In my case, I had multiple spaces(fields were separated by one or more space) that I wanted to replace with a tab. The following did it:

You need to use list-style-type: to change bullet type/style and the above link has all of the options listed. As others have stated the color is changed using the color property on the ul itself

To create 'black filled' bullets, use 'disc' instead of 'circle',i.e.:

list-style-type:disc

I spent a lot of time looking for a solution to this problem too. Here's what i've found thus far:

If you want your users to be able to click on a button and copy some text, you may have to use Flash.

If you want your users to press Ctrl+C anywhere on the page, but always copy xyz to the clipboard, I wrote an all-JS solution in YUI3 (although it could easily be ported to other frameworks, or raw JS if you're feeling particularly self-loathing).

It involves creating a textbox off the screen which gets highlighted as soon as the user hits Ctrl/CMD. When they hit 'C' shortly after, they copy the hidden text. If they hit 'V', they get redirected to a container (of your choice) before the paste event fires.

This method can work well, because while you listen for the Ctrl/CMD keydown anywhere in the body, the 'A', 'C' or 'V' keydown listeners only attach to the hidden text box (and not the whole body). It also doesn't have to break the users expectations - you only get redirected to the hidden box if you had nothing selected to copy anyway!

Here's what i've got working on my site, but check http://at.cg/js/clipboard.js for updates if there are any:

YUI.add('clipboard', function(Y) {


// Change this to the id of the text area you would like to always paste in to:

pasteBox = Y.one('#pasteDIV');


// Make a hidden textbox somewhere off the page.

Y.one('body').append('<input id="copyBox" type="text" name="result" style="position:fixed; top:-20%;" onkeyup="pasteBox.focus()">');
copyBox = Y.one('#copyBox');


// Key bindings for Ctrl+A, Ctrl+C, Ctrl+V, etc:

// Catch Ctrl/Window/Apple keydown anywhere on the page.
Y.on('key', function(e) {
    copyData();
        //  Uncomment below alert and remove keyCodes after 'down:' to figure out keyCodes for other buttons.
        //  alert(e.keyCode);
        //  }, 'body',  'down:', Y);
}, 'body',  'down:91,224,17', Y);

// Catch V - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // Oh no! The user wants to paste, but their about to paste into the hidden #copyBox!!
    // Luckily, pastes happen on keyPress (which is why if you hold down the V you get lots of pastes), and we caught the V on keyDown (before keyPress).
    // Thus, if we're quick, we can redirect the user to the right box and they can unload their paste into the appropriate container. phew.
    pasteBox.select();
}, '#copyBox',  'down:86', Y);

// Catch A - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // User wants to select all - but he/she is in the hidden #copyBox! That wont do.. select the pasteBox instead (which is probably where they wanted to be).
    pasteBox.select();
}, '#copyBox',  'down:65', Y);



// What to do when keybindings are fired:

// User has pressed Ctrl/Meta, and is probably about to press A,C or V. If they've got nothing selected, or have selected what you want them to copy, redirect to the hidden copyBox!
function copyData() {
    var txt = '';
    // props to Sabarinathan Arthanari for sharing with the world how to get the selected text on a page, cheers mate!
        if (window.getSelection) { txt = window.getSelection(); }
        else if (document.getSelection) { txt = document.getSelection(); }
        else if (document.selection) { txt = document.selection.createRange().text; }
        else alert('Something went wrong and I have no idea why - please contact me with your browser type (Firefox, Safari, etc) and what you tried to copy and I will fix this immediately!');

    // If the user has nothing selected after pressing Ctrl/Meta, they might want to copy what you want them to copy. 
        if(txt=='') {
                copyBox.select();
        }
    // They also might have manually selected what you wanted them to copy! How unnecessary! Maybe now is the time to tell them how silly they are..?!
        else if (txt == copyBox.get('value')) {
        alert('This site uses advanced copy/paste technology, possibly from the future.\n \nYou do not need to select things manually - just press Ctrl+C! \n \n(Ctrl+V will always paste to the main box too.)');
                copyBox.select();
        } else {
                // They also might have selected something completely different! If so, let them. It's only fair.
        }
}
});

Hope someone else finds this useful :]

sys.argv is the list of arguments passed to the Python program. The first argument, sys.argv[0], is actually the name of the program as it was invoked. That's not a Python thing, but how most operating systems work. The reason sys.argv[0] exists is so you can change your program's behaviour depending on how it was invoked. sys.argv[1] is thus the first argument you actually pass to the program.

Because lists (like most sequences) in Python start indexing at 0, and because indexing past the end of the list is an error, you need to check if the list has length 2 or longer before you can access sys.argv[1].

Since newcol is the ID of the radio button, You can simply use it as below.

$("#"+newcol).attr('checked',true);

I eventually figured out an easy way to do it:

1. On your Twitter feed, click the date/time of the tweet containing the video. That will open the single tweet view
2. Look for the down-pointing arrow at the top-right corner of the tweet, click it to open drop-down menue
3. Select the "Embed Video" option and copy the HTML embed code and Paste it to Notepad
4. Find the last "t.co" shortened URL inside the HTML code (should be something like this: https://``t.co/tQM43ftXyM). Copy this URL and paste it in a new browser tab.
5. The browser will expand the shortened URL to something which looks like this: https://twitter.com/UserName/status/828267001496784896/video/1

This is the link to the Twitter Card containing the native video. Pasting this link in a new tweet or DM will include the native video in it!

• Changing Values:
  • array_map cannot change the values inside input array(s) while array_walk can; in particular, array_map never changes its arguments.
• Array Keys Access:
  • array_map cannot operate with the array keys, array_walk can.
• Return Value:
  • array_map returns a new array, array_walk only returns true. Hence, if you don't want to create an array as a result of traversing one array, you should use array_walk.
• Iterating Multiple Arrays:
  • array_map also can receive an arbitrary number of arrays and it can iterate over them in parallel, while array_walk operates only on one.
• Passing Arbitrary Data to Callback:
  • array_walk can receive an extra arbitrary parameter to pass to the callback. This mostly irrelevant since PHP 5.3 (when anonymous functions were introduced).
• Length of Returned Array:
  • The resulting array of array_map has the same length as that of the largest input array; array_walk does not return an array but at the same time it cannot alter the number of elements of original array; array_filter picks only a subset of the elements of the array according to a filtering function. It does preserve the keys.

Example:

<pre>
<?php

$origarray1 = array(2.4, 2.6, 3.5);
$origarray2 = array(2.4, 2.6, 3.5);

print_r(array_map('floor', $origarray1)); // $origarray1 stays the same

// changes $origarray2
array_walk($origarray2, function (&$v, $k) { $v = floor($v); }); 
print_r($origarray2);

// this is a more proper use of array_walk
array_walk($origarray1, function ($v, $k) { echo "$k => $v", "\n"; });

// array_map accepts several arrays
print_r(
    array_map(function ($a, $b) { return $a * $b; }, $origarray1, $origarray2)
);

// select only elements that are > 2.5
print_r(
    array_filter($origarray1, function ($a) { return $a > 2.5; })
);

?>
</pre>

Result:

Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
0 => 2.4
1 => 2.6
2 => 3.5
Array
(
    [0] => 4.8
    [1] => 5.2
    [2] => 10.5
)
Array
(
    [1] => 2.6
    [2] => 3.5
)

You can try using open-cv to save the file since it helps with image type conversions internally. The sample code:

import cv2
import numpy as np

def save(encoded_data, filename):
    nparr = np.fromstring(encoded_data.decode('base64'), np.uint8)
    img = cv2.imdecode(nparr, cv2.IMREAD_ANYCOLOR)
    return cv2.imwrite(filename, img)

Then somewhere in your code you can use it like this:

save(base_64_string, 'testfile.png');
save(base_64_string, 'testfile.jpg');
save(base_64_string, 'testfile.bmp');

UPDATE 2020

With the new (yet in Editor's draft) CSS 4 properties you can achieve this by using min() and max() (also you can use clamp() as a - kind of - shorthand for both min() and max()

clamp(MIN, VAL, MAX) is resolved as max(MIN, min(VAL, MAX))

min() syntax:

min( <calc-sum># )

where 
<calc-sum> = <calc-product> [ [ '+' | '-' ] <calc-product> ]*

where 
<calc-product> = <calc-value> [ '*' <calc-value> | '/' <number> ]*

where 
<calc-value> = <number> | <dimension> | <percentage> | ( <calc-sum> )

max() syntax:

max( <calc-sum># )
    
where
<calc-sum> = <calc-product> [ [ '+' | '-' ] <calc-product> ]*
    
where  
<calc-product> = <calc-value> [ '*' <calc-value> | '/' <number> ]*

where 
<calc-value> = <number> | <dimension> | <percentage> | ( <calc-sum> )

clamp() syntax:

clamp( <calc-sum>#{3} )

where 
<calc-sum> = <calc-product> [ [ '+' | '-' ] <calc-product> ]*

where 
<calc-product> = <calc-value> [ '*' <calc-value> | '/' <number> ]*

where 
<calc-value> = <number> | <dimension> | <percentage> | ( <calc-sum> )

Old Answer

No you can't.

margin and padding properties don't have the min/max prefixes

An approximately way would be using relative units (vh/vw), but still not min/max

And as @vigilante_stark pointed out in the answer, the CSS calc() function could be another workaround, something like these:

/* demo */

* {
  box-sizing: border-box
}

section {
  background-color: red;
  width: 50vw;
  height: 50px;
  position: relative;
}

div {
  width: inherit;
  height: inherit;
  position: absolute;
  top: 0;
  left: 0
}


/* end of demo */

.min {
  /* demo */
  border: green dashed 4px;
  /*this your min padding-left*/
  padding-left: calc(50vw + 50px);
}

.max {
  /* demo */
  border: blue solid 3px;
  /*this your max padding-left*/
  padding-left: calc(50vw + 200px);
}

<section>
  <div class="min"></div>
  <div class="max"></div>

Hello Thanks for the question; To resolve: "Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'"

You need to tell the run to wait until the process is finished. Something like:

const DontWaitUntilFinished = false, ShowWindow = 1, DontShowWindow = 0, WaitUntilFinished = true
set oShell = WScript.CreateObject("WScript.Shell")
command = "cmd /c C:\windows\system32\wscript.exe <path>\myScript.vbs " & args
oShell.Run command, DontShowWindow, WaitUntilFinished

In the script itself, start Excel like so. While debugging start visible:

File = "c:\test\myfile.xls"
oShell.run """C:\Program Files\Microsoft Office\Office14\EXCEL.EXE"" " & File, 1, true

First you need to define the List as :

List<Map<String, ArrayList<String>>> list = new ArrayList<>();

To add the Map to the List , use add(E e) method :

list.add(map);

for Specific table you cannot use $this->db->insert_id() . even the last insert happened long ago it can be fetched like this. may be wrong. but working well for me

     $this->db->select_max('{primary key}');
     $result= $this->db->get('{table}')->row_array();
     echo $result['{primary key}'];

You can do what Hudson (continuous integration project) does. you download a war which can be deployed in tomcat or to execute using

java -jar hudson.war

(Because it has an embedded Jetty engine, running it from command line cause a server to be launched.) Anyway by looking at hudson's manifest I understand that they put a Main class in the root for the archive. In your case your war layout should be look like:

under root:

• mypackage/MyEntryPointClass.class
• WEB-INF/lib
• WEB-INF/classes
• META-INF/MANIFEST.MF

while the manifest should include the following line:

Main-Class: mypackage.MyEntryPointClass

please notice that the mypackage/MyEntryPointClass.class is accessable from the command line only, and the classes under WEB-INF/classes are accessable from the application server only.

    pgrep -f process_name > any_file_name
    sed -i 's/^/kill /' any_file_name
    chmod 777 any_file_name
    ./any_file_name

for example 'pgrep -f firefox' will grep the PID of running 'firefox' and will save this PID to a file called 'any_file_name'. 'sed' command will add the 'kill' in the beginning of the PID number in 'any_file_name' file. Third line will make 'any_file_name' file executable. Now forth line will kill the PID available in the file 'any_file_name'. Writing the above four lines in a file and executing that file can do the control-C. Working absolutely fine for me.

The reason is because you are using the transform property twice. Due to CSS rules with the cascade, the last declaration wins if they have the same specificity. As both transform declarations are in the same rule set, this is the case.

What it is doing is this:

1. rotate the text 90 degrees. Ok.
2. translate 50% by 50%. Ok, this is same property as step one, so do this step and ignore step 1.

See http://jsfiddle.net/Lx76Y/ and open it in the debugger to see the first declaration overwritten

As the translate is overwriting the rotate, you have to combine them in the same declaration instead: http://jsfiddle.net/Lx76Y/1/

To do this you use a space separated list of transforms:

#rotatedtext {
    transform-origin: left;
    transform: translate(50%, 50%) rotate(90deg) ;
}

Remember that they are specified in a chain, so the translate is applied first, then the rotate after that.

Set force Portrait or Landscape mode, Add lines respectively.

Import below line:

import android.content.pm.ActivityInfo;

Add Below line just above setContentView(R.layout.activity_main);

For Portrait:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//Set Portrait

For Landscap:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//Set Landscape

This will definitely work.

serialize() and unserialize() convert between php objects and a string representation.

$(function () {
    $( ".droppable-area" ).sortable({
                connectWith: ".connected-sortable",
                containment: ".droppable-area", //(parent div)
                stack: '.connected-sortable div'
            }).disableSelection();
});

Edit: thought of something else.

You say you're creating a form dynamically - do you really mean a <form> and its contents 'cause asp.net takes issue with multiple forms on a page and it's already creating one uberform for you.

This is and old question, but now on PHP 7.1 you can define constant visibility.

EXAMPLE

<?php
class Foo {
    // As of PHP 7.1.0
    public const BAR = 'bar';
    private const BAZ = 'baz';
}
echo Foo::BAR . PHP_EOL;
echo Foo::BAZ . PHP_EOL;
?>

Output of the above example in PHP 7.1:

bar

Fatal error: Uncaught Error: Cannot access private const Foo::BAZ in …

Note: As of PHP 7.1.0 visibility modifiers are allowed for class constants.

There is an app in google play known as MyAppSharer. Open the app, search for the app that you have installed, check apk and select share. The app would take some time and build the apk. You can then close the app. The apk of the file is located in /sdcard/MyAppSharer

This does not require rooting your phone and works only for apps that are currently installed on your phone

This is the best solution I have found for the error 404 on IIS 7.5 and .NET Framework 4.5 environment, and without using: runAllManagedModulesForAllRequests="true".

I followed this thread: https://forums.asp.net/t/2070064.aspx?Web+API+2+URL+routing+404+error+on+IIS+7+5+IIS+Express+works+fine and I have modified my web.config accordingly, and now the MVC web app works well on IIS 7.5 and .NET Framework 4.5 environment.

Sometimes it's better to use neither. For example, in a "dispatch" situation, Javascript lets you do things in a completely different way:

function dispatch(funCode) {
  var map = {
    'explode': function() {
      prepExplosive();
      if (flammable()) issueWarning();
      doExplode();
    },

    'hibernate': function() {
      if (status() == 'sleeping') return;
      // ... I can't keep making this stuff up
    },
    // ...
  };

  var thisFun = map[funCode];
  if (thisFun) thisFun();
}

Setting up multi-way branching by creating an object has a lot of advantages. You can add and remove functionality dynamically. You can create the dispatch table from data. You can examine it programmatically. You can build the handlers with other functions.

There's the added overhead of a function call to get to the equivalent of a "case", but the advantage (when there are lots of cases) of a hash lookup to find the function for a particular key.

Here's an approach on how you might implement a _class method that works as self.class for this situation. Note: Do not use this in production code, this is for interest-sake :)

i think the question is how to call the javascript function on pageload

Well, in obvious cases like that, you can always tell PHP to suppress messages by using "@" in front of the function.

$monthly_index = @array_shift(unpack('H*', date('m/Y')));

It may not be one of the best programming practices to suppress all errors this way, but in certain cases (like this one) it comes handy and is acceptable.

As result, I am sure your friend 'system administrator' will be pleased with a less polluted error.log.

There's an entire book on this topic, which is titled Large-Scale C++ Software Design (written by John Lakos).

The book pre-dates templates, so to the contents of that book add "using templates, too, can make the compiler slower".

I would use the "count" for having always an integer as a result

SqlCommand check_User_Name = new SqlCommand("SELECT count([user]) FROM Table WHERE ([user] = '" + txtBox_UserName.Text + "') " , conn);

int UserExist = (int)check_User_Name.ExecuteScalar();

if (UserExist == 1) //anything different from 1 should be wrong
{
  //Username Exist
}

You have to edit the eclipse.ini file to have an entry similar to this:

C:\Java\JDK\1.5\bin\javaw.exe (your location of java executable)
-vmargs
-Xms64m   (based on you memory requirements)
-Xmx1028m

Also remember that in eclipse.ini, anything meant for Eclipse should be before the -vmargs line and anything for JVM should be after the -vmargs line.

Use dropna:

dat.dropna()

You can pass param how to drop if all labels are nan or any of the labels are nan

dat.dropna(how='any')    #to drop if any value in the row has a nan
dat.dropna(how='all')    #to drop if all values in the row are nan

Hope that answers your question!

Edit 1: In case you want to drop rows containing nan values only from particular column(s), as suggested by J. Doe in his answer below, you can use the following:

dat.dropna(subset=[col_list])  # col_list is a list of column names to consider for nan values.

You can apply css like this:

div {
   word-wrap: break-word;
   width: 100px;
}

Usually browser does not break words, but word-wrap: break-word; will force it to break words too.

Demo: http://jsfiddle.net/Mp7tc/

I suspect that the problem lies in the fact that you are calling your state setter immediately inside the function component body, which forces React to re-invoke your function again, with the same props, which ends up calling the state setter again, which triggers React to call your function again.... and so on.

const SingInContainer = ({ message, variant}) => {
    const [open, setSnackBarState] = useState(false);
    const handleClose = (reason) => {
        if (reason === 'clickaway') {
          return;
        }
        setSnackBarState(false)

      };

    if (variant) {
        setSnackBarState(true); // HERE BE DRAGONS
    }
    return (
        <div>
        <SnackBar
            open={open}
            handleClose={handleClose}
            variant={variant}
            message={message}
            />
        <SignInForm/>
        </div>
    )
}

Instead, I recommend you just conditionally set the default value for the state property using a ternary, so you end up with:

const SingInContainer = ({ message, variant}) => {
    const [open, setSnackBarState] = useState(variant ? true : false); 
                                  // or useState(!!variant); 
                                  // or useState(Boolean(variant));
    const handleClose = (reason) => {
        if (reason === 'clickaway') {
          return;
        }
        setSnackBarState(false)

      };

    return (
        <div>
        <SnackBar
            open={open}
            handleClose={handleClose}
            variant={variant}
            message={message}
            />
        <SignInForm/>
        </div>
    )
}

Slack has a cool way of making tabs small viewport friendly on some of their admin pages. I made something similar using bootstrap. It's kind of a tabs ? dropdown.

Demo: http://jsbin.com/nowuyi/1

Here's what it looks like on a big viewport:

Here's how it looks collapsed on a small viewport:

Here's how it looks expanded on a small viewport:

the HTML is exactly the same as default bootstrap tabs.

There is a small JS snippet, which requires jquery (and inserts two span elements into the DOM):

$.fn.responsiveTabs = function() {
  this.addClass('responsive-tabs');
  this.append($('<span class="glyphicon glyphicon-triangle-bottom"></span>'));
  this.append($('<span class="glyphicon glyphicon-triangle-top"></span>'));

  this.on('click', 'li.active > a, span.glyphicon', function() {
    this.toggleClass('open');
  }.bind(this));

  this.on('click', 'li:not(.active) > a', function() {
    this.removeClass('open');

And then there is a lot of css (less):

@xs: 768px;


.responsive-tabs.nav-tabs {

  overflow: visible;

    &.glyphicon-triangle-top {
      display: none;
    }
    @media(min-width: @xs) {
      display: none;

      @media(min-width: @xs) {

      }
    }

    &.active {
      display: block;
      a {
        @media(min-width: @xs) {
          border-bottom-color: transparent; 
        }
        border: 1px solid #DDDDDD;
        border-radius: 2px;
      }
    }

    @media(min-width: @xs) {
      display: block;
      float: left;
    }

  }

  }
}

Depending on how it's being used, it might be necessary and even handy. http://php.net/manual/en/language.operators.logical.php

// "||" has a greater precedence than "or"

// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;

// The constant false is assigned to $f and then true is ignored
// Acts like: (($f = false) or true)
$f = false or true;

But in most cases it seems like more of a developer taste thing, like every occurrence of this that I've seen in CodeIgniter framework like @Sarfraz has mentioned.

For me this is what I use if adding \n is not a problem.

fmt.Sprintf("Hello World\nHow are you doing today\nHope all is well with your go\nAnd code")

Else you can use the raw string

multiline := `Hello Brothers and sisters of the Code
              The grail needs us.
             `

Simply put, you need to rewrite all of your database connections and queries.

You are using mysql_* functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.

A basic example of using PDO (without error handling):

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>

A basic example of using MySQLi (without error handling):

$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");

Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.

This is an excellent question and I run in to this a lot at work actually. There are a lot of "technically correct" answers such as 65k and 1500. I've done a lot of work writing network interfaces and using 65k is silly, and 1500 can also get you in to big trouble. My work goes on a lot of different hardware / platforms / routers, and to be honest the place I start is 1400 bytes. If you NEED more than 1400 you can start to inch your way up, you can probably go to 1450 and sometimes to 1480'ish? If you need more than that then of course you need to split in to 2 packets, of which there are several obvious ways of doing..

The problem is that you're talking about creating a data packet and writing it out via TCP, but of course there's header data tacked on and so forth, so you have "baggage" that puts you to 1500 or beyond.. and also a lot of hardware has lower limits.

If you "push it" you can get some really weird things going on. Truncated data, obviously, or dropped data I've seen rarely. Corrupted data also rarely but certainly does happen.

You can generate a stack trace and use the informations in the StackTraceElements.

For example an utility class can return you the calling class name :

public class KDebug {
    public static String getCallerClassName() { 
        StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
        for (int i=1; i<stElements.length; i++) {
            StackTraceElement ste = stElements[i];
            if (!ste.getClassName().equals(KDebug.class.getName()) && ste.getClassName().indexOf("java.lang.Thread")!=0) {
                return ste.getClassName();
            }
        }
        return null;
     }
}

If you call KDebug.getCallerClassName() from bar(), you'll get "foo".

Now supposing you want to know the class of the method calling bar (which is more interesting and maybe what you really wanted). You could use this method :

public static String getCallerCallerClassName() { 
    StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
    String callerClassName = null;
    for (int i=1; i<stElements.length; i++) {
        StackTraceElement ste = stElements[i];
        if (!ste.getClassName().equals(KDebug.class.getName())&& ste.getClassName().indexOf("java.lang.Thread")!=0) {
            if (callerClassName==null) {
                callerClassName = ste.getClassName();
            } else if (!callerClassName.equals(ste.getClassName())) {
                return ste.getClassName();
            }
        }
    }
    return null;
 }

Is that for debugging ? If not, there may be a better solution to your problem.

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!

This is my working example:

'               This macro is designed to reset all formatting rules to default.

Quick way:

list(set(a).intersection(set(b)))

$argv[0]; // the script name
$argv[1]; // the first parameter
$argv[2]; // the second parameter

If you want to all the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:

<?php
if ($_GET) {
    $argument1 = $_GET['argument1'];
    $argument2 = $_GET['argument2'];
} else {
    $argument1 = $argv[1];
    $argument2 = $argv[2];
}
?>

To call from command line chmod 755 /var/www/webroot/index.php and use

/usr/bin/php /var/www/webroot/index.php arg1 arg2

To call from the browser, use

http://www.mydomain.com/index.php?argument1=arg1&argument2=arg2

I'm not sure how efficient it is memory-wise, but my first approach would be using a Scanner as it is incredibly easy to use:

File file = new File("/path/to/my/file.txt");
Scanner input = new Scanner(file);

while(input.hasNext()) {
    String nextToken = input.next();
    //or to process line by line
    String nextLine = input.nextLine();
}

input.close();

Check the API for how to alter the delimiter it uses to split tokens.

Your page references a Javascript file at /Client/public/core.js.

This file probably can't be found, producing either the website's frontpage or an HTML error page instead. This is a pretty common issue for eg. websites running on an Apache server where paths are redirected by default to index.php.

If that's the case, make sure you replace /Client/public/core.js in your script tag <script type="text/javascript" src="/Client/public/core.js"></script> with the correct file path or put the missing file core.js at location /Client/public/ to fix your error!

If you do already find a file named core.js at /Client/public/ and the browser still produces a HTML page instead, check the permissions for folder and file. Either of these might be lacking the proper permissions.

Use the -ExpandProperty flag of Select-Object

$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority

Update to answer the other question:

Note that you can as well just access the property:

$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

So to get multiple of these into variables:

$var=Get-WSManInstance -enumerate wmicimv2/win32_process
   $prio = $var.Priority
   $pid = $var.ProcessID

Are you missing the 'SET' statement when assigning to your variables in the IF .. ELSE block?

Change your config.php:

$config['sess_use_database'] = TRUE;

To:

$config['sess_use_database'] = FALSE;

It works for me.

It is indeed a key conflict. When concatenating arrays, duplicate keys are not overwritten.

Instead you must use array_merge()

$array = array_merge(array('Item 1'), array('Item 2'));

Updating:

Using adb shell input:

Insert text:

adb shell input text "insert%syour%stext%shere"

(obs: %s means SPACE)

..

Event codes:

adb shell input keyevent 82

(82 ---> MENU_BUTTON)

"For more keyevents codes see list below"

..

Tap X,Y position:

adb shell input tap 500 1450

To find the exact X,Y position you want to Tap go to:

Settings > Developer Options > Check the option POINTER SLOCATION

..

Swipe X1 Y1 X2 Y2 [duration(ms)]:

adb shell input swipe 100 500 100 1450 100

in this example X1=100, Y1=500, X2=100, Y2=1450, Duration = 100ms

..

LongPress X Y:

adb shell input swipe 100 500 100 500 250

we utilise the same command for a swipe to emulate a long press

in this example X=100, Y=500, Duration = 250ms

Follow up answer to help anyone doing this with the VS docker integration. I needed to change to port 8080 to run using the "flexible" environment in google appengine.

You'll need the following in your Dockerfile:

ENV ASPNETCORE_URLS=http://+:8080
EXPOSE 8080

and you'll need to modify the port in docker-compose.yml as well:

    ports:
      - "8080"

To see all keys of Jsonobject use this

    String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";
    JSONObject obj = new JSONObject(JSON);
    Iterator iterator = obj.keys();
    String key = null;
    while (iterator.hasNext()) {
        key = (String) iterator.next();
        System.out.pritnln(key);
    } 

The same instance for SP2010; the Links List webpart will not automatically open in a new window, rather user must manually rt click Link object and select Open in New Window.

The add/ insert Link option withkin SP2010 will allow a user to manually configure the link to open in a new window.

Maybe SP2012 release will adrress this...

"svn co --username=yourUserName --password=yourpassword http://path-to-your-svn"

Worked for me when on another user account. You will be prompted to enter username/password again though. You need to login like the above once and you are all set for the subsequent times(Unless you restart your machine).

Using this function you can get Image Bitmap. Just pass image url

 public Bitmap getBitmapFromURL(String strURL) {
      try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
      } catch (IOException e) {
        e.printStackTrace();
        return null;
      }
 }

Many answers using external programs, which is not really using Bash.

If you know you will have Bash4 available you should really just use the ${VAR,,} notation (it is easy and cool). For Bash before 4 (My Mac still uses Bash 3.2 for example). I used the corrected version of @ghostdog74 's answer to create a more portable version.

One you can call lowercase 'my STRING' and get a lowercase version. I read comments about setting the result to a var, but that is not really portable in Bash, since we can't return strings. Printing it is the best solution. Easy to capture with something like var="$(lowercase $str)".

How this works

The way this works is by getting the ASCII integer representation of each char with printf and then adding 32 if upper-to->lower, or subtracting 32 if lower-to->upper. Then use printf again to convert the number back to a char. From 'A' -to-> 'a' we have a difference of 32 chars.

Using printf to explain:

$ printf "%d\n" "'a"
97
$ printf "%d\n" "'A"
65

97 - 65 = 32

And this is the working version with examples.
Please note the comments in the code, as they explain a lot of stuff:

#!/bin/bash

# lowerupper.sh

# Prints the lowercase version of a char
lowercaseChar(){
    case "$1" in
        [A-Z])
            n=$(printf "%d" "'$1")
            n=$((n+32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the lowercase version of a sequence of strings
lowercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        lowercaseChar "$ch"
    done
}

# Prints the uppercase version of a char
uppercaseChar(){
    case "$1" in
        [a-z])
            n=$(printf "%d" "'$1")
            n=$((n-32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the uppercase version of a sequence of strings
uppercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        uppercaseChar "$ch"
    done
}

# The functions will not add a new line, so use echo or
# append it if you want a new line after printing

# Printing stuff directly
lowercase "I AM the Walrus!"$'\n'
uppercase "I AM the Walrus!"$'\n'

echo "----------"

# Printing a var
str="A StRing WITH mixed sTUFF!"
lowercase "$str"$'\n'
uppercase "$str"$'\n'

echo "----------"

# Not quoting the var should also work, 
# since we use "$@" inside the functions
lowercase $str$'\n'
uppercase $str$'\n'

echo "----------"

# Assigning to a var
myLowerVar="$(lowercase $str)"
myUpperVar="$(uppercase $str)"
echo "myLowerVar: $myLowerVar"
echo "myUpperVar: $myUpperVar"

echo "----------"

# You can even do stuff like
if [[ 'option 2' = "$(lowercase 'OPTION 2')" ]]; then
    echo "Fine! All the same!"
else
    echo "Ops! Not the same!"
fi

exit 0

And the results after running this:

$ ./lowerupper.sh 
i am the walrus!
I AM THE WALRUS!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
myLowerVar: a string with mixed stuff!
myUpperVar: A STRING WITH MIXED STUFF!
----------
Fine! All the same!

This should only work for ASCII characters though.

For me it is fine, since I know I will only pass ASCII chars to it.
I am using this for some case-insensitive CLI options, for example.

Here is how you can use Contains to achieve what you want:

buildingStatus.Select(item => item.GetCharValue()).Contains(v.Status) this will return a Boolean value.

Giving my response just in case if anybody struggling with this issue.

1. You might need to verify that the server.root configuration in "/etc/ngnx/sites-available/domain" matching with your sites.to config in "Homestead.yaml".

2. If its not matching then change it and restart the webserver with "sudo service nginx restart"

3. And still things are not working then allow write permission for the "YOURSITE/app/storage" folder as "chmod -R 777 app/storage"

Be sure to check browser support for the html5 history API:

  if(window.history && window.history.pushState){
    $locationProvider.html5Mode(true);
  }

You can simply import the data from the source file, read it, and save what you want to append to a variable. Then open the destination file, assign the list data inside to a new variable (presumably this will all be valid JSON), then use the 'append' function on this list variable and append the first variable to it. Viola, you have appended to the JSON list. Now just overwrite your destination file with the newly appended list (as JSON).

The 'a' mode in your 'open' function will not work here because it will just tack everything on to the end of the file, which will make it non-valid JSON format.

I wish AngularJS had a built in confirmation dialog. Often, it is nicer to have a customized dialog than using the built in browser one.

I briefly used the twitter bootstrap until it was discontinued with version 6. I looked around for alternatives, but the ones I found were complicated. I decided to try the JQuery UI one.

Here is my sample that I call when I am about to remove something from ng-grid;

    // Define the Dialog and its properties.
    $("<div>Are you sure?</div>").dialog({
        resizable: false,
        modal: true,
        title: "Modal",
        height: 150,
        width: 400,
        buttons: {
            "Yes": function () {
                $(this).dialog('close');
                //proceed with delete...
                /*commented out but left in to show how I am using it in angular
                var index = $scope.myData.indexOf(row.entity);

                $http['delete']('/EPContacts.svc/json/' + $scope.myData[row.rowIndex].RecordID).success(function () { console.log("groovy baby"); });

                $scope.gridOptions.selectItem(index, false);
                $scope.myData.splice(index, 1);
                */
            },
            "No": function () {
                $(this).dialog('close');
                return;
            }
        }
    });

I hope this helps someone. I was pulling my hair out when I needed to upgrade ui-bootstrap-tpls.js but it broke my existing dialog. I came into work this morning, tried a few things and then realized I was over complicating.

I would use lambda function on a Series of a DataFrame like this:

f = lambda x: 0 if x>100 else 1
df['my_column'] = df['my_column'].map(f)

I do not assert that this is an efficient way, but it works fine.

Run the following code:

du -sh /var/log/mysql

Perhaps mysql binary logs filled the memory, If so, follow the removal of old logs and restart the server. Also add in my.cnf:

expire_logs_days = 3

You can do it without dealing with encoding by using BlockCopy:

char[] chars = new char[bytes.Length / sizeof(char)];
System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
string str = new string(chars);

You want to feed the create.sql into sqlite3 from the shell, not from inside SQLite itself:

$ sqlite3 auction.db < create.sql

SQLite's version of SQL doesn't understand < for files, your shell does.

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:

• Add a pause to the batch file so that you can see what is happening before it exits.
  1. Right click on one of the .bat files and select "edit". This will open the file in notepad.
  2. Go to the very end of the file and add a new line by pressing "enter".
  3. type pause.
  4. Save the file.
  5. Run the file again using the same method you did before.

- OR -

• Run the batch file from a static command prompt so the window does not close.
  1. In the folder where the .bat files are located, hold down the "shift" key and right click in the white space.
  2. Select "Open Command Window Here".
  3. You will now see a new command prompt. Type in the name of the batch file and press enter.

Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.

Use this.dispose for current window to close and next_window.setVisible(true) to show next window behind button property ActionPerformed , Example is shown below in pic for your help.

Because by default jQuery serializes objects passed as the data parameter to $.ajax. It uses $.param to convert the data to a query string.

From the jQuery docs for $.ajax:

[the data argument] is converted to a query string, if not already a string

If you want to send JSON, you'll have to encode it yourself:

data: JSON.stringify(arr);

Note that JSON.stringify is only present in modern browsers. For legacy support, look into json2.js

Update your pip first:

pip install --upgrade pip

for Python 3:

pip3 install --upgrade pip

When working with graphical user interfaces, you need to remember that drawing on a pane is done in the Java AWT/Swing event queue. You can't just use the Graphics object outside the paint()/paintComponent()/etc. methods.

However, you can use a technique called "Frame buffering". Basically, you need to have a BufferedImage and draw directly on it (see it's createGraphics() method; that graphics context you can keep and reuse for multiple operations on a same BufferedImage instance, no need to recreate it all the time, only when creating a new instance). Then, in your JPanel's paintComponent(), you simply need to draw the BufferedImage instance unto the JPanel. Using this technique, you can perform zoom, translation and rotation operations quite easily through affine transformations.

You can use this way...

grep -P '^\s$' file

• -P is used for Perl regular expressions (an extension to POSIX grep).
• \s match the white space characters; if followed by *, it matches an empty line also.
• ^ matches the beginning of the line. $ matches the end of the line.

This error happened to me because I had @@model instead of @model... copy & paste error in my case. Changing to @model fixed it for me.

The example in Liam's answer saves the file as string in a single line. I prefer to add formatting. Someone in the future may want to change some value manually in the file. If you add formatting it's easier to do so.

The following adds basic JSON indentation:

 string json = JsonConvert.SerializeObject(_data.ToArray(), Formatting.Indented);

If you're changing the prototype of the built-in 'function' object it's possible you're running into a browser bug or race condition by modifying a fundamental built-in object.

Test it in multiple browsers to find out.

>/dev/null stops cron from sending mails.

actually to my mind it's better to make php script itself to care about it's logging rather than just outputting something to cron

I won't address the READ UNCOMMITTED argument, just your original question.

Yes, you need WITH(NOLOCK) on each table of the join. No, your queries are not the same.

Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK) hint on it.

file type can be checked in other ways also. I believe this is the easiest way to check the uploaded file type.. if u are dealing with an image file then go for the following code. if you are dealing with a video file then replace the image check with a video check in the if block.. have fun

     $img_up = $_FILES['video_file']['type'];
$img_up_type = explode("/", $img_up);
$img_up_type_firstpart = $img_up_type[0];

if($img_up_type_firstpart == "image") { // image is the image file type, you can deal with video if you need to check video file type
/* do your logical code */
}

All of the preg_replace() solutions above have issues of single line comments, conditional comments and other pitfalls. I'd recommend taking advantage of the well-tested Minify project rather than creating your own regex from scratch.

In my case I place the following code at the top of a PHP page to minify it:

function sanitize_output($buffer) {
    require_once('min/lib/Minify/HTML.php');
    require_once('min/lib/Minify/CSS.php');
    require_once('min/lib/JSMin.php');
    $buffer = Minify_HTML::minify($buffer, array(
        'cssMinifier' => array('Minify_CSS', 'minify'),
        'jsMinifier' => array('JSMin', 'minify')
    ));
    return $buffer;
}
ob_start('sanitize_output');

I write below code to remove the blank value in the array string.

string[] test={"1","","2","","3"};
test= test.Except(new List<string> { string.Empty }).ToArray();

I tried to create an online concept of CSS/HTML analyzer tool:

http://www.motobit.com/util/base64/css-images-to-base64.asp

It can:

• Download and parse HTML/CSS files, extract href/src/url elements
• Detect compression (gzip) and size data on the URL
• Compare original data size, base64 data size and gzipped base64 data size
• Convert the URL (image, font, css, ...) to a base64 data URI scheme.
• Count number of requests which can be spared by Data URIs

Comments/suggestions are welcome.

This defines what shell (command interpreter) you are using for interpreting/running your script. Each shell is slightly different in the way it interacts with the user and executes scripts (programs).

When you type in a command at the Unix prompt, you are interacting with the shell.

E.g., #!/bin/csh refers to the C-shell, /bin/tcsh the t-shell, /bin/bash the bash shell, etc.

You can tell which interactive shell you are using the

 echo $SHELL

command, or alternatively

 env | grep -i shell

You can change your command shell with the chsh command.

Each has a slightly different command set and way of assigning variables and its own set of programming constructs. For instance the if-else statement with bash looks different that the one in the C-shell.

This page might be of interest as it "translates" between bash and tcsh commands/syntax.

Using the directive in the shell script allows you to run programs using a different shell. For instance I use the tcsh shell interactively, but often run bash scripts using /bin/bash in the script file.

Aside:

This concept extends to other scripts too. For instance if you program in Python you'd put

 #!/usr/bin/python

at the top of your Python program

You can access mySQL in command line just by typing:

C:\www\mysql\bin> mysql -u root -p

After which you can type sql commands normally such as:

mysql> SHOW DATABASES;

Here, I am assuming you mySQL installation directory is C:\www\mysql.

You can also reference the obj once you are inside the function instead of this.

var obj = {
    key1: "it",
    key2: function(){return obj.key1 + " works!"}
};
alert(obj.key2());

Use HttpServerUtility.UrlEncode

I made an adaptation of the Microsoft way, where I override the ListView control to make a SortableListView:

public partial class SortableListView : ListView
    {        
        private GridViewColumnHeader lastHeaderClicked = null;
        private ListSortDirection lastDirection = ListSortDirection.Ascending;       

        public void GridViewColumnHeaderClicked(GridViewColumnHeader clickedHeader)
        {
            ListSortDirection direction;

            if (clickedHeader != null)
            {
                if (clickedHeader.Role != GridViewColumnHeaderRole.Padding)
                {
                    if (clickedHeader != lastHeaderClicked)
                    {
                        direction = ListSortDirection.Ascending;
                    }
                    else
                    {
                        if (lastDirection == ListSortDirection.Ascending)
                        {
                            direction = ListSortDirection.Descending;
                        }
                        else
                        {
                            direction = ListSortDirection.Ascending;
                        }
                    }

                    string sortString = ((Binding)clickedHeader.Column.DisplayMemberBinding).Path.Path;

                    Sort(sortString, direction);

                    lastHeaderClicked = clickedHeader;
                    lastDirection = direction;
                }
            }
        }

        private void Sort(string sortBy, ListSortDirection direction)
        {
            ICollectionView dataView = CollectionViewSource.GetDefaultView(this.ItemsSource != null ? this.ItemsSource : this.Items);

            dataView.SortDescriptions.Clear();
            SortDescription sD = new SortDescription(sortBy, direction);
            dataView.SortDescriptions.Add(sD);
            dataView.Refresh();
        }
    }

The line ((Binding)clickedHeader.Column.DisplayMemberBinding).Path.Path bit handles the cases where your column names are not the same as their binding paths, which the Microsoft method does not do.

I wanted to intercept the GridViewColumnHeader.Click event so that I wouldn't have to think about it anymore, but I couldn't find a way to to do. As a result I add the following in XAML for every SortableListView:

GridViewColumnHeader.Click="SortableListViewColumnHeaderClicked"

And then on any Window that contains any number of SortableListViews, just add the following code:

private void SortableListViewColumnHeaderClicked(object sender, RoutedEventArgs e)
        {
            ((Controls.SortableListView)sender).GridViewColumnHeaderClicked(e.OriginalSource as GridViewColumnHeader);
        }

Where Controls is just the XAML ID for the namespace in which you made the SortableListView control.

So, this does prevent code duplication on the sorting side, you just need to remember to handle the event as above.

@dhanushka's approach showed the most promise but I wanted to play around in Python so went ahead and translated it for fun:

import cv2
import numpy as np
from cv2 import boundingRect, countNonZero, cvtColor, drawContours, findContours, getStructuringElement, imread, morphologyEx, pyrDown, rectangle, threshold

large = imread(image_path)
# downsample and use it for processing
rgb = pyrDown(large)
# apply grayscale
small = cvtColor(rgb, cv2.COLOR_BGR2GRAY)
# morphological gradient
morph_kernel = getStructuringElement(cv2.MORPH_ELLIPSE, (3, 3))
grad = morphologyEx(small, cv2.MORPH_GRADIENT, morph_kernel)
# binarize
_, bw = threshold(src=grad, thresh=0, maxval=255, type=cv2.THRESH_BINARY+cv2.THRESH_OTSU)
morph_kernel = getStructuringElement(cv2.MORPH_RECT, (9, 1))
# connect horizontally oriented regions
connected = morphologyEx(bw, cv2.MORPH_CLOSE, morph_kernel)
mask = np.zeros(bw.shape, np.uint8)
# find contours
im2, contours, hierarchy = findContours(connected, cv2.RETR_CCOMP, cv2.CHAIN_APPROX_SIMPLE)
# filter contours
for idx in range(0, len(hierarchy[0])):
    rect = x, y, rect_width, rect_height = boundingRect(contours[idx])
    # fill the contour
    mask = drawContours(mask, contours, idx, (255, 255, 2555), cv2.FILLED)
    # ratio of non-zero pixels in the filled region
    r = float(countNonZero(mask)) / (rect_width * rect_height)
    if r > 0.45 and rect_height > 8 and rect_width > 8:
        rgb = rectangle(rgb, (x, y+rect_height), (x+rect_width, y), (0,255,0),3)

Now to display the image:

from PIL import Image
Image.fromarray(rgb).show()

Not the most Pythonic of scripts but I tried to resemble the original C++ code as closely as possible for readers to follow.

It works almost as well as the original. I'll be happy to read suggestions how it could be improved/fixed to resemble the original results fully.

I wrote a directive you can use to bind an ng-model to any expression you want. Whenever the expression changes the model is set to the new value.

 module.directive('boundModel', function() {
      return {
        require: 'ngModel',
        link: function(scope, elem, attrs, ngModel) {
          var boundModel$watcher = scope.$watch(attrs.boundModel, function(newValue, oldValue) {
            if(newValue != oldValue) {
              ngModel.$setViewValue(newValue);
              ngModel.$render();
            }
          });

          // When $destroy is fired stop watching the change.
          // If you don't, and you come back on your state
          // you'll have two watcher watching the same properties
          scope.$on('$destroy', function() {
              boundModel$watcher();
          });
        }
    });

You can use it in your templates like this:

 <li>Total<input type="text" ng-model="total" bound-model="one * two"></li>      

You can use this small library: https://github.com/ledfusion/php-rest-curl

Making a call is as simple as:

// GET
$result = RestCurl::get($URL, array('id' => 12345678));

// POST
$result = RestCurl::post($URL, array('name' => 'John'));

// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));

// DELETE
$result = RestCurl::delete($URL); 

And for the $result variable:

• $result['status'] is the HTTP response code
• $result['data'] an array with the JSON response parsed
• $result['header'] a string with the response headers

Hope it helps

The following library can also be used for HTML escaping in Java: unbescape.

HTML can be unescaped this way:

final String unescapedText = HtmlEscape.unescapeHtml(escapedText); 

HTML CODE

        <input type="text" onkeypress="checkPass();" name="password" class="form-control" id="password" placeholder="Password" required>

        <input type="text" onkeypress="checkPass();" name="rpassword" class="form-control" id="rpassword" placeholder="Retype Password" required>

JS CODE

function checkPass(){
         var pass  = document.getElementById("password").value;
         var rpass  = document.getElementById("rpassword").value;
        if(pass != rpass){
            document.getElementById("submit").disabled = true;
            $('.missmatch').html("Entered Password is not matching!! Try Again");
        }else{
            $('.missmatch').html("");
            document.getElementById("submit").disabled = false;
        }
}

You don't need ng-checked when you use ng-model. If you're performing CRUD on your HTML Form, just create a model for CREATE mode that is consistent with your EDIT mode during the data-binding:

CREATE Mode: Model with default values only

$scope.dataModel = {
   isItemSelected: true,
   isApproved: true,
   somethingElse: "Your default value"
}

EDIT Mode: Model from database

$scope.dataModel = getFromDatabaseWithSameStructure()

Then whether EDIT or CREATE mode, you can consistently make use of your ng-model to sync with your database.

Can you give this a try,

return View::make("user/regprofile", compact('students')); OR
return View::make("user/regprofile")->with(array('students'=>$students));

While, you can set multiple variables something like this,

$instructors="";
$instituitions="";

$compactData=array('students', 'instructors', 'instituitions');
$data=array('students'=>$students, 'instructors'=>$instructors, 'instituitions'=>$instituitions);

return View::make("user/regprofile", compact($compactData));
return View::make("user/regprofile")->with($data);

In my case I was miscalculating the Content-Length that I advertised in the header. I was serving Range-Requests for files and I mistakenly published the filesize in Content-Length.

I fixed the problem by setting Content-Length to the actual range that I was sending back to the browser.

So in case I am answering to a normal request I set the Content-Length to the filesize. In case I am answering to a range-request I set the Content-Length to the actualy length of the requested range.

for (Map.Entry<String, String> item : hashMap.entrySet()) {
    String key = item.getKey();
    String value = item.getValue();
}

Solution for Android Studio 2.3.3 on MacOS 10.12.6

Start Android Studios with more heap memory:

export JAVA_OPTS="-Xms6144m -Xmx6144m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"
open -a /Applications/Android\ Studio.app

The accepted answer (the one with the green check mark) has an issue.

The problem:

var result = Lists.Repeated(new MyType(), sizeOfList);
// each item in the list references the same MyType() object
// if you edit item 1 in the list, you are also editing item 2 in the list

I recommend changing the line above to perform a copy of the object. There are many different articles about that:

• String.MemberwiseClone() method called through reflection doesn't work, why?
• https://code.msdn.microsoft.com/windowsdesktop/CSDeepCloneObject-8a53311e

If you want to initialize every item in your list with the default constructor, rather than NULL, then add the following method:

public static List<T> RepeatedDefaultInstance<T>(int count)
    {
        List<T> ret = new List<T>(count);
        for (var i = 0; i < count; i++)
        {
            ret.Add((T)Activator.CreateInstance(typeof(T)));
        }
        return ret;
    }

This selects all DIVs with an ID containing 'foo' and that are visible

$("div:visible[id*='foo']");

Python 2.6 added a new strftime/strptime macro %f, which does microseconds. Not sure if this is documented anywhere. But if you're using 2.6 or 3.0, you can do this:

time.strptime('30/03/09 16:31:32.123', '%d/%m/%y %H:%M:%S.%f')

Edit: I never really work with the time module, so I didn't notice this at first, but it appears that time.struct_time doesn't actually store milliseconds/microseconds. You may be better off using datetime, like this:

>>> from datetime import datetime
>>> a = datetime.strptime('30/03/09 16:31:32.123', '%d/%m/%y %H:%M:%S.%f')
>>> a.microsecond
123000

I believe you can use the append method

bigdata = data1.append(data2, ignore_index=True)

to keep their indexes just dont use the ignore_index keyword ...

You need to set the g flag to replace globally:

date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')

Otherwise only the first occurrence will be replaced.

best bet is targeting features not devices unless you have to, bootstrap do well and you can extend on their breakpoints, for instance targeting pixel density and larger screens above 1920

days, hours, minutes = td.days, td.seconds // 3600, td.seconds // 60 % 60

As for DST, I think the best thing is to convert both datetime objects to seconds. This way the system calculates DST for you.

>>> m13 = datetime(2010, 3, 13, 8, 0, 0)  # 2010 March 13 8:00 AM
>>> m14 = datetime(2010, 3, 14, 8, 0, 0)  # DST starts on this day, in my time zone
>>> mktime(m14.timetuple()) - mktime(m13.timetuple())     # difference in seconds
82800.0
>>> _/3600                                                # convert to hours
23.0

On Windows open the file php.ini and make this changes:

Remove the comment and point to the ext directory

; extension_dir = "./" -> extension_dir = "C:/Php/ext"

Remove the comment of this extensions

• extension=php_mbstring.dll
• extension=php_mysqli.dll

Restart apache service

httpd -k restart

When i use apt install python3-pip, i get a lot of packages need install, but i donot need them. So, i DO like this:

python3 get-pip.py
rm -f get-pip.py

Note from Michael 12/28/2011 - I have changed my accept from this (rubytheracer) to above (nodejs) as therubyracer has code size issues. Heroku now strongly discourage it. It will 'work' but may have size/performance issues.

If you add a runtime, such as therubyracer to your Gemfile and run bundle then try and start the server it should work.

gem 'therubyracer'

A javascript runtime is required for compiling coffeescript and also for uglifier.

Update, 12/12/2011: Some folks found issues with rubytheracer (I think it was mostly code size). They found execjs (or nodejs) worked just as well (if not better) and were much smaller.

n.b. Coffeescript became a standard for 3.1+

You could use

var firstNames: [String] = []

At a former employer we had a unique column that contained a random uuid. We got a collision the first week after it was deployed. Sure, the odds are low but they aren't zero. That is why Log4j 2 contains UuidUtil.getTimeBasedUuid. It will generate a UUID that is unique for 8,925 years so long as you don't generate more than 10,000 UUIDs/millisecond on a single server.

This should work:

string url = "http://example.com/file?a=1&b=2&c=string%20param";
string querystring = url.Substring(url.IndexOf('?'));
System.Collections.Specialized.NameValueCollection parameters = 
   System.Web.HttpUtility.ParseQueryString(querystring);

According to MSDN. Not the exact collectiontype you are looking for, but nevertheless useful.

Edit: Apparently, if you supply the complete url to ParseQueryString it will add 'http://example.com/file?a' as the first key of the collection. Since that is probably not what you want, I added the substring to get only the relevant part of the url.

I have found that in general it is recommended to preprocess scripts at compile time and bundle them in one (or very few) packages with the require being rewritten to some "lightweight shim" also at compile time.

I've Googled out following "new" tools that should be able to do it

• http://mixu.net/gluejs/
• https://github.com/jrburke/almond
• https://github.com/component/builder2.js

And the already mentioned browserify should also fit quite well - http://esa-matti.suuronen.org/blog/2013/04/15/asynchronous-module-loading-with-browserify/

What are the module systems all about?

• Older Stack Overflow explanation - Relation between CommonJS, AMD and RequireJS?

• Detailed discussion of various module frameworks and the require() they need is in Addy Osmani - Writing Modular JavaScript With AMD, CommonJS & ES Harmony

With JPA 2.1 you should be able to do it.

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Index;
import javax.persistence.Table;

@Entity
@Table(name = "region",
       indexes = {@Index(name = "my_index_name",  columnList="iso_code", unique = true),
                  @Index(name = "my_index_name2", columnList="name",     unique = false)})
public class Region{

    @Column(name = "iso_code", nullable = false)
    private String isoCode;

    @Column(name = "name", nullable = false)
    private String name;

} 

Update: If you ever need to create and index with two or more columns you may use commas. For example:

@Entity
@Table(name    = "company__activity", 
       indexes = {@Index(name = "i_company_activity", columnList = "activity_id,company_id")})
public class CompanyActivity{

In Python 3, urllib2 was replaced by two in-built modules named urllib.request and urllib.error

Adapted from source

So replace this:

import urllib2

With this:

import urllib.request as urllib2

For example, if you want to make the color of "text" green, just type:

<font color='green'>text</font>

1-Delete the migration file. 2-connect to your database and drop the table created by the migration. 3-recreate the file of the migration with the the right sql.

Tiny addition to this very old thread..

If your'e evaluating an expression inside a for/while loop with a ternary operator, and want to continue or break as a result - you're gonna have a problem because both continue&break aren't expressions, they're statements without any value.

This will produce Uncaught SyntaxError: Unexpected token continue

 for (const item of myArray) {
      item.value ? break : continue;
 }

If you really want a one-liner that returns a statement, you can use this instead:

  for (const item of myArray) {
      if (item.value) break; else continue;
  }

• P.S - This code might raise some eyebrows. Just saying.. :)

I am not familiar with JXL and but we use POI. POI is well maintained and can handle both the binary .xls format and the new xml based format that was introduced in Office 2007.

CSV files are not excel files, they are text based files, so these libraries don't read them. You will need to parse out a CSV file yourself. I am not aware of any CSV file libraries, but I haven't looked either.

In my case CORS error was happening only in POST requests with file attachments other than small files.

After many wasted hours we found out request was blocked for users who were using Kaspersky Total Control.

It's possible that other antivirus or firewall software may cause similar problems. Kaspersky run some security tests for requests, but omits them for websites with SSL EV certificate, so obtaining such certificate should resolve this issue properly.

Disabling protection for your domain is a bit tricky, so here are required steps (as for December 2020): Settings -> Network Settings -> Manage exclusions -> Add -> your domain -> Save

The good thing is you can detect such blocked request. The error is empty – it doesn't have status and response. This way you can assume it was blocked by third party software and show some info.

To link from a page to another section of the page, I navigate through the page depending on the page's location to the other, at the URL bar, and add the #id. So what I mean;

<a href = "../#the_part_that_you_want">This takes you #the_part_that_you_want at the page before</a>

The following example creates a file chooser and displays it as first an open-file dialog and then as a save-file dialog:

String filename = File.separator+"tmp";
JFileChooser fc = new JFileChooser(new File(filename));

// Show open dialog; this method does not return until the dialog is closed
fc.showOpenDialog(frame);
File selFile = fc.getSelectedFile();

// Show save dialog; this method does not return until the dialog is closed
fc.showSaveDialog(frame);
selFile = fc.getSelectedFile();

Here is a more elaborate example that creates two buttons that create and show file chooser dialogs.

// This action creates and shows a modal open-file dialog.
public class OpenFileAction extends AbstractAction {
    JFrame frame;
    JFileChooser chooser;

    OpenFileAction(JFrame frame, JFileChooser chooser) {
        super("Open...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showOpenDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

// This action creates and shows a modal save-file dialog.
public class SaveFileAction extends AbstractAction {
    JFileChooser chooser;
    JFrame frame;

    SaveFileAction(JFrame frame, JFileChooser chooser) {
        super("Save As...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showSaveDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

int i = 1;
Test val = static_cast<Test>(i);

TryGetValue will already assign the default value for the type to the dictionary, so you can just use:

dictionary.TryGetValue(key, out value);

and just ignore the return value. However, that really will just return default(TValue), not some custom default value (nor, more usefully, the result of executing a delegate). There's nothing more powerful built into the framework. I would suggest two extension methods:

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary, 
     TKey key,
     TValue defaultValue)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value : defaultValue;
}

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary,
     TKey key,
     Func<TValue> defaultValueProvider)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value
         : defaultValueProvider();
}

(You may want to put argument checking in, of course :)

I think that a good idea is to use mb_stpos:

$haystack = 'How are you?';
$needle = 'are';

if (mb_strpos($haystack, $needle) !== false) {

    echo 'true';
}

Because this solution is case sensitive and safe for all Unicode characters.

But you can also do it like this (sauch response was not yet):

if (count(explode($needle, $haystack)) > 1) {

    echo 'true';
}

This solution is also case sensitive and safe for Unicode characters.

In addition you do not use the negation in the expression, which increases the readability of the code.

Here is other solution using function:

function isContainsStr($haystack, $needle) {

    return count(explode($needle, $haystack)) > 1;
}

if (isContainsStr($haystack, $needle)) {

    echo 'true';
}

Yes, I think hashing the file would be the best way if you have to compare several files and store hashes for later comparison. As hash can clash, a byte-by-byte comparison may be done depending on the use case.

Generally byte-by-byte comparison would be sufficient and efficient, which filecmp module already does + other things too.

See http://docs.python.org/library/filecmp.html e.g.

>>> import filecmp
>>> filecmp.cmp('file1.txt', 'file1.txt')
True
>>> filecmp.cmp('file1.txt', 'file2.txt')
False

Speed consideration: Usually if only two files have to be compared, hashing them and comparing them would be slower instead of simple byte-by-byte comparison if done efficiently. e.g. code below tries to time hash vs byte-by-byte

Disclaimer: this is not the best way of timing or comparing two algo. and there is need for improvements but it does give rough idea. If you think it should be improved do tell me I will change it.

import random
import string
import hashlib
import time

def getRandText(N):
    return  "".join([random.choice(string.printable) for i in xrange(N)])

N=1000000
randText1 = getRandText(N)
randText2 = getRandText(N)

def cmpHash(text1, text2):
    hash1 = hashlib.md5()
    hash1.update(text1)
    hash1 = hash1.hexdigest()

    hash2 = hashlib.md5()
    hash2.update(text2)
    hash2 = hash2.hexdigest()

    return  hash1 == hash2

def cmpByteByByte(text1, text2):
    return text1 == text2

for cmpFunc in (cmpHash, cmpByteByByte):
    st = time.time()
    for i in range(10):
        cmpFunc(randText1, randText2)
    print cmpFunc.func_name,time.time()-st

and the output is

cmpHash 0.234999895096
cmpByteByByte 0.0

There can be multiple root causes for this exception. For me, my mockMvc wasn't getting auto-configured. I solved this exception by using @WebMvcTest(MyController.class) at the class level. This annotation will disable full auto-configuration and instead apply only configuration relevant to MVC tests.

An alternative to this is, If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest combined with @AutoConfigureMockMvc rather than @WebMvcTest

In my case, things i had to do is only enabling the Embedded Browser OAuth Login

I like simbu's approach, but I ain't comfortable to use first-child or last-child. Instead I only modify the content of a repeating list-comma class.

.list-comma + .list-comma::before {
    content: ', ';
}

<span class="list-comma" ng-repeat="destination in destinations">
    {{destination.name}}
</span>

You want to look into 'Splash' Screens.

Display another 'Splash' form and wait until the processing is done.

Here is an example on how to do it.

To Convert BEGIN OPENSSH PRIVATE KEY to BEGIN RSA PRIVATE KEY:

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa

Escaping parameters like that is usually source of frustration and feels a lot like a time wasted. I see you're on v2 so I would suggest using a technique that Joel "Jaykul" Bennet blogged about a while ago.

Long story short: you just wrap your string with @' ... '@ :

Start-Process \\server\toto.exe @'
-batch=B -param="sort1;parmtxt='Security ID=1234'"
'@

(Mind that I assumed which quotes are needed, and which things you were attempting to escape.) If you want to work with the output, you may want to add the -NoNewWindow switch.

BTW: this was so important issue that since v3 you can use --% to stop the PowerShell parser from doing anything with your parameters:

\\server\toto.exe --% -batch=b -param="sort1;paramtxt='Security ID=1234'"

... should work fine there (with the same assumption).

The complete binary example is O(ln n) because the search looks like this:

1 2 3 4 5 6 7 8 9 10 11 12

Searching for 4 yields 3 hits: 6, 3 then 4. And log2 12 = 3, which is a good apporximate to how many hits where needed.

At first I was stuck trying to figure out out to "insert" the Guest Additions CD image in Windows because I presumed it was a separate download that I would have to mount or somehow attach to the virtual CD drive. But just going through the Mac VirtualBox Devices menu and picking "Insert Guest Additions CD Image..." seemed to do the trick. Nothing to mount, nothing to "insert".

Elsewhere I found that the Guest Additions update was part of the update package, so I guess the new VB found the new GA CD automatically when Windows went looking. I wish I had known that to start.

Also, it appears that when I installed the Guest Additions on my Linked Base machine, it propagated to the other machines that were based on it. Sweet. Only one installation for multiple "machines".

I still haven't found that documented, but it appears to be the case (probably I'm not looking for the right explanation terms because I don't already know the explanation). How that works should probably be a different thread.

You are mixing razor and aspx syntax,if your view engine is razor just do this:

<button class="btn btn-info" type="button" id="addressSearch"   
          onclick="location.href='@Url.Action("List", "Search")'">

The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.

Also, I didn't understand when the accepted answer said "it defaults to node server.js". I think the documentation clarifies the default behavior:

npm-start

Start a package

Synopsis

npm start [-- <args>]

Description

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

In summary, running npm start could do one of two things:

1. npm start {command_name}: Run an arbitrary command (i.e. if such command is specified in the start property of package.json's scripts object)
2. npm start: Else if no start property exists (or no command_name is passed): Run node server.js, (which may not be appropriate, for example the OP doesn't have server.js; the OP runs nodeapp.js )
3. I said I would list only 2 items, but are other possibilities (i.e. error cases). For example, if there is no package.json in the directory where you run npm start, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'

You just make divs like this:

<div style="width:100px; height: 100px; border:1px solid; overflow:hidden; ">
    <br/>
    <div style="position:inherit; width: 200px; height:200px; background:yellow;">
        <br/>
        <div style="position:absolute; width: 500px; height:50px; background:Pink; z-index: 99;">
            <br/>
        </div>
    </div>
</div>

I hope this code will help you :)

I use

            chartRange = xlWorkSheet.Rows[1];
            chartRange.Font.Bold = true;

to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.

You can call in VBA directly

            ActiveCell.Font.Bold = True

With this code I create a timestamp in the active cell, with bold font and yellow background

           Private Sub Worksheet_SelectionChange(ByVal Target As Range)
               ActiveCell.Value = Now()
               ActiveCell.Font.Bold = True
               ActiveCell.Interior.ColorIndex = 6
           End Sub

Servlet is server side technology which is used to create dynamic web page in web application. Actually servlet is an api which consist of group of classes and interfaces, which has some functionality. When we use Servlet API we can use predefined functionality of servlet classes and interfaces.

Lifecycle of Servlet:

Web container maintains the lifecycle of servlet instance.

1 . Servlet class loaded

2 . Servlet instance created

3 . init() method is invoked

4 . service() method invoked

5 . destroy() method invoked

When request raise by client(browser) then web-container checks whether the servlet is running or not if yes then it invoke the service() method and give the response to browser..

When servlet is not running then web-container follow the following steps..

1. classloader load the servlet class

2. Instantiates the servlet

3. Initializes the servlet

4.invoke the service() method

after serving the request web-container wait for specific time, in this time if request comes then it call only service() method otherwise it call destroy() method..

If you want, you can deactivate this feature in your git core config using

git config core.autocrlf false

But it would be better to just get rid of the warnings using

git config core.autocrlf true

Solution

1. Create new UNIQUE key that is identical to your current PRIMARY key
2. Add new column id is unsigned integer, auto_increment
3. Create primary key on new id column

Bam, immediate 10x+ insert improvement.

for this approach, you will need to add system.IO to your references by adding the next line of code below the other references near the top of the c# file(where the other using ****.** stand).

using System.IO;

this next code contains 2 methods of reading the text, the first will read single lines and stores them in a string variable, the second one reads the whole text and saves it in a string variable(including "\n" (enters))

both should be quite easy to understand and use.

    string pathToFile = "";//to save the location of the selected object
    private void openToolStripMenuItem_Click(object sender, EventArgs e)
    {
        OpenFileDialog theDialog = new OpenFileDialog();
        theDialog.Title = "Open Text File";
        theDialog.Filter = "TXT files|*.txt";
        theDialog.InitialDirectory = @"C:\";
        if (theDialog.ShowDialog() == DialogResult.OK)
        {
            MessageBox.Show(theDialog.FileName.ToString());
            pathToFile = theDialog.FileName;//doesn't need .tostring because .filename returns a string// saves the location of the selected object

        }

        if (File.Exists(pathToFile))// only executes if the file at pathtofile exists//you need to add the using System.IO reference at the top of te code to use this
        {
            //method1
            string firstLine = File.ReadAllLines(pathToFile).Skip(0).Take(1).First();//selects first line of the file
            string secondLine = File.ReadAllLines(pathToFile).Skip(1).Take(1).First();

            //method2
            string text = "";
            using(StreamReader sr =new StreamReader(pathToFile))
            {
                text = sr.ReadToEnd();//all text wil be saved in text enters are also saved
            }
        }
    }

To split the text you can use .Split(" ") and use a loop to put the name back into one string. if you don't want to use .Split() then you could also use foreach and ad an if statement to split it where needed.

to add the data to your class you can use the constructor to add the data like:

  public Employee(int EMPLOYEENUM, string NAME, string ADRESS, double WAGE, double HOURS)
        {
            EmployeeNum = EMPLOYEENUM;
            Name = NAME;
            Address = ADRESS;
            Wage = WAGE;
            Hours = HOURS;
        }

or you can add it using the set by typing .variablename after the name of the instance(if they are public and have a set this will work). to read the data you can use the get by typing .variablename after the name of the instance(if they are public and have a get this will work).

In your HTML it is a good pratice to provide the encoding like using the following meta like this for example:

<meta http-equiv="content-type" content="text/html; charset=utf-8" />

But your warning that you see may be trigged by one of multiple files. it might not be your HTML document. It might be something in a javascript file or css file. if you page is made of up multiples php files included together it may be only 1 of those files.

I dont think this error has anything to do with mootools. you see this message in your firefox console window. not mootools script.

maybe you simply need to re-save your html pages using a code editor that lets you specify the correct character encoding.

use "LEFT"

 select left('Hello World', 5)

or use "SUBSTRING"

 select substring('Hello World', 1, 5)

I found KAsun's answer works better using vw instead of px like so:

<td><div style="width: 10vw" >...............</div></td>

This was the only styling I needed to adjust the column width

Open report in Report designer

Go to View menu -> Report data

Bootstrap 4 provides the Collapse component for that. It's using JavaScript behind the scenes, but you don't have to write any JavaScript yourself.

This feature works for <button> and <a>.

If you use a <button>, you must set the data-toggle and data-target attributes:

<button type="button" data-toggle="collapse" data-target="#collapseExample">
  Toggle
</button>
<div class="collapse" id="collapseExample">
  Lorem ipsum
</div>

If you use a <a>, you must use set href and data-toggle:

<a data-toggle="collapse" href="#collapseExample">
  Toggle
</a>
<div class="collapse" id="collapseExample">
  Lorem ipsum
</div>

Try this:

SELECT left(right(cast(SampleText as nVarchar),LEN(cast(sampleText as nVarchar))-1),LEN(cast(sampleText as nVarchar))-2)
  FROM TableName

$("#commentForm").validate({
    rules: {
     cname : { required : true, minlength: 2 }
    }
});

Should be something like that, I've just typed this up in the editor here so might be a syntax error or two, but you should be able to follow the pattern and the documentation

+(NSString*)date2str:(NSDate*)myNSDateInstance onlyDate:(BOOL)onlyDate{
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    if (onlyDate) {
        [formatter setDateFormat:@"yyyy-MM-dd"];
    }else{
        [formatter setDateFormat: @"yyyy-MM-dd HH:mm:ss"];
    }

    //Optionally for time zone conversions
    //   [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"..."]];

    NSString *stringFromDate = [formatter stringFromDate:myNSDateInstance];
    return stringFromDate;
}

+(NSDate*)str2date:(NSString*)dateStr{
    if ([dateStr isKindOfClass:[NSDate class]]) {
        return (NSDate*)dateStr;
    }

    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"yyyy-MM-dd"];
    NSDate *date = [dateFormat dateFromString:dateStr];
    return date;
}

Updated solution and workaround for SplitDateTime with required=False:

forms.py

from django import forms

class SplitDateTimeJSField(forms.SplitDateTimeField):
    def __init__(self, *args, **kwargs):
        super(SplitDateTimeJSField, self).__init__(*args, **kwargs)
        self.widget.widgets[0].attrs = {'class': 'vDateField'}
        self.widget.widgets[1].attrs = {'class': 'vTimeField'}  


class AnyFormOrModelForm(forms.Form):
    date = forms.DateField(widget=forms.TextInput(attrs={'class':'vDateField'}))
    time = forms.TimeField(widget=forms.TextInput(attrs={'class':'vTimeField'}))
    timestamp = SplitDateTimeJSField(required=False,)

If you want a simple solution you can use this extension of Android's EditText go to this link for more info: https://github.com/scottyab/showhidepasswordedittext

Add this to your build.gradle: implementation 'com.github.scottyab:showhidepasswordedittext:0.8'

Then change your EditText in your XML file.

From: <EditText

To: <com.scottyab.showhidepasswordedittext.ShowHidePasswordEditText

That's all.

Note: You can't see it while in XML Design, try to run it in your Emulator or Physical Device.

Many answers are correct! I want to add that you can easily find your download location with

gradle --info build

like described in https://stackoverflow.com/a/54000767/4471199.

New downloaded artifacts will be shown in stdout:

Downloading https://plugins.gradle.org/m2/org/springframework/boot/spring-boot-parent/2.1.7.RELEASE/spring-boot-parent-2.1.7.RELEASE.pom to /tmp/gradle_download551283009937119777bin

In this case, I used the docker image gradle:5.6.2-jdk12. As you can see, the docker container uses /tmp as download location.

Although this question was posted 10 years ago, I believe that it still needs some improvements. So here is my solution.

$(document).on('propertychange change click keyup input paste', 'selector', function (e) {
    // Do something here
});

The only problem with this solution is, it won't trigger if the value changes from javascript like $('selector').val('some value'). You can fire any event to your selector when you change the value from javascript.

$(selector).val('some value');
// fire event
$(selector).trigger('change');

Not possible through mockito. From their wiki

Why Mockito doesn't mock private methods?

Firstly, we are not dogmatic about mocking private methods. We just don't care about private methods because from the standpoint of testing private methods don't exist. Here are a couple of reasons Mockito doesn't mock private methods:

It requires hacking of classloaders that is never bullet proof and it changes the api (you must use custom test runner, annotate the class, etc.).

It is very easy to work around - just change the visibility of method from private to package-protected (or protected).

It requires me to spend time implementing & maintaining it. And it does not make sense given point #2 and a fact that it is already implemented in different tool (powermock).

Finally... Mocking private methods is a hint that there is something wrong with OO understanding. In OO you want objects (or roles) to collaborate, not methods. Forget about pascal & procedural code. Think in objects.

Easiest way is to open CMD or powershell as administrator and type

set PATH=%PATH%;C:\Python27

This will work, and if you need where statement you can add it as parameter.

class GenericDAOWithJPA<T, ID extends Serializable> {

.......

public List<T> findAll() {
            return entityManager.createQuery("Select t from " + persistentClass.getSimpleName() + " t").getResultList();
    }
}

It doesn't work for me either when there are multiple foreign key tables.
I found that code that works and does everything you try (delete all tables from your database):

DECLARE @Sql NVARCHAR(500) DECLARE @Cursor CURSOR

SET @Cursor = CURSOR FAST_FORWARD FOR
SELECT DISTINCT sql = 'ALTER TABLE [' + tc2.TABLE_SCHEMA + '].[' +  tc2.TABLE_NAME + '] DROP [' + rc1.CONSTRAINT_NAME + '];'
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc1
LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc2 ON tc2.CONSTRAINT_NAME =rc1.CONSTRAINT_NAME

OPEN @Cursor FETCH NEXT FROM @Cursor INTO @Sql

WHILE (@@FETCH_STATUS = 0)
BEGIN
Exec sp_executesql @Sql
FETCH NEXT FROM @Cursor INTO @Sql
END

CLOSE @Cursor DEALLOCATE @Cursor
GO

EXEC sp_MSforeachtable 'DROP TABLE ?'
GO

You can find the post here. It is the post by Groker.

See here for the definitions.

To return a value when using try/catch you can use a temporary variable, e.g.

public static double add(String[] values) {
    double sum = 0.0;
    try {
        int length = values.length;
        double arrayValues[] = new double[length];
        for(int i = 0; i < length; i++) {
            arrayValues[i] = Double.parseDouble(values[i]);
            sum += arrayValues[i];
        }
    } catch(NumberFormatException e) {
        e.printStackTrace();
    } catch(RangeException e) {
        throw e;
    } finally {
        System.out.println("Thank you for using the program!");
    }
    return sum;
}

Else you need to have a return in every execution path (try block or catch block) that has no throw.

Here is a minor improvement to CMS's solution:

if(!String.prototype.startsWith){
    String.prototype.startsWith = function (str) {
        return !this.indexOf(str);
    }
}

"Hello World!".startsWith("He"); // true

 var data = "Hello world";
 var input = 'He';
 data.startsWith(input); // true

Checking whether the function already exists in case a future browser implements it in native code or if it is implemented by another library. For example, the Prototype Library implements this function already.

Using ! is slightly faster and more concise than === 0 though not as readable.

If you're not using the form's own submit method to send information to a server (and are instead doing it using javascript) you can use the name attribute to attach extra information to an input - rather like pairing it with a hidden input value, but looks neater because it's incorporated into the input.

This bit does still currently work in Firefox although I suppose in the future it might not get allowed through.

You can have multiple input fields with the same name value, as long as you aren't planning to submit the old fashioned way.

Integer.toBinaryString() is an in-built method and will do quite well.

I don't know when exactly the tokens expire, but they do, otherwise there wouldn't be an option to give offline permissions.

Anyway, sometimes requiring the user to give offline permissions is an overkill. Depending on your needs, maybe it's enough that the token remains valid as long as the website is opened in the user's browser. For this there may be a simpler solution - relogging the user in periodically using an iframe: facebook auto re-login from cookie php

Worked for me...

Here is an example code that you may use:

$ STR="String;1;2;3"
$ for EACH in `echo "$STR" | grep -o -e "[^;]*"`; do
    echo "Found: \"$EACH\"";
done

grep -o -e "[^;]*" will select anything that is not ';', therefore spliting the string by ';'.

Hope that help.

I suggest creating a new StringBuffer (or even better, StringBuilder) for each iteration. The performance difference is really negligible, but your code will be shorter and simpler.

If you use a CompletableFuture (introduced in Java 8) or a SettableFuture (from Google Guava), you can make your test finish as soon as it's done, rather than waiting a pre-set amount of time. Your test would look something like this:

CompletableFuture<String> future = new CompletableFuture<>();
executorService.submit(new Runnable() {         
    @Override
    public void run() {
        future.complete("Hello World!");                
    }
});
assertEquals("Hello World!", future.get());

For my case, I need to run

sudo nginx -t

It will check if Nginx configuration is correct or not, if not, it will show you which configuration causes the error.

Then you need to go to /etc/nginx/sites-available to fix the broken configuration.

After that, you can restart Nginx without any problem.

sudo systemctl restart nginx

It could be any one of the parameter, not just the file name or alias - for me it was the Key Password.

Taken from Scott Hanselman's Blog:

public static bool IsNumeric(object expression)
{
    if (expression == null)
    return false;

    double number;
    return Double.TryParse( Convert.ToString( expression
                                            , CultureInfo.InvariantCulture)
                          , System.Globalization.NumberStyles.Any
                          , NumberFormatInfo.InvariantInfo
                          , out number);
}

I realize this is somewhat of an older post, but for anyone that comes to this page looking for a similar solution...

http://api.jquery.com/jQuery.getScript/

jQuery.getScript( url, [ success(data, textStatus) ] )

• url - A string containing the URL to which the request is sent.

• success(data, textStatus) - A callback function that is executed if the request succeeds.

$.getScript('ajax/test.js', function() {
  alert('Load was performed.');
});

To answer more precisely to the question:

conda (which is conda for miniconda as for Anaconda) updates all but ONLY within a specific version of a package -> major and minor. That's the paradigm.

In the documentation you will find "NOTE: Conda updates to the highest version in its series, so Python 2.7 updates to the highest available in the 2.x series and 3.6 updates to the highest available in the 3.x series." doc

If Wang does not gives a reproducible example, one can only assist. e.g. is it really the virtual environment he wants to update or could Wang get what he/she wants with

conda update -n ENVIRONMENT --all

*PLEASE read the docs before executing "update --all"! This does not lead to an update of all packages by nature. Because conda tries to resolve the relationship of dependencies between all packages in your environment, this can lead to DOWNGRADED packages without warnings.

If you only want to update almost all, you can create a pin file

echo "conda ==4.0.0" >> ~/miniconda3/envs/py35/conda-meta/pinned
echo "numpy 1.7.*" >> ~/miniconda3/envs/py35/conda-meta/pinned

before running the update. conda issues not pinned

If later on you want to ignore the file in your env for an update, you can do:

conda update --all --no-pin

You should not do update --all. If you need it nevertheless you are saver to test this in a cloned environment.

First step should always be to backup your current specification:

conda list -n py35 --explicit 

(but even so there is not always a link to the source available - like for jupyterlab extensions)

Next you can clone and update:

conda create -n py356 --clone py35

conda activate py356
conda config --set pip_interop_enabled True # for conda>=4.6
conda update --all

conda config

update:

Because the idea of conda is nice but it is not working out very well for complex environments I personally prefer the combination of nix-shell (or lorri) and poetry [as superior pip/conda .-)] (intro poetry2nix).

Alternatively you can use nix and mach-nix (where you only need you requirements file. It resolves and builds environments best.

On Linux / macOS you could use nix like

nix-env -iA nixpkgs.python37

to enter an environment that has e.g. in this case Python3.7 (for sure you can change the version)

or as a very good Python (advanced) environment you can use mach-nix (with nix) like

mach-nix env ./env -r requirements.txt 

(which even supports conda [but currently in beta])

or via api like

nix-shell -p nixFlakes --run "nix run github:davhau/mach-nix#with.ipython.pandas.seaborn.bokeh.scikit-learn "

Finally if you really need to work with packages that are not compatible due to its dependencies, it is possible with technologies like NixOS/nix-pkgs.

There is a css3 solution here if that is acceptable. It supports the graceful degradation approach where css3 isn't supported. you just won't have any transparency.

}

to get the hex equivalent of 80% (CC) take (pct / 100) * 255 and convert to hex.

For Swift 4

func solution(_ A : [Int]) -> Int {
     var positive = A.filter { $0 > 0 }.sorted()
     var x = 1
     for val in positive{
    // if we find a smaller number no need to continue, cause the array is sorted
    if(x < val) {
        return x
    }
    x = val + 1
}
return x

}

Request.Url.Segments.Last()

Another option.

I have the same problem today, stuck on the kb2999226 for over an hour. First, i thought it is because i am using a VM on my local machine. But decided to cancel the installation, then install kb2999226 first, then install the vs2015 community again, it works out much better, the installation move forward and progressing. thx.

From Effective Go:

To delete a map entry, use the delete built-in function, whose arguments are the map and the key to be deleted. It's safe to do this even if the key is already absent from the map.

delete(timeZone, "PDT")  // Now on Standard Time

Instead of implementing a "constants interface", in Java 1.5+, you can use static imports to import the constants/static methods from another class/interface:

import static com.kittens.kittenpolisher.KittenConstants.*;

This avoids the ugliness of making your classes implement interfaces that have no functionality.

As for the practice of having a class just to store constants, I think it's sometimes necessary. There are certain constants that just don't have a natural place in a class, so it's better to have them in a "neutral" place.

But instead of using an interface, use a final class with a private constructor. (Making it impossible to instantiate or subclass the class, sending a strong message that it doesn't contain non-static functionality/data.)

Eg:

/** Set of constants needed for Kitten Polisher. */
public final class KittenConstants
{
    private KittenConstants() {}

    public static final String KITTEN_SOUND = "meow";
    public static final double KITTEN_CUTENESS_FACTOR = 1;
}

As mentioned in other answers you can use:

>> tic; x=5*ones(10,1); toc
Elapsed time is 0.000415 seconds.

An even faster method is:

>> tic;  x=5; x=x(ones(10,1)); toc
Elapsed time is 0.000257 seconds.

There is a quick method to set the syntax: Ctrl+Shift+P,then type in the input box

ss + (which type you want set)

eg: ss html +Enter

and ss means "set syntax"

it is really quicker than check in the menu's checkbox.

my two cents worth ~

Cloud refers to an (imaginary/easily scalable) unlimited space and processing power. The term shields the underlying technologies and highlights solely its unlimited storage-space and power.

Grid is a group of physically close-by machines setup. Term usually imply the processing power (ie:MFLOPS/GFLOPS), referred by engineers

Cluster is a set of logically connected machines/device (like a clusters of harddisk, cluster of database). Term highlights how devices are able to connect together and operate as a unit, referred by engineers

I had the same error, what solve my problem was. In my library instead of using compile or implementation i use "api". So in the end my dependencies:

dependencies {

testApi 'junit:junit:4.12'
api 'com.android.support:percent:26.0.0-beta2'

Mine was caused by a corrupt Maven repository.

I deleted everything under C:\Users\<me>\.m2\repository.

Then did an Eclipse Maven Update, and it worked first time.

So it was simply spring-boot.jar got corrupted.

As part of htmlAttributes,e.g.

Html.BeginForm(
    action, controller, FormMethod.Post, new { enctype="multipart/form-data"})

Or you can pass null for action and controller to get the same default target as for BeginForm() without any parameters:

Html.BeginForm(
    null, null, FormMethod.Post, new { enctype="multipart/form-data"})

This answer is going to briefly explain how the native files are handled on the latest launcher.

As of 4/29/2017 the Minecraft launcher for Windows extracts all native files and places them info %APPDATA%\Local\Temp{random folder}. That folder is temporary and is deleted once the javaw.exe process finishes (when Minecraft is closed). The location of that temporary folder must be provided in the launch arguments as the value of

-Djava.library.path=

Also, the latest launcher (2.0.847) does not show you the launch arguments so if you need to check them yourself you can do so under the Task Manager (simply enable the Command Line tab and expand it) or by using the WMIC utility as explained here.

Hope this helps some people who are still interested in doing this in 2017.

MySQLi is part of PHP. There should be a php-mysqli type package available, or you can take the PHP source and recompile that mysqli enabled. You may already have it installed, but it's done as a module and is disabled. Check your php.ini for extension=mysqli.so or similar. it may be commented out, or the .so file is present in your extensions directory but not linked to PHP via that extension= directive.

Try this. It's simplistic, but probably not the best method.

from pygame import mixer  # Load the popular external library

mixer.init()
mixer.music.load('e:/LOCAL/Betrayer/Metalik Klinik1-Anak Sekolah.mp3')
mixer.music.play()

Please note that pygame's support for MP3 is limited. Also, as pointed out by Samy Bencherif, there won't be any silly pygame window popup when you run the above code.

Installation is simple -

pip install pygame

you can use git name-rev --name-only HEAD

You could also do:

 for option in options:
      if option == options[selected_index]:
           #print
      else:
           #print

Although you'd run into issues if there are duplicate options.

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

Check this basic code to setup html server. its work for me.

var http = require('http'),
    fs = require('fs');


fs.readFile('./index.html', function (err, html) {
    if (err) {
        throw err; 
    }       
    http.createServer(function(request, response) {  
        response.writeHeader(200, {"Content-Type": "text/html"});  
        response.write(html);  
        response.end();  
    }).listen(8000);
});

In my experience, printf() hauls in more code than puts() regardless of the format string.

If I don't need the formatting, I don't use printf. However, fwrite to stdout works a lot faster than puts.

static const char my_text[] = "Using fwrite.\n";
fwrite(my_text, 1, sizeof(my_text) - sizeof('\0'), stdout);

Note: per comments, '\0' is an integer constant. The correct expression should be sizeof(char) as indicated by the comments.

For browsers supporting Object.keys() you can simply do:

Object.keys(a).length;

Otherwise (notably in IE < 9), you can loop through the object yourself with a for (x in y) loop:

var count = 0;
var i;

for (i in a) {
    if (a.hasOwnProperty(i)) {
        count++;
    }
}

The hasOwnProperty is there to make sure that you're only counting properties from the object literal, and not properties it "inherits" from its prototype.

Why don't you take a look to this answer

Including javascript files inside javascript files

In short you can load the script file with AJAX or put a script tag on the HTML to include it( before the script that uses the functions of the other script). The link I posted is a great answer and has multiple examples and explanations of both methods.
