They are pretty similar with some small differences, first one is a variable which assigned to an anonymous function (Function Declaration) and second one is the normal way to create a function in JavaScript(Anonymous function Declaration), both has usage, cons and pros:

1. Function Expression

var functionOne = function() {
    // Some code
};

A Function Expression defines a function as a part of a larger expression syntax (typically a variable assignment ). Functions defined via Functions Expressions can be named or anonymous. Function Expressions must not start with “function” (hence the parentheses around the self invoking example below).

Assign a variable to a function, means no Hoisting, as we know functions in JavaScript can Hoist, means they can be called before they get declared, while variables need to be declared before getting access to them, so means in this case we can not access the function before where it's declared, also it could be a way that you write your functions, for the functions which return another function, this kind of declaration could make sense, also in ECMA6 & above you can assign this to an arrow function which can be used to call anonymous functions, also this way of declaring is a better way to create Constructor functions in JavaScript.

2. Function Declaration

function functionTwo() {
    // Some code
}

A Function Declaration defines a named function variable without requiring variable assignment. Function Declarations occur as standalone constructs and cannot be nested within non-function blocks. It’s helpful to think of them as siblings of Variable Declarations. Just as Variable Declarations must start with “var”, Function Declarations must begin with “function”.

This is the normal way of calling a function in JavaScript, this function can be called before you even declare it as in JavaScript all functions get Hoisted, but if you have 'use strict' this won't Hoist as expected, it's a good way to call all normal functions which are not big in lines and neither are a constructor function.

Also, if you need more info about how hoisting works in JavaScript, visit the link below:

Preamble for micro-optimizer people

Remember:

"Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%".

(Thanks to metamorphosis for the full quote)

Don't use a C array instead of a vector (or whatever) just because you believe it's faster as it is supposed to be lower-level. You would be wrong.

Use by default vector (or the safe container adapted to your need), and then if your profiler says it is a problem, see if you can optimize it, either by using a better algorithm, or changing container.

This said, we can go back to the original question.

Static/Dynamic Array?

The C++ array classes are better behaved than the low-level C array because they know a lot about themselves, and can answer questions C arrays can't. They are able to clean after themselves. And more importantly, they are usually written using templates and/or inlining, which means that what appears to a lot of code in debug resolves to little or no code produced in release build, meaning no difference with their built-in less safe competition.

All in all, it falls on two categories:

Dynamic arrays

Using a pointer to a malloc-ed/new-ed array will be at best as fast as the std::vector version, and a lot less safe (see litb's post).

So use a std::vector.

Static arrays

Using a static array will be at best:

• as fast as the std::array version
• and a lot less safe.

So use a std::array.

Uninitialized memory

Sometimes, using a vector instead of a raw buffer incurs a visible cost because the vector will initialize the buffer at construction, while the code it replaces didn't, as remarked bernie by in his answer.

If this is the case, then you can handle it by using a unique_ptr instead of a vector or, if the case is not exceptional in your codeline, actually write a class buffer_owner that will own that memory, and give you easy and safe access to it, including bonuses like resizing it (using realloc?), or whatever you need.

Unfortunately, the most common use of <a href="#"> is by lazy programmers who want clickable non-hyperlink javascript-coded elements that behave like anchors, but they can't be arsed to add cursor: pointer; or :hover styles to a class for their non-hyperlink elements, and are additionally too lazy to set href to javascript:void(0);.

The problem with this is that one <a href="#" onclick="some_function();"> or another inevitably ends up with a javascript error, and an anchor with an onclick javascript error always ends up following its href. Normally this ends up being an annoying jump to the top of the page, but in the case of sites using <base>, <a href="#"> is handled as <a href="[base href]/#">, resulting in an unexpected navigation. If any logable errors are being generated, you won't see them in the latter case unless you enable persistent logs.

If an anchor element is used as a non-anchor it should have its href set to javascript:void(0); for the sake of graceful degradation.

I just wasted two days debugging a random unexpected page redirect that should have simply refreshed the page, and finally tracked it down to a function raising the click event of an <a href="#">. Replacing the # with javascript:void(0); fixed it.

The first thing I'm doing Monday is purging the project of all instances of <a href="#">.

You have to use GROUP BY so you will have multiple records returned,

SELECT  COUNT(*) TotalCount, 
        b.category_id, 
        b.category_name 
FROM    table1 a
        INNER JOIN table2 b
            ON a.category_id = b.category_id 
WHERE   a.colour <> 'red'
GROUP   BY b.category_id, b.category_name

What I have done with no memory leaks or lint warnings is to use @f.trajkovski's method, but instead of using MainActivity, use WeakReference<MainActivity> instead.

public class MainActivity extends AppCompatActivity {
public static WeakReference<MainActivity> weakActivity;
// etc..
 public static MainActivity getmInstanceActivity() {
    return weakActivity.get();
}
}

Then in MainActivity OnCreate()

weakActivity = new WeakReference<>(MainActivity.this);

Then in another class

MainActivity.getmInstanceActivity().yourMethod();

Works like a charm

Add the following into /etc/mysql/cnf file:

innodb_buffer_pool_size = 64M

example:

key_buffer              = 16M
max_allowed_packet      = 16M
thread_stack            = 192K
thread_cache_size       = 8
innodb_buffer_pool_size = 64M

I had faced the same problem.By selecting wipe data worked for me.

You don't need order by in your sub query. Move it out into the main query, and include the column you want to order by in the subquery.

however, your query is just returning a count, so I don't see the point of the order by.

Super easy and works, but not sure why....

angular.module('testing')
  .directive('details', function () {
        return {
              templateUrl: 'components/details.template.html',
              restrict: 'E',                 
              controller: function ($scope) {
                    $scope.details=$scope.details;  <=== can see the parent details doing this                     
              }
        };
  });

Thanks for all Contributions;

that is happening with me in XML; I just Change application/XML to be text/XML which solve my Problem

If you have something like

Uncaught SyntaxError: embedded: Unexpected token

You probably missed a comma in a place like this:

  var CommentForm = React.createClass({
  getInitialState: function() {
      return {author: '', text: ''};

  }, // <---- DON'T FORGET THE COMMA

  render: function() {
      return (
      <form className="commentForm">
          <input type="text" placeholder="Nombre" />
          <input type="text" placeholder="Qué opina" />
          <input type="submit" value="Publicar" />
      </form>
      )
  }
  });

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

for random every RUN file

size_t randomGenerator(size_t min, size_t max) {
    std::mt19937 rng;
    rng.seed(std::random_device()());
    //rng.seed(std::chrono::high_resolution_clock::now().time_since_epoch().count());
    std::uniform_int_distribution<std::mt19937::result_type> dist(min, max);

    return dist(rng);
}

The BigDecimal(double) constructor can have unpredictable behaviors. It is preferable to use BigDecimal(String) or BigDecimal.valueOf(double).

System.out.println(new BigDecimal(135.69)); //135.68999999999999772626324556767940521240234375
System.out.println(new BigDecimal("135.69")); // 135.69
System.out.println(BigDecimal.valueOf(135.69)); // 135.69

The documentation for BigDecimal(double) explains in detail:

1. The results of this constructor can be somewhat unpredictable. One might assume that writing new BigDecimal(0.1) in Java creates a BigDecimal which is exactly equal to 0.1 (an unscaled value of 1, with a scale of 1), but it is actually equal to 0.1000000000000000055511151231257827021181583404541015625. This is because 0.1 cannot be represented exactly as a double (or, for that matter, as a binary fraction of any finite length). Thus, the value that is being passed in to the constructor is not exactly equal to 0.1, appearances notwithstanding.
2. The String constructor, on the other hand, is perfectly predictable: writing new BigDecimal("0.1") creates a BigDecimal which is exactly equal to 0.1, as one would expect. Therefore, it is generally recommended that the String constructor be used in preference to this one.
3. When a double must be used as a source for a BigDecimal, note that this constructor provides an exact conversion; it does not give the same result as converting the double to a String using the Double.toString(double) method and then using the BigDecimal(String) constructor. To get that result, use the static valueOf(double) method.

In python3.x it can be done using :

# Converting lat/long to cartesian
import numpy as np

def get_cartesian(lat=None,lon=None):
    lat, lon = np.deg2rad(lat), np.deg2rad(lon)
    R = 6371 # radius of the earth
    x = R * np.cos(lat) * np.cos(lon)
    y = R * np.cos(lat) * np.sin(lon)
    z = R *np.sin(lat)
    return x,y,z

Use a JQuery selector:

$("label[for="+inputElement.id+"]")

If you're using gradle, you can use:

./gradlew bootRun

As you're using Python 3, there is no urllib module anymore. It has been split into several modules.

This would be equivalent to urlretrieve:

import urllib.request
data = urllib.request.urlretrieve("http://...")

urlretrieve behaves exactly the same way as it did in Python 2.x, so it'll work just fine.

Basically:

• urlretrieve saves the file to a temporary file and returns a tuple (filename, headers)
• urlopen returns a Request object whose read method returns a bytestring containing the file contents

Assuming you're using SQL Server, use DATEPART with dw:

SELECT date_created
FROM your_table
WHERE DATEPART(dw, date_created) NOT IN (1, 7);

EDIT: I should point out that the actual numeric value returned by DATEPART(dw) is determined by the value set by using SET DATEFIRST:
http://msdn.microsoft.com/en-us/library/ms181598.aspx

Exemple, for :

<div id="myBlock" style="margin: 10px 0px 15px 5px:"></div>

In this js code :

var myMarginTop = $("#myBlock").css("marginBottom");

The var becomes "15px", a string.

If you want an Integer, to avoid NaN (Not a Number), there is multiple ways.

The fastest is to use native js method :

var myMarginTop = parseInt( $("#myBlock").css("marginBottom") );

This should work...

JavaScriptSerializer ser = new JavaScriptSerializer();
var records = new ser.Deserialize<List<Record>>(jsonData);

public class Person
{
    public string Name;
    public int Age;
    public string Location;
}
public class Record
{
    public Person record;
}

You can detect a lot of heap corruption problems by enabling Page Heap for your application . To do this you need to use gflags.exe that comes as a part of Debugging Tools For Windows

Run Gflags.exe and in the Image file options for your executable, check "Enable Page Heap" option.

Now restart your exe and attach to a debugger. With Page Heap enabled, the application will break into debugger whenever any heap corruption occurs.

The YUI example above should really be:

<script>
  YAHOO.util.Event.onDOMReady(function() {   
     Dom.get("foo").onclick =  function (){alert('foo');};
  });
</script>

mingw32 exists as a package for Linux. You can cross-compile and -link Windows applications with it. There's a tutorial here at the Code::Blocks forum. Mind that the command changes to x86_64-w64-mingw32-gcc-win32, for example.

Ubuntu, for example, has MinGW in its repositories:

$ apt-cache search mingw
[...]
g++-mingw-w64 - GNU C++ compiler for MinGW-w64
gcc-mingw-w64 - GNU C compiler for MinGW-w64
mingw-w64 - Development environment targeting 32- and 64-bit Windows
[...]

• First line : array created.
• Third line loop started from j = 1 to j = 28123
• Fourth line you give the variable x value (0) each time the loop is accessed.
• Fifth line you put the value of j in the index 0.
• Sixth line you do increment to the value x by 1.(but it will be reset to 0 at line 4)

Python lacks the tail recursion optimizations common in functional languages like lisp. In Python, recursion is limited to 999 calls (see sys.getrecursionlimit).

If 999 depth is more than you are expecting, check if the implementation lacks a condition that stops recursion, or if this test may be wrong for some cases.

I dare to say that in Python, pure recursive algorithm implementations are not correct/safe. A fib() implementation limited to 999 is not really correct. It is always possible to convert recursive into iterative, and doing so is trivial.

It is not reached often because in many recursive algorithms the depth tend to be logarithmic. If it is not the case with your algorithm and you expect recursion deeper than 999 calls you have two options:

1) You can change the recursion limit with sys.setrecursionlimit(n) until the maximum allowed for your platform:

sys.setrecursionlimit(limit):

Set the maximum depth of the Python interpreter stack to limit. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python.

The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a crash.

2) You can try to convert the algorithm from recursive to iterative. If recursion depth is bigger than allowed by your platform, it is the only way to fix the problem. There are step by step instructions on the Internet and it should be a straightforward operation for someone with some CS education. If you are having trouble with that, post a new question so we can help.

The safest way to pass commands to psql in a script is by piping a string or passing a here-doc.

The man docs for the -c/--command option goes into more detail when it should be avoided.

   -c command
   --command=command
       Specifies that psql is to execute one command string, command, and then exit. This is useful in shell scripts. Start-up files (psqlrc and ~/.psqlrc)
       are ignored with this option.

       command must be either a command string that is completely parsable by the server (i.e., it contains no psql-specific features), or a single
       backslash command. Thus you cannot mix SQL and psql meta-commands with this option. To achieve that, you could pipe the string into psql, for
       example: echo '\x \\ SELECT * FROM foo;' | psql. (\\ is the separator meta-command.)

       If the command string contains multiple SQL commands, they are processed in a single transaction, unless there are explicit BEGIN/COMMIT commands
       included in the string to divide it into multiple transactions. This is different from the behavior when the same string is fed to psql's standard
       input. Also, only the result of the last SQL command is returned.

       Because of these legacy behaviors, putting more than one command in the -c string often has unexpected results. It's better to feed multiple
       commands to psql's standard input, either using echo as illustrated above, or via a shell here-document, for example:

           psql <<EOF
           \x
           SELECT * FROM foo;
           EOF

Redirect stderr to stdout

This will redirect the stderr (which is descriptor 2) to the file descriptor 1 which is the the stdout.

2>&1

Redirect stdout to File

Now when perform this you are redirecting the stdout to the file sample.s

myprogram > sample.s

Redirect stderr and stdout to File

Combining the two commands will result in redirecting both stderr and stdout to sample.s

myprogram > sample.s 2>&1

Redirect stderr and stdout to /dev/null

Redirect to /dev/null if you want to completely silent your application.

myprogram >/dev/null 2>&1

wait.until(ExpectedConditions) won't return null, it will either meet the condition or throw TimeoutException.

You can check if the element is displayed and enabled

WebElement element = driver.findElement(By.xpath);
if (element.isDisplayed() && element.isEnabled()) {
    element.click();
}

Note that textarea[readonly="readonly"] works if you set readonly="readonly" in HTML but it does NOT work if you set the readOnly-attribute to true or "readonly" via JavaScript.

For the CSS selector to work if you set readOnly with JavaScript you have to use the selector textarea[readonly].

Same behavior in Firefox 14 and Chrome 20.

To be on the safe side, i use both selectors.

textarea[readonly="readonly"], textarea[readonly] {
...
}

I ran into the same issue recently working with a batch file on a network share drive in Windows 7.

Another way that worked for me was to map the server to a drive through Windows Explorer: Tools -> Map network drive. Give it a drive letter and folder path to \yourserver. Since I work with the network share often mapping to it makes it more convenient, and it resolved the “UNC path are not supported” error.

If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw always interrupt the execution flow of the current method. a try/catch block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.

Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/

You need to be in the directory of the file and then type the following into the terminal

git reset HEAD .

Assumption is that you need to reset one file only.

I have used JMF on a videoconference application and it worked well on two laptops: one with integrated webcam and another with an old USB webcam. It requires JMF being installed and configured before-hand, but once you're done you can access the hardware via Java code fairly easily.

What about overriding the method with

void f(int value)
{
  f((byte)value);
}

this will allow for f(0)

We faced the same issue and changed commandname="" to modelAttribute="" in jsp page to solve this issue.

Why is that not acceptable?

document.getElementById('test').innerHTML += str

would be the textbook way of doing it.

MS's query explaining the use of the KILL command is quite useful providing connection's information:

SELECT conn.session_id, host_name, program_name,
    nt_domain, login_name, connect_time, last_request_end_time 
FROM sys.dm_exec_sessions AS sess
JOIN sys.dm_exec_connections AS conn
   ON sess.session_id = conn.session_id;

It should be possible to create custom java agent that overrides default HostnameVerifier:

import javax.net.ssl.*;
import java.lang.instrument.Instrumentation;

public class LenientHostnameVerifierAgent {
    public static void premain(String args, Instrumentation inst) {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });
    }
}

Then just add -javaagent:LenientHostnameVerifierAgent.jar to program's java startup arguments.

For SQL Server 2012, or later, an easier solution is to use FORMAT ()^{Documentation}.
EG:

SELECT Format(1234567.8, '##,##0') 

Results in: 1,234,568

It don't create normally; you need to add it by yourself.

After adding Global.asax by

• Right clicking your website -> Add New Item -> Global Application Class -> Add

You need to add a class

• Right clicking App_Code -> Add New Item -> Class -> name it Global.cs -> Add

Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.

Your Global.asax will look like this: -

<%@ Application Language="C#" Inherits="Global" %>

Your Global.cs in App_Code will look like this: -

public class Global : System.Web.HttpApplication
{
    public Global()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
    /// Many other events like begin request...e.t.c, e.t.c
}

The varStatus references to LoopTagStatus which has a getIndex() method.

So:

<c:forEach var="tableEntity" items='${requestScope.tables}' varStatus="outer">
   <c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="inner">            
        <c:out value="${(outer.index * fn:length(tableEntity.rows)) + inner.index}" />
    </c:forEach>
</c:forEach>

use this

If you're going to have a method that just runs the switch and then returns some value, then sure this way works. But if you want a switch with other stuff in a method then you can't use return or the rest of the code inside the method will not execute. Notice in the tutorial how it has a print after the code? Yours would not be able to do this.

You can use jQuery change() function

$('input').change(function(){
  //your codes
});

There are examples on how to use it on the API Page: http://api.jquery.com/change/

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

I usually need this for commented code so I use curly brackets at start and end of that.

{
// Code
// Code
// Code
// Code
}

It could be used for code snippets but can create problems in some code because it changes the scope of variable.

In Sequelize version 5 you might also can use this way (full use Operator Sequelize) :

var condition = 
{ 
  [Op.or]: [ 
   { 
     LastName: {
      [Op.eq]: "Doe"
      },
    },
   { 
     FirstName: {
      [Op.or]: ["John", "Jane"]
      }
   },
   {
      Age:{
        [Op.gt]: 18
      }
    }
 ]
}

And then, you must include this :

const Op = require('Sequelize').Op

and pass it in :

Student.findAll(condition)
.success(function(students){ 
//
})

It could beautifully generate SQL like this :

"SELECT * FROM Student WHERE LastName='Doe' OR FirstName in ("John","Jane") OR Age>18"

You could also use FilenameUtils from Apache. It provides you at least the following features for the example C:\dev\project\file.txt:

• the prefix - C:\
• the path - dev\project\
• the full path - C:\dev\project\
• the name - file.txt
• the base name - file
• the extension - txt

This is not really easiest way but this source code enable you to right any types of octal number i.e 23.214, 23 and 0.512 and so on. Hope this will help you..

    public string octal_to_decimal(string m_value)

It is possible to build an arbitrary GET or POST request and send it to any server accessible to a victims browser. This includes devices on your local network, such as Printers and Routers.

There are many ways of building a CSRF exploit. A simple POST based CSRF attack can be sent using .submit() method. More complex attacks, such as cross-site file upload CSRF attacks will exploit CORS use of the xhr.withCredentals behavior.

CSRF does not violate the Same-Origin Policy For JavaScript because the SOP is concerned with JavaScript reading the server's response to a clients request. CSRF attacks don't care about the response, they care about a side-effect, or state change produced by the request, such as adding an administrative user or executing arbitrary code on the server.

Make sure your requests are protected using one of the methods described in the OWASP CSRF Prevention Cheat Sheet. For more information about CSRF consult the OWASP page on CSRF.

You might want this (edit: allow number of the form 0123):

^\\+?[1-9]$|^\\+?\d+$

however, if it were me, I would instead do

int x = Integer.parseInt(s)
if (x > 0) {...}

This my program in ruby . It will return arrays, each holding the subsequences summing to the provided target value.

array = [1, 3, 4, 2, 7, 8, 9]

0..array.size.times.each do |i| 
  array.combination(i).to_a.each { |a| print a if a.inject(:+) == 9} 
end

CASE WHEN B.[STAT] IS NULL THEN (C.[EVENT DATE]+10)   -- Type DATETIME
     ELSE '-'                                         -- Type VARCHAR
     END AS [DATE]

You need to select one type or the other for the field, the field type can't vary by row. The simplest is to remove the ELSE '-' and let it implicitly get the value NULL instead for the second case.

For preventing naming conflicts, only import the variables that you need:

variableInFile () {
    variable="${1}"
    file="${2}"

    echo $(
        source "${file}";
        eval echo \$\{${variable}\}
    )
}

With

with() is for eager loading. That basically means, along the main model, Laravel will preload the relationship(s) you specify. This is especially helpful if you have a collection of models and you want to load a relation for all of them. Because with eager loading you run only one additional DB query instead of one for every model in the collection.

Example:

User > hasMany > Post

$users = User::with('posts')->get();
foreach($users as $user){
    $users->posts; // posts is already loaded and no additional DB query is run
}

Has

has() is to filter the selecting model based on a relationship. So it acts very similarly to a normal WHERE condition. If you just use has('relation') that means you only want to get the models that have at least one related model in this relation.

Example:

User > hasMany > Post

$users = User::has('posts')->get();
// only users that have at least one post are contained in the collection

WhereHas

whereHas() works basically the same as has() but allows you to specify additional filters for the related model to check.

Example:

User > hasMany > Post

$users = User::whereHas('posts', function($q){
    $q->where('created_at', '>=', '2015-01-01 00:00:00');
})->get();
// only users that have posts from 2015 on forward are returned

Best way to avoid OOM during Bitmap creation,

Got this from Bing. Seems Microsoft has removed some features from the core framework and added it to a separate optional(?) framework component.

To quote from MSDN (http://msdn.microsoft.com/en-us/library/cc656912.aspx)

The .NET Framework 4 Client Profile does not include the following features. You must install the .NET Framework 4 to use these features in your application:

* ASP.NET
* Advanced Windows Communication Foundation (WCF) functionality
* .NET Framework Data Provider for Oracle
* MSBuild for compiling

Few steps that helped me (some of them are mentioned above):

Open project structure by:

command + ; (mac users) OR right click on the project -> Open Module Settings

1. Facets -> + -> Python -> <your-project> -> OK
2. Modules -> Python -> <select python interpreter>
3. Project -> Project SDK -> <select relevant SDK>
4. SDKs -> <make sure it's the right one>

Click OK.

Open Run/Debug Configurations by: Run -> Edit Configurations

5. Python Interpreter -> <make sure it's the right one>

Click OK.

The problem here was a typo error in the password used, which was not easily identified due to the characters / letters used in the password.

Try:

document.getElementById("yourH1_element_Id").innerHTML = "yourTextHere";

'data' should be a stringified JavaScript object:

data: JSON.stringify({ "userName": userName, "password" : password })

To send your formData, pass it to stringify:

data: JSON.stringify(formData)

Some servers also require the application/json content type:

contentType: 'application/json'

There's also a more detailed answer to a similar question here: Jquery Ajax Posting json to webservice

Here is my simple solution using Jquery filters.

$('#publisher').on('change', function(e) {
   let selector = $(this).val();
   $("#site > option").hide();
   $("#site > option").filter(function(){return $(this).data('pub') == selector}).show();
});

JSFIDDLE

You have two approaches to this:

1. check the "keypress" event. If the user presses a special character key, stop him right there
2. check the "onblur" event: when the input element loses focus, validate its contents. If the value is invalid, display a discreet warning beside that input box.

I would suggest the second method because its less irritating. Remember to also check onpaste . If you use only keypress Then We Can Copy and paste special characters so use onpaste also to restrict Pasting special characters

Additionally, I will also suggest that you reconsider if you really want to prevent users from entering special characters. Because many people have $, #, @ and * in their passwords.

I presume that this might be in order to prevent SQL injection; if so: its better that you handle the checks server-side. Or better still, escape the values and store them in the database.

Another Simple way i found in Netbeans right click on your project>libraris click add jar/folder add your comm.jar and you done.

if you dont have comm.jar download it from >>> http://llk.media.mit.edu/projects/picdev/software/javaxcomm.zip

Based on the List Members Instance docs, the easiest way is to use a PUT request which according to the docs either "adds a new list member or updates the member if the email already exists on the list".

Furthermore apikey is definitely not part of the json schema and there's no point in including it in your json request.

Also, as noted in @TooMuchPete's comment, you can use CURLOPT_USERPWD for basic http auth as illustrated in below.

I'm using the following function to add and update list members. You may need to include a slightly different set of merge_fields depending on your list parameters.

$data = [
    'email'     => '[email protected]',
    'status'    => 'subscribed',
    'firstname' => 'john',
    'lastname'  => 'doe'
];

syncMailchimp($data);

function syncMailchimp($data) {
    $apiKey = 'your api key';
    $listId = 'your list id';

    $memberId = md5(strtolower($data['email']));
    $dataCenter = substr($apiKey,strpos($apiKey,'-')+1);
    $url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/lists/' . $listId . '/members/' . $memberId;

    $json = json_encode([
        'email_address' => $data['email'],
        'status'        => $data['status'], // "subscribed","unsubscribed","cleaned","pending"
        'merge_fields'  => [
            'FNAME'     => $data['firstname'],
            'LNAME'     => $data['lastname']
        ]
    ]);

    $ch = curl_init($url);

    curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $apiKey);
    curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json);                                                                                                                 

    $result = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    return $httpCode;
}

Just put quotes around the Environment variable (as you have done) :
if "%DevEnvDir%" == "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\"
but it's the way you put opening bracket without a space that is confusing it.

Works for me...

C:\if "%gtk_basepath%" == "C:\Program Files\GtkSharp\2.12\" (echo yes)
yes

The R file can't be generated if your layout contains errors. If your res folder is empty, then it's safe to assume that there's no res/layout folder with any layouts in it, but your activity is probably calling setContentView and not finding anything -- that qualifies as a problem with your layout.

CASE isn't used for flow control... for this, you would need to use IF...

But, there's a set-based solution to this problem instead of the procedural approach:

UPDATE tblEmployee
SET 
  InOffice = CASE WHEN @NewStatus = 'InOffice' THEN -1 ELSE InOffice END,
  OutOffice = CASE WHEN @NewStatus = 'OutOffice' THEN -1 ELSE OutOffice END,
  Home = CASE WHEN @NewStatus = 'Home' THEN -1 ELSE Home END
WHERE EmpID = @EmpID

Note that the ELSE will preserves the original value if the @NewStatus condition isn't met.

In batch you could do it like this:

@echo off

setlocal EnableDelayedExpansion

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do (
  set "var=%%sxyz"
  svn co "!var!"
)

If you don't need the variable !var! elsewhere in the loop, you could simplify that to

@echo off

setlocal

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do svn co "%%sxyz"

However, like C.B. I'd prefer PowerShell if at all possible:

$string_list = 'str1', 'str2', 'str3', ... 'str10'

$string_list | ForEach-Object {
  $var = "${_}xyz"   # alternatively: $var = $_ + 'xyz'
  svn co $var
}

Again, this could be simplified if you don't need $var elsewhere in the loop:

$string_list = 'str1', 'str2', 'str3', ... 'str10'
$string_list | ForEach-Object { svn co "${_}xyz" }

Don't do nl2br when you save it to the database. Do nl2br when you're displaying the text in HTML. I can strongly recommend to not store any HTML formatting in the database (unless you're using a rich HTML editor as well, in which case it would be silly not to).

A newline \n will just become a newline in the textarea.

The solution given by @Rufinus is great but if you have auto increments it will break it.

This code covers all cases and types:

public static boolean isNegative(Number number) {
    return (Double.doubleToLongBits(number.doubleValue()) & Long.MIN_VALUE) == Long.MIN_VALUE;
}

This method accepts any of the wrapper classes (Integer, Long, Float and Double) and thanks to auto-boxing any of the primitive numeric types (int, long, float and double) and simply checks it the high bit, which in all types is the sign bit, is set.

It returns true when passed any of:

• any negative int/Integer
• any negative long/Long
• any negative float/Float
• any negative double/Double
• Double.NEGATIVE_INFINITY
• Float.NEGATIVE_INFINITY

and false otherwise.

Be warned - this is a very old and cumbersome "solution".

By the way, you can use serialization technology to send strings, numbers or any objects which are support serialization (most of .NET data-storing classes & structs are [Serializable]). There, you should at first send Int32-length in four bytes to the stream and then send binary-serialized (System.Runtime.Serialization.Formatters.Binary.BinaryFormatter) data into it.

On the other side or the connection (on both sides actually) you definetly should have a byte[] buffer which u will append and trim-left at runtime when data is coming.

Something like that I am using:

namespace System.Net.Sockets
{
    public class TcpConnection : IDisposable
    {
        public event EvHandler<TcpConnection, DataArrivedEventArgs> DataArrive = delegate { };
        public event EvHandler<TcpConnection> Drop = delegate { };

        private byte[] _incomingData = new byte[0];

                    }
                }
                else
                    if (_incomingData.Length >= IntSize)
                    {
                        _objectDataLength = BitConverter.ToInt32(_incomingData.TakeLeft(IntSize), 0);
                        _incomingData = _incomingData.TrimLeft(IntSize);
                        exitWhile = false;
                    }
            }
            StartReceive();
        }


        public void Dispose() { DropConnection(); }
    }
}

That is just an example, you should edit it for your use.

If you pass a variable data (dictionary type) as context to a template, then you code should be:

{% for key, value in data.items %}
    <p>{{ key }} : {{ value }}</p> 
{% endfor %}

In Swift 4.1 and Xcode 9.4.1.

JSON POST approach example. To check internet connection add Reachability.h & .m files from https://developer.apple.com/library/archive/samplecode/Reachability/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007324-Intro-DontLinkElementID_2

func yourFunctionName {
    //Check internet connection
    let networkReachability = Reachability.forInternetConnection()
    let networkStatus:Int = (networkReachability?.currentReachabilityStatus())!.rawValue
    print(networkStatus)
    if networkStatus == NotReachable.rawValue {
        let msg = SharedClass.sharedInstance.noNetMsg//Message
        //Call alert from shared class
        SharedClass.sharedInstance.alert(view: self, title: "", message: msg)
    } else {
        //Call spinner from shared class
        SharedClass.sharedInstance.activityIndicator(view: self.view)//Play spinner

        let parameters = "Your parameters here"
        var request = URLRequest(url: URL(string: url)!)

        request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
        request.httpMethod = "POST"

        print("URL : \(request)")

        request.httpBody = parameters.data(using: .utf8)

        let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
            //Stop spinner
            SharedClass.sharedInstance.stopActivityIndicator() //Stop spinner
            //Print error in alert
            SharedClass.sharedInstance.alert(view: self, title: "", message: "\(String(describing: error!.localizedDescription))")
            return
            }

            SharedClass.sharedInstance.stopActivityIndicator() //Stop spinner

            if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
                print("statusCode should be 200, but is \(httpStatus.statusCode)")
                print("response = \(String(describing: response))")
            }

            do {
                let response = try JSONSerialization.jsonObject(with: data, options: []) as? [String: AnyObject]
                print(response!)
                //Your code here                    
            } catch let error as NSError {
                print(error)
            }
        }

        task.resume()

    }

}

If you have interest to use this function in SharedClass

//My shared class
import UIKit
class SharedClass: NSObject {

static let sharedInstance = SharedClass()

func postRequestFunction(apiName: String , parameters: String, onCompletion: @escaping (_ success: Bool, _ error: Error?, _ result: [String: Any]?)->()) {

    var URL =  "your URL here/index.php/***?"

    URL = URL.replacingOccurrences(of: "***", with: apiName)

    var request = URLRequest(url: URL(string: URL)!)
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    request.httpMethod = "POST"
    print("shared URL : \(request)")
    request.httpBody = parameters.data(using: .utf8)

    var returnRes:[String:Any] = [:]
    let task = URLSession.shared.dataTask(with: request) { data, response, error in

        if let error = error {
            onCompletion(false, error, nil)
        } else {
            guard let data = data else {
                onCompletion(false, error, nil)
                return
            }

            if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode == 200 {
                do {
                   returnRes = try JSONSerialization.jsonObject(with: data, options: []) as! [String : Any]
                    onCompletion(true, nil, returnRes)

                } catch let error as NSError {
                   onCompletion(false, error, nil)
                }
            } else {
                onCompletion(false, error, nil)
            }
        }
    }
    task.resume()
}


private override init() {

}

And finally call this function like this....

SharedClass.sharedInstance.postRequestFunction(apiName: "Your API name", parameters: parameters) { (success, error, result) in
    print(result!)
    if success {
        //Your code here
    } else {
        print(error?.localizedDescription ?? "")
    }
}

To use a ternary operator without else inside of an array or object declaration, you can use the ES6 spread operator, ...():

const cond = false;
const arr = [
  ...(cond ? ['a'] : []),
  'b',
];
    // ['b']

And for objects:

const cond = false;
const obj = {
  ...(cond ? {a: 1} : {}),
  b: 2,
};
    // {b: 2}

One more solution, which works for both numeric & character/factor data:

Mode <- function(x) {
  ux <- unique(x)
  ux[which.max(tabulate(match(x, ux)))]
}

On my dinky little machine, that can generate & find the mode of a 10M-integer vector in about half a second.

If your data set might have multiple modes, the above solution takes the same approach as which.max, and returns the first-appearing value of the set of modes. To return all modes, use this variant (from @digEmAll in the comments):

Modes <- function(x) {
  ux <- unique(x)
  tab <- tabulate(match(x, ux))
  ux[tab == max(tab)]
}

Using a subshell substitution to parse the words undoes all the work you are doing to put spaces together.

Try instead:

cat CSV_file | sed -n 1'p' | tr ',' '\n' | while read word; do
    echo $word
done

That also increases parallelism. Using a subshell as in your question forces the entire subshell process to finish before you can start iterating over the answers. Piping to a subshell (as in my answer) lets them work in parallel. This matters only if you have many lines in the file, of course.

The first solution is to use the java.util.Random class:

import java.util.Random;

Random rand = new Random();

// Obtain a number between [0 - 49].
int n = rand.nextInt(50);

// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;

Another solution is using Math.random():

double random = Math.random() * 49 + 1;

or

int random = (int)(Math.random() * 50 + 1);

I solved this by overriding the default Content-Type:

const config = { headers: {'Content-Type': 'application/json'} };
axios.put(url, content, config).then(response => {
    ...
});

Based on m experience, the default Conent-Type is application/x-www-form-urlencoded for strings, and application/json for objects (including arrays). Your server probably expects JSON.

<div style="position: relative; width: 250px;">_x000D_
  <div style="position: absolute; top: 0; right: 0; width: 100px; text-align:right;">_x000D_
    here_x000D_
  </div>_x000D_
  <div style="position: absolute; bottom: 0; right: 0; width: 100px; text-align:right;">_x000D_
    and here_x000D_
  </div>_x000D_
  Lorem Ipsum etc <br />_x000D_
  blah <br />_x000D_
  blah blah <br />_x000D_
  blah <br />_x000D_
  lorem ipsums_x000D_
</div>

Gets you pretty close, although you may need to tweak the "top" and "bottom" values.

A simple thing you can do is position your fixed DIV relative to the rest of your page with % values.

Check out this jsfiddle here where the fixed DIV is a sidebar.

div#wrapper {
    margin: auto;
    width: 80%;
}

div#main {
    width: 60%;
}

div#sidebar {
    position: fixed;
    width: 30%;
    left: 60%;
}

And a brief picture below describing the layout above:

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

  public Optional<String> InputStreamToBase64(Optional<InputStream> inputStream) throws IOException{
    if (inputStream.isPresent()) {
        ByteArrayOutputStream outpString base64Image = data.split(",")[1];
byte[] imageBytes = javax.xml.bind.DatatypeConverter.parseBase64Binary(base64Image);

Then you can do whatever you like with the bytes like:

BufferedImage img = ImageIO.read(new ByteArrayInputStream(imageBytes));ut = new ByteArrayOutputStream();
        FileCopyUtils.copy(inputStream.get(), output);
        //TODO retrieve content type from file, & replace png below with it
        return Optional.ofNullable("data:image/png;base64," + DatatypeConverter.printBase64Binary(output.toByteArray()));
    }

    return Optional.empty();

In WPF an image is typically loaded from a Stream or an Uri.

BitmapImage supports both and an Uri can even be passed as constructor argument:

var uri = new Uri("http://...");
var bitmap = new BitmapImage(uri);

If the image file is located in a local folder, you would have to use a file:// Uri. You could create such a Uri from a path like this:

var path = Path.Combine(Environment.CurrentDirectory, "Bilder", "sas.png");
var uri = new Uri(path);

If the image file is an assembly resource, the Uri must follow the the Pack Uri scheme:

var uri = new Uri("pack://application:,,,/Bilder/sas.png");

In this case the Visual Studio Build Action for sas.png would have to be Resource.

Once you have created a BitmapImage and also have an Image control like in this XAML

<Image Name="image1" />

you would simply assign the BitmapImage to the Source property of that Image control:

image1.Source = bitmap;

actually I found a novel solution that really helped me out, If you are especially concerned with the index of a certain value in a list or data set, you can just set the value of dictionary to that Index!:

Just watch:

list = ['a', 'b', 'c']
dictionary = {}
counter = 0
for i in list:
   dictionary[i] = counter
   counter += 1

print(dictionary) # dictionary = {'a':0, 'b':1, 'c':2}

Now through the power of hashmaps you can pull the index your entries in constant time (aka a whole lot faster)

This topic is actually a little more complicated as described in the answers so far. This blogpost by Rob Norris explains it in more detail and gives examples on when using return will actually break your code (or at least have non-obvious effects).

At this point let me just quote the essence of the post. The most important statement is right in the beginning. Print this as a poster and put it to your wall :-)

The return keyword is not “optional” or “inferred”; it changes the meaning of your program, and you should never use it.

It gives one example, where it actually breaks something, when you inline a function

// Inline add and addR
def sum(ns: Int*): Int = ns.foldLeft(0)((n, m) => n + m) // inlined add

scala> sum(33, 42, 99)
res2: Int = 174 // alright

def sumR(ns: Int*): Int = ns.foldLeft(0)((n, m) => return n + m) // inlined addR

scala> sumR(33, 42, 99)
res3: Int = 33 // um.

because

A return expression, when evaluated, abandons the current computation and returns to the caller of the method in which return appears.

This is only one of the examples given in the linked post and it's the easiest to understand. There're more and I highly encourage you, to go there, read and understand.

When you come from imperative languages like Java, this might seem odd at first, but once you get used to this style it will make sense. Let me close with another quote:

If you find yourself in a situation where you think you want to return early, you need to re-think the way you have defined your computation.

#! /bin/bash

remove the indicated space. The shebang should be

        //get start of week; QT
    function _getStartOfWeek (date){
        var iDayOfWeek = date.getDay();
        var iDifference = date.getDate() - iDayOfWeek + (iDayOfWeek === 0 ?  -6:1);

        return new Date(date.setDate(iDifference));
    }, 

    function _getEndOfWeek(date){
        return new Date(date.setDate(date.getDate() + (7 - date.getDay()) === 7 ? 0 : (7 - date.getDay()) ));
    }, 

*current date == 30.06.2016 and monday is the first day in week.

It also works for different months and years. Tested with qunit suite:

        QUnit.module("Planung: Start of week");
    QUnit.test("Should return start of week based on current date", function (assert) {
        var startOfWeek = Planung._getStartOfWeek(new Date());
        assert.ok( startOfWeek , "returned date: "+ startOfWeek);
    });

    QUnit.test("Should return start of week based on a sunday date", function (assert) {
        var startOfWeek = Planung._getStartOfWeek(new Date("2016-07-03"));
        assert.ok( startOfWeek , "returned date: "+ startOfWeek);
    });

    QUnit.test("Should return start of week based on a monday date", function (assert) {
        var startOfWeek = Planung._getStartOfWeek(new Date("2016-06-27"));
        assert.ok( startOfWeek , "returned date: "+ startOfWeek);
    });

    QUnit.module("Planung: End of week");
    QUnit.test("Should return end of week based on current date", function (assert) {
        var endOfWeek = Planung._getEndOfWeek(new Date());
        assert.ok( endOfWeek , "returned date: "+ endOfWeek);
    });
    QUnit.test("Should return end of week based on sunday date with different month", function (assert) {
        var endOfWeek = Planung._getEndOfWeek(new Date("2016-07-03"));
        assert.ok( endOfWeek , "returned date: "+ endOfWeek);
    });
    QUnit.test("Should return end of week based on monday date with different month", function (assert) {
        var endOfWeek = Planung._getEndOfWeek(new Date("2016-06-27"));
        assert.ok( endOfWeek , "returned date: "+ endOfWeek);
    });
    QUnit.test("Should return end of week based on 01-06-2016 with different month", function (assert) {
        var endOfWeek = Planung._getEndOfWeek(new Date("2016-06-01"));
        assert.ok( endOfWeek , "returned date: "+ endOfWeek);
    });
    QUnit.test("Should return end of week based on 21-06-2016 with different month", function (assert) {
        var endOfWeek = Planung._getEndOfWeek(new Date("2016-06-21"));
        assert.ok( endOfWeek , "returned date: "+ endOfWeek);
    });
    QUnit.test("Should return end of week based on 28-12-2016 with different month and year", function (assert) {
        var endOfWeek = Planung._getEndOfWeek(new Date("2016-12-28"));
        assert.ok( endOfWeek , "returned date: "+ endOfWeek);
    });
    QUnit.test("Should return end of week based on 01-01-2016 with different month and year", function (assert) {
        var endOfWeek = Planung._getEndOfWeek(new Date("2016-01-01"));
        assert.ok( endOfWeek , "returned date: "+ endOfWeek);
    });

You have to make classpath in pom file for your dependency. Therefore you have to copy all the dependencies into one place.

I got the same error and found the cause to be a wrong or missing foreign key. (Using JDBC)

There are several ways to accomplish this, each with its own intended purpose.

1.) To use inline while simply assigning an element a list of things to do

$('#ele_id').css('display', 'block').animate(....
$('#ele_id').css('display', 'none').animate(....

2.) To use while setting multiple CSS properties

$('#ele_id').css({
    display: 'none'
    height: 100px,
    width: 100px
});
$('#ele_id').css({
    display: 'block'
    height: 100px,
    width: 100px
});

3.) To dynamically call on command

$('#ele_id').show();
$('#ele_id').hide();

4.) To dynamically toggle between block and none, if it's a div

• some elements are displayed as inline, inline-block, or table, depending on the Tag Name

$('#ele_id').toggle();

This is what I use, which does not need you to hardcore your resource names and will look for the drawable resources first in your apps resources and then in the stock android resources if nothing was found - allowing you to use default icons and such.

private class ImageGetter implements Html.ImageGetter {

     public Drawable getDrawable(String source) {
        int id;

        id = getResources().getIdentifier(source, "drawable", getPackageName());

        if (id == 0) {
            // the drawable resource wasn't found in our package, maybe it is a stock android drawable?
            id = getResources().getIdentifier(source, "drawable", "android");
        }

        if (id == 0) {
            // prevent a crash if the resource still can't be found
            return null;    
        }
        else {
            Drawable d = getResources().getDrawable(id);
            d.setBounds(0,0,d.getIntrinsicWidth(),d.getIntrinsicHeight());
            return d;
        }
     }

 }

Which can be used as such (example):

String myHtml = "This will display an image to the right <img src='ic_menu_more' />";
myTextview.setText(Html.fromHtml(myHtml, new ImageGetter(), null);

Since creating branches in Git is trivial you could just create a temporary branch and check the individual files into it.

The element has both an attribute and a property named checked. The property determines the current state.

The attribute is a string, and the property is a boolean. When the element is created from the HTML code, the attribute is set from the markup, and the property is set depending on the value of the attribute.

If there is no value for the attribute in the markup, the attribute becomes null, but the property is always either true or false, so it becomes false.

When you set the property, you should use a boolean value:

document.getElementById('myRadio').checked = true;

If you set the attribute, you use a string:

document.getElementById('myRadio').setAttribute('checked', 'checked');

Note that setting the attribute also changes the property, but setting the property doesn't change the attribute.

Note also that whatever value you set the attribute to, the property becomes true. Even if you use an empty string or null, setting the attribute means that it's checked. Use removeAttribute to uncheck the element using the attribute:

document.getElementById('myRadio').removeAttribute('checked');

I like using a package.json file in the root of your app folder.

Here is one I use

nvm use v0.6.4

http://pastie.org/3232212

npm install

The notation that is used in

a[::-1]

means that for a given string/list/tuple, you can slice the said object using the format

<object_name>[<start_index>, <stop_index>, <step>]

This means that the object is going to slice every "step" index from the given start index, till the stop index (excluding the stop index) and return it to you.

In case the start index or stop index is missing, it takes up the default value as the start index and stop index of the given string/list/tuple. If the step is left blank, then it takes the default value of 1 i.e it goes through each index.

So,

a = '1234'
print a[::2]

would print

13

Now the indexing here and also the step count, support negative numbers. So, if you give a -1 index, it translates to len(a)-1 index. And if you give -x as the step count, then it would step every x'th value from the start index, till the stop index in the reverse direction. For example

a = '1234'
print a[3:0:-1]

This would return

432

Note, that it doesn't return 4321 because, the stop index is not included.

Now in your case,

str(int(a[::-1]))

would just reverse a given integer, that is stored in a string, and then convert it back to a string

i.e "1234" -> "4321" -> 4321 -> "4321"

If what you are trying to do is just reverse the given string, then simply a[::-1] would work .

What would be handy would be to apply the Camera position to a new plot. So I plot, then move the plot around with the mouse changing the distance. Then try to replicate the view including the distance on another plot. I find that axx.ax.get_axes() gets me an object with the old .azim and .elev.

IN PYTHON...

axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev
dst=axx.dist       # ALWAYS GIVES 10
#dst=ax1.axes.dist # ALWAYS GIVES 10
#dst=ax1.dist      # ALWAYS GIVES 10

Later 3d graph...

ax2.view_init(elev=ele, azim=azm) #Works!
ax2.dist=dst                       # works but always 10 from axx

EDIT 1... OK, Camera position is the wrong way of thinking concerning the .dist value. It rides on top of everything as a kind of hackey scalar multiplier for the whole graph.

This works for the magnification/zoom of the view:

xlm=ax1.get_xlim3d() #These are two tupples
ylm=ax1.get_ylim3d() #we use them in the next
zlm=ax1.get_zlim3d() #graph to reproduce the magnification from mousing
axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev

Later Graph...

ax2.view_init(elev=ele, azim=azm) #Reproduce view
ax2.set_xlim3d(xlm[0],xlm[1])     #Reproduce magnification
ax2.set_ylim3d(ylm[0],ylm[1])     #...
ax2.set_zlim3d(zlm[0],zlm[1])     #...

In my case, you need to convert the column(you think this column is numeric, but actually not) to numeric

geom_segment(data=tmpp, 
   aes(x=start_pos, 
   y=lib.complexity, 
   xend=end_pos, 
   yend=lib.complexity)
)
# to 
geom_segment(data=tmpp, 
   aes(x=as.numeric(start_pos), 
   y=as.numeric(lib.complexity), 
   xend=as.numeric(end_pos), 
   yend=as.numeric(lib.complexity))
)

I think this is all you really need to do:

var listB = new List<int>{3, 4, 5};
var listA = new List<int>{1, 2, 3, 4, 5};

var listMerged = listA.Union(listB);

You can access values in the $_POST array by their key. $_POST is an associative array, so to access taskOption you would use $_POST['taskOption'];.

Make sure to check if it exists in the $_POST array before proceeding though.

<form method="post" action="process.php">
  <select name="taskOption">
    <option value="first">First</option>
    <option value="second">Second</option>
    <option value="third">Third</option>
  </select>
  <input type="submit" value="Submit the form"/>
</form>

process.php

<?php
   $option = isset($_POST['taskOption']) ? $_POST['taskOption'] : false;
   if ($option) {
      echo htmlentities($_POST['taskOption'], ENT_QUOTES, "UTF-8");
   } else {
     echo "task option is required";
     exit; 
   }

Null OR an empty string?

if (!empty($user)) {}

Use empty().

After realizing that $user ~= $_POST['user'] (thanks matt):

var uservariable='<?php 
    echo ((array_key_exists('user',$_POST)) || (!empty($_POST['user']))) ? $_POST['user'] : 'Empty Username Input';
?>';

re is powerful:

import re


def isprime(n):
    return re.compile(r'^1?$|^(11+)\1+$').match('1' * n) is None

print [x for x in range(100) if isprime(x)]

I would do this slightly different by applying both the UNPIVOT and the PIVOT functions to get the final result. The unpivot takes the values from both the totalcount and totalamount columns and places them into one column with multiple rows. You can then pivot on those results.:

select chardate,
  Australia_totalcount as [Australia # of Transactions], 
  Australia_totalamount as [Australia Total $ Amount],
  Austria_totalcount as [Austria # of Transactions], 
  Austria_totalamount as [Austria Total $ Amount]
from
(
  select 
    numericmonth, 
    chardate,
    country +'_'+col col, 
    value
  from
  (
    select numericmonth, 
      country, 
      chardate,
      cast(totalcount as numeric(10, 2)) totalcount,
      cast(totalamount as numeric(10, 2)) totalamount
    from mytransactions
  ) src
  unpivot
  (
    value
    for col in (totalcount, totalamount)
  ) unpiv
) s
pivot
(
  sum(value)
  for col in (Australia_totalcount, Australia_totalamount,
              Austria_totalcount, Austria_totalamount)
) piv
order by numericmonth

See SQL Fiddle with Demo.

If you have an unknown number of country names, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @colsName AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(country +'_'+c.col) 
                      from mytransactions
                      cross apply 
                      (
                        select 'TotalCount' col
                        union all
                        select 'TotalAmount'
                      ) c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

select @colsName 
    = STUFF((SELECT distinct ', ' + QUOTENAME(country +'_'+c.col) 
               +' as ['
               + country + case when c.col = 'TotalCount' then ' # of Transactions]' else 'Total $ Amount]' end
             from mytransactions
             cross apply 
             (

I don't there there is any DataSource for the gridview
Though you have DataBind in your code as

gvdetails.DataBind(); 

Changing Tomcat config wont effect all JVM instances to get theses settings. This is not how it works, the setting will be used only to launch JVMs used by Tomcat, not started in the shell.

Look here for permanently changing the heap size.

I had a similar issue, but had painted myself into a corner with GUI tools.

I had a subproject with a few files in it that I had so far just copied around instead of checking into their own git repo. I created a repo in the subfolder, was able to commit, push, etc just fine. But in the parent repo the subfolder wasn't treated as a submodule, and its files were still being tracked by the parent repo - no good.

To get out of this mess I had to tell Git to stop tracking the subfolder (without deleting the files):

proj> git rm -r --cached ./ui/jslib

Then I had to tell it there was a submodule there (which you can't do if anything there is currently being tracked by git):

proj> git submodule add ./ui/jslib

Update

The ideal way to handle this involves a couple more steps. Ideally, the existing repo is moved out to its own directory, free of any parent git modules, committed and pushed, and then added as a submodule like:

proj> git submodule add [email protected]:user/jslib.git ui/jslib

That will clone the git repo in as a submodule - which involves the standard cloning steps, but also several other more obscure config steps that git takes on your behalf to get that submodule to work. The most important difference is that it places a simple .git file there, instead of a .git directory, which contains a path reference to where the real git dir lives - generally at parent project root .git/modules/jslib.

If you don't do things this way they'll work fine for you, but as soon as you commit and push the parent, and another dev goes to pull that parent, you just made their life a lot harder. It will be very difficult for them to replicate the structure you have on your machine so long as you have a full .git dir in a subfolder of a dir that contains its own .git dir.

So, move, push, git add submodule, is the cleanest option.

I found a website with a "simple" tutorial: http://www.winprog.org/tutorial/start.html

Use the .Replace() method

Line.Replace("\n", "whatever you want to replace with");

There you go: (a-zA-Z)

function codeToChar( number ) {
  if ( number >= 0 && number <= 25 ) // a-z
    number = number + 97;
  else if ( number >= 26 && number <= 51 ) // A-Z
    number = number + (65-26);
  else
    return false; // range error
  return String.fromCharCode( number );
}

input: 0-51, or it will return false (range error);

OR:

var codeToChar = function() {
  var abc = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ".split("");
  return function( code ) {
    return abc[code];
  };
})();

returns undefined in case of range error. NOTE: the array will be created only once and because of closure it will be available for the the new codeToChar function. I guess it's even faster then the first method (it's just a lookup basically).

I used Adobe's detection kit, originally suggested by justpassinby. Their system is nice because it detects the version number and compares it for you against your 'required version'

One bad thing is it does an alert showing the detected version of flash, which isn't very user friendly. All of a sudden a box pops up with some seemingly random numbers.

Some modifications you might want to consider:

• remove the alert

SELECT * FROM `buckets` WHERE `bucketname` RLIKE REPLACE('stylus photo 2100', ' ', '+.*');

EDIT

Another way is to use FULLTEXT index on bucketname and MATCH ... AGAINST syntax in your SELECT statement. So to re-write the above example...

SELECT * FROM `buckets` WHERE MATCH(`bucketname`) AGAINST (REPLACE('stylus photo 2100', ' ', ','));

On Windows 10, you can enable Ctrl + C and Ctrl + V to work in the command prompt:

I think when we use onClick we want to do something different than default. So, for all your links with onClick:

$("a[onClick]").on("click", function(e) {
  return e.preventDefault();
});

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

In my case I am using tty-gem ruby gem for that.

I also needed appending, prepending (on a given text/regex inside the file), diffs, and others. The gem includes all that and a fairly clear documentation.

In React-Native we have an Option called Dimensions

Include Dimensions at the top var where you have include the Image,and Text and other components.

Then in your Stylesheets you can use as below,

ex: {
width: Dimensions.get('window').width,
height: Dimensions.get('window').height
}

In this way you can get the device window and height.

mv server.log logs/$(date -d "today" +"%Y%m%d%H%M").log

I will demonstrate the concept with code. Subclasses ACTUALLY inherit the private variables of super class. The only problem is that they are not accessible to the child objects unless you provide public getters and setters for the private variables in the super class.

Consider two class in package Dump. Child extends Parent.

If I remember correctly, a child object in memory consists of two regions. One is the parent part only and the other is the child part only. A child can access the private section in the code of its parent only via a public method in the parent.

Think of it this way. Borat's father Boltok has a safe containing $100,000. He does not want to share his "private" variable safe. So, he does not provide a key for the safe. Borat inherits the safe. But, what good is it if he cannot even open it ? If only his dad had provided the key.

Parent -

package Dump;

public class Parent {

    private String reallyHidden;
    private String notReallyHidden;

    public String getNotReallyHidden() {
        return notReallyHidden;
    }

    public void setNotReallyHidden(String notReallyHidden) {
        this.notReallyHidden = notReallyHidden;
    }

}//Parent

Child -

package Dump;

public class Child extends Parent {

    private String childOnly;

    public String getChildOnly() {
        return childOnly;
    }

    public void setChildOnly(String childOnly) {
        this.childOnly = childOnly;
    }

    public static void main(String [] args){

        System.out.println("Testing...");
        Child c1 = new Child();
        c1.setChildOnly("childOnly");
        c1.setNotReallyHidden("notReallyHidden");

        //Attempting to access parent's reallyHidden
            c1.reallyHidden;//Does not even compile

    }//main

}//Child

In one statement: No.

In one transaction: Yes

BEGIN TRANSACTION
   DECLARE @DataID int;
   INSERT INTO DataTable (Column1 ...) VALUES (....);
   SELECT @DataID = scope_identity();
   INSERT INTO LinkTable VALUES (@ObjectID, @DataID);
COMMIT

The good news is that the above code is also guaranteed to be atomic, and can be sent to the server from a client application with one sql string in a single function call as if it were one statement. You could also apply a trigger to one table to get the effect of a single insert. However, it's ultimately still two statements and you probably don't want to run the trigger for every insert.

This simple example will print 1-10 on the same line.

for i in range(1,11):
    print (i, end=" ")

Here's a couple of functions (based on Brian Bondy's example) that use WideCharToMultiByte and MultiByteToWideChar to convert between std::wstring and std::string using utf8 to not lose any data.

// Convert a wide Unicode string to an UTF8 string
std::string utf8_encode(const std::wstring &wstr)
{
    if( wstr.empty() ) return std::string();
    int size_needed = WideCharToMultiByte(CP_UTF8, 0, &wstr[0], (int)wstr.size(), NULL, 0, NULL, NULL);
    std::string strTo( size_needed, 0 );
    WideCharToMultiByte                  (CP_UTF8, 0, &wstr[0], (int)wstr.size(), &strTo[0], size_needed, NULL, NULL);
    return strTo;
}

// Convert an UTF8 string to a wide Unicode String
std::wstring utf8_decode(const std::string &str)
{
    if( str.empty() ) return std::wstring();
    int size_needed = MultiByteToWideChar(CP_UTF8, 0, &str[0], (int)str.size(), NULL, 0);
    std::wstring wstrTo( size_needed, 0 );
    MultiByteToWideChar                  (CP_UTF8, 0, &str[0], (int)str.size(), &wstrTo[0], size_needed);
    return wstrTo;
}

Put simply, an lvalue is something that can appear on the left-hand side of an assignment, typically a variable or array element.

So if you define int *p, then p is an lvalue. p+1, which is a valid expression, is not an lvalue.

If you're trying to add 1 to p, the correct syntax is:

p = p + 1;

private void loadData() {

    Scanner scanner = null;
    try {
        scanner = new Scanner(new File(getFileName()));
        while (scanner.hasNextLine()) {
            Scanner lijnScanner = new Scanner(scanner.nextLine());

            lijnScanner.useDelimiter(";");
            String stadVan = lijnScanner.next();
            String stadNaar = lijnScanner.next();
            double km = Double.parseDouble(lijnScanner.next());

            this.voegToe(new TweeSteden(stadVan, stadNaar), km);

        }
    } catch (FileNotFoundException e) {
        throw new DbException(e.getMessage(), e);
    } finally {
        if(scanner != null){
            scanner.close();
        }
    }
}

As a rule of thumb, value for non-class types and const reference for classes. If a class is really small it's probably better to pass by value, but the difference is minimal. What you really want to avoid is passing some gigantic class by value and having it all duplicated - this will make a huge difference if you're passing, say, a std::vector with quite a few elements in it.

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

Use:

var myArray = new Object();_x000D_
myArray["firstname"] = "Gareth";_x000D_

myArray["age"] = 21;_x000D_
obj = Object.keys(myArray).length;_x000D_
console.log(obj)

[x if x % 2 else x * 100 for x in range(1, 10) ]

A friend asked about using a JavaScript function to pad left. It turned into a little bit of an endeavor between some of us in chat to code golf it. This was the result:

function l(p,t,v){
    v+="";return v.length>=t?v:l(p,t,p+v); 
}

It ensures that the value to be padded is a string, and then if it isn't the length of the total desired length it will pad it once and then recurse. Here is what it looks like with more logical naming and structure

function padLeft(pad, totalLength, value){
    value = value.toString();

    if( value.length >= totalLength ){
        return value;
    }else{
        return padLeft(pad, totalLength, pad + value);
    }
}

The example we were using was to ensure that numbers were padded with 0 to the left to make a max length of 6. Here is an example set:

function l(p,t,v){v+="";return v.length>=t?v:l(p,t,p+v);}_x000D_
_x000D_
var vals = [6451,123,466750];_x000D_
_x000D_
var pad = l(0,6,vals[0]);// pad with 0's, max length 6_x000D_
_x000D_
var pads = vals.map(function(i){ return l(0,6,i) });_x000D_
_x000D_
document.write(pads.join("<br />"));

Add your php folder path to the System PATH and everything should work fine. It will also fix some other extensions that are broken.

"/tmp/test.jpg" is not the correct path – this path starts with / which is the root directory.

In unix, the shortcut to the current directory is .

Try this "./tmp/test.jpg"

While matt b's answer will work, you can also use .serializeArray() to get an array from the form data, modify it, and use jQuery.param() to convert it to a url-encoded form. This way, jQuery handles the serialisation of your extra data for you.

var data = $(this).serializeArray(); // convert form to array
data.push({name: "NonFormValue", value: NonFormValue});
$.ajax({
    type: 'POST',
    url: this.action,
    data: $.param(data),
});

I just tried with PHP 5.2, and that constant seems to exists :

var_dump(PDO::MYSQL_ATTR_INIT_COMMAND);

Gives me :

int 1002

But it seems there is a bug in PHP 5.3, that causes this constant to not exists anymore -- or, at least, not when the mysqlnd driver is used (and it's the one that's configured by default)

I suppose a temporary solution, as suggested on this bug report, could be to directly use the integer 1002 value, instead of the contant...

But note that you should go back to using the constant as soon as possible -- as this makes the code easier to understand.

label, input {
    vertical-align: middle;
}

I'm just align the vertical midpoint of the boxes with the baseline of the parent box plus half the x-height (en.wikipedia.org/wiki/X-height) of the parent.

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

Below is a slightly awkward solution for the special case in which you are creating the original file yourself and happen to know the insertion location (e.g. you know ahead of time that you will need to insert a line with an additional name before the third line, but won't know the name until after you've fetched and written the rest of the names). Reading, storing and then re-writing the entire contents of the file as described in other answers is, I think, more elegant than this option, but may be undesirable for large files.

You can leave a buffer of invisible null characters ('\0') at the insertion location to be overwritten later:

num_names = 1_000_000    # Enough data to make storing in a list unideal
max_len = 20             # The maximum allowed length of the inserted line
line_to_insert = 2       # The third line is at index 2 (0-based indexing)

with open(filename, 'w+') as file:
    for i in range(line_to_insert):
        name = get_name(i)                    # Returns 'Alfred' for i = 0, etc.
        file.write(F'{i + 1}. {name}\n')

    insert_position = file.tell()             # Position to jump back to for insertion
    file.write('\0' * max_len + '\n')         # Buffer will show up as a blank line

    for i in range(line_to_insert, num_names):
        name = get_name(i)
        file.write(F'{i + 2}. {name}\n')      # Line numbering now bumped up by 1.

# Later, once you have the name to insert...
with open(filename, 'r+') as file:            # Must use 'r+' to write to middle of file 
    file.seek(insert_position)                # Move stream to the insertion line
    name = get_bonus_name()                   # This lucky winner jumps up to 3rd place
    new_line = F'{line_to_insert + 1}. {name}'
    file.write(new_line[:max_len])            # Slice so you don't overwrite next line

Unfortunately there is no way to delete-without-replacement any excess null characters that did not get overwritten (or in general any characters anywhere in the middle of a file), unless you then re-write everything that follows. But the null characters will not affect how your file looks to a human (they have zero width).

Besides changing it to Console (/SUBSYSTEM:CONSOLE) as others have said, you may need to change the entry point in Properties -> Linker -> Advanced -> Entry Point. Set it to mainCRTStartup.

It seems that Visual Studio might be searching for the WinMain function instead of main, if you don't specify otherwise.

The entire section of the switch is a single declaration context. You can't declare a variable in a case statement like that. Try this instead:

switch (val)  
{  
case VAL:
{
  // This will work
  int newVal = 42;
  break;
}
case ANOTHER_VAL:  
  ...
  break;
}

If you want, you can deactivate this feature in your git core config using

git config core.autocrlf false

But it would be better to just get rid of the warnings using

git config core.autocrlf true

var top = event.target.offsetTop + 'px';

Use the modulo operator:

if wordLength % 2 == 0:
    print "wordLength is even"
else:
    print "wordLength is odd"

For your problem, the simplest is to check if the word is equal to its reversed brother. You can do that with word[::-1], which create the list from word by taking every character from the end to the start:

def is_palindrome(word):
    return word == word[::-1]

The steps mentioned by Jason are very good and should work. There is a little twist with SQL Developer, though. It caches the connection specifications (host, service name, port) the first time it reads the tnsnames.ora file. Then, it does not invalidate the specs when the original entry is removed from the tnsname.ora file. The cache persists even after SQL Developer has been terminated and restarted. This is not such an illogical way of handling the situation. Even if a tnsnames.ora file is temporarily unavailable, SQL Developer can still make the connection as long as the original specifications are still true. The problem comes with their next little twist. SQL Developer treats service names in the tnsnames.ora file as case-sensitive values when resolving the connection. So if you used to have an entry name ABCD.world in the file and you replaced it with an new entry named abcd.world, SQL Developer would NOT update its connection specs for ABCD.world - it will treat abcd.world as a different connection altogether. Why am I not surprised that an Oracle product would treat as case-sensitive the contents of an oracle-developed file format that is expressly case-insensitive?

If you need to take grapheme clusters into account, use regexp or unicode module. Counting the number of code points(runes) or bytes also is needed for validaiton since the length of grapheme cluster is unlimited. If you want to eliminate extremely long sequences, check if the sequences conform to stream-safe text format.

package main

import (
    "regexp"
    "unicode"
    "strings"
)

func main() {

    str := "\u0308" + "a\u0308" + "o\u0308" + "u\u0308"
    str2 := "a" + strings.Repeat("\u0308", 1000)

    println(4 == GraphemeCountInString(str))
    println(4 == GraphemeCountInString2(str))

    println(1 == GraphemeCountInString(str2))
    println(1 == GraphemeCountInString2(str2))

    println(true == IsStreamSafeString(str))
    println(false == IsStreamSafeString(str2))
}


func GraphemeCountInString(str string) int {
    re := regexp.MustCompile("\\PM\\pM*|.")
    return len(re.FindAllString(str, -1))
}

func GraphemeCountInString2(str string) int {

    length := 0
    checked := false
    index := 0

    for _, c := range str {

        if !unicode.Is(unicode.M, c) {
            length++

            if checked == false {
                checked = true
            }

        } else if checked == false {
            length++
        }

        index++
    }

    return length
}

func IsStreamSafeString(str string) bool {
    re := regexp.MustCompile("\\PM\\pM{30,}") 
    return !re.MatchString(str) 
}

copied from: https://android.stackexchange.com/questions/12962/flush-clear-dns-cache

Addresses are cached for 600 seconds (10 minutes) by default. Failed lookups are cached for 10 seconds. From everything I've seen, there's nothing built in to flush the cache. This is apparently a reported bug http://code.google.com/p/android/issues/detail?id=7904 in Android because of the way it stores DNS cache. Clearing the browser cache doesn't touch the DNS, the "hard reset" clears it.

I am using WebCalendar and found that Mac iCal barfs on importing a generated ics file because the end-of-line is hardcoded in xcal.php as "\r\n". I went in and replaced all occurrences with PHP_EOL and now iCal is happy! I also tested it on Vista and Outlook was able to import the file as well, even though the end of line character is "\n".

Set decoding to true

Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.

$WorkingArray = json_decode(json_encode($data),true);

Take a look at LinkedHashSet class

From Java doc:

Hash table and linked list implementation of the Set interface, with predictable iteration order. This implementation differs from HashSet in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is the order in which elements were inserted into the set (insertion-order). Note that insertion order is not affected if an element is re-inserted into the set. (An element e is reinserted into a set s if s.add(e) is invoked when s.contains(e) would return true immediately prior to the invocation.).

To add to Alex Kucherenko solution: the issue with the cursor getting disappearing after calling setInputType(0) is due to a framework bug on ICS (and JB).

The bug is documented here: https://code.google.com/p/android/issues/detail?id=27609.

To workaround this, call setRawInputType(InputType.TYPE_CLASS_TEXT) right after the setInputType call.

To stop the keyboard from appearing, just override OnTouchListener of the EditText and return true (swallowing the touch event):

ed.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                return true;
            }
        });

The reasons for the cursor appearing on GB devices and not on ICS+ had me tearing my hair out for a couple of hours, so I hope this saves someone's time.

It must work. I used to debug a .exe file and a dll at the same time ! What I suggest is 1) Include the path of the dll in your B project, 2) Then compile in debug your A project 3) Control that the path points on the A dll and de pdb file.... 4)After that you start in debug the B project and if all is ok, you will be able to debug in both projects !

PHP code on how I'm returning data to this jquery ajax call in autocomplete:

/**

  static function getProductList() {
        $name   = CRM_Utils_Array::value( 's', $_GET );
    $name   = CRM_Utils_Type::escape( $name, 'String' );
    $limit  = '10';

        $strSearch = "description LIKE '%$name%'";

        $subCategory   = CRM_Utils_Array::value( 'subCategory', $_GET );
    $subCategory   = CRM_Utils_Type::escape( $subCategory, 'String' );

        if (!empty($subCategory))

Probably you need an array?

var Game = {

    status: [
        ["val", "val","val"],
        ["val", "val", "val"]
    ]
}

alert(Game.status[0][0]);

According to String class documentation they are equivalent.

Documentation for String(String original) also says that: Unless an explicit copy of original is needed, use of this constructor is unnecessary since Strings are immutable.

Look for other responses, because it seems that Java documentation is misleading :(

Constants can't be changed, static variables have more to do with how they are allocated and where they are accessible.

Check out this site.

You can use an inline if inside your ngStyle:

[ngStyle]="styleOne?{'background-color': 'red'} : {'background-color': 'blue'}"

A batter way in my opinion is to store your background color inside a variable and then set the background-color as the variable value:

[style.background-color]="myColorVaraible"

I had the same question but applying the provided solutions changed the file to write in. Once I selected the new excel file, I was also writing in that file and not in my original file. My solution for this issue is below:

Sub GetData()

    Dim excelapp As Application
    Dim source As Workbook
    Dim srcSH1 As Worksheet
    Dim sh As Worksheet
    Dim path As String
    Dim nmr As Long
    Dim i As Long

    nmr = 20

    Set excelapp = New Application

    With Application.FileDialog(msoFileDialogOpen)
        .AllowMultiSelect = False
        .Filters.Add "Excel Files", "*.xlsx; *.xlsm; *.xls; *.xlsb", 1
        .Show
        path = .SelectedItems.Item(1)
    End With

    Set source = excelapp.Workbooks.Open(path)
    Set srcSH1 = source.Worksheets("Sheet1")
    Set sh = Sheets("Sheet1")

    For i = 1 To nmr
        sh.Cells(i, "A").Value = srcSH1.Cells(i, "A").Value
    Next i

End Sub

With excelapp a new application will be called. The with block sets the path for the external file. Finally, I set the external Workbook with source and srcSH1 as a Worksheet within the external sheet.

This has to do with having two buttons with the same ID in two different Activities, sometimes Android Studio can't find, You just have to give your button a new ID and re Build the Project

A -exec command must be terminated with a ; (so you usually need to type \; or ';' to avoid interpretion by the shell) or a +. The difference is that with ;, the command is called once per file, with +, it is called just as few times as possible (usually once, but there is a maximum length for a command line, so it might be split up) with all filenames. See this example:

$ cat /tmp/echoargs
#!/bin/sh
echo $1 - $2 - $3
$ find /tmp/foo -exec /tmp/echoargs {} \;
/tmp/foo - -
/tmp/foo/one - -
/tmp/foo/two - -
$ find /tmp/foo -exec /tmp/echoargs {} +
/tmp/foo - /tmp/foo/one - /tmp/foo/two

Your command has two errors:

First, you use {};, but the ; must be a parameter of its own.

Second, the command ends at the &&. You specified “run find, and if that was successful, remove the file named {};.“. If you want to use shell stuff in the -exec command, you need to explicitly run it in a shell, such as -exec sh -c 'ffmpeg ... && rm'.

However you should not add the {} inside the bash command, it will produce problems when there are special characters. Instead, you can pass additional parameters to the shell after -c command_string (see man sh):

$ ls
$(echo damn.)
$ find * -exec sh -c 'echo "{}"' \;
damn.
$ find * -exec sh -c 'echo "$1"' - {} \;
$(echo damn.)

You see the $ thing is evaluated by the shell in the first example. Imagine there was a file called $(rm -rf /) :-)

(Side note: The - is not needed, but the first variable after the command is assigned to the variable $0, which is a special variable normally containing the name of the program being run and setting that to a parameter is a little unclean, though it won't cause any harm here probably, so we set that to just - and start with $1.)

So your command could be something like

find -exec bash -c 'ffmpeg -i "$1" -sameq "$1".mp3 && rm "$1".mp3' - {} \;

But there is a better way. find supports and and or, so you may do stuff like find -name foo -or -name bar. But that also works with -exec, which evaluates to true if the command exits successfully, and to false if not. See this example:

$ ls
false  true
$ find * -exec {} \; -and -print
true

It only runs the print if the command was successfully, which it did for true but not for false.

So you can use two exec statements chained with an -and, and it will only execute the latter if the former was run successfully.

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

This works for me:

try {
       $statusUpdate = $facebook->api('/me/feed', 'post',
                 array('name'=>'My APP on Facebook','message'=> 'I am here working',
                 'privacy'=> array('value'=>'CUSTOM','friends'=>'SELF'),
                 'description'=>'testing my description',
                 'picture'=>'https://fbcdn-photos-a.akamaihd.net/mypicture.gif',
                 'caption'=>'apps.facebook.com/myapp','link'=>'http://apps.facebook.com/myapp'));
 } catch (FacebookApiException $e) {
      d($e);
}

Request.ServerVariables["REMOTE_ADDR"] should work - either directly in a view or in the controller action method body (Request is a property of Controller class in MVC, not Page).

It is working.. but you have to publish on a real IIS not the virtual one.

according to @jreback here https://github.com/conda/conda/issues/1166

conda config --set ssl_verify false 

will turn off this feature, e.g. here

I've created a small plugin (available on NuGet) that allows you to add any (if supported by your terminal) color to your console output, without the limitations of the classic solutions.

It works by extending the String object and the syntax is very simple:

"colorize me".Pastel("#1E90FF");

Both foreground and background colors are supported.

As Matt has said, use Console.Write. I would also recommend explicitly flushing the output, however - I believe WriteLine does this automatically, but I'd seen oddities when just using Console.Write and then waiting. So Matt's code becomes:

Console.Write("What is your name? ");
Console.Out.Flush();
var name = Console.ReadLine();

I had a similar issue when deploying from OSx on my local to my Linux live site.

It ran fine on OSx, but on Linux I was getting:

An Error Was Encountered

Unable to load the requested class: Ckeditor

The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".

I also changed my load call to match the capitalization:

$this->load->library('CKEditor');

from your question I assume that you already have your data in hdfs. So you don't need to LOAD DATA, which moves the files to the default hive location /user/hive/warehouse. You can simply define the table using the externalkeyword, which leaves the files in place, but creates the table definition in the hive metastore. See here: Create Table DDL eg.:

create external table table_name (
  id int,
  myfields string
)
location '/my/location/in/hdfs';

Please note that the format you use might differ from the default (as mentioned by JigneshRawal in the comments). You can use your own delimiter, for example when using Sqoop:

row format delimited fields terminated by ','

I've found yet an easier way to write to a Zebra printer over a COM port. I went to the Windows control panel and added a new printer. For the port, I chose COM1 (the port the printer was plugged in to). I used a "Generic / Text Only" printer driver. I disabled the print spooler (a standard option in the printer preferences) as well as all advanced printing options. Now, I can just print any string to that printer and if the string contains ZPL, the printer renders the ZPL just fine! No need for special "start sequences" or funky stuff like that. Yay for simplicity!

After Stop xampp, go to configure and change the port 3306 to 3308 of mysql and save. Now start the sql......Enjoy

Many browsers have changed their security policies to no longer allow reading data directly from file shares or even local resources. You need to either place the files somewhere that your tomcat instance can serve them up and put a "regular" http url in the html you generate. This can be accomplished by either providing a servlet which reads and provides the file putting the file into a directory where tomcat will serve it up as "static" content.

If you were looking for what to use in android, it is:

String android.text.TextUtils.join(CharSequence delimiter, Object[] tokens)

for example:

String joined = TextUtils.join(";", MyStringArray);

I wrote a module called Ng-Idle that may be useful to you in this situation. Here is the page which contains instructions and a demo.

Basically, it has a service that starts a timer for your idle duration that can be disrupted by user activity (events, such as clicking, scrolling, typing). You can also manually interrupt the timeout by calling a method on the service. If the timeout is not disrupted, then it counts down a warning where you could alert the user they are going to be logged out. If they do not respond after the warning countdown reaches 0, an event is broadcasted that your application can respond to. In your case, it could issue a request to kill their session and redirect to a login page.

Additionally, it has a keep-alive service that can ping some URL at an interval. This can be used by your app to keep a user's session alive while they are active. The idle service by default integrates with the keep-alive service, suspending the pinging if they become idle, and resuming it when they return.

All the info you need to get started is on the site with more details in the wiki. However, here's a snippet of config showing how to sign them out when they time out.

angular.module('demo', ['ngIdle'])
// omitted for brevity
.config(function(IdleProvider, KeepaliveProvider) {
  IdleProvider.idle(10*60); // 10 minutes idle
  IdleProvider.timeout(30); // after 30 seconds idle, time the user out
  KeepaliveProvider.interval(5*60); // 5 minute keep-alive ping
})
.run(function($rootScope) {
    $rootScope.$on('IdleTimeout', function() {
        // end their session and redirect to login
    });
});

Ok, here's a simple example using curb.

require 'yaml'
require 'curb'

# prepare post data
post_data = fields_hash.map { |k, v| Curl::PostField.content(k, v.to_s) }
post_data << Curl::PostField.file('file', '/path/to/file'), 

# post
c = Curl::Easy.new('http://localhost:3000/foo')
c.multipart_form_post = true
c.http_post(post_data)

# print response
y [c.response_code, c.body_str]

Note: I don't know the correct answer, but the below is just my personal speculation!

As has been mentioned a 0 before a number means it's octal:

04524 // octal, leading 0

Imagine needing to come up with a system to denote hexadecimal numbers, and note we're working in a C style environment. How about ending with h like assembly? Unfortunately you can't - it would allow you to make tokens which are valid identifiers (eg. you could name a variable the same thing) which would make for some nasty ambiguities.

8000h // hex
FF00h // oops - valid identifier!  Hex or a variable or type named FF00h?

You can't lead with a character for the same reason:

xFF00 // also valid identifier

Using a hash was probably thrown out because it conflicts with the preprocessor:

#define ...
#FF00 // invalid preprocessor token?

In the end, for whatever reason, they decided to put an x after a leading 0 to denote hexadecimal. It is unambiguous since it still starts with a number character so can't be a valid identifier, and is probably based off the octal convention of a leading 0.

0xFF00 // definitely not an identifier!

valign="top" should do the work.

<tr>_x000D_
  <td valign="top">Description</td>_x000D_
</tr>

Using json lib:-

String data="[{"A":"a","B":"b","C":"c","D":"d","E":"e","F":"f","G":"g"}]";
Object object=null;
JSONArray arrayObj=null;
JSONParser jsonParser=new JSONParser();
object=jsonParser.parse(data);
arrayObj=(JSONArray) object;
System.out.println("Json object :: "+arrayObj);

Using GSON lib:-

Gson gson = new Gson();
String data="[{\"A\":\"a\",\"B\":\"b\",\"C\":\"c\",\"D\":\"d\",\"E\":\"e\",\"F\":\"f\",\"G\":\"g\"}]";
JsonParser jsonParser = new JsonParser();
JsonArray jsonArray = (JsonArray) jsonParser.parse(data);

Building on Jeff's answer, your first step would be to create a canvas representation of your PNG. The following creates an off-screen canvas that is the same width and height as your image and has the image drawn on it.

var img = document.getElementById('my-image');
var canvas = document.createElement('canvas');
canvas.width = img.width;
canvas.height = img.height;
canvas.getContext('2d').drawImage(img, 0, 0, img.width, img.height);

After that, when a user clicks, use event.offsetX and event.offsetY to get the position. This can then be used to acquire the pixel:

var pixelData = canvas.getContext('2d').getImageData(event.offsetX, event.offsetY, 1, 1).data;

Because you are only grabbing one pixel, pixelData is a four entry array containing the pixel's R, G, B, and A values. For alpha, anything less than 255 represents some level of transparency with 0 being fully transparent.

Here is a jsFiddle example: http://jsfiddle.net/thirtydot/9SEMf/869/ I used jQuery for convenience in all of this, but it is by no means required.

Note: getImageData falls under the browser's same-origin policy to prevent data leaks, meaning this technique will fail if you dirty the canvas with an image from another domain or (I believe, but some browsers may have solved this) SVG from any domain. This protects against cases where a site serves up a custom image asset for a logged in user and an attacker wants to read the image to get information. You can solve the problem by either serving the image from the same server or implementing Cross-origin resource sharing.

You neglected to say which version of C you are concerned about. Let's assume it's this one:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf

As you can see by reading the specification, the standard definitions of true and false are 1 and 0, yes.

If your question is about a different version of C, or about non-standard definitions for true and false, then ask a more specific question.

Using the .mjs extension (as suggested in the accepted answer) in order to enable ECMAScript modules works. However, with Node.js v12, you can also enable this feature globally in your package.json file.

The official documentation states:

import statements of .js and extensionless files are treated as ES modules if the nearest parent package.json contains "type": "module".

{
  "type": "module",
  "main": "./src/index.js"
}

(Of course you still have to provide the flag --experimental-modules when starting your application.)
