Jackson

If you are using Jackson, then you can use the @JsonProperty annotation to customize the name of a given JSON property.

Therefore, you just have to annotate the entity fields with the @JsonProperty annotation and provide a custom JSON property name, like this:

@Entity
public class City {

   @Id
   @JsonProperty("value")
   private Long id;

   @JsonProperty("label")
   private String name;

   //Getters and setters omitted for brevity
}

JavaEE or JakartaEE JSON-B

JSON-B is the standard binding layer for converting Java objects to and from JSON. If you are using JSON-B, then you can override the JSON property name via the @JsonbProperty annotation:

@Entity
public class City {

   @Id
   @JsonbProperty("value")
   private Long id;

   @JsonbProperty("label")
   private String name;

   //Getters and setters omitted for brevity
}

Another alternative is to use DATE() function on the left hand operand as shown below

SELECT users.* FROM users WHERE DATE(created_at) BETWEEN '2011-12-01' AND '2011-12-06'

Concept Solution:br.read() returns particular character's int value so loop continue's until we won't get -1 as int value and Hence up to there it prints br.readLine() which returns a line into String form.

    //Way 1:
    while(br.read()!=-1)
    {
      //continues loop until we won't get int value as a -1
      System.out.println(br.readLine());
    }

    //Way 2:
    while((line=br.readLine())!=null)
    {
      System.out.println(line);
    }

    //Way 3:
    for(String line=br.readLine();line!=null;line=br.readLine())
    {
      System.out.println(line);
    }

Way 4: It's an advance way to read file using collection and arrays concept How we iterate using for each loop. check it here http://www.java67.com/2016/01/how-to-use-foreach-method-in-java-8-examples.html

I fixed this issue. As I'm using UpdatePanel, I added below code in the Page_Load event of the page and it worked for me:

protected void Page_Load(object sender, EventArgs e) {
  ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
  scriptManager.RegisterPostBackControl(this.btnExcelExport);
  //Further code goes here....
}

you can do

findViewById

from the radio group .

Here it is sample :

((RadioButton)my_radio_group.findViewById(R.id.radiobtn_veg)).setChecked(true);

This can be done pretty easily. All I did was move the existing directory, not under version control, to a temporary directory. Then I checked out the SVN version to my correct directory name, copied the files from the temporary directory into the SVN directory, and reverted the files in the SVN directory. If that does not make sense there is an example below:

/usr/local/www

mv www temp_www
svn co http://www.yourrepo.com/therepo www
cp -pR ./temp_www/* ./www
svn revert -R ./www/*
svn update

I hope this helps and am not sure why just a simple SVN update did not change the files back?

I would say that an object should implement Comparable if that is the clear natural way to sort the class, and anyone would need to sort the class would generally want to do it that way.

If, however, the sorting was an unusual use of the class, or the sorting only makes sense for a specific use case, then a Comparator is a better option.

Put another way, given the class name, is it clear how a comparable would sort, or do you have to resort to reading the javadoc? If it is the latter, odds are every future sorting use case would require a comparator, at which point the implementation of comparable may slow down users of the class, not speed them up.

this happened to me too after adding the version tag, that was missing, to the maven-war-plugin (not sure what version was using by default, i changed to the latest, 2.6 in my case). I had to wipe .m2/repository to have the build succeed again.

I tried first to clean the maven-filtering folder (in the repo) but then instead of a MavenFilterException i was getting an ArchiverException. So i concluded the local repository was corrupted (for a version upgrade?) and i deleted everything.

That fixed it for me. Just clean your local repo.

The first answer does't work anymore.

This worked for me:

from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium import webdriver

options = FirefoxOptions()
options.add_argument("--headless")
driver = webdriver.Firefox(options=options)
driver.get("http://google.com")

Lets try the shortest possible definition:

Lexical Scoping defines how variable names are resolved in nested functions: inner functions contain the scope of parent functions even if the parent function has returned.

That is all there is to it!

$file = '../image.jpg';
$type = 'image/jpeg';
header('Content-Type:'.$type);
header('Content-Length: ' . filesize($file));
readfile($file);

The provided answers are the best solution in your case, and they are what I do as well, but if your text is printed by a function or class method you could do the same as in Javascript as well

function hello(){
echo 'HELLO';
}
$print = true;
$print && hello();

This is the main difference between use git reset --hard and git reset --soft:

--soft

Does not touch the index file or the working tree at all (but resets the head to , just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

--hard

Resets the index and working tree. Any changes to tracked files in the working tree since are discarded.

For those who are looking for PHP ( >5.3.5 ) PDO statement, we can set charset as per below:

$dbh = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');

[ngClass]=... instead of *ngClass.

* is only for the shorthand syntax for structural directives where you can for example use

<div *ngFor="let item of items">{{item}}</div>

instead of the longer equivalent version

<template ngFor let-item [ngForOf]="items">
  <div>{{item}}</div>

Following is a sample of five different ways to summate values. The first is a naive way to perform the summation (and fails). The second attempts to use sprintf(), but it too fails. The third uses sprintf() successfully while the final two (4th & 5th) use floor($value + 0.5).

 use strict;
 use warnings;
 use POSIX;

 my @values = (26.67,62.51,62.51,62.51,68.82,79.39,79.39);
 my $total1 = 0.00;
 my $total2 = 0;
 my $total3 = 0;
 my $total4 = 0.00;
 my $total5 = 0;
 my $value1;
 my $value2;
 my $value3;
 my $value4;
 my $value5;

 foreach $value1 (@values)
 {
      $value2 = $value1;
      $value3 = $value1;
      $value4 = $value1;
      $value5 = $value1;

      $total1 += $value1;

      $total2 += sprintf('%d', $value2 * 100);

      $value3 = sprintf('%1.2f', $value3);
      $value3 =~ s/\.//;
      $total3 += $value3;

      $total4 += $value4;

      $total5 += floor(($value5 * 100.0) + 0.5);
 }

 $total1 *= 100;
 $total4 = floor(($total4 * 100.0) + 0.5);

 print '$total1: '.sprintf('%011d', $total1)."\n";
 print '$total2: '.sprintf('%011d', $total2)."\n";
 print '$total3: '.sprintf('%011d', $total3)."\n";
 print '$total4: '.sprintf('%011d', $total4)."\n";
 print '$total5: '.sprintf('%011d', $total5)."\n";

 exit(0);

 #$total1: 00000044179
 #$total2: 00000044179
 #$total3: 00000044180
 #$total4: 00000044180
 #$total5: 00000044180

Note that floor($value + 0.5) can be replaced with int($value + 0.5) to remove the dependency on POSIX.

if when decoding we get a string with ASCII characters, then the string was not encoded

(RoR) ruby solution:

def encoded?(str)
  Base64.decode64(str.downcase).scan(/[^[:ascii:]]/).count.zero?
end

def decoded?(str)
  Base64.decode64(str.downcase).scan(/[^[:ascii:]]/).count > 0
end

Replacing one string with another can be done in the below methods

Method 1: Using String replaceAll

 String myInput = "HelloBrother";
 String myOutput = myInput.replaceAll("HelloBrother", "Brother"); // Replace hellobrother with brother
 ---OR---
 String myOutput = myInput.replaceAll("Hello", ""); // Replace hello with empty
 System.out.println("My Output is : " +myOutput);       

Method 2: Using Pattern.compile

 import java.util.regex.Pattern;
 String myInput = "JAVAISBEST";
 String myOutputWithRegEX = Pattern.compile("JAVAISBEST").matcher(myInput).replaceAll("BEST");
 ---OR -----
 String myOutputWithRegEX = Pattern.compile("JAVAIS").matcher(myInput).replaceAll("");
 System.out.println("My Output is : " +myOutputWithRegEX);           

Method 3: Using Apache Commons as defined in the link below:

REFERENCE

Trying to write a REST API from scratch is not a simple task. There are many issues to factor and you will need to write a lot of code to process requests and data coming from the caller, authentication, retrieval of data and sending back responses.

Your best bet is to use a framework that already has this functionality ready and tested for you.

Some suggestions are:

Phalcon - REST API building - Easy to use all in one framework with huge performance

Apigility - A one size fits all API handling framework by Zend Technologies

and many more. Simple searches on Bitbucket/Github will give you a lot of resources to start with.

To see if a dataframe is empty, I argue that one should test for the length of a dataframe's columns index:

if len(df.columns) == 0: 1

Reason:

According to the Pandas Reference API, there is a distinction between:

• an empty dataframe with 0 rows and 0 columns
• an empty dataframe with rows containing NaN hence at least 1 column

Arguably, they are not the same. The other answers are imprecise in that df.empty, len(df), or len(df.index) make no distinction and return index is 0 and empty is True in both cases.

Examples

Example 1: An empty dataframe with 0 rows and 0 columns

In [1]: import pandas as pd
        df1 = pd.DataFrame()
        df1
Out[1]: Empty DataFrame
        Columns: []
        Index: []

In [2]: len(df1.index)  # or len(df1)
Out[2]: 0

In [3]: df1.empty
Out[3]: True

Example 2: A dataframe which is emptied to 0 rows but still retains n columns

In [4]: df2 = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
        df2
Out[4]:    AA  BB
        0   1  11
        1   2  22
        2   3  33

In [5]: df2 = df2[df2['AA'] == 5]
        df2
Out[5]: Empty DataFrame
        Columns: [AA, BB]
        Index: []

In [6]: len(df2.index)  # or len(df2)
Out[6]: 0

In [7]: df2.empty
Out[7]: True

Now, building on the previous examples, in which the index is 0 and empty is True. When reading the length of the columns index for the first loaded dataframe df1, it returns 0 columns to prove that it is indeed empty.

In [8]: len(df1.columns)
Out[8]: 0

In [9]: len(df2.columns)
Out[9]: 2

Critically, while the second dataframe df2 contains no data, it is not completely empty because it returns the amount of empty columns that persist.

Why it matters

Let's add a new column to these dataframes to understand the implications:

# As expected, the empty column displays 1 series
In [10]: df1['CC'] = [111, 222, 333]
         df1
Out[10]:    CC
         0 111
         1 222
         2 333
In [11]: len(df1.columns)
Out[11]: 1

# Note the persisting series with rows containing `NaN` values in df2
In [12]: df2['CC'] = [111, 222, 333]
         df2
Out[12]:    AA  BB   CC
         0 NaN NaN  111
         1 NaN NaN  222
         2 NaN NaN  333
In [13]: len(df2.columns)
Out[13]: 3

It is evident that the original columns in df2 have re-surfaced. Therefore, it is prudent to instead read the length of the columns index with len(pandas.core.frame.DataFrame.columns) to see if a dataframe is empty.

Practical solution

# New dataframe df
In [1]: df = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
        df
Out[1]:    AA  BB
        0   1  11
        1   2  22
        2   3  33

# This data manipulation approach results in an empty df
# because of a subset of values that are not available (`NaN`)
In [2]: df = df[df['AA'] == 5]
        df
Out[2]: Empty DataFrame
        Columns: [AA, BB]
        Index: []

# NOTE: the df is empty, BUT the columns are persistent
In [3]: len(df.columns)
Out[3]: 2

# And accordingly, the other answers on this page
In [4]: len(df.index)  # or len(df)
Out[4]: 0

In [5]: df.empty
Out[5]: True

# SOLUTION: conditionally check for empty columns
In [6]: if len(df.columns) != 0:  # <--- here
            # Do something, e.g. 
            # drop any columns containing rows with `NaN`
            # to make the df really empty
            df = df.dropna(how='all', axis=1)
        df
Out[6]: Empty DataFrame
        Columns: []
        Index: []

# Testing shows it is indeed empty now
In [7]: len(df.columns)
Out[7]: 0

Adding a new data series works as expected without the re-surfacing of empty columns (factually, without any series that were containing rows with only NaN):

In [8]: df['CC'] = [111, 222, 333]
         df
Out[8]:    CC
         0 111
         1 222
         2 333
In [9]: len(df.columns)
Out[9]: 1

A little modification on @kevinfahy 's answer, to allow getting the attribute by value if needed:

function getElementsByAttributeValue(attribute, value){
  var matchingElements = [];
  var allElements = document.getElementsByTagName('*');
  for (var i = 0, n = allElements.length; i < n; i++) {
    if (allElements[i].getAttribute(attribute) !== null) {
      if (!value || allElements[i].getAttribute(attribute) == value)
        matchingElements.push(allElements[i]);
    }
  }
  return matchingElements;
}

Simple code please check

SELECT * FROM table_name WHERE created <= (NOW() - INTERVAL 1 MONTH)

This might work a little better this way

A tuple is immutable and thus you get the error you posted.

>>> pixels = [1, 2, 3]
>>> pixels[0] = 5
>>> pixels = (1, 2, 3)
>>> pixels[0] = 5
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment

In your specific case, as correctly pointed out in other answers, you should write:

pixel = (pixel[0] + 20, pixel[1], pixel[2])

Answered by zerkms is the correct method. But, if someone looking to insert more extra column in the table then you can get it from the following:

INSERT INTO action_2_members (`campaign_id`, `mobile`, `email`, `vote`, `vote_date`, `current_time`)
SELECT `campaign_id`, `from_number`, '[email protected]', `received_msg`, `date_received`, 1502309889 FROM `received_txts` WHERE `campaign_id` = '8'

In the above query, there are 2 extra columns named email & current_time.

Use awk with a flag to trigger the print when necessary:

$ awk '/abc/{flag=1;next}/mno/{flag=0}flag' file
def1
ghi1
jkl1
def2
ghi2
jkl2

How does this work?

• /abc/ matches lines having this text, as well as /mno/ does.
• /abc/{flag=1;next} sets the flag when the text abc is found. Then, it skips the line.
• /mno/{flag=0} unsets the flag when the text mno is found.
• The final flag is a pattern with the default action, which is to print $0: if flag is equal 1 the line is printed.

For a more detailed description and examples, together with cases when the patterns are either shown or not, see How to select lines between two patterns?.

Here is an extension method that will convert an object to a ViewDataDictionary.

public static ViewDataDictionary ToViewDataDictionary(this object values)
{
    var dictionary = new ViewDataDictionary();
    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(values))
    {
        dictionary.Add(property.Name, property.GetValue(values));
    }
    return dictionary;
}

You can then use it in your view like so:

@Html.Partial("_MyPartial", new
{
    Property1 = "Value1",
    Property2 = "Value2"
}.ToViewDataDictionary())

Which is much nicer than the new ViewDataDictionary { { "Property1", "Value1" } , { "Property2", "Value2" }} syntax.

Then in your partial view, you can use ViewBag to access the properties from a dynamic object rather than indexed properties, e.g.

<p>@ViewBag.Property1</p>
<p>@ViewBag.Property2</p>

Simply supplying the HTML of elements you want to add to a jQuery constructor $() will return a jQuery object from newly built HTML, suitable for being appended into the DOM using jQuery's append() method.

For example:

var t = $("<table cellspacing='0' class='text'></table>");
$.append(t);

You could then populate this table programmatically, if you wished.

This gives you the ability to specify any arbitrary HTML you like, including class names or other attributes, which you might find more concise than using createElement and then setting attributes like cellSpacing and className via JS.

new String(byteArray, Charset.defaultCharset())

This will convert a byte array to the default charset in java. It may throw exceptions depending on what you supply with the byteArray.

You are somewhat close, but you should put your function inside the document.ready event handler instead of the other-way-around.

Another way to do this is by placing your AJAX call in a generic function and call that function from an AJAX callback to loop through a set of requests in order:

$(function () {

    //setup an array of AJAX options,
    //each object will specify information for a single AJAX request
    var ajaxes  = [
            {
                url      : '<url>',
                data     : {...},
                callback : function (data) { /*do work on data*/ }
            },
            {
                url      : '<url2>',
                data     : {...},
                callback : function (data) { /*maybe something different (maybe not)*/ }
            }
        ],
        current = 0;

    //declare your function to run AJAX requests
    function do_ajax() {

        //check to make sure there are more requests to make
        if (current < ajaxes.length) {

            //make the AJAX request with the given info from the array of objects
            $.ajax({
                url      : ajaxes[current].url,
                data     : ajaxes[current].data,
                success  : function (serverResponse) {

                    //once a successful response has been received,
                    //no HTTP error or timeout reached,
                    //run the callback for this request
                    ajaxes[current].callback(serverResponse);

                },
                complete : function () {

                    //increment the `current` counter
                    //and recursively call our do_ajax() function again.
                    current++;
                    do_ajax();

                    //note that the "success" callback will fire
                    //before the "complete" callback

                }
            });
        }
    }

    //run the AJAX function for the first time once `document.ready` fires
    do_ajax();

});

In this example, the recursive call to run the next AJAX request is being set as the complete callback so that it runs regardless of the status of the current response. Meaning that if the request times out or returns an HTTP error (or invalid response), the next request will still run. If you require subsequent requests to only run when a request is successful, then using the success callback to make your recursive call would likely be best.

JSONP or "JSON with padding" is a communication technique used in JavaScript programs running in web browsers to request data from a server in a different domain, something prohibited by typical web browsers because of the same-origin policy. JSONP takes advantage of the fact that browsers do not enforce the same-origin policy on script tags. Note that for JSONP to work, a server must know how to reply with JSONP-formatted results. JSONP does not work with JSON-formatted results.

http://en.wikipedia.org/wiki/JSONP

Good answer on stackoverflow: jQuery AJAX cross domain

   $.ajax({
        type: "GET",
        url: 'http://www.oxfordlearnersdictionaries.com/search/english/direct/',
        data:{q:idiom},
        async:true,
        dataType : 'jsonp',   //you may use jsonp for cross origin request
        crossDomain:true,
        success: function(data, status, xhr) {
            alert(xhr.getResponseHeader('Location'));
        }
    });

The file is truncated, so you can call read() (no exceptions raised, unlike when opened using 'w') but you'll get an empty string.

See the link below for information about how to use PreparedStatement. I have also quoted from the link.

http://docs.oracle.com/javase/tutorial/jdbc/basics/prepared.html

You must supply values in place of the question mark placeholders (if there are any) before you can execute a PreparedStatement object. Do this by calling one of the setter methods defined in the PreparedStatement class. The following statements supply the two question mark placeholders in the PreparedStatement named updateSales:

updateSales.setInt(1, e.getValue().intValue()); updateSales.setString(2, e.getKey());

Current Date using java 8: First, let's use java.time.LocalDate to get the current system date:

LocalDate localDate = LocalDate.now();

To get the date in any other timezone we can use LocalDate.now(ZoneId):

LocalDate localDate = LocalDate.now(ZoneId.of("GMT+02:30"));

We can also use java.time.LocalDateTime to get an instance of LocalDate:

LocalDateTime localDateTime = LocalDateTime.now();
LocalDate localDate = localDateTime.toLocalDate();

In Java 8, you can do it in a simpler and clean way :

if ("POST".equalsIgnoreCase(request.getMethod())) 
{
   test = request.getReader().lines().collect(Collectors.joining(System.lineSeparator()));
}

ADD following -

• look up for: # The MySQL server [mysqld]
• add this right below it: lower_case_table_names = 1 In file - /etc/mysql/mysql.conf.d/mysqld.cnf

It's works for me.

Assuming you are using Windows forms, you could allow the user to select a row and in the delete key click event. It is recommended that you allow the user to select 1 row only and not a group of rows (myDataGridView.MultiSelect = false)

Private Sub pbtnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click

        If myDataGridView.SelectedRows.Count > 0 Then
            'you may want to add a confirmation message, and if the user confirms delete
            myDataGridView.Rows.Remove(myDataGridView.SelectedRows(0))
        Else
            MessageBox.Show("Select 1 row before you hit Delete")

    End Sub

Note that this will not delete the row form the database until you perform the delete in the database.

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result
Begin
End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin
  <Function Body>
End

No, you can't, it doesn't support only year, so to do that you need a script, like jQuery or the webshim link you have, which shows year only.

If jQuery would be an option, here is one, borrowed from Sibu:

Javascript

$(function() {
    $( "#datepicker" ).datepicker({dateFormat: 'yy'});
});?

CSS

.ui-datepicker-calendar {
   display: none;
}

Here is an updated fiddle, without the month and prev/next buttons

If bootstrap is an option, check this link, they have a layout how you want.

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

The problem in my case was in the discrepancy between the Gradle version installed globally and the one required by React Native. To fix it, I had to update the folder android/gradle/wrapper from the current 6.5 RN version from GH.

I created a helper class just for this some time ago. Works great:

import java.util.concurrent.BrokenBarrierException;
import java.util.concurrent.CyclicBarrier;
/**
 * TimeOut class - used for stopping a thread that is taking too long
 * @author Peter Goransson
 *
 */
public class TimeOut {

    Thread interrupter;
    Thread target;
    long timeout;
    boolean success;
    boolean forceStop;

    CyclicBarrier barrier;

    /**
     * 
     * @param target The Runnable target to be executed
     * @param timeout The time in milliseconds before target will be interrupted or stopped
     * @param forceStop If true, will Thread.stop() this target instead of just interrupt() 
     */
    public TimeOut(Runnable target, long timeout, boolean forceStop) {      
        this.timeout = timeout;
        this.forceStop = forceStop;

        this.target = new Thread(target);       
        this.interrupter = new Thread(new Interrupter());

        barrier = new CyclicBarrier(2); // There will always be just 2 threads waiting on this barrier
    }

    public boolean execute() throws InterruptedException {  

        // Start target and interrupter
        target.start();
        interrupter.start();

        // Wait for target to finish or be interrupted by interrupter
        target.join();  

        interrupter.interrupt(); // stop the interrupter    
        try {
            barrier.await(); // Need to wait on this barrier to make sure status is set
        } catch (BrokenBarrierException e) {
            // Something horrible happened, assume we failed
            success = false;
        } 

        return success; // status is set in the Interrupter inner class
    }

    private class Interrupter implements Runnable {

        Interrupter() {}

        public void run() {
            try {
                Thread.sleep(timeout); // Wait for timeout period and then kill this target
                if (forceStop) {
                  target.stop(); // Need to use stop instead of interrupt since we're trying to kill this thread
                }
                else {
                    target.interrupt(); // Gracefully interrupt the waiting thread
                }
                System.out.println("done");             
                success = false;
            } catch (InterruptedException e) {
                success = true;
            }


            try {
                barrier.await(); // Need to wait on this barrier
            } catch (InterruptedException e) {
                // If the Child and Interrupter finish at the exact same millisecond we'll get here
                // In this weird case assume it failed
                success = false;                
            } 
            catch (BrokenBarrierException e) {
                // Something horrible happened, assume we failed
                success = false;
            }

        }

    }
}

It is called like this:

long timeout = 10000; // number of milliseconds before timeout
TimeOut t = new TimeOut(new PhotoProcessor(filePath, params), timeout, true);
try {                       
  boolean sucess = t.execute(); // Will return false if this times out
  if (!sucess) {
    // This thread timed out
  }
  else {
    // This thread ran completely and did not timeout
  }
} catch (InterruptedException e) {}  

Sure, just add & after the command:

read_cfg cfgA &
read_cfg cfgB &
read_cfg cfgC &
wait

all those jobs will then run in the background simultaneously. The optional wait command will then wait for all the jobs to finish.

Each command will run in a separate process, so it's technically not "multithreading", but I believe it solves your problem.

It doesn't always need to be toolkit-dependent or one doesn't always need use the FontMetrics approach since it requires one to first obtain a graphics object which is absent in a web container or in a headless enviroment.

I have tested this in a web servlet and it does calculate the text width.

import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;

...

String text = "Hello World";
AffineTransform affinetransform = new AffineTransform();     
FontRenderContext frc = new FontRenderContext(affinetransform,true,true);     
Font font = new Font("Tahoma", Font.PLAIN, 12);
int textwidth = (int)(font.getStringBounds(text, frc).getWidth());
int textheight = (int)(font.getStringBounds(text, frc).getHeight());

Add the necessary values to these dimensions to create any required margin.

1. Set var step=1 as global variable by putting it above the function call
2. put semicolons

It will look like this

<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
        var step=1;
        function slideit()
        {
            document.images.slide.src = eval("image"+step+".src");
            if(step<2)
                step++;
            else
                step=1;
            setTimeout("slideit()",2500);
        }
        slideit();
</script>
</body>

The answer by Pomber is acceptable, however I'm not a big fan of creating new objects repeatedly. The best solutions are always the ones that try to mitigate memory hog. Yes, there is auto garbage collection but memory conservation in a mobile device falls within the confines of best practice. The code below updates a TextView in a service.

TextViewUpdater textViewUpdater = new TextViewUpdater();
Handler textViewUpdaterHandler = new Handler(Looper.getMainLooper());
private class TextViewUpdater implements Runnable{
    private String txt;
    @Override
    public void run() {
        searchResultTextView.setText(txt);
    }
    public void setText(String txt){
        this.txt = txt;
    }

}

It can be used from anywhere like this:

textViewUpdater.setText("Hello");
        textViewUpdaterHandler.post(textViewUpdater);

If the data in your database is POSTED from HTML form TextArea controls, different browsers use different New Line characters:

Firefox separates lines with CHR(10) only

Internet Explorer separates lines with CHR(13) + CHR(10)

Apple (pre-OSX) separates lines with CHR(13) only

So you may need something like:

set col_name = replace(replace(col_name, CHR(13), ''), CHR(10), '')

An example,

 d <- data.frame(x1=rnorm(10),
                 x2=rnorm(10),
                 x3=rnorm(10))
cor(d) # get correlations (returns matrix)

There are 2 ways to configure custom error pages for ASP.NET sites:

1. Internet Information Services (IIS) Manager (the GUI)
2. web.config file

This article explains how to do each:

• How To Set Up Custom Error Pages In IIS 7.5 With ASP.NET

The reason your error.aspx page is not displaying might be because you have an error in your web.config. Try this instead:

<configuration>
   <system.web>
      <customErrors defaultRedirect="error.aspx" mode="RemoteOnly">
         <error statusCode="404" redirect="error.aspx"/>
      </customErrors>
   </system.web>
</configuration>

You might need to make sure that Error Pages in IIS Manager - Feature Delegation is set to Read/Write:

Also, this answer may help you configure the web.config file:

_x000D_
function showCheckboxes() {_x000D_
  var checkboxes = document.getElementById("checkboxes");_x000D_

Explanation:

At first we create a select element that shows text "Select an option", and empty element that covers (overlaps) the select element (<div class="overSelect">). We do not want the user to click on the select element - it would show an empty options. To overlap the element with other element we use CSS position property with value relative | absolute.

To add the functionality we specify a JavaScript function that is called when the user clicks on the div that contains our select element (<div class="selectBox" onclick="showCheckboxes()">).

We also create div that contains our checkboxes and style it using CSS. The above mentioned JavaScript function just changes <div id="checkboxes"> value of CSS display property from "none" to "block" and vice versa.

The solution was tested in the following browsers: Internet Explorer 10, Firefox 34, Chrome 39. The browser needs to have JavaScript enabled.

This is entirely inspired by laurasia's answer above, but it refines the structure.

It also adds some checks:

• It will correctly return 0 when searching an empty file for the empty string. In laurasia's answer, this is an edge case that will return -1.
• It also pre-checks whether the goal string is larger than the buffer size, and raises an error if this is the case.

In practice, the goal string should be much smaller than the buffer for efficiency, and there are more efficient methods of searching if the size of the goal string is very close to the size of the buffer.

def fnd(fname, goal, start=0, bsize=4096):
    if bsize < len(goal):
        raise ValueError("The buffer size must be larger than the string being searched for.")
    with open(fname, 'rb') as f:
        if start > 0:
            f.seek(start)
        overlap = len(goal) - 1
        while True:
            buffer = f.read(bsize)
            pos = buffer.find(goal)
            if pos >= 0:
                return f.tell() - len(buffer) + pos
            if not buffer:
                return -1
            f.seek(f.tell() - overlap)

Does it have to be done in Java? I.e. does it need to be platform independent? If not, I'd suggest using the 'split' command in *nix. If you really wanted, you could execute this command via your java program. While I haven't tested, I imagine it perform faster than whatever Java IO implementation you could come up with.

WHERE something IS NULL

and

WHERE something IS NOT NULL

There are two events on client side as given below.

1. window.onbeforeunload (calls on Browser/tab Close & Page Load)

2. window.onload (calls on Page Load)

On server Side

public JsonResult TestAjax( string IsRefresh)
    {
        JsonResult result = new JsonResult();
        return result = Json("Called", JsonRequestBehavior.AllowGet);
    }

On Client Side

 <script type="text/javascript">_x000D_
    window.onbeforeunload = function (e) {_x000D_
        _x000D_
        $.ajax({_x000D_
            type: 'GET',_x000D_
            async: false,_x000D_
            url: '/Home/TestAjax',_x000D_
            data: { IsRefresh: 'Close' }_x000D_
        });_x000D_
    };_x000D_
_x000D_
    window.onload = function (e) {_x000D_
_x000D_
        $.ajax({_x000D_
            type: 'GET',_x000D_
            async: false,_x000D_
            url: '/Home/TestAjax',_x000D_
            data: {IsRefresh:'Load'}_x000D_
        });_x000D_
    };_x000D_
</script>

On Browser/Tab Close: if user close the Browser/tab, then window.onbeforeunload will fire and IsRefresh value on server side will be "Close".

On Refresh/Reload/F5: If user will refresh the page, first window.onbeforeunload will fire with IsRefresh value = "Close" and then window.onload will fire with IsRefresh value = "Load", so now you can determine at last that your page is refreshing.

^wp.*\.php$ Should do the trick.

The .* means "any character, repeated 0 or more times". The next . is escaped because it's a special character, and you want a literal period (".php"). Don't forget that if you're typing this in as a literal string in something like C#, Java, etc., you need to escape the backslash because it's a special character in many literal strings.

Webservices require unique namespaces so they don't confuse each others schemas and whatever with each other. A URL (domain, subdomain, subsubdomain, etc) is a clever identifier as it's "guaranteed" to be unique, and in most circumstances you've already got one.

Using only "native" Windows utilities, try the following, where "516" is the process ID that you want the image name for:

for /f "delims=," %a in ( 'tasklist /fi "PID eq 516" /nh /fo:csv' ) do ( echo %~a )
for /f %a in ( 'tasklist /fi "PID eq 516" ^| findstr "516"' ) do ( echo %a )

Or you could use wmic (the Windows Management Instrumentation Command-line tool) and get the full path to the executable:

wmic process where processId=516 get name
wmic process where processId=516 get ExecutablePath

Or you could download Microsoft PsTools, or specifically download just the pslist utility, and use PsList:

for /f %a in ( 'pslist 516 ^| findstr "516"' ) do ( echo %a )

Re-posted as an answer: Found an alternative (Tested in Win8):

cmdkey /generic:"<server>" /user:"<user>" /pass:"<pass>"

Run that and if you run:

mstsc /v:<server>

You should not get an authentication prompt.

The easiest way is to use the `` feature in Perl. This will execute what is inside and return what was printed to stdout:

 my $pid = 5892;
 my $var = `top -H -p $pid -n 1 | grep myprocess | wc -l`;
 print "not = $var\n";

This should do it.

SET @date1 = '2010-10-11 12:15:35', @date2 = '2010-10-10 00:00:00';

SELECT 
TIMEDIFF(@date1, @date2) AS 'TIMEDIFF',
TIMESTAMPDIFF(hour, @date1, @date2) AS 'Hours',
TIMESTAMPDIFF(minute, @date1, @date2) AS 'Minutes',
TIMESTAMPDIFF(second, @date1, @date2) AS 'Seconds';

RESULTS

TIMEDIFF : 36:15:35
Hours : -36
Minutes : -2175
Seconds : -130535

you need to use the htmlAttributes anonymous object, like this:

<%= Html.ActionLink("linky", "action", "controller", new { onclick = "someFunction();"}) %>

you could also give it an id an attach to it with jquery/whatever, like this:

<%= Html.ActionLink("linky", "action", "controller", new { id = "myLink" }) %>


$('#myLink').click(function() { /* bla */ });

looks like bad architecture all the way. also you have not specified the type of app you need to notify to (web app / console app / winforms / service etc etc)

nevertheless, to answer your question, there are multiple ways of solving this. you could use:

1) timestamps if you were just interested in ensuring the next set of updates from the second app dont conflict with the updates from the first app

2) sql dependency object - see http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldependency.aspx for more info

3) a custom push notification service which multiple clients (web / winform / service) can subscribe to and get notified on changes

in short, you need to use the simplest and easiest and cheapest (in terms of efforts) solution based on how complex your notification requirements are and for what purpose you need to use them. dont try to build an overly complex notification system if a simple data concurrency is your only requirement (in that case go for a simple timestamp based solution)

    'mail' => [

I'm using

$("input:radio[name='html_radio']").is(":checked")

And will return FALSE if all the items in the radiogroup are unchecked and TRUE if an item is checked.

The solution of Quango in is working but I prefer to resolve it by adding this code in my Web.config like new projects :

<system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs"
        type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=3.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

If you pass a DateTime from a .Net code to a javascript code, C#:

DateTime net_datetime = DateTime.Now;

javascript treats it as a string, like "/Date(1245398693390)/":

You can convert it as fllowing:

// convert the string to date correctly
var d = eval(net_datetime.slice(1, -1))

or:

// convert the string to date correctly
var d = eval("/Date(1245398693390)/".slice(1, -1))

//How decodeURIComponent Works

function proURIDecoder(val)
{
  val=val.replace(/\+/g, '%20');
  var str=val.split("%");
  var cval=str[0];
  for (var i=1;i<str.length;i++)
  {
    cval+=String.fromCharCode(parseInt(str[i].substring(0,2),16))+str[i].substring(2);
  }

  return cval;
}

document.write(proURIDecoder(window.location.href));

Make a selector for Individaual item of Nav Drawer

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/darkBlue" android:state_pressed="true"/>
    <item android:drawable="@color/darkBlue" android:state_checked="true"/>
    <item android:drawable="@color/textBlue" />
</selector>

Make a few changes in your NavigationView

<android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:itemBackground="@drawable/drawer_item"
        android:background="@color/textBlue"
        app:itemIconTint="@color/white"
        app:itemTextColor="@color/white"
        app:menu="@menu/activity_main_drawer"
        />

A warning by which the compiler indicates that it cannot ensure type safety. The term "unchecked" warning is misleading. It does not mean that the warning is unchecked in any way. The term "unchecked" refers to the fact that the compiler and the runtime system do not have enough type information to perform all type checks that would be necessary to ensure type safety. In this sense, certain operations are "unchecked".

The most common source of "unchecked" warnings is the use of raw types. "unchecked" warnings are issued when an object is accessed through a raw type variable, because the raw type does not provide enough type information to perform all necessary type checks.

Example (of unchecked warning in conjunction with raw types):

TreeSet set = new TreeSet(); 
set.add("abc");        // unchecked warning 
set.remove("abc");

warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.TreeSet 
               set.add("abc");  
                      ^

When the add method is invoked the compiler does not know whether it is safe to add a String object to the collection. If the TreeSet is a collection that contains String s (or a supertype thereof), then it would be safe. But from the type information provided by the raw type TreeSet the compiler cannot tell. Hence the call is potentially unsafe and an "unchecked" warning is issued.

"unchecked" warnings are also reported when the compiler finds a cast whose target type is either a parameterized type or a type parameter.

Example (of an unchecked warning in conjunction with a cast to a parameterized type or type variable):

  class Wrapper<T> { 
  private T wrapped ; 
  public Wrapper (T arg) {wrapped = arg;} 
  ... 
  public Wrapper <T> clone() { 
    Wrapper<T> clon = null; 
     try {  
       clon = (Wrapper<T>) super.clone(); // unchecked warning 
     } catch (CloneNotSupportedException e) {  
       throw new InternalError();  
     } 
     try {  
       Class<?> clzz = this.wrapped.getClass(); 
       Method   meth = clzz.getMethod("clone", new Class[0]); 
       Object   dupl = meth.invoke(this.wrapped, new Object[0]); 
       clon.wrapped = (T) dupl; // unchecked warning 
     } catch (Exception e) {} 
     return clon; 
  } 
} 

warning: [unchecked] unchecked cast 
found   : java.lang.Object 
required: Wrapper <T> 
                  clon = ( Wrapper <T>)super.clone();  
                                                ^ 
warning: [unchecked] unchecked cast 
found   : java.lang.Object 
required: T 
                  clon. wrapped = (T)dupl;

A cast whose target type is either a (concrete or bounded wildcard) parameterized type or a type parameter is unsafe, if a dynamic type check at runtime is involved. At runtime, only the type erasure is available, not the exact static type that is visible in the source code. As a result, the runtime part of the cast is performed based on the type erasure, not on the exact static type.

In the example, the cast to Wrapper would check whether the object returned from super.clone is a Wrapper , not whether it is a wrapper with a particular type of members. Similarly, the casts to the type parameter T are cast to type Object at runtime, and probably optimized away altogether. Due to type erasure, the runtime system is unable to perform more useful type checks at runtime.

In a way, the source code is misleading, because it suggests that a cast to the respective target type is performed, while in fact the dynamic part of the cast only checks against the type erasure of the target type. The "unchecked" warning is issued to draw the programmer's attention to this mismatch between the static and dynamic aspect of the cast.

Please refer: What is an "unchecked" warning?

I've written a library that helps do precisely this. It allows search by object simply by initializing only the fields you want to filter by: https://github.com/kg6zvp/GenericEntityEJB

You can convert the java.util.Date object into a String object, which will format the date as yyyy-mm-dd.

LocalDate has a parse method that will convert it to a LocalDate object. The string must represent a valid date and is parsed using DateTimeFormatter.ISO_LOCAL_DATE.

Date to LocalDate

LocalDate.parse(Date.toString())

Hm. You have to specify window you clicked in Mouse.GetPosition(IInputElement relativeTo) Following code works well for me

protected override void OnMouseDown(MouseButtonEventArgs e)
    {
        base.OnMouseDown(e);
        Point p = e.GetPosition(this);
    }

I suspect that you need to refer to the window not from it own class but from other point of the application. In this case Application.Current.MainWindow will help you.

For AWS users who work with Amazon SES in conjunction with PHPMailer, this error also appears when your "from" mail sender isn't a verified sender.

To add a verified sender:

1. Log in to your Amazon AWS console: https://console.aws.amazon.com

2. Select "Amazon SES" from your list of available AWS applications

3. Select, under "Verified Senders", the "Email Addresses" --> "Verify a new email address"

4. Navigate to that new sender's email, click the confirmation e-mail's link.

And you're all set.

I think the other answers miss one important detail regarding the property name to use in the EL expression. The rules for converting from the method names to property names are specified in 'Introspector.decpitalize` which is part of the java bean standard:

This normally means converting the first character from upper case to lower case, but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone.

Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "URL".

So in your case the JSTL code should look like the following, note the capital 'P':

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

I have used Dropbox as my Prive or protected svn. Try the link below. http://foyzulkarim.blogspot.com/2012/12/dropbox-as-svn-repository.html

I think the simplest way is:

dos2unix $(find . -type f)

LinearLayout supports assigning a weight to individual children. This attribute assigns an "importance" value to a view, and allows it to expand to fill any remaining space in the parent view. Default weight is zero

calculation to assign any Remaining/Extra space between child. (not the total space)

space assign to child = (child individual weight) / (sum of weight of every child in Linear Layout)

Example (1): if there are three text boxes and two of them declare a weight of 1, while the third one is given no weight (0), then Remaining/Extra space assign to

1st text box = 1/(1+1+0) 
2nd text box = 1/(1+1+0) 
3rd text box = 0/(1+1+0) 

Example (2) : let's say we have a text label and two text edit elements in a horizontal row. The label has no layout_weight specified, so it takes up the minimum space required to render. If the layout_weight of each of the two text edit elements is set to 1, the remaining width in the parent layout will be split equally between them (because we claim they are equally important).

calculation : 
1st label = 0/(0+1+1) 
2nd text box = 1/(0+1+1) 
3rd text box = 1/(0+1+1)

If the first one text box has a layout_weight of 1 and the second text box has a layout_weight of 2, then one third of the remaining space will be given to the first, and two thirds to the second (because we claim the second one is more important).

calculation : 
1st label = 0/(0+1+2) 
2nd text box = 1/(0+1+2) 
3rd text box = 2/(0+1+2) 

In answer to your first question, there's no parameter substitution because you've put the delimiter in quotes - the bash manual says:

The format of here-documents is:

      <<[-]word
              here-document
      delimiter

No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. [...]

If you change your first example to use <<EOF instead of << "EOF" you'll find that it works.

In your second example, the shell invokes sudo only with the parameter cat, and the redirection applies to the output of sudo cat as the original user. It'll work if you try:

sudo sh -c "cat > /path/to/outfile" <<EOT
my text...
EOT

As you've already noticed, you can control most of these settings in .csproj.

If you'd rather keep these in AssemblyInfo.cs, you can turn off auto-generated assembly attributes.

<PropertyGroup>
   <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
</PropertyGroup> 

If you want to see what's going on under the hood, checkout Microsoft.NET.GenerateAssemblyInfo.targets inside of Microsoft.NET.Sdk.

Ultimately they both produce the same HTML but Html.TextBoxFor() is strongly typed where as Html.TextBox isn't.

1:  @Html.TextBox("Name")
2:  Html.TextBoxFor(m => m.Name)

will both produce

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

So what does that mean in terms of use?

Generally two things:

1. The typed TextBoxFor will generate your input names for you. This is usually just the property name but for properties of complex types can include an underscore such as 'customer_name'
2. Using the typed TextBoxFor version will allow you to use compile time checking. So if you change your model then you can check whether there are any errors in your views.

It is generally regarded as better practice to use the strongly typed versions of the HtmlHelpers that were added in MVC2.

I needed the absolute total count after applying the aggregation. This worked for me:

db.mycollection.aggregate([
    {
        $group: { 
            _id: { field1: "$field1", field2: "$field2" },
        }
    },
    { 
        $group: { 
            _id: null, count: { $sum: 1 } 
        } 
    }
])

Result:

{
    "_id" : null,
    "count" : 57.0
}

https://golang.org/ref/spec#For_range

A "for" statement with a "range" clause iterates through all entries of an array, slice, string or map, or values received on a channel. For each entry it assigns iteration values to corresponding iteration variables and then executes the block.

As an example:

for index, element := range someSlice {
    // index is the index where we are
    // element is the element from someSlice for where we are
}

If you don't care about the index, you can use _:

for _, element := range someSlice {
    // element is the element from someSlice for where we are
}

The underscore, _, is the blank identifier, an anonymous placeholder.

You're using smart quotes. That is, instead of standard quotation marks ("), you are using curly quotes (”). This happens automatically with Microsoft Word and other word processors to make things look prettier, but it also mangles HTML. Make sure to code in a plain text editor, like Notepad or Notepad2.

If you are already extending from ActionBarActivity and you are trying to get the action bar from a fragment:

ActionBar mActionBar = (ActionBarActivity)getActivity()).getSupportActionBar();

If you want to pass a JavaScript object/hash (ie. an associative array in PHP) then you would do:

$.post('/url/to/page', {'key1': 'value', 'key2': 'value'});

If you wanna pass an actual array (ie. an indexed array in PHP) then you can do:

$.post('/url/to/page', {'someKeyName': ['value','value']});

If you want to pass a JavaScript array then you can do:

$.post('/url/to/page', {'someKeyName': variableName});

In line with @Qwertie's suggestion, but going further on the lazy side, you could just pretend that each byte is a ISO-8859-1 character. For the uninitiated, ISO-8859-1 is a single-byte encoding that matches the first 256 code points of Unicode.

So @Ash's answer is actually redeemable with a charset:

byte[] args2 = getByteArry();
String byteStr = new String(args2, Charset.forName("ISO-8859-1"));

This encoding has the same readability as BAIS, with the advantage that it is processed faster than either BAIS or base64 as less branching is required. It might look like the JSON parser is doing a bit more, but it's fine because dealing with non-ASCII by escaping or by UTF-8 is part of a JSON parser's job anyways. It could map better to some formats like MessagePack with a profile.

Space-wise however, it is usually a loss, as nobody would be using UTF-16 for JSON. With UTF-8 each non-ASCII byte would occupy 2 bytes, while BAIS uses (2+4n + r?(r+1):0) bytes for every run of 3n+r such bytes (r is the remainder).

If you don't want to make the button a separate image, you can use the <area> tag. This is done by using html similar to this:

<img src="imgsrc" width="imgwidth" height="imgheight" alt="alttext" usemap="#mapname">

<map name="mapname">
    <area shape="rect" coords="see note 1" href="link" alt="alttext">
</map>

Note 1: The coords=" " attribute must be formatted in this way: coords="x1,y1,x2,y2" where:

x1=top left X coordinate
y1=top left Y coordinate
x2=bottom right X coordinate
y2=bottom right Y coordinate

Note 2: The usemap="#mapname" attribute must include the #.

EDIT:

I looked at your code and added in the <map> and <area> tags where they should be. I also commented out some parts that were either overlapping the image or seemed there for no use.

<div class="flexslider">
    <ul class="slides" runat="server" id="Ul">

                <map name="imgmap">
                    <area shape="rect" coords="48,341,294,275" href="http://www.example.com/">
                </map>
                <!--<a href="#" style="display:block; background:#00F; width:356px; height:66px; position:absolute; left:1px; top:-19px; left: 162px; top: 279px;"></a>-->
            </div>
        </li>
    </ul>
</div>
<!-- <ul class="flex-direction-nav">
    <li><a class="flex-prev" href="#"><i class="icon-angle-left"></i></a></li>
    <li><a class="flex-next" href="#"><i class="icon-angle-right"></i></a></li>
</ul> -->

Notes:

1. The coord="48,341,294,275" is in reference to your screenshot you posted.
2. The src="./test.png" is the location and name of the screenshot you posted on my computer.
3. The href="http://www.example.com/" is an example link.

Here is the solution.

The HTML:

<table cellspacing="0" cellpadding="0">
    <tr>
        <td>
            123
        </td>
    </tr>
</table>

The CSS:

table { 
      border-spacing:0; 
      border-collapse:collapse;   
    }

Hope this helps.

EDIT

td, th {padding:0}

$('div.alldivs :first-child');

Or you can just refer to the id directly:

$('#div1');

As suggested, you might be better of using the child selector:

$('div.alldivs > div:first-child')

If you dont have to use first-child, you could use :first as also suggested, or $('div.alldivs').children(0).

This can also be done using a wrapper. Very general way of keeping time.

The wrapper in this example code wraps any function and prints the amount of time needed to execute the function:

def timethis(f):
    import time

    def wrapped(*args, **kwargs):
        start = time.time()
        r = f(*args, **kwargs)
        print "Executing {0} took {1} seconds".format(f.func_name,  time.time()-start)
        return r
    return wrapped

@timethis
def thistakestime():
    for x in range(10000000):
        pass

thistakestime()

In order to be able to expose some configuration parameters for your bundle you should consult the documentation for doing so. It's fairly easy to do :)

Here's the link: How to expose a Semantic Configuration for a Bundle

Some of the answers have already provided various approaches related to getting rid of the create extension and comment on extensions. For me, the following command line seemed to work and be the simplest approach to solve the problem:

cat /tmp/backup.sql.gz | gunzip - | \
  grep -v -E '(CREATE\ EXTENSION|COMMENT\ ON)' |  \
    psql --set ON_ERROR_STOP=on -U db_user -h localhost my_db

Some notes

• The first line is just uncompressing my backup and you may need to adjust accordingly.
• The second line is using grep to get rid of offending lines.
• the third line is my psql command; you may need to adjust as you normally would use psql for restore.

Delete any branch that isn't up to date with master

git co master && git branch | sed s/\*/\ / | xargs git branch -d 2> /dev/null

Maybe I'm a bit of late to answer this question, but I'm working on this subject at my job :)

I wanted to write column 'a_code' = c1,c2,c3,c4...

Firstly I opened a column with the name ref_id and the type serial. Then I solved my problem with this command:

update myschema.mytable set a_code=cast('c'||"ref_id" as text) 

Another option is:

<script language="JavaScript" type="text/javascript"> 
document.getElementById("my_date:box").value = ( Stamp.getDate()+"/"+(Stamp.getMonth() + 1)+"/"+(Stamp.getYear()) );
</script>

Just complementing what Devart said, the below code is not ordering according to the question:

SELECT t1.* FROM messages t1
  JOIN (SELECT from_id, MAX(timestamp) timestamp FROM messages GROUP BY from_id) t2
    ON t1.from_id = t2.from_id AND t1.timestamp = t2.timestamp;

The "GROUP BY" clause must be in the main query since that we need first reorder the "SOURCE" to get the needed "grouping" so:

SELECT t1.* FROM messages t1
  JOIN (SELECT from_id, MAX(timestamp) timestamp FROM messages ORDER BY timestamp DESC) t2
    ON t1.from_id = t2.from_id AND t1.timestamp = t2.timestamp GROUP BY t2.timestamp;

Regards,

Yeah Regex is cool, but there are other alternative.

• Select all the lines you want to prefix or suffix
• Goto menu Selection -> Split into Lines (Cmd/Ctrl + Shift + L)

This allows you to edit multiple lines at once. Now you can add *Quotes (") or anything * at start and end of each lines.

The other answers already cover that you can simply git add NEW && git rm OLD in order to make git recognize the move.

However, if you have already modified the file in the working directory, the add+rm approach will add the modifications to the index, which may be undesired in some cases (e.g. in case of substantial modifications, git might not recognize anymore that it is a file rename).

Let's assume you want to add the rename to the index, but not any modifications. The obvious way to achieve this, is to do a back and forth rename mv NEW OLD && git mv OLD NEW.

But there is also a (slighty more complicated) way to do this directly in the index without renaming the file in the working tree:

info=$(git ls-files -s -- "OLD" | cut -d' ' -f-2 | tr ' ' ,)
git update-index --add --cacheinfo "$info,NEW" &&
git rm --cached "$old"

This can also be put as an alias in your ~/.gitconfig:

[alias]
    mv-index = "!f() { \
      old=\"$1\"; \
      new=\"$2\"; \
      info=$(git ls-files -s -- \"$old\" | cut -d' ' -f-2 | tr ' ' ,); \
      git update-index --add --cacheinfo \"$info,$new\" && \
      git rm --cached \"$old\"; \
    }; f"

SELECT 
    a.nameA, /* TableA.nameA */
    d.nameD /* TableD.nameD */
FROM TableA a 
    INNER JOIN TableB b on b.aID = a.aID 
    INNER JOIN TableC c on c.cID = b.cID 
    INNER JOIN TableD d on d.dID = a.dID 
WHERE DATE(c.`date`) = CURDATE()

Since 2017 and Symfony 3.3 you can register Repository as service, with all its advantages it has.

Check my post How to use Repository with Doctrine as Service in Symfony for more general description.

To your specific case, original code with tuning would look like this:

1. Use in your services or Controller

<?php

namespace Test\CommonBundle\Services;

use Doctrine\ORM\EntityManagerInterface;

class UserService
{
    private $userRepository;

    // use custom repository over direct use of EntityManager
    // see step 2
    public function __constructor(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }

    public function getUser($userId)
    {
        return $this->userRepository->find($userId);
    }
}

2. Create new custom repository

<?php

namespace Test\CommonBundle\Repository;

use Doctrine\ORM\EntityManagerInterface;

class UserRepository
{
    private $repository;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->repository = $entityManager->getRepository(UserEntity::class);
    }

    public function find($userId)
    {
        return  $this->repository->find($userId);
    }
}

3. Register services

# app/config/services.yml
services:
    _defaults:
        autowire: true

    Test\CommonBundle\:
       resource: ../../Test/CommonBundle

you seem to have not created an main method, which should probably look something like this (i am not sure)

  class RunThis
{
    public static void main(String[] args)
    {

    Calculate answer = new Calculate();
    answer.getNumber1();
    answer.getNumber2();
    answer.setNumber(answer.getNumber1() , answer.getNumber2());
    answer.getOper();
    answer.setOper(answer.getOper());
    answer.getAnswer();
    }
}

the point is you should have created a main method under some class and after compiling you should run the .class file containing main method. In this case the main method is under RunThis i.e RunThis.class.

I am new to java this may or may not be the right answer, correct me if i am wrong

For Add and Remove ViewController

 var secondViewController :SecondViewController?

  // Adding 
 func add_ViewController() {
    let controller  = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController")as! SecondViewController
    controller.view.frame = self.view.bounds
    self.view.addSubview(controller.view)
    self.addChild(controller)
    controller.didMove(toParent: self)
    self.secondViewController = controller
}

// Removing
func remove_ViewController(secondViewController:SecondViewController?) {
    if secondViewController != nil {
        if self.view.subviews.contains(secondViewController!.view) {
             secondViewController!.view.removeFromSuperview()
        }
        
    }
}

I found that Apache2 (you might want to also check Apache 1.5) has a way to restrict this before uploading by dropping this in your .htaccess file:

LimitRequestBody 2097152

This restricts it to 2 megabytes (2 * 1024 * 1024) on file upload (if I did my byte math properly).

Note when you do this, the Apache error log will generate this entry when you exceed this limit on a form post or get request:

Requested content-length of 4000107 is larger than the configured limit of 2097152

And it will also display this message back in the web browser:

<h1>Request Entity Too Large</h1>

So, if you're doing AJAX form posts with something like the Malsup jQuery Form Plugin, you could trap for the H1 response like this and show an error result.

By the way, the error number returned is 413. So, you could use a directive in your .htaccess file like...

Redirect 413 413.html

...and provide a more graceful error result back.

On a Mac do this:

cmd + , or ADT -> Preferences 

Expand General -> Editors ->Text Editors

Check box: Show line numbers

The callback to $.each() is passed the property name and the value, in that order. You're therefore trying to iterate over the property names in the inner call to $.each(). I think you want:

$.each(myMap, function (i, val) {
  $.each(val, function(innerKey, innerValue) {
    // ...
  });
});

In the inner loop, given an object like your map, the values are arrays. That's OK, but note that the "innerKey" values will all be numbers.

edit — Now once that's straightened out, here's the next problem:

    setTimeout(function () {

      // ...

    }, i * 6000);

The first time through that loop, "i" will be the string "partnr1". Thus, that multiplication attempt will result in a NaN. You can keep an external counter to keep track of the property count of the outer map:

var pcount = 1;
$.each(myMap, function(i, val) {
  $.each(val, function(innerKey, innerValue) {
    setTimeout(function() {
      // ...
    }, pcount++ * 6000);
  });
});

Step 1

We need set format data in function date(): Function date() returns a string formatted according to the givenformat string using the given integer timestamp or the current time ifno timestamp is given. In other words, timestampis optional anddefaults to the value of time().

<?php
echo date("F j, Y");
?>

result: March 30, 2010

Step 2

For "yesterday" date use php function mktime(): Function mktime() returns the Unix timestamp corresponding to thearguments given. This timestamp is a long integer containing the numberof seconds between the Unix Epoch (January 1 1970 00:00:00 GMT) and thetime specified. Arguments may be left out in order from right to left; any argumentsthus omitted will be set to the current value according to the localdate and time.

<?php
echo mktime(0, 0, 0, date("m"), date("d")-1, date("Y"));
?>

result: 1269820800

Step 3

Now merge all and look at this:

<?php
$yesterday = date("Y-m-d", mktime(0, 0, 0, date("m") , date("d")-1,date("Y")));
echo $yesterday;
?>

result: March 29, 2010

Operating similarly, it is possible to receive time hour back.

<?php
$yesterday = date("H:i:s",mktime(date("H"), 0, 0, date("m"),date("d"), date("Y")));
echo $yesterday;
?>

result: 20:00:00

or 7 days ago:

<?php
$week = date("Y-m-d",mktime(0, 0, 0, date("m"), date("d")-7,date("Y")));
echo $week;
?>

result: 2010-03-23

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

For me, I could only get it to work with

set serveroutput on format word_wrapped;

The wraped and WRAPPED just threw errors: SQLPLUS command failed - not enough arguments

location="(.*)" will match from the " after location= until the " after some="xxx unless you make it non-greedy. So you either need .*? (i.e. make it non-greedy) or better replace .* with [^"]*.

Can also use:

find . -mindepth 1 -mtime +3 -delete

To not delete target directory

The usual rules should apply for how you send the request. If the request is to retrieve information (e.g. a partial search 'hint' result, or a new page to be displayed, etc...) you can use GET. If the data being sent is part of a request to change something (update a database, delete a record, etc..) then use POST.

Server-side, there's no reason to use the raw input, unless you want to grab the entire post/get data block in a single go. You can retrieve the specific information you want via the _GET/_POST arrays as usual. AJAX libraries such as MooTools/jQuery will handle the hard part of doing the actual AJAX calls and encoding form data into appropriate formats for you.

Lazy fetching decides whether to load child objects while loading the Parent Object. You need to do this setting respective hibernate mapping file of the parent class. Lazy = true (means not to load child) By default the lazy loading of the child objects is true.

This make sure that the child objects are not loaded unless they are explicitly invoked in the application by calling getChild() method on parent.In this case hibernate issues a fresh database call to load the child when getChild() is actully called on the Parent object.

But in some cases you do need to load the child objects when parent is loaded. Just make the lazy=false and hibernate will load the child when parent is loaded from the database.

Example : If you have a TABLE ? EMPLOYEE mapped to Employee object and contains set of Address objects. Parent Class : Employee class, Child class : Address Class

public class Employee { 
private Set address = new HashSet(); // contains set of child Address objects 
public Set getAddress () { 
return address; 
} 
public void setAddresss(Set address) { 
this. address = address; 
} 
} 

In the Employee.hbm.xml file

<set name="address" inverse="true" cascade="delete" lazy="false"> 
<key column="a_id" /> 
<one-to-many class="beans Address"/> 
</set> 

In the above configuration. If lazy="false" : - when you load the Employee object that time child object Address is also loaded and set to setAddresss() method. If you call employee.getAdress() then loaded data returns.No fresh database call.

If lazy="true" :- This the default configuration. If you don?t mention then hibernate consider lazy=true. when you load the Employee object that time child object Adress is not loaded. You need extra call to data base to get address objects. If you call employee.getAdress() then that time database query fires and return results. Fresh database call.

Ten years later and using Python 3.7 and Linux there are still different ways to do this:

import subprocess
from pathlib import Path

#using pathlib.Path
path = Path('/path/to/your/dir')
subprocess.run(["rm", "-rf", str(path)])

#using strings
path = "/path/to/your/dir"
subprocess.run(["rm", "-rf", path])

Essentially it's using Python's subprocess module to run the bash script $ rm -rf '/path/to/your/dir as if you were using the terminal to accomplish the same task. It's not fully Python, but it gets it done.

The reason I included the pathlib.Path example is because in my experience it's very useful when dealing with many paths that change. The extra steps of importing the pathlib.Path module and converting the end results to strings is often a lower cost to me for development time. It would be convenient if Path.rmdir() came with an arg option to explicitly handle non-empty dirs.

I didn't mean to answer my own question but I just thought about running a sitemap generator. First one I found http://www.xml-sitemaps.com has a nice text output. Perfect for my needs.

Use the Linux Command Line

Use the command line, as described in this related question: How do I check if my SSL Certificate is SHA1 or SHA2 on the commandline.

Command

Here's the command. Replace www.yoursite.com:443 to fit your needs. Default SSL port is 443:

openssl s_client -connect www.yoursite.com:443 < /dev/null 2>/dev/null \
    | openssl x509 -text -in /dev/stdin | grep "Signature Algorithm"

Results

This should return something like this for the sha1:

Signature Algorithm: sha1WithRSAEncryption

or this for the newer version:

Signature Algorithm: sha256WithRSAEncryption

References

The article Why Google is Hurrying the Web to Kill SHA-1 describes exactly what you would expect and has a pretty graphic, too.

It is a trivial process. You can see a good example in the source code SMSPopup

Examine the following methods:

SmsMmsMessage getSmsDetails(Context context, long ignoreThreadId, boolean unreadOnly)
long findMessageId(Context context, long threadId, long _timestamp, int messageType
void setMessageRead(Context context, long messageId, int messageType)
void deleteMessage(Context context, long messageId, long threadId, int messageType)

this is the method for reading:

SmsMmsMessage getSmsDetails(Context context,
                            long ignoreThreadId, boolean unreadOnly)
{
   String SMS_READ_COLUMN = "read";

   String SORT_ORDER = "date DESC";
   int count = 0;
   // Log.v(WHERE_CONDITION);
   if (ignoreThreadId > 0) {
      // Log.v("Ignoring sms threadId = " + ignoreThreadId);
      WHERE_CONDITION += " AND thread_id != " + ignoreThreadId;
   }
   Cursor cursor = context.getContentResolver().query(
                      SMS_INBOX_CONTENT_URI,

      try {
         count = cursor.getCount();
         if (count > 0) {
            cursor.moveToFirst();
            // String[] columns = cursor.getColumnNames();

            // Log.v("columns " + i + ": " + columns[i] + ": " + cursor.getString(i));
            // }                                         
            long messageId = cursor.getLong(0);
            long threadId = cursor.getLong(1);

            long timestamp = cursor.getLong(4);

            String body = cursor.getString(5);

R.id.*, since ADT 14 are not more declared as final static int so you can not use in switch case construct. You could use if else clause instead.

Compatibility Supports Says that Under compatibility level 110, the default style for CAST and CONVERT operations on time and datetime2 data types is always 121. If your query relies on the old behavior, use a compatibility level less than 110, or explicitly specify the 0 style in the affected query.

That means by default datetime2 is CAST as varchar to 121 format. For ex; col1 and col2 formats (below) are same (other than the 0s at the end)

SELECT CONVERT(varchar, GETDATE(), 121) col1,
       CAST(convert(datetime2,GETDATE()) as varchar) col2,
       CAST(GETDATE() as varchar) col3

SQL FIDDLE DEMO

--Results
COL1                    | COL2                          | COL3
2013-02-08 09:53:56.223 | 2013-02-08 09:53:56.2230000   | Feb 8 2013 9:53AM

FYI, if you use CONVERT instead of CAST you can use a third parameter to specify certain formats as listed here on MSDN

you could also change from the .get() method to the .getJSON() method, jQuery will then parse the string returned as data to a javascript object and/or array that you can then reference like any other javascript object/array.

using your code above, if you changed .get to .getJSON, you should get an alert of [object Object] for each element in the array. If you changed the alert to alert(item.name) you will get the names.

With the recent update to melt.data.table, we can now melt multiple columns. With that, we can do:

require(data.table) ## 1.9.5
melt(setDT(df), id=1:2, measure=patterns("^Q3.2", "^Q3.3"), 
     value.name=c("Q3.2", "Q3.3"), variable.name="loop_number")
 #    id       time loop_number         Q3.2        Q3.3
 # 1:  1 2009-01-01           1 -0.433978480  0.41227209

You can get the development version from here.

assertTrue will fail if the second parameter evaluates to false (in other words, it ensures that the value is true). assertFalse does the opposite.

assertTrue("This will succeed.", true);
assertTrue("This will fail!", false);

assertFalse("This will succeed.", false);
assertFalse("This will fail!", true);

As with many other things, the best way to become familiar with these methods is to just experiment :-).

You could also use boost, which defines important math constants with maximum accuracy for the requested type (i.e. float vs double).

const double pi = boost::math::constants::pi<double>();

Check out the boost documentation for more examples.

I faced the same problem about 2 days ago when I had to convert a 20GB+ MySQL database to SQLite. It was by no means an easy task and I ended up writing this Python package that does the job.

The upside of it being written in Python is that it's cross platform (unlike a shell/bash script) and can all be easily installed using pip install (even on Windows). It uses generators and chunking of the data being processed and is therefore very memory efficient.

I also put in some effort to correctly translate most of the datatypes from MySQL to SQLite.

The tool is also thoroughly tested and works on Python 2.7 and 3.5+.

It is invokable via command line but can also be used as a standard Python class which you can include in some larger Python orchestration.

Here's how you use it:

Usage: mysql2sqlite [OPTIONS]

Options:
  -f, --sqlite-file PATH     SQLite3 database file  [required]
  -d, --mysql-database TEXT  MySQL database name  [required]
  -u, --mysql-user TEXT      MySQL user  [required]
  -p, --mysql-password TEXT  MySQL password
  -h, --mysql-host TEXT      MySQL host. Defaults to localhost.
  -P, --mysql-port INTEGER   MySQL port. Defaults to 3306.
  -c, --chunk INTEGER        Chunk reading/writing SQL records
  -l, --log-file PATH        Log file
  -V, --vacuum               Use the VACUUM command to rebuild the SQLite
                             database file, repacking it into a minimal amount
                             of disk space
  --use-buffered-cursors     Use MySQLCursorBuffered for reading the MySQL
                             database. This can be useful in situations where
                             multiple queries, with small result sets, need to
                             be combined or computed with each other.
  --help                     Show this message and exit.

use Jackson (https://github.com/FasterXML/jackson) from http://json.org/

HashMap<String,Object> result =
       new ObjectMapper().readValue(<JSON_OBJECT>, HashMap.class);

These functions are fairly compact and only use standard Python 2.6 and later.

def ddhhmmss(seconds):
    """Convert seconds to a time string "[[[DD:]HH:]MM:]SS".
    """
    dhms = ''
    for scale in 86400, 3600, 60:
        result, seconds = divmod(seconds, scale)
        if dhms != '' or result > 0:
            dhms += '{0:02d}:'.format(result)
    dhms += '{0:02d}'.format(seconds)
    return dhms


def seconds(dhms):
    """Convert a time string "[[[DD:]HH:]MM:]SS" to seconds.
    """
    components = [int(i) for i in dhms.split(':')]
    pad = 4 - len(components)
    if pad < 0:
        raise ValueError('Too many components to match [[[DD:]HH:]MM:]SS')
    components = [0] * pad + components
    return sum(i * j for i, j in zip((86400, 3600, 60, 1), components))

And here are tests to go with them. I'm using the pytest package as a simple way to test exceptions.

import ddhhmmss

import pytest


def test_ddhhmmss():
    assert ddhhmmss.ddhhmmss(0) == '00'
    assert ddhhmmss.ddhhmmss(2) == '02'

Your query will work in MYSQL if you set to disable ONLY_FULL_GROUP_BY server mode (and by default It is). But in this case, you are using different RDBMS. So to make your query work, add all non-aggregated columns to your GROUP BY clause, eg

SELECT col1, col2, SUM(col3) totalSUM
FROM tableName
GROUP BY col1, col2

Non-Aggregated columns means the column is not pass into aggregated functions like SUM, MAX, COUNT, etc..

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

Try the Join-Path cmdlet:

Get-ChildItem c:\code\*\bin\* -Filter *.dll | Foreach-Object {
    Join-Path -Path  $_.DirectoryName -ChildPath "$buildconfig\$($_.Name)" 
}

Have a look at the examples below for a clearer understanding of the differences between the different operators:

> # Floating Division:
> 5/2
[1] 2.5
> 
> # Integer Division:
> 5%/%2
[1] 2
> 
> # Remainder:
> 5%%2
[1] 1

Write a:hover::before instead of a::before:hover: example.

Try UISegmentedControl. It behaves similarly to radio buttons -- presents an array of choices and lets the user pick 1.

The best solution I could find for this problem is to specify private key file in ansible.cfg (I usually keep it in the same folder as a playbook):

[defaults]
inventory=ec2.py
vault_password_file = ~/.vault_pass.txt
host_key_checking = False
private_key_file = /Users/eric/.ssh/secret_key_rsa

Though, it still sets private key globally for all hosts in playbook.

Note: You have to specify full path to the key file - ~user/.ssh/some_key_rsa silently ignored.

To make a dropdown list you need two properties:

1. a property to which you will bind to (usually a scalar property of type integer or string)
2. a list of items containing two properties (one for the values and one for the text)

In your case you only have a list of string which cannot be exploited to create a usable drop down list.

While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:

@model List<string>
@Html.DropDownList(
    "Foo", 
    new SelectList(
        Model.Select(x => new { Value = x, Text = x }),
        "Value",
        "Text"
    )
)

where Foo will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:

<select name="Foo" id="Foo">
    <option value="item 1">item 1</option>
    <option value="item 2">item 2</option>
    <option value="item 3">item 3</option>
    ...
</select>

This being said a far better view model for a drop down list is the following:

public class MyListModel
{
    public string SelectedItemId { get; set; }
    public IEnumerable<SelectListItem> Items { get; set; }
}

and then:

@model MyListModel
@Html.DropDownListFor(
    x => x.SelectedItemId,
    new SelectList(Model.Items, "Value", "Text")
)

and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId property of this view model to the corresponding Value of some element in the Items collection.

Other answers are great. This is another way it can be done.

1. Here I use SizedBox.expand() to fill available space and for passing tight constraints for its children (Container).
2. BoxFit.cover enum to Zoom the image and cover whole screen

 Widget build(BuildContext context) {
    return Scaffold(
      body: SizedBox.expand( // -> 01
        child: Container(
          decoration: BoxDecoration(
            image: DecorationImage(
              image: NetworkImage('https://flutter.github.io/assets-for-api-docs/assets/widgets/owl-2.jpg'),
              fit: BoxFit.cover,    // -> 02
            ),
          ),
        ),
      ),
    );
  }

You should pass @item.email in quotes then it will be treated as string argument

<td><a href ="#"  onclick="Getinfo('@item.email');" >6/16/2016 2:02:29 AM</a>  </td>

Otherwise, it is treated as variable thus error is generated.

I created it a long time ago, related question

String.Format = function (b) {
    var a = arguments;
    return b.replace(/(\{\{\d\}\}|\{\d\})/g, function (b) {
        if (b.substring(0, 2) == "{{") return b;
        var c = parseInt(b.match(/\d/)[0]);
        return a[c + 1]
    })
};

select * into newtable from oldtable

use ondragstart(event) instead of ondrag(event)

I would prevent loops in general if i can, set approaches are much more efficient:

INSERT INTO tblFoo
  SELECT TOP (300) n = ROW_NUMBER()OVER (ORDER BY [object_id]) 
  FROM sys.all_objects ORDER BY n;

You may use Request.Cookies collection to read the cookies.

if(Request.Cookies["key"]!=null)
{
   var value=Request.Cookies["key"].Value;
}

After some time with Google I asked on the ask ubuntu chat room.

A user there was king enough to help me find the solution I was looking for and i wanted to share so that any following suers running into this may find it:

grep -P "(^|\s)abc(\s|$)" gives the result I was looking for. -P is an experimental implementation of perl regexps.

grepping for abc and then using filters like grep -v '@abc' (this is far from perfect...) should also work, but my patch does something similar.

Here is a working example: http://jsfiddle.net/rVBzt/ (using jQuery)

<img id="tiger" src="https://twimg0-a.akamaihd.net/profile_images/2642324404/46d743534606515238a9a12cfb4b264a.jpeg">

<a id="toggle">click to toggle</a>

img {display: none;}

a {cursor: pointer; color: blue;}

$('#toggle').click(function() {
    $('#tiger').toggle();
});

This answer may be late reply but it will be useful for seeing this topic in future.

The features of .NET framework 4.5 can be seen in the following link.

To summarize:

• Installation

  .NET Framework 4.5 does not support Windows XP or Windows Server 2003, and therefore, if you have to create applications that target these operating systems, you will need to stay with .NET Framework 4.0. In contrast, Windows 8 and Windows Server 2012 in all of their editions include .NET Framework 4.5.

• Support for Arrays Larger than 2 GB on 64-bit Platforms
• Enhanced Background Server Garbage Collection
• Support for Timeouts in Regular Expression Evaluations
• Support for Unicode 6.0.0 in Culture-Sensitive Sorting and Casing Rules on Windows 8
• Simple Default Culture Definition for an Application Domain
• Internationalized Domain Names in Windows 8 Apps

So, there are three parts. Reading, storing and sending.

Here's the reading part:

var fs = require('fs');

function readFiles(dirname, onFileContent, onError) {
  fs.readdir(dirname, function(err, filenames) {
    if (err) {
      onError(err);
      return;
    }
    filenames.forEach(function(filename) {
      fs.readFile(dirname + filename, 'utf-8', function(err, content) {
        if (err) {
          onError(err);
          return;
        }
        onFileContent(filename, content);
      });
    });
  });
}

Here's the storing part:

var data = {};
readFiles('dirname/', function(filename, content) {
  data[filename] = content;
}, function(err) {
  throw err;
});

The sending part is up to you. You may want to send them one by one or after reading completion.

If you want to send files after reading completion you should either use sync versions of fs functions or use promises. Async callbacks is not a good style.

Additionally you asked about stripping an extension. You should proceed with questions one by one. Nobody will write a complete solution just for you.

Instead of nohup, you should use screen. It achieves the same result - your commands are running "detached". However, you can resume screen sessions and get back into their "hidden" terminal and see recent progress inside that terminal.

screen has a lot of options. Most often I use these:

To start first screen session or to take over of most recent detached one:

screen -Rd 

To detach from current session: Ctrl+ACtrl+D

You can also start multiple screens - read the docs.

There are many questions on that and many suggestions. None of them helped me for the recent Opencv 3.4.16 and Python 3.6/3.7. Finally I switched to Pyhon 2.7.15 and installed opencv 3.1.0. The DLL-problem was solved.

When I look in cv2.pyd with dependency walker, the 3.1 has no dependency to one missing dll. Opencv 3.4 has this missing dependency to this dll:

API-MS-WIN-DOWNLEVEL-SHLWAPI-L1-1-0.DLL

may be this is the problem.

P.S.: I have Win7 pofessional 64Bit, 32Bit Python 2.7.15

if anyone faced problem even after using return false; . then use the below.

setTimeout(function(){document.location.href = "index.php"},500);

For Safari 12 and later, you can try the JSONBeautifier bookmarklet. Also works with other browsers.

I created this because JSON Formatter for Safari stopped working in Safari 12. There are a few new options for Safari 12, but I didn't find an open source one in the App Store, and I do not trust closed source browser extensions.

This can be used as a bookmarklet or the source, json-beautifier.js, can be copied and pasted into the browser console. The code is freely available for review and is less than 100 lines of code including comments. Runs entirely on your device and never sends your data over a network.

Works with local files too.

Reference Maven error "Failure to transfer..."

find ~/.m2  -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;

array_values() will do pretty much what you want:

$numeric_indexed_array = array_values($your_array);
// $numeric_indexed_array = array('bar', 'bin', 'ipsum');
print($numeric_indexed_array[0]); // bar

I have the following approaches

object HelloV2 {

   def main(args: Array[String]) {

     //Efficient iteration with index in Scala

     //Approach #1
     var msg = "";

     for (i <- args.indices)
     {
       msg+=(args(i));
     }
     var msg1="";

     //Approach #2
     for (i <- 0 until args.length) 
     {
       msg1 += (args(i));
     }

     //Approach #3
     var msg3=""
     args.foreach{
       arg =>
        msg3 += (arg)
     }


      println("msg= " + msg);

      println("msg1= " + msg1);

      println("msg3= " + msg3);

   }
}

In my case it was because of function inside another function! once I moved out the function, error was gone , and everything worked as expected.

This answer explains why you shouldn't use function inside function.

This might help somebody.

Working on the same idea as above , but generalizing a bit . Since the backspace should work fine on the input elements , but should not work if the focus is a paragraph or something , since it is there where the page tends to go back to the previous page in history .

$('html').on('keydown' , function(event) {

        if(! $(event.target).is('input')) {
            console.log(event.which);
           //event.preventDefault();
           if(event.which == 8) {
            //  alert('backspace pressed');
            return false;
         }
        }
});

returning false => both event.preventDefault and event.stopPropagation are in effect .

You're looking for the DataSource property:

List<SomeType> someList = ...;
myListBox.DataSource = someList;

You should also set the DisplayMember property to the name of a property in the object that you want the listbox to display. If you don't, it will call ToString().

A not well known feature of numpy is to use r_. This is a simple way to build up arrays quickly:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.r_[a[None,:],b[None,:]]
print(c)
#[[1 2 3]
# [4 5 6]]

The purpose of a[None,:] is to add an axis to array a.

In addition to previous answers, you should be aware that there are strange behaviours associated with -0.0f and +0.0f (they are == but not equals) and Float.NaN (it is equals but not ==) (hope I've got that right - argh, don't do it!).

Edit: Let's check!

import static java.lang.Float.NaN;
public class Fl {
    public static void main(String[] args) {
        System.err.println(          -0.0f   ==              0.0f);   // true
        System.err.println(new Float(-0.0f).equals(new Float(0.0f))); // false
        System.err.println(            NaN   ==               NaN);   // false
        System.err.println(new Float(  NaN).equals(new Float( NaN))); // true
    }
} 

Welcome to IEEE/754.

ASP.NET Core

Routing is configured in the Configure method of the Startup class. To set the "homepage" simply add the following. This will cause users to be routed to the controller and action defined in the MapRoute method when/if they navigate to your site’s base URL, i.e., yoursite.com will route users to yoursite.com/foo/index:

app.UseMvc(routes =>
{
   routes.MapRoute(
   name: "default",
   template: "{controller=FooController}/{action=Index}/{id?}");
});

Pre-ASP.NET Core

Use the RegisterRoutes method located in either App_Start/RouteConfig.cs (MVC 3 and 4) or Global.asax.cs (MVC 1 and 2) as shown below. This will cause users to be routed to the controller and action defined in the MapRoute method if they navigate to your site’s base URL, i.e., yoursite.com will route the user to yoursite.com/foo/index:

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    // Here I have created a custom "Default" route that will route users to the "YourAction" method within the "FooController" controller.
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "FooController", action = "Index", id = UrlParameter.Optional }
    );
}

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

I needed to know this and came here, before I remembered the Environment class.

In case anyone else had this issue, just use this: Environment.CurrentDirectory.

Example:

Dim dataDirectory As String = String.Format("{0}\Data\", Environment.CurrentDirectory)

When run from Visual Studio in debug mode yeilds:

C:\Development\solution folder\application folder\bin\debug

This is the exact behaviour I needed, and its simple and straightforward enough.

This would work

setInterval(function(){$("#myButtonId").click();}, 1000);

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

You are not evaluating a condition for the IF. I am guessing you want to not copy if you find stringToCheck in fileToCheck. You need to do something like (code untested but you get the idea):

CD C:\MyFolder
findstr /c:"stringToCheck" fileToCheck.bat
IF NOT ERRORLEVEL 0 XCOPY "C:\OtherFolder\fileToCheck.bat" "C:\MyFolder" /s /y

EDIT by dbenham
The above test is WRONG, it always evaluates to FALSE.
The correct test is IF ERRORLEVEL 1 XCOPY ...

Update: I can't test the code, but I am not sure what return value findstr actually returns if it doesn't find anything. You might have to do something like:

CD C:\MyFolder
findstr /c:"stringToCheck" fileToCheck.bat > tempfindoutput.txt
set /p FINDOUTPUT= < tempfindoutput.txt
IF "%FINDOUTPUT%"=="" XCOPY "C:\OtherFolder\fileToCheck.bat" "C:\MyFolder" /s /y
del tempfindoutput.txt

The best thing hands down that I have tried is LINQ to XSD (which is unknown to most developers). You give it an XSD Schema and it generates a perfectly mapped complete strongly-typed object model (based on LINQ to XML) for you in the background, which is really easy to work with - and it updates and validates your object model and XML in real-time. While it's still "Preview", I have not encountered any bugs with it.

If you have an XSD Schema that looks like this:

  <xs:element name="RootElement">
     <xs:complexType>
      <xs:sequence>
        <xs:element name="Element1" type="xs:string" />
        <xs:element name="Element2" type="xs:string" />
      </xs:sequence>
       <xs:attribute name="Attribute1" type="xs:integer" use="optional" />
       <xs:attribute name="Attribute2" type="xs:boolean" use="required" />
     </xs:complexType>
  </xs:element>

Then you can simply build XML like this:

RootElement rootElement = new RootElement;
rootElement.Element1 = "Element1";
rootElement.Element2 = "Element2";
rootElement.Attribute1 = 5;
rootElement.Attribute2 = true;

Or simply load an XML from file like this:

RootElement rootElement = RootElement.Load(filePath);

Or save it like this:

rootElement.Save(string);
rootElement.Save(textWriter);
rootElement.Save(xmlWriter);

rootElement.Untyped also yields the element in form of a XElement (from LINQ to XML).

Based on Michael Scharf's comment:

You can leave out the password so that it won't be logged in your Bash history file:

git clone https://[email protected]/username/repository.git

It will prompt you for your password.

Alternatively, you may use:

git clone https://username:[email protected]/username/repository.git

This way worked for me from a GitHub repository.

protocol CustomError : Error {

    var localizedTitle: String
    var localizedDescription: String

}

I find the most valuable feature of .FormulaR1C1 is sheer speed. Versus eg a couple of very large loops filling some data into a sheet, If you can convert what you are doing into a .FormulaR1C1 form. Then a single operation eg myrange.FormulaR1C1 = "my particular formuala" is blindingly fast (can be a thousand times faster). No looping and counting - just fill the range at high speed.

Faced to this issue after a long time since question asked here. when checking material-ui code I found it's now accessible through inputRef property.

...
<CssTextField
  inputRef={(c) => {this.myRefs.username = c}}
  label="Username"
  placeholder="xxxxxxx"
  margin="normal"
  className={classes.textField}
  variant="outlined"
  fullWidth
/>
...

Then Access value like this.

  onSaveUser = () => {
    console.log('Saving user');
    console.log(this.myRefs.username.value);
  }

You need to wrap the table inside another element and set the height of that element. Example with inline css:

<div style="height: 500px; overflow: auto;">
 <table>
 </table>
</div>

C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG

Does this help you:

<script type="text/javascript">
window.onerror = function() {
    alert("Error caught");
};

xxx();
</script>

I'm not sure how it handles Flash errors though...

Update: it doesn't work in Opera, but I'm hacking Dragonfly right now to see what it gets. Suggestion about hacking Dragonfly came from this question:

Mimic Window. onerror in Opera using javascript

If you use it on normal html tags, it means that you can programatically manipulate them in event handlers etc, eg change the href or class of an anchor tag on page load... only do that if you have to, because vanilla html tags go faster.

As far as user controls and server controls, no, they just wont work without them, without having delved into the innards of the aspx preprocessor, couldn't say exactly why, but would take a guess that for probably good reasons, they just wrote the parser that way, looking for things explicitly marked as "do something".

If @JonSkeet is around anywhere, he will probably be able to provide a much better answer.

You are using an inline table value function. Therefore you must use Select * From function. If you want to use select function() you must use a scalar function.

https://msdn.microsoft.com/fr-fr/library/ms186755%28v=sql.120%29.aspx

Use defaultInputValue props like so:

<Select
   name="name"
   isClearable
   onChange={handleChanges}
   options={colourOptions}
   isSearchable="true"
   placeholder="Brand Name"
   defaultInputValue="defaultInputValue"
/>

Named aggregations with pandas >= 0.25.0

Since pandas version 0.25.0 we have named aggregations where we can groupby, aggregate and at the same time assign new names to our columns. This way we won't get the MultiIndex columns, and the column names make more sense given the data they contain:

aggregate and get a list of strings

grp = df.groupby('A').agg(B_sum=('B','sum'),
                          C=('C', list)).reset_index()

print(grp)
   A     B_sum               C
0  1  1.615586  [This, string]

aggregate and join the strings

Usign fs with node.

var fs = require('fs');

try {  
    var data = fs.readFileSync('file.txt', 'utf8');
    console.log(data.toString());    
} catch(e) {
    console.log('Error:', e.stack);
}

Use Date::toLocaleDateString.

new Date().toLocaleDateString()
= "9/13/2015"

You don't need to set innerHTML, just by writing

<p>
<script> document.write(new Date().toLocaleDateString()); </script>
</p>

will work.

P.S.

new Date().toDateString()
= "Sun Sep 13 2015"

both @Reno and @Vinayak B answers together if you want to hide the keyboard after the action

textView.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH || actionId == EditorInfo.IME_ACTION_DONE) {
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(textView.getWindowToken(), 0);
            return true;
        }
        return false;
    }
});

textView.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
             // your action here
        }
    }
});

This question explicitly mentions Bash, but if you happen to have ZSH available it is pretty simple:

zmv '(*).*' '$1.txt'

If you get zsh: command not found: zmv then simply run:

autoload -U zmv

And then try again.

Thanks to this original article for the tip about zmv.

Use jQuery.one()

Attach a handler to an event for the elements. The handler is executed at most once per element per event type

$('form').one('submit', function(e) {
    e.preventDefault();
    // do your things ...

    // and when you done:
    $(this).submit();
});

The use of one prevent also infinite loop because this custom submit event is detatched after the first submit.

A better solution would be using Kendo ui draw dom to export to pdf-

Suppose the following html file which contains the canvas tag:

<script src="http://kendo.cdn.telerik.com/2017.2.621/js/kendo.all.min.js"></script>

    <script type="x/kendo-template" id="page-template">
     <div class="page-template">
            <div class="header">

            </div>
            <div class="footer" style="text-align: center">

                <h2> #:pageNum# </h2>
            </div>
      </div>
    </script>
    <canvas id="myCanvas" width="500" height="500"></canvas>
    <button onclick="ExportPdf()">download</button>

Now after that in your script write down the following and it will be done:

function ExportPdf(){ 
kendo.drawing
    .drawDOM("#myCanvas", 
    { 
        forcePageBreak: ".page-break", 
        paperSize: "A4",
        margin: { top: "1cm", bottom: "1cm" },
        scale: 0.8,
        height: 500, 
        template: $("#page-template").html(),
        keepTogether: ".prevent-split"
    })
        .then(function(group){
        kendo.drawing.pdf.saveAs(group, "Exported_Itinerary.pdf")
    });
}

And that is it, Write anything in that canvas and simply press that download button all exported into PDF. Here is a link to Kendo UI - http://docs.telerik.com/kendo-ui/framework/drawing/drawing-dom And a blog to better understand the whole process - https://www.cronj.com/blog/export-htmlcss-pdf-using-javascript/

You can simplify the code by introducing an extra variable.

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

int main()
{
    char str[100], *s = str, *t = NULL;

    strcpy(str, "a space delimited string");
    while ((t = strtok(s, " ")) != NULL) {
        s = NULL;
        printf(":%s:\n", t);
    }
    return 0;
}

You can change the mysql root password by logging in to the database directly (mysql -h your_host -u root) then run

SET PASSWORD FOR root@localhost = PASSWORD('yourpassword');

Best Solution

Create one simple FileUtil class & use to create, copy and rename the file

I used uri.toString() and uri.getPath() but not work for me. I finally found this solution.

import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.provider.OpenableColumns;
import android.util.Log;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class FileUtil {
    private static final int EOF = -1;
    private static final int DEFAULT_BUFFER_SIZE = 1024 * 4;

    private FileUtil() {

    }

    public static File from(Context context, Uri uri) throws IOException {
        InputStream inputStream = context.getContentResolver().openInputStream(uri);
        String fileName = getFileName(context, uri);
        String[] splitName = splitFileName(fileName);
        File tempFile = File.createTempFile(splitName[0], splitName[1]);
        tempFile = rename(tempFile, fileName);
        tempFile.deleteOnExit();
        FileOutputStream out = null;
        try {
            out = new FileOutputStream(tempFile);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        if (inputStream != null) {
            copy(inputStream, out);
            inputStream.close();
        }

        if (out != null) {
            out.close();
        }
        return tempFile;
    }

    private static String[] splitFileName(String fileName) {
        String name = fileName;
        String extension = "";
        int i = fileName.lastIndexOf(".");
        if (i != -1) {
            name = fileName.substring(0, i);
            extension = fileName.substring(i);
        }

        return new String[]{name, extension};
    }

    private static String getFileName(Context context, Uri uri) {
        String result = null;
        if (uri.getScheme().equals("content")) {
            Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
            try {
                if (cursor != null && cursor.moveToFirst()) {
                    result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
                }
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if (cursor != null) {
                    cursor.close();
                }
            }
        }
        if (result == null) {
            result = uri.getPath();
            int cut = result.lastIndexOf(File.separator);
            if (cut != -1) {
                result = result.substring(cut + 1);
            }
        }
        return result;
    }

    private static File rename(File file, String newName) {
        File newFile = new File(file.getParent(), newName);
        if (!newFile.equals(file)) {
            if (newFile.exists() && newFile.delete()) {
                Log.d("FileUtil", "Delete old " + newName + " file");
            }
            if (file.renameTo(newFile)) {
                Log.d("FileUtil", "Rename file to " + newName);
            }
        }
        return newFile;
    }

    private static long copy(InputStream input, OutputStream output) throws IOException {
        long count = 0;
        int n;
        byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
        while (EOF != (n = input.read(buffer))) {
            output.write(buffer, 0, n);
            count += n;
        }
        return count;
    }
}

Use FileUtil class in your code

try {
         File file = FileUtil.from(MainActivity.this,fileUri);
         Log.d("file", "File...:::: uti - "+file .getPath()+" file -" + file + " : " + file .exists());

  } catch (IOException e) {
          e.printStackTrace();
  }

Unfortunately, vars files do not have include statements.

You can either put all the vars into the definitions dictionary, or add the variables as another dictionary in the same file.

If you don't want to have them in the same file, you can include them at the playbook level by adding the vars file at the start of the play:

---
- hosts: myhosts

  vars_files:
    - default_step.yml

or in a task:

---
- hosts: myhosts

  tasks:
    - name: include default step variables
      include_vars: default_step.yml

The reason "sign" is not included is that if we included every useful one-liner in the list of built-in functions, Python wouldn't be easy and practical to work with anymore. If you use this function so often then why don't you do factor it out yourself? It's not like it's remotely hard or even tedious to do so.

Simply, to enforce JAVA version to Ant in Eclipse:

Use RunAs option on Ant file then select External Tool Configuration in JRE tab define your JDK/JRE version you want to use.

LEFT is not a function in Oracle. This probably came from someone familiar with SQL Server:

Returns the left part of a character string with the specified number of characters.

-- Syntax for SQL Server, Azure SQL Database, Azure SQL Data Warehouse, Parallel Data Warehouse  
LEFT ( character_expression , integer_expression )  

The % operator is for integers. You're looking for the fmod() function.

#include <cmath>

int main()
{
    double x = 6.3;
    double y = 2.0;
    double z = std::fmod(x,y);

}

Use the Format function.

Format(Date, "yyyy-mm-dd hh:MM:ss")

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

#libraries to include

import os
from flask import request, jsonify
from app import app, mongo
import logger
ROOT_PATH = os.environ.get('ROOT_PATH')<br>
@app.route('/get/questions/', methods=['GET', 'POST','DELETE', 'PATCH'])
    def question():
    # request.args is to get urls arguments 


    if request.method == 'GET':
        start = request.args.get('start', default=0, type=int)
        limit_url = request.args.get('limit', default=20, type=int)
        questions = mongo.db.questions.find().limit(limit_url).skip(start);
        data = [doc for doc in questions]
        return jsonify(isError= False,
                    message= "Success",
                    statusCode= 200,
                    data= data), 200

# request.form to get form parameter

    if request.method == 'POST':
        average_time = request.form.get('average_time')
        choices = request.form.get('choices')
        created_by = request.form.get('created_by')
        difficulty_level = request.form.get('difficulty_level')
        question = request.form.get('question')
        topics = request.form.get('topics')

    ##Do something like insert in DB or Render somewhere etc. it's up to you....... :)
