Programs & Examples On #Postdata

<html:form name="Form" type="abc" action="abc.do" method="get" onsubmit="return false;">

method="get" - resolves the problem.

if method="post" then only warning comes.

If we use a template-light-solution (as shown above) like the following:

namespace std {
    template<typename T>
    std::string to_string(const T &n) {
        std::ostringstream s;
        s << n;
        return s.str();
    }
}

Unfortunately, we will have problems in some cases. For example, for static const members:

hpp

class A
{
public:

    static const std::size_t x = 10;

    A();
};

cpp

A::A()
{
    std::cout << std::to_string(x);
}

And linking:

CMakeFiles/untitled2.dir/a.cpp.o:a.cpp:(.rdata$.refptr._ZN1A1xE[.refptr._ZN1A1xE]+0x0): undefined reference to `A::x'
collect2: error: ld returned 1 exit status

Here is one way to solve the problem (add to the type size_t):

namespace std {
    std::string to_string(size_t n) {
        std::ostringstream s;
        s << n;
        return s.str();
    }
}

HTH.

@user20877984's answer is excellent. Since they summed it up far better than my previous answer, here is my (posibly still shoddy) attempt at an application of the concept:

Using do.call in a basic fashion:

powvalues <- list(power=0.9,delta=2)
do.call(power.t.test,powvalues)

Working on a full data set:

# get the example data
df <- data.frame(delta=c(1,1,2,2), power=c(.90,.85,.75,.45))

#> df
#  delta power
#1     1  0.90
#2     1  0.85
#3     2  0.75
#4     2  0.45

lapply the power.t.test function to each of the rows of specified values:

result <- lapply(
  split(df,1:nrow(df)),
  function(x) do.call(power.t.test,x)
)

> str(result)
List of 4
 $ 1:List of 8
  ..$ n          : num 22
  ..$ delta      : num 1
  ..$ sd         : num 1
  ..$ sig.level  : num 0.05
  ..$ power      : num 0.9
  ..$ alternative: chr "two.sided"
  ..$ note       : chr "n is number in *each* group"
  ..$ method     : chr "Two-sample t test power calculation"
  ..- attr(*, "class")= chr "power.htest"
 $ 2:List of 8
  ..$ n          : num 19
  ..$ delta      : num 1
  ..$ sd         : num 1

Yes, its possible to have array of objects in PHP.

class MyObject {
  private $property;

  public function  __construct($property) {
    $this->Property = $property;
  }
}
$ListOfObjects[] = new myObject(1); 
$ListOfObjects[] = new myObject(2); 
$ListOfObjects[] = new myObject(3); 
$ListOfObjects[] = new myObject(4); 

print "<pre>";
print_r($ListOfObjects);
print "</pre>";

Minor change in iTunes Connect,

• Login to iTunes Connect
• Select your app from My Apps section
• Select App Store tab, Then select Pricing & Availability section
• Under Availability section you will see two options 1) Available in all territories 2) Remove from sale, Kindly refer below screenshot for the same.
• Select remove from sale if you would like to remove from all territories, if you would like to remove from specific territory then click on edit & remove from selected territory.

There is no cross browser way of doing it, for security reasons. What people usually do is overlay the input file over something else and set it's visibility to hidden so it gets triggered on it's own. More info here.

To Use Jquery in Angular2(4)

Follow these setps

install the Jquery and Juqry type defination

For Jquery Installation npm install jquery --save

For Jquery Type defination Installation npm install @types/jquery --save-dev

and then simply import the jquery

import { Component } from '@angular/core';
import * as $ from 'jquery';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent { 
  console.log($(window)); // jquery is accessible 
}

(Update: overlooked a fault in the matter, I have corrected)

There is an open issue to only print this warning if there was actually something sanitized: https://github.com/angular/angular/pull/10272

I didn't read in detail when this warning is printed when nothing was sanitized.

Now docker-compose supports variable substitution.

Compose uses the variable values from the shell environment in which docker-compose is run. For example, suppose the shell contains POSTGRES_VERSION=9.3 and you supply this configuration in your docker-compose.yml file:

db:
  image: "postgres:${POSTGRES_VERSION}"

When you run docker-compose up with this configuration, Compose looks for the POSTGRES_VERSION environment variable in the shell and substitutes its value in. For this example, Compose resolves the image to postgres:9.3 before running the configuration.

You need to tell Angular that your directive uses a scope variable:

You need to bind some property of the scope to your directive:

return {
    restrict: 'E',
    scope: {
      whatever: '='
    },
   ...
}

and then $watch it:

  $scope.$watch('whatever', function(value) {
    // do something with the new value
  });

Refer to the Angular documentation on directives for more information.

In my case, onRestoreInstanceState was called when the activity was reconstructed after changing the device orientation. onCreate(Bundle) was called first, but the bundle didn't have the key/values I set with onSaveInstanceState(Bundle).

Right after, onRestoreInstanceState(Bundle) was called with a bundle that had the correct key/values.

The main difference between struts & spring MVC is about the difference between Aspect Oriented Programming (AOP) & Object oriented programming (OOP).

Spring makes application loosely coupled by using Dependency Injection.The core of the Spring Framework is the IoC container.

OOP can do everything that AOP does but different approach. In other word, AOP complements OOP by providing another way of thinking about program structure.

Practically, when you want to apply same changes for many files. It should be exhausted work with Struts to add same code for tons of files. Instead Spring write new changes somewhere else and inject to the files.

Some related terminologies of AOP is cross-cutting concerns, Aspect, Dependency Injection...

Copy-paste snippet:

    """Return a class instance from a string reference"""
    try:
        module_ = importlib.import_module(module_name)
        try:
            class_ = getattr(module_, class_name)()
        except AttributeError:
            logging.error('Class does not exist')
    except ImportError:

let delta = Math.floor(Math.abs(start.getTime() - end.getTime()) / 1000);
let hours = Math.floor(delta / 3600);
delta -= hours * 3600;
let minutes = Math.floor(delta / 60);
delta -= minutes * 60;
let seconds = delta;
if (hours.toString().length === 1) {
  hours = `0${hours}`;
}
if (minutes.toString().length === 1) {
  minutes = `0${minutes}`;
}
if (seconds.toString().length === 1) {
  seconds = `0${seconds}`;
}
const recordingTime = `${hours}:${minutes}:${seconds}`;

This is a possible implementation of the required Bash function:

# Print the newest file, if any, matching the given pattern
# Example usage:
#   newest_matching_file 'b2*'
# WARNING: Files whose names begin with a dot will not be checked
function newest_matching_file
{
    # Use ${1-} instead of $1 in case 'nounset' is set
    local -r glob_pattern=${1-}

    if (( $# != 1 )) ; then
        echo 'usage: newest_matching_file GLOB_PATTERN' >&2
        return 1
    fi

    # To avoid printing garbage if no files match the pattern, set
    # 'nullglob' if necessary
    local -i need_to_unset_nullglob=0
    if [[ ":$BASHOPTS:" != *:nullglob:* ]] ; then
        shopt -s nullglob
        need_to_unset_nullglob=1
    fi

    newest_file=
    for file in $glob_pattern ; do
        [[ -z $newest_file || $file -nt $newest_file ]] \
            && newest_file=$file
    done

    # To avoid unexpected behaviour elsewhere, unset nullglob if it was
    # set by this function
    (( need_to_unset_nullglob )) && shopt -u nullglob

    # Use printf instead of echo in case the file name begins with '-'
    [[ -n $newest_file ]] && printf '%s\n' "$newest_file"

    return 0
}

It uses only Bash builtins, and should handle files whose names contain newlines or other unusual characters.

Running chrome.exe --start-fullscreen --app=https://google.com will not get you Chrome in fullscreen, but in kiosk mode.

However, running chrome --start-fullscreen --app=https://google.com (notice : it's chrome instead of chrome.exe) worked in my case.

The input operator for number skips leading whitespace, so you can just read the number in a loop:

while (myfile >> a)
{
    // ...
}

First step would be making the function object, then applying it. If you want a matrix object that has the same number of rows, you can predefine it and use the object[] form as illustrated (otherwise the returned value will be simplified to a vector):

bvnormdens <- function(x=c(0,0),mu=c(0,0), sigma=c(1,1), rho=0){
     exp(-1/(2*(1-rho^2))*(x[1]^2/sigma[1]^2+
                           x[2]^2/sigma[2]^2-
                           2*rho*x[1]*x[2]/(sigma[1]*sigma[2]))) * 
     1/(2*pi*sigma[1]*sigma[2]*sqrt(1-rho^2))
     }
 out=rbind(c(1,2),c(3,4),c(5,6));

 bvout<-matrix(NA, ncol=1, nrow=3)
 bvout[] <-apply(out, 1, bvnormdens)
 bvout
             [,1]
[1,] 1.306423e-02
[2,] 5.931153e-07
[3,] 9.033134e-15

If you wanted to use other than your default parameters then the call should include named arguments after the function:

bvout[] <-apply(out, 1, FUN=bvnormdens, mu=c(-1,1), rho=0.6)

apply() can also be used on higher dimensional arrays and the MARGIN argument can be a vector as well as a single integer.

Try something like this:

SELECT 
* 
FROM
(SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks) t1 
INNER JOIN
(SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks) t2
ON t1.ks = t2.ks

you can make a shell script with those commands, and then chmod +x <scriptname.sh>, and then just run it by

./scriptname.sh

Its very simple to write a bash script

Mockup sh file:

#!/bin/sh
sudo command1
sudo command2 
.
.
.
sudo commandn

Script for loading of custom .env file: Add the following lines to /config/environment.rb, between the require line, and the Application.initialize line:

# Load the app's custom environment variables here, so that they are loaded before environments/*.rb

app_environment_variables = File.join(Rails.root, 'config', 'local_environment.env')
if File.exists?(app_environment_variables)
  lines = File.readlines(app_environment_variables)
  lines.each do |line|
    line.chomp!
    next if line.empty? or line[0] == '#'
    parts = line.partition '='
    raise "Wrong line: #{line} in #{app_environment_variables}" if parts.last.empty?
    ENV[parts.first] = parts.last
  end
end

And config/local_environment.env (you will want to .gitignore it) will look like:

# This is ignored comment
DATABASE_URL=mysql2://user:[email protected]:3307/database
RACK_ENV=development

I find the following code to be much simpler than anything else:

function setCookie(name,value,days) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days*24*60*60*1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}
function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}
function eraseCookie(name) {   
    document.cookie = name +'=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;';
}

Now, calling functions

setCookie('ppkcookie','testcookie',7);

var x = getCookie('ppkcookie');
if (x) {
    [do something with x]
}

This answer is similar to Dmitry, but it will allow for decimals as well as positive and negative numbers.

select * from table where col1 REGEXP '^[[:digit:]]+$'

You can do:

\bjack\b.*\bjames\b|\bjames\b.*\bjack\b

long strtol (const char *String, char **EndPointer, int Base)

// examples
strtol(s, NULL, 10);

Here it is in one line, without having to retype any of the variables or their values:

fruitdict.update({k:v for k,v in locals().copy().iteritems() if k[:2] != '__' and k != 'fruitdict'})

• Download the svn binaries
• unpack them somewhere and add the bin folder to your PATH environment variable
• open a command line console (cmd.exe)
• enter than "svn checkout ...." command there
  • make sure to first cd to the place where you want to download (i.e checkout) the projects' code.

You can do this without additional tools in VBScript:

Do Until WScript.StdIn.AtEndOfStream
  WScript.StdOut.WriteLine WScript.StdIn.ReadLine
Loop

Put the above lines in a file unix2dos.vbs and run it like this:

cscript //NoLogo unix2dos.vbs <C:\path\to\input.txt >C:\path\to\output.txt

or like this:

type C:\path\to\input.txt | cscript //NoLogo unix2dos.vbs >C:\path\to\output.txt

You can also do it in PowerShell:

(Get-Content "C:\path\to\input.txt") -replace "`n", "`r`n" |
  Set-Content "C:\path\to\output.txt"

which could be further simplified to this:

(Get-Content "C:\path\to\input.txt") | Set-Content "C:\path\to\output.txt"

The above statement works without an explicit replacement, because Get-Content implicitly splits input files at any kind of linebreak (CR, LF, and CR-LF), and Set-Content joins the input array with Windows linebreaks (CR-LF) before writing it to a file.

The simplest make file can be

all : test

test : test.o
        gcc -o test test.o 

test.o : test.c
        gcc -c test.c

clean :
        rm test *.o

After finding all solutions for this small issue for macOS only.
Finally, I got my TSC works on my MacBook pro.

This might be the best solution I found out.

For all macOS users, instead of installing TypeScript using NPM, you can install TypeScript using homebrew.

brew install typescript

Please see attached screencap for reference.

I would say it's more a problem of the way you're modeling your data. Instead of using string arrays for addresses, it would be much cleaner and easier to do something like this:

Create a class to represent your addresses, like this:

public class Address
{
    public string Address1 { get; set; }
    public string CityName { get; set; }
    public string StateCode { get; set; }
    public string ZipCode { get; set; }
}

Then in your view model, you can populate those addresses like this:

public class ViewModel
{
    public IList<Address> Addresses = new List<Address>();

    public void PopulateAddresses()
    {
        foreach(DataRow row in AddressTable.Rows)
        {
            Address address = new Address
                {
                    Address1 = row["Address1"].ToString(),
                    CityName = row["CityName"].ToString(),
                    StateCode = row["StateCode"].ToString(),
                    ZipCode = row["ZipCode"].ToString()
                };
            Addresses.Add(address);
        }

        lAddressGeocodeModel.Addresses = JsonConvert.SerializeObject(Addresses);
    }
}

Which will give you JSON that looks like this:

[{"Address1" : "123 Easy Street", "CityName": "New York", "StateCode": "NY", "ZipCode": "12345"}]

Here are some helper functions I use:

Array.contains = function (arr, key) {
    for (var i = arr.length; i--;) {
        if (arr[i] === key) return true;
    }
    return false;
};

Array.add = function (arr, key, value) {
    for (var i = arr.length; i--;) {
        if (arr[i] === key) return arr[key] = value;
    }
    this.push(key);
};

Array.remove = function (arr, key) {
    for (var i = arr.length; i--;) {
        if (arr[i] === key) return arr.splice(i, 1);
    }
};

In addition to what provided in the other answers, the keyword "zorder" allows one to decide the order in which different objects are plotted vertically. E.g.:

plt.plot(x,y,zorder=1) 
plt.scatter(x,y,zorder=2)

plots the scatter symbols on top of the line, while

plt.plot(x,y,zorder=2)
plt.scatter(x,y,zorder=1)

plots the line over the scatter symbols.

See, e.g., the zorder demo

Get content with Curl php

request server support Curl function, enable in httpd.conf in folder Apache

function UrlOpener($url)
     global $output;
     $ch = curl_init(); 
     curl_setopt($ch, CURLOPT_URL, $url); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
     $output = curl_exec($ch); 
     curl_close($ch);    
     echo $output;

If get content by google cache use Curl you can use this url: http://webcache.googleusercontent.com/search?q=cache:Put your url Sample: http://urlopener.mixaz.net/

For a simple file search you could use grep's -l and -r options:

grep -rl "mystring"

All the search is done by grep. Of course, if you need to select files on some other parameter, find is the correct solution:

find . -iname "*.php" -execdir grep -l "mystring" {} +

The execdir option builds each grep command per each directory, and concatenates filenames into only one command (+).

There is another way to pass arguments to CreateInstance through named parameters.

Based on that, you can pass a array towards CreateInstance. This will allow you to have 0 or multiple arguments.

public T CreateInstance<T>(params object[] paramArray)
{
  return (T)Activator.CreateInstance(typeof(T), args:paramArray);
}

Generic toString() one-liner, using reflection and style customization:

import org.apache.commons.lang3.builder.ReflectionToStringBuilder;
import org.apache.commons.lang3.builder.ToStringStyle;
...
public String toString()
{
  return ReflectionToStringBuilder.toString(this, ToStringStyle.SHORT_PREFIX_STYLE);
}

This is something I need all the time so I created a bash function for it. It's based on glenn jackman's answer.

Definition

Add this to your .bash_profile etc.

function regex { gawk 'match($0,/'$1'/, ary) {print ary['${2:-'0'}']}'; }

Usage

Capture regex for each line in file

$ cat filename | regex '.*'

Capture 1st regex capture group for each line in file

$ cat filename | regex '(.*)' 1

Judging from the messages you send via Socket.IO socket.emit('greet', { hello: 'Hey, Mr.Client!' });, it seems that you are using the hackathon-starter boilerplate. If so, the issue might be that express-status-monitor module is creating its own socket.io instance, as per: https://github.com/RafalWilinski/express-status-monitor#using-module-with-socketio-in-project

You can either:

1. Remove that module

2. Pass in your socket.io instance and port as websocket when you create the expressStatusMonitor instance like below:

   const server = require('http').Server(app);
   const io = require('socket.io')(server);
   ...
   app.use(expressStatusMonitor({ websocket: io, port: app.get('port') }));

Some frameworks are using this header to detect xhr requests e.g. grails spring security is using this header to identify xhr request and give either a json response or html response as response.

Most Ajax libraries (Prototype, JQuery, and Dojo as of v2.1) include an X-Requested-With header that indicates that the request was made by XMLHttpRequest instead of being triggered by clicking a regular hyperlink or form submit button.

Source: http://grails-plugins.github.io/grails-spring-security-core/guide/helperClasses.html

I just use gulp-angular-filesort

function concatOrder() {

    return gulp.src('./build/src/app/**/*.js')
        .pipe(sort())
        .pipe(plug.concat('concat.js'))
        .pipe(gulp.dest('./output/'));
}

If you have Java 7 so include the below following snippet within your app-level build.gradle :

compileOptions {

    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7

}

The simplest way to do it is by using a pseudo-element like :before or :after.
This method will not require any additional html elements or jquery.
If we have for instance this html structure:

<div class="map_wraper">

    <iframe src="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d405689.7826944034!2d-122.04109805!3d37.40280355!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x808fb68ad0cfc739%3A0x7eb356b66bd4b50e!2sSilicon+Valley%2C+CA!5e0!3m2!1sen!2sro!4v1438864791455" width="600" height="450" frameborder="0" style="border:0" allowfullscreen></iframe>

</div>

Then all we need to do is make the wrapper relative to the pseudo-element we will create to prevent the scrolling

.map_wraper{
    position:relative;
}

After this we will create the pseudo-element that will be positioned over the map therefor preventing the scrolling:

.map_wraper:after{
    background: none;
    content: " ";
    display: inline-block;
    font-size: 0;
    height: 100%;
    left: 0;
    opacity: 0;
    position: absolute;
    top: 0;
    width: 100%;
    z-index: 9;
}

And you're done, no jquery no extra html elements! Here is a working jsfiddle example: http://jsfiddle.net/e6j4Lbe1/

If you use sufficiently big list not in b clause will do a linear search for each of the item in a. Why not use set? Set takes iterable as parameter to create a new set object.

>>> a = ["a", "b", "c", "d", "e"]
>>> b = ["c", "d", "f", "g"]
>>> set(a).intersection(set(b))
{'c', 'd'}

I tried using it and didn't work, guess it's just the modal versioin.

Although, it worked as this:

$("#myModal").on("hide.bs.modal", function () {
    // put your default event here
});

Just to update the answer =)

I have been composing my Jersey 1.17 services the following way:

FileStreamingOutput

public class FileStreamingOutput implements StreamingOutput {

    private File file;

    public FileStreamingOutput(File file) {
        this.file = file;
    }

    @Override
    public void write(OutputStream output)
            throws IOException, WebApplicationException {
        FileInputStream input = new FileInputStream(file);
        try {
            int bytes;
            while ((bytes = input.read()) != -1) {
                output.write(bytes);
            }
        } catch (Exception e) {
            throw new WebApplicationException(e);
        } finally {
            if (output != null) output.close();
            if (input != null) input.close();
        }
    }

}

GET

@GET
@Produces("application/pdf")
public StreamingOutput getPdf(@QueryParam(value="name") String pdfFileName) {
    if (pdfFileName == null)
        throw new WebApplicationException(Response.Status.BAD_REQUEST);
    if (!pdfFileName.endsWith(".pdf")) pdfFileName = pdfFileName + ".pdf";

    File pdf = new File(Settings.basePath, pdfFileName);
    if (!pdf.exists())
        throw new WebApplicationException(Response.Status.NOT_FOUND);

    return new FileStreamingOutput(pdf);
}

And the client, if you need it:

Client

private WebResource resource;

public InputStream getPDFStream(String filename) throws IOException {
    ClientResponse response = resource.path("pdf").queryParam("name", filename)
        .type("application/pdf").get(ClientResponse.class);
    return response.getEntityInputStream();
}

You want multiple lines of text indented on the left. Try the following:

CSS:

div.info {
    margin-left: 10px;
}

span.info {
    color: #b1b1b1;
    font-size: 11px;
    font-style: italic;
    font-weight:bold;
}

HTML:

<div class="info"><span class="info">blah blah <br/> blah blah</span></div>

Even though its not directly related. But I found that the CALC code won't work if you do not put spaces properly.

So this did not work for me calc(#{$a}+7px)

But this worked calc(#{$a} + 7px)

Took me sometime to figure this out.

If you're willing to use jquery, there is a handy jquery plugin called "inc".

I use it often for website prototyping, where I just want to present the client with static HTML with no backend layer that can be quickly created/edited/improved/re-presented

http://johannburkard.de/blog/programming/javascript/inc-a-super-tiny-client-side-include-javascript-jquery-plugin.html

For example, things like the menu and footer need to be shown on every page, but you dont want to end up with a copy-and-paste-athon

You can include a page fragment as follows

<p class="inc:footer.htm"></p>

There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.

And then you can copy for example the file "test.txt" from a remote host to the local host

scp [email protected]:test.txt /local/dir

@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.

In UNIX, absolute paths must start with '/'.

Try:

SELECT * 
FROM table 
WHERE datetime > 
CONVERT(DATETIME, 
CONVERT(VARCHAR(20), 
CONVERT(DATETIME, '2010-07-20 03:21:52'), 120))

Or if your date is an actual datetime value:

DECLARE @date DATETIME
SET @date = GETDATE()
SELECT CONVERT(DATETIME, CONVERT(VARCHAR(20), @date, 120))

The conversion to style 120 cuts off the milliseconds...

1. Go to Server tab

2. Click on No servers are available. Click this link to create a new server.

3. Select Tomcat V8.0 from server type list:

4. Provide path of server:

5. Click Finish.

6. You will see server added:

7. Right click->Start

Now you can run your web applications on server.

function convertToRoman(num) {
  var roman = {
    M: 1000,
    CM: 900,
    D: 500,
    CD: 400,
    C: 100,
    XC: 90,
    L: 50,
    XL: 40,
    X: 10,
    IX: 9,
    V: 5,
    IV: 4,
    I: 1
  }
  var result = '';
  for (var key in roman) {
    if (num == roman[key]) {
      return result +=key;
    }
    var check = num > roman[key];
    if(check) {
      result = result + key.repeat(parseInt(num/roman[key]));
      num = num%roman[key];
    }
  }
 return result;
}

console.log(convertToRoman(36));

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

This will get you a string array of all the resources:

System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();

This should work:

$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`

$data = DB::table('borrowers')
        ->join('loans', 'borrowers.id', '=', 'loans.borrower_id')
        ->select('borrowers.*', 'loans.*')   
        ->where('loan_officers', 'like', '%' . $officerId . '%')
        ->where('loans.maturity_date', '<', date("Y-m-d"))
        ->get();

A loop like this one:

else if (!(Character.isLowerCase(ch)))
            {
                for (int i=1; i<password.length(); i++)
                {
                   ch = password.charAt(i);

                    if (!Character.isLowerCase(ch))
                       {  
                        System.out.println("Invalid password - Must have a Lower Case character.");
                        password = "";
                       }
                     // end if
                } //end for
            }

Has an obvious logical flaw: You enter it if the first character is not lowercase, then test if the second character is not lower case. At that point you throw an error.

Instead, you should do something like this (not full code, just an example):

boolean hasLower = false, hasUpper = false, hasNumber = false, hasSpecial = false; // etc - all the rules
for ( ii = 0; ii < password.length(); ii++ ) {
  ch = password.charAt(ii);
  // check each rule in turn, with code like this:
  if Character.isLowerCase(ch) hasLower = true;
  if Character.isUpperCase(ch) hasUpper = true;
  // ... etc for all the tests you want to do
}

if(hasLower && hasUpper && ...) {
  // password is good
} 
else {
  // password is bad
}

Of course the code snippet you provided, besides the faulty logic, did not have code to test for the other conditions that your "help" option printed out. As was pointed out in one of the other answers, you could consider using regular expressions to help you speed up the process of finding each of these things. For example,

hasNumber  : use regex pattern "\d+" for "find at least one digit"
hasSpecial : use regex pattern "[!@#$%^&*]+" for "find at least one of these characters"

In code:

hasNumber  = password.matches(".*\\d.*");  // "a digit with anything before or after"
hasSpecial = password.matches(".*[!@#$%^&*].*");
hasNoNOT   = !password.matches(".*NOT.*");
hasNoAND   = !password.matches(".*AND.*");

It is possible to combine these things in clever ways - but especially when you are a novice regex user, it is much better to be a little bit "slow and tedious", and get code that works first time (plus you will be able to figure out what you did six months from now).

Look here for details.

private PerformanceCounter cpuCounter;
private PerformanceCounter ramCounter;
public Form1()
{
    InitializeComponent();
    InitialiseCPUCounter();
    InitializeRAMCounter();
    updateTimer.Start();
}

private void updateTimer_Tick(object sender, EventArgs e)
{
    this.textBox1.Text = "CPU Usage: " +
    Convert.ToInt32(cpuCounter.NextValue()).ToString() +
    "%";

    this.textBox2.Text = Convert.ToInt32(ramCounter.NextValue()).ToString()+"Mb";
}

private void Form1_Load(object sender, EventArgs e)
{
}

private void InitialiseCPUCounter()
{
    cpuCounter = new PerformanceCounter(
    "Processor",
    "% Processor Time",
    "_Total",
    true
    );
}

private void InitializeRAMCounter()
{
    ramCounter = new PerformanceCounter("Memory", "Available MBytes", true);

}

If you get value as 0 it need to call NextValue() twice. Then it gives the actual value of CPU usage. See more details here.

I've tried all of proposed solutions, but nothing worked for me while all my markers were under a cluster. Eventually I just put this:

var markerCluster = new MarkerClusterer(map, markers,
    { imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m' });
agentsGpsData[agentGpsData.ID].CLUSTER = markerCluster;

//this did the trick
agentsGpsData[agentId].CLUSTER.clearMarkers();

In other words, if you wrap markers in a cluster and want to remove all markers, you call:

clearMarkers();

FYI: A useful simulation tool - phpMyAdmin with Wampserver 3.0.6 - Preview SQL: I use 'Preview SQL' to see the SQL code that would be generated before you save the column with the change to ENUM. Preview SQL

Above you see that I have entered 'Ford','Toyota' into the ENUM but I am getting syntax ENUM(0) which is generating syntax error Query error 1064#

I then copy and paste and alter the SQL and run it through SQL with a positive result.

SQL changed

This is a quickfix that I use often and can also be used on existing ENUM values that need to be altered. Thought this might be useful.

If you don't want to write your own utility use Google's guava library:

Enums.getIfPresent(Blah.class, "A")

Unlike the built in java function it let's you check if A is present in Blah and doesn't throw an exception.

I use a very different approach to this. I set browser cookies in the client that expire a second after I set window.location.href.

This is way more secure than embedding your parameters in the URL.

The server receives the parameters as cookies, and the browser deletes the cookies right after they are sent.

const expires = new Date(Date.now() + 1000).toUTCString()
document.cookie = `oauth-username=user123; expires=${expires}`
window.location.href = `https:foo.com/oauth/google/link`

To each his own but the right way to code this is to rename the columns inserting underscore so there are no gaps. This will ensure zero errors when coding. When printing the column names for public display you could search-and-replace to replace the underscore with a space.

(Taken from my comment)

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)

There's a fantastic jQuery tutorial for this at https://web.archive.org/web/20121012171851/http://jqueryfordesigners.com/fixed-floating-elements/.

It replicates the Apple.com shopping cart type of sidebar scrolling. The Google query that might have served you well is "fixed floating sidebar".

I was working with talend V7.3.1 and I had poi version "4.1.0" and including xml-beans from the list of dependencies didnt fix my problem (i.e: 2.3.0 and 2.6.0).

It was fixed by downloading the jar "xmlbeans-3.0.1.jar" and adding it to the project

Assuming you have two Date objects, you can just subtract them to get the difference in milliseconds:

var difference = date2 - date1;

From there, you can use simple arithmetic to derive the other values.

For the record, my system is Ubuntu Server 20.04 and none of the solutions here worked. For me, I installed PHP 7.4 and I had to edit enter code here/etc/php/7.4/apache2/php.ini`.

Within this, search for ;extension=mysqli, uncomment and change mysqli to mysqlnd so it should look like this extension=mysqlnd. I tried using mysqli but I faced the same error as if I didn't enable it but mysqlnd worked for me.

I wrote a very tiny plugin called "once" which do that. Execute off and on in element.

$.fn.once = function(a, b) {
    return this.each(function() {
        $(this).off(a).on(a,b);
    });
};

And simply:

$(element).once('click', function(){
});

Export all the needed variables and then use a perl onliner

TEXT=$(echo "$TEXT"|perl -wpne 's#\${?(\w+)}?# $ENV{$1} // $& #ge;')

This will replace all the ENV variables present in TEXT with actual values. Quotes are also preserved :)

try

el.css('margin-left',mrg+'px');

x ~= 0 or 1 is the same as ((x ~= 0) or 1)

x ~=(0 or 1) is the same as (x ~= 0).

try something like this instead.

function isNot0Or1(x)
    return (x ~= 0 and x ~= 1)
end

print( isNot0Or1(-1) == true )
print( isNot0Or1(0) == false )
print( isNot0Or1(1) == false )

Should be:

       (SELECT CASE
        WHEN COUNT(*)< 2 THEN 'Ama'
        WHEN COUNT(*)< 5 THEN 'SemiAma' 
        WHEN COUNT(*)< 7 THEN 'Good'  
        WHEN COUNT(*)< 9 THEN 'Better' 
        WHEN COUNT(*)< 12 THEN 'Best'
        ELSE 'Outstanding'
        END as a FROM Articles 
        WHERE Articles.userId = Users.userId) as ranking,
        (SELECT COUNT(*) 
        FROM Articles 
        WHERE userId = Users.userId) as articleNumber,
hobbies, etc...

That's a difficult problem to solve since visually similar PDFs may have a wildly differing structure depending on how they were produced. In the worst case the library would need to basically act like an OCR. On the other hand, the PDF may contain sufficient structure and metadata for easy removal of tables and figures, which the library can be tailored to take advantage of.

I'm pretty sure there are no open source tools which solve your problem for a wide variety of PDFs, but I remember having heard of commercial software claiming to do exactly what you ask for. I'm sure you'll run into them while googling.

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

Inspired by Radek and Spencer... On Rails 4(.0.2 - Ruby 2.1.0 ), I was able to append this to config/boot.rb:

# config/boot.rb

# ...existing code

require 'rails/commands/server'

module Rails
  # Override default development
  # Server port
  class Server
    def default_options
      super.merge(Port: 3100)
    end
  end
end

All other configuration in default_options are still set, and command-line switches still override defaults.

Maybe

df <- do.call("cbind", list(df, rep(list(NA),length(namevector))))
colnames(df)[-1*(1:(ncol(df) - length(namevector)))] <- namevector

Windows:

<workspace>\.metadata\.plugins\org.eclipse.core.resources\.projects\

Linux / osx:

<workspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/

Your project can exist outside the workspace, but all Eclipse-specific metadata are stored in that org.eclipse.core.resources\.projects directory

I think you could do something like this:

var $child = $("#parentId").append("<div></div>").children("div:last-child");

The parent #parentId is returned from the append, so add a jquery children query to it to get the last div child inserted.

$child is then the jquery wrapped child div that was added.

I removed your document.getElementById("Save").onclick = before your functions, because it's an event already being called on your button. I also had to call the two functions separately by the onclick event.

     <!DOCTYPE html>
      <html>
      <head>
      <script>
       function fun()
        {
         alert("hello");
         //validation code to see State field is mandatory.  
        }   
        function f1()
        {
          alert("f1 called");
           //form validation that recalls the page showing with supplied inputs.    
        }
      </script>
      </head>
      <body>
      <form name="form1" id="form1" method="post">
                State: 
                <select id="state ID">
                   <option></option>
                   <option value="ap">ap</option>
                   <option value="bp">bp</option>
                </select>
       </form>

       <table><tr><td id="Save" onclick="f1(); fun();">click</td></tr></table>

   </body>
   </html>

try this one http://code.google.com/p/geckofx/ hope it ain't dupe or this one i think is better http://webkitdotnet.sourceforge.net/

You can accomplish this via method overloading.

public int doSomething(int arg1, int arg2)
{
        return 0;
}

public int doSomething()
{
        return doSomething(defaultValue0, defaultValue1);
}

By creating this parameterless method you are allowing the user to call the parameterfull method with the default arguments you supply within the implementation of the parameterless method. This is known as overloading the method.

-- If no parameters need to be passed to a procedure, simply:

BEGIN
   MY_PACKAGE_NAME.MY_PROCEDURE_NAME
END;

That's more specifically a ternary operator expression than an if-then, here's the python syntax

value_when_true if condition else value_when_false

Better Example: (thanks Mr. Burns)

'Yes' if fruit == 'Apple' else 'No'

Now with assignment and contrast with if syntax

fruit = 'Apple'
isApple = True if fruit == 'Apple' else False

vs

fruit = 'Apple'
isApple = False
if fruit == 'Apple' : isApple = True

'SET' is forgotten

you may use this query for selecting top records in oracle. Rakesh B

select * from User_info where id >= (select max(id)-10 from User_info);

In MySQL, <> means Not Equal To, just like !=.

mysql> SELECT '.01' <> '0.01';
        -> 1
mysql> SELECT .01 <> '0.01';
        -> 0
mysql> SELECT 'zapp' <> 'zappp';
        -> 1

In SQL, the order of the output is not defined unless you specify it in the ORDER BY clause.

Try this:

SELECT  *

ORDER BY
        one.id

use market://

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + my_packagename));

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

My take on this for future people watching this:

This could also happen if you're using: <? instead of <?php.

path = r"C:\Users\mememe\Google Drive\Programs\Python\file.csv"

Closing the path in r"string" also solved this problem very well.

Use QString::arg() for the same effect.

For anyone else having the issue - none of the answers provided worked for me.

My case may be different to others but I had Android Studio installed first which installs the SDK by default to: C:\Users\[user]\AppData\Local\Android\sdk. We then decided to use Xamarin for our projects, so Xamarin was installed and installed an additional SDK by default, located here: C:\Program Files (x86)\Android\android-sdk.

Changing Xamarin to match the same SDK path worked for me which I did in the registry (although through the VS settings I'd guess it's the same):

\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools\Path

Change the path to match the Android Studio SDK path, close everything, start the VS Emulator, run Android Studio, ensure ADB integration is off and try. It worked for me.

For Ubuntu: add extension=php_curl.so to php.ini to enable, if necessary. Then sudo service apache2 restart

this is generally taken care of automatically, but there are situations - eg, in shared development environments - where it can become necessary to re-enable manually.

The thumbprint will match all three of these conditions:

1. Fatal Error on curl_init() call
2. in php_info, you will see the curl module author (indicating curl is installed and available)
3. also in php_info, you will see no curl config block (indicating curl wasn't loaded)

we can enable CORS in the frontend by using the ngResourse module. But most importantly, we should have this piece of code while making the ajax request in the controller,

$scope.weatherAPI = $resource(YOUR API,
     {callback: "JSON_CALLBACK"}, {get: {method: 'JSONP'}});
 $scope.weatherResult = $scope.weatherAPI.get(YOUR REQUEST DATA, if any);

Also, you must add ngResourse CDN in the script part and add as a dependency in the app module.

<script src="https://code.angularjs.org/1.2.16/angular-resource.js"></script>

Then use "ngResourse" in the app module dependency section

var routerApp = angular.module("routerApp", ["ui.router", 'ngResource']);

This should do it (where df is your dataframe)

df$JoiningDate <- as.Date(df$JoiningDate , format = "%m/%d/%y")

df[order(df$JoiningDate ),]

var __startTime = moment("2016-06-06T09:00").format();
var __endTime = moment("2016-06-06T21:00").format();

var __duration = moment.duration(moment(__endTime).diff(__startTime));
var __hours = __duration.asHours();
console.log(__hours);

This is for dynamic # of weeks.

Full example here:SQL Dynamic Pivot

DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)

--Get distinct values of the PIVOT Column 
SELECT @ColumnName= ISNULL(@ColumnName + ',','') + QUOTENAME(Week)
FROM (SELECT DISTINCT Week FROM #StoreSales) AS Weeks

--Prepare the PIVOT query using the dynamic 
SET @DynamicPivotQuery = 
  N'SELECT Store, ' + @ColumnName + ' 
    FROM #StoreSales
    PIVOT(SUM(xCount) 
          FOR Week IN (' + @ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query
EXEC sp_executesql @DynamicPivotQuery

You can also use below code

$request->request->set(key, value).

Fits better for me.

$percentage = 50;
$totalWidth = 350;

$new_width = ($percentage / 100) * $totalWidth;

There are jQuery-plugins that help you achieve this like: http://ricostacruz.com/jquery.transit/

A lot of good solutions and valuable commentaries by known experts from JS community on the topic could be found here. It could be an indicator that it's not that trivial problem as it may seem. I think this is why it could be the source of doubts and uncertainty on the issue.

Fundamental problem here is that in React you're only allowed to mount component to its parent, which is not always the desired behavior. But how to address this issue?

I propose the solution, addressed to fix this issue. More detailed problem definition, src and examples can be found here: https://github.com/fckt/react-layer-stack#rationale

Rationale

react/react-dom comes comes with 2 basic assumptions/ideas:

• every UI is hierarchical naturally. This why we have the idea of components which wrap each other
• react-dom mounts (physically) child component to its parent DOM node by default

The problem is that sometimes the second property isn't what you want in your case. Sometimes you want to mount your component into different physical DOM node and hold logical connection between parent and child at the same time.

Canonical example is Tooltip-like component: at some point of development process you could find that you need to add some description for your UI element: it'll render in fixed layer and should know its coordinates (which are that UI element coord or mouse coords) and at the same time it needs information whether it needs to be shown right now or not, its content and some context from parent components. This example shows that sometimes logical hierarchy isn't match with the physical DOM hierarchy.

Take a look at https://github.com/fckt/react-layer-stack/blob/master/README.md#real-world-usage-example to see the concrete example which is answer to your question:

import { Layer, LayerContext } from 'react-layer-stack'
// ... for each `object` in array of `objects`
  const modalId = 'DeleteObjectConfirmation' + objects[rowIndex].id
  return (
    <Cell {...props}>
        // the layer definition. The content will show up in the LayerStackMountPoint when `show(modalId)` be fired in LayerContext
        <Layer use={[objects[rowIndex], rowIndex]} id={modalId}> {({
            hideMe, // alias for `hide(modalId)`
            index } // useful to know to set zIndex, for example
            , e) => // access to the arguments (click event data in this example)
          <Modal onClick={ hideMe } zIndex={(index + 1) * 1000}>
            <ConfirmationDialog
              title={ 'Delete' }
              message={ "You're about to delete to " + '"' + objects[rowIndex].name + '"' }
              confirmButton={ <Button type="primary">DELETE</Button> }
              onConfirm={ this.handleDeleteObject.bind(this, objects[rowIndex].name, hideMe) } // hide after confirmation
              close={ hideMe } />
          </Modal> }
        </Layer>

        // this is the toggle for Layer with `id === modalId` can be defined everywhere in the components tree
        <LayerContext id={ modalId }> {({showMe}) => // showMe is alias for `show(modalId)`
          <div style={styles.iconOverlay} onClick={ (e) => showMe(e) }> // additional arguments can be passed (like event)
            <Icon type="trash" />
          </div> }
        </LayerContext>
    </Cell>)
// ...

%date% will give you the date.

%time% will give you the time.

The date and time /t commands may give you more detail.

Try:

awk -F',' '{print $3}' myfile.txt

Here in -F you are saying to awk that use "," as field separator.

This is what I used to use a csv file into an array. Couldn't get the above answers to work, but this worked for me.

$(document).ready(function() {
   "use strict";
    $.ajax({
        type: "GET",
        url: "../files/icd10List.csv",
        dataType: "text",
        success: function(data) {processData(data);}
     });
});

function processData(icd10Codes) {
    "use strict";
    var input = $.csv.toArrays(icd10Codes);
    $("#test").append(input);
}

Used the jQuery-CSV Plug-in linked above.

No, instead you would need to do something like this depending on your needs:

function myFunction(myDate, myString) {
  if(arguments.length > 1 && typeof(Date.parse(myDate)) == "number" && typeof(myString) == "string") {
    //Code here
  }
}

Here's an example that will center the content within the parent div. This also makes sure the overlay starts at the edge of the video, even when centered.

<div class="outer-container">
    <div class="inner-container">
        <div class="video-overlay">Bug Buck Bunny - Trailer</div>
        <video id="player" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" controls autoplay loop></video>
    </div>
</div>

with css as

.outer-container {
    border: 1px dotted black;
    width: 100%;
    height: 100%;
    text-align: center;
}
.inner-container {
    border: 1px solid black;
    display: inline-block;
    position: relative;
}
.video-overlay {
    position: absolute;
    left: 0px;
    top: 0px;
    margin: 10px;
    padding: 5px 5px;
    font-size: 20px;
    font-family: Helvetica;
    color: #FFF;
    background-color: rgba(50, 50, 50, 0.3);
}
video {
    width: 100%;
    height: 100%;
}

here's the jsfiddle https://jsfiddle.net/dyrepk2x/2/

Hope that helps :)

It has nothing to do with jQuery, it's just a handy js method built into modern browsers.

Think of it as a handy alternative to debugging via window.alert()

As of OS X 10.10.1 (Yosemite), the location of the cacerts file has been changed to

$(/usr/libexec/java_home)/jre/lib/security/cacerts

Around 1:51 in the video, notice how she puts a <script> tag in there? The way it works is like this:

Create an html file (that's just a text file with a .html ending) somewhere on your computer. In the same folder that you put index.html, put a javascript file (that's just a textfile with a .js ending - let's call it game.js). Then, in your index.html file, put some html that includes the script tag with game.js, like Mary did in the video. index.html should look something like this:

<html>
    <head>
        <script src="game.js"></script>
    </head>
</html>

Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).

Good luck on your journey, hope it's as fun for you as it has been for me so far :)

My solution was to create a pipelined function. The advantages are that the query can be a single line:

• select * from table(yourfunction(param1, param2));
• You can join your results to other tables or filter or sort them as you please..
• the results appear as regular query results so you can easily manipulate them.

To define the function you would need to do something like the following:

  -- Declare the record columns
  TYPE your_record IS RECORD(
     my_col1 VARCHAR2(50), 
     my_col2 varchar2(4000)
  );
  TYPE your_results IS TABLE OF your_record;

  -- Declare the function
  function yourfunction(a_Param1 varchar2, a_Param2 varchar2)
  return your_results pipelined is
    rt          your_results;
  begin
    -- Your query to load the table type
    select s.col1,s.col2
    bulk collect into rt
    from your_table s
    where lower(s.col1) like lower('%'||a_Param1||'%');

    -- Stuff the results into the pipeline..
    if rt.count > 0 then 
      for i in rt.FIRST .. rt.LAST loop 
        pipe row (rt(i)); 
      end loop; 
    end if;

    -- Add more results as you please....
    return;
  end find;

And as mentioned above, all you would do to view your results is:

select * from table(yourfunction(param1, param2)) t order by t.my_col1;

Based on solution by Pavel Cerný here we can make an universal typed implementation of this pattern. To to it, we need to introduce NamedService interface:

    public interface NamedService {
       String name();
    }

and add abstract class:

public abstract class AbstractFactory<T extends NamedService> {

    private final Map<String, T> map;

    protected AbstractFactory(List<T> list) {
        this.map = list
                .stream()
                .collect(Collectors.toMap(NamedService::name, Function.identity()));
    }

    /**
     * Factory method for getting an appropriate implementation of a service
     * @param name name of service impl.
     * @return concrete service impl.

     */
    public T getInstance(@NonNull final String name) {
        T t = map.get(name);
        if(t == null)
            throw new RuntimeException("Unknown service name: " + name);
        return t;
    }
}

Then we create a concrete factory of specific objects like MyService:

 public interface MyService extends NamedService {
           String name();
           void doJob();
 }

@Component
public class MyServiceFactory extends AbstractFactory<MyService> {

    @Autowired
    protected MyServiceFactory(List<MyService> list) {
        super(list);
    }
}

where List the list of implementations of MyService interface at compile time.

This approach works fine if you have multiple similar factories across app that produce objects by name (if producing objects by a name suffice you business logic of course). Here map works good with String as a key, and holds all the existing implementations of your services.

if you have different logic for producing objects, this additional logic can be moved to some another place and work in combination with these factories (that get objects by name).

I might argue that the answer here generally is "don't". Unless you absolutely need all the data at once, consider using a Stream-based API (or some variant of reader / iterator). That is especially important when you have multiple parallel operations (as suggested by the question) to minimise system load and maximise throughput.

For example, if you are streaming data to a caller:

Stream dest = ...
using(Stream source = File.OpenRead(path)) {
    byte[] buffer = new byte[2048];
    int bytesRead;
    while((bytesRead = source.Read(buffer, 0, buffer.Length)) > 0) {
        dest.Write(buffer, 0, bytesRead);
    }
}

TCP is a connection oriented protocol, It establishes a path, or a virtual connection all the way through switches routers proxies etc and then starts any communication. Various mechanisms like routing djikstras shortest path algorithm exist to establish the virtual end to end connection. So it finds itself used while browsing HTML and other pages, making payments and web applications in general.

UDP is a connectionless protocol - it simply has a destination and nodes simply pass it along if it comes as best as they can. So packets arriving out of order, along various routes etc are common. So Instant messengers and similar software developers think UDP an ideal solution.

In real life if you want to throw data in the net, without worrying about time taken to reach, order of reaching use UDP. If you want a solid path before you start throwing packets, and want same order and latency for your data packets use TCP - I will use UDP for Torrents and TCP for PayPal!

Pretty late response but you can do the following in Kotlin:

activity?.applicationContext?.let { SymptomsAdapters(it, param2, param3, ...) }

(?.) is for safe null operation to prevent from the null pointer exception.

You do not want to create a new context as that can lead to memory leaks when interchanging between fragments or when the device changes rotation.

And as someone mentioned above, in Java you can obtain context in a fragment by doing the following:

getActivity().getApplicationContext()

You are using the wrong build.gradle file.

In your top-level file you can't define an android block.

Just move this part inside the module/build.gradle file.

android {
    compileSdkVersion 17
    buildToolsVersion '23.0.0'
}
dependencies {
    compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

response.setContentType("text/json");

//create the JSON string, I suggest using some framework.

String your_string;

out.write(your_string.getBytes("UTF-8"));

public void addNotification()
{
    NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(MainActivity.this);
    mBuilder.setSmallIcon(R.drawable.email);
    mBuilder.setContentTitle("Notification Alert, Click Me!");
    mBuilder.setContentText("Hi,This notification for you let me check");
    Intent notificationIntent = new Intent(this,MainActivity.class);
    PendingIntent conPendingIntent = PendingIntent.getActivity(this,0,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);

    mBuilder.setContentIntent(conPendingIntent);

    NotificationManager manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(0,mBuilder.build());
    Toast.makeText(MainActivity.this, "Notification", Toast.LENGTH_SHORT).show();

}

I suppose this works: a[a[:,1].argsort()]

This indicates the second column of a and sort it based on it accordingly.

For phpmydamin you can use following step

1. Go to python install path like

    cd C:\Users\Enamul\AppData\Local\Programs\Python\Python37-32\Scripts
   

2. Run the command pip install PyMySQL

3. In the python shell import library like import pymysql

4. connection to databasbe

    db = pymysql.connect(host='localhost',user='root',passwd='yourpassword', database="bd")
   

5. get cursor cursor = db.cursor()

6. Create table like

   cursor.execute("CREATE TABLE customers (name VARCHAR(255), address VARCHAR(255))")
   

The question does not make clear what exactly you want to achieve.

List has the append method, which appends its argument to the list:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.append(list_two)
>>> list_one
[1, 2, 3, [4, 5, 6]]

There's also the extend method, which appends items from the list you pass as an argument:

>>> list_one = [1,2,3]
>>> list_two = [4,5,6]
>>> list_one.extend(list_two)
>>> list_one
[1, 2, 3, 4, 5, 6]

And of course, there's the insert method which acts similarly to append but allows you to specify the insertion point:

>>> list_one.insert(2, list_two)
>>> list_one
[1, 2, [4, 5, 6], 3, 4, 5, 6]

To extend a list at a specific insertion point you can use list slicing (thanks, @florisla):

>>> l = [1, 2, 3, 4, 5]
>>> l[2:2] = ['a', 'b', 'c']
>>> l
[1, 2, 'a', 'b', 'c', 3, 4, 5]

List slicing is quite flexible as it allows to replace a range of entries in a list with a range of entries from another list:

>>> l = [1, 2, 3, 4, 5]
>>> l[2:4] = ['a', 'b', 'c'][1:3]
>>> l
[1, 2, 'b', 'c', 5]

First of all, a caveat. Why do you want to use telnet? telnet is an old protocol, unsafe and impractical for remote access. It's been (almost)totally replaced by ssh.

To answer your questions, it depends. It depends on the telnet client you use. If you use microsoft telnet, you can't. Microsoft telnet does not have any mean to send commands from a batch file or a command line.

file_name=test.log

# set first K lines:
K=1000

# line count (N): 
N=$(wc -l < $file_name)

# length of the bottom file:
L=$(( $N - $K ))

# create the top of file: 
head -n $K $file_name > top_$file_name

# create bottom of file: 
tail -n $L $file_name > bottom_$file_name

Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so

split -l 300000 file_name

will output xaa with 300k lines and xab with 100k lines, for an input with 400k lines.

In the newer version of datatables (version 1.10.7) it seems things have changed. The way to prevent DataTables from automatically sorting by the first column is to set the order option to an empty array.

You just need to add the following parameter to the DataTables options:

"order": [] 

Set up your DataTable as follows in order to override the default setting:

$('#example').dataTable( {
    "order": [],
    // Your other options here...
} );

That will override the default setting of "order": [[ 0, 'asc' ]].

You can find more details regarding the order option here: https://datatables.net/reference/option/order

I think this is a simple solution:

<div style="_x000D_
    display: inline-block;_x000D_

    top: 0;_x000D_
    bottom: 0;_x000D_
    left: 0;_x000D_
    right: 0;_x000D_
    width: 200px;_x000D_
    height: 100px;_x000D_
    margin: auto;_x000D_
    background-color: #f3f3f3;">Full Center ON Page_x000D_
</div>

Easy. Use .shape.

Overview

Why do we need the copy-and-swap idiom?

Any class that manages a resource (a wrapper, like a smart pointer) needs to implement The Big Three. While the goals and implementation of the copy-constructor and destructor are straightforward, the copy-assignment operator is arguably the most nuanced and difficult. How should it be done? What pitfalls need to be avoided?

The copy-and-swap idiom is the solution, and elegantly assists the assignment operator in achieving two things: avoiding code duplication, and providing a strong exception guarantee.

How does it work?

Conceptually, it works by using the copy-constructor's functionality to create a local copy of the data, then takes the copied data with a swap function, swapping the old data with the new data. The temporary copy then destructs, taking the old data with it. We are left with a copy of the new data.

In order to use the copy-and-swap idiom, we need three things: a working copy-constructor, a working destructor (both are the basis of any wrapper, so should be complete anyway), and a swap function.

A swap function is a non-throwing function that swaps two objects of a class, member for member. We might be tempted to use std::swap instead of providing our own, but this would be impossible; std::swap uses the copy-constructor and copy-assignment operator within its implementation, and we'd ultimately be trying to define the assignment operator in terms of itself!

(Not only that, but unqualified calls to swap will use our custom swap operator, skipping over the unnecessary construction and destruction of our class that std::swap would entail.)

An in-depth explanation

The goal

Let's consider a concrete case. We want to manage, in an otherwise useless class, a dynamic array. We start with a working constructor, copy-constructor, and destructor:

#include <algorithm> // std::copy
#include <cstddef> // std::size_t

class dumb_array
{
public:
    // (default) constructor
    dumb_array(std::size_t size = 0)
        : mSize(size),
          mArray(mSize ? new int[mSize]() : nullptr)
    {
    }

    // copy-constructor
    dumb_array(const dumb_array& other)
        : mSize(other.mSize),
          mArray(mSize ? new int[mSize] : nullptr),
    {
        // note that this is non-throwing, because of the data
        // types being used; more attention to detail with regards
        // to exceptions must be given in a more general case, however
        std::copy(other.mArray, other.mArray + mSize, mArray);
    }

    // destructor
    ~dumb_array()
    {
        delete [] mArray;
    }

private:
    std::size_t mSize;
    int* mArray;
};

This class almost manages the array successfully, but it needs operator= to work correctly.

A failed solution

Here's how a naive implementation might look:

// the hard part
dumb_array& operator=(const dumb_array& other)
{
    if (this != &other) // (1)
    {
        // get rid of the old data...
        delete [] mArray; // (2)
        mArray = nullptr; // (2) *(see footnote for rationale)

        // ...and put in the new
        mSize = other.mSize; // (3)
        mArray = mSize ? new int[mSize] : nullptr; // (3)
        std::copy(other.mArray, other.mArray + mSize, mArray); // (3)
    }

    return *this;
}

And we say we're finished; this now manages an array, without leaks. However, it suffers from three problems, marked sequentially in the code as (n).

1. The first is the self-assignment test. This check serves two purposes: it's an easy way to prevent us from running needless code on self-assignment, and it protects us from subtle bugs (such as deleting the array only to try and copy it). But in all other cases it merely serves to slow the program down, and act as noise in the code; self-assignment rarely occurs, so most of the time this check is a waste. It would be better if the operator could work properly without it.

2. The second is that it only provides a basic exception guarantee. If new int[mSize] fails, *this will have been modified. (Namely, the size is wrong and the data is gone!) For a strong exception guarantee, it would need to be something akin to:

   dumb_array& operator=(const dumb_array& other)
   {
       if (this != &other) // (1)
       {
           // get the new data ready before we replace the old
           std::size_t newSize = other.mSize;
           int* newArray = newSize ? new int[newSize]() : nullptr; // (3)
           std::copy(other.mArray, other.mArray + newSize, newArray); // (3)
   
           // replace the old data (all are non-throwing)
           delete [] mArray;
           mSize = newSize;
           mArray = newArray;
       }
   
       return *this;
   }
   

3. The code has expanded! Which leads us to the third problem: code duplication. Our assignment operator effectively duplicates all the code we've already written elsewhere, and that's a terrible thing.

In our case, the core of it is only two lines (the allocation and the copy), but with more complex resources this code bloat can be quite a hassle. We should strive to never repeat ourselves.

(One might wonder: if this much code is needed to manage one resource correctly, what if my class manages more than one? While this may seem to be a valid concern, and indeed it requires non-trivial try/catch clauses, this is a non-issue. That's because a class should manage one resource only!)

A successful solution

As mentioned, the copy-and-swap idiom will fix all these issues. But right now, we have all the requirements except one: a swap function. While The Rule of Three successfully entails the existence of our copy-constructor, assignment operator, and destructor, it should really be called "The Big Three and A Half": any time your class manages a resource it also makes sense to provide a swap function.

We need to add swap functionality to our class, and we do that as follows†:

class dumb_array
{
public:
    // ...

    friend void swap(dumb_array& first, dumb_array& second) // nothrow
    {
        // enable ADL (not necessary in our case, but good practice)
        using std::swap;

        // by swapping the members of two objects,
        // the two objects are effectively swapped
        swap(first.mSize, second.mSize);
        swap(first.mArray, second.mArray);
    }

    // ...
};

(Here is the explanation why public friend swap.) Now not only can we swap our dumb_array's, but swaps in general can be more efficient; it merely swaps pointers and sizes, rather than allocating and copying entire arrays. Aside from this bonus in functionality and efficiency, we are now ready to implement the copy-and-swap idiom.

Without further ado, our assignment operator is:

dumb_array& operator=(dumb_array other) // (1)
{
    swap(*this, other); // (2)

    return *this;
}

And that's it! With one fell swoop, all three problems are elegantly tackled at once.

Why does it work?

We first notice an important choice: the parameter argument is taken by-value. While one could just as easily do the following (and indeed, many naive implementations of the idiom do):

dumb_array& operator=(const dumb_array& other)
{
    dumb_array temp(other);
    swap(*this, temp);

    return *this;
}

We lose an important optimization opportunity. Not only that, but this choice is critical in C++11, which is discussed later. (On a general note, a remarkably useful guideline is as follows: if you're going to make a copy of something in a function, let the compiler do it in the parameter list.‡)

Either way, this method of obtaining our resource is the key to eliminating code duplication: we get to use the code from the copy-constructor to make the copy, and never need to repeat any bit of it. Now that the copy is made, we are ready to swap.

Observe that upon entering the function that all the new data is already allocated, copied, and ready to be used. This is what gives us a strong exception guarantee for free: we won't even enter the function if construction of the copy fails, and it's therefore not possible to alter the state of *this. (What we did manually before for a strong exception guarantee, the compiler is doing for us now; how kind.)

At this point we are home-free, because swap is non-throwing. We swap our current data with the copied data, safely altering our state, and the old data gets put into the temporary. The old data is then released when the function returns. (Where upon the parameter's scope ends and its destructor is called.)

Because the idiom repeats no code, we cannot introduce bugs within the operator. Note that this means we are rid of the need for a self-assignment check, allowing a single uniform implementation of operator=. (Additionally, we no longer have a performance penalty on non-self-assignments.)

And that is the copy-and-swap idiom.

What about C++11?

The next version of C++, C++11, makes one very important change to how we manage resources: the Rule of Three is now The Rule of Four (and a half). Why? Because not only do we need to be able to copy-construct our resource, we need to move-construct it as well.

Luckily for us, this is easy:

class dumb_array
{
public:
    // ...

    // move constructor
    dumb_array(dumb_array&& other) noexcept ††
        : dumb_array() // initialize via default constructor, C++11 only
    {
        swap(*this, other);
    }

    // ...
};

What's going on here? Recall the goal of move-construction: to take the resources from another instance of the class, leaving it in a state guaranteed to be assignable and destructible.

So what we've done is simple: initialize via the default constructor (a C++11 feature), then swap with other; we know a default constructed instance of our class can safely be assigned and destructed, so we know other will be able to do the same, after swapping.

(Note that some compilers do not support constructor delegation; in this case, we have to manually default construct the class. This is an unfortunate but luckily trivial task.)

Why does that work?

That is the only change we need to make to our class, so why does it work? Remember the ever-important decision we made to make the parameter a value and not a reference:

dumb_array& operator=(dumb_array other); // (1)

Now, if other is being initialized with an rvalue, it will be move-constructed. Perfect. In the same way C++03 let us re-use our copy-constructor functionality by taking the argument by-value, C++11 will automatically pick the move-constructor when appropriate as well. (And, of course, as mentioned in previously linked article, the copying/moving of the value may simply be elided altogether.)

And so concludes the copy-and-swap idiom.

Footnotes

*Why do we set mArray to null? Because if any further code in the operator throws, the destructor of dumb_array might be called; and if that happens without setting it to null, we attempt to delete memory that's already been deleted! We avoid this by setting it to null, as deleting null is a no-operation.

†There are other claims that we should specialize std::swap for our type, provide an in-class swap along-side a free-function swap, etc. But this is all unnecessary: any proper use of swap will be through an unqualified call, and our function will be found through ADL. One function will do.

‡The reason is simple: once you have the resource to yourself, you may swap and/or move it (C++11) anywhere it needs to be. And by making the copy in the parameter list, you maximize optimization.

††The move constructor should generally be noexcept, otherwise some code (e.g. std::vector resizing logic) will use the copy constructor even when a move would make sense. Of course, only mark it noexcept if the code inside doesn't throw exceptions.

You don't need JDK to run Java based programs. JDK is for development which stands for Java Development Kit.

You need JRE which should be there in Mac.

Try: java -jar Myjar_file.jar

EDIT: According to this article, for Mac OS 10

The Java runtime is no longer installed automatically as part of the OS installation.

Then, you need to install JRE to your machine.

Usually, git creates a hidden directory in project's root directory (.git/)

When you're working on a CMS, its possible you install modules/plugins carrying .git/ directory with git's metadata for the specific module/plugin

Quickest solution is to find all .git directories and keep only your root git metadata directory. If you do so, git will not consider those modules as project submodules.

If you work in MVC 4, you can watch this solution, it worked for me.

Add the following Application_Error method to my Global.asax:

protected void Application_Error(object sender, EventArgs e)
{
    Exception exception = Server.GetLastError();
    Server.ClearError();

    RouteData routeData = new RouteData();
    routeData.Values.Add("controller", "Error");
    routeData.Values.Add("action", "Index");
    routeData.Values.Add("exception", exception);

    if (exception.GetType() == typeof(HttpException))
    {
        routeData.Values.Add("statusCode", ((HttpException)exception).GetHttpCode());
    }
    else
    {
        routeData.Values.Add("statusCode", 500);
    }

    IController controller = new ErrorController();
    controller.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
    Response.End();

The controller itself is really simple:

public class ErrorController : Controller
{
    public ActionResult Index(int statusCode, Exception exception)
    {
        Response.StatusCode = statusCode;
        return View();
    }
}

If Apache was installed using NSIS installer it should have left an uninstaller. You should search inside Apache installation directory for executable named unistaller.exe or something like that. NSIS uninstallers support /S flag by default for silent uninstall. So you can run something like "C:\Program Files\<Apache installation dir here>\uninstaller.exe" /S

From NSIS documentation:

3.2.1 Common Options

/NCRC disables the CRC check, unless CRCCheck force was used in the script. /S runs the installer or uninstaller silently. See section 4.12 for more information. /D sets the default installation directory ($INSTDIR), overriding InstallDir and InstallDirRegKey. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported.

The issue could be with the response you are receiving from back-end. If it was working fine on the server then the problem could be with the response headers. Check the Access-Control-Allow-Origin (ACAO) in the response headers. Usually react's fetch API will throw fail to fetch even after receiving response when the response headers' ACAO and the origin of request won't match.

Nothing has worked. The solution for the issue is.

Yes, you can detect if the session is already running by checking isset($_SESSION). However the best answer is simply not to call session_start() more than once.

It should be called very early in your script, possibly even the first line, and then not called again.

If you have it in more than one place in your code then you're asking to get this kind of bug. Cut it down so it's only in one place and can only be called once.

This syntax is a little more flexible to handle events. Not only can you observe "changes", but also other types of events can be controlled here too by using one single event handler. You can do this by passing the list of events as arguments to the first parameter. See jQuery On

Secondly, .change() is a shortcut for .on( "change", handler ). See here. I prefer using .on() rather than .change because I have more control over the events.

Lastly, I'm simply showing an alternative syntax to attach the event to the element.

Use the CSS Class to prevent from Editing the Div Elements

CSS:

.divoverlay
{
position:absolute;
width:100%;
height:100%;
background-color:transparent;
z-index:1;
top:0;
}

JS:

$('#divName').append('<div class=divoverlay></div>');

Or add the class name in HTML Tag. It will prevent from editing the Div Elements.

I have this array as my request data from a HTML+Vue.js data grid/table:

[0] => Array
    (
        [item_id] => 1
        [item_no] => 3123
        [size] => 3e
    )
[1] => Array
    (
        [item_id] => 2
        [item_no] => 7688
        [size] => 5b
    )

And use this to validate which works properly:

$this->validate($request, [
    '*.item_id' => 'required|integer',
    '*.item_no' => 'required|integer',
    '*.size'    => 'required|max:191',
]);

Here's what you can do:

return View("another view name", anotherviewmodel);

The only parameter you need right now is ?u=<YOUR_URL>. All other data will be fetched from page or (better) from your open graph meta tags:

<meta property="og:url"                content="http://www.nytimes.com/2015/02/19/arts/international/when-great-minds-dont-think-alike.html" />
<meta property="og:type"               content="article" />
<meta property="og:title"              content="When Great Minds Don’t Think Alike" />
<meta property="og:description"        content="How much does culture influence creative thinking?" />
<meta property="og:image"              content="http://static01.nyt.com/images/2015/02/19/arts/international/19iht-btnumbers19A/19iht-btnumbers19A-facebookJumbo-v2.jpg" />

Example & description here

You can test your page for accordance in the debugger.

To clarify, the syntax is as follows for MongoDB version 4.0.x:

db.collection.update({},{$set: {"new_field*":1}},false,true)

Here is a working example adding a published field to the articles collection and setting the field's value to true:

db.articles.update({},{$set: {"published":true}},false,true)

1) Maybe oveflow: hidden; will do the trick?

2) You need to set the size of each div with the text and button so that each of these divs have the same height. Then for your button:

button {
  position: absolute;
  bottom: 0;
}

I need this for Unity in C# so I thought that it might be useful for some one. This is an example of passing a list of AudioSources to whatever function you want:

private void ChooseClip(GameObject audioSourceGameObject , List<AudioClip> sources) {
    audioSourceGameObject.GetComponent<AudioSource> ().clip = sources [0];
}

The best answer I use to receive data from server and display it

 constructor(props){
            super(props);
            this.state = {
                items2 : [{}],
                isLoading: true
            }

        }

componentWillMount (){
 axios({
            method: 'get',
            responseType: 'json',
            url: '....',

        })
            .then(response => {
                self.setState({
                    items2: response ,
                    isLoading: false
                });
                console.log("Asmaa Almadhoun *** : " + self.state.items2);
            })
            .catch(error => {
                console.log("Error *** : " + error);
            });
    })}



    render() {
       return(
       { this.state.isLoading &&
                    <i className="fa fa-spinner fa-spin"></i>

                }
                { !this.state.isLoading &&
            //external component passing Server data to its classes
                     <TestDynamic  items={this.state.items2}/> 
                }
         ) }

I suspect that this occurs after an attempt to undeploy your app. Do you ever kill off that thread that you've initialised during the init() process ? I would do this in the corresponding destroy() method.

The oddly named "blame" command does this. If you use Tortoise, it gives you a "from revision" dialog, then a file listing with a line by line indicator of Revision number and author next to it.

If you right click on the revision info, you can bring up a "Show log" dialog that gives full checkin information, along with other files that were part of the checkin.

You do not have many complex methods to import a python file from one folder to another. Just create a __init__.py file to declare this folder is a python package and then go to your host file where you want to import just type

from root.parent.folder.file import variable, class, whatever

I used this one document.querySelector('ElementClass').innerText = 'newtext';

The reason for this would be mostly due to the evil command pip install google. I was facing a similar issue for google-cloud, but the same steps are true for protobuf as well. Both of our issues deal with a namespace conflict over the 'google' namespace.

If you executed the pip install google command like I did then you are in the correct place. The google package is actually not owned by Google which can be confirmed by the command pip show google which outputs:

 Name: google
 Version: 1.9.3
 Summary: Python bindings to the Google search engine.
 Home-page: http://breakingcode.wordpress.com/
 Author: Mario Vilas
 Author-email: [email protected]
 License: UNKNOWN
 Location: <Path where this package is installed>
 Requires: beautifulsoup4

Because of this package, the google namespace is reserved and coincidentally google-cloud also expects namespace google > cloud and it results in a namespace collision for these two packages.

See in below screenshot namespace of google-protobuf as google > protobuf

Solution :- Unofficial google package need to be uninstalled which can be done by using pip uninstall google after this you can reinstall google-cloud using pip install google-cloud or protobuf using pip install protobuf

FootNotes :- Assuming you have installed the unofficial google package by mistake and you don't actually need it along with google-cloud package. If you need both unofficial google and google-cloud above solution won't work.

Furthermore, the unofficial 'google' package installs with it 'soupsieve' and 'beautifulsoup4'. You may want to also uninstall those packages.

Let me know if this solves your particular issue.

if the map is short you can do:

ImmutableMap.of(key, value, key2, value2); // ...up to five k-v pairs

If it is longer then:

ImmutableMap.builder()
   .put(key, value)
   .put(key2, value2)
   // ...
   .build();

@CommonsWare explained all things quite well. And we really should use the solution he proposed.

By the way, only information we could rely on when querying ContentResolver is a file's name and size as mentioned here: Retrieving File Information | Android developers

As you could see there is an interface OpenableColumns that contains only two fields: DISPLAY_NAME and SIZE.

In my case I was need to retrieve EXIF information about a JPEG image and rotate it if needed before sending to a server. To do that I copied a file content into a temporary file using ContentResolver and openInputStream()

On Solaris, you can use pstack(1) No changes to the python code are necessary. eg.

You can make both arguments lower case, and that way you will always end up with a case insensitive search.

var string2 = "AbC";

The DOM element style "property" is a readonly collection of all the style attributes defined on the element. (The collection property is readonly, not necessarily the items within the collection.)

You would be better off using the className "property" on the elements.

The shortest solution is:

const isCharDigit = n => n < 10;

You can apply these as well:

const isCharDigit = n => Boolean(++n);

const isCharDigit = n => '/' < n && n < ':';

const isCharDigit = n => !!++n;

if you want to check more than 1 chatacter, you might use next variants

Regular Expression:

const isDigit = n => /\d+/.test(n);

Comparison:

const isDigit = n => +n == n;

Check if it is not NaN

const isDigit = n => !isNaN(n);

The self name is used as the instance reference in class instances. It is only used in class method definitions. Don't use it in functions.

You also cannot reference local variables from other functions or methods with it. You can only reference instance or class attributes using it.

It depends on which Ruby version you use:

Ruby 2.4 and higher:

It just works, as since Ruby v2.4.0 supports Unicode case mapping:

"?????".capitalize #=> ?????

Ruby 2.3 and lower:

"maria".capitalize #=> "Maria"
"?????".capitalize #=> ?????

The problem is, it just doesn't do what you want it to, it outputs ????? instead of ?????.

If you're using Rails there's an easy workaround:

"?????".mb_chars.capitalize.to_s # requires ActiveSupport::Multibyte

Otherwise, you'll have to install the unicode gem and use it like this:

require 'unicode'

Unicode::capitalize("?????") #=> ?????

Ruby 1.8:

Be sure to use the coding magic comment:

#!/usr/bin/env ruby

puts "?????".capitalize

gives invalid multibyte char (US-ASCII), while:

#!/usr/bin/env ruby
#coding: utf-8

puts "?????".capitalize

works without errors, but also see the "Ruby 2.3 and lower" section for real capitalization.

The order() function fails when the column has levels or factor. It works properly when stringsAsFactors=FALSE is used in data.frame creation.

Copy Always to output directory is set then try the following:

 Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory);
 String Root = Directory.GetCurrentDirectory();

I would define $Version as a string to start with

[string]$Version

and if it's a param you can use the code posted by Samselvaprabu or if you would rather not present your users with an error you can do something like

while (-not($version)){
    $version = Read-Host "Enter the version ya fool!"
}
$request += "/" + $version

Try this,

<?php
$arr1=array('result1'=>'abcd','result2'=>'efg'); 
$arr2=array('result1'=>'hijk','result2'=>'lmn'); 
$arr3=array($arr1,$arr2); 
print (json_encode($arr3)); 
?>

In my experience, printf() hauls in more code than puts() regardless of the format string.

If I don't need the formatting, I don't use printf. However, fwrite to stdout works a lot faster than puts.

static const char my_text[] = "Using fwrite.\n";
fwrite(my_text, 1, sizeof(my_text) - sizeof('\0'), stdout);

Note: per comments, '\0' is an integer constant. The correct expression should be sizeof(char) as indicated by the comments.

If you're willing to remove the brew dependency, I would recommend nvm - I can't really recommend it over any other versioning solution because I haven't needed to try anything else. Having the ability to switch instantly between versions depending on which project you're working on is pretty valuable.

This should would work

List<TestA> testAList = new ArrayList<>();
List<TestB> testBList = new ArrayList<>()
testAList.addAll(new ArrayList<>(testBList));

The way we do this is by passing an argument in when starting the app with the environment. For instance:

node app.js -c dev

In app.js we then load dev.js as our configuration file. You can parse these options with optparse-js.

Now you have some core modules that are depending on this config file. When you write them as such:

var Workspace = module.exports = function(config) {
    if (config) {
         // do something;
    }
}

(function () {
    this.methodOnWorkspace = function () {

    };
}).call(Workspace.prototype);

And you can call it then in app.js like:

var Workspace = require("workspace");
this.workspace = new Workspace(config);

don't use -notLike, -notMatch with Regular-Expression works in one line:

Get-MailBoxPermission -id newsletter | ? {$_.User -NotMatch "NT-AUTORIT.*|.*-Admins|.*Administrators|.*Manage.*"}

sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf

sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

sudo service apache2 restart

Run above commands issue will be resolved.

Modify onClick() as follows:

@Override
public void onClick(View v) {
    if(v == btn) {
        canvas=sv.getHolder().lockCanvas();
        if(canvas!=null) {
            canvas.drawBitmap(bitmap, 100, 100, null);
            sv.getHolder().unlockCanvasAndPost(canvas);
        }
    } else if(v == btn1) {
        saveBitmapToInternalStorage(bitmap);
    }
}

There are several ways to enforce that btn must be pressed before btn1 so that the bitmap is painted before you attempt to save it.

I suggest that you initially disable btn1, and that you enable it when btn is clicked, like this:

if(v == btn) {
    ...
    btn1.setEnabled(true);
}

Responding to your question about List<T>:

List<T> is a class; specifying an interface allows more flexibility of implementation. A better question is "why not IList<T>?"

To answer that question, consider what IList<T> adds to ICollection<T>: integer indexing, which means the items have some arbitrary order, and can be retrieved by reference to that order. This is probably not meaningful in most cases, since items probably need to be ordered differently in different contexts.

I'm using get-json very simple to use:

$ npm install get-json --save

Import get-json

var getJSON = require('get-json')

To do a GET request you would do something like:

    console.log(response);
})

string connString = "<your connection string>";
string sql = "name of your sp";

using(SqlConnection conn = new SqlConnection(connString)) 
{

    {
        using(SqlDataAdapter da = new SqlDataAdapter()) 
        {
            da.SelectCommand = new SqlCommand(sql, conn);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;

            DataSet ds = new DataSet();   
            da.Fill(ds, "result_name");

            DataTable dt = ds.Tables["result_name"];

            foreach (DataRow row in dt.Rows) {
                //manipulate your data
            }
        }    
    } 
    catch(SQLException ex) 
    {
        Console.WriteLine("SQL Error: " + ex.Message);
    }
    catch(Exception e) 
    {
        Console.WriteLine("Error: " + e.Message);
    }
}

In VB.NET

<%=Html.ActionLink("Contact Us", "ContactUs", "Home", Nothing, New With {.class = "link"})%>

  If Me Is ComboBoxExt_c Then
    Set New_ = New ComboBoxExt_c
    Call New_.New_(cBox)
  Else
    Set v_cBox = cBox
  End If
End Function

As you can see the New_ constructor is called to both create and set the private members of the class (like init) only problem is, if called on the non-static instance it will re-initialize the private member. but that can be avoided by setting a flag.

Try this code.

In Java 8, it's now as simple as:

Best thing is to memorize balance equation in natural way.

Amount / Whole = Percentage / 100

usually You have one variable missing, in this case it is Amount

Amount / 10000 = 35.8 / 100

then you have high school math (proportion) to multiple outer from both sides and inner from both sides.

Amount * 100 = 358 000

Amount = 3580

It works the same in all languages and on paper. JavaScript is no exception.

Because other answers here claim that s denotes the area of the marker, I'm adding this answer to clearify that this is not necessarily the case.

Size in points^2

The argument s in plt.scatter denotes the markersize**2. As the documentation says

s : scalar or array_like, shape (n, ), optional
size in points^2. Default is rcParams['lines.markersize'] ** 2.

This can be taken literally. In order to obtain a marker which is x points large, you need to square that number and give it to the s argument.

So the relationship between the markersize of a line plot and the scatter size argument is the square. In order to produce a scatter marker of the same size as a plot marker of size 10 points you would hence call scatter( .., s=100).

import matplotlib.pyplot as plt

fig,ax = plt.subplots()

ax.plot([0],[0], marker="o",  markersize=10)
ax.plot([0.07,0.93],[0,0],    linewidth=10)
ax.scatter([1],[0],           s=100)

ax.plot([0],[1], marker="o",  markersize=22)
ax.plot([0.14,0.86],[1,1],    linewidth=22)
ax.scatter([1],[1],           s=22**2)

plt.show()

Connection to "area"

So why do other answers and even the documentation speak about "area" when it comes to the s parameter?

Of course the units of points**2 are area units.

• For the special case of a square marker, marker="s", the area of the marker is indeed directly the value of the s parameter.
• For a circle, the area of the circle is area = pi/4*s.
• For other markers there may not even be any obvious relation to the area of the marker.

In all cases however the area of the marker is proportional to the s parameter. This is the motivation to call it "area" even though in most cases it isn't really.

Specifying the size of the scatter markers in terms of some quantity which is proportional to the area of the marker makes in thus far sense as it is the area of the marker that is perceived when comparing different patches rather than its side length or diameter. I.e. doubling the underlying quantity should double the area of the marker.

What are points?

So far the answer to what the size of a scatter marker means is given in units of points. Points are often used in typography, where fonts are specified in points. Also linewidths is often specified in points. The standard size of points in matplotlib is 72 points per inch (ppi) - 1 point is hence 1/72 inches.

It might be useful to be able to specify sizes in pixels instead of points. If the figure dpi is 72 as well, one point is one pixel. If the figure dpi is different (matplotlib default is fig.dpi=100),

1 point == fig.dpi/72. pixels

While the scatter marker's size in points would hence look different for different figure dpi, one could produce a 10 by 10 pixels^2 marker, which would always have the same number of pixels covered:

import matplotlib.pyplot as plt

for dpi in [72,100,144]:

    fig,ax = plt.subplots(figsize=(1.5,2), dpi=dpi)
    ax.set_title("fig.dpi={}".format(dpi))

    ax.set_ylim(-3,3)
    ax.set_xlim(-2,2)

    ax.scatter([0],[1], s=10**2, 
               marker="s", linewidth=0, label="100 points^2")
    ax.scatter([1],[1], s=(10*72./fig.dpi)**2, 
               marker="s", linewidth=0, label="100 pixels^2")

    ax.legend(loc=8,framealpha=1, fontsize=8)

    fig.savefig("fig{}.png".format(dpi), bbox_inches="tight")

plt.show() 

If you are interested in a scatter in data units, check this answer.

I wonder why you find as solution the "white-space" with "nowrap" or "pre", it is not doing the correct behaviour: you force your text in a single line! The text should break lines, but not break words as default. This is caused by some css attributes: word-wrap, overflow-wrap, word-break, and hyphens. So you can have either:

word-break: break-all;
word-wrap: break-word;
overflow-wrap: break-word;
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;

So the solution is remove them, or override them with "unset" or "normal":

word-break: unset;
word-wrap: unset;
overflow-wrap: unset;
-webkit-hyphens: unset;
-moz-hyphens: unset;
-ms-hyphens: unset;
hyphens: unset;

USE INFORMATION_SCHEMA;
SELECT TABLE_NAME,
       COLUMN_NAME,
       CONSTRAINT_NAME,
       REFERENCED_TABLE_NAME,
       REFERENCED_COLUMN_NAME
FROM KEY_COLUMN_USAGE
WHERE TABLE_SCHEMA = "<your_database_name>" 
      AND TABLE_NAME = "<your_table_name>" 
      AND REFERENCED_COLUMN_NAME IS NOT NULL;

I think the wait/notify/notifyAll methods don't belong on the Object class as it pollutes all objects with methods that are rarely used. They make much more sense on a dedicated Lock class. So from this point of view, perhaps it's better to use a tool that is explicitly designed for the job at hand - ie ReentrantLock.

elementFromPoint() gets only the first element in DOM tree. This is mostly not enough for developers needs. To get more than one element at e.g. the current mouse pointer position, this is the function you need:

document.elementsFromPoint(x, y) . // Mind the 's' in elements

This returns an array of all element objects under the given point. Just pass the mouse X and Y values to this function.

More information is here: DocumentOrShadowRoot.elementsFromPoint()

For very old browsers which are not supported, you may use this answer as a fallback.
