On my JDK (Windows 10 64 bit, 1.8.0_65-b17) I can reproduce and explain:

public static void main(String[] args) {
    int repeat = 10;
    long A = 0;
    long B = 0;
    for (int i = 0; i < repeat; i++) {
        A += test();
        B += testB();
    }

    System.out.println(A / repeat + " ms");
    System.out.println(B / repeat + " ms");
}


private static long test() {
    int n = 0;
    for (int i = 0; i < 1000; i++) {
        n += multi(i);
    }
    long startTime = System.currentTimeMillis();
    for (int i = 0; i < 1000000000; i++) {
        n += multi(i);
    }
    long ms = (System.currentTimeMillis() - startTime);
    System.out.println(ms + " ms A " + n);
    return ms;
}


private static long testB() {
    int n = 0;
    for (int i = 0; i < 1000; i++) {
        n += multiB(i);
    }
    long startTime = System.currentTimeMillis();
    for (int i = 0; i < 1000000000; i++) {
        n += multiB(i);
    }
    long ms = (System.currentTimeMillis() - startTime);
    System.out.println(ms + " ms B " + n);
    return ms;
}

private static int multiB(int i) {
    return 2 * (i * i);
}

private static int multi(int i) {
    return 2 * i * i;
}

Output:

...
405 ms A 785527736
327 ms B 785527736
404 ms A 785527736
329 ms B 785527736
404 ms A 785527736
328 ms B 785527736
404 ms A 785527736
328 ms B 785527736
410 ms
333 ms

So why? The byte code is this:

 private static multiB(int arg0) { // 2 * (i * i)
     <localVar:index=0, name=i , desc=I, sig=null, start=L1, end=L2>

     L1 {
         iconst_2
         iload0
         iload0
         imul
         imul
         ireturn
     }
     L2 {
     }
 }

 private static multi(int arg0) { // 2 * i * i
     <localVar:index=0, name=i , desc=I, sig=null, start=L1, end=L2>

     L1 {
         iconst_2
         iload0
         imul
         iload0
         imul
         ireturn
     }
     L2 {
     }
 }

The difference being: With brackets (2 * (i * i)):

• push const stack
• push local on stack
• push local on stack
• multiply top of stack
• multiply top of stack

Without brackets (2 * i * i):

• push const stack
• push local on stack
• multiply top of stack
• push local on stack
• multiply top of stack

Loading all on the stack and then working back down is faster than switching between putting on the stack and operating on it.

You can use this code :

.row :nth-child(odd){
  background-color:red;
}
.row :nth-child(even){
  background-color:green;
}

Just summarising @libing's answer with a sample that worked for me.

val gson = Gson()
val todoItem: TodoItem = gson.fromJson(this.assets.readAssetsFile("versus.json"), TodoItem::class.java)

private fun AssetManager.readAssetsFile(fileName : String): String = open(fileName).bufferedReader().use{it.readText()}

Without this extension function the same can be achieved by using BufferedReader and InputStreamReader this way:

val i: InputStream = this.assets.open("versus.json")
val br = BufferedReader(InputStreamReader(i))
val todoItem: TodoItem = gson.fromJson(br, TodoItem::class.java)

you are thinking too much... Take a look at this [i think this is what you wanted - if not let me know]

http://www.bootply.com/118886

css

.even{background: red; color:white;}
.odd{background: darkred; color:white;}

html

<div class="container">
  <ul class="list-unstyled">
    <li class="col-md-6 odd">Dumby Content</li>
    <li class="col-md-6 odd">Dumby Content</li>
    <li class="col-md-6 even">Dumby Content</li>
    <li class="col-md-6 even">Dumby Content</li>
    <li class="col-md-6 odd">Dumby Content</li>
    <li class="col-md-6 odd">Dumby Content</li>
  </ul>
</div>

Unfortunately, you can't change the font size or styling in a drop-down list that is created using data validation.

You can style the text in a combo box, however. Follow the instructions here: Excel Data Validation Combo Box

The container class is intentionally not 100% width. It is different fixed widths depending on the width of the viewport.

If you want to work with the full width of the screen, use .container-fluid:

Bootstrap 3:

<body>
  <div class="container-fluid">
    <div class="row">
      <div class="col-lg-6"></div>
      <div class="col-lg-6"></div>
    </div>
    <div class="row">
      <div class="col-lg-8"></div>
      <div class="col-lg-4"></div>
    </div>

For Xamarin Android align to the left of an object

int dp24 = (int)TypedValue.ApplyDimension( ComplexUnitType.Dip, 24, Resources.System.DisplayMetrics );
            RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( dp24, dp24 );
            lp.AddRule( LayoutRules.CenterInParent, 1 );
            lp.AddRule( LayoutRules.LeftOf, //Id of the field Eg m_Button.Id ); 
            m_Button.LayoutParameters = lp;

I've created a library with a custom view to solve this issue, and it should be very simple to use. See https://github.com/Comcast/DahDit for more. You can add dashed lines like this:

<com.xfinity.dahdit.DashedLine
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    app:dashHeight="4dp"
    app:dashLength="8dp"
    app:minimumDashGap="3dp"
    app:layout_constraintRight_toRightOf="parent"
    android:id="@+id/horizontal_dashes"/>

Add HeaderStyle-Width and ItemStyle-width to TemplateFiels

tr.rowhighlight td, tr.rowhighlight th{
    background-color:#f0f8ff;
}

I recommend this approach:

Instead of having two click handlers, have only one function with a if-else statement. Let the state of the BUTTON element determine which branch of the if-else statement gets executed:

HTML:

<button id="a" onclick="toggleError(this)">Button A</button>

JavaScript:

function toggleError(button) { 
    if ( button.className === 'visible' ) {
        // HIDE ERROR
        button.className = '';
    } else {
        // SHOW ERROR
        button.className = 'visible';
    }
}

Live demo: http://jsfiddle.net/simevidas/hPQP9/

The :nth-child(n) selector matches every element that is the nth child, regardless of type, of its parent. Odd and even are keywords that can be used to match child elements whose index is odd or even (the index of the first child is 1).

this is what you want:

<html>
    <head>
        <style>
            li { color: blue }<br>
            li:nth-child(even) { color:red }
            li:nth-child(odd) { color:green}
        </style>
    </head>
    <body>
        <ul>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
        </ul>
    </body>
</html>

Got it! I found an idea here

http://www.mail-archive.com/[email protected]/msg18410.html

In this example, they loaded a blank popup window into an object, cloned the contents of the element to be displayed, and appended it to the body of the object. Since I already knew what the contents of view-details (or any page I load in the lightbox), I just had to clone that content instead and load it into an object. Then, I just needed to print that object. The final outcome looks like this:

$('.printBtn').bind('click',function() {
    var thePopup = window.open( '', "Customer Listing", "menubar=0,location=0,height=700,width=700" );
    $('#popup-content').clone().appendTo( thePopup.document.body );
    thePopup.print();
});

I had one small drawback in that the style sheet I was using in view-details.php was using a relative link. I had to change it to an absolute link. The reason being that the window didn't have a URL associated with it, so it had no relative position to draw on.

Works in Firefox. I need to test it in some other major browsers too.

I don't know how well this solution works when you're dealing with images, videos, or other process intensive solutions. Although, it works pretty well in my case, since I'm just loading tables and text values.

Thanks for the input! You gave me some ideas of how to get around this.

You may also want to add

table td { border:0; }

the above is equivalent to setting cellpadding="0"

it gets rid of the padding automatically added to cells by browsers which may depend on doctype and/or any CSS used to reset default browser styles

For me, this works:

function transferAllStyles(elemFrom, elemTo)
{
  var prop;
  for (prop in elemFrom.style)
    if (typeof prop == "string")
      try { elemTo.style[prop] = elemFrom.style[prop]; }
      catch (ex) { /* don't care */ }
}

for group headers/footers:

=iif(RunningValue(*group on field*,CountDistinct,"*parent group name*") Mod 2,"White","AliceBlue")

You can also use this to “reset” the row color count within each group. I wanted the first detail row in each sub group to start with White and this solution (when used on the detail row) allowed that to happen:

=IIF(RunningValue(Fields![Name].Value, CountDistinct, "NameOfPartnetGroup") Mod 2, "White", "Wheat")

See: http://msdn.microsoft.com/en-us/library/ms159136(v=sql.100).aspx

if you are in a activity, assume there is only one root view,you can get it like this.

ViewGroup viewGroup = (ViewGroup) ((ViewGroup) this
        .findViewById(android.R.id.content)).getChildAt(0);

you can then cast it to your real class

or you could using

getWindow().getDecorView();

notice this will include the actionbar view, your view is below the actionbar view

Try this using apache commons:

String src = "Hello"; //This will work with any serialisable object
System.out.println(
            "Object Size:" + SerializationUtils.serialize((Serializable) src).length)

Basically, since Python 3.x you need to use print with parenthesis.

Python 2.x: print "Lord of the Rings"

Python 3.x: print("Lord of the Rings")

Explaination

print was a statement in 2.x, but it's a function in 3.x. Now, there are a number of good reasons for this.

1. With function format of Python 3.x, more flexibility comes when printing multiple items with comman separated.
2. You can't use argument splatting with a statement. In 3.x if you have a list of items that you want to print with a separator, you can do this:

>>> items = ['foo', 'bar', 'baz']
>>> print(*items, sep='+') 
foo+bar+baz

3. You can't override a statement. If you want to change the behavior of print, you can do that when it's a function but not when it's a statement.

We had been getting similar error messages while processing an Analysis Services database. It turned out that the username, which was used to run the Analysis Services instance, had not been added to the SQL Server's Security Logins.

In SQL Server 2012, the SQL Server and Analysis services are configured to run as different users by default. If you have gone with the defaults, always ensure that the AS user has access to your datasource!

Explicit access to module level variables by accessing them explicity on the module

In short: The technique described here is the same as in steveha's answer, except, that no artificial helper object is created to explicitly scope variables. Instead the module object itself is given a variable pointer, and therefore provides explicit scoping upon access from everywhere. (like assignments in local function scope).

Think of it like self for the current module instead of the current instance !

# db.py
import sys

# this is a pointer to the module object instance itself.
this = sys.modules[__name__]

# we can explicitly make assignments on it 
this.db_name = None

def initialize_db(name):
    if (this.db_name is None):
        # also in local function scope. no scope specifier like global is needed
        this.db_name = name
        # also the name remains free for local use
        db_name = "Locally scoped db_name variable. Doesn't do anything here."
    else:
        msg = "Database is already initialized to {0}."
        raise RuntimeError(msg.format(this.db_name))

As modules are cached and therefore import only once, you can import db.py as often on as many clients as you want, manipulating the same, universal state:

# client_a.py
import db

db.initialize_db('mongo')

# client_b.py
import db

if (db.db_name == 'mongo'):
    db.db_name = None  # this is the preferred way of usage, as it updates the value for all clients, because they access the same reference from the same module object

# client_c.py
from db import db_name
# be careful when importing like this, as a new reference "db_name" will
# be created in the module namespace of client_c, which points to the value 
# that "db.db_name" has at import time of "client_c".

if (db_name == 'mongo'):  # checking is fine if "db.db_name" doesn't change
    db_name = None  # be careful, because this only assigns the reference client_c.db_name to a new value, but leaves db.db_name pointing to its current value.

As an additional bonus I find it quite pythonic overall as it nicely fits Pythons policy of Explicit is better than implicit.

I'm coming from late 2016 and this code just works in recent versions of jquery (jquery-2.1.3.js in this case).

if ($(element).is("input")) {
    $(element).focus(function () {
        $(element).select();
    });
}

Here is another approach using getter and setter functions for the model.

@Component({
  selector: 'input-language',
  template: `
  …
  <input 
    type="text" 
    placeholder="Language" 
    [(ngModel)]="query" 
  />
  `,
})
export class InputLanguageComponent {

  set query(value) {
    this._query = value;
    console.log('query set to :', value)
  }

  get query() {
    return this._query;
  }
}

this will also work, if you like

 xcopy  C:\Test\Log "c:\Test\Backup-%date:~4,2%-%date:~7,2%-%date:~10,4%_%time:~0,2%%time:~3,2%" /s /i
 del C:\Test\Log

While I think the regex-based solution is probably the way I'd go, I'd be tempted to encapsulate this in a type.

public class AlphaNumericString
{
    public AlphaNumericString(string s)
    {
        Regex r = new Regex("^[a-zA-Z0-9]*$");
        if (r.IsMatch(s))
        {
            value = s;                
        }
        else
        {
            throw new ArgumentException("Only alphanumeric characters may be used");
        }
    }

    private string value;
    static public implicit operator string(AlphaNumericString s)
    {
        return s.value;
    }
}

Now, when you need a validated string, you can have the method signature require an AlphaNumericString, and know that if you get one, it is valid (apart from nulls). If someone attempts to pass in a non-validated string, it will generate a compiler error.

You can get fancier and implement all of the equality operators, or an explicit cast to AlphaNumericString from plain ol' string, if you care.

It is important to set contentType to 'application/x-www-form-urlencoded; charset=utf-8' or just omit contentTypefrom the object ...

Here's a demo.

EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:

if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {

Here's a demo.

Suppose you want to create a vector x whose length is zero. Now let v be any vector.

> v<-c(4,7,8)
> v
[1] 4 7 8
> x<-v[0]
> length(x)

I know OP asked about the utils::read.csv function, but let me provide an answer for these that come here searching how to do it using readr::read_csv from the tidyverse.

read_csv ("test.csv", col_names=FALSE, col_types = cols (.default = "c", time = "i"))

This should set the default type for all columns as character, while time would be parsed as integer.

var obj = {"a": "test1", "b": "test2"};
var getValuesOfObject = Object.values(obj)
for(index = 0; index < getValuesOfObject.length; index++){
    return Boolean(getValuesOfObject[index] === "test1")
}

The Object.values() method returned an array (assigned to getValuesOfObject) containing the given object's (obj) own enumerable property values. The array was iterated using the for loop to retrieve each value (values in the getValuesfromObject) and returns a Boolean() function to find out if the expression ("text1" is a value in the looping array) is true.

You said you are attempting to get the text from a div and store it on local storage.

Please Note: Text and Html are different. In the question you mentioned text. html() will return Html content like <a>example</a>. if you want to get Text content then you have to use text() instead of html() then the result will be example instead of <a>example<a>. Anyway, I am using your terminology let it be Text.

Step 1: get the text from div.

what you did is not get the text from div but set the text to a div.

$('#test').html("Test"); 

is actually setting text to div and the output will be a jQuery object. That is why it sets it as [object Object].

To get the text you have to write like this
$('#test').html();

This will return a string not an object so the result will be Test in your case.

Step 2: set it to local storage.

Your approach is correct and you can write it as

localStorage.key=value

But the preferred approach is

localStorage.setItem(key,value); to set

localStorage.getItem(key); to get.

key and value must be strings.

so in your context code will become

$('#test').html("Test");
localStorage.content = $('#test').html();
$('#test').html(localStorage.content);

But I don't find any meaning in your code. Because you want to get the text from div and store it on local storage. And again you are reading the same from local storage and set to div. just like a=10; b=a; a=b;

If you are facing any other problems please update your question accordingly.

If you want to use data binding you can follow this solution The following solution might be a better one to follow. the layout is in fragment_my.xml

<data>
    <variable
        name="listener"
        type="my_package.MyListener" />
</data>

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <Button
        android:id="@+id/moreTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="@{() -> listener.onClick()}"
        android:text="@string/login"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

class MyFragment : Fragment(), MyListener {
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
            return FragmentMyBinding.inflate(
                inflater,
                container,
                false
            ).apply {
                lifecycleOwner = viewLifecycleOwner
                listener = this@MyFragment
            }.root
    }

    override fun onClick() {
        TODO("Not yet implemented")
    }

}

interface MyListener{
    fun onClick()
}

You can use the custom TextView for whole app with custom font here is an example for that

public class MyTextView extends TextView {

   Typeface normalTypeface = Typeface.createFromAsset(getContext().getAssets(), Constants.FONT_REGULAR);
   Typeface boldTypeface = Typeface.createFromAsset(getContext().getAssets(),  Constants.FONT_BOLD);

   public MyTextView(Context context, AttributeSet attrs, int defStyle) {
       super(context, attrs, defStyle);
   }

   public MyTextView(Context context, AttributeSet attrs) {
       super(context, attrs);
   }

   public MyTextView(Context context) {
       super(context);
   }

   public void setTypeface(Typeface tf, int style) {
       if (style == Typeface.BOLD) {
           super.setTypeface(boldTypeface/*, -1*/);
       } else {
           super.setTypeface(normalTypeface/*, -1*/);
       }
   }
}

The recent versions of XAMPP for Windows runs PHP 7.x which are NOT compatible with mbcrypt. If you have a package like Laravel that requires mbcrypt, you will need to install an older version of XAMPP. OR, you can run XAMPP with multiple versions of PHP by downloading a PHP package from Windows.PHP.net, installing it in your XAMPP folder, and configuring php.ini and httpd.conf to use the correct version of PHP for your site.

Firstly enter cmd.

Then write:

sc delete MySQL  

After that restart your computer. When restarting your computer and opening your xampp, you can see cross symbol on the MySQL. Click the cross symbol and click the start. That's all.

Put the line in a stringstream and extract word by word back:

#include <iostream>
#include <sstream>
using namespace std;

int main()
{
    string t;
    getline(cin,t);

    istringstream iss(t);
    string word;
    while(iss >> word) {
        /* do stuff with word */
    }
}

Of course, you can just skip the getline part and read word by word from cin directly.

And here you can read why is using namespace std considered bad practice.

You could try running a script as follows

var WindowStyle_Hidden = 0
var objShell = WScript.CreateObject("WScript.Shell")
var result = objShell.Run("cmd.exe /c setrbvars.bat", WindowStyle_Hidden)

save the file as filename.js

It helped me. Just add it in your pom.xml.

By default maven compiler plugin uses Java 1.5 or 1.6, you have to redefine it in your pom.xml.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

You can also use a JXLabel from the SwingX library.

JXLabel multiline = new JXLabel("this is a \nMultiline Text");
multiline.setLineWrap(true);

Locale-independent one liner to get any date format you like. I use it to generate archive names. Back quote option is needed because PowerShell command line is using single quotes.

:: Get date in yyyyMMdd_HHmm format to use with file name.
FOR /f "usebackq" %%i IN (`PowerShell ^(Get-Date^).ToString^('yyyy-MM-dd'^)`) DO SET DTime=%%i

:: Get formatted yesterday date.
FOR /f "usebackq" %%i IN (`PowerShell ^(Get-Date^).AddDays^(-1^).ToString^('yyyy-MM-dd'^)`) DO SET DTime=%%i

:: Show file name with the date.
echo Archive.%DTime%.zip

This part of PowerShell is probably the most stupid aspect. Any extraneous output generated during a function will pollute the result. Sometimes there isn't any output, and then under some conditions there is some other unplanned output, in addition to your planned return value.

So, I remove the assignment from the original function call, so the output ends up on the screen, and then step through until something I didn't plan for pops out in the debugger window (using the PowerShell ISE).

Even things like reserving variables in outer scopes cause output, like [boolean]$isEnabled which will annoyingly spit a False out unless you make it [boolean]$isEnabled = $false.

Another good one is $someCollection.Add("thing") which spits out the new collection count.

isfar<-load("C:/Users/isfar.RData") 
if(is.data.frame(isfar)){
   names(isfar)
}

If isfar is a dataframe, this will print out the names of its columns.

Firstly, null the data source:

this.dataGridView.DataSource = null;

Then clear the rows:

this.dataGridView.Rows.Clear();

Then set the data source to the new list:

this.dataGridView.DataSource = this.GetNewValues();

Refer django docs on static files.

In settings.py:

import os
CURRENT_PATH = os.path.abspath(os.path.dirname(__file__).decode('utf-8'))

MEDIA_ROOT = os.path.join(CURRENT_PATH, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (
                    os.path.join(CURRENT_PATH, 'static'),
)

Then place your js and css files static folder in your project. Not in media folder.

In views.py:

from django.shortcuts import render_to_response, RequestContext

def view_name(request):
    #your stuff goes here
    return render_to_response('template.html', locals(), context_instance = RequestContext(request))

In template.html:

<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
<script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>

In urls.py:

from django.conf import settings
urlpatterns += patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

You can use memset, but only because our selection of types is restricted to integral types.

In general case in C it makes sense to implement a macro

#define ZERO_ANY(T, a, n) do{\
   T *a_ = (a);\
   size_t n_ = (n);\
   for (; n_ > 0; --n_, ++a_)\
     *a_ = (T) { 0 };\
} while (0)

This will give you C++-like functionality that will let you to "reset to zeros" an array of objects of any type without having to resort to hacks like memset. Basically, this is a C analog of C++ function template, except that you have to specify the type argument explicitly.

On top of that you can build a "template" for non-decayed arrays

#define ARRAY_SIZE(a) (sizeof (a) / sizeof *(a))
#define ZERO_ANY_A(T, a) ZERO_ANY(T, (a), ARRAY_SIZE(a))

In your example it would be applied as

int a[100];

ZERO_ANY(int, a, 100);
// or
ZERO_ANY_A(int, a);

It is also worth noting that specifically for objects of scalar types one can implement a type-independent macro

#define ZERO(a, n) do{\
   size_t i_ = 0, n_ = (n);\
   for (; i_ < n_; ++i_)\
     (a)[i_] = 0;\
} while (0)

and

#define ZERO_A(a) ZERO((a), ARRAY_SIZE(a))

turning the above example into

 int a[100];

 ZERO(a, 100);
 // or
 ZERO_A(a);

I got here with an MS Access problem.

Backticks are good for MySQL, but they create weird errors, like "Invalid Query Name: Query1" in MS Access, for MS Access only, use square brackets:

It should look like this

SELECT Customer.[Customer ID], Customer.[Full Name] ...

Might be a problem with date configuration on server side or on client side. I've found this to be a common problem on multiple databases when the host is configured in spanish, french or whatever... that could affect the format dd/mm/yyyy or mm/dd/yyyy.

It seems that k8s expects us to provide a different image tag for every deployment. My default strategy would be to make the CI system generate and push the docker images, tagging them with the build number: xpmatteo/foobar:456.

For local development it can be convenient to use a script or a makefile, like this:

# create a unique tag    
VERSION:=$(shell date +%Y%m%d%H%M%S)
TAG=xpmatteo/foobar:$(VERSION)

deploy:
    npm run-script build
    docker build -t $(TAG) . 
    docker push $(TAG)
    sed s%IMAGE_TAG_PLACEHOLDER%$(TAG)% foobar-deployment.yaml | kubectl apply -f - --record

The sed command replaces a placeholder in the deployment document with the actual generated image tag.

Here is the correct solution using list comprehensions (they're backward in the question):

>>> join = lambda it: (y for x in it for y in x)
>>> list(join([[1,2],[3,4,5],[]]))
[1, 2, 3, 4, 5]

In your case it would be

[image for menuitem in list_of_menuitems for image in menuitem.image_set.all()]

or you could use join and say

join(menuitem.image_set.all() for menuitem in list_of_menuitems)

In either case, the gotcha was the nesting of the for loops.

You can't verify (with enough accuracy to rely on) if an email actually exists using just a single PHP method. You can send an email to that account, but even that alone won't verify the account exists (see below). You can, at least, verify it's at least formatted like one

if(filter_var($email, FILTER_VALIDATE_EMAIL)) {
    //Email is valid
}

You can add another check if you want. Parse the domain out and then run checkdnsrr

if(checkdnsrr($domain)) {
     // Domain at least has an MX record, necessary to receive email
}

Many people get to this point and are still unconvinced there's not some hidden method out there. Here are some notes for you to consider if you're bound and determined to validate email:

1. Spammers also know the "connection trick" (where you start to send an email and rely on the server to bounce back at that point). One of the other answers links to this library which has this caveat

   Some mail servers will silently reject the test message, to prevent spammers from checking against their users' emails and filter the valid emails, so this function might not work properly with all mail servers.

   In other words, if there's an invalid address you might not get an invalid address response. In fact, virtually all mail servers come with an option to accept all incoming mail (here's how to do it with Postfix). The answer linking to the validation library neglects to mention that caveat.

2. Spam blacklists. They blacklist by IP address and if your server is constantly doing verification connections you run the risk of winding up on Spamhaus or another block list. If you get blacklisted, what good does it do you to validate the email address?

3. If it's really that important to verify an email address, the accepted way is to force the user to respond to an email. Send them a full email with a link they have to click to be verified. It's not spammy, and you're guaranteed that any responses have a valid address.

Suddenly, without any major change in my project, I too got this error.

All the above did not work for me, since I needed both the support libs V4 and V7.

At the end, because 2 hours ago the project compiled with no problems, I simply told Android Studio to REBUILD the project, and the error was gone.

Try the following:

df[df['Col2'].isnull()]

i achieved this by:

import { ImageBackground } from 'react-native';

<ImageBackground style={ styles.imgBackground } 
                 resizeMode='cover' 
                 source={require('./Your/Path.png')}>

   //place your now nested component JSX code here

</ImageBackground>

And then the Styles:

imgBackground: {
        width: '100%',
        height: '100%',
        flex: 1 
},

I had similar issue, but in the end I found out that ~/.bashrc was all I needed.

However, in Ubuntu, I had to comment the line that stops processing ~/.bashrc :

#If not running interactively, don't do anything
[ -z "$PS1" ] && return

Dim f as Range

Set f=ActiveSheet.Cells.Find(...)

If Not f Is Nothing then
    msgbox "Row=" & f.Row & vbcrlf & "Column=" & f.Column
Else
    msgbox "value not found!"
End If

Have you tried the arrange > auto arrange function in MySQL Workbench. It may save you from manually moving the tables around.

<input type="file" id="mfile" name="mfile">
<p>Reset</p>

<script>
$(document).ready(function(){
$("p").click(function(){

            $("#mfile").val('');
            return false;

    });
});

Your setMaxResults($limit) needs to be set on the object.

e.g.

$query_ids = $this->getEntityManager()
  ->createQuery(
    "SELECT e_.id
    FROM MuzichCoreBundle:Element e_
    WHERE [...]
    GROUP BY e_.id")
;
$query_ids->setMaxResults($limit);

The following worked for me.

var temp = ctx.Set<DbTable>()
  .GroupBy(g => new { g.id })
  .ToDictionary(d => d.Key.id);

Stored procedures:

(+)

• Great flexibility
• Full control over SQL
• The highest performance available

(-)

• Requires knowledge of SQL
• Stored procedures are out of source control
• Substantial amount of "repeating yourself" while specifying the same table and field names. The high chance of breaking the application after renaming a DB entity and missing some references to it somewhere.
• Slow development

ORM:

(+)

• Rapid development
• Data access code now under source control
• You're isolated from changes in DB. If that happens you only need to update your model/mappings in one place.

(-)

• Performance may be worse
• No or little control over SQL the ORM produces (could be inefficient or worse buggy). Might need to intervene and replace it with custom stored procedures. That will render your code messy (some LINQ in code, some SQL in code and/or in the DB out of source control).
• As any abstraction can produce "high-level" developers having no idea how it works under the hood

The general tradeoff is between having a great flexibility and losing lots of time vs. being restricted in what you can do but having it done very quickly.

There is no general answer to this question. It's a matter of holy wars. Also depends on a project at hand and your needs. Pick up what works best for you.

I think I know where your question is headed. And since this question is the one that pop ups in google's search main results, I can give a plain answer on what the @Valid annotation does.

I'll present 3 scenarios on how I've used @Valid

Model:

public class Employee{
private String name;
@NotNull(message="cannot be null")
@Size(min=1, message="cannot be blank")
private String lastName;
 //Getters and Setters for both fields.
 //...
}

JSP:

...
<form:form action="processForm" modelAttribute="employee">
 <form:input type="text" path="name"/>
 <br>
 <form:input type="text" path="lastName"/>
<form:errors path="lastName"/>
<input type="submit" value="Submit"/>
</form:form>
...

Controller for scenario 1:

     @RequestMapping("processForm")
        public String processFormData(@Valid @ModelAttribute("employee") Employee employee){
        return "employee-confirmation-page";
    }

In this scenario, after submitting your form with an empty lastName field, you'll get an error page since you're applying validation rules but you're not handling it whatsoever.

Example of said error: Exception page

Controller for scenario 2:

 @RequestMapping("processForm")
    public String processFormData(@Valid @ModelAttribute("employee") Employee employee,
BindingResult bindingResult){
                return bindingResult.hasErrors() ? "employee-form" : "employee-confirmation-page";
            }

In this scenario, you're passing all the results from that validation to the bindingResult, so it's up to you to decide what to do with the validation results of that form.

Controller for scenario 3:

@RequestMapping("processForm")
    public String processFormData(@Valid @ModelAttribute("employee") Employee employee){
                return "employee-confirmation-page";
            }
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public Map<String, String> invalidFormProcessor(MethodArgumentNotValidException ex){
  //Your mapping of the errors...etc
}

In this scenario you're still not handling the errors like in the first scenario, but you pass that to another method that will take care of the exception that @Valid triggers when processing the form model. Check this see what to do with the mapping and all that.

To sum up: @Valid on its own with do nothing more that trigger the validation of validation JSR 303 annotated fields (@NotNull, @Email, @Size, etc...), you still need to specify a strategy of what to do with the results of said validation.

Hope I was able to clear something for people that might stumble with this.

Below is the method using RouteData to style menuBar items depending of the current route:

RouteConfig includes data with tab (current route):

@RouteConfig([
  {
    path: '/home',    name: 'Home',    component: HomeComponent,
    data: {activeTab: 'home'},  useAsDefault: true
  }, {
    path: '/jobs',    name: 'Jobs',    data: {activeTab: 'jobs'},
    component: JobsComponent
  }
])

A piece of layout:

  <li role="presentation" [ngClass]="{active: isActive('home')}">
    <a [routerLink]="['Home']">Home</a>
  </li>
  <li role="presentation" [ngClass]="{active: isActive('jobs')}">
    <a [routerLink]="['Jobs']">Jobs</a>
  </li>

Class:

export class MainMenuComponent {
  router: Router;

  constructor(data: Router) {
    this.router = data;
  }

  isActive(tab): boolean {
    if (this.router.currentInstruction && this.router.currentInstruction.component.routeData) {
      return tab == this.router.currentInstruction.component.routeData.data['activeTab'];
    }
    return false;
  }
}

A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.

Eg

Private Sub worksheet_change(ByVal target As Range)
  target.Font.Bold = True
End Sub

Here is another ES2015 solution, works with objects and arrays.

function deepMerge(...sources) {
  let acc = {}
  for (const source of sources) {
    if (source instanceof Array) {
      if (!(acc instanceof Array)) {
        acc = []
      }
      acc = [...acc, ...source]
    } else if (source instanceof Object) {
      for (let [key, value] of Object.entries(source)) {
        if (value instanceof Object && key in acc) {
          value = deepMerge(acc[key], value)
        }
        acc = { ...acc, [key]: value }
      }
    }
  }
  return acc
}

// Test:

const A = {
 a: [null, {a:undefined}, [null,new Date()], {a(){}}],
 b: [1,2],
 c: {a:1, b:2}
}

const B = {
 a: ["new", 9],
 b: [new Date()],
 c: {a:{}, c:[]}
}

console.log(
  deepMerge(A,B)
)

Of course there IS a way to create files without opening. It's as easy as calling os.mknod("newfile.txt"). The only drawback is that this call requires root privileges on OSX.

primes = {x for x in range(2, 101) if all(x%y for y in range(2, min(x, 11)))}

I simplified the test a bit - if all(x%y instead of if not any(not x%y

I also limited y's range; there is no point in testing for divisors > sqrt(x). So max(x) == 100 implies max(y) == 10. For x <= 10, y must also be < x.

pairs = {(x, x+2) for x in primes if x+2 in primes}

Instead of generating pairs of primes and testing them, get one and see if the corresponding higher prime exists.

You should remove navbar-fixed-top class otherwise navbar stays fixed on top of page where you want logo.

If you want to place logo inside navbar:

Navbar height (set in @navbarHeight LESS variable) is 40px by default. Your logo has to fit inside or you have to make navbar higher first.

Then use brand class:

<div class="navbar navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container">
      <a href="/" class="brand"><img alt="" src="/logo.gif" /></a>
    </div>
  </div>
</div>

If your logo is higher than 20px, you have to fix stylesheets as well.

If you do that in LESS:

.navbar .brand {
  @elementHeight: 32px;
  padding: ((@navbarHeight - @elementHeight) / 2 - 2) 20px ((@navbarHeight - @elementHeight) / 2 + 2);

Padding calculation is taken from Twitter Bootstrap LESS - https://github.com/twitter/bootstrap/blob/v2.0.4/less/navbar.less#L51-52

Alternatively you can calculate padding values yourself and use pure CSS.

This works for Twitter Bootstrap versions 2.0.x, should work in 2.1 as well, but padding calculation was changed a bit: https://github.com/twitter/bootstrap/blob/v2.1.0/less/navbar.less#L50

Personally, window.postMessage is the most reliable way that I've found for modern browsers. You do have to do a slight bit more work to make sure you're not leaving yourself open to XSS attacks, but it's a reasonable tradeoff.

There are also several plugins for the popular Javascript toolkits out there that wrap window.postMessage that provide similar functionality to older browsers using the other methods discussed above.

It's possible to get this done using seaborn.lineplot() but it involves some additional work of converting numpy arrays to pandas dataframe. Here's a complete example:

# imports
import seaborn as sns
import numpy as np
import pandas as pd

# inputs
In [41]: num = np.array([1, 2, 3, 4, 5])
In [42]: sqr = np.array([1, 4, 9, 16, 25])

# convert to pandas dataframe
In [43]: d = {'num': num, 'sqr': sqr}
In [44]: pdnumsqr = pd.DataFrame(d)

# plot using lineplot
In [45]: sns.set(style='darkgrid')
In [46]: sns.lineplot(x='num', y='sqr', data=pdnumsqr)
Out[46]: <matplotlib.axes._subplots.AxesSubplot at 0x7f583c05d0b8>

And we get the following plot:

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

If you're looking for a solution that returns proper number or days between e.g. 11/30/2014 23:59 and 12/01/2014 00:01 here's solution using Joda Time.

private int getDayDifference(long past, long current) {
    DateTime currentDate = new DateTime(current);
    DateTime pastDate = new DateTime(past);
    return currentDate.getDayOfYear() - pastDate.getDayOfYear();
} 

This implementation will return 1 as a difference in days. Most of the solutions posted here calculate difference in milliseconds between two dates. It means that 0 would be returned because there's only 2 minutes difference between these two dates.

Given this data:

Col1  Col2  Col3
 A     X     1
 A     Y     2
 A     Y     3
 B     X     0
 B     Y     3
 B     Z     1

This query:

SELECT Col1, Col2, Col3 FROM data GROUP BY Col1, Col2, Col3

Would result in exactly the same table.

However, this query:

SELECT Col1, Col2 FROM data GROUP BY Col1, Col2

Would result in:

Col1  Col2
 A     X  
 A     Y  
 B     X  
 B     Y  
 B     Z  

Now, a query:

SELECT Col1, Col2, Col3 FROM data GROUP BY Col1, Col2

Would create a problem: the line with A, Y is the result of grouping the two lines

 A     Y     2
 A     Y     3

So, which value should be in Col3, '2' or '3'?

Normally you would use a GROUP BY to calculate e.g. a sum:

SELECT Col1, Col2, SUM(Col3) FROM data GROUP BY Col1, Col2

So in the line, we had a problem with we now get (2+3) = 5.

Grouping by all your columns in your select is effectively the same as using DISTINCT, and it is preferable to use the DISTINCT keyword word readability in this case.

So instead of

SELECT Col1, Col2, Col3 FROM data GROUP BY Col1, Col2, Col3

use

SELECT DISTINCT Col1, Col2, Col3 FROM data

I found this more useful for getting the absolute file location.

File file = new File("\\TestHello\\test.txt");
System.out.println(file.getAbsoluteFile());

The easiest way to set an environment variable in CentOS is to use export as in

$> export JAVA_HOME=/usr/java/jdk.1.5.0_12

$> export PATH=$PATH:$JAVA_HOME

However, variables set in such a manner are transient i.e. they will disappear the moment you exit the shell. Obviously this is not helpful when setting environment variables that need to persist even when the system reboots. In such cases, you need to set the variables within the system wide profile. In CentOS (I’m using v5.2), the folder /etc/profile.d/ is the recommended place to add customizations to the system profile. For example, when installing the Sun JDK, you might need to set the JAVA_HOME and JRE_HOME environment variables. In this case: Create a new file called java.sh

vim /etc/profile.d/java.sh

Within this file, initialize the necessary environment variables

export JRE_HOME=/usr/java/jdk1.5.0_12/jre
export PATH=$PATH:$JRE_HOME/bin

export JAVA_HOME=/usr/java/jdk1.5.0_12
export JAVA_PATH=$JAVA_HOME

export PATH=$PATH:$JAVA_HOME/bin

Now when you restart your machine, the environment variables within java.sh will be automatically initialized (checkout /etc/profile if you are curious how the files in /etc/profile.d/ are loaded).

PS: If you want to load the environment variables within java.sh without having to restart the machine, you can use the source command as in:

$> source java.sh

Thanks Rich, I will take note of that. So here is the script for my own solution. It requires no third party unzip tools.

I use WinForms and my way to use File.Exists(string path) is the next one:

public bool FileExists(string fileName)
{
    var workingDirectory = Environment.CurrentDirectory;
    var file = $"{workingDirectory}\{fileName}";
    return File.Exists(file);
}

fileName must include the extension like myfile.txt

You can try cactoos for that.

final InputStream input = new InputStreamOf("example");

The object is created with new and not a static method for a reason.

Depending on the implementation. it's possible that an array of primitive types will be smaller and more efficient than ArrayList. This is because the array will store the values directly in a contiguous block of memory, while the simplest ArrayList implementation will store pointers to each value. On a 64-bit platform especially, this can make a huge difference.

Of course, it's possible for the jvm implementation to have a special case for this situation, in which case the performance will be the same.

Wow, everybody is such a pessimist around here. The answer is yes.

It ain't trivial: by the end, we'll have the core function, a supporting struct, a wrapper function, and a macro around the wrapper function. In my work I have a set of macros to automate all this; once you understand the flow it'll be easy for you to do the same.

I've written this up elsewhere, so here's a detailed external link to supplement the summary here: http://modelingwithdata.org/arch/00000022.htm

We'd like to turn

double f(int i, double x)

into a function that takes defaults (i=8, x=3.14). Define a companion struct:

typedef struct {
    int i;
    double x;
} f_args;

Rename your function f_base, and define a wrapper function that sets defaults and calls the base:

double var_f(f_args in){
    int i_out = in.i ? in.i : 8;
    double x_out = in.x ? in.x : 3.14;
    return f_base(i_out, x_out);
}

Now add a macro, using C's variadic macros. This way users don't have to know they're actually populating a f_args struct and think they're doing the usual:

#define f(...) var_f((f_args){__VA_ARGS__});

OK, now all of the following would work:

f(3, 8);      //i=3, x=8
f(.i=1, 2.3); //i=1, x=2.3
f(2);         //i=2, x=3.14
f(.x=9.2);    //i=8, x=9.2

Check the rules on how compound initializers set defaults for the exact rules.

One thing that won't work: f(0), because we can't distinguish between a missing value and zero. In my experience, this is something to watch out for, but can be taken care of as the need arises---half the time your default really is zero.

I went through the trouble of writing this up because I think named arguments and defaults really do make coding in C easier and even more fun. And C is awesome for being so simple and still having enough there to make all this possible.

The problem for me was that somehow it could really not find the apk, while the apk exists.

The APK file /Users/Paul/AndroidStudioProjects/android-tv-launcher/ui/build/outputs/apk/nameofapk.apk does not exist on disk.
Error while Installing APK

All I had to do, was right click on the apk-copy relative path, and just

adb install -r <paste of relative path>

And the apk was installed and good to go. This issue happened on OSX for me.

this also worked for me. Go to the bootstrap-datepicker.js.

replace this code :

var defaults = $.fn.datepicker.defaults = {_x000D_
  autoclose: false,_x000D_
  beforeShowDay: $.noop,_x000D_
  calendarWeeks: false,_x000D_
  clearBtn: false,_x000D_
  daysOfWeekDisabled: [],_x000D_
  endDate: Infinity,_x000D_
  forceParse: true,_x000D_
  format: 'mm/dd/yyyy',_x000D_
  keyboardNavigation: true,_x000D_
  language: 'en',_x000D_
  minViewMode: 0,_x000D_
  multidate: false,_x000D_
  multidateSeparator: ',',_x000D_
  orientation: "auto",_x000D_
  rtl: false,_x000D_
  startDate: -Infinity,_x000D_
  startView: 0,_x000D_
  todayBtn: false,_x000D_
  todayHighlight: false,_x000D_
  weekStart: 0_x000D_
 };

with :

var defaults = $.fn.datepicker.defaults = {_x000D_
  autoclose: false,_x000D_
  beforeShowDay: $.noop,_x000D_
  calendarWeeks: false,_x000D_
  clearBtn: false,_x000D_
  daysOfWeekDisabled: [],_x000D_
  endDate: Infinity,_x000D_
  forceParse: true,_x000D_
  format: 'yyyy-mm-dd',_x000D_
  keyboardNavigation: true,_x000D_
  language: 'en',_x000D_
  minViewMode: 0,_x000D_
  multidate: false,_x000D_
  multidateSeparator: ',',_x000D_
  orientation: "auto",_x000D_
  rtl: false,_x000D_
  startDate: -Infinity,_x000D_
  startView: 0,_x000D_
  todayBtn: false,_x000D_
  todayHighlight: false,_x000D_
  weekStart: 0_x000D_
 };

The command to change the shell at startup is chsh -s <path_to_shell>. The default shells in mac OS X are installed inside the bin directory so if you want to change to the default zsh then you would use the following

chsh -s /bin/zsh

If you're using different version of zsh then you might have to add that version to /etc/shells to avoid the nonstandard shell message. For example if you want home-brew's version of zsh then you have to add /usr/local/bin/zsh to the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" and then run

chsh -s /usr/local/bin/zsh

Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed

sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" && chsh -s /usr/local/bin/zsh

Firstly, just to remind you there is a logical error you better keep result=1 or else your output will be result=0 even after the loop runs.

Secondly you can write it like this:

import sys

def Factorial(n): # Return factorial
  result = 0
  for i in range (1,n):
     result = result * i

  print "factorial is ",result
  return result

Leaving a line will tell the python shell that the FOR statements have ended. If you have experience using the python shell then you can understand why we have to leave a line.

1752 was the year of Britain switching from the Julian to the Gregorian calendar. I believe two weeks in September 1752 never happened as a result, which has implications for dates in that general area.

An explanation: http://uneasysilence.com/archive/2007/08/12008/ (Internet Archive version)

>>> from datetime import datetime

>>>  a = datetime.now()

# wait a bit 
>>> b = datetime.now()

>>> d = b - a # yields a timedelta object
>>> d.seconds
7

(7 will be whatever amount of time you waited a bit above)

I find datetime.datetime to be fairly useful, so if there's a complicated or awkward scenario that you've encountered, please let us know.

EDIT: Thanks to @WoLpH for pointing out that one is not always necessarily looking to refresh so frequently that the datetimes will be close together. By accounting for the days in the delta, you can handle longer timestamp discrepancies:

>>> a = datetime(2010, 12, 5)
>>> b = datetime(2010, 12, 7)
>>> d = b - a
>>> d.seconds
0
>>> d.days
2
>>> d.seconds + d.days * 86400
172800

A Node.js and MongoDB solution

Since we know the format that MongoDB uses to create a new ObjectId with 12 bytes.

• a 4-byte value representing the seconds since the Unix epoch,
• a 3-byte machine identifier,
• a 2-byte process id
• a 3-byte counter (in your machine), starting with a random value.

Example (I choose a random sequence) a1b2c3d4e5f6g7h8i9j1k2l3

• a1b2c3d4 represents the seconds since the Unix epoch,
• 4e5f6g7 represents machine identifier,
• h8i9 represents process id
• j1k2l3 represents the counter, starting with a random value.

Since the counter will be unique if we are storing the data in the same machine we can get it with no doubts that it will be duplicate.

So the short URL will be the counter and here is a code snippet assuming that your server is running properly.

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

// Create a schema
const shortUrl = new Schema({
    long_url: { type: String, required: true },
    short_url: { type: String, required: true, unique: true },
  });
const ShortUrl = mongoose.model('ShortUrl', shortUrl);

// The user can request to get a short URL by providing a long URL using a form

app.post('/shorten', function(req ,res){
    // Create a new shortUrl */
    // The submit form has an input with longURL as its name attribute.
    const longUrl = req.body["longURL"];
    const newUrl = ShortUrl({
        long_url : longUrl,
        short_url : "",
    });
    const shortUrl = newUrl._id.toString().slice(-6);
    newUrl.short_url = shortUrl;
    console.log(newUrl);
    newUrl.save(function(err){
        console.log("the new URL is added");
    })
});

Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

I did it in this way:

1. Open GitHub application installed on Mac
2. Click on Advanced tab → Install command line tools
3. Once you get a message that all commands have been installed close your terminal and reopen it.
4. Now check git --version, it should give you the latest version.

JSON.stringify(err, Object.getOwnPropertyNames(err))

seems to work

[from a comment by /u/ub3rgeek on /r/javascript] and felixfbecker's comment below

You can't do it with client side script only... you could make an AJAX call to some server side code that will send an email...

You can use .empty(), like this:

$("#foo").empty();

From the docs:

Remove all child nodes of the set of matched elements from the DOM.

I suggest to you:

HttpClient.DefaultRequestHeaders.Add("Authorization", "Bearer <token>");

And then you can use it like that:

var response = await client.GetAsync(url);
if (response.IsSuccessStatusCode)
{
    responseMessage = await response.Content.ReadAsAsync<ResponseMessage>();
}

I kind of got things working by adding auto layout constraints:

But I am not happy with this. Took a lot of trial and error and couldn't understand why this worked.

Also I had to add to use titleLabel.numberOfLines = 0 in my ViewController

I faced this issue a lot when using position: absolute;, I faced this issue by using position: relative in the child element. don't need to change position: absolute to relative, just need to add in the child element look into the beneath two examples:

let toggle = document.getElementById('toggle')

toggle.addEventListener("click", () => {
 toggle.classList.toggle('change');
})

.container {
  width: 60px;
  height: 22px;
  background: #333;
  border-radius: 20px;
  position: relative;
  cursor: pointer;

}

.change .slide {
  transform: translateX(33px);
}

.slide {
  transition: 0.5s;
  width: 20px;
  height: 20px;
  background: #fff;
  border-radius: 20px;
  margin: 2px 2px;
  z-index: 100;
}

.dot {
  width: 10px;
  height: 16px;
  background: red;
  position: absolute;
  top: 4px;
  right: 5px;
  z-index: 1;
}

<div class="container" id="toggle">
  <div class="slide"></div>
  <div class="dot"></div>
</div>

This's how it can be fixed using position relative:

let toggle = document.getElementById('toggle')

toggle.addEventListener("click", () => {
 toggle.classList.toggle('change');
})

.container {
  width: 60px;
  height: 22px;
  background: #333;
  border-radius: 20px;
  position: relative;
  cursor: pointer;

}

.change .slide {
  transform: translateX(33px);
}

.slide {
  transition: 0.5s;
  width: 20px;
  height: 20px;
  background: #fff;
  border-radius: 20px;
  margin: 2px 2px;
  z-index: 100;
  
  // Just add position relative;
  position: relative;
}

.dot {
  width: 10px;
  height: 16px;
  background: red;
  position: absolute;
  top: 4px;
  right: 5px;
  z-index: 1;
}

<div class="container" id="toggle">
  <div class="slide"></div>
  <div class="dot"></div>
</div>

These all look a bit more complicated than they need to be. My code is very simple and fast:

def fibonacci(x):

    List = []
    f = 1
    List.append(f)
    List.append(f) #because the fibonacci sequence has two 1's at first
    while f<=x:
        f = List[-1] + List[-2]   #says that f = the sum of the last two f's in the series
        List.append(f)
    else:
        List.remove(List[-1])  #because the code lists the fibonacci number one past x. Not necessary, but defines the code better
        for i in range(0, len(List)):
        print List[i]  #prints it in series form instead of list form. Also not necessary

Here is an ES2017+ way to get the counts for all array items in O(N):

const arr = [1, 2, 3, 5, 2, 8, 9, 2];
const counts = {};

arr.forEach((el) => {
  counts[el] = counts[el] ? (counts[el] += 1) : 1;
});

You can also optionally sort the output:

const countsSorted = Object.entries(counts).sort(([_, a], [__, b]) => a - b);

console.log(countsSorted) for your example array:

[
  [ '2', 3 ],
  [ '1', 1 ],
  [ '3', 1 ],
  [ '5', 1 ],
  [ '8', 1 ],
  [ '9', 1 ]
]

Could you use jQuery, since it's cross-browser compatible?

function isOnScreen(element)
{
    var curPos = element.offset();
    var curTop = curPos.top;
    var screenHeight = $(window).height();
    return (curTop > screenHeight) ? false : true;
}

And then call the function using something like:

if(isOnScreen($('#myDivId'))) { /* Code here... */ };

You are incorrectly using Dependency Injection. The proper way is to have your controllers take the dependencies they need and leave to the dependency injection framework inject the concrete instances:

public class HomeController: Controller
{
    private readonly ISettingsManager settingsManager;
    public HomeController(ISettingsManager settingsManager)
    {
        this.settingsManager = settingsManager;
    }

    public ActionResult Index()
    {
        // you could use the this.settingsManager here
    }
}

As you can see in this example the controller doesn't know anything about the container. And that's how it should be.

All the DI wiring should happen in your Bootstraper. You should never use container.Resolve<> calls in your code.

As far as your error is concerned, probably the mUnityContainer you are using inside your controller is not the same instance as the one constructed in your Bootstraper. But since you shouldn't be using any container code in your controllers, this shouldn't be a problem anymore.

Place HiddenField Control in your Form.

<asp:HiddenField ID="hidden" runat="server" />

Create a Property in the Form

protected String LabelProperty
{
    get
    {
        return hidden.Value;
    }
    set
    {
        hidden.Value = value;
    }
}

Update the Hidden Field value from JavaScript

<script>
   function UpdateControl() {
            document.getElementById('<%=hidden.ClientID %>').value = '12';
   }
</script>

Now you can access the Property directly across the Postback. The Label Control updated value will be Lost across PostBack in case it is being used directly in code behind .

You can also set DirectoryIndex in apache's httpd.conf file.

CentOS keeps this file in /etc/httpd/conf/httpd.conf Debian: /etc/apache2/apache2.conf

Open the file in your text editor and find the line starting with DirectoryIndex

To load landing.html as a default (but index.html if that's not found) change this line to read:

DirectoryIndex  landing.html index.html

see http://editorconfig.org and https://docs.microsoft.com/en-us/visualstudio/ide/create-portable-custom-editor-options?view=vs-2017

1. If it does not exist, add a new file called .editorconfig for your project

2. manipulate editor config to use your preferred behaviour.

I prefer spaces over tabs, and CRLF for all code files.
Here's my .editorconfig

# http://editorconfig.org
root = true

[*]
indent_style = space
indent_size = 4
end_of_line = crlf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.md]
trim_trailing_whitespace = false

[*.tmpl.html]
indent_size = 4

[*.scss]
indent_size = 2 

Although systemd indeed does not provide way to pass command-line arguments for unit files, there are possibilities to write instances: http://0pointer.de/blog/projects/instances.html

For example: /lib/systemd/system/[email protected] looks something like this:

[Unit]
Description=Serial Getty on %I
BindTo=dev-%i.device
After=dev-%i.device systemd-user-sessions.service

[Service]
ExecStart=-/sbin/agetty -s %I 115200,38400,9600
Restart=always
RestartSec=0

So, you may start it like:

$ systemctl start [email protected]
$ systemctl start [email protected]

For systemd it will different instances:

$ systemctl status [email protected]
[email protected] - Getty on ttyUSB0
      Loaded: loaded (/lib/systemd/system/[email protected]; static)
      Active: active (running) since Mon, 26 Sep 2011 04:20:44 +0200; 2s ago
    Main PID: 5443 (agetty)
      CGroup: name=systemd:/system/[email protected]/ttyUSB0
          + 5443 /sbin/agetty -s ttyUSB0 115200,38400,9600

It also mean great possibility enable and disable it separately.

Off course it lack much power of command line parsing, but in common way it is used as some sort of config files selection. For example you may look at Fedora [email protected]: http://pkgs.fedoraproject.org/cgit/openvpn.git/tree/[email protected]

Use <property name="build.sysclasspath" value="last"/> in your build.xml file

For more details search includeAntRuntime in Ant javac

Other possible values could be found here

If you want to show all the rows set like bellow

pd.options.display.max_rows = None

If you want to show all columns set like bellow

pd.options.display.max_columns = None

Try running task manager to determine if your program is still running.

If it is running then stop it and run it again. the [Error] ld returned 1 exit status will not come back

There is now! I recently created a library, json-transforms, exactly for this purpose:

https://github.com/ColinEberhardt/json-transforms

It uses a combination of JSPath, a DSL modelled on XPath, and a recursive pattern matching approach, inspired directly by XSLT.

Here's a quick example. Given the following JSON object:

const json = {
  "automobiles": [
    { "maker": "Nissan", "model": "Teana", "year": 2011 },
    { "maker": "Honda", "model": "Jazz", "year": 2010 },
    { "maker": "Honda", "model": "Civic", "year": 2007 },
    { "maker": "Toyota", "model": "Yaris", "year": 2008 },
    { "maker": "Honda", "model": "Accord", "year": 2011 }
  ]
};

Here's a transformation:

const jsont = require('json-transforms');
const rules = [
  jsont.pathRule(
    '.automobiles{.maker === "Honda"}', d => ({
      Honda: d.runner()
    })
  ),
  jsont.pathRule(
    '.{.maker}', d => ({
      model: d.match.model,
      year: d.match.year
    })
  ),
  jsont.identity
];

const transformed  = jsont.transform(json, rules);

Which output the following:

{
  "Honda": [
    { "model": "Jazz", "year": 2010 },
    { "model": "Civic", "year": 2007 },
    { "model": "Accord", "year": 2011 }
  ]
}

This transform is composed of three rules. The first matches any automobile which is made by Honda, emitting an object with a Honda property, then recursively matching. The second rule matches any object with a maker property, outputting the model and year properties. The final is the identity transform that recursively matches.

A quick & concise difference overview :

attr_accessor is an easy way to create read and write accessors in your class. It is used when you do not have a column in your database, but still want to show a field in your forms. This field is a “virtual attribute” in a Rails model.

virtual attribute – an attribute not corresponding to a column in the database.

attr_accessible is used to identify attributes that are accessible by your controller methods makes a property available for mass-assignment.. It will only allow access to the attributes that you specify, denying the rest.

How about generate based on time stamp rounded to the nearest millisecond, or whatever accuracy you need... then use a lock to synchronize access to the function.

If you store the last generated file name, you can append sequential letters or further digits to it as needed to make it unique.

Or if you'd rather do it without locks, use a time step plus a thread ID, and make sure that the function takes longer than a millisecond, or waits so that it does.

Not sure if this help or not but this is a command line tool which let you simply send test mails from a SMTP server priodically. http://code.google.com/p/woodpecker-tester/

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

try this

 $(this).parent().css("backgroundImage", "url('../images/r-srchbg_white.png') no-repeat");

Vagrant-lxc is a plugin for Vagrant that let's you use LXC to provision Vagrant. It does not have all the features that the default vagrant VM (VirtualBox) has but it should allow you more flexibility than docker containers. There is a video in the link showing its capabilities that is worth watching.

I'd have to recommend NumPy as well

Not only is it faster for doing vector math, but it also has a ton of convenience functions.

If you want something even faster for 1d vectors, try vop

It's similar to MatLab, but free and stuff. Here's an example of what you'd do

from numpy import matrix
a = matrix((2,2,2))
b = matrix((1,1,1))
ret = a - b
print ret
>> [[1 1 1]]

Boom.

Simply try to multiply by one as following:

"00123" * 1;              // Get as number
"00123" * 1 + "";       // Get as string

There aren't any selector hacks for IE8. The best resource for this issue is http://browserhacks.com/#ie

If you want to target specific IE8 you should do comment in html

<!--[if IE 8]> Internet Explorer 8 <![endif]-->

or you could use attribute hacks like:

/* IE6, IE7, IE8, but also IE9 in some cases :( */
#diecinueve { color: blue\9; }

/* IE7, IE8 */
#veinte { color/*\**/: blue\9; }

/* IE8, IE9 */
#anotherone  {color: blue\0/;} /* must go at the END of all rules */

For more info on this one check: http://www.paulirish.com/2009/browser-specific-css-hacks/

My solution that would work on Chrome, Firefox, IE9, IE10 (Change the degrees as per your requirement):

.rotate-text {
  -webkit-transform: rotate(270deg);
  -moz-transform: rotate(270deg);
  -ms-transform: rotate(270deg);
  -o-transform: rotate(270deg);
  transform: rotate(270deg);
  filter: none; /*Mandatory for IE9 to show the vertical text correctly*/      
}

I had the same issue as @Gravity Grave whereby scrolling doesn't work if you use

data-toggle="modal" data-target="TARGET-2" 

in conjunction with

data-dismiss="modal"

The scroll doesn't work correctly and reverts to scrolling the page rather than the modal. This is due to data-dismiss removing the modal-open class from the tag.

My solution in the end was to set the html of the inner component on the modal and use css to fade the text in/out.

If you don't want to do this in a batch script, you can do this from the command line like this:

for %I in (test.jpg) do @echo %~zI

Ugly, but it works. You can also pass in a file mask to get a listing for more than one file:

for %I in (*.doc) do @echo %~znI

Will display the size, file name of each .DOC file.

Remember that in Python when you do:

    list1 = ['apples','bananas','pineapples']
    list2 = list1

List2 isn't storing the actual list, but a reference to list1. So when you do anything to list1, list2 changes as well. use the copy module (not default, download on pip) to make an original copy of the list(copy.copy() for simple lists, copy.deepcopy() for nested ones). This makes a copy that doesn't change with the first list.

I use the /^[a-z]+:[^:]+$/i regular expression for URL validation. See an example of my cross-browser InputKeyFilter code with URL validation.

Remove the semicolon ( ; ).

In oracle, you can use semicolon or not when u ran query directly on DB. But when u using java to ran a oracle query, u have to remove semicolon at the end.

The following will cover all browsers worth covering:

text-shadow: 0 0 2px #fff; /* Firefox 3.5+, Opera 9+, Safari 1+, Chrome, IE10 */
filter: progid:DXImageTransform.Microsoft.Glow(Color=#ffffff,Strength=1); /* IE<10 */

There are already answers which give how to change Inner HTML of element.

But I would suggest, you should use some animation like Fade Out/ Fade In to change HTML which gives good effect of changed HTML rather instantly changing inner HTML.

Use animation to change Inner HTML

$('#regTitle').fadeOut(500, function() {
    $(this).html('Hello World!').fadeIn(500);
});

If you have many functions which need this, then you can call common function which changes inner Html.

function changeInnerHtml(elementPath, newText){
    $(elementPath).fadeOut(500, function() {
        $(this).html(newText).fadeIn(500);
    });
}

Use the formula by tigeravatar:

=COUNTIF($B$2:$B$5,A2)>0 – tigeravatar Aug 28 '13 at 14:50

as conditional formatting. Highlight column A. Choose conditional formatting by forumula. Enter the formula (above) - this finds values in col B that are also in A. Choose a format (I like to use FILL and a bold color).

To find all of those values, highlight col A. Data > Filter and choose Filter by color.

This is the simplest example I can think of that conveys the rare cases where this feature is pertinent:

#include <iostream>

class bowl {
public:
    int apples;
    int oranges;
};

int count_fruit(bowl * begin, bowl * end, int bowl::*fruit)
{
    int count = 0;
    for (bowl * iterator = begin; iterator != end; ++ iterator)
        count += iterator->*fruit;
    return count;
}

int main()
{
    bowl bowls[2] = {
        { 1, 2 },
        { 3, 5 }
    };
    std::cout << "I have " << count_fruit(bowls, bowls + 2, & bowl::apples) << " apples\n";
    std::cout << "I have " << count_fruit(bowls, bowls + 2, & bowl::oranges) << " oranges\n";
    return 0;
}

The thing to note here is the pointer passed in to count_fruit. This saves you having to write separate count_apples and count_oranges functions.

Using the wildcard * selector in CSS to override inheritance for all attributes of an element (by setting these back to their initial state).

An example of its use:

li * {
   display: initial;
}

To bind a control to your state you need to call a function on the component that updates the state from the control's event handler.

Rather than have an update function for all your form fields, you could create a generic update function using ES6 computed name feature and pass it the values it needs inline from the control like this:

class LovelyForm extends React.Component {_x000D_
  constructor(props) {_x000D_
  alert("Construct");_x000D_
    super(props);_x000D_
    this.state = {_x000D_
      field1: "Default 1",_x000D_
      field2: "Default 2"_x000D_
    };_x000D_
  }_x000D_
_x000D_
  update = (name, e) => {_x000D_
    this.setState({ [name]: e.target.value });_x000D_
  }_x000D_
_x000D_
  render() {_x000D_
    return (_x000D_
      <form>_x000D_
        <p><input type="text" value={this.state.field1} onChange={(e) => this.update("field1", e)} />_x000D_
          {this.state.field1}</p>_x000D_
        <p><input type="text" value={this.state.field2} onChange={(e) => this.update("field2", e)} />_x000D_
          {this.state.field2}</p>_x000D_
      </form>_x000D_
    );_x000D_
  }_x000D_
}_x000D_

A variable is declared if accessing the variable name will not produce a ReferenceError. The expression typeof variableName !== 'undefined' will be false in only one of two cases:

• the variable is not declared (i.e., there is no var variableName in scope), or
• the variable is declared and its value is undefined (i.e., the variable's value is not defined)

Otherwise, the comparison evaluates to true.

If you really want to test if a variable is declared or not, you'll need to catch any ReferenceError produced by attempts to reference it:

var barIsDeclared = true; 
try{ bar; }
catch(e) {
    if(e.name == "ReferenceError") {
        barIsDeclared = false;
    }
}

If you merely want to test if a declared variable's value is neither undefined nor null, you can simply test for it:

if (variableName !== undefined && variableName !== null) { ... }

Or equivalently, with a non-strict equality check against null:

if (variableName != null) { ... }

Both your second example and your right-hand expression in the && operation tests if the value is "falsey", i.e., if it coerces to false in a boolean context. Such values include null, false, 0, and the empty string, not all of which you may want to discard.

I dont know why , but "pip install mechanize" didnt work for me . easy install worked anyway . Try this :

sudo easy_install mechanize

int days = 1;
var newDate = new Date(Date.now() + days*24*60*60*1000);

CodePen

var days = 2;_x000D_
var newDate = new Date(Date.now()+days*24*60*60*1000);_x000D_
_x000D_
document.write('Today: <em>');_x000D_
document.write(new Date());_x000D_
document.write('</em><br/> New: <strong>');_x000D_
document.write(newDate);

Suppose you have the following code:

import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

public class Test {
    public static void main(String[] s) {
        Map<String, Boolean> whoLetDogsOut = new ConcurrentHashMap<>();
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
    }
    static boolean f(String s) {
        System.out.println("creating a value for \""+s+'"');
        return s.isEmpty();
    }
}

Then you will see the message creating a value for "snoop" exactly once as on the second invocation of computeIfAbsent there is already a value for that key. The k in the lambda expression k -> f(k) is just a placeolder (parameter) for the key which the map will pass to your lambda for computing the value. So in the example the key is passed to the function invocation.

Alternatively you could write: whoLetDogsOut.computeIfAbsent("snoop", k -> k.isEmpty()); to achieve the same result without a helper method (but you won’t see the debugging output then). And even simpler, as it is a simple delegation to an existing method you could write: whoLetDogsOut.computeIfAbsent("snoop", String::isEmpty); This delegation does not need any parameters to be written.

To be closer to the example in your question, you could write it as whoLetDogsOut.computeIfAbsent("snoop", key -> tryToLetOut(key)); (it doesn’t matter whether you name the parameter k or key). Or write it as whoLetDogsOut.computeIfAbsent("snoop", MyClass::tryToLetOut); if tryToLetOut is static or whoLetDogsOut.computeIfAbsent("snoop", this::tryToLetOut); if tryToLetOut is an instance method.

AFAK there is no model.summary() like equivalent in pytorch

Meanwhile you can refer script by szagoruyko, which gives a nice visualizaton like in resnet18-example

Swift 3.0 - 4.0 version

do {

    //Convert to Data
    let jsonData = try JSONSerialization.data(withJSONObject: dictionaryOrArray, options: JSONSerialization.WritingOptions.prettyPrinted)

    //Convert back to string. Usually only do this for debugging
    if let JSONString = String(data: jsonData, encoding: String.Encoding.utf8) {
       print(JSONString)
    }

    //In production, you usually want to try and cast as the root data structure. Here we are casting as a dictionary. If the root object is an array cast as [Any].
    var json = try JSONSerialization.jsonObject(with: jsonData, options: JSONSerialization.ReadingOptions.mutableContainers) as? [String: Any]


} catch {
    print(error.description)
}

The JSONSerialization.WritingOptions.prettyPrinted option gives it to the eventual consumer in an easier to read format if they were to print it out in the debugger.

Reference: Apple Documentation

The JSONSerialization.ReadingOptions.mutableContainers option lets you mutate the returned array's and/or dictionaries.

Reference for all ReadingOptions: Apple Documentation

NOTE: Swift 4 has the ability to encode and decode your objects using a new protocol. Here is Apples Documentation, and a quick tutorial for a starting example.

very simple:

sudo chown mongodb:mongodb /var/lib/mongodb/mongod.lock 

I'm not sure if you mean knowing if it's a type string regardless of its contents, or whether it's contents is a number or string, regardless of its type.

So to know if its type is a string, that's already been answered.
But to know based on its contents if its a string or a number, I would use this:

function isNumber(item) {
    return (parseInt(item) + '') === item;
}

And for some examples:

isNumber(123);   //true
isNumber('123'); //true
isNumber('123a');//false
isNumber('');    //false

Use substring() and give the number of characters that you want to trim from front.

String value = "Jamaica";
value = value.substring(1);

Answer: "amaica"

Another reason why many prefer hyphens in CSS id and class names is functionality.

Using keyboard shortcuts like option + left/right (or ctrl+left/right on Windows) to traverse code word by word stops the cursor at each dash, allowing you to precisely traverse the id or class name using keyboard shortcuts. Underscores and camelCase do not get detected and the cursor will drift right over them as if it were all one single word.

Try out with mImageCaptureUri.getPath(); By Below Way :

if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {  

            //Get your Image Path
            String Path=mImageCaptureUri.getPath();

            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
            knop.setVisibility(Button.VISIBLE);
            System.out.println(mImageCaptureUri);
        }  

I found this answer very effective but not very easy to read for me.

To make it more clear you can invert the key and the value of a dictionary. This is make the keys values and the values keys, as seen here.

mydict = {'george':16,'amber':19}
res = dict((v,k) for k,v in mydict.iteritems())
print(res[16]) # Prints george

or

mydict = {'george':16,'amber':19}
dict((v,k) for k,v in mydict.iteritems())[16]

which is essentially the same that this other answer.

If you want to add an empty folder you can add a '.keep' file in your folder.

This is because git does not care about folders.

The best way is to create a variable of type Worksheet, assign the worksheet and use it every time the VBA would implicitly use the ActiveSheet.

This will help you avoid bugs that will eventually show up when your program grows in size.

For example something like Range("A1:C10").Sort Key1:=Range("A2") is good when the macro works only on one sheet. But you will eventually expand your macro to work with several sheets, find out that this doesn't work, adjust it to ShTest1.Range("A1:C10").Sort Key1:=Range("A2")... and find out that it still doesn't work.

Here is the correct way:

Dim ShTest1 As Worksheet
Set ShTest1 = Sheets("Test1")
ShTest1.Range("A1:C10").Sort Key1:=ShTest1.Range("A2")

Unexpected '='

This can be caused by having invalid characters in a variable name. Variables names must follow these rules:

Variable names follow the same rules as other labels in PHP. A valid variable name starts with a letter or underscore, followed by any number of letters, numbers, or underscores. As a regular expression, it would be expressed thus: '[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*'

>>> import os
>>> os.system('cd c:\mydir')

In fact, os.system() can execute any command that windows command prompt can execute, not just change dir.

Always try to do an associative fetch, that way you can easy get what you want in multiple case result

Here's an example

$result = $mysqli->query("SELECT COUNT(*) AS cityCount FROM myCity")
$row = $result->fetch_assoc();
echo $row['cityCount']." rows in table myCity.";

jQuery.trim(" hello, how are you? ");

:)

try something like this

<script type="text/javascript">
function PopUp(hideOrshow) {
    if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
    else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
    setTimeout(function () {
        PopUp('show');
    }, 5000);
}
</script>

and your html

<div id="ac-wrapper" style='display:none'>
    <div id="popup">
        <center>
             <h2>Popup Content Here</h2>    
            <input type="submit" name="submit" value="Submit" onClick="PopUp('hide')" />
        </center>
    </div>
</div>

Demo JsFiddle

You have the answer right there in your question. You cannot directly pass wildcard when using IN. However, you can use a sub-query.

Try this:

select *
from jobdetails
where job_no in (
select job_no
from jobdetails
where job_no like '0711%' or job_no like '0712%')
)

I know that this looks crazy, as you can just stick to using OR in your WHERE clause. why the subquery? How ever, the subquery approach will be useful when you have to match details from a different source.

  cout<<*min_element(v.begin(),v.end());

Other answers show how to use pip with both 2.X and 3.X Python, but does not show how to handle the case of multiple Python distributions (eg. original Python and Anaconda Python).

I have a total of 3 Python versions: original Python 2.7 and Python 3.5 and Anaconda Python 3.5.

Here is how I install a package into:

1. Original Python 3.5:

   /usr/bin/python3 -m pip install python-daemon
   

2. Original Python 2.7:

   /usr/bin/python -m pip install python-daemon
   

3. Anaconda Python 3.5:

   python3 -m pip install python-daemon
   

   or

   pip3 install python-daemon
   

   Simpler, as Anaconda overrides original Python binaries in user environment.

   Of course, installing in anaconda should be done with conda command, this is just an example.

Also, make sure that pip is installed for that specific python.You might need to manually install pip. This works in Ubuntu 16.04:

sudo apt-get install python-pip 

or

sudo apt-get install python3-pip

In addition to adding @Transactional on @Test method, you also need to add @Rollback(false)

I think what you want is a different content mode. Try using UIViewContentModeScaleToFill. This will scale the content to fit the size of ur UIImageView by changing the aspect ratio of the content if necessary.

Have a look to the content mode section on the official doc to get a better idea of the different content mode available (it is illustrated with images).

I ended up following @vicenteherrera's approach, with some tweaks (that are possibly bootstrap 3 specific).

Basically; we can't break trs, or tds because they're not block-level elements. So we embed divs into each, and apply our page-break-* rules against the div. Secondly; we add some padding to the top of each of these divs, to compensate for any styling artifacts.

<style>
    @media print {
        /* avoid cutting tr's in half */
        th div, td div {
            margin-top:-8px;
            padding-top:8px;
            page-break-inside:avoid;
        }
    }
</style>
<script>
    $(document).ready(function(){
        // Wrap each tr and td's content within a div
        // (todo: add logic so we only do this when printing)
        $("table tbody th, table tbody td").wrapInner("<div></div>");
    })
</script>

The margin and padding adjustments were necessary to offset some kind of jitter that was being introduced (by my guess - from bootstrap). I'm not sure that I'm presenting any new solution from the other answers to this question, but I figure maybe this will help someone.

This would restore focus to the previous application and exit the script if the answer was empty.

a=$(osascript -e 'try
tell app "SystemUIServer"
set answer to text returned of (display dialog "" default answer "")
end
end
activate app (path to frontmost application as text)
answer' | tr '\r' ' ')
[[ -z "$a" ]] && exit

If you told System Events to display the dialog, there would be a small delay if it wasn't running before.

For documentation about display dialog, open the dictionary of Standard Additions in AppleScript Editor or see the AppleScript Language Guide.

rgl is great, but takes a bit of experimentation to get the axes right.

If you have a lot of points, why not take a random sample from them, and then plot the resulting surface. You can add several surfaces all based on samples from the same data to see if the process of sampling is horribly affecting your data.

So, here is a pretty horrible function but it does what I think you want it to do (but without the sampling). Given a matrix (x, y, z) where z is the heights it will plot both the points and also a surface. Limitations are that there can only be one z for each (x,y) pair. So planes which loop back over themselves will cause problems.

The plot_points = T will plot the individual points from which the surface is made - this is useful to check that the surface and the points actually meet up. The plot_contour = T will plot a 2d contour plot below the 3d visualization. Set colour to rainbow to give pretty colours, anything else will set it to grey, but then you can alter the function to give a custom palette. This does the trick for me anyway, but I'm sure that it can be tidied up and optimized. The verbose = T prints out a lot of output which I use to debug the function as and when it breaks.

plot_rgl_model_a <- function(fdata, plot_contour = T, plot_points = T, 
                             verbose = F, colour = "rainbow", smoother = F){
  ## takes a model in long form, in the format
  ## 1st column x
  ## 2nd is y,
  ## 3rd is z (height)
  ## and draws an rgl model

  ## includes a contour plot below and plots the points in blue
  ## if these are set to TRUE

  # note that x has to be ascending, followed by y
  if (verbose) print(head(fdata))

  fdata <- fdata[order(fdata[, 1], fdata[, 2]), ]
  if (verbose) print(head(fdata))

So my approach would be to, try to do it with all your data (I easily plot surfaces generated from ~15k points). If that doesn't work, take several smaller samples and plot them all at once using these functions.

Adding on to what ADNow said. On the Macintosh:

1. Right click on IntelliJ IDEA 12
2. Click on the Show Package Contents menu option
3. Open the bin folder
4. Open idea.properties

5. Add the line:

   auto.show.quick.doc=true

If your digit is, say, '5', in ASCII it is represented as the binary number 0011 0101 (53). Every digit has the highest four bits 0011 and the lowest 4 bits represent the digit in bcd. So you just do

char cdig = '5';
int dig = cdig & 0xf; // dig contains the number 5

to get the lowest 4 bits, or, what its same, the digit. In asm, it uses and operation instead of sub(as in the other answers).

Okay you must try this guys it works for me:

1. Open SDK Manager and Install SDK build tools 22.0.1
2. Sync gradle That'all

The most common complaint/question I've seen wrt PyInstaller is "my code can't find a data file which I definitely included in the bundle, where is it?", and it isn't easy to see what/where your code is searching because the extracted code is in a temp location and is removed when it exits. Add this bit of code to see what's included in your onefile and where it is, using @Jonathon Reinhart's resource_path()

for root, dirs, files in os.walk(resource_path("")):
    print(root)
    for file in files:
        print( "  ",file)

Slightly shorter than what was mentioned by Carl Smotricz:

!string.trim().isEmpty();

Please refer the link from JQuery

http://api.jquery.com/keypress/

It says

The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser.

That means you can not use keypress in case of arrows.

Another pure Bash solution:

while IFS=':' read a b ; do
  echo "$a"
done < "$infile" > "$outfile"

string formatted = date.ToString("dd-MM-yyyy");

will do it.

Here is a good reference for different formats.

I am using in those cases you are referring switch(). It looks like a control statement but actually, it is a function. The expression is evaluated and based on this value, the corresponding item in the list is returned.

switch works in two distinct ways depending whether the first argument evaluates to a character string or a number.

What follows is a simple string example which solves your problem to collapse old categories to new ones.

For the character-string form, have a single unnamed argument as the default after the named values.

newCat <- switch(EXPR = category,
       cat1   = catX,
       cat2   = catX,
       cat3   = catY,
       cat4   = catY,
       cat5   = catZ,
       cat6   = catZ,
       "not available")

I think best approach is xian's answer.

but...

# Nested for loop

This approach is dirty, but can solve at all version.

so, I often use it in macro functions.

for(int _int=0, /* make local variable */ \
    loopOnce=true; loopOnce==true; loopOnce=false)

    for(char _char=0; _char<3; _char++)
    {
        // do anything with
        // _int, _char
    }

Additional 1.

It can also be used to declare local variables and initialize global variables.

float globalFloat;

for(int localInt=0, /* decalre local variable */ \
    _=1;_;_=0)

    for(globalFloat=2.f; localInt<3; localInt++) /* initialize global variable */
    {
        // do.
    }

Additional 2.

Good example : with macro function.

(If best approach can't be used because it is a for-loop-macro)

#define for_two_decl(_decl_1, _decl_2, cond, incr) \
for(_decl_1, _=1;_;_=0)\
    for(_decl_2; (cond); (incr))


    for_two_decl(int i=0, char c=0, i<3, i++)
    {
        // your body with
        // i, c
    }

# If-statement trick

if (A* a=nullptr);
else
    for(...) // a is visible

If you want initialize to 0 or nullptr, you can use this trick.

but I don't recommend this because of hard reading.

and it seems like bug.

You can pass an array as the first AutoFilter argument and use the xlFilterValues operator.

This will display PDF, DOC and DOCX filetypes.

Criteria1:=Array(".pdf", ".doc", ".docx"), Operator:=xlFilterValues

I had the same problem and non of the given answers worked. But I found a git commit with a fix that did work for me:

sup {
  font-size: 0.8em;
  line-height: 0;
  position: relative;
  vertical-align: baseline;
  top: -0.5em;
}

This is the query I normally use,

select s.sid
      ,s.serial#
      ,s.username
      ,s.machine
      ,s.status
      ,s.lockwait
      ,t.used_ublk
      ,t.used_urec
      ,t.start_time
from v$transaction t
inner join v$session s on t.addr = s.taddr;

Here is a slight improvement on the this answer above taking care of both .xlsx and .xls files in the same routine, in case it helps someone!

I also add a line to choose to save with the active sheet name instead of the workbook, which is most practical for me often:

Sub ExportAsCSV()

    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook

    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy

    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
    End With

    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, InStrRev(CurrentWB.Name, ".") - 1) & ".csv"
    'Optionally, comment previous line and uncomment next one to save as the current sheet name
    'MyFileName = CurrentWB.Path & "\" & CurrentWB.ActiveSheet.Name & ".csv"


    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

There you go....this is the function to replace every occurance of char x with char y within character string str

char *zStrrep(char *str, char x, char y){
    char *tmp=str;
    while(*tmp)
        if(*tmp == x)
            *tmp++ = y; /* assign first, then incement */
        else
            *tmp++;

    *tmp='\0';
    return str;
}

An example usage could be

  Exmaple Usage
        char s[]="this is a trial string to test the function.";
        char x=' ', y='_';
        printf("%s\n",zStrrep(s,x,y));

  Example Output
        this_is_a_trial_string_to_test_the_function.

The function is from a string library I maintain on Github, you are more than welcome to have a look at other available functions or even contribute to the code :)

https://github.com/fnoyanisi/zString

EDIT: @siride is right, the function above replaces chars only. Just wrote this one, which replaces character strings.

#include <stdio.h>
#include <stdlib.h>

/* replace every occurance of string x with string y */
char *zstring_replace_str(char *str, const char *x, const char *y){
    char *tmp_str = str, *tmp_x = x, *dummy_ptr = tmp_x, *tmp_y = y;
    int len_str=0, len_y=0, len_x=0;

    /* string length */
    for(; *tmp_y; ++len_y, ++tmp_y)
        ;

    for(; *tmp_str; ++len_str, ++tmp_str)
        ;

    for(; *tmp_x; ++len_x, ++tmp_x)
        ;

    /* Bounds check */
    if (len_y >= len_str)
        return str;

    /* reset tmp pointers */
    tmp_y = y;
    tmp_x = x;

    for (tmp_str = str ; *tmp_str; ++tmp_str)
        if(*tmp_str == *tmp_x) {
            /* save tmp_str */
            for (dummy_ptr=tmp_str; *dummy_ptr == *tmp_x; ++tmp_x, ++dummy_ptr)
                if (*(tmp_x+1) == '\0' && ((dummy_ptr-str+len_y) < len_str)){
                /* Reached end of x, we got something to replace then!
                * Copy y only if there is enough room for it
                */
                    for(tmp_y=y; *tmp_y; ++tmp_y, ++tmp_str)
                        *tmp_str = *tmp_y;
            }
        /* reset tmp_x */
        tmp_x = x;
        }

    return str;
}

    printf("%s\n\n",s);
    printf("%s\n",zstring_replace_str(s,"ree","XYZ"));
    return 0;

If you're not using Homebrew, this is what I just did on MAC OS X Lion (10.7.5):

1. Get the latest version of the ZSH sourcecode

2. Untar the download into its own directory then install: ./configure && make && make test && sudo make install

3. This installs the the zsh binary at /usr/local/bin/zsh.

4. You can now use the shell by loading up a new terminal and executing the binary directly, but you'll want to make it your default shell...

5. To make it your default shell you must first edit /etc/shells and add the new path. Then you can either run chsh -s /usr/local/bin/zsh or go to System Preferences > Users & Groups > right click your user > Advanced Options... > and then change "Login shell".

6. Load up a terminal and check you're now in the correct version with echo $ZSH_VERSION. (I wasn't at first, and it took me a while to figure out I'd configured iTerm to use a specific shell instead of the system default).

You want to use the array_key_exists function.

Check whether .git/config contains

[remote "origin"]
    url = …
    fetch = +refs/heads/master:refs/remotes/origin/master

If so, change it to say

[remote "origin"]
    url = …
    fetch = +refs/heads/*:refs/remotes/origin/*

Then you should be able to use it:

$ git fetch
remote: Counting objects: …
remote: Compressing objects: ..
Unpacking objects: …
remote: …
From …
 * [new branch]            branchname -> origin/branchname
$ git checkout branchname
Branch branchname set up to track remote branch branchname from origin.
Switched to a new branch 'branchname'

Use SAJAX or switch to JavaScript

Sajax is an open source tool to make programming websites using the Ajax framework — also known as XMLHTTPRequest or remote scripting — as easy as possible. Sajax makes it easy to call PHP, Perl or Python functions from your webpages via JavaScript without performing a browser refresh.

You can do it calling setRowSelectionInterval :

table.setRowSelectionInterval(0, 0);

to select the first row.

The user @manoj has provided the correct answer to the question. From Kibana host, a request to http://localhost:9200/ will not be answered, unless ElasticSearch is also running on the same node. Kibana listens on port 5601 not 9200.

In most cases, except for DEV, ElasticSearch will not be on the same node as Kibana, for a number of reasons. Therefore, to get information about your ElasticSearch from Kibana, you should select the "Dev Tools" tab on the left and in the console issue the command: GET /

You can use the entry set and iterate over the entries which allows you to access both, key and value, directly.

for (Entry<String, ArrayList<String>> entry : test1.entrySet() {
     System.out.println(entry.getKey() + "/" + entry.getValue());
}

I tried this but get only returns string

Why do you think so? The method get returns the type E for which the generic type parameter was chosen, in your case ArrayList<String>.

Here is an example of my custom Filter class:

package com.dawson.controller.filter;

import org.springframework.stereotype.Component;
import org.springframework.web.filter.GenericFilterBean;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;


@Component
public class DawsonApiFilter extends GenericFilterBean {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest req = (HttpServletRequest) request;
        if (req.getHeader("x-dawson-nonce") == null || req.getHeader("x-dawson-signature") == null) {
            HttpServletResponse httpResponse = (HttpServletResponse) response;
            httpResponse.setContentType("application/json");
            httpResponse.sendError(HttpServletResponse.SC_BAD_REQUEST, "Required headers not specified in the request");
            return;
        }
        chain.doFilter(request, response);
    }
}

And I added it to the Spring boot configuration by adding it to Configuration class as follows:

package com.dawson.configuration;

import com.fasterxml.jackson.datatype.hibernate5.Hibernate5Module;
import com.dawson.controller.filter.DawsonApiFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

@SpringBootApplication
public class ApplicationConfiguration {
    @Bean
    public FilterRegistrationBean dawsonApiFilter() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new DawsonApiFilter());
// In case you want the filter to apply to specific URL patterns only
        registration.addUrlPatterns("/dawson/*");
        return registration;
    }
}

I was asking the same question just now after a quick google I found that There is a pair class in .NET except its in the System.Web.UI ^ ~ ^ (http://msdn.microsoft.com/en-us/library/system.web.ui.pair.aspx) goodness knows why they put it there instead of the collections framework

If you change your program slightly:

#include <iostream>
using namespace std;
int main()
{
    int array[2];
    INT NOTHING;
    CHAR FOO[4];
    STRCPY(FOO, "BAR");
    array[0] = 1;
    array[1] = 2;
    array[3] = 3;
    array[4] = 4;
    cout << array[3] << endl;
    cout << array[4] << endl;
    COUT << FOO << ENDL;
    return 0;
}

(Changes in capitals -- put those in lower case if you're going to try this.)

You will see that the variable foo has been trashed. Your code will store values into the nonexistent array[3] and array[4], and be able to properly retrieve them, but the actual storage used will be from foo.

So you can "get away" with exceeding the bounds of the array in your original example, but at the cost of causing damage elsewhere -- damage which may prove to be very hard to diagnose.

As to why there is no automatic bounds checking -- a correctly written program does not need it. Once that has been done, there is no reason to do run-time bounds checking and doing so would just slow down the program. Best to get that all figured out during design and coding.

C++ is based on C, which was designed to be as close to assembly language as possible.

As suggested by A Star, I always use something along the lines of:

DATE(NOW()) - INTERVAL 1 MONTH

Similarly you can do:

NOW() + INTERVAL 5 MINUTE
"2013-01-01 00:00:00" + INTERVAL 10 DAY

and so on. Much easier than typing DATE_ADD or DATE_SUB all the time :)!

This helped me understand / streamline, only what I needed to animate:

// SCSS - Multiple Animation: Properties | durations | etc.
// on hover, animate div (width/opacity) - from: {0px, 0} to: {100vw, 1}

.base {
  max-width: 0vw;
  opacity: 0;

  transition-property: max-width, opacity; // relative order
  transition-duration: 2s, 4s; // effects relatively ordered animation properties
  transition-delay: 6s; // effects delay of all animation properties
  animation-timing-function: ease;

  &:hover {
    max-width: 100vw;
    opacity: 1;

    transition-duration: 5s; // effects duration of all aniomation properties
    transition-delay: 2s, 7s; // effects relatively ordered animation properties
  }
}

~ This applies for all transition properties (duration, transition-timing-function, etc.) within the '.base' class

Microsoft explains it in the KB305703 article on How to start the default Internet browser programmatically by using Visual C#.

Don't forget to check the Troubleshooting section.

As stated before, the image is treated as text, so the bottom is to accommodate for those pesky: "p,q,y,g,j"; the easiest solution is to assign the img display:block; in your css.

But this does inhibit the standard image behavior of flowing with the text. To keep that behavior and eliminate the space. I recommend wrapping the image with something like this.

<style>
    .imageHolder
    {
        display: inline-block;
    }
    img.noSpace
    {
        display: block;
    }
</style>
<div class="imageHolder"><img src="myimg.png" class="noSpace"/></div>

https://router.vuejs.org/en/api/router-link.html add attribute active-class="active" eg:

<ul class="nav navbar-nav">
    <router-link tag="li" active-class="active" to="/" exact><a>Home</a></router-link>
    <router-link tag="li" active-class="active" to="/about"><a>About</a></router-link>
    <router-link tag="li" active-class="active" to="/permission-list"><a>Permisison</a></router-link>
</ul>

You really don't need jQuery for that:

var doc = document.getElementById('iframe').contentWindow.document;
doc.open();
doc.write('Test');

If you absolutely have to use jQuery, you should use contents():

var $iframe = $('#iframe');
$iframe.ready(function() {
    $iframe.contents().find("body").append('Test');
});

jsFiddle Demo

Please don't forget that if you're using jQuery, you'll need to hook into the DOMReady function as follows:

$(function() {  
    var $iframe = $('#iframe');
    $iframe.ready(function() {
        $iframe.contents().find("body").append('Test');
    });
});

The short answer is, you have to loop.

What's the fastest way to copy the values and keys from one dictionary into another in C#?

Scroll down on this link and view the section, it gives you a comparative example as seen below:

<?php
/** Fetches the value of $_GET['user'] and returns 'nobody' if it does not exist. **/
$username = $_GET['user'] ?? 'nobody';
/** This is equivalent to: **/
$username = isset($_GET['user']) ? $_GET['user'] : 'nobody';

/** Coalescing can be chained: this will return the first defined value out of $_GET['user'], $_POST['user'], and 'nobody'. **/
$username = $_GET['user'] ?? $_POST['user'] ?? 'nobody';
?>

However, it is not advised to chain the operators as it makes it harder to understand the code when reading it later on.

The null coalescing operator (??) has been added as syntactic sugar for the common case of needing to use a ternary in conjunction with isset(). It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.

Essentially, using the coalescing operator will make it auto check for null unlike the ternary operator.

What you want to do is fetch the value from the input and assign it to a new Date instance.

let date = document.getElementById('dateInput');

let formattedDate = new Date(date.value);

console.log(formattedDate);

Thank you all for this information. This is incredibly annoying.

Add this to your code and you'll never have to think about it again:

var app = express();

app.all("*", function (req, res, next) {  // runs on ALL requests
    req.fullUrl = req.protocol + '://' + req.get('host') + req.originalUrl
        next()
})

You can do or set other things there as well, such as log to console.

The document suggests that it takes the @color/accent by default. But we can override it on code by using

fab.setBackgroundTintList(ColorStateList)

Also remember,

The minimum API version to use this library is 15 so you need to update it! if you dont want to do it then you need to define a custom drawable and decorate it!

In order to replace text using regular expression use the re.sub function:

sub(pattern, repl, string[, count, flags])

It will replace non-everlaping instances of pattern by the text passed as string. If you need to analyze the match to extract information about specific group captures, for instance, you can pass a function to the string argument. more info here.

Examples

>>> import re
>>> re.sub(r'a', 'b', 'banana')
'bbnbnb'

>>> re.sub(r'/\d+', '/{id}', '/andre/23/abobora/43435')
'/andre/{id}/abobora/{id}'

TL/DR:

fetch now supports a signal parameter as of 20 September 2017, but not all browsers seem support this at the moment.

2020 UPDATE: Most major browsers (Edge, Firefox, Chrome, Safari, Opera, and a few others) support the feature, which has become part of the DOM living standard. (as of 5 March 2020)

This is a change we will be seeing very soon though, and so you should be able to cancel a request by using an AbortControllers AbortSignal.

Long Version

How to:

The way it works is this:

Step 1: You create an AbortController (For now I just used this)

const controller = new AbortController()

Step 2: You get the AbortControllers signal like this:

const signal = controller.signal

Step 3: You pass the signal to fetch like so:

fetch(urlToFetch, {
    method: 'get',
    signal: signal, // <------ This is our AbortSignal
})

Step 4: Just abort whenever you need to:

controller.abort();

Here's an example of how it would work (works on Firefox 57+):

    // Create an instance._x000D_
    const controller = new AbortController()_x000D_
    const signal = controller.signal_x000D_

    })_x000D_
    */_x000D_
_x000D_
_x000D_

_x000D_

                method: 'get',_x000D_
                signal: signal,_x000D_
            })_x000D_
            .then(function(response) {_x000D_
                console.log(`Fetch complete. (Not aborted)`);_x000D_
            }).catch(function(err) {_x000D_
                console.error(` Err: ${err}`);_x000D_
            });_x000D_
    }_x000D_
_x000D_
_x000D_
    function abortFetching() {_x000D_
        console.log('Now aborting');_x000D_
        // Abort._x000D_
        controller.abort()_x000D_
    }_x000D_
_x000D_
</script>_x000D_

As detailed in the jTDS Frequenlty Asked Questions, the URL format for jTDS is:

jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]

So, to connect to a database called "Blog" hosted by a MS SQL Server running on MYPC, you may end up with something like this:

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS;user=sa;password=s3cr3t

Or, if you prefer to use getConnection(url, "sa", "s3cr3t"):

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS

EDIT: Regarding your Connection refused error, double check that you're running SQL Server on port 1433, that the service is running and that you don't have a firewall blocking incoming connections.

You just need to put "group(1)" instead of "group()" in the following line and the return will be the one you expected:

System.out.println("I found the text: " + matcher.group(**1**).toString());
