]:

initial heap size:

Larger of 1/64th of the machine's physical memory on the machine or some reasonable minimum. Before J2SE 5.0, the default initial heap size was a reasonable minimum, which varies by platform. You can override this default using the -Xms command-line option.

maximum heap size:

Smaller of 1/4th of the physical memory or 1GB. Before J2SE 5.0, the default maximum heap size was 64MB. You can override this default using the -Xmx command-line option.

UPDATE:

As pointed out by Tom Anderson in his comment, the above is for server-class machines. From Ergonomics in the 5.0 JavaTM Virtual Machine:

In the J2SE platform version 5.0 a class of machine referred to as a server-class machine has been defined as a machine with

• 2 or more physical processors
• 2 or more Gbytes of physical memory

with the exception of 32 bit platforms running a version of the Windows operating system. On all other platforms the default values are the same as the default values for version 1.4.2.

In the J2SE platform version 1.4.2 by default the following selections were made

• initial heap size of 4 Mbyte
• maximum heap size of 64 Mbyte

Here is the simplest solution based on [https://en.wikipedia.org/wiki/Coefficient_of_determination]

# 1. 'Actual' and 'Predicted' data
df <- data.frame(
  y_actual = c(1:5),
  y_predicted  = c(0.8, 2.4, 2, 3, 4.8))

# 2. R2 Score components

# 2.1. Average of actual data
avr_y_actual <- mean(df$y_actual)

# 2.2. Total sum of squares
ss_total <- sum((df$y_actual - avr_y_actual)^2)

# 2.3. Regression sum of squares
ss_regression <- sum((df$y_predicted - avr_y_actual)^2)

# 2.4. Residual sum of squares
ss_residuals <- sum((df$y_actual - df$y_predicted)^2)

# 3. R2 Score
r2 <- 1 - ss_residuals / ss_total

join this "literal table",

select 
    t.c.value('@c', 'varchar(30)') code,
    t.c.value('@v', 'varchar(30)') val
from (select convert(xml, '<x c="CODE001" v="Value One" /><x c="CODE002" v="Value Two" />') aXmlCol) z
cross apply aXmlCol.nodes('/x') t(c)

Here's the ultimate shortest most responsible version that even works both AD and BC.

[drum rolls...]

<script>document.write(Date().split` `[3])</script>

That's it. 6 Bytes shorter than the accepted answer.

If you need to be ES5 compatible, you can settle for:

<script>document.write(Date().split(' ')[3])</script>

If these are just going to be textblocks (and thus one way binding), and you just want to concatenate values, just bind two textblocks and put them in a horizontal stackpanel.

    <StackPanel Orientation="Horizontal">
        <TextBlock Text="{Binding Name}"/>
        <TextBlock Text="{Binding ID}"/>
    </StackPanel>

That will display the text (which is all Textblocks do) without having to do any more coding. You might put a small margin on them to make them look right though.

All other answers must work, but using your same syntax (and understanding why the error)

SELECT * FROM MyParts LEFT JOIN MyPrice ON MyParts.Partid = MyPrice.Partid WHERE 
MyPart.PriceDate = (SELECT MAX(MyPrice2.PriceDate) FROM MyPrice as MyPrice2 
WHERE MyPrice2.Partid =  MyParts.Partid)

I was using Terminator before, so I found it convenient to re-map Alt + arrow-key to switch between the panes. This can be done in Preferences -> Keys -> Key Mappings - press the '+' button to add a mapping. Also, in my case such a mapping was already defined in Profiles, I simply removed it.

Use btn-primary-spacing class for all buttons remove margin-left class

Example :

<button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2 btn-primary-spacing">
  <span class="glyphicon glyphicon-plus" aria-hidden="true"></span> ADD PACKET
</button>

CSS will be like :

.btn-primary-spacing 
{
margin-right: 5px;
margin-bottom: 5px !important;
}

You can define a Root ng-App and in this ng-App you can define multiple nd-Controler. Like this

If you want to avoid encode html entities more than once

function encodeHTML(str){
    return str.replace(/([\u00A0-\u9999<>&])(.|$)/g, function(full, char, next) {
      if(char !== '&' || next !== '#'){
        if(/[\u00A0-\u9999<>&]/.test(next))
          next = '&#' + next.charCodeAt(0) + ';';

        return '&#' + char.charCodeAt(0) + ';' + next;
      }

      return full;
    });
}

function decodeHTML(str){
    return str.replace(/&#([0-9]+);/g, function(full, int) {
        return String.fromCharCode(parseInt(int));
    });
}

# Example

var text = "<a>Content &#169; <#>&<&#># </a>";

text = encodeHTML(text);
console.log("Encode 1 times: " + text);

// &#60;a&#62;Content &#169; &#60;#&#62;&#38;&#60;&#38;#&#62;# &#60;/a&#62;

text = encodeHTML(text);
console.log("Encode 2 times: " + text);

// &#60;a&#62;Content &#169; &#60;#&#62;&#38;&#60;&#38;#&#62;# &#60;/a&#62;

text = decodeHTML(text);
console.log("Decoded: " + text);

// <a>Content © <#>&<&#># </a>

As Shafik already wrote you need to use the right format because scanf gets you a char. Don't hesitate to look here if u aren't sure about the usage: http://www.cplusplus.com/reference/cstdio/printf/

Hint: It's faster/nicer to write x=x+1; the shorter way: x++;

Sorry for answering what's answered just wanted to give him the link - the site was really useful to me all the time dealing with C.

//div[@id='..' and @class='...]

should do the trick. That's selecting the div operators that have both attributes of the required value.

It's worth using one of the online XPath testbeds to try stuff out.

I had the same problem. I use Ubuntu 12.04. I tried disabling ipv6.

Modify the /etc/sysctl.conf and add the following:
#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Then restart the machine and check. I think this may be a ipv6 issue even in Windows OS.

Package Explorer / View Menu / Package Presentation... / Hierarchical

The "View Menu" can be opened with Ctrl + F10, or the small arrow-down icon in the top-right corner of the Package Explorer.

The connectivity: package does not guarantee the actual internet connection (could be just wifi connection without internet access).

Quote from the documentation:

Note that on Android, this does not guarantee connection to Internet. For instance, the app might have wifi access but it might be a VPN or a hotel WiFi with no access.

If you really need to check the connection to the www Internet the better choice would be

data_connection_checker package

Connections have a close method as specified in PEP-249 (Python Database API Specification v2.0):

import pyodbc
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest') 

csr = conn.cursor()  
csr.close()
conn.close()     #<--- Close the connection

Since the pyodbc connection and cursor are both context managers, nowadays it would be more convenient (and preferable) to write this as:

import pyodbc
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest') 
with conn:
    crs = conn.cursor()
    do_stuff
    # conn.commit() will automatically be called when Python leaves the outer `with` statement
    # Neither crs.close() nor conn.close() will be called upon leaving the `with` statement!! 

See https://github.com/mkleehammer/pyodbc/issues/43 for an explanation for why conn.close() is not called.

Note that unlike the original code, this causes conn.commit() to be called. Use the outer with statement to control when you want commit to be called.

Also note that regardless of whether or not you use the with statements, per the docs,

Connections are automatically closed when they are deleted (typically when they go out of scope) so you should not normally need to call [conn.close()], but you can explicitly close the connection if you wish.

and similarly for cursors (my emphasis):

Cursors are closed automatically when they are deleted (typically when they go out of scope), so calling [csr.close()] is not usually necessary.

If you convert table field:

1. Define the field so it contains seconds:

    CREATE TABLE IF NOT EXISTS test (
        ...
        field        INTERVAL SECOND(0)
    );
   

2. Extract the value. Remember to cast to int other wise you can get an unpleasant surprise once the intervals are big:

   EXTRACT(EPOCH FROM field)::int

I would like to make a addon for tiago's answer:

Suppose you're hiding element using ng-show and adding a required attribute on the same:

<div ng-show="false">
    <input required name="something" ng-model="name"/>
</div>

will throw an error something like :

An invalid form control with name='' is not focusable

This is because you just cannot impose required validation on hidden elements. Using ng-required makes it easier to conditionally apply required validation which is just awesome!!

You don't need to be echoing the info within the php file. A php include will automatically include any HTML within that file.

Make sure you're actually using a index file with a .php extension, .html won't work with php includes. (Unless you're telling your server to treat .html files otherwise)

Make sure your paths are correctly set up. From your description, the way you've set it up your header.php/navbar.php/image.php files should be in your root directory. So your root directory should look like this:

index.php
navbar.php
image.php
header.php

Otherwise if those PHP files are in a folder called /includes/, it should look like so:

<?php include ('includes/headings.php'); ?>

Your needs are covered by window.location('download.php');
But I think that you need to pass the file to be downloaded, not always download the same file, and that's why you are using a request, one option is to create a php file as simple as showfile.php and do a request like

var myfile = filetodownload.txt
var url = "shofile.php?file=" + myfile ;
ajaxRequest.open("GET", url, true);

showfile.php

<?php
$file = $_GET["file"] 
echo $file;

where file is the file name passed via Get or Post in the request and then catch the response in a function simply

if(ajaxRequest.readyState == 4){
                        var file = ajaxRequest.responseText;
                        window.location = 'downfile.php?file=' + file;  
                    }
                }

$attribute = Mage::getModel('eav/entity_attribute')
                ->loadByCode('catalog_product', 'manufacturer');

$valuesCollection = Mage::getResourceModel('eav/entity_attribute_option_collection')
            ->setAttributeFilter($attribute->getData('attribute_id'))
            ->setStoreFilter(0, false);

$preparedManufacturers = array();            
foreach($valuesCollection as $value) {
    $preparedManufacturers[$value->getOptionId()] = $value->getValue();
}   


if (count($preparedManufacturers)) {
    echo "<h2>Manufacturers</h2><ul>";
    foreach($preparedManufacturers as $optionId => $value) {
        $products = Mage::getModel('catalog/product')->getCollection();
        $products->addAttributeToSelect('manufacturer');
        $products->addFieldToFilter(array(
            array('attribute'=>'manufacturer', 'eq'=> $optionId,          
        ));

        echo "<li>" . $value . " - (" . $optionId . ") - (Products: ".count($products).")</li>";
    }
    echo "</ul>";
}

To plot text on a ggplot you use the geom_text. But I find it helpful to summarise the data first using ddply

dfl <- ddply(df, .(x), summarize, y=length(x))
str(dfl)

Since the data is pre-summarized, you need to remember to change add the stat="identity" parameter to geom_bar:

ggplot(dfl, aes(x, y=y, fill=x)) + geom_bar(stat="identity") +
    geom_text(aes(label=y), vjust=0) +
    opts(axis.text.x=theme_blank(),
        axis.ticks=theme_blank(),
        axis.title.x=theme_blank(),
        legend.title=theme_blank(),
        axis.title.y=theme_blank()
)

I'm not sure if you were after catalina.out or one of the other logs produced by Tomcat.

But, if you're after the catalina.out log file then follow the directions below:

• In the servers tab, double-click on the Tomcat Server. You will get a screen called Overview.

• Click on "Open launch configuration". Click on the "Common" tab.

• Towards the bottom of the screen you can check the "File" checkbox and then specify a file that can be used to log your console (catalina.out) output.

• Finally, restart the Tomcat server.

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

If you want to consider null values equality too, try the following

select column1, column2, 
   case
      when column1 is NULL and column2 is NULL then 'true'  
      when column1=column2 then 'true' 
      else 'false' 
   end 
from table;

You can find the ObjectId constructor on require('mongoose').Types. Here is an example:

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId();

id is a newly generated ObjectId.

You can read more about the Types object at Mongoose#Types documentation.

Ultimately, we are trying to get to this.

<div style="display: flex; justify-content: center;">
    <button ion-button>Login</button>
</div>

(Edited: wasn't aware of the `naked link' problem, sorry about that)

Taken from here:

string myString = "find Me and replace ME";
string strReplace = "me";
myString = Regex.Replace(myString, "me", strReplace, RegexOptions.IgnoreCase);

Seems you are not the first to complain of the lack of case insensitive string.Replace.

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

My problem is a bit different as I wanted to collect both stdout and stderr from a running process, but ultimately the same since I wanted to render the output in a widget as its generated.

I did not want to resort to many of the proposed workarounds using Queues or additional Threads as they should not be necessary to perform such a common task as running another script and collecting its output.

After reading the proposed solutions and python docs I resolved my issue with the implementation below. Yes it only works for POSIX as I'm using the select function call.

I agree that the docs are confusing and the implementation is awkward for such a common scripting task. I believe that older versions of python have different defaults for Popen and different explanations so that created a lot of confusion. This seems to work well for both Python 2.7.12 and 3.5.2.

The key was to set bufsize=1 for line buffering and then universal_newlines=True to process as a text file instead of a binary which seems to become the default when setting bufsize=1.

   def __init__(self, cmd):

ERROR, DEBUG and VERBOSE are simply macros that print output to the terminal.

This solution is IMHO 99.99% effective as it still uses the blocking readline function, so we assume the sub process is nice and outputs complete lines.

I welcome feedback to improve the solution as I am still new to Python.

you can search this file : resetroot.bat

just double click it so that your root accout will be reset and all the privileges are turned into YES

.indexOf() works well. If you want an example here is one:

  ArrayList<String> example = new ArrayList<String>();
  example.add("AB");
  example.add("CD");
  example.add("EF");
  example.add("GH");
  example.add("IJ");
  example.add("KL");
  example.add("MN");

  System.out.println("Index of 'AB': "+example.indexOf("AB"));
  System.out.println("Index of 'KL': "+example.indexOf("KL"));
  System.out.println("Index of 'AA': "+example.indexOf("AA"));
  System.out.println("Index of 'EF': "+example.indexOf("EF"));

will give you an output of

Index of 'AB': 0
Index of 'KL': 5
Index of 'AA': -1
Index of 'EF': 2

Note: This method returns -1 if the specified element is not present in the list.

@rahul-kumar 's solution works good for me, but i wanted to call my javascript function in my typescript

foo.myFunctions() // works in browser console, but foo can't be used in typescript file

I fixed it by declaring it in my typescript :

import { Component } from '@angular/core';
import { ScriptService } from './script.service';
declare var foo;

And now, i can call foo anywhere in my typecript file

You can also choose to break explicitly in code:

// Assuming C#
if (condition)
{
    System.Diagnostics.Debugger.Break();
}

From MSDN:

Debugger.Break: If no debugger is attached, users are asked if they want to attach a debugger. If yes, the debugger is started. If a debugger is attached, the debugger is signaled with a user breakpoint event, and the debugger suspends execution of the process just as if a debugger breakpoint had been hit.

This is only a fallback, though. Setting a conditional breakpoint in Visual Studio, as described in other comments, is a better choice.

See this:

In the Microsoft .NET framework, an assembly is a partially compiled code library for use in deployment, versioning and security

You need to instantiate an object in order to call its member functions. The member functions need an object to operate on; they can't just be used on their own. The main() function could, for example, look like this:

int main()
{
   Name_pairs np;
   cout << "Enter names and ages. Use 0 to cancel.\n";
   while(np.test())
   {
      np.read_names();
      np.read_ages();
   }
   np.print();
   keep_window_open();
}

That would be the tempfile module.

It has functions to get the temporary directory, and also has some shortcuts to create temporary files and directories in it, either named or unnamed.

Example:

import tempfile

print tempfile.gettempdir() # prints the current temporary directory

f = tempfile.TemporaryFile()
f.write('something on temporaryfile')
f.seek(0) # return to beginning of file
print f.read() # reads data back from the file
f.close() # temporary file is automatically deleted here

For completeness, here's how it searches for the temporary directory, according to the documentation:

1. The directory named by the TMPDIR environment variable.
2. The directory named by the TEMP environment variable.
3. The directory named by the TMP environment variable.
4. A platform-specific location:
   • On RiscOS, the directory named by the Wimp$ScrapDir environment variable.
   • On Windows, the directories C:\TEMP, C:\TMP, \TEMP, and \TMP, in that order.
   • On all other platforms, the directories /tmp, /var/tmp, and /usr/tmp, in that order.
5. As a last resort, the current working directory.

Use a dot or a pipe as the field separator:

awk -v FS='[.|]' '{
    printf "%s%s %s.%s\n", toupper(substr($4,1,1)), substr($4,2), $1, $2
}' << END
[email protected]|com.emailclient.account
[email protected]|com.socialsite.auth.account
END

gives:

Emailclient [email protected]
Socialsite [email protected]

here is the Sorting Simple Example try it

public class SortingSimpleExample {

    public static void main(String[] args) {
        int[] a={10,20,1,5,4,20,6,4,2,5,4,6,8,-5,-1};
              a=sort(a);
        for(int i:a)
              System.out.println(i);
}
    public static int[] sort(int[] a){

        for(int i=0;i<a.length;i++){
            for(int j=0;j<a.length;j++){
                int temp=0;
                if(a[i]<a[j]){
                    temp=a[j];                  
                    a[j]=a[i];                  
                    a[i]=temp;      
                  }         
                }
        }
        return a;

    }
}

You forgot the namespace you're referring to. Add

using namespace std;

to avoid std::string all the time.

I think this answer can also work (it may require a little bit of modification though) :

SELECT * FROM Students AS S1 WHERE EXISTS(SELECT Lastname, count(*) FROM Students AS S2 GROUP BY Lastname HAVING COUNT(*) > 3 WHERE S2.Lastname = S1.Lastname)

When binding the UI to your array you'll want to make sure you update that same array directly by setting the length to 0 and pushing the data into the array.

Instead of this (which set a different array reference to data which your UI won't know about):

 myService.async = function() {
    $http.get('test.json')
    .success(function (d) {
      data = d;
    });
  };

try this:

 myService.async = function() {
    $http.get('test.json')
    .success(function (d) {
      data.length = 0;
      for(var i = 0; i < d.length; i++){
        data.push(d[i]);
      }
    });
  };

Here is a fiddle that shows the difference between setting a new array vs emptying and adding to an existing one. I couldn't get your plnkr working but hopefully this works for you!

This works for me

var dataTable = $('#HelpdeskOverview').dataTable();

var oSettings = dataTable.fnSettings();
dataTable.fnClearTable(this);
for (var i=0; i<json.aaData.length; i++)
{
   dataTable.oApi._fnAddData(oSettings, json.aaData[i]);
}
oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
dataTable.fnDraw();

Another option is to use Homebrew which works on Linux and macOS to install just the supporting libraries:

brew install libpq

then

brew link libpq --force

(the --force option is required because it conflicts with the postgres formula.)

You could also use

ImageIcon background = new ImageIcon("Background/background.png");
JLabel label = new JLabel();
label.setBounds(0, 0, x, y);
label.setIcon(background);

JPanel panel = new JPanel();
panel.setLayout(null);
panel.add(label);

if your working with a absolut value as layout.

If you only want to return a blank when B2 is blank you can use an additional IF function for that scenario specifically, i.e.

=IF(B2="","",VLOOKUP(B2,Index!A1:B12,2,FALSE))

or to return a blank with any error from the VLOOKUP (e.g. including if B2 is populated but that value isn't found by the VLOOKUP) you can use IFERROR function if you have Excel 2007 or later, i.e.

=IFERROR(VLOOKUP(B2,Index!A1:B12,2,FALSE),"")

in earlier versions you need to repeat the VLOOKUP, e.g.

=IF(ISNA(VLOOKUP(B2,Index!A1:B12,2,FALSE)),"",VLOOKUP(B2,Index!A1:B12,2,FALSE))
