If you want to maintain order:

arr = arr.reverse().filter(function (e, i, arr) {
    return arr.indexOf(e, i+1) === -1;
}).reverse();

Since there's no built-in reverse indexof, I reverse the array, filter out duplicates, then re-reverse it.

The filter function looks for any occurence of the element after the current index (before in the original array). If one is found, it throws out this element.

Edit:

Alternatively, you could use lastindexOf (if you don't care about order):

arr = arr.filter(function (e, i, arr) {
    return arr.lastIndexOf(e) === i;
});

This will keep unique elements, but only the last occurrence. This means that ['0', '1', '0'] becomes ['1', '0'], not ['0', '1'].

Similar to what @Leonti said, but with a little more depth:

What I did to solve the same problem was open up GIMP, hide all layers except for one, export it as its own image, and then hide that layer and unhide the next one, etc., until I had individual resource files for each one. Then I could use them as frames in the AnimationDrawable XML file.

As a non-java selenium user, here is the python equivalent to Margus's answer:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities    

class ChromeConsoleLogging(object):

    def __init__(self, ):
        self.driver = None

    def setUp(self, ):
        desired = DesiredCapabilities.CHROME
        desired ['loggingPrefs'] = { 'browser':'ALL' }
        self.driver = webdriver.Chrome(desired_capabilities=desired)

    def analyzeLog(self, ):
        data = self.driver.get_log('browser')
        print(data)

    def testMethod(self, ):
        self.setUp()
        self.driver.get("http://mypage.com")
        self.analyzeLog()

Updated Answer (10 Feb 2013)

rmarkdown package: There is now an rmarkdown package available on github that interfaces with Pandoc. It includes a render function. The documentation makes it pretty clear how to convert rmarkdown to pdf among a range of other formats. This includes including output formats in the rmarkdown file or running supplying an output format to the rend function. E.g.,

render("input.Rmd", "pdf_document")

Command-line: When I run render from the command-line (e.g., using a makefile), I sometimes have issues with pandoc not being found. Presumably, it is not on the search path. The following answer explains how to add pandoc to the R environment.

So for example, on my computer running OSX, where I have a copy of pandoc through RStudio, I can use the following:

Rscript -e "Sys.setenv(RSTUDIO_PANDOC='/Applications/RStudio.app/Contents/MacOS/pandoc');library(rmarkdown);  library(utils); render('input.Rmd', 'pdf_document')"

Old Answer (circa 2012)

So, a number of people have suggested that Pandoc is the way to go. See notes below about the importance of having an up-to-date version of Pandoc.

Using Pandoc

I used the following command to convert R Markdown to HTML (i.e., a variant of this makefile), where RMDFILE is the name of the R Markdown file without the .rmd component (it also assumes that the extension is .rmd and not .Rmd).

RMDFILE=example-r-markdown  
Rscript -e "require(knitr); require(markdown); knit('$RMDFILE.rmd', '$RMDFILE.md'); markdownToHTML('$RMDFILE.md', '$RMDFILE.html', options=c('use_xhml'))"

and then this command to convert to pdf

Pandoc -s example-r-markdown.html -o example-r-markdown.pdf

• I removed the reference in the example file which exports plots to imgur to host images.
• I removed a reference to an image that was hosted on imgur. Figures appear to need to be local.
• The options in the markdownToHTML function meant that image references are to files and not to data stored in the HTML file (i.e., I removed 'base64_images' from the option list).
• The resulting output looked like this. It has clearly made a very LaTeX style document in contrast to what I get if I print the HTML file to pdf from a browser.

Getting up-to-date version of Pandoc

As mentioned by @daroczig, it's important to have an up-to-date version of Pandoc in order to output pdfs. On Ubuntu as of 15th June 2012, I was stuck with version 1.8.1 of Pandoc in the package manager, but it seems from the change log that for pdf support you need at least version 1.9+ of Pandoc.

Thus, I installed caball-install. And then ran:

cabal update
cabal install pandoc

Pandoc was installed in ~/.cabal/bin/pandoc Thus, when I ran pandoc it was still seeing the old version. See here for adding to the path.

So many answers and still everybody forgot about the strangely named, oddly behaved, and yet still handy dict.setdefault()

This

value = my_dict.setdefault(key, default)

basically just does this:

try:
    value = my_dict[key]
except KeyError: # key not found
    value = my_dict[key] = default

e.g.

>>> mydict = {'a':1, 'b':2, 'c':3}
>>> mydict.setdefault('d', 4)
4 # returns new value at mydict['d']
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # a new key/value pair was indeed added
# but see what happens when trying it on an existing key...
>>> mydict.setdefault('a', 111)
1 # old value was returned
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # existing key was ignored

Java 6

public boolean moveFile(String sourcePath, String targetPath) {

    File fileToMove = new File(sourcePath);

    return fileToMove.renameTo(new File(targetPath));
}

Java 7 (Using NIO)

public boolean moveFile(String sourcePath, String targetPath) {

    boolean fileMoved = true;

    try {

        Files.move(Paths.get(sourcePath), Paths.get(targetPath), StandardCopyOption.REPLACE_EXISTING);

    } catch (Exception e) {

        fileMoved = false;
        e.printStackTrace();
    }

    return fileMoved;
}

If you are just trying to figure out what a malware does, it might be much easier to run it under something like the free tool Process Monitor which will report whenever it tries to access the filesystem, registry, ports, etc...

Also, using a virtual machine like the free VMWare server is very helpful for this kind of work. You can make a "clean" image, and then just go back to that every time you run the malware.

Public Function WorkSheetExists(ByVal strName As String) As Boolean
   On Error Resume Next
   WorkSheetExists = Not Worksheets(strName) Is Nothing
End Function

sub test_sheet()

 If Not WorkSheetExists("SheetName") Then
 MsgBox "Not available"
Else MsgBox "Available"
End If

End Sub

You can get the full stacktrace:

arguments.callee.caller
arguments.callee.caller.caller
arguments.callee.caller.caller.caller

Until caller is null.

Note: it cause an infinite loop on recursive functions.

This should handle issue:

1. WHENEVER SQLERROR EXIT SQL.SQLCODE
2. SPOOL ${SPOOL_FILE}
3. $RC returns oracle's exit code
4. cat from $SPOOL_FILE explains error

SPOOL_FILE=${LOG_DIR}/${LOG_FILE_NAME}.spool 

SQLPLUS_OUTPUT=`sqlplus -s  "$SFDC_WE_CORE" <<EOF 
        SET HEAD OFF
        SET AUTOPRINT OFF
        SET TERMOUT OFF
        SET SERVEROUTPUT ON

        SPOOL  ${SPOOL_FILE} 

        WHENEVER SQLERROR EXIT SQL.SQLCODE
        DECLARE 

        BEGIN
           foooo 
        --rollback; 
        END;
    /
    EOF` 

RC=$?

if [[ $RC != 0 ]] ; then

    echo " RDBMS exit code : $RC  "     | tee -a ${LOG_FILE}
    cat ${SPOOL_FILE}                   | tee -a ${LOG_FILE}

    cat ${LOG_FILE} | mail -s "Script ${INIT_EXE} failed on $SFDC_ENV" $SUPPORT_LIST

    exit 3

The JPA @Column Annotation

The nullable attribute of the @Column annotation has two purposes:

• it's used by the schema generation tool
• it's used by Hibernate during flushing the Persistence Context

Schema Generation Tool

The HBM2DDL schema generation tool translates the @Column(nullable = false) entity attribute to a NOT NULL constraint for the associated table column when generating the CREATE TABLE statement.

As I explained in the Hibernate User Guide, it's better to use a tool like Flyway instead of relying on the HBM2DDL mechanism for generating the database schema.

Persistence Context Flush

When flushing the Persistence Context, Hibernate ORM also uses the @Column(nullable = false) entity attribute:

new Nullability( session ).checkNullability( values, persister, true );

If the validation fails, Hibernate will throw a PropertyValueException, and prevents the INSERT or UPDATE statement to be executed needesly:

if ( !nullability[i] && value == null ) {
    //check basic level one nullablilty
    throw new PropertyValueException(
            "not-null property references a null or transient value",
            persister.getEntityName(),
            persister.getPropertyNames()[i]
        );    
}

The Bean Validation @NotNull Annotation

The @NotNull annotation is defined by Bean Validation and, just like Hibernate ORM is the most popular JPA implementation, the most popular Bean Validation implementation is the Hibernate Validator framework.

When using Hibernate Validator along with Hibernate ORM, Hibernate Validator will throw a ConstraintViolation when validating the entity.

Do you mean like this?

<!-- ... --->
<td>
   this text should be left justified
   and this text should be right justified?
</td>
<!-- ... --->

If yes

<!-- ... --->
<td>
   <p style="text-align: left;">this text should be left justified</p>
   <p style="text-align: right;">and this text should be right justified?</p>
</td>
<!-- ... --->

For just elements this can be used to find the index of an element amongst it's sibling elements:

function getElIndex(el) {
    for (var i = 0; el = el.previousElementSibling; i++);
    return i;
}

Note that previousElementSibling isn't supported in IE<9.

I can give you an example which results with the same problem, but it may not give you an answer to your question. (Additionally, in this example, I'm using my Maven 3 knowledge, which may not apply for Maven 2.)

In a multi-module maven project (contains modules A and B, where B depends on A), you can add also a test dependency on A from B.

This dependency may look as follows:

<dependency>
     <groupId>com.foo</groupId>
     <artifactId>A</artifactId>
     <type>test-jar</type> <!-- I'm not sure if there is such a thing in Maven 2, but there is definitely a way to achieve such dependency in Maven 2. -->
     <scope>test</scope>
</dependency>

(for more information refer to https://maven.apache.org/guides/mini/guide-attached-tests.html)
Note that the project A produces secondary artifact with a classifier tests where the test classes and test resources are located.

If you build your project with -Dmaven.test.skip=true, you will get a dependency resolution error as long as the test artifact wasn't found in your local repo or external repositories. The reason is that the tests classes were neither compiled nor the tests artifact was produced.
However, if you run your build with -DskipTests your tests artifact will be produced (though the tests won't run) and the dependency will be resolved.

class Feedback(models.Model):
   feedback = models.CharField(max_length=100)
   created = models.DateTimeField(auto_now_add=True)
   updated = models.DateTimeField(auto_now=True)

Here, we have created and updated columns that will have a timestamp when created, and when someone modified feedback.

auto_now_add will set time when an instance is created whereas auto_now will set time when someone modified his feedback.

You can use "translateX"

<div class="box">
<div class="absolute-right"></div>
</div>

<style type="text/css">
.box{
    text-align: right;
}
.absolute-right{
    display: inline-block;
    position: absolute;
}

/*The magic:*/
.absolute-right{
-moz-transform: translateX(-100%);
-ms-transform: translateX(-100%);
-webkit-transform: translateX(-100%);
-o-transform: translateX(-100%);
transform: translateX(-100%);
}
</style>

to get current router in angular 8 just do this

import {ActivatedRoute} from '@angular/router';

then inject it in constructor like

constructor(private route: ActivatedRoute){}

if you want get current route then use this route.url

if you have multiply name route like /home/pages/list and you wanna access individual then you can access each of like this route.url.value[0].path

value[0] will give home, value[1] will give you pages and value[2] will give you list

If you include $@ in a quoted string with other characters the behavior is very odd when there are multiple arguments, only the first argument is included inside the quotes.

Example:

#!/bin/bash
set -x
bash -c "true foo $@"

Yields:

$ bash test.sh bar baz
+ bash -c 'true foo bar' baz

But assigning to a different variable first:

#!/bin/bash
set -x
args="$@"
bash -c "true foo $args"

Yields:

$ bash test.sh bar baz
+ args='bar baz'
+ bash -c 'true foo bar baz'

I think you need to include the regex OR operator:

String[]tokens = pdfName.split("-|\\.");

What you have will match:
[DASH followed by DOT together] -.
not
[DASH or DOT any of them] - or .

If feed isn't well-formed XML, you're supposed to reject it, no exceptions. You're entitled to call feed creator a bozo.

Otherwise you're paving way to mess that HTML ended up in.

In my case, the folder which served the files was a symbolic link to another folder, made with

ln -sf /origin /var/www/destination

Even though the permissions (user and group) where correct on the destination folder (the symbolic link), I still had the error because Nginx needed to have permissions to the origin folder whole's hierarchy as well.

This is partly implemented in foundation 5.

In file _type.scss they have two sets of header variables:

// We use these to control header font sizes
// for medium screens and above

$h1-font-size: rem-calc(44) !default;
$h2-font-size: rem-calc(37) !default;
$h3-font-size: rem-calc(27) !default;
$h4-font-size: rem-calc(23) !default;
$h5-font-size: rem-calc(18) !default;
$h6-font-size: 1rem !default;


// We use these to control header size reduction on small screens
$h1-font-reduction: rem-calc(10) !default;
$h2-font-reduction: rem-calc(10) !default;
$h3-font-reduction: rem-calc(5) !default;
$h4-font-reduction: rem-calc(5) !default;
$h5-font-reduction: 0 !default;
$h6-font-reduction: 0 !default;

For medium up, they generate sizes based on the first set of variables:

@media #{$medium-up} {
    h1,h2,h3,h4,h5,h6 { line-height: $header-line-height; }
    h1 { font-size: $h1-font-size; }
    h2 { font-size: $h2-font-size; }
    h3 { font-size: $h3-font-size; }
    h4 { font-size: $h4-font-size; }
    h5 { font-size: $h5-font-size; }
    h6 { font-size: $h6-font-size; }
}

And for default-i.e small screens, they use a second set of variables to generates CSS:

h1 { font-size: $h1-font-size - $h1-font-reduction; }
h2 { font-size: $h2-font-size - $h2-font-reduction; }
h3 { font-size: $h3-font-size - $h3-font-reduction; }
h4 { font-size: $h4-font-size - $h4-font-reduction; }
h5 { font-size: $h5-font-size - $h5-font-reduction; }
h6 { font-size: $h6-font-size - $h6-font-reduction; }

You can use these variables and override in your custom scss file to set font sizes for respective screen sizes.

You can also use BreakIterator.getWordInstance.

foreach ($arquivos as $key => $item) {
   reset($arquivos);
   // FIRST AHEAD
   if ($key === key($arquivos) || $key !== end(array_keys($arquivos)))
       $pdf->cat(null, null, $key);

   // LAST
   if ($key === end(array_keys($arquivos))) {
       $pdf->cat(null, null, $key)
           ->execute();
   }
}

In Windows it worked for me only after trying the following: 1. Open cmd inside the folder where "requests" is unpacked. (CTRL+SHIFT+right mouse click, choose the appropriate popup menu item) 2. (Here is the path to your pip3.exe)\pip3.exe install requests Done

I had a case when I needed to insert children into the modal conditionally. Something like this, bellow.

const [view, setView] = useState(VIEWS.SomeView)

return (
    <Modal onClose={onClose}>
      {VIEWS.Result === view ? (
        <Result onDeny={() => setView(VIEWS.Details)} />
      ) : VIEWS.Details === view ? (
        <Details onDeny={() => setView(VIEWS.Result) /> />
      ) : null}
    </Modal>
  )

So !parent.contains(event.target) doesn't work here, because once you detach children, parent (modal) doesn't contain event.target anymore.

The solution I had (which works so far and have no any issue) is to write something like this:

const listener = (event: MouseEvent) => {
   if (parentNodeRef && !event.path.includes(parentNodeRef)) callback()
}

If parent contained element from already detached tree, it wouldn't fire callback.

EDIT: event.path is new and doesn't exit in all browsers yet. Use compoesedPath instead.

No, it is not possible. Stack Overflow wants me to answer with a longer answer, so I will say no again.

Documentation: https://docs.microsoft.com/en-us/sql/t-sql/statements/backup-transact-sql#compatibility

Backups that are created by more recent version of SQL Server cannot be restored in earlier versions of SQL Server.

Assuming that I have understood your scenario correctly, this is what I would call the right way to do this:

Start from a higher-level description of your database! You have employees, and employees can be "ce" employees and "sn" employees (whatever those are). In object-oriented terms, there is a class "employee", with two sub-classes called "ce employee" and "sn employee".

Then you translate this higher-level description to three tables: employees, employees_ce and employees_sn:

• employees(id, name)
• employees_ce(id, ce-specific stuff)
• employees_sn(id, sn-specific stuff)

Since all employees are employees (duh!), every employee will have a row in the employees table. "ce" employees also have a row in the employees_ce table, and "sn" employees also have a row in the employees_sn table. employees_ce.id is a foreign key to employees.id, just as employees_sn.id is.

To refer to an employee of any kind (ce or sn), refer to the employees table. That is, the foreign key you had trouble with should refer to that table!

These are the main factors involved:

1. member variable (default OK)
2. static variable (default OK)
3. final member variable (not initialized, must set on constructor)
4. final static variable (not initialized, must set on a static block {})
5. local variable (not initialized)

Note 1: you must initialize final member variables on every implemented constructor!

Note 2: you must initialize final member variables inside the block of the constructor itself, not calling another method that initializes them. For instance, this is not valid:

private final int memberVar;

public Foo() {
    // Invalid initialization of a final member
    init();
}

private void init() {
    memberVar = 10;
}

Note 3: arrays are Objects in Java, even if they store primitives.

Note 4: when you initialize an array, all of its items are set to default, independently of being a member or a local array.

I am attaching a code example, presenting the aforementioned cases:

public class Foo {
    // Static and member variables are initialized to default values

    // Primitives
    private int a; // Default 0
    private static int b; // Default 0

    // Objects
    private Object c; // Default NULL
    private static Object d; // Default NULL

    // Arrays (note: they are objects too, even if they store primitives)
    private int[] e; // Default NULL
    private static int[] f; // Default NULL

    // What if declared as final?

    // Primitives
    private final int g; // Not initialized. MUST set in the constructor
    private final static int h; // Not initialized. MUST set in a static {}

    // Objects
    private final Object i; // Not initialized. MUST set in constructor
    private final static Object j; // Not initialized. MUST set in a static {}

    // Arrays
    private final int[] k; // Not initialized. MUST set in constructor
    private final static int[] l; // Not initialized. MUST set in a static {}

    // Initialize final statics
    static {
        h = 5;
        j = new Object();
        l = new int[5]; // Elements of l are initialized to 0
    }

    // Initialize final member variables
    public Foo() {
        g = 10;
        i = new Object();
        k = new int[10]; // Elements of k are initialized to 0
    }

    // A second example constructor
    // You have to initialize final member variables to every constructor!
    public Foo(boolean aBoolean) {
        g = 15;
        i = new Object();
        k = new int[15]; // Elements of k are initialized to 0
    }

    public static void main(String[] args) {
        // Local variables are not initialized
        int m; // Not initialized
        Object n; // Not initialized
        int[] o; // Not initialized

        // We must initialize them before use
        m = 20;
        n = new Object();
        o = new int[20]; // Elements of o are initialized to 0
    }
}

Not exactly sure why, but changing the inner CSS to

display: inline-block;

seems to work.

You have to remove the IMEX=1 if you want to update. ;)

"IMEX=1; tells the driver to always read "intermixed" (numbers, dates, strings etc) data columns as text. Note that this option might affect excel sheet write access negative." https://www.connectionstrings.com/excel/

To all those who know more than me, rather than marking it unhelpful or misleading, read it one more time. I had issues with my Virtual Machine (VM) becoming unresponsive due to all resources being consumed by locked threads, so killing threads is the only option I had. I am not recommending this to anyone who are running long queries but may help to those who are stuck with unresponsive VM or something. Its up-to individuals to take the call. Yes it will kill your query but it saved my VM machine being destroyed.

Serverstack already answered similar question. It solved my issue with SQL on VM machine. Please check here

You need to run following command to fix issues with indexes.

exec sp_updatestats

This is what I use:

# Generate a [0-9a-zA-Z] string
ALPHABET = map(str,range(0, 10)) + map(chr, range(97, 123) + range(65, 91))

def encode_id(id_number, alphabet=ALPHABET):
    """Convert an integer to a string."""
    if id_number == 0:
        return alphabet[0]

    alphabet_len = len(alphabet) # Cache

    result = ''
    while id_number > 0:
        id_number, mod = divmod(id_number, alphabet_len)
        result = alphabet[mod] + result

    return result

def decode_id(id_string, alphabet=ALPHABET):
    """Convert a string to an integer."""
    alphabet_len = len(alphabet) # Cache
    return sum([alphabet.index(char) * pow(alphabet_len, power) for power, char in enumerate(reversed(id_string))])

It's very fast and can take long integers.

Try This :) I created my on model of count all results

in library_model

function count_all_results($column_name = array(),$where=array(), $table_name = array())
{
        $this->db->select($column_name);
        // If Where is not NULL
        if(!empty($where) && count($where) > 0 )
        {
            $this->db->where($where);
        }
        // Return Count Column
        return $this->db->count_all_results($table_name[0]);//table_name array sub 0
}

Your Controller will look like this

public function my_method()
{
  $data = array(
     $countall = $this->model->your_method_model()
  );
   $this->load->view('page',$data);
}

Then Simple Call The Library Model In Your Model

function your_method_model()
{
        return $this->library_model->count_all_results(
               ['id'],
               ['where],
               ['table name']
           );
}

To check if the javascript in nonexistant.js returned no error you have to add a variable inside http://fail.org/nonexistant.js like var isExecuted = true; and then check if it exists when the script tag is loaded.

However if you only want to check that the nonexistant.js returned without a 404 (meaning it exists), you can try with a isLoaded variable ...

var isExecuted = false;
var isLoaded = false;
script_tag.onload = script_tag.onreadystatechange = function() {
    if(!this.readyState ||
        this.readyState == "loaded" || this.readyState == "complete") {
        // script successfully loaded
        isLoaded = true;

        if(isExecuted) // no error
    }
}

This will cover both cases.

First call startactivity() then use finish()

void myFunc(char* str, char c)
{
    char* ptr;
    int index;

    ptr = strchr(str, c);
    if (ptr == NULL)
    {
        printf("Character not found\n");
        return;
    }

    index = ptr - str;

    printf("The index is %d\n", index);
    ASSERT(str[index] == c);  // Verify that the character at index is the one we want.
}

This code is currently untested, but it demonstrates the proper concept.

How about SymPy? Their solver looks like what you need. Have a look at their source code if you want to build the library yourself…

One line working answer:

$url = "http://www.yoursite/one/two/three/drink";
echo $end = end((explode('/', $url)));

Output: drink

As others have said, you can't put both in one project. However, if you just have a small piece of C# or VB code that you want to include in a project in the other language, there are automatic conversion tools. They're not perfect, but they do most things pretty well. Also, SharpDevelop has a conversion utility built in.

I just left the terminal open for a minute. then it started working fine again.

Another approach to this issue could be to create a self extracting executable (.exe) using something like winzip and use this as the install vector rather than the zip file. Similarly, you could use NSIS to create an executable installer and use that instead of the zip.

log.retention.hours is a property of a broker which is used as a default value when a topic is created. When you change configurations of currently running topic using kafka-topics.sh, you should specify a topic-level property.

A topic-level property for log retention time is retention.ms.

From Topic-level configuration in Kafka 0.8.1 documentation:

• Property: retention.ms
• Default: 7 days
• Server Default Property: log.retention.minutes
• Description: This configuration controls the maximum time we will retain a log before we will discard old log segments to free up space if we are using the "delete" retention policy. This represents an SLA on how soon consumers must read their data.

So the correct command depends on the version. Up to 0.8.2 (although docs still show its use up to 0.10.1) use kafka-topics.sh --alter and after 0.10.2 (or perhaps from 0.9.0 going forward) use kafka-configs.sh --alter

$ bin/kafka-topics.sh --zookeeper zk.yoursite.com --alter --topic as-access --config retention.ms=86400000
 

You can check whether the configuration is properly applied with the following command.

$ bin/kafka-topics.sh --describe --zookeeper zk.yoursite.com --topic as-access

Then you will see something like below.

Topic:as-access  PartitionCount:3  ReplicationFactor:3  Configs:retention.ms=86400000

defaultdict is great when the default value is static, like a new list, but not so much if it's dynamic.

For example, I need a dictionary to map strings to unique ints. defaultdict(int) will always use 0 for the default value. Likewise, defaultdict(intGen()) always produces 1.

Instead, I used a regular dict:

nextID = intGen()
myDict = {}
for lots of complicated stuff:
    #stuff that generates unpredictable, possibly already seen str
    strID = myDict.setdefault(myStr, nextID())

Note that dict.get(key, nextID()) is insufficient because I need to be able to refer to these values later as well.

intGen is a tiny class I build that automatically increments an int and returns its value:

class intGen:
    def __init__(self):
        self.i = 0

    def __call__(self):
        self.i += 1
    return self.i

If someone has a way to do this with defaultdict I'd love to see it.

This work in C#:

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    int idx = e.RowIndex;
    DataGridViewRow row = dataGridView1.Rows[idx];
    long newNo = idx;
    if (!_RowNumberStartFromZero)
        newNo += 1;

    long oldNo = -1;
    if (row.HeaderCell.Value != null)
    {
        if (IsNumeric(row.HeaderCell.Value))
        {
            oldNo = System.Convert.ToInt64(row.HeaderCell.Value);
        }
    }

    if (newNo != oldNo)
    {
        row.HeaderCell.Value = newNo.ToString();
        row.HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleRight;
    }
}

I am using Spring Boot and had this issue with a collection, in spite of not directly overwriting it, because I am declaring an extra field for the same collection with a custom serializer and deserializer in order to provide a more frontend-friendly representation of the data:

  public List<Attribute> getAttributes() {
    return attributes;
  }

  public void setAttributes(List<Attribute> attributes) {
    this.attributes = attributes;
  }

  @JsonSerialize(using = AttributeSerializer.class)
  public List<Attribute> getAttributesList() {
    return attributes;
  }

  @JsonDeserialize(using = AttributeDeserializer.class)
  public void setAttributesList(List<Attribute> attributes) {
    this.attributes = attributes;
  }

It seems that even though I am not overwriting the collection myself, the deserialization does it under the hood, triggering this issue all the same. The solution was to change the setter associated with the deserializer so that it would clear the list and add everything, rather than overwrite it:

  @JsonDeserialize(using = AttributeDeserializer.class)
  public void setAttributesList(List<Attribute> attributes) {
    this.attributes.clear();
    this.attributes.addAll(attributes);
  }

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

Use:

sudo DEBIAN_FRONTEND=noninteractive apt-get install -y mysql-server

sudo mysql -h127.0.0.1 -P3306 -uroot -e"UPDATE mysql.user SET password = PASSWORD('yourpassword') WHERE user = 'root'"

There is another solution by lord.garbage to run GUI apps in a container without using VNC, SSH and X11 forwarding. It is mentioned here too.

I have tried many of the commands listed above, however none worked, even after setting my path to include the directory where I installed Python.

The command py -3 file.py always works for me, and if I want to run Python 2 code, as long as Python 2 is in my path, just changing the command to py -2 file.py works perfectly.

I am using Windows, so I'm not too sure if this command will work on Linux, or Mac, but it's worth a try.

Very safe:

the annual risk of a given person being hit by a meteorite is estimated to be one chance in 17 billion, which means the probability is about 0.00000000006 (6 × 10^-11), equivalent to the odds of creating a few tens of trillions of UUIDs in a year and having one duplicate. In other words, only after generating 1 billion UUIDs every second for the next 100 years, the probability of creating just one duplicate would be about 50%.

Caveat:

However, these probabilities only hold when the UUIDs are generated using sufficient entropy. Otherwise, the probability of duplicates could be significantly higher, since the statistical dispersion might be lower. Where unique identifiers are required for distributed applications, so that UUIDs do not clash even when data from many devices is merged, the randomness of the seeds and generators used on every device must be reliable for the life of the application. Where this is not feasible, RFC4122 recommends using a namespace variant instead.

I hit this when trying to compile python, numpy, scipy, matplotlib in my own VIRTUAL_ENV

Before installing matplotlib you have to build and install: pygobject pycairo pygtk

And then do it with matplotlib: Before building matplotlib check with 'python ./setup.py build --help' if 'gtkagg' backend is enabled. Then build and install

Before export PKG_CONFIG_PATH=$VIRTUAL_ENV/lib/pkgconfig

If you know that there are not going to be empty cells in between, the fastest way is this.

=INDIRECT("O"&(COUNT(O:O,"<>""")))

It just counts the non-empty cells and refers to the appropriate cell.

It can be used for a specific range as well.

=INDIRECT("O"&(COUNT(O4:O34,"<>""")+3))

This returns the last non empty cell in the range O4:O34.

This also happens if you forget selfdeclaration inside class methods.

Example:

class Example():
    def is_overlapping(x1, x2, y1, y2):
        # Thanks to https://stackoverflow.com/a/12888920/940592
        return max(x1, y1) <= min(x2, y2)

Fails calling it like self.is_overlapping(x1=2, x2=4, y1=3, y2=5) with:

{TypeError} is_overlapping() got multiple values for argument 'x1'

WORKS:

class Example():
    def is_overlapping(self, x1, x2, y1, y2):
        # Thanks to https://stackoverflow.com/a/12888920/940592
        return max(x1, y1) <= min(x2, y2)

In jQuery 3 and perhaps earlier versions, the following simpler config also works for individual requests:

$.ajax(
        'https://foo.bar.com,
        {
            dataType: 'json',
            xhrFields: {
                withCredentials: true
            },
            success: successFunc
        }
    );

The full error I was getting in Firefox Dev Tools -> Network tab (in the Security tab for an individual request) was:

An error occurred during a connection to foo.bar.com.SSL peer was unable to negotiate an acceptable set of security parameters.Error code: SSL_ERROR_HANDSHAKE_FAILURE_ALERT

From Java 9+ and up, you can define a new URLStreamHandlerProvider. The URL class uses the service loader framework to load it at run time.

Create a provider:

package org.example;

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLStreamHandler;
import java.net.spi.URLStreamHandlerProvider;

public class ClasspathURLStreamHandlerProvider extends URLStreamHandlerProvider {

    @Override
    public URLStreamHandler createURLStreamHandler(String protocol) {
        if ("classpath".equals(protocol)) {
            return new URLStreamHandler() {
                @Override
                protected URLConnection openConnection(URL u) throws IOException {
                    return ClassLoader.getSystemClassLoader().getResource(u.getPath()).openConnection();
                }
            };
        }
        return null;
    }

}

Create a file called java.net.spi.URLStreamHandlerProvider in the META-INF/services directory with the contents:

org.example.ClasspathURLStreamHandlerProvider

Now the URL class will use the provider when it sees something like:

URL url = new URL("classpath:myfile.txt");

Difference: When I first installed node, it installed as 'nodejs'. When I upgraded it, it created 'node'. By executing node, we are actually executing nodejs. Node is just a reference to nodejs. From my experience, when I upgraded, it affected both the versions (as it is supposed to). When I do nodejs -v or node -v, I get the new version.

Upgrading: npm update is used to update the packages in the current directory. Check https://docs.npmjs.com/cli/update

To upgrade node version, based on the OS you are using, follow the commands here https://nodejs.org/en/download/package-manager/

Both NSQueueOperations and GCD allow executing heavy computation task in the background on separate threads by freeing the UI Application Main Tread.

Well, based previous post we see NSOperations has addDependency so that you can queue your operation one after another sequentially.

But I also read about GCD serial Queues you can create run your operations in the queue using dispatch_queue_create. This will allow running a set of operations one after another in a sequential manner.

NSQueueOperation Advantages over GCD:

1. It allows to add dependency and allows you to remove dependency so for one transaction you can run sequential using dependency and for other transaction run concurrently while GCD doesn't allow to run this way.

2. It is easy to cancel an operation if it is in the queue it can be stopped if it is running.

3. You can define the maximum number of concurrent operations.

4. You can suspend operation which they are in Queue

5. You can find how many pending operations are there in queue.

here is my answer:

public class WigetControl {
private Resources res;

public WigetControl(Resources res) 
{
    this.res = res;
}

public void setButtonDisable(Button mButton)
{
    mButton.setBackgroundColor(res.getColor(R.color.loginbutton_unclickable));
    mButton.setEnabled(false);
}

}

and the call can be like this:

        WigetControl control = new WigetControl(getResources());
        control.setButtonDisable(btNext);

Here is a simple way to do it

var lastPlayerControlCommand = this.ObjectContext.PlayerControlCommands
                                .Where(c => c.PlayerID == player.ID)
                                .OrderByDescending(t=>t.CreationTime)
                                .FirstOrDefault();

The working solution listed are great, but the problem occurs when you want multiple default home for your git-bash.

A simple workaround is to start git-bash using bat script.

git-bash-to-htdocs.bat

cd C:\xampp\htdocs
"C:\Program Files\Git\git-bash.exe" 

The above of course assume git-bash is installed at C:\Program Files\Git\git-bash.exe

You can create multiple .bat file so your git-bash can start where it want to be

Run this:

 sudo -u postgres psql

OR

psql -U postgres

in your terminal to get into postgres

NB: If you're on a Mac and both of the commands above failed jump to the section about Mac below

postgres=#

Run

CREATE USER new_username;

Note: Replace new_username with the user you want to create, in your case that will be tom.

postgres=# CREATE USER new_username;
CREATE ROLE

Since you want that user to be able to create a DB, you need to alter the role to superuser

postgres=# ALTER USER new_username SUPERUSER CREATEDB;
ALTER ROLE

To confirm, everything was successful,

postgres=# \du
                         List of roles
 Role name |                   Attributes                   | Member of 
-----------+------------------------------------------------+-----------
new_username     | Superuser, Create DB                           | {}
postgres         | Superuser, Create role, Create DB, Replication | {}
root             | Superuser, Create role, Create DB              | {}

postgres=# 

Update/Modification (For Mac):

I recently encountered a similar error on my Mac:

psql: FATAL: role "postgres" does not exist

This was because my installation was setup with a database superuser whose role name is the same as your login (short) name.

But some linux scripts assume the superuser has the traditional role name of postgres

How did I resolve this?

If you installed with homebrew run:

/usr/local/opt/postgres/bin/createuser -s postgres

If you're using a specific version of postgres, say 10.5 then run:

/usr/local/Cellar/postgresql/10.5/bin/createuser -s postgres

OR:

/usr/local/Cellar/postgresql/10.5/bin/createuser -s new_username

OR:

/usr/local/opt/postgresql@11/bin/createuser -s postgres

If you installed with postgres.app for Mac run:

/Applications/Postgres.app/Contents/Versions/10.5/bin/createuser -s postgres

P.S: replace 10.5 with your PostgreSQL version

[0-9]{4,6} can be shortened to \d{4,6}

It also gives you good results:

exec("convert -geometry 1600x1600 -density 200x200 -quality 100 test.pdf test_image.jpg");

Have a look at the ReadAsset.java from API samples that come with the SDK.

       try {
        InputStream is = getAssets().open("read_asset.txt");

        // We guarantee that the available method returns the total
        // size of the asset...  of course, this does mean that a single
        // asset can't be more than 2 gigs.
        int size = is.available();

        // Read the entire asset into a local byte buffer.
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();

        // Convert the buffer into a string.
        String text = new String(buffer);

        // Finally stick the string into the text view.
        TextView tv = (TextView)findViewById(R.id.text);
        tv.setText(text);
    } catch (IOException e) {
        // Should never happen!
        throw new RuntimeException(e);
    }

Use this Layout in your xml file

<LinearLayout
  android:id="@+id/contacts_type"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:visibility="gone">
</LinearLayout>

Define your layout in .class file

 LinearLayout linearLayout = (LinearLayout) findViewById(R.id.contacts_type);

Now if you want to display this layout just write

 linearLayout.setVisibility(View.VISIBLE);

and if you want to hide layout just write

 linearLayout.setVisibility(View.INVISIBLE);

If you add the android:theme="@style/Theme.AppCompat.Light" to <application> in AndroidManifest.xml file, problem is solving.

Old topic, but I think I found another descent solution. Adding class="row" to a div will result in this CSS configuration:

.row {
    display: -webkit-box;
    display: flex;
    flex-wrap: wrap;
    margin-right: -15px;
    margin-left: -15px;
}

We want to keep the first 3 rules and we can do this with class="d-flex flex-wrap" (see https://getbootstrap.com/docs/4.1/utilities/flex/):

.flex-wrap {
    flex-wrap: wrap !important;
}
.d-flex {
    display: -webkit-box !important;
    display: flex !important;
}

It adds !important rules though but it shouldn't be a problem in most cases...

Here is an alternative syntax for the ternary operator:

{ this.state.showMyComponent ? <MyComponent /> : null }

is equivalent to:

{ this.state.showMyComponent && <MyComponent /> }

Learn why

Also alternative syntax with display: 'none';

<MyComponent style={this.state.showMyComponent ? {} : { display: 'none' }} />

However, if you overuse display: 'none', this leads to DOM pollution and ultimately slows down your application.

MySQL can index the first x characters of a column,but a TEXT type is of variable length so mysql cant assure the uniqueness of the column.If you still want text column,use VARCHAR.

I just wanted to add this version because this is such a useful thread and I think this is a very simple implementation. I have used this multiple times in various types if multithreaded application:

normally $gitdir = ".git". You need to update the username and the Gerrit link.

Masking means to keep/change/remove a desired part of information. Lets see an image-masking operation; like- this masking operation is removing any thing that is not skin-

We are doing AND operation in this example. There are also other masking operators- OR, XOR.

Bit-Masking means imposing mask over bits. Here is a bit-masking with AND-

     1 1 1 0 1 1 0 1   [input]
(&)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     0 0 1 0 1 1 0 0  [output]

So, only the middle 4 bits (as these bits are 1 in this mask) remain.

Lets see this with XOR-

     1 1 1 0 1 1 0 1   [input]
(^)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     1 1 0 1 0 0 0 1  [output]

Now, the middle 4 bits are flipped (1 became 0, 0 became 1).

So, using bit-mask we can access individual bits [examples]. Sometimes, this technique may also be used for improving performance. Take this for example-

bool isOdd(int i) {
    return i%2;
}

This function tells if an integer is odd/even. We can achieve the same result with more efficiency using bit-mask-

bool isOdd(int i) {
    return i&1;
}

Short Explanation: If the least significant bit of a binary number is 1 then it is odd; for 0 it will be even. So, by doing AND with 1 we are removing all other bits except for the least significant bit i.e.:

     55  ->  0 0 1 1 0 1 1 1   [input]
(&)   1  ->  0 0 0 0 0 0 0 1    [mask]
---------------------------------------
      1  <-  0 0 0 0 0 0 0 1  [output]

if you want to use ORDER BY, just add:

criteria.setProjection(
    Projections.distinct(
        Projections.projectionList()
        .add(Projections.id())
        .add(Projections.property("the property that you want to ordered by"))
    )
);

Left padding String extension similar to padding(toLength:withPad:startingAt:) in Foundation

extension String {
    func leftPadding(toLength: Int, withPad: String = " ") -> String {

        guard toLength > self.characters.count else { return self }

        let padding = String(repeating: withPad, count: toLength - self.characters.count)
        return padding + self
    }
}

Usage:

let s = String(123)
s.leftPadding(toLength: 8, withPad: "0") // "00000123"

For me only the following combination worked, tested from API 18 to 24

app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp"

where in "app" is : xmlns:app="http://schemas.android.com/apk/res-auto"

for example.

I've had the same issue in a VB6 program I'm writing, where a Form uses a ScriptControl object to run VBScripts selected by the User.

It worked fine until the other day, when it suddenly started displaying 'Runtime error 429' when the VBScript attempted to create a Scripting.FileSystemObject.

After going mad for an entire day, trying all the solutions proposed here, I began suspecting the problem was in my application.

Fortunately, I had a backup version of that form: I compared their codes, and discovered that inadvertently I had set UseSafeSubset property of my ScriptControl object to True.

It was the only difference in the form, and after restoring the backup copy it worked like a charm.

Hope this can be useful to someone. Up with VB6! :-)

For new Qt users this is a little more confusing than it seems if you are using QT Designer and .ui files.

Initially I tried to use ui->setWindowTitle, but that doesn't exist. ui is not a QDialog or a QMainWindow.

The owner of the ui is the QDialog or QMainWindow, the .ui just describes how to lay it out. In that case, you would use:

this->setWindowTitle("New Title");

I hope this helps someone else.

You can have ArrayList with elements which would be ArrayLists itself.

Another approach

Say you create a class clsBitcoinPublicKey

In the class module create an ADDITIONAL subroutine, that acts as you would want the real constructor to behave. Below I have named it ConstructorAdjunct.

Public Sub ConstructorAdjunct(ByVal ...)

 ...

End Sub

From the calling module, you use an additional statement

Dim loPublicKey AS clsBitcoinPublicKey

Set loPublicKey = New clsBitcoinPublicKey

Call loPublicKey.ConstructorAdjunct(...)

The only penalty is the extra call, but the advantage is that you can keep everything in the class module, and debugging becomes easier.

After adding the icon to the toolbar and when modifying the selected icon, the ampersand in the name input is specifying that the next character is the character used along with Alt for the shortcut. Since you must select a display option from the Modify Selection drop down menu that includes displaying the text, you could also write &C in the name field and get the same result as &Comment Block (without the lengthy text).

Use bind function instead. Make it more friendly.

Example:

var clickHandler = "click";

if('ontouchstart' in document.documentElement){
    clickHandler = "touchstart";
}

$(".button").bind(clickHandler,function(){
    alert('Visible on touch and non-touch enabled devices');
});

You can use this one 24H, seconds are optional

^([0-1]?[0-9]|[2][0-3]):([0-5][0-9])(:[0-5][0-9])?$

The usual way to check whether something can be converted to an int is to try it and see, following the EAFP principle:

try:
    int_value = int(string_value)
except ValueError:
    # it wasn't an int, do something appropriate
else:
    # it was an int, do something appropriate

So, in your case:

for item in mylist:
    try:
        int_value = int(item)
    except ValueError:
        pass
    else:
        mynewlist.append(item) # or append(int_value) if you want numbers

In most cases, a loop around some trivial code that ends with mynewlist.append(item) can be turned into a list comprehension, generator expression, or call to map or filter. But here, you can't, because there's no way to put a try/except into an expression.

But if you wrap it up in a function, you can:

def raises(func, *args, **kw):
    try:
        func(*args, **kw)
    except:
        return True
    else:
        return False

mynewlist = [item for item in mylist if not raises(int, item)]

… or, if you prefer:

mynewlist = filter(partial(raises, int), item)

It's cleaner to use it this way:

def raises(exception_types, func, *args, **kw):
    try:
        func(*args, **kw)
    except exception_types:
        return True
    else:
        return False

This way, you can pass it the exception (or tuple of exceptions) you're expecting, and those will return True, but if any unexpected exceptions are raised, they'll propagate out. So:

mynewlist = [item for item in mylist if not raises(ValueError, int, item)]

… will do what you want, but:

mynewlist = [item for item in mylist if not raises(ValueError, item, int)]

… will raise a TypeError, as it should.

Thank you so much to @Code in another answer. I can read any JSON file thanks to your code. Now, I'm trying to organize all the elements by levels, for could use them!

I was working with Android reading a JSON from an URL and the only I had to change was the lines

Set<Object> set = jsonObject.keySet(); Iterator<Object> iterator = set.iterator();

for

Iterator<?> iterator = jsonObject.keys();

I share my implementation, to help someone:

public void parseJson(JSONObject jsonObject) throws ParseException, JSONException {

    Iterator<?> iterator = jsonObject.keys();
    while (iterator.hasNext()) {
        String obj = iterator.next().toString();

        if (jsonObject.get(obj) instanceof JSONArray) {
            //Toast.makeText(MainActivity.this, "Objeto: JSONArray", Toast.LENGTH_SHORT).show();
            //System.out.println(obj.toString());
            TextView txtView = new TextView(this);
            txtView.setText(obj.toString());
            layoutIzq.addView(txtView);
            getArray(jsonObject.get(obj));
        } else {
            if (jsonObject.get(obj) instanceof JSONObject) {
                //Toast.makeText(MainActivity.this, "Objeto: JSONObject", Toast.LENGTH_SHORT).show();
                parseJson((JSONObject) jsonObject.get(obj));
            } else {
                //Toast.makeText(MainActivity.this, "Objeto: Value", Toast.LENGTH_SHORT).show();
                //System.out.println(obj.toString() + "\t"+ jsonObject.get(obj));
                TextView txtView = new TextView(this);
                txtView.setText(obj.toString() + "\t"+ jsonObject.get(obj));
                layoutIzq.addView(txtView);
            }
        }
    }
}

#container img{
 height:100%;
 width:100%;   
}

if there are multiple java processes and you wish to kill them with one command try the below command

kill -9 $(ps -ef | pgrep -f "java")

replace "java" with any process string identifier , to kill anything else.

select max(id) from customers

for Ubuntu / Debian :

# sudo apt-get install build-essential

For RHEL/CentOS

#rpm -qa | grep gcc
# yum install gcc glibc glibc-common gd gd-devel -y

or

 # yum groupinstall "Development tools" -y

More details refer the link

Like this:

>>>mystr = "abcdefghijkl"
>>>mystr[-4:]
'ijkl'

This slices the string's last 4 characters. The -4 starts the range from the string's end. A modified expression with [:-4] removes the same 4 characters from the end of the string:

>>>mystr[:-4]
'abcdefgh'

For more information on slicing see this Stack Overflow answer.

Assuming you have pushed most recent changes to the server:

1. Close Visual Studio and delete your local copy of the project
2. Open Visual Studio, go to Team Explorer tab, click Manage Connections. (plug)
3. Click the dropdown arrow next to Manage Connections, Connect to a Project
4. Select the project, confirm the local path, and click the Connect button.

Once you reopen the project both commits and changes should be zero.

Try (maybe as root)

lsof -i -P

and grep the output for the port you are looking for.

For example to check for port 80 do

lsof -i -P | grep :80

I recently came across this requirement myself, and I decided to implement an ActionFilter to handle this.

public class ArrayInputAttribute : ActionFilterAttribute
{
    private readonly string _parameterName;

    public ArrayInputAttribute(string parameterName)
    {
        _parameterName = parameterName;
        Separator = ',';
    }

    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        if (actionContext.ActionArguments.ContainsKey(_parameterName))
        {
            string parameters = string.Empty;
            if (actionContext.ControllerContext.RouteData.Values.ContainsKey(_parameterName))
                parameters = (string) actionContext.ControllerContext.RouteData.Values[_parameterName];
            else if (actionContext.ControllerContext.Request.RequestUri.ParseQueryString()[_parameterName] != null)
                parameters = actionContext.ControllerContext.Request.RequestUri.ParseQueryString()[_parameterName];

            actionContext.ActionArguments[_parameterName] = parameters.Split(Separator).Select(int.Parse).ToArray();
        }
    }

    public char Separator { get; set; }
}

I am applying it like so (note that I used 'id', not 'ids', as that is how it is specified in my route):

[ArrayInput("id", Separator = ';')]
public IEnumerable<Measure> Get(int[] id)
{
    return id.Select(i => GetData(i));
}

And the public url would be:

/api/Data/1;2;3;4

You may have to refactor this to meet your specific needs.

Way 1: only works for dataURL, not for other types of url.

 function dataURLtoFile(dataurl, filename) {_x000D_
 _x000D_
        var arr = dataurl.split(','),_x000D_
            mime = arr[0].match(/:(.*?);/)[1],_x000D_
            bstr = atob(arr[1]), _x000D_
            n = bstr.length, _x000D_
            u8arr = new Uint8Array(n);_x000D_
            _x000D_
        while(n--){_x000D_
            u8arr[n] = bstr.charCodeAt(n);_x000D_
        }_x000D_
        _x000D_
        return new File([u8arr], filename, {type:mime});_x000D_
    }_x000D_
    _x000D_
    //Usage example:_x000D_
    var file = dataURLtoFile('data:text/plain;base64,aGVsbG8gd29ybGQ=','hello.txt');_x000D_
    console.log(file);

Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)

 //return a promise that resolves with a File instance_x000D_
    function urltoFile(url, filename, mimeType){_x000D_
        return (fetch(url)_x000D_
            .then(function(res){return res.arrayBuffer();})_x000D_
            .then(function(buf){return new File([buf], filename,{type:mimeType});})_x000D_
        );_x000D_
    }_x000D_
    _x000D_
    //Usage example:_x000D_
    urltoFile('data:text/plain;base64,aGVsbG8gd29ybGQ=', 'hello.txt','text/plain')_x000D_
    .then(function(file){ console.log(file);});

<?php 
    $sessionDetails = $this->Session->read('Auth.User');

    if (!empty($sessionDetails)) {


        $loginFlag = 1;
        # code...
    }else{
        $loginFlag =  0;
    }


?>

<script type="text/javascript">

    var sessionValue = '<?php echo $loginFlag; ?>';
    if (sessionValue = 0) {

        //model show
    }
</script>

If you have standart output redirect to "nohup.out" just see who use this file

lsof | grep nohup.out

SurfaceView probably does not work like a regular View in this regard.

Instead, do the following:

1. Put your SurfaceView inside of a FrameLayout or RelativeLayout in your layout XML file, since both of those allow stacking of widgets on the Z-axis
2. Move your drawing logic into a separate custom View class
3. Add an instance of the custom View class to the layout XML file as a child of the FrameLayout or RelativeLayout, but have it appear after the SurfaceView

This will cause your custom View class to appear to float above the SurfaceView.

See here for a sample project that layers popup panels above a SurfaceView used for video playback.

I created my own functions which work really nicely:

def writeDict(dict, filename, sep):
    with open(filename, "a") as f:
        for i in dict.keys():            
            f.write(i + " " + sep.join([str(x) for x in dict[i]]) + "\n")

It will store the keyname first, followed by all values. Note that in this case my dict contains integers so that's why it converts to int. This is most likely the part you need to change for your situation.

def readDict(filename, sep):
    with open(filename, "r") as f:
        dict = {}
        for line in f:
            values = line.split(sep)
            dict[values[0]] = {int(x) for x in values[1:len(values)]}
        return(dict)

I had the same problem and later I realised that my app-routing.module.ts was inside a sub folder called app-routing. I moved this file directly under src and now it is working. (Now app-routing file has access to all the components)

private void btnChoose2_Click(object sender, EventArgs e)
{
  OpenFileDialog openfileDialog1 = new OpenFileDialog();
  if (openfileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
  {
    this.btnChoose2.Text = openfileDialog1.FileName;
    String filename = DialogResult.ToString();

    var excelApp = new Excel.Application();
    excelApp.Visible = true;
    excelApp.Workbooks.Open(btnChoose2.Text);
  }
}

After converting millis to seconds (by dividing by 1000), you can use / 60 to get the minutes value, and % 60 (remainder) to get the "seconds in minute" value.

long millis = .....;  // obtained from StopWatch
long minutes = (millis / 1000)  / 60;
int seconds = (int)((millis / 1000) % 60);

No, if a is true (in a or test), b will not be tested, as the result of the test will always be true, whatever is the value of the b expression.

Make a simple test:

if (true || ((String) null).equals("foobar")) {
    ...
}

will not throw a NullPointerException!

What just hit me, coming from Ruby, is that a so-called class method and a so-called instance method is just a function with semantic meaning applied to its first parameter, which is silently passed when the function is called as a method of an object (i.e. obj.meth()).

Normally that object must be an instance but the @classmethod method decorator changes the rules to pass a class. You can call a class method on an instance (it's just a function) - the first argument will be its class.

Because it's just a function, it can only be declared once in any given scope (i.e. class definition). If follows therefore, as a surprise to a Rubyist, that you can't have a class method and an instance method with the same name.

Consider this:

class Foo():
  def foo(x):
    print(x)

You can call foo on an instance

Foo().foo()
<__main__.Foo instance at 0x7f4dd3e3bc20>

But not on a class:

Foo.foo()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unbound method foo() must be called with Foo instance as first argument (got nothing instead)

Now add @classmethod:

class Foo():
  @classmethod
  def foo(x):
    print(x)

Calling on an instance now passes its class:

Foo().foo()
__main__.Foo

as does calling on a class:

Foo.foo()
__main__.Foo

It's only convention that dictates that we use self for that first argument on an instance method and cls on a class method. I used neither here to illustrate that it's just an argument. In Ruby, self is a keyword.

Contrast with Ruby:

class Foo
  def foo()
    puts "instance method #{self}"
  end
  def self.foo()
    puts "class method #{self}"
  end
end

Foo.foo()
class method Foo

Foo.new.foo()
instance method #<Foo:0x000000020fe018>

The Python class method is just a decorated function and you can use the same techniques to create your own decorators. A decorated method wraps the real method (in the case of @classmethod it passes the additional class argument). The underlying method is still there, hidden but still accessible.

footnote: I wrote this after a name clash between a class and instance method piqued my curiosity. I am far from a Python expert and would like comments if any of this is wrong.

I only want to cover second point of the question that is related to performance, because no body else has covered this. Select Into is a lot more faster than insert into, when it comes to tables with large datasets. I prefer select into when I have to read a very large table. insert into for a table with 10 million rows may take hours while select into will do this in minutes, and as for as losing indexes on new table is concerned you can recreate the indexes by query and can still save a lot more time when compared to insert into.

colon is using in for-each loop, Try this example,

import java.util.*;

class ForEachLoop
{
       public static void main(String args[])
       {`enter code here`
       Integer[] iray={1,2,3,4,5};
       String[] sray={"ENRIQUE IGLESIAS"};
       printME(iray);
       printME(sray);

       }
       public static void printME(Integer[] i)
       {           
                  for(Integer x:i)
                  {
                    System.out.println(x);
                  }
       }
       public static void printME(String[] i)
       {
                   for(String x:i)
                   {
                   System.out.println(x);
                   }
       }
}

Also, you can use <span ng-bind="hello"></span> instead of {{hello}}.

Full Outer join don't exist in mysql , you might need to use a combination of left and right join.

header("Location: route_to_main_page");

I've encountered this problem while having a custom 404 error handling file. Instead of throwing some html content it was suppose to redirect to the main page url. It worked well.

Then I used this as a skeleton for a next project, therefore not changing the "route_to_main_page" actually on the new project (different URL) became a "route_to_external_url" so any 404 errors within your code (missing css stylesheets, js libraries) would return the "Uncaught SyntaxError: Unexpected token <".

SQL Server by default uses the mdy date format and so the below works:

SELECT convert(datetime, '07/23/2009', 111)

and this does not work:

SELECT convert(datetime, '23/07/2009', 111)

I myself have been struggling to come up with a single query that can handle both date formats: mdy and dmy.

However, you should be ok with the third date format - ymd.

All the Answers are Quite great but if you want to use a single function ,this may work.

private bool validateTime(string dateInString)
{
    DateTime temp;
    if (DateTime.TryParse(dateInString, out temp))
    {
       return true;
    }
    return false;
}

If you are using jQuery UI, they already have a class the works just a charm add a <div> at the bottom inside the div that you want expand with height:auto; then add a class name ui-helper-clearfix or use this style attribute and add just like below:

<div style=" clear:both; overflow:hidden; height:1%; "></div>

add jQuery UI class to the clear div, not the div the you want to expand.

Resolution: the app is not a webapp because it doesn't have an embedded container (e.g. Tomcat) on the classpath. Adding one fixed it. If you are using Maven, then add this in pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

For Gradle (build.gradle) it looks like

dependencies {
    compile 'org.springframework.boot:spring-boot-starter-web'
}

For the current date activity and complete activity for previous 30 days use this, since the SYSDATE is variable in a day the previous 30th day will not have the whole data for that day.

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM mytable
WHERE create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND SYSDATE()

Suppose you want to rename key k3 to k4:

temp_dict = {'k1':'v1', 'k2':'v2', 'k3':'v3'}
temp_dict['k4']= temp_dict.pop('k3')

 SELECT * from
 (
 select m.*, rownum r
 from maps006 m
 )
 where r > 49 and r < 101

Your problem may be solved if you give your div a fixed width, as follows:

div#thing {
    position: absolute;
    top: 0px;
    z-index: 2;
    width:400px;
    margin-left:-200px;
    left:50%;
}

I had a similar issue. I was using jquery and jquery-ui. When I upgraded my versions, the close dialog image no longer appeared. My problem was that when I unzipped the js package that I downloaded, the directories did not have the execute permission.

So a quick chmod +x dir-name, and also for the sub-folders, did the trick. Without the execute permission on linux, apache cannot get into the folder.

I just put an index.html file in /htdocs and type in http://127.0.0.1/index.html - and up comes the html.

Add a folder "named Forum" and type in 127.0.0.1/forum/???.???

One more way assume branch1 - is branch with committed changes branch2 - is desirable branch

git fetch && git checkout branch1
git log

select commit ids that you need to move

git fetch && git checkout branch2
git cherry-pick commit_id_first..commit_id_last
git push

Now revert unpushed commits from initial branch

git fetch && git checkout branch1
git reset --soft HEAD~1

Setting CSS width to 1% or 100% of an element according to all specs I could find out is related to the parent. Although Blink Rendering Engine (Chrome) and Gecko (Firefox) at the moment of writing seems to handle that 1% or 100% (make a columns shrink or a column to fill available space) well, it is not guaranteed according to all CSS specifications I could find to render it properly.

One option is to replace table with CSS4 flex divs:

https://css-tricks.com/snippets/css/a-guide-to-flexbox/

That works in new browsers i.e. IE11+ see table at the bottom of the article.

The reason the solution you found on the internet is no working is because of the line that starts var colCount. The variable mytable only has two elements being <thead> and <tbody>. The var colCount line is looking for all the elements within mytable that are <tr>. The best thing you can do is give an id to your <thead> and <tbody> and then grab all the values based on that. Say you had <thead id='headers'> :

function write_headers_to_excel() 
{
  str="";

  var myTableHead = document.getElementById('headers');
  var rowCount = myTableHead.rows.length;
  var colCount = myTableHead.getElementsByTagName("tr")[0].getElementsByTagName("th").length; 

var ExcelApp = new ActiveXObject("Excel.Application");
var ExcelSheet = new ActiveXObject("Excel.Sheet");
ExcelSheet.Application.Visible = true;

for(var i=0; i<rowCount; i++) 
{   
    for(var j=0; j<colCount; j++) 
    {           
        str= myTableHead.getElementsByTagName("tr")[i].getElementsByTagName("th")[j].innerHTML;
        ExcelSheet.ActiveSheet.Cells(i+1,j+1).Value = str;
    }
}

}

and then do the same thing for the <tbody> tag.

EDIT: I would also highly recommend using jQuery. It would shorten this up to:

function write_to_excel() 
{
 var ExcelApp = new ActiveXObject("Excel.Application");
 var ExcelSheet = new ActiveXObject("Excel.Sheet");
 ExcelSheet.Application.Visible = true; 

  $('th, td').each(function(i){
    ExcelSheet.ActiveSheet.Cells(i+1,i+1).Value = this.innerHTML;
  });
}

Now, of course, this is going to give you some formatting issues but you can work out how you want it formatted in Excel.

EDIT: To answer your question about how to do this for n number of tables, the jQuery will do this already. To do it in raw Javascript, grab all the tables and then alter the function to be able to pass in the table as a parameter. For instance:

var tables = document.getElementsByTagName('table');
for(var i = 0; i < tables.length; i++)
{
  write_headers_to_excel(tables[i]);
  write_bodies_to_excel(tables[i]);
}

Then change the function write_headers_to_excel() to function write_headers_to_excel(table). Then change var myTableHead = document.getElementById('headers'); to var myTableHead = table.getElementsByTagName('thead')[0];. Same with your write_bodies_to_excel() or however you want to set that up.

Go to web.xml add <element> before <web-app> and close </element> after </web-app>

should be somethings like this

<?xml version="1.0" encoding="UTF-8"?>

<element>

<web-app>

....
</web-app>

</element>

You should use the *ngIf Directive

<div *ngIf="edited" class="alert alert-success box-msg" role="alert">
        <strong>List Saved!</strong> Your changes has been saved.
</div>


export class AppComponent implements OnInit{

  (...)
  public edited = false;
  (...)
  saveTodos(): void {
   //show box msg
   this.edited = true;
   //wait 3 Seconds and hide
   setTimeout(function() {
       this.edited = false;
       console.log(this.edited);
   }.bind(this), 3000);
  }
}

Update: you are missing the reference to the outer scope when you are inside the Timeout callback.

so add the .bind(this) like I added Above

Q : edited is a global variable. What would be your approach within a *ngFor-loop? – Blauhirn

A : I would add edit as a property to the object I am iterating over.

<div *ngFor="let obj of listOfObjects" *ngIf="obj.edited" class="alert alert-success box-msg" role="alert">
        <strong>List Saved!</strong> Your changes has been saved.
</div>


export class AppComponent implements OnInit{
   
  public listOfObjects = [
    {
       name : 'obj - 1',
       edit : false
    },
    {
       name : 'obj - 2',
       edit : false
    },
    {
       name : 'obj - 2',
       edit : false
    } 
  ];
  saveTodos(): void {
   //show box msg
   this.edited = true;
   //wait 3 Seconds and hide
   setTimeout(function() {
       this.edited = false;
       console.log(this.edited);
   }.bind(this), 3000);
  }
}

You may have found the answer for it already, but here is what I do.

I usually place this line at the beginning of my installation scripts:

if(!$PSScriptRoot){ $PSScriptRoot = Split-Path $MyInvocation.MyCommand.Path -Parent } #In case if $PSScriptRoot is empty (version of powershell V.2).  

Then I can use $PSScriptRoot variable as a location of the current script(path), like in the example bellow:

if(!$PSScriptRoot){ $PSScriptRoot = Split-Path $MyInvocation.MyCommand.Path -Parent } #In case if $PSScriptRoot is empty (version of powershell V.2).  

Try {
If (Test-Path 'C:\Program Files (x86)') {
    $ChromeInstallArgs= "/i", "$PSScriptRoot\googlechromestandaloneenterprise64_v.57.0.2987.110.msi", "/q", "/norestart", "/L*v `"C:\Windows\Logs\Google_Chrome_57.0.2987.110_Install_x64.log`""
    Start-Process -FilePath msiexec -ArgumentList $ChromeInstallArgs -Wait -ErrorAction Stop
    $Result= [System.Environment]::ExitCode
} Else {
    $ChromeInstallArgs= "/i", "$PSScriptRoot\googlechromestandaloneenterprise_v.57.0.2987.110.msi", "/q", "/norestart", "/L*v `"C:\Windows\Logs\Google_Chrome_57.0.2987.110_Install_x86.log`""
    Start-Process -FilePath msiexec -ArgumentList $ChromeInstallArgs -Wait -ErrorAction Stop
    $Result= [System.Environment]::ExitCode
    }

} ### End Try block


Catch  {
    $Result = [System.Environment]::Exitcode
    [System.Environment]::Exit($Result)
   }
[System.Environment]::Exit($Result)

In your case, you can replace

Start-process... line with

Invoke-Expression $PSScriptRoot\ScriptName.ps1

You can read more about $MYINVOCATION and $PSScriptRoot automatic variables on the Microsoft site: https://msdn.microsoft.com/en-us/powershell/reference/5.1/microsoft.powershell.core/about/about_automatic_variables

Here's a version that matches the output of ls -lh.

def human_size(num: int) -> str:
    base = 1
    for unit in ['B', 'K', 'M', 'G', 'T', 'P', 'E', 'Z', 'Y']:
        n = num / base
        if n < 9.95 and unit != 'B':
            # Less than 10 then keep 1 decimal place
            value = "{:.1f}{}".format(n, unit)
            return value
        if round(n) < 1000:
            # Less than 4 digits so use this
            value = "{}{}".format(round(n), unit)
            return value
        base *= 1024
    value = "{}{}".format(round(n), unit)
    return value

A pure solution without jQuery:

Javascript (Head)

function chbg(color) {
    document.getElementById('b').style.backgroundColor = color;
}   

HTML (Body)

<div id="a" onmouseover="chbg('red')" onmouseout="chbg('white')">This is element a</div>
<div id="b">This is element b</div>

Plase check application pool. if it is stoped. restart it.

Alternatively, you may also use the CSS3 Flexible Box Model. It's a great way to create flexible layouts that can also be applied to center content like so:

#parent {
    -webkit-box-align:center;
    -webkit-box-pack:center;
    display:-webkit-box;
}

Most people do not read the comments so to summarize (Thanks to @Industrial-antidepressant and @wrecker):

As suggested in a bug ticket you should try the following:

1. Close Android Studio
2. go to android-studio/plugins/gradle/lib
3. Delete (or better move them somewhere to have a backup) all gradle-*-1.8 files
4. Start Android Studio again and rebuild/refresh.

It should work. Make sure to star the above bug ticket to get informed.

Little tip: Try the new compile setting Settings -> Compiler -> Gradle and activate the third in-process build for a speed up. Depending on your project setting you might want to select the first one as well. With that my project build time reduced to 2-4 seconds (before 20+ seconds).

For windows user, type netstat -anin command prompt to see ports that are listening, this may come handy.

If you have Node.js 4.4+, take a look at reqclient, it allows you to make calls and log the requests in cURL style, so you can easily check and reproduce the calls outside the application.

Returns Promise objects instead of pass simple callbacks, so you can handle the result in a more "fashion" way, chain the result easily, and handle errors in a standard way. Also removes a lot of boilerplate configurations on each request: base URL, time out, content type format, default headers, parameters and query binding in the URL, and basic cache features.

This is an example of how to initialize it, make a call and log the operation with curl style:

var RequestClient = require("reqclient").RequestClient;
var client = new RequestClient({
    baseUrl:"http://baseurl.com/api/", debugRequest:true, debugResponse:true});
client.post("client/orders", {"client": 1234, "ref_id": "A987"},{"x-token": "AFF01XX"});

This will log in the console...

[Requesting client/orders]-> -X POST http://baseurl.com/api/client/orders -d '{"client": 1234, "ref_id": "A987"}' -H '{"x-token": "AFF01XX"}' -H Content-Type:application/json

And when the response is returned ...

[Response   client/orders]<- Status 200 - {"orderId": 1320934}

This is an example of how to handle the response with the promise object:

client.get("reports/clients")
  .then(function(response) {
    // Do something with the result
  }).catch(console.error);  // In case of error ...

Of course, it can be installed with: npm install reqclient.

See What is the maximum length of a URL in different browsers?

The length of the url can't be changed in PHP. The linked question is about the URL size limit, you will find what you want.

I think that the RoundingMode you are looking for is ROUND_HALF_EVEN. From the javadoc:

Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for ROUND_HALF_UP if the digit to the left of the discarded fraction is odd; behaves as for ROUND_HALF_DOWN if it's even. Note that this is the rounding mode that minimizes cumulative error when applied repeatedly over a sequence of calculations.

Here is a quick test case:

BigDecimal a = new BigDecimal("10.12345");
BigDecimal b = new BigDecimal("10.12556");

a = a.setScale(2, BigDecimal.ROUND_HALF_EVEN);
b = b.setScale(2, BigDecimal.ROUND_HALF_EVEN);

System.out.println(a);
System.out.println(b);

Correctly prints:

10.12
10.13

UPDATE:

setScale(int, int) has not been recommended since Java 1.5, when enums were first introduced, and was finally deprecated in Java 9. You should now use setScale(int, RoundingMode) e.g:

setScale(2, RoundingMode.HALF_EVEN)

I used the below JavaScript code and it works...

var clickButton = document.getElementById("<%= btnClearSession.ClientID %>");
clickButton.click();

The info inside the <script> tag is then processed inside it to access other parts. If you want to change the text inside another paragraph, then first give the paragraph an id, then set a variable to it using getElementById([id]) to access it ([id] means the id you gave the paragraph). Next, use the innerHTML built-in variable with whatever your variable was called and a '.' (dot) to show that it is based on the paragraph. You can set it to whatever you want, but be aware that to set a paragraph to a tag (<...>), then you have to still put it in speech marks.

Example:

<!DOCTYPE html>_x000D_
<html>_x000D_
    <body>_x000D_
        <!--\|/id here-->_x000D_
        <p id="myText"></p>_x000D_
        <p id="myTextTag"></p>_x000D_
        <script>_x000D_
            <!--Here we retrieve the text and show what we want to write..._x000D_
            var text = document.getElementById("myText");_x000D_
            var tag = document.getElementById("myTextTag");_x000D_
            var toWrite = "Hello"_x000D_
            var toWriteTag = "<a href='https://stackoverflow.com'>Stack Overflow</a>"_x000D_
            <!--...and here we are actually affecting the text.-->_x000D_
            text.innerHTML = toWrite_x000D_
            tag.innerHTML = toWriteTag_x000D_
        </script>_x000D_
    <body>_x000D_
<html>

Basically, tree conflicts arise if there is some restructure in the folder structure on the branch. You need to delete the conflict folder and use svn clean once. Hope this solves your conflict.

Looks like you need something along the lines of this: Git checkout based on date

In other words, you use rev-list to find the commit and then use checkout to actually get it.

If you don't want to lose your staged changes, the easiest thing would be to create a new branch and commit them to that branch. You can always switch back and forth between branches.

Edit: The link is down, so here's the command:

git checkout `git rev-list -n 1 --before="2009-07-27 13:37" master`

Two important CSS properties to set for full height pages are these:

1. Allow the body to grow as high as the content in it requires.

   html { height: 100%; }
   

2. Force the body not to get any smaller than then window height.

   body { min-height: 100%; }
   

What you do with your gird is irrelevant as long as you use fractions or percentages you should be safe in all cases.

Have a look at this common dashboard layout.

As MRA said, you shouldn't try to dodge a 429 Too Many Requests but instead handle it accordingly. You have several options depending on your use-case:

1) Sleep your process. The server usually includes a Retry-after header in the response with the number of seconds you are supposed to wait before retrying. Keep in mind that sleeping a process might cause problems, e.g. in a task queue, where you should instead retry the task at a later time to free up the worker for other things.

2) Exponential backoff. If the server does not tell you how long to wait, you can retry your request using increasing pauses in between. The popular task queue Celery has this feature built right-in.

3) Token bucket. This technique is useful if you know in advance how many requests you are able to make in a given time. Each time you access the API you first fetch a token from the bucket. The bucket is refilled at a constant rate. If the bucket is empty, you know you'll have to wait before hitting the API again. Token buckets are usually implemented on the other end (the API) but you can also use them as a proxy to avoid ever getting a 429 Too Many Requests. Celery's rate_limit feature uses a token bucket algorithm.

Here is an example of a Python/Celery app using exponential backoff and rate-limiting/token bucket:

class TooManyRequests(Exception):
"""Too many requests"""

@task(
   rate_limit='10/s',
   autoretry_for=(ConnectTimeout, TooManyRequests,),
   retry_backoff=True)
def api(*args, **kwargs):
  r = requests.get('placeholder-external-api')

  if r.status_code == 429:
    raise TooManyRequests()

int g[] = {9,8};

This declares an object of type int[2], and initializes its elements to {9,8}

int (*j) = g;

This declares an object of type int *, and initializes it with a pointer to the first element of g.

The fact that the second declaration initializes j with something other than g is pretty strange. C and C++ just have these weird rules about arrays, and this is one of them. Here the expression g is implicitly converted from an lvalue referring to the object g into an rvalue of type int* that points at the first element of g.

This conversion happens in several places. In fact it occurs when you do g[0]. The array index operator doesn't actually work on arrays, only on pointers. So the statement int x = j[0]; works because g[0] happens to do that same implicit conversion that was done when j was initialized.

A pointer to an array is declared like this

int (*k)[2];

and you're exactly right about how this would be used

int x = (*k)[0];

(note how "declaration follows use", i.e. the syntax for declaring a variable of a type mimics the syntax for using a variable of that type.)

However one doesn't typically use a pointer to an array. The whole purpose of the special rules around arrays is so that you can use a pointer to an array element as though it were an array. So idiomatic C generally doesn't care that arrays and pointers aren't the same thing, and the rules prevent you from doing much of anything useful directly with arrays. (for example you can't copy an array like: int g[2] = {1,2}; int h[2]; h = g;)

Examples:

void foo(int c[10]); // looks like we're taking an array by value.
// Wrong, the parameter type is 'adjusted' to be int*

int bar[3] = {1,2};
foo(bar); // compile error due to wrong types (int[3] vs. int[10])?
// No, compiles fine but you'll probably get undefined behavior at runtime

// if you want type checking, you can pass arrays by reference (or just use std::array):
void foo2(int (&c)[10]); // paramater type isn't 'adjusted'
foo2(bar); // compiler error, cannot convert int[3] to int (&)[10]

int baz()[10]; // returning an array by value?
// No, return types are prohibited from being an array.

int g[2] = {1,2};
int h[2] = g; // initializing the array? No, initializing an array requires {} syntax
h = g; // copying an array? No, assigning to arrays is prohibited

Because arrays are so inconsistent with the other types in C and C++ you should just avoid them. C++ has std::array that is much more consistent and you should use it when you need statically sized arrays. If you need dynamically sized arrays your first option is std::vector.

My favourite of the below is var_dump, which when called as:

var_dump("%d", count);

produces output like:

patch.c:150:main(): count = 0

Credit to @"Jonathan Leffler". All are C89-happy:

Code

#define DEBUG 1
#include <stdarg.h>
#include <stdio.h>
void debug_vprintf(const char *fmt, ...)
{
    va_list args;
    va_start(args, fmt);
    vfprintf(stderr, fmt, args);
    va_end(args);
}

/* Call as: (DOUBLE PARENTHESES ARE MANDATORY) */
/* var_debug(("outfd = %d, somefailed = %d\n", outfd, somefailed)); */
#define var_debug(x) do { if (DEBUG) { debug_vprintf ("%s:%d:%s(): ", \

/* var_dump("%s" variable_name); */
#define var_dump(fmt, var) do { if (DEBUG) { debug_vprintf ("%s:%d:%s(): ", \
    __FILE__,  __LINE__, __func__); debug_vprintf ("%s = " fmt, #var, var); }} while (0)

#define DEBUG_HERE do { if (DEBUG) { debug_vprintf ("%s:%d:%s(): HERE\n", \
    __FILE__,  __LINE__, __func__); }} while (0)

the htons() function converts values between host and network byte orders. There is a difference between big-endian and little-endian and network byte order depending on your machine and network protocol in use.

Just enable the "Build Active Architecture Only" option

in PROJECT >> Build Settings >> Build Active Architecture Only >> Yes

remember to check if they are also enabled in each target

If you have a List<List<int>> k you can do

List<int> flatList= k.SelectMany( v => v).ToList();

This library is the easiest and quickest solution to the problem.

To help newbies navigate through the manual fog, it might be helpful to see the [[ ... ]] notation as a collapsing function - in other words, it is when you just want to 'get the data' from a named vector, list or data frame. It is good to do this if you want to use data from these objects for calculations. These simple examples will illustrate.

(x <- c(x=1, y=2)); x[1]; x[[1]]
(x <- list(x=1, y=2, z=3)); x[1]; x[[1]]
(x <- data.frame(x=1, y=2, z=3)); x[1]; x[[1]]

So from the third example:

> 2 * x[1]
  x
1 2
> 2 * x[[1]]
[1] 2

I just want to expand on queen3's suggestion, applying the following does the trick:

editoptions: { 
              dataInit: function(element) { 
                          $(element).attr("readonly", "readonly"); 
                        } 
             }

Scenario #1:

• Field must be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
        {  name:'providerUserId',
               index:'providerUserId', 
               width:100,editable:true, 
               editrules:{required:true}, 
               editoptions:{ 
                            dataInit: function(element) { 
                                  jq(element).attr("readonly", "readonly"); 
                             } 
                           }
            },
],

The providerUserId is visible in the grid and visible when editing the form. But you cannot edit the contents.

Scenario #2:

• Field must not be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
           {name:'providerUserId',
            index:'providerUserId', 
            width:100,editable:true, 
            editrules:{
                         required:true, 
                         edithidden:true
                      },
            hidden:true, 
            editoptions:{ 
                  dataInit: function(element) {                     
                             jq(element).attr("readonly", "readonly"); 
                          } 
                     }
         },
        ]

Notice in both instances I'm using jq to reference jquery, instead of the usual $. In my HTML I have the following script to modify the variable used by jQuery:

<script type="text/javascript">
    var jq = jQuery.noConflict();
</script>

1. Create a .gitignore file, so to do that, you just create any blank .txt file.

2. Then you have to change its name writing the following line on the cmd (where git.txt is the name of the file you've just created):

   rename git.txt .gitignore

3. Then you can open the file and write all the untracked files you want to ignore for good. For example, mine looks like this:

```

OS junk files
[Tt]humbs.db
*.DS_Store

#Visual Studio files
*.[Oo]bj
*.user
*.aps
*.pch
*.vspscc
*.vssscc
*_i.c
*_p.c
*.ncb
*.suo
*.tlb
*.tlh
*.bak
*.[Cc]ache
*.ilk
*.log
*.lib
*.sbr
*.sdf
*.pyc
*.xml

#Tooling

[Tt]est[Rr]esult*

#Project files

#Subversion files

# Office Temp Files
~$*

There's a whole collection of useful .gitignore files by GitHub

4. Once you have this, you need to add it to your git repository just like any other file, only it has to be in the root of the repository.

5. Then in your terminal you have to write the following line:

   git config --global core.excludesfile ~/.gitignore_global

From oficial doc:

You can also create a global .gitignore file, which is a list of rules for ignoring files in every Git repository on your computer. For example, you might create the file at ~/.gitignore_global and add some rules to it.

Open Terminal. Run the following command in your terminal: git config --global core.excludesfile ~/.gitignore_global

If the respository already exists then you have to run these commands:

git rm -r --cached .
git add .
git commit -m ".gitignore is now working"

If the step 2 doesn´t work then you should write the hole route of the files that you would like to add.

You can also try this:

scp -r /cygdrive/c/desktop/myfolder/deployments/ user@host:/path/to/whereyouwant/thefile

It turns out that if you don't specify the Model to the View method within your controller, it doesn't create a object for you with the default values.

[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Create()
{
  // Loads default values
  Instructor i = new Instructor();
  return View("Create", i);
}

[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Create()
{
  // Does not load default values from instructor
  return View("Create");
}

To add yonix’s comment as an answer, the old fb://page/… URL no longer works. Apparently it was replaced by fb://profile/…, even though a page is not a profile.

The runtime jre was set to jre 6 instead of jre 7 in the build configuration window.

As many others pointed out if you are trying to add a new element at the end of list then something like, array[array.length-1]=x; should do. But this will replace the existing element.

For something like continuous addition to the array. You can keep track of the index and go on adding elements till you reach end and have the function that does the addition return you the next index, which in turn will tell you how many more elements can fit in the array.

Of course in both the cases the size of array will be predefined. Vector can be your other option since you do not want arraylist, which will allow you all the same features and functions and additionally will take care of incrementing the size.

Coming to the part where you want StringBuffer to array. I believe what you are looking for is the getChars(int srcBegin, int srcEnd,char[] dst,int dstBegin) method. Look into it that might solve your doubts. Again I would like to point out that after managing to get an array out of it, you can still only replace the last existing element(character in this case).

The best looking way I've found to go through a cursor is the following:

Cursor cursor;
... //fill the cursor here

for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) {
    // do what you need with the cursor here
}

Don't forget to close the cursor afterwards

EDIT: The given solution is great if you ever need to iterate a cursor that you are not responsible of. A good example would be, if you are taking a cursor as argument in a method, and you need to scan the cursor for a given value, without having to worry about the cursor's current position.

This can be done using HTML5, but will only work in browsers that support it. Here's an example.

Bear in mind you'll need an alternative method for browsers that don't support this. I've had a lot of success with this plugin, which takes a lot of the work out of your hands.

If you use PHP on Linux, you may try the following to read text for example between 74th and 159th lines:

$text = shell_exec("sed -n '74,159p' path/to/file.log");

This solution is good if your file is large.

Enter the following in the terminal:

$/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app/Contents/MacOS/iPhone\ Simulator -SimulateApplication path/to/your/file/projectname.app/projectname

Access 2007 can lose the CurrentDb: see http://support.microsoft.com/kb/167173, so in the event of getting "Object Invalid or no longer set" with the examples, use:

Dim db as Database
Dim rs As DAO.Recordset
Set db = CurrentDB
Set rs = db.OpenRecordset("SELECT * FROM myTable")

If it's a problem with the not selector, you can set all of them and override the last one

li:after
{
  content: ' |';
}
li:last-child:after
{
  content: '';
}

or if you can use before, no need for last-child

li+li:before
{
  content: '| ';
}

This will work if your route looks like this: localhost:8888/p?tagid=1234

var tagId = req.query.tagid;
console.log(tagId); // outputs: 1234
console.log(req.query.tagid); // outputs: 1234

Otherwise use the following code if your route looks like this: localhost:8888/p/1234

var tagId = req.params.tagid;
console.log(tagId); // outputs: 1234
console.log(req.params.tagid); // outputs: 1234

/sbin/ip route|awk '/default/ { print $3 }'

As @MichaelNeale noticed, there is no sense to use this method in Dockerfile (except when we need this IP during build time only), because this IP will be hardcoded during build time.

I created a 2 prototype to handle this for me, one for a number, and one for a String.

// This is a safety check to make sure the prototype is not already defined.
Function.prototype.method = function (name, func) {
    if (!this.prototype[name]) {
        this.prototype[name] = func;
        return this;
    }
};

// returns the int value or -1 by default if it fails
Number.method('tryParseInt', function (defaultValue) {
    return parseInt(this) == this ? parseInt(this) : (defaultValue === undefined ? -1 : defaultValue);
});

// returns the int value or -1 by default if it fails
String.method('tryParseInt', function (defaultValue) {
    return parseInt(this) == this ? parseInt(this) : (defaultValue === undefined ? -1 : defaultValue);
});

If you dont want to use the safety check, use

String.prototype.tryParseInt = function(){
    /*Method body here*/
};
Number.prototype.tryParseInt = function(){
     /*Method body here*/
};

Example usage:

var test = 1;
console.log(test.tryParseInt()); // returns 1

var test2 = '1';
console.log(test2.tryParseInt()); // returns 1

var test3 = '1a';
console.log(test3.tryParseInt()); // returns -1 as that is the default

var test4 = '1a';
console.log(test4.tryParseInt(0));// returns 0, the specified default value

I also had the same issue.Make a directory in dbpath.In my case there wasn't a directory in /data/db .So i created one.Now its working.Make sure to give permission to that directory.

sed 's.\\./.g'

There's no reason to use / as the separator in sed. But if you really wanted to:

sed 's/\\/\//g'

A couple of scenarios might help illustrate the purpose of access and refresh tokens and the engineering trade-offs in designing an oauth2 (or any other auth) system:

Web app scenario

In the web app scenario you have a couple of options:

1. if you have your own session management, store both the access_token and refresh_token against your session id in session state on your session state service. When a page is requested by the user that requires you to access the resource use the access_token and if the access_token has expired use the refresh_token to get the new one.

Let's imagine that someone manages to hijack your session. The only thing that is possible is to request your pages.

2. if you don't have session management, put the access_token in a cookie and use that as a session. Then, whenever the user requests pages from your web server send up the access_token. Your app server could refresh the access_token if need be.

Comparing 1 and 2:

In 1, access_token and refresh_token only travel over the wire on the way between the authorzation server (google in your case) and your app server. This would be done on a secure channel. A hacker could hijack the session but they would only be able to interact with your web app. In 2, the hacker could take the access_token away and form their own requests to the resources that the user has granted access to. Even if the hacker gets a hold of the access_token they will only have a short window in which they can access the resources.

Either way the refresh_token and clientid/secret are only known to the server making it impossible from the web browser to obtain long term access.

Let's imagine you are implementing oauth2 and set a long timeout on the access token:

In 1) There's not much difference here between a short and long access token since it's hidden in the app server. In 2) someone could get the access_token in the browser and then use it to directly access the user's resources for a long time.

Mobile scenario

On the mobile, there are a couple of scenarios that I know of:

1. Store clientid/secret on the device and have the device orchestrate obtaining access to the user's resources.

2. Use a backend app server to hold the clientid/secret and have it do the orchestration. Use the access_token as a kind of session key and pass it between the client and the app server.

Comparing 1 and 2

In 1) Once you have clientid/secret on the device they aren't secret any more. Anyone can decompile and then start acting as though they are you, with the permission of the user of course. The access_token and refresh_token are also in memory and could be accessed on a compromised device which means someone could act as your app without the user giving their credentials. In this scenario the length of the access_token makes no difference to the hackability since refresh_token is in the same place as access_token. In 2) the clientid/secret nor the refresh token are compromised. Here the length of the access_token expiry determines how long a hacker could access the users resources, should they get hold of it.

Expiry lengths

Here it depends upon what you're securing with your auth system as to how long your access_token expiry should be. If it's something particularly valuable to the user it should be short. Something less valuable, it can be longer.

Some people like google don't expire the refresh_token. Some like stackflow do. The decision on the expiry is a trade-off between user ease and security. The length of the refresh token is related to the user return length, i.e. set the refresh to how often the user returns to your app. If the refresh token doesn't expire the only way they are revoked is with an explicit revoke. Normally, a log on wouldn't revoke.

Hope that rather length post is useful.

I know this question has been answered but the answers i found here didn't work for my scenario ( or for Windows ).

I am using windows 10 laptop with PHP 7.2 in Xampp v3.2.4.

$command = 'php Cron.php send_email "'. $id .'"';
if ( substr(php_uname(), 0, 7) == "Windows" )
{
    //windows
    pclose(popen("start /B " . $command . " 1> temp/update_log 2>&1 &", "r"));
}
else
{
    //linux
    shell_exec( $command . " > /dev/null 2>&1 &" );
}

This worked perfectly for me.

I hope it will help someone with windows. Cheers.

Why not use PHP! It's all server side:

<?php print file_get_contents("http://foo.com")?>

If you own both sites, you may need to ok this transaction with full declaration of headers at the server end. Works beautifully.

Do you want the JDK or the JRE? Anyways, I had this problem too, a few weeks ago. I followed the instructions here and it worked:

http://www.backtrack-linux.org/wiki/index.php/Java_Install

NOTE: Before installing Java make sure you kill Firefox.

root@bt:~# killall -9 /opt/firefox/firefox-bin

You can download java from the official website. (Download tar.gz version)

We first create the directory and place java there:

root@bt:~# mkdir /opt/java

root@bt:~# mv -f jre1.7.0_05/ /opt/java/

Final changes.

root@bt:~# update-alternatives --install /usr/bin/java java /opt/java/jre1.7.0_05/bin/java 1

root@bt:~# update-alternatives --set java /opt/java/jre1.7.0_05/bin/java

root@bt:~# export JAVA_HOME="/opt/java/jre1.7.0_05"

Adding the plugin to Firefox.

For Java 7 (32 bit)

root@bt:~# ln -sf $JAVA_HOME/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/

For Java 8 (64 bit)

root@bt:~# ln -sf $JAVA_HOME/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/

Testing the plugin.

root@bt:~# firefox http://java.com/en/download/testjava.jsp

In my case, I was making a Firefox Add-on and forgot to add the permission for the url/domain I was trying to ajax, hope this saves someone a lot of time.

I'm not sure exactly why I was getting the error, but pip3 uninstall numpy then pip3 install numpy resolved the issue for me.

PHP and MySQL have their own default timezone configurations. You should synchronize time between your data base and web application, otherwise you could run some issues.

Read this tutorial: How To Synchronize Your PHP and MySQL Timezones

Lets say we have a script in "c:\script.py" that contain :

result = open("index.html","r")
print(result.read())

Lets say that the index.html file is also in the same directory "c:\index.html" when i execute the script from cmd (or shell)

C:\Users\Amine>python c:\script.py

You will get error:

FileNotFoundError: [Errno 2] No such file or directory: 'index.html'

And that because "index.html" is not in working directory which is "C:\Users\Amine>". so in order to make it work you have to change the working directory

C:\python script.py

'<html><head></head><body></body></html>'

This is why is it preferable to use absolute path.

Try using the passive command before using ls.

From FTP client, to check if the FTP server supports passive mode, after login, type quote PASV.

Following are connection examples to a vsftpd server with passive mode on and off

vsftpd with pasv_enable=NO:

# ftp localhost
Connected to localhost.localdomain.
220 (vsFTPd 2.3.5)
Name (localhost:john): anonymous
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> quote PASV
550 Permission denied.
ftp> 

vsftpd with pasv_enable=YES:

# ftp localhost
Connected to localhost.localdomain.
220 (vsFTPd 2.3.5)
Name (localhost:john): anonymous
331 Please specify the password.

This is more of an IDE feature than a language feature. Netbeans allows you to define your own folding definitions using the following definition:

// <editor-fold defaultstate="collapsed" desc="user-description">
  ...any code...
// </editor-fold>

As noted in the article, this may be supported by other editors too, but there are no guarantees.

Due to my reputation points being less than 50 I could not comment on or vote for E Coder's answer above. This is the best way to do it so you don't have to use the group by as I had a similar issue.
By doing SUM((coalesce(VALUE1 ,0)) + (coalesce(VALUE2 ,0))) as Total this will get you the number you want but also rid you of any error for not performing a Group By. This was my query and gave me a total count and total amount for the each dealer and then gave me a subtotal for Quality and Risky dealer loans.

SELECT 
    DISTINCT STEP1.DEALER_NBR
    ,COUNT(*) AS DLR_TOT_CNT
    ,SUM((COALESCE(DLR_QLTY,0))+(COALESCE(DLR_RISKY,0))) AS DLR_TOT_AMT
    ,COUNT(STEP1.DLR_QLTY) AS DLR_QLTY_CNT
    ,SUM(STEP1.DLR_QLTY) AS DLR_QLTY_AMT
    ,COUNT(STEP1.DLR_RISKY) AS DLR_RISKY_CNT
    ,SUM(STEP1.DLR_RISKY) AS DLR_RISKY_AMT
    FROM STEP1
    WHERE DLR_QLTY IS NOT NULL OR DLR_RISKY IS NOT NULL
        GROUP BY STEP1.DEALER_NBR

Have you installed Windows Identity Foundation and the companion WIF SDK?

If you have a look at the source: github/v8, it seems that you try to reserve a very big object.According to my experience it happens if you try to parse a huge JSON object, but when I try to parse your output with JSON and node0.11.13, it just works fine.

You don't need more --stack-size, you need more memory: --max_new_space_size and/or --max_old_space_size.

The only hint I can give you beside that is trying another JSON-parser and/or try to change the input format to JSON line instead of JSON only.

For those using the Google API Client Library for PHP and seeking offline access and refresh tokens beware as of the time of this writing the docs are showing incorrect examples.

currently it's showing:

$client = new Google_Client();
$client->setAuthConfig('client_secret.json');
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');
// offline access will give you both an access and refresh token so that
// your app can refresh the access token without user interaction.
$client->setAccessType('offline');
// Using "consent" ensures that your application always receives a refresh token.
// If you are not using offline access, you can omit this.
$client->setApprovalPrompt("consent");
$client->setIncludeGrantedScopes(true);   // incremental auth

source: https://developers.google.com/identity/protocols/OAuth2WebServer#offline

All of this works great - except ONE piece

$client->setApprovalPrompt("consent");

After a bit of reasoning I changed this line to the following and EVERYTHING WORKED

$client->setPrompt("consent");

It makes sense since using the HTTP requests it was changed from approval_prompt=force to prompt=consent. So changing the setter method from setApprovalPrompt to setPrompt follows natural convention - BUT IT'S NOT IN THE DOCS!!! That I found at least.

The best way to go to the last line of the file is with G. This will move the cursor to the last line of the file.

The best way to go to the last column in the line is with $. This will move the cursor to the last column of the current line.

So just by doing G$ you get to the end of the file and the last line.

And if you want to enter insert mode at the end of the file then you just do GA. By doing this you go to the last line of the file, and enter insert mode by appending to the last column. :)

I think the easiest workaround would be to use 'select' with 'multiple' specified:

<select ng-model="selectedfruit" multiple ng-options="v for v in fruit"></select>

Otherwise, I think you'll have to process the list to construct the list (by $watch()ing the model array bind with checkboxes).

Technically, putting null or 0, or just some random value there works (since you are not using the return value). However, why are you using this construct instead of the if construct? It is less obvious what you are trying to do when you write code this way, as you may confuse people with the no-op (null in your case).

You just needed to cast the unsigned char into a char as the string class doesn't have a constructor that accepts unsigned char:

unsigned char* uc;
std::string s( reinterpret_cast< char const* >(uc) ) ;

However, you will need to use the length argument in the constructor if your byte array contains nulls, as if you don't, only part of the array will end up in the string (the array up to the first null)

size_t len;
unsigned char* uc;
std::string s( reinterpret_cast<char const*>(uc), len ) ;

Use sha1 to generate checksum:

sha1 [FILENAME1]
sha1 [FILENAME2]

I wrote a shellscript that solves this problem for multiple websites: https://github.com/eduardschaeli/wget-image-scraper

(Scrapes images from a list of urls with wget)

An abbreviated version of your code worked for me,

class Remote: NSObject {

    var data = NSMutableData()

    func connect(query:NSString) {
        var url =  NSURL.URLWithString("http://www.google.com")
        var request = NSURLRequest(URL: url)
        var conn = NSURLConnection(request: request, delegate: self, startImmediately: true)
    }


     func connection(didReceiveResponse: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
        println("didReceiveResponse")
    }

    func connection(connection: NSURLConnection!, didReceiveData conData: NSData!) {
        self.data.appendData(conData)
    }

    func connectionDidFinishLoading(connection: NSURLConnection!) {
        println(self.data)
    }


    deinit {
        println("deiniting")
    }
}

This is the code I used in the calling class,

class ViewController: UIViewController {

    var remote = Remote()


    @IBAction func downloadTest(sender : UIButton) {
        remote.connect("/apis")
    }

}

You didn't specify in your question where you had this code,

var remote = Remote()
remote.connect("/apis")

If var is a local variable, then the Remote class will be deallocated right after the connect(query:NSString) method finishes, but before the data returns. As you can see by my code, I usually implement reinit (or dealloc up to now) just to make sure when my instances go away. You should add that to your Remote class to see if that's your problem.

This is a presumably slightly less optimized version of the C code from here which was sourced from this page.

My C++ version uses a std::vector<std::pair<double, double>> and two doubles as an x and y. The logic should be exactly the same as the original C code, but I find mine easier to read. I can't speak for the performance.

bool point_in_poly(std::vector<std::pair<double, double>>& verts, double point_x, double point_y)
{
    bool in_poly = false;
    auto num_verts = verts.size();
    for (int i = 0, j = num_verts - 1; i < num_verts; j = i++) {
        double x1 = verts[i].first;
        double y1 = verts[i].second;
        double x2 = verts[j].first;
        double y2 = verts[j].second;

        if (((y1 > point_y) != (y2 > point_y)) &&
            (point_x < (x2 - x1) * (point_y - y1) / (y2 - y1) + x1))
            in_poly = !in_poly;
    }
    return in_poly;
}

The original C code is

int pnpoly(int nvert, float *vertx, float *verty, float testx, float testy)
{
  int i, j, c = 0;
  for (i = 0, j = nvert-1; i < nvert; j = i++) {
    if ( ((verty[i]>testy) != (verty[j]>testy)) &&
     (testx < (vertx[j]-vertx[i]) * (testy-verty[i]) / (verty[j]-verty[i]) + vertx[i]) )
       c = !c;
  }
  return c;
}

Perhaps I am very late, but as of now there's another way to use it using the jquery ui slider.

Much of the time when you ask for a dynamic object, you get an ExpandoObject (not in the question's anonymous-but-statically-typed example above, but you mention JavaScript and my chosen JSON parser JsonFx, for one, generates ExpandoObjects).

If your dynamic is in fact an ExpandoObject, you can avoid reflection by casting it to IDictionary, as described at http://msdn.microsoft.com/en-gb/library/system.dynamic.expandoobject.aspx.

Once you've cast to IDictionary, you have access to useful methods like .Item and .ContainsKey

Just for others to see:

someString.replaceAll("([^\\p{L}\\p{N}])", " ");

will remove any non-letter and non-number unicode characters.

The value attribute is used to determine the rendered label of a submit input.

<input type="submit" class="like" value="Like" />

Note that if the control is successful (this one won't be as it has no name) this will also be the submitted value for it.

To have a different submitted value and label you need to use a button element, in which the textNode inside the element determines the label. You can include other elements (including <img> here).

<button type="submit" class="like" name="foo" value="bar">Like</button>

Note that support for <button> is dodgy in older versions of Internet Explorer.
