Lexeme- A lexeme is a string of character that is the lowest level syntactic unit in the programming language.

Token- The token is a syntactic category that forms a class of lexemes that means which class the lexeme belong is it a keyword or identifier or anything else. One of the major tasks of the lexical analyzer is to create a pair of lexemes and tokens, that is to collect all the characters.

Let us take an example:-

if(y<= t)

y=y-3;

Lexeme                      Token

if                                       KEYWORD

(                                 LEFT PARENTHESIS

y                                     IDENTIFIER

< =                                 COMPARISON

t                                     IDENTIFIER

)                                RIGHT PARENTHESIS

y                                    IDENTIFIER

=                                   ASSGNMENT

y                                   IDENTIFIER

_                                   ARITHMATIC

3                                     INTEGER

;                                    SEMICOLON

Relation between Lexeme and Token

The first time you call it, you provide the string to tokenize to strtok. And then, to get the following tokens, you just give NULL to that function, as long as it returns a non NULL pointer.

The strtok function records the string you first provided when you call it. (Which is really dangerous for multi-thread applications)

When you register for a new website, often you are sent an email to activate your account. That email typically contains a link to click on. Part of that link, contains a token, the server knows about this token and can associate it with your account. The token would usually have an expiry date associated with it, so you may only have an hour to click on the link and activate your account. None of this would be possible with cookies or session variables, since its unknown what device or browser the customer is using to check emails.

showInventory(player); is passing a type as parameter. That's illegal, you need to pass an object.

For example, something like:

player p;
showInventory(p);  

I'm guessing you have something like this:

int main()
{
   player player;
   toDo();
}

which is awful. First, don't name the object the same as your type. Second, in order for the object to be visible inside the function, you'll need to pass it as parameter:

int main()
{
   player p;
   toDo(p);
}

and

std::string toDo(player& p) 
{
    //....
    showInventory(p);
    //....
}

Hi I followed following steps and I had been able to get the refresh token.

Authorization flow has two steps.

1. Is to obtain the authorization code using https://accounts.google.com/o/oauth2/auth? URL.

   For that a post request is sent providing following parameters. 'scope=' + SCOPE + '&client_id=' + CLIENTID + '&redirect_uri=' + REDIRECT + '&response_type=' + TYPE + '&access_type=offline' Providing above will receive a authorization code.

2. Retrieving AcessToken and RefreshToken using https://accounts.google.com/o/oauth2/token? URL. For that a post request is sent providing following parameters.

   "code" : code, "client_id" : CID, "client_secret" : CSECRET, "redirect_uri" : REDIRECT, "grant_type" : "authorization_code",

So in your first attempt once you authorize the permissions you will be able to get the Refresh token. Subsequent attempts will not provide the refresh token. If you want the token again the revoke the access in you application.

Hope this will help someone cheers :)

In PHP, use random_bytes(). Reason: your are seeking the way to get a password reminder token, and, if it is a one-time login credentials, then you actually have a data to protect (which is - whole user account)

So, the code will be as follows:

//$length = 78 etc
$token = bin2hex(random_bytes($length));

Update: previous versions of this answer was referring to uniqid() and that is incorrect if there is a matter of security and not only uniqueness. uniqid() is essentially just microtime() with some encoding. There are simple ways to get accurate predictions of the microtime() on your server. An attacker can issue a password reset request and then try through a couple of likely tokens. This is also possible if more_entropy is used, as the additional entropy is similarly weak. Thanks to @NikiC and @ScottArciszewski for pointing this out.

For more details see

• http://phpsecurity.readthedocs.org/en/latest/Insufficient-Entropy-For-Random-Values.html

API token is the same as password from API point of view, see source code uses token in place of passwords for the API.

Others is described in doc to use http basic authentication model

JJWT aims to be the easiest to use and understand JWT library for the JVM and Android:

https://github.com/jwtk/jjwt

After trying several solutions, this worked for me:

1. Go to IIS Manager
2. Open the Site
3. Click on Authentication
4. Edit Anonymous Authentication.
5. Select "Application pool identity"

example

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

you need to store the token while creating for 1st registration. When you retrieve data from login table you need to differentiate entered date with current date if it is more than 1 day (24 hours) you need to display message like your token is expired.

To generate key refer here

This works and I need to set the token only once in my app.js:

axios.defaults.headers.common = {
    'Authorization': 'Bearer ' + token
};

Then I can make requests in my components without setting the header again.

"axios": "^0.19.0",

Since this is the top-rated Stack Overflow Google search result for C++ split string or similar, I'll post a complete, copy/paste runnable example that shows both methods.

splitString uses stringstream (probably the better and easier option in most cases)

splitString2 uses find and substr (a more manual approach)

// SplitString.cpp

#include <iostream>
#include <vector>
#include <string>
#include <sstream>

// function prototypes
std::vector<std::string> splitString(const std::string& str, char delim);
std::vector<std::string> splitString2(const std::string& str, char delim);
std::string getSubstring(const std::string& str, int leftIdx, int rightIdx);


int main(void)
{
  // Test cases - all will pass
  
  std::string str = "ab,cd,ef";
  //std::string str = "abcdef";
  //std::string str = "";
  //std::string str = ",cd,ef";
  //std::string str = "ab,cd,";   // behavior of splitString and splitString2 is different for this final case only, if this case matters to you choose which one you need as applicable
  
  
  std::vector<std::string> tokens = splitString(str, ',');
  
  std::cout << "tokens: " << "\n";
  
  if (tokens.empty())
  {
    std::cout << "(tokens is empty)" << "\n";
  }
  else
  {
    for (auto& token : tokens)
    {
      if (token == "") std::cout << "(empty string)" << "\n";
      else std::cout << token << "\n";
    }
  }
    
  return 0;
}

std::vector<std::string> splitString(const std::string& str, char delim)
{
  std::vector<std::string> tokens;
  
  if (str == "") return tokens;
  
  std::string currentToken;
  
  std::stringstream ss(str);
  
  while (std::getline(ss, currentToken, delim))
  {
    tokens.push_back(currentToken);
  }
  
  return tokens;
}

std::vector<std::string> splitString2(const std::string& str, char delim)
{
  std::vector<std::string> tokens;
  
  if (str == "") return tokens;
  
  int leftIdx = 0;
  
  int delimIdx = str.find(delim);
  
  int rightIdx;
  
  while (delimIdx != std::string::npos)
  {
    rightIdx = delimIdx - 1;
    
    std::string token = getSubstring(str, leftIdx, rightIdx);
    tokens.push_back(token);
    
    // prep for next time around
    leftIdx = delimIdx + 1;
    
    delimIdx = str.find(delim, delimIdx + 1);
  }
  
  rightIdx = str.size() - 1;
  
  std::string token = getSubstring(str, leftIdx, rightIdx);
  tokens.push_back(token);
  
  return tokens;
}

std::string getSubstring(const std::string& str, int leftIdx, int rightIdx)
{
  return str.substr(leftIdx, rightIdx - leftIdx + 1);
}

make sure you are not including the jquery code between the

< script > < /script >

If so remove that and code will work fine, It worked in my case.

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

This worked for me:

r = requests.get('http://127.0.0.1:8000/api/ray/musics/', headers={'Authorization': 'Token 22ec0cc4207ebead1f51dea06ff149342082b190'})

My code uses user generated token.

You can execute raw sql in EF Core - Add this class to your project. This will allow you to execute raw SQL and get the raw results without having to define a POCO and a DBSet. See https://github.com/aspnet/EntityFramework/issues/1862#issuecomment-220787464 for original example.

Here's an example of how to use it:

// Execute a query.
using(var dr = await db.Database.ExecuteSqlQueryAsync("SELECT ID, Credits, LoginDate FROM SamplePlayer WHERE " +
                                                          "Name IN ('Electro', 'Nitro')"))
{
    // Output rows.
    var reader = dr.DbDataReader;
    while (reader.Read())
    {
        Console.Write("{0}\t{1}\t{2} \n", reader[0], reader[1], reader[2]);
    }
}

File sutest

#!/bin/bash
echo "uid is ${UID}"
echo "user is ${USER}"
echo "username is ${USERNAME}"

run it: `./sutest' gives me

uid is 500
user is stephenp
username is stephenp

but using sudo: sudo ./sutest gives

uid is 0
user is root
username is stephenp

So you retain the original user name in $USERNAME when running as sudo. This leads to a solution similar to what others posted:

#!/bin/bash
sudo -u ${USERNAME} normal_command_1
root_command_1
root_command_2
sudo -u ${USERNAME} normal_command_2
# etc.

Just sudo to invoke your script in the first place, it will prompt for the password once.

I originally wrote this answer on Linux, which does have some differences with OS X

OS X (I'm testing this on Mountain Lion 10.8.3) has an environment variable SUDO_USER when you're running sudo, which can be used in place of USERNAME above, or to be more cross-platform the script could check to see if SUDO_USER is set and use it if so, or use USERNAME if that's set.

Changing the original script for OS X, it becomes...

#!/bin/bash
sudo -u ${SUDO_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${SUDO_USER} normal_command_2
# etc.

A first stab at making it cross-platform could be...

#!/bin/bash
#
# set "THE_USER" to SUDO_USER if that's set,
#  else set it to USERNAME if THAT is set,
#   else set it to the string "unknown"
# should probably then test to see if it's "unknown"
#
THE_USER=${SUDO_USER:-${USERNAME:-unknown}}

sudo -u ${THE_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${THE_USER} normal_command_2
# etc.

This seems related to this: jQuery style not being applied in Safari

The solution suggested in the first response has worked well for me in these scenarios, namely: apply and remove a dummy class to the body after making the styling changes:

$('body').addClass('dummyclass').removeClass('dummyclass');

This forces safari to redraw.

You ask for quickest, but perhaps you mean "best" or "correct" or "typical"?

You also ask for commas to indicate thousands, but perhaps you mean "in normal human readable form according to the local custom of your user"?

You do it as so:

    int i = 35634646;
    String s = NumberFormat.getIntegerInstance().format(i);

Americans will get "35,634,646"

Germans will get "35.634.646"

Swiss Germans will get "35'634'646"

Correct way to do in Swift 4, If your frame as screen size is correct then put anywhere otherwise, important to write this in viewDidLayoutSubviews because we can get actual frame in viewDidLayoutSubviews

   override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        UIGraphicsBeginImageContext(view.frame.size)
        UIImage(named: "myImage")?.draw(in: self.view.bounds)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        view.backgroundColor = UIColor.init(patternImage: image!)
    }

#modal {
    display: flex;
    justify-content: space-around;
    align-items: center;
    position: fixed;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
}

inside it can be any element with diffenet width, height or without. all are centered.

I've installed and use VB6 for legacy projects many times on Windows 7.

What I have done and never came across any issues, is to install VB6, ignore the errors and then proceed to install the latest service pack, currently SP6.

Download here: http://www.microsoft.com/en-us/download/details.aspx?id=5721

Bonus: Also once you install it and realize that scrolling doesn't work, use the below: http://www.joebott.com/vb6scrollwheel.htm

//Inside the folder,

svn cleanup

svn update

//If are viewing any conflicts,

svn revert --depth infinity conflicted_filename

svn update conflicted_filename

svn update

One issue that I've come across is that to have a scrollbar a n element needs a height to be specified (and not as a %).

The trick is to nest another set of divs within each column, and set the column parent's display to flex with flex-direction: column.

<style>
    html, body {
        height: 100%;
        margin: 0;

        overflow-x: hidden;
        color: white;
    }

    .base-container {
        display: flex;
        flex: 1;
        flex-direction: column;
        width: 100%;
        height: 100%;
        overflow-y: hidden;
        align-items: stretch;
    }

    .title {
        flex: 0 0 50px;
        color: black;
    }

    .container {
        flex: 1 1 auto;
        display: flex;
        flex-direction: column;
    }

        .container .header {
            flex: 0 0 50px;
            background-color: red;
        }

        .container .body {

                display: flex;
                flex-direction: column;
                flex: 0 0 80px;
                background-color: blue;
            }

                    overflow-y: auto;
                    height: 100px;
                }
                .container .body .main .content.noscrollbar {
                    overflow-y: hidden;
                }

            .container .body .main {
                display: flex;
                flex-direction: column;
                flex: 1 1 auto;
                background-color: green;
            }

            .container .body .right {
                display: flex;
                flex-direction: column;
                flex: 0 0 300px;
                background-color: yellow;
                color: black;
            }

    .test {
        margin: 5px 5px;
        border: 1px solid white;
        height: calc(100% - 10px);
    }
</style>

And here's the html:

<div class="base-container">
    <div class="title">
        Title
    </div>
    <div class="container">
        <div class="header">

If your pdf is text-based and not a scanned document (i.e. if you can click and drag to select text in your table in a PDF viewer), then you can use the module camelot-py with

import camelot
tables = camelot.read_pdf('foo.pdf')

You then can choose how you want to save the tables (as csv, json, excel, html, sqlite), and whether the output should be compressed in a ZIP archive.

tables.export('foo.csv', f='csv', compress=False)

Edit: tabula-py appears roughly 6 times faster than camelot-py so that should be used instead.

import camelot
import cProfile
import pstats
import tabula

cmd_tabula = "tabula.read_pdf('table.pdf', pages='1', lattice=True)"
prof_tabula = cProfile.Profile().run(cmd_tabula)
time_tabula = pstats.Stats(prof_tabula).total_tt

cmd_camelot = "camelot.read_pdf('table.pdf', pages='1', flavor='lattice')"
prof_camelot = cProfile.Profile().run(cmd_camelot)
time_camelot = pstats.Stats(prof_camelot).total_tt

print(time_tabula, time_camelot, time_camelot/time_tabula)

gave

That's a good question! You may get into troubles if you invoke API that uses generics and want to assign or return that result with a different subtype of the generic type. Java 8 helps to transform:

    List<String> input = new LinkedList<>(Arrays.asList("a", "b", "c"));
    List<CharSequence> result;
    
//    result = input; // <-- Type mismatch: cannot convert from List<String> to List<CharSequence>
    result = input.stream().collect(Collectors.toList());
    
    System.out.println(result);

Google Map API request and parse DirectionsResponse with C#, change the json in your url to xml and use the following code to turn the result into a usable C# Generic List Object.

Took me a while to make. But here it is

var url = String.Format("http://maps.googleapis.com/maps/api/directions/xml?...");

I hope this will help someone.

Use tolist():

import numpy as np
>>> np.array([[1,2,3],[4,5,6]]).tolist()
[[1, 2, 3], [4, 5, 6]]

Note that this converts the values from whatever numpy type they may have (e.g. np.int32 or np.float32) to the "nearest compatible Python type" (in a list). If you want to preserve the numpy data types, you could call list() on your array instead, and you'll end up with a list of numpy scalars. (Thanks to Mr_and_Mrs_D for pointing that out in a comment.)

In Access, click Create > Module and paste in the following code

Public Function ConvertMyStringToDateTime(strIn As String) As Date
ConvertMyStringToDateTime = CDate( _
        Mid(strIn, 1, 4) & "-" & Mid(strIn, 5, 2) & "-" & Mid(strIn, 7, 2) & " " & _
        Mid(strIn, 9, 2) & ":" & Mid(strIn, 11, 2) & ":" & Mid(strIn, 13, 2))
End Function

Hit Ctrl+S and save the module as modDateConversion.

Now try using a query like

Select * from Events
Where Events.[Date] > ConvertMyStringToDateTime("20130423014854")

--- Edit ---

Alternative solution avoiding user-defined VBA function:

SELECT * FROM Events
WHERE Format(Events.[Date],'yyyyMMddHhNnSs') > '20130423014854'

Simple php script worked for me.

Export:

// add all job codes in the array
$jobs = array("job1", "job2", "job3");

foreach ($jobs as $value)
{
    fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
    $path = "http://server1:8080/jenkins/job/".$value."/config.xml";
    $myfile = fopen($value.".xml", "w");
    fwrite($myfile, file_get_contents($path));
    fclose($myfile);
}

Import:

<?php

// add all job codes in the array
$jobs = array("job1", "job2", "job3");

foreach ($arr as $value)
{
    fwrite(STDOUT, $value. " \n") or die("Unable to open file!");
    $cmd = "java -jar jenkins-cli.jar -s http://server2:8080/jenkins/ create-job ".$value." < ".$value.".xml";
    echo exec($cmd);
}

I experienced this problem when the .BAK file was temporarily stored in a folder encrypted with BitLocker. It retained the encryption after it was moved to a different folder.

The NETWORK SERVICE account was unable to decrypt the file and gave this thoroughly informative error message.

Removing BitLocker encryption (by unchecking "Encrypt contents to secure data" in the file properties) on the .BAK file resolved the issue.

Installing framework 4.0 redistributable is also enough to create application pool. You can download it from here.

As a fallback solution, you could wrap your classes in a parent element like this:

<div>
    <div>This text should appear as normal</div>
    <p>This text should be blue.</p>
    <div>
        <!-- first-child / first-of-type starts from here -->
        <p class="myclass1">This text should appear red.</p>
        <p class="myclass2">This text should appear green.</p>
    </div>
</div>

you can use pattern matcher as well, which will replace all in one shot.

Pattern keyPattern = Pattern.compile(key); Matcher matcher = keyPattern.matcher(str); String nerSrting = matcher.replaceAll(value);

You do not need to clear focus, just add this code where you want to focus

 time_statusTV.setFocusable(true);
 time_statusTV.requestFocus();
 InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);
 imm.showSoftInput( time_statusTV, 0);

If you're struggling with such an issue using Lollipop (Android 5.*) probably you guys should do one simple step that I'd done before my ADB (I use Ubuntu) got my phone:

Change USB PC connection type to "Send images(PTP)" (before I've been using "Media device(MTP)")

Just like this:

And don't forget to activate checkbox "USB debugging".

It's different in every browser.

Some years ago, what you tried, was right. But nowadays it is regarded as a security risk by browser vendors that one cannot see the browsers address bar (for phishing reasons) and so they (or most of them) made the decision to always show the browser address bar. Which is good in my eyes.

The below method worked for me, Kudos to github user : midnightcodr

Make sure You remove any nodejs/npm packages already installed.

sudo apt-get purge nodejs

sudo apt-get purge npm

Now Install Node js using the command below( Thanks to midnightcodr on github)

curl -L https://raw.github.com/midnightcodr/rpi_node_install/master/setup.sh | bash -s 0.10.24

Note that you can invoke node with command node and not nodejs.

Once node is installed , Install npm

sudo apt-get install npm

I had also faced the same issue and it got resolved by commenting the version element in POM.xml as show.

If you are looking for a quick and manual process with UI. I always use Mozilla Firefox to convert from PFX to P12. First import the certificate into the Firefox browser (Options > Privacy & Security > View Certificates... > Import...). Once installed, perform the export to create the P12 file by choosing the certificate name from the Certificate Manager and then click Backup... and enter the file name and then enter the password.

You can set a control variable in vars files located in group_vars/ or directly in hosts file like this:

[vagrant:vars]
test_var=true

[location-1]
192.168.33.10 hostname=apollo

[location-2]
192.168.33.20 hostname=zeus

[vagrant:children]
location-1
location-2

And run tasks like this:

- name: "test"
  command: "echo {{test_var}}"
  when: test_var is defined and test_var

In addition @Fredrik Mörk's great answer on strings, to add localization to a form do the following:

• Set the form's property "Localizable" to true
• Change the form's Language property to the language you want (from a nice drop-down with them all in)
• Translate the controls in that form and move them about if need be (squash those really long full French sentences in!)

Edit: This MSDN article on Localizing Windows Forms is not the original one I linked ... but might shed more light if needed. (the old one has been taken away)

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

Well, std::string is a class, const char * is a pointer. Those are two different things. It's easy to get from string to a pointer (since it typically contains one that it can just return), but for the other way, you need to create an object of type std::string.

My recommendation: Functions that take constant strings and don't modify them should always take const char * as an argument. That way, they will always work - with string literals as well as with std::string (via an implicit c_str()).

I know this is a very old question, but from twig 1.6 you can use the slice filter;

{{ myentity.text|slice(0, 50) ~ '...' }}

The second part from the tilde is optional for if you want to add something for example the ellipsis.

Edit: My bad, I see the most up-voted answer do make use of the slice filter.

I second Dave's idea. I'm not always fond of pivot tables, but in this case they are pretty straightforward to use.

Here are my results:

It was so simple to create it that I have even recorded a macro in case you need to do this with VBA:

Sub Macro2()
'
' Macro2 Macro
'

'
    Range("Table1[[#All],[DATA]]").Select
    ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _
        "Table1", Version:=xlPivotTableVersion14).CreatePivotTable TableDestination _
        :="Sheet3!R3C7", TableName:="PivotTable4", DefaultVersion:= _
        xlPivotTableVersion14
    Sheets("Sheet3").Select
    Cells(3, 7).Select
    With ActiveSheet.PivotTables("PivotTable4").PivotFields("DATA")
        .Orientation = xlRowField
        .Position = 1
    End With
    ActiveSheet.PivotTables("PivotTable4").AddDataField ActiveSheet.PivotTables( _
        "PivotTable4").PivotFields("DATA"), "Count of DATA", xlCount
End Sub

Based on your comments, you would be better off with Text-finder plugin.

It allows to search file(s), as well as console, for a regular expression and then set the build either unstable or failed if found.

As for the Groovy, you can use the following to access ${WORKSPACE} environment variable:
def workspace = manager.build.getEnvVars()["WORKSPACE"]

If you have not ejected from CRA yet, you can't easily modify your webpack config. The config file is hidden in node_modules/react_scripts/config/webpackDevServer.config.js. You are discouraged to change that config.

Instead, you can just set the environment variable DANGEROUSLY_DISABLE_HOST_CHECK to true to disable the host check:

DANGEROUSLY_DISABLE_HOST_CHECK=true yarn start  
# or the equivalent npm command

It's just the required syntax:

void Func(int (&myArray)[100])

^ Pass array of 100 int by reference the parameters name is myArray;

void Func(int* myArray)

^ Pass an array. Array decays to a pointer. Thus you lose size information.

void Func(int (*myFunc)(double))

^ Pass a function pointer. The function returns an int and takes a double. The parameter name is myFunc.

We've always used an

if(iserror(vlookup,"n/a",vlookup))

Excel 2007 introduced IfError which allows you to do the vlookup and add output in case of error, but that doesn't help you with 2003...

The accepted answer is correct. I would like to provide an example to elaborate it a bit to those who aren't familiar with promise.

Example:

In my example, I need to replace the src attributes of img tags with different mirror urls if available before rendering the content.

var img_tags = content.querySelectorAll('img');

function checkMirrorAvailability(url) {

    // blah blah 

    return promise;
}

function changeSrc(success, y, response) {
    if (success === true) {
        img_tags[y].setAttribute('src', response.mirror_url);
    } 
    else {
        console.log('No mirrors for: ' + img_tags[y].getAttribute('src'));
    }
}

var promise_array = [];

for (var y = 0; y < img_tags.length; y++) {
    var img_src = img_tags[y].getAttribute('src');

    promise_array.push(
        checkMirrorAvailability(img_src)
        .then(

            // a callback function only accept ONE argument. 
            // Here, we use  `.bind` to pass additional arguments to the
            // callback function (changeSrc).

            // successCallback
            changeSrc.bind(null, true, y),
            // errorCallback
            changeSrc.bind(null, false, y)
        )
    );
}

$q.all(promise_array)
.then(
    function() {
        console.log('all promises have returned with either success or failure!');
        render(content);
    }
    // We don't need an errorCallback function here, because above we handled
    // all errors.
);

Explanation:

From AngularJS docs:

The then method:

then(successCallback, errorCallback, notifyCallback) – regardless of when the promise was or will be resolved or rejected, then calls one of the success or error callbacks asynchronously as soon as the result is available. The callbacks are called with a single argument: the result or rejection reason.

$q.all(promises)

Combines multiple promises into a single promise that is resolved when all of the input promises are resolved.

The promises param can be an array of promises.

About bind(), More info here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind

Here is the sample code.

System.IO.MemoryStream ms = new System.IO.MemoryStream();
System.IO.StreamWriter writer = new System.IO.StreamWriter(ms);
writer.Write("Hello its my sample file");
writer.Flush();
writer.Dispose();
ms.Position = 0;

System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Text.Plain);
System.Net.Mail.Attachment attach = new System.Net.Mail.Attachment(ms, ct);
attach.ContentDisposition.FileName = "myFile.txt";

// I guess you know how to send email with an attachment
// after sending email
ms.Close();

Edit 1

You can specify other file types by System.Net.Mime.MimeTypeNames like System.Net.Mime.MediaTypeNames.Application.Pdf

Based on Mime Type you need to specify correct extension in FileName for instance "myFile.pdf"

You could as well get more easy-to-interpret picture of where tags point to using

git log --graph |git name-rev --stdin --tags |less

and then scroll to the tag you're looking for via /.

More compact view (--pretty=oneline) plus all heads (-a) could also help:

git log -a --pretty=oneline --graph |git name-rev --stdin --tags |less

Looks a bit terrifying, but could also be aliased in ~/.gitconfig if necessary.

~/.gitconfig

[alias]
ls-tags = !git log -a --pretty=oneline --graph |git name-rev --stdin --tags |less

All above answers are correct here is another way with screenshot too.

From Chrome :

1. Right click "inspect" on the item you are trying to find the xpath
2. Right click on the highlighted area on the console.

This blog explains your problem neatly Async Best Practices.

The gist of it being you shouldn't use void as return for an async method, unless it's an async event handler, this is bad practice because it doesn't allow exceptions to be caught ;-).

Best practice would be to change the return type to Task. Also, try to code async all the way trough, make every async method call and be called from async methods. Except for a Main method in a console, which can't be async (before C# 7.1).

You will run into deadlocks with GUI and ASP.NET applications if you ignore this best practice. The deadlock occurs because these applications runs on a context that allows only one thread and won't relinquish it to the async thread. This means the GUI waits synchronously for a return, while the async method waits for the context: deadlock.

This behaviour won't happen in a console application, because it runs on context with a thread pool. The async method will return on another thread which will be scheduled. This is why a test console app will work, but the same calls will deadlock in other applications...

You should use data.response in your JS instead of json.response.

There is nothing wrong with your code. The problem is not visible form here.

1. Check if after the submit, the script is called at all.

2. Have a look at what is submitted: var_dump($_REQUEST)

Just add the percentage value into a variable and use #{$variable} for example

$twentyFivePercent:25%;
.selector {
    height: calc(#{$twentyFivePercent} - 5px);
}

Did you try using t.Text?

So, strictly speaking, the "type of a variable" is always present, and can be passed around as a type parameter. For example:

val x = 5
def f[T](v: T) = v
f(x) // T is Int, the type of x

But depending on what you want to do, that won't help you. For instance, may want not to know what is the type of the variable, but to know if the type of the value is some specific type, such as this:

val x: Any = 5
def f[T](v: T) = v match {
  case _: Int    => "Int"
  case _: String => "String"
  case _         => "Unknown"
}
f(x)

Here it doesn't matter what is the type of the variable, Any. What matters, what is checked is the type of 5, the value. In fact, T is useless -- you might as well have written it def f(v: Any) instead. Also, this uses either ClassTag or a value's Class, which are explained below, and cannot check the type parameters of a type: you can check whether something is a List[_] (List of something), but not whether it is, for example, a List[Int] or List[String].

Another possibility is that you want to reify the type of the variable. That is, you want to convert the type into a value, so you can store it, pass it around, etc. This involves reflection, and you'll be using either ClassTag or a TypeTag. For example:

val x: Any = 5
import scala.reflect.ClassTag
def f[T](v: T)(implicit ev: ClassTag[T]) = ev.toString
f(x) // returns the string "Any"

A ClassTag will also let you use type parameters you received on match. This won't work:

def f[A, B](a: A, b: B) = a match {
  case _: B => "A is a B"
  case _ => "A is not a B"
}

But this will:

val x = 'c'
val y = 5
val z: Any = 5
import scala.reflect.ClassTag
def f[A, B: ClassTag](a: A, b: B) = a match {
  case _: B => "A is a B"
  case _ => "A is not a B"
}
f(x, y) // A (Char) is not a B (Int)
f(x, z) // A (Char) is a B (Any)

Here I'm using the context bounds syntax, B : ClassTag, which works just like the implicit parameter in the previous ClassTag example, but uses an anonymous variable.

One can also get a ClassTag from a value's Class, like this:

val x: Any = 5
val y = 5
import scala.reflect.ClassTag
def f(a: Any, b: Any) = {
  val B = ClassTag(b.getClass)
  ClassTag(a.getClass) match {
    case B => "a is the same class as b"
    case _ => "a is not the same class as b"
  }
}
f(x, y) == f(y, x) // true, a is the same class as b

A ClassTag is limited in that it only covers the base class, but not its type parameters. That is, the ClassTag for List[Int] and List[String] is the same, List. If you need type parameters, then you must use a TypeTag instead. A TypeTag however, cannot be obtained from a value, nor can it be used on a pattern match, due to JVM's erasure.

Examples with TypeTag can get quite complex -- not even comparing two type tags is not exactly simple, as can be seen below:

import scala.reflect.runtime.universe.TypeTag
def f[A, B](a: A, b: B)(implicit evA: TypeTag[A], evB: TypeTag[B]) = evA == evB
type X = Int
val x: X = 5
val y = 5
f(x, y) // false, X is not the same type as Int

Of course, there are ways to make that comparison return true, but it would require a few book chapters to really cover TypeTag, so I'll stop here.

Finally, maybe you don't care about the type of the variable at all. Maybe you just want to know what is the class of a value, in which case the answer is rather simple:

val x = 5
x.getClass // int -- technically, an Int cannot be a class, but Scala fakes it

It would be better, however, to be more specific about what you want to accomplish, so that the answer can be more to the point.

Everything that other solutions have, but with a little validation

// value = '675-805-714'
const validateNumberInput = (value) => { 
    let numberPattern = /\d+/g 
    let numbers = value.match(numberPattern)

    if (numbers === null) {
        return 0
    }  

    return parseInt(numbers.join([]))
}
// 675805714

Show all variable in Windows system and Unix system is different, you can define a function to call it every time.

def showSystemVariables(){    
   if(isUnix()){
     sh 'env'
   } else {
     bat 'set'
   }
}

I will call this function first to show all variables in all pipline script

stage('1. Show all variables'){
     steps {
         script{            
              showSystemVariables()
         }
     }
} 

The thread module does work simultaneously unlike multiprocess, but the timing is a bit off. The code below prints a "1" and a "2". These are called by different functions respectively. I did notice that when printed to the console, they would have slightly different timings.

from threading import Thread

def one():
    while(1 == num):
        print("1")
        time.sleep(2)
    
def two():
    while(1 == num):
        print("2")
        time.sleep(2)


p1 = Thread(target = one)
p2 = Thread(target = two)

p1.start()
p2.start()

Output: (Note the space is for the wait in between printing)

1
2

2
1

12
   
21

12
   
1
2

Not sure if there is a way to correct this, or if it matters at all. Just something I noticed.

to simply remove it, paste your xml file into notepad, you'll see the extra character before the first tag. Remove it & paste back into your file - bof

You need to use an Expanded Widget. But, if your button is on a column, the Expanded Widget fills the rest of the column. So, you need to enclose the Expanded Widget within a row.

Row(children: <Widget>[
Expanded(
  flex: 1,
  child: RaisedButton(
    child: Text("Your Text"),
      onPressed: _submitForm,
    ),
  ),),])

First things first, you need to check to make sure that localStorage is enabled. I would recommend doing it like this:

var localStorageEnabled = false;
try { localStorageEnabled = !!localStorage; } catch(e) {};

Yes, you can (in some cases) just check to see if the localStorage is a member of the window object. However, there are iframe sandboxing options (among other things) that will throw an exception if you even attempt to access the index 'localStorage'. Thus, for best-practices reasons, this is the best way to check to see if the localStorage is enabled. Then, you can just clear the localStorage like so.

if (localStorageEnabled) localStorage.clear();

For example, you could clear the localStorage after an error occurs in webkit browsers like so.

// clears the local storage upon error
if (localStorageEnabled)
  window.onerror = localStorage.clear.bind(localStorage);

In the above example, you need the .bind(window) because without it, the localStorage.clear function will run in the context of the window object, instead of the localStorage object making it silently fail. To demonstrate this, look at the below example:

window.onerror = localStorage.clear;

is the same as:

window.onerror = function(){
    localStorage.clear.call(window);
}

Here's the strsplit solution if s is a vector:

> s <- c("TGAS_1121", "MGAS_1432")
> s1 <- sapply(strsplit(s, split='_', fixed=TRUE), function(x) (x[2]))
> s1
[1] "1121" "1432"

clock() has a often a pretty lousy resolution. If you want to measure time at the millisecond level, one alternative is to use clock_gettime(), as explained in this question.

(Remember that you need to link with -lrt on Linux).

Console.TreatControlCAsInput = true; has worked for me.

You can use the shell for this purpose.

Set shl = CreateObject("WScript.Shell") 
shl.Run "cmd mkdir YourDir" & copy "

In my case. I had the error because I forgot to make a commit after create a repository on github into an existing project. So I solved:

git add .
git commit -m"commentary"

Then I was able to type:

git push -u origin master

string[] str = new string[]{"1","2"};
string[] str = new string[4];

The full command would be something like below, notice the quotes

icacls "c:\inetpub\wwwroot\tmp" /grant "IIS AppPool\DefaultAppPool:F"

I had similar problem, login was done with ajax, but browsers (firefox, chrome, safari and IE 7-10) would not offer to save password if form (#loginForm) is submitted with ajax.

As a SOLUTION I have added hidden submit input (#loginFormHiddenSubmit) to form that was submitted by ajax and after ajax call would return success I would trigger a click to hidden submit input. The page any way needed to refreshed. The click can be triggered with:

jQuery('#loginFormHiddenSubmit').click();

Reason why I have added hidden submit button is because:

jQuery('#loginForm').submit();

would not offer to save password in IE (although it has worked in other browsers).

According to C99 standard, section 6.5.5 Multiplicative operators, the following is required:

(a / b) * b + a % b = a

Conclusion

The sign of the result of a remainder operation, according to C99, is the same as the dividend's one.

Let's see some examples (dividend / divisor):

When only dividend is negative

(-3 / 2) * 2  +  -3 % 2 = -3

(-3 / 2) * 2 = -2

(-3 % 2) must be -1

When only divisor is negative

(3 / -2) * -2  +  3 % -2 = 3

(3 / -2) * -2 = 2

(3 % -2) must be 1

When both divisor and dividend are negative

(-3 / -2) * -2  +  -3 % -2 = -3

(-3 / -2) * -2 = -2

(-3 % -2) must be -1

6.5.5 Multiplicative operators

Syntax

1. multiplicative-expression:
   • cast-expression
   • multiplicative-expression * cast-expression
   • multiplicative-expression / cast-expression
   • multiplicative-expression % cast-expression

Constraints

2. Each of the operands shall have arithmetic type. The operands of the % operator shall have integer type.

Semantics

3. The usual arithmetic conversions are performed on the operands.

4. The result of the binary * operator is the product of the operands.

5. The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder. In both operations, if the value of the second operand is zero, the behavior is undefined.

6. When integers are divided, the result of the / operator is the algebraic quotient with any fractional part discarded [1]. If the quotient a/b is representable, the expression (a/b)*b + a%b shall equal a.

[1]: This is often called "truncation toward zero".

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

>>> a=$("#communitymode")[0]
<input id="communitymode" type="checkbox" name="communitymode">

We have set up a solution for Team Foundation Server Source Control (not SourceSafe as you mention) similar to what Grant suggests; scheduled TF Get, Search Server Express. However the IFilter used for C# files (text) was not giving the results we wanted, so we convert source files to .htm files. We can now add additional meta-data to the files such as:

• Author (we define it as the person that last checked in the file)
• Color coding (on our todo-list)
• Number of changes indicating potential design problems (on our todo-list)
• Integrate with the VSTS IDE like Koders SmartSearch feature
• etc.

We would however prefer a protocolhandler for TFS Source Control, and a dedicated source code IFilter for a much more targeted solution.

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

To update a table in your .dbml-diagram with, for example, added columns, do this:

1. Update your SQL Server Explorer window.
2. Drag the "new" version of your table into the .dbml-diagram (report1 in the picture below).

3. Mark the added columns in the new version of the table, press Ctrl+C to copy the added columns.

4. Click the "old" version of your table and press Ctrl+V to paste the added columns into the already present version of the table.

From http://www.faqs.org/docs/diveintopython/fileinfo_private.html

Strictly speaking, private methods are accessible outside their class, just not easily accessible. Nothing in Python is truly private; internally, the names of private methods and attributes are mangled and unmangled on the fly to make them seem inaccessible by their given names. You can access the __parse method of the MP3FileInfo class by the name _MP3FileInfo__parse. Acknowledge that this is interesting, then promise to never, ever do it in real code. Private methods are private for a reason, but like many other things in Python, their privateness is ultimately a matter of convention, not force.

If you need in different Layer :

Create a Static Class and expose all config properties on that layer as below :

using Microsoft.Extensions.Configuration;_x000D_
using System.IO;_x000D_
_x000D_
namespace Core.DAL_x000D_
{_x000D_
    public static class ConfigSettings_x000D_
    {_x000D_
        public static string conStr1 { get ; }_x000D_
        static ConfigSettings()_x000D_
        {_x000D_
            var configurationBuilder = new ConfigurationBuilder();_x000D_
            string path = Path.Combine(Directory.GetCurrentDirectory(), "appsettings.json");_x000D_
            configurationBuilder.AddJsonFile(path, false);_x000D_
            conStr1 = configurationBuilder.Build().GetSection("ConnectionStrings:ConStr1").Value;_x000D_
        }_x000D_
    }_x000D_
}

You can write your possible date formats in array and parse date as following:

public static void Main(string[] args)
        {
            string dd = "12/31/2015"; //or 31/12/2015
            DateTime startDate;
            string[] formats = { "dd/MM/yyyy", "dd/M/yyyy", "d/M/yyyy", "d/MM/yyyy",
                                "dd/MM/yy", "dd/M/yy", "d/M/yy", "d/MM/yy", "MM/dd/yyyy"};
            
            DateTime.TryParseExact(dd, formats, 
            System.Globalization.CultureInfo.InvariantCulture,
            System.Globalization.DateTimeStyles.None, out startDate);
                
            Console.WriteLine(startDate.ToString("yyyy-MM-dd"));
            
        }

I added an extension to Exception which returns the line, column, method, filename and message:

public static class Extensions
{
    public static string ExceptionInfo(this Exception exception)
    {

        StackFrame stackFrame = (new StackTrace(exception, true)).GetFrame(0);
        return string.Format("At line {0} column {1} in {2}: {3} {4}{3}{5}  ",
           stackFrame.GetFileLineNumber(), stackFrame.GetFileColumnNumber(),
           stackFrame.GetMethod(), Environment.NewLine, stackFrame.GetFileName(),
           exception.Message);

    }
}

I here have a nice and versatile solution with a fallback:

<script type="text/javascript">
    var audiotypes={
        "mp3": "audio/mpeg",
        "mp4": "audio/mp4",
        "ogg": "audio/ogg",
        "wav": "audio/wav"
    }

    function ss_soundbits(sound){
        var audio_element = document.createElement('audio')
        if (audio_element.canPlayType){
            for (var i=0; i<arguments.length; i++){
                var source_element = document.createElement('source')
                source_element.setAttribute('src', arguments[i])
                if (arguments[i].match(/\.(\w+)$/i))
                    source_element.setAttribute('type', audiotypes[RegExp.$1])
                audio_element.appendChild(source_element)
            }
            audio_element.load()
            audio_element.playclip=function(){
                audio_element.pause()
                audio_element.currentTime=0
                audio_element.play()
            }
            return audio_element
        }
    }
</script>

After that you can initialize as many audio as you like:

<script type="text/javascript" >
    var clicksound  = ss_soundbits('your/path/to/click.ogg', "your/path/to/click.mp3");
    var plopsound  = ss_soundbits('your/path/to/plopp.ogg', "your/path/to/plopp.mp3");
</script>

Now you can reach the initialized audio element whereever you like with simple event calls like

onclick="clicksound.playclip()"

onmouseover="plopsound.playclip()"

Hope this could be help!

For me, it had nothing to do with the code that I was using. For Azure we had to go into the settings of the App Service, on the side menu the entry "CORS". There I had to add the domain that I was requesting stuff from. Once I had that in, everything was magic.

For InstallShield MSI based projects I have found the following to work:

setup.exe /s /x /b"C:\FolderInWhichMSIWillBeExtracted" /v"/qn"

This command will lead to an extracted MSI in a directory you can freely specify and a silently failed uninstall of the product.

The command line basically tells the setup.exe to attempt to uninstall the product (/x) and do so silently (/s). While doing that it should extract the MSI to a specific location (/b).

The /v command passes arguments to Windows Installer, in this case the /qn argument. The /qn argument disables any GUI output of the installer.

You will want to use a CONVERT() statement.

Try the following;

SELECT CONVERT(VARCHAR(10), SA.[RequestStartDate], 103) as 'Service Start Date', CONVERT(VARCHAR(10), SA.[RequestEndDate], 103) as 'Service End Date', FROM (......) SA WHERE.....

See MSDN Cast and Convert for more information.

I implemented a pinch zoom for my TextView, using this tutorial. The resulting code is this:

private GestureDetector gestureDetector;
private View.OnTouchListener gestureListener;

and in onCreate():

    // Zoom handlers
    gestureDetector = new GestureDetector(new MyGestureDetector());
    gestureListener = new View.OnTouchListener() {

        // We can be in one of these 2 states
        static final int NONE = 0;
        static final int ZOOM = 1;
        int mode = NONE;

        static final int MIN_FONT_SIZE = 10;
        static final int MAX_FONT_SIZE = 50;

        float oldDist = 1f;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            TextView textView = (TextView) findViewById(R.id.text);

            switch (event.getAction() & MotionEvent.ACTION_MASK) {
                case MotionEvent.ACTION_POINTER_DOWN:
                    oldDist = spacing(event);
                    Log.d(TAG, "oldDist=" + oldDist);
                    if (oldDist > 10f) {
                       mode = ZOOM;
                       Log.d(TAG, "mode=ZOOM" );
                    }
                    break;
                case MotionEvent.ACTION_POINTER_UP:
                    mode = NONE;
                    break;
                case MotionEvent.ACTION_MOVE:
                    if (mode == ZOOM) {
                        float newDist = spacing(event);
                        // If you want to tweak font scaling, this is the place to go.
                        if (newDist > 10f) {
                            float scale = newDist / oldDist;

                            if (scale > 1) {
                                scale = 1.1f;
                            } else if (scale < 1) {
                                scale = 0.95f;
                            }

                            float currentSize = textView.getTextSize() * scale;
                            if ((currentSize < MAX_FONT_SIZE && currentSize > MIN_FONT_SIZE)
                                    ||(currentSize >= MAX_FONT_SIZE && scale < 1)
                                    || (currentSize <= MIN_FONT_SIZE && scale > 1)) {
                                textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, currentSize);
                            }
                        }
                    }
                    break;
                }
            return false;
        }

Magic constants 1.1 and 0.95 were chosen empirically (using scale variable for this purpose made my TextView behave kind of weird).

If I understand your question correctly, you're asking if you can call multiple constructors in C++?

If that's what you're looking for, then no - that is not possible.

You certainly can have multiple constructors, each with unique argument signatures, and then call the one you want when you instantiate a new object.

You can even have one constructor with defaulted arguments on the end.

But you may not have multiple constructors, and then call each of them separately.

Most of previous answers are correct. Here is one more way of converting column number to excel columns. solution is rather simple if we think about this as a base conversion. Simply, convert the column number to base 26 since there is 26 letters only. Here is how you can do this:

steps:

• set the column as a quotient

• subtract one from quotient variable (from previous step) because we need to end up on ascii table with 97 being a.

• divide by 26 and get the remainder.

• add +97 to remainder and convert to char (since 97 is "a" in ASCII table)
• quotient becomes the new quotient/ 26 (since we might go over 26 column)
• continue to do this until quotient is greater than 0 and then return the result

here is the code that does this :)

def convert_num_to_column(column_num):
    result = ""
    quotient = column_num
    remainder = 0
    while (quotient >0):
        quotient = quotient -1
        remainder = quotient%26
        result = chr(int(remainder)+97)+result
        quotient = int(quotient/26)
    return result

print("--",convert_num_to_column(1).upper())

With PHP

echo urlencode("http://www.image.com/?username=unknown&password=unknown");

Result

http%3A%2F%2Fwww.image.com%2F%3Fusername%3Dunknown%26password%3Dunknown

With Javascript:

var myUrl = "http://www.image.com/?username=unknown&password=unknown";
var encodedURL= "http://www.foobar.com/foo?imageurl=" + encodeURIComponent(myUrl);

By default, Sublime Text set 'UTF8 without BOM', but that wasn't specified.

The only specicified things is 'UTF8 with BOM'.

Hope this help :)

May be I am late to answer this, but what solved my problem was to install the mysql-server

sudo apt-get install mysql-server

after spending more than 5 hours I found this solution which helped me to proceed. I hope this would help someone if the top answers won't help them

When you start playing around with custom request headers you will get a CORS preflight. This is a request that uses the HTTP OPTIONS verb and includes several headers, one of which being Access-Control-Request-Headers listing the headers the client wants to include in the request.

You need to reply to that CORS preflight with the appropriate CORS headers to make this work. One of which is indeed Access-Control-Allow-Headers. That header needs to contain the same values the Access-Control-Request-Headers header contained (or more).

https://fetch.spec.whatwg.org/#http-cors-protocol explains this setup in more detail.

You can also access specific columns and values in each list element with [ and [[. Here are a couple of examples. First, we can access only the first column of each data frame in the list with lapply(ldf, "[", 1), where 1 signifies the column number.

ldf <- list(d1 = d1, d2 = d2)  ## create a named list of your data frames
lapply(ldf, "[", 1)
# $d1
#   y1
# 1  1
# 2  2
# 3  3
#
# $d2
#   y1
# 1  3
# 2  2
# 3  1

Similarly, we can access the first value in the second column with

lapply(ldf, "[", 1, 2)
# $d1
# [1] 4
# 
# $d2
# [1] 6

Then we can also access the column values directly, as a vector, with [[

lapply(ldf, "[[", 1)
# $d1
# [1] 1 2 3
#
# $d2
# [1] 3 2 1

If it's acceptible to simply publish your modules preinstalled in node_modules alongside your other files, you can do it like this:

// ./node_modules/foo/package.json
{ 
  "name":"foo",
  "version":"0.0.1",
  "main":"index.js"
}

// ./package.json
...
"dependencies": {
  "foo":"0.0.1",
  "bar":"*"
}

// ./app.js
var foo = require('foo');

You may also want to store your module on git and tell your parent package.json to install the dependency from git: https://npmjs.org/doc/json.html#Git-URLs-as-Dependencies

Check this out:

SELECT TABLE_SCHEMA ,
       TABLE_NAME ,
       COLUMN_NAME ,
       ORDINAL_POSITION ,
       COLUMN_DEFAULT ,
       DATA_TYPE ,
       CHARACTER_MAXIMUM_LENGTH ,
       NUMERIC_PRECISION ,
       NUMERIC_PRECISION_RADIX ,
       NUMERIC_SCALE ,
       DATETIME_PRECISION
FROM   INFORMATION_SCHEMA.COLUMNS
where TABLE_SCHEMA in ('dbo','meta')
and table_name in (select name from sys.tables)
order by TABLE_SCHEMA ,       TABLE_NAME ,ORDINAL_POSITION

I know this was already answered as to what the actual problem is, however I want to offer a simple workaround.

I wanted to use the get_results() method however I didn't have the driver, and I'm not somewhere I can get that added. So, before I called

$stmt->bind_results($var1,$var2,$var3,$var4...etc);

I created an empty array, and then just bound the results as keys in that array:

$result = array();
$stmt->bind_results($result['var1'],$result['var2'],$result['var3'],$result['var4']...etc);

so that those results could easily be passed into methods or cast to an object for further use.

Hope this helps anyone who's looking to do something similar.

The only other thing I would add is to make it a tad more flexible. Most times I'll have a trivial java file I want to run like - Main.java, Simple.java, Example.java, or Playground.java (you get the idea).

I use the following to strike off a javac and corresponding java.

@echo off
javac %~n1.java
java %~n1

The %~n1 gets the filename (sans extension) of the first argument passed to the batch file. So this way I can run it using tab completion and not have to worry about it working with either the .class or .java extension.

So both of the following will have the same result:

run.bat Main.class
and
run.bat Main.java

Doesn't 100% answer the original posters question, but I think it is a good next step/evolution for simple javac/java programs.

I have gone through array of solutions and this is what I found to have worked great for me.

In my case I needed to send a post request with some credentials. Small overhead was to add jquery inside the script. But was worth it.

var printPDF = function () {
        //prevent double sending
        var sendz = {};
        sendz.action = "Print";
        sendz.url = "api/Print";
        jQuery('<form action="' + sendz.url + '" method="POST">' +
            '<input type="hidden" name="action" value="Print" />'+
            '<input type="hidden" name="userID" value="'+$scope.user.userID+'" />'+
            '<input type="hidden" name="ApiKey" value="' + $scope.user.ApiKey+'" />'+
            '</form>').appendTo('body').submit().remove();

    }

Here is My 2 cents:

Have you tried: https://github.com/hackiftekhar/IQKeyboardManager

Extremely easy to install Swift or Objective-C.

Here how it works:

IQKeyboardManager (Swift):- IQKeyboardManagerSwift is available through CocoaPods, to install it simply add the following line to your Podfile: (#236)

pod 'IQKeyboardManagerSwift'

In AppDelegate.swift, just import IQKeyboardManagerSwift framework and enable IQKeyboardManager.

import IQKeyboardManagerSwift

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    IQKeyboardManager.sharedManager().enable = true
    // For Swift 4, use this instead
    // IQKeyboardManager.shared.enable = true


    return true
    }
}

And that is all. Easy!

if (strcmp("hello", "hello") = 0)

Is trying to assign 0 to function return value which isn't lvalue.

Function return values are not lvalue (no storage for it), so any attempt to assign value to something that is not lvalue result in error.

Best practice to avoid such mistakes in if conditions is to use constant value on left side of comparison, so even if you use "=" instead "==", constant being not lvalue will immediately give error and avoid accidental value assignment and causing false positive if condition.

You can do this with transition events, so you build two CSS classes for the transition, one holding the animation other, holding the display none state. And you switch them after the animation is ended? In my case I can display the divs again if I press a button, and remove both classes.

Try the snippet below...

$(document).ready(function() {_x000D_
  // Assign transition event_x000D_
  $("table").on("animationend webkitAnimationEnd", ".visibility_switch_off", function(event) {_x000D_
    // We check if this is the same animation we want_x000D_
    if (event.originalEvent.animationName == "col_hide_anim") {_x000D_
      // After the animation we assign this new class that basically hides the elements._x000D_
      $(this).addClass("animation-helper-display-none");_x000D_
    }_x000D_
_x000D_
  });_x000D_
_x000D_
  $("button").click(function(event) {_x000D_

      // We switch the animation class in a toggle fashion..._x000D_
      // and we know in that after the animation end, there_x000D_
      // is will the animation-helper-display-none extra_x000D_
      // class, that we nee to remove, when we want to_x000D_
      // show the elements again, depending on the toggle_x000D_
      // state, so we create a relation between them._x000D_
      if ($(this).is(".animation-helper-display-none")) {_x000D_
        // I'm toggling and there is already the above class, then_x000D_

• Hashtable and ConcurrentHashMap do not allow null keys or null values.

• Collections.synchronizedMap(Map) synchronizes all operations (get, put, size, etc).

• ConcurrentHashMap supports full concurrency of retrievals, and adjustable expected concurrency for updates.

As usual, there are concurrency--overhead--speed tradeoffs involved. You really need to consider the detailed concurrency requirements of your application to make a decision, and then test your code to see if it's good enough.

If you're inserting text content in your document in a location where text content is expected¹, you typically only need to escape the same characters as you would in XML. Inside of an element, this just includes the entity escape ampersand & and the element delimiter less-than and greater-than signs < >:

& becomes &
< becomes &lt;
> becomes &gt;

Inside of attribute values you must also escape the quote character you're using:

" becomes "
' becomes '

In some cases it may be safe to skip escaping some of these characters, but I encourage you to escape all five in all cases to reduce the chance of making a mistake.

If your document encoding does not support all of the characters that you're using, such as if you're trying to use emoji in an ASCII-encoded document, you also need to escape those. Most documents these days are encoded using the fully Unicode-supporting UTF-8 encoding where this won't be necessary.

In general, you should not escape spaces as  .   is not a normal space, it's a non-breaking space. You can use these instead of normal spaces to prevent a line break from being inserted between two words, or to insert          extra        space       without it being automatically collapsed, but this is usually a rare case. Don't do this unless you have a design constraint that requires it.

¹ By "a location where text content is expected", I mean inside of an element or quoted attribute value where normal parsing rules apply. For example: <p>HERE</p> or <p title="HERE">...</p>. What I wrote above does not apply to content that has special parsing rules or meaning, such as inside of a script or style tag, or as an element or attribute name. For example: <NOT-HERE>...</NOT-HERE>, <script>NOT-HERE</script>, <style>NOT-HERE</style>, or <p NOT-HERE="...">...</p>.

In these contexts, the rules are more complicated and it's much easier to introduce a security vulnerability. I strongly discourage you from ever inserting dynamic content in any of these locations. I have seen teams of competent security-aware developers introduce vulnerabilities by assuming that they had encoded these values correctly, but missing an edge case. There's usually a safer alternative, such as putting the dynamic value in an attribute and then handling it with JavaScript.

If you must, please read the Open Web Application Security Project's XSS Prevention Rules to help understand some of the concerns you will need to keep in mind.

You can do that simple with Files.size(new File(filename).toPath()).

What you are saying is in conflict with what it says in the MSDN library at this location:

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractserializer.aspx

I don't see any mention of the SP1 feature you mention.

Remember that window is the global namespace. These two lines attempt to declare the same variable:

window.APP = { ... }
const APP = window.APP

The second definition is not allowed in strict mode (enabled with 'use strict' at the top of your file).

To fix the problem, simply remove the const APP = declaration. The variable will still be accessible, as it belongs to the global namespace.

Unfortunately, in a cross platform, cross compiler environment, there is no single reliable method to do this purely at compile time.

• Both _WIN32 and _WIN64 can sometimes both be undefined, if the project settings are flawed or corrupted (particularly on Visual Studio 2008 SP1).
• A project labelled "Win32" could be set to 64-bit, due to a project configuration error.
• On Visual Studio 2008 SP1, sometimes the intellisense does not grey out the correct parts of the code, according to the current #define. This makes it difficult to see exactly which #define is being used at compile time.

Therefore, the only reliable method is to combine 3 simple checks:

• 1) Compile time setting, and;
• 2) Runtime check, and;
• 3) Robust compile time checking.

Simple check 1/3: Compile time setting

Choose any method to set the required #define variable. I suggest the method from @JaredPar:

// Check windows
#if _WIN32 || _WIN64
   #if _WIN64
     #define ENV64BIT
  #else
    #define ENV32BIT
  #endif
#endif

// Check GCC
#if __GNUC__
  #if __x86_64__ || __ppc64__
    #define ENV64BIT
  #else
    #define ENV32BIT
  #endif
#endif

Simple check 2/3: Runtime check

In main(), double check to see if sizeof() makes sense:

#if defined(ENV64BIT)
    if (sizeof(void*) != 8)
    {
        wprintf(L"ENV64BIT: Error: pointer should be 8 bytes. Exiting.");
        exit(0);
    }
    wprintf(L"Diagnostics: we are running in 64-bit mode.\n");
#elif defined (ENV32BIT)
    if (sizeof(void*) != 4)
    {
        wprintf(L"ENV32BIT: Error: pointer should be 4 bytes. Exiting.");
        exit(0);
    }
    wprintf(L"Diagnostics: we are running in 32-bit mode.\n");
#else
    #error "Must define either ENV32BIT or ENV64BIT".
#endif

Simple check 3/3: Robust compile time checking

The general rule is "every #define must end in a #else which generates an error".

#if defined(ENV64BIT)
    // 64-bit code here.
#elif defined (ENV32BIT)
    // 32-bit code here.
#else
    // INCREASE ROBUSTNESS. ALWAYS THROW AN ERROR ON THE ELSE.
    // - What if I made a typo and checked for ENV6BIT instead of ENV64BIT?
    // - What if both ENV64BIT and ENV32BIT are not defined?
    // - What if project is corrupted, and _WIN64 and _WIN32 are not defined?
    // - What if I didn't include the required header file?
    // - What if I checked for _WIN32 first instead of second?
    //   (in Windows, both are defined in 64-bit, so this will break codebase)
    // - What if the code has just been ported to a different OS?
    // - What if there is an unknown unknown, not mentioned in this list so far?
    // I'm only human, and the mistakes above would break the *entire* codebase.
    #error "Must define either ENV32BIT or ENV64BIT"
#endif

Update 2017-01-17

Comment from @AI.G:

4 years later (don't know if it was possible before) you can convert the run-time check to compile-time one using static assert: static_assert(sizeof(void*) == 4);. Now it's all done at compile time :)

Appendix A

Incidentially, the rules above can be adapted to make your entire codebase more reliable:

• Every if() statement ends in an "else" which generates a warning or error.
• Every switch() statement ends in a "default:" which generates a warning or error.

The reason why this works well is that it forces you to think of every single case in advance, and not rely on (sometimes flawed) logic in the "else" part to execute the correct code.

I used this technique (among many others) to write a 30,000 line project that worked flawlessly from the day it was first deployed into production (that was 12 months ago).

I thought I'd toss in the boost solution as well:

#include <boost/algorithm/string/replace.hpp>

// in place
std::string in_place = "blah#blah";
boost::replace_all(in_place, "#", "@");

// copy
const std::string input = "blah#blah";
std::string output = boost::replace_all_copy(input, "#", "@");

If a module was installed with the global (-g) flag, you can get the parent location by running:

npm get prefix

or

npm ls -g --depth=0

which will print the location along with the list of installed modules.

Create the below function

Alter FUNCTION InitialCap(@String VARCHAR(8000))
                  RETURNS VARCHAR(8000)
                 AS
 BEGIN 

                   DECLARE @Position INT;

SELECT @String   = STUFF(LOWER(@String),1,1,UPPER(LEFT(@String,1))) COLLATE Latin1_General_Bin,
                    @Position = PATINDEX('%[^A-Za-z''][a-z]%',@String COLLATE Latin1_General_Bin);

                    WHILE @Position > 0
                    SELECT @String   = STUFF(@String,@Position,2,UPPER(SUBSTRING(@String,@Position,2))) COLLATE Latin1_General_Bin,
                    @Position = PATINDEX('%[^A-Za-z''][a-z]%',@String COLLATE Latin1_General_Bin);

                     RETURN @String;
  END ;

Then call it like

select dbo.InitialCap(columnname) from yourtable

Draemon is correct. You can also declare m as taking varargs:

void m(String... strs) {
    // strs is seen as a normal String[] inside the method
}

m("blah", "hey", "yo"); // no [] or {} needed; each string is a separate arg here

Foreword

There are several definitions of objects, that are not real. The general term is test double. This term encompasses: dummy, fake, stub, mock.

Reference

According to Martin Fowler's article:

• Dummy objects are passed around but never actually used. Usually they are just used to fill parameter lists.
• Fake objects actually have working implementations, but usually take some shortcut which makes them not suitable for production (an in memory database is a good example).
• Stubs provide canned answers to calls made during the test, usually not responding at all to anything outside what's programmed in for the test. Stubs may also record information about calls, such as an email gateway stub that remembers the messages it 'sent', or maybe only how many messages it 'sent'.
• Mocks are what we are talking about here: objects pre-programmed with expectations which form a specification of the calls they are expected to receive.

Style

Mocks vs Stubs = Behavioral testing vs State testing

Principle

According to the principle of Test only one thing per test, there may be several stubs in one test, but generally there is only one mock.

Lifecycle

Test lifecycle with stubs:

1. Setup - Prepare object that is being tested and its stubs collaborators.
2. Exercise - Test the functionality.
3. Verify state - Use asserts to check object's state.
4. Teardown - Clean up resources.

Test lifecycle with mocks:

1. Setup data - Prepare object that is being tested.
2. Setup expectations - Prepare expectations in mock that is being used by primary object.
3. Exercise - Test the functionality.
4. Verify expectations - Verify that correct methods has been invoked in mock.
5. Verify state - Use asserts to check object's state.
6. Teardown - Clean up resources.

Summary

Both mocks and stubs testing give an answer for the question: What is the result?

Testing with mocks are also interested in: How the result has been achieved?

Just do a require('./yourfile.js');

Declare all the variables that you want outside access as global variables. So instead of

var a = "hello" it will be

GLOBAL.a="hello" or just

a = "hello"

This is obviously bad. You don't want to be polluting the global scope. Instead the suggest method is to export your functions/variables.

If you want the MVC pattern take a look at Geddy.

Consider the following:

1. Variables are pointers to values in memory.
2. Reassigning a variable merely points that pointer at a new value.
3. Reassigning a variable will never affect other variables that were pointing at that same object

So, forget about "pass by reference/value" don't get hung up on "pass by reference/value" because:

1. The terms are only used to describe the behavior of a language, not necessarily the actual underlying implementation. As a result of this abstraction, critical details that are essential for a decent explanation are lost, which inevitably leads to the current situation where a single term doesn't adequately describe the actual behavior and supplementary info has to be provided
2. These concepts were not originally defined with the intent of describing javascript in particular and so I don't feel compelled to use them when they only add to the confusion.

To answer your question: pointers are passed.

// code
var obj = {
    name: 'Fred',
    num: 1
};

// illustration
               'Fred'
              /
             /
(obj) ---- {}
             \
              \
               1

// code
obj.name = 'George';


// illustration
                 'Fred'


(obj) ---- {} ----- 'George'
             \
              \
               1

// code
obj = {};

// illustration
                 'Fred'


(obj)      {} ----- 'George'
  |          \
  |           \
 { }            1

// code
var obj = {
    text: 'Hello world!'
};

/* function parameters get their own pointer to 
 * the arguments that are passed in, just like any other variable */
someFunc(obj);


// illustration
(caller scope)        (someFunc scope)
           \             /
            \           /
             \         /
              \       /
               \     /
                 { }
                  |
                  |
                  |
            'Hello world'

Some final comments:

• It's tempting to think that primitives are enforced by special rules while objects are not, but primitives are simply the end of the pointer chain.
• As a final example, consider why a common attempt to clear an array doesn't work as expected.

var a = [1,2];
var b = a;

a = [];
console.log(b); // [1,2]
// doesn't work because `b` is still pointing at the original array

This is a very common misconception. There is no live HTML5 video support (except for HLS on iOS and Mac Safari). You may be able to 'hack' it using a webm container, but I would not expect that to be universally supported. What you are looking for is included in the Media Source Extensions, where you can feed the fragments to the browser one at a time. but you will need to write some client side javascript.

let utcTime = "2017-02-02 08:00:13.567";
var offset = moment().utcOffset();
var localText = moment.utc(utcTime).utcOffset(offset).format("L LT");

I use the following steps to solve the problem:

First, Make sure

“Run this program in compatibality mode for: Windows XP (Service Pack 3)” and “Run this program as an administrator” are ENABLED.

Run in Command Prompt

C:\Users\{yourusernamehere}\Documents\Downloads\netbeans-6.5-ml-windows.exe –-javahome "C:\Program Files (x86)\Java\jdk1.6.0_18"

Without For loop:

Dim newColumn As New Data.DataColumn("Foo", GetType(System.String))     
newColumn.DefaultValue = "Your DropDownList value" 
table.Columns.Add(newColumn) 

C#:

System.Data.DataColumn newColumn = new System.Data.DataColumn("Foo", typeof(System.String));
newColumn.DefaultValue = "Your DropDownList value";
table.Columns.Add(newColumn);

If the formula already exists in a cell you can fill it down as follows:

• Select the cell containing the formula and press CTRL+SHIFT+DOWN to select the rest of the column (CTRL+SHIFT+END to select up to the last row where there is data)
• Fill down by pressing CTRL+D
• Use CTRL+UP to return up

On Mac, use CMD instead of CTRL.

An alternative if the formula is in the first cell of a column:

• Select the entire column by clicking the column header or selecting any cell in the column and pressing CTRL+SPACE
• Fill down by pressing CTRL+D

In your svn\repos\YourRepo\conf folder you will find two files, authz and passwd. These are the two you need to adjust.

In the passwd file you need to add some usernames and passwords. I assume you have already done this since you have people using it:

[users]
User1=password1
User2=password2

Then you want to assign permissions accordingly with the authz file:

Create the conceptual groups you want, and add people to it:

[groups]
allaccess = user1
someaccess = user2

Then choose what access they have from both the permissions and project level.

So let's give our "all access" guys all access from the root:

[/]
@allaccess = rw

But only give our "some access" guys read-only access to some lower level project:

[/someproject]
@someaccess = r

You will also find some simple documentation in the authz and passwd files.

I thought it would be:

byte b = (byte)255;
int i = b &255;

If you need to get width 100% of PDF file and auto height you can use 'getImageProperties' property of html2canvas library

html2canvas(input)
      .then((canvas) => {
        const imgData = canvas.toDataURL('image/png');
        const pdf = new jsPDF({
          orientation: 'landscape',
        });
        const imgProps= pdf.getImageProperties(imgData);
        const pdfWidth = pdf.internal.pageSize.getWidth();
        const pdfHeight = (imgProps.height * pdfWidth) / imgProps.width;
        pdf.addImage(imgData, 'PNG', 0, 0, pdfWidth, pdfHeight);
        pdf.save('download.pdf');
      });

You haven't mentioned the DBMS. Assuming you are using MS SQL-Server, I've found a T-SQL Error message that is self-explanatory:

"An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference"

http://www.sql-server-performance.com/

And an example that it is possible in a subquery.

Show all customers and smallest order for those who have 5 or more orders (and NULL for others):

SELECT a.lastname
     , a.firstname
     , ( SELECT MIN( o.amount )
         FROM orders o
         WHERE a.customerid = o.customerid
           AND COUNT( a.customerid ) >= 5
        )
        AS smallestOrderAmount
FROM account a
GROUP BY a.customerid
       , a.lastname
       , a.firstname ;

UPDATE.

The above runs in both SQL-Server and MySQL but it doesn't return the result I expected. The next one is more close. I guess it has to do with that the field customerid, GROUPed BY and used in the query-subquery join is in the first case PRIMARY KEY of the outer table and in the second case it's not.

Show all customer ids and number of orders for those who have 5 or more orders (and NULL for others):

SELECT o.customerid
     , ( SELECT COUNT( o.customerid )
         FROM account a
         WHERE a.customerid = o.customerid
           AND COUNT( o.customerid ) >= 5
        )
        AS cnt
FROM orders o
GROUP BY o.customerid ;

See the UIScreen Reference: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIScreen_Class/Reference/UIScreen.html

if([[UIScreen mainScreen] respondsToSelector:NSSelectorFromString(@"scale")])
{
    if ([[UIScreen mainScreen] scale] < 1.1)
        NSLog(@"Standard Resolution Device");

    if ([[UIScreen mainScreen] scale] > 1.9)
        NSLog(@"High Resolution Device");
}

I just realized that the hist documentation is explicit about what to do when you already have an np.histogram

counts, bins = np.histogram(data)
plt.hist(bins[:-1], bins, weights=counts)

The important part here is that your counts are simply the weights. If you do it like that, you don't need the bar function anymore

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.

This question is similar to this question.

You say that you have profiled the application. Have you profiled the ORM too? There is an EF profiler from Ayende that will highlight where you can optimise your EF code. You can find it here:

http://efprof.com/

Remember that you can use a traditional SQL approach alongside your ORM if you need to to gain performance.

If there a faster/better ORM? Depending on your object/data model, you could consider using a one of the micro-ORMs, such as Dapper, Massive or PetaPoco.

The Dapper site publishes some comparitive benchmarks that will give you an idea how they compare to other ORMs. But it's worth noting that the micro-ORMs do not support the rich feature set of the full ORMs like EF and NH.

You may want to take a look at RavenDB. This is a non-relational database (from Ayende again) that lets you store POCOs directly with no mapping needed. RavenDB is optimised for reads and makes the developers life a whole lot easier by removing need to manipulate schema and to map your objects to that schema. However, be aware that this is a significantly different approach to using an ORM approach and these are outlined in the product's site.

The bracket stuff (e.g., [[ $a -gt $b ]] or (( $a > $b )) ) isn't enough if you want to use float numbers as well; it would report a syntax error. If you want to compare float numbers or float number to integer, you can use (( $(bc <<< "...") )).

For example,

a=2.00
b=1

if (( $(bc <<<"$a > $b") )); then 
    echo "a is greater than b"
else
    echo "a is not greater than b"
fi

You can include more than one comparison in the if statement. For example,

a=2.
b=1
c=1.0000

if (( $(bc <<<"$b == $c && $b < $a") )); then 
    echo "b is equal to c but less than a"
else
    echo "b is either not equal to c and/or not less than a"
fi

That's helpful if you want to check if a numeric variable (integer or not) is within a numeric range.

help('modules') should do it for you.

• A leading slash tells the browser to start at the root directory.
• If you don't have the leading slash, you're referencing from the current directory.
• If you add two dots before the leading slash, it means you're referencing the parent of the current directory.

Take the following folder structure

notice:

• the ROOT checkmark is green,
• the second checkmark is orange,
• the third checkmark is purple,
• the forth checkmark is yellow

Now in the index.html.en file you'll want to put the following markup

<p>
    <span>src="check_mark.png"</span>
    <img src="check_mark.png" />
    <span>I'm purple because I'm referenced from this current directory</span>
</p>

<p>
    <span>src="/check_mark.png"</span>
    <img src="/check_mark.png" />
    <span>I'm green because I'm referenced from the ROOT directory</span>
</p>

<p>
    <span>src="subfolder/check_mark.png"</span>
    <img src="subfolder/check_mark.png" />
    <span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>

<p>
    <span>src="/subfolder/check_mark.png"</span>
    <img src="/subfolder/check_mark.png" />
    <span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>

<p>
    <span>src="../subfolder/check_mark.png"</span>
    <img src="../subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>

<p>
    <span>src="subfolder/subfolder/check_mark.png"</span>
    <img src="subfolder/subfolder/check_mark.png" />
    <span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>

<p>
    <span>src="/subfolder/subfolder/check_mark.png"</span>
    <img src="/subfolder/subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>

Now if you load up the index.html.en file located in the second subfolder
http://example.com/subfolder/subfolder/

This will be your output

Following will display 25 records excluding first 50 records works in SQL Server 2012.

SELECT * FROM MyTable ORDER BY ID OFFSET 50 ROWS FETCH NEXT 25 ROWS ONLY;

you can replace ID as your requirement

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

Addressing Steven's comment to Sam Dufel's answer

Thanks, sounds like that's the way to go. But I just realized that I only want the optional whitespace characters if they follow a newline. So for example, "c\n ats" or "ca\n ts" should match. But wouldn't want "c ats" to match if there is no newline. Any ideas on how that might be done?

This should do the trick:

/c(?:\n\s*)?a(?:\n\s*)?t(?:\n\s*)?s/

See this page for all the different variations of 'cats' that this matches.

You can also solve this using conditionals, but they are not supported in the javascript flavor of regex.

Yes, you can select the data, calculate the difference, and insert all values in the other table:

insert into #temp2 (Difference)
select previous - Present
from #TEMP1

Connection in APPConfig

<connectionStrings>
  <add name="ConnectionString" connectionString="Data Source=192.168.1.25;Initial Catalog=Login;Persist Security Info=True;User ID=sa;Password=example.com"   providerName="System.Data.SqlClient" />
</connectionStrings>

In Class.Cs

public string ConnectionString
{
    get
    {
        return System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ToString();
    }
}

Disconnect your device from the computer.

Go into developer settings.

Turn off developer settings.

Turn on developer settings.

Enable USB Debugging (and whatever other settings you enabled beforehand)

Reconnect your device to the computer.

Try again.

Worked for me so hope it works for you!

If you're using Oracle, then a feature called analytics will do the trick. It looks like this:

select id, age, count(*) over (partition by age) from students;

If you aren't using Oracle, then you'll need to join back to the counts:

select a.id, a.age, b.age_count
  from students a
  join (select age, count(*) as age_count
          from students
         group by age) b
    on a.age = b.age

After spending a good bit of time today trying to wrap my brain around the (significant but powerful) paradigm shift between old ways of processing web form data and how it is done with WebAPI, I thought I'd add my 2 cents to this discussion.

What I wanted to do (which is pretty common for web form processing of a POST) is to be able to grab any of the form values I want, in any order. Say like you can do if you have your data in a System.Collections.Specialized.NameValueCollection. But turns out, in WebAPI, the data from a POST comes back at you as a stream. So you can't directly do that.

But there is a cool little class named FormDataCollection (in System.Net.Http.Formatting) and what it will let you do is iterate through your collection once.

So I wrote a simple utility method that will run through the FormDataCollection once and stick all the values into a NameValueCollection. Once this is done, you can jump all around the data to your hearts content.

So in my ApiController derived class, I have a post method like this:

    public void Post(FormDataCollection formData)
    {
        NameValueCollection valueMap = WebAPIUtils.Convert(formData);

        ... my code that uses the data in the NameValueCollection
    }

The Convert method in my static WebAPIUtils class looks like this:

    /// <summary>
    /// Copy the values contained in the given FormDataCollection into 
    /// a NameValueCollection instance.
    /// </summary>
    /// <param name="formDataCollection">The FormDataCollection instance. (required, but can be empty)</param>
    /// <returns>The NameValueCollection. Never returned null, but may be empty.</returns>
    public static NameValueCollection Convert(FormDataCollection formDataCollection)
    {
        Validate.IsNotNull("formDataCollection", formDataCollection);

        IEnumerator<KeyValuePair<string, string>> pairs = formDataCollection.GetEnumerator();

        NameValueCollection collection = new NameValueCollection();

        while (pairs.MoveNext())
        {
            KeyValuePair<string, string> pair = pairs.Current;

            collection.Add(pair.Key, pair.Value);
        }

        return collection;
     }

Hope this helps!

If you're using MySQL, then you can use insert ... on duplicate.

The problem you have with the SelectedValue is not converting into integer. This is the main problem so usinge the following code snippet will help you:

int selectedValue;
bool parseOK = Int32.TryParse(cmb.SelectedValue.ToString(), out selectedValue);

Similar to Olayinka's answer about the configuration file for ADT: I just had the same issue on IntelliJ's IdeaU v14.

I'm working through a tutorial that had me change the starting activity from MyActivity to MyListActivity (Which is a list of MyActivity). I started getting Permissions Denial.

After much trial, toil and pain: In .idea\workspace.xml:

...
<configuration default="false" name="MyApp" type="AndroidRunConfigurationType" factoryName="Android Application">
    <module name="MyApp" />
    <option name="ACTIVITY_CLASS" value="com.domain.MyApp.MyActivity" />
    ...
</configuration>
...

I changed the MyActivity to MyListActivity, reloaded the project and I'm off to a rolling start again.

Not sure which IDE you are using, but maybe your IDE is overriding or forcing a specific starting activity?

I ran into this in a Web App on Azure when attempting to connect to Blob Storage. The problem turned out to be that I had missed deploying a connection string for the blob storage so it was still pointing at the storage emulator. There must be some retry logic built into the client because I saw about 3 attempts. The /devstorageaccount1 here is a dead giveaway.

Fixed by properly setting the connection string in Azure.

I made a function to get a vector of queries and do a transaction, maybe someone will find out it useful:

function transaction ($con, $Q){
        mysqli_query($con, "START TRANSACTION");

        for ($i = 0; $i < count ($Q); $i++){
            if (!mysqli_query ($con, $Q[$i])){
                echo 'Error! Info: <' . mysqli_error ($con) . '> Query: <' . $Q[$i] . '>';
                break;
            }   
        }

        if ($i == count ($Q)){
            mysqli_query($con, "COMMIT");
            return 1;
        }
        else {
            mysqli_query($con, "ROLLBACK");
            return 0;
        }
    }

GnuPG can be used as cross-platform password manager, including GIT HTTPS credetials. Just use your GPG key-pair to encrypt/decrypt passwords(tokens...). To encrypt token(password) run:

gpg -e -o [PATH_TO_ENCRYPTED_TOKEN] -r "[GPG_KEY_USER_ID]"

type the token (or copy-paste it) then press Ctrl+D for ending input, or use file name with this token. Then make custom git credential helper: BASH file with name git-credential-[HELPER_LAST_NAME] (without SH extension):

#!/bin/bash
token=`gpg -d -r "[GPG_KEY_USER_ID]" [PATH_TO_ENCRYPTED_TOKEN] 2>/dev/null`
echo protocol=https
echo host=[YOUR_HOST]
echo username=[YOUR_USER_NAME]
echo password=$token

On MS-WINDOWS in GIT-BASH path names must use UNIX file separator - "/", just run in git-bash "echo $PATH"! Then put the helper into place as in $PATH. Then add and check the helper:

git config --global credential.helper [HELPER_LAST_NAME]
#then check it (password will be printed as plain text!!!):
git credential-[HELPER_LAST_NAME]

GnuPG can be used as password manager in Maven projects instead of Maven's password-encryption method. And so on.

I wrote this algorithm for similar kind of problem with DP, may it help

public class MinimumCoinProblem {

    private static void calculateMinumCoins(int[] array_Coins, int sum) {

        int[] array_best = new int[sum];

        for (int i = 0; i < sum; i++) {
            for (int j = 0; j < array_Coins.length; j++) {
                    if (array_Coins[j] <= i  && (array_best[i] == 0 || (array_best[i - array_Coins[j]] + 1) <= array_best[i])) {
                        array_best[i] = array_best[i - array_Coins[j]] + 1;
                    }
            }
        }
        System.err.println("The Value is" + array_best[14]);

    }


    public static void main(String[] args) {
        int[] sequence1 = {11, 9,1, 3, 5,2 ,20};
        int sum = 30;
        calculateMinumCoins(sequence1, sum);
    }

}

You can use the following script if you don't wish to use Wizard;

RESTORE DATABASE myDB
FROM  DISK = N'C:\BackupDB.bak' 
WITH  REPLACE,RECOVERY,  
MOVE N'HRNET' TO N'C:\MSSQL\Data\myDB.mdf',  
MOVE N'HRNET_LOG' TO N'C:\MSSQL\Data\myDB.ldf'

If you use Kotlin, the next one is a good solution:

myRef.addListenerForSingleValueEvent(object : ValueEventListener {
  override fun onDataChange(dataSnapshot: DataSnapshot) {
      val list = dataSnapshot.children.map { it.getValue(YourClass::class.java)!! }
      Log.d("TAG", "Value is: $list")
}

See tables from Python string formatting to select the proper format layout. In your case it's %.2E.

You need to copy the dependency you need for project. Having these in hand please clear all the <dependency> tag embedded into <dependencies> tag from POM.XML file in your project.

After saving the file you will not see Maven Dependencies in your Libraries. Then please paste those <dependency> you have copied earlier.

The required jars will be automatically downloaded by Maven, you can see that too in the generated Maven Dependencies Libraries after saving the file.

Thanks.

Try this, I've used it in a personal wiki-like app:

webView.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url.startsWith("foo://")) {
            // magic
            return true;
        }
        return false;
    }
});

Map default.aspx as HttpHandler route and redirect to CreateThings.aspx from within the HttpHandler.

<add verb="GET" path="default.aspx" type="RedirectHandler"/>

Make sure Default.aspx does not exists physically at your application root. If it exists physically the HttpHandler will not be given any chance to execute. Physical file overrides HttpHandler mapping.

Moreover you can re-use this for pages other than default.aspx.

<add verb="GET" path="index.aspx" type="RedirectHandler"/>

//RedirectHandler.cs in your App_Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

/// <summary>
/// Summary description for RedirectHandler
/// </summary>
public class RedirectHandler : IHttpHandler
{
    public RedirectHandler()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    #region IHttpHandler Members

    public bool IsReusable
    {
        get { return true; }
    }

    public void ProcessRequest(HttpContext context)
    {
        context.Response.Redirect("CreateThings.aspx");
        context.Response.End();
    }

    #endregion
}

The split work until 4000 chars depending on the characters that you are inserting. If you are inserting special characters it can fail. The only secure way is to declare a variable.

Performance-wise it's the same as a named method. The big problem is when you do the following:

MyButton.Click -= (o, i) => 
{ 
    //snip 
} 

It will probably try to remove a different lambda, leaving the original one there. So the lesson is that it's fine unless you also want to be able to remove the handler.

Seems to be quite efficient:

import datetime
day, month, year = '01/12/2011'.split('/')
datetime.datetime(int(year), int(month), int(day)).timestamp()

1.61 µs ± 120 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.

Are you sure, you want to do that? Even css and js files and images and ...?

OK, first check if mod_access in installed to apache, then add the following to your .htaccess:

Order Deny,Allow
Deny from all
Allow from 127.0.0.1

<Files /index.php>
    Order Allow,Deny
    Allow from all
</Files>

The first directive forbids access to any files except from localhost, because of Order Deny,Allow, Allow gets applied later, the second directive only affects index.php.

Caveat: No space after the comma in the Order line.

To allow access to files matching *.css or *.js use this directive:

<FilesMatch ".*\.(css|js)$">
    Order Allow,Deny
    Allow from all
</FilesMatch>

You cannot use directives for <Location> or <Directory> inside .htaccess files, though.

Your option would be to use <FilesMatch ".*\.php$"> around the first allow,deny group and then explicitely allow access to index.php.

Update for Apache 2.4: This answer is correct for Apache 2.2. In Apache 2.4 the access control paradigm has changed, and the correct syntax is to use Require all denied.

I know this is really old and most of the folks have already answered it right. Here are at least two ways you can find out the gradle version (not the gradle plugin version) by selecting one of the following on project tab on left:

1. Android > Gradle Scripts > gradle-wrapper.properties (Gradle Version) > distributionURL
2. Project > .gradle > x.y.z <--- this is your gradle version

Also, if your table has no ID column, or sorting by id doesn't return you the last row, you can always use sqlite schema native 'rowid' field.

SELECT column 
FROM table 
WHERE rowid = (SELECT MAX(rowid) FROM table);

Here is my implementation which uses hash table for the delimiter, which means it O(n) instead of O(n^2) (here is a link to the code):

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

#define DICT_LEN 256

int *create_delim_dict(char *delim)
{
    int *d = (int*)malloc(sizeof(int)*DICT_LEN);
    memset((void*)d, 0, sizeof(int)*DICT_LEN);

    int i;
    for(i=0; i< strlen(delim); i++) {
        d[delim[i]] = 1;
    }
    return d;
}



char *my_strtok(char *str, char *delim)
{

    static char *last, *to_free;
    int *deli_dict = create_delim_dict(delim);

    if(!deli_dict) {
        /*this check if we allocate and fail the second time with entering this function */
        if(to_free) {
            free(to_free);
        }
        return NULL;
    }

    if(str) {
        last = (char*)malloc(strlen(str)+1);
        if(!last) {
            free(deli_dict);
            return NULL;
        }
        to_free = last;
        strcpy(last, str);
    }

    while(deli_dict[*last] && *last != '\0') {
        last++;
    }
    str = last;
    if(*last == '\0') {
        free(deli_dict);
        free(to_free);
        deli_dict = NULL;
        to_free = NULL;
        return NULL;
    }
    while (*last != '\0' && !deli_dict[*last]) {
        last++;
    }

    *last = '\0';
    last++;

    free(deli_dict);
    return str;
}

int main()
{
    char * str = "- This, a sample string.";
    char *del = " ,.-";
    char *s = my_strtok(str, del);
    while(s) {
        printf("%s\n", s);
        s = my_strtok(NULL, del);
    }
    return 0;
}

3. gradle-wrapper.properties

   distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

My problem was solved by creating a Windows user without an accent or special characters and reinstalling android studio on that user. Another change is to change the environment variables:

Left Click in My Computer > Advanced System Settings> Advanced > Environment Variables

ANDROID_HOME = c:\my_sdk_path

ANDROID_SDK_ROOT = c:\my_sdk_path

JAVA_HOME = c:\program files\Java\yourJavaPath

• the default path of SDK is c:\users\youruser\AppData\LocalAndroid\sdk

Add in Path Variable the values:

1. %ANDROID_HOME%\platform-tools

2. %ANDROID_HOME%\tools

After changes, restart windows and try again!

You can use :

1. git stash to save your work
2. git checkout <your-branch>
3. git stash apply or git stash pop to load your last work

Git stash extremely useful when you want temporarily save undone or messy work, while you want to doing something on another branch.

git -stash documentation

You can either extend the Thread class or the Runnable class and provide parameters as you want. There are simple examples in the docs. I'll port them here:

 class PrimeThread extends Thread {
     long minPrime;
     PrimeThread(long minPrime) {
         this.minPrime = minPrime;
     }

     public void run() {
         // compute primes larger than minPrime
          . . .
     }
 }

 PrimeThread p = new PrimeThread(143);
 p.start();

 class PrimeRun implements Runnable {
     long minPrime;
     PrimeRun(long minPrime) {
         this.minPrime = minPrime;
     }

     public void run() {
         // compute primes larger than minPrime
          . . .
     }
 }


 PrimeRun p = new PrimeRun(143);
 new Thread(p).start();

Try clean project...

If it doesn't work... Then... Goto build.gradle in project section

Try downgrading the gradle version

From...

dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0'
}

To...

dependencies {
    classpath 'com.android.tools.build:gradle:1.2.0'
}

Then gradle.properties, add this

 org.gradle.jvmargs=-XX\:MaxHeapSize\=256m -Xmx256m

Sync it... Clean/Rebuild... It worked for me... So, I am sharing...

Check this out: http://qrdroid.com/web-masters.php

You can create a link in your web form, something like:

http://qrdroid.com/scan?q=http://www.your-site.com/your-form.php?code={CODE}

When somebody clicks that link, an app to scan the code will be opened. After the user scans the code, http://www.your-site.com/your-form.php?code={CODE} will be automatically called. You can then make your-form.php read the parameter code to prepopulate the field.

You can just read the data into a list and insert the new record where you want.

names = []
with open('names.txt', 'r+') as fd:
    for line in fd:
        names.append(line.split(' ')[-1].strip())

    names.insert(2, "Charlie") # element 2 will be 3. in your list
    fd.seek(0)
    fd.truncate()

    for i in xrange(len(names)):
        fd.write("%d. %s\n" %(i + 1, names[i]))

One way to implement deep copy is to add copy constructors to each associated class. A copy constructor takes an instance of 'this' as its single argument and copies all the values from it. Quite some work, but pretty straightforward and safe.

EDIT: note that you don't need to use accessor methods to read fields. You can access all fields directly because the source instance is always of the same type as the instance with the copy constructor. Obvious but might be overlooked.

Example:

public class Order {

    private long number;

    public Order() {
    }

    /**
     * Copy constructor
     */
    public Order(Order source) {
        number = source.number;
    }
}


public class Customer {

    private String name;
    private List<Order> orders = new ArrayList<Order>();

    public Customer() {
    }

    /**
     * Copy constructor
     */
    public Customer(Customer source) {
        name = source.name;
        for (Order sourceOrder : source.orders) {
            orders.add(new Order(sourceOrder));
        }
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Edit: Note that when using copy constructors you need to know the runtime type of the object you are copying. With the above approach you cannot easily copy a mixed list (you might be able to do it with some reflection code).

You should use the EndXXX of your async method to return the value. EndXXX should wait until there is a result using the IAsyncResult's WaitHandle and than return with the value.

Historically (we're talking the 1980s and early 1990s), there were some architectures in which this was true. The root issue is that integer comparison is inherently implemented via integer subtractions. This gives rise to the following cases.

Comparison     Subtraction
----------     -----------
A < B      --> A - B < 0
A = B      --> A - B = 0
A > B      --> A - B > 0

Now, when A < B the subtraction has to borrow a high-bit for the subtraction to be correct, just like you carry and borrow when adding and subtracting by hand. This "borrowed" bit was usually referred to as the carry bit and would be testable by a branch instruction. A second bit called the zero bit would be set if the subtraction were identically zero which implied equality.

There were usually at least two conditional branch instructions, one to branch on the carry bit and one on the zero bit.

Now, to get at the heart of the matter, let's expand the previous table to include the carry and zero bit results.

Comparison     Subtraction  Carry Bit  Zero Bit
----------     -----------  ---------  --------
A < B      --> A - B < 0    0          0
A = B      --> A - B = 0    1          1
A > B      --> A - B > 0    1          0

So, implementing a branch for A < B can be done in one instruction, because the carry bit is clear only in this case, , that is,

;; Implementation of "if (A < B) goto address;"
cmp  A, B          ;; compare A to B
bcz  address       ;; Branch if Carry is Zero to the new address

But, if we want to do a less-than-or-equal comparison, we need to do an additional check of the zero flag to catch the case of equality.

;; Implementation of "if (A <= B) goto address;"
cmp A, B           ;; compare A to B
bcz address        ;; branch if A < B
bzs address        ;; also, Branch if the Zero bit is Set

So, on some machines, using a "less than" comparison might save one machine instruction. This was relevant in the era of sub-megahertz processor speed and 1:1 CPU-to-memory speed ratios, but it is almost totally irrelevant today.

You could inspect the available apache2 modules:

$ ls /usr/lib/apache2/modules/

Or try to enable the php module, if you have the appropriate access:

$ a2enmod
Which module would you like to enable?
Your choices are: actions alias asis ...
... php5 proxy_ajp proxy_balancer proxy_connect ..

The task boils down to iterating over characters of the string and collecting them into a list. The most naïve solution would look like

result = []
for character in string:
    result.append(character)

Of course, it can be shortened to just

result = [character for character in string]

but there still are shorter solutions that do the same thing.

list constructor can be used to convert any iterable (iterators, lists, tuples, string etc.) to list.

>>> list('abc')
['a', 'b', 'c']

The big plus is that it works the same in both Python 2 and Python 3.

Also, starting from Python 3.5 (thanks to the awesome PEP 448) it's now possible to build a list from any iterable by unpacking it to an empty list literal:

>>> [*'abc']
['a', 'b', 'c']

This is neater, and in some cases more efficient than calling list constructor directly.

I'd advise against using map-based approaches, because map does not return a list in Python 3. See How to use filter, map, and reduce in Python 3.

This problem was caused by an orphaned SQL Login. I ran my favorite sp_fixusers script and the error was resolved. The suggestion above to look at the logs was a good one...and it led me to my answer.

First of all: you should always import mockito static, this way the code will be much more readable (and intuitive) - the code samples below require it to work:

import static org.mockito.Mockito.*;

In the verify() method you can pass the ArgumentCaptor to assure execution in the test and the ArgumentCaptor to evaluate the arguments:

ArgumentCaptor<MyExampleClass> argument = ArgumentCaptor.forClass(MyExampleClass.class);
verify(yourmock, atleast(2)).myMethod(argument.capture());

List<MyExampleClass> passedArguments = argument.getAllValues();

for (MyExampleClass data : passedArguments){
    //assertSometing ...
    System.out.println(data.getFoo());
}

The list of all passed arguments during your test is accessible via the argument.getAllValues() method.

The single (last called) argument's value is accessible via the argument.getValue() for further manipulation / checking or whatever you wish to do.

I am using Angular 4 with the 4.3 httpClient object. I modified an answer I found in Js' Technical Blog which creates a link object, uses it to do the download, then destroys it.

Client:

doDownload(id: number, contentType: string) {
    return this.http
        .get(this.downloadUrl + id.toString(), { headers: new HttpHeaders().append('Content-Type', contentType), responseType: 'blob', observe: 'body' })
}

downloadFile(id: number, contentType: string, filename:string)  {

    return this.doDownload(id, contentType).subscribe(  
        res => { 
            var url = window.URL.createObjectURL(res);
            var a = document.createElement('a');
            document.body.appendChild(a);
            a.setAttribute('style', 'display: none');
            a.href = url;
            a.download = filename;
            a.click();
            window.URL.revokeObjectURL(url);
            a.remove(); // remove the element
        }, error => {
            console.log('download error:', JSON.stringify(error));
        }, () => {
            console.log('Completed file download.')
        }); 

} 

The value of this.downloadUrl has been set previously to point to the api. I am using this to download attachments, so I know the id, contentType and filename: I am using an MVC api to return the file:

 [ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]
    public FileContentResult GetAttachment(Int32 attachmentID)
    { 
        Attachment AT = filerep.GetAttachment(attachmentID);            
        if (AT != null)
        {
            return new FileContentResult(AT.FileBytes, AT.ContentType);  
        }
        else
        { 
            return null;
        } 
    } 

The attachment class looks like this:

 public class Attachment
{  
    public Int32 AttachmentID { get; set; }
    public string FileName { get; set; }
    public byte[] FileBytes { get; set; }
    public string ContentType { get; set; } 
}

The filerep repository returns the file from the database.

Hope this helps someone :)

console.log() just takes whatever you pass to it and writes it to a console's log window. If you pass in an array, you'll be able to inspect the array's contents. Pass in an object, you can examine the object's attributes/methods. pass in a string, it'll log the string. Basically it's "document.write" but can intelligently take apart its arguments and write them out elsewhere.

It's useful to outputting occasional debugging information, but not particularly useful if you have a massive amount of debugging output.

To watch as a script's executing, you'd use a debugger instead, which allows you step through the code line-by-line. console.log's used when you need to display what some variable's contents were for later inspection, but do not want to interrupt execution.

Actually, the best way to solve this is... on the <object> tag, use:

pointer-events: none;

Note: Users which have the Ad Blocker plugin installed get a tab-like [Block] at the upper right corner upon hovering (the same as a flash banner gets). By settings this css, that'll go away as well.

Keep the labels from your original file like this:

df = read.table('data.txt', header = T)

If you have columns named x and y, you can address them like this:

df$x
df$y

If you'd like to actually delete the first row from a data.frame, you can use negative indices like this:

df = df[-1,]

If you'd like to delete a column from a data.frame, you can assign NULL to it:

df$x = NULL

Here are some simple examples of how to create and manipulate a data.frame in R:

# create a data.frame with 10 rows
> x = rnorm(10)
> y = runif(10)
> df = data.frame( x, y )

# write it to a file
> write.table( df, 'test.txt', row.names = F, quote = F )

# read a data.frame from a file: 
> read.table( df, 'test.txt', header = T )

I managed to get this working in Chrome and Firefox too by appending a link to the to document.

var link = document.createElement('a');
link.href = 'images.jpg';
link.download = 'Download.jpg';
document.body.appendChild(link);
link.click();
document.body.removeChild(link);

Use the Pattern#quote() method for escaping ||. Try:

final String[] tokens = myString.split(Pattern.quote("||"));

This is required because | is an alternation character and hence gains a special meaning when passed to split call (basically the argument to split is a regular expression in string form).

When adding "use strict";, the following cases will throw a SyntaxError before the script is executing:

• Paving the way for future ECMAScript versions, using one of the newly reserved keywords (in prevision for ECMAScript 6): implements, interface, let, package, private, protected, public, static, and yield.

• Declaring function in blocks

  if(a<b){ function f(){} }
  

• Octal syntax

  var n = 023;
  

• this point to the global object.

   function f() {
        "use strict";
        this.a = 1;
   };
   f(); 
  

• Declaring twice the same name for a property name in an object literal

   {a: 1, b: 3, a: 7} 
  

  This is no longer the case in ECMAScript 6 (bug 1041128).

• Declaring two function arguments with the same name function

  f(a, b, b){}
  

• Setting a value to an undeclared variable

  function f(x){
     "use strict";
     var a = 12;
     b = a + x*35; // error!
  }
  f();
  

• Using delete on a variable name delete myVariable;

• Using eval or arguments as variable or function argument name

  "use strict";
  arguments++;
  var obj = { set p(arguments) { } };
  try { } catch (arguments) { }
  function arguments() { }

As Mystere Man suggested, getting just a view first and then again making an ajax call again to get the json result is unnecessary in this case. that is 2 calls to the server. I think you can directly return an HTML table of Users in the first call.

We will do this in this way. We will have a strongly typed view which will return the markup of list of users to the browser and this data is being supplied by an action method which we will invoke from our browser using an http request.

Have a ViewModel for the User

public class UserViewModel
{
  public int UserID { set;get;}
  public string FirstName { set;get;}
   //add remaining properties as per your requirement

}

and in your controller have a method to get a list of Users

public class UserController : Controller
{

   [HttpGet]
   public ActionResult List()
   {
     List<UserViewModel> objList=UserService.GetUsers();  // this method should returns list of  Users
     return View("users",objList)        
   }
}

Assuming that UserService.GetUsers() method will return a List of UserViewModel object which represents the list of usres in your datasource (Tables)

and in your users.cshtml ( which is under Views/User folder),

 @model List<UserViewModel>

 <table>

 @foreach(UserViewModel objUser in Model)
 {
   <tr>
      <td>@objUser.UserId.ToString()</td>
      <td>@objUser.FirstName</td>
   </tr>
 }
 </table>

All Set now you can access the url like yourdomain/User/List and it will give you a list of users in an HTML table.

I believe this is what you're looking for. It automatically scaled the video to fit the container.

DEMO: http://jsfiddle.net/t8qhgxuy/

Video need to have height and width always set to 100% of the parent.

HTML:

<div class="one"> CONTENT OVER VIDEO
    <video class="video-background" no-controls autoplay src="https://dl.dropboxusercontent.com/u/8974822/cloud-troopers-video.mp4" poster="http://thumb.multicastmedia.com/thumbs/aid/w/h/t1351705158/1571585.jpg"></video>
</div>

<div class="two">
    <video class="video-background" no-controls autoplay src="https://dl.dropboxusercontent.com/u/8974822/cloud-troopers-video.mp4" poster="http://thumb.multicastmedia.com/thumbs/aid/w/h/t1351705158/1571585.jpg"></video> CONTENT OVER VIDEO
</div>

CSS:

body {
    overflow: scroll;
    padding:  60px 20px;
}

.one {
    width: 90%;
    height: 30vw;
    overflow: hidden;
    border: 15px solid red;
    margin-bottom: 40px;
    position: relative;
}

.two{
    width: 30%;
    height: 300px;
    overflow: hidden;
    border: 15px solid blue;
    position: relative;
}

.video-background { /* class name used in javascript too */
    width: 100%; /* width needs to be set to 100% */
    height: 100%; /* height needs to be set to 100% */
    position: absolute;
    left: 0;
    top: 0;
    z-index: -1;
}

JS:

function scaleToFill() {
    $('video.video-background').each(function(index, videoTag) {
       var $video = $(videoTag),
           videoRatio = videoTag.videoWidth / videoTag.videoHeight,
           tagRatio = $video.width() / $video.height(),
           val;

       if (videoRatio < tagRatio) {
           val = tagRatio / videoRatio * 1.02; <!-- size increased by 2% because value is not fine enough and sometimes leaves a couple of white pixels at the edges -->
       } else if (tagRatio < videoRatio) {
           val = videoRatio / tagRatio * 1.02;
       }

       $video.css('transform','scale(' + val  + ',' + val + ')');

    });    
}

$(function () {
    scaleToFill();

    $('.video-background').on('loadeddata', scaleToFill);

    $(window).resize(function() {
        scaleToFill();
    });
});

You can read database value in to a variable and then set the variable as follows

$app_container->assign('checked_flag', $db_data=='0'  ? '' : 'checked');

And in html you can just use the checked_flag variable as follows

<input type="checkbox" id="chk_test" name="chk_test" value="1" {checked_flag}>

Try this

To Remove Hand Cursor

a.link {
    cursor: default;
}

From your output:

no listening sockets available, shutting down

what basically means, that any port in which one apache is going to be listening is already being used by another application.

netstat -punta | grep LISTEN

Will give you a list of all the ports being used and the information needed to recognize which process is so you can kill stop or do whatever you want to do with it.

After doing a nmap of your ip I can see that

80/tcp    open     http

so I guess you sorted it out.

I have a way, you guys tell me how good it is.

Create a new object of the class and compare it with your object (which you want to check for emptiness).

To be correctly able to do it :

Override the hashCode() and equals() methods of your model class and also of the classes, objects of whose are members of your class, for example :

Person class (primary model class) :

public class Person {

    private int age;
    private String firstName;
    private String lastName;
    private Address address;

    //getters and setters

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((address == null) ? 0 : address.hashCode());
        result = prime * result + age;
        result = prime * result + ((firstName == null) ? 0 : firstName.hashCode());
        result = prime * result + ((lastName == null) ? 0 : lastName.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Person other = (Person) obj;
        if (address == null) {
            if (other.address != null)
                return false;
        } else if (!address.equals(other.address))
            return false;
        if (age != other.age)
            return false;
        if (firstName == null) {
            if (other.firstName != null)
                return false;
        } else if (!firstName.equals(other.firstName))
            return false;
        if (lastName == null) {
            if (other.lastName != null)
                return false;
        } else if (!lastName.equals(other.lastName))
            return false;
        return true;
    }

    @Override
    public String toString() {
        return "Person [age=" + age + ", firstName=" + firstName + ", lastName=" + lastName + ", address=" + address
                + "]";
    }

}

Address class (used inside Person class) :

public class Address {

    private String line1;
    private String line2;

    //getters and setters

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((line1 == null) ? 0 : line1.hashCode());
        result = prime * result + ((line2 == null) ? 0 : line2.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Address other = (Address) obj;
        if (line1 == null) {
            if (other.line1 != null)
                return false;
        } else if (!line1.equals(other.line1))
            return false;
        if (line2 == null) {
            if (other.line2 != null)
                return false;
        } else if (!line2.equals(other.line2))
            return false;
        return true;
    }

    @Override
    public String toString() {
        return "Address [line1=" + line1 + ", line2=" + line2 + "]";
    }

}

Now in the main class :

    Person person1 = new Person();
    person1.setAge(20);

    Person person2 = new Person();

    Person person3 = new Person();

if(person1.equals(person2)) --> this will be false

if(person2.equals(person3)) --> this will be true

I hope this is the best way instead of putting if conditions on each and every member variables.

Let me know !

To send an objective-c message in this instance you would do

[self score];

I suggest you read the Objective-C programming guide Objective-C Programming Guide

I agree with all the performance and readability posts. However, there are cases where it really does matter. A couple other people mentioned this, but it might be easier to see with examples.

Consider this slightly modified example:

public static void main(String[] args) {
    String[] myNumberStrings = new String[] {"1.2345", "asdf", "2.3456"};
    ArrayList asNumbers = parseAll(myNumberStrings);
}

public static ArrayList parseAll(String[] numberStrings){
    ArrayList myFloats = new ArrayList();

    for(int i = 0; i < numberStrings.length; i++){
        myFloats.add(new Float(numberStrings[i]));
    }
    return myFloats;
}

If you want the parseAll() method to return null if there are any errors (like the original example), you'd put the try/catch on the outside like this:

public static ArrayList parseAll1(String[] numberStrings){
    ArrayList myFloats = new ArrayList();
    try{
        for(int i = 0; i < numberStrings.length; i++){
            myFloats.add(new Float(numberStrings[i]));
        }
    } catch (NumberFormatException nfe){
        //fail on any error
        return null;
    }
    return myFloats;
}

In reality, you should probably return an error here instead of null, and generally I don't like having multiple returns, but you get the idea.

On the other hand, if you want it to just ignore the problems, and parse whatever Strings it can, you'd put the try/catch on the inside of the loop like this:

public static ArrayList parseAll2(String[] numberStrings){
    ArrayList myFloats = new ArrayList();

    for(int i = 0; i < numberStrings.length; i++){
        try{
            myFloats.add(new Float(numberStrings[i]));
        } catch (NumberFormatException nfe){
            //don't add just this one
        }
    }

    return myFloats;
}

Understanding Looper Threads

A java Thread a unit of execution which was designed to perform a task in its run() method & terminate after that:

But in Android there are many use cases where we need to keep a Thread alive and wait for user inputs/events for eg. UI thread aka Main Thread.

Main thread in Android is a Java thread which is first started by JVM at the launch of an app and keeps on running till the user choose to close it or encounters unhandled exception.

When an application is launched, the system creates a thread of execution for the application, called "main." This thread is very important because it is in charge of dispatching events to the appropriate user interface widgets, including drawing events.

Now point to note here is although main thread is Java thread yet it keeps on listening to user events and draw 60 fps frames on screen and still it wont die after each cycle. how is it so?

The answer is Looper Class: Looper is a class which is used to keep a thread alive and manage a message queue to execute tasks on that thread.

Threads by default do not have a message loop associated with them but you can assign one by calling Looper.prepare() in the run method and then call the Looper.loop().

Purpose of Looper is to keep a Thread alive and wait for next cycle of input Message object to perform computation which otherwise will get destroyed after first cycle of execution.

If you want to dig deeper how Looper manage Message object queue then you can have a look at source code of Looperclass:

https://github.com/aosp-mirror/platform_frameworks_base/blob/master/core/java/android/os/Looper.java

Below is an example of how you can create a Looper Thread and communicate with Activity class using LocalBroadcast

class LooperThread : Thread() {

    // sendMessage success result on UI
    private fun sendServerResult(result: String) {
        val resultIntent = Intent(ServerService.ACTION)
        resultIntent.putExtra(ServerService.RESULT_CODE, Activity.RESULT_OK)
        resultIntent.putExtra(ServerService.RESULT_VALUE, result)
        LocalBroadcastManager.getInstance(AppController.getAppController()).sendBroadcast(resultIntent)
    }

    override fun run() {
        val looperIsNotPreparedInCurrentThread = Looper.myLooper() == null

        // Prepare Looper if not already prepared
        if (looperIsNotPreparedInCurrentThread) {
            Looper.prepare()
        }

        // Create a handler to handle messaged from Activity
        handler = Handler(Handler.Callback { message ->
            // Messages sent to Looper thread will be visible here
            Log.e(TAG, "Received Message" + message.data.toString())

            //message from Activity
            val result = message.data.getString(MainActivity.BUNDLE_KEY)

            // Send Result Back to activity
            sendServerResult(result)
            true
        })

        // Keep on looping till new messages arrive
        if (looperIsNotPreparedInCurrentThread) {
            Looper.loop()
        }
    }

    //Create and send a new  message to looper
    fun sendMessage(messageToSend: String) {
        //Create and post a new message to handler
        handler!!.sendMessage(createMessage(messageToSend))
    }


    // Bundle Data in message object
    private fun createMessage(messageToSend: String): Message {
        val message = Message()
        val bundle = Bundle()
        bundle.putString(MainActivity.BUNDLE_KEY, messageToSend)
        message.data = bundle
        return message
    }

    companion object {
        var handler: Handler? = null // in Android Handler should be static or leaks might occur
        private val TAG = javaClass.simpleName

    }
}

Usage:

 class MainActivity : AppCompatActivity() {

    private var looperThread: LooperThread? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // start looper thread
        startLooperThread()

        // Send messages to Looper Thread
        sendMessage.setOnClickListener {

            // send random messages to looper thread
            val messageToSend = "" + Math.random()

            // post message
            looperThread!!.sendMessage(messageToSend)

        }   
    }

    override fun onResume() {
        super.onResume()

        //Register to Server Service callback
        val filterServer = IntentFilter(ServerService.ACTION)
        LocalBroadcastManager.getInstance(this).registerReceiver(serverReceiver, filterServer)

    }

    override fun onPause() {
        super.onPause()

        //Stop Server service callbacks
     LocalBroadcastManager.getInstance(this).unregisterReceiver(serverReceiver)
    }


    // Define the callback for what to do when data is received
    private val serverReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context, intent: Intent) {
            val resultCode = intent.getIntExtra(ServerService.RESULT_CODE, Activity.RESULT_CANCELED)
            if (resultCode == Activity.RESULT_OK) {
                val resultValue = intent.getStringExtra(ServerService.RESULT_VALUE)
                Log.e(MainActivity.TAG, "Server result : $resultValue")

                serverOutput.text =
                        (serverOutput.text.toString()
                                + "\n"
                                + "Received : " + resultValue)

                serverScrollView.post( { serverScrollView.fullScroll(View.FOCUS_DOWN) })
            }
        }
    }

    private fun startLooperThread() {

        // create and start a new LooperThread
        looperThread = LooperThread()
        looperThread!!.name = "Main Looper Thread"
        looperThread!!.start()

    }

    companion object {
        val BUNDLE_KEY = "handlerMsgBundle"
        private val TAG = javaClass.simpleName
    }
}

Can we use Async task or Intent Services instead?

• Async tasks are designed to perform a short operation in background and give progres & results on UI thread. Async tasks have limits like you cant create more than 128 Async tasks and ThreadPoolExecutor will allow only upto 5 Async tasks.

• IntentServices are also designed to do background task for a little longer duration and you can use LocalBroadcast to communicate with Activity. But services get destroyed after task execution. If you want to keep it running for a long time than you need to do hecks like while(true){...}.

Other meaningful use cases for Looper Thread:

• Used for 2 way socket communication where server keep on listening to Client socket and write back acknowledgment

• Bitmap processing in background. Pass the image url to Looper thread and it will apply filter effects and store it in tempe rory location and then broadcast temp path of image.

I had a similar issue and it turned out that i had to add an extra entry in cmake to include the files.

Since i was also using the zmq library I had to add this to the included libraries as well.
