You should try something like this, I am doing this for my project, its a fallback system

//function to get the remote data
function url_get_contents ($url) {
    if (function_exists('curl_exec')){ 
        $conn = curl_init($url);
        curl_setopt($conn, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($conn, CURLOPT_FRESH_CONNECT,  true);
        curl_setopt($conn, CURLOPT_RETURNTRANSFER, 1);
        $url_get_contents_data = (curl_exec($conn));
        curl_close($conn);
    }elseif(function_exists('file_get_contents')){
        $url_get_contents_data = file_get_contents($url);
    }elseif(function_exists('fopen') && function_exists('stream_get_contents')){
        $handle = fopen ($url, "r");
        $url_get_contents_data = stream_get_contents($handle);
    }else{
        $url_get_contents_data = false;
    }
return $url_get_contents_data;
} 

then later you can do like this

$data = url_get_contents("http://www.google.com");
if($data){
//Do Something....
}

You JSON is not a valid string as P. Galbraith has told you above.

and here is the solution for it.

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu";
$json = file_get_contents($json_url);
$json=str_replace('},

]',"}

]",$json);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

Use this code it will work for you.

Enable allow_url_fopen From cPanel Or WHM in PHP INI Section

To allow https wrapper:

• the php_openssl extension must exist and be enabled
• allow_url_fopen must be set to on

In the php.ini file you should add this lines if not exists:

extension=php_openssl.dll

allow_url_fopen = On

Yes! By passing a stream context in the third parameter:

Here with a timeout of 1s:

file_get_contents("https://abcedef.com", 0, stream_context_create(["http"=>["timeout"=>1]]));

Source in comment section of https://www.php.net/manual/en/function.file-get-contents.php

HTTP context options:

method
header
user_agent
content
request_fulluri
follow_location
max_redirects
protocol_version
timeout

Other contexts: https://www.php.net/manual/en/context.php

Sending an HTTP POST request using file_get_contents is not that hard, actually : as you guessed, you have to use the $context parameter.

There's an example given in the PHP manual, at this page : HTTP context options (quoting) :

$postdata = http_build_query(
    array(
        'var1' => 'some content',
        'var2' => 'doh'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-Type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/submit.php', false, $context);

Basically, you have to create a stream, with the right options (there is a full list on that page), and use it as the third parameter to file_get_contents -- nothing more ;-)

As a sidenote : generally speaking, to send HTTP POST requests, we tend to use curl, which provides a lot of options an all -- but streams are one of the nice things of PHP that nobody knows about... too bad...

file_get_contents() is a simple screwdriver. Great for simple GET requests where the header, HTTP request method, timeout, cookiejar, redirects, and other important things do not matter.

fopen() with a stream context or cURL with setopt are powerdrills with every bit and option you can think of.

I got a similar problem.

Due to timeout !

Timeout can be indicated like this :

$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => "POST",
        'content' => http_build_query($data2),
        'timeout' => 30,
    ),
);
$context = stream_context_create($options); $retour =
$retour = @file_get_contents("http://xxxxx.xxx/xxxx", false, $context);

You can do that, or you can use the readfile function, which outputs it for you:

header('Content-Type: image/x-png'); //or whatever
readfile('thefile.png');
die();

Edit: Derp, fixed obvious glaring typo.

original answer moved to this topic .

Use file_get_contents in combination with json_decode and echo.

I had a similar problem, what solved it was html_entity_decode.

My code is:

$content = file_get_contents("http://example.com/fr");
$x = new SimpleXMLElement($content);
foreach($x->channel->item as $entry) {
    $subEntry = html_entity_decode($entry->description);
}

In here I am retrieving an xml file (in French), that's why I'm using this $x object variable. And only then I decode it into this variable $subEntry.

I tried mb_convert_encoding but this didn't work for me.

I had the same issue for another secure page when using wget or file_get_contents. A lot of research (including some of the responses on this question) resulted in a simple solution - installing Curl and PHP-Curl - If I've understood correctly, Curl has the Root CA for Comodo which resolved the issue

Install Curl and PHP-Curl addon, then restart Apache

sudo apt-get install curl
sudo apt-get install php-curl
sudo /etc/init.d/apache2 reload

All now working.

Wrap your $adr in urlencode(). I was having this problem and this solved it for me.

JSONP allows you to specify a callback function that is passed your JSON object. This allows you to bypass the same origin policy and load JSON from an external server into the JavaScript on your webpage.

I do realize that the author asks question in relation to a class-based component, however I think it's worth mentioning that as of React 16.8.0 (February 6, 2019) you can take advantage of hooks in function-based components.

Example code:

import { useRef } from 'react'

function Component() {
  const inputRef = useRef()

  return (
    <input ref={inputRef} />
    <div
      onScroll={() => {
        const { offsetTop } = inputRef.current
        ...
      }}
    >
  )
}

The best solution is the attribute selector in CSS (input[type="text"]) as the others suggested.

But if you have to support Internet Explorer 6, you cannot use it (QuirksMode). Well, only if you have to and also are willing to support it.

In this case your only option seems to be to define classes on input elements.

<input type="text" class="input-box" ... />
<input type="submit" class="button" ... />
...

and target them with a class selector:

input.input-box, textarea { background: cyan; }

I preffer the following way, it can be used by any button.

<button class='pushme' data-default-text="PUSH ME" data-new-text="DON'T PUSH ME">PUSH ME</button>

$(".pushme").click(function () {
    var $element = $(this);
    $element.text(function(i, text) {
        return text == $element.data('default-text') ? $element.data('new-text')
                                                     : $element.data('default-text');
    });
});

Or just use interactive configuration:

sudo mysql_secure_installation

From Linux Terminal:

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

From Windows PowerShell:

adb shell 
getprop | grep -e 'model' -e 'version.sdk' -e 'manufacturer' -e 'hardware' -e 'platform' -e 'revision' -e 'serialno' -e 'product.name' -e 'brand'

Sample output for Samsung:

[gsm.version.ril-impl]: [Samsung RIL v3.0]
[net.knoxscep.version]: [2.0.1]

You can do this also:

Let’s say df is your dataframe. Then df.shape gives you the shape of your dataframe i.e (row,col)

Thus, assign the below command to get the required

 row = df.shape[0], col = df.shape[1]

dex file is a file that is executed on the Dalvik VM.

Dalvik VM includes several features for performance optimization, verification, and monitoring, one of which is Dalvik Executable (DEX).

Java source code is compiled by the Java compiler into .class files. Then the dx (dexer) tool, part of the Android SDK processes the .class files into a file format called DEX that contains Dalvik byte code. The dx tool eliminates all the redundant information that is present in the classes. In DEX all the classes of the application are packed into one file. The following table provides comparison between code sizes for JVM jar files and the files processed by the dex tool.

The table compares code sizes for system libraries, web browser applications, and a general purpose application (alarm clock app). In all cases dex tool reduced size of the code by more than 50%.

In standard Java environments each class in Java code results in one .class file. That means, if the Java source code file has one public class and two anonymous classes, let’s say for event handling, then the java compiler will create total three .class files.

The compilation step is same on the Android platform, thus resulting in multiple .class files. But after .class files are generated, the “dx” tool is used to convert all .class files into a single .dex, or Dalvik Executable, file. It is the .dex file that is executed on the Dalvik VM. The .dex file has been optimized for memory usage and the design is primarily driven by sharing of data.

You want to treat dot (.) like comma (,). So, replace

if (double.TryParse(values[i, j], out tmp))

with

if (double.TryParse(values[i, j].Replace('.', ','), out tmp))

In your JSON format, it do not have starting JSON object

Like :

{
    "info" :       <!-- this is starting JSON object -->
        {
        "caller":"getPoiById",
        "results":
        {
            "indexForPhone":0,
            "indexForEmail":"NULL",
            .
            .
         }
    }
}

Above Json starts with info as JSON object. So while executing :

JSONObject json = new JSONObject(result);    // create JSON obj from string
JSONObject json2 = json.getJSONObject("info");    // this will return correct

Now, we can access result field :

JSONObject jsonResult = json2.getJSONObject("results");
test = json2.getString("name"); // returns "Marina Rasche Werft GmbH & Co. KG"

I think this was missing and so the problem was solved while we use JSONTokener like answer of yours.

Your answer is very fine. Just i think i add this information so i answered

Thank you

The change event not firing on deselection is the desired behaviour. You should run a selector over the entire radio group rather than just the single radio button. And your radio group should have the same name (with different values)

Consider the following code:

$('input[name="job[video_need]"]').on('change', function () {
    var value;
    if ($(this).val() == 'none') {
        value = 'hide';
    } else {
        value = 'show';
    }
    $('#video-script-collapse').collapse(value);
});

I have same use case as yours i.e. to show an input box when a particular radio button is selected. If the event was fired on de-selection as well, I would get 2 events each time.

An alternative General Plan, which I'm only adding as an independent Answer because the blasted "comment on an answer" won't take newlines without posting the entire edit, even though it isn't finished yet.

UPDATE table A
JOIN table B ON {join fields}
JOIN table C ON {join fields}
JOIN {as many tables as you need}
SET A.column = {expression}

Example:

UPDATE person P
JOIN address A ON P.home_address_id = A.id
JOIN city C ON A.city_id = C.id
SET P.home_zip = C.zipcode;

The fact that you're using a view model has no bearing. The standard way of using PagedList is to store "one page of items" as a ViewBag variable. All you have to determine is what collection constitutes what you'll be paging over. You can't logically page multiple collections at the same time, so assuming you chose Instructors:

ViewBag.OnePageOfItems = myViewModelInstance.Instructors.ToPagedList(pageNumber, 10);

Then, the rest of the standard code works as it always has.

It's the remainder operator and is used to get the remainder after integer division. Lots of languages have it. For example:

10 % 3 // = 1 ; because 3 * 3 gets you 9, and 10 - 9 is 1.

Apparently it is not the same as the modulo operator entirely.

file_get_contents('php://input') will not always work.

I have a request with in the headers "content-length=735" and "php://input" is empty string. So depends on how good/valid the HTTP request is.

It is language dependent - IIRC C# optimises this, so there isn't any difference, but JavaScript (for example) will do the whole memory allocation shebang each time.

Maybe something like this:

sed 's/ab/~~/g; s/bc/ab/g; s/~~/bc/g'

Replace ~ with a character that you know won't be in the string.

Recently I found a quite interesting solution to the problem.

You could use appearance: none; to turn off the checkbox's default style and then write your own over it like described here (Example 4).

Example fiddle

input[type=checkbox] {_x000D_
  width: 23px;_x000D_
  height: 23px;_x000D_
  -webkit-appearance: none;_x000D_
  -moz-appearance: none;_x000D_
  appearance: none;_x000D_
  margin-right: 10px;_x000D_
  background-color: #878787;_x000D_
  outline: 0;_x000D_
  border: 0;_x000D_
  display: inline-block;_x000D_
  -webkit-box-shadow: none !important;_x000D_
  -moz-box-shadow: none !important;_x000D_
  box-shadow: none !important;_x000D_
}_x000D_
_x000D_
input[type=checkbox]:focus {_x000D_
  outline: none;_x000D_
  border: none !important;_x000D_
  -webkit-box-shadow: none !important;_x000D_
  -moz-box-shadow: none !important;_x000D_
  box-shadow: none !important;_x000D_
}_x000D_
_x000D_
input[type=checkbox]:checked {_x000D_
  background-color: green;_x000D_
  text-align: center;_x000D_
  line-height: 15px;_x000D_
}

<input type="checkbox">

Unfortunately browser support is quite bad for the appearance option. From my personal testing I only got Opera and Chrome working correctly. But this would be the way to go to keep it simple when better support comes or you only want to use Chrome/Opera.

"Can I use?" link

A simpler way to do this would be:

Sub populateB()

For Each Cel in Range("A1:A100")
    If Cel.value <> "" Then Cel.Offset(0, 1).value = "Your Text"
Next

End Sub

Move doSomething definition outside of its class declaration and after B and also make add accessible to A by public-ing it or friend-ing it.

class B;

class A
{
    void doSomething(B * b);
};

class B
{
public:
    void add() {}
};

void A::doSomething(B * b)
{
    b->add();
}

If you're just trying to find out where npm is installing your global module (the title of this thread), look at the output when running npm install -g sample_module

$ npm install -g sample_module C:\Users\user\AppData\Roaming\npm\sample_module -> C:\Users\user\AppData\Roaming\npm\node_modules\sample_module\bin\sample_module.js + [email protected] updated 1 package in 2.821s

You could use PHP's json_decode function:

$url = "http://urlToYourJsonFile.com";
$json = file_get_contents($url);
$json_data = json_decode($json, true);
echo "My token: ". $json_data["access_token"];

Swift 2.0

Well I worked out. Have a look. Made a ViewController in StoryBoard. Associated with PopOverViewController class.

import UIKit

class PopOverViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()    
        self.preferredContentSize = CGSizeMake(200, 200)    
        self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Done, target: self, action: "dismiss:")    
    }    
    func dismiss(sender: AnyObject) {
        self.dismissViewControllerAnimated(true, completion: nil)
    }
}      

See ViewController:

//  ViewController.swift

import UIKit

class ViewController: UIViewController, UIPopoverPresentationControllerDelegate
{
    func showPopover(base: UIView)
    {
        if let viewController = self.storyboard?.instantiateViewControllerWithIdentifier("popover") as? PopOverViewController {    

            let navController = UINavigationController(rootViewController: viewController)
            navController.modalPresentationStyle = .Popover

            if let pctrl = navController.popoverPresentationController {
                pctrl.delegate = self

                pctrl.sourceView = base
                pctrl.sourceRect = base.bounds

                self.presentViewController(navController, animated: true, completion: nil)
            }
        }
    }    
    override func viewDidLoad(){
        super.viewDidLoad()
    }    
    @IBAction func onShow(sender: UIButton)
    {
        self.showPopover(sender)
    }    
    func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
        return .None
    }
}  

Note: The func showPopover(base: UIView) method should be placed before ViewDidLoad. Hope it helps !

I was getting the same error because of jquery CDN (<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>) was added two times in the HTML head.

Ian put this in the comment, but I think it's a good answer:

if (exists("aVariable"))
{
  do whatever
}

note that the variable name is quoted.

Is there an object that acts like a Map for storing and accessing key/value pairs, but can return an ordered list of keys and an ordered list of values, such that the key and value lists are in the same order?

You're looking for java.util.LinkedHashMap. You'll get a list of Map.Entry<K,V> pairs, which always get iterated in the same order. That order is the same as the order by which you put the items in. Alternatively, use the java.util.SortedMap, where the keys must either have a natural ordering or have it specified by a Comparator.

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

Oracle specific, and doesn't rely on pre-existing large tables or complicated system views over data dictionary objects.

SELECT c1 from dual

For z-index to work, you also need to give it a position:

header {
    width: 100%;
    height: 100px;
    background: url(../img/top.png) repeat-x;
    z-index: 110;
    position: relative;
}

If "partly cherry picking" means "within files, choosing some changes but discarding others", it can be done by bringing in git stash:

1. Do the full cherry pick.
2. git reset HEAD^ to convert the entire cherry-picked commit into unstaged working changes.
3. Now git stash save --patch: interactively select unwanted material to stash.
4. Git rolls back the stashed changes from your working copy.
5. git commit
6. Throw away the stash of unwanted changes: git stash drop.

Tip: if you give the stash of unwanted changes a name: git stash save --patch junk then if you forget to do (6) now, later you will recognize the stash for what it is.

It is simple. The first thing that you have to understand the design of the Python interpreter. It doesn't allocate memory for all the variables basically if any two or more variable has the same value it just map to that value.

let's go to the code example,

In [6]: a = 10

In [7]: id(a)
Out[7]: 10914656

In [8]: b = 10

In [9]: id(b)
Out[9]: 10914656

In [10]: c = 11

In [11]: id(c)
Out[11]: 10914688

In [12]: d = 21

In [13]: id(d)
Out[13]: 10915008

In [14]: e = 11

In [15]: id(e)
Out[15]: 10914688

In [16]: e = 21

In [17]: id(e)
Out[17]: 10915008

In [18]: e is d
Out[18]: True
In [19]: e = 30

In [20]: id(e)
Out[20]: 10915296

From the above output, variables a and b shares the same memory, c and d has different memory when I create a new variable e and store a value (11) which is already present in the variable c so it mapped to that memory location and doesn't create a new memory when I change the value present in the variable e to 21 which is already present in the variable d so now variables d and e share the same memory location. At last, I change the value in the variable e to 30 which is not stored in any other variable so it creates a new memory for e.

so any variable which is having same value shares the memory.

Not for list and dictionary objects

let's come to your question.

when multiple keys have same value then all shares same memory so the thing that you expect is already there in python.

you can simply use it like this

In [49]: dictionary = {
    ...:     'k1':1,
    ...:     'k2':1,
    ...:     'k3':2,
    ...:     'k4':2}
    ...:     
    ...:     

In [50]: id(dictionary['k1'])
Out[50]: 10914368

In [51]: id(dictionary['k2'])
Out[51]: 10914368

In [52]: id(dictionary['k3'])
Out[52]: 10914400

In [53]: id(dictionary['k4'])
Out[53]: 10914400

From the above output, the key k1 and k2 mapped to the same address which means value one stored only once in the memory which is multiple key single value dictionary this is the thing you want. :P

#define NAME(x) printf("Hello " #x);
main(){
    NAME(Ian)
}
//will print: Hello Ian

Could you do the following:

obj = {
    "1":"aa",
    "2":"bb"
};


var newNum = "3";
var newVal = "cc";


obj[newNum] = newVal;



alert(obj["3"]); // this would alert 'cc'

Something like this should work: From Frans Bouma's Blog

SELECT * FROM
(
    SELECT a.*, rownum r__
    FROM
    (
        SELECT * FROM ORDERS WHERE CustomerID LIKE 'A%'
        ORDER BY OrderDate DESC, ShippingDate DESC
    ) a
    WHERE rownum < ((pageNumber * pageSize) + 1 )
)
WHERE r__ >= (((pageNumber-1) * pageSize) + 1)

If you are getting this error, it could be because you don't have a route defined for your get.

For example:

const express = require('express');

const app = express();

app.get('/people', function (req, res) {
    res.send('hello');
})

app.listen(3000);


http://http://localhost:3000/people --> this works
http://http://localhost:3000 --> this will output Cannot GET / message.

I used vw (viewport width) and vh (viewport height). viewport is your entire screen. 100vw is your screens total width and 100vh is total height.

.class_name{
    width: 50vw;
    height: 50vh;
    border: 1px solid red;
    position: fixed;
    left: 25vw;top: 25vh;

Or, you could try changing the parameter type to string, then convert the string to an integer in the method. I am new to MVC, but I believe you need nullable objects in your parameter list, how else will the controller indicate that no such parameter was provided? So...

public ActionResult ViewNextItem(string id)...

There are no provisions in C++ to test for the validity of a pointer as a general case. One can obviously assume that NULL (0x00000000) is bad, and various compilers and libraries like to use "special values" here and there to make debugging easier (For example, if I ever see a pointer show up as 0xCECECECE in visual studio I know I did something wrong) but the truth is that since a pointer is just an index into memory it's near impossible to tell just by looking at the pointer if it's the "right" index.

There are various tricks that you can do with dynamic_cast and RTTI such to ensure that the object pointed to is of the type that you want, but they all require that you are pointing to something valid in the first place.

If you want to ensure that you program can detect "invalid" pointers then my advice is this: Set every pointer you declare either to NULL or a valid address immediately upon creation and set it to NULL immediately after freeing the memory that it points to. If you are diligent about this practice, then checking for NULL is all you ever need.

Use the low-level $.ajax() call:

$.ajax({
  url: "/yourservlet",
  data: { },
  complete: function(xmlHttp) {
    // xmlHttp is a XMLHttpRquest object
    alert(xmlHttp.status);
  }
});

Try this for a redirect:

if (xmlHttp.code != 200) {
  top.location.href = '/some/other/page';
}

You can format your output in Java as described in below code snippet.

public class TestFormat {

    public static void main(String[] args) {
      long n = 461012;
      System.out.format("%d%n", n);      //  -->  "461012"
      System.out.format("%08d%n", n);    //  -->  "00461012"
      System.out.format("%+8d%n", n);    //  -->  " +461012"
      System.out.format("%,8d%n", n);    // -->  " 461,012"
      System.out.format("%+,8d%n%n", n); //  -->  "+461,012"
   }
}

dataString suggests the data is formatted in a string (and maybe delimted by a character).

$data = explode(",", $_POST['data']);
foreach($data as $d){
     echo $d;
}

if dataString is not a string but infact an array (what your question indicates) use JSON.

Let's look at this with the help of an example. Suppose we have a direct mapped cache and the write back policy is used. So we have a valid bit, a dirty bit, a tag and a data field in a cache line. Suppose we have an operation : write A ( where A is mapped to the first line of the cache).

What happens is that the data(A) from the processor gets written to the first line of the cache. The valid bit and tag bits are set. The dirty bit is set to 1.

Dirty bit simply indicates was the cache line ever written since it was last brought into the cache!

Now suppose another operation is performed : read E(where E is also mapped to the first cache line)

Since we have direct mapped cache, the first line can simply be replaced by the E block which will be brought from memory. But since the block last written into the line (block A) is not yet written into the memory(indicated by the dirty bit), so the cache controller will first issue a write back to the memory to transfer the block A to memory, then it will replace the line with block E by issuing a read operation to the memory. dirty bit is now set to 0.

So write back policy doesnot guarantee that the block will be the same in memory and its associated cache line. However whenever the line is about to be replaced, a write back is performed at first.

A write through policy is just the opposite. According to this, the memory will always have a up-to-date data. That is, if the cache block is written, the memory will also be written accordingly. (no use of dirty bits)

Here's a response to your latest question about the difference between x86_64 and arm64:

• x86_64 architecture is required for running the 64bit simulator.

• arm64 architecture is required for running the 64bit device (iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini with Retina display).

You are getting this is because you are using a Anaconda distribution of Jupyter notebook. So just do conda install pandas restart your jupyter notebook and rerun your cell. It should work. If you are trying this on a Virtual Env try this

1. conda create -n name_of_my_env python This will create a minimal environment with only Python installed in it. To put your self inside this environment run:

2 source activate name_of_my_env On Windows the command is: activate name_of_my_env The final step required is to install pandas. This can be done with the following command:

conda install pandas To install a specific pandas version:

conda install pandas=0.20.3

To install other packages, IPython for example:

conda install ipython To install the full Anaconda distribution:

conda install anaconda

If you need packages that are available to pip but not conda, then install pip, and then use pip to install those packages:

conda install pip pip install django Installing from PyPI pandas can be installed via pip from PyPI.

pip install pandas Installing with ActivePython

Hope this helps.

Unfortunately, strptime() can only handle the timezone configured by your OS, and then only as a time offset, really. From the documentation:

Support for the %Z directive is based on the values contained in tzname and whether daylight is true. Because of this, it is platform-specific except for recognizing UTC and GMT which are always known (and are considered to be non-daylight savings timezones).

strftime() doesn't officially support %z.

You are stuck with python-dateutil to support timezone parsing, I am afraid.

Any of LinearLayout.LayoutParams and TableLayout.LayoutParams worked for me, for buttons the right one is TableRow.LayoutParams. That is:

            TableRow.LayoutParams buttonParams = new TableRow.LayoutParams(
                    TableRow.LayoutParams.MATCH_PARENT,
                    TableRow.LayoutParams.WRAP_CONTENT, 1f);

About using MATCH_PARENT or WRAP_CONTENT be the same.

The name property is marked as protected. This was added in TypeScript 1.3 and is now firmly established.

The makeSound method is marked as abstract, as is the class. You cannot directly instantiate an Animal now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.

abstract class Animal {
    constructor(protected name: string) { }

    abstract makeSound(input : string) : string;

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name: string) { super(name); }

    makeSound(input : string) : string {
        return "sssss"+input;
    }

    move() {
        alert("Slithering...");
        super.move(5);
    }
}

The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:

class Animal {
    constructor(public name) { }
    makeSound(input : string) : string {
        throw new Error('This method is abstract');
    }
    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name) { super(name); }
    makeSound(input : string) : string {
        return "sssss"+input;
    }
    move() {
        alert("Slithering...");
        super.move(5);
    }
}

Unified Solution:

In order to work on all modern browsers, you will need two steps:

1. Add javascript:void(0); as src attribute for the iframe element. Otherwise the content will be overriden by the empty src on Firefox.

   <iframe src="javascript:void(0);"></iframe>
   

2. Programatically change the content of the inner html element.

   $(iframeSelector).contents().find('html').html(htmlContent);

Use

[A-Z]?

to make the letter optional. {1} is redundant. (Of course you could also write [A-Z]{0,1} which would mean the same, but that's what the ? is there for.)

You could improve your regex to

^([0-9]{5})+\s+([A-Z]?)\s+([A-Z])([0-9]{3})([0-9]{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])[0-9]{3}([0-9]{4})([0-9]{2})([0-9]{2})

And, since in most regex dialects, \d is the same as [0-9]:

^(\d{5})+\s+([A-Z]?)\s+([A-Z])(\d{3})(\d{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])\d{3}(\d{4})(\d{2})(\d{2})

But: do you really need 11 separate capturing groups? And if so, why don't you capture the fourth-to-last group of digits?

function printDiv() {
    var divToPrint = document.getElementById('printArea');
    newWin= window.open();
    newWin.document.write(divToPrint.innerHTML);
    newWin.location.reload();
    newWin.focus();
    newWin.print();
    newWin.close();
}

This is what we called Composite Formatting of the .NET Framework to convert the value of an object to its text representation and embed that representation in a string. The resulting string is written to the output stream.

The overloaded Console.WriteLine Method (String, Object)Writes the text representation of the specified object, followed by the current line terminator, to the standard output stream using the specified format information.

Put the CSS files in public/stylesheets and then use:

<%= stylesheet_link_tag "filename" %>

to link to the stylesheet in your layouts or erb files in your views.

Similarly you put images in public/images and javascript files in public/javascripts.

In dead simple way it makes this meaning.

Functions :

These subprograms return a single value; mainly used to compute and return a value.

Procedure :

These subprograms do not return a value directly; mainly used to perform an action.

Example Program:

CREATE OR REPLACE PROCEDURE greetings

BEGIN 

dbms_output.put_line('Hello World!');

END ;
/

Executing a Standalone Procedure :

A standalone procedure can be called in two ways:

• Using the EXECUTE keyword • Calling the name of procedure from a PL/SQL block

The procedure can also be called from another PL/SQL block:

BEGIN 
greetings;
END;
/

Function:

CREATE OR REPLACE FUNCTION totalEmployees 
RETURN number IS
total number(3) := 0;
BEGIN 
SELECT count(*) into total 
FROM employees;
RETURN total; 
END;
/

Following program calls the function totalCustomers from an another block

DECLARE 
c number(3);
BEGIN 
c := totalEmployees();
dbms_output.put_line('Total no. of Employees: ' || c);
END;
/

This isn't a very beautiful answer, but it's what I use to create zero-length vectors:

0[-1]     # numeric
""[-1]    # character
TRUE[-1]  # logical
0L[-1]    # integer

A literal is a vector of length 1, and [-1] removes the first element (the only element in this case) from the vector, leaving a vector with zero elements.

As a bonus, if you want a single NA of the respective type:

0[NA]     # numeric
""[NA]    # character
TRUE[NA]  # logical
0L[NA]    # integer

To help everyone avoid confusion, I will reformulate the question in two parts.

First : "how can make an authenticated HTTP request with a browser, using BASIC auth?".

In the browser you can do a http basic auth first by waiting the prompt to come, or by editing the URL if you follow this format: http://myusername:[email protected]

NB: the curl command mentionned in the question is perfectly fine, if you have a command-line and curl installed. ;)

References:

• https://en.wikipedia.org/wiki/Basic_access_authentication#URL_encoding
• https://en.wikipedia.org/wiki/Uniform_Resource_Locator#Syntax
• https://tools.ietf.org/html/rfc3986#page-18

Also according to the CURL manual page https://curl.haxx.se/docs/manual.html

HTTP

  Curl also supports user and password in HTTP URLs, thus you can pick a file
  like:

      curl http://name:[email protected]/full/path/to/file

  or specify user and password separately like in

      curl -u name:passwd http://machine.domain/full/path/to/file

  HTTP offers many different methods of authentication and curl supports
  several: Basic, Digest, NTLM and Negotiate (SPNEGO). Without telling which
  method to use, curl defaults to Basic. You can also ask curl to pick the
  most secure ones out of the ones that the server accepts for the given URL,
  by using --anyauth.

  NOTE! According to the URL specification, HTTP URLs can not contain a user
  and password, so that style will not work when using curl via a proxy, even
  though curl allows it at other times. When using a proxy, you _must_ use
  the -u style for user and password.

The second and real question is "However, on somesite.com, I'm not getting an authorization prompt at all, just a page that says I'm not authorized. Did somesite not implement the Basic Auth workflow correctly, or is there something else I need to do?"

The curl documentation says the -u option supports many method of authentication, Basic being the default.

Below is for Python-

df.select("col_name").rdd.flatMap(lambda x: x).collect()

Before datalist (see note below), you would supply an additional input element for people to type in their own option.

<select name="example">
  <option value="A">A</option>
  <option value="B">B</option>
  <option value="-">Other</option>
</select>

<input type="text" name="other">

This mechanism works in all browsers and requires no JavaScript.

You could use a little JavaScript to be clever about only showing the input if the "Other" option was selected.

datalist Element

The datalist element is intended to provide a better mechanism for this concept. In some browsers, e.g. iOS Safari < 12.2, this was not supported or the implementation had issues. Check the Can I Use page to see current datalist support.

<input type="text" name="example" list="exampleList">
<datalist id="exampleList">
  <option value="A">  
  <option value="B">
</datalist>

Although that did work, it took out the entire background colour as well. I was looking for a way to do just the border and just replace that XML layout code with this one and I was good to go!

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="4dp" android:color="#FF00FF00" />
    <padding android:left="7dp" android:top="7dp"
            android:right="7dp" android:bottom="7dp" />
    <corners android:radius="4dp" />
</shape> 

Suppose you have this file:

$ cat /tmp/test.txt
Line 1
    Line 2 has leading space
Line 3 followed by blank line

Line 5 (follows a blank line) and has trailing space    
Line 6 has no ending CR

There are four elements that will alter the meaning of the file output read by many Bash solutions:

1. The blank line 4;
2. Leading or trailing spaces on two lines;
3. Maintaining the meaning of individual lines (i.e., each line is a record);
4. The line 6 not terminated with a CR.

If you want the text file line by line including blank lines and terminating lines without CR, you must use a while loop and you must have an alternate test for the final line.

Here are the methods that may change the file (in comparison to what cat returns):

1) Lose the last line and leading and trailing spaces:

$ while read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'

(If you do while IFS= read -r p; do printf "%s\n" "'$p'"; done </tmp/test.txt instead, you preserve the leading and trailing spaces but still lose the last line if it is not terminated with CR)

2) Using process substitution with cat will reads the entire file in one gulp and loses the meaning of individual lines:

$ for p in "$(cat /tmp/test.txt)"; do printf "%s\n" "'$p'"; done
'Line 1
    Line 2 has leading space
Line 3 followed by blank line

Line 5 (follows a blank line) and has trailing space    
Line 6 has no ending CR'

(If you remove the " from $(cat /tmp/test.txt) you read the file word by word rather than one gulp. Also probably not what is intended...)

The most robust and simplest way to read a file line-by-line and preserve all spacing is:

$ while IFS= read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
'    Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space    '
'Line 6 has no ending CR'

If you want to strip leading and trading spaces, remove the IFS= part:

$ while read -r line || [[ -n $line ]]; do printf "'%s'\n" "$line"; done </tmp/test.txt
'Line 1'
'Line 2 has leading space'
'Line 3 followed by blank line'
''
'Line 5 (follows a blank line) and has trailing space'
'Line 6 has no ending CR'

(A text file without a terminating \n, while fairly common, is considered broken under POSIX. If you can count on the trailing \n you do not need || [[ -n $line ]] in the while loop.)

It may means that you forgot include a header file that define this struct/union. For example:

foo.h file:

typedef union
{
    struct
    {
        uint8_t FIFO_BYTES_AVAILABLE    : 4;
        uint8_t STATE                   : 3;
        uint8_t CHIP_RDY                : 1;
    };
    uint8_t status;
} RF_CHIP_STATUS_t;

RF_CHIP_STATUS_t getStatus();

main.c file:

.
.
.
if (getStatus().CHIP_RDY) /* This will generate the error, you must add the  #include "foo.h" */
.
.
.

The problem is that jQuery doesn't trigger the native click event for <a> elements so that navigation doesn't happen (the normal behavior of an <a>), so you need to do that manually. For almost all other scenarios, the native DOM event is triggered (at least attempted to - it's in a try/catch).

To trigger it manually, try:

var a = $("<a>")
    .attr("href", "http://i.stack.imgur.com/L8rHf.png")
    .attr("download", "img.png")
    .appendTo("body");

a[0].click();

a.remove();

DEMO: http://jsfiddle.net/HTggQ/

Relevant line in current jQuery source: https://github.com/jquery/jquery/blob/1.11.1/src/event.js#L332

if ( (!special._default || special._default.apply( eventPath.pop(), data ) === false) &&
        jQuery.acceptData( elem ) ) {

Those methods to tell if a function is implemented also fail if variable is not defined so we are using something more powerful that supports receiving an string:

function isFunctionDefined(functionName) {
    if(eval("typeof(" + functionName + ") == typeof(Function)")) {
        return true;
    }
}

if (isFunctionDefined('myFunction')) {
    myFunction(foo);
}

I just found the solution, kind of answering to my own question in case anyone else stumbles upon it.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); }

I'm building a booking system and found this page. I'm interested in range intersection only, so I built this structure; it is enough to play with DateTime ranges.

There are several ways to do it. The subplots method creates the figure along with the subplots that are then stored in the ax array. For example:

import matplotlib.pyplot as plt

x = range(10)
y = range(10)

fig, ax = plt.subplots(nrows=2, ncols=2)

for row in ax:
    for col in row:
        col.plot(x, y)

plt.show()

However, something like this will also work, it's not so "clean" though since you are creating a figure with subplots and then add on top of them:

fig = plt.figure()

plt.subplot(2, 2, 1)
plt.plot(x, y)

plt.subplot(2, 2, 2)
plt.plot(x, y)

plt.subplot(2, 2, 3)
plt.plot(x, y)

plt.subplot(2, 2, 4)
plt.plot(x, y)

plt.show()

Some points.

Use $.data Instead of $.fn.data

// regular
$(elem).data(key,value);
// 10x faster
$.data(elem,key,value);

Then, You can get the previous value through the event object, without complicating your life:

    $('#myInputElement').change(function(event){
        var defaultValue = event.target.defaultValue;
        var newValue = event.target.value;
    });

Be warned that defaultValue is NOT the last set value. It's the value the field was initialized with. But you can use $.data to keep track of the "oldValue"

I recomend you always declare the "event" object in your event handler functions and inspect them with firebug (console.log(event)) or something. You will find a lot of useful things there that will save you from creating/accessing jquery objects (which are great, but if you can be faster...)

Three steps needed:

1. Explicitly mark SSL2.0, TLS1.0, TLS1.1 as forbidden on your server machine, by adding Enabled=0 and DisabledByDefault=1 to your registry (the full path is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols). See screen for details

2. Explicitly enable TLS1.2 by following the steps from 1. Just use Enabled=1 and DisabledByDefault=0 respectively.

NOTE: verify server version: Windows Server 2003 does not support the TLS 1.2 protocol

3. Enable TLS1.2 only on app level, like @John Wu suggested above.

   System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Hope this guide helps.

UPDATE As @Subbu mentioned: Official guide

//How about byte-ing it?

Number.prototype.isInt= function(){
 return this== this>> 0;
}

I always feel kind of bad for bit operators in javascript-

they hardly get any exercise.

You need to do

Update table_xpto
set column_xpto = x.xpto_New
    ,column2 = x.column2New
from table_xpto xpto
   inner join table_xptoNew xptoNew ON xpto.bla = xptoNew.Bla
where <clause where>

If you need a better answer, you can give us more information :)

Given the proliferation of different ways to read an Excel file in R and the plethora of answers here, I thought I'd try to shed some light on which of the options mentioned here perform the best (in a few simple situations).

I myself have been using xlsx since I started using R, for inertia if nothing else, and I recently noticed there doesn't seem to be any objective information about which package works better.

Any benchmarking exercise is fraught with difficulties as some packages are sure to handle certain situations better than others, and a waterfall of other caveats.

That said, I'm using a (reproducible) data set that I think is in a pretty common format (8 string fields, 3 numeric, 1 integer, 3 dates):

set.seed(51423)
data.frame(
  str1 = sample(sprintf("%010d", 1:NN)), #ID field 1
  str2 = sample(sprintf("%09d", 1:NN)),  #ID field 2
  #varying length string field--think names/addresses, etc.
  str3 = 
    replicate(NN, paste0(sample(LETTERS, sample(10:30, 1L), TRUE),
                         collapse = "")),
  #factor-like string field with 50 "levels"
  str4 = sprintf("%05d", sample(sample(1e5, 50L), NN, TRUE)),
  #factor-like string field with 17 levels, varying length
  str5 = 
    sample(replicate(17L, paste0(sample(LETTERS, sample(15:25, 1L), TRUE),
                                 collapse = "")), NN, TRUE),
  #lognormally distributed numeric
  num1 = round(exp(rnorm(NN, mean = 6.5, sd = 1.5)), 2L),
  #3 binary strings
  str6 = sample(c("Y","N"), NN, TRUE),
  str7 = sample(c("M","F"), NN, TRUE),
  str8 = sample(c("B","W"), NN, TRUE),
  #right-skewed integer
  int1 = ceiling(rexp(NN)),
  #dates by month
  dat1 = 
    sample(seq(from = as.Date("2005-12-31"), 
               to = as.Date("2015-12-31"), by = "month"),
           NN, TRUE),
  dat2 = 
    sample(seq(from = as.Date("2005-12-31"), 
               to = as.Date("2015-12-31"), by = "month"),
           NN, TRUE),
  num2 = round(exp(rnorm(NN, mean = 6, sd = 1.5)), 2L),
  #date by day
  dat3 = 
    sample(seq(from = as.Date("2015-06-01"), 
               to = as.Date("2015-07-15"), by = "day"),
           NN, TRUE),
  #lognormal numeric that can be positive or negative
  num3 = 
    (-1) ^ sample(2, NN, TRUE) * round(exp(rnorm(NN, mean = 6, sd = 1.5)), 2L)
)

I then wrote this to csv and opened in LibreOffice and saved it as an .xlsx file, then benchmarked 4 of the packages mentioned in this thread: xlsx, openxlsx, readxl, and gdata, using the default options (I also tried a version of whether or not I specify column types, but this didn't change the rankings).

I'm excluding RODBC because I'm on Linux; XLConnect because it seems its primary purpose is not reading in single Excel sheets but importing entire Excel workbooks, so to put its horse in the race on only its reading capabilities seems unfair; and xlsReadWrite because it is no longer compatible with my version of R (seems to have been phased out).

I then ran benchmarks with NN=1000L and NN=25000L (resetting the seed before each declaration of the data.frame above) to allow for differences with respect to Excel file size. gc is primarily for xlsx, which I've found at times can create memory clogs. Without further ado, here are the results I found:

1,000-Row Excel File

benchmark1k <-
  microbenchmark(times = 100L,
                 xlsx = {xlsx::read.xlsx2(fl, sheetIndex=1); invisible(gc())},
                 openxlsx = {openxlsx::read.xlsx(fl); invisible(gc())},
                 readxl = {readxl::read_excel(fl); invisible(gc())},
                 gdata = {gdata::read.xls(fl); invisible(gc())})

# Unit: milliseconds
#      expr       min        lq      mean    median        uq       max neval
#      xlsx  194.1958  199.2662  214.1512  201.9063  212.7563  354.0327   100
#  openxlsx  142.2074  142.9028  151.9127  143.7239  148.0940  255.0124   100
#    readxl  122.0238  122.8448  132.4021  123.6964  130.2881  214.5138   100
#     gdata 2004.4745 2042.0732 2087.8724 2062.5259 2116.7795 2425.6345   100

So readxl is the winner, with openxlsx competitive and gdata a clear loser. Taking each measure relative to the column minimum:

#       expr   min    lq  mean median    uq   max
# 1     xlsx  1.59  1.62  1.62   1.63  1.63  1.65
# 2 openxlsx  1.17  1.16  1.15   1.16  1.14  1.19
# 3   readxl  1.00  1.00  1.00   1.00  1.00  1.00
# 4    gdata 16.43 16.62 15.77  16.67 16.25 11.31

We see my own favorite, xlsx is 60% slower than readxl.

25,000-Row Excel File

Due to the amount of time it takes, I only did 20 repetitions on the larger file, otherwise the commands were identical. Here's the raw data:

# Unit: milliseconds
#      expr        min         lq       mean     median         uq        max neval
#      xlsx  4451.9553  4539.4599  4738.6366  4762.1768  4941.2331  5091.0057    20
#  openxlsx   962.1579   981.0613   988.5006   986.1091   992.6017  1040.4158    20
#    readxl   341.0006   344.8904   347.0779   346.4518   348.9273   360.1808    20
#     gdata 43860.4013 44375.6340 44848.7797 44991.2208 45251.4441 45652.0826    20

Here's the relative data:

#       expr    min     lq   mean median     uq    max
# 1     xlsx  13.06  13.16  13.65  13.75  14.16  14.13
# 2 openxlsx   2.82   2.84   2.85   2.85   2.84   2.89
# 3   readxl   1.00   1.00   1.00   1.00   1.00   1.00
# 4    gdata 128.62 128.67 129.22 129.86 129.69 126.75

So readxl is the clear winner when it comes to speed. gdata better have something else going for it, as it's painfully slow in reading Excel files, and this problem is only exacerbated for larger tables.

Two draws of openxlsx are 1) its extensive other methods (readxl is designed to do only one thing, which is probably part of why it's so fast), especially its write.xlsx function, and 2) (more of a drawback for readxl) the col_types argument in readxl only (as of this writing) accepts some nonstandard R: "text" instead of "character" and "date" instead of "Date".

I'm using next approach:

Product

ProductID OrderID,...

ProductInfo

ProductID Title Name LanguageID

Language

LanguageID Name Culture,....

I think it is the version error.

try installing this in following order:

1. sudo apt-get install python3-mysqldb

2. pip3 install mysqlclient

3. python3 manage.py makemigrations

4. python3 manage.py migrate

- (BOOL)deviceiPhoneOriPod
  {
    NSString *deviceType = [UIDevice currentDevice].model;
    if([deviceType rangeOfString:@"iPhone"].location!=NSNotFound)
      return YES;
    else
      return NO;
  }

From lambda answer, I have made something closer to the requirements.

boolean imageCreated = false;

Bitmap bmp = null;
Marker currentLocationMarker;
private void doSomeCustomizationForMarker(LatLng currentLocation) {
    if (!imageCreated) {
        imageCreated = true;
        Bitmap.Config conf = Bitmap.Config.ARGB_8888;
        bmp = Bitmap.createBitmap(400, 400, conf);
        Canvas canvas1 = new Canvas(bmp);

        Paint color = new Paint();
        color.setTextSize(30);
        color.setColor(Color.WHITE);

        BitmapFactory.Options opt = new BitmapFactory.Options();
        opt.inMutable = true;

        Bitmap imageBitmap=BitmapFactory.decodeResource(getResources(),
                R.drawable.messi,opt);
        Bitmap resized = Bitmap.createScaledBitmap(imageBitmap, 320, 320, true);
        canvas1.drawBitmap(resized, 40, 40, color);

        canvas1.drawText("Le Messi", 30, 40, color);

        currentLocationMarker = mMap.addMarker(new MarkerOptions().position(currentLocation)
                .icon(BitmapDescriptorFactory.fromBitmap(bmp))
                // Specifies the anchor to be at a particular point in the marker image.
                .anchor(0.5f, 1));
    } else {
        currentLocationMarker.setPosition(currentLocation);
    }

}

I was experiencing the white line to the right on my iPad as well in horizontal position only. I was using a fixed-position div with a background set to 960px wide and z-index of -999. This particular div only shows up on an iPad due to a media query. Content was then placed into a 960px wide div wrapper. The answers provided on this page were not helping in my case. To fix the white stripe issue I changed the width of the content wrapper to 958px. Voilá. No more white right white stripe on the iPad in horizontal position.

I just experienced the same problem.

It may be an occlusion in the instructions regarding how to install (or upgrade) Android Studio with all the SDK Tools which both you and I missed or possibly a bug created by a new release of Studio which does not follow the same file conventions as the older versions. I lean towards the latter since many of the SO posts on this topic seems to point to an ANDROID_PATH with a folder called android-sdk which does not appear in the latest (2.3.0.8) version.

There appears to be a workaround though, which I just got to work on my machine. Here's what I did:

• Download tools_r25.2.3-windows.zip from Android Downloads.

• Extracted zip on desktop

• Replaced C:\Users\username\AppData\Local\Android\sdk\tools with extracted sub-folder tools/

• In project folder:

  $ cordova platforms remove android
  $ cordova platforms add android

You may also need to force remove the node_modules in android. Hopefully this helps.

The standard way, which has already been proposed several times is:

for (var name in myObject) {
  alert(name);
}

However Internet Explorer 6, 7 and 8 have a bug in the JavaScript interpreter, which has the effect that some keys are not enumerated. If you run this code:

var obj = { toString: 12};
for (var name in obj) {
  alert(name);
}

If will alert "12" in all browsers except IE. IE will simply ignore this key. The affected key values are:

• isPrototypeOf
• hasOwnProperty
• toLocaleString
• toString
• valueOf

To be really safe in IE you have to use something like:

for (var key in myObject) {
  alert(key);
}

var shadowedKeys = [
  "isPrototypeOf",
  "hasOwnProperty",
  "toLocaleString",
  "toString",
  "valueOf"
];
for (var i=0, a=shadowedKeys, l=a.length; i<l; i++) {
  if map.hasOwnProperty(a[i])) {
    alert(a[i]);
  }
}

The good news is that EcmaScript 5 defines the Object.keys(myObject) function, which returns the keys of an object as array and some browsers (e.g. Safari 4) already implement it.

Yes:

float[] values = {0.1f, 0.2f, 0.3f};

This syntax is only permissible in an initializer. You cannot use it in an assignment, where the following is the best you can do:

values = new float[3];

or

values = new float[] {0.1f, 0.2f, 0.3f};

Trying to find a reference in the language spec for this, but it's as unreadable as ever. Anyone else find one?

Laravel 5

This is working for me (i use laravel 5.6).

$collection = MyModel::all()->groupBy('column');

If you want to convert the collection to plain php array, you can use toArray()

$array = MyModel::all()->groupBy('column')->toArray();

To Access the Camera and take pictures and set ImageView on Android

You have to use Uri file = Uri.fromFile(getOutputMediaFile()); for marshmallow.

Use below link to get path

https://androidkennel.org/android-camera-access-tutorial/

Use RxCpp,

std::cout << "Waiting..." << std::endl;
auto values = rxcpp::observable<>::timer<>(std::chrono::seconds(1));
values.subscribe([](int v) {std::cout << "Called after 1s." << std::endl;});

You can use the "User-Defined Language" option available at the notepad++. You do not need to do the xml-based hacks, where the formatting would be available only in the searched window, with the formatting rules.

Sample for your reference here.

On Windows 10, to create the virtual environment, I replace "pip mkvirtualenv myproject" by "mkvirtualenv myproject" and that works well.

No need to add new plugin in pom.xml. Just run this command

mvn org.codehaus.mojo:exec-maven-plugin:1.5.0:java -Dexec.mainClass="com.example.Main" | grep -Ev '(^\[|Download\w+:)' 

See the maven exec plugin for more usage.

STATIC_ROOT

The absolute path to the directory where ./manage.py collectstatic will collect static files for deployment. Example: STATIC_ROOT="/var/www/example.com/static/"

now the command ./manage.py collectstatic will copy all the static files(ie in static folder in your apps, static files in all paths) to the directory /var/www/example.com/static/. now you only need to serve this directory on apache or nginx..etc.

STATIC_URL

The URL of which the static files in STATIC_ROOT directory are served(by Apache or nginx..etc). Example: /static/ or http://static.example.com/

If you set STATIC_URL = 'http://static.example.com/', then you must serve the STATIC_ROOT folder (ie "/var/www/example.com/static/") by apache or nginx at url 'http://static.example.com/'(so that you can refer the static file '/var/www/example.com/static/jquery.js' with 'http://static.example.com/jquery.js')

Now in your django-templates, you can refer it by:

{% load static %}
<script src="{% static "jquery.js" %}"></script>

which will render:

<script src="http://static.example.com/jquery.js"></script>

you can use this trick :

String s = "p";

char c = s.charAt(0);

Here's a solution with robocopy which copies the content of Folder1 into Folder2 going trough all subdirectories and automatically overwriting the files with the same name:

robocopy C:\Folder1 C:\Folder2 /COPYALL /E /IS /IT

Here:

/COPYALL copies all file information
/E copies subdirectories including empty directories
/IS includes the same files
/IT includes modified files with the same name

For more parameters see the official documentation: https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/robocopy

Note: it can be necessary to run the command as administrator, because of the argument /COPYALL. If you can't: just get rid of it.

Hope this helps somebody!

I have seen many answers to this question and found some answer is lengthy and some answer is a little bit wrong. I have created my own code by using the above IDs and class.

$('#ckbCheckAll').click(function(){
        if($(this).prop("checked")) {
            $(".checkBoxClass").prop("checked", true);
        } else {
            $(".checkBoxClass").prop("checked", false);
        }                
    });


    $('.checkBoxClass').click(function(){
        if($(".checkBoxClass").length == $(".checkBoxClass:checked").length) { 
            $("#ckbCheckAll").prop("checked", true);
        }else {
            $("#ckbCheckAll").prop("checked", false);            
        }
    });

In the above code, where user clicks on select all checkbox and all checkbox will be selected and vice versa and second code will work when the user selects checkbox one by one then select all checkbox will be checked or unchecked according to a number of checkboxes checked.

You can use following java code to get new inserted id.

ps = con.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
ps.setInt(1, quizid);
ps.setInt(2, userid);
ps.executeUpdate();

ResultSet rs = ps.getGeneratedKeys();
if (rs.next()) {
    lastInsertId = rs.getInt(1);
}

The spaceship method is useful when you define it in your own class and include the Comparable module. Your class then gets the >, < , >=, <=, ==, and between? methods for free.

class Card
  include Comparable
  attr_reader :value

  def initialize(value)
    @value = value
  end

  def <=> (other) #1 if self>other; 0 if self==other; -1 if self<other
    self.value <=> other.value
  end

end

a = Card.new(7)
b = Card.new(10)
c = Card.new(8)

puts a > b # false
puts c.between?(a,b) # true

# Array#sort uses <=> :
p [a,b,c].sort # [#<Card:0x0000000242d298 @value=7>, #<Card:0x0000000242d248 @value=8>, #<Card:0x0000000242d270 @value=10>]

There's actually a very little known class in the BCL for this purpose exactly: CommaDelimitedStringCollectionConverter. It serves as a middle ground of sorts between having a ConfigurationElementCollection (as in Richard's answer) and parsing the string yourself (as in Adam's answer).

For example, you could write the following configuration section:

public class MySection : ConfigurationSection
{
    [ConfigurationProperty("MyStrings")]
    [TypeConverter(typeof(CommaDelimitedStringCollectionConverter))]
    public CommaDelimitedStringCollection MyStrings
    {
        get { return (CommaDelimitedStringCollection)base["MyStrings"]; }
    }
}

You could then have an app.config that looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="foo" type="ConsoleApplication1.MySection, ConsoleApplication1"/>
  </configSections>
  <foo MyStrings="a,b,c,hello,world"/>
</configuration>

Finally, your code would look like this:

var section = (MySection)ConfigurationManager.GetSection("foo");
foreach (var s in section.MyStrings)
    Console.WriteLine(s); //for example

To complement the above answers, here is a small working example of a program that prints the current time and date, including milliseconds.

import java.text.SimpleDateFormat;
import java.util.Date;

public class test {
    public static void main(String argv[]){
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
        Date now = new Date();
        String strDate = sdf.format(now);
        System.out.println(strDate);
    }
}

No need for jQuery. And it isn't necessary to open a new window. Protocols which doesn't return HTTP data to the browser (mailto:, irc://, magnet:, ftp:// (<- it depends how it is implemented, normally the browser has an FTP client built in)) can be queried in the same window without losing the current content. In your case:

function redirect()
{
    window.location.href = "mailto:[email protected]";
}
<body onload="javascript: redirect();">

Or just directly

<body onload="javascript: window.location.href='mailto:[email protected]';">

SSLHandshakeException can be resolved 2 ways.

1. Incorporating SSL

   • Get the SSL (by asking the source system administrator, can also be downloaded by openssl command, or any browsers downloads the certificates)

   • Add the certificate into truststore (cacerts) located at JRE/lib/security

   • provide the truststore location in vm arguments as "-Djavax.net.ssl.trustStore="

2. Ignoring SSL

   For this #2, please visit my other answer on another stackoverflow website: How to ingore SSL verification Ignore SSL Certificate Errors with Java

We can resolve this problem in Spring-Apache-tomcat environment by adding one single line in RequestInterceptor method -

//before the actual handler will be executed
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler)
throws Exception {

// Some logic

// below statement ensures IE trusts the page formatting and will render it acc. to IE 8 standard.
response.addHeader("X-UA-Compatible", "IE=8"); 

return true;
}

Reference from - How to create filter and modify response header It covers how we can resolve this problem via a RequestInterceptor (Spring).

If array is static allocated:

size_t size = sizeof(arr) / sizeof(int);

if array is dynamic allocated(heap):

int *arr = malloc(sizeof(int) * size);

where variable size is a dimension of the arr.

I wrote a small command-line based Python script based on pesterfesh that does exactly this:

https://github.com/hay/xml2json

Another date format

select datediff(day,'20110101','20110301')

Just use the unary minus operator:

int x = 5;
...
x = -x; // Here's the mystery library function - the single character "-"

Java has two minus operators:

• the familiar arithmetic version (eg 0 - x), and
• the unary minus operation (used here), which negates the (single) operand

This compiles and works as expected.

I had a simmilar problem, but in my case I was put a row in the leading of the Listview, and it was consumming all the space, of course. I just had to take the Row out of the leading, and it was solved. I would recomend to check if the problem is a widget larger than its containner can have.

abort() sends the calling process the SIGABRT signal, this is how abort() basically works.

abort() is usually called by library functions which detect an internal error or some seriously broken constraint. For example malloc() will call abort() if its internal structures are damaged by a heap overflow.

The problem is that the change event fires only when focus is moved away from the input (e.g. someone clicks off the input or tabs out of it). Try using keyup instead:

$(document).ready(function() {
     $(':input[type="submit"]').prop('disabled', true);
     $('input[type="text"]').keyup(function() {
        if($(this).val() != '') {
           $(':input[type="submit"]').prop('disabled', false);
        }
     });
 });

Just hook up the onclick event:

<input id="button" type="submit" name="button" value="enter" onclick="myFunction();"/>

I checked all the answers around the web and the best one seemed to be: (actually it isn't)

<img src="image.png?cache=none">

at first.

However, if you add cache=none parameter (which is static "none" word), it doesn't effect anything, browser still loads from cache.

Solution to this problem was:

<img src="image.png?nocache=<?php echo time(); ?>">

where you basically add unix timestamp to make the parameter dynamic and no cache, it worked.

However, my problem was a little different: I was loading on the fly generated php chart image, and controlling the page with $_GET parameters. I wanted the image to be read from cache when the URL GET parameter stays the same, and do not cache when the GET parameters change.

To solve this problem, I needed to hash $_GET but since it is array here is the solution:

$chart_hash = md5(implode('-', $_GET));
echo "<img src='/images/mychart.png?hash=$chart_hash'>";

Edit:

Although the above solution works just fine, sometimes you want to serve the cached version UNTIL the file is changed. (with the above solution, it disables the cache for that image completely) So, to serve cached image from browser UNTIL there is a change in the image file use:

echo "<img src='/images/mychart.png?hash=" . filemtime('mychart.png') . "'>";

filemtime() gets file modification time.

you cannot set this in javascript, you have to do this with html/css:

<style type="text/css" media="print">
  @page { size: landscape; }
</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

As I was facing this issue minutes ago, in case you are trying to open an existing project in an environment with a newer JDK, make sure you pdate the JDK version in Project Properties -> Project Facets -> Java.

This is a modified version of Tim Post's method; I used /dev/tty instead of /dev/stdout. I don't know why it doesn't work with stdout (which is a link to /proc/self/fd/1):

freopen("log.txt","w",stdout);
...
...
freopen("/dev/tty","w",stdout);

By using /dev/tty the output is redirected to the terminal from where the app was launched.

Hope this info is useful.

I have a function and stored it in a service so i can use it all over my app:

Service:

app.service('SplitArrayService', function () {
return {
    SplitArray: function (array, columns) {
        if (array.length <= columns) {
            return [array];
        };

        var rowsNum = Math.ceil(array.length / columns);

        var rowsArray = new Array(rowsNum);

        for (var i = 0; i < rowsNum; i++) {
            var columnsArray = new Array(columns);
            for (j = 0; j < columns; j++) {
                var index = i * columns + j;

                if (index < array.length) {
                    columnsArray[j] = array[index];
                } else {
                    break;
                }
            }
            rowsArray[i] = columnsArray;
        }
        return rowsArray;
    }
}

});

Controller:

$scope.rows   = SplitArrayService.SplitArray($scope.images, 3); //im splitting an array of images into 3 columns

Markup:

 <div class="col-sm-12" ng-repeat="row in imageRows">
     <div class="col-sm-4" ng-repeat="image in row">
         <img class="img-responsive" ng-src="{{image.src}}">
     </div>
 </div>

The ZIP file format does allow to store the permission bits, but Windows programs normally ignore it. The zip utility on Cygwin however does preserve the x bit, just like it does on Linux. If you do not want to use Cygwin, you can take a source code and tweak it so that all *.sh files get the executable bit set. Or write a script like explained here

For me it worked like I had images in icons folder under src and I wrote below code.

new ImageIcon(getClass().getResource("/icons/rsz_measurment_01.png"));

One more answer: since you said you need to validate files you are generating (writing), you might want to validate content while you are writing, instead of first writing, then reading back for validation. You can probably do that with JDK API for Xml validation, if you use SAX-based writer: if so, just link in validator by calling 'Validator.validate(source, result)', where source comes from your writer, and result is where output needs to go.

Alternatively if you use Stax for writing content (or a library that uses or can use stax), Woodstox can also directly support validation when using XMLStreamWriter. Here's a blog entry showing how that is done:

I thought I had misunderstood but I was right. In this scenario, it will be ActiveWorkbook.Path

But the main issue was not here. The problem was with these 2 lines of code

strFile = Dir(strPath & "*.csv")

Which should have written as

strFile = Dir(strPath & "\*.csv")

and

With .QueryTables.Add(Connection:="TEXT;" & strPath & strFile, _

Which should have written as

With .QueryTables.Add(Connection:="TEXT;" & strPath & "\" & strFile, _

Solution:
Instead of using setHeader method I have used addHeader.

response.addHeader("Access-Control-Allow-Origin", "*");

* in above line will allow access to all domains, For allowing access to specific domain only:

response.addHeader("Access-Control-Allow-Origin", "http://www.example.com");

Despite its very explicit and forceful description, RETURN did not work for me inside a stored procedure (to skip further execution). I had to modify the condition logic. Happens on both SQL 2008, 2008 R2:

create proc dbo.prSess_Ins
(
    @sSessID    varchar( 32 )
,   @idSess     int out
)
as
begin
    set nocount on

    select  @id=    idSess
        from    tbSess
        where   sSessID = @sSessID

    if  @idSess > 0 return  -- exit sproc here

    begin   tran
        insert  tbSess  ( sSessID ) values  ( @sSessID )
        select  @idSess=    scope_identity( )
    commit
end

had to be changed into:

    if  @idSess is null
    begin
        begin   tran
            insert  tbSess  ( sSessID ) values  ( @sSessID )
            select  @idSess=    scope_identity( )
        commit
    end

Discovered as a result of finding duplicated rows. Debugging PRINTs confirmed that @idSess had value greater than zero in the IF check - RETURN did not break execution!

There are a number of "is methods" on strings. islower() and isupper() should meet your needs:

>>> 'hello'.islower()
True

>>> [m for m in dir(str) if m.startswith('is')]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

Here's an example of how to use those methods to classify a list of strings:

>>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG']
>>> [word for word in words if word.islower()]
['quick', 'jumped', 'the']
>>> [word for word in words if word.isupper()]
['BROWN', 'OVER', 'DOG']
>>> [word for word in words if not word.islower() and not word.isupper()]
['The', 'Fox', 'Lazy']

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

• Divide and Conquer
  • They broke into non-overlapping sub-problems
  • Example: factorial numbers i.e. fact(n) = n*fact(n-1)

fact(5) = 5* fact(4) = 5 * (4 * fact(3))= 5 * 4 * (3 *fact(2))= 5 * 4 * 3 * 2 * (fact(1))

As we can see above, no fact(x) is repeated so factorial has non overlapping problems.

• Dynamic Programming
  • They Broke into overlapping sub-problems
  • Example: Fibonacci numbers i.e. fib(n) = fib(n-1) + fib(n-2)

fib(5) = fib(4) + fib(3) = (fib(3)+fib(2)) + (fib(2)+fib(1))

As we can see above, fib(4) and fib(3) both use fib(2). similarly so many fib(x) gets repeated. that's why Fibonacci has overlapping sub-problems.

• As a result of the repetition of sub-problem in DP, we can keep such results in a table and save computation effort. this is called as memoization

Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.

<a href="Controller/ActionMethod">
    <input type="button" value="Click Me" />
</a>

Adding parameters:

<a href="Controller/ActionMethod?userName=ted">
    <input type="button" value="Click Me" />
</a>

Adding parameters from a non-enumerated Model:

<a href="Controller/[email protected]">
    <input type="button" value="Click Me" />
</a>

You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!

Is it really a function call on the action attribute? or it should be on the onSUbmit attribute, because by convention action attribute needs a page/URL.

I think you should use AJAX with that,

There are plenty PHP AJAX Frameworks to choose from

ETC.

That's a half-open interval.

• A closed interval [a,b] includes the end points.
• An open interval (a,b) excludes them.

In your case the end-point at the start of the interval is included, but the end is excluded. So it means the interval "first1 <= x < last1".

Half-open intervals are useful in programming because they correspond to the common idiom for looping:

for (int i = 0; i < n; ++i) { ... } 

Here i is in the range [0, n).

def oneFunction(lists):
    category=random.choice(list(lists.keys()))
    word=random.choice(lists[category])
    return word

def anotherFunction():
    for letter in word:             
        print("_",end=" ")

Actually my problem was that the command line mvn utility wouldn't see the changes for some reason. I turned on the Auto-deploy in the Deployment Scanner and there was still no difference. HOWEVER... I was twiddling around with the Eclipse environment and because I had added a JBoss server for it's Servers window I discovered I had the ability to "Add or Remove..." modules in my workspace. Once the project was added whenever I made a change to code the code change was detected by the Deployment Scanner and JBoss went thru the cycle of updating code!!! Works like a charm.

Here are the steps necessary to set this up;

First if you haven't done so add your JBoss Server to your Eclipse using File->New->Other->Server then go thru the motions of adding your JBoss AS 7 server. Being sure to locate the directory that you are using.

Once added, look down near the bottom of Eclipse to the "Servers" tab. You should see your JBoss server. Highlight it and look for "Add or Remove...". From there you should see your project.

Once added, make a small change to your code and watch JBoss go to town hot deploying for you.

var assoc_pagine = new Array();
assoc_pagine["home"]=0;

Don't use an Array for this. Arrays are for numerically-indexed lists. Just use a plain Object ({}).

What you are thinking of with the 'undefined' string is probably this:

if (typeof assoc_pagine[key]!=='undefined')

This is (more or less) the same as saying

if (assoc_pagine[key]!==undefined)

However, either way this is a bit ugly. You're dereferencing a key that may not exist (which would be an error in any more sensible language), and relying on JavaScript's weird hack of giving you the special undefined value for non-existent properties.

This also doesn't quite tell you if the property really wasn't there, or if it was there but explicitly set to the undefined value.

This is a more explicit, readable and IMO all-round better approach:

if (key in assoc_pagine)

Based on http://dev.mysql.com/doc/refman/5.0/en/create-table-select.html

What about:

Create Table New_Users Select * from Old_Users Where 1=2;

and if that doesn't work, just select a row and truncate after creation:

Create table New_Users select * from Old_Users Limit 1;
Truncate Table New_Users;

EDIT:

I noticed your comment below about needing indexes, etc. Try:

show create table old_users;
#copy the output ddl statement into a text editor and change the table name to new_users
#run the new query
insert into new_users(id,name...) select id,name,... form old_users group by id;

That should do it. It appears that you are doing this to get rid of duplicates? In which case you may want to put a unique index on id. if it's a primary key, this should already be in place. You can either:

#make primary key
alter table new_users add primary key (id);
#make unique
create unique index idx_new_users_id_uniq on new_users (id);

To select a checkbox, use the "WebElement" class.

To operate on a drop-down list, use the "Select" class.

Can't you use the first selector ?

something like: tr:first

I have similar problem but I solved it by removing all the foreign key in my Postgresql

// Copied from MSDN, the second point of non-clustered index is not clearly mentioned in the other answers.

Clustered

• Clustered indexes sort and store the data rows in the table or view based on their key values. These are the columns included in the index definition. There can be only one clustered index per table, because the data rows themselves can be stored in only one order.
• The only time the data rows in a table are stored in sorted order is when the table contains a clustered index. When a table has a clustered index, the table is called a clustered table. If a table has no clustered index, its data rows are stored in an unordered structure called a heap.

Nonclustered

• Nonclustered indexes have a structure separate from the data rows. A nonclustered index contains the nonclustered index key values and
  each key value entry has a pointer to the data row that contains the key value.
• The pointer from an index row in a nonclustered index to a data row is called a row locator. The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table. For a heap, a row locator is a pointer to the row. For a clustered table, the row locator is the clustered index key.

I concur with the Dragon Book reference; IMO, it is the definitive guide to compiler construction. Get ready for some hardcore theory, though.

If you want a book that is lighter on theory, Game Scripting Mastery might be a better book for you. If you are a total newbie at compiler theory, it provides a gentler introduction. It doesn't cover more practical parsing methods (opting for non-predictive recursive descent without discussing LL or LR parsing), and as I recall, it doesn't even discuss any sort of optimization theory. Plus, instead of compiling to machine code, it compiles to a bytecode that is supposed to run on a VM that you also write.

It's still a decent read, particularly if you can pick it up for cheap on Amazon. If you only want an easy introduction into compilers, Game Scripting Mastery is not a bad way to go. If you want to go hardcore up front, then you should settle for nothing less than the Dragon Book.

It seems that MySQL process is running hence you are unable to use the port. You can check the running MySQL process using following command:

ps auxf | grep mysql

If you get any MySQL process kill that process ID using kill -9 PID and then try to start MySQL.

No installation needed. Just drop the file.

You can do as the example on Mozilla docs:

 document.cookie = "someCookieName=true; expires=Fri, 31 Dec 9999 23:59:59 GMT";

P.S

Of course, there will be an issue if humanity still uses your code on the first minute of year 10000 :)

This typed error-message also shows while an if-statement comparison is done where there is an array and for example a bool or int. See for example:

... code snippet ...

if dataset == bool:
    ....

... code snippet ...

This clause has dataset as array and bool is euhm the "open door"... True or False.

In case the function is wrapped within a try-statement you will receive with except Exception as error: the message without its error-type:

The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

This answers improves on Rashmi Pandit's answer, which is in a way better than the rest because that it seems to completely resolve the exact problem detailed in the question.

The bad part is that is inefficient and not uses the IgnoreCase option consistently.

Inefficient part is because regex can be expensive to construct and execute, and in that answer it could have been constructed just once (calling Regex.IsMatch was just constructing the regex again behind the scene). And Match method could have been called only once and stored in a variable and then linkand name should call Result from that variable.

And the IgnoreCase option was only used in the Match part but not in the Regex.IsMatch part.

I also moved the Regex definition outside the method in order to construct it just once (I think is the sensible approach if we are storing that the assembly with the RegexOptions.Compiled option).

private static Regex hrefRegex = new Regex("<td>\\s*<a\\s*href\\s*=\\s*(?:\"(?<link>[^\"]*)\"|(?<link>\\S+))\\s*>(?<name>.*)\\s*</a>\\s*</td>",  RegexOptions.IgnoreCase | RegexOptions.Compiled);

public static bool TryGetHrefDetails(string htmlTd, out string link, out string name)
{
    var matches = hrefRegex.Match(htmlTd);
    if (matches.Success)
    {
        link = matches.Result("${link}");
        name = matches.Result("${name}");
        return true;
    }
    else
    {
        link = null;
        name = null;
        return false;
    }
}

1. Right-click on project
2. Go to properties => project factes
3. Click on runtime tab
4. Check the box of the server
5. Then ok

Close the eclipse and start the server you will able to see and run the project.

in gradle.properties, you can even delete

org.gradle.jvmargs=-Xmx1536m

such lines or comment them out. Let android studio decide for it. When I ran into this same problem, none of above solutions worked for me. Commenting out this line in gradle.properties helped in solving that error.

Actually I don't know you want to this.

try this

INSERT INTO my_table (my_column)
SELECT
    (random() * 10) + 1
;

you can try this (I don't have sql server here today so I can't verify syntax, sorry)

select attributeName
  from tableName
 where CONVERT(varchar,attributeName,101) BETWEEN '03/01/2009' AND '03/31/2009'
   and CONVERT(varchar, attributeName,108) BETWEEN '06:00:00' AND '22:00:00'
   and DATEPART(day,attributeName) BETWEEN 2 AND 4

This method lets TextField to finish all processing (copy/paste/undo safe). Does not require to extend classes and allows you to decide what to do with new text after every change (to push it to logic, or turn back to previous value, or even to modify it).

  // fired by every text property change
textField.textProperty().addListener(
  (observable, oldValue, newValue) -> {
    // Your validation rules, anything you like
      // (! note 1 !) make sure that empty string (newValue.equals("")) 
      //   or initial text is always valid
      //   to prevent inifinity cycle
    // do whatever you want with newValue

    // If newValue is not valid for your rules
    ((StringProperty)observable).setValue(oldValue);
      // (! note 2 !) do not bind textProperty (textProperty().bind(someProperty))
      //   to anything in your code.  TextProperty implementation
      //   of StringProperty in TextFieldControl
      //   will throw RuntimeException in this case on setValue(string) call.
      //   Or catch and handle this exception.

    // If you want to change something in text
      // When it is valid for you with some changes that can be automated.
      // For example change it to upper case
    ((StringProperty)observable).setValue(newValue.toUpperCase());
  }
);

For your case just add this logic inside. Works perfectly.

   if (newValue.equals("")) return; 
   try {
     Integer i = Integer.valueOf(newValue);
     // do what you want with this i
   } catch (Exception e) {
     ((StringProperty)observable).setValue(oldValue);
   }

This is the classic "unicode issue". I believe that explaining this is beyond the scope of a StackOverflow answer to completely explain what is happening.

It is well explained here.

In very brief summary, you have passed something that is being interpreted as a string of bytes to something that needs to decode it into Unicode characters, but the default codec (ascii) is failing.

The presentation I pointed you to provides advice for avoiding this. Make your code a "unicode sandwich". In Python 2, the use of from __future__ import unicode_literals helps.

Update: how can the code be fixed:

OK - in your variable "source" you have some bytes. It is not clear from your question how they got in there - maybe you read them from a web form? In any case, they are not encoded with ascii, but python is trying to convert them to unicode assuming that they are. You need to explicitly tell it what the encoding is. This means that you need to know what the encoding is! That is not always easy, and it depends entirely on where this string came from. You could experiment with some common encodings - for example UTF-8. You tell unicode() the encoding as a second parameter:

source = unicode(source, 'utf-8')

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

That's not possible using the built-in Array.prototype.map. However, you could use a simple for-loop instead, if you do not intend to map any values:

var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
  if (myArray[i] < 10) {
    hasValueLessThanTen = true;
    break;
  }
}

Or, as suggested by @RobW, use Array.prototype.some to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:

var hasValueLessThanTen = myArray.some(function (val) { 
  return val < 10;
});

Simply use

BluetoothAdapter.getDefaultAdapter().getName()

If you are trying to run some dynamically generated JavaScript, you would be slightly better off by using eval. However, JavaScript is such a dynamic language that you really should not have a need for that.

If the script is static, then Rocket's getScript-suggestion is the way to go.

In case anyone's interested, here's my solution to the problem. It works completely independently of the Draggable objects, by using events on the Droppable object instead. It works quite well:

$(function() {
    $(".draggable").draggable({
        opacity: .4,
        create: function(){$(this).data('position',$(this).position())},
        cursor:'move',
        start:function(){$(this).stop(true,true)}
    });

    $('.active').droppable({
        over: function(event, ui) {
            $(ui.helper).unbind("mouseup");
        },
        drop:function(event, ui){
            snapToMiddle(ui.draggable,$(this));
        },
        out:function(event, ui){
            $(ui.helper).mouseup(function() {
                snapToStart(ui.draggable,$(this)); 
            });
        }
    });
}); 

function snapToMiddle(dragger, target){
    var topMove = target.position().top - dragger.data('position').top + (target.outerHeight(true) - dragger.outerHeight(true)) / 2;
    var leftMove= target.position().left - dragger.data('position').left + (target.outerWidth(true) - dragger.outerWidth(true)) / 2;
    dragger.animate({top:topMove,left:leftMove},{duration:600,easing:'easeOutBack'});
}
function snapToStart(dragger, target){
    dragger.animate({top:0,left:0},{duration:600,easing:'easeOutBack'});
}

If you are using JavaScript to render then use escape_JavaScript("<%=render partial: partial_name, locals=>{@newval=>@oldval}%>");

Remove the RVM load script from /.bash_rc or /.zsh_rc, then use:

rm -rf /.rvm

Or:

rvm implode

this is best solution for me :)

$i=0;
foreach() if ($i < yourlimitnumber) {

$i +=1;
}

Yes, it is. Declare parameter as so:

@Sort varchar(50) = NULL

Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).

Just try $('.handle').css('left', '300px');

But what if the container is not the viewport (body)?

This question is asked in a comment by Alex under the accepted answer.

That fact does not mean vw cannot be used to some extent to size for that container. Now to see any variation at all one has to be assuming that the container in some way is flexible in size. Whether through a direct percentage width or through being 100% minus margins. The point becomes "moot" if the container is always set to, let's say, 200px wide--then just set a font-size that works for that width.

Example 1

With a flexible width container, however, it must be realized that in some way the container is still being sized off the viewport. As such, it is a matter of adjusting a vw setting based off that percentage size difference to the viewport, which means taking into account the sizing of parent wrappers. Take this example:

div {
    width: 50%;
    border: 1px solid black;
    margin: 20px;
    font-size: 16px;
    /* 100 = viewport width, as 1vw = 1/100th of that
       So if the container is 50% of viewport (as here)
       then factor that into how you want it to size.
       Let's say you like 5vw if it were the whole width,
       then for this container, size it at 2.5vw (5 * .5 [i.e. 50%])
    */
    font-size: 2.5vw;
}

Assuming here the div is a child of the body, it is 50% of that 100% width, which is the viewport size in this basic case. Basically, you want to set a vw that is going to look good to you. As you can see in my comment in the above CSS content, you can "think" through that mathematically with respect to the full viewport size, but you don't need to do that. The text is going to "flex" with the container because the container is flexing with the viewport resizing. UPDATE: here's an example of two differently sized containers.

Example 2

You can help ensure viewport sizing by forcing the calculation based off that. Consider this example:

html {width: 100%;} /* Force 'html' to be viewport width */
body {width: 150%; } /* Overflow the body */

div {
    width: 50%;
    border: 1px solid black;
    margin: 20px;
    font-size: 16px;
    /* 100 = viewport width, as 1vw = 1/100th of that
       Here, the body is 150% of viewport, but the container is 50%
       of viewport, so both parents factor  into how you want it to size.
       Let's say you like 5vw if it were the whole width,
       then for this container, size it at 3.75vw
       (5 * 1.5 [i.e. 150%]) * .5 [i.e. 50%]
    */
    font-size: 3.75vw;
}

The sizing is still based off viewport, but is in essence set up based off the container size itself.

Should Size of the Container Change Dynamically...

If the sizing of the container element ended up changing dynamically its percentage relationship either via @media breakpoints or via JavaScript, then whatever the base "target" was would need recalculation to maintain the same "relationship" for text sizing.

Take example #1 above. If the div was switched to 25% width by either @media or JavaScript, then at the same time, the font-size would need to adjust in either the media query or by JavaScript to the new calculation of 5vw * .25 = 1.25. This would put the text size at the same size it would have been had the "width" of the original 50% container been reduced by half from viewport sizing, but has now been reduced due to a change in its own percentage calculation.

A Challenge

With the CSS3 calc() function in use, it would become difficult to adjust dynamically, as that function does not work for font-size purposes at this time. So you could not do a pure CSS 3 adjustment if your width is changing on calc(). Of course, a minor adjustment of width for margins may not be enough to warrant any change in font-size, so it may not matter.

Use Internet Explorer 8. Then Try the developer tool.. You can debug based on IE 7 also in compatibility mode

Wrapping the existing formula in IFERROR will not achieve:

the average of cells that contain non-zero, non-blank values.

I suggest trying:

=if(ArrayFormula(isnumber(K23:M23)),AVERAGEIF(K23:M23,"<>0"),"")

You have to run pip.exe from the command prompt on my computer. I type C:/Python27/Scripts/pip2.exe install numpy

There's a note on top of the docs:

Note: The Google Web Search API has been officially deprecated as of November 1, 2010. It will continue to work as per our deprecation policy, but the number of requests you may make per day will be limited. Therefore, we encourage you to move to the new Custom Search API.

The deprecation policy says that they will continue to run the API for 3 years. So if you already have an application that uses the old API, you don't have to rush to change things just yet. If you're writing a new application, use the Custom Search API. See my answer here for how to do this in Python, but the idea's the same for any language.

Math.sqrt returns a double so you'll have to cast it to int as well

distance = (int)Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2));

In powershell you should use ${pwd} vs $(pwd)

This is a subjective opinion, but I think a text editor shouldn't do everything and the kitchen sink. I prefer lightweight flexible and powerful (in their specialized fields) editors. Although being mostly a Windows user, I like the Unix philosophy of having lot of specialized tools that you can pipe together (like the UnxUtils) rather than a monster doing everything, but not necessarily as you would like it!

Find in files is on the border of these extra features, but useful when you can double-click on a found line to open the file at the right line. Note that initially, in SciTE it was just a Tools call to grep or equivalent!
FTP is very close to off topic, although it can be seen as an extended open/save dialog.
Replace in files is too much IMO: it is dangerous (you can mess lot of files at once) if you have no preview, etc. I would rather use a specialized tool I chose, perhaps among those in Multi line search and replace tool.

To answer the question, looking at N++, I see a Run menu where you can launch any tool, with assignment of a name and shortcut key. I see also Plugins > NppExec, which seems able to launch stuff like sed (not tried it).

These preferences appear to have changed since @alex-dima's answer.

Changing settings

From menu choose: File -> Preferences -> Settings -> User/Workspace Settings. Filter default settings to search.

You can modify the search.exclude setting (copy from default setting to your user or workspace settings). That will apply only to searches. Note that settings from files.exclude will be automatically applied.

If the settings don't work:

1. Make sure you didn't turn the search exclusion off. In the search area, expand the "files to exclude" input box and make sure that the gear icon is selected.

2. You might also need to Clear Editor History (See: https://github.com/Microsoft/vscode/issues/6502).

Example settings

For example, I am developing an EmberJS application which saves thousands of files under the tmp directory.

If you select WORKSPACE SETTINGS on the right side of the search field, the search exclusion will only be applied to this particular project. And a corresponding .vscode folder will be added to the root folder containing settings.json.

This is my example settings:

{
    // ...
    "search.exclude": {
        "**/.git": true,
        "**/node_modules": true,
        "**/bower_components": true,
        "**/tmp": true
    },
    // ...
}

Note: Include a ** at the beginning of any search exclusion to cover the search term over any folders and sub-folders.

Picture of search before updating settings:

Before updating the settings the search results are a mess.

After updating the settings the search results are exactly what I want.

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

I am assuming you are using java 7, thus you get a compiler warning, when you don't close the resource you should close your scanner usually in a finally block.

Scanner scanner = null;
try {
    scanner = new Scanner(System.in);
    //rest of the code
}
finally {
    if(scanner!=null)
        scanner.close();
}

Or even better: use the new Try with resource statement:

try(Scanner scanner = new Scanner(System.in)){
    //rest of your code
}

I wanted similar richness in colors for HTML elements, I was surprised to find that CSS now supports hsl() colors, so a full solution for me is below:

Also see How to automatically generate N "distinct" colors? for more alternatives more similar to this.

function colorByHashCode(value) {_x000D_
    return "<span style='color:" + value.getHashCode().intToHSL() + "'>" + value + "</span>";_x000D_
}_x000D_
String.prototype.getHashCode = function() {_x000D_
    var hash = 0;_x000D_
    if (this.length == 0) return hash;_x000D_
    for (var i = 0; i < this.length; i++) {_x000D_
        hash = this.charCodeAt(i) + ((hash << 5) - hash);_x000D_
        hash = hash & hash; // Convert to 32bit integer_x000D_
    }_x000D_
    return hash;_x000D_
};_x000D_
Number.prototype.intToHSL = function() {_x000D_
    var shortened = this % 360;_x000D_
    return "hsl(" + shortened + ",100%,30%)";_x000D_
};_x000D_
_x000D_
document.body.innerHTML = [_x000D_
  "javascript",_x000D_
  "is",_x000D_
  "nice",_x000D_
].map(colorByHashCode).join("<br/>");

span {_x000D_
  font-size: 50px;_x000D_
  font-weight: 800;_x000D_
}

In HSL its Hue, Saturation, Lightness. So the hue between 0-359 will get all colors, saturation is how rich you want the color, 100% works for me. And Lightness determines the deepness, 50% is normal, 25% is dark colors, 75% is pastel. I have 30% because it fit with my color scheme best.

If you want to do this in two steps, rather than the three of REVERSE-STUFF-REVERSE, you can have your list separator be one or two spaces. Then use RTRIM to trim the trailing spaces, and REPLACE to replace the double spaces with ','

select REPLACE(RTRIM('a  b  c  d  '),'  ', ', ')

However, this is not a good idea if your original string can contain internal spaces.

Not sure about performance. Each REVERSE creates a new copy of the string, but STUFF is a third faster than REPLACE.

Keeping in mind the points made in @John Woo's comment/link above, this is how I typically would handle it:

SELECT t1.ID, t1.Name 
FROM   Table1 t1
WHERE  NOT EXISTS (
    SELECT TOP 1 NULL
    FROM Table2 t2
    WHERE t1.ID = t2.ID
)

One more good point here is to use @JsonFilter. Some details here http://wiki.fasterxml.com/JacksonFeatureJsonFilter

These two settings worked for me to upload 1GB mp4 videos.

<system.web>
    <httpRuntime maxRequestLength="2097152" requestLengthDiskThreshold="2097152" executionTimeout="240"/>
</system.web>
<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="2147483648" />
        </requestFiltering>
    </security>
</system.webServer>

Using subList(30, 38); will fail because max index 38 is not available in list, so its not possible.

Only way may be before asking for the sublist, you explicitly determine the max index using list size() method.

for example, check size, which returns 35, so call sublist(30, size());

OR

COPIED FROM pb2q comment

dataList = dataList.subList(30, 38 > dataList.size() ? dataList.size() : 38);

In pseudocode:

split it by colon
seconds = 3600 * HH + 60 * MM + SS

Each argument passed via command line can be accessed with: Wscript.Arguments.Item(0) Where the zero is the argument number: ie, 0, 1, 2, 3 etc.

So in your code you could have:

strFolder = Wscript.Arguments.Item(0) 

Set FSO = CreateObject("Scripting.FileSystemObject")
Set File = FSO.OpenTextFile(strFolder, 2, True)
File.Write "testing"
File.Close
Set File = Nothing
Set FSO = Nothing
Set workFolder = Nothing

Using wscript.arguments.count, you can error trap in case someone doesn't enter the proper value, etc.

MS Technet examples

Pushing and popping registers are behind the scenes equivalent to this:

push reg   <= same as =>      sub  $8,%rsp        # subtract 8 from rsp
                              mov  reg,(%rsp)     # store, using rsp as the address

pop  reg    <= same as=>      mov  (%rsp),reg     # load, using rsp as the address
                              add  $8,%rsp        # add 8 to the rsp

Note this is x86-64 At&t syntax.

Used as a pair, this lets you save a register on the stack and restore it later. There are other uses, too.

Not knowing how the OP happened to have {" String", "Tom Selleck "," Fish "} in an array in the first place (6 years ago), I thought I'd share what I ended up with.

My array is the result of using split on a string which might have extra spaces around delimiters. My solution was to address this at the point of the split. My code follows. After testing, I put splitWithTrim() in my Utils class of my project. It handles my use case; you might want to consider what sorts of strings and delimiters you might encounter if you decide to use it.

public class Test {
    public static void main(String[] args) {
        test(" abc def  ghi   jkl ", " ");
        test("  abc; def  ;ghi  ; jkl; ", ";");
    }

    public static void test(String str, String splitOn) {
        System.out.println("Splitting \"" + str + "\" on \"" + splitOn + "\"");
        String[] parts = splitWithTrim(str, splitOn);
        for (String part : parts) {
            System.out.println("(" + part + ")");
        }
    }

    public static String[] splitWithTrim(String str, String splitOn) {
        if (splitOn.equals(" ")) {
            return str.trim().split(" +");
        } else {
            return str.trim().split(" *" + splitOn + " *");
        }
    }
}

Output of running the test application is:

Splitting " abc def  ghi   jkl " on " "
(abc)
(def)
(ghi)
(jkl)
Splitting "  abc; def  ;ghi  ; jkl; " on ";"
(abc)
(def)
(ghi)
(jkl)

ToString("X2") prints the input in Hexadecimal

Additional thoughts :

Ramdisk - setting the temp drive MySQL uses as a RAM disk, very easy to set up.

memcache - memcache server is easy to set up, use it to store the results of your queries for X amount of time.

For How do I change the overall colors (background and font)?

For MAC : goto Sublime text -> Preferences -> color scheme

using Android KTX library u can parse easily

val uri = myUriString.toUri()

I am not sure but I think there is one command using which you can copy the schema of database into new database, once you have done this you can delete the old database and after this you can again copy the database schema to the old name.

<form method='post' id='userform' action='thisform.php'> <tr>
    <td>Trouble Type</td>
    <td>
    <input type='checkbox' name='checkboxvar[]' value='Option One'>1<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Two'>2<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Three'>3
    </td> </tr> </table> <input type='submit' class='buttons'> </form>

<?php 
if (isset($_POST['checkboxvar'])) 
{
    print_r($_POST['checkboxvar']); 
}
?>

You pass the form name as an array and then you can access all checked boxes using the var itself which would then be an array.

To echo checked options into your email you would then do this:

echo implode(',', $_POST['checkboxvar']); // change the comma to whatever separator you want

Please keep in mind you should always sanitize your input as needed.

For the record, official docs on this exist: http://php.net/manual/en/faq.html.php#faq.html.arrays

I would suggest to use gradle.build file.

1. Add a src/androidTest/java directory for the tests (Like Chris starts to explain)

2. Open gradle.build file and specify there:

   android {
   
       compileSdkVersion rootProject.compileSdkVersion
       buildToolsVersion rootProject.buildToolsVersion
   
       sourceSets {
   
           androidTest {
               java.srcDirs = ['androidTest/java']
           }
       }
   }
   

3. Press "Sync Project with Gradle file" (at the top panel). You should see now a folder "java" (inside "androidTest") is a green color.

4. Now You are able to create there any test files and execute they.

Try assigning a value to $aug1 before use it in if[] statements; the error message will disappear afterwards.

This is the best and easiest code:

public class test
{
    public static void main(String str[])
    {
        String jsonString = "{\"stat\": { \"sdr\": \"aa:bb:cc:dd:ee:ff\", \"rcv\": \"aa:bb:cc:dd:ee:ff\", \"time\": \"UTC in millis\", \"type\": 1, \"subt\": 1, \"argv\": [{\"type\": 1, \"val\":\"stackoverflow\"}]}}";
        JSONObject jsonObject = new JSONObject(jsonString);
        JSONObject newJSON = jsonObject.getJSONObject("stat");
        System.out.println(newJSON.toString());
        jsonObject = new JSONObject(newJSON.toString());
        System.out.println(jsonObject.getString("rcv"));
       System.out.println(jsonObject.getJSONArray("argv"));
    }
}

The library definition of the json files are given here. And it is not same libraries as posted here, i.e. posted by you. What you had posted was simple json library I have used this library.

You can download the zip. And then create a package in your project with org.json as name. and paste all the downloaded codes there, and have fun.

I feel this to be the best and the most easiest JSON Decoding.

Secure commands will not allow this, and rightly so, I'm afraid - it's a security hole you could drive a truck through.

If your command does not allow it using input redirection, or a command-line parameter, or a configuration file, then you're going to have to resort to serious trickery.

Some applications will actually open up /dev/tty to ensure you will have a hard time defeating security. You can get around them by temporarily taking over /dev/tty (creating your own as a pipe, for example) but this requires serious privileges and even it can be defeated.

Wait and Sleep functions lock Excel and you can't do anything else until the delay finishes. On the other hand Loop delays doesn't give you an exact time to wait.

So, I've made this workaround joining a little bit of both concepts. It loops until the time is the time you want.

Private Sub Waste10Sec()
   target = (Now + TimeValue("0:00:10"))
   Do
       DoEvents 'keeps excel running other stuff
   Loop Until Now >= target
End Sub

You just need to call Waste10Sec where you need the delay

If you are not bothered about the location of the text present, then you could use Driver.PageSource property as below:

Driver.PageSource.Contains("expected message");

As an improvement to both Praveen and Tony, I use an override:

public partial class MyDatabaseEntities : DbContext
{
    public override int SaveChanges()
    {
        try
        {
            return base.SaveChanges();
        }
        catch (DbEntityValidationException dbEx)
        {
            foreach (var validationErrors in dbEx.EntityValidationErrors)
            {
                foreach (var validationError in validationErrors.ValidationErrors)
                {
                    Trace.TraceInformation("Class: {0}, Property: {1}, Error: {2}",
                        validationErrors.Entry.Entity.GetType().FullName,
                        validationError.PropertyName,
                        validationError.ErrorMessage);
                }
            }

            throw;  // You can also choose to handle the exception here...
        }
    }
}

Try this listeners=PLAINTEXT://localhost:9092 It must be helpful

Many thanks

The default kill command accepts command names as an alternative to PID. See kill (1). An often occurring trouble is that bash provides its own kill which accepts job numbers, like kill %1, but not command names. This hinders the default command. If the former functionality is more useful to you than the latter, you can disable the bash version by calling

enable -n kill

For more info see kill and enable entries in bash (1).

@Casperah pointed out that i'm thinking about it wrong:

• A TextBox doesn't have lines
• it has text
• that text can be split on the CRLF into lines, if requested
• but there is no notion of lines

The question then is how to accomplish what i want, rather than what WinForms lets me.

There are subtle bugs in the other given variants:

• textBox1.AppendText("Hello" + Environment.NewLine);
• textBox1.AppendText("Hello" + "\r\n");
• textBox1.Text += "Hello\r\n"
• textbox1.Text += System.Environment.NewLine + "brown";

They either append or prepend a newline when one (might) not be required.

So, extension helper:

public static class WinFormsExtensions
{
   public static void AppendLine(this TextBox source, string value)
   {
      if (source.Text.Length==0)
         source.Text = value;
      else
         source.AppendText("\r\n"+value);
   }
}

So now:

textBox1.Clear();
textBox1.AppendLine("red");
textBox1.AppendLine("green");
textBox1.AppendLine("blue");

and

textBox1.AppendLine(String.Format("Processing file {0}", filename));

You should use LoadXml method, not Load:

xmlDoc.LoadXml(myXML); 

Load method is trying to load xml from a file and LoadXml from a string. You could also use XPath:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xml);

string xpath = "myDataz/listS/sog";
var nodes = xmlDoc.SelectNodes(xpath);

foreach (XmlNode childrenNode in nodes)
{
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("//field1").Value);
} 

The best superuser role would be the root.The Syntax is:

use admin

db.createUser(
{
    user: "root",
    pwd: "password",
    roles: [ "root" ]
})

For more details look at built-in roles.

Hope this helps !!!
