I found this way of using ajax which helped me as it was better in use as not having complex json syntaxes

//fifth
function GetAjaxDataPromise(url, postData) {
    debugger;
    var promise = $.post(url, postData, function (promise, status) {
    });
    return promise;
};
$(function () {
    $("#btnGet5").click(function () {
        debugger;
        var promises = GetAjaxDataPromise('@Url.Action("AjaxMethod", "Home")', { EmpId: $("#txtId").val(), EmpName: $("#txtName").val(), EmpSalary: $("#txtSalary").val() });
        promises.done(function (response) {
            debugger;
            alert("Hello: " + response.EmpName + " Your Employee Id Is: " + response.EmpId + "And Your Salary Is: " + response.EmpSalary);
        });
    });
});

This method comes with jquery promise the best part was on controller we can received data by using separate parameters or just by using a model class.

[HttpPost]
    public JsonResult AjaxMethod(PersonModel personModel)
    {
        PersonModel person = new PersonModel
        {
            EmpId = personModel.EmpId,
            EmpName = personModel.EmpName,
            EmpSalary = personModel.EmpSalary
        };
        return Json(person);
    }

or

[HttpPost]
    public JsonResult AjaxMethod(string empId, string empName, string empSalary)
    {
        PersonModel person = new PersonModel
        {
            EmpId = empId,
            EmpName = empName,
            EmpSalary = empSalary
        };
        return Json(person);
    } 

It works for both of the cases. SO you must try out this way. Got the reference from Using Ajax With Asp.Net MVC

There are few more ways of using Ajax explained there other than this one which you must try.

1) When the user logs out (Forms signout in Action) I want to redirect to a login page.

public ActionResult Logout() {
    //log out the user
    return RedirectToAction("Login");
}

2) In a Controller or base Controller event eg Initialze, I want to redirect to another page (AbsoluteRootUrl + Controller + Action)

Why would you want to redirect from a controller init?

the routing engine automatically handles requests that come in, if you mean you want to redirect from the index action on a controller simply do:

public ActionResult Index() {
    return RedirectToAction("whateverAction", "whateverController");
}

each passes into your function index and element. Check index against the length of the set and you're good to go:

var set = $('.requiredText');
var length = set.length;
set.each(function(index, element) {
      thisVal = $(this).val();
      if(parseInt(thisVal) !== 0) {
          console.log('Valid Field: ' + thisVal);
          if (index === (length - 1)) {
              console.log('Last field, submit form here');
          }
      }
});

By default maven does not include any files from "src/main/java".

You have two possible way to that.

1. put all your resource files (different than java files) to "src/main/resources" - this is highly recommended

2. Add to your pom (resource plugin):

?

 <resources>
       <resource>
           <directory>src/main/resources</directory>
        </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
  </resources>

You suggested below to iterate

Dictionary<string,object> myDictionary = new Dictionary<string,object>();
//Populate your dictionary here

foreach (KeyValuePair<string,object> kvp in myDictionary) {
    //Do some interesting things;
}

FYI, foreach doesn't work if the value are of type object.

Use an iframe for the nested form. If they need to share fields, then... it's not really nested.

I found that:

git log --reverse

shows commits from start.

Using print and JSON.stringify you can simply produce a valid JSON result.
Use --quiet flag to filter shell noise from the output.
Use --norc flag to avoid .mongorc.js evaluation. (I had to do it because of a pretty-formatter that I use, which produces invalid JSON output) Use DBQuery.shellBatchSize = ? replacing ? with the limit of the actual result to avoid paging.

And finally, use tee to pipe the terminal output to a file:

// Shell:
mongo --quiet --norc ./query.js | tee ~/my_output.json

// query.js:
DBQuery.shellBatchSize = 2000;
function toPrint(data) {
  print(JSON.stringify(data, null, 2));
}

toPrint(
  db.getCollection('myCollection').find().toArray()
);

Hope this helps!

There have been methodologies in all languages advocating for use of a single return statement in any function. However impossible it may be in certain code, some people do strive for that, however, it may end up making your code more complex (as in more lines of code), but on the other hand, somewhat easier to follow (as in logic flow).

This will not mess up garbage collection in any way!!

The better way to do it is to set a boolean value, if you want to listen to him.

boolean flag = false;
for(int i=0; i<array.length; ++i){
    if(array[i] == valueToFind) {
        flag = true;
        break;
    }
}
return flag;

short version if you have Router imported then you can simply use some thing like

this.router.url === "/search"

else do the following

1) Import the router

import { Router } from '@angular/router';

2) Declare its entry in constructor

constructor(private router: Router) { }

3) Use its value in your function

yourFunction(){
    if(this.router.url === "/search"){
        //some logic
    }
}

@victor answer helped me, this is the same answer as him but with a little detail, as it might help someone

Check you have the correct startup project selected. I had a web api project as startup. That generated this error.

try to add ojdbc6.jar or other version through the server lib "C:\apache-tomcat-7.0.47\lib",

Then restart the server in eclipse.

If the pop-up's document is from a different domain, this is simply not possible.

Update April 2015: I was wrong about this: if you own both domains, you can use window.postMessage and the message event in pretty much all browsers that are relevant today.

If not, there's still no way you'll be able to make this work cross-browser without some help from the document being loaded into the pop-up. You need to be able to detect a change in the pop-up that occurs once it has loaded, which could be a variable that JavaScript in the pop-up page sets when it handles its own load event, or if you have some control of it you could add a call to a function in the opener.

<div id="video_box">
  <div id="video_overlays"></div>
  <div>
    <video id="player" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" type="video/webm" onclick="this.play();">Your browser does not support this streaming content.</video>
  </div>
</div>

for this you need to just add css like this:

#video_overlays {
  position: absolute;
  background-color: rgba(0, 0, 0, 0.46);
  z-index: 2;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}
#video_box{position: relative;}

Use nbio non-blocking i/o library or whatever, if you need more threads for doing I/O calls that block

The reason is that php://input returns all the raw data after the HTTP-headers of the request, regardless of the content type.

The PHP superglobal $_POST, only is supposed to wrap data that is either

• application/x-www-form-urlencoded (standard content type for simple form-posts) or
• multipart/form-data (mostly used for file uploads)

This is because these are the only content types that must be supported by user agents. So the server and PHP traditionally don't expect to receive any other content type (which doesn't mean they couldn't).

So, if you simply POST a good old HTML form, the request looks something like this:

POST /page.php HTTP/1.1

key1=value1&key2=value2&key3=value3

But if you are working with Ajax a lot, this probaby also includes exchanging more complex data with types (string, int, bool) and structures (arrays, objects), so in most cases JSON is the best choice. But a request with a JSON-payload would look something like this:

POST /page.php HTTP/1.1

{"key1":"value1","key2":"value2","key3":"value3"}

The content would now be application/json (or at least none of the above mentioned), so PHP's $_POST-wrapper doesn't know how to handle that (yet).

The data is still there, you just can't access it through the wrapper. So you need to fetch it yourself in raw format with file_get_contents('php://input') (as long as it's not multipart/form-data-encoded).

This is also how you would access XML-data or any other non-standard content type.

I prefer to not rely on shell aliases or another package.

Adding a simple line to scripts section of your package.json, you can run local npm commands like

npm run webpack

package.json

{
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "webpack": "webpack"
  },
  "devDependencies": {
    "webpack": "^4.1.1",
    "webpack-cli": "^2.0.11"
  }
}

I. In your build.gradle add latest appcompat library, at the time 24.2.1

dependencies {  
    compile 'com.android.support:appcompat-v7:X.X.X' 
    // where X.X.X version
}

II. Make your activity extend android.support.v7.app.AppCompatActivity and implement the DatePickerDialog.OnDateSetListener interface.

public class MainActivity extends AppCompatActivity  
    implements DatePickerDialog.OnDateSetListener {

III. Create your DatePickerDialog setting a context, the implementation of the listener and the start year, month and day of the date picker.

DatePickerDialog datePickerDialog = new DatePickerDialog(  
    context, MainActivity.this, startYear, starthMonth, startDay);

IV. Show your dialog on the click event listener of your button

((Button) findViewById(R.id.myButton))
    .setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        datePickerDialog.show();
    }
});

TMTOWTDI, chose the method that best fits how you work. I use the environment method so I don't have to think about it.

In the environment:

export PERL_UNICODE=SDL

on the command line:

perl -CSDL -le 'print "\x{1815}"';

or with binmode:

binmode(STDOUT, ":utf8");          #treat as if it is UTF-8
binmode(STDIN, ":encoding(utf8)"); #actually check if it is UTF-8

or with PerlIO:

open my $fh, ">:utf8", $filename
    or die "could not open $filename: $!\n";

open my $fh, "<:encoding(utf-8)", $filename
    or die "could not open $filename: $!\n";

or with the open pragma:

use open ":encoding(utf8)";
use open IN => ":encoding(utf8)", OUT => ":utf8";

Well, your syntax isn't really Python to begin with.

Iterations in Python are over he contents of containers (well, technically it's over iterators), with a syntax for item in container. In this case, the container is the cars list, but you want to skip the first and last elements, so that means cars[1:-1] (python lists are zero-based, negative numbers count from the end, and : is slicing syntax.

So you want

for c in cars[1:-1]:
    do something with c

use #0000 (only four zeros otherwise it will be considered as black) this is the color code for transparent. You can use it directly but I recommend you to define a color in color.xml so you can enjoy re-usefullness of the code.

OpenGL should be present already - it will probably be Freeglut / GLUT that is missing.

GLUT is very dated now and not actively supported - so you should certainly be using Freeglut instead. You won't have to change your code at all, and a few additional features become available.

You'll find pre-packaged sets of files from here: http://freeglut.sourceforge.net/index.php#download If you don't see the "lib" folder, it's because you didn't download the pre-packaged set. "Martin Payne's Windows binaries" is posted at above link and works on Windows 8.1 with Visual Studio 2013 at the time of this writing.

When you download these you'll find that the Freeglut folder has three subfolders: - bin folder: this contains the dll files for runtime - include: the header files for compilation - lib: contains library files for compilation/linking

Installation instructions usually suggest moving these files into the visual studio folder and the Windows system folder: It is best to avoid doing this as it makes your project less portable, and makes it much more difficult if you ever need to change which version of the library you are using (old projects might suddenly stop working, etc.)

Instead (apologies for any inconsistencies, I'm basing these instructions on VS2010)... - put the freeglut folder somewhere else, e.g. C:\dev - Open your project in Visual Studio - Open project properties - There should be a tab for VC++ Directories, here you should add the appropriate include and lib folders, e.g.: C:\dev\freeglut\include and C:\dev\freeglut\lib - (Almost) Final step is to ensure that the opengl lib file is actually linked during compilation. Still in project properties, expand the linker menu, and open the input tab. For Additional Dependencies add opengl32.lib (you would assume that this would be linked automatically just by adding the include GL/gl.h to your project, but for some reason this doesn't seem to be the case)

At this stage your project should compile OK. To actually run it, you also need to copy the freeglut.dll files into your project folder

You can easily enable debugging support using an option for the @EnableWebSecurity annotation:

@EnableWebSecurity(debug = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    …
}

Here is a concise summary of what most answers are talking about.

Let's say we have two variables and $1 is set to 'one':

set one two
a=hello
b=world

The table below explains the different contexts where we can combine the values of a and b to create a new variable, c.

Context                               | Expression            | Result (value of c)
--------------------------------------+-----------------------+---------------------
Two variables                         | c=$a$b                | helloworld
A variable and a literal              | c=${a}_world          | hello_world
A variable and a literal              | c=$1world             | oneworld
A variable and a literal              | c=$a/world            | hello/world
A variable, a literal, with a space   | c=${a}" world"        | hello world
A more complex expression             | c="${a}_one|${b}_2"   | hello_one|world_2
Using += operator (Bash 3.1 or later) | c=$a; c+=$b           | helloworld
Append literal with +=                | c=$a; c+=" world"     | hello world

A few notes:

• enclosing the RHS of an assignment in double quotes is generally a good practice, though it is quite optional in many cases
• += is better from a performance standpoint if a big string is being constructed in small increments, especially in a loop
• use {} around variable names to disambiguate their expansion (as in row 2 in the table above). As seen on rows 3 and 4, there is no need for {} unless a variable is being concatenated with a string that starts with a character that is a valid first character in shell variable name, that is alphabet or underscore.

• BashFAQ/013 - How can I concatenate two variables?
• When do we need curly braces around shell variables?

Here is an independent and efficient method to count UTF-8 bytes of a string.

//count UTF-8 bytes of a string_x000D_
function byteLengthOf(s){_x000D_
 //assuming the String is UCS-2(aka UTF-16) encoded_x000D_
 var n=0;_x000D_
 for(var i=0,l=s.length; i<l; i++){_x000D_
  var hi=s.charCodeAt(i);_x000D_
  if(hi<0x0080){ //[0x0000, 0x007F]_x000D_
   n+=1;_x000D_
  }else if(hi<0x0800){ //[0x0080, 0x07FF]_x000D_
   n+=2;_x000D_
  }else if(hi<0xD800){ //[0x0800, 0xD7FF]_x000D_
   n+=3;_x000D_
  }else if(hi<0xDC00){ //[0xD800, 0xDBFF]_x000D_
   var lo=s.charCodeAt(++i);_x000D_
   if(i<l&&lo>=0xDC00&&lo<=0xDFFF){ //followed by [0xDC00, 0xDFFF]_x000D_
    n+=4;_x000D_
   }else{_x000D_
    throw new Error("UCS-2 String malformed");_x000D_
   }_x000D_
  }else if(hi<0xE000){ //[0xDC00, 0xDFFF]_x000D_
   throw new Error("UCS-2 String malformed");_x000D_
  }else{ //[0xE000, 0xFFFF]_x000D_
   n+=3;_x000D_
  }_x000D_
 }_x000D_
 return n;_x000D_
}_x000D_
_x000D_
var s="\u0000\u007F\u07FF\uD7FF\uDBFF\uDFFF\uFFFF";_x000D_
console.log("expect byteLengthOf(s) to be 14, actually it is %s.",byteLengthOf(s));

Note that the method may throw error if an input string is UCS-2 malformed

The issue here is that you've initialized your array, but not its elements; they are all null. So if you try to reference houses[0], it will be null.

Here's a great little helper method you could write for yourself:

T[] InitializeArray<T>(int length) where T : new()
{
    T[] array = new T[length];
    for (int i = 0; i < length; ++i)
    {
        array[i] = new T();
    }

    return array;
}

Then you could initialize your houses array as:

GameObject[] houses = InitializeArray<GameObject>(200);

In Java 8 atomic classes have been extended with two interesting functions:

• int getAndUpdate(IntUnaryOperator updateFunction)
• int updateAndGet(IntUnaryOperator updateFunction)

Both are using the updateFunction to perform update of the atomic value. The difference is that the first one returns old value and the second one return the new value. The updateFunction may be implemented to do more complex "compare and set" operations than the standard one. For example it can check that atomic counter doesn't go below zero, normally it would require synchronization, and here the code is lock-free:

    public class Counter {

      private final AtomicInteger number;

      public Counter(int number) {
        this.number = new AtomicInteger(number);
      }

      /** @return true if still can decrease */
      public boolean dec() {
        // updateAndGet(fn) executed atomically:
        return number.updateAndGet(n -> (n > 0) ? n - 1 : n) > 0;
      }
    }

The code is taken from Java Atomic Example.

You would need to attach your click event to some element. If there are lots of other elements on the page you would not want to attach a click event to all of them.

One potential way would be to create a transparent div below your dropdown menu but above all other elements on the page. You would show it when the drop down was shown. Have the element have a click hander that hides the drop down and the transparent div.

$('#clickCatcher').click(function () { _x000D_
  $('#dropContainer').hide();_x000D_
  $(this).hide();_x000D_
});

#dropContainer { z-index: 101; ... }_x000D_
#clickCatcher { position: absolute; top: 0; left: 0; width: 100%; height: 100%; z-index: 100; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="dropDown"></div>_x000D_
<div id="clickCatcher"></div>

Though this seems to be an old question with many answers I'm posting another one, because it provides information about another approaches (looking more convenient than already mentioned), and the question itself remains actual.

First, there is a blogpost Running multiple versions of Google Chrome on Windows. It describes a method which works, but has 2 drawbacks:

• you can't run Chrome instances of different versions simultaneously;
• from time to time, Chrome changes format of its profile, and as long as 2 versions installed by this method share the same directory with profiles, this may produce a problem if it's happened to test 2 versions with incompatible profile formats;

Second method is a preferred one, which I'm currently using. It relies on portable versions of Chrome, which become available for every stable release at the portableapps.com.

The only requirement of this method is that existing Chrome version should not run during installation of a next version. Of course, each version must be installed in a separate directory. This way, after installation, you can run Chromes of different versions in parallel. Of course, there is a drawback in this method as well:

• profiles in all versions live separately, so if you need to setup a profile in a specific way, you should do it twice or more times, according to the number of different Chrome versions you have installed.

You can use:

NSString *newString;
if ( [[myString characterAtIndex:0] isEqualToString:@"*"] ) {
     newString = [myString substringFromIndex:1];
}

If you are using bash you can try alias:

into the .bashrc file add this line:

alias p='cd /home/serdar/my_new_folder/path/'

when you write "p" on the command line, it will change the directory.

import datetime
import numpy as np
from matplotlib.backends.backend_pdf import PdfPages
import matplotlib.pyplot as plt

# Create the PdfPages object to which we will save the pages:
# The with statement makes sure that the PdfPages object is closed properly at
# the end of the block, even if an Exception occurs.
with PdfPages('multipage_pdf.pdf') as pdf:
    plt.figure(figsize=(3, 3))
    plt.plot(range(7), [3, 1, 4, 1, 5, 9, 2], 'r-o')
    plt.title('Page One')
    pdf.savefig()  # saves the current figure into a pdf page
    plt.close()

    plt.rc('text', usetex=True)
    plt.figure(figsize=(8, 6))
    x = np.arange(0, 5, 0.1)
    plt.plot(x, np.sin(x), 'b-')
    plt.title('Page Two')
    pdf.savefig()
    plt.close()

    d['ModDate'] = datetime.datetime.today()

Best could be ng new myApp --style=scss

Then Angular CLI will create any new component with scss for you...

Note that using scss not working in the browser as you probably know.. so we need something to compile it to css, for this reason we can use node-sass, install it like below:

npm install node-sass --save-dev

and you should be good to go!

If you using webpack, read on here:

Command line inside project folder where your existing package.json is: npm install node-sass sass-loader raw-loader --save-dev

In webpack.common.js, search for "rules:" and add this object to the end of the rules array (don't forget to add a comma to the end of the previous object):

{
  test: /\.scss$/,
  exclude: /node_modules/,
  loaders: ['raw-loader', 'sass-loader'] // sass-loader not scss-loader
}

Then in your component:

@Component({
  styleUrls: ['./filename.scss'],
})

If you want global CSS support then on the top level component (likely app.component.ts) remove encapsulation and include the SCSS:

import {ViewEncapsulation} from '@angular/core';

@Component({
  selector: 'app',
  styleUrls: ['./bootstrap.scss'],
  encapsulation: ViewEncapsulation.None,
  template: ``
})
class App {}

from Angular starter here.

This is how I solved it based on this post with some minor tweaks. This solution does not require creation of any additional classes.

SSLContext sc = SSLContext.getInstance("SSLv3");

KeyManagerFactory kmf =
    KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );

KeyStore ks = KeyStore.getInstance( KeyStore.getDefaultType() );
ks.load(new FileInputStream( certPath ), certPasswd.toCharArray() );

kmf.init( ks, certPasswd.toCharArray() );

sc.init( kmf.getKeyManagers(), null, null );

((BindingProvider) webservicePort).getRequestContext()
    .put(
        "com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory",
        sc.getSocketFactory() );

Honestly basename and dirname solutions are easier, but you can also check this out :

find . -type f | grep -oP "[^/]*$"

or

find . -type f | rev | cut -d '/' -f1 | rev

or

find . -type f | sed "s/.*\///"

This should work:

var result = cmd.ExecuteScalar();
conn.Close();

return result != null ? result.ToString() : string.Empty;

Also, I'd suggest using Parameters in your query, something like (just a suggestion):

var cmd = new SqlCommand
{
    Connection = conn,
    CommandType = CommandType.Text,
    CommandText = "select COUNT(idemp_atd) absentDayNo from td_atd where absentdate_atd between @sdate and @edate and idemp_atd=@idemp group by idemp_atd"
};

cmd.Parameters.AddWithValue("@sdate", sdate);
cmd.Parameters.AddWithValue("@edate", edate);
// etc ...

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

Eclipse v4.7 (Oxygen).

Yes as long as it is public and you pass the correct args. See this link for more information. http://www.codestyle.org/java/faq-CommandLine.shtml#mainhost

Use the GeoCoding API

For example, to lookup zip 77379 use a request like this:

https://maps.googleapis.com/maps/api/geocode/json?address=77379&sensor=true&key=YOUR_GOOGLE_PLATFORM_API_KEY

If you don't mind using a third-party library, Eclipse Collections has zipWithIndex and forEachWithIndex available for use across many types. Here's a set of solutions to this challenge for both JDK types and Eclipse Collections types using zipWithIndex.

String[] names = { "Sam", "Pamela", "Dave", "Pascal", "Erik" };
ImmutableList<String> expected = Lists.immutable.with("Erik");
Predicate<Pair<String, Integer>> predicate =
    pair -> pair.getOne().length() <= pair.getTwo() + 1;

// JDK Types
List<String> strings1 = ArrayIterate.zipWithIndex(names)
    .collectIf(predicate, Pair::getOne);
Assert.assertEquals(expected, strings1);

List<String> list = Arrays.asList(names);
List<String> strings2 = ListAdapter.adapt(list)
    .zipWithIndex()
    .collectIf(predicate, Pair::getOne);
Assert.assertEquals(expected, strings2);

// Eclipse Collections types
MutableList<String> mutableNames = Lists.mutable.with(names);
MutableList<String> strings3 = mutableNames.zipWithIndex()
    .collectIf(predicate, Pair::getOne);
Assert.assertEquals(expected, strings3);

ImmutableList<String> immutableNames = Lists.immutable.with(names);
ImmutableList<String> strings4 = immutableNames.zipWithIndex()
    .collectIf(predicate, Pair::getOne);
Assert.assertEquals(expected, strings4);

MutableList<String> strings5 = mutableNames.asLazy()
    .zipWithIndex()
    .collectIf(predicate, Pair::getOne, Lists.mutable.empty());
Assert.assertEquals(expected, strings5);

Here's a solution using forEachWithIndex instead.

MutableList<String> mutableNames =
    Lists.mutable.with("Sam", "Pamela", "Dave", "Pascal", "Erik");
ImmutableList<String> expected = Lists.immutable.with("Erik");

List<String> actual = Lists.mutable.empty();
mutableNames.forEachWithIndex((name, index) -> {
        if (name.length() <= index + 1)
            actual.add(name);
    });
Assert.assertEquals(expected, actual);

If you change the lambdas to anonymous inner classes above, then all of these code examples will work in Java 5 - 7 as well.

Note: I am a committer for Eclipse Collections

From version 1.6.1 on, it's advisable to use the method prop for boolean attributes/properties such as selected, readonly, enabled,...

var theValue = "whatever";
$("#selectID").val( theValue ).prop('selected',true);

For more info, please refer to to http://blog.jquery.com/2011/05/12/jquery-1-6-1-released/

Since the count is the intended final value, in your query pass

$this->db->distinct();
$this->db->select('accessid');
$this->db->where('record', $record); 
$query = $this->db->get()->result_array();
return count($query);

The count the retuned value

Thanks Andy W

I found that the mid() did not quite work as I expected and I modified as follows:

def mid(s, offset, amount):
    return s[offset-1:offset+amount-1]

I performed the following test:

print('[1]23', mid('123', 1, 1))
print('1[2]3', mid('123', 2, 1))
print('12[3]', mid('123', 3, 1))
print('[12]3', mid('123', 1, 2))
print('1[23]', mid('123', 2, 2))

Which resulted in:

[1]23 1
1[2]3 2
12[3] 3
[12]3 12
1[23] 23

Which was what I was expecting. The original mid() code produces this:

[1]23 2
1[2]3 3
12[3] 
[12]3 23
1[23] 3

But the left() and right() functions work fine. Thank you.

To use the default system proxies (e.g. from the http_support environment variable), the following works for the current request (without installing it into urllib2 globally):

url = 'http://www.example.com/'
proxy = urllib2.ProxyHandler()
opener = urllib2.build_opener(proxy)
in_ = opener.open(url)
in_.read()

Most popular answers here with BaseController didn't worked for me on Laravel 5.4, but they have worked on 5.3. No idea why.

I have found a way which works on Laravel 5.4 and gives variables even for views which are skipping controllers. And, of course, you can get variables from the database.

add in your app/Providers/AppServiceProvider.php

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        // Using view composer to set following variables globally
        view()->composer('*',function($view) {
            $view->with('user', Auth::user());
            $view->with('social', Social::all()); 
            // if you need to access in controller and views:
            Config::set('something', $something); 
        });
    }
}

Try the following:

=IF(OR(E2="in play",E2="pre play",E2="complete",E2="suspended"),
IF(E2="in play",IF(F2="closed",3,IF(F2="suspended",2,IF(ISBLANK(F2),1,-2))),
IF(E2="pre play",IF(ISBLANK(F2),-1,-2),IF(E2="completed",IF(F2="closed",2,-2),
IF(E2="suspended",IF(ISBLANK(F2),3,-2))))),-2)

When creating subdirectories hanging off from a non-existing parent directory(s) you must pass the -p flag to mkdir ... Please update your Dockerfile with

RUN mkdir -p ... 

I tested this and it's correct.

You can do this:

var getValue  = function (input, defaultValue) {
    return input.value || defaultValue;
};

You might like to try this password breaker.

I was using the Dictionary Attack method. It worked for me because there were only a few combinations to my password that I could think of.

Try adding this to your dependencies:

compile 'org.apache.httpcomponents:httpclient:4.4-alpha1'

And generally if you want to use a library and you are searching for the Gradle dependency line you can use Gradle Please

EDIT: Check this one too.

or

if (StringA.Equals(StringB, StringComparison.CurrentCultureIgnoreCase)) {

but you need to be sure that StringA is not null. So probably better tu use:

string.Equals(StringA , StringB, StringComparison.CurrentCultureIgnoreCase);

Well, I'm late.

In your image, the paper is white, while the background is colored. So, it's better to detect the paper is Saturation(???) channel in HSV color space. Take refer to wiki HSL_and_HSV first. Then I'll copy most idea from my answer in this Detect Colored Segment in an image.

Main steps:

1. Read into BGR
2. Convert the image from bgr to hsv space
3. Threshold the S channel
4. Then find the max external contour(or do Canny, or HoughLines as you like, I choose findContours), approx to get the corners.

This is my result:

The Python code(Python 3.5 + OpenCV 3.3):

#!/usr/bin/python3
# 2017.12.20 10:47:28 CST
# 2017.12.20 11:29:30 CST

import cv2
import numpy as np

##(1) read into  bgr-space
img = cv2.imread("test2.jpg")

##(2) convert to hsv-space, then split the channels
hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
h,s,v = cv2.split(hsv)

##(3) threshold the S channel using adaptive method(`THRESH_OTSU`) or fixed thresh
th, threshed = cv2.threshold(s, 50, 255, cv2.THRESH_BINARY_INV)

##(4) find all the external contours on the threshed S
#_, cnts, _ = cv2.findContours(threshed, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
cnts = cv2.findContours(threshed, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)[-2]

canvas  = img.copy()
#cv2.drawContours(canvas, cnts, -1, (0,255,0), 1)

## sort and choose the largest contour
cnts = sorted(cnts, key = cv2.contourArea)
cnt = cnts[-1]

## approx the contour, so the get the corner points
arclen = cv2.arcLength(cnt, True)
approx = cv2.approxPolyDP(cnt, 0.02* arclen, True)
cv2.drawContours(canvas, [cnt], -1, (255,0,0), 1, cv2.LINE_AA)
cv2.drawContours(canvas, [approx], -1, (0, 0, 255), 1, cv2.LINE_AA)

## Ok, you can see the result as tag(6)
cv2.imwrite("detected.png", canvas)

One of the fundamental principles behind a promise is that it's handled asynchronously. This means that you cannot create a promise and then immediately use its result synchronously in your code (e.g. it's not possible to return the result of a promise from within the function that initiated the promise).

What you likely want to do instead is to return the entire promise itself. Then whatever function needs its result can call .then() on the promise, and the result will be there when the promise has been resolved.

Here is a resource from HTML5Rocks that goes over the lifecycle of a promise, and how its output is resolved asynchronously:
http://www.html5rocks.com/en/tutorials/es6/promises/

This should do when your date is in this format (dd/mm/yyyy).

  sortByDate(arr) {
    arr.sort(function(a,b){
      return Number(new Date(a.readableDate)) - Number(new Date(b.readableDate));
    });

    return arr;
  }

Then call sortByDate(myArr);

Posting another alternative to be more complete. When I tried the "pre" based answers, they added extra vertical line breaks as well.

Each tab can be converted to a sequence non-breaking spaces which require no wrapping.

"    " 

This is not recommended for repeated/extensive use within a page. A div margin/padding approach would appear much cleaner.

It might be easier with vlookup. Try this:

=IFERROR(VLOOKUP(D2,G:H,2,0),"")

The IFERROR() is for no matches, so that it throws "" in such cases.

VLOOKUP's first parameter is the value to 'look for' in the reference table, which is column G and H.

VLOOKUP will thus look for D2 in column G and return the value in the column index 2 (column G has column index 1, H will have column index 2), meaning that the value from column H will be returned.

The last parameter is 0 (or equivalently FALSE) to mean an exact match. That's what you need as opposed to approximate match.

just use this simple code: First add dependency :

implementation 'de.hdodenhof:circleimageview:2.2.0'

then add in xml layout the following code:-

<de.hdodenhof.circleimageview.CircleImageView xmlns:app="http://schemas.android.com/apk/res-auto"
                                        android:id="@+id/Imgshaligram"
                                        android:layout_width="96dp"
                                        android:layout_height="96dp"
                                        android:src="@drawable/shaligram"
                                        app:civ_border_color="#d1b1b1"

                                        android:foregroundGravity="center"/>

  function handle_change(
    evt: React.ChangeEvent<HTMLInputElement>
  ): string {
    evt.persist(); // This is needed so you can actually get the currentTarget
    const inputValue = evt.currentTarget.value;

    return inputValue
  }

And make sure you have "lib": ["dom"] in your tsconfig.

If you want to do this with a Python script instead of having to run C / PHP code, here's a Python3 function that you can use to remove the embedding permissions from the font:

def convert_restricted_font(filename):
with open(filename, 'rb+') as font:

    font.read(12)
    while True:
        _type = font.read(4)
        if not _type:
            raise Exception('Could not read the table definitions of the font.')
        try:
            _type = _type.decode()
        except UnicodeDecodeError:
            pass
        except Exception as err:
            pass
        if _type != 'OS/2':
            continue
        loc = font.tell()
        font.read(4)
        os2_table_pointer = int.from_bytes(font.read(4), byteorder='big')
        length = int.from_bytes(font.read(4), byteorder='big')
        font.seek(os2_table_pointer + 8)

        fs_type = int.from_bytes(font.read(2), byteorder='big')
        print(f'Installable Embedding: {fs_type == 0}')
        print(f'Restricted License: {fs_type & 2}')
        print(f'Preview & Print: {fs_type & 4}')
        print(f'Editable Embedding: {fs_type & 8}')

        print(f'No subsetting: {fs_type & 256}')
        print(f'Bitmap embedding only: {fs_type & 512}')

        font.seek(font.tell()-2)
        installable_embedding = 0 # True
        font.write(installable_embedding.to_bytes(2, 'big'))
        font.seek(os2_table_pointer)
        checksum = 0
        for i in range(length):
            checksum += ord(font.read(1))
        font.seek(loc)
        font.write(checksum.to_bytes(4, 'big'))
        break


if __name__ == '__main__':
    convert_restricted_font("19700-webfont.ttf")

it works, but I ended up solving the problem of loading fonts in IE by https like this this

random.random() gives you a random floating point number in the range [0.0, 1.0) (so including 0.0, but not including 1.0 which is also known as a semi-open range). random.uniform(a, b) gives you a random floating point number in the range [a, b], (where rounding may end up giving you b).

The implementation of random.uniform() uses random.random() directly:

def uniform(self, a, b):
    "Get a random number in the range [a, b) or [a, b] depending on rounding."
    return a + (b-a) * self.random()

random.uniform(0, 1) is basically the same thing as random.random() (as 1.0 times float value closest to 1.0 still will give you float value closest to 1.0 there is no possibility of a rounding error there).

After doing the git rm --cached command, try adding myfile to the .gitignore file (create one if it does not exist). This should tell git to ignore myfile.

The .gitignore file is versioned, so you'll need to commit it and push it to the remote repository.

Lightweight Directory Access Protocol or LDAP, is a standards based specification for interacting with directory data. Directory Services can implement support of LDAP to provide interoperability among 3rd party applications.

Active Directory is Microsoft's implementation of a directory service that, among other protocols, supports LDAP to query it's data.

While it supports LDAP, Active Directory provides a host of extensions and conveniences, such as password expiration and account lockout.

One way that you can do it is creating a new object in the module instead of replacing it.

for example:

var testone = function () {
    console.log('test one');
};
var testTwo = function () {
    console.log('test two');
};
module.exports.testOne = testOne;
module.exports.testTwo = testTwo;

and to call

var test = require('path_to_file').testOne:
testOne();

Like this:

>>> s='1\t2\t3\t4\t5'
>>> [x for x in s.split('\t')]
['1', '2', '3', '4', '5']

For a file:

# create test file:
>>> with open('tabs.txt','w') as o:
...    s='\n'.join(['\t'.join(map(str,range(i,i+10))) for i in [0,10,20,30]])
...    print >>o, s

#read that file:
>>> with open('tabs.txt','r') as f:
...    LoL=[x.strip().split('\t') for x in f]
... 
>>> LoL
[['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'], 
 ['10', '11', '12', '13', '14', '15', '16', '17', '18', '19'], 
 ['20', '21', '22', '23', '24', '25', '26', '27', '28', '29'], 
 ['30', '31', '32', '33', '34', '35', '36', '37', '38', '39']]
>>> LoL[2][3]
23

If you want the input transposed:

>>> with open('tabs.txt','r') as f:
...    LoT=zip(*(line.strip().split('\t') for line in f))
... 
>>> LoT[2][3]
'32'

Or (better still) use the csv module in the default distribution...

I want to start by saying by saying that I realize this question is old and already has an accepted answer; but, as an unfortunate internet user that used this question as a means to end only to be proven wrong shortly after (but not before I upset my client a little) I want to add my thoughts and suggestions.

While @DSG and @Giona are correct, and there is nothing wrong with their answers, there is a creative mechanism you can employ to "get around," so to speak, this limitation. That is not say that I'm condoning circumvention of this feature, quite the contrary, but just some mechanisms so that a user still "feels" as if a video or audio file is "auto playing."

The quick work around is hide a video tag somewhere on the mobile page, since I built a responsive site I only do this for smaller screens. The video tag (HTML and jQuery examples):

HTML

<video id="dummyVideo" src="" preload="none" width="1" height="2"></video>

jQuery

var $dummyVideo = $("<video />", {
  id: "dummyVideo",
  src: "",
  preload: "none",
  width: "1",
  height: "2"
});

With that hidden on the page, when a user "clicks" to watch a movie (still user interaction, there is no way to get around that requirement) instead of navigating to a secondary watch page I load the hidden video. This mainly works because the media tag isn't really used but instead promoted to a Quicktime instance so having a visible video element isn't necessary at all. In the handler for "click" (or "touchend" on mobile).

$(".movie-container").on("click", function() {
  var url = $(this).data("stream-url");
  $dummyVideo.attr("src", url);
  $dummyVideo.get(0).load(); // required if src changed after page load
  $dummyVideo.get(0).play();
});

And viola. As far as UX goes, a user clicks on a video to play and Quicktime opens playing the video they chose. This remains within the limitation that videos can only be played via user action so I'm not forcing data on anyone who isn't deciding to watch a video with this service. I discovered this when trying to figure out how exactly Youtube pulled this off with their mobile which is essentially some really nice Javascript page building and fancy element hiding like in the case of the video tag.

tl;dr Here is a somewhat "workaround" to try and create an "autoplay" UX feature on iOS devices without going above and beyond Apple's limitations and still having users decide if they want to watch a video (or audio most likey, though I've not tested) themselves without having one just loaded without their permission.

Also, to the person who commented that is from sleep.fm, this still unfortunately would not have been a solution to your issues which is time based audio play back.

I hope someone finds this information useful, it would have saved me a week of bad news delivery to a client that was adamant that they have this feature and I was glad to find a way to deliver it in the end.

EDIT

Further finding indicate the above workaround is for iPhone/iPod devices only. The iPad plays video in Safari before it's been full screened so you'll need some mechanism to resize the video on click before playing or else you'll end up with audio and no video.

You should use this

height:auto !important;

Dim proc As New Process()
Dim psi As New ProcessStartInfo()

psi.CreateNoWindow = True
psi.FileName = "cmd.exe"
psi.Arguments = "/C net stop YOURSERVICENAMEHERE && net start YOURSERVICENAMEHERE"
psi.LoadUserProfile = False
psi.UseShellExecute = False
psi.WindowStyle = ProcessWindowStyle.Hidden
proc.StartInfo = psi
proc.Start()

It is really easy to write text on a canvas. It was not clear if you want someone to enter text in the HTML page and then have that text appear on the canvas, or if you were going to use JavaScript to write the information to the screen.

The following code will write some text in different fonts and formats to your canvas. You can modify this as you wish to test other aspects of writing onto a canvas.

 <canvas id="YourCanvasNameHere" width="500" height="500">Canvas not supported</canvas>

 var c = document.getElementById('YourCanvasNameHere');
 var context = c.getContext('2d'); //returns drawing functions to allow the user to draw on the canvas with graphic tools. 

You can either place the canvas ID tag in the HTML and then reference the name or you can create the canvas in the JavaScript code. I think that for the most part I see the <canvas> tag in the HTML code and on occasion see it created dynamically in the JavaScript code itself.

Code:

  var canvas = document.getElementById('myCanvas');
  var context = canvas.getContext('2d');

  context.font = 'bold 10pt Calibri';
  context.fillText('Hello World!', 150, 100);
  context.font = 'italic 40pt Times Roman';
  context.fillStyle = 'blue';
  context.fillText('Hello World!', 200, 150);
  context.font = '60pt Calibri';
  context.lineWidth = 4;
  context.strokeStyle = 'blue';
  context.strokeText('Hello World!', 70, 70);

To do this in Swift3 following is the code:

 let labelSizeWithFixedWith = CGSize(width: 300, height: CGFloat.greatestFiniteMagnitude)
            let exactLabelsize = self.label.sizeThatFits(labelSizeWithFixedWith)
            self.label.frame = CGRect(origin: CGPoint(x: 20, y: 20), size: exactLabelsize)

I'm expecting, as Rohit Vats mentioned in his Comment too, that you have a wrong structure in your DataTable.

Try something like this:

  var t = new DataTable();

  // create column header
  foreach ( string s in identifiders ) {
    t.Columns.Add(new DataColumn(s)); // <<=== i'm expecting you don't have defined any DataColumns, haven't you?
  }

  // Add data to DataTable
  for ( int lineNumber = identifierLineNumber; lineNumber < lineCount; lineNumber++ ) {
    DataRow newRow = t.NewRow();
    for ( int column = 0; column < identifierCount; column++ ) {
      newRow[column] = fileContent.ElementAt(lineNumber)[column];
    }
    t.Rows.Add(newRow);
  }

  return t.DefaultView;

I have used this DataTable in a ValueConverter and it works like a charm with the following binding.

xaml:

 <DataGrid AutoGenerateColumns="True" ItemsSource="{Binding Path=FileContent, Converter={StaticResource dataGridConverter}}" />

So what it does, the ValueConverter transforms my bounded data (what ever it is, in my case it's a List<string[]>) into a DataTable, as the code above shows, and passes this DataTable to the DataGrid. With specified data columns the data grid can generate the needed columns and visualize them.

To say it in a nutshell, in my case the binding to a DataTable works like a charm.

Here, W and H are width and height of input, F are filter dimensions, P is padding size (i.e., number of rows or columns to be padded)

For SAME padding:

For VALID padding:

i it integer, int to Integer

Integer intObj = new Integer(i);

add to collection

list.add(String.valueOf(intObj));

There is no difference in working in both the concepts of assignment to unique_ptr.

int* intPtr = new int(3);
unique_ptr<int> uptr (intPtr);

is similar to

unique_ptr<int> uptr (new int(3));

Here unique_ptr automatically deletes the space occupied by uptr.

how pointers, declared in this way will be different from the pointers declared in a "normal" way.

If you create an integer in heap space (using new keyword or malloc), then you will have to clear that memory on your own (using delete or free respectively).

In the below code,

int* heapInt = new int(5);//initialize int in heap memory
.
.//use heapInt
.
delete heapInt;

Here, you will have to delete heapInt, when it is done using. If it is not deleted, then memory leakage occurs.

In order to avoid such memory leaks unique_ptr is used, where unique_ptr automatically deletes the space occupied by heapInt when it goes out of scope. So, you need not do delete or free for unique_ptr.

Five problems:

1. Don't put a space before or after the equal sign.
2. Use "$(...)" to get the output of a command as text.
3. [ is a command. Put a space between it and the arguments.
4. Commands are case-sensitive. You want echo.
5. Use double quotes around variables. rm "$folderToBeMoved"

I'm adding this answer as a use case and complete example for the runtime-check described in another answer.

This is the approach I've been taking for conveying to the end-user whether the program was compiled as 64-bit or 32-bit (or other, for that matter):

version.h

#ifndef MY_VERSION
#define MY_VERSION

#include <string>

const std::string version = "0.09";
const std::string arch = (std::to_string(sizeof(void*) * 8) + "-bit");

#endif

test.cc

#include <iostream>
#include "version.h"

int main()
{
    std::cerr << "My App v" << version << " [" << arch << "]" << std::endl;
}

Compile and Test

g++ -g test.cc
./a.out
My App v0.09 [64-bit]

driver.get(url) and navigate.to(url) both are used to go to particular web page. The key difference is that driver.get(url): It does not maintain the browser history and cookies and wait till page fully loaded. driver.navigate.to(url):It is also used to go to particular web page.it maintain browser history and cookies and does not wait till page fully loaded and have navigation between the pages back, forward and refresh.

Try GIT_CURL_VERBOSE=1 git push

...Your problem may occur due to proxy settings, for instance if git is trying to reach github.com via a proxy server and the proxy is not responding.

With GIT_CURL_VERBOSE=1 it will show the target IP address and some information. You can compare this IP address with the output of the command: host www.github.com. If these IPs are different then you can set https_proxy="" and try again.

One of the Roslyn engineers who specializes in understanding optimization of stack usage took a look at this and reports to me that there seems to be a problem in the interaction between the way the C# compiler generates local variable stores and the way the JIT compiler does register scheduling in the corresponding x86 code. The result is suboptimal code generation on the loads and stores of the locals.

For some reason unclear to all of us, the problematic code generation path is avoided when the JITter knows that the block is in a try-protected region.

This is pretty weird. We'll follow up with the JITter team and see whether we can get a bug entered so that they can fix this.

Also, we are working on improvements for Roslyn to the C# and VB compilers' algorithms for determining when locals can be made "ephemeral" -- that is, just pushed and popped on the stack, rather than allocated a specific location on the stack for the duration of the activation. We believe that the JITter will be able to do a better job of register allocation and whatnot if we give it better hints about when locals can be made "dead" earlier.

Thanks for bringing this to our attention, and apologies for the odd behaviour.

You can't do it by C#, but you can edit MSIL.

IL code of your Main method:

.method private hidebysig static void Main() cil managed
{
    .entrypoint
    .maxstack 1
    .locals init (
        [0] class MsilEditing.A a)
    L_0000: nop 
    L_0001: newobj instance void MsilEditing.B::.ctor()
    L_0006: stloc.0 
    L_0007: ldloc.0 
    L_0008: callvirt instance void MsilEditing.A::X()
    L_000d: nop 
    L_000e: ret 
}

You should change opcode in L_0008 from callvirt to call

L_0008: call instance void MsilEditing.A::X()

The official way to set the disabled attribute on an HTMLInputElement is this:

var input = document.querySelector('[name="myButton"]');
// Without querySelector API
// var input = document.getElementsByName('myButton').item(0);

// disable
input.setAttribute('disabled', true);
// enable
input.removeAttribute('disabled');

While @kaushar's answer is sufficient for enabling and disabling an HTMLInputElement, and is probably preferable for cross-browser compatibility due to IE's historically buggy setAttribute, it only works because Element properties shadow Element attributes. If a property is set, then the DOM uses the value of the property by default rather than the value of the equivalent attribute.

There is a very important difference between properties and attributes. An example of a true HTMLInputElement property is input.value, and below demonstrates how shadowing works:

var input = document.querySelector('#test');_x000D_
_x000D_
// the attribute works as expected_x000D_
console.log('old attribute:', input.getAttribute('value'));_x000D_
// the property is equal to the attribute when the property is not explicitly set_x000D_
console.log('old property:', input.value);_x000D_
_x000D_
// change the input's value property_x000D_
input.value = "My New Value";_x000D_
_x000D_
// the attribute remains there because it still exists in the DOM markup_x000D_
console.log('new attribute:', input.getAttribute('value'));_x000D_
// but the property is equal to the set value due to the shadowing effect_x000D_
console.log('new property:', input.value);

<input id="test" type="text" value="Hello World" />

That is what it means to say that properties shadow attributes. This concept also applies to inherited properties on the prototype chain:

function Parent() {_x000D_
  this.property = 'ParentInstance';_x000D_
}_x000D_
_x000D_
Parent.prototype.property = 'ParentPrototype';_x000D_
_x000D_
// ES5 inheritance_x000D_
Child.prototype = Object.create(Parent.prototype);_x000D_
Child.prototype.constructor = Child;_x000D_
_x000D_
function Child() {_x000D_
  // ES5 super()_x000D_
  Parent.call(this);_x000D_
_x000D_
  this.property = 'ChildInstance';_x000D_
}_x000D_
_x000D_
Child.prototype.property = 'ChildPrototype';_x000D_
_x000D_
logChain('new Parent()');_x000D_
_x000D_
log('-------------------------------');_x000D_
logChain('Object.create(Parent.prototype)');_x000D_
_x000D_
log('-----------');_x000D_
logChain('new Child()');_x000D_
_x000D_
log('------------------------------');_x000D_
logChain('Object.create(Child.prototype)');_x000D_
_x000D_
// below is for demonstration purposes_x000D_
// don't ever actually use document.write(), eval(), or access __proto___x000D_
function log(value) {_x000D_
  document.write(`<pre>${value}</pre>`);_x000D_
}_x000D_
_x000D_
function logChain(code) {_x000D_
  log(code);_x000D_
_x000D_
  var object = eval(code);_x000D_
_x000D_
  do {_x000D_
    log(`${object.constructor.name} ${object instanceof object.constructor ? 'instance' : 'prototype'} property: ${JSON.stringify(object.property)}`);_x000D_
    _x000D_
    object = object.__proto__;_x000D_
  } while (object !== null);_x000D_
}

I hope this clarifies any confusion about the difference between properties and attributes.

If you happen to use curl and firefox... you could use the cliget add-on which generates a curl call including all authentication mechanisms (aka cookies).

So right click on the raw button cliget->"copy url for link" and then paste that into a shell. You will get your file even if you had to log-in to see it.

Here a small example as response to the title as all mentioned examples are complicated in my opinion as well as the official one.

You should know how to transpile es2015 as well as make your server able to handle the redirect. Here is a snippet for express. More info related to this can be found here.

Make sure to put this below all other routes.

const app = express();
app.use(express.static('distApp'));

/**
 * Enable routing with React.
 */
app.get('*', (req, res) => {
  res.sendFile(path.resolve('distApp', 'index.html'));
});

This is the .jsx file. Notice how the longest path comes first and get's more general. For the most general routes use the exact attribute.

// Relative imports
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter, Route, Switch, Redirect } from 'react-router-dom';

// Absolute imports
import YourReactComp from './YourReactComp.jsx';

const root = document.getElementById('root');

const MainPage= () => (
  <div>Main Page</div>
);

const EditPage= () => (
  <div>Edit Page</div>
);

const NoMatch = () => (
  <p>No Match</p>
);

const RoutedApp = () => (
  <BrowserRouter >
    <Switch>
      <Route path="/items/:id" component={EditPage} />
      <Route exact path="/items" component={MainPage} />          
      <Route path="/yourReactComp" component={YourReactComp} />
      <Route exact path="/" render={() => (<Redirect to="/items" />)} />          
      <Route path="*" component={NoMatch} />          
    </Switch>
  </BrowserRouter>
);

ReactDOM.render(<RoutedApp />, root); 

You create an key with out referer dont enter the referer address

Above points are correct and I want to add some more important points about Static keyword.

Internally what happening when you are using static keyword is it will store in permanent memory(that is in heap memory),we know that there are two types of memory they are stack memory(temporary memory) and heap memory(permanent memory),so if you are not using static key word then will store in temporary memory that is in stack memory(or you can call it as volatile memory).

so you will get a doubt that what is the use of this right???

example: static int a=10;(1 program)

just now I told if you use static keyword for variables or for method it will store in permanent memory right.

so I declared same variable with keyword static in other program with different value.

example: static int a=20;(2 program)

the variable 'a' is stored in heap memory by program 1.the same static variable 'a' is found in program 2 at that time it won`t create once again 'a' variable in heap memory instead of that it just replace value of a from 10 to 20.

In general it will create once again variable 'a' in stack memory(temporary memory) if you won`t declare 'a' as static variable.

overall i can say that,if we use static keyword
  1.we can save memory
  2.we can avoid duplicates
  3.No need of creating object in-order to access static variable with the help of class name you can access it.

the very specific answer to the point is confirm dialogue Js Function:

confirm('Do you really want to do so');

It show dialogue box with ok cancel buttons,to replace these button with yes no is not so simple task,for that you need to write jQuery function.

It is usually handled automatically.

If autodiscovery doesn't work. Edit the elastic search config file, by enabling unicast discovery

Node 1:

    cluster.name: mycluster
    node.name: "node1"
    node.master: true
    node.data: true
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["node1.example.com"]

Node 2:

    cluster.name: mycluster
    node.name: "node2"
    node.master: false
    node.data: true
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["node1.example.com"]

and so on for node 3,4,5. Make node 1 master, and the rest only as data nodes.

Edit: Please note that by ES rule, if you have N nodes, then by convention, N/2+1 nodes should be masters for fail-over mechanisms They may or may not be data nodes, though.

Also, in case auto-discovery doesn't work, most probable reason is because the network doesn't allow it (and therefore disabled). If too many auto-discovery pings take place across multiple servers, the resources to manage those pings will prevent other services from running correctly.

For ex, think of a 10,000 node cluster and all 10,000 nodes doing the auto-pings.

I tried all possible options but result is zero. Finally i found correct solution which is helpful for me. Just go to disable Instant Run Go to File -> Settings -> Build,Execution, Deployment -> Instant Run -> Uncheck the checkbox for instant run. Run your app once and this apk file work properly..

The EclipsePasteAsJavaString plug-in allows you to insert text as a Java string by Ctrl + Shift + V

Example

Paste as usual via Ctrl+V:

some text with tabs and new lines

Paste as Java string via Ctrl+Shift+V

"some text\twith tabs\r\n" + "and new \r\n" + "lines"

If you prefer using column names, you could do something like this as an alternative:

min(data$column_name)

I understand you've solved your issue, but for others reading this thread, here is the answer: you have to increase the stack that your operating system allocates for the python process.

The way to do it, is operating system dependant. In linux, you can check with the command ulimit -s your current value and you can increase it with ulimit -s <new_value>

Try doubling the previous value and continue doubling if it does not work, until you find one that does or run out of memory.

It does appear red on Firefox and IE 8. But perhaps you need to change the border-style too.

.field_set{_x000D_
  border-color: #F00;_x000D_
  border-style: solid;_x000D_
}

<fieldset class="field_set">_x000D_
  <legend>box</legend>_x000D_
  <table width="100%" border="0" cellspacing="0" cellpadding="0">_x000D_
    <tr>_x000D_
      <td>&nbsp;</td>_x000D_
    </tr>_x000D_
  </table>_x000D_
</fieldset>

If you want to know if list element at index i is set or not, you can simply check the following:

if len(l)<=i:
    print ("empty")

If you are looking for something like what is a NULL-Pointer or a NULL-Reference in other languages, Python offers you None. That is you can write:

l[0] = None # here, list element at index 0 has to be set already
l.append(None) # here the list can be empty before
# checking
if l[i] == None:
    print ("list has actually an element at position i, which is None")

Not just only when specify required, I also got this issue when using min and max e.g.

<input type="number" min="1900" max="2090" />

That field can be hidden and shown based on other radio value. So, for temporary solution, I removed the validation.

You can think of these as the opposites of one another.

When you free an area of memory, but still keep a pointer to it, that pointer is dangling:

char *c = malloc(16);
free(c);
c[1] = 'a'; //invalid access through dangling pointer!

When you lose the pointer, but keep the memory allocated, you have a memory leak:

void myfunc()
{
    char *c = malloc(16);
} //after myfunc returns, the the memory pointed to by c is not freed: leak!

OK, two steps to this - first is to write a function that does the translation you want - I've put an example together based on your pseudo-code:

def label_race (row):
   if row['eri_hispanic'] == 1 :
      return 'Hispanic'
   if row['eri_afr_amer'] + row['eri_asian'] + row['eri_hawaiian'] + row['eri_nat_amer'] + row['eri_white'] > 1 :
      return 'Two Or More'
   if row['eri_nat_amer'] == 1 :
      return 'A/I AK Native'
   if row['eri_asian'] == 1:
      return 'Asian'
   if row['eri_afr_amer']  == 1:
      return 'Black/AA'
   if row['eri_hawaiian'] == 1:
      return 'Haw/Pac Isl.'
   if row['eri_white'] == 1:
      return 'White'
   return 'Other'

You may want to go over this, but it seems to do the trick - notice that the parameter going into the function is considered to be a Series object labelled "row".

Next, use the apply function in pandas to apply the function - e.g.

df.apply (lambda row: label_race(row), axis=1)

Note the axis=1 specifier, that means that the application is done at a row, rather than a column level. The results are here:

0           White
1        Hispanic
2           White
3           White
4           Other
5           White
6     Two Or More
7           White
8    Haw/Pac Isl.
9           White

If you're happy with those results, then run it again, saving the results into a new column in your original dataframe.

df['race_label'] = df.apply (lambda row: label_race(row), axis=1)

The resultant dataframe looks like this (scroll to the right to see the new column):

      lname   fname rno_cd  eri_afr_amer  eri_asian  eri_hawaiian   eri_hispanic  eri_nat_amer  eri_white rno_defined    race_label

I gave up the calculations and simply get the size of the view where I want the camera preview displayed and set the camera's preview size the same (just flipped width/height due to rotation) in my custom SurfaceView implementation:

@Override // CameraPreview extends SurfaceView implements SurfaceHolder.Callback { 
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

    Display display = ((WindowManager) getContext().getSystemService(
            Context.WINDOW_SERVICE)).getDefaultDisplay();

    if (display.getRotation() == Surface.ROTATION_0) {
        final Camera.Parameters params = camera.getParameters();
        // viewParams is from the view where the preview is displayed
        params.setPreviewSize(viewParams.height, viewParams.width);
        camera.setDisplayOrientation(90);
        requestLayout();
        camera.setParameters(params);
    }
    // I do not enable rotation, so this can otherwise stay as is
}

Why could you not just do something like this?

class Foo {
  constructor(myObj){
     Object.assign(this, myObj);
  }
  get name() { return this._name; }
  set name(v) { this._name = v; }
}

let foo = new Foo({ name: "bat" });
foo.toJSON() //=> your json ...

All email clients adjust the HTML and the CSS code you provide by their own rules:

e.g.: gmail removes everything but the inner HTML of the body tag.

1. for most other clients you can have a style-tag in your header

<style type="text/css">
    a {text-decoration: none !important;}
</style>

note: don't use CSS comments as YAHOO!Mail might cause trouble.

2. to be on the save side add the same code inline into the A tag as you did and an extra span tag as well (the style rules in a tags get often removed)

<a href="" style="text-decoration: none !important;">
    <span style="text-decoration: none !important;">
        text
    </span>
</a>

If you want the iframe and its contents to scale when the window resizes, you can set the following to the window's resize event as well as the iframes onload event.

function()
{
    var _wrapWidth=$('#wrap').width();
    var _frameWidth=$($('#frame')[0].contentDocument).width();

    if(!this.contentLoaded)
      this.initialWidth=_frameWidth;
    this.contentLoaded=true;
    var frame=$('#frame')[0];

    var percent=_wrapWidth/this.initialWidth;

    frame.style.width=100.0/percent+"%";
    frame.style.height=100.0/percent+"%";

    frame.style.zoom=percent;
    frame.style.webkitTransform='scale('+percent+')';
    frame.style.webkitTransformOrigin='top left';
    frame.style.MozTransform='scale('+percent+')';
    frame.style.MozTransformOrigin='top left';
    frame.style.oTransform='scale('+percent+')';
    frame.style.oTransformOrigin='top left';
  };

This will make the iframe and its content scale to 100% width of the wrap div (or whatever percent you want). As an added bonus, you don't have to set the css of the frame to hard coded values since they'll all be set dynamically, you'll just need to worry about how you want the wrap div to display.

I've tested this and it works on chrome, IE11, and firefox.

You can use LINQ for this

var list = new List<int>();
var sum = list.Sum();

and for a List of strings like Roy Dictus said you have to convert

list.Sum(str => Convert.ToInt32(str));

"ModelState.IsValid" tells you that the model is consumed by the view (i.e. PaymentAdviceEntity) is satisfy all types of validation or not specified in the model properties by DataAnotation.

In this code the view does not bind any model properties. So if you put any DataAnotations or validation in model (i.e. PaymentAdviceEntity). then the validations are not satisfy. say if any properties in model is Name which makes required in model.Then the value of the property remains blank after post.So the model is not valid (i.e. ModelState.IsValid returns false). You need to remove the model level validations.

In command mode (press Esc if you are not sure) you can use:

• gg,
• :1,
• 1G,
• or 1gg.

<div id="item">show taille height</div>
<script>
    alert(document.getElementById('item').offsetHeight);
</script>

DO NOT use this:

System.Environment.GetEnvironmentVariable("TEMP")

Environment variables can be overridden, so the TEMP variable is not necessarily the directory.

The correct way is to use System.IO.Path.GetTempPath() as in the accepted answer.

2014 March: Truncating long strings with CSS: a new answer with focus on browser support

Demo on http://jsbin.com/leyukama/1/ (I use jsbin because it supports old version of IE).

<style type="text/css">
    span {
        display: inline-block;
        white-space: nowrap;
        overflow: hidden;
        text-overflow: ellipsis;     /** IE6+, Firefox 7+, Opera 11+, Chrome, Safari **/
        -o-text-overflow: ellipsis;  /** Opera 9 & 10 **/
        width: 370px; /* note that this width will have to be smaller to see the effect */
    }
</style>

<span>Some very long text that should be cut off at some point coz it's a bit too long and the text overflow ellipsis feature is used</span>

The -ms-text-overflow CSS property is not necessary: it is a synonym of the text-overflow CSS property, but versions of IE from 6 to 11 already support the text-overflow CSS property.

Successfully tested (on Browserstack.com) on Windows OS, for web browsers:

• IE6 to IE11
• Opera 10.6, Opera 11.1, Opera 15.0, Opera 20.0
• Chrome 14, Chrome 20, Chrome 25
• Safari 4.0, Safari 5.0, Safari 5.1
• Firefox 7.0, Firefox 15

Firefox: as pointed out by Simon Lieschke (in another answer), Firefox only support the text-overflow CSS property from Firefox 7 onwards (released September 27th 2011).

I double checked this behavior on Firefox 3.0 & Firefox 6.0 (text-overflow is not supported).

Some further testing on a Mac OS web browsers would be needed.

Note: you may want to show a tooltip on mouse hover when an ellipsis is applied, this can be done via javascript, see this questions: HTML text-overflow ellipsis detection and HTML - how can I show tooltip ONLY when ellipsis is activated

This depends on where you want the error message be stored.

You can do the following:

echo "Error!" > logfile.log
exit 125

Or the following:

echo "Error!" 1>&2
exit 64

When you raise an exception you stop the program's execution.

You can also use something like exit xxx where xxx is the error code you may want to return to the operating system (from 0 to 255). Here 125 and 64 are just random codes you can exit with. When you need to indicate to the OS that the program stopped abnormally (eg. an error occurred), you need to pass a non-zero exit code to exit.

As @chepner pointed out, you can do exit 1, which will mean an unspecified error.

First you should try with Proguard (This clean all code unused)

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

In my understanding, Get-Content eliminates ALL newlines/carriage returns when it rolls your text file through the pipeline. To do multiline regexes, you have to re-combine your string array into one giant string. I do something like:

$text = [string]::Join("`n", (Get-Content test.txt))
[regex]::Replace($text, "t`n", "ting`na ", "Singleline")

Clarification: small files only folks! Please don't try this on your 40 GB log file :)

Probably too late for an answere but, try this one

Get-Content <filename> -tail <number of items wanted>

If you want to execute that command, you should probably change:

PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'

to:

PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)

You do realize this is the default behavior, right? if you add /something the results would be different.

you can do a number of things to prevent default behavior.

href="#":

Will do nothing but anchor - not the best solution since it may jump to page top.

<a href="#">

href="javascript:void(0);"

Will do nothing at all and is perfectly legit.

<a href="javascript:void(0);"></a>

href="your-actual-intended-link" (Best)

obviously the best.

<a href="<your-actual-intended-link>"></a>

If you don't want an a tag to go somewhere, why use an a tag at all?

use DateTime.Now

try this:

DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

   $('.modal').on('shown.bs.modal', function (e) {
      $('body').css('overflow-y', 'hidden');
   });
   $('.modal').on('hidden.bs.modal', function (e) {
      $('body').css('overflow-y', '');
   });

Really the ideal way to do this is to not use pull at all, but instead fetch and reset:

git fetch origin master
git reset --hard FETCH_HEAD
git clean -df

(Altering master to whatever branch you want to be following.)

pull is designed around merging changes together in some way, whereas reset is designed around simply making your local copy match a specific commit.

You may want to consider slightly different options to clean depending on your system's needs.

Well guys, the solution to the problem is the following:

1. click in: Start
2. write the word: ejecut
3. After, write: regedit
4. Open the directory: HKEY_LOCAL_MACHINE
5. SOFTWARE
6. Microsoft
7. Windows NT
8. CurrentVersion
9. Perflib
10. Check the following things:

1) Folder 00A: 2) Counter: the last number 3) Help: the last number

   Folder Perflib:
   Last Counter: 00A folder´s Counter 
   Last Help: 00A folder´s Help

Ready, verify the same number in both. success

$this->db->select('*');    
$this->db->from('table1');
$this->db->join('table2', 'table1.id = table2.id','JOIN Type');
$this->db->join('table3', 'table1.id = table3.id');
$query = $this->db->get();

this will give you result from table1,table2,table3 and you can use any type of join in the third variable of $this->db->join() function such as inner,left, right etc.

Under "Start" enter "environment" in the search field. That will list the option to change the system variables directly in the start menu.

Try using the "%h" modifier:

scanf("%hu", &length);
        ^

ISO/IEC 9899:201x - 7.21.6.1-7

Specifies that a following d , i , o , u , x , X , or n conversion specifier applies to an argument with type pointer to short or unsigned short.

You could try the subplot_tool()

plt.subplot_tool()

(int)Math.Round(myNumber, 0)

Try the different values for Graphics.InterpolationMode. There are several typical scaling algorithms available in GDI+. If one of these is sufficient for your need, you can go this route instead of relying on an external library.

You can use find_package to search for available boost libraries. It defers searching for Boost to FindBoost.cmake, which is default installed with CMake.

Upon finding Boost, the find_package() call will have filled many variables (check the reference for FindBoost.cmake). Among these are BOOST_INCLUDE_DIRS, Boost_LIBRARIES and Boost_XXX_LIBRARY variabels, with XXX replaced with specific Boost libraries. You can use these to specify include_directories and target_link_libraries.

For example, suppose you would need boost::program_options and boost::regex, you would do something like:

find_package( Boost REQUIRED COMPONENTS program_options regex )
include_directories( ${Boost_INCLUDE_DIRS} )
add_executable( run main.cpp ) # Example application based on main.cpp

# Alternatively you could use ${Boost_LIBRARIES} here.
target_link_libraries( run ${Boost_PROGRAM_OPTIONS_LIBRARY} ${Boost_REGEX_LIBRARY} )

Some general tips:

• When searching, FindBoost checks the environment variable $ENV{BOOST_ROOT}. You can set this variable before calling find_package if necessary.
• When you have multiple build-versions of boost (multi-threaded, static, shared, etc.) you can specify you desired configuration before calling find_package. Do this by setting some of the following variables to On: Boost_USE_STATIC_LIBS, Boost_USE_MULTITHREADED, Boost_USE_STATIC_RUNTIME
• When searching for Boost on Windows, take care with the auto-linking. Read the "NOTE for Visual Studio Users" in the reference.
  • My advice is to disable auto-linking and use cmake's dependency handling: add_definitions( -DBOOST_ALL_NO_LIB )
  • In some cases, you may need to explicitly specify that a dynamic Boost is used: add_definitions( -DBOOST_ALL_DYN_LINK )

I have the same issue, I'm not able to open a CSV file in Excel. I've found a solution that worked for me in this question Opening a file in excel via Workbooks.OpenText

That question helped me to figure out a code that works for me. The code looks more or less like this:

Private Sub OpenCSVFile(filename as String)
    Dim datasourceFilename As String
    Dim currentPath As String

    datasourceFilename = "\" & filename & ".csv"
    currentPath = ActiveWorkbook.Path

    Workbooks.OpenText Filename:=currentPath & datasourceFilename, _
                       Origin:=xlWindows, _
                       StartRow:=1, _
                       DataType:=xlDelimited, _
                       TextQualifier:=xlDoubleQuote, _
                       ConsecutiveDelimiter:=False, _
                       Tab:=False, _
                       Semicolon:=False, _
                       Comma:=True, _
                       Space:=False, _
                       Other:=False, _
                       FieldInfo:=Array(Array(1, 1), Array(2, 1)), _
                       DecimalSeparator:=".", _
                       ThousandsSeparator:=",", _
                       TrailingMinusNumbers:=True
End Sub

At least, it helped me to know about lots of parameters I can use with Workbooks.OpenText method.

Here is my answer using the group by clause.

SELECT *
FROM feeds f
LEFT JOIN 
(
    SELECT artist_id, feed_id
    FROM feeds_artists
    GROUP BY artist_id, feed_id 
) fa ON fa.feed_id = f.id
LEFT JOIN artists a ON a.artist_id = fa.artist_id

Visual Studio For Mac

None of the other solutions worked on Visual Studio for Mac

If you are using NUnit, you can add a small .NET Console Project to your solution, and then reference the project you wish to test in the References of that new Console Project.

Whatever you were doing in your [Test()] methods can be done in the Main of the console application in this fashion:

class MainClass
{
    public static void Main(string[] args)
    {
        Console.WriteLine("Console");

        // Reproduce the unit test
        var classToTest = new ClassToTest();
        var expected = 42;
        var actual = classToTest.MeaningOfLife();
        Console.WriteLine($"Pass: {expected.Equals(actual)}, expected={expected}, actual={actual}");
    }
}

You are free to use Console.Write and Console.WriteLine in your code under these circumstances.

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

Have you tried looking at your %PATH% variable. That's what Windows uses to find any executable.

For angular 4 I have used

<img [src]="data.pic ? data.pic : 'assets/images/no-image.png' " alt="Image" title="Image">

It works for me , I hope it may use to other's also for Angular 4-5. :)

This is the ASCII format.

Please consider that:

Some data (like URLs) can be sent over the Internet using the ASCII character-set. Since data often contain characters outside the ASCII set, so it has to be converted into a valid ASCII format.

To find it yourself, you can visit https://en.wikipedia.org/wiki/ASCII, there you can find big tables of characters. The one you are looking is in Control Characters table.

Digging to table you can find

Oct Dec Hex Name 012 10 0A Line Feed

In the html file you can use Dec and Hex representation of charters

The Dec is represented with 


The Hex is represented with &#x0A (or you can omit the leading zero &#xA)

There is a good converter at https://r12a.github.io/apps/conversion/ .

Since the quickest, shortest answer is in a comment (from Jeff) and has a typo, here it is corrected and in full:

sales['time_hour'] = pd.DatetimeIndex(sales['timestamp']).hour

A solution using mutate_all from dplyr in case you want to add that to your dplyr pipeline:

library(dplyr)
df %>%
  mutate_all(funs(ifelse(is.na(.), 0, .)))

Result:

   A B C
1  0 0 0
2  1 0 0
3  2 0 2
4  3 0 5
5  0 0 2
6  0 0 1
7  1 0 1
8  2 0 5
9  3 0 2
10 0 0 4
11 0 0 3
12 1 0 5
13 2 0 5
14 3 0 0
15 0 0 1

If in any case you only want to replace the NA's in numeric columns, which I assume it might be the case in modeling, you can use mutate_if:

library(dplyr)
df %>%
  mutate_if(is.numeric, funs(ifelse(is.na(.), 0, .)))

or in base R:

replace(is.na(df), 0)

Result:

   A    B C
1  0    0 0
2  1 <NA> 0
3  2    0 2
4  3 <NA> 5
5  0    0 2
6  0 <NA> 1
7  1    0 1
8  2 <NA> 5
9  3    0 2
10 0 <NA> 4
11 0    0 3
12 1 <NA> 5
13 2    0 5
14 3 <NA> 0
15 0    0 1

Update

with dplyr 1.0.0, across is introduced:

library(dplyr)
# Replace `NA` for all columns
df %>%
  mutate(across(everything(), ~ ifelse(is.na(.), 0, .)))

# Replace `NA` for numeric columns
df %>%
  mutate(across(where(is.numeric), ~ ifelse(is.na(.), 0, .)))

Data:

set.seed(123)
df <- data.frame(A=rep(c(0:3, NA), 3), 
                 B=rep(c("0", NA), length.out = 15), 
                 C=sample(c(0:5, NA), 15, replace = TRUE))

It depends on what is your backend technology. If your backend technology accepting JSON data. data:{id:1,name:'name',...}

otherwise, you need to convert your data best way to do that creating Factory to convert your data to id=1&name=name&...

then on $http define content-type. you can find full article @https://www.bennadel.com/blog/2615-posting-form-data-with-http-in-angularjs.htm

$http({
    method: 'POST',
    url: url,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    transformRequest: function(obj) {
        var str = [];
        for(var p in obj)
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
        return str.join("&");
    },
    data: {username: $scope.userName, password: $scope.password}
}).success(function () {});

ref:How do I POST urlencoded form data with $http in AngularJS?

!important about encodeURIComponent(obj[p]) will transfer object the way implicit. like a date value will be converted to a string like=>'Fri Feb 03 2017 09:56:57 GMT-0700 (US Mountain Standard Time)' which I don't have any clue how you can parse it at least in back-end C# code. (I mean code that doesn't need more than 2-line) you can use (angular.isDate, value.toJSON) in date case to convert it to more meaningful format for your back-end code.

I'm using this function to comunicating to my backend webservices...

 this.SendUpdateRequest = (url, data) => {
            return $http({
                method: 'POST',
                url: url,
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
                transformRequest: function (obj) { return jsontoqs(obj); },
                data: { jsonstring: JSON.stringify(data) }
            });
        }; 

and bellow code to use it...

webrequest.SendUpdateRequest(
  '/Services/ServeicNameWebService.asmx/Update',
  $scope.updatedto)
  .then(
      (res) => { /*/TODO/*/ },
      (err) => { /*/TODO/*/ }
);

in backend C# I'm using newtonsoft for deserializing the data.

Please try selecting the password field like this.

    WebDriverWait wait = new WebDriverWait(driver, 10);
    WebElement passwordElement = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("#Passwd")));
    passwordElement.click();
  passwordElement.clear();
     passwordElement.sendKeys("123");

First you'll need to get it into a byte[], so do this:

byte[] ba = Encoding.Default.GetBytes("sample");

and then you can get the string:

var hexString = BitConverter.ToString(ba);

now, that's going to return a string with dashes (-) in it so you can then simply use this:

hexString = hexString.Replace("-", "");

to get rid of those if you want.

NOTE: you could use a different Encoding if you needed to.

Here a very simple but effective code using cElementTree.

try:
    import cElementTree as ET
except ImportError:
  try:
    # Python 2.5 need to import a different module
    import xml.etree.cElementTree as ET
  except ImportError:
    exit_err("Failed to import cElementTree from any known place")      

def find_in_tree(tree, node):
    found = tree.find(node)
    if found == None:
        print "No %s in file" % node
        found = []
    return found  

# Parse a xml file (specify the path)
def_file = "xml_file_name.xml"
try:
    dom = ET.parse(open(def_file, "r"))
    root = dom.getroot()
except:
    exit_err("Unable to open and parse input definition file: " + def_file)

# Parse to find the child nodes list of node 'myNode'
fwdefs = find_in_tree(root,"myNode")

This is from "python xml parse".

May be using two br tags is the simplest solution that works with all browsers. But it is repetitive.

<p>
content
</p>
<br /><br />
<p>
content
</p>
<br /><br />
<p>
content
</p>

maybe you can try using

SELECT user_name
FROM user_master
WHERE upper(user_name) LIKE '%ME%'

Edit: New article by Dave Abrahams on cpp-next:

Want speed? Pass by value.

Pass by value for structs where the copying is cheap has the additional advantage that the compiler may assume that the objects don't alias (are not the same objects). Using pass-by-reference the compiler cannot assume that always. Simple example:

foo * f;

void bar(foo g) {
    g.i = 10;
    f->i = 2;
    g.i += 5;
}

the compiler can optimize it into

g.i = 15;
f->i = 2;

since it knows that f and g doesn't share the same location. if g was a reference (foo &), the compiler couldn't have assumed that. since g.i could then be aliased by f->i and have to have a value of 7. so the compiler would have to re-fetch the new value of g.i from memory.

For more pratical rules, here is a good set of rules found in Move Constructors article (highly recommended reading).

• If the function intends to change the argument as a side effect, take it by non-const reference.
• If the function doesn't modify its argument and the argument is of primitive type, take it by value.
• Otherwise take it by const reference, except in the following cases
  • If the function would then need to make a copy of the const reference anyway, take it by value.

"Primitive" above means basically small data types that are a few bytes long and aren't polymorphic (iterators, function objects, etc...) or expensive to copy. In that paper, there is one other rule. The idea is that sometimes one wants to make a copy (in case the argument can't be modified), and sometimes one doesn't want (in case one wants to use the argument itself in the function if the argument was a temporary anyway, for example). The paper explains in detail how that can be done. In C++1x that technique can be used natively with language support. Until then, i would go with the above rules.

Examples: To make a string uppercase and return the uppercase version, one should always pass by value: One has to take a copy of it anyway (one couldn't change the const reference directly) - so better make it as transparent as possible to the caller and make that copy early so that the caller can optimize as much as possible - as detailed in that paper:

my::string uppercase(my::string s) { /* change s and return it */ }

However, if you don't need to change the parameter anyway, take it by reference to const:

bool all_uppercase(my::string const& s) { 
    /* check to see whether any character is uppercase */
}

However, if you the purpose of the parameter is to write something into the argument, then pass it by non-const reference

bool try_parse(T text, my::string &out) {
    /* try to parse, write result into out */
}

In my case it wasn't changing the color because I was setting the color in my xml resource.

After delete the line that set the color it worked perfectly programmatically

This is an example I did in a RecyclerView

final Drawable drawable = ContextCompat.getDrawable(mContext, R.drawable.ic_icon).mutate();

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
    holder.image.setBackground(drawable);
} else {
    holder.image.setBackgroundDrawable(drawable);
}

h3 is absolutly a better solution than h2, h1 or h6 !

1. You have to use specific level : if you're in a h1, use h2, if you're in a h5, use h6 (if you're in a h6... hum, use strong or em for exemple). It not a obligation but a question of accessibility (Here, green part).

2. You don't have to give title to list... because this element it doesn't exist. So screen reader will not use something special.

Therefore, using Hn is probably one of the best solution, but surely not a specific level.

Well, since the date of this question post, a Python library addressed this topic. pynput library, from Moses Palmer, is GREAT to catch keyboard and mouse events in a very simple way.

• GitHub repository is here: https://github.com/moses-palmer/pynput
• PyPi project is there: enter link description here
• and installation of lib is easy: 'pip install pynput'

(mind the missing 'i' in pynput - I missed it too... ;-) )

I happen to miss spaces in my query and this error comes.

Ex: $sql= "SELECT * FROM";
$sql .= "table1";

Though the example might look simple, when coding complex queries, the probability for this error is high. I was missing space before word "table1".

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

Two ways I've used it... first:

SET /P variable=

When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.

And second:

SET /P variable=<%temp%\filename.txt

Will set variable to contents (the first line) of the txt file. This method won't work unless the /P is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.

ID  VALUE1  VALUE2
===================
1   1       2

1   2       2
2   3       4
2   4       5

select ID, (coalesce(VALUE1 ,0) + coalesce(VALUE2 ,0) as Total from TableName

Are you talking about when you click on an input box, rather than just hover over it? This fixed it for me:

input:focus {
   outline: none;
   border: specify yours;
}

This is a simple way to call notification by using default vibrate and sound from system.

private void sendNotification(String message, String tick, String title, boolean sound, boolean vibrate, int iconID) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);
    Notification notification = new Notification();

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);

    if (sound) {
        notification.defaults |= Notification.DEFAULT_SOUND;
    }

    if (vibrate) {
        notification.defaults |= Notification.DEFAULT_VIBRATE;
    }

    notificationBuilder.setDefaults(notification.defaults);
    notificationBuilder.setSmallIcon(iconID)
            .setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(true)
            .setTicker(tick)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

Add vibrate permission if you are going to use it:

<uses-permission android:name="android.permission.VIBRATE"/>

Good luck,'.

It depends a bit on your version. Before 5.0.13 this is not possible with mysqldump.

From the mysqldump man page (v 5.1.30)

 --routines, -R

      Dump stored routines (functions and procedures) from the dumped
      databases. Use of this option requires the SELECT privilege for the
      mysql.proc table. The output generated by using --routines contains
      CREATE PROCEDURE and CREATE FUNCTION statements to re-create the
      routines. However, these statements do not include attributes such
      as the routine creation and modification timestamps. This means that
      when the routines are reloaded, they will be created with the
      timestamps equal to the reload time.
      ...

      This option was added in MySQL 5.0.13. Before that, stored routines
      are not dumped. Routine DEFINER values are not dumped until MySQL
      5.0.20. This means that before 5.0.20, when routines are reloaded,
      they will be created with the definer set to the reloading user. If
      you require routines to be re-created with their original definer,
      dump and load the contents of the mysql.proc table directly as
      described earlier.

For those, who wonder how it goes in VS.

MSVC 2015 Update 1, cl.exe version 19.00.24215.1:

#include <iostream>

template<typename X, typename Y>

output:

Using of __PRETTY_FUNCTION__ triggers undeclared identifier error, as expected.

To understand "this" properly one must understand the context and scope and difference between them.

Scope: In javascript scope is related to the visibility of the variables, scope achieves through the use of the function. (Read more about scope)

Context: Context is related to objects. It refers to the object to which a function belongs. When you use the JavaScript “this” keyword, it refers to the object to which function belongs. For example, inside of a function, when you say: “this.accoutNumber”, you are referring to the property “accoutNumber”, that belongs to the object to which that function belongs.

If the object “myObj” has a method called “getMyName”, when the JavaScript keyword “this” is used inside of “getMyName”, it refers to “myObj”. If the function “getMyName” were executed in the global scope, then “this” refers to the window object (except in strict mode).

Now let's see some example:

    <script>
        console.log('What is this: '+this);
        console.log(this);
    </script>

Runnig abobve code in browser output will:

According to the output you are inside of the context of the window object, it is also visible that window prototype refers to the Object.

Now let's try inside of a function:

    <script>
        function myFunc(){
            console.log('What is this: '+this);
            console.log(this);
        }
        myFunc();
    </script>

Output:

The output is the same because we logged 'this' variable in the global scope and we logged it in functional scope, we didn't change the context. In both case context was same, related to widow object.

Now let's create our own object. In javascript, you can create an object in many ways.

 <script>
        var firstName = "Nora";
        var lastName = "Zaman";
        var myObj = {
            firstName:"Lord",
            lastName:'Baron',
            printNameGetContext:function(){
                console.log(firstName + " "+lastName);
                console.log(this.firstName +" "+this.lastName);
                return this;
            }
        }

      var context = myObj.printNameGetContext();
      console.log(context);
    </script>

Output:

So from the above example, we found that 'this' keyword is referring to a new context that is related to myObj, and myObject also has prototype chain to Object.

Let's go throw another example:

<body>
    <button class="btn">Click Me</button>
    <script>
        function printMe(){
            //Terminal2: this function declared inside window context so this function belongs to the window object.
            console.log(this);
        }
        document.querySelector('.btn').addEventListener('click', function(){
            //Terminal1: button context, this callback function belongs to DOM element 
            console.log(this);
            printMe();
        })
    </script>
</body>

output: Make sense right? (read comments)

If you having trouble to understand the above example let's try with our own callback;

<script>
        var myObj = {
            firstName:"Lord",
            lastName:'Baron',
            printName:function(callback1, callback2){
                //Attaching callback1 with this myObj context
                this.callback1 = callback1;
                this.callback1(this.firstName +" "+this.lastName)
                //We did not attached callback2 with myObj so, it's reamin with window context by default
                callback2();
                /*
                 //test bellow codes
                 this.callback2 = callback2;
                 this.callback2();
                */
            }
        }
        var callback2 = function (){
            console.log(this);
        }
        myObj.printName(function(data){
            console.log(data);
            console.log(this);
        }, callback2);
    </script>

output:

Now let's Understand Scope, Self, IIFE and THIS how behaves

       var color = 'red'; // property of window
       var obj = {
           color:'blue', // property of window
           printColor: function(){ // property of obj, attached with obj
               var self = this;
               console.log('In printColor -- this.color: '+this.color);
               console.log('In printColor -- self.color: '+self.color);
               (function(){ // decleard inside of printColor but not property of object, it will executed on window context.
                    console.log(this)
                    console.log('In IIFE -- this.color: '+this.color);
                    console.log('In IIFE -- self.color: '+self.color); 
               })();

               function nestedFunc(){// decleard inside of printColor but not property of object, it will executed on window context.
                    console.log('nested fun -- this.color: '+this.color);
                    console.log('nested fun -- self.color: '+self.color);
               }

               nestedFunc(); // executed on window context
               return nestedFunc;
           }
       };

       obj.printColor()(); // returned function executed on window context
   </script> 

Output is pretty awesome right?

Adding to what deceze said above. This is a parse error, so in order to debug a parse error, create a new file in the root named debugSyntax.php. Put this in it:

<?php

///////    SYNTAX ERROR CHECK    ////////////
error_reporting(E_ALL);
ini_set('display_errors','On');

//replace "pageToTest.php" with the file path that you want to test. 
include('pageToTest.php'); 

?>

Run the debugSyntax.php page and it will display parse errors from the page that you chose to test.

I'd probably change your example to look like this:

<ul ng-repeat="task in tasks">
  <li ng-mouseover="enableEdit(task)" ng-mouseleave="disableEdit(task)">{{task.name}}</li>
  <span ng-show="task.editable"><a>Edit</a></span>
</ul>

//js
$scope.enableEdit = function(item){
  item.editable = true;
};

$scope.disableEdit = function(item){
  item.editable = false;
};

I know it's a subtle difference, but makes the domain a little less bound to UI actions. Mentally it makes it easier to think about an item being editable rather than having been moused over.

Handling the exception is the way to go:

try:
    gotdata = dlist[1]
except IndexError:
    gotdata = 'null'

Of course you could also check the len() of dlist; but handling the exception is more intuitive.

SMS Push uses SMS as a carrier, WAP uses download via WAP.

1. Go to the site-packages directory where pip is installing your packages.
2. You should see the egg file that corresponds to the package you want to uninstall. Delete the egg file (or, to be on the safe side, move it to a different directory).
3. Do the same with the package files for the package you want to delete (in this case, the psycopg2 directory).
4. pip install YOUR-PACKAGE

One thing I want to add. Sometimes, there can be precision loss. You may want to add some epsilon value first before converting. Not sure why that works... but it work.

int someint = (somedouble+epsilon);

This trick worked for me (for min-sdk >= 18).

I used android:includeFontPadding="false" and a negative margin like android:layout_marginTop="-11dp" and put my TextView inside a FrameLayout ( or any ViewGroup...)

and finally sample codes:

<LinearLayout
    android:layout_width="60dp"
    android:layout_height="wrap_content"
    >

    <TextView
        style="@style/MyTextViews.Bold"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/yellow"
        android:textSize="48sp"
        android:layout_marginTop="-11dp"
        android:includeFontPadding="false"
        tools:text="1"/>
</LinearLayout>

You can easily increase your VM's RAM by modifying the memory property of config.vm.provider section in your vagrant file.

config.vm.provider "virtualbox" do |vb|
 vb.memory = "4096"
end

This allocates about 4GB of RAM to your VM. You can change this according to your requirement. For example, following setting would allocate 2GB of RAM to your VM.

config.vm.provider "virtualbox" do |vb|
 vb.memory = "2048"
end

Try removing the config.vm.customize ["modifyvm", :id, "--memory", 1024] in your file, and adding the above code.

For the network configuration, try modifying the config.vm.network :hostonly, "199.188.44.20" in your file toconfig.vm.network "private_network", ip: "199.188.44.20"

By default the navigation controller displays the title of the 'topitem'

so in your viewdidload method of your appdelegate you can. I tested it and it works

navController.navigationBar.topItem.title = @"Test";

First of all, the space complexity of this loop is O(1) (the input is customarily not included when calculating how much storage is required by an algorithm).

So the question that I have is if its possible that an algorithm has different time complexity from space complexity?

Yes, it is. In general, the time and the space complexity of an algorithm are not related to each other.

Sometimes one can be increased at the expense of the other. This is called space-time tradeoff.

Just stick with the virtual machine: If you're running Internet Explorer 8 you'll be able to activate the developer window using F12. There you're able to edit CSS as well as HTML on the fly without saving/reloading the page.

In addition to the fine answers above, I think it should be said that Tomcat has it's own HTTP server built into it, and is fully functional at serving static content too. Depending on your java virtual machine configuration it can actually outperform going through traditional connectors in apache such as mod_proxy and mod_jk.

That said a fully optimized Tomcat server should serve static files fast and if you have Java servlets, JSPs and ColdFusion files in addition to static content you may find tomcat does an excellent job by itself.

the best way to concat props/variables:

var sample = "test";    
var result = `this is just a ${sample}`;    
//this is just a test

let array = [5,5,4,4,2,3,4]    
let newArray = array.join(',').replace('5','').split(',')

This example works if you want to remove one current item.

Boundary Control Entity pattern have two versions:
- old structural, described at 127 (entity as an data model elements, control as an functions, boundary as an application interface)
- new object pattern


As an object pattern:
- Boundary is an interface for "other world"
- Control in an any internal logic (like a service in DDD pattern)
- Entity is an an persistence serwis for objects (like a repository in DDD pattern).
All classes have operations (see Fowler anemic domain model anti-pattern)
All of them is an Model component in MVC pattern. The rules:
- Only Boundary provide services for the "other world"
- Boundary can call only to Controll
- Control can call anybody
- Entity can't call anybody (!), only be called.

Use git show:

git show --summary

This will show the names of created or removed files, but not the names of changed files. The git show command supports a wide variety of output formats that show various types of information about commits.

On Mac OS X with Homebrew, as obviously, PHP is already installed due to provided error we cannot run:

Update: Tha latest version brew instal php --with-imap will not work any more!!!

$ brew install php72 --with-imap
Warning: homebrew/php/php72 7.2.xxx is already installed

Also, installing module only, here will not work:

$ brew install php72-imap
Error: No available formula with the name "php72-imap"

So, we must reinstall it:

$ brew reinstall php72 --with-imap

It will take a while :-) (built in 8 minutes 17 seconds)

It does it:

myString.substr(-1);

This returns a substring of myString starting at one character from the end: the last character.

This also works:

myString.charAt(myString.length-1);

And this too:

myString.slice(-1);

just use jQuery bind method !jquery-selector!.bind('event', !fn!);

See here for more about events in jQuery

Sometimes you just want a simple one liner:

binary = ''.join(['{0:08b}'.format(ord(x)) for x in input])

Python 3

Use the following simple example

function scrollToElement(ele) {
    $(window).scrollTop(ele.offset().top).scrollLeft(ele.offset().left);
}

where ele is your element (jQuery) .. for example : scrollToElement($('#myid'));

In MySQL -> INT(10) does not mean a 10-digit number, it means an integer with a display width of 10 digits. The maximum value for an INT in MySQL is 2147483647 (or 4294967295 if unsigned).

You can use a BIGINT instead of INT to store it as a numeric. Using BIGINT will save you 3 bytes per row over VARCHAR(10).

If you want to Store "Country + area + number separately". Try using a VARCHAR(20). This allows you the ability to store international phone numbers properly, should that need arise.

This is a particularly great way to do this (you can get max of an array of objects using one of the object properties): Math.max.apply(Math,array.map(function(o){return o.y;}))

This is the accepted answer for this page: Finding the max value of an attribute in an array of objects

I solved this problem by below step,

1) go to -> system environment -> Environment Variables -> system Variable

2) create New Variable Name ANDROID_HOME and Value D:\Androidsdk\tools (custom android sdk path).

3) concat this path D:\Androidsdk\platform-tools in Path variable value using ";". (also in system Variable)

4) that's all, Restart the PC to apply changes and try again -- flutter Doctor.

Created something generic to use on any HTML element

HTMLElement.prototype.printMe = printMe;
function printMe(query){             
     var myframe = document.createElement('IFRAME');
     myframe.domain = document.domain;
     myframe.style.position = "absolute";
     myframe.style.top = "-10000px";
     document.body.appendChild(myframe);
     myframe.contentDocument.write(this.innerHTML) ;
     setTimeout(function(){
        myframe.focus();
        myframe.contentWindow.print();
        myframe.parentNode.removeChild(myframe) ;// remove frame
     },3000); // wait for images to load inside iframe
     window.focus();
}
//usage
document.getElementById('xyz').printMe();
document.getElementsByClassName('xyz')[0].printMe();

Hope this helps.

In build.gradle add wrapper { gradleVersion = '6.0' }

This should help,

 String s = "This is a sample sentence";
 String[] words = s.split(" ");

this will make an array with elements as the string separated by " ".

It is another type of layer, so you should add it as a layer in an appropriate place of your model

model.add(keras.layers.normalization.BatchNormalization())

See an example here: https://github.com/fchollet/keras/blob/master/examples/kaggle_otto_nn.py

public String formatStr(float val) {
 return String.format(Locale.CANADA, "%,.2f", val);
}

formatStr(2524.2) // 2,254.20

Use Regular expression to validate it.

isDate('2018-08-01T18:30:00.000Z');

isDate(_date){
        const _regExp  = new RegExp('^(-?(?:[1-9][0-9]*)?[0-9]{4})-(1[0-2]|0[1-9])-(3[01]|0[1-9]|[12][0-9])T(2[0-3]|[01][0-9]):([0-5][0-9]):([0-5][0-9])(.[0-9]+)?(Z)?$');

Since nobody posted the modern C++ approach yet,

#include <iostream>
#include <random>
int main()
{
    std::random_device rd; // obtain a random number from hardware
    std::mt19937 gen(rd()); // seed the generator
    std::uniform_int_distribution<> distr(25, 63); // define the range

    for(int n=0; n<40; ++n)
        std::cout << distr(gen) << ' '; // generate numbers
}

All of the current answers are wrong in some cases as they do not consider that timezones change their offset relative to UTC. So in some cases adding 24h is different from adding a calendar day.

tl;dr

• class C defines a class, just as in Java or C++.
• object O creates a singleton object O as instance of some anonymous class; it can be used to hold static members that are not associated with instances of some class.
• object O extends T makes the object O an instance of trait T; you can then pass O anywhere, a T is expected.
• if there is a class C, then object C is the companion object of class C; note that the companion object is not automatically an instance of C.

Also see Scala documentation for object and class.

object as host of static members

Most often, you need an object to hold methods and values/variables that shall be available without having to first instantiate an instance of some class. This use is closely related to static members in Java.

object A {
  def twice(i: Int): Int = 2*i
}

You can then call above method using A.twice(2).

If twice were a member of some class A, then you would need to make an instance first:

class A() {
  def twice(i: Int): Int = 2 * i
}

val a = new A()
a.twice(2)

You can see how redundant this is, as twice does not require any instance-specific data.

object as a special named instance

You can also use the object itself as some special instance of a class or trait. When you do this, your object needs to extend some trait in order to become an instance of a subclass of it.

Consider the following code:

object A extends B with C {
  ...
}

This declaration first declares an anonymous (inaccessible) class that extends both B and C, and instantiates a single instance of this class named A.

This means A can be passed to functions expecting objects of type B or C, or B with C.

Additional Features of object

There also exist some special features of objects in Scala. I recommend to read the official documentation.

• def apply(...) enables the usual method name-less syntax of A(...)
• def unapply(...) allows to create custom pattern matching extractors
• if accompanying a class of the same name, the object assumes a special role when resolving implicit parameters

In addition to what Kiran's answer suggests, make sure this is set correctly:

There is an option to in SSIS to save passwords(to access DB or anyother stuff), the default setting is "EncryptSensitiveWithUserKey"... You need to change this.

Package Proprties Window > ProtectionLevel -- Change that to EncryptSensitiveWithPassword PackagePassword -- enter password-> somepassword

I found I can make the match when I input a hard-coded non-breaking space (U+00A0) by typing Alt+0160 on Windows between the two quotes...

//table[@id='TableID']//td[text()=' ']

worked for me with the special char.

From what I understood, the XPath 1.0 standard doesn't handle escaping Unicode chars. There seems to be functions for that in XPath 2.0 but it looks like Firefox doesn't support it (or I misunderstood something). So you have to do with local codepage. Ugly, I know.

Actually, it looks like the standard is relying on the programming language using XPath to provide the correct Unicode escape sequence... So, somehow, I did the right thing.

Add display: block;. That's the difference between a <div> tag and an <a> tag

.btn {
      display: block;
      height: 300px;
      width: 300px;
      border-radius: 50%;
      border: 1px solid red;
    }

In my case, the icon of the app was causing the error:

<application
    android:name="com.test.MyApp"
    android:icon="@drawable/myicon"

Why? Because I put the icon only in the folder "drawable", and I'm using a high resolution testing device, so it looks in the folder "drawable-hdpi" for the icon. The default behaviour for everything else is use the icons from "drawable" if they aren't in "drawable-hdpi". But for the launching icon this doesn't seem to be valid.

So the solution is to put a copy of the icon (with the same name, of course) in "drawable-hdpi" (or whichever supported resolutions the devices have).

I deleted the file /public_html/bootstrap/cache/config.php

then I ran php artisan config:cache

This worked for me

Building on the other answers I've written this helper that accomplishes the task, including example usage:

public static class Helper
{
    public static List<T> RawSqlQuery<T>(string query, Func<DbDataReader, T> map)
    {
        using (var context = new DbContext())
        {
            using (var command = context.Database.GetDbConnection().CreateCommand())
            {
                command.CommandText = query;
                command.CommandType = CommandType.Text;

                context.Database.OpenConnection();

                using (var result = command.ExecuteReader())
                {
                    var entities = new List<T>();

                    while (result.Read())
                    {
                        entities.Add(map(result));
                    }

                    return entities;
                }
            }
        }
    }

Usage:

public class TopUser
{
    public string Name { get; set; }

    public int Count { get; set; }
}

var result = Helper.RawSqlQuery(
    "SELECT TOP 10 Name, COUNT(*) FROM Users U"
    + " INNER JOIN Signups S ON U.UserId = S.UserId"
    + " GROUP BY U.Name ORDER BY COUNT(*) DESC",
    x => new TopUser { Name = (string)x[0], Count = (int)x[1] });

result.ForEach(x => Console.WriteLine($"{x.Name,-25}{x.Count}"));

I plan to get rid of it as soon as built-in support is added. According to a statement by Arthur Vickers from the EF Core team it is a high priority for post 2.0. The issue is being tracked here.

select *
from {Table_Name}
where {x_column_name}=(
    select d.{x_column_name} 
    from (
        select rownum as rno,{x_column_name}
        from {Table_Name})d
        where d.rno=(
            select count(*)
            from {Table_Name}));

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

You want to use the atof() function.
