Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

I think you'd only want to do this if the member data was pretty large (e.g., an object of another pretty hefty class), and you have some external routine which only works on references to objects of that class. You don't want to copy the member object, so this lets you pass it around.

Or you could use:

android.os.SystemClock.sleep(checkEvery)

which has the advantage of not requiring a wrapping try ... catch.

It declares a type based on what is assigned to it in the initialisation.

A simple example is that the code:

var i = 53;

Will examine the type of 53, and essentially rewrite this as:

int i = 53;

Note that while we can have:

long i = 53;

This won't happen with var. Though it can with:

var i = 53l; // i is now a long

Similarly:

var i = null; // not allowed as type can't be inferred.
var j = (string) null; // allowed as the expression (string) null has both type and value.

This can be a minor convenience with complicated types. It is more important with anonymous types:

var i = from x in SomeSource where x.Name.Length > 3 select new {x.ID, x.Name};
foreach(var j in i)
  Console.WriteLine(j.ID.ToString() + ":" + j.Name);

Here there is no other way of defining i and j than using var as there is no name for the types that they hold.

Tried with Selenium 3.141.0 and chromedriver 73.0.3683.68, this works,

from selenium import webdriver

chromedriver = '/usr/local/bin/chromedriver'
chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_argument('window-size=1366x768')
chromeOptions.add_argument('disable-extensions')
cdriver = webdriver.Chrome(options=chromeOptions, executable_path=chromedriver)

cdriver.get('url')
element = cdriver.find_element_by_css_selector('.some-css.selector')

element.screenshot_as_png('elemenent.png')

No need to get a full image and get a section of a fullscreen image.

I don't believe that Distinct() is guaranteed to maintain the order of the set.

Try pulling out an anonymous type first and distinct/sort on that before you convert to string:

var ud = env.Select(d => new 
                         {
                             d.ReportDate.Year,
                             d.ReportDate.Month,
                             FormattedDate = d.ReportDate.ToString("yyyy-MMM")
                         })
            .Distinct()
            .OrderByDescending(d => d.Year)
            .ThenByDescending(d => d.Month)
            .Select(d => d.FormattedDate);

If you're talking about the database password, as opposed to the password coming from a browser, the standard practice seems to be to put the database password in a PHP config file on the server.

You just need to be sure that the php file containing the password has appropriate permissions on it. I.e. it should be readable only by the web server and by your user account.

If we look at the source code, we will see AsyncTask and Handler is purely written in Java. (There are some exceptions, though. But that is not an important point)

So there is no magic in AsyncTask or Handler. These classes make our life easier as a developer.

For example: If Program A calls method A(), method A() could run in a different thread with Program A. We can easily verify by following code:

Thread t = Thread.currentThread();    
int id = t.getId();

Why should we use a new thread for some tasks? You can google for it. Many many reasons,e.g: lifting heavily, long-running works.

So, what are the differences between Thread, AsyncTask, and Handler?

AsyncTask and Handler are written in Java (internally they use a Thread), so everything we can do with Handler or AsyncTask, we can achieve using a Thread too.

What can Handler and AsyncTask really help?

The most obvious reason is communication between the caller thread and the worker thread. (Caller Thread: A thread which calls the Worker Thread to perform some tasks. A caller thread doesn't necessarily have to be the UI thread). Of course, we can communicate between two threads in other ways, but there are many disadvantages (and dangers) because of thread safety.

That is why we should use Handler and AsyncTask. These classes do most of the work for us, we only need to know which methods to override.

The difference between Handler and AsyncTask is: Use AsyncTask when Caller thread is a UI Thread. This is what android document says:

AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers

I want to emphasize two points:

1) Easy use of the UI thread (so, use when caller thread is UI Thread).

2) No need to manipulate handlers. (means: You can use Handler instead of AsyncTask, but AsyncTask is an easier option).

There are many things in this post I haven't said yet, for example: what is UI Thread, or why it's easier. You must know some methods behind each class and use it, you will completely understand the reason why.

@: when you read the Android document, you will see:

Handler allows you to send and process Message and Runnable objects associated with a thread's MessageQueue

This description might seem strange at first. We only need to understand that each thread has each message queue (like a to-do list), and the thread will take each message and do it until the message queue is empty (just like we finish our work and go to bed). So, when Handler communicates, it just gives a message to caller thread and it will wait to process.

Complicated? Just remember that Handler can communicate with the caller thread safely.

Tracing the root cause, i finally found that the public key of type dsa is not added to the authorized keys on remote server. Appending the same worked for me.

thanks everyone.

Here you go:

function encodeQueryData(data) {
   const ret = [];
   for (let d in data)
     ret.push(encodeURIComponent(d) + '=' + encodeURIComponent(data[d]));
   return ret.join('&');
}

Usage:

const data = { 'first name': 'George', 'last name': 'Jetson', 'age': 110 };
const querystring = encodeQueryData(data);

make an example:

var body = document.body,
    btn = document.getElementById( 'id' );
body.addEventListener( 'click', function( event ) {
    console.log( event.currentTarget === body );
    console.log( event.target === btn );
}, false );

when you click 'btn', and 'true' and 'true' will be appeared!

Your project has to have a builder set for it. If there is not one Eclipse will default to Ant. Which you can use you have to create an Ant build file, which you can Google how to do. It is rather involved though. This is not required to run locally in Eclipse though. If your class is run-able. It looks like yours is, but we can not see all of it.

If you look at your project build path do you have an output folder selected? If you check that folder have the compiled class files been put there? If not the something is not set in Eclpise for it to know to compile. You might check to see if auto build is set for your project.

Here is a complete answer from hmkcode.com

If we have such JSON data

// JSON Data
var articles = [
    { 
        "title":"Title 1",
        "url":"URL 1",
        "categories":["jQuery"],
        "tags":["jquery","json","$.each"]
    },
    {
        "title":"Title 2",
        "url":"URL 2",
        "categories":["Java"],
        "tags":["java","json","jquery"]
    }
];

And we want to view in this Table structure

<table id="added-articles" class="table">
            <tr>
                <th>Title</th>
                <th>Categories</th>
                <th>Tags</th>
            </tr>
        </table>

The following JS code will fill create a row for each JSON element

// 1. remove all existing rows
$("tr:has(td)").remove();

// 2. get each article
$.each(articles, function (index, article) {

    // 2.2 Create table column for categories
    var td_categories = $("<td/>");

    // 2.3 get each category of this article
    $.each(article.categories, function (i, category) {
        var span = $("<span/>");
        span.text(category);
        td_categories.append(span);
    });

    // 2.4 Create table column for tags
   var td_tags = $("<td/>");

    // 2.5 get each tag of this article    
    $.each(article.tags, function (i, tag) {
        var span = $("<span/>");
        span.text(tag);
        td_tags.append(span);
    });

    // 2.6 Create a new row and append 3 columns (title+url, categories, tags)
    $("#added-articles").append($('<tr/>')
            .append($('<td/>').html("<a href='"+article.url+"'>"+article.title+"</a>"))
            .append(td_categories)
            .append(td_tags)
    ); 
});  

POCO is a plain old CLR object, which represent the state and behavior of the application in terms of its problem domain. it is a pure class, without inheritance, without any attributes. Example:

public class Customer
{
    public int Id { get; set; }

    public string Name { get; set; }
}

If you store your colorcodes in a global variable you should be able to access it from either javascript file.

You would normally do a Response.Flush followed by a Response.Close, but for some reason the iTextSharp library doesn't seem to like this. The data doesn't make it through and Adobe thinks the PDF is corrupt. Leave out the Response.Close function and see if your results are better:

Response.Clear();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-disposition", "attachment; filename=file.pdf"); // open in a new window
Response.OutputStream.Write(outStream.GetBuffer(), 0, outStream.GetBuffer().Length);
Response.Flush();

// For some reason, if we close the Response stream, the PDF doesn't make it through
//Response.Close();

Here's the painful route:

    SSLContext ctx = null;
    try {
        KeyStore trustStore;
        trustStore = KeyStore.getInstance("JKS");
        trustStore.load(new FileInputStream("C:\\truststore_client"),
                "asdfgh".toCharArray());
        TrustManagerFactory tmf = TrustManagerFactory
                .getInstance("SunX509");
        tmf.init(trustStore);
        ctx = SSLContext.getInstance("SSL");
        ctx.init(null, tmf.getTrustManagers(), null);
    } catch (NoSuchAlgorithmException e1) {
        e1.printStackTrace();
    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (CertificateException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }
    ClientConfig config = new DefaultClientConfig();
    config.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
            new HTTPSProperties(null, ctx));

    WebResource service = Client.create(config).resource(
            "https://localhost:9999/");
    service.addFilter(new HTTPBasicAuthFilter(username, password));

    // Attempt to view the user's page.
    try {
        service.path("user/" + username).get(String.class);
    } catch (Exception e) {
        e.printStackTrace();
    }

Gotta love those six different caught exceptions :). There are certainly some refactoring to simplify the code a bit. But, I like delfuego's -D options on the VM. I wish there was a javax.net.ssl.trustStore static property that I could just set. Just two lines of code and done. Anyone know where that would be?

This may be too much to ask, but, ideally the keytool would not be used. Instead, the trustedStore would be created dynamically by the code and the cert is added at runtime.

There must be a better answer.

See the documentation of Pattern.

Assuming US-ASCII alphabet (a-z, A-Z), you could use \p{Alnum}.

A regex to check that a line contains only such characters is "^[\\p{Alnum}]*$".

That also matches empty string. To exclude empty string: "^[\\p{Alnum}]+$".

You can use it as follows,

<td>

<input type="submit" name="save" class="noborder" id="save" value="Save" alt="Save" 
tabindex="4" />

</td>

<td>

<input type="submit" name="publish" class="noborder" id="publish" value="Publish" 
alt="Publish" tabindex="5" />

</td>

And in PHP,

<?php
if($_POST['save'])
{
   //Save Code
}
else if($_POST['publish'])
{
   //Publish Code
}
?>

It sets result to the (unsigned) value resulting from putting the 8 bits of value in the lowest 8 bits of result.

The reason something like this is necessary is that byte is a signed type in Java. If you just wrote:

int result = value;

then result would end up with the value ff ff ff fe instead of 00 00 00 fe. A further subtlety is that the & is defined to operate only on int values¹, so what happens is:

1. value is promoted to an int (ff ff ff fe).
2. 0xff is an int literal (00 00 00 ff).
3. The & is applied to yield the desired value for result.

(The point is that conversion to int happens before the & operator is applied.)

1_{Well, not quite. The & operator works on long values as well, if either operand is a long. But not on byte. See the Java Language Specification, sections 15.22.1 and 5.6.2.}

I am going to show you two methods by which you can dynamically apply ng-class

Step-1

By using ternary operator

<div ng-class="condition?'class1':'class2'"></div>

Output

If your condition is true then class1 will be applied to your element else class2 will be applied.

Disadvantage

When you will try to change the conditional value at run time the class somehow will not changed. So I will suggest you to go for step2 if you have requirement like dynamic class change.

Step-2

<div ng-class="{value1:'class1', value2:'class2'}[condition]"></div>

Output

if your condition matches with value1 then class1 will be applied to your element, if matches with value2 then class2 will be applied and so on. And dynamic class change will work fine with it.

Hope this will help you.

I had a look at the answers and many seem to recommend to use nvarchar over varchar, because space is not a problem anymore, so there is no harm in enabling Unicode for little extra storage. Well, this is not always true when you want to apply an index over your column. SQL Server has a limit of 900 bytes on the size of the field you can index. So if you have a varchar(900) you can still index it, but not varchar(901). With nvarchar, the number of characters is halved, so you can index up to nvarchar(450). So if you are confident you don't need nvarchar, I don't recommend using it.

In general, in databases, I recommend sticking to the size you need, because you can always expand. For example, a colleague at work once thought that there is no harm in using nvarchar(max) for a column, as we have no problem with storage at all. Later on, when we tried to apply an index over this column, SQL Server rejected this. If, however, he started with even varchar(5), we could have simply expanded it later to what we need without such a problem that will require us to do a field migration plan to fix this problem.

Not escaping double quotes is the cause of OP's problem. A readable approach to escape double quotes is using backticks (MDN). Here is a sample solution:

my_btn.setAttribute('onclick', `my_func("${onclick_var1}", "${onclick_var2}")`);

To show both string.Split and Regex usage:

string input = "abc][rfd][5][,][.";
string[] parts1 = input.Split(new string[] { "][" }, StringSplitOptions.None);
string[] parts2 = Regex.Split(input, @"\]\[");

Another trick for getting sequential pieces (beyond the seq solution already mentioned) is to use a short logical vector and use vector recycling:

foo[ c( rep(FALSE, 5), TRUE ) ]

I know there are bunch of very well crafted answers. I found a correct documentation from apple website where they have specified the specification for screenshot requirements. Here is the link below https://help.apple.com/app-store-connect/#/devd274dd925

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

Thank you @dfsq for the very helpful code!

I've made some adjustments and maybe some others like them too. I ensured that you can search for multiple words, without having a strict match.

Example rows:

• Apples and Pears
• Apples and Bananas
• Apples and Oranges
• ...

You could search for 'ap pe' and it would recognise the first row
You could search for 'banana apple' and it would recognise the second row

Demo: http://jsfiddle.net/JeroenSormani/xhpkfwgd/1/

var $rows = $('#table tr');
$('#search').keyup(function() {
  var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase().split(' ');

  $rows.hide().filter(function() {
    var text = $(this).text().replace(/\s+/g, ' ').toLowerCase();
    var matchesSearch = true;
    $(val).each(function(index, value) {
      matchesSearch = (!matchesSearch) ? false : ~text.indexOf(value);
    });
    return matchesSearch;
  }).show();
});

childView.bringToFront() didn't work for me, so I set the Z translation of the least recently added item (the one that was overlaying all other children) to a negative value like so:

Encoding.GetString Method (Byte[]) convert bytes to a string.

When overridden in a derived class, decodes all the bytes in the specified byte array into a string.

Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)

Syntax

public virtual string GetString(byte[] bytes)

Parameters

bytes
    Type: System.Byte[]
    The byte array containing the sequence of bytes to decode.

Return Value

Type: System.String
A String containing the results of decoding the specified sequence of bytes.

Exceptions

ArgumentException        - The byte array contains invalid Unicode code points.
ArgumentNullException    - bytes is null.
DecoderFallbackException - A fallback occurred (see Character Encoding in the .NET Framework for complete explanation) or DecoderFallback is set to DecoderExceptionFallback.

Remarks

If the data to be converted is available only in sequential blocks (such as data read from a stream) or if the amount of data is so large that it needs to be divided into smaller blocks, the application should use the Decoder or the Encoder provided by the GetDecoder method or the GetEncoder method, respectively, of a derived class.

See the Remarks under Encoding.GetChars for more discussion of decoding techniques and considerations.

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

As in Swift 3.x for upload image with parameter we can use below alamofire upload method-

static func uploadImageData(inputUrl:String,parameters:[String:Any],imageName: String,imageFile : UIImage,completion:@escaping(_:Any)->Void) {

        let imageData = UIImageJPEGRepresentation(imageFile , 0.5)

        Alamofire.upload(multipartFormData: { (multipartFormData) in

            multipartFormData.append(imageData!, withName: imageName, fileName: "swift_file\(arc4random_uniform(100)).jpeg", mimeType: "image/jpeg")

            for key in parameters.keys{
                let name = String(key)
                if let val = parameters[name!] as? String{
                    multipartFormData.append(val.data(using: .utf8)!, withName: name!)
                }
            }
        }, to:inputUrl)
        { (result) in
            switch result {
            case .success(let upload, _, _):

                upload.uploadProgress(closure: { (Progress) in
                })

                upload.responseJSON { response in

                    if let JSON = response.result.value {
                        completion(JSON)
                    }else{
                        completion(nilValue)
                    }
                }

            case .failure(let encodingError):
                completion(nilValue)
            }

        }

    }

Note: Additionally if our parameter is array of key-pairs then we can use

 var arrayOfKeyPairs = [[String:Any]]()
 let json = try? JSONSerialization.data(withJSONObject: arrayOfKeyPairs, options: [.prettyPrinted])
 let jsonPresentation = String(data: json!, encoding: .utf8)

Use the /i with xcopy and if the directory doesn't exist it will create the directory for you.

There are method join for string objects:

".".join(("a","b","c"))

Use column selection. Column selection is one of the unique features of Sublime2; it is used to give you multiple matched cursors (tutorial here). To get multiple cursors, do one of the following:

Mouse:

• Hold down the shift (Windows/Linux) or option key (Mac) while selecting a region with the mouse.

• Clicking middle mouse button (or scroll) will select as a column also.

Keyboard:

• Select the desired region.
• Type control+shift+L (Windows/Linux) or command+shift+L (Mac)

You now have multiple lines selected, so you could type a quotation mark at the beginning and end of each line. It would be better to take advantage of Sublime's capabilities, and just type ". When you do this, Sublime automatically quotes the selected text.

Type esc to exit multiple cursor mode.

For those of you using Django 1.6 or newer, note that execute_manager was removed. There is a solution posted in the second SO answer here.

you can use altsoft xml2pdf lib for this

It's good practice to use a context manager or call close() in case of exceptions during the file saving process. Could happen if your storage backend is down, etc.

Any overwrite behavior should be configured in your storage backend. For example S3Boto3Storage has a setting AWS_S3_FILE_OVERWRITE. If you're using FileSystemStorage you can write a custom mixin.

You might also want to call the model's save method instead of the FileField's save method if you want any custom side-effects to happen, like last-updated timestamps. If that's the case, you can also set the name attribute of the file to the name of the file - which is relative to MEDIA_ROOT. It defaults to the full path of the file which can cause problems if you don't set it - see File.__init__() and File.name.

Here's an example where self is the model instance where my_file is the FileField / ImageFile, calling save() on the whole model instance instead of just FileField:

import os
from django.core.files import File

with open(filepath, 'rb') as fi:
    self.my_file = File(fi, name=os.path.basename(fi.name))
    self.save()

A lot of these answers have horrid rounding errors because they're casting numbers from one type to another. How about:

double x=123.456;
double fractionalPart = x-Math.floor(x);
double wholePart = Math.floor(x);

It works in bootstrap 4, there were some changes in documentation.We don't need prefix col-, just offset-md-3 e.g.

<div class="row">
   <div class="offset-md-3 col-md-6"> Some content...
   </div>
</div>

Here doc.

OP is using python, but in javascript (something to be careful of since the syntaxes are similar.

// only replaces the first instance of ' ' with '_'
"one two three".replace(' ', '_'); 
=> "one_two three"

// replaces all instances of ' ' with '_'
"one two three".replace(/\s/g, '_');
=> "one_two_three"

I had the same problem and solved it in probably not the best way but it works. I replaced all line breaks before I did my real match:

mystring= Regex.Replace(mystring, "\r\n", "")

I am manipulating HTML so line breaks don't really matter to me in this case.

I tried all of the suggestions above with no luck, I am using .Net 3.5 FYI

If you use eclipse (Eclipse can put utf8 code for you even you write utf8 character. You will see normal utf8 character when you programming but background will be utf8 code) ;

1. Select Project
2. Right click and select Properties
3. Select Resource on Resource Panel(Top of right menu which opened after 2.)
4. You can see in Resource Panel, Text File Encoding, select other which you want

P.S : this will ok if you static value in code. For Example String test = "IIIIIiiiiiiççççç";

A big thank you to @Musa and here is a neat function that converts the data to a base64 string. This may come handy to you when handling a binary file (pdf, png, jpeg, docx, ...) file in a WebView that gets the binary file but you need to transfer the file's data safely into your app.

// runs a get/post on url with post variables, where:
// url ... your url
// post ... {'key1':'value1', 'key2':'value2', ...}
//          set to null if you need a GET instead of POST req
// done ... function(t) called when request returns
function getFile(url, post, done)
{
   var postEnc, method;
   if (post == null)
   {
      postEnc = '';
      method = 'GET';
   }
   else
   {
      method = 'POST';
      postEnc = new FormData();
      for(var i in post)
         postEnc.append(i, post[i]);
   }
   var xhr = new XMLHttpRequest();
   xhr.onreadystatechange = function() {
      if (this.readyState == 4 && this.status == 200)
      {
         var res = this.response;
         var reader = new window.FileReader();
         reader.readAsDataURL(res); 
         reader.onloadend = function() { done(reader.result.split('base64,')[1]); }
      }
   }
   xhr.open(method, url);
   xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
   xhr.send('fname=Henry&lname=Ford');
   xhr.responseType = 'blob';
   xhr.send(postEnc);
}

isset is intended to be used only for variables and not just values, so isset("foobar") will raise an error. As of PHP 5.5, empty supports both variables and expressions.

So your first question should rather be if isset returns true for a variable that holds an empty string. And the answer is:

$var = "";
var_dump(isset($var));

The type comparison tables in PHP’s manual is quite handy for such questions.

isset basically checks if a variable has any value other than null since non-existing variables have always the value null. empty is kind of the counter part to isset but does also treat the integer value 0 and the string value "0" as empty. (Again, take a look at the type comparison tables.)

I needed to load the settings file synchronously, and this was my solution:

export function InitConfig(config: AppConfig) { return () => config.load(); }

import { Injectable } from '@angular/core';

@Injectable()
export class AppConfig {
    Settings: ISettings;

    constructor() { }

    load() {
        return new Promise((resolve) => {
            this.Settings = this.httpGet('assets/clientsettings.json');
            resolve(true);
        });
    }

    httpGet(theUrl): ISettings {
        const xmlHttp = new XMLHttpRequest();
        xmlHttp.open( 'GET', theUrl, false ); // false for synchronous request
        xmlHttp.send( null );
        return JSON.parse(xmlHttp.responseText);
    }
}

This is then provided as a app_initializer which is loaded before the rest of the application.

app.module.ts

{
      provide: APP_INITIALIZER,
      useFactory: InitConfig,
      deps: [AppConfig],
      multi: true
    },

There is no built-in functions to do that in Php (shame ^^). You want to compare a date string to today, you could use a simple substr to achieve it:

if (substr($timestamp, 0, 10) === date('Y.m.d')) { today }
elseif (substr($timestamp, 0, 10) === date('Y.m.d', strtotime('-1 day')) { yesterday }

No date conversion, simple.

CSS "classes" are not OOP "classes". The inheritance works the other way around.
A DOM element can have many classes, either directly or inherited or otherwise associated, which will all be applied in order, overriding earlier defined properties:

<div class="foo bar">

.foo {
    color: blue;
    width: 200px;
}

.bar {
    color: red;
}

The div will be 200px wide and have the color red.

You override properties of DOM elements with different classes, not properties of CSS classes. CSS "classes" are rulesets, the same way ids or tags can be used as rulesets.

Note that the order in which the classes are applied depends on the precedence and specificity of the selector, which is a complex enough topic in itself.

Here is the solution which worked for me.

OUTPUT: State of Cart Widget is updated, upon addition of items.

Create a globalKey for the widget you want to update by calling the trigger from anywhere

final GlobalKey<CartWidgetState> cartKey = GlobalKey();

Make sure it's saved in a file have global access such that, it can be accessed from anywhere. I save it in globalClass where is save commonly used variables through the app's state.

class CartWidget extends StatefulWidget {

  CartWidget({Key key}) : super(key: key);
  @override
  CartWidgetState createState() => CartWidgetState();
}

class CartWidgetState extends State<CartWidget> {
  @override
  Widget build(BuildContext context) {
    //return your widget
    return Container();
  }
}

Call your widget from some other class.

class HomeScreen extends StatefulWidget {

  HomeScreen ({Key key}) : super(key: key);
  @override
  HomeScreenState createState() => HomeScreen State();
}

class HomeScreen State extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {
    return ListView(
              children:[
                 ChildScreen(), 
                 CartWidget(key:cartKey)
              ]
            );
  }
}



class ChildScreen extends StatefulWidget {

  ChildScreen ({Key key}) : super(key: key);
  @override
  ChildScreenState createState() => ChildScreen State();
}

class ChildScreen State extends State<ChildScreen> {
  @override
  Widget build(BuildContext context) {
    return InkWell(
              onTap: (){
                // This will update the state of your inherited widget/ class
                if (cartKey.currentState != null)
                    cartKey.currentState.setState(() {});
              },
              child: Text("Update The State of external Widget"),
           );
  }
}

Add Spring annotation @Repository over the repository class.

I know it should work without this annotation. But if you add this, IntelliJ will not show error.

@Repository
public interface YourRepository ...
...

If you use Spring Data with extending Repository class it will be conflict pagkages. Then you must indicate explicity pagkages.

import org.springframework.data.repository.Repository;
...

@org.springframework.stereotype.Repository
public interface YourRepository extends Repository<YourClass, Long> {
    ...
}

And next you can autowired your repository without errors.

@Autowired
YourRepository yourRepository;

It probably is not a good solution (I guess you are trying to register repositorium twice). But work for me and don't show errors.

Maybe in the new version of IntelliJ can be fixed: https://youtrack.jetbrains.com/issue/IDEA-137023

You can use html5 tag to download the image directly

<?php
$file = "Bang.png"; //Let say If I put the file name Bang.png
echo "<a href='download.php?nama=".$file."' download>donload</a> ";
?>

This is not of much value in Java (1.5+) except when the type of object is Boolean. In which case, this can still be handy.

if (object = null) will not cause compilation failure in Java 1.5+ if object is Boolean but would throw a NullPointerException at runtime.

If you want to filter the models by applicationname and the remaining models by surname:

List<Model> newList = list.Where(m => m.application == "applicationname")
    .Select(m => new Model { 
        application = m.application, 
        users = m.users.Where(u => u.surname == "surname").ToList() 
    }).ToList();

As you can see, it needs to create new models and user-lists, hence it is not the most efficient way.

If you instead don't want to filter the list of users but filter the models by users with at least one user with a given username, use Any:

List<Model> newList = list
    .Where(m => m.application == "applicationname"
            &&  m.users.Any(u => u.surname == "surname"))
    .ToList();

In rxjs v6, of operator should be imported as import { of } from 'rxjs';

Sometimes you can get away with the tee function from itertools, it returns multiple iterators for the same generator that can be used independently.

/*
 * The extendStrArray() method will takes a number "n" and

 */
private String[] extendStrArray(int n, String[] strArray){
    String[] old_str_array = strArray;
    String[] new_str_array = new String[(old_str_array.length + n)];
    for(int i = 0; i < old_str_array.length; i++ ){
        new_str_array[i] = old_str_array[i];
    }//end for loop

    return new_str_array;

}//end extendStrArray()

Basically I would use it like this:

String[] students = {"Tom", "Jeff", "Ashley", "Mary"};
// 4 new students enter the class so we need to extend the string array
students = extendStrArray(4, students); //this will effectively add 4 new empty positions to the "students" array.

In my case I got this error because I was wrongly setting InnerText to a div with html inside it.

Example:

SuccessMessagesContainer.InnerText = "";

   <div class="SuccessMessages ui-state-success" style="height: 25px; display: none;" id="SuccessMessagesContainer" runat="server">

            <td style="width: 80px; vertical-align: middle; height: 18px; text-align: center;">
               <img src="<%=Image_success_icn %>" style="margin: 0 auto; height: 18px;
                  width: 18px;" />
            </td>

      </table>
   </div>

First, a definition, since it's pretty important: A stable sort is one that's guaranteed not to reorder elements with identical keys.

Recommendations:

Quick sort: When you don't need a stable sort and average case performance matters more than worst case performance. A quick sort is O(N log N) on average, O(N^2) in the worst case. A good implementation uses O(log N) auxiliary storage in the form of stack space for recursion.

Merge sort: When you need a stable, O(N log N) sort, this is about your only option. The only downsides to it are that it uses O(N) auxiliary space and has a slightly larger constant than a quick sort. There are some in-place merge sorts, but AFAIK they are all either not stable or worse than O(N log N). Even the O(N log N) in place sorts have so much larger a constant than the plain old merge sort that they're more theoretical curiosities than useful algorithms.

Heap sort: When you don't need a stable sort and you care more about worst case performance than average case performance. It's guaranteed to be O(N log N), and uses O(1) auxiliary space, meaning that you won't unexpectedly run out of heap or stack space on very large inputs.

Introsort: This is a quick sort that switches to a heap sort after a certain recursion depth to get around quick sort's O(N^2) worst case. It's almost always better than a plain old quick sort, since you get the average case of a quick sort, with guaranteed O(N log N) performance. Probably the only reason to use a heap sort instead of this is in severely memory constrained systems where O(log N) stack space is practically significant.

Insertion sort: When N is guaranteed to be small, including as the base case of a quick sort or merge sort. While this is O(N^2), it has a very small constant and is a stable sort.

Bubble sort, selection sort: When you're doing something quick and dirty and for some reason you can't just use the standard library's sorting algorithm. The only advantage these have over insertion sort is being slightly easier to implement.

Non-comparison sorts: Under some fairly limited conditions it's possible to break the O(N log N) barrier and sort in O(N). Here are some cases where that's worth a try:

Counting sort: When you are sorting integers with a limited range.

Radix sort: When log(N) is significantly larger than K, where K is the number of radix digits.

Bucket sort: When you can guarantee that your input is approximately uniformly distributed.

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

In order to import your .sql try the following steps

1. Start SQL Server Management Studio
2. Connect to your Database
3. Open the Query Editor
4. Drag and Drop your .sql File into the editor
5. Execute the import

1.first check if express is install at correct location. 2. npm install express (run this command). 3. express will save under your "node_modules" folder

I don't have idea why it is happening but there 3 trivial attempts to make:

1. Use android:textAllCaps="false" in your layout-v21

2. Programmatically change the transformation method of the button. mButton.setTransformationMethod(null);

3. Check your style for Allcaps

Note: public void setAllCaps(boolean allCaps), android:textAllCaps are available from API version 14.

delete arr[1]

Try this out, it should work if you have an array like var arr =["","",""]

The dynamic keyword was added, together with many other new features of C# 4.0, to make it simpler to talk to code that lives in or comes from other runtimes, that has different APIs.

Take an example.

If you have a COM object, like the Word.Application object, and want to open a document, the method to do that comes with no less than 15 parameters, most of which are optional.

To call this method, you would need something like this (I'm simplifying, this is not actual code):

object missing = System.Reflection.Missing.Value;
object fileName = "C:\\test.docx";
object readOnly = true;
wordApplication.Documents.Open(ref fileName, ref missing, ref readOnly,
    ref missing, ref missing, ref missing, ref missing, ref missing,
    ref missing, ref missing, ref missing, ref missing, ref missing,
    ref missing, ref missing);

Note all those arguments? You need to pass those since C# before version 4.0 did not have a notion of optional arguments. In C# 4.0, COM APIs have been made easier to work with by introducing:

1. Optional arguments
2. Making ref optional for COM APIs
3. Named arguments

The new syntax for the above call would be:

wordApplication.Documents.Open(@"C:\Test.docx", ReadOnly: true);

See how much easier it looks, how much more readable it becomes?

Let's break that apart:

                                    named argument, can skip the rest
                                                   |
                                                   v
wordApplication.Documents.Open(@"C:\Test.docx", ReadOnly: true);
                                 ^                         ^
                                 |                         |
                               notice no ref keyword, can pass
                               actual parameter values instead

The magic is that the C# compiler will now inject the necessary code, and work with new classes in the runtime, to do almost the exact same thing that you did before, but the syntax has been hidden from you, now you can focus on the what, and not so much on the how. Anders Hejlsberg is fond of saying that you have to invoke different "incantations", which is a sort of pun on the magic of the whole thing, where you typically have to wave your hand(s) and say some magic words in the right order to get a certain type of spell going. The old API way of talking to COM objects was a lot of that, you needed to jump through a lot of hoops in order to coax the compiler to compile the code for you.

Things break down in C# before version 4.0 even more if you try to talk to a COM object that you don't have an interface or class for, all you have is an IDispatch reference.

If you don't know what it is, IDispatch is basically reflection for COM objects. With an IDispatch interface you can ask the object "what is the id number for the method known as Save", and build up arrays of a certain type containing the argument values, and finally call an Invoke method on the IDispatch interface to call the method, passing all the information you've managed to scrounge together.

The above Save method could look like this (this is definitely not the right code):

string[] methodNames = new[] { "Open" };
Guid IID = ...
int methodId = wordApplication.GetIDsOfNames(IID, methodNames, methodNames.Length, lcid, dispid);
SafeArray args = new SafeArray(new[] { fileName, missing, missing, .... });
wordApplication.Invoke(methodId, ... args, ...);

All this for just opening a document.

VB had optional arguments and support for most of this out of the box a long time ago, so this C# code:

wordApplication.Documents.Open(@"C:\Test.docx", ReadOnly: true);

is basically just C# catching up to VB in terms of expressiveness, but doing it the right way, by making it extendable, and not just for COM. Of course this is also available for VB.NET or any other language built on top of the .NET runtime.

You can find more information about the IDispatch interface on Wikipedia: IDispatch if you want to read more about it. It's really gory stuff.

However, what if you wanted to talk to a Python object? There's a different API for that than the one used for COM objects, and since Python objects are dynamic in nature as well, you need to resort to reflection magic to find the right methods to call, their parameters, etc. but not the .NET reflection, something written for Python, pretty much like the IDispatch code above, just altogether different.

And for Ruby? A different API still.

JavaScript? Same deal, different API for that as well.

The dynamic keyword consists of two things:

1. The new keyword in C#, dynamic
2. A set of runtime classes that knows how to deal with the different types of objects, that implement a specific API that the dynamic keyword requires, and maps the calls to the right way of doing things. The API is even documented, so if you have objects that comes from a runtime not covered, you can add it.

The dynamic keyword is not, however, meant to replace any existing .NET-only code. Sure, you can do it, but it was not added for that reason, and the authors of the C# programming language with Anders Hejlsberg in the front, has been most adamant that they still regard C# as a strongly typed language, and will not sacrifice that principle.

This means that although you can write code like this:

dynamic x = 10;
dynamic y = 3.14;
dynamic z = "test";
dynamic k = true;
dynamic l = x + y * z - k;

and have it compile, it was not meant as a sort of magic-lets-figure-out-what-you-meant-at-runtime type of system.

The whole purpose was to make it easier to talk to other types of objects.

There's plenty of material on the internet about the keyword, proponents, opponents, discussions, rants, praise, etc.

I suggest you start with the following links and then google for more:

• DevDays 2010: Anders Hejlsberg - C# 4.0 and beyond
• Channel 9: Mads Torgersen - Inside C# 4.0: dynamic typing + +
• DevX: COM Interop Gets Much Better in C# 4.0
• Scott Hanselman - C# 4 and the dynamic keyword - Whirlwind Tour around .NET 4 (and Visual Studio 2010) Beta 1

Or you could simply use

I don't know if this can be related to the OP's post but I was missing the [HttpGet] annotation and that was what was causing the error, as stated by @dinesh_ravva methods are assumed to be HttpPost by default.

• Private: It is an access specifier. By default the instance (member) variables or the methods of a class in c++/java are private. During inheritance, the code and the data are always inherited but is not accessible outside the class. We can declare our data members as private so that no one can make direct changes to our member variables and we can provide public getters and setters in order to change our private members. And this concept is always applied in the business rule.

• Protected: It is also an access specifier. In C++, the protected members are accessible within the class and to the inherited class but not outside the class. In Java, the protected members are accessible within the class, to the inherited class as well as to all the classes within the same package.

I haven't tried it yet, but it looks like NuGet Package Explorer should be able to do it:

https://github.com/NuGetPackageExplorer/NuGetPackageExplorer

(or like Colonel Panic says, 7-zip should probably do it)

Not jQuery, but it works well for a calendar with time: JavaScript Date Time Picker.

I just bound the click event to pop it up:

$(".arrival-date").click(function() {
    NewCssCal($(this).attr('id'), 'mmddyyyy', 'dropdown', true, 12);
});

This will give you the deadline :

select id,  
       title,
       created_at + interval '1' day * claim_window as deadline
from projects

Alternatively the function make_interval can be used:

select id,  
       title,
       created_at + make_interval(days => claim_window) as deadline
from projects

To get all projects where the deadline is over, use:

select *
from (
  select id, 
         created_at + interval '1' day * claim_window as deadline
  from projects
) t
where localtimestamp at time zone 'UTC' > deadline

This was happening to me with Visual Studio 2015 and ReSharper Ultimate 10.0.2. I tried pretty much all the solutions written prior to this answer (apart from any reinstallations) and nothing worked.

I got it working again with a variety of the above steps in a very specific order:

1. ReSharper ? Options ? Environment ? General ? Clear Caches
   • this must be done before suspending ReSharper as otherwise this option is unavailable
   • this clears out the files in C:\Users\YourUsername\AppData\Local\JetBrains\Transient\ReSharperPlatformVs14\v04 as mentioned in some other posts
2. Tools ? Options ? ReSharper Ultimate ? Suspend
3. Close Visual Studio
   • this actually performs the ReSharper cache clear
4. Open Visual Studio
5. Open the solution
   • I waited for Visual Studio to detect there were no code issues in IntelliSense and may have performed a build at this point.
6. Tools ? Options ? ReSharper Ultimate ? Resume

Hopefully after the last step you can breathe a sigh of relief that you don't have to reinstall anything, I certainly did!

You can redirect stdout to nul to hide it.

COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >nul

Just add >nul to the commands you want to hide the output from.

Here you can see all the different ways of redirecting the std streams.

Using DataBinding :

@BindingAdapter({"bind:font"})
public static void setFont(TextView textView, String fontName){
 textView.setTypeface(Typeface.createFromAsset(textView.getContext().getAssets(), "fonts/" + fontName));
}

In XML:

<TextView
app:font="@{`Source-Sans-Pro-Regular.ttf`}"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

font file must be in assets/fonts/

The difference between

import java.util.*;

and

import java.util.*;
import java.util.List;
import java.util.Arrays;

becomes apparent when the code refers to some other List or Arrays (for example, in the same package, or also imported generally). In the first case, the compiler will assume that the Arrays declared in the same package is the one to use, in the latter, since it is declared specifically, the more specific java.util.Arrays will be used.

Write a script with two curl requests in desired order and run it by cron, like

#!/bin/bash
curl http://mysite.com/?update_=1
curl http://mysite.com/?the_other_thing

To compare entire revisions, it's simply:

svn diff -r 8979:11390

If you want to compare the last committed state against your currently saved working files, you can use convenience keywords:

svn diff -r PREV:HEAD

(Note, without anything specified afterwards, all files in the specified revisions are compared.)

You can compare a specific file if you add the file path afterwards:

svn diff -r 8979:HEAD /path/to/my/file.php

This worked for me.

   var regex = /(&nbsp;|<([^>]+)>)/ig
      ,   body = tt
     ,   result = body.replace(regex, "");
       alert(result);

#!/bin/bash
kernel="2.6.39";
distro="xyz";

cat > /etc/myconfig.conf << EOL
line 1, ${kernel}
line 2,
line 3, ${distro}
line 4
line ...
EOL

this does what you want.

I wanted to have the screen resolution before opening the first of my windows, so here a quick solution to open an invisible window before actually measuring screen dimensions (you need to adapt the window parameters to your window in order to ensure that both are openend on the same screen - mainly the WindowStartupLocation is important)

Window w = new Window();
w.ResizeMode = ResizeMode.NoResize;
w.WindowState = WindowState.Normal;
w.WindowStyle = WindowStyle.None;
w.Background = Brushes.Transparent;
w.Width = 0;
w.Height = 0;
w.AllowsTransparency = true;
w.IsHitTestVisible = false;
w.WindowStartupLocation = WindowStartupLocation.Manual;
w.Show();
Screen scr = Screen.FromHandle(new WindowInteropHelper(w).Handle);
w.Close();

Actualy the Gabin Smith's answer needs to be changed a bit to work, because you can't resume with without an error.

Sub MyFunc()
...
    For Each oSheet In ActiveWorkbook.Sheets
        On Error GoTo errHandler:
        Set qry = oSheet.ListObjects(1).QueryTable
        oCmbBox.AddItem oSheet.name

    ...
NextSheet:
    Next oSheet

...
Exit Sub

errHandler:
Resume NextSheet        
End Sub

A Bit late to the party, but I like this solution quite a bit.

CREATE FUNCTION ExplodeDates(@startDate DateTime, @endDate DateTime)

    SELECT  TOP (DATEDIFF(DAY, @startDate, @endDate) + 1)
            DATEADD(DAY, ROW_NUMBER() OVER(ORDER BY a.object_id) - 1, @startDate) AS DATE
    FROM    sys.all_objects a
            CROSS JOIN sys.all_objects b
            )

There is also a Visual Studio extension called CompareFiles, which does nothing else but adding the "Compare Files" entry to the solution explorer context menu. It invokes the built-in Visual Studio diff tool.

Just in case that someone (like me) doesn't want to install an all-in-one extension like VSCommands...

You need to use \" for escaping " character (\ escape the following character

sed -i 's/\"http://www.fubar.com\"/URL_FUBAR/g'

in case you are interested in reading some data from a .txt file and only extract few columns of that file into a new .txt file with a customized header, the following code might be useful:

# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")

# assign the name for the output file:
seqName <- "seq1_data.txt"

#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx        <- civit_cam$q.x.rad.
qy        <- civit_cam$q.y.rad.
qz        <- civit_cam$q.z.rad.
qw        <- civit_cam$q.w

# From GPS:
gpsT      <- civit_gps$X.gpsTime.sec.
latitude  <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude  <- civit_gps$H.Ell.m.
heading   <- civit_gps$Heading.deg.
pitch     <- civit_gps$pitch.deg.
roll      <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]

#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
                     c(frame_idx),
                     c(qx),
                     c(qy),
                     c(qz),
                     c(qw))
# Write :
cat("#GPSTime,frameIdx,qx,qy,qz,qw\n", file=seqName)
write.table(myData, file = seqName,row.names=FALSE,col.names=FALSE,append=TRUE,sep = ",")

Of course, you should modify this sample script based on your own application.

With recent versions of Matlab, you can use the Table data structure to your advantage. There's even a 'rowfun' operation but I found it easier just to do this:

a = magic(6);
incrementRow = cell2mat(cellfun(@(x) x+1,table2cell(table(a)),'UniformOutput',0))

or here's an older one I had that doesn't require tables, for older Matlab versions.

dataBinner = cell2mat(arrayfun(@(x) Binner(a(x,:),2)',1:size(a,1),'UniformOutput',0)')

You need to first add using Microsoft.Win32; to your code page.

Then you can begin to use the Registry classes:

try
{
    using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))
    {
        if (key != null)
        {
            Object o = key.GetValue("Version");
            if (o != null)
            {
                Version version = new Version(o as String);  //"as" because it's REG_SZ...otherwise ToString() might be safe(r)
                //do what you like with version
            }
        }
    }
}
catch (Exception ex)  //just for demonstration...it's always best to handle specific exceptions
{
    //react appropriately
}

BEWARE: unless you have administrator access, you are unlikely to be able to do much in LOCAL_MACHINE. Sometimes even reading values can be a suspect operation without admin rights.

(Explanation in more details can be found in an archived Microsoft KB article.)

Three things to know:

1. The percent sign is used in batch files to represent command line parameters: %1, %2, ...

2. Two percent signs with any characters in between them are interpreted as a variable:

   echo %myvar%

3. Two percent signs without anything in between (in a batch file) are treated like a single percent sign in a command (not a batch file): %%f

Why's that?

For example, if we execute your (simplified) command line

FOR /f %f in ('dir /b .') DO somecommand %f

in a batch file, rule 2 would try to interpret

%f in ('dir /b .') DO somecommand %

as a variable. In order to prevent that, you have to apply rule 3 and escape the % with an second %:

FOR /f %%f in ('dir /b .') DO somecommand %%f

There are two parts of this problem

1) using a parameter that would not alter an url (using params property):

$stateProvider
    .state('login', {
        params: [
            'toStateName',
            'toParamsJson'
        ],
        templateUrl: 'partials/login/Login.html'
    })

2) passing an object as parameter: Well, there is no direct way how to do it now, as every parameter is converted to string (EDIT: since 0.2.13, this is no longer true - you can use objects directly), but you can workaround it by creating the string on your own

toParamsJson = JSON.stringify(toStateParams);

and in target controller deserialize the object again

originalParams = JSON.parse($stateParams.toParamsJson);

So what is that you are really after? If you want to make sure that something has hit for damage (in this case), why are you not using string.Format

string a = string.Format("You hit someone for {d} damage", damage);

In this way, you have the ability to have the damage qualifier that you are looking for, and are able to calculate that for other parts.

Use the readlink utility from the coreutils package.

MY_PATH=$(readlink -f "$0")

create table test (a int, b int , c int, d int);
alter table test drop column b, d;

Be aware that DROP COLUMN does not physically remove the data, and for fixed length types (int, numeric, float, datetime, uniqueidentifier etc) the space is consumed even for records added after the columns were dropped. To get rid of the wasted space do ALTER TABLE ... REBUILD.

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

As it clearly says in error, names should be enclosed in double quotes instead of single quotes. The string you pass is just not a valid JSON. It should look like

{"http://example.org/about": {"http://purl.org/dc/terms/title": [{"type": "literal", "value": "Anna's Homepage"}]}}

I sometimes use an approach that resembles to the answers using property injection, but keeps the code cleaner. Instead of having a base class/interface with a set of properties, it only contains a (virtual) Initialize()-method that acts as a "poor man's constructor". Then you can let each class handle it's own initialization just as a constructor would, which also adds a convinient way of handling inheritance chains.

If often find myself in situations where I want each class in the chain to initialize its unique properties, and then call its parent's Initialize()-method which in turn initializes the parent's unique properties and so forth. This is especially useful when having different classes, but with a similar hierarchy, for example business objects that are mapped to/from DTO:s.

Example that uses a common Dictionary for initialization:

void Main()
{
    var values = new Dictionary<string, int> { { "BaseValue", 1 }, { "DerivedValue", 2 } };

    Console.WriteLine(CreateObject<Base>(values).ToString());

    Console.WriteLine(CreateObject<Derived>(values).ToString());
}

public T CreateObject<T>(IDictionary<string, int> values)
    where T : Base, new()
{
    var obj = new T();
    obj.Initialize(values);
    return obj;
}

public class Base
{
    public int BaseValue { get; set; }

    public virtual void Initialize(IDictionary<string, int> values)
    {
        BaseValue = values["BaseValue"];
    }

    public override string ToString()
    {
        return "BaseValue = " + BaseValue;
    }
}

public class Derived : Base
{
    public int DerivedValue { get; set; }

    public override void Initialize(IDictionary<string, int> values)
    {
        base.Initialize(values);
        DerivedValue = values["DerivedValue"];
    }

    public override string ToString()
    {       
        return base.ToString() + ", DerivedValue = " + DerivedValue;
    }
}

EDIT Since not so recently by now, MinGW-w64 has "absorbed" one of the toolchain building projects. The downloads can be found here. The installer should work, and allow you to pick a version that you need.

Note the Qt SDK comes with the same toolchain. So if you are developing in Qt and using the SDK, just use the toolchain it comes with.

Another alternative that has up to date toolchains comes from... harhar... a Microsoft developer, none other than STL (Stephan T. Lavavej, isn't that a spot-on name for the maintainer of MSVC++ Standard Library!). You can find it here. It includes Boost.

Another option which is highly useful if you care for prebuilt dependencies is MSYS2, which provides a Unix shell (a Cygwin fork modified to work better with Windows pathnames and such), also provides a GCC. It usually lags a bit behind, but that is compensated for by its good package management system and stability. They also provide a functional Clang with libc++ if you care for such thing.

I leave the below for reference, but I strongly suggest against using MinGW.org, due to limitations detailed below. TDM-GCC (the MinGW-w64 version) provides some hacks that you may find useful in your specific situation, although I recommend using vanilla GCC at all times for maximum compatibility.

GCC for Windows is provided by two projects currently. They both provide a very own implementation of the Windows SDK (headers and libraries) which is necessary because GCC does not work with Visual Studio files.

1. The older mingw.org, which @Mat already pointed you to. They provide only a 32-bit compiler. See here for the downloads you need:

   • Binutils is the linker and resource compiler etc.
   • GCC is the compiler, and is split in core and language packages
   • GDB is the debugger.
   • runtime library is required only for mingw.org
   • You might need to download mingw32-make seperately.
   • For support, you can try (don't expect friendly replies) [email protected]

   Alternatively, download mingw-get and use that.

2. The newer mingw-w64, which as the name predicts, also provides a 64-bit variant, and in the future hopefully some ARM support. I use it and built toolchains with their CRT. Personal and auto builds are found under "Toolchains targetting Win32/64" here. They also provide Linux to Windows cross-compilers. I suggest you try a personal build first, they are more complete. Try mine (rubenvb) for GCC 4.6 to 4.8, or use sezero's for GCC 4.4 and 4.5. Both of us provide 32-bit and 64-bit native toolchains. These packages include everything listed above. I currently recommend the "MinGW-Builds" builds, as these are currently sanctioned as "official builds", and come with an installer (see above).

   For support, send an email to [email protected] or post on the forum via sourceforge.net.

Both projects have their files listed on sourceforge, and all you have to do is either run the installer (in case of mingw.org) or download a suitable zipped package and extract it (in the case of mingw-w64).

There are a lot of "non-official" toolchain builders, one of the most popular is TDM-GCC. They may use patches that break binary compatibility with official/unpatched toolchains, so be careful using them. It's best to use the official releases.

Converting to a DATE or using an open-ended date range in any case will yield the best performance. FYI, convert to date using an index are the best performers. More testing a different techniques in article: What is the most efficient way to trim time from datetime? Posted by Aaron Bertrand

From that article:

DECLARE @dateVar datetime = '19700204';

-- Quickest when there is an index on t.[DateColumn], 
-- because CONVERT can still use the index.
SELECT t.[DateColumn]
FROM MyTable t
WHERE = CONVERT(DATE, t.[DateColumn]) = CONVERT(DATE, @dateVar);

-- Quicker when there is no index on t.[DateColumn]
DECLARE @dateEnd datetime = DATEADD(DAY, 1, @dateVar);
SELECT t.[DateColumn] 
FROM MyTable t
WHERE t.[DateColumn] >= @dateVar AND 
      t.[DateColumn] < @dateEnd;

Also from that article: using BETWEEN, DATEDIFF or CONVERT(CHAR(8)... are all slower.

As many others pointed out if you are trying to add a new element at the end of list then something like, array[array.length-1]=x; should do. But this will replace the existing element.

For something like continuous addition to the array. You can keep track of the index and go on adding elements till you reach end and have the function that does the addition return you the next index, which in turn will tell you how many more elements can fit in the array.

Of course in both the cases the size of array will be predefined. Vector can be your other option since you do not want arraylist, which will allow you all the same features and functions and additionally will take care of incrementing the size.

Coming to the part where you want StringBuffer to array. I believe what you are looking for is the getChars(int srcBegin, int srcEnd,char[] dst,int dstBegin) method. Look into it that might solve your doubts. Again I would like to point out that after managing to get an array out of it, you can still only replace the last existing element(character in this case).

A branch is just a reference to a commit. Until you commit anything to the repository, you don't have any branches. You can see this in a non-bare repository as well.

$ mkdir repo
$ cd repo
$ git init
Initialized empty Git repository in /home/me/repo/.git/
$ git branch
$ touch foo
$ git add foo
$ git commit -m "new file"
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 foo
$ git branch
* master

I had this exact same issue until I realized I hadn't put the image in my Image.xcassets. I was able to drag and drop it into Xcode with Image.xcassets open and after rebuilding, it fixed the problem!

\\. is the simple answer. Here is simple code for your help.

while (line != null) {
    //             
    String[] words = line.split("\\.");
    wr = "";
    mean = "";
    if (words.length > 2) {
        wr = words[0] + words[1];
        mean = words[2];

    } else {
        wr = words[0];
        mean = words[1];
    }
}

this is how I do it.

char[] myEmptyCharArray = "".toCharArray();

Another option you can always consider is Apache Commons. It provides a lot of options.

import org.apache.commons.lang3.builder.CompareToBuilder;

Ex:

public int compare(Person a, Person b){

   return new CompareToBuilder()
     .append(a.getName(), b.getName())
     .append(a.getAddress(), b.getAddress())
     .toComparison();
}

Go to http://dev.mysql.com/downloads/connector/j and with in the dropdown select "Platform Independent" then it will show you the options to download tar.gz file or zip file.

Download zip file and extract it, with in that you will find mysql-connector-XXX.jar file

If you are using maven then you can add the dependency from the link http://mvnrepository.com/artifact/mysql/mysql-connector-java

Select the version you want to use and add the dependency in your pom.xml file

I suggest to use BufferedReader for reading text. Scanner hides IOException while BufferedReader throws it immediately.

In order to override setter and getter for swift variables use the below given code

var temX : Int? 
var x: Int?{

    set(newX){
       temX = newX
    }

    get{
        return temX
    }
}

We need to keep the value of variable in a temporary variable, since trying to access the same variable whose getter/setter is being overridden will result in infinite loops.

We can invoke the setter simply like this

x = 10

Getter will be invoked on firing below given line of code

var newVar = x

The Eclipse SDK contains a class SocketUtil, that does what you want. You may have a look into the git source code.

Native Java 8 (one line)

With Java 8, int[] can be converted to Integer[] easily:

int[] data = {1,2,3,4,5,6,7,8,9,10};

// To boxed array
Integer[] what = Arrays.stream( data ).boxed().toArray( Integer[]::new );
Integer[] ever = IntStream.of( data ).boxed().toArray( Integer[]::new );

// To boxed list
List<Integer> you  = Arrays.stream( data ).boxed().collect( Collectors.toList() );
List<Integer> like = IntStream.of( data ).boxed().collect( Collectors.toList() );

As others stated, Integer[] is usually not a good map key. But as far as conversion goes, we now have a relatively clean and native code.

I like ExportHTML, which exports to html, opens it up in your browser, and optionally opens the system print dialog. Looks good, too. Not a perfect replacement for native printing, but pretty close.

You can recursively merge them into one as follows:

function mergeRecursive(obj1, obj2) {_x000D_
    for (var p in obj2) {_x000D_
        try {_x000D_
            // Property in destination object set; update its value._x000D_
            if (obj2[p].constructor == Object) {_x000D_
                obj1[p] = this.mergeRecursive(obj1[p], obj2[p]);_x000D_
_x000D_
            } else {_x000D_
                obj1[p] = obj2[p];_x000D_
_x000D_
            }_x000D_
_x000D_
        } catch (e) {_x000D_
            obj1[p] = obj2[p];_x000D_
_x000D_
        }_x000D_
    }_x000D_
    return obj1;_x000D_
}_x000D_
_x000D_
arr1 = [_x000D_
    { id: "abdc4051", date: "2017-01-24" },_x000D_
    { id: "abdc4052", date: "2017-01-22" }_x000D_
];_x000D_
arr2 = [_x000D_
    { id: "abdc4051", name: "ab" },_x000D_
    { id: "abdc4052", name: "abc" }_x000D_
];_x000D_
_x000D_
mergeRecursive(arr1, arr2)_x000D_
console.log(JSON.stringify(arr1))

I'm guessing you've taken a look at mod_perl?

Have you tried the following tutorial?

EDIT: In relation to your posting - perhaps you could include a sample of the code inside your .cgi file. Perhaps even the first few lines?

I'll try to give the benchmark of the three most common way (also mentioned above):

from timeit import repeat

setup = """
import numpy as np;
import random;
x = np.linspace(0,100);
lb, ub = np.sort([random.random() * 100, random.random() * 100]).tolist()
"""
stmts = 'x[(x > lb) * (x <= ub)]', 'x[(x > lb) & (x <= ub)]', 'x[np.logical_and(x > lb, x <= ub)]'

for _ in range(3):
    for stmt in stmts:
        t = min(repeat(stmt, setup, number=100_000))
        print('%.4f' % t, stmt)
    print()

result:

0.4808 x[(x > lb) * (x <= ub)]
0.4726 x[(x > lb) & (x <= ub)]
0.4904 x[np.logical_and(x > lb, x <= ub)]

0.4725 x[(x > lb) * (x <= ub)]
0.4806 x[(x > lb) & (x <= ub)]
0.5002 x[np.logical_and(x > lb, x <= ub)]

0.4781 x[(x > lb) * (x <= ub)]
0.4336 x[(x > lb) & (x <= ub)]
0.4974 x[np.logical_and(x > lb, x <= ub)]

But, * is not supported in Panda Series, and NumPy Array is faster than pandas data frame (arround 1000 times slower, see number):

from timeit import repeat

setup = """
import numpy as np;
import random;
import pandas as pd;
x = pd.DataFrame(np.linspace(0,100));
lb, ub = np.sort([random.random() * 100, random.random() * 100]).tolist()
"""
stmts = 'x[(x > lb) & (x <= ub)]', 'x[np.logical_and(x > lb, x <= ub)]'

for _ in range(3):
    for stmt in stmts:
        t = min(repeat(stmt, setup, number=100))
        print('%.4f' % t, stmt)
    print()

result:

0.1964 x[(x > lb) & (x <= ub)]
0.1992 x[np.logical_and(x > lb, x <= ub)]

0.2018 x[(x > lb) & (x <= ub)]
0.1838 x[np.logical_and(x > lb, x <= ub)]

0.1871 x[(x > lb) & (x <= ub)]
0.1883 x[np.logical_and(x > lb, x <= ub)]

Note: adding one line of code x = x.to_numpy() will need about 20 µs.

For those who prefer %timeit:

import numpy as np
import random
lb, ub = np.sort([random.random() * 100, random.random() * 100]).tolist()
lb, ub
x = pd.DataFrame(np.linspace(0,100))

def asterik(x):
    x = x.to_numpy()
    return x[(x > lb) * (x <= ub)]

def and_symbol(x):
    x = x.to_numpy()
    return x[(x > lb) & (x <= ub)]

def numpy_logical(x):
    x = x.to_numpy()
    return x[np.logical_and(x > lb, x <= ub)]

for i in range(3):
    %timeit asterik(x)
    %timeit and_symbol(x)
    %timeit numpy_logical(x)
    print('\n')

result:

23 µs ± 3.62 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)
35.6 µs ± 9.53 µs per loop (mean ± std. dev. of 7 runs, 100000 loops each)

An option for delegates in C++ that is not otherwise mentioned here is to do it C style using a function ptr and a context argument. This is probably the same pattern that many asking this question are trying to avoid. But, the pattern is portable, efficient, and is usable in embedded and kernel code.

class SomeClass
{
    in someMember;
    int SomeFunc( int);

    static void EventFunc( void* this__, int a, int b, int c)
    {
        SomeClass* this_ = static_cast< SomeClass*>( this__);

        this_->SomeFunc( a );
        this_->someMember = b + c;
    }
};

void ScheduleEvent( void (*delegateFunc)( void*, int, int, int), void* delegateContext);

    ...
    SomeClass* someObject = new SomeObject();
    ...
    ScheduleEvent( SomeClass::EventFunc, someObject);
    ...

-O is the option to specify the path of the file you want to download to:

wget <uri> -O /path/to/file.ext

-P is prefix where it will download the file in the directory:

wget <uri> -P /path/to/folder

You could also do the following:

// untested
Calendar cal = GregorianCalendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 23);// I might have the wrong Calendar constant...
cal.set(Calendar.MONTH, 8);// -1 as month is zero-based
cal.set(Calendar.YEAR, 2009);
Timestamp tstamp = new Timestamp(cal.getTimeInMillis());

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

You can use list comprehensions for this problem as it will solve it in only two lines. Code-

n = int(input("Enter the range of the list:\n"))
l1 = [i for i in range(n)] #Creates list of numbers in the range 0 to n
if __name__ == "__main__":
    print(l1)

Thank you.

 private List<String> FindString(String stringToLookFor, List<String> arrayToSearchIn)
 {
     List<String> ReceptacleOfWordsFound = new ArrayList<String>();

     if(!arrayToSearchIn.isEmpty())
     {
         for(String lCurrentString : arrayToSearchIn)
         {
             if(lCurrentString.toUpperCase().contains(stringToLookFor.toUpperCase())
                 ReceptacleOfWordsFound.add(lCurrentString);
         }
     }
  return ReceptacleOfWordsFound;
 }

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

Do this way:-

var peoples = [
  { "name": "bob", "dinner": "pizza" },
  { "name": "john", "dinner": "sushi" },
  { "name": "larry", "dinner": "hummus" }
];

$.each(peoples, function(i, val) {
    $.each(val, function(key, name) {
        if (name === "john")
            alert(key + " : " + name);
    });
});

OUTPUT:

name : john

1. Check what security group you are using for your instance. See value of Security Groups column in row of your instance. It's important - I changed rules for default group, but my instance was under quickstart-1 group when I had similar issue.
2. Go to Security Groups tab, go to Inbound tab, select HTTP in Create a new rule combo-box, leave 0.0.0.0/0 in source field and click Add Rule, then Apply rule changes.

I found a solution:

print("My message here");

Look at snprintf or, if GNU extensions are OK, asprintf (which will allocate memory for you).

Just clear the clipboard before closing.

Application.CutCopyMode=False
ActiveWindow.Close

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

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

  // code

  if (c)
  {
    int m, n;

    // more code
  }
  // etc.
}

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

So, you will need to do the following:

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

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

Try to covert both strings to upper or lower case. Then you can use == comparison operator.

This is an old problem with some good information. But what I just found is that using a FQDN turns off the Compat mode in IE 9 - 11. Example. I have the compat problem with
http://lrmstst01:8080/JavaWeb/login.do
but the problems go away with
http://lrmstst01.mydomain.int:8080/JavaWeb/login.do
NB: The .int is part of our internal domain

str() in python on an integer will not print any decimal places.

If you have a float that you want to ignore the decimal part, then you can use str(int(floatValue)).

Perhaps the following code will demonstrate:

>>> str(5)
'5'
>>> int(8.7)
8

There is also a change between Java 7 and Java 8. Admittedly it involves the a deprecated call, but I had to add a "/" to get our program working! Here is the link discussing it Why does servletContext.getRealPath returns null on tomcat 8?

As long as you haven't been sticking the CSS in element.style:

1. Go to a style you have added. There should be a link saying inspector-stylesheet:

2. Click on that, and it will open up all the CSS that you have added in the sources panel

3. Copy and paste it - yay!

If you have been using element.style:

You can just right-click on your HTML element, click Edit as HTML and then copy and paste the HTML with the inline styles.

I have used Open source Web Design in the past. They have quite a few css themes, don't know about ASP.Net

Since the original question is unclear about its requirements, I attempted to solve this problem within the guidelines set by other answers. In particular:

• Align list bullets with outside paragraph text
• Align multiple lines within the same list item

I also wanted a solution that didn't rely on browsers agreeing on how much padding to use. I've added an ordered list for completeness.

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

The bearing calculation is incorrect, you need to swap the inputs to atan2.

    bearing = atan2(sin(long2-long1)*cos(lat2), cos(lat1)*sin(lat2)-sin(lat1)*cos(lat2)*cos(long2-long1))
    bearing = degrees(bearing)
    bearing = (bearing + 360) % 360

This will give you the correct bearing.

Have you tried HttpServerUtility.UrlDecode or HttpUtility.UrlDecode?

For MySQL Workbench

1. Select database from Schemas tab by right mouse clicking.
2. Set database as Default Schema

Nowadays you can use reversed block-based enumeration. A simple example code:

NSMutableArray *array = [@[@{@"name": @"a", @"shouldDelete": @(YES)},
                           @{@"name": @"b", @"shouldDelete": @(NO)},
                           @{@"name": @"c", @"shouldDelete": @(YES)},
                           @{@"name": @"d", @"shouldDelete": @(NO)}] mutableCopy];

[array enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
    if([obj[@"shouldDelete"] boolValue])
        [array removeObjectAtIndex:idx];
}];

Result:

(
    {
        name = b;
        shouldDelete = 0;
    },
    {
        name = d;
        shouldDelete = 0;
    }
)

another option with just one line of code:

[array filterUsingPredicate:[NSPredicate predicateWithFormat:@"shouldDelete == NO"]];

Methods like sleep() and wait() of class Thread might throw an InterruptedException. This will happen if some other thread wanted to interrupt the thread that is waiting or sleeping.

Came across a need to do SQL-style mixed asc and desc object array sorts by keys.

kennebec's solution above helped me get to this:

Array.prototype.keySort = function(keys) {

keys = keys || {};

// via
// https://stackoverflow.com/questions/5223/length-of-javascript-object-ie-associative-array
var obLen = function(obj) {
    var size = 0, key;
    for (key in obj) {
        if (obj.hasOwnProperty(key))
            size++;
    }
    return size;
};

// avoiding using Object.keys because I guess did it have IE8 issues?
// else var obIx = function(obj, ix){ return Object.keys(obj)[ix]; } or
// whatever
var obIx = function(obj, ix) {
    var size = 0, key;
    for (key in obj) {
        if (obj.hasOwnProperty(key)) {
            if (size == ix)
                return key;
            size++;
        }
    }
    return false;
};

var keySort = function(a, b, d) {
    d = d !== null ? d : 1;
    // a = a.toLowerCase(); // this breaks numbers
    // b = b.toLowerCase();
    if (a == b)
        return 0;
    return a > b ? 1 * d : -1 * d;
};

var KL = obLen(keys);

if (!KL)
    return this.sort(keySort);

for ( var k in keys) {
    // asc unless desc or skip
    keys[k] = 
            keys[k] == 'desc' || keys[k] == -1  ? -1 
          : (keys[k] == 'skip' || keys[k] === 0 ? 0 
          : 1);
}

this.sort(function(a, b) {
    var sorted = 0, ix = 0;

    while (sorted === 0 && ix < KL) {
        var k = obIx(keys, ix);
        if (k) {
            var dir = keys[k];
            sorted = keySort(a[k], b[k], dir);
            ix++;
        }
    }
    return sorted;
});
return this;
};

sample usage:

var obja = [
  {USER:"bob",  SCORE:2000, TIME:32,    AGE:16, COUNTRY:"US"},
  {USER:"jane", SCORE:4000, TIME:35,    AGE:16, COUNTRY:"DE"},
  {USER:"tim",  SCORE:1000, TIME:30,    AGE:17, COUNTRY:"UK"},
  {USER:"mary", SCORE:1500, TIME:31,    AGE:19, COUNTRY:"PL"},
  {USER:"joe",  SCORE:2500, TIME:33,    AGE:18, COUNTRY:"US"},
  {USER:"sally",    SCORE:2000, TIME:30,    AGE:16, COUNTRY:"CA"},
  {USER:"yuri", SCORE:3000, TIME:34,    AGE:19, COUNTRY:"RU"},
  {USER:"anita",    SCORE:2500, TIME:32,    AGE:17, COUNTRY:"LV"},
  {USER:"mark", SCORE:2000, TIME:30,    AGE:18, COUNTRY:"DE"},
  {USER:"amy",  SCORE:1500, TIME:29,    AGE:19, COUNTRY:"UK"}
];

var sorto = {
  SCORE:"desc",TIME:"asc", AGE:"asc"
};

obja.keySort(sorto);

yields the following:

(using a print function from here)

here is a jsbin example.

edit: cleaned up and posted as mksort.js on github.

I put together, after having read the answers in this question, a simple function which can also do a callback, if you need that:

function waitFor(ms, cb) {
  var waitTill = new Date(new Date().getTime() + ms);
  while(waitTill > new Date()){};
  if (cb) {
    cb()
  } else {
   return true
  }
}

To pass arguments to your python script while running a script via command line

python create_thumbnail.py test1.jpg test2.jpg

here, script name - create_thumbnail.py, argument 1 - test1.jpg, argument 2 - test2.jpg

With in the create_thumbnail.py script i use

sys.argv[1:]

which give me the list of arguments i passed in command line as ['test1.jpg', 'test2.jpg']

This is my solution:

1. Copy&paste $ANDROID_SDK/extras/android/support/v7/appcompat to your project ROOT

2. Open "Project Structure" on Intellij, click "Modules" on "Project Settings", then click "appcompat"->"android', make sure "Library Module" checkbox is checked.

3. click "YOUR-PROJECT_NAME" under "appcompat", remove "android-support-v4" and "android-support-v7-compat"; ensure the checkbox before "appcompat" is checked. And, click "ok" to close "Project Structure" dialogue.

4. back to the mainwindow, click "appcompat"->"libs" on the top-left project area. Right-click on "android-support-v4", select menuitem "Add as library", change "Add to Module" to "Your-project". Same with "android-support-v7-compat".

After doing above, intellij should be able to correctly find the android-support-XXXX modules.

Good Luck!

select count(*),sum(decode(status, 'ACTIVE',1,0)) from v$session where type= 'USER'

Turn the String into a char[], replace the letter by index, then convert the array back into a String.

String myName = "domanokz";
char[] myNameChars = myName.toCharArray();
myNameChars[4] = 'x';
myName = String.valueOf(myNameChars);

Just for fun

class A {
    private a1 = void 0;
    private a2 = void 0;
}

class B extends A {
    private a3 = void 0;
    private a4 = void 0;
}

class C extends B {
    private a5 = void 0;
    private a6 = void 0;
}

class Describer {
    private static FRegEx = new RegExp(/(?:this\.)(.+?(?= ))/g); 
    static describe(val: Function, parent = false): string[] {
        var result = [];
        if (parent) {
            var proto = Object.getPrototypeOf(val.prototype);
            if (proto) {
                result = result.concat(this.describe(proto.constructor, parent));
            } 
        }
        result = result.concat(val.toString().match(this.FRegEx) || []);
        return result;
    }
}

console.log(Describer.describe(A)); // ["this.a1", "this.a2"]
console.log(Describer.describe(B)); // ["this.a3", "this.a4"]
console.log(Describer.describe(C, true)); // ["this.a1", ..., "this.a6"]

Update: If you are using custom constructors, this functionality will break.

Old thread but for me it started working (after following all advise above) when i renamed int main(void) to int wmain(void) and removed WIN23 from cmake's add_executable().

I would use NSPredicate:

func isValidEmail(_ email: String) -> Bool {        
    let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

    let emailPred = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
    return emailPred.evaluate(with: email)
}

for versions of Swift earlier than 3.0:

func isValidEmail(email: String) -> Bool {
    let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

    let emailPred = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
    return emailPred.evaluate(with: email)
}

for versions of Swift earlier than 1.2:

func isValidEmail(email: String) -> Bool {
    let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

    if let emailPred = NSPredicate(format:"SELF MATCHES %@", emailRegEx) {
        return emailPred.evaluateWithObject(email)
    }
    return false
}

Just click the button to download using following code.

in html

<a class="btn" ng-click="saveJSON()" ng-href="{{ url }}">Export to JSON</a>

In controller

$scope.saveJSON = function () {_x000D_
   $scope.toJSON = '';_x000D_
   $scope.toJSON = angular.toJson($scope.data);_x000D_
   var blob = new Blob([$scope.toJSON], { type:"application/json;charset=utf-8;" });   _x000D_
   var downloadLink = angular.element('<a></a>');_x000D_
                        downloadLink.attr('href',window.URL.createObjectURL(blob));_x000D_
                        downloadLink.attr('download', 'fileName.json');_x000D_
   downloadLink[0].click();_x000D_
  };

i refer so many results and modified my code its working

foreach (var rate in rateing)
                {
                    sum += Convert.ToInt32(rate.Rate);
                }
                if(rateing.Count()!= 0)
                {
                    float avg = (float)sum / (float)rateing.Count();
                    saloonusers.Rate = avg;
                }
                else
                {

No, you can't name the tuple members.

The in-between would be to use ExpandoObject instead of Tuple.

Add this line before any output of the body, in the event you aren't using output buffering.

header("HTTP/1.1 200 OK");

Replace the message portion ('OK') with the appropriate message, and the status code with your code as appropriate (404, 501, etc)

If the forked repo is protected so you can't push directly into it, and your goal is to make changes to their foo, then you need to get their branch foo into your repo like so:

git remote add protected_repo https://github.com/theirusername/their_repo.git
git fetch protected_repo 
git checkout --no-track protected_repo/foo

Now you have a local copy of foo with no upstream associated to it. You can commit changes to it (or not) and then push your foo to your own remote repo.

git push --set-upstream origin foo

Now foo is in your repo on GitHub and your local foo is tracking it. If they continue to make changes to foo you can fetch theirs and merge into your foo.

git checkout foo 
git fetch protected_repo
git merge protected_repo/foo

System.Windows.MessageBox.Show("Hello world"); //WPF
System.Windows.Forms.MessageBox.Show("Hello world"); //WinForms

why not just put the ng-controller one level higher,

<body ng-controller="ProjectController">
    <div ng-view><div>

And don't set controller in the route,

.when('/', { templateUrl: "abc.html" })

it works for me.

This will match yyyy-mm-dd and also yyyy-m-d:

^\d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])$

If you're looking for an exact match for yyyy-mm-dd then try this

^\d{4}\-(0[1-9]|1[012])\-(0[1-9]|[12][0-9]|3[01])$

or use this one if you need to find a date inside a string like The date is 2017-11-30

\d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])*

:last-child is CSS3 and has no IE support while :first-child is CSS2, I believe the following is the safe way to implement it using jquery

$('li').last().addClass('someClass');

You can use heroku logs -n 1500

But this is not a recommended approach(in other word doesn't show you the real picture)

I would suggest you plug some logging tool. ( sumoLogic, paper trail n all ) as an add-on

They all have a free version( with few limitations, though enough for a small app or dev env, which will provide good insight and tool to analyze logs )

You can try it out http://api.jquery.com/mouseover/ on the jQuery doc page. It's a nice little, interactive demo that makes it very clear and you can actually see for yourself.

In short, you'll notice that a mouse over event occurs on an element when you are over it - coming from either its child OR parent element, but a mouse enter event only occurs when the mouse moves from the parent element to the element.

JSFiddle Demonstration

This is what I use with JQuery:

$('.button').on('click', function () { 
    var obj = document.createElement("audio");
        obj.src = "linktoyourfile.wav"; 
        obj.play(); 
});

This way work for me in Swift 2 iOS 8.x:

PS (this method dont require to override orientation functions like shouldautorotate on every viewController, just one method on AppDelegate)

Check the "requires full screen" in you project general info.

So, on AppDelegate.swift make a variable:

var enableAllOrientation = false

So, put also this func:

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
        if (enableAllOrientation == true){
            return UIInterfaceOrientationMask.All
        }
        return UIInterfaceOrientationMask.Portrait
}

So, in every class in your project you can set this var in viewWillAppear:

override func viewWillAppear(animated: Bool)
{
        super.viewWillAppear(animated)
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        appDelegate.enableAllOrientation = true
}

If you need to make a choices based on the device type you can do this:

override func viewWillAppear(animated: Bool)
    {
        super.viewWillAppear(animated)
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        switch UIDevice.currentDevice().userInterfaceIdiom {
        case .Phone:
        // It's an iPhone
           print(" - Only portrait mode to iPhone")
           appDelegate.enableAllOrientation = false
        case .Pad:
        // It's an iPad
           print(" - All orientation mode enabled on iPad")
           appDelegate.enableAllOrientation = true
        case .Unspecified:
        // Uh, oh! What could it be?
           appDelegate.enableAllOrientation = false
        }
    }

According to the official site. These are the two ways

<div>
  {/* Comment goes here */}
  Hello, {name}!
</div>

Second Example:

<div>
    {/* It also works 
    for multi-line comments. */}
    Hello, {name}! 
</div>

Here is the link: https://reactjs.org/docs/faq-build.html#how-can-i-write-comments-in-jsx

Also, in addition to torek's answer: one thing that stands out is that you're using a lazily-evaluated macro assignment.

If you're on GNU Make, use the := assignment instead of =. This assignment causes the right hand side to be expanded immediately, and stored in the left hand variable.

FILES := $(shell ...)  # expand now; FILES is now the result of $(shell ...)

FILES = $(shell ...)   # expand later: FILES holds the syntax $(shell ...)

If you use the = assignment, it means that every single occurrence of $(FILES) will be expanding the $(shell ...) syntax and thus invoking the shell command. This will make your make job run slower, or even have some surprising consequences.

You can handle the fds yourself. The exec in java returns a Process object. Intermittently check if the process is still running. Once it has completed close the processes STDERR, STDIN, and STDOUT streams (e.g. proc.getErrorStream.close()). That will mitigate the leaks.

The problem is the indexing subplot is using. Subplots are counted starting with 1! Your code thus needs to read

fig=plt.figure(figsize=(15, 6),facecolor='w', edgecolor='k')
for i in range(10):

    #this part is just arranging the data for contourf 
    ind2 = py.find(zz==i+1)
    sfr_mass_mat = np.reshape(sfr_mass[ind2],(pixmax_x,pixmax_y))
    sfr_mass_sub = sfr_mass[ind2]
    zi = griddata(massloclist, sfrloclist, sfr_mass_sub,xi,yi,interp='nn')


    temp = 251+i  # this is to index the position of the subplot
    ax=plt.subplot(temp)
    ax.contourf(xi,yi,zi,5,cmap=plt.cm.Oranges)
    plt.subplots_adjust(hspace = .5,wspace=.001)

    #just annotating where each contour plot is being placed
    ax.set_title(str(temp))

Note the change in the line where you calculate temp

Your code makes no sense, maybe because it's out of context.

If you mean code like this:

$('a').click(function () {
    callFunction();
    return false;
});

The return false will return false to the click-event. That tells the browser to stop following events, like follow a link. It has nothing to do with the previous function call. Javascript runs from top to bottom more or less, so a line cannot affect a previous line.

You could also do:

del /s /p *.{your extension here}

The /p will prompt you for each found file, if you're nervous about deleting something you shouldn't.

Do everything d4Rk suggests, that is a great walk-through. if it still isn't signing, you might have some expired or revoked certificates. I find this can happen when you're working on a team.

1. quit xcode.
2. open Keychain Access.
3. in the 'Certificates' section, go through all "iPhone Distribution" certificates and if they're expired or revoked or otherwise invalid, delete them.
4. same as 3, but for the 'My Certificates' section.
5. re-open xcode and try again.

Maybe the problem is Sourcetree.

1. Go to Tools → Options

2. Uncheck "Check default remotes for updates every [10] minutes"

3. Restart Sourcetree!

As you know the string is coming in as Encoding.Default you could simply use:

byte[] bytes = Encoding.Default.GetBytes(myString);
myString = Encoding.UTF8.GetString(bytes);

Another thing you may have to remember: If you are using Console.WriteLine to output some strings, then you should also write Console.OutputEncoding = System.Text.Encoding.UTF8;!!! Or all utf8 strings will be outputed as gbk...

The code that you have is correct. To get a variable from another class you need to create an instance of the class if the variable is not static, and just call the explicit method to get access to that variable. If you put get and set method like the above is the same of declaring that variable public.

Put the method setNum private and inside the getNum assign the value that you want, you will have "get" access to the variable in that case

You will get the un passed argument value as undefined. But in your case you have to pass at least null value in the first argument.

Or you have to change the method definition like

my_function = function(options, content) { action }

You can run below commands.

 ./catalina.sh run

Note: Make sure the port 8080 is open. If not, kill the process that is using 8080 port using sudo kill -9 $(sudo lsof -t -i:8080)

body.addEventListener("load", init(), false);

That init() is saying run this function now and assign whatever it returns to the load event.

What you want is to assign the reference to the function, not the result. So you need to drop the ().

body.addEventListener("load", init, false);

Also you should be using window.onload and not body.onload

addEventListener is supported in most browsers except IE 8.

You should avoid using pool.getConnection() if you can. If you call pool.getConnection(), you must call connection.release() when you are done using the connection. Otherwise, your application will get stuck waiting forever for connections to be returned to the pool once you hit the connection limit.

For simple queries, you can use pool.query(). This shorthand will automatically call connection.release() for you—even in error conditions.

function doSomething(cb) {
  pool.query('SELECT 2*2 "value"', (ex, rows) => {
    if (ex) {
      cb(ex);
    } else {
      cb(null, rows[0].value);
    }
  });
}

However, in some cases you must use pool.getConnection(). These cases include:

• Making multiple queries within a transaction.
• Sharing data objects such as temporary tables between subsequent queries.

If you must use pool.getConnection(), ensure you call connection.release() using a pattern similar to below:

function doSomething(cb) {
  pool.getConnection((ex, connection) => {
    if (ex) {
      cb(ex);
    } else {
      // Ensure that any call to cb releases the connection
      // by wrapping it.
      cb = (cb => {
        return function () {
          connection.release();
          cb.apply(this, arguments);
        };
      })(cb);
      connection.beginTransaction(ex => {
        if (ex) {
          cb(ex);
        } else {
          connection.query('INSERT INTO table1 ("value") VALUES (\'my value\');', ex => {
            if (ex) {
              cb(ex);
            } else {
              connection.query('INSERT INTO table2 ("value") VALUES (\'my other value\')', ex => {
                if (ex) {
                  cb(ex);
                } else {
                  connection.commit(ex => {
                    cb(ex);
                  });
                }
              });
            }
          });
        }
      });
    }
  });
}

I personally prefer to use Promises and the useAsync() pattern. This pattern combined with async/await makes it a lot harder to accidentally forget to release() the connection because it turns your lexical scoping into an automatic call to .release():

async function usePooledConnectionAsync(actionAsync) {
  const connection = await new Promise((resolve, reject) => {
    pool.getConnection((ex, connection) => {
      if (ex) {
        reject(ex);
      } else {
        resolve(connection);
      }
    });
  });
  try {
    return await actionAsync(connection);
  } finally {
    connection.release();
  }
}

async function doSomethingElse() {
  // Usage example:
  const result = await usePooledConnectionAsync(async connection => {
    const rows = await new Promise((resolve, reject) => {
      connection.query('SELECT 2*4 "value"', (ex, rows) => {
        if (ex) {
          reject(ex);
        } else {
          resolve(rows);
        }
      });
    });
    return rows[0].value;
  });
  console.log(`result=${result}`);
}
