I'll answer your question with a counter-question...

What do you think of Org-mode? It's not as pure as Markdown, but it is Markdown-like, and I find it as easy to work with, and it allows embedding of Latex. Cf. http://www.gnu.org/software/emacs/manual/html_node/org/Embedded-LaTeX.html

Postscript

In case you haven't looked at org-mode, it has one great strength as a general purpose "natural markup language" over Markdown, namely its treatment of tables. The source:

| 1 | 0 | 0 |
| -1 | 1 | 0 |
| -1 | -1 | 1 |

represents just what you think it will...

And the Latex is rendered in pieces using tex-mode's preview-latex.

In case the XML store in the CLOB field in the database table. E.g for this XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Awmds>
    <General_segment>
        <General_segment_id>
        <Customs_office_code>000</Customs_office_code>
    </General_segment_id>
</General_segment>
</Awmds>

This is the Extract Query:

SELECT EXTRACTVALUE (
    xmltype (T.CLOB_COLUMN_NAME),
    '/Awmds/General_segment/General_segment_id/Customs_office_code')
    AS Customs_office_code
FROM TABLE_NAME t;

It seems to me, this is a cross-domain issue since you're not allowed to make a request to a different domain.

You have to find solutions to this problem: - Use a proxy script, running on your server that will forward your request and will handle the response sending it to the browser Or - The service you're making the request should have JSONP support. This is a cross-domain technique. You might want to read this http://en.wikipedia.org/wiki/JSONP

If you are using bootstrap 3, use tag, like this <small><span class="glyphicon glyphicon-send"></span></small> It works perfect for Bootstrap 3.
You can even use multiple <small> tags to set the size more smaller.
Code:
<small><small><span class="glyphicon glyphicon-send"></span></small></small>

You can also have different urls for apps in one server configuration:

• yourdomain.com/app1/* -> to Node.js process running locally http://127.0.0.1:3000
• yourdomain.com/app2/* -> to Node.js process running locally http://127.0.0.1:4000

In /etc/nginx/sites-enabled/yourdomain:

server {
    listen 80;
    listen [::]:80;
    server_name yourdomain.com;

    location ^~ /app1/{
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass    http://127.0.0.1:3000/;
    }

    location ^~ /app2/{
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass    http://127.0.0.1:4000/;
    }
}

Restart nginx:

sudo service nginx restart

Starting applications.

node app1.js

var http = require('http');
http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello from app1!\n');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');

node app2.js

var http = require('http');
http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello from app2!\n');
}).listen(4000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:4000/');

if you have a nice selector (for example all .txt files in a dir) you could do:

for i in *.txt; do chmod 755 "$i"; done

bash for loop

or a variant of yours:

while read line; do chmod 755 "$line"; done < file.txt

Your syntax is incorrect, you should pass the value as the second parameter:

jQuery(this).prev("li").attr("id","newId");

Paste this next to your values(bytes) and this will automatically change it to whatever your size of value is.

=IF(G10>=1099511627776,CONCATENATE(ROUND((G10/1024/1024/1024/1024),1)," TB"),IF(G10>=1073741824,CONCATENATE(ROUND((G10/1024/1024/1024),1)," GB"),IF(G10>=1048576,CONCATENATE(ROUND((G10/1024/1024),1)," MB"),IF(G10>=1024,CONCATENATE(ROUND((G10/1024),1)," KB"),IF(G10>=1,CONCATENATE((G10)," BYTES"),0)))))

Let us assume you got the start date and end date from the UI and stored it in the scope variable in the controller.

Then declare an array which will get reset on every function call so that on the next call for the function the new data can be stored.

var dayLabel = [];

Remember to use new Date(your starting variable) because if you dont use the new date and directly assign it to variable the setDate function will change the origional variable value in each iteration`

for (var d = new Date($scope.startDate); d <= $scope.endDate; d.setDate(d.getDate() + 1)) {
                dayLabel.push(new Date(d));
            }

You can use debugger; within your code. If the developer console is open, execution will break. It works in firebug as well.

Get value from an EditText control in android. EditText getText property use to get value an EditText:

The error code indicates the function definition cannot be found. Make sure you're calling the function from the same workspace as the divrat.m file is stored. And make sure divrat function is not a subfunction, it should be first function declaration in the file. You can also try to call the function from the same divrat.m file in order to see if the problem is with workspace selection or the function.

By the way, why didn't you simply say

s = sqrt(diag(C));

Wouldn't it be the same?

You can use CTE:

WITH DistinctMonitoringJob AS (
    SELECT DISTINCT Category Distinct_Category FROM MonitoringJob 
)

SELECT Distinct_Category 
FROM DistinctMonitoringJob 
ORDER BY Distinct_Category DESC

Quickfix

I had similar issue and I resolved it doing the following

1. Navigate to jenkins > Manage jenkins > In-process Script Approval
2. There was a pending command, which I had to approve.

Alternative 1: Disable sandbox

As this article explains in depth, groovy scripts are run in sandbox mode by default. This means that a subset of groovy methods are allowed to run without administrator approval. It's also possible to run scripts not in sandbox mode, which implies that the whole script needs to be approved by an administrator at once. This preventing users from approving each line at the time.

Running scripts without sandbox can be done by unchecking this checkbox in your project config just below your script:

Alternative 2: Disable script security

As this article explains it also possible to disable script security completely. First install the permissive script security plugin and after that change your jenkins.xml file add this argument:

-Dpermissive-script-security.enabled=true

So you jenkins.xml will look something like this:

<executable>..bin\java</executable>
<arguments>-Dpermissive-script-security.enabled=true -Xrs -Xmx4096m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=80 --webroot="%BASE%\war"</arguments>

Make sure you know what you are doing if you implement this!

You may need to handle javax.persistence.RollbackException

Here's a query to update a table based on a comparison of another table. If record is not found in tableB, it will update the "active" value to "n". If it's found, will set the value to NULL

UPDATE tableA
LEFT JOIN tableB ON tableA.id = tableB.id
SET active = IF(tableB.id IS NULL, 'n', NULL)";

Hope this helps someone else.

This query should be written before the query which create or update data in the database, this query looks like :

mysql_query("set names 'utf8'");

Note that you should write the encode which you are using in the header for example if you are using utf-8 you add it like this in the header or it will couse a problem with Internet Explorer

so your page looks like this

<html>
    <head>
        <title>page title</title>
        <meta charset="UTF-8" />   
    </head>
    <body>
    <?php
            mysql_query("set names 'utf8'");   
            $sql = "INSERT * FROM ..... ";  
            mysql_query($sql);
    ?>    

    </body>
</html>

The easiest process to symbolicate crash logs:

1. preserve the xcarchive file from the organizer during IPA building process for future use.
2. When the crash occurs, collect the crash logs from affected device. The extension should be .crash. If the crash log is in .ips format, just rename it to .crash.
3. Double click the xcarchive from the stored path to make it appear in organizer(if not present already).
4. open in xcode window->devices and simulators -> view device logs -> all logs -> drag and drop the .crash file.

Wait for 5secs. Bang! the application calls in stack trace will be symbolicated! You may still see a lot of symbols though! those are internal library and framework calls.

This is the easiest one, tried and tested!

I had the same issue I remove the following script and it worked for me.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>

I had the same issue and eventually chose to use a Rectangle element:

<Rectangle HorizontalAlignment="Stretch" Fill="Blue" Height="4"/>

In my opinion it's somewhat easier to modify/shape than a separator. Of course the Separator is a very easy and neat solution for simple separations :)

You need to name the entity that holds the association to User. For example,

... INNER JOIN ug.user u ...

That's the "path" the error message is complaining about -- path from UserGroup to User entity.

Hibernate relies on declarative JOINs, for which the join condition is declared in the mapping metadata. This is why it is impossible to construct the native SQL query without having the path.

What about this? I never found this patter around but I was just trying to exclude one or more properties without the need of creating an extra object. This seems to do the job but there are some side effects I'm not able to see. For sure is not very readable.

const postData = {
   token: 'secret-token',
   publicKey: 'public is safe',
   somethingElse: true,
};

const a = {
   ...(({token, ...rest} = postData) => (rest))(),
}

/**
a: {
   publicKey: 'public is safe',
   somethingElse: true,
}
*/

Try changing it to.

 Response.Clear();
 Response.ClearHeaders();
 Response.ClearContent();
 Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
 Response.AddHeader("Content-Length", file.Length.ToString());
 Response.ContentType = "text/plain";
 Response.Flush();
 Response.TransmitFile(file.FullName);
 Response.End();

Those two parameters (or variants of) are sent, by convention, with all events.

• sender: The object which has raised the event
• e an instance of EventArgs including, in many cases, an object which inherits from EventArgs. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.

In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs are Empty as there is no further information about the event.

Looking at the 2 parameters separately, here are some examples where they are useful.

sender

Say you have multiple buttons on a form. These buttons could contain a Tag describing what clicking them should do. You could handle all the Click events with the same handler, and depending on the sender do something different

private void HandleButtonClick(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.Tag == "Hello")
      MessageBox.Show("Hello")
    else if(btn.Tag == "Goodbye")
       Application.Exit();
    // etc.
}

Disclaimer : That's a contrived example; don't do that!

e

Some events are cancelable. They send CancelEventArgs instead of EventArgs. This object adds a simple boolean property Cancel on the event args. Code handling this event can cancel the event:

private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
    if(/* some condition*/)
    {
       // Cancel this event
       e.Cancel = true;
    }
}

This has been possible since Java 7. The syntax for a multi-catch block is:

try { 
  ...
} catch (IllegalArgumentException | SecurityException | IllegalAccessException |
            NoSuchFieldException e) { 
  someCode();
}

Remember, though, that if all the exceptions belong to the same class hierarchy, you can simply catch that base exception type.

Also note that you cannot catch both ExceptionA and ExceptionB in the same block if ExceptionB is inherited, either directly or indirectly, from ExceptionA. The compiler will complain:

Alternatives in a multi-catch statement cannot be related by subclassing
  Alternative ExceptionB is a subclass of alternative ExceptionA

The fix for this is to only include the ancestor exception in the exception list, as it will also catch exceptions of the descendant type.

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

Why not do it XAML?

<ComboBox x:Name="myComboBoxMenu" PlaceholderText="Hello"/>

If you just want to detect mobile devices in generel, Cake has build in support using RequestHandler->isMobile() (http://book.cakephp.org/2.0/en/core-libraries/components/request-handling.html#RequestHandlerComponent::isMobile)

You can use the following method

 private function generateStringCondition($value = '',$field = '', $operator = '', $regex = '', $wildcardStart = '', $wildcardEnd = ''){
        if($value != ''){
            $where = " $field $regex '$wildcardStart".strtolower($value)."$wildcardEnd' ";

            $searchArray = explode(' ', $value);

            if(sizeof($searchArray) > 1){

                foreach ($searchArray as $key=>$value){
                    $where .="$operator $field $regex '$wildcardStart".strtolower($value)."$wildcardEnd'";
                }

            }

        }else{
            $where = '';
        }
        return $where;
    }

use this method like below

   $where =  $this->generateStringCondition($yourSearchString,  'LOWER(columnName)','or', 'like',  '%', '%');
  $sql = "select * from table $where";

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

You can use functors if you want a less generic and more precise control under the hood. Example with my win32 api to forward api message from a class to another class.

IListener.h

#include <windows.h>
class IListener { 
    public:
    virtual ~IListener() {}
    virtual LRESULT operator()(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam) = 0;
};

Listener.h

#include "IListener.h"
template <typename D> class Listener : public IListener {
    public:
    typedef LRESULT (D::*WMFuncPtr)(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam); 

    private:
    D* _instance;
    WMFuncPtr _wmFuncPtr; 

    public:
    virtual ~Listener() {}
    virtual LRESULT operator()(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam) override {
        return (_instance->*_wmFuncPtr)(hWnd, uMsg, wParam, lParam);
    }

    Listener(D* instance, WMFuncPtr wmFuncPtr) {
        _instance = instance;
        _wmFuncPtr = wmFuncPtr;
    }
};

Dispatcher.h

#include <map>
#include "Listener.h"

class Dispatcher {
    private:
        //Storage map for message/pointers
        std::map<UINT /*WM_MESSAGE*/, IListener*> _listeners; 

    public:
        virtual ~Dispatcher() { //clear the map }

        //Return a previously registered callable funtion pointer for uMsg.
        IListener* get(UINT uMsg) {
            typename std::map<UINT, IListener*>::iterator itEvt;
            if((itEvt = _listeners.find(uMsg)) == _listeners.end()) {
                return NULL;
            }
            return itEvt->second;
        }

        //Set a member function to receive message. 
        //Example Button->add<MyClass>(WM_COMMAND, this, &MyClass::myfunc);
        template <typename D> void add(UINT uMsg, D* instance, typename Listener<D>::WMFuncPtr wmFuncPtr) {
            _listeners[uMsg] = new Listener<D>(instance, wmFuncPtr);
        }

};

Usage principles

class Button {
    public:
    Dispatcher _dispatcher;
    //button window forward all received message to a listener
    LRESULT onMessage(HWND hWnd, UINT uMsg, WPARAM w, LPARAM l) {
        //to return a precise message like WM_CREATE, you have just
        //search it in the map.
        return _dispatcher[uMsg](hWnd, uMsg, w, l);
    }
};

class Myclass {
    Button _button;
    //the listener for Button messages
    LRESULT button_listener(HWND hWnd, UINT uMsg, WPARAM w, LPARAM l) {
        return 0;
    }

    //Register the listener for Button messages
    void initialize() {
        //now all message received from button are forwarded to button_listener function 
       _button._dispatcher.add(WM_CREATE, this, &Myclass::button_listener);
    }
};

Good luck and thank to all for sharing knowledge.

Something like this works for me, you can then call the function, and it will dispatch itself onto a new thread.

from thread import start_new_thread

def dowork(asynchronous=True):
    if asynchronous:
        args = (False)
        start_new_thread(dowork,args) #Call itself on a new thread.
    else:
        while True:
            #do something...
            time.sleep(60) #sleep for a minute
    return

Use this regular expression to match square brackets or single quotes:

/[\[\]']+/g

Replace with the empty string.

console.log("['abc','xyz']".replace(/[\[\]']+/g,''));

Perl doesn't have a console but the debugger can be used as one. At a command prompt, type perl -de 1. (The value "1" doesn't matter, it's just a valid statement that does nothing.)

There are also a couple of options for a Perl shell.

If you want to add meta data tags for page description, use the SETTINGS of your DNN page to add Description and Keywords. Beyond that, the best way to go when modifying the HEAD is to dynamically inject your code into the HEAD via a third party module.

Found at http://www.dotnetnuke.com/Resources/Forums/forumid/7/threadid/298385/scope/posts.aspx

This may allow other meta tags, if you're lucky

Additional HEAD tags can be placed into Page Settings > Advanced Settings > Page Header Tags.

• C++ doesn't employ any memory manager by its own. Other languages like C#, Java has garbage collector to handle the memory
• C++ implementations typically use operating system routines to allocate the memory and too much new/delete could fragment the available memory
• With any application, if the memory is frequently being used it's advisable to pre-allocate it and release when not required.
• Improper memory management could lead memory leaks and it's really hard to track. So using stack objects within the scope of function is a proven technique
• The downside of using stack objects are, it creates multiple copies of objects on returning, passing to functions etc. However smart compilers are well aware of these situations and they've been optimized well for performance
• It's really tedious in C++ if the memory being allocated and released in two different places. The responsibility for release is always a question and mostly we rely on some commonly accessible pointers, stack objects (maximum possible) and techniques like auto_ptr (RAII objects)
• The best thing is that, you've control over the memory and the worst thing is that you will not have any control over the memory if we employ an improper memory management for the application. The crashes caused due to memory corruptions are the nastiest and hard to trace.

If you are using SVG with JavaScript you need to enable this because it's disabled by default. Use

<script data-search-pseudo-elements ... >

inside your script tag.

Just add parameters, split by comma:

UPDATE tablename SET column1 = "value1", column2 = "value2" ....

see the link also MySQL UPDATE

Here is a plunker showing how you can use it with the ngClass directive.

I'm demonstrating with divs instead of imgs though.

Template:

<ul>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 1}" (click)="setSelected(1)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 2}" (click)="setSelected(2)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 3}" (click)="setSelected(3)"> </div></li>
</ul>

TS:

export class App {
  selectedIndex = -1;

  setSelected(id: number) {
    this.selectedIndex = id;
  }
}

You may be looking for the Git feature called submodules. This feature helps you manage dependent repositories that are nested inside your main repository.

Solution1

You can set the key path in the storyboard

Set the text to your multiline title e.g. hello ? + ? multiline

You need to press ? + ? to move text to next line.

Then add the key path

titleLabel.textAlignment as Number and value 1, 1 means NSTextAlignmentCenter
titleLabel.numberOfLines as Number and value 0, 0 means any number of lines

This will not be reflected on IB/Xcode, but will be in centre at run time (device/simulator)

If you want to see the changes on Xcode you need to do the following: (remember you can skip these steps)

1. Subclass the UIButton to make the button designable:

   import UIKit
   @IBDesignable class UIDesignableButton: UIButton {}
   

2. Assign this designable subclass to the buttons you're modifying:

3. Iff done right, you will see the visual update in IB when the Designables state is "Up to date" (which can take several seconds):

Solution2

If you want to write the code, then do the long process

1.Create IBOutlet for button
2.Write code in viewDidLoad

btn.titleLabel.textAlignment = .Center
btn.titleLabel.numberOfLines = 0

Solution3

In newer version of xcode (mine is xcode 6.1) we have property attributed title
Select Attributed then select the text and press centre option below

P.S. The text was not coming multiline for that I have to set the

btn.titleLabel.numberOfLines = 0

<div class="container-fluid">
   <div class="col-sm-12 text-center">
       <button class="btn btn-primary" title="Submit"></button>
       <button class="btn btn-warning" title="Cancel"></button>
   </div>
</div>

Currently VARCHAR behaves exactly the same as VARCHAR2. However, the type VARCHAR should not be used as it is reserved for future usage.

Taken from: Difference Between CHAR, VARCHAR, VARCHAR2

Another place this error can happen in is assigning a value that has a comma outside of a string. For example:

SET totalvalue = (IFNULL(i.subtotal,0) + IFNULL(i.tax,0),0)

use recursion:

def fib(n):
    if n == 0:
        return 0
    elif n == 1:
        return 1
    else:
        return fib(n-1) + fib(n-2)
x=input('which fibonnaci do you want?')
print fib(x)

class SuperClass
{
    public void method1()
    {
        System.out.println("superclass method1");
        SuperClass se=new SuperClass();
        se.method2();
    }

    public void method2()
    {
        System.out.println("superclass method2");
    }
}


class SubClass extends SuperClass
{
    @Override

    }

    @Override
    public void method2()
    {
        System.out.println("subclass method2");
    }
}

calling

SubClass mSubClass = new SubClass();
mSubClass.method1();

outputs

superclass method1
superclass method2

The .c is the source file and .h is the header file.

$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, OAUTH_TOKEN, OAUTH_TOKEN_SECRET);

Your disabled attribute requires a boolean value:

<input :disabled="validated" />

Notice how i've only checked if validated - This should work as 0 is falsey ...e.g

0 is considered to be false in JS (like undefined or null)

1 is in fact considered to be true

To be extra careful try: <input :disabled="!!validated" />

This double negation turns the falsey or truthy value of 0 or 1 to false or true

don't believe me? go into your console and type !!0 or !!1 :-)

Also, to make sure your number 1 or 0 are definitely coming through as a Number and not the String '1' or '0' pre-pend the value you are checking with a + e.g <input :disabled="!!+validated"/> this turns a string of a number into a Number e.g

+1 = 1 +'1' = 1 Like David Morrow said above you could put your conditional logic into a method - this gives you more readable code - just return out of the method the condition you wish to check.

Assuming a is a string. The Slice notation in python has the syntax -

list[<start>:<stop>:<step>]

So, when you do a[::-1], it starts from the end towards the first taking each element. So it reverses a. This is applicable for lists/tuples as well.

Example -

>>> a = '1234'
>>> a[::-1]
'4321'

Then you convert it to int and then back to string (Though not sure why you do that) , that just gives you back the string.

It is SUBSTITUTE(B1," ",""), not REPLACE(xx;xx;xx).

I use Postman.

Execute whatever call you want to do. Then, postman provides a handy tool to show the curl code .

Run it in the terminal.

You can use the following steps, its worked for me to drop table with constraint,solution already explained in the above comment, i just added screen shot for that -

If you can invert your logic you can use the Array.Clear() method to set the boolean array to false.

        int upperLimit = 21;
        double optimizeMe = Math.Sqrt(upperLimit);

        bool[] seiveContainer = new bool[upperLimit];
        Array.Clear(seiveContainer, 0, upperLimit);

Omitting the html, head, and body tags is certainly allowed by the HTML specs. The underlying reason is that browsers have always sought to be consistent with existing web pages, and the very early versions of HTML didn't define those elements. When HTML 2.0 first did, it was done in a way that the tags would be inferred when missing.

I often find it convenient to omit the tags when prototyping and especially when writing test cases as it helps keep the mark-up focused on the test in question. The inference process should create the elements in exactly the manner that you see in Firebug, and browsers are pretty consistent in doing that.

But...

IE has at least one known bug in this area. Even IE9 exhibits this. Suppose the markup is this:

<!DOCTYPE html>
<title>Test case</title>
<form action='#'>
   <input name="var1">
</form>

You should (and do in other browsers) get a DOM that looks like this:

HTML
    HEAD
        TITLE
    BODY
        FORM action="#"
            INPUT name="var1"

But in IE you get this:

HTML
    HEAD
       TITLE
       FORM action="#"
           BODY
               INPUT name="var1"
    BODY

See it for yourself.

This bug seems limited to the form start tag preceding any text content and any body start tag.

If you want to apply it as a commit, use git am.

asynchronous call ping command to block current code to execution in specified milliseconds.

• ping command is Cross-platform
• start /b means: start program but not show window.

code as below:

const { execSync } = require('child_process')
// delay(blocking) specified milliseconds
function sleep(ms) {
    // special Reserved IPv4 Address(RFC 5736): 192.0.0.0
    // refer: https://en.wikipedia.org/wiki/Reserved_IP_addresses
    execSync(`start /b ping 192.0.0.0 -n 1 -w ${ms} > nul`)
}

// usage
console.log("delay 2500ms start\t:" + (new Date().getTime() / 1000).toFixed(3))
sleep(2500)
console.log("delay 2500ms end\t:" + (new Date().getTime() / 1000).toFixed(3))

notice important: Above is not a precision solution, it just approach the blocking time

byte test[] = new byte[3];
test[0] = 0x0A;
test[1] = 0xFF;
test[2] = 0x01;

for (byte theByte : test)
{
  System.out.println(Integer.toHexString(theByte));
}

NOTE: test[1] = 0xFF; this wont compile, you cant put 255 (FF) into a byte, java will want to use an int.

you might be able to do...

test[1] = (byte) 0xFF;

I'd test if I was near my IDE (if I was near my IDE I wouln't be on Stackoverflow)

use os.path.isdir(path)

more info here http://docs.python.org/library/os.path.html

This worked for me.

header = ['row1', 'row2', 'row3']
some_list = [1, 2, 3]
with open('test.csv', 'wt', newline ='') as file:
    writer = csv.writer(file, delimiter=',')
    writer.writerow(i for i in header)
    for j in some_list:
        writer.writerow(j)

Array.prototype.indexOf.call(this.parentElement.children, this);

Or use let statement.

Swift 4

extension UIView {

func fadeIn(duration: TimeInterval = 0.5, delay: TimeInterval = 0.0, completion: @escaping ((Bool) -> Void) = {(finished: Bool) -> Void in }) {
    self.alpha = 0.0

    UIView.animate(withDuration: duration, delay: delay, options: UIViewAnimationOptions.curveEaseIn, animations: {
        self.isHidden = false
        self.alpha = 1.0
    }, completion: completion)
}

func fadeOut(duration: TimeInterval = 0.5, delay: TimeInterval = 0.0, completion: @escaping (Bool) -> Void = {(finished: Bool) -> Void in }) {
    self.alpha = 1.0

    UIView.animate(withDuration: duration, delay: delay, options: UIViewAnimationOptions.curveEaseIn, animations: {

    }) { (completed) in
        self.isHidden = true
        completion(true)
    }
}
}

And to use use it, simple call these functions like:

yourView.fadeOut() // this will hide your view with animation
yourView.fadeIn() /// this will show your view with animation

Description

You can use another overload of the DropDownList method. Pick the one you need and pass in a object with your html attributes.

Sample

@Html.DropDownList("CategoryID", null, new { @onchange="location = this.value;" })

More Information

• MSDN - SelectExtensions.DropDownList Method

1) To redirect to the login page / from the login page, don't use the Redirect() methods. Use FormsAuthentication.RedirectToLoginPage() and FormsAuthentication.RedirectFromLoginPage() !

2) You should just use RedirectToAction("action", "controller") in regular scenarios.. You want to redirect in side the Initialize method? Why? I don't see why would you ever want to do this, and in most cases you should review your approach imo.. If you want to do this for authentication this is DEFINITELY the wrong way (with very little chances foe an exception) Use the [Authorize] attribute on your controller or method instead :)

UPD: if you have some security checks in the Initialise method, and the user doesn't have access to this method, you can do a couple of things: a)

Response.StatusCode = 403;
Response.End();

This will send the user back to the login page. If you want to send him to a custom location, you can do something like this (cautios: pseudocode)

Response.Redirect(Url.Action("action", "controller"));

No need to specify the full url. This should be enough. If you completely insist on the full url:

Response.Redirect(new Uri(Request.Url, Url.Action("action", "controller")).ToString());

Just do;

System.IO.FileInfo fi = null;
try {
  fi = new System.IO.FileInfo(fileName);
}
catch (ArgumentException) { }
catch (System.IO.PathTooLongException) { }
catch (NotSupportedException) { }
if (ReferenceEquals(fi, null)) {
  // file name is not valid
} else {
  // file name is valid... May check for existence by calling fi.Exists.
}

For creating a FileInfo instance the file does not need to exist.

Try looking at http-rest-client

https://github.com/g00dnatur3/http-rest-client

Here is a simple example:

RestClient client = RestClient.builder().build();
String geocoderUrl = "http://maps.googleapis.com/maps/api/geocode/json"
Map<String, String> params = Maps.newHashMap();
params.put("address", "beverly hills 90210");
params.put("sensor", "false");
JsonNode node = client.get(geocoderUrl, params, JsonNode.class);

The library takes care of json serialization and binding for you.

Here is another example,

RestClient client = RestClient.builder().build();
String url = ...
Person person = ...
Header header = client.create(url, person);
if (header != null) System.out.println("Location header is:" + header.value());

And one last example,

RestClient client = RestClient.builder().build();
String url = ...
Person person = client.get(url, null, Person.class); //no queryParams

Cheers!

The difference between echo, print, print_r and var_dump is very simple.

echo

echo is actually not a function but a language construct which is used to print output. It is marginally faster than the print.

echo "Hello World";    // this will print Hello World
echo "Hello ","World"; // Multiple arguments - this will print Hello World

$var_1=55;
echo "$var_1";               // this will print 55
echo "var_1=".$var_1;        // this will print var_1=55
echo 45+$var_1;              // this will print 100

$var_2="PHP";
echo "$var_2";                   // this will print PHP

$var_3=array(99,98,97)           // Arrays are not possible with echo (loop or index  value required)
$var_4=array("P"=>"3","J"=>"4"); // Arrays are not possible with echo (loop or index  value required)

You can also use echo statement with or without parenthese

echo ("Hello World");   // this will print Hello World

print

Just like echo construct print is also a language construct and not a real function. The differences between echo and print is that print only accepts a single argument and print always returns 1. Whereas echo has no return value. So print statement can be used in expressions.

print "Hello World";    // this will print Hello World
print "Hello ","World"; // Multiple arguments - NOT POSSIBLE with print
$var_1=55;
print "$var_1";               // this will print 55
print "var_1=".$var_1;        // this will print var_1=55
print 45+$var_1;              // this will print 100

$var_2="PHP";
print "$var_2";                   // this will print PHP

$var_3=array(99,98,97)           // Arrays are not possible with print (loop or index  value required)
$var_4=array("P"=>"3","J"=>"4"); // Arrays are not possible with print (loop or index  value required)

Just like echo, print can be used with or without parentheses.

print ("Hello World");   // this will print Hello World

print_r

The print_r() function is used to print human-readable information about a variable. If the argument is an array, print_r() function prints its keys and elements (same for objects).

print_r ("Hello World");    // this will print Hello World

$var_1=55;
print_r ("$var_1");               // this will print 55
print_r ("var_1=".$var_1);        // this will print var_1=55
print_r (45+$var_1);              // this will print 100

$var_2="PHP";
print_r ("$var_2");                // this will print PHP

$var_3=array(99,98,97)             // this will print Array ( [0] => 1 [1] => 2 [2] => 3 ) 
$var_4=array("P"=>"3","J"=>"4");   // this will print  Array ( [P] => 3 [J] => 4 ) 

var_dump

var_dump function usually used for debugging and prints the information ( type and value) about a variable/array/object.

var_dump($var_1);     // this will print  int(5444) 
var_dump($var_2);     // this will print  string(5) "Hello" 
var_dump($var_3);     // this will print  array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } 
var_dump($var_4);     // this will print  array(2) { ["P"]=> string(1) "3" ["J"]=> string(1) "4" }

AFAIK, All of the methods currently to capture a screenshot of android use the /dev/graphics/fb0 framebuffer. This includes ddms. It does require root to read from this stream. ddms uses adbd to request the information, so root is not required as adb has the permissions needed to request the data from /dev/graphics/fb0.

The framebuffer contains 2+ "frames" of RGB565 images. If you are able to read the data, you would have to know the screen resolution to know how many bytes are needed to get the image. each pixel is 2 bytes, so if the screen res was 480x800, you would have to read 768,000 bytes for the image, since a 480x800 RGB565 image has 384,000 pixels.

C++03 3.10/1 says: "Every expression is either an lvalue or an rvalue." It's important to remember that lvalueness versus rvalueness is a property of expressions, not of objects.

Lvalues name objects that persist beyond a single expression. For example, obj , *ptr , ptr[index] , and ++x are all lvalues.

Rvalues are temporaries that evaporate at the end of the full-expression in which they live ("at the semicolon"). For example, 1729 , x + y , std::string("meow") , and x++ are all rvalues.

The address-of operator requires that its "operand shall be an lvalue". if we could take the address of one expression, the expression is an lvalue, otherwise it's an rvalue.

 &obj; //  valid
 &12;  //invalid

You are right, that test "and"s the two operands. But the result is discarded, the only thing that stays, and thats the important part, are the flags. They are set and thats the reason why the test instruction is used (and exist).

JE jumps not when equal (it has the meaning when the instruction before was a comparison), what it really does, it jumps when the ZF flag is set. And as it is one of the flags that is set by test, this instruction sequence (test x,x; je...) has the meaning that it is jumped when x is 0.

For questions like this (and for more details) I can just recommend a book about x86 instruction, e.g. even when it is really big, the Intel documentation is very good and precise.

This is old but as it is the first result in Google,

Please note that this also happens when your MySql service is down,

I fixed this by simply restarting MySQL Server using:

/etc/init.d/mysql restart

in SSH (Command is for a CentOS/CPanel server)

Perhaps:

[1] aname bname
<0 rows> (or 0-length row.names)

I don't think that you should be using an array to maintain tokens. Neither you need a guid as a token.

You can easily use context.SerializeTicket().

See my below code.

public class RefreshTokenProvider : IAuthenticationTokenProvider
{
    public async Task CreateAsync(AuthenticationTokenCreateContext context)
    {
        Create(context);
    }

    public async Task ReceiveAsync(AuthenticationTokenReceiveContext context)
    {
        Receive(context);
    }

    public void Create(AuthenticationTokenCreateContext context)
    {
        object inputs;
        context.OwinContext.Environment.TryGetValue("Microsoft.Owin.Form#collection", out inputs);

        var grantType = ((FormCollection)inputs)?.GetValues("grant_type");

        var grant = grantType.FirstOrDefault();

        if (grant == null || grant.Equals("refresh_token")) return;

        context.Ticket.Properties.ExpiresUtc = DateTime.UtcNow.AddDays(Constants.RefreshTokenExpiryInDays);

        context.SetToken(context.SerializeTicket());
    }

    public void Receive(AuthenticationTokenReceiveContext context)
    {
        context.DeserializeTicket(context.Token);

        if (context.Ticket == null)
        {
            context.Response.StatusCode = 400;
            context.Response.ContentType = "application/json";
            context.Response.ReasonPhrase = "invalid token";
            return;
        }

        if (context.Ticket.Properties.ExpiresUtc <= DateTime.UtcNow)
        {
            context.Response.StatusCode = 401;
            context.Response.ContentType = "application/json";
            context.Response.ReasonPhrase = "unauthorized";
            return;
        }

        context.Ticket.Properties.ExpiresUtc = DateTime.UtcNow.AddDays(Constants.RefreshTokenExpiryInDays);
        context.SetTicket(context.Ticket);
    }
}

std::unique_ptr has no copy constructor. You create an instance and then ask the std::vector to copy that instance during initialisation.

error: deleted function 'std::unique_ptr<_Tp, _Tp_Deleter>::uniqu
e_ptr(const std::unique_ptr<_Tp, _Tp_Deleter>&) [with _Tp = int, _Tp_D
eleter = std::default_delete<int>, std::unique_ptr<_Tp, _Tp_Deleter> =
 std::unique_ptr<int>]'

The class satisfies the requirements of MoveConstructible and MoveAssignable, but not the requirements of either CopyConstructible or CopyAssignable.

The following works with the new emplace calls.

std::vector< std::unique_ptr< int > > vec;
vec.emplace_back( new int( 1984 ) );

See using unique_ptr with standard library containers for further reading.

Here are the examples of Filter, map and reduce functions.

numbers = [10,11,12,22,34,43,54,34,67,87,88,98,99,87,44,66]

//Filter

oddNumbers = list(filter(lambda x: x%2 != 0, numbers))

print(oddNumbers)

//Map

multiplyOf2 = list(map(lambda x: x*2, numbers))

print(multiplyOf2)

//Reduce

The reduce function, since it is not commonly used, was removed from the built-in functions in Python 3. It is still available in the functools module, so you can do:

from functools import reduce

sumOfNumbers = reduce(lambda x,y: x+y, numbers)

print(sumOfNumbers)

data attributes are commonly used for a variety of interactions. Typically via javascript. They do not affect anything regarding site behavior and stand as a convenient method to pass data for whatever purpose needed. Here is an article that may clear things up:

http://ejohn.org/blog/html-5-data-attributes/

You can create a data attribute by prefixing data- to any standard attribute safe string (alphanumeric with no spaces or special characters). For example, data-id or in this case data-reactid

When I read in various places that hibernate didn't like you to assign to a collection, I assumed that the safest thing to do would obviously be to make it final like this:

class User {
  private final Set<Role> roles = new HashSet<>();

public void setRoles(Set<Role> roles) {
  this.roles.retainAll(roles);
  this.roles.addAll(roles);
}
}

However, this doesn't work, and you get the dreaded "no longer referenced" error, which is actually quite misleading in this case.

It turns out that hibernate calls your setRoles method AND it wants its special collection class installed here, and won't accept your collection class. This had me stumped for a LONG time, despite reading all the warnings about not assigning to your collection in your set method.

So I changed to this:

public class User {
  private Set<Role> roles = null;

  public void setRoles(Set<Role> roles) {
  if (this.roles == null) {
    this.roles = roles;
  } else {
    this.roles.retainAll(roles);
   this.roles.addAll(roles);
  }
}
}

So that on the first call, hibernate installs its special class, and on subsequent calls you can use the method yourself without wrecking everything. If you want to use your class as a bean, you probably need a working setter, and this at least seems to work.

For me it was really silly I had created a ModelClass file without the .php extension. So calling that was giving model not found. So check the extension has .php

The easiest way to do this is generate a KML file (see http://code.google.com/apis/kml/articles/csvtokml.html for a possible solution). You can then open that up in Google Maps by storing it online and linking to it from Google Maps as described at http://code.google.com/apis/kml/documentation/whatiskml.html

  void* handle = dlopen("myclass.so", RTLD_LAZY);

  MyClass* (*create)();
  void (*destroy)(MyClass*);

  create = (MyClass* (*)())dlsym(handle, "create_object");
  destroy = (void (*)(MyClass*))dlsym(handle, "destroy_object");

  MyClass* myClass = (MyClass*)create();
  myClass->DoSomething();
  destroy( myClass );
}

On Mac OS X, compile with:

g++ -dynamiclib -flat_namespace myclass.cc -o myclass.so
g++ class_user.cc -o class_user

On Linux, compile with:

g++ -fPIC -shared myclass.cc -o myclass.so
g++ class_user.cc -ldl -o class_user

If this were for a plugin system, you would use MyClass as a base class and define all the required functions virtual. The plugin author would then derive from MyClass, override the virtuals and implement create_object and destroy_object. Your main application would not need to be changed in any way.

SELECT id, 
       IF(type = 'P', amount, amount * -1) as amount
FROM report

See http://dev.mysql.com/doc/refman/5.0/en/control-flow-functions.html.

Additionally, you could handle when the condition is null. In the case of a null amount:

SELECT id, 
       IF(type = 'P', IFNULL(amount,0), IFNULL(amount,0) * -1) as amount
FROM report

The part IFNULL(amount,0) means when amount is not null return amount else return 0.

I just used =COUNTIF(Range, "<>") and it counted non-empty cells for me.

In case if you are still stumbling over this question. Nowadays things look nicer with Java 8:

try {
  Files.lines(Paths.get(targetsFile)).forEach(
    s -> {
      System.out.println(s);
      // do more stuff with s
    }
  );
} catch (IOException exc) {
  exc.printStackTrace();
}

Here's the example:

// Test
public void foo() {
    C c = new C();
    A s;
    s = ((A.B)c).get();
    System.out.println(s.getR());
}

// classes
class C {}

class A {
   public class B extends C{
     A get() {return A.this;}
   }
   public String getR() {
     return "This is string";
   }
}

To remove the default MouseOver behaviour on the Button you will need to modify the ControlTemplate. Changing your Style definition to the following should do the trick:

<Style TargetType="{x:Type Button}">
    <Setter Property="Background" Value="Green"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Background="{TemplateBinding Background}" BorderBrush="Black" BorderThickness="1">
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Background" Value="Red"/>
        </Trigger>
    </Style.Triggers>
</Style>

EDIT: It's a few years late, but you are actually able to set the border brush inside of the border that is in there. Idk if that was pointed out but it doesn't seem like it was...

I started having this issue after upgrading from Rails 5.1 to 5.2
It got solved with:

spring stop
spring binstub --all
spring start
rails s

you can use it when you expect a null value in your integer especially when you use CASTING ex:

x= (int)y;

if y = null then you will have an error. you have to use:

x = (int?)y;

The way I cleared my form input values was to add an id to my form tag. Then when I handleSubmit I call this.clearForm()

In the clearForm function I then use document.getElementById("myForm").reset();

import React, {Component } from 'react';
import './App.css';
import Button from './components/Button';
import Input from './components/Input';

class App extends Component {  
  state = {
    item: "", 
    list: []
}

componentDidMount() {
    this.clearForm();
  }

handleFormSubmit = event => {
   this.clearForm()
   event.preventDefault()
   const item = this.state.item

    this.setState ({
        list: [...this.state.list, item],
            })

}

handleInputChange = event => {
  this.setState ({
    item: event.target.value 
  })
}

clearForm = () => {
  document.getElementById("myForm").reset(); 
  this.setState({
    item: ""
  })
}



  render() {
    return (
      <form id="myForm">
      <Input

           name="textinfo"
           onChange={this.handleInputChange}
           value={this.state.item}
      />
      <Button
        onClick={this.handleFormSubmit}
      >  </Button>
      </form>
    );
  }
}

export default App;

#include<string.h>
#include<stdio.h>
int main()
{
    char input[16] = "abc,d";
    char *p;
    p = strtok(input, ",");

    if(p)
    {
    printf("%s\n", p);
    }
    p = strtok(NULL, ",");

    if(p)
           printf("%s\n", p);
    return 0;
}

you can look this program .First you should use the strtok(input, ",").input is the string you want to spilt.Then you use the strtok(NULL, ","). If the return value is true ,you can print the other group.

$.each(myobject, function(key, element) {
    alert('key: ' + key + '\n' + 'value: ' + element);
});

This does the work for me. :)

use str

try:
    some_method()
except Exception as e:
    s = str(e)

Also, most exception classes will have an args attribute. Often, args[0] will be an error message.

It should be noted that just using str will return an empty string if there's no error message whereas using repr as pyfunc recommends will at least display the class of the exception. My take is that if you're printing it out, it's for an end user that doesn't care what the class is and just wants an error message.

It really depends on the class of exception that you are dealing with and how it is instantiated. Did you have something in particular in mind?

Python 3.x version of Etaoin's answer for completeness:

Webkit is a web browser rendering engine used by Safari and Chrome (among others, but these are the popular ones).

The -webkit prefix on CSS selectors are properties that only this engine is intended to process, very similar to -moz properties. Many of us are hoping this goes away, for example -webkit-border-radius will be replaced by the standard border-radius and you won't need multiple rules for the same thing for multiple browsers. This is really the result of "pre-specification" features that are intended to not interfere with the standard version when it comes about.

For your update:...no it's not related to IE really, IE at least before 9 uses a different rendering engine called Trident.

org.apache.http.client.utils.URLEncodedUtils

is a well known library that can do it for you

import org.apache.hc.client5.http.utils.URLEncodedUtils

String url = "http://www.example.com/something.html?one=1&two=2&three=3&three=3a";

List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), Charset.forName("UTF-8"));

for (NameValuePair param : params) {
  System.out.println(param.getName() + " : " + param.getValue());
}

Outputs

one : 1
two : 2
three : 3
three : 3a

This is not directly to your code sample, but in general about the error. I'm writing it here, because Google directs this error to this question, so it may be useful for the other devs.

Another use case when you can receive such error is when you're adding a selector to method in another class, eg:

private class MockTextFieldTarget {
private(set) var didCallDoneAction = false
    @objc func doneActionHandler() {
        didCallDoneAction = true
    }
}

And then in another class:

final class UITextFieldTests: XCTestCase {
    func testDummyCode() {
        let mockTarget = MockTextFieldTarget()
        UIBarButtonItem(barButtonSystemItem: .cancel, target: mockTarget, action: MockTextFieldTarget.doneActionHandler)
        // ... do something ...
    }
}

If in the last line you'd simply call #selector(cancelActionHandler) instead of #selector(MockTextFieldTarget.cancelActionHandler), you'd get

use of unresolved identifier

error.

PHP redirects are better if you can as with the JavaScript one you're causing the client to load the page before the redirect, whereas with the PHP one it sends the proper header.

However the PHP shouldn't go in the <head>, it should go before any output is sent to the client, as to do otherwise will cause errors.

Using <meta> tags have the same issue as Javascript in causing the initial page to load before doing the redirect. Server-side redirects are almost always better, if you can use them.

from the official python tutorial Modules

To speed up loading modules, Python caches the compiled version of each module in the __pycache__ directory under the name module.version.pyc, where the version encodes the format of the compiled file; it generally contains the Python version number. For example, in CPython release 3.6 the compiled version of spam.py would be cached as __pycache__/spam.cpython-36.pyc.

from Python doc Programming FAQs

When a module is imported for the first time (or when the source file has changed since the current compiled file was created) a .pyc file containing the compiled code should be created in a __pycache__ subdirectory of the directory containing the .py file. The .pyc file will have a filename that starts with the same name as the .py file, and ends with .pyc, with a middle component that depends on the particular python binary that created it.

You can also pass git reset --hard a commit reference.

For example:

git checkout branch-name
git reset --hard new-tip-commit

I find I do something like this semi-frequently:

Assuming this history

$ git log --decorate --oneline --graph
* 3daed46 (HEAD, master) New thing I shouldn't have committed to master
* a0d9687 This is the commit that I actually want to be master

# Backup my latest commit to a wip branch
$ git branch wip_doing_stuff

# Ditch that commit on this branch
$ git reset --hard HEAD^

# Now my changes are in a new branch
$ git log --decorate --oneline --graph
* 3daed46 (wip_doing_stuff) New thing I shouldn't have committed to master
* a0d9687 (HEAD, master) This is the commit that I actually want to be master

pip install -U $(pip list --outdated | awk 'NR>2 {print $1}')

For Python 3 you could try using quote instead of quote_plus:

import urllib.parse

print(urllib.parse.quote("http://www.sample.com/"))

Result:

http%3A%2F%2Fwww.sample.com%2F

Or:

from requests.utils import requote_uri
requote_uri("http://www.sample.com/?id=123 abc")

Result:

'https://www.sample.com/?id=123%20abc'

In Java, integer literals are of type int by default. For some other types, you may suffix the literal with a case-insensitive letter like L, D, F to specify a long, double, or float, respectively. Note it is common practice to use uppercase letters for better readability.

The Java Language Specification does not provide the same syntactic sugar for byte or short types. Instead, you may declare it as such using explicit casting:

byte foo = (byte)0;
short bar = (short)0;

In your setLongValue(100L) method call, you don't have to necessarily include the L suffix because in this case the int literal is automatically widened to a long. This is called widening primitive conversion in the Java Language Specification.

Well, you didn't specify which version of .Net you're using.

Assuming you have 3.5, another way is the ElementAt method:

var e = enumerable.ElementAt(0);

For TFS 2013:

Start in VisualStudio-Team Explorer, in the PendingChanges Dialog undo the Changes whith the state [add], which should be ignored.

Visual Studio will detect the Add(s) again. Click On "Detected: x add(s)"-in Excluded Changes

In the opened "Promote Cadidate Changes"-Dialog You can easy exclude Files and Folders with the Contextmenu. Options are:

• Ignore this item
• Ignore by extension
• Ignore by file name
• Ignore by ffolder (yes ffolder, TFS 2013 Update 4/Visual Studio 2013 Premium Update 4)

Don't forget to Check In the changed .tfignore-File.

For VS 2015/2017:

The same procedure: In the "Excluded Changes Tab" in TeamExplorer\Pending Changes click on Detected: xxx add(s)

The "Promote Candidate Changes" Dialog opens, and on the entries you can Right-Click for the Contextmenu. Typo is fixed now :-)

This is a bit dated but there may be others looking for answers to the same question. You should think about what protection spaces make sense for your APIs. For example, you may want to identify and authenticate client application access to your APIs to restrict their use to known, registered client applications. In this case, you can use the Basic authentication scheme with the client identifier as the user-id and client shared secret as the password. You don't need proprietary authentication schemes just clearly identify the one(s) to be used by clients for each protection space. I prefer only one for each protection space but the HTTP standards allow both multiple authentication schemes on each WWW-Authenticate header response and multiple WWW-Authenticate headers in each response; this will be confusing for API clients which options to use. Be consistent and clear then your APIs will be used.

There are ways you can check even if you are not a paid user. You can confirm TeamID from Xcode. [Build setting] Displayed on tooltip of development team.

Pure JS with DeltaX and DeltaY

This DeltaX and DeltaY as suggested by a comment in the accepted answer to avoid the frustrating experience when trying to click and get a drag operation instead due to a one tick mousemove.

    deltaX = deltaY = 2;//px
    var element = document.getElementById('divID');
    element.addEventListener("mousedown", function(e){
        if (typeof InitPageX == 'undefined' && typeof InitPageY == 'undefined') {
            InitPageX = e.pageX;
            InitPageY = e.pageY;
        }

    }, false);
    element.addEventListener("mousemove", function(e){
        if (typeof InitPageX !== 'undefined' && typeof InitPageY !== 'undefined') {
            diffX = e.pageX - InitPageX;
            diffY = e.pageY - InitPageY;
            if (    (diffX > deltaX) || (diffX < -deltaX)
                    || 
                    (diffY > deltaY) || (diffY < -deltaY)   
                    ) {
                console.log("dragging");//dragging event or function goes here.
            }
            else {
                console.log("click");//click event or moving back in delta goes here.
            }
        }
    }, false);
    element.addEventListener("mouseup", function(){
        delete InitPageX;
        delete InitPageY;
    }, false);

   element.addEventListener("click", function(){
        console.log("click");
    }, false);

If data already exists in the column you should do:

ALTER TABLE tbl_name ALTER COLUMN col_name TYPE integer USING col_name::integer;

As pointed out by @nobu and @jonathan-porter in comments to @derek-kromm's answer.

I've experienced a problem with length of None, which leads to Internal Server Error: TypeError: object of type 'NoneType' has no len()

My workaround is just displaying 0 if object is None and calculate length of other types, like list in my case:

{{'0' if linked_contacts == None else linked_contacts|length}}

It seems like you are not going to your specific folder. For example, if I am working on a project named bugsBunny and it is saved in the folder d:/work:code , so first you have to go to that folder using cd d:/work/code/bugsBunny , then after that you can continue using your git commands.

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

If you don't want to use the SQL syntax (which you are forced to), then switch to a framework like Entity Framework or Linq-to-SQL where you don't write the SQL statements yourself.

You can very easily use this to re-use the value of the variable in another function.

// Use this in source window.var1= oEvent.getSource().getBindingContext();

// Get value of var1 in destination var var2= window.var1;

just copy the image and then paste it, you will get the output

Try killing port 8600 with this command:

fuser -k 8600/tcp

That fixed it for me.

Comparisons are case insensitive when the column uses a collation which ends with _ci (such as the default latin1_general_ci collation) and they are case sensitive when the column uses a collation which ends with _cs or _bin (such as the utf8_unicode_cs and utf8_bin collations).

Check collation

You can check your server, database and connection collations using:

mysql> show variables like '%collation%';
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | utf8_general_ci   |
| collation_database   | latin1_swedish_ci |
| collation_server     | latin1_swedish_ci |
+----------------------+-------------------+

and you can check your table collation using:

mysql> SELECT table_schema, table_name, table_collation 
       FROM information_schema.tables WHERE table_name = `mytable`;
+----------------------+------------+-------------------+
| table_schema         | table_name | table_collation   |
+----------------------+------------+-------------------+
| myschema             | mytable    | latin1_swedish_ci |

Change collation

You can change your database, table, or column collation to something case sensitive as follows:

-- Change database collation
ALTER DATABASE `databasename` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;

-- or change table collation
ALTER TABLE `table` CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;

-- or change column collation
ALTER TABLE `table` CHANGE `Value` 
    `Value` VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_bin;

Your comparisons should now be case-sensitive.

Use the viewControllers property of the UINavigationController. Example code:

// Inside another ViewController
NSArray *viewControllers = self.navigationController.viewControllers;
UIViewController *rootViewController = [viewControllers objectAtIndex:viewControllers.count - 2];

This is the standard way of getting the "back" view controller. The reason objectAtIndex:0 works is because the view controller you're trying to access is also the root one, if you were deeper in the navigation, the back view would not be the same as the root view.

the simple and easy way to do that is use on event:

$('body').on('click','#element',function(){
    //somthing
});

but we can say this is not the best way to do this. I suggest a another way to do this is use clone() method instead of using dynamic html. Write some html in you file for example:

<div id='div1'></div>

Now in the script tag make a clone of this div then all the properties of this div would follow with new element too. For Example:

var dynamicDiv = jQuery('#div1').clone(true);

Now use the element dynamicDiv wherever you want to add it or change its properties as you like. Now all jQuery functions will work with this element

core.autocrlf=input is the right setting for what you want, but you might have to do a git update-index --refresh and/or a git reset --hard for the change to take effect.

With core.autocrlf set to input, git will not apply newline-conversion on check-out (so if you have LF in the repo, you'll get LF), but it will make sure that in case you mess up and introduce some CRLFs in the working copy somehow, they won't make their way into the repo.

Like others have mentioned, I think of roles as containers for more granular permissions.

Although I found the Hierarchy Role implementation to be lacking fine control of these granular permission.
So I created a library to manage the relationships and inject the permissions as granted authorities in the security context.

I may have a set of permissions in the app, something like CREATE, READ, UPDATE, DELETE, that are then associated with the user's Role.

Or more specific permissions like READ_POST, READ_PUBLISHED_POST, CREATE_POST, PUBLISH_POST

These permissions are relatively static, but the relationship of roles to them may be dynamic.

Example -

@Autowired 
RolePermissionsRepository repository;

public void setup(){
  String roleName = "ROLE_ADMIN";
  List<String> permissions = new ArrayList<String>();
  permissions.add("CREATE");
  permissions.add("READ");
  permissions.add("UPDATE");
  permissions.add("DELETE");
  repository.save(new RolePermissions(roleName, permissions));
}

You may create APIs to manage the relationship of these permissions to a role.

If you don't mind introducing a dependency, CliWrap can simplify this for you:

using CliWrap;
using CliWrap.Buffered;

var result = await Cli.Wrap("target.exe")
   .WithArguments("arguments")
   .ExecuteBufferedAsync();

var stdout = result.StandardOutput;

You could use

EDIT: This works for MSSQL 2005+, but I see that you now have clarified that you are working on MSSQL 2000. I'll leave this here for reference.

The content inside strings in Golang can be compared using == operator. If the results are not as expected there may be some hidden characters like \n, \r, spaces, etc. So as a general rule of thumb, try removing those using functions provided by strings package in golang.

For Instance, spaces can be removed using strings.TrimSpace function. You can also define a custom function to remove any character you need. strings.TrimFunc function can give you more power.

The naive algorithm, which is what you've got once you correct it as noted in comments, is O(n^3).

There do exist algorithms that reduce this somewhat, but you're not likely to find an O(n^2) implementation. I believe the question of the most efficient implementation is still open.

I hope this will give you the idea.

This is short, yet efficient and proven approach:

location ~ (patternOne|patternTwo){ #rules etc. }

So one can easily have multiple patterns with simple pipe syntax pointing to the same location block / rules.

Four methods using wget, urllib and request.

    r = requests.get(url, stream=True)
    with open(image_name, 'wb') as f:
        for chunk in r.iter_content():
            f.write(chunk)

def testRequest2():
    image_name = 'test2.jpg'
    r = requests.get(url)
    i = Image.open(StringIO(r.content))
    i.save(image_name)

def testUrllib():

    testfile = urllib.URLopener()
    testfile.retrieve(url, image_name)

def testwget():
    image_name = 'test4.jpg'
    wget.download(url, image_name)

Officially not.

But here's a patch: http://rt.openssl.org/Ticket/Display.html?id=2651&user=guest&pass=guest

I've personally never seen .cc in any project that I've worked on, but in all technicality the compiler won't care.

Who will care is the developers working on your source, so my rule of thumb is to go with what your team is comfortable with. If your "team" is the open source community, go with something very common, of which .cpp seems to be the favourite.

FUNCTION UNIQUE2(
 seq IN NUMBER
) RETURN VARCHAR2
AS
 i NUMBER := seq;
 s VARCHAR2(9);
 r NUMBER(2,0);
BEGIN
  WHILE i > 0 LOOP
    r := MOD( i, 36 );
    i := ( i - r ) / 36;
    IF ( r < 10 ) THEN
      s := TO_CHAR(r) || s;
    ELSE
      s := CHR( 55 + r ) || s;
    END IF;
  END LOOP;
  RETURN 'ID'||LPAD( s, 14, '0' );
END;

Do you realize, that CLAMP255 returns 0 for v < 0 and 255 for v >= 0?
IMHO, CLAMP255 should be defined as:

#define CLAMP255(v) (v > 255 ? 255 : (v < 0 ? 0 : v))

Difference: If v is not greater than 255 and not less than 0: return v instead of 255

Java 8 Native

java.time makes it simple since Java 8. And thread safe.

ZonedDateTime.now( ZoneOffset.UTC ).format( DateTimeFormatter.ISO_INSTANT )

Result: 2015-04-14T11:07:36.639Z

You may be tempted to use lighter Temporal such as Instant or LocalDateTime, but they lacks formatter support or time zone data. Only ZonedDateTime works out of the box.

By tuning or chaining the options / operations of ZonedDateTime and DateTimeFormatter, you can easily control the timezone and precision, to a certain degree:

ZonedDateTime.now( ZoneId.of( "Europe/Paris" ) )
             .truncatedTo( ChronoUnit.MINUTES )
             .format( DateTimeFormatter.ISO_DATE_TIME )

Result: 2015-04-14T11:07:00+01:00[Europe/Paris]

Refined requirements, such as removing the seconds part, must still be served by custom formats or custom post process.

.format( DateTimeFormatter.ISO_LOCAL_DATE_TIME ) // 2015-04-14T11:07:00
.format( DateTimeFormatter.ISO_LOCAL_DATE ) // 2015-04-14
.format( DateTimeFormatter.ISO_LOCAL_TIME ) // 11:07:00
.format( DateTimeFormatter.ofPattern( "yyyy-MM-dd HH:mm" ) ) // 2015-04-14 11:07

For Java 6 & 7, you may consider back-ports of java.time such as ThreeTen-Backport, which also has an Android port. Both are lighter than Joda, and has learned from Joda's experience - esp. considering that java.time is designed by Joda's author.

Try this:

body { 
    min-height:100%; 
    background:red; 
} 

#some_div {
    min-height:100%; 
    background:black; 
} 

IE6 and earlier versions do not support the min-height property.

I think the problem is that when you tell the body to have a height of 100%, it's background can only be as tall as the hieght of one browser "viewport" (the viewing area that excludes the browsers toolbars & statusbars & menubars and the window edges). If the content is taller than one viewport, it will overflow the height devoted to the background.

This min-height property on the body should FORCE the background to be at least as tall as one viewport if your content does not fill one whole page down to the bottom, yet it should also let it grow downwards to encompass more interior content.

I think you should not rely on the implicit conversion. It is a bad practice.

Instead you should try like this:

datenum >= to_date('11/26/2013','mm/dd/yyyy')

or like

datenum >= date '2013-09-01'

At the moment (with the latest changes to Swift), NSDate.date() is not longer available.

Instead you just need to initialize NSDate and it gets the current date and time.
To try it, in a playground:

var d = NSDate()
d

and you will get:

Oct 22, 2014, 12:20 PM"  

You need to initialize it first:

p = Pump().getPumps()

For a dynamic approach, if your labels are always in front of your text areas:

$(object).prev("label").text(charsleft);

Warning: Note that English is not restricted to just A-Z.

Try this to remove everything except a-z, A-Z and 0-9:

$result = preg_replace("/[^a-zA-Z0-9]+/", "", $s);

If your definition of alphanumeric includes letters in foreign languages and obsolete scripts then you will need to use the Unicode character classes.

Try this to leave only A-Z:

$result = preg_replace("/[^A-Z]+/", "", $s);

The reason for the warning is that words like résumé contains the letter é that won't be matched by this. If you want to match a specific list of letters adjust the regular expression to include those letters. If you want to match all letters, use the appropriate character classes as mentioned in the comments.

To modify session data from the server after page creation you would need to use AJAX or even JQuery to get the job done. Both of them can make a connection to the server to modify session data and get returned data back from that connection.

<?php
session_start();
$_SESSION['usedData'] = "Some Value"; //setting for now since it doesn't exist
?>
<!DOCTYPE html>

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Modifying PHP Session Data</title>
        <script type='text/javascript'>
            var usedData = '<?php echo $_SESSION['usedData']; ?>';
            var oldDataValue = null;

            /* If function used, sends new data from input field to the
               server, then gets response from server if any. */

            function modifySession () {
                var newValue = document.getElementById("newValueData").value;

                /* You could always check the newValue here before making
                   the request so you know if its set or needs filtered. */

                var xhttp = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP");

                xhttp.onreadystatechange = function () {
                    if (this.readyState == 4 && this.status == 200) {
                        oldDataValue = usedData;
                        usedData = this.responseText; //response from php script
                        document.getElementById("sessionValue").innerHTML = usedData;
                        document.getElementById("sessionOldValue").innerHTML = oldDataValue;
                    }
                };

            xhttp.open("GET", "modifySession.php?newData="+newValue, true);
            xhttp.send(); 
            }
        </script>
    </head>
    <body>
        <h1><p>Modify Session</p></h1>

        Current Value: <div id='sessionValue' style='display:inline'><?php echo $_SESSION['usedData']; ?></div><br/>
        Old Value: <div id='sessionOldValue' style='display:inline'><?php echo $_SESSION['usedData']; ?></div><br/>

        New Value: <input type='text' id='newValueData' /><br/>
        <button onClick='modifySession()'>Change Value</button>
   </body>
</html>

Now we need to make a small php script called modifySession.php to make changes to session data and post data back if necessary.

<?php
session_start();
$_SESSION['usedData'] = $_GET['newData']; //filter if necessary
echo $_SESSION['usedData']; // Post results back if necessary
?>

This should achieve the desired results you are looking for by modifying the session via server side using PHP/AJAX.

There's no easy way of doing this, other than doing something like class="lastCell" on the last td in each tr, and then setting your css up like this:

#table td {
    border-right: 5px solid red
}

.lastCell {
    border-right: none;
}

Just adding something to the Tung's answer (you need to use rstrip('/') to be more of the safer side if you're on a unix box).

>>> input = "../data/replies/"
>>> os.path.dirname(input.rstrip('/'))
'../data'
>>> input = "../data/replies"
>>> os.path.dirname(input.rstrip('/'))
'../data'

But, if you don't use rstrip('/'), given your input is

>>> input = "../data/replies/"

would output,

>>> os.path.dirname(input)
'../data/replies'

which is probably not what you're looking at as you want both "../data/replies/" and "../data/replies" to behave the same way.

Variables:

static variables exist for the "lifetime" of the translation unit that it's defined in, and:

• If it's in a namespace scope (i.e. outside of functions and classes), then it can't be accessed from any other translation unit. This is known as "internal linkage" or "static storage duration". (Don't do this in headers except for constexpr. Anything else, and you end up with a separate variable in each translation unit, which is crazy confusing)
• If it's a variable in a function, it can't be accessed from outside of the function, just like any other local variable. (this is the local they mentioned)
• class members have no restricted scope due to static, but can be addressed from the class as well as an instance (like std::string::npos). [Note: you can declare static members in a class, but they should usually still be defined in a translation unit (cpp file), and as such, there's only one per class]

locations as code:

static std::string namespaceScope = "Hello";
void foo() {
    static std::string functionScope= "World";
}
struct A {
   static std::string classScope = "!";
};

Before any function in a translation unit is executed (possibly after main began execution), the variables with static storage duration (namespace scope) in that translation unit will be "constant initialized" (to constexpr where possible, or zero otherwise), and then non-locals are "dynamically initialized" properly in the order they are defined in the translation unit (for things like std::string="HI"; that aren't constexpr). Finally, function-local statics will be initialized the first time execution "reaches" the line where they are declared. All static variables all destroyed in the reverse order of initialization.

The easiest way to get all this right is to make all static variables that are not constexpr initialized into function static locals, which makes sure all of your statics/globals are initialized properly when you try to use them no matter what, thus preventing the static initialization order fiasco.

T& get_global() {
    static T global = initial_value();
    return global;
}

Be careful, because when the spec says namespace-scope variables have "static storage duration" by default, they mean the "lifetime of the translation unit" bit, but that does not mean it can't be accessed outside of the file.

Functions

Significantly more straightforward, static is often used as a class member function, and only very rarely used for a free-standing function.

A static member function differs from a regular member function in that it can be called without an instance of a class, and since it has no instance, it cannot access non-static members of the class. Static variables are useful when you want to have a function for a class that definitely absolutely does not refer to any instance members, or for managing static member variables.

struct A {
    A() {++A_count;}
    A(const A&) {++A_count;}
    A(A&&) {++A_count;}
    ~A() {--A_count;}

    static int get_count() {return A_count;}
private:
    static int A_count;
}

int main() {
    A var;

    int c0 = var.get_count(); //some compilers give a warning, but it's ok.
    int c1 = A::get_count(); //normal way
}

A static free-function means that the function will not be referred to by any other translation unit, and thus the linker can ignore it entirely. This has a small number of purposes:

• Can be used in a cpp file to guarantee that the function is never used from any other file.
• Can be put in a header and every file will have it's own copy of the function. Not useful, since inline does pretty much the same thing.
• Speeds up link time by reducing work
• Can put a function with the same name in each translation unit, and they can all do different things. For instance, you could put a static void log(const char*) {} in each cpp file, and they could each all log in a different way.

1. You get programmable vertex and pixel shaders that allow execution of code directly on the GPU to manipulate the buffers that are to be drawn. These languages (i.e. OpenGL's GL Shader Lang and High Level Shader Lang and DirectX's equivalents ), are C style syntax, and really easy to use. Some examples of HLSL can be found here for XNA game studio and Direct X. I don't have any decent GLSL references, but I'm sure there are a lot around. These shader languages give an immense amount of power to manipulate what gets drawn at a per-vertex or per-pixel level, directly on the graphics card, making things like shadows, lighting, and bloom really easy to implement.
2. The second thing that comes to mind is using openCL to code for the new lines of general purpose GPU's. I'm not sure how to use this, but my understanding is that openCL gives you the beginnings of being able to access processors on both the graphics card and normal cpu. This is not mainstream technology yet, and seems to be driven by Apple.
3. CUDA seems to be a hot topic. CUDA is nVidia's way of accessing the GPU power. Here are some intros

sudo yum install fontconfig freetype libfreetype.so.6 libfontconfig.so.1 libstdc++.so.6

Relying on compiler optimizations is fragile. The benchmarks linked in the accepted answer and numbers given by Antoine-tran are not to be trusted. Andrew Hare makes the mistake of including a call to repr in his methods. That slows all the methods equally but obscures the real penalty in constructing the string.

Use join. It's very fast and more robust.

To do this for oracle sql, the syntax would be:

for this example, I look for the second '-' and take the substring to the end

System.IO.Path.GetTempPath() is just a wrapper for a native call to GetTempPath(..) in Kernel32.

Have a look at http://msdn.microsoft.com/en-us/library/aa364992(VS.85).aspx

Copied from that page:

The GetTempPath function checks for the existence of environment variables in the following order and uses the first path found:

• The path specified by the TMP environment variable.
• The path specified by the TEMP environment variable.
• The path specified by the USERPROFILE environment variable.
• The Windows directory.

It's not entirely clear to me whether "The Windows directory" means the temp directory under windows or the windows directory itself. Dumping temp files in the windows directory itself sounds like an undesirable case, but who knows.

So combining that page with your post I would guess that either one of the TMP, TEMP or USERPROFILE variables for your Administrator user points to the windows path, or else they're not set and it's taking a fallback to the windows temp path.

Also pass the --execute flag to generate the output cells

jupyter nbconvert --execute --to html notebook.ipynb
jupyter nbconvert --execute --to pdf notebook.ipynb

The best practice is to keep the output out of the notebook for version control, see: Using IPython notebooks under version control

But then, if you don't pass --execute, the output won't be present in the HTML, see also: How to run an .ipynb Jupyter Notebook from terminal?

For an HTML fragment without header: How to export an IPython notebook to HTML for a blog post?

Tested in Jupyter 4.4.0.

As @martin and this answer explained, it is complicated. There is no bullet-proof way of getting the client's ip address.

The best that you can do is to try to parse "X-Forwarded-For" and rely on request.getRemoteAddr();

public static String getClientIpAddress(HttpServletRequest request) {
    String xForwardedForHeader = request.getHeader("X-Forwarded-For");
    if (xForwardedForHeader == null) {
        return request.getRemoteAddr();
    } else {
        // As of https://en.wikipedia.org/wiki/X-Forwarded-For
        // The general format of the field is: X-Forwarded-For: client, proxy1, proxy2 ...
        // we only want the client
        return new StringTokenizer(xForwardedForHeader, ",").nextToken().trim();
    }
}

bool isMultiple = a % b == 0;

This will be true if a is a multiple of b

I guess you want to get number(s) from the string. In which case, you can use the following:

// Returns an array of numbers located in the string
function get_numbers(input) {
    return input.match(/[0-9]+/g);
}

var first_test = get_numbers('something102');
var second_test = get_numbers('something102or12');
var third_test = get_numbers('no numbers here!');

alert(first_test); // [102]
alert(second_test); // [102,12]
alert(third_test); // null

For Ubuntu 18.04

npm install latest-version

I hope its for you also

You have a misplaced closing brace before the return statement.

LL(1) grammar is Context free unambiguous grammar which can be parsed by LL(1) parsers.

In LL(1)

• First L stands for scanning input from Left to Right. Second L stands for Left Most Derivation. 1 stands for using one input symbol at each step.

For Checking grammar is LL(1) you can draw predictive parsing table. And if you find any multiple entries in table then you can say grammar is not LL(1).

Their is also short cut to check if the grammar is LL(1) or not . Shortcut Technique

Please NOTE that this procedure of adding the reporting services described by @Rich Shealer above will be iterated every time you start a different project. In order to avoid that:

1. If you may need to set up a different computer (eg, at home without internet), then keep your downloaded installers from the marketplace somewhere safe, ie:

   • Microsoft.DataTools.ReportingServices.vsix, and
   • Microsoft.RdlcDesigner.vsix

2. Fetch the following libraries from the packages or bin folder of the application you have created with reporting services in it:

   • Microsoft.ReportViewer.Common.dll
   • Microsoft.ReportViewer.DataVisualization.dll
   • Microsoft.ReportViewer.Design.dll
   • Microsoft.ReportViewer.ProcessingObjectModel.dll
   • Microsoft.ReportViewer.WinForms.dll

3. Install the 2 components from 1 above

4. Add the dlls from 2 above as references (Project>References>Add...)
5. (Optional) Add Reporting tab to the toolbar
6. Add Items to Reporting tab
7. Browse to the bin folder or where you have the above dlls and add them

You are now good to go! ReportViewer icon will be added to your toolbar, and you will also now find Report and ReportWizard templates added to your Common list of templates when you want to add a New Item... (Report) to your project

NB: When set up using Nuget package manager, the Report and ReportWizard templates are grouped under Reporting. Using my method described above however does not add the Reporting grouping in installed templates, but I dont think it is any trouble given that it enables you to quickly integrate rdlc without internet and without downloading what you already have from Nuget every time!

UPDATE (SELECT T.FIELD A, S.FIELD B
FROM TABLE_T T INNER JOIN TABLE_S S
ON T.ID = S.ID)
SET B = A;

A and B are alias fields, you do not need to point the table.

I'm running Windows 7 with git bash console. The above commands wouldn't work for me.

So I did it via Windows Explorer. I checked show hidden files, went to my projects directory and manually deleted the .git folder. Then back in the command line I checked by running git status.

Which returned...

fatal: Not a git repository (or any of the parent directories): .git

Which is exactly the result I wanted. It returned that the directory is not a git repository (anymore!).

If you're using the resource routes, then in the HTML body of the form, you can use method_field helper like this:

<form>
  {{ csrf_field() }}
  {{ method_field('PUT') }}
  <!-- ... -->
</form>

It will create hidden form input with method type, that is correctly interpereted by Laravel 5.5+.

Since Laravel 5.6 you can use following Blade directives in the templates:

<form>
  @method('put')
  @csrf
  <!-- ... -->
</form>

Hope this might help someone in the future.

Matheus de Oliveira created handy functions for JSON CRUD operations in postgresql. They can be imported using the \i directive. Notice the jsonb fork of the functions if jsonb if your data type.

9.3 json https://gist.github.com/matheusoliveira/9488951

9.4 jsonb https://gist.github.com/inindev/2219dff96851928c2282

To check the size of all of the directories within a directory, you can use:

du -h --max-depth=1

You can also use @mock.patch.object:

Let's say a module my_module.py uses pandas to read from a database and we would like to test this module by mocking pd.read_sql_table method (which takes table_name as argument).

What you can do is to create (inside your test) a db_mock method that returns different objects depending on the argument provided:

def db_mock(**kwargs):
    if kwargs['table_name'] == 'table_1':
        # return some DataFrame
    elif kwargs['table_name'] == 'table_2':
        # return some other DataFrame

In your test function you then do:

import my_module as my_module_imported

@mock.patch.object(my_module_imported.pd, "read_sql_table", new_callable=lambda: db_mock)
def test_my_module(mock_read_sql_table):
    # You can now test any methods from `my_module`, e.g. `foo` and any call this 
    # method does to `read_sql_table` will be mocked by `db_mock`, e.g.
    ret = my_module_imported.foo(table_name='table_1')
    # `ret` is some DataFrame returned by `db_mock`

Probably late but here is a plugin that can do the job : http://multi-level-push-menu.make.rs/

Also v2 can use mobile gesture such as swipe ;)

In Eztrieve it's really easy, below is an example how you could code it:

You are calling the one.start() method in the run method of your Thread. But the run method will only be called when a thread is already started. Do this instead:

one = new Thread() {
    public void run() {
        try {
            System.out.println("Does it work?");

            Thread.sleep(1000);

            System.out.println("Nope, it doesnt...again.");
        } catch(InterruptedException v) {
            System.out.println(v);
        }
    }  
};

one.start();

If you are aiming for maximum browser support, modern approach is to place button in a div with display:flex; and flex-direction:row; The same trick will work for height with flex-direction:column; or both height and width(will require 2 divs)

You can use sum() with a generator expression here. The generator expression will be [1, 1, ...] up to the length of the file. Then we call sum() to add them all together, to get the total count.

with open('text.txt') as myfile:
    count = sum(1 for line in myfile)

It seems by what you have tried that you don't want to include empty lines. You can then do:

with open('text.txt') as myfile:
    count = sum(1 for line in myfile if line.rstrip('\n'))

Just to phrase things differently from the great answers above, as that has helped me get an intuitive understanding of negative margins:

A negative margin on an element allows it to eat up the space of its parent container.

Adding a (positive) margin on the bottom doesn't allow the element to do that - it only pushes back whatever element is below.

Upgrading to Snow Leopard won't solve the your primary problem of keeping PHP up to date. Apple doesn't always keep the third party software that it bundles up to date with OS updates. And relying on Apple to get you the bug fix / security update you need is asking for trouble.

Additionally, I would recommend installing through MacPorts (and doing the config necessary to use it instead of Apple's PHP) rather than try to upgrade the Apple supplied PHP in place. Anything you do to /usr/bin risks being overwritten by some future Apple update.

[updating in response to more details in the edited question]

The problem you're running into is that, once a page is modified by ajax requests, the current HTML exists only inside the browser's DOM-- there's no longer any independent source HTML that you can validate other than what you can pull out of the DOM.

As you've observed, IE's DOM stores tags in upper case, fixes up unclosed tags, and makes lots of other alterations to the HTML it got originally. This is because browsers are generally very good at taking HTML with problems (e.g. unclosed tags) and fixing up those problems to display something useful to the user. Once the HTML has been canonicalized by IE, the original source HTML is essentially lost from the DOM's perspective, as far as I know.

Firefox most likley makes fewer of these changes, so Firebug is probably your better bet.

A final (and more labor-intensive) option may work for pages with simple ajax alterations, e.g. fetching some HTML from the server and importing this into the page inside a particular element. In that case, you can use fiddler or similar tool to manually stitch together the original HTML with the Ajax HTML. This is probably more trouble than it's worth, and is error prone, but it's one more possibility.

[Original response here to the original question]

Fiddler (http://www.fiddlertool.com/) is a free, browser-independent tool which works very well to fetch the exact HTML received by a browser. It shows you exact bytes on the wire as well as decoded/unzipped/etc content which you can feed into any HTML analysis tool. It also shows headers, timings, HTTP status, and lots of other good stuff.

You can also use fiddler to copy and rebuild requests if you want to test how a server responds to slightly different headers.

Fiddler works as a proxy server, sitting in between your browser and the website, and logs traffic going both ways.

The above answers provided are perfect. The LF(\n), CR(\r) and CRLF(\r\n) characters are platform dependent. However, the interpretation for these characters is not only defined by the platforms but also the console that you are using. In Intellij console (Windows), this \r character in this statement System.out.print("Happ\ry"); produces the output y. But, if you use the terminal (Windows), you will get yapp as the output.

You have to use builder.setSound

Intent notificationIntent = new Intent(MainActivity.this, MainActivity.class);  

                PendingIntent contentIntent = PendingIntent.getActivity(MainActivity.this, 0, notificationIntent,   
                        PendingIntent.FLAG_UPDATE_CURRENT);  

                builder.setContentIntent(contentIntent);  
                builder.setAutoCancel(true);
                builder.setLights(Color.BLUE, 500, 500);
                long[] pattern = {500,500,500,500,500,500,500,500,500};
                builder.setVibrate(pattern);
                builder.setStyle(new NotificationCompat.InboxStyle());
                 Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
                    if(alarmSound == null){
                        alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
                        if(alarmSound == null){
                            alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
                        }
                    }

                // Add as notification  
                NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);  
             builder.setSound(alarmSound);
                manager.notify(1, builder.build());

If you don't have the Android SDK installed, like in some test scenarios, you can get the package name using the following bash method:

getAppIdFromApk() {
  local apk_path="$1"

  # regular expression (required)
  local re="^\"L.*/MainActivity;"
  # sed substitute expression
  local se="s:^\"L\(.*\)/MainActivity;:\1:p"
  # tr expression
  local te=' / .';

  local app_id="$(unzip -p $apk_path classes.dex | strings | grep -Eo $re | sed -n -e $se | tr $te)"

  echo "$app_id"
}

Tested on a mac. 'strings' and 'unzip' are standard on most linux's, so should work on linux too.

Alternatively, you can bring variables in from the outside scope by using closures with the use keyword.

$myVar = "foo";
$myFunction = function($arg1, $arg2) use ($myVar)
{
 return $arg1 . $myVar . $arg2;
};

This happenes might be because you ran out of disk storage and the mysql files and starting files got corrupted

The solution to be tried as below

First we will move the tmp file to somewhere with larger space

Step 1: Copy your existing /etc/my.cnf file to make a backup

cp /etc/my.cnf{,.back-`date +%Y%m%d`}

Step 2: Create your new directory, and set the correct permissions

mkdir /home/mysqltmpdir
chmod 1777 /home/mysqltmpdir

Step 3: Open your /etc/my.cnf file

nano /etc/my.cnf

Step 4: Add below line under the [mysqld] section and save the file

tmpdir=/home/mysqltmpdir

Secondly you need to remove or error files and logs from the /var/lib/mysql/ib_* that means to remove anything that starts by "ib"

rm /var/lib/mysql/ibdata1 and rm /var/lib/mysql/ibda.... and so on

Thirdly you will need to make sure that there is a pid file available to have the database to write in

Step 1 you need to edit /etc/my.cnf

pid-file= /var/run/mysqld/mysqld.pid 

Step 2 create the directory with the file to point to

 mkdir /var/run/mysqld
 touch /var/run/mysqld/mysqld.pid
 chown -R mysql:mysql /var/run/mysqld

Last step restart mysql server

/etc/init.d/mysql restart

Try this:

private int hour;
public int Hour
{
    get { return hour; }
    set
    {
        //make sure hour is positive
        if (value < MIN_HOUR)
        {
            hour = 0;
            MessageBox.Show("Hour value " + value.ToString() + " cannot be negative. Reset to " + MIN_HOUR.ToString(),
            "Invalid Hour", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
        }
        else
        {
            //take the modulus to ensure always less than 24 hours
            //works even if the value is already within range, or value equal to 24
            hour = value % MAX_HOUR;
        }
    }
}

The test has to be done on a page that queries a database so yes typically that is a login page because it's the page that can do the most harm but could be an unsecure page as well.

Generally you would have your database queries behind a secure login but if you just have a listing of items or something that you don't care if the world sees a hacker could append some sql injection to the end of the querystring.

The key with SQL Injection is the person doing the injection would have to know that your querying a database so if your not querying a database then no sql inject can be done. If your form is submitting to a database then yes they could SQL Inject that. It's always good practice to use either stored procedures to select/insert/update/delete or make sure you prepare or escape out all the statements that will be hitting the database.

Add an event for KeyPressed.

private void jTextField1KeyPressed(java.awt.event.KeyEvent evt) {
  if(evt.getKeyCode() == KeyEvent.VK_ENTER) {
      // Enter was pressed. Your code goes here.
   }
} 

ViewResult is a subclass of ActionResult. The View method returns a ViewResult. So really these two code snippets do the exact same thing. The only difference is that with the ActionResult one, your controller isn't promising to return a view - you could change the method body to conditionally return a RedirectResult or something else without changing the method definition.

Add position: relative to .outside. (https://developer.mozilla.org/en-US/docs/CSS/position)

Elements that are positioned relatively are still considered to be in the normal flow of elements in the document. In contrast, an element that is positioned absolutely is taken out of the flow and thus takes up no space when placing other elements. The absolutely positioned element is positioned relative to nearest positioned ancestor. If a positioned ancestor doesn't exist, the initial container is used.

The "initial container" would be <body>, but adding the above makes .outside positioned.

Though this aims to run jobs beside a running process in a container via Docker's exec interface, this may be of interest for you.

I've written a daemon that observes containers and schedules jobs, defined in their metadata, on them. Example:

version: '2'

services:
  wordpress:
    image: wordpress
  mysql:
    image: mariadb
    volumes:
      - ./database_dumps:/dumps
    labels:
      deck-chores.dump.command: sh -c "mysqldump --all-databases > /dumps/dump-$$(date -Idate)"
      deck-chores.dump.interval: daily

'Classic', cron-like configuration is also possible.

Here are the docs, here's the image repository.

If using jruby, here is a code snippet to return an array of all tables in a db.

require "rubygems"
require "jdbc/mysql"
Jdbc::MySQL.load_driver
require "java"

def get_database_tables(connection, db_name)
  md = connection.get_meta_data
  rs = md.get_tables(db_name, nil, '%',["TABLE"])

  tables = []
  count = 0
  while rs.next
    tables << rs.get_string(3)
  end #while
  return tables
end

Try this CSS

input[type=checkbox] {width:100px; height:100px;}

Probably the best way to do so is combo of setting a span with a class denoting your formatting then use Jquery .each to do formatting on the spans when the DOM is loaded...

In the case of permission denied error, you just need to go with this command.

sudo pip install virtualenv

sudo before the command will throw away the current user permissions error.

Note: For security risks, You should read piotr comment.

Your query has 8 or possibly even 9 variables, ie. Name, Description etc. But the values, these things ---> '', '%s', '%s', '%s', '%s', '%s', '%s', '%s')", only total 7, the number of variables have to be the same as the values.

I had the same problem but I figured it out. Hopefully it will also work for you.

site-packages is the target directory of manually built Python packages. When you build and install Python packages from source (using distutils, probably by executing python setup.py install), you will find the installed modules in site-packages by default.

There are standard locations:

• Unix (pure)¹: prefix/lib/pythonX.Y/site-packages
• Unix (non-pure): exec-prefix/lib/pythonX.Y/site-packages
• Windows: prefix\Lib\site-packages

¹ Pure means that the module uses only Python code. Non-pure can contain C/C++ code as well.

site-packages is by default part of the Python search path, so modules installed there can be imported easily afterwards.
