A SELECT INTO statement will throw an error if it returns anything other than 1 row. If it returns 0 rows, you'll get a no_data_found exception. If it returns more than 1 row, you'll get a too_many_rows exception. Unless you know that there will always be exactly 1 employee with a salary greater than 3000, you do not want a SELECT INTO statement here.

Most likely, you want to use a cursor to iterate over (potentially) multiple rows of data (I'm also assuming that you intended to do a proper join between the two tables rather than doing a Cartesian product so I'm assuming that there is a departmentID column in both tables)

BEGIN
  FOR rec IN (SELECT EMPLOYEE.EMPID, 
                     EMPLOYEE.ENAME, 
                     EMPLOYEE.DESIGNATION, 
                     EMPLOYEE.SALARY,  
                     DEPARTMENT.DEPT_NAME 
                FROM EMPLOYEE, 
                     DEPARTMENT 
               WHERE employee.departmentID = department.departmentID
                 AND EMPLOYEE.SALARY > 3000)
  LOOP
    DBMS_OUTPUT.PUT_LINE ('Employee Nnumber: ' || rec.EMPID);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Name: ' || rec.ENAME);
    DBMS_OUTPUT.PUT_LINE ('---------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Designation: ' || rec.DESIGNATION);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Salary: ' || rec.SALARY);
    DBMS_OUTPUT.PUT_LINE ('----------------------------------------------------');
    DBMS_OUTPUT.PUT_LINE ('Employee Department: ' || rec.DEPT_NAME);
  END LOOP;
END;

I'm assuming that you are just learning PL/SQL as well. In real code, you'd never use dbms_output like this and would not depend on anyone seeing data that you write to the dbms_output buffer.

If you want to edit some complex javascript I suggest you use JsFiddle. Alternatively, for smaller pieces of javascript you can just run it through your browser URL bar, here's an example:

javascript:alert("hello world");

And, as it was already suggested both Firebug and Chrome developer tools have Javascript console, in which you can type in your javascript to execute. So do Internet Explorer 8+, Opera, Safari and potentially other modern browsers.

I got this work good for me.

The statement about CMake being a "build generator" is a common misconception.

It's not technically wrong; it just describes HOW it works, but not WHAT it does.

In the context of the question, they do the same thing: take a bunch of C/C++ files and turn them into a binary.

So, what is the real difference?

• CMake is much more high-level. It's tailored to compile C++, for which you write much less build code, but can be also used for general purpose build. make has some built-in C/C++ rules as well, but they are useless at best.

• CMake does a two-step build: it generates a low-level build script in ninja or make or many other generators, and then you run it. All the shell script pieces that are normally piled into Makefile are only executed at the generation stage. Thus, CMake build can be orders of magnitude faster.

• The grammar of CMake is much easier to support for external tools than make's.

• Once make builds an artifact, it forgets how it was built. What sources it was built from, what compiler flags? CMake tracks it, make leaves it up to you. If one of library sources was removed since the previous version of Makefile, make won't rebuild it.

• Modern CMake (starting with version 3.something) works in terms of dependencies between "targets". A target is still a single output file, but it can have transitive ("public"/"interface" in CMake terms) dependencies. These transitive dependencies can be exposed to or hidden from the dependent packages. CMake will manage directories for you. With make, you're stuck on a file-by-file and manage-directories-by-hand level.

You could code up something in make using intermediate files to cover the last two gaps, but you're on your own. make does contain a Turing complete language (even two, sometimes three counting Guile); the first two are horrible and the Guile is practically never used.

To be honest, this is what CMake and make have in common -- their languages are pretty horrible. Here's what comes to mind:

• They have no user-defined types;
• CMake has three data types: string, list, and a target with properties. make has one: string;
• you normally pass arguments to functions by setting global variables.
  • This is partially dealt with in modern CMake - you can set a target's properties: set_property(TARGET helloworld APPEND PROPERTY INCLUDE_DIRECTORIES "${CMAKE_CURRENT_SOURCE_DIR}");
• referring to an undefined variable is silently ignored by default;

When you are trying to prevent XSS, it's important to think of the context. As an example how and what to escape is very different if you are ouputting data inside a variable in a javascript snippet as opposed to outputting data in an HTML tag or an HTML attribute.

I have an example of this here: http://erlend.oftedal.no/blog/?blogid=91

Also checkout the OWASP XSS Prevention Cheat Sheet: http://www.owasp.org/index.php/XSS_%28Cross_Site_Scripting%29_Prevention_Cheat_Sheet

So the short answer is, make sure you escape output like suggested by Tendayi Mawushe, but take special care when you are outputting data in HTML attributes or javascript.

You can't initialize a and b in B because they are not members of B. They are members of A, therefore only A can initialize them. You can make them public, then do assignment in B, but that is not a recommended option since it would destroy encapsulation. Instead, create a constructor in A to allow B (or any subclass of A) to initialize them:

class A 
{
protected:
    A(int a, int b) : a(a), b(b) {} // Accessible to derived classes
    // Change "protected" to "public" to allow others to instantiate A.
private:
    int a, b; // Keep these variables private in A
};

class B : public A 
{
public:
    B() : A(0, 0) // Calls A's constructor, initializing a and b in A to 0.
    {
    } 
};

If you have arrived at this question because IntelliSense has stopped working properly and you are hoping to force it to show you what you need, then most likely none of these solutions are going to work.

Closing and restarting Visual Studio should fix the problem.

Just one line and you are done (make sure mysql command is available as global or just go to mysql installation folder and enter into bin folder)

mysql -u database_user_name -p -D database_name < complete_file_path_with_file_name_and_extension 

Here

• u stands for User
• p stands for Password
• D stands for Database

---DON'T FORGET TO ADD < SIGN AFTER DATABASE NAME---

Complete file path with name and extension can be like

c:\folder_name\"folder name"\sql_file.sql

---IF YOUR FOLDER AND FILE NAME CONTAINS SPACE THAN BIND THEM USING DOUBLE QUOTE---

Tip and Note: You can write your password after -p but this is not recommended because it will show to others who are watching your screen at that time, if you don't write there it will ask you when you will execute command by pressing enter.

Here's a solution that works with fixed backgrounds, if you have a fixed background and you have some overlayed elements and you need blured backgrounds for them, this solution works:

Image we have this simple HTML:

<body> <!-- or any wrapper -->
   <div class="content">Some Texts</div>
</body>

A fixed background for <body> or the wrapper element:

body {
  background-image: url(http://placeimg.com/640/360/any);
  background-size: cover;
  background-repeat: no-repeat;
  background-attachment: fixed;
}

And here for example we have a overlayed element with a white transparent background:

.content {
  background-color: rgba(255, 255, 255, 0.3);
  position: relative;
}

Now we need to use the exact same background image of our wrapper for our overlay elements too, i use it as a :before psuedo-class:

.content:before {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: -1;
  filter: blur(5px);
  background-image: url(http://placeimg.com/640/360/any);
  background-size: cover;
  background-repeat: no-repeat;
  background-attachment: fixed;
}

Since the fixed background works in a same way in both wrapper and overlayed elements, we have the background in exactly same scroll position of the overlayed element and we can simply blur it. Here's a working fiddle, tested in Firefox, Chrome, Opera and Edge: https://jsfiddle.net/0vL2rc4d/

NOTE: In firefox there's a bug that makes screen flicker when scrolling and there are fixed blurred backgrounds. if there's any fix, let me know

Remember that by default the return value from the input will be a string and not an integer. You cannot compare strings with booleans like <, >, =>, <= (unless you are comparing the length). Therefore your code should look like this:

number = 23
guess = int(input('Enter a number: '))  # The var guess will be an integer

if guess == number:
    print('Congratulations! You guessed it.')

elif guess != number:
    print('Wrong Number')

preferences -> mysql -> initialize database -> use legacy password encryption(instead of strong) -> entered same password

as my config.inc.php file, restarted the apache server and it worked. I was still suspicious about it so I stopped the apache and mysql server and started them again and now it's working.

You can use for loop

    int[] random_numbers = {10, 30, 44, 21, 51, 21, 61, 24, 14}
    int array_length = random_numbers.Length;
    for (int i = 0; i < array_length; i++){
        if(i == array_length - 1){
              Console.Write($"{random_numbers[i]}\n");
        } else{
              Console.Write($"{random_numbers[i]}, ");
         }
     }

There are a couple options you can use:

1. You could try using the string "(DATETIME('now'))" instead.
2. Insert the datetime yourself, ie with System.currentTimeMillis()
3. When creating the SQLite table, specify a default value for the created_date column as the current date time.
4. Use SQLiteDatabase.execSQL to insert directly.

Flat and simple config without rewrite, can work in some cases:

location / {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME /home/webuser/site/index.php;
}

Here is an example of implementing stack in java (Array Based implementation):

public class MyStack extends Throwable{

/**
 * 
 */
private static final long serialVersionUID = -4433344892390700337L;

protected static int top = -1;
protected static int capacity;
protected static int size;

public int stackDatas[] = null;

public MyStack(){
    stackDatas = new int[10];
    capacity = stackDatas.length;
}

public static int size(){

    if(top < 0){
        size = top + 1;
        return size;
    }
    size = top+1;
    return size; 
}

public void push(int data){
    if(capacity == size()){
        System.out.println("no memory");
    }else{
        stackDatas[++top] = data;
    }
}

public boolean topData(){
    if(top < 0){
        return true;
    }else{
        System.out.println(stackDatas[top]);
        return false;
    }
}

public void pop(){
    if(top < 0){
        System.out.println("stack is empty");
    }else{
        int temp = stackDatas[top];
        stackDatas = ArrayUtils.remove(stackDatas, top--);
        System.out.println("poped data---> "+temp);
    }
}

public String toString(){
    String result = "[";

    if(top<0){
        return "[]";
    }else{


    for(int i = 0; i< size(); i++){
        result = result + stackDatas[i] +",";
    }
    }

    return result.substring(0, result.lastIndexOf(",")) +"]";
 }
}

calling MyStack:

    public class CallingMyStack {

public static MyStack ms;

public static void main(String[] args) {

    ms = new MyStack();
    ms.push(1);
    ms.push(2);
    ms.push(3);
    ms.push(4);
    ms.push(5);
    ms.push(6);
    ms.push(7);
    ms.push(8);
    ms.push(9);
    ms.push(10);
    System.out.println("size: "+MyStack.size());
    System.out.println("List---> "+ms);
    System.out.println("----------");
    ms.pop();
    ms.pop();
    ms.pop();
    ms.pop();
    System.out.println("List---> "+ms);
    System.out.println("size: "+MyStack.size());

 }
}

output:

size: 10
List---> [1,2,3,4,5,6,7,8,9,10]
----------
poped data---> 10
poped data---> 9
poped data---> 8
poped data---> 7
List---> [1,2,3,4,5,6]
size: 6

Swift 3 & 4

Swift 3, and now Swift 4, have replaced many "stringly-typed" APIs with struct "wrapper types", as is the case with NotificationCenter. Notifications are now identified by a struct Notfication.Name rather than by String. For more details see the now legacy Migrating to Swift 3 guide

Swift 2.2 usage:

// Define identifier
let notificationIdentifier: String = "NotificationIdentifier"

// Register to receive notification
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification(_:)), name: notificationIdentifier, object: nil)

// Post a notification
NSNotificationCenter.defaultCenter().postNotificationName(notificationIdentifier, object: nil)

Swift 3 & 4 usage:

// Define identifier
let notificationName = Notification.Name("NotificationIdentifier")

// Register to receive notification
NotificationCenter.default.addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification), name: notificationName, object: nil)

// Post notification
NotificationCenter.default.post(name: notificationName, object: nil)

// Stop listening notification
NotificationCenter.default.removeObserver(self, name: notificationName, object: nil)

All of the system notification types are now defined as static constants on Notification.Name; i.e. .UIApplicationDidFinishLaunching, .UITextFieldTextDidChange, etc.

You can extend Notification.Name with your own custom notifications in order to stay consistent with the system notifications:

// Definition:
extension Notification.Name {
    static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}

// Usage:
NotificationCenter.default.post(name: .yourCustomNotificationName, object: nil)

Swift 4.2 usage:

Same as Swift 4, except now system notifications names are part of UIApplication. So in order to stay consistent with the system notifications you can extend UIApplication with your own custom notifications instead of Notification.Name :

// Definition:
UIApplication {
    public static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}

// Usage:
NotificationCenter.default.post(name: UIApplication.yourCustomNotificationName, object: nil)

Here's a practical example (build a dataset from your current location):

$ds = new-object System.Data.DataSet
$ds.Tables.Add("tblTest")
[void]$ds.Tables["tblTest"].Columns.Add("Name",[string])
[void]$ds.Tables["tblTest"].Columns.Add("Path",[string])

dir | foreach {
    $dr = $ds.Tables["tblTest"].NewRow()
    $dr["Name"] = $_.name
    $dr["Path"] = $_.fullname
    $ds.Tables["tblTest"].Rows.Add($dr)
}


$ds.Tables["tblTest"]

$ds.Tables["tblTest"] is an object that you can manipulate just like any other Powershell object:

$ds.Tables["tblTest"] | foreach {
    write-host 'Name value is : $_.name
    write-host 'Path value is : $_.path
}

You should use some form of the String#equals(Object) method. However, there is some subtlety in how you should do it:

If you have a string literal then you should use it like this:

"Hello".equals(someString);

This is because the string literal "Hello" can never be null, so you will never run into a NullPointerException.

If you have a string and another object then you should use:

myString.equals(myObject);

You can make sure you are actually getting string equality by doing this. For all you know, myObject could be of a class that always returns true in its equals method!

Start with the object less likely to be null because this:

String foo = null;
String bar = "hello";
foo.equals(bar);

will throw a NullPointerException, but this:

String foo = null;
String bar = "hello";
bar.equals(foo);

will not. String#equals(Object) will correctly handle the case when its parameter is null, so you only need to worry about the object you are dereferencing--the first object.

Your idea to use enumerate() was correct.

indices = []
for i, elem in enumerate(mylist):
    if 'aa' in elem:
        indices.append(i)

Alternatively, as a list comprehension:

indices = [i for i, elem in enumerate(mylist) if 'aa' in elem]

SELECT e1.emp_id, e1.emp_name, e1.mgr_id, e2.emp_name as manager_name

FROM employee e1

JOIN employee e2

ON e1.mgr_id = e2.emp_id

ORDER BY e1.emp_id

*Here is the link to SQL Fiddle with a working example. http://www.sqlfiddle.com/#!17/392b5/9

It's simple I think you can just say

#define NAME JACK    
#if NAME == queen

From @K3---rnc response (the best for me) I've added a small modifications to get an OrderedDict from an XML text (some times order matters):

def etree_to_ordereddict(t):
d = OrderedDict()
d[t.tag] = OrderedDict() if t.attrib else None
children = list(t)
if children:
    dd = OrderedDict()
    for dc in map(etree_to_ordereddict, children):
        for k, v in dc.iteritems():
            if k not in dd:
                dd[k] = list()
            dd[k].append(v)
    d = OrderedDict()
    d[t.tag] = OrderedDict()
    for k, v in dd.iteritems():
        if len(v) == 1:
            d[t.tag][k] = v[0]
        else:
            d[t.tag][k] = v
if t.attrib:
    d[t.tag].update(('@' + k, v) for k, v in t.attrib.iteritems())
if t.text:
    text = t.text.strip()
    if children or t.attrib:
        if text:
            d[t.tag]['#text'] = text
    else:
        d[t.tag] = text
return d

Following @K3---rnc example, you can use it:

from xml.etree import cElementTree as ET
e = ET.XML('''
<root>
  <e />
  <e>text</e>
  <e name="value" />
  <e name="value">text</e>
  <e> <a>text</a> <b>text</b> </e>
  <e> <a>text</a> <a>text</a> </e>
  <e> text <a>text</a> </e>
</root>
''')

from pprint import pprint
pprint(etree_to_ordereddict(e))

Hope it helps ;)

Would these work?

plt.scatter(np.random.randn(100), np.random.randn(100), facecolors='none')

or using plot()

plt.plot(np.random.randn(100), np.random.randn(100), 'o', mfc='none')

Here are three ways:

1. Fake a real object:

   class convert
   {
       public $varible;
   
       public function __construct($array)
       {
           $this = $array;
       }
   
       public static function toObject($array)
       {
           $array = new convert($array);
           return $array;
       }
   }
   

2. Convert the array into an object by casting it to an object:

   $array = array(
       // ...
   );
   $object = (object) $array;
   

3. Manually convert the array into an object:

   $object = object;
   foreach ($arr as $key => $value) {
       $object->{$key} = $value;
   }
   

Here's a couple of suggestions:

Use date_range for the index:

import datetime
import pandas as pd
import numpy as np

todays_date = datetime.datetime.now().date()
index = pd.date_range(todays_date-datetime.timedelta(10), periods=10, freq='D')

columns = ['A','B', 'C']

Note: we could create an empty DataFrame (with NaNs) simply by writing:

df_ = pd.DataFrame(index=index, columns=columns)
df_ = df_.fillna(0) # with 0s rather than NaNs

To do these type of calculations for the data, use a numpy array:

data = np.array([np.arange(10)]*3).T

Hence we can create the DataFrame:

In [10]: df = pd.DataFrame(data, index=index, columns=columns)

In [11]: df
Out[11]: 
            A  B  C
2012-11-29  0  0  0
2012-11-30  1  1  1
2012-12-01  2  2  2
2012-12-02  3  3  3
2012-12-03  4  4  4
2012-12-04  5  5  5
2012-12-05  6  6  6
2012-12-06  7  7  7
2012-12-07  8  8  8
2012-12-08  9  9  9

event.preventDefault(); Stops the default action of an element from happening.

event.stopPropagation(); Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.

For example, if there is a link with a click method attached inside of a DIV or FORM that also has a click method attached, it will prevent the DIV or FORM click method from firing.

If there's always a single CRLF, then:

myString = myString.Substring(0, myString.Length - 2);

If it may or may not have it, then:

Regex re = new Regex("\r\n$");
re.Replace(myString, "");

Both of these (by design), will remove at most a single CRLF. Cache the regex for performance.

An easier way to clear a screen while in python is to use Ctrl + L though it works for the shell as well as other programs.

Yes, SimpleSort, in theory it runs in O(-1) however this is equivalent to O(...9999) which is in turn equivalent to O(∞ - 1), which as it happens is also equivalent to O(∞). Here is my sample implementation:

/* element sizes are uneeded, they are assumed */
void
simplesort (const void* begin, const void* end)
{
  for (;;);
}

Dim dr As DataRow()


dr = dt.Select("A="& a & "and B="& b & "and C=" & c,"A",DataViewRowState.CurrentRows)

Where A,B,C are the column names where second parameter is for sort expression

Ideally you shouldn't be splitting strings in T-SQL at all.

Barring that change, on older versions before SQL Server 2016, create a split function:

CREATE FUNCTION dbo.SplitStrings
(
    @List      nvarchar(max), 
    @Delimiter nvarchar(2)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
  RETURN ( WITH x(x) AS
    (
      SELECT CONVERT(xml, N'<root><i>' 
        + REPLACE(@List, @Delimiter, N'</i><i>') 
        + N'</i></root>')
    )
    SELECT Item = LTRIM(RTRIM(i.i.value(N'.',N'nvarchar(max)')))
      FROM x CROSS APPLY x.nodes(N'//root/i') AS i(i)
  );
GO

Now you can say:

DECLARE @Values varchar(1000);

SET @Values = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN dbo.SplitStrings(@Values, ',') AS s
    ON s.Item = foo.myField;

On SQL Server 2016 or above (or Azure SQL Database), it is much simpler and more efficient, however you do have to manually apply LTRIM() to take away any leading spaces:

DECLARE @Values varchar(1000) = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN STRING_SPLIT(@Values, ',') AS s
    ON LTRIM(s.value) = foo.myField;

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

If you find yourself doing things like this regularly it may be worth investigating the object-oriented interface to matplotlib. In your case:

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(5)
y = np.exp(x)
fig1, ax1 = plt.subplots()
ax1.plot(x, y)
ax1.set_title("Axis 1 title")
ax1.set_xlabel("X-label for axis 1")

z = np.sin(x)
fig2, (ax2, ax3) = plt.subplots(nrows=2, ncols=1) # two axes on figure
ax2.plot(x, z)
ax3.plot(x, -z)

w = np.cos(x)
ax1.plot(x, w) # can continue plotting on the first axis

It is a little more verbose but it's much clearer and easier to keep track of, especially with several figures each with multiple subplots.

try like below...

CASE 
WHEN currate.currentrate is null THEN 1
ELSE currate.currentrate
END as currentrate

Try doing this:

 textValue= textValue.replaceAll("\n", "");
 textValue= textValue.replaceAll("\t", "");
 textValue= textValue.replaceAll("\\n", "");
 textValue= textValue.replaceAll("\\t", "");
 textValue= textValue.replaceAll("\r", "");
 textValue= textValue.replaceAll("\\r", "");
 textValue= textValue.replaceAll("\r\n", "");
 textValue= textValue.replaceAll("\\r\\n", "");

ok to hide back arrow use

getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setHomeButtonEnabled(false);

then find hamburger icon in web ->hamburger

and finally, set this drawable in your project with action bar method:

getSupportActionBar().setLogo(R.drawable.hamburger_icon);

Your XIB file is probably outside your project folder. This leads to not showing up the Target Inspector. However, moving the XIB file into your project folder should fix it.

Option #1: Try invalidateOptionsMenu(). I don't know if this will force an immediate redraw of the action bar or not.

Option #2: See if getActionView() returns anything for the affected MenuItem. It is possible that showAsAction simply automatically creates action views for you. If so, you can presumably enable/disable that View.

I can't seem to find a way to get the currently set Menu to manipulate it except for in onPrepareOptionMenu.

You can hang onto the Menu object you were handed in onCreateOptionsMenu(). Quoting the docs:

You can safely hold on to menu (and any items created from it), making modifications to it as desired, until the next time onCreateOptionsMenu() is called.

Click above in the red circle. Your folder will appear in Solution Explorer.

Right click on your folder -> Include in project.

The only way to retrieve the correct value in your context is to run $.ajax() function synchronously (what actually contradicts to main AJAX idea). There is the special configuration attribute async you should set to false. In that case the main scope which actually contains $.ajax() function call is paused until the synchronous function is done, so, the return is called only after $.ajax().

function doSomething() {
    var status = 0;
    $.ajax({
        url: 'action.php',
        type: 'POST',
        data: dataString,
        async: false,
        success: function (txtBack) {
            if (txtBack == 1)
                status = 1;
        }
    });

    return status;
}

var response = doSomething();

if you want to get "terse" :)

List<string>GlobalStrings = new List<string>(); 

for(int x=1; x<10; x++) GlobalStrings.AddRange(new List<string> { "some value", "another value"});

You can create a large array and then copy it to a new array using System.arrayCopy

        int contentLength = 100000000;
        byte[] byteArray = new byte[contentLength];

        BufferedInputStream inputStream = new BufferedInputStream(connection.getInputStream());
        while ((bytesRead = inputStream.read()) != -1)
        {
            byteArray[count++] = (byte)bytesRead;
        }

        byte[] destArray = new byte[count];
        System.arraycopy(byteArray, 0, destArray , 0, count);

destArray will contain the information you want

I have the same problem as @KTCheek in that I need it to execute sequentially. However I figured I would try using IAsyncEnumerable (introduced in .NET Core 3) and await foreach (introduced in C# 8). Here's what I have come up with:

public static class IEnumerableExtensions {
    public static async IAsyncEnumerable<TResult> SelectAsync<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> selector) {
        foreach (var item in source) {
            yield return await selector(item);
        }
    }
}

public static class IAsyncEnumerableExtensions {
    public static async Task<List<TSource>> ToListAsync<TSource>(this IAsyncEnumerable<TSource> source) {
        var list = new List<TSource>();

        await foreach (var item in source) {
            list.Add(item);
        }

        return list;
    }
}

This can be consumed by saying:

var inputs = await events.SelectAsync(ev => ProcessEventAsync(ev)).ToListAsync();

Update: Alternatively you can add a reference to "System.Linq.Async" and then you can say:

var inputs = await events
    .ToAsyncEnumerable()
    .SelectAwait(async ev => await ProcessEventAsync(ev))
    .ToListAsync();

Alright, so I got it working by changing this

log4j.rootLogger=DebugAppender

to this

log4j.rootLogger=DEBUG, DebugAppender

Apparently you have to specify the logging level to the rootLogger first? I apologize if I wasted anyone's time.

Also, I decided to answer my own question because this wasn't a classpath issue.

timeout 5

to delay

timeout 5 >nul

to delay without asking you to press any key to cancel

I found I could improve the situation a little with CSS dedicated to Webkit (Safari, Chrome). However, I had to set a fixed width and height on the field because the font change will resize the field.

@media screen and (-webkit-min-device-pixel-ratio:0){ /* START WEBKIT */
  INPUT[type="password"]{
  font-family:Verdana,sans-serif;
  height:28px;
  font-size:19px;
  width:223px;
  padding:5px;
  }
} /* END WEBKIT */

I ran Visual Studio in Administrator mode and it worked for me :) Also, ensure that the app.config file which you are using for writing WCF configuration must be in the project where "ServiceHost" class is used, and not in actual WCF service project.

Check out these docs:

http://www.mongodb.org/display/DOCS/Starting+and+Stopping+Mongo#StartingandStoppingMongo-SendingaUnixINTorTERMsignal

If you started it in a terminal you should be ok with a ctrl + 'c' -- this will do a clean shutdown.

However, if you are using launchctl there are specific instructions for that which will vary depending on how it was installed.

If you are using Homebrew it would be launchctl stop homebrew.mxcl.mongodb

With Bootstrap 2.0 you can give your tabs the "stackable" class, which makes them stack vertically.

Heres the code that creates a Dialog which allows the user of your application to change the Look And Feel based on the user's systems. Alternatively, if you can store the wanted Look And Feel's on your application, then they could be "portable", which is the desired result.

   public void changeLookAndFeel() {

        List<String> lookAndFeelsDisplay = new ArrayList<>();
        List<String> lookAndFeelsRealNames = new ArrayList<>();

        for (LookAndFeelInfo each : UIManager.getInstalledLookAndFeels()) {
            lookAndFeelsDisplay.add(each.getName());
            lookAndFeelsRealNames.add(each.getClassName());
        }

        String changeLook = (String) JOptionPane.showInputDialog(this, "Choose Look and Feel Here:", "Select Look and Feel", JOptionPane.QUESTION_MESSAGE, null, lookAndFeelsDisplay.toArray(), null);

        if (changeLook != null) {
            for (int i = 0; i < lookAndFeelsDisplay.size(); i++) {
                if (changeLook.equals(lookAndFeelsDisplay.get(i))) {
                    try {
                        UIManager.setLookAndFeel(lookAndFeelsRealNames.get(i));
                        break;
                    }
                    catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                        err.println(ex);
                        ex.printStackTrace(System.err);
                    }
                }
            }
        }
    }

if you didnot set your activity style it shows you black background .if you want to make changes such as white background, black text of listview then it is difficult process.

ADD android:theme="@style/AppTheme" in Android Manifest.

You can use this beautiful and simple function to so so anywhere on your application.

function changeurl(url, title) {
    var new_url = '/' + url;
    window.history.pushState('data', title, new_url);
    
}

You can not only edit URL but you can update title along with it.

Quite helpful everyone.

I know its very late but I think it may help someone in resolving his issue.

In my case It was occurring because compileSdkVersion and targetSdkVersion was set to 29 while when I check my SDK Manager, It was showing that package is partially installed. Whereas SDK version 28 was completely installed. I changed my compileSdkVersion and targetSdkVersion to 28 along with support libraries.

Earlier: compileSdkVersion 29 targetSdkVersion 29 implementation 'com.android.support:appcompat-v7:29.+' implementation 'com.android.support:design:29.+'

After Modification: compileSdkVersion 28 targetSdkVersion 28 implementation 'com.android.support:appcompat-v7:28.+' implementation 'com.android.support:design:28.+'

It worked like a charm after applying these changes.

Commonly base64 it is used for images. if you like to decode an image (jpg in this example with org.apache.commons.codec.binary.Base64 package):

byte[] decoded = Base64.decodeBase64(imageJpgInBase64);
FileOutputStream fos = null;
fos = new FileOutputStream("C:\\output\\image.jpg");
fos.write(decoded);
fos.close();

In case none of the aforementioned solutions works for you, then simply do the under changes. Change this

$cfg['Servers'][$i]['host'] = '127.0.0.1';

to

$cfg['Servers'][$i]['host'] = 'localhost';

and

$cfg['Servers'][$i]['auth_type'] = 'config';

to

$cfg['Servers'][$I]['auth_type'] ='cookies';

It works in my situation, possibly works on your situation also.

Actually, on investigating this, I think all these answers are incorrect. Your question is misleading because of our level of understanding of maven. And I say our because I'm just getting introduced to maven.

In Eclipse, when you want to add a jar file to your project, normally you download the jar manually and then drop it into the lib directory. With maven, you don't do it this way. Here's what you do:

• Go to mvnrepository
• Search for the library you want to add
• Copy the dependency statement into your pom.xml
• rebuild via mvn

Now, maven will connect and download the jar along with the list of dependencies, and automatically resolve any additional dependencies that jar may have had. So if the jar also needed commons-logging, that will be downloaded as well.

window.location.hash = 'whatever';

Here's how I interpret it:

int *something[n];

Note on precedence: array subscript operator ([]) has higher priority than dereference operator (*).

So, here we will apply the [] before *, making the statement equivalent to:

int *(something[i]);

Note on how a declaration makes sense: int num means num is an int, int *ptr or int (*ptr) means, (value at ptr) is an int, which makes ptr a pointer to int.

This can be read as, (value of the (value at ith index of the something)) is an integer. So, (value at the ith index of something) is an (integer pointer), which makes the something an array of integer pointers.

In the second one,

int (*something)[n];

To make sense out of this statement, you must be familiar with this fact:

Note on pointer representation of array: somethingElse[i] is equivalent to *(somethingElse + i)

So, replacing somethingElse with (*something), we get *(*something + i), which is an integer as per declaration. So, (*something) given us an array, which makes something equivalent to (pointer to an array).

Call a custom function?

http://msdn.microsoft.com/en-us/library/ms155798.aspx

You could always put a case statement in there to handle different types of 'blank' data.

If the content is appended after .on() is called, you'll need to create a delegated event on a parent element of the loaded content. This is because event handlers are bound when .on() is called (i.e. usually on page load). If the element doesn't exist when .on() is called, the event will not be bound to it!

Because events propagate up through the DOM, we can solve this by creating a delegated event on a parent element (.parent-element in the example below) that we know exists when the page loads. Here's how:

$('.parent-element').on('click', '.mylink', function(){
  alert ("new link clicked!");
})

Mutual Exclusion. Here's the Wikipedia entry on it.

The point of a mutex is to synchronize two threads. When you have two threads attempting to access a single resource, the general pattern is to have the first block of code attempting access to set the mutex before entering the code. When the second code block attempts access, it sees that the mutex is set and waits until the first block of code is complete (and unsets the mutex), then continues.

Specific details of how this is accomplished obviously varies greatly by programming language.

In case you use Spring Test try org.springframework.test.util.ReflectionTestUtils

 ReflectionTestUtils.setField(testObject, "person", mockedPerson);

If you want to filter y active accounts add this to Harvey's code:

 UserPrincipal userPrin = new UserPrincipal(context);
 userPrin.Enabled = true;

after the first using. Then add

  searcher.QueryFilter = userPrin;

before the find all. And that should get you the active ones.

This is a very short sample of returning a single value from a procedure:

SQL:

CREATE PROCEDURE [dbo].[MakeDouble] @InpVal int AS BEGIN 
SELECT @InpVal * 2; RETURN 0; 
END

C#-code:

int inpVal = 11;
string retVal = "?";
using (var sqlCon = new SqlConnection(
    "Data Source = . ; Initial Catalog = SampleDb; Integrated Security = True;"))
{
    sqlCon.Open();
    retVal = new SqlCommand("Exec dbo.MakeDouble " + inpVal + ";", 
        sqlCon).ExecuteScalar().ToString();
    sqlCon.Close();
}
Debug.Print(inpVal + " * 2 = " + retVal); 
//> 11 * 2 = 22

I found solution in this post. In my context I wish deactivate vertical scroll when I'm scrolling horizontally inside a

Like this =>

let scrollContainer = document.getElementById('scroll-container');
document.getElementById('scroll-container').addEventListener(
    "wheel",
    (event) => {
        event.preventDefault();
        scrollContainer.scrollLeft += event.deltaY;
    },
    {
        // allow preventDefault()
        passive: false
    }
);

cleanText = strInputCode.replace(/<\/?[^>]+(>|$)/g, "");

Distilled from this website (web.achive).

This regex looks for <, an optional slash /, one or more characters that are not >, then either > or $ (the end of the line)

Examples:

'<div>Hello</div>' ==> 'Hello'
 ^^^^^     ^^^^^^
'Unterminated Tag <b' ==> 'Unterminated Tag '
                  ^^

But it is not bulletproof:

'If you are < 13 you cannot register' ==> 'If you are '
            ^^^^^^^^^^^^^^^^^^^^^^^^
'<div data="score > 42">Hello</div>' ==> ' 42">Hello'
 ^^^^^^^^^^^^^^^^^^          ^^^^^^

If someone is trying to break your application, this regex will not protect you. It should only be used if you already know the format of your input. As other knowledgable and mostly sane people have pointed out, to safely strip tags, you must use a parser.

If you do not have acccess to a convenient parser like the DOM, and you cannot trust your input to be in the right format, you may be better off using a package like sanitize-html, and also other sanitizers are available.

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

See “Herb Sutter "Back to the Basics! Essentials of Modern C++ Style”. Among other topics, he reviews the parameter passing advice that’s been given in the past, and new ideas that come in with C++11 and specifically looks at the idea of passing strings by value.

The benchmarks show that passing std::strings by value, in cases where the function will copy it in anyway, can be significantly slower!

This is because you are forcing it to always make a full copy (and then move into place), while the const& version will update the old string which may reuse the already-allocated buffer.

See his slide 27: For “set” functions, option 1 is the same as it always was. Option 2 adds an overload for rvalue reference, but this gives a combinatorial explosion if there are multiple parameters.

It is only for “sink” parameters where a string must be created (not have its existing value changed) that the pass-by-value trick is valid. That is, constructors in which the parameter directly initializes the member of the matching type.

If you want to see how deep you can go in worrying about this, watch Nicolai Josuttis’s presentation and good luck with that (“Perfect — Done!” n times after finding fault with the previous version. Ever been there?)

This is also summarized as ?F.15 in the Standard Guidelines.

I recommend:

1. The header for the .cc module you're building. (Helps ensure each header in your project doesn't have implicit dependencies on other headers in your project.)
2. C system files.
3. C++ system files.
4. Platform / OS / other header files (e.g. win32, gtk, openGL).
5. Other header files from your project.

And of course, alphabetical order within each section, where possible.

Always use forward declarations to avoid unnecessary #includes in your header files.

Use example with from the post of Szilágyi Donát.

I use two querys, one to know what roles I have, excluding connect grant:

SELECT * FROM USER_ROLE_PRIVS WHERE GRANTED_ROLE != 'CONNECT'; -- Roles of the actual Oracle Schema

Know I like to find what privileges/roles my schema/user have; examples of my roles ROLE_VIEW_PAYMENTS & ROLE_OPS_CUSTOMERS. But to find the tables/objecst of an specific role I used:

SELECT * FROM ALL_TAB_PRIVS WHERE GRANTEE='ROLE_OPS_CUSTOMERS'; -- Objects granted at role.

The owner schema for this example could be PRD_CUSTOMERS_OWNER (or the role/schema inself).

You can use clone, and then since each div has a class of car_well you can use insertAfter to insert after the last div.

$("#car2").clone().insertAfter("div.car_well:last");

1. In Notepad++ go to Plugins > Plugin manager > Show Plugin Manager then find Xml Tools plugin. Tick the box and click Install

   

2. Open XML document you want to validate and click Ctrl+Shift+Alt+M (Or use Menu if this is your preference Plugins > XML Tools > Validate Now).
   Following dialog will open:

3. Click on .... Point to XSD file and I am pretty sure you'll be able to handle things from here.

Hope this saves you some time.

EDIT: Plugin manager was not included in some versions of Notepad++ because many users didn't like commercials that it used to show. If you want to keep an older version, however still want plugin manager, you can get it on github, and install it by extracting the archive and copying contents to plugins and updates folder.
In version 7.7.1 plugin manager is back under a different guise... Plugin Admin so now you can simply update notepad++ and have it back.

For completeness, also look into the local storage capabilities & sessionStorage of HTML5. These are supported in the latest versions of all modern browsers, and are much easier to use and less fiddly than cookies.

http://www.w3.org/TR/2009/WD-webstorage-20091222/

https://www.w3.org/TR/webstorage/. (second edition)

Here are some sample code for setting and getting the values using sessionStorage and localStorage :

 // HTML5 session Storage
 sessionStorage.setItem("variableName","test");
 sessionStorage.getItem("variableName");


//HTML5 local storage 
localStorage.setItem("variableName","Text");
// Receiving the data:
localStorage.getItem("variableName");

First and foremost, for newlines, the simplest thing to do is have separate print statements, like this:

print("Hello")
print("World.")
#the parentheses allow it to work in Python 2, or 3.

To have a line break, and still only one print statement, simply use the "\n" within, as follows:

print("Hello\nWorld.")

Below, I explain spaces, instead of line breaks...

I see allot of people here using the + notation, which personally, I find ugly. Example of what I find ugly:

x=' ';
print("Hello"+10*x+"world"); 

The example above is currently, as I type this the top up-voted answer. The programmer is obviously coming into Python from PHP as the ";" syntax at the end of every line, well simple isn't needed. The only reason it doesn't through an error in Python is because semicolons CAN be used in Python, really should only be used when you are trying to place two lines on one, for aesthetic reasons. You shouldn't place these at the end of every line in Python, as it only increases file-size.

Personally, I prefer to use %s notation. In Python 2.7, which I prefer, you don't need the parentheses, "(" and ")". However, you should include them anyways, so your script won't through errors, in Python 3.x, and will run in either.

Let's say you wanted your space to be 8 spaces, So what I would do would be the following in Python > 3.x

print("Hello", "World.",  sep=' '*8, end="\n")
# you don't need to specify end, if you don't want to, but I wanted you to know it was also an option
#if you wanted to have an 8 space prefix, and did not wish to use tabs for some reason, you could do the following.
print("%sHello World." % (' '*8))

The above method will work in Python 2.x as well, but you cannot add the "sep" and "end" arguments, those have to be done manually in Python < 3.

Therefore, to have an 8 space prefix, with a 4 space separator, the syntax which would work in Python 2, or 3 would be:

print("%sHello%sWorld." % (' '*8, ' '*4))

I hope this helps.

P.S. You also could do the following.

>>> prefix=' '*8
>>> sep=' '*2
>>> print("%sHello%sWorld." % (prefix, sep))
    Hello  World.

Java strings have .startsWith() and .contains() methods which will get you most of the way. For anything more complicated you'd have to use regex or write your own method.

Thanks to AddRange:

Example:

public class Person
{ 
    private string Name;
    private string FirstName;

    public Person(string name, string firstname) => (Name, FirstName) = (name, firstname);
}

To add multiple Person to a List<>:

List<Person> listofPersons = new List<Person>();
listofPersons.AddRange(new List<Person>
{
    new Person("John1", "Doe" ),
    new Person("John2", "Doe" ),
    new Person("John3", "Doe" ),
 });

You'll have to convert it from dps to pixels using the display scale factor.

final float scale = getContext().getResources().getDisplayMetrics().density;
int pixels = (int) (dps * scale + 0.5f);

shell_exec - Execute command via shell and return the complete output as a string

exec - Execute an external program.

The difference is that with shell_exec you get output as a return value.

Saty described the differences between them. For your practice, you can use datetime in order to keep the output of NOW().

For example:

CREATE TABLE Orders
(
  OrderId int NOT NULL,
  ProductName varchar(50) NOT NULL,
  OrderDate datetime NOT NULL DEFAULT NOW(),
  PRIMARY KEY (OrderId)
)

You can read more at w3schools.

When I need 01 instead of 1, the following worked for me:

$number = 1;
$number = str_pad($number, 2, '0', STR_PAD_LEFT);

I've been using a navigation controller. When I want to either descend to another level of data or show my custom view I use the following:

[self.navigationController pushViewController:<view> animated:<BOOL>];

When I do this, I do get the viewWillAppear function to fire. I suppose this qualifies as "indirect" because I'm not calling the actual addSubView method myself. I don't know if this is 100% applicable to your application since I can't tell if you're using a navigation controller, but maybe it will provide a clue.

Then here http://docs.python.org/library/stdtypes.html#mapping-types-dict

Then here http://docs.python.org/library/stdtypes.html#dict.get

characters.get( key, default )

key is a character

default is 0

If the character is in the dictionary, characters, you get the dictionary object.

If not, you get 0.

Syntax:

get(key[, default])

Return the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError.

For Angular Version 11+

Configuration

The styles and scripts options in your angular.json configuration now allow to reference a package directly:

before: "styles": ["../node_modules/bootstrap/dist/css/bootstrap.css"]
after: "styles": ["bootstrap/dist/css/bootstrap.css"]

          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","bootstrap/dist/css/bootstrap.min.css"

            ],
            "scripts": [
                       "jquery/dist/jquery.min.js",
                       "bootstrap/dist/js/bootstrap.min.js"
                       ]
          },

Angular Version 10 and below

Angular v6 Onwards

CLI projects in angular 6 onwards will be using angular.json instead of .angular-cli.json for build and project configuration.

Each CLI workspace has projects, each project has targets, and each target can have configurations.Docs

. {
  "projects": {
    "my-project-name": {
      "projectType": "application",
      "architect": {
        "build": {
          "configurations": {
            "production": {},
            "demo": {},
            "staging": {},
          }
        },
        "serve": {},
        "extract-i18n": {},
        "test": {},
      }
    },
    "my-project-name-e2e": {}
  },
}

OPTION-1
execute npm install bootstrap@4 jquery --save
The JavaScript parts of Bootstrap are dependent on jQuery. So you need the jQuery JavaScript library file too.

In your angular.json add the file paths to the styles and scripts array in under build target
NOTE: Before v6 the Angular CLI project configuration was stored in <PATH_TO_PROJECT>/.angular-cli.json. As of v6 the location of the file changed to angular.json. Since there is no longer a leading dot, the file is no longer hidden by default and is on the same level.
which also means that file paths in angular.json should not contain leading dots and slash

i.e you can provide an absolute path instead of a relative path

In .angular-cli.json file Path was "../node_modules/"
In angular.json it is "node_modules/"

 "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","node_modules/bootstrap/dist/css/bootstrap.min.css"
               
            ],
            "scripts": ["node_modules/jquery/dist/jquery.min.js",
                       "node_modules/bootstrap/dist/js/bootstrap.min.js"]
          },

OPTION 2
Add files from CDN (Content Delivery Network) to your project CDN LINK

Open file src/index.html and insert

the <link> element at the end of the head section to include the Bootstrap CSS file
a <script> element to include jQuery at the bottom of the body section
a <script> element to include Popper.js at the bottom of the body section
a <script> element to include the Bootstrap JavaScript file at the bottom of the body section

  <!doctype html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>Angular</title>
      <base href="/">
      <meta name="viewport" content="width=device-width, initial-scale=1">

    </body>
    </html>

OPTION 3
Execute npm install bootstrap
In src/styles.css add the following line:

@import "~bootstrap/dist/css/bootstrap.css";

OPTION-4
ng-bootstrap It contains a set of native Angular directives based on Bootstrap’s markup and CSS. As a result, it's not dependent on jQuery or Bootstrap’s JavaScript

npm install --save @ng-bootstrap/ng-bootstrap

After Installation import it in your root module and register it in @NgModule imports` array

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})

NOTE
ng-bootstrap requires Bootstrap's 4 css to be added in your project. you need to Install it explicitly via:
npm install bootstrap@4 --save In your angular.json add the file paths to the styles array in under build target

   "styles": [
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css"
   ],

P.S Do Restart Your server

Loop through object with arrow functions

ES6

Object.keys(myObj).forEach(key => {
    console.log(key + ' - ' + myObj[key]) // key - value
})

ES7

Object.entries(myObj).forEach(([key, value]) => {
    console.log(key + ' - ' + value) // key - value
})

ES8

Loop through objects with ES8 with explanation

tldr;

$ awk '{print $NF}' file.txt | paste -sd, | sed 's/,/, /g'

For a file like this

$ cat file.txt
The quick brown fox
jumps over
the lazy dog.

the given command will print

fox, over, dog.

How it works:

• awk '{print $NF}' : prints the last field of every line
• paste -sd, : reads stdin serially (-s, one file at a time) and writes fields comma-delimited (-d,)
• sed 's/,/, /g' : substitutes "," with ", " globally (for all instances)

For canvas in Chrome (Version 52)

All listed answers is about images. But my issue is about canvas in chrome (v.52) with transform rotate. They became jagged and all this methods can't help.

Solution that works for me:

1. Make canvas larger on 1 px for each side => +2 px for width and height;
2. Draw image with offset + 1px (in position 1,1 instead of 0,0) and fixed size (size of image should be 2px less than size of canvas)
3. Apply required rotation

So important code blocks:

// Unfixed version
ctx.drawImage(img, 0, 0, 335, 218);
// Fixed version
ctx.drawImage(img, 1, 1, 335, 218);

/* This style should be applied for fixed version */
canvas {
  margin-left: -1px;
  margin-top:-1px;
}        

<!--Unfixed version-->
<canvas width="335" height="218"></canvas>
<!--Fixed version-->
<canvas width="337" height="220"></canvas>

Sample: https://jsfiddle.net/tLbxgusx/1/

Note: there is a lot of nested divs because it is simplified version from my project.

This issue is reproduced also for Firefox for me. There is no such issue on Safari and FF with retina.

And other founded solution is to place canvas into div of same size and apply following css to this div:

overflow: hidden;
box-shadow: 0 0 1px rgba(255,255,255,0);
// Or
//outline:1px solid transparent;

And rotation should be applied to this wrapping div. So listed solution is worked but with small modification.

And modified example for such solution is: https://jsfiddle.net/tLbxgusx/2/

Note: See style of div with class 'third'.

I would recommend installing everything via homebrew if you have the option. I went in circles for a while, but installing php 5.x via brew and then the neccessary modules worked a treat. I was working with php 5.4 and used this to get going initially:

https://github.com/josegonzalez/homebrew-php

and then installed the additional modules with:

brew install php54-redis
brew install php54-xdebug
brew install php54-mcrypt

...

You can use the $set syntax if you want to set the value of a document to an arbitrary value. This will either update the value if the attribute already exists on the document or create it if it doesn't. If you need to set a single value in a dictionary like you describe, you can use the dot notation to access child values.

If p is the object retrieved:

existing = p['d']['a']

For pymongo versions < 3.0

db.ProductData.update({
  '_id': p['_id']
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False, multi=False)

For pymongo versions >= 3.0

db.ProductData.update_one({
  '_id': p['_id']
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False)

However if you just need to increment the value, this approach could introduce issues when multiple requests could be running concurrently. Instead you should use the $inc syntax:

For pymongo versions < 3.0:

db.ProductData.update({
  '_id': p['_id']
},{
  '$inc': {
    'd.a': 1
  }
}, upsert=False, multi=False)

For pymongo versions >= 3.0:

db.ProductData.update_one({
  '_id': p['_id']
},{
  '$inc': {
    'd.a': 1
  }
}, upsert=False)

This ensures your increments will always happen.

If you don't care about the order...

def split(list):  
    return list[::2], list[1::2]

list[::2] gets every second element in the list starting from the 0th element.
list[1::2] gets every second element in the list starting from the 1st element.

In idlelib.PyShell module, root variable of type Tk is defined to be global

At the end of PyShell.main() function it calls root.mainloop() function which is an infinite loop and it runs till the loop is interrupted by root.quit() function. Hence, root.quit() will only interrupt the execution of mainloop

In order to destroy all widgets pertaining to that idlelib window, root.destroy() needs to be called, which is the last line of idlelib.PyShell.main() function.

var startDate = "06/27/2007";
startDate = new Date(startDate);

console.log(startDate);

Only a slight change in Sat Code, set the layout after show() method of AlertDialog.

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);
builder.setTitle("Title");
alertDialog = builder.create();
alertDialog.show();
alertDialog.getWindow().setLayout(600, 400); //Controlling width and height.

Or you can do it in my way.

alertDialog.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();

lp.copyFrom(alertDialog.getWindow().getAttributes());
lp.width = 150;
lp.height = 500;
lp.x=-170;
lp.y=100;
alertDialog.getWindow().setAttributes(lp);

Unless you have sudo permissions to change it or its in your own usergroup/account you will not be able to get into it.

Check out man chmod in the terminal for more information about changing permissions of a directory.

I'm using get-json very simple to use:

$ npm install get-json --save

Import get-json

var getJSON = require('get-json')

To do a GET request you would do something like:

getJSON('http://api.listenparadise.org', function(error, response){
    console.log(response);
})

To Hide the Action Bar add the below code in Values/Styles

<style name="CustomActivityThemeNoActionBar" parent="@android:style/Theme.Holo.Light">
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

Then in your AndroidManifest.xml file add the below code in the required activity

<activity
        android:name="com.newbelievers.android.NBMenu"
        android:label="@string/title_activity_nbmenu"
        android:theme="@style/CustomActivityThemeNoActionBar">
</activity>

I think the fix here was the keystore type, pkcs12(pfx) always have private key and JKS type can exist without private key. Unless you specify in your code or select a certificate thru browser, the server have no way of knowing it is representing a client on the other end.

I quote from http://www.php.net/manual/en/language.oop5.visibility.php

Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an E_STRICT warning.

select T.object_id, T.name, I.indid, I.rows 
  from Sys.tables T 
  left join Sys.sysindexes I 
    on (I.id = T.object_id and (indid =1 or indid =0 ))
 where T.type='U'

Here indid=1 means a CLUSTERED index and indid=0 is a HEAP

Here is how I would write a validator for MaxValue

public class MaxValueAttribute : ValidationAttribute
    {
        private readonly int _maxValue;

        public MaxValueAttribute(int maxValue)
        {
            _maxValue = maxValue;
        }

        public override bool IsValid(object value)
        {
            return (int) value <= _maxValue;
        }
    }

The MinValue Attribute should be fairly the same

Please find in the below code which enables to perform the date validation for any of the supplied format or based on user locale to validate start/from and end/to dates. There could be some better approaches but have come up with this. Have tested it for the formats like: MM/dd/yyyy, dd/MM/yyyy, yyyy-MM-dd, yyyy.MM.dd, yyyy/MM/dd and dd-MM-yyyy.

Note supplied date format and date string go hand in hand.

    <script type="text/javascript">
function validate(format) {

    if(isAfterCurrentDate(document.getElementById('start').value, format)) {
        alert('Date is after the current date.');
    } else {
        alert('Date is not after the current date.');
    }
    if(isBeforeCurrentDate(document.getElementById('start').value, format)) {
        alert('Date is before current date.');
    } else {
        alert('Date is not before current date.');
    }
    if(isCurrentDate(document.getElementById('start').value, format)) {
        alert('Date is current date.');
    } else {
        alert('Date is not a current date.');
    }
    if (isBefore(document.getElementById('start').value, document.getElementById('end').value, format)) {
        alert('Start/Effective Date cannot be greater than End/Expiration Date');
    } else {
        alert('Valid dates...');
    }
    if (isAfter(document.getElementById('start').value, document.getElementById('end').value, format)) {
        alert('End/Expiration Date cannot be less than Start/Effective Date');
    } else {
        alert('Valid dates...');
    }
    if (isEquals(document.getElementById('start').value, document.getElementById('end').value, format)) {
        alert('Dates are equals...');
    } else {
        alert('Dates are not equals...');
    }
    if (isDate(document.getElementById('start').value, format)) {
        alert('Is valid date...');
    } else {
        alert('Is invalid date...');
    }
}

f.readlines() returns a list that contains each line as an item in the list

if you want eachline to be split(",") you can use list comprehensions

[ list.split(",") for line in file ]

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

from HERE

new StringBuilder().append(str.charAt(0))
                   .append(str.charAt(10))
                   .append(str.charAt(20))
                   .append(str.charAt(30))
                   .toString();

This way you can get the new string with whatever characters you want.

public void onRestart() {
    super.onRestart();
    Intent intent=new Intent();
    intent.setClass(act, act.getClass());
    finish();
    act.startActivity(intent);
}

try to use this ..

 public void updateRecord(ContactModel contact) {
    database = this.getReadableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put(COLUMN_FIRST_NAME, contact.getFirstName());
    contentValues.put(COLUMN_LAST_NAME, contact.getLastName());
    contentValues.put(COLUMN_NUMBER,contact.getNumber());
    contentValues.put(COLUMN_BALANCE,contact.getBalance());
    database.update(TABLE_NAME, contentValues, COLUMN_ID + " = ?", new String[]{contact.getID()});
    database.close();
}

This is how I solved my problem

Let's assume the upstream branch is the one that you forked from and origin is your repo and you want to send an MR/PR to the upstream branch.

You already have let's say about 4 commits and you are getting Updates were rejected because the tip of your current branch is behind.

Here is what I did

First, squash all your 4 commits

git rebase -i HEAD~4

You'll get a list of commits with pick written on them. (opened in an editor)

example

pick fda59df commit 1
pick x536897 commit 2
pick c01a668 commit 3
pick c011a77 commit 4

to

pick fda59df commit 1
squash x536897 commit 2
squash c01a668 commit 3
squash c011a77 commit 4

After that, you can save your combined commit

Next

You'll need to stash your commit

Here's how

git reset --soft HEAD~1
git stash

now rebase with your upstream branch

git fetch upstream beta && git rebase upstream/beta

Now pop your stashed commit

git stash pop

commit these changes and push them

git add -A
git commit -m "[foo] - foobar commit"
git push origin fix/#123 -f

A VERY BAD CAVEAT : Division by Zero

in a 1/x fraction, up to x = 1e-323 it is inf but when x = 1e-324 or little it throws ZeroDivisionError

>>> 1/1e-323
inf

>>> 1/1e-324
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ZeroDivisionError: float division by zero

so be cautious!

Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:

<xsl:template match="class">
  <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  <xsl:variable name="subexists">
    <xsl:choose>
      <xsl:when test="joined-subclass">true</xsl:when>
      <xsl:otherwise>false</xsl:otherwise>
    </xsl:choose>
  </xsl:variable>
  subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

And if you need the variable to have "global" scope then declare it outside of the template:

<xsl:variable name="subexists">
  <xsl:choose>
     <xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
     <xsl:otherwise>false</xsl:otherwise>
  </xsl:choose>
</xsl:variable>

<xsl:template match="class">
   subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

        Object AccountObject = _dbContext.Accounts
                                   .Join(_dbContext.Users, acc => acc.AccountId, usr => usr.AccountId, (acc, usr) => new { acc, usr })
                                   .Where(x => x.usr.EmailAddress == key1)
                                   .Where(x => x.usr.Hash == key2)
                                   .Select(x => new { AccountId = x.acc.AccountId, Name = x.acc.Name })
                                   .SingleOrDefault();

You can do it this way:

Declare interface:

public interface MyInterface{
    public void foo();
}

Let your Activity imlement it:

    public class MyActivity extends Activity implements MyInterface{
        public void foo(){
            //do stuff
        }
        
        public onCreate(){
            //your code
            MyAdapter adapter = new MyAdapter(this); //this will work as your 
                                                     //MyInterface listener
        }
    }

Then pass your activity to ListAdater:

public MyAdapter extends BaseAdater{
    private MyInterface listener;

    public MyAdapter(MyInterface listener){
        this.listener = listener;
    }
}

And somewhere in adapter, when you need to call that Activity method:

listener.foo();

How about:

echo "hello" >> <filename>

Using the >> operator will append data at the end of the file, while using the > will overwrite the contents of the file if already existing.

You could also use printf in the same way:

printf "hello" >> <filename>

Note that it can be dangerous to use the above. For instance if you already have a file and you need to append data to the end of the file and you forget to add the last > all data in the file will be destroyed. You can change this behavior by setting the noclobber variable in your .bashrc:

set -o noclobber

Now when you try to do echo "hello" > file.txt you will get a warning saying cannot overwrite existing file.

To force writing to the file you must now use the special syntax:

echo "hello" >| <filename>

You should also know that by default echo adds a trailing new-line character which can be suppressed by using the -n flag:

echo -n "hello" >> <filename>

References

• echo(1) - Linux man page
• noclobber variable
• I/O Redirection

Well, tempnam() will do it for you.

http://us2.php.net/manual/en/function.tempnam.php

but that creates an entirely new name.

To sanitize an existing string just restrict what your users can enter and make it letters, numbers, period, hyphen and underscore then sanitize with a simple regex. Check what characters need to be escaped or you could get false positives.

$sanitized = preg_replace('/[^a-zA-Z0-9\-\._]/','', $filename);

Alternatively, you can cast the row DataItem to a class and then add condition based on the class properties. Here is a sample that I used to convert the row to a class/model named TimetableModel, then in if statement you have access to all class fields/properties:

protected void GridView_TimeTable_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    var tt = (TimetableModel)(e.Row.DataItem);
                     if (tt.Unpublsihed )
                       e.Row.BackColor = System.Drawing.Color.Red;
                     else
                       e.Row.BackColor = System.Drawing.Color.Green;
                }
            }
        }

You can use RegEdit to export the following two keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

HKEY_CURRENT_USER\Environment

The first set are system/global environment variables; the second set are user-level variables. Edit as needed and then import the .reg files on the new machine.

For HTML5, you can use the 'hidden' attribute.

<option hidden>Hidden option</option>

It is not supported by IE < 11. But if you need only to hide a few elements, maybe it would be better to just set the hidden attribute in combination with disabled in comparison to adding/removing elements or doing not semantically correct constructions.

<select>  _x000D_
  <option>Option1</option>_x000D_
  <option>Option2</option>_x000D_
  <option hidden>Hidden Option</option>_x000D_
</select>

Reference.

Nothing was working for me.

PHP_EOL

. "\r\n";

$NEWLINE_RE = '/(\r\n)|\r|\n/'; // take care of all possible newline-encodings in input file
$var = preg_replace($NEWLINE_RE,'', $var);

Works for me:

$admin_email_Body = $admin_mail_body .'<br>' ."\r\n";
$admin_email_Body .= 'This is line 2 <br>' ."\r\n";
$admin_email_Body .= 'This is line 3 <br>' ."\r\n";

From your question, you are running python2.7 and Cygwin.

Python should be installed for windows, which from your question it seems it is. If "which python" prints out /usr/bin/python , then from the bash prompt you are running the cygwin version.

Set the Python Environmental variables appropriately , for instance in my case:

PY_HOME=C:\opt\Python27
PYTHONPATH=C:\opt\Python27;c:\opt\Python27\Lib

In that case run cygwin setup and uninstall everything python. After that run "which pydoc", if it shows

/usr/bin/pydoc

Replace /usr/bin/pydoc with

#! /bin/bash
 /cygdrive/c/WINDOWS/system32/cmd /c %PYTHONHOME%\Scripts\\pydoc.bat

Then add this to $PY_HOME/Scripts/pydoc.bat

rem wrapper for pydoc on Win32
@python c:\opt\Python27\Lib\pydoc.py %*

Now when you type in the cygwin bash prompt you should see:

$ pydoc
 pydoc - the Python documentation tool

 pydoc.py <name> ...
   Show text documentation on something.  <name> 
   may be the name of a Python keyword, topic,
   function, module, or package, or a dotted
   reference to a class or function within a
   module or module in a package.
...

I see that we have (beside others) basically two options:

a.sort_by { |h| -h[:bar] }

and

a.sort_by { |h| h[:bar] }.reverse

While both ways give you the same result when your sorting key is unique, keep in mind that the reverse way will reverse the order of keys that are equal.

Example:

a = [{foo: 1, bar: 1},{foo: 2,bar: 1}]
a.sort_by {|h| -h[:bar]}
 => [{:foo=>1, :bar=>1}, {:foo=>2, :bar=>1}]
a.sort_by {|h| h[:bar]}.reverse
 => [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]

While you often don't need to care about this, sometimes you do. To avoid such behavior you could introduce a second sorting key (that for sure needs to be unique at least for all items that have the same sorting key):

a.sort_by {|h| [-h[:bar],-h[:foo]]}
 => [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]
a.sort_by {|h| [h[:bar],h[:foo]]}.reverse
 => [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]

As stated by Luke you need to use a server side language, like php. This is a really simple php example:

<?php
if ($_GET['run']) {
  # This code will run if ?run=true is set.
  exec("/path/to/name.sh");
}
?>

<!-- This link will add ?run=true to your URL, myfilename.php?run=true -->
<a href="?run=true">Click Me!</a>

Save this as myfilename.php and place it on a machine with a web server with php installed. The same thing can be accomplished with asp, java, ruby, python, ...

There is a free python tool called YouTube transcript API

You can use it in scripts or as a command line tool:

pip install youtube_transcript_api

Yes, Eclipse can be a pain, as almost any IDE can. Please remain factual, however.

Switching to a new workspace should help you. Eclipse has almost no settings that are stored outside your workspace.

Inner join.

A join is combining the rows from two tables. An inner join attempts to match up the two tables based on the criteria you specify in the query, and only returns the rows that match. If a row from the first table in the join matches two rows in the second table, then two rows will be returned in the results. If there’s a row in the first table that doesn’t match a row in the second, it’s not returned; likewise, if there’s a row in the second table that doesn’t match a row in the first, it’s not returned.

Outer Join.

A left join attempts to find match up the rows from the first table to rows in the second table. If it can’t find a match, it will return the columns from the first table and leave the columns from the second table blank (null).

You can use the monitoring program glances with its GPU monitoring plug-in:

• open source
• to install: sudo apt-get install -y python-pip; sudo pip install glances[gpu]
• to launch: sudo glances

It also monitors the CPU, disk IO, disk space, network, and a few other things:

Put non-breaking spaces in your text instead of normal spaces. On Ubuntu I do this with (Compose Key)-space-space.

I was having this same issue. I found out if you go to the Task in Task Scheduler that is running the powershell.exe script, you can click "Run whether user is logged on or not" and that will never show the powershell window when the task runs.

There are lots of free tools that can do this.

I use PDFTK (a open source cross-platform command-line tool) for things like that.

  function randomPassword(length) {
        var chars = "abcdefghijklmnopqrstuvwxyz#$%ABCDEFGHIJKLMNOP1234567890";
        var pass = "";
        for (var x = 0; x < length; x++) {
            var i = Math.floor(Math.random() * chars.length);
            pass += chars.charAt(i);
        }
        var pattern = false;
        var passwordpattern = new RegExp("[^a-zA-Z0-9+]+[0-9+]+[A-Z+]+[a-z+]");
        pattern = passwordpattern.test(pass);
        if (pattern == true)
            { alert(pass); }
        else
         { randomPassword(length); }
    }

try this to create the random password with atleast one special character

Can use Extension Code Runner to run code with play icon on top Right ans by shortcut key :Ctrl+Alt+N and to abort Ctrl+Alt+M. But by default it only shows output of program but for receiving input you need to follow some steps:

Ctrl+, and then settings menu opens and Extensions>Run Code Configuration scroll down its attributes and find Edit in settings.json click on it and add following code insite it :

{ "code-runner.runInTerminal": true }

Basically, what this error is saying is that if you are going to use the GROUP BY clause, then your result is going to be a relation/table with a row for each group, so in your SELECT statement you can only "select" the column that you are grouping by and use aggregate functions on that column because the other columns will not appear in the resulting table.

This worked for me, as documented on this page:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer trans = tf.newTransformer();
StringWriter sw = new StringWriter();
trans.transform(new DOMSource(document), new StreamResult(sw));
return sw.toString();

Sometimes I need to get unique occurrences from an array of objects. Lodash seems like a nice helper but I don't think filtering an array justifies adding a dependency to a project.

Let's assume the comparison of two objects poses on comparing a property, an id for example.

const a = [{id: 3}, {id: 4}, {id: 3}, {id: 5}, {id: 5}, {id: 5}];

Since we all love one line snippets, here is how it can be done:

a.reduce((acc, curr) => acc.find(e => e.id === curr.id) ? acc : [...acc, curr], [])

Unfortunately, you can't import a class without it being in a package. This is one of the reasons it's highly discouraged. What I would try is a sort of proxy -- put your code into a package which anything can use, but if you really need something in the default package, make that a very simple class which forwards calls to the class with the real code. Or, even simpler, just have it extend.

To give an example:

import my.packaged.DefaultClass;

public class MyDefaultClass extends DefaultClass {}

package my.packaged.DefaultClass;

public class DefaultClass {

   // Code here

}

When you say "copy the contents of a variable", does that variable contain a file name, or does it contain a name of a file?

I'm assuming by your question that $var contains the contents you want to copy into the file:

$ echo "$var" > "$destdir"

This will echo the value of $var into a file called $destdir. Note the quotes. Very important to have "$var" enclosed in quotes. Also for "$destdir" if there's a space in the name. To append it:

$ echo "$var" >> "$destdir"

$("a.more").click(function() {
                 $.fancybox({
                  'padding'             : 0,
                  'autoScale'   : false,
                  'transitionIn'        : 'none',
                  'transitionOut'       : 'none',
                  'title'               : this.title,
                  'width'               : 680,
                  'height'              : 495,
                  'href'                : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
                  'type'                : 'swf',    // <--add a comma here
                  'swf'                 : {'allowfullscreen':'true'} // <-- flashvars here
                  });
                 return false;

            }); 

You can of course use a loop, or you can insert them in a single statement, e.g.

Insert into db
(names,email,password) 
Values
('abc','def','mypassword')
,('ghi','jkl','mypassword2')
,('mno','pqr','mypassword3')

It really depends where you're getting your data from.

If you use a loop, wrapping it in a transaction will make it a bit faster.

UPDATE

What if i want to insert unique names?

If you want to insert unique names, then you need to generate data with unique names. One way to do this is to use Visual Studio to generate test data.

Since i'm working with Bootstrap Javascript Modules instead of loading the entire Bootstrap Javascript, my tabs were not working because i forgot to load load/include/ the node_modules/bootstrap/js/tab.js file.

After including it, it worked...

Good Luck

jQuery API documentation - datepicker

The minimum selectable date. When set to null, there is no minimum.

Multiple types supported:

Date: A date object containing the minimum date.
Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.
String: A string in the format defined by the dateFormat option, or a relative date.
Relative dates must contain value and period pairs; valid periods are y for years, m for months, w for weeks, and d for days. For example, +1m +7d represents one month and seven days from today.

In order not to display previous dates other than today

$('#datepicker').datepicker({minDate: 0});

If you are not sharing develop branch with anybody, then I would just rebase it every time master updated, that way you will not have merge commits all over your history once you will merge develop back into master. Workflow in this case would be as follows:

> git clone git://<remote_repo_path>/ <local_repo>
> cd <local_repo>
> git checkout -b develop
....do a lot of work on develop
....do all the commits
> git pull origin master
> git rebase master develop

Above steps will ensure that your develop branch will be always on top of the latest changes from the master branch. Once you are done with develop branch and it's rebased to the latest changes on master you can just merge it back:

> git checkout -b master
> git merge develop
> git branch -d develop

You can read an article i have written for joins in LINQ here

var query = 
from  u in Repo.T_Benutzer
join bg in Repo.T_Benutzer_Benutzergruppen
    on u.BE_ID equals bg.BEBG_BE
into temp
from j in temp.DefaultIfEmpty()
select new
{
    BE_User = u.BE_User,
    BEBG_BG = (int?)j.BEBG_BG// == null ? -1 : j.BEBG_BG
            //, bg.Name 
}

The following is the equivalent using extension methods:

var query = 
Repo.T_Benutzer
.GroupJoin
(
    Repo.T_Benutzer_Benutzergruppen,
    x=>x.BE_ID,
    x=>x.BEBG_BE,
    (o,i)=>new {o,i}
)
.SelectMany
(
    x => x.i.DefaultIfEmpty(),
    (o,i) => new
    {
        BE_User = o.o.BE_User,
        BEBG_BG = (int?)i.BEBG_BG
    }
);

I use this when converting log files or monitoring them:

tail -f <log file> | gawk \
'{ printf strftime("%c", $1); for (i=2; i<NF; i++) printf $i " "; print $NF }'

InstanceID.getInstance(getApplicationContext()).getToken(authorizedEntity,scope)

authorizedEntity is the project number of the server

Try to make your css more specific so that the new (green) style is more specific than the previous one, so that it worked for me!

For example, you might use in css:

button:active {/*your style here*/}

Instead of (probably not working):

.active {/*style*/} (.active is not a pseudo-class)

Hope it helps!

Note that services and tools for sending emails may be able to inline your CSS for you, allowing CSS in <style> tags to work in Gmail.

For instance, if you're sending emails with MailChimp, your CSS from <style> tags will get inlined automatically by default. With Mandrill, you can enable this functionality (although it's disabled by default for performance reasons) by checking the "Inline CSS Styles in HTML Emails" box in the "Sending Defaults" section of the Settings tab:

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

I came across the same nagging error, which I realized has something to do with a cool feature PyCharm automatically detects...just add the @staticmethod decorator, and it will automatically remove that error where the method is used

@Eevee: As the browser becomes the home for richer and richer functionality and starts to replace desktop apps, it's just not going to be an option to forgo the use of keyboard shortcuts. Gmail's rich and intuitive set of keyboard commands was instrumental in my willingness to abandon Outlook. The keyboard shortcuts in Todoist, Google Reader, and Google Calendar all make my life much, much easier on a daily basis.

Developers should definitely be careful not to override keystrokes that already have a meaning in the browser. For example, the WMD textbox I'm typing into inexplicably interprets Ctrl+Del as "Blockquote" rather than "delete word forward". I'm curious if there's a standard list somewhere of "browser-safe" shortcuts that site developers can use and that browsers will commit to staying away from in future versions.

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

The following should help

• realpath — Returns canonicalized absolute pathname
• is_writable — Tells whether the filename is writable
• unlink — Deletes a file

Run your filepath through realpath, then check if the returned path is writable and if so, unlink it.

Have you tried the uncurl package (https://github.com/spulec/uncurl)? You can install it via pip, pip install uncurl. Your curl request returns:

>>> uncurl "curl --header \"Authorization:access_token myToken\" https://website.com/id"

requests.get("https://website.com/id",
    headers={
        "Authorization": "access_token myToken"
    },
    cookies={},
)

    public static bool isInteger(decimal n)
    {
        return n - (Int64)n == 0;
    }

Overloading is a part of static polymorphism and is used to implement different method with same name but different signatures. Overriding is used to complete the incomplete method. In my opinion there is no comparison between these two concepts, the only thing is similar is that both come with the same vocabulary that is over.

Try this for the file format:

[default]
aws_access_key_id=<your access key>
aws_secret_access_key=<your secret access key>

I saved this file as ~/.aws/credentials with ProfileCredentialsProvider().

I had this problem with device. My ads worked without problems with UnitID Test Emulator, but when testing on my device it doesn't work with message "failed to load ad: 3"

My solution was to test the app in the internal test environment of Google Play Console creating User Verifiers

Then I downloaded the app on the same device from Google Play internal testing and the ads worked for me, and it worked in production too

Simple, [yourobject class] it will return the class name of yourobject.

The code given in the links http://clc-wiki.net/wiki/memcpy for memcpy seems to confuse me a bit, as it does not give the same output when I implemented it using the below example.

#include <memory.h>
#include <string.h>
#include <stdio.h>

char str1[11] = "abcdefghij";

void *memcpyCustom(void *dest, const void *src, size_t n)
{
    char *dp = (char *)dest;
    const char *sp = (char *)src;
    while (n--)
        *dp++ = *sp++;
    return dest;
}

void *memmoveCustom(void *dest, const void *src, size_t n)
{
    unsigned char *pd = (unsigned char *)dest;
    const unsigned char *ps = (unsigned char *)src;
    if ( ps < pd )
        for (pd += n, ps += n; n--;)
            *--pd = *--ps;
    else
        while(n--)
            *pd++ = *ps++;
    return dest;
}

int main( void )
{
    printf( "The string: %s\n", str1 );
    memcpy( str1 + 1, str1, 9 );
    printf( "Actual memcpy output: %s\n", str1 );

    strcpy_s( str1, sizeof(str1), "abcdefghij" );   // reset string

    memcpyCustom( str1 + 1, str1, 9 );
    printf( "Implemented memcpy output: %s\n", str1 );

    strcpy_s( str1, sizeof(str1), "abcdefghij" );   // reset string

    memmoveCustom( str1 + 1, str1, 9 );
    printf( "Implemented memmove output: %s\n", str1 );
    getchar();
}

Output :

The string: abcdefghij
Actual memcpy output: aabcdefghi
Implemented memcpy output: aaaaaaaaaa
Implemented memmove output: aabcdefghi

But you can now understand why memmove will take care of overlapping issue.

This is default by iOS7 design. try to do the below:

[tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];

You can set the 'Separator Inset' from the storyboard:

Consider the array a:

var a ={'name1':1, 'name2':2}

If you want to check if 'name1' exists in a, simply test it with in:

if('name1' in a){
console.log('name1 exists in a')
}else
console.log('name1 is not in a')

Though we have many answers here with plenty of useful suggestions, each of them still misses some steps.
So here is a complete solution wrapped into small function:

function roundToTwoDigitsAfterComma(floatNumber) {
    return parseFloat((Math.round(floatNumber * 100) / 100).toFixed(2));
}

Just in case you are interested how this works:

1. Multiple with 100 and then do round to keep precision of 2 digits after comma
2. Divide back into 100 and use toFixed(2) to keep 2 digits after comma and throw other unuseful part
3. Convert it back to float by using parseFloat() function as toFixed(2) returns string instead

Note: If you keep last 2 digits after comma because of working with monetary values, and doing financial calculations keep in mind that it's not a good idea and you'd better use integer values instead.

bs := string(body) should be enough to give you a string.

From there, you can use it as a regular string.

A bit as in this thread:

var client http.Client
resp, err := client.Get(url)
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()

if resp.StatusCode == http.StatusOK {
    bodyBytes, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        log.Fatal(err)
    }
    bodyString := string(bodyBytes)
    log.Info(bodyString)
}

See also GoByExample.

As commented below (and in zzn's answer), this is a conversion (see spec).
See "How expensive is []byte(string)?" (reverse problem, but the same conclusion apply) where zzzz mentioned:

Some conversions are the same as a cast, like uint(myIntvar), which just reinterprets the bits in place.

Sonia adds:

Making a string out of a byte slice, definitely involves allocating the string on the heap. The immutability property forces this.
Sometimes you can optimize by doing as much work as possible with []byte and then creating a string at the end. The bytes.Buffer type is often useful.

or programatically

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();

Here is how you would do it with Apache HttpClient (this solution is for those who don't mind using a 3rd party library):

    HttpEntity entity = MultipartEntityBuilder.create()
                       .addPart("file", new FileBody(file))
                       .build();

    HttpPost request = new HttpPost(url);
    request.setEntity(entity);

    HttpClient client = HttpClientBuilder.create().build();
    HttpResponse response = client.execute(request);

I think the params config parameter won't work here since it adds the string to the url instead of the body but to add to what Infeligo suggested here is an example of the global override of a default transform (using jQuery param as an example to convert the data to param string).

Set up global transformRequest function:

var app = angular.module('myApp');

app.config(function ($httpProvider) {
    $httpProvider.defaults.transformRequest = function(data){
        if (data === undefined) {
            return data;
        }
        return $.param(data);
    }
});

That way all calls to $http.post will automatically transform the body to the same param format used by the jQuery $.post call.

Note you may also want to set the Content-Type header per call or globally like this:

$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';

Sample non-global transformRequest per call:

    var transform = function(data){
        return $.param(data);
    }

    $http.post("/foo/bar", requestData, {
        headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'},
        transformRequest: transform
    }).success(function(responseData) {
        //do stuff with response
    });

I User this Code in my project, Useful for me.

    private void Form1_Resize(object sender, EventArgs e)
    {
        int w = MainPanel.Width; // you can use form.width when you don't use panels

        w = (w - 120)/4; // 120 because set 15px for each side of panels
                         // and put panels in FlowLayoutPanel
                         // 4 because i have 4 panel boxes
        panel1.Width = w;
        panel2.Width = w;
        panel3.Width = w;
        panel4.Width = w;
    }

I have implemented the Samsung File Selector Dialog, it provides the ability to open, save file, file extension filter, and create new directory in the same dialog I think it worth trying Here is the Link you have to log in to Samsung developer site to view the solution

All you need to do is pass the JspWriter object into your method as a parameter i.e.

void someOutput(JspWriter stream)

Then call it via:

<% someOutput(out) %>

The writer object is a local variable inside _jspService so you need to pass it into your utility method. The same would apply for all the other built in references (e.g. request, response, session).

A great way to see whats going on is to use Tomcat as your server and drill down into the 'work' directory for the '.java' file generated from your 'jsp' page. Alternatively in weblogic you can use the 'weblogic.jspc' page compiler to view the Java that will be generated when the page is requested.

I am stuck with same issue and find the easiest way to do this...

//Html
<button type="button" onclick="history.back()">Back</button>

OR

//Html
<button type="button" ng-click="goBack()">Back</button>

//JS
$scope.goBack = function() {
  window.history.back();
};

(If you want it to be more testable, inject the $window service into your controller and use $window.history.back()).

Just wrap the button label in an extra span and add class="align-middle" to both (the icon and the label). This will center your icon with text vertical.

<button id="edit-listing-form-house_Continue" 
    class="btn btn-large btn-primary"
    style=""
    value=""
    name="Continue"
    type="submit">
<span class="align-middle">Continue</span>
<i class="icon-ok align-middle" style="font-size:40px;"></i>

You can also find the name of the current on screen activity using

adb shell dumpsys window windows | grep 'mCurrentFocus'

for x in y[:-1]

If y is a generator, then the above will not work.

Your query contains columns which could be present with the same name in more than one table you are referencing, hence the not unique error. It's best if you make the references explicit and/or use table aliases when joining.

Try

    SELECT pa.ProjectID, p.Project_Title, a.Account_ID, a.Username, a.Access_Type, c.First_Name, c.Last_Name
      FROM Project_Assigned pa
INNER JOIN Account a
        ON pa.AccountID = a.Account_ID
INNER JOIN Project p
        ON pa.ProjectID = p.Project_ID
INNER JOIN Clients c
        ON a.Account_ID = c.Account_ID
     WHERE a.Access_Type = 'Client';

If your browser supports CSS3, try using the CSS element Calc()

height: calc(100% - 65px);

you might also want to adding browser compatibility options:

height: -o-calc(100% - 65px); /* opera */
height: -webkit-calc(100% - 65px); /* google, safari */
height: -moz-calc(100% - 65px); /* firefox */

also make sure you have spaces between values, see: https://stackoverflow.com/a/16291105/427622

A HashSet has an internal structure (hash), where items can be searched and identified quickly. The downside is that iterating through a HashSet (or getting an item by index) is rather slow.

So why would someone want be able to know if an entry already exists in a set?

One situation where a HashSet is useful is in getting distinct values from a list where duplicates may exist. Once an item is added to the HashSet it is quick to determine if the item exists (Contains operator).

Other advantages of the HashSet are the Set operations: IntersectWith, IsSubsetOf, IsSupersetOf, Overlaps, SymmetricExceptWith, UnionWith.

If you are familiar with the object constraint language then you will identify these set operations. You will also see that it is one step closer to an implementation of executable UML.

Ammending as "optional Answer". If you don't need to programmatically solve the problem, here goes the "visual way" in VS2012.

In Visual Studio, you can set custom format directly from the properties Panel:

First Set the "Format" property to: "Custom"; Secondly, set your custom format to: "dd-MM-yyyy";

I have solved this problem, in Java Code, adding:

 MimeHeaders headers = message.getMimeHeaders();

The main image manager in PIL is PIL's Image module.

from PIL import Image
import math

foo = Image.open("path\\to\\image.jpg")
x, y = foo.size
x2, y2 = math.floor(x-50), math.floor(y-20)
foo = foo.resize((x2,y2),Image.ANTIALIAS)
foo.save("path\\to\\save\\image_scaled.jpg",quality=95)

You can add optimize=True to the arguments of you want to decrease the size even more, but optimize only works for JPEG's and PNG's. For other image extensions, you could decrease the quality of the new saved image. You could change the size of the new image by just deleting a bit of code and defining the image size and you can only figure out how to do this if you look at the code carefully. I defined this size:

x, y = foo.size
x2, y2 = math.floor(x-50), math.floor(y-20)

just to show you what is (almost) normally done with horizontal images. For vertical images you might do:

x, y = foo.size
x2, y2 = math.floor(x-20), math.floor(y-50)

. Remember, you can still delete that bit of code and define a new size.

You're doing something wrong (probably too small read buffer). On a machine of undecent age (Athlon 2x1800MP from 2002) that has DMA on disk probably out of whack (6.6M/s is damn slow when doing sequential reads):

Create a 1G file with "random" data:

# dd if=/dev/sdb of=temp.dat bs=1M count=1024    
1073741824 bytes (1.1 GB) copied, 161.698 s, 6.6 MB/s

# time sha1sum -b temp.dat
abb88a0081f5db999d0701de2117d2cb21d192a2 *temp.dat

1m5.299s

# time md5sum -b temp.dat
9995e1c1a704f9c1eb6ca11e7ecb7276 *temp.dat

1m58.832s

This is also weird, md5 is consistently slower than sha1 for me (reran several times).

In addition to the other answers, you can use this less-known method to grab elements of a certain parent like so,

$('child', 'parent');

In your case, that would be

if ($(event.target, 'div#hello')[0]) console.log(`${event.target.tagName} is an offspring of div#hello`);

Note the use of commas between the child and parent and their separate quotation marks. If they were surrounded by the same quotes

$('child, parent');

you'd have an object containing both objects, regardless of whether they exist in their document trees.

In javascript the "+" operator is used to add numbers or to concatenate strings. if one of the operands is a string "+" concatenates, and if it is only numbers it adds them.

example:

1+2+3 == 6
"1"+2+3 == "123"

you should use the break statement

usually it's use this way

$i = 0;
foreach($data as $key => $row){
    if(++$i > 2) break;
}

on the same fashion the continue statement exists if you need to skip some items.

Do this:

<div id="sampleDiv">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>

#sampleDiv{
   overflow-wrap: break-word;
}

I hope this will help to you.

You need to loop over each of the elements in the slice and test. Equality for slices is not defined. However, there is a bytes.Equal function if you are comparing values of type []byte.

func testEq(a, b []Type) bool {

    // If one is nil, the other must also be nil.
    if (a == nil) != (b == nil) { 
        return false; 
    }

    if len(a) != len(b) {
        return false
    }

    for i := range a {
        if a[i] != b[i] {
            return false
        }
    }

    return true
}

This still loops through the cartesian product of the two lists, but it does it one line:

>>> lines1 = ['soup', 'butter', 'venison']
>>> lines2 = ['prune', 'rye', 'turkey']
>>> search_strings = ['a', 'b', 'c']
>>> any(s in l for l in lines1 for s in search_strings)
True
>>> any(s in l for l in lines2 for s in search_strings)
False

This also have the advantage that any short-circuits, and so the looping stops as soon as a match is found. Also, this only finds the first occurrence of a string from search_strings in linesX. If you want to find multiple occurrences you could do something like this:

>>> lines3 = ['corn', 'butter', 'apples']
>>> [(s, l) for l in lines3 for s in search_strings if s in l]
[('c', 'corn'), ('b', 'butter'), ('a', 'apples')]

If you feel like coding something more complex, it seems the Aho-Corasick algorithm can test for the presence of multiple substrings in a given input string. (Thanks to Niklas B. for pointing that out.) I still think it would result in quadratic performance for your use-case since you'll still have to call it multiple times to search multiple lines. However, it would beat the above (cubic, on average) algorithm.

The use of expand as suggested in other answers seems the most logical approach for this task alone.

That said, it can also be done with Bash and Awk in case you may want to do some other modifications along with it.

If using Bash 4.0 or greater, the shopt builtin globstar can be used to search recursively with **.

With GNU Awk version 4.1 or greater, sed like "inplace" file modifications can be made:

shopt -s globstar
gawk -i inplace '{gsub("\t","    ")}1' **/*.ext

In case you want to set the number of spaces per tab:

gawk -i inplace -v n=4 'BEGIN{for(i=1;i<=n;i++) c=c" "}{gsub("\t",c)}1' **/*.ext

This is not like Collections.sort() where the parameter reference gets sorted. In this case you just get a sorted stream that you need to collect and assign to another variable eventually:

List result = list.stream().sorted((o1, o2)->o1.getItem().getValue().
                                   compareTo(o2.getItem().getValue())).
                                   collect(Collectors.toList());

You've just missed to assign the result

herein lies the answer... IIS Settings

IIS-->Default SMTP Virtual Server-->Properties-->Access-->Relay restrictions just add or exclude the IPs you care about, should resolve the issue.

1. PSYoungGen refers to the garbage collector in use for the minor collection. PS stands for Parallel Scavenge.
2. The first set of numbers are the before/after sizes of the young generation and the second set are for the entire heap. (Diagnosing a Garbage Collection problem details the format)
3. The name indicates the generation and collector in question, the second set are for the entire heap.

An example of an associated full GC also shows the collectors used for the old and permanent generations:

3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)] 
            [ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K) 
            [PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]

Finally, breaking down one line of your example log output:

8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]

• 107Mb used before GC, 14Mb used after GC, max young generation size 137Mb
• 675Mb heap used before GC, 581Mb heap used after GC, 1Gb max heap size
• minor GC occurred 8109.128 seconds since the start of the JVM and took 0.04 seconds

The new filtering feature in Servlet 2.4 basically alleviates the restriction that filters can only operate in the request flow before and after the actual request processing by the application server. Instead, Servlet 2.4 filters can now interact with the request dispatcher at every dispatch point. This means that when a Web resource forwards a request to another resource (for instance, a servlet forwarding the request to a JSP page in the same application), a filter can be operating before the request is handled by the targeted resource. It also means that should a Web resource include the output or function from other Web resources (for instance, a JSP page including the output from multiple other JSP pages), Servlet 2.4 filters can work before and after each of the included resources. .

To turn on that feature you need:

web.xml

<filter>   
    <filter-name>springSecurityFilterChain</filter-name>   
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> 
</filter>  
<filter-mapping>   
    <filter-name>springSecurityFilterChain</filter-name>   
    <url-pattern>/<strike>*</strike></url-pattern>
    <dispatcher>REQUEST</dispatcher>
