Override toString() method in Student class as below:

   @Override
   public String toString() {
        return ("StudentName:"+this.getStudentName()+
                    " Student No: "+ this.getStudentNo() +
                    " Email: "+ this.getEmail() +
                    " Year : " + this.getYear());
   }

To write a newline use \n not /n the latter is just a slash and a n

There are a couple of ways to address your problem, however this is probably the most straightforward:

Your main method is static, so it does not have access to instance members (isLeapYear field and isLeapYear method. One approach to rectify this is to make both the field and the method static as well:

static boolean isLeapYear;
/* (snip) */
public static boolean isLeapYear(int year)
{
  /* (snip) */
}

Lastly, you're not actually calling your isLeapYear method (which is why you're not seeing any results). Add this line after int year = kboard.nextInt();:

isLeapYear(year);

That should be a start. There are some other best practices you could follow but for now just focus on getting your code to work; you can refactor later.

IE9 no longer supports triggering the Print() VBScript by calling window.print() like IE7 and IE8 do, and thus window.print() will now always trigger the print dialog in IE9.

The fix is pretty simple. You just need to call Print() itself, instead of window.print() in the onclick event.

I've described the fix in more detail in an answer to another question, with a working code example sporting slightly updated HTML syntax (as much as possible while still tested as working code).

You can find that sample code here:

Bypass Printdialog in IE9

I finally figured out the regex to change these all in old Python2 example scripts. Otherwise use 2to3.py.

Try it out on Regexr.com, doesn't work in NP++(?):

find:     (?<=print)( ')(.*)(')
replace: ('$2')

for variables:

(?<=print)( )(.*)(\n)
('$2')\n

for label and variable:

(?<=print)( ')(.*)(',)(.*)(\n)
('$2',$4)\n

It looks like the problem had been resolved with the latest Chrome update... I'm running the Chrome Version 36.0.1964.4 dev-m.

I was limited too warning the user from closing print preview window by doing the following:

if(navigator.userAgent.toLowerCase().indexOf('chrome') > -1){   // Chrome Browser Detected?
    window.PPClose = false;                                     // Clear Close Flag
    window.onbeforeunload = function(){                         // Before Window Close Event
        if(window.PPClose === false){                           // Close not OK?
            return 'Leaving this page will block the parent window!\nPlease select "Stay on this Page option" and use the\nCancel button instead to close the Print Preview Window.\n';
        }
    }                   
    window.print();                                             // Print preview
    window.PPClose = true;                                      // Set Close Flag to OK.
}

Now the warning is no longer coming up after the Chrome update.

all these answers has the problem, that's always stretching the image to pagesize and cuts off some content at trying this.
Found a little bit easier way.

My own solution only stretch(is this the right word?) if the image is to large, can use multiply copies and pageorientations.

                PrintDialog dlg = new PrintDialog();

            if (dlg.ShowDialog() == true)
            {
                BitmapImage bmi = new BitmapImage(new Uri(strPath));

                Image img = new Image();
                img.Source = bmi;

                if (bmi.PixelWidth < dlg.PrintableAreaWidth ||
                           bmi.PixelHeight < dlg.PrintableAreaHeight)
                {
                    img.Stretch = Stretch.None;
                    img.Width = bmi.PixelWidth;
                    img.Height = bmi.PixelHeight;
                }


                if (dlg.PrintTicket.PageBorderless == PageBorderless.Borderless)
                {
                    img.Margin = new Thickness(0);
                }
                else
                {
                    img.Margin = new Thickness(48);
                }
                img.VerticalAlignment = VerticalAlignment.Top;
                img.HorizontalAlignment = HorizontalAlignment.Left;

                for (int i = 0; i < dlg.PrintTicket.CopyCount; i++)
                {
                    dlg.PrintVisual(img, "Print a Image");
                }
            }

2016 update:

Well, I got this problem, when I had

overflow:hidden

on my div.

After I made

@media print {
   div {
      overflow:initial !important
   }
}

everything became just fine and perfect

I believe that Python 3.1 will print them nicer by default, without any code changing. But that is useless if you use any extensions that haven't been updated to work with Python 3.1

If you set the margin for a page using the code below the header and footers are omitted from the printed page. I have tested this in FireFox and Chrome.

<style media="print">
 @page {
  size: auto;
  margin: 0;
       }
</style>

Always check the standard libraries first.

import java.util.Arrays;

Then try:

System.out.println(Arrays.toString(array));

or if your array contains other arrays as elements:

System.out.println(Arrays.deepToString(array));

Just wrap window.close by onafterprint event handler, it worked for me

printWindow.print();
printWindow.onafterprint = () => printWindow.close();

I tried to solve this problem once, but all my research led me towards ActiveX controls/plug-ins. There is no trick that the browsers (3 years ago anyway) permitted to change any print settings (number of copies, paper size).

I put my efforts into warning the user carefully that they needed to select "landscape" when the browsers print dialog appeared. I also created a "print preview" page, which worked much better than IE6's did! Our application had very wide tables of data in some reports, and the print preview made it clear to the users when the table would spill off the right-edge of the paper (since IE6 couldnt cope with printing on 2 sheets either).

And yes, people are still using IE6 even now.

Try this code, works 100% for me:
FOR Landscape:

<head>
<style type="text/css">

@page{
  size: auto A4 landscape;
  margin: 3mm;
}

</style>
</head>

FOR Portait:

<head>
<style type="text/css">

@page{
  size: auto;
  margin: 3mm;
}

</style>
</head>

Updated, Simple Solution

@media print {
   body {
       display: table;
       table-layout: fixed;
       padding-top: 2.5cm;
       padding-bottom: 2.5cm;
       height: auto;
   }
}

Old Solution

Create section with each page, and use the below code to adjust margins, height and width.

If you are printing A4 size.

Then user

Size : 8.27in and 11.69 inches

@page Section1 {
    size: 8.27in 11.69in; 
    margin: .5in .5in .5in .5in; 
    mso-header-margin: .5in; 
    mso-footer-margin: .5in; 
    mso-paper-source: 0;
}



div.Section1 {
    page: Section1;
} 

then create a div with all your content in it.

<div class="Section1"> 
    type your content here... 
</div>

A simple way to add the tab would be to use the \t tag.

print '{0} \t {1}'.format(count, conv)

This answer is based on the 2nd tip from this blog post: 28 Jupyter Notebook tips, tricks and shortcuts

You can add the following code to the top of your notebook

from IPython.core.interactiveshell import InteractiveShell
InteractiveShell.ast_node_interactivity = "all"

This tells Jupyter to print the results for any variable or statement on it’s own line. So you can then execute a cell solely containing

df1
df2

and it will "print out the beautiful tables for both datasets".

import sys
import time

a = 0  
for x in range (0,3):  
    a = a + 1  
    b = ("Loading" + "." * a)
    # \r prints a carriage return first, so `b` is printed on top of the previous line.
    sys.stdout.write('\r'+b)
    time.sleep(0.5)
print (a)

Note that you might have to run sys.stdout.flush() right after sys.stdout.write('\r'+b) depending on which console you are doing the printing to have the results printed when requested without any buffering.

I had to deal with wkhtmltopdf too.

I'm using Bootstrap 3.3.7 as Framework and need to avoid page break on .row element.

I did the job using those settings:

.myContainer {
    display: grid;
    page-break-inside: avoid;
}

No need to wrap in @media print

It's been a long time since I've worked in a Windows environment, but I would suggest that you look at using WMI.

we can find length of array by using array_name.length attribute

int [] i = i.length;

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Test</title>
<style type="text/css">
    table { page-break-inside:auto }
    tr    { page-break-inside:avoid; page-break-after:auto }
    thead { display:table-header-group }
    tfoot { display:table-footer-group }
</style>
</head>
<body>
    <table>
        <thead>
            <tr><th>heading</th></tr>

        </tfoot>
        <tbody>
        <tr>
            <td>x</td>
        </tr>
        <tr>
            <td>x</td>
        </tr>
        <!-- 500 more rows -->
        <tr>
            <td>x</td>
        </tr>
    </tbody>
    </table>
</body>
</html>

This answer goes over some of the cases that have not been discussed above.
The return statement allows you to terminate the execution of a function before you reach the end. This causes the flow of execution to immediately return to the caller.

In line number 4:

def ret(n):
    if n > 9:
         temp = "two digits"
         return temp     #Line 4        
    else:
         temp = "one digit"
         return temp     #Line 8
    print("return statement")
ret(10)

After the conditional statement gets executed the ret() function gets terminated due to return temp (line 4). Thus the print("return statement") does not get executed.

Output:

two digits   

This code that appears after the conditional statements, or the place the flow of control cannot reach, is the dead code.

Returning Values
In lines number 4 and 8, the return statement is being used to return the value of a temporary variable after the condition has been executed.

To bring out the difference between print and return:

def ret(n):
    if n > 9:
        print("two digits")
        return "two digits"           
    else :
        print("one digit")
        return "one digit"        
ret(25)

Output:

two digits
'two digits'

This is realy old post but here is one my update what I made using correct answer. My solution also use jQuery.

Point of this is to use proper print view, include all stylesheets for the proper formatting and also to be supported in the most browsers.

function PrintElem(elem, title, offset)
{
    // Title constructor
    title = title || $('title').text();
    // Offset for the print
    offset = offset || 0;

    // Loading start
    var dStart = Math.round(new Date().getTime()/1000),
        $html = $('html');
        i = 0;

    // Start building HTML
    var HTML = '<html';

    if(typeof ($html.attr('lang')) !== 'undefined') {
        HTML+=' lang=' + $html.attr('lang');
    }

    if(typeof ($html.attr('id')) !== 'undefined') {
        HTML+=' id=' + $html.attr('id');
    }

    if(typeof ($html.attr('xmlns')) !== 'undefined') {
        HTML+=' xmlns=' + $html.attr('xmlns');
    }

    // Close HTML and start build HEAD
    HTML+='><head>';

    // Get all meta tags
    $('head > meta').each(function(){
        var $this = $(this),
            $meta = '<meta';

        if(typeof ($this.attr('charset')) !== 'undefined') {
            $meta+=' charset=' + $this.attr('charset');
        }

        if(typeof ($this.attr('name')) !== 'undefined') {
            $meta+=' name=' + $this.attr('name');
        }

        if(typeof ($this.attr('http-equiv')) !== 'undefined') {
            $meta+=' http-equiv=' + $this.attr('http-equiv');
        }

        if(typeof ($this.attr('content')) !== 'undefined') {
            $meta+=' content=' + $this.attr('content');
        }

        $meta+=' />';

        HTML+= $meta;
        i++;

    }).promise().done(function(){

        // Insert title
        HTML+= '<title>' + title  + '</title>';

        // Let's pickup all CSS files for the formatting
        $('head > link[rel="stylesheet"]').each(function(){
            HTML+= '<link rel="stylesheet" href="' + $(this).attr('href') + '" />';
            i++;
        }).promise().done(function(){
            // Print setup
            HTML+= '<style>body{display:none;}@media print{body{display:block;}}</style>';

            // Finish HTML
            HTML+= '</head><body>';
            HTML+= '<h1 class="text-center mb-3">' + title  + '</h1>';
            HTML+= elem.html();
            HTML+= '</body></html>';

            // Open new window
            var printWindow = window.open('', 'PRINT', 'height=' + $(window).height() + ',width=' + $(window).width());
            // Append new window HTML
            printWindow.document.write(HTML);

            printWindow.document.close(); // necessary for IE >= 10
            printWindow.focus(); // necessary for IE >= 10*/
console.log(printWindow.document);
            /* Make sure that page is loaded correctly */
            $(printWindow).on('load', function(){                   
                setTimeout(function(){
                    // Open print
                    printWindow.print();

                    // Close on print
                    setTimeout(function(){
                        printWindow.close();
                        return true;
                    }, 3);

                }, (Math.round(new Date().getTime()/1000) - dStart)+i+offset);
            });
        });
    });
}

Later you simple need something like this:

$(document).on('click', '.some-print', function() {
    PrintElem($(this), 'My Print Title');
    return false;
});

Try it.

The way you're writing your print statement is unnecessarily verbose. There's no need to separate the newline into its own string. This is sufficient.

print "hello.\n";

This realization will probably make your coding easier in general.

In addition to using use feature "say" or use 5.10.0 or use Modern::Perl to get the built in say feature, I'm going to pimp perl5i which turns on a lot of sensible missing Perl 5 features by default.

Regarding your need to 'print directly from datagridview', check out this article on CodeProject:

The DataGridViewPrinter Class

There are a number of similar articles but I've had luck with the one I linked.

Use repr:

a = "Hello\tWorld\nHello World"
print(repr(a))
# 'Hello\tWorld\nHello World'

Note you do not get \s for a space. I hope that was a typo...?

But if you really do want \s for spaces, you could do this:

print(repr(a).replace(' ',r'\s'))

I'm going out on a limb here , since your question was not very detailed, that a) your receipt printer is a thermal printer that needs raw data, b) that "from javascript" you are talking about printing from the web browser and c) that you do not have access to send raw data from browser

Here is a Java Applet that solves all that for you , if I'm correct about those assumptions then you need either Java, Flash, or Silverlight http://code.google.com/p/jzebra/

Just try:

print("Total score for", name, "is", score)

Nice and simple:

console.log("object: %O", obj)

i wrote a small function.. but works for me

def conv(strng):
    k=strng
    k=k.replace('\a','\\a')
    k=k.replace('\b','\\b')
    k=k.replace('\f','\\f')
    k=k.replace('\n','\\n')
    k=k.replace('\r','\\r')
    k=k.replace('\t','\\t')
    k=k.replace('\v','\\v')
    return k

You can adjust pandas print options with set_printoptions.

However this will not work in all cases as pandas detects your console width and it will only use to_string if the output fits in the console (see the docstring of set_printoptions). In this case you can explicitly call to_string as answered by BrenBarn.

With version 0.10 the way wide dataframes are printed changed:

If you want to print the array like you print a 2D list in Python:

#include <stdio.h>

int main()
{
  int i, j;
  int my_array[3][3] = {{10, 23, 42}, {1, 654, 0}, {40652, 22, 0}};
  for(i = 0; i < 3; i++)
  {
      if (i == 0) {
          printf("[");
      }
      printf("[");
      for(j = 0; j < 3; j++)
      {
         printf("%d", my_array[i][j]);
         if (j < 2) {
             printf(", ");
         }
      }
    printf("]");
    if (i == 2) {
        printf("]");
    }

    if (i < 2) {
        printf(", ");
    }
  }
  return 0;
}

Output will be:

[[10, 23, 42], [1, 654, 0], [40652, 22, 0]]

The way we typically handle printing is to just open the new window with everything in it that needs to be sent to the printer. Then we have the user actually click on their browsers Print button.

This has always been acceptable in the past, and it sidesteps the security restrictions that Chilln is talking about.

None of the answers worked with me, but after reading all of them, I figured out what was the issue in my case I have 1 Html page that I want to print but it was printing with it an extra white blank page. I am using AdminLTE a bootstrap 3 theme for the page of the report to print and in it the footer tag I wanted to place this text to the bottom right of the page:

Printed by Mr. Someone

I used jquery to put that text instead of the previous "Copy Rights" footer with

$("footer").html("Printed by Mr. Someone");

and by default in the theme the tag footer uses the class .main-footer which has the attributes

padding: 15px;
border-top: 1px solid 

that caused an extra white space, so after knowing the issue, I had different options, and the best option was to use

$( "footer" ).removeClass( "main-footer" );

Just in that specific page

In Python 3.x, you can use the end argument to the print() function to prevent a newline character from being printed:

print("Nope, that is not a two. That is a", end="")

In Python 2.x, you can use a trailing comma:

print "this should be",
print "on the same line"

You don't need this to simply print a variable, though:

print "Nope, that is not a two. That is a", x

Note that the trailing comma still results in a space being printed at the end of the line, i.e. it's equivalent to using end=" " in Python 3. To suppress the space character as well, you can either use

from __future__ import print_function

to get access to the Python 3 print function or use sys.stdout.write().

You can try wx library. It's a cross platform UI library. Here you can find the printing tutorial: https://web.archive.org/web/20160619163747/http://wiki.wxpython.org/Printing

Use:

function console_log($data) {
    $bt = debug_backtrace();
    $caller = array_shift($bt);

    if (is_array($data))
        $dataPart = implode(',', $data);
    else
        $dataPart = $data;

    $toSplit = $caller['file'])) . ':' .
               $caller['line'] . ' => ' . $dataPart

    error_log(end(split('/', $toSplit));
}

As Chris Lutz mentioned, this is defined by the __repr__ method in your class.

From the documentation of repr():

For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets that contains the name of the type of the object together with additional information often including the name and address of the object. A class can control what this function returns for its instances by defining a __repr__() method.

Given the following class Test:

class Test:
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def __repr__(self):
        return "<Test a:%s b:%s>" % (self.a, self.b)

    def __str__(self):
        return "From str method of Test: a is %s, b is %s" % (self.a, self.b)

..it will act the following way in the Python shell:

>>> t = Test(123, 456)
>>> t
<Test a:123 b:456>
>>> print repr(t)
<Test a:123 b:456>
>>> print(t)
From str method of Test: a is 123, b is 456
>>> print(str(t))
From str method of Test: a is 123, b is 456

If no __str__ method is defined, print(t) (or print(str(t))) will use the result of __repr__ instead

If no __repr__ method is defined then the default is used, which is pretty much equivalent to..

def __repr__(self):
    return "<%s instance at %s>" % (self.__class__.__name__, id(self))

That's the best I guess:

   for (int[] row : matrix){
    System.out.println(Arrays.toString(row));
   }

According to this SO link you can print a specific div with

w=window.open();
w.document.write(document.getElementsByClassName('report_left_inner')[0].innerH??TML);
w.print();
w.close();

Looks like the usual suspects like pdfsharp and migradoc are not able to do that (pdfsharp only if you have Acrobat (Reader) installed).

I found here

https://vishalsbsinha.wordpress.com/2014/05/06/how-to-programmatically-c-net-print-a-pdf-file-directly-to-the-printer/

code ready for copy/paste. It uses the default printer and from what I can see it doesn't even use any libraries, directly sending the pdf bytes to the printer. So I assume the printer also needs to support it, on one 10 year old printer I tested this it worked flawlessly.

Most other approaches - without commercial libraries or applications - require you to draw yourself in the printing device context. Doable but will take a while to figure it out and make it work across printers.

You can also use

top.iframeName.print();

or

parent.iframeName.print();

You should put the print function in your view-details.php file and call it once the file is loaded, by either using

<body onload="window.print()"> 

or

$(document).ready(function () { 
  window.print(); 
});

For lazy people:

Without installing any additional library, it is compatible with every single terminal i know.

Class approach:

First do import config as cfg.

clipped is dataframe.

            #### HEADER: ####
            print('{0:<23} {1:>24} {2:>26} {3:>26} {4:>11} {5:>11}'.format('Road name','Classification','Function','Form of road','Length','Distance') )

            #### Now row by row: ####
            for index, row in clipped.iterrows():
                rdName      = self.colorize(row['name1'],cfg.Green)
                rdClass     = self.colorize(row['roadClassification'],cfg.LightYellow)
                rdFunction  = self.colorize(row['roadFunction'],cfg.Yellow)
                rdForm      = self.colorize(row['formOfWay'],cfg.LightBlue)
                rdLength    = self.colorize(row['length'],cfg.White)
                rdDistance  = self.colorize(row['distance'],cfg.LightCyan)
                print('{0:<30} {1:>35} {2:>35} {3:>35} {4:>20} {5:>20}'.format(rdName,rdClass,rdFunction,rdForm,rdLength,rdDistance) )

Meaning of {0:<30} {1:>35} {2:>35} {3:>35} {4:>20} {5:>20}:

0, 1, 2, 3, 4, 5 -> columns, there are 6 in total in this case

30, 35, 20 -> width of column (note that you'll have to add length of \033[96m - this for Python is a string as well), just experiment :)

>, < -> justify: right, left (there is = for filling with zeros as well)

What is in config.py:

#colors
ResetAll = "\033[0m"

Bold       = "\033[1m"
Dim        = "\033[2m"
Underlined = "\033[4m"
Blink      = "\033[5m"
Reverse    = "\033[7m"
Hidden     = "\033[8m"

ResetBold       = "\033[21m"
ResetDim        = "\033[22m"
ResetUnderlined = "\033[24m"
ResetBlink      = "\033[25m"
ResetReverse    = "\033[27m"
ResetHidden     = "\033[28m"

Default      = "\033[39m"
Black        = "\033[30m"
Red          = "\033[31m"
Green        = "\033[32m"
Yellow       = "\033[33m"
Blue         = "\033[34m"
Magenta      = "\033[35m"
Cyan         = "\033[36m"
LightGray    = "\033[37m"
DarkGray     = "\033[90m"
LightRed     = "\033[91m"
LightGreen   = "\033[92m"
LightYellow  = "\033[93m"
LightBlue    = "\033[94m"
LightMagenta = "\033[95m"
LightCyan    = "\033[96m"
White        = "\033[97m"

Result:

Another better option is to not depend on PRINT or RAISERROR and just load your "print" statements into a ##Temp table in TempDB or a permanent table in your database which will give you visibility to the data immediately via a SELECT statement from another window. This works the best for me. Using a permanent table then also serves as a log to what happened in the past. The print statements are handy for errors, but using the log table you can also determine the exact point of failure based on the last logged value for that particular execution (assuming you track the overall execution start time in your log table.)

PrintStream out = System.out;
out.println( "hello" );

There's a section of @media print code in the css file (Bootstrap 3.3.1 [UPDATE:] to 3.3.5), this strips virtually all the styling, so you get fairly bland print-outs even when it is working.

For now I've had to resort to stripping out the @media print section from bootstrap.css - which I'm really not happy about but my users want direct screen-grabs so this'll have to do for now. If anyone knows how to suppress it without changes to the bootstrap files I'd be very interested.

Here's the 'offending' code block, starts at line #192:

@media print {
  *,
  *:before,enter code here

Check the following one-liner:

print('\n'.join("%s\n%s" % (key1,('\n'.join("%s : %r" % (key2,val2) for (key2,val2) in val1.items()))) for (key1,val1) in cars.items()))

Output:

A
speed : 70
color : 2
B
speed : 60
color : 3

My answer is intended for comment though but since i havent got enough reputation, i think it will still be relevant as an answer and help some one.

I find datatable in library DT robust to handle rownames, and columnames

Library DT
datatable(df, rownames = FALSE)  # no row names 

refer to https://rstudio.github.io/DT/ for usage scenarios

print("single",end=" ")
print("line")

this will give output

single line

for the question asked use

i = 0 
while i <10:
     i += 1 
     print (i,end="")

Assuming you use Python 2.7 (not 3):

print "I have", card.price (as mentioned above).

print "I have %s" % card.price (using string formatting)

print " ".join(map(str, ["I have", card.price])) (by joining lists)

There are a lot of ways to do the same, actually. I would prefer the second one.

"\n" this is the simple method to separate the continuous String

{glue} offers much better string interpolation, see my other answer. Also, as Dainis rightfully mentions, sprintf() is not without problems.

There's also sprintf():

sprintf("Current working dir: %s", wd)

To print to the console output, use cat() or message():

cat(sprintf("Current working dir: %s\n", wd))
message(sprintf("Current working dir: %s\n", wd))

for simple comments:

set serveroutput on format wrapped;
begin
    DBMS_OUTPUT.put_line('simple comment');
end;
/

-- do something

begin
    DBMS_OUTPUT.put_line('second simple comment');
end;
/

you should get:

anonymous block completed
simple comment

anonymous block completed
second simple comment

if you want to print out the results of variables, here's another example:

set serveroutput on format wrapped;
declare
a_comment VARCHAR2(200) :='first comment';
begin
    DBMS_OUTPUT.put_line(a_comment);
end;

/

-- do something


declare
a_comment VARCHAR2(200) :='comment';
begin
    DBMS_OUTPUT.put_line(a_comment || 2);
end;

your output should be:

anonymous block completed
first comment

anonymous block completed
comment2

Turgut gave the right solution. Just for clarity, you need to add close after writing.

function openWin()
  {
    myWindow=window.open('','','width=200,height=100');
    myWindow.document.write("<p>This is 'myWindow'</p>");


    myWindow.document.close(); //missing code


    myWindow.focus();
    myWindow.print(); 
  }

1. You will need to level order traverse your tree.
2. Choose node length and space length.
3. Get the tree's base width relative to each level which is node_length * nodes_count + space_length * spaces_count*.
4. Find a relation between branching, spacing, indentation and the calculated base width.

Paper CSS for happy printing

Front-end printing solution - previewable and live-reloadable!

Heres a solution with no Javascript or plugin - just some css and one extra class in the markup. This solutions uses the fact that BootStrap adds a class to the body when a dialog is open. We use this class to then hide the body, and print only the dialog.

To ensure we can determine the main body of the page we need to contain everything within the main page content in a div - I've used id="mainContent". Sample Page layout below - with a main page and two dialogs

<body>
 <div class="container body-content">

  <div id="mainContent">
       main page stuff     
  </div>
  <!-- Dialog One -->
  <div class="modal fade in">
   <div class="modal-dialog">
    <div class="modal-content">
          ...
    </div>
   </div>
  </div>

  <!-- Dialog Two -->
  <div class="modal fade in">
   <div class="modal-dialog">
    <div class="modal-content">
          ...
    </div>
   </div>
  </div>

 </div>
</body>

Then in our CSS print media queries, I use display: none to hide everything I don't want displayed - ie the mainContent when a dialog is open. I also use a specific class noPrint to be used on any parts of the page that should not be displayed - say action buttons. Here I am also hiding the headers and footers. You may need to tweak it to get exactly want you want.

@media print {
    header, .footer, footer {
        display: none;
    }

    /* hide main content when dialog open */
    body.modal-open div.container.body-content div#mainContent {
        display: none;
    }

    .noPrint {
        display: none;
    }
}

1. First ensure that printing is working from Report Manager (open a report in Report Manager and print from there).

2. If it works go to Step 3, if you received the same error you need to install the following patches on the Report Server.

How to flush output of Python print?

I suggest five ways of doing this:

• In Python 3, call print(..., flush=True) (the flush argument is not available in Python 2's print function, and there is no analogue for the print statement).
• Call file.flush() on the output file (we can wrap python 2's print function to do this), for example, sys.stdout
• apply this to every print function call in the module with a partial function,
  print = partial(print, flush=True) applied to the module global.
• apply this to the process with a flag (-u) passed to the interpreter command
• apply this to every python process in your environment with PYTHONUNBUFFERED=TRUE (and unset the variable to undo this).

Python 3.3+

Using Python 3.3 or higher, you can just provide flush=True as a keyword argument to the print function:

print('foo', flush=True) 

Python 2 (or < 3.3)

They did not backport the flush argument to Python 2.7 So if you're using Python 2 (or less than 3.3), and want code that's compatible with both 2 and 3, may I suggest the following compatibility code. (Note the __future__ import must be at/very "near the top of your module"):

from __future__ import print_function
import sys

if sys.version_info[:2] < (3, 3):
    old_print = print
    def print(*args, **kwargs):
        flush = kwargs.pop('flush', False)
        old_print(*args, **kwargs)
        if flush:
            file = kwargs.get('file', sys.stdout)
            # Why might file=None? IDK, but it works for print(i, file=None)
            file.flush() if file is not None else sys.stdout.flush()

The above compatibility code will cover most uses, but for a much more thorough treatment, see the six module.

Alternatively, you can just call file.flush() after printing, for example, with the print statement in Python 2:

import sys
print 'delayed output'
sys.stdout.flush()

Changing the default in one module to flush=True

You can change the default for the print function by using functools.partial on the global scope of a module:

import functools
print = functools.partial(print, flush=True)

if you look at our new partial function, at least in Python 3:

>>> print = functools.partial(print, flush=True)
>>> print
functools.partial(<built-in function print>, flush=True)

We can see it works just like normal:

>>> print('foo')
foo

And we can actually override the new default:

>>> print('foo', flush=False)
foo

Note again, this only changes the current global scope, because the print name on the current global scope will overshadow the builtin print function (or unreference the compatibility function, if using one in Python 2, in that current global scope).

If you want to do this inside a function instead of on a module's global scope, you should give it a different name, e.g.:

def foo():
    printf = functools.partial(print, flush=True)
    printf('print stuff like this')

If you declare it a global in a function, you're changing it on the module's global namespace, so you should just put it in the global namespace, unless that specific behavior is exactly what you want.

Changing the default for the process

I think the best option here is to use the -u flag to get unbuffered output.

$ python -u script.py

or

$ python -um package.module

From the docs:

Force stdin, stdout and stderr to be totally unbuffered. On systems where it matters, also put stdin, stdout and stderr in binary mode.

Note that there is internal buffering in file.readlines() and File Objects (for line in sys.stdin) which is not influenced by this option. To work around this, you will want to use file.readline() inside a while 1: loop.

Changing the default for the shell operating environment

You can get this behavior for all python processes in the environment or environments that inherit from the environment if you set the environment variable to a nonempty string:

e.g., in Linux or OSX:

$ export PYTHONUNBUFFERED=TRUE

or Windows:

C:\SET PYTHONUNBUFFERED=TRUE

from the docs:

PYTHONUNBUFFERED

If this is set to a non-empty string it is equivalent to specifying the -u option.

Addendum

Here's the help on the print function from Python 2.7.12 - note that there is no flush argument:

>>> from __future__ import print_function
>>> help(print)
print(...)
    print(value, ..., sep=' ', end='\n', file=sys.stdout)
    
    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file: a file-like object (stream); defaults to the current sys.stdout.
    sep:  string inserted between values, default a space.
    end:  string appended after the last value, default a newline.

EDIT In hind-sight, I think the potential confusion with changing sys.stderr and not seeing the behaviour updated makes this answer not as good as just using a simple function as others have pointed out.

Using partial only saves you 1 line of code. The potential confusion is not worth saving 1 line of code.

original

To make it even easier, here's a version that uses 'partial', which is a big help in wrapping functions.

from __future__ import print_function
import sys
from functools import partial

error = partial(print, file=sys.stderr)

You then use it like so

error('An error occured!')

You can check that it's printing to stderr and not stdout by doing the following (over-riding code from http://coreygoldberg.blogspot.com.au/2009/05/python-redirect-or-turn-off-stdout-and.html):

# over-ride stderr to prove that this function works.
class NullDevice():
    def write(self, s):
        pass
sys.stderr = NullDevice()

# we must import print error AFTER we've removed the null device because
# it has been assigned and will not be re-evaluated.
# assume error function is in print_error.py
from print_error import error

# no message should be printed
error("You won't see this error!")

The downside to this is partial assigns the value of sys.stderr to the wrapped function at the time of creation. Which means, if you redirect stderr later it won't affect this function. If you plan to redirect stderr, then use the **kwargs method mentioned by aaguirre on this page.

You can try with GhostScript like in this post:

How to print PDF on default network printer using GhostScript (gswin32c.exe) shell command

I doubt there is one... It depends on browser, on printer (physical max dpi) and its driver, on paper size as you point out (and I might want to print on B5 paper too...), on settings (landscape or portrait?), plus you often can change the scale (percentage), etc.
Let the users tweak their settings...

Most of the libraries commonly used in C++ can't print arrays, per se. You'll have to loop through it manually and print out each value.

Printing arrays and dumping many different kinds of objects is a feature of higher level languages.

OK, finally I found a good solution for my bill printing task and it is working properly for me.

This class provides the print service

public class PrinterService {

    public PrintService getCheckPrintService(String printerName) {
        PrintService ps = null;
        DocFlavor doc_flavor = DocFlavor.STRING.TEXT_PLAIN;
        PrintRequestAttributeSet attr_set =
                new HashPrintRequestAttributeSet();

        attr_set.add(new Copies(1));           
        attr_set.add(Sides.ONE_SIDED);
        PrintService[] service = PrintServiceLookup.lookupPrintServices(doc_flavor, attr_set);

        for (int i = 0; i < service.length; i++) {
            System.out.println(service[i].getName());
            if (service[i].getName().equals(printerName)) {
                ps = service[i];
            }
        }
        return ps;
    }
}

This class demonstrates the bill printing task,

public class HelloWorldPrinter implements Printable {

    @Override
    public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
        if (pageIndex > 0) { /* We have only one page, and 'page' is zero-based */
            return NO_SUCH_PAGE;
        }

        Graphics2D g2d = (Graphics2D) graphics;
        g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());

        //the String to print in multiple lines
        //writing a semicolon (;) at the end of each sentence
        String mText = "SHOP MA;"
                + "Pannampitiya;"
                + "----------------------------;"
                + "09-10-2012 harsha  no: 001 ;"
                + "No  Item  Qty  Price  Amount ;"
                + "----------------------------;"
                + "1 Bread 1 50.00  50.00 ;"
                + "----------------------------;";

        //Prepare the rendering
        //split the String by the semicolon character
        String[] bill = mText.split(";");
        int y = 15;
        Font f = new Font(Font.SANS_SERIF, Font.PLAIN, 8);
        graphics.setFont(f);
        //draw each String in a separate line
        for (int i = 0; i < bill.length; i++) {
            graphics.drawString(bill[i], 5, y);
            y = y + 15;
        }

        /* tell the caller that this page is part of the printed document */
        return PAGE_EXISTS;
    }

    public void pp() throws PrinterException {
        PrinterService ps = new PrinterService();
        //get the printer service by printer name
        PrintService pss = ps.getCheckPrintService("Deskjet-1000-J110-series-2");

        PrinterJob job = PrinterJob.getPrinterJob();
        job.setPrintService(pss);
        job.setPrintable(this);

        try {
            job.print();
        } catch (PrinterException ex) {
            ex.printStackTrace();
        }

    }

    public static void main(String[] args) {
        HelloWorldPrinter hwp = new HelloWorldPrinter();
        try {
            hwp.pp();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Regain control of your console! Simply:

from __past__ import printf

where __past__.py contains:

import sys
def printf(fmt, *varargs):
    sys.stdout.write(fmt % varargs)

then:

>>> printf("Hello, world!\n")
Hello, world!
>>> printf("%d %d %d\n", 0, 1, 42)
0 1 42
>>> printf('a'); printf('b'); printf('c'); printf('\n')
abc
>>>

Bonus extra: If you don't like print >> f, ..., you can extending this caper to fprintf(f, ...).

As you are using a print function with a selector which is a part of print.js so you need to call them before you use it...

Else 
    window.print()  

will do it

$("#btn").click(function () {
    $("#printarea").print();
});

or

$("#btn").on('click',function () {
    $("#printarea").print();
});

It's entirely possible to set your layout to assume the proportions of an a4 page. You would only have to set width and height accordingly (possibly check with window.innerHeight and window.innerWidth although I'm not sure if that is reliable).

The tricky part is with printing A4. Javascript for example only supports printing pages rudimentarily with the window.print method. As @Prutswonder suggested creating a PDF from the webpage probably is the most sophisticated way of doing this (other than supplying PDF documentation in the first place). However, this is not as trivial as one might think. Here's a link that has a description of an all open source Java class to create PDFs from HTML: http://www.javaworld.com/javaworld/jw-04-2006/jw-0410-html.html .

Obviously once you have created a PDF with A4 proportions printing it will result in a clean A4 print of your page. Whether that's worth the time investment is another question.

I done this way:

$scope.printDiv = function (div) {
  var docHead = document.head.outerHTML;
  var printContents = document.getElementById(div).outerHTML;
  var winAttr = "location=yes, statusbar=no, menubar=no, titlebar=no, toolbar=no,dependent=no, width=865, height=600, resizable=yes, screenX=200, screenY=200, personalbar=no, scrollbars=yes";

  var newWin = window.open("", "_blank", winAttr);
  var writeDoc = newWin.document;
  writeDoc.open();
  writeDoc.write('<!doctype html><html>' + docHead + '<body onLoad="window.print()">' + printContents + '</body></html>');
  writeDoc.close();
  newWin.focus();
}

<body onload="window.print()"> or window.onload = function() { window.print(); }

you cannot set this in javascript, you have to do this with html/css:

<style type="text/css" media="print">
  @page { size: landscape; }
</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

Just wanted to put an update. page-break-after is a legacy property now.

Official page states

This property has been replaced by the break-after property.

You can use prettytable to render the table as text. The trick is to convert the data_frame to an in-memory csv file and have prettytable read it. Here's the code:

from StringIO import StringIO
import prettytable    

output = StringIO()
data_frame.to_csv(output)
output.seek(0)
pt = prettytable.from_csv(output)
print pt

The below code works well for me (at least for Chrome).

I also added some margin and page orientation controls.(portrait, landscape)

<style type="text/css" media="print">
@media print {
  body {-webkit-print-color-adjust: exact;}
}
@page {
    size:A4 landscape;
    margin-left: 0px;
    margin-right: 0px;
    margin-top: 0px;
    margin-bottom: 0px;
    margin: 0;
    -webkit-print-color-adjust: exact;
}
</style>

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

See here for more information:

• Special Method Names - Basic Customization

if you really need System.out.println to work(eg. it's called from third party library). you can simply use reflection to change out field in System.class:

try{
    Field outField = System.class.getDeclaredField("out");
    Field modifiersField = Field.class.getDeclaredField("accessFlags");
    modifiersField.setAccessible(true);
    modifiersField.set(outField, outField.getModifiers() & ~Modifier.FINAL);
    outField.setAccessible(true);
    outField.set(null, new PrintStream(new RedirectLogOutputStream()); 
}catch(NoSuchFieldException e){
    e.printStackTrace(); 
}catch(IllegalAccessException e){
    e.printStackTrace(); 
}

RedirectLogOutputStream class:

public class RedirectLogOutputStream extends OutputStream{
    private String mCache;

    @Override
    public void write(int b) throws IOException{
        if(mCache == null) mCache = "";

        if(((char) b) == '\n'){
            Log.i("redirect from system.out", mCache);
            mCache = "";
        }else{
            mCache += (char) b;
        }
    }
}

I usually do something similar to the approach given by How to Use JavaScript to Print a PDF (eHow.com), using an iframe.

1. a function to house the print trigger...

   function printTrigger(elementId) {
       var getMyFrame = document.getElementById(elementId);
       getMyFrame.focus();
       getMyFrame.contentWindow.print();
   }
   

2. an button to give the user access...

   (an onClick on an a or button or input or whatever you wish)

   <input type="button" value="Print" onclick="printTrigger('iFramePdf');" />
   

3. an iframe pointing to your PDF...

   <iframe id="iFramePdf" src="myPdfUrl.pdf" style="display:none;"></iframe>
   

Bonus Idea #1 - Create the iframe and add it to your page within the printTrigger(); so that the PDF isn't loaded until the user clicks your "Print" button, then the javascript can attack! the iframe and trigger the print dialog.

Bonus Idea #2 - Extra credit if you disable your "Print" button and give the user a little loading spinner or something after they click it, so that they know something's in process instead of clicking it repeatedly!

Try the format syntax:

print ("{0}. {1} appears {2} times.".format(1, 'b', 3.1415))

Outputs:

1. b appears 3.1415 times.

The print function is called just like any other function, with parenthesis around all its arguments.

No behaviors can be set by CSS. The only way to disable something in CSS is to make it invisible by either setting display:none or simply putting div with transparent img all over it and changing their z-orders to disable user focusing on it with mouse. Even though, user will still be able to focus with tab from another field.

You can either use the f-string or .format() methods

Using f-string

print(f'If there was a birth every 7 seconds, there would be: {births} births')

Using .format()

print("If there was a birth every 7 seconds, there would be: {births} births".format(births=births))

You could place the link within a div, then use JavaScript on the anchor tag to hide the div when clicked. Example (not tested, may need to be tweaked but you get the idea):

<div id="printOption">
    <a href="javascript:void();" 
       onclick="document.getElementById('printOption').style.visibility = 'hidden'; 
       document.print(); 
       return true;">
       Print
    </a>
</div>

The downside is that once clicked, the button disappears and they lose that option on the page (there's always Ctrl+P though).

The better solution would be to create a print stylesheet and within that stylesheet specify the hidden status of the printOption ID (or whatever you call it). You can do this in the head section of the HTML and specify a second stylesheet with a media attribute.

I just needed to add the !important attribute onto the the background-color tag in order for it to show up, did not need the webkit part:

background-color: #f5f5f5 !important;

If you want to concatenate int or floats to a string you must use this:

i = 123
a = "foobar"
s = a + str(i)

You can simply give it as:

System.out.println("Address:" +houseAddress);

Your output will look like [address1, address2, address3]

This is because the class ArrayList or its superclass would have a toString() function overridden.

Hope this helps.

There's at least one situation in which you want sys.stdout instead of print.

When you want to overwrite a line without going to the next line, for instance while drawing a progress bar or a status message, you need to loop over something like

Note carriage return-> "\rMy Status Message: %s" % progress

And since print adds a newline, you are better off using sys.stdout.

This does almost everything you want:

f = open('data.txt', 'rb')

while True:
    char = f.read(1)
    if not char: break
    print "{:02x}".format(ord(char)),

With data.txt created like this:

f = open('data.txt', 'wb')
f.write("ab\r\ncd")
f.close()

I get the following output:

61 62 0d 0a 63 64

tl;dr -- 1. You are using poor variable names. 2. You are slicing your hex strings incorrectly. 3. Your code is never going to replace any newlines. You may just want to forget about that feature. You do not quite yet understand the difference between a character, its integer code, and the hex string that represents the integer. They are all different: two are strings and one is an integer, and none of them are equal to each other. 4. For some files, you shouldn't remove newlines.

===

1. Your variable names are horrendous.

That's fine if you never want to ask anybody questions. But since every one needs to ask questions, you need to use descriptive variable names that anyone can understand. Your variable names are only slightly better than these:

fname = 'data.txt'
f = open(fname, 'rb')
xxxyxx = f.read()

xxyxxx = len(xxxyxx)
print "Length of file is", xxyxxx, "bytes. "
yxxxxx = 0

while yxxxxx < xxyxxx:
    xyxxxx = hex(ord(xxxyxx[yxxxxx]))
    xyxxxx = xyxxxx[-2:]
    yxxxxx = yxxxxx + 1
    xxxxxy = chr(13) + chr(10)
    xxxxyx = str(xxxxxy)
    xyxxxxx = str(xyxxxx)
    xyxxxxx.replace(xxxxyx, ' ')
    print xyxxxxx

That program runs fine, but it is impossible to understand.

2. The hex() function produces strings of different lengths.

For instance,

print hex(61)
print hex(15)

--output:--
0x3d
0xf

And taking the slice [-2:] for each of those strings gives you:

3d
xf

See how you got the 'x' in the second one? The slice:

[-2:] 

says to go to the end of the string and back up two characters, then grab the rest of the string. Instead of doing that, take the slice starting 3 characters in from the beginning:

[2:]  

3. Your code will never replace any newlines.

Suppose your file has these two consecutive characters:

"\r\n"

Now you read in the first character, "\r", and convert it to an integer, ord("\r"), giving you the integer 13. Now you convert that to a string, hex(13), which gives you the string "0xd", and you slice off the first two characters giving you:

"d"

Next, this line in your code:

bndtx.replace(entx, ' ')

tries to find every occurrence of the string "\r\n" in the string "d" and replace it. There is never going to be any replacement because the replacement string is two characters long and the string "d" is one character long.

The replacement won't work for "\r\n" and "0d" either. But at least now there is a possibility it could work because both strings have two characters. Let's reduce both strings to a common denominator: ascii codes. The ascii code for "\r" is 13, and the ascii code for "\n" is 10. Now what about the string "0d"? The ascii code for the character "0" is 48, and the ascii code for the character "d" is 100. Those strings do not have a single character in common. Even this doesn't work:

 x = '0d' + '0a'
 x.replace("\r\n", " ")
 print x

 --output:--
 '0d0a'

Nor will this:

x = 'd' + 'a'
x.replace("\r\n", " ")
print x

--output:--
da

The bottom line is: converting a character to an integer then to a hex string does not end up giving you the original character--they are just different strings. So if you do this:

char = "a"
code = ord(char)
hex_str = hex(code)

print char.replace(hex_str, " ")

...you can't expect "a" to be replaced by a space. If you examine the output here:

char = "a"
print repr(char)

code = ord(char)
print repr(code)

hex_str = hex(code)
print repr(hex_str)

print repr(
    char.replace(hex_str, " ")
)

--output:--
'a'
97
'0x61'
'a'

You can see that 'a' is a string with one character in it, and '0x61' is a string with 4 characters in it: '0', 'x', '6', and '1', and you can never find a four character string inside a one character string.

4) Removing newlines can corrupt the data.

For some files, you do not want to replace newlines. For instance, if you were reading in a .jpg file, which is a file that contains a bunch of integers representing colors in an image, and some colors in the image happened to be represented by the number 13 followed by the number 10, your code would eliminate those colors from the output.

However, if you are writing a program to read only text files, then replacing newlines is fine. But then, different operating systems use different newlines. You are trying to replace Windows newlines(\r\n), which means your program won't work on files created by a Mac or Linux computer, which use \n for newlines. There are easy ways to solve that, but maybe you don't want to worry about that just yet.

I hope all that's not too confusing.

For Python 2.*:

If you overload the function __str__() for your Person class, you can omit the part with map(str, ...). Another way for this is creating a function, just like you wrote:

def write_list(lst):
    for item in lst:
        print str(item) 

...

write_list(MyList)

There is in Python 3.* the argument sep for the print() function. Take a look at documentation.

I have looked around for a fix for this. I have a jquery mobile site that has a final print page and it combines dozens of pages. I tried all the fixes above but the only thing I could get to work is this:

<div style="clear:both!important;"/></div>
<div style="page-break-after:always"></div> 
<div style="clear:both!important;"/> </div>

If you want them to show up one at a time, you can do this:

import time
import sys
for i in range(20):
    sys.stdout.write('a')
    sys.stdout.flush()
    time.sleep(0.5)

sys.stdout.flush() is necessary to force the character to be written each time the loop is run.

I encountered a similar problem only with a nested img in my anchor:

<a href="some/link">
   <img src="some/src">
</a>

When I applied

@media print {
   a[href]:after {
      content: none !important;
   }
}

I lost my img and the entire anchor width for some reason, so instead I used:

@media print {
   a[href]:after {
      visibility: hidden;
   }
}

which worked perfectly.

Bonus tip: inspect print preview

You shouldn't need to let the users specify the margin on your website - Let them do it on their computer. Print dialogs usually (Adobe and Preview, at least) give you an option to scale and center the output on the printable area of the page:

Adobe

Preview

Of course, this assumes that you have computer literate users, which may or may not be the case.

base on @Kevin Florida answer, i made a way to avoid script on current page disable because of overwrite content. I use other file called "printScreen.php" (or .html). Wrap everything you want to print in a div "printSource". And with javascript, open a new window you created before ("printScreen.php") then grab content in "printSource" of top window.

Here is the code.

Main window :

echo "<div id='printSource'>";
//everything you want to print here
echo "</div>";

//add button or link to print
echo "<button id='btnPrint'>Print</button>";

<script>
  $("#btnPrint").click(function(){
    printDiv("printSource");
  });

  function printDiv(divName) {
   var printContents = document.getElementById(divName).innerHTML;
   var originalContents = document.body.innerHTML;
   w=window.open("printScreen.php", "_blank", "toolbar=yes,scrollbars=yes,resizable=yes,top=50,left=50,width=900,height=400");
   }
</script>

This is "printScreen.php" - other file to grab content to print

<head>
// write everything about style/script here (.css, .js)

</head>
<body id='mainBody'></body>
</html>


<script>
    //get everything you want to print from top window
    src = window.opener.document.getElementById("printSource").innerHTML;

    //paste to "mainBody"
    $("#mainBody").html(src);
    window.print();
    window.close();
</script>

The three constants have similar functions nowadays, but different historical origins, and very occasionally you may be required to use one or the other.

You need to think back to the days of old manual typewriters to get the origins of this. There are two distinct actions needed to start a new line of text:

1. move the typing head back to the left. In practice in a typewriter this is done by moving the roll which carries the paper (the "carriage") all the way back to the right -- the typing head is fixed. This is a carriage return.
2. move the paper up by the width of one line. This is a line feed.

In computers, these two actions are represented by two different characters - carriage return is CR, ASCII character 13, vbCr; line feed is LF, ASCII character 10, vbLf. In the old days of teletypes and line printers, the printer needed to be sent these two characters -- traditionally in the sequence CRLF -- to start a new line, and so the CRLF combination -- vbCrLf -- became a traditional line ending sequence, in some computing environments.

The problem was, of course, that it made just as much sense to only use one character to mark the line ending, and have the terminal or printer perform both the carriage return and line feed actions automatically. And so before you knew it, we had 3 different valid line endings: LF alone (used in Unix and Macintoshes), CR alone (apparently used in older Mac OSes) and the CRLF combination (used in DOS, and hence in Windows). This in turn led to the complications of DOS / Windows programs having the option of opening files in text mode, where any CRLF pair read from the file was converted to a single CR (and vice versa when writing).

So - to cut a (much too) long story short - there are historical reasons for the existence of the three separate line separators, which are now often irrelevant: and perhaps the best course of action in .NET is to use Environment.NewLine which means someone else has decided for you which to use, and future portability issues should be reduced.

I think the best that's possible in cross-browser JavaScript is window.print(), which (in Firefox 3, for me) brings up the 'print' dialog and not the print preview dialog.

FYI, the print dialog is your computer's Print popup, what you get when you do Ctrl-p. The print preview is Firefox's own Preview window, and it has more options. It's what you get with Firefox Menu > Print...

Today I was looking for this very solution and I tried PDFtoPrinter which I had an issue with (the PDFs I tried printing suggested they used incorrect paper size which hung the print job and nothing else printed until resolved). In my effort to find an alternative, I remembered GhostScript and utilities associated with it. I found GSView and it's associated program GSPrint (reference https://www.ghostscript.com/). Both these require GhostScript (https://www.ghostscript.com/) but when all the components are installed, GSPrint worked flawlessly and I was able to create a scheduled task that printed PDFs automatically overnight.

This simple example will print 1-10 on the same line.

for i in range(1,11):
    print (i, end=" ")

It provides human readable version of output rather "Object": Example:

class Pet(object):

    def __init__(self, name, species):
        self.name = name
        self.species = species

    def getName(self):
        return self.name

    def getSpecies(self):
        return self.species

    def Norm(self):
        return "%s is a %s" % (self.name, self.species)

if __name__=='__main__':
    a = Pet("jax", "human")
    print a 

returns

<__main__.Pet object at 0x029E2F90>

while code with "str" return something different

class Pet(object):

    def __init__(self, name, species):
        self.name = name
        self.species = species

    def getName(self):
        return self.name

    def getSpecies(self):
        return self.species

    def __str__(self):
        return "%s is a %s" % (self.name, self.species)

if __name__=='__main__':
    a = Pet("jax", "human")
    print a 

returns:

jax is a human

change

print item

to

print "\033[K", item, "\r",
sys.stdout.flush()

• "\033[K" clears to the end of the line
• the \r, returns to the beginning of the line
• the flush statement makes sure it shows up immediately so you get real-time output.

The problem is that skew isn't being subsetted in colour=factor(skew), so it's the wrong length. Since subset(skew, product == 'p1') is the same as subset(skew, product == 'p3'), in this case it doesn't matter which subset is used. So you can solve your problem with:

p1 <- ggplot(df, aes(x=subset(price, product=='p1'),
                     y=subset(price, product=='p3'),
                     colour=factor(subset(skew, product == 'p1')))) +
              geom_point(size=2, shape=19)

Note that most R users would write this as the more concise:

p1 <- ggplot(df, aes(x=price[product=='p1'],
                     y=price[product=='p3'],
                     colour=factor(skew[product == 'p1']))) +
              geom_point(size=2, shape=19)

check the solution provided here it may help, i use it in my projects. http://trentrichardson.com/examples/timepicker/ .(in the end of the page)

FULL is probably referring to a full table scan, which means that no indexes are in use. This is usually indicating that something is wrong, unless the query is supposed to use all the rows in a table.

Cost is a number that signals the sum of the different loads, processor, memory, disk, IO, and high numbers are typically bad. The numbers are added up when moving to the root of the plan, and each branch should be examined to locate the bottlenecks.

You may also want to query v$sql and v$session to get statistics about SQL statements, and this will have detailed metrics for all kind of resources, timings and executions.

For me, this error came up when I was trying to rollback a transaction block after encountering an exception, inside another transaction block.

All I had to do to fix it was to remove my inner transaction block.

Things can get quite messy when using nested transactions, best to avoid this and just restructure your code.

I believe in order to have auto-wiring work on your MyLauncher class (for myService), you will need to let Spring initialize it instead of calling the constructor, by auto-wiring myLauncher. Once that is being auto-wired (and myService is also getting auto-wired), Spring (1.4.0 and up) provides a @MockBean annotation you can put in your test. This will replace a matching single beans in context with a mock of that type. You can then further define what mocking you want, in a @Before method.

public class MyLauncherTest
    @MockBean
    private MyService myService;

    @Autowired
    private MyLauncher myLauncher;

    @Before
    private void setupMockBean() {
        doNothing().when(myService).someVoidMethod();
        doReturn("Some Value").when(myService).someStringMethod();
    }

    @Test
    public void someTest() {
        myLauncher.doSomething();
    }
}

Your MyLauncher class can then remain unmodified, and your MyService bean will be a mock whose methods return values as you defined:

@Component
public class MyLauncher {
    @Autowired
    MyService myService;

    public void doSomething() {
        myService.someVoidMethod();
        myService.someMethodThatCallsSomeStringMethod();
    }

    //other methods
}

A couple advantages of this over other methods mentioned is that:

1. You don't need to manually inject myService.
2. You don't need use the Mockito runner or rules.

Why not try fadeOut?

$(document).ready(function() {_x000D_
  $('#plsme').fadeOut(5000); // 5 seconds x 1000 milisec = 5000 milisec_x000D_
});

/^[a-z]{0,10}$/ should work. /^[a-z]{1,10}$/ if you want to match at least one character, like /^[a-z]+$/ does.

No, an iPhone application can only change stuff within its own little sandbox. (And even there there are things that you can't change on the fly.)

Your best bet is probably to use the servers IP address rather than hostname. Slightly harder, but not that hard if you just need to resolve a single address, would be to put a DNS server on your Mac and configure your iPhone to use that.

Inside of your loop, you have the key, which you can use to retrieve the value from the Map:

for (String key: mss1.keySet()) {
    System.out.println(key + ": " + mss1.get(key));
}

You can call sortable on a <tbody> instead of on the individual rows.

    <tbody>
        <tr> 
            <td>1</td>
            <td>2</td>

Theoretically, you can compare edit distances.

You're missing a GROUP BY clause:

SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.

To change a cell value using a column name, one can use

iris$Sepal.Length[3]=999

This problem also arise when we don't give the single or double quotes to the database value.

Wrong way:

$query ="INSERT INTO tabel_name VALUE ($value1,$value2)";

As database inserting values must be in quotes ' '/" "

Right way:

$query ="INSERT INTO STUDENT VALUE ('$roll_no','$name','$class')";

you can convert this string into an array of chars using split(), then iterate through it.

const str = "javascript";_x000D_
const strArray = str.split('');_x000D_
_x000D_
strArray.map(s => console.log(s));

If you installed it with homebrew, the binary will be somewhere like

/usr/local/Cellar/mysql/5.6.10/bin/mysqld

which means you can start it with

/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server start

and stop it with

/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server stop

Edit: As Jacob Raccuia mentioned, make sure you put the appropriate version of MySQL in the path.

Use this manual http://blog.antoine.li/2010/10/22/android-trusting-ssl-certificates/ This guide really helped me. It is important to observe a sequence of certificates in the store. For example: import the lowermost Intermediate CA certificate first and then all the way up to the Root CA certificate.

I see that this post is old. But in version CI v3 here is the answer:

echo $this->uri->uri_string();

As of Oct 2019, SQL Server Management Studio, they did not upgraded the SSMS to add create ER Diagram feature.

I would suggest try using DBWeaver from here :

https://dbeaver.io/download/

I am using Mac and Windows both and I was able to download the community edition and logged into my SQL server database and was able to create the ER diagram using the DB Weaver.

You can do it by setting an int and masking off bits, but probably the easiest way is just to use the built in network byte conversion ops (since network byte order is always big endian).

if ( htonl(47) == 47 ) {
  // Big endian
} else {
  // Little endian.
}

Bit fiddling could be faster, but this way is simple, straightforward and pretty impossible to mess up.

Adding a system variable JDK_HOME with value c:\Program Files\Java\jdk1.7.0_21\ worked for me. The latest Java release can be downloaded here.

Additionally, make sure the variable JAVA_HOME is also set with the above location.

Compilr is an online java compiler. It provides syntax highlighting and reports any errors back to you. It's a project I'm working on, so if you have any feedback please leave a comment!

For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.

See here for an example.

I've used this function to merge objects in the past, I use it to add or update existing properties on obj1 with values from obj2:

var _mergeRecursive = function(obj1, obj2) {

      //iterate over all the properties in the object which is being consumed
      for (var p in obj2) {
          // Property in destination object set; update its value.
          if ( obj2.hasOwnProperty(p) && typeof obj1[p] !== "undefined" ) {
            _mergeRecursive(obj1[p], obj2[p]);

          } else {
            //We don't have that level in the heirarchy so add it
            obj1[p] = obj2[p];

          }
     }
}

It will handle multiple levels of hierarchy as well as single level objects. I used it as part of a utility library for manipulating JSON objects. You can find it here.

I suspect most everyone really wants to disable zoom/scroll in order to put together a more app-like experience; because the answers seem to contain elements of solutions for both zooming and scrolling, but nobody's really nailed either one down.

Scrolling

To answer OP, the only thing you seem to need to do to disable scrolling is intercept the window's scroll and touchmove events and call preventDefault and stopPropagation on the events they generate; like so

window.addEventListener("scroll", preventMotion, false);
window.addEventListener("touchmove", preventMotion, false);

function preventMotion(event)
{
    window.scrollTo(0, 0);
    event.preventDefault();
    event.stopPropagation();
}

And in your stylesheet, make sure your body and html tags include the following:

html:
{
    overflow: hidden;
}

body
{
    overflow: hidden;
    position: relative;
    margin: 0;
    padding: 0;
}

Zooming

However, scrolling is one thing, but you probably want to disable zoom as well. Which you do with the meta tag in your markup:

<meta name="viewport" content="user-scalable=no" />

All of these put together give you an app-like experience, probably a best fit for canvas.

(Be wary of the advice of some to add attributes like initial-scale and width to the meta tag if you're using a canvas, because canvasses scale their contents, unlike block elements, and you'll wind up with an ugly canvas, more often than not).

site-packages is just the location where Python installs its modules.

No need to "find it", python knows where to find it by itself, this location is always part of the PYTHONPATH (sys.path).

Programmatically you can find it this way:

import sys
site_packages = next(p for p in sys.path if 'site-packages' in p)
print site_packages

'/Users/foo/.envs/env1/lib/python2.7/site-packages'

lowercase-with-hyphens is the style I most often see on GitHub.*

lowercase_with_underscores is probably the second most popular style I see.

The former is my preference because it saves keystrokes.

Try smallR for writing quick R scripts in the command line:

http://code.google.com/p/simple-r/

(r command in the directory)

Plotting from the command line using smallR would look like this:

r -p file.txt

Go to run as and choose Run Configurations -> Common and in the Standard Input and Output you can choose a File also.

Here is an awk based on oogas sed

echo 'abbc' | awk '{gsub(/ab/,"xy");gsub(/bc/,"ab");gsub(/xy/,"bc")}1'
bcab

For those looking for a C# workaround:

If you need for some reason to have the "AutoGeneratedColumns" enabled, one thing you can do is to specify all the columns's width except the ones you want to be auto resized (it will not take the remaining space, but it will resize to the cell's content).

Example (dgShopppingCart is my DataGrid):

dgShoppingCart.Columns[0].Visibility = Visibility.Hidden; 
dgShoppingCart.Columns[1].Header = "Qty";
dgShoppingCart.Columns[1].Width = 100;
dgShoppingCart.Columns[2].Header = "Product Name"; /*This will be resized to cell content*/
dgShoppingCart.Columns[3].Header = "Price";
dgShoppingCart.Columns[3].Width = 100;
dgShoppingCart.Columns[4].Visibility = Visibility.Hidden; 

For me it works as a workaround because I needed to have the DataGrid resized when the user maximize the Window.

timespec_get from C11 returns up to nanoseconds, rounded to the resolution of the implementation.

#include <time.h>
struct timespec ts;
timespec_get(&ts, TIME_UTC);
struct timespec {
    time_t   tv_sec;        /* seconds */
    long     tv_nsec;       /* nanoseconds */
};

This is my AppTheme on an example app:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowIsTranslucent">true</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

As you can see, I have the default colors and then I added the android:windowIsTranslucent and set it to true.

As far as I know as an Android Developer, this is the only thing you need to set in order to hide the white screen on the start of the application.

For the replacement string and the replacement pattern as specified by $. here a resume:

link to doc : here

"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")

Note:

If you want to have a $ in the replacement string use $$. Same as with vscode snippet system.

Not a direct answer to OP's problem, but it may help you too. You can declare a local variable next to some html inside a scope without trouble.

@foreach (var item in Model.Stuff)
{
    var file = item.MoreStuff.FirstOrDefault();

    <li><a href="@item.Source">@file.Name</a></li>
}

import platform
is_windows = any(platform.win32_ver())

or

import sys
is_windows = hasattr(sys, 'getwindowsversion')

There would be another way to do this:

var begin = moment().format("YYYY-MM-01");
var end = moment().format("YYYY-MM-") + moment().daysInMonth();

This will do it System.IO.Compression.ZipFile.ExtractToDirectory(ZipName, ExtractToPath)

Workaround simple and quick. Upload file/photo on cloud (from outside the emulator) and download with browser on the emulator.

Pipe it to awk:

awk '{if(NR>1)print}'

or sed

sed -n '1!p'

Is this worth mentioning?

var item = new Stack(arr).Pop();

Add an additional CSS class that blocks the transition, and then remove it to return to the previous state. This make both CSS and JQuery code short, simple and well understandable.

CSS:

.notransition {
  -webkit-transition: none !important;
  -moz-transition: none !important;
  -o-transition: none !important;
  -ms-transition: none !important;
  transition: none !important;
}

!important was added to be sure that this rule will have more "weight", because ID is normally more specific than class.

JQuery:

$('#elem').addClass('notransition'); // to remove transition
$('#elem').removeClass('notransition'); // to return to previouse transition

I know this is old questions but since I too have the same problem just now and found out the answer, thought I might share it. The problem was due to configuration at pood.d/ directory.

Restart both nginx and php5-fpm service afterwards and check if php5-fpm.sock already created.

I've just had this issue, however it didn't occur straight away; after selecting a few cells they would stop calling didSelectItemAtIndexPath. I realised that the problem was the collection view had allowsMultipleSelection set to TRUE. Because cells were never getting deselected this stopped future calls from calling didSelectItemAtIndexPath.

You are getting NullReferenceExeption because of you are using the cmb.SelectedValue which is null. the comboBox doesn't know what is the value of your custom class ComboboxItem, so either do:

ComboboxItem selectedCar = (ComboboxItem)comboBox2.SelectedItem;
int selecteVal = Convert.ToInt32(selectedCar.Value);

Or better of is use data binding like:

ComboboxItem item1 = new ComboboxItem();
item1.Text = "test";
item1.Value = "123";

ComboboxItem item2 = new ComboboxItem();
item2.Text = "test2";
item2.Value = "456";

List<ComboboxItem> items = new List<ComboboxItem> { item1, item2 };

this.comboBox1.DisplayMember = "Text";
this.comboBox1.ValueMember = "Value";
this.comboBox1.DataSource = items;

        }
    }
}

You need to create a query (in Visual Studio, right-click on the DB connection -> New Query) and execute the following SQL:

ALTER TABLE tblAlpha
ADD CONSTRAINT MyConstraint FOREIGN KEY (FK_id) REFERENCES
tblGamma(GammaID)
ON UPDATE CASCADE

To verify that your foreign key was created, execute the following SQL:

SELECT * FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS

Most of the solutions consider that the lists do not have duplicates. In case your lists do have duplicates you can try this:

def isSubList(subList,mlist):
    uniqueElements=set(subList)
    for e in uniqueElements:
        if subList.count(e) > mlist.count(e):
            return False     
    # It is sublist
    return True

It ensures the sublist never has different elements than list or a greater amount of a common element.

lst=[1,2,2,3,4]
sl1=[2,2,3]
sl2=[2,2,2]
sl3=[2,5]

print(isSubList(sl1,lst)) # True
print(isSubList(sl2,lst)) # False
print(isSubList(sl3,lst)) # False

For people who want to use multiple images of course importing them one by one would be a problem. The solution is to move the images folder to the public folder. So if you had an image at public/images/logo.jpg, you could display that image this way:

function Header() {
  return (
    <div>
      <img src="images/logo.jpg" alt="logo"/>
    </div>
  );
}

Yes, no need to use /public/ in the source.

I still experience occasional black screens with latest Chrome 60 with GPU acceleration enabled by default (probably caused by lack of free memory for numerous tabs).

Sometimes it helps to kill GPU process in builtin Task manager (Shift+Esc) as @amit suggests. But sometimes this forces more Chrome windows to become black while some others may remain normal.

I've noticed that tabs headers and address bar of black windows remain funtional and tabs can be fully repaired just by dragging them out of black windows. But it's too tedious to do this one by one when their number is huge.

So here is quick completely restartless solution inspired by Merging windows of Google Chrome:

• Add a new empty tab to black window (Ctrl+T)
• Left-click the first tab in the window
• Then hold the Shift key and left-click the right most tab just before the empty one
• Drag all the selected tabs at once out of the black window
• Close the black window with remaining single empty tab

what you're looking for is SUBSTITUTE:

=SUBSTITUTE(A2,"Author","Authoring")

Will substitute Author for Authoring without messing with everything else

Object destructuring the parameter object is what many of the answers above are aiming for and Typescript now has the methods in place to make it much easier to read and intuitively understand.

Destructuring Basics: By destructuring an object, you can choose properties from an object by key name. You can define as few or as many of the properties you like, and default values are set by a basic syntax of let {key = default} = object.

let {firstName, lastName = 'Smith'} = myParamsObject;

//Compiles to:
var firstName = myParamsObject.firstName, 
_a = myParamsObject.lastName, 
lastName = _a === void 0 ? 'Smith' : _a;

Writing an interface, type or class for the parameter object improves legibility.

type FullName = {_x000D_
  firstName: string;_x000D_
   _x000D_
  /** @default 'Smith' */_x000D_
  lastName ? : string;_x000D_
}_x000D_
_x000D_
function sayName(params: FullName) {_x000D_
_x000D_
  // Set defaults for parameter object_x000D_
  var { firstName, lastName = 'Smith'} = params;_x000D_
_x000D_
  // Do Stuff_x000D_
  var name = firstName + " " + lastName;_x000D_
  alert(name);_x000D_
}_x000D_
_x000D_
// Use it_x000D_
sayName({_x000D_
  firstName: 'Bob'_x000D_
});

You can also use eval:

FOO=bar eval 'somecommand someargs | somecommand2'

Since this answer with eval doesn't seem to please everyone, let me clarify something: when used as written, with the single quotes, it is perfectly safe. It is good as it will not launch an external process (like the accepted answer) nor will it execute the commands in an extra subshell (like the other answer).

As we get a few regular views, it's probably good to give an alternative to eval that will please everyone, and has all the benefits (and perhaps even more!) of this quick eval “trick”. Just use a function! Define a function with all your commands:

mypipe() {
    somecommand someargs | somecommand2
}

and execute it with your environment variables like this:

FOO=bar mypipe

The simplest possible way to do this is the following:

1. In the Controller method you need to extract the body from, add this parameter: [FromBody] SomeClass value

2. Declare the "SomeClass" as: class SomeClass { public string SomeParameter { get; set; } }

When the raw body is sent as json, .net core knows how to read it very easily.

I personally prefer to use the method setImageResource() like this.

ImageView myImageView = (ImageView)findViewById(R.id.myImage);
myImageView.setImageResource(R.drawable.icon);

In the function example, (read|write)DocumentsFromFile(...) having some function wrappers certainly seems to makes sense since everything in OSx and iOS seems to need three or four major classes instantiated and a bunch of properties, configured, linked, instantiated, and set, just to write "Hi" to a file, in 182 countries.

However, these examples aren't complete enough to use in a real program. The write function does not report any errors creating or writing to the file. On the read, I don't think it's a good idea to return an error that the file doesn't exist as the string that is supposed to contain the data that was read. You would want to know that it failed and why, through some notification mechanism, like an exception. Then, you can write some code that outputs what the problem is and allows the user to correct it, or "correctly" breaks the program at that point.

You would not want to just return a string with an "Error file does not exist" in it. Then, you would have to look for the error in the string from calling function each time and handle it there. You also possibly couldn't really tell if the error string was actually read from an actual file, or if it was produced from your code.

You can't even call the read like this in swift 2.2 and Xcode 7.3 because NSString(contentsOfFile...) throws an exception. It is a compile time error if you do not have any code to catch it and do something with it, like print it to stdout, or better, an error popup window, or stderr. I have heard that Apple is moving away from try catch and exceptions, but it's going to be a long move and it's not possible to write code without this. I don't know where the &error argument comes from, perhaps an older version, but NSString.writeTo[File|URL] does not currently have an NSError argument. They are defined like this in NSString.h :

public func writeToURL(url: NSURL, atomically useAuxiliaryFile: Bool, encoding enc: UInt) throws
public func writeToFile(path: String, atomically useAuxiliaryFile: Bool, encoding enc: UInt) throws
public convenience init(contentsOfURL url: NSURL, encoding enc: UInt) throws
public convenience init(contentsOfFile path: String, encoding enc: UInt) throws

Also, the file not existing is just one of a number of potential problems your program might have reading a file, such as a permissions problem, the file size, or numerous other issues that you would not even want to try to code a handler for each one of them. It's best to just assume it's all correct and catch and print, or handle, an exception if something goes amiss, besides, at this point, you don't really have a choice anyway.

Here are my rewrites :

func writeToDocumentsFile(fileName:String,value:String) {

    let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString!
    let path = documentsPath.stringByAppendingPathComponent(fileName)

    do {
        try value.writeToFile(path, atomically: true, encoding: NSUTF8StringEncoding)
    } catch let error as NSError {
        print("ERROR : writing to file \(path) : \(error.localizedDescription)")
    }

}

func readFromDocumentsFile(fileName:String) -> String {

    let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString
    let path = documentsPath.stringByAppendingPathComponent(fileName)

    var readText : String = ""

    do {
        try readText = NSString(contentsOfFile: path, encoding: NSUTF8StringEncoding) as String
    }
    catch let error as NSError {
        print("ERROR : reading from file \(fileName) : \(error.localizedDescription)")
    }
    return readText
}

we can use backticks (``) without any error.. eg: <div>"test"<div>

we can store large template(HTML) inside the backticks which was introduced in ES6 javascript standard

No need to escape any special characters

if no backticks.. we need to escape characters by appending backslash() eg:" \"test\""

String runtimeVersion = System.getProperty("java.runtime.version");

should return you a string along the lines of:

1.5.0_01-b08

That's the version of Java that Eclipse is using to run your code which is not necessarily the same version that's being used to run Eclipse itself.

Flutter Launcher Icons has been designed to help quickly generate launcher icons for both Android and iOS: https://pub.dartlang.org/packages/flutter_launcher_icons

• Add the package to your pubspec.yaml file (within your Flutter project) to use it
• Within pubspec.yaml file specify the path of the icon you wish to use for the app and then choose whether you want to use the icon for the iOS app, Android app or both.
• Run the package
• Voila! The default launcher icons have now been replaced with your custom icon

I'm hoping to add a video to the GitHub README to demonstrate it

Video showing how to run the tool can be found here.

If anyone wants to suggest improvements / report bugs, please add it as an issue on the GitHub project.

Update: As of Wednesday 24th January 2018, you should be able to create new icons without overriding the old existing launcher icons in your Flutter project.

Update 2: As of v0.4.0 (8th June 2018) you can specify one image for your Android icon and a separate image for your iOS icon.

Update 3: As of v0.5.2 (20th June 2018) you can now add adaptive launcher icons for the Android app of your Flutter project

The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.

The way you get your original array back is by using Convert.FromBase64String:

 byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);

You can try the Class Based View called RedirectView

from django.views.generic.base import RedirectView

urlpatterns = patterns('',
    url(r'^$', 'macmonster.views.home'),
    #url(r'^macmon_home$', 'macmonster.views.home'),
    url(r'^macmon_output/$', 'macmonster.views.output'),
    url(r'^macmon_about/$', 'macmonster.views.about'),
    url(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')
)

Notice how as url in the <url_to_home_view> you need to actually specify the url.

permanent=False will return HTTP 302, while permanent=True will return HTTP 301.

Alternatively you can use django.shortcuts.redirect

Update for Django 2+ versions

With Django 2+, url() is deprecated and replaced by re_path(). Usage is exactly the same as url() with regular expressions. For replacements without the need of regular expression, use path().

from django.urls import re_path

re_path(r'^.*$', RedirectView.as_view(url='<url_to_home_view>', permanent=False), name='index')

override func setSelected(selected: Bool, animated: Bool) {
    // Configure the view for the selected state

    super.setSelected(selected, animated: animated)
    let selView = UIView()

    selView.backgroundColor = UIColor( red: 5/255, green: 159/255, blue:223/255, alpha: 1.0 )
    self.selectedBackgroundView = selView
}

I provided a modification of a short answer above, but it wasnt sufficient for my needs. I needed to be able to categorize both committed lines and lines in the final code.

Your code is way more cluttered than necessary.

Replace (Not (X Is Nothing)) with X IsNot Nothing and omit the outer parentheses:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For i As Integer = 0 To comp.Container.Components.Count() - 1
        fixUIIn(comp.Container.Components(i), style)
    Next
End If

Much more readable. … Also notice that I’ve removed the redundant Step 1 and the probably redundant .Item.

But (as pointed out in the comments), index-based loops are out of vogue anyway. Don’t use them unless you absolutely have to. Use For Each instead:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For Each component In comp.Container.Components
        fixUIIn(component, style)
    Next
End If

See my answer in this thread.

intent.putExtra("Some string",very_large_obj_for_binder_buffer);

You are exceeding the binder transaction buffer by transferring large element(s) from one activity to another activity.

There are two string methods for this, find() and index(). The difference between the two is what happens when the search string isn't found. find() returns -1 and index() raises ValueError.

Using find()

>>> myString = 'Position of a character'
>>> myString.find('s')
2
>>> myString.find('x')
-1

Using index()

>>> myString = 'Position of a character'
>>> myString.index('s')
2
>>> myString.index('x')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: substring not found

From the Python manual

string.find(s, sub[, start[, end]])
Return the lowest index in s where the substring sub is found such that sub is wholly contained in s[start:end]. Return -1 on failure. Defaults for start and end and interpretation of negative values is the same as for slices.

And:

string.index(s, sub[, start[, end]])
Like find() but raise ValueError when the substring is not found.

I also had this problem, however, right-clicking on the model.tt file and running "Custom tool" didn't make any difference for me somehow, but a comment on the page Ghlouw linked to mentioned to use the menu item "BUILD > Transform All T4 Templates." which did it for me

For such a seemingly simple thing this can be a royal pain in the butt! I found a solution that works beautifully (class="video-close" is obviously particular to this button and optional)

 <a href="javascript:window.open('','_self').close();" class="video-close">Close this window</a>

Use StadiumBorder shape

              OutlineButton(
                onPressed: () {},
                child: Text("Follow"),
                borderSide: BorderSide(color: Colors.blue),
                shape: StadiumBorder(),
              )

The error means that your are trying to look up JNDI name, that is not attached to any EJB component - the component with that name does not exist.

As far as dir structure is concerned: you have to create a JAR file with EJB components. As I understand you want to play with EJB 2.X components (at least the linked example suggests that) so the structure of the JAR file should be:

/com/mypackage/MyEJB.class /com/mypackage/MyEJBInterface.class /com/mypackage/etc... etc... java classes /META-INF/ejb-jar.xml /META-INF/jboss.xml

The JAR file is more or less ZIP file with file extension changed from ZIP to JAR.

BTW. If you use JBoss 5, you can work with EJB 3.0, which are much more easier to configure. The simplest component is

@Stateless(mappedName="MyComponentName")
@Remote(MyEJBInterface.class)
public class MyEJB implements MyEJBInterface{
   public void bussinesMethod(){

   }
}

No ejb-jar.xml, jboss.xml is needed, just EJB JAR with MyEJB and MyEJBInterface compiled classes.

Now in your client code you need to lookup "MyComponentName".

I would suggest you check out the various tutorials that are coming out lately. My current fav is:

http://nodetuts.com/

Hope this helps.

Using moment.js as you asked, there is a unix method that accepts unix timestamps in seconds:

var dateString = moment.unix(value).format("MM/DD/YYYY");

To ignore this error for one instance only, add the tools:ignore="ProtectedPermissions" attribute to your permission declaration. Here is an example:

<uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE"
    tools:ignore="ProtectedPermissions" />

You have to add tools namespace in the manifest root element

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

many answers above, i will try a different way:

if you are looking for bitwise operations use only one of the marks like:

3 & 1 //==1 - and 4 | 1 //==5 - or

An awk code based on RS.

awk '1' RS=',\n' file

or:

awk 'BEGIN{RS=",\n"}1' file

This last example will be valid for any char before newline:

awk '1' RS='.\n' file

Note: dot . matches any character except line breaks.

Explanation

awk allows us to use different record (line) regex separators, we just need to include the comma before the line break (or dot for any char) in the one used for the input, the RS.

Note: what that 1 means?

Short answer, It's just a shortcut to avoid using the print statement. In awk when a condition gets matched the default action is to print the input line, example:

$ echo "test" |awk '1'
test

That's because 1 will be always true, so this expression is equivalent to:

$ echo "test"|awk '1==1'
test
$ echo "test"|awk '{if (1==1){print}}'
test

Check Record Splitting with Standard awk and Output Separators.

Operating system commands have exit codes. Look for Linux exit codes to see some material on this. The shell uses the exit codes to decide if the program worked, had problems, or failed. There are some efforts to create standard (or at least commonly-used) exit codes. See this Advanced Shell Script posting.

Using MoveToElement you will be able to find or click in whatever point you want, you have just to define the first parameter, it can be the session(winappdriver) or driver(in other ways) which is created when you instance WindowsDriver. Otherwise you can set as first parameter a grid (my case), a list, a panel or whatever you want.

Note: The top-left of your first parameter element will be the position X = 0 and Y = 0

   Actions actions = new Actions(this.session);
    int xPosition = this.session.FindElementsByAccessibilityId("GraphicView")[0].Size.Width - 530;
    int yPosition = this.session.FindElementsByAccessibilityId("GraphicView")[0].Size.Height- 150;
    actions.MoveToElement(this.xecuteClientSession.FindElementsByAccessibilityId("GraphicView")[0], xPosition, yPosition).ContextClick().Build().Perform();

Since you want to design an API using the REST architectural style you need to think about your use cases to decide which concepts are important enough to expose as resources. Should you decide to expose the status of a group as a sub-resource you could give it the following URI and implement support for both GET and PUT methods:

/groups/api/groups/{group id}/status

The downside of this approach over PATCH for modification is that you will not be able to make changes to more than one property of a group atomically and transactionally. If transactional changes are important then use PATCH.

If you do decide to expose the status as a sub-resource of a group it should be a link in the representation of the group. For example if the agent gets group 123 and accepts XML the response body could contain:

<group id="123">
  <status>Active</status>
  <link rel="/linkrels/groups/status" uri="/groups/api/groups/123/status"/>
  ...
</group>

A hyperlink is needed to fulfill the hypermedia as the engine of application state condition of the REST architectural style.

R is an environment for statistical data analysis and graphics. MATLAB's origins are in numerical computation. The basic language implementations have many features in common if you use them for for data manipulation (e.g., matrix/vector operations).

R has statistical functionality hard to find elsewhere (>2000 Packages on CRAN), and lots of statisticians use it. On the other hand, MATLAB has lots of (expensive) toolboxes for engineering applications like

• image processing/image acquisition,
• filter design,
• fuzzy logic/fuzzy control,
• partial differential equations,
• etc.

There are 3 relevant ways to send Data from client Side (HTML, Javascript, Vbscript ..etc) to Server Side (PHP, ASP, JSP ...etc)

1. HTML form Posting Request (GET or POST).
2. AJAX (This also comes under GET and POST)
3. Cookie

HTML form Posting Request (GET or POST)

This is most commonly used method, and we can send more Data through this method

AJAX

This is Asynchronous method and this has to work with secure way, here also we can send more Data.

Cookie

This is nice way to use small amount of insensitive data. this is the best way to work with bit of data.

In your case You can prefer HTML form post or AJAX. But before sending to server validate your json by yourself or use link like http://jsonlint.com/

If you have Json Object convert it into String using JSON.stringify(object), If you have JSON string send it as it is.

You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.

The solutions given here actually do not take into account multi-byte Unicode characters ("composed characters"), and could result in invalid Unicode strings.

In fact, the iOS header file which contains the declaration of substringToIndex contains the following comment:

Hint: Use with rangeOfComposedCharacterSequencesForRange: to avoid breaking up composed characters

See how to use rangeOfComposedCharacterSequenceAtIndex: to delete the last character correctly.

Rachel's solution is working fine, although you need to use the third party script from raw.githubusercontent.com

By now there is a feature they show on the landing page when advertisng the "modular" script. You can see a legend there with this structure:

<div class="labeled-chart-container">
    <div class="canvas-holder">
        <canvas id="modular-doughnut" width="250" height="250" style="width: 250px; height: 250px;"></canvas>
    </div>

<ul class="doughnut-legend">
    <li><span style="background-color:#5B90BF"></span>Core</li>
    <li><span style="background-color:#96b5b4"></span>Bar</li>
    <li><span style="background-color:#a3be8c"></span>Doughnut</li>
    <li><span style="background-color:#ab7967"></span>Radar</li>
    <li><span style="background-color:#d08770"></span>Line</li>
    <li><span style="background-color:#b48ead"></span>Polar Area</li>
</ul>
</div>

To achieve this they use the chart configuration option legendTemplate

legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"

You can find the doumentation here on chartjs.org This works for all the charts although it is not part of the global chart configuration.

Then they create the legend and add it to the DOM like this:

var legend = myPie.generateLegend();
$("#legend").html(legend);

EDIT: make sure you set this drawable as LOGO, not as your app icon like some of the commenters did.

Just make an XML drawable and put it in the resource folder "drawable" (without any density or other configuration).

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

    <item
        android:drawable="@drawable/my_logo"
        android:right="10dp"/>


</layer-list>

The last step is to set this new drawable as logo in your manifest (or on the Actionbar object in your activity)

Good luck!

specifically I want to overload Boolean.Parse to allow an int argument.

Would an extension for int work?

public static bool ToBoolean(this int source){
    // do it
    // return it
}

Then you can call it like this:

int x = 1;

bool y = x.ToBoolean();

There are quite a few ways to get the result you are after. Lets break them in categories:

ES6 Values only:

Main method for this is Object.values. But using Object.keys and Array.map you could as well get to the expected result:

Object.values(obj)
Object.keys(obj).map(k => obj[k])

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('Object.values:', Object.values(obj))_x000D_
console.log('Object.keys:', Object.keys(obj).map(k => obj[k]))

ES6 Key & Value:

Using map and ES6 dynamic/computed properties and destructuring you can retain the key and return an object from the map.

Object.keys(obj).map(k => ({[k]: obj[k]}))
Object.entries(obj).map(([k,v]) => ({[k]:v}))

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('Object.keys:', Object.keys(obj).map(k => ({_x000D_
  [k]: obj[k]_x000D_
})))_x000D_
console.log('Object.entries:', Object.entries(obj).map(([k, v]) => ({_x000D_
  [k]: v_x000D_
})))

Lodash Values only:

The method designed for this is _.values however there are "shortcuts" like _.map and the utility method _.toArray which would also return an array containing only the values from the object. You could also _.map though the _.keys and get the values from the object by using the obj[key] notation.

Note: _.map when passed an object would use its baseMap handler which is basically forEach on the object properties.

_.values(obj)
_.map(obj)
_.toArray(obj)
_.map(_.keys(obj), k => obj[k])

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('values:', _.values(obj))_x000D_
console.log('map:', _.map(obj))_x000D_
console.log('toArray:', _.toArray(obj))_x000D_
console.log('keys:', _.map(_.keys(obj), k => obj[k]))

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>

Lodash Key & Value:

// Outputs an array with [[KEY, VALUE]]
_.entries(obj)
_.toPairs(obj)

// Outputs array with objects containing the keys and values
_.map(_.entries(obj), ([k,v]) => ({[k]:v}))
_.map(_.keys(obj), k => ({[k]: obj[k]}))
_.transform(obj, (r,c,k) => r.push({[k]:c}), [])
_.reduce(obj, (r,c,k) => (r.push({[k]:c}), r), [])

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
// Outputs an array with [KEY, VALUE]_x000D_
console.log('entries:', _.entries(obj))_x000D_
console.log('toPairs:', _.toPairs(obj))_x000D_
_x000D_
// Outputs array with objects containing the keys and values_x000D_
console.log('entries:', _.map(_.entries(obj), ([k, v]) => ({_x000D_
  [k]: v_x000D_
})))_x000D_
console.log('keys:', _.map(_.keys(obj), k => ({_x000D_
  [k]: obj[k]_x000D_
})))_x000D_
console.log('transform:', _.transform(obj, (r, c, k) => r.push({_x000D_
  [k]: c_x000D_
}), []))_x000D_
console.log('reduce:', _.reduce(obj, (r, c, k) => (r.push({_x000D_
  [k]: c_x000D_
}), r), []))

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>

Note that in the above examples ES6 is used (arrow functions and dynamic properties). You can use lodash _.fromPairs and other methods to compose an object if ES6 is an issue.

Say you have defined your class like this:

    @Data
    @AllArgsConstructor(staticName = "of")
    private class Pair<P,Q> {

        public P first;
        public Q second;
    }

So when you will need to create a new instance, it will need to take the parameters and you will provide it like this as defined in the annotation.

Pair<Integer, String> pair = Pair.of(menuItemId, category);

If you define it like this, you will get the error asked for.

Pair<Integer, String> pair = new Pair(menuItemId, category);

The argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove() call vs the drop() call.

More details in the docs.

Python Classes

class name:
    def __init__(self, name):
        self.name = name
        print("name: "+name)

Somewhere else:

john = name("john")

Output:
name: john

You can simply use setInterval to create such timer in Angular, Use this Code for timer -

timeLeft: number = 60;
  interval;

startTimer() {
    this.interval = setInterval(() => {
      if(this.timeLeft > 0) {
        this.timeLeft--;
      } else {
        this.timeLeft = 60;
      }
    },1000)
  }

  pauseTimer() {
    clearInterval(this.interval);
  }

<button (click)='startTimer()'>Start Timer</button>
<button (click)='pauseTimer()'>Pause</button>

<p>{{timeLeft}} Seconds Left....</p>

Working Example

Another way using Observable timer like below -

import { timer } from 'rxjs';

observableTimer() {
    const source = timer(1000, 2000);
    const abc = source.subscribe(val => {
      console.log(val, '-');
      this.subscribeTimer = this.timeLeft - val;
    });
  }

<p (click)="observableTimer()">Start Observable timer</p> {{subscribeTimer}}

Working Example

Only ASCII or are other characters allowed too?

^\w*$

restricts (in Java) to ASCII letters/digits und underscore,

^[\pL\pN\p{Pc}]*$

also allows international characters/digits and "connecting punctuation".

Just for documentation purposes, here's what I've done for the fastest/most responsive click on desktop/tap on mobile solution that I could think of:

I replaced jQuery's on function with a modified one that, whenever the browser supports touch events, replaced all my click events with touchstart.

$.fn.extend({ _on: (function(){ return $.fn.on; })() });
$.fn.extend({
    on: (function(){
        var isTouchSupported = 'ontouchstart' in window || window.DocumentTouch && document instanceof DocumentTouch;
        return function( types, selector, data, fn, one ) {
            if (typeof types == 'string' && isTouchSupported && !(types.match(/touch/gi))) types = types.replace(/click/gi, 'touchstart');
            return this._on( types, selector, data, fn);
        };
    }()),
});

Usage than would be the exact same as before, like:

$('#my-button').on('click', function(){ /* ... */ });

But it would use touchstart when available, click when not. No delays of any kind needed :D

This is probably not the main reason why the create_all() method call doesn't work for people, but for me, the cobbled together instructions from various tutorials have it such that I was creating my db in a request context, meaning I have something like:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

def get_db():
  if 'db' not in g:
    g.db = SQLAlchemy(current_app)
  return g.db

I also have a separate cli command that also does the create_all:

# tasks/db.py
from lib.db import get_db

@current_app.cli.command('init-db')
def init_db():
  db = get_db()
  db.create_all()

I also am using a application factory.

When the cli command is run, a new app context is used, which means a new db is used. Furthermore, in this world, an import model in the init_db method does not do anything, because it may be that your model file was already loaded(and associated with a separate db).

The fix that I came around to was to make sure that the db was a single global reference:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

db = None
def get_db():
  global db
  if not db:
    db = SQLAlchemy(current_app)
  return db

I have not dug deep enough into flask, sqlalchemy, or flask-sqlalchemy to understand if this means that requests to the db from multiple threads are safe, but if you're reading this you're likely stuck in the baby stages of understanding these concepts too.

I had the same error when we imported a key into a keystore that was build using a 64bit OpenSSL Version. When we followed the same procedure to import the key into a keystore that was build using a 32 bit OpenSSL version everything went fine.

If you could access the file system of a user with javascript, image the bad that could happen.

However, you can use File System Object but this will work only in IE:

http://bytes.com/topic/javascript/answers/460516-check-file-size-javascript

This code helped me get this behaviour: With a list a,b,c, I should get compared ab, ac and bc, but any other pair would be excess / not needed.

import java.util.*;
import static java.lang.System.out;

// rl = rawList; lr = listReversed
ArrayList<String> rl = new ArrayList<String>();
ArrayList<String> lr = new ArrayList<String>();
rl.add("a");
rl.add("b");
rl.add("c");
rl.add("d");
rl.add("e");
rl.add("f");

lr.addAll(rl);
Collections.reverse(lr);

for (String itemA : rl) {
    lr.remove(lr.size()-1);
        for (String itemZ : lr) {
        System.out.println(itemA + itemZ);
    }
}

The loop goes as like in this picture: Triangular comparison visual example

or as this:

   |   f    e    d    c    b   a
   ------------------------------
a  |  af   ae   ad   ac   ab   ·
b  |  bf   be   bd   bc   ·   
c  |  cf   ce   cd   ·      
d  |  df   de   ·         
e  |  ef   ·            
f  |  ·               

total comparisons is a triangular number (n * n-1)/2

I used this at the end of the web.php or api.php file and it worked perfectly:

URL::forceScheme('https');

At least for the GitHub Flavoured Markdown, you can give the illusion by making all the non-header row entries bold with the regular __ or ** formatting:

|Regular | text | in header | turns bold |
|-|-|-|-|
| __So__ | __bold__ | __all__ | __table entries__ |
| __and__ | __it looks__ | __like a__ | __"headerless table"__ |

You can use it in a more compact way as:

var tifs = {1: 'Joe', 2: 'Jane'};
...

return (
   <select id="tif" name="tif" onChange={this.handleChange}>  
      { Object.entries(tifs).map((t,k) => <option key={k} value={t[0]}>{t[1]}</option>) }          
   </select>
)

And another slightly different flavour:

 Object.entries(tifs).map(([key,value],i) => <option key={i} value={key}>{value}</option>)  

innerHTML is fine and still valid. Use it all the time on projects big and small. I just flipped to an open tab in my IDE and there was one right there.

 document.getElementById("data-progress").innerHTML = "<img src='../images/loading.gif'/>";

Not much has changed in js + dom manipulation since 2005, other than the addition of more libraries. You can easily set other properties such as

   uploadElement.style.width = "100%";

If you use

android:taskAffinity="myApp.widget.notify.activity"
android:excludeFromRecents="true"

in your AndroidManifest.xml file for the Activity to launch, you have to use the following in your intent:

Intent notificationClick = new Intent(context, NotifyActivity.class);
    Bundle bdl = new Bundle();
    bdl.putSerializable(NotifyActivity.Bundle_myItem, myItem);
    notificationClick.putExtras(bdl);
    notificationClick.setData(Uri.parse(notificationClick.toUri(Intent.URI_INTENT_SCHEME) + myItem.getId()));
    notificationClick.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);  // schließt tasks der app und startet einen seperaten neuen

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
    stackBuilder.addParentStack(NotifyActivity.class);
    stackBuilder.addNextIntent(notificationClick);

    PendingIntent notificationPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.setContentIntent(notificationPendingIntent);

Important is to set unique data e.g. using an unique id like:

notificationClick.setData(Uri.parse(notificationClick.toUri(Intent.URI_INTENT_SCHEME) + myItem.getId()));

One reason to use the body in a delete request is for optimistic concurrency control.

You read version 1 of a record.

GET /some-resource/1
200 OK { id:1, status:"unimportant", version:1 }

Your colleague reads version 1 of the record.

GET /some-resource/1
200 OK { id:1, status:"unimportant", version:1 }

Your colleague changes the record and updates the database, which updates the version to 2:

PUT /some-resource/1 { id:1, status:"important", version:1 }
200 OK { id:1, status:"important", version:2 }

You try to delete the record:

DELETE /some-resource/1 { id:1, version:1 }
409 Conflict

You should get an optimistic lock exception. Re-read the record, see that it's important, and maybe not delete it.

Another reason to use it is to delete multiple records at a time (for example, a grid with row-selection check-boxes).

DELETE /messages
[{id:1, version:2},
{id:99, version:3}]
204 No Content

Notice that each message has its own version. Maybe you can specify multiple versions using multiple headers, but by George, this is simpler and much more convenient.

This works in Tomcat (7.0.52) and Spring MVC (4.05), possibly w earlier versions too:

@RestController
public class TestController {

    @RequestMapping(value="/echo-delete", method = RequestMethod.DELETE)
    SomeBean echoDelete(@RequestBody SomeBean someBean) {
        return someBean;
    }
}

You either need to import the project as a Gradle project from within Idea. When you add a dependency you need to open the Gradle window and perform a refresh.

Alternatively generate the project files from gradle with this:

build.gradle:

apply plugin: 'idea'

And then run:

$ gradle idea

If you modify the dependencies you will need to rerun the above again.

The correct way to 'solve' it is to close the connection and forget about the client. The client has closed the connection while you where still writing to it, so he doesn't want to know you, so that's it, isn't it?

Quite simple, with a * wildcard.

cp -r Folder1/* Folder2/

But according to your example recursion is not needed so the following will suffice:

cp Folder1/* Folder2/

EDIT:

Or skip the mkdir Folder2 part and just run:

cp -r Folder1 Folder2

For anyone that this might be handy for, here is a jQuery dependent function I had success with for applying a CSS animation via a CSS class, then getting a callback from afterwards. It may not work perfectly since I had it being used in a Backbone.js App, but maybe useful.

var cssAnimate = function(cssClass, callback) {
    var self = this;

    // Checks if correct animation has ended
    var setAnimationListener = function() {
        self.one(
            "webkitAnimationEnd oanimationend msAnimationEnd animationend",
            function(e) {
                if(
                    e.originalEvent.animationName == cssClass &&
                    e.target === e.currentTarget
                ) {
                    callback();
                } else {
                    setAnimationListener();
                }
            }
        );
    }

    self.addClass(cssClass);
    setAnimationListener();
}

I used it kinda like this

cssAnimate.call($("#something"), "fadeIn", function() {
    console.log("Animation is complete");
    // Remove animation class name?
});

Original idea from http://mikefowler.me/2013/11/18/page-transitions-in-backbone/

And this seems handy: http://api.jqueryui.com/addClass/

Update

After struggling with the above code and other options, I would suggest being very cautious with any listening for CSS animation ends. With multiple animations going on, this can get messy very fast for event listening. I would strongly suggest an animation library like GSAP for every animation, even the small ones.

Set JAVA_HOME in the environment variables as D:\Program Files\IBM\SDP\jdk Do not give any quotes or semicolon. It's works for me.Please try the solution. Actually in ant.bat it checks for appropriate JAVA_HOME in case if ant.bat not able to find it then it's JAVA_HOME points the default JRE.

You can also use ISNULL and a select statement to get this result

SELECT
Table1.ID,
ISNULL((SELECT 'TRUE' FROM TABLE2 WHERE TABLE2.ID = TABEL1.ID),'FALSE') AS columName,
etc
FROM TABLE1

as your variable bool is pointing to a null, you will always get a NullPointerException, you need to initialize the variable first somewhere with a not null value, and then modify it.

The big difference is perfectly explained here.

Basically, lightweight tags are just pointers to specific commits. No further information is saved; on the other hand, annotated tags are regular objects, which have an author and a date and can be referred because they have their own SHA key.

If knowing who tagged what and when is relevant for you, then use annotated tags. If you just want to tag a specific point in your development, no matter who and when did that, then lightweight tags are good enough.

Normally you'd go for annotated tags, but it is really up to the Git master of the project.

The solution is to install a browser plugin.

A web site which issues HTTP Header X-Frame-Options with a value of DENY (or SAMEORIGIN with a different server origin) cannot be integrated into an IFRAME... unless you change this behavior by installing a Browser plugin which ignores the X-Frame-Options Header (e.g. Chrome's Ignore X-Frame Headers).

Note that this not recommended at all for security reasons.

What moves origin/HEAD "organically"?

• git clone sets it once to the spot where HEAD is on origin
  • it serves as the default branch to checkout after cloning with git clone

What does HEAD on origin represent?

• on bare repositories (often repositories “on servers”) it serves as a marker for the default branch, because git clone uses it in such a way
• on non-bare repositories (local or remote), it reflects the repository’s current checkout

What sets origin/HEAD?

• git clone fetches and sets it
• it would make sense if git fetch updates it like any other reference, but it doesn’t
• git remote set-head origin -a fetches and sets it
  • useful to update the local knowledge of what remote considers the “default branch”

Trivia

• origin/HEAD can also be set to any other value without contacting the remote: git remote set-head origin <branch>
  • I see no use-case for this, except for testing
• unfortunately nothing is able to set HEAD on the remote
• older versions of git did not know which branch HEAD points to on the remote, only which commit hash it finally has: so it just hopefully picked a branch name pointing to the same hash

Think that JavaScriptDevelopmentTools might do it. Although, I have eclipse indigo, and I'm pretty sure it does that kind of thing automatically.

My problem was that under Build Phases -> Compile Sources, I added a compiler flag for a file, but I had misspelled it. It was supposed to be:

-fno-obj-arc

to show that this file does not use ARC.

I have seen this once. Are the users requesting different amounts of data? I found that even if you can configure a binding for data payloads (i.e. maxReceivedMessageSize), the httpRuntime maxRequestLength trumps the WCF setting, so if IIS is trying to serve a request that exceeds that, it exhibits this behavior.

Think of it like this:

If maxReceivedMessageSize is 12MB in your WCF behavior, and maxRequestLength is 4MB (default), IIS wins.

You would need an HTTP module that looked at the requested resource and if it was a css or js, it would tack on the Access-Control-Allow-Origin header with the requestors URL, unless you want it wide open with '*'.

Although Chang's answer explains how to plot multiple times on the same figure, in this case you might be better off in this case using a groupby and unstacking:

(Assuming you have this in dataframe, with datetime index already)

In [1]: df
Out[1]:
            value  
datetime                         
2010-01-01      1  
2010-02-01      1  
2009-01-01      1  

# create additional month and year columns for convenience
df['Month'] = map(lambda x: x.month, df.index)
df['Year'] = map(lambda x: x.year, df.index)    

In [5]: df.groupby(['Month','Year']).mean().unstack()
Out[5]:
       value      
Year    2009  2010
Month             
1          1     1
2        NaN     1

Now it's easy to plot (each year as a separate line):

df.groupby(['Month','Year']).mean().unstack().plot()

it'matter of *unix permissions, gain root acces, for example by typing

sudo su
[then type your password]

and try to do what you have to do

For IE there is fireEvent() method. Don't know if that works for other browsers.

In the past, I've solved this kind of problem with StringTemplate and Groovy Templates.

Ultimately, the decision of using a templating engine or not should be based on the following factors:

• Will you have many of these templates in the application?
• Do you need the ability to modify the templates without restarting the application?
• Who will be maintaining these templates? A Java programmer or a business analyst involved on the project?
• Will you need to the ability to put logic in your templates, like conditional text based on values in the variables?
• Will you need the ability to include other templates in a template?

If any of the above applies to your project, I would consider using a templating engine, most of which provide this functionality, and more.

Depends on your needs there is an addition to accepted answer. You may also implement it like this:

var parseCompletion: (() ->Void)!

and later in some func assign to it

func someHavyFunc(completion: @escaping () -> Void){
    self.parseCompletion = completion
}

and in some second function use it

func someSecondFunc(){
    if let completion = self.parseCompletion {
        completion()
    }
}

note that @escaping parameter is a mandatory here

There's an alternative, explained in String manifesto

extension String : BidirectionalCollection {
    subscript(i: Index) -> Character { return characters[i] }
}

summary - popular js frameworks like jquery or dojo offer one commented, pretty formatted version with comments for DEVELOPMENT and a minified version (quicker) without comments etc. for PRODUCTION

jquery.js - development jquery.min.js - production

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(10 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
    // ...
});

The dispatch_after(_:_:_:) function takes three parameters:

a delay
a dispatch queue
a block or closure

The dispatch_after(_:_:_:) function invokes the block or closure on the dispatch queue that is passed to the function after a given delay. Note that the delay is created using the dispatch_time(_:_:) function. Remember this because we also use this function in Swift.

I recommend to go through the tutorial Raywenderlich Dispatch tutorial

In SQL Server 2008 you can insert multiple rows using a single SQL INSERT statement.

INSERT INTO MyTable ( Column1, Column2 ) VALUES
( Value1, Value2 ), ( Value1, Value2 )

For reference to this have a look at MOC Course 2778A - Writing SQL Queries in SQL Server 2008.

For example:

INSERT INTO MyTable
  ( Column1, Column2, Column3 )
VALUES
  ('John', 123, 'Lloyds Office'), 
  ('Jane', 124, 'Lloyds Office'), 
  ('Billy', 125, 'London Office'),
  ('Miranda', 126, 'Bristol Office');

Use like this on dropdown change
$("#assetgroupSelect").change(function(){
    $("#idValue").val($this.val());
})

SELECT STRCMP("string1", "string2");

this returns 0 if the strings are equal.

• If string1 = string2, this function returns 0 (ignoring the case)
• If string1 < string2, this function returns -1
• If string1 > string2, this function returns 1

There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..

At the very simplest, you would catch urllib2.URLError:

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    raise MyException("There was an error: %r" % e)

The following should capture the specific error raised when the connection times out:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    # For Python 2.6
    if isinstance(e.reason, socket.timeout):
        raise MyException("There was an error: %r" % e)
    else:
        # reraise the original error
        raise
except socket.timeout, e:
    # For Python 2.7
    raise MyException("There was an error: %r" % e)

SOLVED! I register to stockoverflow just to share to you the only solution (at least in ASP.NET/IE/FF/Chrome) that works! The idea is to replace innerHTML value of a div by its current innerHTML value.

Here is the HTML snippet:

<div class="content-2" id="divGranite">
<h2>Granite Purchase</h2>
<IFRAME  runat="server" id="frameGranite" src="Jobs-granite.aspx" width="820px" height="300px" frameborder="0" seamless  ></IFRAME>
</div>

And my Javascript code:

function refreshGranite() {           
   var iframe = document.getElementById('divGranite')
   iframe.innerHTML = iframe.innerHTML;
}

Hope this helps.

I had a similar problem quite recently. In my case:

1. I downloaded an artifact from some less popular Maven repo

2. This repo dissappeared over this year

3. Now builds fail, even if I have this artifact and its pom.xml in my local repo

Workaround:

delete _remote.repositories file in your local repo, where this artifact resides. Now the project builds.

The solution here worked for me. It's a matter of importing the library to the libs folder, then modifying the build.gradle file and then cleaning with gradlew.

All the tools you would need are already available to you on most modern distributions of Linux.

As several have pointed out you can pipe the serial data through netcat. However you would need to relaunch a new instance each time there is a connection. In order to have this persist between connections you can create a xinetd service using the following configuration:

service testservice
{
    port        = 5900
    socket_type = stream
    protocol    = tcp
    wait        = yes
    user        = root
    server      = /usr/bin/netcat
    server_args = "-l 5900 < /dev/ttyS0"
}

Be sure to change the /dev/ttyS0 to match the serial device you are attempting to interface with.

Hi Guys you cant convert directly string to bigdecimal

you need to first convert it into long after that u will convert big decimal

String currency = "135.69"; 
Long rate1=Long.valueOf((currency ));            
System.out.println(BigDecimal.valueOf(rate1));

I know this is a bit old but the answer in short would be <load-on-startup> both occurrences have given the same id which is 1 twice. This may confuse loading sequence.

padding: 0px solves the horizontal centering

whereas,

setting line-height equal to or less than the height of the button solves the vertical alignment.

after some test: If you send an email to an outlook client, and the subject is >77 chars, and it needs to use "=?ISO" inside the subject (in my case because of accents) then OutLook will "cut" the subject in the middle of it and mesh it all that comes after, including body text, attaches, etc... all a mesh!

I have several examples like this one:

Subject: =?ISO-8859-1?Q?Actas de la obra N=BA.20100154 (Expediente N=BA.20100182) "NUEVA RED FERROVIARIA.=

TRAMO=20BEASAIN=20OESTE(Pedido=20PC10/00123-125),=20BEASAIN".?=

To:

As you see, in the subject line it cutted on char 78 with a "=" followed by 2 or 3 line feeds, then continued with the rest of the subject baddly.

It was reported to me from several customers who all where using OutLook, other email clients deal with those subjects ok.

If you have no ISO on it, it doesn't hurt, but if you add it to your subject to be nice to RFC, then you get this surprise from OutLook. Bit if you don't add the ISOs, then iPhone email will not understand it(and attach files with names using such characters will not work on iPhones).

The answer of shimi_tap is enough. What to be remembered is that choosing only what you need. Choose from {icon, name, theme, label}. I added tools:replace="android:icon,android:theme", it does not work. I added tools:replace="android:icon,android:theme,android:label,android:name", it does not work. It works when I added tools:replace="android:icon,android:theme,android:label". So find out what the conflict exactly is in your manifest files.

You can use the OfType operator. It ignores null values in the source sequence. Just use the same type as MyProperty and it won't filter out anything else.

// given:
// public T MyProperty { get; }
var nonNullItems = list.Select(x => x.MyProperty).OfType<T>();

I would advise against this though. If you want to pick non-null values, what can be more explicit than saying you want "the MyProperties from the list that are not null"?

Different web stacks do support different lengths of http-requests. I know from experience that the early stacks of Safari only supported 4000 characters and thus had difficulty handling ASP.net pages because of the USER-STATE. This is even for POST, so you would have to check the browser and see what the stack limit is. I think that you may reach a limit even on newer browsers. I cannot remember but one of them (IE6, I think) had a limit of 16-bit limit, 32,768 or something.

Since the rules are running in JavaScript, why not disable them using javascript (or in my examples case, jQuery)?

$('#fieldId').attr('disabled', 'disabled'); //Disable
$('#fieldId').removeAttr('disabled'); //Enable

UPDATE

The attr function is no longer the primary approach to this, as was pointed out in the comments below. This is now done with the prop function.

$( "input" ).prop( "disabled", true ); //Disable
$( "input" ).prop( "disabled", false ); //Enable

Create unique constraint that two numbers together CANNOT together be repeated:

ALTER TABLE someTable
ADD UNIQUE (col1, col2)

For plaintext email using JavaScript, you may also use \r with encodeURIComponent().

For example, this message:

hello\rthis answer is now well formated\rand it contains good knowleadge\rthat is why I am up voting

URI Encoded, results in:

hello%0Dthis%20answer%20is%20now%20well%20formated%0Dand%20it%20contains%20good%20knowleadge%0Dthat%20is%20why%20I%20am%20up%20voting

And, using the href:

mailto:[email protected]?body=hello%0Dthis%20answer%20is%20now%20well%20formated%0Dand%20it%20contains%20good%20knowleadge%0Dthat%20is%20why%20I%20am%20up%20voting

Will result in the following email body text:

hello
this answer is now well formated
and it contains good knowleadge
that is why I am up voting

There is no need for any External libraries, the JRE System libraries provide all you need.

I am infering that you have a org.w3c.dom.Document object you would like to write to a file

To do that, you use a javax.xml.transform.Transformer:

import org.w3c.dom.Document
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.dom.DOMSource; 
import javax.xml.transform.stream.StreamResult; 

public class XMLWriter {
    public static void writeDocumentToFile(Document document, File file) {

        // Make a transformer factory to create the Transformer
        TransformerFactory tFactory = TransformerFactory.newInstance();

        // Make the Transformer
        Transformer transformer = tFactory.newTransformer();

        // Mark the document as a DOM (XML) source
        DOMSource source = new DOMSource(document);

        // Say where we want the XML to go
        StreamResult result = new StreamResult(file);

        // Write the XML to file
        transformer.transform(source, result);
    }
}

An easier and more standard way to simulate a mouse click would be directly using the event constructor to create an event and dispatch it.

Though the MouseEvent.initMouseEvent() method is kept for backward compatibility, creating of a MouseEvent object should be done using the MouseEvent() constructor.

var evt = new MouseEvent("click", {
    view: window,
    bubbles: true,
    cancelable: true,
    clientX: 20,
    /* whatever properties you want to give it */
});
targetElement.dispatchEvent(evt);

Demo: http://jsfiddle.net/DerekL/932wyok6/

This works on all modern browsers. For old browsers including IE, MouseEvent.initMouseEvent will have to be used unfortunately though it's deprecated.

var evt = document.createEvent("MouseEvents");
evt.initMouseEvent("click", canBubble, cancelable, view,
                   detail, screenX, screenY, clientX, clientY,
                   ctrlKey, altKey, shiftKey, metaKey,
                   button, relatedTarget);
targetElement.dispatchEvent(evt);

use window.location.href = url

dynDiv.Attributes["class"] = "myCssClass";

We can make use of LocalDate and ChronoUnit java library, Below code is working fine. Date should be in format yyyy-MM-dd.

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;
import java.util.*;
class Solution {
    public int daysBetweenDates(String date1, String date2) {
        LocalDate dt1 = LocalDate.parse(date1);
        LocalDate dt2= LocalDate.parse(date2);

        long diffDays = ChronoUnit.DAYS.between(dt1, dt2);

        return Math.abs((int)diffDays);
    }
}

If you are testing asynchronous code, you need to make sure to place done() in the callback of that asynchronous code. I had that issue when testing http requests to a REST API.

There is a class in accordian which just adjust height from height:auto or 0 to the accordian div.

if you remove 'in' class and when you click on it, bootstrap adds 'in' class again and now content will be visible

<div id="collapseOne" class="accordion-body collapse">
....
</div>

You cannot guarantee that the automatically-generated WSDL will match the WSDL from which you create the service interface.

In your scenario, you should place the WSDL file on your web site somewhere, and have consumers use that URL. You should disable the Documentation protocol in the web.config so that "?wsdl" does not return a WSDL. See <protocols> Element.

Also, note the first paragraph of that article:

This topic is specific to a legacy technology. XML Web services and XML Web service clients should now be created using Windows Communication Foundation (WCF).

It's really this simple

var dragged = false
window.addEventListener('mousedown', function () { dragged = false })
window.addEventListener('mousemove', function () { dragged = true })
window.addEventListener('mouseup', function() {
        if (dragged == true) { return }
        console.log("CLICK!! ")
})

You honestly do not want to add a threshold allowing a small movement. The above is the correct, normal, feel of clicking on all desktop interfaces.

Just try it.

You can easily add an event if you like.

Use this one

public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

@Test
public void testInsertObject() throws Exception { 
    String url = BASE_URL + "/object";
    ObjectBean anObject = new ObjectBean();
    anObject.setObjectId("33");
    anObject.setUserId("4268321");
    //... more
    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRAP_ROOT_VALUE, false);
    ObjectWriter ow = mapper.writer().withDefaultPrettyPrinter();
    String requestJson=ow.writeValueAsString(anObject );

    mockMvc.perform(post(url).contentType(APPLICATION_JSON_UTF8)
        .content(requestJson))
        .andExpect(status().isOk());
}

As described in the comments, this works because the object is converted to json and passed as the request body. Additionally, the contentType is defined as Json (APPLICATION_JSON_UTF8).

Why not try using the following:

$dateTimeString = $aDateString." ".$aTimeString;
$dueDateTime = Carbon::createFromFormat('Y-m-d H:i:s', $dateTimeString, 'Europe/London');   

As mentioned in other answers, you'll always get the QuotaExceededError in Safari Private Browser Mode on both iOS and OS X when localStorage.setItem (or sessionStorage.setItem) is called.

One solution is to do a try/catch or Modernizr check in each instance of using setItem.

However if you want a shim that simply globally stops this error being thrown, to prevent the rest of your JavaScript from breaking, you can use this:

https://gist.github.com/philfreo/68ea3cd980d72383c951

// Safari, in Private Browsing Mode, looks like it supports localStorage but all calls to setItem
// throw QuotaExceededError. We're going to detect this and just silently drop any calls to setItem
// to avoid the entire page breaking, without having to do a check at each usage of Storage.
if (typeof localStorage === 'object') {
    try {
        localStorage.setItem('localStorage', 1);
        localStorage.removeItem('localStorage');
    } catch (e) {
        Storage.prototype._setItem = Storage.prototype.setItem;
        Storage.prototype.setItem = function() {};
        alert('Your web browser does not support storing settings locally. In Safari, the most common cause of this is using "Private Browsing Mode". Some settings may not save or some features may not work properly for you.');
    }
}

I was facing similar issue with openCV on the python:3.7-slim docker box. Following did the trick for me :

apt-get install build-essential libglib2.0-0 libsm6 libxext6 libxrender-dev

Please see if this helps !

Since you return to the client just String and its content type == 'text/plain', there is no any chance for default converters to determine how to convert String response to the FFSampleResponseHttp object.

The simple way to fix it:

• remove expected-response-type from <int-http:outbound-gateway>
• add to the replyChannel1 <json-to-object-transformer>

Otherwise you should write your own HttpMessageConverter to convert the String to the appropriate object.

To make it work with MappingJackson2HttpMessageConverter (one of default converters) and your expected-response-type, you should send your reply with content type = 'application/json'.

If there is a need, just add <header-enricher> after your <service-activator> and before sending a reply to the <int-http:inbound-gateway>.

So, it's up to you which solution to select, but your current state doesn't work, because of inconsistency with default configuration.

UPDATE

OK. Since you changed your server to return FfSampleResponseHttp object as HTTP response, not String, just add contentType = 'application/json' header before sending the response for the HTTP and MappingJackson2HttpMessageConverter will do the stuff for you - your object will be converted to JSON and with correct contentType header.

From client side you should come back to the expected-response-type="com.mycompany.MyChannel.model.FFSampleResponseHttp" and MappingJackson2HttpMessageConverter should do the stuff for you again.

Of course you should remove <json-to-object-transformer> from you message flow after <int-http:outbound-gateway>.

And as suggested above by Siu Ching Pong -Asuka Kenji with the function which in my opinion makes more sense and leaves you with the convenience of the map type without the function wrapper around:

   // romanNumeralDict returns map[int]string dictionary, since the return
       // value is always the same it gives the pseudo-constant output, which
       // can be referred to in the same map-alike fashion.
       var romanNumeralDict = func() map[int]string { return map[int]string {
            1000: "M",
            900:  "CM",
            500:  "D",
            400:  "CD",
            100:  "C",
            90:   "XC",
            50:   "L",
            40:   "XL",
            10:   "X",
            9:    "IX",
            5:    "V",
            4:    "IV",
            1:    "I",
          }
        }

        func printRoman(key int) {
          fmt.Println(romanNumeralDict()[key])
        }

        func printKeyN(key, n int) {
          fmt.Println(strings.Repeat(romanNumeralDict()[key], n))
        }

        func main() {
          printRoman(1000)
          printRoman(50)
          printKeyN(10, 3)
        }

In addition to the answers here...

if you are using jquery on the client side, this worked for me:

Java:

@RequestMapping(value = "/ajax/search/sync") 
public String sync(@RequestBody Foo json) {

Jquery (you need to include Douglas Crockford's json2.js to have the JSON.stringify function):

$.ajax({
    type: "post",
    url: "sync", //your valid url
    contentType: "application/json", //this is required for spring 3 - ajax to work (at least for me)
    data: JSON.stringify(jsonobject), //json object or array of json objects
    success: function(result) {
        //do nothing
    },
    error: function(){
        alert('failure');
    }
});

If you are using a library or another class which throws an exception, you should rethrow it. Here is an example. Example2.java is like library and Example.java uses it's object. Main.java is an example to handle this Exception. You should show a meaningful message and (if needed) stack trace to the user in the calling side.

Main.java

public class Main {
public static void main(String[] args) {
    Example example = new Example();

    try {
        Example2 obj = example.doExample();

        if(obj == null){
            System.out.println("Hey object is null!");
        }
    } catch (Exception e) {
        System.out.println("Congratulations, you caught the exception!");
        System.out.println("Here is stack trace:");
        e.printStackTrace();
    }
}
}

Example.java

/**
 * Example.java
 * @author Seval
 * @date 10/22/2014
 */
public class Example {
    /**
     * Returns Example2 object
     * If there is no Example2 object, throws exception
     * 
     * @return obj Example2
     * @throws Exception
     */
    public Example2 doExample() throws Exception {
        try {
            // Get the object
            Example2 obj = new Example2();

            return obj;

        } catch (Exception e) {
            // Log the exception and rethrow
            // Log.logException(e);
            throw e;
        }

    }
}

Example2.java

 /**
 * Example2.java
 * @author Seval
 *
 */
public class Example2 {
    /**
     * Constructor of Example2
     * @throws Exception
     */
    public Example2() throws Exception{
        throw new Exception("Please set the \"obj\"");
    }

}

An alternative to kubi's answer is to have a look at the .git/config file which shows the local repository configuration:

cat .git/config

For Django 2.1.1 add following lines to urls.py

from django.contrib import admin

# Admin Site Config
admin.sites.AdminSite.site_header = 'My site admin header'
admin.sites.AdminSite.site_title = 'My site admin title'
admin.sites.AdminSite.index_title = 'My site admin index'

You're not going to be able to modify the caller's shell because it's in a different process context. When child processes inherit your shell's variables, they're inheriting copies themselves.

One thing you can do is to write a script that emits the correct commands for tcsh or sh based how it's invoked. If you're script is "setit" then do:

ln -s setit setit-sh

and

ln -s setit setit-csh

Now either directly or in an alias, you do this from sh

eval `setit-sh`

or this from csh

eval `setit-csh`

setit uses $0 to determine its output style.

This is reminescent of how people use to get the TERM environment variable set.

The advantage here is that setit is just written in whichever shell you like as in:

#!/bin/bash
arg0=$0
arg0=${arg0##*/}
for nv in \
   NAME1=VALUE1 \
   NAME2=VALUE2
do
   if [ x$arg0 = xsetit-sh ]; then
      echo 'export '$nv' ;'
   elif [ x$arg0 = xsetit-csh ]; then
      echo 'setenv '${nv%%=*}' '${nv##*=}' ;'
   fi
done

with the symbolic links given above, and the eval of the backquoted expression, this has the desired result.

To simplify invocation for csh, tcsh, or similar shells:

alias dosetit 'eval `setit-csh`'

or for sh, bash, and the like:

alias dosetit='eval `setit-sh`'

One nice thing about this is that you only have to maintain the list in one place. In theory you could even stick the list in a file and put cat nvpairfilename between "in" and "do".

This is pretty much how login shell terminal settings used to be done: a script would output statments to be executed in the login shell. An alias would generally be used to make invocation simple, as in "tset vt100". As mentioned in another answer, there is also similar functionality in the INN UseNet news server.

First set the isTranslucent property of navigationBar to false to get the desired colour. Then change the navigationBar colour like this:

@IBOutlet var NavigationBar: UINavigationBar!

NavigationBar.isTranslucent = false
NavigationBar.barTintColor = UIColor (red: 117/255, green: 23/255, blue: 49/255, alpha: 1.0)

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

If you define

    #!/bin/bash
        fun1(){
          echo "Fun1 from file1 $1"
        }
fun1 Hello
. file2 
fun1 Hello
exit 0

in file1(chmod 750 file1) and file2

   fun1(){
      echo "Fun1 from file2 $1"
    }
    fun2(){
      echo "Fun1 from file1 $1"
    }

and run ./file2 you'll get Fun1 from file1 Hello Fun1 from file2 Hello Surprise!!! You overwrite fun1 in file1 with fun1 from file2... So as not to do so you must

declare -f pr_fun1=$fun1
. file2
unset -f fun1
fun1=$pr_fun1
unset -f pr_fun1
fun1 Hello

it's save your previous definition for fun1 and restore it with the previous name deleting not needed imported one. Every time you import functions from another file you may remember two aspects:

1. you may overwrite existing ones with the same names(if that the thing you want you must preserve them as described above)
2. import all content of import file(functions and global variables too) Be careful! It's dangerous procedure

If you want to rank just one person you can do the following:

SELECT COUNT(Age) + 1
 FROM PERSON
WHERE(Age < age_to_rank)

This ranking corresponds to the oracle RANK function (Where if you have people with the same age they get the same rank, and the ranking after that is non-consecutive).

It's a little bit faster than using one of the above solutions in a subquery and selecting from that to get the ranking of one person.

This can be used to rank everyone but it's slower than the above solutions.

SELECT
  Age AS age_var,
(
  SELECT COUNT(Age) + 1
  FROM Person
  WHERE (Age < age_var)
 ) AS rank
 FROM Person

Your code is in the <head> => runs before the elements are rendered, so document.getElementById('compute'); returns null, as MDN promise...

element = document.getElementById(id);
element is a reference to an Element object, or null if an element with the specified ID is not in the document.

MDN

Solutions:

1. Put the scripts in the bottom of the page.
2. Call the attach code in the load event.
3. Use jQuery library and it's DOM ready event.

What is the jQuery ready event and why is it needed?
(why no just JavaScript's load event):

While JavaScript provides the load event for executing code when a page is rendered, this event does not get triggered until all assets such as images have been completely received. In most cases, the script can be run as soon as the DOM hierarchy has been fully constructed. The handler passed to .ready() is guaranteed to be executed after the DOM is ready, so this is usually the best place to attach all other event handlers...

ready docs

$a = [1 => 'funny', 3 => 'meshgaat', 15 => 'obi', 2 => 'OMER'];  

$b = 'omer';

function checkArr($x,$array)
{
    $arr = array_values($array);
    $arrlength = count($arr);
    $z = strtolower($x);

    for ($i = 0; $i < $arrlength; $i++) {
        if ($z == strtolower($arr[$i])) {
            echo "yes";
        }  
    } 
};

checkArr($b, $a);

The answer of Pardeep Jain can be useful for static data, but what if we have an array in JSON?

For example, we have i values and get the value of id field

alert(obj[i].id); //works!

But what if we need key with spaces?

In this case, the following construction can help (without point between [] blocks):

alert(obj[i]["No. of interfaces"]); //works too!

When you need the probabilities as well... The following gets the AUC value and plots it all in one shot.

from sklearn.metrics import plot_roc_curve

plot_roc_curve(m,xs,y)

When you have the probabilities... you can't get the auc value and plots in one shot. Do the following:

from sklearn.metrics import roc_curve

fpr,tpr,_ = roc_curve(y,y_probas)
plt.plot(fpr,tpr, label='AUC = ' + str(round(roc_auc_score(y,m.oob_decision_function_[:,1]), 2)))
plt.legend(loc='lower right')

HTML:

<video
    id="video-active"
    class="video-active"
    width="640"
    height="390"
    controls="controls">
    <source src="myvideo.mp4" type="video/mp4">
</video>
<div id="current">0:00</div>
<div id="duration">0:00</div>

JavaScript:

$(document).ready(function(){
  $("#video-active").on(
    "timeupdate", 
    function(event){
      onTrackedVideoFrame(this.currentTime, this.duration);
    });
});

function onTrackedVideoFrame(currentTime, duration){
    $("#current").text(currentTime); //Change #current to currentTime
    $("#duration").text(duration)
}

Notes:

Every 15 to 250ms, or whenever the MediaController's media controller position changes, whichever happens least often, the user agent must queue a task to fire a simple event named timeupdate at the MediaController.

http://www.w3.org/TR/html5/embedded-content-0.html#media-controller-position

we solve this problem without using regex this query replace only exact match string.

update employee set
employee_firstname = 
trim(REPLACE(concat(" ",employee_firstname," "),' jay ',' abc '))

Example:

emp_id employee_firstname

1 jay

2 jay ajay

3 jay

After executing query result:

emp_id employee_firstname

1 abc

2 abc ajay

3 abc

Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec

Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec, as I have ~/bin in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...

Launch it from the root of your project, where you can see src and target dirs.

The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)

$ mvnexec 
 1) org.jmeld.ui.JMeldComponent
 2) org.jmeld.ui.text.FileDocument
 3) org.jmeld.JMeld
 4) org.jmeld.util.UIDefaultsPrint
 5) org.jmeld.util.PrintProperties
 6) org.jmeld.util.file.DirectoryDiff
 7) org.jmeld.util.file.VersionControlDiff
 8) org.jmeld.vc.svn.InfoCmd
 9) org.jmeld.vc.svn.DiffCmd
10) org.jmeld.vc.svn.BlameCmd
11) org.jmeld.vc.svn.LogCmd
12) org.jmeld.vc.svn.CatCmd
13) org.jmeld.vc.svn.StatusCmd
14) org.jmeld.vc.git.StatusCmd
15) org.jmeld.vc.hg.StatusCmd
16) org.jmeld.vc.bzr.StatusCmd
17) org.jmeld.Main
18) org.apache.commons.jrcs.tools.JDiff
#? 

If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P)

By default it compiles project every run. but you can avoid that using mvnexec -B

It allows to search only in test classes -M or --no-main, or only in main classes -T or --no-test. also has a filter by name option -f <whatever>

Hope this could save you some time, for me it does.

Excerpt from this amazing blog:

Differences between concurrency and parallelism:

Concurrency is when two tasks can start, run, and complete in overlapping time periods. Parallelism is when tasks literally run at the same time, eg. on a multi-core processor.

Concurrency is the composition of independently executing processes, while parallelism is the simultaneous execution of (possibly related) computations.

Concurrency is about dealing with lots of things at once. Parallelism is about doing lots of things at once.

An application can be concurrent – but not parallel, which means that it processes more than one task at the same time, but no two tasks are executing at same time instant.

An application can be parallel – but not concurrent, which means that it processes multiple sub-tasks of a task in multi-core CPU at same time.

An application can be neither parallel – nor concurrent, which means that it processes all tasks one at a time, sequentially.

An application can be both parallel – and concurrent, which means that it processes multiple tasks concurrently in multi-core CPU at same time .

You need to use js get better height for body div

<html><body>
<div id="head" style="height:50px; width=100%; font-size:50px;">This is head</div>
<div id="body" style="height:700px; font-size:100px; white-space:pre-wrap;    overflow:scroll;">
This is body
T
h
i
s

i
s

b 
o
d
y
</div>
</body></html>

I would say that:

Object1.Equals(Object2)

would be what you're looking for. That's if you're looking to see if the objects are the same, which is what you seem to be asking.

If you want to check to see if all the child objects are the same, run them through a loop with the Equals() method.

By default Uint8Array, Uint16Array and Uint32Array classes keep zeros as its values, so you don't need any complex filling techniques, just do:

var ary = new Uint8Array(10);

all elements of array ary will be zeros by default.

In my environment, following code works. Although looks redundant at first glance, cookies[i].setValue(""); and cookies[i].setPath("/"); are necessary to clear the cookie properly.

private void eraseCookie(HttpServletRequest req, HttpServletResponse resp) {
    Cookie[] cookies = req.getCookies();
    if (cookies != null)
        for (Cookie cookie : cookies) {
            cookie.setValue("");
            cookie.setPath("/");
            cookie.setMaxAge(0);
            resp.addCookie(cookie);
        }
}

I don't think there's any need of writing this much big codes.

I've just installed angular-print bower package and all is set to go.

Just inject it in module and you're all set to go Use pre-built print directives & fun is that you can also hide some div if you don't want to print

Mine is working awesome .

Since version 2.1 of the Maven Dependency Plugin, there is a dependency:get goal for this purpose. To make sure you are using the right version of the plugin, you'll need to use the "fully qualified name":

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=http://download.java.net/maven/2/ \
    -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT

You did the right thing by checking from query plans. But I have 100% confidence in version 2. It is faster when the number off records are on the very high side.

My database has around 1,000,000 records and this is exactly the scenario where the query plan shows the difference between both the queries. Further, instead of using a where clause, if you use it in the join itself, it makes the query faster :
SELECT p.Name, s.OrderQty
FROM Product p
INNER JOIN (SELECT ProductID, OrderQty FROM SalesOrderDetail) s on p.ProductID = s.ProductID WHERE p.isactive = 1

The better version of this query is :

SELECT p.Name, s.OrderQty
FROM Product p
INNER JOIN (SELECT ProductID, OrderQty FROM SalesOrderDetail) s on p.ProductID = s.ProductID AND p.isactive = 1

(Assuming isactive is a field in product table which represents the active/inactive products).

You can get these parameter list in ControllerContext.RoutValues object as key-value pair.

You can store it in some variable and you make use of that variable in your logic.

You can make YouTube videos responsive with CSS. Wrap the iframe in a div with the class of "videowrapper" and apply the following styles:

.videowrapper {
    float: none;
    clear: both;
    width: 100%;
    position: relative;
    padding-bottom: 56.25%;
    padding-top: 25px;
    height: 0;
}
.videowrapper iframe {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

The .videowrapper div should be inside a responsive element. The padding on the .videowrapper is necessary to keep the video from collapsing. You may have to tweak the numbers depending upon your layout.

If X inherits from Y, that has two somewhat orthogonal effects:

1. Y will provide default functionality for X, so the code for X only has to include stuff which is different from Y.
2. Almost anyplace a Y would be expected, an X may be used instead.

Although inheritance provides for both features, it is not hard to imagine circumstances where either could be of use without the other. No .net language I know of has a direct way of implementing the first without the second, though one could obtain such functionality by defining a base class which is never used directly, and having one or more classes that inherit directly from it without adding anything new (such classes could share all their code, but would not be substitutable for each other). Any CLR-compliant language, however, will allow the use of interfaces which provide the second feature of interfaces (substitutability) without the first (member reuse).

Perl one-liner similar to @jonas's awk solution:

perl -ne 'print if ! $x{$_}++' file

This variation removes trailing whitespace before comparing:

perl -lne 's/\s*$//; print if ! $x{$_}++' file

This variation edits the file in-place:

perl -i -ne 'print if ! $x{$_}++' file

This variation edits the file in-place, and makes a backup file.bak

perl -i.bak -ne 'print if ! $x{$_}++' file

In SQL Server Import and Export Wizard you can adjust the source data types in the Advanced tab (these become the data types of the output if creating a new table, but otherwise are just used for handling the source data).

The data types are annoyingly different than those in MS SQL, instead of VARCHAR(255) it's DT_STR and the output column width can be set to 255. For VARCHAR(MAX) it's DT_TEXT.

So, on the Data Source selection, in the Advanced tab, change the data type of any offending columns from DT_STR to DT_TEXT (You can select multiple columns and change them all at once).

This one helped me for DataTables Version 1.10.4, because its new API

var oTable = $('#myTable').DataTable();    
$('#myInputTextField').keyup(function(){
   oTable.search( $(this).val() ).draw();
})

When I did just a remove the option remained in the ddl on the view, but was gone in the html (if u inspect the page)

$("#ddlSelectList option[value='2']").remove(); //removes the option with value = 2
$('#ddlSelectList').val('').trigger('chosen:updated'); //refreshes the drop down list

For me, I configured the build path to add JUnit 5 Library and also by adding the dependency

     <dependency> 
        <groupId>org.junit.platform</groupId> 
        <artifactId>junit-platform-launcher</artifactId> 
        <version>1.1.0</version> 
        <scope>test</scope> 
     </dependency>

seperately.

You can download IE Driver (both 32 and 64-bit) from Selenium official site: http://docs.seleniumhq.org/download/

32 bit Windows IE

64 bit Windows IE

IE Driver is also available in the following site:

http://selenium-release.storage.googleapis.com/index.html

Many people use both 2.X and 3.X python. You can use pip -V to show default pip version.
If you have many python versions, and you want to install some packages through different pip, I advise this way:

sudo python2.X -m pip install some-package==0.16

The above query returns the list of Object[]. So if you want to get the u.name and s.something from the list then you need to iterate and cast that values for the corresponding classes.
