Programs & Examples On #Formsets

I very recently had the some problem and just figured out how to do this. Assuming you have three classes, Primary, B, C and that B,C have a foreign key to primary

    class PrimaryForm(ModelForm):
        class Meta:
            model = Primary

    class BForm(ModelForm):
        class Meta:
            model = B
            exclude = ('primary',)

    class CForm(ModelForm):
         class Meta:
            model = C
            exclude = ('primary',)

    def generateView(request):
        if request.method == 'POST': # If the form has been submitted...
            primary_form = PrimaryForm(request.POST, prefix = "primary")
            b_form = BForm(request.POST, prefix = "b")
            c_form = CForm(request.POST, prefix = "c")
            if primary_form.is_valid() and b_form.is_valid() and c_form.is_valid(): # All validation rules pass
                    print "all validation passed"
                    primary = primary_form.save()
                    b_form.cleaned_data["primary"] = primary
                    b = b_form.save()
                    c_form.cleaned_data["primary"] = primary
                    c = c_form.save()
                    return HttpResponseRedirect("/viewer/%s/" % (primary.name))
            else:
                    print "failed"

        else:
            primary_form = PrimaryForm(prefix = "primary")
            b_form = BForm(prefix = "b")
            c_form = Form(prefix = "c")
     return render_to_response('multi_model.html', {
     'primary_form': primary_form,
     'b_form': b_form,
     'c_form': c_form,
      })

This method should allow you to do whatever validation you require, as well as generating all three objects on the same page. I have also used javascript and hidden fields to allow the generation of multiple B,C objects on the same page.

Go to "Run" and execute this:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

NOTE: run as administrator.

Vertical align only works in some select cases. The easiest way to make it function is to set display: table in the parent element's CSS and display: table-cell; to the child element and then apply your vertical align attribute.

select 1 from table

will return a column of 1's for every row in the table. You could use it with a where statement to check whether you have an entry for a given key, as in:

if exists(select 1 from table where some_column = 'some_value')

What your friend was probably saying is instead of making bulk selects with select * from table, you should specify the columns that you need precisely, for two reasons:

1) performance & you might retrieve more data than you actually need.

2) the query's user may rely on the order of columns. If your table gets updated, the client will receive columns in a different order than expected.

Functions are another type of variable in JavaScript (with some nuances of course). Creating a function within another function changes the scope of the function in the same way it would change the scope of a variable. This is especially important for use with closures to reduce total global namespace pollution.

The functions defined within another function won't be accessible outside the function unless they have been attached to an object that is accessible outside the function:

function foo(doBar)
{
  function bar()
  {
    console.log( 'bar' );
  }

  function baz()
  {
    console.log( 'baz' );
  }

  window.baz = baz;
  if ( doBar ) bar();
}

In this example, the baz function will be available for use after the foo function has been run, as it's overridden window.baz. The bar function will not be available to any context other than scopes contained within the foo function.

as a different example:

function Fizz(qux)
{
  this.buzz = function(){
    console.log( qux );
  };
}

The Fizz function is designed as a constructor so that, when run, it assigns a buzz function to the newly created object.

Easiest way I find is to:

1. Right click project

2. Debug as -> Maven build ...

3. In the goals field put -Dmaven.surefire.debug test

4. In the parameters put a new parameter called forkCount with a value of 0 (previously was forkMode=never but it is deprecated and doesn't work anymore)

Set your breakpoints down and run this configuration and it should hit the breakpoint.

decodeURIComponent() is fine, but you never want ot use encodeURIComponent() directly. This fails to escape reserved characters like *, !, ', (, and ). Check out RFC3986, where this is defined, for more info on that. The Mozilla Developer Network documentation gives both a good explanation and a solution. Explanation...

To be more stringent in adhering to RFC 3986 (which reserves !, ', (, ), and *), even though these characters have no formalized URI delimiting uses, the following can be safely used:

Solution...

function fixedEncodeURIComponent(str) {
  return encodeURIComponent(str).replace(/[!'()*]/g, function(c) {
    return '%' + c.charCodeAt(0).toString(16);
  });
}

In case you're not sure, check out a good, working demo at JSBin.com. Compare this with a bad, working demo at JSBin.com using encodeURIComponent() directly.

Good code results:

thing%2athing%20thing%21

Bad code results from encodeURIComponent():

thing*thing%20thing!

I was having the same problem while developing my own website. While it was resident locally, resources opened as file//. For pages from the internet, including my own loaded as http://, the F12 Developer did use Edge as default, but not while they were loaded into IE11 from local files.

After following the suggestions above, I unchecked the box for "Display intranet Sites in Compatibility View".

That did the trick without adding any extra coding to my web page, or adding a multitude of pages to populate the list. Now all local files open in Edge document mode with F12.

So if you are referring to using F12 for locally hosted files, this may help.

There are many way to get application context in Spring application. Those are given bellow:

1. Via ApplicationContextAware:

   import org.springframework.beans.BeansException;
   import org.springframework.context.ApplicationContext;
   import org.springframework.context.ApplicationContextAware;
   
   public class AppContextProvider implements ApplicationContextAware {
   
   private ApplicationContext applicationContext;
   
   @Override
   public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
       this.applicationContext = applicationContext;
   }
   }
   

Here setApplicationContext(ApplicationContext applicationContext) method you will get the applicationContext

ApplicationContextAware:

Interface to be implemented by any object that wishes to be notified of the ApplicationContext that it runs in. Implementing this interface makes sense for example when an object requires access to a set of collaborating beans.

2. Via Autowired:

   @Autowired
   private ApplicationContext applicationContext;
   

Here @Autowired keyword will provide the applicationContext. Autowired has some problem. It will create problem during unit-testing.

One alternative would be to use a getter/setter methods.

For instance, if you only care about reading the calculated value:

var book  = {}

Object.defineProperties(book,{
    key1: { value: "it", enumerable: true },
    key2: {
        enumerable: true,
        get: function(){
            return this.key1 + " works!";
        }
    }
});

console.log(book.key2); //prints "it works!"

The above code, though, won't let you define another value for key2.

So, the things become a bit more complicated if you would like to also redefine the value of key2. It will always be a calculated value. Most likely that's what you want.

However, if you would like to be able to redefine the value of key2, then you will need a place to cache its value independently of the calculation.

Somewhat like this:

var book  = { _key2: " works!" }

Object.defineProperties(book,{
    key1: { value: "it", enumerable: true},
    _key2: { enumerable: false},
    key2: {
        enumerable: true,
        get: function(){
            return this.key1 + this._key2;
        },
        set: function(newValue){
            this._key2 = newValue;
        }
    }
});

console.log(book.key2); //it works!

book.key2 = " doesn't work!";
console.log(book.key2); //it doesn't work!

for(var key in book){
    //prints both key1 and key2, but not _key2
    console.log(key + ":" + book[key]); 
}

Another interesting alternative is to use a self-initializing object:

var obj = ({
  x: "it",
  init: function(){
    this.y = this.x + " works!";
    return this;
  }
}).init();

console.log(obj.y); //it works!

I think the classic answer is to create a more decoupled application, which has no knowledge of which implementation will be used during runtime.

For example, we're a central payment provider, working with many payment providers around the world. However, when a request is made, I have no idea which payment processor I'm going to call. I could program one class with a ton of switch cases, such as:

class PaymentProcessor{

    private String type;

    public PaymentProcessor(String type){
        this.type = type;
    }

    public void authorize(){
        if (type.equals(Consts.PAYPAL)){
            // Do this;
        }
        else if(type.equals(Consts.OTHER_PROCESSOR)){
            // Do that;
        }
    }
}

Now imagine that now you'll need to maintain all this code in a single class because it's not decoupled properly, you can imagine that for every new processor you'll support, you'll need to create a new if // switch case for every method, this only gets more complicated, however, by using Dependency Injection (or Inversion of Control - as it's sometimes called, meaning that whoever controls the running of the program is known only at runtime, and not complication), you could achieve something very neat and maintainable.

class PaypalProcessor implements PaymentProcessor{

    public void authorize(){
        // Do PayPal authorization
    }
}

class OtherProcessor implements PaymentProcessor{

    public void authorize(){
        // Do other processor authorization
    }
}

class PaymentFactory{

    public static PaymentProcessor create(String type){

        switch(type){
            case Consts.PAYPAL;
                return new PaypalProcessor();

            case Consts.OTHER_PROCESSOR;
                return new OtherProcessor();
        }
    }
}

interface PaymentProcessor{
    void authorize();
}

** The code won't compile, I know :)

I've found String.fromCharCode(13, 10) helpful when using view engines. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/fromCharCode

This creates a string with the actual newline characters in it and so forces the view engine to output a newline rather than an escaped version. Eg: Using NodeJS EJS view engine - This is a simple example in which any \n should be replaced:

viewHelper.js

exports.replaceNewline = function(input) {
    var newline = String.fromCharCode(13, 10);
    return input.replaceAll('\\n', newline);
}

EJS

<textarea><%- viewHelper.replaceNewline("Blah\nblah\nblah") %></textarea>

Renders

<textarea>Blah
blah
blah</textarea>

replaceAll:

String.prototype.replaceAll = function (find, replace) {
    var result = this;
    do {
        var split = result.split(find);
        result = split.join(replace);
    } while (split.length > 1);
    return result;
};

Kotlin version of using LocalBroadcastManager:

Please check the below code for registering, sending and receiving the broadcast message.

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // register broadcast manager
        val localBroadcastManager = LocalBroadcastManager.getInstance(this)
        localBroadcastManager.registerReceiver(receiver, IntentFilter("your_action"))
    }

    // broadcast receiver
    var receiver: BroadcastReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent?) {
            if (intent != null) {
                val str = intent.getStringExtra("key")
                
            }
        }
    }

    /**
     * Send broadcast method
     */
    fun sendBroadcast() {
        val intent = Intent("your_action")
        intent.putExtra("key", "Your data")
        LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
    }

    override fun onDestroy() {
        // Unregister broadcast
        LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver)
        super.onDestroy()
    }

}

The best and the most effective way to learn new things is to see and study real world practical examples. Suppose for a moment that you want to build a blog in django where reporters can write and publish news articles. The owner of the online newspaper wants to allow each of his reporters to publish as many articles as they want, but does not want different reporters to work on the same article. This means that when readers go and read an article they will se only one author in the article.

For example: Article by John, Article by Harry, Article by Rick. You can not have Article by Harry & Rick because the boss does not want two or more authors to work on the same article.

How can we solve this 'problem' with the help of django? The key to the solution of this problem is the django ForeignKey.

The following is the full code which can be used to implement the idea of our boss.

from django.db import models

# Create your models here.

class Reporter(models.Model):
    first_name = models.CharField(max_length=30)

    def __unicode__(self):
        return self.first_name


class Article(models.Model):
    title = models.CharField(max_length=100)
    reporter = models.ForeignKey(Reporter)

    def __unicode__(self):
        return self.title

Run python manage.py syncdb to execute the sql code and build the tables for your app in your database. Then use python manage.py shell to open a python shell.

Create the Reporter object R1.

In [49]: from thepub.models import Reporter, Article

In [50]: R1 = Reporter(first_name='Rick')

In [51]: R1.save()

Create the Article object A1.

In [5]: A1 = Article.objects.create(title='TDD In Django', reporter=R1)

In [6]: A1.save()

Then use the following piece of code to get the name of the reporter.

In [8]: A1.reporter.first_name
Out[8]: 'Rick'

Now create the Reporter object R2 by running the following python code.

In [9]: R2 = Reporter.objects.create(first_name='Harry')

In [10]: R2.save()

Now try to add R2 to the Article object A1.

In [13]: A1.reporter.add(R2)

It does not work and you will get an AttributeError saying 'Reporter' object has no attribute 'add'.

As you can see an Article object can not be related to more than one Reporter object.

What about R1? Can we attach more than one Article objects to it?

In [14]: A2 = Article.objects.create(title='Python News', reporter=R1)

In [15]: R1.article_set.all()
Out[15]: [<Article: Python News>, <Article: TDD In Django>]

This practical example shows us that django ForeignKey is used to define many-to-one relationships.

OneToOneField is used to create one-to-one relationships.

We can use reporter = models.OneToOneField(Reporter) in the above models.py file but it is not going to be useful in our example as an author will not be able to post more than one article.

Each time you want to post a new article you will have to create a new Reporter object. This is time consuming, isn't it?

I highly recommend to try the example with the OneToOneField and realize the difference. I am pretty sure that after this example you will completly know the difference between django OneToOneField and django ForeignKey.

Escaping quotes in VB6 or VBScript strings is simple in theory although often frightening when viewed. You escape a double quote with another double quote.

An example:

"c:\program files\my app\app.exe"

If I want to escape the double quotes so I could pass this to the shell execute function listed by Joe or the VB6 Shell function I would write it:

escapedString = """c:\program files\my app\app.exe"""

How does this work? The first and last quotes wrap the string and let VB know this is a string. Then each quote that is displayed literally in the string has another double quote added in front of it to escape it.

It gets crazier when you are trying to pass a string with multiple quoted sections. Remember, every quote you want to pass has to be escaped.

If I want to pass these two quoted phrases as a single string separated by a space (which is not uncommon):

"c:\program files\my app\app.exe" "c:\documents and settings\steve"

I would enter this:

escapedQuoteHell = """c:\program files\my app\app.exe"" ""c:\documents and settings\steve"""

I've helped my sysadmins with some VBScripts that have had even more quotes.

It's not pretty, but that's how it works.

The only difference between innerText and innerHTML is that innerText insert string as it is into the element, while innerHTML run it as html content.

const ourstring = 'My name is <b class="name">Satish chandra Gupta</b>.';_x000D_
document.getElementById('innertext').innerText = ourstring;_x000D_
document.getElementById('innerhtml').innerHTML = ourstring;

.name{_x000D_
color:red;_x000D_
}

<h3>Inner text below. It inject string as it is into the element.</h3>_x000D_
<div id="innertext"></div>_x000D_
<br />_x000D_
<h3>Inner html below. It renders the string into the element and treat as part of html document.</h3>_x000D_
<div id="innerhtml"></div>

I went to the docker settings and changed the image space available. It reached the limit while creating the new image with docker build. So I just increased the amount available.

Regex object is thread-safe for Matching functions. Knowing that and there are some performance options or cultural / language issues, I propose this simple solution.

public static Regex _regex = new Regex(
    @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
    RegexOptions.CultureInvariant | RegexOptions.Singleline);

public static bool IsValidEmailFormat(string emailInput)
{
    return _regex.IsMatch(emailInput);
}

Alternative Configuration for Regex:

public static Regex _regex = new Regex(
    @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
    RegexOptions.CultureInvariant | RegexOptions.Compiled);

I find that compiled is only faster on big string matches, like book parsing for example. Simple email matching is faster just letting Regex interpret.

Add the following code to your view controller:

if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
    // iOS 7
    [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
} else {
    // iOS 6
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

For those who still might be facing issue adding jsx to test fixed it for me

test: /\.jsx?$/,

Yes. You can get an element by its ID by calling document.getElementById. It will return an element node if found, and null otherwise:

var x = document.getElementById("elementid");   // Get the element with id="elementid"
x.style.color = "green";                        // Change the color of the element

You need to change the default layout type of top level QWidget object from Break layout type to other layout types (Vertical Layout, Horizontal Layout, Grid Layout, Form Layout). For example:

To something like this:

For a list of available flags:

grep --help 

Returns all matches for the regexp texthere in the current directory, with the corresponding line number:

grep -rn "texthere" .

Returns all matches for texthere, starting at the root directory, with the corresponding line number and ignoring case:

grep -rni "texthere" /

flags used here:

• -r recursive
• -n print line number with output
• -i ignore case

Try this:

if [ $STATUS -ne 200 -a "$STRING" != "$VALUE" ]; then

Use String.PadLeft like this:

var result = input.ToString().PadLeft(length, '0');

According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:

• Informing each search engine of the location through their provided interface
• Adding url to the robots.txt file
• Submiting url to search engines through http

So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.

Other answers are correct to suggest Sort, but they seem to have missed the fact that the storage location is typed as IList<string. Sort is not part of the interface.

If you know that ListaServizi will always contain a List<string>, you can either change its declared type, or use a cast. If you're not sure, you can test the type:

if (typeof(List<string>).IsAssignableFrom(ListaServizi.GetType()))
    ((List<string>)ListaServizi).Sort();
else
{
    //... some other solution; there are a few to choose from.
}

Perhaps more idiomatic:

List<string> typeCheck = ListaServizi as List<string>;
if (typeCheck != null)
    typeCheck.Sort();
else
{
    //... some other solution; there are a few to choose from.
}

If you know that ListaServizi will sometimes hold a different implementation of IList<string>, leave a comment, and I'll add a suggestion or two for sorting it.

Checkboxes are posting value 'on' if and only if the checkbox is checked. Insted of catching checkbox value you can use hidden inputs

JS:

var chk = $('input[type="checkbox"]');
    chk.each(function(){
        var v = $(this).attr('checked') == 'checked'?1:0;
        $(this).after('<input type="hidden" name="'+$(this).attr('rel')+'" value="'+v+'" />');
    });

chk.change(function(){ 
        var v = $(this).is(':checked')?1:0;
        $(this).next('input[type="hidden"]').val(v);
    });

HTML:

<label>Active</label><input rel="active" type="checkbox" />

Queues are First In First Out structures. You request is pretty vague, but I am guessing that you need only the basic functionality which usually comes out with Queue structures. You can take a look at how you can implement it here.

With regards to your missing package, it is most likely because you will need to either download or create the package yourself by following that tutorial.

Add this to your project file:

CONFIG += console

Truncating .TotalSeconds is important since it's defined as the value of the current System.TimeSpan structure expressed in whole fractional seconds.

And how about an extension for DateTime? The second one is probably more confusing that it's worth until property extensions exist.

/// <summary>
/// Converts a given DateTime into a Unix timestamp
/// </summary>
/// <param name="value">Any DateTime</param>
/// <returns>The given DateTime in Unix timestamp format</returns>
public static int ToUnixTimestamp(this DateTime value)
{
    return (int)Math.Truncate((value.ToUniversalTime().Subtract(new DateTime(1970, 1, 1))).TotalSeconds);
}

/// <summary>
/// Gets a Unix timestamp representing the current moment
/// </summary>
/// <param name="ignored">Parameter ignored</param>
/// <returns>Now expressed as a Unix timestamp</returns>
public static int UnixTimestamp(this DateTime ignored)
{
    return (int)Math.Truncate((DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds);
}

Quickest (drops and creates all tables including data):

./manage.py reset appname | ./manage.py dbshell

Caution:

• Might not work on Windows correctly.
• Might keep some old tables in the db

This is what I did on windows.

1. Download a zip file that contains the open ssl exe from Google
2. Unpack the zip file and go into the bin folder.
3. Go to the address bar in the bin folder and type cmd. This will open a command prompt at this folder.
4. move/Put the .pem file into this bin folder.
5. Run two commands. One creates the cert and the second the key file

openssl x509 -outform der -in yourPemFilename.pem -out certfileOutName.crt
openssl rsa -in yourPemFilename.pem -out keyfileOutName.key

Found this thread looking for a solution to my problem. Mine required a different solution that I figured out that might be of use to others. My macro was deleting rows, shifting up, and copying rows to another worksheet. Memory usage was exploding to several gigs and causing "out of memory" after processing around only 4000 records. What solved it for me?

application.screenupdating = false

Added that at the beginning of my code (be sure to make it true again, at the end) I knew that would make it run faster, which it did.. but had no idea about the memory thing.

After making this small change the memory usage didn't exceed 135 mb. Why did that work? No idea really. But it's worth a shot and might apply to you.

Randomizing the array is intensive as you have to shift around a bunch of strings. Why not just randomly read from the array? In the worst case you could even create a wrapper class with a getNextString(). If you really do need to create a random array then you could do something like

for i = 0 -> i= array.length * 5
   swap two strings in random places

The *5 is arbitrary.

I realize this is an old question, but I use a much simpler way. Typically I just grab the list that I need, either by query or copying an existing list or whatever, then remove the duplicates. We will assume for this answer that your list is already in column C, row 4, as per the original question. This method works for whatever size list you have and you can select header yes or no.

Dim rng as range
Range("C4").Select
Set rng = Range(Selection, Selection.End(xlDown))
rng.RemoveDuplicates Columns:=1, Header:=xlYes

Use the PHP function

void set_time_limit ( int $seconds )

The maximum execution time, in seconds. If set to zero, no time limit is imposed.

This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini.

You can send a 400 Bad Request code. It's one of the more general-purpose 4xx status codes, so you can use it to mean what you intend: the client is sending a request that's missing information/parameters that your application requires in order to process it correctly.

If you want to extract the files to the respective folder you can try this

find . -name "*.zip" | while read filename; do unzip -o -d "`dirname "$filename"`" "$filename"; done;

A multi-processed version for systems that can handle high I/O:

find . -name "*.zip" | xargs -P 5 -I fileName sh -c 'unzip -o -d "$(dirname "fileName")/$(basename -s .zip "fileName")" "fileName"'

Addendum to @sjngm's answer:

They both also ignore whitespace:

var foo = "    3     ";
console.log(parseInt(foo)); // 3
console.log(Number(foo)); // 3

I'm slightly confused. You should be able to call sqlplus from within the bash script. This may be what you were doing with your first statement

Try Executing the following within your bash script:

#!/bin/bash          
echo Start Executing SQL commands
sqlplus <user>/<password> @file-with-sql-1.sql
sqlplus <user>/<password> @file-with-sql-2.sql

If you want to be able to pass data into your scripts you can do it via SQLPlus by passing arguments into the script:

Contents of file-with-sql-1.sql

 select * from users where username='&1';

Then change the bash script to call sqlplus passing in the value

#!/bin/bash

MY_USER=bob
sqlplus <user>/<password> @file-with-sql-1.sql $MY_USER

A txt File with PIPE (|) delimited file can be read as :

df = spark.read.option("sep", "|").option("header", "true").csv("s3://bucket_name/folder_path/file_name.txt")

I had to do something similar to Sean and ilalex's answer.
But I had too many options to explicitly define the sort order for and only needed to float certain entries to the front of the list ... in the specified (non-natural) order.
Hopefully this is helpful to someone else.

public class CarComparator implements Comparator<Car> {

    //sort these items in this order to the front of the list 
    private static List<String> ORDER = Arrays.asList("dd", "aa", "cc", "bb");

    public int compare(final Car o1, final Car o2) {
        int result = 0;
        int o1Index = ORDER.indexOf(o1.getName());
        int o2Index = ORDER.indexOf(o2.getName());
        //if neither are found in the order list, then do natural sort
        //if only one is found in the order list, float it above the other
        //if both are found in the order list, then do the index compare
        if (o1Index < 0 && o2Index < 0) result = o1.getName().compareTo(o2.getName());
        else if (o1Index < 0) result = 1;
        else if (o2Index < 0) result = -1;
        else result = o1Index - o2Index;
        return result;
    }

//Testing output: dd,aa,aa,cc,bb,bb,bb,a,aaa,ac,ac,ba,bd,ca,cb,cb,cd,da,db,dc,zz
}

I know you're using jQuery but for those who want a pure Javascript solution:

// Serialize form fields as URI argument/HTTP POST data
function serializeForm(form) {
    var kvpairs = [];
    for ( var i = 0; i < form.elements.length; i++ ) {
        var e = form.elements[i];
        if(!e.name || !e.value) continue; // Shortcut, may not be suitable for values = 0 (considered as false)
        switch (e.type) {
            case 'text':
            case 'textarea':
            case 'password':
            case 'hidden':
                kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            case 'radio':
            case 'checkbox':
                if (e.checked) kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            /*  To be implemented if needed:
            case 'select-one':
                ... document.forms[x].elements[y].options[0].selected ...
                break;
            case 'select-multiple':
                for (z = 0; z < document.forms[x].elements[y].options.length; z++) {
                    ... document.forms[x].elements[y].options[z].selected ...
                } */
                break;
        }
    }
    return kvpairs.join("&");
}

Another option is setting the log levels for specific tags:

adb logcat SensorService:S PowerManagerService:S NfcService:S power:I Sensors:E

If you just want to set the log levels for some tags you can do it on a tag by tag basis.

You can set the context to be poster or manually set fig_size.

import numpy as np
import seaborn as sns
import matplotlib.pyplot as plt

np.random.seed(0)
n, p = 40, 8
d = np.random.normal(0, 2, (n, p))
d += np.log(np.arange(1, p + 1)) * -5 + 10


# plot
sns.set_style('ticks')
fig, ax = plt.subplots()
# the size of A4 paper
fig.set_size_inches(11.7, 8.27)
sns.violinplot(data=d, inner="points", ax=ax)    
sns.despine()

fig.savefig('example.png')

I highly recommend reading the docs on the Intent.FLAG_ACTIVITY_CLEAR_TOP flag. Using it will not necessarily go back all the way to the first (main) activity. The flag will only remove all existing activities up to the activity class given in the Intent. This is explained well in the docs:

For example, consider a task consisting of the activities: A, B, C, D.
If D calls startActivity() with an Intent that resolves to the component of
activity B, then C and D will be finished and B receive the given Intent, 
resulting in the stack now being: A, B.

Note that the activity can set to be moved to the foreground (i.e., clearing all other activities on top of it), and then also being relaunched, or only get onNewIntent() method called.

Similar to Matthew's answer, I just found that you can do the following:

$(this).closest('form').submit();

Wrong: The problem with using the parent functionality is that the field needs to be immediately within the form to work (not inside tds, labels, etc).

I stand corrected: parents (with an s) also works. Thxs Paolo for pointing that out.

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

This is an IndexError in python, which means that we're trying to access an index which isn't there in the tensor. Below is a very simple example to understand this error.

# create an empty array of dimension `0`
In [14]: arr = np.array([], dtype=np.int64) 

# check its shape      
In [15]: arr.shape  
Out[15]: (0,)

with this array arr in place, if we now try to assign any value to some index, for example to the index 0 as in the case below

In [16]: arr[0] = 23     

Then, we will get an IndexError, as below:

---

IndexError                                Traceback (most recent call last)
<ipython-input-16-0891244a3c59> in <module>
----> 1 arr[0] = 23

IndexError: index 0 is out of bounds for axis 0 with size 0

The reason is that we are trying to access an index (here at 0^th position), which is not there (i.e. it doesn't exist because we have an array of size 0).

In [19]: arr.size * arr.itemsize  
Out[19]: 0

So, in essence, such an array is useless and cannot be used for storing anything. Thus, in your code, you've to follow the traceback and look for the place where you're creating an array/tensor of size 0 and fix that.

git checkout -b your-new-branch

git add <files>

git commit -m <message>

First, checkout your new branch. Then add all the files you want to commit to staging. Lastly, commit all the files you just added. You might want to do a git push origin your-new-branch afterward so your changes show up on the remote.

Check out the pack URI syntax. You want something like this:

<ResourceDictionary Source="pack://application:,,,/YourAssembly;component/Subfolder/YourResourceFile.xaml"/>

Just so I don't lose my answer that works:

1. Select the cell to copy
2. Select the final cell in the column
3. Press CTRL+D

IE.Document.getElementById("dgTime").getElementsByTagName("a")(0).Click

EDIT: to loop through the collection (items should appear in the same order as they are in the source document)

Dim links, link 

Set links = IE.Document.getElementById("dgTime").getElementsByTagName("a")

'For Each loop
For Each link in links
    link.Click
Next link

'For Next loop
Dim n, i
n = links.length
For i = 0 to n-1 Step 2
    links(i).click

The solution to the problem is already defined in some of the answers. But there is still a need to express a detail. The problem is totally related to maven, and the solution is also in the pom.xml configuration. IntelliJ only reads maven configuration, and if the configuration has wrong information, IntelliJ also tries to use that.

To solve the problem, as expressed in the most of the answers, just add the below properties to the pom.xml of the project.

<properties> 
      <maven.compiler.source>1.8</maven.compiler.source> 
      <maven.compiler.target>1.8</maven.compiler.target> 
</properties>

After that, on the IntelliJ side, reimport maven configuration. To reimport the maven configuration, right click on pom.xml file of the project and select Reimport. Compiler version related information in IntelliJ preferences will be automatically updated according to the values in the pom.xml.

use the HTML control with a runat server attribute

 <input id="FileInput" runat="server" type="file" />

Then in asp.net Codebehind

 FileInput.PostedFile.SaveAs("DestinationPath");

There are also some 3'rd party options that will show progress if you intrested

You can use a VBScript script wrapped in a BAT file. This code works on a relative PATH.

There isn't any need for any third-party tools or dependencies. Just set SOURCEDIR and OUTPUTZIP.

Filename: ZipUp.bat

echo Set fso = CreateObject("Scripting.FileSystemObject") > _zipup.vbs
echo InputFolder = fso.GetAbsolutePathName(WScript.Arguments.Item(0)) >> _zipup.vbs
echo ZipFile = fso.GetAbsolutePathName(WScript.Arguments.Item(1)) >> _zipup.vbs

' Create empty ZIP file.
echo CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" ^& Chr(5) ^& Chr(6) ^& String(18, vbNullChar) >> _zipup.vbs

echo Set objShell = CreateObject("Shell.Application") >> _zipup.vbs
echo Set source = objShell.NameSpace(InputFolder).Items >> _zipup.vbs
echo objShell.NameSpace(ZipFile).CopyHere(source) >> _zipup.vbs

echo ' Keep script waiting until compression is done
echo Do Until objShell.NameSpace( ZipFile ).Items.Count = objShell.NameSpace( InputFolder ).Items.Count >> _zipup.vbs
echo     WScript.Sleep 200 >> _zipup.vbs
echo Loop >> _zipup.vbs

CScript  _zipup.vbs  %SOURCEDIR%  %OUTPUTZIP%

del _zipup.vbs

Example usage

SET SOURCEDIR=C:\Some\Path
SET OUTPUTZIP=C:\Archive.zip
CALL ZipUp

Alternatively, you can parametrize this file by replacing the line CScript _zipup.vbs %SOURCEDIR% %OUTPUTZIP% with CScript _zipup.vbs %1 %2, in which case it can be even more easily called from by simply calling CALL ZipUp C:\Source\Dir C:\Archive.zip.

I agree with previous comment that might be best to consider a different approach. My suggest would be write a console application and use the windows scheduler:

This will:

• Reduce plumbing code that replicates scheduler behaviour
• Provide greater flexibility in terms of scheduling behaviour (e.g. only run on weekends) with all scheduling logic abstracted from application code
• Utilise the command line arguments for parameters without having to setup configuration values in config files etc
• Far easier to debug/test during development
• Allow a support user to execute by invoking the console application directly (e.g. useful during support situations)

EDIT (#1)

If I understand correctly, you wish to have everything in one page and execute it from the same page.

You can use the following code to send mail from a single page, for example index.php or contact.php

The only difference between this one and my original answer is the <form action="" method="post"> where the action has been left blank.

It is better to use header('Location: thank_you.php'); instead of echo in the PHP handler to redirect the user to another page afterwards.

Copy the entire code below into one file.

<?php 
if(isset($_POST['submit'])){
    $to = "[email protected]"; // this is your Email address
    $from = $_POST['email']; // this is the sender's Email address
    $first_name = $_POST['first_name'];
    $last_name = $_POST['last_name'];
    $subject = "Form submission";
    $subject2 = "Copy of your form submission";
    $message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
    $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];

    $headers = "From:" . $from;
    $headers2 = "From:" . $to;
    mail($to,$subject,$message,$headers);
    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
    // You can also use header('Location: thank_you.php'); to redirect to another page.
    }
?>

<!DOCTYPE html>
<head>
<title>Form submission</title>
</head>
<body>

<form action="" method="post">
First Name: <input type="text" name="first_name"><br>
Last Name: <input type="text" name="last_name"><br>
Email: <input type="text" name="email"><br>
Message:<br><textarea rows="5" name="message" cols="30"></textarea><br>
<input type="submit" name="submit" value="Submit">
</form>

</body>
</html> 

Original answer

I wasn't quite sure as to what the question was, but am under the impression that a copy of the message is to be sent to the person who filled in the form.

Here is a tested/working copy of an HTML form and PHP handler. This uses the PHP mail() function.

The PHP handler will also send a copy of the message to the person who filled in the form.

You can use two forward slashes // in front of a line of code if you're not going to use it.

For example: // $subject2 = "Copy of your form submission"; will not execute.

HTML FORM:

<!DOCTYPE html>
<head>
<title>Form submission</title>
</head>
<body>

<form action="mail_handler.php" method="post">
First Name: <input type="text" name="first_name"><br>
Last Name: <input type="text" name="last_name"><br>
Email: <input type="text" name="email"><br>
Message:<br><textarea rows="5" name="message" cols="30"></textarea><br>
<input type="submit" name="submit" value="Submit">
</form>

</body>
</html>

PHP handler (mail_handler.php)

(Uses info from HTML form and sends the Email)

<?php 
if(isset($_POST['submit'])){
    $to = "[email protected]"; // this is your Email address
    $from = $_POST['email']; // this is the sender's Email address
    $first_name = $_POST['first_name'];
    $last_name = $_POST['last_name'];
    $subject = "Form submission";
    $subject2 = "Copy of your form submission";
    $message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
    $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];

    $headers = "From:" . $from;
    $headers2 = "From:" . $to;
    mail($to,$subject,$message,$headers);
    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
    // You can also use header('Location: thank_you.php'); to redirect to another page.
    // You cannot use header and echo together. It's one or the other.
    }
?>

To send as HTML:

If you wish to send mail as HTML and for both instances, then you will need to create two separate sets of HTML headers with different variable names.

Read the manual on mail() to learn how to send emails as HTML:

• http://php.net/manual/en/function.mail.php

Footnotes:

• In regards to HTML5

You have to specify the URL of the service that will handle the submitted data, using the action attribute.

As outlined at https://www.w3.org/TR/html5/forms.html under 4.10.1.3 Configuring a form to communicate with a server. For complete information, consult the page.

Therefore, action="" will not work in HTML5.

The proper syntax would be:

• action="handler.xxx" or
• action="http://www.example.com/handler.xxx".

Note that xxx will be the extension of the type of file used to handle the process. This could be a .php, .cgi, .pl, .jsp file extension etc.

Consult the following Q&A on Stack if sending mail fails:

• PHP mail form doesn't complete sending e-mail

Here's an answer, based on (and I think an improvement on) Tester101's answer, expressed as a subroutine, with the CopyFile line once instead of three times, and prepared to handle changing the file name as the copy is made (no hard-coded destination directory). I also found I had to delete the target file before copying to get this to work, but that might be a Windows 7 thing. The WScript.Echo statements are because I didn't have a debugger and can of course be removed if desired.

Sub CopyFile(SourceFile, DestinationFile)

    Set fso = CreateObject("Scripting.FileSystemObject")

    'Check to see if the file already exists in the destination folder
    Dim wasReadOnly
    wasReadOnly = False
    If fso.FileExists(DestinationFile) Then
        'Check to see if the file is read-only
        If fso.GetFile(DestinationFile).Attributes And 1 Then 
            'The file exists and is read-only.
            WScript.Echo "Removing the read-only attribute"
            'Remove the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes - 1
            wasReadOnly = True
        End If

        WScript.Echo "Deleting the file"
        fso.DeleteFile DestinationFile, True
    End If

    'Copy the file
    WScript.Echo "Copying " & SourceFile & " to " & DestinationFile
    fso.CopyFile SourceFile, DestinationFile, True

    If wasReadOnly Then
        'Reapply the read-only attribute
        fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes + 1
    End If

    Set fso = Nothing

End Sub

I just was in about the same situation a day ago, and here are my 2 cents:

1) I found arguably the shortest and most concise demonstration of multiple model entry in single form here: http://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/ .

In a nutshell: Make a form for each model, submit them both to template in a single <form>, using prefix keyarg and have the view handle validation. If there is dependency, just make sure you save the "parent" model before dependant, and use parent's ID for foreign key before commiting save of "child" model. The link has the demo.

2) Maybe formsets can be beaten into doing this, but as far as I delved in, formsets are primarily for entering multiples of the same model, which may be optionally tied to another model/models by foreign keys. However, there seem to be no default option for entering more than one model's data and that's not what formset seems to be meant for.

array = [1,2,3,4,5]
def square(array):
    result = map(lambda x: x * x,array)
    return list(result)
print(square(array))

The easy way to do is, put all your files including index.html or something with all resources such as CSS, JS etc. in a folder public or you can name it whatever you want and now you can use express js and just tell app to use the _dirname as :

In your server.js using express add these

var express = require('express');
var app = express();
app.use(express.static(__dirname + '/public'));

and if you want to have seprate directory add new dir under public directory and use that path "/public/YourDirName"

SO what we are doing here exactly? we are creating express instance named app and we are giving the adress if the public directory to access all the resources. Hope this helps !

Go to project>clean and select the project which display error from check box and click ok , it will clear the error for you. Click the tab which display build automatically in the project menu And if this also does not work than restart the eclipse and try again it will work.

Further to @pmg's answer, note that you can do both operations in one statement:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++[strlen(p)-1] = 0;

This will likely work as expected but behavior is undefined in C standard.

I did it this way:

var xlApp = new Excel.Application();
var xlWorkBook = xlApp.Workbooks.Add(System.Reflection.Missing.Value);
var xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.Item[1];
xlWorkSheet.Columns.AutoFit();

With this way, columns always fit to text width inside cells.

Hope it helps to someone!

Use datetime module:

from datetime import datetime
ts = int("1284101485")

# if you encounter a "year is out of range" error the timestamp
# may be in milliseconds, try `ts /= 1000` in that case
print(datetime.utcfromtimestamp(ts).strftime('%Y-%m-%d %H:%M:%S'))

I know this post is getting outdated, but here's what they asked. In your style sheet:

.social {
    width: 330px;
    height: 75px;
    float: right;
    text-align: left;
    padding: 10px 0;
    border-bottom: dotted 1px #6d6d6d;
}
[class~="first"] {
    padding-top:0;
}
[class~="last"] {
    border:0;
}

But it may be a bad way to use selectors. Also, if you need multiple "first" extension, you'll have to be sure to set different name, or to refine your selector.

[class="social first"] {...}

I hope this will help someone, it can be pretty handy in some situation.

For exemple, if you have a tiny piece of css that has to be linked to many different components, and you don't want to write a hundred time the same code.

div.myClass1 {font-weight:bold;}
div.myClass2 {font-style:italic;}
...
div.myClassN {text-shadow:silver 1px 1px 1px;}

div.myClass1.red {color:red;}
div.myClass2.red {color:red;}
...
div.myClassN.red {color:red;}

Becomes:

div.myClass1 {font-weight:bold;}
div.myClass2 {font-style:italic;}
...
div.myClassN {text-shadow:silver 1px 1px 1px;}

[class~=red] {color:red;}

You could also try the dateparser module, which may be slower than datefinder on free text but which should cover more potential cases and date formats, as well as a significant number of languages.

//true / false
function isMobile()
{
   return (/Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent) ); 
}

also you can follow this tutorial to detect a specific mobile. Click here.

Lots of great answers here but they might be superseded by this CMake support in Visual Studio (Oct 5 2016)

Sass (Syntactically Awesome StyleSheets) have two syntaxes:

• a newer: SCSS (Sassy CSS)
• and an older, original: indent syntax, which is the original Sass and is also called Sass.

So they are both part of Sass preprocessor with two different possible syntaxes.

The most important difference between SCSS and original Sass:

SCSS:

• Syntax is similar to CSS (so much that every regular valid CSS3 is also valid SCSS, but the relationship in the other direction obviously does not happen)

• Uses braces {}

• Uses semi-colons ;
• Assignment sign is :
• To create a mixin it uses the @mixin directive
• To use mixin it precedes it with the @include directive
• Files have the .scss extension.

Original Sass:

• Syntax is similar to Ruby
• No braces
• No strict indentation
• No semi-colons
• Assignment sign is = instead of :
• To create a mixin it uses the = sign
• To use mixin it precedes it with the + sign
• Files have the .sass extension.

Some prefer Sass, the original syntax - while others prefer SCSS. Either way, but it is worth noting that Sass’s indented syntax has not been and will never be deprecated.

Conversions with sass-convert:

# Convert Sass to SCSS
$ sass-convert style.sass style.scss

# Convert SCSS to Sass
$ sass-convert style.scss style.sass

The Sass and SCSS documentation

As others have already shared, app.set('config', config) is great for this. I just wanted to add something that I didn't see in existing answers that is quite important. A Node.js instance is shared across all requests, so while it may be very practical to share some config or router object globally, storing runtime data globally will be available across requests and users. Consider this very simple example:

var express = require('express');
var app = express();

app.get('/foo', function(req, res) {
    app.set('message', "Welcome to foo!");
    res.send(app.get('message'));
});

app.get('/bar', function(req, res) {
    app.set('message', "Welcome to bar!");

    // some long running async function
    var foo = function() {
        res.send(app.get('message'));
    };
    setTimeout(foo, 1000);
});

app.listen(3000);

If you visit /bar and another request hits /foo, your message will be "Welcome to foo!". This is a silly example, but it gets the point across.

There are some interesting points about this at Why do different node.js sessions share variables?.

A lot (I would even say most) people do.

What's really important about exceptions, is that if you don't write any handling code - the result is perfectly safe and well-behaved. Too eager to panic, but safe.

You need to actively make mistakes in handlers to get something unsafe, and only catch(...){} will compare to ignoring error code.

NP-complete problems are those problems that are both NP-Hard and in the complexity class NP. Therefore, to show that any given problem is NP-complete, you need to show that the problem is both in NP and that it is NP-hard.

Problems that are in the NP complexity class can be solved non-deterministically in polynomial time and a possible solution (i.e., a certificate) for a problem in NP can be verified for correctness in polynomial time.

An example of a non-deterministic solution to the k-clique problem would be something like:

1) randomly select k nodes from a graph

2) verify that these k nodes form a clique.

The above strategy is polynomial in the size of the input graph and therefore the k-clique problem is in NP.

Note that all problems deterministically solvable in polynomial time are also in NP.

Showing that a problem is NP-hard typically involves a reduction from some other NP-hard problem to your problem using a polynomial time mapping: http://en.wikipedia.org/wiki/Reduction_(complexity)

Set your environmental variable Path to point to where the adb application is at: [directory of sdk folder]\platform-tools

Not too hard to explain... This is like typing hello worl, hitting the left-arrow key twice, typing d, and hitting the down-arrow key.

At least, that is how I infer your terminal is interpeting the \b and \n codes.

Redirect the output to a file and I bet you get something else entirely. Although you may have to look at the file's bytes to see the difference.

[edit]

To elaborate a bit, this printf emits a sequence of bytes: hello worl^H^Hd^J, where ^H is ASCII character #8 and ^J is ASCII character #10. What you see on your screen depends on how your terminal interprets those control codes.

Nothing beats a nice example

Think about your primary keys

Also think about your primary key. You can often use composite keys for relationships like this. Doctrine natively supports this. You can make your referenced entities into ids. Check the documentation on composite keys here

I also found myself in a similar position a couple of weeks ago. You can also do this by creating a custom ElementLocatorFactory (or simply passing in divA into the DefaultElementLocatorFactory) to see if it's a child of the first div - you would then call the appropriate PageFactory initElements method.

In this case if you did the following:

PageFactory.initElements(new DefaultElementLocatorFactory(divA), pageObjectInstance));
// The Page Object instance would then need a WebElement 
// annotated with something like the xpath above or @FindBy(tagName = "input")

I agree with all the performance and readability posts. However, there are cases where it really does matter. A couple other people mentioned this, but it might be easier to see with examples.

Consider this slightly modified example:

public static void main(String[] args) {
    String[] myNumberStrings = new String[] {"1.2345", "asdf", "2.3456"};
    ArrayList asNumbers = parseAll(myNumberStrings);
}

public static ArrayList parseAll(String[] numberStrings){
    ArrayList myFloats = new ArrayList();

    for(int i = 0; i < numberStrings.length; i++){
        myFloats.add(new Float(numberStrings[i]));
    }
    return myFloats;
}

If you want the parseAll() method to return null if there are any errors (like the original example), you'd put the try/catch on the outside like this:

public static ArrayList parseAll1(String[] numberStrings){
    ArrayList myFloats = new ArrayList();
    try{
        for(int i = 0; i < numberStrings.length; i++){
            myFloats.add(new Float(numberStrings[i]));
        }
    } catch (NumberFormatException nfe){
        //fail on any error
        return null;
    }
    return myFloats;
}

In reality, you should probably return an error here instead of null, and generally I don't like having multiple returns, but you get the idea.

On the other hand, if you want it to just ignore the problems, and parse whatever Strings it can, you'd put the try/catch on the inside of the loop like this:

public static ArrayList parseAll2(String[] numberStrings){
    ArrayList myFloats = new ArrayList();

    for(int i = 0; i < numberStrings.length; i++){
        try{
            myFloats.add(new Float(numberStrings[i]));
        } catch (NumberFormatException nfe){
            //don't add just this one
        }
    }

    return myFloats;
}

If you want really short one:

Based on Thilak's answer I was able to come up with this solution...

Since my form fields only show validation messages if a field is invalid, and has been touched by the user I was able to use this code triggered by a button to show my invalid fields:

// Show/trigger any validation errors for this step_x000D_
angular.forEach(vm.rfiForm.stepTwo.$error, function(error) {_x000D_
  angular.forEach(error, function(field) {_x000D_
    field.$setTouched();_x000D_
  });_x000D_
});_x000D_
// Prevent user from going to next step if current step is invalid_x000D_
if (!vm.rfiForm.stepTwo.$valid) {_x000D_
  isValid = false;_x000D_
}

<!-- form field -->_x000D_
<div class="form-group" ng-class="{ 'has-error': rfi.rfiForm.stepTwo.Parent_Suffix__c.$touched && rfi.rfiForm.stepTwo.Parent_Suffix__c.$invalid }">_x000D_
_x000D_
  <!-- field label -->_x000D_
  <label class="control-label">Suffix</label>_x000D_
  <!-- end field label -->_x000D_
  <!-- field input -->_x000D_
  <select name="Parent_Suffix__c" class="form-control"_x000D_
          ng-options="item.value as item.label for item in rfi.contact.Parent_Suffixes"_x000D_
          ng-model="rfi.contact.Parent_Suffix__c" />_x000D_
  <!-- end field input -->_x000D_
  <!-- field help -->_x000D_
  <span class="help-block" ng-messages="rfi.rfiForm.stepTwo.Parent_Suffix__c.$error" ng-show="rfi.rfiForm.stepTwo.Parent_Suffix__c.$touched">_x000D_
    <span ng-message="required">this field is required</span>_x000D_
  </span>  _x000D_
  <!-- end field help -->_x000D_
</div>_x000D_
<!-- end form field -->

Simply,
SELECT TIME(column_name), DATE(column_name)

$request->flash('request',$request);

<input type="text" class="form-control" name="name" value="{{ old('name') }}">

It works for me.

patrick dw's answer is right on.

For kicks and giggles I thought I would post a simple way to return an array of all the IDs.

var arrayOfIds = $.map($(".myClassName"), function(n, i){
  return n.id;
});
alert(arrayOfIds);

I'm a little confused about custom made completion handlers. In your example:

Say you have a download function to download a file from network,and want to be notified when download task has finished.

typealias CompletionHandler = (success:Bool) -> Void

func downloadFileFromURL(url: NSURL,completionHandler: CompletionHandler) {

    // download code.

    let flag = true // true if download succeed,false otherwise

    completionHandler(success: flag)
}

Your // download code will still be ran asynchronously. Why wouldn't the code go straight to your let flag = true and completion Handler(success: flag) without waiting for your download code to be finished?

To me it seems @atomicules has the simplest answer, but I think it can be simplified a little more. You need to put an @ before anything you want to be global, so that it compiles to this.anything and this refers to the global object.

so...

@bawbag = (x, y) ->
    z = (x * y)

bawbag(5, 10)

compiles to...

this.bawbag = function(x, y) {
  var z;
  return z = x * y;
};
bawbag(5, 10);

and works inside and outside of the wrapper given by node.js

(function() {
    this.bawbag = function(x, y) {
      var z;
      return z = x * y;
    };
    console.log(bawbag(5,13)) // works here
}).call(this);

console.log(bawbag(5,11)) // works here

They are both examples of floating point input/output.

%g and %G are simplifiers of the scientific notation floats %e and %E.

%g will take a number that could be represented as %f (a simple float or double) or %e (scientific notation) and return it as the shorter of the two.

The output of your print statement will depend on the value of sum.

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview

For me it only take to run these commands in my api directory:

rm -rf node_modules
npm cache clean 
npm install

if (/(^|;)\s*visited=/.test(document.cookie)) {
    alert("Hello again!");
} else {
    document.cookie = "visited=true; max-age=" + 60 * 60 * 24 * 10; // 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, and 10 days.
    alert("This is your first time!");
}

is one way to do it. Note that document.cookie is a magic property, so you don't have to worry about overwriting anything, either.

There are also more convenient libraries to work with cookies, and if you don’t need the information you’re storing sent to the server on every request, HTML5’s localStorage and friends are convenient and useful.

Using Virtual Attributes (Link to revised(paid) Railscast) you can store your price_in_cents in an integer column and add a virtual attribute price_in_dollars in your product model as a getter and setter.

# Add a price_in_cents integer column
$ rails g migration add_price_in_cents_to_products price_in_cents:integer

# Use virtual attributes in your Product model
# app/models/product.rb

def price_in_dollars
  price_in_cents.to_d/100 if price_in_cents
end

def price_in_dollars=(dollars)
  self.price_in_cents = dollars.to_d*100 if dollars.present?
end

Source: RailsCasts #016: Virtual Attributes: Virtual attributes are a clean way to add form fields that do not map directly to the database. Here I show how to handle validations, associations, and more.

This is an old question but a solution is still relevant. Here is my generic solution in Java 8 without using any third party library:

    T evaluate() throws Throwable;

    boolean shouldRetry(T t);

    private int increaseRetryCountAndSleep(int retries) {

If you're facing this issue with macOS Catalina, I recommend these steps:

1. Install Homebrew (if you haven't already done so): head over to brew.sh or simply run this command: /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Run brew install [email protected]

3. Update your $PATH variable to include the newly installed version of php:

echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc

echo 'export PATH="/usr/local/opt/[email protected]/sbin:$PATH"' >> ~/.zshrc

4. Reload your shell preferences script $ source ~/.zshrc or source ~/.bashrc

5. Finally, install laravel: composer global require laravel/installer

Try using the Worksheet.Protect method, like so:

Sub ProtectActiveSheet()
    Dim ws As Worksheet
    Set ws = ActiveSheet
    ws.Protect DrawingObjects:=True, Contents:=True, _
        Scenarios:=True, Password="SamplePassword"
End Sub

You should, however, be concerned about including the password in your VBA code. You don't necessarily need a password if you're only trying to put up a simple barrier that keeps a user from making small mistakes like deleting formulas, etc.

Also, if you want to see how to do certain things in VBA in Excel, try recording a Macro and looking at the code it generates. That's a good way to get started in VBA.

I use to detect Apple browser engine, this simple JavaScript condition:

 navigator.vendor.startsWith('Apple')

This is because you are executing the function not referencing it. You should do:

  setInterval(swapImages,1000);

Objects never go out of scope in C# as they do in C++. They are dealt with by the Garbage Collector automatically when they are not used anymore. This is a more complicated approach than C++ where the scope of a variable is entirely deterministic. CLR garbage collector actively goes through all objects that have been created and works out if they are being used.

An object can go "out of scope" in one function but if its value is returned, then GC would look at whether or not the calling function holds onto the return value.

Setting object references to null is unnecessary as garbage collection works by working out which objects are being referenced by other objects.

In practice, you don't have to worry about destruction, it just works and it's great :)

Dispose must be called on all objects that implement IDisposable when you are finished working with them. Normally you would use a using block with those objects like so:

using (var ms = new MemoryStream()) {
  //...
}

EDIT On variable scope. Craig has asked whether the variable scope has any effect on the object lifetime. To properly explain that aspect of CLR, I'll need to explain a few concepts from C++ and C#.

Actual variable scope

In both languages the variable can only be used in the same scope as it was defined - class, function or a statement block enclosed by braces. The subtle difference, however, is that in C#, variables cannot be redefined in a nested block.

In C++, this is perfectly legal:

int iVal = 8;
//iVal == 8
if (iVal == 8){
    int iVal = 5;
    //iVal == 5
}
//iVal == 8

In C#, however you get a a compiler error:

int iVal = 8;
if(iVal == 8) {
    int iVal = 5; //error CS0136: A local variable named 'iVal' cannot be declared in this scope because it would give a different meaning to 'iVal', which is already used in a 'parent or current' scope to denote something else
}

This makes sense if you look at generated MSIL - all the variables used by the function are defined at the start of the function. Take a look at this function:

public static void Scope() {
    int iVal = 8;
    if(iVal == 8) {
        int iVal2 = 5;
    }
}

Below is the generated IL. Note that iVal2, which is defined inside the if block is actually defined at function level. Effectively this means that C# only has class and function level scope as far as variable lifetime is concerned.

.method public hidebysig static void  Scope() cil managed
{
  // Code size       19 (0x13)
  .maxstack  2
  .locals init ([0] int32 iVal,
           [1] int32 iVal2,
           [2] bool CS$4$0000)

//Function IL - omitted
} // end of method Test2::Scope

C++ scope and object lifetime

Whenever a C++ variable, allocated on the stack, goes out of scope it gets destructed. Remember that in C++ you can create objects on the stack or on the heap. When you create them on the stack, once execution leaves the scope, they get popped off the stack and gets destroyed.

if (true) {
  MyClass stackObj; //created on the stack
  MyClass heapObj = new MyClass(); //created on the heap
  obj.doSomething();
} //<-- stackObj is destroyed
//heapObj still lives

When C++ objects are created on the heap, they must be explicitly destroyed, otherwise it is a memory leak. No such problem with stack variables though.

C# Object Lifetime

In CLR, objects (i.e. reference types) are always created on the managed heap. This is further reinforced by object creation syntax. Consider this code snippet.

MyClass stackObj;

In C++ this would create an instance on MyClass on the stack and call its default constructor. In C# it would create a reference to class MyClass that doesn't point to anything. The only way to create an instance of a class is by using new operator:

MyClass stackObj = new MyClass();

In a way, C# objects are a lot like objects that are created using new syntax in C++ - they are created on the heap but unlike C++ objects, they are managed by the runtime, so you don't have to worry about destructing them.

Since the objects are always on the heap the fact that object references (i.e. pointers) go out of scope becomes moot. There are more factors involved in determining if an object is to be collected than simply presence of references to the object.

C# Object references

Jon Skeet compared object references in Java to pieces of string that are attached to the balloon, which is the object. Same analogy applies to C# object references. They simply point to a location of the heap that contains the object. Thus, setting it to null has no immediate effect on the object lifetime, the balloon continues to exist, until the GC "pops" it.

Continuing down the balloon analogy, it would seem logical that once the balloon has no strings attached to it, it can be destroyed. In fact this is exactly how reference counted objects work in non-managed languages. Except this approach doesn't work for circular references very well. Imagine two balloons that are attached together by a string but neither balloon has a string to anything else. Under simple ref counting rules, they both continue to exist, even though the whole balloon group is "orphaned".

.NET objects are a lot like helium balloons under a roof. When the roof opens (GC runs) - the unused balloons float away, even though there might be groups of balloons that are tethered together.

.NET GC uses a combination of generational GC and mark and sweep. Generational approach involves the runtime favouring to inspect objects that have been allocated most recently, as they are more likely to be unused and mark and sweep involves runtime going through the whole object graph and working out if there are object groups that are unused. This adequately deals with circular dependency problem.

Also, .NET GC runs on another thread(so called finalizer thread) as it has quite a bit to do and doing that on the main thread would interrupt your program.

There's Pgloader that uses the aforementioned COPY command and which can load data from csv (and MySQL, SQLite and dBase). It's also using separate threads for reading and copying data, so it's quite fast (interestingly enough, it got written from Python to Common Lisp and got a 20 to 30x speed gain, see blog post).

To load the csv file one needs to write a little configuration file, like

LOAD CSV  
  FROM 'path/to/file.csv' (x, y, a, b, c, d)  
  INTO postgresql:///pgloader?csv (a, b, d, c)  
  …

This command installs npm package username/package from specific git commit:

npm install https://github.com/username/package#3d0a21cc

Here 3d0a21cc is first 8 characters of commit hash.

I think with np.array() you can only create C like though you mention the order, when you check using np.isfortran() it says false. but with np.ndarrray() when you specify the order it creates based on the order provided.

For me the issue was network connection, once I reconnected to my wifi, it could fetch the details and commit without any issues.

None of these solutions worked. only changing the workspace worked for me.

You could catch the NullPointerException explicitly and ignore it - though its generally not recommended. You should not, however, ignore all exceptions as you're currently doing.

UserInfo ui = new UserInfo();
try {
    DirectoryUser du = LDAPService.findUser(username);
    if (du!=null) {
       ui.setUserInfo(du.getUserInfo());
    }
} catch (NullPointerException npe) {
    // Lulz @ your NPE
    Logger.log("No user info for " +username+ ", will find some way to cope");
}

insert into account_type_standard (account_type_Standard_id, tax_status_id, recipient_id)
select account_type_standard_seq.nextval,
   ts.tax_status_id, 
   ( select r.recipient_id
     from recipient r
     where r.recipient_code = ?
   )
from tax_status ts
where ts.tax_status_code = ?

You need to use the fn:contains() or fn:containsIgnoreCase() function.

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

...

 <c:if test="${not fn:containsIgnoreCase(mylist, 'apple')}">
        <p>Doesn't contain 'apple'</p>
    </c:if>

or

<c:if test="${not fn:contains(mylist, 'Apple')}">
            <p>Contains 'Apple'</p>
        </c:if>

Note: This will work like mylist.toString().contains("apple") and if this is not what you are looking for better use a other approach.

You have to install npm install env-cmd

Make .env in the root directory and update like this & REACT_APP_ is the compulsory prefix for the variable name.

REACT_APP_NODE_ENV="production"
REACT_APP_DB="http://localhost:5000"

Update package.json

  "scripts": {
    "start": "env-cmd react-scripts start",
    "build": "env-cmd react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

select to_number(exception_value) from exception where to_number(exception_value) = 105

Using this implementation you just have to give epoch time as a parameter and you will the output as (1 second ago, 2 minutes ago, and so on).

func setTimestamp(epochTime: String) -> String {
    let currentDate = Date()
    let epochDate = Date(timeIntervalSince1970: TimeInterval(epochTime) as! TimeInterval)

    let calendar = Calendar.current

    let currentDay = calendar.component(.day, from: currentDate)
    let currentHour = calendar.component(.hour, from: currentDate)
    let currentMinutes = calendar.component(.minute, from: currentDate)
    let currentSeconds = calendar.component(.second, from: currentDate)

    let epochDay = calendar.component(.day, from: epochDate)
    let epochMonth = calendar.component(.month, from: epochDate)
    let epochYear = calendar.component(.year, from: epochDate)
    let epochHour = calendar.component(.hour, from: epochDate)
    let epochMinutes = calendar.component(.minute, from: epochDate)
    let epochSeconds = calendar.component(.second, from: epochDate)

    if (currentDay - epochDay < 30) {
        if (currentDay == epochDay) {
            if (currentHour - epochHour == 0) {
                if (currentMinutes - epochMinutes == 0) {
                    if (currentSeconds - epochSeconds <= 1) {
                        return String(currentSeconds - epochSeconds) + " second ago"
                    } else {
                        return String(currentSeconds - epochSeconds) + " seconds ago"
                    }

                } else if (currentMinutes - epochMinutes <= 1) {
                    return String(currentMinutes - epochMinutes) + " minute ago"
                } else {
                    return String(currentMinutes - epochMinutes) + " minutes ago"
                }
            } else if (currentHour - epochHour <= 1) {
                return String(currentHour - epochHour) + " hour ago"
            } else {
                return String(currentHour - epochHour) + " hours ago"
            }
        } else if (currentDay - epochDay <= 1) {
            return String(currentDay - epochDay) + " day ago"
        } else {
            return String(currentDay - epochDay) + " days ago"
        }
    } else {
        return String(epochDay) + " " + getMonthNameFromInt(month: epochMonth) + " " + String(epochYear)
    }
}


func getMonthNameFromInt(month: Int) -> String {
    switch month {
    case 1:
        return "Jan"
    case 2:
        return "Feb"
    case 3:
        return "Mar"
    case 4:
        return "Apr"
    case 5:
        return "May"
    case 6:
        return "Jun"
    case 7:
        return "Jul"
    case 8:
        return "Aug"
    case 9:
        return "Sept"
    case 10:
        return "Oct"
    case 11:
        return "Nov"
    case 12:
        return "Dec"
    default:
        return ""
    }
}

How to call?

setTimestamp(epochTime: time) and you'll get the desired output as a string.

• Inner join - An inner join using either of the equivalent queries gives the intersection of the two tables, i.e. the two rows they have in common.

• Left outer join - A left outer join will give all rows in A, plus any common rows in B.

• Full outer join - A full outer join will give you the union of A and B, i.e. All the rows in A and all the rows in B. If something in A doesn't have a corresponding datum in B, then the B portion is null, and vice versay

When I add @ComponentScan("com.firstday.spring.boot.services") or scanBasePackages{"com.firstday.spring.boot.services"} jsp is not loaded. So when I add the parent package of project in @SpringBootApplication class it's working fine in my case

Code Example:-

package com.firstday.spring.boot.firstday;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(scanBasePackages = {"com.firstday.spring.boot"})
public class FirstDayApplication {

    public static void main(String[] args) {
        SpringApplication.run(FirstDayApplication.class, args);
    }

}

Not sure if anyone post this. Found this solution simple to use!. The SoftKeyboard class is on gist.github.com. But while keyboard popup/hide event callback we need a handler to properly do things on UI:

/*
Somewhere else in your code
*/
RelativeLayout mainLayout = findViewById(R.layout.main_layout); // You must use your root layout
InputMethodManager im = (InputMethodManager) getSystemService(Service.INPUT_METHOD_SERVICE);

/*
Instantiate and pass a callback
*/
SoftKeyboard softKeyboard;
softKeyboard = new SoftKeyboard(mainLayout, im);
softKeyboard.setSoftKeyboardCallback(new SoftKeyboard.SoftKeyboardChanged()
{

    @Override
    public void onSoftKeyboardHide() 
    {
        // Code here
        new Handler(Looper.getMainLooper()).post(new Runnable() {
                @Override
                public void run() {
                    // Code here will run in UI thread
                    ...
                }
            });
    }

    @Override
    public void onSoftKeyboardShow() 
    {
        // Code here
        new Handler(Looper.getMainLooper()).post(new Runnable() {
                @Override
                public void run() {
                    // Code here will run in UI thread
                    ...
                }
            });

    }   
});

 jQuery( function($){
    // add multiple select / deselect functionality
    $("#contact_select_all").click(function () {

        if($("#contact_select_all").is(":checked")){
            $('.noborder').prop('checked',true);
        }else
            $('.noborder').prop('checked',false);
    });

    // if all checkbox are selected, check the selectall checkbox
    $(".noborder").click(function(){

    if($(".noborder").length == $(".noborder:checked").length) {
        $("#contact_select_all").attr("checked", "checked");
    } else {
        $("#contact_select_all").removeAttr("checked");
    }

    });

});

DECLARE @DateTime DATETIME
SET @DateTime = '2018-11-23 10:03:23'
SELECT CONVERT(VARCHAR(100),@DateTime,121 )

I used the solution @Alex Martelli suggests, but it fails

TypeError 'bool' object does not support item assignment

when the two dictionaries differ in data type at some level.

In case at the same level the element of dictionary d is just a scalar (ie. Bool) while the element of dictionary u is still dictionary the reassignment fails as no dictionary assignment is possible into scalar (like True[k]).

One added condition fixes that:

from collections import Mapping

def update_deep(d, u):
    for k, v in u.items():
        # this condition handles the problem
        if not isinstance(d, Mapping):
            d = u
        elif isinstance(v, Mapping):
            r = update_deep(d.get(k, {}), v)
            d[k] = r
        else:
            d[k] = u[k]

    return d

The code you posted looks like it should correctly remove the forms authentication token, so it is possible that the folders/pages in question are not actually protected.

Have you confirmed that the pages cannot be accessed before a login has occured?

Can you post the web.config settings and login code that you are using?

Change draggable attribute from

<span draggable="true">Label</span>

to

<span draggable="false">Label</span>

You may be able to use absolute positioning.

The container box should be set to position: relative.

The top-right text should be set to position: absolute; top: 0; right: 0. The bottom-right text should be set to position: absolute; bottom: 0; right: 0.

You'll need to experiment with padding to stop the main contents of the box from running underneath the absolute positioned elements, as they exist outside the normal flow of the text contents.

You can use:

MYSTRING="abc123"
MYLENGTH=$(printf "%s" "$MYSTRING" | wc -c)

• wc -c or wc --bytes for byte counts = Unicode characters are counted with 2, 3 or more bytes.
• wc -m or wc --chars for character counts = Unicode characters are counted single until they use more bytes.

In Java script you declare array as below:

var array=[];
array.push();

and for arraylist or object or array you have to use json; and Serialize it using json by using following code:

 var serializedMyObj = JSON.stringify(myObj);

well you could do this, but it's not esp general

'I pity the $fool'.replace('$fool', 'fool')

You could easily write a function that does this intelligently if you really needed to

Did you import it? Importing matplotlib is not enough.

>>> import matplotlib
>>> matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'

but

>>> import matplotlib.pyplot
>>> matplotlib.pyplot

works.

pyplot is a submodule of matplotlib and not immediately imported when you import matplotlib.

The most common form of importing pyplot is

import matplotlib.pyplot as plt

Thus, your statements won't be too long, e.g.

plt.plot([1,2,3,4,5])

instead of

matplotlib.pyplot.plot([1,2,3,4,5])

And: pyplot is not a function, it's a module! So don't call it, use the functions defined inside this module instead. See my example above

start cmd /k "your cmd command1"
start cmd /k "your cmd command2"

It works in Windows server2012 while I use these command in one batch file.

You should use the controller in the directive and ng-click in the template html, as suggested previous responses. However, if you need to do DOM manipulation upon the event(click), such as on click of the button, you want to change the color of the button or so, then use the Link function and use the element to manipulate the dom.

If all you want to do is show some value on an HTML element or any such non-dom manipulative task, then you may not need a directive, and can directly use the controller.

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

Supply the public rsa key of the host :-

String knownHostPublicKey = "mywebsite.com ssh-rsa AAAAB3NzaC1.....XL4Jpmp/";

session.setKnownHosts(new ByteArrayInputStream(knownHostPublicKey.getBytes()));

He who is Shy^* gave you the germ of an answer, but only the germ. The basic technique for converting a value into a string in the C pre-processor is indeed via the '#' operator, but a simple transliteration of the proposed solution gets a compilation error:

#define TEST_FUNC test_func
#define TEST_FUNC_NAME #TEST_FUNC

#include <stdio.h>
int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

The syntax error is on the 'puts()' line - the problem is a 'stray #' in the source.

In section 6.10.3.2 of the C standard, 'The # operator', it says:

Each # preprocessing token in the replacement list for a function-like macro shall be followed by a parameter as the next preprocessing token in the replacement list.

The trouble is that you can convert macro arguments to strings -- but you can't convert random items that are not macro arguments.

So, to achieve the effect you are after, you most certainly have to do some extra work.

#define FUNCTION_NAME(name) #name
#define TEST_FUNC_NAME  FUNCTION_NAME(test_func)

#include <stdio.h>

int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

I'm not completely clear on how you plan to use the macros, and how you plan to avoid repetition altogether. This slightly more elaborate example might be more informative. The use of a macro equivalent to STR_VALUE is an idiom that is necessary to get the desired result.

#define STR_VALUE(arg)      #arg
#define FUNCTION_NAME(name) STR_VALUE(name)

#define TEST_FUNC      test_func
#define TEST_FUNC_NAME FUNCTION_NAME(TEST_FUNC)

#include <stdio.h>

static void TEST_FUNC(void)
{
    printf("In function %s\n", TEST_FUNC_NAME);
}

int main(void)
{
    puts(TEST_FUNC_NAME);
    TEST_FUNC();
    return(0);
}

You can simply use the powerful .loc method and use one condition or several depending on your need (tested with pandas=1.0.5).

Code Summary:

df=pd.DataFrame(dict(Type='A B B C'.split(), Set='Z Z X Y'.split()))
df['Color'] = "red"
df.loc[(df['Set']=="Z"), 'Color'] = "green"

#practice!
df.loc[(df['Set']=="Z")&(df['Type']=="B")|(df['Type']=="C"), 'Color'] = "purple"

Explanation:

df=pd.DataFrame(dict(Type='A B B C'.split(), Set='Z Z X Y'.split()))

# df so far: 
  Type Set  
0    A   Z 
1    B   Z 
2    B   X 
3    C   Y

add a 'color' column and set all values to "red"

df['Color'] = "red"

Apply your single condition:

df.loc[(df['Set']=="Z"), 'Color'] = "green"


# df: 
  Type Set  Color
0    A   Z  green
1    B   Z  green
2    B   X    red
3    C   Y    red

or multiple conditions if you want:

df.loc[(df['Set']=="Z")&(df['Type']=="B")|(df['Type']=="C"), 'Color'] = "purple"

Go to VS_CODE_FOLDER/resources/app/extensions/ and there update package.json

You can leave action attribute blank. The form will automatically submit itself in the same page.

<form action="">

According to the w3c specification, action attribute must be non-empty valid url in general. There is also an explanation for some situations in which the action attribute may be left empty.

The action of an element is the value of the element’s formaction attribute, if the element is a Submit Button and has such an attribute, or the value of its form owner’s action attribute, if it has one, or else the empty string.

So they both still valid and works:

<form action="">
<form action="FULL_URL_STRING_OF_CURRENT_PAGE">

If you are sure your audience is using html5 browsers, you can even omit the action attribute:

<form>

String text = "In early March, the city of Topeka, Kansas," + "<br>" +
              "temporarily changed its name to Google..." + "<br>" + "<br>" +
              "...in an attempt to capture a spot" + "<br>" +
              "in Google's new broadband/fiber-optics project." + "<br>" + "<br>" +"<br>" +
              "source: http://en.wikipedia.org/wiki/Google_server#Oil_Tanker_Data_Center";
JLabel label = new JLabel("<html><div style='text-align: center;'>" + text + "</div></html>");

If you would like to do your filtering in LINQ, you can do it like this:

var ext = new List<string> { "jpg", "gif", "png" };
var myFiles = Directory
    .EnumerateFiles(dir, "*.*", SearchOption.AllDirectories)
    .Where(s => ext.Contains(Path.GetExtension(s).TrimStart(".").ToLowerInvariant()));

Now ext contains a list of allowed extensions; you can add or remove items from it as necessary for flexible filtering.

I struggled for days. I tried all the different configurations suggested in this thread. None of them works. Finally, I find only the important configuration is the prepare-agent goal. But you have to put it in the right phase. I saw so many examples put it in the "pre-integration-test", that's a misleading, as it will only be executed after unit test. So the unit test won't be instrumented.

The right config should just use the default phase, (don't specify the phase explicitly). And usually, you don't need to mass around maven-surefire-plugin.

  <plugin>

To submit a single file, you can simply use the File object from the input's .files array directly as the value of body: in your fetch() initializer:

const myInput = document.getElementById('my-input');

// Later, perhaps in a form 'submit' handler or the input's 'change' handler:
fetch('https://example.com/some_endpoint', {
  method: 'POST',
  body: myInput.files[0],
});

This works because File inherits from Blob, and Blob is one of the permissible BodyInit types defined in the Fetch Standard.

Initially I used object in useState, but then I moved to useReducer hook for complex cases. I felt a performance improvement when I refactored the code.

useReducer is usually preferable to useState when you have complex state logic that involves multiple sub-values or when the next state depends on the previous one.

useReducer React docs

I already implemented such hook for my own use:

/**
 * Same as useObjectState but uses useReducer instead of useState
 *  (better performance for complex cases)
 * @param {*} PropsWithDefaultValues object with all needed props 
 * and their initial value
 * @returns [state, setProp] state - the state object, setProp - dispatch 
 * changes one (given prop name & prop value) or multiple props (given an 
 * object { prop: value, ...}) in object state
 */
export function useObjectReducer(PropsWithDefaultValues) {
  const [state, dispatch] = useReducer(reducer, PropsWithDefaultValues);

  //newFieldsVal={[field_name]: [field_value], ...}
  function reducer(state, newFieldsVal) {
    return { ...state, ...newFieldsVal };
  }

  return [
    state,
    (newFieldsVal, newVal) => {
      if (typeof newVal !== "undefined") {
        const tmp = {};
        tmp[newFieldsVal] = newVal;
        dispatch(tmp);
      } else {
        dispatch(newFieldsVal);
      }
    },
  ];
}

You just need to overwrite what you're deleting with the next value in the array, propagate that change, and then keep in mind where the new end is:

int array[] = {1, 2, 3, 4, 5, 6, 7, 8, 9};

// delete 3 (index 2)
for (int i = 2; i < 8; ++i)
    array[i] = array[i + 1]; // copy next element left

Now your array is {1, 2, 4, 5, 6, 7, 8, 9, 9}. You cannot delete the extra 9 since this is a statically-sized array, you just have to ignore it. This can be done with std::copy:

std::copy(array + 3, // copy everything starting here
          array + 9, // and ending here, not including it,
          array + 2) // to this destination

In C++11, use can use std::move (the algorithm overload, not the utility overload) instead.

More generally, use std::remove to remove elements matching a value:

// remove *all* 3's, return new ending (remaining elements unspecified)
auto arrayEnd = std::remove(std::begin(array), std::end(array), 3);

Even more generally, there is std::remove_if.

Note that the use of std::vector<int> may be more appropriate here, as its a "true" dynamically-allocated resizing array. (In the sense that asking for its size() reflects removed elements.)

Hi First write the Activity class. The following class have a Name of category and small add button. When you press on add (+) button it adds the new row which contains an EditText and an ImageButton which performs the delete of the row.

3. Once you finished your view will as shown below

It's possible that other tables have FK constraint to your [table]. So the DB needs to check these tables to maintain the referential integrity. Even if you have all needed indexes corresponding these FKs, check their amount.

I had the situation when NHibernate incorrectly created duplicated FKs on the same columns, but with different names (which is allowed by SQL Server). It has drastically slowed down running of the DELETE statement.

Below is the code that Bootstrap uses. Colors are bit different but the concept is same. This is if you are using LESS to compile CSS:

// Form control focus state
//
// Generate a customized focus state and for any input with the specified color,
// which defaults to the `@input-focus-border` variable.
//
// We highly encourage you to not customize the default value, but instead use
// this to tweak colors on an as-needed basis. This aesthetic change is based on
// WebKit's default styles, but applicable to a wider range of browsers. Its
// usability and accessibility should be taken into account with any change.
//
// Example usage: change the default blue border and shadow to white for better
// contrast against a dark gray background.

.form-control-focus(@color: @input-border-focus) {
  @color-rgba: rgba(red(@color), green(@color), blue(@color), .6);
  &:focus {
    border-color: @color;
    outline: 0;
    .box-shadow(~"inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px @{color-rgba}");
  }
}

If you are not using LESS then here's the compiled version:

.form-control:focus {
    border-color: #66afe9;
    outline: 0;
    -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
    box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
}

(a) Django is a framework, not a language

(b) I'm not sure what you're missing - there is no reason why you can't have business logic in a web application. In Django, you would normally expect presentation logic to be separated from business logic. Just because it is hosted in the same application server, it doesn't follow that the two layers are entangled.

(c) Django does provide templating, but it doesn't provide rich libraries for generating client-side content.

I used this solution and it worked with Font Awesome 5: https://stackoverflow.com/a/50973559/3813846

What made the difference in my case was to add font-weight: 900;to the class. Keep in mind to 'fa' to the value.

Example of my code:

<select class="text-primary fa-select" name="class_logo" required>
  <option value="fa address-book">&#xf2b9; address-book</option>
  <option value="fa adjust">&#xf042; adjust</option>
  <option value="fa air-freshener">&#xf5d0; air-freshener</option>
</select>

CSS:

.fa-select {
    font-family: 'Lato', 'Font Awesome 5 Free';
    font-weight: 900;
}

Edit: If you are mixing Solid Icons with Brand Icons in the select, change the CSS as follows:

.fa-select {
    font-family: 'Lato', 'Font Awesome 5 Free', 'Font Awesome 5 Brands';
    font-weight: 900;
}

your max factor is not more than your number, so, let's say

def factors(n):
    factors = []
    for i in range(1, n//2+1):
        if n % i == 0:
            factors.append (i)
    factors.append(n)

    return factors

voilá!

In short:

someValues.forEach((element) => {
    console.log(element);
});

If you care about index, then second parameter can be passed to receive the index of current element:

someValues.forEach((element, index) => {
    console.log(`Current index: ${index}`);
    console.log(element);
});

Refer here to know more about Array of ES6: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array

You can't checkout a single directory of a repository because the entire repository is handled by the single .git folder in the root of the project instead of subversion's myriad of .svn directories.

The problem with working on plugins in a single repository is that making a commit to, e.g., mytheme will increment the revision number for myplugin, so even in subversion it is better to use separate repositories.

The subversion paradigm for sub-projects is svn:externals which translates somewhat to submodules in git (but not exactly in case you've used svn:externals before.)

You will have to use something like below

#menu ul{_x000D_
  list-style: none;_x000D_
}_x000D_
#menu li{_x000D_
  display: inline;_x000D_
}_x000D_
 

<div id="menu">_x000D_
  <ul>_x000D_
    <li>First menu item</li>_x000D_
    <li>Second menu item</li>_x000D_
    <li>Third menu item</li>_x000D_
  </ul>_x000D_
</div>

Every SQL batch has to fit in the Batch Size Limit: 65,536 * Network Packet Size.

Other than that, your query is limited by runtime conditions. It will usually run out of stack size because x IN (a,b,c) is nothing but x=a OR x=b OR x=c which creates an expression tree similar to x=a OR (x=b OR (x=c)), so it gets very deep with a large number of OR. SQL 7 would hit a SO at about 10k values in the IN, but nowdays stacks are much deeper (because of x64), so it can go pretty deep.

Update

You already found Erland's article on the topic of passing lists/arrays to SQL Server. With SQL 2008 you also have Table Valued Parameters which allow you to pass an entire DataTable as a single table type parameter and join on it.

XML and XPath is another viable solution:

SELECT ...
FROM Table
JOIN (
   SELECT x.value(N'.',N'uniqueidentifier') as guid
   FROM @values.nodes(N'/guids/guid') t(x)) as guids
 ON Table.guid = guids.guid;

For Spring Boot >= 1.4

@Configuration
public class AppConfig
{
    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) 
    {
        return restTemplateBuilder
           .setConnectTimeout(...)
           .setReadTimeout(...)
           .build();
    }
}

For Spring Boot <= 1.3

@Configuration
public class AppConfig
{
    @Bean
    @ConfigurationProperties(prefix = "custom.rest.connection")
    public HttpComponentsClientHttpRequestFactory customHttpRequestFactory() 
    {
        return new HttpComponentsClientHttpRequestFactory();
    }

    @Bean
    public RestTemplate customRestTemplate()
    {
        return new RestTemplate(customHttpRequestFactory());
    }
}

then in your application.properties

custom.rest.connection.connection-request-timeout=...
custom.rest.connection.connect-timeout=...
custom.rest.connection.read-timeout=...

This works because HttpComponentsClientHttpRequestFactory has public setters connectionRequestTimeout, connectTimeout, and readTimeout and @ConfigurationProperties sets them for you.

For Spring 4.1 or Spring 5 without Spring Boot using @Configuration instead of XML

@Configuration
public class AppConfig
{
    @Bean
    public RestTemplate customRestTemplate()
    {
        HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory();
        httpRequestFactory.setConnectionRequestTimeout(...);
        httpRequestFactory.setConnectTimeout(...);
        httpRequestFactory.setReadTimeout(...);

        return new RestTemplate(httpRequestFactory);
    }
}

What do you mean costs too much? Too much what?

SELECT MAX(Balance) AS MaxBalance, CustomerID FROM CUSTOMERS GROUP BY CustomerID

If your table is properly indexed (Balance) and there has got to be an index on the PK than I am not sure what you mean about costs too much or seems unreliable? There is nothing unreliable about an aggregate that you are using and telling it to do. In this case, MAX() does exactly what you tell it to do - there's nothing magical about it.

Take a look at MAX() and if you want to filter it use the HAVING clause.

Depends, where you want to have the vertical line, but if you want a vertical border for example, you can have the parent view have a background a custom drawable. And you can then define the drawable like this:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape
            android:shape="rectangle">
            <stroke android:width="1dp" android:color="#000000" />
            <solid android:color="#00ffffff" />

        </shape>
    </item>

    <item android:right="1dp">
        <shape android:shape="rectangle">
            <solid android:color="#00ffffff" />
        </shape>
    </item>

</layer-list>

This example will create a 1dp thin black line on the right side of the view, that will have this drawable as an background.

You could do this two different ways. One is by using "as"

has_many :tasks, :as => :jobs

or

def jobs
     self.tasks
end

Obviously the first one would be the best way to handle it.

echo append a carriage return at the end.

Use

echo -e

to remove the extra 0x0A

Also, hexdump does not work byte-per-byte as default. This is why it shows you bytes in a weird endianess and why it shows you an extra 0x00.

For those looking to add an item to a json collection

function save(item, path = './collection.json'){
    if (!fs.existsSync(path)) {
        fs.writeFile(path, JSON.stringify([item]));
    } else {
        var data = fs.readFileSync(path, 'utf8');  
        var list = (data.length) ? JSON.parse(data): [];
        if (list instanceof Array) list.push(item)
        else list = [item]  
        fs.writeFileSync(path, JSON.stringify(list));
    }
}

The best way to set/get the value of a textarea is the .val(), .value method.

.text() internally uses the .textContent (or .innerText for IE) method to get the contents of a <textarea>. The following test cases illustrate how text() and .val() relate to each other:

var t = '<textarea>';
console.log($(t).text('test').val());             // Prints test
console.log($(t).val('too').text('test').val());  // Prints too
console.log($(t).val('too').text());              // Prints nothing
console.log($(t).text('test').val('too').val());  // Prints too

console.log($(t).text('test').val('too').text()); // Prints test

The value property, used by .val() always shows the current visible value, whereas text()'s return value can be wrong.

Python comes with a small utility that does just this. From the command line run:

Make sure you close the command window (with exit or the close button) and open it again.

The main method is the entry point of a Java application.

Specifically?when the Java Virtual Machine is told to run an application by specifying its class (by using the java application launcher), it will look for the main method with the signature of public static void main(String[]).

From Sun's java command page:

The java tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.

The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter. The method declaration must look like the following:

public static void main(String args[])

For additional resources on how an Java application is executed, please refer to the following sources:

1. Chapter 12: Execution from the Java Language Specification, Third Edition.
2. Chapter 5: Linking, Loading, Initializing from the Java Virtual Machine Specifications, Second Edition.
3. A Closer Look at the "Hello World" Application from the Java Tutorials.

The run method is the entry point for a new Thread or an class implementing the Runnable interface. It is not called by the Java Virutal Machine when it is started up by the java command.

As a Thread or Runnable itself cannot be run directly by the Java Virtual Machine, so it must be invoked by the Thread.start() method. This can be accomplished by instantiating a Thread and calling its start method in the main method of the application:

public class MyRunnable implements Runnable
{
    public void run()
    {
        System.out.println("Hello World!");
    }

    public static void main(String[] args)
    {
        new Thread(new MyRunnable()).start();
    }
}

For more information and an example of how to start a subclass of Thread or a class implementing Runnable, see Defining and Starting a Thread from the Java Tutorials.

The init method is the first method called in an Applet or JApplet.

When an applet is loaded by the Java plugin of a browser or by an applet viewer, it will first call the Applet.init method. Any initializations that are required to use the applet should be executed here. After the init method is complete, the start method is called.

For more information about when the init method of an applet is called, please read about the lifecycle of an applet at The Life Cycle of an Applet from the Java Tutorials.

var newData = [1,2,3,4,5,6,7];
var chart = $('#chartjs').highcharts();
chart.series[0].setData(newData, true);

Explanation:
Variable newData contains value that want to update in chart. Variable chart is an object of a chart. setData is a method provided by highchart to update data.

Method setData contains two parameters, in first parameter we need to pass new value as array and second param is Boolean value. If true then chart updates itself and if false then we have to use redraw() method to update chart (i.e chart.redraw();)

Let's say you have a shiny Foo class. Well you have 3 options:

1) You want to use the method (or attribute) of a class inside the definition of that class:

class Foo(object):
    attribute1 = 1                   # class attribute (those don't use 'self' in declaration)
    def __init__(self):
        self.attribute2 = 2          # instance attribute (those are accessible via first
                                     # parameter of the method, usually called 'self'
                                     # which will contain nothing but the instance itself)
    def set_attribute3(self, value): 
        self.attribute3 = value

    def sum_1and2(self):
        return self.attribute1 + self.attribute2

2) You want to use the method (or attribute) of a class outside the definition of that class

def get_legendary_attribute1():
    return Foo.attribute1

def get_legendary_attribute2():
    return Foo.attribute2

def get_legendary_attribute1_from(cls):
    return cls.attribute1

get_legendary_attribute1()           # >>> 1
get_legendary_attribute2()           # >>> AttributeError: type object 'Foo' has no attribute 'attribute2'
get_legendary_attribute1_from(Foo)   # >>> 1

3) You want to use the method (or attribute) of an instantiated class:

f = Foo()
f.attribute1                         # >>> 1
f.attribute2                         # >>> 2
f.attribute3                         # >>> AttributeError: 'Foo' object has no attribute 'attribute3'
f.set_attribute3(3)
f.attribute3                         # >>> 3

What format are you wanting the output?

If you're happy with a string then consider the following C# code:

double num = 3.12345;
num.ToString("G3");

The result will be "3.12".

This link might be of use if you're using .NET. http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx

I hope that helps....but unless you identify than language you are using and the format in which you want the output it is difficult to suggest an appropriate solution.

Sort of combined the first two answers, with a tweak to ironfroggy's code so that it returns a tuple:

import operator

class stuple(tuple):
    def __add__(self, other):
        return self.__class__(map(operator.add, self, other))
        # obviously leaving out checking lengths

>>> a = stuple([1,2,3])
>>> b = stuple([3,2,1])
>>> a + b
(4, 4, 4)

Note: using self.__class__ instead of stuple to ease subclassing.

Removing outline will harm accessibility of a website.Therefore i just leave that there but make it invisible.

a {
   outline: transparent;
}

def merge_with(f, xs, ys):
    xs = a_copy_of(xs) # dict(xs), maybe generalizable?
    for (y, v) in ys.iteritems():
        xs[y] = v if y not in xs else f(xs[x], v)

merge_with((lambda x, y: x + y), A, B)

You could easily generalize this:

def merge_dicts(f, *dicts):
    result = {}
    for d in dicts:
        for (k, v) in d.iteritems():
            result[k] = v if k not in result else f(result[k], v)

Then it can take any number of dicts.

delete sub from (select ROW_NUMBER() OVer(Partition by empid order by empid)cnt from employee)sub where sub.cnt>1

background: rgba(0,0,0,.5);

you can use rgba for opacity, will only work in ie9+ and better browsers

To summarize and explain visually how it works. Code construction is as follows:

par(mar = c(3,2,2,1))
barplot(...all parameters...)
title("Title text", adj = 0.5, line = 0)

explanation:

par(mar = c(low, left, top, right)) - margins of the graph area.

title("text" - title text
      adj  = from left (0) to right (1) with anything in between: 0.1, 0.2, etc...
      line = positive values move title text up, negative - down)

What version of .NET and Visual Studio are you using?

When you created the new project, you should have a file in your solution called app.config. That is the default configuration file.

Now we can! As this is the first result on google, I thought I'd update this to the latest standing. With the advent of git 1.7.9.5, we have the git archive command which will allow you to retrieve a single file from a remote host.

git archive --remote=git://git.foo.com/project.git HEAD:path/in/repo filename | tar -x

See answer in full here https://stackoverflow.com/a/5324532/290784

If the purpose of reading environment variable is to override the values in the appsetting.json or any other config file, you can archive it through EnvironmentVariablesExtensions.

var builder = new ConfigurationBuilder()
                .AddJsonFile("appSettings.json")
                .AddEnvironmentVariables(prefix: "ABC_")

var config = builder.Build();

According to this example, Url for the environment is read from the appsettings.json. but when the AddEnvironmentVariables(prefix: "ABC_") line is added to the ConfigurationBuilder the value appsettings.json will be override by in the environement varibale value.

If you want to set required to true

$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',true);
});

if you want to set required to false

$(document).ready(function(){
$('#edit-submitted-first-name').prop('required',false);
});

Let's say you are writing a test case for a negative flow where the code being tested should raise an exception.

try{
   bizMethod(badData);
   fail(); // FAIL when no exception is thrown
} catch (BizException e) {
   assert(e.errorCode == THE_ERROR_CODE_U_R_LOOKING_FOR)
}

If you are in a directory where only root have access to write in system. Then you can directly use wget www.example.com/wget-test using a standard user account. So it will hit the url but because of having no write permission file won't be saved.. This method is working fine for me as i am using this method for a cronjob. Thanks.

sthx

If you have a SSHClient, you can also use open_sftp():

import paramiko


# lets say you have SSH client...
client = paramiko.SSHClient()

sftp = client.open_sftp()

# then you can use upload & download as shown above
...

If you don't want to build custom filter then you can use directly

{{ foo.awesome_property.substring(0,1) | uppercase}}{{foo.awesome_property.substring(1)}}

In my opinion none of the answers so far are ideal. To be ideal I would expect the solution:

1. Support the ==,!=,=,&,&=,|,|= and ~ operators in the conventional sense (i.e. a & b)
2. Be type safe i.e. not permit non-enumerated values such as literals or integer types to be assigned (except for bitwise combinations of enumerated values) or allow an enum variable to be assigned to an integer type
3. Permit expressions such as if (a & b)...
4. Not require evil macros, implementation specific features or other hacks

Most of the solutions thus far fall over on points 2 or 3. WebDancer's is the closes in my opinion but fails at point 3 and needs to be repeated for every enum.

My proposed solution is a generalized version of WebDancer's that also addresses point 3:

#include <cstdint>
#include <type_traits>

template<typename T = typename std::enable_if<std::is_enum<T>::value, T>::type>
class auto_bool
{
    T val_;
public:
    constexpr auto_bool(T val) : val_(val) {}
    constexpr operator T() const { return val_; }
    constexpr explicit operator bool() const
    {
        return static_cast<std::underlying_type_t<T>>(val_) != 0;
    }
};

template <typename T = typename std::enable_if<std::is_enum<T>::value, T>::type>
constexpr auto_bool<T> operator&(T lhs, T rhs)
{
    return static_cast<T>(
        static_cast<typename std::underlying_type<T>::type>(lhs) &
        static_cast<typename std::underlying_type<T>::type>(rhs));
}

template <typename T = typename std::enable_if<std::is_enum<T>::value, T>::type>
constexpr T operator|(T lhs, T rhs)
{
    return static_cast<T>(
        static_cast<typename std::underlying_type<T>::type>(lhs) |
        static_cast<typename std::underlying_type<T>::type>(rhs));
}

enum class AnimalFlags : uint8_t 
{
    HasClaws = 1,
    CanFly = 2,
    EatsFish = 4,
    Endangered = 8
};

enum class PlantFlags : uint8_t
{
    HasLeaves = 1,
    HasFlowers = 2,
    HasFruit = 4,
    HasThorns = 8
};

int main()
{
    AnimalFlags seahawk = AnimalFlags::CanFly;        // Compiles, as expected
    AnimalFlags lion = AnimalFlags::HasClaws;         // Compiles, as expected
    PlantFlags rose = PlantFlags::HasFlowers;         // Compiles, as expected
//  rose = 1;                                         // Won't compile, as expected
    if (seahawk != lion) {}                           // Compiles, as expected
//  if (seahawk == rose) {}                           // Won't compile, as expected
//  seahawk = PlantFlags::HasThorns;                  // Won't compile, as expected
    seahawk = seahawk | AnimalFlags::EatsFish;        // Compiles, as expected
    lion = AnimalFlags::HasClaws |                    // Compiles, as expected
           AnimalFlags::Endangered;
//  int eagle = AnimalFlags::CanFly |                 // Won't compile, as expected
//              AnimalFlags::HasClaws;
//  int has_claws = seahawk & AnimalFlags::CanFly;    // Won't compile, as expected
    if (seahawk & AnimalFlags::CanFly) {}             // Compiles, as expected
    seahawk = seahawk & AnimalFlags::CanFly;          // Compiles, as expected

    return 0;
}

This creates overloads of the necessary operators but uses SFINAE to limit them to enumerated types. Note that in the interests of brevity I haven't defined all of the operators but the only one that is any different is the &. The operators are currently global (i.e. apply to all enumerated types) but this could be reduced either by placing the overloads in a namespace (what I do), or by adding additional SFINAE conditions (perhaps using particular underlying types, or specially created type aliases). The underlying_type_t is a C++14 feature but it seems to be well supported and is easy to emulate for C++11 with a simple template<typename T> using underlying_type_t = underlying_type<T>::type;

Try import tkinter because pycharm already installed tkinter for you, I looked Install tkinter for Python

You can maybe try:

import tkinter
import matplotlib
matplotlib.use('TkAgg')
plt.plot([1,2,3],[5,7,4])
plt.show()

as a tkinter-installing way

I've tried your way, it seems no error to run at my computer, it successfully shows the figure. maybe because pycharm have tkinter as a system package, so u don't need to install it. But if u can't find tkinter inside, you can go to Tkdocs to see the way of installing tkinter, as it mentions, tkinter is a core package for python.

I think you want to test your RegExp in TypeScript, so you have to do like this:

var trigger = "2",
    regexp = new RegExp('^[1-9]\d{0,2}$'),
    test = regexp.test(trigger);
alert(test + ""); // will display true

You should read MDN Reference - RegExp, the RegExp object accepts two parameters pattern and flags which is nullable(can be omitted/undefined). To test your regex you have to use the .test() method, not passing the string you want to test inside the declaration of your RegExp!

Why test + ""? Because alert() in TS accepts a string as argument, it is better to write it this way. You can try the full code here.

add this to your activity

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if ((keyCode == KeyEvent.KEYCODE_BACK))
    {
        finish();
    }
    return super.onKeyDown(keyCode, event);
}

The withColumn function in pyspark enables you to make a new variable with conditions, add in the when and otherwise functions and you have a properly working if then else structure. For all of this you would need to import the sparksql functions, as you will see that the following bit of code will not work without the col() function. In the first bit, we declare a new column -'new column', and then give the condition enclosed in when function (i.e. fruit1==fruit2) then give 1 if the condition is true, if untrue the control goes to the otherwise which then takes care of the second condition (fruit1 or fruit2 is Null) with the isNull() function and if true 3 is returned and if false, the otherwise is checked again giving 0 as the answer.

from pyspark.sql import functions as F
df=df.withColumn('new_column', 
    F.when(F.col('fruit1')==F.col('fruit2'), 1)
    .otherwise(F.when((F.col('fruit1').isNull()) | (F.col('fruit2').isNull()), 3))
    .otherwise(0))

I do this to get the first and last value. This works with more values too.

$a = array(
    'foo' => 400,
    'bar' => 'xyz',
);
$first = current($a);   //400
$last = end($a);    //xyz

Simple solution for angular 5 users is, just add routerLinkActive to the list item.

A routerLinkActive directive is associated with a route through a routerLink directive.

It takes as input an array of classes which it will add to the element it’s attached to if it’s route is currently active, like so:

<li class="nav-item"
    [routerLinkActive]="['active']">
  <a class="nav-link"
     [routerLink]="['home']">Home
  </a>
</li>

The above will add a class of active to the anchor tag if we are currently viewing the home route.

k old post but no one use list expression to answer :P

list =[ ['a','b'], ['a','c'], ['b','d'] ]
Search = 'c'

# return if it find in either item 0 or item 1
print [x for x,y in list if x == Search or y == Search]

# return if it find in item 1
print [x for x,y in list if y == Search]

If you're using Eclipse, then add the reference library into your project as the following steps:

1. Right-click your project in the Project Explorer View.
2. Click Properties.
3. Click Android in the Properties window.
4. In the Library group, click Add...
   • See the image below.
5. Select the library. Click OK.
6. Click the OK button again in the Properties window.

Updated Version (Version 5.0 & Later):

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Post extends Model {

    use SoftDeletes;

    protected $table = 'posts';

    // ...
}

When soft deleting a model, it is not actually removed from your database. Instead, a deleted_at timestamp is set on the record. To enable soft deletes for a model, specify the softDelete property on the model (Documentation).

For (Version 4.2):

use Illuminate\Database\Eloquent\SoftDeletingTrait; // <-- This is required

class Post extends Eloquent {

    use SoftDeletingTrait;

    protected $table = 'posts';

    // ...
}

Prior to Version 4.2 (But not 4.2 & Later)

For example (Using a posts table and Post model):

class Post extends Eloquent {

    protected $table = 'posts';
    protected $softDelete = true;
    
    // ...
}

To add a deleted_at column to your table, you may use the softDeletes method from a migration:

For example (Migration class' up method for posts table) :

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('posts', function(Blueprint $table)
    {
        $table->increments('id');
        // more fields
        $table->softDeletes(); // <-- This will add a deleted_at field
        $table->timeStamps();
    });
}

Now, when you call the delete method on the model, the deleted_at column will be set to the current timestamp. When querying a model that uses soft deletes, the "deleted" models will not be included in query results. To soft delete a model you may use:

$model = Contents::find( $id );
$model->delete();

Deleted (soft) models are identified by the timestamp and if deleted_at field is NULL then it's not deleted and using the restore method actually makes the deleted_at field NULL. To permanently delete a model you may use forceDelete method.

I've found that for bigger arrays (~100k elements), it actually pays to simply iterate the array with a humble for loop, performing ~30% better than Math.max.apply():

function mymax(a)
{
    var m = -Infinity, i = 0, n = a.length;

    for (; i != n; ++i) {
        if (a[i] > m) {
            m = a[i];
        }
    }

    return m;
}

you dont have to do that in the Google chrome. Use the Internet explorer it offers the option to copy the css associated and after you copy and paste select the style and put that into another file .css to call into that html which you have created. Hope this will solve you problem than anything else:)

You can also use logical tests

x <- data.frame(a = c(0,1,2,NA), b = c(0,NA,1,2), c = c(NA, 0, 1, 2)) 
x
x$a <- replace(x$a, is.na(x$a), 0)
x
x$b <- replace(x$b, x$b==2, 333)

If you want to hide the cursor in the entire webpage, using body will not work unless it covers the entire visible page, which is not always the case. To make sure the cursor is hidden everywhere in the page, use:

document.documentElement.style.cursor = 'none';

To reenable it:

document.documentElement.style.cursor = 'auto';

The analogue with static CSS notation is in the answer by Pavel Salaquarda (in essence: html * {cursor:none})

I also had the same problem. net stop http didn't help and World wide web services option under IIS in Windows Control Panel was unchecked. So in XAMPP control panel I just checked the Svc checkbox near Apache start button (Install Apache as service) and rebooted Windows. And now each time Windows starts Apache is started automatically and occupies port 80 before any other service does. Worked for me!
