And here is a bigint version of the same

DECLARE @ts BIGINT 
SET @ts = CAST(CAST(getdate() AS TIMESTAMP) AS BIGINT)
SELECT @ts

In short: It's a shorthand notation for a mathematical hack.

Long explanation:

You can't do a cross product with vectors in 2D space. The operation is not defined there.

However, often it is interesting to evaluate the cross product of two vectors assuming that the 2D vectors are extended to 3D by setting their z-coordinate to zero. This is the same as working with 3D vectors on the xy-plane.

If you extend the vectors that way and calculate the cross product of such an extended vector pair you'll notice that only the z-component has a meaningful value: x and y will always be zero.

That's the reason why the z-component of the result is often simply returned as a scalar. This scalar can for example be used to find the winding of three points in 2D space.

From a pure mathematical point of view the cross product in 2D space does not exist, the scalar version is the hack and a 2D cross product that returns a 2D vector makes no sense at all.

You can use Django's built-in validators—

from django.db.models import IntegerField, Model
from django.core.validators import MaxValueValidator, MinValueValidator

class CoolModelBro(Model):
    limited_integer_field = IntegerField(
        default=1,
        validators=[
            MaxValueValidator(100),
            MinValueValidator(1)
        ]
     )

Edit: When working directly with the model, make sure to call the model full_clean method before saving the model in order to trigger the validators. This is not required when using ModelForm since the forms will do that automatically.

I found myself in a unique situation where instanceof could not be used (specifically namespaced traits) and I needed the short name in the most efficient way possible so I've done a little benchmark of my own. It includes all the different methods & variations from the answers in this question.

$bench = new \xori\Benchmark(1000, 1000);     # https://github.com/Xorifelse/php-benchmark-closure
$shell = new \my\fancy\namespace\classname(); # Just an empty class named `classname` defined in the `\my\fancy\namespace\` namespace

$bench->register('strrpos', (function(){
    return substr(static::class, strrpos(static::class, '\\') + 1);
})->bindTo($shell));

$bench->register('safe strrpos', (function(){
    return substr(static::class, ($p = strrpos(static::class, '\\')) !== false ? $p + 1 : 0);
})->bindTo($shell));

$bench->register('strrchr', (function(){
    return substr(strrchr(static::class, '\\'), 1);
})->bindTo($shell));

$bench->register('reflection', (function(){
    return (new \ReflectionClass($this))->getShortName();
})->bindTo($shell));

$bench->register('reflection 2', (function($obj){
    return $obj->getShortName();
})->bindTo($shell), new \ReflectionClass($shell));

$bench->register('basename', (function(){
    return basename(str_replace('\\', '/', static::class));
})->bindTo($shell));

$bench->register('explode', (function(){
    $e = explode("\\", static::class);
    return end($e);
})->bindTo($shell));

$bench->register('slice', (function(){
    return join('',array_slice(explode('\\', static::class), -1));
})->bindTo($shell));    

print_r($bench->start());

A list of the of the entire result is here but here are the highlights:

• If you're going to use reflection anyways, using $obj->getShortName() is the fastest method however; using reflection only to get the short name it is almost the slowest method.
• 'strrpos' can return a wrong value if the object is not in a namespace so while 'safe strrpos' is a tiny bit slower I would say this is the winner.
• To make 'basename' compatible between Linux and Windows you need to use str_replace() which makes this method the slowest of them all.

A simplified table of results, speed is measured compared to the slowest method:

+-----------------+--------+
| registered name | speed  |
+-----------------+--------+
| reflection 2    | 70.75% |
| strrpos         | 60.38% |
| safe strrpos    | 57.69% |
| strrchr         | 54.88% |
| explode         | 46.60% |
| slice           | 37.02% |
| reflection      | 16.75% |
| basename        | 0.00%  |
+-----------------+--------+

For generating the patches from the topmost commits from a specific sha1 hash:

git format-patch -<n> <SHA1>

The last 10 patches from head in a single patch file:

git format-patch -10 HEAD --stdout > 0001-last-10-commits.patch

you want

import os
os.getcwd()
os.chdir('..')

I disagree with the advice given here - even the reference for the accepted answer concludes:

You can of course use query string parameters with HTTPS, but don’t use them for anything that could present a security problem. For example, you could safely use them to identity part numbers or types of display like ‘accountview’ or ‘printpage’, but don’t use them for passwords, credit card numbers or other pieces of information that should not be publicly available.

So, no they aren't really safe...!

zip creates a new list, filled with tuples containing elements from the iterable arguments:

>>> zip ([1,2],[3,4])
[(1,3), (2,4)]

I expect what you try to so is create a tuple where each element is a list.

For me onKeyPress the e.keyCode is always 0, but e.charCode has correct value. If used onKeyDown the correct code in e.charCode.

var Title = React.createClass({
    handleTest: function(e) {
      if (e.charCode == 13) {
        alert('Enter... (KeyPress, use charCode)');
      }
      if (e.keyCode == 13) {
        alert('Enter... (KeyDown, use keyCode)');
      }
    },
    render: function() {
      return(
        <div>
          <textarea onKeyPress={this.handleTest} />
        </div>
      );
    }
  });

I've read a few things about this and unfortunately the ANDROID_ID should not be relied on for uniquely identifying an individual device.

It doesn't seem to be enforced in Android compliance requirements and so manufacturers seem to implement it the way they choose including some using it more as a 'model' ID etc.

Also, be aware that even if a manufacturer has written a generator to make it a UUID (for example), it's not guaranteed to survive a factory reset.

In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds file. Not so for Rda

> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)

## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5

## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to  <environment: R_GlobalEnv> 
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values. 
> x
[1] 1 2 3 4 5

query runs a standard SQL statement and requires you to properly escape all data to avoid SQL Injections and other issues.

execute runs a prepared statement which allows you to bind parameters to avoid the need to escape or quote the parameters. execute will also perform better if you are repeating a query multiple times. Example of prepared statements:

$sth = $dbh->prepare('SELECT name, colour, calories FROM fruit
    WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories);
$sth->bindParam(':colour', $colour);
$sth->execute();
// $calories or $color do not need to be escaped or quoted since the
//    data is separated from the query

Best practice is to stick with prepared statements and execute for increased security.

See also: Are PDO prepared statements sufficient to prevent SQL injection?

You should use DecimalFormat("0.#")

For 4.3000

Double price = 4.3000;
DecimalFormat format = new DecimalFormat("0.#");
System.out.println(format.format(price));

output is:

4.3

In case of 5.000 we have

Double price = 5.000;
DecimalFormat format = new DecimalFormat("0.#");
System.out.println(format.format(price));

And the output is:

5

You don't need to send messages.

Add an event to the one form and an event handler to the other. Then you can use a third project which references the other two to attach the event handler to the event. The two DLLs don't need to reference each other for this to work.

I created a new AutomapperProfile class. It extends Profile. We have over 100 projects in our solution. Many projects have an AutomapperProfile class, but this one was new to this existing project. However, I did find what I had to do to fix this issue for us. There is a Binding project. Within the Initialization there is this code:

var mappingConfig = new List<Action<IConfiguration>>();

// Initialize the Automapper Configuration for all Known Assemblies
mappingConfig.AddRange( new List<Action<IConfiguration>>
{
   ConfigureProfilesInAssemblyOfType<Application.Administration.AutomapperProfile>,
   //...

I had to add ConfigureProfilesInAssemblyOfType<MyNewNamespace.AutomapperProfile>

Note that ConfigureProfilesInAssemblyOfType looks like this:

    private static void ConfigureProfilesInAssemblyOfType<T>( IConfiguration configuration )
    {
        var log = LogProvider.Get( typeof (AutomapperConfiguration) );

        // The Automapper Profile Type
        var automapperProfileType = typeof (Profile);

        // The Assembly containing the type
        var assembly = typeof (T).Assembly;
        log.Debug( "Scanning " + assembly.FullName );

        // Configure any Profile classes found in the assembly containing the type.
        assembly.GetTypes()
            .Where( automapperProfileType.IsAssignableFrom ).ToList()
            .ForEach( x =>
            {
                log.Debug( "Adding Profile '" + x.FullName + "'" );
                configuration.AddProfile( Activator.CreateInstance( x ) as Profile );
            } );
    }

Actually "Sheet1" object / code name can be changed. In VBA, click on Sheet1 in Excel Objects list. In the properties window, you can change Sheet1 to say rng.

Then you can reference rng as a global object without having to create a variable first. So debug.print rng.name works just fine. No more Worksheets("rng").name.

Unlike the tab, the object name has same restrictions as other variables (i.e. no spaces).

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

/system/bin/bugmailer.sh must be deleted/renamed.

There should be a folder on your SD card called "bug reports".

Here is another relatively simple solution that:

• does not use dirname() (which does not work as expected on one level arguments like "file.txt" or relative parents like "..")
• does not use abspath() (avoiding any assumptions about the current working directory) but instead preserves the relative character of paths

it just uses normpath and join:

def parent(p):
    return os.path.normpath(os.path.join(p, os.path.pardir))

# Example:
for p in ['foo', 'foo/bar/baz', 'with/trailing/slash/', 
        'dir/file.txt', '../up/', '/abs/path']:
    print parent(p)

Result:

.
foo/bar
with/trailing
dir
..
/abs

If it's a percentage width, then yes, it is respected. As Martin pointed out, things break down when you get to fractional pixels, but if your percentage values yield integer pixel value (e.g. 50.5% of 200px in the example) you'll get sensible, expected behaviour.

Edit: I've updated the example to show what happens to fractional pixels (in Chrome the values are truncated, so 50, 50.5 and 50.6 all show the same width).

I always have to look this one up time and time again, so here is my answer.

Asserting multiple method calls on different objects of the same class

Suppose we have a heavy duty class (which we want to mock):

In [1]: class HeavyDuty(object):
   ...:     def __init__(self):
   ...:         import time
   ...:         time.sleep(2)  # <- Spends a lot of time here
   ...:     
   ...:     def do_work(self, arg1, arg2):
   ...:         print("Called with %r and %r" % (arg1, arg2))
   ...:  

here is some code that uses two instances of the HeavyDuty class:

In [2]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(13, 17)
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(23, 29)
   ...:    

Now, here is a test case for the heavy_work function:

In [3]: from unittest.mock import patch, call
   ...: def test_heavy_work():
   ...:     expected_calls = [call.do_work(13, 17),call.do_work(23, 29)]
   ...:     
   ...:     with patch('__main__.HeavyDuty') as MockHeavyDuty:
   ...:         heavy_work()
   ...:         MockHeavyDuty.return_value.assert_has_calls(expected_calls)
   ...:  

We are mocking the HeavyDuty class with MockHeavyDuty. To assert method calls coming from every HeavyDuty instance we have to refer to MockHeavyDuty.return_value.assert_has_calls, instead of MockHeavyDuty.assert_has_calls. In addition, in the list of expected_calls we have to specify which method name we are interested in asserting calls for. So our list is made of calls to call.do_work, as opposed to simply call.

Exercising the test case shows us it is successful:

In [4]: print(test_heavy_work())
None

If we modify the heavy_work function, the test fails and produces a helpful error message:

In [5]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(113, 117)  # <- call args are different
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(123, 129)  # <- call args are different
   ...:     

In [6]: print(test_heavy_work())
---------------------------------------------------------------------------
(traceback omitted for clarity)

AssertionError: Calls not found.
Expected: [call.do_work(13, 17), call.do_work(23, 29)]
Actual: [call.do_work(113, 117), call.do_work(123, 129)]

Asserting multiple calls to a function

To contrast with the above, here is an example that shows how to mock multiple calls to a function:

In [7]: def work_function(arg1, arg2):
   ...:     print("Called with args %r and %r" % (arg1, arg2))

In [8]: from unittest.mock import patch, call
   ...: def test_work_function():
   ...:     expected_calls = [call(13, 17), call(23, 29)]    
   ...:     with patch('__main__.work_function') as mock_work_function:
   ...:         work_function(13, 17)
   ...:         work_function(23, 29)
   ...:         mock_work_function.assert_has_calls(expected_calls)
   ...:    

In [9]: print(test_work_function())
None

There are two main differences. The first one is that when mocking a function we setup our expected calls using call, instead of using call.some_method. The second one is that we call assert_has_calls on mock_work_function, instead of on mock_work_function.return_value.

I faced the same problem.

Just removed the server from configuration and added it back after restarting eclipse by adding it to the server runtime environment.

This is the only script I can get to play nice with bash on MacOS. I combined and edited snippets from the following two links:

ls command: how can I get a recursive full-path listing, one line per file?

http://www.linuxquestions.org/questions/linux-general-1/is-there-a-bash-command-for-picking-a-random-file-678687/

#!/bin/bash

# Reads a given directory and picks a random file.

# wanted to parametrize it.

# spaces do not break our script.
IFS='
'

if [[ -d "${DIR}" ]]
then
  # Runs ls on the given dir, and dumps the output into a matrix,
  # it uses the new lines character as a field delimiter, as explained above.
  #  file_matrix=($(ls -LR "${DIR}"))

  file_matrix=($(ls -R $DIR | awk '; /:$/&&f{s=$0;f=0}; /:$/&&!f{sub(/:$/,"");s=$0;f=1;next}; NF&&f{ print s"/"$0 }'))
  num_files=${#file_matrix[*]}

  # This is the command you want to run on a random file.
  # Change "ls -l" by anything you want, it's just an example.
  ls -l "${file_matrix[$((RANDOM%num_files))]}"

One thing not mentioned in answers is inline element can break among lines while inline-block can't (and obviously block)! So inline elements can be useful to style sentences of text and blocks inside them, but as they can't be padded you can use line-height instead.

<div style="width: 350px">_x000D_
  Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua._x000D_

Suppose you want the value of the first item.

ListBox list = new ListBox();
Console.Write(list.Items[0].Value);

I know this is old but here's a one liner list comprehension:

data = ['word1, 23, 12','word2, 10, 19','word3, 11, 15']

[[int(item) if item.isdigit() else item for item in items.split(', ')] for items in data]

or

[int(item) if item.isdigit() else item for items in data for item in items.split(', ')]

If your listview is also re-sizing then you can use a behavior pattern to re-size the columns to fit the full ListView width. Almost the same as you using grid.column definitions

<ListView HorizontalAlignment="Stretch"
          Behaviours:GridViewColumnResize.Enabled="True">
        <ListViewItem></ListViewItem>
        <ListView.View>
            <GridView>
                <GridViewColumn  Header="Column *"
                                   Behaviours:GridViewColumnResize.Width="*" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBox HorizontalAlignment="Stretch" Text="Example1" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>

See the following link for some examples and link to source code http://lazycowprojects.tumblr.com/post/7063214400/wpf-c-listview-column-width-auto

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

Working for me. SpringBoot.

 import com.alibaba.fastjson.annotation.JSONField;

 @JSONField(format = "yyyy-MM-dd HH:mm:ss")

}

If returning an array works and returning a single object doesn't, you might also try returning your single object as an array containing that single object:

[ { title: "One", key: "1" } ]

that way you are returning a consistent data structure, an array of objects, no matter the data payload.

i see that you've tried wrapping your single object in "parenthesis", and suggest this with example because of course JavaScript treats [ .. ] differently than ( .. )

just how to replace strings :) as i do first arg will be filename second target string third one the string to be replaced instead of targe

public class ReplaceString{
      public static void main(String[] args)throws Exception {
        if(args.length<3)System.exit(0);
        String targetStr = args[1];
        String altStr = args[2];
        java.io.File file = new java.io.File(args[0]);
        java.util.Scanner scanner = new java.util.Scanner(file);
        StringBuilder buffer = new StringBuilder();
        while(scanner.hasNext()){
          buffer.append(scanner.nextLine().replaceAll(targetStr, altStr));
          if(scanner.hasNext())buffer.append("\n");
        }
        scanner.close();
        java.io.PrintWriter printer = new java.io.PrintWriter(file);
        printer.print(buffer);
        printer.close();
      }
    }

I had the same issue on OS X 10.9.1 with python 2.7.5. No issues with WORKON_HOME for me, but I did have to manually add source "/usr/local/bin/virtualenvwrapper.sh" to ~/.bash_profile (or ~/.bashrc in unix) after I ran pip install virtualenvwrapper

@Controller
public class WebController {
@GetMapping("/")

public String homePage() {
    return "index";
  }
}

First of all, input element shouldn't have a closing tag (from http://www.w3.org/TR/html401/interact/forms.html#edef-INPUT : End tag: forbidden ).

Second thing, you need the after(), not append() function.

This is CSS issues. I don't know why @Html.DropDownListFor in Bootstrap 4 doest work. Surely this is class design problem. Anyways the work arround is, if your Dropdown input box has CSS Padding: #px, # px; element then disable it. Hope this will work.

To center the col- we need to use the below code. cols are floater elements besides margin auto. We will also set it to float none,

<body class="container">
    <div class="col-lg-1 col-md-4 centered">
        <img data-src="holder.js/100x100" alt="" />
    </div>
</body>

To center the above col-lg-1 with class of centered, we will write:

.centered {
    float: none;
    margin-left: auto;
    margin-right: auto;
}

To center the content inside the div, use text-align:center,

.centered {
    text-align: center;
}

If you want to center it only on the desktop and larger screen, not on mobile, then use the following media query.

@media (min-width: 768px) {
    .centered {
        float: none;
        margin-left: auto;
        margin-right: auto;
    }
}

And to center the div only on mobile version, use the below code.

@media (max-width: 768px) {
    .centered {
        float: none;
        margin-left: auto;
        margin-right: auto;
    }
}

Like this:

border: 1px solid black;

Why it didn't work? because:

Always declare the border-style (solid in my example) property before the border-width property. An element must have borders before you can change the color.

I'm not really sure this question is approprate here, but you can add a new "Build System" under Tools -> Build System -> New Build System...

As with all configuration in Sublime Text its just JSON, so it should be pretty straight forward. The main thing you are going to want to configure is the "cmd" key/val. Here is the build config for launching chrome on my mac.

{
    "cmd": ["open", "-a", "Google Chrome", "$file"]
}

Save that as Chrome.sublime-build, relaunch Sublime Text and you should see a new Chrome option in the build list. Select it, and then you should be able to launch Chrome with Cmd+B on a Mac (or whatever hotkey you have configured for build, maybe its F7 or Ctrl+B on a Windows machine)

At least this should give you a push in the right direction.

Edit:

Another thing I end up doing a lot in Sublime Text 2 is if you right click inside a document, one of the items in the context menu is Copy File Path, which puts the current file's full path into the clipboard for easy pasting into whatever browser you want.

Sublime Text 3 (linux example) "shell_cmd": "google-chrome '$file'"

if you have parent element than your parent element must have overflow: hidden; property because if your children content is getting oveflowed from parent border than your border will be visible .otherwise your borderradius is working but it is hide by your children content.

.outer {
  width: 200px;
  height: 120px;
  border: 1px solid black;

It will be hard to work in C# without knowing how to work with strings and booleans. But anyway:

        String str = "ABC";
        if (str.Contains('A'))
        { 
            //...
        }

        if (str.Contains("AB"))
        { 
            //...
        }

Just supply literal values in the SELECT:

INSERT INTO TABLE1 (id, col_1, col_2, col_3)
SELECT id, 'data1', 'data2', 'data3'
FROM TABLE2
WHERE col_a = 'something';

A select list can contain any value expression:

But the expressions in the select list do not have to reference any columns in the table expression of the FROM clause; they can be constant arithmetic expressions, for instance.

And a string literal is certainly a value expression.

A value can be reassigned in case of var

 //Variables
 var age = 42
 println(age) //Will print 42
 age = 90
 println(age) //Will Print 90

** the newAge constant cannot be reassigned to a new value. Trying to do so will give a compile time error**

//Constants
let newAge = 92 //Declaring a constant using let
println(newAge) //Will print 92.

If the this value you want is the just the object that you bound the event handler to, then addEventListener() already does that for you. When you do this:

productLineSelect.addEventListener('change', getSelection, false);

the getSelection function will already be called with this set to the object that the event handler was bound to. It will also be passed an argument that represents the event object which has all sorts of object information about the event.

function getSelection(event) {
    // this will be set to the object that the event handler was bound to
    // event is all the detailed information about the event
}

If the desired this value is some other value than the object you bound the event handler to, you can just do this:

var self = this;
productLineSelect.addEventListener('change',function() {
    getSelection(self)
},false);

By way of explanation:

1. You save away the value of this into a local variable in your other event handler.
2. You then create an anonymous function to pass addEventListener.
3. In that anonymous function, you call your actual function and pass it the saved value of this.

I have created a project for basic pinch-zoom that supports Android 2.1+

By using display: inline-block; And more generally when you have a parent (always there is a parent except for html) use display: inline-block; for the inner elements. and to force them to stay in the same line even when the window get shrunk (contracted). Add for the parent the two property:

    white-space: nowrap;
    overflow-x: auto;

here a more formatted example to make it clear:

.parent {
    white-space: nowrap;
    overflow-x: auto;
}

.children {
   display: inline-block;
   margin-left: 20px; 
}

For this example particularly, you can apply the above as fellow (i'm supposing the parent is body. if not you put the right parent), you can also like change the html and add a parent for them if it's possible.

body { /*body may pose problem depend on you context, there is no better then have a specific parent*/
        white-space: nowrap;
        overflow-x: auto;
 }

#element1, #element2{ /*you can like put each one separately, if the margin for the first element is not wanted*/
   display: inline-block;
   margin-left: 10px; 
}

keep in mind that white-space: nowrap; and overlow-x: auto; is what you need to force them to be in one line. white-space: nowrap; disable wrapping. And overlow-x:auto; to activate scrolling, when the element get over the frame limit.

The error indicates that the DLL is either not a COM DLL or it's corrupt. If it's not a COM DLL and not being used as a COM DLL by an application then there is no need to register it.
From what you say in your question (the service is not registered) it seems that we are talking about a service not correctly installed. I will try to reinstall the application.

Great answers from a couple of years ago. Now Bitbucket has made it easier.

Tag the Commit you want to download (as mentioned in answer by Rudy Matela).

Then head over to Downloads and click the "Tags" tab and you'll get multiple options for download.

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target
};

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

Use Point data type to store Longitude and Latitude in a single column:

CREATE TABLE table_name (
    id integer NOT NULL,
    name text NOT NULL,
    location point NOT NULL,
    created_on timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
    CONSTRAINT table_name_pkey PRIMARY KEY (id)
)

Create an Indexing on a 'location' column :

CREATE INDEX ON table_name USING GIST(location);

GiST index is capable of optimizing “nearest-neighbor” search :

SELECT * FROM table_name ORDER BY location <-> point '(-74.013, 40.711)' LIMIT 10;

Note: The point first element is longitude and the second element is latitude.

For more info check this Query Operators.

This is as simple as this.

window.open('_link is here_', 'name'); 

Function description:

name is a name of the window. Following names are supported:

• _blank - URL is loaded into a new tab. This is default.
• _parent - URL is loaded into the parent frame
• _self - URL replaces the current page
• _top - URL replaces any framesets that may be loaded

One common use is in the singleton pattern where you want only one instance of the class to exist. In that case, you can provide a static method which does the instantiation of the object. This way the number of objects instantiated of a particular class can be controlled.

One of my projects in my solution was set to Release mode. I changed it back to Debug mode, and the breakpoints are hitting now.

To set Maven Proxy :

Edit the proxies session in your ~/.m2/settings.xml file. If you cant find the file, create one.

        <active>true</active>
        <protocol>http</protocol>
        <host>your-proxy-host</host>
        <port>your-proxy-port</port>
        <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
<proxy>

You don't need to write a converter, just do this in your handler/codebehind:

int i = Convert.ToInt32(txtMyTextBox.Text);

OR

int i = int.Parse(txtMyTextBox.Text);

The Text property of your textbox is a String type, so you have to perform the conversion in the code.

Try to disable ModSecurity from your cPanel. Log into your cPanel. Find the category "Security". There you can find ModSecurity link.Click on it and disable it for the domain you are facing the 403 error.

Some 403 errors can be solved by this method too. Go to the wordpress dashboard, settings>permalink and just click save.

Hope this helped. :)

In many cases, I believe @allcaps's answer works well.

However, sometimes it is necessary to actually rename an app, e.g. to improve code readability or prevent confusion.

Most of the other answers involve either manual database manipulation or tinkering with existing migrations, which I do not like very much.

As an alternative, I like to create a new app with the desired name, copy everything over, make sure it works, then remove the original app:

1. Start a new app with the desired name, and copy all code from the original app into that. Make sure you fix the namespaced stuff, in the newly copied code, to match the new app name.

2. makemigrations and migrate

3. Create a data migration that copies the relevant data from the original app's tables into the new app's tables, and migrate again.

At this point, everything still works, because the original app and its data are still in place.

4. Now you can refactor all the dependent code, so it only makes use of the new app. See other answers for examples of what to look out for.

5. Once you are certain that everything works, you can remove the original app.

This has the advantage that every step uses the normal Django migration mechanism, without manual database manipulation, and we can track everything in source control. In addition, we keep the original app and its data in place until we are sure everything works.

Just to show it in a different format that I prefer to use for some reason: The first way returns your itemList as an System.Linq.IOrderedQueryable

using(var context = new ItemEntities())
{
    var itemList = context.Items.Where(x => !x.Items && x.DeliverySelection)
                                .OrderByDescending(x => x.Delivery.SubmissionDate);
}

That approach is fine, but if you wanted it straight into a List Object:

var itemList = context.Items.Where(x => !x.Items && x.DeliverySelection)
                                .OrderByDescending(x => x.Delivery.SubmissionDate).ToList();

All you have to do is append a .ToList() call to the end of the Query.

Something to note, off the top of my head I can't recall if the !(not) expression is acceptable in the Where() call.

You should not start a container just to see the image contents. For instance, you might want to look for malicious content, not run it. Use "create" instead of "run";

docker create --name="tmp_$$" image:tag
docker export tmp_$$ | tar t
docker rm tmp_$$

React events are actually Synthetic Events, not Native Events. As it is written here:

Event delegation: React doesn't actually attach event handlers to the nodes themselves. When React starts up, it starts listening for all events at the top level using a single event listener. When a component is mounted or unmounted, the event handlers are simply added or removed from an internal mapping. When an event occurs, React knows how to dispatch it using this mapping. When there are no event handlers left in the mapping, React's event handlers are simple no-ops.

Try to use Use Event.stopImmediatePropagation:

upvote: (e) ->
  e.stopPropagation();
  e.nativeEvent.stopImmediatePropagation();

Comments have their own line length setting at the bottom of the setting page java->code style->formatter-> Edit... ->comments

If you use Db Browser for sqlite ,then it will be easy for you to modify the table. you can add foreign key in existing table without writing a query.

• Open your database in Db browser,
• Just right click on table and click modify,
• At there scroll to foreign key column,
• double click on field which you want to alter,
• Then select table and it's field and click ok.

that's it. You successfully added foreign key in existing table.

You are not indicating what to include in the archive.

Go one level outside your folder and try:

There is a workaround to guarantee that one handler happens after another: attach the second handler to a containing element and let the event bubble up. In the handler attached to the container, you can look at event.target and do something if it's the one you're interested in.

Crude, maybe, but it definitely should work.

If you click on the empty spot on the report away from any table and then look in properties, one of the Misc fields is called Language which allows you to pick which Language you would like to set, which after doing so can play around with this

Which x can be 1, 2, 3, 4, 5

You can use the document.createElement() function like this:

function addScript( src ) {
  var s = document.createElement( 'script' );
  s.setAttribute( 'src', src );
  document.body.appendChild( s );
}

You can add the following to the <head> of your HTML file:

<script src="https://smtpjs.com/v3/smtp.js"></script>

<script type="text/javascript">
    function sendEmail() {
        Email.send({
            SecureToken: "security token of your smtp",
            To: "[email protected]",
            From: "[email protected]",
            Subject: "Subject...",
            Body: document.getElementById('text').value
        }).then( 
            message => alert("mail sent successfully")
        );
    }
</script>

and below is the HMTL part:

<textarea id="text">write text here...</textarea>
<input type="button" value="Send Email" onclick="sendEmail()">

So the sendEmail() function gets the inputs using:

document.getElementById('id_of_the_element').value

For example, you can add another HTML element such as the subject (with id="subject"):

<textarea id="subject">write text here...</textarea>

and get its value in the sendEmail() function:

Subject: document.getElementById('subject').value

And you are done!

Note: If you do not have a SMTP server you can create one for free here. And then encrypt your SMTP credentials here (the SecureToken attribute in sendEmail() corresponds to the encrypted credentials generated there).

You should only need to unbind the service in onDestroy(). Then, The warning will go.

See here.

As the Activity doc tries to explain, there are three main bind/unbind groupings you will use: onCreate() and onDestroy(), onStart() and onStop(), and onResume() and onPause().

Either make an account on the Nuget.org website, then log in, browse to the package you want and click on the Download link on the left menu.

Or guess the URL. They have the following format:

https://www.nuget.org/api/v2/package/{packageID}/{packageVersion}

Then simply unzip the .nupkg file and extract the contents you need.

While possible, it's potentially very risky - if you attempt to commit changes to the repository from 2 different locations simultaneously, you'll get a giant mess due to the file conflicts. Get a free private SVN host somewhere, or set up a repository on a server you have access to.

Edit based on a recent experience: If you have files open that are managed by Dropbox and your computer crashes, your files may be truncated to 0 bytes. If this happens to the files which manage your repository, your repository will be corrupted. If you discover this soon enough, you can use Dropbox's "recover old version" feature but you're still taking a risk.

The package names in Jackson 2.x got changed to com.fasterxml1 from org.codehaus2. So if you just need ObjectMapper, I think Jackson 1.X can satisfy with your needs.

Here is an example of how to use strtok borrowed from MSDN.

And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

int main( void )
{
    printf( "Tokens:\n" );
    /* Establish string and get the first token: */
    token = strtok( string, seps );
    while( token != NULL )
    {
        /* While there are tokens in "string" */
        printf( " %s\n", token );
        /* Get next token: */
        token = strtok( NULL, seps );
    }
}

JDBC does not support named parameters. Unless you are bound to using plain JDBC (which causes pain, let me tell you that) I would suggest to use Springs Excellent JDBCTemplate which can be used without the whole IoC Container.

NamedParameterJDBCTemplate supports named parameters, you can use them like that:

 NamedParameterJdbcTemplate jdbcTemplate = new NamedParameterJdbcTemplate(dataSource);

 MapSqlParameterSource paramSource = new MapSqlParameterSource();
 paramSource.addValue("name", name);
 paramSource.addValue("city", city);
 jdbcTemplate.queryForRowSet("SELECT * FROM customers WHERE name = :name AND city = :city", paramSource);

I would emphasize the importance of limiting the ::ng-deep to only children of a component by requiring the parent to be an encapsulated css class.

For this to work it's important to use the ::ng-deep after the parent, not before otherwise it would apply to all the classes with the same name the moment the component is loaded.

Using the :host keyword before ::ng-deep will handle this automatically:

:host ::ng-deep .mat-checkbox-layout

Alternatively you can achieve the same behavior by adding a component scoped CSS class before the ::ng-deep keyword:

.my-component ::ng-deep .mat-checkbox-layout {
    background-color: aqua;
}

Component template:

<h1 class="my-component">
    <mat-checkbox ....></mat-checkbox>
</h1>

Resulting (Angular generated) css will then include the uniquely generated name and apply only to its own component instance:

.my-component[_ngcontent-c1] .mat-checkbox-layout {
    background-color: aqua;
}

the way i found was to find the project compiler output (project structure > project). then find the complied folder of the module you wish to turn to a jar, compress it with zip and change the extension of the output from zip to jar.

I found a better way to pass parameters to the popup window and even to retrieve parameters from it :

In the main page :

var popupwindow;
var sharedObject = {};

function openPopupWindow()
{
   // Define the datas you want to pass
   sharedObject.var1 = 
   sharedObject.var2 = 
   ...

   // Open the popup window
   window.open(URL_OF_POPUP_WINDOW, NAME_OF_POPUP_WINDOW, POPUP_WINDOW_STYLE_PROPERTIES);
   if (window.focus) { popupwindow.focus(); }
}

function closePopupWindow()
{
    popupwindow.close();

    // Retrieve the datas from the popup window
    = sharedObject.var1;
    = sharedObject.var2;
    ...
}

In the popup window :

var sharedObject = window.opener.sharedObject;

// function you have to to call to close the popup window
function myclose()
{
    //Define the parameters you want to pass to the main calling window
    sharedObject.var1 = 
    sharedObject.var2 = 
    ...
    window.opener.closePopupWindow();
}

That's it !

And this is very convenient because:

• You have not to set parameters in the URL of the popup window.
• No form to define
• You can use illimited parameters even objects.
• Bi-directionnal : you can pass parameters AND, if you want you, can retreive new parameters.
• Very easy to implement.

Have Fun!

function trimArray(&$value) 
{ 
    $value = trim($value); 
}
$pmcArray = array('php ','mysql ', ' code ');
array_walk($pmcArray, 'trimArray');

by using array_walk function, we can remove space from array elements and elements return the result in same array.

You should create an interface for that like it is working well

public interface Service {
    @FormUrlEncoded
    @POST("v1/EmergencyRequirement.php/?op=addPatient")
    Call<Result> addPerson(@Field("BloodGroup") String bloodgroup,
           @Field("Address") String Address,
           @Field("City") String city, @Field("ContactNumber") String  contactnumber, 
           @Field("PatientName") String name, 
           @Field("Time") String Time, @Field("DonatedBy") String donar);
}

Dumb question/answer perhaps, but have you tried dd/MM/yyyy? Note the capitalization.

mm is for minutes with a leading zero. So I doubt that's what you want.

I've used Spring.NET in the past and had great success with it. I never noticed any substantial overhead with it, though the project we used it on was fairly heavy on its own. It only took a little time reading through the documentation to get it set up.

Active Directory is a super-set of the LDAP protocol. Depending on how the organization uses Active Directory, your LDAP search/set queries may or may not work.

HTTP Is the Protocol handling the transmission of data over the internet.

If that transmission breaks for whatever reason the HTTP error codes tell you why it can't be sent to you.

The data being transmitted is not handled by HTTP Error codes. Only the method of transmission.

HTTP can't say 'Ok, this answer is gobbledigook, but here it is'. it just says 200 OK.

Using Vim, it shouldn't be more involved than hitting Esc, and then typing...

we can find length of array by using array_name.length attribute

int [] i = i.length;

Update : From Angular v1.5, track by $index is now the standard syntax instead of using link as it gave me a ng-repeat dupes error.

I ran into this for a nested ng-repeat and the below worked.

    <td ng-repeat="field in headers track by $index">{{row[field.caption] }}</td>

$("button").click(function() {
    $("#target_div").load("requesting_page_url.html");
});

or

document.getElementById("target_div").innerHTML='<object type="text/html" data="requesting_page_url.html"></object>';

this function worked for me

<?php

{
    $pattern = "#<\s*?$tagname\b[^>]*>(.*?)</$tagname\b[^>]*>#s";
    preg_match($pattern, $string, $matches);

Since Swift 4.2

There is a new set of APIs:

let randomIntFrom0To10 = Int.random(in: 0 ..< 10)
let randomDouble = Double.random(in: 1 ... 10)

• All numeric types now have the random(in:) method that takes range.

• It returns a number uniformly distributed in that range.

TL;DR

Well, what is wrong with the "good" old way?

1. You have to use imported C APIs (They are different between platforms).

2. And moreover...

What if I told you that the random is not that random?

If you use arc4random() (to calculate the remainder) like arc4random() % aNumber, the result is not uniformly distributed between the 0 and aNumber. There is a problem called the Modulo bias.

Modulo bias

Normally, the function generates a random number between 0 and MAX (depends on the type etc.). To make a quick, easy example, let's say the max number is 7 and you care about a random number in the range 0 ..< 2 (or the interval [0, 3) if you prefer that).

The probabilities for individual numbers are:

• 0: 3/8 = 37.5%
• 1: 3/8 = 37.5%
• 2: 2/8 = 25%

In other words, you are more likely to end up with 0 or 1 than 2. Of course, bare in mind that this is extremely simplified and the MAX number is much higher, making it more "fair".

This problem is addressed by SE-0202 - Random unification in Swift 4.2

IE8/9 render the non-breaking hyphen mentioned in CanSpice's answer longer than a typical hyphen. It is the length of an en-dash instead of a typical hyphen. This display difference was a deal breaker for me.

As I could not use the CSS answer specified by Deb I instead opted to use no break tags.

<nobr>e-mail</nobr>

In addition I found a specific scenario that caused IE8/9 to break on a hyphen.

• A string contains words separated by non-breaking spaces -  
• Width is limited
• Contains a dash

IE renders it like this.

The following code reproduces the problem pictured above. I had to use a meta tag to force rendering to IE9 as IE10 has fixed the issue. No fiddle because it does not support meta tags.

<!DOCTYPE html>
<html lang="en">

Define a callback interface to receive whatever parameters you want to pass along in the completion notification. Then invoke it at the end of the task.

You could even write a general wrapper for Runnable tasks, and submit these to ExecutorService. Or, see below for a mechanism built into Java 8.

class CallbackTask implements Runnable {

  private final Runnable task;

  private final Callback callback;

  CallbackTask(Runnable task, Callback callback) {
    this.task = task;
    this.callback = callback;
  }

  public void run() {
    task.run();
    callback.complete();
  }

}

With CompletableFuture, Java 8 included a more elaborate means to compose pipelines where processes can be completed asynchronously and conditionally. Here's a contrived but complete example of notification.

import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ThreadLocalRandom;
import java.util.concurrent.TimeUnit;

public class GetTaskNotificationWithoutBlocking {

  public static void main(String... argv) throws Exception {
    ExampleService svc = new ExampleService();
    GetTaskNotificationWithoutBlocking listener = new GetTaskNotificationWithoutBlocking();
    CompletableFuture<String> f = CompletableFuture.supplyAsync(svc::work);
    f.thenAccept(listener::notify);
    System.out.println("Exiting main()");
  }

  void notify(String msg) {
    System.out.println("Received message: " + msg);
  }

}

class ExampleService {

  String work() {

I guess it would be best to fix the database startup script itself. But as a work around, you can add that line to /etc/rc.local, which is executed about last in init phase.

Try http://www.icescrum.org . It is free to use. And it has lot of cool features. Perfect for scrum teams.

Well, Apache is HTTP webserver, where as Tomcat is also webserver for Servlets and JSP. Moreover Apache is preferred over Apache Tomcat in real time

I had the same problem ( I had to sort my equipments by their name ) and i solved like this:

<% @equipments.sort.each do |name, quantity| %>
...
<% end %>

@equipments is a hash that I build on my model and return on my controller. If you call .sort it will sort the hash based on it's key value.

If you really don't want to run into lots of annoying errors (datediff and such can't be evaluated in DataTable.Select among other things and even if you do as suggested use DataTable.AsEnumerable you will have trouble evaluating DateTime fields) do the following:

1) Model Your Data (create a class with DataTable columns)

Example

public class Person
{
public string PersonId { get; set; }
public DateTime DateBorn { get; set; }
}

2) Add this helper class to your code

public static class Extensions
{
/// <summary>
/// Converts datatable to list<T> dynamically
/// </summary>
/// <typeparam name="T">Class name</typeparam>
/// <param name="dataTable">data table to convert</param>
/// <returns>List<T></returns>
public static List<T> ToList<T>(this DataTable dataTable) where T : new()
{
    var dataList = new List<T>();

    //Define what attributes to be read from the class
    const BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;

    //Read Attribute Names and Types
    var objFieldNames = typeof(T).GetProperties(flags).Cast<PropertyInfo>().
        Select(item => new
        {
            Name = item.Name,
            Type = Nullable.GetUnderlyingType(item.PropertyType) ?? item.PropertyType
        }).ToList();

    //Read Datatable column names and types
    var dtlFieldNames = dataTable.Columns.Cast<DataColumn>().
        Select(item => new {
            Name = item.ColumnName,
            Type = item.DataType
        }).ToList();

    foreach (DataRow dataRow in dataTable.AsEnumerable().ToList())

3) Easily convert your DataTable (dt) to a List of objects with following code:

List<Person> persons = Extensions.ToList<Person>(dt);

4) have fun using Linq without the annoying row.Field<type> bit you have to use when using AsEnumerable

Example

var personsBornOn1980 = persons.Where(x=>x.DateBorn.Year == 1980);

Got this from Bing. Seems Microsoft has removed some features from the core framework and added it to a separate optional(?) framework component.

To quote from MSDN (http://msdn.microsoft.com/en-us/library/cc656912.aspx)

The .NET Framework 4 Client Profile does not include the following features. You must install the .NET Framework 4 to use these features in your application:

* ASP.NET
* Advanced Windows Communication Foundation (WCF) functionality
* .NET Framework Data Provider for Oracle
* MSBuild for compiling

With Spring 4, if your Controller is annotated with @RestController instead of @Controller, you don't need the @ResponseBody annotation.

The code would be

@RestController
public class FooController {

   @RequestMapping(value="/controller", method=GET)
   public String foo() {
      return "Response!";
   }

}

You can find the Javadoc for @RestController here

with many functions in matlab, you don't need to iterate at all.

for example, to multiply by it's position in the list:

m = [1:numel(list)]';
elm = list.*m;

vectorized algorithms in matlab are in general much faster.

You can also use the transform: scale("") option.

Open Your .edmx file in XML editor and then remove tag from Tag and also change store:Schema="dbo" to Schema="dbo" and rebuild the solution now error will resolve and you will be able to save the data.

To obtain multiple outputs from a function and keep them in the desired format you can save the outputs to your hard disk (in the working directory) from within the function and then load them from outside the function:

myfun <- function(x) {
                      df1 <- ...
                      df2 <- ...
                      save(df1, file = "myfile1")
                      save(df2, file = "myfile2")
}
load("myfile1")
load("myfile2")

$('#dropdownid').empty();

That will remove all <option> elements underneath the dropdown element.

If you want to unselect selected items, go with the code from Russ.

Don't try to get them inside its constructor. Try Call them in onDraw() method.

My solution may also be of help to someone.

Tested and Works on IntelliJ 2017.3.2 with Gradle 4.4

Scenario:

I have 2 flavours in my application, and so I wanted each release to be named appropriately according to each flavor.

The code below will be placed into your module gradle build file found in:

{app-root}/app/build.gradle

Gradle code to be added to android{ } block:

android {
    // ...

    defaultConfig {
        versionCode 10
        versionName "1.2.3_build5"
    }

    buildTypes {
        // ...

        release {
            // ...

            applicationVariants.all { 
                variant.outputs.each { output ->
                    output.outputFile = new File(output.outputFile.parent, output.outputFile.name.replace(output.outputFile.name, variant.flavorName + "-" + defaultConfig.versionName + "_v" + defaultConfig.versionCode + ".apk"))
                }
            }

        }
    }

    productFlavors {
        myspicyflavor {
            applicationIdSuffix ".MySpicyFlavor"
            signingConfig signingConfigs.debug
        }

        mystandardflavor {
            applicationIdSuffix ".MyStandardFlavor"
            signingConfig signingConfigs.config
        }
    }
}

The above provides the following APKs found in {app-root}/app/:

myspicyflavor-release-1.2.3_build5_v10.apk
mystandardflavor-release-1.2.3_build5_v10.apk

Hope it can be of use to someone.

Because "not ... =" is two operations and "<>" is only one, it is faster to use "<>".

Here is a quick experiment to prove it:

StartTime = Timer
For x = 1 to 100000000
   If 4 <> 3 Then
   End if
Next
WScript.echo Timer-StartTime

StartTime = Timer
For x = 1 to 100000000
   If Not (4 = 3) Then
   End if
Next
WScript.echo Timer-StartTime

The results I get on my machine:

4.783203
5.552734

For Visual Studio users: Right click on the npm folder and "Restore Packages".

$(document).height() seems to do the trick and gives the total height including the area which is only visible through scrolling.

There's a really good paper by Microsoft Research called To Blob or Not To Blob.

Their conclusion after a large number of performance tests and analysis is this:

• if your pictures or document are typically below 256K in size, storing them in a database VARBINARY column is more efficient

• if your pictures or document are typically over 1 MB in size, storing them in the filesystem is more efficient (and with SQL Server 2008's FILESTREAM attribute, they're still under transactional control and part of the database)

• in between those two, it's a bit of a toss-up depending on your use

If you decide to put your pictures into a SQL Server table, I would strongly recommend using a separate table for storing those pictures - do not store the employee photo in the employee table - keep them in a separate table. That way, the Employee table can stay lean and mean and very efficient, assuming you don't always need to select the employee photo, too, as part of your queries.

For filegroups, check out Files and Filegroup Architecture for an intro. Basically, you would either create your database with a separate filegroup for large data structures right from the beginning, or add an additional filegroup later. Let's call it "LARGE_DATA".

Now, whenever you have a new table to create which needs to store VARCHAR(MAX) or VARBINARY(MAX) columns, you can specify this file group for the large data:

 CREATE TABLE dbo.YourTable
     (....... define the fields here ......)
     ON Data                   -- the basic "Data" filegroup for the regular data
     TEXTIMAGE_ON LARGE_DATA   -- the filegroup for large chunks of data

Check out the MSDN intro on filegroups, and play around with it!

Sometimes this issue is faced when the node server stoped. So, check if your node server working ok.

Then you can use io.set('origins', 'http://yourdomain.com:PORT_NUMBER');

Python functions always return a unique value. The comma operator is the constructor of tuples so self.first_name, self.last_name evaluates to a tuple and that tuple is the actual value the function is returning.

1. Create classes that match your data,
2. then use JSON.NET to convert the JSON data to regular C# objects.

Step 1: a great tool - http://json2csharp.com/ - the results generated by it are below

Step 2: JToken.Parse(...).ToObject<RootObject>().

The 2nd parameter in the get call is a config object. You want something like this:

$http
    .get('accept.php', {
        params: {
            source: link,
            category_id: category
        }
     })
     .success(function (data,status) {
          $scope.info_show = data
     });

See the Arguments section of http://docs.angularjs.org/api/ng.$http for more detail

Set the digits attribute to true, which will cause it to only allow number inputs.

Then do Integer.valueOf(editText.getText()) to get an int value out.

Try using delegate instead of live as here:

$('#link-wrapper').delegate('a', 'click', function() {
  // do something ..
}

For me this perfectly triggers slide event on UI Slider :

hs=$('#height_slider').slider();
hs.slider('option', 'value',h);
hs.slider('option','slide')
       .call(hs,null,{ handle: $('.ui-slider-handle', hs), value: h });

Don't forget to set value by hs.slider('option', 'value',h); before the trigger. Else slider handler will not be in sync with value.

One thing to note here is that h is index/position (not value) in case you are using html select.

Of course Pawel has given the right answer. But I found in this post that since EF 6+ it is possible to save private properties. So I would prefer this code, because you are not able to save the Strings in a wrong way.

public class Test
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    [Column]
    [Required]
    private String StringsAsStrings { get; set; }

    public List<String> Strings
    {
        get { return StringsAsStrings.Split(',').ToList(); }
        set
        {
            StringsAsStrings = String.Join(",", value);
        }
    }
    public Test()
    {
        Strings = new List<string>
        {
            "test",
            "test2",
            "test3",
            "test4"
        };
    }
}

open notepad++, then drag and drop the folder you want to open as tree view.

OR

File ->open folder as workspace , select the file you want.

The maximum row size for an InnoDB table, which applies to data stored locally within a database page, is slightly less than half a page for 4KB, 8KB, 16KB, and 32KB

For 16kb pages (default), we can calculate:

Slightly less than half a page 8126 / Number of bytes to threshold for overflow 767 = 10.59 fields of 767 bytes maximum

Basically, you could max out a row with:

• 11 varchar fields > 767 characters (latin1 = 1 byte per char) or
• 11 varchar fields > 255 characters (utf-8 on mysql = 3 bytes per char).

Remember, it will only overflow to an overflow page if the field is > 767 bytes. If there are too many fields of 767 bytes, it will bust (passing beyond max row_size). Not usual with latin1 but very possible with utf-8 if the developers aren’t careful.

For this case, I think you could possibly bump the innodb_page_size to 32kb.

in my.cnf:

innodb_page_size=32K

Javascript being dynamic language there a zillion ways to mess up where another language would stop you.

Avoiding a fundamental language feature such as new on the basis that you might mess up is a bit like removing your shiny new shoes before walking through a minefield just in case you might get your shoes muddy.

I use a convention where function names begin with a lower case letter and 'functions' that are actually class definitions begin with a upper case letter. The result is a really quite compelling visual clue that the 'syntax' is wrong:-

var o = MyClass();  // this is clearly wrong.

On top of this good naming habits help. After all functions do things and therefore there should be a verb in its name whereas classes represent objects and are nouns and adjectives with no verb.

var o = chair() // Executing chair is daft.
var o = createChair() // makes sense.

Its interesting how SO's syntax colouring has interpretted the code above.

You have to implement KeyListener,take a look here: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

I performed tests on Eclipse vs Netbeans 8.0.2, both with Java version 1.8; I used System.nanoTime() for measurements.

Eclipse:

I got the same time on both cases - around 1.564 seconds.

Netbeans:

• Using "#": 1.536 seconds
• Using "B": 44.164 seconds

So, it looks like Netbeans has bad performance on print to console.

After more research I realized that the problem is line-wrapping of the max buffer of Netbeans (it's not restricted to System.out.println command), demonstrated by this code:

for (int i = 0; i < 1000; i++) {
    long t1 = System.nanoTime();
    System.out.print("BBB......BBB"); \\<-contain 1000 "B"
    long t2 = System.nanoTime();
    System.out.println(t2-t1);
    System.out.println("");
}

The time results are less then 1 millisecond every iteration except every fifth iteration, when the time result is around 225 millisecond. Something like (in nanoseconds):

BBB...31744
BBB...31744
BBB...31744
BBB...31744
BBB...226365807
BBB...31744
BBB...31744
BBB...31744
BBB...31744
BBB...226365807
.
.
.

And so on..

Summary:

1. Eclipse works perfectly with "B"
2. Netbeans has a line-wrapping problem that can be solved (because the problem does not occur in eclipse)(without adding space after B ("B ")).

Try this:

panel1.BackColor = Color.FromArgb(100, 88, 44, 55);

change alpha(A) to get desired opacity.

I've created a tool to SSH and CD into a server consecutively – aptly named sshcd. For the example you've given, you'd simply use:

sshcd somehost:/some/directory/somewhere/named/Foo

Let me know if you have any questions or problems!

Normal ways would be Integer.toString(i) or String.valueOf(i).

The concatenation will work, but it is unconventional and could be a bad smell as it suggests the author doesn't know about the two methods above (what else might they not know?).

Java has special support for the + operator when used with strings (see the documentation) which translates the code you posted into:

StringBuilder sb = new StringBuilder();
sb.append("");
sb.append(i);
String strI = sb.toString();

at compile-time. It's slightly less efficient (sb.append() ends up calling Integer.getChars(), which is what Integer.toString() would've done anyway), but it works.

   1:    istore_1

Initialise the StringBuilder:

   2:    new    #2; //class java/lang/StringBuilder
   5:    dup
   6:    invokespecial    #3; //Method java/lang/StringBuilder."<init>":()V

Append the empty string:

   9:    ldc    #4; //String
   11:    invokevirtual    #5; //Method java/lang/StringBuilder.append:
(Ljava/lang/String;)Ljava/lang/StringBuilder;

Append the integer:

   14:    iload_1
   15:    invokevirtual    #6; //Method java/lang/StringBuilder.append:
(I)Ljava/lang/StringBuilder;

Extract the final string:

   18:    invokevirtual    #7; //Method java/lang/StringBuilder.toString:
()Ljava/lang/String;
   21:    astore_2
   22:    return
}

There's a proposal and ongoing work to change this behaviour, targetted for JDK 9.

there's no timeout support in the fetch API yet. But it could be achieved by wrapping it in a promise.

for eg.

  function fetchWrapper(url, options, timeout) {
    return new Promise((resolve, reject) => {
      fetch(url, options).then(resolve, reject);

      if (timeout) {
        const e = new Error("Connection timed out");
        setTimeout(reject, timeout, e);
      }
    });
  }

You can use dijkstra's algorithm with negative edges not including negative cycle, but you must allow a vertex can be visited multiple times and that version will lose it's fast time complexity.

In that case practically I've seen it's better to use SPFA algorithm which have normal queue and can handle negative edges.

So..it was SSL problem. Whatever I was doing was absolutely correct. Only that I was not using the ssl option. So I added "-Usessl true" to my original command and it worked.

I think you had the correct idea with your last example. You only got an error because you were trying to put quotes inside an already quoted string. This will fix it:

gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output ($_.GetValue("DisplayName") + "`n") }

Edit: Keith's $() operator actually creates a better syntax (I always forget about this one). You can also escape quotes inside quotes as so:

gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output "$($_.GetValue(`"DisplayName`"))`n" }

Try this JS solution that toggles webkitOverflowScrolling style. The trick here is that this style is off, mobile Safari goes to ordinary scrolling and prevents over-bounce — alas, it is not able to cancel ongoing drag. This complex solution also tracks onscroll as bounce over the top makes scrollTop negative that may be tracked. This solution was tested on iOS 12.1.1 and has single drawback: while accelerating the scroll single over-bounce still happens as resetting the style may not cancel it immediately.

function preventScrollVerticalBounceEffect(container) {
  setTouchScroll(true) //!: enable before the first scroll attempt

  container.addEventListener("touchstart", onTouchStart)
  container.addEventListener("touchmove", onTouch, { passive: false })
  container.addEventListener("touchend", onTouchEnd)
  container.addEventListener("scroll", onScroll)

  function isTouchScroll() {
    return !!container.style.webkitOverflowScrolling
  }

  let prevScrollTop = 0, prevTouchY, opid = 0

  function setTouchScroll(on) {
    container.style.webkitOverflowScrolling = on ? "touch" : null

    //Hint: auto-enabling after a small pause makes the start
    // smoothly accelerated as required. After the pause the
    // scroll position is settled, and there is no delta to
    // make over-bounce by dragging the finger. But still,
    // accelerated content makes short single over-bounce
    // as acceleration may not be off instantly.

    const xopid = ++opid
    !on && setTimeout(() => (xopid === opid) && setTouchScroll(true), 250)

    if(!on && container.scrollTop < 16)
      container.scrollTop = 0
    prevScrollTop = container.scrollTop
  }

  function isBounceOverTop() {
    const dY = container.scrollTop - prevScrollTop
    return dY < 0 && container.scrollTop < 16
  }

  function isBounceOverBottom(touchY) {
    const dY = touchY - prevTouchY

    //Hint: trying to bounce over the bottom, the finger moves
    // up the screen, thus Y becomes smaller. We prevent this.

    return dY < 0 && container.scrollHeight - 16 <=
      container.scrollTop + container.offsetHeight
  }

  function onTouchStart(e) {
    prevTouchY = e.touches[0].pageY
  }

  function onTouch(e) {
    const touchY = e.touches[0].pageY

    if(isBounceOverBottom(touchY)) {
      if(isTouchScroll())
        setTouchScroll(false)
      e.preventDefault()
    }

    prevTouchY = touchY
  }

  function onTouchEnd() {
    prevTouchY = undefined
  }

  function onScroll() {
    if(isTouchScroll() && isBounceOverTop()) {
      setTouchScroll(false)
    }
  }
}

Maybe this code helps:

var chunk_size = 10;_x000D_
var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17];_x000D_
var groups = arr.map( function(e,i){ _x000D_
     return i%chunk_size===0 ? arr.slice(i,i+chunk_size) : null; _x000D_
}).filter(function(e){ return e; });_x000D_
console.log({arr, groups})

You can use a lightweight library pure-md5. Just a 4.7kb.

$("#file-dialog").change(function() {_x000D_
  handleFiles(this.files);_x000D_
});_x000D_
_x000D_
function handleFiles(files) {_x000D_
  for (var index = 0; index < files.length; index++) {_x000D_
    var file = files[index];_x000D_
    var fileReader = new FileReader();_x000D_
    fileReader.onload = function(e) {_x000D_
      $('body').append(`_x000D_
        <div style="margin-top: 2rem;">_x000D_
          <span>${file.name}: </span>_x000D_
          <span>${(md5(e.target.result))}</span>_x000D_
        </div>_x000D_
      `);_x000D_
    }_x000D_
_x000D_
    fileReader.readAsText(file, 'utf-8');_x000D_
  }_x000D_
_x000D_
}

body {_x000D_
  font-family: sans-serif;_x000D_
}

<script src="https://unpkg.com/[email protected]/lib/index.js"></script>_x000D_

<input type="file" id="file-dialog" multiple="true" accept="image/*">

Well, for a link, there must be a link tag around. what you can also do is that make a css class for the button and assign that class to the link tag. like,

#btn {_x000D_
  background: url(https://image.flaticon.com/icons/png/128/149/149668.png) no-repeat 0 0;_x000D_
  display: block;_x000D_
  width: 128px;_x000D_
  height: 128px;_x000D_
  border: none;_x000D_
  outline: none;_x000D_
}

<a href="btnlink.html" id="btn"></a>

add this to your form:

<form  id="regform" action="insert.php" method="post">

add this to your function:

<script>
    function myFunction() {
        var pass1 = document.getElementById("pass1").value;
        var pass2 = document.getElementById("pass2").value;
        if (pass1 != pass2) {
            //alert("Passwords Do not match");
            document.getElementById("pass1").style.borderColor = "#E34234";
            document.getElementById("pass2").style.borderColor = "#E34234";
        }
        else {
            alert("Passwords Match!!!");
            document.getElementById("regForm").submit();
        }
    }
</script>

This works:

$category = $catrep->createQueryBuilder('cc')
        ->select('cc.categoryid')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->distinct()
        ->getQuery();

$categories = $category->getResult();

Edit for Symfony 3 & 4.

You should use ->groupBy('cc.categoryid') instead of ->distinct()

Based on mathematical concepts, I understand that:

• all natural numbers that, divided by n, having 0 as remainder, are all multiples of n

Therefore, the following calculation also applies as a solution (multiples between 1 and 100):

>>> multiples_5 = [n for n in range(1, 101) if n % 5 == 0]
>>> multiples_5
[5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100]

Node.js has included experimental support for ES6 support. Read more about here: https://nodejs.org/docs/latest-v13.x/api/esm.html#esm_enabling.

TLDR;

Node.js >= v13

It's very simple in Node.js 13 and above. You need to either:

• Save the file with .mjs extension, or
• Add { "type": "module" } in the nearest package.json.

You only need to do one of the above to be able to use ECMAScript modules.

Node.js <= v12

If you are using Node.js version 8-12, save the file with ES6 modules with .mjs extension and run it like:

node --experimental-modules my-app.mjs

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <scope>runtime</scope>

Try this.

public function getDownload()
{
    //PDF file is stored under project/public/download/info.pdf
    $file= public_path(). "/download/info.pdf";

    $headers = array(
              'Content-Type: application/pdf',
            );

    return Response::download($file, 'filename.pdf', $headers);
}

"./download/info.pdf"will not work as you have to give full physical path.

Update 20/05/2016

Laravel 5, 5.1, 5.2 or 5.* users can use the following method instead of Response facade. However, my previous answer will work for both Laravel 4 or 5. (the $header array structure change to associative array =>- the colon after 'Content-Type' was deleted - if we don't do those changes then headers will be added in wrong way: the name of header wil be number started from 0,1,...)

$headers = [
              'Content-Type' => 'application/pdf',
           ];

return response()->download($file, 'filename.pdf', $headers);

Kotlin:

val selectedIndex = radioButtonGroup?.indexOfChild(
  radioButtonGroup?.findViewById(
    radioButtonGroup.getCheckedRadioButtonId())
)

Here is what I found out to achieve a similar problem with my data set.

First, do what James mentioned above, i.e.

test[ , order(names(test))]

Second, use the everything() function in dplyr to move specific columns of interest (e.g., "D", "G", "K") at the beginning of the data frame, putting the alphabetically ordered columns after those ones.

select(test, D, G, K, everything())

Use Java's replaceAll(String regex, String replacement)

For example, Use a substitution char for the quotes and then replace that char with \"

String newstring = String.replaceAll("%","\"");

or replace all instances of \" with \\\"

String newstring = String.replaceAll("\"","\\\"");

Another way to get the EF version you are using is to open the Package Manager Console (PMC) in Visual Studio and type Get-Package at the prompt. The first line with be for EntityFramework and list the version the project has installed.

With the integration of JEP 325: Switch Expressions (Preview) in JDK-12 early access builds, one can now make use of the new form of the switch label as :-

case text1, text4 -> {
     //blah
} 

or to rephrase the demo from one of the answers, something like :-

public class RephraseDemo {

    public static void main(String[] args) {
        int month = 9;
        int year = 2018;
        int numDays = 0;

        switch (month) {
            case 1, 3, 5, 7, 8, 10, 12 ->{
                numDays = 31;
            }
            case 4, 6, 9, 11 ->{
                numDays = 30;
            }
            case 2 ->{
                if (((year % 4 == 0) &&
                        !(year % 100 == 0))
                        || (year % 400 == 0))
                    numDays = 29;
                else
                    numDays = 28;
            }
            default ->{
                System.out.println("Invalid month.");

            }
        }
        System.out.println("Number of Days = " + numDays);
    }
}

Here is how you can give it a try - Compile a JDK12 preview feature with Maven

You can also try using String Tokeniser, for any space, tab, newline, and all. A simple way is,

String s = "Your Text Here";        
StringTokenizer st = new StringTokenizer( s, " " );
while(st.hasMoreTokens())
{
    System.out.print(st.nextToken());
}

Gulp 4.0 has changed the way that tasks should be defined if the task depends on another task to execute. The list parameter has been deprecated.

An example from your gulpfile.js would be:

// Starts a BrowerSync instance
gulp.task('server', ['build'], function(){
  browser.init({server: './_site', port: port});
});

Instead of the list parameter they have introduced gulp.series() and gulp.parallel().

This task should be changed to something like this:

// Starts a BrowerSync instance
gulp.task('server', gulp.series('build', function(){
  browser.init({server: './_site', port: port});
}));

I'm not an expert in this. You can see a more robust example in the gulp documentation for running tasks in series or these following excellent blog posts by Jhey Thompkins and Stefan Baumgartner

https://codeburst.io/switching-to-gulp-4-0-271ae63530c0

If element is not clickable and overlay issue is ocuring we use arguments[0].click().

WebElement ele = driver.findElement(By.xpath("//div[@class='input-group-btn']/input")); JavascriptExecutor executor = (JavascriptExecutor)driver; executor.executeScript("arguments[0].click();", ele);

Lots of options here.

For a pure JS solution, have your page submit to itself, but with additional URL parameter (mypage.html?postback=true) - you can then get the page url with window.location.href, and parse that using a split or regex to look for your variable.

The much easier one, assuming you sending back to some sort of scripting language to proces the page (php/perl/asp/cf et. al), is to have them echo a line of javascript in the page setting a variable:

<html>

<?php
if ($_POST['myVar']) {
    //postback
    echo '<script>var postingBack = true;</script>';
    //Do other processing
} else {
    echo '<script>var postingBack = false;</script>'
 } ?>
<script>
function myLoader() {
     if (postingBack == false) {
          //Do stuff
     }
 }

<body onLoad="myLoader():"> ...

You can use the CSS property page-break-before (or page-break-after). Just set page-break-before: always on those block-level elements (e.g., heading, div, p, or table elements) that should start on a new line.

For example, to cause a line break before any 2nd level heading and before any element in class newpage (e.g., <div class=newpage>...), you would use

h2, .newpage { page-break-before: always }

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /Foldername of your ci/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

I can think of a cheeky way to do it, I don't think this will be the best option but it will work.

Create the header as a separate table then place the other in a div and set a max size, then allow the scroll to come in by using overflow.

table {_x000D_
  width: 500px;_x000D_
}_x000D_
_x000D_
.scroll {_x000D_
  max-height: 60px;_x000D_
  overflow: auto;_x000D_
}

<table border="1">_x000D_
  <tr>_x000D_
  <th>head1</th>_x000D_
  <th>head2</th>_x000D_
  <th>head3</th>_x000D_
  <th>head4</th>_x000D_
  </tr>_x000D_
</table>_x000D_
<div class="scroll">_x000D_
  <table>_x000D_

wait until this call is finish its executing

You will need to call AsyncTask.get() method for getting result back and make wait until doInBackground execution is not complete. but this will freeze Main UI thread if you not call get method inside a Thread.

To get result back in UI Thread start AsyncTask as :

String str_result= new RunInBackGround().execute().get();

Please bear in mind that some .NET controls will automatically HTML encode the output. For instance, setting the .Text property on a TextBox control will automatically encode it. That specifically means converting < into <, > into > and & into &. So be wary of doing this...

myTextBox.Text = Server.HtmlEncode(myStringFromDatabase); // Pseudo code

However, the .Text property for HyperLink, Literal and Label won't HTML encode things, so wrapping Server.HtmlEncode(); around anything being set on these properties is a must if you want to prevent <script> window.location = "http://www.google.com"; </script> from being output into your page and subsequently executed.

Do a little experimenting to see what gets encoded and what doesn't.

in c# this is working :D

protect void button1_Click(object sender, EventArgs e){
    button2_Click(button2, null);
}

protect void button2_Click(object sender, EventeArgs e){
    //some codes here
}

for vb.net

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)   Handles Button1.Click
    Button2_Click(Sender, e)
End Sub

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)   Handles Button2.Click
    //some codes here
End Sub

A solution with service and awk that takes in a comma-delimited list of service names.

First it's probably a good bet you'll need root privileges to do what you want. If you don't need to check then you can remove that part.

#!/usr/bin/env bash

# First parameter is a comma-delimited string of service names i.e. service1,service2,service3
SERVICES=$1

ALL_SERVICES_STARTED=true

if [ $EUID -ne 0 ]; then
  if [ "$(id -u)" != "0" ]; then
    echo "root privileges are required" 1>&2
    exit 1
  fi
  exit 1
fi

for service in ${SERVICES//,/ }
do
    STATUS=$(service ${service} status | awk '{print $2}')

    if [ "${STATUS}" != "started" ]; then
        echo "${service} not started"
        ALL_SERVICES_STARTED=false
    fi
done

if ${ALL_SERVICES_STARTED} ; then
    echo "All services started"
    exit 0
else
    echo "Check Failed"
    exit 1
fi

If you need to wrap a private method inside a transaction and don't want to use aspectj, you can use TransactionTemplate.

@Service
public class MyService {

    @Autowired
    private TransactionTemplate transactionTemplate;

    private void process(){
        transactionTemplate.execute(new TransactionCallbackWithoutResult() {
            @Override
            protected void doInTransactionWithoutResult(TransactionStatus status) {
                processInTransaction();
            }
        });

    }

    private void processInTransaction(){
        //...
    }

}

Using reduce() from purrr is slightly faster than rowSums and definately faster than apply, since you avoid iterating over all the rows and just take advantage of the vectorized operations:

library(purrr)
library(dplyr)
iris %>% mutate(Petal = reduce(select(., starts_with("Petal")), `+`))

emacs works very well with files into the 100's of megabytes, I've used it on log files without too much trouble.

But generally when I have some kind of analysis task, I find writing a perl script a better choice.

Connect your javascript clientside controller and php serverside controller using sending and receiving opcodes with binded data. So your php code can send as response functional delta for js recepient/listener

You want in page A to know the URL of page B?

Or to know in page B the URL of page A?

In Page B: document.referrer if set. As already shown here: How to get the previous URL in JavaScript?

In page A you would need to read a cookie or local/sessionStorage you set in page B, assuming the same domains

You should put this line in your application context:

Check if you're referencing jquery.js BEFORE bootstrap.js and bootstrap.js is loaded only once. That fixed the same error for me:

<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>

... and the uppercase is:

"Awesome String".upcase
=> "AWESOME STRING"

Here is a simple way. Reflector is not needed.

    public static string GetQueryStringWithOutParameter(string parameter)
    {
        var nameValueCollection = System.Web.HttpUtility.ParseQueryString(HttpContext.Current.Request.QueryString.ToString());
        nameValueCollection.Remove(parameter);
        string url = HttpContext.Current.Request.Path + "?" + nameValueCollection;

        return url;
    }

Here QueryString.ToString() is required because Request.QueryString collection is read only.

The MD5 Hash algorithm is not reversible, so MD5 decode in not possible, but some website have bulk set of password match, so you can try online for decode MD5 hash.

Try online :

MD5 Decrypt

md5online

md5decrypter

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

Update 2019 - Bootstrap 4

"Centered content" can mean many different things, and Bootstrap centering has changed a lot since the original post.

Horizontal Center

Bootstrap 3

• text-center is used for display:inline elements
• center-block to center display:block elements
• col-*offset-* to center grid columns
• see this answer to center the navbar

Demo Bootstrap 3 Horizontal Centering

Bootstrap 4

• text-center is still used for display:inline elements
• mx-auto replaces center-block to center display:block elements
• offset-* or mx-auto can be used to center grid columns
• justify-content-center in row can also be used to center col-*

mx-auto (auto x-axis margins) will center display:block or display:flex elements that have a defined width, (%, vw, px, etc..). Flexbox is used by default on grid columns, so there are also various flexbox centering methods.

Demo Bootstrap 4 Horizontal Centering

Vertical Center

Now that Bootstrap 4 is flexbox by default there are many different approaches to vertical alignment using: auto-margins, flexbox utils, or the display utils along with vertical align utils. At first "vertical align utils" seems obvious but these only work with inline and table display elements. Here are some Bootstrap 4 vertical centering options..

1 - Vertical Center Using Auto Margins:

Another way to vertically center is to use my-auto. This will center the element within it's container. For example, h-100 makes the row full height, and my-auto will vertically center the col-sm-12 column.

<div class="row h-100">
    <div class="col-sm-12 my-auto">
        <div class="card card-block w-25">Card</div>
    </div>
</div>

Vertical Center Using Auto Margins Demo

my-auto represents margins on the vertical y-axis and is equivalent to:

margin-top: auto;
margin-bottom: auto;

2 - Vertical Center with Flexbox:

Since Bootstrap 4 .row is now display:flex you can simply use align-self-center on any column to vertically center it...

       <div class="row">
           <div class="col-6 align-self-center">
                <div class="card card-block">
                 Center
                </div>
           </div>
           <div class="col-6">
                <div class="card card-inverse card-danger">
                    Taller
                </div>
          </div>
    </div>

or, use align-items-center on the entire .row to vertically center align all col-* in the row...

       <div class="row align-items-center">
           <div class="col-6">
                <div class="card card-block">
                 Center
                </div>
           </div>
           <div class="col-6">
                <div class="card card-inverse card-danger">
                    Taller
                </div>
          </div>
    </div>

Vertical Center Different Height Columns Demo

3 - Vertical Center Using Display Utils:

Bootstrap 4 has display utils that can be used for display:table, display:table-cell, display:inline, etc.. These can be used with the vertical alignment utils to align inline, inline-block or table cell elements.

<div class="row h-50">
    <div class="col-sm-12 h-100 d-table">
        <div class="card card-block d-table-cell align-middle">
            I am centered vertically
        </div>
    </div>
</div>

Scalar Function cause all sorts of performance issues, so its better to wrap the logic into an Inline Table Valued Function if possible. This is the function I used to replace some User Defined Functions which selected the Min/Max dates from a list of upto ten dates. When tested on my dataset of 1 Million rows the Scalar Function took over 15 minutes before I killed the query the Inline TVF took 1 minute which is the same amount of time as selecting the resultset into a temporary table. To use this call the function from either a subquery in the the SELECT or a CROSS APPLY.

CREATE FUNCTION dbo.Get_Min_Max_Date
(
    @Date1  datetime,
    @Date2  datetime,
    @Date3  datetime,
    @Date4  datetime,
    @Date5  datetime,
    @Date6  datetime,
    @Date7  datetime,
    @Date8  datetime,
    @Date9  datetime,
    @Date10 datetime
)
RETURNS TABLE
AS
RETURN
(
    SELECT      Max(DateValue)  Max_Date,
                Min(DateValue)  Min_Date
    FROM        (
                    VALUES  (@Date1),
                            (@Date2),
                            (@Date3),
                            (@Date4),
                            (@Date5),
                            (@Date6),
                            (@Date7),
                            (@Date8),
                            (@Date9),
                            (@Date10)
                )   AS Dates(DateValue)
)

you can try like that. try: self.assertRaises(None,function,arg1, arg2) except: pass if you don't put code inside try block it will through exception' AssertionError: None not raised " and test case will be failed. Test case will be pass if put inside try block which is expected behaviour.

I had researched this and the URLRewrite method works well. Can't seem to find the change scripted anywhere well. I wrote this compatible with PowerShell v2 and above and tested it on IIS 7.5.

# Add Allowed Server Variable
    Add-WebConfiguration /system.webServer/rewrite/allowedServerVariables -atIndex 0 -value @{name="RESPONSE_SERVER"}
# Rule Name
    $ruleName = "Remove Server Response Header"
# Add outbound IIS Rewrite Rule
    Add-WebConfigurationProperty -pspath "iis:\" -filter "system.webServer/rewrite/outboundrules" -name "." -value @{name=$ruleName; stopProcessing='False'}
#Set Properties of newly created outbound rule 
    Set-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST"  -filter "system.webServer/rewrite/outboundRules/rule[@name='$ruleName']/match" -name "serverVariable" -value "RESPONSE_SERVER"
    Set-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST"  -filter "system.webServer/rewrite/outboundRules/rule[@name='$ruleName']/match" -name "pattern" -value ".*"
    Set-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST"  -filter "system.webServer/rewrite/outboundRules/rule[@name='$ruleName']/action" -name "type" -value "Rewrite"

I use this simple one: https://www.npmjs.com/package/csv-parser

Very simple to use:

const csv = require('csv-parser')
const fs = require('fs')
const results = [];

fs.createReadStream('./CSVs/Update 20191103C.csv')
  .pipe(csv())
  .on('data', (data) => results.push(data))
  .on('end', () => {
    console.log(results);
    console.log(results[0]['Lowest Selling Price'])
  });

Increasing SQL-Wait-Timeout worked for me in this case, try this:

mysql_query("SET @@session.wait_timeout=900", $link);

before you first "normal" SQL queries.

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

!=

For example,

if ("apple" != "orange")
  // true, the string "apple" is not equal to the string "orange"

Means not. See also the logical operators list. Also, when you see triple characters, it's a type sensitive comparison. (e.g. if (1 === '1') [not equal])

I recommend using DateTime objects instead of strings, because you cannot easily compare strings, which is required for sorting. You also get additional advantages for working with dates.

Once you have the DateTime objects, sorting is quite easy:

usort($array, function($a, $b) {
  return ($a['date'] < $b['date']) ? -1 : 1;
});
