No, because that would open up the floodgates for phishing. The only part of the URI you can change is the fragment (everything after the #). You can do so by setting window.location.hash.

You can do it without setlocal, because of the setlocal command the variable won't survive an endlocal because it was created in setlocal. In this way the variable will be defined the right way.

To do that use this code:

set var1=A

set var2=B

set AB=hi

call set newvar=%%%var1%%var2%%%

echo %newvar% 

Note: You MUST use call before you set the variable or it won't work.

With [ChildActionOnly] attribute annotated, an action method can be called only as a child method from within a view. Here is an example for [ChildActionOnly]..

there are two action methods: Index() and MyDateTime() and corresponding Views: Index.cshtml and MyDateTime.cshtml. this is HomeController.cs

public class HomeController : Controller
 {
    public ActionResult Index()
    {
        ViewBag.Message = "This is from Index()";
        var model = DateTime.Now;
        return View(model);
    }

    [ChildActionOnly]
    public PartialViewResult MyDateTime()
    {
        ViewBag.Message = "This is from MyDateTime()";

        var model = DateTime.Now;
        return PartialView(model);
    } 
}

Here is the view for Index.cshtml.

@model DateTime
@{
    ViewBag.Title = "Index";
}
<h2>
    Index</h2>
<div>
    This is the index view for Home : @Model.ToLongTimeString()
</div>
<div>
    @Html.Action("MyDateTime")  // Calling the partial view: MyDateTime().
</div>

<div>
    @ViewBag.Message
</div>

Here is MyDateTime.cshtml partial view.

@model DateTime

<p>
This is the child action result: @Model.ToLongTimeString()
<br />
@ViewBag.Message
</p>

 if you run the application and do this request http://localhost:57803/home/mydatetime
 The result will be Server Error like so: 

This means you can not directly call the partial view. but it can be called via Index() view as in the Index.cshtml

     @Html.Action("MyDateTime")  // Calling the partial view: MyDateTime().
 

If you remove [ChildActionOnly] and do the same request http://localhost:57803/home/mydatetime it allows you to get the mydatetime partial view result:

This is the child action result. 12:53:31 PM 
This is from MyDateTime()

Either make ActiveAlarm implement Comparable<ActiveAlarm> or implement Comparator<ActiveAlarm> in a separate class. Then call:

Collections.sort(list);

or

Collections.sort(list, comparator);

In general, it's a good idea to implement Comparable<T> if there's a single "natural" sort order... otherwise (if you happen to want to sort in a particular order, but might equally easily want a different one) it's better to implement Comparator<T>. This particular situation could go either way, to be honest... but I'd probably stick with the more flexible Comparator<T> option.

EDIT: Sample implementation:

public class AlarmByTimesComparer implements Comparator<ActiveAlarm> {
  @Override
  public int compare(ActiveAlarm x, ActiveAlarm y) {
    // TODO: Handle null x or y values
    int startComparison = compare(x.timeStarted, y.timeStarted);
    return startComparison != 0 ? startComparison
                                : compare(x.timeEnded, y.timeEnded);
  }

  // I don't know why this isn't in Long...
  private static int compare(long a, long b) {
    return a < b ? -1
         : a > b ? 1
         : 0;
  }
}

Try this for multiple text fileds (using class selector):

Click here for example..

var checking = function(event){_x000D_
 var data = this.value;_x000D_
 if((event.charCode>= 48 && event.charCode <= 57) || event.charCode== 46 ||event.charCode == 0){_x000D_
  if(data.indexOf('.') > -1){_x000D_
    if(event.charCode== 46)_x000D_
      event.preventDefault();_x000D_
  }_x000D_
 }else_x000D_
  event.preventDefault();_x000D_
 };_x000D_
_x000D_
 function addListener(list){_x000D_
  for(var i=0;i<list.length;i++){_x000D_
      list[i].addEventListener('keypress',checking);_x000D_
     }_x000D_
 }_x000D_
 var classList = document.getElementsByClassName('number');_x000D_
 addListener(classList);

<!DOCTYPE html>_x000D_
<html>_x000D_
<head>_x000D_
<title>Page Title</title>_x000D_
</head>_x000D_
<body>_x000D_
  <input type="text" class="number" value="" /><br><br>_x000D_
  <input type="text" class="number" value="" /><br><br>_x000D_
  <input type="text" class="number" value="" /><br><br>_x000D_
  <input type="text" class="number" value="" /><br><br>_x000D_
</body>_x000D_
</html>

For people that need the title set statically. This can be done in the AndroidManifest.xml

<activity
    android:name=".ActivityName"
    android:label="Title Text" >
</activity>

There are more than a couple of mistakes in the code.

1. 'import sys' line should be outside the functions as the function is itself being called using arguments fetched using sys functions.
2. If you want correct sum, you should cast the arguments (strings) into floats. Change the sum line to --> sum = float(a) + float(b).

3. Since you have not defined any default values for any of the function arguments, it is necessary to pass both arguments while calling the function --> hello(sys.argv[2], sys.argv[2])

   import sys def hello(a,b): print ("hello and that's your sum:") sum=float(a)+float(b) print (sum)

   if __name__ == "__main__": hello(sys.argv[1], sys.argv[2])

Also, using "C:\Python27>hello 1 1" to run the code looks fine but you have to make sure that the file is in one of the directories that Python knows about (PATH env variable). So, please use the full path to validate the code. Something like:

C:\Python34>python C:\Users\pranayk\Desktop\hello.py 1 1

I was facing the same issue; and the following worked well for me. Hope this helps someone landing here:

<div class="row">
  <div class="col-md-6">
     <div class="col-md-12">
        Some Content.. 
     </div>
  </div>
  <div class="col-md-6">
     <div class="col-md-12">
        Some Second Content.. 
     </div>
  </div>
</div>

This will automatically render some space between the 2 divs.

I went overkill and came up with the following. My motivation behind this was to append to hash keys to avoid scope conflicts when merging together/flattening hashes.

Examples

Extend Hash Class

Adds rekey method to Hash instances.

# Adds additional methods to Hash
class ::Hash
  # Changes the keys on a hash
  # Takes a block that passes the current key
  # Whatever the block returns becomes the new key
  # If a hash is returned for the key it will merge the current hash 
  # with the returned hash from the block. This allows for nested rekeying.
  def rekey
    self.each_with_object({}) do |(key, value), previous|
      new_key = yield(key, value)
      if new_key.is_a?(Hash)
        previous.merge!(new_key)
      else
        previous[new_key] = value
      end
    end
  end
end

Prepend Example

my_feelings_about_icecreams = {
  vanilla: 'Delicious',
  chocolate: 'Too Chocolatey',
  strawberry: 'It Is Alright...'
}

my_feelings_about_icecreams.rekey { |key| "#{key}_icecream".to_sym }
# => {:vanilla_icecream=>"Delicious", :chocolate_icecream=>"Too Chocolatey", :strawberry_icecream=>"It Is Alright..."}

Trim Example

{ _id: 1, ___something_: 'what?!' }.rekey do |key|
  trimmed = key.to_s.tr('_', '')
  trimmed.to_sym
end
# => {:id=>1, :something=>"what?!"}

Flattening and Appending a "Scope"

If you pass a hash back to rekey it will merge the hash which allows you to flatten collections. This allows us to add scope to our keys when flattening a hash to avoid overwriting a key upon merging.

people = {
  bob: {
    name: 'Bob',
    toys: [
      { what: 'car', color: 'red' },
      { what: 'ball', color: 'blue' }
    ]
  },
  tom: {
    name: 'Tom',
    toys: [
      { what: 'house', color: 'blue; da ba dee da ba die' },
      { what: 'nerf gun', color: 'metallic' }
    ]
  }
}

people.rekey do |person, person_info|
  person_info.rekey do |key|
    "#{person}_#{key}".to_sym
  end
end

# =>
# {
#   :bob_name=>"Bob",
#   :bob_toys=>[
#     {:what=>"car", :color=>"red"},
#     {:what=>"ball", :color=>"blue"}
#   ],
#   :tom_name=>"Tom",
#   :tom_toys=>[
#     {:what=>"house", :color=>"blue; da ba dee da ba die"},
#     {:what=>"nerf gun", :color=>"metallic"}
#   ]
# }

geonames.org has an api and a data dump of worldwide geographical places.

As mentioned by theoobe, some browsers do not close the websockets automatically. Don't try to handle any "close browser window" events client-side. There is currently no reliable way to do it, if you consider support of major desktop AND mobile browsers (e.g. onbeforeunload will not work in Mobile Safari). I had good experience with handling this problem server-side. E.g. if you use Java EE, take a look at javax.websocket.Endpoint, depending on the browser either the OnClose method or the OnError method will be called if you close/reload the browser window.

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

I think @Dmitri has nice solution at Matching strings with wildcard https://stackoverflow.com/a/30300521/1726296

Based on his solution, I have created two extension methods. (credit goes to him)

May be helpful.

public static String WildCardToRegular(this String value)
{
        return "^" + Regex.Escape(value).Replace("\\?", ".").Replace("\\*", ".*") + "$";
}

public static bool WildCardMatch(this String value,string pattern,bool ignoreCase = true)
{
        if (ignoreCase)
            return Regex.IsMatch(value, WildCardToRegular(pattern), RegexOptions.IgnoreCase);

        return Regex.IsMatch(value, WildCardToRegular(pattern));
}

Usage:

string pattern = "file.*";

var isMatched = "file.doc".WildCardMatch(pattern)

or

string xlsxFile = "file.xlsx"
var isMatched = xlsxFile.WildCardMatch(pattern)

In a directed graph having N vertices, each vertex can connect to N-1 other vertices in the graph(Assuming, no self loop). Hence, the total number of edges can be are N(N-1).

@alessioalex answer is a perfect demo for fresh node user. But anyway, it's hard to write checkAuth middleware into all routes except login, so it's better to move the checkAuth from every route to one entry with app.use. For example:

function checkAuth(req, res, next) {
  // if logined or it's login request, then go next route
  if (isLogin || (req.path === '/login' && req.method === 'POST')) {
    next()
  } else {
    res.send('Not logged in yet.')
  }
}

app.use('/', checkAuth)

Often enterprise databases have several users and I'm not aways on the right one :

SELECT * FROM ALL_CONSTRAINTS WHERE table_name = 'YOUR TABLE NAME' ;

Picked from Oracle documentation

From the documentation page

To set the page type pass the value in constructor

jsPDF(orientation, unit, format) Creates new jsPDF document object

instance Parameters:

orientation One of "portrait" or "landscape" (or shortcuts "p" (Default), "l")

unit Measurement unit to be used when coordinates are specified. One of "pt" (points), "mm" (Default), "cm", "in"

format One of 'a3', 'a4' (Default),'a5' ,'letter' ,'legal'

To set font size

setFontSize(size)

Sets font size for upcoming text elements.

Parameters:

{Number} size Font size in points.

Since JQuery 1.6, always use .prop() Read why here: http://api.jquery.com/prop/

if($('input').prop('readonly')){ }

.prop() can also be used to set the property

$('input').prop('readonly',true);

$('input').prop('readonly',false);

As others have noted, you need to declare a variable global in a function when you want that function to be able to modify the global variable. If you only want to access it, then you don't need global.

To go into a bit more detail on that, what "modify" means is this: if you want to re-bind the global name so it points to a different object, the name must be declared global in the function.

Many operations that modify (mutate) an object do not re-bind the global name to point to a different object, and so they are all valid without declaring the name global in the function.

d = {}
l = []
o = type("object", (object,), {})()

def valid():     # these are all valid without declaring any names global!
   d[0] = 1      # changes what's in d, but d still points to the same object
   d[0] += 1     # ditto
   d.clear()     # ditto! d is now empty but it`s still the same object!
   l.append(0)   # l is still the same list but has an additional member
   o.test = 1    # creating new attribute on o, but o is still the same object

Here's how I would make the next ID:

INSERT INTO table_name (
            ID,
            FIRSTNAME,
            SURNAME) 
            VALUES ((( 
                    SELECT COALESCE(MAX(B.ID)+1,1) AS NEXTID 
                        FROM table_name B
                        )), John2, Smith2);

With this you can make sure that even if the table ID is NULL, it will still work perfectly.

Your collection class could have a method that returns a collection (a sublist) based on criteria passed in to define the filter. Build a new collection with the foreach loop and pass it out.

Or, have the method and loop modify the existing collection by setting a "filtered" or "active" flag (property). This one could work but could also cause poblems in multithreaded code. If other objects deped on the contents of the collection this is either good or bad depending of how you use the data.

Try this:

string m = Enum.GetName(typeof(MyEnumClass), value);

DateTimeUtils obj = new DateTimeUtils();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/M/yyyy hh:mm:ss");

try {
    Date date1 = simpleDateFormat.parse("10/10/2013 11:30:10");
    Date date2 = simpleDateFormat.parse("13/10/2013 20:35:55");

    obj.printDifference(date1, date2);

} catch (ParseException e) {
    e.printStackTrace();
}

//1 minute = 60 seconds
//1 hour = 60 x 60 = 3600
//1 day = 3600 x 24 = 86400
public void printDifference(Date startDate, Date endDate) { 
    //milliseconds
    long different = endDate.getTime() - startDate.getTime();

    System.out.println("startDate : " + startDate);
    System.out.println("endDate : "+ endDate);
    System.out.println("different : " + different);

    long secondsInMilli = 1000;
    long minutesInMilli = secondsInMilli * 60;
    long hoursInMilli = minutesInMilli * 60;
    long daysInMilli = hoursInMilli * 24;

    long elapsedDays = different / daysInMilli;
    different = different % daysInMilli;

    long elapsedHours = different / hoursInMilli;
    different = different % hoursInMilli;

    long elapsedMinutes = different / minutesInMilli;
    different = different % minutesInMilli;

    long elapsedSeconds = different / secondsInMilli;

    System.out.printf(
        "%d days, %d hours, %d minutes, %d seconds%n", 
        elapsedDays, elapsedHours, elapsedMinutes, elapsedSeconds);
}

out put is :

startDate : Thu Oct 10 11:30:10 SGT 2013
endDate : Sun Oct 13 20:35:55 SGT 2013
different : 291945000
3 days, 9 hours, 5 minutes, 45 seconds

Also you can use ss utility to dump sockets statistics.

To dump summary:

ss -s

Total: 91 (kernel 0)
TCP:   18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0

Transport Total     IP        IPv6
*         0         -         -        
RAW       0         0         0        
UDP       4         2         2        
TCP       18        16        2        
INET      22        18        4        
FRAG      0         0         0

To display all sockets:

ss -a

To display UDP sockets:

ss -u -a

To display TCP sockets:

ss -t -a

Here you can read ss man: ss

in MySQL schema is synonym of database. Its quite confusing for beginner people who jump to MySQL and very first day find the word schema, so guys nothing to worry as both are same.

When you are starting MySQL for the first time you need to create a database (like any other database system) to work with so you can CREATE SCHEMA which is nothing but CREATE DATABASE

In some other database system schema represents a part of database or a collection of Tables, and collection of schema is a database.

I had a similar scenario, and I thought that something like

str.replaceAll("\[|\]", "");

looked cleaner. Of course, if your token might have brackets in it, that wouldn't work.

I looked at the designer code from one of my projects and noticed it used this notation

myButton.Image = global::MyProjectName.Properties.Resources.max;

where max is the name of the resource I uploaded into the project.

Note: I now this is not the answer for the post, but maybe this will be helpful for some one that is looking.

If Nothing of this works for you, try on a Mac this to see if helps you, in the last version of Android Studio, the studio.vmoptions is inside the AndroidStudio.app in your Applications folder.

So right click or ctrl click on your AndroidStudio.App and then select show package content the studio.vmoptions is in:

Contents/bin/studio.vmoptions

Replace or change it and you will get all the RAM you need.

sudo apt-get install libsecret-1-0 libsecret-1-dev
cd /usr/share/doc/git/contrib/credential/libsecret
sudo make
git config --global credential.helper /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret

Some other distro's provide the binary so you don't have to build it.

In OS X it typically comes "built" with a default module of "osxkeychain" so you get it for free.

You just need to iterate the anchors in the two links.

<a href="#hide2" class="hide" id="hide2">+</a>
<a href="#show2" class="show" id="show2">-</a>

See this jsfiddle http://jsfiddle.net/eJX8z/

I also added some margin to the FAQ call to improve the format.

If you use Eclipse Collections you can use the collectIf() method.

MutableList<Integer> source =
    Lists.mutable.with(1, null, 2, null, 3, null, 4, null, 5);

MutableList<String> result = source.collectIf(Objects::nonNull, String::valueOf);

Assert.assertEquals(Lists.immutable.with("1", "2", "3", "4", "5"), result);

It evaluates eagerly and should be a bit faster than using a Stream.

Note: I am a committer for Eclipse Collections.

Calling exactly super() is always redundant. It's explicitly doing what would be implicitly done otherwise. That's because if you omit a call to the super constructor, the no-argument super constructor will be invoked automatically anyway. Not to say that it's bad style; some people like being explicit.

However, where it becomes useful is when the super constructor takes arguments that you want to pass in from the subclass.

public class Animal {
   private final String noise;
   protected Animal(String noise) {
      this.noise = noise;
   }

   public void makeNoise() {
      System.out.println(noise);
   }
}

public class Pig extends Animal {
    public Pig() {
       super("Oink");
    }
}

A simple solution with jQuery:

$('body').find(yourElement)[0] != null

After creating your client specifying the binding and endpoint address, you can assign an OperationTimeout,

client.InnerChannel.OperationTimeout = new TimeSpan(0, 5, 0);

If you set <TextView> in center in <Linearlayout> then first put android:layout_width="fill_parent" compulsory
No need of using any other gravity

    <LinearLayout
            android:layout_toRightOf="@+id/linear_profile" 
            android:layout_height="wrap_content"
            android:layout_width="fill_parent"
            android:orientation="vertical"
            android:gravity="center_horizontal">
            <TextView 
                android:layout_height="wrap_content"
                android:layout_width="wrap_content"
                android:text="It's.hhhhhhhh...."
                android:textColor="@color/Black"

                />
    </LinearLayout>

Eloquent uses the query builder internally, so you can do:

$users = User::orderBy('name', 'desc')
                ->groupBy('count')
                ->having('count', '>', 100)
                ->get();

if you want to set value than you can do the same in some function on click or on some event fire.

also you can get value using ViewChild using local variable like this

<input type='text' id='loginInput' #abc/>

and get value like this

this.abc.nativeElement.value

here is working example

Update

okay got it , you have to use ngAfterViewInit method of angualr2 for the same like this

ngAfterViewInit(){
    document.getElementById('loginInput').value = '123344565';
  }

ngAfterViewInit will not throw any error because it will render after template loading

I found another option so you can just use @Html.EditorFor() with templates:

Say I have this enum:

public enum EmailType { Pdf, Html }

I can put this code in Views/Shared/EditorTemplates/EmailType.cshtml

@model EmailType
@{
    var htmlOptions = Model == EmailType.Html ? new { @checked = "checked" } : null;
    var pdfOptions = Model == EmailType.Pdf ? new { @checked = "checked" } : null;
}

@Html.RadioButtonFor(x => x, EmailType.Html, htmlOptions) @EmailType.Html.ToString()
@Html.RadioButtonFor(x => x, EmailType.Pdf, pdfOptions) @EmailType.Pdf.ToString()

Now I can simply use this if I want to use it at any time:

@Html.EditorFor(x => x.EmailType)

It's much more universal this way, and easier to change I feel.

The cool thing about the new Google Recaptcha is that the validation is now completely encapsulated in the widget. That means, that the widget will take care of asking questions, validating responses all the way till it determines that a user is actually a human, only then you get a g-recaptcha-response value.

But that does not keep your site safe from HTTP client request forgery.

Anyone with HTTP POST knowledge could put random data inside of the g-recaptcha-response form field, and foll your site to make it think that this field was provided by the google widget. So you have to validate this token.

In human speech it would be like,

• Your Server: Hey Google, there's a dude that tells me that he's not a robot. He says that you already verified that he's a human, and he told me to give you this token as a proof of that.
• Google: Hmm... let me check this token... yes I remember this dude I gave him this token... yeah he's made of flesh and bone let him through.
• Your Server: Hey Google, there's another dude that tells me that he's a human. He also gave me a token.
• Google: Hmm... it's the same token you gave me last time... I'm pretty sure this guy is trying to fool you. Tell him to get off your site.

Validating the response is really easy. Just make a GET Request to

https://www.google.com/recaptcha/api/siteverify?secret=your_secret&response=response_string&remoteip=user_ip_address

And replace the response_string with the value that you earlier got by the g-recaptcha-response field.

You will get a JSON Response with a success field.

More information here: https://developers.google.com/recaptcha/docs/verify

Edit: It's actually a POST, as per documentation here.

For me it worked to add the phrase "explicit_defaults_for_timestamp = ON" without quotes into the config file my.ini.

Make sure you add this phrase right underneath the [mysqld] statement in the config file.

You will find my.ini under C:\ProgramData\MySQL\MySQL Server 5.7 if you had conducted the default installation of MySQL.

Create a separate ul.nav for just that list item and float that ul right.

var content = document.getElementById("one").innerText;
alert(content);

if you looking for a way how to download temporary file, do stuff and delete it try this gem https://github.com/equivalent/pull_tempfile

require 'pull_tempfile'

PullTempfile.transaction(url: 'https://mycompany.org/stupid-csv-report.csv', original_filename: 'dont-care.csv') do |tmp_file|
  CSV.foreach(tmp_file.path) do |row|

Hows about this:

$json=Get-Content -Raw -Path 'my.json' | Out-String | ConvertFrom-Json
$foo="TheVariableYourUsingToSelectSomething"
$json.SomePathYouKnow.psobject.properties.Where({$_.name -eq $foo}).value

which would select from json structured

{"SomePathYouKnow":{"TheVariableYourUsingToSelectSomething": "Tada!"}

This is based on this accessing values in powershell SO question . Isn't powershell fabulous!

I like List comprehensions because of their Math (Set) syntax. So how about this:

L = [1, 2, 3, 4, 5, 6, 7]
odd_numbers = [y for x,y in enumerate(L) if x%2 != 0]
even_numbers = [y for x,y in enumerate(L) if x%2 == 0]

Basically, if you enumerate over a list, you'll get the index x and the value y. What I'm doing here is putting the value y into the output list (even or odd) and using the index x to find out if that point is odd (x%2 != 0).

My answer is "neither one".

I believe the most "Pythonic" way to do things is to NOT check beforehand if the key is in a dictionary and instead just write code that assumes it's there and catch any KeyErrors that get raised because it wasn't.

This is usually done with enclosing the code in a try...except clause and is a well-known idiom usually expressed as "It's easier to ask forgiveness than permission" or with the acronym EAFP, which basically means it is better to try something and catch the errors instead for making sure everything's OK before doing anything. Why validate what doesn't need to be validated when you can handle exceptions gracefully instead of trying to avoid them? Because it's often more readable and the code tends to be faster if the probability is low that the key won't be there (or whatever preconditions there may be).

Of course, this isn't appropriate in all situations and not everyone agrees with the philosophy, so you'll need to decide for yourself on a case-by-case basis. Not surprisingly the opposite of this is called LBYL for "Look Before You Leap".

As a trivial example consider:

if 'name' in dct:
    value = dct['name'] * 3
else:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

vs

try:
    value = dct['name'] * 3
except KeyError:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

Although in the case it's almost exactly the same amount of code, the second doesn't spend time checking first and is probably slightly faster because of it (try...except block isn't totally free though, so it probably doesn't make that much difference here).

Generally speaking, testing in advance can often be much more involved and the savings gain from not doing it can be significant. That said, if 'name' in dict: is better for the reasons stated in the other answers.

If you're interested in the topic, this message titled "EAFP vs LBYL (was Re: A little disappointed so far)" from the Python mailing list archive probably explains the difference between the two approached better than I have here. There's also a good discussion about the two approaches in the book Python in a Nutshell, 2nd Ed by Alex Martelli in chapter 6 on Exceptions titled Error-Checking Strategies. (I see there's now a newer 3rd edition, publish in 2017, which covers both Python 2.7 and 3.x).

I'd like to share the trick that helped in my case. I uninstalled the application from the device and nothing of clean/rebuild/Android Studio restart operations didn't help.

Since Android Studio thinks that the application is still installed on the device and doesn't deploy it, you can force the installation using the ADB:

adb install -r <your_application_from.apk>

where -r means reinstall the app, keeping its data.

Try this code:

<?php
$path = '/var/www/html/project/somefolder';

$dirs = array();

// directory handle
$dir = dir($path);

while (false !== ($entry = $dir->read())) {
    if ($entry != '.' && $entry != '..') {
       if (is_dir($path . '/' .$entry)) {
            $dirs[] = $entry; 
       }
    }
}

echo "<pre>"; print_r($dirs); exit;

It's been a while since I read it (so, I'm not sure how much of it is still relevant), but my recollection is that Joe Celko's SQL for Smarties book provides a lot of info on writing elegant, effective, and efficient queries.

Shawn Wildermuth has a nice guide here: https://wildermuth.com/2017/11/19/ASP-NET-Core-2-0-and-the-End-of-Bower

The article links to the gulpfile on GitHub where he's implemented the strategy in the article. You could just copy and paste most of the gulpfile contents into yours, but be sure to add the appropriate packages in package.json under devDependencies: gulp gulp-uglify gulp-concat rimraf merge-stream

If you uninstall all the files but it still fails, use this line:

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk

I see that my response would be quite outdated, but never the less. I faced with the same problem. So here's my solution. The most useful code snipped was KGA's one. But it isn't totally working and is a bit complicated. But I simplified it.

Also, the main trouble maker was that fact, that 'change' event doesn't come instantly after focus, so we have to wait for some time.

"#appendfile" - which user clicks on to append a new file. Hrefs get focus events.

$("#appendfile").one("focusin", function () {
    // no matter - user uploaded file or canceled,
    // appendfile gets focus
    // change doesn't come instantly after focus, so we have to wait for some time
    // wrapper represents an element where a new file input is placed into
    setTimeout(function(){
        if (wrapper.find("input.fileinput").val() != "") {
            // user has uploaded some file
            // add your logic for new file here
        }
        else {
            // user canceled file upload
            // you have to remove a fileinput element from DOM
        }
    }, 900);
});

I don't know why you should think it is dirty... because of the exception? if you want a oneliner, here it is:

thing_index = thing_list.index(elem) if thing_list.count(elem) else -1

but i would advise against using it; I think Ross Rogers solution is the best, use an object to encapsulate your desiderd behaviour, don't try pushing the language to its limits at the cost of readability.

Dispatcher.ShutdownStarted event is fired only at the end of application. It's worth to call the disposing logic just when control gets out of use. In particular it frees resources when control is used many times during application runtime. So ioWint's solution is preferable. Here's the code:

public MyWpfControl()
{
     InitializeComponent();
     Loaded += (s, e) => { // only at this point the control is ready
         Window.GetWindow(this) // get the parent window
               .Closing += (s1, e1) => Somewhere(); //disposing logic here
     };
}

I installed Android Studio on an old WinXP with only for me option. After install I did the new project wizard and when opening the new project a got some Gradle error with some failed path to my instalation dir. c:/Document"#¤!"#¤ and settins/...

The I uninstalled and did a new install with option for all users (C:/Programs/..) then I opend the previous created project with no errors.

So it might be a path problem. (Just spent 10 sec debugging, so I might be wrong but it solved my gradle error)

@Skelly 's answer is correct. It won't let me add a comment (<50 rep)... but to answer your question on his answer: In the example he linked, if you add

col-xs-3 

class to each of the thumbnails, like this:

class="col-md-3 col-xs-3"

then it should stay the way you want it when sized down to phone width.

Solution(s) for this, found in the official wampserver.com forums:

SOLUTION #1:

This problem is caused by Windows (7) in combination with any software that also uses port 80 (like Skype or IIS (which is installed on most developer machines)). A video solution can be found here (34.500+ views, damn, this seems to be a big thing ! EDIT: The video now has ~60.000 views ;) )

To make it short: open command line tool, type "netstat -aon" and look for any lines that end of ":80". Note thatPID on the right side. This is the process id of the software which currently usesport 80. Press AltGr + Ctrl + Del to get into the Taskmanager. Switch to the tab where you can see all services currently running, ordered by PID. Search for that PID you just notices and stop that thing (right click). To prevent this in future, you should config the software's port settings (skype can do that).

SOLUTION #2:

left click the wamp icon in the taskbar, go to apache > httpd.conf and edit this file: change "listen to port .... 80" to 8080. Restart. Done !

SOLUTION #3:

Port 80 blocked by "Microsoft Web Deployment Service", simply deinstall this, more info here

By the way, it's not Microsoft's fault, it's a stupid usage of ports by most WAMP stacks.

IMPORTANT: you have to use localhost or 127.0.0.1 now with port 8080, this means 127.0.0.1:8080 or localhost:8080.

For the replacement string and the replacement pattern as specified by $. here a resume:

link to doc : here

"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")

Note:

If you want to have a $ in the replacement string use $$. Same as with vscode snippet system.

If you want to do this in a robust way that works for every possible command line argument (values with spaces, values with newlines, values with literal quote characters, non-printable values, values with glob characters, etc), it gets a bit more interesting.

To write to a file, given an array of arguments:

printf '%s\0' "${arguments[@]}" >file

...replace with "argument one", "argument two", etc. as appropriate.

To read from that file and use its contents (in bash, ksh93, or another recent shell with arrays):

declare -a args=()
while IFS='' read -r -d '' item; do
  args+=( "$item" )
done <file
run_your_command "${args[@]}"

To read from that file and use its contents (in a shell without arrays; note that this will overwrite your local command-line argument list, and is thus best done inside of a function, such that you're overwriting the function's arguments and not the global list):

set --
while IFS='' read -r -d '' item; do
  set -- "$@" "$item"
done <file
run_your_command "$@"

Note that -d (allowing a different end-of-line delimiter to be used) is a non-POSIX extension, and a shell without arrays may also not support it. Should that be the case, you may need to use a non-shell language to transform the NUL-delimited content into an eval-safe form:

quoted_list() {
  ## Works with either Python 2.x or 3.x
  python -c '
import sys, pipes, shlex
quote = pipes.quote if hasattr(pipes, "quote") else shlex.quote
print(" ".join([quote(s) for s in sys.stdin.read().split("\0")][:-1]))
  '
}

eval "set -- $(quoted_list <file)"
run_your_command "$@"

Here is a more reliable version:

class D(object):
    def __init__(self):
        self.test = 20
        self.test2 = 21
    def __getattribute__(self, name):
        if name == 'test':
            return 0.
        else:
            return super(D, self).__getattribute__(name)

It calls __getattribute__ method from parent class, eventually falling back to object.__getattribute__ method if other ancestors don't override it.

str.append(10u,'d'); //appends character d 10 times

Notice I have written 10u and not 10 for the number of times I'd like to append the character; replace 10 with whatever number.

Check: key = undef !!!

You got also the warn message:

Each child in a list should have a unique "key" prop.

if your code is complete right, but if on

<MyComponent key={someValue} />

someValue is undefined!!! Please check this first. You can save hours.

Right now with using Spring-Boot 2.0.4 - { } won't work.

@RequestMapping

still has String[] as a value parameter, so declaration looks like this:

 @RequestMapping(value=["/","/index","/login","/home"], method = RequestMethod.GET)

** Update - Works With Spring-Boot 2.2**

 @RequestMapping(value={"/","/index","/login","/home"}, method = RequestMethod.GET)

I have created a snippet - inspired by the actual View source - that reliably detects long clicks/presses with a custom delay. But it's in Kotlin:

val LONG_PRESS_DELAY = 500

val handler = Handler()
var boundaries: Rect? = null

var onTap = Runnable {
    handler.postDelayed(onLongPress, LONG_PRESS_DELAY - ViewConfiguration.getTapTimeout().toLong())
}

var onLongPress = Runnable {

    // Long Press
}

override fun onTouch(view: View, event: MotionEvent): Boolean {
    when (event.action) {
        MotionEvent.ACTION_DOWN -> {
            boundaries = Rect(view.left, view.top, view.right, view.bottom)
            handler.postDelayed(onTap, ViewConfiguration.getTapTimeout().toLong())
        }
        MotionEvent.ACTION_UP, MotionEvent.ACTION_CANCEL -> {
            handler.removeCallbacks(onLongPress)
            handler.removeCallbacks(onTap)
        }

            if (!boundaries!!.contains(view.left + event.x.toInt(), view.top + event.y.toInt())) {

                handler.removeCallbacks(onTap)

For some programmer humor, a one liner as a joke:

public static string GetDescription(this Enum value) => value.GetType().GetMember(value.ToString()).First().GetCustomAttribute<DescriptionAttribute>() is DescriptionAttribute attribute ? attribute.Description : string.Empty;

In a more readable form:

using System;
using System.ComponentModel;
using System.Linq;
using System.Reflection;

public static class EnumExtensions
{
    // get description from enum:

    public static string GetDescription(this Enum value)
    {
        return value.GetType().
            GetMember(value.ToString()).
            First().
            GetCustomAttribute<DescriptionAttribute>() is DescriptionAttribute attribute
            ? attribute.Description
            : throw new Exception($"Enum member '{value.GetType()}.{value}' doesn't have a [DescriptionAttribute]!");
    }

    // get enum from description:

    public static T GetEnum<T>(this string description) where T : Enum
    {
        foreach (FieldInfo fieldInfo in typeof(T).GetFields())
        {
            if (fieldInfo.GetCustomAttribute<DescriptionAttribute>() is DescriptionAttribute attribute && attribute.Description == description)
                return (T)fieldInfo.GetRawConstantValue();
        }

        throw new Exception($"Enum '{typeof(T)}' doesn't have a member with a [DescriptionAttribute('{description}')]!");
    }
}

I had the same issue but I solved it by correcting my form open as shown below :

{!!Form::open(['url'=>route('auth.login-post'),'class'=>'form-horizontal'])!!}

If this doesn't solve your problem, can you please show how you opened the form ?

I have a solution below and its works for me:

app.controller('LoginController', ['$http', '$scope', function ($scope, $http) {
$scope.login = function (credentials) {
$http({
        method: 'jsonp',
        url: 'http://mywebservice',
        params: {
            format: 'jsonp',
            callback: 'JSON_CALLBACK'
        }
    }).then(function (response) {
        alert(response.data);
    });
  }
}]);

in 'http://mywebservice' there must be need a callback parameter which return JSON_CALLBACK with data.
There is a sample example below which works perfect

$scope.url = "https://angularjs.org/greet.php";
    $http({
        method: 'jsonp',
        url: $scope.url,
        params: {
            format: 'jsonp',
            name: 'Super Hero',
            callback: 'JSON_CALLBACK'
        }
    }).then(function (response) {
        alert(response.data);
    });

example output:

{"name":"Super Hero","salutation":"Apa khabar","greeting":"Apa khabar Super Hero!"}

let is used to define constants and var to define variables. You define the string using var then particular String can be modified (or mutated) by assigning it to a variable (in which case it can be modified), and if you define the string using let its a constant (in which case it cannot be modified):

var variableString = "Apple"
variableString += " and Banana"
// variableString is now "Apple and Banana"

let constantString = "Apple"
constantString += " and another Banana"
// this reports a compile-time error - a constant string cannot be modified

There is no space allocated for the strings. use array (or) pointers with malloc() and free()

Other than that

#import <stdio.h>
#import <string.h>

should be

#include <stdio.h>
#include <string.h>

NOTE:

• anything that is malloc()ed must be free()'ed
• you need to allocate n + 1 bytes for a string which is of length n (the last byte is for \0)

Please you the following code as a reference

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

int main(int argc, char *argv[])
{
    //char *str1 = "First string";
    char *str1 = "First string is a big string";
    char *str2 = NULL;

    if ((str2 = (char *) malloc(sizeof(char) * strlen(str1) + 1)) == NULL) {
        printf("unable to allocate memory \n");
        return -1; 
    }   

    strcpy(str2, str1);

    printf("str1 : %s \n", str1);
    printf("str2 : %s \n", str2);

    free(str2);
    return 0;
}

If you don't use parallel() this will work

List<Long> sourceLongList = Arrays.asList(1L, 10L, 50L, 80L, 100L, 120L, 133L, 333L);

List<Long> targetLongList =  new ArrayList<Long>();

sourceLongList.stream().peek(i->targetLongList.add(i)).collect(Collectors.toList());

It can be done in pure bash with bash-3.2 as well:

# First, get the first character.
fl=${foo:0:1}

# Safety check: it must be a letter :).
if [[ ${fl} == [a-z] ]]; then
    # Now, obtain its octal value using printf (builtin).
    ord=$(printf '%o' "'${fl}")

    # Fun fact: [a-z] maps onto 0141..0172. [A-Z] is 0101..0132.
    # We can use decimal '- 40' to get the expected result!
    ord=$(( ord - 40 ))

    # Finally, map the new value back to a character.
    fl=$(printf '%b' '\'${ord})
fi

echo "${fl}${foo:1}"

I had the same problem.

1. Click the right button in your site folder in "iis"
2. "Convert to Application".

As Internet Explorer doesn't natively support rounded corners. So a better cross-browser way to handle it would be to use rounded-corner images at the corners. Many famous websites use this approach.

You can also find rounded image generators around the web. One such link is http://www.generateit.net/rounded-corner/

If you are just getting into Android, you would be well served by using Android Studio rather than using any version of Eclipse. Android Studio was released in 2013 and provides a nice integrated development environment for developing for Android.

Android Studio is based on IntelliJ, which is a great java devlopment environment. It also has these specific Android features:

• Gradle-based build support.
• Android-specific refactoring and quick fixes.
• Lint tools to catch performance, usability, version compatibility and other problems.
• ProGuard and app-signing capabilities.
• Template-based wizards to create common Android designs and components.
• A rich layout editor that allows you to drag-and-drop UI components, preview layouts on multiple screen configurations, and much more.

You can download it here.

Unfortunately what you'd like to do is not possible. GraphQL requires you to be explicit about specifying which fields you would like returned from your query.

In Angular 6, you can do this:

In your service file:

 function_name(data) {
    const url = `the_URL`;
    let input = new FormData();
    input.append('url', data);   // "url" as the key and "data" as value
    return this.http.post(url, input).pipe(map((resp: any) => resp));
  }

In component.ts file: in any function say xyz,

xyz(){
this.Your_service_alias.function_name(data).subscribe(d => {   // "data" can be your file or image in base64 or other encoding
      console.log(d);
    });
}

Assuming you are calling this in an Activity class

Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image);

The first parameter, Resources, is required. It is normally obtainable in any Context (and subclasses like Activity).

Actually, to query the team_name, just add it in brackets to the last line. Apart from that, it seems to work on Python 2.7.3 on command line.

from urllib2 import urlopen
import json

url = 'http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1'
response = urlopen(url)
json_obj = json.load(response)

for i in json_obj['team']:
    print i['team_name']

Christian's answer works well and shows how you can loop through each hash table item using the GetEnumerator method. You can also loop through using the keys property. Here is an example how:

$hash = @{
    a = 1
    b = 2
    c = 3
}
$hash.Keys | % { "key = $_ , value = " + $hash.Item($_) }

Output:

key = c , value = 3
key = a , value = 1
key = b , value = 2

This is no better than other answers, but is one more way to get the job done in a file without spaces (see comments). I find that I often need one-liners to dig through lists in text files without the extra step of using separate script files.

for word in $(cat peptides.txt); do echo $word; done

This format allows me to put it all in one command-line. Change the "echo $word" portion to whatever you want and you can issue multiple commands separated by semicolons. The following example uses the file's contents as arguments into two other scripts you may have written.

for word in $(cat peptides.txt); do cmd_a.sh $word; cmd_b.py $word; done

Or if you intend to use this like a stream editor (learn sed) you can dump the output to another file as follows.

for word in $(cat peptides.txt); do cmd_a.sh $word; cmd_b.py $word; done > outfile.txt

I've used these as written above because I have used text files where I've created them with one word per line. (See comments) If you have spaces that you don't want splitting your words/lines, it gets a little uglier, but the same command still works as follows:

OLDIFS=$IFS; IFS=$'\n'; for line in $(cat peptides.txt); do cmd_a.sh $line; cmd_b.py $line; done > outfile.txt; IFS=$OLDIFS

This just tells the shell to split on newlines only, not spaces, then returns the environment back to what it was previously. At this point, you may want to consider putting it all into a shell script rather than squeezing it all into a single line, though.

Best of luck!

Here is the code that will not download courpt files

$filename = "myfile.jpg";
$file = "/uploads/images/".$filename;

header('Content-type: application/octet-stream');
header("Content-Type: ".mime_content_type($file));
header("Content-Disposition: attachment; filename=".$filename);
while (ob_get_level()) {
    ob_end_clean();
}
readfile($file);

I have included mime_content_type which will return content type of file .

To prevent from corrupt file download i have added ob_get_level() and ob_end_clean();

This will do:

#include <fstream>
#include <iostream>
using std::fstream;

int main(int argc, char *argv[]) {
    fstream file;
    file.open("test.txt",std::ios::out);
    file << fflush;
    file.close();
}

I decided to just build controls dictionaries. Harder to maintain, might run faster than the recursive FindControl().

protected void Page_Load(object sender, EventArgs e)
{
  this.BuildControlDics();
}

private void BuildControlDics()
{
  _Divs = new Dictionary<MyEnum, HtmlContainerControl>();
  _Divs.Add(MyEnum.One, this.divOne);
  _Divs.Add(MyEnum.Two, this.divTwo);
  _Divs.Add(MyEnum.Three, this.divThree);

}

And before I get down-thumbs for not answering the OP's question...

Q: Now, my question is that is there any other way/solution to find the nested control in ASP.NET? A: Yes, avoid the need to search for them in the first place. Why search for things you already know are there? Better to build a system allowing reference of known objects.

Try this

• cd existing_repo
• git remote rename origin old-origin

In JavaScript, we can declare a new empty object in two ways:

var obj1 = new Object();  
var obj2 = {};  

I have found nothing to suggest that there is any significant difference these two with regard to how they operate behind the scenes (please correct me if i am wrong – I would love to know). However, the second method (using the object literal notation) offers a few advantages.

1. It is shorter (10 characters to be precise)
2. It is easier, and more structured to create objects on the fly
3. It doesn’t matter if some buffoon has inadvertently overridden Object

Consider a new object that contains the members Name and TelNo. Using the new Object() convention, we can create it like this:

var obj1 = new Object();  
obj1.Name = "A Person";  
obj1.TelNo = "12345"; 

The Expando Properties feature of JavaScript allows us to create new members this way on the fly, and we achieve what were intending. However, this way isn’t very structured or encapsulated. What if we wanted to specify the members upon creation, without having to rely on expando properties and assignment post-creation?

This is where the object literal notation can help:

var obj1 = {Name:"A Person",TelNo="12345"};  

Here we have achieved the same effect in one line of code and significantly fewer characters.

A further discussion the object construction methods above can be found at: JavaScript and Object Oriented Programming (OOP).

And finally, what of the idiot who overrode Object? Did you think it wasn’t possible? Well, this JSFiddle proves otherwise. Using the object literal notation prevents us from falling foul of this buffoonery.

(From http://www.jameswiseman.com/blog/2011/01/19/jslint-messages-use-the-object-literal-notation/)

Based on the above answer I've written a small extension class to work with CSS and JS files:

public static class TimestampedContentExtensions
{
    public static string VersionedContent(this UrlHelper helper, string contentPath)
    {
        var context = helper.RequestContext.HttpContext;

        if (context.Cache[contentPath] == null)
        {
            var physicalPath = context.Server.MapPath(contentPath);
            var version = @"v=" + new FileInfo(physicalPath).LastWriteTime.ToString(@"yyyyMMddHHmmss");

            var translatedContentPath = helper.Content(contentPath);

            var versionedContentPath =
                contentPath.Contains(@"?")
                    ? translatedContentPath + @"&" + version
                    : translatedContentPath + @"?" + version;

            context.Cache.Add(physicalPath, version, null, DateTime.Now.AddMinutes(1), TimeSpan.Zero,
                CacheItemPriority.Normal, null);

            context.Cache[contentPath] = versionedContentPath;
            return versionedContentPath;
        }
        else
        {
            return context.Cache[contentPath] as string;
        }
    }
}

Instead of writing something like:

<link href="@Url.Content(@"~/Content/bootstrap.min.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content(@"~/Scripts/bootstrap.min.js")"></script>

You can now write:

<link href="@Url.VersionedContent(@"~/Content/bootstrap.min.css")" rel="stylesheet" type="text/css" />
<script src="@Url.VersionedContent(@"~/Scripts/bootstrap.min.js")"></script>

I.e. simply replace Url.Content with Url.VersionedContent.

Generated URLs look something like:

<link href="/Content/bootstrap.min.css?v=20151104105858" rel="stylesheet" type="text/css" />
<script src="/Scripts/bootstrap.min.js?v=20151029213517"></script>

If you use the extension class you might want to add error handling in case the MapPath call doesn't work, since contentPath isn't a physical file.

You could simply wrap your event binding call up into a function and then invoke it twice: once on document ready and once after your event that adds the new DOM elements. If you do that you'll want to avoid binding the same event twice on the existing elements so you'll need either unbind the existing events or (better) only bind to the DOM elements that are newly created. The code would look something like this:

function addCallbacks(eles){
    eles.hover(function(){alert("gotcha!")});
}

$(document).ready(function(){
    addCallbacks($(".myEles"))
});

// ... add elements ...
addCallbacks($(".myNewElements"))

Old question, but I found this useful. Turns out, there's also a specialized class for a Dictionary using a string for both the key and the value:

private static readonly StringDictionary SegmentSyntaxErrorCodes = new StringDictionary
{
    { "1", "Unrecognized segment ID" },
    { "2", "Unexpected segment" }
};

Edit: Per Chris's comment below, using Dictionary<string, string> over StringDictionary is generally preferred but will depend on your situation. If you're dealing with an older code base, you might be limited to the StringDictionary. Also, note that the following line:

myDict["foo"]

will return null if myDict is a StringDictionary, but an exception will be thrown in case of Dictionary<string, string>. See the SO post he mentioned for more information, which is the source of this edit.

An excerpt from the RFC 2616: Hypertext Transfer Protocol -- HTTP/1.1:

The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. POST is designed to allow a uniform method to cover the following functions:

• Annotation of existing resources;
• Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;
• Providing a block of data, such as the result of submitting a form, to a data-handling process;
• Extending a database through an append operation.

to convert CString to std::string. You can use this format.

std::string sText(CW2A(CSText.GetString(), CP_UTF8 ));

excel4node is a maintained, native Excel file creator built from the official specification. It's similar to, but more maintained than mxexcel-builder mentioned in the other answer.

// Require library
var excel = require('excel4node');

// Create a new instance of a Workbook class
var workbook = new excel.Workbook();

// Add Worksheets to the workbook
var worksheet = workbook.addWorksheet('Sheet 1');
var worksheet2 = workbook.addWorksheet('Sheet 2');

// Create a reusable style
var style = workbook.createStyle({
  font: {
    color: '#FF0800',
    size: 12
  },
  numberFormat: '$#,##0.00; ($#,##0.00); -'
});

// Set value of cell A1 to 100 as a number type styled with paramaters of style
worksheet.cell(1,1).number(100).style(style);

// Set value of cell B1 to 300 as a number type styled with paramaters of style
worksheet.cell(1,2).number(200).style(style);

// Set value of cell C1 to a formula styled with paramaters of style
worksheet.cell(1,3).formula('A1 + B1').style(style);

// Set value of cell A2 to 'string' styled with paramaters of style
worksheet.cell(2,1).string('string').style(style);

// Set value of cell A3 to true as a boolean type styled with paramaters of style but with an adjustment to the font size.
worksheet.cell(3,1).bool(true).style(style).style({font: {size: 14}});

workbook.write('Excel.xlsx');

I think your question is if having an update_attribute in a before_save will lead to and endless loop (of update_attribute calls in before_save callbacks, originally triggered by an update_attribute call)

I'm pretty sure it does bypass the before_save callback since it doesn't actually save the record. You can also save a record without triggering validations by using

Model.save false

Doing the following in a command prompt works for me, also adding to my User environment variables worked fine as well:

set PATH=%PATH%;C:\Program Files\7-Zip\

In Swift, you can overload existing operators:

func > (lhs: NSDate, rhs: NSDate) -> Bool {
    return lhs.timeIntervalSinceReferenceDate > rhs.timeIntervalSinceReferenceDate
}

func < (lhs: NSDate, rhs: NSDate) -> Bool {
    return lhs.timeIntervalSinceReferenceDate < rhs.timeIntervalSinceReferenceDate
}

Then, you can compare NSDates directly with <, >, and == (already supported).

Try to add

GRANT USAGE ON SCHEMA public to readonly;

You probably were not aware that one needs to have the requisite permissions to a schema, in order to use objects in the schema.

You can use shorthand syntax as of Twig 1.12.0

{{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
{{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}

Also there is

aRange.EntireColumn.AutoFit();

See What is the difference between Range.Columns and Range.EntireColumn.

The first time you run the page, the query_age index doesn't exist because it hasn't been sent over from the form.

When you submit the form it will then exist, and it won't complain about it.

#so change
$_GET['query_age'];
#to:
(!empty($_GET['query_age']) ? $_GET['query_age'] : null);

Use summarise in the dplyr package:

library(dplyr)
summarise(df, Average = mean(col_name, na.rm = T))

note: dplyr supports both summarise and summarize.

You can wrap and unwrap exceptions this way.

class A {
    void foo() throws Exception {
        throw new Exception();
    }
};

interface Task {
    void run() throws Exception;
}

static class TaskException extends RuntimeException {
    private static final long serialVersionUID = 1L;
    public TaskException(Exception e) {
        super(e);
    }
}

void bar() throws Exception {
      Stream<A> as = Stream.generate(()->new A());
      try {
        as.forEach(a -> wrapException(() -> a.foo())); // or a::foo instead of () -> a.foo()
    } catch (TaskException e) {
        throw (Exception)e.getCause();
    }
}

static void wrapException(Task task) {
    try {
        task.run();
    } catch (Exception e) {
        throw new TaskException(e);
    }
}

I find the answer from @Austin Phillips is spot on. One small improvement I'd do is to add -o (to ignore the pid of the script itself) and match for the script with basename (ie same code can be put into any script):

if pidof -x "`basename $0`" -o $$ >/dev/null; then
    echo "Process already running"

From Version 4.0.0 on RegionUtil-methods have a new signature. For example:

RegionUtil.setBorderBottom(BorderStyle.DOUBLE,
            CellRangeAddress.valueOf("A1:B7"), sheet);

I haven't needed to turn on anti-alias because it's on by default but I have needed to turn it off. And if it can be turned off it can also be turned on.

ctx.imageSmoothingEnabled = true;

I usually shut it off when I'm working on my canvas rpg so when I zoom in the images don't look blurry.

If you want separate values for sides and top-bottom.

<table style="border-spacing: 5px 10px;">

Plain JavaScript:

document.getElementById('form_id').action; //Will retrieve it

document.getElementById('form_id').action = "script.php"; //Will set it

Using jQuery...

$("#form_id").attr("action"); //Will retrieve it

$("#form_id").attr("action", "/script.php"); //Will set it

Another good alternative is http_build_query

$data = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&');

Will print

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&baz=boom&cow=milk&php=hypertext+processor

com.sun.mail.util.MailLogger is part of JavaMail API. It is already included in EE environment (that's why you can use it on your live server), but it is not included in SE environment.

Oracle docs:

The JavaMail API is available as an optional package for use with Java SE platform and is also included in the Java EE platform.

99% that you run your tests in SE environment which means what you have to bother about adding it manually to your classpath when running tests.

If you're using maven add the following dependency (you might want to change version):

<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>javax.mail</artifactId>
    <version>1.6.0</version>
</dependency>

Incase of arrays, the base address (i.e. address of the array) is the address of the 1st element in the array. Also the array name acts as a pointer.

Consider a row of houses (each is an element in the array). To identify the row, you only need the 1st house address.You know each house is followed by the next (sequential).Getting the address of the 1st house, will also give you the address of the row.

Incase of string literals(character arrays defined at declaration), they are automatically appended by \0.

printf prints using the format specifier and the address provided. Since, you use %s it prints from the 1st address (incrementing the pointer using arithmetic) until '\0'

Maybe try kint: composer require raveren/kint "dev-master" More information: Why is my debug data unformatted?

When you write an XML layout, it will be inflated by the Android OS which basically means that it will be rendered by creating view object in memory. Let's call that implicit inflation (the OS will inflate the view for you). For instance:

class Name extends Activity{
    public void onCreate(){
         // the OS will inflate the your_layout.xml
         // file and use it for this activity
         setContentView(R.layout.your_layout);
    }
}

You can also inflate views explicitly by using the LayoutInflater. In that case you have to:

1. Get an instance of the LayoutInflater
2. Specify the XML to inflate
3. Use the returned View
4. Set the content view with returned view (above)

For instance:

LayoutInflater inflater = LayoutInflater.from(YourActivity.this); // 1
View theInflatedView = inflater.inflate(R.layout.your_layout, null); // 2 and 3
setContentView(theInflatedView) // 4

Is there something special with that directory or are you really just asking how to copy directories?

Copy recursively via CLI:

cp -R <sourcedir> <destdir>

If you're only seeing the files under the sourcedir being copied (instead of sourcedir as well), that's happening because you kept the trailing slash for sourcedir:

cp -R <sourcedir>/ <destdir>

The above only copies the files and their directories inside of sourcedir. Typically, you want to include the directory you're copying, so drop the trailing slash:

cp -R <sourcedir> <destdir>

You should use setStroke to set a stroke of the Graphics2D object.

The example at http://www.java2s.com gives you some code examples.

The following code produces the image below:

import java.awt.*;
import java.awt.geom.Line2D;
import javax.swing.*;

public class FrameTest {
    public static void main(String[] args) {
        JFrame jf = new JFrame("Demo");
        Container cp = jf.getContentPane();
        cp.add(new JComponent() {
            public void paintComponent(Graphics g) {
                Graphics2D g2 = (Graphics2D) g;
                g2.setStroke(new BasicStroke(10));
                g2.draw(new Line2D.Float(30, 20, 80, 90));
            }
        });
        jf.setSize(300, 200);
        jf.setVisible(true);
    }
}

(Note that the setStroke method is not available in the Graphics object. You have to cast it to a Graphics2D object.)

(list.Count() + 9) / 10

Everything else here is either overkill or simply wrong (except for bestsss' answer, which is awesome). We do not want the overhead of a function call (Math.Truncate(), Math.Ceiling(), etc.) when simple math is enough.

OP's question generalizes (pigeonhole principle) to:

How many boxes do I need to store x objects if only y objects fit into each box?

The solution:

1. derives from the realization that the last box might be partially empty, and
2. is (x + y - 1) ÷ y using integer division.

You'll recall from 3^rd grade math that integer division is what we're doing when we say 5 ÷ 2 = 2.

Floating-point division is when we say 5 ÷ 2 = 2.5, but we don't want that here.

Many programming languages support integer division. In languages derived from C, you get it automatically when you divide int types (short, int, long, etc.). The remainder/fractional part of any division operation is simply dropped, thus:

5 / 2 == 2

Replacing our original question with x = 5 and y = 2 we have:

How many boxes do I need to store 5 objects if only 2 objects fit into each box?

The answer should now be obvious: 3 boxes -- the first two boxes hold two objects each and the last box holds one.

(x + y - 1) ÷ y =
(5 + 2 - 1) ÷ 2 =
6 ÷ 2 =
3

So for the original question, x = list.Count(), y = 10, which gives the solution using no additional function calls:

(list.Count() + 9) / 10

Google allows you to search in the project, but not the code :(

site:https://github.com/CreateJS/EaselJS test

Here is how I solved this on ubuntu 18:

1. $ sudo docker ps -a
2. copy the container ID

For each container do:

3. $ sudo docker stop container_ID
4. $ sudo docker rm container_ID

Since Java 8 you can use the Math.floorMod() method:

Math.floorMod(-1, 2); //== 1

Note: If the modulo-value (here 2) is negative, all output values will be negative too. :)

You can use SVGKit for example.

1) Integrate it according to instructions. Drag&dropping the .framework file is fast and easy.

2) Make sure you have an Objective-C to Swift bridge file bridging-header.h with import code in it:

#import <SVGKit/SVGKit.h>
#import <SVGKit/SVGKImage.h>

3) Use the framework like this, assuming that dataFromInternet is NSData, previously downloaded from network:

let anSVGImage: SVGKImage = SVGKImage(data: dataFromInternet)
myIUImageView.image = anSVGImage.UIImage

The framework also allows to init an SVGKImage from other different sources, for example it can download image for you when you provide it with URL. But in my case it was crashing in case of unreachable url, so it turned out to be better to manage networking by myself. More info on it here.

are you parsing output of ls -l?

If you are, and you just want to get the file name

find . -iname "*[0-9]" 

If you have no choice because usrLog.txt is created by something/someone else and you absolutely must use this file, other options include

awk '/^[-d].*[0-9]$/' file

Ruby(1.9+)

ruby -ne 'print if /^[-d].*[0-9]$/' file

Bash

while read -r line ; do  case $line in [-d]*[0-9] ) echo $line;  esac; done < file

Hide #categories initially

#categories {
    display: none;
}

and then, using JQuery UI, animate the Menu slowly

var duration = 'slow';

$('#cat_icon').click(function () {
    $('#cat_icon').hide(duration, function() {
        $('#categories').show('slide', {direction: 'left'}, duration);});
});
$('.panel_title').click(function () {
    $('#categories').hide('slide', {direction: 'left'}, duration, function() {
        $('#cat_icon').show(duration);});
});

JSFiddle

You can use any time in milliseconds as well

var duration = 2000;

If you want to hide on class='panel_item' too, select both panel_title and panel_item

$('.panel_title,.panel_item').click(function () {
    $('#categories').hide('slide', {direction: 'left'}, duration, function() {
        $('#cat_icon').show(duration);});
});

JSFiddle

You can do it by MXBeans

public class Check {
    public static void main(String[] args) {
        MemoryMXBean memBean = ManagementFactory.getMemoryMXBean() ;
        MemoryUsage heapMemoryUsage = memBean.getHeapMemoryUsage();

        System.out.println(heapMemoryUsage.getMax()); // max memory allowed for jvm -Xmx flag (-1 if isn't specified)
        System.out.println(heapMemoryUsage.getCommitted()); // given memory to JVM by OS ( may fail to reach getMax, if there isn't more memory)
        System.out.println(heapMemoryUsage.getUsed()); // used now by your heap
        System.out.println(heapMemoryUsage.getInit()); // -Xms flag

        // |------------------ max ------------------------| allowed to be occupied by you from OS (less than xmX due to empty survival space)
        // |------------------ committed -------|          | now taken from OS
        // |------------------ used --|                    | used by your heap

    }
}

But remember it is equivalent to Runtime.getRuntime() (took depicted schema from here)

memoryMxBean.getHeapMemoryUsage().getUsed()      <=> runtime.totalMemory() - runtime.freeMemory()
memoryMxBean.getHeapMemoryUsage().getCommitted() <=> runtime.totalMemory()
memoryMxBean.getHeapMemoryUsage().getMax()       <=> runtime.maxMemory()

from javaDoc

init - represents the initial amount of memory (in bytes) that the Java virtual machine requests from the operating system for memory management during startup. The Java virtual machine may request additional memory from the operating system and may also release memory to the system over time. The value of init may be undefined.

used - represents the amount of memory currently used (in bytes).

committed - represents the amount of memory (in bytes) that is guaranteed to be available for use by the Java virtual machine. The amount of committed memory may change over time (increase or decrease). The Java virtual machine may release memory to the system and committed could be less than init. committed will always be greater than or equal to used.

max - represents the maximum amount of memory (in bytes) that can be used for memory management. Its value may be undefined. The maximum amount of memory may change over time if defined. The amount of used and committed memory will always be less than or equal to max if max is defined. A memory allocation may fail if it attempts to increase the used memory such that used > committed even if used <= max would still be true (for example, when the system is low on virtual memory).

    +----------------------------------------------+
    +////////////////           |                  +
    +////////////////           |                  +
    +----------------------------------------------+

    |--------|
       init

           used
    |---------------------------|
              committed
    |----------------------------------------------|
                        max

As additional note, maxMemory is less than -Xmx because there is necessity at least in one empty survival space, which can't be used for heap allocation.

also it is worth to to take a look at here and especially here

Srsly guys... Why so many lines of code for a simple method like this? Here's my solution:

Stuzor and hexcodes solution worked for me as well. However, if you do want the latest connector you have to download another product. From the oracle website:

Starting with version 6.7, Connector/Net will no longer include the MySQL for Visual Studio integration. That functionality is now available in a separate product called MySQL for Visual Studio available using the MySQL Installer for Windows (see http://dev.mysql.com/tech-resources/articles/mysql-installer-for-windows.html).

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

I haven't tried it but if you put a div in your table cell set so that it will have scrollbars if needed, then you could insert in there, with a fixed height on the div and it should keep your table row to a fixed height.

Although it should be unecessary to do this in anything other than exceptional circumstances, the recommended way to do this on linux hosts is to unload the nvidia driver by doing

$ rmmod nvidia 

with suitable root privileges and then reloading it with

$ modprobe nvidia

If the machine is running X11, you will need to stop this manually beforehand, and restart it afterwards. The driver intialisation processes should eliminate any prior state on the device.

I also encountered this problem when I was working on my project. I really wish they provide an end api method. Anyway, This is how I did it: When you are uploading an image to Firebase storage, create an Object and pass this object to Firebase database at the same time. This object contains the download URI of the image.

trailsRef.putFile(file).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Uri downloadUri = taskSnapshot.getDownloadUrl();
            DatabaseReference myRef = database.getReference().child("trails").child(trail.getUnique_id()).push();
            Image img = new Image(trail.getUnique_id(), downloadUri.toString());
            myRef.setValue(img);
        }
    });

Later when you want to download images from a folder, you simply iterate through files under that folder. This folder has the same name as the "folder" in Firebase storage, but you can name them however you want to. I put them in separate thread.

 @Override
protected List<Image> doInBackground(Trail... params) {

    String trialId = params[0].getUnique_id();
    mDatabase = FirebaseDatabase.getInstance().getReference();
    mDatabase.child("trails").child(trialId).addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            images = new ArrayList<>();
            Iterator<DataSnapshot> iter = dataSnapshot.getChildren().iterator();
            while (iter.hasNext()) {
                Image img = iter.next().getValue(Image.class);
                images.add(img);
            }
            isFinished = true;
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });

Now I have a list of objects containing the URIs to each image, I can do whatever I want to do with them. To load them into imageView, I created another thread.

    @Override
protected List<Bitmap> doInBackground(List<Image>... params) {

    List<Bitmap> bitmaps = new ArrayList<>();

    for (int i = 0; i < params[0].size(); i++) {
        try {
            URL url = new URL(params[0].get(i).getImgUrl());
            Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
            bitmaps.add(bmp);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    return bitmaps;
}

This returns a list of Bitmap, when it finishes I simply attach them to ImageView in the main activity. Below methods are @Override because I have interfaces created and listen for completion in other threads.

    @Override
public void processFinishForBitmap(List<Bitmap> bitmaps) {
    List<ImageView> imageViews = new ArrayList<>();
    View v;
    for (int i = 0; i < bitmaps.size(); i++) {
        v = mInflater.inflate(R.layout.gallery_item, mGallery, false);
        imageViews.add((ImageView) v.findViewById(R.id.id_index_gallery_item_image));
        imageViews.get(i).setImageBitmap(bitmaps.get(i));
        mGallery.addView(v);
    }
}

Note that I have to wait for List Image to be returned first and then call thread to work on List Bitmap. In this case, Image contains the URI.

    @Override
public void processFinish(List<Image> results) {
    Log.e(TAG, "get back " + results.size());

    LoadImageFromUrlTask loadImageFromUrlTask =  new LoadImageFromUrlTask();
    loadImageFromUrlTask.delegate = this;
    loadImageFromUrlTask.execute(results);
}

Hopefully someone finds it helpful. It will also serve as a guild line for myself in the future too.

In my case when I get this message IE suggest me to install add-on from Microsoft. After install problem solved.

You can use eval() for this purpose

>>> url = "'http address'"
>>> eval(url)
'http address'

while eval() poses risk , i think in this context it is safe.

I know it is a very old question, but better update it with new information.

You can install service by using sc command:

InstallService.bat:

@echo OFF
echo Stopping old service version...
net stop "[YOUR SERVICE NAME]"
echo Uninstalling old service version...
sc delete "[YOUR SERVICE NAME]"

echo Installing service...
rem DO NOT remove the space after "binpath="!
sc create "[YOUR SERVICE NAME]" binpath= "[PATH_TO_YOUR_SERVICE_EXE]" start= auto
echo Starting server complete

With SC, you can do a lot more things as well: uninstalling the old service (if you already installed it before), checking if service with same name exists... even set your service to autostart.

One of many references: creating a service with sc.exe; how to pass in context parameters

I have done by both this way & InstallUtil. Personally I feel that using SC is cleaner and better for your health.

Let foo be a function that does not "return" (echo) a value, but it sets the exit code as usual.
To avoid checking $status after calling the function, you can do:

foo; and echo success; or echo failure

And if it's too long to fit on one line:

foo; and begin
  echo success
end; or begin
  echo failure
end

The simple answer is yes - new() creates an object on the heap (with the unfortunate side effect that you have to manage its lifetime (by explicitly calling delete on it), whereas the second form creates an object in the stack in the current scope and that object will be destroyed when it goes out of scope.

You need to access the layout via it's layout resource, not an id resource which is not guaranteed unique. The resource reference should look like R.layout.my_cool_layout where your above XML layout is stored in res/layout/my_cool_layout.xml.

The naming convention is part of the well-established JavaBeans specification and is supported by the classes in the java.beans package.

Are you after something like this:

 <html>
 <head>
    <title>Z Test</title>
 </head>
 <body>

<div id="img_home"></div>

<button onclick="addimage()" type="button">Add an image</button>

<script>
function addimage() {
    var img = new Image();
    img.src = "https://www.google.com/images/srpr/logo4w.png"
    img_home.appendChild(img);
}
</script>
</body>

There are loads of different design patterns used, but there are a few obvious ones:

• Proxy - used heavily in AOP, and remoting.

• Singleton - beans defined in spring config files are singletons by default.

• Template method - used extensively to deal with boilerplate repeated code (such as closing connections cleanly, etc..). For example JdbcTemplate, JmsTemplate, JpaTemplate.

Update following comments: For MVC, you might want to read the MVC Reference

Some obvious patterns in use in MVC:

• Model View Controller :-) . The advantage with Spring MVC is that your controllers are POJOs as opposed to being servlets. This makes for easier testing of controllers. One thing to note is that the controller is only required to return a logical view name, and the view selection is left to a separate ViewResolver. This makes it easier to reuse controllers for different view technologies.

• Front Controller. Spring provides DispatcherServlet to ensure an incoming request gets dispatched to your controllers.

• View Helper - Spring has a number of custom JSP tags, and velocity macros, to assist in separating code from presentation in views.

You can also specify the version of Boost that you would like CMake to use by passing -DBOOST_INCLUDEDIR or -DBOOST_ROOT pointing to the location of correct version boost headers

Example:

cmake -DBOOST_ROOT=/opt/latestboost

This will also be useful when multiple boost versions are on the same system.

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)

Syntax to change column name in MySql:

alter table table_name change old_column_name new_column_name data_type(size);

Example:

alter table test change LowSal Low_Sal integer(4);

For the JSON library to be available, you may have to install libjson-ruby from your package manager.

To use the 'json' library:

require 'json'

To convert an object to JSON (these 3 ways are equivalent):

JSON.dump object #returns a JSON string
JSON.generate object #returns a JSON string
object.to_json #returns a JSON string

To convert JSON text to an object (these 2 ways are equivalent):

JSON.load string #returns an object
JSON.parse string #returns an object

It will be a bit more difficult for objects from your own classes. For the following class, to_json will produce something like "\"#<A:0xb76e5728>\"".

class A
    def initialize a=[1,2,3], b='hello'
        @a = a
        @b = b
    end
end

This probably isn't desirable. To effectively serialise your object as JSON, you should create your own to_json method. To go with this, a from_json class method would be useful. You could extend your class like so:

class A
    def to_json
        {'a' => @a, 'b' => @b}.to_json
    end
    def self.from_json string
        data = JSON.load string
        self.new data['a'], data['b']
    end
end

You could automate this by inheriting from a 'JSONable' class:

class JSONable
    def to_json
        hash = {}
        self.instance_variables.each do |var|
            hash[var] = self.instance_variable_get var
        end
        hash.to_json
    end
    def from_json! string
        JSON.load(string).each do |var, val|
            self.instance_variable_set var, val
        end
    end
end

Then you can use object.to_json to serialise to JSON and object.from_json! string to copy the saved state that was saved as the JSON string to the object.

protected void gvBill_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)

            Total += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "InvMstAmount"));
        else if (e.Row.RowType == DataControlRowType.Footer)

            e.Row.Cells[7].Text = String.Format("{0:0}", "<b>" + Total + "</b>");
    }

Since in your situation you only want to notify the user with a short and simple message, a Toast would make for a better user experience.

Toast.makeText(getApplicationContext(), "Data saved", Toast.LENGTH_LONG).show();

Update: A Snackbar is recommended now instead of a Toast for Material Design apps.

If you have a more lengthy message that you want to give the reader time to read and understand, then you should use a DialogFragment. (The documentation currently recommends wrapping your AlertDialog in a fragment rather than calling it directly.)

Make a class that extends DialogFragment:

public class MyDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        // Use the Builder class for convenient dialog construction
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("App Title");
        builder.setMessage("This is an alert with no consequence");
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // You don't have to do anything here if you just 
                // want it dismissed when clicked
            }
        });

        // Create the AlertDialog object and return it
        return builder.create();
    }
}

Then call it when you need it in your activity:

DialogFragment dialog = new MyDialogFragment();
dialog.show(getSupportFragmentManager(), "MyDialogFragmentTag");

You need to use the Graphics class in order to write on the bitmap.

Specifically, one of the DrawString methods.

}

pictuteBox1.Image = a;

To be able to pass the select, I just set it back to :

  $('#selectID').prop('disabled',false);

or

  $('#selectID').attr('disabled',false);

when passing the request.

The hide selector was incorrect. I hid the blocks at page load and showed the selected value. I also changed the car div id's to make it easier to append the radio button value and create the proper id selector.

<div id="myRadioGroup">
  2 Cars<input type="radio" name="cars" checked="checked" value="2"  />
  3 Cars<input type="radio" name="cars" value="3" />
  <div id="car-2">
  2 Cars
  </div>
  <div id="car-3">
  3 Cars
  </div>
</div>

<script type="text/javascript">
$(document).ready(function(){ 
  $("div div").hide();
  $("#car-2").show();
  $("input[name$='cars']").click(function() {
      var test = $(this).val();
      $("div div").hide();
      $("#car-"+test).show();
  }); 
});
</script>

Create a function like so:

CREATE FUNCTION dbo.fn_FileExists(@path varchar(512))
RETURNS BIT
AS
BEGIN
     DECLARE @result INT
     EXEC master.dbo.xp_fileexist @path, @result OUTPUT
     RETURN cast(@result as bit)
END;
GO

Edit your table and add a computed column (IsExists BIT). Set the expression to:

dbo.fn_FileExists(filepath)

Then just select:

SELECT * FROM dbo.MyTable where IsExists = 1

Update:

To use the function outside a computed column:

select id, filename, dbo.fn_FileExists(filename) as IsExists
from dbo.MyTable

Update:

If the function returns 0 for a known file, then there is likely a permissions issue. Make sure the SQL Server's account has sufficient permissions to access the folder and files. Read-only should be enough.

And YES, by default, the 'NETWORK SERVICE' account will not have sufficient right into most folders. Right click on the folder in question and select 'Properties', then click on the 'Security' tab. Click 'Edit' and add 'Network Service'. Click 'Apply' and retest.

json_encode() will only encode public member variables. so if you want to include the private once you have to do it by yourself (as the others suggested)

As I outline in this other answer here on StackOverflow, you can do this by timing the download of files of various sizes (start small, ramp up if the connection seems to allow it), ensuring through cache headers and such that the file is really being read from the remote server and not being retrieved from cache. This doesn't necessarily require that you have a server of your own (the files could be coming from S3 or similar), but you will need somewhere to get the files from in order to test connection speed.

That said, point-in-time bandwidth tests are notoriously unreliable, being as they are impacted by other items being downloaded in other windows, the speed of your server, links en route, etc., etc. But you can get a rough idea using this sort of technique.

Even DRYer way!

@mixin box-shadow($args...) {
  @each $pre in -webkit-, -moz-, -ms-, -o- {
    #{$pre + box-shadow}: $args;
  } 
  #{box-shadow}: #{$args};
}

And now you can reuse your box-shadow even smarter:

.myShadow {
  @include box-shadow(2px 2px 5px #555, inset 0 0 0);
}

The indentation is wrong, as the error tells you. As you can see, you have indented the code beginning with the indicated line too little to be in the for loop, but too much to be at the same level as the for loop. Python sees the lack of indentation as ending the for loop, then complains you have indented the rest of the code too much. (The def line I'm betting is just an artifact of how Stack Overflow wants you to format your code.)

Edit: Given your correction, I'm betting you have a mixture of tabs and spaces in the source file, such that it looks to the human eye like the code lines up, but Python considers it not to. As others have suggested, using only spaces is the recommended practice (see PEP 8). If you start Python with python -t, you will get warnings if there are mixed tabs and spaces in your code, which should help you pinpoint the issue.

or is NOT the same as ||. Use only || operator instead of the or operator.

Here are some reasons. The:

• or operator has a lower precedence than ||.
• or has a lower precedence than the = assignment operator.
• and and or have the same precedence, while && has a higher precedence than ||.

Like you have mentioned, The default -Xmxsize (Maximum HeapSize) depends on your system configuration.

Java8 client takes Larger of 1/64th of your physical memory for your Xmssize (Minimum HeapSize) and Smaller of 1/4th of your physical memory for your -Xmxsize (Maximum HeapSize).

Which means if you have a physical memory of 8GB RAM, you will have Xmssize as Larger of 8*(1/6) and Smaller of -Xmxsizeas 8*(1/4).

You can Check your default HeapSize with

In Windows:

java -XX:+PrintFlagsFinal -version | findstr /i "HeapSize PermSize ThreadStackSize"

In Linux:

java -XX:+PrintFlagsFinal -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'

These default values can also be overrided to your desired amount.

Well you could get the ip address using asp.net, then do a reverse DNS lookup on the ip to get the hostname.

From the ASP.NET Developer's cookbook ... Performing a Reverse-DNS Lookup.

This is more understandable:

git checkout 56e05fced -- .

Consider if your XML looks like below.

<Employees Id="1" Name="ABC">
  <Query>
    SELECT * FROM EMP WHERE ID=1 AND RES<>'GCF'
  <Query>
</Employees>

You cannot use the <> directly as it throws an error. In that case, you can use <> in replacement of that.

<Employees Id="1" Name="ABC">
  <Query>
    SELECT * FROM EMP WHERE ID=1 AND RES &#60;&#62; 'GCF'
  <Query>
</Employees>

On your aspx page define the HTML Button element with the usual suspects: runat, class, title, etc.

If this element is part of a data bound control (i.e.: grid view, etc.) you may want to use CommandName and possibly CommandArgument as attributes. Add your button's content and closing tag.

<button id="cmdAction" 
    runat="server" onserverclick="cmdAction_Click()" 
    class="Button Styles" 
    title="Does something on the server" 
    <!-- for databound controls -->
    CommandName="cmdname"> 
    CommandArgument="args..."
    >
    <!-- content -->
    <span class="ui-icon ..."></span>
    <span class="push">Click Me</span>
</button>

On the code behind page the element would call the handler that would be defined as the element's ID_Click event function.

protected void cmdAction_Click(object sender, EventArgs e)
{
: do something.
}

There are other solutions as in using custom controls, etc. Also note that I am using this live on projects in VS2K8.

Hoping this helps. Enjoy!

I fixed similar issues by qutating column name

SELECT * from table_name where "foo" is NULL;

In my case it was just

SELECT id, "foo" from table_name;

without quotes i'v got same error.

At your parent DIV add

display:table;

and at your child element add

 display:table-cell;
 vertical-align:middle;

You can also just use the top command and your user ID will indicate the jobs running and the their times.

$ top

(this will show all running jobs)

$ top -U [user ID]

(This will show jobs that are specific for the user ID)

You can also compare with double value

BigDecimal a= new BigDecimal("1.1"); BigDecimal b =new BigDecimal("1.1");
System.out.println(a.doubleValue()==b.doubleValue());

This worked for me :

Added a custom container class :

@Component
public class CustomContainer implements EmbeddedServletContainerCustomizer {

    @Override
    public void customize(ConfigurableEmbeddedServletContainer configurableEmbeddedServletContainer) {
       configurableEmbeddedServletContainer.setPort(8888);
    }

}

But this was still not using port 8888.

Then I set "scanBasePackages" property like this on "@SpringBootApplication" class on my main method: (scanBasePackages = {"custom container package"})

@SpringBootApplication(scanBasePackages = {"com.javabrains.util"})
public class CourseApiApp {

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

And it started picking up port set in Custom Container.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

You can use count too. It will return the number of items present in a vector.

int t=count(vec.begin(),vec.end(),item);

Run cat -v file.sh.

You most likely have a carriage return or no-break space in your file. cat -v will show them as ^M and M-BM- or M- respectively. It will similarly show any other strange characters you might have gotten into your file.

Remove the Windows line breaks with

tr -d '\r' < file.sh > fixedfile.sh

To get a fully independent copy of an object you can use the copy.deepcopy() function.

For more details about shallow and deep copying please refer to the other answers to this question and the nice explanation in this answer to a related question.

when you pushing code to another branch just follow the below git command. Remember demo is my other branch name you can replace with your branch name.

As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.

As long as you are sure you are not doing anything wrong, kindly terminate "ng serve" and restart it. By so doing, the compiler does all of its work and the app serves as expected. Prior experiences with modules have taught me to either create them when "ng serve" is not running or to restart the terminal once I'm done.

Restarting "ng serve" also works when you're emitting a new component to another component, it's possible the compiler has not recognised your new component, simply restart "ng serve"

This worked for me just a few minutes ago.

I was getting this error on a Spring Boot application where a @RestController ApplicationInfoResource had a nested class ApplicationInfo.

It seems the Spring Boot Dev Tools was using a different class loader.

The exception I was getting

2017-05-01 17:47:39.588 WARN 1516 --- [nio-8080-exec-9] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.IllegalAccessError: tried to access class com.gt.web.rest.ApplicationInfo from class com.gt.web.rest.ApplicationInfoResource$$EnhancerBySpringCGLIB$$59ce500c

Solution

I moved the nested class ApplicationInfo to a separate .java file and got rid of the problem.

Disclaimer- The main source of some definitions are wikipedia, any suggestion to improve my answer is welcome.

Although this post has an accepted answer and is a good one I was still in confusion and would like to add some more clarification regarding the difference between these terms.

(1)FULL BINARY TREE- A full binary tree is a binary tree in which every node other than the leaves has two children.This is also called strictly binary tree.

The above two are the examples of full or strictly binary tree.

(2)COMPLETE BINARY TREE- Now, the definition of complete binary tree is quite ambiguous, it states :- A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible. It can have between 1 and 2h nodes, as far left as possible, at the last level h

Notice the lines in italic.

The ambiguity lies in the lines in italics , "except possibly the last" which means that the last level may also be completely filled , i.e this exception need not always be satisfied. If the exception doesn't hold then it is exactly like the second image I posted, which can also be called as perfect binary tree. So, a perfect binary tree is also full and complete but not vice-versa which will be clear by one more definition I need to state:

ALMOST COMPLETE BINARY TREE- When the exception in the definition of complete binary tree holds then it is called almost complete binary tree or nearly complete binary tree . It is just a type of complete binary tree itself , but a separate definition is necessary to make it more unambiguous.

So an almost complete binary tree will look like this, you can see in the image the nodes are as far left as possible so it is more like a subset of complete binary tree , to say more rigorously every almost complete binary tree is a complete binary tree but not vice versa . :

here you can specify whichever field you want in your output and also which you don't.
  
  POST index_name/_search
    {
        "_source": {
            "includes": [ "field_name", "field_name" ],
            "excludes": [ "field_name" ]
        },
        "query" : {
            "match" : { "field_name" : "value" }
        }
    }

I think it depends on the operations you'll be needing to do most frequently.

If you need the full value as a decimal number, then use decimal with appropriate precision and scale. Float is way beyond your needs, I believe.

If you'll be converting to/from degºmin'sec"fraction notation often, I'd consider storing each value as an integer type (smallint, tinyint, tinyint, smallint?).

This error occurs if you are using the wrong path.

For e.g:

I'm using ubuntu system and my project folder name is 'myproject'

Suppose I have myproject/public/report directory exist and want to create a new folder called orders

Then I need a whole path where my project exists. You can get the path by PWD command

So my root path will be = '/home/htdocs/myproject/'

$dir = '/home/htdocs/myproject/public/report/Orders';

if (!is_dir($dir)) {
   mkdir($dir, 0775, true);
}

It will work for you !! Enjoy !!

The KeyDown event only triggered at the standard TextBox or MaskedTextBox by "normal" input keys, not ENTER or TAB and so on.

One can get special keys like ENTER by overriding the IsInputKey method:

public class CustomTextBox : System.Windows.Forms.TextBox
{
    protected override bool IsInputKey(Keys keyData)
    {
        if (keyData == Keys.Return)
            return true;
        return base.IsInputKey(keyData);
    }
}

Then one can use the KeyDown event in the following way:

CustomTextBox ctb = new CustomTextBox();
ctb.KeyDown += new KeyEventHandler(tb_KeyDown);

private void tb_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
          //Enter key is down

          //Capture the text
          if (sender is TextBox)
          {
              TextBox txb = (TextBox)sender;
              MessageBox.Show(txb.Text);
          }
    }
}

Can't believe this thread was going on for so long. You would get this error if you got distracted and used [] instead of (), at least my case.

Pop is a method on the list data type, https://docs.python.org/2/tutorial/datastructures.html#more-on-lists

Therefore, you shouldn't be using pop as if it was a list itself, pop[0]. It's a method that takes an optional parameter representing an index, so as Tushar Palawat pointed out in one of the answers that didn't get approved, the correct adjustment which will fix the example above is:

listb.pop(0)

If you don't believe, run a sample such as:

if __name__ == '__main__':
  listb = ["-test"]
  if( listb[0] == "-test"):
    print(listb.pop(0))

Other adjustments would work as well, but it feels as they are abusing the Python language. This thread needs to get fixed, not to confuse users.

Addition, a.pop() removes and returns the last item in the list. As a result, a.pop()[0] will get the first character of that last element. It doesn't seem that is what the given code snippet is aiming to achieve.

You are trying to use the wrong interface type. The type Function is not appropriate in this case because it receives a parameter and has a return value. Instead you should use Consumer (formerly known as Block)

The Function type is declared as

interface Function<T,R> {
  R apply(T t);
}

However, the Consumer type is compatible with that you are looking for:

interface Consumer<T> {
   void accept(T t);
}

As such, Consumer is compatible with methods that receive a T and return nothing (void). And this is what you want.

For instance, if I wanted to display all element in a list I could simply create a consumer for that with a lambda expression:

List<String> allJedi = asList("Luke","Obiwan","Quigon");
allJedi.forEach( jedi -> System.out.println(jedi) );

You can see above that in this case, the lambda expression receives a parameter and has no return value.

Now, if I wanted to use a method reference instead of a lambda expression to create a consume of this type, then I need a method that receives a String and returns void, right?.

I could use different types of method references, but in this case let's take advantage of an object method reference by using the println method in the System.out object, like this:

Consumer<String> block = System.out::println

Or I could simply do

allJedi.forEach(System.out::println);

The println method is appropriate because it receives a value and has a return type void, just like the accept method in Consumer.

So, in your code, you need to change your method signature to somewhat like:

public static void myForEach(List<Integer> list, Consumer<Integer> myBlock) {
   list.forEach(myBlock);
}

And then you should be able to create a consumer, using a static method reference, in your case by doing:

myForEach(theList, Test::displayInt);

Ultimately, you could even get rid of your myForEach method altogether and simply do:

theList.forEach(Test::displayInt);

About Functions as First Class Citizens

All been said, the truth is that Java 8 will not have functions as first-class citizens since a structural function type will not be added to the language. Java will simply offer an alternative way to create implementations of functional interfaces out of lambda expressions and method references. Ultimately lambda expressions and method references will be bound to object references, therefore all we have is objects as first-class citizens. The important thing is the functionality is there since we can pass objects as parameters, bound them to variable references and return them as values from other methods, then they pretty much serve a similar purpose.
