Put novalidate="novalidate" on <form> tag.

<form novalidate="novalidate">
...
</form>

In XHTML, attribute minimization is forbidden, and the novalidate attribute must be defined as <form novalidate="novalidate">.

Use the json module to produce JSON output:

import json

with open(outputfilename, 'wb') as outfile:
    json.dump(row, outfile)

This writes the JSON result directly to the file (replacing any previous content if the file already existed).

If you need the JSON result string in Python itself, use json.dumps() (added s, for 'string'):

json_string = json.dumps(row)

The L is just Python syntax for a long integer value; the json library knows how to handle those values, no L will be written.

Demo string output:

>>> import json
>>> row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]
>>> json.dumps(row)
'[1, [0.1, 0.2], [[1234, 1], [134, 2]]]'

select 'DROP TABLE ' + name from sysobjects
where type = 'U' and sysobjects.name like '%test%'

-- Test is the table name

table tr td:nth-child(2) {
    background: #ccc;
}

Working example: http://jsfiddle.net/gqr3J/

This syntax is from the Visual Basic Select...Case Statement:

Dim number As Integer = 8
Select Case number
    Case 1 To 5
        Debug.WriteLine("Between 1 and 5, inclusive")
        ' The following is the only Case clause that evaluates to True.
    Case 6, 7, 8
        Debug.WriteLine("Between 6 and 8, inclusive")
    Case Is < 1
        Debug.WriteLine("Equal to 9 or 10")
    Case Else
        Debug.WriteLine("Not between 1 and 10, inclusive")
End Select

You cannot use this syntax in C#. Instead, you must use the syntax from your first example.

If you have one large dataframe and only a few update values I would use apply like this:

import pandas as pd

df = pd.DataFrame({'filename' :  ['test0.dat', 'test2.dat'], 
                                  'm': [12, 13], 'n' : [None, None]})

data = {'filename' :  'test2.dat', 'n':16}

def update_vals(row, data=data):
    if row.filename == data['filename']:
        row.n = data['n']
    return row

df.apply(update_vals, axis=1)

If you are using the [WebInvoke(Method="GET")] attribute on the service method, make sure that you spell the method name as "GET" and not "Get" or "get" since it is case sensitive! I had the same error and it took me an hour to figure that one out.

Up until the C99 standard, all declarations had to come before any statements in a block:

void foo()
{
  int i, j;
  double k;
  char *c;

  // code

  if (c)
  {
    int m, n;

    // more code
  }
  // etc.
}

C99 allowed for mixing declarations and statements (like C++). Many compilers still default to C89, and some compilers (such as Microsoft's) don't support C99 at all.

So, you will need to do the following:

1. Determine if your compiler supports C99 or later; if it does, configure it so that it's compiling C99 instead of C89;

2. If your compiler doesn't support C99 or later, you will either need to find a different compiler that does support it, or rewrite your code so that all declarations come before any statements within the block.

As alternate solution, based on javascript logic operator '&&' which returns the last evaluation, you can also do this like so:

<i ng-class="autoScroll && 'icon-autoscroll' || !autoScroll && 'icon-autoscroll-disabled'"></i>

It's only slightly shorter syntax, but for me easier to read.

If the report designer is opened, Report Data Pane can be enabled using view menu.

 View -> Report Data

to get the object you do not need to use cURL (you are loading another dll into memory and have another dependency, unless you really need curl I'd stick with built in php functions), you can use one simple php file_get_contents(url) function: http://il1.php.net/manual/en/function.file-get-contents.php

$unparsed_json = file_get_contents("api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1");

$json_object = json_decode($unparsed_json);

then json_decode() parses JSON into a PHP object, or an array if you pass true to the second parameter. http://php.net/manual/en/function.json-decode.php

For example:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));           // Object
var_dump(json_decode($json, true));     // Associative array

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

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

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

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

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

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

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

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

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

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

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

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

after that make changes like this:

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

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

<?

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

?>

cheers :-)

In my case i had set:

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

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

<script>
function deleteItem()
{
   var resp = confirm("Do you want to delete this item???");
   if (resp == true) {
      //do something
   } 
   else {
      //do something
   }
}
</script>

call this function using onClick

You can try this click event

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex >= 0)
    {
        DataGridViewRow row = this.dataGridView1.Rows[e.RowIndex];
        Eid_txt.Text = row.Cells["Employee ID"].Value.ToString();
        Name_txt.Text = row.Cells["First Name"].Value.ToString();
        Surname_txt.Text = row.Cells["Last Name"].Value.ToString();

The general rule seems to be that browsers encode form responses according to the content-type of the page the form was served from. This is a guess that if the server sends us "text/xml; charset=iso-8859-1", then they expect responses back in the same format.

If you're just entering a URL in the URL bar, then the browser doesn't have a base page to work on and therefore just has to guess. So in this case it seems to be doing utf-8 all the time (since both your inputs produced three-octet form values).

The sad truth is that AFAIK there's no standard for what character set the values in a query string, or indeed any characters in the URL, should be interpreted as. At least in the case of values in the query string, there's no reason to suppose that they necessarily do correspond to characters.

It's a known problem that you have to tell your server framework which character set you expect the query string to be encoded as--- for instance, in Tomcat, you have to call request.setEncoding() (or some similar method) before you call any of the request.getParameter() methods. The dearth of documentation on this subject probably reflects the lack of awareness of the problem amongst many developers. (I regularly ask Java interviewees what the difference between a Reader and an InputStream is, and regularly get blank looks)

I had the same error in Chrome. The Chrome console told me that the error was in the 1st line of the HTML file.

It was actually in the .js file. So watch out for setValidNou(1060, $(this).val(), 0') error types.

It is worth noting that if you are returning server side data - you must supply the Data attribute even if there isn't any. It doesn't read the recordsTotal or recordsFiltered but relies on the count of the data object

Import namespace :

using System.Configuration;

Create ConfigurationElement Company :

public class Company : ConfigurationElement
{

        [ConfigurationProperty("name", IsRequired = true)]
        public string Name
        {
            get
            {
                return this["name"] as string;
            }
        }
            [ConfigurationProperty("code", IsRequired = true)]
        public string Code
        {
            get
            {
                return this["code"] as string;
            }
        }
}

ConfigurationElementCollection:

public class Companies
        : ConfigurationElementCollection
    {
        public Company this[int index]
        {
            get
            {
                return base.BaseGet(index) as Company ;
            }
            set
            {
                if (base.BaseGet(index) != null)
                {
                    base.BaseRemoveAt(index);
                }
                this.BaseAdd(index, value);
            }
        }

       public new Company this[string responseString]
       {
            get { return (Company) BaseGet(responseString); }
            set
            {
                if(BaseGet(responseString) != null)
                {
                    BaseRemoveAt(BaseIndexOf(BaseGet(responseString)));
                }
                BaseAdd(value);
            }
        }

        protected override System.Configuration.ConfigurationElement CreateNewElement()
        {
            return new Company();
        }

        protected override object GetElementKey(System.Configuration.ConfigurationElement element)
        {
            return ((Company)element).Name;
        }
    }

and ConfigurationSection:

public class RegisterCompaniesConfig
        : ConfigurationSection
    {

        public static RegisterCompaniesConfig GetConfig()
        {
            return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig();
        }

        [System.Configuration.ConfigurationProperty("Companies")]
            [ConfigurationCollection(typeof(Companies), AddItemName = "Company")]
        public Companies Companies
        {
            get
            {
                object o = this["Companies"];
                return o as Companies ;
            }
        }

    }

and you must also register your new configuration section in web.config (app.config):

<configuration>       
    <configSections>
          <section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>

then you load your config with

var config = RegisterCompaniesConfig.GetConfig();
foreach(var item in config.Companies)
{
   do something ..
}

It's a designated initializer, introduced with the C99 standard; it allows you to initialize specific members of a struct or union object by name. my_data is obviously a typedef for a struct type that has a member name of type char * or char [N].

This works from command line :

$ export LANG=en_US.UTF-8

None of the other answers above worked for me

I found this post because I was having the same error in Microsoft Visual C++. (Though it seems it's cause was a little different, than the above posted question.)

I had placed the file, I was trying to include, in the same directory, but it still could not be found.

My include looked like this: #include <ftdi.h>

But When I changed it to this: #include "ftdi.h" then it found it.

Generic solution extracting the first "n" words of refcell string into a new string of "x" number of characters

=LEFT(SUBSTITUTE(***refcell***&" "," ",REPT(" ",***x***),***n***),***x***)

Assuming A1 has text string to extract, the 1st word extracted to a 15 character result

=LEFT(SUBSTITUTE(A1&" "," ",REPT(" ",15),1),15)

This would result in "Toronto" being returned to a 15 character string. 1st 2 words extracted to a 30 character result

=LEFT(SUBSTITUTE(A1&" "," ",REPT(" ",30),2),30)

would result in "Toronto is" being returned to a 30 character string

If you are using reactiveFormModule and have formGroup defined like this:

public exampleForm = new FormGroup({
        name: new FormControl('Test name', [Validators.required, Validators.minLength(3)]),
        email: new FormControl('[email protected]', [Validators.required, Validators.maxLength(50)]),
        age: new FormControl(45, [Validators.min(18), Validators.max(65)])
});

than you are able to add a new validator (and keep old ones) to FormControl with this approach:

this.exampleForm.get('age').setValidators([
        Validators.pattern('^[0-9]*$'),
        this.exampleForm.get('age').validator
]);
this.exampleForm.get('email').setValidators([
        Validators.email,
        this.exampleForm.get('email').validator
]);

FormControl.validator returns a compose validator containing all previously defined validators.

UPDATE: Here is something I put together that will style the table:

<script type="text/javascript">

    (function ($) {
        $.fn.styleTable = function (options) {
            var defaults = {
                css: 'styleTable'
            };
            options = $.extend(defaults, options);

            return this.each(function () {

                input = $(this);
                input.addClass(options.css);

                input.find("tr").live('mouseover mouseout', function (event) {
                    if (event.type == 'mouseover') {
                        $(this).children("td").addClass("ui-state-hover");
                    } else {
                        $(this).children("td").removeClass("ui-state-hover");
                    }
                });

                input.find("th").addClass("ui-state-default");
                input.find("td").addClass("ui-widget-content");

                input.find("tr").each(function () {
                    $(this).children("td:not(:first)").addClass("first");
                    $(this).children("th:not(:first)").addClass("first");
                });
            });
        };
    })(jQuery);

    $(document).ready(function () {
        $("#Table1").styleTable();
    });

</script>

<table id="Table1" class="full">
    <tr>
        <th>one</th>
        <th>two</th>
    </tr>
    <tr>
        <td>1</td>
        <td>2</td>
    </tr>
    <tr>
        <td>1</td>
        <td>2</td>
    </tr>
</table>

The CSS:

.styleTable { border-collapse: separate; }
.styleTable TD { font-weight: normal !important; padding: .4em; border-top-width: 0px !important; }
.styleTable TH { text-align: center; padding: .8em .4em; }
.styleTable TD.first, .styleTable TH.first { border-left-width: 0px !important; }

something like:

$("ul#wizard li").click(function () {
  var index = $("ul#wizard li").index(this);
  alert("index is: " + index)
});

This is same as the previous solution but I have defined the function in df.apply itself:

df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)

If you know to get the root directory:

string rootPath = Path.GetPathRoot(Application.StartupPath)

git reset does know five "modes": soft, mixed, hard, merge and keep. I will start with the first three, since these are the modes you'll usually encounter. After that you'll find a nice little a bonus, so stay tuned.

soft

When using git reset --soft HEAD~1 you will remove the last commit from the current branch, but the file changes will stay in your working tree. Also the changes will stay on your index, so following with a git commit will create a commit with the exact same changes as the commit you "removed" before.

mixed

This is the default mode and quite similar to soft. When "removing" a commit with git reset HEAD~1 you will still keep the changes in your working tree but not on the index; so if you want to "redo" the commit, you will have to add the changes (git add) before commiting.

hard

When using git reset --hard HEAD~1 you will lose all uncommited changes in addition to the changes introduced in the last commit. The changes won't stay in your working tree so doing a git status command will tell you that you don't have any changes in your repository.

Tread carefully with this one. If you accidentally remove uncommited changes which were never tracked by git (speak: committed or at least added to the index), you have no way of getting them back using git.

Bonus

keep

git reset --keep HEAD~1 is an interesting and useful one. It only resets the files which are different between the current HEAD and the given commit. It aborts the reset if one or more of these files has uncommited changes. It basically acts as a safer version of hard.

You can read more about that in the git reset documentation.

Note
When doing git reset to remove a commit the commit isn't really lost, there just is no reference pointing to it or any of it's children. You can still recover a commit which was "deleted" with git reset by finding it's SHA-1 key, for example with a command such as git reflog.

It is not necessary to have two routes.

Simply add (/*)? at the end of your path string.

For example, app.get('/hello/world(/*)?' /* ... */)

Here is a fully working example, feel free to copy and paste this into a .js file to run with node, and play with it in a browser (or curl):

const app = require('express')()

// will be able to match all of the following
const test1 = 'http://localhost:3000/hello/world'
const test2 = 'http://localhost:3000/hello/world/'
const test3 = 'http://localhost:3000/hello/world/with/more/stuff'

// but fail at this one
const failTest = 'http://localhost:3000/foo/world'

app.get('/hello/world(/*)?', (req, res) => res.send(`
    This will match at example endpoints: <br><br>
    <pre><a href="${test1}">${test1}</a></pre>
    <pre><a href="${test2}">${test2}</a></pre>
    <pre><a href="${test3}">${test3}</a></pre>

    <br><br> Will NOT match at: <pre><a href="${failTest}">${failTest}</a></pre>
`))

app.listen(3000, () => console.log('Check this out in a browser at http://localhost:3000/hello/world!'))

Your JavaScript would have to be defined within a PHP-parsed file.

For example, in index.php you could place

<?php
$time = time();
?>
<script>
    document.write(<?php echo $time; ?>);
</script>

You have to disable Globals

 /**
 * @backupGlobals disabled
 */

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

If the requirement is to reference the global object (JavaScript) in your HTML code, you can try this. [Don't use any quotes (' or ") around the variable]

Fiddle reference.

JavaScript:

var result = {name: 'hello'};
function gotoNode(name) {
    alert(name);
}

HTML:

<input value="Hello" type="button" onClick="gotoNode(result.name)" />?

In C, a string is actually stored as an array of characters, so the 'string pointer' is pointing to the first character. For instance,

char myString[] = "This is some text";

You can access any character as a simple char by using myString as an array, thus:

char myChar = myString[6];
printf("%c\n", myChar); // Prints s

Hope this helps! David

It is an old post, but I came across this recently

Selecting a specific interval

As @aleroot already mentioned, by using

table.setRowSelectionInterval(index0, index1);

You can specify an interval, which should be selected.

Adding an interval to the existing selection

You can also keep the current selection, and simply add additional rows by using this here

table.getSelectionModel().addSelectionInterval(index0, index1);

This line of code additionally selects the specified interval. It doesn't matter if that interval already is selected, of parts of it are selected.

Below mentioned link gives the clear explanation with example.

                UIAlertAction in
                NSLog("Cancel Pressed")
            }

            // Add the actions
            alertController.addAction(okAction)
            alertController.addAction(cancelAction)

            // Present the controller
            self.present(alertController, animated: true, completion: nil)

TL;DR:

No, don't subscribe manually to them, don't use them in services. Use them as is shown in the documentation only to emit events in components. Don't defeat angular's abstraction.

Answer:

No, you should not subscribe manually to it.

EventEmitter is an angular2 abstraction and its only purpose is to emit events in components. Quoting a comment from Rob Wormald

[...] EventEmitter is really an Angular abstraction, and should be used pretty much only for emitting custom Events in components. Otherwise, just use Rx as if it was any other library.

This is stated really clear in EventEmitter's documentation.

Use by directives and components to emit custom Events.

What's wrong about using it?

Angular2 will never guarantee us that EventEmitter will continue being an Observable. So that means refactoring our code if it changes. The only API we must access is its emit() method. We should never subscribe manually to an EventEmitter.

All the stated above is more clear in this Ward Bell's comment (recommended to read the article, and the answer to that comment). Quoting for reference

Do NOT count on EventEmitter continuing to be an Observable!

Do NOT count on those Observable operators being there in the future!

These will be deprecated soon and probably removed before release.

Use EventEmitter only for event binding between a child and parent component. Do not subscribe to it. Do not call any of those methods. Only call eve.emit()

His comment is in line with Rob's comment long time ago.

So, how to use it properly?

Simply use it to emit events from your component. Take a look a the following example.

@Component({
    selector : 'child',
    template : `
        <button (click)="sendNotification()">Notify my parent!</button>
    `
})
class Child {
    @Output() notifyParent: EventEmitter<any> = new EventEmitter();
    sendNotification() {
        this.notifyParent.emit('Some value to send to the parent');
    }
}

@Component({
    selector : 'parent',
    template : `
        <child (notifyParent)="getNotification($event)"></child>
    `
})
class Parent {
    getNotification(evt) {
        // Do something with the notification (evt) sent by the child!
    }
}

How not to use it?

class MyService {
    @Output() myServiceEvent : EventEmitter<any> = new EventEmitter();
}

Stop right there... you're already wrong...

Hopefully these two simple examples will clarify EventEmitter's proper usage.

Add type="text/babel" as an attribute of the script tag, like this:

<script type="text/babel" src="./lander.js"></script>

give a try to this class:

class PrimitiveWrapper<T> extends AbstractList<T> {

    private final T[] data;

    private PrimitiveWrapper(T[] data) {
        this.data = data; // you can clone this array for preventing aliasing
    }

    public static <T> List<T> ofIntegers(int... data) {
        return new PrimitiveWrapper(toBoxedArray(Integer.class, data));
    }

    public static <T> List<T> ofCharacters(char... data) {
        return new PrimitiveWrapper(toBoxedArray(Character.class, data));
    }

    public static <T> List<T> ofDoubles(double... data) {
        return new PrimitiveWrapper(toBoxedArray(Double.class, data));
    }  

    // ditto for byte, float, boolean, long

    private static <T> T[] toBoxedArray(Class<T> boxClass, Object components) {
        final int length = Array.getLength(components);
        Object res = Array.newInstance(boxClass, length);

        for (int i = 0; i < length; i++) {
            Array.set(res, i, Array.get(components, i));
        }

        return (T[]) res;
    }

    @Override
    public T get(int index) {
        return data[index];
    }

    @Override
    public int size() {
        return data.length;
    }
}

testcase:

List<Integer> ints = PrimitiveWrapper.ofIntegers(10, 20);
List<Double> doubles = PrimitiveWrapper.ofDoubles(10, 20);
// etc

Setting the android:scrollbarFadeDuration="0" will do the trick.

As of .NET Core 2.0, the constructor Dictionary<TKey,TValue>(IEnumerable<KeyValuePair<TKey,TValue>>) now exists.

You can use [ActionName("NewActionName")] to use the same method with a different name:

public class HomeController : Controller
{
    public ActionResult GetEmpName()
    {
        return Content("This is the test Message");
    }

    [ActionName("GetEmpWithCode")]
    public ActionResult GetEmpName(string EmpCode)
    {
        return Content("This is the test Messagewith Overloaded");
    }
}

Your negative lookahead solution would e.g. be this:

You want a proc object:

gaussian = Proc.new do |dist, *args|
  sigma = args.first || 10.0
  ...
end

def weightedknn(data, vec1, k = 5, weightf = gaussian)
  ...
  weight = weightf.call(dist)
  ...
end

Just note that you can't set a default argument in a block declaration like that. So you need to use a splat and setup the default in the proc code itself.

Or, depending on your scope of all this, it may be easier to pass in a method name instead.

def weightedknn(data, vec1, k = 5, weightf = :gaussian)
  ...
  weight = self.send(weightf)
  ...
end

In this case you are just calling a method that is defined on an object rather than passing in a complete chunk of code. Depending on how you structure this you may need replace self.send with object_that_has_the_these_math_methods.send

Last but not least, you can hang a block off the method.

def weightedknn(data, vec1, k = 5)
  ...
  weight = 
    if block_given?
      yield(dist)
    else
      gaussian.call(dist)
    end
  end
  ...
end

weightedknn(foo, bar) do |dist|
  # square the dist
  dist * dist
end

But it sounds like you would like more reusable chunks of code here.

TableA LEFT OUTER JOIN TableB is equivalent to TableB RIGHT OUTER JOIN Table A.

In Oracle, (+) denotes the "optional" table in the JOIN. So in your first query, it's a P LEFT OUTER JOIN S. In your second query, it's S RIGHT OUTER JOIN P. They're functionally equivalent.

In the terminology, RIGHT or LEFT specify which side of the join always has a record, and the other side might be null. So in a P LEFT OUTER JOIN S, P will always have a record because it's on the LEFT, but S could be null.

See this example from java2s.com for additional explanation.

To clarify, I guess I'm saying that terminology doesn't matter, as it's only there to help visualize. What matters is that you understand the concept of how it works.

RIGHT vs LEFT

I've seen some confusion about what matters in determining RIGHT vs LEFT in implicit join syntax.

LEFT OUTER JOIN

SELECT *
FROM A, B
WHERE A.column = B.column(+)

RIGHT OUTER JOIN

SELECT *
FROM A, B
WHERE B.column(+) = A.column

All I did is swap sides of the terms in the WHERE clause, but they're still functionally equivalent. (See higher up in my answer for more info about that.) The placement of the (+) determines RIGHT or LEFT. (Specifically, if the (+) is on the right, it's a LEFT JOIN. If (+) is on the left, it's a RIGHT JOIN.)

Types of JOIN

The two styles of JOIN are implicit JOINs and explicit JOINs. They are different styles of writing JOINs, but they are functionally equivalent.

See this SO question.

Implicit JOINs simply list all tables together. The join conditions are specified in a WHERE clause.

Implicit JOIN

SELECT *
FROM A, B
WHERE A.column = B.column(+)

Explicit JOINs associate join conditions with a specific table's inclusion instead of in a WHERE clause.

Explicit JOIN

SELECT *
FROM A
LEFT OUTER JOIN B ON A.column = B.column

These Implicit JOINs can be more difficult to read and comprehend, and they also have a few limitations since the join conditions are mixed in other WHERE conditions. As such, implicit JOINs are generally recommended against in favor of explicit syntax.

hope this would help:

Decoding base64 to UTF8 String

Below is current most voted answer by @brandonscript

function b64DecodeUnicode(str) {
    // Going backwards: from bytestream, to percent-encoding, to original string.
    return decodeURIComponent(atob(str).split('').map(function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
    }).join(''));
}

Above code can work, but it's very slow. If your input is a very large base64 string, for example 30,000 chars for a base64 html document. It will need lots of computation.

Here is my answer, use built-in TextDecoder, nearly 10x faster than above code for large input.

function decodeBase64(base64) {
    const text = atob(base64);
    const length = text.length;
    const bytes = new Uint8Array(length);
    for (let i = 0; i < length; i++) {
        bytes[i] = text.charCodeAt(i);
    }
    const decoder = new TextDecoder(); // default is utf-8
    return decoder.decode(bytes);
}

Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."

That being said, I own a copy of Burak's ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.

R doesn't have a concept of increment operator (as for example ++ in C). However, it is not difficult to implement one yourself, for example:

inc <- function(x)
{
 eval.parent(substitute(x <- x + 1))
}

In that case you would call

x <- 10
inc(x)

However, it introduces function call overhead, so it's slower than typing x <- x + 1 yourself. If I'm not mistaken increment operator was introduced to make job for compiler easier, as it could convert the code to those machine language instructions directly.

Most of these answers are wrong due to the failure to use a locale based comparison for sorting. Look at localizedStandardCompare()

Just wrap it around then.

<?php        
    if ( ($cart->count_product) > 0) 
    { 
        echo "<div class='my_class'>";
        print $cart->count_product; 
        echo "</div>";
    }

?>

You could declare a table variable (Declaring a variable of type table):

declare @MonthsSale table(monthnr int)
insert into @MonthsSale (monthnr) values (1)
insert into @MonthsSale (monthnr) values (2)
....

You can add extra columns as you like:

declare @MonthsSale table(monthnr int, totalsales tinyint)

You can update the table variable like any other table:

update m
set m.TotalSales = sum(s.SalesValue)
from @MonthsSale m
left join Sales s on month(s.SalesDt) = m.MonthNr

• Remember that you (the programmer) has to secure all parts, but the attacker only has to succeed in finding one kink in your armour.

On my case it was casing from Limits on Table Column Count and Row Size and doing changes described in this answer saved my day.

1. Add the following to the my.cnf file under [mysqld] section.

   innodb_file_per_table
   innodb_file_format = Barracuda

2. ALTER the table to use ROW_FORMAT=COMPRESSED.

   ALTER TABLE table_name

One can also use std::valarray<T> like this

#include<iostream>
#include<vector>
#include<valarray>

int main()
{
    std::vector<int> seq{ 1,2,3,4,5,6,7,8,9,10 };
    std::valarray<int> seq_add{ seq.data(), seq.size() };
    std::cout << "sum = " << seq_add.sum() << "\n";

    return 0;
}

Some may not find this way efficient since the size of valarray needs to be as big as the size of the vector and initializing valarray will also take time.

In that case, don't use it and take it as yet another way of summing up the sequence.

To start the process with parameters, you can use following code:

string filename = Path.Combine(cPath,"HHTCtrlp.exe");
var proc = System.Diagnostics.Process.Start(filename, cParams);

To kill/exit the program again, you can use following code:

proc.CloseMainWindow(); 
proc.Close();

fflush() only flushes the buffering added by the stdio fopen() layer, as managed by the FILE * object. The underlying file itself, as seen by the kernel, is not buffered at this level. This means that writes that bypass the FILE * layer, using fileno() and a raw write(), are also not buffered in a way that fflush() would flush.

As others have pointed out, try not mixing the two. If you need to use "raw" I/O functions such as ioctl(), then open() the file yourself directly, without using fopen<() and friends from stdio.

Non of the provided answers are correct.

You CAN set style programatically.

Short answer is take a look at http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/5.1.1_r1/android/content/Context.java#435

Long answer. Here's my snippet to set custom defined style programatically to your view:

1) Create a style in your styles.xml file

 <style name="MyStyle">
    <item name="customTextColor">#39445B</item>
    <item name="customDividerColor">#8D5AA8</item>
</style>

Do not forget to define your custom attributes in attrs.xml file

My attrsl.xml file:

<declare-styleable name="CustomWidget">
    <attr name="customTextColor" format="color" />
    <attr name="customDividerColor" format="color" />
</declare-styleable>

Notice you can use any name for your styleable (my CustomWidget)

Now lets set the style to the widget Programatically Here's My simple widget:

public class StyleableWidget extends LinearLayout {

private final StyleLoader styleLoader = new StyleLoader();

private TextView textView;
private View divider;

public StyleableWidget(Context context) {
    super(context);
    init();
}

private void init() {
    inflate(getContext(), R.layout.widget_styleable, this);
    textView = (TextView) findViewById(R.id.text_view);
    divider = findViewById(R.id.divider);
    setOrientation(VERTICAL);
}

protected void apply(StyleLoader.StyleAttrs styleAttrs) {
    textView.setTextColor(styleAttrs.textColor);
    divider.setBackgroundColor(styleAttrs.dividerColor);
}

public void setStyle(@StyleRes int style) {
    apply(styleLoader.load(getContext(), style));
}
}

layout:

<TextView
    android:id="@+id/text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="22sp"
    android:layout_gravity="center"
    android:text="@string/styleble_title" />

<View
    android:id="@+id/divider"
    android:layout_width="match_parent"
    android:layout_height="1dp"/>

</merge>

And finally StyleLoader class implementation

public class StyleLoader {

public StyleLoader() {

}

public static class StyleAttrs {
    public int textColor;
    public int dividerColor;
}

public StyleAttrs load(Context context, @StyleRes int styleResId) {
    final TypedArray styledAttributes = context.obtainStyledAttributes(styleResId, R.styleable.CustomWidget);
    return load(styledAttributes);
}

@NonNull
private StyleAttrs load(TypedArray styledAttributes) {
    StyleAttrs styleAttrs = new StyleAttrs();
    try {
        styleAttrs.textColor = styledAttributes.getColor(R.styleable.CustomWidget_customTextColor, 0);
        styleAttrs.dividerColor = styledAttributes.getColor(R.styleable.CustomWidget_customDividerColor, 0);
    } finally {
        styledAttributes.recycle();
    }
    return styleAttrs;
}
}

You can find fully working example at https://github.com/Defuera/SetStylableProgramatically

You can still unit test a void method by asserting that it had the appropriate side effect. In your method1 example, your unit test might look something like:

public void checkIfValidElementsWithDollarSign() {
    checkIfValidElement("$",19);
    assert ErrorFile.errorMessages.contains("There is a dollar sign in the specified parameter");
}

You will have to submit this data to the server somehow. I'm assuming that you don't want to do a full page reload every time a user clicks a link, so you'll have to user XHR (AJAX). If you are not using jQuery (or some other JS library) you can read this tutorial on how to do the XHR request "by hand".

Use below code for create notification for open activity. It works for me. For full code

 Intent myIntent = new Intent(context, DoSomething.class);
 PendingIntent pendingIntent = PendingIntent.getActivity(
        context, 
        0, 
        myIntent, 
        Intent.FLAG_ACTIVITY_NEW_TASK);

 myNotification = new NotificationCompat.Builder(context)
   .setContentTitle("Exercise of Notification!")
   .setContentText("Do Something...")
   .setTicker("Notification!")
   .setWhen(System.currentTimeMillis())
   .setContentIntent(pendingIntent)
   .setDefaults(Notification.DEFAULT_SOUND)
   .setAutoCancel(true)
   .setSmallIcon(R.drawable.ic_launcher)
   .build();

 notificationManager = 
   (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
 notificationManager.notify(MY_NOTIFICATION_ID, myNotification);

If you want to sum the digit of a number, one way to do it is using sum() + a generator expression:

sum(int(i) for i in str(155))

I modified a little your code using sum(), maybe you want to take a look at it:

birthday = raw_input("When is your birthday(mm/dd/yyyy)? ")
summ = sum(int(i) for i in birthday[0:2])
sumd = sum(int(i) for i in birthday[3:5])
sumy = sum(int(i) for i in birthday[6:10])
sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumln = sum(int(c) for c in str(sumall)))
print "Your lucky number is", sumln

Save the number of cents rather than dollars, and just do the format to dollars when you output it. That way you can use an integer which doesn't suffer from the precision issues.

stored value in DB is: 5XXXXXX [where x can be any digit]

You don't mention data types - if numeric, you'll likely have to use CAST/CONVERT to change the data type to [n]varchar.

Use:

WHERE CHARINDEX(column, '5') = 1
  AND CHARINDEX(column, '.') = 0 --to stop decimals if needed
  AND ISNUMERIC(column) = 1

References:

• CHARINDEX
• ISNUMERIC

i have also different cases like XXXX7XX for example, so it has to be generic.

Use:

WHERE PATINDEX('%7%', column) = 5
  AND CHARINDEX(column, '.') = 0 --to stop decimals if needed
  AND ISNUMERIC(column) = 1

References:

• PATINDEX

Regex Support

SQL Server 2000+ supports regex, but the catch is you have to create the UDF function in CLR before you have the ability. There are numerous articles providing example code if you google them. Once you have that in place, you can use:

• 5\d{6} for your first example
• \d{4}7\d{2} for your second example

For more info on regular expressions, I highly recommend this website.

Thread.State enum class and the new getState() API are provided for querying the execution state of a thread.

A thread can be in only one state at a given point in time. These states are virtual machine states which do not reflect any operating system thread states [NEW, RUNNABLE, BLOCKED, WAITING, TIMED_WAITING, TERMINATED].

enum Thread.State extends Enum implements Serializable, Comparable

• getState()^jdk5 - public State getState() {...} « Returns the state of this thread. This method is designed for use in monitoring of the system state, not for synchronization control.

• isAlive() - public final native boolean isAlive(); « Returns true if the thread upon which it is called is still alive, otherwise it returns false. A thread is alive if it has been started and has not yet died.

Sample Source Code's of classes java.lang.Thread and sun.misc.VM.

package java.lang;
public class Thread implements Runnable {
    public final native boolean isAlive();

    // Java thread status value zero corresponds to state "NEW" - 'not yet started'.

Recently I had a similar problem and solved it with this easy query:

SELECT
  (to_date(:p_to_date,'DD-MM-YYYY') - level + 1) AS day
FROM
  dual
CONNECT BY LEVEL <= (to_date(:p_to_date,'DD-MM-YYYY') - to_date(:p_from_date,'DD-MM-YYYY') + 1);

Example

SELECT
  (to_date('01-05-2015','DD-MM-YYYY') - level + 1) AS day
FROM
  dual
CONNECT BY LEVEL <= (to_date('01-05-2015','DD-MM-YYYY') - to_date('01-04-2015','DD-MM-YYYY') + 1);

Result

If it's reasonable to alter the original Map data structure to be serialized to better represent the actual value wanted to be serialized, that's probably a decent approach, which would possibly reduce the amount of Jackson configuration necessary. For example, just remove the null key entries, if possible, before calling Jackson. That said...

To suppress serializing Map entries with null values:

Before Jackson 2.9

you can still make use of WRITE_NULL_MAP_VALUES, but note that it's moved to SerializationFeature:

mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);

Since Jackson 2.9

The WRITE_NULL_MAP_VALUES is deprecated, you can use the below equivalent:

mapper.setDefaultPropertyInclusion(
   JsonInclude.Value.construct(Include.ALWAYS, Include.NON_NULL))

To suppress serializing properties with null values, you can configure the ObjectMapper directly, or make use of the @JsonInclude annotation:

mapper.setSerializationInclusion(Include.NON_NULL);

or:

@JsonInclude(Include.NON_NULL)
class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To handle null Map keys, some custom serialization is necessary, as best I understand.

A simple approach to serialize null keys as empty strings (including complete examples of the two previously mentioned configurations):

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import com.fasterxml.jackson.annotation.JsonInclude.Include;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.SerializerProvider;

public class JacksonFoo
{
  public static void main(String[] args) throws Exception
  {
    Map<String, Foo> foos = new HashMap<String, Foo>();
    foos.put("foo1", new Foo("foo1"));
    foos.put("foo2", new Foo(null));
    foos.put("foo3", null);
    foos.put(null, new Foo("foo4"));

    // System.out.println(new ObjectMapper().writeValueAsString(foos));
    // Exception: Null key for a Map not allowed in JSON (use a converting NullKeySerializer?)

    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);
    mapper.setSerializationInclusion(Include.NON_NULL);
    mapper.getSerializerProvider().setNullKeySerializer(new MyNullKeySerializer());
    System.out.println(mapper.writeValueAsString(foos));
    // output: 
    // {"":{"bar":"foo4"},"foo2":{},"foo1":{"bar":"foo1"}}
  }
}

class MyNullKeySerializer extends JsonSerializer<Object>
{
  @Override
  public void serialize(Object nullKey, JsonGenerator jsonGenerator, SerializerProvider unused) 
      throws IOException, JsonProcessingException
  {
    jsonGenerator.writeFieldName("");
  }
}

class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To suppress serializing Map entries with null keys, further custom serialization processing would be necessary.

The view-source url prefix trick didn't work for me using chrome on an iphone. There are apps I could have installed to do this I guess but for whatever reason I just preferred to do it myself rather than install 'yet another app'.

I found this nice quick tutorial for how to setup a bookmark on mobile safari that will automatically open the view source of a page: https://appletoolbox.com/2014/03/how-to-view-webpage-html-source-codes-on-ipad-iphone-no-app-required/

It worked flawlessly for me and now I have it set as a permanent bookmark any time I want, with no app installed.

Edit: There are basically 6 steps which should work for either Chrome or Safari. Instructions for Safari are:

1. Open Safari and browse to an arbitrary page.
2. Select the "Share" (or action") button in Safari (looks like a square with an arrow coming out of the top).
3. Select "Add Bookmark"
4. Delete the page title and replace it with something useful like "Show Page Source". Click Save.
5. Next browse to this exact Stack Overflow answer on your phone and copy the javascript code below to your phone clipboard (code credit: Rob Flaherty):

javascript:(function(){var a=window.open('about:blank').document;a.write('<!DOCTYPE html><html><head><title>Source of '+location.href+'</title><meta name="viewport" content="width=device-width" /></head><body></body></html>');a.close();var b=a.body.appendChild(a.createElement('pre'));b.style.overflow='auto';b.style.whiteSpace='pre-wrap';b.appendChild(a.createTextNode(document.documentElement.innerHTML))})();

6. Open the "Bookmarks" in Safari and opt to Edit the newly created Show Page Source bookmark. Delete whatever was previously saved in the Address field and instead paste in the Javascript code. Save it.
7. (Optional) Profit!

tools => fiddler options => connections there is a textarea with stuff to jump, delete LH from there

i have tried the best way and less code but may be it is little bit difficult to understand how i wrote my code but if you good at maths it is so easy

import java.util.Scanner;

class hours {

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    double s;


    System.out.println("how many second you have ");
    s =input.nextInt();



     double h=s/3600;
     int h2=(int)h;

     double h_h2=h-h2;
     double m=h_h2*60;
     int m1=(int)m;

     double m_m1=m-m1;
     double m_m1s=m_m1*60;






     System.out.println(h2+" hours:"+m1+" Minutes:"+Math.round(m_m1s)+" seconds");





}

}

more over it is accurate !

Search and replace

outline: thin dotted;

You have some special words from CMAKE, take a look:

if(${CMAKE_SYSTEM_NAME} STREQUAL "Linux")
    // do something for Linux
else
    // do something for other OS

In my case , aLengthMenu is not working. So i used this. And it is working.

jQuery('#dyntable3').dataTable({            
            oLanguage: {sLengthMenu: "<select>"+
            "<option value='100'>100</option>"+
            "<option value='200'>200</option>"+
            "<option value='300'>300</option>"+
            "<option value='-1'>All</option>"+
            "</select>"},
            "iDisplayLength": 100

        });

Thank you

mkdir -p "$d" && cp file "$d"

(there's no such option for cp).

use this one

//for getting length of object
 int length = jsonObject.length();

or

//for getting length of array
 int length = jsonArray.length();

I wrote this simple function just pass req.headers.cookie and cookie name

const getCookieByName =(cookies,name)=>{
    const arrOfCookies = cookies.split(' ')
    let yourCookie = null

    arrOfCookies.forEach(element => {
        if(element.includes(name)){
            yourCookie = element.replace(name+'=','')
        }
    });
    return yourCookie
}

This functionality is available from C# 4.0 - it was introduced in Visual Studio 2010. And you can use it in project for .NET 3.5. So there is no need to upgrade old projects in .NET 3.5 to .NET 4.0.

You have to just use Visual Studio 2010, but remember that it should compile to default language version (set it in project Properties->Buid->Advanced...)

This MSDN page has more information about optional parameters in VS 2010.

Use this instead of a for loop:

k = 1
while k <= c:
   #code
   k += 1

One option would be combining use of CASE..WHEN statement is redundant within an aggregation for MySQL Database, and considering the needed query generation dynamically along with getting proper column title for the result set as in the following code block :

SET @sql = NULL;

SELECT GROUP_CONCAT(
             CONCAT('SUM( `action` = ''', action, '''',pc0,' ) AS ',action,pc1)
       )
  INTO @sql
  FROM 
  ( 
   SELECT DISTINCT `action`, 
          IF(`pagecount` IS NULL,'',CONCAT('page',`pagecount`)) AS pc1,
          IF(`pagecount` IS NULL,'',CONCAT(' AND `pagecount` = ', pagecount, '')) AS pc0
     FROM `tab` 
    ORDER BY CONCAT(action,pc0) 
  ) t;

SET @sql = CONCAT('SELECT company_name,',@sql,' FROM `tab` GROUP BY company_name'); 
SELECT @sql; 

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Demo

This is a variation of something I learned several years back. Apparently, this is popular with C++ developers.

First off, I think I know why you want to break out of IF blocks. For me, I don't like a bunch of nested blocks because 1) it makes the code look messy and 2) it can be a pia to maintain if you have to move logic around.

Consider a do/while loop instead:

public void Method()
{
    bool something = true, something2 = false;

    do
    {
        if (!something) break;

        if (something2) break;

    } while (false);
}

The do/while loop is guaranteed to run only once just like an IF block thanks to the hardcoded false condition. When you want to exit early, just break.

In general

Asymptotic notation is something you can understand as: how do functions compare when zooming out? (A good way to test this is simply to use a tool like Desmos and play with your mouse wheel). In particular:

• f(n) ? o(n) means: at some point, the more you zoom out, the more f(n) will be dominated by n (it will progressively diverge from it).
• g(n) ? T(n) means: at some point, zooming out will not change how g(n) compare to n (if we remove ticks from the axis you couldn't tell the zoom level).

Finally h(n) ? O(n) means that function h can be in either of these two categories. It can either look a lot like n or it could be smaller and smaller than n when n increases. Basically, both f(n) and g(n) are also in O(n).

In computer science

In computer science, people will usually prove that a given algorithm admits both an upper O and a lower bound . When both bounds meet that means that we found an asymptotically optimal algorithm to solve that particular problem.

For example, if we prove that the complexity of an algorithm is both in O(n) and (n) it implies that its complexity is in T(n). That's the definition of T and it more or less translates to "asymptotically equal". Which also means that no algorithm can solve the given problem in o(n). Again, roughly saying "this problem can't be solved in less than n steps".

An upper bound of O(n) simply means that even in the worse case, the algorithm will terminate in at most n steps (ignoring all constant factors, both multiplicative and additive). A lower bound of (n) means on the opposite that we built some examples where the problem solved by this algorithm couldn't be solved in less than n steps (again ignoring multiplicative and additive constants). The number of steps is at most n and at least n so this problem complexity is "exactly n". Instead of saying "ignoring constant multiplicative/additive factor" every time we just write T(n) for short.

Another case that could cause this error is

>>> np.ndindex(np.random.rand(60,60))
TypeError: only integer scalar arrays can be converted to a scalar index

Using the actual shape will fix it.

>>> np.ndindex(np.random.rand(60,60).shape)
<numpy.ndindex object at 0x000001B887A98880>

func resizeImage(image: UIImage, newWidth: CGFloat) -> UIImage? {

    let scale = newWidth / image.size.width
    let newHeight = CGFloat(200.0)
    UIGraphicsBeginImageContext(CGSize(width: newWidth, height: newHeight))
    image.draw(in: CGRect(x: 0, y: 0, width: newWidth, height: newHeight))

    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

If you want to set the cursor after n character from right to left then you have to do like this.

edittext.setSelection(edittext.length()-n);

If edittext's text like

version<sub></sub>

and you want to move cursor at 6th position from right

Then it will move the cursor at-

    version<sub> </sub>
                ^

Well, its an easy way of doing some registry changes: I tried this on 2008 r2 and 2016 servers.

Things need to be done:

1. Create a text file "regedit.txt"
2. Paste the following code in it:

Windows Registry Editor Version 5.00 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\State\Machine\Scripts]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\State\Machine\Scripts\Shutdown] 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\Scripts\Shutdown]     

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\State\Machine\Scripts\Shutdown\0]  
"GPO-ID"="LocalGPO"    
"SOM-ID"="Local"    
"FileSysPath"="C:\\Windows\\System32\\GroupPolicy\\Machine"    
"DisplayName"="Local Group Policy"    
"GPOName"="Local Group Policy"    

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\State\Machine\Scripts\Shutdown\0\0]    
"Script"="terminate_script.bat"    
"Parameters"=""    
"ExecTime"=hex(b):00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00

"DisplayName"="Local Group Policy"    
"GPOName"="Local Group Policy"

"ExecTime"=hex(b):00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00

3. Save this file as regedit.reg extension

4. Run it on any command line using below command:

   regedit.exe /s regedit.reg
   

BaseWebApi.cs

public abstract class BaseWebApi
{
    //Inject HttpClient from Ninject

    }

    public async Task<TOut> PostAsync<TOut>(string method, object param, Dictionary<string, string> headers, HttpMethod httpMethod)
    {
        //Set url

        HttpResponseMessage response;
        using (var request = new HttpRequestMessage(httpMethod, url))
        {
            AddBody(param, request);
            AddHeaders(request, headers);
            response = await _httpClient.SendAsync(request, cancellationToken);
        }

        if(response.IsSuccessStatusCode)
        {
             return await response.Content.ReadAsAsync<TOut>();
        }
        //Exception handling
    }

    private void AddHeaders(HttpRequestMessage request, Dictionary<string, string> headers)
    {
        request.Headers.Accept.Clear();
        request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        if (headers == null) return;

        foreach (var header in headers)
        {
            request.Headers.Add(header.Key, header.Value);
        }
    }

    private static void AddBody(object param, HttpRequestMessage request)
    {
        if (param != null)
        {
            var content = JsonConvert.SerializeObject(param);
            request.Content = new StringContent(content);
            request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
        }
    }

SubWebApi.cs

public sealed class SubWebApi : BaseWebApi
{
    public SubWebApi(HttpClient httpClient) : base(httpClient) {}

    public async Task<StuffResponse> GetStuffAsync(int cvr)
    {
        var method = "get/stuff";
        var request = new StuffRequest 
        {
            query = "GiveMeStuff"
        }
        return await PostAsync<StuffResponse>(method, request, GetHeaders(), HttpMethod.Post);
    }
    private Dictionary<string, string> GetHeaders()
    {
        var headers = new Dictionary<string, string>();
        var basicAuth = GetBasicAuth();
        headers.Add("Authorization", basicAuth);
        return headers;
    }

    private string GetBasicAuth()
    {
        var byteArray = Encoding.ASCII.GetBytes($"{SystemSettings.Username}:{SystemSettings.Password}");
        var authString = Convert.ToBase64String(byteArray);
        return $"Basic {authString}";
    }
}

I was able to import the module within the function (only) that would require the objects from this module:

def my_func():
    import Foo
    foo_instance = Foo()

var Foo = function(){
    document.getElementById( "a" ).setAttribute( "onClick", "javascript: Boo();" );
}

var Boo = function(){
    alert("test");
}

Content inside a <div class='html-content'>....</div> can be downloaded as pdf with styles using jspdf & html2canvas.

You need to refer both js libraries,

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.min.js"></script>
<script type="text/javascript" src="https://html2canvas.hertzen.com/dist/html2canvas.js"></script>

Then call below function,

//Create PDf from HTML...
function CreatePDFfromHTML() {
    var HTML_Width = $(".html-content").width();
    var HTML_Height = $(".html-content").height();
    var top_left_margin = 15;
    var PDF_Width = HTML_Width + (top_left_margin * 2);
    var PDF_Height = (PDF_Width * 1.5) + (top_left_margin * 2);
    var canvas_image_width = HTML_Width;
    var canvas_image_height = HTML_Height;

    var totalPDFPages = Math.ceil(HTML_Height / PDF_Height) - 1;

    html2canvas($(".html-content")[0]).then(function (canvas) {
        var imgData = canvas.toDataURL("image/jpeg", 1.0);
        var pdf = new jsPDF('p', 'pt', [PDF_Width, PDF_Height]);
        pdf.addImage(imgData, 'JPG', top_left_margin, top_left_margin, canvas_image_width, canvas_image_height);
        for (var i = 1; i <= totalPDFPages; i++) { 
            pdf.addPage(PDF_Width, PDF_Height);
            pdf.addImage(imgData, 'JPG', top_left_margin, -(PDF_Height*i)+(top_left_margin*4),canvas_image_width,canvas_image_height);
        }
        pdf.save("Your_PDF_Name.pdf");
        $(".html-content").hide();
    });
}

May be this will help someone.

Yes. I recommend you check out Kimberly Tripp's articles on indexing.

If an index is "covering", then there is no need to use anything but the index. In SQL Server 2005, you can also add additional columns to the index that are not part of the key which can eliminate trips to the rest of the row.

Having multiple indexes, each on a single column may mean that only one index gets used at all - you will have to refer to the execution plan to see what effects different indexing schemes offer.

You can also use the tuning wizard to help determine what indexes would make a given query or workload perform the best.

As of September 2016 this addon is the best to disable CORS: https://github.com/fredericlb/Force-CORS/releases

In the options panel you can configure which header to inject and specific website to have it enabled automatically.

Run the following code:

du -sh /var/log/mysql

Perhaps mysql binary logs filled the memory, If so, follow the removal of old logs and restart the server. Also add in my.cnf:

expire_logs_days = 3

EDIT If you are using SQL Server 2012+ you can use throw clause. Here are the details.

"Not ASCII (neither's ?/?)" needs qualification.

While these characters are not defined in the American Standard Code for Information Interchange as glyphs, their codes WERE commonly used to give a graphical presentation for ASCII codes 24 and 25 (hex 18 and 19, CANcel and EM:End of Medium). Code page 437 (called Extended ASCII by IBM, includes the numeric codes 128 to 255) defined the use of these glyphs as ASCII codes and the ubiquity of these conventions permeated the industry as seen by their deployment as standards by leading companies such as HP, particularly for printers, and IBM, particularly for microcomputers starting with the original PC.

Just as the use of the ASCII codes for CAN and EM was relatively obsolete at the time, justifying their use as glyphs, so has the passage of time made the use of the codes as glyphs obsolete by the current use of UNICODE conventions.

It should be emphasized that the extensions to ASCII made by IBM in Extended ASCII, included not only a larger numeric set for numeric codes 128 to 255, but also extended the use of some numeric control codes, in the ASCII range 0 to 32, from just media transmission control protocols to include glyphs. It is often assumed, incorrectly, that the first 0 to 128 were not "extended" and that IBM was using the glyphs of conventional ASCII for this range. This error is also perpetrated in one of the previous references. This error became so pervasive that it colloquially redefined ASCII subliminally.

Another modelling tool for Java is (my) website GitUML. Generate UML diagrams from Java or Python code stored in GitHub repositories.

One key idea with GitUML is to address one of the problems with "documentation": that diagrams are always out of date. With GitUML, diagrams automatically update when you push code using git.

Browse through community UML diagrams, there are some Java design patterns there. Surf through popular GitHub repositories and visualise the architectures and patterns in them.

Create diagrams using point and click. There is no drag drop editor, just click on the classes in the repository tree that you want to visualise:

The underlying technology is PlantUML based, which means you can refine your diagrams with additional PlantUML markup.

Here's a function that finds the dictionary's index position if it exists.

dicts = [{'id':'1234','name':'Jason'},
         {'id':'2345','name':'Tom'},
         {'id':'3456','name':'Art'}]

def find_index(dicts, key, value):
    class Null: pass
    for i, d in enumerate(dicts):
        if d.get(key, Null) == value:
            return i
    else:
        raise ValueError('no dict with the key and value combination found')

print find_index(dicts, 'name', 'Tom')
# 1
find_index(dicts, 'name', 'Ensnare')
# ValueError: no dict with the key and value combination found

Example as per doc

@Component({
  selector: 'date-pipe',
  template: `<div>
    <p>Today is {{today | date}}</p>
    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
    <p>The time is {{today | date:'jmZ'}}</p>
  </div>`
})
export class DatePipeComponent {
  today: number = Date.now();
}

Template

{{ dateObj | date }}               // output is 'Jun 15, 2015'
{{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
{{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
{{ dateObj | date:'mmss' }}        // output is '43:11'
{{dateObj  | date: 'dd/MM/yyyy'}} // 15/06/2015

To Use in your component.

@Injectable()
import { DatePipe } from '@angular/common';
class MyService {

  constructor(private datePipe: DatePipe) {}

  transformDate(date) {
    this.datePipe.transform(myDate, 'yyyy-MM-dd'); //whatever format you need. 
  }
}

In your app.module.ts

providers: [DatePipe,...] 

all you have to do is use this service now.

if I select the second row -

 Dim jason As DataRowView


    jason = dg1.SelectedItem

    noteText.Text = jason.Item(0).ToString()

noteText will be 646. This is VB, but you get it.

Smart pointers will clean themselves up after they go out of scope (thereby removing fear of most memory leaks). Shared pointers are smart pointers that keep a count of how many instances of the pointer exist, and only clean up the memory when the count reaches zero. In general, only use shared pointers (but be sure to use the correct kind--there is a different one for arrays). They have a lot to do with RAII.

One line solution. However it works for one column only.

df.loc[pandas.isna(df["b"]), :].index

Update your get_categories() method to return the total (wrapped in an observable):

// Note that .subscribe() is gone and I've added a return.
get_categories(number) {
  return this.http.post( url, body, {headers: headers, withCredentials:true})
    .map(response => response.json());
}

In search_categories(), you can subscribe the observable returned by get_categories() (or you could keep transforming it by chaining more RxJS operators):

// send_categories() is now called after get_categories().
search_categories() {
  this.get_categories(1)
    // The .subscribe() method accepts 3 callbacks
    .subscribe(
      // The 1st callback handles the data emitted by the observable.
      // In your case, it's the JSON data extracted from the response.
      // That's where you'll find your total property.
      (jsonData) => {
        this.send_categories(jsonData.total);
      },
      // The 2nd callback handles errors.
      (err) => console.error(err),
      // The 3rd callback handles the "complete" event.
      () => console.log("observable complete")
    );
}

Note that you only subscribe ONCE, at the end.

Like I said in the comments, the .subscribe() method of any observable accepts 3 callbacks like this:

obs.subscribe(
  nextCallback,
  errorCallback,
  completeCallback
);

They must be passed in this order. You don't have to pass all three. Many times only the nextCallback is implemented:

obs.subscribe(nextCallback);

I had the same error:
"Syntax error, unrecognized expression: // "
It is known bug at JQuery, so i needed to think on workaround solution,
What I did is:
I changed "script" tag to "div"
and added at angular this code
and the error is gone...

app.run(['$templateCache', function($templateCache) {
    var url = "survey-input.html";
    content = angular.element(document.getElementById(url)).html()
    $templateCache.put(url, content);
}]);

I solved it for Intellij Idea I facing this problem Althouh , I change a lot of place to resolve problem.I found a solution for me .Right click your project ,You will see Maven ,after that press Generate Sources And Update Folders and ReImport

It is done.

This is possible with window.localStorage or window.sessionStorage. The difference is that sessionStorage lasts for as long as the browser stays open, localStorage survives past browser restarts. The persistence applies to the entire web site not just a single page of it.

When you need to set a variable that should be reflected in the next page(s), use:

var someVarName = "value";
localStorage.setItem("someVarKey", someVarName);

And in any page (like when the page has loaded), get it like:

var someVarName = localStorage.getItem("someVarKey");

.getItem() will return null if no value stored, or the value stored.

Note that only string values can be stored in this storage, but this can be overcome by using JSON.stringify and JSON.parse. Technically, whenever you call .setItem(), it will call .toString() on the value and store that.

MDN's DOM storage guide (linked below), has workarounds/polyfills, that end up falling back to stuff like cookies, if localStorage isn't available.

It wouldn't be a bad idea to use an existing, or create your own mini library, that abstracts the ability to save any data type (like object literals, arrays, etc.).

I also met the case to use both python2 and python3 on my Windows machine. Here's how i resolved it:

1. download python2x and python3x, installed them.
2. add C:\Python35;C:\Python35\Scripts;C:\Python27;C:\Python27\Scripts to environment variable PATH.
3. Go to C:\Python35 to rename python.exe to python3.exe, also to C:\Python27, rename python.exe to python2.exe.
4. restart your command window.
5. type python2 scriptname.py, or python3 scriptname.py in command line to switch the version you like.

try to do this in the behind code

   public diagboxclass()
   {
         List<object> list = new List<object>();
         list = GetObjectList();
         Imported.ItemsSource = null;
         Imported.ItemsSource = list;
   }

Also be sure your list is effectively populated and as mentioned by Blindmeis, never use words that already are given a function in c#.

Objects

There is no benefit to using new Object(); - whereas {}; can make your code more compact, and more readable.

For defining empty objects they're technically the same. The {} syntax is shorter, neater (less Java-ish), and allows you to instantly populate the object inline - like so:

var myObject = {
        title:  'Frog',
        url:    '/img/picture.jpg',
        width:  300,
        height: 200
      };

Arrays

For arrays, there's similarly almost no benefit to ever using new Array(); over []; - with one minor exception:

var emptyArray = new Array(100);

creates a 100 item long array with all slots containing undefined - which may be nice/useful in certain situations (such as (new Array(9)).join('Na-Na ') + 'Batman!').

My recommendation

1. Never use new Object(); - it's clunkier than {}; and looks silly.
2. Always use []; - except when you need to quickly create an "empty" array with a predefined length.

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

SELECT owner, directory_name, directory_path
  FROM all_directories

Better late than never. Your original code used enumerate(), but you only used the i index to check if it's the last item in a list. Here's an simpler alternative (if you don't need enumerate()) using negative indexing:

for data in data_list:
    code_that_is_done_for_every_element
    if data != data_list[-1]:
        code_that_is_done_between_elements

if data != data_list[-1] checks if the current item in the iteration is NOT the last item in the list.

Hope this helps, even nearly 11 years later.

Have you tried using Firebug to inspect the rendered HTML, and to see exactly what css is being applied to the various elements? That should pick up css errors like the ones mentioned above, and you can see what styles are being inherited and from where - it is an invaluable too in any css debugging.

Collation is what you need:

db.collectionName.find().sort({PartnerID: 1}).collation({locale: "en_US", numericOrdering: true})

Interestingly I checked this on an app of mine and I got the same error.

I spent a while checking through headers to see if there was anything undef'ing the _USE_MATH_DEFINES and found nothing.

So I moved the

#define _USE_MATH_DEFINES
#include <cmath>

to be the first thing in my file (I don't use PCHs so if you are you will have to have it after the #include "stdafx.h") and suddenly it compile perfectly.

Try moving it higher up the page. Totally unsure as to why this would cause issues though.

Edit: Figured it out. The #include <math.h> occurs within cmath's header guards. This means that something higher up the list of #includes is including cmath without the #define specified. math.h is specifically designed so that you can include it again with that define now changed to add M_PI etc. This is NOT the case with cmath. So you need to make sure you #define _USE_MATH_DEFINES before you include anything else. Hope that clears it up for you :)

Failing that just include math.h you are using non-standard C/C++ as already pointed out :)

Edit 2: Or as David points out in the comments just make yourself a constant that defines the value and you have something more portable anyway :)

public static Integer valueOf(String s)

1. The argument is interpreted as representing a signed decimal integer, exactly as if the argument were given to the parseInt(java.lang.String) method.

2. The result is an Integer object that represents the integer value specified by the string.

3. In other words, this method returns an Integer object equal to the value of: new Integer(Integer.parseInt(s))

DataNucleus JPA that I use also has a way of doing this in its docs. No need for Spring, or ugly implementation of PersistenceUnitInfo.

Simply do as follows

import org.datanucleus.metadata.PersistenceUnitMetaData;
import org.datanucleus.api.jpa.JPAEntityManagerFactory;

PersistenceUnitMetaData pumd = new PersistenceUnitMetaData("dynamic-unit", "RESOURCE_LOCAL", null);
pumd.addClassName("mydomain.test.A");
pumd.setExcludeUnlistedClasses();
pumd.addProperty("javax.persistence.jdbc.url", "jdbc:h2:mem:nucleus");
pumd.addProperty("javax.persistence.jdbc.user", "sa");
pumd.addProperty("javax.persistence.jdbc.password", "");
pumd.addProperty("datanucleus.schema.autoCreateAll", "true");

EntityManagerFactory emf = new JPAEntityManagerFactory(pumd, null);

Roll your own e.g.

function syncJSON(i_url, callback) {
  $.ajax({
    type: "POST",
    async: false,
    url: i_url,
    contentType: "application/json",
    dataType: "json",
    success: function (msg) { callback(msg) },
    error: function (msg) { alert('error : ' + msg.d); }
  });
}

syncJSON("/pathToYourResouce", function (msg) {
   console.log(msg);
})

I had to set

C:\ProgramData\MySQL\MySQL Server 8.0/my.ini  secure-file-priv=""

When I commented line with secure-file-priv, secure-file-priv was null and I couldn't download data.

You can also do this by passing function with onclick event

<a onclick="getColor(this);" color="red">

<script type="text/javascript">

function getColor(el)
{
     color = $(el).attr('color');
     alert(color);
}

</script> 

Use this code where str is your JSON string:

NSError *err = nil;
NSArray *arr = 
 [NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] 
                                 options:NSJSONReadingMutableContainers 
                                   error:&err];
// access the dictionaries
NSMutableDictionary *dict = arr[0];
for (NSMutableDictionary *dictionary in arr) {
  // do something using dictionary
}

Flex layout modes are not (fully) natively supported in IE yet. IE10 implements the "tween" version of the spec which is not fully recent, but still works.

https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes

This CSS-Tricks article has some advice on cross-browser use of flexbox (including IE): http://css-tricks.com/using-flexbox/

edit: after a bit more research, IE10 flexbox layout mode implemented current to the March 2012 W3C draft spec: http://www.w3.org/TR/2012/WD-css3-flexbox-20120322/

The most current draft is a year or so more recent: http://dev.w3.org/csswg/css-flexbox/

Don't forget that some numbers will repeat! so you need to do something like....

my totalQuestions was 47.

func getRandomNumbers(totalQuestions:Int) -> NSMutableArray
{

    var arrayOfRandomQuestions: [Int] = []

    print("arraySizeRequired = 40")
    print("totalQuestions = \(totalQuestions)")

    //This will output a 40 random numbers between 0 and totalQuestions (47)
    while arrayOfRandomQuestions.count < 40
    {

        let limit: UInt32 = UInt32(totalQuestions)

        let theRandomNumber = (Int(arc4random_uniform(limit)))

            if arrayOfRandomQuestions.contains(theRandomNumber)
            {
                print("ping")

            }
            else
            {
            //item not found
                arrayOfRandomQuestions.append(theRandomNumber)
            }

    }

    print("Random Number set = \(arrayOfRandomQuestions)")
    print("arrayOutputCount = \(arrayOfRandomQuestions.count)")


    return arrayOfRandomQuestions as! NSMutableArray

}

array.length will tell you how many elements are in an array

For anyone interested to implement a DropDown of custom class you can follow the bellow steps.

1. Suppose you have a class called Language with the following code and a static method which returns a List<Language>

   class Language {
     final int id;
     final String name;
     final String languageCode;
   
     const Language(this.id, this.name, this.languageCode);
   
   
   }
   
    const List<Language> getLanguages = <Language>[
           Language(1, 'English', 'en'),
           Language(2, '?????', 'fa'),
           Language(3, '????', 'ps'),
        ];
   

2. Anywhere you want to implement a DropDown you can import the Language class first use it as follow

       DropdownButton(
           underline: SizedBox(),
           icon: Icon(
                       Icons.language,
                       color: Colors.white,
                       ),
           items: getLanguages.map((Language lang) {
           return new DropdownMenuItem<String>(
                           value: lang.languageCode,
                           child: new Text(lang.name),
                         );
                       }).toList(),
   
           onChanged: (val) {
                         print(val);
                      },
         )
   

How do I link the main_folder to the test_container folder present inside the docker container?

Your command below is correct, unless your on a mac using boot2docker(depending on future updates) in which case you may find the folder empty. See mattes answer for a tutorial on correcting this.

docker run -d -v /Users/kishore/main_folder:/test_container k3_s3:latest

I need to make this run automatically, how to do that without really using the run -d -v command.

You can't really get away from using these commands, they are intrinsic to the way docker works. You would be best off putting them into a shell script to save you writing them out repeatedly.

What happens if boot2docker crashes? Where are the docker files stored?

If you manage to use the -v arg and reference your host machine then the files will be safe on your host.

If you've used 'docker build -t myimage .' with a Dockerfile then your files will be baked into the image.

Your docker images, i believe, are stored in the boot2docker-vm. I found this out when my images disappeared when i delete the vm from VirtualBox. (Note, i don't know how Virtualbox works, so the images might be still hidden somewhere else, just not visible to docker).

while(something.hasnext())
do something...
   if(contains something to process){
      do something...
      break;
   }
}

Just use the break statement;

For eg:this just prints "Breaking..."

while (true) {
     if (true) {
         System.out.println("Breaking...");
         break;
     }
     System.out.println("Did this print?");
}

Hi here is how i did it in one Project :

     @Html.DropDownListFor(model => model.MyOption,                
                  new List<SelectListItem> { 
                       new SelectListItem { Value = "0" , Text = "Option A" },
                       new SelectListItem { Value = "1" , Text = "Option B" },
                       new SelectListItem { Value = "2" , Text = "Option C" }
                    },
                  new { @class="myselect"})

I hope it helps Somebody. Thanks

It's still an attribute. Setting it to:

<input type="button" name=myButton value="disable" disabled="disabled">

... is valid.

I did also stumble upon this error. In my case the problem was I was using JRE6, with support for TLS1.0. The server only supported TLS1.2, so this error was thrown.

1. You should add L: long i = 12345678910L;.
2. Yes.

BTW: it doesn't have to be an upper case L, but lower case is confused with 1 many times :).

In Eclipse you can set a VM argument to:

-Dlog4j.configuration=file:///${workspace_loc:/MyProject/log4j-full-debug.properties}

I also needed build-essential installed:

sudo apt-get install build-essential

Try vbCrLf.

For example:

TextBox1.text = "line_one" & vbCrLf & "line_two"

The provided answers are the best solution in your case, and they are what I do as well, but if your text is printed by a function or class method you could do the same as in Javascript as well

function hello(){
echo 'HELLO';
}
$print = true;
$print && hello();

One way to get around this is to use implicit casting:

bool DoesEntityExist<T>(T entity, Guid guid, ITransaction transaction) where T : IGloballyIdentifiable;

calling it like so:

DoesEntityExist(entity, entityGuid, transaction);

Going a step further, you can turn it into an extension method (it will need to be declared in a static class):

static bool DoesEntityExist<T>(this T entity, Guid guid, ITransaction transaction) where T : IGloballyIdentifiable;

calling as so:

entity.DoesEntityExist(entityGuid, transaction);

There are some excellent points here and I'm going to add another one in case someones' path crosses here.

Thrift gives you an option to choose between thrift-binary and thrift-compact (de)serializer, thrift-binary will have an excellent performance but bigger packet size, while thrift-compact will give you good compression but needs more processing power. This is handy because you can always switch between these two modes as easily as changing a line of code (heck, even make it configurable). So if you are not sure how much your application should be optimized for packet size or in processing power, thrift can be an interesting choice.

PS: See this excellent benchmark project by thekvs which compares many serializers including thrift-binary, thrift-compact, and protobuf: https://github.com/thekvs/cpp-serializers

PS: There is another serializer named YAS which gives this option too but it is schema-less see the link above.

The solution provided by @dex worked for me. But I want to add something else that also worked for me: Use

let UserSchema = new Schema({
   username: {
     type: String
   },
   events: [{
     type: ObjectId,
     ref: 'Event' // Reference to some EventSchema
   }]
})

if what you want to create is an Array reference. But if what you want is an Object reference, which is what I think you might be looking for anyway, remove the brackets from the value prop, like this:

let UserSchema = new Schema({
   username: {
     type: String
   },
   events: {
     type: ObjectId,
     ref: 'Event' // Reference to some EventSchema
   }
})

Look at the 2 snippets well. In the second case, the value prop of key events does not have brackets over the object def.

Or you could just add some content to the div and use inline-table

On Ubuntu, you can simply install the chromium-chromedriver package:

apt install chromium-chromedriver

Be aware that this also installs an outdated Selenium version. To install the latest Selenium:

pip install selenium

In case you have space in your path, wrap it in double quotes:

$ git clone "//serverName/New Folder/Target" f1/

Instead of adding File, add class. File->New->Class. That fixed my issue.

var from = $("#datepicker").val(); 
var f = $.datepicker.parseDate("d-m-Y", from);

I had the same problem It happens because files can't contain special characters like ":", "?", ">" and etc. You should replace these files by using replace() function:

filename = filename.replace("special character to replace", "-")

This will work:

>>> t = [1,1,2,2,3,3,4,5]
>>> print list(set(t))
[1,2,3,4,5]

However, if you have used "list" or "set" as a variable name you will get the:

TypeError: 'set' object is not callable

eg:

>>> set = [1,1,2,2,3,3,4,5]
>>> print list(set(set))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable

Same error will occur if you have used "list" as a variable name.

If you receive multiple entries the correct method is called lists.

    Word_relation::select('word_two')->where('word_one', $word_id)->lists('word_one')->toArray();

This will print out the query:

$query = "SELECT order_date, no_of_items, shipping_charge, SUM(total_order_amount) as test FROM `orders` WHERE DATE(`order_date`) = DATE(NOW()) GROUP BY DATE(`order_date`)";

$dave= mysql_query($query) or die(mysql_error());
print $query;

This will print out the results:

$query = "SELECT order_date, no_of_items, shipping_charge, SUM(total_order_amount) as test FROM `orders` WHERE DATE(`order_date`) = DATE(NOW()) GROUP BY DATE(`order_date`)";

$dave= mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_assoc($dave)){
    foreach($row as $cname => $cvalue){
        print "$cname: $cvalue\t";
    }
    print "\r\n";
}

If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes. You set request header Content-Type: multipart/form-data; boundary=HereGoes. Then this should be a valid request body:

--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json

{"foo": "bar"}
--HereGoes
Content-Disposition: form-data; name="photo"
Content-Type: image/jpeg
Content-Transfer-Encoding: base64

One option is to use Python's slicing and indexing features to logically evaluate the places where your condition holds and overwrite the data there.

Assuming you can load your data directly into pandas with pandas.read_csv then the following code might be helpful for you.

import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"

As mentioned in the comments, you can also do the assignment to both columns in one shot:

df.loc[df.ID == 103, ['FirstName', 'LastName']] = 'Matt', 'Jones'

Note that you'll need pandas version 0.11 or newer to make use of loc for overwrite assignment operations.

Another way to do it is to use what is called chained assignment. The behavior of this is less stable and so it is not considered the best solution (it is explicitly discouraged in the docs), but it is useful to know about:

import pandas
df = pandas.read_csv("test.csv")
df['FirstName'][df.ID == 103] = "Matt"
df['LastName'][df.ID == 103] = "Jones"

jQuery is not needed, use simple javascript:

document.domain

You should use an Android emulator with the same api level as the compileSdkVersion. In your case you should use Android emulator with api level 21.

Here is the boolean based styling in JSX syntax:

style={{display: this.state.isShowing ? "inherit" : "none"}}

You can do it like this,

<input type="text" name="name" value="<?php echo $name;?>" />

But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.

<input type="text" name="name" value="<?php echo htmlspecialchars($name);?>" />

foreach my $arg (@ARGV) {
    print $arg, "\n";
}

will print each argument.

You can add any extension (in Wamp and Xampp servers) by removing the semi-colon (;)

subprocess.Popen() is strict super-set of os.system().

Python decorator is like a wrapper of a function or a class. It’s still too conceptual.

def function_decorator(func):
    def wrapped_func():
        # Do something before the function is executed
        func()
        # Do something after the function has been executed
    return wrapped_func

The above code is a definition of a decorator that decorates a function. function_decorator is the name of the decorator.

wrapped_func is the name of the inner function, which is actually only used in this decorator definition. func is the function that is being decorated. In the inner function wrapped_func, we can do whatever before and after the func is called. After the decorator is defined, we simply use it as follows.

@function_decorator
def func():
    pass

Then, whenever we call the function func, the behaviours we’ve defined in the decorator will also be executed.

EXAMPLE :

from functools import wraps

def mydecorator(f):
    @wraps(f)
    def wrapped(*args, **kwargs):
        print "Before decorated function"
        r = f(*args, **kwargs)
        print "After decorated function"
        return r
    return wrapped

@mydecorator
def myfunc(myarg):
    print "my function", myarg
    return "return value"

r = myfunc('asdf')
print r

Output :

    Before decorated function
    my function asdf
    After decorated function
    return value

If you know all your 21 characters in advance you can write them all as one String and then check it like this:

char wanted = 'x';
String candidates = "abcdefghij...";
boolean hit = candidates.indexOf(wanted) >= 0;

I think this is the shortest way.

OK turns out what you really want is this: http://inputsimulator.codeplex.com/

Which has done all the hard work of exposing the Win32 SendInput methods to C#. This allows you to directly send the windows key. This is tested and works:

InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.VK_E);

Note however that in some cases you want to specifically send the key to the application (such as ALT+F4), in which case use the Form library method. In others, you want to send it to the OS in general, use the above.

Old

Keeping this here for reference, it will not work in all operating systems, and will not always behave how you want. Note that you're trying to send these key strokes to the app, and the OS usually intercepts them early. In the case of Windows 7 and Vista, too early (before the E is sent).

SendWait("^({ESC}E)") or Send("^({ESC}E)")

Note from here: http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx

To specify that any combination of SHIFT, CTRL, and ALT should be held down while several other keys are pressed, enclose the code for those keys in parentheses. For example, to specify to hold down SHIFT while E and C are pressed, use "+(EC)". To specify to hold down SHIFT while E is pressed, followed by C without SHIFT, use "+EC".

Note that since you want ESC and (say) E pressed at the same time, you need to enclose them in brackets.

I'm chiming in with a detailed answer that specifically addresses Apache HttpClient 4.0.1. I'm using this HttpClient version, since it's provided by WAS v8.0, and I need to use that provided HttpClient within Apache Wink v1.1.1, also provided by WAS v8.0, to make some NTLM-authenticated REST calls to Sharepoint.

To quote Oleg Kalnichevski on the Apache HttpClient mailing list:

Pretty much all this code is not necessary. (1) HttpClient will automatically release the underlying connection as long as the entity content is consumed to the end of stream; (2) HttpClient will automatically release the underlying connection on any I/O exception thrown while reading the response content. No special processing is required in such as case.

In fact, this is perfectly sufficient to ensure proper release of resources:

HttpResponse rsp = httpclient.execute(target, req); 
HttpEntity entity = rsp.getEntity(); 
if (entity != null) {
     InputStream instream = entity.getContent();
     try {
         // process content
     } finally {
         instream.close();
         // entity.consumeContent() would also do
     } 
}

That is it.

CONNECTION_REFUSED is standard when the port is closed, but it could be rejected because SSL is failing authentication (one of a billion reasons). Did you configure SSL with Ratchet? (Apache is bypassed) Did you try without SSL in JavaScript?

I don't think Ratchet has built-in support for SSL. But even if it does you'll want to try the ws:// protocol first; it's a lot simpler, easier to debug, and closer to telnet. Chrome or the socket service may also be generating the REFUSED error if the service doesn't support SSL (because you explicitly requested SSL).

However the refused message is likely a server side problem, (usually port closed).

In case you're interested in a solution using Java 7 and NIO.2, it could go like this:

private static class DirectoriesFilter implements Filter<Path> {
    @Override
    public boolean accept(Path entry) throws IOException {
        return Files.isDirectory(entry);
    }
}

try (DirectoryStream<Path> ds = Files.newDirectoryStream(FileSystems.getDefault().getPath(root), new DirectoriesFilter())) {
        for (Path p : ds) {
            System.out.println(p.getFileName());
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

Surround the string with <html></html> and break the lines with <br/>.

JLabel l = new JLabel("<html>Hello World!<br/>blahblahblah</html>", SwingConstants.CENTER);

In short:

1. static_cast<>() gives you a compile time checking ability, C-Style cast doesn't.
2. static_cast<>() is more readable and can be spotted easily anywhere inside a C++ source code, C_Style cast is'nt.
3. Intentions are conveyed much better using C++ casts.

More Explanation:

The static cast performs conversions between compatible types. It is similar to the C-style cast, but is more restrictive. For example, the C-style cast would allow an integer pointer to point to a char.

char c = 10;       // 1 byte
int *p = (int*)&c; // 4 bytes

Since this results in a 4-byte pointer ( a pointer to 4-byte datatype) pointing to 1 byte of allocated memory, writing to this pointer will either cause a run-time error or will overwrite some adjacent memory.

*p = 5; // run-time error: stack corruption

In contrast to the C-style cast, the static cast will allow the compiler to check that the pointer and pointee data types are compatible, which allows the programmer to catch this incorrect pointer assignment during compilation.

int *q = static_cast<int*>(&c); // compile-time error

Also, note that you can add to a namespace. This is clearer with an example, what I mean is that you can have:

namespace MyNamespace
{
    double square(double x) { return x * x; }
}

in a file square.h, and

namespace MyNamespace
{
    double cube(double x) { return x * x * x; }
}

in a file cube.h. This defines a single namespace MyNamespace (that is, you can define a single namespace across multiple files).

@Bean(name = "restTemplateByPassSSL")
public RestTemplate restTemplateByPassSSL()
        throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
    TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
    HostnameVerifier hostnameVerifier = (s, sslSession) -> true;
    SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
    CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);

    return new RestTemplate(requestFactory);
}

Try this code :

return context.EntitytableName.AsEnumerable().Find(p => p.LoginID.Equals(loginID) && p.Password.Equals(password)).Select(p => new ModelTableName{ FirstName = p.FirstName, UserID = p.UserID });

In this case I believe that the following is equivalent:

l = sum([1,2,3,4]) % 2

The only problem with this is that it creates big numbers, but maybe that is better than repeated modulo operations?

I believe you are trying to compare two strings representing values, the function you are looking for is:

int atoi(const char *nptr);

or

long int strtol(const char *nptr, char **endptr, int base);

these functions will allow you to convert a string to an int/long int:

int val = strtol("555", NULL, 10);

and compare it to another value.

int main (int argc, char *argv[])
{
    long int val = 0;
    if (argc < 2)
    {
        fprintf(stderr, "Usage: %s number\n", argv[0]);
        exit(EXIT_FAILURE);
    }

    val = strtol(argv[1], NULL, 10);
    printf("%d is %s than 555\n", val, val > 555 ? "bigger" : "smaller");

    return 0;
}

Dirk's method above will absolutely work, but if you're looking for a way to bring in a long string where whitespace/structure is important to preserve (example: a SQL query using RODBC) there is a two step solution.

1) Bring the text string in across multiple lines

long_string <- "this
is 
a 
long
string
with
whitespace"

2) R will introduce a bunch of \n characters. Strip those out with strwrap(), which destroys whitespace, per the documentation:

strwrap(long_string, width=10000, simplify=TRUE)

By telling strwrap to wrap your text to a very, very long row, you get a single character vector with no whitespace/newline characters.

Detection is automatic. You must specify what css can be used for each screen resolution:

/* for all screens, use 14px font size */
body {  
    font-size: 14px;    
}
/* responsive, form small screens, use 13px font size */
@media (max-width: 479px) {
    body {
        font-size: 13px;
    }
}

If you are looking for the last row of a column, use:

Sub SelectFirstColumn()
   SelectEntireColumn (1)
End Sub

Sub SelectSecondColumn()
    SelectEntireColumn (2)
End Sub

Sub SelectEntireColumn(columnNumber)
    Dim LastRow
    Sheets("sheet1").Select
    LastRow = ActiveSheet.Columns(columnNumber).SpecialCells(xlLastCell).Row

    ActiveSheet.Range(Cells(1, columnNumber), Cells(LastRow, columnNumber)).Select
End Sub

Other commands you will need to get familiar with are copy and paste commands:

Sub CopyOneToTwo()
    SelectEntireColumn (1)
    Selection.Copy

    Sheets("sheet1").Select
    ActiveSheet.Range("B1").PasteSpecial Paste:=xlPasteValues
End Sub

Finally, you can reference worksheets in other workbooks by using the following syntax:

Dim book2
Set book2 = Workbooks.Open("C:\book2.xls")
book2.Worksheets("sheet1")

I have written a class in C# to handle common functions for working with the binomial coefficient, which is the type of problem that your problem falls under. It performs the following tasks:

1. Outputs all the K-indexes in a nice format for any N choose K to a file. The K-indexes can be substituted with more descriptive strings or letters. This method makes solving this type of problem quite trivial.

2. Converts the K-indexes to the proper index of an entry in the sorted binomial coefficient table. This technique is much faster than older published techniques that rely on iteration. It does this by using a mathematical property inherent in Pascal's Triangle. My paper talks about this. I believe I am the first to discover and publish this technique.

3. Converts the index in a sorted binomial coefficient table to the corresponding K-indexes. I believe it is also faster than the other solutions.

4. Uses Mark Dominus method to calculate the binomial coefficient, which is much less likely to overflow and works with larger numbers.

5. The class is written in .NET C# and provides a way to manage the objects related to the problem (if any) by using a generic list. The constructor of this class takes a bool value called InitTable that when true will create a generic list to hold the objects to be managed. If this value is false, then it will not create the table. The table does not need to be created in order to perform the 4 above methods. Accessor methods are provided to access the table.

6. There is an associated test class which shows how to use the class and its methods. It has been extensively tested with 2 cases and there are no known bugs.

To read about this class and download the code, see Tablizing The Binomial Coeffieicent.

It should be pretty straight forward to port the class over to C++.

The solution to your problem involves generating the K-indexes for each N choose K case. For example:

int NumPeople = 10;
int N = TotalColumns;
// Loop thru all the possible groups of combinations.
for (int K = N - 1; K < N; K++)
{
   // Create the bin coeff object required to get all
   // the combos for this N choose K combination.
   BinCoeff<int> BC = new BinCoeff<int>(N, K, false);
   int NumCombos = BinCoeff<int>.GetBinCoeff(N, K);
   int[] KIndexes = new int[K];
   BC.OutputKIndexes(FileName, DispChars, "", " ", 60, false);
   // Loop thru all the combinations for this N choose K case.
   for (int Combo = 0; Combo < NumCombos; Combo++)
   {
      // Get the k-indexes for this combination, which in this case
      // are the indexes to each person in the problem set.
      BC.GetKIndexes(Loop, KIndexes);
      // Do whatever processing that needs to be done with the indicies in KIndexes.
      ...
   }
}

The OutputKIndexes method can also be used to output the K-indexes to a file, but it will use a different file for each N choose K case.

I believe best practice these days is H/5 * * * *, which means every 5 minutes with a hashing factor to avoid all jobs starting at EXACTLY the same time.

What I started doing a while back was to have a single sub that sets the size of all my controls. I can then run this sub from any point in the code where the controls grow or shrink. It's sometimes a lot of extra finicky work, but it keeps my buttons from eating my spreadsheet.

I recommend the answers with sed and awk for just getting the line number, rather than using grep to get the entire matching line and then removing that from the output with cut or another tool. For completeness, you can also use Perl:

perl -nE '/pattern/ && say $.' filename

or Ruby:

ruby -ne 'puts $. if /pattern/' filename

You can't.

The only way to get a list of all event listeners attached to a node is to intercept the listener attachment call.

DOM4 addEventListener

Says

Append an event listener to the associated list of event listeners with type set to type, listener set to listener, and capture set to capture, unless there already is an event listener in that list with the same type, listener, and capture.

Meaning that an event listener is added to the "list of event listeners". That's all. There is no notion of what this list should be nor how you should access it.

A clustered index is like the contents of a phone book. You can open the book at 'Hilditch, David' and find all the information for all of the 'Hilditch's right next to each other. Here the keys for the clustered index are (lastname, firstname).

This makes clustered indexes great for retrieving lots of data based on range based queries since all the data is located next to each other.

Since the clustered index is actually related to how the data is stored, there is only one of them possible per table (although you can cheat to simulate multiple clustered indexes).

A non-clustered index is different in that you can have many of them and they then point at the data in the clustered index. You could have e.g. a non-clustered index at the back of a phone book which is keyed on (town, address)

Imagine if you had to search through the phone book for all the people who live in 'London' - with only the clustered index you would have to search every single item in the phone book since the key on the clustered index is on (lastname, firstname) and as a result the people living in London are scattered randomly throughout the index.

If you have a non-clustered index on (town) then these queries can be performed much more quickly.

Hope that helps!

A couple of gotchas that are colloraries to Andrew Shelansky's excellent answer and to disagree a little with doesn't really change the way that the compiler reads the code

Because your function prototypes are compiled as C, you can't have overloading of the same function names with different parameters - that's one of the key features of the name mangling of the compiler. It is described as a linkage issue but that is not quite true - you will get errors from both the compiler and the linker.

The compiler errors will be if you try to use C++ features of prototype declaration such as overloading.

The linker errors will occur later because your function will appear to not be found, if you do not have the extern "C" wrapper around declarations and the header is included in a mixture of C and C++ source.

One reason to discourage people from using the compile C as C++ setting is because this means their source code is no longer portable. That setting is a project setting and so if a .c file is dropped into another project, it will not be compiled as c++. I would rather people take the time to rename file suffixes to .cpp.

This one is great:

<style type="text/css">
textarea.test
{  
width: 100%;
height: 100%;
border-color: Transparent;     
}
</style>
<textarea class="test"></textarea>

Thread.sleep() takes in the number of milliseconds to sleep, not seconds.

Sleeping for one millisecond is not noticeable. Try Thread.sleep(1000) to sleep for one second.

For my Samsung S3, I had to go into Developer Options on the phone, untick the "USB debugging" checkbox, then re-tick it.

Then the dialog will appear, asking if you want to allow USB Debugging.

Once I'd done this, the "adb devices" command no longer showed "unauthorized" as my device name.

(Several months later..)

Actually, the same was true for connecting my Galaxy Tab S device, and the menu options were in slightly different places with Android 4.4.2:

I was looking for a solution for Windows but didn't found any. Finally, figured out that that there is a dangling java application using the port. Maybe it's the earlier instance of the spring application and ended the process.

I used tcpview from Microsoft. It shows services/applications using which port on your computer.

You can end the process. And Done!

import numpy as np

mean_data = np.array([
[6.0, 315.0, 4.8123788544375692e-06],
[6.5, 0.0, 2.259217450023793e-06],
[6.5, 45.0, 9.2823565008402673e-06],
[6.5, 90.0, 8.309270169336028e-06],
[6.5, 135.0, 6.4709418114245381e-05],

[6.5, 315.0, 2.2727114437176048e-05]])

R = mean_data[:,0]
print R
print R.shape

EDIT

The reason why you had an invalid index error is the lack of a comma between mean_data and the values you wanted to add.

Also, np.append returns a copy of the array, and does not change the original array. From the documentation :

Returns : append : ndarray

A copy of arr with values appended to axis. Note that append does not occur in-place: a new array is allocated and filled. If axis is None, out is a flattened array.

So you have to assign the np.append result to an array (could be mean_data itself, I think), and, since you don't want a flattened array, you must also specify the axis on which you want to append.

With that in mind, I think you could try something like

mean_data = np.append(mean_data, [[ur, ua, np.mean(data[samepoints,-1])]], axis=0)

Do have a look at the doubled [[ and ]] : I think they are necessary since both arrays must have the same shape.

Another alternative is the following, although not the cleanest as it assumes the image to be the only element in a container, such as in this case:

<header class="siteHeader">
  <img src="img" class="siteLogo" />
</header>

You can then use the container as a mask with the desired size, and surround the image with a negative margin to move it into the right position:

.siteHeader{
    width: 50px;
    height: 50px;
    overflow: hidden;
}

.siteHeader .siteLogo{
    margin: -100px;
}

Demo can be seen in this JSFiddle.

Only seems to work in IE>9, and probably all significant versions of all other browsers.

You may use Request.Cookies collection to read the cookies.

if(Request.Cookies["key"]!=null)

Putting the model dot property in strings worked for me: ModelState.AddModelError("Item1.Month", "This is not a valid date");

It sounds to me like you want to be able to easily pass a string created using printf-style formatting to the function you already have that takes a simple string. You can create a wrapper function using stdarg.h facilities and vsnprintf() (which may not be readily available, depending on your compiler/platform):

#include <stdarg.h>
#include <stdio.h>

// a function that accepts a string:

void foo( char* s);

// You'd like to call a function that takes a format string 
//  and then calls foo():

void foofmt( char* fmt, ...)
{
    char buf[100];     // this should really be sized appropriately
                       // possibly in response to a call to vsnprintf()
    va_list vl;
    va_start(vl, fmt);

    vsnprintf( buf, sizeof( buf), fmt, vl);

    va_end( vl);

    foo( buf);
}



int main()
{
    int val = 42;

    foofmt( "Some value: %d\n", val);
    return 0;
}

For platforms that don't provide a good implementation (or any implementation) of the snprintf() family of routines, I've successfully used a nearly public domain snprintf() from Holger Weiss.
