Using PHP i've found a quite simple way to do this. Guys, Just Use something like this

<input list="customers" name="customer_id" required class="form-control" placeholder="Customer Name">
            <datalist id="customers">
                <?php 
    $querySnamex = "SELECT * FROM `customer` WHERE fname!='' AND lname!='' order by customer_id ASC";
    $resultSnamex = mysqli_query($con,$querySnamex) or die(mysql_error());

                while ($row_this = mysqli_fetch_array($resultSnamex)) {
                    echo '<option data-value="'.$row_this['customer_id'].'">'.$row_this['fname'].' '.$row_this['lname'].'</option>
                    <input type="hidden" name="customer_id_real" value="'.$row_this['customer_id'].'" id="answerInput-hidden">';
                }

                 ?>
            </datalist>

The Code Above lets the form carry the id of the option also selected.

Can you try to change your json without data key like below?

[{"target_id":9503123,"target_type":"user"}]

Easy:

[v for k, v in df.groupby('name')]

I was trying to select an area of svg with a rectangle and get all the elements from it. For this, element.getBoundingClientRect() worked perfectly for me. It returns current coordinates of svg elements regardless of whether svg is scaled or transformed.

To get the last element, simply use the size of the list as the second parameter. So for example, if you have 35 files, and you want the last five, you would do:

dataList.subList(30, 35);

A guaranteed safe way to do this is:

dataList.subList(Math.max(0, first), Math.min(dataList.size(), last) );

Think of it as the difference between a requirement and a suggestion. For the select element, the user is required to select one of the options you've given. For the datalist element, it is suggested that the user select one of the options you've given, but he can actually enter anything he wants in the input.

Edit 1: So which one you use depends upon your requirements. If the user must enter one of your choices, use the select element. If the use can enter whatever, use the datalist element.

Edit 2: Found this tidbit in the HTML Living Standard: "Each option element that is a descendant of the datalist element...represents a suggestion."

Jeffrey L Whitledge is right. Your `dataList´-Object itself is null.

There is also another problem with your code: You are using the ref-keyword, which means the argument data cannot be null! The MSDN says:

An argument passed to a ref parameter must first be initialized. This differs from out, whose arguments do not have to be explicitly initialized before they are passed

It's also not a good idea to use generics with the type `Object´. Generics should avoid boxing/unboxing and also ensure type safety. If you want a common type make your method generic. Finally your code should look like this:

public class Foo<T> where T : MyTypeOrInterface {

      public List<T> dataList = new List<T>();

      public bool AddData(ref T data) {
        bool success = false;
        try {
          dataList.Add(data);                   
          success = doOtherStuff(data);
        } catch (Exception e) {
          throw new Exception(e.ToString());
        }
        return success;
      }

      private bool doOtherStuff(T data) {
        //...
      }
    }

DECLARE @TABLE TABLE 
  (RowNo INT,ScripName  VARCHAR(10),ScripCode  VARCHAR(10)
  ,Price  VARCHAR(10))      
INSERT INTO @TABLE VALUES
  (1,'20 MICRONS ','533022','39')
SELECT ColumnName,ColumnValue from @Table
 Unpivot(ColumnValue For ColumnName IN (ScripName,ScripCode,Price)) AS H

System.out.println("Element "+i+list.get(0));}

Should be

System.out.println("Element "+i+list.get(i));}

To use the JSF tags, you give the dataList value attribute a reference to your list of elements, and the var attribute is a local name for each element of that list in turn. Inside the dataList, you use properties of the object (getters) to output the information about that individual object:

<t:dataList id="myDataList" value="#{houseControlList}" var="element" rows="3" >
...
<t:outputText id="houseId" value="#{element.houseId}"/>
...
</t:dataList>

There are a few ways to handle rendering/showing controls on the page and you should take note to what happens with each method.

Rendering and Visibility

There are some instances where elements on your page don't need to be rendered for the user because of some type of logic or database value. In this case, you can prevent rendering (creating the control on the returned web page) altogether. You would want to do this if the control doesn't need to be shown later on the client side because no matter what, the user viewing the page never needs to see it.

Any controls or elements can have their visibility set from the server side. If it is a plain old html element, you just need to set the runat attribute value to server on the markup page.

<div id="myDiv" runat="server"></div>

The decision to render the div or not can now be done in the code behind class like so:

myDiv.Visible = someConditionalBool;

If set to true, it will be rendered on the page and if it's false it won't be rendered at all, not even hidden.

Client Side Hiding

Hiding an element is done on the client side only. Meaning, it's rendered but it has a display CSS style set on it which instructs your browser to not show it to the user. This is beneficial when you want to hide/show things based on user input. It's important to know that the element CAN be hidden on the server side too as long as the element/control has runat=server set just as I explained in the previous example.

Hiding in the Code Behind Class

To hide an element that you want rendered to the page but hidden is another simple single line of code:

myDiv.Style["display"] = "none";

If you have a need to remove the display style server side, it can be done by removing the display style, or setting it to a different value like inline or block (values described here).

myDiv.Style.Remove("display");
// -- or --
myDiv.Style["display"] = "inline";

Hiding on the Client Side with javascript

Using plain old javascript, you can easily hide the same element in this manner

var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";

// then to show again
myDivElem.style.display = "";

jQuery makes hiding elements a little simpler if you prefer to use jQuery:

var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();

// ... and to show 
myDiv.show();

I've tried all above and [readr][1] made the best job. I have only 8gb RAM

Loop for 20 files, 5gb each, 7 columns:

read_fwf(arquivos[i],col_types = "ccccccc",fwf_cols(cnpj = c(4,17), nome = c(19,168), cpf = c(169,183), fantasia = c(169,223), sit.cadastral = c(224,225), dt.sitcadastral = c(226,233), cnae = c(376,382)))

For the benefit of searchers; if you are using jQuery, you can do the following:

var currentOverride = $('#customoverridestyles');

if (currentOverride) {
 currentOverride.remove();
}

$('body').append("<style id=\"customoverridestyles\">body{background-color:pink;}</style>");

Obviously you can change the inner css to whatever you want.

Appreciate some people prefer pure JavaScript, but it works and has been pretty robust for writing/overwriting styles dynamically.

Make sure you declare the bean associated with the form in GET method of the associated controller and also add it in the model model.addAttribute("uploadItem", uploadItem); which contains @RequestMapping(method = RequestMethod.GET) annotation.

For example UploadItem.java is associated with myform.jsp and controller is SecureAreaController.java

myform.jsp contains

<form:form action="/securedArea" commandName="uploadItem" enctype="multipart/form-data"></form:form>

MyFormController.java

@RequestMapping("/securedArea")
@Controller
public class SecureAreaController {

@RequestMapping(method = RequestMethod.GET)
public String showForm(Model model) {
            UploadItem uploadItem = new UploadItem(); // declareing

            model.addAttribute("uploadItem", uploadItem); // adding in model
    return "securedArea/upload";
}

}

As you can see I am declaring UploadItem.java in controller GET method.

I found that you can make use of the white-space CSS property:

white-space: normal;

And it will break the words as normal text.

What about ordering desc by the desired property,

   blah = blah.OrderByDescending(x => x.Property);

And then doing something like

  if (!descending)
  {
       blah = blah.Reverse()
  }
  else
  {
      // Already sorted desc ;)
  }

Is it Reverse() too slow?

With .NET 4.0 I find System.Threading.Tasks a lot easier to work with. Here's spin-wait loop which works reliably for me. It blocks the main thread until all the tasks complete. There's also Task.WaitAll, but that hasn't always worked for me.

        for (int i = 0; i < N; i++)
        {
            tasks[i] = Task.Factory.StartNew(() =>
            {               
                 DoThreadStuff(localData);
            });
        }
        while (tasks.Any(t => !t.IsCompleted)) { } //spin wait

The other option to try is a straightforward

<img width="100" height="100" src="/root/Image/image.jpeg" class="CalloutRightPhoto"/>

i.e. without {} but instead giving the direct image path

add like

<head runat="server">
<script src="Registration.js" type="text/javascript"></script>
</head>

OR can add in code behind.

Page.ClientScript.RegisterClientScriptInclude("Registration", ResolveUrl("~/js/Registration.js"));

I had this issue too, also running on an emulator.. The same message was showing up on Logcat, but it wasn't affecting the functionality of the app. But it was annoying, and I don't like seeing errors on the log that I don't understand.

Anyway, I got rid of the message by increasing the RAM on the emulator.

In a functional component this principle also works, it's just a slightly different syntax and way of thinking.

const UploadsWindow = () => {
  // will hold a reference for our real input file
  let inputFile = '';

  // function to trigger our input file click
  const uploadClick = e => {
    e.preventDefault();
    inputFile.click();
    return false;
  };

  return (
    <>
      <input
        type="file"
        name="fileUpload"
        ref={input => {
          // assigns a reference so we can trigger it later
          inputFile = input;
        }}
        multiple
      />

      <a href="#" className="btn" onClick={uploadClick}>
        Add or Drag Attachments Here
      </a>
    </>
  )

}

With pure html (no JS), you can't really substitute a radio-button for an image (at least, I don't think you can). You could, though use the following to make the same connection to the user:

<form action="" method="post">
    <fieldset>
       <input type="radio" name="feeling" id="feelingSad" value="sad" /><label for="feelingSad"><img src="path/to/sad.png" /></label>
       <label for="feelingHappy"><input type="radio" name="feeling" id="feelingHappy" value="happy" /><img src="path/to/happy.png" /></label>
    </fieldset>
</form>

public boolean deleteRow(long l) {
    String where = "ID" + "=" + l;
    return db.delete(TABLE_COUNTRY, where, null) != 0;
}

Try this:

$query = mysql_query("SELECT username FROM Users WHERE username='$username' ")

Don't add $con to mysql_query() function.

Disclaimer: using the username variable in the string passed to mysql_query, as shown above, is a trivial SQL injection attack vector in so far the username depends on parameters of the Web request (query string, headers, request body, etc), or otherwise parameters a malicious entity may control.

Bash 4 has a coproc command which establishes a named pipe to a command and allows you to communicate through it.

business = Business.where(:user_id => current_user.id).first
if business.nil?
# no business found
else
# business.ceo = "me"
end

A good thing to remember are these simple rules, and they apply to both parameters and return types...

• Value - makes a copy of the item in question.
• Pointer - refers to the address of the item in question.
• Reference - is literally the item in question.

There is a time and place for each, so make sure you get to know them. Local variables, as you've shown here, are just that, limited to the time they are locally alive in the function scope. In your example having a return type of int* and returning &i would have been equally incorrect. You would be better off in that case doing this...

void func1(int& oValue)
{
    oValue = 1;
}

Doing so would directly change the value of your passed in parameter. Whereas this code...

void func1(int oValue)
{
    oValue = 1;
}

would not. It would just change the value of oValue local to the function call. The reason for this is because you'd actually be changing just a "local" copy of oValue, and not oValue itself.

Don't forget the padding and margins...

jQuery.fn.slideLeftHide = function(speed, callback) { 
  this.animate({ 
    width: "hide", 
    paddingLeft: "hide", 
    paddingRight: "hide", 
    marginLeft: "hide", 
    marginRight: "hide" 
  }, speed, callback);
}

jQuery.fn.slideLeftShow = function(speed, callback) { 
  this.animate({ 
    width: "show", 
    paddingLeft: "show", 
    paddingRight: "show", 
    marginLeft: "show", 
    marginRight: "show" 
  }, speed, callback);
}

With the speed/callback arguments added, it's a complete drop-in replacement for slideUp() and slideDown().

You could do the following for ES5:

var theTop = 'top'
<something>.stop().animate(
  JSON.parse('{"' + theTop + '":' + JSON.stringify(10) + '}'), 10
)

Or extract to a function:

function newObj (key, value) {
  return JSON.parse('{"' + key + '":' + JSON.stringify(value) + '}')
}

var theTop = 'top'
<something>.stop().animate(
  newObj(theTop, 10), 10
)

I traced the Apache code through DigestUtils and sha256 seems to default back to java.security.MessageDigest for calculation. Apache does not implement an independent sha256 solution. I was looking for an independent implementation to compare against the java.security library. FYI only.

You can do it like that 2>&1:

 command > file 2>&1

It points to your top level output directory (which by default is target):

https://web.archive.org/web/20150527103929/http://docs.codehaus.org/display/MAVENUSER/MavenPropertiesGuide

EDIT: As has been pointed out, Codehaus is now sadly defunct. You can find details about these properties from Sonatype here:

http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-properties.html#resource-filtering-sect-project-properties

If you are ever trying to reference output directories in Maven, you should never use a literal value like target/classes. Instead you should use property references to refer to these directories.

    project.build.sourceDirectory
    project.build.scriptSourceDirectory
    project.build.testSourceDirectory
    project.build.outputDirectory
    project.build.testOutputDirectory
    project.build.directory

sourceDirectory, scriptSourceDirectory, and testSourceDirectory provide access to the source directories for the project. outputDirectory and testOutputDirectory provide access to the directories where Maven is going to put bytecode or other build output. directory refers to the directory which contains all of these output directories.

In sake of readability it should be something like

<?php 
  $countries = $myaddress->get_countries();
  foreach($countries as $value) {
    $selected ='';
    if($value=='United States') $selected ='selected="selected"'; 
    echo '<option value="'.$value.'"'.$selected.'>'.$value.'</option>';
  }
?>

desire to stuff EVERYTHING in a single line is a decease, man. Write distinctly.

But there is another way, a better one. There is no need to use echo at all. Learn to use templates. Prepare your data first, and display it only then ready.

Business logic part:

$countries = $myaddress->get_countries();
$selected_country = 1;    

Template part:

<? foreach($countries as $row): ?>
<option value="<?=$row['id']?>"<? if ($row['id']==$current_country):> "selected"><? endif ?>
  <?=$row['name']?>
</option>
<? endforeach ?>

I stumbled across this article looking for a similar answer. I read @vsync example Using javascript's Number.prototype.toLocaleString: and it appeared to work well. The only complaint I had was that if you had more than a single input type="currency" within your page it would only modify the first instance of it.

As he mentions in his comments it was only designed as an example for stackoverflow.

However, the example worked well for me and although I have little experience with JS I figured out how to modify it so that it will work with multiple input type="currency" on the page using the document.querySelectorAll rather than document.querySelector and adding a for loop.

I hope this can be useful for someone else. ( Credit for the bulk of the code is @vsync )

var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

for ( var i = 0; i < currencyInput.length; i++ ) {

    var currency = 'GBP'
    onBlur( {
        target: currencyInput[ i ]
    } )

    currencyInput[ i ].addEventListener( 'focus', onFocus )
    currencyInput[ i ].addEventListener( 'blur', onBlur )

    function localStringToNumber( s ) {
        return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
    }

    function onFocus( e ) {
        var value = e.target.value;
        e.target.value = value ? localStringToNumber( value ) : ''
    }

    function onBlur( e ) {
        var value = e.target.value

        var options = {
            maximumFractionDigits: 2,
            currency: currency,
            style: "currency",
            currencyDisplay: "symbol"
        }

        e.target.value = ( value || value === 0 ) ?
            localStringToNumber( value ).toLocaleString( undefined, options ) :
            ''
    }
}

    var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

    for ( var i = 0; i < currencyInput.length; i++ ) {

        var currency = 'GBP'
        onBlur( {
            target: currencyInput[ i ]
        } )

        currencyInput[ i ].addEventListener( 'focus', onFocus )
        currencyInput[ i ].addEventListener( 'blur', onBlur )

        function localStringToNumber( s ) {
            return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
        }

        function onFocus( e ) {
            var value = e.target.value;
            e.target.value = value ? localStringToNumber( value ) : ''
        }

        function onBlur( e ) {
            var value = e.target.value

            var options = {
                maximumFractionDigits: 2,
                currency: currency,

                currencyDisplay: "symbol"
            }

            e.target.value = ( value || value === 0 ) ?

CREATE TEMPORARY TABLE IF NOT EXISTS table2 AS (SELECT * FROM table1)

From the manual found at http://dev.mysql.com/doc/refman/5.7/en/create-table.html

You can use the TEMPORARY keyword when creating a table. A TEMPORARY table is visible only to the current session, and is dropped automatically when the session is closed. This means that two different sessions can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name. (The existing table is hidden until the temporary table is dropped.) To create temporary tables, you must have the CREATE TEMPORARY TABLES privilege.

If you want to print decimal variables:

wchar_t text_buffer[20] = { 0 }; //temporary buffer
swprintf(text_buffer, _countof(text_buffer), L"%d", your.variable); // convert
OutputDebugString(text_buffer); // print

I just coded an extension for python-markdown, which uses its parser to retrieve headings, and outputs a TOC as Markdown-formatted unordered list with local links. The file is

• md_toc.py (was md_toc.py)

... and it should be placed in markdown/extensions/ directory in the markdown installation. Then, all you have to do, is type anchor <a> tags with an id="..." attribute as a reference - so for an input text like this:

$ cat test.md 
Hello
=====

## <a id="sect one"></a>SECTION ONE ##

something here

### <a id='sect two'>eh</a>SECTION TWO ###

something else

#### SECTION THREE

nothing here

### <a id="four"></a>SECTION FOUR

also...

... the extension can be called like this:

$ python -m markdown -x md_toc test.md 
* Hello
    * [SECTION ONE](#sect one)
        * [SECTION TWO](#sect two)
            * SECTION THREE
        * [SECTION FOUR](#four)

... and then you can paste back this toc in your markdown document (or have a shortcut in your text editor, that calls the script on the currently open document, and then inserts the resulting TOC in the same document).

Note that older versions of python-markdown don't have a __main__.py module, and as such, the command line call as above will not work for those versions.

str.isalpha()

Return true if all characters in the string are alphabetic and there is at least one character, false otherwise. Alphabetic characters are those characters defined in the Unicode character database as “Letter”, i.e., those with general category property being one of “Lm”, “Lt”, “Lu”, “Ll”, or “Lo”. Note that this is different from the “Alphabetic” property defined in the Unicode Standard.

In python2.x:

>>> s = u'a1??'
>>> for char in s: print char, char.isalpha()
...
a True
1 False
? True
? True
>>> s = 'a1??'
>>> for char in s: print char, char.isalpha()
...
a True
1 False
? False
? False
? False
? False
? False
? False
>>>

In python3.x:

>>> s = 'a1??'
>>> for char in s: print(char, char.isalpha())
...
a True
1 False
? True
? True
>>>

This code work:

>>> def is_alpha(word):
...     try:
...         return word.encode('ascii').isalpha()
...     except:
...         return False
...
>>> is_alpha('??')
False
>>> is_alpha(u'??')
False
>>>

>>> a = 'a'
>>> b = 'a'
>>> ord(a), ord(b)
(65345, 97)
>>> a.isalpha(), b.isalpha()
(True, True)
>>> is_alpha(a), is_alpha(b)
(False, True)
>>>

The easiest way would be to use: SELECT DATE(GETDATE())

Well, you just fire the desired click event:

$(".first").click(function(){
    $(".second").click(); 
    return false;
});

If you have access to ES2015 functions, and you're looking for a more functional approach I'd go with something like:

const people = [
  { id: 1, name: 'serdar' },
  { id: 5, name: 'alex' },
  { id: 300, name: 'brittany' }
];

const idToRemove = 5;

const filteredPeople = people.filter((item) => item.id !== idToRemove);

// [
//   { id: 1, name: 'serdar' },
//   { id: 300, name: 'brittany' }
// [

Watch out though, filter() is non-mutating, so you'll get a new array back.

See the Mozilla Developer Network notes on Filter.

Perhaps am late or maybe you've already used it before but there is another one called ksoap and its pretty amazing.. It also includes timeouts and can parse any SOAP based webservice efficiently. I also made a few changes to suit my parsing.. Look it up

How about this?

CASE WHEN ProductAlternateKey is NOT NULL THEN
CONVERT(NVARCHAR(25), LTRIM(RTRIM(ProductAlternateKey))) 
FROM DimProducts
where ProductAlternateKey  like '46783815%'

Why has nobody used the foreach loop yet? A pro here is that you can easily name your variable:

# Note that I'm pretty explicit here. This would work as well as the line after:
# Get-ChildItem -Recurse C:\windows\System32\*.txt
$fileList = Get-ChildItem -Recurse -Path C:\windows\System32 -Include *.txt
foreach ($textfile in $fileList) {
    # This includes the filename ;)
    $filePath = $textfile.fullname
    # You can replace the next line with whatever you want to.
    Write-Output $filePath
}

I Don't know what do you mean exactly, but technially speaking, this is not possible without a loop.

May be you mean using a LINQ, like for example:

list.Where(x=>x.Title == title)

It's worth mentioning that the iteration over is not skipped, but simply wrapped into the LINQ query.

Hope this helps.

EDIT

In other words if you really concerned about performance, keep coding the way you already doing. Otherwise choose LINQ for more concise and clear syntax.

It seems there are pros and cons to using either ?? or ?:. The pro to using ?: is that it evaluates false and null and "" the same. The con is that it reports an E_NOTICE if the preceding argument is null. With ?? the pro is that there is no E_NOTICE, but the con is that it does not evaluate false and null the same. In my experience, I have seen people begin using null and false interchangeably but then they eventually resort to modifying their code to be consistent with using either null or false, but not both. An alternative is to create a more elaborate ternary condition: (isset($something) or !$something) ? $something : $something_else.

The following is an example of the difference of using the ?? operator using both null and false:

$false = null;
$var = $false ?? "true";
echo $var . "---<br>";//returns: true---

$false = false;
$var = $false ?? "true";
echo $var . "---<br>"; //returns: ---

By elaborating on the ternary operator however, we can make a false or empty string "" behave as if it were a null without throwing an e_notice:

$false = null;
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: ---

$false = false;
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: ---

$false = "";
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: ---

$false = true;
$var = (isset($false) or !$false) ? $false : "true";
echo $var . "---<br>";//returns: 1---

Personally, I think it would be really nice if a future rev of PHP included another new operator: :? that replaced the above syntax. ie: // $var = $false :? "true"; That syntax would evaluate null, false, and "" equally and not throw an E_NOTICE...

This will re-size any image using the best quality with support for 32bpp with alpha. The new image will have the original image centered inside the new one at the original aspect ratio.

This is pattern to enter the date for textbox in HTML5.
The first one[0-9]{1,2} will take only decimal number minimum 1 and maximum 2.
And other similarly.

For what it's worth I had this issue and had to go into cPanel where I saw the error message

"Attention! Please register your email IDs used in non-smtp mails through cpanel plugin. Unregistered email IDs will not be allowed in non-smtp emails sent through scripts. Go to Mail section and find "Registered Mail IDs" plugin in paper_lantern theme."

Registering the emails in cPanel (Register Mail IDs) and waiting 10 mins got mine to work.

Hope that helps someone.

Use the LayoutInflater to create a view based on your layout template, and then inject it into the view where you need it.

LayoutInflater vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = vi.inflate(R.layout.your_layout, null);

// fill in any details dynamically here
TextView textView = (TextView) v.findViewById(R.id.a_text_view);
textView.setText("your text");

// insert into main view
ViewGroup insertPoint = (ViewGroup) findViewById(R.id.insert_point);
insertPoint.addView(v, 0, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

You may have to adjust the index where you want to insert the view.

Additionally, set the LayoutParams according to how you would like it to fit in the parent view. e.g. with FILL_PARENT, or MATCH_PARENT, etc.

Set content type. Look at this method.

message.setContent("<h1>Hello</h1>", "text/html");

Copy-pasted from here: Incrementing a date in JavaScript

Three options for you:

Using just JavaScript's Date object (no libraries):

var today = new Date();
var tomorrow = new Date(today.getTime() + (24 * 60 * 60 * 1000));

Or if you don't mind changing the date in place (rather than creating a new date):

var dt = new Date();
dt.setTime(dt.getTime() + (24 * 60 * 60 * 1000));

Edit: See also Jigar's answer and David's comment below: var tomorrow = new Date(); tomorrow.setDate(tomorrow.getDate() + 1);

Using MomentJS:

var today = moment();
var tomorrow = moment(today).add(1, 'days');

(Beware that add modifies the instance you call it on, rather than returning a new instance, so today.add(1, 'days') would modify today. That's why we start with a cloning op on var tomorrow = ....)

Using DateJS, but it hasn't been updated in a long time:

var today = new Date(); // Or Date.today()
var tomorrow = today.add(1).day();

There are already great answers about the advantages of using list initialization, however my personal rule of thumb is NOT to use curly braces whenever possible, but instead make it dependent on the conceptual meaning:

• If the object I'm creating conceptually holds the values I'm passing in the constructor (e.g. containers, POD structs, atomics, smart pointers etc.), then I'm using the braces.
• If the constructor resembles a normal function call (it performs some more or less complex operations that are parametrized by the arguments) then I'm using the normal function call syntax.
• For default initialization I always use curly braces.
  For one, that way I'm always sure that the object gets initialized irrespective of whether it e.g. is a "real" class with a default constructor that would get called anyway or a builtin / POD type. Second it is - in most cases - consistent with the first rule, as a default initialized object often represents an "empty" object.

In my experience, this ruleset can be applied much more consistently than using curly braces by default, but having to explicitly remember all the exceptions when they can't be used or have a different meaning than the "normal" function-call syntax with parenthesis (calls a different overload).

It e.g. fits nicely with standard library-types like std::vector:

vector<int> a{10,20};   //Curly braces -> fills the vector with the arguments

vector<int> b(10,20);   //Parentheses -> uses arguments to parametrize some functionality,                          
vector<int> c(it1,it2); //like filling the vector with 10 integers or copying a range.

vector<int> d{};      //empty braces -> default constructs vector, which is equivalent
                      //to a vector that is filled with zero elements

The problem is not in your code but in your json:

{"Compemployes":[{"id":1001,"name":"jhon"}, {"id":1002,"name":"jhon"}]}

this represents an object which contains a property Compemployes which is a list of Employee. In that case you should create that object like:

class EmployeList{
    private List<Employe> compemployes;
    (with getter an setter)
}

and to deserialize the json simply do:

EmployeList employeList = mapper.readValue(jsonString,EmployeList.class);

If your json should directly represent a list of employees it should look like:

[{"id":1001,"name":"jhon"}, {"id":1002,"name":"jhon"}]

Last remark:

List<Employee> list2 = mapper.readValue(jsonString, 
TypeFactory.collectionType(List.class, Employee.class));

TypeFactory.collectionType is deprecated you should now use something like:

List<Employee> list = mapper.readValue(jsonString,
TypeFactory.defaultInstance().constructCollectionType(List.class,  
   Employee.class));

I have implemented a custom controller that dynamically calculates the size of the keyboard, scrolling textFields when it appears and disappears, even during rotation of the device. Works with all iOS devices. Just simply inherit the controller to have what you need. You can find it with all the instructions at the following link: https://github.com/mikthebig/ios-textfield-scroll

A better solution than selected answer would be to use border-size rather than border-spacing. The main problem with using border-spacing is that even the first column would have a spacing in the front.

For example,

table {_x000D_
  border-collapse: separate;_x000D_
  border-spacing: 80px 0;_x000D_
}_x000D_
_x000D_
td {_x000D_
  padding: 10px 0;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>First Column</td>_x000D_
    <td>Second Column</td>_x000D_
    <td>Third Column</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>1</td>_x000D_
    <td>2</td>_x000D_
    <td>3</td>_x000D_
  </tr>_x000D_
</table>

To avoid this use: border-left: 100px solid #FFF; and set border:0px for the first column.

For example,

td,th{_x000D_
  border-left: 100px solid #FFF;_x000D_
}_x000D_
_x000D_
 tr>td:first-child {_x000D_
   border:0px;_x000D_
 }

<table id="t">_x000D_
  <tr>_x000D_
    <td>Column1</td>_x000D_
    <td>Column2</td>_x000D_
    <td>Column3</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>1000</td>_x000D_
    <td>2000</td>_x000D_
    <td>3000</td>_x000D_
  </tr>_x000D_
</table>

Just because you're in PowerShell don't forgot about good ol' exes. Sometimes they can provide the easiest solution e.g.:

icacls.exe $folder /grant 'domain\user:(OI)(CI)(M)'

I am answering the title of the question rather than the original question which was more specific.

With the new features of Javascript like iterators and generator functions and objects, something like LINQ for Javascript becomes possible. Note that linq.js, for example, uses a completely different approach, using regular expressions, probably to overcome the lack of support in the language at the time.

With that being said, I've written a LINQ library for Javascript and you can find it at https://github.com/Siderite/LInQer. Comments and discussion at https://siderite.dev/blog/linq-in-javascript-linqer.

From previous answers, only Manipula seems to be what one would expect from a LINQ port in Javascript.

A while ago I was in a similar situation (allthough I had a little WPF knowledge already), so I started a community wiki. There are a lot of great ressources there:

What applications could I study to understand (Data)Model-View-ViewModel?

I had the same issue in 14.04, but I fixed it by these steps:

1. sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
2. echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb- org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
3. sudo apt-get update
4. sudo apt-get install -y mongodb

It worked like charm :)

If you want to modify the original array instead of returning a new array, use .push()...

array1.push.apply(array1, array2);
array1.push.apply(array1, array3);

I used .apply to push the individual members of arrays 2 and 3 at once.

or...

array1.push.apply(array1, array2.concat(array3));

To deal with large arrays, you can do this in batches.

for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
    array1.push.apply(array1, to_add.slice(n, n+300));
}

If you do this a lot, create a method or function to handle it.

var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);

Object.defineProperty(Array.prototype, "pushArrayMembers", {
    value: function() {
        for (var i = 0; i < arguments.length; i++) {
            var to_add = arguments[i];
            for (var n = 0; n < to_add.length; n+=300) {
                push_apply(this, slice_call(to_add, n, n+300));
            }
        }
    }
});

and use it like this:

array1.pushArrayMembers(array2, array3);

var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
    value: function() {_x000D_
        for (var i = 0; i < arguments.length; i++) {_x000D_
            var to_add = arguments[i];_x000D_
            for (var n = 0; n < to_add.length; n+=300) {_x000D_
                push_apply(this, slice_call(to_add, n, n+300));_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);

You can use WordPress predefined function to add script file to WordPress plugin.

wp_enqueue_script( 'script', plugins_url('js/demo_script.js', __FILE__), array('jquery'));

Look at the post which helps you to understand that how easily you can implement jQuery and CSS in WordPress plugin.

I use this code ...

 function rmDirectory($dir) {
        foreach(glob($dir . '/*') as $file) {
            if(is_dir($file))
                rrmdir($file);
            else
                unlink($file);
        }
        rmdir($dir);
    }

or this one...

<?php 
public static function delTree($dir) { 
   $files = array_diff(scandir($dir), array('.','..')); 
    foreach ($files as $file) { 
      (is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file"); 
    } 
    return rmdir($dir); 
  } 
?>

Just another information... Had that problem today on a Windows 2012 R2 x64 TS system where the application was started from a unc/network path. The issue occured for one application for all terminal server users. Executing the application locally worked without problems. After a reboot it started working again - the SEHException's thrown had been Constructor init and TargetInvocationException

With Ajax, for me worked:

Html:

<div id='anID'>
 <form name="nameOfForm">
            <p><b>Your headline</b></p>
            <input type='radio' name='nameOfRadio' value='seed' 
             <?php if ($interviewStage == 'seed') {echo" checked ";}?> 
            onchange='funcInterviewStage()'><label>Your label</label><br>
 </form>
</div>

Javascript:

 function funcInterviewStage() {

                var dis = document.nameOfForm.nameOfRadio.value;

                //Auswahltafel anzeigen
                  if (dis == "") {
                      document.getElementById("anID").innerHTML = "";
                      return;
                  } else { 
                      if (window.XMLHttpRequest) {
                          // code for IE7+, Firefox, Chrome, Opera, Safari
                          xmlhttp = new XMLHttpRequest();
                      } else {
                          // code for IE6, IE5
                          xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
                      }
                      xmlhttp.onreadystatechange = function() {
                          if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                              document.getElementById("anID").innerHTML = xmlhttp.responseText;
                          }
                      }
                      xmlhttp.open("GET","/includes/[name].php?id="+dis,true);
                      xmlhttp.send();
                  }
              }  

And php:

//// Get Value
$id = mysqli_real_escape_string($db, $_GET['id']);

//// Insert to database
$insert = mysqli_query($db, "UPDATE [TABLE] SET [column] = '$id' WHERE [...]");

//// Show radio buttons again
$mysqliAbfrage = mysqli_query($db, "SELECT [column] FROM [Table] WHERE [...]");
                  while ($row = mysqli_fetch_object($mysqliAbfrage)) {
                    ...
                  }
                  echo" 
                  <form name='nameOfForm'>
                      <p><b>Your headline</b></p>
                      <input type='radio' name='nameOfRadio' value='seed'"; if ($interviewStage == 'seed') {echo" checked ";} echo" onchange='funcInterviewStage()'><label>Yourr Label</label><br>
                      <input type='radio' name='nameOfRadio' value='startup'"; if ($interviewStage == 'startup') {echo" checked ";} echo" onchange='funcInterviewStage()'><label>Your label</label><br>

                  </form> ";

Besides Manuel's way, you can still use the Manifest.

In Android Studio stable, you have to add the following 2 lines to application in the AndroidManifest file:

    android:debuggable="true"
    tools:ignore="HardcodedDebugMode"

The first one will enable debugging of signed APK, and the second one will prevent compile-time error.

After this, you can attach to the process via "Attach debugger to Android process" button.

there is a better way.

View.performClick();

http://developer.android.com/reference/android/view/View.html#performClick()

this should answer all your problems. every View inherits this function, including Button, Spinner, etc.

Just to clarify, View does not have a static performClick() method. You must call performClick() on an instance of View. For example, you can't just call

View.performClick();

Instead, do something like:

View myView = findViewById(R.id.myview);
myView.performClick();

jQuery 3.0 removed .error. Correct syntax is now

$(this).on('error', function(){
    console.log('Image does not exist: ' + this.id); 
});

copy a file from a local server to a remote server

sudo scp -i my-pem-file.pem ./source/test.txt [email protected]:~/destination/

copy a file from a remote server to a local machine

sudo scp -i my-pem-file.pem [email protected]:~/source/of/remote/test.txt ./where/to/put

So the basically syntax is:-

scp -i my-pem-file.pem username@source:/location/to/file username@destination:/where/to/put

-i is for the identity_file

This is the problem that is occurring,

if the JAR file was loaded from "C:\java\apps\appli.jar", and your manifest file has the Class-Path: reference "lib/other.jar", the class loader will look in "C:\java\apps\lib\" for "other.jar". It won't look at the JAR file entry "lib/other.jar".

Solution:-

1. Right click on project, Select Export.
2. Select Java Folder and in it select Runnable JAR File instead of JAR file.
3. Select the proper options and in the Library Handling section select the 3rd option i.e. (Copy required libraries into a sub-folder next to the generated JAR).

[ EDIT = 3rd option generates a folder in addition to the jar, 2nd option ("Package required libraries into generated JAR") can also be used as you have the jar. ]

4. Click finish and your JAR is created at the specified position along with a folder that contains the JARS mentioned in the manifest file.

5. open the terminal,give the proper path to your jar and run it using this command java -jar abc.jar

   Now what will happen is the class loader will look in the correct folder for the referenced JARS since now they are present in the same folder that contains your app JAR..There is no "java.lang.NoClassDefFoundError" exception thrown now.

This worked for me... Hope it works for you too!!!

To add rows to existing DataTable in Dataset:

DataRow drPartMtl = DSPartMtl.Tables[0].NewRow();
drPartMtl["Group"] = "Group";
drPartMtl["BOMPart"] = "BOMPart";
DSPartMtl.Tables[0].Rows.Add(drPartMtl);

The directive can access any attribute that is defined on the same element, even if the directive itself is not the element.

Template:

<div example-directive example-number="99" example-function="exampleCallback()"></div>

Directive:

app.directive('exampleDirective ', function () {
    return {
        restrict: 'A',   // 'A' is the default, so you could remove this line
        scope: {
            callback : '&exampleFunction',
        },
        link: function (scope, element, attrs) {
            var num = scope.$eval(attrs.exampleNumber);
            console.log('number=',num);
            scope.callback();  // calls exampleCallback()
        }
    };
});

fiddle

If the value of attribute example-number will be hard-coded, I suggest using $eval once, and storing the value. Variable num will have the correct type (a number).

The proposed combination of os.listdir and sorted commands generates the same result as ls -l command under Linux. The following example verifies this assumption:

user@user-PC:/tmp/test$ touch 3a 4a 5a b c d1 d2 d3 k l p0 p1 p3 q 410a 409a 408a 407a
user@user-PC:/tmp/test$ ls -l

So, for someone who wants to reproduce the result of the well-known ls -l command in their python code, sorted( os.listdir( DIR ) ) works pretty well.

If you really want constants, not just variables looking like constants, the standard way to do it is to use immutable dictionaries. Unfortunately it's not built-in yet, so you have to use third party recipes (like this one or that one).

The parseInt function converts strings to numbers, and it takes a second argument specifying the base in which the string representation is:

var digit = parseInt(binary, 2);

See it in action.

I cannot comment Palehorse's answer so I added my own answer. Palehorse's logic is ok but efficiency can be bad with big data sets.

DELETE FROM some_child_table sct 
 WHERE exists (SELECT FROM some_Table st 
                WHERE sct.some_fk_fiel=st.some_id);

DELETE FROM some_table;

It is faster if you have indexes on columns and data set is bigger than few records.

In system/core/Common.php there is an exception handler, with a block of code that looks like this:

 // We don't bother with "strict" notices since they tend to fill up
 // the log file with excess information that isn't normally very helpful.
if ($severity == E_STRICT)
{
    return;
}

By removing the if and the return and the incorrect comment, I was able to get an error message, instead of just a blank page. This project isn't using the most recent version of CodeIgniter, hopefully they've fixed this bug by now.

System.Diagnostics.Process.Start("PATH to exe", "Command Line Arguments");

There is the semicolon missing (;) after the "50%"

but you should also notice that the percentage of your div is connected to the div that contains it.

for instance:

<div id="wrapper">
  <div class="container">
   adsf
  </div>
</div>

#wrapper {
  height:100px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

here the height of your .container will be 50px. it will be 50% of the 100px from the wrapper div.

if you have:

adsf

#wrapper {
  height:400px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

then you .container will be 200px. 50% of the wrapper.

So you may want to look at the divs "wrapping" your ".container"...

Short answers:

Q1: Yes.

Q2: Doesn't matter which you use.

Long answer:

A select ... for update will (as it implies) select certain rows but also lock them as if they have already been updated by the current transaction (or as if the identity update had been performed). This allows you to update them again in the current transaction and then commit, without another transaction being able to modify these rows in any way.

Another way of looking at it, it is as if the following two statements are executed atomically:

select * from my_table where my_condition;

update my_table set my_column = my_column where my_condition;

Since the rows affected by my_condition are locked, no other transaction can modify them in any way, and hence, transaction isolation level makes no difference here.

Note also that transaction isolation level is independent of locking: setting a different isolation level doesn't allow you to get around locking and update rows in a different transaction that are locked by your transaction.

What transaction isolation levels do guarantee (at different levels) is the consistency of data while transactions are in progress.

For me

DriverManager.registerDriver(new org.apache.derby.jdbc.EmbeddedDriver());

helped. In this way, the DriveManager does know the derby EmbeddedDriver. Maybe allocating a new EmbeddedDriver is to heavy but on the other side, Class.forName needs try/catch/doSomethingIntelligentWithException that I dont like very much.

I think the best way is to use currentTarget property instead of target property.

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred.

For example:

<a href="#"><span class="icon"></span> blah blah</a>

Javascript:

a.addEventListener('click', e => {
    e.currentTarget; // always returns "a" element
    e.target; // may return "a" or "span"
})

I know it is an old question. But I hope my answer will help somebody. I had the same issue and I think the problem is that it cannot find those .jar files in your local repository. So what I did is I added the following code to my pom.xml and it worked.

<repositories>
  <repository>
      <id>spring-milestones</id>
      <name>Spring Milestones</name>
      <url>https://repo.spring.io/libs-milestone</url>
      <snapshots>
          <enabled>false</enabled>
      </snapshots>
  </repository>
</repositories>

I know this is an old question, however here is a simple one-liner to switch it on or off depending on its current state:

set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable -value (-not ([bool](get-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable).proxyenable))

Kiwi Browser is mobile Chromium and allows installing extensions. Install Kiwi and then install "Mini JS console" Chrome extension(just search in Google and install from Chrome extensions website, uBlock also works ;). It will become available in Kiwi menu at the bottom and will show the console output for the current page.

TL;DR: A service in ng6 with providedIn: "root" cannot find the ComponentFactory when the Component is not added in the entryComponents of app.module.

This problem can also occur if you are using angular 6 in combination with dynamically creating a Component in a service!

For example, creating an Overlay:

@Injectable({
  providedIn: "root"
})
export class OverlayService {

  constructor(private _overlay: Overlay) {}

  openOverlay() {
    const overlayRef = this._createOverlay();
    const portal = new ComponentPortal(OverlayExampleComponent);

    overlayRef.attach(portal).instance;
  }
}

The Problem is the

providedIn: "root"

definition, which provides this service in app.module.

So if your service is located in, for example, the "OverlayModule", where you also declared the OverlayExampleComponent and added it to the entryComponents, the service cannot find the ComponentFactory for OverlayExampleComponent.

If you can use inline styles, then you can do it purely with CSS.

I am using this for doing CSS on the next element when the previous one is visible:

div[style='display: block;'] + table {
  filter: blur(3px);
}

I learned about order with the following example which then confused me for a long time:

set.seed(1234)

ID        = 1:10
Age       = round(rnorm(10, 50, 1))
diag      = c("Depression", "Bipolar")
Diagnosis = sample(diag, 10, replace=TRUE)

data = data.frame(ID, Age, Diagnosis)

databyAge = data[order(Age),]
databyAge

The only reason this example works is because order is sorting by the vector Age, not by the column named Age in the data frame data.

To see this create an identical data frame using read.table with slightly different column names and without making use of any of the above vectors:

my.data <- read.table(text = '

  id age  diagnosis
   1  49 Depression
   2  50 Depression
   3  51 Depression
   4  48 Depression
   5  50 Depression
   6  51    Bipolar
   7  49    Bipolar
   8  49    Bipolar
   9  49    Bipolar
  10  49 Depression

', header = TRUE)

The above line structure for order no longer works because there is no vector named age:

databyage = my.data[order(age),]

The following line works because order sorts on the column age in my.data.

databyage = my.data[order(my.data$age),]

I thought this was worth posting given how confused I was by this example for so long. If this post is not deemed appropriate for the thread I can remove it.

EDIT: May 13, 2014

Below is a generalized way of sorting a data frame by every column without specifying column names. The code below shows how to sort from left to right or by right to left. This works if every column is numeric. I have not tried with a character column added.

I found the do.call code a month or two ago in an old post on a different site, but only after extensive and difficult searching. I am not sure I could relocate that post now. The present thread is the first hit for ordering a data.frame in R. So, I thought my expanded version of that original do.call code might be useful.

set.seed(1234)

v1  <- c(0,0,0,0, 0,0,0,0, 1,1,1,1, 1,1,1,1)
v2  <- c(0,0,0,0, 1,1,1,1, 0,0,0,0, 1,1,1,1)
v3  <- c(0,0,1,1, 0,0,1,1, 0,0,1,1, 0,0,1,1)
v4  <- c(0,1,0,1, 0,1,0,1, 0,1,0,1, 0,1,0,1)

df.1 <- data.frame(v1, v2, v3, v4) 
df.1

rdf.1 <- df.1[sample(nrow(df.1), nrow(df.1), replace = FALSE),]
rdf.1

order.rdf.1 <- rdf.1[do.call(order, as.list(rdf.1)),]
order.rdf.1

order.rdf.2 <- rdf.1[do.call(order, rev(as.list(rdf.1))),]
order.rdf.2

rdf.3 <- data.frame(rdf.1$v2, rdf.1$v4, rdf.1$v3, rdf.1$v1) 
rdf.3

order.rdf.3 <- rdf.1[do.call(order, as.list(rdf.3)),]
order.rdf.3

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

With VS 2013 Express this key does not exist. What I see is HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0 and there is no mention of Text Editor under that.

Here is a snippet I wrote; to ask for users' password and set it in /etc/passwd. You can manipulate it a little probably to get what you need:

echo -n " Please enter the password for the given user: "
read userPass
useradd $userAcct && echo -e "$userPass\n$userPass\n" | passwd $userAcct > /dev/null 2>&1 && echo " User account has been created." || echo " ERR -- User account creation failed!"

All tags must have enclosing tags. In my case, the hr and input elements weren't closed properly.

Parent Error was: JSX element 'div' has no corresponding closing tag, due to code below:

<hr class="my-4">
<input
  type="password"
  id="inputPassword"
  class="form-control"
  placeholder="Password"
  required
 >

Fix:

<hr class="my-4"/>
<input
 type="password"
 id="inputPassword"
 class="form-control"
 placeholder="Password"
 required
/>

The parent elements will show errors due to child element errors. Therefore, start investigating from most inner elements up to the parent ones.

SVG 1.2 Tiny added text wrapping, but most implementations of SVG that you will find in the browser (with the exception of Opera) have not implemented this feature. It's typically up to you, the developer, to position text manually.

The SVG 1.1 specification provides a good overview of this limitation, and the possible solutions to overcome it:

Each ‘text’ element causes a single string of text to be rendered. SVG performs no automatic line breaking or word wrapping. To achieve the effect of multiple lines of text, use one of the following methods:

• The author or authoring package needs to pre-compute the line breaks and use multiple ‘text’ elements (one for each line of text).
• The author or authoring package needs to pre-compute the line breaks and use a single ‘text’ element with one or more ‘tspan’ child elements with appropriate values for attributes ‘x’, ‘y’, ‘dx’ and ‘dy’ to set new start positions for those characters who start new lines. (This approach allows user text selection across multiple lines of text -- see Text selection and clipboard operations.)
• Express the text to be rendered in another XML namespace such as XHTML [XHTML] embedded inline within a ‘foreignObject’ element. (Note: the exact semantics of this approach are not completely defined at this time.)

http://www.w3.org/TR/SVG11/text.html#Introduction

As a primitive, text wrapping can be simulated by using the dy attribute and tspan elements, and as mentioned in the spec, some tools can automate this. For example, in Inkscape, select the shape you want, and the text you want, and use Text -> Flow into Frame. This will allow you to write your text, with wrapping, which will wrap based on the bounds of the shape. Also, make sure you follow these instructions to tell Inkscape to maintain compatibility with SVG 1.1: http://wiki.inkscape.org/wiki/index.php/FAQ#What_about_flowed_text.3F

Furthermore, there are some JavaScript libraries that can be used to dynamically automate text wrapping: http://www.carto.net/papers/svg/textFlow/

It's interesting to note CSVG's solution to wrapping a shape to a text element (e.g. see their "button" example), although it's important to mention that their implementation is not usable in a browser: http://www.csse.monash.edu.au/~clm/csvg/about.html

I'm mentioning this because I have developed a CSVG-inspired library that allows you to do similar things and does work in web browsers, although I haven't released it yet.

The communication link between the driver and the data source to which the driver was attempting to connect failed before the function completed processing. So usually its a network error. This could be caused by packet drops or badly configured Firewall/Switch.

Here's something that might be interesting for developers hacking (minified or obfuscated) JavaScript more frequently.

You can build your own CLI JavaScript beautifier in under 5 mins and have it handy on the command-line. You'll need Mozilla Rhino, JavaScript file of some of the JS beautifiers available online, small hack and a script file to wrap it all up.

I wrote an article explaining the procedure: Command-line JavaScript beautifier implemented in JavaScript.

As for least squares fit, here are a couple other things to experiment with:

1. Just because it's least squares fit doesn't mean that it has to be linear. You can least-squares-fit a quadratic curve to the data, then this would fit a scenario in which the user is accelerating. (Note that by least squares fit I mean using the coordinates as the dependent variable and time as the independent variable.)

2. You could also try weighting the data points based on reported accuracy. When the accuracy is low weight those data points lower.

3. Another thing you might want to try is rather than display a single point, if the accuracy is low display a circle or something indicating the range in which the user could be based on the reported accuracy. (This is what the iPhone's built-in Google Maps application does.)

The order of execution of ng-click and ng-model is ambiguous since they do not define clear priorities. Instead you should use ng-change or a $watch on the $scope to ensure that you obtain the correct values of the model variable.

In your case, this should work:

<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">

You don't have an element with the id u.That's why the error occurs. Note that the global variable document.getElementById("u").value means you are trying to get the value of input element with name u and its not defined in your code.

I found I could solve this by simply putting the two side by side tables inside of a third table that was centered. Here is the code

I added two lines of code at the top and bottom of the two existing tables

Had the same issue on 64 bit win7 machine on company network behind proxy with automatically detected settings.

After a number of trials and failures the following workaround proved to be successful:

• sharing my phone's wifi internet connection via USB

Best regards, Robert

You can do it this way as well....

@Component
@PropertySource("classpath:application.properties")
public class ConfigProperties {

    @Autowired
    private Environment env;

    public String getConfigValue(String configKey){
        return env.getProperty(configKey);
    }
}

Then wherever you want to read from application.properties, just pass the key to getConfigValue method.

@Autowired
ConfigProperties configProp;

// Read server.port from app.prop
String portNumber = configProp.getConfigValue("server.port"); 

If you don't like "verbosity" you can always wrap your code in a short method:

private void msgbox(String s){
   JOptionPane.showMessageDialog(null, s);
}

and the usage:

msgbox("don't touch that!");

You can make bar a function making it a method.

Foo.bar = function(passvariable){  };

As a property it would just be assigned a string, data type or boolean

Foo.bar = "a place";

It sounds like Apache is warning you that you have multiple <VirtualHost> sections with the same IP address and port... as far as getting it to work without warnings, I think you would need to use something like Server Name Indication (SNI), a way of identifying the hostname requested as part of the SSL handshake. Basically it lets you do name-based virtual hosting over SSL, but I'm not sure how well it's supported by browsers. Other than something like SNI, you're basically limited to one SSL-enabled domain name for each IP address you expose to the public internet.

Of course, if you are able to access the websites properly, you'll probably be fine ignoring the warnings. These particular ones aren't very serious - they're mainly an indication of what to look at if you are experiencing problems

Maybe too late, but I'd cast 0/1 as bit to make the datatype eventually becomes True/False when consumed by .NET framework:

SELECT   EntityId, 
         EntityName, 
         CASE 
            WHEN EntityProfileIs IS NULL 
            THEN CAST(0 as bit) 
            ELSE CAST(1 as bit) END AS HasProfile
FROM      Entities
LEFT JOIN EntityProfiles ON EntityProfiles.EntityId = Entities.EntityId`

Just use constraint layout inside NestedScrollView or ScrollView.

<android.support.v4.widget.NestedScrollView
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/white">

 </android.support.constraint.ConstraintLayout>

</android.support.v4.widget.NestedScrollView>

thats it. enjoy your coding.

Rollback-and-reapply is realy simple solution, but it can help only with the last commit. Mercurial Queues is much more powerful thing (note that you need to enable Mercurial Queues Extension in order to use "hg q*" commands).

</style>

once I need to fix the height of a particular valued row by using inline CSS as following..

<tr><td colspan="4" style="height: 10px;">xxxyyyzzz</td></tr>

I have implemented MultipartReader NuGet package for ASP.NET 4 for reading multipart form data. It is based on Multipart Form Data Parser, but it supports more than one file.

This API has been available for a long time and enables to get access to market data (including live) if you are running a Bloomberg Terminal or have access to a Bloomberg Server, which is chargeable.

The only difference is that the API (not its code) has been open sourced, so it can now be used as a dependency in an open source project for example, without any copyrights issues, which was not the case before.

I was trying to create a new project in Visual Studio 2017 today (recently upgraded from Visual Studio 2015) and noticed new set of choices for the type of project. Either they're new or it's been a while since I started a new project!! :)

I came across this documentation link and found it very useful, so I am sharing. The details of the bullets are also provided in the article. I am just posting bullets here:

You should use .NET Core for your server application when:

You have cross-platform needs.
You are targeting microservices.
You are using Docker containers.
You need high performance and scalable systems.
You need side by side of .NET versions by application.

You should use .NET Framework for your server application when:

Your application currently uses .NET Framework (recommendation is to extend instead of migrating)
You need to use third-party .NET libraries or NuGet packages not available for .NET Core.
You need to use .NET technologies that are not available for .NET Core.
You need to use a platform that doesn’t support .NET Core.

This link provides a glossary of .NET terms.

EDIT 10/7/2020 Check out .NET 5.0 - "... just one .NET going forward, and you will be able to use it to target Windows, Linux, macOS, iOS, Android, tvOS, watchOS and WebAssembly and more" It's supposed to be released November 2020.

There are several methods that can be useful to achieve field-specific results. One can be through the source method. And another method that can also be useful to receive cleaner and more summarized answers according to our interests is filter_path:

Document Json:

"hits" : [
  {
    "_index" : "xxxxxx",
    "_type" : "_doc",
    "_id" : "xxxxxx",
    "_score" : xxxxxx,
    "_source" : {
      "year" : 2020,
      "created_at" : "2020-01-29",
      "url" : "www.github.com/mbarr0987",
      "name":"github"
    }
  }

Query:

GET bot1/_search?filter_path=hits.hits._source.url
{
  "query": {
    "bool": {
      "must": [
        {"term": {"name.keyword":"github" }}
       ]
    }
  }
}

Output:

{
  "hits" : {
    "hits" : [
      {
        "_source" : {
          "url" : "www.github.com/mbarr0987"
            }
          }
      ]
   }
}

if you are just getting a single value out of either (not in a loop) then both do bounds checking (you're in managed code remember) it's just the list does it twice. See the notes later for why this is likely not a big deal.

If you are using your own for(int int i = 0; i < x.[Length/Count];i++) then the key difference is as follows:

• Array:
  • bounds checking is removed
• Lists
  • bounds checking is performed

If you are using foreach then the key difference is as follows:

• Array:
  • no object is allocated to manage the iteration
  • bounds checking is removed
• List via a variable known to be List.
  • the iteration management variable is stack allocated
  • bounds checking is performed
• List via a variable known to be IList.
  • the iteration management variable is heap allocated
  • bounds checking is performed also Lists values may not be altered during the foreach whereas the array's can be.

The bounds checking is often no big deal (especially if you are on a cpu with a deep pipeline and branch prediction - the norm for most these days) but only your own profiling can tell you if that is an issue. If you are in parts of your code where you are avoiding heap allocations (good examples are libraries or in hashcode implementations) then ensuring the variable is typed as List not IList will avoid that pitfall. As always profile if it matters.

I created dummy sample for Google Maps v2 Android with Kotlin and AndroidX

You can find complete project here: github-link

    setContentView(R.layout.activity_main)

    with(mapView) {
        // Initialise the MapView
        onCreate(null)
        // Set the map ready callback to receive the GoogleMap object
        getMapAsync{
            MapsInitializer.initialize(applicationContext)
            setMapLocation(it)

Write below code into your MainActivity file after setContentView(R.layout.activity_main);

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

And below import statement into your java file.

import android.os.StrictMode;

For external link simply use an achor in place of Link:

<a rel="noopener noreferrer" href="http://url.com" target="_blank">Link Here</a>

In Code:

Url.Content("~/");

MVC3 Razor Syntax:

@Url.Content("~/")

If you think about it, a body XRay scan (at the medical center) too needs this kind of measurement for estimating size of tumors. So they place a 1 Dollar Coin on the body, to do a comparative measurement.

Even newspaper is printed with some marks on the corners.

You need a reference to measure. May be you can get your person to wear a cap which has a few bright green circles. Once you recognize the size of the circle you can comparatively measure the remaining.

Or you can create a transparent 1 inch circle which will superimpose on the face, move the camera toward/away the face, aim your superimposed circle on that bright green circle on the cap. Then on your photo will be as per scale.

I found a workaround over on GitHub: https://github.com/jmhofer/eCobertura/issues/8

For those who don't want to click the link, here's the text of the comment:

Good workaround: Create a run configuration with a filter, that excludes everything ("*") and let it run just a single test. Name it "Undo coverage".

I did this and it worked quite well in Eclipse Juno.

Credit for this goes to UsulSK.

You could try this command, it should build and run the app (so .apk should be created) :

phonegap local run android

npm i config

In config/default.json
{
    "app": {
        "port": 3000
    },
    "db": {
        "port": 27017,
        "name": "dev_db_name"
    }
}

In config/production.json
{
    "app": {
        "port": 4000
    },
    "db": {
        "port": 27000,
        "name": "prod_db_name"
    }
}

In index.js

const config = require('config');

let appPort = config.get('app.port');
console.log(`Application port: ${appPort}`);

let dbPort = config.get('db.port');
console.log(`Database port: ${dbPort}`);

let dbName = config.get('db.name');
console.log(`Database name: ${dbName}`);

console.log('NODE_ENV: ' + config.util.getEnv('NODE_ENV'));

$ node index.js
Application port: 3000
Database port: 27017
Database name: dev_db_name
NODE_ENV: development

For production
$ set NODE_ENV=production
$ node index.js
Application port: 4000
Database port: 27000
Database name: prod_db_name
NODE_ENV: production

Another way is to use prop (jQuery >= 1.6):

$("input[type=radio]").click(function () {
    if($(this).prop("checked")) { alert("checked!"); }
});

To pass a string to the view as the Model, you can do:

public ActionResult Index()
{
    string myString = "This is my string";
    return View((object)myString);
}

You must cast it to an object so that MVC doesn't try to load the string as the view name, but instead pass it as the model. You could also write:

return View("Index", myString);

.. which is a bit more verbose.

Then in your view, just type it as a string:

@model string

<p>Value: @Model</p>

Then you can manipulate Model how you want.

For accessing it from a Layout page, it might be better to create an HtmlExtension for this:

public static string GetThemePath(this HtmlHelper helper)
{
    return "/path-to-theme";
}

Then inside your layout page:

<p>Value: @Html.GetThemePath()</p>

Hopefully you can apply this to your own scenario.

Edit: explicit HtmlHelper code:

namespace <root app namespace>
{
    public static class Helpers
    {
        public static string GetThemePath(this HtmlHelper helper)
        {
            return System.Web.Hosting.HostingEnvironment.MapPath("~") + "/path-to-theme";
        }
    }
}

Then in your view:

@{
    var path = Html.GetThemePath();
    // .. do stuff
}

Or: <p>Path: @Html.GetThemePath()</p>

Edit 2:

As discussed, the Helper will work if you add a @using statement to the top of your view, with the namespace pointing to the one that your helper is in.

dovescrywolf gave tip as a comment on article linked by Davide Inglima

It was was very useful for me on MacOS.

• Close Eclipse if it's opened.

• Open Termnal (bash console) and do below things:

  $ pwd /Users/You/YourEclipseInstalationDirectory  
  $ cd Eclipse.app/Contents/MacOS/  
  $ echo "-Duser.name=Your Name" >> eclipse.ini  
  $ cat eclipse.ini
  

• Close Terminal and start/open Eclipse again.

When you call a Linq statement like this:

// x = new List<string>();
var count = x.Count(s => s.StartsWith("x"));

You are actually using an extension method in the System.Linq namespace, so what the compiler translates this into is:

var count = Enumerable.Count(x, s => s.StartsWith("x"));

So the error you are getting above is because the first parameter, source (which would be x in the sample above) is null.

You must set your query base to the DN of the user in question, then set your filter to the DN of the group you're wondering if they're a member of. To see if jdoe is a member of the office group then your query will look something like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host '(memberof=cn=officegroup,dc=example,dc=local)'

If you want to see ALL the groups he's a member of, just request only the 'memberof' attribute in your search, like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host **memberof**

Hi These two lines worked for me.

contentType:"application/json; charset=utf-8", dataType:"json"

 $.ajax({
            type: "POST",
            url: "/v1/candidates",
            data: obj,
            **contentType:"application/json; charset=utf-8",
            dataType:"json",**
            success: function (data) {
                table.row.add([
                    data.name, data.title
                ]).draw(false);
            }

Thanks, Prashant

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master

Change to this:

@{ Response.Redirect("~/HOME/NoResults");}

normally, Maxim Donnie's method can find the reason. But I encountered one 400 bad request will not log to err_log. I found the reason with the help with tcpdump

You can iterate over values() of enum and compare integer value of enum with given id like below:

public enum  TestEnum {
    None(0),
    Value1(1),
    Value2(2),
    Value3(3),
    Value4(4),
    Value5(5);

    private final int value;
    private TestEnum(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }

    public static TestEnum  getEnum(int value){
        for (TestEnum e:TestEnum.values()) {
            if(e.getValue() == value)
                return e;
        }
        return TestEnum.None;//For values out of enum scope
    }
}

And use just like this:
TestEnum x = TestEnum.getEnum(4);//Will return TestEnum.Value4
I hope this helps ;)

I think you have to use the GetValueOrDefault-Methode. The behaviour with ToString("yy...") is not defined if the instance is null.

dt2.GetValueOrDefault().ToString("yyy...");

This looks like a problem with line endings in your code. If you're going to be using all these other scientific packages, you may as well use Pandas for the CSV reading part, which is both more robust and more useful than just the csv module:

import pandas
colnames = ['year', 'name', 'city', 'latitude', 'longitude']
data = pandas.read_csv('test.csv', names=colnames)

If you want your lists as in the question, you can now do:

names = data.name.tolist()
latitude = data.latitude.tolist()
longitude = data.longitude.tolist()

When you create your table, put your td with class = "suma"

$(function(){   

   //funcion suma todo

   var sum = 0;
   $('.suma').each(function(x,y){
       sum += parseInt($(this).text());                                   
   })           
   $('#lblTotal').text(sum);   

   // funcion suma por check                                           

    $( "input:checkbox").change(function(){
    if($(this).is(':checked')){     
        $(this).parent().parent().find('td:last').addClass('suma2');
   }else{       
        $(this).parent().parent().find('td:last').removeClass('suma2');
   }    
   suma2Total();                                                           
   })                                                      

   function suma2Total(){
      var sum2 = 0;
      $('.suma2').each(function(x,y){
        sum2 += parseInt($(this).text());       
      })
      $('#lblTotal2').text(sum2);                                              
   }

For me it was a permission problem. Somebody removed write permissions on the folder for the user account under which the application was running.

I know it is been answered long time ago, but i would like to share this also:

This code works very well:

SQLiteDatabase db = this.getReadableDatabase();
long taskCount = DatabaseUtils.queryNumEntries(db, TABLE_TODOTASK);

BUT what if i dont want to count all rows and i have a condition to apply?

DatabaseUtils have another function for this: DatabaseUtils.longForQuery

long taskCount = DatabaseUtils.longForQuery(db, "SELECT COUNT (*) FROM " + TABLE_TODOTASK + " WHERE " + KEY_TASK_TASKLISTID + "=?",
         new String[] { String.valueOf(tasklist_Id) });

The longForQuery documentation says:

Utility method to run the query on the db and return the value in the first column of the first row.

public static long longForQuery(SQLiteDatabase db, String query, String[] selectionArgs)

It is performance friendly and save you some time and boilerplate code

Hope this will help somebody someday :)

I hope your database is at least UTF-8. Then you will need to run yourstring.encode('utf-8') before you try putting it into the database.

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_
_x000D_
  }_x000D_

^{First a disclaimer beforehand: the posted code snippets are all basic examples. You'll need to handle trivial IOExceptions and RuntimeExceptions like NullPointerException, ArrayIndexOutOfBoundsException and consorts yourself.}

Preparing

We first need to know at least the URL and the charset. The parameters are optional and depend on the functional requirements.

String url = "http://example.com";
String charset = "UTF-8";  // Or in Java 7 and later, use the constant: java.nio.charset.StandardCharsets.UTF_8.name()
String param1 = "value1";
String param2 = "value2";
// ...

String query = String.format("param1=%s&param2=%s", 
     URLEncoder.encode(param1, charset), 
     URLEncoder.encode(param2, charset));

The query parameters must be in name=value format and be concatenated by &. You would normally also URL-encode the query parameters with the specified charset using URLEncoder#encode().

^{The String#format() is just for convenience. I prefer it when I would need the String concatenation operator + more than twice.}

Firing an HTTP GET request with (optionally) query parameters

It's a trivial task. It's the default request method.

URLConnection connection = new URL(url + "?" + query).openConnection();
connection.setRequestProperty("Accept-Charset", charset);
InputStream response = connection.getInputStream();
// ...

Any query string should be concatenated to the URL using ?. The Accept-Charset header may hint the server what encoding the parameters are in. If you don't send any query string, then you can leave the Accept-Charset header away. If you don't need to set any headers, then you can even use the URL#openStream() shortcut method.

InputStream response = new URL(url).openStream();
// ...

Either way, if the other side is an HttpServlet, then its doGet() method will be called and the parameters will be available by HttpServletRequest#getParameter().

For testing purposes, you can print the response body to stdout as below:

try (Scanner scanner = new Scanner(response)) {
    String responseBody = scanner.useDelimiter("\\A").next();
    System.out.println(responseBody);
}

Firing an HTTP POST request with query parameters

Setting the URLConnection#setDoOutput() to true implicitly sets the request method to POST. The standard HTTP POST as web forms do is of type application/x-www-form-urlencoded wherein the query string is written to the request body.

URLConnection connection = new URL(url).openConnection();
connection.setDoOutput(true); // Triggers POST.
connection.setRequestProperty("Accept-Charset", charset);
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=" + charset);

try (OutputStream output = connection.getOutputStream()) {
    output.write(query.getBytes(charset));
}

InputStream response = connection.getInputStream();
// ...

Note: whenever you'd like to submit a HTML form programmatically, don't forget to take the name=value pairs of any <input type="hidden"> elements into the query string and of course also the name=value pair of the <input type="submit"> element which you'd like to "press" programmatically (because that's usually been used in the server side to distinguish if a button was pressed and if so, which one).

You can also cast the obtained URLConnection to HttpURLConnection and use its HttpURLConnection#setRequestMethod() instead. But if you're trying to use the connection for output you still need to set URLConnection#setDoOutput() to true.

HttpURLConnection httpConnection = (HttpURLConnection) new URL(url).openConnection();
httpConnection.setRequestMethod("POST");
// ...

Either way, if the other side is an HttpServlet, then its doPost() method will be called and the parameters will be available by HttpServletRequest#getParameter().

Actually firing the HTTP request

You can fire the HTTP request explicitly with URLConnection#connect(), but the request will automatically be fired on demand when you want to get any information about the HTTP response, such as the response body using URLConnection#getInputStream() and so on. The above examples does exactly that, so the connect() call is in fact superfluous.

Gathering HTTP response information

1. HTTP response status:

You need an HttpURLConnection here. Cast it first if necessary.

    int status = httpConnection.getResponseCode();

2. HTTP response headers:

    for (Entry<String, List<String>> header : connection.getHeaderFields().entrySet()) {
        System.out.println(header.getKey() + "=" + header.getValue());
    }
   

3. HTTP response encoding:

When the Content-Type contains a charset parameter, then the response body is likely text based and we'd like to process the response body with the server-side specified character encoding then.

    String contentType = connection.getHeaderField("Content-Type");
    String charset = null;

    for (String param : contentType.replace(" ", "").split(";")) {
        if (param.startsWith("charset=")) {
            charset = param.split("=", 2)[1];
            break;
        }
    }

    if (charset != null) {
        try (BufferedReader reader = new BufferedReader(new InputStreamReader(response, charset))) {
            for (String line; (line = reader.readLine()) != null;) {
                // ... System.out.println(line) ?
            }
        }
    } else {
        // It's likely binary content, use InputStream/OutputStream.
    }

Maintaining the session

The server side session is usually backed by a cookie. Some web forms require that you're logged in and/or are tracked by a session. You can use the CookieHandler API to maintain cookies. You need to prepare a CookieManager with a CookiePolicy of ACCEPT_ALL before sending all HTTP requests.

// First set the default cookie manager.
CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));

// All the following subsequent URLConnections will use the same cookie manager.
URLConnection connection = new URL(url).openConnection();
// ...

connection = new URL(url).openConnection();
// ...

connection = new URL(url).openConnection();
// ...

Note that this is known to not always work properly in all circumstances. If it fails for you, then best is to manually gather and set the cookie headers. You basically need to grab all Set-Cookie headers from the response of the login or the first GET request and then pass this through the subsequent requests.

// Gather all cookies on the first request.
URLConnection connection = new URL(url).openConnection();
List<String> cookies = connection.getHeaderFields().get("Set-Cookie");
// ...

// Then use the same cookies on all subsequent requests.
connection = new URL(url).openConnection();
for (String cookie : cookies) {
    connection.addRequestProperty("Cookie", cookie.split(";", 2)[0]);
}
// ...

The split(";", 2)[0] is there to get rid of cookie attributes which are irrelevant for the server side like expires, path, etc. Alternatively, you could also use cookie.substring(0, cookie.indexOf(';')) instead of split().

Streaming mode

The HttpURLConnection will by default buffer the entire request body before actually sending it, regardless of whether you've set a fixed content length yourself using connection.setRequestProperty("Content-Length", contentLength);. This may cause OutOfMemoryExceptions whenever you concurrently send large POST requests (e.g. uploading files). To avoid this, you would like to set the HttpURLConnection#setFixedLengthStreamingMode().

httpConnection.setFixedLengthStreamingMode(contentLength);

But if the content length is really not known beforehand, then you can make use of chunked streaming mode by setting the HttpURLConnection#setChunkedStreamingMode() accordingly. This will set the HTTP Transfer-Encoding header to chunked which will force the request body being sent in chunks. The below example will send the body in chunks of 1KB.

httpConnection.setChunkedStreamingMode(1024);

User-Agent

It can happen that a request returns an unexpected response, while it works fine with a real web browser. The server side is probably blocking requests based on the User-Agent request header. The URLConnection will by default set it to Java/1.6.0_19 where the last part is obviously the JRE version. You can override this as follows:

connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36"); // Do as if you're using Chrome 41 on Windows 7.

Use the User-Agent string from a recent browser.

Error handling

If the HTTP response code is 4nn (Client Error) or 5nn (Server Error), then you may want to read the HttpURLConnection#getErrorStream() to see if the server has sent any useful error information.

InputStream error = ((HttpURLConnection) connection).getErrorStream();

If the HTTP response code is -1, then something went wrong with connection and response handling. The HttpURLConnection implementation is in older JREs somewhat buggy with keeping connections alive. You may want to turn it off by setting the http.keepAlive system property to false. You can do this programmatically in the beginning of your application by:

System.setProperty("http.keepAlive", "false");

Uploading files

You'd normally use multipart/form-data encoding for mixed POST content (binary and character data). The encoding is in more detail described in RFC2388.

String param = "value";
File textFile = new File("/path/to/file.txt");
File binaryFile = new File("/path/to/file.bin");
String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value.
String CRLF = "\r\n"; // Line separator required by multipart/form-data.
URLConnection connection = new URL(url).openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);

try (
    OutputStream output = connection.getOutputStream();
    PrintWriter writer = new PrintWriter(new OutputStreamWriter(output, charset), true);
) {
    // Send normal param.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"param\"").append(CRLF);
    writer.append("Content-Type: text/plain; charset=" + charset).append(CRLF);
    writer.append(CRLF).append(param).append(CRLF).flush();

    // Send text file.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"textFile\"; filename=\"" + textFile.getName() + "\"").append(CRLF);
    writer.append("Content-Type: text/plain; charset=" + charset).append(CRLF); // Text file itself must be saved in this charset!
    writer.append(CRLF).flush();
    Files.copy(textFile.toPath(), output);
    output.flush(); // Important before continuing with writer!
    writer.append(CRLF).flush(); // CRLF is important! It indicates end of boundary.

    // Send binary file.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"binaryFile\"; filename=\"" + binaryFile.getName() + "\"").append(CRLF);
    writer.append("Content-Type: " + URLConnection.guessContentTypeFromName(binaryFile.getName())).append(CRLF);
    writer.append("Content-Transfer-Encoding: binary").append(CRLF);
    writer.append(CRLF).flush();
    Files.copy(binaryFile.toPath(), output);
    output.flush(); // Important before continuing with writer!
    writer.append(CRLF).flush(); // CRLF is important! It indicates end of boundary.

    // End of multipart/form-data.
    writer.append("--" + boundary + "--").append(CRLF).flush();
}

If the other side is an HttpServlet, then its doPost() method will be called and the parts will be available by HttpServletRequest#getPart() (note, thus not getParameter() and so on!). The getPart() method is however relatively new, it's introduced in Servlet 3.0 (Glassfish 3, Tomcat 7, etc). Prior to Servlet 3.0, your best choice is using Apache Commons FileUpload to parse a multipart/form-data request. Also see this answer for examples of both the FileUpload and the Servelt 3.0 approaches.

Dealing with untrusted or misconfigured HTTPS sites

Sometimes you need to connect an HTTPS URL, perhaps because you're writing a web scraper. In that case, you may likely face a javax.net.ssl.SSLException: Not trusted server certificate on some HTTPS sites who doesn't keep their SSL certificates up to date, or a java.security.cert.CertificateException: No subject alternative DNS name matching [hostname] found or javax.net.ssl.SSLProtocolException: handshake alert: unrecognized_name on some misconfigured HTTPS sites.

The following one-time-run static initializer in your web scraper class should make HttpsURLConnection more lenient as to those HTTPS sites and thus not throw those exceptions anymore.

static {
    TrustManager[] trustAllCertificates = new TrustManager[] {
        new X509TrustManager() {
            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return null; // Not relevant.
            }
            @Override
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
                // Do nothing. Just allow them all.
            }
            @Override
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
                // Do nothing. Just allow them all.
            }
        }
    };

    HostnameVerifier trustAllHostnames = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true; // Just allow them all.
        }
    };

    try {
        System.setProperty("jsse.enableSNIExtension", "false");
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCertificates, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HttpsURLConnection.setDefaultHostnameVerifier(trustAllHostnames);
    }
    catch (GeneralSecurityException e) {
        throw new ExceptionInInitializerError(e);
    }
}

Hope this helps. Good luck!

Runnable is an interface defined as so:

interface Runnable {
    public void run();
}

To make a class which uses it, just define the class as (public) class MyRunnable implements Runnable {

It can be used without even making a new Thread. It's basically your basic interface with a single method, run, that can be called.

If you make a new Thread with runnable as it's parameter, it will call the run method in a new Thread.

It should also be noted that Threads implement Runnable, and that is called when the new Thread is made (in the new thread). The default implementation just calls whatever Runnable you handed in the constructor, which is why you can just do new Thread(someRunnable) without overriding Thread's run method.

lines2 = lines.split.join("\n")

As you are using asp:Button which is a server control, post back will happen to avoid that go for html button,

Type to

First, describe nodes and see if it reports anything:

$ kubectl describe nodes

Look for conditions, capacity and allocatable:

Conditions:
  Type              Status
  ----              ------
  OutOfDisk         False
  MemoryPressure    False
  DiskPressure      False
  Ready             True
Capacity:
 cpu:       2
 memory:    2052588Ki
 pods:      110
Allocatable:
 cpu:       2
 memory:    1950188Ki
 pods:      110

If everything is alright here, SSH into the node and observe kubelet logs to see if it reports anything. Like certificate erros, authentication errors etc.

If kubelet is running as a systemd service, you can use

$ journalctl -u kubelet

Warning: Note that English is not restricted to just A-Z.

Try this to remove everything except a-z, A-Z and 0-9:

$result = preg_replace("/[^a-zA-Z0-9]+/", "", $s);

If your definition of alphanumeric includes letters in foreign languages and obsolete scripts then you will need to use the Unicode character classes.

Try this to leave only A-Z:

$result = preg_replace("/[^A-Z]+/", "", $s);

The reason for the warning is that words like résumé contains the letter é that won't be matched by this. If you want to match a specific list of letters adjust the regular expression to include those letters. If you want to match all letters, use the appropriate character classes as mentioned in the comments.

You can iterate over the row data

$('#button').click(function () {
    var ids = $.map(table.rows('.selected').data(), function (item) {
        return item[0]
    });
    console.log(ids)
    alert(table.rows('.selected').data().length + ' row(s) selected');
});

You can try this:

on Server:

adding new group to /etc/group like (example)

mygroup:1001:michael,nir

create new git repository:

mkdir /srv/git
cd /srv/git
mkdir project_dir
cd project_dir
git --bare init (initial git repository )
chgrp -R mygroup objects/ refs/ (change owner of directory )
chmod -R g+w objects/ refs/ (give permission write)

on Client:

mkdir my_project
cd my_project
touch .gitignore
git init
git add .
git commit -m "Initial commit"
git remote add origin [email protected]:/path/to/my_project.git
git push origin master

(Thanks Josh Lindsey for client side)

after Client, do on Server this commands:

cd /srv/git/project_dir
chmod -R g+w objects/ refs/

If got this error after git pull:

There is no tracking information for the current branch. Please specify which branch you want to merge with. See git-pull(1) for details

git pull <remote> <branch>
If you wish to set tracking information for this branch you can do so with:

git branch --set-upstream new origin/<branch>

try:

git push -u origin master

It will help.

While I agree with the comments about passing in variables from your controller you can also register undefined functions when setting up the twig environment

$twig->registerUndefinedFunctionCallback(function ($name) {
        // security
        $allowed = false;
        switch ($name) {
            // example of calling a wordpress function
            case 'get_admin_page_title':
                $allowed = true;
                break;
        }

        if ($allowed && function_exists($name)) {
            return new Twig_Function_Function($name);
        }

        return false;
    });

This is from the Twig recipe page

Haven't tried calling a function on an object as the original question requested

Suppose we want to run your Django web server (in Linux) that there is space between your path (path='/home/<you>/<first-path-section> <second-path-section>'), so do the following:

import subprocess

args = ['{}/manage.py'.format('/home/<you>/<first-path-section> <second-path-section>'), 'runserver']
res = subprocess.Popen(args, stdout=subprocess.PIPE)
output, error_ = res.communicate()

if not error_:
    print(output)
else:
    print(error_)

[Note]:

• Do not forget accessing permission: chmod 755 -R <'yor path'>
• manage.py is exceutable: chmod +x manage.py

After struggling with this myself, I've come to implement FileReader for browsers that support it (Chrome, Firefox and the as-yet unreleased Safari 6), and a PHP script that echos back POSTed file data as Base64-encoded data for the other browsers.

Placing @EdChum's very nice answer into a function count_unique_index. The unique method only works on pandas series, not on data frames. The function below reproduces the behavior of the unique function in R:

unique returns a vector, data frame or array like x but with duplicate elements/rows removed.

And adds a count of the occurrences as requested by the OP.

df1 = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],                                                                                             
                    'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})                                                                                               
def count_unique_index(df, by):                                                                                                                                                 
    return df.groupby(by).size().reset_index().rename(columns={0:'count'})

This is a "PHP Notice", so you could in theory ignore it. Change php.ini:

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED

To

error_reporting = E_ALL & ~E_NOTICE

This show all errors, except for notices.

With the AppendLine method.

Probably too late to comment but here's what I did when I ran into issues with setting php PATH for my XAMPP installation on Mac OSX

1. Open up the file .bash_profile (found under current user folder) using the available text editor.
2. Add the path as below:

export PATH=/path/to/your/php/installation/bin:leave/rest/of/the/stuff/untouched/:$PATH

3. Save your .bash_profile and re-start your Mac.

Explanation: Terminal / Mac tries to run a search on the PATHS it knows about, in a hope of finding the program, when user initiates a program from the "Terminal", hence the trick here is to make the terminal find the php, the user intends to, by pointing it to the user's version of PHP at some bin folder, installed by the user.

Worked for me :)

P.S I'm still a lost sheep around my new Computer ;)

It is possible
You just also need to apply the color to 'tbody' element as that's the table body that's been causing our trouble by peeking underneath.
table, tbody, tr, th, td{ background-color: rgba(0, 0, 0, 0.0) !important; }

You want to keep the selector, so adding/removing it won't work. Instead of writing a hard and fast CSS selectors (or two), perhaps you can just use the original selector to apply new CSS rule to that element based on some criterion:

$(".test").hover(
  if(some evaluation) {
    $(this).css('border':0);
  }
);

This problem can be caused by incorrect path to the FXML file.

If you're using absolute paths (my/package/views/view.fxml), you have to precede then with a slash:

getClass().getResource("/my/package/views/view.fxml")

You can use relative paths as well:

getClass().getResource("views/view.fxml")

In httpd.conf file you need to remove #

#LoadModule rewrite_module modules/mod_rewrite.so

after removing # line will look like this:

LoadModule rewrite_module modules/mod_rewrite.so

And Apache restart

Hera's the function UpdateWindowsList_WindowMenu() that you must call after any operations are performed on Tabs.Here windowToolStripMenuItem is the menu item added to Window Menu to menu strip.

public void UpdateWindowsList_WindowMenu()  
{  
    //get all tab pages from tabControl1  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  

    //get  windowToolStripMenuItem drop down menu items count  
    int n = windowToolStripMenuItem.DropDownItems.Count;  

    //remove all menu items from of windowToolStripMenuItem  
    for (int i = n - 1; i >=2; i--)  
    {  
        windowToolStripMenuItem.DropDownItems.RemoveAt(i);  
    }  

    //read each tabpage from tabcoll and add each tabpage text to windowToolStripMenuItem  
    foreach (TabPage tabpage in tabcoll)  
    {  
        //create Toolstripmenuitem  
        ToolStripMenuItem menuitem = new ToolStripMenuItem();  
        String s = tabpage.Text;  
        menuitem.Text = s;  

        if (tabControl1.SelectedTab == tabpage)  
        {  
            menuitem.Checked = true;  
        }  
        else  
        {  
            menuitem.Checked = false;  
        }  

        //add menuitem to windowToolStripMenuItem  
        windowToolStripMenuItem.DropDownItems.Add(menuitem);  

        //add click events to each added menuitem  
        menuitem.Click += new System.EventHandler(WindowListEvent_Click);  
    }  
}  

private void WindowListEvent_Click(object sender, EventArgs e)  
{  
    //casting ToolStripMenuItem to ToolStripItem  
    ToolStripItem toolstripitem = (ToolStripItem)sender;  

    //create collection of tabs of tabContro1  
    //check every tab text is equal to clicked menuitem then select the tab  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  
    foreach (TabPage tb in tabcoll)  
    {  
        if (toolstripitem.Text == tb.Text)  
        {  
            tabControl1.SelectedTab = tb;  
            //call UpdateWindowsList_WindowMenu() to perform changes on menuitems  
            UpdateWindowsList_WindowMenu();  
        }  
    }  
}  

This is for my comment on Andrey's answer but I cant include code in the comments.

Is you preference activity being called from you main activity? you could place this in the on resume...

@Override
protected void onResume() {
    if (!(PreferenceManager.getDefaultSharedPreferences(
            getApplicationContext()).getString("listLanguage", "en")
            .equals(langPreference))) {
        refresh();
    }
    super.onResume();
}

private void refresh() {
    finish();
    Intent myIntent = new Intent(Main.this, Main.class);
    startActivity(myIntent);
}

Dealing with a very lightweight embedded version of busybox on Linux means many of the traditional commands are not available (bc, printf, dc, perl, python)

echo $((0x2f))
47

hexNum=2f
echo $((0x${hexNum}))
47

Some example of code that I did for my project. Basically you add tags to your entity. Imagine you have input text, on entering Tag name you get drop-down menu with preloaded tags to choose from, you navigate with arrows and select with Enter:

HTML + AngularJS v1.2.0-rc.3

    <div>
        <form ng-submit="addTag(newTag)">
            <input id="newTag" ng-model="newTag" type="text" class="form-control" placeholder="Enter new tag"
                   style="padding-left: 10px; width: 700px; height: 33px; margin-top: 10px; margin-bottom: 3px;" autofocus
                   data-toggle="dropdown"
                   ng-change="preloadTags()"
                   ng-keydown="navigateTags($event)">
            <div ng-show="preloadedTags.length > 0">

In case of Excel 2007 You can change datasource in Options menu /Change Data Source

Try using "/" instead of "\" for the path to your image. Some comments here seem to come from people that do not understand some of us are simply learning web development which in many cases is best done locally. So instead of using src=C:\Pics\H.gif use src="C:/Pics/H.gif" for an absolute path or just src="Pics/H.gif" for a relative path if your Pics are in a sub-directory of your html page's location). Note also, it is good practice to surround your path with quotes. otherwise you will have problems with paths that include spaces and other odd characters.

Creating a sample file:

try {
    File file = new File ("c:/new-file.txt");
    if(file.createNewFile()) {
        System.out.println("Successful created!");
    }
    else {
        System.out.println("Failed to create!");
    }
}
catch (IOException e) {
    e.printStackTrace();
}

Your text may be located in the networking response.There is also a search tool in the Network tab, and you may try it.

What you want to search for may stay either in DOM or in memory. If it is not in DOM, well, it may be in memory, because you have just see it in your computer screen anyway. The text you search for may be loaded either from scripts in the initial DOM or from response in the later request.

When sending data to a web server, the data has to be a string (here). You can convert a JavaScript object into a string with JSON.stringify(). Here is a working example:

var fs = require('fs');

var originalNote = {
  title: 'Meeting',
  description: 'Meeting John Doe at 10:30 am'
};

var originalNoteString = JSON.stringify(originalNote);

fs.writeFileSync('notes.json', originalNoteString);

var noteString = fs.readFileSync('notes.json');

var note = JSON.parse(noteString);

console.log(`TITLE: ${note.title} DESCRIPTION: ${note.description}`);

Hope it could help.

Of course, be mindful that your program will only be useful in english speaking countries if you detect dates this way. You might want to consider:

Set<String> dayNames = Calendar.getInstance()
 .getDisplayNames(Calendar.DAY_OF_WEEK,
      Calendar.SHORT,
      Locale.getDefault())
 .keySet();

From there you can use .startsWith or .matches or whatever other method that others have mentioned above. This way you get the default locale for the jvm. You could always pass in the locale (and maybe default it to the system locale if it's null) as well to be more robust.

You can disable need to run Internet Explorer's first launch configuration by running this PowerShell script, it will adjust corresponding registry property:

Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Internet Explorer\Main" -Name "DisableFirstRunCustomize" -Value 2

After this, WebClient will work without problems

Well i also was in search of Associative array and found the List of maps as the best solution.

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;


public class testHashes {

public static void main(String args[]){
    Map<String,String> myMap1 = new HashMap<String, String>();

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

    myMap1.put("URL", "Val0");
    myMap1.put("CRC", "Vla1");
    myMap1.put("SIZE", "Vla2");
    myMap1.put("PROGRESS", "Vla2");

    myMap.add(0,myMap1);
    myMap.add(1,myMap1);

    for (Map<String, String> map : myMap) {
        System.out.println(map.get("URL"));
    }

    //System.out.println(myMap);

}


}

I came across this in PHP when using fopen() on a file and then trying to unlink() it before using fclose() on it.

No good:

$handle = fopen('file.txt');
// do something
unlink('file.txt');

Good:

$handle = fopen('file.txt');

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

Whatever approach you take, make sure in the end that you have an updated version of curl and libcurl. You can do curl --version and see the versions.

Here's what I did to get the latest curl version installed in Ubuntu:

1. sudo add-apt-repository "deb http://mirrors.kernel.org/ubuntu wily main"
2. sudo apt-get update
3. sudo apt-get install curl

Non-prototype version of toHHMMSS:

    function toHHMMSS(seconds) {
        var sec_num = parseInt(seconds);
        var hours   = Math.floor(sec_num / 3600);
        var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
        var seconds = sec_num - (hours * 3600) - (minutes * 60);        
        if (hours   < 10) {hours   = "0"+hours;}
        if (minutes < 10) {minutes = "0"+minutes;}
        if (seconds < 10) {seconds = "0"+seconds;}
        var time    = hours+':'+minutes+':'+seconds;
        return time;
    }   

May be too late to answer but you can multiple the output with 1 to convert to number again, here is an example.

const x1 = 1211.1212121;
const x2 = x1.toFixed(2)*1;
console.log(typeof(x2));

ls -t list files by creation time not last modified time. Use ls -ltc if you want to list files by last modified time from last to first(top to bottom). Thus to list the last n: ls -ltc | head ${n}

set TEXT_T="myfile.txt"
set /a c=1

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
    set /a c+=1
    set OUTPUT_FILE_NAME=output_%c%.txt
    echo Output file is %OUTPUT_FILE_NAME%
    echo %%i, %c%
)

For simple document, I sometimes use verbatim, but listing is nice for big chunk of code.

I ended up using GitKraken . I've installed, auth and connected to my repo in 30 seconds.

For Mac users, checkout (no pun intended) the free, open source tool GitUp: http://gitup.co/

I like the way the graphs are displayed, it's clearer than some of the other tools I've seen.

The project is here: https://github.com/git-up/GitUp

Was facing the same issue multiple times and I have 2 solutions:

Solution 1: Add surefire plugin reference to pom.xml. Watch that you have all nodes! In my IDEs auto import version was missing!!!

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>3.0.0-M3</version>
    </plugin>
</plugins>

Solution 2: My IDE added wrong import to the start of the file.

IDE added

import org.junit.Test;

I had to replace it with

import org.junit.jupiter.api.Test;

You can do:

User.find_or_create_by(first_name: 'Penélope', last_name: 'Lopez')
User.where(first_name: 'Penélope', last_name: 'Lopez').first_or_create

Or to just initialize:

User.find_or_initialize_by(first_name: 'Penélope', last_name: 'Lopez')
User.where(first_name: 'Penélope', last_name: 'Lopez').first_or_initialize

This is how I organized my application's static resources.

I've coded a simple function which allows to get the absolute location of the current javascript file, by using a try/catch method.

// Get script file location
// doesn't work for older browsers

var getScriptLocation = function() {
    var fileName    = "fileName";
    var stack       = "stack";
    var stackTrace  = "stacktrace";
    var loc     = null;

    var matcher = function(stack, matchedLoc) { return loc = matchedLoc; };

    try { 

        // Invalid code
        0();

    }  catch (ex) {

        if(fileName in ex) { // Firefox
            loc = ex[fileName];
        } else if(stackTrace in ex) { // Opera
            ex[stackTrace].replace(/called from line \d+, column \d+ in (.*):/gm, matcher);
        } else if(stack in ex) { // WebKit, Blink and IE10
            ex[stack].replace(/at.*?\(?(\S+):\d+:\d+\)?$/g, matcher);
        }

        return loc;
    }

};

I am using Anaconda-Jupyter Notebook on OS: Ubuntu 16.0 for Python programming.

Install Nbconvert, Pandoc, and Tex:

Open a terminal and implement the following commands in it.

Install Nbconvert: though it's part of the Jupyter ecosystem still install it once again

$conda install nbconvert

Or

$pip install nbconvert

But I will recommend using conda instead pip if you are using anaconda

Install Pandoc: since Nbconvert uses Pandoc for converting markdown to formats other than HTML. Type following command

$sudo apt-get install pandoc

Install TeX: For converting to PDF, nbconvert uses the TeX. Type following command

$sudo apt-get install texlive-xetex

After execution of these commands, close the opened notebooks refresh the home page Or restart the kernel of the opened notebook. Now try to download notebook as a pdf :)

Note: For more details, please refer the official documentation:
https://nbconvert.readthedocs.io/en/latest/install.html

Mongo lets you update nested documents using a . convention. Take a look: Updating nested documents in mongodb. Here's another question from the past about a merge update, like the one you're looking for I believe: MongoDB atomic update via 'merge' document

I agree with what @fge said, more over. Lets look at example. Consider you have a method:

class A {
    public void foo(OtherClass other) {
        SomeData data = new SomeData("Some inner data");
        other.doSomething(data);
    }
}

Now if you want to check the inner data you can use the captor:

// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);

// Run the foo method with the mock
new A().foo(other);

// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());

// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);

I think you are asking about code like this.

int  count = (request.getParameter("counter") == null) ? 0 : Integer.parseInt(request.getParameter("counter"));

If the above solution does not work for you, try this:

#1.1 Do NOT ignore file pattern in  any subdirectory
!*/config.php
#1.2 ...only ignore it in the current directory
/config.php

##########################

# 2.1 Ignore file pattern everywhere
config.php
# 2.2 ...but NOT in the current directory
!/config.php

Enable intercepter in this way

Basically it is a chrome plug in. After installing the extention, you also need to make sure the extention is enabled from chrome side.

You can implement this way

$resource('http://localhost\\:3000/realmen/:entryId', {entryId: '@entryId'}, {
        UPDATE: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId' },
        ACTION: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId/action' }
    })

RealMen.query() //GET  /realmen/
RealMen.save({entryId: 1},{post data}) // POST /realmen/1
RealMen.delete({entryId: 1}) //DELETE /realmen/1

//any optional method
RealMen.UPDATE({entryId:1}, {post data}) // PUT /realmen/1

//query string
RealMen.query({name:'john'}) //GET /realmen?name=john

Hope it helps

This may be OLD, but here is the best answer:

    float dist = (float) Math.sqrt(
            Math.pow(x1 - x2, 2) +
            Math.pow(y1 - y2, 2) );

You can put the following code on the default value of the timestamp column: CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, so on update the two columns take the same value.

My solution in plain js:

let el=document.getElementById('el');_x000D_
el.addEventListener('scroll', function(e) {_x000D_
    if (this.scrollHeight - this.scrollTop - this.clientHeight<=0) {_x000D_
        alert('Bottom');_x000D_
    }_x000D_
});

#el{_x000D_
  width:400px;_x000D_
  height:100px;_x000D_
  overflow-y:scroll;_x000D_
}

<div id="el">_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
<div>content</div>_x000D_
</div>

This is the shortest way I've found (needs jQuery1.6+)

HTML:

<input type="checkbox" id="checkAll"/>

JS:

$("#checkAll").change(function () {
    $("input:checkbox").prop('checked', $(this).prop("checked"));
});

I'm using .prop as .attr doesn't work for checkboxes in jQuery 1.6+ unless you've explicitly added a checked attribute to your input tag.

Example-

$("#checkAll").change(function () {_x000D_
    $("input:checkbox").prop('checked', $(this).prop("checked"));_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<form action="#">_x000D_
    <p><label><input type="checkbox" id="checkAll"/> Check all</label></p>_x000D_
    _x000D_
    <fieldset>_x000D_
        <legend>Loads of checkboxes</legend>_x000D_
        <p><label><input type="checkbox" /> Option 1</label></p>_x000D_
        <p><label><input type="checkbox" /> Option 2</label></p>_x000D_
        <p><label><input type="checkbox" /> Option 3</label></p>_x000D_
        <p><label><input type="checkbox" /> Option 4</label></p>_x000D_
    </fieldset>_x000D_
</form>

I know this is an old question, but I have yet another alternative solution with jQuery:

var actionForm = $('<form>', {'action': 'nextpage.php', 'method': 'post'}).append($('<input>', {'name': 'action', 'value': 'delete', 'type': 'hidden'}), $('<input>', {'name': 'id', 'value': 'some_id', 'type': 'hidden'}));
actionForm.submit();

The above code uses jQuery to create a form tag, appending hidden fields as post fields, and submit it at last. The page will forward to the form target page with the POST data attached.

p.s. JavaScript & jQuery are required for this case. As suggested by the comments of the other answers, you can make use of <noscript> tag to create a standard HTML form in case JS is disabled.

Another way is call super() with the required argument as a first statement in derived class constructor.

public class Sup {
    public Sup(String s) { ...}
}

public class Sub extends Sup {
    public Sub() { super("hello"); .. }
}

In my experience, MyISAM was a better choice as long as you don't do DELETEs, UPDATEs, a whole lot of single INSERT, transactions, and full-text indexing. BTW, CHECK TABLE is horrible. As the table gets older in terms of the number of rows, you don't know when it will end.

There is no need to use substr method to get a single char of a string!

taking the example of Jamon Holmgren we can change substr method and simply specify the array position:

var id = "ctl03_Tabs1";
var lastChar = id[id.length - 1]; // => "1"
