One of the goals of compilers is to rule out classes of errors. Some unreachable code is there by accident, it's nice that javac rules out that class of error at compile time.

For every rule that catches erroneous code, someone will want the compiler to accept it because they know what they're doing. That's the penalty of compiler checking, and getting the balance right is one of the tricker points of language design. Even with the strictest checking there's still an infinite number of programs that can be written, so things can't be that bad.

From oracle documentation about CountDownLatch:

A synchronization aid that allows one or more threads to wait until a set of operations being performed in other threads completes.

A CountDownLatch is initialized with a given count. The await methods block until the current count reaches zero due to invocations of the countDown() method, after which all waiting threads are released and any subsequent invocations of await return immediately. This is a one-shot phenomenon -- the count cannot be reset.

A CountDownLatch is a versatile synchronization tool and can be used for a number of purposes.

A CountDownLatch initialized with a count of one serves as a simple on/off latch, or gate: all threads invoking await wait at the gate until it is opened by a thread invoking countDown().

A CountDownLatch initialized to N can be used to make one thread wait until N threads have completed some action, or some action has been completed N times.

public void await()
           throws InterruptedException

Causes the current thread to wait until the latch has counted down to zero, unless the thread is interrupted.

If the current count is zero then this method returns immediately.

public void countDown()

Decrements the count of the latch, releasing all waiting threads if the count reaches zero.

If the current count is greater than zero then it is decremented. If the new count is zero then all waiting threads are re-enabled for thread scheduling purposes.

Explanation of your example.

1. You have set count as 3 for latch variable

   CountDownLatch latch = new CountDownLatch(3);
   

2. You have passed this shared latch to Worker thread : Processor

3. Three Runnable instances of Processor have been submitted to ExecutorService executor

4. Main thread ( App ) is waiting for count to become zero with below statement

    latch.await();  
   

5. Processor thread sleeps for 3 seconds and then it decrements count value with latch.countDown()

6. First Process instance will change latch count as 2 after it's completion due to latch.countDown().

7. Second Process instance will change latch count as 1 after it's completion due to latch.countDown().

8. Third Process instance will change latch count as 0 after it's completion due to latch.countDown().

9. Zero count on latch causes main thread App to come out from await

10. App program prints this output now : Completed

The uriVariables are also expanded in the query string. For example, the following call will expand values for both, account and name:

restTemplate.exchange("http://my-rest-url.org/rest/account/{account}?name={name}",
    HttpMethod.GET,
    httpEntity,
    clazz,
    "my-account",
    "my-name"
);

so the actual request url will be

http://my-rest-url.org/rest/account/my-account?name=my-name

Look at HierarchicalUriComponents.expandInternal(UriTemplateVariables) for more details. Version of Spring is 3.1.3.

Don't like any of those solutions.

this is how i do it:

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='" 
            . sqlEsc($somename) . "' ;";

then i use my own sqlEsc function:

function sqlEsc($val) 
{
    global $mysqli;
    return mysqli_real_escape_string($mysqli, $val);
}

That's it.

Put simply, an lvalue is something that can appear on the left-hand side of an assignment, typically a variable or array element.

So if you define int *p, then p is an lvalue. p+1, which is a valid expression, is not an lvalue.

If you're trying to add 1 to p, the correct syntax is:

p = p + 1;

Create an AJAX postback method which writes a CSV file to your webserver and returns the url.. Set a hidden IFrame in the browser to the location of the CSV file on the server.

Your user will then be presented with the CSV download link.

I experienced same problem where crons are not running. We fixed by changing permissions and owner by Crons made root owner as we had mentioned in crontab AND Cronjobs 644 permission given

If you're using Bash, you don't even have to use grep:

files="*.jpg"
regex="[0-9]+_([a-z]+)_[0-9a-z]*"
for f in $files    # unquoted in order to allow the glob to expand
do
    if [[ $f =~ $regex ]]
    then
        name="${BASH_REMATCH[1]}"
        echo "${name}.jpg"    # concatenate strings
        name="${name}.jpg"    # same thing stored in a variable
    else
        echo "$f doesn't match" >&2 # this could get noisy if there are a lot of non-matching files
    fi
done

It's better to put the regex in a variable. Some patterns won't work if included literally.

This uses =~ which is Bash's regex match operator. The results of the match are saved to an array called $BASH_REMATCH. The first capture group is stored in index 1, the second (if any) in index 2, etc. Index zero is the full match.

You should be aware that without anchors, this regex (and the one using grep) will match any of the following examples and more, which may not be what you're looking for:

123_abc_d4e5
xyz123_abc_d4e5
123_abc_d4e5.xyz
xyz123_abc_d4e5.xyz

To eliminate the second and fourth examples, make your regex like this:

^[0-9]+_([a-z]+)_[0-9a-z]*

which says the string must start with one or more digits. The carat represents the beginning of the string. If you add a dollar sign at the end of the regex, like this:

^[0-9]+_([a-z]+)_[0-9a-z]*$

then the third example will also be eliminated since the dot is not among the characters in the regex and the dollar sign represents the end of the string. Note that the fourth example fails this match as well.

If you have GNU grep (around 2.5 or later, I think, when the \K operator was added):

name=$(echo "$f" | grep -Po '(?i)[0-9]+_\K[a-z]+(?=_[0-9a-z]*)').jpg

The \K operator (variable-length look-behind) causes the preceding pattern to match, but doesn't include the match in the result. The fixed-length equivalent is (?<=) - the pattern would be included before the closing parenthesis. You must use \K if quantifiers may match strings of different lengths (e.g. +, *, {2,4}).

The (?=) operator matches fixed or variable-length patterns and is called "look-ahead". It also does not include the matched string in the result.

In order to make the match case-insensitive, the (?i) operator is used. It affects the patterns that follow it so its position is significant.

The regex might need to be adjusted depending on whether there are other characters in the filename. You'll note that in this case, I show an example of concatenating a string at the same time that the substring is captured.

  <form>     
            <div class="form-group">
                <label for="nameLabel">Name</label>
                <input id="name" name="name" class="form-control" type="text" /> 
            </div>
            <div class="form-group">
                <label for="PhoneLabel">Phone</label>
                <input id="phone" name="phone" class="form-control" type="text" /> 
            </div>
            <div class="form-group">
                <label for="yearLabel">Year</label>
                <input id="year" name="year" class="form-control" type="text" />
            </div>
        </form>

I think this might help.

Open web.config file and find the System.Web.Mvc assembly definition:

assembly="System.Web.Mvc, Version=3.0.0.0 ..."

It's an MVC3 as you see. Via web you can use MvcDiagnostics which is similar to phpinfo() functionality in PHP.

Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.

JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.

JComponent - A base class for objects which intend to interact with Swing.

JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).

JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.

I was struggling with this, my app was installing but not complete (almost 60% I can say) in iOS8, but in iOS7.1 it was working as expected. The error message popped was:

"Cannot install at this time". 

Finally Zillan's link helped me to get apple documentation. So, check:

1. make sure the internet reachability in your device as you will be in local network/ intranet.
2. Also make sure the address ax.init.itunes.apple.com is not getting blocked by your firewall/proxy (Just type this address in safari, a blank page must load).

As soon as I changed the proxy it installed completely. Hope it will help someone.

It seems you can just display both dfs using a comma in between in display. I noticed this on some notebooks on github. This code is from Jake VanderPlas's notebook.

class display(object):
    """Display HTML representation of multiple objects"""
    template = """<div style="float: left; padding: 10px;">
    <p style='font-family:"Courier New", Courier, monospace'>{0}</p>{1}
    </div>"""
    def __init__(self, *args):
        self.args = args

    def _repr_html_(self):
        return '\n'.join(self.template.format(a, eval(a)._repr_html_())
                     for a in self.args)

    def __repr__(self):
        return '\n\n'.join(a + '\n' + repr(eval(a))
                       for a in self.args)

display('df', "df2")

This will submit the right form response (i.e. Select value most of the time, and Input value when the Select box is set to "others"). Uses jQuery:

  $("select[name="color"]").change(function(){
    new_value = $(this).val();
    if (new_value == "others") {
      $('input[name="color"]').show();      
    } else {
      $('input[name="color"]').val(new_value);
      $('input[name="color"]').hide();
    }
  });

Try this:

public class ConnectionProvider
    {
        DbConnection conn;
        string connectionString;
        DbProviderFactory factory;

        // Constructor that retrieves the connectionString from the config file
        public ConnectionProvider()
        {
            this.connectionString = ConfigurationManager.ConnectionStrings[0].ConnectionString.ToString();
            factory = DbProviderFactories.GetFactory(ConfigurationManager.ConnectionStrings[0].ProviderName.ToString());
        }

        // Constructor that accepts the connectionString and Database ProviderName i.e SQL or Oracle
        public ConnectionProvider(string connectionString, string connectionProviderName)
        {
            this.connectionString = connectionString;
            factory = DbProviderFactories.GetFactory(connectionProviderName);
        }

        // Only inherited classes can call this.
        public DbConnection GetOpenConnection()
        {
            conn = factory.CreateConnection();
            conn.ConnectionString = this.connectionString;
            conn.Open();

            return conn;
        }

    }

I was reading this thread and would like to add information even though it is surely no longer timely for the OP.

BiggerDon above points out the difficulty of rote replacing "North" with "N". A similar problem exists with "Avenue" to "Ave" (e.g. "Avenue of the Americas" becomes "Ave of the Americas": still understandable, but probably not what the OP wants.

The replace() function is entirely context-free, but addresses are not. A complete solution needs to have additional logic to interpret the context correctly, and then apply replace() as needed.

Databases commonly contain addresses, and so I wanted to point out that the generalized version of the OP's problem as applied to addresses within the United States has been addressed (humor!) by the Coding Accuracy Support System (CASS). CASS is a database tool that accepts a U.S. address and completes or corrects it to meet a standard set by the U.S. Postal Service. The Wikipedia entry https://en.wikipedia.org/wiki/Postal_address_verification has the basics, and more information is available at the Post Office: https://ribbs.usps.gov/index.cfm?page=address_info_systems

If you want downloads number for each customer, use:

select ssn
     , sum(time)
  from downloads
 group by ssn

If you want just one record -- for a customer with highest number of downloads -- use:

select *
  from (
        select ssn
             , sum(time)
          from downloads
         group by ssn
         order by sum(time) desc
       )
 where rownum = 1

However if you want to see all customers with the same number of downloads, which share the highest position, use:

select *
  from (
        select ssn
             , sum(time)
             , dense_rank() over (order by sum(time) desc) r
          from downloads
         group by ssn
       )
 where r = 1

For future Googlers i've a different approach to check if it's last element. It's similar to last lines in OP question.

This directly compares elements rather than just checking index numbers.

$yourset.each(function() {
    var $this = $(this);
    if($this[0] === $yourset.last()[0]) {
        //$this is the last one
    }
});

In ES6 you can do as following:

 for (let i = 0; i <= 10; i++){       _x000D_
     setTimeout(function () {   _x000D_
        console.log(i);_x000D_
     }, i*3000)_x000D_
 }

In ES5 you can do as:

for (var i = 0; i <= 10; i++){_x000D_
   (function(i) {          _x000D_
     setTimeout(function () {   _x000D_
        console.log(i);_x000D_
     }, i*3000)_x000D_
   })(i);  _x000D_
 }

The reason is, let allows you to declare variables that are limited to a scope of a block statement, or expression on which it is used, unlike the var keyword, which defines a variable globally, or locally to an entire function regardless of block scope.

I know it has been a while since this was posted, but I think this will help too. I wanted to count unique values and filter the groups by number of these unique values, this is how I did it:

df.groupby('group').agg(['min','max','count','nunique']).reset_index(drop=False)

In Rails 4 all I had to do was the def change

def change
  rename_table :old_table_name, :new_table_name
end

And all of my indexes were taken care of for me. I did not need to manually update the indexes by removing the old ones and adding new ones.

And it works using the change for going up or down in regards to the indexes as well.

You can use the user-agent string to detect this.

var useragent = navigator.userAgent.toLowerCase();

if( useragent.search("iphone") )
    ; // iphone
else if( useragent.search("ipod") )
    ; // ipod
else if( useragent.search("android") )
    ; // android
etc

You can find a list of useragent strings here http://www.useragentstring.com/pages/useragentstring.php

This is what worked for me

$scope.form_name.field_name.$setDirty()

You could use a CURSOR in this case:

DECLARE @id INT
DECLARE @name NVARCHAR(100)
DECLARE @getid CURSOR

SET @getid = CURSOR FOR
SELECT table.id,
       table.name
FROM   table

OPEN @getid
FETCH NEXT
FROM @getid INTO @id, @name
WHILE @@FETCH_STATUS = 0
BEGIN
    EXEC stored_proc @varName=@id, @otherVarName='test', @varForName=@name
    FETCH NEXT
    FROM @getid INTO @id, @name
END

CLOSE @getid
DEALLOCATE @getid

Modified to show multiple parameters from the table.

That's a half-open interval.

• A closed interval [a,b] includes the end points.
• An open interval (a,b) excludes them.

In your case the end-point at the start of the interval is included, but the end is excluded. So it means the interval "first1 <= x < last1".

Half-open intervals are useful in programming because they correspond to the common idiom for looping:

for (int i = 0; i < n; ++i) { ... } 

Here i is in the range [0, n).

You can just use the error function that's built in to the math library, as stated on their website.

An "if" is not a loop. Just use the break inside the "if" and it will break out of the "while".

If you ever need to use genuine nested loops, Java has the concept of a labeled break. You can put a label before a loop, and then use the name of the label is the argument to break. It will break outside of the labeled loop.

In general you can easily write the Where-Condition like this:

select * from tab1
where (col1, col2) in (select col1, col2 from tab2)

Note
Oracle ignores rows where one or more of the selected columns is NULL. In these cases you probably want to make use of the NVL-Funktion to map NULL to a special value (that should not be in the values):

select * from tab1
where (col1, NVL(col2, '---') in (select col1, NVL(col2, '---') from tab2)

import re
regex = ur"\[P\] (.+?) \[/P\]+?"
line = "President [P] Barack Obama [/P] met Microsoft founder [P] Bill Gates [/P], yesterday."
person = re.findall(regex, line)
print(person)

yields

['Barack Obama', 'Bill Gates']

The regex ur"[\u005B1P\u005D.+?\u005B\u002FP\u005D]+?" is exactly the same unicode as u'[[1P].+?[/P]]+?' except harder to read.

The first bracketed group [[1P] tells re that any of the characters in the list ['[', '1', 'P'] should match, and similarly with the second bracketed group [/P]].That's not what you want at all. So,

• Remove the outer enclosing square brackets. (Also remove the stray 1 in front of P.)
• To protect the literal brackets in [P], escape the brackets with a backslash: \[P\].
• To return only the words inside the tags, place grouping parentheses around .+?.

Just in case you have a nullable property in your class object:

private static DataTable ConvertToDatatable<T>(List<T> data)
{
    PropertyDescriptorCollection props = TypeDescriptor.GetProperties(typeof(T));
    DataTable table = new DataTable();
    for (int i = 0; i < props.Count; i++)
    {
        PropertyDescriptor prop = props[i];
        if (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>))
            table.Columns.Add(prop.Name, prop.PropertyType.GetGenericArguments()[0]); 
        else
            table.Columns.Add(prop.Name, prop.PropertyType);
    }

    object[] values = new object[props.Count];
    foreach (T item in data)
    {
        for (int i = 0; i < values.Length; i++)
        {
            values[i] = props[i].GetValue(item);
        }
        table.Rows.Add(values);
    }
    return table;
 }

int[] arr = Enumerable.Repeat(42, 10000).ToArray();

I believe that this does the job :)

I know this have been answered by others, but i found the another article that covered also for no background event - tableview or scrollview.

http://samwize.com/2014/03/27/dismiss-keyboard-when-tap-outside-a-uitextfield-slash-uitextview/

I had what at first seemed to be an identical problem, but it turned out to be due to an NHibernate/WPF compatibility issue. The problem was caused by the way WPF checks for object equality. I was able to get my stuff to work by using the object ID property in the SelectedValue and SelectedValuePath properties.

<ComboBox Name="CategoryList"
          DisplayMemberPath="CategoryName"
          SelectedItem="{Binding Path=CategoryParent}"
          SelectedValue="{Binding Path=CategoryParent.ID}"
          SelectedValuePath="ID">

See the blog post from Chester, The WPF ComboBox - SelectedItem, SelectedValue, and SelectedValuePath with NHibernate, for details.

I have recently written a plugin that does exactly that - jquery.initialize

You use it the same way as .each function

$(".some-element").initialize( function(){
    $(this).css("color", "blue"); 
});

The difference from .each is - it takes your selector, in this case .some-element and wait for new elements with this selector in the future, if such element will be added, it will be initialized too.

In our case initialize function just change element color to blue. So if we'll add new element (no matter if with ajax or even F12 inspector or anything) like:

$("<div/>").addClass('some-element').appendTo("body"); //new element will have blue color!

Plugin will init it instantly. Also plugin makes sure one element is initialized only once. So if you add element, then .detach() it from body and then add it again, it will not be initialized again.

$("<div/>").addClass('some-element').appendTo("body").detach()
    .appendTo(".some-container");
//initialized only once

Plugin is based on MutationObserver - it will work on IE9 and 10 with dependencies as detailed on the readme page.

The solution for the error is to add this line at the top of the code:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

If you need to mutate stuff, use ArrayBuffer or LinkedBuffer instead. However, it would be better to address this statement:

I need to declare empty list or empty maps and some where later in the code need to fill them.

Instead of doing that, fill the list with code that returns the elements. There are many ways of doing that, and I'll give some examples:

// Fill a list with the results of calls to a method
val l = List.fill(50)(scala.util.Random.nextInt)

// Fill a list with the results of calls to a method until you get something different
val l = Stream.continually(scala.util.Random.nextInt).takeWhile(x => x > 0).toList

// Fill a list based on its index
val l = List.tabulate(5)(x => x * 2)

// Fill a list of 10 elements based on computations made on the previous element
val l = List.iterate(1, 10)(x => x * 2)

// Fill a list based on computations made on previous element, until you get something
val l = Stream.iterate(0)(x => x * 2 + 1).takeWhile(x => x < 1000).toList

// Fill list based on input from a file
val l = (for (line <- scala.io.Source.fromFile("filename.txt").getLines) yield line.length).toList

To calculate MD5 hash of CLOB content field with my desired encoding without implicitly recoding content to AL32UTF8, I've used this code:

create or replace function clob2blob(AClob CLOB) return BLOB is
  Result BLOB;
  o1 integer;
  o2 integer;
  c integer;
  w integer;
begin
  o1 := 1;
  o2 := 1;
  c := 0;
  w := 0;
  DBMS_LOB.CreateTemporary(Result, true);
  DBMS_LOB.ConvertToBlob(Result, AClob, length(AClob), o1, o2, 0, c, w);
  return(Result);
end clob2blob;
/

update my_table t set t.hash = (rawtohex(DBMS_CRYPTO.Hash(clob2blob(t.content),2)));

For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:

<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

While this will not (note the leading space before the opening <? tag)

 <?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

Also, this will not work either (the echo will break it):

<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.

add ob_start (); at the top and at the end add ob_end_flush();

<?php
    ob_start();
    require('fpdf.php');
    $pdf = new FPDF();
    $pdf->AddPage();
    $pdf->SetFont('Arial','B',16);
    $pdf->Cell(40,10,'Hello World!');
    $pdf->Output();
    ob_end_flush(); 
?>

give me an error as below:
FPDF error: Some data has already been output, can't send PDF

to over come this error: go to fpdf.php in that,goto line number 996

function Output($name='', $dest='')

after that make changes like this:

function Output($name='', $dest='') {   
    ob_clean();     //Output PDF to so

Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.

<?

while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);

?>

cheers :-)

In my case i had set:

ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);

When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off the display_errors option, the report was generated successfully.

for single condition, ie. ( 'employrate'] > 70 )

       country        employrate alcconsumption

4       Angola  75.6999969482422           5.57

use this:

df.loc[df['employrate'] > 70, 'employrate'] = 7

       country  employrate alcconsumption

4       Angola    7.000000           5.57

therefore syntax here is:

df.loc[<mask>(here mask is generating the labels to index) , <optional column(s)> ]

For multiple conditions ie. (df['employrate'] <=55) & (df['employrate'] > 50)

use this:

df['employrate'] = np.where(
   (df['employrate'] <=55) & (df['employrate'] > 50) , 11, df['employrate']
   )

There are basically 2 things to bear in mind. You are only allowed to set it to NO if you either don't use encryption at all, or you are part of the exempt regulations. This applies to the following kind of applications:

Note: These regulations are also true for testing your app using TestFlight

My favorite programming language is JavaScript

function mergeSortedArrays(a, b){
    var result = [];

    var sI = 0;
    var lI = 0;
    var smallArr;
    var largeArr;
    var temp;

    if(typeof b[0] === 'undefined' || a[0]<b[0]){
        smallArr = a;
        largeArr = b;
    } else{
        smallArr = b;
        largeArr = a;
    }

    while(typeof smallArr[sI] !== 'undefined'){
        result.push(smallArr[sI]);
        sI++;

        if(smallArr[sI]>largeArr[lI] || typeof smallArr[sI] === 'undefined'){
            temp = smallArr;
            smallArr = largeArr;
            largeArr = temp;
            temp = sI;
            sI = lI;
            lI = temp;
        }
    }
    return result;
}

Use anonymous class

Shape your model the way you want using anonymous classes:

var root = new 
{ 
    car = new 
    { 
        name = "Ford", 
        owner = "Henry"
    }
};

string json = JsonConvert.SerializeObject(root);

For ExpressJs router:

router.post('/login', async(req, res) => {
    return res.send({redirect: '/yoururl'});
})

Client-side:

    success: function (response) {
        if (response.redirect) {
            window.location = response.redirect
        }
    },

JavaScript code runs on a single thread, so you cannot principally block to wait for the first loop iteration to complete before beginning the next without seriously impacting page usability.

The solution depends on what you really need. If the example is close to exactly what you need, @Simon's suggestion to pass i to your async process is a good one.

After looking at Alex's and Gerty3000's answer, I have tried to shorten the one-liner:

Basically, using git log numstat and not keeping track of the number of files changed.

Git version 2.1.0 on Mac OSX:

git log --format='%aN' | sort -u | while read name; do echo -en "$name\t"; git log --author="$name" --pretty=tformat: --numstat | awk '{ add += $1; subs += $2; loc += $1 - $2 } END { printf "added lines: %s, removed lines: %s, total lines: %s\n", add, subs, loc }' -; done

Example:

Jared Burrows   added lines: 6826, removed lines: 2825, total lines: 4001

As the documentation states ^[docs],

In user defined base classes, abstract methods should raise this exception when they require derived classes to override the method, or while the class is being developed to indicate that the real implementation still needs to be added.

Note that although the main stated use case this error is the indication of abstract methods that should be implemented on inherited classes, you can use it anyhow you'd like, like for indication of a TODO marker.

Use a summary (-s) and bytes (-b). You can cut the first field of the summary with cut. Putting it all together:

CHECK=$(du -sb /data/sflow_log | cut -f1)

^[ _]*[A-Z0-9][A-Z0-9 _]*$

You can optionally have some spaces or underscores up front, then you need one letter or number, and then an arbitrary number of numbers, letters, spaces or underscores after that.

Something that contains only spaces and underscores will fail the [A-Z0-9] portion.

According to this Video if you use the ProGuard you don't need even think about Enums performance issues!!

Proguard can in many situations optimize Enums to INT values on your behalf so really don't need to think about it or do any work.

you can use np.int_:

>>> x = np.array([[1.0, 2.3], [1.3, 2.9]])
>>> x
array([[ 1. ,  2.3],
       [ 1.3,  2.9]])
>>> np.int_(x)
array([[1, 2],
       [1, 2]])

I had the same problem with a webapp getting data from ASP.NET webservice

This worked for me:

public WebService()
{
    HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
    ...
}

Proper pure bash way

Under bash, you could simply:

IFS=\| read -ra headline <stores.dat
echo ${#headline[@]}
4

A lot quicker as without forks, and reusable as $headline hold the full head line. You could, for sample:

printf " - %s\n" "${headline[@]}"
 - sid
 - storeNo
 - latitude
 - longitude

Nota This syntax will drive correctly spaces and others characters in column names.

Alternative: strong binary checking for max columns on each rows

What if some row do contain some extra columns?

This command will search for bigger line, counting separators:

tr -dc $'\n|' <stores.dat |wc -L
3

There are max 3 separators, then 4 fields.

All you need to do is using

getFragmentManager()

method on your fragment. It will give you the support fragment manager, when you used it while adding this fragment.

If you use <mvc:annotation-driven/> it should be after beans.

You do not need to user where clause while ordering the data alphabetically. here is my code

SELECT * FROM tbl_name ORDER BY field_name

that's it. It return the data in alphabetical order ie; From A to Z. :)

You can simply cast to List and then check if every element can be casted to T.

public <T> List<T> asList(final Class<T> clazz) {
    List<T> values = (List<T>) this.value;
    values.forEach(clazz::cast);
    return values;
}

XmlDocument d = new XmlDocument();
d.Load(@"D:\Work_Time_Calculator\10-07-2013.xml");
XmlNodeList n = d.GetElementsByTagName("Short_Fall");
if(n != null) {
    Console.WriteLine(n[0].InnerText); //Will output '08:29:57'
}

or you could wrap in foreach loop to print each value

XmlDocument d = new XmlDocument();
d.Load(@"D:\Work_Time_Calculator\10-07-2013.xml");
XmlNodeList n = d.GetElementsByTagName("Short_Fall");
if(n != null) {
    foreach(XmlNode curr in n) {
        Console.WriteLine(curr.InnerText);
    }
}

Another way is to do :

md5sum filename |cut -f 1 -d " "

Cut will split line to each space and return only first field.

This code splits lines from text, and add everyone into a vector.

vector<string> split(char *phrase, string delimiter){
    vector<string> list;
    string s = string(phrase);
    size_t pos = 0;
    string token;
    while ((pos = s.find(delimiter)) != string::npos) {
        token = s.substr(0, pos);
        list.push_back(token);
        s.erase(0, pos + delimiter.length());
    }
    list.push_back(s);
    return list;
}

Called by:

vector<string> listFilesMax = split(buffer, "\n");

Personally, I use Charles for that kind of stuff.
When enabled, it will monitor every network request, displaying extended request details, including support for SSL and various request/reponse format, like JSON, etc...

You can also configure it to sniff only requests to specific servers, not the whole traffic.

It's commercial software, but there is a trial, and IMHO it's definitively a great tool.

Well, you are using both frame.setSize() and frame.pack().

You should use one of them at one time.

Using setSize() you can give the size of frame you want but if you use pack(), it will automatically change the size of the frames according to the size of components in it. It will not consider the size you have mentioned earlier.

Try removing frame.pack() from your code or putting it before setting size and then run it.

You can use the -f operator

$a = "{0:D}" -f (get-date)
$a = "{0:dddd}" -f (get-date)

Late answer, I know, but for me the following script is quite useful - and it answers the question too, hitting two flys with one flag ;-)

The following script expands SendTo in the file explorer's context menu:

@echo off
cls
if "%~dp1"=="" goto Install

REM change drive, then cd to path given and run shell there
%~d1
cd "%~dp1"
cmd /k
goto End

:Install
rem No arguments: Copies itself into SendTo folder
copy "%0" "%appdata%\Microsoft\Windows\SendTo\A - Open in CMD shell.cmd"

:End

If you run this script without any parameters by double-clicking on it, it will copy itself to the SendTo folder and renaming it to "A - Open in CMD shell.cmd". Afterwards it is available in the "SentTo" context menu.

Then, right-click on any file or folder in Windows explorer and select "SendTo > A - Open in CMD shell.cmd"

The script will change drive and path to the path containing the file or folder you have selected and open a command shell with that path - useful for Visual Studio Code, because then you can just type "code ." to run it in the context of your project.

How does it work?

%0 - full path of the batch script
%~d1 - the drive contained in the first argument (e.g. "C:")
%~dp1 - the path contained in the first argument
cmd /k - opens a command shell which stays open

Not used here, but %~n1 is the file name of the first argument.

I hope this is helpful for someone.

In my particular project I couldn't get it to work, and used declare var $;. Not a clean/recommended solution, it doesnt recognise the JQuery variables, but I had no errors after using that (and had to for my automatic builds to succeed).

From the offical docs: (http://api.jquery.com/hover/)

The .hover() method binds handlers for both mouseenter and mouseleave events. You can use it to simply apply behavior to an element during the time the mouse is within the element.

Just do a random click on any non input item. Keyboard will disappear.

git Stash list 

List will show all stashed items eg:stash@{0}:,stash@{1}:,..,stash@{n}:

Then select the number n which denotes stash@{n}:

git stash apply n 

for example:

git stash apply 1 

will apply that particular stashed changes to the current branch

@Iggy answer sets JSON serialization of c# enum as string only for ASP.NET (Web API and so).

But to make it work also with ad hoc serialization, add following to your start class (like Global.asax Application_Start)

//convert Enums to Strings (instead of Integer) globally
JsonConvert.DefaultSettings = (() =>
{
    var settings = new JsonSerializerSettings();
    settings.Converters.Add(new StringEnumConverter { CamelCaseText = true });
    return settings;
});

More information on the Json.NET page

Additionally, to have your enum member to serialize/deserialize to/from specific text, use the

System.Runtime.Serialization.EnumMember

attribute, like this:

public enum time_zone_enum
{
    [EnumMember(Value = "Europe/London")] 
    EuropeLondon,

    [EnumMember(Value = "US/Alaska")] 
    USAlaska
}

Try setting a custom CultureInfo for CurrentCulture and CurrentUICulture:

Globalization.CultureInfo customCulture = new Globalization.CultureInfo("en-US", true);

customCulture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd h:mm tt";

System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
System.Threading.Thread.CurrentThread.CurrentUICulture = customCulture;

DateTime newDate = System.Convert.ToDateTime(DateTime.Now.ToString("yyyy-MM-dd h:mm tt"));

You can use inbuilt library pickle

This library allows you to save any object in python to a file

This library will maintain the format as well

import pickle
with open('/content/list_1.txt', 'wb') as fp:
    pickle.dump(list_1, fp)

you can also read the list back as an object using same library

with open ('/content/list_1.txt', 'rb') as fp:
    list_1 = pickle.load(fp)

My table has 100 fields, and I needed a query to just work. Now I can switch out any number of fields with some basic conditional logic and not worry about its ordinal position.

1. Replace the below table name with your table name

   SQLcolums = "SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE (TABLE_NAME = 'TABLE-NAME')"
   
   Set GetColumns = Conn.Execute(SQLcolums)
   Do WHILE not GetColumns.eof
   
   colName = GetColumns("COLUMN_NAME")
   

2. Replace the original identity field name with your PK field name

   IF colName = "ORIGINAL-IDENTITY-FIELD-NAME" THEN ' ASSUMING THAT YOUR PRIMARY KEY IS THE FIRST FIELD DONT WORRY ABOUT COMMAS AND SPACES
       columnListSOURCE = colName 
       columnListTARGET = "[PreviousId field name]"
   ELSE
       columnListSOURCE = columnListSOURCE & colName
       columnListTARGET = columnListTARGET & colName
   END IF
   
   GetColumns.movenext
   
   loop
   
   GetColumns.close    
   

3. Replace the table names again (both target table name and source table name); edit your where conditions

   SQL = "INSERT INTO TARGET-TABLE-NAME (" & columnListTARGET & ") SELECT " & columnListSOURCE & " FROM SOURCE-TABLE-NAME WHERE (FIELDNAME = FIELDVALUE)" 
   Conn.Execute(SQL)
   

Having issues building with ANT? Keep reading

If ant -f core/build.xml says something like:

Unable to locate tools.jar. Expected to find it in
C:\Program Files\Java\jre6\lib\tools.jar

then set your JAVA_HOME environment variable to the proper java folder. I found tools.jar in my (for Windows):

C:\Program Files\Java\jdk1.6.0_21\lib

so I set my JAVA_HOME to:

C:\Progra~1\Java\jdk1.6.0_25

the reason for the shorter syntax I found at some site which says:

"It is strongly advised that you choose an installation directory that does not include spaces in the path name (e.g., do NOT install in C:\Program Files). If Java is installed in such a directory, it is critical to set the JAVA_HOME environment variable to a path that does not include spaces (e.g., C:\Progra~1); failure to do this will result in exceptions thrown by some programs that depend on the value of JAVA_HOME."

I then relaunched cmd (important because DOS shell only reads env vars upon launching, so changing an env var will require you to use a new shell to get the updated value)

and finally the ant -f core/build.xml worked.

The answer has been copied from this tutorial I wrote at LearnOpenCV.com explaining various parameters of SimpleBlobDetector. You can find additional details about the parameters in the tutorial.

Because C will promote floats to doubles for functions that take variable arguments. Pointers aren't promoted to anything, so you should be using %lf, %lg or %le (or %la in C99) to read in doubles.

They are absolutely different. Inheritance is an "is-a" relationship. Composition is a "has-a".

You do composition by having an instance of another class C as a field of your class, instead of extending C. A good example where composition would've been a lot better than inheritance is java.util.Stack, which currently extends java.util.Vector. This is now considered a blunder. A stack "is-NOT-a" vector; you should not be allowed to insert and remove elements arbitrarily. It should've been composition instead.

Unfortunately it's too late to rectify this design mistake, since changing the inheritance hierarchy now would break compatibility with existing code. Had Stack used composition instead of inheritance, it can always be modified to use another data structure without violating the API.

I highly recommend Josh Bloch's book Effective Java 2nd Edition

• Item 16: Favor composition over inheritance
• Item 17: Design and document for inheritance or else prohibit it

Good object-oriented design is not about liberally extending existing classes. Your first instinct should be to compose instead.

Actually it's not an error! It means you should enter some message to mark this merge. My OS is Ubuntu 14.04.If you use the same OS, you just need to do this as follows:

1. Type some message

2. CtrlCO

3. Type the file name (such as "Merge_feature01") and press Enter

4. CtrlX to exit

Now if you go to .git and you will find the file "Merge_feature01", that's the merge log actually.

This thread is a bit older, but thought I'd post what I currently do (work in progress).

Though I'm still hitting situations where the system is under heavy load and when I click a submit button (e.g., login.jsp), all three conditions (see below) return true but the next page (e.g., home.jsp) hasn't started loading yet.

This is a generic wait method that takes a list of ExpectedConditions.

public boolean waitForPageLoad(int waitTimeInSec, ExpectedCondition<Boolean>... conditions) {
    boolean isLoaded = false;
    Wait<WebDriver> wait = new FluentWait<>(driver)
            .withTimeout(waitTimeInSec, TimeUnit.SECONDS)
            .ignoring(StaleElementReferenceException.class)
            .pollingEvery(2, TimeUnit.SECONDS);
    for (ExpectedCondition<Boolean> condition : conditions) {
        isLoaded = wait.until(condition);
        if (isLoaded == false) {
            //Stop checking on first condition returning false.
            break;
        }
    }
    return isLoaded;
}

I have defined various reusable ExpectedConditions (three are below). In this example, the three expected conditions include document.readyState = 'complete', no "wait_dialog" present, and no 'spinners' (elements indicating async data is being requested).

Only the first one can be generically applied to all web pages.

/**
 * Returns 'true' if the value of the 'window.document.readyState' via
 * JavaScript is 'complete'
 */
public static final ExpectedCondition<Boolean> EXPECT_DOC_READY_STATE = new ExpectedCondition<Boolean>() {
    @Override
    public Boolean apply(WebDriver driver) {
        String script = "if (typeof window != 'undefined' && window.document) { return window.document.readyState; } else { return 'notready'; }";
        Boolean result;
        try {
            result = ((JavascriptExecutor) driver).executeScript(script).equals("complete");
        } catch (Exception ex) {
            result = Boolean.FALSE;
        }
        return result;
    }
};
/**
 * Returns 'true' if there is no 'wait_dialog' element present on the page.
 */
public static final ExpectedCondition<Boolean> EXPECT_NOT_WAITING = new ExpectedCondition<Boolean>() {
    @Override
    public Boolean apply(WebDriver driver) {
        Boolean loaded = true;
        try {
            WebElement wait = driver.findElement(By.id("F"));
            if (wait.isDisplayed()) {
                loaded = false;
            }
        } catch (StaleElementReferenceException serex) {
            loaded = false;
        } catch (NoSuchElementException nseex) {
            loaded = true;
        } catch (Exception ex) {
            loaded = false;
            System.out.println("EXPECTED_NOT_WAITING: UNEXPECTED EXCEPTION: " + ex.getMessage());
        }
        return loaded;
    }
};
/**
 * Returns true if there are no elements with the 'spinner' class name.
 */
public static final ExpectedCondition<Boolean> EXPECT_NO_SPINNERS = new ExpectedCondition<Boolean>() {
    @Override
    public Boolean apply(WebDriver driver) {
        Boolean loaded = true;
        try {
        List<WebElement> spinners = driver.findElements(By.className("spinner"));
        for (WebElement spinner : spinners) {
            if (spinner.isDisplayed()) {
                loaded = false;
                break;
            }
        }
        }catch (Exception ex) {
            loaded = false;
        }
        return loaded;
    }
};

Depending on the page, I may use one or all of them:

waitForPageLoad(timeoutInSec,
            EXPECT_DOC_READY_STATE,
            EXPECT_NOT_WAITING,
            EXPECT_NO_SPINNERS
    );

There are also predefined ExpectedConditions in the following class: org.openqa.selenium.support.ui.ExpectedConditions

It is very complex to invoke Win32 from C#.

You should use the tool Handle.exe.

After that your C# code have to be the following:

string fileName = @"c:\aaa.doc";//Path to locked file

Process tool = new Process();
tool.StartInfo.FileName = "handle.exe";
tool.StartInfo.Arguments = fileName+" /accepteula";
tool.StartInfo.UseShellExecute = false;
tool.StartInfo.RedirectStandardOutput = true;
tool.Start();           
tool.WaitForExit();
string outputTool = tool.StandardOutput.ReadToEnd();

string matchPattern = @"(?<=\s+pid:\s+)\b(\d+)\b(?=\s+)";
foreach(Match match in Regex.Matches(outputTool, matchPattern))
{
    Process.GetProcessById(int.Parse(match.Value)).Kill();
}

When you import lib, you're importing the package. The only file to get evaluated and run in this case is the 0 byte __init__.py in the lib directory.

If you want access to your function, you can do something like this from lib.mod1 import mod1 and then run the mod12 function like so mod1.mod12().

If you want to be able to access mod1 when you import lib, you need to put an import mod1 inside the __init__.py file inside the lib directory.

A couple of things wrong here.

1. Do you really want to open and close the connection for every single log entry?

2. Shouldn't you be using SqlCommand instead of SqlDataAdapter?

3. The data adapter (or SqlCommand) needs exactly what the error message tells you it's missing: an active connection. Just because you created a connection object does not magically tell C# that it is the one you want to use (especially if you haven't opened the connection).

I highly recommend a C# / SQL Server tutorial.

If you picture box in the background then use this:

label1.Parent = pictureBox1;
label1.BackColor = Color.Transparent;

Put this code below InitializeComponent(); or in Form_Load Method.

Ref: https://www.c-sharpcorner.com/blogs/how-to-make-a-transparent-label-over-a-picturebox1

For some reason other answers are unnecessarily complex, it's easy to do it in one line in pure JavaScript:

Array.prototype.find.call(selectElement.options, o => o.value === optionValue).disabled = true;

or

selectElement.querySelector('option[value="'+optionValue.replace(/["\\]/g, '\\$&')+'"]').disabled = true;

The performance depends on the number of the options (the more the options, the slower the first one) and whether you can omit the escaping (the replace call) from the second one. Also the first one uses Array.find and arrow functions that are not available in IE11.

var datatoday = new Date();
var datatodays = datatoday.setDate(new Date(datatoday).getDate() + 1);
todate = new Date(datatodays);
console.log(todate);

This will help you...

You could just do a simple extension like:

import UIKit

// MARK: - Mixed string utils and helpers
extension String {


    /**
    Encode a String to Base64

    :returns: 
    */
    func toBase64()->String{

        let data = self.dataUsingEncoding(NSUTF8StringEncoding)

        return data!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))

    }

}

iOS 7 and up

Take a look at the help page for merge. The all parameter lets you specify different types of merges. Here we want to set all = TRUE. This will make merge return NA for the values that don't match, which we can update to 0 with is.na():

zz <- merge(df1, df2, all = TRUE)
zz[is.na(zz)] <- 0

> zz
  x y
1 a 0
2 b 1
3 c 0
4 d 0
5 e 0

Updated many years later to address follow up question

You need to identify the variable names in the second data table that you aren't merging on - I use setdiff() for this. Check out the following:

df1 = data.frame(x=c('a', 'b', 'c', 'd', 'e', NA))
df2 = data.frame(x=c('a', 'b', 'c'),y1 = c(0,1,0), y2 = c(0,1,0))

#merge as before
df3 <- merge(df1, df2, all = TRUE)
#columns in df2 not in df1
unique_df2_names <- setdiff(names(df2), names(df1))
df3[unique_df2_names][is.na(df3[, unique_df2_names])] <- 0

Since all the players are numbered I would just use an ArrayList<Player>()

Something like

List<Player> players = new ArrayList<Player>();

System.out.printf("Give the number of the players ");
int number_of_players = scanner.nextInt();
scanner.nextLine(); // discard the rest of the line.

for(int k = 0;k < number_of_players; k++){
     System.out.printf("Give the name of player %d: ", k + 1);
     String name_of_player = scanner.nextLine();
     players.add(new Player(name_of_player,0)); //k=id and 0=score
}

for(Player player: players) {  
    System.out.println("Name of player in this round:" + player.getName());

This is not possible due to the Same Origin Policy.

You will need to switch the Ajax requests to https, too.

I was very frustrated trying to achieve a fitty-like tight text wrapping so I ended up using a canvas-based method which I arrived at by unsuccessfully trying other methods. What I was aiming for looks like the attached which turns out to be surprisingly difficult (for me). Hopefully one day we will have a simple CSS-only way of doing this. Downsides of this approach is the text is treated more like an image, but for some use cases this is fine.

At its core, Git is a set of command line utility programs that are designed to execute on a Unix style command-line environment. Modern operating systems like Linux and macOS both include built-in Unix command line terminals. This makes Linux and macOS complementary operating systems when working with Git. Microsoft Windows instead uses Windows command prompt, a non-Unix terminal environment.

What is Git Bash?

Git Bash is an application for Microsoft Windows environments which provides an emulation layer for a Git command line experience. Bash is an acronym for Bourne Again Shell. A shell is a terminal application used to interface with an operating system through written commands. Bash is a popular default shell on Linux and macOS. Git Bash is a package that installs Bash, some common bash utilities, and Git on a Windows operating system.

iOS 5 has implemented Custom Vibrations mode. So in some cases variable vibration is acceptable. The only thing is unknown what library deals with that (pretty sure not CoreTelephony) and if it is open for developers. So keep on searching.

You can also Use HttpParams, such as:

  getParamValueQueryString( paramName ) {
    const url = window.location.href;
    let paramValue;
    if (url.includes('?')) {
      const httpParams = new HttpParams({ fromString: url.split('?')[1] });
      paramValue = httpParams.get(paramName);
    }
    return paramValue;
  }

Try creating a .htaccess file with the following

DirectoryIndex index.php

Edit: Actually, isn't there a 'php-apache' package or something that you're supposed to install with both of them?

For Ansible 2.x:

- name: template test
  template: 
    src: myTemplateFile
    dest: result1
  vars:
    myTemplateVariable: File1

- name: template test
  template: 
    src: myTemplateFile
    dest: result2
  vars:
    myTemplateVariable: File2

For Ansible 1.x:

Unfortunately the template module does not support passing variables to it, which can be used inside the template. There was a feature request but it was rejected.

I can think of two workarounds:

1. Include

The include statement supports passing variables. So you could have your template task inside an extra file and include it twice with appropriate parameters:

my_include.yml:

- name: template test
  template: 
        src=myTemplateFile
        dest=destination

main.yml:

- include: my_include.yml destination=result1 myTemplateVariable=File1

- include: my_include.yml destination=result2 myTemplateVariable=File2

2. Re-define myTemplateVariable

Another way would be to simply re-define myTemplateVariable right before every template task.

- set_fact:
     myTemplateVariable: File1

- name: template test 1
  template: 
        src=myTemplateFile
        dest=result1

- set_fact:
     myTemplateVariable: File2

- name: template test 2
  template: 
        src=myTemplateFile
        dest=result2

DataSet is collection of DataTables.... you can get the datatable from DataSet as below.

//here ds is dataset
DatTable dt = ds.Table[0]; /// table of dataset

I do not like referring to the number, the sybolic name is much more expressive and avoid having to add a comment that could become obsolete over time.

So I'd rather do:

#pylint: disable-msg=too-many-arguments

And I would also recommend to not leave it dangling there: it will stay active until the file ends or it is disabled, whichever comes first.

So better doing:

#pylint: disable-msg=too-many-arguments
code_which_would_trigger_the_msg
#pylint: enable-msg=too-many-arguments    

I would also recommend enabling/disabling one single warning/error per line.

$matches = array();
preg_match('/id=([0-9]+)\?/', $url, $matches);

This is safe for if the format changes. slandau's answer won't work if you ever have any other numbers in the URL.

php.net/preg-match

  get '*unmatched_route', to: 'main#not_found'

    render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false
  end

During development / testing of new releases, the cache can be a problem because the browser, the server and even sometimes the 3G telco (if you do mobile deployment) will cache the static content (e.g. JS, CSS, HTML, img). You can overcome this by appending version number, random number or timestamp to the URL e.g: JSP: <script src="js/excel.js?time=<%=new java.util.Date()%>"></script>

In case you're running pure HTML (instead of server pages JSP, ASP, PHP) the server won't help you. In browser, links are loaded before the JS runs, therefore you have to remove the links and load them with JS.

// front end cache bust
var cacheBust = ['js/StrUtil.js', 'js/protos.common.js', 'js/conf.js', 'bootstrap_ECP/js/init.js'];   
for (i=0; i < cacheBust.length; i++){
     var el = document.createElement('script');
     el.src = cacheBust[i]+"?v=" + Math.random();
     document.getElementsByTagName('head')[0].appendChild(el);
}

From https://developer.apple.com/library/prerelease/ios/documentation/swift/conceptual/swift_programming_language/CollectionTypes.html:

If you need to use a dictionary’s keys or values with an API that takes an Array instance, initialize a new array with the keys or values property:

let airportCodes = [String](airports.keys) // airportCodes is ["TYO", "LHR"]   
let airportNames = [String](airports.values) // airportNames is ["Tokyo", "London Heathrow"]

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

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

Below code may be help you just example.

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

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

Below is code to put your Linearlayout at bottom and put its content at center. You have to use RelativeLayout to set Layout at bottom.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="#97611F"
    android:gravity="center_horizontal"
    android:layout_alignParentBottom="true"
    android:orientation="horizontal">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="50dp"
        android:text="View Saved Searches"
        android:textSize="15dp"
        android:textColor="#fff"
        android:gravity="center_vertical"
        android:visibility="visible" />
    <TextView
        android:layout_width="30dp"
        android:layout_height="24dp"
        android:text="12"
        android:textSize="12dp"
        android:textColor="#fff"
        android:gravity="center_horizontal"
        android:padding="1dp"
        android:visibility="visible" />
  </LinearLayout>  
</RelativeLayout>

Per @Beau's answer, Chrome does not support localhost CORS requests, and there is unlikely any change in this direction.

I use the Allow-Control-Allow-Origin: * Chrome Extension to go around this issue. The extension will add the necessary HTTP Headers for CORS:

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: "GET, PUT, POST, DELETE, HEAD, OPTIONS"
Access-Control-Expose-Headers: <you can add values here>

The source code is published on Github.

Note that the extension filter all URLs by default. This may break some websites (for example: Dropbox). I have changed it to filter only localhost URLs with the following URL filter

*://localhost:*/*

Other solutions for Git Bash provided by others didn't work for me. Apparently there is currently a bug/limitation in Git for Windows. See this and this.

I finally managed to get it working after finding this GitHub thread (which provides some additional solutions if you're interested, which might work for you, but didn't for me).

I ended up using the following syntax:

MSYS_NO_PATHCONV=1 docker run --rm -it -v $(pwd):/usr/src/project gcc:4.9

Note the MSYS_NO_PATHCONV=1 in front of the docker command and $(pwd) - round brackets, lower-case pwd, no quotes, no backslashes.

Also, I'm using Linux containers on Windows if that matters..

I tested this in the new Windows Terminal, ConEmu and GitBash, and all of them worked for me.

I use it in form of a meta box. Here is a function that dumps values of all the meta data for post.

    function dump_all_meta(){

        echo "<h3>All Post Meta</h3>";

        // Get all the data.
        $getPostCustom=get_post_custom();


        foreach( $getPostCustom as $name=>$value ) {

            echo "<strong>".$name."</strong>"."  =>  ";

            foreach($getPostCustom as $name=>$value) {

        echo "<strong>".$name."</strong>"."  =>  ";

        foreach($value as $nameAr=>$valueAr) {
                echo "<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
                echo $nameAr."  =>  ";
                echo var_dump($valueAr);
        }

        echo "<br /><br />";

        }
    } // Callback funtion ended.

Hope it helps. You can use it inside a meta box or at the front-end.

You can use nonHistorySelectors option from jquery mobile where you do not want to track history. You can find the detailed documentation here http://jquerymobile.com/demos/1.0a4.1/#docs/api/globalconfig.html

For me, something like Abdelhak Mouaamou's answer works, tested on API level 16 and 27.

Instead of using popupWindow.getContentView().getParent() and casting the result to View (which crashes on API level 16 cause there it returns a ViewRootImpl object which isn't an instance of View) I just use .getRootView() which returns a view already, so no casting required there.

Hope it helps someone :)

complete working example scrambled together from other stackoverflow posts, just copy-paste it, e.g., in the onClick listener of a button:

// inflate the layout of the popup window
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
if(inflater == null) {
    return;
}
//View popupView = inflater.inflate(R.layout.my_popup_layout, null); // this version gives a warning cause it doesn't like null as argument for the viewRoot, c.f. https://stackoverflow.com/questions/24832497 and https://stackoverflow.com/questions/26404951
View popupView = View.inflate(MyParentActivity.this, R.layout.my_popup_layout, null);

// create the popup window
final PopupWindow popupWindow = new PopupWindow(popupView,
        LinearLayout.LayoutParams.WRAP_CONTENT,
        LinearLayout.LayoutParams.WRAP_CONTENT,
        true // lets taps outside the popup also dismiss it
        );

// do something with the stuff in your popup layout, e.g.:
//((TextView)popupView.findViewById(R.id.textview_popup_helloworld))
//      .setText("hello stackoverflow");

// dismiss the popup window when touched
popupView.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            popupWindow.dismiss();
            return true;
        }
});

// show the popup window
// which view you pass in doesn't matter, it is only used for the window token
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
//popupWindow.setOutsideTouchable(false); // doesn't seem to change anything for me

View container = popupWindow.getContentView().getRootView();
if(container != null) {
    WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
    WindowManager.LayoutParams p = (WindowManager.LayoutParams)container.getLayoutParams();
    p.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
    p.dimAmount = 0.3f;
    if(wm != null) {
        wm.updateViewLayout(container, p);
    }
}

So if want to set the value of an environment variable to something different for every build then we can pass these values during build time and we don't need to change our docker file every time.

While ENV, once set cannot be overwritten through command line values. So, if we want to have our environment variable to have different values for different builds then we could use ARG and set default values in our docker file. And when we want to overwrite these values then we can do so using --build-args at every build without changing our docker file.

For more details, you can refer this.

I found out the answer is probably:

A NativeQuery lets you execute native SQL, mapping the results according to your specifications. Such a specification that describes how an SQL result set is mapped to a Doctrine result is represented by a ResultSetMapping.

Source: Native SQL.

Don't forget the awesome

git fetch -p

which fetches and prunes all origins.

To have a constant date format irrespective of the computer settings, you must use 3 different input elements to capture day, month, and year respectively. However, you need to validate the user input to ensure that you have a valid date as shown bellow

<input id="txtDay" type="text" placeholder="DD" />

<input id="txtMonth" type="text" placeholder="MM" />

<input id="txtYear" type="text" placeholder="YYYY" />
<button id="but" onclick="validateDate()">Validate</button>


  function validateDate() {
    var date = new Date(document.getElementById("txtYear").value, document.getElementById("txtMonth").value, document.getElementById("txtDay").value);

    if (date == "Invalid Date") {
        alert("jnvalid date");

    }
}

A percentage value in a height property has a little complication, and the width and height properties actually behave differently to each other. Let me take you on a tour through the specs.

height property:

Let's have a look at what CSS Snapshot 2010 spec says about height:

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'. A percentage height on the root element is relative to the initial containing block. Note: For absolutely positioned elements whose containing block is based on a block-level element, the percentage is calculated with respect to the height of the padding box of that element.

OK, let's take that apart step by step:

The percentage is calculated with respect to the height of the generated box's containing block.

What's a containing block? It's a bit complicated, but for a normal element in the default static position, it's:

the nearest block container ancestor box

or in English, its parent box. (It's well worth knowing what it would be for fixed and absolute positions as well, but I'm ignoring that to keep this answer short.)

So take these two examples:

<div   id="a"  style="width: 100px; height: 200px; background-color: orange">_x000D_
  <div id="aa" style="width: 100px; height: 50%;   background-color: blue"></div>_x000D_
</div>

<div   id="b"  style="width: 100px;              background-color: orange">_x000D_
  <div id="bb" style="width: 100px; height: 50%; background-color: blue"></div>_x000D_
</div>

In this example, the containing block of #aa is #a, and so on for #b and #bb. So far, so good.

The next sentence of the spec for height is the complication I mentioned in the introduction to this answer:

If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.

Aha! Whether the height of the containing block has been specified explicitly matters!

• 50% of height:200px is 100px in the case of #aa
• But 50% of height:auto is auto, which is 0px in the case of #bb since there is no content for auto to expand to

As the spec says, it also matters whether the containing block has been absolutely positioned or not, but let's move on to width.

width property:

So does it work the same way for width? Let's take a look at the spec:

The percentage is calculated with respect to the width of the generated box's containing block.

Take a look at these familiar examples, tweaked from the previous to vary width instead of height:

<div   id="c"  style="width: 200px; height: 100px; background-color: orange">_x000D_
  <div id="cc" style="width: 50%;   height: 100px; background-color: blue"></div>_x000D_
</div>

<div   id="d"  style="            height: 100px; background-color: orange">_x000D_
  <div id="dd" style="width: 50%; height: 100px; background-color: blue"></div>_x000D_
</div>

• 50% of width:200px is 100px in the case of #cc
• 50% of width:auto is 50% of whatever width:auto ends up being, unlike height, there is no special rule that treats this case differently.

Now, here's the tricky bit: auto means different things, depending partly on whether its been specified for width or height! For height, it just meant the height needed to fit the contents*, but for width, auto is actually more complicated. You can see from the code snippet that's in this case it ended up being the width of the viewport.

What does the spec say about the auto value for width?

The width depends on the values of other properties. See the sections below.

Wahey, that's not helpful. To save you the trouble, I've found you the relevant section to our use-case, titled "calculating widths and margins", subtitled "block-level, non-replaced elements in normal flow":

The following constraints must hold among the used values of the other properties:

'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' = width of containing block

OK, so width plus the relevant margin, border and padding borders must all add up to the width of the containing block (not descendents the way height works). Just one more spec sentence:

If 'width' is set to 'auto', any other 'auto' values become '0' and 'width' follows from the resulting equality.

Aha! So in this case, 50% of width:auto is 50% of the viewport. Hopefully everything finally makes sense now!

_Footnotes

_{* At least, as far it matters in this case. spec All right, everything only kind of makes sense now.}

Try range(100,-1,-1), the 3rd argument being the increment to use (documented here).

("range" options, start, stop, step are documented here)

    Object object = new Object();

    // First way
    List objects1 = new ArrayList<Object>();
    objects1.add(object);

    // second way
    List<Object> objects2 = Arrays.asList(object);

    // Third way
    List<Object> objects3 = Collections.singletonList(object);

CONVERT(datetime, '24.04.2012', 104)

Should do the trick. See here for more info: CAST and CONVERT (Transact-SQL)

This is the best way for me:

cat filename.tsv  |
    while read FILENAME
    do
    sudo find /PATH_FROM/  -name "$FILENAME" -maxdepth 4 -exec cp '{}' /PATH_TO/ \; ;
    done

I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;

It works and it's cross browser compatible.

Check out the code below, you probably get a better explanation:

For a Maven project using NetBeans 8.x:

1. Click Run >> Set Project Configuration >> Customise
2. Select Actions
3. Select Run file via main()
4. Set name/value pair to include the arguments.
5. Click OK

An example name/value pair might resemble:

javax.persistence.jdbc.password=PASSWORD

Then run your project:

1. Open and focus the Java class that includes main(...).
2. Press F6 to run the program.

The command line parameters should appear in the Run window.

Note that to obtain the value form with the program, use System.getProperty().

Additional actions for Test file, Run project, and other ways to run the application can have arguments defined. Repeat the steps above for the different actions to accomplish this task.

Per the Bootstrap 4.3 example, in case you're losing your sanity like I did, this is how it actually works:

• All parents of the footer div need to have height: 100% (h-100 class)
• The direct parent of the footer needs to have display: flex (d-flex class)
• The footer needs to have margin-top: auto (mt-auto class)

The problem is that in modern front-end frameworks we often have additional wrappers around these elements.

For example in my case, with Angular, I composed the view from a separate app root, main app component, and footer component - all of which added their custom element to the DOM.

So, to make it work, I had to add classes to these wrapper elements: an additional h-100, moving the d-flex one level down, and moving the mt-auto one level up from the footer (so actually it's not on the footer class anymore, but on my <app-footer> custom element).

you can get the 'date' filter like this:

var today = $filter('date')(new Date(),'yyyy-MM-dd HH:mm:ss Z');

This will give you today's date in format you want.

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

therefore its not possible to hide the Navigation on a tablet permanently with one single call at the beginning of the view creation. It will be hidden, but it will pop up when touching the Screen. So just the second touch to your screen can cause a onClickEvent on your layout. Therefore you need to intercept this call, but i haven't managed it yet, i will update my answer when i found it out. Or do you now the answer already?

Its worth mentioning that the default for an 'Any CPU' compile now checks the 'Prefer 32bit' check box. Being set to AnyCPU, on a 64bit OS with 16gb of RAM can still hit an out of memory exception at 2gb if this is checked.

Simple code that you can write in main(String[] args) function

    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//application will be closed when you close frame
    frame.setSize(800,600);
    frame.setLocation(200,200);

    JFileChooser fc = new JFileChooser();
    if(fc.showOpenDialog(frame) == JFileChooser.APPROVE_OPTION){
        BufferedImage img = ImageIO.read(fc.getSelectedFile());//it must be an image file, otherwise you'll get an exception
        JLabel label = new JLabel();
        label.setIcon(new ImageIcon(img));
        frame.getContentPane().add(label);
    }

    frame.setVisible(true);//showing up the frame

T-SQL supports only AFTER and INSTEAD OF triggers, it does not feature a BEFORE trigger, as found in some other RDBMSs.

I believe you will want to use an INSTEAD OF trigger.

Kiwi Browser is mobile Chromium and allows installing extensions. Install Kiwi and then install "Mini JS console" Chrome extension(just search in Google and install from Chrome extensions website, uBlock also works ;). It will become available in Kiwi menu at the bottom and will show the console output for the current page.

OP's solution to his problem, as he says, has dubious output. That code still shows confusion about representations of time. To clear up this confusion, and make code that won't lead to wrong times, consider this extension of what he did:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
    SimpleDateFormat sdfGMT2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
    sdfGMT2.setTimeZone(TimeZone.getTimeZone("GMT"));

    SimpleDateFormat sdfLocal1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    SimpleDateFormat sdfLocal2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");

    try {
        Date d = new Date();
        String s1 = d.toString();
        String s2 = sdfLocal1.format(d);
        // Store s3 or s4 in database.
        String s3 = sdfGMT1.format(d);
        String s4 = sdfGMT2.format(d);
        // Retrieve s3 or s4 from database, using LOCAL sdf.
        String s5 = sdfLocal1.parse(s3).toString();
        //EXCEPTION String s6 = sdfLocal2.parse(s3).toString();
        String s7 = sdfLocal1.parse(s4).toString();
        String s8 = sdfLocal2.parse(s4).toString();
        // Retrieve s3 from database, using GMT sdf.
        // Note that this is the SAME sdf that created s3.
        Date d2 = sdfGMT1.parse(s3);
        String s9 = d2.toString();
        String s10 = sdfGMT1.format(d2);
        String s11 = sdfLocal2.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

examining values in a debugger:

s1  "Mon Sep 07 06:11:53 EDT 2015" (id=831698113128)    
s2  "2015.09.07 06:11:53" (id=831698114048) 
s3  "2015.09.07 10:11:53" (id=831698114968) 
s4  "2015.09.07 10:11:53 GMT+00:00" (id=831698116112)   
s5  "Mon Sep 07 10:11:53 EDT 2015" (id=831698116944)    
s6  -- omitted, gave parse exception    
s7  "Mon Sep 07 10:11:53 EDT 2015" (id=831698118680)    
s8  "Mon Sep 07 06:11:53 EDT 2015" (id=831698119584)    
s9  "Mon Sep 07 06:11:53 EDT 2015" (id=831698120392)    
s10 "2015.09.07 10:11:53" (id=831698121312) 
s11 "2015.09.07 06:11:53 EDT" (id=831698122256) 

sdf2 and sdfLocal2 include time zone, so we can see what is really going on. s1 & s2 are at 06:11:53 in zone EDT. s3 & s4 are at 10:11:53 in zone GMT -- equivalent to the original EDT time. Imagine we save s3 or s4 in a data base, where we are using GMT for consistency, so we can have times from anywhere in the world, without storing different time zones.

s5 parses the GMT time, but treats it as a local time. So it says "10:11:53" -- the GMT time -- but thinks it is 10:11:53 in local time. Not good.

s7 parses the GMT time, but ignores the GMT in the string, so still treats it as a local time.

s8 works, because now we include GMT in the string, and the local zone parser uses it to convert from one time zone to another.

Now suppose you don't want to store the zone, you want to be able to parse s3, but display it as a local time. The answer is to parse using the same time zone it was stored in -- so use the same sdf as it was created in, sdfGMT1. s9, s10, & s11 are all representations of the original time. They are all "correct". That is, d2 == d1. Then it is only a question of how you want to DISPLAY it. If you want to display what is stored in DB -- GMT time -- then you need to format it using a GMT sdf. Ths is s10.

So here is the final solution, if you don't want to explicitly store with " GMT" in the string, and want to display in GMT format:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));

    try {
        Date d = new Date();
        String s3 = sdfGMT1.format(d);
        // Store s3 in DB.
        // ...
        // Retrieve s3 from database, using GMT sdf.
        Date d2 = sdfGMT1.parse(s3);
        String s10 = sdfGMT1.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

Try to add the class for validation dynamically, when the form has been submitted or the field is invalid. Use the form name and add the 'name' attribute to the input. Example with Bootstrap:

<div class="form-group" ng-class="{'has-error': myForm.$submitted && (myForm.username.$invalid && !myForm.username.$pristine)}">
    <label class="col-sm-2 control-label" for="username">Username*</label>
    <div class="col-sm-10 col-md-9">
        <input ng-model="data.username" id="username" name="username" type="text" class="form-control input-md" required>
    </div>
</div>

It is also important, that your form has the ng-submit="" attribute:

<form name="myForm" ng-submit="checkSubmit()" novalidate>
 <!-- input fields here -->
 ....

  <button type="submit">Submit</button>
</form>

You can also add an optional function for validation to the form:

//within your controller (some extras...)

$scope.checkSubmit = function () {

   if ($scope.myForm.$valid) {
        alert('All good...'); //next step!

   }
   else {
        alert('Not all fields valid! Do something...');
    }

 }

Now, when you load your app the class 'has-error' will only be added when the form is submitted or the field has been touched. Instead of:
!myForm.username.$pristine

You could also use:
myForm.username.$dirty

I am using Google appengine java sdk and was facing similar issue. I had to add

<runtime>java8</runtime>

in appengine-web.xml file to make it work.

I somehow absolutely missed the actual command in the accepted answer, so here it is again, bit more visible in its own paragraph, to see how many people are like me

$ docker history --no-trunc <IMAGE_ID>

I've an image located at here, Using below code. I am able to contgrol any things on the text that i wanted to write (Eg,signature,Transparent Water mark, Text with differnt Font and size).

            Graphics2D g2 = im.createGraphics();
            Font currentFont = g2.getFont();
            Font newFont = currentFont.deriveFont(currentFont.getSize() * 1.4F);
            g2.setFont(newFont);


            Map<TextAttribute, Object> attributes = new HashMap<>();

            attributes.put(TextAttribute.FAMILY, currentFont.getFamily());
            attributes.put(TextAttribute.WEIGHT, TextAttribute.WEIGHT_SEMIBOLD);
            attributes.put(TextAttribute.SIZE, (int) (currentFont.getSize() * 2.8));
            newFont = Font.getFont(attributes);

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            ImageIO.write(im, "png", baos);
            return baos.toByteArray();
        }
    }

In addition to the value you wish to print, the {0} {1}, etc., you can specify a format. For example, {0,4} will be a value that is padded to four spaces.

There are a number of built-in format specifiers, and in addition, you can make your own. For a decent tutorial/list see String Formatting in C#. Also, there is a FAQ here.

Here is another simple way to do it

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID'>Print</a>

Where is @Model.ID is a parameter

And here there is a second example.

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID?param2=ViewBag.P2&param3=ViewBag.P3'>Print</a>

There's no constants in JavaScript, but to declare a literal all you have to do is:

var myString = "Hello World";

I'm not sure what you mean by store them in a resource file; that's not a JavaScript concept.

From a comment by @pamelus on the accepted answer:

You either have to make all interface properties optional (bad) or specify default value also for all required fields (unnecessary boilerplate) or avoid specifying type on defaultProps.

Actually you can use Typescript's interface inheritance. The resulting code is only a little bit more verbose.

interface OptionalGoogleAdsProps {
    format?: string;
    className?: string;
    style?: any;
    scriptSrc?: string
}

interface GoogleAdsProps extends OptionalGoogleAdsProps {
    client: string;
    slot: string;
}

export default class GoogleAds extends React.Component<GoogleAdsProps, void> {
    public static defaultProps: OptionalGoogleAdsProps = {
        format: "auto",
        style: { display: 'block' },
        scriptSrc: "//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"
    };

I wrote this generic type converter. It works with Nullable and standard values, converting between all convertible types - not just string. It handles all sorts of scenarios that you'd expect (default values, null values, other values, etc...)

I've been using this for about a year in dozens of production programs, so it should be pretty solid.

    public static T To<T>(this IConvertible obj)
    {
        Type t = typeof(T);

        if (t.IsGenericType
            && (t.GetGenericTypeDefinition() == typeof(Nullable<>)))
        {
            if (obj == null)
            {
                return (T)(object)null;
            }
            else
            {
                return (T)Convert.ChangeType(obj, Nullable.GetUnderlyingType(t));
            }
        }
        else
        {
            return (T)Convert.ChangeType(obj, t);
        }
    }

    public static T ToOrDefault<T>
                 (this IConvertible obj)
    {
        try
        {
            return To<T>(obj);
        }
        catch
        {
            return default(T);
        }
    }

    public static bool ToOrDefault<T>
                        (this IConvertible obj,
                         out T newObj)
    {
        try
        {
            newObj = To<T>(obj);
            return true;
        }
        catch
        {
            newObj = default(T);
            return false;
        }
    }

    public static T ToOrOther<T>
                           (this IConvertible obj,
                           T other)
    {
        try
        {
            return To<T>(obj);
        }
        catch
        {
            return other;
        }
    }

    public static bool ToOrOther<T>
                             (this IConvertible obj,
                             out T newObj,

                          (this IConvertible obj)
                          where T : class
    {
        try
        {
            return To<T>(obj);
        }
        catch
        {
            return null;
        }
    }

    public static bool ToOrNull<T>
                      (this IConvertible obj,
                      out T newObj)
                      where T : class
    {
        try

You cannot "edit" a default theme, they are "locked in"

However, you can copy it into your own custom theme, with the exact modifications you'd like.

For more info, see these articles: https://code.visualstudio.com/Docs/customization/themes https://code.visualstudio.com/docs/extensions/install-extension#_your-extensions-folder

If all you want to change is the colors for C++ code, you should look at overwriting the c++ support colorizer. For info about that, go here: https://code.visualstudio.com/docs/customization/colorizer

EDIT: The dark theme is found here: https://github.com/Microsoft/vscode/tree/80f8000c10b4234c7b027dccfd627442623902d2/extensions/theme-colorful-defaults

EDIT2: To clarify:

• download this file: https://github.com/Microsoft/vscode/blob/80f8000c10b4234c7b027dccfd627442623902d2/extensions/theme-colorful-defaults/themes/dark_plus.tmTheme
• Modify however you like
• Generate a theme using Yo Code https://code.visualstudio.com/docs/tools/yocode
• Copy that theme into your extension folder. Or, if you feel like sharing, publish it on the VS Code marketplace.

Just install the sdk command line tool(latest) the below in android studio.

That error also shows when the video has played fine and the script will finish but that error always throws because the imshow() will get empty frames after all frames have been consumed.

That is especially the case if you are playing a short (few sec) video file and you don't notice that the video actually played on the background (behind your code editor) and after that the script ends with that error.

FrameLayout is not the better way to do this:

Use RelativeLayout instead. You can position the elements anywhere you like. The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).

Example:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimary"
        app:srcCompat="@drawable/ic_information"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is a text."
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="8dp"
        android:padding="5dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:background="#A000"
        android:textColor="@android:color/white"/>
</RelativeLayout>

Assembly is the smallest unit of deployment of a .net application. It can be a dll or an exe.
There are mainly two types to it:

1. Private Assembly: The dll or exe which is sole property of one application only. It is generally stored in application root folder

2. Public/Shared assembly: It is a dll which can be used by multiple applications at a time. A shared assembly is stored in GAC i.e Global Assembly Cache.

Sounds difficult? Naa....
GAC is simply C:\Windows\Assembly folder where you can find the public assemblies/dlls of all the softwares installed in your PC.

There is also a third and least known type of an assembly: Satellite Assembly.
A Satellite Assembly contains only static objects like images and other non-executable files required by the application.

Hope this helps the readers!

FailedPreconditionError: Attempting to use uninitialized value is one of the most frequent errors related to tensorflow. From official documentation, FailedPreconditionError

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading

Basically to initialize the variable you have 3 options:

• initialize all global variables with tf.global_variables_initializer()
• initialize variables you care about with tf.variables_initializer(list_of_vars). Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
• initialize only one variable with var_name.initializer

I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())

If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables and check is_variable_initialized.

run this query before creating or altering table.

SET @@global.innodb_large_prefix = 1;

this will set max key length to 3072 bytes

You can use pandas.Series.map :

df['col'].map('str{}'.format)

It will apply the word "str" before all your values.

Do you mean elif?

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

Sub stituterangersNEW()
Dim t As Range
Dim x As Range
Dim dify As Boolean
Dim difx As Boolean
Dim time2 As Date

    'You said time1 doesn't change, so I left it in a singe cell.
    'If that is not correct, you will have to play with this some more.
    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

        'Looping through each departure date/time.
        '(Only one row in your example. This can be adjusted if needed.)
        For Each x In Range("B2:E2") 'Change these to match your real ranges.
            'Check to see if our dep time corresponds to
            'the matching column in our output
            If t.Column = x.Column Then
                'If it does, then check to see what our time value is
                If x > 0 Then
                    time2 = x.Value
                    'Apply the change to the output cell.
                    t.Value = time1 - time2
                    'Exit out of this loop and move to the next output cell.
                    Exit For
                End If
            End If
            'If the columns don't match, or the x value is not a time
            'then we'll move to the next dep time (x)
        Next x
    Next t

End Sub

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

There are a few steps to see the tables in an SQLite database:

1. List the tables in your database:

   .tables
   

2. List how the table looks:

   .schema tablename
   

3. Print the entire table:

   SELECT * FROM tablename;
   

4. List all of the available SQLite prompt commands:

   .help

                var h = today.getHours();

Use self.view.tintColor from a view controller, or self.tintColor from a UIView subclass.

It's simpler if you pass an event parameter like this:

<a href="#" onclick="yes_js_login(event);">link</a>

function yes_js_login(e) {
    e.stopImmediatePropagation();
}

Google Chrome has a two ways to check for unused CSS.

1. Audit Tab: > Right Click + Inspect Element on the page, find the "Audit" tab, and run the audit, making sure "Web Page Performance" is checked.

Lists all unused CSS tags - see image below.

Update: - - - - - - - - - - - - - - OR - - - - - - - - - - - - - -

2. Coverage Tab: > Right Click + Inspect Element on the page, find the three dots on the far right (circled in image) and open Console Drawer (or hit Esc), finally click the three dots left side in the drawer (circled in image) to open Coverage tool.

Chrome launched a tool to see unused CSS and JS - Chrome 59 Update Allows you to start and stop a recording (red square in image) to allow better coverage of a user experience on the page.

Shows all used and unused CSS/JS in the files - see image below.

A simple example:

public class Test extends Thread {
    public synchronized void run() {
        for (int i = 0; i <= 10; i++) {
            System.out.println("i::"+i);
        }
    }

    public static void main(String[] args) {
        Test obj = new Test();

        Thread t1 = new Thread(obj);
        Thread t2 = new Thread(obj);
        Thread t3 = new Thread(obj);

        t1.start();
        t2.start();
        t3.start();
    }
}

A fourth option to those you mention are binary files. Although that sounds arcane and difficult, it's really easy with the serialization API in .NET.

Whether you choose binary or XML files, you can use the same serialization API, although you would use different serializers.

To binary serialize a class, it must be marked with the [Serializable] attribute or implement ISerializable.

You can do something similar with XML, although there the interface is called IXmlSerializable, and the attributes are [XmlRoot] and other attributes in the System.Xml.Serialization namespace.

If you want to use a relational database, SQL Server Compact Edition is free and very lightweight and based on a single file.

I am not quite sure what you need, but I would use something like this:

#!/usr/bin/env ruby

until ARGV.empty? do
  puts "From arguments: #{ARGV.shift}"
end

while a = gets
  puts "From stdin: #{a}"
end

Note that because ARGV array is empty before first gets, Ruby won't try to interpret argument as text file from which to read (behaviour inherited from Perl).

If stdin is empty or there is no arguments, nothing is printed.

Few test cases:

$ cat input.txt | ./myprog.rb
From stdin: line 1
From stdin: line 2

$ ./myprog.rb arg1 arg2 arg3
From arguments: arg1
From arguments: arg2
From arguments: arg3
hi!
From stdin: hi!

One thing that I have to add is that there is no reference in C.

Secondly, this is the language syntax convention. & - is an address operator but it also mean a reference - all depends on usa case

If there was some "reference" keyword instead of & you could write

int CDummy::isitme (reference CDummy param)

but this is C++ and we should accept it advantages and disadvantages...

You are doing it right. The empty code block is what is causing your issue. It's not the condition structure :)

You can do it in two ways, choose what suits your requirement:

Method I.) Replacing using line number. You can use built-in function enumerate() in this case:

First, in read mode get all data in a variable

with open("your_file.txt",'r') as f:
    get_all=f.readlines()

Second, write to the file (where enumerate comes to action)

with open("your_file.txt",'w') as f:
    for i,line in enumerate(get_all,1):         ## STARTS THE NUMBERING FROM 1 (by default it begins with 0)    
        if i == 2:                              ## OVERWRITES line:2
            f.writelines("Mage\n")
        else:
            f.writelines(line)

Method II.) Using the keyword you want to replace:

Open file in read mode and copy the contents to a list

with open("some_file.txt","r") as f:
    newline=[]
    for word in f.readlines():        
        newline.append(word.replace("Warrior","Mage"))  ## Replace the keyword while you copy.  

"Warrior" has been replaced by "Mage", so write the updated data to the file:

with open("some_file.txt","w") as f:
    for line in newline:
        f.writelines(line)

This is what the output will be in both cases:

Dan                   Dan           
Warrior   ------>     Mage       
500                   500           
1                     1   
0                     0           

In real life where you encounter systems already written and adding indexes to tables then drastically slows down the data loading of a 14gig data table, you are sometime forced to used WITH NOLOCK on your reports and end of month proessing so that the aggregate funtions (sum, count etc) do not do row, page, table locking and deteriate the overall performance. Easy to say in a new system never use WITH NOLOCK and use indexes - but adding indexes severly downgrades data loading, and when I'm then told, well, alter the code base to delete indexes, then bulk load then recreate the indexes - which is all well and good, if you are developing a new system. But Not when you have a system already in place.

types.Values.ToList().IndexOf("one");

Values.ToList() converts your dictionary values into a List of objects. IndexOf("one") searches your new List looking for "one" and returns the Index which would match the index of the Key/Value pair in the dictionary.

This method does not care about the dictionary keys, it simply returns the index of the value that you are looking for.

Keep in mind there may be more than one "one" value in your dictionary. And that is the reason there is no "get key" method.

I found a more generic way to discover it:

  int[] location = new int[2];
  mainView.getLocationOnScreen(location);
  int toolbarHeight = location[1];

where 'mainView' is the root view of your layout.

The idea is basically get the Y position of the mainView as it is set right below the ActionBar (or Toolbar).

Posix is more as an OS, it is an "OS standard". You can imagine it as an imaginary OS, which actually doesn't exist, but it has a documentation. These papers are the "posix standard", defined by the IEEE, which is the big standard organization of the USA. The OSes implementing this specification are "Posix-compliant".

Government regulations prefer Posix-compliant solutions in their investments, thus being Posix-compliant has a significant financial advantage, particularly for the big IT companies of the USA.

The reward for an OS being fully posix compliant, that it is a guarantee that it will compile and run all Posix-compliant applications seamlessly.

Linux is the most well-known one. OSX, Solaris, NetBSD and Windows NT play here as well. Free- and OpenBSD are only "nearly" Posix-compliant. The posix-compliance of the WinNT is only a pseudo-solution to avoid this government regulation above.

printf(...) is equivalent to fprintf(stdout,...).

fprintf is used to output to stream.

sprintf(buffer,...) is used to format a string to a buffer.

Note there is also vsprintf, vfprintf and vprintf

DateTime.Parse

Syntax:

DateTime.Parse(String value)
DateTime.Parse(String value, IFormatProvider provider)
DateTime.Parse(String value, IFormatProvider provider, DateTypeStyles styles)

Example:

string value = "1 January 2019";
CultureInfo provider = new CultureInfo("en-GB");
DateTime.Parse(value, provider, DateTimeStyles.NoCurrentDateDefault););

• Value: string representation of date and time.
• Provider: object which provides culture specific info.
• Styles: formatting options that customize string parsing for some date and time parsing methods. For instance, AllowWhiteSpaces is a value which helps to ignore all spaces present in string while it parse.

It's also worth remembering DateTime is an object that is stored as number internally in the framework, Format only applies to it when you convert it back to string.

• Parsing converting a string to the internal number type.

• Formatting converting the internal numeric value to a readable string.

I recently had an issue where I was trying to convert a DateTime to pass to Linq what I hadn't realised at the time was format is irrelevant when passing DateTime to a Linq Query.

DateTime SearchDate = DateTime.Parse(searchDate);
applicationsUsages = applicationsUsages.Where(x => DbFunctions.TruncateTime(x.dateApplicationSelected) == SearchDate.Date);

I don't know if you can change the size at runtime but you can allocate the size at runtime. Try using this code:

class MyClass {
    void myFunction () {
        Scanner s = new Scanner (System.in);
        int myArray [];
        int x;

        System.out.print ("Enter the size of the array: ");
        x = s.nextInt();

        myArray = new int[x];
    }
}

this assigns your array size to be the one entered at run time into x.

No, abstract class can never be instantiated.

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

You could alter your CSS to render them less obtrusively, e.g.

div p,
div br {
    display: inline;
}

http://jsfiddle.net/zG9Ax/

or - as my commenter points out:

div br {
    display: none;
}

but then to achieve the example of what you want, you'll need to trim the p down, so:

div br {
    display: none;
}
div p {
    padding: 0;
    margin: 0;
}

Yes. We will use Java 8 soon!

We've decided to add support for Java 8 language features directly into the current javac and dx set of tools, and deprecate the Jack toolchain. With this new direction, existing tools and plugins dependent on the Java class file format should continue to work. Moving forward, Java 8 language features will be natively supported by the Android build system. We're aiming to launch this as part of Android Studio in the coming weeks, and we wanted to share this decision early with you.

https://android-developers.googleblog.com/2017/03/future-of-java-8-language-feature.html

There have been methodologies in all languages advocating for use of a single return statement in any function. However impossible it may be in certain code, some people do strive for that, however, it may end up making your code more complex (as in more lines of code), but on the other hand, somewhat easier to follow (as in logic flow).

This will not mess up garbage collection in any way!!

The better way to do it is to set a boolean value, if you want to listen to him.

boolean flag = false;
for(int i=0; i<array.length; ++i){
    if(array[i] == valueToFind) {
        flag = true;
        break;
    }
}
return flag;

I would suggest using MDO's http://getpreboot.com/ instead. As of v2, preboot back ports the LESS mixins/variables used to create the Bootstrap 3.0 Grid System and is much more light weight than using the CSS generator. In fact, if you only include preboot.less there is NO overhead because the entire file is made up of mixins/variables and therefore are only used in pre-compilation and not the final output.

GUIDs are 128bits, or

0 through ffffffffffffffffffffffffffffffff (hex) or 
0 through 340282366920938463463374607431768211455 (decimal) or 
0 through 11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111 (binary, base 2) or 
0 through 91"<b.PX48m!wVmVA?1y (base 95)

So yes, min 20 characters long, which is actually wasting more than 4.25 bits, so you can be just as efficient using smaller bases than 95 as well; base 85 being the smallest possible one that still fits into 20 chars:

0 through -r54lj%NUUO[Hi$c2ym0 (base 85, using 0-9A-Za-z!"#$%&'()*+,- chars)

:-)

For Mac, this worked perfectly:

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Yes. Look at http://jerrywickey.com/test/testJerrysLibrary.php

It gives sample code examples for RSA encryption and decryption in PHP as well as RSA encryption in javascript.

If you want to encrypt text instead of just base 10 numbers, you'll also need a base to base conversion. That is convert text to a very large number. Text is really just writing in base 63. 26 lowercase letters plus 26 uppercase + 10 numerals + space character. The code for that is below also.

The $GETn parameter is a file name that holds keys for the cryption functions. If you don't figure it out, ask. I'll help.

I actually posted this whole encryption library yesterday, but Brad Larson a mod, killed it and said this kind of stuff isn't really what Stack Overflow is about. But you can still find all the code examples and the whole function library to carry out client/server encryption decryption for AJAX at the link above.

function RSAencrypt( $num, $GETn){
    if ( file_exists( 'temp/bigprimes'.hash( 'sha256', $GETn).'.php')){

This work for me

from flask import Flask
from flask import Response

app = Flask(__name__)

@app.route("/")
def home():
    return Response(headers={'Access-Control-Allow-Origin':'*'})

if __name__ == "__main__":
    app.run()

To figure out what is the difference between before_action and before_filter, we should understand the difference between action and filter.

An action is a method of a controller to which you can route to. For example, your user creation page might be routed to UsersController#new - new is the action in this route.

Filters run in respect to controller actions - before, after or around them. These methods can halt the action processing by redirecting or set up common data to every action in the controller.

Rails 4 –> _action

Rails 3 –> _filter

You can use CSS:

p.capitalize {text-transform:capitalize;}

Update (JS Solution):

Based on Kamal Reddy's comment:

document.getElementById("myP").style.textTransform = "capitalize";

If it's a class that you can modify, you could declare a class variable static java.util.concurrent.atomic.AtomicInteger nextInstanceId. (You'll have to give it an initial value in the obvious way.) Then declare an instance variable int instanceId = nextInstanceId.getAndIncrement().

The other answers were incomplete for me. I started from @Vladimir Novopashin answer and modified it. Here are the things, that I needed and bug I found:

• Support for file
• Support for array
• Bug: File inside complex object needs to be added with .prop instead of [prop]. For example, formData.append('photos[0][file]', file) didn't work on google chrome, while formData.append('photos[0].file', file) worked
• Ignore some properties in my object

The following code should work on IE11 and evergreen browsers.

function objectToFormData(obj, rootName, ignoreList) {
    var formData = new FormData();

    function appendFormData(data, root) {
        if (!ignore(root)) {
            root = root || '';
            if (data instanceof File) {
                formData.append(root, data);
            } else if (Array.isArray(data)) {
                for (var i = 0; i < data.length; i++) {
                    appendFormData(data[i], root + '[' + i + ']');
                }
            } else if (typeof data === 'object' && data) {
                for (var key in data) {
                    if (data.hasOwnProperty(key)) {
                        if (root === '') {
                            appendFormData(data[key], key);
                        } else {
                            appendFormData(data[key], root + '.' + key);
                        }
                    }
                }
            } else {
                if (data !== null && typeof data !== 'undefined') {
                    formData.append(root, data);
                }
            }
        }
    }

    function ignore(root){
        return Array.isArray(ignoreList)
            && ignoreList.some(function(x) { return x === root; });
    }

    appendFormData(obj, rootName);

    return formData;

I know this question is quite old, but here's a library that encapsulates the ProcessBuilder api.

I found 2 quick options to fix this:

1. Just input in search "Preview" and it will show you a single result. Just click on it and preview appears again :)
2. Pull the right-side line and window will appear. It's kinda resize.

Happy coding!

{{ }} tells the template to print the value, this won't work in expressions like you're trying to do. Instead, use the {% set %} template tag and then assign the value the same way you would in normal python code.

{% set testing = 'it worked' %}
{% set another = testing %}
{{ another }}

Result:

it worked

Or simply use the JFreechart library - http://www.jfree.org/jfreechart/ .

Use something like this:

page1.php

<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>

Any other PHP page:

<?php
session_start();
echo $_SESSION['myValue'];
?>

A few notes to keep in mind though: You need to call session_start() BEFORE any output, HTML, echos - even whitespace.

You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.

The setting of the variable itself can be done in one of a number of ways:

$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];

And if you want to check if the variable is set before getting a potential error, use something like this:

if(!empty($_SESSION['myValue'])
{
    echo $_SESSION['myValue'];
}
else
{
    echo "Session not set yet.";
}

According to the manual on json_encode the method can return a non-string (false):

Returns a JSON encoded string on success or FALSE on failure.

When this happens echo json_encode($data) will output the empty string, which is invalid JSON.

json_encode will for instance fail (and return false) if its argument contains a non UTF-8 string.

This error condition should be captured in PHP, for example like this:

<?php
header("Content-Type: application/json");

// Collect what you need in the $data variable.

$json = json_encode($data);
if ($json === false) {
    // Avoid echo of empty string (which is invalid JSON), and
    // JSONify the error message instead:
    $json = json_encode(["jsonError" => json_last_error_msg()]);
    if ($json === false) {
        // This should not happen, but we go all the way now:
        $json = '{"jsonError":"unknown"}';
    }
    // Set HTTP response status code to: 500 - Internal Server Error
    http_response_code(500);
}
echo $json;
?>

Then the receiving end should of course be aware that the presence of the jsonError property indicates an error condition, which it should treat accordingly.

In production mode it might be better to send only a generic error status to the client and log the more specific error messages for later investigation.

Read more about dealing with JSON errors in PHP's Documentation.

In Windows 10 both the command prompt and the powershell prompt can be found via the menu bar, for both non-admin and admin. These options will have its folder set to the currently selected folder from the explorer.

For the Swedish version at least, the powershell is opened with Alt F+I. For an administrator powershell it's Alt F+S+P.

If those are not the correct characters you can press and hold the Alt key to see the correct characters. there will be a character overlaying the menu item for each step.
