I found this worked for me.

$username = 'user'
$password = 'password'

$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword
Start-Process Notepad.exe -Credential $credential

Updated: changed to using single quotes to avoid special character issues noted by Paddy.

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml

You need to run Set-ExecutionPolicy:

Set-ExecutionPolicy Unrestricted <-- Will allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy Restricted <-- Will not allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy RemoteSigned <-- Will allow only remotely signed PowerShell scripts to run.

Aha. This turned out to be a simple problem of there being spaces in the path to the script.

Changing the Invoke-Expression line to:

Invoke-Expression "& `"$scriptPath`" $argumentList"

...was enough to get it to kick off. Thanks to Neolisk for your help and feedback!

As short as @jumbo's answer is :-) you can do it even more tersely. This just returns the Count property of the array returned by the antecedent sub-expression:

@(Get-Alias).Count

A couple points to note:

1. You can put an arbitrarily complex expression in place of Get-Alias, for example:

   @(Get-Process | ? { $_.ProcessName -eq "svchost" }).Count
   

2. The initial at-sign (@) is necessary for a robust solution. As long as the answer is two or greater you will get an equivalent answer with or without the @, but when the answer is zero or one you will get no output unless you have the @ sign! (It forces the Count property to exist by forcing the output to be an array.)

2012.01.30 Update

The above is true for PowerShell V2. One of the new features of PowerShell V3 is that you do have a Count property even for singletons, so the at-sign becomes unimportant for this scenario.

Luke's description of the function results in these scenarios seems to be right on. I only wish to understand the root cause and the PowerShell product team would do something about the behavior. It seems to be quite common and has cost me too much debugging time.

To get around this issue I've been using global variables rather than returning and using the value from the function call.

Here's another question on the use of global variables: Setting a global PowerShell variable from a function where the global variable name is a variable passed to the function

Select-Object returns a custom PSObject with just the properties specified. Even with a single property, you don't get the ACTUAL variable; it is wrapped inside the PSObject.

Instead, do:

Get-Date | Select-Object -ExpandProperty DayOfWeek

That will get you the same result as:

(Get-Date).DayOfWeek

The difference is that if Get-Date returns multiple objects, the pipeline way works better than the parenthetical way as (Get-ChildItem), for example, is an array of items. This has changed in PowerShell v3 and (Get-ChildItem).FullPath works as expected and returns an array of just the full paths.

-ErrorAction Stop is changing things for you. Try adding this and see what you get:

Catch [System.Management.Automation.ActionPreferenceStopException] {
"caught a StopExecution Exception" 
$error[0]
}

The assembly coming with Powershell SDK (C:\Program Files\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0) does not come with Powershell 2 specific types.

Manually editing the csproj file solved my problem.

The expression a == b should do the job.

I tried use [disabled]="!editmode" but it not work in my case.

This is my solution [disabled]="!editmode ? 'disabled': null" , I share for whom concern.

<button [disabled]="!editmode ? 'disabled': null" 
    (click)='loadChart()'>
            <div class="btn-primary">Load Chart</div>
    </button>

Unfortunately, the

(falseValue, trueValue)[test]

solution doesn't have short-circuit behaviour; thus both falseValue and trueValue are evaluated regardless of the condition. This could be suboptimal or even buggy (i.e. both trueValue and falseValue could be methods and have side-effects).

One solution to this would be

(lambda: falseValue, lambda: trueValue)[test]()

(execution delayed until the winner is known ;)), but it introduces inconsistency between callable and non-callable objects. In addition, it doesn't solve the case when using properties.

And so the story goes - choosing between 3 mentioned solutions is a trade-off between having the short-circuit feature, using at least ?ython 2.5 (IMHO not a problem anymore) and not being prone to "trueValue-evaluates-to-false" errors.

This is one way to do it:

Fiddle here: http://jsfiddle.net/4Mvan/1/

HTML:

<div class='container'>
    <a href='#'>
    <img class='resize_fit_center'
      src='http://i.imgur.com/H9lpVkZ.jpg' />
    </a>
</div>

CSS:

.container {
    margin: 10px;
    width: 115px;
    height: 115px;
    line-height: 115px;
    text-align: center;
    border: 1px solid red;
}
.resize_fit_center {
    max-width:100%;
    max-height:100%;
    vertical-align: middle;
}

You can use instanceof.

JLS 15.20.2 Type Comparison Operator instanceof

 RelationalExpression:
    RelationalExpression instanceof ReferenceType

At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a ClassCastException. Otherwise the result is false.

That means you can do something like this:

Object o = new int[] { 1,2 };
System.out.println(o instanceof int[]); // prints "true"        

You'd have to check if the object is an instanceof boolean[], byte[], short[], char[], int[], long[], float[], double[], or Object[], if you want to detect all array types.

Also, an int[][] is an instanceof Object[], so depending on how you want to handle nested arrays, it can get complicated.

For the toString, java.util.Arrays has a toString(int[]) and other overloads you can use. It also has deepToString(Object[]) for nested arrays.

public String toString(Object arr) {
   if (arr instanceof int[]) {
      return Arrays.toString((int[]) arr);
   } else //...
}

It's going to be very repetitive (but even java.util.Arrays is very repetitive), but that's the way it is in Java with arrays.

You can do:

$ pip install "package>=0.2,<0.3"

And pip will look for the best match, assuming the version is at least 0.2, and less than 0.3.

This also applies to pip requirements files. See the full details on version specifiers in PEP 440.

I also wrote a combination of Mockito and AspectJ: https://github.com/iirekm/varia/tree/develop/ajmock

Your example becomes:

when(() -> DriverManager.getConnection(...)).thenReturn(...);

Place this at the top of your script. It will cause the script to prompt the user for a password. The resulting password can then be used elsewhere in your script via $pw.

   Param(
     [Parameter(Mandatory=$true, Position=0, HelpMessage="Password?")]
     [SecureString]$password
   )

   $pw = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($password))

If you want to debug and see the value of the password you just read, use:

   write-host $pw

Here's how I do this (it might not be optimal, but it works):

Create the div that you want to be semi-transparent. Give it a class/id. Leave it empty, and close it. Give it a set height and width (say, 300 pixels by 300 pixels). Give it an opacity of 0.5 or whatever you like, and a background color.

Then, directly below that div, create another div with a different class/id. Create a paragraph inside it, where you'll place your text. Give the div position: relative, and top: -295px (that's negative 295 pixels). Give it a z-index of 2 for good measure, and make sure its opacity is 1. Style your paragraph as you like, but make sure the dimensions are less than that of the first div so it doesn't overflow.

That's it. Here's the code:

.trans {_x000D_
  opacity: 0.5;_x000D_
  height: 300px;_x000D_
  width: 300px;_x000D_
  background-color: orange;_x000D_
}_x000D_
.trans2 {_x000D_
  opacity: 1;_x000D_
  position: relative;_x000D_
  top: -295px;_x000D_
}_x000D_
.trans2 p {_x000D_
  width: 295px;_x000D_
  color: black;_x000D_
  font-weight: bold;_x000D_
}

<body>_x000D_
  <div class="trans">_x000D_
  </div>_x000D_
  <div class="trans2">_x000D_
    <p>_x000D_
      text text text_x000D_
    </p>_x000D_
  </div>_x000D_
</body>

This works in Safari 2.x, but I don't know about Internet Explorer.

For GCC, this is accomplished in two stages:

First compile the data but tell the compiler to separate the code into separate sections within the translation unit. This will be done for functions, classes, and external variables by using the following two compiler flags:

-fdata-sections -ffunction-sections

Link the translation units together using the linker optimization flag (this causes the linker to discard unreferenced sections):

-Wl,--gc-sections

So if you had one file called test.cpp that had two functions declared in it, but one of them was unused, you could omit the unused one with the following command to gcc(g++):

gcc -Os -fdata-sections -ffunction-sections test.cpp -o test -Wl,--gc-sections

(Note that -Os is an additional compiler flag that tells GCC to optimize for size)

See the following project on GitHub: https://github.com/ghuntley/csharp-mssql-connectivity-tester

try
{
    Console.WriteLine("Connecting to: {0}", AppConfig.ConnectionString);
    using (var connection = new SqlConnection(AppConfig.ConnectionString))
    {
        var query = "select 1";
        Console.WriteLine("Executing: {0}", query);

        var command = new SqlCommand(query, connection);

        connection.Open();
        Console.WriteLine("SQL Connection successful.");

        command.ExecuteScalar();
        Console.WriteLine("SQL Query execution successful.");
    }
}
catch (Exception ex)
{
    Console.WriteLine("Failure: {0}", ex.Message);
}

If you are a developer, this is what you need to do:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />

Use This..... You will love it

 <TextView
    android:layout_width="fill_parent"
    android:layout_height="1px"
    android:text=" "
    android:background="#anycolor"
    android:id="@+id/textView"/>

This can also be achieved with a more native HTML solution by using the output element.

<form oninput="result.value=parseInt(a.valueAsNumber)+parseInt(b.valueAsNumber)">
  <input type="number" id="a" name="a" value="10" /> +
  <input type="number" id="b" name="b" value="50" /> =
  <output name="result" for="a b">60</output>
</form>

https://jsfiddle.net/gxu1rtqL/

The output element can serve as a container element for a calculation or output of a user's action. You can also change the HTML type from number to range and keep the same code and functionality with a different UI element, as shown below.

<form oninput="result.value=parseInt(a.valueAsNumber)+parseInt(b.valueAsNumber)">
  <input type="range" id="a" name="a" value="10" /> +
  <input type="number" id="b" name="b" value="50" /> =
  <output name="result" for="a b">60</output>
</form>

I'm the creator of Restangular.

You can take a look at this CRUD example to see how you can PUT/POST/GET elements without all that URL configuration and $resource configuration that you need to do. Besides it, you can then use nested resources without any configuration :).

Check out this plunkr example:

http://plnkr.co/edit/d6yDka?p=preview

You could also see the README and check the documentation here https://github.com/mgonto/restangular

If you need some feature that's not there, just create an issue. I usually add features asked within a week, as I also use this library for all my AngularJS projects :)

Hope it helps!

There's yet another way to do it using Shared Connections, ie: somebody initiates the connection, using a password, and every subsequent connection will multiplex over the same channel, negating the need for re-authentication. ( And its faster too )

# ~/.ssh/config 
ControlMaster auto
ControlPath ~/.ssh/pool/%r@%h

then you just have to log in, and as long as you are logged in, the bash script will be able to open ssh connections.

You can then stop your script from working when somebody has not already opened the channel by:

ssh ... -o KbdInteractiveAuthentication=no ....

nuget restore 

and

msbuild /t:restore

both didn't work for me with same error. But

dotnet restore 

worked perfect. Try that

Easiest way to check if a string is a date:

if(strtotime($date_string)){
    // it's in date format
}

Replace '\n' with "\n". The escape sequence is not recognized when you use '.

See the manual.

For the question of how to write line endings, see the note here. Basically, different operating systems have different conventions for line endings. Windows uses "\r\n", unix based operating systems use "\n". You should stick to one convention (I'd chose "\n") and open your file in binary mode (fopen should get "wb", not "w").

If you're using CLI and you're a postgres user, then you can do this:

psql -c "SELECT version();"

Possible output:

Use the accept attribute of the input tag. So to accept only PNG's, JPEG's and GIF's you can use the following code:

<input type="file" name="myImage" accept="image/x-png,image/gif,image/jpeg" />

Or simply:

<input type="file" name="myImage" accept="image/*" />

Note that this only provides a hint to the browser as to what file-types to display to the user, but this can be easily circumvented, so you should always validate the uploaded file on the server also.

It should work in IE 10+, Chrome, Firefox, Safari 6+, Opera 15+, but support is very sketchy on mobiles (as of 2015) and by some reports, this may actually prevent some mobile browsers from uploading anything at all, so be sure to test your target platforms well.

For detailed browser support, see http://caniuse.com/#feat=input-file-accept

There is no such thing in python like forward declaration. You just have to make sure that your function is declared before it is needed. Note that the body of a function isn't interpreted until the function is executed.

Consider the following example:

def a():
   b() # won't be resolved until a is invoked.

def b(): 
   print "hello"

a() # here b is already defined so this line won't fail.

You can think that a body of a function is just another script that will be interpreted once you call the function.

As Uriel says, it is meant for a method in an abstract class that should be implemented in child class, but can be used to indicate a TODO as well.

There is an alternative for the first use case: Abstract Base Classes. Those help creating abstract classes.

Here's a Python 3 example:

class C(abc.ABC):
    @abc.abstractmethod
    def my_abstract_method(self, ...):
        ...

When instantiating C, you'll get an error because my_abstract_method is abstract. You need to implement it in a child class.

TypeError: Can't instantiate abstract class C with abstract methods my_abstract_method

Subclass C and implement my_abstract_method.

class D(C):
    def my_abstract_method(self, ...):
        ...

Now you can instantiate D.

C.my_abstract_method does not have to be empty. It can be called from D using super().

An advantage of this over NotImplementedError is that you get an explicit Exception at instantiation time, not at method call time.

The CSS standard enables some advanced formatting. There is a @page directive in CSS that enables some formatting that applies only to paged media (like paper). See http://www.w3.org/TR/1998/REC-CSS2-19980512/page.html.

and for firefox use it

In Firefox, https://bug743252.bugzilla.mozilla.org/attachment.cgi?id=714383 (view page source :: tag HTML).

In your code, replace <html> with <html moznomarginboxes mozdisallowselectionprint>.

Check out this article and this simple example. Quick translation of same to your classes ...

var d1 = typeof(Task<>);
Type[] typeArgs = { typeof(Item) };
var makeme = d1.MakeGenericType(typeArgs);
object o = Activator.CreateInstance(makeme);

Per your edit: For that case, you can do this ...

var d1 = Type.GetType("GenericTest.TaskA`1"); // GenericTest was my namespace, add yours
Type[] typeArgs = { typeof(Item) };
var makeme = d1.MakeGenericType(typeArgs);
object o = Activator.CreateInstance(makeme);

To see where I came up with backtick1 for the name of the generic class, see this article.

Note: if your generic class accepts multiple types, you must include the commas when you omit the type names, for example:

Type type = typeof(IReadOnlyDictionary<,>);

When i analyzed your code. I have also faced the same problem but my problem is if i give value for both first and last name means it is working fine. but when i give only one value means it says 400. anyway use the .andDo(print()) method to find out the error

public void testGetUserByName() throws Exception {
    String firstName = "Jack";
    String lastName = "s";       
    this.userClientObject = client.createClient();
    mockMvc.perform(get("/byName")
            .sessionAttr("userClientObject", this.userClientObject)
            .param("firstName", firstName)
            .param("lastName", lastName)               
    ).andDo(print())
     .andExpect(status().isOk())
            .andExpect(content().contentType("application/json"))
            .andExpect(jsonPath("$[0].id").exists())
            .andExpect(jsonPath("$[0].fn").value("Marge"));
}

If your problem is org.springframework.web.bind.missingservletrequestparameterexception you have to change your code to

@RequestMapping(value = "/byName", method = RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public
    @ResponseBody
    String getUserByName(
        @RequestParam( value="firstName",required = false) String firstName,
        @RequestParam(value="lastName",required = false) String lastName, 
        @ModelAttribute("userClientObject") UserClient userClient)
    {

        return client.getUserByName(userClient, firstName, lastName);
    }

Only for IE Browser:

var ie = 'NotIE'; //IE5-11, Edge+
    if( !!document.compatMode ) {
        if( !("ActiveXObject" in window) ) ) ie = 'EDGE';
        if( !!document.uniqueID){
            if('ActiveXObject' in window && !window.createPopup ){ ie = 11; }
            else if(!!document.all){
                    if(!!window.atob){ie = 10;}
                    else if(!!document.addEventListener) {ie = 9;}
                    else if(!!document.querySelector){ie = 8;}
                    else if(!!window.XMLHttpRequest){ie = 7;}
                    else if(!!document.compatMode){ie = 6;}
                    else ie = 5;

Update 01 Jun 2017

Now we could use something easier and simpler:

var uA = window.navigator.userAgent,
    onlyIEorEdge = /msie\s|trident\/|edge\//i.test(uA) && !!( document.uniqueID || window.MSInputMethodContext),
    checkVersion = (onlyIEorEdge && +(/(edge\/|rv:|msie\s)([\d.]+)/i.exec(uA)[2])) || NaN;

if your using php for the backend maybe you can use this code.

// Validate image file size
if (($_FILES["file-input"]["size"] > 2000000)) {
    $msg = "Image File Size is Greater than 2MB.";
    header("Location: ../product.php?error=$msg");
    exit();
}  

I use static fields in a class, and get/set them:

Like:

public class Info
{
    public static int ID      = 0;
    public static String NAME = "TEST";
}

For getting a value, use this in an Activity:

Info.ID
Info.NAME

For setting a value:

Info.ID = 5;
Info.NAME = "USER!";

I have seen comments in INI files, so yes. Please refer to this Wikipedia article. I could not find an official specification, but that is the correct syntax for comments, as many game INI files had this as I remember.

Edit

The API returns the Value and the Comment (forgot to mention this in my reply), just construct and example INI file and call the API on this (with comments) and you can see how this is returned.

here's another way of making a draggable object that is centered to the click

http://jsfiddle.net/pixelass/fDcZS/

function endMove() {
    $(this).removeClass('movable');
}

function startMove() {
    $('.movable').on('mousemove', function(event) {
        var thisX = event.pageX - $(this).width() / 2,
            thisY = event.pageY - $(this).height() / 2;

        $('.movable').offset({
            left: thisX,
            top: thisY
        });
    });
}
$(document).ready(function() {
    $("#containerDiv").on('mousedown', function() {
        $(this).addClass('movable');
        startMove();
    }).on('mouseup', function() {
        $(this).removeClass('movable');
        endMove();
    });

});

CSS

#containerDiv {
    background:#333;
    position:absolute;
    width:200px;
    height:100px;
}

<?php 
  ${test}="test information";
  echo $test;
?>

Notice: Use of undefined constant test - assumed 'test' in D:\xampp\htdocs\sp\test\envoirnmentVariables.php on line 3 test information

take a look at xp_sprintf. example below.

DECLARE @ret_string varchar (255)
EXEC xp_sprintf @ret_string OUTPUT, 
    'INSERT INTO %s VALUES (%s, %s)', 'table1', '1', '2'
PRINT @ret_string

Result looks like this:

INSERT INTO table1 VALUES (1, 2)

Just found an issue with the max size (255 char limit) of the string with this so there is an alternative function you can use:

create function dbo.fnSprintf (@s varchar(MAX), 
                @params varchar(MAX), @separator char(1) = ',')
returns varchar(MAX)
as
begin
declare @p varchar(MAX)
declare @paramlen int

set @params = @params + @separator
set @paramlen = len(@params)
while not @params = ''
begin
    set @p = left(@params+@separator, charindex(@separator, @params)-1)
    set @s = STUFF(@s, charindex('%s', @s), 2, @p)
    set @params = substring(@params, len(@p)+2, @paramlen)
end
return @s
end

To get the same result as above you call the function as follows:

print dbo.fnSprintf('INSERT INTO %s VALUES (%s, %s)', 'table1,1,2', default)

You could use the new Python 3.4 library pathlib. (You can also get it for Python 2.6 or 2.7 using pip install pathlib.) The authors wrote: "The aim of this library is to provide a simple hierarchy of classes to handle filesystem paths and the common operations users do over them."

To get an absolute path in Windows:

>>> from pathlib import Path
>>> p = Path("pythonw.exe").resolve()
>>> p
WindowsPath('C:/Python27/pythonw.exe')
>>> str(p)
'C:\\Python27\\pythonw.exe'

Or on UNIX:

>>> from pathlib import Path
>>> p = Path("python3.4").resolve()
>>> p
PosixPath('/opt/python3/bin/python3.4')
>>> str(p)
'/opt/python3/bin/python3.4'

Docs are here: https://docs.python.org/3/library/pathlib.html

If you need an ordered dictionary, you can use odict.

If you just want your query data dumped into excel I have to do this frequently and using an html table is a very simple method. I use mysqli for db queries and the following code for exports to excel:

header("Content-Type: application/xls");    
header("Content-Disposition: attachment; filename=filename.xls");  
header("Pragma: no-cache"); 
header("Expires: 0");


echo '<table border="1">';
//make the column headers what you want in whatever order you want
echo '<tr><th>Field Name 1</th><th>Field Name 2</th><th>Field Name 3</th></tr>';
//loop the query data to the table in same order as the headers
while ($row = mysqli_fetch_assoc($result)){
    echo "<tr><td>".$row['field1']."</td><td>".$row['field2']."</td><td>".$row['field3']."</td></tr>";
}
echo '</table>';

Title_Authors is a look up two things join at a time project results and continue chaining

        DataClasses1DataContext db = new DataClasses1DataContext();
        var queryresults = from a in db.Authors                                          
                    join ba in db.Title_Authors                           
                    on a.Au_ID equals ba.Au_ID into idAuthor
                    from c in idAuthor
                    join t in db.Titles  
                    on c.ISBN equals t.ISBN 
                    select new { Author = a.Author1,Title= t.Title1 };

        foreach (var item in queryresults)
        {
            MessageBox.Show(item.Author);
            MessageBox.Show(item.Title);
            return;
        }

Controller

 $campaignStatus = Campaign::lists('status', 'id');

compact('campaignStatus') will result in [id=>status]; //example [1 => 'pending']

return view('management.campaign.index', compact('campaignStatus'));

View

{!! Form::select('status', $campaignStatus, array('class' => 'form-control')) !!}

The padding inside a table-divider (TD) is a padding property applied to the cell itself.

CSS

td, th {padding:0}

The spacing in-between the table-dividers is a space between cell borders of the TABLE. To make it effective, you have to specify if your table cells borders will 'collapse' or be 'separated'.

CSS

table, td, th {border-collapse:separate}
table {border-spacing:6px}

Try this : https://www.google.ca/search?num=100&newwindow=1&q=css+table+cellspacing+cellpadding+site%3Astackoverflow.com ( 27 100 results )

You certainly can define functions in script files (I then tend to load them through my Powershell profile on load).

First you need to check to make sure the function is loaded by running:

ls function:\ | where { $_.Name -eq "A1"  }

And check that it appears in the list (should be a list of 1!), then let us know what output you get!

NSString objects are immutable (they can't be changed), but there is a mutable subclass, NSMutableString, that gives you several methods for replacing characters within a string. It's probably your best bet.

Using ' and " at the same time works great for me (Windows 10, python 3)

import os
os.system('"some cmd command here"')

for example to open my web browser I can use this:

os.system('"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"')

(Edit) for an easier way to open your browser I can use this:

import webbrowser
webbrowser.open('website or leave it alone if you only want to open the 
browser')

Inverse and default class name mention in Twitter Bootstrap cause them to be black and white color.

Better, you should not override that and add a class near that and write you particular style for that:

my_style{_x000D_
    background-color: green;_x000D_
}

This is an error caused by importing the wrong module react from 'react' how about you try this: 1st

import React , { Component}  from 'react';

2nd Or you can try this as well:

import React from 'react';
import { render   }  from 'react-dom';

class TechView extends React.Component {

    constructor(props){
       super(props);
       this.state = {
           name:'Gopinath',
       }
    }
    render(){
        return(
            <span>hello Tech View</span>
        );
    }
}

export default TechView;

You can easily do it after use array_values() and array_filter() function together to remove empty array elements and reindex from an array in PHP.

array_filter() function The PHP array_filter() function remove empty array elements or values from an array in PHP. This will also remove blank, null, false, 0 (zero) values.

array_values() function The PHP array_values() function returns an array containing all the values of an array. The returned array will have numeric keys, starting at 0 and increase by 1.

Remove Empty Array Elements and Reindex

First let’s see the $stack array output :

<?php
  $stack = array("PHP", "HTML", "CSS", "", "JavaScript", null, 0);
  print_r($stack);
?>

Output:

Array
(
    [0] => PHP
    [1] => HTML
    [2] => CSS
    [3] => 
    [4] => JavaScript
    [5] => 
    [6] => 0
)

In above output we want to remove blank, null, 0 (zero) values and then reindex array elements. Now we will use array_values() and array_filter() function together like in below example:

<?php
  $stack = array("PHP", "HTML", "CSS", "", "JavaScript", null, 0);
  print_r(array_values(array_filter($stack)));
?>

Output:

Array
(
    [0] => PHP
    [1] => HTML
    [2] => CSS
    [3] => JavaScript
)

I use to use the Do, Loop a lot but I have started using a Sub or a Function that I could exit out of instead. It just seemed cleaner to me. If any variables you need are not global you will need to pass them to the Sub also.

For i=1 to N
 DoWork i
Next

Sub DoWork(i)
    [Code]
    If Condition1 Then
      Exit Sub
    End If

    [MoreCode]
    If Condition2 Then
      Exit Sub
    End If

    [MoreCode]
    If Condition2 Then
      Exit Sub
    End If

    [...]
End Sub

If you check out the help of the unittest module it tells you about several combinations that allow you to run test case classes from a module and test methods from a test case class.

python3 -m unittest -h

[...]

Examples:
  python3 -m unittest test_module               - run tests from test_module
  python3 -m unittest module.TestClass          - run tests from module.TestClass
  python3 -m unittest module.Class.test_method  - run specified test method
```lang-none

It does not require you to define a `unittest.main()` as the default behaviour of your module.

I had similar question however mine involved a column Convert(date,mydatetime). I had to alter the best answer as follows:

Select
     count(created_date) as counted_leads,
     Convert(date,created_date) as count_date 
from table
group by Convert(date,created_date)

The title for the actionbar could be in the AndroidManifest, here:

<activity 
    . . .
          android:label="string resource" 
    . . .
</activity>

android:label A user-readable label for the activity. The label is displayed on-screen when the activity must be represented to the user. It's often displayed along with the activity icon. If this attribute is not set, the label set for the application as a whole is used instead (see the element's label attribute). The activity's label — whether set here or by the element — is also the default label for all the activity's intent filters (see the element's label attribute). The label should be set as a reference to a string resource, so that it can be localized like other strings in the user interface. However, as a convenience while you're developing the application, it can also be set as a raw string.

You can use QPalette, however you must set setAutoFillBackground(true); to enable background color

QPalette sample_palette;
sample_palette.setColor(QPalette::Window, Qt::white);
sample_palette.setColor(QPalette::WindowText, Qt::blue);

sample_label->setAutoFillBackground(true);
sample_label->setPalette(sample_palette);
sample_label->setText("What ever text");

It works fine on Windows and Ubuntu, I haven't played with any other OS.

Note: Please see QPalette, color role section for more details

Check this link , and last comment , You have to use WebChromeClient for your purpose.

I haven't ever seen such a thing, but there is this dev tool that includes a syntax checker for oracle, mysql, db2, and sql server... http://www.sqlparser.com/index.php

However this seems to be just the library. You'd need to build an app to leverage the parser to do what you want. And the Enterprise edition that includes all of the databases would cost you $450... ouch!

EDIT: And, after saying that - it looks like someone might already have done what you want using that library: http://www.wangz.net/cgi-bin/pp/gsqlparser/sqlpp/sqlformat.tpl

The online tool doesn't automatically check against each DB though, you need to run each manually. Nor can I say how good it is at checking the syntax. That you'd need to investigate yourself.

I thought up a rather elegant solution (IMHO), so I can't resist posting it:

from bisect import bisect_left

class Interpolate(object):
    def __init__(self, x_list, y_list):
        if any(y - x <= 0 for x, y in zip(x_list, x_list[1:])):
            raise ValueError("x_list must be in strictly ascending order!")
        x_list = self.x_list = map(float, x_list)
        y_list = self.y_list = map(float, y_list)
        intervals = zip(x_list, x_list[1:], y_list, y_list[1:])
        self.slopes = [(y2 - y1)/(x2 - x1) for x1, x2, y1, y2 in intervals]

    def __getitem__(self, x):
        i = bisect_left(self.x_list, x) - 1
        return self.y_list[i] + self.slopes[i] * (x - self.x_list[i])

I map to float so that integer division (python <= 2.7) won't kick in and ruin things if x1, x2, y1 and y2 are all integers for some iterval.

In __getitem__ I'm taking advantage of the fact that self.x_list is sorted in ascending order by using bisect_left to (very) quickly find the index of the largest element smaller than x in self.x_list.

Use the class like this:

i = Interpolate([1, 2.5, 3.4, 5.8, 6], [2, 4, 5.8, 4.3, 4])
# Get the interpolated value at x = 4:
y = i[4]

I've not dealt with the border conditions at all here, for simplicity. As it is, i[x] for x < 1 will work as if the line from (2.5, 4) to (1, 2) had been extended to minus infinity, while i[x] for x == 1 or x > 6 will raise an IndexError. Better would be to raise an IndexError in all cases, but this is left as an exercise for the reader. :)

Here is the plunker

New plunker with cleaner code & where both the query and search list items are case insensitive

Main idea is create a filter function to achieve this purpose.

From official doc

function: A predicate function can be used to write arbitrary filters. The function is called for each element of array. The final result is an array of those elements that the predicate returned true for.

<input ng-model="query">

<tr ng-repeat="smartphone in smartphones | filter: search "> 

$scope.search = function(item) {
    if (!$scope.query || (item.brand.toLowerCase().indexOf($scope.query) != -1) || (item.model.toLowerCase().indexOf($scope.query.toLowerCase()) != -1) ){
        return true;
    }
    return false;
};

Update

Some people might have a concern on performance in real world, which is correct.

In real world, we probably would do this kinda filter from controller.

Here is the detail post showing how to do it.

in short, we add ng-change to input for monitoring new search change

and then trigger filter function.

App Engine is a Platform-as-a-Service. It means that you simply deploy your code, and the platform does everything else for you. For example, if your app becomes very successful, App Engine will automatically create more instances to handle the increased volume.

Read more about App Engine

Compute Engine is an Infrastructure-as-a-Service. You have to create and configure your own virtual machine instances. It gives you more flexibility and generally costs much less than App Engine. The drawback is that you have to manage your app and virtual machines yourself.

Read more about Compute Engine

You can mix both App Engine and Compute Engine, if necessary. They both work well with the other parts of the Google Cloud Platform.

EDIT (May 2016):

One more important distinction: projects running on App Engine can scale down to zero instances if no requests are coming in. This is extremely useful at the development stage as you can go for weeks without going over the generous free quota of instance-hours. Flexible runtime (i.e. "managed VMs") require at least one instance to run constantly.

EDIT (April 2017):

Cloud Functions (currently in beta) is the next level up from App Engine in terms of abstraction - no instances! It allows developers to deploy bite-size pieces of code that execute in response to different events, which may include HTTP requests, changes in Cloud Storage, etc.

The biggest difference with App Engine is that functions are priced per 100 milliseconds, while App Engine's instances shut down only after 15 minutes of inactivity. Another advantage is that Cloud Functions execute immediately, while a call to App Engine may require a new instance - and cold-starting a new instance may take a few seconds or longer (depending on runtime and your code).

This makes Cloud Functions ideal for (a) rare calls - no need to keep an instance live just in case something happens, (b) rapidly changing loads where instances are often spinning and shutting down, and possibly more use cases.

FILE *file;
    if((file = fopen("sample.txt","r"))!=NULL)
        {
            // file exists
            fclose(file);
        }
    else
        {
            //File not found, no memory leak since 'file' == NULL
            //fclose(file) would cause an error
        }

It depends on the context.

When it's within a class:

class example1 {

    int a = 10; // This is package-private (visible within package)

    void method1() // This is package-private as well.
    {
        -----
    }
}

When it's within a interface:

interface example2 {

    int b = 10; // This is public and static.
    void method2(); // This is public and abstract
}

It is not natively possible to run Android application under iOS (which powers iPhone, iPad, iPod, etc.)

This is because both runtime stacks use entirely different approaches. Android runs Dalvik (a "variant of Java") bytecode packaged in APK files while iOS runs Compiled (from Obj-C) code from IPA files. Excepting time/effort/money and litigations (!), there is nothing inherently preventing an Android implementation on Apple hardware, however.

It looks to package a small Dalvik VM with each application and targeted towards developers.

See iPhoDroid:

Looks to be a dual-boot solution for 2G/3G jailbroken devices. Very little information available, but there are some YouTube videos.

See iAndroid:

iAndroid is a new iOS application for jailbroken devices that simulates the Android operating system experience on the iPhone or iPod touch. While it’s still very far from completion, the project is taking shape.

I am not sure the approach(es) it uses to enable this: it could be emulation or just a simulation (e.g. "looks like"). The requirement of being jailbroken makes it sound like emulation might be used ..

See BlueStacks, per the Holo Dev's comment:

It looks to be an "Android App Player" for OS X (and Windows). However, afaik, it does not [currently] target iOS devices ..

YMMV

There's a hotbackup.py script available on the Subversion web site that's quite handy for automating backups.

http://svn.apache.org/repos/asf/subversion/trunk/tools/backup/hot-backup.py.in

I think you want to cast your dt to a date and fix the format of your date literal:

SELECT *
FROM table
WHERE dt::date = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

Or the standard version:

SELECT *
FROM table
WHERE CAST(dt AS DATE) = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

The extract function doesn't understand "date" and it returns a number.

Just add AsEnumerable() andToList() , so it looks like this

db.Favorites
    .Where(x => x.userId == userId)
    .Join(db.Person, x => x.personId, y => y.personId, (x, y).ToList().AsEnumerable()

ToList().AsEnumerable()

Granted, there are definitely different thinking, in my world, I cannot enforce "Never pass a null" because I am dealing with uncontrollable third parties like API callers, database records, former programmers etc... so I am paranoid and defensive in approaches. Since you are on Java8 or later there is a bit cleaner approach than an if block.

public String foo(@Nullable String mayBeNothing) {
   return Optional.ofNullable(mayBeNothing).orElse("Really Nothing");
}

You can also throw some exception in there by swapping .orElse to orElseThrow(() -> new Exception("Dont' send a null")).

If you don't want to use @Nullable, which adds nothing functionally, why not just name the parameter with mayBe... so your intention is clear.

$("form#submit input").on('keypress',function(event) {
  event.preventDefault();
  if (event.which === 13) {
    $('button.submit').trigger('click');
  }
});

Rda is just a short name for RData. You can just save(), load(), attach(), etc. just like you do with RData.

Rds stores a single R object. Yet, beyond that simple explanation, there are several differences from a "standard" storage. Probably this R-manual Link to readRDS() function clarifies such distinctions sufficiently.

So, answering your questions:

• The difference is not about the compression, but serialization (See this page)
• Like shown in the manual page, you may wanna use it to restore a certain object with a different name, for instance.
• You may readRDS() and save(), or load() and saveRDS() selectively.

I encountered this running a brand new project. Neither the Allow or Always Allow button seemed to work, however it wasn't giving me the 'incorrect password' shaking feedback. What was happening was that there were multiple dialog boxes all in the same position, so as I entered a password and clicked Allow nothing changed visually. I ended up having at least 3 dialogs all stacked up on each other, which I only discovered when I tried dragging the dialog. Entering passwords into each of them let my project finish building.

# sudo apt-get install g++-multilib

Should fix this error on 64-bit machines (Debian/Ubuntu).

You can simply use this:

if ($("#one")){
   alert('yes');
}

if ($("#two")){
   alert('yes');
}

if ($("#three")){
   alert('yes');
}

if ($("#four")){
   alert('no');
}

Sorry, my mistake, it does not work.

PdfiumViewer is great, but relatively tightly coupled to System.Drawingand WinForms. For this reason I created my own wrapper around PDFium: PDFiumSharp

Pages can be rendered to a PDFiumBitmap which in turn can be saved to disk or exposed as a stream. This way any framework capable of loading an image in BMP format from a stream can use this library to display pdf pages.

For example in a WPF application you could use the following method to render a pdf page:

using System.Linq;
using System.Windows;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using PDFiumSharp;

static class PdfRenderer
{
    public static ImageSource RenderPage(string filename, int pageIndex, string password = null, bool withTransparency = true)
    {
        using (var doc = new PdfDocument(filename, password))
        {
            var page = doc.Pages[pageIndex];
            using (var bitmap = new PDFiumBitmap((int)page.Width, (int)page.Height, withTransparency))
            {
                page.Render(bitmap);
                return new BmpBitmapDecoder(bitmap.AsBmpStream(), BitmapCreateOptions.None, BitmapCacheOption.OnLoad).Frames.First();
            }
        }
    }
}

The USAGE-privilege in mysql simply means that there are no privileges for the user 'phpadmin'@'localhost' defined on global level *.*. Additionally the same user has ALL-privilege on database phpmyadmin phpadmin.*.

So if you want to remove all the privileges and start totally from scratch do the following:

• Revoke all privileges on database level:

  REVOKE ALL PRIVILEGES ON phpmyadmin.* FROM 'phpmyadmin'@'localhost';

• Drop the user 'phpmyadmin'@'localhost'

  DROP USER 'phpmyadmin'@'localhost';

Above procedure will entirely remove the user from your instance, this means you can recreate him from scratch.

To give you a bit background on what described above: as soon as you create a user the mysql.user table will be populated. If you look on a record in it, you will see the user and all privileges set to 'N'. If you do a show grants for 'phpmyadmin'@'localhost'; you will see, the allready familliar, output above. Simply translated to "no privileges on global level for the user". Now your grant ALL to this user on database level, this will be stored in the table mysql.db. If you do a SELECT * FROM mysql.db WHERE db = 'nameofdb'; you will see a 'Y' on every priv.

Above described shows the scenario you have on your db at the present. So having a user that only has USAGE privilege means, that this user can connect, but besides of SHOW GLOBAL VARIABLES; SHOW GLOBAL STATUS; he has no other privileges.

You could do Char(13) and Char(10). Cr and Lf.

Char() works in SQL Server, I don't know about other databases.

One important note, the solution mentioned above will not work on local host, you have to upload your code to server and then it will work. I was getting no error, than bad request, the problem was I was using localhost (test.dev,myproject.git). Both solution above work, the solution that uses SSL cert is recommended.

1. Go to https://curl.haxx.se/docs/caextract.html, download the latest cacert.pem. Store is somewhere (not in public folder - but will work regardless)

2. Use this code

".$result; //echo "
Path:".$_SERVER['DOCUMENT_ROOT'] . "/ssl/cacert.pem"; // this is for troubleshooting only ?>

3. Upload the code to live server and test.

For a terse, pure flexbox option, group the left-aligned items and the right-aligned items:

<div class="wrap">

    <span>Two</span>
  </div>
  <div>Three</div>
</div>

and use space-between:

.wrap {
  display: flex;
  background: #ccc;
  justify-content: space-between;
}

This way you can group multiple items to the right(or just one).

$total_ratings is an array.

A super quick and handy fix is to abuse Visual Studio's incredible intellisense by temporarily referencing the class somewhere.

Example:

System.Runtime.CompilerServices.ExtensionAttribute x = null;

When building or hovering the cursor over the line you can view the following error:

'System.Runtime.CompilerServices.ExtensionAttribute' exists in both 'C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll'

This tells you the two sources causing the conflict immediately.

System.Core.dll is the .dll file that you want to keep, so delete the other one.

I found mine sitting in the bin directory, but it may be elsewhere in the project.

As a matter of fact this is worth bearing in mind, because since the bin directory might not be included as part of the TFS change-set, it can explain why checking in your changes doesn't resolve the issue for other members of your team.

We created soyuz-to to simplify 1 problem: how to convert X to Y (e.g. String to Integer). Constructing of an object is also kind of conversion so it has a simple function to construct Map, List, Set:

import io.thedocs.soyuz.to;

List<String> names = to.list("John", "Fedor");

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

Your modifications are in a different branch than the original branch, which simplifies stuff because you get updates in one branch, and your work is in another branch.

Assuming the original branch is named master, which the case in 99% of git repos, you have to fetch the state of origin, and merge origin/master updates into your local master:

 git fetch origin
 git checkout master
 git merge origin/master

To switch to your branch, just do

 git checkout branch1

you may add an interceptor .

myModule.config(['$httpProvider', function($httpProvider) {
 $httpProvider.interceptors.push('noCacheInterceptor');
}]).factory('noCacheInterceptor', function () {
            return {
                request: function (config) {
                    console.log(config.method);
                    console.log(config.url);
                    if(config.method=='GET'){
                        var separator = config.url.indexOf('?') === -1 ? '?' : '&';
                        config.url = config.url+separator+'noCache=' + new Date().getTime();
                    }
                    console.log(config.method);
                    console.log(config.url);
                    return config;
               }
           };
    });

you should remove console.log lines after verifying.

What you actually have is an Activity (even if it looks like a Dialog), therefore you should call setFinishOnTouchOutside(false) from your activity if you want to keep it open when the background activity is clicked.

EDIT: This only works with android API level 11 or greater

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

String s = new String("FFFF") creates 2 objects: "FFFF" string and String object, which point to "FFFF" string, so it is like pointer to pointer (reference to reference, I am not keen with terminology).

It is said you should never use new String("FFFF")

I have the same problem. but when i add direction: rtl; in tabs and accordion combo but it crashes my structure.

The way to do it is add div with direction: rtl; as parent element, and for child div set direction: ltr;.

I use this first https://api.jquery.com/wrap/

$( ".your selector of child element" ).wrap( "<div class='scroll'></div>" );

then just simply work with css :)

In children div add to css

 .your_class {
            direction: ltr;    
        }

And to parent div added by jQuery with class .scroll

.scroll {
            unicode-bidi:bidi-override;
            direction: rtl;
            overflow: scroll;
            overflow-x: hidden!important;
        }

Works prefect for me

http://jsfiddle.net/jw3jsz08/1/

How about a workaround? In my case I took the value of the textarea in a jQuery variable, and changed all "<p>&nbsp" to <p class="clear"> and clear class to have certain height and margin, as the following example:

jQuery

tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p>&nbsp/g, '<p class="clear">');

the val is then saved to the database with the new val.

CSS

p.clear{height: 2px; margin-bottom: 3px;}

You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.

Hope that helps!

In case of Request to a REST Service:

You need to allow the CORS (cross origin sharing of resources) on the endpoint of your REST Service with Spring annotation:

@CrossOrigin(origins = "http://localhost:8080")

Very good tutorial: https://spring.io/guides/gs/rest-service-cors/

Based on tips from https://developer.mozilla.org/en-US/docs/CSS/background-size I end up with the following recipe that worked for me

body {
        overflow-y: hidden ! important;
        overflow-x: hidden ! important;
        background-color: #f8f8f8;
        background-image: url('index.png');
        /*background-size: cover;*/
        background-size: contain;
        background-repeat: no-repeat;
        background-position: right;
}

To expand a little on the other answers:

In the line:

def wrapper(func, *args):

The * next to args means "take the rest of the parameters given and put them in a list called args".

In the line:

    func(*args)

The * next to args here means "take this list called args and 'unwrap' it into the rest of the parameters.

So you can do the following:

def wrapper1(func, *args): # with star
    func(*args)

def wrapper2(func, args): # without star
    func(*args)

def func2(x, y, z):
    print x+y+z

wrapper1(func2, 1, 2, 3)
wrapper2(func2, [1, 2, 3])

In wrapper2, the list is passed explicitly, but in both wrappers args contains the list [1,2,3].

Change the rule on your <a> element from:

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
}?

to

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
    width:100%;
    text-align:center;
}?

Just add two new rules (width:100%; and text-align:center;). You need to make the anchor expand to take up the full width of the list item and then text-align center it.

jsFiddle example

You can also use listView.setOnItemLongClickListener to delete selected item. Below is the code.

// listView = name of your ListView

  listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int 
        position, long id) {

        // it will get the position of selected item from the ListView

final int selected_item = position;

            new AlertDialog.Builder(MainActivity.this).
                    setIcon(android.R.drawable.ic_delete)
                    .setTitle("Are you sure...")
                    .setMessage("Do you want to delete the selected item..?")
                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which)
                        {
                            list.remove(selected_item);
                            arrayAdapter.notifyDataSetChanged();
                        }
                    })
                    .setNegativeButton("No" , null).show();

            return true;
        }
    });

When using numbers as the key, I suppose you could also try this:

        Map<Long, String> map = new HashMap<>();
        map.put(4L, "The First");
        map.put(6L, "The Second");
        map.put(11L, "The Last");

        long lastKey = 0;
        //you entered Map<Long, String> entry
        for (Map.Entry<Long, String> entry : map.entrySet()) {
            lastKey = entry.getKey();
        }
        System.out.println(lastKey); // 11

Rather than finding which version you are using you can rephrase your question to "which version of ECMA script does my browser's JavaScript/JSscript engine conform to".

For IE :

alert(@_jscript_version);      //IE

Refer Squeegy's answer for non-IE versions :)

How does your .NET Webservice look like?

I had the same effect using ksoap 2.3 from code.google.com. I followed the tutorial on The Code Project (which is great BTW.)

And everytime I used

    Integer result = (Integer)envelope.getResponse();

to get the result of a my webservice (regardless of the type, I tried Object, String, int) I ran into the org.ksoap2.serialization.SoapPrimitive exception.

I found a solution (workaround). The first thing I had to do was to remove the "SoapRpcMethod() attribute from my webservice methods.

    [SoapRpcMethod(), WebMethod]
    public Object GetInteger1(int i)
    {
        // android device will throw exception
        return 0;
    }

    [WebMethod]
    public Object GetInteger2(int i)
    {
        // android device will get the value
        return 0;
    }

Then I changed my Android code to:

    SoapPrimitive result = (SoapPrimitive)envelope.getResponse();

However, I get a SoapPrimitive object, which has a "value" filed that is private. Luckily the value is passed through the toString() method, so I use Integer.parseInt(result.toString()) to get my value, which is enough for me, because I don't have any complex types that I need to get from my Web service.

Here is the full source:

private static final String SOAP_ACTION = "http://tempuri.org/GetInteger2";
private static final String METHOD_NAME = "GetInteger2";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://10.0.2.2:4711/Service1.asmx";

public int GetInteger2() throws IOException, XmlPullParserException {
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    PropertyInfo pi = new PropertyInfo();
    pi.setName("i");
    pi.setValue(123);
    request.addProperty(pi);

    SoapSerializationEnvelope envelope =
        new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);

    AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
    androidHttpTransport.call(SOAP_ACTION, envelope);

    SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
    return Integer.parseInt(result.toString());
}

Try entering the url inside the function

$location.url('http://www.google.com')

There are possible steps to enable auto increment for a column. I guess the phpMyAdmin version is 3.5.5 but not sure.

Click on Table > Structure tab > Under Action Click Primary (set as primary), click on Change on the pop-up window, scroll left and check A_I. Also make sure you have selected None for Default

You can return a number by using this trick:
not recommended

[a] + b - 0

Example :

let output = [5] + 6 - 0;
console.log(output); // 56
console.log(typeof output); // number

@user3168844: try the below code:

import java.util.Scanner;

public class LargestSmallestNum {

    public void findLargestSmallestNo() {

        int smallest = Integer.MAX_VALUE;
        int large = 0;
        int num;

        System.out.println("enter the number");

        Scanner input = new Scanner(System.in);

        int n = input.nextInt();

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

            num = input.nextInt();

            if (num > large)
                large = num;

            if (num < smallest)
                smallest = num;

            System.out.println("the largest is:" + large);
            System.out.println("Smallest no is : "  + smallest);
        }
    }

    public static void main(String...strings){
        LargestSmallestNum largestSmallestNum = new LargestSmallestNum();
        largestSmallestNum.findLargestSmalestNo();
    }
}

By far the easiest method is to subtract one date from the other and compare the result.

var oDateOne = new Date();_x000D_
var oDateTwo = new Date();_x000D_
_x000D_
alert(oDateOne - oDateTwo === 0);_x000D_
alert(oDateOne - oDateTwo < 0);_x000D_
alert(oDateOne - oDateTwo > 0);

This method will work for both iOS 6 and 7

- (float)heightForLabelSize:(CGSize)maximumLabelSize  Font:(UIFont *)font String:(NSString*)string {

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    NSDictionary *stringAttributes = [NSDictionary dictionaryWithObject:font forKey: NSFontAttributeName];

    CGSize adjustedLabelSize = [string maximumLabelSize
                                                                  options:NSStringDrawingTruncatesLastVisibleLine|NSStringDrawingUsesLineFragmentOrigin

}
else {
    CGSize adjustedLabelSize = [string sizeWithFont:font constrainedToSize:maximumLabelSize lineBreakMode:NSLineBreakByWordWrapping];

    return adjustedLabelSize.height;

I was using View.INVISIBLE and View.VISIBLE and the ProgressBar would slowly flash instead of constantly being visible, switched to View.GONE and View.VISIBLE and it works perfectly

To somewhat expand on the earlier answers here, there are a number of details which are commonly overlooked.

• Prefer subprocess.run() over subprocess.check_call() and friends over subprocess.call() over subprocess.Popen() over os.system() over os.popen()
• Understand and probably use text=True, aka universal_newlines=True.
• Understand the meaning of shell=True or shell=False and how it changes quoting and the availability of shell conveniences.
• Understand differences between sh and Bash
• Understand how a subprocess is separate from its parent, and generally cannot change the parent.
• Avoid running the Python interpreter as a subprocess of Python.

These topics are covered in some more detail below.

Prefer subprocess.run() or subprocess.check_call()

The subprocess.Popen() function is a low-level workhorse but it is tricky to use correctly and you end up copy/pasting multiple lines of code ... which conveniently already exist in the standard library as a set of higher-level wrapper functions for various purposes, which are presented in more detail in the following.

Here's a paragraph from the documentation:

The recommended approach to invoking subprocesses is to use the run() function for all use cases it can handle. For more advanced use cases, the underlying Popen interface can be used directly.

Unfortunately, the availability of these wrapper functions differs between Python versions.

• subprocess.run() was officially introduced in Python 3.5. It is meant to replace all of the following.
• subprocess.check_output() was introduced in Python 2.7 / 3.1. It is basically equivalent to subprocess.run(..., check=True, stdout=subprocess.PIPE).stdout
• subprocess.check_call() was introduced in Python 2.5. It is basically equivalent to subprocess.run(..., check=True)
• subprocess.call() was introduced in Python 2.4 in the original subprocess module (PEP-324). It is basically equivalent to subprocess.run(...).returncode

High-level API vs subprocess.Popen()

The refactored and extended subprocess.run() is more logical and more versatile than the older legacy functions it replaces. It returns a CompletedProcess object which has various methods which allow you to retrieve the exit status, the standard output, and a few other results and status indicators from the finished subprocess.

subprocess.run() is the way to go if you simply need a program to run and return control to Python. For more involved scenarios (background processes, perhaps with interactive I/O with the Python parent program) you still need to use subprocess.Popen() and take care of all the plumbing yourself. This requires a fairly intricate understanding of all the moving parts and should not be undertaken lightly. The simpler Popen object represents the (possibly still-running) process which needs to be managed from your code for the remainder of the lifetime of the subprocess.

It should perhaps be emphasized that just subprocess.Popen() merely creates a process. If you leave it at that, you have a subprocess running concurrently alongside with Python, so a "background" process. If it doesn't need to do input or output or otherwise coordinate with you, it can do useful work in parallel with your Python program.

Avoid os.system() and os.popen()

Since time eternal (well, since Python 2.5) the os module documentation has contained the recommendation to prefer subprocess over os.system():

The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function.

The problems with system() are that it's obviously system-dependent and doesn't offer ways to interact with the subprocess. It simply runs, with standard output and standard error outside of Python's reach. The only information Python receives back is the exit status of the command (zero means success, though the meaning of non-zero values is also somewhat system-dependent).

PEP-324 (which was already mentioned above) contains a more detailed rationale for why os.system is problematic and how subprocess attempts to solve those issues.

os.popen() used to be even more strongly discouraged:

Deprecated since version 2.6: This function is obsolete. Use the subprocess module.

However, since sometime in Python 3, it has been reimplemented to simply use subprocess, and redirects to the subprocess.Popen() documentation for details.

Understand and usually use check=True

You'll also notice that subprocess.call() has many of the same limitations as os.system(). In regular use, you should generally check whether the process finished successfully, which subprocess.check_call() and subprocess.check_output() do (where the latter also returns the standard output of the finished subprocess). Similarly, you should usually use check=True with subprocess.run() unless you specifically need to allow the subprocess to return an error status.

In practice, with check=True or subprocess.check_*, Python will throw a CalledProcessError exception if the subprocess returns a nonzero exit status.

A common error with subprocess.run() is to omit check=True and be surprised when downstream code fails if the subprocess failed.

On the other hand, a common problem with check_call() and check_output() was that users who blindly used these functions were surprised when the exception was raised e.g. when grep did not find a match. (You should probably replace grep with native Python code anyway, as outlined below.)

All things counted, you need to understand how shell commands return an exit code, and under what conditions they will return a non-zero (error) exit code, and make a conscious decision how exactly it should be handled.

Understand and probably use text=True aka universal_newlines=True

Since Python 3, strings internal to Python are Unicode strings. But there is no guarantee that a subprocess generates Unicode output, or strings at all.

(If the differences are not immediately obvious, Ned Batchelder's Pragmatic Unicode is recommended, if not outright obligatory, reading. There is a 36-minute video presentation behind the link if you prefer, though reading the page yourself will probably take significantly less time.)

Deep down, Python has to fetch a bytes buffer and interpret it somehow. If it contains a blob of binary data, it shouldn't be decoded into a Unicode string, because that's error-prone and bug-inducing behavior - precisely the sort of pesky behavior which riddled many Python 2 scripts, before there was a way to properly distinguish between encoded text and binary data.

With text=True, you tell Python that you, in fact, expect back textual data in the system's default encoding, and that it should be decoded into a Python (Unicode) string to the best of Python's ability (usually UTF-8 on any moderately up to date system, except perhaps Windows?)

If that's not what you request back, Python will just give you bytes strings in the stdout and stderr strings. Maybe at some later point you do know that they were text strings after all, and you know their encoding. Then, you can decode them.

normal = subprocess.run([external, arg],
    stdout=subprocess.PIPE, stderr=subprocess.PIPE,
    check=True,
    text=True)
print(normal.stdout)

convoluted = subprocess.run([external, arg],
    stdout=subprocess.PIPE, stderr=subprocess.PIPE,
    check=True)
# You have to know (or guess) the encoding
print(convoluted.stdout.decode('utf-8'))

Python 3.7 introduced the shorter and more descriptive and understandable alias text for the keyword argument which was previously somewhat misleadingly called universal_newlines.

Understand shell=True vs shell=False

With shell=True you pass a single string to your shell, and the shell takes it from there.

With shell=False you pass a list of arguments to the OS, bypassing the shell.

When you don't have a shell, you save a process and get rid of a fairly substantial amount of hidden complexity, which may or may not harbor bugs or even security problems.

On the other hand, when you don't have a shell, you don't have redirection, wildcard expansion, job control, and a large number of other shell features.

A common mistake is to use shell=True and then still pass Python a list of tokens, or vice versa. This happens to work in some cases, but is really ill-defined and could break in interesting ways.

# XXX AVOID THIS BUG
buggy = subprocess.run('dig +short stackoverflow.com')

# XXX AVOID THIS BUG TOO
broken = subprocess.run(['dig', '+short', 'stackoverflow.com'],
    shell=True)

# XXX DEFINITELY AVOID THIS
pathological = subprocess.run(['dig +short stackoverflow.com'],
    shell=True)

correct = subprocess.run(['dig', '+short', 'stackoverflow.com'],
    # Probably don't forget these, too
    check=True, text=True)

# XXX Probably better avoid shell=True
# but this is nominally correct
fixed_but_fugly = subprocess.run('dig +short stackoverflow.com',
    shell=True,
    # Probably don't forget these, too
    check=True, text=True)

The common retort "but it works for me" is not a useful rebuttal unless you understand exactly under what circumstances it could stop working.

Refactoring Example

Very often, the features of the shell can be replaced with native Python code. Simple Awk or sed scripts should probably simply be translated to Python instead.

To partially illustrate this, here is a typical but slightly silly example which involves many shell features.

cmd = '''while read -r x;
   do ping -c 3 "$x" | grep 'round-trip min/avg/max'
   done <hosts.txt'''

# Trivial but horrible
results = subprocess.run(
    cmd, shell=True, universal_newlines=True, check=True)
print(results.stdout)

# Reimplement with shell=False
with open('hosts.txt') as hosts:
    for host in hosts:
        host = host.rstrip('\n')  # drop newline
        ping = subprocess.run(
             ['ping', '-c', '3', host],
             text=True,
             stdout=subprocess.PIPE,
             check=True)
        for line in ping.stdout.split('\n'):
             if 'round-trip min/avg/max' in line:
                 print('{}: {}'.format(host, line))

Some things to note here:

• With shell=False you don't need the quoting that the shell requires around strings. Putting quotes anyway is probably an error.
• It often makes sense to run as little code as possible in a subprocess. This gives you more control over execution from within your Python code.
• Having said that, complex shell pipelines are tedious and sometimes challenging to reimplement in Python.

The refactored code also illustrates just how much the shell really does for you with a very terse syntax -- for better or for worse. Python says explicit is better than implicit but the Python code is rather verbose and arguably looks more complex than this really is. On the other hand, it offers a number of points where you can grab control in the middle of something else, as trivially exemplified by the enhancement that we can easily include the host name along with the shell command output. (This is by no means challenging to do in the shell, either, but at the expense of yet another diversion and perhaps another process.)

Common Shell Constructs

For completeness, here are brief explanations of some of these shell features, and some notes on how they can perhaps be replaced with native Python facilities.

• Globbing aka wildcard expansion can be replaced with glob.glob() or very often with simple Python string comparisons like for file in os.listdir('.'): if not file.endswith('.png'): continue. Bash has various other expansion facilities like .{png,jpg} brace expansion and {1..100} as well as tilde expansion (~ expands to your home directory, and more generally ~account to the home directory of another user)
• Shell variables like $SHELL or $my_exported_var can sometimes simply be replaced with Python variables. Exported shell variables are available as e.g. os.environ['SHELL'] (the meaning of export is to make the variable available to subprocesses -- a variable which is not available to subprocesses will obviously not be available to Python running as a subprocess of the shell, or vice versa. The env= keyword argument to subprocess methods allows you to define the environment of the subprocess as a dictionary, so that's one way to make a Python variable visible to a subprocess). With shell=False you will need to understand how to remove any quotes; for example, cd "$HOME" is equivalent to os.chdir(os.environ['HOME']) without quotes around the directory name. (Very often cd is not useful or necessary anyway, and many beginners omit the double quotes around the variable and get away with it until one day ...)
• Redirection allows you to read from a file as your standard input, and write your standard output to a file. grep 'foo' <inputfile >outputfile opens outputfile for writing and inputfile for reading, and passes its contents as standard input to grep, whose standard output then lands in outputfile. This is not generally hard to replace with native Python code.
• Pipelines are a form of redirection. echo foo | nl runs two subprocesses, where the standard output of echo is the standard input of nl (on the OS level, in Unix-like systems, this is a single file handle). If you cannot replace one or both ends of the pipeline with native Python code, perhaps think about using a shell after all, especially if the pipeline has more than two or three processes (though look at the pipes module in the Python standard library or a number of more modern and versatile third-party competitors).
• Job control lets you interrupt jobs, run them in the background, return them to the foreground, etc. The basic Unix signals to stop and continue a process are of course available from Python, too. But jobs are a higher-level abstraction in the shell which involve process groups etc which you have to understand if you want to do something like this from Python.
• Quoting in the shell is potentially confusing until you understand that everything is basically a string. So ls -l / is equivalent to 'ls' '-l' '/' but the quoting around literals is completely optional. Unquoted strings which contain shell metacharacters undergo parameter expansion, whitespace tokenization and wildcard expansion; double quotes prevent whitespace tokenization and wildcard expansion but allow parameter expansions (variable substitution, command substitution, and backslash processing). This is simple in theory but can get bewildering, especially when there are several layers of interpretation (a remote shell command, for example).

Understand differences between sh and Bash

subprocess runs your shell commands with /bin/sh unless you specifically request otherwise (except of course on Windows, where it uses the value of the COMSPEC variable). This means that various Bash-only features like arrays, [[ etc are not available.

If you need to use Bash-only syntax, you can pass in the path to the shell as executable='/bin/bash' (where of course if your Bash is installed somewhere else, you need to adjust the path).

subprocess.run('''
    # This for loop syntax is Bash only
    for((i=1;i<=$#;i++)); do
        # Arrays are Bash-only
        array[i]+=123
    done''',
    shell=True, check=True,
    executable='/bin/bash')

A subprocess is separate from its parent, and cannot change it

A somewhat common mistake is doing something like

subprocess.run('cd /tmp', shell=True)
subprocess.run('pwd', shell=True)  # Oops, doesn't print /tmp

The same thing will happen if the first subprocess tries to set an environment variable, which of course will have disappeared when you run another subprocess, etc.

A child process runs completely separate from Python, and when it finishes, Python has no idea what it did (apart from the vague indicators that it can infer from the exit status and output from the child process). A child generally cannot change the parent's environment; it cannot set a variable, change the working directory, or, in so many words, communicate with its parent without cooperation from the parent.

The immediate fix in this particular case is to run both commands in a single subprocess;

subprocess.run('cd /tmp; pwd', shell=True)

though obviously this particular use case isn't very useful; instead, use the cwd keyword argument, or simply os.chdir() before running the subprocess. Similarly, for setting a variable, you can manipulate the environment of the current process (and thus also its children) via

os.environ['foo'] = 'bar'

or pass an environment setting to a child process with

subprocess.run('echo "$foo"', shell=True, env={'foo': 'bar'})

(not to mention the obvious refactoring subprocess.run(['echo', 'bar']); but echo is a poor example of something to run in a subprocess in the first place, of course).

Don't run Python from Python

This is slightly dubious advice; there are certainly situations where it does make sense or is even an absolute requirement to run the Python interpreter as a subprocess from a Python script. But very frequently, the correct approach is simply to import the other Python module into your calling script and call its functions directly.

If the other Python script is under your control, and it isn't a module, consider turning it into one. (This answer is too long already so I will not delve into details here.)

If you need parallelism, you can run Python functions in subprocesses with the multiprocessing module. There is also threading which runs multiple tasks in a single process (which is more lightweight and gives you more control, but also more constrained in that threads within a process are tightly coupled, and bound to a single GIL.)

You need to leverage the @ViewChild decorator to reference the child component from the parent one by injection:

import { Component, ViewChild } from 'angular2/core';  

(...)

@Component({
  selector: 'my-app',
  template: `
    <h1>My First Angular 2 App</h1>
    <child></child>
    <button (click)="submit()">Submit</button>
  `,
  directives:[App]
})
export class AppComponent { 
  @ViewChild(Child) child:Child;

  (...)

  someOtherMethod() {
    this.searchBar.someMethod();
  }
}

Here is the updated plunkr: http://plnkr.co/edit/mrVK2j3hJQ04n8vlXLXt?p=preview.

You can notice that the @Query parameter decorator could also be used:

export class AppComponent { 
  constructor(@Query(Child) children:QueryList<Child>) {
    this.childcmp = children.first();
  }

  (...)
}

A simpler answer is to manually upload the README.MD file from your computer to GitHub. Worked very well for me.

Both top answers are incorrect.

A short one-liner that uses pure JavaScript, accounts for the local timezone and requires no extra functions to be defined:

const element = document.getElementById('date-input');_x000D_
element.valueAsNumber = Date.now()-(new Date()).getTimezoneOffset()*60000;

<input id='date-input' type='date'>

This gets the current datetime in milliseconds (since epoch) and applies the timezone offset in milliseconds (minutes * 60k minutes per millisecond).

You can set the date using element.valueAsDate but then you have an extra call to the Date() constructor.

I always find images helpful when learning a new concept, so this is a supplemental answer.

The %p means a percentage of the parent, that is, a percentage of the narrowest dimension of whatever view we set our drawable on. The images above were generated by changing the gradientRadius in this code

my_gradient_drawable

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient
        android:type="radial"
        android:gradientRadius="10%p"
        android:startColor="#f6ee19"
        android:endColor="#115ede" />
</shape>

Which can be set on a view's background attribute like this

<View
    android:layout_width="200dp"
    android:layout_height="100dp"
    android:background="@drawable/my_gradient_drawable"/>

Center

You can change the center of the radius with

android:centerX="0.2"
android:centerY="0.7"

where the decimals are fractions of the width and height for x and y respectively.

Documentation

Here are some notes from the documentation explaining things a little more.

android:gradientRadius

Radius of the gradient, used only with radial gradient. May be an explicit dimension or a fractional value relative to the shape's minimum dimension.

May be a floating point value, such as "1.2".

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.

Code snippet above provides incorrect byte order in string, so I fixed it a bit.

char const hex[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A',   'B','C','D','E','F'};

std::string byte_2_str(char* bytes, int size) {
  std::string str;
  for (int i = 0; i < size; ++i) {
    const char ch = bytes[i];
    str.append(&hex[(ch  & 0xF0) >> 4], 1);
    str.append(&hex[ch & 0xF], 1);
  }
  return str;
}

In above code, you don't pass the kml data to your mapView anywhere in your code, as far as I can see. To display the route, you should parse the kml data i.e. via SAX parser, then display the route markers on the map.

See the code below for an example, but it's not complete though - just for you as a reference and get some idea.

This is a simple bean I use to hold the route information I will be parsing.

package com.myapp.android.model.navigation;

import java.util.ArrayList;
import java.util.Iterator;


public class NavigationDataSet { 

private ArrayList<Placemark> placemarks = new ArrayList<Placemark>();
private Placemark currentPlacemark;
private Placemark routePlacemark;

public String toString() {
    String s= "";
    for (Iterator<Placemark> iter=placemarks.iterator();iter.hasNext();) {
        Placemark p = (Placemark)iter.next();
        s += p.getTitle() + "\n" + p.getDescription() + "\n\n";
    }
    return s;
}

public void addCurrentPlacemark() {
    placemarks.add(currentPlacemark);
}

public ArrayList<Placemark> getPlacemarks() {
    return placemarks;
}

public void setPlacemarks(ArrayList<Placemark> placemarks) {
    this.placemarks = placemarks;
}

public Placemark getCurrentPlacemark() {
    return currentPlacemark;
}

public void setCurrentPlacemark(Placemark currentPlacemark) {
    this.currentPlacemark = currentPlacemark;
}

public Placemark getRoutePlacemark() {
    return routePlacemark;
}

public void setRoutePlacemark(Placemark routePlacemark) {
    this.routePlacemark = routePlacemark;
}

}

And the SAX Handler to parse the kml:

package com.myapp.android.model.navigation;

import android.util.Log;

My feeling is 409 Conflict is the most appropriate, however, seldom seen in the wild of course:

The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

You have 2 choices:

1) Either specify the column name list (without the identity column).

2) SET IDENTITY_INSERT tablename ON, followed by insert statements that provide explicit values for the identity column, followed by SET IDENTITY_INSERT tablename OFF.

If you are avoiding a column name list, perhaps this 'trick' might help?:

-- Get a comma separated list of a table's column names
SELECT STUFF(
(SELECT 
',' + COLUMN_NAME AS [text()]
FROM 
INFORMATION_SCHEMA.COLUMNS
WHERE 
TABLE_NAME = 'TableName'
Order By Ordinal_position
FOR XML PATH('')
), 1,1, '')

Here is how I would do it if working with a large number of "to remove" values that would take a long time to manually remove.

• -Put Original List in Column A -Put To Remove list in Column B -Select both columns, then "Conditional Formatting"
  -Select "Hightlight Cells Rules" --> "Duplicate Values"
  -The duplicates should be hightlighted in both columns
  -Then select Column A and then "Sort & Filter" ---> "Custom Sort"
  -In the dialog box that appears, select the middle option "Sort On" and pick "Cell Color"
  -Then select the next option "Sort Order" and choose "No Cell Color" "On bottom"
  -All the highlighted cells should be at the top of the list. -Select all the highlighted cells by scrolling down the list, then click delete.

Maven advantages over ant are quite a few. I try to summarize them here.

Convention over Configuration
Maven uses a distinctive approach for the project layout and startup, that makes easy to just jump in a project. Usually it only takes the checkount and the maven command to get the artifacts of the project.

Project Modularization
Project conventions suggest (or better, force) the developer to modularize the project. Instead of a monolithic project you are often forced to divide your project in smaller sub components, which make it easier debug and manage the overall project structure

Dependency Management and Project Lifecycle
Overall, with a good SCM configuration and an internal repository, the dependency management is quite easy, and you are again forced to think in terms of Project Lifecycle - component versions, release management and so on. A little more complex than the ant something, but again, an improvement in quality of the project.

What is wrong with maven?
Maven is not easy. The build cycle (what gets done and when) is not so clear within the POM. Also, some issue arise with the quality of components and missing dependencies in public repositories.
The best approach (to me) is to have an internal repository for caching (and keeping) dependencies around, and to apply to release management of components. For projects bigger than the sample projects in a book, you will thank maven before or after

You can use PHP to add a stylesheet for IE 10

Like:

if (stripos($_SERVER['HTTP_USER_AGENT'], 'MSIE 10')) {
    <link rel="stylesheet" type="text/css" href="../ie10.css" />
}

Just write:

error_reporting(-1);

I wrote this piece of code for object comparison, and it seems to work. check the assertions:

function countProps(obj) {
    var count = 0;
    for (k in obj) {
        if (obj.hasOwnProperty(k)) {
            count++;
        }
    }
    return count;
};

function objectEquals(v1, v2) {

    if (typeof(v1) !== typeof(v2)) {
        return false;
    }

    if (typeof(v1) === "function") {
        return v1.toString() === v2.toString();
    }

    if (v1 instanceof Object && v2 instanceof Object) {
        if (countProps(v1) !== countProps(v2)) {
            return false;
        }
        var r = true;
        for (k in v1) {
            r = objectEquals(v1[k], v2[k]);
            if (!r) {
                return false;
            }
        }
        return true;
    } else {
        return v1 === v2;
    }
}

assert.isTrue(objectEquals(null,null));
assert.isFalse(objectEquals(null,undefined));

assert.isTrue(objectEquals("hi","hi"));
assert.isTrue(objectEquals(5,5));
assert.isFalse(objectEquals(5,10));

assert.isTrue(objectEquals([],[]));
assert.isTrue(objectEquals([1,2],[1,2]));
assert.isFalse(objectEquals([1,2],[2,1]));
assert.isFalse(objectEquals([1,2],[1,2,3]));

assert.isTrue(objectEquals({},{}));
assert.isTrue(objectEquals({a:1,b:2},{a:1,b:2}));
assert.isTrue(objectEquals({a:1,b:2},{b:2,a:1}));
assert.isFalse(objectEquals({a:1,b:2},{a:1,b:3}));

assert.isTrue(objectEquals({1:{name:"mhc",age:28}, 2:{name:"arb",age:26}},{1:{name:"mhc",age:28}, 2:{name:"arb",age:26}}));
assert.isFalse(objectEquals({1:{name:"mhc",age:28}, 2:{name:"arb",age:26}},{1:{name:"mhc",age:28}, 2:{name:"arb",age:27}}));

assert.isTrue(objectEquals(function(x){return x;},function(x){return x;}));
assert.isFalse(objectEquals(function(x){return x;},function(y){return y+2;}));

You need some form of iteration here, as val (except when called with a function) only works on the first element:

$("input[placeholder]").val($("input[placeholder]").attr("placeholder"));

should be:

$("input[placeholder]").each( function () {
    $(this).val( $(this).attr("placeholder") );
});

or

$("input[placeholder]").val(function() {
    return $(this).attr("placeholder");
});

To add on the good answers above you can also avoid setting explicitly the action in HTML and use an event handler in javascript, using "this" as the form to create the "FormData" object

Html form :

<form id="mainForm" class="" novalidate>
<!--Whatever here...-->
</form>

In your JS :

$("#mainForm").submit(function( event ) {
  event.preventDefault();
  const formData = new URLSearchParams(new FormData(this));
  fetch("http://localhost:8080/your/server",
    {   method: 'POST',
        mode : 'same-origin',
        credentials: 'same-origin' ,
        body : formData
    })
    .then(function(response) {
      return response.text()
    }).then(function(text) {
        //text is the server's response
    });
});

See https://bootstrap.themes.guide/how-to-customize-bootstrap.html

1. For simple CSS Overrides, you can add a custom.css below the bootstrap.css

   <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
   <link rel="stylesheet" type="text/css" href="css/custom.css">
   

2. For more extensive changes, SASS is the recommended method.

   • create your own custom.scss
   • import Bootstrap after the changes in custom.scss

   • For example, let’s change the body background-color to light-gray #eeeeee, and change the blue primary contextual color to Bootstrap's $purple variable...

     /* custom.scss */    
     
     /* import the necessary Bootstrap files */
     @import "bootstrap/functions";
     @import "bootstrap/variables";
     
     /* -------begin customization-------- */   
     
     /* simply assign the value */ 
     $body-bg: #eeeeee;
     
     /* or, use an existing variable */
     $theme-colors: (
       primary: $purple
     );
     /* -------end customization-------- */  
     
     /* finally, import Bootstrap to set the changes! */
     @import "bootstrap";
     

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

if it crashes on the delete line then you have almost certainly somehow corrupted the heap. We would need to see more code to diagnose the problem since the example you presented has no errors.

Perhaps you have a buffer overflow on the heap which corrupted the heap structures or even something as simple as a "double free" (or in the c++ case "double delete").

Also, as The Fuzz noted, you may have an error in your destructor as well.

And yes, it is completely normal and expected for delete to invoke the destructor, that is in fact one of its two purposes (call destructor then free memory).

To make print view look like tablet or desktop include bootstrap as .less, not as .css and then you can overwrite bootstrap responsive classes in the end of bootstrap_variables file for example like this:

@container-sm:      1200px;
@container-md:      1200px;
@container-lg:      1200px;
@screen-sm:         0;

Don't worry about putting this variables in the end of the file. LESS supports lazy loading of variables so they will be applied.

It is not recommended to use DataReader and Command.ExecuteReader to get just one value from the database. Instead, you should use Command.ExecuteScalar as following:

String sql = "SELECT ColumnNumber FROM learer WHERE learer.id = " + index;
SqlCommand cmd = new SqlCommand(sql,conn);
learerLabel.Text = (String) cmd.ExecuteScalar();

Here is more information about Connecting to database and managing data.

Now someone told me that this is not very good programming because I use the return statement inside a loop and this would cause garbage collection to malfunction.

That's incorrect, and suggests you should treat other advice from that person with a degree of skepticism.

The mantra of "only have one return statement" (or more generally, only one exit point) is important in languages where you have to manage all resources yourself - that way you can make sure you put all your cleanup code in one place.

It's much less useful in Java: as soon as you know that you should return (and what the return value should be), just return. That way it's simpler to read - you don't have to take in any of the rest of the method to work out what else is going to happen (other than finally blocks).

For jupyter lab this should work (@Alasja)

from IPython.display import HTML
HTML('''<script>

     stderr.forEach(ele => ele.style.display = 'none');
 }
 code_show_err = !code_show_err
} 
document.addEventListener('DOMContentLoaded', code_toggle_err);

To toggle on/off output_stderr, click <a onclick="javascript:code_toggle_err()">here</a>.''')

I meet the problem when using Firebase, i think different package cause the problem.

I solved by adding packeage of new app within Firebase Console, and download google-services.json again.

Do you have the line

apply plugin: 'com.google.gms.google-services' 

line at the bottom of your app's build.gradle file?

I saw some errors when it was on the top and as it's written here, it should be at the bottom.

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

var result = priceLog.GroupBy(s => s.LogDateTime.ToString("MMM yyyy")).Select(grp => new PriceLog() { LogDateTime = Convert.ToDateTime(grp.Key), Price = (int)grp.Average(p => p.Price) }).ToList();

I have converted it to int because my Price field was int and Average method return double .I hope this will help

Check these steps.

1. go to Sql Server Configuration management->SQL Server network config->protocols for 'servername' and check TCP/IP is enabled.
2. Open SSMS in run, and check you are able to login to server using specfied username/password and/or using windows authentication.
3. repeat step 1 for SQL native client config also

Remove /etc/my.cnf file and retry the installation, it worked for me for exactly same problem. :-)

import pandas as pd
header=['a','b','v']
df=pd.DataFrame(columns=header)
for i in range(len(doc_list)):
  d_id=(test_data.filenames[i]).split('\\')
  doc_id.append(d_id[len(d_id)-1])
  df['a']=doc_id
print(df.head())
df[column_names_to_be_updated]=np.asanyarray(data)
print(df.head())
df.to_csv('output.csv')

Using pandas dataframe,we can write to csv. First create a dataframe as per the your needs for storing in csv. Then create csv of the dataframe using pd.DataFrame.to_csv() API.

terrific answer from DuckPuncher, for Python3 make sure you install pdfminer2 and do:

import io

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage


def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = io.StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos = set()

    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages,
                                  password=password,
                                  caching=caching,
                                  check_extractable=True):
        interpreter.process_page(page)



    fp.close()
    device.close()
    text = retstr.getvalue()
    retstr.close()
    return text

I have used wamp server. I tried on

c:\wamp\bin\mysql\mysql5.5.8\bin\mysqldump -uroot -p db_name > c:\somefolder\filename.sql

root is my username for mysql, and if you have any password specify it with:

-p[yourpassword]

Hope it works.

Both C and C++ give you a lower level of abstraction that, with increased complexity, provides a breadth of access to underlying machine functionality that are not necessarily exposed with other languages. Compared to C, C++ adds the convenience of a fully object oriented language(reduced development time) which can, potentially, add an additional performance cost. In terms of real world applications, I see these languages applied in the following domains:

C

• Kernel level software.
• Hardware device drivers
• Applications where access to old, stable code is required.

C,C++

• Application or Server development where memory management needs to be fine tuned (and can't be left to generic garbage collection solutions).
• Development environments that require access to libraries that do not interface well with more modern managed languages.
• Although managed C++ can be used to access the .NET framework, it is not a seamless transition.

C# provides a managed memory model that adds a higher level of abstraction again. This level of abstraction adds convenience and improves development times, but complicates access to lower level APIs and makes specialized performance requirements problematic.

It is certainly possible to implement extremely high performance software in a managed memory environment, but awareness of the implications is essential.

The syntax of C# is certainly less demanding (and error prone) than C/C++ and has, for the initiated programmer, a shallower learning curve.

C#

• Rapid client application development.
• High performance Server development (StackOverflow for example) that benefits from the .NET framework.
• Applications that require the benefits of the .NET framework in the language it was designed for.

Johannes Rössel makes the valid point that the use C# Pointers, Unsafe and Unchecked keywords break through the layer of abstraction upon which C# is built. I would emphasize that type of programming is the exception to most C# development scenarios and not a fundamental part of the language (as is the case with C/C++).

In Swift 3

let langStr = Locale.current.languageCode

There’s also SenTestingKitAsync that lets you write code like this:

- (void)testAdditionAsync {
    [Calculator add:2 to:2 block^(int result) {
        STAssertEquals(result, 4, nil);
        STSuccess();
    }];
    STFailAfter(2.0, @"Timeout");
}

(See objc.io article for details.) And since Xcode 6 there’s an AsynchronousTesting category on XCTest that lets you write code like this:

XCTestExpectation *somethingHappened = [self expectationWithDescription:@"something happened"];
[testedObject doSomethigAsyncWithCompletion:^(BOOL succeeded, NSError *error) {
    [somethingHappened fulfill];
}];
[self waitForExpectationsWithTimeout:1 handler:NULL];

Have a look at the ImageView API. There are several setImage* methods. Which one to use depends on the image you provide. If you have the image as resource (e.g. file res/drawable/my_image.png)

ImageView img = new ImageView(this);  // or (ImageView) findViewById(R.id.myImageView);
img.setImageResource(R.drawable.my_image);

This worked for me:

#image-id {
    position: absolute;
    top: 0; left: 0; right: 0; bottom: 0;
    width: auto;
    margin: 0 auto;
}

First Solution:

You can call start activity inside your adapter like this:

public class YourAdapter extends Adapter {
     private Context context;

     public YourAdapter(Context context) {
          this.context = context;     
     }

     public View getView(...){
         View v;
         v.setOnClickListener(new OnClickListener() {
             void onClick() {
                 context.startActivity(...);
             }
         });
     }
}

Second Solution:

You can call onClickListener of your button out of the YourAdapter class. Follow these steps:

Craete an interface like this:

public YourInterface{
         public void  yourMethod(args...);
}

Then inside your adapter:

    public YourAdapter extends BaseAdapter{
               private YourInterface listener;

           public YourAdapter (Context context, YourInterface listener){
                    this.listener = listener;
                    this.context = context;
           }

           public View getView(...){
                View v;
         v.setOnClickListener(new OnClickListener() {
             void onClick() {
                 listener.yourMethod(args);
             }
         });
}

And where you initiate yourAdapter will be like this:

YourAdapter adapter = new YourAdapter(getContext(), (args) -> {
            startActivity(...);
        });

I just came across a similar situation and was surprised at the rounding issues of 'very large numbers' presented within SSMS v17.9.1 / SQL 2017.

I am not suggesting I have a solution, however I have observed that FORMAT presents a number which appears correct. I can not imply this reduces further rounding issues or is useful within a complicated mathematical function.

T SQL Code supplied which should clearly demonstrate my observations while enabling others to test their code and ideas should the need arise.

in my case, i have a cdn,and i am going to place all my processed static files (js,imgs,fonts...) into my cdn,suppose the url is http://my.cdn.com/

so if there is a js file which is the orginal refer url in html is './js/my.js' it should became http://my.cdn.com/js/my.js in production environment

in that case,what i need to do is just set publicpath equals http://my.cdn.com/ and webpack will automatic add that prefix

$ which pip

or

 $ pip -V 

execute this command into your terminal. It should display the location of executable file eg. /usr/local/bin/pip and the second command will display the version if the pip is installed correctly.

Assuming a simple table:

CREATE TABLE dbo.foo(ID INT IDENTITY(1,1), name SYSNAME);

We can capture IDENTITY values in a table variable for further consumption.

DECLARE @IDs TABLE(ID INT);

-- minor change to INSERT statement; add an OUTPUT clause:
INSERT dbo.foo(name) 
  OUTPUT inserted.ID INTO @IDs(ID)
SELECT N'Fred'
UNION ALL
SELECT N'Bob';

SELECT ID FROM @IDs;

The nice thing about this method is (a) it handles multi-row inserts (SCOPE_IDENTITY() only returns the last value) and (b) it avoids this parallelism bug, which can lead to wrong results, but so far is only fixed in SQL Server 2008 R2 SP1 CU5.

In .net VB - you could achieve control over columns and rows with the following in your razor file:

@Html.EditorFor(Function(model) model.generalNotes, New With {.htmlAttributes = New With {.class = "someClassIfYouWant", .rows = 5,.cols=6}})

You need to run this command in the top-level directory of a Selenium SVN repository checkout.

if (Enum.IsDefined(typeof(foo), value))
{
   return (Foo)Enum.Parse(typeof(foo), value);
}

Hope this helps

Edit This answer got down voted as value in my example is a string, where as the question asked for an int. My applogies; the following should be a bit clearer :-)

Type fooType = typeof(foo);

if (Enum.IsDefined(fooType , value.ToString()))
{
   return (Foo)Enum.Parse(fooType , value.ToString());
}

In general we use margins on one of the elements, not spacer elements.

1. It runs when a shared library is loaded, typically during program startup.
2. That's how all GCC attributes are; presumably to distinguish them from function calls.
3. GCC-specific syntax.
4. Yes, this works in C and C++.
5. No, the function does not need to be static.
6. The destructor runs when the shared library is unloaded, typically at program exit.

So, the way the constructors and destructors work is that the shared object file contains special sections (.ctors and .dtors on ELF) which contain references to the functions marked with the constructor and destructor attributes, respectively. When the library is loaded/unloaded the dynamic loader program (ld.so or somesuch) checks whether such sections exist, and if so, calls the functions referenced therein.

Come to think of it, there is probably some similar magic in the normal static linker so that the same code is run on startup/shutdown regardless if the user chooses static or dynamic linking.

Another way of solving this is to use the DictReader class, which "skips" the header row and uses it to allowed named indexing.

Given "foo.csv" as follows:

FirstColumn,SecondColumn
asdf,1234
qwer,5678

Use DictReader like this:

import csv
with open('foo.csv') as f:
    reader = csv.DictReader(f, delimiter=',')
    for row in reader:
        print(row['FirstColumn'])  # Access by column header instead of column number
        print(row['SecondColumn'])

Trivial (but working) solution:

echo -e "---------------------------- [UP]\r$PROC_NAME "

What you can do and what you should do are different matters.

If the list is very short, or you are only ever going to call find once then use the linear approach above.

However linear-search is one of the biggest evils I find in slow code, and consider using an ordered collection (set or multiset if you allow duplicates). If you need to keep a list for other reasons eg using an LRU technique or you need to maintain the insertion order or some other order, create an index for it. You can actually do that using a std::set of the list iterators (or multiset) although you need to maintain this any time your list is modified.

Not sure why they're doing this but, you could get around this by reseting the hash at the top of your page:

if (window.location.hash == "#_=_")
  window.location.hash = "";

The easiest (and standard) way to install Android SDK under OS X is to use brew.

brew install android-sdk

If you do not have homebrew, here's how to get it.

This will install Android SDK into /usr/local/Cellar/android-sdk/ and, at this moment, this is the best location to install it.

I found this old Thread while google'ing for generate_204 as Android seems to use this to determine if the wlan is open (response 204 is received) closed (no response at all) or blocked (redirect to captive portal is present). In that case a notification is shown that a log-in to WiFi is required...

Just use That.Its Easy.

I'm assuming that each argument to VA_ARGS will be comma separated. If so I think this should work as a pretty clean way to do this.

    return str[0] == char(0) ? 0 : (str[0] == c) + CountOccurances(str+1, c);
}

    static_assert(NUMARGS(hello, world) == 2, ":(")  ;
    return 0;

You need to use the iconv package, specifically its iconv function.

Strace stands out as a tool for investigating production systems where you can't afford to run these programs under a debugger. In particular, we have used strace in the following two situations:

• Program foo seems to be in deadlock and has become unresponsive. This could be a target for gdb; however, we haven't always had the source code or sometimes were dealing with scripted languages that weren't straight-forward to run under a debugger. In this case, you run strace on an already running program and you will get the list of system calls being made. This is particularly useful if you are investigating a client/server application or an application that interacts with a database
• Investigating why a program is slow. In particular, we had just moved to a new distributed file system and the new throughput of the system was very slow. You can specify strace with the '-T' option which will tell you how much time was spent in each system call. This helped to determine why the file system was causing things to slow down.

For an example of analyzing using strace see my answer to this question.

This is your 2nd question: string.lowercase[ord('a')-97:ord('n')-97:2] because 97==ord('a') -- if you want to learn a bit you should figure out the rest yourself ;-)

I think this is enough to get you on a nice path:

Sub a()
  Dim btn As Button
  Application.ScreenUpdating = False
  ActiveSheet.Buttons.Delete
  Dim t As Range
  For i = 2 To 6 Step 2
    Set t = ActiveSheet.Range(Cells(i, 3), Cells(i, 3))
    Set btn = ActiveSheet.Buttons.Add(t.Left, t.Top, t.Width, t.Height)
    With btn
      .OnAction = "btnS"
      .Caption = "Btn " & i
      .Name = "Btn" & i
    End With
  Next i
  Application.ScreenUpdating = True
End Sub

Sub btnS()
 MsgBox Application.Caller
End Sub

It creates the buttons and binds them to butnS(). In the btnS() sub, you should show your dialog, etc.

You can delay your code using setTimeout to execute after click

function changeLink(){
    setTimeout(function() {
        var link = document.getElementById("mylink");
        link.setAttribute('href', "http://facebook.com");
        document.getElementById("mylink").innerHTML = "facebook";
    }, 100);
}

There is no hostname verification in standard Java SSL sockets or indeed SSL, so that's why you can't set it at that level. Hostname verification is part of HTTPS (RFC 2818): that's why it manifests itself as javax.net.ssl.HostnameVerifier, which is applied to an HttpsURLConnection.

shape() consists of array having two arguments rows and columns.

if you search shape[0] then it will gave you the number of rows. shape[1] will gave you number of columns.

I finally found this link:

https://blogs.perficient.com/microsoft/2011/06/powershell-count-property-returns-nothing/

Well, it turns out that this is a quirk caused precisely because there was only one file in the directory. Some searching revealed that in this case, PowerShell returns a scalar object instead of an array. This object doesn’t have a count property, so there isn’t anything to retrieve.

The solution -- force PowerShell to return an array with the @ symbol:

Write-Host @( Get-ChildItem c:\MyFolder ).Count;

It will be fixed 64 chars, so use char(64)

Update: This got fixed in C# 7.0 with pattern matching

switch (MyObj)
    case Type1 t1:

Old answer:

It is a hole in C#'s game, no silver bullet yet.

You should google on the 'visitor pattern' but it might be a little heavy for you but still something you should know about.

Here's another take on the matter using Linq: http://community.bartdesmet.net/blogs/bart/archive/2008/03/30/a-functional-c-type-switch.aspx

Otherwise something along these lines could help

// nasty..
switch(MyObj.GetType.ToString()){
  case "Type1": etc
}

// clumsy...
if myObj  is Type1 then
if myObj is Type2 then

etc.

You can use numpy.logical_not to invert the boolean array returned by isin:

In [63]: s = pd.Series(np.arange(10.0))

In [64]: x = range(4, 8)

In [65]: mask = np.logical_not(s.isin(x))

In [66]: s[mask]
Out[66]: 
0    0
1    1
2    2
3    3
8    8
9    9

As given in the comment by Wes McKinney you can also use

s[~s.isin(x)]

I use Windows and removed all the files that were listed below and my problem was solved C:\Users{{your-username}}\AppData\Roaming\npm-cache

Any - boolean function that returns true when any of object in list satisfies condition set in function parameters. For example:

List<string> strings = LoadList();
boolean hasNonEmptyObject = strings.Any(s=>string.IsNullOrEmpty(s));

Where - function that returns list with all objects in list that satisfy condition set in function parameters. For example:

IEnumerable<string> nonEmptyStrings = strings.Where(s=> !string.IsNullOrEmpty(s));

Exists - basically the same as any but it's not generic - it's defined in List class, while Any is defined on IEnumerable interface.

Or in case you just need the value of the first seleted sell (or just one selected cell if one is selected)

TextBox1.Text = SelectedCells[0].Value.ToString();

This is a massively late reply, but I think useful for future reference. Rather than write your own math parser (although the pyparsing example above is great) you could use SymPy. I don't have a lot of experience with it, but it contains a much more powerful math engine than anyone is likely to write for a specific application and the basic expression evaluation is very easy:

>>> import sympy
>>> x, y, z = sympy.symbols('x y z')
>>> sympy.sympify("x**3 + sin(y)").evalf(subs={x:1, y:-3})
0.858879991940133

Very cool indeed! A from sympy import * brings in a lot more function support, such as trig functions, special functions, etc., but I've avoided that here to show what's coming from where.

For a period I had to extract the Media ID myself quite frequently, so I wrote my own script (very likely it's based on some of the examples here). Together with other small scripts I used frequently, I started to upload them on www.findinstaid.com for my own quick access.

I added the option to enter a username to get the media ID of the 12 most recent posts, or to enter a URL to get the media ID of a specific post.

If it's convenient, everyone can use the link (I don't have any adds or any other monetary interests in the website - I only have a referral link on the 'Audit' tab to www.auditninja.io which I do also own, but also on this site, there are no adds or monetary interests - just hobby projects).

On my execution of openssl pkcs12 -export -out cacert.pkcs12 -in testca/cacert.pem, I received the following message:

unable to load private key 140707250050712:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:701:Expecting: ANY PRIVATE KEY`

Got this solved by providing the key file along with the command. The switch is -inkey inkeyfile.pem

You can try this with Color.FromArgb:

Random rnd = new Random();
lbl.ForeColor = Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255));

First, don't declare variables using var, but

public $my_value;

Then you can access it using

$this->my_value;

and not

$this->$my_value;

In my case, I had a mix and match error between projects created in VS2015 and VS2017. In my .vcxproj file, there's this section called PropertyGroup Label="Globals">. I had a section for TargetPlatformVersion=10.0.15063.0. When I removed the TargetPlatformVersion, that solved the problem.

Sorry I can't copy and paste the block here, but stackoverflows coding format did not allow that.

var timeArr = moment().format('x');

returns the Unix Millisecond Timestamp as per the format() documentation.

Just different names for what is really ECMAScript. John Resig has a good explanation.

Here's the full version breakdown:

• IE 6-7 support JScript 5 (which is equivalent to ECMAScript 3, JavaScript 1.5)
• IE 8 supports JScript 6 (which is equivalent to ECMAScript 3, JavaScript 1.5 - more bug fixes over JScript 5)
• Firefox 1.0 supports JavaScript 1.5 (ECMAScript 3 equivalent)
• Firefox 1.5 supports JavaScript 1.6 (1.5 + Array Extras + E4X + misc.)
• Firefox 2.0 supports JavaScript 1.7 (1.6 + Generator + Iterators + let + misc.)
• Firefox 3.0 supports JavaScript 1.8 (1.7 + Generator Expressions + Expression Closures + misc.)
• The next version of Firefox will support JavaScript 1.9 (1.8 + To be determined)
• Opera supports a language that is equivalent to ECMAScript 3 + Getters and Setters + misc.
• Safari supports a language that is equivalent to ECMAScript 3 + Getters and Setters + misc.

In My case, add the package Microsoft.EntityFrameworkCore.Tools fixed problem

you can close it programmatically by calling

$('#form-dialog').dialog('close')

whenever you want.

sp_executesql is more likely to promote query plan reuse. When using sp_executesql, parameters are explicitly identified in the calling signature. This excellent article descibes this process.

To safely encrypt large files (>600MB) with openssl smime you'll have to split each file into small chunks:

# Splits large file into 500MB pieces
split -b 500M -d -a 4 INPUT_FILE_NAME input.part.

# Encrypts each piece
find -maxdepth 1 -type f -name 'input.part.*' | sort | xargs -I % openssl smime -encrypt -binary -aes-256-cbc -in % -out %.enc -outform DER PUBLIC_PEM_FILE

For the sake of information, here is how to decrypt and put all pieces together:

# Decrypts each piece
find -maxdepth 1 -type f -name 'input.part.*.enc' | sort | xargs -I % openssl smime -decrypt -in % -binary -inform DEM -inkey PRIVATE_PEM_FILE -out %.dec

# Puts all together again
find -maxdepth 1 -type f -name 'input.part.*.dec' | sort | xargs cat > RESTORED_FILE_NAME

[Using Rails 5]

Generate migration:

rails generate migration add_user_reference_to_uploads user:references

This will create the migration file:

class AddUserReferenceToUploads < ActiveRecord::Migration[5.1]
  def change
    add_reference :uploads, :user, foreign_key: true
  end
end

Now if you observe the schema file, you will see that the uploads table contains a new field. Something like: t.bigint "user_id" or t.integer "user_id".

Migrate database:

rails db:migrate

^{This answer is all about authorization and it is a complement of my previous answer about authentication}

^{Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.}

Supporting role-based authorization with the @Secured annotation

Besides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.

Create an enumeration and define the roles according to your needs:

public enum Role {
    ROLE_1,
    ROLE_2,
    ROLE_3
}

Change the @Secured name binding annotation created before to support roles:

@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
    Role[] value() default {};
}

And then annotate the resource classes and methods with @Secured to perform the authorization. The method annotations will override the class annotations:

@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {

    @GET
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response myMethod(@PathParam("id") Long id) {
        // This method is not annotated with @Secured
        // But it's declared within a class annotated with @Secured({Role.ROLE_1})
        // So it only can be executed by the users who have the ROLE_1 role
        ...
    }

    @DELETE
    @Path("{id}")    
    @Produces(MediaType.APPLICATION_JSON)
    @Secured({Role.ROLE_1, Role.ROLE_2})
    public Response myOtherMethod(@PathParam("id") Long id) {
        // This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
        // The method annotation overrides the class annotation
        // So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
        ...
    }
}

Create a filter with the AUTHORIZATION priority, which is executed after the AUTHENTICATION priority filter defined previously.

The ResourceInfo can be used to get the resource Method and resource Class that will handle the request and then extract the @Secured annotations from them:

@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        // Get the resource class which matches with the requested URL
        // Extract the roles declared by it
        Class<?> resourceClass = resourceInfo.getResourceClass();
        List<Role> classRoles = extractRoles(resourceClass);

        // Get the resource method which matches with the requested URL
        // Extract the roles declared by it
        Method resourceMethod = resourceInfo.getResourceMethod();
        List<Role> methodRoles = extractRoles(resourceMethod);

        try {

            // Check if the user is allowed to execute the method
            // The method annotations override the class annotations
            if (methodRoles.isEmpty()) {
                checkPermissions(classRoles);
            } else {
                checkPermissions(methodRoles);
            }

        } catch (Exception e) {
            requestContext.abortWith(
                Response.status(Response.Status.FORBIDDEN).build());
        }
    }

    // Extract the roles from the annotated element
    private List<Role> extractRoles(AnnotatedElement annotatedElement) {
        if (annotatedElement == null) {
            return new ArrayList<Role>();
        } else {
            Secured secured = annotatedElement.getAnnotation(Secured.class);
            if (secured == null) {
                return new ArrayList<Role>();
            } else {
                Role[] allowedRoles = secured.value();
                return Arrays.asList(allowedRoles);
            }
        }
    }

    private void checkPermissions(List<Role> allowedRoles) throws Exception {
        // Check if the user contains one of the allowed roles
        // Throw an Exception if the user has not permission to execute the method
    }
}

If the user has no permission to execute the operation, the request is aborted with a 403 (Forbidden).

To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext (which should be already set in the ContainerRequestContext) or inject it using CDI, depending on the approach you go for.

If a @Secured annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.

Supporting role-based authorization with JSR-250 annotations

Alternatively to defining the roles in the @Secured annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed, @PermitAll and @DenyAll.

JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:

• @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll on the class.
• @RolesAllowed on the method takes precedence over @PermitAll on the class.
• @PermitAll on the method takes precedence over @RolesAllowed on the class.
• @DenyAll can't be attached to classes.
• @RolesAllowed on the class takes precedence over @PermitAll on the class.

So an authorization filter that checks JSR-250 annotations could be like:

@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        Method method = resourceInfo.getResourceMethod();

        // @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
        if (method.isAnnotationPresent(DenyAll.class)) {
            refuseRequest();
        }

        // @RolesAllowed on the method takes precedence over @PermitAll
        RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
            return;
        }

        // @PermitAll on the method takes precedence over @RolesAllowed on the class
        if (method.isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // @DenyAll can't be attached to classes

        // @RolesAllowed on the class takes precedence over @PermitAll on the class
        rolesAllowed = 
            resourceInfo.getResourceClass().getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
        }

        // @PermitAll on the class
        if (resourceInfo.getResourceClass().isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // Authentication is required for non-annotated methods
        if (!isAuthenticated(requestContext)) {
            refuseRequest();
        }
    }

    /**
     * Perform authorization based on roles.
     *
     * @param rolesAllowed
     * @param requestContext
     */
    private void performAuthorization(String[] rolesAllowed, 
                                      ContainerRequestContext requestContext) {

        if (rolesAllowed.length > 0 && !isAuthenticated(requestContext)) {
            refuseRequest();
        }

        for (final String role : rolesAllowed) {
            if (requestContext.getSecurityContext().isUserInRole(role)) {
                return;
            }
        }

        refuseRequest();
    }

    /**
     * Check if the user is authenticated.
     *
     * @param requestContext
     * @return
     */
    private boolean isAuthenticated(final ContainerRequestContext requestContext) {
        // Return true if the user is authenticated or false otherwise
        // An implementation could be like:
        // return requestContext.getSecurityContext().getUserPrincipal() != null;
    }

    /**
     * Refuse the request.
     */
    private void refuseRequest() {
        throw new AccessDeniedException(
            "You don't have permissions to perform this action.");
    }
}

^{Note: The above implementation is based on the Jersey RolesAllowedDynamicFeature. If you use Jersey, you don't need to write your own filter, just use the existing implementation.}

The advantage to a single CSS file is transfer efficiency. Each HTTP request means a HTTP header response for each file requested, and that takes bandwidth.

I serve my CSS as a PHP file with the "text/css" mime type in the HTTP header. This way I can have multiple CSS files on the server side and use PHP includes to push them into a single file when requested by the user. Every modern browser receives the .php file with the CSS code and processes it as a .css file.

Persist and merge are for two different purposes (they aren't alternatives at all).

(edited to expand differences information)

persist:

• Insert a new register to the database
• Attach the object to the entity manager.

merge:

• Find an attached object with the same id and update it.
• If exists update and return the already attached object.
• If doesn't exist insert the new register to the database.

persist() efficiency:

• It could be more efficient for inserting a new register to a database than merge().
• It doesn't duplicates the original object.

persist() semantics:

• It makes sure that you are inserting and not updating by mistake.

Example:

{
    AnyEntity newEntity;
    AnyEntity nonAttachedEntity;
    AnyEntity attachedEntity;

    // Create a new entity and persist it        
    newEntity = new AnyEntity();
    em.persist(newEntity);

    // Save 1 to the database at next flush
    newEntity.setValue(1);

    // Create a new entity with the same Id than the persisted one.
    AnyEntity nonAttachedEntity = new AnyEntity();
    nonAttachedEntity.setId(newEntity.getId());

    // Save 2 to the database at next flush instead of 1!!!
    nonAttachedEntity.setValue(2);
    attachedEntity = em.merge(nonAttachedEntity);

    // This condition returns true
    // merge has found the already attached object (newEntity) and returns it.
    if(attachedEntity==newEntity) {
            System.out.print("They are the same object!");
    }

    // Set 3 to value
    attachedEntity.setValue(3);
    // Really, now both are the same object. Prints 3
    System.out.println(newEntity.getValue());

    // Modify the un attached object has no effect to the entity manager
    // nor to the other objects
    nonAttachedEntity.setValue(42);
}

This way only exists 1 attached object for any register in the entity manager.

merge() for an entity with an id is something like:

AnyEntity myMerge(AnyEntity entityToSave) {
    AnyEntity attached = em.find(AnyEntity.class, entityToSave.getId());
    if(attached==null) {
            attached = new AnyEntity();
            em.persist(attached);
    }
    BeanUtils.copyProperties(attached, entityToSave);

    return attached;
}

Although if connected to MySQL merge() could be as efficient as persist() using a call to INSERT with ON DUPLICATE KEY UPDATE option, JPA is a very high level programming and you can't assume this is going to be the case everywhere.

If you want to cherry-pick multiple commits for a given file until you reach a given commit, then use the following.

# Directory from which to cherry-pick
GIT_DIR=...
# Pick changes only for this file
FILE_PATH=...
# Apply changes from this commit
FIST_COMMIT=master
# Apply changes until you reach this commit
LAST_COMMIT=...

for sha in $(git --git-dir=$GIT_DIR log --reverse --topo-order --format=%H $LAST_COMMIT_SHA..master -- $FILE_PATH ) ; do 
  git --git-dir=$GIT_DIR  format-patch -k -1 --stdout $sha -- $FILE_PATH | 
    git am -3 -k
done

You can't do it the way you wanted.

Use ArrayList instead:

List<String> a = new ArrayList<String>();
a.add("kk");
a.add("pp");

And then you can have an array again by using toArray:

String[] myArray = new String[a.size()];
a.toArray(myArray);

You simply need to start mysql and feed it with the content of db.sql:

mysql -u user -p < db.sql

You are using Object, and you don't have an associative array to begin with. With an associative array, adding and removing items goes like this:

    Array.prototype.contains = function(obj)
    {
        var i = this.length;
        while (i--)
        {
            if (this[i] === obj)
            {
                return true;
            }
        }
        return false;
    }


    Array.prototype.add = function(key, value)
    {
        if(this.contains(key))
            this[key] = value;
        else
        {
            this.push(key);
            this[key] = value;
        }
    }


    Array.prototype.remove = function(key)
    {
        for(var i = 0; i < this.length; ++i)
        {
            if(this[i] == key)
            {
                this.splice(i, 1);
                return;
            }
        }
    }



    // Read a page's GET URL variables and return them as an associative array.
    function getUrlVars()
    {
        var vars = [], hash;
        var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');

        for(var i = 0; i < hashes.length; i++)
        {
            hash = hashes[i].split('=');
            vars.push(hash[0]);
            vars[hash[0]] = hash[1];
        }

        return vars;
    }


    function ForwardAndHideVariables() {
        var dictParameters = getUrlVars();

        dictParameters.add("mno", "pqr");
        dictParameters.add("mno", "stfu");

        dictParameters.remove("mno");


        for(var i = 0; i < dictParameters.length; i++)
        {
            var key = dictParameters[i];
            var value = dictParameters[key];
            alert(key + "=" + value);
        }
        // And now forward with HTTP-POST
        aa_post_to_url("Default.aspx", dictParameters);
    }


    function aa_post_to_url(path, params, method) {
        method = method || "post";

        var form = document.createElement("form");

        // Move the submit function to another variable
        // so that it doesn't get written over if a parameter name is 'submit'
        form._submit_function_ = form.submit;

        form.setAttribute("method", method);
        form.setAttribute("action", path);

        for(var i = 0; i < params.length; i++)
        {
            var key = params[i];

            var hiddenField = document.createElement("input");
            hiddenField.setAttribute("type", "hidden");
            hiddenField.setAttribute("name", key);
            hiddenField.setAttribute("value", params[key]);

            form.appendChild(hiddenField);
        }

        document.body.appendChild(form);
        form._submit_function_(); // Call the renamed function
    }
