Programs & Examples On #Codewarrior

You can try to rename the python executable in the python3 folder to python3, that is if it was named python formally... it worked for me

The Main method is static inside the Program class. You can't call an instance method from inside a static method, which is why you're getting the error.

To fix it you just need to make your GetRandomBits() method static as well.

Just import the HttpModule and the HttpClientModule only:

import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';

No need for the HttpClient.

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

Overview of Scanner.hasNextXXX methods

java.util.Scanner has many hasNextXXX methods that can be used to validate input. Here's a brief overview of all of them:

• hasNext() - does it have any token at all?
• hasNextLine() - does it have another line of input?
• For Java primitives
  • hasNextInt() - does it have a token that can be parsed into an int?
  • Also available are hasNextDouble(), hasNextFloat(), hasNextByte(), hasNextShort(), hasNextLong(), and hasNextBoolean()
  • As bonus, there's also hasNextBigInteger() and hasNextBigDecimal()
  • The integral types also has overloads to specify radix (for e.g. hexadecimal)
• Regular expression-based
  • hasNext(String pattern)
  • hasNext(Pattern pattern) is the Pattern.compile overload

Scanner is capable of more, enabled by the fact that it's regex-based. One important feature is useDelimiter(String pattern), which lets you define what pattern separates your tokens. There are also find and skip methods that ignores delimiters.

The following discussion will keep the regex as simple as possible, so the focus remains on Scanner.

Example 1: Validating positive ints

Here's a simple example of using hasNextInt() to validate positive int from the input.

Scanner sc = new Scanner(System.in);
int number;
do {
    System.out.println("Please enter a positive number!");
    while (!sc.hasNextInt()) {
        System.out.println("That's not a number!");
        sc.next(); // this is important!
    }
    number = sc.nextInt();
} while (number <= 0);
System.out.println("Thank you! Got " + number);

Here's an example session:

Please enter a positive number!
five
That's not a number!
-3
Please enter a positive number!
5
Thank you! Got 5

Note how much easier Scanner.hasNextInt() is to use compared to the more verbose try/catch Integer.parseInt/NumberFormatException combo. By contract, a Scanner guarantees that if it hasNextInt(), then nextInt() will peacefully give you that int, and will not throw any NumberFormatException/InputMismatchException/NoSuchElementException.

Related questions

• How do I keep a scanner from throwing exceptions when the wrong type is entered? (java)

Example 2: Multiple hasNextXXX on the same token

Note that the snippet above contains a sc.next() statement to advance the Scanner until it hasNextInt(). It's important to realize that none of the hasNextXXX methods advance the Scanner past any input! You will find that if you omit this line from the snippet, then it'd go into an infinite loop on an invalid input!

This has two consequences:

• If you need to skip the "garbage" input that fails your hasNextXXX test, then you need to advance the Scanner one way or another (e.g. next(), nextLine(), skip, etc).
• If one hasNextXXX test fails, you can still test if it perhaps hasNextYYY!

Here's an example of performing multiple hasNextXXX tests.

Scanner sc = new Scanner(System.in);
while (!sc.hasNext("exit")) {
    System.out.println(
        sc.hasNextInt() ? "(int) " + sc.nextInt() :
        sc.hasNextLong() ? "(long) " + sc.nextLong() :  
        sc.hasNextDouble() ? "(double) " + sc.nextDouble() :
        sc.hasNextBoolean() ? "(boolean) " + sc.nextBoolean() :
        "(String) " + sc.next()
    );
}

Here's an example session:

5
(int) 5
false
(boolean) false
blah
(String) blah
1.1
(double) 1.1
100000000000
(long) 100000000000
exit

Note that the order of the tests matters. If a Scanner hasNextInt(), then it also hasNextLong(), but it's not necessarily true the other way around. More often than not you'd want to do the more specific test before the more general test.

Example 3 : Validating vowels

Scanner has many advanced features supported by regular expressions. Here's an example of using it to validate vowels.

Scanner sc = new Scanner(System.in);
System.out.println("Please enter a vowel, lowercase!");
while (!sc.hasNext("[aeiou]")) {
    System.out.println("That's not a vowel!");
    sc.next();
}
String vowel = sc.next();
System.out.println("Thank you! Got " + vowel);

Here's an example session:

Please enter a vowel, lowercase!
5
That's not a vowel!
z
That's not a vowel!
e
Thank you! Got e

In regex, as a Java string literal, the pattern "[aeiou]" is what is called a "character class"; it matches any of the letters a, e, i, o, u. Note that it's trivial to make the above test case-insensitive: just provide such regex pattern to the Scanner.

• java.util.regex.Pattern

Example 4: Using two Scanner at once

Sometimes you need to scan line-by-line, with multiple tokens on a line. The easiest way to accomplish this is to use two Scanner, where the second Scanner takes the nextLine() from the first Scanner as input. Here's an example:

Scanner sc = new Scanner(System.in);
System.out.println("Give me a bunch of numbers in a line (or 'exit')");
while (!sc.hasNext("exit")) {
    Scanner lineSc = new Scanner(sc.nextLine());
    int sum = 0;
    while (lineSc.hasNextInt()) {
        sum += lineSc.nextInt();
    }
    System.out.println("Sum is " + sum);
}

Here's an example session:

Give me a bunch of numbers in a line (or 'exit')
3 4 5
Sum is 12
10 100 a million dollar
Sum is 110
wait what?
Sum is 0
exit

In addition to Scanner(String) constructor, there's also Scanner(java.io.File) among others.

Summary

• Scanner provides a rich set of features, such as hasNextXXX methods for validation.
• Proper usage of hasNextXXX/nextXXX in combination means that a Scanner will NEVER throw an InputMismatchException/NoSuchElementException.
• Always remember that hasNextXXX does not advance the Scanner past any input.
• Don't be shy to create multiple Scanner if necessary. Two simple Scanner is often better than one overly complex Scanner.
• Finally, even if you don't have any plans to use the advanced regex features, do keep in mind which methods are regex-based and which aren't. Any Scanner method that takes a String pattern argument is regex-based.
  • Tip: an easy way to turn any String into a literal pattern is to Pattern.quote it.

.list-inline class in bootstrap is a Inline Unordered List.

If you want to create a horizontal menu using ordered or unordered list you need to place all list items in a single line i.e. side by side. You can do this by simply applying the class

<div class="list-inline">
    <a href="#" class="list-inline-item">First item</a>
    <a href="#" class="list-inline-item">Secound item</a>
    <a href="#" class="list-inline-item">Third item</a>
  </div>

EDIT: Starting Feb 1, 2014, Apple will no longer accept pre-iOS7 apps for submission to App Store. So while this technique still works, it will not be useful for most readers.

Yes, this is fine. I still build with iOS 4.3 for one project (it's been awhile since we updated; but they still accepted it after iOS 6 came out), and I currently build 10.5 apps with Xcode 5.

See How to point Xcode to an old SDK so it can be used as a "Base SDK"? for details on how to set it up. You can use my fix-xcode script to link everything for you every time you upgrade.

The only trick is getting the old SDKs. If you don't have them, you generally need to download old versions of Xcode (still available on developer.apple.com), open the installer package, and hunt around to find the SDK you need.

SDKs can be found within the installer package at:

Xcode.app/Contents/Developer/Platforms/

Also note that if you want to apply an instance method to an array, you need to pass the function as:

call_user_func_array(array($instance, "MethodName"), $myArgs);

I ran into this trying to revive an accidentally deleted Docker Container (oraclelinux's MySQL) from a luckily-not-removed docker volume that had the DB data in physical files.

So, all I wanted to do was to turn the data from physical files into a .sql importable file to recreate the container with the DB and the data.

I tried biolin's solution, but ran into some [InnoDB] Multiple files found for the same tablespace ID errors, after restart. I realized that doing open hurt surgery on certain folders/files there is quite trickey.

The solution that worked for me was temporarily changing the datadir= in my.cnf to the available folder and restarting the MySQL server. It did the job perfectly!

If you are on Eclipse,

Right click on your project folder under "Package Explorer".

Goto Source -> Clean up and choose your project.

This will cleanup any mess and your break-point should work now.

I think who the best mix for html & Css for quick and clean mod is :

        <td>2</td>
        <td>3</td>
        <td>4</td>
    </tr>

close the <table> init tag then copy where you want :) I hope it can be useful Have a good day w stackoverflow

p.s. Bootstrap v3.2.0

it has been a while but my answer may help someone:

if you already defined the relation properly you can use this:

        var res = query.Products.Select(m => new
        {
            productID = product.Id,
            categoryID = m.ProductCategory.Select(s => s.Category.ID).ToList(),
        }).ToList();

Code from the above answer by Dutchie432

.FixedHeightContainer {
    float:right;
    height: 250px;
    width:250px; 
    padding:3px; 
    background:#f00;
}

.Content {
    height:224px;
    overflow:auto;
    background:#fff;
}

That's known as an Arrow Function, part of the ECMAScript 2015 spec...

var foo = ['a', 'ab', 'abc'];_x000D_
_x000D_
var bar = foo.map(f => f.length);_x000D_
_x000D_
console.log(bar); // 1,2,3

Shorter syntax than the previous:

// < ES6:_x000D_
var foo = ['a', 'ab', 'abc'];_x000D_
_x000D_
var bar = foo.map(function(f) {_x000D_
  return f.length;_x000D_
});_x000D_
console.log(bar); // 1,2,3

DEMO

The other awesome thing is lexical this... Usually, you'd do something like:

function Foo() {_x000D_
  this.name = name;_x000D_
  this.count = 0;_x000D_
  this.startCounting();_x000D_
}_x000D_
_x000D_
Foo.prototype.startCounting = function() {_x000D_
  var self = this;_x000D_
  setInterval(function() {_x000D_
    // this is the Window, not Foo {}, as you might expect_x000D_
    console.log(this); // [object Window]_x000D_
    // that's why we reassign this to self before setInterval()_x000D_
    console.log(self.count);_x000D_
    self.count++;_x000D_
  }, 1000)_x000D_
}_x000D_
_x000D_
new Foo();

But that could be rewritten with the arrow like this:

function Foo() {_x000D_
  this.name = name;_x000D_
  this.count = 0;_x000D_
  this.startCounting();_x000D_
}_x000D_
_x000D_
Foo.prototype.startCounting = function() {_x000D_
  setInterval(() => {_x000D_
    console.log(this); // [object Object]_x000D_
    console.log(this.count); // 1, 2, 3_x000D_
    this.count++;_x000D_
  }, 1000)_x000D_
}_x000D_
_x000D_
new Foo();

For more, here's a pretty good answer for when to use arrow functions.

Since dplyr 1.0.0, the slice_max()/slice_min() functions were implemented:

The documentation on with_ties parameter:

Should ties be kept together? The default, TRUE, may return more rows than you request. Use FALSE to ignore ties, and return the first n rows.

Sure:

var query = grades.GroupBy(student => student.Name)
                  .Select(group => 
                        new { Name = group.Key,
                              Students = group.OrderByDescending(x => x.Grade) })
                  .OrderBy(group => group.Students.First().Grade);

Note that you can get away with just taking the first grade within each group after ordering, because you already know the first entry will be have the highest grade.

Then you could display them with:

foreach (var group in query)
{
    Console.WriteLine("Group: {0}", group.Name);
    foreach (var student in group.Students)
    {
        Console.WriteLine("  {0}", student.Grade);
    }
}

Mac OS: You have to install ChromeDriver first:

brew cask install chromedriver

It will be copied to /usr/local/bin/chromedriver. Then you can use it in java code classes.

Based on the @AndrewCox 's answer with some minor improvements:

from http.client import HTTPSConnection
from base64 import b64encode


client = HTTPSConnection("www.google.com")
user = "user_name"
password = "password"
headers = {
    "Authorization": "Basic {}".format(
        b64encode(bytes(f"{user}:{password}", "utf-8")).decode("ascii")
    )
}
client.request('GET', '/', headers=headers)
res = client.getresponse()
data = res.read()

Note, you should set encoding if you use bytes function instead of b"".

The first is a much better option.

Parallel.ForEach, internally, uses a Partitioner<T> to distribute your collection into work items. It will not do one task per item, but rather batch this to lower the overhead involved.

The second option will schedule a single Task per item in your collection. While the results will be (nearly) the same, this will introduce far more overhead than necessary, especially for large collections, and cause the overall runtimes to be slower.

FYI - The Partitioner used can be controlled by using the appropriate overloads to Parallel.ForEach, if so desired. For details, see Custom Partitioners on MSDN.

The main difference, at runtime, is the second will act asynchronous. This can be duplicated using Parallel.ForEach by doing:

Task.Factory.StartNew( () => Parallel.ForEach<Item>(items, item => DoSomething(item)));

By doing this, you still take advantage of the partitioners, but don't block until the operation is complete.

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.

If you don't want word wrap, assign the CSS style white-space: nowrap to the cells.

Besides the usual recommendation:

1. Drop index for bulk insert.
2. Batch inserts/updates in large transactions.
3. Tune your buffer cache/disable journal /w PRAGMAs.
4. Use a 64bit machine (to be able to use lots of cache™).
5. [added July 2014] Use common table expression (CTE) instead of running multiple SQL queries! Requires SQLite release 3.8.3.

I have learnt the following from my experience with SQLite3:

1. For maximum insert speed, don't use schema with any column constraint. (Alter table later as needed You can't add constraints with ALTER TABLE).
2. Optimize your schema to store what you need. Sometimes this means breaking down tables and/or even compressing/transforming your data before inserting to the database. A great example is to storing IP addresses as (long) integers.
3. One table per db file - to minimize lock contention. (Use ATTACH DATABASE if you want to have a single connection object.
4. SQLite can store different types of data in the same column (dynamic typing), use that to your advantage.

Question/comment welcome. ;-)

drop procedure if exists doWhile;
DELIMITER //  
CREATE PROCEDURE doWhile()   
BEGIN
DECLARE i INT DEFAULT 2376921001; 
WHILE (i <= 237692200) DO
    INSERT INTO `mytable` (code, active, total) values (i, 1, 1);
    SET i = i+1;
END WHILE;
END;
//  

CALL doWhile(); 

You should create a static factory method which takes single argument and annotate it with @JsonCreator (available since Jackson 1.2)

@JsonCreator
public static Event forValue(String value) { ... }

Read more about JsonCreator annotation here.

You should use POST if there is a lot of data, or sort-of sensitive information (really sensitive stuff needs a secure connection as well).

Use GET if you want people to be able to bookmark your page, because all the data is included with the bookmark.

Just be careful of people hitting REFRESH with the GET method, because the data will be sent again every time without warning the user (POST sometimes warns the user about resending data).

I get your problem, I faced the same problem in my Application. I was calling registerReceiver() multiple time within the application.

A simple solution to this problem is to call the registerReceiver() in your Custom Application Class. This will ensure that your Broadcast receiver will be called only one in your entire Application lifecycle.

public class YourApplication extends Application
{
    @Override
    public void onCreate()
    {
        super.onCreate();

        //register your Broadcast receiver here
        IntentFilter intentFilter = new IntentFilter("MANUAL_BROADCAST_RECIEVER");
        registerReceiver(new BroadcastReciever(), intentFilter);

    }
}

Specifying auto on width and height elements is the same as removing them, technically. Using vanilla Javascript:

images[i].style.height = "auto";
images[i].style.width = "auto";

Solution tested with https://httpbin.org/ and inline bash script
1. For variables without spaces in it i.e. 1:
Simply add ' before and after $variable when replacing desired string

for i in {1..3}; do \
  curl -X POST -H "Content-Type: application/json" -d \
    '{"number":"'$i'"}' "https://httpbin.org/post"; \
done

2. For input with spaces:
Wrap variable with additional " i.e. "el a":

declare -a arr=("el a" "el b" "el c"); for i in "${arr[@]}"; do \
  curl -X POST -H "Content-Type: application/json" -d \
    '{"elem":"'"$i"'"}' "https://httpbin.org/post"; \
done

Wow works :)

Yes, you can definitely do this. Just use something like

.parent:hover .child {
   /* ... */
}

According to this page it's supported by all major browsers.

The keyword global is only useful to change or create global variables in a local context, although creating global variables is seldom considered a good solution.

def bob():
    me = "locally defined"    # Defined only in local context
    print(me)

bob()
print(me)     # Asking for a global variable

The above will give you:

locally defined
Traceback (most recent call last):
  File "file.py", line 9, in <module>
    print(me)
NameError: name 'me' is not defined

While if you use the global statement, the variable will become available "outside" the scope of the function, effectively becoming a global variable.

def bob():
    global me
    me = "locally defined"   # Defined locally but declared as global
    print(me)

bob()
print(me)     # Asking for a global variable

So the above code will give you:

locally defined
locally defined

In addition, due to the nature of python, you could also use global to declare functions, classes or other objects in a local context. Although I would advise against it since it causes nightmares if something goes wrong or needs debugging.

Agreed with jcadcell comments, but had to use JDK 1.8 because my eclipse need that. So I just copied the MSVCR71.DLL from jdk1.6 and pasted into jdk1.8 in both the folder jdk1.8.0_121\bin and jdk1.8.0_121\jre\bin

and it Worked .... Wow... Thanks :)

Dispose(true);
GC.SuppressFinalize(this);

If object has finalizer, .net put a reference in finalization queue.

Since we have call Dispose(ture), it clear object, so we don't need finalization queue to do this job.

So call GC.SuppressFinalize(this) remove reference in finalization queue.

If you're using Brunch, the plugin Constangular helps you to manage variables for different environments.

I found when i used this there was a problem when d1 fell on saturday. Below is what i used to correct this.

declare @d1 datetime, @d2 datetime
select @d1 = '11/19/2011' ,  @d2 = '11/28/2011'

select datediff(dd, @d1, @d2) +case when datepart(dw, @d1) = 7 then 1 else 0 end - (datediff(wk, @d1, @d2) * 2) -
 case when datepart(dw, @d1) = 1 then 1 else 0 end +
 case when datepart(dw, @d2) = 1 then 1 else 0 end

/^[a-z]{0,10}$/ should work. /^[a-z]{1,10}$/ if you want to match at least one character, like /^[a-z]+$/ does.

A bit late to the party, but JQuery change inner text but preserve html has at least one approach not mentioned here:

var $td = $("#demoTable td");
$td.html($td.html().replace('Tap on APN and Enter', 'new text'));

Without fixing the text, you could use (snother)[https://stackoverflow.com/a/37828788/1587329]:

var $a = $('#demoTable td');
var inner = '';
$a.children.html().each(function() {
    inner = inner + this.outerHTML;
});
$a.html('New text' + inner);

I had the same problem as you.

I did git status git fetch git pull, but my branch was still behind to origin. I had folders and files pushed to remote and I saw the files on the web, but on my local they were missing.

Finally, these commands updated all the files and folders on my local:

git fetch --all
git reset --hard origin/master 

or if you want a branch

git checkout your_branch_name_here
git reset --hard origin/your_branch_name_here

How about this solution?

It doesn't use the Thread class, but it IS concurrent, and in a way it does exactly what you request

ExecutorService pool = Executors.newFixedThreadPool(2); // creates a pool of threads for the Future to draw from

Future<Integer> value = pool.submit(new Callable<Integer>() {
    @Override
    public Integer call() {return 2;}
});

Now all you do is say value.get() whenever you need to grab your returned value, the thread is started the very second you give value a value so you don't ever have to say threadName.start() on it.

What a Future is, is a promise to the program, you promise the program that you'll get it the value it needs sometime in the near future

If you call .get() on it before it's done, the thread that's calling it will simply just wait until it's done

Just try this, it explains it pretty much itself. You can't create a view with an ORDER BY except if...

CREATE VIEW v_Test
         AS
           SELECT name
             FROM sysobjects
         ORDER BY name
        GO

Msg 1033, Level 15, State 1, Procedure TestView, Line 5 The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.

Some tips to be found in Xcode Tools Tips.

I know this is an old question.

Here's another option - attending to different platform requirements - Source

<link rel='shortcut icon' type='image/vnd.microsoft.icon' href='/favicon.ico'> <!-- IE -->
<link rel='apple-touch-icon' type='image/png' href='/icon.57.png'> <!-- iPhone -->
<link rel='apple-touch-icon' type='image/png' sizes='72x72' href='/icon.72.png'> <!-- iPad -->
<link rel='apple-touch-icon' type='image/png' sizes='114x114' href='/icon.114.png'> <!-- iPhone4 -->
<link rel='icon' type='image/png' href='/icon.114.png'> <!-- Opera Speed Dial, at least 144×114 px -->

This is the broadest approach I have found so far.

Ultimately the decision depends on your own needs. Ask yourself, who is your target audience?

UPDATE May 27, 2018: As expected, time goes by and things change. But there's good news too. I found a tool called Real Favicon Generator that generates all the required lines for the icon to work on all modern browsers and platforms. It doesn't handle backwards compatibility though.

Google shrinks their css classes etc., so it is not easy to identify everything.

Also you have the problem that you have to "wait" until the site shows the result. I would do it like this:

public static void main(String[] args) {

    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    WebElement element = driver.findElement(By.name("q"));
    element.sendKeys("Cheese!\n"); // send also a "\n"
    element.submit();

    // wait until the google page shows the result
    WebElement myDynamicElement = (new WebDriverWait(driver, 10))
              .until(ExpectedConditions.presenceOfElementLocated(By.id("resultStats")));

    List<WebElement> findElements = driver.findElements(By.xpath("//*[@id='rso']//h3/a"));

    // this are all the links you like to visit
    for (WebElement webElement : findElements)
    {
        System.out.println(webElement.getAttribute("href"));
    }
}

This will print you:

• http://de.wikipedia.org/wiki/Cheese
• http://en.wikipedia.org/wiki/Cheese
• http://www.dict.cc/englisch-deutsch/cheese.html
• http://www.cheese.com/
• http://projects.gnome.org/cheese/

This error can occur if you project is compiling with JDK 1.6 and you have dependencies compiled with Java 7.

I think in your Angular-2 version directives are not supported in Component decorator, hence you have to register directive same as other component in @NgModule and then import in component as below and also remove directives: [ChildComponent] from decorator.

import {myDirective} from './myDirective';

after_initialize method is deprecated, use the callback instead.

after_initialize :defaults

def defaults
  self.extras||={}
  self.other_stuff||="This stuff"
end

however, using :default in your migrations is still the cleanest way.

To play an Audio file in the Windows form using C# let's check simple example as follows :

1.Go Visual Studio(VS-2008/2010/2012) --> File Menu --> click New Project.

2.In the New Project --> click Windows Forms Application --> Give Name and then click OK.

A new "Windows Forms" project will opens.

3.Drag-and-Drop a Button control from the Toolbox to the Windows Form.

4.Double-click the button to create automatically the default Click event handler, and add the following code.

This code displays the File Open dialog box and passes the results to a method named "playSound" that you will create in the next step.

 OpenFileDialog dialog = new OpenFileDialog();
 dialog.Filter = "Audio Files (.wav)|*.wav";


if(dialog.ShowDialog() == DialogResult.OK)
{
  string path = dialog.FileName;
  playSound(path);
}

5.Add the following method code under the button1_Click event hander.

 private void playSound(string path)
 {
   System.Media.SoundPlayer player = new System.Media.SoundPlayer();
   player.SoundLocation = path;
   player.Load();
   player.Play();
 }

6.Now let's run the application just by Pressing the F5 to run the code.

7.Click the button and select an audio file. After the file loads, the sound will play.

I hope this is useful example to beginners...

Once I packed JS code doing that to a tiny library:

https://github.com/AlexLibs/client-side-csv-generator

The Code, Documentation and Demo/Playground are provided on Github.

You could use something like this. ReactDom is for react.14. Just React otherwise.

    componentDidUpdate = () => { ReactDom.findDOMNode(this).scrollIntoView(); }

Update 5/11/2019 for React 16+

  constructor(props) {_x000D_
    super(props)_x000D_
    this.childDiv = React.createRef()_x000D_
  }_x000D_
_x000D_
  componentDidMount = () => this.handleScroll()_x000D_
_x000D_
  componentDidUpdate = () => this.handleScroll()_x000D_
_x000D_
  handleScroll = () => {_x000D_
    const { index, selected } = this.props_x000D_
    if (index === selected) {_x000D_
      setTimeout(() => {_x000D_
        this.childDiv.current.scrollIntoView({ behavior: 'smooth' })_x000D_
      }, 500)_x000D_
    }_x000D_
  }

Well, since your on a shared server, you can't do anything about it. They usually set the max execution time so that you can't override it. I suggest you contact them.

Just a small addition to Jeff Bowman's excellent answer, as I found this question when searching for a solution to one of my own problems:

If a call to a method matches more than one mock's when trained calls, the order of the when calls is important, and should be from the most wider to the most specific. Starting from one of Jeff's examples:

when(foo.quux(anyInt(), anyInt())).thenReturn(true);
when(foo.quux(anyInt(), eq(5))).thenReturn(false);

is the order that ensures the (probably) desired result:

foo.quux(3 /*any int*/, 8 /*any other int than 5*/) //returns true
foo.quux(2 /*any int*/, 5) //returns false

If you inverse the when calls then the result would always be true.

The solution of creating a new HTML file with HTML (Web Forms) Designer worked for that file but not for other, individual HTML files that I wanted to edit.

I did find the Open With option in the Open File dialogue and was able to select the HTML (Web Forms) Editor there. Having clicked the "Set as Default" option in that window, VS then remembered to use that editor when I opened other HTML files.

Sorry to rouse a really old thread, but I've been using jemdoc for a couple of years and it is really excellent.

Try a slight different approach:

//set string and append it as object
var myHtmlString = '<iframe id="myFrame" width="854" height="480" src="http://www.youtube.com/embed/gYKqrjq5IjU?feature=oembed" frameborder="0" allowfullscreen></iframe>';
$('body').append(myHtmlString);

//as you noticed you can't just get it back
var myHtmlStringBack = $('#myFrame').html(); 
alert(myHtmlStringBack); // will be empty (a bug in jquery?) but...

//since an id was added to your iframe so you can retrieve its attributes back...
var width = $('#myFrame').attr('width');
var height = $('#myFrame').attr('height');
var src = $('#myFrame').attr('src');
var myReconstructedString = '<iframe id="myFrame" width="'+ width +'" height="'+ height +'" src="'+ src+'" frameborder="0" allowfullscreen></iframe>';
alert(myReconstructedString);

Just declare a variable like k or m or any other you want, now just add this piece of code at the end of your program

k=input("press close to exit") 

Here I just assumed k as variable to pause the program, you can use any variable you like.

When an iFrame loads, it initially contains the #document, so checking the load state might best work by checking what's there now..

if ($('iframe').contents().find('body').children().length > 0) {
    // is loaded
} else {
    // is not loaded
}

new[,2] is a factor, not a numeric vector. Transform it first

new$MY_NEW_COLUMN <-as.numeric(as.character(new[,2])) * 5

SELECT ID, Col1, Col2, Col3, 
    (SELECT MIN(Col) FROM (VALUES (Col1), (Col2), (Col3)) AS X(Col)) AS TheMin
FROM Table

The better option would be to just use the resource returned array as an array, meaning :

getResources().getStringArray(R.array.your_array)[position]

This is a shortcut approach of above mentioned approaches but does the work in the fashion you want. Otherwise android doesnt provides direct XML indexing for xml based arrays.

Please try window.onbeforeunload instead for window.onunload for chrome. You can also try calling onbeforeunload from the body> tag which might work in chrome.

However, we do have a problem with unload function in chrome browser. please check

location.href does not work in chrome when called through the body/window unload event

It crashed for me because one of fields in my activity id was matching with id in an other activity. I fixed it by giving a unique id.

In my loginActivity.xml password field id was "password". In my registration activity I just fixed it by giving id r_password, then it returned not null object:

password = (EditText)findViewById(R.id.r_password);

Try adding the header file to your project's files. (right click on project -> add existing file).

The error tells you that there is an error but you don´t catch it. This is how you can catch it:

getAllPosts().then(response => {
    console.log(response);
}).catch(e => {
    console.log(e);
});

You can also just put a console.log(reponse) at the beginning of your API callback function, there is definitely an error message from the Graph API in it.

More information: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch

Or with async/await:

//some async function
try {
    let response = await getAllPosts();
} catch(e) {
    console.log(e);
}

If you just want to scroll, you could use jQuery's scrollTop method. http://docs.jquery.com/CSS/scrollTop

var table = jQuery( 'table' );
table.scrollTop( table.find( 'tr:last' ).scrollTop() );

Something like that maybe?

Add a $event to the ng-click, for example:

<button type="button" ng-click="saveOffer($event)" accesskey="S"></button>

Then the jQuery.Event was passed to the callback:

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/getYear

getYear is no longer used and has been replaced by the getFullYear method.

The getYear method returns the year minus 1900; thus:

• For years greater than or equal to 2000, the value returned by getYear is 100 or greater. For example, if the year is 2026, getYear returns 126.
• For years between and including 1900 and 1999, the value returned by getYear is between 0 and 99. For example, if the year is 1976, getYear returns 76.
• For years less than 1900, the value returned by getYear is less than 0. For example, if the year is 1800, getYear returns -100.
• To take into account years before and after 2000, you should use getFullYear instead of getYear so that the year is specified in full.

I just made my own UniqueList in my own little library like this:

package com.bprog.collections;//my own little set of useful utilities and classes

import java.util.HashSet;
import java.util.ArrayList;
import java.util.List;
/**
*
* @author Jonathan
*/
public class UniqueList {

private HashSet masterSet = new HashSet();
private ArrayList growableUniques;
private Object[] returnable;

public UniqueList() {
    growableUniques = new ArrayList();
}

public UniqueList(int size) {
    growableUniques = new ArrayList(size);
}

public void add(Object thing) {
    if (!masterSet.contains(thing)) {
        masterSet.add(thing);
        growableUniques.add(thing);
    }
}

/**
 * Casts to an ArrayList of unique values
 * @return 
 */
public List getList(){
    return growableUniques;
}

public Object get(int index) {
    return growableUniques.get(index);
}

public Object[] toObjectArray() {
    int size = growableUniques.size();
    returnable = new Object[size];
    for (int i = 0; i < size; i++) {
        returnable[i] = growableUniques.get(i);
    }
    return returnable;
    }
}

I have a TestCollections class that looks like this:

package com.bprog.collections;
import com.bprog.out.Out;
/**
*
* @author Jonathan
*/
public class TestCollections {
    public static void main(String[] args){
        UniqueList ul = new UniqueList();
        ul.add("Test");
        ul.add("Test");
        ul.add("Not a copy");
        ul.add("Test"); 
        //should only contain two things
        Object[] content = ul.toObjectArray();
        Out.pl("Array Content",content);
    }
}

Works fine. All it does is it adds to a set if it does not have it already and there's an Arraylist that is returnable, as well as an object array.

If you want to extend the amount of time permitted for an ASP.NET script to execute then increase the Server.ScriptTimeout value. The default is 90 seconds for .NET 1.x and 110 seconds for .NET 2.0 and later.

For example:

// Increase script timeout for current page to five minutes
Server.ScriptTimeout = 300;

This value can also be configured in your web.config file in the httpRuntime configuration element:

<!-- Increase script timeout to five minutes -->
<httpRuntime executionTimeout="300" 
  ... other configuration attributes ...
/>

Please note according to the MSDN documentation:

"This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging."

If you've already done this but are finding that your session is expiring then increase the ASP.NET HttpSessionState.Timeout value:

For example:

// Increase session timeout to thirty minutes
Session.Timeout = 30;

This value can also be configured in your web.config file in the sessionState configuration element:

<configuration>
  <system.web>
    <sessionState 
      mode="InProc"
      cookieless="true"
      timeout="30" />
  </system.web>
</configuration>

If your script is taking several minutes to execute and there are many concurrent users then consider changing the page to an Asynchronous Page. This will increase the scalability of your application.

The other alternative, if you have administrator access to the server, is to consider this long running operation as a candidate for implementing as a scheduled task or a windows service.

just discovered enumeratum. it's pretty amazing and equally amazing it's not more well known!

In Python, You can Try...

from encodings.aliases import aliases
alias_values = set(aliases.values())

for encoding in set(aliases.values()):
    try:
        df=pd.read_csv("test.csv", encoding=encoding)
        print('successful', encoding)
    except:
        pass

Is there any other way to convert that array into string ?

Yes there is. serialize(). It can convert various data types (including object and arrays) into a string representation which you can unserialize() at a later time. Serializing an associative array such as Array(18 => 'Somthing') will preserve both keys and values:

<?php
$a = array(18 => 'Something');
echo serialize($a);                                   // a:1:{i:18;s:9:"Something";}
var_dump(unserialize('a:1:{i:18;s:9:"Something";}')); // array(1) {
                                                      //   [18]=>
                                                      //   string(9) "Something"
                                                      // }

Starting a service:

adb shell am startservice ...

start a Service. Options are: --user | current: Specify which user to run as; if not specified then run as the current user.

Stopping a service:

adb shell am stopservice ... 

stop a Service. Options are: --user | current: Specify which user to run as; if not specified then run as the current user.

I'm really late to party here, but most of the answers seem to be about the whys and whens of using assertions in general, rather than using AssertionError in particular.

assert and throw new AssertionError() are very similar and serve the same conceptual purpose, but there are differences.

1. throw new AssertionError() will throw the exception regardless of whether assertions are enabled for the jvm (i.e., through the -ea switch).
2. The compiler knows that throw new AssertionError() will exit the block, so using it will let you avoid certain compiler errors that assert will not.

For example:

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            throw new AssertionError();
        }
        System.out.println("n = " + n);
    }

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            assert false;
        }
        System.out.println("n = " + n);
    }

The first block, above, compiles just fine. The second block does not compile, because the compiler cannot guarantee that n has been initialized by the time the code tries to print it out.

This topic is somewhat outdated, but my solution to the missing Test status in VS2015:

The task-status only shows up on the Debug buildconfiguration. Ofcourse this also makes it impossible to debug your test through the test-explorer.

Here is my platform specific code(unix)

public static List<File> findFiles(String dir, String... names)
    {
        LinkedList<String> command = new LinkedList<String>();
        command.add("/usr/bin/find");
        command.add(dir);
        List<File> result = new LinkedList<File>();
        if (names.length > 1)
            {
                List<String> newNames = new LinkedList<String>(Arrays.asList(names));
                String first = newNames.remove(0);
                command.add("-name");
                command.add(first);
                for (String newName : newNames)
                    {
                        command.add("-or");
                        command.add("-name");
                        command.add(newName);
                    }
            }
        else if (names.length > 0)
            {
                command.add("-name");
                command.add(names[0]);
            }
        try
            {
                ProcessBuilder pb = new ProcessBuilder(command);
                Process p = pb.start();
                p.waitFor();
                InputStream is = p.getInputStream();
                InputStreamReader isr = new InputStreamReader(is);
                BufferedReader br = new BufferedReader(isr);

                    {
                        // System.err.println(line);
                        result.add(new File(line));
                    }
                p.destroy();
            }
        catch (Exception e)
            {
                e.printStackTrace();

You can't do compareAndSet, getAndSet as atomic operation with volatile boolean (unless of course you synchronize it).

Firstly, the Instagram API endpoint "tags" required OAuth authentication.

You can query results for a particular hashtag (snowy in this case) using the following url

It is rate limited to 5000 (X-Ratelimit-Limit:5000) per hour

https://api.instagram.com/v1/tags/snowy/media/recent

You can play around here :

You need to use "Authentication" as OAuth 2 and will be prompted to signin via Instagram. Post that you might have to reneter the "tag-name" in "Template" section.

All the pagination related data is available in the "pagination" parameter in the response and use it's "next_url" to query for the next set of result.

Do the build job on Jenkins first without Sonar configured. Then add Sonar, and run a build job again. Should fix the problem

Yes, reload the css tag. And remember to make the new url unique (usually by appending a random query parameter). I have code to do this but not with me right now. Will edit later...

edit: too late... harto and nickf beat me to it ;-)

I tested this one and it works

// Map from firestore
// Using flutterfire package hence the returned data()
Map<String, dynamic> data = documentSnapshot.data();
DateTime _timestamp = data['timestamp'].toDate();

public String getIMEI(Context context){

    TelephonyManager mngr = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE); 
    String imei = mngr.getDeviceId();
    return imei;

}

I'd just like to add to Jon's example. To get a reference to your own assembly, you can use:

Assembly myAssembly = Assembly.GetExecutingAssembly();

System.Reflection namespace.

If you want to examine an assembly that you have no reference to, you can use either of these:

Assembly assembly = Assembly.ReflectionOnlyLoad(fullAssemblyName);
Assembly assembly = Assembly.ReflectionOnlyLoadFrom(fileName);

If you intend to instantiate your type once you've found it:

Assembly assembly = Assembly.Load(fullAssemblyName);
Assembly assembly = Assembly.LoadFrom(fileName);

See the Assembly class documentation for more information.

Once you have the reference to the Assembly object, you can use assembly.GetTypes() like Jon already demonstrated.

If the folder is accessible from the browser (not outside the document root of your web server), then you just need to output links to the locations of those files. If they are outside the document root, you will need to have links, buttons, whatever, that point to a PHP script that handles getting the files from their location and streaming to the response.

For security reasons you must avoid providing password on a command line otherwise anyone running ps command can see your password. Better to use sshpass utility like this:

#!/bin/bash

export SSHPASS="your-password"
sshpass -e ssh -oBatchMode=no sshUser@remoteHost

You might be interested in How to run the sftp command with a password from Bash script?

As others have noted, you can't have immutable arrays in Java.

If you absolutely need a method that returns an array that doesn't influence the original array, then you'd need to clone the array each time:

public int[] getFooArray() {
  return fooArray == null ? null : fooArray.clone();
}

Obviously this is rather expensive (as you'll create a full copy each time you call the getter), but if you can't change the interface (to use a List for example) and can't risk the client changing your internals, then it may be necessary.

This technique is called making a defensive copy.

 LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.text_entry, null);
//text_entry is an Layout XML file containing two text field to display in alert dialog
final EditText input1 = (EditText) textEntryView.findViewById(R.id.EditText1);
final EditText input2 = (EditText) textEntryView.findViewById(R.id.EditText2);             
input1.setText("DefaultValue", TextView.BufferType.EDITABLE);
input2.setText("DefaultValue", TextView.BufferType.EDITABLE);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);

alert.setIcon(R.drawable.icon)
     .setTitle("Enter the Text:")
     .setView(textEntryView)
     .setPositiveButton("Save", 
         new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int whichButton) {
                    Log.i("AlertDialog","TextEntry 1 Entered "+input1.getText().toString());
                    Log.i("AlertDialog","TextEntry 2 Entered "+input2.getText().toString());
                    /* User clicked OK so do some stuff */
             }
         })
     .setNegativeButton("Cancel",
         new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog,
                    int whichButton) {
             }
         });
alert.show();

You can create an extension method

static class MyExtensions
{
    internal static string Repeat(this char c, int n)
    {
        return new string(c, n);
    }
}

Then you can use it like this

Console.WriteLine('\t'.Repeat(10));

In Eclipse Ganymede (Subclipse)

Select project/file that contains bad change, and from pop-up menu choose:

Team -> Show History

Revisions related to that project/file will be shown in History tab.

Find revision where "bad changes" were committed and from pop-up menu choose:

Revert Changes from Revision X

This will merge changes in file(s) modified within bad revision, with revision prior to bad revision.

There are two scenarios from here:

1. If you committed no changes for that file (bad revision is last revision for that file), it will simply remove changes made in bad revision. Those changes are merged to your working copy so you have to commit them.

2. If you committed some changes for that file (bad revision is not last revision for that file), you will have to manually resolve conflict. Let say that you have file readme.txt with, and bad revision number is 33. Also, you've made another commit for that file in revision 34. After you choose Revert Changes from Revision 33 you will have following in your working copy:

readme.txt.merge-left.r33 - bad revision

readme.txt.merge-right.r32 - before bad revision

readme.txt.working - working copy version (same as in r34 if you don't have any uncommitted changes)

Original readme.txt will be marked conflicted, and will contain merged version (where changes from bad revision are removed) with some markers (<<<<<<< .working etc). If you just want to remove changes from bad revision and keep changes made after that, then all you have to do is remove markers. Otherwise, you can copy contents from one of 3 files mentioned above to original file. Whatever you choose, when you are done, mark conflict resolved by

Team - Mark Resolved

Temporary files will be removed and your file will be marked changed. As in 1, you have to commit changes.

Note that this does not remove revision from revision history in svn repository. You simply made new revision where changes from bad revision are removed.

As described by Crist Clark.

CLOSE_WAIT means that the local end of the connection has received a FIN from the other end, but the OS is waiting for the program at the local end to actually close its connection.

The problem is your program running on the local machine is not closing the socket. It is not a TCP tuning issue. A connection can (and quite correctly) stay in CLOSE_WAIT forever while the program holds the connection open.

Once the local program closes the socket, the OS can send the FIN to the remote end which transitions you to LAST_ACK while you wait for the ACK of the FIN. Once that is received, the connection is finished and drops from the connection table (if your end is in CLOSE_WAIT you do not end up in the TIME_WAIT state).

A couple of years ago, we got a report that one of our web apps wasn't displaying correctly in Firefox. It turned out that the page contained a tag that looked like

<div style="..." ... style="...">

When faced with a repeated style attribute, IE combines both of the styles, while Firefox only uses one of them, hence the different behavior. I changed the tag to

<div style="...; ..." ...>

and sure enough, it fixed the problem! The moral of the story is that browsers have more consistent handling of valid HTML than of invalid HTML. So, fix your damn markup already! (Or use HTML Tidy to fix it.)

Since Java 1.7 you can use Objects.equals:

java.util.Objects.equals(oneInteger, anotherInteger);

Returns true if the arguments are equal to each other and false otherwise. Consequently, if both arguments are null, true is returned and if exactly one argument is null, false is returned. Otherwise, equality is determined by using the equals method of the first argument.

Short of actually performing the merge in a throw away fashion (see Kasapo's answer), there doesn't seem to be a reliable way of seeing this.

Having said that, here's a method that comes marginally close:

git log TARGET_BRANCH...SOURCE_BRANCH --cherry

This gives a fair indication of which commits will make it into the merge. To see diffs, add -p. To see file names, add any of --raw, --stat, --name-only, --name-status.

The problem with the git diff TARGET_BRANCH...SOURCE_BRANCH approach (see Jan Hudec's answer) is, you'll see diffs for changes already in your target branch if your source branch contains cross merges.

It is very hard set caret in proper position when you have advance element like (p) (span) etc. The goal is to get (object text):

<div id="editable" contenteditable="true">dddddddddddddddddddddddddddd<p>dd</p>psss<p>dd</p>
    <p>dd</p>
    <p>text text text</p>
</div>
<p id='we'></p>
<button onclick="set_mouse()">focus</button>
<script>

    function set_mouse() {
        var as = document.getElementById("editable");
        el = as.childNodes[1].childNodes[0];//goal is to get ('we') id to write (object Text) because it work only in object text
        var range = document.createRange();
        var sel = window.getSelection();
        range.setStart(el, 1);
        range.collapse(true);
        sel.removeAllRanges();
        sel.addRange(range);

        document.getElementById("we").innerHTML = el;// see out put of we id
    }
</script>

You have to create an item of type ListBoxItem and add that to the Items collection:

list.Items.add( new ListBoxItem("clan", "sifOsoba"));

In short, on MariaDB

1) sudo mysql -u root;
2) use mysql;
3) UPDATE mysql.user SET plugin = 'mysql_native_password', 
      Password = PASSWORD('pass1234') WHERE User = 'root';
4) FLUSH PRIVILEGES;
5) exit;

A comparison between the different Visual Studio Express editions can be found at Visual Studio Express (archive.org link). The difference between Windows and Windows Desktop is that with the Windows edition you can build Windows Store Apps (using .NET, WPF/XAML) while the Windows Desktop edition allows you to write classic Windows Desktop applications. It is possible to install both products on the same machine.

Visual Studio Express 2010 allows you to build Windows Desktop applications. Writing Windows Store applications is not possible with this product.

For learning I would suggest Notepad and the command line. While an IDE provides significant productivity enhancements to professionals, it can be intimidating to a beginner. If you want to use an IDE nevertheless I would recommend Visual Studio Express 2013 for Windows Desktop.

See http://www.danielmoth.com/Blog/mscorlibdll.aspx and What does 'Cor' stand for?

Use StringBuilder:

String str;
Char a, b, c;
a = 'i';
b = 'c';
c = 'e';

StringBuilder sb = new StringBuilder();
sb.append(a);
sb.append(b);
sb.append(c);
str = sb.toString();

One-liner:

new StringBuilder().append(a).append(b).append(c).toString();

Doing ""+a+b+c gives:

new StringBuilder().append("").append(a).append(b).append(c).toString();

I asked some time ago related question.

From the documentation, you can apparently use either command to keep the file in the project history. Looks like you want remove, since it also deletes the file from the working directory.

From the Mercurial book at http://hgbook.red-bean.com/read/:

Removing a file does not affect its history. It is important to understand that removing a file has only two effects. It removes the current version of the file from the working directory. It stops Mercurial from tracking changes to the file, from the time of the next commit. Removing a file does not in any way alter the history of the file.

The man page hg(1) says this about forget:

Mark the specified files so they will no longer be tracked after the next commit. This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.

And this about remove:

Schedule the indicated files for removal from the repository. This only removes files from the current branch, not from the entire project history.

All in python (using psycopg2), create the empty table first then use copy_expert to load the csv into it. It should handle for empty values.

import psycopg2
conn = psycopg2.connect(host="hosturl", database="db_name", user="username", password="password")
cur = conn.cursor()
cur.execute("CREATE TABLE schema.destination_table ("
            "age integer, "
            "first_name varchar(20), "
            "last_name varchar(20)"
            ");")

with open(r'C:/tmp/people.csv', 'r') as f:
    next(f)  # Skip the header row. Or remove this line if csv has no header.
    conn.cursor.copy_expert("""COPY schema.destination_table FROM STDIN WITH (FORMAT CSV)""", f)

You can do something like this:

function writeFile(i){
    var i = i || 0;
    var fileName = 'a_' + i + '.jpg';
    fs.exists(fileName, function (exists) {
        if(exists){
            writeFile(++i);
        } else {
            fs.writeFile(fileName);
        }
    });
}

Here is an alternative that is an incremental improvement on several other answers. Assuming settings.aLengthMenu is not multi-dimensional (it can be when DataTables has row lengths and labels) and the data will not change after page load (for simple DOM-loaded DataTables), this function can be inserted to eliminate paging. It hides several paging-related classes.

Perhaps more robust would be setting paging to false inside the function below, however I don't see an API call for that off-hand.

$('#myTable').on('init.dt', function(evt, settings) {
    if (settings && settings.aLengthMenu && settings.fnRecordsTotal && settings.fnRecordsTotal() < settings.aLengthMenu[0]) {
        // hide pagination controls, fewer records than minimum length
        $(settings.nTableWrapper).find('.dataTables_paginate, .dataTables_length, .dataTables_info').hide();
    }
}).DataTable();

This works fine for 2 tables. I have 3 tables and on clause has to link 2 conditions from 3 tables. My code:

from p in _dbContext.Products join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId join jpr in leftJoinQuery on new { VariantId = pv.Vid, ProductId = p.ProduktId } equals new { VariantId = jpr.Prices.VariantID, ProductId = jpr.Prices.ProduktID } into lj

But its showing error at this point: join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId

Error: The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.

You can also try to make service based on window.sessionStorage or window.localStorage to keep state information between page reloads. I use it in the web app which is partially made in AngularJS and page URL is changed in "the old way" for some parts of workflow. Web storage is supported even by IE8. Here is angular-webstorage for convenience.

Another variant of the copy function using normal POSIX calls and without any loop. Code inspired from the buffer copy variant of the answer of caf. Warning: Using mmap can easily fail on 32 bit systems, on 64 bit system the danger is less likely.

#include <fcntl.h>
#include <unistd.h>
#include <errno.h>
#include <sys/mman.h>

int cp(const char *to, const char *from)
{
  int fd_from = open(from, O_RDONLY);
  if(fd_from < 0)
    return -1;
  struct stat Stat;
  if(fstat(fd_from, &Stat)<0)
    goto out_error;

  void *mem = mmap(NULL, Stat.st_size, PROT_READ, MAP_SHARED, fd_from, 0);
  if(mem == MAP_FAILED)
    goto out_error;

  int fd_to = creat(to, 0666);
  if(fd_to < 0)
    goto out_error;

  ssize_t nwritten = write(fd_to, mem, Stat.st_size);
  if(nwritten < Stat.st_size)
    goto out_error;

  if(close(fd_to) < 0) {
    fd_to = -1;
    goto out_error;
  }
  close(fd_from);

  /* Success! */
  return 0;
}
out_error:;
  int saved_errno = errno;

  close(fd_from);
  if(fd_to >= 0)
    close(fd_to);

  errno = saved_errno;
  return -1;
}

EDIT: Corrected the file creation bug. See comment in http://stackoverflow.com/questions/2180079/how-can-i-copy-a-file-on-unix-using-c/2180157#2180157 answer.

The bootstrap 3 docs for horizontal forms let you use the .form-horizontal class to make your form labels and inputs vertically aligned. The structure for these forms is:

<form class="form-horizontal" role="form">
  <div class="form-group">
    <label for="input1" class="col-lg-2 control-label">Label1</label>
    <div class="col-lg-10">
      <input type="text" class="form-control" id="input1" placeholder="Input1">
    </div>
  </div>
  <div class="form-group">
    <label for="input2" class="col-lg-2 control-label">Label2</label>
    <div class="col-lg-10">
      <input type="password" class="form-control" id="input2" placeholder="Input2">
    </div>
  </div>
</form>

Therefore, your form should look like this:

<form class="form-horizontal" role="form">
    <div class="form-group">
        <div class="col-xs-3">
            <label for="class_type"><h2><span class=" label label-primary">Class Type</span></h2></label>
        </div>
        <div class="col-xs-2">
            <select id="class_type" class="form-control input-lg" autocomplete="off">
                <option>Economy</option>
                <option>Premium Economy</option>
                <option>Club World</option>
                <option>First Class</option>
            </select>

function setRowColors() {
  var range = SpreadsheetApp.getActiveSheet().getDataRange();
  var statusColumnOffset = getStatusColumnOffset();

  for (var i = range.getRow(); i < range.getLastRow(); i++) {
    rowRange = range.offset(i, 0, 1);

function getStatusColumnOffset() {

  var range = SpreadsheetApp.getActiveSheet().getRange(1,1,1,lastColumn);

  for (var i = 0; i < range.getLastColumn(); i++) {
    if (range.offset(0, i, 1, 1).getValue() == "Status") {

    } 
  }
}

Do not concatenate. It's not needed, us commas as echo can take multiple parameters

echo "Welcome ", $name, "!";

Regarding using single or double quotes the difference is negligible, you can do tests with large numbers of strings to test for yourself.

flex: 1 means the following:

flex-grow : 1;    ? The div will grow in same proportion as the window-size       
flex-shrink : 1;  ? The div will shrink in same proportion as the window-size 
flex-basis : 0;   ? The div does not have a starting value as such and will 
                     take up screen as per the screen size available for
                     e.g:- if 3 divs are in the wrapper then each div will take 33%.

This might help? :)

Just search for the character at index 0 and compare it against the value you're looking for!

I added the following method to my PageBase class.

protected void Redirect(string url)
    {
        Response.Redirect(url);
    }
protected void Redirect(string url, NameValueCollection querystrings)
    {
        StringBuilder redirectUrl = new StringBuilder(url);

        if (querystrings != null)
        {
            for (int index = 0; index < querystrings.Count; index++)
            {
                if (index == 0)
                {
                    redirectUrl.Append("?");
                }

                redirectUrl.Append(querystrings.Keys[index]);
                redirectUrl.Append("=");
                redirectUrl.Append(HttpUtility.UrlEncode(querystrings[index]));

                if (index < querystrings.Count - 1)
                {
                    redirectUrl.Append("&");
                }
            }
        }

        this.Redirect(redirectUrl.ToString());
    }

To call:

NameValueCollection querystrings = new NameValueCollection();    
querystrings.Add("language", "en");
querystrings.Add("id", "134");
this.Redirect("http://www.mypage.com", querystrings);

Solution for me was to just do it server side

I used the C# WebClient library to get the data (in my case it was image data) and send it back to the client. There's probably something very similar in your chosen server-side language.

//Server side, api controller

[Route("api/ItemImage/GetItemImageFromURL")]
public IActionResult GetItemImageFromURL([FromQuery] string url)
{
    ItemImage image = new ItemImage();

    using(WebClient client = new WebClient()){

        image.Bytes = client.DownloadData(url);

        return Ok(image);
    }
}

You can tweak it to whatever your own use case is. The main point is client.DownloadData() worked without any CORS errors. Typically CORS issues are only between websites, hence it being okay to make 'cross-site' requests from your server.

Then the React fetch call is as simple as:

//React component

fetch(`api/ItemImage/GetItemImageFromURL?url=${imageURL}`, {            
        method: 'GET',
    })
    .then(resp => resp.json() as Promise<ItemImage>)
    .then(imgResponse => {

       // Do more stuff....
    )}

I used hfossli's answer and translated it to Swift

let IS_IPAD = UIDevice.currentDevice().userInterfaceIdiom == .Pad
let IS_IPHONE = UIDevice.currentDevice().userInterfaceIdiom == .Phone
let IS_RETINA = UIScreen.mainScreen().scale >= 2.0

let SCREEN_WIDTH = UIScreen.mainScreen().bounds.size.width
let SCREEN_HEIGHT = UIScreen.mainScreen().bounds.size.height
let SCREEN_MAX_LENGTH = max(SCREEN_WIDTH, SCREEN_HEIGHT)
let SCREEN_MIN_LENGTH = min(SCREEN_WIDTH, SCREEN_HEIGHT)

let IS_IPHONE_4_OR_LESS = (IS_IPHONE && SCREEN_MAX_LENGTH < 568.0)
let IS_IPHONE_5 = (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)
let IS_IPHONE_6 = (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)
let IS_IPHONE_6P = (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)

IMG elements are inline, meaning that unless they are floated they will flow horizontally with text and other inline elements.

They are "block" elements in that they have a width and a height. But they behave more like "inline-block" in that respect.

Select (Select count(y.au_lname) from dbo.authors y

order by Counterid --Alternatively that can be done which is equivalent as above..

My way

When you have a lot of insertion or deletion in the middle of the sequence. e.g. a memory manager.

Something that has worked for me in the past was to determine the offset (in milliseconds) between the user's timezone and GMT. Once you have the offset, you can simply add/subtract (depending on which way the conversion is going) to get the appropriate time in either timezone. I would usually accomplish this by setting the milliseconds field of a Calendar object, but I'm sure you could easily apply it to a timestamp object. Here's the code I use to get the offset

int offset = TimeZone.getTimeZone(timezoneId).getRawOffset();

timezoneId is the id of the user's timezone (such as EST).

ALTER TABLE t_name modify c_name INT(10) AUTO_INCREMENT PRIMARY KEY;

If the same error occurs in ADT/Eclipse

Add Action Bar Sherlock library in your project.

Now, to remove the "import The import android.support.v7 cannot be resolved" error download a jar file named as android-support-v7-appcompat.jar and add it in your project lib folder.

This will surely removes your both errors.

Two ways

window.frames['myIFrame'].contentDocument.getElementById('myIFrameElemId')

OR

window.frames['myIFrame'].contentWindow.document.getElementById('myIFrameElemId')

Update: I should have probably started with this as your projects are SNAPSHOTs. It is part of the SNAPSHOT semantics that Maven will check for updates on each build. Being a SNAPSHOT means that it is volatile and subject to change so updates should be checked for. However it's worth pointing out that the Maven super POM configures central to have snapshots disabled, so Maven shouldn't ever check for updates for SNAPSHOTs on central unless you've overridden that in your own pom/settings.

You can configure Maven to use a mirror for the central repository, this will redirect all requests that would normally go to central to your internal repository.

In your settings.xml you would add something like this to set your internal repository as as mirror for central:

<mirrors>
  <mirror>
    <id>ibiblio.org</id>
    <name>ibiblio Mirror of http://repo1.maven.org/maven2/</name>
    <url>http://path/to/my/repository</url>
    <mirrorOf>central</mirrorOf>
  </mirror>
</mirrors>

If you are using a repository manager like Nexus for your internal repository. You can set up a proxy repository for proxy central, so any requests that would normally go to Central are instead sent to your proxy repository (or a repository group containing the proxy), and subsequent requests are cached in the internal repository manager. You can even set the proxy cache timeout to -1, so it will never request for contents from central that are already on the proxy repository.

A more basic solution if you are only working with local repositories is to set the updatePolicy for the central repository to "never", this means Maven will only ever check for artifacts that aren't already in the local repository. This can then be overridden at the command line when needed by using the -U switch to force Maven to check for updates.

You would configure the repository (in your pom or a profile in the settings.xml) as follows:

<repository>
  <id>central</id>
  <url>http://repo1.maven.org/maven2</url>
  <updatePolicy>never</updatePolicy>
</repository>

You have it backwards. Display the calendar first, and then call gotoDate.

$('#calendar').fullCalendar({
  // Options
});

$('#calendar').fullCalendar('gotoDate', currentDate);

How about this method:

Set a field in the first object to a new value. If the same field in the second object has the same value, it's probably the same instance. Otherwise, exit as different.

Now set the field in the first object to a different new value. If the same field in the second object has changed to the different value, it's definitely the same instance.

Don't forget to set field in the first object back to it's original value on exit.

Problems?

You can see the log info in the console view of your IDE if you are not using any log4j properties to generate log file. You can define log4j.properties in your project so that those properties would be used to generate log file. A quick sample is listed below.

# Global logging configuration
log4j.rootLogger=DEBUG, stdout, R

# SQL Map logging configuration...
log4j.logger.com.ibatis=INFO
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=INFO

You can use the ZipArchive class to create a ZIP file and stream it to the client. Something like:

$files = array('readme.txt', 'test.html', 'image.gif');
$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
  $zip->addFile($file);
}
$zip->close();

and to stream it:

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);

The second line forces the browser to present a download box to the user and prompts the name filename.zip. The third line is optional but certain (mainly older) browsers have issues in certain cases without the content size being specified.

While some of the other approaches work, this is pretty close to what you were doing and only uses base r. If you know the aggregate command this may be more intuitive.

with( df , aggregate( dt , by=list(group) , FUN=summary)  )

I think, that will be good solution: /\S\w*/

Don't use wait(), use either android.os.SystemClock.sleep(1000); or Thread.sleep(1000);.

The main difference between them is that Thread.sleep() can be interrupted early -- you'll be told, but it's still not the full second. The android.os call will not wake early.

1) I have experienced same issue, my Xcode version was 7.0.1, and I updated my iPhone to version 9.2, then upon using Xcode, my iPhone was shown in the section of unavailable device. Just like in image below:

2) But then I somehow managed to select my iPhone by clicking at
Product -> Destination -> Unavailable Device

3) But that didn't solved my problem, and it started showing:

Could not find Developer Disk Image

Solution) Then finally I downloaded latest version of Xcode version 7.2 from here and everything has worked fine for me.

Update: Whenever version of iPhone device is higher than version of Xcode, you may experience same issue, so you should update your Xcode version to remove this error.

the Request.ServerVariables object works for me. I don't know of any reason not to use it.

ServerVariables["SERVER_NAME"] and ServerVariables["HTTP_URL"] should get what you're looking for

The documentation has the complete answer. Anyway this is how it is done:

<input type="text" ng-model="filterValue">
<li ng-repeat="i in data | filter:{age:filterValue}:true"> {{i | json }}</li>

will filter only age in data array and true is for exact match.

For deep filtering,

<li ng-repeat="i in data | filter:{$:filterValue}:true"> {{i}}</li>

The $ is a special property for deep filter and the true is for exact match like above.

You can extract a jar file with the command :

jar xf filename.jar

Assume your original xml is:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true"
        android:drawable="@drawable/tick_img" />
    <item android:state_checked="false"
        android:drawable="@drawable/untick_img" />
</selector>

then simply remove android:button="@drawable/xml_above" in your checkbox xml, and do drawable scaling programmatically in java (decrease the 150 big size to your desired dp):

CheckBox tickRememberPasswd = findViewById(R.id.remember_tick);

//custom selector size
Drawable drawableTick = ContextCompat.getDrawable(this, R.drawable.tick_img);
Drawable drawableUntick = ContextCompat.getDrawable(this, R.drawable.untick_img);
Bitmap bitmapTick = null;
if (drawableTick != null && drawableUntick != null) {
    int desiredPixels = Math.round(convertDpToPixel(150, this));

    bitmapTick = ((BitmapDrawable) drawableTick).getBitmap();
    Drawable dTick = new BitmapDrawable(getResources()
            , Bitmap.createScaledBitmap(bitmapTick, desiredPixels, desiredPixels, true));

    Bitmap bitmapUntick = ((BitmapDrawable) drawableUntick).getBitmap();
    Drawable dUntick = new BitmapDrawable(getResources()
            , Bitmap.createScaledBitmap(bitmapUntick, desiredPixels, desiredPixels, true));

    final StateListDrawable statesTick = new StateListDrawable();
    statesTick.addState(new int[] {android.R.attr.state_checked},
            dTick);
    statesTick.addState(new int[] { }, //else state_checked false
            dUntick);
    tickRememberPasswd.setButtonDrawable(statesTick);
}

the convertDpToPixel method:

public static float convertDpToPixel(float dp, Context context) {
    Resources resources = context.getResources();
    DisplayMetrics metrics = resources.getDisplayMetrics();
    float px = dp * (metrics.densityDpi / 160f);
    return px;
}

npm ws was the answer for me. I found it less intrusive and more straight forward. With it was also trivial to mix websockets with rest services. Shared simple code on this post.

var WebSocketServer = require("ws").Server;
var http = require("http");
var express = require("express");
var port = process.env.PORT || 5000;

var app = express();
    app.use(express.static(__dirname+ "/../"));
    app.get('/someGetRequest', function(req, res, next) {
       console.log('receiving get request');
    });
    app.post('/somePostRequest', function(req, res, next) {
       console.log('receiving post request');
    });
    app.listen(80); //port 80 need to run as root

    console.log("app listening on %d ", 80);

var server = http.createServer(app);
    server.listen(port);

console.log("http server listening on %d", port);

var userId;
var wss = new WebSocketServer({server: server});
    wss.on("connection", function (ws) {

    console.info("websocket connection open");

    var timestamp = new Date().getTime();
    userId = timestamp;

    ws.send(JSON.stringify({msgType:"onOpenConnection", msg:{connectionId:timestamp}}));


    ws.on("message", function (data, flags) {
        console.log("websocket received a message");
        var clientMsg = data;

        ws.send(JSON.stringify({msg:{connectionId:userId}}));


    });

    ws.on("close", function () {
        console.log("websocket connection close");
    });
});
console.log("websocket server created");

In Bootstrap 3 it is sufficient to call elt.attr('data-original-title', "Foo") as changes in the "data-original-title" attribute already trigger changes in the tooltip display.

UPDATE: You can add .tooltip('show') to show the changes immediately, you need not to mouseout and mouseover target to see the change in the title

elt.attr('data-original-title', "Foo").tooltip('show');

If you are plotting the same variables in both plots, the simplest way would be to combine the data frames into one, then use facet_wrap.

For your example:

big_df <- rbind(df1,df2)

big_df <- data.frame(big_df,Df = rep(c("df1","df2"),
times=c(nrow(df1),nrow(df2))))

ggplot(big_df,aes(x=x, y=y,colour=group)) 
+ geom_point(position=position_jitter(w=0.04,h=0.02),size=1.8) 
+ facet_wrap(~Df)

Another example using the diamonds data set. This shows that you can even make it work if you have only one variable common between your plots.

diamonds_reshaped <- data.frame(price = diamonds$price,
independent.variable = c(diamonds$carat,diamonds$cut,diamonds$color,diamonds$depth),
Clarity = rep(diamonds$clarity,times=4),
Variable.name = rep(c("Carat","Cut","Color","Depth"),each=nrow(diamonds)))

ggplot(diamonds_reshaped,aes(independent.variable,price,colour=Clarity)) + 
geom_point(size=2) + facet_wrap(~Variable.name,scales="free_x") + 
xlab("")

Only tricky thing with the second example is that the factor variables get coerced to numeric when you combine everything into one data frame. So ideally, you will do this mainly when all your variables of interest are the same type.

data, _ := ioutil.ReadAll(response.Body)
fmt.Println(string(data))

Here a solution using only std. However, note that this only rounds down.

    float number = 3.14159;
    std::string num_text = std::to_string(number);
    std::string rounded = num_text.substr(0, num_text.find(".")+3);

For rounded it yields:

3.14

The code converts the whole float to string, but cuts all characters 2 chars after the "."

$('#GridName').data('kendoGrid').dataSource.read();
$('#GridName').data('kendoGrid').refresh();

Calculate the intersection point of the lines laying on your segments (it means basically to solve a linear equation system), then check whether is it between the starting and ending points of your segments.

Looks like you use %p: Print Pointers

About int() and Swift 2.x: if you get a nil value after conversion check if you try to convert a string with a big number (for example: 1073741824), in this case try:

let bytesInternet : Int64 = Int64(bytesInternetString)!

you can also use vertice :

private static final int verticesColors[] = {
    Color.LTGRAY, Color.LTGRAY, Color.LTGRAY, 0xFF000000, 0xFF000000, 0xFF000000
};
float verts[] = {
    point1.x, point1.y, point2.x, point2.y, point3.x, point3.y
};
canvas.drawVertices(Canvas.VertexMode.TRIANGLES, verts.length, verts, 0, null, 0, verticesColors,   0, null, 0, 0, new Paint());

Beautiful! Your solution was 99%... instead of "this.scrollY", I used "$(window).scrollTop()". What's even better is that this solution only requires the jQuery1.2.6 library (no additional libraries needed).

The reason I wanted that version in particular is because that's what ships with MVC currently.

Here's the code:

$(document).ready(function() {
    $("#topBar").css("position", "absolute");
});

$(window).scroll(function() {
    $("#topBar").css("top", $(window).scrollTop() + "px");
});

Although it's too late , But here is my experience .

Whenever you get your maven project from a source controller or just copying your project from one machine to another , you need to update the dependencies .

For this Right-click on Project on project explorer -> Maven -> Update Project.

Please consider checking the "Force update of snapshot/releases" checkbox.

If you have not your dependencies in m2/repository then you need internet connection to get from the remote maven repository.

In case you have get from the source controller and you have not any unit test , It's probably your test folder does not include in the source controller in the first place , so you don't have those in the new repository.so you need to create those folders manually.

I have had both these cases .

This is just an explanation not addressed in other answers

At least in recent versions of Mysql, your first query is not committed.

If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.

What's going on?

When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.

So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE, UPDATE, INSERT or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).

That's why the solution involves declaring handlers to immediately ROLLBACK when an error happens.

Extra

Inside the handler you can also re-raise the error using RESIGNAL, otherwise the stored procedure executes "Successfully"

BEGIN
    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
        BEGIN
            ROLLBACK;
            RESIGNAL;
        END;

    START TRANSACTION;
        #.. Query 1 ..
        #.. Query 2 ..
        #.. Query 3 ..
    COMMIT;
END

My answer is an amalgamation of the above two with extension to drawing sphere of user-defined opacity and some annotation. It finds application in b-vector visualization on a sphere for magnetic resonance image (MRI). Hope you find it useful:

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.gca(projection='3d')

# draw sphere
u, v = np.mgrid[0:2*np.pi:50j, 0:np.pi:50j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
# alpha controls opacity
ax.plot_surface(x, y, z, color="g", alpha=0.3)


# a random array of 3D coordinates in [-1,1]
bvecs= np.random.randn(20,3)

# tails of the arrows
tails= np.zeros(len(bvecs))

# heads of the arrows with adjusted arrow head length
ax.quiver(tails,tails,tails,bvecs[:,0], bvecs[:,1], bvecs[:,2],
          length=1.0, normalize=True, color='r', arrow_length_ratio=0.15)

ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')

ax.set_title('b-vectors on unit sphere')

plt.show()

If you want to copy from searchContent to content, then code should be as follows

BeanUtils.copyProperties(content, searchContent);

You need to reverse the parameters as above in your code.

From API,

public static void copyProperties(Object dest, Object orig)
                           throws IllegalAccessException,
                                  InvocationTargetException)

Parameters:

dest - Destination bean whose properties are modified

orig - Origin bean whose properties are retrieved

To initialize 2d array with zero use the below method: int arr[n][m] = {};

I had a user control which sat on page in a free form way, not constrained by another container, and the contents within the user control would not auto size but expand to the full size of what the user control was handed.

To get the user control to simply size to its content, for height only, I placed it into a grid with on row set to auto size such as this:

<Grid Margin="0,60,10,200">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />

Check the mvn script in your maven installation to see how it's building the command. Perhaps you or someone else has hard-coded a JAVA_HOME in there and forgotten about it.

My site faces same issue too.

Using Facebook debug tool is no help at all. Fetch new data but not IMAGE CACHE.

I forced facebook to clear IMAGE CACHE by add www. into image url. In your case is remove www. and config web server redirect.

 add/remove www. in image url should solve the problem

An important difference is that some UARTs (16550 notably) will stop receiving characters immediately if their host instructs them to set DSR to be inactive. In contrast, characters will still be received if CTS is inactive. I believe that the intention here is that DSR indicates that the device is no longer listening and so sending any further characters is pointless, while CTS indicates that a buffer is getting full; the latter allows for a certain amount of 'skid' where the flow control line changed state between the DTE sampling it and the next character being transmitted. In (relatively) later devices that support a hardware FIFO it's possible that a number of characters could be transmitted after the DCE has set CTS to be inactive.

I seem to be a bit late to the party and much more of a beginner than any expertise; BUT this worked for me:

window.onbeforeunload = function() {
      return false;
};

I placed this as an inline script immediately after my Head and Meta elements, like this:

<script>
  window.onbeforeunload = function() {
     return false;
  }
</script>

This page seems to me to be highly relevant to the originator's requirement (especially the sections headed window.onunload and window.onbeforeunload): https://javascript.info/onload-ondomcontentloaded

Hoping this helps.

here's blinking with animation:

$(".blink").animate({opacity:0},200,"linear",function(){
  $(this).animate({opacity:1},200);
});

just give a blink class whatever u want to blink:

<div class="someclass blink">some text</div>

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

According to List of XML and HTML character entity references:

∞

The Google search using your original question gets several useful results: How can I display an infinity symbol using HTML.

In case I just want to know how many unique factor levels exist in the data, I use:

length(unique(df$factorcolumn))

UK Government Data Standards Catalogue details the UK standards for this kind of thing. It suggests 35 characters for each of Given Name and Family Name, or 70 characters for a single field to hold the Full Name, and 255 characters for an email address. Amongst other things..

You can use the following solution to accomplish your goal:

struct student 
{
    char name[20];
    char country[20];
};
void main()
{
    struct student S={"Wolverine","America"};
    struct student X;
    X=S;
    printf("%s%s",X.name,X.country);
}

Three problems here:

1. Just use String.matches() - if the API is there, use it
2. In java "matches" means "matches the entire input", which IMHO is counter-intuitive, so let your method's API reflect that by letting callers think about matching part of the input as your example suggests
3. You regex matches only 1 character

I recommend you use code like this:

public boolean matches(String regex) {
    regex = "^.*" + regex + ".*$"; // pad with regex to allow partial matching
    System.out.println("abcABC   ".matches(regex));
    return "abcABC   ".matches(regex);
}

public static void main(String[] args) {
    HowEasy words = new HowEasy();
    words.matches("[a-zA-Z]+"); // added "+" (ie 1-to-n of) to character class
}

If stuffs is a list of strings, just this would work:

{{ stuffs|join(", ") }}

Link to join filter documentation, link to filters in general documentation.

p.s.

More reader friendly way {{ my ~ ', ' ~ string }}

From Python version 2.6 on you can use multiple arguments to set.intersection(), like

u = set.intersection(s1, s2, s3)

If the sets are in a list, this translates to:

u = set.intersection(*setlist)

where *a_list is list expansion

Note that set.intersection is not a static method, but this uses the functional notation to apply intersection of the first set with the rest of the list. So if the argument list is empty this will fail.

For enabling readonly:

$("#descrip").attr("readonly","true");

For disabling readonly

$("#descrip").attr("readonly","");

Try using

for i in a :
  print(i[0])

i represents individual row in a.So,i[0] represnts the 1st element of each row.

If you use the flask executable to start your server, you can use flask run --host=0.0.0.0 to change the default from 127.0.0.1 and open it up to non local connections. The config and app.run methods that the other answers describe are probably better practice but this can be handy as well.

Externally Visible Server If you run the server you will notice that the server is only accessible from your own computer, not from any other in the network. This is the default because in debugging mode a user of the application can execute arbitrary Python code on your computer.

If you have the debugger disabled or trust the users on your network, you can make the server publicly available simply by adding --host=0.0.0.0 to the command line:

flask run --host=0.0.0.0 This tells your operating system to listen on all public IPs.

I would create a variable to store the input like this:

var input = document.getElementById("input_id").value;

And then I would just use the variable to add the input value to the string.

= "Your string" + input;

The cheapest and dirtiest way to do it is simply make microtime() calls at places in your code you want to benchmark. Do it right before and right after database queries and it's simple to remove those durations from the rest of your script execution time.

A hint: your PHP execution time is rarely going to be the thing that makes your script timeout. If a script times out it's almost always going to be a call to an external resource.

(Good intro article part 1, part 2, part 3. As for compelling reasons, that depends on what you are using SQL server for. Do you need hierarchical data types? Do you currently store files in the database and want to switch over to SQL Server's new filestream feature? Could you use more disk space by turning on data compression?

And let's not forget the ability to MERGE data.

You can use the sibling selector ~:

h1.hc-reform ~ p{
     clear:both;
}

This selects all the p elements that come after .hc-reform, not just the first one.

If you look in the source code of the JDK, you can see that for unix systems the property is read at compile time from the paths.h or hard coded. For windows the function GetTempPathW from win32 returns the tmpdir name.

For posix systems you might expect the standard TMPDIR to work, but that is not the case. You can confirm that TMPDIR is not used by running TMPDIR=/mytmp java -XshowSettings

I had a similar issue, but it was related to Hibernate's bi-directional relationships. I wanted to show one side of the relationship and programmatically ignore the other, depending on what view I was dealing with. If you can't do that, you end up with nasty StackOverflowExceptions. For instance, if I had these objects

public class A{
  Long id;
  String name;
  List<B> children;
}

public class B{
  Long id;
  A parent;
}

I would want to programmatically ignore the parent field in B if I were looking at A, and ignore the children field in A if I were looking at B.

I started off using mixins to do this, but that very quickly becomes horrible; you have so many useless classes laying around that exist solely to format data. I ended up writing my own serializer to handle this in a cleaner way: https://github.com/monitorjbl/json-view.

It allows you programmatically specify what fields to ignore:

ObjectMapper mapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addSerializer(JsonView.class, new JsonViewSerializer());
mapper.registerModule(module);

List<A> list = getListOfA();
String json = mapper.writeValueAsString(JsonView.with(list)
    .onClass(B.class, match()
        .exclude("parent")));

It also lets you easily specify very simplified views through wildcard matchers:

String json = mapper.writeValueAsString(JsonView.with(list)
    .onClass(A.class, match()
        .exclude("*")
         .include("id", "name")));

In my original case, the need for simple views like this was to show the bare minimum about the parent/child, but it also became useful for our role-based security. Less privileged views of objects needed to return less information about the object.

All of this comes from the serializer, but I was using Spring MVC in my app. To get it to properly handle these cases, I wrote an integration that you can drop in to existing Spring controller classes:

@Controller
public class JsonController {
  private JsonResult json = JsonResult.instance();
  @Autowired
  private TestObjectService service;

  @RequestMapping(method = RequestMethod.GET, value = "/bean")
  @ResponseBody
  public List<TestObject> getTestObject() {
    List<TestObject> list = service.list();

    return json.use(JsonView.with(list)
        .onClass(TestObject.class, Match.match()
            .exclude("int1")
            .include("ignoredDirect")))
        .returnValue();
  }
}

Both are available on Maven Central. I hope it helps someone else out there, this is a particularly ugly problem with Jackson that didn't have a good solution for my case.

Simply you can use web.xml to add error code and 404 error page. But make sure 404 error page must not locate under WEB-INF.

<error-page>
    <error-code>404</error-code>
    <location>/404.html</location>
</error-page>

This is the simplest way to do it but this have some limitation. Suppose if you want to add the same style for this page that you added other pages. In this way you can't to that. You have to use the @ResponseStatus(value = HttpStatus.NOT_FOUND)

This is a syntax issue, the jQuery library included with WordPress loads in "no conflict" mode. This is to prevent compatibility problems with other javascript libraries that WordPress can load. In "no-confict" mode, the $ shortcut is not available and the longer jQuery is used, i.e.

jQuery(document).ready(function ($) {

By including the $ in parenthesis after the function call you can then use this shortcut within the code block.

For full details see WordPress Codex

__VA_ARGS__ is the standard way to do it. Don't use compiler-specific hacks if you don't have to.

I'm really annoyed that I can't comment on the original post. In any case, C++ is not a superset of C. It is really silly to compile your C code with a C++ compiler. Don't do what Donny Don't does.

In a simple manner you can also try to just run a pre-packaged docker with intellij, I found the good job of @dlsniper : https://hub.docker.com/r/dlsniper/docker-intellij/

you just need to have docker installed and to run :

docker run -tdi \
       --net="host" \
       --privileged=true \
       -e DISPLAY=${DISPLAY} \
       -v /tmp/.X11-unix:/tmp/.X11-unix \
       -v ${HOME}/.IdeaIC2016.1_docker:/home/developer/.IdeaIC2016.1 \
       -v ${GOPATH}:/home/developer/go \
       dlsniper/docker-intellij

I solved this by putting the following in my login.php page.

<script type="text/javascript">
    if (top.location.href.indexOf('login.php') == -1) {
        top.location.href = '/login.php';
    }
</script>

A container's logs can be found in :

/var/lib/docker/containers/<container id>/<container id>-json.log

(if you use the default log format which is json)

Since this questions seems to still get quite a lot of views, it might be useful to note that for Spring 4+ it's easiest to start using Spring Boot and the Spring Boot starter POMs.

Using Spring Boot there's less dependencies to manage (and thus fewer conflicts), and setting up a working, well integrated Spring Context is a whole lot easier. I highly recommend it.

In html use

<input :required="condition" />

And define in data property like

data () {
   return {
      condition: false
   }
}

You can change configuration file schema back to DotNetConfig.xsd via properties of the app.config file. To find destination of needed schema, you can search it by name or create a WinForms application, add to project the configuration file and in it's properties, you'll find full path to file.

A single liner, using find:

find -type f -exec grep -lm1 "PATTERN" {} \; -a -quit

We had the same problem while working on an Android application for a customer and I managed to "hack" around this restriction.

I took a look at the Android Source code for the WebView class and spotted a updateZoomButtonsEnabled()-method which was working with an ZoomButtonsController-object to enable and disable the zoom controls depending on the current scale of the browser.

I searched for a method to return the ZoomButtonsController-instance and found the getZoomButtonsController()-method, that returned this very instance.

Although the method is declared public, it is not documented in the WebView-documentation and Eclipse couldn't find it either. So, I tried some reflection on that and created my own WebView-subclass to override the onTouchEvent()-method, which triggered the controls.

public class NoZoomControllWebView extends WebView {

    private ZoomButtonsController zoom_controll = null;

    public NoZoomControllWebView(Context context) {
        super(context);
        disableControls();
    }

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

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

    /**
     * Disable the controls
     */
    private void disableControls(){
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
            // Use the API 11+ calls to disable the controls
            this.getSettings().setBuiltInZoomControls(true);
            this.getSettings().setDisplayZoomControls(false);
        } else {
            // Use the reflection magic to make it work on earlier APIs
            getControlls();
        }
    }

    /**
     * This is where the magic happens :D
     */
    private void getControlls() {
        try {
            Class webview = Class.forName("android.webkit.WebView");
            Method method = webview.getMethod("getZoomButtonsController");
            zoom_controll = (ZoomButtonsController) method.invoke(this, null);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        super.onTouchEvent(ev);
        if (zoom_controll != null){
            // Hide the controlls AFTER they where made visible by the default implementation.
            zoom_controll.setVisible(false);
        }
        return true;
    }
}

You might want to remove the unnecessary constructors and react on probably on the exceptions.

Although this looks hacky and unreliable, it works back to API Level 4 (Android 1.6).

As @jayellos pointed out in the comments, the private getZoomButtonsController()-method is no longer existing on Android 4.0.4 and later.

However, it doesn't need to. Using conditional execution, we can check if we're on a device with API Level 11+ and use the exposed functionality (see @Yuttadhammo answer) to hide the controls.

I updated the example code above to do exactly that.

I did that with two steps. Make a list of csv files in one file With a help of this page comments I made two scriptless steps to get what I needed. Just type into terminal:

$ find /csv/file/dir -name '*.csv' > csv_list.txt
$ grep -q Svenska `cat csv_list.txt` && grep -q Norsk `cat csv_list.txt` && grep -l Dansk `cat csv_list.txt`

it did exactly what I needed - print file names containing all three words.

Also mind the symbols like `' "

For what it's worth, I've run into this on what was previously working code. I had added SELECT statements in a trigger for debug testing and forgot to remove them. Entity Framework / MVC doesnt play nice when other stuff is output to the "grid". Make sure to check for any rogue queries and remove them.
