Programs & Examples On #Builder

Its very simple

new AlertDialog.Builder(this).setView(input).setPositiveButton("ENTER",            
                        new DialogInterface.OnClickListener()                      
                        {   public void onClick(DialogInterface di,int id)     
                            {
                                output.setText(input.getText().toString());
                            }
                        }
                     )
        .create().show();

In case you wish to read the full program see here: Program to take input from user using dialog and output to screen

Your dialog should not be a "long-lived object that needs a context". The documentation is confusing. Basically if you do something like:

static Dialog sDialog;

(note the static)

Then in an activity somewhere you did

 sDialog = new Dialog(this);

You would likely be leaking the original activity during a rotation or similar that would destroy the activity. (Unless you clean up in onDestroy, but in that case you probably wouldn't make the Dialog object static)

For some data structures it would make sense to make them static and based off the application's context, but generally not for UI related things, like dialogs. So something like this:

Dialog mDialog;

...

mDialog = new Dialog(this);

Is fine and shouldn't leak the activity as mDialog would be freed with the activity since it's not static.

$users = User::all();
foreach($users->unique('column_name') as $user){
    code here..
}

You use it when you have lots of options to deal with. Think about things like jmock:

m.expects(once())
    .method("testMethod")
    .with(eq(1), eq(2))
    .returns("someResponse");

It feels a lot more natural and is...possible.

There's also xml building, string building and many other things. Imagine if java.util.Map had put as a builder. You could do stuff like this:

Map<String, Integer> m = new HashMap<String, Integer>()
    .put("a", 1)
    .put("b", 2)
    .put("c", 3);

You can use goto.

while ( ... ) {
   switch( ... ) {
     case ...:
         goto exit_loop;

   }
}
exit_loop: ;

I found that you can get this error if the returned object has getter only auto properties that are initialized in the constructor (with C# 6.0 syntax).

I believe this is due to WCF deserializing objects on the client side using a parameter-less constructor then setting the properties on the object. It needs to have a set available (it can be private) to fill the object, otherwise it'll fail.

I had the same issue caused by importing the internal version of 'takeUntil' instead of the operators Change

import { takeUntil } from 'rxjs/internal/operators/takeUntil';

to

import { takeUntil } from 'rxjs/operators';

This happen also for other operators

IF (EXISTS (SELECT * 
                 FROM INFORMATION_SCHEMA.TABLES 
                 WHERE  TABLE_NAME = 'd020915'))
BEGIN
  declare @result int
  set @result=1
  select @result as result
END

I had a similar issue, which made me write my own plugin for this. Have a look at jquery-quickfit (which is quite similar to Robert Koritnik's solution, which I really like).

In order to prevent the headline to span multiple lines, just add a css style of:

white-space:nowrap;

to the element.

After including jquery and quickfit in the header. You can trigger quickfit with:

$('h1').quickfit();

It meassures and calculates a size invariant meassure for each letter of the text to fit and uses this to calculate the next best font-size which fits the text into the container.

The calculations are cached, which makes it very fast when dealing having to fit multiple text or having to fit a text multiple times, like e.g., on window resize (there is almost no performance penalty on resize).

Demo for a similar situation as yours

Further documentation, examples and source code are on the project page.

Now you can use the Shared Project

Shared Project is a great way of sharing common code across multiple application We already have experienced with the Shared Project type in Visual Studio 2013 as part of Windows 8.1 Universal App Development, But with Visual Studio 2015, it is a Standalone New Project Template; and we can use it with other types of app like Console, Desktop, Phone, Store App etc.. This types of project is extremely helpful when we want to share a common code, logic as well as components across multiple applications with in single platform. This also allows accessing the platform-specific API ’s, assets etc.

for more info check this

import csv
with open('input.csv','r') as csvinput:
    with open('output.csv', 'w') as csvoutput:
        writer = csv.writer(csvoutput)

        for row in csv.reader(csvinput):
            if row[0] == "Name":
                writer.writerow(row+["Berry"])
            else:
                writer.writerow(row+[row[0]])

Maybe something like that is what you intended?

Also, csv stands for comma separated values. So, you kind of need commas to separate your values like this I think:

Name,Code
blackberry,1
wineberry,2
rasberry,1
blueberry,1
mulberry,2

I was trying to fix the issue for about an hour and just deiced to restart the server. Only to see the issue is fixed.

If you make changes to APP module and the issue remains the same, stop the server and try running the serve command again.

Using ionic 4 with angular 7

This should be rather a SuperUser question.

Right I have the exact same error inside MacOSX SourceTree, however, inside a iTerm2 terminal, things work just dandy.

However, the problem seemed to be that I've got two ssh-agents running ;(

The first being /usr/bin/ssh-agent (aka MacOSX's) and then also the HomeBrew installed /usr/local/bin/ssh-agent running.

Firing up a terminal from SourceTree, allowed me to see the differences in SSH_AUTH_SOCK, using lsof I found the two different ssh-agents and then I was able to load the keys (using ssh-add) into the system's default ssh-agent (ie. /usr/bin/ssh-agent), SourceTree was working again.

I found the answer on the web:

Dim fsT As Object
Set fsT = CreateObject("ADODB.Stream")
fsT.Type = 2 'Specify stream type - we want To save text/string data.
fsT.Charset = "utf-8" 'Specify charset For the source text data.
fsT.Open 'Open the stream And write binary data To the object
fsT.WriteText "special characters: äöüß"
fsT.SaveToFile sFileName, 2 'Save binary data To disk

Certainly not as I expected...

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

$elapsed = '2592000';
// Time in the past
$time_past = '2014-07-16 11:35:33';
$time_past = strtotime($time_past);

// Add a month to that time
$time_past = $time_past + $elapsed;

// Time NOW
$time_now = time();

// Check if its been a month since time past
if($time_past > $time_now){
    echo 'Hasnt been a month';    
}else{
    echo 'Been longer than a month';
}

First, HTML and PDF are not related although they were created around the same time. HTML is intended to convey higher level information such as paragraphs and tables. Although there are methods to control it, it is ultimately up to the browser to draw these higher level concepts. PDF is intended to convey documents and the documents must "look" the same wherever they are rendered.

In an HTML document you might have a paragraph that's 100% wide and depending on the width of your monitor it might take 2 lines or 10 lines and when you print it it might be 7 lines and when you look at it on your phone it might take 20 lines. A PDF file, however, must be independent of the rendering device, so regardless of your screen size it must always render exactly the same.

Because of the musts above, PDF doesn't support abstract things like "tables" or "paragraphs". There are three basic things that PDF supports: text, lines/shapes and images. (There are other things like annotations and movies but I'm trying to keep it simple here.) In a PDF you don't say "here's a paragraph, browser do your thing!". Instead you say, "draw this text at this exact X,Y location using this exact font and don't worry, I've previously calculated the width of the text so I know it will all fit on this line". You also don't say "here's a table" but instead you say "draw this text at this exact location and then draw a rectangle at this other exact location that I've previously calculated so I know it will appear to be around the text".

Second, iText and iTextSharp parse HTML and CSS. That's it. ASP.Net, MVC, Razor, Struts, Spring, etc, are all HTML frameworks but iText/iTextSharp is 100% unaware of them. Same with DataGridViews, Repeaters, Templates, Views, etc. which are all framework-specific abstractions. It is your responsibility to get the HTML from your choice of framework, iText won't help you. If you get an exception saying The document has no pages or you think that "iText isn't parsing my HTML" it is almost definite that you don't actually have HTML, you only think you do.

Third, the built-in class that's been around for years is the HTMLWorker however this has been replaced with XMLWorker (Java / .Net). Zero work is being done on HTMLWorker which doesn't support CSS files and has only limited support for the most basic CSS properties and actually breaks on certain tags. If you do not see the HTML attribute or CSS property and value in this file then it probably isn't supported by HTMLWorker. XMLWorker can be more complicated sometimes but those complications also make it more extensible.

Below is C# code that shows how to parse HTML tags into iText abstractions that get automatically added to the document that you are working on. C# and Java are very similar so it should be relatively easy to convert this. Example #1 uses the built-in HTMLWorker to parse the HTML string. Since only inline styles are supported the class="headline" gets ignored but everything else should actually work. Example #2 is the same as the first except it uses XMLWorker instead. Example #3 also parses the simple CSS example.

2017's update

There are good news for HTML-to-PDF demands. As this answer showed, the W3C standard css-break-3 will solve the problem... It is a Candidate Recommendation with plan to turn into definitive Recommendation this year, after tests.

As not-so-standard there are solutions, with plugins for C#, as showed by print-css.rocks.

If you have longer query and you like to use psql then put your query to a file and use the following command:

psql -d my_db_name -t -A -F";" -f input-file.sql -o output-file.csv

The simplest non recursive way is:

for d in */; do
    echo "$d"
done

The / at the end tells, use directories only.

There is no need for

• find
• awk
• ...

If you want to know the number of physical cores (not virtual hyperthreaded cores), here is a platform independent solution:

psutil.cpu_count(logical=False)

https://github.com/giampaolo/psutil/blob/master/INSTALL.rst

Note that the default value for logical is True, so if you do want to include hyperthreaded cores you can use:

psutil.cpu_count()

This will give the same number as os.cpu_count() and multiprocessing.cpu_count(), neither of which have the logical keyword argument.

@RequestMapping(
         value="person", 
         method=RequestMethod.POST,
         consumes="application/json",
         produces="application/json")
@ResponseBody
public List<String> savePerson(@RequestBody Person[] personArray) {
    List<String> response = new ArrayList<String>();
    for (Person person: personArray) {
        personService.save(person);
        response.add("Saved person: " + person.toString());
    }
    return response;
}

We can use Array as shown above.

Did you try

:set encoding=utf-8
:set fileencoding=utf-8

?

There are a few things to change in your edited version:

1. You've taken the suggestion of using document.myform['whichThing'] a bit too literally. Your form is named "aye", so the code to access the whichThing radio buttons should use that name: `document.aye['whichThing'].

2. There's no such thing as an action attribute for the <input> tag. Use onclick instead: <input name="Submit" type="submit" value="Update" onclick="handleClick();return false"/>

3. Obtaining and cancelling an Event object in a browser is a very involved process. It varies a lot by browser type and version. IE and Firefox handle these things very differently, so a simple event.preventDefault() won't work... in fact, the event variable probably won't even be defined because this is an onclick handler from a tag. This is why Stephen above is trying so hard to suggest a framework. I realize you want to know the mechanics, and I recommend google for that. In this case, as a simple workaround, use return false in the onclick tag as in number 2 above (or return false from the function as stephen suggested).

4. Because of #3, get rid of everything not the alert statement in your handler.

The code should now look like:

function handleClick()
      {
        alert("Favorite weird creature: "+getRadioButtonValue(document.aye['whichThing']));
      }
    </script>
  </head>
<body>
    <form name="aye">
      <input name="Submit"  type="submit" value="Update" onclick="handleClick();return false"/>
      Which of the following do you like best?
      <p><input type="radio" name="whichThing" value="slithy toves" />Slithy toves</p>
      <p><input type="radio" name="whichThing" value="borogoves" />Borogoves</p>
      <p><input type="radio" name="whichThing" value="mome raths" />Mome raths</p>
    </form>

The key to getting this to work is to tell sed to exclude what you don't want to be output as well as specifying what you do want.

string='This is a sample 123 text and some 987 numbers'
echo "$string" | sed -rn 's/[^[:digit:]]*([[:digit:]]+)[^[:digit:]]+([[:digit:]]+)[^[:digit:]]*/\1 \2/p'

This says:

• don't default to printing each line (-n)
• exclude zero or more non-digits
• include one or more digits
• exclude one or more non-digits
• include one or more digits
• exclude zero or more non-digits
• print the substitution (p)

In general, in sed you capture groups using parentheses and output what you capture using a back reference:

echo "foobarbaz" | sed 's/^foo\(.*\)baz$/\1/'

will output "bar". If you use -r (-E for OS X) for extended regex, you don't need to escape the parentheses:

echo "foobarbaz" | sed -r 's/^foo(.*)baz$/\1/'

There can be up to 9 capture groups and their back references. The back references are numbered in the order the groups appear, but they can be used in any order and can be repeated:

echo "foobarbaz" | sed -r 's/^foo(.*)b(.)z$/\2 \1 \2/'

outputs "a bar a".

If you have GNU grep (it may also work in BSD, including OS X):

echo "$string" | grep -Po '\d+'

or variations such as:

echo "$string" | grep -Po '(?<=\D )(\d+)'

The -P option enables Perl Compatible Regular Expressions. See man 3 pcrepattern or man 3 pcresyntax.

There's a bunch of functions to trim strings in go.

See them there : Trim

Here's an example, adapted from the documentation, removing leading and trailing white spaces :

fmt.Printf("[%q]", strings.Trim(" Achtung  ", " "))

Use Math.round(value) then after type cast it to integer.

float a = 8.61f;
int b = (int)Math.round(a);

You're looking for the /Y switch.

This is what worked for me in the end.

var showMenu = function(el, menu) {
    //get the position of the placeholder element  
    var pos = $(el).offset();    
    var eWidth = $(el).outerWidth();
    var mWidth = $(menu).outerWidth();
    var left = (pos.left + eWidth - mWidth) + "px";
    var top = 3+pos.top + "px";
    //show the menu directly over the placeholder  
    $(menu).css( { 
        position: 'absolute',
        zIndex: 5000,
        left: left, 
        top: top
    } );

    $(menu).hide().fadeIn();
};

Sometimes using row.getLastCellNum() gives you a higher value than what is actually filled in the file.
I used the method below to get the last column index that contains an actual value.

private int getLastFilledCellPosition(Row row) {
        int columnIndex = -1;

        for (int i = row.getLastCellNum() - 1; i >= 0; i--) {
            Cell cell = row.getCell(i);

            if (cell == null || CellType.BLANK.equals(cell.getCellType()) || StringUtils.isBlank(cell.getStringCellValue())) {
                continue;
            } else {
                columnIndex = cell.getColumnIndex();
                break;
            }
        }

        return columnIndex;
    }

Use:

$filelist = @(11, 1, 2)
$filelist | sort @{expression={$_[0]}} | 
  % {$newName = [string]([int]$($_[0]) + 1)}
  New-Item $newName -ItemType Directory

For a non-javascript solution, try putting a <button disabled>Submit</button> into your form, positioned before any other submit buttons/inputs. I suggest immediately after the <form> opening tag (and using CSS to hide it, accesskey='-1' to get it out of the tab sequence, etc)

AFAICT, user agents look for the first submit button when ENTER is hit in an input, and if that button is disabled will then stop looking for another.

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

Consequently, if the default button is disabled, the form is not submitted when such an implicit submission mechanism is used. (A button has no activation behavior when disabled.)

https://www.w3.org/TR/html5/forms.html#implicit-submission

However, I do know that Safari 10 MacOS misbehaves here, submitting the form even if the default button is disabled.

So, if you can assume javascript, insert <button onclick="return false;">Submit</button> instead. On ENTER, the onclick handler will get called, and since it returns false the submission process stops. Browsers I've tested this with won't even do the browser-validation thing (focussing the first invalid form control, displaying an error message, etc).

The package fBasics has a function colStdevs

 require('fBasics')
 set.seed(123)
 colStdevs(matrix(rnorm(1000, mean=10, sd=1), ncol=5))

Simply put it will define a setter and getter for the class.

Note that

attr_reader :v is equivalant to 
def v
  @v
end

attr_writer :v is equivalant to
def v=(value)
  @v=value
end

So

attr_accessor :v which means 
attr_reader :v; attr_writer :v 

are equivalant to define a setter and getter for the class.

If you want to retrieve multiple values of attributes from the source above, you can use findAll and a list comprehension to get everything you need:

import urllib
f = urllib.urlopen("http://58.68.130.147")
s = f.read()
f.close()

from BeautifulSoup import BeautifulStoneSoup
soup = BeautifulStoneSoup(s)

inputTags = soup.findAll(attrs={"name" : "stainfo"})
### You may be able to do findAll("input", attrs={"name" : "stainfo"})

output = [x["stainfo"] for x in inputTags]

print output
### This will print a list of the values.

["1","2","3","4"].forEach( function(item) { 
   const optionObj = document.createElement("option");
   optionObj.textContent = item;
   document.getElementById("myselect").appendChild(optionObj);
});

<body onbeforeunload="ConfirmClose()" onunload="HandleOnClose()">

var myclose = false;

function ConfirmClose()

    if (event.clientY < 0)
    {
        event.returnValue = 'You have closed the browser. Do you want to logout from your application?';
        setTimeout('myclose=false',10);
        myclose=true;
    }
}

function HandleOnClose()
{
    if (myclose==true) 
    {
        //the url of your logout page which invalidate session on logout 
        location.replace('/contextpath/j_spring_security_logout') ;
    }   
}

//This is working in IE7, if you are closing tab or browser with only one tab

That's assuming that str is non-null, and that if there are fewer than 2 characters, you just want the original string.

Read about Storage Engines.

MyISAM:

The MyISAM storage engine in MySQL.

• Simpler to design and create, thus better for beginners. No worries about the foreign relationships between tables.
• Faster than InnoDB on the whole as a result of the simpler structure thus much less costs of server resources. -- Mostly no longer true.
• Full-text indexing. -- InnoDB has it now
• Especially good for read-intensive (select) tables. -- Mostly no longer true.
• Disk footprint is 2x-3x less than InnoDB's. -- As of Version 5.7, this is perhaps the only real advantage of MyISAM.

InnoDB:

The InnoDB storage engine in MySQL.

• Support for transactions (giving you support for the ACID property).
• Row-level locking. Having a more fine grained locking-mechanism gives you higher concurrency compared to, for instance, MyISAM.
• Foreign key constraints. Allowing you to let the database ensure the integrity of the state of the database, and the relationships between tables.
• InnoDB is more resistant to table corruption than MyISAM.
• Support for large buffer pool for both data and indexes. MyISAM key buffer is only for indexes.
• MyISAM is stagnant; all future enhancements will be in InnoDB. This was made abundantly clear with the roll out of Version 8.0.

MyISAM Limitations:

• No foreign keys and cascading deletes/updates
• No transactional integrity (ACID compliance)
• No rollback abilities
• 4,284,867,296 row limit (2^32) -- This is old default. The configurable limit (for many versions) has been 2**56 bytes.
• Maximum of 64 indexes per table

InnoDB Limitations:

• No full text indexing (Below-5.6 mysql version)
• Cannot be compressed for fast, read-only (5.5.14 introduced ROW_FORMAT=COMPRESSED)
• You cannot repair an InnoDB table

G'day,

The declaration

static uint8_t l_matrix[10][20];

has set aside storage for 10 rows of 20 unit8_t locations, i.e. 200 uint8_t sized locations, with each element being found by calculating 20 x row + column.

So doesn't

uint8_t (*matrix_ptr)[20] = l_matrix;

give you what you need and point to the column zero element of the first row of the array?

Edit: Thinking about this a bit further, isn't an array name, by definition, a pointer? That is, the name of an array is a synonym for the location of the first element, i.e. l_matrix[0][0]?

Edit2: As mentioned by others, the comment space is a bit too small for further discussion. Anyway:

typedef uint8_t array_of_20_uint8_t[20];
array_of_20_uint8_t *matrix_ptr = l_matrix;

does not provide any allocation of storage for the array in question.

As mentioned above, and as defined by the standard, the statement:

static uint8_t l_matrix[10][20];

has set aside 200 sequential locations of type uint8_t.

Referring to l_matrix using statements of the form:

(*l_matrix + (20 * rowno) + colno)

will give you the contents of the colno'th element found in row rowno.

All pointer manipulations automatically take into account the size of the object pointed to. - K&R Section 5.4, p.103

This is also the case if any padding or byte alignment shifting is involved in the storage of the object at hand. The compiler will automatically adjust for these. By definition of the C ANSI standard.

HTH

cheers,

you can try like this...you can use Array.IndexOf() , if you want to know the position also

       string [] arr = {"One","Two","Three"};
       var target = "One";
       var results = Array.FindAll(arr, s => s.Equals(target));

You can call a reset function before appending. Something like this:

    function resetNewReviewBoardForm() {
    $("#Description").val('');
    $("#PersonName").text('');
    $("#members").empty(); //this one what worked in my case
    $("#EmailNotification").val('False');
}

Inside your function for the click action use

$( "#tabs" ).tabs({ active: # });

Where # is replaced by the tab index you want to select.

No, you must read the file, split it into separate queries and then execute them individually (or using the batch API of JDBC).

One of the reasons is that every database defines their own way to separate SQL statements (some use ;, others /, some allow both or even to define your own separator).

You could split on a word boundary with \b

As per latest Ansible Version 2.5, to check if a variable is defined and depending upon this if you want to run any task, use undefined keyword.

tasks:
    - shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
      when: foo is defined

    - fail: msg="Bailing out. this play requires 'bar'"
      when: bar is undefined

Ansible Documentation

AX is the 16 lower bits of EAX. AH is the 8 high bits of AX (i.e. the bits 8-15 of EAX) and AL is the least significant byte (bits 0-7) of EAX as well as AX.

Example (Hexadecimal digits):

EAX: 12 34 56 78
AX: 56 78
AH: 56
AL: 78

The sanctioned way of creating and using child processes is through the subprocess module.

import subprocess
pl = subprocess.Popen(['ps', '-U', '0'], stdout=subprocess.PIPE).communicate()[0]
print pl

The command is broken down into a python list of arguments so that it does not need to be run in a shell (By default the subprocess.Popen does not use any kind of a shell environment it just execs it). Because of this we cant simply supply 'ps -U 0' to Popen.

Below code should work for \n is required to be displayed on the string.

import string

our_str = 'The String is \\n, \\n and \\n!'
new_str = string.replace(our_str, '/\\n', '/\n', 1)
print(new_str)

For CentOS, run this: sudo yum install libXext libSM libXrender

If you want to respond to an event just one time, the following syntax should be really helpful:

 $('.myLink').bind('click', function() {
   //do some things

   $(this).unbind('click', arguments.callee); //unbind *just this handler*
 });

Using arguments.callee, we can ensure that the one specific anonymous-function handler is removed, and thus, have a single time handler for a given event. Hope this helps others.

While both reducebykey and groupbykey will produce the same answer, the reduceByKey example works much better on a large dataset. That's because Spark knows it can combine output with a common key on each partition before shuffling the data.

On the other hand, when calling groupByKey - all the key-value pairs are shuffled around. This is a lot of unnessary data to being transferred over the network.

for more detailed check this below link

https://databricks.gitbooks.io/databricks-spark-knowledge-base/content/best_practices/prefer_reducebykey_over_groupbykey.html

Using \b can yield surprising results. You would be better off figuring out what separates a word from its definition and incorporating that information into your pattern.

#!/usr/bin/perl

if ( $str =~ /\b(\Q$word\E)\b/ ) {

On Linux, I used the following params:

-Djavax.management.builder.initial= 
-Dcom.sun.management.jmxremote 
-Dcom.sun.management.jmxremote.port=9010 
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false

and also I edited /etc/hosts so that the hostname resolves to the host address (192.168.0.x) rather than the loopback address (127.0.0.1)

I don't know where you're running the site from on your computer, but you have an absolute file path to your C drive: C:\Users\VIRK\Desktop\66.jpg

Try this instead:

<img  src="[PATH_RELATIVE_TO_ROOT]/66.jpg" width="400" height="400" />

UPDATE:

I don't know what your $PROJECTHOME is set to. But say for example your site files are located at C:\Users\VIRK\MyWebsite. And let's say your images are in an 'images' folder within your main site, like so: C:\Users\VIRK\MyWebsite\images.

Then in your HTML you can simply reference the image within the images folder relative to the site, like so:

<img  src="images/66.jpg" width="400" height="400" />

Or, assuming you're hosting at the root of localhost and not within another virtual directory, you can do this (note the slash in the beginning):

<img  src="/images/66.jpg" width="400" height="400" />

I managed to get rid of this error (in my case using Ogre3D + Bullet) by changing the dependency libraries to the debug versions in Project Properties -> Linker -> Input -> Additional Dependencies (VC10).

I changed BulletCollision.lib to BulletCollision_debug.lib (for debug configuration) and it compiled.

Semantically what you are trying is invalid html, table element cannot have a div element as a direct child. What you can do is, get your div element inside a td element and than try to hide it

Thank you Phil for your solution; in case someone ever gets in the same situation as me, here is a (more complex) variant:

---
# this is just to avoid a call to |default on each iteration
- set_fact:
    postconf_d: {}

- name: 'get postfix default configuration'
  command: 'postconf -d'
  register: command

# the answer of the command give a list of lines such as:
# "key = value" or "key =" when the value is null
- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >
      {{
        postconf_d |
        combine(
          dict([ item.partition('=')[::2]|map('trim') ])
        )
  with_items: command.stdout_lines

This will give the following output (stripped for the example):

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": "hash:/etc/aliases, nis:mail.aliases",
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

Going even further, parse the lists in the 'value':

- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >-
      {% set key, val = item.partition('=')[::2]|map('trim') -%}
      {% if ',' in val -%}
        {% set val = val.split(',')|map('trim')|list -%}
      {% endif -%}
      {{ postfix_default_main_cf | combine({key: val}) }}
  with_items: command.stdout_lines
...

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": [
        "hash:/etc/aliases", 
        "nis:mail.aliases"
    ], 
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

A few things to notice:

• in this case it's needed to "trim" everything (using the >- in YAML and -%} in Jinja), otherwise you'll get an error like:

  FAILED! => {"failed": true, "msg": "|combine expects dictionaries, got u\"  {u'...
  

• obviously the {% if .. is far from bullet-proof

• in the postfix case, val.split(',')|map('trim')|list could have been simplified to val.split(', '), but I wanted to point out the fact you will need to |list otherwise you'll get an error like:

  "|combine expects dictionaries, got u\"{u'...': <generator object do_map at ...
  

Hope this can help.

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.

compiler could optimize memcpy, for example:

int x;
memcpy(&x, some_pointer, sizeof(int));

This memcpy may be optimized as: x = *(int*)some_pointer;

If (theChar >= '0' && theChar <='9') it's a digit. You get the idea.

To complete André's answer, an ant solution could be like the one described in Emacs, JDEE, Ant, and the Eclipse Java Compiler, as in:

      <javac
          srcdir="${src}"
          destdir="${build.dir}/classes"> 
        <compilerarg 
           compiler="org.eclipse.jdt.core.JDTCompilerAdapter" 
           line="-warn:+unused -Xemacs"/>
        <classpath refid="compile.classpath" />
      </javac>

The compilerarg element also allows you to pass in additional command line args to the eclipse compiler.

You can find a full ant script example here which would be invoked in a command line with:

java -cp C:/eclipse-SDK-3.4-win32/eclipse/plugins/org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar org.eclipse.core.launcher.Main -data "C:\Documents and Settings\Administrator\workspace" -application org.eclipse.ant.core.antRunner -buildfile build.xml -verbose

BUT all that involves ant, which is not what Keith is after.

For a batch compilation, please refer to Compiling Java code, especially the section "Using the batch compiler"

The batch compiler class is located in the JDT Core plug-in. The name of the class is org.eclipse.jdt.compiler.batch.BatchCompiler. It is packaged into plugins/org.eclipse.jdt.core_3.4.0..jar. Since 3.2, it is also available as a separate download. The name of the file is ecj.jar.
Since 3.3, this jar also contains the support for jsr199 (Compiler API) and the support for jsr269 (Annotation processing). In order to use the annotations processing support, a 1.6 VM is required.

Running the batch compiler From the command line would give

java -jar org.eclipse.jdt.core_3.4.0<qualifier>.jar -classpath rt.jar A.java

or:

java -jar ecj.jar -classpath rt.jar A.java

All java compilation options are detailed in that section as well.

The difference with the Visual Studio command line compilation feature is that Eclipse does not seem to directly read its .project and .classpath in a command-line argument. You have to report all information contained in the .project and .classpath in various command-line options in order to achieve the very same compilation result.

So, then short answer is: "yes, Eclipse kind of does." ;)

Use phpinfo() and search for Configuration File (php.ini) Path to see which config file path for php is used. PHP can have multiple config files depending on environment it's running. Usually, for console it's:

/etc/php5/cli/php.ini

and for php run by apache it's:

/etc/php5/apache2/php.ini

And then set error_reporting the way you need it:

http://www.phpknowhow.com/configuration/php-ini-error-settings/ http://www.zootemplate.com/news-updates/how-to-disable-notice-and-warning-in-phpini-file

Just to add to the answers, it also happens when your API response includes

<?php{username: 'Some'}

which could be a case when your backend is using PHP.

Mozilla recently released the awesome L20n or localization 2.0. In their own words L20n is

an open source, localization-specific scripting language used to process gender, plurals, conjugations, and most of the other quirky elements of natural language.

Their js implementation is on the github L20n repository.

It works fine for me on SQL Server 2017:

USE MSSQLTipsDemo 
GO
CREATE OR ALTER PROC CreateOrAlterDemo

In my case, the port 8080 was taken by some other service (Apache Airflow).

So I edit the HTTP port in this file:

sudo vi /etc/default/jenkins

And then started the service and it worked:

sudo service jenkins start

I was on Ubuntu 18.04 and installed openjdk-8

You can just check if the variable has a value or not. Meaning,

if( myVariable ) {
//mayVariable is not :
//null
//undefined
//NaN
//empty string ("")
//0
//false

}

If you do not know whether a variable exists (that means, if it was declared) you should check with the typeof operator. e.g.

if( typeof myVariable !== 'undefined' ) {
    // myVariable will get resolved and it is defined
}

1. Try this 2. and change the condition to "WINTER" and you will wonder:

public static void main(String[] args) {
  Season.add("Frühling");
  Season.add("Sommer");
  Season.add("Herbst");
  Season.add("WINTER");
  for (String s : Season) {
   if(!s.equals("Sommer")) {
    System.out.println(s);
    continue;
   }
   Season.remove("Frühling");
  }
 }

This is an obviously lacking, but easily added fix for AngularJS. Just write a quick directive to set the model value from the input field.

<input name="card[description]" value="Visa-4242" ng-model="card.description" ng-initial>

Here's my version:

var app = angular.module('forms', []);

app.directive('ngInitial', function() {
  return {
    restrict: 'A',
    controller: [
      '$scope', '$element', '$attrs', '$parse', function($scope, $element, $attrs, $parse) {
        var getter, setter, val;
        val = $attrs.ngInitial || $attrs.value;
        getter = $parse($attrs.ngModel);
        setter = getter.assign;
        setter($scope, val);
      }
    ]
  };
});

The answer is a simple PowerShell one-liner:

Get-WmiObject Win32_NetworkConnection | ft "RemoteName","LocalName" -A

If you only want to pull the UNC for one particular drive, add a where statement:

Get-WmiObject Win32_NetworkConnection | where -Property 'LocalName' -eq 'Z:'  | ft "RemoteName","LocalName" -A

The sexiest version by far is with format strings.

from datetime import datetime

print(f'{datetime.today():%Y-%m-%d}')

The {} syntax is deprecated as of PHP 5.3.0. Square brackets are recommended.

For Emacs users: C-x h (select the whole file) and then M-x reverse-region. Also works for only selecting parts or the lines and reverting those.

Try this:

int index = row.Table.Columns["ColumnName"].Ordinal;

You can't remove an element from the basic Java array. Take a look at various Collections and ArrayList instead.

Via SQL as per MSDN

SET IDENTITY_INSERT sometableWithIdentity ON

INSERT INTO sometableWithIdentity 
    (IdentityColumn, col2, col3, ...)
VALUES 
    (AnIdentityValue, col2value, col3value, ...)

SET IDENTITY_INSERT sometableWithIdentity OFF

The complete error message tells you exactly what is wrong...

Cannot insert explicit value for identity column in table 'sometableWithIdentity' when IDENTITY_INSERT is set to OFF.

Just from reading that i would have never understood that "$@" expands into a list of separate parameters. Whereas, "$*" is one parameter consisting of all the parameters added together.

If it still makes no sense do this.

Easily accomplished using a package.

Others have mentioned Moment. Moment is great but very large for a simple use like this, and unfortunately not modular so you have to import the whole package to use any of it.

I recommend using date-fns (https://date-fns.org/) (https://github.com/date-fns/date-fns). It is light-weight and modular, so you can import only the functions that you need.

In your case:

Install it: npm install date-fns --save

In your component:

import { format } from "date-fns";

var date = new Date("2016-01-04 10:34:23");

var formattedDate = format(date, "MMMM do, yyyy H:mma");

console.log(formattedDate);

Substitute the format string above "MMMM do, yyyy H:mma" with whatever format you require.

Update: v1 vs v2 format differences

v1 used Y for year and D for day, while v2 uses y and d. Format strings above have been updated for v2; the equivalent for v1 would be "MMMM Do, YYYY H:mma" (source: https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg/). Thanks @Red

The string representation of a DateTime can be parsed by the Time class.

The following test works in Chrome 16 (dev branch) on X86 and Chrome 15 on Mac OSX Lion

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

You can use sudo ip link delete to remove the interface.

I modified Bootstrap SASS (v3.3.5) based on Rukshan's answer

Add this in the end of the calc-grid-column mixin in mixins/_grid-framework.scss, right below the $type == offset if condition.

@if ($type == offset-right) {
      .col-#{$class}-offset-right-#{$index} {
          margin-right: percentage(($index / $grid-columns));
      }
  }

Modify the make-grid mixin in mixins/_grid-framework.scss to generate the offset-right classes.

// Create grid for specific class
@mixin make-grid($class) {
  @include float-grid-columns($class);
  @include loop-grid-columns($grid-columns, $class, width);
  @include loop-grid-columns($grid-columns, $class, pull);
  @include loop-grid-columns($grid-columns, $class, push);
  @include loop-grid-columns($grid-columns, $class, offset);
  @include loop-grid-columns($grid-columns, $class, offset-right);
}

You can then use the classes like col-sm-offset-right-2 and col-md-offset-right-1

You can make a jquery change listener on the input field and detect that user cancel or closed upload window by the value of the field.

here is an example:

//when upload button change
$('#upload_btn').change(function(){
    //get uploaded file
    var file = this.files[0];

    //if user choosed a file
    if(file){
        //upload file or perform your desired functiuonality
    }else{
        //user click cancel or close the upload window
    }
});

You need to use the alias directive for location /static:

server {

  index index.html;
  server_name test.example.com;

  root /web/test.example.com/www;

  location /static/ {
    alias /web/test.example.com/static/;
  }

}

The nginx wiki explains the difference between root and alias better than I can:

Note that it may look similar to the root directive at first sight, but the document root doesn't change, just the file system path used for the request. The location part of the request is dropped in the request Nginx issues.

Note that root and alias handle trailing slashes differently.

Google is going to shut the translate API down by the end of 2011, so you should be looking at the alternatives!

We can access super class elements by using super keyword

Consider we have two classes, Parent class and Child class, with different implementations of method foo. Now in child class if we want to call the method foo of parent class, we can do so by super.foo(); we can also access parent elements by super keyword.

    class parent {
    String str="I am parent";
    //method of parent Class
    public void foo() {
        System.out.println("Hello World " + str);
    }
}

class child extends parent {
    String str="I am child";
    // different foo implementation in child Class
    public void foo() {
        System.out.println("Hello World "+str);
    }

    // calling the foo method of parent class
    public void parentClassFoo(){
        super.foo();
    }

    // changing the value of str in parent class and calling the foo method of parent class
    public void parentClassFooStr(){
        super.str="parent string changed";
        super.foo();
    }
}


public class Main{
        public static void main(String args[]) {
            child obj = new child();
            obj.foo();
            obj.parentClassFoo();
            obj.parentClassFooStr();
        }
    }

What people seem to be missing is that if the hacker has access to the database he probably also has access to the php file that hashes the password and can likely just modify that to send him all the successful user name password combos. If he doesn't have access to the web directory he could always just pick a password hash it, and write that into the database. In other words the hash algorithm doesn't really matter as much as system security, and limiting login attempts also if you don't use SSL then the attacker can just listen in on the connection to get the information. Unless you need the algorithm to take a long time to compute (for your own purposes) then SHA-256 or SHA-512 with a user specific salt should be enough.

As an added security measure set up a script (bash, batch, python, etc) or program and give it an obscure name and have it check and see if login.php has changed (check date/time stamp) and send you an email if it has. Also should probably log all attempts at login with admin rights and log all failed attempts to log into the database and have the logs emailed to you.

format that can be reused as shell input

Edit february 2021: bash ${var@Q}

Under bash, you could store your variable content with Parameter Expansion's @ command for Parameter transformation:

${parameter@operator}
       Parameter transformation.  The expansion is either a transforma-
       tion of the value of parameter or  information  about  parameter
       itself,  depending on the value of operator.  Each operator is a
       single letter:

       Q      The expansion is a string that is the value of  parameter
              quoted in a format that can be reused as input.
...
       A      The  expansion  is  a string in the form of an assignment
              statement or declare command  that,  if  evaluated,  will
              recreate parameter with its attributes and value.

Sample:

$ var=$'Hello\nGood world.\n'
$ echo "$var"
Hello
Good world.

$ echo "${var@Q}"
$'Hello\nGood world.\n'

$ echo "${var@A}"
var=$'Hello\nGood world.\n'

Old answer

There is a special printf format directive (%q) built for this kind of request:

printf [-v var] format [arguments]

 %q     causes printf to output the corresponding argument
        in a format that can be reused as shell input.

Some samples:

read foo
Hello world
printf "%q\n" "$foo"
Hello\ world

printf "%q\n" $'Hello world!\n'
$'Hello world!\n'

This could be used through variables too:

printf -v var "%q" "$foo
"
echo "$var"
$'Hello world\n'

Quick check with all (128) ascii bytes:

Note that all bytes from 128 to 255 have to be escaped.

for i in {0..127} ;do
    printf -v var \\%o $i
    printf -v var $var
    printf -v res "%q" "$var"
    esc=E
    [ "$var" = "$res" ] && esc=-
    printf "%02X %s %-7s\n" $i $esc "$res"
done |
    column

This must render something like:

Where first field is hexa value of byte, second contain E if character need to be escaped and third field show escaped presentation of character.

Why ,?

You could see some characters that don't always need to be escaped, like ,, } and {.

So not always but sometime:

echo test 1, 2, 3 and 4,5.
test 1, 2, 3 and 4,5.

or

echo test { 1, 2, 3 }
test { 1, 2, 3 }

but care:

echo test{1,2,3}
test1 test2 test3

echo test\ {1,2,3}
test 1 test 2 test 3

echo test\ {\ 1,\ 2,\ 3\ }
test  1 test  2 test  3

echo test\ {\ 1\,\ 2,\ 3\ }
test  1, 2 test  3 

The Background property expects a Brush object, not a string. Change the type of the property to Brush and initialize it thus:

Background = new SolidColorBrush(Colors.Red);

just use this:

<script>
  var ctx = document.getElementById("myChart").getContext('2d');
  var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
      labels: ["1","2","3","4","5","6","7","8","9","10","11",],
      datasets: [{
        label: 'YOUR LABEL',
        backgroundColor: [
          "#566573",
          "#99a3a4",
          "#dc7633",
          "#f5b041",
          "#f7dc6f",
          "#82e0aa",
          "#73c6b6",
          "#5dade2",
          "#a569bd",
          "#ec7063",
          "#a5754a"
        ],
        data: [12, 19, 3, 17, 28, 24, 7, 2,4,14,6],            
      },]
    },
    //HERE COMES THE AXIS Y LABEL
    options : {
      scales: {
        yAxes: [{
          scaleLabel: {
            display: true,
            labelString: 'probability'
          }
        }]
      }
    }
  });
</script>

i have used this and solved my

-webkit-appearance:none;

Implement your adapter Filterable:

public class vJournalAdapter extends ArrayAdapter<JournalModel> implements Filterable{
private ArrayList<JournalModel> items;
private Context mContext;
....

then create your Filter class:

private class JournalFilter extends Filter{

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults result = new FilterResults();
        List<JournalModel> allJournals = getAllJournals();
        if(constraint == null || constraint.length() == 0){

            result.values = allJournals;
            result.count = allJournals.size();
        }else{
            ArrayList<JournalModel> filteredList = new ArrayList<JournalModel>();
            for(JournalModel j: allJournals){
                if(j.source.title.contains(constraint))
                    filteredList.add(j);
            }
            result.values = filteredList;
            result.count = filteredList.size();
        }

        return result;
    }
    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        if (results.count == 0) {
            notifyDataSetInvalidated();
        } else {
            items = (ArrayList<JournalModel>) results.values;
            notifyDataSetChanged();
        }
    }

}

this way, your adapter is Filterable, you can pass filter item to adapter's filter and do the work. I hope this will be helpful.

as per requested, here is the comment I gave earlier:

have a look at this:

• Vim integration to MonoDevelop for .net stuff at least..
• OmniCompletion

this link should help you if you want to use monodevelop on a MacOSX

Good luck and happy coding.

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;
        }
    }
}

This code is well-formed. You only have to pay attention that the definition of the template is visible at the point of instantiation. To quote the standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

I could be able to update the environment variable by using the following

string EnvPath = System.Environment.GetEnvironmentVariable("PATH", EnvironmentVariableTarget.Machine) ?? string.Empty;
if (!string.IsNullOrEmpty(EnvPath) && !EnvPath .EndsWith(";"))
    EnvPath = EnvPath + ';';
EnvPath = EnvPath + @"C:\Test";
Environment.SetEnvironmentVariable("PATH", EnvPath , EnvironmentVariableTarget.Machine);

"How do I do that? I explored PHPMyAdmin, and I can't find a "change engine" functionality."

In direct response to this part of your question, you can issue an ALTER TABLE tbl engine=InnoDB; and it'll recreate the table in the proper engine.

Here's my standard implementation. I like the labels to be self-descriptive.

Public Sub DoSomething()

    On Error GoTo Catch ' Try
    ' normal code here

    Exit Sub
Catch:

    'error code: you can get the specific error by checking Err.Number

End Sub

Or, with a Finally block:

Public Sub DoSomething()

    On Error GoTo Catch ' Try

    ' normal code here

    GoTo Finally
Catch:

    'error code

Finally:

    'cleanup code

End Sub

This is how to pass the struct by reference. This means that your function can access the struct outside of the function and modify its values. You do this by passing a pointer to the structure to the function.

#include <stdio.h>
/* card structure definition */
struct card
{
    int face; // define pointer face
}; // end structure card

typedef struct card Card ;

/* prototype */
void passByReference(Card *c) ;

int main(void)
{
    Card c ;
    c.face = 1 ;
    Card *cptr = &c ; // pointer to Card c

    printf("The value of c before function passing = %d\n", c.face);
    printf("The value of cptr before function = %d\n",cptr->face);

    passByReference(cptr);

    printf("The value of c after function passing = %d\n", c.face);

    return 0 ; // successfully ran program
}

void passByReference(Card *c)
{
    c->face = 4;
}

This is how you pass the struct by value so that your function receives a copy of the struct and cannot access the exterior structure to modify it. By exterior I mean outside the function.

#include <stdio.h>


/* global card structure definition */
struct card
{
    int face ; // define pointer face
};// end structure card

typedef struct card Card ;

/* function prototypes */
void passByValue(Card c);

int main(void)
{
    Card c ;
    c.face = 1;

    printf("c.face before passByValue() = %d\n", c.face);

    passByValue(c);

    printf("c.face after passByValue() = %d\n",c.face);
    printf("As you can see the value of c did not change\n");
    printf("\nand the Card c inside the function has been destroyed"
        "\n(no longer in memory)");
}


void passByValue(Card c)
{
    c.face = 5;
}

Gotcha!

You have to use RegisterStartupScript instead of RegisterClientScriptBlock

Here My Example.

MasterPage:

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace prueba
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            ClientScript.RegisterStartupScript(this.GetType(), "js", "confirmCallBack();", true);

        }
    }
}

I think you can use "a string.Contains("str") for this.

it will search in a string to a patern, and result true is founded and false if not.

Based on @carlosfigueira 's answer, I looked further into WebClient's methods and found UploadValues, which is exactly what I want:

Using client As New Net.WebClient
    Dim reqparm As New Specialized.NameValueCollection
    reqparm.Add("param1", "somevalue")
    reqparm.Add("param2", "othervalue")
    Dim responsebytes = client.UploadValues(someurl, "POST", reqparm)
    Dim responsebody = (New Text.UTF8Encoding).GetString(responsebytes)
End Using

The key part is this:

client.UploadValues(someurl, "POST", reqparm)

It sends whatever verb I type in, and it also helps me create a properly url encoded form data, I just have to supply the parameters as a namevaluecollection.

str.split() without any arguments splits on runs of whitespace characters:

>>> s = 'I am having a very nice day.'
>>> 
>>> len(s.split())
7

From the linked documentation:

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.

there are some syntax errors to your program heres a working code;

#include<stdio.h>
int main()
{
int a,b;
printf("enter any two number\n");
scanf("%d%d",&a,&b);
if (a%b==0){
printf("this is  multiple number");
}
else if (b%a==0){
printf("this is multiple number");
}
else{
printf("this is not multiple number");
return 0;
}

}

You can simulate this problem with a syntax mistake, however, %matplotlib inline won't resolve the issue.

First an example of the right way to create a plot. Everything works as expected with the imports and magic that eNord9 supplied.

df_randNumbers1 = pd.DataFrame(np.random.randint(0,100,size=(100, 6)), columns=list('ABCDEF'))

df_randNumbers1.ix[:,["A","B"]].plot.kde()

However, by leaving the () off the end of the plot type you receive a somewhat ambiguous non-error.

Erronious code:

df_randNumbers1.ix[:,["A","B"]].plot.kde

Example error:

<bound method FramePlotMethods.kde of <pandas.tools.plotting.FramePlotMethods object at 0x000001DDAF029588>>

Other than this one line message, there is no stack trace or other obvious reason to think you made a syntax error. The plot doesn't print.

Why reinvent the wheel. Just use the STL list container.

#include <list>

// in some function, you now do...
std::list<int> mylist; // integer list

More information...

If you are working with a Servlet and if the servlet context is available to you, you can use :

getServletContext().getMimeType( fileName );

I would like to compliment Ram Narasimhans answer with some tips I found on an Excel blog

Non-uniformly distributed data can be plotted in excel in

• X Y (Scatter Plots)
• Linear plots with Date axis
  • These don't take time into account, only days.
  • This method is quite cumbersome as it requires translating your time units to days, months, or years.. then change the axis labels... Not Recommended

Just like Ram Narasimhan suggested, to have the points centered you will want the mid point but you don't need to move to a numeric format, you can stay in the time format.

1- Add the center point to your data series

+---------------+-------+------+
|    Time       | Time  | Freq |
+---------------+-------+------+
| 08:00 - 09:00 | 08:30 |  12  |
| 09:00 - 10:00 | 09:30 |  13  |
| 10:00 - 11:00 | 10:30 |  10  |
| 13:00 - 14:00 | 13:30 |   5  |
| 14:00 - 15:00 | 14:30 |  14  |
+---------------+-------+------+

2- Create a Scatter Plot

3- Excel allows you to specify time values for the axis options. Time values are a parts per 1 of a 24-hour day. Therefore if we want to 08:00 to 15:00, then we Set the Axis options to:

• Minimum : Fix : 0.33333
• Maximum : Fix : 0.625
• Major unit : Fix : 0.041667

Alternative Display:

Make the points turn into columns:

To be able to represent these points as bars instead of just point we need to draw disjoint lines. Here is a way to go about getting this type of chart.

1- You're going to need to add several rows where we draw the line and disjoint the data

+-------+------+
| Time  | Freq |
+-------+------+
| 08:30 |   0  |
| 08:30 |  12  |
|       |      |
| 09:30 |   0  |
| 09:30 |  13  |
|       |      |
| 10:30 |   0  |
| 10:30 |  10  |
|       |      |
| 13:30 |   0  |
| 13:30 |   5  |
|       |      |
| 14:30 |   0  |
| 14:30 |  14  |
+-------+------+

2- Plot an X Y (Scatter) Chart with Lines.

3- Now you can tweak the data series to have a fatter line, no markers, etc.. to get a bar/column type chart with non-uniformly distributed data.

int main () //start of main fcn
{

    int values[ 20 ]; //delcares array and how many elements
    int small,big; //declares integer
     for ( int i = 0; i < 20; i++ ) //counts to 20 and prompts user for value and stores it
    {
        cout << "Enter value " << i << ": ";
        cin >> values[i];
    }
    big=small=values[0]; //assigns element to be highest or lowest value
    for (int i = 0; i < 20; i++) //works out bigggest number
    {
        if(values[i]>big) //compare biggest value with current element
        {
            big=values[i];
        }
         if(values[i]<small) //compares smallest value with current element
        {
            small=values[i];
        }
    }
     cout << "The biggest number is " << big << endl; //prints outs biggest no
    cout << "The smallest number is " << small << endl; //prints out smalles no
}

Based on the stacktrace, an intuit class com.intuit.ipp.aggcat.util.SAML2AssertionGenerator needs a saml jar on the classpath.

A saml class org.opensaml.xml.XMLConfigurator needs on it's turn log4j, which is inside the WAR but cannot find it.

One explanation for this is that the class XMLConfigurator that needs log4j was found not inside the WAR but on a downstream classloader. could a saml jar be missing from the WAR?

The class XMLConfigurator that needs log4j cannot find it at the level of the classloader that loaded it, and the log4j version on the WAR is not visible on that particular classloader.

In order to troubleshoot this, a way is to add this before the oauth call:

System.out.println("all versions of log4j Logger: " + getClass().getClassLoader().getResources("org/apache/log4j/Logger.class") );

System.out.println("all versions of XMLConfigurator: " + getClass().getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );

System.out.println("all versions of XMLConfigurator visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassLoader().getResources("org/opensaml/xml/XMLConfigurator.class") );

System.out.println("all versions of log4j visible from the classloader of the OAuthAuthorizer class: " + OAuthAuthorizer.class.getClassloader().getResources("org/apache/log4j/Logger.class") );

Also if you are using Java 7, have a look at jHades, it's a tool I made to help troubleshooting these type of problems.

In order to see what is going on, could you post the results of the classpath queries above, for which container is this happening, tomcat, jetty? It would be better to put the full stacktrace with all the caused by's in pastebin, just in case.

All the above works, and here is another way if you just want to number of days/time back rather a entering date

select * from *table_name* where *datetime_column* BETWEEN DATE_SUB(NOW(), INTERVAL 30 DAY)  AND NOW() 

According to Documentation

git diff Shows changes between the working tree and the index or a tree, changes between the index and a tree, changes between two trees, changes resulting from a merge, changes between two blob objects, or changes between two files on disk.

In git diff - There's a significant difference between two dots .. and 3 dots ... in the way we compare branches or pull requests in our repository. I'll give you an easy example which demonstrates it easily.

Example: Let's assume we're checking out new branch from master and pushing some code in.

  G---H---I feature (Branch)
 /
A---B---C---D master (Branch)

• Two dots - If we want to show the diffs between all changes happened in the current time on both sides, We would use the git diff origin/master..feature or just git diff origin/master
  ,output: ( H, I against A, B, C, D )

• Three dots - If we want to show the diffs between the last common ancestor (A), aka the check point we started our new branch ,we use git diff origin/master...feature,output: (H, I against A ).

• I'd rather use the 3 dots in most circumstances.

This can also happen in safari if you try a selector with a missing ], for example

$('select[name="something"')

but interestingly, this same jquery selector with a missing bracket will work in chrome.

The accepted answer is correct, but not complete. In order for Select All to be the default option, the Available Values dataset must contain at least 2 columns: value and label. They can return the same data, but their names have to be different. The Default Values dataset will then use value column and then Select All will be the default value. If the dataset returns only 1 column, only the last record's value will be selected in the drop down of the parameter.

In the end the same rules as for css apply.

So I think this reference could be of some valuable use.

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

Change your meta tag to the one below and use placeholder attribute inside your HTML input tag.

<meta http-equiv="X-UA-Compatible" content="IE=edge" />_x000D_
<input type="text" placeholder="Placeholder text" />?

I've used Beej's Guide to Network Programming in the past. It's in C, not C++, but the examples are good. Go directly to section 6 for the simple client and server example programs.

Ok, yup you use the timeout command to sleep. But to do the whole process silently, it's not possible with cmd/batch. One of the ways is to create a VBScript that will run the Batch File without opening/showing any window. And here is the script:

Set WshShell = CreateObject("WScript.Shell")
WshShell.Run chr(34) & "PATH OF BATCH FILE WITH QUOTATION MARKS" & Chr(34), 0
Set WshShell = Nothing

Copy and paste the above code on notepad and save it as Anyname.**vbs ** An example of the *"PATH OF BATCH FILE WITH QUOTATION MARKS" * might be: "C:\ExampleFolder\MyBatchFile.bat"

Another way to solve this would be with a LEFT JOIN, which could be more efficient. I'll first start with an example that considers only the date field, as probably it is more common to store date + time in one datetime column, and I also want to keep the query simple so it's easier to understand.

So, with this particular example, if you want to show the oldest record based on the date column, and assuming that your table name is called people you can use the following query:

SELECT p.* FROM people p
LEFT JOIN people p2 ON p.name = p2.name AND p.date > p2.date
WHERE p2.date is NULL
GROUP BY p.name

What the LEFT JOIN does, is when the p.date column is at its minimum value, there will be no p2.date with a smaller value on the left join and therefore the corresponding p2.date will be NULL. So, by adding WHERE p2.date is NULL, we make sure to show only the records with the oldest date.

And similarly, if you want to show the newest record instead, you can just change the comparison operator in the LEFT JOIN:

SELECT p.* FROM people p
LEFT JOIN people p2 ON p.name = p2.name AND p.date < p2.date
WHERE p2.date is NULL
GROUP BY p.name

Now, for this particular example where date+time are separate columns, you would need to add them in some way if you want to query based on the datetime of two columns combined, for example:

SELECT p.* FROM people p
LEFT JOIN people p2 ON p.name = p2.name AND p.date + INTERVAL TIME_TO_SEC(p.time) SECOND > p2.date + INTERVAL TIME_TO_SEC(p2.time) SECOND
WHERE p2.date is NULL
GROUP BY p.name

You can read more about this (and also see some other ways to accomplish this) on the The Rows Holding the Group-wise Maximum of a Certain Column page.

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

To answer your updated question you can do

String[] lines = ("Name =              Bob\n" +
        "Age =               27\n" +
        "Occupation =        Student\n" +
        "Status =            Single").split("\n");

for (String line : lines) {
    String[] parts = line.split(" = +");
    System.out.printf("%-19s %s%n", parts[0] + " =", parts[1]);
}

prints

Name =              Bob
Age =               27
Occupation =        Student
Status =            Single

I have solved this problem, very easily.

• Just reboot the computer ( it refreshes everything by itself ).

I hope this helps..

Run top then press OpEnter. Now processes should be sorted by their swap usage.

Here is an update as my original answer does not provide an exact answer to the problem as pointed out in the comments. From the htop FAQ:

It is not possible to get the exact size of used swap space of a process. Top fakes this information by making SWAP = VIRT - RES, but that is not a good metric, because other stuff such as video memory counts on VIRT as well (for example: top says my X process is using 81M of swap, but it also reports my system as a whole is using only 2M of swap. Therefore, I will not add a similar Swap column to htop because I don't know a reliable way to get this information (actually, I don't think it's possible to get an exact number, because of shared pages).

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

This gives me the same error as trying to split the list up and zip it. ValueError: dictionary update sequence element #0 has length 1916; 2 is required

THAT is your actual question.

The answer is that the elements of your list are not what you think they are. If you type myList[0] you will find that the first element of your list is not a two-tuple, e.g. ('A', 1), but rather a 1916-length iterable.

Once you actually have a list in the form you stated in your original question (myList = [('A',1),('B',2),...]), all you need to do is dict(myList).

Assuming your "states" collection is like:

{"name" : "Spain", "cities" : [ { "name" : "Madrid" }, { "name" : null } ] }
{"name" : "France" }

The query to find states with null cities would be:

db.states.find({"cities.name" : {"$eq" : null, "$exists" : true}});

It is a common mistake to query for nulls as:

db.states.find({"cities.name" : null});

because this query will return all documents lacking the key (in our example it will return Spain and France). So, unless you are sure the key is always present you must check that the key exists as in the first query.

I think you can simple call like this, this will give you result value.

this.$route.query.page

Look image $route is object in Vue Instance and you can access with this keyword and next you can select object properties like above one :

Have a look Vue-router document for selecting queries value :

Vue Router Object

Just use CASCADE

TRUNCATE "products" RESTART IDENTITY CASCADE;

But be ready for cascade deletes )

in your css file add this....

a:hover {
 cursor:pointer;
}

if you don't have a css file, add this to the HEAD of your HTML page

<style type="text/css">
 a:hover {
  cursor:pointer;
 }
</style>

also you can use the href="" attribute by returning false at the end of your javascript.

<a href="" onclick="doSomething(); return false;">a link</a>

this is good for many reasons. SEO or if people don't have javascript, the href="" will work. e.g.

<a href="nojavascriptpage.html" onclick="doSomething(); return false;">a link</a>

@see http://www.alistapart.com/articles/behavioralseparation

Edit: Worth noting @BalusC's answer where he mentions :hover is not necessary for the OP's use case. Although other style can be add with the :hover selector.

According to the Mysql UPDATE Syntax linked by @CheekySoft, it says right at the bottom.

Currently, you cannot update a table and select from the same table in a subquery.

I guess you are deleting from store_category while still selecting from it in the union.

Sorry, I solved my problem with the code above:

$("#captureImage").live("change", function() {
    if($("#captureImage:checked").val() !== undefined) {
        navigator.device.capture.captureImage(function(mediaFiles) {
            console.log("works");
        }, function(exception) {
            $("#captureImage").removeAttr('checked').checkboxradio('refresh');
            _callback.error(exception);
        }, {});
    }
});

To make it more generic of keeping both columns in df1 and df2:

import pyspark.sql.functions as F

# Keep all columns in either df1 or df2
def outter_union(df1, df2):

    # Add missing columns to df1
    left_df = df1
    for column in set(df2.columns) - set(df1.columns):
        left_df = left_df.withColumn(column, F.lit(None))

    # Add missing columns to df2
    right_df = df2
    for column in set(df1.columns) - set(df2.columns):
        right_df = right_df.withColumn(column, F.lit(None))

    # Make sure columns are ordered the same
    return left_df.union(right_df.select(left_df.columns))

Find repoName from the url, and then checkout to the specified directory.

String url = 'https://github.com/foo/bar.git';
String[] res = url.split('/');
String repoName = res[res.length-1];
if (repoName.endsWith('.git')) repoName=repoName.substring(0, repoName.length()-4);

checkout([
  $class: 'GitSCM', 
  branches: [[name: 'refs/heads/'+env.BRANCH_NAME]],
  doGenerateSubmoduleConfigurations: false,
  extensions: [
    [$class: 'RelativeTargetDirectory', relativeTargetDir: repoName],
    [$class: 'GitLFSPull'],
    [$class: 'CheckoutOption', timeout: 20],
    [$class: 'CloneOption',
        depth: 3,
        noTags: false,
        reference: '/other/optional/local/reference/clone',
        shallow: true,
        timeout: 120],
    [$class: 'SubmoduleOption', depth: 5, disableSubmodules: false, parentCredentials: true, recursiveSubmodules: true, reference: '', shallow: true, trackingSubmodules: true]
  ],
  submoduleCfg: [],
  userRemoteConfigs: [
    [credentialsId: 'foobar',
    url: url]
  ]
])

this is the DOM element on which the event was hooked. this.id is its ID. No need to wrap it in a jQuery instance to get it, the id property reflects the attribute reliably on all browsers.

$("select").change(function() {    
    alert("Changed: " + this.id);
}

Live example

You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event object's target property:

$("#container").change(function(event) {
    alert("Field " + event.target.id + " changed");
});

Live example

(jQuery ensures that the change event bubbles, even on IE where it doesn't natively.)

Boost has regex in it.

That should fill the bill

For the low-level x86 specific solution use the x86 TEST opcode.

Your compiler should turn _bittest into this though...

Calling conventions defines how parameters are passed in the registers when calling or being called by other program. And the best source of these convention is in the form of ABI standards defined for each these hardware. For ease of compilation, the same ABI is also used by userspace and kernel program. Linux/Freebsd follow the same ABI for x86-64 and another set for 32-bit. But x86-64 ABI for Windows is different from Linux/FreeBSD. And generally ABI does not differentiate system call vs normal "functions calls". Ie, here is a particular example of x86_64 calling conventions and it is the same for both Linux userspace and kernel: http://eli.thegreenplace.net/2011/09/06/stack-frame-layout-on-x86-64/ (note the sequence a,b,c,d,e,f of parameters):

Performance is one of the reasons for these ABI (eg, passing parameters via registers instead of saving into memory stacks)

For ARM there is various ABI:

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.subset.swdev.abi/index.html

https://developer.apple.com/library/ios/documentation/Xcode/Conceptual/iPhoneOSABIReference/iPhoneOSABIReference.pdf

ARM64 convention:

http://infocenter.arm.com/help/topic/com.arm.doc.ihi0055b/IHI0055B_aapcs64.pdf

For Linux on PowerPC:

http://refspecs.freestandards.org/elf/elfspec_ppc.pdf

http://www.0x04.net/doc/elf/psABI-ppc64.pdf

And for embedded there is the PPC EABI:

http://www.freescale.com/files/32bit/doc/app_note/PPCEABI.pdf

This document is good overview of all the different conventions:

http://www.agner.org/optimize/calling_conventions.pdf

You have an array, convert it to an object, something like:

data: [{"id": 3636, "is_default": true, "name": "Unit", "quantity": 1, "stock": "100000.00", "unit_cost": "0"}, {"id": 4592, "is_default": false, "name": "Bundle", "quantity": 5, "stock": "100000.00", "unit_cost": "0"}]

The C compiler can glue adjacent string literals into one, like

printf("foo: %s "
       "bar: %d", foo, bar);

The preprocessor can use a backslash as a last character of the line, not counting CR (or CR/LF, if you are from Windowsland):

printf("foo %s \
bar: %d", foo, bar);

MSDN: Configuration Manager.AppSettings

if (ConfigurationManager.AppSettings[name] != null)
{
// Now do your magic..
}

or

string s = ConfigurationManager.AppSettings["myKey"];
if (!String.IsNullOrEmpty(s))
{
    // Key exists
}
else
{
    // Key doesn't exist
}

Generally the reason why the "instanceof" operator is frowned upon in a case like that (where the instanceof is checking for subclasses of this base class) is because what you should be doing is moving the operations into a method and overridding it for the appropriate subclasses. For instance, if you have:

if (o instanceof Class1)
   doThis();
else if (o instanceof Class2)
   doThat();
//...

You can replace that with

o.doEverything();

and then have the implementation of "doEverything()" in Class1 call "doThis()", and in Class2 call "doThat()", and so on.

I had all my settings covered in the accepted answer. The problem I had was that I was trying to update the Entity Framework entity type "Task" like:

public IHttpActionResult Post(Task task)

What worked for me was to create my own entity "DTOTask" like:

public IHttpActionResult Post(DTOTask task)

Excel has a very powerful feature providing for a dropdown select list in a cell, reflecting data from a named region. It'a a very easy configuration, once you have done it before. Two steps are to follow:

Create a named region,
Setup the dropdown in a cell.

There is a detailed explanation of the process HERE.

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

I've written a simple class for rotating image. All you've to do is input image and angle of rotation in Degree. Angle must be between -90 and +90.

public class ImageRotator
{
    private readonly Bitmap image;
    public Image OriginalImage
    {
        get { return image; }
    }


    private ImageRotator(Bitmap image)
    {
        this.image = image;
    }


    private double GetRadian(double degree)
    {
        return degree * Math.PI / (double)180;
    }


    private Size CalculateSize(double angle)
    {
        double radAngle = GetRadian(angle);
        int width = (int)(image.Width * Math.Cos(radAngle) + image.Height * Math.Sin(radAngle));
        int height = (int)(image.Height * Math.Cos(radAngle) + image.Width * Math.Sin(radAngle));
        return new Size(width, height);
    }

    private PointF GetTopCoordinate(double radAngle)
    {
        Bitmap image = CurrentlyViewedMappedImage.BitmapImage;
        double topX = 0;
        double topY = 0;

        if (radAngle > 0)
        {
            topX = image.Height * Math.Sin(radAngle);
        }
        if (radAngle < 0)
        {
            topY = image.Width * Math.Sin(-radAngle);
        }
        return new PointF((float)topX, (float)topY);

        g.TranslateTransform(topPoint.X, topPoint.Y);
        g.RotateTransform(GetDegree(radAngle));
        g.DrawImage(image, new RectangleF(0, 0, size.Width, size.Height));

        g.Dispose();

You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.

I think what you were looking for in your Range was this:

Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete

Just change the column letters to match your needs.

A simpler way is:

$('head').append('<script type="text/javascript" src="your.js"></script>');

You can also use this form to load css.

In bash echo without quotes remove carriage returns, tabs and multiple spaces

echo $(cat file)

The solutions posted here did not work well for me, so I did a mixture of the ones of this question and the following question: Is it possible to create multi-level ordered list in HTML?

/* Numbered lists like 1, 1.1, 2.2.1... */
ol li {display:block;} /* hide original list counter */
ol > li:first-child {counter-reset: item;} /* reset counter */
ol > li {counter-increment: item; position: relative;} /* increment counter */
ol > li:before {content:counters(item, ".") ". "; position: absolute; margin-right: 100%; right: 10px;} /* print counter */

Result:

Note: the screenshot, if you wish to see the source code or whatever is from this post: http://estiloasertivo.blogspot.com.es/2014/08/introduccion-running-lean-y-lean.html

You can use Explicit wait or Fluent Wait

Example of Explicit Wait -

WebDriverWait wait = new WebDriverWait(WebDriverRefrence,20);
WebElement aboutMe;
aboutMe= wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("about_me")));     

Example of Fluent Wait -

Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)                            
.withTimeout(20, TimeUnit.SECONDS)          
.pollingEvery(5, TimeUnit.SECONDS)          
.ignoring(NoSuchElementException.class);    

  WebElement aboutMe= wait.until(new Function<WebDriver, WebElement>() {       
public WebElement apply(WebDriver driver) { 
return driver.findElement(By.id("about_me"));     
 }  
});

jQuery has a utility function for this:

$.inArray(value, array)

Returns index of value in array. Returns -1 if array does not contain value.

See also How do I check if an array includes an object in JavaScript?

I just got this error and it was caused by a duplicate static content MIME type in the web.config

This error was being returned only on static files - eg images, css, js files were all saying this error (text by itself, no other html or text in the response).

The way to debug this is to look in web config under static content. Here we have a json file extension loaded. This was required on IIS7 but will kill the app if used on IIS8 because json is now pre-loaded at the server level.

    <staticContent>
        <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="30.00:00:00" />
        <mimeMap fileExtension=".json" mimeType="application/json" />
    </staticContent>

So solution is to remove any of these mimeType entries one at a time to confirm which are needed and which kill your app!

Update

Actually the best solution was provided by a commenter here. You can remove and then add, which will always work regardless of whether it is already defined or not. Like this:

<remove fileExtension=".json" /> 
<mimeMap fileExtension=".json" mimeType="application/json" />

This is the modern c++ approach using a template function which is working for float, double, long, int and short (but not for long long, and long double because of the used double values).

#include <cmath>
#include <iostream>

template<typename T>
T roundMultiple( T value, T multiple )
{
    if (multiple == 0) return value;
    return static_cast<T>(std::round(static_cast<double>(value)/static_cast<double>(multiple))*static_cast<double>(multiple));
}

int main()
{
    std::cout << roundMultiple(39298.0, 100.0) << std::endl;
    std::cout << roundMultiple(20930.0f, 1000.0f) << std::endl;
    std::cout << roundMultiple(287399, 10) << std::endl;
}

But you can easily add support for long long and long double with template specialisation as shown below:

template<>
long double roundMultiple<long double>( long double value, long double multiple)
{
    if (multiple == 0.0l) return value;
    return std::round(value/multiple)*multiple;
}

template<>
long long roundMultiple<long long>( long long value, long long multiple)
{
    if (multiple == 0.0l) return value;
    return static_cast<long long>(std::round(static_cast<long double>(value)/static_cast<long double>(multiple))*static_cast<long double>(multiple));
}

To create functions to round up, use std::ceil and to always round down use std::floor. My example from above is rounding using std::round.

Create the "round up" or better known as "round ceiling" template function as shown below:

template<typename T>
T roundCeilMultiple( T value, T multiple )
{
    if (multiple == 0) return value;
    return static_cast<T>(std::ceil(static_cast<double>(value)/static_cast<double>(multiple))*static_cast<double>(multiple));
}

Create the "round down" or better known as "round floor" template function as shown below:

template<typename T>
T roundFloorMultiple( T value, T multiple )
{
    if (multiple == 0) return value;
    return static_cast<T>(std::floor(static_cast<double>(value)/static_cast<double>(multiple))*static_cast<double>(multiple));
}

TextView text = new TextView(context);
text.setTextColor(Color.parseColor("any hex value of a color"));

Above code is working on my side. Here text is a TextView on which color is needed to be set.

Here is the JSfiddle Demo

I changed your HTML and give your input textfield an id of value. I removed the passed param for your verifyorder function, and instead grab the content of your textfield by using document.getElementById(); then i convert the str into value with +order so you can check if it's greater than zero:

<input type="text" maxlength="3" name="value" id='value' />
<input type="button" value="submit" onclick="verifyorder()" />
</p>
<p id="error"></p>
<p id="detspace"></p> 

function verifyorder() {
        var order = document.getElementById('value').value;
        if (+order > 0) {
            alert(+order);
            return true;
        }
        else {
            alert("Sorry, you need to enter a positive integer value, try again");
            document.getElementById('error').innerHTML = "Sorry, you need to enter a positive integer value, try again";
        }
    }

You can use the beforeSend callback to set additional parameters (The XMLHTTPRequest object is passed to it as its only parameter).

Just so you know, this type of cross-domain request will not work in a normal site scenario and not with any other browser. I don't even know what security limitations FF 3.5 imposes as well, just so you don't beat your head against the wall for nothing:

$.ajax({
    url: 'http://bar.other',
    data: { whatever:'cool' },
    type: 'GET',
    beforeSend: function(xhr){
       xhr.withCredentials = true;
    }
});

One more thing to beware of, is that jQuery is setup to normalize browser differences. You may find that further limitations are imposed by the jQuery library that prohibit this type of functionality.

I have had LOTS of issues with the spinner firing of when I didn't want to, and all the answers here are unreliable. They work - but only sometimes. You will eventually run into scenarios where they will fail and introduce bugs into your code.

What worked for me was to store the last selected index in a variable and evaluate it in the listener. If it is the same as the new selected index do nothing and return, else continue with the listener. Do this:

//Declare a int member variable and initialize to 0 (at the top of your class)
private int mLastSpinnerPosition = 0;

//then evaluate it in your listener
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {

  if(mLastSpinnerPosition == i){
        return; //do nothing
  }

  mLastSpinnerPosition = i;
  //do the rest of your code now

}

Trust me when I say this, this is by far the most reliable solution. A hack, but it works!

Below worked for me, hope it helps someone!

const express = require('express');
const cors = require('cors');
let app = express();

app.use(cors({ origin: true }));

Got reference from https://expressjs.com/en/resources/middleware/cors.html#configuring-cors

There are multiple ways to achieve this one:-

1. Add $rootScope in .run method

.run(function ($rootScope) {
    $rootScope.name = "Peter";
});

// Controller
.controller('myController', function ($scope,$rootScope) {
    console.log("Name in rootscope ",$rootScope.name);
    OR
    console.log("Name in scope ",$scope.name);
});

2. Create one service and access it in both the controllers.

.factory('myFactory', function () {
     var object = {};

     object.users = ['John', 'James', 'Jake']; 

     return object;
})
// Controller A

.controller('ControllerA', function (myFactory) {
    console.log("In controller A ", myFactory);
})

// Controller B

.controller('ControllerB', function (myFactory) {
    console.log("In controller B ", myFactory);
})

Removing the href attribute definitely seems to the way to go. If for some reason you need it later, I would just store it in another attribute, e.g.

$(".my-link").each(function() {
    $(this).attr("data-oldhref", $(this).attr("href"));
    $(this).removeAttr("href");
});

This is the only way to do it that will make the link appear disabled as well without writing custom CSS. Just binding a click handler to false will make the link appear like a normal link, but nothing will happen when clicking on it, which may be confusing to users. If you are going to go the click handler route, I would at least also .addClass("link-disabled") and write some CSS that makes links with that class appear like normal text.

just CLEAN your project (CMD+SHIFT+K)

Although this post is very old. In case if somebody is looking for this..

Guava facilitates partitioning the List into sublists of a specified size

List<Integer> intList = Lists.newArrayList(1, 2, 3, 4, 5, 6, 7, 8);
    List<List<Integer>> subSets = Lists.partition(intList, 3);

If you want a variable to be accessible across the entire page, it works well to define it at the top of the file. (You can use either an implicit or explicit type.)

@{
    // implicit type
    var something1 = "something";

    // explicit type
    string something2 = "something";
}

<div>@something1</div> @*display first variable*@
<div>@something2</div> @*display second variable*@

Best solution which works like a charm

$fileContents= file_get_contents($url);

$fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);

$fileContents = trim(str_replace('"', "'", $fileContents));

$simpleXml = simplexml_load_string($fileContents);

//$json = json_encode($simpleXml); // Remove // if you want to store the result in $json variable

echo '<pre>'.json_encode($simpleXml,JSON_PRETTY_PRINT).'</pre>';

If the same error occurs in ADT/Eclipse

Add Action Bar Sherlock library in your project.

Now, to remove the "import The import android.support.v7 cannot be resolved" error download a jar file named as android-support-v7-appcompat.jar and add it in your project lib folder.

This will surely removes your both errors.

The reason for using dictionaries in the first place is performance. Although it is correct that you can use named vectors and lists for the task the issue is that they are becoming quite slow and memory hungry with more data.

Yet what many people don't know is that R has indeed an inbuilt dictionary data structure: environments with the option hash = TRUE

See the following example for how to make it work:

# vectorize assign, get and exists for convenience
assign_hash <- Vectorize(assign, vectorize.args = c("x", "value"))
get_hash <- Vectorize(get, vectorize.args = "x")
exists_hash <- Vectorize(exists, vectorize.args = "x")

# keys and values
key<- c("tic", "tac", "toe")
value <- c(1, 22, 333)

# initialize hash
hash = new.env(hash = TRUE, parent = emptyenv(), size = 100L)
# assign values to keys
assign_hash(key, value, hash)
## tic tac toe 
##   1  22 333
# get values for keys
get_hash(c("toe", "tic"), hash)
## toe tic 
## 333   1
# alternatively:
mget(c("toe", "tic"), hash)
## $toe
## [1] 333
## 
## $tic
## [1] 1
# show all keys
ls(hash)
## [1] "tac" "tic" "toe"
# show all keys with values
get_hash(ls(hash), hash)
## tac tic toe 
##  22   1 333
# remove key-value pairs
rm(list = c("toe", "tic"), envir = hash)
get_hash(ls(hash), hash)
## tac 
##  22
# check if keys are in hash
exists_hash(c("tac", "nothere"), hash)
##     tac nothere 
##    TRUE   FALSE
# for single keys this is also possible:
# show value for single key
hash[["tac"]]
## [1] 22
# create new key-value pair
hash[["test"]] <- 1234
get_hash(ls(hash), hash)
##  tac test 
##   22 1234
# update single value
hash[["test"]] <- 54321
get_hash(ls(hash), hash)
##   tac  test 
##    22 54321

Edit: On the basis of this answer I wrote a blog post with some more context: http://blog.ephorie.de/hash-me-if-you-can

I used

elm.children('.class-name-or-whatever') 

to get children of the current element

When you install third-party extensions you need to make sure that all the compilation parameters match:

• PHP version
• Architecture (32/64 bits)
• Compiler (VC9, VC10, VC11...)
• Thread safety

Common glitches includes:

• Editing the wrong php.ini file (that's typical with bundles); the right path is shown in phpinfo().
• Forgetting to restart Apache.

• Not being able to see the startup errors; those should show up in Apache logs, but you can also use the command line to diagnose it, e.g.:

  php -d display_startup_errors=1 -d error_reporting=-1 -d display_errors -c "C:\Path\To\php.ini" -m
  

If everything's right you should see sqlsrv in the command output and/or phpinfo() (depending on what SAPI you're configuring):

[PHP Modules]
bcmath
calendar
Core
[...]
SPL
sqlsrv
standard
[...]

Your technique will depend on what XAML object your SVG to XAML converter produces. Does it produce a Drawing? An Image? A Grid? A Canvas? A Path? A Geometry? In each case your technique will be different.

In the examples below I will assume you are using your icon on a button, which is the most common scenario, but note that the same techniques will work for any ContentControl.

Using a Drawing as an icon

To use a Drawing, paint an approriately-sized rectangle with a DrawingBrush:

<Button>
  <Rectangle Width="100" Height="100">
    <Rectangle.Fill>
      <DrawingBrush>
        <DrawingBrush.Drawing>

          <Drawing ... /> <!-- Converted from SVG -->

        </DrawingBrush.Drawing>
      </DrawingBrush>
    </Rectangle.Fill>
  </Rectangle>
</Button>

Using an Image as an icon

An image can be used directly:

<Button>
  <Image ... />  <!-- Converted from SVG -->
</Button>

Using a Grid as an icon

A grid can be used directly:

<Button>
  <Grid ... />  <!-- Converted from SVG -->
</Button>

Or you can include it in a Viewbox if you need to control the size:

<Button>
  <Viewbox ...>
    <Grid ... />  <!-- Converted from SVG -->
  </Viewbox>
</Button>

Using a Canvas as an icon

This is like using an image or grid, but since a canvas has no fixed size you need to specify the height and width (unless these are already set by the SVG converter):

<Button>
  <Canvas Height="100" Width="100">  <!-- Converted from SVG, with additions -->
  </Canvas>
</Button>

Using a Path as an icon

You can use a Path, but you must set the stroke or fill explicitly:

<Button>
  <Path Stroke="Red" Data="..." /> <!-- Converted from SVG, with additions -->
</Button>

or

<Button>
  <Path Fill="Blue" Data="..." /> <!-- Converted from SVG, with additions -->
</Button>

Using a Geometry as an icon

You can use a Path to draw your geometry. If it should be stroked, set the Stroke:

<Button>
  <Path Stroke="Red" Width="100" Height="100">
    <Path.Data>
      <Geometry ... /> <!-- Converted from SVG -->
    </Path.Data>
  </Path>
</Button>

or if it should be filled, set the Fill:

<Button>
  <Path Fill="Blue" Width="100" Height="100">
    <Path.Data>
      <Geometry ... /> <!-- Converted from SVG -->
    </Path.Data>
  </Path>
</Button>

How to data bind

If you're doing the SVG -> XAML conversion in code and want the resulting XAML to appear using data binding, use one of the following:

Binding a Drawing:

<Button>
  <Rectangle Width="100" Height="100">
    <Rectangle.Fill>
      <DrawingBrush Drawing="{Binding Drawing, Source={StaticResource ...}}" />
    </Rectangle.Fill>
  </Rectangle>
</Button>

Binding an Image:

<Button Content="{Binding Image}" />

Binding a Grid:

<Button Content="{Binding Grid}" />

Binding a Grid in a Viewbox:

<Button>
  <Viewbox ...>
    <ContentPresenter Content="{Binding Grid}" />
  </Viewbox>
</Button>

Binding a Canvas:

<Button>
  <ContentPresenter Height="100" Width="100" Content="{Binding Canvas}" />
</Button>

Binding a Path:

<Button Content="{Binding Path}" />  <!-- Fill or stroke must be set in code unless set by the SVG converter -->

Binding a Geometry:

<Button>
  <Path Width="100" Height="100" Data="{Binding Geometry}" />
</Button>

Convert a string to a DateTime, you could try

    DateTime timeValue = Convert.ToDateTime("01:00 PM");
    Console.WriteLine(timeValue.ToString("HH:mm"));

Here is my implementation of a Java enumeration in JavaScript.

I also included unit tests.

  mocha.setup('bdd')

  describe('Test Color [From Array]', function() {
    let Color = new Enum('RED', 'BLUE', 'GREEN')

    })

      chai.assert.isNotNull(Color.BLUE)
    })

    it('Test: Color.GREEN', () => {

    })
  })

Update

Here is a more up-to-date version that satisfies MDN.

The Object.prototype.__defineGetter__ has been replaced by Object.defineProperty per MDN's recomendation:

This feature is deprecated in favor of defining getters using the object initializer syntax or the Object.defineProperty() API. While this feature is widely implemented, it is only described in the ECMAScript specification because of legacy usage. This method should not be used since better alternatives exist.

If you want to avoid drawing it yourself, you could use the undocumented class: UINavigationButton with style 1. This could, of course, stop your application from being approved... /John

Please create a custom TextView and use it :

public class CustomTextView extends TextView {

    public CapitalizedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        if (text.length() > 0) {
            text = String.valueOf(text.charAt(0)).toUpperCase() + text.subSequence(1, text.length());
        }
        super.setText(text, type);
    }
}

I faced the same problem and the reason was that I was using ngModel in my MenuComponent. I imported my MenuComponent in app.module.ts, but I forgot to declare it.

Declaring the MenuComponent solved my issue. I.e., as shown in the below image:

I think np.isnan(np.min(X)) should do what you want.

SO @NotNull just is a tag...If you want to validate it, then you must use something like hibernate validator jsr 303

ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
Validator validator = validatorFactory.getValidator();
 Set<ConstraintViolation<List<Searching>> violations = validator.validate(searchingList);

In Swift 4.2 and Xcode 10.1

//Email validation
func isValidEmail(email: String) -> Bool {
    let emailRegex = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}"
    var valid = NSPredicate(format: "SELF MATCHES %@", emailRegex).evaluate(with: email)
    if valid {
        valid = !email.contains("Invalid email id")
    }
    return valid
}

//Use like this....
let emailTrimmedString = emailTF.text?.trimmingCharacters(in: .whitespaces)
if isValidEmail(email: emailTrimmedString!) == false {
   SharedClass.sharedInstance.alert(view: self, title: "", message: "Please enter valid email")
}

If you want to use SharedClass.

//This is SharedClass
import UIKit
class SharedClass: NSObject {

static let sharedInstance = SharedClass()

//Email validation
func isValidEmail(email: String) -> Bool {
    let emailRegex = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}"
    var valid = NSPredicate(format: "SELF MATCHES %@", emailRegex).evaluate(with: email)
    if valid {
        valid = !email.contains("Invalid email id")
    }
    return valid
}

private override init() {

}
}

And call function like this....

if SharedClass.sharedInstance. isValidEmail(email: emailTrimmedString!) == false {
   SharedClass.sharedInstance.alert(view: self, title: "", message: "Please enter correct email")
   //Your code here
} else {
   //Code here
}

I have not seen many solutions to this problem. Some solutions make use of directory traversal using CD and others make use of batch functions. My personal preference has been for batch functions and in particular, the MakeAbsolute function as provided by DosTips.

The function has some real benefits, primarily that it does not change your current working directory and secondly that the paths being evaluated don't even have to exist. You can find some helpful tips on how to use the function here too.

Here is an example script and its outputs:

@echo off

set scriptpath=%~dp0
set siblingfile=sibling.bat
set siblingfolder=sibling\
set fnwsfolder=folder name with spaces\
set descendantfolder=sibling\descendant\
set ancestorfolder=..\..\
set cousinfolder=..\uncle\cousin

call:MakeAbsolute siblingfile      "%scriptpath%"
call:MakeAbsolute siblingfolder    "%scriptpath%"
call:MakeAbsolute fnwsfolder       "%scriptpath%"
call:MakeAbsolute descendantfolder "%scriptpath%"
call:MakeAbsolute ancestorfolder   "%scriptpath%"
call:MakeAbsolute cousinfolder     "%scriptpath%"

echo scriptpath:       %scriptpath%
echo siblingfile:      %siblingfile%
echo siblingfolder:    %siblingfolder%
echo fnwsfolder:       %fnwsfolder%
echo descendantfolder: %descendantfolder%
echo ancestorfolder:   %ancestorfolder%
echo cousinfolder:     %cousinfolder%

I hope this helps... It sure helped me :) P.S. Thanks again to DosTips! You rock!

Additionally if someone have a use case where he needs group names before executing search on Regex object he can use:

var regex = new Regex(pattern); // initialized somewhere
// ...
var groupNames = regex.GetGroupNames();

When you specify the last Directory on the path remove the last .

for example "\server\directory with space\directory with space".

that should do it.

If the previous answers do not solve your problem, check the source of the data that won't print/convert properly.

In my case, I was using json.load on data incorrectly read from file by not using the encoding="utf-8". Trying to de-/encode the resulting string to latin-1 just does not help...

If you don't want to use libraries or other things, you can use this native javascript approach:

var MD5 = function(d){var r = M(V(Y(X(d),8*d.length)));return r.toLowerCase()};function M(d){for(var _,m="0123456789ABCDEF",f="",r=0;r<d.length;r++)_=d.charCodeAt(r),f+=m.charAt(_>>>4&15)+m.charAt(15&_);return f}function X(d){for(var _=Array(d.length>>2),m=0;m<_.length;m++)_[m]=0;for(m=0;m<8*d.length;m+=8)_[m>>5]|=(255&d.charCodeAt(m/8))<<m%32;return _}function V(d){for(var _="",m=0;m<32*d.length;m+=8)_+=String.fromCharCode(d[m>>5]>>>m%32&255);return _}function Y(d,_){d[_>>5]|=128<<_%32,d[14+(_+64>>>9<<4)]=_;for(var m=1732584193,f=-271733879,r=-1732584194,i=271733878,n=0;n<d.length;n+=16){var h=m,t=f,g=r,e=i;f=md5_ii(f=md5_ii(f=md5_ii(f=md5_ii(f=md5_hh(f=md5_hh(f=md5_hh(f=md5_hh(f=md5_gg(f=md5_gg(f=md5_gg(f=md5_gg(f=md5_ff(f=md5_ff(f=md5_ff(f=md5_ff(f,r=md5_ff(r,i=md5_ff(i,m=md5_ff(m,f,r,i,d[n+0],7,-680876936),f,r,d[n+1],12,-389564586),m,f,d[n+2],17,606105819),i,m,d[n+3],22,-1044525330),r=md5_ff(r,i=md5_ff(i,m=md5_ff(m,f,r,i,d[n+4],7,-176418897),f,r,d[n+5],12,1200080426),m,f,d[n+6],17,-1473231341),i,m,d[n+7],22,-45705983),r=md5_ff(r,i=md5_ff(i,m=md5_ff(m,f,r,i,d[n+8],7,1770035416),f,r,d[n+9],12,-1958414417),m,f,d[n+10],17,-42063),i,m,d[n+11],22,-1990404162),r=md5_ff(r,i=md5_ff(i,m=md5_ff(m,f,r,i,d[n+12],7,1804603682),f,r,d[n+13],12,-40341101),m,f,d[n+14],17,-1502002290),i,m,d[n+15],22,1236535329),r=md5_gg(r,i=md5_gg(i,m=md5_gg(m,f,r,i,d[n+1],5,-165796510),f,r,d[n+6],9,-1069501632),m,f,d[n+11],14,643717713),i,m,d[n+0],20,-373897302),r=md5_gg(r,i=md5_gg(i,m=md5_gg(m,f,r,i,d[n+5],5,-701558691),f,r,d[n+10],9,38016083),m,f,d[n+15],14,-660478335),i,m,d[n+4],20,-405537848),r=md5_gg(r,i=md5_gg(i,m=md5_gg(m,f,r,i,d[n+9],5,568446438),f,r,d[n+14],9,-1019803690),m,f,d[n+3],14,-187363961),i,m,d[n+8],20,1163531501),r=md5_gg(r,i=md5_gg(i,m=md5_gg(m,f,r,i,d[n+13],5,-1444681467),f,r,d[n+2],9,-51403784),m,f,d[n+7],14,1735328473),i,m,d[n+12],20,-1926607734),r=md5_hh(r,i=md5_hh(i,m=md5_hh(m,f,r,i,d[n+5],4,-378558),f,r,d[n+8],11,-2022574463),m,f,d[n+11],16,1839030562),i,m,d[n+14],23,-35309556),r=md5_hh(r,i=md5_hh(i,m=md5_hh(m,f,r,i,d[n+1],4,-1530992060),f,r,d[n+4],11,1272893353),m,f,d[n+7],16,-155497632),i,m,d[n+10],23,-1094730640),r=md5_hh(r,i=md5_hh(i,m=md5_hh(m,f,r,i,d[n+13],4,681279174),f,r,d[n+0],11,-358537222),m,f,d[n+3],16,-722521979),i,m,d[n+6],23,76029189),r=md5_hh(r,i=md5_hh(i,m=md5_hh(m,f,r,i,d[n+9],4,-640364487),f,r,d[n+12],11,-421815835),m,f,d[n+15],16,530742520),i,m,d[n+2],23,-995338651),r=md5_ii(r,i=md5_ii(i,m=md5_ii(m,f,r,i,d[n+0],6,-198630844),f,r,d[n+7],10,1126891415),m,f,d[n+14],15,-1416354905),i,m,d[n+5],21,-57434055),r=md5_ii(r,i=md5_ii(i,m=md5_ii(m,f,r,i,d[n+12],6,1700485571),f,r,d[n+3],10,-1894986606),m,f,d[n+10],15,-1051523),i,m,d[n+1],21,-2054922799),r=md5_ii(r,i=md5_ii(i,m=md5_ii(m,f,r,i,d[n+8],6,1873313359),f,r,d[n+15],10,-30611744),m,f,d[n+6],15,-1560198380),i,m,d[n+13],21,1309151649),r=md5_ii(r,i=md5_ii(i,m=md5_ii(m,f,r,i,d[n+4],6,-145523070),f,r,d[n+11],10,-1120210379),m,f,d[n+2],15,718787259),i,m,d[n+9],21,-343485551),m=safe_add(m,h),f=safe_add(f,t),r=safe_add(r,g),i=safe_add(i,e)}return Array(m,f,r,i)}function md5_cmn(d,_,m,f,r,i){return safe_add(bit_rol(safe_add(safe_add(_,d),safe_add(f,i)),r),m)}function md5_ff(d,_,m,f,r,i,n){return md5_cmn(_&m|~_&f,d,_,r,i,n)}function md5_gg(d,_,m,f,r,i,n){return md5_cmn(_&f|m&~f,d,_,r,i,n)}function md5_hh(d,_,m,f,r,i,n){return md5_cmn(_^m^f,d,_,r,i,n)}function md5_ii(d,_,m,f,r,i,n){return md5_cmn(m^(_|~f),d,_,r,i,n)}function safe_add(d,_){var m=(65535&d)+(65535&_);return(d>>16)+(_>>16)+(m>>16)<<16|65535&m}function bit_rol(d,_){return d<<_|d>>>32-_}_x000D_

For non english words you may need to use unescape() and the encodeURIComponent() methods.

Only thing that comes even close is the :contains pseudo class in CSS3, but that only selects textual content, not tags or elements, so you're out of luck.

A simpler way to select a parent with specific children in jQuery can be written as (with :has()):

$('#parent:has(#child)');

regexp:

"014".replace(/^0+/, '')

Try something like this:

public boolean checkNull() throws IllegalAccessException {
    for (Field f : getClass().getDeclaredFields())
        if (f.get(this) != null)
            return false;
    return true;            
}

Although it would probably be better to check each variable if at all feasible.

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

tar -zxf tmp.tar.gz -C ~/tmp1

Here's how you do this with react-router v2.0.0 with ES6. react-router has moved away from mixins.

import React from 'react';

export default class MyComponent extends React.Component {
  navigateToPage = () => {
    this.context.router.push('/my-route')
  };

  render() {
    return (
      <button onClick={this.navigateToPage}>Go!</button>
    );
  }
}

MyComponent.contextTypes = {
  router: React.PropTypes.object.isRequired
}

s.index(x[, i[, j]])

index of the first occurrence of x in s (at or after index i and before index j)

You cannot change the manifest or the resource in the signed-and-sealed APK, except through a software upgrade.

& is used for bit-wise comparison. use and instead. and btw, you don't need semicolon at the end of print statement.

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

https://www.w3schools.com/sql/func_mysql_strcmp.asp

var app=angular.module('myApp',[]);
        app.controller('myController',function($scope){         
              $scope.names = ['1288323623006','1388323623006'];

        });

Here Controller name is "myController" and app name is "myApp".

<div ng-app="myApp" ng-controller="myController">
        <ul>
            <li ng-repeat="x in names">
                {{x | date:'mm-dd-yyyy'}}

            </li>

        </ul>
    </div>

Result will look like this :- * 10-29-2010 * 01-03-2013

Quoting the Forms Page in the HTML manual:

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.

With the latest SDK-Tools, you can now use a tool called the apkanalyzer to print out the AndroidManifest.xml of an APK (as well as other parts, such as resources).

[android sdk]/tools/bin/apkanalyzer manifest print [app.apk]

apkanalyzer

Here is a more general way that is a bit cleaner:

Create your form like this (can be a dummy form that does nothing):

<form class="validateDontSubmit">
...

Bind all forms that you dont really want to submit:

$(document).on('submit','.validateDontSubmit',function (e) {
    //prevent the form from doing a submit
    e.preventDefault();
    return false;
})

Now lets say you have an <a> (within the <form>) that on click you want to validate the form:

$('#myLink').click(function(e){
  //Leverage the HTML5 validation w/ ajax. Have to submit to get em. Wont actually submit cuz form
  //has .validateDontSubmit class
  var $theForm = $(this).closest('form');
  //Some browsers don't implement checkValidity
  if (( typeof($theForm[0].checkValidity) == "function" ) && !$theForm[0].checkValidity()) {
     return;
  }

  //if you've gotten here - play on playa'
});

Few notes here:

• I have noticed that you don't have to actually submit the form for validation to occur - the call to checkValidity() is enough (at least in chrome). If others could add comments with testing this theory on other browsers I'll update this answer.
• The thing that triggers the validation does not have to be within the <form>. This was just a clean and flexible way to have a general purpose solution..

There is the semicolon missing (;) after the "50%"

but you should also notice that the percentage of your div is connected to the div that contains it.

for instance:

<div id="wrapper">
  <div class="container">
   adsf
  </div>
</div>

#wrapper {
  height:100px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

here the height of your .container will be 50px. it will be 50% of the 100px from the wrapper div.

if you have:

adsf

#wrapper {
  height:400px;
}
.container
{
  width:80%;
  height:50%;
  background-color:#eee;
}

then you .container will be 200px. 50% of the wrapper.

So you may want to look at the divs "wrapping" your ".container"...
