Programs & Examples On #Wrapper

You can use

jQuery(document).ready(function(){ ...... });

or

(function ($) { ...... }(jQuery));

As well for correctness of using == you can just unbox one of compared Integer values before doing == comparison, like:

if ( firstInteger.intValue() == secondInteger ) {..

The second will be auto unboxed (of course you have to check for nulls first).

Looks it's one of the early asked question about Golang . And same time answers to never update . During these three to four years , too many new libraries and blog post has been out . Below are the few links what I felt useful .

Just what it sounds like: a class that "wraps" the functionality of another class or API in a simpler or merely different API.

See: Adapter pattern, Facade pattern

If you want to refer to a nested table by multiple keys you can just assign them to separate keys. The tables are not duplicated, and still reference the same values.

arr = {}
apples = {'a', "red", 5 }
arr.apples = apples
arr[1] = apples

This code block lets you iterate through all the key-value pairs in a table (http://lua-users.org/wiki/TablesTutorial):

for k,v in pairs(t) do
 print(k,v)
end

I fixed this issue by using Product > Clean Build Folder (CommandShiftK), which makes a new clean build, really odd.

Strange behavior with MS Excel: If i export to "text based, comma-separated format (csv)" this is the mime-type I get after uploading on my webserver:

[name] => data.csv
[type] => application/vnd.ms-excel

So Microsoft seems to be doing own things again, regardless of existing standards: https://en.wikipedia.org/wiki/Comma-separated_values

You could try some sort of COALESCE trick, eg:

SELECT COALESCE(
  CASE WHEN condition1 THEN calculation1 ELSE NULL END,
  CASE WHEN condition2 THEN calculation2 ELSE NULL END,
  etc...
)

myClub.distance = Console.ReadLine();

should be

myClub.mydistance = Console.ReadLine(); 

use your public properties that you have defined for others as well instead of the protected field members.

Just subtract the string address from what strchr returns:

char *string = "qwerty";
char *e;
int index;

e = strchr(string, 'e');
index = (int)(e - string);

Note that the result is zero based, so in above example it will be 2.

Internet Explorer specific, but rather good:

http://pamie.sourceforge.net/

The advantage compared to urllib/BeautifulSoup is that it executes Javascript as well since it uses IE.

Use isset()

$matchFound = (isset($_GET["id"]) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';

EDIT: This is added for the completeness sake. $_GET in php is a reserved variable that is an associative array. Hence, you could also make use of 'array_key_exists(mixed $key, array $array)'. It will return a boolean that the key is found or not. So, the following also will be okay.

$matchFound = (array_key_exists("id", $_GET)) && trim($_GET["id"]) == 'link1');
$slide = $matchFound ? trim($_GET["id"]) : '';

Don't worry about any performance differences, they're going to be minimal in this case normally.

Method 2 is preferable because

1. it doesn't require mutating a collection that exists outside the lambda expression,

2. it's more readable because the different steps that are performed in the collection pipeline are written sequentially: first a filter operation, then a map operation, then collecting the result (for more info on the benefits of collection pipelines, see Martin Fowler's excellent article),

3. you can easily change the way values are collected by replacing the Collector that is used. In some cases you may need to write your own Collector, but then the benefit is that you can easily reuse that.

As it was mentioned above CasperJS is the best tool to fill and send forms. Simplest possible example of how to fill & submit form using fill() function:

casper.start("http://example.com/login", function() {
//searches and fills the form with id="loginForm"
  this.fill('form#loginForm', {
    'login':    'admin',
    'password':    '12345678'
   }, true);
  this.evaluate(function(){
    //trigger click event on submit button
    document.querySelector('input[type="submit"]').click();
  });
});

#include <iostream>
#include <sstream>

std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;

while(std::getline(ss, token, ',')) {
    std::cout << token << '\n';
}

abc
def
ghi

You can use display: inline-block.

1. Goto your AndroidManifest.xml file.

2. Place your cursor in the package name like shown below. Don't select it, just place it.

   

3. Then press Shift + F6 you will get a popup window as shown below select Rename package.

   

4. Enter your new name and select Refactor. (Note since my cursor is on "something", only something is renamed.)

That's it done.

I have this folder structure:

D:\JavaProjects\OlivePressApp\com\lynda\olivepress\Main.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\press\OlivePress.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\olives\Kalamata.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\olives\Ligurian.class D:\JavaProjects\OlivePressApp\com\lynda\olivepress\olives\Olive.class

Main.class is in package com.lynda.olivepress

There are two other packages:

com.lynda.olivepress.press

com.lynda.olivepress.olive

1) Create a file named "Manifest.txt" with Two Lines, First with Main-Class and a Second Empty Line.

Main-Class: com.lynda.olivepress.Main

D:\JavaProjects\OlivePressApp\ Manifest.txt

2) Create JAR with Manifest and Main-Class Entry Point

D:\JavaProjects\OlivePressApp>jar cfm OlivePressApp.jar Manifest.txt com/lynda/olivepress/Main.class com/lynda/olivepress/*

3) Run JAR

java -jar OlivePressApp.jar

Note: com/lynda/olivepress/* means including the other two packages mentioned above, before point 1)

Best way is using BoxDecoration()

Advantage

• You can set border of widget
• You can set border Color or Width
• You can set Rounded corner of border
• You can add Shadow of widget

Disadvantage

• BoxDecoration only use with Container widget so you want to wrap your widget in Container()
  
  

Example

    Container(
      margin: EdgeInsets.all(10),
      padding: EdgeInsets.all(10),
      alignment: Alignment.center,
      decoration: BoxDecoration(
        color: Colors.orange,
        border: Border.all(
            color: Colors.pink[800],// set border color
            width: 3.0),   // set border width
        borderRadius: BorderRadius.all(
            Radius.circular(10.0)), // set rounded corner radius
        boxShadow: [BoxShadow(blurRadius: 10,color: Colors.black,offset: Offset(1,3))]// make rounded corner of border
      ),
      child: Text("My demo styling"),
    )

private void btnEnter_Click(object sender, EventArgs e)
{
    maskedTextBox1.Mask = "00/00/0000";
    maskedTextBox1.ValidatingType = typeof(System.DateTime);
    //if (!IsValidDOB(maskedTextBox1.Text)) 
    if (!ValidateBirthday(maskedTextBox1.Text))
        MessageBox.Show(" Not Valid");
    else
        MessageBox.Show("Valid");
}
// check date format dd/mm/yyyy. but not if year < 1 or > 2013.
public static bool IsValidDOB(string dob)
{ 
    DateTime temp;
    if (DateTime.TryParse(dob, out temp))
        return (true);
    else 
        return (false);
}
// checks date format dd/mm/yyyy and year > 1900!.
protected bool ValidateBirthday(String date)
{
    DateTime Temp;
    if (DateTime.TryParse(date, out Temp) == true &&
        Temp.Year > 1900 &&
       // Temp.Hour == 0 && Temp.Minute == 0 &&
        //Temp.Second == 0 && Temp.Millisecond == 0 &&
        Temp > DateTime.MinValue)
        return (true);
    else
        return (false);
}

Stop this error you have to follow this simple steps

1. Open Visual Studio
2. Select option debug from the top
3. Select Options
4. In Option Select debugging under debugging select General
5. In General Select check box "Automatically close the console when debugging stop"
6. Save it

Then Run the code by using Shortcut key Ctrl+f5

**Other wise it still show error when you run it direct

For child-parent communication you should pass a function setting the state from parent to child, like this

class Parent extends React.Component {_x000D_
  constructor(props) {_x000D_
    super(props)_x000D_
_x000D_
    this.handler = this.handler.bind(this)_x000D_
  }_x000D_
_x000D_
  handler() {_x000D_
    this.setState({_x000D_
      someVar: 'some value'_x000D_
    })_x000D_
  }_x000D_
_x000D_
  render() {_x000D_
    return <Child handler = {this.handler} />_x000D_
  }_x000D_
}_x000D_
_x000D_
class Child extends React.Component {_x000D_
  render() {_x000D_
    return <Button onClick = {this.props.handler}/ >_x000D_
  }_x000D_
}

This way the child can update the parent's state with the call of a function passed with props.

But you will have to rethink your components' structure, because as I understand components 5 and 3 are not related.

One possible solution is to wrap them in a higher level component which will contain the state of both component 1 and 3. This component will set the lower level state through props.

Perhaps a nice idiom for declaring constants for a class in Swift is to just use a struct named MyClassConstants like the following.

struct MyClassConstants{
    static let testStr = "test"
    static let testStrLength = countElements(testStr)

    static let arrayOfTests: [String] = ["foo", "bar", testStr]
}

In this way your constants will be scoped within a declared construct instead of floating around globally.

Update

I've added a static array constant, in response to a comment asking about static array initialization. See Array Literals in "The Swift Programming Language".

Notice that both string literals and the string constant can be used to initialize the array. However, since the array type is known the integer constant testStrLength cannot be used in the array initializer.

Use this:

#include <stdlib.h>
#include <string.h>

int main()
{
    const char *d1 = "11";
    int d1int = atoi(d1);
    printf("d1 = %d\n", d1);
    return 0;
}

etc.

declaring the list (and initializing it with an empty arraylist)

List<Card> cardList = new ArrayList<Card>();

adding an element:

Card card;
cardList.add(card);

iterating over elements:

for(Card card : cardList){
    System.out.println(card);
}

I did 2 things to solve this problem.

1. I touched the crontab file, described in this link coderwall.com/p/ry9jwg (Thanks @Andy).
2. Used Emacs instead of my default vim: EDITOR=emacs crontab -e (I have no idea why vim does not work)

crontab -lnow prints the cronjobs. Now I only need to figure out why the cronjobs are still not running ;-)

Here is ready glow hover animation code snippet for this:

http://codepen.io/widhi_allan/pen/ltaCq

-webkit-filter: drop-shadow(0px 0px 0px rgba(255,255,255,0.80));

You're using JSTL 2.0 right? You don't need to put <c:out/> around all variables. Have you tried something like this?

<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
  <c:set var="myVar" value="${myVar}${currentItem}" />
</c:forEach>

Edit: Beaten by the above

In modern browsers you can use Object.getOwnPropertyNames to get all properties (both enumerable and non-enumerable) on an object. For instance:

function Person ( age, name ) {
    this.age = age;
    this.name = name;
}

Person.prototype.greet = function () {
    return "My name is " + this.name;
};

Person.prototype.age = function () {
    this.age = this.age + 1;
};

// ["constructor", "greet", "age"]
Object.getOwnPropertyNames( Person.prototype );

Note that this only retrieves own-properties, so it will not return properties found elsewhere on the prototype chain. That, however, doesn't appear to be your request so I will assume this approach is sufficient.

If you would only like to see enumerable properties, you can instead use Object.keys. This would return the same collection, minus the non-enumerable constructor property.

I had the same problem... I am a complete beginner In my case it happened cause I was trying to do: git merge random_branch/file.txt My problem was solved when I retired the file.txt and let just the branch name (lol) kkfdskfskdfs

git merge random_branch worked pretty well

if mylist != []:

       print(mylist[0])

   else:

       print(None)

You can Use Playlist

Right click on the test method -> Add to playlist -> New playlist

the execution order will be as you add them to the playlist but if you want to change it you have the file

So in simple words: Over clause can be used to select non aggregated values along with Aggregated ones.

Partition BY, ORDER BY inside, and ROWS or RANGE are part of OVER() by clause.

partition by is used to partition data and then perform these window, aggregated functions, and if we don't have partition by the then entire result set is considered as a single partition.

OVER clause can be used with Ranking Functions(Rank, Row_Number, Dense_Rank..), Aggregate Functions like (AVG, Max, Min, SUM...etc) and Analytics Functions like (First_Value, Last_Value, and few others).

Let's See basic syntax of OVER clause

OVER (   
       [ <PARTITION BY clause> ]  
       [ <ORDER BY clause> ]   
       [ <ROW or RANGE clause> ]  
      )  

PARTITION BY: It is used to partition data and perform operations on groups with the same data.

ORDER BY: It is used to define the logical order of data in Partitions. When we don't specify Partition, entire resultset is considered as a single partition

: This can be used to specify what rows are supposed to be considered in a partition when performing the operation.

Let's take an example:

Here is my dataset:

Id          Name                                               Gender     Salary
----------- -------------------------------------------------- ---------- -----------
1           Mark                                               Male       5000
2           John                                               Male       4500
3           Pavan                                              Male       5000
4           Pam                                                Female     5500

6           Aradhya                                            Female     3500
7           Tom                                                Male       5500
8           Mary                                               Female     5000
9           Ben                                                Male       6500
10          Jodi                                               Female     7000
11          Tom                                                Male       5500
12          Ron                                                Male       5000

So let me execute different scenarios and see how data is impacted and I'll come from difficult syntax to simple one

Select *,SUM(salary) Over(order by salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) as sum_sal from employees

7           Tom                                                Male       5500        48500
4           Pam                                                Female     5500        48500
9           Ben                                                Male       6500        55000

Just observe the sum_sal part. Here I am using order by Salary and using "RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW". In this case, we are not using partition so entire data will be treated as one partition and we are ordering on salary. And the important thing here is UNBOUNDED PRECEDING AND CURRENT ROW. This means when we are calculating the sum, from starting row to the current row for each row. But if we see rows with salary 5000 and name="Pavan", ideally it should be 17000 and for salary=5000 and name=Mark, it should be 22000. But as we are using RANGE and in this case, if it finds any similar elements then it considers them as the same logical group and performs an operation on them and assigns value to each item in that group. That is the reason why we have the same value for salary=5000. The engine went up to salary=5000 and Name=Ron and calculated sum and then assigned it to all salary=5000.

So with ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW The difference is for same value items instead of grouping them together, It calculates SUM from starting row to current row and it doesn't treat items with same value differently like RANGE

These results are the same as

Select *, SUM(salary) Over(order by salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) as sum_sal from employees

That is because Over(order by salary) is just a short cut of Over(order by salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) So wherever we simply specify Order by without ROWS or RANGE it is taking RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW as default.

Note: This is applicable only to Functions that actually accept RANGE/ROW. For example, ROW_NUMBER and few others don't accept RANGE/ROW and in that case, this doesn't come into the picture.

Till now we saw that Over clause with an order by is taking Range/ROWS and syntax looks something like this RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW And it is actually calculating up to the current row from the first row. But what If it wants to calculate values for the entire partition of data and have it for each column (that is from 1st row to last row). Here is the query for that

Select *,sum(salary) Over(order by salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) as sum_sal from employees

Instead of CURRENT ROW, I am specifying UNBOUNDED FOLLOWING which instructs the engine to calculate till the last record of partition for each row.

Now coming to your point on what is OVER() with empty braces?

It is just a short cut for Over(order by salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)

Here we are indirectly specifying to treat all my resultset as a single partition and then perform calculations from the first record to the last record of each partition.

It works for me.

The name attribute is used when sending data in a form submission. Different controls respond differently. For example, you may have several radio buttons with different id attributes, but the same name. When submitted, there is just the one value in the response - the radio button you selected.

Of course, there's more to it than that, but it will definitely get you thinking in the right direction.

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

FYI this turned out to be an issue for me where I had two tables in a statement like the following:

SELECT * FROM table1
UNION ALL
SELECT * FROM table2

It worked, but then somewhere along the line the order of columns in one of the table definitions got changed. Changing the * to SELECT column1, column2 fixed the issue. No idea how that happened, but lesson learned!

Slight adjustment to answers from ARobertson and Kenneth Wilson that worked for me.

Running R 3.6.0, with library(tidyverse) and library(dplyr) in my environment:

library(tidyverse)
library(dplyr)
> df %<>% mutate_if(is.character, as.numeric)
Error in df %<>% mutate_if(is.character, as.numeric) : 
  could not find function "%<>%"

I did some quick research and found this note in Hadley's "The tidyverse style guide".

The magrittr package provides the %<>% operator as a shortcut for modifying an object in place. Avoid this operator.

# Good x <- x %>%
           abs() %>%    
           sort()

# Bad x %<>%   
          abs() %>%
          sort()

Solution

Based on that style guide:

df_clean <- df %>% mutate_if(is.character, as.numeric)

Working example

> df_clean <- df %>% mutate_if(is.character, as.numeric)

On Windows, Subversion stores the auth data in %APPDATA%\Subversion\auth. The passwords however are stored encrypted, not in plaintext.

You can decrypt those, but only if you log in to Windows as the same user for which the auth data was saved.

Someone even wrote a tool to decrypt those. Never tried the tool myself so I don't know how well it works, but you might want to try it anyway:

http://www.leapbeyond.com/ric/TSvnPD/

Update: In TortoiseSVN 1.9 and later, you can do it without any additional tools:

Settings Dialog -> Saved Data, then click the "Clear..." button right of the text "Authentication Data". A new dialog pops up, showing all stored authentication data where you can chose which one(s) to clear. Instead of clearing, hold down the Shift and Ctrl button, and then double click on the list. A new column is shown in the dialog which shows the password in clear.

If you prefer to use Guice and you don't want to declare all the bindings, you can also try this adapter:

guice-bridge-jit-injector

Here's a shorter version without the subselect:

SELECT COUNT(DISTINCT DocumentId, DocumentSessionId) FROM DocumentOutputItems

It works fine in MySQL, and I think that the optimizer has an easier time understanding this one.

Edit: Apparently I misread MSSQL and MySQL - sorry about that, but maybe it helps anyway.

This is round robin DNS. This is a quite simple solution for load balancing. Usually DNS servers rotate/shuffle the DNS records for each incoming DNS request. Unfortunately it's not a real solution for fail-over. If one of the servers fail, some visitors will still be directed to this failed server.

You can also use a shorter way:

<?php header('Content-Type: charset=utf-8'); ?>

See RFC 2616. It's valid to specify only character set.

you can try typescript's For :

selectChildren(data , $event){
   let parentChecked : boolean = data.checked;
   for(let o of this.hierarchicalData){
      for(let child of o){
         child.checked = parentChecked;
      }
   }
}

I think to keep controllers for Admin and Front in separate folders, the namespace will work well.

Please look on the below Laravel directory structure, that works fine for me.

app
--Http
----Controllers
------Admin
--------DashboardController.php
------Front
--------HomeController.php

The routes in "routes/web.php" file would be as below

/* All the Front-end controllers routes will work under Front namespace */

Route::group(['namespace' => 'Front'], function () {
    Route::get('/home', 'HomeController@index');
});

And for Admin section, it will look like

/* All the admin routes will go under Admin namespace */
/* All the admin routes will required authentication, 
   so an middleware auth also applied in admin namespace */

Route::group(['namespace' => 'Admin'], function () {
    Route::group(['middleware' => ['auth']], function() {            
        Route::get('/', ['as' => 'home', 'uses' => 'DashboardController@index']);                                   
    });
});

Hope this helps!!

Use display:none/block, instead of visibility, and add a margin-top/bottom for the space you want to see ONLY when the inputs are shown

 function yesnoCheck() {
        if (document.getElementById('yesCheck').checked) {
           document.getElementById('ifYes').style.display = 'block';
        } else {
           document.getElementById('ifYes').style.display = 'none';
        }
    }

and your HTML line for the ifYes tag

<div id="ifYes" style="display:none;margin-top:3%;">If yes, explain:

Well, if you must have it all in one query, you could do a union:

SELECT distributor_id, COUNT() FROM ... UNION
SELECT COUNT() AS EXEC_COUNT FROM ... WHERE level = 'exec' UNION
SELECT COUNT(*) AS PERSONAL_COUNT FROM ... WHERE level = 'personal';

Or, if you can do after processing:

SELECT distributor_id, COUNT(*) FROM ... GROUP BY level;

You will get the count for each level and need to sum them all up to get the total.

This works for me

$('.someclass').click(function() {
    $varName = $(this).data('fulltext');
    console.log($varName);
});

Why not just:

names, counts = zip(*D.items())
plt.bar(names, counts)

The python cProfile and pstats modules offer great support for measuring time elapsed in certain functions without having to add any code around the existing functions.

For example if you have a python script timeFunctions.py:

import time

def hello():
    print "Hello :)"
    time.sleep(0.1)

def thankyou():
    print "Thank you!"
    time.sleep(0.05)

for idx in range(10):
    hello()

for idx in range(100):
    thankyou()

To run the profiler and generate stats for the file you can just run:

python -m cProfile -o timeStats.profile timeFunctions.py

What this is doing is using the cProfile module to profile all functions in timeFunctions.py and collecting the stats in the timeStats.profile file. Note that we did not have to add any code to existing module (timeFunctions.py) and this can be done with any module.

Once you have the stats file you can run the pstats module as follows:

python -m pstats timeStats.profile

This runs the interactive statistics browser which gives you a lot of nice functionality. For your particular use case you can just check the stats for your function. In our example checking stats for both functions shows us the following:

Welcome to the profile statistics browser.
timeStats.profile% stats hello
<timestamp>    timeStats.profile

         224 function calls in 6.014 seconds

   Random listing order was used
   List reduced from 6 to 1 due to restriction <'hello'>

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
       10    0.000    0.000    1.001    0.100 timeFunctions.py:3(hello)

timeStats.profile% stats thankyou
<timestamp>    timeStats.profile

         224 function calls in 6.014 seconds

   Random listing order was used
   List reduced from 6 to 1 due to restriction <'thankyou'>

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
      100    0.002    0.000    5.012    0.050 timeFunctions.py:7(thankyou)

The dummy example does not do much but give you an idea of what can be done. The best part about this approach is that I dont have to edit any of my existing code to get these numbers and obviously help with profiling.

You can get all keys / values and preserve the hierarchy with this

// get keys of an object or array
function getkeys(z){
  var out=[]; 
  for(var i in z){out.push(i)};
  return out;
}

// print all inside an object
function allInternalObjs(data, name) {
  name = name || 'data';
  return getkeys(data).reduce(function(olist, k){
    var v = data[k];
    if(typeof v === 'object') { olist.push.apply(olist, allInternalObjs(v, name + '.' + k)); }
    else { olist.push(name + '.' + k + ' = ' + v); }
    return olist;
  }, []);
}

// run with this
allInternalObjs({'a':[{'b':'c'},{'d':{'e':5}}],'f':{'g':'h'}}, 'ob')

This is a modification on (https://stackoverflow.com/a/25063574/1484447)

try this. There are in general three ways to use mysqldump—

in order to dump a set of one or more tables,

shell> mysqldump [options] db_name [tbl_name ...]

a set of one or more complete databases

shell> mysqldump [options] --databases db_name ...

or an entire MySQL server—as shown here:

shell> mysqldump [options] --all-databases

Just supply -s to your read call like so:

$ read -s PASSWORD
$ echo $PASSWORD

public string Type { get; set; } 

is no different than doing

private string _Type;

public string Type
{    
  get { return _Type; }
  set { _Type = value; }
}

Have you tried just "TYPE1"? I suppose Spring uses reflection to determine the type of "type" anyway, so the fully qualified name is redundant. Spring generally doesn't subscribe to redundancy!

Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.

Here is an example :

function delsheets(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
  for (pa=numbofsheet-1;pa>0;--pa){ 
    ss.setActiveSheet(ss.getSheets()[pa]);
    var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
    Utilities.sleep(200);// pause in the loop for 200 milliseconds
  }
  ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}

You can use following command and change AJAY SUNDRIYAL with your system name.This is only for your debug.keystore.This will work for you.

C:\Program Files\Java\jdk1.8.0_91\bin>keytool -list -v -keystore "c:\users\AJAY SUNDRIYAL\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

Here is another solution (only relevant declarations listed):

.text span {
   display:inline-block;
   margin-right:100%;
}

When the margin is expressed in percentage, that percentage is taken from the width of the parent node, so 100% means as wide as the parent, which results in the next element getting "pushed" to a new line.

I think

from io import open

should do.

Here's a basic jQuery plugin I wrote that selects all checkboxes on the page, except the checkbox/element that is to be used as the toggle:

(function($) {
    // Checkbox toggle function for selecting all checkboxes on the page
    $.fn.toggleCheckboxes = function() {
        // Get all checkbox elements
        checkboxes = $(':checkbox').not(this);

        // Check if the checkboxes are checked/unchecked and if so uncheck/check them
        if(this.is(':checked')) {
            checkboxes.prop('checked', true);
        } else {
            checkboxes.prop('checked', false);
        }
    }
}(jQuery));

Then simply call the function on your checkbox or button element:

// Check all checkboxes
$('.check-all').change(function() {
    $(this).toggleCheckboxes();
});

Open Oracle SQLDeveloper

Right click on connection tab and select new connection

Enter HR_ORCL in connection name and HR for the username and password.

Specify localhost for your Hostname and enter ORCL for the SID.

Click Test.

The status of the connection Test Successfully.

The connection was not saved however click on Save button to save the connection. And then click on Connect button to connect your database.

The connection is saved and you see the connection list.

This parameter is is working for me:

--enable-easy-off-store-extension-install

Do the following:

1. Right click on your "Chrome" icon.
2. Choose properties
3. At the end of your target line, place these parameters: --enable-easy-off-store-extension-install
4. It should look like: chrome.exe --enable-easy-off-store-extension-install
5. Start Chrome by double-clicking on the icon

Here is the class for thread safe list without lock

 public class ConcurrentList   
    {
        private long _i = 1;
        private ConcurrentDictionary<long, T> dict = new ConcurrentDictionary<long, T>();  
        public int Count()
        {
            return dict.Count;
        }
         public List<T> ToList()
         {
            return dict.Values.ToList();

            return dict.Values.Where(p).FirstOrDefault();
        }
        public bool Any(Func<T, bool> p)
        {
            return dict.Values.Where(p).Count() > 0 ? true : false;
        }
        public void Clear()
        {
            dict.Clear();
        }
        private void CheckReset()
        {

        }
        private void Reset()
        {
            _i = 1;
        }
    }

In Swift 5:

    var i = 9897

    func timeString(time: TimeInterval) -> String {
        let hour = Int(time) / 3600
        let minute = Int(time) / 60 % 60
        let second = Int(time) % 60

        // return formated string
        return String(format: "%02i:%02i:%02i", hour, minute, second)
    }

To call function

    timeString(time: TimeInterval(i))

Will return 02:44:57

You will have to make a call to the YouTube data API's video resource after you make the search call. You can put up to 50 video IDs in a search, so you won't have to call it for each element.

https://developers.google.com/youtube/v3/docs/videos/list

You'll want to set part=contentDetails, because the duration is there.

For example, the following call:

https://www.googleapis.com/youtube/v3/videos?id=9bZkp7q19f0&part=contentDetails&key={YOUR_API_KEY}

Gives this result:

{
 "kind": "youtube#videoListResponse",
 "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/ny1S4th-ku477VARrY_U4tIqcTw\"",
 "items": [
  {

   "id": "9bZkp7q19f0",
   "kind": "youtube#video",
   "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/HN8ILnw-DBXyCcTsc7JG0z51BGg\"",
   "contentDetails": {
    "duration": "PT4M13S",
    "dimension": "2d",
    "definition": "hd",
    "caption": "false",
    "licensedContent": true,
    "regionRestriction": {
     "blocked": [
      "DE"
     ]
    }
   }
  }
 ]
}

The time is formatted as an ISO 8601 string. PT stands for Time Duration, 4M is 4 minutes, and 13S is 13 seconds.

You're going to have a hard time writing to the same file you're reading from. One quick way is to simply do this:

File.WriteAllText("test.txt", File.ReadAllText("test.txt").Replace("some text","some other text"));

You can lay that out better with

string str = File.ReadAllText("test.txt");
str = str.Replace("some text","some other text");
File.WriteAllText("test.txt", str);

You probably want to use something like jQuery, which makes JS programming easier.

Something like:

$(document).ready(function(){
   // Your code here
});

Would seem to do what you are after.

Use the -S (note: capital S) switch to GCC, and it will emit the assembly code to a file with a .s extension. For example, the following command:

gcc -O2 -S -c foo.c

Pretty sure you could've made that into a three line example. :)

If you want exact precision, use BigDecimal. Otherwise, you can use ints multiplied by 10 ^ whatever precision you want.

Try this extension method out. Hopefully this could help.

public static class DistinctHelper
{
    public static IEnumerable<TSource> DistinctBy<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector)
    {
        var identifiedKeys = new HashSet<TKey>();
        return source.Where(element => identifiedKeys.Add(keySelector(element)));
    }
}

Usage:

var outputList = sourceList.DistinctBy(x => x.TargetProperty);

you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM

1 10 * * * php -f /var/www/package/index.php controller function

30 14 * * * php -f /var/www/package/index.php controller function

but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .

30 10,14 * * * php -f /var/www/package/index.php controller function

The name property is marked as protected. This was added in TypeScript 1.3 and is now firmly established.

The makeSound method is marked as abstract, as is the class. You cannot directly instantiate an Animal now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.

abstract class Animal {
    constructor(protected name: string) { }

    abstract makeSound(input : string) : string;

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name: string) { super(name); }

    makeSound(input : string) : string {
        return "sssss"+input;
    }

    move() {
        alert("Slithering...");
        super.move(5);
    }
}

The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:

class Animal {
    constructor(public name) { }
    makeSound(input : string) : string {
        throw new Error('This method is abstract');
    }
    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    constructor(name) { super(name); }
    makeSound(input : string) : string {
        return "sssss"+input;
    }
    move() {
        alert("Slithering...");
        super.move(5);
    }
}

This is kind of overriding the thing of one page, but... You could use iframes in HTML.

<html>
<body>
<iframe src="page1.html" border="0"></iframe>
</body>
</html>

And page1.html would be your base page. Your still making multiple pages, but your browser just doesn't move. So lets say thats your index.html. You have tabs, you click page 2, your url wont change, but the page will. All in iframes. The only thing different, is that you can view the frame source as well.

For this problem the best solution I use is to have a CLR function in Sql Server 2005 that uses one of DateTime.Parse or ParseExact function to return the DateTime value with a specified format.

The main thing is that if you don't store in onSaveInstanceState() then onRestoreInstanceState() will not be called. This is the main difference between restoreInstanceState() and onCreate(). Make sure you really store something. Most likely this is your problem.

After inspecting the sample website you provided, I found that the author might achieve the effect by using a library called Stellar.js, take a look at the library site, cheers!

First of all i say that you should google this as it is defined in detail in many places

Local
These variables only exist inside the specific function that creates them. They are unknown to other functions and to the main program. As such, they are normally implemented using a stack. Local variables cease to exist once the function that created them is completed. They are recreated each time a function is executed or called.

Global
These variables can be accessed (ie known) by any function comprising the program. They are implemented by associating memory locations with variable names. They do not get recreated if the function is recalled.

/* Demonstrating Global variables  */
    #include <stdio.h>
    int add_numbers( void );                /* ANSI function prototype */

    /* These are global variables and can be accessed by functions from this point on */
    int  value1, value2, value3;

    int add_numbers( void )
    {
        auto int result;
        result = value1 + value2 + value3;
        return result;
    }

    main()
    {
        auto int result;
        value1 = 10;
        value2 = 20;
        value3 = 30;        
        result = add_numbers();
        printf("The sum of %d + %d + %d is %d\n",
            value1, value2, value3, final_result);
    }


    Sample Program Output
    The sum of 10 + 20 + 30 is 60

The scope of global variables can be restricted by carefully placing the declaration. They are visible from the declaration until the end of the current source file.

#include <stdio.h>
void no_access( void ); /* ANSI function prototype */
void all_access( void );

static int n2;      /* n2 is known from this point onwards */

void no_access( void )
{
    n1 = 10;        /* illegal, n1 not yet known */
    n2 = 5;         /* valid */
}

static int n1;      /* n1 is known from this point onwards */

void all_access( void )
{
    n1 = 10;        /* valid */
    n2 = 3;         /* valid */
}

Static:
Static object is an object that persists from the time it's constructed until the end of the program. So, stack and heap objects are excluded. But global objects, objects at namespace scope, objects declared static inside classes/functions, and objects declared at file scope are included in static objects. Static objects are destroyed when the program stops running.
I suggest you to see this tutorial list

AUTO:
C, C++

(Called automatic variables.)

All variables declared within a block of code are automatic by default, but this can be made explicit with the auto keyword.[note 1] An uninitialized automatic variable has an undefined value until it is assigned a valid value of its type.[1]

Using the storage class register instead of auto is a hint to the compiler to cache the variable in a processor register. Other than not allowing the referencing operator (&) to be used on the variable or any of its subcomponents, the compiler is free to ignore the hint.

In C++, the constructor of automatic variables is called when the execution reaches the place of declaration. The destructor is called when it reaches the end of the given program block (program blocks are surrounded by curly brackets). This feature is often used to manage resource allocation and deallocation, like opening and then automatically closing files or freeing up memory.SEE WIKIPEDIA

If you are running puppet it may set /proc/sys/kernel/modules_disabled to 1, inhibiting further module loading. When the machine is reboot, it gets set back to 0, allowing for changes, such as loading the iptables modules. After a certain amount of time puppet will set it back to 1 to protect the system from kernel root kits. Therefore, whatever modules that we are going to need should be loaded during or shortly after boot time.

Just download and install LocalDB 64BIT\SqlLocalDB.msi can also solve this problem. You don't really need to uninstall and reinstall SQL Server 2014 Express with Advanced Services.

@drop-shadow if you're using Hibernate, you can call Hibernate.initialize() when you invoke the getStudents() method:

Public class UniversityDaoImpl extends GenericDaoHibernate<University, Integer> implements UniversityDao {
    //...
    @Override
    public University get(final Integer id) {
        Query query = getQuery("from University u where idUniversity=:id").setParameter("id", id).setMaxResults(1).setFetchSize(1);
        University university = (University) query.uniqueResult();
        ***Hibernate.initialize(university.getStudents());***
        return university;
    }
    //...
}

Use the preprocessor # operator:

#define CALL_DO_SOMETHING(VAR) do_something(#VAR, VAR);

You can use WhereNotIn in following way also:

ModelName::whereNotIn('book_price', [100,200])->get(['field_name1','field_name2']);

This will return collection of Record with specific fields

Personally, I'd use file_put_contents and file_get_contents (these are wrappers for fopen, fputs, etc).

Also, if you are going to write any structured data, such as arrays, I suggest you serialize and unserialize the files contents.

$file = '/tmp/file';
$content = serialize($my_variable);
file_put_contents($file, $content);
$content = unserialize(file_get_contents($file));

Yes, there's str_to_date

mysql> select str_to_date("03/02/2009","%d/%m/%Y");
+--------------------------------------+
| str_to_date("03/02/2009","%d/%m/%Y") |
+--------------------------------------+
| 2009-02-03                           |
+--------------------------------------+
1 row in set (0.00 sec)

Old question, but I see that this thread was fairly recently active, so I'll go ahead and throw in my two cents:

Pretty much exactly what Mitch said. Assuming proper indexing, you can just go ahead and use square bracket notation as if you were accessing an array. In addition to using the numeric index, though, if your members have specific names, you can often do kind of a simultaneous search/access by typing something like:

var temp = list1["DesiredMember"];

The more you know, right?

Visual Studio 2015 doesn't install C++ by default. You have to rerun the setup, select Modify and then check Programming Language -> C++

You didn't select post_id in the subquery. You have to select it in the subquery like this:

SELECT wp_woocommerce_order_items.order_id As No_Commande
FROM  wp_woocommerce_order_items
LEFT JOIN 
    (
        SELECT meta_value As Prenom, post_id  -- <----- this
        FROM wp_postmeta
        WHERE meta_key = '_shipping_first_name'
    ) AS a
ON wp_woocommerce_order_items.order_id = a.post_id
WHERE  wp_woocommerce_order_items.order_id =2198 

Oops... Misunderstood the question...

Pause is the way to go

Old answer:

you can pipe commands into your patch file...

try

build.bat < responsefile.txt

you can try this and don't need JQuery: timeSolver.js

For example, add 5 day on today:

var newDay = timeSolver.add(new Date(),5,"day");

You also can add by hour, month...etc. please see for more infomation.

If you want use RegEx in .NET,

Regex rx = new Regex(@"^([\w]+)(\-)*");
var match = rx.Match("thisis-thefirst");
var text = match.Groups[1].Value;
Assert.AreEqual("thisis", text);

Forcefully Change History

Assuming you don't just want to delete the last commit, but you want to delete specific commits of the last n commits, go with:

git rebase -i HEAD~<number of commits to go back>, so git rebase -i HEAD~5 if you want to see the last five commits.

Then in the text editor change the word pick to drop next to every commit you would like to remove. Save and quit the editor. Voila!

Additively Change History

Try git revert <commit hash>. Revert will create a new commit that undoes the specified commit.

First change apache listen port 80 to 8080 apache in /etc/apache2/ports.conf include

Listen 1.2.3.4:80 to 1.2.3.4:8080
sudo service apache2 restart 

or

sudo service httpd restart    // in case of centos

then add nginx as reverse proxy server that will listen apache port

server {
 listen   1.2.3.4:80;
 server_name  some.com;

 access_log  /var/log/nginx/something-access.log;

 location / {
  proxy_pass http://localhost:8080;
  proxy_redirect off;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 }


location ~* ^.+\.(jpg|js|jpeg|png)$ {
   root /usr/share/nginx/html/;
}

location /404.html {
  root /usr/share/nginx/html/40x.html;
}

error_page 404 /404.html;
    location = /40x.html {
}

error_page 500 502 503 504 /50x.html;
    location = /50x.html {
}

# put code for static content like js/css/images/fonts
}

After changes restart nginx server

sudo service nginx restart

Now all traffic will be handled by nginx server and send all dynamic request to apache and static conten is served by nginx server.

For advance configuration like cache :

https://www.linode.com/docs/web-servers/nginx/slightly-more-advanced-configurations-for-nginx/#basic-nginx-caching

Some times eclipse may confuse with other projects in the same directory.

Just change package name (don't forget to change in Android manifest file also), ensure the package name is not used already in the directory. It may work.

$("#locationthemes").prop("checked")

In Python 3, TemporaryDirectory in the tempfile module can be used.

This is straight from the examples:

import tempfile
with tempfile.TemporaryDirectory() as tmpdirname:
     print('created temporary directory', tmpdirname)
# directory and contents have been removed

If you would like to keep the directory a bit longer, you could do something like this:

import tempfile

temp_dir = tempfile.TemporaryDirectory()
print(temp_dir.name)
# use temp_dir, and when done:
temp_dir.cleanup()

The documentation also says that "On completion of the context or destruction of the temporary directory object the newly created temporary directory and all its contents are removed from the filesystem." So at the end of the program, for example, Python will clean up the directory if it wasn't explicitly removed. Python's unittest may complain of ResourceWarning: Implicitly cleaning up <TemporaryDirectory... if you rely on this, though.

Try Base64 encoding/decoding your binary data. Also look into CDATA sections

The reason for this error occurs is that you are using the CryptoListPresenter _presenter without initializing.

I found that CryptoListPresenter _presenter would have to be initialized to fix because _presenter.loadCurrencies() is passing through a null variable at the time of instantiation;

there are two ways to initialize

1. Can be initialized during an declaration, like this

   CryptoListPresenter _presenter = CryptoListPresenter();
   

2. In the second, initializing(with assigning some value) it when initState is called, which the framework will call this method once for each state object.

   @override
   void initState() {
     _presenter = CryptoListPresenter(...);
   }
   

Following code might be useful if someone is using React and has a different component of Marker and want to remove marker from map.

export default function useGoogleMapMarker(props) {
  const [marker, setMarker] = useState();

  useEffect(() => {
    // ...code
    const marker = new maps.Marker({ position, map, title, icon });
    // ...code
    setMarker(marker);
    return () => marker.setMap(null); // to remove markers when unmounts
  }, []);

  return marker;
}

The shortest way (will print "not same" because String comparison is case sensitive):

def compareString = {
   it == "india" ? "same" : "not same"
}    

compareString("India")

var map_marker = $(".map-marker").children("img").attr("src") var pinImage = new google.maps.MarkerImage(map_marker);

     var marker = new google.maps.Marker({
      position: uluru,
      map: map,
      icon: pinImage
    });
  }

I was facing the same issue but I switched 26.0.0-beta1 dependencies to 26.1.0 and it's working now.

Just a note in case others have the same problem.

I had the same problem and found a different answer. I found that getting the height of a div that's height is determined by its contents needs to be initiated on window.load, or window.scroll not document.ready otherwise i get odd heights/smaller heights, i.e before the images have loaded. I also used outerHeight().

var currentHeight = 0;
$(window).load(function() {
    //get the natural page height -set it in variable above.

    currentHeight = $('#js_content_container').outerHeight();

    console.log("set current height on load = " + currentHeight)
    console.log("content height function (should be 374)  = " + contentHeight());   

});

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

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

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

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

@Robino was suggesting to add some tests which make sense, so here is a simple benchmark between 3 possible ways (maybe the most used ones) to convert an iterator to a list:

1. by type constructor

list(my_iterator)

1. by unpacking

[*my_iterator]

3. using list comprehension

[e for e in my_iterator]

I have been using simple_bechmark library

from simple_benchmark import BenchmarkBuilder
from heapq import nsmallest

b = BenchmarkBuilder()

@b.add_function()
def convert_by_type_constructor(size):
    list(iter(range(size)))

@b.add_function()
def convert_by_list_comprehension(size):
    [e for e in iter(range(size))]

As you can see there is very hard to make a difference between conversion by the constructor and conversion by unpacking, conversion by list comprehension is the “slowest” approach.

I have been testing also across different Python versions (3.6, 3.7, 3.8, 3.9) by using the following simple script:

import argparse
import timeit

parser = argparse.ArgumentParser(
    description='Test convert iterator to list')
parser.add_argument(
    '--size', help='The number of elements from iterator')

args = parser.parse_args()

size = int(args.size)
repeat_number = 10000

# do not wait too much if the size is too big
if size > 10000:
    repeat_number = 100


def test_convert_by_type_constructor():
    list(iter(range(size)))


def test_convert_by_list_comprehension():
    [e for e in iter(range(size))]


def test_convert_by_unpacking():
    [*iter(range(size))]


def get_avg_time_in_ms(func):
    avg_time = timeit.timeit(func, number=repeat_number) * 1000 / repeat_number
    return round(avg_time, 6)


funcs = [test_convert_by_type_constructor,
         test_convert_by_unpacking, test_convert_by_list_comprehension]

print(*map(get_avg_time_in_ms, funcs))

The script will be executed via a subprocess from a Jupyter Notebook (or a script), the size parameter will be passed through command-line arguments and the script results will be taken from standard output.

from subprocess import PIPE, run

import pandas

simple_data = {'constructor': [], 'unpacking': [], 'comprehension': [],
        'size': [], 'python version': []}


size_test = 100, 1000, 10_000, 100_000, 1_000_000
for version in ['3.6', '3.7', '3.8', '3.9']:
    print('test for python', version)
    for size in size_test:
        command = [f'python{version}', 'perf_test_convert_iterator.py', f'--size={size}']
        result = run(command, stdout=PIPE, stderr=PIPE, universal_newlines=True)
        constructor, unpacking,  comprehension = result.stdout.split()
        
        simple_data['constructor'].append(float(constructor))
        simple_data['unpacking'].append(float(unpacking))
        simple_data['comprehension'].append(float(comprehension))
        simple_data['python version'].append(version)
        simple_data['size'].append(size)

df_ = pandas.DataFrame(simple_data)
df_

You can get my full notebook from here.

In most of the cases, in my tests, unpacking shows to be faster, but the difference is so small that the results may change from a run to the other. Again, the comprehension approach is the slowest, in fact, the other 2 methods are up to ~ 60% faster.

It was already pointed in this comment and in this answer, but I'll try to give a more direct answer to the question:

from IPython.display import display
import numpy as np
import pandas as pd

n = 100
foo = pd.DataFrame(index=range(n))
foo['floats'] = np.random.randn(n)

with pd.option_context("display.max_rows", foo.shape[0]):
    display(foo)

pandas.option_context is available since pandas 0.13.1 (pandas 0.13.1 release notes). According to this,

[it] allow[s] you to execute a codeblock with a set of options that revert to prior settings when you exit the with block.

Where you have written the code

public class Main {
    public static void main(String args[])
    {
        Calculate obj = new Calculate(1,2,'+');
        obj.getAnswer();
    }
}

Here you have to run the class "Main" instead of the class you created at the start of the program. To do so pls go to Run Configuration and search for this class name"Main" which is having the main method inside this(public static void main(String args[])). And you will get your output.

I met the same situation under windows, and searched for the solution.

Seeing this post Install mysql-python (Windows).

It points out installing such a pip environment is difficult, needs many other dependencies.

But I finally know that if we use mysqlclient with a version down to 1.3.4, it don't need that requirements any more, so try:

pip install mysqlclient==1.3.4

In iOS 9.1 and lower, go to Settings - General - Profiles - tap on your Profile - tap on Trust button.

In iOS 9.2+ & iOS 11+ go to: Settings - General - Profiles & Device Management - tap on your Profile - tap on Trust button.

In iOS 10+, go to: Settings - General - Device Management - tap on your Profile - tap on Trust button.

For your idea, actually you are approaching the success, but if you do like this should be fine:

for (int i=0;i<String_Array.length;i++) String_Array[i]=(String)Object_Array[i];

BTW, using the Arrays utility method is quite good and make the code elegant.

Kevlar is correct.

An alternative to a custom DLL is Lua Alien

That's because endOf mutates the original value.

Relevant quote:

Mutates the original moment by setting it to the end of a unit of time.

Here's an example function that gives you the output you want:

function getMonthDateRange(year, month) {
    var moment = require('moment');

    // month in moment is 0 based, so 9 is actually october, subtract 1 to compensate
    // array is 'year', 'month', 'day', etc
    var startDate = moment([year, month - 1]);

    // Clone the value before .endOf()
    var endDate = moment(startDate).endOf('month');

    // just for demonstration:
    console.log(startDate.toDate());
    console.log(endDate.toDate());

    // make sure to call toDate() for plain JavaScript date type
    return { start: startDate, end: endDate };
}

References:

• endOf()
• clone()
• Date from object

If you have <repositories/> defined in your pom.xml apparently your local repository is ignored.

This code sample can be used to change date format. Here I want to change from yyyy-MM-dd to dd-MM-yyyy. Here pos is position of column.

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    Date d=null;
    try {
        d= sdf.parse(cell.getStringCellValue());
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        d=null;
        e.printStackTrace();
        continue;
    }
    cell.setCellValue(d);
    cell.setCellStyle(cellStyle);
   }

file.close();
FileOutputStream outFile =new FileOutputStream(new File(output));

#define Enum(Name, ...) TypedEnum(Name, __VA_ARGS__)

To declare an enum:

Enum(TestEnum, 
Enum_1= 0,
Enum_2= 1,
Enum_3= 2,
Enum_4= 4,
Enum_5= 8,
Enum_6= 16,
Enum_7= 32);

the max will be available here:

int array [TestEnum::TestEnum_MAX];
for(uint32_t fIdx = 0; fIdx < TestEnum::TestEnum_MAX; fIdx++)
{
     array [fIdx] = 0;
}

Use "target" attribute and remove the 'compiler' attribute. See here. So it should go something like this:

<target name="compile">
  <javac target="1.5" srcdir=.../>
</target>

Hope this helps

Here is one quick suggestion for creating variable names. If you want the variable not to conflict when being used in FireFox, do not use the variable name "_content" as this variable name is already being used by the browser. I found this out the hard way and had to change all of the places I used the variable "_content" in a large JavaScript application.

This is an example without using the onClick event. I simply pass a callback function to the child by props. With that callback the child call also send data back. I was inspired by the examples in the docs.

Small example (this is in a tsx files, so props and states must be declared fully, I deleted some logic out of the components, so it is less code).

*Update: Important is to bind this to the callback, otherwise the callback has the scope of the child and not the parent. Only problem: it is the "old" parent...

SymptomChoser is the parent:

interface SymptomChooserState {
  // true when a symptom was pressed can now add more detail
  isInDetailMode: boolean
  // since when user has this symptoms
  sinceDate: Date,
}

class SymptomChooser extends Component<{}, SymptomChooserState> {

  state = {
    isInDetailMode: false,
    sinceDate: new Date()
  }

  helloParent(symptom: Symptom) {
    console.log("This is parent of: ", symptom.props.name);
    // TODO enable detail mode
  }

  render() {
    return (
      <View>
        <Symptom name='Fieber' callback={this.helloParent.bind(this)} />
      </View>
    );
  }
}

Symptom is the child (in the props of the child I declared the callback function, in the function selectedSymptom the callback is called):

interface SymptomProps {
  // name of the symptom
  name: string,
  // callback to notify SymptomChooser about selected Symptom.
  callback: (symptom: Symptom) => void
}

class Symptom extends Component<SymptomProps, SymptomState>{

  state = {
    isSelected: false,
    severity: 0
  }

  selectedSymptom() {
    this.setState({ isSelected: true });
    this.props.callback(this);
  }

  render() {
    return (
      // symptom is not selected
      <Button
        style={[AppStyle.button]}
        onPress={this.selectedSymptom.bind(this)}>
        <Text style={[AppStyle.textButton]}>{this.props.name}</Text>
      </Button>
    );
  }
}

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

You can use the memcpy(),

void * memcpy ( void * destination, const void * source, size_t num );

memcpy() copies the values of num bytes from the location pointed by source directly to the memory block pointed by destination.

If the destination and source overlap, then you can use memmove().

void * memmove ( void * destination, const void * source, size_t num );

memmove() copies the values of num bytes from the location pointed by source to the memory block pointed by destination. Copying takes place as if an intermediate buffer were used, allowing the destination and source to overlap.

To flatten a MultiIndex inside a chain of other DataFrame methods, define a function like this:

def flatten_index(df):
  df_copy = df.copy()
  df_copy.columns = ['_'.join(col).rstrip('_') for col in df_copy.columns.values]
  return df_copy.reset_index()

Then use the pipe method to apply this function in the chain of DataFrame methods, after groupby and agg but before any other methods in the chain:

my_df \
  .groupby('group') \
  .agg({'value': ['count']}) \
  .pipe(flatten_index) \
  .sort_values('value_count')

After some research on this topic, I found that the error is occured basically if you have an instance of db created previously on your local sql server express. So whenever you have updates on db and try to update the db/run some code on db without running Update Database command using Package Manager Console; first of all, you have to delete previous db on our local sql express manually.

Also, this solution works unless you have AutomaticMigrationsEnabled = false;in your Configuration.

If you work with a version control system (git,svn,etc.) and some other developers update db objects in production phase then this error rises whenever you update your code base and run the application.

As stated above, there are some solutions for this on code base. However, this is the most practical one for some cases.

Try this: ioreg -p IOUSB -l -b | grep -E "@|PortNum|USB Serial Number"

pathMatch = 'full' results in a route hit when the remaining, unmatched segments of the URL match is the prefix path

pathMatch = 'prefix' tells the router to match the redirect route when the remaining URL begins with the redirect route's prefix path.

Ref: https://angular.io/guide/router#set-up-redirects

pathMatch: 'full' means, that the whole URL path needs to match and is consumed by the route matching algorithm.

pathMatch: 'prefix' means, the first route where the path matches the start of the URL is chosen, but then the route matching algorithm is continuing searching for matching child routes where the rest of the URL matches.

Using session, I successfully passed a parameter (name) from servlet #1 to servlet #2, using response.sendRedirect in servlet #1. Servlet #1 code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) {
    String name = request.getParameter("name");
    String password = request.getParameter("password");
    ...
    request.getSession().setAttribute("name", name);
    response.sendRedirect("/todo.do");

In Servlet #2, you don't need to get name back. It's already connected to the session. You could do String name = (String) request.getSession().getAttribute("name"); ---but you don't need this.

If Servlet #2 calls a JSP, you can show name this way on the JSP webpage:

<h1>Welcome ${name}</h1>

We are using Elasticsearch version 1.6 and I used this query from a co-worker to cover not null and not empty for a field:

              }
            },
            {

                }
              }
            }
          ]
        }
      }
    }
  }
}

You can use in swift 4 or 5

    let date = Date()
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss"
    let current_date_time = dateFormatter.string(from: date)
    print("before add time-->",current_date_time)

    //adding 5 miniuts
    let addminutes = date.addingTimeInterval(5*60)
    dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss"
    let after_add_time = dateFormatter.string(from: addminutes)
    print("after add time-->",after_add_time)

output:

before add time--> 2020-02-18 10:38:15
after add time--> 2020-02-18 10:43:15

Podfile.lock file right under Podfile within your project.

The main thing is , Force it to open through your favourite TextEditor, like Sublime or TextEdit [Open With -> Select Sublime] as it doesn't give an option straight away to open.

The FLAG_ACTIVITY_NO_ANIMATION flag works fine for disabling the animation when starting activities.

To disable the similar animation that is triggered when calling finish() on an Activity, i.e the animation slides from right to left instead, you can call overridePendingTransition(0, 0) after calling finish() and the next animation will be excluded.

This also works on the in-animation if you call overridePendingTransition(0, 0) after calling startActivity(...).

This works for me in Ubuntu 12.04 and 15.10

if pip not installed:

sudo apt-get install python-pip

and then:

sudo apt-get update
sudo apt-get install libpq-dev python-dev
sudo pip install psycopg2

This line looks suspicious:

invaders[i] = inv;

You're never incrementing i, so you keep assigning to invaders[0]. If this is just an error you made when reducing your code to the example, check how you calculate i in the real code; you could be exceeding the size of invaders.

If as your comment suggests, you're creating 55 invaders, then check that invaders has been initialised correctly to handle this number.

From http://docs.python.org/library/csv.html#csv.writer:

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

In other words, when opening the file you pass 'wb' as opposed to 'w'.
You can also use a with statement to close the file when you're done writing to it.
Tested example below:

from __future__ import with_statement # not necessary in newer versions
import csv
headers=['id', 'year', 'activity', 'lineitem', 'datum']
with open('file3.csv','wb') as fou: # note: 'wb' instead of 'w'
    output = csv.DictWriter(fou,delimiter=',',fieldnames=headers)
    output.writerow(dict((fn,fn) for fn in headers))
    output.writerows(rows)

Those who installed node.js via the package manager can just run:

sudo apt-get purge nodejs

Optionally if you have installed it by adding the official NodeSource repository as stated in Installing Node.js via package manager, do:

sudo rm /etc/apt/sources.list.d/nodesource.list

If you want to clean up npm cache as well:

rm -rf ~/.npm

It is bad practice to try to remove things manually, as it can mess up the package manager, and the operating system itself. This answer is completely safe to follow

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

It's very nice to see so many spirited approaches to this problem. Quite inspiring indeed!

I came across this topic searching for a simple iterative solution for deleting all nodes in my binary tree implementation. I tried some of them, and I tried something similar found elsewhere on the Net, but none of them were really to my liking.

The thing is, I am developing a database indexing module for a very specific purpose (Bitcoin Blockchain indexing), and my data is stored on disk, not in RAM. I swap in pages as needed, doing my own memory management. It's slower, but fast enough for the purpose, and with having storage on disk instead of RAM, I have no religious bearings against wasting space (hard disks are cheap).

For that reason my nodes in my binary tree have parent pointers. That's (all) the extra space I'm talking about. I need the parents because I need to iterate both ascending and descending through the tree for various purposes.

Having that in my mind, I quickly wrote down a little piece of pseudo-code on how it could be done, that is, a post-order traversal deleting nodes on the fly. It's implemented and tested, and became a part of my solution. And it's pretty fast too.

The thing is: It gets really, REALLY, simple when nodes have parent pointers, and furthermore since I can null out the parent's link to the "just departed" node.

Here's the pseudo-code for iterative post-order deletion:

Node current = root;
while (current)
{
  if (current.left)       current = current.left;  // Dive down left
  else if (current.right) current = current.right; // Dive down right
  else
  {
    // Node "current" is a leaf, i.e. no left or right child
    Node parent = current.parent; // assuming root.parent == null
    if (parent)
    {
      // Null out the parent's link to the just departing node
      if (parent.left == current) parent.left = null;

If you are interested in a more theoretical approach to coding complex collections (such as my binary tree, which is really a self-balancing red-black-tree), then check out these links:

Happy coding :-)

Although the other answers posted here work, I find the following approach more natural:

$obj = (object) [
    'aString' => 'some string',
    'anArray' => [ 1, 2, 3 ]
];

echo json_encode($obj);

C++11 brought us lambdas, which can be incredibly useful in this situation:

#define MACRO(X,Y)                              \
    [&](x_, y_) {                               \
        cout << "1st arg is:" << x_ << endl;    \
        cout << "2nd arg is:" << y_ << endl;    \
        cout << "Sum is:" << (x_ + y_) << endl; \
    }((X), (Y))

You keep the generative power of macros, but have a comfy scope from which you can return whatever you want (including void). Additionally, the issue of evaluating macro parameters multiple times is avoided.

I have looked around for a fix for this. I have a jquery mobile site that has a final print page and it combines dozens of pages. I tried all the fixes above but the only thing I could get to work is this:

<div style="clear:both!important;"/></div>
<div style="page-break-after:always"></div> 
<div style="clear:both!important;"/> </div>

I used following code on my sample application to start new activity.

Button next = (Button) findViewById(R.id.TEST);
next.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
        Intent myIntent = new Intent( view.getContext(), MyActivity.class);
        startActivityForResult(myIntent, 0);
    }
});

I knew I am late to the party but below is the correct way to deal with this, the key is to use InputStreamBody in place of FileBody to upload multi-part file.

   try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost postRequest = new HttpPost("https://someserver.com/api/path/");
        postRequest.addHeader("Authorization",authHeader);
        //don't set the content type here            
        //postRequest.addHeader("Content-Type","multipart/form-data");
        MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);


        File file = new File(filePath);
        FileInputStream fileInputStream = new FileInputStream(file);
        reqEntity.addPart("parm-name", new InputStreamBody(fileInputStream,"image/jpeg","file_name.jpg"));

        postRequest.setEntity(reqEntity);
        HttpResponse response = httpclient.execute(postRequest);

        }catch(Exception e) {
            Log.e("URISyntaxException", e.toString());
   }

Yep, and if you have tried all the above solutions (what's more likely to happen) and none work for you, it may happen that Guzzle is not installed.

Laravel ships mailing tools, by which is required the Guzzle framework, but it won't be installed, and AS OF the documentation, will have to install it manually: https://laravel.com/docs/master/mail#driver-prerequisites

composer require guzzlehttp/guzzle

You must write schema name and table name in qutotation mark. As below:

select * from "schemaName"."tableName";

Use jQuery. You need to capture the click event and then go on to the website.

$("#myHref").on('click', function() {_x000D_
  alert("inside onclick");_x000D_
  window.location = "http://www.google.com";_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<a href="#" id="myHref">Click me</a>

If you use Pycharm, renaming an app is very easy with refactoring(Shift+F6 default) for all project files.
But make sure you delete the __pycache__ folders in the project directory & its sub-directories. Also be careful as it also renames comments too which you can exclude in the refactor preview window it will show you.
And you'll have to rename OldNameConfig(AppConfig): in apps.py of your renamed app in addition.

If you do not want to lose data of your database, you'll have to manually do it with query in database like the aforementioned answer.

Lets assume this code is running in a thread:

private static ReentrantLock lock = new ReentrantLock();

void accessResource() {
    lock.lock();
    if( checkSomeCondition() ) {
        accessResource();
    }
    lock.unlock();
}

Because the thread owns the lock it will allow multiple calls to lock(), so it re-enter the lock. This can be achieved with a reference count so it doesn't has to acquire lock again.

My solution is based on the TechNet article Fun Things You Can Do With the Get-ChildItem Cmdlet.

Get-ChildItem C:\foo | Where-Object {$_.mode -match "d"}

I used it in my script, and it works well.

Once I changed Options -Index to Options +Index in my conf file, I removed the welcome page and restarted services.

$ sudo rm -f /etc/httpd/conf.d/welcome.conf
$ sudo service httpd restart

I was able to see directory listings after that.

For primitive types (including bytes), use System.Buffer.BlockCopy instead of System.Array.Copy. It's faster.

I timed each of the suggested methods in a loop executed 1 million times using 3 arrays of 10 bytes each. Here are the results:

1. New Byte Array using System.Array.Copy - 0.2187556 seconds
2. New Byte Array using System.Buffer.BlockCopy - 0.1406286 seconds
3. IEnumerable<byte> using C# yield operator - 0.0781270 seconds
4. IEnumerable<byte> using LINQ's Concat<> - 0.0781270 seconds

I increased the size of each array to 100 elements and re-ran the test:

1. New Byte Array using System.Array.Copy - 0.2812554 seconds
2. New Byte Array using System.Buffer.BlockCopy - 0.2500048 seconds
3. IEnumerable<byte> using C# yield operator - 0.0625012 seconds
4. IEnumerable<byte> using LINQ's Concat<> - 0.0781265 seconds

I increased the size of each array to 1000 elements and re-ran the test:

1. New Byte Array using System.Array.Copy - 1.0781457 seconds
2. New Byte Array using System.Buffer.BlockCopy - 1.0156445 seconds
3. IEnumerable<byte> using C# yield operator - 0.0625012 seconds
4. IEnumerable<byte> using LINQ's Concat<> - 0.0781265 seconds

Finally, I increased the size of each array to 1 million elements and re-ran the test, executing each loop only 4000 times:

1. New Byte Array using System.Array.Copy - 13.4533833 seconds
2. New Byte Array using System.Buffer.BlockCopy - 13.1096267 seconds
3. IEnumerable<byte> using C# yield operator - 0 seconds
4. IEnumerable<byte> using LINQ's Concat<> - 0 seconds

So, if you need a new byte array, use

byte[] rv = new byte[a1.Length + a2.Length + a3.Length];
System.Buffer.BlockCopy(a1, 0, rv, 0, a1.Length);
System.Buffer.BlockCopy(a2, 0, rv, a1.Length, a2.Length);
System.Buffer.BlockCopy(a3, 0, rv, a1.Length + a2.Length, a3.Length);

But, if you can use an IEnumerable<byte>, DEFINITELY prefer LINQ's Concat<> method. It's only slightly slower than the C# yield operator, but is more concise and more elegant.

IEnumerable<byte> rv = a1.Concat(a2).Concat(a3);

If you have an arbitrary number of arrays and are using .NET 3.5, you can make the System.Buffer.BlockCopy solution more generic like this:

private byte[] Combine(params byte[][] arrays)
{
    byte[] rv = new byte[arrays.Sum(a => a.Length)];
    int offset = 0;
    foreach (byte[] array in arrays) {
        System.Buffer.BlockCopy(array, 0, rv, offset, array.Length);
        offset += array.Length;
    }
    return rv;
}

*Note: The above block requires you adding the following namespace at the the top for it to work.

using System.Linq;

To Jon Skeet's point regarding iteration of the subsequent data structures (byte array vs. IEnumerable<byte>), I re-ran the last timing test (1 million elements, 4000 iterations), adding a loop that iterates over the full array with each pass:

1. New Byte Array using System.Array.Copy - 78.20550510 seconds
2. New Byte Array using System.Buffer.BlockCopy - 77.89261900 seconds
3. IEnumerable<byte> using C# yield operator - 551.7150161 seconds
4. IEnumerable<byte> using LINQ's Concat<> - 448.1804799 seconds

The point is, it is VERY important to understand the efficiency of both the creation and the usage of the resulting data structure. Simply focusing on the efficiency of the creation may overlook the inefficiency associated with the usage. Kudos, Jon.

If you are using python 2.7 or later, the easiest way to do this is to use the subprocess.check_output() command. Here is an example:

output = subprocess.check_output('ls')

To also redirect stderr you can use the following:

output = subprocess.check_output('ls', stderr=subprocess.STDOUT)

In the case that you want to pass parameters to the command, you can either use a list or use invoke a shell and use a single string.

output = subprocess.check_output(['ls', '-a'])
output = subprocess.check_output('ls -a', shell=True)

Simplified example (with counter):

With Me.lstbox
    .ColumnCount = 2
    .ColumnWidths = "60;60"
    .AddItem
    .List(i, 0) = Company_ID
    .List(i, 1) = Company_name 
    i = i + 1

end with

Make sure to start the counter with 0, not 1 to fill up a listbox.

var str = 'Dude, he totally said that "You Rock!"';
var var1 = str.replace(/\"/g,"\\\"");
alert(var1);

Building on @Pvl's answer, you can include type safety on your returned value as well if you use overrides:

function dig<
  T,
  K1 extends keyof T
  >(obj: T, key1: K1): T[K1];

function dig<
  T,
  K1 extends keyof T,
  K2 extends keyof T[K1]
  >(obj: T, key1: K1, key2: K2): T[K1][K2];

function dig<

  K1 extends keyof T,
  K2 extends keyof T[K1],
  K3 extends keyof T[K1][K2]
  >(obj: T, key1: K1, key2: K2, key3: K3): T[K1][K2][K3];

function dig<

  T[K1][K2][K3][K4][K5] {
    let value: any = obj && obj[key1];

    if (key2) {
      value = value && value[key2];
    }

    if (key3) {
      value = value && value[key3];

You can reduce the server-side load by performing this logic client-side. View source on some Digg pages for reference. They have the server emit an epoch time value that gets processed by Javascript. This way you don't need to manage the end user's time zone. The new server-side code would be something like:

public string GetRelativeTime(DateTime timeStamp)
{
    return string.Format("<script>printdate({0});</script>", timeStamp.ToFileTimeUtc());
}

You could even add a NOSCRIPT block there and just perform a ToString().

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

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

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

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

This approaches uses string concatenation to produce a statement with all tables and their counts dynamically, like the example(s) given in the original question:

          SELECT COUNT(*) AS Count,'[dbo].[tbl1]' AS TableName FROM [dbo].[tbl1]
UNION ALL SELECT COUNT(*) AS Count,'[dbo].[tbl2]' AS TableName FROM [dbo].[tbl2]
UNION ALL SELECT...

Finally this is executed with EXEC:

DECLARE @cmd VARCHAR(MAX)=STUFF(
                    (
                        SELECT 'UNION ALL SELECT COUNT(*) AS Count,''' 
                              + QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME) 
                              + ''' AS TableName FROM ' + QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME)
                        FROM INFORMATION_SCHEMA.TABLES AS t
                        WHERE TABLE_TYPE='BASE TABLE'
                        FOR XML PATH('')
                    ),1,10,'');
EXEC(@cmd);

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

_{P.S. KVISH answer translated to Swift 4.x with renaming the functions as I am specifically using this snippet for the iOS app.}

on ubuntu 18.04 ( virtualenv, python.3.6.x), the following reload snippet solved the problem for me:

main.py

import my_module  # my_module.py
from importlib import reload # reload 
reload(my_module)

print(my_module)
print(my_modeule.hello())

where:

|--main.py    
|--my_module.py

Checksum all files, including both content and their filenames

grep -ar -e . /your/dir | md5sum | cut -c-32

Same as above, but only including *.py files

grep -ar -e . --include="*.py" /your/dir | md5sum | cut -c-32

You can also follow symlinks if you want

grep -aR -e . /your/dir | md5sum | cut -c-32

Other options you could consider using with grep

-s, --no-messages         suppress error messages
-D, --devices=ACTION      how to handle devices, FIFOs and sockets;
-Z, --null                print 0 byte after FILE name
-U, --binary              do not strip CR characters at EOL (MSDOS/Windows)

Data view is good Feature of data table . We can filter the data table as per our requirements using data view . Below Functions is After binding data table to list box data source then filter by text box control . ( this condition you can change as per your needs .Contains(txtSearch.Text.Trim()) )

Private Sub BindClients()

   okcl = 0

    sql = "Select * from Client Order By cname"        
    Dim dacli As New SqlClient.SqlDataAdapter
    Dim cmd As New SqlClient.SqlCommand()
    cmd.CommandText = sql
    cmd.CommandType = CommandType.Text
    dacli.SelectCommand = cmd
    dacli.SelectCommand.Connection = Me.sqlcn
    Dim dtcli As New DataTable
    dacli.Fill(dtcli)
    dacli.Fill(dataTableClients)
    lstboxc.DataSource = dataTableClients
    lstboxc.DisplayMember = "cname"
    lstboxc.ValueMember = "ccode"
    okcl = 1

    If dtcli.Rows.Count > 0 Then
        ccode = dtcli.Rows(0)("ccode")
        Call ClientDispData1()
    End If
End Sub

Private Sub FilterClients()        

    Dim query As EnumerableRowCollection(Of DataRow) = From dataTableClients In 
    dataTableClients.AsEnumerable() Where dataTableClients.Field(Of String) 
    ("cname").Contains(txtSearch.Text.Trim()) Order By dataTableClients.Field(Of 
    String)("cname") Select dataTableClients

    Dim dataView As DataView = query.AsDataView()
    lstboxc.DataSource = dataView
    lstboxc.DisplayMember = "cname"
    lstboxc.ValueMember = "ccode"
    okcl = 1
    If dataTableClients.Rows.Count > 0 Then
        ccode = dataTableClients.Rows(0)("ccode")
        Call ClientDispData1()

If you have to use an image as the transparent background, you might be able to work around it using a pseudo element:

html

<div class="wrap"> 
   <p>I have 100% opacity</p>  
</div>

css

.wrap, .wrap > * {
  position: relative;
}
.wrap:before {
  content: " ";
  opacity: 0.2;
  background: url("http://placehold.it/100x100/FF0000") repeat;     
  position: absolute;
  width: 100%;
  height: 100%;
}

Try parent_window.maxsize(x,x); to set the maximum size. It shouldn't get larger even if you set the background, etc.

Edit: use parent_window.minsize(x,x) also to set it to a constant size!

if someones is interested you can delete the form node from the DOM after the submission and it won't be there using the inspector.

I tried to use dplyr::rename and I get an error:

occ_5d <- dplyr::rename(occ_5d, rowname='code_5d')
Error: Unknown column `code_5d` 
Call `rlang::last_error()` to see a backtrace

I instead used the base R function which turns out to be quite simple and effective:

names(occ_5d)[1] = "code_5d"

If scrollHeight could be trusted, then:

textarea.onkeyup=function() {
  this.style.height='';
  this.rows=this.value.split('\n').length;
  this.style.height=this.scrollHeight+'px';
}

Just access the Priority property of the object returned from the pipeline:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

(This won't work if Get-WSManInstance returns multiple objects.²)

For the second question: to get two properties there are several options, problably the simplest is to have have one variable* containing an object with two separate properties:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use, assuming only one process:

$var.Priority

and

$var.ProcessID

If there are multiple processes $var will be an array which you can index, so to get the properties of the first process (using the array literal syntax @(...) so it is always a collection¹):

$var = @(Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use:

$var[0].Priority
$var[0].ProcessID

¹ PowerShell helpfully for the command line, but not so helpfully in scripts has some extra logic when assigning the result of a pipeline to a variable: if no objects are returned then set $null, if one is returned then that object is assigned, otherwise an array is assigned. Forcing an array returns an array with zero, one or more (respectively) elements.

² This changes in PowerShell V3 (at the time of writing in Release Candidate), using a member property on an array of objects will return an array of the value of those properties.

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

Right click the table you want to export and select "Select All Rows"

Right click the results window and select "Save Results As..."

In case of a multi-value return function you can't refer to fields or methods of a specific value of the result when calling the function.

And if one of them is an error, it's there for a reason (which is the function might fail) and you should not bypass it because if you do, your subsequent code might also fail miserably (e.g. resulting in runtime panic).

However there might be situations where you know the code will not fail in any circumstances. In these cases you can provide a helper function (or method) which will discard the error (or raise a runtime panic if it still occurs).
This can be the case if you provide the input values for a function from code, and you know they work.
Great examples of this are the template and regexp packages: if you provide a valid template or regexp at compile time, you can be sure they can always be parsed without errors at runtime. For this reason the template package provides the Must(t *Template, err error) *Template function and the regexp package provides the MustCompile(str string) *Regexp function: they don't return errors because their intended use is where the input is guaranteed to be valid.

Examples:

// "text" is a valid template, parsing it will not fail
var t = template.Must(template.New("name").Parse("text"))

// `^[a-z]+\[[0-9]+\]$` is a valid regexp, always compiles
var validID = regexp.MustCompile(`^[a-z]+\[[0-9]+\]$`)

Back to your case

IF you can be certain Get() will not produce error for certain input values, you can create a helper Must() function which would not return the error but raise a runtime panic if it still occurs:

func Must(i Item, err error) Item {
    if err != nil {
        panic(err)
    }
    return i
}

But you should not use this in all cases, just when you're sure it succeeds. Usage:

val := Must(Get(1)).Value

Alternative / Simplification

You can even simplify it further if you incorporate the Get() call into your helper function, let's call it MustGet:

func MustGet(value int) Item {
    i, err := Get(value)
    if err != nil {
        panic(err)
    }
    return i
}

Usage:

val := MustGet(1).Value

On a Windows 10 x64 machine, I made the command prompt display non-English characters by:

Open an elevated command prompt (run CMD.EXE as administrator). Query your registry for available TrueType fonts to the console by:

    REG query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont"

You'll see an output like:

    0    REG_SZ    Lucida Console
    00    REG_SZ    Consolas
    936    REG_SZ    *???
    932    REG_SZ    *MS ????

Now we need to add a TrueType font that supports the characters you need like Courier New. We do this by adding zeros to the string name, so in this case the next one would be "000":

    REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont" /v 000 /t REG_SZ /d "Courier New"

Now we implement UTF-8 support:

    REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 65001 /f

Set default font to "Courier New":

    REG ADD HKCU\Console /v FaceName /t REG_SZ /d "Courier New" /f

Set font size to 20:

    REG ADD HKCU\Console /v FontSize /t REG_DWORD /d 20 /f

Enable quick edit if you like:

    REG ADD HKCU\Console /v QuickEdit /t REG_DWORD /d 1 /f

There's an easier way, by extending an empty LatLngBounds rather than creating one explicitly from two points. (See this question for more details)

Should look something like this, added to your code:

//create empty LatLngBounds object
var bounds = new google.maps.LatLngBounds();
var infowindow = new google.maps.InfoWindow();    

for (i = 0; i < locations.length; i++) {  
  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map
  });

  //extend the bounds to include each marker's position
  bounds.extend(marker.position);

  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infowindow.setContent(locations[i][0]);
      infowindow.open(map, marker);
    }
  })(marker, i));
}

//now fit the map to the newly inclusive bounds
map.fitBounds(bounds);

//(optional) restore the zoom level after the map is done scaling
var listener = google.maps.event.addListener(map, "idle", function () {
    map.setZoom(3);
    google.maps.event.removeListener(listener);
});

This way, you can use an arbitrary number of points, and don't need to know the order beforehand.

GROUP BY 1

I've never known GROUP BY to support using ordinals, only ORDER BY. Either way, only MySQL supports GROUP BY's not including all columns without aggregate functions performed on them. Ordinals aren't recommended practice either because if they're based on the order of the SELECT - if that changes, so does your ORDER BY (or GROUP BY if supported).

There's no need to run GROUP BY on the contents when you're using UNION - UNION ensures that duplicates are removed; UNION ALL is faster because it doesn't - and in that case you would need the GROUP BY...

Your query only needs to be:

SELECT a.id,
       a.time
  FROM dbo.TABLE_A a
UNION
SELECT b.id,
       b.time
  FROM dbo.TABLE_B b

Instead of myFile.js write your files like myFile.mjs. This extension comes with all the goodies of es6, but I mean I recommend you to you webpack and Babel

Permanently authenticating with Git repositories

Run the following command to enable credential caching:

$ git config credential.helper store
$ git push https://github.com/owner/repo.git

Username for 'https://github.com': <USERNAME>
Password for 'https://[email protected]': <PASSWORD>

You should also specify caching expire,

git config --global credential.helper 'cache --timeout 7200'

After enabling credential caching, it will be cached for 7200 seconds (2 hour).

I want to work with exec_query of the ActiveRecord class, because it returns the mapping of the query transforming into object, so it gets very practical and productive to iterate with the objects when the subject is Raw SQL.

Example:

values = ActiveRecord::Base.connection.exec_query("select * from clients")
p values

and return this complete query:

[{"id": 1, "name": "user 1"}, {"id": 2, "name": "user 2"}, {"id": 3, "name": "user 3"}]

To get only list of values

p values.rows

[[1, "user 1"], [2, "user 2"], [3, "user 3"]]

To get only fields columns

p values.columns

["id", "name"]

Make sure to check the python version you are working on if it is 2 then only pip install works If it is 3. something then make sure to use pip3 install

With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:

print *(myVector._M_impl._M_start)@myVector.size()

To print only the first N elements, do:

print *(myVector._M_impl._M_start)@N

Explanation

This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:

myVector._M_impl._M_start 

And the GDB command to print N elements of an array starting at pointer P is:

print P@N

Or, in a short form (for a standard .gdbinit):

p P@N

return n from main is equivalent to exit(n).

The valid returned is the rest of your program. It's meaning is OS dependent. On unix, 0 means normal termination and non-zero indicates that so form of error forced your program to terminate without fulfilling its intended purpose.

It's unusual that your example returns 0 (normal termination) when it seems to have run out of memory.

In the nav go View => Layout => Columns:2 (alt+shift+2) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py)

It appears you can also reopen the file using the command File -> New View into File which will open the current file in a new tab

Set force Portrait or Landscape mode, Add lines respectively.

Import below line:

import android.content.pm.ActivityInfo;

Add Below line just above setContentView(R.layout.activity_main);

For Portrait:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//Set Portrait

For Landscap:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//Set Landscape

This will definitely work.

I just delete settings.lic file from project and start working!

Sorry for answering so late.

I figured an answer alike to @xlm 's:

task run (type: JavaExec, dependsOn: classes){
    if(project.hasProperty('myargs')){
        args(myargs.split(','))
    }
    description = "Secure algorythm testing"
    main = "main.Test"
    classpath = sourceSets.main.runtimeClasspath
}

And invoke like:

gradle run -Pmyargs=-d,s

You can use JSONPath

Doing something like this:

results = JSONPath(null, TestObj, "$..[?(@.id=='A')]")

Note that JSONPath returns an array of results

(I have not tested the expression "$..[?(@.id=='A')]" btw. Maybe it needs to be fine-tuned with the help of a browser console)

There is no way to rename a folder through the GUI, the fastest (and easiest if you like GUI) way to achieve this is to perform an plain old copy. To achieve this: create the new folder on S3 using the GUI, get to your old folder, select all, mark "copy" and then navigate to the new folder and choose "paste". When done, remove the old folder.

This simple method is very fast because it is copies from S3 to itself (no need to re-upload or anything like that) and it also maintains the permissions and metadata of the copied objects like you would expect.

I would ALWAYS go with both the alt and the title attributes. Many developers have been using this pattern now for over 20 years to deal with IE and other issues. So this is not new knowledge. Its just been rediscovered by new developers that didn't bother to learn from the past.

In addition, in HTML5 you should start using the new HTML5 picture element wrapped in figure with full WPA-ARIA attributes for greater accessibility, as well as support of assistive technologies, screen readers, and the like. Because this element is not supported in many older browsers...BUT degrades gracefully...I recommend the following HTML design pattern now for images in HTML:

<figure aria-labelledby="picturecaption2">
    <picture id="picture2">
        <source srcset="image.webp" type="image/webp" media="(min-width: 800px)" />
        <source srcset="image.gif" type="image/gif" />
        <img id="image2" style="height:auto;max-width: 100%;" src="image.jpg" width="255" height="200" alt="image:The World Wide Web" title="The World Wide Web" loading="lazy" no-referrer="no-referrer" onerror="this.onerror=null;" />
    </picture>
    <figcaption id="picturecaption2"><small>"My Cool Picture" [<a href="http://creativecommons.org/licenses/" target="_blank">A License</a>] , via <a href="https://commons.wikimedia.org/wiki/" target="_blank">Wikimedia Commons</a></small></figcaption>
</figure>

The code above has many extra "goodies" beside alt and title, including ARIA attributes, support for WebP, a media query supporting higher resolution imagery, and a nice fallback pattern supporting older image formats. It shows a fully decorated image example that uses new technologies while still supporting old ones with progressive design patterns.

REMEMBER...ALWAYS SUPPORT THE OLD BROWSERS!

Vinay (above) gave an effective work-around. What's actually causing the button's OnClick event to not work following the OnClientClick event function is that MS has defined it where, once the button is disabled (in the function called by the OnClientClick event), the button "honors" this by not trying to complete the button's activity by calling the OnClick event's defined method.

I struggled several hours trying to figure this out. Once I removed the statement to disable the submit button (that was inside the OnClientClick function), the OnClick method was called with no further problem.

Microsoft, if you're listening, once the button is clicked it should complete it's assigned activity even if it is disabled part of the way through this activity. As long as it is not disabled when it is clicked, it should complete all assigned methods.

You should create new SSH key set for that Docker image, as you probably don't want to embed there your own private key. To make it work, you'll have to add that key to deployment keys in your git repository. Here's complete recipe:

1. Generate ssh keys with ssh-keygen -q -t rsa -N '' -f repo-key which will give you repo-key and repo-key.pub files.

2. Add repo-key.pub to your repository deployment keys.
   On GitHub, go to [your repository] -> Settings -> Deploy keys

3. Add something like this to your Dockerfile:

   ADD repo-key /
   RUN \
     chmod 600 /repo-key && \  
     echo "IdentityFile /repo-key" >> /etc/ssh/ssh_config && \  
     echo -e "StrictHostKeyChecking no" >> /etc/ssh/ssh_config && \  
     // your git clone commands here...
   

Note that above switches off StrictHostKeyChecking, so you don't need .ssh/known_hosts. Although I probably like more the solution with ssh-keyscan in one of the answers above.

I think i have the easiest approach... on pressing new in B..

Intent intent = new Intent(B.this, A.class);
intent.putExtra("NewClicked", true);
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

and in A get it

  if (getIntent().getBooleanExtra("NewClicked", false)) {
        finish();// finish yourself and make a create a new Instance of yours.
      Intent intent = new Intent(A.this,A.class);
      startActivity(intent);
    }

I would use the operator[].

map <char, int> m1;

m1['G'] ++;  // If the element 'G' does not exist then it is created and 
             // initialized to zero. A reference to the internal value
             // is returned. so that the ++ operator can be applied.

// If 'G' did not exist it now exist and is 1.
// If 'G' had a value of 'n' it now has a value of 'n+1'

So using this technique it becomes really easy to read all the character from a stream and count them:

map <char, int>                m1;
std::ifstream                  file("Plop");
std::istreambuf_iterator<char> end;

for(std::istreambuf_iterator<char> loop(file); loop != end; ++loop)
{
    ++m1[*loop]; // prefer prefix increment out of habbit
}

this will remove the trailing commas and spaces

var str = ",'first string','more','even more'";
var trim = str.replace(/(^\s*,)|(,\s*$)/g, '');
