Hoping to provide a more nuanced answer than any of the ones here, especially as some things have changed since this was originally asked ~4 years ago, and because many of the top-voted answers claiming that you have to set this up as two separate applications are not accurate.

You have two primary architecture options:

1. A completely decoupled client/server approach using something like create-react-app and Django REST Framework
2. A hybrid architecture where you set up a React build pipeline (likely using webpack) and then include the compiled files as static files in your Django templates.

These might look something like this:

Option 1 (Client/Server Architecture):

Option 2 (Hybrid Architecture):

The decision between these two will depend on your / your team's experience, as well as the complexity of your UI. The first option is good if you have a lot of JS experience, want to keep your front-end / back-end developers separate, or want to write your entire application as a React single-page-app. The second option is generally better if you are more familiar with Django and want to move quickly while also using React for some parts of your app. I find it's a particularly good fit for full-stack solo-developers.

There is a lot more information in the series "Modern JavaScript for Django Developers", including choosing your architecture, integrating your JS build into a Django project and building a single-page React app.

Full disclosure, I'm the author of that series.

I have a working codepen with left- and right-aligned nav links that all collapse into a responsive menu together using .justify-content-between on the parent tag: https://codepen.io/epan/pen/bREVVW?editors=1000

<nav class="navbar navbar-toggleable-sm navbar-inverse bg-inverse">
  <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbar"     aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <a class="navbar-brand" href="#">Acme</a>
  <div class="collapse navbar-collapse justify-content-between" id="navbar">
    <div class="navbar-nav">
      <a class="nav-item nav-link" href="#">Ball Bearings</a>
      <a class="nav-item nav-link" href="#">TNT Boxes</a>
    </div>
    <div class="navbar-nav">
      <a class="nav-item nav-link" href="#">Logout</a>
    </div>
  </div>
</nav>

That's correct, your response is an object with fields:

{
    "page": 1,
    "results": [ ... ]
}

So you in fact want to iterate the results field only:

this.data = res.json()['results'];

... or even easier:

this.data = res.json().results;

After years of using XAMPP finally I've given up, and started looking for alternatives. XAMPP has not received any updates for quite a while and it kept breaking down once every two weeks.

The one I've just found and I could absolutely recommend is The Uniform Server

It's really frequently updated, has much more emphasis on security and looks like a much more mature project compared to XAMPP.

They have a wiki where they list all the latest versions of packages. As the time of writing, their newest release is only 4 days old!

Versions in Uniform Server as of today:

• Apache 2.4.2
• MySQL 5.5.23-community
• PHP 5.4.1
• phpMyAdmin 3.5.0

Versions in XAMPP as of today:

• Apache 2.2.21
• MySQL 5.5.16
• PHP 5.3.8
• phpMyAdmin 3.4.5

Most likely your query failed, and the query call returned a boolean FALSE (or an error object of some sort), which you then try to use as if was a resultset object, causing the error. Try something like var_dump($result) to see what you really got.

Check for errors after EVERY database query call. Even if the query itself is syntactically valid, there's far too many reasons for it to fail anyways - checking for errors every time will save you a lot of grief at some point.

NoSQL is better than RDBMS because of the following reasons/properities of NoSQL

1. It supports semi-structured data and volatile data
2. It does not have schema
3. Read/Write throughput is very high
4. Horizontal scalability can be achieved easily
5. Will support Bigdata in volumes of Terra Bytes & Peta Bytes
6. Provides good support for Analytic tools on top of Bigdata
7. Can be hosted in cheaper hardware machines
8. In-memory caching option is available to increase the performance of queries
9. Faster development life cycles for developers

EDIT:

To answer "why RDBMS cannot scale", please take a look at RDBMS Overheads pdf written by Stavros Harizopoulos,Daniel J. Abadi,Samuel Madden and Michael Stonebraker

RDBMS's have challenges in handling huge data volumes of Terabytes & Peta bytes. Even if you have Redundant Array of Independent/Inexpensive Disks (RAID) & data shredding, it does not scale well for huge volume of data. You require very expensive hardware.

Logging: Assembling log records and tracking down all changes in database structures slows performance. Logging may not be necessary if recoverability is not a requirement or if recoverability is provided through other means (e.g., other sites on the network).

Locking: Traditional two-phase locking poses a sizeable overhead since all accesses to database structures are governed by a separate entity, the Lock Manager.

Latching: In a multi-threaded database, many data structures have to be latched before they can be accessed. Removing this feature and going to a single-threaded approach has a noticeable performance impact.

Buffer management: A main memory database system does not need to access pages through a buffer pool, eliminating a level of indirection on every record access.

This does not mean that we have to use NoSQL over SQL.

Still, RDBMS is better than NoSQL for the following reasons/properties of RDBMS

1. Transactions with ACID properties - Atomicity, Consistency, Isolation & Durability
2. Adherence to Strong Schema of data being written/read
3. Real time query management ( in case of data size < 10 Tera bytes )
4. Execution of complex queries involving join & group by clauses

We have to use RDBMS (SQL) and NoSQL (Not only SQL) depending on the business case & requirements

The reason why you're getting that error is because you've declared your struct as:

struct {
 char name[32];
 int  size;
 int  start;
 int  popularity;
} stasher_file;

This is not declaring a stasher_file type. This is declaring an anonymous struct type and is creating a global instance named stasher_file.

What you intended was:

struct stasher_file {
 char name[32];
 int  size;
 int  start;
 int  popularity;
};

But note that while Brian R. Bondy's response wasn't correct about your error message, he's right that you're trying to write into the struct without having allocated space for it. If you want an array of pointers to struct stasher_file structures, you'll need to call malloc to allocate space for each one:

struct stasher_file *newFile = malloc(sizeof *newFile);
if (newFile == NULL) {
   /* Failure handling goes here. */
}
strncpy(newFile->name, name, 32);
newFile->size = size;
...

(BTW, be careful when using strncpy; it's not guaranteed to NUL-terminate.)

Instead of the conventional read.table I feel fread is a faster function. Specifying additional attributes like select only the required columns, specifying colclasses and string as factors will reduce the time take to import the file.

data_frame <- fread("filename.csv",sep=",",header=FALSE,stringsAsFactors=FALSE,select=c(1,4,5,6,7),colClasses=c("as.numeric","as.character","as.numeric","as.Date","as.Factor"))

I used tel: for my project.

It worked in Chrome, Firefox, IE9&8, Chrome mobile and the mobile Browser on my Sony Ericsson smartphone.

But callto: did not work in the mobile Browsers.

Best way to get the status code using alamofire.

 Alamofire.request(URL).responseJSON {
  response in

  let status = response.response?.statusCode
  print("STATUS \(status)")

}

I have created simple demo class for your better reference.

FirstActivity.java

 public class FirstActivity extends AppCompatActivity {

    private static final String TAG = FirstActivity.class.getSimpleName();
    private static final int REQUEST_CODE = 101;
    private Button btnMoveToNextScreen;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnMoveToNextScreen = (Button) findViewById(R.id.btnMoveToNext);
        btnMoveToNextScreen.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent mIntent = new Intent(FirstActivity.this, SecondActivity.class);
                startActivityForResult(mIntent, REQUEST_CODE);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(resultCode == RESULT_OK){
            if(requestCode == REQUEST_CODE && data !=null) {
                String strMessage = data.getStringExtra("keyName");
                Log.i(TAG, "onActivityResult: message >>" + strMessage);
            }
        }

    }
}

And here is SecondActivity.java

public class SecondActivity extends AppCompatActivity {

    private static final String TAG = SecondActivity.class.getSimpleName();
    private Button btnMoveToPrevious;
    private EditText editText;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        editText = (EditText) findViewById(R.id.editText);

        btnMoveToPrevious = (Button) findViewById(R.id.btnMoveToPrevious);
        btnMoveToPrevious.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String message = editText.getEditableText().toString();

                Intent mIntent = new Intent();
                mIntent.putExtra("keyName", message);
                setResult(RESULT_OK, mIntent);
                finish();

            }
        });

    }
}

Here is a great explaination on this!

You could do like this:

SELECT city FROM user WHERE (firstName, lastName) IN (('a', 'b'), ('c', 'd'));

The sqlfiddle.

I was looking for shortest way to draw an 1px line, as whole load of separated CSS is not the fastest or shortest solution.

Up to HTML5, the WAS a shorter way for 1px hr: <hr noshade> but.. The noshade attribute of <hr> is not supported in HTML5. Use CSS instead. (nor other attibutes used before, as size, width, align)...

Now, this one is quite tricky, but works well if most simple 1px hr needed:

Variation 1, BLACK hr: (best solution for black)

<hr style="border-bottom: 0px">

Output: FF, Opera - black / Safari - dark gray

Variation 2, GRAY hr (shortest!):

<hr style="border-top: 0px">

Output: Opera - dark gray / FF - gray / Safari - light gray

<hr style="border: none; border-bottom: 1px solid red;">

Output: Opera / FF / Safari : 1px red.

In PHP there is a pretty good function utf8_encode() to solve this issue.

echo utf8_encode("Résumé");

//will output Résumé instead of R?sum?

Check the official PHP page.

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

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

strftime() doesn't officially support %z.

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

Guzzle implements PSR-7. That means that it will by default store the body of a message in a Stream that uses PHP temp streams. To retrieve all the data, you can use casting operator:

$contents = (string) $response->getBody();

You can also do it with

$contents = $response->getBody()->getContents();

The difference between the two approaches is that getContents returns the remaining contents, so that a second call returns nothing unless you seek the position of the stream with rewind or seek .

$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents

Instead, usings PHP's string casting operations, it will reads all the data from the stream from the beginning until the end is reached.

$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents

Documentation: http://docs.guzzlephp.org/en/latest/psr7.html#responses

It largely depends on the library you decide to use. For instance, if you use the wxWidgets library, the creation of a thread would look like this:

class RThread : public wxThread {

public:
    RThread()
        : wxThread(wxTHREAD_JOINABLE){
    }
private:
    RThread(const RThread &copy);

public:
    void *Entry(void){
        //Do...

        return 0;
    }

};

wxThread *CreateThread() {
    //Create thread
    wxThread *_hThread = new RThread();

    //Start thread
    _hThread->Create();
    _hThread->Run();

    return _hThread;
}

If your main thread calls the CreateThread method, you'll create a new thread that will start executing the code in your "Entry" method. You'll have to keep a reference to the thread in most cases to join or stop it. More info here: wxThread documentation

You can use the Codecs module in the Python Standard Library, i.e.

import codecs

codecs.decode(hexstring, 'hex_codec')

Well i found a bit faster and easier version to use

shell_exec('screen -dmS $name_of_screen $command'); 

and it works.

Use alter session set current_schema = <username>, in your case as an execute immediate.

See Oracle's documentation for further information.

In your case, that would probably boil down to (untested)

DECLARE

   CURSOR client_cur IS
     SELECT  distinct username 
       from all_users 
      where length(username) = 3;

   -- client cursor 
   CURSOR emails_cur IS
   SELECT id, name 
     FROM org;

BEGIN

   FOR client IN client_cur LOOP

   -- ****
      execute immediate 
     'alter session set current_schema = ' || client.username;
   -- ****

      FOR email_rec in client_cur LOOP

         dbms_output.put_line(
             'Org id is ' || email_rec.id || 
             ' org nam '  || email_rec.name);

      END LOOP;

  END LOOP;
END;
/

The below is a working example. Add async:false.

const response = $.ajax({
                    type:"POST",
                    dataType:"json",
                    async:false, 
                    url:"your-url",
                    data:{"data":"data"}                        
                });                   
 console.log("response: ", response);

Try to use IF(condition, value1, value2)

SELECT ID, HEADING, 
IF(action_type='Income',action_amount,0) as Income,
IF(action_type='Expense',action_amount,0) as Expense

I'm surprised there's been no mention of filter_var here for this being such an old question...

PHP has a built in method of doing this using sanitization filters. Specifically, the one to use in this situation is FILTER_SANITIZE_NUMBER_FLOAT with the FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND flags. Like so:

$numeric_filtered = filter_var("AR3,373.31", FILTER_SANITIZE_NUMBER_FLOAT,
    FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND);
echo $numeric_filtered; // Will print "3,373.31"

It might also be worthwhile to note that because it's built-in to PHP, it's slightly faster than using regex with PHP's current libraries (albeit literally in nanoseconds).

You can definetely build your code from Vim, that's what the :make command does.

However, you need to go through the basics first : type vimtutor in your terminal and follow the instructions to the end.

After you have completed it a few times, open an existing (non-important) text file and try out all the things you learned from vimtutor: entering/leaving insert mode, undoing changes, quitting/saving, yanking/putting, moving and so on.

For a while you won't be productive at all with Vim and will probably be tempted to go back to your previous IDE/editor. Do that, but keep up with Vim a little bit every day. You'll probably be stopped by very weird and unexpected things but it will happen less and less.

In a few months you'll find yourself hitting o, v and i all the time in every textfield everywhere.

Have fun!

The only way I able to get this to work was by doing this on the presenting view controller:

    func didTapButton() {
    self.definesPresentationContext = true
    self.modalTransitionStyle = .crossDissolve
    let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "YourViewController") as! YourViewController
    let navController = UINavigationController(rootViewController: yourVC)
    navController.modalPresentationStyle = .overCurrentContext
    navController.modalTransitionStyle = .crossDissolve
    self.present(navController, animated: true, completion: nil)
}

Branches in SVN are essentially directories; you don't name the branch so much as choose the name of the directory to branch into.

The common way of 'naming' a branch is to place it under a directory called branches in your repository. In the "To URL:" portion of TortoiseSVN's Branch dialog, you would therefore enter something like:

(svn/http)://path-to-repo/branches/your-branch-name

The main branch of a project is referred to as the trunk, and is usually located in:

(svn/http)://path-to-repo/trunk

It happens when $ret hasn't been defined. The solution is simple. Right above $tags = get_tags();, add the following line:

$ret = array();

As another option and for posterity I was looking into this recently and found a solution that allows a much shorter loop by handing some of the work off to the System class, which (if the JVM you're using is smart enough) can be turned into a memset operation:-

/*
 * initialize a smaller piece of the array and use the System.arraycopy 
 * call to fill in the rest of the array in an expanding binary fashion
 */
public static void bytefill(byte[] array, byte value) {
  int len = array.length;

  if (len > 0){
    array[0] = value;
  }

  //Value of i will be [1, 2, 4, 8, 16, 32, ..., len]
  for (int i = 1; i < len; i += i) {
    System.arraycopy(array, 0, array, i, ((len - i) < i) ? (len - i) : i);
  }
}

This solution was taken from the IBM research paper "Java server performance: A case study of building efficient, scalable Jvms" by R. Dimpsey, R. Arora, K. Kuiper.

Simplified explanation

As the comment suggests, this sets index 0 of the destination array to your value then uses the System class to copy one object i.e. the object at index 0 to index 1 then those two objects (index 0 and 1) into 2 and 3, then those four objects (0,1,2 and 3) into 4,5,6 and 7 and so on...

Efficiency (at the point of writing)

In a quick run through, grabbing the System.nanoTime() before and after and calculating a duration I came up with:-

• This method : 332,617 - 390,262 ('highest - lowest' from 10 tests)
• Float[] n = new Float[array.length]; //Fill with null : 666,650
• Setting via loop : 3,743,488 - 9,767,744 ('highest - lowest' from 10 tests)
• Arrays.fill : 12,539,336

The JVM and JIT compilation

It should be noted that as the JVM and JIT evolves, this approach may well become obsolete as library and runtime optimisations could reach or even exceed these numbers simply using fill(). At the time of writing, this was the fastest option I had found. It has been mentioned this might not be the case now but I have not checked. This is the beauty and the curse of Java.

There is a pseudocolumn called %%physloc%% that shows the physical address of the row.

The more canonical reference is in <HIToolbox/Events.h>:

localhost works now. However, remember that after adding localhost to list of domain names, it takes up to 30 minutes to take effect (according to the help tip shown against the domain names list).

You can hide the modal and popup the window to review the carts in validateShipping() function itself.

function validateShipping(){
...
...
$('#product-options').modal('hide');
//pop the window to select items
}

Eazy

// Create list
var myList = new List<string>();

// Add items to the list
myList.Add("item1");
myList.Add("item2");

// Convert to array
var myArray = myList.ToArray();

Although all other answers are technically correct, I would recommend you adding the custom path to the beginning of your PATH, not at the end. That way it would be the first place to look for instead of the last:

Add to bottom of ~/.bash_profile:

export PATH="/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/":$PATH

That way if you have more than one java or javac it will use the one you provided first.

What you can try is writing your code as normal for python using the normal input command. However the trick is to add at the beginning of you program the command input=raw_input.

Now all you have to do is disable (or enable) depending on if you're running in Python/IDLE or Terminal. You do this by simply adding '#' when needed.

Switched off for use in Python/IDLE

    #input=raw_input 

And of course switched on for use in terminal.

    input=raw_input 

I'm not sure if it will always work, but its a possible solution for simple programs or scripts.

Have you tried copying the schema file to the XML Schema Caching folder for VS? You can find the location of that folder by looking at VS Tools/Options/Test Editor/XML/Miscellaneous. Unfortunately, i don't know where's the schema file for the MS Enterprise Library 4.0.

Update: After installing MS Enterprise Library, it seems there's no .xsd file. However, there's a tool for editing the configuration - EntLibConfig.exe, which you can use to edit the configuration files. Also, if you add the proper config sections to your config file, VS should be able to parse the config file properly. (EntLibConfig will add these for you, or you can add them yourself). Here's an example for the loggingConfiguration section:

<configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>

You also need to add a reference to the appropriate assembly in your project.

shortcut method to list out all commands. Open terminal and press two times "tab" button. Thats show all commands in terminal

For comparison between two times use time.Sub()

// utc life
loc, _ := time.LoadLocation("UTC")

// setup a start and end time
createdAt := time.Now().In(loc).Add(1 * time.Hour)
expiresAt := time.Now().In(loc).Add(4 * time.Hour)

// get the diff
diff := expiresAt.Sub(createdAt)
fmt.Printf("Lifespan is %+v", diff)

The program outputs:

Lifespan is 3h0m0s

You cannot set focus to a control if it has not been rendered. Form.Load() occurs before the controls are rendered.

Go to the form's events and double click the "Shown" event. In the form's shown event handler call the control.Focus() method.

    private void myForm_Shown(object sender, EventArgs e)
    {
        // Call textbox's focus method
        txtMyTextbox.Focus();
    }

The following worked the best for me, basically I'm scrapping any existing tooltip and not bothering to show the new tooltip. If calling show on the tooltip like in other answers, it pops up even if the cursor isn't hovering above it.

The reason I went for this solution is that the other solutions, re-using the existing tooltip, led to some strange issues with the tooltip sometimes not showing when hovering the cursor above the element.

function updateTooltip(element, tooltip) {
    if (element.data('tooltip') != null) {
        element.tooltip('hide');
        element.removeData('tooltip');
    }
    element.tooltip({
        title: tooltip
    });
}

During ssh session my connection broke, since then I cannot ssh my SRV, I had started a new instance, and I'm able to ssh the new instance (with the same key).

I mounted the old volume to the new machine, and check the .ssh/authorized_key and couldn't find any problem with permission or content.

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

At original time of writing to uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

string[] tokens = str.Split(new[] { "is Marco and" }, StringSplitOptions.None);

If you have a single character delimiter (like for instance ,), you can reduce that to (note the single quotes):

string[] tokens = str.Split(',');

In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:

<script type="javascript">
    day = new Array(<?php echo implode(',', $day); ?>);
    week = new Array(<?php echo implode(',',$week); ?>);
    month = new Array(<?php echo implode(',',$month); ?>);

    <!--  Then pass it to the JavaScript function:   -->

    drawChart(<?php echo count($day); ?>, day, week, month);
</script>

computed: {
  fullName: (app)=> (salut)=> {
      return salut + ' ' + this.firstName + ' ' + this.lastName    
  }
}

when you want use

<p>{{fullName('your salut')}}</p>

Why not simply return your calculated value and let the caller modify the global variable. It's not a good idea to manipulate a global variable within a function, as below:

Var1 = 1
Var2 = 0

def function(): 
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    return Var1 - 1

Var1 = function()

or even make local copies of the global variables and work with them and return the results which the caller can then assign appropriately

def function():
v1, v2 = Var1, Var2
# calculate using the local variables v1 & v2
return v1 - 1

Var1 = function()

You can try to do my answer,

you wrote this:

<?php
foreach($group_membership as $i => $username) {
    $items = array($username);
}

print_r($items);
?>

And in your case I would do this:

<?php
$items = array();
foreach ($group_membership as $username) { // If you need the pointer (but I don't think) you have to add '$i => ' before $username
    $items[] = $username;
} ?>

As you show in your question it seems that you need an array of usernames that are in a particular group :) In this case I prefer a good sql query with a simple while loop ;)

<?php
$query = "SELECT `username` FROM group_membership AS gm LEFT JOIN users AS u ON gm.`idUser` = u.`idUser`";
$result = mysql_query($query);
while ($record = mysql_fetch_array($result)) { \
    $items[] = $username; 
} 
?>

while is faster, but the last example is only a result of an observation. :)

Thanks Anda, your post has been a great help!! However the OR sentence didnt' quite work for me and I was getting an error: getCollection() "invalid argument supplied for foreach".

So this is what I ended with (notice the attribute being specified 3 times instead of 2 in this case):

  $collection->addFieldToFilter('attribute', array(  
    array('attribute'=>'my_field1','eq'=>'my_value1'),            
    array('attribute'=>'my_field2','eq'=>'my_value2') ));

addFieldToFilter first requires a field and then condition -> link.

i strongly suggest ditto. just works.

1. Initialization of base class

One important reason for using constructor initializer list which is not mentioned in answers here is initialization of base class.

As per the order of construction, base class should be constructed before child class. Without constructor initializer list, this is possible if your base class has default constructor which will be called just before entering the constructor of child class.

But, if your base class has only parameterized constructor, then you must use constructor initializer list to ensure that your base class is initialized before child class.

2. Initialization of Subobjects which only have parameterized constructors

3. Efficiency

Using constructor initializer list, you initialize your data members to exact state which you need in your code rather than first initializing them to their default state & then changing their state to the one you need in your code.

4. Initializing non-static const data members

If non-static const data members in your class have default constructors & you don't use constructor initializer list, you won't be able to initialize them to intended state as they will be initialized to their default state.

5. Initialization of reference data members

Reference data members must be intialized when compiler enters constructor as references can't be just declared & initialized later. This is possible only with constructor initializer list.

OK, so thanks to all of the contributors above. I am using .NET 4.6 and we also had the same issue. I spent time debugging System.Net.Http, specifically the HttpClientHandler, and found the following:

    if (ExecutionContext.IsFlowSuppressed())
    {
      IWebProxy webProxy = (IWebProxy) null;
      if (this.useProxy)
        webProxy = this.proxy ?? WebRequest.DefaultWebProxy;
      if (this.UseDefaultCredentials || this.Credentials != null || webProxy != null && webProxy.Credentials != null)
        this.SafeCaptureIdenity(state);
    }

So after assessing that the ExecutionContext.IsFlowSuppressed() might have been the culprit, I wrapped our Impersonation code as follows:

using (((WindowsIdentity)ExecutionContext.Current.Identity).Impersonate())
using (System.Threading.ExecutionContext.SuppressFlow())
{
    // HttpClient code goes here!
}

The code inside of SafeCaptureIdenity (not my spelling mistake), grabs WindowsIdentity.Current() which is our impersonated identity. This is being picked up because we are now suppressing flow. Because of the using/dispose this is reset after invocation.

It now seems to work for us, phew!

PYTHONPATH ends up in sys.path, which you can modify at runtime.

import sys
sys.path += ["whatever"]

You can try this

find . -type d -name .git -exec sh -c "cd \"{}\"/../ && pwd && git pull" \;

Also, you can add your customized output by adding one more && argument like.

find . -type d -name .git -exec sh -c "cd \"{}\"/../ && pwd && git pull && git status" \;

Here's my script that runs as LocalSystem on a machine, but needs credentials of a domaim user to access a network file location. It allows you to store the user's password in a "safe-ish" encrypted file; that can only be read by the user that wrote it.

Setting and changing the password is done by copying a file with the plaintext password in it to the machine. When the script is next run it reads the password, encrypts it, then deletes the plaintext password.

$plaintext_password_file = 'C:\plaintext.txt' # Stores the password in plain text - only used once, then deleted
$encryted_password_file = 'C:\copy_pass.txt'  # Stores the password in "safe" encrypted form - used for subsequent runs of the script
                                              #   - can only be decrypted by the windows user that wrote it
$file_copy_user = 'OURDOMAIN\A_User'

# Check to see if there is a new plaintext password
if (Test-Path $plaintext_password_file)
{
    # Read in plaintext password, convert to a secure-string, convert to an encrypted-string, and write out, for use later
    get-content $plaintext_password_file | convertto-securestring -asplaintext -force | convertfrom-securestring | out-file $encryted_password_file
    # Now we have encrypted password, remove plain text for safety
    Remove-Item $plaintext_password_file
}


# Read in the encrypted password, convert to a secure-string
$pass = get-content $encryted_password_file | convertto-securestring

# create a credential object for the other user, using username and password stored in secure-string
$credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist $file_copy_user,$pass

# Connect to network file location as the other user and map to drive J:
New-PSDrive -Name J -PSProvider FileSystem -Root "\\network\file_directory" -Credential $credentials

# Copy the file to J:
Copy-Item -Force -Verbose -Path "C:\a_file.txt" -Destination "J:\"

As an extra refinement: The username could also be encrypted as well, rather than hardcoded.

Change the order you're including your scripts (jQuery first):

<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript" src="./javascript.js"></script>
<script
    src="http://maps.googleapis.com/maps/api/js?key=YOUR_APIKEY&sensor=false">
</script>

Curent class .dropdown-submenu > .dropdown-menu have left: 100%;. So, if you want to open submenu on the left side, override those settings to negative left position. For example left: -95%;. Now you will get submenu on the left side, and you can tweak other settings to get perfect preview.

Here is DEMO

EDIT: OP's question and my answer are from august 2012. Meanwhile, Bootstrap changed, so now you have .pull-left class. Back then, my answer was correct. Now you don't have to manually set css, you have that .pull-left class.

EDIT 2: Demos aren't working, because Bootstrap changed their URL's. Just change external resources in jsfiddle and replace them with new ones.

If you only need to add one path per configuration (debug/release), you could set the debug command working directory:

Project | Properties | Select Configuration | Configuration Properties | Debugging | Working directory

Repeat for each project configuration.

1. What is the difference between Git and GitHub?

   Git is a distributed version control system. It usually runs at the command line of your local machine. It keeps track of your files and modifications to those files in a "repository" (or "repo"), but only when you tell it to do so. (In other words, you decide which files to track and when to take a "snapshot" of any modifications.)

   In contrast, GitHub is a website that allows you to publish your Git repositories online, which can be useful for many reasons (see #3).

2. Is Git saving every repository locally (in the user's machine) and in GitHub?

   Git is known as a "distributed" (rather than "centralized") version control system because you can run it locally and disconnected from the Internet, and then "push" your changes to a remote system (such as GitHub) whenever you like. Thus, repo changes only appear on GitHub when you manually tell Git to push those changes.

3. Can you use Git without GitHub? If yes, what would be the benefit for using GitHub?

   Yes, you can use Git without GitHub. Git is the "workhorse" program that actually tracks your changes, whereas GitHub is simply hosting your repositories (and provides additional functionality not available in Git). Here are some of the benefits of using GitHub:

   • It provides a backup of your files.
   • It gives you a visual interface for navigating your repos.
   • It gives other people a way to navigate your repos.
   • It makes repo collaboration easy (e.g., multiple people contributing to the same project).
   • It provides a lightweight issue tracking system.

4. How does Git compare to a backup system such as Time Machine?

   Git does backup your files, though it gives you much more granular control than a traditional backup system over what and when you backup. Specifically, you "commit" every time you want to take a snapshot of changes, and that commit includes both a description of your changes and the line-by-line details of those changes. This is optimal for source code because you can easily see the change history for any given file at a line-by-line level.

5. Is this a manual process, in other words if you don't commit you won't have a new version of the changes made?

   Yes, this is a manual process.

6. If are not collaborating and you are already using a backup system why would you use Git?

   • Git employs a powerful branching system that allows you to work on multiple, independent lines of development simultaneously and then merge those branches together as needed.
   • Git allows you to view the line-by-line differences between different versions of your files, which makes troubleshooting easier.
   • Git forces you to describe each of your commits, which makes it significantly easier to track down a specific previous version of a given file (and potentially revert to that previous version).
   • If you ever need help with your code, having it tracked by Git and hosted on GitHub makes it much easier for someone else to look at your code.

For getting started with Git, I recommend the online book Pro Git as well as GitRef as a handy reference guide. For getting started with GitHub, I like the GitHub's Bootcamp and their GitHub Guides. Finally, I created a short videos series to introduce Git and GitHub to beginners.

Here is a jQuery plugin that does exactly that: http://fixedheadertable.com/

Usage:

$('selector').fixedHeaderTable({ fixedColumn: 1 });

Set the fixedColumn option if you want any number of columns to be also fixed for horizontal scrolling.

EDIT: This example http://www.datatables.net/examples/basic_init/scroll_y.html is much better in my opinion, although with DataTables you'll need to get a better understanding of how it works in general.

EDIT2: For Bootstrap to work with DataTables you need to follow the instructions here: http://datatables.net/blog/Twitter_Bootstrap_2 (I have tested this and it works)- For Bootstrap 3 there's a discussion here: http://datatables.net/forums/discussion/comment/53462 - (I haven't tested this)

You can use literals, it's more compact.

NSString* myString = [@(17) stringValue];

(Boxes as a NSNumber and uses its stringValue method)

This should do it, removing characters from the left by one or however many needed.

lEFT(columnX,LEN(columnX) - 1) AS NewColumnName

You may want to use async/await, since node v10.0.0 it's possible with the built-in fs Promises API.

Example:

const fs = require('fs')

const copyFile = async (src, dest) => {
  await fs.promises.copyFile(src, dest)
}

Note:

As of node v11.14.0, v10.17.0 the API is no longer experimental.

More information:

Promises API

Promises copyFile

Java 9

public static void main(String[] args) {
    Map<Integer,String> map = Map.ofEntries(entry(1,"A"), entry(2,"B"), entry(3,"C"));
}

The jQuery answer was pretty useful to me. With a little refactory it fitted my needs well. I hope it helps anybody else.

function onReady ( callback ){
    var addListener = document.addEventListener || document.attachEvent,
        removeListener =  document.removeEventListener || document.detachEvent
        eventName = document.addEventListener ? "DOMContentLoaded" : "onreadystatechange"

    addListener.call(document, eventName, function(){
        removeListener( eventName, arguments.callee, false )
        callback()
    }, false )
}

This is a FAQ:

//someName[3]

means: all someName elements in the document, that are the third someName child of their parent -- there may be many such elements.

What you want is exactly the 3rd someName element:

(//someName)[3]

Explanation: the [] has a higher precedence (priority) than //. Remember always to put expressions of the type //someName in brackets when you need to specify the Nth node of their selected node-list.

$('#button').click(function(){
    $(this).addClass('active');
});

You can set the Field Separator:

... | awk 'BEGIN {FS="\t"}; {print $1}'

map rockets and add 10 to its launches:

var rockets = [_x000D_
    { country:'Russia', launches:32 },_x000D_
    { country:'US', launches:23 },_x000D_
    { country:'China', launches:16 },_x000D_
    { country:'Europe(ESA)', launches:7 },_x000D_
    { country:'India', launches:4 },_x000D_
    { country:'Japan', launches:3 }_x000D_
];_x000D_
rockets.map((itm) => {_x000D_
    itm.launches += 10_x000D_
    return itm_x000D_
})_x000D_
console.log(rockets)

If you don't want to modify rockets you can do:

var plusTen = []
rockets.forEach((itm) => {
    plusTen.push({'country': itm.country, 'launches': itm.launches + 10})
})

To understand this, you must take a step back. In OO, the customer owns the orders (orders are a list in the customer object). There can't be an order without a customer. So the customer seems to be the owner of the orders.

But in the SQL world, one item will actually contain a pointer to the other. Since there is 1 customer for N orders, each order contains a foreign key to the customer it belongs to. This is the "connection" and this means the order "owns" (or literally contains) the connection (information). This is exactly the opposite from the OO/model world.

This may help to understand:

public class Customer {
     // This field doesn't exist in the database
     // It is simulated with a SQL query
     // "OO speak": Customer owns the orders
     private List<Order> orders;
}

public class Order {
     // This field actually exists in the DB
     // In a purely OO model, we could omit it
     // "DB speak": Order contains a foreign key to customer
     private Customer customer;
}

The inverse side is the OO "owner" of the object, in this case the customer. The customer has no columns in the table to store the orders, so you must tell it where in the order table it can save this data (which happens via mappedBy).

Another common example are trees with nodes which can be both parents and children. In this case, the two fields are used in one class:

public class Node {
    // Again, this is managed by Hibernate.
    // There is no matching column in the database.
    @OneToMany(cascade = CascadeType.ALL) // mappedBy is only necessary when there are two fields with the type "Node"
    private List<Node> children;

    // This field exists in the database.
    // For the OO model, it's not really necessary and in fact
    // some XML implementations omit it to save memory.
    // Of course, that limits your options to navigate the tree.
    @ManyToOne
    private Node parent;
}

This explains for the "foreign key" many-to-one design works. There is a second approach which uses another table to maintain the relations. That means, for our first example, you have three tables: The one with customers, the one with orders and a two-column table with pairs of primary keys (customerPK, orderPK).

This approach is more flexible than the one above (it can easily handle one-to-one, many-to-one, one-to-many and even many-to-many). The price is that

• it's a bit slower (having to maintain another table and joins uses three tables instead of just two),
• the join syntax is more complex (which can be tedious if you have to manually write many queries, for example when you try to debug something)
• it's more error prone because you can suddenly get too many or too few results when something goes wrong in the code which manages the connection table.

That's why I rarely recommend this approach.

The third row you expect (the one with Powerpoint) is filtered out by the Computer.ID = 1 condition (try running the query with the Computer.ID = 1 or Computer.ID is null it to see what happens).

However, dropping that condition would not make sense, because after all, we want the list for a given Computer.

The only solution I see is performing a UNION between your original query and a new query that retrieves the list of application that are not found on that Computer.

The query might look like this:

DECLARE @ComputerId int
SET @ComputerId = 1

-- your original query
SELECT Computer.ComputerName, Application.Name, Software.Version
    FROM Computer
    JOIN dbo.Software_Computer
        ON Computer.ID = Software_Computer.ComputerID
    JOIN dbo.Software
        ON Software_Computer.SoftwareID = Software.ID
    RIGHT JOIN dbo.Application
        ON Application.ID = Software.ApplicationID
    WHERE Computer.ID = @ComputerId

UNION

-- query that retrieves the applications not installed on the given computer
SELECT Computer.ComputerName, Application.Name, NULL as Version
FROM Computer, Application
WHERE Application.ID not in 
    (
        SELECT s.ApplicationId
        FROM Software_Computer sc
        LEFT JOIN Software s on s.ID = sc.SoftwareId
        WHERE sc.ComputerId = @ComputerId
    )
AND Computer.id = @ComputerId

If you are using prototype.js then you can do this:

transport_select.observe('change', function(){
  toggleSelect(transport_select_id)
})

This eliminate (as hope) the problem in cross-browsers

You just needed to cast the unsigned char into a char as the string class doesn't have a constructor that accepts unsigned char:

unsigned char* uc;
std::string s( reinterpret_cast< char const* >(uc) ) ;

However, you will need to use the length argument in the constructor if your byte array contains nulls, as if you don't, only part of the array will end up in the string (the array up to the first null)

size_t len;
unsigned char* uc;
std::string s( reinterpret_cast<char const*>(uc), len ) ;

In case you are working with the Eclipse IDE there is a free plugin Manik-Hotdeploy.

This plugin allows you to connect your eclipse workspace with your wildfly deployment folder. After a maven build your artifact (e.g. war or ear) will be automatically pushed into the deployment folder of your server. Also web content files (e.g. .xhtml .jsf ...) will be hot deployed.

The plugin runs for wildfly, glassfish and payara.

Read the section JBoss/Wildfly Support for more details.

While not strictly nested, you can use common table expressions to reuse previous queries in subsequent ones.

To do this, the form of the statement you are looking for would be

WITH x AS 
(
    SELECT * FROM MyTable
), 
y AS 
(
    SELECT * FROM x
)
SELECT * FROM y

getDrawable() is deprecated. now you can use

imageView.setImageDrawable(ContextCompat.getDrawable(this,R.drawable.msg_status_client_read)) 

You can use the replace function

UPDATE your_table SET field = REPLACE(your_field, 'cat','dog')

The function definition is as follows (got from here):

replace(string text, from text, to text)

and returns the modified text. You can also check out this sql fiddle.

If you specify the disabled attribute then the value you give it must be disabled. (In HTML 5 you may leave off everything except the attribute value. In HTML 4 you may leave off everything except the attribute name.)

If you do not want the control to be disabled then do not specify the attribute at all.

Disabled:

<input type="checkbox" disabled>
<input type="checkbox" disabled="disabled">

Enabled:

<input type="checkbox">

Invalid (but usually error recovered to be treated as disabled):

<input type="checkbox" disabled="1">
<input type="checkbox" disabled="true">
<input type="checkbox" disabled="false">

So, without knowing your template language, I guess you are looking for:

<td><input type="checkbox" name="repriseCheckBox" {checkStat == 1 ? disabled : }/></td>

in kotlin do it as below by using html

HtmlCompat.fromHtml("<html><body><h1>This is Large Heading :-</h1><br>This is normal size<body></html>",HtmlCompat.FROM_HTML_MODE_LEGACY)

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

Edit - This answer is a solution, but a much simpler and proper approach would be setting the tabindex attribute on the canvas element (as suggested by hobberwickey).

You can't focus a canvas element. A simple work around this, would be to make your "own" focus.

var lastDownTarget, canvas;
window.onload = function() {
    canvas = document.getElementById('canvas');

    document.addEventListener('mousedown', function(event) {
        lastDownTarget = event.target;
        alert('mousedown');
    }, false);

    document.addEventListener('keydown', function(event) {
        if(lastDownTarget == canvas) {
            alert('keydown');
        }
    }, false);
}

JSFIDDLE

The question is asked in a misleading manner. "Removing the selected attribute" and "deselecting all options" are entirely different things.

To deselect all options in a documented, cross-browser manner use either

$("select").val([]);

or

// Note the use of .prop instead of .attr
$("select option").prop("selected", false);

During loop, return nothing when certain properties/keys are encountered and continue with the rest:

const loop = product =>
Object.keys(product).map(key => {
    if (key === "_id" || key === "__v") {
        return; 
    }
    return (
        <ul className="list-group">
            <li>
                {product[key]}
                <span>
                    {key}
                </span>
            </li>
        </ul>
    );
});

If any1 in 2017 is wondering how to do this programmatically, there is a way that i don't see in the answers

.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

Redirecting from HTTP to HTTPS with PHP on IIS

I was having trouble getting redirection to HTTPS to work on a Windows server which runs version 6 of MS Internet Information Services (IIS). I’m more used to working with Apache on a Linux host so I turned to the Internet for help and this was the highest ranking Stack Overflow question when I searched for “php redirect http to https”. However, the selected answer didn’t work for me.

After some trial and error, I discovered that with IIS, $_SERVER['HTTPS'] is set to off for non-TLS connections. I thought the following code should help any other IIS users who come to this question via search engine.

<?php
if (! isset($_SERVER['HTTPS']) or $_SERVER['HTTPS'] == 'off' ) {
    $redirect_url = "https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header("Location: $redirect_url");
    exit();
}
?>

Edit: From another Stack Overflow answer, a simpler solution is to check if($_SERVER["HTTPS"] != "on").

The class BooleanUtils supportes the negation of a boolean. You find this class in commons-lang:commons-lang

BooleanUtils.negate(theBoolean)

The most correct way is to use HttpContext.Current.Server.MapPath("~/App_Data");. This means you can only retrieve the path from a method where the HttpContext is available. It makes sense: the App_Data directory is a web project folder structure [1].

If you need the path to ~/App_Data from a class where you don't have access to the HttpContext you can always inject a provider interface using your IoC container:

public interface IAppDataPathProvider
{
    string GetAppDataPath();
}

Implement it using your HttpApplication:

public class AppDataPathProvider : IAppDataPathProvider
{
    public string GetAppDataPath()
    {
        return MyHttpApplication.GetAppDataPath();
    }
}

Where MyHttpApplication.GetAppDataPath looks like:

public class MyHttpApplication : HttpApplication
{
    // of course you can fetch&store the value at Application_Start
    public static string GetAppDataPath()
    {
        return HttpContext.Current.Server.MapPath("~/App_Data");
    }
}

set ansi_nulls off go select * from table t inner join otherTable o on t.statusid = o.statusid go set ansi_nulls on go

I think is good enough. It's clear, it lazy so it will be fast (except maybe the first case when you split the string).

May be helpful for somebody. Mocked method must be of mocked class, created with mock(MyService.class)

Destructors in C++ automatically gets called in the order of their constructions (Derived then Base) only when the Base class destructor is declared virtual.

If not, then only the base class destructor is invoked at the time of object deletion.

Example: Without virtual Destructor

#include <iostream>

using namespace std;

class Base{
public:
  Base(){
    cout << "Base Constructor \n";
  }

  ~Base(){
    cout << "Base Destructor \n";
  }

};

class Derived: public Base{
public:
  int *n;
  Derived(){
    cout << "Derived Constructor \n";
    n = new int(10);
  }

  void display(){
    cout<< "Value: "<< *n << endl;
  }

  ~Derived(){
    cout << "Derived Destructor \n";
  }
};

int main() {

 Base *obj = new Derived();  //Derived object with base pointer
 delete(obj);   //Deleting object
 return 0;

}

Output

Base Constructor
Derived Constructor
Base Destructor

Example: With Base virtual Destructor

#include <iostream>

using namespace std;

class Base{
public:
  Base(){
    cout << "Base Constructor \n";
  }

  //virtual destructor
  virtual ~Base(){
    cout << "Base Destructor \n";

It is recommended to declare base class destructor as virtual otherwise, it causes undefined behavior.

Just adding some addition aspects. Need for setting seed: In the academic world, if one claims that his algorithm achieves, say 98.05% performance in one simulation, others need to be able to reproduce it.

?set.seed

Going through the help file of this function, these are some interesting facts:

(1) set.seed() returns NULL, invisible

(2) "Initially, there is no seed; a new one is created from the current time and the process ID when one is required. Hence different sessions will give different simulation results, by default. However, the seed might be restored from a previous session if a previously saved workspace is restored.", this is why you would want to call set.seed() with same integer values the next time you want a same sequence of random sequence.

Try

SELECT to_char(p1.PA_VALUE,'DD/MM/YYYY') as StartDate,
       to_char(p2.PA_VALUE,'DD/MM/YYYY') as EndDate
   ...

Taking Milad's suggestion a bit further, you can break your document source down and then do another find, continuing until you find the unmatched culprit.

When you are working with many modules (using a CMS), or don't have access to the W3C tool (because you are working locally), this approach is really helpful.

You can use regular expression for the mor detail https://dev.mysql.com/doc/refman/8.0/en/regexp.html

I used this ^([,|.]?[0-9])+$. This is allows handle to the decimal and float number

SELECT
    *
FROM
    mytable
WHERE
    myTextField REGEXP "^([,|.]?[0-9])+$"

Here is how I resolved it.

It is not the most secure way however it solved my problem as security was not an issue on internal servers.

Create a new file say password.txt and store the password for the server where the file will be pasted. Save this to a location on the host server.

scp -W location/password.txt copy_file_location paste_file_location

Cheers!

Is Java smart enough to skip checking bool2 and bool2 if bool1 was evaluated to false?

Its not a matter of being smart, its a requirement specified in the language. Otherwise you couldn't write expressions like.

if(s != null && s.length() > 0)

or

if(s == null || s.length() == 0)

BTW if you use & and | it will always evaluate both sides of the expression.

This was the answer for me, I updated cocoapods and I think that made the PODS_HEADERS_SEARCH_PATHS go away. My solution was similar to this but I used "$(PODS_ROOT)/Headers" – Andrew Aitken

Thank you so much for this answer. I had a hard time looking for ways to fix my problem. Thank you very much.

I've also faced with this error - I forgot to create build.gradle script for library project.

You can also easily compare branches for changed files using for example TortoiseGit. Just click on Browse References and pick the branches you want to compare.

For example if you compare your branch with master you will get as a result list of files that will be changed in master if you decide to merge your-branch into master.

Remmber that you will have different result if you compare master with your-branch and your-branch with master.

I would suggest that you use a timer, but set it to check every 45 seconds, not minute. Otherwise you can run into situations where with heavy load, the check for a particular minute is missed, because between the time the timer triggers and the time your code runs and checks the current time, you might have missed the target minute.

you can 'invoke' alternative bindings on Y this way:

...registered(X, Y), (Y=ct101; Y=ct102; Y=ct103).

Note the parenthesis are required to keep the correct execution control flow. The ;/2 it's the general or operator. For your restricted use you could as well choice the more idiomatic

...registered(X, Y), member(Y, [ct101,ct102,ct103]).

that on backtracking binds Y to each member of the list.

edit I understood with a delay your last requirement. If you want that Y match all 3 values the or is inappropriate, use instead

...registered(X, ct101), registered(X, ct102), registered(X, ct103).

or the more compact

...findall(Y, registered(X, Y), L), sort(L, [ct101,ct102,ct103]).

findall/3 build the list in the very same order that registered/2 succeeds. Then I use sort to ensure the matching.

...setof(Y, registered(X, Y), [ct101,ct102,ct103]).

setof/3 also sorts the result list

If you want to stick with Jquery's .load() method, add something unique to the URL like a JavaScript timestamp. "+new Date().getTime()". Notice I had to add an "&time=" so it does not alter your pid variable.

$('#searchButton').click(function() {
$('#inquiry').load('/portal/?f=searchBilling&pid=' + $('#query').val()+'&time='+new Date().getTime());            
});

In the package explorer, in the upper right corner of the view, there is a little down arrow. Tool tip will say view menu. From that menu, select filters

From there, uncheck .* resources.

So Package Explorer -> View Menu -> Filters -> uncheck .* resources.

With Eclipse Kepler and OS X this is a bit different:

Package Explorer -> Customize View -> Filters -> uncheck .* resources

I think git fetch is what your looking for.

It will pull the changes and objects without committing them to your local repo's index.

They can be merged later with git merge.

Man Page

Edit: Further Explination

Straight from the Git- SVN Crash Course link

Now, how do you get any new changes from a remote repository? You fetch them:

git fetch http://host.xz/path/to/repo.git/ 

At this point they are in your repository and you can examine them using:

git log origin 

You can also diff the changes. You can also use git log HEAD..origin to see just the changes you don't have in your branch. Then if would like to merge them - just do:

git merge origin

Note that if you don't specify a branch to fetch, it will conveniently default to the tracking remote.

Reading the man page is honestly going to give you the best understanding of options and how to use it.

I'm just trying to do this by examples and memory, I don't currently have a box to test out on. You should look at:

git log -p //log with diff

A fetch can be undone with git reset --hard (link) , however all uncommitted changes in your tree will be lost as well as the changes you've fetched.

As other answers pointed out in a more complicated way already, you did already create a list of lists! It's just the odd output of R that confuses (everybody?). Try this:

> str(list_all)
List of 2
 $ :List of 2
  ..$ : num 1
  ..$ : num 2
 $ :List of 2
  ..$ : chr "a"
  ..$ : chr "b"

And the most simple construction would be this:

> str(list(list(1, 2), list("a", "b")))
List of 2
 $ :List of 2
  ..$ : num 1
  ..$ : num 2
 $ :List of 2
  ..$ : chr "a"
  ..$ : chr "b"

text-align aligns text and other inline content. It doesn't align block element children.

To do that, you want to give the element you want aligned a width, with ‘auto’ left and right margins. This is the standards-compliant way that works everywhere except IE5.x.

<div style="width: 50%; margin: 0 auto;">Hello</div>

For this to work in IE6, you need to make sure Standards Mode is on by using a suitable DOCTYPE.

If you really need to support IE5/Quirks Mode, which these days you shouldn't really, it is possible to combine the two different approaches to centering:

<div style="text-align: center">
    <div style="width: 50%; margin: 0 auto; text-align: left">Hello</div>
</div>

(Obviously, styles are best put inside a stylesheet, but the inline version is illustrative.)

after you get the image path, try either of following ways

1. (as you need to set more attr than just the src) build the html and replace to the target region

   $('#target_div').html('<img src="'+ imgPaht +'" width=100 height=100 alt="Hello Image" />');
   

2. you may need to add some delay if changing the "SRC" attr

   setTimeout(function(){///this function fire after 1ms delay
         $('#target_img_tag_id').attr('src',imgPaht);
   }, 1);
   

With jquery

  $("div#id").append('<a href=#>Your LINK TITLE</a>')

With javascript

   var new_a = document.createElement('a');
   new_a.setAttribute("href", "link url here");
   new_a.innerHTML = "your link text";
   //add new link to the DOM
   document.appendChild(new_a);

Could be simplified to this:

SELECT article FROM table1 ORDER BY publish_date DESC FETCH FIRST 20 ROWS ONLY;

You could also add many argument in the ORDER BY that is just comma separated like: ORDER BY publish_date, tab2, tab3 DESC etc...

When the servlet container (like Apache Tomcat) starts up, it will read from the web.xml file (only one per application) if anything goes wrong or shows up an error at container side console, otherwise, it will deploy and load all web applications by using web.xml (so named it as deployment descriptor).

During instantiation phase of the servlet, servlet instance is ready but it cannot serve the client request because it is missing with two pieces of information:
1: context information
2: initial configuration information

Servlet engine creates servletConfig interface object encapsulating the above missing information into it servlet engine calls init() of the servlet by supplying servletConfig object references as an argument. Once init() is completely executed servlet is ready to serve the client request.

Q) In the lifetime of servlet how many times instantiation and initialization happens ??

A)only once (for every client request a new thread is created) only one instance of the servlet serves any number of the client request ie, after serving one client request server does not die. It waits for other client requests ie what CGI (for every client request a new process is created) limitation is overcome with the servlet (internally servlet engine creates the thread).

Q)How session concept works?

A)whenever getSession() is called on HttpServletRequest object

Step 1: request object is evaluated for incoming session ID.

Step 2: if ID not available a brand new HttpSession object is created and its corresponding session ID is generated (ie of HashTable) session ID is stored into httpservlet response object and the reference of HttpSession object is returned to the servlet (doGet/doPost).

Step 3: if ID available brand new session object is not created session ID is picked up from the request object search is made in the collection of sessions by using session ID as the key.

Once the search is successful session ID is stored into HttpServletResponse and the existing session object references are returned to the doGet() or doPost() of UserDefineservlet.

Note:

1)when control leaves from servlet code to client don't forget that session object is being held by servlet container ie, the servlet engine

2)multithreading is left to servlet developers people for implementing ie., handle the multiple requests of client nothing to bother about multithread code

Inshort form:

A servlet is created when the application starts (it is deployed on the servlet container) or when it is first accessed (depending on the load-on-startup setting) when the servlet is instantiated, the init() method of the servlet is called then the servlet (its one and only instance) handles all requests (its service() method being called by multiple threads). That's why it is not advisable to have any synchronization in it, and you should avoid instance variables of the servlet when the application is undeployed (the servlet container stops), the destroy() method is called.

Late contribution but just came across something similar in Python datetime and pandas give different timestamps for the same date.

If you have timezone-aware datetime in pandas, technically, tz_localize(None) changes the POSIX timestamp (that is used internally) as if the local time from the timestamp was UTC. Local in this context means local in the specified timezone. Ex:

import pandas as pd

t = pd.date_range(start="2013-05-18 12:00:00", periods=2, freq='H', tz="US/Central")
# DatetimeIndex(['2013-05-18 12:00:00-05:00', '2013-05-18 13:00:00-05:00'], dtype='datetime64[ns, US/Central]', freq='H')

t_loc = t.tz_localize(None)
# DatetimeIndex(['2013-05-18 12:00:00', '2013-05-18 13:00:00'], dtype='datetime64[ns]', freq='H')

# offset in seconds according to timezone:
(t_loc.values-t.values)//1e9
# array([-18000, -18000], dtype='timedelta64[ns]')

Note that this will leave you with strange things during DST transitions, e.g.

t = pd.date_range(start="2020-03-08 01:00:00", periods=2, freq='H', tz="US/Central")
(t.values[1]-t.values[0])//1e9
# numpy.timedelta64(3600,'ns')

t_loc = t.tz_localize(None)
(t_loc.values[1]-t_loc.values[0])//1e9
# numpy.timedelta64(7200,'ns')

In contrast, tz_convert(None) does not modify the internal timestamp, it just removes the tzinfo.

t_utc = t.tz_convert(None)
(t_utc.values-t.values)//1e9
# array([0, 0], dtype='timedelta64[ns]')

My bottom line would be: stick with timezone-aware datetime if you can or only use t.tz_convert(None) which doesn't modify the underlying POSIX timestamp. Just keep in mind that you're practically working with UTC then.

dir /s/d/a:-d "folderpath*.*" > file.txt

And, lose the /s if you do not need files from subfolders

Based on Tomasz Nurkiewiczs answer, the "problem" is that typescript is typesafe. :) So the document.getElementById() returns the type HTMLElement which does not contain a value property. The subtype HTMLInputElement does however contain the value property.

So a solution is to cast the result of getElementById() to HTMLInputElement like this:

var inputValue = (<HTMLInputElement>document.getElementById(elementId)).value;

<> is the casting operator in typescript. See the question TypeScript: casting HTMLElement.

The resulting javascript from the line above looks like this:

inputValue = (document.getElementById(elementId)).value;

i.e. containing no type information.

Just Simply use

use css code: text-transform: uppercase;

Moving to an existing branch

If you want to move your commits to an existing branch, it will look like this:

git checkout existingbranch
git merge master
git checkout master
git reset --hard HEAD~3 # Go back 3 commits. You *will* lose uncommitted work.
git checkout existingbranch

You can store uncommitted edits to your stash before doing this, using git stash. Once complete, you can retrieve the stashed uncommitted edits with git stash pop

Moving to a new branch

WARNING: This method works because you are creating a new branch with the first command: git branch newbranch. If you want to move commits to an existing branch you need to merge your changes into the existing branch before executing git reset --hard HEAD~3 (see Moving to an existing branch above). If you don't merge your changes first, they will be lost.

Unless there are other circumstances involved, this can be easily done by branching and rolling back.

# Note: Any changes not committed will be lost.
git branch newbranch      # Create a new branch, saving the desired commits
git reset --hard HEAD~3   # Move master back by 3 commits (Make sure you know how many commits you need to go back)
git checkout newbranch    # Go to the new branch that still has the desired commits

But do make sure how many commits to go back. Alternatively, you can instead of HEAD~3, simply provide the hash of the commit (or the reference like origin/master) you want to "revert back to" on the master (/current) branch, e.g:

git reset --hard a1b2c3d4

*1 You will only be "losing" commits from the master branch, but don't worry, you'll have those commits in newbranch!

WARNING: With Git version 2.0 and later, if you later git rebase the new branch upon the original (master) branch, you may need an explicit --no-fork-point option during the rebase to avoid losing the carried-over commits. Having branch.autosetuprebase always set makes this more likely. See John Mellor's answer for details.

Had the same problem with base64. For anyone in the future with the same problem:

url = "data:image/png;base64,iVBORw0KGgoAAAAAAAAyCAYAAAAUYybjAAAgAElE...";

This would work executed from console, but not from within a script:

$img.css("background-image", "url('" + url + "')");

But after playing with it a bit, I came up with this:

var img = new Image();
img.src = url;
$img.css("background-image", "url('" + img.src + "')");

No idea why it works with a proxy image, but it does. Tested on Firefox Dev 37 and Chrome 40.

Hope it helps someone.

EDIT

Investigated a little bit further. It appears that sometimes base64 encoding (at least in my case) breaks with CSS because of line breaks present in the encoded value (in my case value was generated dynamically by ActionScript).

Simply using e.g.:

$img.css("background-image", "url('" + url.replace(/(\r\n|\n|\r)/gm, "") + "')");

works too, and even seems to be faster by a few ms than using a proxy image.

Documentation on UISwitch says:

[mySwitch setOn:NO]; 

In Interface Builder, select your switch and in the Attributes inspector you'll find State which can be set to on or off.

YOu can also try the following

   do {
        try {
            System.out.println("Enter first num: ");
            n1 = Integer.parseInt(input.next());

            System.out.println("Enter second num: ");
            n2 = Integer.parseInt(input.next());

            nQuotient = n1/n2;

            bError = false;
        } 
        catch (Exception e) {
            System.out.println("Error!");
            input.reset();
        }
    } while (bError);

In 9.4.4 using the #>> operator works for me:

select to_json('test'::text) #>> '{}';

To use with a table column:

select jsoncol #>> '{}' from mytable;

Take a look at the java.sql.PreparedStatement class, specifically the function

http://java.sun.com/javase/6/docs/api/java/sql/PreparedStatement.html#setBinaryStream(int,%20java.io.InputStream)

Then take a look at the java.sql.ResultSet class, specifically the function

http://java.sun.com/javase/6/docs/api/java/sql/ResultSet.html#getBinaryStream(int)

Keep in mind that if you are serializing an object into a database, and then you change the object in your code in a new version, the deserialization process can easily fail because your object's signature changed. I once made this mistake with storing a custom Preferences serialized and then making a change to the Preferences definition. Suddenly I couldn't read any of the previously serialized information.

You might be better off writing clunky per property columns in a table and composing and decomposing the object in this manner instead, to avoid this issue with object versions and deserialization. Or writing the properties into a hashmap of some sort, like a java.util.Properties object, and then serializing the properties object which is extremely unlikely to change.

C++ does not provide any way to do it directly. It would entirely depend on what platforms and libraries that you have.

At worst case, you can use the boost::asio library to establish a TCP connection, send the HTTP headers (RFC 2616), and parse the responses directly. Looking at your application needs, this is simple enough to do.

If you are working from a windows forms application this worked for me

"server=localhost; user id=dbuser; password=password; database=dbname; Use Procedure Bodies=false;"

Just add the "Use Procedure Bodies=false" at the end of your connection string.

x=str(input("insert string"))
c=0
for i in x:
   if 'a' in i:
      c=c+1
print(c)        

Iterate over the array and do whatever you want with the individual values.

foreach ($array as $key => $value) {
    echo $key . ' contains ' . $value . '<br/>';
}

As of C++20, yes.

As of C++17, you can use string_view:

constexpr std::string_view sv = "hello, world";

A string_view is a string-like object that acts as an immutable, non-owning reference to any sequence of char objects.

Another simple method is to convert it to json

console.log('connection : %j', myObject);

history.pushState(null, null, document.title);
window.addEventListener('popstate', function () {
    history.pushState(null, null, document.title);
});

This script will overwrite attempts to navigate back and forth with the state of the current page.

Update:

Some users have reported better success with using document.URL instead of document.title:

history.pushState(null, null, document.URL);
window.addEventListener('popstate', function () {
    history.pushState(null, null, document.URL);
});

List<Person> list = new ArrayList<Person>();
Criteria criteria = this.getSessionFactory().getCurrentSession().createCriteria(Person.class);
for (final Object o : criteria.list()) {
    list.add((Person) o);
}

AssemblyVersion

Where other assemblies that reference your assembly will look. If this number changes, other assemblies have to update their references to your assembly! Only update this version, if it breaks backward compatibility. The AssemblyVersion is required.

I use the format: major.minor. This would result in:

[assembly: AssemblyVersion("1.0")]

If you're following SemVer strictly then this means you only update when the major changes, so 1.0, 2.0, 3.0, etc.

AssemblyFileVersion

Used for deployment. You can increase this number for every deployment. It is used by setup programs. Use it to mark assemblies that have the same AssemblyVersion, but are generated from different builds.

In Windows, it can be viewed in the file properties.

The AssemblyFileVersion is optional. If not given, the AssemblyVersion is used.

I use the format: major.minor.patch.build, where I follow SemVer for the first three parts and use the buildnumber of the buildserver for the last part (0 for local build). This would result in:

[assembly: AssemblyFileVersion("1.3.2.254")]

Be aware that System.Version names these parts as major.minor.build.revision!

AssemblyInformationalVersion

The Product version of the assembly. This is the version you would use when talking to customers or for display on your website. This version can be a string, like '1.0 Release Candidate'.

The AssemblyInformationalVersion is optional. If not given, the AssemblyFileVersion is used.

I use the format: major.minor[.patch] [revision as string]. This would result in:

[assembly: AssemblyInformationalVersion("1.0 RC1")]

In angularJS, you can use angular.element which is the lite version of jQuery. You can do pretty much everything with it, so you don't need to include jQuery.

So basically, you can rewrite your code to something like this:

link: function (scope, iElement, iAttrs) {
  var svgTag = angular.element('<svg width="600" height="100" class="svg"></svg>');
  angular.element(svgTag).appendTo(iElement[0]);
  //...
}

var getKeyByDinner = function(obj, dinner) {
    var returnKey = -1;

    $.each(obj, function(key, info) {
        if (info.dinner == dinner) {
           returnKey = key;
           return false; 
        };   
    });

    return returnKey;       

}

jsFiddle.

So long as -1 isn't ever a valid key.

Chaining with the query builder interface in Mongoose 4.

// Build up a query using chaining syntax. Since no callback is passed this will create an instance of Query.
var query = Person.
    find({ occupation: /host/ }).
    where('name.last').equals('Ghost'). // find each Person with a last name matching 'Ghost'
    where('age').gt(17).lt(66).
    where('likes').in(['vaporizing', 'talking']).
    limit(10).
    sort('-occupation'). // sort by occupation in decreasing order
    select('name occupation'); // selecting the `name` and `occupation` fields


// Excute the query at a later time.
query.exec(function (err, person) {
    if (err) return handleError(err);
    console.log('%s %s is a %s.', person.name.first, person.name.last, person.occupation) // Space Ghost is a talk show host
})

See the docs for more about queries.

If you just want to know the position of one specific user after order by field score, you can simply select all row from your table where field score is higher than the current user score. And use row number returned + 1 to know which position of this current user.

Assuming that your table is league_girl and your primary field is id, you can use this:

SELECT count(id) + 1 as rank from league_girl where score > <your_user_score>

Steps to fix this,

1. Install latest version of Android SDK Build-Tools
2. Check if zipalign.exe is available in folder android-sdk\build-tools\ e.g. android-sdk\build-tools\21.1.0\
3. In some older version of android you may not find zipalign.exe. Do not panic, check any other verion in which zipalign is available.
4. Open your project.properties file and configure build-tools to point to the in which zipalign.exe is present. e.g. sdk.buildtools=21.1.0.
5. Restart your eclipse and try exporting again. It should work.

Dim P As String = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().CodeBase)
P = New Uri(P).LocalPath

You do not need to pass the size parameter, just declare Varchar already understands that it is MAX like:

cmd.Parameters.Add("@blah",SqlDbType.VarChar).Value = "some large text";

Another way of achieving it would be to temporary edit the gitignore file, add the file and then revert back the gitignore. A bit hacky i feel

Try \n\n , it will work! :)

public async Task AjudaAsync(IDialogContext context, LuisResult result){
await context.PostAsync("How can I help you? \n\n 1.To Schedule \n\n 2.Consult");
context.Wait(MessageReceived);
}

I solved a similar problem, where I wanted to find a book by its isbnCode not by your id(primary key).

@Entity
public class Book implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Integer id;
    private String isbnCode;

...

In the repository the method was created like @kamalveer singh mentioned. Note that the method name is findBy+fieldName (in my case: findByisbnCode):

@Repository
public interface BookRepository extends JpaRepository<Book, Integer> {

    Book findByisbnCode(String isbnCode);
}

Then, implemented the method in the service:

@Service
public class BookService {

    @Autowired
    private BookRepository repo;
    
    
    public Book findByIsbnCode(String isbnCode) {
        Book obj = repo.findByisbnCode(isbnCode);
        return obj; 
    }
}

Based on the answer for this question, I created a static class and added these. Thought it might be useful for some people.

public static class RegexConvert
{
    public static string ToAlphaNumericOnly(this string input)
    {
        Regex rgx = new Regex("[^a-zA-Z0-9]");
        return rgx.Replace(input, "");
    }

    public static string ToAlphaOnly(this string input)
    {
        Regex rgx = new Regex("[^a-zA-Z]");
        return rgx.Replace(input, "");
    }

    public static string ToNumericOnly(this string input)
    {
        Regex rgx = new Regex("[^0-9]");
        return rgx.Replace(input, "");
    }
}

Then the methods can be used as:

string example = "asdf1234!@#$";
string alphanumeric = example.ToAlphaNumericOnly();
string alpha = example.ToAlphaOnly();
string numeric = example.ToNumericOnly();

The accepted answer already mentions PEP 238. I just want to add a quick look behind the scenes for those interested in what's going on without reading the whole PEP.

Python maps operators like +, -, * and / to special functions, such that e.g. a + b is equivalent to

a.__add__(b)

Regarding division in Python 2, there is by default only / which maps to __div__ and the result is dependent on the input types (e.g. int, float).

Python 2.2 introduced the __future__ feature division, which changed the division semantics the following way (TL;DR of PEP 238):

• / maps to __truediv__ which must "return a reasonable approximation of the mathematical result of the division" (quote from PEP 238)
• // maps to __floordiv__, which should return the floored result of /

With Python 3.0, the changes of PEP 238 became the default behaviour and there is no more special method __div__ in Python's object model.

If you want to use the same code in Python 2 and Python 3 use

from __future__ import division

and stick to the PEP 238 semantics of / and //.

You could try:

agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)

1. Install mysql connector using the below command.

   pip install mysql-connector-python-rf

2. Use the command to set the privileges.

   ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'very_strong_password'; FLUSH PRIVILEGES;

3. Use the python command to connect to mysql database

   mydb = mysql.connector.connect( host="localhost", user="root", passwd="very_strong_password", auth_plugin='mysql_native_password')

To determine if the array is sparse, it may help to get a proportion of nan values

np.isnan(ndarr).sum() / ndarr.size

If that proportion exceeds a threshold, then use a sparse array, e.g. - https://sparse.pydata.org/en/latest/

Your code and schema are OK. You probably trying on previous version of table.

http://sqlfiddle.com/#!2/9dc64/1/0

Your table even has no UNIQUE, so that error is impossible on that table.

Backup data from that table, drop it and re-create.

Maybe you tried to run that CREATE TABLE IF NOT EXIST. It was not created, you have old version, but there was no error because of IF NOT EXIST.

You may run SQL like this to see current table structure:

DESCRIBE my_table;

Edit - added later:

Try to run this:

DROP TABLE `my_table`; --make backup - it deletes table

CREATE TABLE `my_table` (
  `number` int(11) NOT NULL,
  `name` varchar(50) NOT NULL,
  `money` int(11) NOT NULL,
  PRIMARY KEY (`number`,`name`),
  UNIQUE (`number`, `name`) --added unique on 2 rows
) ENGINE=MyISAM;

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

Download android SDK from developer.android.com (its currently a 149mb file for windows OS). It is worthy of note that android has removed the sdkmanager GUI but has a command line version of the sdkmanager in the bin folder which is located inside the tools folder.

1. When inside the bin folder, hold down the shift key, right click, then select open command line here. Shift+right click >> open command line here.
2. When the command line opens, type sdkmanager click enter.
3. Then run type sdkmanager (space), double hyphen (--), type list sdkmanager --list (this lists all the packages in the SDK manager)
4. Type sdkmanager (space) then package name, press enter. Eg. sdkmanager platform-tools (press enter) It will load licence agreement. With options (y/n). Enter y to accept and it will download the package you specified.

I hope this helps. :)

var seconds = 0;
setInterval(function () {
  seconds++;
}, 1000);

There you go, now you have a variable counting seconds elapsed. Since I don't know the context, you'll have to decide whether you want to attach that variable to an object or make it global.

Set interval is simply a function that takes a function as it's first parameter and a number of milliseconds to repeat the function as it's second parameter.

You could also solve this by saving and comparing times.

EDIT: This answer will provide very inconsistent results due to things such as the event loop and the way browsers may choose to pause or delay processing when a page is in a background tab. I strongly recommend using the accepted answer.

Confirm in API documentation http://api.jquery.com/jQuery.each/ say:

We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

and this is my example http://jsfiddle.net/r6jqP/

(function($){
    $('#go').on('click',function(){
        var i=0,
            all=0;
        $('li').each(function(){
             all++;
             if($('#mytext').val()=='continue')return true;
             i++;
             if($('#mytext').val()==$(this).html()){
                 return false;
             }
        });
        alert('Iterazione : '+i+' to '+all);
    });
}(jQuery));

Set your .on listener to check for specific select2 events. The "change" event is the same as usual but the others are specific to the select2 control thus:

• change
• select2-opening
• select2-open
• select2-close
• select2-highlight
• select2-selecting
• select2-removed
• select2-loaded
• select2-focus

The names are self-explanatory. For example, select2-focus fires when you give focus to the control.

There are moduli other than powers of 2 for which efficient algorithms exist.

For example, if x is 32 bits unsigned int then x % 3 = popcnt (x & 0x55555555) - popcnt (x & 0xaaaaaaaa)

This solution worked for me. This will return you the android device's language (not the app's local language)

String locale = getApplicationContext().getResources().getConfiguration().locale.getLanguage();

This will return "en" or "de" or "fr" or whatever your device language is set to.

Yes, that's it.

It's just the dot version when you want to access elements of a struct/class that is a pointer instead of a reference.

struct foo
{
  int x;
  float y;
};

struct foo var;
struct foo* pvar;
pvar = malloc(sizeof(pvar));

var.x = 5;
(&var)->y = 14.3;
pvar->y = 22.4;
(*pvar).x = 6;

That's it!

BATCH LOAD - OK, so after having my previous reply deleted for just using links I have updated with the code I managed to get working. Appreciate anyone to simplify / correct / refine / put in function etc as I'm still learning this stuff, but I got batch member list add working :)

There is a workaround.

1. Import excel sheet with numbers as float (default).
2. After importing, Goto Table-Design
3. Change DataType of the column from Float to Int or Bigint
4. Save Changes
5. Change DataType of the column from Bigint to any Text Type (Varchar, nvarchar, text, ntext etc)
6. Save Changes.

That's it.

The size_t type is the type returned by the sizeof operator. It is an unsigned integer capable of expressing the size in bytes of any memory range supported on the host machine. It is (typically) related to ptrdiff_t in that ptrdiff_t is a signed integer value such that sizeof(ptrdiff_t) and sizeof(size_t) are equal.

When writing C code you should always use size_t whenever dealing with memory ranges.

The int type on the other hand is basically defined as the size of the (signed) integer value that the host machine can use to most efficiently perform integer arithmetic. For example, on many older PC type computers the value sizeof(size_t) would be 4 (bytes) but sizeof(int) would be 2 (byte). 16 bit arithmetic was faster than 32 bit arithmetic, though the CPU could handle a (logical) memory space of up to 4 GiB.

Use the int type only when you care about efficiency as its actual precision depends strongly on both compiler options and machine architecture. In particular the C standard specifies the following invariants: sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) placing no other limitations on the actual representation of the precision available to the programmer for each of these primitive types.

Note: This is NOT the same as in Java (which actually specifies the bit precision for each of the types 'char', 'byte', 'short', 'int' and 'long').

Pending design decision. Meanwhile, use exclude()

The Django issue tracker has the remarkable entry #5763, titled "Queryset doesn't have a "not equal" filter operator". It is remarkable because (as of April 2016) it was "opened 9 years ago" (in the Django stone age), "closed 4 years ago", and "last changed 5 months ago".

Read through the discussion, it is interesting. Basically, some people argue __ne should be added while others say exclude() is clearer and hence __ne should not be added.

(I agree with the former, because the latter argument is roughly equivalent to saying Python should not have != because it has == and not already...)

For me this worked (basically pom.xml level global properties):

<properties>
    <sonar.exclusions>**/Name*.java</sonar.exclusions>
</properties>

According to: http://docs.sonarqube.org/display/SONAR/Narrowing+the+Focus#NarrowingtheFocus-Patterns

It appears you can either end it with ".java" or possibly "*"

to get the java classes you're interested in.

For methods which may fail, that is you specify boolean as return type, I would use the prefix try:

if (tryCreateFreshSnapshot())
{
  // ...
}

For all other cases use prefixes like is.. has.. was.. can.. allows.. ..

Since these are member functions, call it as a member function on the instance, self.

def isNear(self, p):
    self.distToPoint(p)
    ...

You can use Iterator<String> to iterate the elements of the ArrayList<String>:

ArrayList<String> list = new ArrayList<>();
String[] array = new String[list.size()];
int i = 0;
for (Iterator<String> iterator = list.iterator(); iterator.hasNext(); i++) {
    array[i] = iterator.next();
}

Now you can retrive elements from String[] using any Loop.

If strMyString.Contains("Something") or strMyString.Contains("Something2") Then

End if

The error indicates that the compiler thinks you want to do a bitwise OR on a Boolean and a string. Which of course won't work.

list = [1, 2, 3, 4, 5]
for i in list[0:-1]:
    print(i, end=', ')
print(list[-1])

do for loops really take that much longer to run?

was trying to make something that printed all str values in a list separated by commas, inserting "and" before the last entry and came up with this:

spam = ['apples', 'bananas', 'tofu', 'cats']
for i in spam[0:-1]:
    print(i, end=', ')
print('and ' + spam[-1])

Maxdepth

I found it works nicely with Jim Lewis's answer just add a bit like this:

$ export DIR=/path/dir && cd $DIR && chmod -R +x *
$ find . -maxdepth 1 -type f -name '*.sh' -exec {} \; > results.out

Sort Order

If you want to execute in sort order, modify it like this:

$ export DIR=/path/dir && cd $DIR && chmod -R +x *
find . -maxdepth 2 -type f -name '*.sh' | sort | bash > results.out

Just for an example, this will execute with following order:

bash: 1: ./assets/main.sh
bash: 2: ./builder/clean.sh
bash: 3: ./builder/concept/compose.sh
bash: 4: ./builder/concept/market.sh
bash: 5: ./builder/concept/services.sh
bash: 6: ./builder/curl.sh
bash: 7: ./builder/identity.sh
bash: 8: ./concept/compose.sh
bash: 9: ./concept/market.sh
bash: 10: ./concept/services.sh
bash: 11: ./product/compose.sh
bash: 12: ./product/market.sh
bash: 13: ./product/services.sh
bash: 14: ./xferlog.sh

Unlimited Depth

If you want to execute in unlimited depth by certain condition, you can use this:

export DIR=/path/dir && cd $DIR && chmod -R +x *
find . -type f -name '*.sh' | sort | bash > results.out

then put on top of each files in the child directories like this:

#!/bin/bash
[[ "$(dirname `pwd`)" == $DIR ]] && echo "Executing `realpath $0`.." || return

and somewhere in the body of parent file:

if <a condition is matched>
then
    #execute child files
    export DIR=`pwd`
fi

If using PhpStorm 2019 and higher

File > Settings > Editor > General

There is'Soft-warp files' input under the 'Soft Warps' Header.

*.md; *.txt; *.rst; .adoc;

Add the file types to this field in which files you want them to be used.

*.md; *.txt; *.rst; .adoc;.php;*.js

df.withColumnRenamed('age', 'age2')

clearInterval()

Note, you can start and pause your code with this capability. The name is a bit deceptive, since it says CLEAR, but it doesn't clear anything. It actually pauses.

Test with this code:

HTML:

<div id='count'>100</div>
<button id='start' onclick='start()'>Start</button>
<button id='stop' onclick='stop()'>Stop</button>

JavaScript:

let count;

function start(){
 count = setInterval(timer,100)  /// HERE WE RUN setInterval()
}

function timer(){
  document.getElementById('count').innerText--;
}


function stop(){
  clearInterval(count)   /// here we PAUSE  setInterval()  with clearInterval() code
}

Make sure all your links that you want to stop have href="#!" (or anything you want, really), and then use this:

jq('body').on('click.stop_link', 'a[href="#!"]',
function(event) {
     event.preventDefault();
});

Sometimes, the plt.tight_layout() doesn't give me the best view or the view I want. Then why don't plot with arbitrary margin first and do fixing the margin after plot? Since we got nice WYSIWYG from there.

import matplotlib.pyplot as plt

fig,ax = plt.subplots(figsize=(8,8))

plt.plot([2,5,7,8,5,3,5,7,])
plt.show()

Then paste settings into margin function to make it permanent:

fig,ax = plt.subplots(figsize=(8,8))

plt.plot([2,5,7,8,5,3,5,7,])
fig.subplots_adjust(
    top=0.981,
    bottom=0.049,
    left=0.042,
    right=0.981,
    hspace=0.2,
    wspace=0.2
)
plt.show()

After instaling the package you need to add the newtonsoft.json.dll into assemble path by runing the flowing command.

Before we can use our assembly, we have to add it to the global assembly cache (GAC). Open the Visual Studio 2008 Command Prompt again (for Vista/Windows7/etc. open it as Administrator). And execute the following command. gacutil /i d:\myMethodsForSSIS\myMethodsForSSIS\bin\Release\myMethodsForSSIS.dll

Try this example

CREATE PROCEDURE MyProc
BEGIN
    --Stored Procedure variables
    Declare @maxOr int; 
    Declare @maxCa int; 

    --Getting query result in the variable (first variant of syntax)
    SET @maxOr = (SELECT MAX(orId) FROM [order]); 

    --Another variant of seting variable from query
    SELECT @maxCa=MAX(caId) FROM [cart]; 

    --Updating record through the variable
    INSERT INTO [order_cart] (orId,caId)
    VALUES(@maxOr, @maxCa); 

    --return values to the program as dataset
    SELECT
       @maxOr AS maxOr,
       @maxCa AS maxCa

    -- return one int value as "return value"
    RETURN @maxOr
END
GO

EXEC MyProc

After have read all the above, I have found that there could be another reason for this.

In my case:

react-native-cli: 2.0.1

react-native: 0.60.4

and following structure:

First has to be noted that index.android is not been update in Android Studio when the build run by Metro builder( react-native run-android) so it has to be done manually. Also in Android studio does not "read" the

app.json(created by default together with index.js, that renamed index.android.js):

 {
    "name": "authApp",
    "displayName": "authApp"
 }

and so this like

(in my case)

import {authApp as appName} from './app.json';

cause the fact that android studio does not know what authApp refer to. I fix for the moment referring to the app name with its string name and not using that import from app.json:

AppRegistry.registerComponent('authApp', () => MyApp);

In my case i have changed the root folder in which the Eclipse project were stored. I have discovered tha when i have runned :

cat .plugins/org.eclip.resources/.projects/<projectname>/.location 

The __init__ function is setting up all the member variables in the class. So once your bicluster is created you can access the member and get a value back:

mycluster = bicluster(...actual values go here...)
mycluster.left # returns the value passed in as 'left'

Check out the Python Docs for some info. You'll want to pick up an book on OO concepts to continue learning.

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex on the row container and at least making sure your middle container on the row has a flex-grow value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow properties applied, middle container only needs 1 for flex-grow).

Here's a pic of what I was trying to do and sample code for how I solved it.

.row {
  background: lightgray;
  height: 30px;
  width: 100%;
  display: flex;
  align-items:flex-end;
  margin-top:5px;
}
.left {
  background:lightblue;
}
.separator{
  flex-grow:1;
  border-bottom:dotted 2px black;
}
.right {
  background:coral;
}

<div class="row">
  <div class="left">Left</div>
  <div class="separator"></div>
  <div class="right">Right With Text</div>
</div>
<div class="row">
  <div class="left">Left With More Text</div>
  <div class="separator"></div>
  <div class="right">Right</div>
</div>
<div class="row">
  <div class="left">Left With Text</div>
  <div class="separator"></div>
  <div class="right">Right With More Text</div>
</div>

Here's an answer http://wiki.python.org/moin/DictionaryKeys

What would go wrong if you tried to use lists as keys, with the hash as, say, their memory location?

Looking up different lists with the same contents would produce different results, even though comparing lists with the same contents would indicate them as equivalent.

What about Using a list literal in a dictionary lookup?

http://en.wikipedia.org/wiki/Post/Redirect/Get

The most common way to implement this pattern in ASP.Net is to use Response.Redirect(Request.RawUrl)

Consider the differences between Redirect and Transfer. Transfer really isn't telling the browser to forward to a clear form, it's simply returning a cleared form. That may or may not be what you want.

Response.Redirect() does not a waste round trip. If you post to a script that clears the form by Server.Transfer() and reload you will be asked to repost by most browsers since the last action was a HTTP POST. This may cause your users to unintentionally repeat some action, eg. place a second order which will have to be voided later.

Just to help those in a similar situation to myself...

This can be caused when a dependent library has accidentally bundled an old version of slf4j. In my case, it was tika-0.8. See https://issues.apache.org/jira/browse/TIKA-556

The workaround is exclude the component and then manually depends on the correct, or patched version.

EG.

<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika-parsers</artifactId>
    <version>0.8</version>
    <exclusions>
        <exclusion>
            <!-- NOTE: Version 4.2 has bundled slf4j -->
            <groupId>edu.ucar</groupId>
            <artifactId>netcdf</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <!-- Patched version 4.2-min does not bundle slf4j -->
    <groupId>edu.ucar</groupId>
    <artifactId>netcdf</artifactId>
    <version>4.2-min</version>
</dependency>

I was able to go around the whole thing by replacing the context reference from this or Context.this to getapplicationcontext.

What about summing both extremities? It would cut time in half. Like so:

1, 2, 3, 4, 5, 6, 7, 8; sum = 0

2, 3, 4, 5, 6, 7; sum = 10

3, 4, 5, 6; sum = 19

4, 5; sum = 28

sum = 37

One algorithm could be:

function sum_array(arr){
    let sum = 0,
        length = arr.length,
        half = Math.floor(length/2)

    for (i = 0; i < half; i++) {
        sum += arr[i] + arr[length - 1 - i]
    }
    if (length%2){
        sum += arr[half]
    }
    return sum
}

It performs faster when I test it on the browser with performance.now(). I think this is a better way. What do you guys think?

_{Note: This is not a duplicate, because the OP is aware that the image from cv2.imread is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)}

To illustrate, I've opened up this same color JPEG image:

once using the conversion

img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

and another by loading it in gray scale mode

img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom

I've summed up the diff too to see

import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image

I tried all cv2.imread() modes

Among all the IMREAD_ modes for cv2.imread(), only IMREAD_COLOR and IMREAD_ANYCOLOR can be converted using COLOR_BGR2GRAY, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE

The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)

Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.

In brief, let's not mix the versions and types in the processing pipeline.

So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

If you want to convert b'\x61' to 97 or '0x61', you can try this:

[python3.5]
>>>from struct import *
>>>temp=unpack('B',b'\x61')[0] ## convert bytes to unsigned int
97
>>>hex(temp) ##convert int to string which is hexadecimal expression
'0x61'

Reference:https://docs.python.org/3.5/library/struct.html

A simple function to get UNIX Epoch time.

NOTE: This function assumes the input date time is in UTC format (Refer to comments here).

def utctimestamp(ts: str, DATETIME_FORMAT: str = "%d/%m/%Y"):
    import datetime, calendar
    ts = datetime.datetime.utcnow() if ts is None else datetime.datetime.strptime(ts, DATETIME_FORMAT)
    return calendar.timegm(ts.utctimetuple())

Usage:

>>> utctimestamp("01/12/2011")
1322697600
>>> utctimestamp("2011-12-01", "%Y-%m-%d")
1322697600

Because of the way the function is called (i.e. as a simple call to a function variable), this is the global object (for which window is an alias in browsers). Use the obj parameter instead.

Also, creating a jQuery object and the using its attr() method for obtaining an element ID is inefficient and unnecessary. Just use the element's id property, which works in all browsers.

function showHideOther(obj){ 
    var sel = obj.options[obj.selectedIndex].value;
    var ID = obj.id;

    if (sel == 'other') { 
        $(obj).html("<input type='text' name='" + ID + "' id='" + ID + "' />");
    } else {
        $(obj).css({'display' : 'none'});
    }
}

You can also get timeout errors based on silly typos. e.g This seemingly innocuous mistake:

describe('Something', () => {
  it('Should do something', () => {
    expect(1).toEqual(1)
  })

  it('Should do nothing', something_that_does_not_exist => {
    expect(1).toEqual(1)
  })
})

Produces the following error:

FAIL src/TestNothing.spec.js (5.427s)
  ? Something › Should do nothing

    Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.
      
      at node_modules/jest-jasmine2/build/queue_runner.js:68:21
      at Timeout.callback [as _onTimeout] (node_modules/jsdom/lib/jsdom/browser/Window.js:678:19)

Whilst the code sample posted doesn't suffer from this it might be a cause of failures elsewhere. Also note that I'm not setting a timeout for anything anywhere - either here or in the config. The 5000ms is just the default setting.

In order to reuse a single confirmation dialog implementation in a multi-module application, the dialog must be implemented in a separate module. Here's one way of doing this with Material Design and FxFlex, though both of those can be trimmed back or replaced.

First the shared module (./app.module.ts):

import {NgModule} from '@angular/core';
import {CommonModule} from '@angular/common';
import {MatDialogModule, MatSelectModule} from '@angular/material';
import {ConfirmationDlgComponent} from './confirmation-dlg.component';
import {FlexLayoutModule} from '@angular/flex-layout';

@NgModule({
   imports: [
      CommonModule,
      FlexLayoutModule,
      MatDialogModule
   ],
   declarations: [
      ConfirmationDlgComponent
   ],
   exports: [
      ConfirmationDlgComponent
   ],
   entryComponents: [ConfirmationDlgComponent]
})

export class SharedModule {
}

And the dialog component (./confirmation-dlg.component.ts):

import {Component, Inject} from '@angular/core';
import {MAT_DIALOG_DATA} from '@angular/material';

@Component({
   selector: 'app-confirmation-dlg',
   template: `
      <div fxLayoutAlign="space-around" class="title colors" mat-dialog-title>{{data.title}}</div>
      <div class="msg" mat-dialog-content>
         {{data.msg}}
      </div>
      <a href="#"></a>
      <mat-dialog-actions fxLayoutAlign="space-around">
         <button mat-button [mat-dialog-close]="false" class="colors">No</button>
         <button mat-button [mat-dialog-close]="true" class="colors">Yes</button>
      </mat-dialog-actions>`,
   styles: [`
      .title {font-size: large;}
      .msg {font-size: medium;}
      .colors {color: white; background-color: #3f51b5;}
      button {flex-basis: 60px;}
   `]
})
export class ConfirmationDlgComponent {
   constructor(@Inject(MAT_DIALOG_DATA) public data: any) {}
}

Then we can use it in another module:

import {FlexLayoutModule} from '@angular/flex-layout';
import {NgModule} from '@angular/core';
import {GeneralComponent} from './general/general.component';
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
import {CommonModule} from '@angular/common';
import {MaterialModule} from '../../material.module';

@NgModule({
   declarations: [
      GeneralComponent
   ],
   imports: [
      FlexLayoutModule,
      MaterialModule,
      CommonModule,
      NgbModule.forRoot()
   ],
   providers: []
})
export class SystemAdminModule {}

The component's click handler uses the dialog:

import {Component} from '@angular/core';
import {ConfirmationDlgComponent} from '../../../shared/confirmation-dlg.component';
import {MatDialog} from '@angular/material';

@Component({
   selector: 'app-general',
   templateUrl: './general.component.html',
   styleUrls: ['./general.component.css']
})
export class GeneralComponent {

   constructor(private dialog: MatDialog) {}

   onWhateverClick() {
      const dlg = this.dialog.open(ConfirmationDlgComponent, {
         data: {title: 'Confirm Whatever', msg: 'Are you sure you want to whatever?'}
      });

      dlg.afterClosed().subscribe((whatever: boolean) => {
         if (whatever) {
            this.whatever();
         }
      });
   }

   whatever() {
      console.log('Do whatever');
   }
}

Just using the this.modal.open(MyComponent); as you did won't return you an object whose events you can subscribe to which is why you can't get it to do something. This code creates and opens a dialog whose events we can subscribe to.

If you trim back the css and html this is really a simple component, but writing it yourself gives you control over its design and layout whereas a pre-written component will need to be much more heavyweight to give you that control.

The most probable cause is that the content displaying over the popover has a higher z-index. Without the precise code/style, I can offer two options :

You should try pinpointing the exact elements with a web inspector (usually F12 on your favorite browser) and check their actual z-index.

If you find this value, you can set it lower than the popover which is z-index: 1010; by default

Or the other approach, not as good, would be to increase the z-index of the popover. You can do that either with the @zindexPopover in the Less files or directly by overriding

.popover {
    z-index: 1010; /* A value higher than 1010 that solves the problem */
}

If you can't find a solution, you should try reproducing the bug in something like this jsfiddle - you will probably resolve the problem while trying to get the bug.

If you are using jQuery :

$(td).attr("title", "One \n Two \n Three");

will work.

tested in IE-9 : working.

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

This will probably not make me a lot of new friends, but it should be added that the C# people have a different guideline: The enum instances are "Pascal case" (upper/lower case mixed). See stackoverflow discussion and MSDN Enumeration Type Naming Guidelines.

As we are exchanging data with a C# system, I am tempted to copy their enums exactly, ignoring Java's "constants have uppercase names" convention. Thinking about it, I don't see much value in being restricted to uppercase for enum instances. For some purposes .name() is a handy shortcut to get a readable representation of an enum constant and a mixed case name would look nicer.

So, yes, I dare question the value of the Java enum naming convention. The fact that "the other half of the programming world" does indeed use a different style makes me think it is legitimate to doubt our own religion.

The code you have is a white with low opacity.

If something white with a low opacity is above something black, you end up with a lighter shade of gray. Above red? Lighter red, etc. That is how opacity works.

Here is a simple demo.

If you want it to look 'more white', make it less opaque:

background:rgba(255,255,255, 0.9);

Demo

I think I've found a better solution than the accepted answer. The alternative solutions weren't working for me and I didn't want to have to work in binary mode all the time. Fortunately this seems to get the job done and I haven't encountered any nasty side-effects yet: preserve missing end-of-line at end of text files. I just added the whole thing to my ~/.vimrc.

For something really basic use this:

<a href="#middle">Go To Middle</a>

Or for something simple in javascript check out this jQuery plugin ScrollTo. Quite useful for scrolling smoothly.

First off the warning is generated by the variable definition in the source file not the header file. The header can stay pristine and should, since you might be using something like doxygen to generate the API-documentation.

I will assume that you have completely different implementation in source files. In these cases you can either comment out the offending parameter or just write the parameter.

Example:

func(int a, int b)
{
    b;
    foo(a);
}

This might seem cryptic, so defined a macro like UNUSED. The way MFC did it is:

#ifdef _DEBUG
#define UNUSED(x)
#else
#define UNUSED(x) x
#endif

Like this you see the warning still in debug builds, might be helpful.

This method will return the selected value for the drop down,

public static String getSelected_visibleText(WebDriver driver, String elementType, String value)
  {
    WebElement element = Webelement_Finder.webElement_Finder(driver, elementType, value);
   Select Selector = new Select(element);
    Selector.getFirstSelectedOption();
    String textval=Selector.getFirstSelectedOption().getText();
    return textval;
  }

Meanwhile

String textval=Selector.getFirstSelectedOption();

element.getText();

Will return all the elements in the drop down.

if you want to make use of lamdas and make it a bit easier to read

  List<Map<String,String>> results;

  Comparator<Map<String,String>> sortByName = Comparator.comparing(x -> x.get("Name"));

  public void doSomething(){
    results.sort(sortByName)
  }

Hai sridhar, I found an answer for your prob

ClientScript.RegisterClientScriptBlock(GetType(), "sas", "<script> alert('Inserted successfully');</script>", true);

change false to true

or try this

ScriptManager.RegisterClientScriptBlock(ursavebuttonID, typeof(LinkButton or button), "sas", "<script> alert('Inserted successfully');</script>", true);

Here is an example of passing mode as optional parameter

void myfunc(int blah, int mode = 0)
{
    if (mode == 0)
        do_something();
     else
        do_something_else();
}

you can call myfunc in both ways and both are valid

myfunc(10);     // Mode will be set to default 0
myfunc(10, 1);  // Mode will be set to 1

Actually, x is post-decrementing and with that condition is being checked. It's not -->, it's (x--) > 0

Note: value of x is changed after the condition is checked, because it post-decrementing. Some similar cases can also occur, for example:

-->    x-->0
++>    x++>0
-->=   x-->=0
++>=   x++>=0

This was for my own project and I'm sharing it here too.

I know this question has already been answered, but having dealt with layout a fair bit, I wanted to add an alternative answer that solves a few traditional problems with floating elements...

You can see the updated example in action here.

http://jsfiddle.net/Sohnee/EMaDB/1/

It makes no difference whether you are using HTML 4.01 or HTML5 with semantic elements (you will need to declare the left and right containers as display:block if they aren't already).

CSS

.left {
    background-color: Red;
    float: left;
    width: 50%;
}

.right {
    background-color: Aqua;
    margin-left: 50%;
}

HTML

<div class="left">
    <p>I have updated this example to show a great way of getting a two column layout.</p>
</div>
<div class="right">
    <ul>
        <li>The columns are in the right order semantically</li>
        <li>You don't have to float both columns</li>
        <li>You don't get any odd wrapping behaviour</li>
        <li>The columns are fluid to the available page...</li>
        <li>They don't have to be fluid to the available page - but any container!</li>
    </ul>
</div>

There is also a rather neat (albeit newer) addition to CSS that allows you to layout content into columns without all this playing around with divs:

column-count: 2;

A general tip , if you get confused by any of new JS syntax and how it will compile , you can check babel. For example copying your code in babel and selecting the es2015 preset will give an output like this

handleChange = function handleChange(field) {
 return function (e) {
 e.preventDefault();
  // Do something here
   };
 };
