select sum(counts) from (
select count(1) as counts from foo 
union all
select count(1) as counts from bar)

that's the correct XOR swap algorithm

void xorSwap (int* x, int* y) {
   if (x != y) { //ensure that memory locations are different
      if (*x != *y) { //ensure that values are different
         *x ^= *y;
         *y ^= *x;
         *x ^= *y;
      }
   }
}

you have to ensure that memory locations are different and also that the actual values are different because A XOR A = 0

If you need pixel level control over canvas you can do using createImageData and putImageData.

HTML:

<canvas id="qrCode" width="200", height="200">
  QR Code
</canvas>

And JavaScript:

function setPixel(imageData, pixelData) {
  var index = (pixelData.x + pixelData.y * imageData.width) * 4;
    imageData.data[index+0] = pixelData.r;
    imageData.data[index+1] = pixelData.g;
    imageData.data[index+2] = pixelData.b;
    imageData.data[index+3] = pixelData.a;
}

element = document.getElementById("qrCode");
c = element.getContext("2d");

pixcelSize = 4;
width = element.width;
height = element.height;


imageData = c.createImageData(width, height);

for (i = 0; i < 1000; i++) {
  x = Math.random() * width / pixcelSize | 0; // |0 to Int32
  y = Math.random() * height / pixcelSize| 0;

  for(j=0;j < pixcelSize; j++){
    for(k=0;k < pixcelSize; k++){
     setPixel( imageData, {
         x: x * pixcelSize + j,  
         y: y * pixcelSize + k,
         r: 0 | 0,
         g: 0 | 0,
         b: 0 * 256 | 0,
         a: 255 // 255 opaque
       });
      }
  }
}

c.putImageData(imageData, 0, 0);

Working sample here

Use .val() instead of .innerHTML for getting value of selected option

Use .text() for getting text of selected option

Thanks for correcting :)

First you have to check if FileZilla is running on xampp control panel Than such error can occur You have to stop the FileZilla service from Xampp control panel

In the case of a dialog, it has a property called draggable, set it to false.

$("#yourDialog").dialog({
    draggable: false
});

Eventhough the question is old, i tried the proposed solution and it did not work for the dialog. Hope this may help others like me.

You can do this without moment.js

A way to do this in native Javascript code :

var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);

firstDay = moment(firstDay).format(yourFormat);
lastDay = moment(lastDay).format(yourFormat);

In some cases this also occurs if you have table hints and you have spaces between WITH clause and your hint, so best to type it like:

SELECT Column1 FROM Table1 t1 WITH(NOLOCK)
INNER JOIN Table2 t2 WITH(NOLOCK) ON t1.Column1 = t2.Column1

And not:

SELECT Column1 FROM Table1 t1 WITH (NOLOCK)
INNER JOIN Table2 t2 WITH (NOLOCK) ON t1.Column1 = t2.Column1

You're misunderstanding escaping.

The extra " characters are part of the string literal; they are interpreted by the compiler as a single ".

The actual value of your string is still He said to me , "Hello World".How are you ?, as you'll see if you print it at runtime.

Java

This should work:

// Gets linearlayout
LinearLayout layout = findViewById(R.id.numberPadLayout);
// Gets the layout params that will allow you to resize the layout
LayoutParams params = layout.getLayoutParams();
// Changes the height and width to the specified *pixels*
params.height = 100;
params.width = 100;
layout.setLayoutParams(params);

If you want to convert dip to pixels, use this:

int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, <HEIGHT>, getResources().getDisplayMetrics());

Kotlin

If it's just for display purposes, you can render the text as upper or lower case in pure CSS, without any Javascript using the text-transform property:

.myclass {
    text-transform: lowercase;
}

See https://developer.mozilla.org/en/CSS/text-transform for more info.

However, note that this doesn't actually change the value to lower case; it just displays it that way. This means that if you examine the contents of the element (ie using Javascript), it will still be in its original format.

In javascript use the preventDefault() method of the event args parameter.

<a href="no-script.html">Download now!</a>

$('a').click(function(e) {
    e.preventDefault(); // stop the browser from following
    window.location.href = 'downloads/file.pdf';
});

A stateful server keeps state between connections. A stateless server does not.

So, when you send a request to a stateful server, it may create some kind of connection object that tracks what information you request. When you send another request, that request operates on the state from the previous request. So you can send a request to "open" something. And then you can send a request to "close" it later. In-between the two requests, that thing is "open" on the server.

When you send a request to a stateless server, it does not create any objects that track information regarding your requests. If you "open" something on the server, the server retains no information at all that you have something open. A "close" operation would make no sense, since there would be nothing to close.

HTTP and NFS are stateless protocols. Each request stands on its own.

Sometimes cookies are used to add some state to a stateless protocol. In HTTP (web pages), the server sends you a cookie and then the browser holds the state, only to send it back to the server on a subsequent request.

SMB is a stateful protocol. A client can open a file on the server, and the server may deny other clients access to that file until the client closes it.

$(document).on('click', 'selector', handler);

Where click is an event name, and handler is an event handler, like reference to a function or anonymous function function() {}

PS: if you know the particular node you're adding dynamic elements to - you could specify it instead of document.

Use the recursive switch --recursive (-R)

svn revert -R .

Just remember that string comparison like "x" > "X" is case-sensitive

"aa" < "ab" //true
"aa" < "Ab" //false

You can use .toLowerCase() to compare without case sensitivity.

Misspellings are irritating, aren't they? Check your spelling of empty, but then also try this:

#!/bin/bash -e

if [ -s diff.txt ]
then
        rm -f empty.txt
        touch full.txt
else
        rm -f full.txt
        touch empty.txt
fi

I like shell scripting a lot, but one disadvantage of it is that the shell cannot help you when you misspell, whereas a compiler like your C++ compiler can help you.

Notice incidentally that I have swapped the roles of empty.txt and full.txt, as @Matthias suggests.

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

The only portable way to tail -f a file appears to be, in fact, to read from it and retry (after a sleep) if the read returns 0. The tail utilities on various platforms use platform-specific tricks (e.g. kqueue on BSD) to efficiently tail a file forever without needing sleep.

Therefore, implementing a good tail -f purely in Python is probably not a good idea, since you would have to use the least-common-denominator implementation (without resorting to platform-specific hacks). Using a simple subprocess to open tail -f and iterating through the lines in a separate thread, you can easily implement a non-blocking tail operation in Python.

Example implementation:

import threading, Queue, subprocess
tailq = Queue.Queue(maxsize=10) # buffer at most 100 lines

def tail_forever(fn):
    p = subprocess.Popen(["tail", "-f", fn], stdout=subprocess.PIPE)
    while 1:
        line = p.stdout.readline()
        tailq.put(line)
        if not line:
            break

threading.Thread(target=tail_forever, args=(fn,)).start()

print tailq.get() # blocks
print tailq.get_nowait() # throws Queue.Empty if there are no lines to read

Live Demo

Here is an actual implementation of what you described. I rewrote your code a bit using the latest best practices to actualize is. If you resize your browser windows under 1000px, the image's left and right side will be cropped using negative margins and it will be 300px narrower.

<style>
   .container {
      position: relative;
      width: 100%;
   }

   .bg {
      position:relative;
      z-index: 1;
      height: 100%;
      min-width: 1000px;
      max-width: 1500px;
      margin: 0 auto;
   }

   .nebula {
      width: 100%;
   }

   @media screen and (max-width: 1000px) {
      .nebula {
         width: 100%;
         overflow: hidden;
         margin: 0 -150px 0 -150px;
      }
   }
</style>

<div class="container">
   <div class="bg">
      <img src="http://i.stack.imgur.com/tFshX.jpg" class="nebula">
   </div>
</div>

You can try like this:-

if (string[0] == '\0') {
}

In your case it can be like:-

do {
   ...
} while (url[0] != '\0')

I had faced the similar error when supporting one application. It was about the generated classes for a SOAP Webservice.

The issue was caused due to the missing classes. When javax.xml.bind.Marshaller was trying to marshal the jaxb object it was not finding all dependent classes which were generated by using wsdl and xsd. after adding the jar with all the classes at the class path the issue was resolved.

cat /opt/gitlab/version-manifest.txt |grep gitlab-ce|awk '{print $2}'

ES6: In HTML, include the main JavaScript file using attribute type="module" (browser support):

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

And in the script.js file, include another file like this:

import { hello } from './module.js';
...
// alert(hello());

Inside the included file (module.js), you must export the function/class that you will import:

export function hello() {
    return "Hello World";
}

A working example is here. More information is here.

yeah I had the same question for a long time and I found the perfect one. here are some parameters from it.

https://maps.google.com?parameter = value

q=

is used to specify the search query in Google maps search.
eg :

https://maps.google.com?q=newyork or
https://maps.google.com?q=51.03841,-114.01679

near=

is used to specify the location alternative to q=. Also has the added effect of allowing you to increase the AddressDetails Accuracy value by being more precise. Mostly only useful if query is a business or suchlike.

z=

Zoom level. Can be set 19 normally, but in certain cases can go up to 23.

ll=

Latitude and longitude of the map centre point. Must be in that order. Requires decimal format. Interestingly, you can use this without q, in which case it doesn’t show a marker.

sll=

Similar to ll, only this sets the lat/long of the centre point for a business search. Requires the same input criteria as ll.

t=

Sets the kind of map shown. Can be set to:

m – normal  map,
k – satellite,
h – hybrid,
p – terrain

saddr=

Sets the starting point for directions searches. You can also add text into this in brackets to bold it in the directions sidebar.

daddr=

Sets the end point for directions searches, and again will bold any text added in brackets.You can also add "+to:" which will set via points. These can be added multiple times.

via=

Allows you to insert via points in directions. Must be in CSV format. For example, via=1,5 addresses 1 and 5 will be via points without entries in the sidebar. The start point (which is set as 0), and 2, 3 and 4 will all show full addresses.

doflg=

Changes the units used to measure distance (will default to the standard unit in country of origin). Change to ptk for metric or ptm for imperial.

msa=

Does stuff with My Maps. Set to 0 show defined My Maps, b to turn the My Maps sidebar on, 1 to show the My Maps tab on its own, or 2 to go to the new My Map creator form.

dirflg=

can set miscellaneous values below:

h - Avoid highway
t - Avoid tolls

In eclipse help documentation, we can all icons information as follows. Common path for all eclipse versions except eclipse version:

https://help.eclipse.org/2019-09/index.jsp?nav=%2F1

You could default the parameter to null or false.
This way, it would be shorter to test if a value has been passed as parameter.

@mixin clearfix($width: null) {

  @if not ($width) {

    // if width is not passed, or empty do this

  } @else {

    display: inline-block;
    width: $width;

  }
}

I imagine setting float:left for the dialog will work. Presumably the dialog is absolutely positioned by the plugin, in which case its position will be determined by this, but the side-effect of float - making elements only as wide as they need to be to hold content - will still take effect.

This should work if you just put a rule like

.myDialog {float:left}

in your stylesheet, though you may need to set it using jQuery

Same Problem I had... I was writing all the script in a seperate file and was adding it through tag into the end of the HTML file after body tag. After moving the the tag inside the body tag it works fine. before :

</body>
<script>require('../script/viewLog.js')</script>

after :

<script>require('../script/viewLog.js')</script>
</body>

You should set height of html, body, .wrapper to 100% (in order to inherit full height) and then just set a flex value greater than 1 to .row3 and not on the others.

.wrapper, html, body {
    height: 100%;
    margin: 0;
}
.wrapper {
    display: flex;
    flex-direction: column;
}
#row1 {
    background-color: red;
}
#row2 {
    background-color: blue;
}
#row3 {
    background-color: green;
    flex:2;
    display: flex;
}
#col1 {
    background-color: yellow;
    flex: 0 0 240px;
    min-height: 100%;/* chrome needed it a question time , not anymore */
}
#col2 {
    background-color: orange;
    flex: 1 1;
    min-height: 100%;/* chrome needed it a question time , not anymore */
}
#col3 {
    background-color: purple;
    flex: 0 0 240px;
    min-height: 100%;/* chrome needed it a question time , not anymore */
}

<div class="wrapper">
    <div id="row1">this is the header</div>
    <div id="row2">this is the second line</div>
    <div id="row3">
        <div id="col1">col1</div>
        <div id="col2">col2</div>
        <div id="col3">col3</div>
    </div>
</div>

DEMO

You can use the below for passing the raw text.

axios.post(
        baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan, 
        body, 
        {
            headers: { 
                'Authorization': 'Basic xxxxxxxxxxxxxxxxxxx',
                'Content-Type' : 'text/plain' 
            }
        }
).then(response => {
    this.setState({data:response.data});
    console.log(this.state.data);
});

Just have your raw text within body or pass it directly within quotes as 'raw text to be sent' in place of body.

The signature of the axios post is axios.post(url[, data[, config]]), so the data is where you pass your request body.

If you already have a full backup from your database, fortunately, you have an option in SQL Management Studio. In this case, you can use the following steps:

1. Right click on database -> Tasks -> Restore -> Database.

2. In General tab, click on Timeline -> select Specific date and time option.

3. Move the timeline slider to before update command time -> click OK.

4. In the destination database name, type a new name.

5. In the Files tab, check in Reallocate all files to folder and then select a new path to save your recovered database.

6. In the options tab, check in Overwrite ... and remove Take tail-log... check option.

7. Finally, click on OK and wait until the recovery process is over.

I have used this method myself in an operational database and it was very useful.

Change your div into a flex container:

div { display:flex; }

Now there are two methods to center the alignments for all the content:

Method 1:

div { align-items:center; }

DEMO

Method 2:

div * { margin-top:auto; margin-bottom:auto; }

DEMO

Try different width and height values on the img and different font size values on the span and you'll see they always remain in the middle of the container.

I'm using the following function for that; it's an adaptation from one of the man entries in the fputscsv comments. And you'll probably want to flatten that array; not sure what happens if you pass in a multi-dimensional one.

/**
  * Formats a line (passed as a fields  array) as CSV and returns the CSV as a string.
  * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120
  */
function arrayToCsv( array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = array();
    foreach ( $fields as $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output[] = 'NULL';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
        }
        else {
            $output[] = $field;
        }
    }

    return implode( $delimiter, $output );
}

It seems like there is a lot of incorrect information about the ValidationSettings:UnobtrusiveValidationMode value. To Disable it you need to do the following.

<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />

The word None, not WebForms should be used to disable this feature.

In typescript you can do the following to suppress the error:

let subString?: string;

subString > !null; - Note the added exclamation mark before null.

If you are using Asp.Identity UseManager, it automatically sets the value of

RequestContext.Principal.Identity.GetUserId()

based on IdentityUser you use in creating the IdentityDbContext.

If ever you are implementing a custom user table and owin token bearer authentication, kindly check on my answer.

How to get user context during Web Api calls?

Hope it still helps. :)

Use regular expression no need to convert it to char array

if(Regex.IsMatch("yourString",".*?[a-zA-Z].*?"))
{
errorCounter++;
}

There is a simpler way in Android

 DateFormat.getInstance().format(currentTimeMillis);

Moreover, Date is deprecated, so use DateFormat class.

   DateFormat.getDateInstance().format(new Date(0));  
   DateFormat.getDateTimeInstance().format(new Date(0));  
   DateFormat.getTimeInstance().format(new Date(0));  

The above three lines will give:

Dec 31, 1969  
Dec 31, 1969 4:00:00 PM  
4:00:00 PM  12:00:00 AM

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

$("#myDiv").hide();

will set the css display to none. if you need to set visibility to hidden as well, could do this via

$("#myDiv").css("visibility", "hidden");

or combine both in a chain

$("#myDiv").hide().css("visibility", "hidden");

or write everything with one css() function

$("#myDiv").css({
  display: "none",
  visibility: "hidden"
});

$(document).ready(function(){
    $('img').each(function(){
        var maxWidth = 660;
        var ratio = 0;
        var img = $(this);

        if(img.width() > maxWidth){
            ratio = img.height() / img.width();
            img.attr('width', maxWidth);
            img.attr('height', (maxWidth*ratio));   
        }
    });
});

that will do the magic trick for everyone using latest jquery. Be sure you set your selector right (I used $('img') but that can be different in your case). This only works for landscape mode. But if you look at it, only a few things have to be done to set it to portrait, aka, if img.height() > maxHeight) stuff

It doesn't. Somewhere in your print stylesheet, you must have this section of code:

a[href]::after {
    content: " (" attr(href) ")"
}

The only other possibility is you have an extension doing it for you.

Accepted answer didn't work for me, this does:

What's the difference between an RDD's map and mapPartitions method?

The method map converts each element of the source RDD into a single element of the result RDD by applying a function. mapPartitions converts each partition of the source RDD into multiple elements of the result (possibly none).

And does flatMap behave like map or like mapPartitions?

Neither, flatMap works on a single element (as map) and produces multiple elements of the result (as mapPartitions).

I love doing du -sh * | sort -nr | less to sort by the largest files first

Define this in your xml code

android:inputType="number"

You can use a WScript object and call the Sleep method on it:

Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds

Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000

You are passing the Application Context not the Activity Context with

getApplicationContext();

Wherever you are passing it pass this or ActivityName.this instead.

Since you are trying to cast the Context you pass (Application not Activity as you thought) to an Activity with

(Activity)

you get this exception because you can't cast the Application to Activity since Application is not a sub-class of Activity.

You can try this it will help for you.You can't get path from WhatsApp directly.If you need an file path first copy file and send new file path. Using the code below

 public static String getFilePathFromURI(Context context, Uri contentUri) {
    String fileName = getFileName(contentUri);
    if (!TextUtils.isEmpty(fileName)) {
        File copyFile = new File(TEMP_DIR_PATH  + fileName+".jpg");
        copy(context, contentUri, copyFile);
        return copyFile.getAbsolutePath();
    }
    return null;
}

public static String getFileName(Uri uri) {
    if (uri == null) return null;
    String fileName = null;
    String path = uri.getPath();
    int cut = path.lastIndexOf('/');
    if (cut != -1) {
        fileName = path.substring(cut + 1);
    }
    return fileName;
}

public static void copy(Context context, Uri srcUri, File dstFile) {
    try {
        InputStream inputStream = context.getContentResolver().openInputStream(srcUri);
        if (inputStream == null) return;
        OutputStream outputStream = new FileOutputStream(dstFile);
        IOUtils.copy(inputStream, outputStream);
        inputStream.close();
        outputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Then IOUtils class is like below

public class IOUtils {



private static final int BUFFER_SIZE = 1024 * 2;

private IOUtils() {
    // Utility class.
}

public static int copy(InputStream input, OutputStream output) throws Exception, IOException {
    byte[] buffer = new byte[BUFFER_SIZE];

    BufferedInputStream in = new BufferedInputStream(input, BUFFER_SIZE);
    BufferedOutputStream out = new BufferedOutputStream(output, BUFFER_SIZE);
    int count = 0, n = 0;
    try {
        while ((n = in.read(buffer, 0, BUFFER_SIZE)) != -1) {
            out.write(buffer, 0, n);
            count += n;
        }
        out.flush();
    } finally {
        try {
            out.close();
        } catch (IOException e) {
            Log.e(e.getMessage(), e.toString());
        }
        try {
            in.close();
        } catch (IOException e) {
            Log.e(e.getMessage(), e.toString());
        }
    }
    return count;
}


}

You actually want to do

import os
os.environ["MY_DATA"] = "my_export"

The edit you posted was valid for an older version of React-router (v0.13) and doesn't work anymore.

React Router v1, v2 and v3

Since version 1.0.0 you define optional parameters with:

<Route path="to/page(/:pathParam)" component={MyPage} />

and for multiple optional parameters:

<Route path="to/page(/:pathParam1)(/:pathParam2)" component={MyPage} />

You use parenthesis ( ) to wrap the optional parts of route, including the leading slash (/). Check out the Route Matching Guide page of the official documentation.

Note: The :paramName parameter matches a URL segment up to the next /, ?, or #. For more about paths and params specifically, read more here.

React Router v4 and above

React Router v4 is fundamentally different than v1-v3, and optional path parameters aren't explicitly defined in the official documentation either.

Instead, you are instructed to define a path parameter that path-to-regexp understands. This allows for much greater flexibility in defining your paths, such as repeating patterns, wildcards, etc. So to define a parameter as optional you add a trailing question-mark (?).

As such, to define an optional parameter, you do:

<Route path="/to/page/:pathParam?" component={MyPage} />

and for multiple optional parameters:

<Route path="/to/page/:pathParam1?/:pathParam2?" component={MyPage} />

Note: React Router v4 is incompatible with react-router-relay (read more here). Use version v3 or earlier (v2 recommended) instead.

Use Callable instead of Thread, then you can call Future#get() which throws any exception that the Callable threw.

I think the best answer is

int words = 0;
int lines = 0;
int chars = 0;
while(in.hasNextLine())  {
    lines++;
    String line = in.nextLine();
   for(int i=0;i<line.length();i++)
    {
        if(line.charAt(i)!=' ' && line.charAt(i)!='\n')
        chars ++;
    }
    words += new StringTokenizer(line, " ,").countTokens();
}

i had to change my form's POST to a GET. i was just doing a demo post to an html page, on a test azure site. read this for info: http://support.microsoft.com/kb/942051

I simply went to my Android resources folder on my C:/ drive (C:/Android), deleted the 'eclipse' folder and all its contents. I downloaded Android Developer Tools once more and just moved over the 'eclipse' folder.

I started up and everything was fine; I had updated to version 23.

Hopefully this helps, possibly not suitable for everyone as some of you have Eclipse modifications but for someone who, like me, wanted a quick fix and get back to developing this seemed to be the easiest path.

You cannot execute Pipeline script locally, since its whole purpose is to script Jenkins. (Which is one reason why it is best to keep your Jenkinsfile short and limited to code which actually deals with Jenkins features; your actual build logic should be handled with external processes or build tools which you invoke via a one-line sh or bat step.)

If you want to test a change to Jenkinsfile live but without committing it, use the Replay feature added in 1.14

JENKINS-33925 tracks the desired for an automated test framework.

In bootstrap you can use .text-centerto align center. also add .row and .col-md-* to your code.

align= is deprecated,

Added .col-xs-* for demo

UPDATE(OCT 2017)

For those who are reading this and want to use the new version of bootstrap (beta version), you can do the above in a simpler way, using Boostrap Flexbox utilities classes

alert($("#form_id").serialize());

This isn't my answer, but it definitely resonates with me. It's from ThoughtWorks' Technology Radar from October 2012:

Two things have caused fatigue with XML-based build tools like Ant and Maven: too many angry pointy braces and the coarseness of plug-in architectures. While syntax issues can be dealt with through generation, plug-in architectures severely limit the ability for build tools to grow gracefully as projects become more complex. We have come to feel that plug-ins are the wrong level of abstraction, and prefer language-based tools like Gradle and Rake instead, because they offer finer-grained abstractions and more flexibility long term.

They are lists because you type them as lists in the dictionary:

bikes = {
    # Bike designed for children"
    "Trike": ["Trike", 20, 100],
    # Bike designed for everyone"
    "Kruzer": ["Kruzer", 50, 165]
    }

You should use the bike-class instead:

bikes = {
    # Bike designed for children"
    "Trike": Bike("Trike", 20, 100),
    # Bike designed for everyone"
    "Kruzer": Bike("Kruzer", 50, 165)
    }

This will allow you to get the cost of the bikes with bike.cost as you were trying to.

for bike in bikes.values():
    profit = bike.cost * margin
    print(bike.name + " : " + str(profit))

This will now print:

Kruzer : 33.0
Trike : 20.0

You can simply make the start_date required using

<input type="submit" value="Submit" required />

You don't even need the checkform() then.

Thanks

To avoid string concatenation you can use jQuery.grep

$($.grep($("#edit-field-service-sub-cat-value option"),
         function(n,i){
           return n.value==title;
         })
 ).hide()

SUM is used to sum the value in a column for multiple rows. You can just add your columns together:

select tblExportVertexCompliance.TotalDaysOnIncivek + tblExportVertexCompliance.IncivekDaysOtherSource AS [Total Days on Incivek]

It's possible but no heap allocation allowed directly. Heap allocation is performed at runtime. Here are a few examples:

static SOME_INT: i32 = 5;
static SOME_STR: &'static str = "A static string";
static SOME_STRUCT: MyStruct = MyStruct {
    number: 10,
    string: "Some string",
};
static mut db: Option<sqlite::Connection> = None;

fn main() {
    println!("{}", SOME_INT);
    println!("{}", SOME_STR);
    println!("{}", SOME_STRUCT.number);
    println!("{}", SOME_STRUCT.string);

    unsafe {
        db = Some(open_database());
    }
}

struct MyStruct {
    number: i32,
    string: &'static str,
}

You might want to remove the accents and diacritic signs first, then on each character position check if the "simplified" string is an ascii letter - if it is, the original position shall contain word characters, if not, it can be removed.

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

Towards an efficient algorithm for pairing socks from a pile

Preconditions

1. There must be at least one sock in the pile
2. The table must be large enough to accommodate N/2 socks (worst case), where N is the total number of socks.

Algorithm

Try:

1. Pick the first sock
2. Put it down on the table
3. Pick next sock, and look at it (may throw 'no more socks in the pile' exception)
4. Now scan the socks on the table (throws exception if there are no socks left on the table)
5. Is there any match? a) yes => remove the matching sock from the table b) no => put the sock on the table (may throw 'the table is not large enough' exception)

Except:

• The table is not large enough:
     carefully mix all unpaired socks together, then resume operation
     // this operation will result in a new pile and an empty table

• No socks left on the table:
     throw (the last unpairable sock)

• No socks left in the pile:
     exit laundry room

Finally:

• If there are still socks in the pile:
     goto 3

Known issues

The algorithm will enter an infinite loop if there is no table around or there is not enough place on the table to accommodate at least one sock.

Possible improvement

Depending on the number of socks to be sorted, throughput could be increased by sorting the socks on the table, provided there's enough space.

In order for this to work, an attribute is needed that has a unique value for each pair of socks. Such an attribute can be easily synthesized from the visual properties of the socks.

Sort the socks on the table by said attribute. Let's call that attribute ' colour'. Arrange the socks in a row, and put darker coloured socks to the right (i.e. .push_back()) and lighter coloured socks to the left (i.e. .push_front())

For huge piles and especially previously unseen socks, attribute synthesis might require significant time, so throughput will apparently decrease. However, these attributes can be persisted in memory and reused.

Some research is needed to evaluate the efficiency of this possible improvement. The following questions arise:

• What is the optimal number of socks to be paired using above improvement?
• For a given number of socks, how many iterations are needed before throughput increases?
  a) for the last iteration
  b) for all iterations overall

PoC in line with the MCVE guidelines:

#include <iostream>
#include <vector>
#include <string>
#include <time.h>

using namespace std;

struct pileOfsocks {
    pileOfsocks(int pairCount = 42) :
        elemCount(pairCount<<1) {
        srand(time(NULL));
        socks.resize(elemCount);

        vector<int> used_colors;
        vector<int> used_indices;

        auto getOne = [](vector<int>& v, int c) {
            int r;
            do {
                r = rand() % c;
            } while (find(v.begin(), v.end(), r) != v.end());
            v.push_back(r);
            return r;
        };

        for (auto i = 0; i < pairCount; i++) {
            auto sock_color = getOne(used_colors, INT_MAX);
            socks[getOne(used_indices, elemCount)] = sock_color;
            socks[getOne(used_indices, elemCount)] = sock_color;
        }
    }

    void show(const string& prompt) {
        cout << prompt << ":" << endl;
        for (auto i = 0; i < socks.size(); i++){
            cout << socks[i] << " ";
        }
        cout << endl;
    }

    void pair() {
        for (auto i = 0; i < socks.size(); i++) {
            std::vector<int>::iterator it = find(unpaired_socks.begin(), unpaired_socks.end(), socks[i]);
            if (it != unpaired_socks.end()) {
                unpaired_socks.erase(it);
                paired_socks.push_back(socks[i]);
                paired_socks.push_back(socks[i]);
            }
            else
                unpaired_socks.push_back(socks[i]);
        }

        socks = paired_socks;
        paired_socks.clear();
    }

private:
    int elemCount;
    vector<int> socks;
    vector<int> unpaired_socks;
    vector<int> paired_socks;
};

int main() {
    pileOfsocks socks;

    socks.show("unpaired socks");
    socks.pair();
    socks.show("paired socks");

    system("pause");
    return 0;
}

I had this problem and it was because the panel was outside of the [data-role="page"] element.

1. To me the best answer to the question what is a DTO is that DTO's are simple objects that should not contain any business logic or methods implementation that would require testing.
2. Normally your model (using the MVC pattern) are intelligent models, and they can contain a lot of/some methods that do some different operations for that model specifically (not business logic, this should be at the controllers). However, when you transfer data (eg. calling a REST (GET/POST/whatever) endpoint from somewhere, or consuming a webservice using SOA, etc...) you do not want to transmit the big sized object with code that is not necessary for the endpoint, will consume data, and slow down the transfer.

I saw this method on youtube hence posting here.

There are (more than) three popular ways to use MySQL from PHP. This outlines some features/differences PHP: Choosing an API:

1. (DEPRECATED) The mysql functions are procedural and use manual escaping.
2. MySQLi is a replacement for the mysql functions, with object-oriented and procedural versions. It has support for prepared statements.
3. PDO (PHP Data Objects) is a general database abstraction layer with support for MySQL among many other databases. It provides prepared statements, and significant flexibility in how data is returned.

I would recommend using PDO with prepared statements. It is a well-designed API and will let you more easily move to another database (including any that supports ODBC) if necessary.

In a single line it would be:

(new Form2()).Show();

Hope it helps.

Just to be complete, I'll build build off of Robocide and point out that typeid can be used alone without using name():

#include <typeinfo>
#include <iostream>

using namespace std;

class A {
public:
    virtual ~A() = default; // We're not polymorphic unless we
                            // have a virtual function.
};
class B : public A { } ;
class C : public A { } ;

int
main(int argc, char* argv[])
{
    B b;
    A& a = b;

    cout << "a is B: " << boolalpha << (typeid(a) == typeid(B)) << endl;
    cout << "a is C: " << boolalpha << (typeid(a) == typeid(C)) << endl;
    cout << "b is B: " << boolalpha << (typeid(b) == typeid(B)) << endl;
    cout << "b is A: " << boolalpha << (typeid(b) == typeid(A)) << endl;
    cout << "b is C: " << boolalpha << (typeid(b) == typeid(C)) << endl;
}

Output:

a is B: true
a is C: false
b is B: true
b is A: false
b is C: false

I had faced the same issue because of some dll files were missing from References of VS13. I went to the location http://scn.sap.com/docs/DOC-7824 and installed the newest pack. It resolved the issue.

On CentOS 6.5, the following worked for me:

sudo yum install -y nodejs

You can save object in preferences without using any library, first of all your object class must implement Serializable:

public class callModel implements Serializable {

private long pointTime;
private boolean callisConnected;

public callModel(boolean callisConnected,  long pointTime) {
    this.callisConnected = callisConnected;
    this.pointTime = pointTime;
}
public boolean isCallisConnected() {
    return callisConnected;
}
public long getPointTime() {
    return pointTime;
}

}

Then you can easily use these two method to convert object to string and string to object:

 public static <T extends Serializable> T stringToObjectS(String string) {
    byte[] bytes = Base64.decode(string, 0);
    T object = null;
    try {
        ObjectInputStream objectInputStream = new ObjectInputStream(new ByteArrayInputStream(bytes));
        object = (T) objectInputStream.readObject();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return object;
}

 public static String objectToString(Parcelable object) {
    String encoded = null;
    try {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
        objectOutputStream.writeObject(object);
        objectOutputStream.close();
        encoded = new String(Base64.encodeToString(byteArrayOutputStream.toByteArray(), 0));
    } catch (IOException e) {
        e.printStackTrace();
    }
    return encoded;
}

To save:

SharedPreferences  mPrefs = getPreferences(MODE_PRIVATE);
Editor prefsEditor = mPrefs.edit();
prefsEditor.putString("MyObject", objectToString(callModelObject));
prefsEditor.commit();

To read

String value= mPrefs.getString("MyObject", "");
MyObject obj = stringToObjectS(value);

1. Set the height of your label to the same height as the multiline textbox.

2. Add the cssClass .alignTop{vertical-align: middle;} for the label control.

   <p>
       <asp:Label ID="DescriptionLabel" runat="server" Text="Description: " Width="70px" Height="200px" CssClass="alignTop"></asp:Label>
       <asp:Textbox id="DescriptionTextbox" runat="server" Width="400px" Height="200px" TextMode="MultiLine"></asp:Textbox>
       <asp:RequiredFieldValidator id="DescriptionRequiredFieldValidator" runat="server" ForeColor="Red"
       ControlToValidate="DescriptionTextbox" ErrorMessage="Description is a required field.">    
   </asp:RequiredFieldValidator>
   

I believe it's most commonly called the "splat operator." Unpacking arguments is what it does.

You could parse the JSON to an object, then create your malformed JSON from the ajavscript object. This may not be the best performance-wise, tho.

Otherwise, if you only need to make very small changes to the string, just treat it as a string, and mangle it using standard javascript.

I came up against this problem too, and in trying to solve it I kept crashing the chrome tab that was running my app. It looks like the spread operator for objects was the culprit.

With a little help from adrianolsk’s comment and sidonaldson's answer above, I used Object.assign() the output of the spread operator from babel, like so:

this.options.map(option => {
  // New properties to be added
  const newPropsObj = {
    newkey1:value1,
    newkey2:value2
  };

  // Assign new properties and return
  return Object.assign(option, newPropsObj);
});

There is a std::swap in <algorithm>

You could always add an extra parameter to the constructor called something like mode and then perform a switch statement on it...

class myClass 
{
    var $error ;
    function __construct ( $data, $mode )
    {
        $this->error = false
        switch ( $mode )
        {
            'id' : processId ( $data ) ; break ;
            'row' : processRow ( $data ); break ;
            default : $this->error = true ; break ;
         }
     }

     function processId ( $data ) { /* code */ }
     function processRow ( $data ) { /* code */ }
}

$a = new myClass ( $data, 'id' ) ;
$b = new myClass ( $data, 'row' ) ;
$c = new myClass ( $data, 'something' ) ;

if ( $a->error )
   exit ( 'invalid mode' ) ;
if ( $b->error )
   exit ('invalid mode' ) ;
if ( $c->error )
   exit ('invalid mode' ) ;

Also with that method at any time if you wanted to add more functionality you can just add another case to the switch statement, and you can also check to make sure someone has sent the right thing through - in the above example all the data is ok except for C as that is set to "something" and so the error flag in the class is set and control is returned back to the main program for it to decide what to do next (in the example I just told it to exit with an error message "invalid mode" - but alternatively you could loop it back round until valid data is found).

Well looks like if you copy paste the repository link you end up with this issue.

What I have noticed it this

1. If you use the copy button on GitHub and then paste the URL in GitBash(Windows) it throws this error
2. If you select the link and then paste then it works, or you could also just type the URL that works as well.

So I think it might be an issue with the GitHub copy button

[self.tableView setTableFooterView:footerView];

The error message is saying that there's already a record with null as the email. In other words, you already have a user without an email address.

The relevant documentation for this:

If a document does not have a value for the indexed field in a unique index, the index will store a null value for this document. Because of the unique constraint, MongoDB will only permit one document that lacks the indexed field. If there is more than one document without a value for the indexed field or is missing the indexed field, the index build will fail with a duplicate key error.

You can combine the unique constraint with the sparse index to filter these null values from the unique index and avoid the error.

unique indexes

Sparse indexes only contain entries for documents that have the indexed field, even if the index field contains a null value.

In other words, a sparse index is ok with multiple documents all having null values.

sparse indexes

Your error says that the key is named mydb.users.$email_1 which makes me suspect that you have an index on both users.email and users.local.email (The former being old and unused at the moment). Removing a field from a Mongoose model doesn't affect the database. Check with mydb.users.getIndexes() if this is the case and manually remove the unwanted index with mydb.users.dropIndex(<name>).

i tried the last answer from Sandeep Kumar, and i found way more simple :

<option value="1" <c:if test="${item.key == 1}"> selected </c:if>>

The extra [ ] on the outside of your second syntax are unnecessary, and possibly confusing. You may use them, but if you must you need to have whitespace between them.

Alternatively:

while [ $stats -gt 300 ] || [ $stats -eq 0 ]

You can index into a string in C# like an array, and you get the character at that index.

Example:

In Java, you would say

str.charAt(8);

In C#, you would say

str[8];

The other answers address the main thrust of the question, but just to comment on this part...

PS C:\> [array]$foo = @("bar")
PS C:\> $foo -eq $null
PS C:\>

How can "-eq $null" give no results? It's either $null or it's not.

It's confusing at first, but that is giving you the result of $foo -eq $null, it's just that the result has no displayable representation.

Since $foo holds an array, $foo -eq $null means "return an array containing the elements of $foo that are equal to $null". Are there any elements of $foo that are equal to $null? No, so $foo -eq $null should return an empty array. That's exactly what it does, the problem is that when an empty array is displayed at the console you see...nothing...

PS> @()
PS> 

The array is still there, even if you can't see its elements...

PS> @().GetType()

IsPublic IsSerial Name                                     BaseType

PS> @().Length
0

We can use similar commands to confirm that $foo -eq $null is returning an array that we're not able to "see"...

PS> $foo -eq $null
PS> ($foo -eq $null).GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Object[]                                 System.Array


PS> ($foo -eq $null).Length
0
PS> ($foo -eq $null).GetValue(0)
Exception calling "GetValue" with "1" argument(s): "Index was outside the bounds of the array."
At line:1 char:1
+ ($foo -eq $null).GetValue(0)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : IndexOutOfRangeException

Note that I am calling the Array.GetValue method instead of using the indexer (i.e. ($foo -eq $null)[0]) because the latter returns $null for invalid indices and there's no way to distinguish them from a valid index that happens to contain $null.

We see similar behavior if we test for $null in/against an array that contains $null elements...

PS> $bar = @($null)
PS> $bar -eq $null
PS> ($bar -eq $null).GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Object[]                                 System.Array


PS> ($bar -eq $null).Length
1
PS> ($bar -eq $null).GetValue(0)
PS> $null -eq ($bar -eq $null).GetValue(0)
True
PS> ($bar -eq $null).GetValue(0) -eq $null
True
PS> ($bar -eq $null).GetValue(1)
Exception calling "GetValue" with "1" argument(s): "Index was outside the bounds of the array."
At line:1 char:1
+ ($bar -eq $null).GetValue(1)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : IndexOutOfRangeException

In this case, $bar -eq $null returns an array containing one element, $null, which has no visual representation at the console...

PS> @($null)
PS> @($null).GetType()

IsPublic IsSerial Name                                     BaseType

You can do as

 body{
        background:url('equote.png'),url('equote.png');
        background-size:400px 100px,50px 50px;
    }

foreach my $key (keys %$ad_grp_ref) {
    ...
}

Perl::Critic and daxim recommend the style

foreach my $key (keys %{ $ad_grp_ref }) {
    ...
}

out of concerns for readability and maintenance (so that you don't need to think hard about what to change when you need to use %{ $ad_grp_obj[3]->get_ref() } instead of %{ $ad_grp_ref })

Don't quote the column filename

mysql> INSERT INTO risks (status, subject, reference_id, location, category, team,    technology, owner, manager, assessment, notes,filename) 
VALUES ('san', 'ss', 1, 1, 1, 1, 2, 1, 1, 'sment', 'notes','santu');

You can convert both the values to lower case and compare.

Here is an example:

If LCase(Range("J6").Value) = LCase("Tawi") Then
   Range("J6").Value = "Tawi-Tawi"
End If

If you want to have your vars in files under group_vars, just move them here. Vars can be in the inventory ([group:vars] section) but also (and foremost) in files under group_vars or hosts_vars.

For instance, with your example above, you can move your vars for group tests in the file group_vars/tests :

Inventory file :

[lb]
10.112.84.122

[tomcat]
10.112.84.124

[jboss5]
10.112.84.122

...

[tests:children]
lb
tomcat
jboss5

[default:children]
tests

group_vars/tests file :

data_base_user=NETWIN-4.3
data_base_password=NETWIN
data_base_encrypted_password=
data_base_host=10.112.69.48
data_base_port=1521
data_base_service=ssdenwdb
data_base_url=jdbc:oracle:thin:@10.112.69.48:1521/ssdenwdb

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

You can also use Eclipse's keyboard shortcuts: just go on preferences > keymap and choose Eclipse from the drop-down menu. And all your Eclipse shortcuts will be used in here.

Please find in the below code which escapes the single quotes as part of the entered string using a regular expression. It validates if the user-entered string is comma-separated and at the same time it even escapes any single quote(s) entered as part of the string.

In order to escape single quotes, just enter a backward slash followed by a single quote like: \’ as part of the string. I used jQuery validator for this example, and you can use as per your convenience.

Valid String Examples:

'Hello'

'Hello', 'World'

'Hello','World'

'Hello','World',' '

'It\'s my world', 'Can\'t enjoy this without me.', 'Welcome, Guest'

HTML:

<tr>
    <td>
        <label class="control-label">
            String Field:
        </label>
        <div class="inner-addon right-addon">
            <input type="text" id="stringField"
                   name="stringField"
                   class="form-control"
                   autocomplete="off"
                   data-rule-required="true"
                   data-msg-required="Cannot be blank."
                   data-rule-commaSeparatedText="true"
                   data-msg-commaSeparatedText="Invalid comma separated value(s).">
        </div>
    </td>

JavaScript:

     /**
 *
 * @param {type} param1
 * @param {type} param2
 * @param {type} param3
 */
jQuery.validator.addMethod('commaSeparatedText', function(value, element) {

    if (value.length === 0) {
        return true;
    }
    var expression = new RegExp("^((')([^\'\\\\]*(?:\\\\.[^\'\\\\])*)[\\w\\s,\\.\\-_\\[\\]\\)\\(]+([^\'\\\\]*(?:\\\\.[^\'\\\\])*)('))(((,)|(,\\s))(')([^\'\\\\]*(?:\\\\.[^\'\\\\])*)[\\w\\s,\\.\\-_\\[\\]\\)\\(]+([^\'\\\\]*(?:\\\\.[^\'\\\\])*)('))*$");
    return expression.test(value);
}, 'Invalid comma separated string values.');

if all you're trying to do is get the value of a single entry in a map, there's no need to loop over any collection at all. simplifying gautum's response slightly, you can get the value of a named map entry as follows:

<c:out value="${map['key']}"/>

where 'map' is the collection and 'key' is the string key for which you're trying to extract the value.

What you are doing is to look for (0) or (1) results.

(cnt >= 10 && cnt <= 20) returns either true or false.

--edit-- you can't use case with boolean (logic) experessions. The statement cnt >= 10 returns zero for false or one for true. Hence, it will we case(1) or case(0) which will never match to the length. --edit--

Since the other answers explained how to do it without actually explaining why it works:

When the switch executes, it finds the first matching case statement and then executes each line of code after the switch until it hits either a break statement or the end of the switch (or a return statement to leave the entire containing function). When you deliberately omit the break so that code under the next case gets executed too that's called a fall-through. So for the OP's requirement:

switch (pageid) {
   case "listing-page":
   case "home-page":
      alert("hello");
      break;

   case "details-page":
      alert("goodbye");
      break;
} 

Forgetting to include break statements is a fairly common coding mistake and is the first thing you should look for if your switch isn't working the way you expected. For that reason some people like to put a comment in to say "fall through" to make it clear when break statements have been omitted on purpose. I do that in the following example since it is a bit more complicated and shows how some cases can include code to execute before they fall-through:

switch (someVar) {
   case 1:
      someFunction();
      alert("It was 1");
      // fall through
   case 2:
      alert("The 2 case");
      // fall through
   case 3:
      // fall through
   case 4:
      // fall through
   case 5:
      alert("The 5 case");
      // fall through
   case 6:
      alert("The 6 case");
      break;

   case 7:
      alert("Something else");
      break;

   case 8:
      // fall through
   default:
      alert("The end");
      break;
}

You can also (optionally) include a default case, which will be executed if none of the other cases match - if you don't include a default and no cases match then nothing happens. You can (optionally) fall through to the default case.

So in my second example if someVar is 1 it would call someFunction() and then you would see four alerts as it falls through multiple cases some of which have alerts under them. Is someVar is 3, 4 or 5 you'd see two alerts. If someVar is 7 you'd see "Something else" and if it is 8 or any other value you'd see "The end".

Please try that:

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

    $(".addCF").click(function(){ $("#customFields").append(add); });

    $("#customFields").on('click','.remCF',function(){
        var inx = $('.remCF').index(this);
        $('tr').eq(inx+1).remove();
    });
});
</script>

Bugs caused by missing predefined folder for store compiled class file which is normally is /out folder by default. You can give a try to close Intellij > Import Project > From existing source. This will solve this problem.

if still item not removed use this magic method :)

private void deleteItem(int position) {
        mDataSet.remove(position);
        notifyItemRemoved(position);
        notifyItemRangeChanged(position, mDataSet.size());
        holder.itemView.setVisibility(View.GONE);
}

Kotlin version

private fun deleteItem(position: Int) {
    mDataSet.removeAt(position)
    notifyItemRemoved(position)
    notifyItemRangeChanged(position, mDataSet.size)
    holder.itemView.visibility = View.GONE
}

if you have only one xml in your table, you can convert it in 2 steps:

CREATE TABLE Batches( 
   BatchID int,
   RawXml xml 
)

declare @xml xml=(select top 1 RawXml from @Batches)

SELECT  --b.BatchID,
        x.XmlCol.value('(ReportHeader/OrganizationReportReferenceIdentifier)[1]','VARCHAR(100)') AS OrganizationReportReferenceIdentifier,
        x.XmlCol.value('(ReportHeader/OrganizationNumber)[1]','VARCHAR(100)') AS OrganizationNumber
FROM    @xml.nodes('/CasinoDisbursementReportXmlFile/CasinoDisbursementReport') x(XmlCol)

In case anyone else stumbles across this question, this is probably what you were looking for:

.grabbable {
    cursor: move; /* fallback if grab cursor is unsupported */
    cursor: grab;
    cursor: -moz-grab;
    cursor: -webkit-grab;
}

 /* (Optional) Apply a "closed-hand" cursor during drag operation. */
.grabbable:active {
    cursor: grabbing;
    cursor: -moz-grabbing;
    cursor: -webkit-grabbing;
}

Since awk and perl are closely related...

Perl equivalents of @Dennis's awk solutions:

To print the second line:
perl -ne 'print if $. == 2' file

To print the second field:
perl -lane 'print $F[1]' file

To print the third field of the fifth line:
perl -lane 'print $F[2] if $. == 5' file

Perl equivalent of @Glenn's solution:

Print the j'th field of the i'th line

perl -lanse 'print $F[$j-1] if $. == $i' -- -i=5 -j=3 file

Perl equivalents of @Hai's solutions:

if you are looking for second columns that contains abc:

perl -lane 'print if $F[1] =~ /abc/' foo

... and if you want to print only a particular column:

perl -lane 'print $F[2] if $F[1] =~ /abc/' foo

... and for a particular line number:

perl -lane 'print $F[2] if $F[1] =~ /abc/ && $. == 5' foo

-l removes newlines, and adds them back in when printing
-a autosplits the input line into array @F, using whitespace as the delimiter
-n loop over each line of the input file
-e execute the code within quotes
$F[1] is the second element of the array, since Perl starts at 0
$. is the line number

The difference

android:layout_gravity is the Outside gravity of the View. Specifies the direction in which the View should touch its parent's border.

android:gravity is the Inside gravity of that View. Specifies in which direction its contents should align.

HTML/CSS Equivalents

(if you are coming from a web development background)

Android                 | CSS
————————————————————————+————————————
android:layout_gravity  | float
android:gravity         | text-align

Easy trick to help you remember

Take layout-gravity as "Lay-outside-gravity".

You do not need to create sub directory. Just create blob container and use file name like the variable filename as below code:

string filename = "document/tech/user-guide.pdf";
CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(ConnectionString);
CloudBlockBlob blob = cloudBlobContainer.GetBlockBlobReference(filename);
blob.StreamWriteSizeInBytes = 20 * 1024;
blob.UploadFromStream(fileStream); // fileStream is System.IO.Stream

If you are looking for a custom configuration section like following

<CustomApplicationConfig>
        <Credentials Username="itsme" Password="mypassword"/>
        <PrimaryAgent Address="10.5.64.26" Port="3560"/>
        <SecondaryAgent Address="10.5.64.7" Port="3570"/>
        <Site Id="123" />
        <Lanes>
          <Lane Id="1" PointId="north" Direction="Entry"/>
          <Lane Id="2" PointId="south" Direction="Exit"/>
        </Lanes> 
</CustomApplicationConfig>

then you can use my implementation of configuration section so to get started add System.Configuration assembly reference to your project

Look at the each nested elements I used, First one is Credentials with two attributes so lets add it first

Credentials Element

public class CredentialsConfigElement : System.Configuration.ConfigurationElement
    {
        [ConfigurationProperty("Username")]
        public string Username
        {
            get 
            {
                return base["Username"] as string;
            }
        }

        [ConfigurationProperty("Password")]
        public string Password
        {
            get
            {
                return base["Password"] as string;
            }
        }
    }

PrimaryAgent and SecondaryAgent

Both has the same attributes and seem like a Address to a set of servers for a primary and a failover, so you just need to create one element class for both of those like following

public class ServerInfoConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Address")]
        public string Address
        {
            get
            {
                return base["Address"] as string;
            }
        }

        [ConfigurationProperty("Port")]
        public int? Port
        {
            get
            {
                return base["Port"] as int?;
            }
        }
    }

I'll explain how to use two different element with one class later in this post, let us skip the SiteId as there is no difference in it. You just have to create one class same as above with one property only. let us see how to implement Lanes collection

it is splitted in two parts first you have to create an element implementation class then you have to create collection element class

LaneConfigElement

public class LaneConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Id")]
        public string Id
        {
            get
            {
                return base["Id"] as string;
            }
        }

        [ConfigurationProperty("PointId")]
        public string PointId
        {
            get
            {
                return base["PointId"] as string;
            }
        }

        [ConfigurationProperty("Direction")]
        public Direction? Direction
        {
            get
            {
                return base["Direction"] as Direction?;
            }
        }
    }

    public enum Direction
    { 
        Entry,
        Exit
    }

you can notice that one attribute of LanElement is an Enumeration and if you try to use any other value in configuration which is not defined in Enumeration application will throw an System.Configuration.ConfigurationErrorsException on startup. Ok lets move on to Collection Definition

[ConfigurationCollection(typeof(LaneConfigElement), AddItemName = "Lane", CollectionType = ConfigurationElementCollectionType.BasicMap)]
    public class LaneConfigCollection : ConfigurationElementCollection
    {
        public LaneConfigElement this[int index]
        {
            get { return (LaneConfigElement)BaseGet(index); }
            set
            {
                if (BaseGet(index) != null)
                {
                    BaseRemoveAt(index);
                }
                BaseAdd(index, value);
            }
        }

        public void Add(LaneConfigElement serviceConfig)
        {
            BaseAdd(serviceConfig);
        }

        public void Clear()
        {
            BaseClear();
        }

        protected override ConfigurationElement CreateNewElement()
        {
            return new LaneConfigElement();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((LaneConfigElement)element).Id;
        }

        public void Remove(LaneConfigElement serviceConfig)
        {
            BaseRemove(serviceConfig.Id);
        }

        public void RemoveAt(int index)
        {
            BaseRemoveAt(index);
        }

        public void Remove(String name)
        {
            BaseRemove(name);
        }

    }

you can notice that I have set the AddItemName = "Lane" you can choose whatever you like for your collection entry item, i prefer to use "add" the default one but i changed it just for the sake of this post.

Now all of our nested Elements have been implemented now we should aggregate all of those in a class which has to implement System.Configuration.ConfigurationSection

CustomApplicationConfigSection

public class CustomApplicationConfigSection : System.Configuration.ConfigurationSection
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(CustomApplicationConfigSection));
        public const string SECTION_NAME = "CustomApplicationConfig";

        [ConfigurationProperty("Credentials")]
        public CredentialsConfigElement Credentials
        {
            get
            {
                return base["Credentials"] as CredentialsConfigElement;
            }
        }

        [ConfigurationProperty("PrimaryAgent")]
        public ServerInfoConfigElement PrimaryAgent
        {
            get
            {
                return base["PrimaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("SecondaryAgent")]
        public ServerInfoConfigElement SecondaryAgent
        {
            get
            {
                return base["SecondaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("Site")]
        public SiteConfigElement Site
        {
            get
            {
                return base["Site"] as SiteConfigElement;
            }
        }

        [ConfigurationProperty("Lanes")]
        public LaneConfigCollection Lanes
        {
            get { return base["Lanes"] as LaneConfigCollection; }
        }
    }

Now you can see that we have two properties with name PrimaryAgent and SecondaryAgent both have the same type now you can easily understand why we had only one implementation class against these two element.

Before you can use this newly invented configuration section in your app.config (or web.config) you just need to tell you application that you have invented your own configuration section and give it some respect, to do so you have to add following lines in app.config (may be right after start of root tag).

<configSections>
    <section name="CustomApplicationConfig" type="MyNameSpace.CustomApplicationConfigSection, MyAssemblyName" />
  </configSections>

NOTE: MyAssemblyName should be without .dll e.g. if you assembly file name is myDll.dll then use myDll instead of myDll.dll

to retrieve this configuration use following line of code any where in your application

CustomApplicationConfigSection config = System.Configuration.ConfigurationManager.GetSection(CustomApplicationConfigSection.SECTION_NAME) as CustomApplicationConfigSection;

I hope above post would help you to get started with a bit complicated kind of custom config sections.

Happy Coding :)

****Edit**** To Enable LINQ on LaneConfigCollection you have to implement IEnumerable<LaneConfigElement>

And Add following implementation of GetEnumerator

public new IEnumerator<LaneConfigElement> GetEnumerator()
        {
            int count = base.Count;
            for (int i = 0; i < count; i++)
            {
                yield return base.BaseGet(i) as LaneConfigElement;
            }
        }

for the people who are still confused about how yield really works read this nice article

Two key points taken from above article are

it doesn’t really end the method’s execution. yield return pauses the method execution and the next time you call it (for the next enumeration value), the method will continue to execute from the last yield return call. It sounds a bit confusing I think… (Shay Friedman)

Yield is not a feature of the .Net runtime. It is just a C# language feature which gets compiled into simple IL code by the C# compiler. (Lars Corneliussen)

a=[]
for j in range(3):
    a.append([int(i) for  i in input().split()])

In this above code the given input i.e Mike 18 Kevin 35 Angel 56, will be stored in an array 'a' and gives the output as [['Mike', '18'], ['Kevin', '35'], ['Angel', '56']].

With pure HTML you can't influence this - every modern browser (= the user) has complete control over this behavior because it has been misused a lot in the past...

HTML option

You can open a new window (HTML4) or a new browsing context (HTML5). Browsing context in modern browsers is mostly "new tab" instead of "new window". You have no influence on that, and you can't "force" modern browsers to open a new window.

In order to do this, use the anchor element's attribute target^[1]. The value you are looking for is _blank^[2].

<a href="www.example.com/example.html" target="_blank">link text</a>

JavaScript option

Forcing a new window is possible via javascript - see Ievgen's excellent answer below for a javascript solution.

(!) However, be aware, that opening windows via javascript (if not done in the onclick event from an anchor element) are subject to getting blocked by popup blockers!

_{[1] This attribute dates back to the times when browsers did not have tabs and using framesets was state of the art. In the meantime, the functionality of this attribute has slightly changed (see MDN Docu)}

_{[2] There are some other values which do not make much sense anymore (because they were designed with framesets in mind) like _parent, _self or _top.}

$ git push origin develop:master

or, more generally

$ git push <remote> <local branch name>:<remote branch to push into>

Try this code it's really working.

int number = 0;
try {
    number = Integer.parseInt(YourEditTextName.getText().toString());
} catch(NumberFormatException e) {
   System.out.println("parse value is not valid : " + e);
}

I got the same issue and found that it was due to wrong parameters. In views.py, I used:

return render(request, 'demo.html',{'items', items})    

But I found the issue: {'items', items}. Changing to {'items': items} resolved the issue.

I faced the error,
problem was FORM METHOD

{{ Form::open(array('url' => 'admin/doctor/edit/'.$doctor->doctor_id,'class'=>'form-horizontal form-bordered form-row-stripped','method' => 'PUT','files'=>true)) }}

It should be like this

{{ Form::open(array('url' => 'admin/doctor/edit/'.$doctor->doctor_id,'class'=>'form-horizontal form-bordered form-row-stripped','method' => 'POST','files'=>true)) }}

Forget it; this might work with Outlook or maybe even GMail but you won't be able to get this working properly supporting most other E-mail clients out there (and there's a shitton of 'em).

You're better of using a simple PHP script (check out PHPMailer) or use a hosted solution (Google "email form hosted", "free email form hosting" or something similar)

By the way, you are looking for the term "Percent-encoding" (also called url-encoding and Javascript uses encodeUri/encodeUriComponent (make sure you understand the differences!)). You will need to encode a whole lot more than just newlines.

Here is what I uses to search for multiple words in multiple columns - SQL server

Hope my answer help someone :) Thanks

declare @searchTrm varchar(MAX)='one two three ddd 20   30 comment'; 
--select value from STRING_SPLIT(@searchTrm, ' ') where trim(value)<>''
select * from Bols 
WHERE EXISTS (SELECT value  
    FROM STRING_SPLIT(@searchTrm, ' ')  
    WHERE 
        trim(value)<>''
        and(    
        BolNumber like '%'+ value+'%'
        or UserComment like '%'+ value+'%'
        or RequesterId like '%'+ value+'%' )
        )

Another recursive approach:

# change directory to target folder:
cd /Volumes/path/to/folder

# find all things of type "f" (file), 
# then pipe "|" each result as an argument (xargs -0) 
# to the "xattr -c" command:
find . -type f -print0 | xargs -0 xattr -c

# Sometimes you may have to use a star * instead of the dot.
# The dot just means "here" (whereever your cd'd to
find * -type f -print0 | xargs -0 xattr -c

I was trying to take the dump of the db which was running on the docker and came up with the below command to achieve the same:

docker exec <container_id/name> /usr/bin/mysqldump -u <db_username> --password=<db_password> db_name > .sql

Hope this helps!

You're looking for JSON.stringify().

There's no way this could influence anything in Java, since there's no (direct non-API) way to map some bytes directly into an int in Java.

Every API that does this or something similar defines the behaviour pretty precisely, so you should look up the documentation of that API.

I have used this with success in Chrome, Firefox, and Safari. Haven't been able to test it in IE yet.

if($(document).scrollTop() !=0){
    $('html, body').animate({ scrollTop: 0 }, 'fast');
}

The reason for the "if" statement is to check if the user is all ready at the top of the site. If so, don't do the animation. That way we don't have to worry so much about screen resolution.

The reason I use $(document).scrollTop instead of ie. $('html,body') is cause Chrome always return 0 for some reason.

I use File -> Switch Workspace -> Other... and type in my new workspace name.

(EDIT: Added the composite screen shot.)

Once in the new workspace, File -> Import... and under General choose "Existing Projects into Workspace. Press the Next button and then Browse for the old projects you would like to import. Check "Copy projects into workspace" to make a copy.

Personally I like to validate the form on submit and if there are errors, just return false.

$('form').submit(function() {

    var error;

   if ( !$('input').val() ) {
        error = true
    }

    if (error) {
         alert('there are errors')
         return false
    }

});

As I stated in comment i would use a box layout for this.

JPanel panel = new JPanel();
panel.setLayout(new BoxLayout());

JButton button = new JButton("Button1");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button2");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button3");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

add(panel);

Upload image with form data using NSURLConnection class in Swift 2.2:

    func uploadImage(){
        let imageData = UIImagePNGRepresentation(UIImage(named: "dexter.jpg")!)

        if imageData != nil{
            let str = "https://staging.mywebsite.com/V2.9/uploadfile"
            let request = NSMutableURLRequest(URL: NSURL(string:str)!)
            request.HTTPMethod = "POST"

            let boundary = NSString(format: "---------------------------14737809831466499882746641449")

            let contentType = NSString(format: "multipart/form-data; boundary=%@",boundary)
            request.addValue(contentType as String, forHTTPHeaderField: "Content-Type")

            let body = NSMutableData()

            // append image data to body
            body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(NSString(format:"Content-Disposition: form-data; name=\"file\"; filename=\"img.jpg\"\\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(NSString(format: "Content-Type: application/octet-stream\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(imageData!)
            body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)

            request.HTTPBody = body

            do {
                let returnData = try NSURLConnection.sendSynchronousRequest(request, returningResponse: nil)
                let returnString = NSString(data: returnData, encoding: NSUTF8StringEncoding)
                print("returnString = \(returnString!)")
            }
            catch let  error as NSError {
                print(error.description)
            }
        }
    }

Note: Always use sendAsynchronousRequest method instead of sendSynchronousRequest for uploading/downloading data to avoid blocking main thread. Here I used sendSynchronousRequest for testing purpose only.

I try my darned best to write exception-safe code, yes.

That means I take care to keep an eye on which lines can throw. Not everyone can, and it is critically important to keep that in mind. The key is really to think about, and design your code to satisfy, the exception guarantees defined in the standard.

Can this operation be written to provide the strong exception guarantee? Do I have to settle for the basic one? Which lines may throw exceptions, and how can I ensure that if they do, they don't corrupt the object?

If you were using Spring Boot (you mentioned that you're working with an old application, so you probably aren't but it might be of use to others), then you could use org.springframework.boot.test.rule.OutputCapture in the following manner:

@Rule
public OutputCapture outputCapture = new OutputCapture();

@Test
public void out() {
    System.out.print("hello");
    assertEquals(outputCapture.toString(), "hello");
}

It is in a folder with your application's name in Application Data folder in User's home folder (C:\documents and settings\user on xp and c:\users\user on Windows Vista).

There is some information here also.

PS:- try accessing it by %appdata% in run box!

This might be an edge case, but in my case the problem was not the client conf (I already had curl.cainfo configured in php.ini), but rather the remote server not being configured properly:

It did not send any intermediate certs in the chain. There was no error browsing the site using Chrome, but with PHP I got following error.

cURL error 60

After including the Intermediate Certs in the remote webserver configuration it worked.

You can use this site to check the SSL configuration of your server:

You could use following code:

<style>
    .svgwrapper {
        position: relative;
    }
    .svgwrapper {
        position: absolute;
        z-index: -1;
    }
</style>

<div class="svgwrapper" onClick="function();">
    <object src="blah" />
</div>

b3ng0 wrote similar code but it does not work. z-index of parent must be auto.

@gimel's answer is correct if you can guarantee the package hierarchy he mentions. If you can't -- if your real need is as you expressed it, exclusively tied to directories and without any necessary relationship to packaging -- then you need to work on __file__ to find out the parent directory (a couple of os.path.dirname calls will do;-), then (if that directory is not already on sys.path) prepend temporarily insert said dir at the very start of sys.path, __import__, remove said dir again -- messy work indeed, but, "when you must, you must" (and Pyhon strives to never stop the programmer from doing what must be done -- just like the ISO C standard says in the "Spirit of C" section in its preface!-).

Here is an example that may work for you:

import sys
import os.path
sys.path.append(
    os.path.abspath(os.path.join(os.path.dirname(__file__), os.path.pardir)))

import module_in_parent_dir

A procedure can't return a table as such. However you can select from a table in a procedure and direct it into a table (or table variable) like this:

create procedure p_x
as
begin
declare @t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert @t values('a', 1,1,1)
insert @t values('b', 2,2,2)

select * from @t
end
go

declare @t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert @t
exec p_x

select * from @t

You can replace it with its clone like so

var clone = $('#control').clone();

$('#control').replacewith(clone);

But this clones with its value too so you had better like so

var emtyValue = $('#control').val('');
var clone = emptyValue.clone();

$('#control').replacewith(clone);

Simplified:

• Static linking: one large executable
• Dynamic linking: a small executable plus one or more library files (.dll files on Windows, .so on Linux, or .dylib on macOS)

the solution to your problem looks like this:

public class Category {
  public long CategoryId { get; set; }
  public string CategoryName { get; set; }
} 

...

public class CategoryEqualityComparer : IEqualityComparer<Category>
{
   public bool Equals(Category x, Category y)
     => x.CategoryId.Equals(y.CategoryId)
          && x.CategoryName .Equals(y.CategoryName, 
 StringComparison.OrdinalIgnoreCase);

   public int GetHashCode(Mapping obj)
     => obj == null 
         ? 0
         : obj.CategoryId.GetHashCode()
           ^ obj.CategoryName.GetHashCode();
}

...

 var distinctCategories = product
     .Select(_ => 
        new Category {
           CategoryId = _.CategoryId, 
           CategoryName = _.CategoryName
        })
     .Distinct(new CategoryEqualityComparer())
     .ToList();

If there is no hard requirement on the length of the truncated string, one can use this to truncate and prevent cutting the last word as well:

$text = "Knowledge is a natural right of every human being of which no one
has the right to deprive him or her under any pretext, except in a case where a
person does something which deprives him or her of that right. It is mere
stupidity to leave its benefits to certain individuals and teams who monopolize
these while the masses provide the facilities and pay the expenses for the
establishment of public sports.";

// we don't want new lines in our preview
$text_only_spaces = preg_replace('/\s+/', ' ', $text);

// truncates the text
$text_truncated = mb_substr($text_only_spaces, 0, mb_strpos($text_only_spaces, " ", 50));

// prevents last word truncation
$preview = trim(mb_substr($text_truncated, 0, mb_strrpos($text_truncated, " ")));

In this case, $preview will be "Knowledge is a natural right of every human being".

For Mojave users, I found this page very useful, particularly this suggestion:

/usr/bin/wish $(which gitk)

...without that, the window did not display correctly!

Either override the OnFormClosing or register for the event FormClosing.

This is an example of overriding the OnFormClosing function in the derived form:

protected override void OnFormClosing(FormClosingEventArgs e)
{
   e.Cancel = true;
}

This is an example of the handler of the event to stop the form from closing which can be in any class:

private void FormClosing(object sender,FormClosingEventArgs e)
{  
   e.Cancel = true;
}

To get more advanced, check the CloseReason property on the FormClosingEventArgs to ensure the appropriate action is performed. You might want to only do the alternative action if the user tries to close the form.

Here's an explanation of the let keyword with some examples.

let works very much like var. The main difference is that the scope of a var variable is the entire enclosing function

This table on Wikipedia shows which browsers support Javascript 1.7.

Note that only Mozilla and Chrome browsers support it. IE, Safari, and potentially others don't.

head takes the first lines from a file, and the -n parameter can be used to specify how many lines should be extracted:

line=$(head -n 1 filename)

I'm currently writing an Objective-C++ framework called Objective-X, wich makes PURE C++ iPHONE PROGRAMMING possible. You can do like this:

#import "ObjectiveX.h"

void GUIApplicationMain() {    
    GUIAlert Alert;
    GUILabel Label;
    GUIScreen MainScreen;

    Alert.set_text(@"Just a lovely alert box!");
    Alert.set_title(@"Hello!");
    Alert.set_button(@"Okay");
    Alert.show();

    Label.set_text(@"Ciao!");
    Label.set_position(100, 200, 120, 40);

    MainScreen.init();
    MainScreen.addGUIControl(Label.init());    
}

and compile it using GCC's appropriate commandline options. I've already compiled this helloworld app&it w0rkX0rz like a charm. ;-) It'll available soon on GoogleCode. Search for Objective-X or visit http://infotronix.orgfree.com/objectivex approx. a week later!

This is an old post, but given the title of this question, the END option should be described in more detail. This can be used to stop ALL PROCEDURES (not just the subroutine running). It can also be used within a function to stop other Subroutines (which I find useful for some add-ins I work with).

As Microsoft states:

Terminates execution immediately. Never required by itself but may be placed anywhere in a procedure to end code execution, close files opened with the Open statement, and to clear variables*. I noticed that the END method is not described in much detail. This can be used to stop ALL PROCEDURES (not just the subroutine running).

Here is an illustrative example:

Sub RunSomeMacros()

    Call FirstPart
    Call SecondPart

    'the below code will not be executed if user clicks yes during SecondPart.
    Call ThirdPart
    MsgBox "All of the macros have been run."

End Sub

Private Sub FirstPart()
    MsgBox "This is the first macro"

End Sub

Private Sub SecondPart()
    Dim answer As Long
    answer = MsgBox("Do you want to stop the macros?", vbYesNo)

    If answer = vbYes Then
        'Stops All macros!
        End
    End If

    MsgBox "You clicked ""NO"" so the macros are still rolling..."
End Sub

Private Sub ThirdPart()
    MsgBox "Final Macro was run."
End Sub

You need a special type of function known as a table valued function. Below is a somewhat long-winded example that builds a date dimension for a data warehouse. Note the returns clause that defines a table structure. You can insert anything into the table variable (@DateHierarchy in this case) that you want, including building a temporary table and copying the contents into it.

if object_id ('ods.uf_DateHierarchy') is not null
    drop function ods.uf_DateHierarchy
go

create function ods.uf_DateHierarchy (

Using WIN + Q worked for me. Just q alone gave me "command not found" and eventually it jumped back into the git diff insanity.

Check existing row with Any.

    public static void insertOrUpdateCustomer(Customer customer)
    {
        using (var db = getDb())
        {

            db.Entry(customer).State = !db.Customer.Any(f => f.CustomerId == customer.CustomerId) ? EntityState.Added : EntityState.Modified;
            db.SaveChanges();

        }

    }

I suppose this is a cleaner approach. It works with inline height and width properties (I set random value in the fiddle to prove that) and with CSS max-width property.

HTML:

<div class="wrapper">
    <div class="h_iframe">
        <iframe height="2" width="2" src="http://www.youtube.com/embed/WsFWhL4Y84Y" frameborder="0" allowfullscreen></iframe>
    </div>
    <p>Please scale the "result" window to notice the effect.</p>
</div>

CSS:

html,body        {height: 100%;}
.wrapper         {width: 80%; max-width: 600px; height: 100%; margin: 0 auto; background: #CCC}
.h_iframe        {position: relative; padding-top: 56%;}
.h_iframe iframe {position: absolute; top: 0; left: 0; width: 100%; height: 100%;}

This is how i registered my domain:

sudo letsencrypt --apache -d mydomain.com

Then it was possible to use the same command with additional domains and follow the instructions:

sudo letsencrypt --apache -d mydomain.com,x.mydomain.com,y.mydomain.com

You can set the height and width of your divs with css.

<style type="text/css">
.box {
     height: 150px;
     width: 150px;
}
</style> 

Is this what you're looking for?

With WinForms you can use the ErrorProvider in conjunction with the Validating event to handle the validation of user input. The Validating event provides the hook to perform the validation and ErrorProvider gives a nice consistent approach to providing the user with feedback on any error conditions.

Command CHCP shows the current codepage. It has three digits: 8xx and is different from Windows 12xx. So typing a English-only text you wouldn't see any difference, but an extended codepage (like Cyrillic) will be printed wrongly.

Check out the image-map plugin on Github. It works both with vanilla JavaScript and as a jQuery plugin.

$('img[usemap]').imageMap();     // jQuery

ImageMap('img[usemap]')          // JavaScript

Check out the demo.

This is by design. You can cast null to any reference type. Otherwise you wouldn't be able to assign it to reference variables.

you can't get city location by ip. here you can get country with jquery:

$.get("http://ip-api.com/json", function(response) {
console.log(response.country);}, "jsonp");

Here is a simple way to define those constants, and I'm pretty sure it's portable:

const double inf = 1.0/0.0;
const double nan = 0.0/0.0;

When I run this code:

printf("inf  = %f\n", inf);
printf("-inf = %f\n", -inf);
printf("nan  = %f\n", nan);
printf("-nan = %f\n", -nan);

I get:

inf  = inf
-inf = -inf
nan  = -nan
-nan = nan

It all depends on how its going to be used. If you will want to switch back and forth between these two panels then use a CardLayout. If you are only switching from the first to the second once and (and not going back) then I would use telcontars suggestion and just replace it. Though if the JPanel isn't the only thing in your frame I would use remove(java.awt.Component) instead of removeAll.

If you are somewhere in between these two cases its basically a time-space tradeoff. The CardLayout will save you time but take up more memory by having to keep this whole other panel in memory at all times. But if you just replace the panel when needed and construct it on demand, you don't have to keep that meory around but it takes more time to switch.

Also you can try a JTabbedPane to use tabs instead (its even easier than CardLayout because it handles the showing/hiding automitically)

textView.textContainerInset = UIEdgeInsetsZero;
NSString *string = @"Some string";
NSDictionary *attributes = @{NSFontAttributeName:[UIFont systemFontOfSize:12.0f], NSForegroundColorAttributeName:[UIColor blackColor]};
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:string attributes:attributes];
[textView setAttributedText:attributedString];
CGRect textViewFrame = [textView.attributedText boundingRectWithSize:CGSizeMake(CGRectGetWidth(self.view.frame)-8.0f, 9999.0f) options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading) context:nil];
NSLog(@"%f", ceilf(textViewFrame.size.height));

Works on all fonts perfectly!

It looks like you want the indices of the duplicates. Here is some short code that will find those in O(n) time, without using any packages:

dups = {}
[dups.setdefault(v, []).append(i) for i, v in enumerate(mylist)]
dups = {k: v for k, v in dups.items() if len(v) > 1}
# dups now has keys for all the duplicate values
# and a list of matching indices for each

# The second line produces an unused list. 
# It could be replaced with this:
for i, v in enumerate(mylist):
    dups.setdefault(v, []).append(i)

PATH: Answered long ago, however, it maybe more helpful to think of -p as "Path" (easier to remember), as in this causes mkdir to create every part of the path that isn't already there.

mkdir -p /usr/bin/comm/diff/er/fence

if /usr/bin/comm already exists, it acts like: mkdir /usr/bin/comm/diff mkdir /usr/bin/comm/diff/er mkdir /usr/bin/comm/diff/er/fence

As you can see, it saves you a bit of typing, and thinking, since you don't have to figure out what's already there and what isn't.

Currently there is a far simpler solution than the ones already provided. When running your application you just have to pass along the threaded=True parameter to the app.run() call, like:

app.run(host="your.host", port=4321, threaded=True)

Another option as per what we can see in the werkzeug docs, is to use the processes parameter, which receives a number > 1 indicating the maximum number of concurrent processes to handle:

• threaded – should the process handle each request in a separate thread?
• processes – if greater than 1 then handle each request in a new process up to this maximum number of concurrent processes.

Something like:

app.run(host="your.host", port=4321, processes=3) #up to 3 processes

More info on the run() method here, and the blog post that led me to find the solution and api references.

Note: on the Flask docs on the run() methods it's indicated that using it in a Production Environment is discouraged because (quote): "While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well."

However, they do point to their Deployment Options page for the recommended ways to do this when going for production.

I'd say

chunks = [data[x:x+100] for x in range(0, len(data), 100)]

If you are using python 2.x instead of 3.x, you can be more memory-efficient by using xrange(), changing the above code to:

chunks = [data[x:x+100] for x in xrange(0, len(data), 100)]

Solved in my case, i look at

sudo tail -f /var/log/nginx/error.log

and error is php5-fpm.sock not found

I look at sudo ls -lah /var/run/

there was no php5-fpm.sock

I edit the www.conf  

sudo vim /etc/php5/fpm/pool.d/www.conf

change

listen = 127.0.0.1:9000

for

listen = /var/run/php5-fpm.sock

and reboot

Or if it's from a database context you can use

@Html.DropDownListFor(model => model.MyOption, db.MyOptions.Select(x => new SelectListItem { Text = x.Name, Value = x.Id.ToString() }))

Assuming that the mouse cursor should return to the document after window resize, we can create a callback-like behavior with onmouseover event. Don't forget that this solution may not work for touch-enabled screens as expected.

var resizeTimer;
var resized = false;
$(window).resize(function() {
   clearTimeout(resizeTimer);
   resizeTimer = setTimeout(function() {
       if(!resized) {
           resized = true;
           $(document).mouseover(function() {
               resized = false;
               // do something here
               $(this).unbind("mouseover");
           })
       }
    }, 500);
});

Similarly:

"".contains("");     // Returns true.

Therefore, it appears that an empty string is contained in any String.

>>> [el[0] if i < len(mylist) else el[1] for i,el in enumerate(mylist + mylist)]
['0,0', '1,0', '2,0', '0,1', '1,1', '2,1']

You can get Visual C++ Express Edition straight from Microsoft, if you want something targeting Win32. Otherwise MinGW or lcc, as suggested elsewhere.

In your particular case: if ($var).

You need to use isset if you don't know whether the variable exists or not. Since you declared it on the very first line though, you know it exists, hence you don't need to, nay, should not use isset.

The same goes for empty, only that empty also combines a check for the truthiness of the value. empty is equivalent to !isset($var) || !$var and !empty is equivalent to isset($var) && $var, or isset($var) && $var == true.

If you only want to test a variable that should exist for truthiness, if ($var) is perfectly adequate and to the point.

In kotlin you can do:

// instantiate the new fragment
val fragment: Fragment = ExampleFragment()

val transaction = supportFragmentManager.beginTransaction()
transaction.replace(R.id.book_description_fragment, fragment)
transaction.addToBackStack("transaction_name")
// Commit the transaction
transaction.commit()

the correct syntax is -

with t1
as
(select * from tab1
where conditions...
),
t2
as
(select * from tab2
where conditions...
(you can access columns of t1 here as well)
)
select * from t1, t2
where t1.col1=t2.col2;

For those using the latest distribution on windows, the following should be enough:

1. Download the command line tools from here
2. Extract it somewhere (e.g. C:\androidsdk)
3. Add ANDROID_SDK_TOOLS as environment variable pointing to where you extracted it (C:\androidsdk)
4. Create a folder named latest inside the cmdlime-tools you extracted. And move what's inside(bin,lib...) to the folder latest.
5. cd cmdline-tools/latest/bin and execute the following:

sdkmanager.bat system-images;android-29;default;x86_64 platforms;android-29 build-tools;29.0.3 extras;google;m2repository extras;android;m2repository

6. Agree to the terms and conditions and continue. voilà

The syntax of the query is as follows:

Alter table <table name> rename column <column name> to <new column name>;

Example:

Alter table employee rename column eName to empName;

To rename a column name without space to a column name with space:

Alter table employee rename column empName to "Emp Name";

To rename a column with space to a column name without space:

Alter table employee rename column "emp name" to empName;

If you do not want to install Xcode and/or MacPorts/Fink/Homebrew, you could always use the standalone installer: https://sourceforge.net/projects/git-osx-installer/

For Angular 2.0.0-rc.0 adding node_modules/angular2/typings/browser.d.ts won't work. First add typings.json file to your solution, with this content:

{
    "ambientDependencies": {
        "es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
    }
}

And then update the package.json file to include this postinstall:

"scripts": {
    "postinstall": "typings install"
},

Now run npm install

Also now you should ignore typings folder in your tsconfig.json file as well:

 "exclude": [
        "node_modules",
        "typings/main",
        "typings/main.d.ts"
    ]

Update

Now AngularJS 2.0 is using core-js instead of es6-shim. Follow its quick start typings.json file for more info.

Your example code is wrong. This works:

import datetime

datetime.datetime.strptime("21/12/2008", "%d/%m/%Y").strftime("%Y-%m-%d")

The call to strptime() parses the first argument according to the format specified in the second, so those two need to match. Then you can call strftime() to format the result into the desired final format.

Apache Commons Lang has

T[] t = ArrayUtils.add( initialArray, newitem );

it returns a new array, but if you're really working with arrays for some reason, this may be the ideal way to do this.

To expand on Jonathon Faust's and McDowell's answers: If you're on a *nix based system, you can use od (one of the earliest Unix programs¹ which should be available practically everywhere) to query the .class file on a binary level:

od -An -j7 -N1 -t dC SomeClassFile.class

This will output the familiar integer values, e.g. 50 for Java 5, 51 for Java 6 and so on.

¹ Quote from https://en.wikipedia.org/wiki/Od_(Unix)

If what you want can't be achieved satisfactorily without having the initialization in its own method (e.g. because you want to do too much before the initialization code, or wrap it in a try-finally, or whatever) you can have any or all constructors pass the readonly variables by reference to an initialization routine, which will then be able to manipulate them at will.

public class Sample
{
    private readonly int _intField;
    public int IntProperty => _intField; 

    private void setupStuff(ref int intField, int newValue) => intField = newValue;

    public Sample(string theIntAsString)
    {
        int i = int.Parse(theIntAsString);
        setupStuff(ref _intField,i);
    }

    public Sample(int theInt) => setupStuff(ref _intField, theInt);
}

If you have cloned your project from git or somewhere then first, you should type npm install.

You can also use conditional (ternary) operator inside conditional operator in case you have 2 different dependencies.

I recently encountered this error when I refereneced a project that was initiliazed via a git submodule.

I ended up finding out that the root build.gradle file of the submodule (a java project) did not have the java plugin applied at the root level.

It only had

apply plugin: 'idea'

I added the java plugin:

apply plugin: 'idea'
apply plugin: 'java'

Once I applied the java plugin the 'default not found' message disappeared and the build succeeded.

In my case, this error was caused by improper use of "fixture.detectChanges()" It seems this method is an event listener (async) which will only respond a callback when changes are detected. If no changes are detected it will not invoke the callback, resulting in a timeout error. Hope this helps :)
