In iOS 10, and on newer iPhones, you can also use haptic API. This haptic feedback is softer than the AudioToolbox API.

For your GAME OVER scenario, a heavy UI impact feedback should be suitable.

UIImpactFeedbackGenerator(style: .heavy).impactOccurred()

You could use the other haptic feedback styles.

Try:

import android.os.Vibrator;
...
Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
// Vibrate for 500 milliseconds
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    v.vibrate(VibrationEffect.createOneShot(500, VibrationEffect.DEFAULT_AMPLITUDE));
} else {
    //deprecated in API 26 
    v.vibrate(500);
}

Note:

Don't forget to include permission in AndroidManifest.xml file:

<uses-permission android:name="android.permission.VIBRATE"/>

$("#year").datepicker( {
    format: "yyyy",
    viewMode: "years", 
    minViewMode: "years"
}).on('changeDate', function(e){
    $(this).datepicker('hide');
});

if you use route and pass paramater use this code in your blade file

{{dd(request()->route()->parameters)}}

The fix was at the accepted answer. Yet if someone wants to know why it worked and why the implementation in the SO question didn't work,

First, functions are first class objects in JavaScript. That means they are treated like any other variable. Function can be passed as an argument to other functions, can be returned by another function and can be assigned as a value to a variable. Read more here.

So we use that variable to invoke the function by adding parentheses () at the end.

One thing, If you have a function that returns a funtion and you just need to call that returned function, you can just have double paranthesis when you call the outer function ()().

Add this code inside your input tag

<?php if ($tag_1 == 'yes') echo "checked='checked'"; ?>

You can use istringstream.

string s = "10";

// create an input stream with your string.
istringstream is(str);

int i;
// use is like an input stream
is >> i;

You can override any built-in function by just re-declaring it.

parseFloat = function(a){
  alert(a)
};

Now parseFloat(3) will alert 3.

The trick is to create subclasses of ViewHolder and then cast them.

public class GroupViewHolder extends RecyclerView.ViewHolder {
    TextView mTitle;
    TextView mContent;
    public GroupViewHolder(View itemView) {
        super (itemView);
        // init views...
    }
}

public class ImageViewHolder extends RecyclerView.ViewHolder {
    ImageView mImage;
    public ImageViewHolder(View itemView) {
        super (itemView);
        // init views...
    }
}

private static final int TYPE_IMAGE = 1;
private static final int TYPE_GROUP = 2;  

And then, at runtime do something like this:

@Override
public int getItemViewType(int position) {
    // here your custom logic to choose the view type
    return position == 0 ? TYPE_IMAGE : TYPE_GROUP;
}

@Override
public void onBindViewHolder (ViewHolder viewHolder, int i) {

    switch (viewHolder.getItemViewType()) {

        case TYPE_IMAGE:
            ImageViewHolder imageViewHolder = (ImageViewHolder) viewHolder;
            imageViewHolder.mImage.setImageResource(...);
            break;

        case TYPE_GROUP:
            GroupViewHolder groupViewHolder = (GroupViewHolder) viewHolder;
            groupViewHolder.mContent.setText(...)
            groupViewHolder.mTitle.setText(...);
            break;
    }
}

Hope it helps.

You can use body-parser, the Node.js body parsing middleware.

First load body-parser

$ npm install body-parser --save

Some example code

var express = require('express')
var bodyParser = require('body-parser')

var app = express()

app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())


app.use(function (req, res) {
  var post_data = req.body;
  console.log(post_data);
})

If this is what you want only HTML and CSS solution

Here's the HTML

Let me know if this is what you need. Or some thing is missing. I went through the other answers and found that jquery has been used . I took it on assumption that you need css solution . If I am missing any more point please mention :)

Declaration

A prototype for a function which takes a function parameter looks like the following:

void func ( void (*f)(int) );

This states that the parameter f will be a pointer to a function which has a void return type and which takes a single int parameter. The following function (print) is an example of a function which could be passed to func as a parameter because it is the proper type:

void print ( int x ) {
  printf("%d\n", x);
}

Function Call

When calling a function with a function parameter, the value passed must be a pointer to a function. Use the function's name (without parentheses) for this:

func(print);

would call func, passing the print function to it.

Function Body

As with any parameter, func can now use the parameter's name in the function body to access the value of the parameter. Let's say that func will apply the function it is passed to the numbers 0-4. Consider, first, what the loop would look like to call print directly:

for ( int ctr = 0 ; ctr < 5 ; ctr++ ) {
  print(ctr);
}

Since func's parameter declaration says that f is the name for a pointer to the desired function, we recall first that if f is a pointer then *f is the thing that f points to (i.e. the function print in this case). As a result, just replace every occurrence of print in the loop above with *f:

void func ( void (*f)(int) ) {
  for ( int ctr = 0 ; ctr < 5 ; ctr++ ) {
    (*f)(ctr);
  }
}

Source

C++03 3.10/1 says: "Every expression is either an lvalue or an rvalue." It's important to remember that lvalueness versus rvalueness is a property of expressions, not of objects.

Lvalues name objects that persist beyond a single expression. For example, obj , *ptr , ptr[index] , and ++x are all lvalues.

Rvalues are temporaries that evaporate at the end of the full-expression in which they live ("at the semicolon"). For example, 1729 , x + y , std::string("meow") , and x++ are all rvalues.

The address-of operator requires that its "operand shall be an lvalue". if we could take the address of one expression, the expression is an lvalue, otherwise it's an rvalue.

 &obj; //  valid
 &12;  //invalid

You can't install Integration Services with it. Express does not support Integration Services. So if you want build say SSIS-packages you'll need at least Standard Edition.

According to The W3C:

This attribute sets the size of the font. Possible values:

• An integer between 1 and 7. This sets the font to some fixed size, whose rendering depends on the user agent. Not all user agents may render all seven sizes.
• A relative increase in font size. The value "+1" means one size larger. The value "-3" means three sizes smaller. All sizes belong to the scale of 1 to 7.

Hence, the conversion you're asking for is not possible. The browser is not required to use specific sizes with specific size attributes.

Also note that use of the font element is discouraged by W3 in favor of style sheets.

grep matches, grep -v does the inverse. If you need to "match A but not B" you usually use pipes:

grep "${PATT}" file | grep -v "${NOTPATT}"

Apparently, gcc doesn't behave like the one described in The C Programming language

It does in general. For your program to run on Windows it needs to end in .exe, "the C Programming language" was not written with Windows programmers in mind. As you've seen, cygwin emulates many, but not all, features of a POSIX environment.

We can also use Kotlin lambda

editText.setOnKeyListener { _, keyCode, keyEvent ->
        if (keyEvent.action == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_ENTER) {
            Log.d("Android view component", "Enter button was pressed")
            return@setOnKeyListener true
        }
        return@setOnKeyListener false
    }

My solution works only if you need retrieve only one column, however for my needs was the best solution found in terms of performance (it use only one single query!):

SELECT SUBSTRING_INDEX(GROUP_CONCAT(column_x ORDER BY column_y),',',1) AS xyz,
   column_z
FROM table_name
GROUP BY column_z;

It use GROUP_CONCAT in order to create an ordered concat list and then I substring to only the first one.

Your "localhost" cannot resolve the name www.google.com, which means your machine doesn't/can't reach a valid dns server.

Try ping google.com on the console of that machine to verify this.

[Employee(name=John, age=25, salary=3000.0, mobile=9922001), 
Employee(name=Ace, age=22, salary=2000.0, mobile=5924001), 
Employee(name=Keith, age=35, salary=4000.0, mobile=3924401)]


public void whenComparing_thenSortedByName() {
Comparator<Employee> employeeNameComparator
  = Comparator.comparing(Employee::getName);

Arrays.sort(employees, employeeNameComparator);

assertTrue(Arrays.equals(employees, sortedEmployeesByName));

}

result

[Employee(name=Ace, age=22, salary=2000.0, mobile=5924001), 
Employee(name=John, age=25, salary=3000.0, mobile=9922001),

You will need to repeat your call to strtol inside your loops where you are asking the user to try again. In fact, if you make the loop a do { ... } while(...); instead of while, you don't get a the same sort of repeat things twice behaviour.

You should also format your code so that it's possible to see where the code is inside a loop and not.

import csv
inf = csv.reader(open('yourfile.csv','r'))
for row in inf:
  print row[1]

you can use WeakMaps for implementing private property in ES6 class and benefits of String propeties and methods in JavaScript language like below:

const _items = new WeakMap();

class Stack {
  constructor() {
    _items.set(this, []);
  }

push(obj) {
  _items.get(this).push(obj);
}

pop() {
  const L = _items.get(this).length;
  if(L===0)
    throw new Error('Stack is empty');
  return _items.get(this).pop();
}

peek() {
  const items = _items.get(this);
  if(items.length === 0)
    throw new Error ('Stack is empty');
  return items[items.length-1];
}

get count() {
  return _items.get(this).length;
}
}

const stack = new Stack();

//now in console:
//stack.push('a')
//stack.push(1)
//stack.count   => 2
//stack.peek()  => 1
//stack.pop()   => 1
//stack.pop()   => "a"
//stack.count   => 0
//stack.pop()   => Error Stack is empty

One simple approach is to check if unicode is a builtin function. If so, you're in Python 2 and your string will be a string. To ensure everything is in unicode one can do:

import builtins

i = 'cats'
if 'unicode' in dir(builtins):     # True in python 2, False in 3
  i = unicode(i)

The purpose of .iteritems() was to use less memory space by yielding one result at a time while looping. I am not sure why Python 3 version does not support iteritems()though it's been proved to be efficient than .items()

If you want to include a code that supports both the PY version 2 and 3,

try:
    iteritems
except NameError:
    iteritems = items

This can help if you deploy your project in some other system and you aren't sure about the PY version.

• The fastest method to normalize a column of flat, one-level dicts, as per the timing analysis performed by Shijith in this answer:
  • df.join(pd.DataFrame(df.pop('Pollutants').values.tolist()))
  • It will not resolve other issues with columns of list or dicts that are addressed below, such as rows with NaN, or nested dicts.

1. pd.json_normalize(df.Pollutants) is significantly faster than df.Pollutants.apply(pd.Series)
   • See the %%timeit below. For 1M rows, .json_normalize is 47 times faster than .apply.
2. Whether reading data from a file, or from an object returned by a database, or API, it may not be clear if the dict column has dict or str type.
   • If the dictionaries in the column are str type, they must be converted back to a dict type, using ast.literal_eval.
3. Use pd.json_normalize to convert the dicts, with keys as headers and values for rows.
   • Has additional parameters (e.g. record_path & meta) for dealing with nested dicts.
4. Use pandas.DataFrame.join to combine the original DataFrame, df, with the columns created using pd.json_normalize
   • If the index isn't integers (as in the example), first use df.reset_index() to get an index of integers, before doing the normalize and join.
5. Finally, use pandas.DataFrame.drop, to remove the unneeded column of dicts

• As a note, if the column has any NaN, they must be filled with an empty dict
  • df.Pollutants = df.Pollutants.fillna({i: {} for i in df.index})
    • If the 'Pollutants' column is strings, use '{}'.
    • Also see How to json_normalize a column with NaNs?.

I think Dan and Nicola have suitable corrected code, however you may not be clear on why the original code didn't work.

What has been called here a "ternary operator" is called a conditional operator in ECMA-262 section 11.12. It has the form:

LogicalORExpression ? AssignmentExpression : AssignmentExpression

The LogicalORExpression is evaluated and the returned value converted to Boolean (just like an expression in an if condition). If it evaluates to true, then the first AssignmentExpression is evaluated and the returned value returned, otherwise the second is evaluated and returned.

The error in the original code is the extra semi-colons that change the attempted conditional operator into a series of statements with syntax errors.

If you still want to go it alone as I did you can link against bfd and avoid using addr2line as I have done here:

Also use 4 spaces for indentation.

I have found similar issue while registering my activeX (OCX) into windows server 2008 R2.To solve this i used http://www.chestysoft.com/dllregsvr/default.asp tool.There is some dependance problem with my ocx so I am getting "The module temp12.dll failed to load. Make sure the binary is stored at the specified path or debut it to check for problems with the binary or dependent .DLL files. The specified module could not be found" error message. When you try to registered your OCX with this tool it will prompt message if the ocx is having dependency or you will get success message.I got message for mfc70.dll and msvcr70.dll dependency.so i paste these dll into system32 folder of C:\windows and its done.After that I register my ocx sucessfully.I used 32 bit version of chestysoft tool (dllregsvr.exe) on windows server 2008 R2 64bit machine.

I seem to remember that Internet Explorer gets confused if the accept-charset encoding doesn't match the encoding specified in the content-type header. In your example, you claim the document is sent as UTF-8, but want form submits in ISO-8859-1. Try matching those and see if that solves your problem.

Based on another question on stackoverflow, I got this code.. This calculates the result in meters, not in miles :)

 public static float distFrom(float lat1, float lng1, float lat2, float lng2) {
    double earthRadius = 6371000; //meters
    double dLat = Math.toRadians(lat2-lat1);
    double dLng = Math.toRadians(lng2-lng1);
    double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
               Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
               Math.sin(dLng/2) * Math.sin(dLng/2);
    double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
    float dist = (float) (earthRadius * c);

    return dist;
    }

https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html also has charts for locating methods and constructors.

Actually I want timestamp based shorter unique identifier, hence tried the below program.

UPDATE: This code will work on single JVM, but we should think on distributed JVM, hence i am thinking two solutions one with DB and another one without DB.

with DB

Company name (shortname 3 chars) ---- Random_Number ---- Key specific redis COUNTER
(3 char) ------------------------------------------------ (2 char) ---------------- (11 char)

without DB

IPADDRESS ---- THREAD_NUMBER ---- INCR_NUMBER ---- epoch milliseconds
(5 chars) ----------------- (2char) ----------------------- (2 char) ----------------- (6 char)

As of October 2016, Google has added a file upload question type in native Google Forms, no Google Apps Script needed. See documentation.

Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.

NB - You need to do this first on a test copy of your table!

When I did it, I found that unless I also included AND n1.id <> n2.id, it deleted every row in the table.

1. If you want to keep the row with the lowest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
   

2. If you want to keep the row with the highest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
   

I used this method in MySQL 5.1

Not sure about other versions.

Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE, please be advised that using INSERT and DISTINCT is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE, it took more than 2 hours and yet didn't complete.

INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
    SELECT DISTINCT cellId,attributeId,entityRowId,value
    FROM tableName;

For GitLab users I've put up a gist on how I migrated from SVN here:

https://gist.github.com/leftclickben/322b7a3042cbe97ed2af

Steps to migrate from SVN to GitLab

Setup

• SVN is hosted at svn.domain.com.au.
• SVN is accessible via http (other protocols should work).
• GitLab is hosted at git.domain.com.au and:
  • A group is created with the namespace dev-team.
  • At least one user account is created, added to the group, and has an SSH key for the account being used for the migration (test using ssh [email protected]).
  • The project favourite-project is created in the dev-team namespace.
• The file users.txt contains the relevant user details, one user per line, of the form username = First Last <[email protected]>, where username is the username given in SVN logs. (See first link in References section for details, in particular answer by user Casey).

Versions

• subversion version 1.6.17 (r1128011)
• git version 1.9.1
• GitLab version 7.2.1 ff1633f
• Ubuntu server 14.04

Commands

bash
git svn clone --stdlayout --no-metadata -A users.txt 
http://svn.domain.com.au/svn/repository/favourite-project
cd favourite-project
git remote add gitlab [email protected]:dev-team/favourite-project.git
git push --set-upstream gitlab master

That's it! Reload the project page in GitLab web UI and you will see all commits and files now listed.

Notes

• If there are unknown users, the git svn clone command will stop, in which case, update users.txt, cd favourite-project and git svn fetch will continue from where it stopped.
• The standard trunk-tags-branches layout for SVN repository is required.
• The SVN URL given to the git svn clone command stops at the level immediately above trunk/, tags/ and branches/.
• The git svn clone command produces a lot of output, including some warnings at the top; I ignored the warnings.

These two lines on their own wasnt working for me:

xlWorkSheet.Columns.ClearFormats();
xlWorkSheet.Rows.ClearFormats();

You can test by hitting ctrl+end in the sheet and seeing which cell is selected.

I found that adding this line after the first two solved the problem in all instances I've encountered:

Excel.Range xlActiveRange = WorkSheet.UsedRange;

More generally.

byte[] buf = new byte[] { 123, 2, 233 };

string s = String.Concat(buf.Select(b => b.ToString("X2")));

You should put vertical-align: middle on the inner element, not the outer element. Set the line-height property on the outer element to match the height of the outer element. Then set display: inline-block and line-height: normal on the inner element. By doing this, the text on the inner element will wrap with a normal line-height. Works in Chrome, Firefox, Safari, and IE 8+

.main {_x000D_
    height: 72px;_x000D_
    line-height:72px;_x000D_
    border: 1px solid black;_x000D_
}_x000D_
.inner {_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
    line-height: normal;_x000D_
}

<div class="main">_x000D_
    <div class="inner">Vertically centered text</div>_x000D_
</div>

Fiddle

You're thinking too DOM, it's a hard as hell habit to break. Vue recommends you approach it data first.

It's kind of hard to tell in your exact situation but I'd probably use a v-for and make an array of finds to push to as I need more.

Here's how I'd set up my instance:

new Vue({
  el: '#app',
  data: {
    finds: []
  },
  methods: {
    addFind: function () {
      this.finds.push({ value: '' });
    }
  }
});

And here's how I'd set up my template:

<div id="app">
  <h1>Finds</h1>
  <div v-for="(find, index) in finds">
    <input v-model="find.value" :key="index">
  </div>
  <button @click="addFind">
    New Find
  </button>
</div>

Although, I'd try to use something besides an index for the key.

Here's a demo of the above: https://jsfiddle.net/crswll/24txy506/9/

There are MANY reasons to use brace initialization, but you should be aware that the initializer_list<> constructor is preferred to the other constructors, the exception being the default-constructor. This leads to problems with constructors and templates where the type T constructor can be either an initializer list or a plain old ctor.

struct Foo {
    Foo() {}

    Foo(std::initializer_list<Foo>) {
        std::cout << "initializer list" << std::endl;
    }

    Foo(const Foo&) {
        std::cout << "copy ctor" << std::endl;
    }
};

int main() {
    Foo a;
    Foo b(a); // copy ctor
    Foo c{a}; // copy ctor (init. list element) + initializer list!!!
}

Assuming you don't encounter such classes there is little reason not to use the intializer list.

To avoid security issues in Gmail, you should generate an app password first from your Gmail settings and you can use this password instead of a real password to send an email even if you use two steps verification.

The simplest way to put a Toolbar transparent is to define a opacity in @colors section, define a TransparentTheme in @styles section and then put these defines in your toolbar.

@colors.xml

<color name="actionbar_opacity">#33000000</color>

@styles.xml

<style name="TransparentToolbar" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:windowActionBarOverlay">true</item>
    <item name="windowActionBarOverlay">true</item>
</style>

@activity_main.xml

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:background="@color/actionbar_opacity"
        app:theme="@style/TransparentToolbar"
        android:layout_height="?attr/actionBarSize"/>

That's the result:

Use example with from the post of Szilágyi Donát.

I use two querys, one to know what roles I have, excluding connect grant:

SELECT * FROM USER_ROLE_PRIVS WHERE GRANTED_ROLE != 'CONNECT'; -- Roles of the actual Oracle Schema

Know I like to find what privileges/roles my schema/user have; examples of my roles ROLE_VIEW_PAYMENTS & ROLE_OPS_CUSTOMERS. But to find the tables/objecst of an specific role I used:

SELECT * FROM ALL_TAB_PRIVS WHERE GRANTEE='ROLE_OPS_CUSTOMERS'; -- Objects granted at role.

The owner schema for this example could be PRD_CUSTOMERS_OWNER (or the role/schema inself).

Maybe another solution for when the project compiles but the XAML error is showing :

1. In solution explore, on the project node that contains the xaml
2. Right-click on the project and choose 'Unload Project'
3. Right-click on the project and choose 'Reload Project' Make sure that your project is still choosen as "startup project". If not :
4. Right-click on the project and choose 'Set as startup project'

No need to rebuild, or close visual studio.

Dijkstra's algorithm applies more to weighted paths and it sounds like the poster was wanting to find all paths, not just the shortest.

For this application, I'd build a graph (your application sounds like it wouldn't need to be directed) and use your favorite search method. It sounds like you want all paths, not just a guess at the shortest one, so use a simple recursive algorithm of your choice.

The only problem with this is if the graph can be cyclic.

With the connections:

• 1, 2
• 1, 3
• 2, 3
• 2, 4

While looking for a path from 1->4, you could have a cycle of 1 -> 2 -> 3 -> 1.

In that case, then I'd keep a stack as traversing the nodes. Here's a list with the steps for that graph and the resulting stack (sorry for the formatting - no table option):

current node (possible next nodes minus where we came from) [stack]

1. 1 (2, 3) [1]
2. 2 (3, 4) [1, 2]
3. 3 (1) [1, 2, 3]
4. 1 (2, 3) [1, 2, 3, 1] //error - duplicate number on the stack - cycle detected
5. 3 () [1, 2, 3] // back-stepped to node three and popped 1 off the stack. No more nodes to explore from here
6. 2 (4) [1, 2] // back-stepped to node 2 and popped 1 off the stack.
7. 4 () [1, 2, 4] // Target node found - record stack for a path. No more nodes to explore from here
8. 2 () [1, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes to explore from here
9. 1 (3) [1] //back-stepped to node 1 and popped 2 off the stack.
10. 3 (2) [1, 3]
11. 2 (1, 4) [1, 3, 2]
12. 1 (2, 3) [1, 3, 2, 1] //error - duplicate number on the stack - cycle detected
13. 2 (4) [1, 3, 2] //back-stepped to node 2 and popped 1 off the stack
14. 4 () [1, 3, 2, 4] Target node found - record stack for a path. No more nodes to explore from here
15. 2 () [1, 3, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes
16. 3 () [1, 3] // back-stepped to node 3 and popped 2 off the stack. No more nodes
17. 1 () [1] // back-stepped to node 1 and popped 3 off the stack. No more nodes
18. Done with 2 recorded paths of [1, 2, 4] and [1, 3, 2, 4]

You can use Location as mentioned here.

Here's my code if the link opened on new tab

navBack() {
    let cur_path = this.location.path();
    this.location.back();
    if (cur_path === this.location.path())
     this.router.navigate(['/default-route']);    
  }

Required imports

import { Router } from '@angular/router';
import { Location } from '@angular/common';

For what it's worth, I found the following syntax to work the best:

SELECT * FROM [LINKED_SERVER]...[TABLE]

I couldn't get the recommendations of others to work, using the database name. Additionally, this data source has no schema.

Since functions in Javascript can be called with any number of arguments, and the document doesn't place any restriction on the onFulfilled() method's arguments besides the below clause, I think that you can pass multiple arguments to the onFulfilled() method as long as the promise's value is the first argument.

2.2.2.1 it must be called after promise is fulfilled, with promise’s value as its first argument.

The property to set is => WindowStyle="None"

<Window x:Class="mdaframework.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            Title="Start" Height="350" Width="525" ResizeMode="NoResize"  WindowStartupLocation="CenterScreen" WindowStyle="None">

It is a new signing mechanism introduced in Android 7.0, with additional features designed to make the APK signature more secure.

It is not mandatory. You should check BOTH of those checkboxes if possible, but if the new V2 signing mechanism gives you problems, you can omit it.

So you can just leave V2 unchecked if you encounter problems, but should have it checked if possible.

UPDATED: This is now mandatory when targeting Android 11.

For system resources only!

Use

Resources.getSystem().getString(android.R.string.cancel)

You can use them everywhere in your application, even in static constants declarations!

You can put an <a> element inside the <div> and set it to display: block and height: 100%.

1. edit your .bash_profile file

   vim .bash_profile

2. commnet

   #export TERM=xterm-256color

3. add this

   export TERMINFO=/usr/share/terminfo

   export TERM=xterm-basic

   to your .bash_profile

4. finally

   run:

   source .bash_profile

I faced this issue as well but in my case, I was in wrong directory. Check the directory you are working

None of the above answers solved it for me.

I cant even find the 'libraries' folder in my xampp - ubuntu also.

So, I simply restarted using the following commands:

sudo service apache2 restart

and

sudo service mysql restart

• Just restarted apache and mysql. Logged in phpmyadmin again and it worked as usual.

Thanks me..!!

Here's a TypeScript implementation of https://stackoverflow.com/a/21323330/916734. It also dries things up with functions, and allows for a optional digit offset.

export function round(rawValue: number | string, precision = 0, fractionDigitOffset = 0): number | string {
  const value = Number(rawValue);
  if (isNaN(value)) return rawValue;

  precision = Number(precision);
  if (precision % 1 !== 0) return NaN;

  let [ stringValue, exponent ] = scientificNotationToParts(value);

  let shiftExponent = exponentForPrecision(exponent, precision, Shift.Right);
  const enlargedValue = toScientificNotation(stringValue, shiftExponent);
  const roundedValue = Math.round(enlargedValue);

  [ stringValue, exponent ] = scientificNotationToParts(roundedValue);
  const precisionWithOffset = precision + fractionDigitOffset;
  shiftExponent = exponentForPrecision(exponent, precisionWithOffset, Shift.Left);

  return toScientificNotation(stringValue, shiftExponent);
}

enum Shift {
  Left = -1,
  Right = 1,
}

function scientificNotationToParts(value: number): Array<string> {
  const [ stringValue, exponent ] = value.toString().split('e');
  return [ stringValue, exponent ];
}

function exponentForPrecision(exponent: string, precision: number, shift: Shift): number {
  precision = shift * precision;
  return exponent ? (Number(exponent) + precision) : precision;
}

function toScientificNotation(value: string, exponent: number): number {
  return Number(`${value}e${exponent}`);
}

OK I found it.

=LARGE($E$4:$E$9;A12)

=large(array, k)

Array Required. The array or range of data for which you want to determine the k-th largest value.

K Required. The position (from the largest) in the array or cell range of data to return.

    BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();

while ((sResponse = reader.readLine()) != null) {
    s = s.append(sResponse);
}
Gson gson = new Gson();

JSONObject jsonObject = new JSONObject(s.toString());
String link = jsonObject.getString("Result");

This is really a tricky thing to have a sticky header on your table. I had same requirement but with asp:GridView and then I found it really thought to have sticky header on gridview. There are many solutions available and it took me 3 days trying all the solution but none of them could satisfy.

The main issue that I faced with most of these solutions was the alignment problem. When you try to make the header floating, somehow the alignment of header cells and body cells get off track.

With some solutions, I also got issue of getting header overlapped to first few rows of body, which cause body rows getting hidden behind the floating header.

So now I had to implement my own logic to achieve this, though I also not consider this as perfect solution but this could also be helpful for someone,

Below is the sample table.

<div class="table-holder">
        <table id="MyTable" cellpadding="4" cellspacing="0" border="1px" class="customerTable">
            <thead>
                <tr><th>ID</th><th>First Name</th><th>Last Name</th><th>DOB</th><th>Place</th></tr>
            </thead>
            <tbody>
                <tr><td>1</td><td>Customer1</td><td>LastName</td><td>1-1-1</td><td>SUN</td></tr>
                <tr><td>2</td><td>Customer2</td><td>LastName</td><td>2-2-2</td><td>Earth</td></tr>
                <tr><td>3</td><td>Customer3</td><td>LastName</td><td>3-3-3</td><td>Mars</td></tr>
                <tr><td>4</td><td>Customer4</td><td>LastName</td><td>4-4-4</td><td>Venus</td></tr>
                <tr><td>5</td><td>Customer5</td><td>LastName</td><td>5-5-5</td><td>Saturn</td></tr>
                <tr><td>6</td><td>Customer6</td><td>LastName</td><td>6-6-6</td><td>Jupitor</td></tr>
                <tr><td>7</td><td>Customer7</td><td>LastName</td><td>7-7-7</td><td>Mercury</td></tr>
                <tr><td>8</td><td>Customer8</td><td>LastName</td><td>8-8-8</td><td>Moon</td></tr>
                <tr><td>9</td><td>Customer9</td><td>LastName</td><td>9-9-9</td><td>Uranus</td></tr>
                <tr><td>10</td><td>Customer10</td><td>LastName</td><td>10-10-10</td><td>Neptune</td></tr>
            </tbody>
        </table>
    </div>

Note: The table is wrapped into a DIV with class attribute equal to 'table-holder'.

Below is the JQuery script that I added in my html page header.

<script src="../Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="../Scripts/jquery-ui.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        //create var for table holder
        var originalTableHolder = $(".table-holder");
        // set the table holder's with
        originalTableHolder.width($('table', originalTableHolder).width() + 17);
        // Create a clone of table holder DIV
        var clonedtableHolder = originalTableHolder.clone();

        // Calculate height of all header rows.
        var headerHeight = 0;
        $('thead', originalTableHolder).each(function (index, element) {
            headerHeight = headerHeight + $(element).height();
        });

        // Set the position of cloned table so that cloned table overlapped the original
        clonedtableHolder.css('position', 'relative');
        clonedtableHolder.css('top', headerHeight + 'px');

        // Set the height of cloned header equal to header height only so that body is not visible of cloned header
        clonedtableHolder.height(headerHeight);
        clonedtableHolder.css('overflow', 'hidden');

        // reset the ID attribute of each element in cloned table
        $('*', clonedtableHolder).each(function (index, element) {
            if ($(element).attr('id')) {
                $(element).attr('id', $(element).attr('id') + '_Cloned');
            }
        });

        originalTableHolder.css('border-bottom', '1px solid #aaa');

        // Place the cloned table holder before original one
        originalTableHolder.before(clonedtableHolder);
    });
</script>

and at last below is the CSS class for bit of coloring purpose.

.table-holder
{
    height:200px;
    overflow:auto;
    border-width:0px;    
}

.customerTable thead
{
    background: #4b6c9e;        
    color:White;
}

So the whole idea of this logic is to place the table into a table holder div and create clone of that holder at client side when page loaded. Now hide the body of table inside clone holder and position the remaining header part over to original header.

Same solution also works for asp:gridview, you need to add two more steps to achieve this in gridview,

1. In OnPrerender event of gridview object in your web page, set the table section of header row equal to TableHeader.

   if (this.HeaderRow != null)
   {
       this.HeaderRow.TableSection = TableRowSection.TableHeader;
   }
   

2. And wrap your grid into <div class="table-holder"></div>.

Note: if your header has clickable controls then you may need to add some more jQuery script to pass the events raised in cloned header to original header. This code is already available in jQuery sticky-header plugin create by jmosbech

The accepted answer is correct. However, I needed a little bit more clarity, so in case someone else does too:

Leaflet allows events to fire on virtually anything you do on its map, in this case a marker.

So you could create a marker as suggested by the question above:

L.marker([10.496093,-66.881935]).addTo(map).on('mouseover', onClick);

Then create the onClick function:

function onClick(e) {
    alert(this.getLatLng());
}

Now anytime you mouseover that marker it will fire an alert of the current lat/long.

However, you could use 'click', 'dblclick', etc. instead of 'mouseover' and instead of alerting lat/long you can use the body of onClick to do anything else you want:

L.marker([10.496093,-66.881935]).addTo(map).on('click', function(e) {
    console.log(e.latlng);
});

Here is the documentation: http://leafletjs.com/reference.html#events

long l1 = Convert.ToInt64(strValue);

That should do it.

First thing, you should not do any DOM manipulation in controller function. Instead, you should use directives for this purpose. directive's link function is available for those kind of stuff only.

AngularJS Docs : Creating a Directive that Manipulates the DOM

app.directive('buttonDirective', function($timeout) {
  return {
    scope: {
       change: '&'
    },
    link: function(scope, element, attrs) {
      element.bind('click', function() {
        $timeout(function() {
          // triggering callback
          scope.change();
        });
      });
    }
  };
});

change callback can be used as listener for click event.

Consider the Switch Function as an alternative to multiple IIf() expressions. It will return the value from the first expression/value pair where the expression evaluates as True, and ignore any remaining pairs. The concept is similar to the SELECT ... CASE approach you referenced but which is not available in Access SQL.

If you want to display a calculated field as commission:

SELECT
    Switch(
        OpeningBalance < 5001, 20,
        OpeningBalance < 10001, 30,
        OpeningBalance < 20001, 40,
        OpeningBalance >= 20001, 50
        ) AS commission
FROM YourTable;

If you want to store that calculated value to a field named commission:

UPDATE YourTable
SET commission =
    Switch(
        OpeningBalance < 5001, 20,
        OpeningBalance < 10001, 30,
        OpeningBalance < 20001, 40,
        OpeningBalance >= 20001, 50
        );

Either way, see whether you find Switch() easier to understand and manage. Multiple IIf()s can become mind-boggling as the number of conditions grows.

Step 1: Open an elevated Task Scheduler (ie. right-click on the Task Scheduler icon and choose Run as administrator)

Step 2: In the Actions pane (right pane, not the actions tab), click Enable All Tasks History

That's it. Not sure why this isn't on by default, but it isn't.

What to change? Aside from the 3 or 4 dimensional array problem, you should get rid of the magic numbers (10 and 9).

const int DIM_SIZE = 10;
int myArray[DIM_SIZE][DIM_SIZE][DIM_SIZE];

for (int i = 0; i < DIM_SIZE; ++i){
    for (int t = 0; t < DIM_SIZE; ++t){            
        for (int x = 0; x < DIM_SIZE; ++x){

The second method would almost certainly be the fastest way to test whether a null-terminated string is empty, since it involves one read and one comparison. There's certainly nothing wrong with this approach in this case, so you may as well use it.

The third method doesn't check whether a character array is empty; it ensures that a character array is empty.

Nick Vogt at H3XED posted this syntax: https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Take this link and replace the expression "VIDEOID" with the (shortened/shared) ID of the video.

Exapmple for ID: i3jNECZ3ybk looks like this: ... /v/i3jNECZ3ybk?version=3&vq=hd1080

What you get as a result is the standalone 1080p video but not in the Tube environment.

I found an excellent solution to this problem on Mats Karlsson's blog. The solution is to write a subclass of ActionResult that serializes data via JSON.NET, configuring the latter to follow the camelCase convention:

public class JsonCamelCaseResult : ActionResult
{
    public JsonCamelCaseResult(object data, JsonRequestBehavior jsonRequestBehavior)
    {
        Data = data;
        JsonRequestBehavior = jsonRequestBehavior;
    }

    public Encoding ContentEncoding { get; set; }

    public string ContentType { get; set; }

    public object Data { get; set; }

    public JsonRequestBehavior JsonRequestBehavior { get; set; }

    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException("context");
        }
        if (JsonRequestBehavior == JsonRequestBehavior.DenyGet && String.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
        {
            throw new InvalidOperationException("This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet.");
        }

        var response = context.HttpContext.Response;

        response.ContentType = !String.IsNullOrEmpty(ContentType) ? ContentType : "application/json";
        if (ContentEncoding != null)
        {
            response.ContentEncoding = ContentEncoding;
        }
        if (Data == null)
            return;

        var jsonSerializerSettings = new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver()
        };
        response.Write(JsonConvert.SerializeObject(Data, jsonSerializerSettings));
    }
}

Then use this class as follows in your MVC controller method:

public ActionResult GetPerson()
{
    return new JsonCamelCaseResult(new Person { FirstName = "Joe", LastName = "Public" }, JsonRequestBehavior.AllowGet)};
}

If you want to create model along with migration use this command:-

sequelize model:create --name regions --attributes name:string,status:boolean --underscored

--underscored it is used to create column having underscore like:- created_at,updated_at or any other column having underscore and support user defined columns having underscore.

var uploadField = document.getElementById("file");

uploadField.onchange = function() {
    if(this.files[0].size > 2097152){
       alert("File is too big!");
       this.value = "";
    };
};

This example should work fine. I set it up for roughly 2MB, 1MB in Bytes is 1,048,576 so you can multiply it by the limit you need.

Here is the jsfiddle example for more clearence:
https://jsfiddle.net/7bjfr/808/

One idea is to use String... args

public class Sample {
   void demoMethod(String... args) {
      for (String arg : args) {
         System.out.println(arg);
      }
   }
   public static void main(String args[] ) {
      new Sample().demoMethod("ram", "rahim", "robert");
      new Sample().demoMethod("krishna", "kasyap");
      new Sample().demoMethod();
   }
}

Output

ram

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    Date parsed = null;
    try {
        parsed = sdf.parse("02/01/2014");
    } catch (ParseException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    java.sql.Date data = new java.sql.Date(parsed.getTime());
    contato.setDataNascimento( data);

    // Contato DataNascimento era Calendar
    //contato.setDataNascimento(Calendar.getInstance());         

    // grave nessa conexão!!! 
    ContatoDao dao = new ContatoDao("mysql");           

    // método elegante 
    dao.adiciona(contato); 
    System.out.println("Banco: ["+dao.getNome()+"] Gravado! Data: "+contato.getDataNascimento());

Please try this code.....

DataRow dr = dtPrf_Mstr.NewRow();
dtPrf_Mstr.Rows.Add(dr);
GVGLCode.DataSource = dtPrf_Mstr;
GVGLCode.DataBind();
int iCount = GVGLCode.Rows.Count;
for (int i = 0; i < iCount; i++)
{
   GVGLCode.Rows.Remove(GVGLCode.Rows[i]);
}
GVGLCode.DataBind();

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

$num_result = mysql_query("SELECT count(*) as total_count from Students ") or exit(mysql_error());
$row = mysql_fetch_object($num_result);
echo $row->total_count;

i think the setTimeout function that you write is not being run. if you use jquery, you can make it run correctly by doing this :

    function alertMsg() {
      //your func
    }

    $(document).ready(function() {
       setTimeout(alertMsg,3000); 
       // the function you called by setTimeout must not be a string.
    });

To do this, I use a custom filter.

In my app:

myApp.filter('rawHtml', ['$sce', function($sce){
  return function(val) {
    return $sce.trustAsHtml(val);
  };
}]);

Then, in the view:

<h1>{{ stuff.title}}</h1>

<div ng-bind-html="stuff.content | rawHtml"></div>

You can get at the data values like this:

string json = @"
[ 
    { ""General"" : ""At this time we do not have any frequent support requests."" },
    { ""Support"" : ""For support inquires, please see our support page."" }
]";

JArray a = JArray.Parse(json);

foreach (JObject o in a.Children<JObject>())
{
    foreach (JProperty p in o.Properties())
    {
        string name = p.Name;
        string value = (string)p.Value;
        Console.WriteLine(name + " -- " + value);
    }
}

The DDMS tool included in the Android SDK includes a tool for monitoring network traffic. It does not provide the kind of detail you get from tcpdump and similar low level tools, but it is still very useful.

POSIX 7 quotes

POSIX 7 specifies both at http://pubs.opengroup.org/onlinepubs/9699919799/functions/clock_getres.html:

CLOCK_REALTIME:

This clock represents the clock measuring real time for the system. For this clock, the values returned by clock_gettime() and specified by clock_settime() represent the amount of time (in seconds and nanoseconds) since the Epoch.

CLOCK_MONOTONIC (optional feature):

For this clock, the value returned by clock_gettime() represents the amount of time (in seconds and nanoseconds) since an unspecified point in the past (for example, system start-up time, or the Epoch). This point does not change after system start-up time. The value of the CLOCK_MONOTONIC clock cannot be set via clock_settime().

clock_settime() gives an important hint: POSIX systems are able to arbitrarily change CLOCK_REALITME with it, so don't rely on it flowing neither continuously nor forward. NTP could be implemented using clock_settime(), and could only affect CLOCK_REALITME.

The Linux kernel implementation seems to take boot time as the epoch for CLOCK_MONOTONIC: Starting point for CLOCK_MONOTONIC

Using Integer.toHexString(...) is a good answer. But personally prefer to use String.format(...).

Try this sample as a test.

byte[] values = new byte[64];
Arrays.fill(values, (byte)8);  //Fills array with 8 just for test
String valuesStr = "";
for(int i = 0; i < values.length; i++)
    valuesStr += String.format("0x%02x", values[i] & 0xff) + " ";
valuesStr.trim();

1 You can use a drawable

<menu xmlns:android="http://schemas.android.com/apk/res/android">

        android:icon="@drawable/my_item_drawable"
        android:title="@string/menu_item1"
        android:showAsAction="ifRoom" />
</menu>

2 Create a style for the action bar and use a custom background:

<resources>
    <!-- the theme applied to the application or activity -->
    <style name="CustomActivityTheme" parent="@android:style/Theme.Holo">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
        <!-- other activity and action bar styles here -->
    </style>
    <!-- style for the action bar backgrounds -->
    <style name="MyActionBar" parent="@android:style/Widget.Holo.ActionBar">
        <item name="android:background">@drawable/background</item>
        <item name="android:backgroundStacked">@drawable/background</item>
        <item name="android:backgroundSplit">@drawable/split_background</item>
    </style>

First, open your application module build.gradle file.

Check the classpath according to your project dependency. If not change the version of this classpath.

from:

classpath 'com.android.tools.build:gradle:1.0.0'

To:

classpath 'com.android.tools.build:gradle:2.3.2'

or higher version according to your gradle of android studio.

If its still problem, then change buildToolsVersion:

From:

buildToolsVersion '21.0.0'

To:

buildToolsVersion '25.0.0'

then hit 'Try again' and gradle will automatically sync. This will solve it.

Method 1

CURRENT_TIME – Inserts only time
CURRENT_DATE – Inserts only date
CURRENT_TIMESTAMP – Inserts both time and date

CREATE TABLE users(
    id INTEGER PRIMARY KEY,
    username TEXT,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

Method 2

db.execSQL("INSERT INTO users(username, created_at) 
            VALUES('ravitamada', 'datetime()'");

Method 3 Using java Date functions

private String getDateTime() {
        SimpleDateFormat dateFormat = new SimpleDateFormat(
                "yyyy-MM-dd HH:mm:ss", Locale.getDefault());
        Date date = new Date();
        return dateFormat.format(date);
}

ContentValues values = new ContentValues();
values.put('username', 'ravitamada');
values.put('created_at', getDateTime());
// insert the row
long id = db.insert('users', null, values);

You could always check out JMF (Java Media Framework). It is pretty old and abandoned, but it works and I've used it for apps before. Looks like it handles what you're asking for.

I see you have added an answer to your question in SQL Server 2008 you can also do

SELECT 3 + CRYPT_GEN_RANDOM(1) % 4 /*Random number between 3 and 6*/ 
FROM ...

A couple of disadvantages of this method are

1. This is slower than the NEWID() method
2. Even though it is evaluated once per row the query optimiser does not realise this which can lead to odd results.

but just thought I'd add it as another option.

I would suspect that there can be as many as 2**32 -1 numbered match variables, on a 32-bit compiled Perl binary.

This should do what you want:

sed 's/two.*/BLAH/'

$ echo "   one  two  three  five
>    four two  five five six
>    six  one  two seven four" | sed 's/two.*/BLAH/'
   one  BLAH
   four BLAH
   six  one  BLAH

The $ is unnecessary because the .* will finish at the end of the line anyways, and the g at the end is unnecessary because your first match will be the first two to the end of the line.

Standard Security
Data Source=serverName\instanceName;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;

Trusted Connection
Data Source=serverName\instanceName;Initial Catalog=myDataBase;Integrated Security=SSPI;

Here's a good reference on connection strings that I keep handy: ConnectionStrings.com

Here is a simple example:

ThreadTest.java

public class ThreadTest
{
   public static void main(String [] args)
   {
      MyThread t1 = new MyThread(0, 3, 300);
      MyThread t2 = new MyThread(1, 3, 300);
      MyThread t3 = new MyThread(2, 3, 300);

      t1.start();
      t2.start();
      t3.start();
   }
}

MyThread.java

public class MyThread extends Thread
{
   private int startIdx, nThreads, maxIdx;

   public MyThread(int s, int n, int m)
   {
      this.startIdx = s;
      this.nThreads = n;
      this.maxIdx = m;
   }

   @Override
   public void run()
   {
      for(int i = this.startIdx; i < this.maxIdx; i += this.nThreads)
      {
         System.out.println("[ID " + this.getId() + "] " + i);
      }
   }
}

And some output:

[ID 9] 1
[ID 10] 2
[ID 8] 0
[ID 10] 5
[ID 9] 4
[ID 10] 8
[ID 8] 3
[ID 10] 11
[ID 10] 14
[ID 10] 17
[ID 10] 20
[ID 10] 23

An explanation - Each MyThread object tries to print numbers from 0 to 300, but they are only responsible for certain regions of that range. I chose to split it by indices, with each thread jumping ahead by the number of threads total. So t1 does index 0, 3, 6, 9, etc.

Now, without IO, trivial calculations like this can still look like threads are executing sequentially, which is why I just showed the first part of the output. On my computer, after this output thread with ID 10 finishes all at once, followed by 9, then 8. If you put in a wait or a yield, you can see it better:

MyThread.java

System.out.println("[ID " + this.getId() + "] " + i);
Thread.yield();

And the output:

[ID 8] 0
[ID 9] 1
[ID 10] 2
[ID 8] 3
[ID 9] 4
[ID 8] 6
[ID 10] 5
[ID 9] 7

Now you can see each thread executing, giving up control early, and the next executing.

You have a CryptoListPresenter _presenter but you are never initializing it. You should either be doing that when you declare it or in your initState() (or another appropriate but called-before-you-need-it method).

One thing I find that helps is that if I know a member is functionally 'final', to actually set it to final as that way the analyzer complains that it hasn't been initialized.

EDIT:

I see diegoveloper beat me to answering this, and that the OP asked a follow up.

@Jake - it's hard for us to tell without knowing exactly what CryptoListPresenter is, but depending on what exactly CryptoListPresenter actually is, generally you'd do final CryptoListPresenter _presenter = new CryptoListPresenter(...);, or

CryptoListPresenter _presenter;

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

If your array of numbers always is starting with 1 and ending with X then you could use the following formula: sum = x * (x+1) / 2

from 1 till 100 the sum would be 100 * 101 / 2 = 5050

      alert("Right-click menu goes here");
    } 
  }

  function RightMouseDown() { 
    return false; 
  }

div:hover {

}

Where lighten.png is a PNG of a white fill with 50% transparency.

sudo brew is no longer an option so if you install with brew at this point you're going to get 2 really obnoxious things: A: it likes to install into /usr/local/opts or according to this, /usr/local/shared. This isn't a big deal at first but i've had issues with node PATH especially when I installed lint. B: you're kind of stuck with sudo commands until you either uninstall and install it this way or you can get the stack from Bitnami

I recommend this method over the stack option because it's ready to go if you have multiple projects. If you go with the premade MEAN stack you'll have to set up virtual hosts in httpd.conf (more of a pain in this stack than XAMPP)plust the usual update your extra/vhosts.conf and /etc/hosts for every additional project, unless you want to repoint and restart your server when you get done updatading things.

Implement Comparable interface to Fruit.

public class Fruit implements Comparable<Fruit> {

It implements the method

Then do call sort method

Collections.sort(fruitList);

You need to add your tiles into your resource bundle. I mean add all those files to your project make sure to copy all files to project directory option checked.

Basically all you need to do is add $ as prefix at column letter and row number. Please see image below

//Here is the example I used for get the field name also the field value
//Hope This will help to someone
TestModel model = new TestModel ("MyDate", "MyTime", "OUT");
//Get All the fields of the class
 Field[] fields = model.getClass().getDeclaredFields();
//If the field is private make the field to accessible true
fields[0].setAccessible(true);
//Get the field name
  System.out.println(fields[0].getName());
//Get the field value
System.out.println(fields[0].get(model));

You can accept the license agreements of the stated SDKs by going to the SDK Manager (Settings > [Search for Android SDK]) then find the packages noted in the error message and find them there. Chances are, you'll find SDKs that are not fully installed and installing them will ask you to accept the license agreement.

I'm fairly certain that the ls command is for Linux, not Windows (I'm assuming you're using Windows as you referred to cmd, which is the command line for the Windows OS).

You should use dir instead, which is the Windows equivalent of ls.

Edit (since this post seems to be getting so many views :) ):

You can't use ls on cmd as it's not shipped with Windows, but you can use it on other terminal programs (such as GitBash). Note, ls might work on some FTP servers if the servers are linux based and the FTP is being used from cmd.

dir on Windows is similar to ls. To find out the various options available, just do dir/?.

If you really want to use ls, you could install 3rd party tools to allow you to run unix commands on Windows. Such a program is Microsoft Windows Subsystem for Linux (link to docs).

this can also be tried...

SELECT l.ip, tbl2.ip as ip2, tbl2.hostname
FROM   login_log l 
LEFT   JOIN (SELECT ip_location.ip, ip_location.hostname
             FROM ip_location
             WHERE ip_location.ip is null)tbl2

This works for anonymous types, ExpandoObject, Nancy.DynamicDictionary or anything else that can be cast to IDictionary<string, object>.

    public static bool PropertyExists(dynamic obj, string name) {
        if (obj == null) return false;
        if (obj is IDictionary<string, object> dict) {
            return dict.ContainsKey(name);
        }
        return obj.GetType().GetProperty(name) != null;
    }

marshaller.setProperty only works on the JAX-B marshaller from Sun. The question was regarding the JAX-B marshaller from SpringSource, which does not support setProperty.

It declares an rvalue reference (standards proposal doc).

Here's an introduction to rvalue references.

Here's a fantastic in-depth look at rvalue references by one of Microsoft's standard library developers.

CAUTION: the linked article on MSDN ("Rvalue References: C++0x Features in VC10, Part 2") is a very clear introduction to Rvalue references, but makes statements about Rvalue references that were once true in the draft C++11 standard, but are not true for the final one! Specifically, it says at various points that rvalue references can bind to lvalues, which was once true, but was changed.(e.g. int x; int &&rrx = x; no longer compiles in GCC) – drewbarbs Jul 13 '14 at 16:12

The biggest difference between a C++03 reference (now called an lvalue reference in C++11) is that it can bind to an rvalue like a temporary without having to be const. Thus, this syntax is now legal:

T&& r = T();

rvalue references primarily provide for the following:

Move semantics. A move constructor and move assignment operator can now be defined that takes an rvalue reference instead of the usual const-lvalue reference. A move functions like a copy, except it is not obliged to keep the source unchanged; in fact, it usually modifies the source such that it no longer owns the moved resources. This is great for eliminating extraneous copies, especially in standard library implementations.

For example, a copy constructor might look like this:

foo(foo const& other)
{
    this->length = other.length;
    this->ptr = new int[other.length];
    copy(other.ptr, other.ptr + other.length, this->ptr);
}

If this constructor was passed a temporary, the copy would be unnecessary because we know the temporary will just be destroyed; why not make use of the resources the temporary already allocated? In C++03, there's no way to prevent the copy as we cannot determine we were passed a temporary. In C++11, we can overload a move constructor:

foo(foo&& other)
{
   this->length = other.length;
   this->ptr = other.ptr;
   other.length = 0;
   other.ptr = nullptr;
}

Notice the big difference here: the move constructor actually modifies its argument. This would effectively "move" the temporary into the object being constructed, thereby eliminating the unnecessary copy.

The move constructor would be used for temporaries and for non-const lvalue references that are explicitly converted to rvalue references using the std::move function (it just performs the conversion). The following code both invoke the move constructor for f1 and f2:

foo f1((foo())); // Move a temporary into f1; temporary becomes "empty"
foo f2 = std::move(f1); // Move f1 into f2; f1 is now "empty"

Perfect forwarding. rvalue references allow us to properly forward arguments for templated functions. Take for example this factory function:

template <typename T, typename A1>
std::unique_ptr<T> factory(A1& a1)
{
    return std::unique_ptr<T>(new T(a1));
}

If we called factory<foo>(5), the argument will be deduced to be int&, which will not bind to a literal 5, even if foo's constructor takes an int. Well, we could instead use A1 const&, but what if foo takes the constructor argument by non-const reference? To make a truly generic factory function, we would have to overload factory on A1& and on A1 const&. That might be fine if factory takes 1 parameter type, but each additional parameter type would multiply the necessary overload set by 2. That's very quickly unmaintainable.

rvalue references fix this problem by allowing the standard library to define a std::forward function that can properly forward lvalue/rvalue references. For more information about how std::forward works, see this excellent answer.

This enables us to define the factory function like this:

template <typename T, typename A1>
std::unique_ptr<T> factory(A1&& a1)
{
    return std::unique_ptr<T>(new T(std::forward<A1>(a1)));
}

Now the argument's rvalue/lvalue-ness is preserved when passed to T's constructor. That means that if factory is called with an rvalue, T's constructor is called with an rvalue. If factory is called with an lvalue, T's constructor is called with an lvalue. The improved factory function works because of one special rule:

When the function parameter type is of the form T&& where T is a template parameter, and the function argument is an lvalue of type A, the type A& is used for template argument deduction.

Thus, we can use factory like so:

auto p1 = factory<foo>(foo()); // calls foo(foo&&)
auto p2 = factory<foo>(*p1);   // calls foo(foo const&)

Important rvalue reference properties:

• For overload resolution, lvalues prefer binding to lvalue references and rvalues prefer binding to rvalue references. Hence why temporaries prefer invoking a move constructor / move assignment operator over a copy constructor / assignment operator.
• rvalue references will implicitly bind to rvalues and to temporaries that are the result of an implicit conversion. i.e. float f = 0f; int&& i = f; is well formed because float is implicitly convertible to int; the reference would be to a temporary that is the result of the conversion.
• Named rvalue references are lvalues. Unnamed rvalue references are rvalues. This is important to understand why the std::move call is necessary in: foo&& r = foo(); foo f = std::move(r);

Easiest way to use this function is to start by 'Recording a Macro'. Once you start recording, save the file to the location you want, with the name you want, and then of course set the file type, most likely 'Excel Macro Enabled Workbook' ~ 'XLSM'

Stop recording and you can start inspecting your code.

I wrote the code below which allows you to save a workbook using the path where the file was originally located, naming it as "Event [date in cell "A1"]"

Option Explicit

Sub SaveFile()

Dim fdate As Date
Dim fname As String
Dim path As String

fdate = Range("A1").Value
path = Application.ActiveWorkbook.path

If fdate > 0 Then
    fname = "Event " & fdate
    Application.ActiveWorkbook.SaveAs Filename:=path & "\" & fname, _
        FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
Else
    MsgBox "Chose a date for the event", vbOKOnly
End If

End Sub

Copy the code into a new module and then write a date in cell "A1" e.g. 01-01-2016 -> assign the sub to a button and run. [Note] you need to make a save file before this script will work, because a new workbook is saved to the default autosave location!

Using Apache Commons IO.

import org.apache.commons.io.FileUtils;

//...

String contents = FileUtils.readFileToString(new File("/path/to/the/file"), "UTF-8")

You can see de javadoc for the method for details.

*ngIf removes the element from the DOM when the expression becomes false. You can't have a transition on a non-existing element.

Use instead hidden:

<div class="note" [ngClass]="{'transition':show}" [hidden]="!show">

pls check this: import numbers

import math

a = 1.1 - 0.1
print a 

print isinstance(a, numbers.Integral)
print math.floor( a )
if (math.floor( a ) == a):
    print "It is an integer number"
else:
    print False

Although X is float but the value is integer, so if you want to check the value is integer you cannot use isinstance and you need to compare values not types.

I once got into the same problem and found this solution with respect to my needs. It may help Some one.

<input type="number" placeholder="Enter 4 Digits" max="9999" min="0" 
onKeyDown="if(this.value.length==4 && event.keyCode>47 && event.keyCode < 58)return false;"
/>

Happy Coding :)

but as for this method, I don't understand the purpose of Integer.MAX_VALUE and Integer.MIN_VALUE.

By starting out with smallest set to Integer.MAX_VALUE and largest set to Integer.MIN_VALUE, they don't have to worry later about the special case where smallest and largest don't have a value yet. If the data I'm looking through has a 10 as the first value, then numbers[i]<smallest will be true (because 10 is < Integer.MAX_VALUE) and we'll update smallest to be 10. Similarly, numbers[i]>largest will be true because 10 is > Integer.MIN_VALUE and we'll update largest. And so on.

Of course, when doing this, you must ensure that you have at least one value in the data you're looking at. Otherwise, you end up with apocryphal numbers in smallest and largest.

Note the point Onome Sotu makes in the comments:

...if the first item in the array is larger than the rest, then the largest item will always be Integer.MIN_VALUE because of the else-if statement.

Which is true; here's a simpler example demonstrating the problem (live copy):

public class Example
{
    public static void main(String[] args) throws Exception {
        int[] values = {5, 1, 2};
        int smallest = Integer.MAX_VALUE;
        int largest  = Integer.MIN_VALUE;
        for (int value : values) {
            if (value < smallest) {
                smallest = value;
            } else if (value > largest) {
                largest = value;
            }
        }
        System.out.println(smallest + ", " + largest); // 1, 2 -- WRONG
    }
}

To fix it, either:

1. Don't use else, or

2. Start with smallest and largest equal to the first element, and then loop the remaining elements, keeping the else if.

Here's an example of that second one (live copy):

public class Example
{
    public static void main(String[] args) throws Exception {
        int[] values = {5, 1, 2};
        int smallest = values[0];
        int largest  = values[0];
        for (int n = 1; n < values.length; ++n) {
            int value = values[n];
            if (value < smallest) {
                smallest = value;
            } else if (value > largest) {
                largest = value;
            }
        }
        System.out.println(smallest + ", " + largest); // 1, 5
    }
}

Register this class by @Component annotation or in xml

<bean class="ua.adeptius.PostProxyInvokerContextListener"/>

and use annotation where you wan on any method that you want to run after context initialized, like:

Google Maps API v3:

I initialized Google Map and added markers to it. Later, I wanted to retrieve all markers and did it simply by accessing the map property "markers".

var map = new GMaps({
    div: '#map',
    lat: 40.730610,
    lng: -73.935242,
});

var myMarkers = map.markers;

You can loop over it and access all Marker methods listed at Google Maps Reference.

Rule of three in C++ is a fundamental principle of the design and the development of three requirements that if there is clear definition in one of the following member function, then the programmer should define the other two members functions together. Namely the following three member functions are indispensable: destructor, copy constructor, copy assignment operator.

Copy constructor in C++ is a special constructor. It is used to build a new object, which is the new object equivalent to a copy of an existing object.

Copy assignment operator is a special assignment operator that is usually used to specify an existing object to others of the same type of object.

There are quick examples:

// default constructor
My_Class a;

// copy constructor
My_Class b(a);

// copy constructor
My_Class c = a;

// copy assignment operator
b = a;

Case 1: Insert Row and Query Foreign Key

Here is an alternate syntax I use:

INSERT INTO tab_student 
   SET name_student = 'Bobby Tables',
       id_teacher_fk = (
       SELECT id_teacher
         FROM tab_teacher
        WHERE name_teacher = 'Dr. Smith')

I'm doing this in Excel to import a pivot table to a dimension table and a fact table in SQL so you can import to both department and expenses tables from the following:

Case 2: Insert Row and Then Insert Dependant Row

Luckily, MySQL supports LAST_INSERT_ID() exactly for this purpose.

INSERT INTO tab_teacher
   SET name_teacher = 'Dr. Smith';
INSERT INTO tab_student 
   SET name_student = 'Bobby Tables',
       id_teacher_fk = LAST_INSERT_ID()

I invite you to explore what Python 3.8 has to offer for the subject matter in form of Structural subtyping (static duck typing) (PEP 544)

See the short description https://docs.python.org/3/library/typing.html#typing.Protocol

For the simple example here it goes like this:

from typing import Protocol

class MyShowProto(Protocol):
    def show(self):
        ...


class MyClass:
    def show(self):
        print('Hello World!')


class MyOtherClass:
    pass


def foo(o: MyShowProto):
    return o.show()

foo(MyClass())  # ok
foo(MyOtherClass())  # fails

foo(MyOtherClass()) will fail static type checks:

$ mypy proto-experiment.py 
proto-experiment.py:21: error: Argument 1 to "foo" has incompatible type "MyOtherClass"; expected "MyShowProto"
Found 1 error in 1 file (checked 1 source file)

In addition, you can specify the base class explicitly, for instance:

class MyOtherClass(MyShowProto):

but note that this makes methods of the base class actually available on the subclass, and thus the static checker will not report that a method definition is missing on the MyOtherClass. So in this case, in order to get a useful type-checking, all the methods that we want to be explicitly implemented should be decorated with @abstractmethod:

from typing import Protocol
from abc import abstractmethod

class MyShowProto(Protocol):
    @abstractmethod
    def show(self): raise NotImplementedError


class MyOtherClass(MyShowProto):
    pass


MyOtherClass()  # error in type checker

I had the same issue I remove the following script and it worked for me.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>

Just turn off the firewall and remove the instance configuration. Add a new instance for the server.![Disable Firewall][1] Give he port number correctly as 3306 as default

You can use any of these two:

return redirect()->back()->withInput(Input::all())->with('message', 'Some message');

Or,

return redirect('url_goes_here')->withInput(Input::all())->with('message', 'Some message');

In this case I think you need transform the date to UNIX timestamp

timestamp = testDate.getTime();
strJson = JSON.stringify(timestamp);

After that you can re use it to create a date object and format it. Example with javascript and toLocaleDateString ( https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Objets_globaux/Date/toLocaleDateString )

newDateObject = new Date(JSON.parse(strJson));
newDateObject = newDateObject.toLocalDateStrin([
  "fr-FR",
]);

If you use stringify to use AJAX, now it's not useful. You just need to send timestamp and get it in your script:

$newDateObject = new \DateTime();
$newDateObject->setTimestamp(round($timestamp/1000));

Be aware that getTime() will return a time in milliseconds and the PHP function setTimestamp take time in seconds. It's why you need to divide by 1000 and round.

A derived class is not the the same class as its base class and you may or may not care whether any members of the base class are initialized at the time of the construction of the derived class. That is a determination made by the programmer not by the compiler.

Use master.dbo.fn_varbintohexsubstring(0, HashBytes('SHA1', @input), 1, 0) instead of master.dbo.fn_varbintohexstr and then substringing the result.

In fact fn_varbintohexstr calls fn_varbintohexsubstring internally. The first argument of fn_varbintohexsubstring tells it to add 0xF as the prefix or not. fn_varbintohexstr calls fn_varbintohexsubstring with 1 as the first argument internaly.

Because you don't need 0xF, call fn_varbintohexsubstring directly.

For all example below you need to import fs and path modules:

const fs = require('fs');
const path = require('path');

Read files asynchronously

function readFiles(dir, processFile) {
  // read directory
  fs.readdir(dir, (error, fileNames) => {
    if (error) throw error;

    fileNames.forEach(filename => {
      // get current file name
      const name = path.parse(filename).name;
      // get current file extension
      const ext = path.parse(filename).ext;
      // get current file path
      const filepath = path.resolve(dir, filename);

      // get information about the file
      fs.stat(filepath, function(error, stat) {
        if (error) throw error;

        // check if the current path is a file or a folder
        const isFile = stat.isFile();

        // exclude folders
        if (isFile) {
          // callback, do something with the file
          processFile(filepath, name, ext, stat);
        }
      });
    });
  });
}

Usage:

// use an absolute path to the folder where files are located
readFiles('absolute/path/to/directory/', (filepath, name, ext, stat) => {
  console.log('file path:', filepath);
  console.log('file name:', name);
  console.log('file extension:', ext);
  console.log('file information:', stat);
});

Read files synchronously, store in array, natural sorting

/**
 * @description Read files synchronously from a folder, with natural sorting
 * @param {String} dir Absolute path to directory
 * @returns {Object[]} List of object, each object represent a file
 * structured like so: `{ filepath, name, ext, stat }`
 */
function readFilesSync(dir) {
  const files = [];

  fs.readdirSync(dir).forEach(filename => {
    const name = path.parse(filename).name;
    const ext = path.parse(filename).ext;
    const filepath = path.resolve(dir, filename);
    const stat = fs.statSync(filepath);
    const isFile = stat.isFile();

    if (isFile) files.push({ filepath, name, ext, stat });
  });

  files.sort((a, b) => {
    // natural sort alphanumeric strings
    // https://stackoverflow.com/a/38641281
    return a.name.localeCompare(b.name, undefined, { numeric: true, sensitivity: 'base' });
  });

  return files;
}

Usage:

// return an array list of objects
// each object represent a file
const files = readFilesSync('absolute/path/to/directory/');

Read files async using promise

More info on promisify in this article.

const { promisify } = require('util');

const readdir_promise = promisify(fs.readdir);
const stat_promise = promisify(fs.stat);

function readFilesAsync(dir) {
  return readdir_promise(dir, { encoding: 'utf8' })
    .then(filenames => {
      const files = getFiles(dir, filenames);

      return Promise.all(files);
    })
    .catch(err => console.error(err));
}

function getFiles(dir, filenames) {
  return filenames.map(filename => {
    const name = path.parse(filename).name;
    const ext = path.parse(filename).ext;
    const filepath = path.resolve(dir, filename);

    return stat({ name, ext, filepath });
  });
}

function stat({ name, ext, filepath }) {
  return stat_promise(filepath)
    .then(stat => {
      const isFile = stat.isFile();

      if (isFile) return { name, ext, filepath, stat };
    })
    .catch(err => console.error(err));
}

Usage:

readFiles('absolute/path/to/directory/')
  // return an array list of objects
  // each object is a file
  // with those properties: { name, ext, filepath, stat }
  .then(files => console.log(files))
  .catch(err => console.log(err));

Note: return undefined for folders, if you want you can filter them out:

readFiles('absolute/path/to/directory/')
  .then(files => files.filter(file => file !== undefined))
  .catch(err => console.log(err));

Google's R style guide simplifies the issue by prohibiting the "=" for assignment. Not a bad choice.

The R manual goes into nice detail on all 5 assignment operators.

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

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

To iterate on Avi Flax answer Object.keys(obj).length is correct for an object that doesnt have functions tied to it

example:

obj = {"lol": "what", owo: "pfft"};
Object.keys(obj).length; // should be 2

versus

arr = [];
obj = {"lol": "what", owo: "pfft"};
obj.omg = function(){
    _.each(obj, function(a){
        arr.push(a);
    });
};
Object.keys(obj).length; // should be 3 because it looks like this 
/* obj === {"lol": "what", owo: "pfft", omg: function(){_.each(obj, function(a){arr.push(a);});}} */

steps to avoid this:

1. do not put functions in an object that you want to count the number of keys in

2. use a seperate object or make a new object specifically for functions (if you want to count how many functions there are in the file using Object.keys(obj).length)

also yes i used the _ or underscore module from nodejs in my example

documentation can be found here http://underscorejs.org/ as well as its source on github and various other info

And finally a lodash implementation https://lodash.com/docs#size

_.size(obj)

The easiest method without using javaScript is to put all your <select> dropdown inside a <form> tag and use form reset button. Example:

<form>
  <select>
    <option>one</option>
    <option>two</option>
    <option selected>three</option>
  </select>
  <input type="reset" value="Reset" />
</form>

Or, using JavaScript, it can be done in following way:

HTML Code:

<select>
  <option selected>one</option>
  <option>two</option>
  <option>three</option>
</select>
<button id="revert">Reset</button>

And JavaScript code:

const button = document.getElementById("revert");
const options = document.querySelectorAll('select option');
button.onclick = () => {
  for (var i = 0; i < options.length; i++) {
    options[i].selected = options[i].defaultSelected;
  }
}

Both of these methods will work if you have multiple selected items or single selected item.

You need %in% instead of ==:

library(dplyr)
target <- c("Tom", "Lynn")
filter(dat, name %in% target)  # equivalently, dat %>% filter(name %in% target)

Produces

  days name
1   88 Lynn
2   11  Tom
3    1  Tom
4  222 Lynn
5    2 Lynn

To understand why, consider what happens here:

dat$name == target
# [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE

Basically, we're recycling the two length target vector four times to match the length of dat$name. In other words, we are doing:

 Lynn == Tom
  Tom == Lynn
Chris == Tom
 Lisa == Lynn
 ... continue repeating Tom and Lynn until end of data frame

In this case we don't get an error because I suspect your data frame actually has a different number of rows that don't allow recycling, but the sample you provide does (8 rows). If the sample had had an odd number of rows I would have gotten the same error as you. But even when recycling works, this is clearly not what you want. Basically, the statement dat$name == target is equivalent to saying:

return TRUE for every odd value that is equal to "Tom" or every even value that is equal to "Lynn".

It so happens that the last value in your sample data frame is even and equal to "Lynn", hence the one TRUE above.

To contrast, dat$name %in% target says:

for each value in dat$name, check that it exists in target.

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Note your problem has nothing to do with dplyr, just the mis-use of ==.

Default behaviour of PowerShell is just to dump everything that falls out of a pipeline without being picked up by another pipeline element or being assigned to a variable (or redirected) into Out-Host. What Out-Host does is obviously host-dependent.

Just letting things fall out of the pipeline is not a substitute for Write-Host which exists for the sole reason of outputting text in the host application.

If you want output, then use the Write-* cmdlets. If you want return values from a function, then just dump the objects there without any cmdlet.

Since this must have an input element as a parent, you could just use

<input type="text" ng-model="foo" ng-change="myOnChangeFunction()">

Alternatively, you could use the ngModelController and add a function to $formatters, which executes functions on input change. See http://docs.angularjs.org/api/ng.directive:ngModel.NgModelController

.directive("myDirective", function() {
  return {
    restrict: 'A',
    require: 'ngModel',
    link: function(scope, element, attr, ngModel) {
      ngModel.$formatters.push(function(value) {
        // Do stuff here, and return the formatted value.
      });
  };
};

You can handle the keydown event of your TextBox control.

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if(e.KeyCode==Keys.Enter)
    buttonSearch_Click(sender,e);
}

It works even when the button Visible property is set to false

The error log is straightforward. As it suggested,You need to add 198.211.99.20 to your ALLOWED_HOSTS setting.

In your project settings.py file,set ALLOWED_HOSTS like this :

ALLOWED_HOSTS = ['198.211.99.20', 'localhost', '127.0.0.1']

For further reading read from here.

No. Only object references can be null, not primitives.

This code is working fine for me. Can you please check:

<input type="number" name="test" min="0" oninput="validity.valid||(value='');">

You should be able to adjust the width using the .modal-dialog class selector (in conjunction with media queries or whatever strategy you're using for responsive design):

.modal-dialog {
    width: 400px;
}

Actually, the default directory where the mongod instance stores its data is

/data/db on Linux and OS X,

\data\db on Windows

To check the same, you can look for dbPath settings in mongodb configuration file.

• On Linux, the location is /etc/mongod.conf, if you have used package manager to install MongoDB. Run the following command to check the specified directory:

  grep dbpath /etc/mongodb.conf
  

• On Windows, the location is <install directory>/bin/mongod.cfg. Open mongod.cfg file and check for dbPath option.
• On macOS, the location is /usr/local/etc/mongod.conf when installing from MongoDB’s official Homebrew tap.

The default mongod.conf configuration file included with package manager installations uses the following platform-specific default values for storage.dbPath:

+--------------------------+-----------------+------------------------+
|         Platform         | Package Manager | Default storage.dbPath |
+--------------------------+-----------------+------------------------+
| RHEL / CentOS and Amazon | yum             | /var/lib/mongo         |
| SUSE                     | zypper          | /var/lib/mongo         |
| Ubuntu and Debian        | apt             | /var/lib/mongodb       |
| macOS                    | brew            | /usr/local/var/mongodb |
+--------------------------+-----------------+------------------------+

The storage.dbPath setting in the configuration file is available only for mongod.

The Linux package init scripts do not expect storage.dbPath to change from the defaults. If you use the Linux packages and change storage.dbPath, you will have to use your own init scripts and disable the built-in scripts.

If you want specifically do something when click on close button exactly like you described:

<a href="#" class="btn close_link" data-dismiss="modal">Close</a>

you need to attach an event using css selector:

$(document).on('click', '[data-dismiss="modal"]', function(){what you want to do})

But if you want to do something when modal close, you can use the already wrote tips

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

I know this is an old Question, but it popped up when I was looking for a solution to the same issue, so I thought that I would post what worked for me.

<asp:BoundField DataField="Description" HeaderText="Bond Event" ItemStyle-Width="300px" />

I used the ItemStyle-Width attribute on my BoundField and it worked very nicely I haven't had any issues yet.

I didn't need to add anything else to the rest of the code to make this work either.

You can add this in your css file:

[data-role=page]{height: 100% !important; position:relative !important;}
[data-role=footer]{bottom:0; position:absolute !important; top: auto !important; width:100%;}  

So the page data-role now have 100% height, and footer is in absolute position.

Also Yappo have wrote an excellent plugin that you can find here: jQuery Mobile in a iScroll plugin http://yappo.github.com/projects/jquery.mobile.iscroll/livedemo.html

hope you found the answer!

An answer update

You can now use the data-position="fixed" attribute to keep your footer element on the bottom.

Here's an interface for objects that have a rectangular shape:

interface IRectangular
{
    Int32 Width();
    Int32 Height();
}

All it demands is that you implement ways to access the width and height of the object.

Now let's define a method that will work on any object that is IRectangular:

static class Utils
{
    public static Int32 Area(IRectangular rect)
    {
        return rect.Width() * rect.Height();
    }
}

That will return the area of any rectangular object.

Let's implement a class SwimmingPool that is rectangular:

class SwimmingPool : IRectangular
{
    int width;
    int height;

    public SwimmingPool(int w, int h)
    { width = w; height = h; }

    public int Width() { return width; }
    public int Height() { return height; }
}

And another class House that is also rectangular:

class House : IRectangular
{
    int width;
    int height;

    public House(int w, int h)
    { width = w; height = h; }

    public int Width() { return width; }
    public int Height() { return height; }
}

Given that, you can call the Area method on houses or swimming-pools:

var house = new House(2, 3);

var pool = new SwimmingPool(3, 4);

Console.WriteLine(Utils.Area(house));
Console.WriteLine(Utils.Area(pool));

In this way, your classes can "inherit" behavior (static-methods) from any number of interfaces.

I was seeing this same error when trying to save an excel file. The code worked fine when I was using MS Office 2003, but after upgrading to MS Office 2007 I started seeing this. It would happen anytime I tried to save an Excel file to a server or remote fie share.

My solution, though rudimentary, worked well. I just had the program save the file locally, like to the user's C:\ drive. Then use the "System.IO.File.Copy(File, Destination, Overwrite)" method to move the file to the server. Then you can delete the file on the C:\ drive.

Works great, and simple. But admittedly not the most elegant approach.

Hope this helps! I was having a ton of trouble finding any solutions on the web till this idea popped into my head.

text = text.replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/\n/g, '<br/>');

here is my take on it. This is good for displaying multiple results just in case you need one. So I added the list as well

myList = {'george':16,'amber':19, 'rachel':19, 
           'david':15 }                         #Setting the dictionary
result=[]                                       #Making ready of the result list
search_age = int(input('Enter age '))

for keywords in myList.keys():
    if myList[keywords] ==search_age:
    result.append(keywords)                    #This part, we are making list of results

for res in result:                             #We are now printing the results
    print(res)

And that's it...

You should use getFullYear() instead of getYear(). getYear() returns the actual year minus 1900 (and so is fairly useless).

Thus a date marking exactly one year from the present moment would be:

var oneYearFromNow = new Date();
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);

Note that the date will be adjusted if you do that on February 29.

Similarly, you can get a date that's a month from now via getMonth() and setMonth(). You don't have to worry about "rolling over" from the current year into the next year if you do it in December; the date will be adjusted automatically. Same goes for day-of-month via getDate() and setDate().

Here's a different way to do it, but it's only useful if SecondDate is a variable you're passing in:

DateTime startDate = SecondDate.Date;
DateTime endDate = startDate.AddDays(1).AddTicks(-1);
...
e => e.FirstDate.Value >= startDate && e.FirstDate.Value <= endDate

I think that should work

Actually you're close to your goal, you just need to use nodes() method to split your rows and then get values:

select
    s.SqmId,
    m.c.value('@id', 'varchar(max)') as id,
    m.c.value('@type', 'varchar(max)') as type,
    m.c.value('@unit', 'varchar(max)') as unit,
    m.c.value('@sum', 'varchar(max)') as [sum],
    m.c.value('@count', 'varchar(max)') as [count],
    m.c.value('@minValue', 'varchar(max)') as minValue,
    m.c.value('@maxValue', 'varchar(max)') as maxValue,
    m.c.value('.', 'nvarchar(max)') as Value,
    m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
    outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)

If you want to get value from a mapped select input then you can refer to this example:

class App extends React.Component {
      constructor(props) {
        super(props);
        this.state = {
          fruit: "banana",
        };
    
        this.handleChange = this.handleChange.bind(this);
      }
    
      handleChange(e) {
        console.log("Fruit Selected!!");
        this.setState({ fruit: e.target.value });
      }
    
      render() {
        return (
          <div id="App">
            <div className="select-container">
              <select value={this.state.fruit} onChange={this.handleChange}>
                {options.map((option) => (
                  <option value={option.value}>{option.label}</option>
                ))}
              </select>
            </div>
          </div>
        );
      }
    }
    
    export default App;

Rolo's answer is excellent, however I had to reinstall Pillow by bypassing pip cache (introduced with pip 7) otherwise it won't get properly recompiled!!! The command is:

pip install -I --no-cache-dir -v Pillow

and you can see if Pillow has been properly configured by reading in the logs this:

I try to explain this problem step by step in following example.

0) Question

I try to ask you like this :

i want to open page like facebook profile www.facebook.com/kaila.piyush

it get id from url and parse it to profile.php file and return featch data from database and show user to his profile

normally when we develope any website its link look like www.website.com/profile.php?id=username example.com/weblog/index.php?y=2000&m=11&d=23&id=5678

now we update with new style not rewrite we use www.website.com/username or example.com/weblog/2000/11/23/5678 as permalink

http://example.com/profile/userid (get a profile by the ID) 
http://example.com/profile/username (get a profile by the username) 
http://example.com/myprofile (get the profile of the currently logged-in user)

1) .htaccess

Create a .htaccess file in the root folder or update the existing one :

Options +FollowSymLinks
# Turn on the RewriteEngine
RewriteEngine On
#  Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php

What does that do ?

If the request is for a real directory or file (one that exists on the server), index.php isn't served, else every url is redirected to index.php.

2) index.php

Now, we want to know what action to trigger, so we need to read the URL :

In index.php :

// index.php    

// This is necessary when index.php is not in the root folder, but in some subfolder...
// We compare $requestURL and $scriptName to remove the inappropriate values
$requestURI = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
$scriptName = explode(‘/’,$_SERVER[‘SCRIPT_NAME’]);

for ($i= 0; $i < sizeof($scriptName); $i++)
{
    if ($requestURI[$i] == $scriptName[$i])
    {
        unset($requestURI[$i]);
    }
}

$command = array_values($requestURI);
With the url http://example.com/profile/19837, $command would contain :

$command = array(
    [0] => 'profile',
    [1] => 19837,
    [2] => ,
)
Now, we have to dispatch the URLs. We add this in the index.php :

// index.php

require_once("profile.php"); // We need this file
switch($command[0])
{
    case ‘profile’ :
        // We run the profile function from the profile.php file.
        profile($command([1]);
        break;
    case ‘myprofile’ :
        // We run the myProfile function from the profile.php file.
        myProfile();
        break;
    default:
        // Wrong page ! You could also redirect to your custom 404 page.
        echo "404 Error : wrong page.";
        break;
}

2) profile.php

Now in the profile.php file, we should have something like this :

// profile.php

function profile($chars)
{
    // We check if $chars is an Integer (ie. an ID) or a String (ie. a potential username)

    if (is_int($chars)) {
        $id = $chars;
        // Do the SQL to get the $user from his ID
        // ........
    } else {
        $username = mysqli_real_escape_string($char);
        // Do the SQL to get the $user from his username
        // ...........
    }

    // Render your view with the $user variable
    // .........
}

function myProfile()
{
    // Get the currently logged-in user ID from the session :
    $id = ....

    // Run the above function :
    profile($id);
}

May this help to someone if they have the same requirement.

I had the same problem with spring boot. It resolved when i set package to marshaller.

@Bean
public Jaxb2Marshaller marshaller() throws Exception
{
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setPackagesToScan("com.octory.ws.dto");
    return marshaller;
}

@Bean
public WebServiceTemplate webServiceTemplate(final Jaxb2Marshaller marshaller)   
{
    WebServiceTemplate webServiceTemplate = new WebServiceTemplate();
    webServiceTemplate.setMarshaller(marshaller);
    webServiceTemplate.setUnmarshaller(marshaller);
    return webServiceTemplate;
}

To extend the previous answer even more, like Ankit was saying, for complex objects you need to implement Serializable. For example, for the simple object:

public class MyClass implements Serializable {
    private static final long serialVersionUID = -2163051469151804394L;
    private int id;
    private String created;
}

In you FromFragment:

Bundle args = new Bundle();
args.putSerializable(TAG_MY_CLASS, myClass);
Fragment toFragment = new ToFragment();
toFragment.setArguments(args);
getFragmentManager()
    .beginTransaction()
    .replace(R.id.body, toFragment, TAG_TO_FRAGMENT)
    .addToBackStack(TAG_TO_FRAGMENT).commit();

in your ToFragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

    Bundle args = getArguments();
    MyClass myClass = (MyClass) args
        .getSerializable(TAG_MY_CLASS);

There are a couple of parallization bugs in SQL server with abnormal input. OPTION(MAXDOP 1) will sidestep them.

EDIT: Old. My testing was done largely on SQL 2005. Most of these seem to not exist anymore, but every once in awhile we question the assumption when SQL 2014 does something dumb and we go back to the old way and it works. We never managed to demonstrate that it wasn't just a bad plan generation on more recent cases though since SQL server can be relied on to get the old way right in newer versions. Since all cases were IO bound queries MAXDOP 1 doesn't hurt.

I had a Same Problem but i solved by Restarting the browser service in SQL CONFIGURATION MANAGER and removing \SQLEXPRESS from the instance name in the connection window.

To anyone who had been wonderstruck about some files being easily uploaded and some not, it could be a size issue. I'm sharing this as I was stuck with my PHP code not uploading large files and I kept assuming it wasn't uploading any Excel files. So, if you are using PHP and you want to increase the file upload limit, go to the php.ini file and make the following modifications:

• upload_max_filesize = 2M

to be changed to

• upload_max_filesize = 10M

• post_max_size = 10M

or the size required. Then restart the Apache server and the upload will start magically working. Hope this will be of help to someone.

You can use something like ini_set('session.gc_maxlifetime', 28800); // 8 * 60 * 60 too.

Kenny's solution is good, however it can be written in a more elegant way

new WebDriverWait(driver, timeout)
        .ignoring(StaleElementReferenceException.class)
        .until((WebDriver d) -> {
            d.findElement(By.id("checkoutLink")).click();
            return true;
        });

Or also:

new WebDriverWait(driver, timeout).ignoring(StaleElementReferenceException.class).until(ExpectedConditions.elementToBeClickable(By.id("checkoutLink")));
driver.findElement(By.id("checkoutLink")).click();

But anyway, best solution is to rely on Selenide library, it handles this kind of things and more. (instead of element references it handles proxies so you never have to deal with stale elements, which can be quite difficult). Selenide

You can add timeout function in jQuery (Show alert after 3 seconds):

$(document).ready(function($) {
    setTimeout(function() {
     alert("Hello");
    }, 3000);
});

Here's what worked for me:

You can do by using reflection:

public void AddFruit<T>()where T: BaseFruit
{
  ConstructorInfo constructor = typeof(T).GetConstructor(new Type[] { typeof(int) });
  if (constructor == null)
  {
    throw new InvalidOperationException("Type " + typeof(T).Name + " does not contain an appropriate constructor");
  }
  BaseFruit fruit = constructor.Invoke(new object[] { (int)150 }) as BaseFruit;
  fruit.Enlist(fruitManager);
}

EDIT: Added constructor == null check.

EDIT: A faster variant using a cache:

public void AddFruit<T>()where T: BaseFruit
{
  var constructor = FruitCompany<T>.constructor;
  if (constructor == null)
  {
    throw new InvalidOperationException("Type " + typeof(T).Name + " does not contain an appropriate constructor");
  }
  var fruit = constructor.Invoke(new object[] { (int)150 }) as BaseFruit;
  fruit.Enlist(fruitManager);
}
private static class FruitCompany<T>
{
  public static readonly ConstructorInfo constructor = typeof(T).GetConstructor(new Type[] { typeof(int) });
}

We can also pass controller function as variable in the view page.

class My_controller extends CI_Controller {
    public function index() {
           $data['val']=3;
           $data['square']=function($val){
                               return $val*$val;
                                   };
    $this->load->view('my-view',$data);
}
}

In the view page

<p>Square of <?=$val?>
   <?php 
     echo $square($val); 
   ?>
</p>

The output is 9

A color value has more than one dimension, so there is no intrinsic way to compare two colors. You have to determine for your use case the meaning of the colors and thereby how to best compare them.

Most likely you want to compare the hue, saturation and/or lightness properties of the colors as oppposed to the red/green/blue components. If you are having trouble figuring out how you want to compare them, take some pairs of sample colors and compare them mentally, then try to justify/explain to yourself why they are similar/different.

Once you know which properties/components of the colors you want to compare, then you need to figure out how to extract that information from a color.

Most likely you will just need to convert the color from the common RedGreenBlue representation to HueSaturationLightness, and then calculate something like

avghue = (color1.hue + color2.hue)/2
distance = abs(color1.hue-avghue)

This example would give you a simple scalar value indicating how far the gradient/hue of the colors are from each other.

See HSL and HSV at Wikipedia.

When using the answer from David Poole I get a SystemError with gray scale PNGs and maybe other files. My solution is:

import numpy as np
from PIL import Image

img = Image.open( filename )
try:
    data = np.asarray( img, dtype='uint8' )
except SystemError:
    data = np.asarray( img.getdata(), dtype='uint8' )

Actually img.getdata() would work for all files, but it's slower, so I use it only when the other method fails.

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

HTTP/2 supports queries multiplexing, headers compression, priority and more intelligent packet streaming management. This results in reduced latency and accelerates content download on modern web pages.

First, generate an Interface

Assuming you are using TypeScript & Angular CLI, you can generate one by using the following command

ng g interface car

After that set the data types of its properties

// car.interface.ts
export interface car {
  id: number;
  eco: boolean;
  wheels: number;
  name: string;
}

You can now import your interface in the class that you want.

import {car} from "app/interfaces/car.interface";

And update the collection/array of car objects by pushing items in the array.

this.car.push({
  id: 12345,
  eco: true,
  wheels: 4,
  name: 'Tesla Model S',
});

More on interfaces:

An interface is a TypeScript artifact, it is not part of ECMAScript. An interface is a way to define a contract on a function with respect to the arguments and their type. Along with functions, an interface can also be used with a Class as well to define custom types. An interface is an abstract type, it does not contain any code as a class does. It only defines the 'signature' or shape of an API. During transpilation, an interface will not generate any code, it is only used by Typescript for type checking during development. - https://angular-2-training-book.rangle.io/handout/features/interfaces.html

Given the following tables..

Domain Table
dom_id | dom_url

Review Table
rev_id | rev_dom_from | rev_dom_for

Try this sql... (It's pretty much the same thing that Stephen Wrighton wrote above) The trick is that you are basically selecting from the domain table twice in the same query and joining the results.

Select d1.dom_url, d2.dom_id from
review r, domain d1, domain d2
where d1.dom_id = r.rev_dom_from
and d2.dom_id = r.rev_dom_for

If you are still stuck, please be more specific with exactly it is that you don't understand.

This error means you can not directly load data from file system because there are security issues behind this. The only solution that I know is create a web service to serve load files.

Yes: you can sort using a custom comparison function:

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

my_custom_comparison needs to be a function or a class with an operator() overload (a functor) that takes two data objects and returns a bool indicating whether the first is ordered prior to the second (i.e., first < second). Alternatively, you can overload operator< for your class type data; operator< is the default ordering used by std::sort.

Either way, the comparison function must yield a strict weak ordering of the elements.

Convert.ToString can be used to convert a number to its equivalent string representation in a specified base.

Example:

string binary = Convert.ToString(5, 2); // convert 5 to its binary representation
Console.WriteLine(binary);              // prints 101

However, as pointed out by the comments, Convert.ToString only supports the following limited - but typically sufficient - set of bases: 2, 8, 10, or 16.

Update (to meet the requirement to convert to any base):

I'm not aware of any method in the BCL which is capable to convert numbers to any base so you would have to write your own small utility function. A simple sample would look like that (note that this surely can be made faster by replacing the string concatenation):

class Program
{
    static void Main(string[] args)
    {
        // convert to binary
        string binary = IntToString(42, new char[] { '0', '1' });

        // convert to hexadecimal
        string hex = IntToString(42, 
            new char[] { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
                         'A', 'B', 'C', 'D', 'E', 'F'});

        // convert to hexavigesimal (base 26, A-Z)
        string hexavigesimal = IntToString(42, 
            Enumerable.Range('A', 26).Select(x => (char)x).ToArray());

        // convert to sexagesimal
        string xx = IntToString(42, 
            new char[] { '0','1','2','3','4','5','6','7','8','9',
            'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',
            'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x'});
    }

    public static string IntToString(int value, char[] baseChars)
    {
        string result = string.Empty;
        int targetBase = baseChars.Length;

        do
        {
            result = baseChars[value % targetBase] + result;
            value = value / targetBase;
        } 
        while (value > 0);

        return result;
    }

    /// <summary>
    /// An optimized method using an array as buffer instead of 
    /// string concatenation. This is faster for return values having 
    /// a length > 1.
    /// </summary>
    public static string IntToStringFast(int value, char[] baseChars)
    {
        // 32 is the worst cast buffer size for base 2 and int.MaxValue
        int i = 32;
        char[] buffer = new char[i];
        int targetBase= baseChars.Length;

        do
        {
            buffer[--i] = baseChars[value % targetBase];
            value = value / targetBase;
        }
        while (value > 0);

        char[] result = new char[32 - i];
        Array.Copy(buffer, i, result, 0, 32 - i);

        return new string(result);
    }
}

Update 2 (Performance Improvement)

Using an array buffer instead of string concatenation to build the result string gives a performance improvement especially on large number (see method IntToStringFast). In the best case (i.e. the longest possible input) this method is roughly three times faster. However, for 1-digit numbers (i.e. 1-digit in the target base), IntToString will be faster.

Something that can happen as well which throws this exception is the following. Say you have:

ko.applyBindings(myViewModel1, document.getElementById('element1'));
...
ko.applyBindings(myViewModel2, document.getElementById('element2'));

Now, when both #element1 and #element2 don't exist you'll get the error. The reason is that Knockout's applyBindings falls back on document.body as root element when #element1 and #element2 are not found. Now it tries to apply binding twice on the body...

Not a nice fallback of Knockout if you ask me. I'd rather have a clear error message that the element does not exist in the DOM (yet).

Hope this helps some people.

you should try this

~/Views/Shared/parts/UMFview.ascx

place the ~/Views/ before your code

this should work out,

      kable(dt) %>%
      kable_styling("striped") %>%
      add_header_above(c(" " = 1, "Group 1" = 2, "Group 2" = 2, "Group 3" = 2))
#OR
kable(dt) %>%
  kable_styling(c("striped", "bordered")) %>%
  add_header_above(c(" ", "Group 1" = 2, "Group 2" = 2, "Group 3" = 2)) %>%
  add_header_above(c(" ", "Group 4" = 4, "Group 5" = 2)) %>%
  add_header_above(c(" ", "Group 6" = 6))

for more you can check the link

cat file.txt | wc -l

According to the man page (for the BSD version, I don't have a GNU version to check):

If no files are specified, the standard input is used and no file name is displayed. The prompt will accept input until receiving EOF, or [^D] in most environments.

VMDK is a virtual disk file, what you need is a VMX file. Cruise on over to EasyVMX and have it create one for you, then just replace the VMDK file it gives you with the Cnrome OS one.

EasyVMX is good since VMWare Player has no VM creation stuff in it (at least in version 2, not sure about 3). You had to use one of VMWare's other products to do that.

All depends on the app you're trying to build. Use Windows if you're building a dialog based app. Use Pages if you're building a navigation based app. UserControls will be useful regardless of the direction you go as you can use them in both Windows and Pages.

Using Android studio 1.5.1 i got the following warnings:

Call requires API level 16 (current min is 9): android.view.View#setBackground

and the complaints about deprecation

'setBackgroundDrawable(android.graphics.drawable.Drawable)' is deprecated

Using this format, i got rid of both:

    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN) {
        //noinspection deprecation
        layout.setBackgroundDrawable(drawable);
    } else {
        layout.setBackground(drawable);
    }
