<a href="#"><button>Link Text</button></a>

You asked for a link that looks like a button, so use a link and a button :-) This will preserve default browser button styling. The button by itself does nothing, but clicking it activates its parent link.

Demo:

<a href="http://stackoverflow.com"><button>Link Text</button></a>

This is rather late to the party, and not really saying anything that hasn't been already said in one form or another, mostly through links above, but I wanted to give a TL;DR recap to those with less attention span:

The date and time of the go format string is very important. It's how Go knows which field is which. They are generally 1-9 left to right as follows:

• January / Jan / january / jan / 01 / _1 (etc) are for month
• 02 / _2 are for day of month
• 15 / 03 / _3 / PM / P / pm /p are for hour & meridian (3pm)
• 04 / _4 are for minutes
• 05 / _5 are for seconds
• 2006 / 06 are for year
• -0700 / 07:00 / MST are for timezone
• .999999999 / .000000000 etc are for partial seconds (I think the distinction is if trailing zeros are removed)
• Mon / Monday are day of the week (which 01-02-2006 actually was),

So, Don't write "01-05-15" as your date format, unless you want "Month-Second-Hour"

(... again, this was basically a summary of above.)

This way I solved my problem. Hope it helps others. In my case I created a class, a field, their getter & setter and then provide the object instead of string.

Use this

public static class EncryptedData {
    private String encryptedData;

    public String getEncryptedData() {
        return encryptedData;
    }

    public void setEncryptedData(String encryptedData) {
        this.encryptedData = encryptedData;
    }
}

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getEncryptedData().getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;

Instead of this

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;
}

marshaller.setProperty only works on the JAX-B marshaller from Sun. The question was regarding the JAX-B marshaller from SpringSource, which does not support setProperty.

You have to consider the Turkish I problem when comparing characters/ lowercasing / uppercasing:

I suggest to convert to String and use toLowerCase with invariant culture (in most cases at least).

public final static Locale InvariantLocale = new Locale(Empty, Empty, Empty); str.toLowerCase(InvariantLocale)

See similar C# string.ToLower() and string.ToLowerInvariant()

Note: Don't use String.equalsIgnoreCase http://nikolajlindberg.blogspot.co.il/2008/03/beware-of-java-comparing-turkish.html

Building off of ngoozeff's answer, if you want to make a command run completely in the background (i.e., if you want to hide its output and prevent it from being killed when you close its Terminal window), you can do this instead:

cmd="google-chrome";
"${cmd}" &>/dev/null & disown;

• &>/dev/null sets the command’s stdout and stderr to /dev/null instead of inheriting them from the parent process.
• & makes the shell run the command in the background.
• disown removes the “current” job, last one stopped or put in the background, from under the shell’s job control.

In some shells you can also use &! instead of & disown; they both have the same effect. Bash doesn’t support &!, though.

Also, when putting a command inside of a variable, it's more proper to use eval "${cmd}" rather than "${cmd}":

cmd="google-chrome";
eval "${cmd}" &>/dev/null & disown;

If you run this command directly in Terminal, it will show the PID of the process which the command starts. But inside of a shell script, no output will be shown.

Here's a function for it:

#!/bin/bash

# Run a command in the background.
_evalBg() {
    eval "$@" &>/dev/null & disown;
}

cmd="google-chrome";
_evalBg "${cmd}";

Also, see: Running bash commands in the background properly

You can absolutely do that, just remove the @RequestParam annotation, Spring will cleanly bind your request parameters to your class instance:

public @ResponseBody List<MyObject> myAction(
    @RequestParam(value = "page", required = false) int page,
    MyObject myObject)

You can safely delete the WSDL cache files. If you wish to prevent future caching, use:

ini_set("soap.wsdl_cache_enabled", 0);

or dynamically:

$client = new SoapClient('http://somewhere.com/?wsdl', array('cache_wsdl' => WSDL_CACHE_NONE) );

// This code works for images on 2.2, not sure if any other media types

   //Your file path - Example here is "/sdcard/cats.jpg"
   final String filePathThis = imagePaths.get(position).toString();

   MediaScannerConnectionClient mediaScannerClient = new
   MediaScannerConnectionClient() {
    private MediaScannerConnection msc = null;
    {
        msc = new MediaScannerConnection(getApplicationContext(), this);
        msc.connect();
    }

    public void onMediaScannerConnected(){
        msc.scanFile(filePathThis, null);
    }


    public void onScanCompleted(String path, Uri uri) {
        //This is where you get your content uri
            Log.d(TAG, uri.toString());
        msc.disconnect();
    }
   };

For hidden files I had to use the following:

DEL /S /Q /A:H Thumbs.db

Very simple to fix, you just need to turn the parameter to writerow into a list.

for item in RESULTS:
     wr.writerow([item,])

Make sure the file is a recognized type. I had a yaml file open (without the .yaml file extension) and Sublime Text recognized it as Plain Text. Plain Text has no comment method. Switching the file type to YAML made the comment shortcut work.

You missed out omniORB. This is a pretty full CORBA implementation, so you can also use it to talk to other languages that have CORBA support.

You can try popstate event handler, e.g:

window.addEventListener('popstate', function(event) {
    // The popstate event is fired each time when the current history entry changes.

    var r = confirm("You pressed a Back button! Are you sure?!");

    if (r == true) {
        // Call Back button programmatically as per user confirmation.
        history.back();
        // Uncomment below line to redirect to the previous page instead.
        // window.location = document.referrer // Note: IE11 is not supporting this.
    } else {
        // Stay on the current page.
        history.pushState(null, null, window.location.pathname);
    }

    history.pushState(null, null, window.location.pathname);

}, false);

^{Note: For the best results, you should load this code only on specific pages where you want to implement the logic to avoid any other unexpected issues.}

The popstate event is fired each time when the current history entry changes (user navigates to a new state). That happens when user clicks on browser's Back/Forward buttons or when history.back(), history.forward(), history.go() methods are programatically called.

The event.state is property of the event is equal to the history state object.

For jQuery syntax, wrap it around (to add even listener after document is ready):

(function($) {
  // Above code here.
})(jQuery);

See also: window.onpopstate on page load

See also the examples on Single-Page Apps and HTML5 pushState page:

<script>
// jQuery
$(window).on('popstate', function (e) {
    var state = e.originalEvent.state;
    if (state !== null) {
        //load content with ajax
    }
});

// Vanilla javascript
window.addEventListener('popstate', function (e) {
    var state = e.state;
    if (state !== null) {
        //load content with ajax
    }
});
</script>

This should be compatible with Chrome 5+, Firefox 4+, IE 10+, Safari 6+, Opera 11.5+ and similar.

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

INSTALL_FAILED_VERSION_DOWNGRADE

All Android apps have a package name. The package name uniquely identifies the app on the device. If same packageName as app that's already installed on the device then this error Showing .

1. You can uninstall the application from your device first and then install the fresh one .
2. You could simply increase the number by one each time a new version is released.

If you need to get location from an IP address you can use reliable geo ip service, you can get more detail here. It supports IPv6.

As a bonus it allows to check whether ip address is a tor node, public proxy or spammer.

You can use javascript or php as below.

Javascript Code:

$(document).ready(function () {
        $('#btnGetIpDetail').click(function () {
            if ($('#txtIP').val() == '') {
                alert('IP address is reqired');
                return false;
            }
            $.getJSON("http://ip-api.io/json/" + $('#txtIP').val(),
                 function (result) {
                     alert('City Name: ' + result.city)
                     console.log(result);
                 });
        });
    });

Php Code:

$result = json_decode(file_get_contents('http://ip-api.io/json/64.30.228.118'));
var_dump($result);

Output:

    <param-value>
        classpath*:/META-INF/PersistenceContext.xml
    </param-value>

I have initialized my PersistenceContext.xml within <context-param> because all my servlets will be interacting with database in MVC framework.

Howerver,

        <param-value>com.organisation.project.rest</param-value>
    </init-param>

in the aforementioned code, I am configuring jersey and the ApplicationContext.xml only to rest layer. For the same I am using </init-param>

In Java >=8 you could also use the Streaming API:

Optional<String> first = set.stream().findFirst();

(Useful if the Set/List may be empty.)

I had this problem when there were some Unicode characters in my method names (due to, of all things, copy/pasting from a powerpoint file) that Dalvik did not like. You can see this by looking at Logcat output while trying to install the APK.

This was on a real device.

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!

If anyone is interested in a sortable list with a changing index per listitem (1st, 2nd, 3th etc...:

http://jsfiddle.net/aph0c1rL/1/

$(".sortable").sortable(
{
  handle:         '.handle'
, placeholder:    'sort-placeholder'
, forcePlaceholderSize: true
, start: function( e, ui )
{
    ui.item.data( 'start-pos', ui.item.index()+1 );
}
, change: function( e, ui )
  {
      var seq
      , startPos = ui.item.data( 'start-pos' )
      , $index
      , correction
      ;

      // if startPos < placeholder pos, we go from top to bottom
      // else startPos > placeholder pos, we go from bottom to top and we need to correct the index with +1
      //
      correction = startPos <= ui.placeholder.index() ? 0 : 1;

      ui.item.parent().find( 'li.prize').each( function( idx, el )
      {
        var $this = $( el )
        , $index = $this.index()
        ;

        // correction 0 means moving top to bottom, correction 1 means bottom to top
        //
        if ( ( $index+1 >= startPos && correction === 0) || ($index+1 <= startPos && correction === 1 ) )
        {
          $index = $index + correction;
          $this.find( '.ordinal-position').text( $index + ordinalSuffix( $index ) );
        }

      });

      // handle dragged item separatelly
      seq = ui.item.parent().find( 'li.sort-placeholder').index() + correction;
      ui.item.find( '.ordinal-position' ).text( seq + ordinalSuffix( seq ) );
} );

// this function adds the correct ordinal suffix to the provide number
function ordinalSuffix( number )
{
  var suffix = '';

  if ( number / 10 % 10 === 1 )
  {
    suffix = "th";
  }
  else if ( number > 0 )
  {

    switch( number % 10 )
    {
      case 1:
        suffix = "st";
        break;
      case 2:
        suffix = "nd";
        break;
      case 3:
        suffix = "rd";
        break;
      default:
        suffix = "th";
        break;
    }
  }
  return suffix;
}

Your markup can look like this:

<ul class="sortable ">
<li >        
    <div>
        <span class="ordinal-position">1st</span>
         A header
    </div>
    <div>
        <span class="icon-button handle"><i class="fa fa-arrows"></i></span>
    </div>
    <div class="bpdy" >
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
    </div>
</li>
 <li >        
    <div>
        <span class="ordinal-position">2nd</span>
         A header
    </div>
    <div>
        <span class="icon-button handle"><i class="fa fa-arrows"></i></span>
    </div>
    <div class="bpdy" >
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
    </div>
</li>
etc....
</ul>

You will need to put the characters needs to be removed inside the square brackets during the time of replacement. The example code will be as following:

String s = "$116.42".replaceAll("[$]", "");

In Swift 3 here's how you do it to the UIImage itself:

let size = CGSize(width: image.size.width, height: image.size.height)
UIGraphicsBeginImageContext(size)
let rect = CGRect(x: 0, y: 0, width: size.width, height: size.height)
image?.draw(in: rect, blendMode: .normal, alpha: 1.0)
let context = UIGraphicsGetCurrentContext()
context?.setStrokeColor(red: 0, green: 0, blue: 0, alpha: 1)
context?.stroke(rect)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

self.imageView.image = newImage

Add xmlns context with http as shown below

xmlns:context="http://www.springframework.org/schema/context"

In python, it's called slicing. Here is an example of python's slice notation:

>>> list1 = ['a','b','c','d','e','f','g','h', 'i', 'j', 'k', 'l']
>>> print list1[:5]
['a', 'b', 'c', 'd', 'e']
>>> print list1[-7:]
['f', 'g', 'h', 'i', 'j', 'k', 'l']

Note how you can slice either positively or negatively. When you use a negative number, it means we slice from right to left.

Suppose you have data in A1:A10 and B1:B10 and you want to highlight which values in A1:A10 do not appear in B1:B10.

Try as follows:

1. Format > Conditional Formating...
2. Select 'Formula Is' from drop down menu

3. Enter the following formula:

   =ISERROR(MATCH(A1,$B$1:$B$10,0))

4. Now select the format you want to highlight the values in col A that do not appear in col B

This will highlight any value in Col A that does not appear in Col B.

I know that there have already been some good answers, but I came across this question with a Google Search and I wish someone would have pointed out this online checking tool...

http://www.tormus.com/tools/div_checker

You just throw in a URL and it will show you the entire map of the page. Very useful for a quick debug like I needed.

Your problem is basically that you never specified the right path to the file.

Try instead, from your main script:

from folder.file import Klasa

Or, with from folder import file:

from folder import file
k = file.Klasa()

Or again:

import folder.file as myModule
k = myModule.Klasa()

use isinstance(v, type_name) or type(v) is type_name or type(v) == type_name,

where type_name can be one of the following:

• None
• bool
• int
• float
• complex
• str
• list
• tuple
• set
• dict

and, of course,

• custom types (classes)

For me, I'm using Windows 10, @andrew-marshall's instructions worked (Thanks!) except that git.exe was within a cmd directory within PortableGit..., not bin, so I had to put \cmd on the end of the path I added to PATH. Thought I would post this here in case anyone else hits the same issue. You can tell it works once git in a new Command Prompt window returns command usage info and not an error.

It's not relative to performance...

You set async to false, when you need that ajax request to be completed before the browser passes to other codes:

<script>
    // ...
    $.ajax(... async: false ...); // Hey browser! first complete this request, 
                                  // then go for other codes

    $.ajax(...); // Executed after the completion of the previous async:false request.
</script>

Using iterators...no, I don't think so. You'll have to hack together something like this:

    Collection< String > collection = new ArrayList< String >( Arrays.asList( "foo", "bar", "baz" ) );
    int i = 0;
    while ( i < collection.size() ) {

        String curItem = collection.toArray( new String[ collection.size() ] )[ i ];
        if ( curItem.equals( "foo" ) ) {
            collection.add( "added-item-1" );
        }
        if ( curItem.equals( "added-item-1" ) ) {
            collection.add( "added-item-2" );
        }

        i++;
    }

    System.out.println( collection );

Which yeilds:
[foo, bar, baz, added-item-1, added-item-2]

In case you have smaller data set, a way to achieve it by GUI is:

1. Open a query window
2. SELECT * FROM [table_name]
3. Select Import from the menu bar
4. Press Apply on the bottom right below the Result Grid

Reference: http://www.youtube.com/watch?v=tnhJa_zYNVY

1. Close Android Studio.

2. Rename the folder of the root of the project. For example, change "MyApplication" to "Myblablabla".

3. Delete the '.idea' folder.

4. Open Android Studio, and import the updated project.

I had a requirement where multiple instances of a console application needed to get an unique integer ID. It is used to identify the instance and assigned at startup. Because the .exe is started by hands, I settled on a solution using the ticks of the start time.

My reasoning was that it would be nearly impossible for the user to start two .exe in the same millisecond. This behavior is deterministic: if you have a collision, you know that the problem was that two instances were started at the same time. Methods depending on hashcode, GUID or random numbers might fail in unpredictable ways.

I set the date to 0001-01-01, add the current time and divide the ticks by 10000 (because I don't set the microseconds) to get a number that is small enough to fit into an integer.

 var now = DateTime.Now;
 var zeroDate = DateTime.MinValue.AddHours(now.Hour).AddMinutes(now.Minute).AddSeconds(now.Second).AddMilliseconds(now.Millisecond);
 int uniqueId = (int)(zeroDate.Ticks / 10000);

EDIT: There are some caveats. To make collisions unlikely, make sure that:

• The instances are started manually (more than one millisecond apart)
• The ID is generated once per instance, at startup
• The ID must only be unique in regard to other instances that are currently running
• Only a small number of IDs will ever be needed

This works for Bootstrap 3 without JS code and is responsive.

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

Maybe it will be to complex for this question but it surely do the job for you. I have created two classes to handle not only array insertion but also querying the database, updating and deleting files. "MySqliConnection" class is used to create only one instance of db connection (to prevent duplication of new objects).

    <?php
    /**
     *
     * MySQLi database connection: only one connection is allowed
     */
    class MySqliConnection{
        public static $_instance;
        public $_connection;

        public function __construct($host, $user, $password, $database){

The second "TableManager" class is little bit more complex. It also make use of the MySqliConnection class which I posted above. So you would have to include both of them in your project.

You can put this in your .h file for your class and define it as property, in XCode 7:

@property int  (*stuffILike) [10];

This is a good exercise for yourself to work on :)

You should break your library into three parts

• Loading the CSV file
• Representing the file in memory so that you can modify it and read it
• Saving the CSV file back to disk

So you are looking at writing a CSVDocument class that contains:

• Load(const char* file);
• Save(const char* file);
• GetBody

So that you may use your library like this:

CSVDocument doc;
doc.Load("file.csv");
CSVDocumentBody* body = doc.GetBody();

CSVDocumentRow* header = body->GetRow(0);
for (int i = 0; i < header->GetFieldCount(); i++)
{
    CSVDocumentField* col = header->GetField(i);
    cout << col->GetText() << "\t";
}

for (int i = 1; i < body->GetRowCount(); i++) // i = 1 so we skip the header
{
    CSVDocumentRow* row = body->GetRow(i);
    for (int p = 0; p < row->GetFieldCount(); p++)
    {
        cout << row->GetField(p)->GetText() << "\t";
    }
    cout << "\n";
}

body->GetRecord(10)->SetText("hello world");

CSVDocumentRow* lastRow = body->AddRow();
lastRow->AddField()->SetText("Hey there");
lastRow->AddField()->SetText("Hey there column 2");

doc->Save("file.csv");

Which gives us the following interfaces:

class CSVDocument
{
public:
    void Load(const char* file);
    void Save(const char* file);

    CSVDocumentBody* GetBody();
};

class CSVDocumentBody
{
public:
    int GetRowCount();
    CSVDocumentRow* GetRow(int index);
    CSVDocumentRow* AddRow();
};

class CSVDocumentRow
{
public:
    int GetFieldCount();
    CSVDocumentField* GetField(int index);
    CSVDocumentField* AddField(int index);
};

class CSVDocumentField
{
public:
    const char* GetText();
    void GetText(const char* text);
};

Now you just have to fill in the blanks from here :)

Believe me when I say this - investing your time into learning how to make libraries, especially those dealing with the loading, manipulation and saving of data, will not only remove your dependence on the existence of such libraries but will also make you an all-around better programmer.

:)

EDIT

I don't know how much you already know about string manipulation and parsing; so if you get stuck I would be happy to help.

In mysql definitions (manual) there is no such thing. But if you have a really big number of columns col1, ..., col100, the following can be useful:

DROP TABLE IF EXISTS temp_tb;
CREATE TEMPORARY TABLE ENGINE=MEMORY temp_tb SELECT * FROM orig_tb;
ALTER TABLE temp_tb DROP col_x;
   #// ALTER TABLE temp_tb DROP col_a, ... , DROP col_z; #// for a few columns to drop
SELECT * FROM temp_tb;

base64.b16encode and base64.b16decode convert bytes to and from hex and work across all Python versions. The codecs approach also works, but is less straightforward in Python 3.

Sometimes you can refactor your @Component to use constructor or setter based injection to setup your testcase (you can and still rely on @Autowired). Now, you can create your test entirely without a mocking framework by implementing test stubs instead (e.g. Martin Fowler's MailServiceStub):

@Component
public class MyLauncher {

    private MyService myService;

    @Autowired
    MyLauncher(MyService myService) {
        this.myService = myService;
    }

    // other methods
}

public class MyServiceStub implements MyService {
    // ...
}

public class MyLauncherTest
    private MyLauncher myLauncher;
    private MyServiceStub myServiceStub;

    @Before
    public void setUp() {
        myServiceStub = new MyServiceStub();
        myLauncher = new MyLauncher(myServiceStub);
    }

    @Test
    public void someTest() {

    }
}

This technique especially useful if the test and the class under test is located in the same package because then you can use the default, package-private access modifier to prevent other classes from accessing it. Note that you can still have your production code in src/main/java but your tests in src/main/test directories.

If you like Mockito then you will appreciate the MockitoJUnitRunner. It allows you to do "magic" things like @Manuel showed you:

@RunWith(MockitoJUnitRunner.class)
public class MyLauncherTest
    @InjectMocks
    private MyLauncher myLauncher; // no need to call the constructor

    @Mock
    private MyService myService;

    @Test
    public void someTest() {

    }
}

Alternatively, you can use the default JUnit runner and call the MockitoAnnotations.initMocks() in a setUp() method to let Mockito initialize the annotated values. You can find more information in the javadoc of @InjectMocks and in a blog post that I have written.

XMLSpy does that for you, although that's not free...

I believe that Liquid Xml Studio does it for you and is free, but I have not personally used it to create test data.

This would be better as a comment, sorry I do not have commenting permissions.

@mar10 comment was the missing piece I needed to do this.

Note that '/path/to/old/mercurial_repo' must be a path on the file system (not a URL), so you have to clone the original repository before. – mar10 Dec 27 '13 at 16:30

This comment was in regards to the answer that solved this for me, https://stackoverflow.com/a/10710294/2148757 which is the same answer as the one marked correct here, https://stackoverflow.com/a/16037861/2148757

This moved our hg project to git with the commit history intact.

<audio src="/music/good_enough.mp3">
<p>If you are reading this, it is because your browser does not support the audio element.     </p>
</audio>

and if you want the controls

<audio src="/music/good_enough.mp3" controls>
<p>If you are reading this, it is because your browser does not support the audio element.</p>
</audio>

and also using embed

<embed src="/music/good_enough.mp3" width="180" height="90" loop="false" autostart="false" hidden="true" />

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

Those are not files (they don't exist on disk) - they are just names under which some HTTP handlers are registered. Take a look at the web.config in .NET Framework's directory (e.g. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config):

<configuration>
  <system.web>
    <httpHandlers>
      <add path="eurl.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
      <add path="trace.axd" verb="*" type="System.Web.Handlers.TraceHandler" validate="True" />
      <add path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader" validate="True" />
      <add verb="*" path="*_AppService.axd" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False" />
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="False"/>
      <add path="*.axd" verb="*" type="System.Web.HttpNotFoundHandler" validate="True" />
    </httpHandlers>
  </system.web>
<configuration>

You can register your own handlers with a whatever.axd name in your application's web.config. While you can bind your handlers to whatever names you like, .axd has the upside of working on IIS6 out of the box by default (IIS6 passes requests for *.axd to the ASP.NET runtime by default). Using an arbitrary path for the handler, like Document.pdf (or really anything except ASP.NET-specific extensions), requires more configuration work. In IIS7 in integrated pipeline mode this is no longer a problem, as all requests are processed by the ASP.NET stack.

You can do navigation between view controllers using code with the help of storyboard and storyboardId of the view controller. This code is for Swift 3:

let signUpVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SignUp")
self.navigationController?.pushViewController(signUpVC, animated: true)

Kevlar is correct.

An alternative to a custom DLL is Lua Alien

If you're using jQuery UI too, you can do like this:

var e = jQuery.Event("keypress");
e.keyCode = $.ui.keyCode.ENTER;
$("input").trigger(e);

var d = new Date();

// calling the function
formatDate(d,4);


function formatDate(dateObj,format)
{
    var monthNames = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ];
    var curr_date = dateObj.getDate();
    var curr_month = dateObj.getMonth();
    curr_month = curr_month + 1;
    var curr_year = dateObj.getFullYear();
    var curr_min = dateObj.getMinutes();
    var curr_hr= dateObj.getHours();
    var curr_sc= dateObj.getSeconds();
    if(curr_month.toString().length == 1)
    curr_month = '0' + curr_month;      
    if(curr_date.toString().length == 1)
    curr_date = '0' + curr_date;
    if(curr_hr.toString().length == 1)
    curr_hr = '0' + curr_hr;
    if(curr_min.toString().length == 1)
    curr_min = '0' + curr_min;

    if(format ==1)//dd-mm-yyyy
    {
        return curr_date + "-"+curr_month+ "-"+curr_year;       
    }
    else if(format ==2)//yyyy-mm-dd
    {
        return curr_year + "-"+curr_month+ "-"+curr_date;       
    }
    else if(format ==3)//dd/mm/yyyy
    {
        return curr_date + "/"+curr_month+ "/"+curr_year;       
    }
    else if(format ==4)// MM/dd/yyyy HH:mm:ss
    {
        return curr_month+"/"+curr_date +"/"+curr_year+ " "+curr_hr+":"+curr_min+":"+curr_sc;       
    }
}

You don't need ng-checked when you use ng-model. If you're performing CRUD on your HTML Form, just create a model for CREATE mode that is consistent with your EDIT mode during the data-binding:

CREATE Mode: Model with default values only

$scope.dataModel = {
   isItemSelected: true,
   isApproved: true,
   somethingElse: "Your default value"
}

EDIT Mode: Model from database

$scope.dataModel = getFromDatabaseWithSameStructure()

Then whether EDIT or CREATE mode, you can consistently make use of your ng-model to sync with your database.

Just add this to your Action file in some div or td, so that it comes with incoming XML object

    <script type="text/javascript">
    $("#formname").resetForm();
    </script>

Where "formname" is the id of form you want to edit

Tomcat can work in 2 modes:

• BIO – blocking I/O (one thread per connection)
• NIO – non-blocking I/O (many more connections than threads)

Tomcat 7 is BIO by default, although consensus seems to be "don't use Bio because Nio is better in every way". You set this using the protocol parameter in the server.xml file.

• BIO will be HTTP/1.1 or org.apache.coyote.http11.Http11Protocol
• NIO will be org.apache.coyote.http11.Http11NioProtocol

If you're using BIO then I believe they should be more or less the same.

If you're using NIO then actually "maxConnections=1000" and "maxThreads=10" might even be reasonable. The defaults are maxConnections=10,000 and maxThreads=200. With NIO, each thread can serve any number of connections, switching back and forth but retaining the connection so you don't need to do all the usual handshaking which is especially time-consuming with HTTPS but even an issue with HTTP. You can adjust the "keepAlive" parameter to keep connections around for longer and this should speed everything up.

If you want to ensure they all get called, use super at all levels.

Better variant to generate SQL script by SQL request. It will not ruin defaults/nulls.

SELECT concat
    (
        'ALTER TABLE ', 
            t1.TABLE_SCHEMA, 
            '.',

            ' MODIFY ', 
            t1.column_name,

I worked a little with RecyclerView and still prefer ListView.

1. Sure, both of them use ViewHolders, so this is not an advantage.

2. A RecyclerView is more difficult in coding.

3. A RecyclerView doesn't contain a header and footer, so it's a minus.

4. A ListView doesn't require to make a ViewHolder. In cases where you want to have a list with sections or subheaders it would be a good idea to make independent items (without a ViewHolder), it's easier and doesn't require separate classes.

As a careful programmer will often throw an exception for a special occurrence, it worth mentioning some general purpose exceptions like IllegalArgumentException and IllegalStateException and UnsupportedOperationException. IllegalArgumentException is my favorite:

throw new IllegalArgumentException("Word contains blank: " + word);

AdventureWorksDataContext db = new AdventureWorksDataContext();
db.Log = Console.Out;

// Get hte first customer record
Customer c = from cust in db.Customers select cust where id = 5;
Console.WriteLine(c.CustomerType);
c.CustomerType = 'I';
db.SubmitChanges(); // Save the changes away

The :: is called scope resolution operator. Can be used like this:

:: identifier
class-name :: identifier
namespace :: identifier

You can read about it here

i faced this problem and solved it by using following codes. I was beginning fragment transaction by using childfragment manager.

layout:

                  <fragment
                    class="com.google.android.youtube.player.YouTubePlayerSupportFragment"
                    android:id="@+id/youtube_fragment"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

this is how i began fragment transaction:

   youTubePlayerFragment = (YouTubePlayerSupportFragment) getChildFragmentManager().findFragmentById(R.id.youtube_fragment);

the following codes explains how i removed the fragment which added by using childfragmentmanger.

@Override
    public void onDestroyView() {
        super.onDestroyView();

        youTubePlayerFragment = (YouTubePlayerSupportFragment) getChildFragmentManager().findFragmentById(R.id.youtube_fragment);

        if (youTubePlayerFragment != null)
        {
            getChildFragmentManager().beginTransaction().remove(youTubePlayerFragment).commitAllowingStateLoss();
        }

        youTubePlayer = null;
    }

for the plugins that doesn't use fn namespace (for example pnotify), this works:

if($.pluginname) {
    alert("plugin loaded");
} else {
    alert("plugin not loaded");
}

This doesn't work:

if($.fn.pluginname)

As suggested by Adam Miller in the comments, I'll add another solution.

The MailMessage(String from, String to) constructor accepts a comma separated list of addresses. So if you happen to have already a comma (',') separated list, the usage is as simple as:

MailMessage Msg = new MailMessage(fromMail, addresses);

In this particular case, we can replace the ';' for ',' and still make use of the constructor.

MailMessage Msg = new MailMessage(fromMail, addresses.replace(";", ","));

Whether you prefer this or the accepted answer it's up to you. Arguably the loop makes the intent clearer, but this is shorter and not obscure. But should you already have a comma separated list, I think this is the way to go.

This works:

package main

import (
    "fmt"
    "os"
    "os/signal"
    "syscall"
    "time" // or "runtime"
)

func cleanup() {
    fmt.Println("cleanup")
}

func main() {
    c := make(chan os.Signal)
    signal.Notify(c, os.Interrupt, syscall.SIGTERM)
    go func() {
        <-c
        cleanup()
        os.Exit(1)
    }()

    for {
        fmt.Println("sleeping...")
        time.Sleep(10 * time.Second) // or runtime.Gosched() or similar per @misterbee
    }
}

In Html5, you can now use

<form>
<input type="number" min="1" max="100">
</form>

Downloading jstl-1.2.jar instead of jstl.jar solves the problem

You are all not fully correct. You cannot write:

formObj[input.name] = input.value;

Because this way if you have multiselect list - its values will be overwritten with the last one, since it's transmitted as: "param1" : "value1", "param1" : "value2".

So, correct approach is:

if (formData[input.name] === undefined) {
    formData[input.name] = input.value;
}
else {
    var inputFieldArray = $.merge([], $.isArray(formData[input.name]) ? formData[input.name] : [formData[input.name]]);
    $.merge(inputFieldArray, [input.value]);
    formData[input.name] = $.merge([], inputFieldArray);
}

Canonical Data in RDBMS, Graph Data;
Think as "Normalization" or "Normal form" of a data in a RDBMS. Same data exists in different tables, represented with a unique identifier and mapped it in different tables.
or
Think a single form of a data in Graph Database that represented in many triples.

Major benefit of it is to make Dml (Data manipulation) more efficient since you can upsert (insert/update) only one value instead of many.

The console is no extra window anymore but it is under the texteditor area. You can set the preferences to always show this area. Go to "General" "Run Start" and activate "Show Debugger". Under "Run completes" the Debugger is set to hide again. You should deactivate that option. Now the console will remain visible.

EDIT

In the latest GM Release you can show and hide the console via a button in the toolbar. Very easy.

Try this one:

System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

For document references, not collections, you need:

// when you know the 'id'

this.afs.doc(`items/${id}`)
  .snapshotChanges().pipe(
    map((doc: any) => {
      const data = doc.payload.data();
      const id = doc.payload.id;
      return { id, ...data };
    });

as .valueChanges({ idField: 'id'}); will not work here. I assume it was not implemented since generally you search for a document by the id...

**403 Forbidden **

You don't have permission to access /Folder-Name/ on this server**

The solution for this problem is:

1.go to etc/apache2/apache2.conf

2.find the below code and change AllowOverride all to AllowOverride none

 <Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride all      Change this to--->  AllowOverride none
    Require all granted
 </Directory>

It will work fine on your Ubuntu server

As the title suggests that we want to adjust the size of the labels and not the tick marks I figured that I actually might add something to the question, you need to use the mtext() if you want to specify one of the label sizes, or you can just use par(cex.lab=2) as a simple alternative. Here's a more advanced mtext() example:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data=foo,
     yaxt="n", ylab="", 
     xlab="Regular boring x", 
     pch=16,
     col="darkblue")
axis(2,cex.axis=1.2)
mtext("Awesome Y variable", side=2, line=2.2, cex=2)

You may need to adjust the line= option to get the optimal positioning of the text but apart from that it's really easy to use.

The best practice for this, in my opinion is:

TimeUnit.DAYS.toMillis(1);     // 1 day to milliseconds.
TimeUnit.MINUTES.toMillis(23); // 23 minutes to milliseconds.
TimeUnit.HOURS.toMillis(4);    // 4 hours to milliseconds.
TimeUnit.SECONDS.toMillis(96); // 96 seconds to milliseconds.

For a quick and cheap way to host an angular app, I have been using the Firbase hosting. It's free on the first tier and very easy to deploy new versions using the Firebase CLI. This article here explains the necessary steps to deploy your production angular 2 app to Firebase: https://medium.com/codingthesmartway-com-blog/hosting-angular-2-applications-on-firebase-f194688c978d

In short, you run ng build --prod which creates a dist folder in the package and that's the folder that gets deployed to Firebase Hosting.

Swift 4 extension using explicit constraints:

import UIKit.UIView

extension UIView {
    public func addSubview(_ subview: UIView, stretchToFit: Bool = false) {
        addSubview(subview)
        if stretchToFit {
            subview.translatesAutoresizingMaskIntoConstraints = false
            leftAnchor.constraint(equalTo: subview.leftAnchor).isActive = true
            rightAnchor.constraint(equalTo: subview.rightAnchor).isActive = true
            topAnchor.constraint(equalTo: subview.topAnchor).isActive = true
            bottomAnchor.constraint(equalTo: subview.bottomAnchor).isActive = true
        }
    }
}

Usage:

parentView.addSubview(childView) // won't resize (default behavior unchanged)
parentView.addSubview(childView, stretchToFit: false) // won't resize
parentView.addSubview(childView, stretchToFit: true) // will resize

I solved this question this way.

<a class="btn btn-primary" target="_blank" ng-href="{{url}}" ng-mousedown="openTab()">newTab</a>

$scope.openTab = function() {
    $scope.url = 'www.google.com';
}

Addendum:

The important concept is that you are evaluating an expression in your Razor code. The best way to do this (if, for example, you are in a foreach loop) is using a generic method.

The syntax for calling a generic method in Razor is:

@(expression)

In this case, the expression is:

User.Identity.IsAuthenticated ? "auth" : "anon"

Therefore, the solution is:

@(User.Identity.IsAuthenticated ? "auth" : "anon")

This code can be used anywhere in Razor, not just for an html attribute.

See @Kyralessa 's comment for C# Razor Syntax Quick Reference (Phil Haack's blog).

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

I had the same problem and the only thing that works for my was to uninstall entity framework package from each project using Uninstall-Package. And then intall it again in the whole solution. It will ask you to choose in which project you want to install it, you shall select all.

you can try to this , then you get a bitmap of selected image and then you can easily find it's native path from Device Default Gallery.

Bitmap roughBitmap= null;
    try {
    // Works with content://, file://, or android.resource:// URIs
    InputStream inputStream =
    getContentResolver().openInputStream(uri);
    roughBitmap= BitmapFactory.decodeStream(inputStream);

    // calc exact destination size
    Matrix m = new Matrix();
    RectF inRect = new RectF(0, 0, roughBitmap.Width, roughBitmap.Height);
    RectF outRect = new RectF(0, 0, dstWidth, dstHeight);
    m.SetRectToRect(inRect, outRect, Matrix.ScaleToFit.Center);
    float[] values = new float[9];
    m.GetValues(values);


    // resize bitmap if needed
    Bitmap resizedBitmap = Bitmap.CreateScaledBitmap(roughBitmap, (int) (roughBitmap.Width * values[0]), (int) (roughBitmap.Height * values[4]), true);

    string name = "IMG_" + new Java.Text.SimpleDateFormat("yyyyMMdd_HHmmss").Format(new Java.Util.Date()) + ".png";
    var sdCardPath= Environment.GetExternalStoragePublicDirectory("DCIM").AbsolutePath;
    Java.IO.File file = new Java.IO.File(sdCardPath);
    if (!file.Exists())
    {
        file.Mkdir();
    }
    var filePath = System.IO.Path.Combine(sdCardPath, name);
    } catch (FileNotFoundException e) {
    // Inform the user that things have gone horribly wrong
    }

Hai sridhar, I found an answer for your prob

ClientScript.RegisterClientScriptBlock(GetType(), "sas", "<script> alert('Inserted successfully');</script>", true);

change false to true

or try this

ScriptManager.RegisterClientScriptBlock(ursavebuttonID, typeof(LinkButton or button), "sas", "<script> alert('Inserted successfully');</script>", true);

I tried to use the suggestions above and in the process improved upon the solutions in this thread.

The base class is based on Josh Smith's article here From http://joshsmithonwpf.wordpress.com/2007/08/29/a-base-class-which-implements-inotifypropertychanged/

I did rename the class to be called ObservableObject and also took advantage of a c# 5 feature using the CallerMemberName attribute

Here is the part that you guys are going to like some more. I built a Powershell script to generate for all the tables in a SQL database. It is based on a Powershell guru named Chad Miller's Invoke-SQLCmd2 cmdlet which can be downloaded from here: http://gallery.technet.microsoft.com/ScriptCenter/7985b7ef-ed89-4dfd-b02a-433cc4e30894/

Once you have that cmdlet, the Powershell script to generate for all tables becomes simple (do substitute the variables with your specific values).

. C:\MyScripts\Invoke-Sqlcmd2.ps1

$serverInstance = "MySQLInstance"
$databaseName = "MyDb"
$generatorSQLFile = "C:\MyScripts\ModelGen.sql" 
$tableListSQL = "SELECT name FROM $databaseName.sys.tables"
$outputFolder = "C:\MyScripts\Output\"
$namespace = "MyCompany.Business"

$placeHolderSchema = "&Schema"
$placeHolderTableName = "&TableName"
$placeHolderNamespace = "&Namespace"

#Get the list of tables in the database to generate c# models for
$tables = Invoke-Sqlcmd2 -ServerInstance $serverInstance -Database $databaseName -Query $tableListSQL -As DataRow -Verbose

foreach ($table in $tables)
{
    $table1 = $table[0]
    $outputFile = "$outputFolder\$table1.cs"


    #Replace variables with values (returns an array that we convert to a string to use as query)
    $generatorSQLFileWSubstitutions = (Get-Content $generatorSQLFile).
                                            Replace($placeHolderSchema,"dbo").
                                            Replace($placeHolderTableName, $table1).
                                            Replace($placeHolderNamespace, $namespace) | Out-String

    "Ouputing for $table1 to $outputFile"

    #The command generates .cs file content for model using "PRINT" statements which then gets written to verbose output (stream 4)
    # ...capture the verbose output and redirect to a file
    (Invoke-Sqlcmd2 -ServerInstance $serverInstance -Database $databaseName -Query $generatorSQLFileWSubstitutions -Verbose) 4> $outputFile

}

My problem was to access the logged in User as an object in the cshtml file. Considering you wanted the user in ViewData, this approach might be helpful:

In the cshtml file

@using Microsoft.AspNetCore.Identity
@inject UserManager<ApplicationUser> UserManager

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>
    @UserManager.FindByNameAsync(UserManager.GetUserName(User)).Result.Email
    </title>
  </head>
  <body>

  </body>
</html>

If you're interested in how an open source project does stuff like this, you can check out the Terracotta class (Os.java) that handles this junk here:

• http://svn.terracotta.org/svn/tc/dso/trunk/code/base/common/src/com/tc/util/runtime/
• http://svn.terracotta.org/svn/tc/dso/tags/2.6.4/code/base/common/src/com/tc/util/runtime/

And you can see a similar class to handle JVM versions (Vm.java and VmVersion.java) here:

• http://svn.terracotta.org/svn/tc/dso/trunk/common/src/main/java/com/tc/util/runtime/

you may also like this

var Grp = Model.GroupBy(item => item.Order.Customer)
      .Select(group => new 
        { 
             Customer = Model.First().Customer, 
             CustomerId= group.Key,  
             Orders= group.ToList() 
       })
      .ToList();

I use

patch -p1 --merge < patchfile

This way, conflicts may be resolved as usual.

I was having the same problem using the python email functions. Below is the code I was trying to retrieve email subject into a variable. This works fine for most emails and the variable populates. If you receive an email from Yahoo or the like and the sender did no fill out the subject line Yahoo does not create a subject line in the email and you get a NoneType returned from the function. Martineau provided a correct answer as well as Soviut. IMO Soviut's answer is more concise from a programming stand point; not necessarily from a Python one. Here is some code to show the technique:

import sys, email, email.Utils 

afile = open(sys.argv[1], 'r')    
m = email.message_from_file(afile)    
subject = m["subject"]

# Soviut's Concise test for unset variable.

if subject is None:    
     subject = "[NO SUBJECT]"

# Alternative way to test for No Subject created in email (Thanks for NoneThing Yahoo!)

try:    
    if len(subject) == 0:    
        subject = "[NO SUBJECT]"

except TypeError:    
    subject = "[NO SUBJECT]"

print subject

afile.close()

Powershell 2.0:

(see detailed explanation here)

$text = Get-Content $filePath | Out-String

The IO.File.ReadAllText didn't work for me with a relative path, it looks for the file in %USERPROFILE%\$filePath instead of the current directory (when running from Powershell ISE at least):

$text = [IO.File]::ReadAllText($filePath)

Powershell 3+:

$text = Get-Content $filePath -Raw

SQL Supports following types of affinities:

• TEXT
• NUMERIC
• INTEGER
• REAL
• BLOB

If the declared type for a column contains any of these "REAL", "FLOAT", or "DOUBLE" then the column has 'REAL' affinity.

if the file containing that link tag is in the root dir of the project, then the correct path would be "css/styles.css"

The following CSS declaration works for me:

.td-limit {
    max-width: 70px;
    text-overflow: ellipsis;
    white-space: nowrap;
    overflow: hidden;
}

This how you can do it.

const date = new Date();_x000D_
const time = date.toTimeString().split(' ')[0].split(':');_x000D_
console.log(time[0] + ':' + time[1])

Are you looking for something like this?

SELECT CASE WHEN LEFT(created_ts, 1) LIKE '[0-9]' 
            THEN CONVERT(VARCHAR(10), CONVERT(datetime, created_ts,   1), 101)
            ELSE CONVERT(VARCHAR(10), CONVERT(datetime, created_ts, 109), 101)
      END created_ts
  FROM table1

Output:

| CREATED_TS |
|------------|
| 02/20/2012 |
| 11/29/2012 |
| 02/20/2012 |
| 11/29/2012 |
| 02/20/2012 |
| 11/29/2012 |
| 11/16/2011 |
| 02/20/2012 |
| 11/29/2012 |

Here is SQLFiddle demo

If you want to add an interval before executing the cron the next time you can add a sleep

for i in {1..100}; do echo $i && curl "http://URL" >> /tmp/output.log && sleep 120; done

This one worked for me

var dataArray = Object.keys(dataObject).map(function(k){return dataObject[k]});

You can compare class tokens to each other, so you could use value.getClass() == Integer.class. However, the simpler and more canonical way is to use instanceof :

    if (value instanceof Integer) {
        System.out.println("This is an Integer");
    } else if(value instanceof String) {
        System.out.println("This is a String");
    } else if(value instanceof Float) {
        System.out.println("This is a Float");
    }

Notes:

• the only difference between the two is that comparing class tokens detects exact matches only, while instanceof C matches for subclasses of C too. However, in this case all the classes listed are final, so they have no subclasses. Thus instanceof is probably fine here.

• as JB Nizet stated, such checks are not OO design. You may be able to solve this problem in a more OO way, e.g.

  System.out.println("This is a(n) " + value.getClass().getSimpleName());
  

This means that you are doing a foreach on something that is not an array.

Check out all your foreach statements, and look if the thing before the as, to make sure it is actually an array. Use var_dump to dump it.

Then fix the one where it isn't an array.

How to reproduce this error:

<?php
$skipper = "abcd";
foreach ($skipper as $item){       //the warning happens on this line.
    print "ok";
}
?>

Make sure $skipper is an array.

Update:

As of Notepad++ v7.6, use Plugin Admin to install JSTool per this answer

As @yigit mentioned, you need to override onMeasure(). Both @user2302510 and @DenisNek have good answers but if you want to support ItemDecoration you can use this custom layout manager.

And other answers cannot scroll when there are more items than can be displayed on the screen though. This one is using default implemantation of onMeasure() when there are more items than screen size.

public class MyLinearLayoutManager extends LinearLayoutManager {

public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout)    {
    super(context, orientation, reverseLayout);
}

private int[] mMeasuredDimension = new int[2];

@Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                      int widthSpec, int heightSpec) {
    final int widthMode = View.MeasureSpec.getMode(widthSpec);
    final int heightMode = View.MeasureSpec.getMode(heightSpec);
    final int widthSize = View.MeasureSpec.getSize(widthSpec);
    final int heightSize = View.MeasureSpec.getSize(heightSpec);
    int width = 0;
    int height = 0;
    for (int i = 0; i < getItemCount(); i++) {
        measureScrapChild(recycler, i,
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                mMeasuredDimension);

        if (getOrientation() == HORIZONTAL) {
            width = width + mMeasuredDimension[0];
            if (i == 0) {
                height = mMeasuredDimension[1];
            }
        } else {
            height = height + mMeasuredDimension[1];
            if (i == 0) {
                width = mMeasuredDimension[0];
            }
        }
    }

    // If child view is more than screen size, there is no need to make it wrap content. We can use original onMeasure() so we can scroll view.
    if (height < heightSize && width < widthSize) {

        switch (widthMode) {
            case View.MeasureSpec.EXACTLY:
                width = widthSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        switch (heightMode) {
            case View.MeasureSpec.EXACTLY:
                height = heightSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    } else {
        super.onMeasure(recycler, state, widthSpec, heightSpec);
    }
}

private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                               int heightSpec, int[] measuredDimension) {

   View view = recycler.getViewForPosition(position);

   // For adding Item Decor Insets to view
   super.measureChildWithMargins(view, 0, 0);
    if (view != null) {
        RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
        int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                    getPaddingLeft() + getPaddingRight() + getDecoratedLeft(view) + getDecoratedRight(view), p.width);
            int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                    getPaddingTop() + getPaddingBottom() + getPaddingBottom() + getDecoratedBottom(view) , p.height);
            view.measure(childWidthSpec, childHeightSpec);

            // Get decorated measurements
            measuredDimension[0] = getDecoratedMeasuredWidth(view) + p.leftMargin + p.rightMargin;
            measuredDimension[1] = getDecoratedMeasuredHeight(view) + p.bottomMargin + p.topMargin;
            recycler.recycleView(view);
        }
    }
}

And if you want to use it with GridLayoutManager just extends it from GridLayoutManager and change

for (int i = 0; i < getItemCount(); i++)

to

for (int i = 0; i < getItemCount(); i = i + getSpanCount())

I know this is late, but the answer is simply removing "time" from the word, datetimepicker to change it to datepicker. You can format it with dateFormat.

      jQuery( "#datetimepicker4" ).datepicker({
        dateFormat: "MM dd, yy",
      });

Your __autoload function will receive the full class-name, including the namespace name.

This means, in your case, the __autoload function will receive 'Person\Barnes\David\Class1', and not only 'Class1'.

So, you have to modify your autoloading code, to deal with that kind of "more-complicated" name ; a solution often used is to organize your files using one level of directory per "level" of namespaces, and, when autoloading, replace '\' in the namespace name by DIRECTORY_SEPARATOR.

Instead of sudo, try

su - username command

In my experience, sudo is not always available on RHEL systems, but su is, because su is part of the coreutils package whereas sudo is in the sudo package.

Difference between split and partition is split returns the list without delimiter and will split where ever it gets delimiter in string i.e.

x = 'http://test.com/lalala-134-431'

a,b,c = x.split(-)
print(a)
"http://test.com/lalala"
print(b)
"134"
print(c)
"431"

and partition will divide the string with only first delimiter and will only return 3 values in list

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala"
print(b)
"-"
print(c)
"134-431"

so as you want last value you can use rpartition it works in same way but it will find delimiter from end of string

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala-134"
print(b)
"-"
print(c)
"431"

This works in Python 3.x and 2.x:

# Fix Python 2.x.
try: input = raw_input
except NameError: pass
print("Hi " + input("Say something: "))

The simplest way:

Arrays.sort(myArr, (a, b) -> a[0] - b[0]);

2019 update

As pointed out by others in related questions (see here, here, here, here, here, here, and here), you can now unstage a file with git restore --staged <file>.

To unstage all the files in your project, run the following from the root of the repository (the command is recursive):

git restore --staged .

If you only want to unstage the files in a directory, navigate to it before running the above or run:

git restore --staged <directory-path>

Notes

• git restore was introduced in July 2019 and released in version 2.23.
  With the --staged flag, it restores the content of the working tree from HEAD (so it does the opposite of git add and does not delete any change).

• This is a new command, but the behaviour of the old commands remains unchanged. So the older answers with git reset or git reset HEAD are still perfectly valid.

• When running git status with staged uncommitted file(s), this is now what Git suggests to use to unstage file(s) (instead of git reset HEAD <file> as it used to prior to v2.23).

FWIW, the real problem was that I had included a semicolon at the end of my \set command:

\set owner_password 'thepassword';

The semicolon was interpreted as an actual character in the variable:

\echo :owner_password thepassword;

So when I tried to use it:

CREATE ROLE myrole LOGIN UNENCRYPTED PASSWORD :owner_password NOINHERIT CREATEDB CREATEROLE VALID UNTIL 'infinity';

...I got this:

CREATE ROLE myrole LOGIN UNENCRYPTED PASSWORD thepassword; NOINHERIT CREATEDB CREATEROLE VALID UNTIL 'infinity';

That not only failed to set the quotes around the literal, but split the command into 2 parts (the second of which was invalid as it started with "NOINHERIT").

The moral of this story: PostgreSQL "variables" are really macros used in text expansion, not true values. I'm sure that comes in handy, but it's tricky at first.

simply click

'Database'>tables>your table name>keys>copy the constraints like 'PK__TableName__30242045'

and run the below query is :

Query:alter Table 'TableName' drop constraint PK__TableName__30242045

Contrary to what pointy says, the blur() method does exist and is a part of the w3c standard. The following exaple will work in every modern browser (including IE):

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

            {
                var field = document.getElementById("field");
                var link = document.getElementById("link");
                var output = document.getElementById("output");

                field.onfocus = function() { output.innerHTML += "<br/>field.onfocus()"; };
                field.onblur = function() { output.innerHTML += "<br/>field.onblur()"; };
                link.onmouseover = function() { field.blur(); };
            };
        </script>
    </head>
    <body>
        <form name="MyForm">
            <input type="text" name="field" id="field" />
            <a href="javascript:void(0);" id="link">Blur field on hover</a>
            <div id="output"></div>
        </form>
    </body>
</html>

Note that I used link.onmouseover instead of link.onclick, because otherwise the click itself would have removed the focus.

Reference the checkbox by it's id and not with the # Assign the function to the onclick attribute rather than using the change attribute

var checkbox = $("save_" + fieldName);
checkbox.onclick = function(event) {
    var checkbox = event.target;

    if (checkbox.checked) {
        //Checkbox has been checked
    } else {
        //Checkbox has been unchecked
    }
};

Thanks for your answers, @mvp, @xero, I get what I want base on both of your answers.

2. Still could not download Homebrew
3. I installed Command Line Tool manually through link.

Just add a question mark ? to the optional field.

interface Employee{
   id: number;
   name: string;
   salary?: number;
}

SUM is used to sum the value in a column for multiple rows. You can just add your columns together:

select tblExportVertexCompliance.TotalDaysOnIncivek + tblExportVertexCompliance.IncivekDaysOtherSource AS [Total Days on Incivek]

gcc objectfiles -o program -Wl,-Bstatic -ls1 -ls2 -Wl,-Bdynamic -ld1 -ld2

you can also use: -static-libgcc -static-libstdc++ flags for gcc libraries

keep in mind that if libs1.so and libs1.a both exists, the linker will pick libs1.so if it's before -Wl,-Bstatic or after -Wl,-Bdynamic. Don't forget to pass -L/libs1-library-location/ before calling -ls1.

npm link pain:

-Module name gulp-task

-Project name project-x

You want to link gulp-task:

1: Go to the gulp-task directory then do npm link this will symlink the project to your global modules

2: Go to your project project-x then do npm install make sure to remove the current node_modules directory

Now you want to remove this madness and use the real gulp-task, we have two options:

Option 1: Unlink via npm:

1: Go to your project and do npm unlink gulp-task this will remove the linked installed module

2: Go to the gulp-task directory and do npm unlink to remove symlink. Notice we didn't use the name of the module

3: celebrate

What if this didn't work, verify by locating your global installed module. My are location ls -la /usr/local/lib/node_modules/ if you are using nvm it will be a different path

Option 2: Remove the symlink like a normal linux guru

1: locate your global dependencies cd /usr/local/lib/node_modules/

2: removing symlink is simply using the rm command

rm gulp-task make sure you don't have / at the end

rm gulp-task/ is wrong

rm gulp-task ??

• As the name suggested, var is variable without any data type.
• If you don't know which type of data will be returned by any method, such cases are good for using var.
• var is Implicit type which means system will define the data type itself. The compiler will infer its type based on the value to the right of the "=" operator.
• int/string etc. are the explicit types as it is defined by you explicitly.
• Var can only be defined in a method as a local variable
• Multiple vars cannot be declared and initialized in a single statement. For example, var i=1, j=2; is invalid.

int i = 100;// explicitly typed 
var j = 100; // implicitly typed

Since you are asking about .NET, you should change the parameter from Long to Integer. .NET's Integer is 32-bit. (Classic VB's integer was only 16-bit.)

Declare Sub Sleep Lib "kernel32.dll" (ByVal Milliseconds As Integer)

Really though, the managed method isn't difficult...

System.Threading.Thread.CurrentThread.Sleep(5000)

Be careful when you do this. In a forms application, you block the message pump and what not, making your program to appear to have hanged. Rarely is sleep a good idea.

bool is an alias for System.Boolean just as int is an alias for System.Int32. See a full list of aliases here: Built-In Types Table (C# Reference).

All you have to do is apply the format you want in the html helper call, ie.

@Html.TextBoxFor(m => m.RegistrationDate, "{0:dd/MM/yyyy}")

You don't need to provide the date format in the model class.

Use numpy.asscalar to convert a numpy array / matrix a scalar value:

>>> a=numpy.array([[[[42]]]])
>>> numpy.asscalar(a)
42

The output data type is the same type returned by the input’s item method.

It has built in error-checking if there is more than an single element:

>>> a=numpy.array([1, 2])
>>> numpy.asscalar(a)

gives:

ValueError: can only convert an array of size 1 to a Python scalar

Note: the object passed to asscalar must respond to item, so passing a list or tuple won't work.

If you were only interested in 'z', you could create a function-based index.

CREATE INDEX users_z_idx ON users (INSTR(last_name,'z'))

Then your query would use WHERE INSTR(last_name,'z') > 0.

With this approach you would have to create a separate index for each character you might want to search for. I suppose if this is something you do often, it might be worth creating one index for each letter.

Also, keep in mind that if your data has the names capitalized in the standard way (e.g., "Zaxxon"), then both your example and mine would not match names that begin with a Z. You can correct for this by including LOWER in the search expression: INSTR(LOWER(last_name),'z').

You may have problems if the Fullname doesn't contain a space. Assuming the whole of FullName goes to Surname if there is no space and FirstName becomes an empty string, then you can use this:

SELECT
  RTRIM(LEFT(FullName, CHARINDEX(' ', FullName))) AS FirstName,
  SUBSTRING(FullName, CHARINDEX(' ', FullName) + 1, 8000) AS LastName
FROM
  MyNameTable;

In code behind:

{
    yourDiv.Visible = false;
}

Use strpos():

if (strpos($string2, 'http') === 0) {
   // It starts with 'http'
}

Remember the three equals signs (===). It will not work properly if you only use two. This is because strpos() will return false if the needle cannot be found in the haystack.

According to section 2.2 of the manual, you can use the Escape key pressed twice in place of the CTRL key. This allowed me to use Nano's key combination for GO TO LINE when running Nano on a Jupyter/ JupyterHub and accessing through my browser. The normal key combination was getting 'swallowed' as the manual warns about can more often happen with the ALT key on some systems, and which can be replaced by one press of the ESCAPE key.
So for jump to line it was ESCAPE pressed twice, followed by shift key + dash key.

For windows, everybody said you should set environment variables for nodejs and npm modules, but do you know why? For some modules, they have command line tool, after installed the module, there'are [module].cmd file in C:\Program Files\nodejs, and it's used for launch in window command. So if you don't add the path containing the cmd file to environment variables %PATH% , you won't launch them successfully through command window.

You will need to convert your response to json before you can access response.body

From the docs

fetch(url)
  .then(response => response.json())
  .then(json => {
    console.log('parsed json', json) // access json.body here
  })

Strictly speaking, there's no difference, since you cannot do either :)

Function overriding could have been done with a PHP extension like APD, but it's deprecated and afaik last version was unusable.

Function overloading in PHP cannot be done due to dynamic typing, ie, in PHP you don't "define" variables to be a particular type. Example:

$a=1;
$a='1';
$a=true;
$a=doSomething();

Each variable is of a different type, yet you can know the type before execution (see the 4th one). As a comparison, other languages use:

int a=1;
String s="1";
bool a=true;
something a=doSomething();

In the last example, you must forcefully set the variable's type (as an example, I used data type "something").

Another "issue" why function overloading is not possible in PHP: PHP has a function called func_get_args(), which returns an array of current arguments, now consider the following code:

function hello($a){
  print_r(func_get_args());
}

function hello($a,$a){
  print_r(func_get_args());
}

hello('a');
hello('a','b');

Considering both functions accept any amount of arguments, which one should the compiler choose?

Finally, I'd like to point out why the above replies are partially wrong; function overloading/overriding is NOT equal to method overloading/overriding.

Where a method is like a function but specific to a class, in which case, PHP does allow overriding in classes, but again no overloading, due to language semantics.

To conclude, languages like Javascript allow overriding (but again, no overloading), however they may also show the difference between overriding a user function and a method:

/// Function Overriding ///

function a(){
   alert('a');
}
a=function(){
   alert('b');
}

a(); // shows popup with 'b'


/// Method Overriding ///

var a={
  "a":function(){
    alert('a');
  }
}
a.a=function(){
   alert('b');
}

a.a(); // shows popup with 'b'

The following line is looking for the exact NavigableString 'Python':

>>> soup.body.findAll(text='Python')
[]

Note that the following NavigableString is found:

>>> soup.body.findAll(text='Python Jobs') 
[u'Python Jobs']

Note this behaviour:

>>> import re
>>> soup.body.findAll(text=re.compile('^Python$'))
[]

So your regexp is looking for an occurrence of 'Python' not the exact match to the NavigableString 'Python'.

When building separate apks for different densities, drawable folders for other densities get stripped. This will make the icons appear blurry in devices that use launcher icons of higher density. Since, mipmap folders do not get stripped, it’s always best to use them for including the launcher icons.

Is there anything wrong with Nahuel Greco's solution aside from the compilation error?

If I change one line

// Compilation error
setsockopt(fd, SO_SNDTIMEO, &timeout, sizeof(timeout));

to

// Fixed?
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));

then it seems to work as advertised - socket() returns a timeout error.

Resulting code:

struct timeval timeout;
timeout.tv_sec  = 7;  // after 7 seconds connect() will timeout
timeout.tv_usec = 0;
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));
connect(...)

I'm not versed enough to know the tradeoffs are between a send timeout and a non-blocking socket, but I'm curious to learn.

It's deprecated but it still works so you could just use it. But if you want to be completly correct, just for the completeness of it... You'd do something like following:

int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    setBackgroundDrawable();
} else {
    setBackground();
}

For this to work you need to set buildTarget api 16 and min build to 7 or something similar.

You can use this command:

git branch --merged master | grep -v "\* master" | xargs -n 1 git branch -d

I faced the same problem,but after hours of efforts i find the solution.It can be without using any external plugin:)

applicantListToExport: function (query, callback) {
  this
   .find(query).select({'advtId': 0})
   .populate({
      path: 'influId',
      model: 'influencer',
      select: { '_id': 1,'user':1},
      populate: {
        path: 'userid',
        model: 'User'
      }
   })
 .populate('campaignId',{'campaignTitle':1})
 .exec(callback);
}

Another approach is to use android.intent.action.USER_PRESENT instead of android.intent.action.BOOT_COMPLETED to avoid slow downs during the boot process. But this is only true if the user has enabled the lock Screen - otherwise this intent is never broadcasted.

Best way to test api on postman tool.

My solution was to make all the parents 100% and set a specific percentage for each row:

html, body,div[class^="container"] ,.column {
    height: 100%;
}

.row0 {height: 10%;}
.row1 {height: 40%;}
.row2 {height: 50%;}

See: http://jsfiddle.net/thirtydot/cMNX2/8/

input {
    -webkit-box-shadow: 0 0 5px 2px #fff;
    -moz-box-shadow: 0 0 5px 2px #fff;
    box-shadow: 0 0 5px 2px #fff;
}

Add the separator to the li background and make sure the link doesn't expand to cover the separator, which means the separator won't be click-able.

CN refers to class name, so put in your LDAP query CN=Users. Should work.

Referencing the Rails documents we see that there are a few ways to link to images from css. Just go to section 2.3.2.

First, make sure your css file has the .scss extension if it's a sass file.

Next, you can use the ruby method, which is really ugly:

#logo { background: url(<%= asset_data_uri 'logo.png' %>) }

Or you can use the specific form that is nicer:

image-url("rails.png") returns url(/assets/rails.png)
image-path("rails.png") returns "/assets/rails.png"

Lastly, you can use the general form:

asset-url("rails.png") returns url(/assets/rails.png)
asset-path("rails.png") returns "/assets/rails.png"

this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

this worked for me in case of Class Extends Frame

Using spark sql query..just incase if it helps anyone!

import org.apache.spark.sql.SparkSession 
import org.apache.spark.SparkConf 
import org.apache.spark.sql.functions._ 
import org.apache.spark.SparkContext 
import java.util.stream.Collectors

val conf = new SparkConf().setMaster("local[2]").setAppName("test")
val spark = SparkSession.builder.config(conf).getOrCreate()
val df = spark.sparkContext.parallelize(Seq(1, 2, 3, 4, 5, 6, 7)).toDF()

df.createOrReplaceTempView("steps")
val sum = spark.sql("select  sum(steps) as stepsSum from steps").map(row => row.getAs("stepsSum").asInstanceOf[Long]).collect()(0)
println("steps sum = " + sum) //prints 28

Made a Grunt build with the Bootstrap 3.3.5 grid only:

~10KB minimized.

If you need some other parts from Bootstrap just include them in /src/less/bootstrap.less.

This answer is based on Yann's answer. It will set the aspect ratio for linear or log-log plots. I've used additional information from https://stackoverflow.com/a/16290035/2966723 to test if the axes are log-scale.

def forceAspect(ax,aspect=1):
    #aspect is width/height
    scale_str = ax.get_yaxis().get_scale()
    xmin,xmax = ax.get_xlim()
    ymin,ymax = ax.get_ylim()
    if scale_str=='linear':
        asp = abs((xmax-xmin)/(ymax-ymin))/aspect
    elif scale_str=='log':
        asp = abs((scipy.log(xmax)-scipy.log(xmin))/(scipy.log(ymax)-scipy.log(ymin)))/aspect
    ax.set_aspect(asp)

Obviously you can use any version of log you want, I've used scipy, but numpy or math should be fine.

From Python 2.5 onwards, you can use

from ..Modules import LDAPManager

The leading period takes you "up" a level in your heirarchy.

See the Python docs on intra-package references for imports.

I have a more useful version if you are interested. I lifted a bit of code from here a website where the link is no longer active. I modifyied it to allow for an array of tables into the stored procedure and it populates the drop, truncate, add statements before executing all of them. This gives you control to decide which tables need truncating.

This do not fully address the OP question but I though it may be useful to some coming here to search for nested structure regexp:

Parse parmeters from function string (with nested structures) in javascript

Match structures like:

• matches brackets, square brackets, parentheses, single and double quotes

Here you can see generated regexp in action

/**
 * get param content of function string.
 * only params string should be provided without parentheses
 * WORK even if some/all params are not set
 * @return [param1, param2, param3]
 */
exports.getParamsSAFE = (str, nbParams = 3) => {
    const nextParamReg = /^\s*((?:(?:['"([{](?:[^'"()[\]{}]*?|['"([{](?:[^'"()[\]{}]*?|['"([{][^'"()[\]{}]*?['")}\]])*?['")}\]])*?['")}\]])|[^,])*?)\s*(?:,|$)/;
    const params = [];
    while (str.length) { // this is to avoid a BIG performance issue in javascript regexp engine
        str = str.replace(nextParamReg, (full, p1) => {
            params.push(p1);
            return '';
        });
    }
    return params;
};

You can use inner divs to set the margin.

<div style="display: table-cell;">
   <div style="margin:5px;background-color: red;">1</div>
</div>
<div style="display: table-cell; ">
  <div style="margin:5px;background-color: green;">1</div>
</div>

JS Fiddle

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

You can use spread syntax as follows..

var alerts = { 
1: { app: 'helloworld', message: 'message' },
2: { app: 'helloagain', message: 'another message' }
 }

alerts = {...alerts, 3: {app: 'hey there', message: 'another message'} }

Created below method (for myself) to check if the given record id exists on Db table or not.

private function isModelRecordExist($model, $recordId)
{
    if (!$recordId) return false;

    $count = $model->where(['id' => $recordId])->count();

    return $count ? true : false;
}

// To Test
$recordId = 5;
$status = $this->isModelRecordExist( (new MyTestModel()), $recordId);

Home It helps!

From the Twitter FAQ:

Most integrations with the API will require you to identify your application to Twitter by way of an API key. On the Twitter platform, the term "API key" usually refers to what's called an OAuth consumer key. This string identifies your application when making requests to the API. In OAuth 1.0a, your "API keys" probably refer to the combination of this consumer key and the "consumer secret," a string that is used to securely "sign" your requests to Twitter.

If you really need it inline, for example because you are loading some user-defined colors dynamically, you can always add a <style> element right before your content.

<style>#project-slide-1:before { color: #ff0000; }</style>
<div id="project-slide-1" class="project-slide"> ... </div>

Example use case with PHP and some (wordpress inspired) dummy functions:

<style>#project-slide-<?php the_ID() ?>:before { color: <?php the_field('color') ?>; }</style>
<div id="project-slide-<?php the_ID() ?>" class="project-slide"> ... </div>

Since HTML 5.2 it is valid to place style elements inside the body, although it is still recommend to place style elements in the head.

Reference: https://www.w3.org/TR/html52/document-metadata.html#the-style-element

Padding is the space between nearest components on the web page and margin is the space from the margin of the webpage.

I had the same problem while following a tutorial on setting up Laravel Homestead for Windows 10. The tutorial provides an example IP address 192.168.10.10 to use for the server. The problem with their example IP is that if you already have a VirtualBox Host-Only Adapter set up, the IP you use for your vagrant server must have the same first three parts of the IP address of your current adapter.

You can check what your current Virtualbox Host-Only Adapter IP address is by running ipconfig (windows) ifconfig (mac/linux) and looking for VirtualBox Host-Only Adapter's IPv4 address. 192.168.56.1 was mine. Usually if the host IP is 192.168.56.1 then the guest IP will be 192.168.56.101 so instead of using the example IP I used 192.168.56.102. Any IP that is within 192.168.56.* that is not already taken should work.

After this homestead up worked perfectly for me.

TL;DR - If your current VirtualBox Host-Only Adapter IP is 192.168.56.1, make your Vagrant server IP 192.168.56.102.

Simple socket server app example

I've already posted a client example at: https://stackoverflow.com/a/35971718/895245 , so here goes a server example.

This example app runs a server that returns a ROT-1 cypher of the input.

You would then need to add an Exit button + some sleep delays, but this should get you started.

To play with it:

• install the app
• get your phone and PC on a LAN
• find your phone's IP with https://android.stackexchange.com/a/130468/126934
• run netcat $PHONE_IP 12345
• type some lines

Android sockets are the same as Java's, except we have to deal with some permission issues.

FileNotFound is just an unfortunate exception used to indicate that the web server returned a 404.

from otherfile import TheClass
theclass = TheClass()
# if you want to return the output of run
return theclass.run()  
# if you want to return run itself to be used later
return theclass.run

Change the end of comm system to:

if __name__ == '__main__':
    a_game = Comm_system()
    a_game.run()

It's those lines being always run that are causing it to be run when imported as well as when executed.

When git clone asks for a password, there's probably a problem with your local machine. My problem was that I was using a custom path for saving the ssh key and that path wasn't visible to git. Either use the default path suggested to you or add the file in the custom location using ssh-add <file>

This is caused because there is a database running on your computer. In my case, it was an Oracle data base. By default, everytime you start your computer, the services of the database automatically starts.

Go to Start >> find Oracle or whatever data-base in the list of programms >> and manually stop the database. It appears that there is a conflict of port.

About the INT, TINYINT... These are different data types, INT is 4-byte number, TINYINT is 1-byte number. More information here - INTEGER, INT, SMALLINT, TINYINT, MEDIUMINT, BIGINT.

The syntax of TINYINT data type is TINYINT(M), where M indicates the maximum display width (used only if your MySQL client supports it).

Numeric Type Attributes.

~1 means 'parent', ~2 'grandparent, etc.

FatJar can help you in this case.

In addition to the"Export as Jar" function which is included to Eclipse the Plug-In bundles all dependent JARs together into one executable jar.
The Plug-In adds the Entry "Build Fat Jar" to the Context-Menu of Java-projects

This is useful if your final exported jar includes other external jars.

If you have Ganymede, the Export Jar dialog is enough to export your resources from your project.

After Ganymede, you have:

mysqldump -u (user) -p(passwd) -h (host_or_IP) database_to_backup > backup_file.sql

example:

mysqldump -u god -pheaven -h 10.0.10.10 accounting > accounting_20141209.sql

this would create sql backup file for the accounting database on server 10.0.10.10. Sometimes your error is seen when localhost is not in config. Designating ip of server may help.

You are limited to small list of functions for text data type.

All I can suggest is start with PATINDEX, but work backwards from DATALENGTH-1, DATALENGTH-2, DATALENGTH-3 etc until you get a result or end up at zero (DATALENGTH-DATALENGTH)

This really is something that SQL Server 2000 simply can't handle.

Edit for other answers : REVERSE is not on the list of functions that can be used with text data in SQL Server 2000

What you're asking for isn't impossible, but it's probably not what you actually want.

Instead of trying to save the screen output to a file, just write the output to a file instead of to the screen.

Like this:

with open('outfile.txt', 'w') as outfile:
    print >>outfile, 'Data collected on:', input['header']['timestamp'].date()

Just add that >>outfile into all your print statements, and make sure everything is indented under that with statement.

More generally, it's better to use string formatting rather than magic print commas, which means you can use the write function instead. For example:

outfile.write('Data collected on: {}'.format(input['header']['timestamp'].date()))

But if print is already doing what you want as far as formatting goes, you can stick with it for now.

What if you've got some Python script someone else wrote (or, worse, a compiled C program that you don't have the source to) and can't make this change? Then the answer is to wrap it in another script that captures its output, with the subprocess module. Again, you probably don't want that, but if you do:

output = subprocess.check_output([sys.executable, './otherscript.py'])
with open('outfile.txt', 'wb') as outfile:
    outfile.write(output)

Draw the image on the background of a JPanel that is added to the frame. Use a layout manager to normally add your buttons and other components to the panel. If you add other child panels, perhaps you want to set child.setOpaque(false).

The main difference between struts & spring MVC is about the difference between Aspect Oriented Programming (AOP) & Object oriented programming (OOP).

Spring makes application loosely coupled by using Dependency Injection.The core of the Spring Framework is the IoC container.

OOP can do everything that AOP does but different approach. In other word, AOP complements OOP by providing another way of thinking about program structure.

Practically, when you want to apply same changes for many files. It should be exhausted work with Struts to add same code for tons of files. Instead Spring write new changes somewhere else and inject to the files.

Some related terminologies of AOP is cross-cutting concerns, Aspect, Dependency Injection...

If you are on Linux/Unix have a look at mbstowcs() and wcstombs() defined in GNU C (from ISO C 90).

• mbs stand for "Multi Bytes String" and is basically the usual zero terminated C string.

• wcs stand for Wide Char String and is an array of wchar_t.

For more background details on wide chars have a look at glibc documentation here.

There is another scenario where this issue reproduces (as in my case). When THE CLIENT REQUEST doesn't contain the right extension on the url, the controller can't identify the desired result format.

For example: the controller is set to respond_to :json (as a single option, without a HTML response)- while the client call is set to /reservations instead of /reservations.json.

Bottom line, change the client call to /reservations.json.

Try Environment Script Plugin (GitHub) which is very similar to EnvInject. It allows you to run a script before the build (after SCM checkout) that generates environment variables for it. E.g.

and in your script, you can print e.g. FOO=bar to the standard output to set that variable.

Example to append to an existing PATH-style variable:

echo PATH+unique_identifier=/usr/local/bin

So you're free to do whatever you need in the script - either cat a file, or run a script in some other language from your project's source tree, etc.

This is called type methods, and are called with dot syntax, like instance methods. However, you call type methods on the type, not on an instance of that type. Here’s how you call a type method on a class called SomeClass:

• utf8_bin compares the bits blindly. No case folding, no accent stripping.
• utf8_general_ci compares one byte with one byte. It does case folding and accent stripping, but no 2-character comparisions: ij is not equal ? in this collation.
• utf8_*_ci is a set of language-specific rules, but otherwise like unicode_ci. Some special cases: Ç, C, ch, ll
• utf8_unicode_ci follows an old Unicode standard for comparisons. ij=?, but ae != æ
• utf8_unicode_520_ci follows an newer Unicode standard. ae = æ

See collation chart for details on what is equal to what in various utf8 collations.

utf8, as defined by MySQL is limited to the 1- to 3-byte utf8 codes. This leaves out Emoji and some of Chinese. So you should really switch to utf8mb4 if you want to go much beyond Europe.

The above points apply to utf8mb4, after suitable spelling change. Going forward, utf8mb4 and utf8mb4_unicode_520_ci are preferred.

• utf16 and utf32 are variants on utf8; there is virtually no use for them.
• ucs2 is closer to "Unicode" than "utf8"; there is virtually no use for it.

declare a double value and convert to long convert to string and formated to float the double value finally replace all the value like 123456789,0000 to 123456789

Double value = double value ;
Long longValue = value.longValue();  String strCellValue1 = new String(longValue.toString().format("%f",value).replaceAll("\\,?0*$", ""));

To prevent this dialog box from appearing, do the following:

1. Right click on the setup.exe for the Oracle 11g 32-bit client, and select Properties.
2. Select the Compatibility tab, and set the Compatibility mode to Windows 7. Click OK to close the Properties tab.
3. Double click setup.exe to install the client.

In addition to Alex's answer:

Note that http://server/resource/id?force_delete=true identifies a different resource than http://server/resource/id. For example, it is a huge difference whether you delete /customers/?status=old or /customers/.

Using bootstrap, if you need to also add some values to the option to use for filters or other stuff you can simply add the class "bs-title-option" to the option that you want as a placeholder:

<select class="form-group">
   <option class="bs-title-option" value="myVal">My PlaceHolder</option>
   <option>A</option>
   <option>B</option>
   <option>c</option>
</select>

Bootstrap adds this class to the title attribute.

Here's another solution that avoids the use of jObject.CreateReader(), and instead creates a new JsonTextReader (which is the behavior used by the default JsonCreate.Deserialze method:

public abstract class JsonCreationConverter<T> : JsonConverter
{
    protected abstract T Create(Type objectType, JObject jObject);

    public override bool CanConvert(Type objectType)
    {
        return typeof(T).IsAssignableFrom(objectType);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        if (reader.TokenType == JsonToken.Null)
            return null;

        // Load JObject from stream
        JObject jObject = JObject.Load(reader);

        // Create target object based on JObject
        T target = Create(objectType, jObject);

        // Populate the object properties
        StringWriter writer = new StringWriter();
        serializer.Serialize(writer, jObject);
        using (JsonTextReader newReader = new JsonTextReader(new StringReader(writer.ToString())))
        { 
            newReader.Culture = reader.Culture;
            newReader.DateParseHandling = reader.DateParseHandling;
            newReader.DateTimeZoneHandling = reader.DateTimeZoneHandling;
            newReader.FloatParseHandling = reader.FloatParseHandling;
            serializer.Populate(newReader, target);
        }

        return target;
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        serializer.Serialize(writer, value);
    }
}

This may work for you:

Scenario 1: primitive types

string keyToMatchInDict = "x";
int newValToAdd = 1;
Dictionary<string,int> dictToUpdate = new Dictionary<string,int>{"x",1};

if(!dictToUpdate.ContainsKey(keyToMatchInDict))
   dictToUpdate.Add(keyToMatchInDict ,newValToAdd );
else
   dictToUpdate[keyToMatchInDict] = newValToAdd; //or you can do operations such as ...dictToUpdate[keyToMatchInDict] += newValToAdd;

Scenario 2: The approach I used for a List as Value

int keyToMatch = 1;
AnyObject objInValueListToAdd = new AnyObject("something for the Ctor")
Dictionary<int,List<AnyObject> dictToUpdate = new Dictionary<int,List<AnyObject>(); //imagine this dict got initialized before with valid Keys and Values...

if(!dictToUpdate.ContainsKey(keyToMatch))
   dictToUpdate.Add(keyToMatch,new List<AnyObject>{objInValueListToAdd});
else
   dictToUpdate[keyToMatch] = objInValueListToAdd;

Hope it's useful for someone in need of help.

I didn't find this solution here. It removes all of it using the cowplot package:

library(cowplot)

p + theme_nothing() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)

Just noticed that the same thing can be accomplished using theme.void() like this:

p + theme_void() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)

If you need to insert node/element in some specific place , you can to do next steps

1. Divide original xml into two parts
2. Append your new node/element as child to first first(the first part should ended with element after wich you wanna add your element )
3. Append second part to the new document.

It is simple algorithm but should works...

A simple way is to implement ajaxError:

Whenever an Ajax request completes with an error, jQuery triggers the ajaxError event. Any and all handlers that have been registered with the .ajaxError() method are executed at this time.

For example:

$('.log').ajaxError(function() {
  $(this).text('Triggered ajaxError handler.');
});

I would suggest reading the ajaxError documentation. It does more than the simple use-case demonstrated above - mainly its callback accepts a number of parameters:

$('.log').ajaxError(function(e, xhr, settings, exception) {
  if (settings.url == 'ajax/missing.html') {
    $(this).text('Triggered ajaxError handler.');
  }
});

See response on this thread that has worked for me:

NOTE - Additional STEP 3 that has made the difference for me compared to similar approaches suggested here

In short:

Step 1 - Generate config for Jupyter Notebook:

jupyter notebook --generate-config

Step 2 - Edit the config file using "nano" or other editor

The config fileshould be under your home directory under ".jupyter" folder:

~/.jupyter/jupyter_notebook_config.py

Step 3 - Disable launching browser by redirecting file

First comment out the line, then change True to False:

c.NotebookApp.use_redirect_file = False

Step 4 - add a line to your .bashrc file to set the BROWSER path

export BROWSER='/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe'

For me it was Chrome under my Windows Program File. Otherwise any linux installation under WSL doesn't have a native browser to launch, so need to set it to the Windows executable.

Step 5 - restart .bashrc

source .bashrc

check it useing loop for each index in comboxlist.Items[i]

bool CheckedOrUnchecked= comboxlist.CheckedItems.Contains(comboxlist.Items[0]);

I think it solve your purpose

You are calling setTimeout() ten times in a row, so they all expire almost at the same time. What you actually want is this:

window.onload = function start() {
    slide(10);
}
function slide(repeats) {
    if (repeats > 0) {
        document.getElementById('container').style.marginLeft='-600px';
        document.getElementById('container').style.marginLeft='-1200px';
        document.getElementById('container').style.marginLeft='-1800px';
        document.getElementById('container').style.marginLeft='0px';
        window.setTimeout(
          function(){
            slide(repeats - 1)
          },
          3000
        );
    }
}

This will call slide(10), which will then set the 3-second timeout to call slide(9), which will set timeout to call slide(8), etc. When slide(0) is called, no more timeouts will be set up.
