This is based on the assumption that you're getting an error about the date format, such as an invalid month value or non-numeric character when numeric expected.

Dates stored in the database do not have formats. When you query the date your client is formatting the date for display, as 4/16/2011. Normally the same date format is used for selecting and updating dates, but in this case they appear to be different - so your client is apparently doing something more complicated that SQL*Plus, for example.

When you try to update it it's using a default date format model. Because of how it's displayed you're assuming that is MM/DD/YYYY, but it seems not to be. You could find out what it is, but it's better not to rely on the default or any implicit format models at all.

Whether that is the problem or not, you should always specify the date model:

UPDATE PASOFDATE SET ASOFDATE = TO_DATE('11/21/2012', 'MM/DD/YYYY');

Since you aren't specifying a time component - all Oracle DATE columns include a time, even if it's midnight - you could also use a date literal:

UPDATE PASOFDATE SET ASOFDATE = DATE '2012-11-21';

You should maybe check that the current value doesn't include a time, though the column name suggests it doesn't.

Edit: due to post-tag 'oracle', the first two queries become irrelevant, leaving 3rd query for oracle.

For MySQL:

SELECT YEAR(ASOFDATE) FROM PASOFDATE

Editted: In anycase if your date is a String, let's convert it into a proper date format. And select the year out of it.

SELECT YEAR(STR_TO_DATE(ASOFDATE, '%d-%b-%Y')) FROM PSASOFDATE

Since you are trying Toad, can you check the following code:

For Oracle:

SELECT EXTRACT (TO_DATE(YEAR, 'MM/DD/YY') FROM ASOFDATE) FROM PSASOFDATE;

Another way would be to open terminal ctrl+` execute node. Now you have a node REPL active. You can now send your file or selected text to terminal. In order to do that open VSCode command pallete (F1 or ctrl+shift+p) and execute >run selected text in active terminal or >run active file in active terminal.

If you need a clean REPL before executing your code you will have to restart the node REPL. This is done when in the Terminal with the node REPL ctrl+c ctrl+c to exit it and typing node to start new.

You could probably key bind the command pallete commands to whatever key you wish.

PS: node should be installed and in your path

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

Quote from Conda for Data Science article onto Continuum's website:

Conda vs pip

Python programmers are probably familiar with pip to download packages from PyPI and manage their requirements. Although, both conda and pip are package managers, they are very different:

• Pip is specific for Python packages and conda is language-agnostic, which means we can use conda to manage packages from any language Pip compiles from source and conda installs binaries, removing the burden of compilation
• Conda creates language-agnostic environments natively whereas pip relies on virtualenv to manage only Python environments Though it is recommended to always use conda packages, conda also includes pip, so you don’t have to choose between the two. For example, to install a python package that does not have a conda package, but is available through pip, just run, for example:

conda install pip
pip install gensim

For Java 6-7, the best option is to borrow code from the Android repository. It has no dependencies.

The answer was given already by either Sivasubramaniam Arunachalam or ch3ka.

I am just adding a performances view of the answer.

dicttest={}
dicttest['ligne1']={'ligne1.1':'test','ligne1.2':'test8'}
%timeit dicttest['ligne1']['ligne1.1']
%timeit dicttest.get('ligne1').get('ligne1.1')

gives us :

112 ns ± 29.7 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

235 ns ± 9.82 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

Are you sure you want to do this? In essence, you're duplicating the data that is in the three original columns. From that point on, you'll need to make sure that the data in the combined field matches the data in the first three columns. This is more overhead for your application, and other processes that update the system will need to understand the relationship.

If you need the data, why not select in when you need it? The SQL for selecting what would be in that field would be:

SELECT CONCAT(zipcode, ' - ', city, ', ', state) FROM Table;

This way, if the data in the fields changes, you don't have to update your combined field.

May come in handy to check syntax of Nginx's configuration files by running:

nginx -t -c /etc/nginx/nginx.conf

The easiest way would be to use the readme.html file that comes with every WordPress installation (unless you deleted it).

http://example.com/readme.html

Note: it looks like the readme.html file no longer outputs the current WordPress version. So, there is no way, for now, to see the current WordPress version without logging into the dashboard.

This question is full of misunderstandings. First lets understand the question fully. The asker wants to get the same result as for when running the MS SQL Server function DATEDIFF ( datepart , startdate , enddate ) where datepart takes dd, mm, or yy.

This function is defined by:

This function returns the count (as a signed integer value) of the specified datepart boundaries crossed between the specified startdate and enddate.

That means how many day boundaries, month boundaries, or year boundaries, are crossed. Not how many days, months, or years it is between them. That's why datediff(yy, '2010-04-01', '2012-03-05') is 2, and not 1. There is less than 2 years between those dates, meaning only 1 whole year has passed, but 2 year boundaries have crossed, from 2010 to 2011, and from 2011 to 2012.

The following are my best attempt at replicating the logic correctly.

-- datediff(dd`, '2010-04-01', '2012-03-05') = 704 // 704 changes of day in this interval
select ('2012-03-05'::date - '2010-04-01'::date );
-- 704 changes of day

-- datediff(mm, '2010-04-01', '2012-03-05') = 23  // 23 changes of month
select (date_part('year', '2012-03-05'::date) - date_part('year', '2010-04-01'::date)) * 12 + date_part('month', '2012-03-05'::date) - date_part('month', '2010-04-01'::date)
-- 23 changes of month

-- datediff(yy, '2010-04-01', '2012-03-05') = 2   // 2 changes of year
select date_part('year', '2012-03-05'::date) - date_part('year', '2010-04-01'::date);
-- 2 changes of year

Using 2.7:

from functools import partial
from random import randint

for roll in iter(partial(randint, 1, 8), 1):
    print 'you rolled: {}'.format(roll)
print 'oops you rolled a 1!'

you rolled: 7
you rolled: 7
you rolled: 8
you rolled: 6
you rolled: 8
you rolled: 5
oops you rolled a 1!

Then change the "oops" print to a raise SystemExit

One datestamp is already in the _id object, representing insert time

So if the insert time is what you need, it's already there:

Create your database by inserting items

> db.penguins.insert({"penguin": "skipper"})
> db.penguins.insert({"penguin": "kowalski"})

Lets make that database the one we are on now

> use penguins
switched to db penguins

Get the rows back:

> db.penguins.find()
{ "_id" : ObjectId("5498da1bf83a61f58ef6c6d5"), "penguin" : "skipper" }
{ "_id" : ObjectId("5498da28f83a61f58ef6c6d6"), "penguin" : "kowalski" }

Get each row in yyyy-MM-dd HH:mm:ss format:

> db.penguins.find().forEach(function (doc){ d = doc._id.getTimestamp(); print(d.getFullYear()+"-"+(d.getMonth()+1)+"-"+d.getDate() + " " + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds()) })

If that last one-liner confuses you I have a walkthrough on how that works here: https://stackoverflow.com/a/27613766/445131

I think the DocumentCompleted event will get fired for all child documents that are loaded as well (like JS and CSS, for example). You could look at the WebBrowserDocumentCompletedEventArgs in DocumentCompleted and check the Url property and compare that to the Url of the main page.

Just make a comparison function/functor:

bool my_cmp(const data& a, const data& b)
{
    // smallest comes first
    return a.word.size() < b.word.size();
}

std::sort(info.begin(), info.end(), my_cmp);

Or provide an bool operator<(const data& a) const in your data class:

struct data {
    string word;
    int number;

    bool operator<(const data& a) const
    {
        return word.size() < a.word.size();
    }
};

or non-member as Fred said:

struct data {
    string word;
    int number;
};

bool operator<(const data& a, const data& b)
{
    return a.word.size() < b.word.size();
}

and just call std::sort():

std::sort(info.begin(), info.end());

VARCHAR(MAX) is big enough to accommodate TEXT field. TEXT, NTEXT and IMAGE data types of SQL Server 2000 will be deprecated in future version of SQL Server, SQL Server 2005 provides backward compatibility to data types but it is recommended to use new data types which are VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX).

Either you can expose sanitizer to the view, or expose a method that forwards the call to bypassSecurityTrustUrl

<img class='photo-img' [hidden]="!showPhoto1" 
    [src]='sanitizer.bypassSecurityTrustUrl(theMediaItem.photoURL1)'>

Define "remove".

Arrays are fixed length and can not be resized once created. You can set an element to null to remove an object reference;

for (int i = 0; i < myStringArray.length(); i++)
{
    if (myStringArray[i].equals(stringToRemove))
    {
        myStringArray[i] = null;
        break;
    }
}

or

myStringArray[indexOfStringToRemove] = null;

If you want a dynamically sized array where the object is actually removed and the list (array) size is adjusted accordingly, use an ArrayList<String>

myArrayList.remove(stringToRemove); 

or

myArrayList.remove(indexOfStringToRemove);

Edit in response to OP's edit to his question and comment below

String r = myArrayList.get(rgenerator.nextInt(myArrayList.size()));

from r cookbook, where bp is your ggplot:

Remove legend for a particular aesthetic (fill):

bp + guides(fill=FALSE)

It can also be done when specifying the scale:

bp + scale_fill_discrete(guide=FALSE)

This removes all legends:

bp + theme(legend.position="none")

I'd try adding a keypress Event handler upon keydown. E.g:

window.onkeydown = function() {
    // evaluate key and call respective handler
    window.onkeypress = function() {
       // evaluate key and call respective handler
    }
}

window.onkeyup = function() {
    window.onkeypress = void(0) ;
}

This is just meant to illustrate a pattern; I won't go into detail here (especially not into browser specific level2+ Event registration).

Post back please whether this helps or not.

You need to use -I with each directory. But you can still delimit the directories with whitespace if you use (GNU) make's foreach:

INC=$(DIR1) $(DIR2) ...
INC_PARAMS=$(foreach d, $(INC), -I$d)

You can use following SQL to restore if you've already created database

RESTORE DATABASE [YourDB]
FROM DISK = 'C:\YourDB.bak'
WITH MOVE 'YourDB' TO 'C:\YourDB.mdf',
MOVE 'YourDB_Log' TO 'C:\YourDB.ldf', REPLACE

If you're willing to give up a hint of abstraction, then you could use a custom wrapper class which simply passes everything through to the PDO. Say, something like this: (Warning, code untested)

class SQLitePDOWrapper
{
    private $pdo;

    public function __construct( $dns, $uname = null, $pwd = null, $opts = null )
    {
        $this->pdo = new PDO( $dns, $unam, $pwd, $opts ); 
    }
    public function __call( $nm, $args )
    {
        $ret = call_user_func_array( array( $this->pdo, $nm ), $args );
        if( $ret instanceof PDOStatement )
        {
            return new StatementWrapper( $this, $ret, $args[ 0 ] ); 
               // I'm pretty sure args[ 0 ] will always be your query, 
               // even when binding
        }

        return $ret;
    }

}

class StatementWrapper
{
    private $pdo; private $stat; private $query;

    public function __construct( PDO $pdo, PDOStatement $stat, $query )
    {
        $this->pdo  = $pdo;
        $this->stat = $stat;
        this->query = $query;
    }

    public function rowCount()
    {
        if( strtolower( substr( $this->query, 0, 6 ) ) == 'select' )
        {
            // replace the select columns with a simple 'count(*)
            $res = $this->pdo->query( 
                     'SELECT COUNT(*)' . 
                          substr( $this->query, 
                              strpos( strtolower( $this->query ), 'from' ) ) 
                   )->fetch( PDO::FETCH_NUM );
            return $res[ 0 ];
        }
        return $this->stat->rowCount();
    }

    public function __call( $nm, $args )
    {
        return call_user_func_array( array( $this->stat, $nm ), $args );
    }
}

use numpy

import numpy
zarray = numpy.zeros(100)

And then use the Histogram library function

Try

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

If you want to create and copy the content in a single shot, just use the SELECT:

CREATE TABLE new_tbl SELECT * FROM orig_tbl;

cannot be accessed with an instance reference

It means you're calling a STATIC method and passing it an instance. The easiest solution is to remove Static, eg:

public static void ExportToExcel(IEnumerable data, string sheetName) {

For the listed three conditions only, these expressions might work also:

^\d{5}[-\s]?(?:\d{4})?$
^\[0-9]{5}[-\s]?(?:[0-9]{4})?$
^\[0-9]{5}[-\s]?(?:\d{4})?$
^\d{5}[-\s]?(?:[0-9]{4})?$

Please see this demo for additional explanation.

If we would have had unexpected additional spaces in between 5 and 4 digits or a continuous 9 digits zip code, such as:

123451234
12345 1234
12345  1234

this expression for instance would be a secondary option with less constraints:

^\d{5}([-]|\s*)?(\d{4})?$

Please see this demo for additional explanation.

If you are using Razor view engine then edit the _Layout.cshtml file. Move the @Scripts.Render("~/bundles/jquery") present in footer to the header section and write the javascript / jquery code as you want:

@Scripts.Render("~/bundles/jquery")
<script type="text/javascript">
    $(document).ready(function () {
        var divLength = $('div').length;
        alert(divLength);
    });
</script>

The JPanel is actually only a container where you can put different elements in it (even other JPanels). So in your case I would suggest one big JPanel as some sort of main container for your window. That main panel you assign a Layout that suits your needs ( here is an introduction to the layouts).

After you set the layout to your main panel you can add the paint panel and the other JPanels you want (like those with the text in it..).

  JPanel mainPanel = new JPanel();
  mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));

  JPanel paintPanel = new JPanel();
  JPanel textPanel = new JPanel();

  mainPanel.add(paintPanel);
  mainPanel.add(textPanel);

This is just an example that sorts all sub panels vertically (Y-Axis). So if you want some other stuff at the bottom of your mainPanel (maybe some icons or buttons) that should be organized with another layout (like a horizontal layout), just create again a new JPanel as a container for all the other stuff and set setLayout(new BoxLayout(mainPanel, BoxLayout.X_AXIS).

As you will find out, the layouts are quite rigid and it may be difficult to find the best layout for your panels. So don't give up, read the introduction (the link above) and look at the pictures – this is how I do it :)

Or you can just use NetBeans to write your program. There you have a pretty easy visual editor (drag and drop) to create all sorts of Windows and Frames. (only understanding the code afterwards is ... tricky sometimes.)

EDIT

Since there are some many people interested in this question, I wanted to provide a complete example of how to layout a JFrame to make it look like OP wants it to.

The class is called MyFrame and extends swings JFrame

public class MyFrame extends javax.swing.JFrame{

    // these are the components we need.
    private final JSplitPane splitPane;  // split the window in top and bottom
    private final JPanel topPanel;       // container panel for the top
    private final JPanel bottomPanel;    // container panel for the bottom
    private final JScrollPane scrollPane; // makes the text scrollable
    private final JTextArea textArea;     // the text
    private final JPanel inputPanel;      // under the text a container for all the input elements
    private final JTextField textField;   // a textField for the text the user inputs
    private final JButton button;         // and a "send" button

    public MyFrame(){

        // first, lets create the containers:
        // the splitPane devides the window in two components (here: top and bottom)
        // users can then move the devider and decide how much of the top component
        // and how much of the bottom component they want to see.
        splitPane = new JSplitPane();

        topPanel = new JPanel();         // our top component
        bottomPanel = new JPanel();      // our bottom component

        // in our bottom panel we want the text area and the input components
        scrollPane = new JScrollPane();  // this scrollPane is used to make the text area scrollable
        textArea = new JTextArea();      // this text area will be put inside the scrollPane

        // the input components will be put in a separate panel
        inputPanel = new JPanel();
        textField = new JTextField();    // first the input field where the user can type his text
        button = new JButton("send");    // and a button at the right, to send the text

        // now lets define the default size of our window and its layout:
        setPreferredSize(new Dimension(400, 400));     // let's open the window with a default size of 400x400 pixels
        // the contentPane is the container that holds all our components
        getContentPane().setLayout(new GridLayout());  // the default GridLayout is like a grid with 1 column and 1 row,
        // we only add one element to the window itself
        getContentPane().add(splitPane);               // due to the GridLayout, our splitPane will now fill the whole window

        // let's configure our splitPane:
        splitPane.setOrientation(JSplitPane.VERTICAL_SPLIT);  // we want it to split the window verticaly
        splitPane.setDividerLocation(200);                    // the initial position of the divider is 200 (our window is 400 pixels high)
        splitPane.setTopComponent(topPanel);                  // at the top we want our "topPanel"
        splitPane.setBottomComponent(bottomPanel);            // and at the bottom we want our "bottomPanel"

        // our topPanel doesn't need anymore for this example. Whatever you want it to contain, you can add it here
        bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.Y_AXIS)); // BoxLayout.Y_AXIS will arrange the content vertically

        bottomPanel.add(scrollPane);                // first we add the scrollPane to the bottomPanel, so it is at the top
        scrollPane.setViewportView(textArea);       // the scrollPane should make the textArea scrollable, so we define the viewport
        bottomPanel.add(inputPanel);                // then we add the inputPanel to the bottomPanel, so it under the scrollPane / textArea

        // let's set the maximum size of the inputPanel, so it doesn't get too big when the user resizes the window
        inputPanel.setMaximumSize(new Dimension(Integer.MAX_VALUE, 75));     // we set the max height to 75 and the max width to (almost) unlimited
        inputPanel.setLayout(new BoxLayout(inputPanel, BoxLayout.X_AXIS));   // X_Axis will arrange the content horizontally

        inputPanel.add(textField);        // left will be the textField
        inputPanel.add(button);           // and right the "send" button

        pack();   // calling pack() at the end, will ensure that every layout and size we just defined gets applied before the stuff becomes visible
    }

    public static void main(String args[]){
        EventQueue.invokeLater(new Runnable(){
            @Override
            public void run(){
                new MyFrame().setVisible(true);
            }
        });
    }
}

Please be aware that this is only an example and there are multiple approaches to layout a window. It all depends on your needs and if you want the content to be resizable / responsive. Another really good approach would be the GridBagLayout which can handle quite complex layouting, but which is also quite complex to learn.

use this,
[self score]; 
instead of @selector(score).

In our case, the wrong version of the Sysdeo Tomcat plugin for Eclipse 3.5 was being used. The fix:

• Use tomcatPluginV33 instead of tomcatPluginV321 (extract to C:\eclipse\dropins)
• Ensure that DevloaderTomcat7.jar was placed in the tomcat lib folder
• In Window > Preferences > Tomcat, set the Tomcat version to 7.x

This problem may have been unique to our environment; but, I'll record it here anyway, for posterity's sake.

Assume, you have installed the latest gradle once. But, If your particular project gradle version not match with the gradle version that already installed in the machine, the gradle sycn want to download that version. To prevent this download there is one trick. First You have to know the gradle version that already installed in your machine. Go to : C:\Users{username}.gradle\wrapper\dists, here you see the versions allready installed, remember the latest version, assume it is gradle-6.1.1-all.zip . Now, come back to Android Studio. In your Opened project, navigate Android Studio's project tree, open the file gradle/wrapper/gradle-wrapper.properties. Change this entry:

distributionUrl=http\://services.gradle.org/distributions/gradle-6.1.1-all.zip

This way we prevent downloading the gradle again and again. But avoid this thing, if the version really old. If that, you will find this warning :

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.1.1/userguide/command_line_interface.html#sec:command_line_warnings

'\0' is the way to go. It's a character, which is what's wanted in a string and has the null value.

When we say null terminated string in C/C++, it really means 'zero terminated string'. The NULL macro isn't intended for use in terminating strings.

I got both errors: mostly reading initial communication packet and reading authorization packet one time. It seems random, but sometimes I was able to establish a connection after reboots, but after some time the error creeped back.

Avoiding the 5GHz WiFi in the client seems to have fixed the issue. That's what worked for me (server was always connected to 2.4GHz).

I tried everything from server versions, odbc connector versions, firewall settings, installing some windows update (and then uninstalling them), some of the answers posted here, etc... lost my entire sleep time for today. Super tired day awaits me.

If each item in the list is a string (and any strings inside those strings use " " rather than ' '), you can use regular expressions (re module)

>>> flattener = re.compile("\'.*?\'")
>>> flattener
<_sre.SRE_Pattern object at 0x10d439ca8>
>>> stred = str(in_list)
>>> outed = flattener.findall(stred)

The above code converts in_list into a string, uses the regex to find all the substrings within quotes (i.e. each item of the list) and spits them out as a list.

You are probably connecting fine but don't have sufficient privileges to run show dbs.

You don't need to run the db.auth if you pass the auth in the command line:

mongo somewhere.mongolayer.com:10011/my_database -u username -p password

Once you connect are you able to see collections?

> show collections

If so all is well and you just don't have admin privileges to the database and can't run the show dbs

For linebreaks, PHP as "\n" (see double quote strings) and PHP_EOL.

Here, you are using <br />, which is not a PHP line-break : it's an HTML linebreak.

Here, you can simplify what you posted (with HTML linebreaks) : no need for the strings concatenations : you can put everything in just one string, like this :

$var = "Hi there<br/>Welcome to my website<br/>";

Or, using PHP linebreaks :

$var = "Hi there\nWelcome to my website\n";

Note : you might also want to take a look at the nl2br() function, which inserts <br> before \n.

You have it almost done. Just explicitly say where to create the file

@echo off
  echo.>"d:\testing\dblank.txt"

This creates a file containing a blank line (CR + LF = 2 bytes).

If you want the file empty (0 bytes)

@echo off
  break>"d:\testing\dblank.txt"

You don't. strings.xml is just here to define the raw text messages. You should (must) use styles.xml to define reusable visual styles to apply to your widgets.

Think of it as a good practice to separate the concerns. You can work on the visual styles independently from the text messages.

To count numbers or dates that meet a single test (such as equal to, greater than, less than, greater than or equal to, or less than or equal to), use the COUNTIF function. In Excel 2007 and later, to count numbers or dates that fall within a range (such as greater than 9000 and at the same time less than 22500), you can use the COUNTIFS function. If you are using Excel 2003 or earlier, you can use the SUMPRODUCT function to count the numbers that fall within a range (COUNTIFS was introduced in Excel 2007).

All of them are good in their own ways - They're simply different approaches to the same problems.

In a purely procedural style, data tends to be highly decoupled from the functions that operate on it.

In an object oriented style, data tends to carry with it a collection of functions.

In a functional style, data and functions tend toward having more in common with each other (as in Lisp and Scheme) while offering more flexibility in terms of how functions are actually used. Algorithms tend also to be defined in terms of recursion and composition rather than loops and iteration.

Of course, the language itself only influences which style is preferred. Even in a pure-functional language like Haskell, you can write in a procedural style (though that is highly discouraged), and even in a procedural language like C, you can program in an object-oriented style (such as in the GTK+ and EFL APIs).

To be clear, the "advantage" of each paradigm is simply in the modeling of your algorithms and data structures. If, for example, your algorithm involves lists and trees, a functional algorithm may be the most sensible. Or, if, for example, your data is highly structured, it may make more sense to compose it as objects if that is the native paradigm of your language - or, it could just as easily be written as a functional abstraction of monads, which is the native paradigm of languages like Haskell or ML.

The choice of which you use is simply what makes more sense for your project and the abstractions your language supports.

This also works, and doesn't require a /path/to/file URI conversion. If the file is on the classpath, this will find it.

File currFile = new File(getClass().getClassLoader().getResource("the_file.txt").getFile());

str.matches(regex) behaves like Pattern.matches(regex, str) which attempts to match the entire input sequence against the pattern and returns

true if, and only if, the entire input sequence matches this matcher's pattern

Whereas matcher.find() attempts to find the next subsequence of the input sequence that matches the pattern and returns

true if, and only if, a subsequence of the input sequence matches this matcher's pattern

Thus the problem is with the regex. Try the following.

String test = "User Comments: This is \t a\ta \ntest\n\n message \n";

String pattern1 = "User Comments: [\\s\\S]*^test$[\\s\\S]*";
Pattern p = Pattern.compile(pattern1, Pattern.MULTILINE);
System.out.println(p.matcher(test).find());  //true

String pattern2 = "(?m)User Comments: [\\s\\S]*^test$[\\s\\S]*";
System.out.println(test.matches(pattern2));  //true

Thus in short, the (\\W)*(\\S)* portion in your first regex matches an empty string as * means zero or more occurrences and the real matched string is User Comments: and not the whole string as you'd expect. The second one fails as it tries to match the whole string but it can't as \\W matches a non word character, ie [^a-zA-Z0-9_] and the first character is T, a word character.

Here is an example using openssl_encrypt

//Encryption:
$textToEncrypt = "My Text to Encrypt";
$encryptionMethod = "AES-256-CBC";
$secretHash = "encryptionhash";
$iv = mcrypt_create_iv(16, MCRYPT_RAND);
$encryptedText = openssl_encrypt($textToEncrypt,$encryptionMethod,$secretHash, 0, $iv);

//Decryption:
$decryptedText = openssl_decrypt($encryptedText, $encryptionMethod, $secretHash, 0, $iv);
print "My Decrypted Text: ". $decryptedText;

How about this?

(A=1 OR B=1 OR C=1) 
AND NOT (A=1 AND B=1 AND C=1)

And if A, B and C can have null values you would need the following:

(A=1 OR B=1 OR C=1) 
AND NOT ( (A=1 AND A is not null) AND (B=1 AND B is not null) AND (C=1 AND C is not null) )

This is scalable to larger number of fields and hence more applicable.

For that, you can use default difflib in python

from difflib import SequenceMatcher

def similar(a, b):
    return SequenceMatcher(None, a, b).ratio()

then call similar() as

similar(string1, string2)

it will return compare as ,ratio >= threshold to get match result

I had this issue when I was nesting promises. A promise inside of a promise would return 200 to the server, but then the outer promise's catch statement would return a 500. Once I fixed this, the problem went away.

Adding to Cheeken's answer, This is how you sort a list of tuples by the 2nd item in descending order.

sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)],key=lambda x: x[1], reverse=True)

Another option that may be suitable in this situation is using XML

The XML option to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation. 

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

Vertical expansion

Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

Horizontal expansion

Unlike the PIVOT, newly added documents can be displayed without altering the script.

Performance breakdown

In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

the first case can also be easily done as:

A=A[0]

NameValueCollection nvclc = Request.Form;
string   uName= nvclc ["txtUserName"];
string   pswod= nvclc ["txtPassword"];
//try login
CheckLogin(uName, pswod);

There are a few ways depending on some data rules that you have not included, but here is one way using what you gave.

SELECT
    t1.Field1,
    t2.Field2
FROM Table1 t1
    LEFT JOIN Table1 t2 ON t1.FK = t2.FK AND t2.Field1 IS NULL

Another way:

SELECT
    t1.Field1,
    (SELECT Field2 FROM Table2 t2 WHERE t2.FK = t1.FK AND Field1 IS NULL) AS Field2
FROM Table1 t1

batchfiles perform simple string substitution with variables. so, a simple

goto :language%language%
echo notfound
...

does this without any need for if.

You can use:

ptx.[tablename].Select( o => true)

class Program
{
    static void Main(string[] args)
    {
        String unicodeString =
        "This Unicode string contains two characters " +
        "with codes outside the traditional ASCII code range, " +
        "Pi (\u03a0) and Sigma (\u03a3).";

        Console.WriteLine("Original string:");
        Console.WriteLine(unicodeString);
        UnicodeEncoding unicodeEncoding = new UnicodeEncoding();
        byte[] utf16Bytes = unicodeEncoding.GetBytes(unicodeString);
        char[] chars = unicodeEncoding.GetChars(utf16Bytes, 2, utf16Bytes.Length - 2);
        string s = new string(chars);
        Console.WriteLine();
        Console.WriteLine("Char Array:");
        foreach (char c in chars) Console.Write(c);
        Console.WriteLine();
        Console.WriteLine();
        Console.WriteLine("String from Char Array:");
        Console.WriteLine(s);

        Console.ReadKey();
    }
}

You used Fruits.shift() method to first element remove . Fruits.pop() method used for last element remove one by one if you used button click. Fruits.slice( start position, delete element)You also used slice method for remove element in middle start.

Fisher-Yates shuffle in javascript. I'm posting this here because the use of two utility functions (swap and randInt) clarifies the algorithm compared to the other answers here.

function swap(arr, i, j) { 
  // swaps two elements of an array in place
  var temp = arr[i];
  arr[i] = arr[j];
  arr[j] = temp;
}
function randInt(max) { 
  // returns random integer between 0 and max-1 inclusive.
  return Math.floor(Math.random()*max);
}
function shuffle(arr) {
  // For each slot in the array (starting at the end), 
  // pick an element randomly from the unplaced elements and
  // place it in the slot, exchanging places with the 
  // element in the slot. 
  for(var slot = arr.length - 1; slot > 0; slot--){
    var element = randInt(slot+1);
    swap(arr, element, slot);
  }
}

A edited version of @jfriend000 version:

    /**
     * Generates a random string
     * 
     * @param int length_
     * @return string
     */
    function randomString(length_) {

        var chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghiklmnopqrstuvwxyz'.split('');
        if (typeof length_ !== "number") {
            length_ = Math.floor(Math.random() * chars.length_);
        }
        var str = '';
        for (var i = 0; i < length_; i++) {
            str += chars[Math.floor(Math.random() * chars.length)];
        }
        return str;
    }

Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).

With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.

We'll take an example, a company table with a user table containing people from theses company

CREATE TABLE COMPANY (
     company_id INT NOT NULL,
     company_name VARCHAR(50),
     PRIMARY KEY (company_id)
) ENGINE=INNODB;

CREATE TABLE USER (
     user_id INT, 
     user_name VARCHAR(50), 
     company_id INT,
     INDEX company_id_idx (company_id),
     FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;

Let's look at the ON UPDATE clause:

• ON UPDATE RESTRICT : the default : if you try to update a company_id in table COMPANY the engine will reject the operation if one USER at least links on this company.
• ON UPDATE NO ACTION : same as RESTRICT.
• ON UPDATE CASCADE : the best one usually : if you update a company_id in a row of table COMPANY the engine will update it accordingly on all USER rows referencing this COMPANY (but no triggers activated on USER table, warning). The engine will track the changes for you, it's good.
• ON UPDATE SET NULL : if you update a company_id in a row of table COMPANY the engine will set related USERs company_id to NULL (should be available in USER company_id field). I cannot see any interesting thing to do with that on an update, but I may be wrong.

And now on the ON DELETE side:

• ON DELETE RESTRICT : the default : if you try to delete a company_id Id in table COMPANY the engine will reject the operation if one USER at least links on this company, can save your life.
• ON DELETE NO ACTION : same as RESTRICT
• ON DELETE CASCADE : dangerous : if you delete a company row in table COMPANY the engine will delete as well the related USERs. This is dangerous but can be used to make automatic cleanups on secondary tables (so it can be something you want, but quite certainly not for a COMPANY<->USER example)
• ON DELETE SET NULL : handful : if you delete a COMPANY row the related USERs will automatically have the relationship to NULL. If Null is your value for users with no company this can be a good behavior, for example maybe you need to keep the users in your application, as authors of some content, but removing the company is not a problem for you.

usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.

Edit

It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.

• http://dev.mysql.com/doc/refman/5.6/en/triggers.html

MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server

• http://dev.mysql.com/doc/refman/5.6/en/stored-program-restrictions.html#stored-routines-trigger-restrictions

==> See below the last edit, things are moving on this domain

Triggers are not activated by foreign key actions.

And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.

But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.

12/2017-Updating this Edit about MySQL:

as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).

Also if you use SymPy you can use sympy.oo

>>> from sympy import oo
>>> oo + 1
oo
>>> oo - oo
nan

etc.

you can use the collector like this

  Stream<String> io = Stream.of("foo" , "lan" , "mql");
  io.collect(Collectors.toCollection(ArrayList<String>::new));

Sqlite helper class helps us to manage database creation and version management. SQLiteOpenHelper takes care of all database management activities. To use it,
1.Override onCreate(), onUpgrade() methods of SQLiteOpenHelper. Optionally override onOpen() method.
2.Use this subclass to create either a readable or writable database and use the SQLiteDatabase's four API methods insert(), execSQL(), update(), delete() to create, read, update and delete rows of your table.

Example to create a MyEmployees table and to select and insert records:

public class MyDatabaseHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "DBName";

    private static final int DATABASE_VERSION = 2;

    // Database creation sql statement
    private static final String DATABASE_CREATE = "create table MyEmployees
                                 ( _id integer primary key,name text not null);";

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Method is called during creation of the database
    @Override
    public void onCreate(SQLiteDatabase database) {
        database.execSQL(DATABASE_CREATE);
    }

    // Method is called during an upgrade of the database,
    @Override
    public void onUpgrade(SQLiteDatabase database,int oldVersion,int newVersion){
        Log.w(MyDatabaseHelper.class.getName(),
                         "Upgrading database from version " + oldVersion + " to "
                         + newVersion + ", which will destroy all old data");
        database.execSQL("DROP TABLE IF EXISTS MyEmployees");
        onCreate(database);
    }
}

Now you can use this class as below,

public class MyDB{  

    private MyDatabaseHelper dbHelper;  

    private SQLiteDatabase database;  

    public final static String EMP_TABLE="MyEmployees"; // name of table 

    public final static String EMP_ID="_id"; // id value for employee
    public final static String EMP_NAME="name";  // name of employee

    /** 
     * 
     * @param context 
     */  
    public MyDB(Context context){  
        dbHelper = new MyDatabaseHelper(context);  
        database = dbHelper.getWritableDatabase();  
    }


    public long createRecords(String id, String name){  
        ContentValues values = new ContentValues();  
        values.put(EMP_ID, id);  
        values.put(EMP_NAME, name);  
        return database.insert(EMP_TABLE, null, values);  
    }    

    public Cursor selectRecords() {
        String[] cols = new String[] {EMP_ID, EMP_NAME};  
        Cursor mCursor = database.query(true, EMP_TABLE,cols,null  
            , null, null, null, null, null);  
        if (mCursor != null) {  
            mCursor.moveToFirst();  
        }  
        return mCursor; // iterate to get each value.
    }
}

Now you can use MyDB class in you activity to have all the database operations. The create records will help you to insert the values similarly you can have your own functions for update and delete.

If you want to append to the lists of each key inside a dictionary, you can append new values to them using + operator (tested in Python 3.7):

mydict = {'a':[], 'b':[]}
print(mydict)
mydict['a'] += [1,3]
mydict['b'] += [4,6]
print(mydict)
mydict['a'] += [2,8]
print(mydict)

and the output:

{'a': [], 'b': []}
{'a': [1, 3], 'b': [4, 6]}
{'a': [1, 3, 2, 8], 'b': [4, 6]}

mydict['a'].extend([1,3]) will do the job same as + without creating a new list (efficient way).

You could try this:

DECLARE @List VARCHAR(MAX)

SELECT @List = '1,2,3,4,5,6,7,8'

EXEC(
'DELETE
FROM TABLE
WHERE ID NOT IN (' + @List + ')'
)

encodeURIComponent(JSON.stringify(object_to_be_serialised))

Because by default jQuery serializes objects passed as the data parameter to $.ajax. It uses $.param to convert the data to a query string.

From the jQuery docs for $.ajax:

[the data argument] is converted to a query string, if not already a string

If you want to send JSON, you'll have to encode it yourself:

data: JSON.stringify(arr);

Note that JSON.stringify is only present in modern browsers. For legacy support, look into json2.js

template<class T>
auto optionalToString(T* obj)
->decltype( obj->toString(), std::string() )
{
     return obj->toString();
}

template<class T>
auto optionalToString(T* obj)
->decltype( std::string() )
{
     throw "Error!";
}

I believe this error message is due to a "zombie transaction".

Look for possible areas where the transacton is being committed twice (or rolled back twice, or rolled back and committed, etc.). Does the .Net code commit the transaction after the SP has already committed it? Does the .Net code roll it back on encountering an error, then attempt to roll it back again in a catch (or finally) clause?

It's possible an error condition was never being hit on the old server, and thus the faulty "double rollback" code was never hit. Maybe now you have a situation where there is some configuration error on the new server, and now the faulty code is getting hit via exception handling.

Can you debug into the error code? Do you have a stack trace?

Not only double quotes, you will be in need for single quote ('), double quote ("), backslash (\) and NUL (the NULL byte).

Use fputcsv() to write, and fgetcsv() to read, which will take care of all.

I use this approach, since you don't need to constantly reset the time when an event fires, instead we just record the time, this generates the idle start point.

           function idle(WAIT_FOR_MINS, cb_isIdle) {
            var self = this, 
                idle,
                ms = (WAIT_FOR_MINS || 1) * 60000,
                lastDigest = new Date(),
                watch;
            //document.onmousemove = digest;
            document.onkeypress = digest;
            document.onclick = digest;

            function digest() {
               lastDigest = new Date(); 
            }
            // 1000 milisec = 1 sec
            watch = setInterval(function(){
                if (new Date() - lastDigest > ms && cb_isIdel) {
                    clearInterval(watch);
                    cb_isIdle();
                }

            }, 1000*60);    
        },

1. Highlight the range in question.
2. On the Home tab, in the Styles Group, Click "Conditional Formatting".
3. Click "Highlight cell rules"

For the first rule,

Click "greater than", then in the value option box, click on the cell criteria you want it to be less than, than use the format drop-down to select your color.

For the second,

Click "less than", then in the value option box, type "=.9*" and then click the cell criteria, then use the formatting just like step 1.

For the third,

Same as the second, except your formula is =".8*" rather than .9.

With a foreach:

let itemYouWant = null;
array.forEach((item) => {
    if (item.name === 'string 1') {
        itemYouWant = item;
    }
});
console.log(itemYouWant);

CSS table display is ideal for this:

.parent {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
}_x000D_
.parent > div {_x000D_
  display: table-cell;_x000D_
}_x000D_
.child-left {_x000D_
  background: powderblue;_x000D_
}_x000D_
.child-right {_x000D_
  background: papayawhip;_x000D_
}

<div class="parent">_x000D_
  <div class="child-left">Short</div>_x000D_
  <div class="child-right">Tall<br>Tall</div>_x000D_
</div>

Original answer (assumed any column could be taller):

You're trying to make the parent's height dependent on the children's height and children's height dependent on parent's height. Won't compute. CSS Faux columns is the best solution. There's more than one way of doing that. I'd rather not use JavaScript.

//Runs function after x seconds

public static func runThisAfterDelay(seconds: Double, after: @escaping () -> Void) {
    runThisAfterDelay(seconds: seconds, queue: DispatchQueue.main, after: after)
}

public static func runThisAfterDelay(seconds: Double, queue: DispatchQueue, after: @escaping () -> Void) {
    let time = DispatchTime.now() + Double(Int64(seconds * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)
    queue.asyncAfter(deadline: time, execute: after)
}

//Use:-

runThisAfterDelay(seconds: x){
  //write your code here
}

Just adding

left:15%; 

into my css menu of

#menu li {
float: left;
position:relative;
left: 15%;
list-style:none;
}

did the centering trick too

My column names is as below

colnames(t)
[1] "Class"    "Sex"      "Age"      "Survived" "Freq" 

I want to change column name of Class and Sex

colnames(t)=c("STD","Gender","AGE","SURVIVED","FREQ")

What about creating an Extension Method like this....

 public static string ReplaceTHAT(this string s)
 {
    return s.Replace("\n\r", "");
 }

And then when you want to replace that wherever you want you can do this.

s.ReplaceTHAT();

Best Regards!

In nutshell,

@Pathparam works for value passing through both Resources and Query String

• /user/1
• /user?id=1

@Queryparam works for value passing only Query String

• /user?id=1

In my Impression, the GDI approach and the DX approach are different in its nature. painting using GDI applies the FLUSH method, the FLUSH approach draws the frame then clear it and redraw another frame in the same buffer, this will result in flickering in games require high frame rate.

1. WHY DX quicker? in DX (or graphics world), a more mature method called double buffer rendering is applied, where two buffers are present, when present the front buffer to the hardware, you can render to the other buffer as well, then after the frame 1 is finished rendering, the system swap to the other buffer( locking it for presenting to hardware , and release the previous buffer ), in this way the rendering inefficiency is greatly improved.
2. WHY turning down hardware acceleration quicker? although with double buffer rendering, the FPS is improved, but the time for rendering is still limited. modern graphic hardware usually involves a lot of optimization during rendering typically like anti-aliasing, this is very computation intensive, if you don't require that high quality graphics, of course you can just disable this option. and this will save you some time.

I think what you really need is a replay system, which I totally agree with what people discussed.

I came across a similar question when dealing with an API that accepts both XML and JSON, but doesn't document how it would handle what you'd expect to be duplicate keys in the JSON accepted.

The following is a valid XML representation of your sample JSON:

<object>
  <a>x</a>
  <a>y</a>
</object>

When this is converted into JSON, you get the following:

{
  "object": {
    "a": [
      "x",
      "y"
    ]
  }
}

A natural mapping from a language that handles what you might call duplicate keys to another, can serve as a potential best practice reference here.

Hope that helps someone!

From the doc for path.resolve:

The resulting path is normalized and trailing slashes are removed unless the path is resolved to the root directory.

But path.join keeps trailing slashes

So

__dirname = '/';
path.resolve(__dirname, 'foo/'); // '/foo'
path.join(__dirname, 'foo/'); // '/foo/'

For me, I usually use DataContext together in order to bind two-depth property such as this question.

<TextBlock DataContext="{Binding SelectedRule}" Text="{Binding Name}" />

Or, I prefer to use ElementName because it achieves bindings only with view controls.

<TextBlock DataContext="{Binding ElementName=lbRules, Path=SelectedItem}" Text="{Binding Name}" />

I had a similar issue. the error comes up when the i switched the fb user from setting. Facebook authorization fails on iOS6 when switching FB account on device This solved my problem

I managed to solve mine, by changing

add_executable(file1.cpp)

to

add_executable(ProjectName file1.cpp)

How about you just write you own? The core of the PE architecture hasn't been seriously changed since its implementation in Windows 95. Here's a C# example:

    public static ushort GetPEArchitecture(string pFilePath)
    {
        ushort architecture = 0;
        try
        {
            using (System.IO.FileStream fStream = new System.IO.FileStream(pFilePath, System.IO.FileMode.Open, System.IO.FileAccess.Read))
            {
                using (System.IO.BinaryReader bReader = new System.IO.BinaryReader(fStream))
                {
                    if (bReader.ReadUInt16() == 23117) //check the MZ signature
                    {
                        fStream.Seek(0x3A, System.IO.SeekOrigin.Current); //seek to e_lfanew.
                        fStream.Seek(bReader.ReadUInt32(), System.IO.SeekOrigin.Begin); //seek to the start of the NT header.
                        if (bReader.ReadUInt32() == 17744) //check the PE\0\0 signature.
                        {
                            fStream.Seek(20, System.IO.SeekOrigin.Current); //seek past the file header,
                            architecture = bReader.ReadUInt16(); //read the magic number of the optional header.
                        }
                    }
                }
            }
        }
        catch (Exception) { /* TODO: Any exception handling you want to do, personally I just take 0 as a sign of failure */}
        //if architecture returns 0, there has been an error.
        return architecture;
    }
}

Now the current constants are:

0x10B - PE32  format.
0x20B - PE32+ format.

But with this method it allows for the possibilities of new constants, just validate the return as you see fit.

My approach to delete all rows from a table i DynamoDb is just to pull all rows out from the table, using DynamoDbs ScanAsync and then feed the result list to DynamoDbs AddDeleteItems. Below code in C# works fine for me.

        public async Task DeleteAllReadModelEntitiesInTable()
    {
        List<ReadModelEntity> readModels;

        var conditions = new List<ScanCondition>();
        readModels = await _context.ScanAsync<ReadModelEntity>(conditions).GetRemainingAsync();

        var batchWork = _context.CreateBatchWrite<ReadModelEntity>();
        batchWork.AddDeleteItems(readModels);
        await batchWork.ExecuteAsync();
    }

Note: Deleting the table and then recreating it again from the web console may cause problems if using YAML/CloudFormation to create the table.

simple activity controller class !!!

class ActivityIndicator: UIVisualEffectView {


let activityIndictor: UIActivityIndicatorView = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.WhiteLarge)
let label: UILabel = UILabel()
let blurEffect = UIBlurEffect(style: .Dark)
let vibrancyView: UIVisualEffectView

init() {

    self.vibrancyView = UIVisualEffectView(effect: UIVibrancyEffect(forBlurEffect: blurEffect))
    super.init(effect: blurEffect)
    self.setup()
}

required init?(coder aDecoder: NSCoder) {

    self.vibrancyView = UIVisualEffectView(effect: UIVibrancyEffect(forBlurEffect: blurEffect))
    super.init(coder: aDecoder)
    self.setup()
}

func setup() {

    contentView.addSubview(vibrancyView)
    vibrancyView.contentView.addSubview(activityIndictor)
    activityIndictor.startAnimating()
}

override func didMoveToSuperview() {
    super.didMoveToSuperview()

    if let superview = self.superview {
        let width: CGFloat = 75.0
        let height: CGFloat = 75.0
        self.frame = CGRectMake(superview.frame.size.width / 2 - width / 2,
                                superview.frame.height / 2 - height / 2,
                                width,
                                height)
        vibrancyView.frame = self.bounds
        let activityIndicatorSize: CGFloat = 40
        activityIndictor.frame = CGRectMake(18, height / 2 - activityIndicatorSize / 2,
                                            activityIndicatorSize,
                                            activityIndicatorSize)
        layer.cornerRadius = 8.0
        layer.masksToBounds = true

    }
}

func show() {
    self.hidden = false
}

func hide() {
    self.hidden = true
}}

usage :-

let activityIndicator = ActivityIndicator()
    self.view.addSubview(activityIndicator)

to hide :-

activityIndicator.hide()

For a simple two- (or one) liner this code can be:

checkboxes = document.getElementsByName("NameOfCheckboxes");
selectedCboxes = Array.prototype.slice.call(checkboxes).filter(ch => ch.checked==true);

Here the Array.prototype.slice.call() part converts the object NodeList of all the checkboxes holding that name ("NameOfCheckboxes") into a new array, on which you then use the filter method. You can then also, for example, extract the values of the checkboxes by adding a .map(ch => ch.value) on the end of line 2. The => is javascript's arrow function notation.

Use the below snippet it will be helpfull.

OleDbCommand POCcommand = new OleDbCommand();

OleDbDataAdapter POCCommand = new OleDbDataAdapter("select * from [Sheet1$] ", POCcon);

Register a hook to unsubscribe your listeners when the component is removed:

to your .footer

just do it

Do you use https links instead of ssh links? Because the https link is limited by the size of the upload of HttpServer (such as Apache, Ngnix), there is no such restriction when using ssh.

Use the following method to switch to the ssh link.

1. Open terminal.
2. Switch to your project's working directory.
3. Get the name of the remote repository

$ git remote -v
origin  https://github.com/[user_name]/[project_name].git (fetch)
origin  https://github.com/[user_name]/[project_name].git (push)

4. Modify the git address to ssh link.

git remote set-url origin [email protected]:[user_name]/[project_name].git

If you determine the remote repository name, proceed directly to step 4. Now, you can do the push operation happily.

You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.

If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

cacerts is where Java stores public certificates of root CAs. Java uses cacerts to authenticate the servers.

Keystore is where Java stores the private keys of the clients so that it can share it to the server when the server requests client authentication.

Export the store from the module you called createStore with. Then you are assured it will both be created and will not pollute the global window space.

MyStore.js

const store = createStore(myReducer);
export store;

or

const store = createStore(myReducer);
export default store;

MyClient.js

import {store} from './MyStore'
store.dispatch(...)

or if you used default

import store from './MyStore'
store.dispatch(...)

For Multiple Store Use Cases

If you need multiple instances of a store, export a factory function. I would recommend making it async (returning a promise).

async function getUserStore (userId) {
   // check if user store exists and return or create it.
}
export getUserStore

On the client (in an async block)

import {getUserStore} from './store'

const joeStore = await getUserStore('joe')

I'm updating this thread with a new answer because I've found the solution to my miserable situation after not less than a week ...

For those still experiencing the error even though they have their path value set properly, check your pathext variable to have the value (default value in windows 7 +) : .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

Mine was to set only to : .BAT and changing it solved the problem. I wonder why nobody brought this up ...

Hope this helps!

I started using mocks with EasyMock. Easy enough to understand, but the replay step was kinda annoying. Mockito removes this, also has a cleaner syntax as it looks like readability was one of its primary goals. I cannot stress enough how important this is, since most of developers will spend their time reading and maintaining existing code, not creating it.

Another nice thing is that interfaces and implementation classes are handled in the same way, unlike in EasyMock where still you need to remember (and check) to use an EasyMock Class Extension.

I've taken a quick look at JMockit recently, and while the laundry list of features is pretty comprehensive, I think the price of this is legibility of resulting code, and having to write more.

For me, Mockito hits the sweet spot, being easy to write and read, and dealing with majority of the situations most code will require. Using Mockito with PowerMock would be my choice.

One thing to consider is that the tool you would choose if you were developing by yourself, or in a small tight-knit team, might not be the best to get for a large company with developers of varying skill levels. Readability, ease of use and simplicity would need more consideration in the latter case. No sense in getting the ultimate mocking framework if a lot of people end up not using it or not maintaining the tests.

Most of the solutions on this question all require you to specify the 'page' on both the li and the a (via HtmlHelper) tag. Both @Wolles and @Crush's answers eliminated this duplication, which was nice, but they were using HtmlHelper extension methods instead of TagHelpers. And I wanted to use a TagHelper and support Razor Pages.

You can read my full post here (and get the source code), but the gist of it is:

<bs-menu-link asp-page="/Events/Index" menu-text="Events"></bs-menu-link>

Would render (if the link was active obviously):

<li class="active"><a href="/Events">Events</a></li>

My TagHelper leverages the AnchorTagHelper internally (thus supporting asp-page, asp-controller, asp-action, etc. attributes). The 'checks' for active or not is similar to many of the answers to this post.

The easy and nice answer is using the Extension Method:

static class ExtentionMethodCollection
{
    public static string Inverse(this string @base)
    {
        return new string(@base.Reverse().ToArray());
    }
}

and here's the output:

string Answer = "12345".Inverse(); // = "54321"

SELECT * FROM Member WHERE month(date_created) = month(NOW() - INTERVAL 1 MONTH);

IMO the main difference is that Textbox is not strongly typed. TextboxFor take a lambda as a parameter that tell the helper the with element of the model to use in a typed view.

You can do the same things with both, but you should use typed views and TextboxFor when possible.

SELECT to_char(emp_login_date,'DD-MON-YYYY HH24:MI:SS'),A.* 
FROM emp_log A
WHERE emp_login_date BETWEEN to_date(to_char('21-MAY-2015 11:50:14'),'DD-MON-YYYY HH24:MI:SS')
AND
to_date(to_char('22-MAY-2015 17:56:52'),'DD-MON-YYYY HH24:MI:SS') 
ORDER BY emp_login_date

For Kotlin and bindings the code is:

binding.spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
            override fun onNothingSelected(parent: AdapterView<*>?) {
            }

            override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
            }
        }

Eulerian path must visit each edge exactly once, while Hamiltonian path must visit each vertex exactly once.

This is what apps like quicken, ms money etc use.

Specifying a max-width or fixed width doesn't work for all situations, and the table should be fluid and auto-space its cells. That's what tables are for. Works on IE9 and other browsers.

Use this: http://jsfiddle.net/maruxa1j/

    width: 100%;
}
.first {
    width: 50%;
}
.ellipsis {
    position: relative;
}
.ellipsis:before {
    content: ' ';
    visibility: hidden;
}
.ellipsis span {
    position: absolute;
    left: 0;
    right: 0;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

        <tr>
            <th>Header 1</th>
            <th>Header 2</th>
            <th>Header 3</th>
            <th>Header 4</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td class="ellipsis first"><span>This Text Overflows and is too large for its cell.</span></td>
            <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td>
            <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td>
            <td class="ellipsis"><span>This Text Overflows and is too large for its cell.</span></td>
        </tr>

unset($a->new_property);

This works for array elements, variables, and object attributes.

Example:

$a = new stdClass();

$a->new_property = 'foo';
var_export($a);  // -> stdClass::__set_state(array('new_property' => 'foo'))

unset($a->new_property);
var_export($a);  // -> stdClass::__set_state(array())

The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.

(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)

If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.

this things is worked on laravel 5.1.

first, on your terminal execute this code

php artisan make:migration add_paid_to_users --table=users

after that go to your project directory and expand directory database - migration and edit file add_paid_to_users.php, add this code

public function up()
{
    Schema::table('users', function (Blueprint $table) {
         $table->string('paid'); //just add this line
    });
}

after that go back to your terminal and execute this command

php artisan migrate

hope this help.

There are plenty of situations where it makes a lot of sense to have ListView's in a ScrollView.

Here's code based on DougW's suggestion... works in a fragment, takes less memory.

public static void setListViewHeightBasedOnChildren(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null) {
        return;
    }
    int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
    int totalHeight = 0;
    View view = null;
    for (int i = 0; i < listAdapter.getCount(); i++) {
        view = listAdapter.getView(i, view, listView);
        if (i == 0) {
            view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, LayoutParams.WRAP_CONTENT));
        }
        view.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
        totalHeight += view.getMeasuredHeight();
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();
}

call setListViewHeightBasedOnChildren(listview) on each embedded listview.

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

    public static final int TIME_OUT = 86400 * 1000;

    LinkedHashMap<K, Hit> linkedHashMap = new LinkedHashMap<K, Hit>() {
        @Override
        protected boolean removeEldestEntry(Map.Entry<K, Hit> eldest) {
            final long time = System.currentTimeMillis();
            if( time - eldest.getValue().time > TIME_OUT) {
                Iterator<Hit> i = values().iterator();

                i.next();
                do {
                    i.remove();
                } while( i.hasNext() && time - i.next().time > TIME_OUT );
            }
            return false;
        }
    };


    public boolean putIfNotExists(K key) {
        Hit value = linkedHashMap.get(key);
        if( value != null ) {
            return false;
        }

        linkedHashMap.put(key, new Hit());
        return true;
    }

    private static class Hit {
        final long time;


        Hit() {
            this.time = System.currentTimeMillis();
        }
    }
}

After SqlCommand cmd=new SqlCommand ("insert into time(project,iteration)values('.... Add

cmd.Connection = conn;

Hope this help

String s1=""; // empty string assigned to s1 , s1 has length 0, it holds a value of no length string

String s2=null; // absolutely nothing, it holds no value, you are not assigning any value to s2

so null is not the same as empty.

hope that helps!!!

As an addition to the answer of @mavroprovato, if you want to trust all certificates instead of just self-signed, you'd do (in the style of your code)

builder.loadTrustMaterial(null, new TrustStrategy(){
    public boolean isTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
        return true;
    }
});

or (direct copy-paste from my own code):

import javax.net.ssl.SSLContext;
import org.apache.http.ssl.TrustStrategy;
import org.apache.http.ssl.SSLContexts;

// ...

        SSLContext sslContext = SSLContexts
                .custom()
                //FIXME to contain real trust store
                .loadTrustMaterial(new TrustStrategy() {
                    @Override
                    public boolean isTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                        return true;
                    }
                })
                .build();

And if you want to skip hostname verification as well, you need to set

    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();

as well. (ALLOW_ALL_HOSTNAME_VERIFIER is deprecated).

Obligatory warning: you shouldn't really do this, accepting all certificates is a bad thing. However there are some rare use cases where you want to do this.

As a note to code previously given, you'll want to close response even if httpclient.execute() throws an exception

CloseableHttpResponse response = null;
try {
    response = httpclient.execute(httpGet);
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
}
finally {
    if (response != null) {
        response.close();
    }
}

To reverse an int array, you swap items up until you reach the midpoint, like this:

for(int i = 0; i < validData.length / 2; i++)
{
    int temp = validData[i];
    validData[i] = validData[validData.length - i - 1];
    validData[validData.length - i - 1] = temp;
}

The way you are doing it, you swap each element twice, so the result is the same as the initial list.

Using Blob as a source for an img:

template:

<img [src]="url">

component:

 public url : SafeResourceUrl;

 constructor(private http: HttpClient, private sanitizer: DomSanitizer) {
   this.getImage('/api/image.jpg').subscribe(x => this.url = x)
 }

 public getImage(url: string): Observable<SafeResourceUrl> {
   return this.http
     .get(url, { responseType: 'blob' })
     .pipe(
       map(x => {
         const urlToBlob = window.URL.createObjectURL(x) // get a URL for the blob
         return this.sanitizer.bypassSecurityTrustResourceUrl(urlToBlob); // tell Anuglar to trust this value
       }),
     );
 }

Anyway, here is how to fix it: Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New: Variable name: _JAVA_OPTIONS Variable value: -Xmx512M

OR

Change the ant call as shown as below.

   <exec
        **<arg value="-J-Xmx512m" />**
    </exec>

It worked for me.

At the VS code

press Ctrl+Shift+P

then type Format Document With...

At the end of the list click on Configure Default Formatter...

Now you can choose your favorite beautifier from the list.

Update 2021

if "Format Document With..." didn't exist any more, go to file => preferences => settings then navigate to Extensions => Vetur scroll a little bit then you will see format > defaultFormatter:css, now you can pick any document formatter that you installed bofer for different file type extensions.

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

The only way to add headers to a request from inside a browser is use the XmlHttpRequest setRequestHeader method.

Using this with "GET" request will download the resource. The trick then is to access the resource in the intended way. Ostensibly you should be able to allow the GET response to be cacheable for a short period, hence navigation to a new URL or the creation of an IMG tag with a src url should use the cached response from the previous "GET". However that is quite likely to fail especially in IE which can be a bit of a law unto itself where the cache is concerned.

Ultimately I agree with Mehrdad, use of query string is easiest and most reliable method.

Another quirky alternative is use an XHR to make a request to a URL that indicates your intent to access a resource. It could respond with a session cookie which will be carried by the subsequent request for the image or link.

For ListBox / DropDown in MVC5 - i've found this to work for me sofar:

in Model:

[Required(ErrorMessage = "- Select item -")]
 public List<string> SelectedItem { get; set; }
 public List<SelectListItem> AvailableItemsList { get; set; }

in View:

@Html.ListBoxFor(model => model.SelectedItem, Model.AvailableItemsList)
@Html.ValidationMessageFor(model => model.SelectedItem, "", new { @class = "text-danger" })

You can use 'apply' to run a function or the rows or columns of a matrix or numerical data frame:

cluster1 <- data.frame(a=1:5, b=11:15, c=21:25, d=31:35)

apply(cluster1,2,mean)  # applies function 'mean' to 2nd dimension (columns)

apply(cluster1,1,mean)  # applies function to 1st dimension (rows)

sapply(cluster1, mean)  # also takes mean of columns, treating data frame like list of vectors

Use != or <>. Both stands for not equal.

The comparison operators <> and != are alternate spellings of the same operator. != is the preferred spelling; <> is obsolescent. [Reference: Python language reference]

It is an old question, but still has no answer correct answer, so:

Have you tried jQuery-File-Upload?

Here is an example from the link above that might solve your problem:

$('#fileupload').fileupload({
    add: function (e, data) {
        var that = this;
        $.getJSON('/example/url', function (result) {
            data.formData = result; // e.g. {id: 123}
            $.blueimp.fileupload.prototype
                .options.add.call(that, e, data);
        });
    } 
});

It's declaring the string as nvarchar data type, rather than varchar

You may have seen Transact-SQL code that passes strings around using an N prefix. This denotes that the subsequent string is in Unicode (the N actually stands for National language character set). Which means that you are passing an NCHAR, NVARCHAR or NTEXT value, as opposed to CHAR, VARCHAR or TEXT.

To quote from Microsoft:

Prefix Unicode character string constants with the letter N. Without the N prefix, the string is converted to the default code page of the database. This default code page may not recognize certain characters.

If you want to know the difference between these two data types, see this SO post:

What is the difference between varchar and nvarchar?

It will return 18 results starting on record #9 and finishing on record #26.

Start by reading the query from offset. First you offset by 8, which means you skip the first 8 results of the query. Then you limit by 18. Which means you consider records 9, 10, 11, 12, 13, 14, 15, 16....24, 25, 26 which are a total of 18 records.

Check this out.

And also the official documentation.

I would go for aspect-ratio, it offers way more possibilities.

/* Exact aspect ratio */
@media (aspect-ratio: 2/1) {
    ...
}

/* Minimum aspect ratio */
@media (min-aspect-ratio: 16/9) {
    ...
}

/* Maximum aspect ratio */
@media (max-aspect-ratio: 8/5) {
    ...
}

Both, orientation and aspect-ratio depend on the actual size of the viewport and have nothing todo with the device orientation itself.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

A solution which worked in my case is:
  1. Go to the module having Main class.
  2. Right click on pom.xml under this module.
  3. Select "Run Maven" -> "UpdateSnapshots"

I'm not sure if the previous approaches have stopped working, but in any case, here's another way of removing the warnings:

PYTHONWARNINGS="ignore:Unverified HTTPS request" ./do-insecure-request.py

Basically, adding an environment variable in the context of the script execution.

From the documentation: https://urllib3.readthedocs.org/en/latest/security.html#disabling-warnings

This works:

switch (true) {
    case liCount == 0:
        setLayoutState('start');
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;
    case liCount<=5 && liCount>0:
        setLayoutState('upload1Row');
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;
    case liCount<=10 && liCount>5:
        setLayoutState('upload2Rows');
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;
    case liCount>10:
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;                  
}

A previous version of this answer considered the parentheses to be the culprit. In truth, the parentheses are irrelevant here - the only thing necessary is switch(true){...} and for your case expressions to evaluate to booleans.

It works because, the value we give to the switch is used as the basis to compare against. Consequently, the case expressions, also evaluating to booleans will determine which case is run. Could also turn this around, and pass switch(false){..} and have the desired expressions evaluate to false instead of true.. but personally prefer dealing with conditions that evaluate to truthyness. However, it does work too, so worth keeping in mind to understand what it is doing.

Eg: if liCount is 3, the first comparison is true === (liCount == 0), meaning the first case is false. The switch then moves on to the next case true === (liCount<=5 && liCount>0). This expression evaluates to true, meaning this case is run, and terminates at the break. I've added parentheses here to make it clearer, but they are optional, depending on the complexity of your expression.

It's pretty simple, and a neat way (if it fits with what you are trying to do) of handling a long series of conditions, where perhaps a long series of ìf() ... else if() ... else if () ... might introduce a lot of visual noise or fragility.

Use with caution, because it is a non-standard pattern, despite being valid code.

Had issues using the code in the answer provided by @haynar above (wouldn't play on Chrome), and it seems that one of the more modern ways to ensure it plays is to use the video tag

Example:

<video controls="controls" width="800" height="600" 
       name="Video Name" src="http://www.myserver.com/myvideo.mov"></video>

This worked like a champ for my .mov file (generated from Keynote) in both Safari and Chrome, and is listed as supported in most modern browsers (The video tag is supported in Internet Explorer 9+, Firefox, Opera, Chrome, and Safari.)

Note: Will work in IE / etc.. if you use MP4 (Mov is not officially supported by those guys)

For me, the main difference is that a script is interpreted, while a program is executed (i.e. the source is first compiled, and the result of that compilation is expected).

Wikipedia seems to agree with me on this :

Script :

"Scripts" are distinct from the core code of the application, which is usually written in a different language, and are often created or at least modified by the end-user.
Scripts are often interpreted from source code or bytecode, whereas the applications they control are traditionally compiled to native machine code.

Program :

The program has an executable form that the computer can use directly to execute the instructions.
The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled)

It seems that you can use the repository browser. Click the revision button at top-right and change it to the revision you want. Then right-click your file in the browser and use 'Copy to working copy...' but change the filename it will check out, to avoid a clash.

If the .stop() is deprecated then I don't think we should re-add it like @MuazKhan dose. It's a reason as to why things get deprecated and should not be used anymore. Just create a helper function instead... Here is a more es6 version

function stopStream (stream) {
    for (let track of stream.getTracks()) { 
        track.stop()
    }
}

If you have to select the id:

 DELETE FROM table WHERE id IN (SELECT id FROM somewhere_else)

If you already know them (and they are not in the thousands):

 DELETE FROM table WHERE id IN (?,?,?,?,?,?,?,?)

Short answer: Put the executable file in /usr/local/bin instead of applications. You should now be able to run commands like ngrok http 80.

Long answer: When you type commands like ngrok in the terminal, Macs (and other Unix OSs) look for these programs in the folders specified in your PATH. The PATH is a list of folders that's specified by each user. To check your path, open the terminal and type: echo $PATH.

You'll see output that looks something like: /usr/local/bin:/usr/bin:/bin. This is a : separated list of folders.

So when you type ngrok in the terminal, your Mac will look for this executable in the following folders: /usr/local/bin, /usr/bin/ and /bin.

Read this post if you are interested in learning about why you should prefer usr/local/bin over other folders.

I have toyed with this for forever, and finally found something that seems to always work!

textField = new JTextField() {

    public void addNotify() {
        super.addNotify();
        requestFocus();
    }
};

Don't forget to update your iptables firewall if you have one to allow the 20-21 and 1024-1048 ranges in.

Do this from /etc/sysconfig/iptables

Adding lines like this:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 20:21 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 1024:1048 -j ACCEPT

And restart iptables with the command:

sudo service iptables restart

The quick and dirty way is to simply swap out the iframe with one that has autoplay=1 set using jQuery.

THE HTML

Placeholder:

<div id="videoContainer">
  <iframe width="450" height="283" src="https://www.youtube.com/embed/VIDEO_ID_HERE?wmode=transparent" frameborder="0" allowfullscreen wmode="Opaque"></iframe>
</div>

Autoplay link:

<a class="introVid" href="#video">Watch the video</a></p>

THE JQUERY

The onClick catcher that calls the function

jQuery('a.introVid').click(function(){
  autoPlayVideo('VIDEO_ID_HERE','450','283');
});

The function

/*--------------------------------
  Swap video with autoplay video
---------------------------------*/

function autoPlayVideo(vcode, width, height){
  "use strict";
  $("#videoContainer").html('<iframe width="'+width+'" height="'+height+'" src="https://www.youtube.com/embed/'+vcode+'?autoplay=1&loop=1&rel=0&wmode=transparent" frameborder="0" allowfullscreen wmode="Opaque"></iframe>');
}

If a function does not return anything, e.g.:

def test():
    pass

it has an implicit return value of None.

Thus, as your pick* methods do not return anything, e.g.:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")

the lines that call them, e.g.:

word = pickEasy()

set word to None, so wordInput in getInput is None. This means that:

if guess in wordInput:

is the equivalent of:

if guess in None:

and None is an instance of NoneType which does not provide iterator/iteration functionality, so you get that type error.

The fix is to add the return type:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

I cannot help you much without a small (possibly reduced) snippit of the problem. If the problem is what I think it is then it's because a div by default takes up 100% width, and as such cannot be aligned.

What you may be after is to align the inline elements inside the div (such as text) with text-align:center; otherwise you may consider setting the div to display:inline-block;

If you do go down the inline-block route then you may have to consider my favorite IE hack.

width:100px;
display:inline-block;
zoom:1; //IE only
*display:inline; //IE only

Happy Coding :)

I won't make such a big deal from this question.
It's not like choosing your new wife or car.
I'd never run any of these on a production server, so, to run just some quick tests any of them are equally good.

The IE9 "version" of the WebBrowser control, like the IE8 version, is actually several browsers in one. Unlike the IE8 version, you do have a little more control over the rendering mode inside the page by changing the doctype. Of course, to change the browser mode you have to set your registry like the earlier answer. Here is a reg file fragment for FEATURE_BROWSER_EMULATION:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"contoso.exe"=dword:00002328

Here is the complete set of codes:

• 9999 (0x270F) - Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive.

If they are in the same controller class, it would be:

foreach ( $characters as $character) {
    $num += $this->getFactorial($index) * $index;
    $index ++;
}

Otherwise you need to create a new instance of the class, and call the method, ie:

$controller = new MyController();
foreach ( $characters as $character) {
    $num += $controller->getFactorial($index) * $index;
    $index ++;
}

That depends on what you want to do, but as you said, getting an entity reference using find() and then just updating that entity is the easiest way to do that.

I'd not bother about performance differences of the various methods unless you have strong indications that this really matters.

Answer

Sigh, it took me 45 minutes to find the answer to this simple question. The answer is: grepl(needle, haystack, fixed=TRUE)

# Correct
> grepl("1+2", "1+2", fixed=TRUE)
[1] TRUE
> grepl("1+2", "123+456", fixed=TRUE)
[1] FALSE

# Incorrect
> grepl("1+2", "1+2")
[1] FALSE
> grepl("1+2", "123+456")
[1] TRUE

Interpretation

grep is named after the linux executable, which is itself an acronym of "Global Regular Expression Print", it would read lines of input and then print them if they matched the arguments you gave. "Global" meant the match could occur anywhere on the input line, I'll explain "Regular Expression" below, but the idea is it's a smarter way to match the string (R calls this "character", eg class("abc")), and "Print" because it's a command line program, emitting output means it prints to its output string.

Now, the grep program is basically a filter, from lines of input, to lines of output. And it seems that R's grep function similarly will take an array of inputs. For reasons that are utterly unknown to me (I only started playing with R about an hour ago), it returns a vector of the indexes that match, rather than a list of matches.

But, back to your original question, what we really want is to know whether we found the needle in the haystack, a true/false value. They apparently decided to name this function grepl, as in "grep" but with a "Logical" return value (they call true and false logical values, eg class(TRUE)).

So, now we know where the name came from and what it's supposed to do. Lets get back to Regular Expressions. The arguments, even though they are strings, they are used to build regular expressions (henceforth: regex). A regex is a way to match a string (if this definition irritates you, let it go). For example, the regex a matches the character "a", the regex a* matches the character "a" 0 or more times, and the regex a+ would match the character "a" 1 or more times. Hence in the example above, the needle we are searching for 1+2, when treated as a regex, means "one or more 1 followed by a 2"... but ours is followed by a plus!

So, if you used the grepl without setting fixed, your needles would accidentally be haystacks, and that would accidentally work quite often, we can see it even works for the OP's example. But that's a latent bug! We need to tell it the input is a string, not a regex, which is apparently what fixed is for. Why fixed? No clue, bookmark this answer b/c you're probably going to have to look it up 5 more times before you get it memorized.

A few final thoughts

The better your code is, the less history you have to know to make sense of it. Every argument can have at least two interesting values (otherwise it wouldn't need to be an argument), the docs list 9 arguments here, which means there's at least 2^9=512 ways to invoke it, that's a lot of work to write, test, and remember... decouple such functions (split them up, remove dependencies on each other, string things are different than regex things are different than vector things). Some of the options are also mutually exclusive, don't give users incorrect ways to use the code, ie the problematic invocation should be structurally nonsensical (such as passing an option that doesn't exist), not logically nonsensical (where you have to emit a warning to explain it). Put metaphorically: replacing the front door in the side of the 10th floor with a wall is better than hanging a sign that warns against its use, but either is better than neither. In an interface, the function defines what the arguments should look like, not the caller (because the caller depends on the function, inferring everything that everyone might ever want to call it with makes the function depend on the callers, too, and this type of cyclical dependency will quickly clog a system up and never provide the benefits you expect). Be very wary of equivocating types, it's a design flaw that things like TRUE and 0 and "abc" are all vectors.

Since Java 7 you can use java.util.Objects.equals(Object a, Object b):

These utilities include null-safe or null-tolerant methods

Long id1 = null;
Long id2 = 0l;
Objects.equals(id1, id2));

You can close a figure by calling matplotlib.pyplot.close, for example:

from numpy import *
import matplotlib.pyplot as plt
from scipy import *

t = linspace(0, 0.1,1000)
w = 60*2*pi


fig = plt.figure()
plt.plot(t,cos(w*t))
plt.plot(t,cos(w*t-2*pi/3))
plt.plot(t,cos(w*t-4*pi/3))
plt.show()
plt.close(fig)

You can also close all open figures by calling matplotlib.pyplot.close("all")

Try the rename command in the folder with the files:

rename 's/^/Unix_/' *

The argument of rename (sed s command) indicates to replace the regex ^ with Unix_. The caret (^) is a special character that means start of the line.

1. You seem to be including one C file from anther. #include should normally be used with header files only.

2. Within the definition of struct ast_node you refer to struct AST_NODE, which doesn't exist. C is case-sensitive.

In your case here is a implementation using directions service.

function displayRoute() {

    var start = new google.maps.LatLng(28.694004, 77.110291);
    var end = new google.maps.LatLng(28.72082, 77.107241);

    var directionsDisplay = new google.maps.DirectionsRenderer();// also, constructor can get "DirectionsRendererOptions" object
    directionsDisplay.setMap(map); // map should be already initialized.

    var request = {
        origin : start,
        destination : end,
        travelMode : google.maps.TravelMode.DRIVING
    };
    var directionsService = new google.maps.DirectionsService(); 
    directionsService.route(request, function(response, status) {
        if (status == google.maps.DirectionsStatus.OK) {
            directionsDisplay.setDirections(response);
        }
    });
}

Another issue with using Strings as a primary key is that because the index is constantly put into sequential order, when a new key is created that would be in the middle of the order the index has to be resequenced... if you use an auto number integer, the new key is just added to the end of the index.

I am quite late answering this question (5 years to be exact) but I hope this helps someone.

I suspect that this error is because of the environment variables instead of GCC. When you set a new environment variable you need to open a new Command Prompt! This is the issue 90% of the time (when I first downloaded GCC I was stuck with this for 3 hours!) If this isn't the case, you probably haven't set the environment variables properly or you are in a folder with spaces in the name.

Once you have GCC working, it can be a hassle to compile and delete every time. If you don't want to install a full ide and already have python installed, try this github project: https://github.com/sophiadm/notepad-is-effort It is a small IDE written with tkinter in python.

@Navaneeth and @Antfish, no need to transform you can do like this also because in above solution only top border is visible so for inside curve you can use bottom border.

  height: 100px;_x000D_
  border: solid 5px #000;_x000D_
  border-color: transparent transparent #000 transparent;_x000D_
  border-radius: 0 0 240px 50%/60px;_x000D_
}

<div class="box"></div>

Like this:

$result1 = mysql_query($query1);
$result2 = mysql_query($query2);

// do something with the 2 result sets...

if ($result1)
    mysql_free_result($result1);

if ($result2)
    mysql_free_result($result2);

Try pm2 to make your application run forever.

npm install -g pm2

and then use

pm2 start server.js

The statement SELECT 1 FROM SomeTable just returns a column containing the value 1 for each row in your table. If you add another column in, e.g. SELECT 1, cust_name FROM SomeTable then it makes it a little clearer:

            cust_name
----------- ---------------

1           Kids Place
1           Fun4All
1           Fun4All
1           The Toy Store

try this

using System.Drawing;

I think the question is incomplete. if you meant that you wish to get the type information of some typeclass then below:

If you wish to print as you have specified then:

scala>  def manOf[T: Manifest](t: T): Manifest[T] = manifest[T]
manOf: [T](t: T)(implicit evidence$1: Manifest[T])Manifest[T]

scala> val x = List(1,2,3)
x: List[Int] = List(1, 2, 3)

scala> println(manOf(x))
scala.collection.immutable.List[Int]

If you are in repl mode then

scala> :type List(1,2,3)
List[Int]

Or if you just wish to know what the class type then as @monkjack explains "string".getClass might solve the purpose

Since IOS 9.0 use UIAlertController:

                                                          preferredStyle:UIAlertControllerStyleAlert];

                                                          //cancel action
                                                      }];
[alert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
    // A block for configuring the text field prior to displaying the alert
}];
[alert addAction:defaultAction];
[alert addAction:cancelAction];
[self presentViewController:alert animated:YES completion:nil];

Integers (int for short) are the numbers you count with 0, 1, 2, 3 ... and their negative counterparts ... -3, -2, -1 the ones without the decimal part.

So once you introduce a decimal point, your not really dealing with integers. You're dealing with rational numbers. The Python float or decimal types are what you want to represent or approximate these numbers.

You may be used to a language that automatically does this for you(Php). Python, though, has an explicit preference for forcing code to be explicit instead implicit.

FAQ

Questions from the top of my head since that time I gone crazy with jacoco.

My application server (jBoss, Glassfish..) located in Iraq, Syria, whatever.. Is it possible to get multi-module coverage when running integration tests on it? Jenkins and Sonar are also on different servers.

Yes. You have to use jacoco agent that runs in mode output=tcpserver, jacoco ant lib. Basically two jars. This will give you 99% success.

How does jacoco agent works?

You append a string

-javaagent:[your_path]/jacocoagent.jar=destfile=/jacoco.exec,output=tcpserver,address=*

to your application server JAVA_OPTS and restart it. In this string only [your_path] have to be replaced with the path to jacocoagent.jar, stored(store it!) on your VM where app server runs. Since that time you start app server, all applications that are deployed will be dynamically monitored and their activity (meaning code usage) will be ready for you to get in jacocos .exec format by tcl request.

Could I reset jacoco agent to start collecting execution data only since the time my test start?

Yes, for that purpose you need jacocoant.jar and ant build script located in your jenkins workspace.

So basically what I need from http://www.eclemma.org/jacoco/ is jacocoant.jar located in my jenkins workspace, and jacocoagent.jar located on my app server VM?

That's right.

I don't want to use ant, I've heard that jacoco maven plugin can do all the things too.

That's not right, jacoco maven plugin can collect unit test data and some integration tests data(see Arquillian Jacoco), but if you have for example rest assured tests as a separated build in jenkins, and want to show multi-module coverage, I can't see how maven plugin can help you.

What exactly does jacoco agent produce?

Only coverage data in .exec format. Sonar then can read it.

Does jacoco need to know where my java classes located are?

No, sonar does, but not jacoco. When you do mvn sonar:sonar path to classes comes into play.

So what about the ant script?

It has to be presented in your jenkins workspace. Mine ant script, I called it jacoco.xml looks like that:

<project name="Jacoco library to collect code coverage remotely" xmlns:jacoco="antlib:org.jacoco.ant">
    <property name="jacoco.port" value="6300"/>
    <property name="jacocoReportFile" location="${workspace}/it-jacoco.exec"/>

    <taskdef uri="antlib:org.jacoco.ant" resource="org/jacoco/ant/antlib.xml">
        <classpath path="${workspace}/tools/jacoco/jacocoant.jar"/>
    </taskdef>

    <target name="jacocoReport">
            <jacoco:dump address="${jacoco.host}" port="${jacoco.port}" dump="true" reset="true" destfile="${jacocoReportFile}" append="false"/>
    </target>

    <target name="jacocoReset">
            <jacoco:dump address="${jacoco.host}" port="${jacoco.port}" reset="true" destfile="${jacocoReportFile}" append="false"/>
        <delete file="${jacocoReportFile}"/>
    </target>
</project>

Two mandatory params you should pass when invoking this script -Dworkspace=$WORKSPACE use it to point to your jenkins workspace and -Djacoco.host=yourappserver.com host without http://

Also notice that I put my jacocoant.jar to ${workspace}/tools/jacoco/jacocoant.jar

What should I do next?

Did you start your app server with jacocoagent.jar?

Did you put ant script and jacocoant.jar in your jenkins workspace?

If yes the last step is to configure a jenkins build. Here is the strategy:

1. Invoke ant target jacocoReset to reset all previously collected data.
2. Run your tests
3. Invoke ant target jacocoReport to get report

If everything is right, you will see it-jacoco.exec in your build workspace.

Look at the screenshot, I also have ant installed in my workspace in $WORKSPACE/tools/ant dir, but you can use one that is installed in your jenkins.

How to push this report in sonar?

Maven sonar:sonar will do the job (don't forget to configure it), point it to main pom.xml so it will run through all modules. Use sonar.jacoco.itReportPath=$WORKSPACE/it-jacoco.exec parameter to tell sonar where your integration test report is located. Every time it will analyse new module classes, it will look for information about coverage in it-jacoco.exec.

I already have jacoco.exec in my `target` dir, `mvn sonar:sonar` ignores/removes it

By default mvn sonar:sonar does clean and deletes your target dir, use sonar.dynamicAnalysis=reuseReports to avoid it.

In bash you simply can ${var/find/replace}

PATH=${PATH/%:\/home\/wrong\/dir\//}

Or in this case (as the replace bit is empty) just:

PATH=${PATH%:\/home\/wrong\/dir\/}

I came here first but went else ware as I thought there would be a parameter expansion to do this. Easier than sed!.

Rotation Object programmatically.

// clockwise rotation :

    public void rotate_Clockwise(View view) {
        ObjectAnimator rotate = ObjectAnimator.ofFloat(view, "rotation", 180f, 0f);
//        rotate.setRepeatCount(10);
        rotate.setDuration(500);
        rotate.start();
    }

// AntiClockwise rotation :

 public void rotate_AntiClockwise(View view) {
        ObjectAnimator rotate = ObjectAnimator.ofFloat(view, "rotation", 0f, 180f);
//        rotate.setRepeatCount(10);
        rotate.setDuration(500);
        rotate.start();
    } 

view is object of your ImageView or other widgets.

rotate.setRepeatCount(10); use to repeat your rotation.

500 is your animation time duration.

Since mysql_connect has been deprecated, connect and query instead with mysqli:

$mysqli = new mysqli("hostname","username","password","database_name");
$sqlSelect="SELECT your_fieldname FROM your_table";
$result = $mysqli -> query ($sqlSelect);

And then, if you have more than one option list with the same values on the same page, put the values in an array:

while ($row = mysqli_fetch_array($result)) {
    $rows[] = $row;
}

And then you can loop the array multiple times on the same page:

foreach ($rows as $row) {
    print "<option value='" . $row['your_fieldname'] . "'>" . $row['your_fieldname'] . "</option>";
}

i think i'd try with MAX something like this:

SELECT staff_id, max( date ) from owner.table group by staff_id

then link in your other columns:

select staff_id, site_id, pay_level, latest

(   SELECT staff_id, max( date ) latest from owner.table group by staff_id ) m
where m.staff_id = staff_id
and m.latest = date

System.out.println(Integer.toBinaryString(2 << 11)); 

Shifts binary 2(10) by 11 times to the left. Hence: 1000000000000

System.out.println(Integer.toBinaryString(2 << 22)); 

Shifts binary 2(10) by 22 times to the left. Hence : 100000000000000000000000

System.out.println(Integer.toBinaryString(2 << 33)); 

Now, int is of 4 bytes,hence 32 bits. So when you do shift by 33, it's equivalent to shift by 1. Hence : 100

A socket represents a single connection between two network applications. These two applications nominally run on different computers, but sockets can also be used for interprocess communication on a single computer. Applications can create multiple sockets for communicating with each other. Sockets are bidirectional, meaning that either side of the connection is capable of both sending and receiving data. Therefore a socket can be created theoretically at any level of the OSI model from 2 upwards. Programmers often use sockets in network programming, albeit indirectly. Programming libraries like Winsock hide many of the low-level details of socket programming. Sockets have been in widespread use since the early 1980s.

A port represents an endpoint or "channel" for network communications. Port numbers allow different applications on the same computer to utilize network resources without interfering with each other. Port numbers most commonly appear in network programming, particularly socket programming. Sometimes, though, port numbers are made visible to the casual user. For example, some Web sites a person visits on the Internet use a URL like the following:

http://www.mairie-metz.fr:8080/ In this example, the number 8080 refers to the port number used by the Web browser to connect to the Web server. Normally, a Web site uses port number 80 and this number need not be included with the URL (although it can be).

In IP networking, port numbers can theoretically range from 0 to 65535. Most popular network applications, though, use port numbers at the low end of the range (such as 80 for HTTP).

Note: The term port also refers to several other aspects of network technology. A port can refer to a physical connection point for peripheral devices such as serial, parallel, and USB ports. The term port also refers to certain Ethernet connection points, such as those on a hub, switch, or router.

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

~/Global.asax.cs:

namespace ApplicationName
