Example JS Fiddle

Bullets take the color property of the list:

.listStyle {
    color: red;
}

Note if you want your list text to be a different colour, you have to wrap it in say, a p, for example:

.listStyle p {
    color: black;
}

Example HTML:

<ul class="listStyle">
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
</ul>

This appears to be my "preferred" solution:

<form action="www.spufalcons.com/index.aspx?tab=gymnastics&path=gym" method="post">  <div>
<input type="submit" value="Gymnastics"></div>

Sorry for the presentation format - I'm still trying to learn how to use this forum....

I do have a follow-up question. In looking at my MySQL database of URL's it appears that ~30% of the URL's will need to use this post/div wrapper approach. This leaves ~70% that cannot accept the "post" attribute. For example:

<form action="http://www.google.com" method="post">
  <div>
    <input type="submit" value="Google"/>
  </div></form>

does not work. Do you have a recommendation for how to best handle this get/post condition test. Off the top of my head I'm guessing that using PHP to evaluate the existence of the "?" character in the URL may be my best approach, although I'm not sure how to structure the HTML form to accomplish this.

Thank YOU!

Another option is to use Javascript:

if (document.getElementById('selectID').value == '1') {
       document.getElementById('optionID').style.color = '#000';

(Not as clean as the CSS attribute selector, but more powerful)

I found the example above confusing. I am using React and JSX so I think it complicated the scenario.

I got clarification from TypeScript Deep Dive, which states for arrow generics:

Workaround: Use extends on the generic parameter to hint the compiler that it's a generic, this came from a simpler example that helped me.

    const identity = < T extends {} >(arg: T): T => { return arg; }

I saw a lot of examples here where no real work was being performed, and they were mostly CPU-bound. Here is an example of a CPU-bound task that computes all prime numbers between 10 million and 10.05 million. I have used all four methods here:

    return wrapper

        found = False

        # Check if the any number from 2 to the square root + 1 divides the current numnber under consideration
        for number in range(2, sqrt_n + 1):

            # If divisible we have found a factor, hence this is not a prime number, lets move to the next one

I have the same issue, my application was running on amazon vps, lately i found that bin folder had multiple copies of dll's ... After removing those copies of dlls like entityframework(copy1).dll, errors were gone.... May be some one will get help...cheers

RadioGroup radioGroup = new RadioGroup(context);
RadioButton radioBtn1 = new RadioButton(context);
RadioButton radioBtn2 = new RadioButton(context);
RadioButton radioBtn3 = new RadioButton(context);

radioBtn1.setText("Less");
radioBtn2.setText("Normal");
radioBtn3.setText("More");

radioGroup.addView(radioBtn1);
radioGroup.addView(radioBtn2);
radioGroup.addView(radioBtn3);
radioBtn2.setChecked(true);

I had a CASE statement with WHEN column = 'sometext & more text' THEN ....

I replaced it with WHEN column = 'sometext ' || CHR(38) || ' more text' THEN ...

you could also use WHEN column LIKE 'sometext _ more text' THEN ...

(_ is the wildcard for a single character)

Old thread, but the question is still relevant, so...

(1) The example in your question now DOES work in Firefox. However in addition to calling the event handler (which displays an alert), it ALSO clicks on the link, causing navigation (once the alert is dismissed).

(2) To JUST call the event handler (without triggering navigation) merely replace:

document.getElementById('linkid').click();

with

document.getElementById('linkid').onclick();

Run the command using the windows command prompt from your main Python library source. Example.

C:\Python27\python.exe directoryToFile\yourprogram.py

#if !defined(MANUF) || !defined(SERIAL) || !defined(MODEL)

Set up a System variable from Maven and in java use following call

System.getProperty("Key");

If you are using ng-show to limit the values, the {{$last ? '' : ', '}} won`t work since it will still take into consideration all the values.Example

<div ng-repeat="x in records" ng-show="x.email == 1">{{x}}{{$last ? '' : ', '}}</div>

var myApp = angular.module("myApp", []);
myApp.controller("myCtrl", function($scope) {
  $scope.records = [
    {"email": "1"},
    {"email": "1"},
    {"email": "2"},
    {"email": "3"}
  ]
});

Results in adding a comma after the "last" value,since with ng-show it still takes into consideration all 4 values

{"email":"1"},
{"email":"1"},

One solution is to add a filter directly into ng-repeat

<div ng-repeat="x in records | filter: { email : '1' } ">{{x}}{{$last ? '' : ', '}}</div>

Results

{"email":"1"},
{"email":"1"}

You can always create an ArrayList of Objects. But it will not be very useful to you. Suppose you have created the Arraylist like this:

List<Object> myList = new ArrayList<Object>();

and add objects to this list like this:

myList.add(new Integer("5"));

myList.add("object");

myList.add(new Object());

You won't face any problem while adding and retrieving the object but it won't be very useful. You have to remember at what location each type of object is it in order to use it. In this case after retrieving, all you can do is calling the methods of Object on them.

I was looking for the same, simple local storage but also with a reasonable level of security. The two solutions I've found that make the most sense are flutter_secure_storage (as mentioned by Raouf) for the small stuff, and hive for larger datasets.

Well java.lang.Exception extends java.lang.Throwable. java.io.FileNotFoundException extends java.lang.Exception. So if a method throws java.io.FileNotFoundException then in the override method you cannot throw anything higher up the hierarchy than FileNotFoundException e.g. you can't throw java.lang.Exception. You could throw a subclass of FileNotFoundException though. However you would be forced to handle the FileNotFoundException in the overriden method. Knock up some code and give it a try!

The rules are there so you don't lose the original throws declaration by widening the specificity, as the polymorphism means you can invoke the overriden method on the superclass.

For a non-specific package and a more general solution you can check out pip-review, a tool that checks what packages could/should be updated.

$ pip-review --interactive
requests==0.14.0 is available (you have 0.13.2)
Upgrade now? [Y]es, [N]o, [A]ll, [Q]uit y

For me changing createLBPHFaceRecognizer() to

recognizer = cv2.face.LBPHFaceRecognizer_create()

fixed the problem

If you just want to remove one of a group of variables, then you can create a list and keep just the variable you need. The rm function can be used to remove all the variables apart from "data". Here is the script:

0->data
1->data_1
2->data_2
3->data_3
#check variables in workspace
ls()
rm(list=setdiff(ls(), "data"))
#check remaining variables in workspace after deletion
ls()

#note: if you just use rm(list) then R will attempt to remove the "list" variable. 
list=setdiff(ls(), "data")
rm(list)
ls()

I think I have figured it out, is it right?:

mysql_query("START TRANSACTION");

$a1 = mysql_query("INSERT INTO rarara (l_id) VALUES('1')");
$a2 = mysql_query("INSERT INTO rarara (l_id) VALUES('2')");

if ($a1 and $a2) {
    mysql_query("COMMIT");
} else {        
    mysql_query("ROLLBACK");
}

.toggleClass() will not animate, you should go for slideToggle() or .animate() method.

For TypeScript users, if you are importing a built-in Node module (such as http, path or url) and you are getting an error such as "Cannot find module "x" then the error can be fixed by running

npm install @types/node --save-dev

The command will import the NodeJS TypeScript definitions into your project, allowing you to use Node's built-in modules.

Kdiff3 conflict resolution algorithm is really impressive.

Even when subversion indicates a conflict, Kdiff3 solves it automatically. There's versions for Windows and Linux with the same interface. It is possible to integrate it with Tortoise and with your linux shell.

It is in the list of my favorite open source software. One of the first tools I install in any machine.

You can configure it as the default diff tool in Subversion, Git, Mercurial, and ClearCase. It also solves almost all the ClearCase conflicts. In Windows, it has a nice integration with windows explorer: select two files and right click to compare them, or right click to 'save to later' a file, and then select another one to compare.

The merged file is editable. Has slick keyboard shortcuts.

You can also use it compare and merge directories. See:

An advanced feature is to use regular expressions for defining automatic merges.

My only annoyance is that it is a little difficult to compile if it isn't present in your favorite distro repository.

Go to form's properties, ICON ... Choose an icon you want.

EDIT: try this

1. Edit App.Ico to make it look like you want.
2. In the property pane for your form, set the Icon property to your project's App.Ico file.
3. Rebuild solution.

And read this one icons

• the custom class must implement the == operator
• must create a hash function for the class (for primitive types like int and also types like string the hash function is predefined)

A one-rule version:

var val = example[function() { for (var k in example) return k }()];

This answer is actually taken from Scott Allen's course titled ASP.NET MVC 5 Fundamentals. I thought I'd share because I think it is slightly simpler and more intuitive than any of the answers here already. Also note according to Scott Allen and other trainings I've done, find method is an optimized way to retrieve a resource from database that can use caching if it already has been retrieved. In this code, collection refers to a DBSet of objects. Object can be any generic object type.

        var object = context.collection.Find(id);  
        context.collection.Remove(object);
        context.SaveChanges();

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

I know this is a old question but here is another solution that works for me

SET @dtDate = "your date"
DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@dtDate)+1,0))

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView {

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

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

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

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth();
        @SuppressWarnings("unused")
        int h = getHeight();

        Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
        Bitmap sbmp;

        if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
            float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
            float factor = smallest / radius;
            sbmp = Bitmap.createScaledBitmap(bmp,
                    (int) (bmp.getWidth() / factor),
                    (int) (bmp.getHeight() / factor), false);
        } else {
            sbmp = bmp;
        }

        Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
                radius / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, paint);

        return output;
    }

}

Let's have a simple one-character string 'š' and encode it into a sequence of bytes:

>>> 'š'.encode('utf-8')
b'\xc5\xa1'

For the purpose of this example let's display the sequence of bytes in its binary form:

>>> bin(int(b'\xc5\xa1'.hex(), 16))
'0b1100010110100001'

Now it is generally not possible to decode the information back without knowing how it was encoded. Only if you know that the utf-8 text encoding was used, you can follow the algorithm for decoding utf-8 and acquire the original string:

11000101 10100001
   ^^^^^   ^^^^^^
   00101   100001

You can display the binary number 101100001 back as a string:

>>> chr(int('101100001', 2))
'š'

I deleted any existing popper directories, then ran

npm install --save popper.js angular-popper

$objPHPExcel->getActiveSheet()->getStyle('1:1')->getFont()->setBold(true);

That way you get the complete first row

You can use either:

ActiveCell.Interior.ColorIndex = 28

or

ActiveCell.Interior.Color = RGB(255,0,0)

If you hit git stash when you have changes in the working copy (not in the staging area), git will create a stashed object and pushes onto the stack of stashes (just like you did git checkout -- . but you won't lose changes). Later, you can pop from the top of the stack.

@bcorso has already demonstrated the proof of the complexity analysis. But for the sake of those still learning complexity analysis, I have this to add:

The basis of your original mistake is due to a misinterpretation of the meaning of the statement, "insertion into a heap takes O(log n) time". Insertion into a heap is indeed O(log n), but you have to recognise that n is the size of the heap during the insertion.

In the context of inserting n objects into a heap, the complexity of the ith insertion is O(log n_i) where n_i is the size of the heap as at insertion i. Only the last insertion has a complexity of O (log n).

The profiler data is written to a collection in your DB, not to file. See http://docs.mongodb.org/manual/tutorial/manage-the-database-profiler/

I would recommend using 10gen's MMS service, and feed development profiler data there, where you can filter and sort it in the UI.

$(( ( RANDOM % 10 )  + 1 ))

EDIT. Changed brackets into parenthesis according to the comment. http://web.archive.org/web/20150206070451/http://islandlinux.org/howto/generate-random-numbers-bash-scripting

If you don't mind the dictionary values being tuples, you can use itertuples:

>>> {x[0]: x[1:] for x in df.itertuples(index=False)}
{'p': (1, 3, 2), 'q': (4, 3, 2), 'r': (4, 0, 9)}

I found the answer to the second part of my questions. Yes, a class can implement an interface that is in a different class as long that the interface is declared as public.

If you want to use a gentle approach via a beautiful (for terminal) interactive reporting interface I would suggest using npm-check.

It's less of a hammer and gives you more consequential knowledge of, and control over, your dependency updates.

To give you a taste of what awaits here's a screenshot (scraped from the git page for npm-check):

Hello there: If you need more control on where the link should redirect to, you could use this solution.

Ie. If the user is clicking in the CHECKOUT link, but you want to send him/her to checkout page if its registered(logged in) or registration page if he/she isn't.

You could use JSTL core LIKE:

<!--include the library-->
<%@ taglib prefix="core" uri="http://java.sun.com/jsp/jstl/core" %>

<%--create a var to store link--%>
<core:set var="linkToRedirect">
  <%--test the condition you need--%>
  <core:choose>
    <core:when test="${USER IS REGISTER}">
      checkout.jsp
    </core:when>
    <core:otherwise>
      registration.jsp
    </core:otherwise>
  </core:choose>
</core:set>

EXPLAINING: is the same as...

 //pseudo code
 if(condition == true)
   set linkToRedirect = checkout.jsp
 else
   set linkToRedirect = registration.jsp

THEN: in simple HTML...

<a href="your.domain.com/${linkToRedirect}">CHECKOUT</a>

This is what you are looking for: https://en.wikipedia.org/wiki/XNOR_gate

Here is the logic table:

A B   XOR XNOR
0 0   0   1 
0 1   1   0
1 0   1   0
1 1   0   1

XNOR sometimes is called XAND.

$str = "Hello World!\n\n";
echo chop($str);

output : Hello World!

In general I fully agree with Jason's use of css selector, but in some cases you may not want to change the css, e.g. when using a 3rd party css-template, and rather prefer to add/remove a class on the element.

The following sample shows a simple way of adding/removing a class on ng-mouseenter/mouseleave:

<div ng-app>
  <div 
    class="italic" 
    ng-class="{red: hover}"
    ng-init="hover = false"
    ng-mouseenter="hover = true"
    ng-mouseleave="hover = false">
      Test 1 2 3.
  </div>
</div>

with some styling:

.red {
  background-color: red;
}

.italic {
  font-style: italic;
  color: black;
}

See running example here: jsfiddle sample

Styling on hovering is a view concern. Although the solution above sets a "hover" property in the current scope, the controller does not need to be concerned about this.

Copy & paste example for upserting one table into another, with MERGE:

CREATE GLOBAL TEMPORARY TABLE t1
    (id VARCHAR2(5) ,
     value VARCHAR2(5),
     value2 VARCHAR2(5)
     )
  ON COMMIT DELETE ROWS;

CREATE GLOBAL TEMPORARY TABLE t2
    (id VARCHAR2(5) ,
     value VARCHAR2(5),
     value2 VARCHAR2(5))
  ON COMMIT DELETE ROWS;
ALTER TABLE t2 ADD CONSTRAINT PK_LKP_MIGRATION_INFO PRIMARY KEY (id);

insert into t1 values ('a','1','1');
insert into t1 values ('b','4','5');
insert into t2 values ('b','2','2');
insert into t2 values ('c','3','3');


merge into t2
using t1
on (t1.id = t2.id) 
when matched then 
  update set t2.value = t1.value,
  t2.value2 = t1.value2
when not matched then
  insert (t2.id, t2.value, t2.value2)  
  values(t1.id, t1.value, t1.value2);

select * from t2

Result:

1. b 4 5
2. c 3 3
3. a 1 1

For greater results, you can use listdir() method of the os module along with a generator (a generator is a powerful iterator that keeps its state, remember?). The following code works fine with both versions: Python 2 and Python 3.

Here's a code:

import os

def files(path):  
    for file in os.listdir(path):
        if os.path.isfile(os.path.join(path, file)):
            yield file

for file in files("."):  
    print (file)

The listdir() method returns the list of entries for the given directory. The method os.path.isfile() returns True if the given entry is a file. And the yield operator quits the func but keeps its current state, and it returns only the name of the entry detected as a file. All the above allows us to loop over the generator function.

Go to

C:\drive\xampp(where xampp installed)

simply find php.ini file then in the file search

post_max_size=XXM
upload_max_size=XXM

Change with this code

post_max_size=100M
upload_max_filesize=100M

Don't forget to restart the xampp

What are they?

Nothing special. Just as same as common Java Class Instance.

But those class are Synthetic proxy classes created by java.lang.reflect.Proxy#newProxyInstance

What is there relationship to the JVM? Are they JVM implementation specific?

Introduced in 1.3

http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection

It is a part of Java. so each JVM should support it.

How are they created (Openjdk7 source)?

In short : they are created using JVM ASM tech ( defining javabyte code at runtime )

something using same tech:

• asm( http://asm.ow2.org/ )
• cglib( http://cglib.sourceforge.net/ )

What happens after calling java.lang.reflect.Proxy#newProxyInstance

1. reading the source you can see newProxyInstance call getProxyClass0 to obtain a `Class

   `

2. after lots of cache or sth it calls the magic ProxyGenerator.generateProxyClass which return a byte[]
3. call ClassLoader define class to load the generated $Proxy Class (the classname you have seen)
4. just instance it and ready for use

What happens in magic sun.misc.ProxyGenerator

1. draw a class(bytecode) combining all methods in the interfaces into one

2. each method is build with same bytecode like

   1. get calling Method meth info (stored while generating)
   2. pass info into invocation handler's invoke()
   3. get return value from invocation handler's invoke()
   4. just return it

3. the class(bytecode) represent in form of byte[]

How to draw a class

Thinking your java codes are compiled into bytecodes, just do this at runtime

Talk is cheap show you the code

When you say "doc.open()" it means you can write whatever HTML tag inside the iframe, so you should write all the basic tags for the HTML page and if you want to have a CSS link in your iframe head just write an iframe with CSS link in it. I give you an example:

doc.open();

doc.write('<!DOCTYPE html><html><head><meta charset="utf-8"/><meta http-quiv="Content-Type" content="text/html; charset=utf-8"/><title>Print Frame</title><link rel="stylesheet" type="text/css" href="/css/print.css"/></head><body><table id="' + gridId + 'Printable' + '" class="print" >' + out + '</table></body></html>');

doc.close();

I had to deal with this for my responsive website. I have many different backgrounds for the same elements to deal with different screen widths. My solution is very simple, keep all your images scoped to a css selector, like "zoinked".

The logic:

If user scrolls, then load in styles with background images associated with them. Done!

Here's what I wrote in a library I call "zoinked" I dunno why. It just happened ok?

(function(window, document, undefined) {   var Z = function() {
    this.hasScrolled = false;

    if (window.addEventListener) {
      window.addEventListener("scroll", this, false);
    } else {
      this.load();
    }   };
     Z.prototype.handleEvent = function(e) {
    if ($(window).scrollTop() > 2) {
      this.hasScrolled = true;
      window.removeEventListener("scroll", this);
      this.load();
    }   };
     Z.prototype.load = function() {
    $(document.body).addClass("zoinked");   };
     window.Zoink = Z; 
})(window, document);

For the CSS I'll have all my styles like this:

.zoinked #graphic {background-image: url(large.jpg);}

@media(max-width: 480px) {.zoinked #graphic {background-image: url(small.jpg);}}

My technique with this is to load all the images after the top ones as soon as the user starts to scroll. If you wanted more control you could make the "zoinking" more intelligent.

$(selectedDOM).find();

function looking for all dom objects inside the selected DOM. i.e.

<div id="mainDiv">
    <p>Paragraph 1</p>
    <p>Paragraph 2</p>
    <div id="innerDiv">
         <a href="#">link</a>
         <p>Paragraph 3</p>
    </div>
</div>

here if you write;

$("#mainDiv").find("p");

you will get tree p elements together. On the other side,

$("#mainDiv").children("p");

Function searching in the just children DOMs of the selected DOM object. So, by this code you will get just paragraph 1 and paragraph 2. It is so beneficial to prevent browser doing unnecessary progress.

For those having trouble with these other answers , try OPENQUERY

Example:

 SELECT * FROM OPENQUERY([LinkedServer], 'select * from [DBName].[schema].[tablename]') 

You can use the "extract" or "date_part" functions on intervals as well as timestamps, but I don't think that does what you want. For example, it gives 3 for an interval of '2 days, 3 hours'. However, you can convert an interval to a number of seconds by specifying 'epoch' as the time element you want: extract(epoch from '2 days, 3 hours'::interval) returns 183600 (which you then divide by 3600 to convert seconds to hours).

So, putting this all together, you get basically Michael's answer: extract(epoch from timestamp1 - timestamp2)/3600. Since you don't seem to care about which timestamp precedes which, you probably want to wrap that in abs:

SELECT abs(extract(epoch from timestamp1 - timestamp2)/3600)

You may want to use statement_timestamp(). This give the timestamp when the statement was executed. Whereas NOW() and CURRENT_TIMESTAMP give the timestamp when the transaction started.

For those who is not able to access/install at in environment, can use custom script:

#!/bin/bash
if [ $# -lt 2 ]; then
echo ""
echo "Syntax Error!"
echo "Usage: $0 <shell script> <datetime>"
echo "<datetime> format: %Y%m%d%H%M"
echo "Example: $0 /home/user/scripts/server_backup.sh 202008142350"
echo ""
exit 1
fi

while true; do
  t=$(date +%Y%m%d%H%M);      
  if [ $t -eq $2 ]; then
    /bin/bash $1
    echo DONE $(date);
    break;
  fi;
  sleep 1;
done

Let's name the script as run1time.sh Example could be something like:

nohup bash run1time.sh /path/to/your/script.sh 202008150300 &

Your action method considers model type asList<string>. But, in your view you are waiting for IEnumerable<Standings.Models.Teams>. You can solve this problem with changing the model in your view to List<string>.

But, the best approach would be to return IEnumerable<Standings.Models.Teams> as a model from your action method. Then you haven't to change model type in your view.

But, in my opinion your models are not correctly implemented. I suggest you to change it as:

public class Team
{
    public int Position { get; set; }
    public string HomeGround {get; set;}
    public string NickName {get; set;}
    public int Founded { get; set; }
    public string Name { get; set; }
}

Then you must change your action method as:

public ActionResult Index()
{
    var model = new List<Team>();

    model.Add(new Team { Name = "MU"});
    model.Add(new Team { Name = "Chelsea"});
    ...

    return View(model);
}

And, your view:

@model IEnumerable<Standings.Models.Team>

@{
     ViewBag.Title = "Standings";
}

@foreach (var item in Model)
{
    <div>
        @item.Name
        <hr />
    </div>
}

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between

   BEGIN
   SELECT MONTH(CURDATE()) INTO @curmonth;
   SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
   SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
   SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
   SELECT DAY(@checkweekday) INTO @checkday;
   SET @daycount = 0;
   SET @workdays = 0;

     WHILE(@daycount < @totaldays) DO
       IF (WEEKDAY(@checkweekday) < 5) THEN
         SET @workdays = @workdays+1;
       END IF;
       SET @daycount = @daycount+1;
       SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
     END WHILE;
   END

Just for others:

If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query

    delimiter ;;
    drop procedure if exists test2;;
    create procedure test2()
    begin
    select ‘Hello World’;
    end
    ;;

Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.

The first_day function you need is: How to get first day of every corresponding month in mysql?

Showing the Procedure is working Simply add the following line below END WHILE and above END

    SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;

Then use the following code in the SQL Query Window.

    call test2 /* or whatever you changed the name of the stored procedure to */

NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

Just simply the css style using white-space:nowrap works very well to avoid text wrapping in cells. And ofcourse you can use the text-overflow:ellipsis and overflow:hidden for truncating text with ellipsis effect.

<td style="white-space:nowrap">Cell Value</td>

Make's substitutions feature is nice and helped me to write

%.i: src/%.c $(INCLUDE)
        gcc -E $(CPPFLAGS) $(INCLUDE:%=-I %) $< > $@

You might find this useful, because it asks make to check for changes in include folders too

Just make round(x-0.5) this will always return the next rounded down Integer value of your Float. You can also easily round up by do round(x+0.5)

Apparently, not only the absolute speeds but also the speed order (as reported by user1579844) are machine dependent; here's what I found:

a=np.empty(1e4); a.fill(5) is fastest;

In descending speed order:

timeit a=np.empty(1e4); a.fill(5) 
# 100000 loops, best of 3: 10.2 us per loop
timeit a=np.empty(1e4); a[:]=5
# 100000 loops, best of 3: 16.9 us per loop
timeit a=np.ones(1e4)*5
# 100000 loops, best of 3: 32.2 us per loop
timeit a=np.tile(5,[1e4])
# 10000 loops, best of 3: 90.9 us per loop
timeit a=np.repeat(5,(1e4))
# 10000 loops, best of 3: 98.3 us per loop
timeit a=np.array([5]*int(1e4))
# 1000 loops, best of 3: 1.69 ms per loop (slowest BY FAR!)

So, try and find out, and use what's fastest on your platform.

If you have used Powershell commands to set the Proxy on windows machine doing the below helped me.

To unset the proxy use: 1. Open powershell 2. Enter the following:

[Environment]::SetEnvironmentVariable(“HTTP_PROXY”, $null, [EnvironmentVariableTarget]::Machine)
[Environment]::SetEnvironmentVariable(“HTTPS_PROXY”, $null, [EnvironmentVariableTarget]::Machine)

To set the proxy again use: 1. Open powershell 2. Enter the following:

[Environment]::SetEnvironmentVariable(“HTTP_PROXY”, “http://yourproxy.com:yourportnumber”, [EnvironmentVariableTarget]::Machine)
[Environment]::SetEnvironmentVariable(“HTTPS_PROXY”, “http://yourproxy.com:yourportnumber”, [EnvironmentVariableTarget]::Machine)

For additional:

For vertical orientation, don't forget set height to 0dp

android:layout_height="0dp"

For horizontal orientation, don't forget set width to 0dp

android:layout_width="0dp"

I suggest much better solution. Task in my case: add http://google.com/ path before each record and import multiple fields.

CSV single field value (all images just have filenames, separate by |):
"123.jpg|345.jpg|567.jpg"

Tamper 1st plugin: find and replace by REGEXP: pattern: /([a-zA-Z0-9]*)./ replacement: http://google.com/$1

Tamper 2nd plugin: explode setting: explode by |

In this case you don't need any additinal fields mappings and can use 1 field in CSV

Adding import android.support.v7.widget.Toolbar to the import list resolve this issue.

Then add the toolbar widget layout file:

<android.support.v7.widget.Toolbar
    android:id="@+id/list_toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    android:theme="?attr/actionBarTheme"
    />

In onCreate method of java code

//call to

Tootbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar);

Probably the best way to do it is using rake to write the tasks you need and the just execute it via command line.

You can see a very helpful video at railscasts

None?

I mean, other than removing it from the layout entirely with display: none, I'm pretty sure that's it.

Are you facing a particular situation in which position: absolute is not a viable solution?

This works:

<select name="foo" id="foo">
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>
</select>
<input type="button" id="button" value="Button" />

$('#button').click(function() {
    alert($('#foo option:selected').text());
    alert($('#foo option:selected').val());
});

You can try something like this. Here on click of image button I toggle the imageview.

holder.imgitem.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            if(!onclick){
            mSparseBooleanArray.put((Integer) view.getTag(), true);
            holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_delete_overlay_com);
            onclick=true;}
            else if(onclick)
            {
                 mSparseBooleanArray.put((Integer) view.getTag(), false);
                  holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_selection_com);

            onclick=false;
            }
        }
    });

inplace of connection.connect(); use -

if(!connection._connectCalled ) 
{
connection.connect();
}

if it is already called then connection._connectCalled =true,
& it will not execute connection.connect();

note - don't use connection.end();

This solution worked well for me: http://www.apachefriends.org/f/viewtopic.php?f=17&t=50902&p=196185#p196185

Edit /opt/lampp/etc/extra/httpd-xampp.conf and adding Require all granted line at bottom of block <Directory "/opt/lampp/phpmyadmin"> to have the following code:

You can add your attribute on callback function ({key} , speed.callback, like is

$('.usercontent').animate( {
    backgroundColor:'#ddd',
},1000,function () {
    $(this).css("backgroundColor","red")
});

If you want to extract the first number out of the input string, you can do-

public static String extractNumber(final String str) {                
    
    if(str == null || str.isEmpty()) return "";
    
    StringBuilder sb = new StringBuilder();
    boolean found = false;
    for(char c : str.toCharArray()){
        if(Character.isDigit(c)){
            sb.append(c);
            found = true;
        } else if(found){
            // If we already found a digit before and this char is not a digit, stop looping
            break;                
        }
    }
    
    return sb.toString();
}

Examples:

For input "123abc", the method above will return 123.

For "abc1000def", 1000.

For "555abc45", 555.

For "abc", will return an empty string.

To get all indices that matches 'Smith'

>>> df[df['LastName'] == 'Smith'].index
Int64Index([1], dtype='int64')

or as a numpy array

>>> df[df['LastName'] == 'Smith'].index.to_numpy()  # .values on older versions
array([1])

or if there is only one and you want the integer, you can subset

>>> df[df['LastName'] == 'Smith'].index[0]
1

You could use the same boolean expressions with .loc, but it is not needed unless you also want to select a certain column, which is redundant when you only want the row number/index.

Cursors may also be used, although it is inefficient. The following stackoverflow post discusses the usage of cursors :

oh boy, this got resolved, I just had to name my Installed JRE appropriately. I had only the jdk installed and eclipse had taken the default jdk name, i renamed it to JavaSE-1.6 and voila it worked, though i had to redo everthing from the scratch.

When using the for loop, the value of s is a Map.Entry element, meaning that you can get the key from s.key and the value from s.value

You can run below commands. I believe this is what you want!

Try skipping the p tag or replace it with a h3 tag or similar. Replace:

It worked for me, I don't know why, but it seems the p tag is somehow not fully compatible with some versions of Bootstrap.

For SQL Server 2008

SELECT email,
       CASE
         WHEN EXISTS(SELECT *
                     FROM   Users U
                     WHERE  E.email = U.email) THEN 'Exist'
         ELSE 'Not Exist'
       END AS [Status]
FROM   (VALUES('email1'),
              ('email2'),
              ('email3'),
              ('email4')) E(email)  

For previous versions you can do something similar with a derived table UNION ALL-ing the constants.

/*The SELECT list is the same as previously*/
FROM (
SELECT 'email1' UNION ALL
SELECT 'email2' UNION ALL
SELECT 'email3' UNION ALL
SELECT 'email4'
)  E(email)

Or if you want just the non-existing ones (as implied by the title) rather than the exact resultset given in the question, you can simply do this

SELECT email
FROM   (VALUES('email1'),
              ('email2'),
              ('email3'),
              ('email4')) E(email)  
EXCEPT
SELECT email
FROM Users

Alternatively, if you want to solely obtain the current directory of the current NodeJS script, you could try something simple like this. Note that this will not work in the Node CLI itself:

var fs = require('fs'),
    path = require('path');

var dirString = path.dirname(fs.realpathSync(__filename));

// output example: "/Users/jb/workspace/abtest"
console.log('directory to start walking...', dirString);

Use array_count_values() function . Check this link http://php.net/manual/en/function.array-count-values.php

is very fast but very rarely inaccurate.

I faced a similar issue, you can refer to my answer here.

But since links die too often, I'm going to leave a little part of the answer that might help:

For people still having this error even if their git is installed and android studio is pointing to its path, go to Settings -> Version Control -> Git and delete everything inside the text box with the label Path to Git executable, your android studio or what ever JetBrains product you're using, will auto-detect it.

You could use AJAX to call this controller action. For example if you are using jQuery you might use the $.ajax() method:

<script type="text/javascript">
    $.ajax({
        url: '@Url.Action("NameOfYourAction")',
        type: 'GET',
        cache: false,
        success: function(result) {
            // you could use the result.values dictionary here
        }
    });
</script>

I am trying to understand what Python's descriptors are and what they can be useful for.

Descriptors are class attributes (like properties or methods) with any of the following special methods:

• __get__ (non-data descriptor method, for example on a method/function)
• __set__ (data descriptor method, for example on a property instance)
• __delete__ (data descriptor method)

These descriptor objects can be used as attributes on other object class definitions. (That is, they live in the __dict__ of the class object.)

Descriptor objects can be used to programmatically manage the results of a dotted lookup (e.g. foo.descriptor) in a normal expression, an assignment, and even a deletion.

Functions/methods, bound methods, property, classmethod, and staticmethod all use these special methods to control how they are accessed via the dotted lookup.

A data descriptor, like property, can allow for lazy evaluation of attributes based on a simpler state of the object, allowing instances to use less memory than if you precomputed each possible attribute.

Another data descriptor, a member_descriptor, created by __slots__, allow memory savings by allowing the class to store data in a mutable tuple-like datastructure instead of the more flexible but space-consuming __dict__.

Non-data descriptors, usually instance, class, and static methods, get their implicit first arguments (usually named cls and self, respectively) from their non-data descriptor method, __get__.

Most users of Python need to learn only the simple usage, and have no need to learn or understand the implementation of descriptors further.

In Depth: What Are Descriptors?

A descriptor is an object with any of the following methods (__get__, __set__, or __delete__), intended to be used via dotted-lookup as if it were a typical attribute of an instance. For an owner-object, obj_instance, with a descriptor object:

• obj_instance.descriptor invokes
  descriptor.__get__(self, obj_instance, owner_class) returning a value
  This is how all methods and the get on a property work.

• obj_instance.descriptor = value invokes
  descriptor.__set__(self, obj_instance, value) returning None
  This is how the setter on a property works.

• del obj_instance.descriptor invokes
  descriptor.__delete__(self, obj_instance) returning None
  This is how the deleter on a property works.

obj_instance is the instance whose class contains the descriptor object's instance. self is the instance of the descriptor (probably just one for the class of the obj_instance)

To define this with code, an object is a descriptor if the set of its attributes intersects with any of the required attributes:

def has_descriptor_attrs(obj):
    return set(['__get__', '__set__', '__delete__']).intersection(dir(obj))

def is_descriptor(obj):
    """obj can be instance of descriptor or the descriptor class"""
    return bool(has_descriptor_attrs(obj))

A Data Descriptor has a __set__ and/or __delete__.
A Non-Data-Descriptor has neither __set__ nor __delete__.

def has_data_descriptor_attrs(obj):
    return set(['__set__', '__delete__']) & set(dir(obj))

def is_data_descriptor(obj):
    return bool(has_data_descriptor_attrs(obj))

Builtin Descriptor Object Examples:

• classmethod
• staticmethod
• property
• functions in general

Non-Data Descriptors

We can see that classmethod and staticmethod are Non-Data-Descriptors:

>>> is_descriptor(classmethod), is_data_descriptor(classmethod)
(True, False)
>>> is_descriptor(staticmethod), is_data_descriptor(staticmethod)
(True, False)

Both only have the __get__ method:

>>> has_descriptor_attrs(classmethod), has_descriptor_attrs(staticmethod)
(set(['__get__']), set(['__get__']))

Note that all functions are also Non-Data-Descriptors:

>>> def foo(): pass
... 
>>> is_descriptor(foo), is_data_descriptor(foo)
(True, False)

Data Descriptor, property

However, property is a Data-Descriptor:

>>> is_data_descriptor(property)
True
>>> has_descriptor_attrs(property)
set(['__set__', '__get__', '__delete__'])

Dotted Lookup Order

These are important distinctions, as they affect the lookup order for a dotted lookup.

obj_instance.attribute

1. First the above looks to see if the attribute is a Data-Descriptor on the class of the instance,
2. If not, it looks to see if the attribute is in the obj_instance's __dict__, then
3. it finally falls back to a Non-Data-Descriptor.

The consequence of this lookup order is that Non-Data-Descriptors like functions/methods can be overridden by instances.

Recap and Next Steps

We have learned that descriptors are objects with any of __get__, __set__, or __delete__. These descriptor objects can be used as attributes on other object class definitions. Now we will look at how they are used, using your code as an example.

Analysis of Code from the Question

Here's your code, followed by your questions and answers to each:

class Celsius(object):
    def __init__(self, value=0.0):
        self.value = float(value)
    def __get__(self, instance, owner):
        return self.value
    def __set__(self, instance, value):
        self.value = float(value)

class Temperature(object):
    celsius = Celsius()

1. Why do I need the descriptor class?

Your descriptor ensures you always have a float for this class attribute of Temperature, and that you can't use del to delete the attribute:

>>> t1 = Temperature()
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

Otherwise, your descriptors ignore the owner-class and instances of the owner, instead, storing state in the descriptor. You could just as easily share state across all instances with a simple class attribute (so long as you always set it as a float to the class and never delete it, or are comfortable with users of your code doing so):

class Temperature(object):
    celsius = 0.0

This gets you exactly the same behavior as your example (see response to question 3 below), but uses a Pythons builtin (property), and would be considered more idiomatic:

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

2. What is instance and owner here? (in get). What is the purpose of these parameters?

instance is the instance of the owner that is calling the descriptor. The owner is the class in which the descriptor object is used to manage access to the data point. See the descriptions of the special methods that define descriptors next to the first paragraph of this answer for more descriptive variable names.

3. How would I call/use this example?

Here's a demonstration:

>>> t1 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1
>>> 
>>> t1.celsius
1.0
>>> t2 = Temperature()
>>> t2.celsius
1.0

You can't delete the attribute:

>>> del t2.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

And you can't assign a variable that can't be converted to a float:

>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 7, in __set__
ValueError: invalid literal for float(): 0x02

Otherwise, what you have here is a global state for all instances, that is managed by assigning to any instance.

The expected way that most experienced Python programmers would accomplish this outcome would be to use the property decorator, which makes use of the same descriptors under the hood, but brings the behavior into the implementation of the owner class (again, as defined above):

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

Which has the exact same expected behavior of the original piece of code:

>>> t1 = Temperature()
>>> t2 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1.0
>>> t2.celsius
1.0
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: can't delete attribute
>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 8, in celsius
ValueError: invalid literal for float(): 0x02

Conclusion

We've covered the attributes that define descriptors, the difference between data- and non-data-descriptors, builtin objects that use them, and specific questions about use.

So again, how would you use the question's example? I hope you wouldn't. I hope you would start with my first suggestion (a simple class attribute) and move on to the second suggestion (the property decorator) if you feel it is necessary.

There is no such thing as importing in MS SQL. I understand what you mean. It is so simple. Whenever you get/have a something.SQL file, you should just double click and it will directly open in your MS SQL Studio.

a complete circle in radians is 2*pi. A complete circle in degrees is 360. To go from degrees to radians, it's (d/360) * 2*pi, or d*pi/180.

In general, the best way to find any file in any arbitrary location is to start a terminal window and type in the classic Unix command "find":

find / -name index.html -print

Since the file you're looking for is the root file in the root directory of your web server, it's probably easier to find your web server's document root. For example, look under:

/var/www/*

Or type:

find /var/www -name index.html -print

I think you want a mapValues function (to map a function over the values of an object), which is easy enough to implement yourself:

mapValues = function(obj, f) {
  var k, result, v;
  result = {};
  for (k in obj) {
    v = obj[k];
    result[k] = f(v);
  }
  return result;
};

The simplest way is to save the original value using data() when the element gets focus. Here is a really basic example:

JSFiddle: http://jsfiddle.net/TrueBlueAussie/e4ovx435/

$('input').on('focusin', function(){
    console.log("Saving value " + $(this).val());
    $(this).data('val', $(this).val());
});

$('input').on('change', function(){
    var prev = $(this).data('val');
    var current = $(this).val();
    console.log("Prev value " + prev);
    console.log("New value " + current);
});

Better to use Delegated Event Handlers

Note: it is generally more efficient to use a delegated event handler when there can be multiple matching elements. This way only a single handler is added (smaller overhead and faster initialisation) and any speed difference at event time is negligible.

Here is the same example using delegated events connected to document:

$(document).on('focusin', 'input', function(){
    console.log("Saving value " + $(this).val());
    $(this).data('val', $(this).val());
}).on('change','input', function(){
    var prev = $(this).data('val');
    var current = $(this).val();
    console.log("Prev value " + prev);
    console.log("New value " + current);
});

JsFiddle: http://jsfiddle.net/TrueBlueAussie/e4ovx435/65/

Delegated events work by listening for an event (focusin, change etc) on an ancestor element (document* in this case), then applying the jQuery filter (input) to only the elements in the bubble chain then applying the function to only those matching elements that caused the event.

*Note: A a general rule, use document as the default for delegated events and not body. body has a bug, to do with styling, that can cause it to not get bubbled mouse events. Also document always exists so you can attach to it outside of a DOM ready handler :)

Here's how to create a copy of a DataFrame excluding a list of columns:

df = pd.DataFrame(np.random.randn(100, 4), columns=list('ABCD'))
df2 = df.drop(['B', 'D'], axis=1)

But be careful! You mention views in your question, suggesting that if you changed df, you'd want df2 to change too. (Like a view would in a database.)

This method doesn't achieve that:

>>> df.loc[0, 'A'] = 999 # Change the first value in df
>>> df.head(1)
     A         B         C         D
0  999 -0.742688 -1.980673 -0.920133
>>> df2.head(1) # df2 is unchanged. It's not a view, it's a copy!
          A         C
0  0.251262 -1.980673

Note also that this is also true of @piggybox's method. (Although that method is nice and slick and Pythonic. I'm not doing it down!!)

For more on views vs. copies see this SO answer and this part of the Pandas docs which that answer refers to.

To get a fully qualified name for a machine, we must first get the local hostname, and then lookup the canonical name.

The easiest way to do this is by first getting the local hostname using uname() or gethostname() and then performing a lookup with gethostbyname() and looking at the h_name member of the struct it returns. If you are using ANSI c, you must use uname() instead of gethostname().

Example:

char hostname[1024];
hostname[1023] = '\0';
gethostname(hostname, 1023);
printf("Hostname: %s\n", hostname);
struct hostent* h;
h = gethostbyname(hostname);
printf("h_name: %s\n", h->h_name);

Unfortunately, gethostbyname() is deprecated in the current POSIX specification, as it doesn't play well with IPv6. A more modern version of this code would use getaddrinfo().

Example:

struct addrinfo hints, *info, *p;
int gai_result;

char hostname[1024];
hostname[1023] = '\0';
gethostname(hostname, 1023);

memset(&hints, 0, sizeof hints);
hints.ai_family = AF_UNSPEC; /*either IPV4 or IPV6*/
hints.ai_socktype = SOCK_STREAM;
hints.ai_flags = AI_CANONNAME;

if ((gai_result = getaddrinfo(hostname, "http", &hints, &info)) != 0) {
    fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(gai_result));
    exit(1);
}

for(p = info; p != NULL; p = p->ai_next) {
    printf("hostname: %s\n", p->ai_canonname);
}

freeaddrinfo(info);

Of course, this will only work if the machine has a FQDN to give - if not, the result of the getaddrinfo() ends up being the same as the unqualified hostname.

Working on android studio: 3.6.3 and gradle version:

classpath 'com.android.tools.build:gradle:3.6.3'

You can use Manifold's @Jailbreak for direct, type-safe Java reflection:

@Jailbreak Foo foo = new Foo();
foo.callMe();

public class Foo {
    private void callMe();
}

@Jailbreak unlocks the foo local variable in the compiler for direct access to all the members in Foo's hierarchy.

Similarly you can use the jailbreak() extension method for one-off use:

foo.jailbreak().callMe();

Through the jailbreak() method you can access any member in Foo's hierarchy.

In both cases the compiler resolves the method call for you type-safely, as if a public method, while Manifold generates efficient reflection code for you under the hood.

Alternatively, if the type is not known statically, you can use Structural Typing to define an interface a type can satisfy without having to declare its implementation. This strategy maintains type-safety and avoids performance and identity issues associated with reflection and proxy code.

michal.kreuzman nice one I will have to say. It was useful.

However, the above works only for single digits: if you are going to use more than one digit, the structure is going to get misplaced since you are using spaces and not tabs.

As for my later codes I needed more digits than only 2, so I made a program myself.

It has some bugs now, again right now I am feeling lazy to correct them but it prints very beautifully and the nodes can take a larger number of digits.

The tree is not going to be as the question mentions but it is 270 degrees rotated :)

public static void printBinaryTree(TreeNode root, int level){
    if(root==null)
         return;
    printBinaryTree(root.right, level+1);
    if(level!=0){
        for(int i=0;i<level-1;i++)
            System.out.print("|\t");
        System.out.println("|-------"+root.val);
    }
    else
        System.out.println(root.val);
    printBinaryTree(root.left, level+1);
}    

Place this function with your own specified TreeNode and keep the level initially 0, and enjoy!

Here are some of the sample outputs:

|       |       |-------11
|       |-------10
|       |       |-------9

Only problem is with the extending branches; I will try to solve the problem as soon as possible but till then you can use it too.

Use this script instead:

@taskkill/f /im test.exe >nul 2>&1
@pause

What the 2>&1 part actually does, is that it redirects the stderr output to stdout. I will explain it better below:

@taskkill/f /im test.exe >nul 2>&1

Kill the task "test.exe". Redirect stderr to stdout. Then, redirect stdout to nul.

@pause

Show the pause message Press any key to continue . . . until someone presses a key.

NOTE: The @ symbol is hiding the prompt for each command. You can save up to 8 bytes this way.

The shortest version of your script could be:
@taskkill/f /im test.exe >nul 2>&1&pause
The & character is used for redirection the first time, and for separating the commands the second time.
An @ character is not needed twice in a line. This code is just 40 bytes, despite the one you've posted being 49 bytes! I actually saved 9 bytes. For a cleaner code look above.

Watch again:

char dest[5];
char src[5] = "test";

printf("String: %s\n", do_something(dest, src));

Focus on this line:

printf("String: %s\n", do_something(dest, src));

You can clearly see that the do_something function is not declared!

If you look a little further,

printf("String: %s\n", do_something(dest, src));

char *do_something(char *dest, const char *src)
{
return dest;
}

you will see that you declare the function after you use it.

You will need to modify this part with this code:

char *do_something(char *dest, const char *src)
{
return dest;
}

printf("String: %s\n", do_something(dest, src));

Cheers ;)

I had this due to one project referencing another.

1. Remove reference from project A to project B
2. Try running stuff, it will break
3. Re-add reference
4. Clean/Clean and build
5. Back in business

you can try this

Renee's answer is well explained. Addition to the answer with an example:

Node does a lot of things to your file and one of the important is WRAPPING your file. Inside nodejs source code "module.exports" is returned. Lets take a step back and understand the wrapper. Suppose you have

greet.js

var greet = function () {
   console.log('Hello World');
};

module.exports = greet;

the above code is wrapped as IIFE(Immediately Invoked Function Expression) inside nodejs source code as follows:

(function (exports, require, module, __filename, __dirname) { //add by node

      var greet = function () {
         console.log('Hello World');
      };

      module.exports = greet;

}).apply();                                                  //add by node

return module.exports;                                      //add by node

and the above function is invoked (.apply()) and returned module.exports. At this time module.exports and exports pointing to the same reference.

Now, imagine you re-write greet.js as

exports = function () {
   console.log('Hello World');
};
console.log(exports);
console.log(module.exports);

the output will be

[Function]
{}

the reason is : module.exports is an empty object. We did not set anything to module.exports rather we set exports = function()..... in new greet.js. So, module.exports is empty.

Technically exports and module.exports should point to same reference(thats correct!!). But we use "=" when assigning function().... to exports, which creates another object in the memory. So, module.exports and exports produce different results. When it comes to exports we can't override it.

Now, imagine you re-write (this is called Mutation) greet.js (referring to Renee answer) as

exports.a = function() {
    console.log("Hello");
}

console.log(exports);
console.log(module.exports);

the output will be

{ a: [Function] }
{ a: [Function] }

As you can see module.exports and exports are pointing to same reference which is a function. If you set a property on exports then it will be set on module.exports because in JS, objects are pass by reference.

Conclusion is always use module.exports to avoid confusion. Hope this helps. Happy coding :)

you can simply use,

var className = $('#id').attr('class');

You may also use element.insertAdjacentHTML('beforeend', data);

These issue arise generally due to mismatch between @ngx-translate/core version and Angular .Before installing check compatible version of corresponding ngx_trnalsate/Core, @ngx-translate/http-loader and Angular at https://www.npmjs.com/package/@ngx-translate/core

Eg: For Angular 6.X versions,

npm install @ngx-translate/core@10 @ngx-translate/http-loader@3 rxjs --save

Like as above, follow below command and rest of code part is common for all versions(Note: Version can obtain from( https://www.npmjs.com/package/@ngx-translate/core)

npm install @ngx-translate/core@version @ngx-translate/http-loader@version rxjs --save

You can rename classes or any file by hitting F2 on the filename in Eclipse. It will ask you if you want to update references. It's really as easy as that :)

First you should use print_r($_FILES) to debug, and see what it contains. :

your uploads.php would look like:

//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];


//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
    // Connects to your Database
    mysql_connect("localhost", "root", "") or die(mysql_error()) ;
    mysql_select_db("altabotanikk") or die(mysql_error()) ;

    //Writes the information to the database
    mysql_query("INSERT INTO picture (Filename,Description)
    VALUES ('$Filename', '$Description')") ;
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}

EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php

Here's a function that accurately provides the number of months between 2 dates.
The default behavior only counts whole months, e.g. 3 months and 1 day will result in a difference of 3 months. You can prevent this by setting the roundUpFractionalMonths param as true, so a 3 month and 1 day difference will be returned as 4 months.

The accepted answer above (T.J. Crowder's answer) isn't accurate, it returns wrong values sometimes.

For example, monthDiff(new Date('Jul 01, 2015'), new Date('Aug 05, 2015')) returns 0 which is obviously wrong. The correct difference is either 1 whole month or 2 months rounded-up.

Here's the function I wrote:

function getMonthsBetween(date1,date2,roundUpFractionalMonths)
{
    //Months will be calculated between start and end dates.
    //Make sure start date is less than end date.
    //But remember if the difference should be negative.
    var startDate=date1;
    var endDate=date2;
    var inverse=false;
    if(date1>date2)
    {
        startDate=date2;
        endDate=date1;
        inverse=true;
    }

    //Calculate the differences between the start and end dates
    var yearsDifference=endDate.getFullYear()-startDate.getFullYear();
    var monthsDifference=endDate.getMonth()-startDate.getMonth();
    var daysDifference=endDate.getDate()-startDate.getDate();

    var monthCorrection=0;
    //If roundUpFractionalMonths is true, check if an extra month needs to be added from rounding up.
    //The difference is done by ceiling (round up), e.g. 3 months and 1 day will be 4 months.
    if(roundUpFractionalMonths===true && daysDifference>0)
    {
        monthCorrection=1;
    }
    //If the day difference between the 2 months is negative, the last month is not a whole month.
    else if(roundUpFractionalMonths!==true && daysDifference<0)
    {
        monthCorrection=-1;
    }

    return (inverse?-1:1)*(yearsDifference*12+monthsDifference+monthCorrection);
};

It should be like this

$(this).text($(this).text().replace('N/A, ', ''))

In one line of code as below :

<p> cursor on text field shows text .if not password will be shown</p>_x000D_
<input type="password" name="txt_password" onmouseover="this.type='text'"_x000D_
       onmouseout="this.type='password'" placeholder="password" />

Overriding depends on having an instance of a class. The point of polymorphism is that you can subclass a class and the objects implementing those subclasses will have different behaviors for the same methods defined in the superclass (and overridden in the subclasses). A static method is not associated with any instance of a class so the concept is not applicable.

There were two considerations driving Java's design that impacted this. One was a concern with performance: there had been a lot of criticism of Smalltalk about it being too slow (garbage collection and polymorphic calls being part of that) and Java's creators were determined to avoid that. Another was the decision that the target audience for Java was C++ developers. Making static methods work the way they do had the benefit of familiarity for C++ programmers and was also very fast, because there's no need to wait until runtime to figure out which method to call.

You can use .on() to bind a function to multiple events:

$('#element').on('keyup keypress blur change', function(e) {
    // e.type is the type of event fired
});

Or just pass the function as the parameter to normal event functions:

var myFunction = function() {
   ...
}

$('#element')
    .keyup(myFunction)
    .keypress(myFunction)
    .blur(myFunction)
    .change(myFunction)

Separate these functions from controllers and put them into model file. Then include the model file in your controller.

You can run a container setting a shared directory (-v volume), and then run bash in that container. After this, you can interactively use mysql-client to execute the .sql file, from inside the container. obs: /my-host-dir/shared-dir is the .sql location in the host system.

docker run --detach --name=test-mysql -p host-port:container-port  --env="MYSQL_ROOT_PASSWORD=my-root-pswd" -v /my-host-dir/shared-dir:/container-dir mysql:latest


docker exec -it test-mysql bash

Inside the container...

mysql -p < /container-dir/file.sql 

Custom parameters:

• test-mysql (container name)
• host-port and container-port
• my-root-pswd (mysql root password)
• /my-host-dir/shared-dir and /container-dir (the host directory that will be mounted in the container, and the container location of the shared directory)

3 options, same result:

1. All steps:

  $ rake db:drop           # deletes the database for the current env
  $ rake db:create         # creates the database for the current env
  $ rake db:schema:load    # loads the schema already generated from schema.rb / erases data
  $ rake db:seed           # seed with initial data

2. Reset:

  $ rake db:reset          # drop / schema:load / seed

3. Migrate:reset:

  $ rake db:migrate:reset  # drop / create / migrate
  $ rake db:seed

Notes:

• If schema:load is used is faster than doing all migrations, but same result.
• All data will be lost.
• You can run multiple rakes in one line.
• Works with rails 3.

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

For Linux and macOS this can be done in one line, using parameter expansion to change the filename extension of the output file:

for i in *.avi; do ffmpeg -i "$i" "${i%.*}.mp4"; done

Try This, It's working for me .

Single line of code

[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:[[NSBundle mainBundle] bundleIdentifier]];

You don't need jQuery for this, as simple javascript will suffice:

alert(document.domain);

See it in action:

console.log("Output;");  
console.log(location.hostname);
console.log(document.domain);
alert(window.location.hostname)

console.log("document.URL : "+document.URL);
console.log("document.location.href : "+document.location.href);
console.log("document.location.origin : "+document.location.origin);
console.log("document.location.hostname : "+document.location.hostname);
console.log("document.location.host : "+document.location.host);
console.log("document.location.pathname : "+document.location.pathname);

for more details click here window.location

just append "http://" before domain name to get appropriate result.

For all the given solution, when you try this in a modern browser (like FF), and you have set the correct model

// Model
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]
public DateTime Start { get; set; }

// View
<div class="form-group">
    @Html.LabelFor(model => model.Start, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.Start, "{0:dd-MM-yyyy}", new { htmlAttributes = new { @class = "form-control"} })
    </div>
</div>

mvc(5) wil render (the type of the input is set to date based on your date settings in your model!)

<div class="col-md-10">
<input class="form-control text-box single-line" data-val="true" data-val-date="The field Start must be a date." data-val-required="The Start field is required." id="Start" name="Start" value="01-05-2018" type="date">
        <span class="field-validation-valid text-danger" data-valmsg-for="Start" data-valmsg-replace="true"></span>
</div>

And the browser will show

To fix this you need to change the type to text instead of date (also if you want to use your custom calender)

@Html.EditorFor(model => model.Start, "{0:dd-MM-yyyy}", new { htmlAttributes = new { @class = "form-control", @type = "text" } })

The correct syntax to do this on your relations is:

Event::whereHas('participants', function ($query) {
    return $query->where('IDUser', '=', 1);
})->get();

Good question. I'm using the Bootstrap Dropdown Menu, and needed to execute an event when a Bootstrap Dropdown was hidden. When the dropdown is opened, the containing div with a class name of "button-group" adds a class of "open"; and the button itself has an "aria-expanded" attribute set to true. When the dropdown is closed, that class of "open" is removed from the containing div, and aria-expanded is switched from true to false.

That led me to this question, of how to detect the class change.

With Bootstrap, there are "Dropdown Events" that can be detected. Look for "Dropdown Events" at this link. http://www.w3schools.com/bootstrap/bootstrap_ref_js_dropdown.asp

Here is a quick-and-dirty example of using this event on a Bootstrap Dropdown.

$(document).on('hidden.bs.dropdown', function(event) {
    console.log('closed');
});

Now I realize this is more specific than the general question that's being asked. But I imagine other developers trying to detect an open or closed event with a Bootstrap Dropdown will find this helpful. Like me, they may initially go down the path of simply trying to detect an element class change (which apparently isn't so simple). Thanks.

How about

with open(csv_input_path + file, 'r') as ft:
    header = ft.readline() # read only first line; returns string
    header_list = header.split(',') # returns list

I am assuming your input file is CSV format. If using pandas, it takes more time if the file is big size because it loads the entire data as the dataset.

UPDATE: Since I wrote this, the input event has gotten a decent level of support. It is still not 100% in IE9, so you will have to wait a bit until IE9 is fully phased out. In light of my answer to this question, however, input is more than a decent replacement for the method I've presented, so I recommend switching.

Use keyup event

var inp = document.getElementById('myinput');_x000D_
var chars = document.getElementById('chars');_x000D_
inp.onkeyup = function() {_x000D_
  chars.innerHTML = inp.value.length;_x000D_
}

<input id="myinput"><span id="chars">0</span>

EDIT:

Just a note for those that suggest keydown. That won't work. The keydown fires before character is added to the input box or textarea, so the length of the value would be wrong (one step behind). Therefore, the only solution that works is keyup, which fires after the character is added.

<h2>JavaScript Email Validation</h2>

<input id="textEmail">

        var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;

        if (reg.test(textEmail.value) == false) 
        {
        document.getElementById("demo").style.color = "red";
            document.getElementById("demo").innerHTML ="Invalid EMail ->"+ email;
            alert('Invalid Email Address ->'+email);
            return false;
        } else{

        document.getElementById("demo").innerHTML ="Valid Email ->"+email;
        }

   return true;
}
</script>

The code I ended up using was,

clearReviewFileSel: function() {
  var oldInput = document.getElementById('edit-file-upload-review-pdf') ;
  var newInput = document.createElement('input');
  newInput.id    = oldInput.id ;
  newInput.type  = oldInput.type ;
  newInput.name  = oldInput.name ;
  newInput.size  = oldInput.size ;
  newInput.class  = oldInput.class ;
  oldInput.parentNode.replaceChild(newInput, oldInput); 
}

Thanks everyone for the suggestions and pointers!

The simplest and probably best way is to try adding the files manually (generally this takes precedence over .gitignore-style rules):

git add /path/to/module

You may even want the -N intent to add flag, to suggest you will add them, but not immediately. I often do this for new files I’m not ready to stage yet.

This a copy of an answer posted on what could easily be a duplicate QA. I am reposting it here for increased visibility—I find it easier not to have a mess of gitignore rules.

After trying these solutions I still wasn't satisfied but I found a solution in this article and it works in Chrome, Firefox, Opera, Safari, IE8+

}

I also faced the same problem and

remove.packages(c("ggplot2", "data.table"))
install.packages('Rcpp', dependencies = TRUE)
install.packages('ggplot2', dependencies = TRUE)

these commands did not work for me. What I found was that it was showing a warning message that it could not move temporary installation C:\Users\User_name\Documents\R\win-library\3.3\abcd1234\Rcpp to C:\Users\User_name\Documents\R\win-library\3.3\Rcpp.

I downloaded the Rcpp zip file from the link given and unziped it and copied it inside C:\Users\User_name\Documents\R\win-library\3.3 and then

library(Rcpp)
library(ggplot2) 

worked. I did not have to uninstall R. Hope this helps.

You can compile with either Cygwin's g++ or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll (and others) PATH to the system Windows PATH, before any cygwin style paths.

Thus add: ;C:\cygwin64\bin to the end of your Windows system PATH variable.

Also, to compile for use in CMD or PowerShell, you may need to use:

x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe

_{(This invokes the cross-compiler, if installed.)}

For anyone coming to this latterly, I was having this problem over a Windows network, and offer an additional thing to check:

Python script connecting would work from commandline on my (linux) machine, but some users had problems connecting - that it worked from CLI suggested the DSN and credentials were right. The issue for us was that the group security policy required the ODBC credentials to be set on every machine. Once we added that (for some reason, the user had three of the four ODBC credentials they needed for our various systems), they were able to connect.

You can of course do that at group level, but as it was a simple omission on the part of one machine, I did it in Control Panel > ODBC Drivers > New

In React, the component will re-render (or update) only if the state or the prop changes.

In your case you have to update the state immediately after the change so that the component will re-render with the updates state value.

onTodoChange(event) {
        // update the state
    this.setState({name: event.target.value});
}

You can effectively "empty" the Recycle Bin from the command line by permanently deleting the Recycle Bin directory on the drive that contains the system files. (In most cases, this will be the C: drive, but you shouldn't hardcode that value because it won't always be true. Instead, use the %systemdrive% environment variable.)

The reason that this tactic works is because each drive has a hidden, protected folder with the name $Recycle.bin, which is where the Recycle Bin actually stores the deleted files and folders. When this directory is deleted, Windows automatically creates a new directory.

So, to remove the directory, use the rd command (r?emove d?irectory) with the /s parameter, which indicates that all of the files and directories within the specified directory should be removed as well:

rd /s %systemdrive%\$Recycle.bin

Do note that this action will permanently delete all files and folders currently in the Recycle Bin from all user accounts. Additionally, you will (obviously) have to run the command from an elevated command prompt in order to have sufficient privileges to perform this action.

An improved version of merge on Gson's JsonObjects - can go any level of nested structure
 /**
 * Merge "source" into "target".

 *     An improved version of merge on Gson's JsonObjects - can go any level of nested structure:
 *             1. merge root & nested attributes.
 *             2. replace list of strings. For. eg.
 *              source -> "listOfStrings": ["A!"]
 *              dest -> "listOfStrings": ["A", "B"]
 *              merged -> "listOfStrings": ["A!", "B"]
 *             3. can merge nested objects inside list. For. eg.
 *              source -> "listOfObjects": [{"key2": "B"}]
 *              dest -> "listOfObjects": [{"key1": "A"}]
 *              merged -> "listOfObjects": [{"key1": "A"}, {"key2": "B"}]
 * </pre>

The list comprehensions actually are implemented more efficiently than explicit looping (see the dis output for example functions) and the map way has to invoke an ophaque callable object on every iteration, which incurs considerable overhead overhead.

Regardless, [[] for _dummy in xrange(n)] is the right way to do it and none of the tiny (if existent at all) speed differences between various other ways should matter. Unless of course you spend most of your time doing this - but in that case, you should work on your algorithms instead. How often do you create these lists?

1. After closing the Conflict Error Dialog; from the Project Explorer, right click on the head of the project -> Team -> Stashes -> Stash Changes
2. Enter a name for your stash. E.G. "Conflict"
3. Try Pulling again. Hopefully there are no errors this time.
4. From the Git Repository view, expand your repository -> Stashed Commits
5. Right Click on the stash you created in step 2 -> Apply Stashed Changes
6. This brings up the merge tool if it can't automatically merge it.
7. Manually resolve the merge conflicts in the file/s.
8. Right Click on the file editor -> Team -> Add To Index
9. If you are not ready to commit the file or just don't want it in the Index, right click on the file editor -> Team -> Remove from Index.
10. Cleanup: From the Git Repository view, right Click on the stash you created in step 2 -> Delete Stashed Commit

For me it was due to "multiple" attribute on select input control as Angular has different ValueAccessor for this type of control.

const countryControl = new FormControl();

And inside template use like this

    <select multiple name="countries" [formControl]="countryControl">
      <option *ngFor="let country of countries" [ngValue]="country">
       {{ country.name }}
      </option>

Just make a selector for tables inside a MyClass.

.MyClass td {border: solid 1px red;}
.MyClass table td {border: none}

(To generically apply to all inner tables, you could also do table table td.)

Removing a file from pull request but not from your local repository.

1. Go to your branch from where you created the request use the following commands

git checkout -- c:\temp..... next git checkout origin/master -- c:\temp... u replace origin/master with any other branch. Next git commit -m c:\temp..... Next git push origin

Note : no single quote or double quotes for the filepath

dividend % divisor

Dividend is the numeric expression to divide. Dividend must be any expression of integer data type in sql server.

Divisor is the numeric expression to divide the dividend. Divisor must be expression of integer data type except in sql server.

SELECT 15 % 2

Output
1

Dividend = 15

Divisor = 2

Let's say you wanted to query

Query a list of CITY names from STATION with even ID numbers only.

Schema structure for STATION:

ID Number

CITY varchar

STATE varchar


select CITY from STATION as st where st.id % 2 = 0

Will fetch the even set of records 


In order to fetch the odd records with Id as odd number.

select CITY from STATION as st where st.id % 2 <> 0

% function reduces the value to either 0 or 1

Twisted has SSH support : http://www.devshed.com/c/a/Python/SSH-with-Twisted/

The twisted.conch package adds SSH support to Twisted. This chapter shows how you can use the modules in twisted.conch to build SSH servers and clients.

Setting Up a Custom SSH Server

The command line is an incredibly efficient interface for certain tasks. System administrators love the ability to manage applications by typing commands without having to click through a graphical user interface. An SSH shell is even better, as it’s accessible from anywhere on the Internet.

You can use twisted.conch to create an SSH server that provides access to a custom shell with commands you define. This shell will even support some extra features like command history, so that you can scroll through the commands you’ve already typed.

How Do I Do That? Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver , but with higher-level features for controlling the terminal.

Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver, but with higher-level features for controlling the terminal.

To make your shell available through SSH, you need to implement a few different classes that twisted.conch needs to build an SSH server. First, you need the twisted.cred authentication classes: a portal, credentials checkers, and a realm that returns avatars. Use twisted.conch.avatar.ConchUser as the base class for your avatar. Your avatar class should also implement twisted.conch.interfaces.ISession , which includes an openShell method in which you create a Protocol to manage the user’s interactive session. Finally, create a twisted.conch.ssh.factory.SSHFactory object and set its portal attribute to an instance of your portal.

Example 10-1 demonstrates a custom SSH server that authenticates users by their username and password. It gives each user a shell that provides several commands.

Example 10-1. sshserver.py

Slight modification of other answers from here that worked for me. My group has two values to group on, so I was able to just put them both in the first arg with a + to get it to alternate correctly

= Iif ( RunningValue (Fields!description.Value + Fields!name.Value, CountDistinct, Nothing) Mod 2 = 0,"#e6eed5", "Transparent")

I struggled for a while about this. Stupid rule for __init__. It is two "_" together to be "__"

Check below link: Specially "Install 32 bit libraries (if you're on 64 bit)"

 https://github.com/meteor/meteor/wiki/Mobile-Dev-Install:-Android-on-Linux

Let's take an example: You want to contribute to django, so you fork its repository. In the while you work on your feature, there is much work done on the original repo by other people. So the code you forked is not the most up to date. setting a remote upstream and fetching it time to time makes sure your forked repo is in sync with the original repo.

In such cases, you can convert the values of enum to a List and stream through it. Something like below examples. I would recommend using filter().

Using ForEach:

List<Category> category = Arrays.asList(Category.values());
category.stream().forEach(eachCategory -> {
            if(eachCategory.toString().equals("3")){
                String name = eachCategory.name();
            }
        });

Or, using Filter:

When you want to find with code:

List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.toString().equals("3")).findAny().orElse(null);

System.out.println(category.toString() + " " + category.name());

When you want to find with name:

List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.name().equals("Apple")).findAny().orElse(null);

System.out.println(category.toString() + " " + category.name());

Hope it helps! I know this is a very old post, but someone can get help.

The alternative for explode in php is split.

The first parameter is the delimiter, the second parameter the maximum number splits. The parts are returned without the delimiter present (except possibly the last part). When the delimiter is None, all whitespace is matched. This is the default.

>>> "Rajasekar SP".split()
['Rajasekar', 'SP']

>>> "Rajasekar SP".split('a',2)
['R','j','sekar SP']

another way is to make a REST call, if you have WebHCat (part of Hive project) installed, is

curl -i http://172.22.123.63:50111/templeton/v1/version/hive?user.name=foo

which will come back with JSON like

{"module":"hive","version":"1.2.1.2.3.0.0-2458"}

WebHCat docs has some details

If you want to check for local files first do:

@font-face {
font-family: 'Green Sans Web';
src:
    local('Green Web'),
    local('GreenWeb-Regular'),
    url('GreenWeb.ttf');
}

There is a more elaborate description of what to do here.

Although this question is quite old, and the accepted response is valid, I find it a bit unconfortable because the content of the HTTP response (HTML, XML, JSON, binary or whatever) becomes mixed with the headers.

I've found a different alternative. CURL provides an option (CURLOPT_HEADERFUNCTION) to set a callback that will be called for each response header line. The function will receive the curl object and a string with the header line.

You can use a code like this (adapted from TML response):

$cookies = Array();
$ch = curl_init('http://www.google.com/');
// Ask for the callback.
curl_setopt($ch, CURLOPT_HEADERFUNCTION, "curlResponseHeaderCallback");
$result = curl_exec($ch);
var_dump($cookies);

function curlResponseHeaderCallback($ch, $headerLine) {
    global $cookies;
    if (preg_match('/^Set-Cookie:\s*([^;]*)/mi', $headerLine, $cookie) == 1)
        $cookies[] = $cookie;
    return strlen($headerLine); // Needed by curl
}

This solution has the drawback of using a global variable, but I guess this is not an issue for short scripts. And you can always use static methods and attributes if curl is being wrapped into a class.

Apart from the <h:panelGroup> component (which comes as a bit of a surprise to me), you could use a <f:verbatim> tag with the escape parameter set to false to generate any mark-up you want. For example:

<f:verbatim escape="true">
    <div id="blah"></div>
</f:verbatim>

Bear in mind it's a little less elegant than the panelGroup solution, as you have to generate this for both the start and end tags if you want to wrap any of your JSF code with the div tag.

Alternatively, all the major UI Frameworks have a div component tag, or you could write your own.

Some of these above answers didn't work for me but this did. Just in case someone else has the same issue.

ng-show="column != 'vendorid' && column !='billingMonth'"

I'd like to add complementary information: In postman app you may use the "request" object to see your subsituted input data. (refer to https://www.getpostman.com/docs/postman/scripts/postman_sandbox in paragraph "Request/response related properties", ie.

console.log("header : " + request.headers["Content-Type"]);
console.log("body : " + request.data);
console.log("url : " + request.url);

I didn't test for header substitution but it works for url and body.

Try the following in your view to check the output from each. The first one updates when the view is called a second time. My controller uses the key ShowCreateButton and has the optional parameter _createAction with a default value - you can change this to your key/parameter

@Html.TextBox("_createAction", null, new { Value = (string)ViewBag.ShowCreateButton })
@Html.TextBox("_createAction", ViewBag.ShowCreateButton )
@ViewBag.ShowCreateButton

And yet another solution: instead of creating another loop, just bind the this to the return function.

var funcs = [];_x000D_
_x000D_
function createFunc(i) {_x000D_
  return function() {_x000D_
    console.log('My value: ' + i); //log value of i._x000D_
  }.call(this);_x000D_
}_x000D_
_x000D_
for (var i = 1; i <= 5; i++) {  //5 functions_x000D_
  funcs[i] = createFunc(i);     // call createFunc() i=5 times_x000D_
}

By binding this, solves the problem as well.

Just do it like this:

if(!document.getElementById("someId") { /Some code. Note the NOT (!) in the expresion/ };

If element with id "someId" does not exist expresion will return TRUE (NOT FALSE === TRUE) or !false === true;

try this code:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <meta name="format-detection" content="telephone-no">
        <meta name="viewport" content="user-scalable=no, initial-scale=1, minimum-scale=1, maximum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi">
        <title>Test</title>
    </head>
    <body>
      <script>
var createPerson = function (name) {
    var person;
    if (!document.getElementById(name)) {
        alert("Element does not exist. Let's create it.");
      person = document.createElement("div");
//add argument name as the ID of the element
      person.id = name;
//append element to the body of the document
      document.body.appendChild(person);
    } else {
        alert("Element exists. Lets get it by ID!");
      person = document.getElementById(name);
    }
    person.innerHTML = "HI THERE!";

};
//run the function.
createPerson("someid");
          </script>
       </body>
</html>

Try this in your browser and it should alert "Element does not exist. Let's create it."

Now add

<div id="someid"></div>

to the body of the page and try again. Voila! :)

You said you didn't want to use a translucent Activity, but that seems to be the best way to do this:

1. In your Manifest, set the Activity theme to Theme.Translucent.NoTitleBar.
2. Don't bother with a layout for your Activity, and don't call setContentView().
3. In your Activity's onCreate(), start your Service with startService().
4. Exit the Activity with finish() once you've started the Service.

In other words, your Activity doesn't have to be visible; it can simply make sure your Service is running and then exit, which sounds like what you want.

I would highly recommend showing at least a Toast notification indicating to the user that you are launching the Service, or that it is already running. It is very bad user experience to have a launcher icon that appears to do nothing when you press it.

Any object in Java can be used as a lock using a synchronized block. This will also automatically take care of releasing the lock when an exception occurs.

Object someObject = ...;

synchronized (someObject) {
  ...
}

You can read more about this here: Intrinsic Locks and Synchronization

Yes, probably you can re/create one by including -f at the end of your command

you can chnage the height and width in the code below

.checkmark {_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    left: 0;_x000D_
    height: 20px;_x000D_
    width: 20px;_x000D_
    border-radius:5px;_x000D_
    border:1px solid #ff7e02;_x000D_
}

<div class="check">_x000D_
_x000D_
     <label class="container1">Architecture/Landscape_x000D_
            _x000D_
_x000D_
    <input type="checkbox" checked="checked">_x000D_
            _x000D_
_x000D_
    <span class="checkmark"></span>_x000D_
         _x000D_
_x000D_
 </label>_x000D_
</div>

It is indeed possible with the following code

 <div href="#" id='a'>
     Hover me
 </div>

<div id='b'>
    Show me
</div>

and css

#a {
  display: block;
}

#a:hover + #b {
  display:block;
}

#b {
  display:none;
  }

Now by hovering on element #a shows element #b.

Use checked="checked" attribute if you want your checkbox to be checked.

The other answers are several years old (and do not work for Windows Phone 8.1) so I figured I'd drop in another option. I used this to parse an RSS response for a Windows Phone app:

XDocument xdoc = new XDocument();
xdoc = XDocument.Parse(xml_string);

Remove the date() part

SELECT name, datum 
FROM tasks 
WHERE datum >= NOW()

and if you use a specific date, don't forget the quotes around it and use the proper format with :

SELECT name, datum 
FROM tasks 
WHERE datum >= '2014-05-18 15:00:00'

list[:10]

will give you the first 10 elements of this list using slicing.

However, note, it's best not to use list as a variable identifier as it's already used by Python: list()

To find out more about these type of operations you might find this tutorial on lists helpful and the link @DarenThomas provided Explain Python's slice notation - thanks Daren)

I can't comment on the previous answers since I haven't tried them. However I know the following strategy works for me. It is a bit less elegant but gets the job done. It also doesn't require breaking code into chunks like some other approaches seem to do. In my case, that was not an option, because my code had recursive calls to the logic that was being looped; i.e., there was no practical way to just hop out of the loop, then be able to resume in some way by using global vars to preserve current state since those globals could be changed by references to them in a subsequent recursed call. So I needed a straight-forward way that would not offer a chance for the code to compromise the data state integrity.

Assuming the "stop script?" dialog is coming up during a for() loop executuion after a number of iterations (in my case, about 8-10), and messing with the registry is no option, here was the fix (for me, anyway):

var anarray = [];
var array_member = null;
var counter = 0; // Could also be initialized to the max desired value you want, if
                 // planning on counting downward.

function func_a()
{
 // some code
 // optionally, set 'counter' to some desired value.
 ...
 anarray = { populate array with objects to be processed that would have been
             processed by a for() }
 // 'anarry' is going to be reduced in size iteratively.  Therefore, if you need
 //  to maintain an orig. copy of it, create one, something like 'anarraycopy'.
 //  If you need only a shallow copy, use 'anarraycopy = anarray.slice(0);'
 //  A deep copy, depending on what kind of objects you have in the array, may be
 //  necessary.  The strategy for a deep copy will vary and is not discussed here.
 //  If you need merely to record the array's orig. size, set a local or
 //  global var equal to 'anarray.length;', depending on your needs.
 // - or -
 // plan to use 'counter' as if it was 'i' in a for(), as in
 // for(i=0; i < x; i++ {...}

   ...

   // Using 50 for example only.  Could be 100, etc. Good practice is to pick something
   // other than 0 due to Javascript engine processing; a 0 value is all but useless
   // since it takes time for Javascript to do anything. 50 seems to be good value to
   // use. It could be though that what value to use does  depend on how much time it
   // takes the code in func_c() to execute, so some profiling and knowing what the 
   // most likely deployed user base is going to be using might help. At the same 
   // time, this may make no difference.  Not entirely sure myself.  Also, 
   // using "'func_b()'" instead of just "func_b()" is critical.  I've found that the
   // callback will not occur unless you have the function in single-quotes.

   setTimeout('func_b()', 50);

  //  No more code after this.  function func_a() is now done.  It's important not to
  //  put any more code in after this point since setTimeout() does not act like
  //  Thread.sleep() in Java.  Processing just continues, and that is the problem
  //  you're trying to get around.

} // func_a()


function func_b()
{
 if( anarray.length == 0 )
 {
   // possibly do something here, relevant to your purposes
   return;
 }
//  -or- 
if( counter == x ) // 'x' is some value you want to go to.  It'll likely either
                   // be 0 (when counting down) or the max desired value you
                   // have for x if counting upward.
{
  // possibly do something here, relevant to your purposes
  return;
}

array_member = anarray[0];
anarray.splice(0,1); // Reduces 'anarray' by one member, the one at anarray[0].
                     // The one that was at anarray[1] is now at
                     // anarray[0] so will be used at the next iteration of func_b().

func_c();

setTimeout('func_b()', 50);

} // func_b()


function func_c()
{
  counter++; // If not using 'anarray'.  Possibly you would use
             // 'counter--' if you set 'counter' to the highest value
             // desired and are working your way backwards.

  // Here is where you have the code that would have been executed
  // in the for() loop.  Breaking out of it or doing a 'continue'
  // equivalent can be done with using 'return;' or canceling 
  // processing entirely can be done by setting a global var
  // to indicate the process is cancelled, then doing a 'return;', as in
  // 'bCancelOut = true; return;'.  Then in func_b() you would be evaluating
  // bCancelOut at the top to see if it was true.  If so, you'd just exit from
  // func_b() with a 'return;'

} // func_c()

If you're doing this in the context of a asp.Net Core API action, the conversion to Json is done implicitly.

In Sublime Text 3....Try changing the above code to this, note the addition of "start".....

"variants" : [

    { "name": "Run",
      "cmd" : ["start", "${file_base_name}.exe"]
    } 

That is a pretty standard use case for apply():

R> vec <- 1:10
R> DF <- data.frame(start=c(1,3,5,7), end=c(2,6,7,9))
R> DF$newcol <- apply(DF,1,function(row) mean(vec[ row[1] : row[2] ] ))
R> DF
  start end newcol
1     1   2    1.5
2     3   6    4.5
3     5   7    6.0
4     7   9    8.0

You can also use plyr if you prefer but here is no real need to go beyond functions from base R.

this is a bit late.. but i have seen this problem occurs when you want to insert or delete one line from/to DB but u put/pull more than one line or more than one value ,

E.g:

you want to delete one line from DB with a specific value such as id of an item but you've queried a list of ids then you will encounter the same exception message.

regards.

Another option may be this John Resig remove method. can better fit what you need. if you know the index in the array.

More simple way...:

    Dim dt As DataTable = DirectCast(GridView1.DataSource, DataTable)
    Dim dv As New DataView(dt)

    If GridView1.Attributes("dir") = SortDirection.Ascending Then
        dv.Sort = e.SortExpression & " DESC" 
        GridView1.Attributes("dir") = SortDirection.Descending

    Else
        GridView1.Attributes("dir") = SortDirection.Ascending
        dv.Sort = e.SortExpression & " ASC"

    End If

    GridView1.DataSource = dv
    GridView1.DataBind()

The java.util.Collections class has a sort method that takes a list and a custom Comparator. You can define your own Comparator to sort your Person object however you like.

As for "Open Quickly" feature - it's great, but I've always missed TextMate's cmd-shift-t for browsing the projects and files (symbols, methods, etc).

That's why I've released an Xcode plugin that provides just that. It's called Code Pilot and you might want to take a look at it: http://macoscope.net/en/mac/codepilot/

In my case, the .project file was read-only (it was pulled from the source code control system that way). Making it writable resolved the issue.

Eclipse v4.7 (Oxygen).

To attempt command line arguments directly is not possible.

One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).

This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html

so sudo systemctl restart myprog -v -- systemctl will think you're trying to set one of its flags, not myprog's flag.

sudo systemctl restart myprog someotheroption -- systemctl will restart myprog and the someotheroption service, if it exists.

Extend HttpServletRequestWrapper, override the header getters to return the parameters as well:

public class AddParamsToHeader extends HttpServletRequestWrapper {
    public AddParamsToHeader(HttpServletRequest request) {
        super(request);
    }

    public String getHeader(String name) {
        String header = super.getHeader(name);
        return (header != null) ? header : super.getParameter(name); // Note: you can't use getParameterValues() here.
    }

    public Enumeration getHeaderNames() {
        List<String> names = Collections.list(super.getHeaderNames());
        names.addAll(Collections.list(super.getParameterNames()));
        return Collections.enumeration(names);
    }
}

..and wrap the original request with it:

chain.doFilter(new AddParamsToHeader((HttpServletRequest) request), response);

That said, I personally find this a bad idea. Rather give it direct access to the parameters or pass the parameters to it.

Sexy quickselect in Python

def quickselect(arr, k):
    '''
     k = 1 returns first element in ascending order.
     can be easily modified to return first element in descending order
    '''

    r = random.randrange(0, len(arr))

    a1 = [i for i in arr if i < arr[r]] '''partition'''
    a2 = [i for i in arr if i > arr[r]]

    if k <= len(a1):
        return quickselect(a1, k)
    elif k > len(arr)-len(a2):
        return quickselect(a2, k - (len(arr) - len(a2)))
    else:
        return arr[r]

add display:block; and it'll work. Images are inline by default

To clarify, the default width for a block element is auto, which of course fills the entire available width of the containing element.

By setting the margin to auto, the browser assigns half the remaining space to margin-left and the other half to margin-right.

If you want to change the backgorund image or color of the button when it is pressed, then just copy this code and paste in your project at exact location described below.

      <!-- Create new xml file like mybtn_layout.xml file in drawable -->
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable/pressed" /> <!--pressed --> 
<item android:drawable="@drawable/normal" /> <!-- Normal -->
</selector>
  <!-- Now this file should be in a drawable folder and use this 
  single line code in    button code to get all the properties of this xml file -->

    <Button
      android:id="@+id/street_btn"
      android:layout_width="wrap_content"
      android:background="@drawable/layout_a" > <!-- your required code -->
    </Button>

The question specifically states the performance needs to be improved for ad-hoc queries, and that indexes can't be added. So taking that at face value, what can be done to improve performance on any table?

Since we're considering ad-hoc queries, the WHERE clause and the ORDER BY clause can contain any combination of columns. This means that almost regardless of what indexes are placed on the table there will be some queries that require a table scan, as seen above in query plan of a poorly performing query.

Taking this into account, let's assume there are no indexes at all on the table apart from a clustered index on the primary key. Now let's consider what options we have to maximize performance.

• Defragment the table

  As long as we have a clustered index then we can defragment the table using DBCC INDEXDEFRAG (deprecated) or preferably ALTER INDEX. This will minimize the number of disk reads required to scan the table and will improve speed.

• Use the fastest disks possible. You don't say what disks you're using but if you can use SSDs.

• Optimize tempdb. Put tempdb on the fastest disks possible, again SSDs. See this SO Article and this RedGate article.

• As stated in other answers, using a more selective query will return less data, and should be therefore be faster.

Now let's consider what we can do if we are allowed to add indexes.

If we weren't talking about ad-hoc queries, then we would add indexes specifically for the limited set of queries being run against the table. Since we are discussing ad-hoc queries, what can be done to improve speed most of the time?

• Add a single column index to each column. This should give SQL Server at least something to work with to improve the speed for the majority of queries, but won't be optimal.
• Add specific indexes for the most common queries so they are optimized.
• Add additional specific indexes as required by monitoring for poorly performing queries.

Edit

I've run some tests on a 'large' table of 22 million rows. My table only has six columns but does contain 4GB of data. My machine is a respectable desktop with 8Gb RAM and a quad core CPU and has a single Agility 3 SSD.

I removed all indexes apart from the primary key on the Id column.

A similar query to the problem one given in the question takes 5 seconds if SQL server is restarted first and 3 seconds subsequently. The database tuning advisor obviously recommends adding an index to improve this query, with an estimated improvement of > 99%. Adding an index results in a query time of effectively zero.

What's also interesting is that my query plan is identical to yours (with the clustered index scan), but the index scan accounts for 9% of the query cost and the sort the remaining 91%. I can only assume your table contains an enormous amount of data and/or your disks are very slow or located over a very slow network connection.

TLDR : check if packaging element inside the pom.xml file is set to jar.

Like this - <packaging>jar</packaging>. If it set to pom your target folder will not be created even after you Clean and Build your project and Maven executable won't be able to find .class files (because they don't exist), after which you get Error: Could not find or load main class your.package.name.MainClass

After creating a Maven POM project in Netbeans 8.2, the content of the default pom.xml file are as follows -

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   <modelVersion>4.0.0</modelVersion>
   <groupId>com.mycompany</groupId>
   <artifactId>myproject</artifactId>
   <version>1.0-SNAPSHOT</version>
   <packaging>pom</packaging>
   <properties>
       <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   </properties>
</project>

Here packaging element is set to pom. Hence the target directory is not created as we are not enabling maven to package our application as a jar file. Change it to jar then Clean and Build your project, you should see target directory created at root location. Now you should be able to run that java file with main method.

When no packaging is declared, Maven assumes the packaging as jar. Other core packaging values are pom, war, maven-plugin, ejb, ear, rar. These define the goals that execute on each corresponsding build life-cycle phase of that package. See more here
