Use a Temp Table or a Table variable, e.g.

select 'A' as [value]
into #tmp
union
select 'B'
union 
select 'C'

and then

SELECT   
blah 
FROM    foo 
WHERE   myField IN (select [value] from #tmp) 

or

SELECT   
f.blah 
FROM foo f INNER JOIN #tmp t ON f.myField = t.[value]

for OS's that support select:

import select

# your code

select.select([], [], [])

An input field can have whitespaces, we want to prevent that.
Use String.prototype.trim():

function isEmpty(str) {
    return !str.trim().length;
}

Example:

const isEmpty = str => !str.trim().length;_x000D_
_x000D_
document.getElementById("name").addEventListener("input", function() {_x000D_
  if( isEmpty(this.value) ) {_x000D_
    console.log( "NAME is invalid (Empty)" )_x000D_
  } else {_x000D_
    console.log( `NAME value is: ${this.value}` );_x000D_
  }_x000D_
});

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

First, create your splash screen as a borderless, immovable form with your image on it, set to initially display at the center of the screen, colored the way you want. All of this can be set from within the designer; specifically, you want to:

• Set the form's ControlBox, MaximizeBox, MinimizeBox and ShowIcon properties to "False"
• Set the StartPosition property to "CenterScreen"
• Set the FormBorderStyle property to "None"
• Set the form's MinimumSize and MaximumSize to be the same as its initial Size.

Then, you need to decide where to show it and where to dismiss it. These two tasks need to occur on opposite sides of the main startup logic of your program. This could be in your application's main() routine, or possibly in your main application form's Load handler; wherever you're creating large expensive objects, reading settings from the hard drive, and generally taking a long time to do stuff behind the scenes before the main application screen displays.

Then, all you have to do is create an instance of your form, Show() it, and keep a reference to it while you do your startup initialization. Once your main form has loaded, Close() it.

If your splash screen will have an animated image on it, the window will need to be "double-buffered" as well, and you will need to be absolutely sure that all initialization logic happens outside the GUI thread (meaning you cannot have your main loading logic in the mainform's Load handler; you'll have to create a BackgroundWorker or some other threaded routine.

Here's a solution that uses more modern syntax and is less verbose than the ones already provided:

const canvas = document.querySelector("canvas");
const ctx = canvas.getContext("2d");
const video = document.querySelector("video");

video.addEventListener('play', () => {
  function step() {
    ctx.drawImage(video, 0, 0, canvas.width, canvas.height)
    requestAnimationFrame(step)
  }
  requestAnimationFrame(step);
})

You can generally simplify the specification of the parameter BlahActivity::class.java by defining an inline reified generic function.

inline fun <reified T: Activity> Context.createIntent() =
    Intent(this, T::class.java)

Because that lets you do

startActivity(createIntent<Page2>()) 

Or even simpler

inline fun <reified T: Activity> Activity.startActivity() {
    startActivity(createIntent<T>()) 
} 

So it's now

startActivity<Page2>() 

The correct way to create a user in Django is to use the create_user function. This will handle the hashing of the password, etc..

from django.contrib.auth.models import User
user = User.objects.create_user(username='john',
                                 email='[email protected]',
                                 password='glass onion')

None of the Invoke stuff in the previous answers is necessary.

You need to look at WindowsFormsSynchronizationContext:

// In the main thread
WindowsFormsSynchronizationContext mUiContext = new WindowsFormsSynchronizationContext();

...

// In some non-UI Thread

// Causes an update in the GUI thread.
mUiContext.Post(UpdateGUI, userData);

...

void UpdateGUI(object userData)
{
    // Update your GUI controls here
}

For iOS 9 beta 3,4 users. Since the option to view profiles is not viewable do the following from Xcode.

1. Open Xcode 7.
2. Go to window, devices.
3. Select your device.
4. Delete all of the profiles loaded on the device.
5. Delete the old app on your device.
6. Clean and rebuild the app to your device.

On iOS 9.1+ n iOS 9.2+ go to Settings -> General -> Device Management -> press the Profile -> Press Trust.

You can set new indices by using set_index:

df2.set_index(np.arange(len(df2.index)))

Output:

   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0
7  2  1
8  2  2

You can use setdefault.

for line in list:  
    d.setdefault(year, []).append(value)

This works because setdefault returns the list as well as setting it on the dictionary, and because a list is mutable, appending to the version returned by setdefault is the same as appending it to the version inside the dictionary itself. If that makes any sense.

Note to the above solution (from A Paul): The solution doesn't work, cause it doesn't reconstructs back a HashMap< String, Object > - instead it creates a HashMap< String, LinkedHashMap >.

Reason why is because during demarshalling, each Object (JSON marshalled as a LinkedHashMap) is used as-is, it takes 1-on-1 the LinkedHashMap (instead of converting the LinkedHashMap back to its proper Object).

If you had a HashMap< String, MyOwnObject > then proper demarshalling was possible - see following example:

ObjectMapper mapper = new ObjectMapper();
TypeFactory typeFactory = mapper.getTypeFactory();
MapType mapType = typeFactory.constructMapType(HashMap.class, String.class, MyOwnObject.class);
HashMap<String, MyOwnObject> map = mapper.readValue(new StringReader(hashTable.toString()), mapType);

Is it also possible to access the management port in a similar way, e.g.:

  @SpringBootTest(classes = {Application.class}, webEnvironment = WebEnvironment.RANDOM_PORT)
  public class MyTest {

    @LocalServerPort
    int randomServerPort;

    @LocalManagementPort
    int randomManagementPort;

Usually we have the need to control the width of the dropdown menu; specially that's essential when the dropdown menu holds a form, e.g. login form --- then the dropdown menu and its items should be wide enough for ease of inputing username/email and password.

Besides, when the screen is smaller than 768px or when the window (containing the dropdown menu) is zoomed down to smaller than 768px, Bootstrap 3 responsively scales the dropdown menu to the whole width of the screen/window. We need to keep this reponsive action.

Hence, the following css class could do that:

@media (min-width: 768px) {
    .dropdown-menu {
        width: 300px !important;  /* change the number to whatever that you need */
    }
}

(I had used it in my web app.)

+= in JavaScript (as well as in many other languages) adds the right hand side to the variable on the left hand side, storing the result in that variable. Your example of 1 +=2 therefore does not make sense. Here is an example:

var x = 5;
x += 4; // x now equals 9, same as writing x = x + 4;
x -= 3; // x now equals 6, same as writing x = x - 3;
x *= 2; // x now equals 12, same as writing x = x * 2;
x /= 3; // x now equals 4, same as writing x = x / 3;

In your specific example the loop is summing the numbers in the array data.

Had the exact same problem that is described herein. No matter what I did, following the above examples, to change the location of my WSDL file (in our case from a web server), it was still referencing the original location embedded within the source tree of the server process.

After MANY hours trying to debug this, I noticed that the Exception was always being thrown from the exact same line (in my case 41). Finally this morning, I decided to just send my source client code to our trade partner so they can at least understand how the code looks, but perhaps build their own. To my shock and horror I found a bunch of class files mixed in with my .java files within my client source tree. How bizarre!! I suspect these were a byproduct of the JAX-WS client builder tool.

Once I zapped those silly .class files and performed a complete clean and rebuild of the client code, everything works perfectly!! Redonculous!!

YMMV, Andrew

Just found a convenient workaround:

Package Explorer > Context Menu (for specific project) > StartExplorer > Start Shell Here

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

A solution using lodash -

const titleCase = string =>
  padEnd(

      .map(capitalize)
      .join(' '),
    string.length,
  );

You can use CSS3 transition

Your code is, I'm sorry to say, very C-like.

A Java String is not a char[]. You say you want to remove duplicates from a String, but you take a char[] instead.

Is this char[] \0-terminated? Doesn't look like it because you take the whole .length of the array. But then your algorithm tries to \0-terminate a portion of the array. What happens if the arrays contains no duplicates?

Well, as it is written, your code actually throws an ArrayIndexOutOfBoundsException on the last line! There is no room for the \0 because all slots are used up!

You can add a check not to add \0 in this exceptional case, but then how are you planning to use this code anyway? Are you planning to have a strlen-like function to find the first \0 in the array? And what happens if there isn't any? (due to all-unique exceptional case above?).

What happens if the original String/char[] contains a \0? (which is perfectly legal in Java, by the way, see JLS 10.9 An Array of Characters is Not a String)

The result will be a mess, and all because you want to do everything C-like, and in place without any additional buffer. Are you sure you really need to do this? Why not work with String, indexOf, lastIndexOf, replace, and all the higher-level API of String? Is it provably too slow, or do you only suspect that it is?

"Premature optimization is the root of all evils". I'm sorry but if you can't even understand what the original code does, then figuring out how it will fit in the bigger (and messier) system will be a nightmare.

My minimal suggestion is to do the following:

• Make the function takes and returns a String, i.e. public static String removeDuplicates(String in)
• Internally, works with char[] str = in.toCharArray();
• Replace the last line by return new String(str, 0, tail);

This does use additional buffers, but at least the interface to the rest of the system is much cleaner.

Alternatively, you can use StringBuilder as such:

static String removeDuplicates(String s) {
    StringBuilder noDupes = new StringBuilder();
    for (int i = 0; i < s.length(); i++) {
        String si = s.substring(i, i + 1);
        if (noDupes.indexOf(si) == -1) {
            noDupes.append(si);
        }
    }
    return noDupes.toString();
}

Note that this is essentially the same algorithm as what you had, but much cleaner and without as many little corner cases, etc.

The UTF-8 Byte-order marker will clue Excel 2007+ in to the fact that you're using UTF-8. (See this SO post).

In case anybody is having the same issues I was, .NET's UTF8 encoding class does not output a byte-order marker in a GetBytes() call. You need to use streams (or use a workaround) to get the BOM to output.

Translation of the 3 arrows : "Share" - "Embed" - "Show suggested videos when the video is finished"

Look at this: http://phpjs.org/functions/index and find for print_r or use console.log() with firebug.

Here is my solution. The code should be easy enough to follow but here is the idea:

• get all inputs, selects, and textareas
• filter out all buttons and hidden fields
• filter to only enabled, visible fields
• select the first one
• focus the selected field

The code:

function focusFirst(parent) {
    $(parent).find('input, textarea, select')
        .not('input[type=hidden],input[type=button],input[type=submit],input[type=reset],input[type=image],button')
        .filter(':enabled:visible:first')
        .focus();
}

Then simply call focusFirst with your parent element or selector.

Selector:

focusFirst('form#aspnetForm');

Element:

var el = $('form#aspnetForm');
focusFirst(el);

And if you need to do it on items that match a specific condition...

double total = myList.Where(item => item.Name == "Eggs").Sum(item => item.Amount);

My opinions:

Q. When is it appropriate to use const in place of var?
A. Never!

Q: Should it be used every time a variable which is not going to be re-assigned is declared?
A: Never! Like this is going to make a dent in resource consumption...

Q. Does it actually make any difference if var is used in place of const or vice-versa?
A: Yes! Using var is the way to go! Much easier in dev tools and save from creating a new file(s) for testing. (var in not in place of const - const is trying to take var's place...)

Extra A: Same goes for let. JavaScript is a loose language - why constrict it?!?

If you use the Connect to Database under tools in Visual Studio, you will be able to add the name of the Server and database and test the connection. Upon success you can copy the string from the bottom of the dialog.

Making @sulai suggestion more generic :

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
        asyncTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
    else
        asyncTask.execute(params);
}   

Here is my function to draw multiple lines of text center in canvas (only break the line, don't break-word)

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");

let text = "Hello World \n Hello World 2222 \n AAAAA \n thisisaveryveryveryveryveryverylongword. "
ctx.font = "20px Arial";

fillTextCenter(ctx, text, 0, 0, c.width, c.height)

function fillTextCenter(ctx, text, x, y, width, height) {
    ctx.textBaseline = 'middle';
    ctx.textAlign = "center";

    const lines = text.match(/[^\r\n]+/g);
    for(let i = 0; i < lines.length; i++) {
        let xL = (width - x) / 2
        let yL =  y + (height / (lines.length + 1)) * (i+1)

        ctx.fillText(lines[i], xL, yL)
    }
}

<canvas id="myCanvas" width="300" height="150" style="border:1px solid #000;"></canvas>

conio.h is a C header file used in old MS-DOS compilers to create text user interfaces. Compilers that targeted non-DOS operating systems, such as Linux, Win32 and OS/2, provided different implementations of these functions.

The #include <curses.h> will give you almost all the functionalities that was provided in conio.h

You should put your model class before create_all() call, like this:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    email = db.Column(db.String(120), unique=True)

    def __init__(self, username, email):
        self.username = username
        self.email = email

    def __repr__(self):
        return '<User %r>' % self.username

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

If your models are declared in a separate module, import them before calling create_all().

Say, the User model is in a file called models.py,

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

# See important note below
from models import User

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

Important note: It is important that you import your models after initializing the db object since, in your models.py _you also need to import the db object from this module.

This solution uses an Asynchronous call. It will likely work better than a synchronous solution.

var request = new XMLHttpRequest();
request.open("GET", "../../data/file.json", false);
request.send(null);
request.onreadystatechange = function() {
  if ( request.readyState === 4 && request.status === 200 ) {
    var my_JSON_object = JSON.parse(request.responseText);
    console.log(my_JSON_object);
  }
}

You can do this by using Apace common lang package (org.apache.commons.lang.ArrayUtils class ). You need to do the following

byte[] concatBytes = ArrayUtils.addAll(one,two);

#!/bin/bash
ping_count="4"
avg_max_limit="1500"
router="sagemcom-fast-2804-v2"
adress="192.168.1.1"
user="admin"
pass="admin"

VAR=$(
expect -c " 
        set timeout 3
        spawn telnet "$adress"
        expect \"Login:\" 
        send \"$user\n\"
        expect \"Password:\"
        send \"$pass\n\"
        expect \"commands.\"
        send \"ping ya.ru -c $ping_count\n\"
        set timeout 9
        expect \"transmitted\"
        send \"exit\"
        ")

count_ping=$(echo "$VAR" | grep packets | cut -c 1)
avg_ms=$(echo "$VAR" | grep round-trip | cut -d '/' -f 4 | cut -d '.' -f 1)

echo "1_____ping___$count_ping|||____$avg_ms"
echo "$VAR"

You will need to enable logging of these events. Do so by opening the group policy editor:

run -> gpedit.msc

and configuring the following category:

Computer Configuration ->
Windows Settings ->
Security Settings ->
Advanced Audit Policy Configuration ->
System Audit Policies - Local Group Policy Object ->
Logon/Logoff ->
Audit Other Login/Logoff Events

(In the Explain tab it says "... allows you to audit ... Locking and unlocking a workstation".)

The main advantages are syntactic:

• More declarative/compact syntax
• ES6 modules will basically make UMD (Universal Module Definition) obsolete - essentially removes the schism between CommonJS and AMD (server vs browser).

You are unlikely to see any performance benefits with ES6 modules. You will still need an extra library to bundle the modules, even when there is full support for ES6 features in the browser.

To treat all compiler warnings as compilation errors

1. With a project selected in Solution Explorer, on the Project menu, click Properties.
2. Click the Compile tab. (or Build Tab may be there)
3. Select the Treat all warnings as errors check box. (or select the build setting and change the “treat warnings as errors” settings to true.)

and if you want to get rid of it

To disable all compiler warnings

1. With a project selected in Solution Explorer, on the Project menu click Properties.
2. Click the Compile tab. (or Build Tab may be there)
3. Select the Disable all warnings check box. (or select the build setting and change the “treat warnings as errors” settings to false.)

Modern browsers support 'DOUBLE VERTICAL BAR' (U+23F8), too:

http://www.fileformat.info/info/unicode/char/23f8/index.htm

For a music player it can act as a companion for 'BLACK RIGHT-POINTING POINTER' (U+25BA) because they both share equal width and height making it perfect for a play/pause button:

http://www.fileformat.info/info/unicode/char/25ba/index.htm

Or just use $json as an object:

$json->$user = array("first" => $first, "last" => $last);

This is how it is returned without the second parameter (as an instance of stdClass).

Declare

public static int[] locations={1,2,3};

outside of the main method.

As of Jackson 2.0, @JsonSerialize(include = xxx) has been deprecated in favour of @JsonInclude

Here is the Java 8+ example:

public static void pack(String sourceDirPath, String zipFilePath) throws IOException {
    Path p = Files.createFile(Paths.get(zipFilePath));
    try (ZipOutputStream zs = new ZipOutputStream(Files.newOutputStream(p))) {
        Path pp = Paths.get(sourceDirPath);
        Files.walk(pp)
          .filter(path -> !Files.isDirectory(path))
          .forEach(path -> {
              ZipEntry zipEntry = new ZipEntry(pp.relativize(path).toString());
              try {
                  zs.putNextEntry(zipEntry);
                  Files.copy(path, zs);
                  zs.closeEntry();
            } catch (IOException e) {
                System.err.println(e);
            }
          });
    }
}

I think that this will do the trick:

table{
    table-layout: fixed;
    width: 300px;
}

Building on the other answers, I wanted to share an example of using the while loop construct to achieve a do-while behaviour. By using a simple boolean variable in the while condition (initialized to TRUE), and then checking our actual condition later in the if statement. One could also use a break keyword instead of the continue <- FALSE inside the if statement (probably more efficient).

  df <- data.frame(X=c(), R=c())  
  x <- x0
  continue <- TRUE

  while(continue)
  {
    xi <- (11 * x) %% 16
    df <- rbind(df, data.frame(X=x, R=xi))
    x <- xi

    if(xi == x0)
    {
      continue <- FALSE
    }
  }

If you want a simple solution just to create and verify serial numbers, try Ellipter. It uses elliptic curves cryptography and has an "Expiration Date" feature so you can create trial verisons or time-limited registration keys.

Bootstrap has added a new class from 3.0.

<div class="text-center">
    <ul class="pagination">
        <li><a href="?p=0" data-original-title="" title="">1</a></li> 
        <li><a href="?p=1" data-original-title="" title="">2</a></li> 
    </ul>
</div>

Bootstrap 4 has new class

<div class="text-xs-center">
    <ul class="pagination">
        <li><a href="?p=0" data-original-title="" title="">1</a></li> 
        <li><a href="?p=1" data-original-title="" title="">2</a></li> 
    </ul>
</div>

For 2.3.2

<div class="pagination text-center">
    <ul>
        <li><a href="?p=0" data-original-title="" title="">1</a></li> 
        <li><a href="?p=1" data-original-title="" title="">2</a></li> 
    </ul>
</div>

Give this way:

.pagination {text-align: center;}

It works because ul is using inline-block;

Fiddle: http://jsfiddle.net/praveenscience/5L8fu/

Or if you would like to use Bootstrap's class:

<div class="pagination pagination-centered">
    <ul>
        <li><a href="?p=0" data-original-title="" title="">1</a></li> 
        <li><a href="?p=1" data-original-title="" title="">2</a></li> 
    </ul>
</div>

onProgressChanged is called every time you move the cursor.

@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
    textView.setText(String.valueOf(new Integer(progress)));        
}

so textView should show the progress and alter always if the seekbar is being moved.

For adding a RelativeLayout attribute whose value is true or false use 0 for false and RelativeLayout.TRUE for true:

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) button.getLayoutParams()
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE)

It doesn't matter whether or not the attribute was already added, you still use addRule(verb, subject) to enable/disable it. However, post-API 17 you can use removeRule(verb) which is just a shortcut for addRule(verb, 0).

It should be enough to do:

$this->validate($request, [
    'password' => 'sometimes,min:6,confirmed,required_with:password_confirmed',
]);

Make password optional, but if present requires a password_confirmation that matches, also make password required only if password_confirmed is present

You're trying to create a tuple, but you're just parenthesizing a string :)

Add an extra ',':

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=(dRecieved,))  # <- note extra ','
processThread.start()

Or use brackets to make a list:

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=[dRecieved])  # <- 1 element list
processThread.start()

If you notice, from the stack trace: self.__target(*self.__args, **self.__kwargs)

The *self.__args turns your string into a list of characters, passing them to the processLine function. If you pass it a one element list, it will pass that element as the first argument - in your case, the string.

How to put MySQL functions back into PHP 7
Step 1

First get the mysql extension source which was removed in March:

https://github.com/php/php-src/tree/PRE_PHP7_EREG_MYSQL_REMOVALS/ext/mysql

Step 2

Then edit your php.ini

Somewhere either in the “Extensions” section or “MySQL” section, simply add this line:

extension = /usr/local/lib/php/extensions/no-debug-non-zts-20141001/mysql.so

Step 3

Restart PHP and mysql_* functions should now be working again.

Step 4

Turn off all deprecated warnings including them from mysql_*:

error_reporting(E_ALL ^ E_DEPRECATED);

Now Below Code Help You :

$result = mysql_query("SELECT names FROM Customers");
$Data= Array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) 
{
        $Data[] =  $row['names'];  
}

You can also get all values in column using mysql_fetch_assoc

$result = mysql_query("SELECT names FROM Customers");
    $Data= Array();
    while ($row = mysql_fetch_assoc($result)) 
    {
            $Data[] =  $row['names'];  
    }

This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.

Reference

YOU CAN USE MYSQLI ALTERNATIVE OF MYSQL EASY WAY

*

<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

$sql="SELECT Lastname,Age FROM Persons ORDER BY Lastname";
$result=mysqli_query($con,$sql);

// Numeric array
$row=mysqli_fetch_array($result,MYSQLI_NUM);
printf ("%s (%s)\n",$row[0],$row[1]);

// Associative array
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);
printf ("%s (%s)\n",$row["Lastname"],$row["Age"]);

// Free result set
mysqli_free_result($result);

mysqli_close($con);
?> 

Had a similar issue. But it is important to understand the root cause and it may vary for different use cases.

Scenario 1
You are trying to decrypt a value which was not encoded correctly in the first place.

byte[] encryptedBytes = Base64.decodeBase64(encryptedBase64String);

If the String is misconfigured for certain reason or has not been encoded correctly, you would see the error " Input length must be multiple of 16 when decrypting with padded cipher"

Scenario 2
Now if by any chance you are using this encoded string in url (trying to pass in the base64Encoded value in url, it will fail. You should do URLEncoding and then pass in the token, it will work.

Scenario 3
When integrating with one of the vendors, we found that we had to do encryption of Base64 using URLEncoder but then we need not decode it because it was done internally by the Vendor

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

You can disable the Rollback:

@TransactionConfiguration(defaultRollback = false)

Example:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@Transactional
@TransactionConfiguration(defaultRollback = false)
public class Test {
    @PersistenceContext
    private EntityManager em;

    @org.junit.Test
    public void menge() {
        PersistentObject object = new PersistentObject();
        em.persist(object);
        em.flush();
    }
}

If you have PHP 7.0:

The simple and most effective way is with assignment inside brackets.

The rule is simple: Do you use your variable more than once? Then declare it the first time it's used within brackets, keep calm and carry on.

@if(($users = User::all())->count())
  @foreach($users as $user)
    {{ $user->name }}
  @endforeach
@else
  There are no users.
@endif

And yes, I know about @forelse, this is just a demo.

Since your variables are now declared as and when they are used, there is no need for any blade workarounds.

i think you should use hidden better.

activityIndicator.hidden = YES

just remove and reDownload wrapper gradle.

Mac Home/.gradle/wrapper/dists/

remove gradle version and sync gradle in project and run project.

Yes, that is safe and recommended.

The only caveat from the page you referred is that you can't be modifying configuration of the mapper once it is shared; but you are not changing configuration so that is fine. If you did need to change configuration, you would do that from the static block and it would be fine as well.

EDIT: (2013/10)

With 2.0 and above, above can be augmented by noting that there is an even better way: use ObjectWriter and ObjectReader objects, which can be constructed by ObjectMapper. They are fully immutable, thread-safe, meaning that it is not even theoretically possible to cause thread-safety issues (which can occur with ObjectMapper if code tries to re-configure instance).

Once you write the c# code and save it. You can use the command prompt to execute it just like the other code.

In command prompt you enter the directory your file is in and type

To Compile:

mcs yourfilename.cs

To Execute:

mono yourfilename.exe 

if you want your .exe file to be different with a different name, type

To Compile:

mcs yourfilename.cs -out:anyname.exe 

To Execute:

mono anyname.exe 

This should help!

I am not sure if you got this resolved. To follow up on "CommonsWare's" comment.

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.

Change

Uri uri=Uri.parse("/external/images/media/470939");

to

Uri uri=Uri.parse("content://external/images/media/470939");

in my case

Uri uri = Uri.parse("content://media/external/images/media/6562");

date -d "25 JUN 2011" +%Y%m%d

outputs

20110625

You could also achieve that by renaming the columns:

df.columns = ['a', 'b']

This involves a manual step but could be an option especially if you would eventually rename your data frame.

Using the JDK, jar -tf will list the files in the jar. javap will give you more details from a particular class file.

Here comes a solution with XSLT:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="//element3">
    <xsl:value-of select="element4/text()" />.<xsl:value-of select="element5/text()" />
</xsl:template>
</xsl:stylesheet>

Either Cast or Convert:

Syntax for CAST:

CAST ( expression AS data_type [ (length ) ])

Syntax for CONVERT:

CONVERT ( data_type [ ( length ) ] , expression [ , style ] )

Actually since you asked for a specific format:

REPLACE(CONVERT(varchar(10), Date, 102), '.', '-')

You should always annotate methods with @Override if it's available.

In JDK 5 this means overriding methods of superclasses, in JDK 6, and 7 it means overriding methods of superclasses, and implementing methods of interfaces. The reason, as mentioned previously, is it allows the compiler to catch errors where you think you are overriding (or implementing) a method, but are actually defining a new method (different signature).

The equals(Object) vs. equals(YourObject) example is a standard case in point, but the same argument can be made for interface implementations.

I'd imagine the reason it's not mandatory to annotate implementing methods of interfaces is that JDK 5 flagged this as a compile error. If JDK 6 made this annotation mandatory, it would break backwards compatibility.

I am not an Eclipse user, but in other IDEs (IntelliJ), the @Override annotation is only added when implementing interface methods if the project is set as a JDK 6+ project. I would imagine that Eclipse is similar.

However, I would have preferred to see a different annotation for this usage, maybe an @Implements annotation.

If the top commit is pointed to by HEAD then you can do something like this:

commit1 -> HEAD
commit2 -> HEAD~1
commit3 -> HEAD~2

Diff between the first and second commit:

git diff HEAD~1 HEAD

Diff between first and third commit:

git diff HEAD~2 HEAD

Diff between second and third commit:

git diff HEAD~2 HEAD~1

And so on...

try os.path.exists this will check for the path and return True if exists and False if not.

If the user is interacting with another application, it may not be possible to bring yours to the front. As a general rule, a process can only expect to set the foreground window if that process is already the foreground process. (Microsoft documents the restrictions in the SetForegroundWindow() MSDN entry.) This is because:

1. The user "owns" the foreground. For example, it would be extremely annoying if another program stole the foreground while the user is typing, at the very least interrupting her workflow, and possibly causing unintended consequences as her keystrokes meant for one application are misinterpreted by the offender until she notices the change.
2. Imagine that each of two programs checks to see if its window is the foreground and attempts to set it to the foreground if it is not. As soon as the second program is running, the computer is rendered useless as the foreground bounces between the two at every task switch.

In Swift 3, you can simply change the title of a button by:

button.setTitle("Title", for: .normal)

and you disable the button by:

button.isEnabled = false

.normal is the same as UIControlState.normal because the type is inferred.

This exact example is present on mozilla developers page:

::after

As you can see it even allows you to create tooltips! :) Also, instead of embedding the actual text in your CSS, you may use content: attr(data-descr);, and store it in data-descr="ADD" attribute of your HTML tag (which is nice because you can e.g translate it)

CSS content can only be usef with :after and :before pseudo-elements, so you can try to proceed with something like this:

.item a p.new-label span:after{
  position: relative;
  content: 'NEW'
}
.item:hover a p.new-label span:after {
  content: 'ADD';
}

The CSS :after pseudo-element matches a virtual last child of the selected element. Typically used to add cosmetic content to an element, by using the content CSS property. This element is inline by default.

Sorry for the necro-add, but there's something I really wanted to insert that's missing in the existing answers (for anyone like me stumbling onto this question via google): refactor your code. Not only will it make it easier to read/maintain, but it'll often remove these types of control-routing issues entirely.

Here's what I'd lean towards if I had to program the function above:

private const string CatchupLineToIndicateLogDump = "mp4:production/CATCHUP/";
private const string BatchFileLocation = "Command.bat";

private void CheckLog()
{
    while (true)
    {
        Thread.Sleep(5000);
        if (System.IO.File.Exists(BatchFileLocation))
        {
            if (doesFileContainStr(BatchFileLocation, CatchupLineToIndicateLogDump))
            {
                RemoveLogAndDump();
                return;
            }
        }
    }
}

private bool doesFileContainStr(string FileLoc, string StrToCheckFor)
{
  // ... code for checking the existing of a string within a file
  // (and returning back whether the string was found.)
}

private void RemoveLogAndDump()
{
  // ... your code to call RemoveEXELog and kick off test.exe
}

Swift

If you are not using object then you can user this code for contains.

let elements = [ 10, 20, 30, 40, 50]

if elements.contains(50) {

   print("true")

}

If you are using NSObject Class in swift. This variables is according to my requirement. you can modify for your requirement.

var cliectScreenList = [ATModelLeadInfo]()
var cliectScreenSelectedObject: ATModelLeadInfo!

This is for a same data type.

{ $0.user_id == cliectScreenSelectedObject.user_id }

If you want to AnyObject type.

{ "\($0.user_id)" == "\(cliectScreenSelectedObject.user_id)" }

Full condition

if cliectScreenSelected.contains( { $0.user_id == cliectScreenSelectedObject.user_id } ) == false {

    cliectScreenSelected.append(cliectScreenSelectedObject)

    print("Object Added")

} else {

    print("Object already exists")

 }

The output is actually dependent on the content type being requested. However, at minimum you should put the resource that was created in Location. Just like the Post-Redirect-Get pattern.

In my case I leave it blank until requested otherwise. Since that is the behavior of JAX-RS when using Response.created().

However, just note that browsers and frameworks like Angular do not follow 201's automatically. I have noted the behaviour in http://www.trajano.net/2013/05/201-created-with-angular-resource/

In my somewhat checkered experience, applying -O3 to an entire program almost always makes it slower (relative to -O2), because it turns on aggressive loop unrolling and inlining that make the program no longer fit in the instruction cache. For larger programs, this can also be true for -O2 relative to -Os!

The intended use pattern for -O3 is, after profiling your program, you manually apply it to a small handful of files containing critical inner loops that actually benefit from these aggressive space-for-speed tradeoffs. Newer versions of GCC have a profile-guided optimization mode that can (IIUC) selectively apply the -O3 optimizations to hot functions -- effectively automating this process.

Define function in protocol and create extension for that protocol, then create empty implementation for function which you want to use as optional.

If you want to do it using DF, you could use a udf to add a new column based on existing columns.

val sqlContext = new SQLContext(sc)
case class MyDf(col1: String, col2: String)

//here is our dataframe
val df = sqlContext.createDataFrame(sc.parallelize(
    Array(MyDf("A", "B"), MyDf("C", "D"), MyDf("E", "F"))
))

//Define a udf to concatenate two passed in string values
val getConcatenated = udf( (first: String, second: String) => { first + " " + second } )

//use withColumn method to add a new column called newColName
df.withColumn("newColName", getConcatenated($"col1", $"col2")).select("newColName", "col1", "col2").show()

You could do this using SUMIF. This allows you to SUM a value in a cell IF a value in another cell meets the specified criteria. Here's an example:

 -   A         B
 1   100       YES
 2   100       YES
 3   100       NO

Using the formula: =SUMIF(B1:B3, "YES", A1:A3), you will get the result of 200.

Here's a screenshot of a working example I just did in Excel:

How about:

(sleep 5; echo "Hello World") &

I just want to add something here: changing the title via JavaScript is actually useful if you're updating a database via AJAX, so then the title changes without you having to refresh the page. The title actually changes via your server side scripting language, but having it change via JavaScript is just a usability and UI thing that makes the user experience more enjoyable and fluid.

Now, if you're changing the title via JavaScript just for the hell of it, then you should not be doing that.

Do nothing to the browser. CORS is supported by default on all modern browsers (and since Firefox 3.5).

The server being accessed by JavaScript has to give the site hosting the HTML document in which the JS is running permission via CORS HTTP response headers.

security.fileuri.strict_origin_policy is used to give JS in local HTML documents access to your entire hard disk. Don't set it to false as it makes you vulnerable to attacks from downloaded HTML documents (including email attachments).

Some code I've worked with in the past used global variables just to avoid passing too many parameters around.

Please don't do that!

(Usually.)

Is this what you mean?

SELECT DISTINCT C.valueC
FROM 
C
INNER JOIN B ON C.id = B.lookupC
INNER JOIN A ON B.id = A.lookupB

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

Unlike another programming languages, any variable declared outside any function automatically becomes global,

<script>

//declare global variable
var __foo = '123';

function __test(){
 //__foo is global and visible here
 alert(__foo);
}

//so, it will alert '123'
__test();

</script>

You problem is that you declare variable inside ready() function, which means that it becomes visible (in scope) ONLY inside ready() function, but not outside,

Solution: So just make it global, i.e declare this one outside $(document).ready(function(){});

This is for all people who need to increase the radius of ScriptIntrinsicBlur to obtain a harder gaussian blur.

Instead of to put the radius more than 25, you can scale down the image and get the same result. I wrote a class called GaussianBlur. Below you can see how to use, and the whole class implementation.

Usage:

GaussianBlur gaussian = new GaussianBlur(context);
gaussian.setMaxImageSize(60);
gaussian.setRadius(25); //max

Bitmap output = gaussian.render(<your bitmap>,true);
Drawable d = new BitmapDrawable(getResources(),output);

Class:

 public class GaussianBlur {
    private final int DEFAULT_RADIUS = 25;
    private final float DEFAULT_MAX_IMAGE_SIZE = 400;

    private Context context;
    private int radius;
    private float maxImageSize;

    public GaussianBlur(Context context) {
    this.context = context;
    setRadius(DEFAULT_RADIUS);
    setMaxImageSize(DEFAULT_MAX_IMAGE_SIZE);
    } 

    public Bitmap render(Bitmap bitmap, boolean scaleDown) {
    RenderScript rs = RenderScript.create(context);

    if (scaleDown) {
        bitmap = scaleDown(bitmap);
    }

    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Config.ARGB_8888);

    Allocation inAlloc = Allocation.createFromBitmap(rs, bitmap, Allocation.MipmapControl.MIPMAP_NONE, Allocation.USAGE_GRAPHICS_TEXTURE);
    Allocation outAlloc = Allocation.createFromBitmap(rs, output);

    ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, inAlloc.getElement()); // Element.U8_4(rs));
    script.setRadius(getRadius());
    script.setInput(inAlloc);
    script.forEach(outAlloc);
    outAlloc.copyTo(output);

    rs.destroy();

    return output;
}

public Bitmap scaleDown(Bitmap input) {
    float ratio = Math.min((float) getMaxImageSize() / input.getWidth(), (float) getMaxImageSize() / input.getHeight());
    int width = Math.round((float) ratio * input.getWidth());
    int height = Math.round((float) ratio * input.getHeight());

    return Bitmap.createScaledBitmap(input, width, height, true);
}

public int getRadius() {
    return radius;
}

public void setRadius(int radius) {
    this.radius = radius;
}

public float getMaxImageSize() {
    return maxImageSize;
}

public void setMaxImageSize(float maxImageSize) {
    this.maxImageSize = maxImageSize;
}
    }

I think the Default place for IIS logging is: c:\inetpub\wwwroot\log\w3svc

Neither. You set the isolation level to READ UNCOMMITTED which is always better than giving individual lock hints. Or, better still, if you care about details like consistency, use snapshot isolation.

It's Python; anything goes. Consider how to publish your documentation. Docstrings are invisible except to readers of your source code.

People really like to browse and search documentation on the web. To achieve that, use the documentation tool Sphinx. It's the de-facto standard for documenting Python projects. The product is beautiful - take a look at https://python-guide.readthedocs.org/en/latest/ . The website Read the Docs will host your docs for free.

You'd have to define alphanumerics exactly, but

/^(\w{3,5})$/ 

Should match any digit/character/_ combination of length 3-5.

If you also need the dash, make sure to escape it (\-) add it, like this: :

/^([\w\-]{3,5})$/ 

Also: the ^ anchor means that the sequence has to start at the beginning of the line (character string), and the $ that it ends at the end of the line (character string). So your value string mustn't contain anything else, or it won't match.

I came across this post looking for a "shaking" implementation. millenomi's answer worked well for me, although i was looking for something that required a bit more "shaking action" to trigger. I've replaced to Boolean value with an int shakeCount. I also reimplemented the L0AccelerationIsShaking() method in Objective-C. You can tweak the ammount of shaking required by tweaking the ammount added to shakeCount. I'm not sure i've found the optimal values yet, but it seems to be working well so far. Hope this helps someone:

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {
    if (self.lastAcceleration) {
        if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7] && shakeCount >= 9) {
            //Shaking here, DO stuff.
            shakeCount = 0;
        } else if ([self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.7]) {
            shakeCount = shakeCount + 5;
        }else if (![self AccelerationIsShakingLast:self.lastAcceleration current:acceleration threshold:0.2]) {
            if (shakeCount > 0) {
                shakeCount--;
            }
        }
    }
    self.lastAcceleration = acceleration;
}

- (BOOL) AccelerationIsShakingLast:(UIAcceleration *)last current:(UIAcceleration *)current threshold:(double)threshold {
    double
    deltaX = fabs(last.x - current.x),
    deltaY = fabs(last.y - current.y),
    deltaZ = fabs(last.z - current.z);

    return
    (deltaX > threshold && deltaY > threshold) ||
    (deltaX > threshold && deltaZ > threshold) ||
    (deltaY > threshold && deltaZ > threshold);
}

Another interesting way to quickly repeat n character is to use idea from quick exponentiation algorithm:

var repeatString = function(string, n) {
    var result = '', i;

    for (i = 1; i <= n; i *= 2) {
        if ((n & i) === i) {
            result += string;
        }
        string = string + string;
    }

    return result;
};

An extension to what GenericTypeTea says - Here is a concrete example:

<form onsubmit="return false">

The above form will not submit, whereas...

<form onsubmit="false">

...does nothing, i.e. the form will submit.

Without the return, onsubmit doesn't receive a value and the event is executed just like without any handler at all.

As jzd says, you can use System.currentTimeMillis. If you need it in a Date object but don't want to create a new Date object, you can use Date.setTime to reuse an existing Date object. Personally I hate the fact that Date is mutable, but maybe it's useful to you in this particular case. Similarly, Calendar has a setTimeInMillis method.

If possible though, it would probably be better just to keep it as a long. If you only need a timestamp, effectively, then that would be the best approach.

Main Difference Between PUT and PATCH Requests:

Suppose we have a resource that holds the first name and last name of a person.

If we want to change the first name then we send a put request for Update

{ "first": "Michael", "last": "Angelo" }

Here, although we are only changing the first name, with PUT request we have to send both parameters first and last.
In other words, it is mandatory to send all values again, the full payload.

When we send a PATCH request, however, we only send the data which we want to update. In other words, we only send the first name to update, no need to send the last name.

Here is a way which allows to remove points after a certain number of points plotted:

import matplotlib.pyplot as plt
# generate axes object
ax = plt.axes()

# set limits
plt.xlim(0,10) 
plt.ylim(0,10)

for i in range(10):        
     # add something to axes    
     ax.scatter([i], [i]) 
     ax.plot([i], [i+1], 'rx')

     # draw the plot
     plt.draw() 
     plt.pause(0.01) #is necessary for the plot to update for some reason

     # start removing points if you don't want all shown
     if i>2:
         ax.lines[0].remove()
         ax.collections[0].remove()

$(document).ready(function() {
  //...
//clear on focus
$('.input').focus(function() {
    $('.input').val("");
});
   //clear when submitted
$('.button').click(function() {
    $('.input').val("");
});

});

The best way is to use spyOnProperty. It expects 3 parameters and you need to pass get or set as a third param.

Example

const div = fixture.debugElement.query(By.css('.ellipsis-overflow'));
// now mock properties
spyOnProperty(div.nativeElement, 'clientWidth', 'get').and.returnValue(1400);
spyOnProperty(div.nativeElement, 'scrollWidth', 'get').and.returnValue(2400);

Here I am setting the get of clientWidth of div.nativeElement object.

I haven't found any solution using Google's Closure library. So just to complete the list for future vistors, here's how you load a JSON from local file with Closure library:

goog.net.XhrIo.send('../appData.json', function(evt) {
  var xhr = evt.target;
  var obj = xhr.getResponseJson(); //JSON parsed as Javascript object
  console.log(obj);
});

Multiple columns in a key are going to, in general, perform more poorly than a surrogate key. I prefer to have a surrogate key and then a unique index on a multicolumn key. That way you can have better performance and the uniqueness needed is maintained. And even better, when one of the values in that key changes, you don't also have to update a million child entries in 215 child tables.

I'd like to add some notes about the differences between Func<T> and Expression<Func<T>>:

• Func<T> is just a normal old-school MulticastDelegate;
• Expression<Func<T>> is a representation of lambda expression in form of expression tree;
• expression tree can be constructed through lambda expression syntax or through the API syntax;
• expression tree can be compiled to a delegate Func<T>;
• the inverse conversion is theoretically possible, but it's a kind of decompiling, there is no builtin functionality for that as it's not a straightforward process;
• expression tree can be observed/translated/modified through the ExpressionVisitor;
• the extension methods for IEnumerable operate with Func<T>;
• the extension methods for IQueryable operate with Expression<Func<T>>.

There's an article which describes the details with code samples:
LINQ: Func<T> vs. Expression<Func<T>>.

Hope it will be helpful.

Intellisense did not recognized an imported namespace in my case, although I could compile the project successfully. The solution was to uncheck imported namespace on project references tab, save the project, check it again and save the project again.

I faced this problem in vs 2017 update 3 with Resharper Ultimate 2017.2

Restart vs or restart machine can't help.

I resolved the problem by clearing the Cache as follows:

    Resharper ->options-> Environment ->click the button 'Clear caches'

Update:

There is a button "error" (I find in Resharper 2018) in the upper right corner of the test window.

If you click the error button, it shows an error message that may help in resolving the problem.

To track the root of the problem, run Visual Studio in log mode. In vs 2017, Run the command:

      devenv /ReSharper.LogFile C:\temp\log\test_log.txt /ReSharper.LogLevel Verbose

Run the test.

Review the log file test_log.txt and search for 'error' in the file.

The log file is a great help to find the error that you can resolve or you can send the issue with the log file to the technical support team of Resharper.

C++98 and C++03

This answer is for the older versions of the C++ standard. The C++11 and C++14 versions of the standard do not formally contain 'sequence points'; operations are 'sequenced before' or 'unsequenced' or 'indeterminately sequenced' instead. The net effect is essentially the same, but the terminology is different.

Disclaimer : Okay. This answer is a bit long. So have patience while reading it. If you already know these things, reading them again won't make you crazy.

Pre-requisites : An elementary knowledge of C++ Standard

What are Sequence Points?

The Standard says

At certain specified points in the execution sequence called sequence points, all side effects of previous evaluations shall be complete and no side effects of subsequent evaluations shall have taken place. (§1.9/7)

Side effects? What are side effects?

Evaluation of an expression produces something and if in addition there is a change in the state of the execution environment it is said that the expression (its evaluation) has some side effect(s).

For example:

int x = y++; //where y is also an int

In addition to the initialization operation the value of y gets changed due to the side effect of ++ operator.

So far so good. Moving on to sequence points. An alternation definition of seq-points given by the comp.lang.c author Steve Summit:

Sequence point is a point in time at which the dust has settled and all side effects which have been seen so far are guaranteed to be complete.

What are the common sequence points listed in the C++ Standard ?

Those are:

• at the end of the evaluation of full expression (§1.9/16) (A full-expression is an expression that is not a subexpression of another expression.)¹

  Example :

  int a = 5; // ; is a sequence point here
  

• in the evaluation of each of the following expressions after the evaluation of the first expression (§1.9/18) ²

  • a && b (§5.14)
  • a || b (§5.15)
  • a ? b : c (§5.16)
  • a , b (§5.18) (here a , b is a comma operator; in func(a,a++) , is not a comma operator, it's merely a separator between the arguments a and a++. Thus the behaviour is undefined in that case (if a is considered to be a primitive type))
    

• at a function call (whether or not the function is inline), after the evaluation of all function arguments (if any) which takes place before execution of any expressions or statements in the function body (§1.9/17).

_{1 : Note : the evaluation of a full-expression can include the evaluation of subexpressions that are not lexically part of the full-expression. For example, subexpressions involved in evaluating default argument expressions (8.3.6) are considered to be created in the expression that calls the function, not the expression that defines the default argument}

_{2 : The operators indicated are the built-in operators, as described in clause 5. When one of these operators is overloaded (clause 13) in a valid context, thus designating a user-defined operator function, the expression designates a function invocation and the operands form an argument list, without an implied sequence point between them.}

What is Undefined Behaviour?

The Standard defines Undefined Behaviour in Section §1.3.12 as

behavior, such as might arise upon use of an erroneous program construct or erroneous data, for which this International Standard imposes no requirements ³.

Undefined behavior may also be expected when this International Standard omits the description of any explicit definition of behavior.

_{3 : permissible undefined behavior ranges from ignoring the situation completely with unpredictable results, to behaving during translation or program execution in a documented manner characteristic of the environment (with or with- out the issuance of a diagnostic message), to terminating a translation or execution (with the issuance of a diagnostic message).}

In short, undefined behaviour means anything can happen from daemons flying out of your nose to your girlfriend getting pregnant.

What is the relation between Undefined Behaviour and Sequence Points?

Before I get into that you must know the difference(s) between Undefined Behaviour, Unspecified Behaviour and Implementation Defined Behaviour.

You must also know that the order of evaluation of operands of individual operators and subexpressions of individual expressions, and the order in which side effects take place, is unspecified.

For example:

int x = 5, y = 6;

int z = x++ + y++; //it is unspecified whether x++ or y++ will be evaluated first.

Another example here.

Now the Standard in §5/4 says

• 1) Between the previous and next sequence point a scalar object shall have its stored value modified at most once by the evaluation of an expression.

What does it mean?

Informally it means that between two sequence points a variable must not be modified more than once. In an expression statement, the next sequence point is usually at the terminating semicolon, and the previous sequence point is at the end of the previous statement. An expression may also contain intermediate sequence points.

From the above sentence the following expressions invoke Undefined Behaviour:

i++ * ++i;   // UB, i is modified more than once btw two SPs
i = ++i;     // UB, same as above
++i = 2;     // UB, same as above
i = ++i + 1; // UB, same as above
++++++i;     // UB, parsed as (++(++(++i)))

i = (i, ++i, ++i); // UB, there's no SP between `++i` (right most) and assignment to `i` (`i` is modified more than once btw two SPs)

But the following expressions are fine:

i = (i, ++i, 1) + 1; // well defined (AFAIK)
i = (++i, i++, i);   // well defined 
int j = i;
j = (++i, i++, j*i); // well defined

• 2) Furthermore, the prior value shall be accessed only to determine the value to be stored.

What does it mean? It means if an object is written to within a full expression, any and all accesses to it within the same expression must be directly involved in the computation of the value to be written.

For example in i = i + 1 all the access of i (in L.H.S and in R.H.S) are directly involved in computation of the value to be written. So it is fine.

This rule effectively constrains legal expressions to those in which the accesses demonstrably precede the modification.

Example 1:

std::printf("%d %d", i,++i); // invokes Undefined Behaviour because of Rule no 2

Example 2:

a[i] = i++ // or a[++i] = i or a[i++] = ++i etc

is disallowed because one of the accesses of i (the one in a[i]) has nothing to do with the value which ends up being stored in i (which happens over in i++), and so there's no good way to define--either for our understanding or the compiler's--whether the access should take place before or after the incremented value is stored. So the behaviour is undefined.

Example 3 :

int x = i + i++ ;// Similar to above

Caveats

Here are two worthy caveats from the comments.

Either you want user to be of type User | {} or Partial<User>, or you need to redefine the User type to allow an empty object. Right now, the compiler is correctly telling you that user is not a User. – jcalz

I don't think this should be considered a proper answer because it creates an inconsistent instance of the type, undermining the whole purpose of TypeScript. In this example, the property Username is left undefined, while the type annotation is saying it can't be undefined. – Ian Liu Rodrigues

Answer

One of the design goals of TypeScript is to "strike a balance between correctness and productivity." If it will be productive for you to do this, use Type Assertions to create empty objects for typed variables.

type User = {
    Username: string;
    Email: string;
}

const user01 = {} as User;
const user02 = <User>{};

user01.Email = "[email protected]";

Here is a working example for you.

In HTML only:

<label>
  <input type="file" name="input-name" style="display: none;" />
  <span>Select file</span>
</label>

Edit: I hadn't tested this in Blink, it actually doesn't work with a <button>, but it should work with most other elements–at least in recent browsers.

Check this fiddle with the code above.

If you absolutely must use HTML to give your text color, you have to use the (deprecated) <font>-tag:

<h2><font color="#006699">Process Report</font></h2>

But otherwise, I strongly recommend you to do as rekire said: use CSS.

i faced this same, i check in in program and feature. there was an update has install for jdk1.8 which is not compatible with my old setting(jdk1.6.0) for ant in eclipse. I install that update. right now, my ant project is build success.

Try it, hope this will be helpful.

Sounds like you don't have the execute flag set on the file permissions, try:

chmod u+x program_name

With git show you can get a similar result. For look the commit (like it looks on git log view) with the list of files included in, use:

git show --name-only [commit-id_A]^..[commit-id_B]

Where [commit-id_A] is the initial commit and [commit-id_B] is the last commit than you want to show.

Special attention with ^ symbol. If you don't put that, the commit-id_A information will not deploy.

You can also do it at run time as follows :

• Assign name to the window (x:Name = "HomePage")
• In constructor just set WindowState property to Maximized as follows

HomePage.WindowState = WindowState.Maximized;

Well in JavaScript you can check two strings for values same as integers so yo can do this:

• "A" < "B"
• "A" == "B"
• "A" > "B"

And therefore you can make your own function that checks strings the same way as the strcmp().

So this would be the function that does the same:

function strcmp(a, b)
{   
    return (a<b?-1:(a>b?1:0));  
}

There is a more 'smooth' solution for this :)

var Foo = function(){
  this.par = 3;

  this.sub = new(function(t){ //using virtual function to create sub object and pass parent object via 't'
    this.p = t;
    this.subFunction = function(){
      alert(this.p.par);
    }
  })(this);
}

var myObj = new Foo();
myObj.sub.subFunction() // will popup 3;

myObj.par = 5;
myObj.sub.subFunction() // will popup 5;

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

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

        var command = new SqlCommand(query, connection);

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

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

If you take a look at @types/node-fetch you will see the body definition

export class Body {
    bodyUsed: boolean;
    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

None of the above answers solved it for me.

I cant even find the 'libraries' folder in my xampp - ubuntu also.

So, I simply restarted using the following commands:

sudo service apache2 restart

and

sudo service mysql restart

Just restarted apache and mysql. Logged in phpmyadmin again and it worked as usual.

Thanks me..!!

os.system is equivalent to Unix system command, while subprocess was a helper module created to provide many of the facilities provided by the Popen commands with an easier and controllable interface. Those were designed similar to the Unix Popen command.

system() executes a command specified in command by calling /bin/sh -c command, and returns after the command has been completed

Whereas:

The popen() function opens a process by creating a pipe, forking, and invoking the shell.

If you are thinking which one to use, then use subprocess definitely because you have all the facilities for execution, plus additional control over the process.

Android UI programming is a little bit tricky. To enable the Options menu, in addition to the code you wrote, we also need to call setHasOptionsMenu(true) in your overriden method OnCreate(). Hope this will help you out.

Just put the html tags with there content and add the xmlns attribute with quotes after the equals and in between the quotes is http://www.w3.org/1999/xhtml

hope this will help you

let suppose we have a code like:

{
     int stackVariable = 1;

     blockName = ^()
     {
      stackVariable++;
     }
}

it will give an error like "variable is not assignable" because the stack variable inside the block are by default immutable.

adding __block(storage modifier) ahead of it declaration make it mutable inside the block i.e __block int stackVariable=1;

you can do this without jQuery:

    var form=document.getElementById('form-id');//retrieve the form as a DOM element

    var input = document.createElement('input');//prepare a new input DOM element
    input.setAttribute('name', inputName);//set the param name
    input.setAttribute('value', inputValue);//set the value
    input.setAttribute('type', inputType)//set the type, like "hidden" or other

    form.appendChild(input);//append the input to the form

    form.submit();//send with added input

Converting VARCHAR2 to CLOB

In PL/SQL a CLOB can be converted to a VARCHAR2 with a simple assignment, SUBSTR, and other methods. A simple assignment will only work if the CLOB is less then or equal to the size of the VARCHAR2. The limit is 32767 in PL/SQL and 4000 in SQL (although 12c allows 32767 in SQL).

For example, this code converts a small CLOB through a simple assignment and then coverts the beginning of a larger CLOB.

declare
    v_small_clob clob := lpad('0', 1000, '0');
    v_large_clob clob := lpad('0', 32767, '0') || lpad('0', 32767, '0');
    v_varchar2   varchar2(32767);
begin
    v_varchar2 := v_small_clob;
    v_varchar2 := substr(v_large_clob, 1, 32767);
end;

LONG?

The above code does not convert the value to a LONG. It merely looks that way because of limitations with PL/SQL debuggers and strings over 999 characters long.

For example, in PL/SQL Developer, open a Test window and add and debug the above code. Right-click on v_varchar2 and select "Add variable to Watches". Step through the code and the value will be set to "(Long Value)". There is a ... next to the text but it does not display the contents.

C#?

I suspect the real problem here is with C# but I don't know how enough about C# to debug the problem.

I had this issue and found Hasanavi's answer but I got a little bug when displaying the background image on a wide screen - The background image didn't spread to the whole width of the screen.

So here is my solution - based on Hasanavi's code but better... and this should work on both extra-wide and mobile screens.

/*WIDE SCREEN SUPPORT*/
@media screen and (min-width: 769px) { 
    div {
        background-image: url('http://www.pets4homes.co.uk/images/articles/1111/large/feline-influenza-all-about-cat-flu-5239fffd61ddf.jpg');
        background-size: cover;
        background-repeat: no-repeat;
        width: 100%;
        height: 0;
        padding-top: 66.64%; /* (img-height / img-width * container-width) */
                    /* (853 / 1280 * 100) */
    }
}

/*MOBILE SUPPORT*/
@media screen and (max-width: 768px) {
    div {
        background-image: url('http://www.pets4homes.co.uk/images/articles/1111/large/feline-influenza-all-about-cat-flu-5239fffd61ddf.jpg');
        background-size: contain;
        background-repeat: no-repeat;
        width: 100%;
        height: 0;
        padding-top: 66.64%; /* (img-height / img-width * container-width) */
                    /* (853 / 1280 * 100) */
    }
}

As you might have noticed, the background-size: contain; property doas not fit well in extra wide screens, and the background-size: cover; property does not fit well on mobile screens so I used this @media attribute to play around with the screen sizes and fix this issue.

env.OrderByDescending(x => x.ReportDate)

The stringr package provides the str_sub function, which is a bit easier to use than substr, especially if you want to extract right portions of your string :

R> str_sub("leftright",1,4)
[1] "left"
R> str_sub("leftright",-5,-1)
[1] "right"

dir /b *.jpg >file.bat

This will give you lines such as:

Vacation2010 001.jpg
Vacation2010 002.jpg
Vacation2010 003.jpg

Edit file.bat in your favorite Windows text-editor, doing the equivalent of:

s/Vacation2010(.+)/rename "&" "December \1"/

That's a regex; many editors support them, but none that come default with Windows (as far as I know). You can also get a command line tool such as sed or perl which can take the exact syntax I have above, after escaping for the command line.

The resulting lines will look like:

rename "Vacation2010 001.jpg" "December 001.jpg"
rename "Vacation2010 002.jpg" "December 002.jpg"
rename "Vacation2010 003.jpg" "December 003.jpg"

You may recognize these lines as rename commands, one per file from the original listing. ;) Run that batch file in cmd.exe.

Ids are meant to be unique, and never use an id that starts with a number, use data-attributes instead to set the target like so :

<div id="searchbycharacter">
    <a class="searchbychar" href="#" data-target="numeric">0-9 |</a> 
    <a class="searchbychar" href="#" data-target="A"> A |</a> 
    <a class="searchbychar" href="#" data-target="B"> B |</a> 
    <a class="searchbychar" href="#" data-target="C"> C |</a> 
    ... Untill Z
</div>

As for the jquery :

$(document).on('click','.searchbychar', function(event) {
    event.preventDefault();
    var target = "#" + this.getAttribute('data-target');
    $('html, body').animate({
        scrollTop: $(target).offset().top
    }, 2000);
});

Also, try the following example:

Xaml:

   <DataGrid AutoGenerateColumns="False" Name="DataGridTest" CanUserAddRows="True" ItemsSource="{Binding TestBinding}" Margin="0,50,0,0" >
        <DataGrid.Columns>
            <DataGridTextColumn Header="Line" IsReadOnly="True" Binding="{Binding Path=Test1}" Width="50"></DataGridTextColumn>
            <DataGridTextColumn Header="Account" IsReadOnly="True"  Binding="{Binding Path=Test2}" Width="130"></DataGridTextColumn>

I have done good research on the save() vs. persist() including running it on my local machine several times. All the previous explanations are confusing and incorrect. I compare save() and persist() methods below after a thorough research.

Save()

1. Returns generated Id after saving. Its return type is Serializable;
2. Saves the changes to the database outside of the transaction;
3. Assigns the generated id to the entity you are persisting;
4. session.save() for a detached object will create a new row in the table.

Persist()

1. Does not return generated Id after saving. Its return type is void;
2. Does not save the changes to the database outside of the transaction;
3. Assigns the generated Id to the entity you are persisting;
4. session.persist() for a detached object will throw a PersistentObjectException, as it is not allowed.

All these are tried/tested on Hibernate v4.0.1.

If it is because of the overhead in terms of creating objects, then it probably can't be sped up at all with SA.

If it is because it is loading up related objects, then you might be able to do something with lazy loading. Are there lots of objects being created due to references? (IE, getting a Company object also gets all of the related People objects).

Welcome to Microsoft Marketing Speak hell. With the 2012 release of SQL Server, the BIDS, Business Intelligence Designer Studio, plugin for Visual Studio was renamed to SSDT, SQL Server Data Tools. SSDT is available for 2010 and 2012. The problem is, there are two different products called SSDT.

There is SSDT which replaces the database designer thing which was called Data Dude in VS 2008 and in 2010 became database projects. That a free install and if you snag the web installer, that's what you get when you install SSDT. It puts the correct project templates and such into Visual Studio.

There's also the SSDT which is the "BIDS" replacement for developing SSIS, SSRS and SSAS stuff. As of March 2013, it is now available for the 2012 release of Visual Studio. The download is labeled SSDTBI_VS2012_X86.msi Perhaps that's a signal on how the product is going to be referred to in marketing materials. Download links are

• Microsoft SQL Server Data Tools Business Intelligence for Visual Studio 2012 (SSIS packages target SQL Server 2012)
• Microsoft SQL Server Data Tools Business Intelligence for Visual Studio 2013 (SSIS packages target SQL Server 2014)

None the less, we have Business Intelligence projects available to us in Visual Studio 2012. And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals

Here is a way to get the header titles from the column names dynamically.

/* Change table_name and database_name */
SET @table_name = 'table_name';
SET @table_schema = 'database_name';
SET @default_group_concat_max_len = (SELECT @@group_concat_max_len);

/* Sets Group Concat Max Limit larger for tables with a lot of columns */
SET SESSION group_concat_max_len = 1000000;

SET @col_names = (
  SELECT GROUP_CONCAT(QUOTE(`column_name`)) AS columns
  FROM information_schema.columns
  WHERE table_schema = @table_schema
  AND table_name = @table_name);

SET @cols = CONCAT('(SELECT ', @col_names, ')');

SET @query = CONCAT('(SELECT * FROM ', @table_schema, '.', @table_name,
  ' INTO OUTFILE \'/tmp/your_csv_file.csv\'
  FIELDS ENCLOSED BY \'\\\'\' TERMINATED BY \'\t\' ESCAPED BY \'\'
  LINES TERMINATED BY \'\n\')');

/* Concatenates column names to query */
SET @sql = CONCAT(@cols, ' UNION ALL ', @query);

/* Resets Group Contact Max Limit back to original value */
SET SESSION group_concat_max_len = @default_group_concat_max_len;

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Please refer to the following method. It takes your date String as argument1, you need to specify the existing format of the date as argument2, and the result (expected) format as argument 3.

Refer to this link to understand various formats: Available Date Formats

public static String formatDateFromOnetoAnother(String date,String givenformat,String resultformat) {

    String result = "";
    SimpleDateFormat sdf;
    SimpleDateFormat sdf1;

    try {
        sdf = new SimpleDateFormat(givenformat);
        sdf1 = new SimpleDateFormat(resultformat);
        result = sdf1.format(sdf.parse(date));
    }
    catch(Exception e) {
        e.printStackTrace();
        return "";
    }
    finally {
        sdf=null;
        sdf1=null;
    }
    return result;
}

I know this is an old question, but I think this is the definitive answer.

listViewRamos.Items[i].Focused = true;
listViewRamos.Items[i].Selected = true;
listViewRemos.Items[i].EnsureVisible();

If there is a chance the control does not have the focus but you want to force the focus to the control, then you can add the following line.

listViewRamos.Select();

Why Microsoft didn't just add a SelectItem() method that does all this for you is beyond me.

I would suggest looking at how browsers handle forms by default. For example take a look at the form element <select multiple> and how it handles multiple values from this example at w3schools.

<form action="/action_page.php">
<select name="cars" multiple>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="opel">Opel</option>
  <option value="audi">Audi</option>
</select>
<input type="submit">
</form>

For PHP use:

<select name="cars[]" multiple>

Live example from above at w3schools.com

From above if you click "saab, opel" and click submit, it will generate a result of cars=saab&cars=opel. Then depending on the back-end server, the parameter cars should come across as an array that you can further process.

Hope this helps anyone looking for a more 'standard' way of handling this issue.

you can use preload="none" in the attribute of video tag so the video will be displayed only when user clicks on play button.

<video preload="none">

You can do do it. The input type submit should be inside of a form. Then all you have to do is write the link you want to redirect to inside the action attribute that is inside the form tag.

This is happening because of the CORS error. CORS stands for Cross Origin Resource Sharing. In simple words, this error occurs when we try to access a domain/resource from another domain.

Read More about it here: CORS error with jquery

To fix this, if you have access to the other domain, you will have to allow Access-Control-Allow-Origin in the server. This can be added in the headers. You can enable this for all the requests/domains or a specific domain.

R has gotten to the point where the OS cannot allocate it another 75.1Mb chunk of RAM. That is the size of memory chunk required to do the next sub-operation. It is not a statement about the amount of contiguous RAM required to complete the entire process. By this point, all your available RAM is exhausted but you need more memory to continue and the OS is unable to make more RAM available to R.

Potential solutions to this are manifold. The obvious one is get hold of a 64-bit machine with more RAM. I forget the details but IIRC on 32-bit Windows, any single process can only use a limited amount of RAM (2GB?) and regardless Windows will retain a chunk of memory for itself, so the RAM available to R will be somewhat less than the 3.4Gb you have. On 64-bit Windows R will be able to use more RAM and the maximum amount of RAM you can fit/install will be increased.

If that is not possible, then consider an alternative approach; perhaps do your simulations in batches with the n per batch much smaller than N. That way you can draw a much smaller number of simulations, do whatever you wanted, collect results, then repeat this process until you have done sufficient simulations. You don't show what N is, but I suspect it is big, so try smaller N a number of times to give you N over-all.

Base URL in JavaScript

You can access the current url quite easily in JavaScript with window.location

You have access to the segments of that URL via this locations object. For example:

// This article:
// https://stackoverflow.com/questions/21246818/how-to-get-the-base-url-in-javascript

var base_url = window.location.origin;
// "http://stackoverflow.com"

var host = window.location.host;
// stackoverflow.com

var pathArray = window.location.pathname.split( '/' );
// ["", "questions", "21246818", "how-to-get-the-base-url-in-javascript"]

In Chrome Dev Tools, you can simply enter window.location in your console and it will return all of the available properties.

Check STR. You need something like SELECT STR([Column_Name],10,0) ** This is SQL Server solution, for other servers check their docs.

Using ggplot and a little dplyr for data manipulation:

set.seed(42)
df <- data.frame(x = rep(1:10,each=5), y = rnorm(50))

library(ggplot2)
library(dplyr)

df.summary <- df %>% group_by(x) %>%
    summarize(ymin = min(y),
              ymax = max(y),
              ymean = mean(y))

ggplot(df.summary, aes(x = x, y = ymean)) +
    geom_point(size = 2) +
    geom_errorbar(aes(ymin = ymin, ymax = ymax))

If there's an additional grouping column (OP's example plot has two errorbars per x value, saying the data is sourced from two files), then you should get all the data in one data frame at the start, add the grouping variable to the dplyr::group_by call (e.g., group_by(x, file) if file is the name of the column) and add it as a "group" aesthetic in the ggplot, e.g., aes(x = x, y = ymean, group = file).

I know I'm a bit late for that one, but I'll share what I did too, in case it helps someone else :

HashMap<String, HashMap> selects = new HashMap<String, HashMap>();

for(Map.Entry<String, HashMap> entry : selects.entrySet()) {
    String key = entry.getKey();
    HashMap value = entry.getValue();

    // do what you have to do here
    // In your case, another loop.
}

Good question.

• @@IDENTITY: returns the last identity value generated on your SQL connection (SPID). Most of the time it will be what you want, but sometimes it isn't (like when a trigger is fired in response to an INSERT, and the trigger executes another INSERT statement).

• SCOPE_IDENTITY(): returns the last identity value generated in the current scope (i.e. stored procedure, trigger, function, etc).

• IDENT_CURRENT(): returns the last identity value for a specific table. Don't use this to get the identity value from an INSERT, it's subject to race conditions (i.e. multiple connections inserting rows on the same table).

• IDENTITY(): used when declaring a column in a table as an identity column.

For more reference, see: http://msdn.microsoft.com/en-us/library/ms187342.aspx.

To summarize: if you are inserting rows, and you want to know the value of the identity column for the row you just inserted, always use SCOPE_IDENTITY().

I know this may be a bit old, but try using PDO::lastInsertId. I think it does what you want it to, but you would have to rewrite your application to use PDO (Which is a lot safer against attacks)

For me the following worked:

(1) First fetch all changes:

$ git fetch --all

(2) Then reset the master:

$ git reset --hard origin/master

(3) Pull/update:

$ git pull

A semaphore is a way to lock a resource so that it is guaranteed that while a piece of code is executed, only this piece of code has access to that resource. This keeps two threads from concurrently accesing a resource, which can cause problems.

no one says that you also have to have mod_headers enabled, so if still not working, try this:

(following tips works on Ubuntu, don't know about other distributions)

you can check list of loaded modules with

apache2ctl -M

to enable mod_headers you can use

a2enmod headers

of course after any changes in Apache you have to restart it:

/etc/init.d/apache2 restart

Then you can use

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

And if mod_headers is not active, this line will do nothing at all. You can try skip if clause and just add Header set Access-Control-Allow-Origin "*" in your config, then it should throw error during start if mod_headers is not active.

I think there is an easier way

import pandas as pd

dataset = pd.read_csv('table1.csv')
ftCol = dataset.iloc[:, 0].values

So in here iloc[:, 0], : means all values, 0 means the position of the column. in the example below ID will be selected

ID | Name | Address | City | State | Zip | Phone | OPEID | IPEDS |
10 | C... | 130 W.. | Mo.. | AL... | 3.. | 334.. | 01023 | 10063 |

Upgrade your test project to the latest target framework version.

I was using Visual studio 2019 with target framework 4.5 whose support ended in 2016, jumping to 4.7 solved my problem.

it seems that you should set your command as an String[],for example:

String[] command = new String[]{"rmiregistry","2020"};
Runtime.getRuntime().exec(command);

it just like the style of main(String[] args).

Use android.util.Log and the static methods defined there (e.g., e(), w()).

Does your dump contain features that are not supported in your version of MySQL? You can also try to remove the starting (and ending) MySQL commented SET-statements.

I don't know if your dump comes from a Linux version of MySQL (line endings)?

There are some kind of misunderstanding about lazy collections in JPA-Hibernate. First of all let's clear that why trying to read a lazy collection throws exceptions and not just simply returns NULL for converting or further use cases?.

That's because Null fields in Databases especially in joined columns have meaning and not simply not-presented state, like programming languages. when you're trying to interpret a lazy collection to Null value it means (on Datastore-side) there is no relations between these entities and it's not true. so throwing exception is some kind of best-practice and you have to deal with that not the Hibernate.

So as mentioned above I recommend to :

1. Detach the desired object before modifying it or using stateless session for querying
2. Manipulate lazy fields to desired values (zero,null,etc.)

also as described in other answers there are plenty of approaches(eager fetch, joining etc.) or libraries and methods for doing that, but you have to setting up your view of what's happening before dealing with the problem and solving it.

To use the hex encoding in Python 3, use

>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'

In legacy Python, there are several other ways of doing this:

>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'

Don't know if it will help, but you can try simulating a submit button click, instead of directly submitting the form. I have the following code in production, and it works fine:

    $('.input').keypress(function(e) {
        if(e.which == 13) {
            jQuery(this).blur();
            jQuery('#submit').focus().click();
        }
    });

Note: jQuery('#submit').focus() makes the button animate when enter is pressed.

The short answer here is the serial ID is computed via a hash if you don't specify it. (Static members are not inherited--they are static, there's only (1) and it belongs to the class).

http://docs.oracle.com/javase/6/docs/platform/serialization/spec/class.html

The getSerialVersionUID method returns the serialVersionUID of this class. Refer to Section 4.6, "Stream Unique Identifiers." If not specified by the class, the value returned is a hash computed from the class's name, interfaces, methods, and fields using the Secure Hash Algorithm (SHA) as defined by the National Institute of Standards.

If you alter a class or its hierarchy your hash will be different. This is a good thing. Your objects are different now that they have different members. As such, if you read it back in from its serialized form it is in fact a different object--thus the exception.

The long answer is the serialization is extremely useful, but probably shouldn't be used for persistence unless there's no other way to do it. Its a dangerous path specifically because of what you're experiencing. You should consider a database, XML, a file format and probably a JPA or other persistence structure for a pure Java project.

All the other answers use variables and SET operations. Here's a way to do it within a select statement. Just drop this in as a column in your existing select.

    (SELECT 
        '<table style=''font-family:"Verdana"; font-size: 10pt''>'
                    + '<tr bgcolor="#9DBED4"><th>col1</th><th>col2</th><th>col3</th><th>col4</th><th>col5</th></tr>'
                    + replace( replace( body, '&lt;', '<' ), '&gt;', '>' )
                    + '</table>'
    FROM
    (
        select cast( (
            select td = cast(col1 as varchar(5)) + '</td><td align="right">' + col2 + '</td><td>' + col3 + '</td><td align="right">' + cast(col4 as varchar(5)) + '</td><td align="right">' + cast(col5 as varchar(5)) + '</td>'
            from (
                    select col1  = col1,
                            col2 = col2,
                            col3 = col3,
                            col4 = col4,
                            col5 = col5
                    from m_LineLevel as onml
                    where onml.pkey = oni.pkey
                    ) as d
            for xml path( 'tr' ), type ) as varchar(max) ) as body
    ) as bodycte) as LineTable

Some conventions list all the public methods first, and then all the private ones - that means it's easy to separate the API from the implementation, even when there's no interface involved, if you see what I mean.

Another idea is to group related methods together - this makes it easier to spot seams where you could split your existing large class into several smaller, more targeted ones.

There is just a caveat that I discovered today. If you have a function that is calling a plot a lot of times you better use plt.close(fig) instead of fig.clf() somehow the first does not accumulate in memory. In short if memory is a concern use plt.close(fig) (Although it seems that there are better ways, go to the end of this comment for relevant links).

So the the following script will produce an empty list:

for i in range(5):
    fig = plot_figure()
    plt.close(fig)
# This returns a list with all figure numbers available
print(plt.get_fignums())

Whereas this one will produce a list with five figures on it.

for i in range(5):
    fig = plot_figure()
    fig.clf()
# This returns a list with all figure numbers available
print(plt.get_fignums())

From the documentation above is not clear to me what is the difference between closing a figure and closing a window. Maybe that will clarify.

If you want to try a complete script there you have:

import numpy as np
import matplotlib.pyplot as plt
x = np.arange(1000)
y = np.sin(x)

for i in range(5):
    fig = plt.figure()
    ax = fig.add_subplot(1, 1, 1)
    ax.plot(x, y)
    plt.close(fig)

print(plt.get_fignums())

for i in range(5):
    fig = plt.figure()
    ax = fig.add_subplot(1, 1, 1)
    ax.plot(x, y)
    fig.clf()

print(plt.get_fignums())

If memory is a concern somebody already posted a work-around in SO see: Create a figure that is reference counted

You don't have to always use a weak reference. If your block is not retained, but executed and then discarded, you can capture self strongly, as it will not create a retain cycle. In some cases, you even want the block to hold the self until the completion of the block so it does not deallocate prematurely. If, however, you capture the block strongly, and inside capture self, it will create a retain cycle.

Here is the example in which you can easily find the way to use Post,GET method and use the same way to add other curd operations as well..

        limit_url = request.args.get('limit', default=20, type=int)
        questions = mongo.db.questions.find().limit(limit_url).skip(start);

To use arrow functions with function.prototype.call, I made a helper function on the object prototype:

  // Using
  // @func = function() {use this here} or This => {use This here}
  using(func) {
    return func.call(this, this);
  }

usage

  var obj = {f:3, a:2}
  .using(This => This.f + This.a) // 5

Edit

You don't NEED a helper. You could do:

var obj = {f:3, a:2}
(This => This.f + This.a).call(undefined, obj); // 5

On Scientific Linux 6 (similar to CentOS 6-- SL is now replaced by CentOS, AIUI), I had to use /usr/sbin/prelink -av -mR which I found suggested at https://stelfox.net/blog/2014/08/dependency-prelink-issues/

Until I did that, I got a cc1 error gcc: error trying to exec 'cc1': execvp: No such file or directory when I tried to compile, and gcc --version reported 4.2.2 instead of 4.4.7, despite that version being reported by yum.

Your new class:

public class TimeWatch {    
    long starts;

    public static TimeWatch start() {
        return new TimeWatch();
    }

    private TimeWatch() {
        reset();
    }

    public TimeWatch reset() {
        starts = System.currentTimeMillis();
        return this;
    }

    public long time() {
        long ends = System.currentTimeMillis();
        return ends - starts;
    }

    public long time(TimeUnit unit) {
        return unit.convert(time(), TimeUnit.MILLISECONDS);
    }
}

Usage:

    TimeWatch watch = TimeWatch.start();
    // do something
    long passedTimeInMs = watch.time();
    long passedTimeInSeconds = watch.time(TimeUnit.SECONDS);

Afterwards, the time passed can be converted to whatever format you like, with a calender for example

Spring MVC will give you the HttpRequest if you just add it to your controller method signature:

For instance:

/**
 * Generate a PDF report...
 */
@RequestMapping(value = "/report/{objectId}", method = RequestMethod.GET)
public @ResponseBody void generateReport(
        @PathVariable("objectId") Long objectId, 
        HttpServletRequest request, 
        HttpServletResponse response) {

    // ...
    // Here you can use the request and response objects like:
    // response.setContentType("application/pdf");
    // response.getOutputStream().write(...);

}

As you see, simply adding the HttpServletRequest and HttpServletResponse objects to the signature makes Spring MVC to pass those objects to your controller method. You'll want the HttpSession object too.

EDIT: It seems that HttpServletRequest/Response are not working for some people under Spring 3. Try using Spring WebRequest/WebResponse objects as Eduardo Zola pointed out.

I strongly recommend you to have a look at the list of supported arguments that Spring MVC is able to auto-magically inject to your handler methods.

Do the build job on Jenkins first without Sonar configured. Then add Sonar, and run a build job again. Should fix the problem

Use:

git log --graph --abbrev-commit --decorate  --first-parent <branch_name>

It is only for the target branch (of course --graph, --abbrev-commit --decorate are more polishing).

The key option is --first-parent: "Follow only the first parent commit upon seeing a merge commit" (https://git-scm.com/docs/git-log)

It prevents the commit forks from being displayed.

Agree with neubert about the DECLARE statements, this will fix syntax error. But I would suggest you to avoid using openning cursors, they may be slow.

See the 9 line of your code,it may be an error; it should be:

mail.smtp.user 

not

mail.stmp.user;

It sounds like the admin has locked the "authentication" node of the web.config, which one can do in the global web.config pretty easily. Or, in a nutshell, this is working as designed.

I wrote this one:

Function sheetExist(sSheet As String) As Boolean
On Error Resume Next
sheetExist = (ActiveWorkbook.Sheets(sSheet).Index > 0)
End Function

Go to the XML layout Text where the widget (button or other View) indicates error, focus the cursor there and press alt+enter and select missing constraints attributes.

The simplest way is to use: Request::url();

But here is a complex way:

URL::to('/').'/'.Route::getCurrentRoute()->getPath();

For powers of 2:

var twoToThePowerOf = 1 << yourExponent;
// eg: 1 << 12 == 4096

You can use DataTable.Select:

var strExpr = "CostumerID = 1 AND OrderCount > 2";
var strSort = "OrderCount DESC";

// Use the Select method to find all rows matching the filter.
foundRows = ds.Table[0].Select(strExpr, strSort);  

Or you can use DataView:

ds.Tables[0].DefaultView.RowFilter = strExpr;  

UPDATE I'm not sure why you want to have a DataSet returned. But I'd go with the following solution:

var dv = ds.Tables[0].DefaultView;
dv.RowFilter = strExpr;
var newDS = new DataSet();
var newDT = dv.ToTable();
newDS.Tables.Add(newDT);
