I had the problem before, but it was solved. The main problem was that I mistakenly spell the int main() function. Instead of writing int main() I wrote int mian()....Cheers !

Another way you can get this linker error (as I was) is if you are exporting an instance of a class from a DLL file, but have not declared that class itself as import/export.

#ifdef  MYDLL_EXPORTS
   #define DLLEXPORT __declspec(dllexport)
#else
   #define DLLEXPORT __declspec(dllimport)
#endif

class DLLEXPORT Book // <--- This class must also be declared as export/import
{
    public:
        Book();
        ~Book();
        int WordCount();
};

DLLEXPORT extern Book book; // <-- This is what I really wanted, to export book object

So even though primarily I was exporting just an instance of the Book class called book above, I had to declare the Book class as export/import class as well otherwise calling book.WordCount() in the other DLL file was causing a link error.

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

Just to add to the helpful and detailed answer:

If you have to check the exit code explicitly, it is better to use the arithmetic operator, (( ... )), this way:

run_some_command
(($? != 0)) && { printf '%s\n' "Command exited with non-zero"; exit 1; }

Or, use a case statement:

run_some_command; ec=$?  # grab the exit code into a variable so that it can
                         # be reused later, without the fear of being overwritten
case $ec in
    0) ;;
    1) printf '%s\n' "Command exited with non-zero"; exit 1;;
    *) do_something_else;;
esac

The Google reCAPTCHA version 2 ASP.Net allows validating the Captcha response on the client side using its Callback functions. In this example, the Google new reCAPTCHA will be validated using ASP.Net RequiredField Validator.

<script type="text/javascript">

        grecaptcha.render('dvCaptcha', {

If you are using C#, you do not need to escape it.

cout.fill('*');
cout << -12345 << endl; // print default value with no field width
cout << setw(10) << -12345 << endl; // print default with field width
cout << setw(10) << left << -12345 << endl; // print left justified
cout << setw(10) << right << -12345 << endl; // print right justified
cout << setw(10) << internal << -12345 << endl; // print internally justified

This produces the output:

-12345
****-12345
-12345****
****-12345
-****12345

The problem is that you set cipherText to empty string at every cycle iteration, the line

cipherText = ""

must be moved before the loop.

Ok, you are trying to access the GUI via another thread. This, in the main, is not good practice.

The AsyncTask executes everything in doInBackground() inside of another thread, which does not have access to the GUI where your views are.

preExecute() and postExecute() offer you access to the GUI before and after the heavy lifting occurs in this new thread, and you can even pass the result of the long operation to postExecute() to then show any results of processing.

See these lines where you are later updating your TextView:

TextView txt = findViewById(R.id.output);
txt.setText("Executed");

Put them in onPostExecute().

You will then see your TextView text updated after the doInBackground completes.

I noticed that your onClick listener does not check to see which View has been selected. I find the easiest way to do this is via switch statements. I have a complete class edited below with all suggestions to save confusion.

import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.provider.Settings.System;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.view.View.OnClickListener;

public class AsyncTaskActivity extends Activity implements OnClickListener {

    Button btn;
    AsyncTask<?, ?, ?> runningTask;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        btn = findViewById(R.id.button1);

        // Because we implement OnClickListener, we only
        // have to pass "this" (much easier)
        btn.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        // Detect the view that was "clicked"
        switch (view.getId()) {
        case R.id.button1:
            if (runningTask != null)
                runningTask.cancel(true);
            runningTask = new LongOperation();
            runningTask.execute();
            break;
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        // Cancel running task(s) to avoid memory leaks
        if (runningTask != null)
            runningTask.cancel(true);
    }

    private final class LongOperation extends AsyncTask<Void, Void, String> {

        @Override
        protected String doInBackground(Void... params) {
            for (int i = 0; i < 5; i++) {
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    // We were cancelled; stop sleeping!
                }
            }
            return "Executed";
        }

        @Override
        protected void onPostExecute(String result) {
            TextView txt = (TextView) findViewById(R.id.output);
            txt.setText("Executed"); // txt.setText(result);
            // You might want to change "executed" for the returned string
            // passed into onPostExecute(), but that is up to you
        }
    }
}

Carry Flag is a flag set when:

a) two unsigned numbers were added and the result is larger than "capacity" of register where it is saved. Ex: we wanna add two 8 bit numbers and save result in 8 bit register. In your example: 255 + 9 = 264 which is more that 8 bit register can store. So the value "8" will be saved there (264 & 255 = 8) and CF flag will be set.

b) two unsigned numbers were subtracted and we subtracted the bigger one from the smaller one. Ex: 1-2 will give you 255 in result and CF flag will be set.

Auxiliary Flag is used as CF but when working with BCD. So AF will be set when we have overflow or underflow on in BCD calculations. For example: considering 8 bit ALU unit, Auxiliary flag is set when there is carry from 3rd bit to 4th bit i.e. carry from lower nibble to higher nibble. (Wiki link)

Overflow Flag is used as CF but when we work on signed numbers. Ex we wanna add two 8 bit signed numbers: 127 + 2. the result is 129 but it is too much for 8bit signed number, so OF will be set. Similar when the result is too small like -128 - 1 = -129 which is out of scope for 8 bit signed numbers.

You can read more about flags on wikipedia

You haven't specified what the query should return if more than one document is added at the same time, so this query assumes you want all of them returned:

SELECT t.ID,
       t.USER_ID,
       t.DATE_ADDED,
       t.DATE_VIEWED,
       t.DOCUMENT_ID,
       t.URL,
       t.DOCUMENT_TITLE,
       t.DOCUMENT_DATE
FROM (
  SELECT test_table.*,
         RANK()
         OVER (ORDER BY DOCUMENT_DATE DESC) AS the_rank
  FROM   test_table
  WHERE  user_id = value
  )
WHERE the_rank = 1;

This query will only make one pass through the data.

Update

See my other SO answer.

Original

var request = (HttpWebRequest)WebRequest.Create("https://example.com/endpoint");

string stringData = ""; // place body here
var data = Encoding.Default.GetBytes(stringData); // note: choose appropriate encoding

request.Method = "PUT";
request.ContentType = ""; // place MIME type here
request.ContentLength = data.Length;

var newStream = request.GetRequestStream(); // get a ref to the request body so it can be modified
newStream.Write(data, 0, data.Length);
newStream.Close();

I wanted the scrollView to scroll directly after onCreateView() (not after e.g. a button click). To get it to work I needed to use a ViewTreeObserver:

mScrollView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            mScrollView.post(new Runnable() {
                public void run() {
                    mScrollView.fullScroll(View.FOCUS_DOWN);
                }
            });
        }
    });

But beware that this will be called everytime something gets layouted (e.g if you set a view invisible or similar) so don't forget to remove this listener if you don't need it anymore with:

public void removeGlobalOnLayoutListener (ViewTreeObserver.OnGlobalLayoutListener victim) on SDK Lvl < 16

or

public void removeOnGlobalLayoutListener (ViewTreeObserver.OnGlobalLayoutListener victim) in SDK Lvl >= 16

all answers are great, and it seems that no more answer is needed but I just wonted to point out something about && operator called dependent condition

In expressions using operator &&, a condition—we’ll call this the dependent condition—may require another condition to be true for the evaluation of the dependent condition to be meaningful.

In this case, the dependent condition should be placed after the && operator to prevent errors.

Consider the expression (i != 0) && (10 / i == 2). The dependent condition (10 / i == 2) must appear after the && operator to prevent the possibility of division by zero.

another example (myObject != null) && (myObject.getValue() == somevaluse)

and another thing: && and || are called short-circuit evaluation because the second argument is executed or evaluated only if the first argument does not suffice to determine the value of the expression

Use this convertor , It doesn't fail at all: Services_Json

// create a new instance of Services_JSON
$json = new Services_JSON();

// convert a complexe value to JSON notation, and send it to the browser
$value = array('foo', 'bar', array(1, 2, 'baz'), array(3, array(4)));
$output = $json->encode($value);
print($output);
// prints: ["foo","bar",[1,2,"baz"],[3,[4]]]

// accept incoming POST data, assumed to be in JSON notation
$input = file_get_contents('php://input', 1000000);
$value = $json->decode($input);

// if you want to convert json to php arrays:
$json = new Services_JSON(SERVICES_JSON_LOOSE_TYPE);

Use position:fixed; and set the top:0;left:0;right:0;height:100px; and you should be able to have it "stick" to the top of the page.

Here is another method to get date

new Date().getDate()          // Get the day as a number (1-31)
new Date().getDay()           // Get the weekday as a number (0-6)
new Date().getFullYear()      // Get the four digit year (yyyy)
new Date().getHours()         // Get the hour (0-23)
new Date().getMilliseconds()  // Get the milliseconds (0-999)
new Date().getMinutes()       // Get the minutes (0-59)
new Date().getMonth()         // Get the month (0-11)
new Date().getSeconds()       // Get the seconds (0-59)
new Date().getTime()          // Get the time (milliseconds since January 1, 1970)

for i in range(1,11):
    print(i)

i know this is an old question but i think this works now

.NET languages can be as fast as C++ code, or even faster, but C++ code will have a more constant throughput as the .NET runtime has to pause for GC, even if it's very clever about its pauses.

So if you have some code that has to consistently run fast without any pause, .NET will introduce latency at some point, even if you are very careful with the runtime GC.

you can use the DBMS_SQL.DESCRIBE_COLUMNS2

Actually, you can try WindowManager.LayoutParams.TYPE_SYSTEM_ERROR instead of TYPE_SYSTEM_OVERLAY. It may sound like a hack, but it let you display view on top of everything and still get touch events.

For me, I just had to tell FileZilla where the private keys were:

1. Select Edit > Settings from the main menu
2. In the Settings dialog box, go to Connection > SFTP
3. Click the "Add key file..." button
4. Navigate to and then select the desired PEM file(s)

Another solution I've used to create lighter fontawesome icons, similar to the webkit-text-stroke approach but more portable, is to set the color of the icon to the same as the background (or transparent) and use text-shadow to create an outline:

.fa-outline-dark-gray {
    color: #fff;
    text-shadow: -1px -1px 0 #999,
            1px -1px 0 #999,
           -1px 1px 0 #999,
            1px 1px 0 #999;
}

It doesn't work in ie <10, but at least it's not restricted to webkit browsers.

I had this same problem. For me, it was due to Cache-Control header being set at the server level in IIS to no-cache, no-store. So for my application I had to add in the below to my web.config:

<httpProtocol>
    <customHeaders>
        <remove name="Cache-Control" />
    </customHeaders>
</httpProtocol>

As @kgrad says, /* */ does not nest and can cause errors. A better answer is:

// LINE *of code* I WANT COMMENTED 
// LINE *of code* I WANT COMMENTED 
// LINE *of code* I WANT COMMENTED 

Most IDEs have a single keyboard command for doing/undoing this, so there's really no reason to use the other style any more. For example: in eclipse, select the block of text and hit Ctrl+/
To undo that type of comment, use Ctrl+\

UPDATE: The Sun coding convention says that this style should not be used for block text comments:

// Using the slash-slash
// style of comment as shown
// in this paragraph of non-code text is 
// against the coding convention.

but // can be used 3 other ways:

1. A single line comment
2. A comment at the end of a line of code
3. Commenting out a block of code

Here is the simple logic to find Biggest/Largest Number

Input : 11, 33, 1111, 4, 0 Output : 1111

namespace PurushLogics
{
    class Purush_BiggestNumber
    {
        static void Main()

            Console.WriteLine("Enter Total Number of Integers\n");
            count = int.Parse(Console.ReadLine());

            int[] numbers = new int[count];

            Console.WriteLine("Enter the numbers"); // Input 44, 55, 111, 2 Output = "111"
            for (int temp = 0; temp < count; temp++)
            {
                numbers[temp] = int.Parse(Console.ReadLine());
            }

            int largest = numbers[0];
            for (int big = 1; big < numbers.Length; big++)
            {
                if (largest < numbers[big])
                {
                    largest = numbers[big];
                }
            }
            Console.WriteLine(largest);

Have you tried editing the history file directly:

~/.bash_history

Row(
 children: <Widget>[
  Flexible(

 ])

This works for me, there are 3 widgets inside row: Flexible, Container, Flexible

Your code requires that the Dog class has overridden the toString() method so that it knows how to print itself out. Otherwise, your code looks correct.

you need to identify sql version.

SQLServerManager15.msc for [SQL Server 2019] or

SQLServerManager14.msc for [SQL Server 2017] or

SQLServerManager13.msc for [SQL Server 2016] or

SQLServerManager12.msc for [SQL Server 2014] or

SQLServerManager11.msc for [SQL Server 2012] or

SQLServerManager10.msc for [SQL Server 2008],

Step :1) open ssms

  2) select version

  3) select above command and run in cmd with admin right.

I used it recently:

By default, the access modifier for a class is internal. That means to say, a class is accessible within the same assembly. But if we want the class to be accessed from other assemblies then it has to be made public.

You can use include=FALSE to exclude everything in a chunk.

```{r include=FALSE}
source("C:/Rscripts/source.R")
```

If you only want to suppress messages, use message=FALSE instead:

```{r message=FALSE}
source("C:/Rscripts/source.R")
```

Try to look at Net2Java It seems to me the best option for automatic (or semi-automatic at least) conversion from C# to Java

You are creating those bytes objects yourself:

item['title'] = [t.encode('utf-8') for t in title]
item['link'] = [l.encode('utf-8') for l in link]
item['desc'] = [d.encode('utf-8') for d in desc]
items.append(item)

Each of those t.encode(), l.encode() and d.encode() calls creates a bytes string. Do not do this, leave it to the JSON format to serialise these.

Next, you are making several other errors; you are encoding too much where there is no need to. Leave it to the json module and the standard file object returned by the open() call to handle encoding.

You also don't need to convert your items list to a dictionary; it'll already be an object that can be JSON encoded directly:

class W3SchoolPipeline(object):    
    def __init__(self):
        self.file = open('w3school_data_utf8.json', 'w', encoding='utf-8')

    def process_item(self, item, spider):
        line = json.dumps(item) + '\n'
        self.file.write(line)
        return item

I'm guessing you followed a tutorial that assumed Python 2, you are using Python 3 instead. I strongly suggest you find a different tutorial; not only is it written for an outdated version of Python, if it is advocating line.decode('unicode_escape') it is teaching some extremely bad habits that'll lead to hard-to-track bugs. I can recommend you look at Think Python, 2nd edition for a good, free, book on learning Python 3.

You could use <jsp:include> for this.

<jsp:include page="/servletURL" />

It's however usually the other way round. You call the servlet which in turn forwards to the JSP to display the results. Create a Servlet which does something like following in doGet() method.

request.setAttribute("result", "This is the result of the servlet call");
request.getRequestDispatcher("/WEB-INF/result.jsp").forward(request, response);

and in /WEB-INF/result.jsp

<p>The result is ${result}</p>

Now call the Servlet by the URL which matches its <url-pattern> in web.xml, e.g. http://example.com/contextname/servletURL.

Do note that the JSP file is explicitly placed in /WEB-INF folder. This will prevent the user from opening the JSP file individually. The user can only call the servlet in order to open the JSP file.

If your actual question is "How to submit a form to a servlet?" then you just have to specify the servlet URL in the HTML form action.

<form action="servletURL" method="post">

Its doPost() method will then be called.

It happens mostly when JQuery is not installed in your project. Install JQuery in your project by following commands according to your package manager.

Yarn

yarn add jquery

npm

npm i jquery --save

After this just import $ in your project file. import $ from 'jquery'

GridView1.Columns[columnIndex].Visible = false;

I have a rooted Samsung Galaxy Trend Plus (GT-S7580).

Running 'adb root' gives me the same 'adbd cannot run as root in production builds' error.

For devices that have Developer Options -> Root access, choose "ADB only" to provide adb root access to the device (as suggested by NgaNguyenDuy).

Then try to run the command as per the solution at Launch a script as root through ADB. In my case, I just wanted to run the 'netcfg rndis0 dhcp' command, and I did it this way:

adb shell "su -c netcfg rndis0 dhcp"

Please check whether you are making any mistakes while running it this way.

If it still does not work, check whether you rooted the device correctly. If still no luck, try installing a custom ROM such as Cyanogen Mod in order for 'adb root' to work.

Look at the methods in the java.io.File class:

File file = new File("yourfileName");
String path = file.getAbsolutePath();

Normal text editors are nano, or vi.

For example:

root@user:# nano galfit.feedme

or

root@user:# vi galfit.feedme

TLDR;

use location.href or better use window.location.href;

However if you read this you will gain undeniable proof.

The truth is it's fine to use but why do things that are questionable. You should take the higher road and just do it the way that it probably should be done.

location = "#/mypath/otherside"
var sections = location.split('/')

This code is perfectly correct syntax-wise, logic wise, type-wise you know the only thing wrong with it?

it has location instead of location.href

what about this

var mystring = location = "#/some/spa/route"

what is the value of mystring? does anyone really know without doing some test. No one knows what exactly will happen here. Hell I just wrote this and I don't even know what it does. location is an object but I am assigning a string will it pass the string or pass the location object. Lets say there is some answer to how this should be implemented. Can you guarantee all browsers will do the same thing?

This i can pretty much guess all browsers will handle the same.

var mystring = location.href = "#/some/spa/route"

What about if you place this into typescript will it break because the type compiler will say this is suppose to be an object?

This conversation is so much deeper than just the location object however. What this conversion is about what kind of programmer you want to be?

If you take this short-cut, yea it might be okay today, ye it might be okay tomorrow, hell it might be okay forever, but you sir are now a bad programmer. It won't be okay for you and it will fail you.

There will be more objects. There will be new syntax.

You might define a getter that takes only a string but returns an object and the worst part is you will think you are doing something correct, you might think you are brilliant for this clever method because people here have shamefully led you astray.

var Person.name = {first:"John":last:"Doe"}
console.log(Person.name) // "John Doe"

With getters and setters this code would actually work, but just because it can be done doesn't mean it's 'WISE' to do so.

Most people who are programming love to program and love to get better. Over the last few years I have gotten quite good and learn a lot. The most important thing I know now especially when you write Libraries is consistency and predictability.

Do the things that you can consistently do.

+"2" <-- this right here parses the string to a number. should you use it? or should you use parseInt("2")?

what about var num =+"2"?

From what you have learn, from the minds of stackoverflow i am not too hopefully.

If you start following these 2 words consistent and predictable. You will know the right answer to a ton of questions on stackoverflow.

Let me show you how this pays off. Normally I place ; on every line of javascript i write. I know it's more expressive. I know it's more clear. I have followed my rules. One day i decided not to. Why? Because so many people are telling me that it is not needed anymore and JavaScript can do without it. So what i decided to do this. Now because I have become sure of my self as a programmer (as you should enjoy the fruit of mastering a language) i wrote something very simple and i didn't check it. I erased one comma and I didn't think I needed to re-test for such a simple thing as removing one comma.

I wrote something similar to this in es6 and babel

var a = "hello world"
(async function(){
  //do work
})()

This code fail and took forever to figure out. For some reason what it saw was

var a = "hello world"(async function(){})()

hidden deep within the source code it was telling me "hello world" is not a function.

For more fun node doesn't show the source maps of transpiled code.

Wasted so much stupid time. I was presenting to someone as well about how ES6 is brilliant and then I had to start debugging and demonstrate how headache free and better ES6 is. Not convincing is it.

I hope this answered your question. This being an old question it's more for the future generation, people who are still learning.

Question when people say it doesn't matter either way works. Chances are a wiser more experienced person will tell you other wise.

what if someone overwrite the location object. They will do a shim for older browsers. It will get some new feature that needs to be shimmed and your 3 year old code will fail.

My last note to ponder upon.

Writing clean, clear purposeful code does something for your code that can't be answer with right or wrong. What it does is it make your code an enabler.

You can use more things plugins, Libraries with out fear of interruption between the codes.

for the record. use

window.location.href

Simple function to alert contents of an object or an array .
Call this function with an array or string or an object it alerts the contents.

Function

function print_r(printthis, returnoutput) {
    var output = '';

    if($.isArray(printthis) || typeof(printthis) == 'object') {
        for(var i in printthis) {
            output += i + ' : ' + print_r(printthis[i], true) + '\n';
        }
    }else {
        output += printthis;
    }
    if(returnoutput && returnoutput == true) {
        return output;
    }else {
        alert(output);
    }
}

Usage

var data = [1, 2, 3, 4];
print_r(data);

For spark scala I typically use when I can't use the spark csv packages...

val sqlContext = new org.apache.spark.sql.SQLContext(sc)
val rawdata = sc.textFile("hdfs://example.host:8020/user/example/example.csv")
val header = rawdata.first()
val tbldata = rawdata.filter(_(0) != header(0))

just add /FORCE as linker flag and you're all set.

for instance, if you're working on CMakeLists.txt. Then add following line:

SET(CMAKE_EXE_LINKER_FLAGS  "/FORCE")

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

You don't need to go level up and use .. since all buttons are on the same level:

//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']

I tried all the non-plugin approaches here, but all caused blank pages to print after the content, or had other problems. Here's my solution:

Html:

<body>
<div id="page-content">        
    <div id="printme">Content To Print</div>
    <div>Don't print this.</div>
</div>
<div id="hidden-print-div"></div>
</body>

Jquery:

    $(document).ready(function () {
        $("#hidden-print-div").html($("#printme").html());
    });

Css:

    #hidden-print-div {
        display: none;
    }

    @media print {
        #hidden-print-div {
            display: block;
        }

        #page-content {
            display: none;
        }
    }

AForge.net is a free (open-source) library with Fast Fourier Transform support. (See Sources/Imaging/ComplexImage.cs for usage, Sources/Math/FourierTransform.cs for implemenation)

Can't you just get the size/length of the set/array, generate a random number between 0 and the size/length, then call the element whose index matches that number? HashSet has a .size() method, I'm pretty sure.

In psuedocode -

function randFromSet(target){
 var targetLength:uint = target.length()
 var randomIndex:uint = random(0,targetLength);
 return target[randomIndex];
}

For those who use the latest 3-19 eclipse build:

It just happened to me when upgrading from Oxygen to 3-19 eclipse version, so I assume the auto-complete feature does not migrated correctly during the upgrade process.

The only solution that worked for me was to create a new eclipse workspace, and import the project/s to it. It might take a few minutes, but it worth it - comparing to the time spent on other solutions...

First, check that your origin is set by running

git remote -v

This should show you all of the push / fetch remotes for the project.

If this returns with no output, skip to last code block.

Verify remote name / address

If this returns showing that you have remotes set, check that the name of the remote matches the remote you are using in your commands.

$git remote -v
myOrigin ssh://[email protected]:1234/myRepo.git (fetch)
myOrigin ssh://[email protected]:1234/myRepo.git (push)

# this will fail because `origin` is not set
$git push origin master

# you need to use
$git push myOrigin master

If you want to rename the remote or change the remote's URL, you'll want to first remove the old remote, and then add the correct one.

Remove the old remote

$git remote remove myOrigin

Add missing remote

You can then add in the proper remote using

$git remote add origin ssh://[email protected]:1234/myRepo.git

# this will now work as expected
$git push origin master

This did it for my case.

How to compile a plugin - For making VST plugins in C++Builder, first you need the VST sdk by Steinberg. It's available from the Yvan Grabit's site (the link is at the top of the page).

The next thing you need to do is create a .def file (for example : myplugin.def). This needs to contain at least the following lines:

EXPORTS main=_main

Borland compilers add an underscore to function names, and this exports the main() function the way a VST host expects it. For more information about .def files, see the C++Builder help files.

This is not enough, though. If you're going to use any VCL element (anything to do with forms or components), you have to take care your plugin doesn't crash Cubase (or another VST host, for that matter). Here's how:

1. Include float.h.

2. In the constructor of your effect class, write

   _control87(PC_64|MCW_EM,MCW_PC|MCW_EM);
   

That should do the trick.

if you created your elements dynamically(using javascript), then this code doesn't work. Because, .click() will attach events to elements that already exists. As you are dynamically creating your elements using javascript, it doesn't work.

For this you have to use some other functions which works on dynamically created elements. This can be done in different ways..

Earlier we have .live() function

$('selector').live('click', function()
{
//your code
});

but .live() is deprecated.This can be replaced by other functions.

Delegate():

Using delegate() function you can click on dynamically generated HTML elements.

Example:

$(document).delegate('selector', 'click', function()
{
 //your code
});

EDIT: The delegate() method was deprecated in version 3.0. Use the on() method instead.

ON():

Using on() function you can click on dynamically generated HTML elements.

Example:

$(document).on('click', 'selector', function()
{
// your code
});

You can display an image in your own window using Tkinter, w/o depending on image viewers installed in your system:

import Tkinter as tk
from PIL import Image, ImageTk  # Place this at the end (to avoid any conflicts/errors)

window = tk.Tk()
#window.geometry("500x500") # (optional)    
imagefile = {path_to_your_image_file}
img = ImageTk.PhotoImage(Image.open(imagefile))
lbl = tk.Label(window, image = img).pack()
window.mainloop()

For Python 3, replace import Tkinter as tk with import tkinter as tk.

In case you're using ASP.NET 5 with ASP.NET MVC 6, most of these answers simply won't work because you'll normally let MVC create the appropriate route collection for you (using the default RESTful conventions), meaning that you won't find any Routes.MapRoute() call to edit at will.

The ConfigureServices() method invoked by the Startup.cs file will register MVC with the Dependency Injection framework built into ASP.NET 5: that way, when you call ApplicationBuilder.UseMvc() later in that class, the MVC framework will automatically add these default routes to your app. We can take a look of what happens behind the hood by looking at the UseMvc() method implementation within the framework source code:

public static IApplicationBuilder UseMvc(
    [NotNull] this IApplicationBuilder app,
    [NotNull] Action<IRouteBuilder> configureRoutes)
{
    // Verify if AddMvc was done before calling UseMvc
    // We use the MvcMarkerService to make sure if all the services were added.
    MvcServicesHelper.ThrowIfMvcNotRegistered(app.ApplicationServices);

    var routes = new RouteBuilder
    {
        DefaultHandler = new MvcRouteHandler(),
        ServiceProvider = app.ApplicationServices
    };

    configureRoutes(routes);

    // Adding the attribute route comes after running the user-code because
    // we want to respect any changes to the DefaultHandler.
    routes.Routes.Insert(0, AttributeRouting.CreateAttributeMegaRoute(
        routes.DefaultHandler,
        app.ApplicationServices));

    return app.UseRouter(routes.Build());
}

The good thing about this is that the framework now handles all the hard work, iterating through all the Controller's Actions and setting up their default routes, thus saving you some redundant work.

The bad thing is, there's little or no documentation about how you could add your own routes. Luckily enough, you can easily do that by using either a Convention-Based and/or an Attribute-Based approach (aka Attribute Routing).

Convention-Based

In your Startup.cs class, replace this:

app.UseMvc();

with this:

app.UseMvc(routes =>
            {
                // Route Sample A
                routes.MapRoute(
                    name: "RouteSampleA",
                    template: "MyOwnGet",
                    defaults: new { controller = "Items", action = "Get" }
                );
                // Route Sample B
                routes.MapRoute(
                    name: "RouteSampleB",
                    template: "MyOwnPost",
                    defaults: new { controller = "Items", action = "Post" }
                );
            });

Attribute-Based

A great thing about MVC6 is that you can also define routes on a per-controller basis by decorating either the Controller class and/or the Action methods with the appropriate RouteAttribute and/or HttpGet / HttpPost template parameters, such as the following:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNet.Mvc;

namespace MyNamespace.Controllers
{
    [Route("api/[controller]")]
    public class ItemsController : Controller
    {
        // GET: api/items
        [HttpGet()]
        public IEnumerable<string> Get()
        {
            return GetLatestItems();
        }

        // GET: api/items/5
        [HttpGet("{num}")]
        public IEnumerable<string> Get(int num)
        {
            return GetLatestItems(5);
        }       

        // GET: api/items/GetLatestItems
        [HttpGet("GetLatestItems")]
        public IEnumerable<string> GetLatestItems()
        {
            return GetLatestItems(5);
        }

        // GET api/items/GetLatestItems/5
        [HttpGet("GetLatestItems/{num}")]
        public IEnumerable<string> GetLatestItems(int num)
        {
            return new string[] { "test", "test2" };
        }

        // POST: /api/items/PostSomething
        [HttpPost("PostSomething")]
        public IActionResult Post([FromBody]string someData)
        {
            return Content("OK, got it!");
        }
    }
}

This controller will handle the following requests:

 [GET] api/items
 [GET] api/items/5
 [GET] api/items/GetLatestItems
 [GET] api/items/GetLatestItems/5
 [POST] api/items/PostSomething

Also notice that if you use the two approaches togheter, Attribute-based routes (when defined) would override Convention-based ones, and both of them would override the default routes defined by UseMvc().

For more info, you can also read the following post on my blog.

you can initialize it to ' ' instead. Also, the reason that you received an error -1 being too many characters is because it is treating '-' and 1 as separate.

For me I do this to find,

let url = URL(string: urlString)
URLSession.shared.dataTask(with: url!) { (data, response, error) in ...}

Can't use

"let url = NSURL(string: urlString)

Using Blob as a source for an img:

template:

<img [src]="url">

component:

 public url : SafeResourceUrl;

 constructor(private http: HttpClient, private sanitizer: DomSanitizer) {
   this.getImage('/api/image.jpg').subscribe(x => this.url = x)
 }

 public getImage(url: string): Observable<SafeResourceUrl> {
   return this.http
     .get(url, { responseType: 'blob' })
     .pipe(
       map(x => {
         const urlToBlob = window.URL.createObjectURL(x) // get a URL for the blob
         return this.sanitizer.bypassSecurityTrustResourceUrl(urlToBlob); // tell Anuglar to trust this value
       }),
     );
 }

One more thing to check: if you've set up HTTPS access before setting up PHP -- I used certbot -- you'll need to make the changes in /etc/nginx/sites-available/default twice because there will be two server blocks (one listening on port 80 and one listening on port 443).

(I was setting up this server primarily for email and didn't have any use for PHP when I first installed nginx just as a way to run certbot more easily.)

There IS A POINT in introducing MAX_FILE_SIZE client side hidden form field.

php.ini can limit uploaded file size. So, while your script honors the limit imposed by php.ini, different HTML forms can further limit an uploaded file size. So, when uploading video, form may limit* maximum size to 10MB, and while uploading photos, forms may put a limit of just 1mb. And at the same time, the maximum limit can be set in php.ini to suppose 10mb to allow all this.

Although this is not a fool proof way of telling the server what to do, yet it can be helpful.

• HTML does'nt limit anything. It just forwards the server all form variable including MAX_FILE_SIZE and its value.

Hope it helped someone.

You could use a colormap such as HSV to generate a set of colors. For example:

cc=hsv(12);
figure; 
hold on;
for i=1:12
    plot([0 1],[0 i],'color',cc(i,:));
end

MATLAB has 13 different named colormaps ('doc colormap' lists them all).

Another option for plotting lines in different colors is to use the LineStyleOrder property; see Defining the Color of Lines for Plotting in the MATLAB documentation for more information.

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

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

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

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

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

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });

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

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

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

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

    return bitmaps;
}

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

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

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

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

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

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

Table from which you are taking data is 'LEFT'.
Table you are joining is 'RIGHT'.
LEFT JOIN: Take all items from left table AND (only) matching items from right table.
RIGHT JOIN: Take all items from right table AND (only) matching items from left table.
So:

Select * from Table1 left join Table2 on Table1.id = Table2.id  

gives:

Id     Name       
-------------  
1      A          
2      B      

but:

Select * from Table1 right join Table2 on Table1.id = Table2.id

gives:

Id     Name       
-------------  
1      A          
2      B   
3      C  

you were right joining table with less rows on table with more rows
AND
again, left joining table with less rows on table with more rows
Try:

 If Table1.Rows.Count > Table2.Rows.Count Then  
    ' Left Join  
 Else  
    ' Right Join  
 End If  

NaN is the only value in JS which is not equals to itself so we can use this information in our favour

const x = NaN;
let y = x!=x && 0; 
y = Number.isNaN(x) && 0

We can also use Number.isNaN instead of isNaN function as latter coerces its argument to number

isNaN('string')        // true which is incorrect because 'string'=='string'
Number.isNaN('string') // false 

sudo is used for Linux. It looks like you are running this in Windows.

You could build your own replace function using strstr to find the substrings and strncpy to copy in parts to a new buffer.

Unless what you want to replace_with is the same length as what you you want to replace, then it's probably best to use a new buffer to copy the new string to.

Try this:

alerts.splice(0,0,{"app":"goodbyeworld","message":"cya"});

Works pretty well, it'll add it to the start of the array.

        }

        if self.respondsToSelector(Selector("setLayoutMargins:")) {
            self.layoutMargins = UIEdgeInsetsZero
        }
    }
} 

Now you can use in your cellForRowAtIndex

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
            cell.removeMargins()//To remove seprator inset 
}

First, you gotta put your font as either a .otf or .ttf somewhere on your server.

Then use CSS to declare the new font family like this:

@font-face {
    font-family: MyFont;
    src: url('pathway/myfont.otf'); 
    }

If you link your document to the CSS file that you declared your font family in, you can use that font just like any other font.

You are comparing a jQuery object (jQuery('input:first')) to strings (the elements of the array).
Change the code in order to compare the input's value (wich is a string) to the array elements:

if (jQuery.inArray(jQuery("input:first").val(), ar) != -1)

The inArray method returns -1 if the element wasn't found in the array, so as your bonus answer to how to determine if an element is not in an array, use this :

if(jQuery.inArray(el,arr) == -1){
    // the element is not in the array
};

I'm answering this question
What would be the equivalent for \p{Lu} or \p{Ll} in regExp for js?
since it was marked as an exact duplicate of the current old question.

Querying the UCD Database of Unicode 12, \p{Lu} generates 1,788 code points.

Converting to UTF-16 yields the class construct equivalency.
It's only a 4k character string and is easily doable in any regex engines.

Note that a regex implementation of \p{Lu} or \p{Pl} actually calls a
non standard function to test the value.

The character classes shown here are done differently and are linear, standard
and pretty slow, when jammed into mostly a single class.

Some insight on how a Regex engine (in general) implements Unicode Property Classes:

Examine these performance characteristics between the property
and the class block (like above)

Regex1:  LONG CLASS 
< none >
Completed iterations:   50  /  50     ( x 1 )
Matches found per iteration:   1788
Elapsed Time:    0.73 s,   727.58 ms,   727584 µs
Matches per sec:   122,872


Regex2:   \p{Lu}
Options:  < ICU - none >
Completed iterations:   50  /  50     ( x 1 )
Matches found per iteration:   1788
Elapsed Time:    0.07 s,   65.32 ms,   65323 µs
Matches per sec:   1,368,583

Wow what a difference !!

Lets see how Properties might be implemented

Array of Pointers [ 10FFFF ] where each index is is a Code Point

• Each pointer in the Array is to a structure of classification.

  • A Classification structure contains fixed field elemets.
    Some are NULL and do not pertain.
    Some contain category classifications.

    Example : General Category
    This is a bitmapped element that uses 17 out of 64 bits.
    Whatever this Code Point supports has bit(s) set as a mask.

    -Close_Punctuation
    -Connector_Punctuation
    -Control
    -Currency_Symbol
    -Dash_Punctuation
    -Decimal_Number
    -Enclosing_Mark
    -Final_Punctuation
    -Format
    -Initial_Punctuation
    -Letter_Number
    -Line_Separator
    -Lowercase_Letter
    -Math_Symbol
    -Modifier_Letter
    -Modifier_Symbol
    -Nonspacing_Mark
    -Open_Punctuation
    -Other_Letter
    -Other_Number
    -Other_Punctuation
    -Other_Symbol
    -Paragraph_Separator
    -Private_Use
    -Space_Separator
    -Spacing_Mark
    -Surrogate
    -Titlecase_Letter
    -Unassigned
    -Uppercase_Letter

When a regex is parsed with something like this \p{Lu} it
is translated directly into

• Classification Structure element offset : General Category
• A check of that element for bit item : Uppercase_Letter

Another example, when a regex is parsed with punctuation property \p{P} it
is translated into

• Classification Structure element offset : General Category

• A check of that element for any of these items bits, which are joined into a mask :

  -Close_Punctuation
  -Connector_Punctuation
  -Dash_Punctuation
  -Final_Punctuation
  -Initial_Punctuation
  -Open_Punctuation
  -Other_Punctuation

The offset and bit or bit(mask) are stored as a regex step for that property.

The lookup table is created once for all Unicode Code Points using this array.

When a character is checked, it is as simple as using the CP as an index into this array and checking the Classification Structure's specific element for that bit(mask).

This structure is expandable and indirect to provide much more complex look ups. This is just a simple example.

Compare that direct lookup with a character class search :

All classes are a linear list of items searched from left to right.
In this comparison, given our target string contains only the complete Upper Case Unicode Letters only, the law of averages would predict that half of the items in the class would have to be ranged checked to find a match.

This is a huge disadvantage in performance.

However, if the lookup tables are not there or are not up to date with the latest Unicode release (12 as of this date)
then this would be the only way.

In fact, it is mostly the only way to get the complete Emoji
characters as there is no specific property (or reasoning) to their assignment.

If you get an error indicating that you must call makeText, the following code will fix it:

Toast toast= Toast.makeText(getApplicationContext(), 
"Your string here", Toast.LENGTH_SHORT);  
toast.setGravity(Gravity.TOP|Gravity.CENTER_HORIZONTAL, 0, 0);
toast.show();

One way would be to convert both strings to upper or lower:

test $(echo "string" | /bin/tr '[:upper:]' '[:lower:]') = $(echo "String" | /bin/tr '[:upper:]' '[:lower:]') && echo same || echo different

Another way would be to use grep:

echo "string" | grep -qi '^String$' && echo same || echo different

Simply run :

git checkout -b branch-name <commit>

For example :

git checkout -b import/january-2019 1d0fa4fa9ea961182114b63976482e634a8067b8

The checkout command with the parameter -b will create a new branch AND it will switch you over to it

You need to encode the URI to replace illegal characters with legal encoded characters. If you first make a URL (so you don't have to do the parsing yourself) and then make a URI using the five-argument constructor, then the constructor will do the encoding for you.

import java.net.*;

public class Test {
  public static void main(String[] args) {
    String myURL = "http://finance.yahoo.com/q/h?s=^IXIC";
    try {
      URL url = new URL(myURL);
      String nullFragment = null;
      URI uri = new URI(url.getProtocol(), url.getHost(), url.getPath(), url.getQuery(), nullFragment);
      System.out.println("URI " + uri.toString() + " is OK");
    } catch (MalformedURLException e) {
      System.out.println("URL " + myURL + " is a malformed URL");
    } catch (URISyntaxException e) {
      System.out.println("URI " + myURL + " is a malformed URL");
    }
  }
}

To add to the above correct answer :- For my case in shell, this code worked (working on sqoop)

ROOT_PATH="path/to/the/folder"
--options-file  $ROOT_PATH/query.txt

To obtain entries whose values in the dt_mvmt column are not null we have

df.filter("dt_mvmt is not NULL")

and for entries which are null we have

df.filter("dt_mvmt is NULL")

The easiest way is to use lubridate:

library(lubridate)
prods.all$Date2 <- mdy(prods.all$Date2)

This function automatically returns objects of class POSIXct and will work with either factors or characters.

"\n" is just a line feed (Unicode U+000A). This is typically the Unix line separator.

"\r\n" is a carriage return (Unicode U+000D) followed by a line feed (Unicode U+000A). This is typically the Windows line separator.

It is because your Maven not able to find settings file. If deleting .m2 not work, try below solution

Go to your JOB configuration

than to the Build section

Add build step :- Invoke top level maven target and fill Maven version and Goal

than click on Advance button and mention settings file path as mention in image

Any of the above answers are valid, or an alternative way is to expand the table name to include the database name as well - eg:

SELECT * from us_music, de_music where `us_music.genre` = 'punk' AND `de_music.genre` = 'punk'

I was having this same issue for both Windows 8 and Windows Server 2012 configurations. I had installed the latest version of JDK Java 7 and had set my **JAVA_HOME**system env variable to the jre folder: *C:\Program Files (x86)\Java\jre7* I also added the bin folder to my **Path** system env variable: *%JAVA_HOME%\bin*

But I was still having problems with double clicking the executable jar files. I found another system env variable OPENDS_JAVA_ARGS that can be used to set the optional properties for javaw.exe. So I added this variable and set it to: -jar

Now I am able to run the executable jar files when double clicking them.

Try This

;With Tab AS (SELECT DISTINCT Email FROM  Products)
SELECT Email,ROW_NUMBER() OVER(ORDER BY Email ASC) AS  Id FROM Tab
ORDER BY Email ASC

You can use boost::posix_time::time_duration to get the time range. E.g like this

boost::posix_time::time_duration diff = tick - now;
diff.total_milliseconds();

And to get a higher resolution you can change the clock you are using. For example to the boost::posix_time::microsec_clock, though this can be OS dependent. On Windows, for example, boost::posix_time::microsecond_clock has milisecond resolution, not microsecond.

An example which is a little dependent on the hardware.

int main(int argc, char* argv[])
{
    boost::posix_time::ptime t1 = boost::posix_time::second_clock::local_time();
    boost::this_thread::sleep(boost::posix_time::millisec(500));
    boost::posix_time::ptime t2 = boost::posix_time::second_clock::local_time();
    boost::posix_time::time_duration diff = t2 - t1;
    std::cout << diff.total_milliseconds() << std::endl;

    boost::posix_time::ptime mst1 = boost::posix_time::microsec_clock::local_time();
    boost::this_thread::sleep(boost::posix_time::millisec(500));
    boost::posix_time::ptime mst2 = boost::posix_time::microsec_clock::local_time();
    boost::posix_time::time_duration msdiff = mst2 - mst1;
    std::cout << msdiff.total_milliseconds() << std::endl;
    return 0;
}

On my win7 machine. The first out is either 0 or 1000. Second resolution. The second one is nearly always 500, because of the higher resolution of the clock. I hope that help a little.

I wanted to change the column value in a specific row. Thanks to above answers and after some serching able to come up with below,

var dataTable = $("#yourtableid");
var rowNumber = 0;  
var columnNumber= 2;   
dataTable[0].rows[rowNumber].cells[columnNumber].innerHTML = 'New Content';

Use calc:

.leftSide {_x000D_
  float: left;_x000D_
  width: 50px;_x000D_
  background-color: green;_x000D_
}_x000D_
.rightSide {_x000D_
  float: left;_x000D_
  width: calc(100% - 50px);_x000D_
  background-color: red;_x000D_
}

<div style="width:200px">_x000D_
  <div class="leftSide">a</div>_x000D_
  <div class="rightSide">b</div>_x000D_
</div>

The problem with this is that all widths must be explicitly defined, either as a value(px and em work fine), or as a percent of something explicitly defined itself.

I could get solution for such a similar problem with addition of a simple line

HttpURLConnection hConn = (HttpURLConnection) url.openConnection();
hConn.setRequestMethod("HEAD");

My requirement was to know the response code and for that just getting the meta-information was sufficient, instead of getting the complete response body.

Default request method is GET and that was taking lot of time to return, finally throwing me SocketTimeoutException. The response was pretty fast when I set the Request Method to HEAD.

Note: Due to changes made to jQuery 1.9 and jQuery UI, this answer is no longer the correct one. Please see @stankovski's answer below.

You need to find the tab's index first (which is just its position in a list) and then specifically select the tab using jQuery UI's provided select event (tabs->select).

var index = $('#tabs ul').index($('#tabId'));
$('#tabs ul').tabs('select', index);

Update: BTW - I do realize that this is (ultimately) still selecting by index. But, it doesn't require that you know the specific position of the tabs (particularly when they are dynamically generated as asked in the question).

What are the steps for that? where is AppCompat located?

Download the support library here:

http://developer.android.com/tools/support-library/setup.html

If you are using Eclipse:

Go to the tabs at the top and select ( Windows -> Android SDK Manager ). Under the 'extras' section, check 'Android Support Library' and check it for installation.

After that, the AppCompat library can be found at:

android-sdk/extras/android/support/v7/appcompat

You need to reference this AppCompat library in your Android project.

Import the library into Eclipse.

1. Right click on your Android project.
2. Select properties.
3. Click 'add...' at the bottom to add a library.
4. Select the support library
5. Clean and rebuild your project.

TL;DR

1) When you’re using a Factory you create an object, add properties to it, then return that same object. When you pass this factory into your controller, those properties on the object will now be available in that controller through your factory.

app.controller('myFactoryCtrl', function($scope, myFactory){
  $scope.artist = myFactory.getArtist();
});

app.factory('myFactory', function(){
  var _artist = 'Shakira';
  var service = {};

  service.getArtist = function(){
    return _artist;
  }

  return service;
});

2) When you’re using Service, Angular instantiates it behind the scenes with the ‘new’ keyword. Because of that, you’ll add properties to ‘this’ and the service will return ‘this’. When you pass the service into your controller, those properties on ‘this’ will now be available on that controller through your service.

app.controller('myServiceCtrl', function($scope, myService){
  $scope.artist = myService.getArtist();
});

app.service('myService', function(){
  var _artist = 'Nelly';
  this.getArtist = function(){
    return _artist;
  }
});

Non TL;DR

1) Factory
Factories are the most popular way to create and configure a service. There’s really not much more than what the TL;DR said. You just create an object, add properties to it, then return that same object. Then when you pass the factory into your controller, those properties on the object will now be available in that controller through your factory. A more extensive example is below.

app.factory('myFactory', function(){
  var service = {};
  return service;
});

Now whatever properties we attach to ‘service’ will be available to us when we pass ‘myFactory’ into our controller.

Now let’s add some ‘private’ variables to our callback function. These won’t be directly accessible from the controller, but we will eventually set up some getter/setter methods on ‘service’ to be able to alter these ‘private’ variables when needed.

app.factory('myFactory', function($http, $q){
  var service = {};
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
   _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK';
    return _finalUrl
  }

  return service;
});

Here you’ll notice we’re not attaching those variables/function to ‘service’. We’re simply creating them in order to either use or modify them later.

• baseUrl is the base URL that the iTunes API requires
• _artist is the artist we wish to lookup
• _finalUrl is the final and fully built URL to which we’ll make the call to iTunes makeUrl is a function that will create and return our iTunes friendly URL.

Now that our helper/private variables and function are in place, let’s add some properties to the ‘service’ object. Whatever we put on ‘service’ we’ll be able to directly use in whichever controller we pass ‘myFactory’ into.

We are going to create setArtist and getArtist methods that simply return or set the artist. We are also going to create a method that will call the iTunes API with our created URL. This method is going to return a promise that will fulfill once the data has come back from the iTunes API. If you haven’t had much experience using promises in Angular, I highly recommend doing a deep dive on them.

Below setArtist accepts an artist and allows you to set the artist. getArtist returns the artist callItunes first calls makeUrl() in order to build the URL we’ll use with our $http request. Then it sets up a promise object, makes an $http request with our final url, then because $http returns a promise, we are able to call .success or .error after our request. We then resolve our promise with the iTunes data, or we reject it with a message saying ‘There was an error’.

app.factory('myFactory', function($http, $q){
  var service = {};
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
    _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK'
    return _finalUrl;
  }

  service.setArtist = function(artist){
    _artist = artist;
  }

  service.getArtist = function(){
    return _artist;
  }

  service.callItunes = function(){
    makeUrl();
    var deferred = $q.defer();
    $http({
      method: 'JSONP',
      url: _finalUrl
    }).success(function(data){
      deferred.resolve(data);
    }).error(function(){
      deferred.reject('There was an error')
    })
    return deferred.promise;
  }

  return service;
});

Now our factory is complete. We are now able to inject ‘myFactory’ into any controller and we’ll then be able to call our methods that we attached to our service object (setArtist, getArtist, and callItunes).

app.controller('myFactoryCtrl', function($scope, myFactory){
  $scope.data = {};
  $scope.updateArtist = function(){
    myFactory.setArtist($scope.data.artist);
  };

  $scope.submitArtist = function(){
    myFactory.callItunes()
      .then(function(data){
        $scope.data.artistData = data;
      }, function(data){
        alert(data);
      })
  }
});

In the controller above we’re injecting in the ‘myFactory’ service. We then set properties on our $scope object that are coming from data from ‘myFactory’. The only tricky code above is if you’ve never dealt with promises before. Because callItunes is returning a promise, we are able to use the .then() method and only set $scope.data.artistData once our promise is fulfilled with the iTunes data. You’ll notice our controller is very ‘thin’. All of our logic and persistent data is located in our service, not in our controller.

2) Service
Perhaps the biggest thing to know when dealing with creating a Service is that that it’s instantiated with the ‘new’ keyword. For you JavaScript gurus this should give you a big hint into the nature of the code. For those of you with a limited background in JavaScript or for those who aren’t too familiar with what the ‘new’ keyword actually does, let’s review some JavaScript fundamentals that will eventually help us in understanding the nature of a Service.

To really see the changes that occur when you invoke a function with the ‘new’ keyword, let’s create a function and invoke it with the ‘new’ keyword, then let’s show what the interpreter does when it sees the ‘new’ keyword. The end results will both be the same.

First let’s create our Constructor.

var Person = function(name, age){
  this.name = name;
  this.age = age;
}

This is a typical JavaScript constructor function. Now whenever we invoke the Person function using the ‘new’ keyword, ‘this’ will be bound to the newly created object.

Now let’s add a method onto our Person’s prototype so it will be available on every instance of our Person ‘class’.

Person.prototype.sayName = function(){
  alert('My name is ' + this.name);
}

Now, because we put the sayName function on the prototype, every instance of Person will be able to call the sayName function in order alert that instance’s name.

Now that we have our Person constructor function and our sayName function on its prototype, let’s actually create an instance of Person then call the sayName function.

var tyler = new Person('Tyler', 23);
tyler.sayName(); //alerts 'My name is Tyler'

So all together the code for creating a Person constructor, adding a function to it’s prototype, creating a Person instance, and then calling the function on its prototype looks like this.

var Person = function(name, age){
  this.name = name;
  this.age = age;
}
Person.prototype.sayName = function(){
  alert('My name is ' + this.name);
}
var tyler = new Person('Tyler', 23);
tyler.sayName(); //alerts 'My name is Tyler'

Now let’s look at what actually is happening when you use the ‘new’ keyword in JavaScript. First thing you should notice is that after using ‘new’ in our example, we’re able to call a method (sayName) on ‘tyler’ just as if it were an object - that’s because it is. So first, we know that our Person constructor is returning an object, whether we can see that in the code or not. Second, we know that because our sayName function is located on the prototype and not directly on the Person instance, the object that the Person function is returning must be delegating to its prototype on failed lookups. In more simple terms, when we call tyler.sayName() the interpreter says “OK, I’m going to look on the ‘tyler’ object we just created, locate the sayName function, then call it. Wait a minute, I don’t see it here - all I see is name and age, let me check the prototype. Yup, looks like it’s on the prototype, let me call it.”.

Below is code for how you can think about what the ‘new’ keyword is actually doing in JavaScript. It’s basically a code example of the above paragraph. I’ve put the ‘interpreter view’ or the way the interpreter sees the code inside of notes.

var Person = function(name, age){
  //The line below this creates an obj object that will delegate to the person's prototype on failed lookups.
  //var obj = Object.create(Person.prototype);

  //The line directly below this sets 'this' to the newly created object
  //this = obj;

  this.name = name;
  this.age = age;

  //return this;
}

Now having this knowledge of what the ‘new’ keyword really does in JavaScript, creating a Service in Angular should be easier to understand.

The biggest thing to understand when creating a Service is knowing that Services are instantiated with the ‘new’ keyword. Combining that knowledge with our examples above, you should now recognize that you’ll be attaching your properties and methods directly to ‘this’ which will then be returned from the Service itself. Let’s take a look at this in action.

Unlike what we originally did with the Factory example, we don’t need to create an object then return that object because, like mentioned many times before, we used the ‘new’ keyword so the interpreter will create that object, have it delegate to it’s prototype, then return it for us without us having to do the work.

First things first, let’s create our ‘private’ and helper function. This should look very familiar since we did the exact same thing with our factory. I won’t explain what each line does here because I did that in the factory example, if you’re confused, re-read the factory example.

app.service('myService', function($http, $q){
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
    _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK'
    return _finalUrl;
  }
});

Now, we’ll attach all of our methods that will be available in our controller to ‘this’.

app.service('myService', function($http, $q){
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
    _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK'
    return _finalUrl;
  }

  this.setArtist = function(artist){
    _artist = artist;
  }

  this.getArtist = function(){
    return _artist;
  }

  this.callItunes = function(){
    makeUrl();
    var deferred = $q.defer();
    $http({
      method: 'JSONP',
      url: _finalUrl
    }).success(function(data){
      deferred.resolve(data);
    }).error(function(){
      deferred.reject('There was an error')
    })
    return deferred.promise;
  }

});

Now just like in our factory, setArtist, getArtist, and callItunes will be available in whichever controller we pass myService into. Here’s the myService controller (which is almost exactly the same as our factory controller).

app.controller('myServiceCtrl', function($scope, myService){
  $scope.data = {};
  $scope.updateArtist = function(){
    myService.setArtist($scope.data.artist);
  };

  $scope.submitArtist = function(){
    myService.callItunes()
      .then(function(data){
        $scope.data.artistData = data;
      }, function(data){
        alert(data);
      })
  }
});

Like I mentioned before, once you really understand what ‘new’ does, Services are almost identical to factories in Angular.

Unless you're worried about performance, use string streams:

#include <sstream>
//..

std::ostringstream ss;
ss << myFloat;
std::string s(ss.str());

If you're okay with Boost, lexical_cast<> is a convenient alternative:

std::string s = boost::lexical_cast<std::string>(myFloat);

Efficient alternatives are e.g. FastFormat or simply the C-style functions.

Capturing and grouping

Capturing group (pattern) creates a group that has capturing property.

A related one that you might often see (and use) is (?:pattern), which creates a group without capturing property, hence named non-capturing group.

A group is usually used when you need to repeat a sequence of patterns, e.g. (\.\w+)+, or to specify where alternation should take effect, e.g. ^(0*1|1*0)$ (^, then 0*1 or 1*0, then $) versus ^0*1|1*0$ (^0*1 or 1*0$).

A capturing group, apart from grouping, will also record the text matched by the pattern inside the capturing group (pattern). Using your example, (.*):, .* matches ABC and : matches :, and since .* is inside capturing group (.*), the text ABC is recorded for the capturing group 1.

Group number

The whole pattern is defined to be group number 0.

Any capturing group in the pattern start indexing from 1. The indices are defined by the order of the opening parentheses of the capturing groups. As an example, here are all 5 capturing groups in the below pattern:

(group)(?:non-capturing-group)(g(?:ro|u)p( (nested)inside)(another)group)(?=assertion)
|     |                       |          | |      |      ||       |     |
1-----1                       |          | 4------4      |5-------5     |
                              |          3---------------3              |
                              2-----------------------------------------2

The group numbers are used in back-reference \n in pattern and $n in replacement string.

^{In other regex flavors (PCRE, Perl), they can also be used in sub-routine calls.}

You can access the text matched by certain group with Matcher.group(int group). The group numbers can be identified with the rule stated above.

^{In some regex flavors (PCRE, Perl), there is a branch reset feature which allows you to use the same number for capturing groups in different branches of alternation.}

Group name

From Java 7, you can define a named capturing group (?<name>pattern), and you can access the content matched with Matcher.group(String name). The regex is longer, but the code is more meaningful, since it indicates what you are trying to match or extract with the regex.

The group names are used in back-reference \k<name> in pattern and ${name} in replacement string.

Named capturing groups are still numbered with the same numbering scheme, so they can also be accessed via Matcher.group(int group).

Internally, Java's implementation just maps from the name to the group number. Therefore, you cannot use the same name for 2 different capturing groups.

My answer is intended for comment though but since i havent got enough reputation, i think it will still be relevant as an answer and help some one.

I find datatable in library DT robust to handle rownames, and columnames

Library DT
datatable(df, rownames = FALSE)  # no row names 

refer to https://rstudio.github.io/DT/ for usage scenarios

Checkout the following article on MSDN about examples of the N format. This is also covered in the Standard Numeric Format Strings article.

Relevant excerpts:

//       Formatting of 1054.32179:
//          N:                     1,054.32 
//          N0:                    1,054 
//          N1:                    1,054.3 
//          N2:                    1,054.32 
//          N3:                    1,054.322 

When precision specifier controls the number of fractional digits in the result string, the result string reflects a number that is rounded to a representable result nearest to the infinitely precise result. If there are two equally near representable results:

• On the .NET Framework and .NET Core up to .NET Core 2.0, the runtime selects the result with the greater least significant digit (that is, using MidpointRounding.AwayFromZero).
• On .NET Core 2.1 and later, the runtime selects the result with an even least significant digit (that is, using MidpointRounding.ToEven).

Like this?

$string = 'FirstPart SecondPart'
$a,$b = $string.split(' ')
$a
$b

You can use a lookaround:

^(?=.*[A-Za-z0-9])[A-Za-z0-9 _]*$

It will check ahead that the string has a letter or number, if it does it will check that the rest of the chars meet your requirements. This can probably be improved upon, but it seems to work with my tests.

UPDATE:

Adding modifications suggested by Chris Lutz:

^(?=.*[^\W_])[\w ]*$/

Sigh. Back in the 70s I was the "system programmer" (sysadmin) for an IBM 370 system, and my employer was a member of the IBM users group SHARE. It would sometimes happen thatsomebody submitted an APAR (bug report) on some unexpected behavior of some CMS command, and IBM would respond NOTABUG: the command does what it was designed to do (and what the documentation says).

SHARE came up with a counter to this: BAD -- Broken As Designed. I think this might apply to this implementation of equals for arrays.

There's nothing wrong with the implementation of Object.equals. Object has no data members, so there is nothing to compare. Two "Object"s are equal if and only if they are, in fact, the same Object (internally, the same address and length).

But that logic doesn't apply to arrays. Arrays have data, and you expect comparison (via equals) to compare the data. Ideally, the way Arrays.deepEquals does, but at least the way Arrays.equals does (shallow comparison of the elements).

So the problem is that array (as a built-in object) does not override Object.equals. String (as a named class) does override Object.equals and give the result you expect.

Other answers given are correct: [...].equals([....]) simply compares the pointers and not the contents. Maybe someday somebody will correct this. Or maybe not: how many existing programs would break if [...].equals actually compared the elements? Not many, I suspect, but more than zero.

I solved the same issue by following steps:

Check the angular version: Using command: ng version My angular version is: Angular CLI: 7.3.10

After that I have support version of ngx bootstrap from the link: https://www.npmjs.com/package/ngx-bootstrap

In package.json file update the version: "bootstrap": "^4.5.3", "@ng-bootstrap/ng-bootstrap": "^4.2.2",

Now after updating package.json, use the command npm update

After this use command ng serve and my error got resolved

The above solutions did not work for me, but this code from Select2's own website did:

$('select').val('US'); // Select the option with a value of 'US'
$('select').trigger('change'); // Notify any JS components that the value changed

Hope this helps for anyone who is struggling, like I was.

The problem is because you haven't set JDK version properly.You should use jdk 7 for major number 51. Like this:

JAVA_HOME=/usr/java/jdk1.7.0_79

Per the MSDN documentation for sys.database_permissions, this query lists all permissions explicitly granted or denied to principals in the database you're connected to:

SELECT DISTINCT pr.principal_id, pr.name, pr.type_desc, 
    pr.authentication_type_desc, pe.state_desc, pe.permission_name
FROM sys.database_principals AS pr
JOIN sys.database_permissions AS pe
    ON pe.grantee_principal_id = pr.principal_id;

Per Managing Databases and Logins in Azure SQL Database, the loginmanager and dbmanager roles are the two server-level security roles available in Azure SQL Database. The loginmanager role has permission to create logins, and the dbmanager role has permission to create databases. You can view which users belong to these roles by using the query you have above against the master database. You can also determine the role memberships of users on each of your user databases by using the same query (minus the filter predicate) while connected to them.

• First create the menu layouts in the your Activity layout xml file. For e.g. a linear layout with horizontal orientation and include a TextView for label then a Floating Action Button beside the TextView.

• Create the menu layouts as per your need and number.

• Create a Base Floating Action Button and on its click of that change the visibility of the Menu Layouts.

    android:fromAlpha="0.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="1.0" />

</set>

Closing animation of FAB Menu:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<scale
    android:duration="300"

    android:interpolator="@android:anim/linear_interpolator"

    android:fromAlpha="1.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="0.0" />
</set>

Then in my Activity I've simply used the animations above to show and hide the FAB menu :

Show Fab Menu:

  private void expandFabMenu() {

    ViewCompat.animate(binding.baseFloatingActionButton).rotation(45.0F).withLayer().setDuration(300).setInterpolator(new OvershootInterpolator(10.0F)).start();
    binding.createLayout.startAnimation(fabOpenAnimation);
    binding.shareLayout.startAnimation(fabOpenAnimation);
    binding.createFab.setClickable(true);
    binding.shareFab.setClickable(true);
    isFabMenuOpen = true;

}

Close Fab Menu:

private void collapseFabMenu() {

    ViewCompat.animate(binding.baseFloatingActionButton).rotation(0.0F).withLayer().setDuration(300).setInterpolator(new OvershootInterpolator(10.0F)).start();
    binding.createLayout.startAnimation(fabCloseAnimation);
    binding.shareLayout.startAnimation(fabCloseAnimation);
    binding.createFab.setClickable(false);
    binding.shareFab.setClickable(false);
    isFabMenuOpen = false;

}

Here is the the Activity class -

package com.app.fabmenu;

    isFabMenuOpen = false;

}


public class FabHandler {

    public void onBaseFabClick(View view) {

        if (isFabMenuOpen)
            collapseFabMenu();
        else
            expandFabMenu();


    }

    public void onCreateFabClick(View view) {

        Snackbar.make(binding.coordinatorLayout, "Create FAB tapped", Snackbar.LENGTH_SHORT).show();

    }

    public void onShareFabClick(View view) {

        Snackbar.make(binding.coordinatorLayout, "Share FAB tapped", Snackbar.LENGTH_SHORT).show();

    }


}

@Override
public void onBackPressed() {

    if (isFabMenuOpen)
        collapseFabMenu();
    else
        super.onBackPressed();
}
}

Here are the screenshots

cd /driveName driveName:\pathNamw

On Android use:

android.text.TextUtils.join(",", ids);

When doing recursive replacement, the path and filename need to be included:

Get-ChildItem -Recurse | ForEach {  (Get-Content $_.PSPath | 
ForEach {$ -creplace "old", "new"}) | Set-Content $_.PSPath }

This wil replace all "old" with "new" case-sensitive in all the files of your folders of your current directory.

Here's a new one from Dinosaur Comics:

ladies and gentlemen: mr. stack overflow! http://www.qwantz.com/comics/comic2-82.png

This would be work very fine

<a href="<%:Url.Action("Edit","Account",new {  id=item.UserId }) %>"><img src="../../Content/ThemeNew/images/edit_notes_delete11.png" alt="Edit" width="25px" height="25px" /></a>

With jQuery, you can do a single-line operation like this:

Example: http://jsfiddle.net/HWKQY/

y.splice( $.inArray(removeItem, y), 1 );

Uses the native .splice() and jQuery's $.inArray().

If you set Vim to use the system clipboard (:set clipboard=unnamed), then any text you copy in Vim can be pasted using Shift + Insert. Shift + Insert is simply an OS-wide paste key-combination (Ctrl + Insert is the corresponding 'copy').

Combining solutions above when using express request:

let url=url.parse(req.originalUrl);
let page = url.parse(uri).path?url.parse(uri).path.match('^[^?]*')[0].split('/').slice(1)[0] : '';

this will handle all cases like

localhost/page
localhost:3000/page/
/page?item_id=1
localhost:3000/
localhost/

etc. Some examples:

> urls
[ 'http://localhost/page',
  'http://localhost:3000/page/',
  'http://localhost/page?item_id=1',
  'http://localhost/',
  'http://localhost:3000/',
  'http://localhost/',
  'http://localhost:3000/page#item_id=2',
  'http://localhost:3000/page?item_id=2#3',
  'http://localhost',
  'http://localhost:3000' ]
> urls.map(uri => url.parse(uri).path?url.parse(uri).path.match('^[^?]*')[0].split('/').slice(1)[0] : '' )
[ 'page', 'page', 'page', '', '', '', 'page', 'page', '', '' ]

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

Code snippet

Since this answer got very much attention, here is a nice configurable snippet I came up with:

(function (exports) {
    function valOrFunction(val, ctx, args) {
        if (typeof val == "function") {
            return val.apply(ctx, args);
        } else {
            return val;
        }
    }

    function InvalidInputHelper(input, options) {
        input.setCustomValidity(valOrFunction(options.defaultText, window, [input]));

        function changeOrInput() {
            if (input.value == "") {
                input.setCustomValidity(valOrFunction(options.emptyText, window, [input]));
            } else {
                input.setCustomValidity("");
            }
        }

        function invalid() {
            if (input.value == "") {
                input.setCustomValidity(valOrFunction(options.emptyText, window, [input]));
            } else {
               input.setCustomValidity(valOrFunction(options.invalidText, window, [input]));
            }
        }

        input.addEventListener("change", changeOrInput);
        input.addEventListener("input", changeOrInput);
        input.addEventListener("invalid", invalid);
    }
    exports.InvalidInputHelper = InvalidInputHelper;
})(window);

Usage

→ jsFiddle

<input id="email" type="email" required="required" />

InvalidInputHelper(document.getElementById("email"), {
  defaultText: "Please enter an email address!",

  emptyText: "Please enter an email address!",

  invalidText: function (input) {
    return 'The email address "' + input.value + '" is invalid!';
  }
});

More details

• defaultText is displayed initially
• emptyText is displayed when the input is empty (was cleared)
• invalidText is displayed when the input is marked as invalid by the browser (for example when it's not a valid email address)

You can either assign a string or a function to each of the three properties.
If you assign a function, it can accept a reference to the input element (DOM node) and it must return a string which is then displayed as the error message.

• Opera 31.0

Old answer

You can see the old revision here: https://stackoverflow.com/revisions/16069817/6

From the screenshot I can see that you want to pass "user" and "password" values to the service. You have send the parameter values in the request header part which is wrong. The values are sent in the request body and not in the request header. Also your syntax is wrong. Correct syntax is: {"user":"user_val","password":"password_val"}. Also check what is the the content type. It should match with the content type you have set to your service.

MultiBinding friendly version...

private void ComboBox_Loaded(object sender, RoutedEventArgs e)
{
    BindingOperations.GetBindingExpressionBase((ComboBox)sender, ComboBox.ItemsSourceProperty).UpdateTarget();
}

In Python 3 you can overwrite print function with default set to flush = True

def print(*objects, sep=' ', end='\n', file=sys.stdout, flush=True):
    __builtins__.print(*objects, sep=sep, end=end, file=file, flush=flush)

You most likely want to examine the documentation for T-SQL's CAST and CONVERT functions, located in the documentation here: http://msdn.microsoft.com/en-US/library/ms187928(v=SQL.90).aspx

You will then use one of those functions in your T-SQL query to convert the [idate] column from the database into the datetime format of your liking in the output.

getTitle is a function, so you need to put () after it.

string t = obj.getTitle();

I think you meant something like this: JSON Visualization

Don't know if you might use it, but you might ask the author.

Easy and simple way to quit from the application

Intent homeIntent = new Intent(Intent.ACTION_MAIN);
homeIntent.addCategory(Intent.CATEGORY_HOME);
homeIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

Here is how I show hover text using JavaScript tooltip:

<script language="JavaScript" type="text/javascript" src="javascript/wz_tooltip.js"></script>

<div class="curhand" onmouseover="this.T_WIDTH=125; return escape('Welcome')">Are you New Here?</div>

If I'm not mistaken, the OP was asking (although later accepted a .js solution) whether Google's embedded PDF display server will display a PDF on his own website.

So, one and a half years later: yes, it will.

See http://googlesystem.blogspot.ca/2009/09/embeddable-google-document-viewer.html. Also, see https://docs.google.com/viewer, and plug in the URL of the file you want to display.

Edit: Re-reading, OP was asking for solutions that don't use iFrames. I don't think that's possible with Google's viewer.

''Alastair, you can use this lib and tool; DefiantJS. It enables XPath queries on JSON structures and you can test and validate this XPath:

//data[category="Politician"]

DefiantJS extends the global object with the method "search", which in turn returns an array with the matches. In Javascript, it'll look like this:

var person = JSON.search(json_data, "//people[category='Politician']");
console.log( person[0].name );
// Barack Obama

Made a category like mxcl, but this is slightly faster.

My testing shows ~15% improvement (I could be wrong, feel free to compare the two yourself).

Basically I take the portion of the array thats in front of the object and the portion behind and combine them. Thus excluding the element.

- (NSArray *)prefix_arrayByRemovingObject:(id)object 
{
    if (!object) {
        return self;
    }

    NSUInteger indexOfObject = [self indexOfObject:object];
    NSArray *firstSubArray = [self subarrayWithRange:NSMakeRange(0, indexOfObject)];
    NSArray *secondSubArray = [self subarrayWithRange:NSMakeRange(indexOfObject + 1, self.count - indexOfObject - 1)];
    NSArray *newArray = [firstSubArray arrayByAddingObjectsFromArray:secondSubArray];

    return newArray;
}

One liner (Linux)

unzip -p mylib.jar META-INF/MANIFEST.MF

This prints the content of MANIFEST.MF file to stdout (hopefully there is one in your jar file :)

Depending on what built your package, you will find the JDK version in Created-By or Build-Jdk key.

Depending on what you're trying to do, you can either block with GetIdList().Result ( generally a bad idea, but it's hard to tell the context) or use a test framework that supports async test methods and have the test method do var results = await GetIdList();

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

Original Answer

FROM ubuntu:14.04
RUN rm /bin/sh && ln -s /bin/bash /bin/sh

This should work for every Ubuntu docker base image. I generally add this line for every Dockerfile I write.

Edit by a concerned bystander

If you want to get the effect of "use bash instead of sh throughout this entire Dockerfile", without altering and possibly damaging* the OS inside the container, you can just tell Docker your intention. That is done like so:

SHELL ["/bin/bash", "-c"]

* The possible damage is that many scripts in Linux (on a fresh Ubuntu install grep -rHInE '/bin/sh' / returns over 2700 results) expect a fully POSIX shell at /bin/sh. The bash shell isn't just POSIX plus extra builtins. There are builtins (and more) that behave entirely different than those in POSIX. I FULLY support avoiding POSIX (and the fallacy that any script that you didn't test on another shell is going to work because you think you avoided basmisms) and just using bashism. But you do that with a proper shebang in your script. Not by pulling the POSIX shell out from under the entire OS. (Unless you have time to verify all 2700 plus scripts that come with Linux plus all those in any packages you install.)

I meet the same issue on a Windows installed .NET Framework 4.0.
And I Solved this issue by installing .NET Framework 4.6.2.
Or you may download the newest package to have a try.

Where do you want to see the output?

Messages being output via Debug.Print will be displayed in the immediate window which you can open by pressing Ctrl+G.

You can also Activate the so called Immediate Window by clicking View -> Immediate Window on the VBE toolbar

In a nutshell, no.

However, there are "nice" things you can do.

1. Run a profiler trace with, say, the stored proc name
2. Add a line each proc (create a tabel of course)
   • "INSERT dbo.SPCall (What, When) VALUES (OBJECT_NAME(@@PROCID), GETDATE()"
3. Extend 2 with duration too

There are "fun" things you can do:

1. Remove it, see who calls
2. Remove rights, see who calls
3. Add RAISERROR ('Warning: pwn3d: call admin', 16, 1), see who calls
4. Add WAITFOR DELAY '00:01:00', see who calls

You get the idea. The tried-and-tested "see who calls" method of IT support.

If the reports are Reporting Services, then you can mine the RS database for the report runs if you can match code to report DataSet.

You couldn't rely on DMVs anyway because they are reset om SQL Server restart. Query cache/locks are transient and don't persist for any length of time.

Angular's $http has a cache built in. According to the docs:

cache – {boolean|Object} – A boolean value or object created with $cacheFactory to enable or disable caching of the HTTP response. See $http Caching for more information.

Boolean value

So you can set cache to true in its options:

$http.get(url, { cache: true}).success(...);

or, if you prefer the config type of call:

$http({ cache: true, url: url, method: 'GET'}).success(...);

Cache Object

You can also use a cache factory:

var cache = $cacheFactory('myCache');

$http.get(url, { cache: cache })

You can implement it yourself using $cacheFactory (especially handly when using $resource):

var cache = $cacheFactory('myCache');

var data = cache.get(someKey);

if (!data) {
   $http.get(url).success(function(result) {
      data = result;
      cache.put(someKey, data);
   });
}

You can also give your output back to the client instantly and continue processing your PHP code afterwards.

This is the method I am using for long-waiting Ajax calls which would not have any effect on client side:

ob_end_clean();
ignore_user_abort();
ob_start();
header("Connection: close");
echo json_encode($out);
header("Content-Length: " . ob_get_length());
ob_end_flush();
flush();
// execute your command here. client will not wait for response, it already has one above.

You can find the detailed explanation here: http://oytun.co/response-now-process-later

I've decided to post a new answer, because some existing answers are outdated or incomplete.

First of all: there is nothing like JUnit XML Format Specification, simply because JUnit doesn't produce any kind of XML or HTML report.

The XML report generation itself comes from the Ant JUnit task/ Maven Surefire Plugin/ Gradle (whichever you use for running your tests). The XML report format was first introduced by Ant and later adapted by Maven (and Gradle).

If somebody just needs an official XML format then:

1. There exists a schema for a maven surefire-generated XML report and it can be found here: surefire-test-report.xsd.
2. For an ant-generated XML there is a 3rd party schema available here (but it might be slightly outdated).

Hope it will help somebody.

Also if you want to create Unique constrains on multiple columns you can simply do this (following @Sampath's link)

class MyContext : DbContext
{
    public DbSet<Person> People { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Person>()
            .HasIndex(p => new { p.FirstName, p.LastName })
            .IsUnique(true);
    }
}

public class Person
{
    public int PersonId { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

Copied from IIS Modules Overview: Preconditions

i was using body-Parser that throw exception

const bodyParser = require('body-Parser')    
//Bodyparser Middleware
app.use(bodyparser.json())

intead of using

    //Bodyparser Middleware
    app.use(express.json())

this resolved my issue

Check this

UPDATE some_table SET some_field = REPLACE("Column Name/String", 'Search String', 'Replace String')

Eg with sample string:

UPDATE some_table SET some_field = REPLACE("this is test string", 'test', 'sample')

EG with Column/Field Name:

UPDATE some_table SET some_field = REPLACE(columnName, 'test', 'sample')

Or a nested List (okay, the OP was for a single column and this is for multiple columns..):

        //Base list is a list of fields, ie a data record
        //Enclosing list is then a list of those records, ie the Result set
        List<List<String>> ResultSet = new List<List<String>>();

        using (SqlConnection connection =
            new SqlConnection(connectionString))
        {
            // Create the Command and Parameter objects.
            SqlCommand command = new SqlCommand(qString, connection);

            // Create and execute the DataReader..
            connection.Open();
            SqlDataReader reader = command.ExecuteReader();
            while (reader.Read())
            {
                var rec = new List<string>();
                for (int i = 0; i <= reader.FieldCount-1; i++) //The mathematical formula for reading the next fields must be <=
                {                      
                    rec.Add(reader.GetString(i));
                }
                ResultSet.Add(rec);

            }
        }

Please make sure that you don't do any network access on UI Thread, instead do it in Async Task

The reason why your application crashes on Android versions 3.0 and above, but works fine on Android 2.x is because since HoneyComb are much stricter about abuse against the UI Thread. For example, when an Android device running HoneyComb or above detects a network access on the UI thread, a NetworkOnMainThreadException will be thrown.

See this

You can actually install both packages at the same time. For me:

conda install -c anaconda graphviz python-graphviz

did the trick.

import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"

The re.sub function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>') and replacing them with nothing ('').

The ? is used in re for non-greedy searches.

More about the re module.

I had the same problem in Google App Scripts, and solved it like the rest said, but with a little more..

function refreshGrid(entity) {
var store = window.localStorage;
var partitionKey;
if (condition) {
  return Browser.msgBox("something");
  }
}

This way you not only exit the function, but show a message saying why it stopped. Hope it helps.

You can use jackson api for the conversion

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>2.9.4</version>
</dependency>

add above maven dependency in your POM, In your main method create ObjectMapper

ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);

later we nee to add our POJO class to the mapper

String json = mapper.writeValueAsString(pojo);

there is no need to js or jquery. to stop page reloading just specify the button type as 'button'. if you dont specify the button type, browser will set it to 'reset' or 'submit' witch cause to page reload.

 <button type='button'>submit</button> 

Add it to the session, not to the request.

HttpSession session = request.getSession();
session.setAttribute("object", object);

Also, don't use scriptlets in the JSP. Use EL instead; to access object all you need is ${object}.

A primary feature of JSP technology version 2.0 is its support for an expression language (EL). An expression language makes it possible to easily access application data stored in JavaBeans components. For example, the JSP expression language allows a page author to access a bean using simple syntax such as ${name} for a simple variable or ${name.foo.bar} for a nested property.

You need to instantiate an object in order to call its member functions. The member functions need an object to operate on; they can't just be used on their own. The main() function could, for example, look like this:

int main()
{
   Name_pairs np;
   cout << "Enter names and ages. Use 0 to cancel.\n";
   while(np.test())
   {
      np.read_names();
      np.read_ages();
   }
   np.print();
   keep_window_open();
}

This is a quirk of the C grammar. A label (Cleanup:) is not allowed to appear immediately before a declaration (such as char *str ...;), only before a statement (printf(...);). In C89 this was no great difficulty because declarations could only appear at the very beginning of a block, so you could always move the label down a bit and avoid the issue. In C99 you can mix declarations and code, but you still can't put a label immediately before a declaration.

You can put a semicolon immediately after the label's colon (as suggested by Renan) to make there be an empty statement there; this is what I would do in machine-generated code. Alternatively, hoist the declaration to the top of the function:

int main (void) 
{
    char *str;
    printf("Hello ");
    goto Cleanup;
Cleanup:
    str = "World\n";
    printf("%s\n", str);
    return 0;
}

you can use the previousSibling property to iterate back through the siblings until you get back null and count how many siblings you've encountered:

var i = 0;
while( (child = child.previousSibling) != null ) 
  i++;
//at the end i will contain the index.

Please note that in languages like Java, there is a getPreviousSibling() function, however in JS this has become a property -- previousSibling.

Try delete:

models.User.query.delete()

From the docs: Returns the number of rows deleted, excluding any cascades.

They are user-defined signals, so they aren't triggered by any particular action. You can explicitly send them programmatically:

#include <signal.h>

kill(pid, SIGUSR1);

where pid is the process id of the receiving process. At the receiving end, you can register a signal handler for them:

#include <signal.h>

void my_handler(int signum)
{
    if (signum == SIGUSR1)
    {
        printf("Received SIGUSR1!\n");
    }
}

signal(SIGUSR1, my_handler);

Maybe in this way?

$('img', this)[0]

I've had this problem before, you can go to "advanced" tab of "choose a data source" page and click on "suggested types" button, and set the "number of rows" as much as you want. after that, the type and text qualified are set to the true values.

i applied the above solution and can convert my data to SQL.

Standard xargs has no good way to do it; you're better off using find -exec as someone else suggested, or wrap the sed in a script which does nothing if there are no arguments. GNU xargs has the --no-run-if-empty option, and BSD / OS X xargs has the -L option which looks like it should do something similar.

Immediately after that line try closing the response using exit or die()

header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found");
exit;

or

header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found");
die();

You would use DATEDIFF:

declare @start datetime
declare @end datetime

set @start = '2011-01-01'
set @end = '2012-01-01'

select DATEDIFF(d, @start, @end)

results = 365

so for your query:

SELECT dtCreated
    , bActive
    , dtLastPaymentAttempt
    , dtLastUpdated
    , dtLastVisit
    , DATEDIFF(d, dtCreated, dtLastUpdated) as Difference
FROM Customers
WHERE (bActive = 'true') 
    AND (dtLastUpdated > CONVERT(DATETIME, '2012-01-0100:00:00', 102))

I think that the main difference beside bit width is that decimal has exponent base 10 and double has 2

I know this is late, but I actually really like using:

import time
start = time.time()

##### your timed code here ... #####

print "Process time: " + (time.time() - start)

time.time() gives you seconds since the epoch. Because this is a standardized time in seconds, you can simply subtract the start time from the end time to get the process time (in seconds). time.clock() is good for benchmarking, but I have found it kind of useless if you want to know how long your process took. For example, it's much more intuitive to say "my process takes 10 seconds" than it is to say "my process takes 10 processor clock units"

>>> start = time.time(); sum([each**8.3 for each in range(1,100000)]) ; print (time.time() - start)
3.4001404476250935e+45
0.0637760162354
>>> start = time.clock(); sum([each**8.3 for each in range(1,100000)]) ; print (time.clock() - start)
3.4001404476250935e+45
0.05

In the first example above, you are shown a time of 0.05 for time.clock() vs 0.06377 for time.time()

>>> start = time.clock(); time.sleep(1) ; print "process time: " + (time.clock() - start)
process time: 0.0
>>> start = time.time(); time.sleep(1) ; print "process time: " + (time.time() - start)
process time: 1.00111794472

In the second example, somehow the processor time shows "0" even though the process slept for a second. time.time() correctly shows a little more than 1 second.

This will not help for the browser, but you can also define a proxy in your code to use with a HTTP client:

// proxy
private static final String PROXY = "123.123.123.123";
// proxy host
private static final HttpHost PROXY_HOST = new HttpHost(PROXY, 8080);
HttpParams httpParameters = new BasicHttpParams();
DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
httpClient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, PROXY_HOST);

Heap memory

The heap memory is the runtime data area from which the Java VM allocates memory for all class instances and arrays. The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects.

• Eden Space: The pool from which memory is initially allocated for most objects.

• Survivor Space: The pool containing objects that have survived the garbage collection of the Eden space.

• Tenured Generation or Old Gen: The pool containing objects that have existed for some time in the survivor space.

Non-heap memory

Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the Java VM. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors. The method area is logically part of the heap but, depending on the implementation, a Java VM may not garbage collect or compact it. Like the heap memory, the method area may be of a fixed or variable size. The memory for the method area does not need to be contiguous.

• Permanent Generation: The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.

• Code Cache: The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

In my case php-fpm outputs 500 error without any logging because of missing php-mysql module. I moved joomla installation to another server and forgot about it. So apt-get install php-mysql and service restart solved it.

I started with trying to fix broken logging without success. Finally with strace i found fail message after db-related system calls. Though my case is not directly related to op's question, I hope it could be useful.

You need to click Log Navigator icon (far right in left sidebar). Then choose your Debug/Run session in left sidebar, and you will have console in editor area.

When objects are constructed, it is always first construct base class subobject, therefore, base class constructor is called first, then call derived class constructors. The reason is that derived class objects contain subobjects inherited from base class. You always need to call the base class constructor to initialze base class subobjects. We usually call the base class constructor on derived class's member initialization list. If you do not call base class constructor explicitly, the compile will call the default constructor of base class to initialize base class subobject. However, implicit call on default constructor does not necessary work at all times (for example, if base class defines a constructor that could not be called without arguments).

When objects are out of scope, it will first call destructor of derived class,then call destructor of base class.

Some of the sites are speaking SSLv2, or at least sending an SSLv2 server-hello, and your client doesn't speak, or isn't configured to speak, SSLv2. You need to make a policy decision here. SSLv2 should have vanished from the face of the earth years ago, and sites that still use it are insecure. However, if you gotta talk to them, you just have to enable it at your end, if you can. I would complain to the site owners though if you can.

Ubuntu these days comes with ufw - Uncomplicated Firewall. ufw is an easy-to-use method of handling iptables rules.

Try using this command to allow a port

sudo ufw allow 1701

To test connectivity, you could try shutting down the VPN software (freeing up the ports) and using netcat to listen, like this:

nc -l 1701

Then use telnet from your Windows host and see what shows up on your Ubuntu terminal. This can be repeated for each port you'd like to test.

Open the svg using Inkscape.

Inkscape is a svg editor it is a bit like Illustrator but as it is built specifically for svg it handles it way better. It is a free software and it's available @ https://inkscape.org/en/

• ctrl A (select all)
• shift ctrl C (=Path/Object to paths)
• ctrl s (save (choose as plain svg))

done

all rect/circle have been converted to path

System.Environment has WorkingSet- a 64-bit signed integer containing the number of bytes of physical memory mapped to the process context.

If you want a lot of details there is System.Diagnostics.PerformanceCounter, but it will be a bit more effort to setup.

If you want to split the string, it's best to use:

$array = str_split($string);

When you have delimiter, which separates the string, you can try,

explode('' ,$string);

Where you can pass the delimiter in the first variable inside the explode such as:

explode(',',$string);

Been beating my head on this for the last couple of days on a repackaged base box. (Mac OS X, El Capitan)

Following @Radek 's procedure I did 'vagrant ssh-config' on the source box and got:

...
/Users/Shared/dev/<source-box-name>/.vagrant/machines/default/virtualbox/private_key
...

On the new copy, that command gave me:

...
IdentityFile /Users/<username>/.vagrant.d/insecure_private_key
...

So, I just added this line in the new copy:

...
config.ssh.private_key_path = "/Users/Shared/dev/<source-box-name>/.vagrant/machines/default/virtualbox/private_key"
...

Not perfect, but I can get on with my life.

I'm using Excel 2003 -

The problem with using conditional formatting here is that you can't reference another worksheet or workbook in your conditions. What you can to do is set some column on sheet 1 equal to the appropriate column on sheet 2 (in your example =Sheet2!B6). I used Column F in my example below. Then you can use conditional formatting. Select the cell at Sheet 1, row , column 1 and then go to the conditional formatting menu. Choose "Formula Is" from the drop down and set the condition to "=$F$6=4". Click on the format button and then choose the Patterns tab. Choose the color you want and you're done.

You can use the format painter tool to apply conditional formatting to other cells, but be aware that by default Excel uses absolute references in the conditions. If you want them to be relative you'll need to remove the dollar signs from the condition.

You can have up to 3 conditions applied to a cell (use the add >> button at the bottom of the Conditional formatting dialog) so if the last row is fixed (for example, you know that it will always be row 10) you can use it as a condition to set the background color to none. Assuming that the last value you care about is in row 10 then (still assuming that you've set column F on sheet1 to the corresponding cells on sheet 2) then set the 1st condition to Formula Is =$F$10="" and the pattern to None. Make it the first condition and it will override any following conflicting statements.

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

If we follow the w3 org table reference ,and follow the Permitted Contents section, we can see that the table tags takes tbody(optional) and tr as the only permitted contents.

So i reckon it is safe to say we cannot add a div tag which is a flow content as a direct child of the table which i understand is what you meant when you had said above a tr.

Having said that , as we follow the above link , you will find that it is safe to use divs inside the td element as seen here

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

If you insist on deleting it:

git remote remove origin

Or if you have Git version 1.7.10 or older

git remote rm origin

But kahowell's answer is better.

replace code in onClick() method with this:

Intent myIntent = new Intent(this, Katra_home.class);
startActivity(myIntent);

No refresh is needed if the "val"-parameter is used for setting the value, see fiddle. Use brackets for the value to enable multiple selected values.

$('.selectpicker').selectpicker('val', [1]); 

For having .html files parsed as well, you need to set the appropriate handler in your server config.

For Apache httpd 2.X this is the following line

AddHandler application/x-httpd-php .html

See the PHP docu for information on your specific server installation.

for in loops over enumerable property names of an object.

for of (new in ES6) does use an object-specific iterator and loops over the values generated by that.

In your example, the array iterator does yield all the values in the array (ignoring non-index properties).

Use the .data() method:

$('div').data('info', '222');

Note that this doesn't create an actual data-info attribute. If you need to create the attribute, use .attr():

$('div').attr('data-info', '222');

Each image has a resource-number, which is an integer. Pass this number to "setImageResource" and you should be ok.

Check this link for further information:
http://developer.android.com/guide/topics/resources/accessing-resources.html

e.g.:

imageView.setImageResource(R.drawable.myimage);

In general, I always put my enums in a struct. I have seen several guidelines including "prefixing".

enum Color
{
  Clr_Red,
  Clr_Yellow,
  Clr_Blue,
};

Always thought this looked more like C guidelines than C++ ones (for one because of the abbreviation and also because of the namespaces in C++).

So to limit the scope we now have two alternatives:

• namespaces
• structs/classes

I personally tend to use a struct because it can be used as parameters for template programming while a namespace cannot be manipulated.

Examples of manipulation include:

template <class T>
size_t number() { /**/ }

which returns the number of elements of enum inside the struct T :)

Make sure the last line of your .bash_profile is:

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

There are many solutions to retrieve URI query values, I prefer this one because it's short and works great:

function get(name){
   if(name=(new RegExp('[?&]'+encodeURIComponent(name)+'=([^&]*)')).exec(location.search))
      return decodeURIComponent(name[1]);
}

To create the regex from a string, you have to use JavaScript's RegExp object.

If you also want to match/replace more than one time, then you must add the g (global match) flag. Here's an example:

var stringToGoIntoTheRegex = "abc";
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

In the general case, escape the string before using as regex:

Not every string is a valid regex, though: there are some speciall characters, like ( or [. To work around this issue, simply escape the string before turning it into a regex. A utility function for that goes in the sample below:

function escapeRegExp(stringToGoIntoTheRegex) {
    return stringToGoIntoTheRegex.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
}

var stringToGoIntoTheRegex = escapeRegExp("abc"); // this is the only change from above
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

Note: the regex in the question uses the s modifier, which didn't exist at the time of the question, but does exist -- a s (dotall) flag/modifier in JavaScript -- today.

use ISNULL embedded function.

    public string HtmlAgi(string url, string key)
    {

        var Webget = new HtmlWeb();
        var doc = Webget.Load(url);
        HtmlNode ourNode = doc.DocumentNode.SelectSingleNode(string.Format("//meta[@name='{0}']", key));

        if (ourNode != null)
        {


                return ourNode.GetAttributeValue("content", "");

        }
        else
        {
            return "not fount";
        }

    }

I have this function for this case ..

Function GetValue(r As Range, Tag As String) As Integer
Dim c, nRet As String
Dim n, x As Integer
Dim bNum As Boolean

c = r.Value
n = InStr(c, Tag)
For x = n + 1 To Len(c)
  Select Case Mid(c, x, 1)
    Case ":":    bNum = True
    Case " ": Exit For
    Case Else: If bNum Then nRet = nRet & Mid(c, x, 1)
  End Select
Next
GetValue = val(nRet)
End Function

To fill cell BC .. (assumed that you check cell A1)

Worksheets("Übersicht_2013").Cells(i, "BC") = GetValue(range("A1"),"S")

For people like me, linq addicts, and based on svick's answer, here a linq approach:

using System.Linq;
//...
//make it linq iterable. 
var obj_linq = Response.Cast<KeyValuePair<string, JToken>>();

Now you can make linq expressions like:

JToken x = obj_linq
          .Where( d => d.Key == "my_key")
          .Select(v => v)
          .FirstOrDefault()
          .Value;
string y = ((JValue)x).Value;

Or just:

var y = obj_linq
       .Where(d => d.Key == "my_key")
       .Select(v => ((JValue)v.Value).Value)
       .FirstOrDefault();

Or this one to iterate over all data:

obj_linq.ToList().ForEach( x => { do stuff } ); 

Kubernetes and Mesos are a match made in heaven. Kubernetes enables the Pod (group of co-located containers) abstraction, along with Pod labels for service discovery, load-balancing, and replication control. Mesos provides the fine-grained resource allocations for pods across nodes in a cluster, and can make Kubernetes play nicely with other frameworks running on the same cluster resources.

from readme of kubernetes-mesos

new Date().toISOString().slice(0,10); 

would work too

For beginners, I wanted to add to the accepted answer, because a couple of subtleties were unclear to me:

To find and modify text (not completely replace),

1. In the "Find" step, you can use regex with "capturing groups," e.g. your search could be la la la (group1) blah blah (group2), using parentheses.

2. And then in the "Replace" step, you can refer to the capturing groups via $1, $2 etc.

So, for example, in this case we could find the relevant text with just <h1>.+?<\/h1> (no parentheses), but putting in the parentheses <h1>(.+?)<\/h1> allows us to refer to the sub-match in between them as $1 in the replace step. Cool!

Notes

• To turn on Regex in the Find Widget, click the .* icon, or press Cmd/Ctrl Alt R

• $0 refers to the whole match

• Finally, the original question states that the replace should happen "within a document," so you can use the "Find Widget" (Cmd or Ctrl + F), which is local to the open document, instead of "Search", which opens a bigger UI and looks across all files in the project.

Set a session variable for every page on your site (actual pages not includes or rpcs) that contains the current page name, then in your Ajax call pass a nonce salted with the $_SERVER['SCRIPT_NAME'];

<?php
function create_nonce($optional_salt='')
{
    return hash_hmac('sha256', session_id().$optional_salt, date("YmdG").'someSalt'.$_SERVER['REMOTE_ADDR']);
}
$_SESSION['current_page'] = $_SERVER['SCRIPT_NAME'];
?>

<form>
  <input name="formNonce" id="formNonce" type="hidden" value="<?=create_nonce($_SERVER['SCRIPT_NAME']);?>">
  <label class="form-group">
    Login<br />
    <input name="userName" id="userName" type="text" />
  </label>
  <label class="form-group">
    Password<br />
    <input name="userPassword" id="userPassword" type="password" />
  </label>
  <button type="button" class="btnLogin">Sign in</button>
</form>
<script type="text/javascript">
    $("form.login button").on("click", function() {
        authorize($("#userName").val(),$("#userPassword").val(),$("#formNonce").val());
    });

    function authorize (authUser, authPassword, authNonce) {
        $.ajax({
          type: "POST",
          url: "/inc/rpc.php",
          dataType: "json",
          data: "userID="+authUser+"&password="+authPassword+"&nonce="+authNonce
        })
        .success(function( msg ) {
            //some successful stuff
        });
    }
</script>

Then in the rpc you are calling test the nonce you passed, if it is good then odds are pretty great that your rpc was legitimately called:

<?php
function check_nonce($nonce, $optional_salt='')
{
    $lasthour = date("G")-1<0 ? date('Ymd').'23' : date("YmdG")-1;
    if (hash_hmac('sha256', session_id().$optional_salt, date("YmdG").'someSalt'.$_SERVER['REMOTE_ADDR']) == $nonce || 
        hash_hmac('sha256', session_id().$optional_salt, $lasthour.'someSalt'.$_SERVER['REMOTE_ADDR']) == $nonce)
    {
        return true;
    } else {
        return false;
    }
}

$ret = array();
header('Content-Type: application/json');
if (check_nonce($_POST['nonce'], $_SESSION['current_page']))
{
    $ret['nonce_check'] = 'passed';
} else {
    $ret['nonce_check'] = 'failed';
}
echo json_encode($ret);
exit;
?>

edit: FYI the way I have it set the nonce is only good for an hour and change, so if they have not refreshed the page doing the ajax call in the last hour or 2 the ajax request will fail.

I think the best answer that I've seen has been @MD_Sayem_Ahmed.

Your question is "How can I parse Json with C#", but it seems like you are wanting to decode Json. If you are wanting to decode it, Ahmed's answer is good.

If you are trying to accomplish this in ASP.NET Web Api, the easiest way is to create a data transfer object that holds the data you want to assign:

public class MyDto{
    public string Name{get; set;}
    public string Value{get; set;}
}

You have simply add the application/json header to your request (if you are using Fiddler, for example). You would then use this in ASP.NET Web API as follows:

//controller method -- assuming you want to post and return data
public MyDto Post([FromBody] MyDto myDto){
   MyDto someDto = myDto;
   /*ASP.NET automatically converts the data for you into this object 
    if you post a json object as follows:
{
    "Name": "SomeName",
      "Value": "SomeValue"
}
*/
   //do some stuff
}

This helped me a lot when I was working in my Web Api and made my life super easy.

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

PHP runs on the server before the page is sent to the user, JavaScript is run on the user's computer once it is received, so the PHP script has already executed.

If you want to pass a JavaScript value to a PHP script, you'd have to do an XMLHttpRequest to send the data back to the server.

Here's a previous question that you can follow for more information: Ajax Tutorial

Now if you just need to pass a form value to the server, you can also just do a normal form post, that does the same thing, but the whole page has to be refreshed.

<?php
if(isset($_POST))
{
  print_r($_POST);
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
  <input type="text" name="data" value="1" />
  <input type="submit" value="Submit" />
</form>

Clicking submit will submit the page, and print out the submitted data.

I was having this same issue and I had to work it out. I tried these solutions, but at the end the performance, at least for the scrolling didn't improve at all. So here the workaroud that I did perform and the explanation of why it did work for me.

If you had the chance to explore the drag events, just a little, by creating a "MiWebView" Class, overwriting the "onTouchEvent" method and at least printed the time in which every drag event occurs, you'll see that they are separated in time for (down to) 9ms away. That is a very short time in between events.

Take a look at the WebView Source Code, and just see the onTouchEvent function. It is just impossible for it to be handled by the processor in less than 9ms (Keep on dreaming!!!). That's why you constantly see the "Miss a drag as we are waiting for WebCore's response for touch down." message. The code just can't be handled on time.

How to fix it? First, you can not re-write the onTouchEvent code to improve it, it is just too much. But, you can "mock it" in order to limit the event rate for dragging movements let's say to 40ms or 50ms. (this depends on the processor).

All touch events go like this: ACTION_DOWN -> ACTION_MOVE......ACTION_MOVE -> ACTION_UP. So we need to keep the DOWN and UP movements and filter the MOVE rate (these are the bad guys).

And here is a way to do it (you can add more event types like 2 fingers touch, all I'm interested here is the single finger scrolling).

import android.content.Context;
import android.view.MotionEvent;
import android.webkit.WebView;


public class MyWebView extends WebView{

    public MyWebView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    private long lastMoveEventTime = -1;
    private int eventTimeInterval = 40;

    @Override
    public boolean onTouchEvent(MotionEvent ev) {

        long eventTime = ev.getEventTime();
        int action = ev.getAction();

        switch (action){
            case MotionEvent.ACTION_MOVE: {
                if ((eventTime - lastMoveEventTime) > eventTimeInterval){
                    lastMoveEventTime = eventTime;
                    return super.onTouchEvent(ev);
                }
                break;
            }
            case MotionEvent.ACTION_DOWN:
            case MotionEvent.ACTION_UP: {
                return super.onTouchEvent(ev);
            }
        }
        return true;
    }
}

Of course Use this class instead of WebView and you'll see the difference when scrolling.

This is just an approach to a solution, yet still not fully implemented for all lag cases due to screen touching when using WebView. However it is the best solution I found, at least for my specific needs.

Do below steps :

1. Check the version of chrome browser.

2. download chromedriver of same version from https://sites.google.com/a/chromium.org/chromedriver/

3. Give correct path in the pycharm and run the code.
