You probably do not want an explicit implementation of IEnumerable<T> (which is what you've shown).

The usual pattern is to use IEnumerable<T>'s GetEnumerator in the explicit implementation of IEnumerable:

class FooCollection : IEnumerable<Foo>, IEnumerable
{
    SomeCollection<Foo> foos;

    // Explicit for IEnumerable because weakly typed collections are Bad
    System.Collections.IEnumerator IEnumerable.GetEnumerator()
    {
        // uses the strongly typed IEnumerable<T> implementation
        return this.GetEnumerator();
    }

    // Normal implementation for IEnumerable<T>
    IEnumerator<Foo> GetEnumerator()
    {
        foreach (Foo foo in this.foos)
        {
            yield return foo;
            //nb: if SomeCollection is not strongly-typed use a cast:
            // yield return (Foo)foo;
            // Or better yet, switch to an internal collection which is
            // strongly-typed. Such as List<T> or T[], your choice.
        }

        // or, as pointed out: return this.foos.GetEnumerator();
    }
}

Here's one way. You have to get the individual components from the date object (day, month & year) and then build and format the string however you wish.

n =  new Date();_x000D_
y = n.getFullYear();_x000D_
m = n.getMonth() + 1;_x000D_
d = n.getDate();_x000D_
document.getElementById("date").innerHTML = m + "/" + d + "/" + y;

<p id="date"></p>

You can format them as table !!

form {_x000D_
  display: table;_x000D_
}_x000D_
label {_x000D_
  display: table-row;_x000D_
}_x000D_
input {_x000D_
  display: table-cell;_x000D_
}_x000D_
p1 {_x000D_
  display: table-cell;_x000D_
}

<div id="header_order_form" align="center">_x000D_
  <form id="order_header" method="post">_x000D_
    <label>_x000D_
      <p1>order_no:_x000D_

A simple getRowCount method can look like this :

private int getRowCount(ResultSet resultSet) {
    if (resultSet == null) {
        return 0;
    }

    try {
        resultSet.last();
        return resultSet.getRow();
    } catch (SQLException exp) {
        exp.printStackTrace();
    } finally {
        try {
            resultSet.beforeFirst();
        } catch (SQLException exp) {
            exp.printStackTrace();
        }
    }

    return 0;
}

Just to be aware that this method will need a scroll sensitive resultSet, so while creating the connection you have to specify the scroll option. Default is FORWARD and using this method will throw you exception.

I had this same problem and solved it by adding an event handler for the play action in addition to the click action. I hide the controls while playing to avoid the pause button issue.

    var v = document.getElementById('videoID');
    v.addEventListener(
       'play', 
          function() { 
             v.play();
          }, 
        false);

    v.onclick = function() {
      if (v.paused) {
        v.play();
        v.controls=null;
      } else {
        v.pause();
        v.controls="controls";
      }
    };

Seeking still acts funny though, but at least the confusion with the play control is gone. Hope this helps.

Anyone have a solution to that?

NOTICE: AS OF JULY 12TH, 2018, THE OTHER ANSWERS ARE ALL OUTDATED. JSONP IS NOW CONSIDERED A TERRIBLE IDEA

If you have your JSON as a string, JSON.parse() will work fine. Since you are loading the json from a file, you will need to do a XMLHttpRequest to it. For example (This is w3schools.com example):

var xmlhttp = new XMLHttpRequest();_x000D_
xmlhttp.onreadystatechange = function() {_x000D_
    if (this.readyState == 4 && this.status == 200) {_x000D_
        var myObj = JSON.parse(this.responseText);_x000D_
        document.getElementById("demo").innerHTML = myObj.name;_x000D_
    }_x000D_
};_x000D_
xmlhttp.open("GET", "json_demo.txt", true);_x000D_
xmlhttp.send();

<!DOCTYPE html>_x000D_
<html>_x000D_
<body>_x000D_
_x000D_
<h2>Use the XMLHttpRequest to get the content of a file.</h2>_x000D_
<p>The content is written in JSON format, and can easily be converted into a JavaScript object.</p>_x000D_
_x000D_
<p id="demo"></p>_x000D_
_x000D_
_x000D_
<p>Take a look at <a href="json_demo.txt" target="_blank">json_demo.txt</a></p>_x000D_
_x000D_
</body>_x000D_
</html>

It will not work here as that file isn't located here. Go to this w3schools example though: https://www.w3schools.com/js/tryit.asp?filename=tryjson_ajax

Here is the documentation for JSON.parse(): https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

Here's a summary:

The JSON.parse() method parses a JSON string, constructing the JavaScript value or object described by the string. An optional reviver function can be provided to perform a transformation on the resulting object before it is returned.

Here's the example used:

var json = '{"result":true, "count":42}';_x000D_
obj = JSON.parse(json);_x000D_
_x000D_
console.log(obj.count);_x000D_
// expected output: 42_x000D_
_x000D_
console.log(obj.result);_x000D_
// expected output: true

Here is a summary on XMLHttpRequests from https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest:

Use XMLHttpRequest (XHR) objects to interact with servers. You can retrieve data from a URL without having to do a full page refresh. This enables a Web page to update just part of a page without disrupting what the user is doing. XMLHttpRequest is used heavily in Ajax programming.

If you don't want to use XMLHttpRequests, then a JQUERY way (which I'm not sure why it isn't working for you) is http://api.jquery.com/jQuery.getJSON/

Since it isn't working, I'd try using XMLHttpRequests

You could also try AJAX requests:

$.ajax({
    'async': false,
    'global': false,
    'url': "/jsonfile.json",
    'dataType': "json",
    'success': function (data) {
        // do stuff with data
    }
});

Documentation: http://api.jquery.com/jquery.ajax/

• add ANSI color code to display the error message in red:

echoerr() { printf "\e[31;1m%s\e[0m\n" "$*" >&2; }

# if somehow \e is not working on your terminal, use \u001b instead
# echoerr() { printf "\u001b[31;1m%s\u001b[0m\n" "$*" >&2; }

echoerr "This error message should be RED"

If triangle.lborderA is indeed a long then the test in the original code is trivially true, and there is no way to test it. It is also useless.

However, if triangle.lborderA is a double, the comparison is useful and can be tested. isBiggerThanMaxLong(1e300) does return true.

  public static boolean isBiggerThanMaxLong(double in){
    return in > Long.MAX_VALUE;
  }

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

Try to encapsulate the ajax call into a function and set the async option to false. Note that this option is deprecated since jQuery 1.8.

function foo() {
    var myajax = $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        async: false, //add this
    });
    return myajax.responseText;
}

You can do this also:

$.ajax({
    type: "POST",
    url: "CHService.asmx/SavePurpose",
    dataType: "text",
    data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
    contentType: "application/json; charset=utf-8",
    async: false, //add this
}).done(function ( data ) {
        Success = true;
}).fail(function ( data ) {
       Success = false;
});

In the latest release of Google Play, Google removed the need to ask permission for internet as "most apps need it anyways nowadays". However, for users who have older versions, it is still recommended to leave the code below in your manifest

<uses-permission android:name="android.permission.INTERNET" /> 

You can use the IPython.display.clear_output to clear the output as mentioned in cel's answer. I would add that for me the best solution was to use this combination of parameters to print without any "shakiness" of the notebook:

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print(i, flush=True)

I converted @syockit's answer as well as the step-down approach into a reusable Angular service for anyone who's interested: https://gist.github.com/fisch0920/37bac5e741eaec60e983

I included both solutions because they both have their own pros / cons. The lanczos convolution approach is higher quality at the cost of being slower, whereas the step-wise downscaling approach produces reasonably antialiased results and is significantly faster.

Example usage:

angular.module('demo').controller('ExampleCtrl', function (imageService) {
  // EXAMPLE USAGE
  // NOTE: it's bad practice to access the DOM inside a controller, 
  // but this is just to show the example usage.

  // resize by lanczos-sinc filter
  imageService.resize($('#myimg')[0], 256, 256)
    .then(function (resizedImage) {
      // do something with resized image
    })

  // resize by stepping down image size in increments of 2x
  imageService.resizeStep($('#myimg')[0], 256, 256)
    .then(function (resizedImage) {
      // do something with resized image
    })
})

As @David Heffeman indicates the recommendation is to use .yaml when possible, and the recommendation has been that way since September 2006.

That some projects use .yml is mostly because of ignorance of the implementers/documenters: they wanted to use YAML because of readability, or some other feature not available in other formats, were not familiar with the recommendation and and just implemented what worked, maybe after looking at some other project/library (without questioning whether what was done is correct).

The best way to approach this is to be rigorous when creating new files (i.e. use .yaml) and be permissive when accepting input (i.e. allow .yml when you encounter it), possible automatically upgrading/correcting these errors when possible.

The other recommendation I have is to document the argument(s) why you have to use .yml, when you think you have to. That way you don't look like an ignoramus, and give others the opportunity to understand your reasoning. Of course "everybody else is doing it" and "On Google .yml has more pages than .yaml" are not arguments, they are just statistics about the popularity of project(s) that have it wrong or right (with regards to the extension of YAML files). You can try to prove that some projects are popular, just because they use a .yml extension instead of the correct .yaml, but I think you will be hard pressed to do so.

Some projects realize (too late) that they use the incorrect extension (e.g. originally docker-compose used .yml, but in later versions started to use .yaml, although they still support .yml). Others still seem ignorant about the correct extension, like AppVeyor early 2019, but allow you to specify the configuration file for a project, including extension. This allows you to get the configuration file out of your face as well as giving it the proper extension: I use .appveyor.yaml instead of appveyor.yml for building the windows wheels of my YAML parser for Python).

On the other hand:

The Yaml (sic!) component of Symfony2 implements a selected subset of features defined in the YAML 1.2 version specification.

So it seems fitting that they also use a subset of the recommended extension.

When a class implements an interface,it is creating instance for the interface members. While a static type doesnt have an instance,there is no point in having static signatures in an interface.

you can put all your controls to panel and then write a code to move your panel to center of your form.

panelMain.Location = 
    new Point(ClientSize.Width / 2 - panelMain.Size.Width / 2, 
              ClientSize.Height / 2 - panelMain.Size.Height / 2);

panelMain.Anchor = AnchorStyles.None;

For disk space, if you have Java 6, you can use the getTotalSpace and getFreeSpace methods on File. If you're not on Java 6, I believe you can use Apache Commons IO to get some of the way there.

I don't know of any cross platform way to get CPU usage or Memory usage I'm afraid.

Even I am using Java 7, maven 2.2.1 and was getting the same error, I removed <scope>tests</scope> from my pom and used

mvn clean -DskipTests=true install to successfully build my projects, without upgrading my maven version.

if you want to run spring boot without a servlet container, but with one on the classpath (e.g. for tests), use the following, as described in the spring boot documentation:

@Configuration
@EnableAutoConfiguration
public class MyClass{
    public static void main(String[] args) throws JAXBException {
                 SpringApplication app = new SpringApplication(MyClass.class);
         app.setWebEnvironment(false); //<<<<<<<<<
         ConfigurableApplicationContext ctx = app.run(args);
    }
}

also, I just stumbled across this property:

spring.main.web-environment=false

You can get the ROWID by using the methods given below :

1.Create a new table with auto increment field in it

2.Use Row_Number analytical function to get the sequence based on your requirement.I would prefer this because it helps in situations where you are you want the row_id on ascending or descending manner of a specific field or combination of fields

Sample:Row_Number() Over(Partition by Deptno order by sal desc)

Above sample will give you the sequence number based on highest salary of each department.Partition by is optional and you can remove it according to your requirements

This solution is from Beginning Hibernate book:

     Query<User> query = session.createQuery("from User u where u.scn=:scn", User.class);
     query.setParameter("scn", scn);
     User user = query.uniqueResult();

game.achievement This object type represents a specific achievement in a game. An app must be in the 'Games' category in App Dashboard to be able to use this object type. Every achievement has a game:points value associate with it. This is not related to the points the user has scored in the game, but is a way for the app to indicate the relative importance and scarcity of different achievements: * Each game gets a total of 1,000 points to distribute across its achievements * Each game gets a maximum of 1,000 achievements * Achievements which are scarcer and have higher point values will receive more distribution in Facebook's social channels. For example, achievements which have point values of less than 10 will get almost no distribution. Apps should aim for between 50-100 achievements consisting of a mix of 50 (difficult), 25 (medium), and 10 (easy) point value achievements Read more on how to use achievements in this guide.

If you're actually doing it just because you want to get the user's timezone then all you have to do is change your timezone in you config/applications.rb.

Like this:

Rails, by default, will save your time record in UTC even if you specify the current timezone.

config.time_zone = "Singapore"

So this is all you have to do and you're good to go.

This works for me

foreach ($photos_array as $photo) {

    //collect all inserted record IDs
    $photo_id_array[$photo->id] = ['type' => 'Offence'];  

}

//Insert into offence_photo table
$offence->photos()->sync($photo_id_array, false);//dont delete old entries = false

If you have specific chars should be:

Collection<Character> specificChars = Arrays.asList('A', 'D', 'E');  // more chars
char symbol = 'Y';
System.out.println(specificChars.contains(symbol));   // false
symbol = 'A';
System.out.println(specificChars.contains(symbol));   // true           

Date format is yyyy-mm-dd. So the above query is looking for records older than 12Apr2013

Suggest you do a quick check by setting the date string to '2013-04-30', if no sql error, date format is confirmed to yyyy-mm-dd.

I have an idea to use value of id() in logging.
It's cheap to get and it's quite short.
In my case I use tornado and id() would like to have an anchor to group messages scattered and mixed over file by web socket.

If just want to use Linq, you can override Equals and GetHashCode methods.

Product class:

public class Product
{
    public string ProductName { get; set; }
    public int Id { get; set; }


    public override bool Equals(object obj)
    {
        if (!(obj is Product))
        {
            return false;
        }

        var other = (Product)obj;
        return Id == other.Id;
    }

    public override int GetHashCode()
    {
        return Id.GetHashCode();
    }
}

Main Method:

static void Main(string[] args)
    {

        var products = new List<Product>
        {
            new Product{ ProductName="Product 1",Id = 1},
            new Product{ ProductName="Product 2",Id = 2},

How do I convert ElementTree.Element to a String?

For Python 3:

xml_str = ElementTree.tostring(xml, encoding='unicode')

For Python 2:

xml_str = ElementTree.tostring(xml, encoding='utf-8')

The following is compatible with both Python 2 & 3, but only works for Latin characters:

xml_str = ElementTree.tostring(xml).decode()

Example usage

from xml.etree import ElementTree

xml = ElementTree.Element("Person", Name="John")
xml_str = ElementTree.tostring(xml).decode()
print(xml_str)

Output:

<Person Name="John" />

Explanation

Despite what the name implies, ElementTree.tostring() returns a bytestring by default in Python 2 & 3. This is an issue in Python 3, which uses Unicode for strings.

In Python 2 you could use the str type for both text and binary data. Unfortunately this confluence of two different concepts could lead to brittle code which sometimes worked for either kind of data, sometimes not. [...]

To make the distinction between text and binary data clearer and more pronounced, [Python 3] made text and binary data distinct types that cannot blindly be mixed together.

^{Source: Porting Python 2 Code to Python 3}

If we know what version of Python is being used, we can specify the encoding as unicode or utf-8. Otherwise, if we need compatibility with both Python 2 & 3, we can use decode() to convert into the correct type.

For reference, I've included a comparison of .tostring() results between Python 2 and Python 3.

ElementTree.tostring(xml)
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />

ElementTree.tostring(xml, encoding='unicode')
# Python 3: <Person Name="John" />
# Python 2: LookupError: unknown encoding: unicode

ElementTree.tostring(xml, encoding='utf-8')
# Python 3: b'<Person Name="John" />'
# Python 2: <Person Name="John" />

ElementTree.tostring(xml).decode()
# Python 3: <Person Name="John" />
# Python 2: <Person Name="John" />

Thanks to Martijn Peters for pointing out that the str datatype changed between Python 2 and 3.

Why not use str()?

In most scenarios, using str() would be the "cannonical" way to convert an object to a string. Unfortunately, using this with Element returns the object's location in memory as a hexstring, rather than a string representation of the object's data.

from xml.etree import ElementTree

xml = ElementTree.Element("Person", Name="John")
print(str(xml))  # <Element 'Person' at 0x00497A80>

You can also just return string if you know that's the only thing the method will ever return. For example:

public string MyActionName() {
  return "Hi there!";
}

Latest update: You don't have to give any urls if you are testing it in development. You can leave the fields empty. Make sure your app is in development mode. If not turn off status from live.

No need to provide site url, app domains or valid redirect oauth uri.

Remove the text decoration for the anchor tag

Not an answer to the original question, but an example to the how-to-make-reusable and working custom renderers without breaking MVC :-)

// WRONG
public class DataWrapper {
   final Data data;
   final String description;
   public DataWrapper(Object data, String description) {
       this.data = data;
       this.description = description;
   }
   ....
   @Override
   public String toString() {
       return description;
   } 
}
// usage
myModel.add(new DataWrapper(data1, data1.getName());

It is wrong in a MVC environment, because it is mixing data and view: now the model doesn't contain the data but a wrapper which is introduced for view reasons. That's breaking separation of concerns and encapsulation (every class interacting with the model needs to be aware of the wrapped data).

The driving forces for breaking of rules were:

• keep functionality of the default KeySelectionManager (which is broken by a custom renderer)
• reuse of the wrapper class (can be applied to any data type)

As in Swing a custom renderer is the small coin designed to accomodate for custom visual representation, a default manager which can't cope is ... broken. Tweaking design just to accommodate for such a crappy default is the wrong way round, kind of upside-down. The correct is, to implement a coping manager.

While re-use is fine, doing so at the price of breaking the basic architecture is not a good bargin.

We have a problem in the presentation realm, let's solve it in the presentation realm with the elements designed to solve exactly that problem. As you might have guessed, SwingX already has such a solution :-)

In SwingX, the provider of a string representation is called StringValue, and all default renderers take such a StringValue to configure themselves:

StringValue sv = new StringValue() {
     @Override
     public String getString(Object value) {
        if (value instanceof Data) {
            return ((Data) value).getSomeProperty();
        }
        return TO_STRING.getString(value);
     }
};
DefaultListRenderer renderer = new DefaultListRenderer(sv);

As the defaultRenderer is-a StringValue (implemented to delegate to the given), a well-behaved implementation of KeySelectionManager now can delegate to the renderer to find the appropriate item:

public BetterKeySelectionManager implements KeySelectionManager {

     @Override
     public int selectionForKey(char ch, ComboBoxModel model) {

         ....
         if (getCellRenderer() instance of StringValue) {
              String text = ((StringValue) getCellRenderer()).getString(model.getElementAt(row));
              ....
         } 
     }

}

Outlined the approach because it is easily implementable even without using SwingX, simply define implement something similar and use it:

• some provider of a string representation
• a custom renderer which is configurable by that provider and guarantees to use it in configuring itself
• a well-behaved keySelectionManager with queries the renderer for its string represention

All except the string provider is reusable as-is (that is exactly one implemenation of the custom renderer and the keySelectionManager). There can be general implementations of the string provider, f.i. those formatting value or using bean properties via reflection. And all without breaking basic rules :-)

The function you're looking for is 'Insert'. It takes as its parameters the index you want to insert at, and an array of values to use for the new row values. Typical usage might include:

myDataGridView.Rows.Insert(4,new object[]{value1,value2,value3});

or something to that effect.

I know this is an old thread, but if you prefer case-insensitive searching:

SELECT * FROM INFORMATION_SCHEMA.TABLES 
WHERE Lower(TABLE_NAME) LIKE Lower('%%')

I'd just like to add to Jon's example. To get a reference to your own assembly, you can use:

Assembly myAssembly = Assembly.GetExecutingAssembly();

System.Reflection namespace.

If you want to examine an assembly that you have no reference to, you can use either of these:

Assembly assembly = Assembly.ReflectionOnlyLoad(fullAssemblyName);
Assembly assembly = Assembly.ReflectionOnlyLoadFrom(fileName);

If you intend to instantiate your type once you've found it:

Assembly assembly = Assembly.Load(fullAssemblyName);
Assembly assembly = Assembly.LoadFrom(fileName);

See the Assembly class documentation for more information.

Once you have the reference to the Assembly object, you can use assembly.GetTypes() like Jon already demonstrated.

the simple way is curl (and FASTER too)

<?php
$mylinks="http://site.com/page.html";
$handlerr = curl_init($mylinks);
curl_setopt($handlerr,  CURLOPT_RETURNTRANSFER, TRUE);
$resp = curl_exec($handlerr);
$ht = curl_getinfo($handlerr, CURLINFO_HTTP_CODE);


if ($ht == '404')
     { echo 'OK';}
else { echo 'NO';}

?>

On MySQL 5.7.x you need to switch to native password to be able to change it, like:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'test';

adjustResize = resize the page content

adjustPan = move page content without resizing page content

This is the real life scenario

Imagine this scenario

1. You have a global CSS file that sets visual aspects of your site globally.
2. You (or others) use inline styles on elements themselves which is usually very bad practice.

In this case you could set certain styles in your global CSS file as important, thus overriding inline styles set directly on elements.

Actual real world example?

This kind of scenario usually happens when you don't have total control over your HTML. Think of solutions in SharePoint for instance. You'd like your part to be globally defined (styled), but some inline styles you can't control are present. !important makes such situations easier to deal with.

Other real life scenarios would also include some badly written jQuery plugins that also use inline styles...

I suppose you got the idea by now and can come up with some others as well.

When do you decide to use !important?

I suggest you don't use !important unless you can't do it any other way. Whenever it's possible to avoid it, avoid it. Using lots of !important styles will make maintenance a bit harder, because you break the natural cascading in your stylesheets.

Try this:

select Activity, SUM(Incomes.Amount) as "Total Amount 2009", SUM(Incomes2008.Amount) 
as "Total Amount 2008" from
Activities, Incomes, Incomes2008
where Activities.UnitName = ?  AND
Incomes.ActivityId = Activities.ActivityID  AND
Incomes2008.ActivityId = Activities.ActivityID GROUP BY
Activity ORDER BY Activity;

Basically you have to JOIN Incomes2008 table with the output of your first query.

(This has been deprecated now you can use ImageBackground)

This is how I've done it. The main deal was getting rid of the static fixed sizes.

class ReactStrap extends React.Component {
  render() {
    return (
      <Image source={require('image!background')} style={styles.container}>
        ... Your Content ...
      </Image>
    );
  }
}

var styles = StyleSheet.create({
  container: {
    flex: 1,
    // remove width and height to override fixed static size
    width: null,
    height: null,
  }
};

I made on this way, and work properly to me:

if (listview1.Items.Count > 0)
        {
            for (int a = listview1.Items.Count -1; a > 0 ; a--)
            {
                listview1.Items.RemoveAt(a);
            }
                listview1.Refresh();

        }

Explaining: using "Clear()" erases only the items, do not removes then from object, using RemoveAt() to removing an item of beginning position just realocate the others [if u remove item[0], item[1] turns into [0] triggering a new internal event], so removing from the ending no affect de others position, its a Stack behavior, this way we can Stack over all items, reseting the object.

Most kinds of smart pointers handle disposing of the pointer-to object for you. It's very handy because you don't have to think about disposing of objects manually anymore.

The most commonly-used smart pointers are std::tr1::shared_ptr (or boost::shared_ptr), and, less commonly, std::auto_ptr. I recommend regular use of shared_ptr.

shared_ptr is very versatile and deals with a large variety of disposal scenarios, including cases where objects need to be "passed across DLL boundaries" (the common nightmare case if different libcs are used between your code and the DLLs).

Just in case you are able to utilize a scripting language to prepare your SQL queries, you could reuse field=value pairs by using SET instead of (a,b,c) VALUES(a,b,c).

An example with PHP:

$pairs = "a=$a,b=$b,c=$c";
$query = "INSERT INTO $table SET $pairs ON DUPLICATE KEY UPDATE $pairs";

Example table:

CREATE TABLE IF NOT EXISTS `tester` (
  `a` int(11) NOT NULL,
  `b` varchar(50) NOT NULL,
  `c` text NOT NULL,
  UNIQUE KEY `a` (`a`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

If whitespace becomes that important, it may be better to use preformatted text and the <pre> tag.

You can use python's built-in function sum

• sum will return the sum of all the values
• len to get list's length

code:

>>> list = [1,2,3,4]
>>> sum(list)
>>> 10
>>> len(list)
>>> 4
>>> avg = float(sum(list))/len(list)
>>> 2.5
>>>"""In pyton3 don't want to specify float"""
>>> 10 / 4
>>> 2.5 

Use float because when using python 2.x, because:

• int/int returns int value (i.e. 2)
• float/int returns float value (i.e. 2.5)

While in Python 3.x:

• int/int return float
• int//int return int

I used Selva's solution but had two kinds of issues:

• OnSeekbarChangeListener did not work properly
• Setting progress programmatically did not work properly.

I fixed these two issues. You can find the solution (within my own project package) at

https://github.com/jeisfeld/Augendiagnose/blob/master/AugendiagnoseIdea/augendiagnoseLib/src/main/java/de/jeisfeld/augendiagnoselib/components/VerticalSeekBar.java

Based on @EdChum's answer, you can try the following solution:

df[df.columns[pd.Series(df.columns).str.contains("foo")]]

This will be really helpful in case not all the columns you want to select start with foo. This method selects all the columns that contain the substring foo and it could be placed in at any point of a column's name.

In essence, I replaced .startswith() with .contains().

An alternative way using Vim(Vi compatible):

Delete duplicate, consecutive lines from a file:

vim -esu NONE +'g/\v^(.*)\n\1$/d' +wq

Delete duplicate, nonconsecutive and nonempty lines from a file:

vim -esu NONE +'g/\v^(.+)$\_.{-}^\1$/d' +wq

Pick one depends on the method you are looking for!?

I will go with ParentNode.children:

As it provides namedItem method that allows me directly to get one of the children elements without looping through all children or avoiding to use getElementById etc.

e.g.

ParentNode.children.namedItem('ChildElement-ID'); // JS
ref.current.children.namedItem('ChildElement-ID'); // React
this.$refs.ref.children.namedItem('ChildElement-ID'); // Vue

I will go with Node.childNodes:

As it provides forEach method when I work with window.IntersectionObserver e.g.

nodeList.forEach((node) => { observer.observe(node) })
// IE11 does not support forEach on nodeList, but easy to be polyfilled.

On Chrome 83

Node.childNodes provides entries, forEach, item, keys, length and values

ParentNode.children provides item, length and namedItem

Just use os.path.dirname(os.path.abspath(__file__)) and examine very carefully whether there is a real need for the case where exec is used. It could be a sign of troubled design if you are not able to use your script as a module.

Keep in mind Zen of Python #8, and if you believe there is a good argument for a use-case where it must work for exec, then please let us know some more details about the background of the problem.

As far as I can tell there is no upper limit in 2008.

In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg variable with

Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.

the code below fails with

REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.

However it appears these limitations have quietly been lifted. On 2008

DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681); 

SET @y = REPLICATE(@y,92681);

SELECT LEN(@y) 

Returns

8589767761

I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory

Running

select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid

Returned

internal_objects_alloc_page_co 
------------------------------ 
2144456    

so I presume this all just gets stored in LOB pages in tempdb with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681); statement. The initial variable assignment to @y and the LEN calculation did not increase this.

The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE method isn't supported for varchar(max) variables.

Addition

I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max) and nvarchar(max) + varchar(max). Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. again. The script for that is below (may take a long time to run).

DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647); 
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1)  /*4294967294, 4294967292*/


DECLARE @y2 NVARCHAR(MAX) = REPLICATE(CAST('X' AS NVARCHAR(MAX)),1073741823); 
SET @y2 = @y2 + @y2;
SELECT LEN(@y2), DATALENGTH(@y2)  /*2147483646, 4294967292*/


DECLARE @y3 NVARCHAR(MAX) = @y2 + @y1
SELECT LEN(@y3), DATALENGTH(@y3)   /*6442450940, 12884901880*/

/*This attempt fails*/
SELECT @y1 y1, @y2 y2, @y3 y3

If you are referring to the npm module sleep, it notes in the readme that sleep will block execution. So you are right - it isn't what you want. Instead you want to use setTimeout which is non-blocking. Here is an example:

setTimeout(function() {
  console.log('hello world!');
}, 5000);

For anyone looking to do this using es7 async/await, this example should help:

const snooze = ms => new Promise(resolve => setTimeout(resolve, ms));

const example = async () => {
  console.log('About to snooze without halting the event loop...');
  await snooze(1000);
  console.log('done!');
};

example();

Well, maybe an int does not posses the len attribute in Python like your error suggests?

Try:

len(str(numbers))

Only way I can think of is to concatenate the worksheet name with the cell reference, as follows:

Dim cell As Range
Dim cellAddress As String
Set cell = ThisWorkbook.Worksheets(1).Cells(1, 1)
cellAddress = cell.Parent.Name & "!" & cell.Address(External:=False)

EDIT:

Modify last line to :

cellAddress = "'" & cell.Parent.Name & "'!" & cell.Address(External:=False) 

if you want it to work even if there are spaces or other funny characters in the sheet name.

ListBox will try to expand in height that is available.. When you set the Height property of ListBox you get a scrollviewer that actually works...

If you wish your ListBox to accodate the height available, you might want to try to regulate the Height from your parent controls.. In a Grid for example, setting the Height to Auto in your RowDefinition might do the trick...

If you decided to write your hello.World class in Kotlin, another issue might be that you have to reference it as mainClassName = "hello.WorldKt".

src/main/java/hello/World.kt:

package hello
fun main(args: Array<String>) {
    ...
}
// class World {} // this line is not necessary

input(char_val, date9.);

You can consider to convert it to word format using input(char_val, worddate.)

None of the solutions above worked for me (Eclipse Juno with JDK 1.7_015). Java could only find the libraries when I moved them from project_folder/lib to project_folder.

In my case, I had several applications installed having the same domain name in the package name as follows.

com.mypackage.app1
com.mypackage.app2
com.mypackage.app3 
...

I had to uninstall all the apps having similar package names and reinstall them again in order to get rid of the problem.

To find all package names from the device I used the following.

adb shell pm list packages

Then I grabbed the packages that match my package name that I am looking for.

dumpsys | grep -A18 "Package \[com.mypackage\]"

Then uninstalled all the apps having that domain.

uninstall com.mypackage.app1
uninstall com.mypackage.app2
uninstall com.mypackage.app3
...

You can also uninstall the applications using the Settings app. Go to the Settings -> Apps -> Find the app -> Uninstall

Hope that helps someone having the same problem as me.

There is no way you can hidde the keyboard properly with js because its a OS problem, so one thing you can easy do to "hidde" the keyboard, is instead of using an input Element you can make any "non-input html element" a key listener element just by adding the [tabindex] attribute, and then you can easily listen the keydown and keyup events and store the "$event.target.value" in a variable to get the input.

Execute:

nc -v -z <git-repository> <port>

Your output should look like:

"Connection to <git-repository> <port> port [tcp/*] succeeded!"

If you get:

connect to <git-repository> <port> (tcp) failed: Connection timed out

You need to edit your ~/.ssh/config file. Add something like the following:

Host example.com
Port 1234

To remove all columns after the one you want, below code should work. It will remove at index 10 (remember Columns are 0 based), until the Column count is 10 or less.

DataTable dt;
int desiredSize = 10;

while (dt.Columns.Count > desiredSize)
{
   dt.Columns.RemoveAt(desiredSize);
}

This works because Integer::min resolves to an implementation of the Comparator<Integer> interface.

The method reference of Integer::min resolves to Integer.min(int a, int b), resolved to IntBinaryOperator, and presumably autoboxing occurs somewhere making it a BinaryOperator<Integer>.

And the min() resp max() methods of the Stream<Integer> ask the Comparator<Integer> interface to be implemented.
Now this resolves to the single method Integer compareTo(Integer o1, Integer o2). Which is of type BinaryOperator<Integer>.

And thus the magic has happened as both methods are a BinaryOperator<Integer>.

You need to use Arrow function ()=> ES6 feature to preserve this context within setTimeout.

// var that = this;                             // no need of this line
this.messageSuccess = true;

setTimeout(()=>{                           //<<<---using ()=> syntax
      this.messageSuccess = false;
 }, 3000);

Given $arrService = Get-Service -Name $ServiceName, $arrService.Status is a static property, corresponding to the value at the time of the call. Use $arrService.Refresh() when needed to renew the properties to current values.

MSDN ~ ServiceController.Refresh()

Refreshes property values by resetting the properties to their current values.

You can create functions in react components. It is actually regular ES6 class which inherits from React.Component. Just be careful and bind it to the correct context in onClick event:

export default class Archive extends React.Component { 

    saySomething(something) {
        console.log(something);
    }

    handleClick(e) {
        this.saySomething("element clicked");
    }

    componentDidMount() {
        this.saySomething("component did mount");
    }

    render() {
        return <button onClick={this.handleClick.bind(this)} value="Click me" />;
    }
}

OpenFileDialog fdlg = new OpenFileDialog();
fdlg.Title = "C# Corner Open File Dialog" ;
fdlg.InitialDirectory = @"c:\" ;
fdlg.Filter = "All files (*.*)|*.*|All files (*.*)|*.*" ;
fdlg.FilterIndex = 2 ;
fdlg.RestoreDirectory = true ;
if(fdlg.ShowDialog() == DialogResult.OK)
{
textBox1.Text = fdlg.FileName ;
}

In this code you can put your address in a text box.

Using grep on the results of ps is a bad idea in a script, since some proportion of the time it will also match the grep process you've just invoked. The command pgrep avoids this problem, so if you need to know the process ID, that's a better option. (Note that, of course, there may be many processes matched.)

However, in your example, you could just use the similar command pkill to kill all matching processes:

pkill ruby

Incidentally, you should be aware that using -9 is overkill (ho ho) in almost every case - there's some useful advice about that in the text of the "Useless Use of kill -9 form letter ":

No no no. Don't use kill -9.

It doesn't give the process a chance to cleanly:

1. shut down socket connections
2. clean up temp files
3. inform its children that it is going away
4. reset its terminal characteristics

and so on and so on and so on.

Generally, send 15, and wait a second or two, and if that doesn't work, send 2, and if that doesn't work, send 1. If that doesn't, REMOVE THE BINARY because the program is badly behaved!

Don't use kill -9. Don't bring out the combine harvester just to tidy up the flower pot.

AutoScroll is really the solution! You just have to set AutoScrollMargin to 0, 1000 or something like this, then use it to scroll down and add buttons and items there!

Use a resize sensor from the css-element-queries library:

It uses a event based approach and doesn't waste your cpu time. Works in all browsers incl. IE7+.

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

How I account for my site being behind an Amazon AWS Elastic Load Balancer (ELB):

public class GetPublicIp {

    /// <summary>
    /// account for possbility of ELB sheilding the public IP address
    /// </summary>
    /// <returns></returns>
    public static string Execute() {
        try {
            Console.WriteLine(string.Join("|", new List<object> {
                    HttpContext.Current.Request.UserHostAddress,
                    HttpContext.Current.Request.Headers["X-Forwarded-For"],
                    HttpContext.Current.Request.Headers["REMOTE_ADDR"]
                })
            );

            var ip = HttpContext.Current.Request.UserHostAddress;
            if (HttpContext.Current.Request.Headers["X-Forwarded-For"] != null) {
                ip = HttpContext.Current.Request.Headers["X-Forwarded-For"];
                Console.WriteLine(ip + "|X-Forwarded-For");
            }
            else if (HttpContext.Current.Request.Headers["REMOTE_ADDR"] != null) {
                ip = HttpContext.Current.Request.Headers["REMOTE_ADDR"];
                Console.WriteLine(ip + "|REMOTE_ADDR");
            }
            return ip;
        }
        catch (Exception ex) {
            Console.Error.WriteLine(ex.Message);
        }
        return null;
    }
}

I use the following function extensively. As pointed out above, using other methods can sometimes give inaccurate results due to used range updates, gaps in the data, or different columns having different row counts.

Example of use:

lastRow=FindRange("Sheet1","A1:A1000")

would return the last occupied row number of the entire range. You can specify any range you want from single columns to random rows, eg FindRange("Sheet1","A100:A150")

Public Function FindRange(inSheet As String, inRange As String) As Long
    Set fr = ThisWorkbook.Sheets(inSheet).Range(inRange).find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious)
    If Not fr Is Nothing Then FindRange = fr.row Else FindRange = 0
End Function

Another way to do this is (using Apache Commons FileUtils) -

private void printEmptyFileName(final File file) throws IOException {
    if (FileUtils.readFileToString(file).trim().isEmpty()) {
        System.out.println("File is empty: " + file.getName());
    }        
}

Very simple by using the string format

on .ToSTring("") :

• if you use "hh" ->> The hour, using a 12-hour clock from 01 to 12.

• if you use "HH" ->> The hour, using a 24-hour clock from 00 to 23.

• if you add "tt" ->> The Am/Pm designator.

exemple converting from 23:12 to 11:12 Pm :

DateTime d = new DateTime(1, 1, 1, 23, 12, 0);
var res = d.ToString("hh:mm tt");   // this show  11:12 Pm
var res2 = d.ToString("HH:mm");  // this show  23:12

Console.WriteLine(res);
Console.WriteLine(res2);

Console.Read();

wait a second that is not all you need to care about something else is the system Culture because the same code executed on windows with other langage especialy with difrent culture langage will generate difrent result with the same code

exemple of windows set to Arabic langage culture will show like that :

// 23:12 ?

? means Evening (first leter of ????) .

in another system culture depend on what is set on the windows regional and language option, it will show // 23:12 du.

you can change between different format on windows control panel under windows regional and language -> current format (combobox) and change... apply it do a rebuild (execute) of your app and watch what iam talking about.

so who can I force showing Am and Pm Words in English event if the culture of the current system isn't set to English ?

easy just by adding two lines : ->

the first step add using System.Globalization; on top of your code

and modifing the Previous code to be like this :

DateTime d = new DateTime(1, 1, 1, 23, 12, 0);
var res = d.ToString("HH:mm tt", CultureInfo.InvariantCulture); // this show  11:12 Pm

InvariantCulture => using default English Format.

another question I want to have the pm to be in Arabic or specific language, even if I use windows set to English (or other language) regional format?

Soution for Arabic Exemple :

DateTime d = new DateTime(1, 1, 1, 23, 12, 0);
var res = d.ToString("HH:mm tt", CultureInfo.CreateSpecificCulture("ar-AE")); 

this will show // 23:12 ?

event if my system is set to an English region format. you can change "ar-AE" if you want to another language format. there is a list of each language and its format.

exemples : ar ar-SA Arabic ar-BH ar-BH Arabic (Bahrain) ar-DZ ar-DZ Arabic (Algeria) ar-EG ar-EG Arabic (Egypt)

For python3 on ubuntu, this worked for me:

$sudo apt-get update
$sudo apt-get install libpq-dev
$sudo pip3 install psycopg2-binary

ZShape is not static so it requires an instance of the outer class.

The simplest solution is to make ZShape and any nested class static if you can.

I would also make any fields final or static final that you can as well.

You're making an HTTP POST, but trying to pass parameters with the GET query string syntax. In a POST, the data are passed as named parameters and do not use the param=value&foo=bar syntax. Using jQuery's ajax method lets you create a javascript object with the named parameters, like so:

$.ajax({
  url: '/Home/SaveChart',
  type: 'POST',
  async: false,
  dataType: 'text',
  processData: false,    
  data: { 
      input: JSON.stringify(IVRInstant.data), 
      name: $("#wrkname").val()
  },
  success: function (data) { }
});

I recommend more understanding way using extension method:

public static class KeyValuePairExtensions
{
    public static bool IsNull<T, TU>(this KeyValuePair<T, TU> pair)
    {
        return pair.Equals(new KeyValuePair<T, TU>());
    }
}

And then just use:

var countries = new Dictionary<string, string>
{
    {"cz", "prague"},
    {"de", "berlin"}
};

var country = countries.FirstOrDefault(x => x.Key == "en");

if(country.IsNull()){

}

I've written a few methods for convert by Gson library and java 1.8 .
thay are daynamic model for convert.

string to object

object to string

List to string

string to List

HashMap to String

String to JsonObj

//saeedmpt 
public static String convertMapToString(Map<String, String> data) {
    //convert Map  to String
    return new GsonBuilder().setPrettyPrinting().create().toJson(data);
}
public static <T> List<T> convertStringToList(String strListObj) {
    //convert string json to object List
    return new Gson().fromJson(strListObj, new TypeToken<List<Object>>() {
    }.getType());
}
public static <T> T convertStringToObj(String strObj, Class<T> classOfT) {
    //convert string json to object
    return new Gson().fromJson(strObj, (Type) classOfT);
}

public static JsonObject convertStringToJsonObj(String strObj) {
    //convert string json to object
    return new Gson().fromJson(strObj, JsonObject.class);
}

public static <T> String convertListObjToString(List<T> listObj) {
    //convert object list to string json for
    return new Gson().toJson(listObj, new TypeToken<List<T>>() {
    }.getType());
}

public static String convertObjToString(Object clsObj) {
    //convert object  to string json
    String jsonSender = new Gson().toJson(clsObj, new TypeToken<Object>() {
    }.getType());
    return jsonSender;
}

count(*) is an aggregate function. Aggregate functions need to be grouped for a meaningful results. You can read: count columns group by

I found the same issue and tried everything. I have two different apps, one in objective-C and one in swift - both have the same problem. The error message comes in the debugger and the screen goes black after the first photo. This only happens in iOS >= 8.0, obviously it is a bug.

I found a difficult workaround. Shut off the camera controls with imagePicker.showsCameraControls = false and create your own overlayView that has the missing buttons. There are various tutorials around how to do this. The strange error message stays, but at least the screen doesn't go black and you have a working app.

Plus you need to add this android:layout_width="0dp" for children views [Button views] of LinerLayout

About the removal of componentWillReceiveProps: you should be able to handle its uses with a combination of getDerivedStateFromProps and componentDidUpdate, see the React blog post for example migrations. And yes, the object returned by getDerivedStateFromProps updates the state similarly to an object passed to setState.

In case you really need the old value of a prop, you can always cache it in your state with something like this:

state = {
  cachedSomeProp: null
  // ... rest of initial state
};

static getDerivedStateFromProps(nextProps, prevState) {
  // do things with nextProps.someProp and prevState.cachedSomeProp
  return {
    cachedSomeProp: nextProps.someProp,
    // ... other derived state properties
  };
}

Anything that doesn't affect the state can be put in componentDidUpdate, and there's even a getSnapshotBeforeUpdate for very low-level stuff.

UPDATE: To get a feel for the new (and old) lifecycle methods, the react-lifecycle-visualizer package may be helpful.

ReLU(x) also is equal to (x+abs(x))/2

It looks OK apart from the space in your ID attribute, which is not valid, and the fact that you're replacing the value of your input before checking the selection.

function textbox()_x000D_
{_x000D_
        var ctl = document.getElementById('Javascript_example');_x000D_
        var startPos = ctl.selectionStart;_x000D_
        var endPos = ctl.selectionEnd;_x000D_
        alert(startPos + ", " + endPos);_x000D_
}

<input id="Javascript_example" name="one" type="text" value="Javascript example" onclick="textbox()">

Also, if you're supporting IE <= 8 you need to be aware that those browsers do not support selectionStart and selectionEnd.

I think ForkJoinPool and related enhancement to Executor Framework is an important addition in Java 7.

Use any of the following:

String str = String.valueOf('c');
String str = Character.toString('c');
String str = 'c' + "";

There are a few ways to convert String to long:

1)

long l = Long.parseLong("200"); 

String numberAsString = "1234";
long number = Long.valueOf(numberAsString).longValue();

String numberAsString = "1234";
Long longObject = new Long(numberAsString);
long number = longObject.longValue();

We can shorten to:

String numberAsString = "1234";
long number = new Long(numberAsString).longValue();

Or just

long number = new Long("1234").longValue();

4. Using Decimal format:

String numberAsString = "1234";
DecimalFormat decimalFormat = new DecimalFormat("#");
try {
    long number = decimalFormat.parse(numberAsString).longValue();
    System.out.println("The number is: " + number);
} catch (ParseException e) {
    System.out.println(numberAsString + " is not a valid number.");
}

Pass the array to a method that sorts it with Arrays.sort() so it only sorts the array the method is using then sets min to array[0] and max to array[array.length-1].

Starting simple, with no HTML:

foreach($database as $file) {
    echo $file['filename'] . ' at ' . $file['filepath'];
}

And you can otherwise manipulate the fields in the foreach.

This may also happen if your JSON file is not just 1 JSON record. A JSON record looks like this:

[{"some data": value, "next key": "another value"}]

It opens and closes with a bracket [ ], within the brackets are the braces { }. There can be many pairs of braces, but it all ends with a close bracket ]. If your json file contains more than one of those:

[{"some data": value, "next key": "another value"}]
[{"2nd record data": value, "2nd record key": "another value"}]

then loads() will fail.

I verified this with my own file that was failing.

import json

guestFile = open("1_guests.json",'r')
guestData = guestFile.read()
guestFile.close()
gdfJson = json.loads(guestData)

This works because 1_guests.json has one record []. The original file I was using all_guests.json had 6 records separated by newline. I deleted 5 records, (which I already checked to be bookended by brackets) and saved the file under a new name. Then the loads statement worked.

Error was

   raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 2 column 1 - line 10 column 1 (char 261900 - 6964758)

PS. I use the word record, but that's not the official name. Also, if your file has newline characters like mine, you can loop through it to loads() one record at a time into a json variable.

If you are trying to find a View from your Fragment then try doing it like this:

int w = ((EditText)getActivity().findViewById(R.id.editText1)).getLayoutParams().width;

I just finished a .net library with a few useful queries that return strongly typed C# objects for code gen/ t4 templates.

Foreign Key Metadata

With this method you evoke the flush process. This process synchronizes the state of your database with state of your session by detecting state changes and executing the respective SQL statements.

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

public class Sandbox {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Boolean b = true;
        boolean z = false;
        echo (b);
        echo (z);
        echo ("Value of b= " + b +"\nValue of z= " + z);
    }

    public static void echo(Object obj){
        System.out.println(obj);
    } 

}

Result
--------------
true
false
Value of b= true
Value of z= false
--------------

To find out URI:

current_uri = request.env['PATH_INFO']
# If you are browsing http://example.com/my/test/path, 
# then above line will yield current_uri as "/my/test/path"

To find out the route i.e. controller, action and params:

path = ActionController::Routing::Routes.recognize_path "/your/path/here/"

# ...or newer Rails versions:
#
path = Rails.application.routes.recognize_path('/your/path/here')

controller = path[:controller]
action = path[:action]
# You will most certainly know that params are available in 'params' hash

Your code works, but the fadeIn doesn't, because it's already visible. I think the effect you want to achieve is: fadeOut → load → fadeIn:

var auto_refresh = setInterval(function () {
    $('.View').fadeOut('slow', function() {
        $(this).load('/echo/json/', function() {
            $(this).fadeIn('slow');
        });
    });
}, 15000); // refresh every 15000 milliseconds

Try it here: http://jsfiddle.net/kelunik/3qfNn/1/

Additional notice: As Khanh TO mentioned, you may need to get rid of the browser's internal cache. You can do so using $.ajax and $.ajaxSetup ({ cache: false }); or the random-hack, he mentioned.

There's an approach using the Microsoft Templating approach that's currently under proposal for inclusion into jQuery core. There's more power in using the templating so for the simplest scenario it may not be the best option. For more details see Scott Gu's post outlining the features.

First include the templating js file, available from github.

<script src="Scripts/jquery.tmpl.js" type="text/javascript" />

Next set-up a template

<script id="templateOptionItem" type="text/html">
    <option value=\'{{= Value}}\'>{{= Text}}</option>
</script>

Then with your data call the .render() method

var someData = [
    { Text: "one", Value: "1" },
    { Text: "two", Value: "2" },
    { Text: "three", Value: "3"}];

$("#templateOptionItem").render(someData).appendTo("#mySelect");

I've blogged this approach in more detail.

IP Address

You can get network interfaces with NetworkInterface.getNetworkInterfaces(), then the IP addresses off the NetworkInterface objects returned with .getInetAddresses(), then the string representation of those addresses with .getHostAddress().

Port

If you make a @Configuration class which implements ApplicationListener<EmbeddedServletContainerInitializedEvent>, you can override onApplicationEvent to get the port number once it's set.

@Override
public void onApplicationEvent(EmbeddedServletContainerInitializedEvent event) {
    int port = event.getEmbeddedServletContainer().getPort();
}

In this case, using WebView#loadDataWithBaseUrl() is better than WebView#loadUrl()!

webView.loadDataWithBaseURL(url, 
        data,
        "text/html",
        "utf-8",
        null);

url: url/path String pointing to the directory all your JavaScript files and html links have their origin. If null, it's about:blank. data: String containing your hmtl file, read with BufferedReader for example

More info: WebView.loadDataWithBaseURL(java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String)

Similar to @Aaron Digulla's suggestion except that I would suggest a graphics design tool, select the base color, in your case the background color, then adjust the Hue, Saturation and Value. Using this you can create color swatches very easily. Paint.Net is free and I use it all the time for this and also the pay-for-tools will also do this.

You can use Excel's Index function:

=INDEX(Age, 5)

None of above worked for me. Using Android Studio 3.5 Beta 4. I even selected "do not save, forget passwords after restart" in file>settings>appearance & behavior>System settings>password

So What I did.

VCS>git>remotes

• remove the repo and add again.
• will ask for credentials.
• then try git fetch in terminal.
• Will prompt for password.
• Issue fixed. :D

Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)

sub myhandler(eventsource)
  process(eventsource.value)
end sub

for each cell
  cell.setEventHandler(myHandler)

But i dont know the syntax for achieving this in VB/VBA, or if is even possible.

Since I don't find a simple answer just adding more this will be JSP page. save this content to a jsp file once you run you can see the values of the selected displayed.

Update: save the file as test.jsp and run it on any web/app server

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<%@ page import="java.lang.*" %>
<%@ page import="java.io.*" %>
<% String[] a = request.getParameterValues("multiple");
if(a!=null)
{
for(int i=0;i<a.length;i++){
//out.println(Integer.parseInt(a[i])); //If integer
out.println(a[i]);
}}
%>
<html>
<body>
<form action="test.jsp" method="get">
<select name="multiple" multiple="multiple"><option value="1">1</option><option value="2">2</option><option value="3">3</option></select>
<input type="submit">
</form>
</body>
</html>

Instead of using a temporary file, you can avoid creating a subshell around the while loop by using process substitution.

while ...
do
   ...
done < <(grep ...)

By the way, you should be able to transform all that grep, grep, awk, awk, awk into a single awk.

Starting with Bash 4.2, there is a lastpipe option that

runs the last command of a pipeline in the current shell context. The lastpipe option has no effect if job control is enabled.

bash -c 'echo foo | while read -r s; do c=3; done; echo "$c"'

bash -c 'shopt -s lastpipe; echo foo | while read -r s; do c=3; done; echo "$c"'
3

If the file contains only parameter assignments, you can use the following loop in place of sourcing it:

# Instead of source file.txt
while IFS="=" read name value; do
    declare "$name=$value"
done < file.txt

This saves you having to quote anything in the file, and is also more secure, as you don't risk executing arbitrary code from file.txt.

Another solution, using jQuery:

$(document).ready(function() {
  $("input").keypress(function(e) {
    if (e.which == 13) {
      $('#submit').click();
      return false;
    }

    return true;
  });
});

This should work on the following forms, making "Update" the default action:

<form name="f" method="post" action="/action">
  <input type="text" name="text1" />
  <input type="submit" name="button2" value="Delete" />
  <input type="submit" name="button1" id="submit" value="Update" />
</form>

As well as:

<form name="f" method="post" action="/action">
  <input type="text" name="text1" />
  <button type="submit" name="button2">Delete</button>
  <button type="submit" name="button1" id="submit">Update</button>
</form>

This traps the Enter key only when an input field on the form has focus.

I had the problem with it being in a data set being pushed across the wire (webservice to client) that it would automatically change because the DataColumn's DateType field was set to local. Make sure you check what the DateType is if your pushing DataSets across.

If you don't want it to change, set it to Unspecified

The VBScript Messagebox is fairly limited as to the labels you can apply to the buttons, your choices are pretty much limited to:

• OK
• Cancel
• Retry
• Abort
• Ignore
• Yes
• No

So you are going to have to build your own form if you want "ON"/"OFF"

Better yet, why not rephrase the prompt in the box so one of the above options works.

For example:

Do you want the light on? 
[Yes] [No]

And for God's sake don't do one of these UI monstrosities!

Switch setting? (Click "yes" for ON and "No" for Off)
[Yes] [No]

Update Java 8 usage of default keyword: As many others have noted The default visibility (no keyword)

the field will be accessible from inside the same package to which the class belongs.

Not to be confused with the new Java 8 feature (Default Methods) that allows an interface to provide an implementation when its labeled with the default keyword.

See: Access modifiers

You may use CString, CStringA, CStringW to do automatic conversions and convert between these types. Further, you may also use CStrBuf, CStrBufA, CStrBufW to get RAII pattern modifiable strings

If you can't use box-sizing (e.g. when you convert HTML to PDF using iText). Try this:

CSS

.input-wrapper { border: 1px solid #ccc; padding: 0 5px; min-height: 20px; } 
.input-wrapper input[type=text] { border: none; height: 20px; width: 100%; padding: 0; margin: 0; }

HTML

<div class="input-wrapper">
     <input type="text" value="" name="city"/>
</div>

If you add:

jquery.form.min.js

You can simply do this:

<script>
$('#myform').ajaxForm(function(response) {
  alert(response);
});

// this will register the AJAX for <form id="myform" action="some_url">
// and when you submit the form using <button type="submit"> or $('myform').submit(), then it will send your request and alert response
</script>

NOTE:

You could use simple $('FORM').serialize() as suggested in post above, but that will not work for FILE INPUTS... ajaxForm() will.

My original answer dealt with the BottomNavigationView, but now there is a BottomAppBar. I added a section at the top for that with an implementation link.

Bottom App Bar

The BottomAppBar supports a Floating Action Button.

Image from here. See the documentation and this tutorial for help setting up the BottomAppBar.

Bottom Navigation View

The following full example shows how to make a Bottom Navigation View similar to the image in the question. See also Bottom Navigation in the documentation.

Add the design support library

Add this line to your app's build.grade file next to the other support library things.

implementation 'com.android.support:design:28.0.0'

Replace the version number with whatever is current.

Create the Activity layout

The only special thing we have added to the layout is the BottomNavigationView. To change the color of the icon and text when it is clicked, you can use a selector instead of specifying the color directly. This is omitted for simplicity here.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    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">

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        app:menu="@menu/bottom_nav_menu"
        app:itemBackground="@color/colorPrimary"
        app:itemIconTint="@android:color/white"
        app:itemTextColor="@android:color/white" />

</RelativeLayout>

Notice that we used layout_alignParentBottom to actually put it at the bottom.

Define the menu items

The xml above for Bottom Navigation View referred to bottom_nav_menu. This is what defines each item in our view. We will make it now. All you have to do is add a menu resource just like you would for an Action Bar or Toolbar.

bottom_nav_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/action_recents"
        android:enabled="true"
        android:icon="@drawable/ic_action_recents"
        android:title="Recents"
        app:showAsAction="ifRoom" />

    <item
        android:id="@+id/action_favorites"
        android:enabled="true"
        android:icon="@drawable/ic_action_favorites"
        android:title="Favorites"
        app:showAsAction="ifRoom" />

    <item
        android:id="@+id/action_nearby"
        android:enabled="true"
        android:icon="@drawable/ic_action_nearby"
        android:title="Nearby"
        app:showAsAction="ifRoom" />
</menu>

You will need to add the appropriate icons to your project. This is not very difficult if you go to File > New > Image Asset and choose Action Bar and Tab Icons as the Icon Type.

Add an item selected listener

There is nothing special happening here. We just add a listener to the Bottom Navigation Bar in our Activity's onCreate method.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation);
        bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {

I have just found the builtin imghdr module. From python documentation:

The imghdr module determines the type of image contained in a file or byte stream.

This is how it works:

>>> import imghdr
>>> imghdr.what('/tmp/bass')
'gif'

Using a module is much better than reimplementing similar functionality

To expand on Solomon Rutzky's answer, if you are looking for a piece of data that shows up in a range (i.e. more than once but less than 5x), you can use

having count(*) > 1 and count(*) < 5

And you can use whatever qualifiers you desire in there - they don't have to match, it's all just included in the 'having' statement. https://webcheatsheet.com/sql/interactive_sql_tutorial/sql_having.php

Map<String, Integer> map = new HashMap<>();
String key = "a random key";
int count = map.getOrDefault(key, 0); // ensure count will be one of 0,1,2,3,...
map.put(key, count + 1);

And that's how you increment a value with simple code.

Benefit:

• No need to add a new class or use another concept of mutable int
• Not relying on any library
• Easy to understand what's going on exactly (Not too much abstraction)

Downside:

• The hash map will be searched twice for get() and put(). So it will not be the most performant code.

Theoretically, once you call get(), you already know where to put(), so you should not have to search again. But searching in hash map usually takes a very minimal time that you can kind of ignore this performance issue.

But if you are very serious about the issue, you are a perfectionist, another way is to use merge method, this is (probably) more efficient than the previous code snippet as you will be (theoretically) searching the map only once: (though this code is not obvious from first sight, it's short and performant)

map.merge(key, 1, (a,b) -> a+b);

Suggestion: you should care about code readability more than little performance gain in most of the time. If the first code snippet is easier for you to understand then use it. But if you are able to understand the 2nd one fine then you can also go for it!

This is simple to do with Seaborn (pip install seaborn) as a oneliner

sns.scatterplot(x_vars="one", y_vars="two", data=df, hue="key1") :

import seaborn as sns
import pandas as pd
import numpy as np
np.random.seed(1974)

df = pd.DataFrame(
    np.random.normal(10, 1, 30).reshape(10, 3),
    index=pd.date_range('2010-01-01', freq='M', periods=10),
    columns=('one', 'two', 'three'))
df['key1'] = (4, 4, 4, 6, 6, 6, 8, 8, 8, 8)

sns.scatterplot(x="one", y="two", data=df, hue="key1")

Here is the dataframe for reference:

Since you have three variable columns in your data, you may want to plot all pairwise dimensions with:

sns.pairplot(vars=["one","two","three"], data=df, hue="key1")

https://rasbt.github.io/mlxtend/user_guide/plotting/category_scatter/ is another option.

Big O

f(x) = O(g(x)) when x goes to a (for example, a = +8) means that there is a function k such that:

1. f(x) = k(x)g(x)

2. k is bounded in some neighborhood of a (if a = +8, this means that there are numbers N and M such that for every x > N, |k(x)| < M).

In other words, in plain English: f(x) = O(g(x)), x ? a, means that in a neighborhood of a, f decomposes into the product of g and some bounded function.

Small o

By the way, here is for comparison the definition of small o.

f(x) = o(g(x)) when x goes to a means that there is a function k such that:

1. f(x) = k(x)g(x)

2. k(x) goes to 0 when x goes to a.

Examples

• sin x = O(x) when x ? 0.

• sin x = O(1) when x ? +8,

• x² + x = O(x) when x ? 0,

• x² + x = O(x²) when x ? +8,

• ln(x) = o(x) = O(x) when x ? +8.

Attention! The notation with the equal sign "=" uses a "fake equality": it is true that o(g(x)) = O(g(x)), but false that O(g(x)) = o(g(x)). Similarly, it is ok to write "ln(x) = o(x) when x ? +8", but the formula "o(x) = ln(x)" would make no sense.

More examples

• O(1) = O(n) = O(n²) when n ? +8 (but not the other way around, the equality is "fake"),

• O(n) + O(n²) = O(n²) when n ? +8

• O(O(n²)) = O(n²) when n ? +8

• O(n²)O(n³) = O(n⁵) when n ? +8

Here is the Wikipedia article: https://en.wikipedia.org/wiki/Big_O_notation

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

There is an instrumenting (function-accurate) profiler for MS VC 7.1 and higher called MicroProfiler. You can get it here (x64) or here (x86). It doesn't require any modifications or additions to your code and is able of displaying function statistics with callers and callees in real-time without the need of closing application/stopping the profiling process.

It integrates with VisualStudio, so you can easily enable/disable profiling for a project. It is also possible to install it on the clean machine, it only needs the symbol information be located along with the executable being profiled.

This tool is useful when statistical approximation from sampling profilers like Very Sleepy isn't sufficient.

Rough comparison shows, that it beats AQTime (when it is invoked in instrumenting, function-level run). The following program (full optimization, inlining disabled) runs three times faster with micro-profiler displaying results in real-time, than with AQTime simply collecting stats:

void f()
{
    srand(time(0));

    vector<double> v(300000);

    generate_n(v.begin(), v.size(), &random);
    sort(v.begin(), v.end());
    sort(v.rbegin(), v.rend());
    sort(v.begin(), v.end());
    sort(v.rbegin(), v.rend());
}

Here is simple example of how you can do this.

Just replace the image file and you are done.

Working DEMO

Ok guys it can be done easy in photoshop.

Open png photo and then check image -> mode value(i had indexed color). Go image -> mode and check rgb color. Now change your color EASY.

On Windows I use this code:

void * G_pPointer = NULL;
const char * G_szPointerName = NULL;
void CheckPointerIternal()
{
    char cTest = *((char *)G_pPointer);
}
bool CheckPointerIternalExt()
{
    bool bRet = false;

    __try
    {
        CheckPointerIternal();
        bRet = true;
    }
    __except (EXCEPTION_EXECUTE_HANDLER)
    {
    }

    return  bRet;
}
void CheckPointer(void * A_pPointer, const char * A_szPointerName)
{
    G_pPointer = A_pPointer;
    G_szPointerName = A_szPointerName;
    if (!CheckPointerIternalExt())
        throw std::runtime_error("Invalid pointer " + std::string(G_szPointerName) + "!");
}

Usage:

unsigned long * pTest = (unsigned long *) 0x12345;
CheckPointer(pTest, "pTest"); //throws exception

EDIT: You should use the DOMParser API as Wladimir suggests, I edited my previous answer since the function posted introduced a security vulnerability.

The following snippet is the old answer's code with a small modification: using a textarea instead of a div reduces the XSS vulnerability, but it is still problematic in IE9 and Firefox.

function htmlDecode(input){
  var e = document.createElement('textarea');
  e.innerHTML = input;
  // handle case of empty input
  return e.childNodes.length === 0 ? "" : e.childNodes[0].nodeValue;
}

htmlDecode("<img src='myimage.jpg'>"); 
// returns "<img src='myimage.jpg'>"

Basically I create a DOM element programmatically, assign the encoded HTML to its innerHTML and retrieve the nodeValue from the text node created on the innerHTML insertion. Since it just creates an element but never adds it, no site HTML is modified.

It will work cross-browser (including older browsers) and accept all the HTML Character Entities.

EDIT: The old version of this code did not work on IE with blank inputs, as evidenced here on jsFiddle (view in IE). The version above works with all inputs.

UPDATE: appears this doesn't work with large string, and it also introduces a security vulnerability, see comments.

I would propose simply:

def get_digest(file_path):
    h = hashlib.sha256()

    with open(file_path, 'rb') as file:
        while True:
            # Reading is buffered, so we can read smaller chunks.
            chunk = file.read(h.block_size)
            if not chunk:
                break
            h.update(chunk)

    return h.hexdigest()

All other answers here seem to complicate too much. Python is already buffering when reading (in ideal manner, or you configure that buffering if you have more information about underlying storage) and so it is better to read in chunks the hash function finds ideal which makes it faster or at lest less CPU intensive to compute the hash function. So instead of disabling buffering and trying to emulate it yourself, you use Python buffering and control what you should be controlling: what the consumer of your data finds ideal, hash block size.

My understanding of the asker's question is such that:

How does this magic work:

(function(){}) ('input')   // Used in his example

I may be wrong. However, the usual practice that people are familiar with is:

(function(){}('input') )

The reason is such that JavaScript parentheses AKA (), can't contain statements and when the parser encounters the function keyword, it knows to parse it as a function expression and not a function declaration.

I did a little experiment to see which of these methods

• string.startswith('hello')
• string.rfind('hello') == 0
• string.rpartition('hello')[0] == ''
• string.rindex('hello') == 0

are most efficient to return whether a certain string begins with another string.

Here is the result of one of the many test runs I've made, where each list is ordered to show the least time it took (in seconds) to parse 5 million of each of the above expressions during each iteration of the while loop I used:

['startswith: 1.37', 'rpartition: 1.38', 'rfind: 1.62', 'rindex: 1.62']

['startswith: 1.28', 'rpartition: 1.43', 'rfind: 1.59', 'rindex: 1.66']

I believe that it is pretty obvious from the start that the startswith method would come out the most efficient, as returning whether a string begins with the specified string is its main purpose.

What surprises me is that the seemingly impractical string.rpartition('hello')[0] == '' method always finds a way to be listed first, before the string.startswith('hello') method, every now and then. The results show that using str.partition to determine if a string starts with another string is more efficient then using both rfind and rindex.

Another thing I've noticed is that string.rindex('hello') == 0 and string.rindex('hello') == 0 have a good battle going on, each rising from fourth to third place, and dropping from third to fourth place, which makes sense, as their main purposes are the same.

Here is the code:

from time import perf_counter

string = 'hello world'
places = dict()

while True:
    start = perf_counter()
    for _ in range(5000000):
        string.startswith('hello')
    end = perf_counter()
    places['startswith'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rfind('hello') == 0
    end = perf_counter()
    places['rfind'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rpartition('hello')[0] == ''
    end = perf_counter()
    places['rpartition'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rindex('hello') == 0
    end = perf_counter()
    places['rindex'] = round(end - start, 2)
    
    print([f'{b}: {str(a).ljust(4, "4")}' for a, b in sorted(i[::-1] for i in places.items())])

1) You can use the !important rule, like this:

.selected
{
  background-color:red !important;
}

See http://www.w3.org/TR/CSS2/cascade.html#important-rules for more info.

2) In your example you can also get the red background by using ul.nav li.selected instead of just .selected. This makes the selector more specific.

See http://www.w3.org/TR/CSS2/cascade.html#specificity for more info.

I see a lot of positive feedback to responses I don't find accurate/complete at all.

There are two things to have in mind:

• Remote repository
• Local copy of the repository

If you haven't cloned your repo in your machine yet, you just need to rename the Github repository and then proceed to clone the repo so you can have a local copy. In order to rename the Github repo, you just need to:

1. Go to the repository site (i.e https://github.com/userX/repositoryZ).
2. In the navigation bar, you will see a tab named "Settings". Click on it.
3. Just edit the current repository name with the desired one and press "Rename".
4. Clone the repository as usual (i.e git clone https://github.com/userX/repositoryU).

If you already have a local copy of the project, apart from following the steps above, you need to make sure your local repository (root folder) is renamed properly and it's pointing to the right remote url :) link. In order to achieve that, do the following:

1. You might want to use the new given name for your repo. To do so, rename the local folder either by using the OS GUI(Finder, Windows Explorer, etc.) or console:

mv -R current-repo-name new-repo-name

2. Change the remote url. From the root of the folder, use the following:

$ git remote set-url origin https://github.com/userX/repositoryU

or

$ git remote set-url origin [email protected]:userX/repositoryU.git

The second step is not mandatory, though. Github announced a while ago that they would redirect all requests from previous repository urls to the assigned ones. That means you don't need to use $ git remote set-url ..., but they still encourage you to do so to avoid confusion.

Hope it helped. If you have any questions or the post is not clear enough, let me know.

data d is in row 0 and column 3 for value d :

DataTable table;
String d = (String)table.Rows[0][3];

Yes.

<head>
<script type='javascript'>
var x = 0;
</script>
</head>
<body>
  <input type='button' onclick='x++;'/>
</body>

[Psuedo code, god I hope this is right.]

Another option is to transform your data so that the effect of outliers is mitigated. You can do this by winsorizing your data.

import pandas as pd
from scipy.stats import mstats
%matplotlib inline

test_data = pd.Series(range(30))
test_data.plot()

# Truncate values to the 5th and 95th percentiles
transformed_test_data = pd.Series(mstats.winsorize(test_data, limits=[0.05, 0.05])) 
transformed_test_data.plot()

A "slug" is a way of generating a valid URL, generally using data already obtained. For instance, a slug uses the title of an article to generate a URL. I advise to generate the slug by means of a function, given the title (or another piece of data), rather than setting it manually.

An example:

<title> The 46 Year Old Virgin </title>
<content> A silly comedy movie </content>
<slug> the-46-year-old-virgin </slug>

Now let's pretend that we have a Django model such as:

class Article(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField(max_length=1000)
    slug = models.SlugField(max_length=40)

How would you reference this object with a URL and with a meaningful name? You could for instance use Article.id so the URL would look like this:

www.example.com/article/23

Or, you might want to reference the title like this:

www.example.com/article/The 46 Year Old Virgin

Since spaces aren't valid in URLs, they must be replaced by %20, which results in:

www.example.com/article/The%2046%20Year%20Old%20Virgin

Both attempts are not resulting in very meaningful, easy-to-read URL. This is better:

www.example.com/article/the-46-year-old-virgin

In this example, the-46-year-old-virgin is a slug: it is created from the title by down-casing all letters, and replacing spaces by hyphens -.

Also see the URL of this very web page for another example.

You can do this with jquery just visit http://jquery.com/ to get the link then do something like this

<a id="show_image">Show Image</a>
<img id="my_images" style="display:none" src="http://myimages.com/img.png">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $('#show_image').on("click", function(){
         $('#my_images').show('slow');
      });
   });
</script>

or if you would like the link to turn the image on and off do this

<a id="show_image">Show Image</a>
<img id="my_images" style="display:none;" src="http://myimages.com/img.png">

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $('#show_image').on("click", function(){
         $('#my_images').toggle();
      });
   });
</script>

You don't need 2 style attributes - just use one:

<img src="http://img705.imageshack.us/img705/119/original120x75.png" 
                                     style="height:100px;width:100px;" alt="25"/>

Consider, however, using a CSS class instead:

CSS:

.100pxSquare
{
  width: 100px;
  height: 100px;
}

HTML:

<img src="http://img705.imageshack.us/img705/119/original120x75.png" 
                                          class="100pxSquare" alt="25"/>

There is the easy way

HTML:

<input type="checkbox" name="test[]" />x
<input type="checkbox" name="test[]"  />y
<input type="checkbox" name="test[]" />z
<button type="button" id="submit">Submit</button>

JQUERY:

$("#submit").on("click",function(){
    if (($("input[name*='test']:checked").length)<=0) {
        alert("You must check at least 1 box");
    }
    return true;
});

For this you not need any plugin. Enjoy;)

From the api on GridLayout:

The container is divided into equal-sized rectangles, and one component is placed in each rectangle.

Try using FlowLayout or GridBagLayout for your set size to be meaningful. Also, @Serplat is correct. You need to use setPreferredSize( Dimension ) instead of setSize( int, int ).

    JPanel displayPanel = new JPanel();
    // JPanel displayPanel = new JPanel( new GridLayout( 4, 2 ) );
    // JPanel displayPanel = new JPanel( new BorderLayout() );
    // JPanel displayPanel = new JPanel( new GridBagLayout() );

    JTextField titleText = new JTextField( "title" );

    titleText.setPreferredSize( new Dimension( 200, 24 ) );

    // For FlowLayout and GridLayout, uncomment:
    displayPanel.add( titleText );

    // For BorderLayout, uncomment:
    // displayPanel.add( titleText, BorderLayout.NORTH );

    // For GridBagLayout, uncomment:
    // displayPanel.add( titleText, new GridBagConstraints( 0, 0, 1, 1, 1.0,
    // 1.0, GridBagConstraints.CENTER, GridBagConstraints.NONE,
    // new Insets( 0, 0, 0, 0 ), 0, 0 ) );

Use access modifier before the member definition:

    private $connection;

As you cannot use function call in member definition in PHP, do it in constructor:

 public function __construct() {
      $this->connection = sqlite_open("[path]/data/users.sqlite", 0666);
 }

I believe this is the simplest way of putting all what it is on the screen into a file. It is a native PS CmdLet so you don't have to change anything in yout script

Start-Transcript -Path Computer.log

Write-Host "everything will end up in Computer.log"

Stop-Transcript

I think your issue is that Range("H18") doesn't contain a formula. Also, you could make your code more efficient by eliminating x. Instead, change your code to

Range("H18").GoalSeek Goal:=Range("H32").Value, ChangingCell:=Range("G18")

I found this vimscript plugin is helpful for this situation.

Plugin 'vim-scripts/PreserveNoEOL'

Or read more at github

I see three possibilities here that will help you insert into your table without making a complete mess but "specifying" a value for the AUTO_INCREMENT column, since you are supplying all the values you can do either one of the following options.

First approach (Supplying NULL):

INSERT INTO test.authors VALUES (
 NULL,'1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',
 '2012-01-03 12:50:59','198963','21','',
 '/usr/local/nagios/libexec/check_ping  5','30','0','4.04159',
 '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',
 '','rta=2.860000m=0%;80;100;0'
);

Second approach (Supplying '' {Simple quotes / apostrophes} although it will give you a warning):

INSERT INTO test.authors VALUES (
 '','1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',
 '2012-01-03 12:50:59','198963','21','',
 '/usr/local/nagios/libexec/check_ping  5','30','0','4.04159',
 '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',
 '','rta=2.860000m=0%;80;100;0'
);

Third approach (Supplying default):

INSERT INTO test.authors VALUES (
 default,'1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',
 '2012-01-03 12:50:59','198963','21','',
 '/usr/local/nagios/libexec/check_ping  5','30','0','4.04159',
 '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',
 '','rta=2.860000m=0%;80;100;0'
);

Either one of these examples should suffice when inserting into that table as long as you include all the values in the same order as you defined them when creating the table.

I think you've forgotten initialize your string "str": You need initialize the string before using strcat. And also you need that tmp were a string, not a single char. Try change this:

char str[1024]; // Only declares size
char tmp = '.';

for

char str[1024] = "Hello World";  //Now you have "Hello World" in str
char tmp[2] = ".";

Note: the question was originally about compilation time, but later it turned out that the OP really meant execution time. But maybe this answer will still be useful for someone.

For Visual Studio: go to Tools / Options / Projects and Solutions / VC++ Project Settings and set Build Timing option to 'yes'. After that the time of every build will be displayed in the Output window.

Java has some seriously weird dns caching behavior. Your best bet is to turn off dns caching or set it to some low number like 5 seconds.

networkaddress.cache.ttl (default: -1)
Indicates the caching policy for successful name lookups from the name service. The value is specified as as integer to indicate the number of seconds to cache the successful lookup. A value of -1 indicates "cache forever".

networkaddress.cache.negative.ttl (default: 10)
Indicates the caching policy for un-successful name lookups from the name service. The value is specified as as integer to indicate the number of seconds to cache the failure for un-successful lookups. A value of 0 indicates "never cache". A value of -1 indicates "cache forever".

• http://java.sun.com/j2se/1.4.2/docs/api/java/net/InetAddress.html

I would put an absolutely positioned, z-index: 100; span (or spans) with the background: url("myImageWithRoundedCorners.jpg"); set on it inside the #mainWrapperDivWithBGImage .

Simpler approach? A little more Pythonic?

>>> ok = "0123456789abcdef"
>>> all(c in ok for c in "123456abc")
True
>>> all(c in ok for c in "hello world")
False

It certainly isn't the most efficient, but it's sure readable.

There are only 3 joins:

• A) Cross Join = Cartesian (E.g: Table A, Table B)
• B) Inner Join = JOIN (E.g: Table A Join/Inner Join Table B)

• C) Outer join:

     There are three type of outer join
     1)  Left Outer Join     = Left Join
     2)  Right Outer Join    = Right Join
     3)  Full Outer Join     = Full Join    
  

Hope it'd help.

Just to highlight @Darkonaut answer because I think it should be more visible.

new_list = [] or new_list = list() are both fine (ignoring performance), but append() returns None, as result you can't do new_list = new_list.append(something).

There was a time when adding strings into an array and finalising the string by using join was the fastest/best method. These days browsers have highly optimised string routines and it is recommended that + and += methods are fastest/best

A While/Wend loop can only be exited prematurely with a GOTO or by exiting from an outer block (Exit sub/function or another exitable loop)

Change to a Do loop instead:

Do While True
    count = count + 1

    If count = 10 Then
        Exit Do
    End If
Loop

Or for looping a set number of times:

for count = 1 to 10
   msgbox count
next

(Exit For can be used above to exit prematurely)

All these should work in theory, but (with Python 2.7.2 on Windows at least) any time you send a custom User-agent header, urllib2 doesn't send that header. If you don't try to send a User-agent header, it sends the default Python / urllib2

None of these methods seem to work for adding User-agent but they work for other headers:

opener = urllib2.build_opener(proxy)
opener.addheaders = {'User-agent':'Custom user agent'}
urllib2.install_opener(opener)

request = urllib2.Request(url, headers={'User-agent':'Custom user agent'})

request.headers['User-agent'] = 'Custom user agent'

request.add_header('User-agent', 'Custom user agent')

If you are using SQL Server, Use the LEN (Length) function:

SELECT EmployeeName FROM EmployeeTable WHERE LEN(EmployeeName) > 4

MSDN for it states:

Returns the number of characters of the specified string expression,
excluding trailing blanks.

Here's the link to the MSDN

For oracle/plsql you can use Length(), mysql also uses Length.

Here is the Oracle documentation:

http://www.techonthenet.com/oracle/functions/length.php

And here is the mySQL Documentation of Length(string):

http://dev.mysql.com/doc/refman/5.1/en/string-functions.html#function_length

For PostgreSQL, you can use length(string) or char_length(string). Here is the PostgreSQL documentation:

http://www.postgresql.org/docs/current/static/functions-string.html#FUNCTIONS-STRING-SQL

First, you gotta put your font as either a .otf or .ttf somewhere on your server.

Then use CSS to declare the new font family like this:

@font-face {
    font-family: MyFont;
    src: url('pathway/myfont.otf'); 
    }

If you link your document to the CSS file that you declared your font family in, you can use that font just like any other font.

The -m option specifies the parent number. This is because a merge commit has more than one parent, and Git does not know automatically which parent was the mainline, and which parent was the branch you want to un-merge.

When you view a merge commit in the output of git log, you will see its parents listed on the line that begins with Merge:

commit 8f937c683929b08379097828c8a04350b9b8e183
Merge: 8989ee0 7c6b236
Author: Ben James <[email protected]>
Date:   Wed Aug 17 22:49:41 2011 +0100

Merge branch 'gh-pages'

Conflicts:
    README

In this situation, git revert 8f937c6 -m 1 will get you the tree as it was in 8989ee0, and git revert -m 2 will reinstate the tree as it was in 7c6b236.

To better understand the parent IDs, you can run:

git log 8989ee0 

and

git log 7c6b236

If you have this setup

/app
   /public/index.html
   /media

Then this should get what you wanted

var express = require('express');
//var server = express.createServer();
// express.createServer()  is deprecated. 
var server = express(); // better instead
server.configure(function(){
  server.use('/media', express.static(__dirname + '/media'));
  server.use(express.static(__dirname + '/public'));
});

server.listen(3000);

The trick is leaving this line as last fallback

  server.use(express.static(__dirname + '/public'));

As for documentation, since Express uses connect middleware, I found it easier to just look at the connect source code directly.

For example this line shows that index.html is supported https://github.com/senchalabs/connect/blob/2.3.3/lib/middleware/static.js#L140

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

hosts0 = open("C:path\\a.txt","r")
hosts1 = open("C:path\\b.txt","r")

lines1 = hosts0.readlines()

for i,lines2 in enumerate(hosts1):
    if lines2 != lines1[i]:
        print "line ", i, " in hosts1 is different \n"
        print lines2
    else:
        print "same"

The above code is working for me. Can you please indicate what error you are facing?

Why not to try this?

Swift code to call inside class:

self.mainFrame.reload()

or external call

myWebV.mainFrame.reload()

In C# Selenium Web Driver I have managed to get it working with the following code:

var alert = TestDriver.SwitchTo().Alert();
alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthUser + Keys.Tab + CurrentTestingConfiguration.Configuration.BasicAuthPassword);
alert.Accept();

Although it seems similar, the following did not work with Firefox (Keys.Tab resets all the form and the password will be written within the user field):

alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthUser);
alert.SendKeys(Keys.Tab);
alert.SendKeys(CurrentTestingConfiguration.Configuration.BasicAuthPassword);

Also, I have tried the following solution which resulted in exception:

var alert = TestDriver.SwitchTo().Alert();
alert.SetAuthenticationCredentials(
   CurrentTestingConfiguration.Configuration.BasicAuthUser,
   CurrentTestingConfiguration.Configuration.BasicAuthPassword);

System.NotImplementedException: 'POST /session/38146c7c-cd1a-42d8-9aa7-1ac6837e64f6/alert/credentials did not match a known command'

This is a simple benchmark:

require 'benchmark'

"test123" =~ /1/
=> 4
Benchmark.measure{ 1000000.times { "test123" =~ /1/ } }
=>   0.610000   0.000000   0.610000 (  0.578133)

"test123"[/1/]
=> "1"
Benchmark.measure{ 1000000.times { "test123"[/1/] } }
=>   0.718000   0.000000   0.718000 (  0.750010)

irb(main):019:0> "test123".match(/1/)
=> #<MatchData "1">
Benchmark.measure{ 1000000.times { "test123".match(/1/) } }
=>   1.703000   0.000000   1.703000 (  1.578146)

So =~ is faster but it depends what you want to have as a returned value. If you just want to check if the text contains a regex or not use =~

Kotlin

data class Player(val name : String, val surname: String)

val json = [
  {
    "name": "name 1",
    "surname": "surname 1"
  },
  {
    "name": "name 2",
    "surname": "surname 2"
  },
  {
    "name": "name 3",
    "surname": "surname 3"
  }
]

val typeToken = object : TypeToken<List<Player>>() {}.type
val playerArray = Gson().fromJson<List<Player>>(json, typeToken)

OR

val playerArray = Gson().fromJson(json, Array<Player>::class.java)

You can use a list for the second generic type. For example a dictionary of strings keyed by a string:

Dictionary<string, List<string>> myDict;

test ! -f README.md || echo 'Support OpenSource!' >> README.md

"If README.md does not exist, do nothing (and exit successfully). Otherwise, append text to the end."

If you use && instead of || then you generate an error when the file doesn't exist:

Makefile:42: recipe for target 'dostuff' failed
make: *** [dostuff] Error 1

This code does exactly what you want. It prevents the image from dragging while allowing any other actions that depend on the event.

$("img").mousedown(function(e){
    e.preventDefault()
});

Only such dialog is FileDialog. Its part of WinForms, but its actually only wrapper around WinAPI standard OS file dialog. And I don't think it is ugly, its actually part of OS, so it looks like OS it is run on.

Other way, there is nothing to help you with. You either need to look for 3rd party implementation, either free (and I don't think there are any good) or paid.

Use System.in, it is an InputStream which just serves this purpose

I was able to find objects by name using below code.

stkMultiChildControl = stkMulti.FindChild<StackPanel>("stkMultiControl_" + couter.ToString());

Here is an example that works on Chrome 5.0.375.125.

The page B (iframe content):

<html>
    <head></head>
    <body>
        <script>
            top.postMessage('hello', 'A');
        </script>
    </body>
</html>

Note the use of top.postMessage or parent.postMessage not window.postMessage here

The page A:

<html>
<head></head>
<body>
    <iframe src="B"></iframe>
    <script>
        window.addEventListener( "message",
          function (e) {
                if(e.origin !== 'B'){ return; } 
                alert(e.data);
          },
          false);
    </script>
</body>
</html>

A and B must be something like http://domain.com

EDIT:

From another question, it looks the domains(A and B here) must have a / for the postMessage to work properly.

iconView = (ImageView) itemLayoutView .findViewById(R.id.iconId);

        itemLayoutView.setOnClickListener(new View.OnClickListener() {

                Intent intent = new Intent(v.getContext(), SecondPage.class);

                Toast.makeText(v.getContext(), "os version is: " + feed.getTitle(), Toast.LENGTH_SHORT).show();

Build Solution - Build solution will build your application with building the number of projects which are having any file change. And it does not clear any existing binary files and just replacing updated assemblies in bin or obj folder.

Rebuild Solution - Rebuild solution will build your entire application with building all the projects are available in your solution with cleaning them. Before building it clears all the binary files from bin and obj folder.

Clean Solution - Clean solution is just clears all the binary files from bin and obj folder.

You open the file in text mode.

More specifically:

ifile  = open('sample.csv', "rt", encoding=<theencodingofthefile>)

Good guesses for encoding is "ascii" and "utf8". You can also leave the encoding off, and it will use the system default encoding, which tends to be UTF8, but may be something else.

Say you have the following DataFrame:

>>> df = pd.DataFrame([['hello', 'hello world'], ['abcd', 'defg']], columns=['a','b'])
>>> df
       a            b
0  hello  hello world
1   abcd         defg

You can always use the in operator in a lambda expression to create your filter.

>>> df.apply(lambda x: x['a'] in x['b'], axis=1)
0     True
1    False
dtype: bool

The trick here is to use the axis=1 option in the apply to pass elements to the lambda function row by row, as opposed to column by column.

If the statements are in the context of how CSS affects HTML then DOM element refers to an HTML element.

Make sure to balance the risk that fresh statistics cause undesirable changes to query plans against the risk that stale statistics can themselves cause query plans to change.

Imagine you have a bug database with a table ISSUE and a column CREATE_DATE where the values in the column increase more or less monotonically. Now, assume that there is a histogram on this column that tells Oracle that the values for this column are uniformly distributed between January 1, 2008 and September 17, 2008. This makes it possible for the optimizer to reasonably estimate the number of rows that would be returned if you were looking for all issues created last week (i.e. September 7 - 13). If the application continues to be used and the statistics are never updated, though, this histogram will be less and less accurate. So the optimizer will expect queries for "issues created last week" to be less and less accurate over time and may eventually cause Oracle to change the query plan negatively.

It has been three years since this question was asked, but I am just now coming across it. Since this answer is so far down the stack, please allow me to repeat it:

Q: I am interested if there are any limits to what types of values can be set using const in JavaScript—in particular functions. Is this valid? Granted it does work, but is it considered bad practice for any reason?

I was motivated to do some research after observing one prolific JavaScript coder who always uses const statement for functions, even when there is no apparent reason/benefit.

In answer to "is it considered bad practice for any reason?" let me say, IMO, yes it is, or at least, there are advantages to using function statement.

It seems to me that this is largely a matter of preference and style. There are some good arguments presented above, but none so clear as is done in this article:

Constant confusion: why I still use JavaScript function statements by medium.freecodecamp.org/Bill Sourour, JavaScript guru, consultant, and teacher.

I urge everyone to read that article, even if you have already made a decision.

Here's are the main points:

Function statements have two clear advantages over [const] function expressions:

Advantage #1: Clarity of intent

When scanning through thousands of lines of code a day, it’s useful to be able to figure out the programmer’s intent as quickly and easily as possible.

Advantage #2: Order of declaration == order of execution

Ideally, I want to declare my code more or less in the order that I expect it will get executed.

This is the showstopper for me: any value declared using the const keyword is inaccessible until execution reaches it.

What I’ve just described above forces us to write code that looks upside down. We have to start with the lowest level function and work our way up.

My brain doesn’t work that way. I want the context before the details.

Most code is written by humans. So it makes sense that most people’s order of understanding roughly follows most code’s order of execution.

You can get all of the table data by using this query:

SHOW TABLE STATUS FROM `DatabaseName` WHERE `name` LIKE 'TableName' ;

You can get exactly this information by using this query:

SELECT `AUTO_INCREMENT`
FROM  INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'DatabaseName'
AND   TABLE_NAME   = 'TableName';

I'm getting best results to put jQuery dialog in the center of browser's window with:

position: { my: "center bottom", at: "center center", of: window },

There's probably more accurate way to position it with option "using" as described in the documentation at http://api.jqueryui.com/position/ but I'm in a hurry...
