First Record should be add

"_id" = 1    in your db

$database = "demo";
$collections ="democollaction";
echo getnextid($database,$collections);

function getnextid($database,$collections){

     $m = new MongoClient();
    $db = $m->selectDB($database);
    $cursor = $collection->find()->sort(array("_id" => -1))->limit(1);
    $array = iterator_to_array($cursor);

    foreach($array as $value){



        return $value["_id"] + 1;

    }
 }

Another method without having to update your Python code at all, would be to redirect via the console.

Basically, have your Python script print() as usual, then call the script from the command line and use command line redirection. Like this:

$ python ./myscript.py > output.txt

Your output.txt file will now contain all output from your Python script.

Edit:
To address the comment; for Windows, change the forward-slash to a backslash.
(i.e. .\myscript.py)

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

to explode with '.' use

explode('\\.','a.b');

Difference Between Static and Volatile :

Static Variable: If two Threads(suppose t1 and t2) are accessing the same object and updating a variable which is declared as static then it means t1 and t2 can make their own local copy of the same object(including static variables) in their respective cache, so update made by t1 to the static variable in its local cache wont reflect in the static variable for t2 cache .

Static variables are used in the context of Object where update made by one object would reflect in all the other objects of the same class but not in the context of Thread where update of one thread to the static variable will reflect the changes immediately to all the threads (in their local cache).

Volatile variable: If two Threads(suppose t1 and t2) are accessing the same object and updating a variable which is declared as volatile then it means t1 and t2 can make their own local cache of the Object except the variable which is declared as a volatile . So the volatile variable will have only one main copy which will be updated by different threads and update made by one thread to the volatile variable will immediately reflect to the other Thread.

Try the :host > /deep/ :

Add the following to the parent.component.less file

:host {
    /deep/ app-child-component {
       //your child style
    }
}

Replace the app-child-component by your child selector

I think the cleanest way is this!

 <?php
  $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
  $supportedLanguages=['en','fr','gr'];
  if(!in_array($lang,$supportedLanguages)){
     $lang='en';
  }
    require("index_".$lang.".php");

The problem I was having is that I was only using https for my GitHub account. I needed to make sure that my GitHub account was setup for ssh access and that GitHub and heroku were both using the same public keys. These are the steps I took:

1. Navigate to the ~/.ssh directory and delete the id_rsa and id_rsa.pub if they are there. I started with new keys, though it might not be necessary.

   $ cd ~/.ssh
   $ rm id_rsa id_rsa.pub
   

2. Follow the steps on gitHub to generate ssh keys

3. Login to heroku, create a new site and add your public keys:

   $ heroku login
   ...
   $ heroku create
   $ heroku keys:add
   $ git push heroku master
   

You need the xml.etree.ElementTree.fromstring(text)

from xml.etree.ElementTree import XML, fromstring
myxml = fromstring(text)

That's the easy answer:

$query="SELECT * FROM CountryInfo WHERE Name = '".$name."'";

and you define $name whatever you want.
And another way, the complex way, is like that:

$query = " SELECT '" . $GLOBALS['Name'] . "' .* " .
         " FROM CountryInfo " .
         " INNER JOIN District " .
         " ON District.CountryInfoId = CountryInfo.CountryInfoId " .
         " INNER JOIN City " .
         " ON City.DistrictId = District.DistrictId " .
         " INNER JOIN '" . $GLOBALS['Name'] . "' " .
         " ON '" . $GLOBALS['Name'] . "'.CityId = City.CityId " .
         " WHERE CountryInfo.Name = '" . $GLOBALS['CountryName'] .
         "'";

A simple ES6 way to get both the first key and remaining parts in a string would be:

 const [key, ...rest] = "good_luck_buddy".split('_')
 const value = rest.join('_')
 console.log(key, value) // good, luck_buddy

Use stored procedures.

And even assuming you would want not to use stored procedures - there is at most 3 commands to be run, not 4. Second getting id is useless, as you can do "INSERT INTO ... RETURNING".

This problem occurred for me when I imported an existing project into eclipse. What happens is it copied all the files not in the package, but outside the package. Hence, when I tried run > run configurations, it couldn't find the main method because it was not in the package. All I did was copy the files into the package and Eclipse was then able to detect the main method. So ultimately make sure that Eclipse can find your main method, by making sure that your java files are in the right package.

I was using old version 1.0.beta.6 of handlebars, i think somewhere during 1.1 - 1.3 this functionality was added, so updating to 1.3.0 solved the issue, here is the usage:

Usage:

Pass the intent with value on First Activity:

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("uid", uid.toString());
intent.putExtra("pwd", pwd.toString());
startActivity(intent);

Receive intent on second Activity;-

Intent intent = getIntent();
String user = intent.getStringExtra("uid");
String pass = intent.getStringExtra("pwd");

We use generally two method in intent to send the value and to get the value. For sending the value we will use intent.putExtra("key", Value); and during receive intent on another activity we will use intent.getStringExtra("key"); to get the intent data as String or use some other available method to get other types of data (Integer, Boolean, etc.). The key may be any keyword to identify the value means that what value you are sharing. Hope it will work for you.

In Sharepoint Server 2010 they are stored here:

You can use jquery for this by utilizing addClass() method

CSS

 .defaultInput
    {
     width: 100px;
     height:25px;
     padding: 5px;
    }

.error
{
 border:1px solid red;
}

<input type="text" class="defaultInput"/>

Jquery Code

$(document).ready({
  $('.defaultInput').focus(function(){
       $(this).addClass('error');
  });
});

Update: You can remove that error class using

$('.defaultInput').removeClass('error');

It won't remove that default style. It will remove .error class only

In this scenario, the outer <div> has a width and height of 90%. The inner div> has a width of 100% of its parent. Both scale when re-sizing the window.

HTML

<div>
    <div>Hello there</div>
</div>

CSS

html, body {
    width: 100%;
    height: 100%;
}

body > div {
    width: 90%;
    height: 100%;
    background: green;
}

body > div > div {
    width: 100%;
    background: red;

Demo

Try before buy

$this->db->where('emailsToCampaigns.campaignId !=' , $campaignId);

This should work (which you have tried)

To debug you might place this code just after you execute your query to see what exact SQL it is producing, this might give you clues, you might add that to the question to allow for further help.

$this->db->get();              // your query executing

echo '<pre>';                  // to preserve formatting
die($this->db->last_query());  // halt execution and print last ran query.

Even better, try an OrderedDict (assuming you want something like a list). Closer to a list than a regular dict since the keys have an order just like list elements have an order. With a regular dict, the keys have an arbitrary order.

Note that this is available in Python 3 and 2.7. If you want to use with an earlier version of Python you can find installable modules to do that.

height: 100% gives the element 100% height of its parent container.

height: auto means the element height will depend upon the height of its children.

Consider these examples:

height: 100%

<div style="height: 50px">
    <div id="innerDiv" style="height: 100%">
    </div>
</div>

#innerDiv is going to have height: 50px

height: auto

<div style="height: 50px">
    <div id="innerDiv" style="height: auto">
          <div id="evenInner" style="height: 10px">
          </div>
    </div>
</div>

#innerDiv is going to have height: 10px

You can use this CSS:

.content {
    height: 100%;
    display: inline-table;
    background-color: blue;
}

Technically YAML is a superset of JSON. This means that, in theory at least, a YAML parser can understand JSON, but not necessarily the other way around.

See the official specs, in the section entitled "YAML: Relation to JSON".

In general, there are certain things I like about YAML that are not available in JSON.

• As @jdupont pointed out, YAML is visually easier to look at. In fact the YAML homepage is itself valid YAML, yet it is easy for a human to read.
• YAML has the ability to reference other items within a YAML file using "anchors." Thus it can handle relational information as one might find in a MySQL database.
• YAML is more robust about embedding other serialization formats such as JSON or XML within a YAML file.

In practice neither of these last two points will likely matter for things that you or I do, but in the long term, I think YAML will be a more robust and viable data serialization format.

Right now, AJAX and other web technologies tend to use JSON. YAML is currently being used more for offline data processes. For example, it is included by default in the C-based OpenCV computer vision package, whereas JSON is not.

You will find C libraries for both JSON and YAML. YAML's libraries tend to be newer, but I have had no trouble with them in the past. See for example Yaml-cpp.

Obtaining UTC date

gmdate("Y-m-d H:i:s");

Obtaining UTC timestamp

time();

The result will not be different even you have date_default_timezone_set on your code.

Lorie's answer is good, but if a user selects a range that contains locked and unlocked cells, the data in the locked/protected cells can be deleted.

Isaac's answer is great, but doesn't work if the user highlights a range that has both locked and unlocked cells.

I modified Isaac's code a bit to undo changes if ANY of the cells in the target range are locked. It also displays a message explaining why the action was undone. Combined with Lorie's answer, I was able to achieve the desired result of being able to sort/filter a protected sheet, while still allowing a user to make changes to an unprotected cell.

Follow the instructions in Lorie's answer, then put the following code in the worksheet module:

Private Sub Worksheet_Change(ByVal Target As Range)
    For Each i In Target
       If i.Locked = True Then
            Application.EnableEvents = False
            Application.Undo
            Application.EnableEvents = True
            MsgBox "Your action was undone because it made changes to a locked cell.", , "Action Undone"
        Exit For
        End If
    Next i
End Sub

Plunker

$scope.remove = function(item) { 
    $scope.cards.splice(0, 1);     
  }

Using Visual Studio

1. Attach a debugger to the process (e.g. start with debugging or Debug > Attach to process)
2. While debugging, show the Modules window (Debug > Windows > Modules)

This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).

Using Process Explorer

If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)

Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.

Programmatically

Check this SO question that explains how to do it.

I know the question is already answered, but I find that the existing answers are not valid:
they will return True for linked tables with a non working back-end.
Using DCount can be much slower, but is more reliable.

Function IsTable(sTblName As String) As Boolean
    'does table exists and work ?
    'note: finding the name in the TableDefs collection is not enough,
    '      since the backend might be invalid or missing

    On Error GoTo hell
    Dim x
    x = DCount("*", sTblName)
    IsTable = True
    Exit Function
hell:
    Debug.Print Now, sTblName, Err.Number, Err.Description
    IsTable = False

End Function

In Oracle 11g and later, you can use a recursive sub-query and simple string functions (which may be faster than regular expressions and correlated hierarchical sub-queries):

Oracle Setup:

CREATE TABLE table_name ( name, project, error ) as
 select 108, 'test',  'Err1, Err2, Err3' from dual union all
 select 109, 'test2', 'Err1'             from dual;

Query:

WITH table_name_error_bounds ( name, project, error, start_pos, end_pos ) AS (
  SELECT name,
         project,
         error,
         1,
         INSTR( error, ', ', 1 )
  FROM   table_name
UNION ALL
  SELECT name,
         project,
         error,
         end_pos + 2,
         INSTR( error, ', ', end_pos + 2 )
  FROM   table_name_error_bounds
  WHERE  end_pos > 0
)
SELECT name,
       project,
       CASE end_pos
       WHEN 0
       THEN SUBSTR( error, start_pos )
       ELSE SUBSTR( error, start_pos, end_pos - start_pos )
       END AS error
FROM   table_name_error_bounds

Output:

NAME | PROJECT | ERROR
---: | :------ | :----
 108 | test    | Err1 
 109 | test2   | Err1 
 108 | test    | Err2 
 108 | test    | Err3

Not with CSS, no.

You have the wrong table set on the command. You should use the following on your setup:

ALTER TABLE scode_tracker.ap_visits ENGINE=MyISAM;

This is a place in which C++ has a strange rule. Before being able to compile a call to a function the compiler must know the function name, return value and all parameters. This can be done by adding a "prototype". In your case this simply means adding before main the following line:

int writeFile();

this tells the compiler that there exist a function named writeFile that will be defined somewhere, that returns an int and that accepts no parameters.

Alternatively you can define first the function writeFile and then main because in this case when the compiler gets to main already knows your function.

Note that this requirement of knowing in advance the functions being called is not always applied. For example for class members defined inline it's not required...

struct Foo {
    void bar() {
        if (baz() != 99) {
            std::cout << "Hey!";
        }
    }

    int baz() {
        return 42;
    }
};

In this case the compiler has no problem analyzing the definition of bar even if it depends on a function baz that is declared later in the source code.

    fig = plt.figure()
    plt.errorbar(tuple(indices), tuple(values), tuple(errors), marker='.')

    plt.ylim([-0.5, len(values) - 0.5])
    plt.xlabel('My x-axis title')
    plt.ylabel('My y-axis title')

    # title
    plt.title(title)

    # save as file
    plt.savefig(plot_file_name)

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

Cake supports AssemblyInfo files patching. With cake in hands you have infinite ways to implement automatic version incrementing.

Simple example of incrementing version like C# compiler does:

Setup(() =>
{
    // Executed BEFORE the first task.
    var datetimeNow = DateTime.Now;
    var daysPart = (datetimeNow - new DateTime(2000, 1, 1)).Days;
    var secondsPart = (long)datetimeNow.TimeOfDay.TotalSeconds/2;
    var assemblyInfo = new AssemblyInfoSettings
    {
        Version = "3.0.0.0",
        FileVersion = string.Format("3.0.{0}.{1}", daysPart, secondsPart)
    };
    CreateAssemblyInfo("MyProject/Properties/AssemblyInfo.cs", assemblyInfo);
});

Here:

• Version - is assembly version. Best practice is to lock major version number and leave remaining with zeroes (like "1.0.0.0").
• FileVersion - is assembly file version.

Note that you can patch not only versions but also all other necessary information.

It's still valid to use IE=edge,chrome=1.

But, since the chrome frame project has been wound down the chrome=1 part is redundant for browsers that don't already have the chrome frame plug in installed.

I use the following for correctness nowadays

Atom is still in beta (v0.123 as I'm writing this) but it's moving fast. Way faster than Sublime. New builds are released on a weekly basis, sometimes even few of them in the same week. In its short life span, it had more releases than Sublime which takes months to release a new feature or a bug fix. Here's an updated take on things looking back on the path Atom has taken since the launch of the beta:

1. Sublime has better performance than Atom. Simply because it's written in C++. Atom on the other hand is a web based desktop app built on top of Chromium, and while they take performance close to heart, it will be really hard or even impossible to reach the same speed and responsiveness. Last July Atom began using React and it gave it a nice performance boost but you can still feel the difference. Apart from that, if Atom’s performance issues will not push users away - Sublime better speed up the release cycle, brush up its small UX tweaks, and consider letting in more contributors because this is where Atom is winning.

2. Atom's package ecosystem is also growing really fast, it might not be as big as Sublime's at the moment but I have a feeling that with GitHub at it's back it will keep growing even faster. It probably has the majority of IDE like plug-ins you can think of. A major difference right now is that it can't handle files bigger than 2MB so it's something to keep in mind.

3. The one thing you'll notice first is that the Sublime minimap is gone! Other than that, the first impression is that Atom looks almost the same as Sublime. I wrote a more in depth comparison about it in this blog post.

4. No easy straightforward way to port your Sublime configurations, packages and such as far as I know.

You forgot the () at the end. It is not a variable, but a function and when there are not parameters, you still need the () at the end.

For future coding practices, I would highly recommend reforming the code a little bit as this can become frustrating to read:

 public string LastName
 { get { return lastName; } set { lastName = value; } }

If there is any kind of processing which happens in here (thankfully doesn't happen here), it will become very confusing. If you're going to pass your code onto someone else, I would recommend:

public string LastName
{
  get
  {
     return lastName;
  }
  set
  {
     lastName = value;
  }
}

It's a lot longer, but it's much easier to read when glancing at a huge section of code.

@Mock is used to declare/mock the references of the dependent beans, while @InjectMocks is used to mock the bean for which test is being created.

For example:

public class A{

   public class B b;

   public void doSomething(){

   }

}

test for class A:

public class TestClassA{

   @Mocks
   public class B b;

   @InjectMocks
   public class A a;

   @Test
   public testDoSomething(){

   }

}

You can make the border transparent. In this way it exists, but is invisible, so it doesn't push anything around:

.jobs .item {
   background: #eee;
   border: 1px solid transparent;
}

.jobs .item:hover {
   background: #e1e1e1;
   border: 1px solid #d0d0d0;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

For elements that already have a border, and you don't want them to move, you can use negative margins:

.jobs .item {
    background: #eee;
    border: 1px solid #d0d0d0;
}

.jobs .item:hover {
   background: #e1e1e1;
    border: 3px solid #d0d0d0;
    margin: -2px;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

Another possible trick for adding width to an existing border is to add a box-shadow with the spread attribute of the desired pixel width.

.jobs .item {
    background: #eee;
    border: 1px solid #d0d0d0;
}

.jobs .item:hover {
    background: #e1e1e1;
    box-shadow: 0 0 0 2px #d0d0d0;
}

I think you are using 'global' incorrectly. See Python reference. You should declare variable without global and then inside the function when you want to access global variable you declare it global yourvar.

#!/usr/bin/python

total

def checkTotal():
    global total
    total = 0

See this example:

#!/usr/bin/env python

total = 0

def doA():
    # not accessing global total
    total = 10

def doB():
    global total
    total = total + 1

def checkTotal():
    # global total - not required as global is required
    # only for assignment - thanks for comment Greg
    print total

def main():
    doA()
    doB()
    checkTotal()

if __name__ == '__main__':
    main()

Because doA() does not modify the global total the output is 1 not 11.

You can use componentWillReceiveProps.

constructor(props) {
    super(props);
    this.state = {
      productdatail: ''
    };
}

componentWillReceiveProps(nextProps){
    this.setState({ productdatail: nextProps.productdetailProps })
}

Set setHasMenuOptions(true) works if application has a theme with Actionbar such as Theme.MaterialComponents.DayNight.DarkActionBar or Activity has it's own Toolbar, otherwise onCreateOptionsMenu in fragment does not get called.

If you want to use standalone Toolbar you either need to get activity and set your Toolbar as support action bar with

(requireActivity() as? MainActivity)?.setSupportActionBar(toolbar)

which lets your fragment onCreateOptionsMenu to be called.

Other alternative is, you can inflate your Toolbar's own menu with toolbar.inflateMenu(R.menu.YOUR_MENU) and item listener with

toolbar.setOnMenuItemClickListener {
   // do something
   true
}

I have a Windows service, and I added the following line to the constructor for my service:

using System.Diagnostics;
try {
    Process p = Process.Start(@"C:\Windows\system32\calc.exe");
} catch {
    Debugger.Break();
}

When I tried to run this, the Process.Start() call was made, and no exception occurred. However, the calc.exe application did not show up. In order to make it work, I had edit the properties for my service in the Service Control Manager to enable interaction with the desktop. After doing that, the Process.Start() opened calc.exe as expected.

But as others have said, interaction with the desktop is frowned upon by Microsoft and has essentially been disabled in Vista. So even if you can get it to work in XP, I don't know that you'll be able to make it work in Vista.

If, like me, you were expecting a list of usage differences between Underscore.js and Lodash, there's a guide for migrating from Underscore.js to Lodash.

Here's the current state of it for posterity:

• Underscore _.any is Lodash _.some
• Underscore _.all is Lodash _.every
• Underscore _.compose is Lodash _.flowRight
• Underscore _.contains is Lodash _.includes
• Underscore _.each doesn’t allow exiting by returning false
• Underscore _.findWhere is Lodash _.find
• Underscore _.flatten is deep by default while Lodash is shallow
• Underscore _.groupBy supports an iteratee that is passed the parameters (value, index, originalArray), while in Lodash, the iteratee for _.groupBy is only passed a single parameter: (value).
• Underscore.js _.indexOf with third parameter undefined is Lodash _.indexOf
• Underscore.js _.indexOf with third parameter true is Lodash _.sortedIndexOf
• Underscore _.indexBy is Lodash _.keyBy
• Underscore _.invoke is Lodash _.invokeMap
• Underscore _.mapObject is Lodash _.mapValues
• Underscore _.max combines Lodash _.max & _.maxBy
• Underscore _.min combines Lodash _.min & _.minBy
• Underscore _.sample combines Lodash _.sample & _.sampleSize
• Underscore _.object combines Lodash _.fromPairs and _.zipObject
• Underscore _.omit by a predicate is Lodash _.omitBy
• Underscore _.pairs is Lodash _.toPairs
• Underscore _.pick by a predicate is Lodash _.pickBy
• Underscore _.pluck is Lodash _.map
• Underscore _.sortedIndex combines Lodash _.sortedIndex & _.sortedIndexOf
• Underscore _.uniq by an iteratee is Lodash _.uniqBy
• Underscore _.where is Lodash _.filter
• Underscore _.isFinite doesn’t align with Number.isFinite
  (e.g. _.isFinite('1') returns true in Underscore.js, but false in Lodash)
• Underscore _.matches shorthand doesn’t support deep comparisons
  (e.g., _.filter(objects, { 'a': { 'b': 'c' } }))
• Underscore = 1.7 & Lodash _.template syntax is
  _.template(string, option)(data)
• Lodash _.memoize caches are Map like objects
• Lodash doesn’t support a context argument for many methods in favor of _.bind
• Lodash supports implicit chaining, lazy chaining, & shortcut fusion
• Lodash split its overloaded _.head, _.last, _.rest, & _.initial out into
  _.take, _.takeRight, _.drop, & _.dropRight
  (i.e. _.head(array, 2) in Underscore.js is _.take(array, 2) in Lodash)

For Next button you can use xpath or cssSelector as below:

xpath for Next button: //input[@value='Next']

cssPath for Next button: input[value=Next]

you have to be careful because reseved words are not only for table names, also you have to check column names, my mistake was that one of my columns was named "user". If you are using PostgreSQL the correct dialect is: org.hibernate.dialect.PostgreSQLDialect

cheers.

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

The below css works for both Chrome and Firefox

input[type=number]::-webkit-outer-spin-button,
input[type=number]::-webkit-inner-spin-button {
    -webkit-appearance: none;
    margin: 0;
}

input[type=number] {
    -moz-appearance:textfield;
}

Tensorflow 2.x Compatible Answer: Converting mrry's code to Tensorflow 2.x (>= 2.0) for the benefit of the community.

!pip install tensorflow==2.1
import tensorflow as tf

tf.compat.v1.disable_eager_execution()    

t = tf.constant(42.0)
sess = tf.compat.v1.Session()
with sess.as_default():   # or `with sess:` to close on exit
    assert sess is tf.compat.v1.get_default_session()
    assert t.eval() == sess.run(t)

#The most important difference is that you can use sess.run() to fetch the values of many tensors in the same step:

t = tf.constant(42.0)
u = tf.constant(37.0)
tu = tf.multiply(t, u)
ut = tf.multiply(u, t)
with sess.as_default():
   tu.eval()  # runs one step
   ut.eval()  # runs one step
   sess.run([tu, ut])  # evaluates both tensors in a single step

Copy the value of path to notepad and check if this corresponds with the echo %path% in terminal window and make changes if needed. Then delete the old path value and paste the notepad value back in. I assume some invisible character entered there by some installation corrupted the path value.

I suggest simply to use the class text-center:

<body class="container">
    <div class="col-md-12 text-center">
        <img data-src="holder.js/100x100" alt="" />
    </div>
</body>

Just wanted to point out that the accepted answer has a couple of limitations (which I discovered when I tried to use it)

1. As written, it actually keeps recalculating the font size based on a ratio of the previous font size... thus after just a couple of calls it has rendered the font size as much too large. (eg Start with 12 point as your DESIGNED Font, expand the label by just 1 pixel, and the published code will calculate the Font size as 12 * (say) 1.2 (ratio of field space to text) = 14.4 or 14 point font. 1 more Pixel and call and you are at 16 point !).

It is thus not suitable (without adaptation) for use in a repeated-call setting (eg a ComponentResizedListener, or a custom/modified LayoutManager).

The listed code effectively assumes a starting size of 10 pt but refers to the current font size and is thus suitable for calling once (to set the size of the font when the label is created). It would work better in a multi-call environment if it did int newFontSize = (int) (widthRatio * 10); rather than int newFontSize = (int)(labelFont.getSize() * widthRatio);

2. Because it uses new Font(labelFont.getName(), Font.PLAIN, fontSizeToUse)) to generate the new font, there is no support for Bolding, Italic or Color etc from the original font in the updated font. It would be more flexible if it made use of labelFont.deriveFont instead.

3. The solution does not provide support for HTML label Text. (I know that was probably not ever an intended outcome of the answer code offered, but as I had an HTML-text JLabel on my JPanel I formally discovered the limitation. The FontMetrics.stringWidth() calculates the text length as inclusive of the width of the html tags - ie as simply more text)

I recommend looking at the answer to this SO question where trashgod's answer points to a number of different answers (including this one) to an almost identical question. On that page I will provide an additional answer that speeds up one of the other answers by a factor of 30-100.

In Netbeans 8.2

1. Dowload the binaries from the web source. The Apache Commos are in: [http://commons.apache.org/components.html][1] In this case, you must select the "Logging" in the Components menu and follow the link to downloads in the Releases part. Direct URL: [http://commons.apache.org/proper/commons-logging/download_logging.cgi][2] For me, the correct download was the file: commons-logging-1.2-bin.zip from the Binaries.

2. Unzip downloaded content. Now, you can see several jar files inside the directory created from the zip file.

3. Add the library to the project. Right click in the project, select Properties and click in Libraries (in the left side). Click the button "Add Jar/Folder". Go to the previously unzipped contents and select the properly jar file. Clic in "Open" and click in"Ok". The library has been loaded!

In Jakub Šturc's answer his #5 about passing data between contructors probably could use a little explanation. This is in overloading constructors and is the one case where use of this is mandatory. In the following example we can call the parameterized constructor from the parameterless constructor with a default parameter.

class MyClass {
    private int _x
    public MyClass() : this(5) {}
    public MyClass(int v) { _x = v;}
}

I've found this to be a particularly useful feature on occasion.

For me, I forgot to add the default serial id.

private static final long serialVersionUID = 1L;

Short Answer:

You likely want to use gpg instead of openssl so see "Additional Notes" at the end of this answer. But to answer the question using openssl:

To Encrypt:

openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.data

To Decrypt:

openssl enc -d -aes-256-cbc -in encrypted.data -out un_encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

Long Answer:

Your best source of information for openssl enc would probably be: https://www.openssl.org/docs/man1.1.1/man1/enc.html

Command line: openssl enc takes the following form:

openssl enc -ciphername [-in filename] [-out filename] [-pass arg]
[-e] [-d] [-a/-base64] [-A] [-k password] [-kfile filename] 
[-K key] [-iv IV] [-S salt] [-salt] [-nosalt] [-z] [-md] [-p] [-P] 
[-bufsize number] [-nopad] [-debug] [-none] [-engine id]

Explanation of most useful parameters with regards to your question:

-e
    Encrypt the input data: this is the default.

-d    
    Decrypt the input data.

-k <password>
    Only use this if you want to pass the password as an argument. 
    Usually you can leave this out and you will be prompted for a 
    password. The password is used to derive the actual key which 
    is used to encrypt your data. Using this parameter is typically
    not considered secure because your password appears in 
    plain-text on the command line and will likely be recorded in 
    bash history.

-kfile <filename>
    Read the password from the first line of <filename> instead of
    from the command line as above.

-a
    base64 process the data. This means that if encryption is taking 
    place the data is base64 encoded after encryption. If decryption 
    is set then the input data is base64 decoded before being 
    decrypted.
    You likely DON'T need to use this. This will likely increase the
    file size for non-text data. Only use this if you need to send 
    data in the form of text format via email etc.

-salt
    To use a salt (randomly generated) when encrypting. You always
    want to use a salt while encrypting. This parameter is actually
    redundant because a salt is used whether you use this or not 
    which is why it was not used in the "Short Answer" above!

-K key    
    The actual key to use: this must be represented as a string
    comprised only of hex digits. If only the key is specified, the
    IV must additionally be specified using the -iv option. When 
    both a key and a password are specified, the key given with the
    -K option will be used and the IV generated from the password 
    will be taken. It probably does not make much sense to specify 
    both key and password.

-iv IV
    The actual IV to use: this must be represented as a string 
    comprised only of hex digits. When only the key is specified 
    using the -K option, the IV must explicitly be defined. When a
    password is being specified using one of the other options, the 
    IV is generated from this password.

-md digest
    Use the specified digest to create the key from the passphrase.
    The default algorithm as of this writing is sha-256. But this 
    has changed over time. It was md5 in the past. So you might want
    to specify this parameter every time to alleviate problems when
    moving your encrypted data from one system to another or when
    updating openssl to a newer version.

Additional Notes:

Though you have specifically asked about OpenSSL you might want to consider using GPG instead for the purpose of encryption based on this article OpenSSL vs GPG for encrypting off-site backups?

To use GPG to do the same you would use the following commands:

To Encrypt:

gpg --output encrypted.data --symmetric --cipher-algo AES256 un_encrypted.data

To Decrypt:

gpg --output un_encrypted.data --decrypt encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

UPDATE: By version 41 of Google Chrome, initMouseEvent seemed to have a changed behavior.

this can be done by simulating ctrl + click (or any other key/event combinations that open a background tab) on a dynamically generated a element with its href attribute set to the desired url

In action: fiddle

function openNewBackgroundTab(){
    var a = document.createElement("a");
    a.href = "http://www.google.com/";
    var evt = document.createEvent("MouseEvents");
    //the tenth parameter of initMouseEvent sets ctrl key
    evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0,
                                true, false, false, false, 0, null);
    a.dispatchEvent(evt);
}

tested only on chrome

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

Note that events may be attached to the document itself rather than the element in question. In that case, you'll want to use:

$._data( $(document)[0], "events" );

And find the event with the correct selector:

And then look at the handler > [[FunctionLocation]]

Only this worked for me:

#container:hover .cube { background-color: yellow; }

Where .cube is CssClass of the #cube.

Create a uuid and also insert it to a column. Then you can easily identify your row with the uuid. Thats the only 100% working solution you can implement. All the other solutions are too complicated or are not working in same edge cases. E.g.:

1) Create row

INSERT INTO table (uuid, name, street, zip) 
        VALUES ('2f802845-447b-4caa-8783-2086a0a8d437', 'Peter', 'Mainstreet 7', '88888');

2) Get created row

SELECT * FROM table WHERE uuid='2f802845-447b-4caa-8783-2086a0a8d437';

I would suggest reading PEP 483 and PEP 484 and watching this presentation by Guido on type hinting.

In a nutshell: Type hinting is literally what the words mean. You hint the type of the object(s) you're using.

Due to the dynamic nature of Python, inferring or checking the type of an object being used is especially hard. This fact makes it hard for developers to understand what exactly is going on in code they haven't written and, most importantly, for type checking tools found in many IDEs (PyCharm and PyDev come to mind) that are limited due to the fact that they don't have any indicator of what type the objects are. As a result they resort to trying to infer the type with (as mentioned in the presentation) around 50% success rate.

To take two important slides from the type hinting presentation:

Why type hints?

1. Helps type checkers: By hinting at what type you want the object to be the type checker can easily detect if, for instance, you're passing an object with a type that isn't expected.
2. Helps with documentation: A third person viewing your code will know what is expected where, ergo, how to use it without getting them TypeErrors.
3. Helps IDEs develop more accurate and robust tools: Development Environments will be better suited at suggesting appropriate methods when know what type your object is. You have probably experienced this with some IDE at some point, hitting the . and having methods/attributes pop up which aren't defined for an object.

Why use static type checkers?

• Find bugs sooner: This is self-evident, I believe.
• The larger your project the more you need it: Again, makes sense. Static languages offer a robustness and control that dynamic languages lack. The bigger and more complex your application becomes the more control and predictability (from a behavioral aspect) you require.
• Large teams are already running static analysis: I'm guessing this verifies the first two points.

As a closing note for this small introduction: This is an optional feature and, from what I understand, it has been introduced in order to reap some of the benefits of static typing.

You generally do not need to worry about it and definitely don't need to use it (especially in cases where you use Python as an auxiliary scripting language). It should be helpful when developing large projects as it offers much needed robustness, control and additional debugging capabilities.

Type hinting with mypy:

In order to make this answer more complete, I think a little demonstration would be suitable. I'll be using mypy, the library which inspired Type Hints as they are presented in the PEP. This is mainly written for anybody bumping into this question and wondering where to begin.

Before I do that let me reiterate the following: PEP 484 doesn't enforce anything; it is simply setting a direction for function annotations and proposing guidelines for how type checking can/should be performed. You can annotate your functions and hint as many things as you want; your scripts will still run regardless of the presence of annotations because Python itself doesn't use them.

Anyways, as noted in the PEP, hinting types should generally take three forms:

• Function annotations (PEP 3107).
• Stub files for built-in/user modules.
• Special # type: type comments that complement the first two forms. (See: What are variable annotations? for a Python 3.6 update for # type: type comments)

Additionally, you'll want to use type hints in conjunction with the new typing module introduced in Py3.5. In it, many (additional) ABCs (abstract base classes) are defined along with helper functions and decorators for use in static checking. Most ABCs in collections.abc are included, but in a generic form in order to allow subscription (by defining a __getitem__() method).

For anyone interested in a more in-depth explanation of these, the mypy documentation is written very nicely and has a lot of code samples demonstrating/describing the functionality of their checker; it is definitely worth a read.

Function annotations and special comments:

First, it's interesting to observe some of the behavior we can get when using special comments. Special # type: type comments can be added during variable assignments to indicate the type of an object if one cannot be directly inferred. Simple assignments are generally easily inferred but others, like lists (with regard to their contents), cannot.

Note: If we want to use any derivative of containers and need to specify the contents for that container we must use the generic types from the typing module. These support indexing.

# Generic List, supports indexing.
from typing import List

# In this case, the type is easily inferred as type: int.
i = 0

# Even though the type can be inferred as of type list
# there is no way to know the contents of this list.
# By using type: List[str] we indicate we want to use a list of strings.
a = []  # type: List[str]

# Appending an int to our list
# is statically not correct.
a.append(i)

# Appending a string is fine.
a.append("i")

print(a)  # [0, 'i']

If we add these commands to a file and execute them with our interpreter, everything works just fine and print(a) just prints the contents of list a. The # type comments have been discarded, treated as plain comments which have no additional semantic meaning.

By running this with mypy, on the other hand, we get the following response:

(Python3)jimmi@jim: mypy typeHintsCode.py
typesInline.py:14: error: Argument 1 to "append" of "list" has incompatible type "int"; expected "str"

Indicating that a list of str objects cannot contain an int, which, statically speaking, is sound. This can be fixed by either abiding to the type of a and only appending str objects or by changing the type of the contents of a to indicate that any value is acceptable (Intuitively performed with List[Any] after Any has been imported from typing).

Function annotations are added in the form param_name : type after each parameter in your function signature and a return type is specified using the -> type notation before the ending function colon; all annotations are stored in the __annotations__ attribute for that function in a handy dictionary form. Using a trivial example (which doesn't require extra types from the typing module):

def annotated(x: int, y: str) -> bool:
    return x < y

The annotated.__annotations__ attribute now has the following values:

{'y': <class 'str'>, 'return': <class 'bool'>, 'x': <class 'int'>}

If we're a complete newbie, or we are familiar with Python 2.7 concepts and are consequently unaware of the TypeError lurking in the comparison of annotated, we can perform another static check, catch the error and save us some trouble:

(Python3)jimmi@jim: mypy typeHintsCode.py
typeFunction.py: note: In function "annotated":
typeFunction.py:2: error: Unsupported operand types for > ("str" and "int")

Among other things, calling the function with invalid arguments will also get caught:

annotated(20, 20)

# mypy complains:
typeHintsCode.py:4: error: Argument 2 to "annotated" has incompatible type "int"; expected "str"

These can be extended to basically any use case and the errors caught extend further than basic calls and operations. The types you can check for are really flexible and I have merely given a small sneak peak of its potential. A look in the typing module, the PEPs or the mypy documentation will give you a more comprehensive idea of the capabilities offered.

Stub files:

Stub files can be used in two different non mutually exclusive cases:

• You need to type check a module for which you do not want to directly alter the function signatures
• You want to write modules and have type-checking but additionally want to separate annotations from content.

What stub files (with an extension of .pyi) are is an annotated interface of the module you are making/want to use. They contain the signatures of the functions you want to type-check with the body of the functions discarded. To get a feel of this, given a set of three random functions in a module named randfunc.py:

def message(s):
    print(s)

def alterContents(myIterable):
    return [i for i in myIterable if i % 2 == 0]

def combine(messageFunc, itFunc):
    messageFunc("Printing the Iterable")
    a = alterContents(range(1, 20))
    return set(a)

We can create a stub file randfunc.pyi, in which we can place some restrictions if we wish to do so. The downside is that somebody viewing the source without the stub won't really get that annotation assistance when trying to understand what is supposed to be passed where.

Anyway, the structure of a stub file is pretty simplistic: Add all function definitions with empty bodies (pass filled) and supply the annotations based on your requirements. Here, let's assume we only want to work with int types for our Containers.

# Stub for randfucn.py
from typing import Iterable, List, Set, Callable

def message(s: str) -> None: pass

def alterContents(myIterable: Iterable[int])-> List[int]: pass

def combine(
    messageFunc: Callable[[str], Any],
    itFunc: Callable[[Iterable[int]], List[int]]
)-> Set[int]: pass

The combine function gives an indication of why you might want to use annotations in a different file, they some times clutter up the code and reduce readability (big no-no for Python). You could of course use type aliases but that sometime confuses more than it helps (so use them wisely).

This should get you familiarized with the basic concepts of type hints in Python. Even though the type checker used has been mypy you should gradually start to see more of them pop-up, some internally in IDEs (PyCharm,) and others as standard Python modules.

I'll try and add additional checkers/related packages in the following list when and if I find them (or if suggested).

Checkers I know of:

• Mypy: as described here.
• PyType: By Google, uses different notation from what I gather, probably worth a look.

Related Packages/Projects:

• typeshed: Official Python repository housing an assortment of stub files for the standard library.

The typeshed project is actually one of the best places you can look to see how type hinting might be used in a project of your own. Let's take as an example the __init__ dunders of the Counter class in the corresponding .pyi file:

class Counter(Dict[_T, int], Generic[_T]):
        @overload
        def __init__(self) -> None: ...
        @overload
        def __init__(self, Mapping: Mapping[_T, int]) -> None: ...
        @overload
        def __init__(self, iterable: Iterable[_T]) -> None: ...

Where _T = TypeVar('_T') is used to define generic classes. For the Counter class we can see that it can either take no arguments in its initializer, get a single Mapping from any type to an int or take an Iterable of any type.

Notice: One thing I forgot to mention was that the typing module has been introduced on a provisional basis. From PEP 411:

A provisional package may have its API modified prior to "graduating" into a "stable" state. On one hand, this state provides the package with the benefits of being formally part of the Python distribution. On the other hand, the core development team explicitly states that no promises are made with regards to the the stability of the package's API, which may change for the next release. While it is considered an unlikely outcome, such packages may even be removed from the standard library without a deprecation period if the concerns regarding their API or maintenance prove well-founded.

So take things here with a pinch of salt; I'm doubtful it will be removed or altered in significant ways, but one can never know.

^** Another topic altogether, but valid in the scope of type-hints: PEP 526: Syntax for Variable Annotations is an effort to replace # type comments by introducing new syntax which allows users to annotate the type of variables in simple varname: type statements.

See What are variable annotations?, as previously mentioned, for a small introduction to these.

in ruby for constantly using, add follow:

module Selenium
  module WebDriver
    class Element
      def select(value)
        self.find_elements(:tag_name => "option").find do |option|
          if option.text == value
            option.click
              return
           end
       end
    end
  end
end

and you will be able to select value:

browser.find_element(:xpath, ".//xpath").select("Value")

In my case it was very weird (use a storyboard): For some reason it changed from "Main storyboard file base name" to "Main nib file base name" in the plist.

Changing back to "Main storyboard file base name" (UIMainStoryboardFile) solved the issue

    var fileInput = $('.upload-file');
    var maxSize = fileInput.data('max-size');

If you want to set color for an individual menu item, customizing a toolbar theme is not the right solution. To achieve this, you can make use of android:actionLayout and an action view for the menu item.

First create an XML layout file for the action view. In this example we use a button as an action view:

menu_button.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/menuButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Done"
        android:textColor="?android:attr/colorAccent"
        style="?android:attr/buttonBarButtonStyle"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

In the code snippet above, we use android:textColor="?android:attr/colorAccent" to customize button text color.

Then in your XML layout file for the menu, include app:actionLayout="@layout/menu_button" as shown below:

main_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/menuItem"
        android:title=""
        app:actionLayout="@layout/menu_button"
        app:showAsAction="always"/>
</menu>

Last override the onCreateOptionsMenu() method in your activity:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main_menu, menu);
    MenuItem item = menu.findItem(R.id.menuItem);
    Button saveButton = item.getActionView().findViewById(R.id.menuButton);
    saveButton.setOnClickListener(view -> {
        // Do something
    });
    return true;
}

...or fragment:

@Override
public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater){
    inflater.inflate(R.menu.main_menu, menu);
    MenuItem item = menu.findItem(R.id.menuItem);
    Button saveButton = item.getActionView().findViewById(R.id.menuButton);
    button.setOnClickListener(view -> {
        // Do something
    });
}

For more details on action views, see the Android developer guide.

<script type="text/javascript">
    $(document).ready(function () {
        $('#btnadd').on('click', function () {
            var n1 = parseInt($('#txtn1').val());
            var n2 = parseInt($('#txtn2').val());
            var r = n1 + n2;
            alert("sum of 2 No= " + r);
            return false;
        });
        $('#btnclear').on('click', function () {
            $('#txtn1').val('');
            $('#txtn2').val('');
            $('#txtn1').focus();
            return false;
        });
    });
</script>

For asp.net users, the .NET framework provides a class to create a content disposition header: System.Net.Mime.ContentDisposition

Basic usage:

var cd = new System.Net.Mime.ContentDisposition();
cd.FileName = "myFile.txt";
cd.ModificationDate = DateTime.UtcNow;
cd.Size = 100;
Response.AppendHeader("content-disposition", cd.ToString());

I was also searching same answer, because at some point of time I needed total_count with distinct values along with limit/offset.

Because it's little tricky to do- To get total count with distinct values along with limit/offset. Usually it's hard to get total count with limit/offset. Finally I got the way to do -

SELECT DISTINCT COUNT(*) OVER() as total_count, * FROM table_name limit 2 offset 0;

Query performance is also high.

For Eclipse: menu bar-> window -> show view then find "debug" option if not in list then select other ...

new window will open and then search using keyword "debug" -> select debug from list

it will added near console tab. use debug tab to terminate and remove previous executions. ( right clicking on executing process will show you many option including terminate)

Can't you just get the size/length of the set/array, generate a random number between 0 and the size/length, then call the element whose index matches that number? HashSet has a .size() method, I'm pretty sure.

In psuedocode -

function randFromSet(target){
 var targetLength:uint = target.length()
 var randomIndex:uint = random(0,targetLength);
 return target[randomIndex];
}

Try this: parseInt(jQuery.offset().top, 10)

I know the accepted answer is great but for anyone who is looking for a hover like feel you can use setTimeout on mouseover and save the handle in a map (of let's say list ids to setTimeout Handle). On mouseover clear the handle from setTimeout and delete it from the map

onMouseOver={() => this.onMouseOver(someId)}
onMouseOut={() => this.onMouseOut(someId)

And implement the map as follows:

onMouseOver(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = setTimeout(() => {
    scrollPreviewToComponentId(listId);
  }, 1000); // Replace 1000ms with any time you feel is good enough for your hover action
  this.hoverHandleMap[listId] = handle;
}

onMouseOut(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = this.hoverHandleMap[listId];
  clearTimeout(handle);
  delete this.hoverHandleMap[listId];
}

And the map is like so,

hoverHandleMap: { [listId: string]: NodeJS.Timeout } = {};

I prefer onMouseOver and onMouseOut because it also applies to all the children in the HTMLElement. If this is not required you may use onMouseEnter and onMouseLeave respectively.

I Didn't have a /data/db directory. I created one and gave a chmod 777 permission and it worked for me

In your case you need to

1. Fix the ImageView's size. You need to use dp unit so that it will look the same in all devices.
2. Set android:scaleType to fitXY

Below is an example:

<ImageView
    android:id="@+id/photo"
    android:layout_width="200dp"
    android:layout_height="100dp"
    android:src="@drawable/iclauncher" 
    android:scaleType="fitXY"/>

For more information regarding ImageView scaleType please refer to the developer website.

Here is my solution. It uses AnimatorSet. AnimationSet library was too buggy to get working. This provides seamless and infinite transitions between fade in and out.

public static void setAlphaAnimation(View v) {
    ObjectAnimator fadeOut = ObjectAnimator.ofFloat(v, "alpha",  1f, .3f);
    fadeOut.setDuration(2000);
    ObjectAnimator fadeIn = ObjectAnimator.ofFloat(v, "alpha", .3f, 1f);
    fadeIn.setDuration(2000);

    final AnimatorSet mAnimationSet = new AnimatorSet();

    mAnimationSet.play(fadeIn).after(fadeOut);

    mAnimationSet.addListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
            mAnimationSet.start();
        }
    });
    mAnimationSet.start();
}

Here is the one liner i use, from terminal, to test the content of yml file(s):

$ ruby  -r yaml -r pp  -e 'pp YAML.load_file("/Users/za/project/application.yml")'
{"logging"=>
  {"path"=>"/var/logs/",
   "file"=>"TacoCloud.log",
   "level"=>
    {"root"=>"WARN", "org"=>{"springframework"=>{"security"=>"DEBUG"}}}}}

You should avoid using nested selects and I would go as far to say you should never use them in the actual select part of your statement. You will be running that select for each row that is returned. This is a really expensive operation. Rather use joins. It is much more readable and the performance is much better.

In your case the query below should help. Note the cases statement is still there, but now it is a simple compare operation.

select
    p.product_id,
    p.type_id,
    p.product_name,
    p.type,
    case p.type_id when 10 then (CONCAT_WS(' ' , first_name, middle_name, last_name )) else (null) end artistC
from
    Product p

    inner join Product_Type pt on
        pt.type_id = p.type_id

    left join Product_ArtistAuthor paa on
        paa.artist_id = p.artist_id
where
    p.product_id = $pid

I used a left join since I don't know the business logic.

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

One possible way to achieve this is to have static instances of a class within another class. For example:

class SystemParams
{
  pageWidth:  number = 8270;
  pageHeight: number = 11690;  
}

class DocLevelParams
{
  totalPages: number = 0;
}

class Wrapper
{ 
  static System: SystemParams = new SystemParams();
  static DocLevel: DocLevelParams = new DocLevelParams();
}

Then parameters can be accessed using Wrapper, without having to declare an instance of it. For example:

Wrapper.System.pageWidth = 1234;
Wrapper.DocLevel.totalPages = 10;

So you get the benefits of the JavaScript type object (as described in the original question) but with the benefits of being able to add the TypeScript typing. Additionally, it avoids having to add 'static' in front of all the parameters in the class.

This should do it:

^\S*

Try this query:

  select id,user, max(time), io 
  FROM lms_attendance group by user;

I stumbled across the issue now, too. The application defined a pure virtual interface class and a user-defined class provided through a shared lib was supposed to implement the interface. When linking the application, the linker complained that the shared lib would not provide vtable and type_info for the base class, nor could they be found anywhere else. Turned out that I simply forgot to make one of the interface's methods pure virtual (i.e. omitted the " = 0" at the end of the declaration. Very rudimentary, still easy to overlook and puzzling if you can't connect the linker diagnostic to the root cause.

How about an extension method that doesn't use regex.

If you do stick to one of the Regex options at least use RegexOptions.Compiled in the static variable.

public static string ToDigitsOnly(this string input)
{
    return new String(input.Where(char.IsDigit).ToArray());
}

This builds on Usman Zafar's answer converted to a method group.

I find it quite remarkable that out of 6 answers, none of them have mentioned the real source of the problem.

Collapsing margins on the last p inside #fw-footer is where that extra space is originating from.

A sensible fix would be to add overflow: hidden to #fw-footer (or simply add margin: 0 on the last p).

You could also just move the script inside that last p outside of the p, and then remove the p entirely; there's no need to wrap a script in a p. The first p (#fw-foottext) has margin: 0 applied, so the problem won't happen with that one.

As an aside, you've broken the fix I gave you in this question:

CSS3 gradient background with unwanted white space at bottom

You need html { height: 100% } and body { min-height: 100% }.

At the moment, you have html { height: auto } being applied, which does not work:

(This happens with a window taller than the content on the page)

var numbers = sNumbers.Split(',').Select(Int32.Parse).ToList();

You can use .append() for simply concatenating strings.

std::string s = "string1";
s.append("string2");

I think you might even be able to do:

std::string s = "string1";
s += "string2";

As for the formatting operations of C#'s StringBuilder, I believe snprintf (or sprintf if you want to risk writing buggy code ;-) ) into a character array and convert back to a string is about the only option.

If you don't care about the changes that git says are outstanding, then you can do a force checkout.

git checkout -f {{insert your branch name here}}

In .net VB - you could achieve control over columns and rows with the following in your razor file:

@Html.EditorFor(Function(model) model.generalNotes, New With {.htmlAttributes = New With {.class = "someClassIfYouWant", .rows = 5,.cols=6}})

I had a similar issue where one of the arrays was modified. I was using it for $httpBackend, and the returned object from that was actually a $promise object containing the array (not an Array object).

You can create a jasmine matcher to match the array by creating a toBeArray function:

beforeEach(function() {
  'use strict';
  this.addMatchers({
    toBeArray: function(array) {
      this.message = function() {
        return "Expected " + angular.mock.dump(this.actual) + " to be array " + angular.mock.dump(array) + ".";
      };
      var arraysAreSame = function(x, y) {
         var arraysAreSame = true;
         for(var i; i < x.length; i++)
            if(x[i] !== y[i])
               arraysAreSame = false;
         return arraysAreSame;
      };
      return arraysAreSame(this.actual, array);
    }
  });
});

And then just use it in your tests like the other jasmine matchers:

it('should compare arrays properly', function() {
  var array1, array2;
  /* . . . */
  expect(array1[0]).toBe(array2[0]);
  expect(array1).toBeArray(array2);
});

Just use

document.getElementById('submitbutton').disabled = !cansubmit;

instead of the the if-clause that works only one-way.

Also, for the users who have JS disabled, I'd suggest to set the initial disabled by JS only. To do so, just move the script behind the <form> and call checkform(); once.

For ASP.NET 1.1, this is still due to someone posting more than 1000 form fields, but the setting must be changed in the registry rather than a config file. It should be added as a DWORD named MaxHttpCollectionKeys in the registry under

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\1.1.4322.0

for 32-bit editions of Windows, and

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET\1.1.4322.0

for 64-bit editions of Windows.

next() can read the input only till the space. It can't read two words separated by space. Also, next() places the cursor in the same line after reading the input.

nextLine() reads input including space between the words (that is, it reads till the end of line \n). Once the input is read, nextLine() positions the cursor in the next line.

for reading the entire line you can use nextLine()

git stash pop

will get everything back in place

as suggested in the comments, you can use git stash branch newbranch to apply the stash to a new branch, which is the same as running:

git checkout -b newbranch
git stash pop

mbstring is a "non-default" extension, that is not enabled by default ; see this page of the manual :

Installation

mbstring is a non-default extension. This means it is not enabled by default. You must explicitly enable the module with the configure option. See the Install section for details

So, you might have to enable that extension, modifying the php.ini file (and restarting Apache, so your modification is taken into account)

I don't use CentOS, but you may have to install the extension first, using something like this (see this page, for instance, which seems to give a solution) :

yum install php-mbstring

(The package name might be a bit different ; so, use yum search to get it :-) )

I want to suggest a common solution for those requirements, maybe it is a use for you: AutoIt. With that program, you can write scripts on top of any window like Putty and execute all commands you want to (like button pressing or mouse clicking in textboxes or buttons).

This way you can emulate all steps you are always doing with Putty.

Use Hibernate.initialize() within @Transactional to initialize lazy objects.

 start Transaction 
      Hibernate.initialize(entity.getAddresses());
      Hibernate.initialize(entity.getPersons());
 end Transaction 

Now out side of the Transaction you are able to get lazy objects.

entity.getAddresses().size();
entity.getPersons().size();

In my case, the issue was new sites had an implicit deny of all IP addresses unless an explicit allow was created. To fix: Under the site in Features View: Under the IIS Section > IP Address and Domain Restrictions > Edit Feature Settings > Set 'Access for unspecified clients:' to 'Allow'

A few years late but hopefully this will help someone else...

1) First make sure the EC2 instance has a public IP. If has a Public DNS or Public IP address (circled below) then you should be good. This will be the address you ping.

2) Next make sure the Amazon network rules allow Echo Requests. Go to the Security Group for the EC2.

• right click, select inbound rules
• A: select Add Rule
• B: Select Custom ICMP Rule - IPv4
• C: Select Echo Request
• D: Select either Anywhere or My IP
• E: Select Save

3) Next, Windows firewall blocks inbound Echo requests by default. Allow Echo requests by creating a windows firewall exception...

• Go to Start and type Windows Firewall with Advanced Security
• Select inbound rules

4) Done! Hopefully you should now be able to ping your server.

You can do :

df['industry'] = 'yyy'

I would have written:

percent = 100
while True:
     try:
        pyc = int(input('enter pyc :'))
        tpy = int(input('enter tpy:'))
        percent = (pyc / tpy) * percent
        break
     except ZeroDivisionError as detail:
        print 'Handling run-time error:', detail

It's a list of public objects of that module, as interpreted by import *. It overrides the default of hiding everything that begins with an underscore.

I had a instance of an emulator running and a device connected.

When I ran command `adb -d uninstall PACKAGE_NAME', I got an error 'DELETE_FAILED_INTERNAL_ERROR' but when I killed the Emulator instance, I got a 'success' in un-installation process.

The following kills all the processes created by this user:

kill  -9  -1

Python 2:

• raw_input() takes exactly what the user typed and passes it back as a string.

• input() first takes the raw_input() and then performs an eval() on it as well.

The main difference is that input() expects a syntactically correct python statement where raw_input() does not.

Python 3:

• raw_input() was renamed to input() so now input() returns the exact string.
• Old input() was removed.

If you want to use the old input(), meaning you need to evaluate a user input as a python statement, you have to do it manually by using eval(input()).

Try doing this. Works for IE8, FF3.6, Chrome

<body>
  <table>
    <tr>
      <td>
        <div style="word-wrap: break-word; width: 100px">gdfggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg</div>

If week 1 always starts on the first Monday of the month try this formula for week number

=INT((6+DAY(A1+1-WEEKDAY(A1-1)))/7)

That gets the week number from the date in A1 with no intermediate calculations - if you want to use your "Monday's date" in B1 you can use this version

=INT((DAY(B1)+6)/7)

static and class both associate a method with a class, rather than an instance of a class. The difference is that subclasses can override class methods; they cannot override static methods.

class properties will theoretically function in the same way (subclasses can override them), but they're not possible in Swift yet.

I used the strip function to get rid of newline character as split lines was throwing memory errors on 4 gb File.

Sample Code:

with open('C:\\aapl.csv','r') as apple:
    for apps in apple.readlines():
        print(apps.strip())

Try this:

colnames(DF) = DF[1, ] # the first row will be the header
DF = DF[-1, ]          # removing the first row.

However, get a look if the data has been properly read. If you data.frame has numeric variables but the first row were characters, all the data has been read as character. To avoid this problem, it's better to save the data and read again with header=TRUE as you suggest. You can also get a look to this question: Reading a CSV file organized horizontally.

The answer should be Jain. You can not select an element via pseudo-selector, but you can add a new rule to your stylesheet with insertRule.

I made something that should work for you:

var addRule = function(sheet, selector, styles) {
    if (sheet.insertRule) return sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
    if (sheet.addRule) return sheet.addRule(selector, styles);
};

addRule(document.styleSheets[0], "body:before", "content: 'foo'");

    window.addRule = function (selector, styles, sheet) {

        styles = (function (styles) {
            if (typeof styles === "string") return styles;
            var clone = "";
            for (var p in styles) {
                if (styles.hasOwnProperty(p)) {
                    var val = styles[p];
                    p = p.replace(/([A-Z])/g, "-$1").toLowerCase(); // convert to dash-case
                    clone += p + ":" + (p === "content" ? '"' + val + '"' : val) + "; ";
                }
            }
            return clone;

The usage is quite simple:

$("body:after").addRule({
    content: "foo",
    color: "red",
    fontSize: "32px"
});

// or without jquery
addRule("body:after", {
    content: "foo",
    color: "red",
    fontSize: "32px"
});

If you don't need the output in real time (i.e. as the program is writing it) you could add

type windows-dir.txt

after that line.

The correct value for the content attribute should include initial-scale instead:

<meta name="viewport" content="width=device-width, initial-scale=1">_x000D_
                                                   ^^^^^^^^^^^^^^^

Apache FileUtil gives very handy methods to do the conversion

try {
    File file = new File(imagefilePath);
    byte[] byteArray = new byte[file.length()]();
    byteArray = FileUtils.readFileToByteArray(file);  
 }catch(Exception e){
     e.printStackTrace();

 }

Note for anybody who may have had problems with the cvWaitKey( ) function. If you are finding that cvWaitKey(x) is not waiting at all, make sure you actually have a window open (i.e. cvNamedWindow(...)). Put the cvNamedWindow(...) declaration BEFORE any cvWaitKey() function calls.

I assume that you're running a Linux, and you're using gEdit to edit your files. In the /etc/nginx/sites-enabled, it may have left a temp file e.g. default~ (watch the ~).

Depending on your editor, the file could be named .save or something like it. Just run $ ls -lah to see which files are unintended to be there and remove them (Thanks @Tisch for this).

Delete this file, and it will solve your problem.

Because @Robert K and @mattcasey both have good code, I thought I'd contribute here with a CoffeeScript version, in case anyone in the future could use it:

    String::unescape = (strict = false) ->
      ###
      # Take escaped text, and return the unescaped version
      #

You need to tell SQLPlus which database you want to log on to. Host String needs to be either a connection string or an alias configured in your TNSNames.ora file.

This work perfectly! ;)

This can be done using Ajax and with what I call: "a form mirror element". Instead to send a form with an element outside, you can create a fake form. The previous form is not needed.

<!-- This will do the trick -->
<div >
    <input id="mirror_element" type="text" name="your_input_name">
    <input type="button" value="Send Form">
</div>

Code ajax would be like:

    <script>
        ajax_form_mirror("#mirror_element", "your_file.php", "#your_element_response", "POST");

        function ajax_form_mirror(form, file, element, method) {
            $(document).ready(function() {
                // Ajax
                $(form).change(function() { // catch the forms submit event
                    $.ajax({                // create an AJAX call...
                        data: $(this).serialize(),      // get the form data
                        type: method,                   // GET or POST
                        url: file,                      // the file to call
                        success: function (response) {   // on success..
                        $(element).html(response);  // update the DIV
                        }
                    });

                    return false; // cancel original event to prevent form submitting
                });
            });
        }
   </script>

This is very usefull if you want to send some data inside another form without submit the parent form.

This code probably can be adapted/optimized according to the need. It works perfectly!! ;) Also works if you want a select option box like this:

<div>
    <select id="mirror_element" name="your_input_name">
        <option id="1" value="1">A</option>
        <option id="2" value="2">B</option>
        <option id="3" value="3">C</option>
        <option id="4" value="4">D</option>
    </select>
</div>

I hope it helped someone like it helped me. ;)

Just add <mvc:default-servlet-handler /> to your DispatcherServlet configuration and you are done!

Here, give this a shot (this is just a pseudocode)

using System;
using System.Data;
using System.Data.SqlClient;


public class PullDataTest
{
    // your data table
    private DataTable dataTable = new DataTable();

    public PullDataTest()

There are a couple of tree data structures in Java, such as DefaultMutableTreeNode in JDK Swing, Tree in Stanford parser package, and other toy codes. But none of these are sufficient yet small enough for general purpose.

Java-tree project attempts to provide another general-purpose tree data structure in Java. The difference between this and others are

• Totally free. You can use it anywhere (except in your homework :P)
• Small but general enough. I put everything of the data structure in one class file, so it would be easy to copy/paste.
• Not just a toys. I am aware of dozens of Java tree codes that can only handle binary trees or limited operations. This TreeNode is much more than that. It provides different ways of visiting nodes, such as preorder, postorder, breadthfirst, leaves, path to root, etc. Moreover, iterators are provided too for the sufficiency.
• More utils will be added. I am willing to add more operations to make this project comprehensive, especially if you send a request through github.

The problem is that salesAmount is being set to a string. If you enter the variable in the python interpreter and hit enter, you'll see the value entered surrounded by quotes. For example, if you entered 56.95 you'd see:

>>> sales_amount = raw_input("[Insert sale amount]: ")
[Insert sale amount]: 56.95
>>> sales_amount
'56.95'

You'll want to convert the string into a float before multiplying it by sales tax. I'll leave that for you to figure out. Good luck!

I had this error today and discovered it was an incorrectly-formatted year...

select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')

Notice the year has only three 'y's. It should have 4.

Double-check your format.

Some of the core differences between C# and Javascript script syntax in Unity.

    $(".glyphicon").click(function (e) {
        $(this).toggleClass("glyphicon glyphicon-chevron-up glyphicon glyphicon-chevron-down");

Hope this helps :D

Here is the step by step process to include php code in html file ( Tested )

If PHP is working there is only one step left to use PHP scripts in files with *.html or *.htm extensions as well. The magic word is ".htaccess". Please see the Wikipedia definition of .htaccess to learn more about it. According to Wikipedia it is "a directory-level configuration file that allows for decentralized management of web server configuration."

You can probably use such a .htaccess configuration file for your purpose. In our case you want the webserver to parse HTML files like PHP files.

First, create a blank text file and name it ".htaccess". You might ask yourself why the file name starts with a dot. On Unix-like systems this means it is a dot-file is a hidden file. (Note: If your operating system does not allow file names starting with a dot just name the file "xyz.htaccess" temporarily. As soon as you have uploaded it to your webserver in a later step you can rename the file online to ".htaccess") Next, open the file with a simple text editor like the "Editor" in MS Windows. Paste the following line into the file: AddType application/x-httpd-php .html .htm If this does not work, please remove the line above from your file and paste this alternative line into it, for PHP5: AddType application/x-httpd-php5 .html .htm Now upload the .htaccess file to the root directory of your webserver. Make sure that the name of the file is ".htaccess". Your webserver should now parse *.htm and *.html files like PHP files.

You can try if it works by creating a HTML-File like the following. Name it "php-in-html-test.htm", paste the following code into it and upload it to the root directory of your webserver:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
     <HTML>
 <HEAD>
 <TITLE>Use PHP in HTML files</TITLE>
 </HEAD>

   <BODY>
    <h1>
    <?php echo "It works!"; ?>
    </h1>
  </BODY>
 </HTML>

Try to open the file in your browser by typing in: http://www.your-domain.com/php-in-html-test.htm (once again, please replace your-domain.com by your own domain...) If your browser shows the phrase "It works!" everything works fine and you can use PHP in .*html and *.htm files from now on. However, if not, please try to use the alternative line in the .htaccess file as we showed above. If is still does not work please contact your hosting provider.

as simple as:

tmpHM.each{ key, value -> 
  doSomethingWithKeyAndValue key, value
}

You can check all the config settings using

git config --global --list

You can remove the setting for example username

git config --global --unset user.name

You can edit the configuration or remove the config setting manually by hand using:

git config --global --edit 

use this coding

io.sockets.on('connection', function (socket) {

    socket.on('mousemove', function (data) {

        socket.broadcast.emit('moving', data);
    });

this socket.broadcast.emit() will emit everthing in the function except to the server which is emitting

A command like the one below will show three sections: request headers, response headers and data (separated by CRLF). It avoids technical information and syntactical noise added by curl.

curl -vs www.stackoverflow.com 2>&1 | sed '/^* /d; /bytes data]$/d; s/> //; s/< //'

The command will produce the following output:

Situation: Working in my local branch, but I love to keep-up updates in the development branch named dev.

Solution: Usually, I prefer to do :

git fetch
git rebase origin/dev

There is another way to solve this, using a map:

vector<double> v = {...}; // input data
map<double, unsigned> m; // mapping from value to its index
for (auto it = v.begin(); it != v.end(); ++it)
    m[*it] = it - v.begin();

This will eradicate non-unique elements though. If that's not acceptable, use a multimap:

vector<double> v = {...}; // input data
multimap<double, unsigned> m; // mapping from value to its index
for (auto it = v.begin(); it != v.end(); ++it)
    m.insert(make_pair(*it, it - v.begin()));

In order to output the indices, iterate over the map or multimap:

for (auto it = m.begin(); it != m.end(); ++it)
    cout << it->second << endl;

Here's a concise solution:

_.differenceWith(a, b, _.isEqual);

Use CTRL+D at each line and it will find the matching words and select them then you can use multiple cursors.

You can also use find to find all the occurrences and then it would be multiple cursors too.

You have to just add the index_col=False parameter

df1 = pd.read_csv('foo.csv',
     header=0,
     index_col=False,
     names=["dummy", "date", "loc", "x"], 
     usecols=["dummy", "date", "loc", "x"],
     parse_dates=["date"])
  print df1

Do not use the ToList() method as in the accepted answer !

Running SQL profiler, I verified and found that ToList() function gets all the records from the database. It is really bad performance !!

I would have run this query by pure sql command as follows:

string query = "Update YourTable Set ... Where ...";    
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));

This would operate the update in one-shot without selecting even one row.

c_str() converts a C++ string into a C-style string which is essentially a null terminated array of bytes. You use it when you want to pass a C++ string into a function that expects a C-style string (e.g. a lot of the Win32 API, POSIX style functions, etc).

Here it is:

select player_name, player_salary, (player_salary * 1.1) as player_newsalary
from player 
order by player_name, player_salary, player_newsalary desc

You don't need to "group by" if there is only one instance of a player in the table.

It is going to write the value of your property model.Destination

This is by design. You'll want to populate your Destination property with the value you want in your controller before returning your view.

If you want to initialize a vector with numeric values other than zero, use rep

n <- 10
v <- rep(0.05, n)
v

which will give you:

[1] 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05

The threadunsafety of SimpleDateFormat should not be an issue if you just create it inside the very same method block as you use it. In other words, you are not assigning it as static or instance variable of a class and reusing it in one or more methods which can be invoked by multiple threads. Only this way the threadunsafety of SimpleDateFormat will be exposed. You can however safely reuse the same SimpleDateFormat instance within the very same method block as it would be accessed by the current thread only.

Also, the java.sql.Timestamp class which you're using there should not be abused as it's specific to the JDBC API in order to be able to store or retrieve a TIMESTAMP/DATETIME column type in a SQL database and convert it from/to java.util.Date.

So, this should do:

Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy h:mm:ss a");
String formattedDate = sdf.format(date);
System.out.println(formattedDate); // 12/01/2011 4:48:16 PM

I haven't been able to get good results from ImageMagick in this instance, but Inkscape does a nice job of scaling an SVG on Linux and Windows:

inkscape -z -w 1024 -h 1024 input.svg -e output.png

Note that you can omit one of the width/height parameters to have the other parameter scaled automatically based on the input image dimensions.

Edit (May 2020): Inkscape 1.0 users, please note that the command line arguments have changed:

inkscape -w 1024 -h 1024 input.svg -o output.png

Here's the result of scaling a 16x16 SVG to a 200x200 PNG using this command:

Just for reference, my Inkscape version (on Ubuntu 12.04) is:

Inkscape 0.48.3.1 r9886 (Mar 29 2012)

and on Windows 7, it is:

Inkscape 0.48.4 r9939 (Dec 17 2012)

The SQL in your SP is wrong. You probably want

Select @code = RecItemCode from Receipt where RecTransaction = @id

In your statement, you are not setting @code, you are trying to use it for the value of RecItemCode. This would explain your NullReferenceException when you try to use the output parameter, because a value is never assigned to it and you're getting a default null.

The other issue is that your SQL statement if rewritten as

Select @code = RecItemCode, RecUsername from Receipt where RecTransaction = @id

It is mixing variable assignment and data retrieval. This highlights a couple of points. If you need the data that is driving @code in addition to other parts of the data, forget the output parameter and just select the data.

Select RecItemCode, RecUsername from Receipt where RecTransaction = @id

If you just need the code, use the first SQL statement I showed you. On the offhand chance you actually need the output and the data, use two different statements

Select @code = RecItemCode from Receipt where RecTransaction = @id
Select RecItemCode, RecUsername from Receipt where RecTransaction = @id

This should assign your value to the output parameter as well as return two columns of data in a row. However, this strikes me as terribly redundant.

If you write your SP as I have shown at the very top, simply invoke cmd.ExecuteNonQuery(); and then read the output parameter value.

Another issue with your SP and code. In your SP, you have declared @code as varchar. In your code, you specify the parameter type as Int. Either change your SP or your code to make the types consistent.

Also note: If all you are doing is returning a single value, there's another way to do it that does not involve output parameters at all. You could write

 Select RecItemCode from Receipt where RecTransaction = @id

And then use object obj = cmd.ExecuteScalar(); to get the result, no need for an output parameter in the SP or in your code.

Ensure that JUnit.jar is in your classpath, then invoke the command line runner from the console

java org.junit.runner.JUnitCore [test class name]

Reference: junit FAQ

Put your JavaScript code after your tag <canvas></canvas>

You can also post multiple inputs with the same name and have them save into an array by adding empty square brackets to the input name like this:

<input type="text" name="comment[]" value="comment1"/>
<input type="text" name="comment[]" value="comment2"/>
<input type="text" name="comment[]" value="comment3"/>
<input type="text" name="comment[]" value="comment4"/>

If you use php:

print_r($_POST['comment']) 

you will get this:

Array ( [0] => 'comment1' [1] => 'comment2' [2] => 'comment3' [3] => 'comment4' )

Also, in PHP.INI file there is a setting:

max_input_vars

which in my version of PHP: 5.4.16 defaults to 1000.

From the manual: "How many input variables may be accepted (limit is applied to $_GET, $_POST and $_COOKIE superglobal separately)"

Ref.: http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars

Parallel GC

• XX:+UseParallelGC Use parallel garbage collection for scavenges. (Introduced in 1.4.1)
• XX:+UseParallelOldGC Use parallel garbage collection for the full collections. Enabling this option automatically sets -XX:+UseParallelGC. (Introduced in 5.0 update 6.)

UseParNewGC

UseParNewGC A parallel version of the young generation copying collector is used with the concurrent collector (i.e. if -XX:+ UseConcMarkSweepGC is used on the command line then the flag UseParNewGC is also set to true if it is not otherwise explicitly set on the command line).

Perhaps the easiest way to understand was combinations of garbage collection algorithms made by Alexey Ragozin

Conclusion:

1. Apply -XX:+UseParallelGC when you require parallel collection method over YOUNG generation ONLY, (but still) use serial-mark-sweep method as OLD generation collection
2. Apply -XX:+UseParallelOldGC when you require parallel collection method over YOUNG generation (automatically sets -XX:+UseParallelGC) AND OLD generation collection
3. Apply -XX:+UseParNewGC & -XX:+UseConcMarkSweepGC when you require parallel collection method over YOUNG generation AND require CMS method as your collection over OLD generation memory
4. You can't apply -XX:+UseParallelGC or -XX:+UseParallelOldGC with -XX:+UseConcMarkSweepGC simultaneously, that's why your require -XX:+UseParNewGC to be paired with CMS otherwise use -XX:+UseSerialGC explicitly OR -XX:-UseParNewGC if you wish to use serial method against young generation

A sort of block comment uses an if statement:

if(FALSE) {
  all your code
}

It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).

I think random.choice() is a better option.

import numpy as np

mylist = [13,23,14,52,6,23]

np.random.choice(mylist, 3, replace=False)

the function returns an array of 3 randomly chosen values from the list

you can set the width of right cell to minimum of required width, then apply overflow-hidden+text-overflow to the inside of left cell, but Firefox is buggy here...

although, seems, flexbox can help

You can write your own Extension method for type String :-

 public static string NonBlankValueOf(this string source)
 {
    return (string.IsNullOrEmpty(source)) ? "0" : source;
 }

Now you can use it like with any string type

FooTextBox.Text = strFoo.NonBlankValueOf();

In my app i wanted to display mulitple fb accounts of a user in a list, i wanted to show the login emails of fb accounts as a unique identifier of the respective accounts but i couldn't get it off from fb, all i got was the primary email in the user profile but in my case my login email and my primary email are different.

Here is how to to that:

The header and footer are 30px height.

The footer is stuck to the bottom of the page.

HTML:

<div id="header">
</div>
<div id="content">
</div>
<div id="footer">
</div>

CSS:

#header {
    height: 30px;
}
#footer {
    height: 30px;
    position: absolute;
    bottom: 0;
}
body {
    height: 100%;
    margin-bottom: 30px;
}

Factory and Service is a just wrapper of a provider.

Factory

Factory can return anything which can be a class(constructor function), instance of class, string, number or boolean. If you return a constructor function, you can instantiate in your controller.

 myApp.factory('myFactory', function () {

  // any logic here..

  // Return any thing. Here it is object
  return {
    name: 'Joe'
  }
}

Service

Service does not need to return anything. But you have to assign everything in this variable. Because service will create instance by default and use that as a base object.

myApp.service('myService', function () {

  // any logic here..

  this.name = 'Joe';
}

Actual angularjs code behind the service

function service(name, constructor) {
    return factory(name, ['$injector', function($injector) {
        return $injector.instantiate(constructor);
    }]);
}

It just a wrapper around the factory. If you return something from service, then it will behave like Factory.

IMPORTANT: The return result from Factory and Service will be cache and same will be returned for all controllers.

When should i use them?

Factory is mostly preferable in all cases. It can be used when you have constructor function which needs to be instantiated in different controllers.

Service is a kind of Singleton Object. The Object return from Service will be same for all controller. It can be used when you want to have single object for entire application. Eg: Authenticated user details.

If you want to check your URL. I suppose you are using Chrome. You can go to chrome console and URL will be displayed under "XHR finished loading:"

That's it. The 'else' block of a try-except clause exists for code that runs when (and only when) the tried operation succeeds. It can be used, and it can be abused.

try:
    fp= open("configuration_file", "rb")
except EnvironmentError:
    confdata= '' # it's ok if the file can't be opened
else:
    confdata= fp.read()
    fp.close()

# your code continues here
# working with (possibly empty) confdata

Personally, I like it and use it when appropriate. It semantically groups statements.

Test the return value of grep:

./somecommand | grep 'string' &> /dev/null
if [ $? == 0 ]; then
   echo "matched"
fi

which is done idiomatically like so:

if ./somecommand | grep -q 'string'; then
   echo "matched"
fi

and also:

./somecommand | grep -q 'string' && echo 'matched'

You can read about jQuery Ajax from official jQuery Site: https://api.jquery.com/jQuery.ajax/

If you don't want to use any click event then you can set timer for periodically update.

Below code may be help you just example.

function update() {
  $.get("response.php", function(data) {
    $("#some_div").html(data);
    window.setTimeout(update, 10000);
  });
}

Above function will call after every 10 seconds and get content from response.php and update in #some_div.

'Push' is for arrays.

You can do something like this:

app.js:

(function() {

var app = angular.module('myApp', []);

 app.controller('myController', ['$scope', function($scope) {

    $scope.myText = "Let's go";

    $scope.arrayText = [
            'Hello',
            'world'
        ];

    $scope.addText = function() {
        $scope.arrayText.push(this.myText);
    }

 }]);

})();

index.html

<!doctype html>
<html ng-app="myApp">
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
    <script src="app.js"></script>
  </head>
  <body>
    <div>
      <form ng-controller="myController" ng-submit="addText()">
           <input type="text" ng-model="myText" value="Lets go">
           <input type="submit" id="submit"/>
           <pre>list={{arrayText}}</pre>
      </form>
    </div>
  </body>
</html>

Use pickle, like this: import pickle

Your code would look like this:

import pickle
mybytes = [120, 3, 255, 0, 100]
with open("bytesfile", "wb") as mypicklefile:
    pickle.dump(mybytes, mypicklefile)

To read the data back, use the pickle.load method

    [HttpPost]
    public JsonResult DeleteCotnact(int id)
    {
        using (MycasedbEntities dbde = new MycasedbEntities())
        {
            Contact rowcontact = (from c in dbde.Contact
                                     where c.Id == id
                                     select c).FirstOrDefault();

            dbde.Contact.Remove(rowcontact);
            dbde.SaveChanges();

            return Json(id);
        }
    }

What do you think of this, simple or not, you could also try this:

        var productrow = cnn.Product.Find(id);
        cnn.Product.Remove(productrow);
        cnn.SaveChanges();

In response to jt. You are correct, the HTML with just the password is susceptible to the Man in the middle attack. However, you can seed it with a GUID from the server ...

$.post(
  'includes/login.php', 
  { user: username, pass: $.md5(password + GUID) },
   onLogin, 
  'json' );

This would defeat the Man-In-The middle ... in that the server would generate a new GUID for each attempt.

One thing that should be considered is licensing.

Notepad++ is free (as in speech and as in beer) for perpetual use, released under the GPL license, whereas Sublime Text 2 requires a license.

To quote the Sublime Text 2 website:

..a license must be purchased for continued use. There is currently no enforced time limit for the evaluation.

The same is now true of Sublime Text 3, and a paid upgrade will be needed for future versions.

Upgrade Policy A license is valid for Sublime Text 3, and includes all point updates, as well as access to prior versions (e.g., Sublime Text 2). Future major versions, such as Sublime Text 4, will be a paid upgrade.

This licensing requirement is still correct as of Dec 2019.

If when you set disabled="disabled" immediately after the user clicks the button, and the form doesn't submit because of that, you could try two things:

//First choice [given myForm = your form]:
myInputButton.disabled = "disabled";
myForm.submit()

//Second choice:
setTimeout(disableFunction, 1);  
//so the form will submit and then almost instantly, the button will be disabled  

Although I honestly bet there will be a better way to do this, than that.

HTML:

<div class="parent">
    <span id="mySpan">Something in English</span>
</div>

JQUERY

$('#mySpan').animate({'opacity': 0}, 400, function(){
        $(this).html('Something in Spanish').animate({'opacity': 1}, 400);    
    });

Live example

With Git there is no “correct” workflow. Use whatever floats your boat. However, if you constantly get conflicts when merging branches maybe you should coordinate your efforts better with your fellow developer(s)? Sounds like the two of you keep editing the same files. Also, watch out for whitespace and subversion keywords (i.e., “$Id$” and others).

One of recent the TFS Rocks pocasts mentioned such an organisation, may have been number 16.

Got it :D

function getContextPath() {
   return window.location.pathname.substring(0, window.location.pathname.indexOf("/",2));
}
alert(getContextPath());

Important note: Does only work for the "root" context path. Does not work with "subfolders", or if context path has a slash ("/") in it.

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

var uniqueColors = (from dbo in database.MainTable 
                    where dbo.Property == true
                    select dbo.Color.Name).Distinct();

It imports once when the function executes first time.

Pros:

• imports related to the function they're used in
• easy to move functions around the package

Cons:

• couldn't see what modules this module might depend on

After reading a bunch of people's comments online about this, my first reaction was that this is basically one of those really unimportant debates. However, my initial interest was to find out the right format so I could be consistent with my file naming practice.

Long story short, the creator of YAML are saying .yaml, but personally I keep doing .yml. That just makes more sense to me. So I went on the journey to find affirmation and soon enough, I realise that docker uses .yml everywhere. I've been writing docker-compose.yml files all this time, while you keep seeing in kubernetes' docs kubectl apply -f *.yaml...

So, in conclusion, both formats are obviously accepted and if you are on the other end, (ie: writing systems that receive a YAML file as input) you should allow for both. That seems like another snake case versus camel case thingy...

Create an URL object and append the values to seachParameters

let baseURL = "http://www.google.com/search";
let url = new URL(baseURL);
let params = url.searchParams;
    params.append("q","This is seach query");

console.log( url.toString() );

Get yesterday date in javascript

You have to run code and check it output

    var today = new Date();_x000D_
    var yesterday = new Date(today);_x000D_
    _x000D_
    yesterday.setDate(today.getDate() - 1);_x000D_
    console.log("Original Date : ",yesterday);_x000D_
_x000D_
    const monthNames = [_x000D_
  "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"_x000D_
];_x000D_
    var month = today.getMonth() + 1_x000D_
    yesterday = yesterday.getDate() + ' ' + monthNames[month] + ' ' + yesterday.getFullYear()_x000D_
   _x000D_
    console.log("Modify Date : ",yesterday);

This article describes how to render a View to a string in different scenarios:

1. MVC Controller calling another of its own ActionMethods
2. MVC Controller calling an ActionMethod of another MVC Controller
3. WebAPI Controller calling an ActionMethod of an MVC Controller

The solution/code is provided as a class called ViewRenderer. It is part of Rick Stahl's WestwindToolkit at GitHub.

Usage (3. - WebAPI example):

string html = ViewRenderer.RenderView("~/Areas/ReportDetail/Views/ReportDetail/Index.cshtml", ReportVM.Create(id));

You can use HttpPost, there are methods to add Header to the Request.

DefaultHttpClient httpclient = new DefaultHttpClient();
String url = "http://localhost";
HttpPost httpPost = new HttpPost(url);

httpPost.addHeader("header-name" , "header-value");

HttpResponse response = httpclient.execute(httpPost);

I tried one of the previous answers in a web app (actually an Azure web role running locally) and it didn't quite work. However, this similar approach did work:

var map = new ExeConfigurationFileMap { ExeConfigFilename = "MyComponent.dll.config" };
var path = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None).FilePath;

The config file turned out to be in C:\Program Files\IIS Express\MyComponent.dll.config. Interesting place for it.

Download grade files from this url and extract all in a folder:? https://gradle.org/releases

Open file -> Setting in windows OS or Preferences in mac OS and in "Build, Execution, Deployment"

Click on "Gradle"

Check “Use local cradle distribution” and give that extracted folder path.

Run gradle.bat for Windows OS and gradle file for mac OS in that folder.

Then check “Offline work”.

"your extracted folder path"/gradle-4.10.2/bin/.gradle (for version 4.1.2 you can set your version)

Press OK and enjoy it.

What about running tmux/GNU Screen within the container? Seems the smoother way to access as many vty as you want with a simple:

$ docker attach {container id}

Basically you need to do two loops here. The one you are doing already is iterating each element in the 0th array element.

You have programs: [ {...}, {...} ] so programs[0] is { "name":"zonealarm", "price":"500" } So your loop is just going over that.

You could do an outer loop over the array

$.each(data.programs, function(index) {

    // then loop over the object elements
    $.each(data.programs[index], function(key, value) {
        console.log(key + ": " + value);
    }

}

editText.setSelection is the magic here. Basically selection gives you place cursor at any position you want.

EditText editText = findViewById(R.id.editText);
editText.setSelection(editText.getText().length());

This places cursor to end of EditText. Basically editText.getText().length() gives you text length. Then you use setSelection with length.

editText.setSelection(0);

It is for setting cursor at start position (0).

You probably are going to want to use the following declaration:

height: 100%;

This will set the div's height to 100% of its containers height, which will make it fill the parent div.

you can use the following Bootstrap class with

<tr class="w-25">

</tr>

I ran into a similar issue when building a custom pagination for a site I am working on.

The global variable I created in functions.php was defined and set to 0. I could output this value in my javascript no problem using the method @Karsten outlined above. The issue was with updating the global variable that I initially set to 0 inside the PHP file.

Here is my workaround (hacky? I know!) but after struggling for an hour on a tight deadline the following works:

Inside archive-episodes.php:

<script>
    // We define the variable and update it in a php
    // function defined in functions.php
    var totalPageCount; 
</script>

Inside functions.php

<?php
    $totalPageCount = WP_Query->max_num_pages; // In my testing scenario this number is 8.
    echo '<script>totalPageCount = $totalPageCount;</script>';
?>

To keep it simple, I was outputting the totalPageCount variable in an $ajax.success callback via alert.

$.ajax({
        url: ajaxurl,
        type: 'POST',
        data: {"action": "infinite_scroll", "page_no": pageNumber, "posts_per_page": numResults},
        beforeSend: function() {
            $(".ajaxLoading").show();
        },
        success: function(data) {
                            //alert("DONE LOADING EPISODES");
            $(".ajaxLoading").hide();

            var $container = $("#episode-container");

            if(firstRun) {
                $container.prepend(data);
                initMasonry($container);
                ieMasonryFix();
                initSearch();
            } else {
                var $newItems = $(data);
                $container.append( $newItems ).isotope( 'appended', $newItems );
            }
            firstRun = false;

            addHoverState();                            
            smartResize();

            alert(totalEpiPageCount); // THIS OUTPUTS THE CORRECT PAGE TOTAL
        }

Be it as it may, I hope this helps others! If anyone has a "less-hacky" version or best-practise example I'm all ears.

dplyr since 0.4 implemented all those joins including outer_join, but it was worth noting that for the first few releases prior to 0.4 it used not to offer outer_join, and as a result there was a lot of really bad hacky workaround user code floating around for quite a while afterwards (you can still find such code in SO, Kaggle answers, github from that period. Hence this answer still serves a useful purpose.)

Join-related release highlights:

v0.5 (6/2016)

• Handling for POSIXct type, timezones, duplicates, different factor levels. Better errors and warnings.
• New suffix argument to control what suffix duplicated variable names receive (#1296)

v0.4.0 (1/2015)

• Implement right join and outer join (#96)
• Mutating joins, which add new variables to one table from matching rows in another. Filtering joins, which filter observations from one table based on whether or not they match an observation in the other table.

v0.3 (10/2014)

• Can now left_join by different variables in each table: df1 %>% left_join(df2, c("var1" = "var2"))

v0.2 (5/2014)

• *_join() no longer reorders column names (#324)

v0.1.3 (4/2014)

• has inner_join, left_join, semi_join, anti_join
• outer_join not implemented yet, fallback is use base::merge() (or plyr::join())
• didn't yet implement right_join and outer_join
• Hadley mentioning other advantages here
• one minor feature merge currently has that dplyr doesn't is the ability to have separate by.x,by.y columns as e.g. Python pandas does.

Workarounds per hadley's comments in that issue:

• right_join(x,y) is the same as left_join(y,x) in terms of the rows, just the columns will be different orders. Easily worked around with select(new_column_order)
• outer_join is basically union(left_join(x, y), right_join(x, y)) - i.e. preserve all rows in both data frames.

A lot of answers are recommending the following but if you read through the source of that script, you'll realise it's deprecated.

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

If your pip is also broken, this won't work either.

pip install setuptools

I found I had to run the command from Ensure pip, setuptools, and wheel are up to date, to get pip working again.

python -m pip install --upgrade pip setuptools wheel
