Nowadays I include a new attribute "allow" on iframe tag, for example:

allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture"

The final code is:

<iframe src="https://www.youtube.com/embed/[VIDEO-CODE]?autoplay=1" 
frameborder="0" style="width: 100%; height: 100%;"
allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture"></iframe>

I've the same problem, and by the "trial and error" method I have the steps to install the guest additions on a MacOS guest:

1. insert the guest additions cd
2. open the cd on file manager
3. double click on VBoxDarwinAdditions.pkg
4. the installer opens, then click contine
5. next screen to set location of installed files, only press install
6. your password can be asked a couple of time while installing, write it and continue
7. this is the tricky part, on my installation, macos show an message about the driver created by oracle won't be installed because a security issue, it has the option to enable it, so click on the button to open security screen and click on the allow button next to the oracle software listed at bottom of the security settings window, it will ask your password again. Meanwhile the pkg installer continued as if it has permissions and will say "install finished", but I don't believe it so, once I unlocked the oracle drivers installations I repeat the whole process from step 3, and in the second round all installs without asking more than the first password to install.

And it is done!

You need Ajax to make it happen. Something like this:

$(document).ready(function(){
    $("#myform").on('submit', function(){
        var name = $("#name").val();
        var email = $("#email").val();
        var password = $("#password").val();
        var contact = $("#contact").val();

        var dataString = 'name1=' + name + '&email1=' + email + '&password1=' + password + '&contact1=' + contact;
        if(name=='' || email=='' || password=='' || contact=='')
        {
            alert("Please fill in all fields");
        }
        else
        {
            // Ajax code to submit form.
            $.ajax({
                type: "POST",
                url: "ajaxsubmit.php",
                data: dataString,
                cache: false,
                success: function(result){
                    alert(result);
                }
           });
        }
        return false;
    });
});

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

You could wrapping the transaction over try..catch or even reverse them, here my example code I used to in laravel 5,, if you look deep inside DB:transaction() in Illuminate\Database\Connection that the same like you write manual transaction.

Laravel Transaction

public function transaction(Closure $callback)
    {
        $this->beginTransaction();

        try {
            $result = $callback($this);

            $this->commit();
        }

        catch (Exception $e) {
            $this->rollBack();

            throw $e;
        } catch (Throwable $e) {
            $this->rollBack();

            throw $e;
        }

        return $result;
    }

so you could write your code like this, and handle your exception like throw message back into your form via flash or redirect to another page. REMEMBER return inside closure is returned in transaction() so if you return redirect()->back() it won't redirect immediately, because the it returned at variable which handle the transaction.

Wrap Transaction

$result = DB::transaction(function () use ($request, $message) {
   try{

      // execute query 1
      // execute query 2
      // ..

      return redirect(route('account.article'));

   } catch (\Exception $e) {
       return redirect()->back()->withErrors(['error' => $e->getMessage()]);
    }
 });

// redirect the page
return $result;

then the alternative is throw boolean variable and handle redirect outside transaction function or if your need to retrieve why transaction failed you can get it from $e->getMessage() inside catch(Exception $e){...}

This is what I expected to see when I came to this question:

import pandas as pd


df = pd.DataFrame([(1, 2, 3, 4),
                   (5, 6, 7, 8),
                   (9, 0, 1, 2),
                   (3, 4, 5, 6)],
                  columns=list('abcd'),
                  index=['India', 'France', 'England', 'Germany'])
print(df)

gives

I would try to fix saturation and lumination to maximum and focus on hue only. As I see it, H can go from 0 to 255 and then wraps around. Now if you wanted two contrasting colours you would take the opposite sides of this ring, i.e. 0 and 128. If you wanted 4 colours, you would take some separated by 1/4 of the 256 length of the circle, i.e. 0, 64,128,192. And of course, as others suggested when you need N colours, you could just separate them by 256/N.

What I would add to this idea is to use a reversed representation of a binary number to form this sequence. Look at this:

0 = 00000000  after reversal is 00000000 = 0
1 = 00000001  after reversal is 10000000 = 128
2 = 00000010  after reversal is 01000000 = 64
3 = 00000011  after reversal is 11000000 = 192

... this way if you need N different colours you could just take first N numbers, reverse them, and you get as much distant points as possible (for N being power of two) while at the same time preserving that each prefix of the sequence differs a lot.

This was an important goal in my use case, as I had a chart where colors were sorted by area covered by this colour. I wanted the largest areas of the chart to have large contrast, and I was ok with some small areas to have colours similar to those from top 10, as it was obvious for the reader which one is which one by just observing the area.

Use the compareTo method of BigDecimal :

public int compareTo(BigDecimal val) Compares this BigDecimal with the specified BigDecimal.

Returns:
-1, 0, or 1 as this BigDecimal is numerically less than, equal to, or greater than val.

This is now possible directly from nbconvert as of version 5.2.1: content can be filtered using the built-in template exporter exclude options. For example:

jupyter nbconvert --to pdf --TemplateExporter.exclude_input=True my_notebook.ipynb

will exclude the "input code" cells, ie the code itself. Similar options exist to exclude prompts, markdown cells, or outputs, or both inputs and outputs.

(These options should work irrespective of output format.)

Client-side validation was not being executed at all on my web form and I had no idea why. It turns out the problem was the name of the javascript function was the same as the server control ID.

So you can't do this...

<script>
  function vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="vld" />

But this works:

<script>
  function validate_vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="validate_vld" />

I'm guessing it conflicts with internal .NET Javascript?

Set your SMTP auth to true if using the PHPmailer class:

Update Swift 4.1

Here we create a struct to implement the Tuple usage and validate the OTP text length. That needs to be of 2 fields for this example.

struct ValidateOTP {
var code: String
var isValid: Bool }

func validateTheOTP() -> ValidateOTP {
    let otpCode = String(format: "%@%@", txtOtpField1.text!, txtOtpField2.text!)
    if otpCode.length < 2 {
        return ValidateOTP(code: otpCode, isValid: false)
    } else {
        return ValidateOTP(code: otpCode, isValid: true)
    }
}

Usage:

let isValidOTP = validateTheOTP()
    if isValidOTP.isValid { print(" valid OTP") } else {   self.alert(msg: "Please fill the valid OTP", buttons: ["Ok"], handler: nil)
    }

Hope it helps!

What worked for me, is registering it on the Page while specifying the type as that of the UpdatePanel, like so:

Also, your input element seems out of place in your code.

If you're doing this with more than one module and want to have more control over versions, you should look into having your own private npm registry.

This way you can npm publish your modules to your private npm registry and use package.json entries the same way you would for public modules.

Look at Jersey. Again, REST is all about the data. And a tutorial here

The latest version of the official mysql docker image allows you to import data on startup. Here is my docker-compose.yml

data:
  build: docker/data/.
mysql:
  image: mysql
  ports:
    - "3307:3306"
  environment:
    MYSQL_ROOT_PASSWORD: 1234
  volumes:
    - ./docker/data:/docker-entrypoint-initdb.d
  volumes_from:
    - data

Here, I have my data-dump.sql under docker/data which is relative to the folder the docker-compose is running from. I am mounting that sql file into this directory /docker-entrypoint-initdb.d on the container.

If you are interested to see how this works, have a look at their docker-entrypoint.sh in GitHub. They have added this block to allow importing data

    echo
    for f in /docker-entrypoint-initdb.d/*; do
        case "$f" in
            *.sh)  echo "$0: running $f"; . "$f" ;;
            *.sql) echo "$0: running $f"; "${mysql[@]}" < "$f" && echo ;;
            *)     echo "$0: ignoring $f" ;;
        esac
        echo
    done

An additional note, if you want the data to be persisted even after the mysql container is stopped and removed, you need to have a separate data container as you see in the docker-compose.yml. The contents of the data container Dockerfile are very simple.

FROM n3ziniuka5/ubuntu-oracle-jdk:14.04-JDK8

VOLUME /var/lib/mysql

CMD ["true"]

The data container doesn't even have to be in start state for persistence.

Using pure bash :

$ cat file.txt
US/Central - 10:26 PM (CST)
$ while read a b time x; do [[ $b == - ]] && echo $time; done < file.txt

another solution with bash regex :

$ [[ "US/Central - 10:26 PM (CST)" =~ -[[:space:]]*([0-9]{2}:[0-9]{2}) ]] &&
    echo ${BASH_REMATCH[1]}

another solution using grep and look-around advanced regex :

$ echo "US/Central - 10:26 PM (CST)" | grep -oP "\-\s+\K\d{2}:\d{2}"

another solution using sed :

$ echo "US/Central - 10:26 PM (CST)" |
    sed 's/.*\- *\([0-9]\{2\}:[0-9]\{2\}\).*/\1/'

another solution using perl :

$ echo "US/Central - 10:26 PM (CST)" |
    perl -lne 'print $& if /\-\s+\K\d{2}:\d{2}/'

and last one using awk :

$ echo "US/Central - 10:26 PM (CST)" |
    awk '{for (i=0; i<=NF; i++){if ($i == "-"){print $(i+1);exit}}}'

you can check that by either isset() or empty() (its check explicit isset) weather check box is checked or not

for example

  <input type='checkbox' name='Mary' value='2' id='checkbox' />

here you can check by

if (isset($_POST['Mary'])) {
    echo "checked!";
}

or

if (!empty($_POST['Mary'])) {
    echo "checked!";
}

the above will check only one if you want to do for many than you can make an array instead writing separate for all checkbox try like

<input type="checkbox" name="formDoor[]" value="A" />Acorn Building<br />
<input type="checkbox" name="formDoor[]" value="B" />Brown Hall<br />
<input type="checkbox" name="formDoor[]" value="C" />Carnegie Complex<br />

php

  $aDoor = $_POST['formDoor'];
  if(empty($aDoor))
  {
    echo("You didn't select any buildings.");
  }
  else
  {
    $N = count($aDoor);
    echo("You selected $N door(s): ");
    for($i=0; $i < $N; $i++)
    {
      echo htmlspecialchars($aDoor[$i] ). " ";
    }
  }

With pure JS:

var userIds = users.map( function(obj) { return obj.id; } );

Update - the answer below was written before C# 6 came along. In C# 6 you can write:

public class Foo
{
    public string Bar { get; set; } = "bar";
}

You can also write read-only automatically-implemented properties, which are only writable in the constructor (but can also be given a default initial value):

public class Foo
{
    public string Bar { get; }

    public Foo(string bar)
    {
        Bar = bar;
    }
}

It's unfortunate that there's no way of doing this right now. You have to set the value in the constructor. (Using constructor chaining can help to avoid duplication.)

Automatically implemented properties are handy right now, but could certainly be nicer. I don't find myself wanting this sort of initialization as often as a read-only automatically implemented property which could only be set in the constructor and would be backed by a read-only field.

This hasn't happened up until and including C# 5, but is being planned for C# 6 - both in terms of allowing initialization at the point of declaration, and allowing for read-only automatically implemented properties to be initialized in a constructor body.

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:

Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

You can try to use the runner in atom Hit Ctrl+R (Alt+R on Win/Linux) to launch the runner for the active window. Hit Ctrl+Shift+R (Alt+Shift+R on Win/Linux) to run the currently selected text in the active window. Hit Ctrl+Shift+C to kill a currently running process. Hit Escape to close the runner window

This will work for me:

I am trying to understand what Python's descriptors are and what they can be useful for.

Descriptors are class attributes (like properties or methods) with any of the following special methods:

• __get__ (non-data descriptor method, for example on a method/function)
• __set__ (data descriptor method, for example on a property instance)
• __delete__ (data descriptor method)

These descriptor objects can be used as attributes on other object class definitions. (That is, they live in the __dict__ of the class object.)

Descriptor objects can be used to programmatically manage the results of a dotted lookup (e.g. foo.descriptor) in a normal expression, an assignment, and even a deletion.

Functions/methods, bound methods, property, classmethod, and staticmethod all use these special methods to control how they are accessed via the dotted lookup.

A data descriptor, like property, can allow for lazy evaluation of attributes based on a simpler state of the object, allowing instances to use less memory than if you precomputed each possible attribute.

Another data descriptor, a member_descriptor, created by __slots__, allow memory savings by allowing the class to store data in a mutable tuple-like datastructure instead of the more flexible but space-consuming __dict__.

Non-data descriptors, usually instance, class, and static methods, get their implicit first arguments (usually named cls and self, respectively) from their non-data descriptor method, __get__.

Most users of Python need to learn only the simple usage, and have no need to learn or understand the implementation of descriptors further.

In Depth: What Are Descriptors?

A descriptor is an object with any of the following methods (__get__, __set__, or __delete__), intended to be used via dotted-lookup as if it were a typical attribute of an instance. For an owner-object, obj_instance, with a descriptor object:

• obj_instance.descriptor invokes
  descriptor.__get__(self, obj_instance, owner_class) returning a value
  This is how all methods and the get on a property work.

• obj_instance.descriptor = value invokes
  descriptor.__set__(self, obj_instance, value) returning None
  This is how the setter on a property works.

• del obj_instance.descriptor invokes
  descriptor.__delete__(self, obj_instance) returning None
  This is how the deleter on a property works.

obj_instance is the instance whose class contains the descriptor object's instance. self is the instance of the descriptor (probably just one for the class of the obj_instance)

To define this with code, an object is a descriptor if the set of its attributes intersects with any of the required attributes:

def has_descriptor_attrs(obj):
    return set(['__get__', '__set__', '__delete__']).intersection(dir(obj))

def is_descriptor(obj):
    """obj can be instance of descriptor or the descriptor class"""
    return bool(has_descriptor_attrs(obj))

A Data Descriptor has a __set__ and/or __delete__.
A Non-Data-Descriptor has neither __set__ nor __delete__.

def has_data_descriptor_attrs(obj):
    return set(['__set__', '__delete__']) & set(dir(obj))

def is_data_descriptor(obj):
    return bool(has_data_descriptor_attrs(obj))

Builtin Descriptor Object Examples:

• classmethod
• staticmethod
• property
• functions in general

Non-Data Descriptors

We can see that classmethod and staticmethod are Non-Data-Descriptors:

>>> is_descriptor(classmethod), is_data_descriptor(classmethod)
(True, False)
>>> is_descriptor(staticmethod), is_data_descriptor(staticmethod)
(True, False)

Both only have the __get__ method:

>>> has_descriptor_attrs(classmethod), has_descriptor_attrs(staticmethod)
(set(['__get__']), set(['__get__']))

Note that all functions are also Non-Data-Descriptors:

>>> def foo(): pass
... 
>>> is_descriptor(foo), is_data_descriptor(foo)
(True, False)

Data Descriptor, property

However, property is a Data-Descriptor:

>>> is_data_descriptor(property)
True
>>> has_descriptor_attrs(property)
set(['__set__', '__get__', '__delete__'])

Dotted Lookup Order

These are important distinctions, as they affect the lookup order for a dotted lookup.

obj_instance.attribute

1. First the above looks to see if the attribute is a Data-Descriptor on the class of the instance,
2. If not, it looks to see if the attribute is in the obj_instance's __dict__, then
3. it finally falls back to a Non-Data-Descriptor.

The consequence of this lookup order is that Non-Data-Descriptors like functions/methods can be overridden by instances.

Recap and Next Steps

We have learned that descriptors are objects with any of __get__, __set__, or __delete__. These descriptor objects can be used as attributes on other object class definitions. Now we will look at how they are used, using your code as an example.

Analysis of Code from the Question

Here's your code, followed by your questions and answers to each:

class Celsius(object):
    def __init__(self, value=0.0):
        self.value = float(value)
    def __get__(self, instance, owner):
        return self.value
    def __set__(self, instance, value):
        self.value = float(value)

class Temperature(object):
    celsius = Celsius()

1. Why do I need the descriptor class?

Your descriptor ensures you always have a float for this class attribute of Temperature, and that you can't use del to delete the attribute:

>>> t1 = Temperature()
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

Otherwise, your descriptors ignore the owner-class and instances of the owner, instead, storing state in the descriptor. You could just as easily share state across all instances with a simple class attribute (so long as you always set it as a float to the class and never delete it, or are comfortable with users of your code doing so):

class Temperature(object):
    celsius = 0.0

This gets you exactly the same behavior as your example (see response to question 3 below), but uses a Pythons builtin (property), and would be considered more idiomatic:

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

2. What is instance and owner here? (in get). What is the purpose of these parameters?

instance is the instance of the owner that is calling the descriptor. The owner is the class in which the descriptor object is used to manage access to the data point. See the descriptions of the special methods that define descriptors next to the first paragraph of this answer for more descriptive variable names.

3. How would I call/use this example?

Here's a demonstration:

>>> t1 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1
>>> 
>>> t1.celsius
1.0
>>> t2 = Temperature()
>>> t2.celsius
1.0

You can't delete the attribute:

>>> del t2.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: __delete__

And you can't assign a variable that can't be converted to a float:

>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 7, in __set__
ValueError: invalid literal for float(): 0x02

Otherwise, what you have here is a global state for all instances, that is managed by assigning to any instance.

The expected way that most experienced Python programmers would accomplish this outcome would be to use the property decorator, which makes use of the same descriptors under the hood, but brings the behavior into the implementation of the owner class (again, as defined above):

class Temperature(object):
    _celsius = 0.0
    @property
    def celsius(self):
        return type(self)._celsius
    @celsius.setter
    def celsius(self, value):
        type(self)._celsius = float(value)

Which has the exact same expected behavior of the original piece of code:

>>> t1 = Temperature()
>>> t2 = Temperature()
>>> t1.celsius
0.0
>>> t1.celsius = 1.0
>>> t2.celsius
1.0
>>> del t1.celsius
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: can't delete attribute
>>> t1.celsius = '0x02'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 8, in celsius
ValueError: invalid literal for float(): 0x02

Conclusion

We've covered the attributes that define descriptors, the difference between data- and non-data-descriptors, builtin objects that use them, and specific questions about use.

So again, how would you use the question's example? I hope you wouldn't. I hope you would start with my first suggestion (a simple class attribute) and move on to the second suggestion (the property decorator) if you feel it is necessary.

I'm not a 100% sure, but won't

$(data)

produce a jquery object with a DOM for that data, not connected anywhere? Or if it's already parsed as a DOM, you could just go $("#myImg", data), or whatever selector suits your needs.

EDIT
Rereading your question it appears your 'data' is already a DOM, which means you could just go (assuming there's only an img in your DOM, otherwise you'll need a more precise selector)

$("img", data).attr ("src")

if you want to access the src-attribute. If your data is just text, it would probably work to do

$("img", $(data)).attr ("src")

Just check for

if(table.rows[0][0] == null)
{
     //Whatever I want to do
}

or you could

if(t.Rows[0].IsNull(0))
{
     //Whatever I want to do
}

You need to install Dot Net 4.0.2 or above as mentioned here.
The 4.0 bits don't understand the syntax required by LocalDB

Have you tried:

#!/usr/local/bin/php

I.e. without the -q part? That's what the error message "Could not open input file: -q" means. The first argument to php if it doesn't look like an option is the name of the PHP file to execute, and -q is CGI only.

EDIT: A couple of (non-related) tips:

1. You don't need to terminate the last block of PHP with ?>. In fact, it is often better not to.
2. When executed on the command line, PHP defines the global constant STDIN to fopen("php://stdin", "r"). You can use that instead of opening "php://stdin" a second time: $fd = STDIN;

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

In order to support refactoring correctly (rename class), then you should use either:

 MyClass.class.getName(); // full name with package

or (thanks to @James Van Huis):

 MyClass.class.getSimpleName(); // class name and no more

Yes ..it is possible using INSERT ON DUPLICATE KEY UPDATE sql statement.. syntax: INSERT INTO table_name (a,b,c) VALUES (1,2,3),(4,5,6) ON DUPLICATE KEY UPDATE a=VALUES(a),b=VALUES(b),c=VALUES(c)

Other answers rightly point out that there is no need to use jQuery in order to navigate to another URL; that's why there's no jQuery function which does so!

If you're asking how to click a link via jQuery then assuming you have markup which looks like:

<a id="my-link" href="/relative/path.html">Click Me!</a>

You could click() it by executing:

$('#my-link').click();

Note that the if $myVar; then ... ;fi construct has a security problem you might want to avoid with

case $myvar in
  (true)    echo "is true";;
  (false)   echo "is false";;
  (rm -rf*) echo "I just dodged a bullet";;
esac

You might also want to rethink why if [ "$myvar" = "true" ] appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case solution is also handled without forks.

As the message error says, you need to Increase the length of your column to fit the length of the data you are trying to insert (0000-00-00)

EDIT 1:

Following your comment, I run a test table:

mysql> create table testDate(id int(2) not null auto_increment, pdd date default null, primary key(id));
Query OK, 0 rows affected (0.20 sec)

Insertion:

mysql> insert into testDate values(1,'0000-00-00');
Query OK, 1 row affected (0.06 sec)

EDIT 2:

So, aparently you want to insert a NULL value to pdd field as your comment states ? You can do that in 2 ways like this:

Method 1:

mysql> insert into testDate values(2,'');
Query OK, 1 row affected, 1 warning (0.06 sec)

Method 2:

mysql> insert into testDate values(3,NULL);
Query OK, 1 row affected (0.07 sec)

EDIT 3:

You failed to change the default value of pdd field. Here is the syntax how to do it (in my case, I set it to NULL in the start, now I will change it to NOT NULL)

mysql> alter table testDate modify pdd date not null;
Query OK, 3 rows affected, 1 warning (0.60 sec)
Records: 3  Duplicates: 0  Warnings: 1

That variable isn't stored in some script. It's simply set by the X server scripts. You can check the environment variables currently set using set.

You can create an XML file in the drawable folder. Call it, for example, shape.xml

In shape.xml:

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"   >

    <solid
        android:color="#888888" >
    </solid>

    <stroke
        android:width="2dp"
        android:color="#C4CDE0" >
    </stroke>

    <padding
        android:left="5dp"
        android:top="5dp"
        android:right="5dp"
        android:bottom="5dp"    >
    </padding>

    <corners
        android:radius="11dp"   >
    </corners>

</shape>

The <corner> tag is for your specific question.

Make changes as required.

And in your whatever_layout_name.xml:

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_margin="5dp"
    android:background="@drawable/shape"    >
</LinearLayout>

This is what I usually do in my apps. Hope this helps....

If we use runnable method SwingUtilities.invokeLater() while using Document listener application is getting stuck sometimes and taking time to update the result(As per my experiment). Instead of that we can also use KeyReleased event for text field change listener as mentioned here.

usernameTextField.addKeyListener(new KeyAdapter() {
    public void keyReleased(KeyEvent e) {
        JTextField textField = (JTextField) e.getSource();
        String text = textField.getText();
        textField.setText(text.toUpperCase());
    }
});

A continue statement without a label will re-execute from the condition the innermost while or do loop, and from the update expression of the innermost for loop. It is often used to early-terminate a loop's processing and thereby avoid deeply-nested if statements. In the following example continue will get the next line, without processing the following statement in the loop.

while (getNext(line)) {
  if (line.isEmpty() || line.isComment())
    continue;
  // More code here
}

With a label, continue will re-execute from the loop with the corresponding label, rather than the innermost loop. This can be used to escape deeply-nested loops, or simply for clarity.

Sometimes continue is also used as a placeholder in order to make an empty loop body more clear.

for (count = 0; foo.moreData(); count++)
  continue;

The same statement without a label also exists in C and C++. The equivalent in Perl is next.

This type of control flow is not recommended, but if you so choose you can also use continue to simulate a limited form of goto. In the following example the continue will re-execute the empty for (;;) loop.

aLoopName: for (;;) {
  // ...
  while (someCondition)
  // ...
    if (otherCondition)
      continue aLoopName;

Since the FragmentManager will take care of restoring your Fragments for you as soon as the onResume() method is called I have the fragment call out to the activity and add itself to a list. In my instance I am storing all of this in my PagerAdapter implementation. Each fragment knows it's position because it is added to the fragment arguments on creation. Now whenever I need to manipulate a fragment at a specific index all I have to do is use the list from my adapter.

The following is an example of an Adapter for a custom ViewPager that will grow the fragment as it moves into focus, and scale it down as it moves out of focus. Besides the Adapter and Fragment classes I have here all you need is for the parent activity to be able to reference the adapter variable and you are set.

On EF core you cannot create Indexes using data annotations.But you can do it using the Fluent API.

Like this inside your {Db}Context.cs:

protected override void OnModelCreating(ModelBuilder builder)
{
    builder.Entity<User>()
        .HasIndex(u => u.Email)
        .IsUnique();
}

...or if you're using the overload with the buildAction:

protected override void OnModelCreating(ModelBuilder builder)
{
    builder.Entity<User>(entity => {
        entity.HasIndex(e => e.Email).IsUnique();
    });
}

You can read more about it here : Indexes

Since Java 8, the best answer is to use Consumer<T>:

https://docs.oracle.com/javase/8/docs/api/java/util/function/Consumer.html

It's one of the functional interfaces, which means you can call it as a lambda expression:

void doSomething(Consumer<String> something) {
    something.accept("hello!");
}

...

doSomething( (something) -> System.out.println(something) )

The problem with just using dirname(__FILE__) is that it doesn't follow symlinks. I had to use this for my script to follow the symlink to the actual file location.

use File::Basename;
my $script_dir = undef;
if(-l __FILE__) {
  $script_dir = dirname(readlink(__FILE__));
}
else {
  $script_dir = dirname(__FILE__);
}

    RadioGroup radioGroup = new RadioGroup(WvActivity.this);
    RadioButton radioBtn1 = new RadioButton(this);
    RadioButton radioBtn2 = new RadioButton(this);
    RadioButton radioBtn3 = new RadioButton(this);

    radioBtn1.setText("Less");
    radioBtn2.setText("Normal");
    radioBtn3.setText("More");


    radioGroup.addView(radioBtn1);
    radioGroup.addView(radioBtn2);
    radioGroup.addView(radioBtn3);

    radioGroup.check(radioBtn2.getId());

True is 1 in Python, and likewise False is 0^*:

>>> True == 1
True
>>> False == 0
True

You should be able to perform any operations you want on them by just treating them as though they were numbers, as they are numbers:

>>> issubclass(bool, int)
True
>>> True * 5
5

So to answer your question, no work necessary - you already have what you are looking for.

^{* Note I use is as an English word, not the Python keyword is - True will not be the same object as any random 1.}

Use android.support.v4.app for FragmentManager & FragmentTransaction in your code, it has worked for me.

DetailsFragment detailsFragment = new DetailsFragment();
android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
android.support.v4.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.details,detailsFragment);
fragmentTransaction.commit();

Basically indexOf() is a method belongs to string(array object also), But while calling the function you are passing a number, try to cast it to a string and pass it.

document.getElementById("oset").innerHTML = timeD2C(timeofday + "");

 var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;_x000D_
_x000D_
_x000D_
_x000D_
_x000D_
 function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)_x000D_
    var pos = time.indexOf('.');_x000D_
    var hrs = time.substr(1, pos - 1);_x000D_
    var min = (time.substr(pos, 2)) * 60;_x000D_
_x000D_
    if (hrs > 11) {_x000D_
        hrs = (hrs - 12) + ":" + min + " PM";_x000D_
    } else {_x000D_
        hrs += ":" + min + " AM";_x000D_
    }_x000D_
    return hrs;_x000D_
}_x000D_
alert(timeD2C(timeofday+""));

And it is good to do the string conversion inside your function definition,

function timeD2C(time) { 
  time = time + "";
  var pos = time.indexOf('.');

So that the code flow won't break at times when devs forget to pass a string into this function.

I fixed this error on Ubuntu by carefully following the instructions for installing R. This included:

1. adding deb http://cran.utstat.utoronto.ca/bin/linux/ubuntu trusty/ to my /etc/apt/sources.list file
2. Running sudo apt-get update
3. Running sudo apt-get install r-base-dev

For step 1 you can chose any CRAN download mirror in place of my University of Toronto one if you would like.

No, that's pretty much it. In theory you could use visibility: collapse on some <col>?s to do it, but browser support isn't all there.

To improve what you've got slightly, you could use table-layout: fixed on the <table> to allow the browser to use the simpler, faster and more predictable fixed-table-layout algorithm. You could also drop the .show rules as when a cell isn't made display: none by a .hide rule it will automatically be display: table-cell. Allowing table display to revert to default rather than setting it explicitly avoids problems in IE<8, where the table display values are not supported.

Use CHAR_LENGTH() instead-of LENGTH() as suggested in: MySQL - length() vs char_length()

SELECT name, CHAR_LENGTH(name) AS mlen FROM mytable ORDER BY mlen DESC LIMIT 1

I figured out the solution:

• I had to delete my anaconda and python installations
• Re-install Anaconda only
• Open Anaconda prompt and point it to Anaconda/Scripts
• Run pip install google
• Run the sample code now from Spyder.

No more errors.

Lets say your data is -

data = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }

You can use the data.items() method to get the dictionary elements. Note, in django templates we do NOT put (). Also some users mentioned values[0] does not work, if that is the case then try values.items.

<table>
    <tr>
        <td>a</td>
        <td>b</td>
        <td>c</td>
    </tr>

    {% for key, values in data.items %}
    <tr>
        <td>{{key}}</td>
        {% for v in values[0] %}
        <td>{{v}}</td>
        {% endfor %}
    </tr>
    {% endfor %}
</table>

Am pretty sure you can extend this logic to your specific dict.

To iterate over dict keys in a sorted order - First we sort in python then iterate & render in django template.

return render_to_response('some_page.html', {'data': sorted(data.items())})

In template file:

{% for key, value in data %}
    <tr>
        <td> Key: {{ key }} </td> 
        <td> Value: {{ value }} </td>
    </tr>
{% endfor %}

jezrael's answer is good, but did not answer a question I had: Will getting the "sort" flag wrong mess up my data in any way? The answer is apparently "no", you are fine either way.

from pandas import DataFrame, concat

You've created a new repository and added some files to the index, but you haven't created your first commit yet. After you've done:

 git add a_text_file.txt 

... do:

 git commit -m "Initial commit."

... and those errors should go away.

I have declared a list of Integers.

ArrayList<Integer> numberList = new ArrayList<Integer>(Arrays.asList(1, 2, 3, 4, 5));

You can try using these different ways below.

Using mapToInt

int sum = numberList.stream().mapToInt(Integer::intValue).sum();

Using summarizingInt

int sum = numberList.stream().collect(Collectors.summarizingInt(Integer::intValue)).getSum();

Using reduce

int sum = numberList.stream().reduce(Integer::sum).get().intValue();

Even i ran into the same issue with mysql and liquibase. So this is what the problem is: The table from which you want to reference a column of other table is different either in case of datatype or in terms of size of the datatype.

Error appears in below scenario:
Scenario 1:
Table A has column id, type=bigint
Table B column referenced_id type varchar(this column gets the value from the id column of Table A.)
Liquibase changeset for table B:

    <changeset id="XXXXXXXXXXX-1" author="xyz">
            <column name="referenced_id" **type="varchar"**>
        </column>
            </changeset>
    <changeSet id="XXXXXXXXXXX-2" author="xyz">
                <addForeignKeyConstraint constraintName="FK_table_A"
                    referencedTableName="A" **baseColumnNames="referenced_id**"
                    referencedColumnNames="id" baseTableName="B" />
    </changeSet>

Table A changeSet:

    <changeSet id="YYYYYYYYYY" author="xyz">
     <column **name="id"** **type="bigint"** autoIncrement="${autoIncrement}">
                    <constraints primaryKey="true" nullable="false"/>
                </column>
    </changeSet>

Solution: 
correct the type of table B to bigint because the referenced table has type bigint.

Scenrario 2:
The type might be correct but the size might not.
e.g. :
Table B : referenced column type="varchar 50"
Table A : base column type ="varchar 255"

Solution change the size of referenced column to that of base table's column size.

• public Exception() -- This constructs an Exception without any additional information.Nature of the exception is typically inferred from the class name.
• public Exception(String s) -- Constructs an exception with specified error message.A detail message is a String that describes the error condition for this particular exception.

3 approaches for creating a fullscreen iframe:

• Approach 1 - Viewport-percentage lengths

  In supported browsers, you can use viewport-percentage lengths such as height: 100vh.

  Where 100vh represents the height of the viewport, and likewise 100vw represents the width.

  Example Here

  _x000D_

  _x000D_

  body {_x000D_
      margin: 0;            /* Reset default margin */_x000D_
  }_x000D_
  iframe {_x000D_
      display: block;       /* iframes are inline by default */_x000D_
      background: #000;_x000D_
      border: none;         /* Reset default border */_x000D_
      height: 100vh;        /* Viewport-relative units */_x000D_
      width: 100vw;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

• Approach 2 - Fixed positioning

  This approach is fairly straight-forward. Just set the positioning of the fixed element and add a height/width of 100%.

  Example Here

  _x000D_

  _x000D_

  iframe {_x000D_
      position: fixed;_x000D_
      background: #000;_x000D_
      border: none;_x000D_
      top: 0; right: 0;_x000D_
      bottom: 0; left: 0;_x000D_
      width: 100%;_x000D_
      height: 100%;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

• Approach 3

  For this last method, just set the height of the body/html/iframe elements to 100%.

  Example Here

  _x000D_

  _x000D_

  html, body {_x000D_
      height: 100%;_x000D_
      margin: 0;         /* Reset default margin on the body element */_x000D_
  }_x000D_
  iframe {_x000D_
      display: block;       /* iframes are inline by default */_x000D_
      background: #000;_x000D_
      border: none;         /* Reset default border */_x000D_
      width: 100%;_x000D_
      height: 100%;_x000D_
  }

  _x000D_

  <iframe></iframe>

  _x000D_

  _x000D_
  _x000D_

Set this to False on your web.config

<compilation debug="false" targetFramework="4.6.1" />

You mentioned getting the result list from the Query, since you don't know that there is a UniqueResult (hence the exception) you could use list and check the size?

if (query.list().size() == 1) 

Since you're not doing a get() to get your unique object a query will be executed whether you call uniqueResult or list.

I created an extension method on ObjectStateEntry to be able to flag properties (of Entity Framework POCO classes) as modified in a type safe manner, since the default method only accepts a string. Here's my way of getting the name from the property:

public static void SetModifiedProperty<T>(this System.Data.Objects.ObjectStateEntry state, Expression<Func<T>> action)
{
    var body = (MemberExpression)action.Body;
    string propertyName = body.Member.Name;

    state.SetModifiedProperty(propertyName);
}

window load will wait for all resources to be loaded.

document ready waits for the document to be initialized.

unload well, waits till the document is being unloaded.

the order is: document ready, window load, ... ... ... ... window unload.

always use document ready unless you need to wait for your images to load.

shorthand for document ready:

$(function(){
    // yay!
});

I've used the following code a few times and it works sweet:

$("body").click(function(e){ 
    // Check what has been clicked:
    var target = $(e.target); 
    if(target.is("#target")){
    // The target was clicked
    // Do something...
  }
});

You can't "directly" mock static method (hence extension method) with mocking framework. You can try Moles (http://research.microsoft.com/en-us/projects/pex/downloads.aspx), a free tool from Microsoft that implements a different approach. Here is the description of the tool:

Moles is a lightweight framework for test stubs and detours in .NET that is based on delegates.

Moles may be used to detour any .NET method, including non-virtual/static methods in sealed types.

You can use Moles with any testing framework (it's independent about that).

For those of not crazy about VB, here it is in c#:

Note, you have to add a reference to Microsoft Shell Controls and Automation from the COM tab of the References dialog.

public static void Main(string[] args)
{
    List<string> arrHeaders = new List<string>();

    Shell32.Shell shell = new Shell32.Shell();
    Shell32.Folder objFolder;

    objFolder = shell.NameSpace(@"C:\temp\testprop");

    for( int i = 0; i < short.MaxValue; i++ )
    {
        string header = objFolder.GetDetailsOf(null, i);
        if (String.IsNullOrEmpty(header))
            break;
        arrHeaders.Add(header);
    }

    foreach(Shell32.FolderItem2 item in objFolder.Items())
    {
        for (int i = 0; i < arrHeaders.Count; i++)
        {
            Console.WriteLine(
              $"{i}\t{arrHeaders[i]}: {objFolder.GetDetailsOf(item, i)}");
        }
    }
}

write a button tag and on click function

var x = document.getElementById('codeRefer').innerHTML;
  document.getElementById('codeRefer').innerHTML = x;

write this all in onclick function

I know this is an old thread, but I was running into the same problem and found HashSet to be very unreliable because given the same seed, GetHashCode() returned different codes. So, I thought, why not just use a List and hide the add method like this

public class UniqueList<T> : List<T>
{
    public new void Add(T obj)
    {
        if(!Contains(obj))
        {
            base.Add(obj);
        }
    }
}

Because List uses the Equals method solely to determine equality, you can define the Equals method on your T type to make sure you get the desired results.

1. use single quotes for strings
2. do NOT put single quotes around table names(use ` instead)
3. do NOT put single quotes around numbers (you can, but it's harder to read)
4. do NOT put AND between ORDER BY and LIMIT
5. do NOT put = between ORDER BY, LIMIT keywords and condition

So you query will look like:

SELECT post_datetime 
FROM post 
WHERE type = 'published' 
ORDER BY post_datetime DESC 
LIMIT 3

This worked for me.

Locate config.sample.inc.php

Change

$cfg['Servers'][$i]['host'] = 'localhost';

into

$cfg['Servers'][$i]['host'] = '127.0.0.1';

Save.

Then rename the file and remove sample from the name.

Yes there is:

ARRAY=()
ARRAY+=('foo')
ARRAY+=('bar')

Bash Reference Manual:

In the context where an assignment statement is assigning a value to a shell variable or array index (see Arrays), the ‘+=’ operator can be used to append to or add to the variable's previous value.

An easier way to determine what dependencies a native DLL has is to use Dependency Walker - http://www.dependencywalker.com/

I analysed the native DLL and discovered that it depended on MSVCR120.DLL and MSVCP120.DLL, both of which were not installed on my staging server in the System32 directory. I installed the C++ runtime on my staging server and the issue was resolved.

If you have Perl:

perl -pe 's/^/PREFIX/' input.file

You should add the catch() to the end of the Api call. When your code hits the catch() it doesn't return anything, so data is undefined when you try to use setState() on it. The error message actually tells you this too :)

Try using different quotes for "y" as the identifier quote character is the backtick (“`”). Otherwise MySQL "thinks" that you point to a column named "y".

See also MySQL 5 Documentation

Solved similar issue by doing this:

export interface IItem extends Record<string, any> {
    itemId: string;
    price: number;
}

const item: IItem = { itemId: 'someId', price: 200 };
const fieldId = 'someid';

// gives you no errors and proper typing
item[fieldId]

As Matt said, the curly braces are for concatenation. The extra curly braces around 16{a[15]} are the replication operator. They are described in the IEEE Standard for Verilog document (Std 1364-2005), section "5.1.14 Concatenations".

{16{a[15]}}

is the same as

{ 
   a[15], a[15], a[15], a[15], a[15], a[15], a[15], a[15],
   a[15], a[15], a[15], a[15], a[15], a[15], a[15], a[15]
}

In bit-blasted form,

assign result = {{16{a[15]}}, {a[15:0]}};

is the same as:

assign result[ 0] = a[ 0];
assign result[ 1] = a[ 1];
assign result[ 2] = a[ 2];
assign result[ 3] = a[ 3];
assign result[ 4] = a[ 4];
assign result[ 5] = a[ 5];
assign result[ 6] = a[ 6];
assign result[ 7] = a[ 7];
assign result[ 8] = a[ 8];
assign result[ 9] = a[ 9];
assign result[10] = a[10];
assign result[11] = a[11];
assign result[12] = a[12];
assign result[13] = a[13];
assign result[14] = a[14];
assign result[15] = a[15];
assign result[16] = a[15];
assign result[17] = a[15];
assign result[18] = a[15];
assign result[19] = a[15];
assign result[20] = a[15];
assign result[21] = a[15];
assign result[22] = a[15];
assign result[23] = a[15];
assign result[24] = a[15];
assign result[25] = a[15];
assign result[26] = a[15];
assign result[27] = a[15];
assign result[28] = a[15];
assign result[29] = a[15];
assign result[30] = a[15];
assign result[31] = a[15];

I was having this same problem, so I went ahead and wrote a plugin for it.

$(selector).waitUntilExists(function);

Code:

;(function ($, window) {

var intervals = {};
var removeListener = function(selector) {

    if (intervals[selector]) {

        window.clearInterval(intervals[selector]);
        intervals[selector] = null;
    }
};
var found = 'waitUntilExists.found';

/**
 * @function
 * @property {object} jQuery plugin which runs handler function once specified
 *           element is inserted into the DOM
 * @param {function|string} handler 
 *            A function to execute at the time when the element is inserted or 
 *            string "remove" to remove the listener from the given selector
 * @param {bool} shouldRunHandlerOnce 
 *            Optional: if true, handler is unbound after its first invocation
 * @example jQuery(selector).waitUntilExists(function);
 */

$.fn.waitUntilExists = function(handler, shouldRunHandlerOnce, isChild) {

    var selector = this.selector;
    var $this = $(selector);
    var $elements = $this.not(function() { return $(this).data(found); });

    if (handler === 'remove') {

        // Hijack and remove interval immediately if the code requests
        removeListener(selector);
    }
    else {

        // Run the handler on all found elements and mark as found
        $elements.each(handler).data(found, true);

        if (shouldRunHandlerOnce && $this.length) {

            // Element was found, implying the handler already ran for all 
            // matched elements
            removeListener(selector);
        }
        else if (!isChild) {

            // If this is a recurring search or if the target has not yet been 
            // found, create an interval to continue searching for the target
            intervals[selector] = window.setInterval(function () {

                $this.waitUntilExists(handler, shouldRunHandlerOnce, true);
            }, 500);
        }
    }

    return $this;
};

}(jQuery, window));

Solution is to change Delimiter.

Content of the csv file -> Note .. Also space and , in value

Values are 6 Dutch word aap,noot,mies,Piet, Gijs, Jan

Col1;Col2;Col3

a,ap;noo,t;mi es

P,iet;G ,ijs;Ja ,n



$csv = Import-Csv C:\TejaCopy.csv -Delimiter ';' 

Answer:

Write-Host $csv
@{Col1=a,ap; Col2=noo,t; Col3=mi es} @{Col1=P,iet; Col2=G ,ijs; Col3=Ja ,n}

It is possible to read a CSV file and use other Delimiter to separate each column.

It worked for my script :-)

Pushing to the limits corner radius up to get a circle:

    self.btnFoldButton.layer.cornerRadius = self.btnFoldButton.frame.height/2.0;

If button frame is an square it does not matter frame.height or frame.width. Otherwise use the largest of both ones.

Assuming that your table name is city and your existing Primary Key is pk_city, you should be able to do the following:

ALTER TABLE city
DROP CONSTRAINT pk_city;

ALTER TABLE city
ADD CONSTRAINT pk_city PRIMARY KEY (city_id, buildtime, time);

Make sure that there are no records where time is NULL, otherwise you won't be able to re-create the constraint.

$date = strtotime("+1 day");
echo date('m-d-y',$date);

EDIT: I hadn't noticed you needed the position as well. You can't use IndexOf directly on a value of an array type, because it's implemented explicitly. However, you can use:

IList<string> arrayAsList = (IList<string>) stringArray;
int index = arrayAsList.IndexOf(value);
if (index != -1)
{
    ...
}

(This is similar to calling Array.IndexOf as per Darin's answer - just an alternative approach. It's not clear to me why IList<T>.IndexOf is implemented explicitly in arrays, but never mind...)

Updates an old config with new/changed/removed options.

This error happens because of your Jre version of Eclipse and Tomcat are mismatched ..either change eclipse one to tomcat one or ViceVersa..

Both should be same ..Java version mismatched ..Check it

If it is a local file, you have to wrap it in htmlspecialchars like so:

    $myfile = htmlspecialchars(file_get_contents($file_name));

Then it works

Another example which uses function in ref rather than string

class List extends React.Component {
  constructor(props) {
    super(props);
    this.state = { items:[], index: 0 };
    this._nodes = new Map();

    this.handleAdd = this.handleAdd.bind(this);
    this.handleRemove = this.handleRemove.bind(this);
   }

  handleAdd() {
    let startNumber = 0;
    if (this.state.items.length) {
      startNumber = this.state.items[this.state.items.length - 1];
    }

    let newItems = this.state.items.splice(0);
    for (let i = startNumber; i < startNumber + 100; i++) {
      newItems.push(i);
    }

    this.setState({ items: newItems });
  }

  handleRemove() {
    this.setState({ items: this.state.items.slice(1) });
  }

  handleShow(i) {
    this.setState({index: i});
    const node = this._nodes.get(i);
    console.log(this._nodes);
    if (node) {
      ReactDOM.findDOMNode(node).scrollIntoView({block: 'end', behavior: 'smooth'});
    }
  }

  render() {
    return(
      <div>
        <ul>{this.state.items.map((item, i) => (<Item key={i} ref={(element) => this._nodes.set(i, element)}>{item}</Item>))}</ul>
        <button onClick={this.handleShow.bind(this, 0)}>0</button>
        <button onClick={this.handleShow.bind(this, 50)}>50</button>
        <button onClick={this.handleShow.bind(this, 99)}>99</button>
        <button onClick={this.handleAdd}>Add</button>
        <button onClick={this.handleRemove}>Remove</button>
        {this.state.index}
      </div>
    );
  }
}

class Item extends React.Component
{
  render() {
    return (<li ref={ element => this.listItem = element }>
      {this.props.children}
    </li>);
  }
}

The following is a more efficient answer to the question rather than hard-coding the style.

To change the day to ordinal number you need to use the following suffix.

DD +     TH = DDTH  result >>>> 4TH

OR to spell the number add SP to the format

DD + SPTH = DDSPTH   result >>> FOURTH

For PHP, put this line of code before you start printing your XML:

while(ob_get_level()) ob_end_clean();

TortoiseGit (Windows)

For anyone using TortoiseGit for Windows, I did this:

(1) Right-click on the folder containing your project. Select TortoiseGit -> Settings.

(2) On the "Git" tab, click the button to "Edit local .git/config".

(3) In the text file that pops up, under the [core] section, add: longpaths = true

Save and close everything, then re-try your commit. For me, this worked.

I hope this minimizes any possible system-wide issues, since we are not editing the global .gitconfig file, but rather just the one for this particular repository.

Related with the answer by @DanielSerrano, I've been recently bit by localization of the sc.exe command, namely in Spanish. My proposal is to pin-point the line and token which holds numerical service state and interpret it, which should be much more robust:

@echo off

rem TODO: change to the desired service name
set TARGET_SERVICE=w32time

set SERVICE_STATE=
rem Surgically target third line, as some locales (such as Spanish) translated the utility's output
for /F "skip=3 tokens=3" %%i in ('""%windir%\system32\sc.exe" query "%TARGET_SERVICE%" 2>nul"') do (
  if not defined SERVICE_STATE set SERVICE_STATE=%%i
)
rem Process result
if not defined SERVICE_STATE (
  echo ERROR: could not obtain service state!
) else (
  rem NOTE: values correspond to "SERVICE_STATUS.dwCurrentState"
  rem https://msdn.microsoft.com/en-us/library/windows/desktop/ms685996(v=vs.85).aspx
  if not %SERVICE_STATE%==4 (
    echo WARNING: service is not running
    rem TODO: perform desired operation
    rem net start "%TARGET_SERVICE%"
  ) else (
    echo INFORMATION: service is running
  )
)

Tested with:

• Windows XP (32-bit) English
• Windows 10 (32-bit) Spanish
• Windows 10 (64-bit) English

Why not JSON.stringify and .includes()?

You can easily check if a JSON object includes a value by turning it into a string and checking the string.

console.log(JSON.stringify(JSONObject).includes("dog"))
--> true

Edit: make sure to check browser compatibility for .includes()

I couldn't get Facebook to pick the right image from a specific post, so I did what's outlined on this page:

https://webapps.stackexchange.com/questions/18468/adding-meta-tags-to-individual-blogger-posts

In other words, something like this:

<b:if cond='data:blog.url == "http://urlofyourpost.com"'>
  <meta content='http://urlofyourimage.png' property='og:image'/>
 </b:if>

Basically, you're going to hard code an if statement into your site's HTML to get it to change the meta content for whatever you've changed for that one post. It's a messy solution, but it works.

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

If you want to do it by ClassName you could do:

<script type="text/javascript">
function hideTd(className){
    var elements;

    if (document.getElementsByClassName)
    {
        elements = document.getElementsByClassName(className);
    }
    else
    {
        var elArray = [];
        var tmp = document.getElementsByTagName(elements);  
        var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
        for ( var i = 0; i < tmp.length; i++ ) {

            if ( regex.test(tmp[i].className) ) {
                elArray.push(tmp[i]);
            }
        }

        elements = elArray;
    }

    for(var i = 0, i < elements.length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>

I solved the similar situation with basic technique using pandas. First load the csv or text file using pandas.It's pretty simple

data=pd.read_excel('link to the file')

Then set the index of data to the respected column that needs to be changed. For example, if your data has ID as one attribute or column, then set index to ID.

 data = data.set_index("ID")

Then delete all the rows with "id" as the value instead of number using following command.

  data = data.drop("id", axis=0). 

Hope, this will help you.

REST is somewhat of a revival of old-school HTTP, where the actual HTTP verbs (commands) have semantic meaning. Til recently, apps that wanted to update stuff on the server would supply a form containing an 'action' variable and a bunch of data. The HTTP command would almost always be GET or POST, and would be almost irrelevant. (Though there's almost always been a proscription against using GET for operations that have side effects, in reality a lot of apps don't care about the command used.)

With REST, you might instead PUT /profiles/cHao and send an XML or JSON representation of the profile info. (Or rather, I would -- you would have to update your own profile. :) That'd involve logging in, usually through HTTP's built-in authentication mechanisms.) In the latter case, what you want to do is specified by the URL, and the request body is just the guts of the resource involved.

http://en.wikipedia.org/wiki/Representational_State_Transfer has some details.

I've been using Nuitka and PyInstaller with my package, PySimpleGUI.

Nuitka There were issues getting tkinter to compile with Nuikta. One of the project contributors developed a script that fixed the problem.

If you're not using tkinter it may "just work" for you. If you are using tkinter say so and I'll try to get the script and instructions published.

PyInstaller I'm running 3.6 and PyInstaller is working great! The command I use to create my exe file is:

pyinstaller -wF myfile.py

The -wF will create a single EXE file. Because all of my programs have a GUI and I do not want to command window to show, the -w option will hide the command window.

This is as close to getting what looks like a Winforms program to run that was written in Python.

[Update 20-Jul-2019]

There is PySimpleGUI GUI based solution that uses PyInstaller. It uses PySimpleGUI. It's called pysimplegui-exemaker and can be pip installed.

pip install PySimpleGUI-exemaker

To run it after installing:

python -m pysimplegui-exemaker.pysimplegui-exemaker

jquery will provide you with this and more ...

if($("#something").val()){ //do stuff}

It took me a couple of days to pick it up, but it provides you with you with so much more functionality. An example below.

jQuery(document).ready(function() {
    /* finds closest element with class divright/left and 
    makes all checkboxs inside that div class the same as selectAll...
    */
        $("#selectAll").click(function() {
        $(this).closest('.divright').find(':checkbox').attr('checked', this.checked);
    });
});

If you're using Java 9, there's an easy way with less number of lines without needing to initialize or add method.

List<String> list = List.of("first", "second", "third");

Can't you just create a static method that does exactly this?

private static <K, V> V getOrDefault(Map<K,V> map, K key, V defaultValue) {
    return map.containsKey(key) ? map.get(key) : defaultValue;
}

If You Use Namespaces

In my own findings, I think it's good to mention that you (as far as I can tell) must declare the full namespace path of a class.

MyClass.php

namespace com\company\lib;
class MyClass {
}

index.php

namespace com\company\lib;

//Works fine
$i = new MyClass();

$cname = 'MyClass';

//Errors
//$i = new $cname;

//Works fine
$cname = "com\\company\\lib\\".$cname;
$i = new $cname;

Command Line option - Ubuntu

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

Then in terminal

sudo apt-get install oracle-java8-installer

When there are multiple Java installations on your System, the Java version to use as default can be chosen. To do this, execute the following command.

sudo update-alternatives --config java
sudo update-alternatives --config javac
sudo update-alternatives --config javaws

Edit - Manual Java Installation

Download oracle jdk

The easiest way is to use position: fixed:

.element {
  position: fixed;
  bottom: 0;
  right: 0;
}

http://www.w3.org/TR/CSS21/visuren.html#choose-position

(note that position fixed is buggy / doesn't work on ios and android browsers)

I wrote this extension method based off @Lee's response to the OP. Note, a default parameter was used (requiring C# 4.0). However, an overloaded method call in C# 3.0 would suffice.

/// <summary>
/// Method that returns all the duplicates (distinct) in the collection.
/// </summary>
/// <typeparam name="T">The type of the collection.</typeparam>
/// <param name="source">The source collection to detect for duplicates</param>
/// <param name="distinct">Specify <b>true</b> to only return distinct elements.</param>
/// <returns>A distinct list of duplicates found in the source collection.</returns>
/// <remarks>This is an extension method to IEnumerable&lt;T&gt;</remarks>
public static IEnumerable<T> Duplicates<T>
         (this IEnumerable<T> source, bool distinct = true)
{
     if (source == null)
     {
        throw new ArgumentNullException("source");
     }

     // select the elements that are repeated
     IEnumerable<T> result = source.GroupBy(a => a).SelectMany(a => a.Skip(1));

     // distinct?
     if (distinct == true)
     {
        // deferred execution helps us here
        result = result.Distinct();
     }

     return result;
}

Place the function value into the cell

Application.Sum often does not work well in my experience (or at least the VBA developer environment does not like it for whatever reason).

The function that works best for me is Excel.WorksheetFunction.Sum()

Example:

Dim Report As Worksheet 'Set up your new worksheet variable.
Set Report = Excel.ActiveSheet 'Assign the active sheet to the variable.

Report.Cells(11, 1).Value = Excel.WorksheetFunction.Sum(Report.Range("A1:A10")) 'Add the function result.

Place the function directly into the cell

The other method which you were looking for I think is to place the function directly into the cell. This can be done by inputting the function string into the cell value. Here is an example that provides the same result as above, except the cell value is given the function and not the result of the function:

    Dim Report As Worksheet 'Set up your new worksheet variable.
    Set Report = Excel.ActiveSheet 'Assign the active sheet to the variable.

    Report.Cells(11, 1).Value = "=Sum(A1:A10)" 'Add the function.

History.

The earliest versions of Unix time had a 32-bit integer incrementing at a rate of 60 Hz, which was the rate of the system clock on the hardware of the early Unix systems. The value 60 Hz still appears in some software interfaces as a result. The epoch also differed from the current value. The first edition Unix Programmer's Manual dated November 3, 1971 defines the Unix time as "the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second".

I would go with Larry K's solution, but you can also set the display to inline-block if you want the benefits of both block and inline elements.

You can do this in the div tag by inserting:

style="display:inline-block;"

Or in a CSS stylesheet with this method:

div { display:inline-block; }

Hope it helps, but as earlier mentioned, I would personally go for Larry K's solution ;-)

The main difference between Abstract Factory and Factory Method is that Abstract Factory is implemented by Composition; but Factory Method is implemented by Inheritance.

Yes, you read that correctly: the main difference between these two patterns is the old composition vs inheritance debate.

UML diagrams can be found in the (GoF) book. I want to provide code examples, because I think combining the examples from the top two answers in this thread will give a better demonstration than either answer alone. Additionally, I have used terminology from the book in class and method names.

Abstract Factory

1. The most important point to grasp here is that the abstract factory is injected into the client. This is why we say that Abstract Factory is implemented by Composition. Often, a dependency injection framework would perform that task; but a framework is not required for DI.
2. The second critical point is that the concrete factories here are not Factory Method implementations! Example code for Factory Method is shown further below.
3. And finally, the third point to note is the relationship between the products: in this case the outbound and reply queues. One concrete factory produces Azure queues, the other MSMQ. The GoF refers to this product relationship as a "family" and it's important to be aware that family in this case does not mean class hierarchy.

public class Client {
    private final AbstractFactory_MessageQueue factory;

    public Client(AbstractFactory_MessageQueue factory) {
        // The factory creates message queues either for Azure or MSMQ.
        // The client does not know which technology is used.
        this.factory = factory;
    }

    public void sendMessage() {
        //The client doesn't know whether the OutboundQueue is Azure or MSMQ.
        OutboundQueue out = factory.createProductA();
        out.sendMessage("Hello Abstract Factory!");
    }

    public String receiveMessage() {
        //The client doesn't know whether the ReplyQueue is Azure or MSMQ.
        ReplyQueue in = factory.createProductB();
        return in.receiveMessage();
    }
}

public interface AbstractFactory_MessageQueue {
    OutboundQueue createProductA();
    ReplyQueue createProductB();
}

public class ConcreteFactory_Azure implements AbstractFactory_MessageQueue {
    @Override
    public OutboundQueue createProductA() {
        return new AzureMessageQueue();
    }

    @Override
    public ReplyQueue createProductB() {
        return new AzureResponseMessageQueue();
    }
}

public class ConcreteFactory_Msmq implements AbstractFactory_MessageQueue {
    @Override
    public OutboundQueue createProductA() {
        return new MsmqMessageQueue();
    }

    @Override
    public ReplyQueue createProductB() {
        return new MsmqResponseMessageQueue();
    }
}

Factory Method

1. The most important point to grasp here is that the ConcreteCreator is the client. In other words, the client is a subclass whose parent defines the factoryMethod(). This is why we say that Factory Method is implemented by Inheritance.
2. The second critical point is to remember that the Factory Method Pattern is nothing more than a specialization of the Template Method Pattern. The two patterns share an identical structure. They only differ in purpose. Factory Method is creational (it builds something) whereas Template Method is behavioral (it computes something).
3. And finally, the third point to note is that the Creator (parent) class invokes its own factoryMethod(). If we remove anOperation() from the parent class, leaving only a single method behind, it is no longer the Factory Method pattern. In other words, Factory Method cannot be implemented with less than two methods in the parent class; and one must invoke the other.

public abstract class Creator {
    public void anOperation() {
        Product p = factoryMethod();
        p.whatever();
    }

    protected abstract Product factoryMethod();
}

public class ConcreteCreator extends Creator {
    @Override
    protected Product factoryMethod() {
        return new ConcreteProduct();
    }
}

Misc. & Sundry Factory Patterns

Be aware that although the GoF define two different Factory patterns, these are not the only Factory patterns in existence. They are not even necessarily the most commonly used Factory patterns. A famous third example is Josh Bloch's Static Factory Pattern from Effective Java. The Head First Design Patterns book includes yet another pattern they call Simple Factory.

Don't fall into the trap of assuming every Factory pattern must match one from the GoF.

Is this what you're after?

http://jsfiddle.net/dCNXU/1/

I added :text-align:center to the div and image

That is a problem of security protocol. I am using TLSv1 but the host accept only TLSv1.1 and TLSv1.2 then I changed the protocol in Java with the instruction below:

System.setProperty("https.protocols", "TLSv1.1");

Data validation drop down

There is a list option in Data validation. If this is combined with a VLOOKUP formula you would be able to convert the selected value into a number.

The steps in Excel 2010 are:

• Create your list with matching values.
• On the Data tab choose Data Validation
• The Data validation form will be displayed
• Set the Allow dropdown to List
• Set the Source range to the first part of your list
• Click on OK (User messages can be added if required)

In a cell enter a formula like this

=VLOOKUP(A2,$D$3:$E$5,2,FALSE)

which will return the matching value from the second part of your list.

Form control drop down

Alternatively, Form controls can be placed on a worksheet. They can be linked to a range and return the position number of the selected value to a specific cell.

The steps in Excel 2010 are:

• Create your list of data in a worksheet
• Click on the Developer tab and dropdown on the Insert option
• In the Form section choose Combo box or List box
• Use the mouse to draw the box on the worksheet
• Right click on the box and select Format control
• The Format control form will be displayed
• Click on the Control tab
• Set the Input range to your list of data
• Set the Cell link range to the cell where you want the number of the selected item to appear
• Click on OK

I've located a solution that worked better for me, and which has the advantage of being usable with several images (case not illustrated in this example).

From @adeneo's answer on this question :

If you have an element with a background image, like this

<div id="test" style="background-image: url(link/to/image.png)"><div>

You can wait for the background to load by getting the image URL and using it for an image object in javascript with an onload handler

var src = $('#test').css('background-image');
var url = src.match(/\((.*?)\)/)[1].replace(/('|")/g,'');

var img = new Image();
img.onload = function() {
    alert('image loaded');
}
img.src = url;
if (img.complete) img.onload();

You can actually do what Chris Chalmers does in his answer, but you must make sure that HAML doesn't parse the JavaScript. This approach is actually useful when you need to use a different type than text/javascript, which is was I needed to do for MathJax.

You can use the plain filter to keep HAML from parsing the script and throwing an illegal nesting error:

%script{type: "text/x-mathjax-config"}
  :plain
    MathJax.Hub.Config({
      tex2jax: {
        inlineMath: [["$","$"],["\\(","\\)"]]
      }
    });

title is a local variable. They only exists within its scope (current block)

@title is an instance variable - and is available to all methods within the class.

You can read more here: http://strugglingwithruby.blogspot.dk/2010/03/variables.html

In Ruby on Rails - declaring your variables in your controller as instance variables (@title) makes them available to your view.

One more way- By using java.lang.Integer you can get string representation of the first argument i in the radix (Octal - 8, Hex - 16, Binary - 2) specified by the second argument.

 Integer.toString(i, radix)

Example_

private void getStrtingRadix() {
        // TODO Auto-generated method stub
         /* returns the string representation of the 
          unsigned integer in concern radix*/
         System.out.println("Binary eqivalent of 100 = " + Integer.toString(100, 2));
         System.out.println("Octal eqivalent of 100 = " + Integer.toString(100, 8));
         System.out.println("Decimal eqivalent of 100 = " + Integer.toString(100, 10));
         System.out.println("Hexadecimal eqivalent of 100 = " + Integer.toString(100, 16));
    }

OutPut_

Binary eqivalent of 100 = 1100100
Octal eqivalent of 100 = 144
Decimal eqivalent of 100 = 100
Hexadecimal eqivalent of 100 = 64

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

try something like :

var focusout = false;

$("#Button1").click(function () {
    if (focusout == true) {
        focusout = false;
        return;
    }
    else {
        GetInfo();
    }
});

$("#Text1").focusout(function () {
    focusout = true;
    GetInfo();
});

The above method works good.

Another method (I am assuming web here) is to create your page. Add controls to the page. Then while in design mode go to: Tools > Generate Local Resource. A resource file will automatically appear in the solution with all the controls in the page mapped in the resource file.

To create resources for other languages, append the 4 character language to the end of the file name, before the extension (Account.aspx.en-US.resx, Account.aspx.es-ES.resx...etc).

To retrieve specific entries in the code-behind, simply call this method: GetLocalResourceObject([resource entry key/name]).

DIY cw.exe (console write) utility

If you don't find it out-of-the-box, off-the-shelf, you can DIY. With this cw utility you can use every kind of characters. At least, I'd like to think so. Please stress-test it and let me know.

Tools

All you need is .NET installed, which is very common nowadays.

Materials

Some characters typed/copy-pasted.

Steps

1. Create .bat file with the following content.

/* >nul 2>&1

@echo off
setlocal

set exe=cw
for /f "tokens=* delims=" %%v in ('dir /b /s /a:-d  /o:-n "%SystemRoot%\Microsoft.NET\Framework\*csc.exe"') do set "csc=%%v"

"%csc%" -nologo -out:"%exe%.exe" "%~f0"

endlocal
exit /b %errorlevel%

*/

using System;

namespace cw {
    class Program {
        static void Main() {
            var exe = Environment.GetCommandLineArgs()[0];
            var rawCmd = Environment.CommandLine;
            var line = rawCmd.Remove(rawCmd.IndexOf(exe),exe.Length).TrimStart('"');
            line = line.Length < 2 ? "\r" : line.Substring(2) ;
            Console.Write(line);
        }
    }
}

2. Run it.

3. Now you have a nice 4KB utility so you can delete the .bat.

Alternatively, you can insert this code as a subroutine in any batch, send the resulting .exe to %temp%, use it in your batch and delete it when you're done.

How to use

If you want write something without new line:
cw Whatever you want, even with "", but remember to escape ^|, ^^, ^&, etc. unless double-quoted, like in "| ^ &".

If you want a carriage return (going to the beginning of the line), run just
cw

So try this from command line:

for /l %a in (1,1,1000) do @(cw ^|&cw&cw /&cw&cw -&cw&cw \&cw)

bmleite has the correct answer about including the module.

If that is correct in your situation, you should also ensure that you are not redefining the modules in multiple files.

Remember:

angular.module('ModuleName', [])   // creates a module.

angular.module('ModuleName')       // gets you a pre-existing module.

So if you are extending a existing module, remember not to overwrite when trying to fetch it.

Check out this link: http://www.switchonthecode.com/tutorials/csharp-tutorial-image-editing-saving-cropping-and-resizing

   return bmpImage.Clone(cropArea, bmpImage.PixelFormat);
}

It looks that 3.15 offers no satisfying solution: either one uses the old style with Cell.CELL_TYPE_*, or we use the method getCellTypeEnum() which is marked as deprecated. A lot of disturbances for little add value...

I believe you're looking for...

import config.logging_settings  # @UnusedImport

Note the double space before the comment to avoid hitting other formatting warnings.

Also, depending on your IDE (if you're using one), there's probably an option to add the correct ignore rule (e.g., in Eclipse, pressing Ctrl + 1, while the cursor is over the warning, will auto-suggest @UnusedImport).

There is no => for if.
Use if %energy% GEQ %m2enc%

See if /? for some other details.

You can try this:

:backup move C:\FilesToBeBackedUp\*.* E:\BackupPlace\ timeout 36000 goto backup

If that doesn't work try to replace "timeout" with sleep. Ik this post is over a year old, just helping anyone with the same problem.

You can check your eav_attributes table to find the relevant attribute IDs for each image role, such as;

Then you can use those to set whichever role to any other role for all products like so;

UPDATE catalog_product_entity_varchar AS `v` INNER JOIN (SELECT `value`,`entity_id` FROM `catalog_product_entity_varchar` WHERE `attribute_id`=86) AS `j` ON `j`.`entity_id`=`v`.entity_id SET `v`.`value`=j.`value` WHERE `v`.attribute_id = 85 AND `v`.`entity_id`=`j`.`entity_id`

The above will set all your 'base' roles to the 'small' image of the same product.

Had the same error when I had @Order annotation on a filter class. Even thou I added the filter through the HttpSecurity chain.

Removed the @Order and it worked.

You have to run the $ php artisan migrate command from within Homestead, not your Mac.

Waking up a dead question here but the answers provided will not work with jdk 7 (I read somewhere that a bug is open for this for Oracle Engineers but not fixed yet). Along with the link that @Ryan provided, you will have to also add :

System.setProperty("jsse.enableSNIExtension", "false");

(Courtesy to many stackoverflow answers combined together to figure this out)

Check out the request module.

It's more full featured than node's built-in http client.

var request = require('request');

var propertiesObject = { field1:'test1', field2:'test2' };

request({url:url, qs:propertiesObject}, function(err, response, body) {
  if(err) { console.log(err); return; }
  console.log("Get response: " + response.statusCode);
});

Anyone tried this approach?

Doing a dir /s vs_ultimate.exe from the root prompt will find it. Mine was in <C:\ProgramData\Package Cache\{[guid]}>. Once I navigated there and ran vs_community_ENU.exe /uninstall /force it uninstalled all the Visual Studio assets I believe.

Got the advice from this post.

You are modifying the list book_shop.values()[i], which is not getting updated in the dictionary. Whenever you call the values() method, it will give you the values available in dictionary, and here you are not modifying the data of the dictionary.

If it's a maven project, go to file>import>maven project >existing maven project, then browse for the folder that contains the project, select folder then click finish. That worked for me

For Ionic (Typescript) you have to double slash in order to scape the characters. For example (this is to match some special characters):

"^(?=.*[\\]\\[!¡\'=ªº\\-\\_ç@#$%^&*(),;\\.?\":{}|<>\+\\/])"

Pay attention to this ] [ - _ . / characters. They have to be double slashed. If you don't do that, you are going to have a type error in your code.

Simplest way I could think of: add a class.

Simply add a class (on any element) and check inside the interval if it's there. This is more reliable, customisable and cross-language than any other way, I believe.

var i = 0;_x000D_
this.setInterval(function() {_x000D_
  if(!$('#counter').hasClass('pauseInterval')) { //only run if it hasn't got this class 'pauseInterval'_x000D_
    console.log('Counting...');_x000D_
    $('#counter').html(i++); //just for explaining and showing_x000D_
  } else {_x000D_
    console.log('Stopped counting');_x000D_
  }_x000D_
}, 500);_x000D_
_x000D_
/* In this example, I'm adding a class on mouseover and remove it again on mouseleave. You can of course do pretty much whatever you like */_x000D_
$('#counter').hover(function() { //mouse enter_x000D_
    $(this).addClass('pauseInterval');_x000D_
  },function() { //mouse leave_x000D_
    $(this).removeClass('pauseInterval');_x000D_
  }_x000D_
);_x000D_
_x000D_
/* Other example */_x000D_
$('#pauseInterval').click(function() {_x000D_
  $('#counter').toggleClass('pauseInterval');_x000D_
});

body {_x000D_
  background-color: #eee;_x000D_
  font-family: Calibri, Arial, sans-serif;_x000D_
}_x000D_
#counter {_x000D_
  width: 50%;_x000D_
  background: #ddd;_x000D_
  border: 2px solid #009afd;_x000D_
  border-radius: 5px;_x000D_

  text-align: center;_x000D_

  margin: 0 auto;_x000D_
}_x000D_
#counter.pauseInterval {_x000D_
  border-color: red;  _x000D_
}

<!-- you'll need jQuery for this. If you really want a vanilla version, ask -->_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

<button id="pauseInterval">Pause/unpause</button></p>

using $(this) improves performance, as the class/whatever attr u are using to search, need not be searched for multiple times in the entire webpage content.

You can also do like this:

template <typename T>
class make_vector {
public:
  typedef make_vector<T> my_type;
  my_type& operator<< (const T& val) {
    data_.push_back(val);
    return *this;
  }
  operator std::vector<T>() const {
    return data_;
  }
private:
  std::vector<T> data_;
};

And use it like this:

std::vector<int> v = make_vector<int>() << 1 << 2 << 3;

string foo = "Apple, Plum, Cherry";

string[] myArr = null;

myArr = foo.Split(',');

If your html is similar to the example, so the click event is produced over the label, not in the input, so I use the next code: Html example:

<div id="myButtons" class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
  </label>      
</div>

Javascript code for the event:

$('#option1').parent().on("click", function () {
   alert("click fired"); 
});

It's been the third time that I install Windows and npp and after some time I realize the tidy function no longer work. So I google for a solution, come to this thread, then with the help of few more so threads I finally fix it. I'll put a summary of all my actions once and for all.

1. Install TextFX plugin: Plugins -> Plugin Manager -> Show Plugin Manager. Select TextFX Characters and install. After a restart of npp, the menu 'TextFX' should be visible. (credits: @remipod).

2. Install libtidy.dll by pasting the Config folder from an old npp package: Follow instructions in this answer.

3. After having a Config folder in your latest npp installation destination (typically C:\Program Files (x86)\Notepad++\plugins), npp needs write access to that folder. Right click Config folder -> Properties -> Security tab -> select Users, click Edit -> check Full control to allow read/write access. Note that you need administrator privileges to do that.

4. Restart npp and verify TextFX -> TextFX HTML Tidy -> Tidy: Reindent XML works.

Besides what @khmarbaise has pointed out, I think you have mistyped your JAVA_HOME. If you have installed in the default location, then there should be no "-" (hyphen) between jdk and 1.7.0_04. So it would be

JAVA_HOME C:\Program Files\Java\jdk1.7.0_04 

I had a further issue that foxed me for a while when theming existing code from a CMS. I wanted to use flexbox with justify-content:space-between but the left and right elements weren't flush.

In that system the items were floated and the container had a :before and/or an :after to clear floats at beginning or end. So setting those sneaky :before and :after elements to display:none did the trick.

It depends. The System.Timers.Timer has two modes of operation.

If SynchronizingObject is set to an ISynchronizeInvoke instance then the Elapsed event will execute on the thread hosting the synchronizing object. Usually these ISynchronizeInvoke instances are none other than plain old Control and Form instances that we are all familiar with. So in that case the Elapsed event is invoked on the UI thread and it behaves similar to the System.Windows.Forms.Timer. Otherwise, it really depends on the specific ISynchronizeInvoke instance that was used.

If SynchronizingObject is null then the Elapsed event is invoked on a ThreadPool thread and it behaves similar to the System.Threading.Timer. In fact, it actually uses a System.Threading.Timer behind the scenes and does the marshaling operation after it receives the timer callback if needed.

It is a defect of Selenium.
I have the same problem in Ubuntu 12.04 behind the proxy.

Problem is in incorrect processing proxy exclusions. Default Ubuntu exclusions are located in no_proxy environment variable:

no_proxy=localhost,127.0.0.0/8

But it seems that /8 mask doesn't work for selenium. To workaround the problem it is enough to change no_proxy to the following:

no_proxy=localhost,127.0.0.1

Removing proxy settings before running python script also helps:

http_proxy= python script.py

There are Registry changes you can make to explicitly select where the crash dump file resides, otherwise %localappdata%\Microsoft\Windows\WER is the default location. I assume that %localappdata% is defined differently for a user or a service running under System. You will need to enable WER I believe.

To answer the underlying question of how to use a CASE expression in the WHERE clause:

First remember that the value of a CASE expression has to have a normal data type value, not a boolean value. It has to be a varchar, or an int, or something. It's the same reason you can't say SELECT Name, 76 = Age FROM [...] and expect to get 'Frank', FALSE in the result set.

Additionally, all expressions in a WHERE clause need to have a boolean value. They can't have a value of a varchar or an int. You can't say WHERE Name; or WHERE 'Frank';. You have to use a comparison operator to make it a boolean expression, so WHERE Name = 'Frank';

That means that the CASE expression must be on one side of a boolean expression. You have to compare the CASE expression to something. It can't stand by itself!

Here:

WHERE 
    DateDropped = 0
    AND CASE
            WHEN @JobsOnHold  = 1 AND DateAppr >= 0 THEN 'True'
            WHEN DateAppr != 0 THEN 'True'
            ELSE 'False'
        END = 'True'

Notice how in the end the CASE expression on the left will turn the boolean expression into either 'True' = 'True' or 'False' = 'True'.

Note that there's nothing special about 'False' and 'True'. You can use 0 and 1 if you'd rather, too.

You can typically rewrite the CASE expression into boolean expressions we're more familiar with, and that's generally better for performance. However, sometimes is easier or more maintainable to use an existing expression than it is to convert the logic.

The command within the Sqlite shell to open a database is .open

The syntax is,

sqlite> .open dbasename.db

If it is a new database that you would like to create and open, it is

sqlite> .open --new dbasename.db

If the database is existing in a different folder, the path has to be mentioned like this:

sqlite> .open D:/MainFolder/SubFolder/...database.db

In Windows Command shell, you should use '\' to represent a directory, but in SQLite directories are represented by '/'. If you still prefer to use the Windows notation, you should use an escape sequence for every '\'

Use COPY table TO ... WITH BINARY which is according to the documentation is "somewhat faster than the text and CSV formats." Only do this if you have millions of rows to insert, and if you are comfortable with binary data.

Here is an example recipe in Python, using psycopg2 with binary input.

I think I found what you are looking for since I was also looking for it.

You have to follow Pawel's steps and then go to the key that is "Cookie". This will open a submenu with all the cookies and it specifies their name, value, domain, etc...

Respectively the values are: Key, Value, Expiration Date, Domain, Path.

This shows all the keys for this domain.

So again to get there:

1. Go to Network.
2. Capture Traffic, green triangle.
3. Go to Details.
4. Go to the "Cookie" key that has a gibberish value. (_utmc=xxxxx;something=ajksdhfa) etc...

Close Your Xcode , close any git client(source tree or terminal)if it is opened and finally restart your project.

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

You can create dispatch queue using this code in swift 3.0

DispatchQueue.main.async
 {
   /*Write your code here*/
 }

   /* or */

let delayTime = DispatchTime.now() + Double(Int64(0.5 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)                   
DispatchQueue.main.asyncAfter(deadline: delayTime)
{
  /*Write your code here*/
}

def on_message(ws, message):
    print message

def on_error(ws, error):
    print error

def on_close(ws):

            time.sleep(1)
            ws.send("Hello %d" % i)
        time.sleep(1)
        ws.close()

1. No you don’t need quotes.

2. Yes you can. But note that relative URLs are resolved from the URL of your stylesheet.

3. Better don’t use quotes. I think there are clients that don’t understand them.

Neither of the suggested solutions worked for me. So I kept on searching for an alternative solution, which ended up being a mixture of the two before mentioned and a third step.

1. set the indent-number into the transformerfactory
2. enable the indent in the transformer
3. wrap the otuputstream with a writer (or bufferedwriter)

//(1)
TransformerFactory tf = TransformerFactory.newInstance();
tf.setAttribute("indent-number", new Integer(2));

//(2)
Transformer t = tf.newTransformer();
t.setOutputProperty(OutputKeys.INDENT, "yes");

//(3)
t.transform(new DOMSource(doc),
new StreamResult(new OutputStreamWriter(out, "utf-8"));

You must do (3) to workaround a "buggy" behavior of the xml handling code.

hash_items = {:item => 1}
puts hash_items 
#hash_items will give you {:item => 1}

hash_items.merge!({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}

hash_items.merge({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}, but the original variable will be the same old one.

I have do something like this to get date in local device timezone from UTC time stamp.

private long UTC_TIMEZONE=1470960000;
private String OUTPUT_DATE_FORMATE="dd-MM-yyyy - hh:mm a"

getDateFromUTCTimestamp(UTC_TIMEZONE,OUTPUT_DATE_FORMATE);

Here is the function

 public String getDateFromUTCTimestamp(long mTimestamp, String mDateFormate) {
        String date = null;
        try {
            Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
            cal.setTimeInMillis(mTimestamp * 1000L);
            date = DateFormat.format(mDateFormate, cal.getTimeInMillis()).toString();

            SimpleDateFormat formatter = new SimpleDateFormat(mDateFormate);
            formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
            Date value = formatter.parse(date);

            SimpleDateFormat dateFormatter = new SimpleDateFormat(mDateFormate);
            dateFormatter.setTimeZone(TimeZone.getDefault());
            date = dateFormatter.format(value);
            return date;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return date;
    }

Result :

Hope this will work for others.

    $ 150.00
    Fr. 150.00
    € 689.00

I have tested for above three currency symbols .You can do it for others also.

    var price = Fr. 150.00;
    var priceFloat = price.replace(/[^\d\.]/g, '');

Above regular expression will remove everything that is not a digit or a period.So You can get the string without currency symbol but in case of " Fr. 150.00 " if you console for output then you will get price as

    console.log('priceFloat : '+priceFloat);

    output will be like  priceFloat : .150.00

which is wrong so you check the index of "." then split that and get the proper result.

    if (priceFloat.indexOf('.') == 0) {
            priceFloat = parseFloat(priceFloat.split('.')[1]);
    }else{
            priceFloat = parseFloat(priceFloat);
    }

Since this still comes up as a first answer in Google I'll contribute possible solution.

Command taken from here suprisingly worked for me (Docker 1.13.1, Ubuntu 16.04) :

docker exec -u 0 <container-name> /bin/sh -c "echo '<ip> <name> >> /etc/hosts"

First off, your trigger as you already see is going to update every record in the table. There is no filtering done to accomplish jus the rows changed.

Secondly, you're assuming that only one row changes in the batch which is incorrect as multiple rows could change.

The way to do this properly is to use the virtual inserted and deleted tables: http://msdn.microsoft.com/en-us/library/ms191300.aspx

Update for CXF 3.1.7

In my case I put the WSDL files in src/main/resources and added this path to my Srouces in Eclipse (Right Click on Project-> Build Path -> Configure Build Path...-> Source[Tab] -> Add Folder).

Here is how my pom file looks like and as can be seen there is NO wsdlLocation option needed:

       <plugin>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-codegen-plugin</artifactId>
            <version>${cxf.version}</version>
            <executions>
                <execution>
                    <id>generate-sources</id>
                    <phase>generate-sources</phase>
                    <configuration>
                        <sourceRoot>${project.build.directory}/generated/cxf</sourceRoot>
                        <wsdlOptions>
                            <wsdlOption>
                                <wsdl>classpath:wsdl/FOO_SERVICE.wsdl</wsdl>
                            </wsdlOption>
                        </wsdlOptions>
                    </configuration>
                    <goals>
                        <goal>wsdl2java</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

And here is the generated Service. As can be seen the URL is get from ClassLoader and not from the Absolute File-Path

@WebServiceClient(name = "EventService", 
              wsdlLocation = "classpath:wsdl/FOO_SERVICE.wsdl",
              targetNamespace = "http://www.sas.com/xml/schema/sas-svcs/rtdm-1.1/wsdl/")

I don't have much experience with Flexbox but it seems to me that the forced height on the html and body tags cause the text to disappear on top when resized-- I wasn't able to test in IE but I found the same effect in Chrome.

I forked your fiddle and removed the height and width declarations.

body
{
    margin: 0;
}

It also seemed like the flex settings must be applied to other flex elements. However, applying display: flex to the .inner caused issues so I explicitly set the .inner to display: block and set the .outer to flex for positioning.

I set the minimum .outer height to fill the viewport, the display: flex, and set the horizontal and vertical alignment:

.outer
{
    display:flex;
    min-height: 100%;
    min-height: 100vh;
    align-items: center;
    justify-content: center;
}

I set .inner to display: block explicitly. In Chrome, it looked like it inherited flex from .outer. I also set the width:

.inner
{
    display:block;
    width: 80%;
}

This fixed the issue in Chrome, hopefully it might do the same in IE11. Here's my version of the fiddle: http://jsfiddle.net/ToddT/5CxAy/21/

This should work.

 $foo = someFunction 2>$null

Example from the guide:

\newcommand{\example}[2][YYY]{Mandatory arg: #2;
                                 Optional arg: #1.}

This defines \example to be a command with two arguments, 
referred to as #1 and #2 in the {<definition>}--nothing new so far. 
But by adding a second optional argument to this \newcommand 
(the [YYY]) the first argument (#1) of the newly defined 
command \example is made optional with its default value being YYY.

Thus the usage of \example is either:

   \example{BBB}
which prints:
Mandatory arg: BBB; Optional arg: YYY.
or:
   \example[XXX]{AAA}
which prints:
Mandatory arg: AAA; Optional arg: XXX.

I am not going to give you the whole answer (I don't think you're looking for the parsing and writing to file part anyway), but a pivotal hint should suffice: use python's set() function, and then sorted() or .sort() coupled with .reverse():

>>> a=sorted(set([10,60,30,10,50,20,60,50,60,10,30]))
>>> a
[10, 20, 30, 50, 60]
>>> a.reverse()
>>> a
[60, 50, 30, 20, 10]

Refer django docs on static files.

In settings.py:

import os
CURRENT_PATH = os.path.abspath(os.path.dirname(__file__).decode('utf-8'))

MEDIA_ROOT = os.path.join(CURRENT_PATH, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (
                    os.path.join(CURRENT_PATH, 'static'),
)

Then place your js and css files static folder in your project. Not in media folder.

In views.py:

from django.shortcuts import render_to_response, RequestContext

def view_name(request):
    #your stuff goes here
    return render_to_response('template.html', locals(), context_instance = RequestContext(request))

In template.html:

<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
<script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>

In urls.py:

from django.conf import settings
urlpatterns += patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

You can use the axis() command for that, eg :

x <- 1:100000
y <- 1:100000
marks <- c(0,20000,40000,60000,80000,100000)
plot(x,y,log="x",yaxt="n",type="l")
axis(2,at=marks,labels=marks)

gives :

EDIT : if you want to have all of them in the same format, you can use the solution of @Richie to get them :

x <- 1:100000
y <- 1:100000
format(y,scientific=FALSE)
plot(x,y,log="x",yaxt="n",type="l")
axis(2,at=marks,labels=format(marks,scientific=FALSE))

:not selector:

input:not([type]), input[type='text'], input[type='password'] {
    /* style here */
}

Support: in Internet Explorer 9 and higher

While many options above function well, I found coercion of non-target variables to chr problematic. Using ifelse and grepl within lapply resolves this off-target effect (in limited testing). Using slarky's regular expression in grepl:

set.seed(42)
x1 <- sample(c("a","b"," ", "a a", NA), 10, TRUE)
x2 <- sample(c(rnorm(length(x1),0, 1), NA), length(x1), TRUE)

df <- data.frame(x1, x2, stringsAsFactors = FALSE)

The problem of coercion to character class:

df2 <- lapply(df, function(x) gsub("^$|^ $", NA, x))
lapply(df2, class)

$x1 [1] "character"

$x2 [1] "character"

Resolution with use of ifelse:

df3 <- lapply(df, function(x) ifelse(grepl("^$|^ $", x)==TRUE, NA, x))
lapply(df3, class)

$x1 [1] "character"

$x2 [1] "numeric"

This amazingly worked.

There are a few misunderstandings in the discussion above.

First, you can always ROLLBACK a transaction... no matter what the state of the transaction. So you only have to check the XACT_STATE before a COMMIT, not before a rollback.

As far as the error in the code, you will want to put the transaction inside the TRY. Then in your CATCH, the first thing you should do is the following:

 IF @@TRANCOUNT > 0
      ROLLBACK TRANSACTION @transaction

Then, after the statement above, then you can send an email or whatever is needed. (FYI: If you send the email BEFORE the rollback, then you will definitely get the "cannot... write to log file" error.)

This issue was from last year, so I hope you have resolved this by now :-) Remus pointed you in the right direction.

As a rule of thumb... the TRY will immediately jump to the CATCH when there is an error. Then, when you're in the CATCH, you can use the XACT_STATE to decide whether you can commit. But if you always want to ROLLBACK in the catch, then you don't need to check the state at all.

You can use Type Enforcement accept/returns decorators from PythonDecoratorLibrary It's very easy and readable:

@accepts(int, int, float)
def myfunc(i1, i2, i3):
    pass

There is a way this can be done, but it needs to be planned carefully. Take for example the following QBASIC program:

1 A = 1; B = 10;
10 print "A = ",A;
20 IF (A < B) THEN A = A + 1; GOTO 10
30 PRINT "That's the end."

Then create your JavaScript to initialize all variables first, followed by making an initial function call to start the ball rolling (we execute this initial function call at the end), and set up functions for every set of lines that you know will be executed in the one unit.

Follow this with the initial function call...

var a, b;
function fa(){
    a = 1;
    b = 10;
    fb();
}
function fb(){
    document.write("a = "+ a + "<br>");
    fc();
}
function fc(){
    if(a<b){
        a++;
        fb();
        return;
    }
    else
    {
    document.write("That's the end.<br>");
    }
}
fa();

The result in this instance is:

a = 1
a = 2
a = 3
a = 4
a = 5
a = 6
a = 7
a = 8
a = 9
a = 10
That's the end.

I use below simple solution:

This is your workbook and sheet:

XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("YOUR Workshhet");

then add data to your sheet with columns and rows. Once done with adding data to sheet write following code to autoSizeColumn width.

for (int columnIndex = 0; columnIndex < 15; columnIndex++) {
                    sheet.autoSizeColumn(columnIndex);
                }

Here, instead 15, you add the number of columns in your sheet.

Hope someone helps this.

The only without <input type="file"> is by embedding a transparent flash movie over the div. You can then use a user generated click event (compliant with Flash 10 new security rules) to trigger a call to flash's FileReference.browse.

It offers an added dependency over the quirksmode way but in return you get alot more events (such as built in progress events).

I'm not sure what you want, but i'll use lattice.

x = rep(x,2)
y = c(y1,y2)
fac.data = as.factor(rep(1:2,each=5))
df = data.frame(x=x,y=y,z=fac.data)
# this create a data frame where I have a factor variable, z, that tells me which data I have (y1 or y2)

Then, just plot

xyplot(y ~x|z, df)
# or maybe
xyplot(x ~y|z, df)

For the go up, you just need to use scrollTop instead of scrollBottom:

$("#upClick").on("click", function () {
    scrolled = scrolled - 300;
    $(".cover").stop().animate({
        scrollTop: scrolled
    });
});

Also, use the .stop() method to stop the currently-running animation on the cover div. When .stop() is called on an element, the currently-running animation (if any) is immediately stopped.

FIDDLE DEMO

I'll add one more possible solution, if you're running this on a virtual machine (vmware, etc.) , some other process on the host or other VM could already have the port you're trying to connect with. Either stop that other process or choose another port.
