An instance method applies to an instance of the class (i.e. an object) whereas a class method applies to the class itself.

In C# a class method is marked static. Methods and properties not marked static are instance methods.

class Foo {
  public static void ClassMethod() { ... }
  public void InstanceMethod() { ... }
}

From my code, comparing to above solution, the simplest way is to define a layout which contains the fragment, then you could hide or unhide the fragment by controlling the layout attribute which is align with the general way of view. No additional code needed in this case and the additional deployment attributes of the fragment could be moved to the outer layout.

<LinearLayout style="@style/StHorizontalLinearView"
    >

    <fragment
        android:layout_width="match_parent"
        android:layout_height="390dp"
        android:layout_alignParentTop="true"
        />

</LinearLayout>

Use this when if satisfies

do

return true;

Tuple classes allow developers to be 'quick and lazy' by not defining a specific class for a specific use.

The property names are Item1, Item2, Item3 ..., which may not be meaningful in some cases or without documentation.

Tuple classes have strongly typed generic parameters. Still users of the Tuple classes may infer from the type of generic parameters.

To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

For MacOS without installing PostgreSQL server:

brew install libpq
gem install pg -- --with-pg-config="/usr/local/Cellar/libpq/9.6.6/bin/pg_config"

Eaven if you are going to prevent sql injection front-end, using html or js checks, you'd have to consider that front-end checks are "bypassable".

You can disable js or edit a pattern with a front-end development tool (built in with firefox or chrome nowadays).

So, in order to prevent SQL injection, would be right to sanitize input date backend inside your controller.

I would like to suggest to you to use filter_input() native PHP function in order to sanitize GET and INPUT values.

If you want to go ahead with security, for sensible database queries, I'd like to suggest to you to use regular expression to validate data format. preg_match() will help you in this case! But take care! Regex engine is not so light. Use it only if necessary, otherwise your application performances will decrease.

Security has a costs, but do not waste your performance!

Easy example:

if you want to double check if a value, received from GET is a number, less then 99 if(!preg_match('/[0-9]{1,2}/')){...} is heavyer of

if (isset($value) && intval($value)) <99) {...}

So, the final answer is: "No! PDO Prepared Statements does not prevent all kind of sql injection"; It does not prevent unexpected values, just unexpected concatenation

For anyone else who came here looking to do the same with docker-compose you just need to prepend bash -c and enclose multiple commands in quotes, joined together with &&.

So in the OPs example docker-compose run image bash -c "cd /path/to/somewhere && python a.py"

Use std::string and find.

std::string str = "/user/desktop/abc/post/";
bool exists = str.find("/abc/") != std::string::npos;

Basically React.useState(0) magically sees that it should return the tuple count and setCount (a method to change count). The parameter useState takes sets the initial value of count.

  const [count, setCount] = React.useState(0);
  const [count2, setCount2] = React.useState(0);

  // increments count by 1 when first button clicked
  function handleClick(){
    setCount(count + 1);
  } 

  // increments count2 by 1 when second button clicked
  function handleClick2(){
    setCount2(count2 + 1);
  } 

  return (
    <div>
      <h2>A React counter made with the useState Hook!</h2>
      <p>You clicked {count} times</p>
      <p>You clicked {count2} times</p>
      <button onClick={handleClick}>
        Click me
      </button> 
      <button onClick={handleClick2}>
        Click me2
      </button>
  );

Based off Enmanuel Duran's example, but shows two counters and writes lambda functions as normal functions, so some people might understand it easier.

You should NOT use jQuery('selector').attr("tagName").toLowerCase(), because it only works in older versions of Jquery.

You could use $('selector').prop("tagName").toLowerCase() if you're certain that you're using a version of jQuery thats >= version 1.6.

Note :

You may think that EVERYONE is using jQuery 1.10+ or something by now (January 2016), but unfortunately that isn't really the case. For example, many people today are still using Drupal 7, and every official release of Drupal 7 to this day includes jQuery 1.4.4 by default.

So if do not know for certain if your project will be using jQuery 1.6+, consider using one of the options that work for ALL versions of jQuery :

Option 1 :

jQuery('selector')[0].tagName.toLowerCase()

Option 2

jQuery('selector')[0].nodeName.toLowerCase()

The reason why Ng-Bind is better because,

When Your page is not Loaded or when your internet is slow or when your website loaded half, then you can see these type of issues (Check the Screen Shot with Read mark) will be triggered on Screen which is Completly weird. To avoid such we should use Ng-bind

I replace Jasmine's toThrow matcher with the following, which lets you match on the exception's name property or its message property. For me this makes tests easier to write and less brittle, as I can do the following:

throw {
   name: "NoActionProvided",
   message: "Please specify an 'action' property when configuring the action map."
}

and then test with the following:

expect (function () {
   .. do something
}).toThrow ("NoActionProvided");

This lets me tweak the exception message later without breaking tests, when the important thing is that it threw the expected type of exception.

This is the replacement for toThrow that allows this:

jasmine.Matchers.prototype.toThrow = function(expected) {
  var result = false;
  var exception;
  if (typeof this.actual != 'function') {
    throw new Error('Actual is not a function');
  }
  try {
    this.actual();
  } catch (e) {
    exception = e;
  }
  if (exception) {
      result = (expected === jasmine.undefined || this.env.equals_(exception.message || exception, expected.message || expected) || this.env.equals_(exception.name, expected));
  }

  var not = this.isNot ? "not " : "";

  this.message = function() {
    if (exception && (expected === jasmine.undefined || !this.env.equals_(exception.message || exception, expected.message || expected))) {
      return ["Expected function " + not + "to throw", expected ? expected.name || expected.message || expected : " an exception", ", but it threw", exception.name || exception.message || exception].join(' ');
    } else {
      return "Expected function to throw an exception.";
    }
  };

  return result;
};

As the name suggests, snapshot refers to a state of project and its dependencies at that moment of time. Whenever maven finds a newer SNAPSHOT of the project, it downloads and replaces the older .jar file of the project in the local repository.

Snapshot versions are used for projects under active development. If your project depends on a software component that is under active development, you can depend on a snapshot release, and Maven will periodically attempt to download the latest snapshot from a repository when you run a build.

You'll like this, change it so that it can suit your requirements.

mkdir today
Copy Desktop\test1\*.* today
setlocal enableextensions
set name=%DATE:/=_%
Rename "today" _OlddatabaseBackup_"%name%"

I also get the same error in an ASP.NET application when I saved some unicode data (Hindi) in the Web.config file and saved it with "Unicode" encoding.

It fixed the error for me when I saved the Web.config file with "UTF-8" encoding.

Suggestions:

• Create a File object that refers to the already existing file on disk.
• Use a FileWriter object, and use the constructor that takes the File object and a boolean, the latter if true would allow appending text into the File if it exists.
• Then initialize a PrintWriter passing in the FileWriter into its constructor.
• Then call println(...) on your PrintWriter, writing your new text into the file.
• As always, close your resources (the PrintWriter) when you are done with it.
• As always, don't ignore exceptions but rather catch and handle them.
• The close() of the PrintWriter should be in the try's finally block.

e.g.,

  PrintWriter pw = null;

  try {
     File file = new File("fubars.txt");
     FileWriter fw = new FileWriter(file, true);
     pw = new PrintWriter(fw);
     pw.println("Fubars rule!");
  } catch (IOException e) {
     e.printStackTrace();
  } finally {
     if (pw != null) {
        pw.close();
     }
  }

Easy, no?

If anyone else comes across this, I'm adding another answer to provide the response code or other information that might be needed in the "response".

http://php.net/manual/en/function.curl-getinfo.php

// init curl object        
$ch = curl_init();

// define options
$optArray = array(
    CURLOPT_URL => 'http://www.google.com',
    CURLOPT_RETURNTRANSFER => true
);

// apply those options
curl_setopt_array($ch, $optArray);

// execute request and get response
$result = curl_exec($ch);

// also get the error and response code
$errors = curl_error($ch);
$response = curl_getinfo($ch, CURLINFO_HTTP_CODE);

curl_close($ch);

var_dump($errors);
var_dump($response);

Output:

string(0) ""
int(200)

// change www.google.com to www.googlebofus.co
string(42) "Could not resolve host: www.googlebofus.co"
int(0)

Use a JSON parser. There are plenty of JSON parsers written in Java.

Look under the Java section and find one you like.

For just copying (possibly long) texts to the Windows clipboard, I have found that just piping the output to clip.exe (including the .exe file extension) works fine for me. So:

$ echo "Hello World" | clip.exe

lets me paste Hello World using Ctrl-V anywhere else.

Now that I have posted this, I notice that related question Pipe from clipboard in linux subsytem for windows includes this and a command solution for pasting from the Windows clipboard as well.

This error occurs when you compile a java program using classes that support the Servlet API. The compiler searches for the library (included in a .jar file) by using the CLASSPATH. You can specify this when you compile using -classpath or -cp options as noted in other responses, but you should set up your environment to define the classpath as needed.

Set the CLASSPATH environment variable to reference the location of servlet-api.jar, which depends on your setup (OS, how you installed, etc.)

Assuming you're using Tomcat and have installed it in one of 20 possible ways, the APIs used by servlets will be installed on your system, relative to wherever Tomcat is installed. For historical reasons, Tomcat is also known as "Catalina", so you can use the command "catalina" to run certain commands, and alone, it will report, amongst other things the CATALINA_BASE. For example on my Mac using Tomcat installed using homebrew it's

Using CATALINA_BASE:   /usr/local/Cellar/tomcat/8.5.9/libexec

The location of the Tomcat servlet libraries is under this in the lib directory. Set CATALINA_BASE, then set CLASSPATH using the base as a start, for example for Linux or OSX you might set this in .profile, or .bash_profile like so:

export CATALINA_BASE=/usr/local/Cellar/tomcat/8.5.9/libexec
export CLASSPATH=$CATALINA_BASE/lib/servlet-api.jar:$CLASSPATH

Exit the terminal/shell and come back in to run the profile. You should be able to see that the variable is set by using the echo command, e.g.

echo $CLASSPATH

or in Windows

echo %CLASSPATH%

If it displays the full path to the jar `javac WebTest.java' compile your class.

Other answers are correct -- set up your IDE (Eclipse, IntelliJ) to know about Tomcat or build with Maven and you'll save pain.

I think a lot of people know about pointers in C but are not sure if it works in C#. You can use pointers in C# in an unsafe context:

static void Main()
{
    int i;
    unsafe
    {               
        // pointer pi has the address of variable i
        int* pi = &i; 
        // pointer ppi has the address of variable pi
        int** ppi = π
        // ppi(addess of pi) -> pi(addess of i) -> i(0)
        i = 0;
        // dereference the pi, i.e. *pi is i
        Console.WriteLine("i = {0}", *pi); // output: i = 0
        // since *pi is i, equivalent to i++
        (*pi)++;
        Console.WriteLine("i = {0}", *pi); // output: i = 1
        // since *ppi is pi, one more dereference  *pi is i 
        // equivalent to i += 2
        **ppi += 2;
        Console.WriteLine("i = {0}", *pi);// output: i = 3
    }
    Console.ReadLine();
}

As @user207421 say there is no way to know the current state of the connection because of the TCP/IP Protocol Architecture Model. So the server has to notice you before closing the connection or you check it by yourself.
This is a simple example that shows how to know the socket is closed by the server:

sockAdr = new InetSocketAddress(SERVER_HOSTNAME, SERVER_PORT);
socket = new Socket();
timeout = 5000;
socket.connect(sockAdr, timeout);
reader = new BufferedReader(new InputStreamReader(socket.getInputStream());
while ((data = reader.readLine())!=null) 
      log.e(TAG, "received -> " + data);
log.e(TAG, "Socket closed !");

Ok to answer this . I simply converted my < and the > to < and >. What was happening previously is i used to set the text <script>alert('1')</script> but before setting the text in the input text browserconverts < and > as < and the >. So hence converting them again to < and >since browser will understand that as only tags and converts them , than executing the script inside <input type="text" />

The best practice is definitely to avoid loops or recursions in Matlab.

Between sum(A(:)) and sum(sum(A)). In my experience, arrays in Matlab seems to be stored in a continuous block in memory as stacked column vectors. So the shape of A does not quite matter in sum(). (One can test reshape() and check if reshaping is fast in Matlab. If it is, then we have a reason to believe that the shape of an array is not directly related to the way the data is stored and manipulated.)

As such, there is no reason sum(sum(A)) should be faster. It would be slower if Matlab actually creates a row vector recording the sum of each column of A first and then sum over the columns. But I think sum(sum(A)) is very wide-spread amongst users. It is likely that they hard-code sum(sum(A)) to be a single loop, the same to sum(A(:)).

Below I offer some testing results. In each test, A=rand(size) and size is specified in the displayed texts.

In my experience, both timers are only meaningful up to .1s. So if you have similar experience with Matlab timers, none of the tests can discern sum(A(:)) and sum(sum(A)).

They seem equivalent. Either one is good. But sum(sum(A)) requires that you know the dimension of your array is 2.

If you're using Python 2.5 or later, the uuid module is already included with the Python standard distribution.

Ex:

>>> import uuid
>>> uuid.uuid4()
UUID('5361a11b-615c-42bf-9bdb-e2c3790ada14')

For .NET 3.5 and lower you could use:

string.Format ("{0:00}:{1:00}:{2:00}", 
               (int)myTimeSpan.TotalHours, 
                    myTimeSpan.Minutes, 
                    myTimeSpan.Seconds);

Code taken from a Jon Skeet answer on bytes

For .NET 4.0 and above, see DoctaJonez answer.

If you want just a rough estimate, you can extrapolate from a sample:

SELECT COUNT(*) * 100 FROM sometable SAMPLE (1);

For greater speed (but lower accuracy) you can reduce the sample size:

SELECT COUNT(*) * 1000 FROM sometable SAMPLE (0.1);

For even greater speed (but even worse accuracy) you can use block-wise sampling:

SELECT COUNT(*) * 100 FROM sometable SAMPLE BLOCK (1);

Besides the redundant ) this expression will always be true because currentStatus will always match one of these two conditions:

currentStatus !== 'open' || currentStatus !== 'reopen'

perhaps you mean one of

!(currentStatus === 'open' || currentStatus === 'reopen')
(currentStatus !== 'open' && currentStatus !== 'reopen')

You could try a combination of the waitfor and rasterize examples:

/**

 * on a server response or for a ui change (fadeIn, etc.) to occur.
 *
 * @param testFx javascript condition that evaluates to a boolean,

 * as a callback function.
 * @param onReady what to do when testFx condition is fulfilled,
 * it can be passed in as a string (e.g.: "1 == 1" or "$('#bar').is(':visible')" or
 * as a callback function.
 * @param timeOutMillis the max amount of time to wait. If not specified, 3 sec is used.
 */

Or you can use this neat little function, because why overcomplicated solutions?

function getQueryParam(param, defaultValue = undefined) {
    location.search.substr(1)
        .split("&")
        .some(function(item) { // returns first occurence and stops
            return item.split("=")[0] == param && (defaultValue = item.split("=")[1], true)
        })
    return defaultValue
}

which looks even better when simplified and onelined:

tl;dr one-line solution

var queryDict = {};
location.search.substr(1).split("&").forEach(function(item) {queryDict[item.split("=")[0]] = item.split("=")[1]})

result:
queryDict['sent'] // undefined or 'value'

But what if you have got encoded characters or multivalued keys?

You better see this answer: How can I get query string values in JavaScript?

Maybe we can create a function to do what João proposed? Something like:

def cursor_exec(cursor, query, params):
    expansion_params= []
    real_params = []
    for p in params:
       if isinstance(p, (tuple, list)):
         real_params.extend(p)
         expansion_params.append( ("%s,"*len(p))[:-1] )
       else:
         real_params.append(p)
         expansion_params.append("%s")
    real_query = query % expansion_params
    cursor.execute(real_query, real_params)

I had the same problem and which got resolved by using ./ before the directory name in my node.js app, i.e.

app.use(express.static('./public'));

So hopefully this helps someone out.

The new answer that Reuben Scratton gave is great and really efficient, but it really only works if you set your windowSoftInputMode to adjustResize. If you set it to adjustPan, it's still not possible to detect whether or not the keyboard is visible using his code snippet. To work around this, I made this tiny modification to the code above.

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
    Rect r = new Rect();
    //r will be populated with the coordinates of your view that area still visible.
    activityRootView.getWindowVisibleDisplayFrame(r);
   
    int heightDiff = activityRootView.getRootView().getHeight() - r.height();
    if (heightDiff > 0.25*activityRootView.getRootView().getHeight()) { // if more than 25% of the screen, its probably a keyboard...
        ... do something here
    }
 }
}); 

@DougW has clearly answered this question, but I still like to add some codes here to explain Doug's points. (And correct errors in the code above)

Solution 1: URL-encode the POST data with a content-type header :application/x-www-form-urlencoded .

Note: you do not need to urlencode $_POST[] fields one by one, http_build_query() function can do the urlencoding job nicely.

$fields = array(
    'mediaupload'=>$file_field,
    'username'=>$_POST["username"],
    'password'=>$_POST["password"],
    'latitude'=>$_POST["latitude"],
    'longitude'=>$_POST["longitude"],
    'datetime'=>$_POST["datetime"],
    'category'=>$_POST["category"],
    'metacategory'=>$_POST["metacategory"],
    'caption'=>$_POST["description"]
);

$fields_string = http_build_query($fields);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

Solution 2: Pass the array directly as the post data without URL-encoding, while the Content-Type header will be set to multipart/form-data.

$fields = array(
        'mediaupload'=>$file_field,
        'username'=>$_POST["username"],
        'password'=>$_POST["password"],
        'latitude'=>$_POST["latitude"],
        'longitude'=>$_POST["longitude"],
        'datetime'=>$_POST["datetime"],
        'category'=>$_POST["category"],
        'metacategory'=>$_POST["metacategory"],
        'caption'=>$_POST["description"]
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);

Both code snippets work, but using different HTTP headers and bodies.

With Groovy, you don't need the includes, and can just do:

String oldDate = '04-DEC-2012'
Date date = Date.parse( 'dd-MMM-yyyy', oldDate )
String newDate = date.format( 'M-d-yyyy' )

println newDate

To print:

12-4-2012

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

I have adopted your script for my situation Jotne.

#! /bin/bash

logfile="/var/oscamlog/oscam1check.log"

case "$(pidof oscam1 | wc -w)" in

0)  echo "oscam1 not running, restarting oscam1:     $(date)" >> $logfile
    /usr/local/bin/oscam1 -b -c /usr/local/etc/oscam1 -t /usr/local/tmp.oscam1 &
    ;;
2)  echo "oscam1 running, all OK:     $(date)" >> $logfile
    ;;
*)  echo "multiple instances of oscam1 running. Stopping & restarting oscam1:     $(date)" >> $logfile
    kill $(pidof oscam1 | awk '{print $1}')
    ;;
esac

While I was testing, I ran into a problem.. I started 3 extra process's of oscam1 with this line: /usr/local/bin/oscam1 -b -c /usr/local/etc/oscam1 -t /usr/local/tmp.oscam1 which left me with 8 process for oscam1. the problem is this.. When I run the script, It only kills 2 process's at a time, so I would have to run it 3 times to get it down to 2 process..

Other than killall -9 oscam1 followed by /usr/local/bin/oscam1 -b -c /usr/local/etc/oscam1 -t /usr/local/tmp.oscam1, in *)is there any better way to killall apart from the original process? So there would be zero downtime?

With jQuery:

$('form').submit(function () {
    // Validate here

    if (pass)
        return true;
    else
        return false;
});

No need jquery for this

I used this to center Div element. Css Style,

.black_overlay{
    display: none;
    position: absolute;
    top: 0%;
    left: 0%;
    width: 100%;
    height: 100%;
    background-color: black;
    z-index:1001;
    -moz-opacity: 0.8;
    opacity:.80;
    filter: alpha(opacity=80);
}

.white_content {
    display: none;
    position: absolute;
    top: 25%;
    left: 25%;
    width: 50%;
    height: 50%;
    padding: 16px;
    border: 16px solid orange;
    background-color: white;
    z-index:1002;
    overflow: auto;
}

Open element

$(document).ready(function(){
    $(".open").click(function(e){
      $(".black_overlay").fadeIn(200);
    });

});

I'd submit another possible solution in Ruby. Looks like it's the be smallest and cleanest looking one so far:

A=2003-12-11
B=2002-10-10
DIFF=$(ruby -rdate -e "puts Date.parse('$A') - Date.parse('$B')")
echo $DIFF

See Class Constants:

class MyClass
{
    const MYCONSTANT = 'constant value';

    function showConstant() {
        echo  self::MYCONSTANT. "\n";
    }
}

echo MyClass::MYCONSTANT. "\n";

$classname = "MyClass";
echo $classname::MYCONSTANT. "\n"; // As of PHP 5.3.0

$class = new MyClass();
$class->showConstant();

echo $class::MYCONSTANT."\n"; // As of PHP 5.3.0

In this case echoing MYCONSTANT by itself would raise a notice about an undefined constant and output the constant name converted to a string: "MYCONSTANT".

EDIT - Perhaps what you're looking for is this static properties / variables:

class MyClass
{
    private static $staticVariable = null;

    public static function showStaticVariable($value = null)
    {
        if ((is_null(self::$staticVariable) === true) && (isset($value) === true))
        {
            self::$staticVariable = $value;
        }

        return self::$staticVariable;
    }
}

MyClass::showStaticVariable(); // null
MyClass::showStaticVariable('constant value'); // "constant value"
MyClass::showStaticVariable('other constant value?'); // "constant value"
MyClass::showStaticVariable(); // "constant value"

When using jQuery in asp.net, if you are using a master page and you are loading the jquery source file there, make sure you have the header contentplaceholder after all the jquery script references.

I had a problem where any pages that used that master page would return '$ is not defined' simply because the incorrect order was making the client side code run before the jquery object was created. So make sure you have:

<head runat="server">
    <script type="text/javascript" src="Scripts/jquery-VERSION#.js"></script>
    <asp:ContentPlaceHolder id="Header" runat="server"></asp:ContentPlaceHolder>
</head>

That way the code will run in order and you will be able to run jQuery code on the child pages.

GUI Option:

1. Open System Properties

   a. Type it in the Start Menu

   b. Use the keyboard shortcut Win+Pause)

   c. From Windows Explorer address bar go to

   %windir%\System32\SystemPropertiesProtection.exe

   d. Write SystemPropertiesProtection in run window and press Enter

2. Switch to the Advanced tab

3. Click Environment Variables
4. Select PATH in the System variables section
5. Click Edit
6. Add python's path to the end of the list (the paths are separated by semicolons).

For example:

C:\Windows;C:\Windows\System32;C:\Python27

Command Line Option:

1. Run Command Prompt as administrator

2. Check existing paths under PATH variable (the paths are separated by semicolons). If your python folder already listed then no need to add again. Default python folder is C:\Python27

   C:\Windows\system32>path or C:\Windows\system32>echo %PATH%

3. Append python path using setx command. The /M option sets the variable at SYSTEM scope.

The default behavior is to set it for the USER.

C:\Windows\system32>setx /M PATH "%PATH%;C:\Python27"

First give your input type submit a name, like this name='submitform'.

and then put this in your php file

if (isset($_POST['submitform']))
    {   
    ?>
<script type="text/javascript">
window.location = "http://www.google.com/";
</script>      
    <?php
    }

Don't forget to change the url to yours.

As suggested you can use JAD to decompile it and view the files. To make it easier to read you can use the JADclipse plugin for eclipse to integrate JAD directly to eclipse or use DJ Java Decompiler which is much easier to use than command line JAD

Try this

<input name="selector[]" id="ad_Checkbox1" class="ads_Checkbox" type="checkbox" value="1" />
<input name="selector[]" id="ad_Checkbox2" class="ads_Checkbox" type="checkbox" value="2" />
<input name="selector[]" id="ad_Checkbox3" class="ads_Checkbox" type="checkbox" value="3" />
<input name="selector[]" id="ad_Checkbox4" class="ads_Checkbox" type="checkbox" value="4" />
<input type="button" id="save_value" name="save_value" value="Save" />

function

    $(function(){
      $('#save_value').click(function(){
        var val = [];
        $(':checkbox:checked').each(function(i){
          val[i] = $(this).val();
        });
      });
    });

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

I know its quite late to answer this, but I guess it will help anyone ahead.

Well using CSS3 FlexBox. It can be acheived. Make you header as display:flex and divide its entire width into 3 parts. In the first part I have placed the logo, the searchbar in second part and buttons container in last part. apply justify-content: between to the header container and flex-grow:1 to the searchbar. That's it. The sample code is below.

#header {_x000D_
  background-color: #323C3E;_x000D_
  justify-content: space-between;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
#searchBar, img{_x000D_
  align-self: center;_x000D_
}_x000D_
_x000D_
#searchBar{_x000D_
  flex-grow:1;_x000D_
  background-color: orange;_x000D_
  padding: 10px;_x000D_
}_x000D_
_x000D_
#searchBar input {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
.button {_x000D_
  padding: 22px;_x000D_
}_x000D_
_x000D_
.buttonsHolder{_x000D_
  display:flex;_x000D_
}

<div id="header" class="d-flex justify-content-between">_x000D_
    <img src="img/logo.png" />_x000D_
    <div id="searchBar">_x000D_
      <input type="text" />_x000D_
    </div>_x000D_
    <div class="buttonsHolder">_x000D_
      <div class="button orange inline" id="myAccount">_x000D_
        My Account_x000D_

If you can use .NET 4 or higher than use HasFlag() method

examples

letter.HasFlag(Letters.A | Letters.B) // both A and B must be set

same as

letter.HasFlag(Letters.AB)

What you're looking for is called a "reverse merge". You should consult the docs regarding the merge function in the SVN book (as luapyad, or more precisely the first commenter on that post, points out). If you're using Tortoise, you can also just go into the log view and right-click and choose "revert changes from this revision" on the one where you made the mistake.

Try this for WPF

StreamResourceInfo sri = Application.GetResourceStream(new Uri("pack://application:,,,/WpfGifImage001;Component/Images/Progess_Green.gif"));
picBox1.Image = System.Drawing.Image.FromStream(sri.Stream);

suppose you want to write a url to fetch some order, you can say

www.mydomain.com/order/123

where 123 is orderId.

So now the url you will use in spring mvc controller would look like

/order/{orderId}

Now order id can be declared a path variable

@RequestMapping(value = " /order/{orderId}", method=RequestMethod.GET)
public String getOrder(@PathVariable String orderId){
//fetch order
}

if you use url www.mydomain.com/order/123, then orderId variable will be populated by value 123 by spring

Also note that PathVariable differs from requestParam as pathVariable is part of URL. The same url using request param would look like www.mydomain.com/order?orderId=123

The simplest solution in general form:

def get_subclasses(cls):
    for subclass in cls.__subclasses__():
        yield from get_subclasses(subclass)
        yield subclass

And a classmethod in case you have a single class where you inherit from:

@classmethod
def get_subclasses(cls):
    for subclass in cls.__subclasses__():
        yield from subclass.get_subclasses()
        yield subclass

Using windows authentication:

From the Spring reference, 3.2.3.1 Naming Beans:

Every bean has one or more ids (also called identifiers, or names; these terms refer to the same thing). These ids must be unique within the container the bean is hosted in. A bean will almost always have only one id, but if a bean has more than one id, the extra ones can essentially be considered aliases.

When using XML-based configuration metadata, you use the 'id' or 'name' attributes to specify the bean identifier(s). The 'id' attribute allows you to specify exactly one id, and as it is a real XML element ID attribute, the XML parser is able to do some extra validation when other elements reference the id; as such, it is the preferred way to specify a bean id. However, the XML specification does limit the characters which are legal in XML IDs. This is usually not a constraint, but if you have a need to use one of these special XML characters, or want to introduce other aliases to the bean, you may also or instead specify one or more bean ids, separated by a comma (,), semicolon (;), or whitespace in the 'name' attribute.

So basically the id attribute conforms to the XML id attribute standards whereas name is a little more flexible. Generally speaking, I use name pretty much exclusively. It just seems more "Spring-y".

Create Method like this :

//CHANGE ICON COLOR
private void changeIconColor(Context context ,int drawable){
    Drawable unwrappedDrawable = AppCompatResources.getDrawable(context, drawable);
    assert unwrappedDrawable != null;
    Drawable wrappedDrawable = DrawableCompat.wrap(unwrappedDrawable);
    DrawableCompat.setTint(wrappedDrawable, getResources().getColor(R.color.colorAccent));
}

and use it like it :

    changeIconColor(this,R.drawable.ic_home);

Go to 'c:/Windows/System32' and delete the java.exe, javaw.exe and javaws.exe there. See at Registry Key '...' has value '1.7', but '1.6' is required. Java 1.7 is Installed and the Registry is Pointing to it

"Access violation reading location 0x00000000" means that you're derefrencing a pointer that hasn't been initialized and therefore has garbage values. Those garbage values could be anything, but usually it happens to be 0 and so you try to read from the memory address 0x0, which the operating system detects and prevents you from doing.

Check and make sure that the array invaders[] is what you think it should be.

Also, you don't seem to be updating i ever - meaning that you keep placing the same Invader object into location 0 of invaders[] at every loop iteration.

I had a similar issue with the iteration and I landed here. Maybe someone else is also doing the same mistake I did.

In my case, the selector was not the problem at all. The problem was that I had messed up the javascript code: I had a loop and a subloop. The subloop was also using i as a counter, instead of j, so because the subloop was overriding the value of i of the main loop, this one never got to the second iteration.

var dayContainers = document.getElementsByClassName('day-container');
for(var i = 0; i < dayContainers.length; i++) { //loop of length = 2
        var thisDayDiv = dayContainers[i];
        // do whatever

        var inputs = thisDayDiv.getElementsByTagName('input');

        for(var j = 0; j < inputs.length; j++) { //loop of length = 4
            var thisInput = inputs[j];
            // do whatever

        };

    };

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.

Convert a JSON string into an object in C#. Using below test case.. its worked for me. Here "MenuInfo" is my C# class object.

JsonTextReader reader = null;
try
{
    WebClient webClient = new WebClient();
    JObject result = JObject.Parse(webClient.DownloadString("YOUR URL"));
    reader = new JsonTextReader(new System.IO.StringReader(result.ToString()));
    reader.SupportMultipleContent = true;
}

{}

JsonSerializer serializer = new JsonSerializer();
MenuInfo menuInfo = serializer.Deserialize<MenuInfo>(reader);

Try $.param

$.post("page.php",( $('#myForm').serialize()+'&'+$.param({ 'wordlist': wordlist })));

But it really is "I don\u2018t like this" and not "I don't like this". The character u'\u2018' is a completely different character than "'" (and, visually, should correspond more to '`').

If you're trying to convert encoded unicode into plain ASCII, you could perhaps keep a mapping of unicode punctuation that you would like to translate into ASCII.

punctuation = {
  u'\u2018': "'",
  u'\u2019': "'",
}
for src, dest in punctuation.iteritems():
  text = text.replace(src, dest)

There are an awful lot of punctuation characters in unicode, however, but I suppose you can count on only a few of them actually being used by whatever application is creating the documents you're reading.

This kind of code perhaps should work for You

I would add this as a comment to the other good answers, but I need more reputation to do so. Be sure to allow for scientific notation if necessary, i.e. 3e4 = 30000. This is default behavior in many languages. I found the following regex to work:

/^[-+]?\d+([Ee][+-]?\d+)?$/;
//          ^^              If 'e' is present to denote exp notation, get it
//             ^^^^^          along with optional sign of exponent
//                  ^^^       and the exponent itself
//        ^            ^^     The entire exponent expression is optional

Try to convertValue by Jackson

ObjectMapper mapper = new ObjectMapper()
Integer a = 1;
Long b = mapper.convertValue(a, Long.class)

host just includes the port number if there is one specified. If there is no port number specifically in the URL, then it returns the same as hostname. You pick whether you care to match the port number or not. See https://developer.mozilla.org/en/window.location for more info.

I would assume you want hostname to just get the site name.

YUI has a testing framework as well. This video from Yahoo! Theater is a nice introduction, although there are a lot of basics about TDD up front.

This framework is generic and can be run against any JavaScript or JS library.

I use getActionCommand() to hear buttons. I apply the setActionCommand() to each button so that I can hear whenever an event is execute with event.getActionCommand("The setActionCommand() value of the button").

I use getSource() for JRadioButtons for example. I write methods that returns each JRadioButton so in my Listener Class I can specify an action each time a new JRadioButton is pressed. So for example:

public class SeleccionListener implements ActionListener, FocusListener {}

So with this I can hear button events and radioButtons events. The following are examples of how I listen each one:

public void actionPerformed(ActionEvent event) {
    if (event.getActionCommand().equals(GUISeleccion.BOTON_ACEPTAR)) {
        System.out.println("Aceptar pressed");
    }

In this case GUISeleccion.BOTON_ACEPTAR is a "public static final String" which is used in JButtonAceptar.setActionCommand(BOTON_ACEPTAR).

public void focusGained(FocusEvent focusEvent) {
    if (focusEvent.getSource().equals(guiSeleccion.getJrbDat())){
        System.out.println("Data radio button");
    }

In this one, I get the source of any JRadioButton that is focused when the user hits it. guiSeleccion.getJrbDat() returns the reference to the JRadioButton that is in the class GUISeleccion (this is a Frame)

Using .NET 4.5 trying to perform form POST file upload. Tried most of the methods above but to no avail. Found the solution here https://www.c-sharpcorner.com/article/upload-any-file-using-http-post-multipart-form-data

But I am not not keen as I do not understand why we still need to deal with such low level programming in these common usages (should be handled nicely by framework)

How is this possible? Without an index on the er101_upd_date_iso column how can a clustered index scan be used?

An index is a B-Tree where each leaf node is pointing to a 'bunch of rows'(called a 'Page' in SQL internal terminology), That is when the index is a non-clustered index.

Clustered index is a special case, in which the leaf nodes has the 'bunch of rows' (rather than pointing to them). that is why...

1) There can be only one clustered index on the table.

this also means the whole table is stored as the clustered index, that is why you started seeing index scan rather than a table scan.

2) An operation that utilizes clustered index is generally faster than a non-clustered index

Read more at http://msdn.microsoft.com/en-us/library/ms177443.aspx

For the problem you have, you should really consider adding this column to a index, as you said adding a new index (or a column to an existing index) increases INSERT/UPDATE costs. But it might be possible to remove some underutilized index (or a column from an existing index) to replace with 'er101_upd_date_iso'.

If index changes are not possible, i recommend adding a statistics on the column, it can fasten things up when the columns have some correlation with indexed columns

http://msdn.microsoft.com/en-us/library/ms188038.aspx

BTW, You will get much more help if you can post the table schema of ER101_ACCT_ORDER_DTL. and the existing indices too..., probably the query could be re-written to use some of them.

This also works - In the link HTML use onclick with return like this :

<a href="mypage.html" onclick="return confirmClick();">Delete</a>

And then the comfirmClick() function should be like:

function confirmClick() {
    if(confirm("Do you really want to delete this task?")) {
        return true;
    } else {
        return false;
    }
};

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

I use this function as a parameter to the PHP filter_var function.

• It checks for dates in yyyy-mm-dd hh:mm:ss format
• It rejects dates that match the pattern but still invalid (e.g. Apr 31)

function filter_mydate($s) {
    if (preg_match('@^(\d\d\d\d)-(\d\d)-(\d\d) (\d\d):(\d\d):(\d\d)$@', $s, $m) == false) {
        return false;
    }
    if (checkdate($m[2], $m[3], $m[1]) == false || $m[4] >= 24 || $m[5] >= 60 || $m[6] >= 60) {
        return false;
    }
    return $s;
}

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

vector<string> getseq(char * db_file)

And if you want to print it on main() you should do it in a loop.

int main() {
     vector<string> str_vec = getseq(argv[1]);
     for(vector<string>::iterator it = str_vec.begin(); it != str_vec.end(); it++) {
         cout << *it << endl;
     }
}

Can't comment because I don't have enough reputation points, but recode only works on a vector, so the above code in @Stefano's answer should be

df <- iris %>%
  mutate(Species = recode(Species, 
     setosa = "SETOSA",
     versicolor = "VERSICOLOR",
     virginica = "VIRGINICA")
  )

I am a little late for the show but in case the above answer didn't solve the query then I found another way. Simply remove the specific large file from .pack. I had this issue where I checked in a large 2GB file accidentally. I followed the steps explained in this link: http://www.ducea.com/2012/02/07/howto-completely-remove-a-file-from-git-history/

I don't know why it does not work for Html.EditorFor but I tried TextBoxFor and it worked for me.

@Html.TextBoxFor(m => m.Name, new { Class = "className", Size = "40"})

...and also validation works.

Simple way in Java

public void resize(String inputImagePath,
            String outputImagePath, int scaledWidth, int scaledHeight)
            throws IOException {
        // reads input image
        File inputFile = new File(inputImagePath);
        BufferedImage inputImage = ImageIO.read(inputFile);
 
        // creates output image
        BufferedImage outputImage = new BufferedImage(scaledWidth,
                scaledHeight, inputImage.getType());
 
        // scales the input image to the output image
        Graphics2D g2d = outputImage.createGraphics();
        g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
        g2d.dispose();
 
        // extracts extension of output file
        String formatName = outputImagePath.substring(outputImagePath
                .lastIndexOf(".") + 1);
 
        // writes to output file
        ImageIO.write(outputImage, formatName, new File(outputImagePath));
    }

If you forgot to add the repository HTTPS link then put it with git push <repo HTTPS>

Specifically: ((depth)). By example, the following prints 1.

declare -i x=0
((x)) && echo $x

x=1
((x)) && echo $x

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

code that works, but output is:

10
20
30
40
50

so:

    List<Integer> myCoords = new ArrayList<Integer>();
    myCoords.add(10);
    myCoords.add(20);
    myCoords.add(30);
    myCoords.add(40);
    myCoords.add(50);
    for (Integer number : myCoords) {
        System.out.println(number);
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

Generate a hash, maybe with a secret only you know, then store it in your DB so it can be associated with the user. Should work quite well.

It was due to IE Document-mode version too low. Press 'F12' and using higher version( My case, above version 9 is OK)

You can use a MultiBinding combined with the StringFormat property. Usage would resemble the following:

<TextBlock>
    <TextBlock.Text>    
        <MultiBinding StringFormat="{}{0} + {1}">
            <Binding Path="Name" />
            <Binding Path="ID" />
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

Giving Name a value of Foo and ID a value of 1, your output in the TextBlock would then be Foo + 1.

Note: that this is only supported in .NET 3.5 SP1 and 3.0 SP2 or later.

Simple way to iterate over class fields and obtain values from object:

 Class<?> c = obj.getClass();
 Field[] fields = c.getDeclaredFields();
 Map<String, Object> temp = new HashMap<String, Object>();

 for( Field field : fields ){
      try {
           temp.put(field.getName().toString(), field.get(obj));
      } catch (IllegalArgumentException e1) {
      } catch (IllegalAccessException e1) {
      }
 }

First of all you need to understand that final output of both the statements will be same i.e. to remove all the spaces from given string.

However x.replaceAll("\\s+", ""); will be more efficient way of trimming spaces (if string can have multiple contiguous spaces) because of potentially less no of replacements due the to fact that regex \\s+ matches 1 or more spaces at once and replaces them with empty string.

So even though you get the same output from both it is better to use:

x.replaceAll("\\s+", "");

For me, using margin:15px;padding:10px 0 15px 23px;width:100%, the result was this:

The solution for me was to use width:auto instead of width:100%. My new code was:

margin:15px;padding:10px 0 15px 23px;width:auto. Then the element aligned properly:

You can access the form over the event:

e.target.reset();

If you're not too attached to your current workspace you can create a new workspace, follow BalusC's steps for server creation, and recreate your project in the new workspace.

I got the same error after installing Eclipse Java EE IDE for Web Developers(Juno) but using the workspace of a much older Eclipse installation. When I created a new workspace I was able to get my Tomcat server running without this error.

Both do the same on all browsers, AFAIK. Checked on Chrome and Firefox, both append display:none to the style attribute of the element.

select P.*,
A.Street,
A.City,
A.State
from Preson P
inner join Address A on P.id=A.Person_id
where A.Zip=97229
Order by A.Street,A.City,A.State

No there isn't. You can only read information associated with the current domain.

You can use this :

@GET("group/{id}/users")

Call<List<User>> groupList(@Path("id") int groupId, @Query("sort") String sort);

I thought there were a few perfectly fine answers, but no concise summary of all possibilities; thus:

The core principal behind most answers here is redirection. Two are important redirection operators for writing to files:

Redirecting Output:

echo 'text to completely overwrite contents of myfile' > myfile

Appending Redirected Output

echo 'text to add to end of myfile' >> myfile

Here Documents

Others mentioned, rather than from a fixed input source like echo 'text', you could also interactively write to files via a "Here Document", which are also detailed in the link to the bash manual above. Those answers, e.g.

cat > FILE.txt <<EOF or cat >> FILE.txt <<EOF

make use of the same redirection operators, but add another layer via "Here Documents". In the above syntax, you write to the FILE.txt via the output of cat. The writing only takes place after the interactive input is given some specific string, in this case 'EOF', but this could be any string, e.g.:

cat > FILE.txt <<'StopEverything' or cat >> FILE.txt <<'StopEverything'

would work just as well. Here Documents also look for various delimiters and other interesting parsing characters, so have a look at the docs for further info on that.

Here Strings

A bit convoluted, and more of an exercise in understanding both redirection and Here Documents syntax, but you could combine Here Document style syntax with standard redirect operators to become a Here String:

cat > myfile <<<'text to completely overwrite contents of myfile'

cat >> myfile <<<'text to completely overwrite contents of myfile'

Did you forget to join some tables? If not then you probably need to use some aliases.

This can be done in two ways.

JLabel Horizontal Alignment

You can use the JLabel constructor:

JLabel(String text, int horizontalAlignment) 

To align to the right:

JLabel label = new JLabel("Telephone", SwingConstants.RIGHT);

JLabel also has setHorizontalAlignment:

label.setHorizontalAlignment(SwingConstants.RIGHT);

This assumes the component takes up the whole width in the container.

Using Layout

A different approach is to use the layout to actually align the component to the right, whilst ensuring they do not take the whole width. Here is an example with BoxLayout:

    Box box = Box.createVerticalBox();
    JLabel label1 = new JLabel("test1, the beginning");
    label1.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label1);

    JLabel label2 = new JLabel("test2, some more");
    label2.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label2);

    JLabel label3 = new JLabel("test3");
    label3.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label3);


    add(box);

I've updated Eric D's answer for Swift 5:

 func convertStringToDictionary(text: String) -> [String:AnyObject]? {
    if let data = text.data(using: .utf8) {
        do {
            let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String:AnyObject]
            return json
        } catch {
            print("Something went wrong")
        }
    }
    return nil
}

One option is strtok

example:

char name[20];
//pretend name is set to the value "My name"

You want to split it at the space between the two words

split=strtok(name," ");

while(split != NULL)
{
    word=split;
    split=strtok(NULL," ");
}

You can call up the color picker from any Cocoa application (TextEdit, Mail, Keynote, Pages, etc.) by hitting Shift-Command-C

The following article explains more about using Mac OS's Color Picker.

http://www.macworld.com/article/46746/2005/09/colorpickersecrets.html

Use the -ss option:

ffmpeg -ss 01:23:45 -i input -vframes 1 -q:v 2 output.jpg

• For JPEG output use -q:v to control output quality. Full range is a linear scale of 1-31 where a lower value results in a higher quality. 2-5 is a good range to try.

• The select filter provides an alternative method for more complex needs such as selecting only certain frame types, or 1 per 100, etc.

• Placing -ss before the input will be faster. See FFmpeg Wiki: Seeking and this excerpt from the ffmpeg cli tool documentation:

-ss position (input/output)

When used as an input option (before -i), seeks in this input file to position. Note the in most formats it is not possible to seek exactly, so ffmpeg will seek to the closest seek point before position. When transcoding and -accurate_seek is enabled (the default), this extra segment between the seek point and position will be decoded and discarded. When doing stream copy or when -noaccurate_seek is used, it will be preserved.

When used as an output option (before an output filename), decodes but discards input until the timestamps reach position.

position may be either in seconds or in hh:mm:ss[.xxx] form.

If you want to get a feel for FRP, you could start with the old Fran tutorial from 1998, which has animated illustrations. For papers, start with Functional Reactive Animation and then follow up on links on the publications link on my home page and the FRP link on the Haskell wiki.

Personally, I like to think about what FRP means before addressing how it might be implemented. (Code without a specification is an answer without a question and thus "not even wrong".) So I don't describe FRP in representation/implementation terms as Thomas K does in another answer (graphs, nodes, edges, firing, execution, etc). There are many possible implementation styles, but no implementation says what FRP is.

I do resonate with Laurence G's simple description that FRP is about "datatypes that represent a value 'over time' ". Conventional imperative programming captures these dynamic values only indirectly, through state and mutations. The complete history (past, present, future) has no first class representation. Moreover, only discretely evolving values can be (indirectly) captured, since the imperative paradigm is temporally discrete. In contrast, FRP captures these evolving values directly and has no difficulty with continuously evolving values.

FRP is also unusual in that it is concurrent without running afoul of the theoretical & pragmatic rats' nest that plagues imperative concurrency. Semantically, FRP's concurrency is fine-grained, determinate, and continuous. (I'm talking about meaning, not implementation. An implementation may or may not involve concurrency or parallelism.) Semantic determinacy is very important for reasoning, both rigorous and informal. While concurrency adds enormous complexity to imperative programming (due to nondeterministic interleaving), it is effortless in FRP.

So, what is FRP? You could have invented it yourself. Start with these ideas:

• Dynamic/evolving values (i.e., values "over time") are first class values in themselves. You can define them and combine them, pass them into & out of functions. I called these things "behaviors".

• Behaviors are built up out of a few primitives, like constant (static) behaviors and time (like a clock), and then with sequential and parallel combination. n behaviors are combined by applying an n-ary function (on static values), "point-wise", i.e., continuously over time.

• To account for discrete phenomena, have another type (family) of "events", each of which has a stream (finite or infinite) of occurrences. Each occurrence has an associated time and value.

• To come up with the compositional vocabulary out of which all behaviors and events can be built, play with some examples. Keep deconstructing into pieces that are more general/simple.

• So that you know you're on solid ground, give the whole model a compositional foundation, using the technique of denotational semantics, which just means that (a) each type has a corresponding simple & precise mathematical type of "meanings", and (b) each primitive and operator has a simple & precise meaning as a function of the meanings of the constituents. Never, ever mix implementation considerations into your exploration process. If this description is gibberish to you, consult (a) Denotational design with type class morphisms, (b) Push-pull functional reactive programming (ignoring the implementation bits), and (c) the Denotational Semantics Haskell wikibooks page. Beware that denotational semantics has two parts, from its two founders Christopher Strachey and Dana Scott: the easier & more useful Strachey part and the harder and less useful (for software design) Scott part.

If you stick with these principles, I expect you'll get something more-or-less in the spirit of FRP.

Where did I get these principles? In software design, I always ask the same question: "what does it mean?". Denotational semantics gave me a precise framework for this question, and one that fits my aesthetics (unlike operational or axiomatic semantics, both of which leave me unsatisfied). So I asked myself what is behavior? I soon realized that the temporally discrete nature of imperative computation is an accommodation to a particular style of machine, rather than a natural description of behavior itself. The simplest precise description of behavior I can think of is simply "function of (continuous) time", so that's my model. Delightfully, this model handles continuous, deterministic concurrency with ease and grace.

It's been quite a challenge to implement this model correctly and efficiently, but that's another story.

Use @Named to differentiate between different objects of the same type bound in the same scope.

@Named("maxWaitTime")
public long maxWaitTimeMs;

@Named("minWaitTime")
public long minWaitTimeMs;

Without the @Named qualifier, the injector would not know which long to bind to which variable.

• If you want to create annotations that act like @Named, use the @Qualifier annotation when creating them.

• If you look at @Named, it is itself annotated with @Qualifier.

$ readlink -m FILE
/path/to/FILE

This is better than readlink -e FILE or realpath, because it works even if the file doesn't exist.

There's a more appropriate way than asking the viewControllers. You can make your controller a delegate of the navigationBar that has the back button. Here's an example. In the implementation of the controller where you want to handle the press of the back button, tell it that it will implement the UINavigationBarDelegate protocol:

@interface MyViewController () <UINavigationBarDelegate>

Then somewhere in your initialization code (probably in viewDidLoad) make your controller the delegate of its navigation bar:

self.navigationController.navigationBar.delegate = self;

Finally, implement the shouldPopItem method. This method gets called right when the back button is pressed. If you have multiple controllers or navigation Items in the stack, you'll probably want to check which of those navigation items is getting popped (the item parameter), so that you only do your custom stuff when you expect to. Here's an example:

-(BOOL)navigationBar:(UINavigationBar *)navigationBar shouldPopItem:(UINavigationItem *)item
{
    NSLog(@"Back button got pressed!");
    //if you return NO, the back button press is cancelled
    return YES;
}

Update 2020

Products are located mainly in the following tables:

• wp_posts table with post_type like product (or product_variation),

• wp_postmeta table with post_id as relational index (the product ID).

• wp_wc_product_meta_lookup table with product_id as relational index (the post ID) | Allow fast queries on specific product data (since WooCommerce 3.7)

• wp_wc_order_product_lookuptable with product_id as relational index (the post ID) | Allow fast queries to retrieve products on orders (since WooCommerce 3.7)

Product types, categories, subcategories, tags, attributes and all other custom taxonomies are located in the following tables:

• wp_terms

• wp_termmeta

• wp_term_taxonomy

• wp_term_relationships - column object_id as relational index (the product ID)

• wp_woocommerce_termmeta

• wp_woocommerce_attribute_taxonomies (for product attributes only)

• wp_wc_category_lookup (for product categories hierarchy only since WooCommerce 3.7)

Product types are handled by custom taxonomy product_type with the following default terms:

• simple
• grouped
• variable
• external

Some other product types for Subscriptions and Bookings plugins:

• subscription
• variable-subscription
• booking

Since Woocommerce 3+ a new custom taxonomy named product_visibility handle:

• The product visibility with the terms exclude-from-search and exclude-from-catalog
• The feature products with the term featured
• The stock status with the term outofstock
• The rating system with terms from rated-1 to rated-5

Particular feature: Each product attribute is a custom taxonomy…

According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.

Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.

Is your problem similar to this:

l = [[0]] * 4
l[0][0] += 1
print l # prints "[[1], [1], [1], [1]]"

If so, you simply need to copy the objects when you store them:

import copy
l = [copy.copy(x) for x in [[0]] * 4]
l[0][0] += 1
print l # prints "[[1], [0], [0], [0]]"

The objects in question should implement a __copy__ method to copy objects. See the documentation for copy. You may also be interested in copy.deepcopy, which is there as well.

EDIT: Here's the problem:

arrayList = []
for x in allValues:
    result = model(x)
    arrayList.append(wM) # appends the wM object to the list
    wM.reset()           # clears  the wM object

You need to append a copy:

import copy
arrayList = []
for x in allValues:
    result = model(x)
    arrayList.append(copy.copy(wM)) # appends a copy to the list
    wM.reset()                      # clears the wM object

But I'm still confused as to where wM is coming from. Won't you just be copying the same wM object over and over, except clearing it after the first time so all the rest will be empty? Or does model() modify the wM (which sounds like a terrible design flaw to me)? And why are you throwing away result?

You can commit some updated files, like this:

git commit file1 file2 file5 -m "commit message"

The simple answer is to turn off async. But that's the wrong thing to do. The correct answer is to re-think how you write the rest of your code.

Instead of writing this:

function functABC(){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        success: function(data) {
            return data;
        }
    });
}

function foo () {
    var response = functABC();
    some_result = bar(response);
    // and other stuff and
    return some_result;
}

You should write it like this:

function functABC(callback){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        success: callback
    });
}

function foo (callback) {
    functABC(function(data){
        var response = data;
        some_result = bar(response);
        // and other stuff and
        callback(some_result);
    })
}

That is, instead of returning result, pass in code of what needs to be done as callbacks. As I've shown, callbacks can be nested to as many levels as you have function calls.

A quick explanation of why I say it's wrong to turn off async:

Turning off async will freeze the browser while waiting for the ajax call. The user cannot click on anything, cannot scroll and in the worst case, if the user is low on memory, sometimes when the user drags the window off the screen and drags it in again he will see empty spaces because the browser is frozen and cannot redraw. For single threaded browsers like IE7 it's even worse: all websites freeze! Users who experience this may think you site is buggy. If you really don't want to do it asynchronously then just do your processing in the back end and refresh the whole page. It would at least feel not buggy.

*X*YZ* = string contains X and contains YZ

@".*X.*YZ"

X*YZ*P = string starts with X, contains YZ and ends with P.

try creating connection string this way:

MySqlConnectionStringBuilder conn_string = new MySqlConnectionStringBuilder();
conn_string.Server = "mysql7.000webhost.com";
conn_string.UserID = "a455555_test";
conn_string.Password = "a455555_me";
conn_string.Database = "xxxxxxxx";

using (MySqlConnection conn = new MySqlConnection(conn_string.ToString()))
using (MySqlCommand cmd = conn.CreateCommand())
{    //watch out for this SQL injection vulnerability below
     cmd.CommandText = string.Format("INSERT Test (lat, long) VALUES ({0},{1})",
                                    OSGconv.deciLat, OSGconv.deciLon);
     conn.Open();
     cmd.ExecuteNonQuery();
}

I use the environment variable CDPATH

Really great answers and examples!

I would just like to add the fundamental difference between the two,

Operators such as == are not polymorphic, while Equals is

With that concept in mind, if you work out any example (by looking at left hand and right hand reference type, and checking/knowing if the type actually has == operator overloaded and Equals being overriden) you are certain to get the right answer.

:first-child selects the first h1 if and only if it is the first child of its parent element. In your example, the ul is the first child of the div.

The name of the pseudo-class is somewhat misleading, but it's explained pretty clearly here in the spec.

jQuery's :first selector gives you what you're looking for. You can do this:

$('.detail_container h1:first').css("color", "blue");

Look up NR and FNR in the awk manual and then ask yourself what is the condition under which NR==FNR in the following example:

$ cat file1
a
b
c

$ cat file2
d
e

$ awk '{print FILENAME, NR, FNR, $0}' file1 file2
file1 1 1 a
file1 2 2 b
file1 3 3 c
file2 4 1 d
file2 5 2 e

I use the _var naming for member variables of my classes. There are 2 main reasons I do:

1) It helps me keep track of class variables and local function variables when I'm reading my code later.

2) It helps in Intellisense (or other code-completion system) when I'm looking for a class variable. Just knowing the first character is helpful in filtering through the list of available variables and methods.

in the GitLab Enterprise Edition 12.2.0-pre you have to use following: Setting ? Repository ? Default Branch ( expand it) and change the default branch Here

Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.

Usage is simple.

string directoryPath = Path.GetDirectoryName(filePath);

My personal preference is using a mixture of whitespace and brackets like this:

if( statement ) {

    // let's do this

} else {

    // well that sucks

}

I think this looks clean and makes my code very easy to read and most importantly - debug.

SOAPMessage soapMsg = messageFactory.createMessage(headers, xmlByteStream);

SoapDataXml

<tem:Add xmlns:tem="http://tempuri.org/">
    <tem:intA>3</tem:intA>
    <tem:intB>4</tem:intB>
</tem:Add>

use below code to get SoapMessage Object.

public static SOAPMessage getSOAPMessagefromDataXML(String saopBodyXML) throws Exception {
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    dbFactory.setNamespaceAware(true);
    dbFactory.setIgnoringComments(true);
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    InputSource ips = new org.xml.sax.InputSource(new StringReader(saopBodyXML));
    Document docBody = dBuilder.parse(ips);
    System.out.println("Data Document: "+docBody.getDocumentElement());
    
    MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
    SOAPMessage soapMsg = messageFactory.createMessage();
    
    SOAPBody soapBody = soapMsg.getSOAPPart().getEnvelope().getBody();
    soapBody.addDocument(docBody);
    
    return soapMsg;
}

By getting the SoapMessage Object. It is clear that the Soap XML is valid. Then prepare to hit the service to get response. It can be done in many ways.

1. Using Client Code Generated form WSDL.

java.net.URL endpointURL = new java.net.URL(endPointUrl);
javax.xml.rpc.Service service = new org.apache.axis.client.Service();
((org.apache.axis.client.Service) service).setTypeMappingVersion("1.2");
CalculatorSoap12Stub obj_axis = new CalculatorSoap12Stub(endpointURL, service);
int add = obj_axis.add(10, 20);
System.out.println("Response: "+ add);

2. Using javax.xml.soap.SOAPConnection.

public static void getSOAPConnection(SOAPMessage soapMsg) throws Exception {
    System.out.println("===== SOAPConnection =====");
    MimeHeaders headers = soapMsg.getMimeHeaders(); // new MimeHeaders();
    headers.addHeader("SoapBinding",   serverDetails.get("SoapBinding") );
    headers.addHeader("MethodName",    serverDetails.get("MethodName") );
    headers.addHeader("SOAPAction",    serverDetails.get("SOAPAction") );
    headers.addHeader("Content-Type",  serverDetails.get("Content-Type"));
    headers.addHeader("Accept-Encoding", serverDetails.get("Accept-Encoding"));
    if (soapMsg.saveRequired()) {
        soapMsg.saveChanges();
    }
    
    SOAPConnectionFactory newInstance = SOAPConnectionFactory.newInstance();
    javax.xml.soap.SOAPConnection connection = newInstance.createConnection();
    SOAPMessage soapMsgResponse = connection.call(soapMsg, getURL( serverDetails.get("SoapServerURI"), 5*1000 ));
    
    getSOAPXMLasString(soapMsgResponse);
}

3. Form HTTP Connection Classes org.apache.commons.httpclient.

public static void getHttpConnection(SOAPMessage soapMsg) throws SOAPException, IOException {
    System.out.println("===== HttpClient =====");
    HttpClient httpClient = new HttpClient();
    HttpConnectionManagerParams params = httpClient.getHttpConnectionManager().getParams();
    params.setConnectionTimeout(3 * 1000); // Connection timed out
    params.setSoTimeout(3 * 1000);         // Request timed out
    params.setParameter("http.useragent", "Web Service Test Client");

    PostMethod methodPost = new PostMethod( serverDetails.get("SoapServerURI") );
    methodPost.setRequestBody( getSOAPXMLasString(soapMsg) );
    methodPost.setRequestHeader("Content-Type", serverDetails.get("Content-Type") );
    methodPost.setRequestHeader("SoapBinding",  serverDetails.get("SoapBinding") );
    methodPost.setRequestHeader("MethodName",   serverDetails.get("MethodName") );
    methodPost.setRequestHeader("SOAPAction",   serverDetails.get("SOAPAction") );

    methodPost.setRequestHeader("Accept-Encoding", serverDetails.get("Accept-Encoding"));

    try {
        int returnCode = httpClient.executeMethod(methodPost);
        if (returnCode == HttpStatus.SC_NOT_IMPLEMENTED) {
            System.out.println("The Post method is not implemented by this URI");
            methodPost.getResponseBodyAsString();
        } else {
            BufferedReader br = new BufferedReader(new InputStreamReader(methodPost.getResponseBodyAsStream()));
            String readLine;
            while (((readLine = br.readLine()) != null)) {
                System.out.println(readLine);
            }
            br.close();
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        methodPost.releaseConnection();
    }
}

public static void accessResource_AppachePOST(SOAPMessage soapMsg) throws Exception {
    System.out.println("===== HttpClientBuilder =====");
    CloseableHttpClient httpClient = HttpClientBuilder.create().build();
    URIBuilder builder = new URIBuilder( serverDetails.get("SoapServerURI") );
    HttpPost methodPost = new HttpPost(builder.build());
    RequestConfig config = RequestConfig.custom()
            .setConnectTimeout(5 * 1000)
            .setConnectionRequestTimeout(5 * 1000)
            .setSocketTimeout(5 * 1000)
            .build();
    methodPost.setConfig(config);
        HttpEntity xmlEntity = new StringEntity(getSOAPXMLasString(soapMsg), "utf-8");
    methodPost.setEntity(xmlEntity);
        
    methodPost.setHeader("Content-Type", serverDetails.get("Content-Type"));
    methodPost.setHeader("SoapBinding", serverDetails.get("SoapBinding") );
    methodPost.setHeader("MethodName", serverDetails.get("MethodName") );
    methodPost.setHeader("SOAPAction", serverDetails.get("SOAPAction") );
    methodPost.setHeader("Accept-Encoding", serverDetails.get("Accept-Encoding"));
    
    // Create a custom response handler
    ResponseHandler<String> responseHandler = new ResponseHandler<String>() {
        @Override
        public String handleResponse( final HttpResponse response) throws ClientProtocolException, IOException {
            int status = response.getStatusLine().getStatusCode();
            if (status >= 200 && status <= 500) {
                HttpEntity entity = response.getEntity();
                return entity != null ? EntityUtils.toString(entity) : null;
            }
            return "";
        }
    };
    String execute = httpClient.execute( methodPost, responseHandler );
    System.out.println("AppachePOST : "+execute);
}

Full Example:

public class SOAP_Calculator {
    static HashMap<String, String> serverDetails = new HashMap<>();
    static {
        // Calculator
        serverDetails.put("SoapServerURI", "http://www.dneonline.com/calculator.asmx");

        serverDetails.put("Accept-Encoding", "gzip,deflate");

printf("%d", addNumber(a,b))

Here's the documentation for printf.

For a while, I used Nautilus (on Gnome desktop on RHEL 6.0) to delete files on my home folder instead of using the rm command in bash. As a result, the total size shown by

du -sh

did not match the sum of disk usage of each sub-directory, when I used

du -sh *

It took me a while to realise Nautilus sends the deleted files to its Trash folder, and that folder is not listed in du -sh * command. So, just wanted to share this, in case somebody faced the same problem.

Dim path As String = GetFolderPath(SpecialFolder.ApplicationData)
 Dim filepath As String = path + "\" + "your.bat"
    ' Create the file if it does not exist. 
    If File.Exists(filepath) = False Then
        File.Create(filepath)
    Else
    End If
    Dim attributes As FileAttributes
    attributes = File.GetAttributes(filepath)
    If (attributes And FileAttributes.ReadOnly) = FileAttributes.ReadOnly Then
        ' Remove from Readonly the file.
        attributes = RemoveAttribute(attributes, FileAttributes.ReadOnly)
        File.SetAttributes(filepath, attributes)
        Console.WriteLine("The {0} file is no longer RO.", filepath)
    Else
    End If
    If (attributes And FileAttributes.Hidden) = FileAttributes.Hidden Then
        ' Show the file.
        attributes = RemoveAttribute(attributes, FileAttributes.Hidden)
        File.SetAttributes(filepath, attributes)

it saves your .bat file to "Appdata of current user" ,if it does not exist and remove the attributes and after that set the "hidden" attributes to file after writing your cmd code and run it silently and capture all output saves it to file so if u wanna save all output of cmd to file just add your like this

code > C:\Users\Lenovo\Desktop\output.txt

just replace word "code" with your .bat file code or command and after that the directory of output file I found one code recently after searching alot if u wanna run .bat file in vb or c# or simply just add this in the same manner in which i have written

Check out the connection strings web site which has tons of example for your connection strings.

Basically, you need three things:

• name of the server you want to connect to (use "." or (local) or localhost for the local machine)
• name of the database you want to connect to
• some way of defining the security - either integrated Windows security, or define a user name / password combo

For example, if you want to connect to your local machine and the AdventureWorks database using integrated security, use:

server=(local);database=AdventureWorks;integrated security=SSPI;

Or if you have SQL Server Express on your machine in the default installation, and you want to connect to the AdventureWorksLT2008 database, use this:

server=.\SQLExpress;database=AdventureWorksLT2008;integrated Security=SSPI;

$("#ValuationName").bind("keypress", function (event) {
    if (event.charCode!=0) {
        var regex = new RegExp("^[a-zA-Z ]+$");
        var key = String.fromCharCode(!event.charCode ? event.which : event.charCode);
        if (!regex.test(key)) {
            event.preventDefault();
            return false;
        }
    }
});

Use random.choice()

import random

foo = ['a', 'b', 'c', 'd', 'e']
print(random.choice(foo))

For cryptographically secure random choices (e.g. for generating a passphrase from a wordlist) use secrets.choice()

import secrets

foo = ['battery', 'correct', 'horse', 'staple']
print(secrets.choice(foo))

secrets is new in Python 3.6, on older versions of Python you can use the random.SystemRandom class:

import random

secure_random = random.SystemRandom()
print(secure_random.choice(foo))

The correct answer is, that, because the '%'-sign is part of your search expression, it should be part of your VALUE, so whereever you SET @LastName (be it from a programming language or from TSQL) you should set it to '%' + [userinput] + '%'

or, in your example:

DECLARE @LastName varchar(max)
SET @LastName = 'ning'
SELECT Employee WHERE LastName LIKE '%' + @LastName + '%'

Agree with Markus' suggestion to roll your own exception, but the text of the exception should clarify that the problem is in the argument list, not the individual argument values. I'd propose:

class BadCallError(ValueError):
    pass

Used when keyword arguments are missing that were required for the specific call, or argument values are individually valid but inconsistent with each other. ValueError would still be right when a specific argument is right type but out of range.

Shouldn't this be a standard exception in Python?

In general, I'd like Python style to be a bit sharper in distinguishing bad inputs to a function (caller's fault) from bad results within the function (my fault). So there might also be a BadArgumentError to distinguish value errors in arguments from value errors in locals.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

use plt.figure(dpi=1200) before all your plt.plot... and at the end use plt.savefig(... see: http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.figure and http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.savefig

I just found a solution for this.

Just select tableview and clic Editor -> Arrange -> Send to Front

It worked for me and hope it helps you all.

you can use,

 std::sort(v.begin(),v.end());

You can replace those in your Manifest application tag:

<application
    ...
    tools:replace="android:label, android:icon, android:theme"/>

and will work for you.

Explanation

Using such a dependency/library in your gradle file which has those labels in its Manifest's application tag may produce this problem and replacing them in your Manifest is the solution.

>>> lst =  ['abcd', 'e', 'fg', 'hijklmn', 'opq', 'r'] 
>>> print [lst[2*i]+lst[2*i+1] for i in range(len(lst)/2)]
['abcde', 'fghijklmn', 'opqr']

<pre><form name="myform"  method="post" enctype="multipart/form-data">
    <input type="text"   id="name"   name="name" /> 
<input type="submit"/>
</form></pre>

<script language="JavaScript" type="text/javascript">
 var frmvalidator  = new Validator("myform");
    frmvalidator.EnableFocusOnError(false); 
    frmvalidator.EnableMsgsTogether(); 
    frmvalidator.addValidation("name","req","Plese Enter Name"); 

</script>

Note: before using the code above you have to add the gen_validatorv31.js file.

If you're using an implementation of System.Collections.IEnumerable you can do like following to convert it to a List. The following uses Enumerable.Cast method to convert IEnumberable to a Generic List.

//ArrayList Implements IEnumerable interface
ArrayList _provinces = new System.Collections.ArrayList();
_provinces.Add("Western");
_provinces.Add("Eastern");

List<string> provinces = _provinces.Cast<string>().ToList();

If you're using Generic version IEnumerable<T>, The conversion is straight forward. Since both are generics, you can do like below,

IEnumerable<int> values = Enumerable.Range(1, 10);
List<int> valueList = values.ToList();

But if the IEnumerable is null, when you try to convert it to a List, you'll get ArgumentNullException saying Value cannot be null.

IEnumerable<int> values2 = null;
List<int> valueList2 = values2.ToList();

Therefore as mentioned in the other answer, remember to do a null check before converting it to a List.

If you are looking for a simple way, here it is.

Create a utility class like this,

public class ApplicationUtils {

  /**
  * Sets the boolean preference value
  *
  * @param context the current context
  * @param key     the preference key
  * @param value   the value to be set
  */
 public static void setBooleanPreferenceValue(Context context, String key, boolean value) {
     SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
     sp.edit().putBoolean(key, value).apply();
 }

 /**
  * Get the boolean preference value from the SharedPreference
  *
  * @param context the current context
  * @param key     the preference key
  * @return the the preference value
  */
 public static boolean getBooleanPreferenceValue(Context context, String key) {
     SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
     return sp.getBoolean(key, false);
 }

}

At your Main Activity, onCreate()

if(!ApplicationUtils.getBooleanPreferenceValue(this,"isFirstTimeExecution")){
Log.d(TAG, "First time Execution");
ApplicationUtils.setBooleanPreferenceValue(this,"isFirstTimeExecution",true);
// do your first time execution stuff here,
}

You can simple put the default value using default(). See the example

 $table->enum('is_approved', array('0','1'))->default('0');

I have used enum here and the default value is 0.

select * into new_items from productDB.dbo.items

That pretty much is it. THis is the most efficient way to do it.

Either use one of the standard date and time format strings which only specifies the date (e.g. "D" or "d"), or a custom date and time format string which only uses the date parts (e.g. "yyyy/MM/dd").

I've gone through these posts and somehow ended up finding a simple answer, which I'm posting here for those how want short and sweet solutions:

1. Use console.log("Hello World") in your script.
2. Go to https://script.google.com/home/my and select your add-on.
3. Click on the ellipsis menu on Project Details, select Executions.

4. Click on the header of the latest execution and read the log.

There's no built-in functionality to remove duplicates from arrays. Raj's answer seems elegant, but I prefer to use dictionaries.

Dim d As Object
Set d = CreateObject("Scripting.Dictionary")
'Set d = New Scripting.Dictionary

Dim i As Long
For i = LBound(myArray) To UBound(myArray)
    d(myArray(i)) = 1
Next i

Dim v As Variant
For Each v In d.Keys()
    'd.Keys() is a Variant array of the unique values in myArray.
    'v will iterate through each of them.
Next v

EDIT: I changed the loop to use LBound and UBound as per Tomalak's suggested answer. EDIT: d.Keys() is a Variant array, not a Collection.

You could use an image submit button:

<input type="image" src="images/login.jpg" alt="Submit Form" />

Mine is:

border-spacing: 10px;
border-collapse: separate;

For example:

import subprocess

subprocess.call("C:\helloworld.py")

subprocess.call(["python", "-h"])

Daniel A. White Solution works great for classes.

I've got a situation where I had to find input fields like donee_1_card where 1 is an index.

My solution has been

$("input[name^='donee']" && "input[name*='card']")

Though I am not sure how optimal it is.

             </script>
        </div>
    </div>
</div>

var player = null;
$( document ).ready(function() {
    resizeHeroVideo();
} );

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

function resizeHeroVideo() {
    var content = $('#hero');
    var contentH = viewportSize.getHeight();
    contentH -= 158;
    content.css('height',contentH);

    if(player != null) {
        var iframe = $('.videoWrapper iframe');
        var iframeH = contentH - 150;
        if (isMobile) {
            iframeH = 163; 
        }
        iframe.css('height',iframeH);
        var iframeW = iframeH/9 * 16;
        iframe.css('width',iframeW);
    }
}

resizeHeroVideo is called only after the Youtube player has fully loaded (on page load does not work), and whenever the browser window is resized. When it runs, it calculates the height and width of the iframe and assigns the appropriate values maintaining the correct aspect ratio. This works whether the window is resized horizontally or vertically.

For my Raspberry Pi 3B model it was

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

To output obj:

console.log(obj, null, 4)

Just leaving this here for future visitors:

In my case the /WEB-INF/classes directory was missing. If you are using Eclipse, make sure the .settings/org.eclipse.wst.common.component is correct (Deployment Assembly in the project settings).

In my case it was missing

    <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>
    <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/test/resources"/>

This file is also a common source of errors as mentioned by Anuj (missing dependencies of other projects).

Otherwise, hopefully the other answers (or the "Problems" tab) will help you.

In my case, the problem is caused by adb connected with another device.

If several devices are connected in PC, remove other devices except required one.

I'm trying to close users connection in version 1.0 and found this method:

socket.conn.close()

The difference between this method and disconnect() is that the client will keep trying to reconnect to the server.

By default, inheritance is private. You have to explicitly use public:

class Bar : public Foo

here is another solution...

System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];

System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
    m.Write (buffer, 0, buffer.Length);
}  
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();

hope it helps!

you have to assign connection to your command object, like..

SqlCommand cmd=new SqlCommand ("insert into time(project,iteration)values('"+this .name1 .SelectedValue +"','"+this .iteration .SelectedValue +"')");
cmd.Connection = conn; 

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>

This solution works for me (I was using 2.2 before). Also, I am using Java Based Configuration for Servlet 3.0 and no need to have web.xml file.

The variable to use would be process.platform

On Mac the variable returns darwin. On Windows, it returns win32 (even on 64 bit).

Current possible values are:

• aix
• darwin
• freebsd
• linux
• openbsd
• sunos
• win32

I just set this at the top of my jakeFile:

var isWin = process.platform === "win32";

It works in samsung touchwiz launcher

public static void setBadge(Context context, int count) {
    String launcherClassName = getLauncherClassName(context);
    if (launcherClassName == null) {
        return;
    }
    Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE");
    intent.putExtra("badge_count", count);
    intent.putExtra("badge_count_package_name", context.getPackageName());
    intent.putExtra("badge_count_class_name", launcherClassName);
    context.sendBroadcast(intent);
}

public static String getLauncherClassName(Context context) {

    PackageManager pm = context.getPackageManager();

    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);

    List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0);
    for (ResolveInfo resolveInfo : resolveInfos) {
        String pkgName = resolveInfo.activityInfo.applicationInfo.packageName;
        if (pkgName.equalsIgnoreCase(context.getPackageName())) {
            String className = resolveInfo.activityInfo.name;
            return className;
        }
    }
    return null;
}

I had a similar issue - very slow xml downloads followed by an empty package list. The SDK, it seems, was trying to use legacy Java installation. Setting the JAVA_HOME to the 1.6 jdk did the trick.

Dim userReply As String
userReply = Microsoft.VisualBasic.InputBox("Message")
If userReply = "" Then 
  MsgBox("You did not enter anything. Try again")
ElseIf userReply.Length = 0 Then 
  MsgBox("You did not enter anything")
End If

As alluded to by Eric, you can use environ with ComputerName argument like so:

MsgBox Environ("USERNAME")

Some additional information that might be helpful for you to know:

1. The arguments are not case sensitive.
2. There is a slightly faster performing string version of the Environ function. To invoke it, use a dollar sign. (Ex: Environ$("username")) This will net you a small performance gain.
3. You can retrieve all System Environment Variables using this function. (Not just username.) A common use is to get the "ComputerName" value to see which computer the user is logging onto from.
4. I don't recommend it for most situations, but it can be occasionally useful to know that you can also access the variables with an index. If you use this syntax the the name of argument and the value are returned. In this way you can enumerate all available variables. Valid values are 1 - 255.

    Sub EnumSEVars()
        Dim strVar As String
        Dim i As Long
        For i = 1 To 255
            strVar = Environ$(i)
            If LenB(strVar) = 0& Then Exit For
            Debug.Print strVar
        Next
    End Sub

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

Try redirecting the output to Out-Null. Like so,

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

You can see the results in MB format, with the division of 1024 x 1024 which is equal to 1 MB.

int dataSize = 1024 * 1024;

System.out.println("Used Memory   : " + (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory())/dataSize + " MB");
System.out.println("Free Memory   : " + Runtime.getRuntime().freeMemory()/dataSize + " MB");
System.out.println("Total Memory  : " + Runtime.getRuntime().totalMemory()/dataSize + " MB");
System.out.println("Max Memory    : " + Runtime.getRuntime().maxMemory()/dataSize + " MB");  

I had this problem in a list of post in a blog, the post are in a view inside a foreach, then is difficult select it in javascript, and the problem of post method and token also exists.

This the code for javascript at the end of the view, I generate the token in javascript functión inside the view and not in a external js file, then is easy use php lavarel to generate it with csrf_token() function, and send the "delete" method directly in params. You can see that I don´t use in var route: {{ route('post.destroy', $post->id}} because I don´t know the id I want delete until someone click in destroy button, if you don´t have this problem you can use {{ route('post.destroy', $post->id}} or other like this.

  $(function(){
    $(".destroy").on("click", function(){
         var vid = $(this).attr("id");
         var v_token = "{{csrf_token()}}";
         var params = {_method: 'DELETE', _token: v_token};
         var route = "http://imagica.app/posts/" + vid + "";
    $.ajax({
         type: "POST",
         url: route,
         data: params
    });
   });
  });

and this the code of content in view (inside foreach there are more forms and the data of each post but is not inportant by this example), you can see I add a class "delete" to button and I call class in javascript.

      @foreach($posts as $post)
          <form method="POST">
            <button id="{{$post->id}}" class="btn btn-danger btn-sm pull-right destroy" type="button" >eliminar</button>
          </form>
      @endforeach

FILE_NAME = 'file.txt'

wordCounter = {}

with open(FILE_NAME,'r') as fh:
  for line in fh:

    word_list = line.replace(',','').replace('\'','').replace('.','').lower().split()
    for word in word_list:
      # Adding  the word into the wordCounter dictionary.
      if word not in wordCounter:
        wordCounter[word] = 1
      else:
        # if the word is already in the dictionary update its count.
        wordCounter[word] = wordCounter[word] + 1

print('{:15}{:3}'.format('Word','Count'))
print('-' * 18)

# printing the words and its occurrence.
for  (word,occurance)  in wordCounter.items(): 
  print('{:15}{:3}'.format(word,occurance))

I had this issue as well and jaywhy13 answer was good but not enough.

I had to change a setting: Settings -> Gradle -> MyProject

There you need to check the "auto import" and select "use customizable gradle wrapper". After that it should refresh gradle and you can build again. If not try a reboot of Android Studio.

The sum function will add all numbers together to produce a single number, not a vector (well, at least not a vector of length greater than 1).

It looks as though at least one of your columns is a factor. You could convert them into numeric vectors by checking this

head(as.numeric(data$col1))  # make sure this gives you the right output

And if that looks right, do

data$col1 <- as.numeric(data$col1)
data$col2 <- as.numeric(data$col2)

You might have to convert them into characters first. In which case do

data$col1 <- as.numeric(as.character(data$col1))
data$col2 <- as.numeric(as.character(data$col2))

It's hard to tell which you should do without being able to see your data.

Once the columns are numeric, you just have to do

data$col3 <- data$col1 + data$col2

It is a 32bit declaration. If you type at the top of an assembly file the statement [bits 32], then you don't need to type DWORD PTR. So for example:

[bits 32]
.
.
and  [ebp-4], 0

I spent a lot of time trying different answers all around the internet, and I suspect the reasons why one thing works for some people and not for others is due to very small weird differences in application. For context, I needed to read in file names from a csv file that had strange and/or unmappable unicode characters and write them to a new csv file. For what it's worth, here's what worked for me:

s = '\u00e7\u00a3\u0085\u00e5\u008d\u0095' # csv freaks if you try to write this
s = repr(s.encode('utf-8', 'ignore'))[2:-1]

You can create a custom serializer inline in the mixin. Then annotate a field with it. See example below that appends " - something else " to lang field. This is kind of hackish - if your serializer requires something like a repository or anything injected by spring, this is going to be a problem. Probably best to use a custom deserializer/serializer instead of a mixin.

package com.test;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.JsonAutoDetect.Visibility;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;
import com.fasterxml.jackson.core.JsonGenerator;

import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import com.test.Argument;
import java.io.IOException;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
//Serialize only fields explicitly mentioned by this mixin.
@JsonAutoDetect(
    fieldVisibility = Visibility.NONE,
    setterVisibility = Visibility.NONE,
    getterVisibility = Visibility.NONE,
    isGetterVisibility = Visibility.NONE,
    creatorVisibility = Visibility.NONE
)
@JsonPropertyOrder({"lang", "name", "value"})
public abstract class V2ArgumentMixin {

  @JsonProperty("name")
  private String name;

  @JsonSerialize(using = LangCustomSerializer.class, as=String.class)
  @JsonProperty("lang")
  private String lang;

  @JsonProperty("value")
  private Object value;


  
  public static class LangCustomSerializer extends JsonSerializer<String> {

    @Override
    public void serialize(String value,
                          JsonGenerator jsonGenerator,
                          SerializerProvider serializerProvider)
        throws IOException, JsonProcessingException {
      jsonGenerator.writeObject(value.toString() + "  - something else");
    }
  }
}

You can do this...

var string = 'This is\n' +
'a multiline\n' + 
'string';

You can do it on one line of code (without array declaration):

object[] someArray = new object[] 
{
    "aaaa",
    3,
    null
};
bool containsSomeNull = someArray.Any(x => x == null);

WHILE is more flexible. FOR is more concise in those instances in which it applies.

FOR is great for loops which have a counter of some kind, like

for (int n=0; n<max; ++n)

You can accomplish the same thing with a WHILE, of course, as others have pointed out, but now the initialization, test, and increment are broken across three lines. Possibly three widely-separated lines if the body of the loop is large. This makes it harder for the reader to see what you're doing. After all, while "++n" is a very common third piece of the FOR, it's certainly not the only possibility. I've written many loops where I write "n+=increment" or some more complex expression.

FOR can also work nicely with things other than a counter, of course. Like

for (int n=getFirstElementFromList(); listHasMoreElements(); n=getNextElementFromList())

Etc.

But FOR breaks down when the "next time through the loop" logic gets more complicated. Consider:

initializeList();
while (listHasMoreElements())
{
  n=getCurrentElement();
  int status=processElement(n);
  if (status>0)
  {
    skipElements(status);
    advanceElementPointer();
  }
  else
  {
    n=-status;
    findElement(n);
  }
}

That is, if the process of advancing may be different depending on conditions encountered while processing, a FOR statement is impractical. Yes, sometimes you could make it work with a complicated enough expressions, use of the ternary ?: operator, etc, but that usually makes the code less readable rather than more readable.

In practice, most of my loops are either stepping through an array or structure of some kind, in which case I use a FOR loop; or are reading a file or a result set from a database, in which case I use a WHILE loop ("while (!eof())" or something of that sort).

It is because you forgot to pass in event into the click function:

$('.menuOption').on('click', function (e) { // <-- the "e" for event

    e.preventDefault(); // now it'll work

    var categories = $(this).attr('rel');
    $('.pages').hide();
    $(categories).fadeIn();
});

On a side note, e is more commonly used as opposed to the word event since Event is a global variable in most browsers.

The best use of tags you should use:

<img src="" alt=""/>

Also you can use in HTML5:

<img src="" alt="">

These two are completely valid in HTML5 Pick one of them and stick with that.

Convert timestamp into Date object.

If timestamp object is invalid then return current date.

class func toDate(_ timestamp: Any?) -> Date? {
    if let any = timestamp {
        if let str = any as? NSString {
            return Date(timeIntervalSince1970: str.doubleValue)
        } else if let str = any as? NSNumber {
            return Date(timeIntervalSince1970: str.doubleValue)
        }
    }
    return nil
}

To see how the repr works within a class, run the following code, first with and then without the repr method.

class Coordinate (object):
    def __init__(self,x,y):
        self.x = x
        self.y = y

    def getX(self):
        # Getter method for a Coordinate object's x coordinate.
        # Getter methods are better practice than just accessing an attribute directly
        return self.x
    def getY(self):

        # Getter method for a Coordinate object's y coordinate
        return self.y

    def __repr__(self):  #remove this and the next line and re-run
        return 'Coordinate(' + str(self.getX()) + ',' + str(self.getY()) + ')' 

>>>c = Coordinate(2,-8)
>>>print(c)

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

Use clean build folder (command + shift + K) and rebuild app can shortly fix this issue. However, the build time will increase since you have cleaned the build folder.

If you can change the order of the elements:

 int[] myArray = new int[]{1, 3, 8, 5, 7, };
 Arrays.sort(myArray);
 int max = myArray[myArray.length - 1];

If you can't change the order of the elements:

int[] myArray = new int[]{1, 3, 8, 5, 7, };
int max = Integer.MIN_VALUE;
for(int i = 0; i < myArray.length; i++) {
      if(myArray[i] > max) {
         max = myArray[i];
      }
}

There are three places where a file, say, can be - the (committed) tree, the index and the working copy. When you just add a file to a folder, you are adding it to the working copy.

When you do something like git add file you add it to the index. And when you commit it, you add it to the tree as well.

It will probably help you to know the three more common flags in git reset:

git reset [--<mode>] [<commit>]

This form resets the current branch head to <commit> and possibly updates the index (resetting it to the tree of <commit>) and the working tree depending on <mode>, which must be one of the following:
--soft

Does not touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

--mixed

Resets the index but not the working tree (i.e., the changed files are preserved but not marked for commit) and reports what has not been updated. This is the default action.

--hard

Resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded.

Now, when you do something like git reset HEAD, what you are actually doing is git reset HEAD --mixed and it will "reset" the index to the state it was before you started adding files / adding modifications to the index (via git add). In this case, no matter what the state of the working copy was, you didn't change it a single bit, but you changed the index in such a way that is now in sync with the HEAD of the tree. Whether git add was used to stage a previously committed but changed file, or to add a new (previously untracked) file, git reset HEAD is the exact opposite of git add.

git rm, on the other hand, removes a file from the working directory and the index, and when you commit, the file is removed from the tree as well. git rm --cached, however, removes the file from the index alone and keeps it in your working copy. In this case, if the file was previously committed, then you made the index to be different from the HEAD of the tree and the working copy, so that the HEAD now has the previously committed version of the file, the index has no file at all, and the working copy has the last modification of it. A commit now will sync the index and the tree, and the file will be removed from the tree (leaving it untracked in the working copy). When git add was used to add a new (previously untracked) file, then git rm --cached is the exact opposite of git add (and is pretty much identical to git reset HEAD).

Git 2.25 introduced a new command for these cases, git restore, but as of Git 2.28 it is described as “experimental” in the man page, in the sense that the behavior may change.

jQuery can handle JSONP, just pass an url formatted with the callback=? parameter to the $.getJSON method, for example:

$.getJSON("https://api.ipify.org/?format=json", function(e) {_x000D_
    console.log(e.ip);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

This example is of a really simple JSONP service implemented on with api.ipify.org.

If you aren't looking for a cross-domain solution the script can be simplified even more, since you don't need the callback parameter, and you return pure JSON.
