Your memcpy code is correct.

My guess is you are lacking an include of string.h. So the compiler assumes a wrong prototype of memcpy and thus the warning.

Anyway, you should just assign the structs for the sake of simplicity (as Joachim Pileborg pointed out).

This way I was able to call MyService

private REST_API_SERVER = 'http://localhost:4040/abc';
public sendGetRequest() {
   var myFormData = { email: '[email protected]', password: '123' };
   const headers = new HttpHeaders();
   headers.append('Content-Type', 'application/json');
   //HTTP POST REQUEST
   this.httpClient
  .post(this.REST_API_SERVER, myFormData, {
    headers: headers,
   })
  .subscribe((data) => {
    console.log("i'm from service............", data, myFormData, headers);
    return data;
  });
}

Perhaps use tikz.

Here's an answer to a 2-year old question in case it helps anyone else with the same problem.

Based upon the information you've provided, a permissions issue on the file (or files) would be one cause of the same 500 Internal Server Error.

To check whether this is the problem (if you can't get more detailed information on the error), navigate to the directory in Terminal and run the following command:

ls -la

If you see limited permissions - e.g. -rw-------@ against your file, then that's your problem.

The solution then is to run chmod 644 on the problem file(s) or chmod 755 on the directories. See this answer - How do I set chmod for a folder and all of its subfolders and files? - for a detailed explanation of how to change permissions.

By way of background, I had precisely the same problem as you did on some files that I had copied over from another Mac via Google Drive, which transfer had stripped most of the permissions from the files.

The screenshot below illustrates. The index.php file with the -rw-------@ permissions generates a 500 Internal Server Error, while the index_finstuff.php (precisely the same content!) with -rw-r--r--@ permissions is fine. Changing the permissions on the index.php immediately resolves the problem.

In other words, your PHP code and the server may both be fine. However, the limited read permissions on the file may be forbidding the server from displaying the content, causing the 500 Internal Server Error message to be displayed instead.

edit build.prop in folder /system if below line is exist change the value and if not exist add this line and save.(device must be rooted)

ro.lge.proximity.delay=25
mot.proximity.delay=25  

You can also use this code to adjust to all carousel images.

.carousel-item{
    width: 100%; /*width you want*/
    height: 500px; /*height you want*/
    overflow: hidden;
}
.carousel-item img{
    width: 100%;
    height: 100%;
    object-fit: cover;
}

How about the Intersection Observer API? This avoids the potential sluggishness from using the scroll event.

HTML

<nav class="navbar-fixed-top">Navbar</nav>
<main>
  <div class="content">Some content</div>
</main>

CSS

.navbar-fixed-top--scrolled changes the nav bar background color. It's added to the nav bar when the content div is no longer 100% visible as we scroll down.

.navbar-fixed-top {
  position: sticky;
  top: 0;
  height: 60px;
}

.navbar-fixed-top--scrolled {
  /* change background-color to whatever you want */
  background-color: grey;
}

JS

Create the observer to determine when the content div fully intersects with the browser viewport.

The callback function is called:

• the first time the observer is initially asked to watch the target element
• when content div is no longer fully visible (due to threshold: 1)
• when content div becomes fully visible (due to threshold: 1)

isIntersecting indicates whether the content div (the target element) is fully intersecting with the observer's root (the browser viewport by default).

// callback function to be run whenever threshold is crossed in one direction or the other
const callback = (entries, observer) => {
  const entry = entries[0];
  
  // toggle class depending on if content div intersects with viewport
  const navBar = document.querySelector('.navbar-fixed-top');
  navBar.classList.toggle('navbar-fixed-top--scrolled', !entry.isIntersecting);
}

// options controls circumstances under which the observer's callback is invoked
const options = {
  // no root provided - by default browser viewport used to check target visibility
  // only detect if target element is fully visible or not
  threshold: [1]
};

const io = new IntersectionObserver(callback, options);

// observe content div 
const target = document.querySelector('.content');
io.observe(target);

IntersectionObserver options

The nav bar currently changes background color when the content div starts moving off the screen.

If we want the background to change as soon as the user scrolls, we can use the rootMargin property (top, right, bottom, left) and set the top margin to negative the height of the nav bar (60px in our case).

const options = {
  rootMargin: "-60px 0px 0px 0px",
  threshold: [1]
};

You can see all the above in action on CodePen. Kevin Powell also has a good explanation on this (Github & YouTube).

As per: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

9.2 OPTIONS

The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the Request-URI. This method allows the client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without implying a resource action or initiating a resource retrieval.

Responses to this method are not cacheable.

If the OPTIONS request includes an entity-body (as indicated by the presence of Content-Length or Transfer-Encoding), then the media type MUST be indicated by a Content-Type field. Although this specification does not define any use for such a body, future extensions to HTTP might use the OPTIONS body to make more detailed queries on the server. A server that does not support such an extension MAY discard the request body.

If the Request-URI is an asterisk ("*"), the OPTIONS request is intended to apply to the server in general rather than to a specific resource. Since a server's communication options typically depend on the resource, the "*" request is only useful as a "ping" or "no-op" type of method; it does nothing beyond allowing the client to test the capabilities of the server. For example, this can be used to test a proxy for HTTP/1.1 compliance (or lack thereof).

If the Request-URI is not an asterisk, the OPTIONS request applies only to the options that are available when communicating with that resource.

A 200 response SHOULD include any header fields that indicate optional features implemented by the server and applicable to that resource (e.g., Allow), possibly including extensions not defined by this specification. The response body, if any, SHOULD also include information about the communication options. The format for such a body is not defined by this specification, but might be defined by future extensions to HTTP. Content negotiation MAY be used to select the appropriate response format. If no response body is included, the response MUST include a Content-Length field with a field-value of "0".

The Max-Forwards request-header field MAY be used to target a specific proxy in the request chain. When a proxy receives an OPTIONS request on an absoluteURI for which request forwarding is permitted, the proxy MUST check for a Max-Forwards field. If the Max-Forwards field-value is zero ("0"), the proxy MUST NOT forward the message; instead, the proxy SHOULD respond with its own communication options. If the Max-Forwards field-value is an integer greater than zero, the proxy MUST decrement the field-value when it forwards the request. If no Max-Forwards field is present in the request, then the forwarded request MUST NOT include a Max-Forwards field.

9.4 HEAD

The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response. The metainformation contained in the HTTP headers in response to a HEAD request SHOULD be identical to the information sent in response to a GET request. This method can be used for obtaining metainformation about the entity implied by the request without transferring the entity-body itself. This method is often used for testing hypertext links for validity, accessibility, and recent modification.

The response to a HEAD request MAY be cacheable in the sense that the information contained in the response MAY be used to update a previously cached entity from that resource. If the new field values indicate that the cached entity differs from the current entity (as would be indicated by a change in Content-Length, Content-MD5, ETag or Last-Modified), then the cache MUST treat the cache entry as stale.

Another reason why this exception occurs is if you call the configure method twice on a Configuration or AnnotatedConfiguration object like this -

AnnotationConfiguration config = new AnnotationConfiguration();
config.addAnnotatedClass(MyClass.class);
//Use this if config files are in src folder
config.configure();
//Use this if config files are in a subfolder of src, such as "resources"
config.configure("/resources/hibernate.cfg.xml");

Btw, this project structure is inside eclipse.

You could give the form and the link some ids and then subscribe for the onclick event of the link and submit the form:

<form id="myform" action="" method="POST">
    <a href="#" id="mylink"> submit </a>
</form>

and then:

window.onload = function() {
    document.getElementById('mylink').onclick = function() {
        document.getElementById('myform').submit();
        return false;
    };
};

I would recommend you using a submit button for submitting forms as it respects the markup semantics and it will work even for users with javascript disabled.

You should run your entire script as superuser. If you want to run some command as non-superuser, use "-u" option of sudo:

#!/bin/bash

sudo -u username command1
command2
sudo -u username command3
command4

When running as root, sudo doesn't ask for a password.

Although @zeller said it already here is an example how to use tasklist. As I was just looking for vanilla python alternatives...

import subprocess

def process_exists(process_name):
    call = 'TASKLIST', '/FI', 'imagename eq %s' % process_name
    # use buildin check_output right away
    output = subprocess.check_output(call).decode()
    # check in last line for process name
    last_line = output.strip().split('\r\n')[-1]
    # because Fail message could be translated
    return last_line.lower().startswith(process_name.lower())

and now you can do:

>>> process_exists('eclipse.exe')
True

>>> process_exists('AJKGVSJGSCSeclipse.exe')
False

To avoid calling this multiple times and have an overview of all the processes this way you could do something like:

# get info dict about all running processes
import subprocess
output = subprocess.check_output(('TASKLIST', '/FO', 'CSV')).decode()
# get rid of extra " and split into lines
output = output.replace('"', '').split('\r\n')
keys = output[0].split(',')
proc_list = [i.split(',') for i in output[1:] if i]
# make dict with proc names as keys and dicts with the extra nfo as values
proc_dict = dict((i[0], dict(zip(keys[1:], i[1:]))) for i in proc_list)
for name, values in sorted(proc_dict.items(), key=lambda x: x[0].lower()):
    print('%s: %s' % (name, values))

Yes, they are all the same.

We can review the interpreted machine code to confirm that that they're all doing the exact same thing.

import dis

def f1():
  print "Hello World"
  return None

def f2():
  print "Hello World"
  return

def f3():
  print "Hello World"

dis.dis(f1)
    4   0 LOAD_CONST    1 ('Hello World')
        3 PRINT_ITEM
        4 PRINT_NEWLINE

    5   5 LOAD_CONST    0 (None)
        8 RETURN_VALUE

dis.dis(f2)
    9   0 LOAD_CONST    1 ('Hello World')
        3 PRINT_ITEM
        4 PRINT_NEWLINE

    10  5 LOAD_CONST    0 (None)
        8 RETURN_VALUE

dis.dis(f3)
    14  0 LOAD_CONST    1 ('Hello World')
        3 PRINT_ITEM
        4 PRINT_NEWLINE            
        5 LOAD_CONST    0 (None)
        8 RETURN_VALUE      

I like Rushyo's suggestion of using AT, but this is another option:

whoami /groups | findstr /b BUILTIN\Administrators | findstr /c:"Enabled group" && goto :isadministrator

This approach would also allow you to distinguish between a non-administrator and a non-elevated administrator if you wanted to. Non-elevated administrators still have BUILTIN\Administrators in the group list but it is not enabled.

However, this will not work on some non-English language systems. Instead, try

whoami /groups | findstr /c:" S-1-5-32-544 " | findstr /c:" Enabled group" && goto :isadministrator

(This should work on Windows 7 but I'm not sure about earlier versions.)

This code snippet:

def decorator(func):
   return func

@decorator
def some_func():
    pass

Is equivalent to this code:

def decorator(func):
    return func

def some_func():
    pass

some_func = decorator(some_func)

In the definition of a decorator you can add some modified things that wouldn't be returned by a function normally.

1. From What's this "serialization" thing all about?:

   It lets you take an object or group of objects, put them on a disk or send them through a wire or wireless transport mechanism, then later, perhaps on another computer, reverse the process: resurrect the original object(s). The basic mechanisms are to flatten object(s) into a one-dimensional stream of bits, and to turn that stream of bits back into the original object(s).

   Like the Transporter on Star Trek, it's all about taking something complicated and turning it into a flat sequence of 1s and 0s, then taking that sequence of 1s and 0s (possibly at another place, possibly at another time) and reconstructing the original complicated "something."

   So, implement the Serializable interface when you need to store a copy of the object, send them to another process which runs on the same system or over the network.

2. Because you want to store or send an object.

3. It makes storing and sending objects easy. It has nothing to do with security.

In Python, the spacing is very important, this gives the structure of your code blocks. This error happens when you mess up your code structure, for example like this :

def test_function() :
   if 5 > 3 :
   print "hello"

You may also have a mix of tabs and spaces in your file.

I suggest you use a python syntax aware editor like PyScripter, or Netbeans

Create a migration that has a change_column statement with a :default => value.

change_column :my_table, :my_column, :integer, :default => 0, :null => false

See: change_column

Depending on the database engine you may need to use change_column_null

Either manually, like

var str = "www.test.com",
    rmv = "www.";

str = str.slice( str.indexOf( rmv ) + rmv.length );

or just use .replace():

str = str.replace( rmv, '' );

please try to make it as a character

string str = "Tigger";
//then str[0] will return 'T' not "T"

I just killed the Oracle processes and re-initiate JBoss. All was fine :)

if you post a file from mobile device or other

    byte[] fileData = null;
    using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
    {
        fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
    }

The JavaScript octal conversion 'feature' is a good one to know about:

parseInt('06') // 6
parseInt('07') // 7
parseInt('08') // 0
parseInt('09') // 0
parseInt('10') // 10

More details here.

The documentation for css() says that setting the style property to the empty string will remove that property if it does not reside in a stylesheet:

Setting the value of a style property to an empty string — e.g. $('#mydiv').css('color', '') — removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's .css() method, or through direct DOM manipulation of the style property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or <style> element.

Since your styles are inline, you can write:

$(selector).css("-moz-user-select", "");

For Kotling here is what I used lately:

// src/main/com.blabla/ShellApplication.kt

/**
 * Main entry point for the shell application.
 */
@SpringBootApplication
public class ShellApplication : CommandLineRunner {
    companion object {
        @JvmStatic
        fun main(args: Array<String>) {
            val application = SpringApplication(ShellApplication::class.java)
            application.webApplicationType = WebApplicationType.NONE
            application.run(*args);
        }
    }

    override fun run(vararg args: String?) {}
}

// src/main/com.blabla/command/CustomCommand.kt

@ShellComponent
public class CustomCommand {
    private val logger = KotlinLogging.logger {}

    @ShellMethod("Import, create and update data from CSV")
    public fun importCsv(@ShellOption() file: String) {
        logger.info("Hi")
    }
}

And everything boot normally ending up with a shell with my custom command available.

As for VS2017, I found it under C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\Hostx64\x64

Thre are 2 ways to run Action Query in MS Access VBA:

1. You can use DoCmd.OpenQuery statement. This allows you to control these warnings:

BUT! Keep in mind that DoCmd.SetWarnings will remain set even after the function completes. This means that you need to make sure that you leave it in a condition that suits your needs

Function RunActionQuery(QueryName As String)
    On Error GoTo Hell              'Set Error Hanlder
    DoCmd.SetWarnings True          'Turn On Warnings
    DoCmd.OpenQuery QueryName       'Execute Action Query
    DoCmd.SetWarnings False         'Turn On Warnings
    Exit Function
Hell:
    If Err.Number = 2501 Then       'If Query Was Canceled
        MsgBox Err.Description, vbInformation
    Else                            'Everything else
        MsgBox Err.Description, vbCritical
    End If
End Function

2. You can use CurrentDb.Execute method. This alows you to keep Action Query failures under control. The SetWarnings flag does not affect it. Query is executed always without warnings.

Function RunActionQuery()
    'To Catch the Query Error use dbFailOnError option
    On Error GoTo Hell
    CurrentDb.Execute "Query1", dbFailOnError
    Exit Function
Hell:
    Debug.Print Err.Description
End Function

It is worth noting that the dbFailOnError option responds only to data processing failures. If the Query contains an error (such as a typo), then a runtime error is generated, even if this option is not specified

In addition, you can use DoCmd.Hourglass True and DoCmd.Hourglass False to control the mouse pointer if your Query takes longer

I like the other suggestions but I would rather not update the machine.config for a single application. I suggest that you just add it to the web.config / app.config. Here is what I needed to use the MySql Connector/NET that I "bin" deployed.

<system.data>
    <DbProviderFactories >
        <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.6.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>
</system.data>

Not a general answer, but may be useful for the specific case where you are happy with the default python 2 encoding, but want to specify utf-8 for python 3:

if sys.version_info.major > 2:
    do_open = lambda filename: open(filename, encoding='utf-8')
else:
    do_open = lambda filename: open(filename)

with do_open(filename) as file:
    pass

In your MoviesService you should import FirebaseListObservable in order to define return type FirebaseListObservable<any[]>

import { AngularFireDatabase, FirebaseListObservable } from 'angularfire2/database';

then get() method should like this-

get (): FirebaseListObservable<any[]>{
        return this.db.list('/movies');
    }

this get() method will return FirebaseListObervable of movies list

In your MoviesComponent should look like this

export class MoviesComponent implements OnInit {
  movies: any[];

  constructor(private moviesDb: MoviesService) { }

  ngOnInit() {
    this.moviesDb.get().subscribe((snaps) => {
       this.movies = snaps;
   });
 }
}

Then you can easily iterate through movies without async pipe as movies[] data is not observable type, your html should be this

ul
  li(*ngFor='let movie of movies')
    {{ movie.title }}

if you declear movies as a

movies: FirebaseListObservable<any[]>;

then you should simply call

movies: FirebaseListObservable<any[]>;
ngOnInit() {
    this.movies = this.moviesDb.get();
}

and your html should be this

ul
  li(*ngFor='let movie of movies | async')
    {{ movie.title }}

Here's a version that should be more general than most; it doesn't require find (using du instead), for instance. It does require xargs, which are only found in some versions of Plan 9 (like 9front).

 du -a | awk -F' '  '{ print $2 }' | xargs sed -i -e 's/subdomainA\.example\.com/subdomainB.example.com/g'

If you want to add filters like file extensions use grep:

 du -a | grep "\.scala$" | awk -F' '  '{ print $2 }' | xargs sed -i -e 's/subdomainA\.example\.com/subdomainB.example.com/g'

$validator = Validator::make($request->all(), [ 'email' => 'required|email', 'password' => 'required', ]);

if ($validator->fails()) { return $validator->errors(); }

I wonder why nobody proposed the possibly simplest solution:

don't use a <form>

A <whatever ng-form> does IMHO a better job and without an HTML form, there's nothing to be submitted by the browser itself. Which is exactly the right behavior when using angular.

I wanted to share another solution working with the ui router 1.0.0.X

As you may know, stateChangeStart and stateChangeSuccess are now deprecated. https://github.com/angular-ui/ui-router/issues/2655

Instead you should use $transitions http://angular-ui.github.io/ui-router/1.0.0-alpha.1/interfaces/transition.ihookregistry.html

This is how I achieved it:

First I have and AuthService with some useful functions

angular.module('myApp')

        .factory('AuthService',
                ['$http', '$cookies', '$rootScope',
                    function ($http, $cookies, $rootScope) {
                        var service = {};

                        // Authenticates throug a rest service
                        service.authenticate = function (username, password, callback) {

                            $http.post('api/login', {username: username, password: password})
                                    .success(function (response) {
                                        callback(response);
                                    });
                        };

                        // Creates a cookie and set the Authorization header
                        service.setCredentials = function (response) {
                            $rootScope.globals = response.token;

                            $http.defaults.headers.common['Authorization'] = 'Bearer ' + response.token;
                            $cookies.put('globals', $rootScope.globals);
                        };

                        // Checks if it's authenticated
                        service.isAuthenticated = function() {
                            return !($cookies.get('globals') === undefined);
                        };

                        // Clear credentials when logout
                        service.clearCredentials = function () {
                            $rootScope.globals = undefined;
                            $cookies.remove('globals');
                            $http.defaults.headers.common.Authorization = 'Bearer ';
                        };

                        return service;
                    }]);

Then I have this configuration:

angular.module('myApp', [
    'ui.router',
    'ngCookies'
])
        .config(['$stateProvider', '$urlRouterProvider',
            function ($stateProvider, $urlRouterProvider) {
                $urlRouterProvider.otherwise('/resumen');
                $stateProvider
                        .state("dashboard", {
                            url: "/dashboard",
                            templateUrl: "partials/dashboard.html",
                            controller: "dashCtrl",
                            data: {
                                authRequired: true
                            }
                        })
                        .state("login", {
                            url: "/login",
                            templateUrl: "partials/login.html",
                            controller: "loginController"
                        })
            }])

        .run(['$rootScope', '$transitions', '$state', '$cookies', '$http', 'AuthService',
            function ($rootScope, $transitions, $state, $cookies, $http, AuthService) {

                // keep user logged in after page refresh
                $rootScope.globals = $cookies.get('globals') || {};
                $http.defaults.headers.common['Authorization'] = 'Bearer ' + $rootScope.globals;

                $transitions.onStart({
                    to: function (state) {
                        return state.data != null && state.data.authRequired === true;
                    }
                }, function () {
                    if (!AuthService.isAuthenticated()) {
                        return $state.target("login");
                    }
                });
            }]);

You can see that I use

data: {
   authRequired: true
}

to mark the state only accessible if is authenticated.

then, on the .run I use the transitions to check the autheticated state

$transitions.onStart({
    to: function (state) {
        return state.data != null && state.data.authRequired === true;
    }
}, function () {
    if (!AuthService.isAuthenticated()) {
        return $state.target("login");
    }
});

I build this example using some code found on the $transitions documentation. I'm pretty new with the ui router but it works.

Hope it can helps anyone.

Try adding the profile attribute to your head tag and use "image/x-icon" for the type attribute:

<head profile="http://www.w3.org/2005/10/profile">
<link rel="icon" type="image/x-icon" href="img/favicon.ico">

If the above code doesn't work, try using the full icon path for the href attribute:

<head profile="http://www.w3.org/2005/10/profile">
<link rel="icon" type="image/x-icon" href="http://example.com/img/favicon.ico">

The least complicated, most straight-forward way of doing this is by simply wrapping your main query with the pivot in a common table expression, then grouping/aggregating.

WITH PivotCTE AS
(
    select * from  mytransactions
    pivot (sum (totalcount) for country in ([Australia], [Austria])) as pvt
)
SELECT
    numericmonth,
    chardate,
    SUM(totalamount) AS totalamount,
    SUM(ISNULL(Australia, 0)) AS Australia,
    SUM(ISNULL(Austria, 0)) Austria
FROM PivotCTE
GROUP BY numericmonth, chardate

The ISNULL is to stop a NULL value from nullifying the sum (because NULL + any value = NULL)

Using this CSS for my current site. It works perfect!

#sides{
margin:0;
}
#left{
float:left;
width:75%;
overflow:hidden;
}
#right{
float:left;
width:25%;
overflow:hidden;
} 

Sorry if this is too verbose or too late, but this was the only way I could find to get the job done. The most complicating factor was the fact that java does not have pass by reference functions, so the get---Extra methods need a default to return and cannot modify a boolean value to tell whether or not the default value is being returned by chance, or because the results were not favorable. For this purpose, it would have been nicer to have the method raise an exception than to have it return a default.

I found my information here: Android Intent Documentation.

    //substitute your own intent here
    Intent intent = new Intent();
    intent.putExtra("first", "hello");
    intent.putExtra("second", 1);
    intent.putExtra("third", true);
    intent.putExtra("fourth", 1.01);
    // convert the set to a string array

Set Documentation

    String[] anArray = {};
    Set<String> extras1 = (Set<String>) intent.getExtras().keySet();
    String[] extras = (String[]) extras1.toArray(anArray);
    // an arraylist to hold all of the strings
    // rather than putting strings in here, you could display them
    ArrayList<String> endResult = new ArrayList<String>();
    for (int i=0; i<extras.length; i++) {
        //try using as a String
        String aString = intent.getStringExtra(extras[i]);
        // is a string, because the default return value for a non-string is null
        if (aString != null) {
            endResult.add(extras[i] + " : " + aString);
        }
        // not a string
        else {
            // try the next data type, int
            int anInt = intent.getIntExtra(extras[i], 0);
            // is the default value signifying that either it is not an int or that it happens to be 0 
            if (anInt == 0) {
                // is an int value that happens to be 0, the same as the default value
                if (intent.getIntExtra(extras[i], 1) != 1) {
                    endResult.add(extras[i] + " : " + Integer.toString(anInt));
                }
                // not an int value
                // try double (also works for float)
                else {
                    double aDouble = intent.getDoubleExtra(extras[i], 0.0);
                    // is the same as the default value, but does not necessarily mean that it is not double
                    if (aDouble == 0.0) {
                        // just happens that it was 0.0 and is a double
                        if (intent.getDoubleExtra(extras[i], 1.0) != 1.0) {
                            endResult.add(extras[i] + " : " + Double.toString(aDouble));
                        }
                        // keep looking...
                        else {
                            // lastly check for boolean
                            boolean aBool = intent.getBooleanExtra(extras[i], false);
                            // same as default, but not necessarily not a bool (still could be a bool)
                            if (aBool == false) {
                                // it is a bool!
                                if (intent.getBooleanExtra(extras[i], true) != true) {
                                    endResult.add(extras[i] + " : " + Boolean.toString(aBool));
                                }
                                else {
                                    //well, the road ends here unless you want to add some more data types
                                }
                            }
                            // it is a bool
                            else {
                                endResult.add(extras[i] + " : " + Boolean.toString(aBool));
                            }
                        }
                    }
                    // is a double
                    else {
                        endResult.add(extras[i] + " : " + Double.toString(aDouble));
                    }
                }
            }
            // is an int value
            else {
                endResult.add(extras[i] + " : " + Integer.toString(anInt));
            }
        }
    }
    // to display at the end
    for (int i=0; i<endResult.size(); i++) {
        Toast.makeText(this, endResult.get(i), Toast.LENGTH_SHORT).show();
    }

Replace

curl_setopt($ch, CURLOPT_POSTFIELDS, array("customer"=>$data_string));

with:

$data_string = json_encode(array("customer"=>$data));
//Send blindly the json-encoded string.
//The server, IMO, expects the body of the HTTP request to be in JSON
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

I dont get what you meant by "other page", I hope it is the page at: 'url_to_post'. If that page is written in PHP, the JSON you just posted above will be read in the below way:

$jsonStr = file_get_contents("php://input"); //read the HTTP body.
$json = json_decode($jsonStr);

Solution that works for me is adding event listener to paste event if you are pasting to a text input. Since paste event happens before text in input changes, inside my on paste handler I create a deferred function inside which I check for changes in my input box that happened on paste:

onPaste: function() {
    var oThis = this;
    setTimeout(function() { // Defer until onPaste() is done
        console.log('paste', oThis.input.value);
        // Manipulate pasted input
    }, 1);
}

LR is link register used to hold the return address for a function call.

SP is stack pointer. The stack is generally used to hold "automatic" variables and context/parameters across function calls. Conceptually you can think of the "stack" as a place where you "pile" your data. You keep "stacking" one piece of data over the other and the stack pointer tells you how "high" your "stack" of data is. You can remove data from the "top" of the "stack" and make it shorter.

From the ARM architecture reference:

SP, the Stack Pointer

Register R13 is used as a pointer to the active stack.

In Thumb code, most instructions cannot access SP. The only instructions that can access SP are those designed to use SP as a stack pointer. The use of SP for any purpose other than as a stack pointer is deprecated. Note Using SP for any purpose other than as a stack pointer is likely to break the requirements of operating systems, debuggers, and other software systems, causing them to malfunction.

LR, the Link Register

Register R14 is used to store the return address from a subroutine. At other times, LR can be used for other purposes.

When a BL or BLX instruction performs a subroutine call, LR is set to the subroutine return address. To perform a subroutine return, copy LR back to the program counter. This is typically done in one of two ways, after entering the subroutine with a BL or BLX instruction:

• Return with a BX LR instruction.

• On subroutine entry, store LR to the stack with an instruction of the form: PUSH {,LR} and use a matching instruction to return: POP {,PC} ...

This link gives an example of a trivial subroutine.

Here is an example of how registers are saved on the stack prior to a call and then popped back to restore their content.

When you make the input, set it to be readonly.

<input type="text" name="datepicker" id="datepicker" readonly="readonly" />

Whatever happens outside the Scope of Angular, Angular will never know that.

Digest cycle put the changes from the model -> controller and then from controller -> model.

If you need to see the latest Model, you need to trigger the digest cycle

But there is a chance of a digest cycle in progress, so we need to check and init the cycle.

Preferably, always perform a safe apply.

       $scope.safeApply = function(fn) {
            if (this.$root) {
                var phase = this.$root.$$phase;
                if (phase == '$apply' || phase == '$digest') {
                    if (fn && (typeof (fn) === 'function')) {
                        fn();
                    }
                } else {
                    this.$apply(fn);
                }
            }
        };


      $scope.safeApply(function(){
          // your function here.
      });

I had to make my VideoView sit in a RelativeLayout in order to make the chosen answer work.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <VideoView android:id="@+id/videoViewRelative"
         android:layout_alignParentTop="true"
         android:layout_alignParentBottom="true"
         android:layout_alignParentLeft="true"
         android:layout_alignParentRight="true"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>

As given here: Android - How to stretch video to fill VideoView area Toggling between screen sizes would be as simple as changing the layout parameters as given in the chosen answer.

Just a minor modification to the excellent answer above by Lessan Vaezi. I ran into a situation where I needed to include attributes in my option entries. The original implementation loses any tag attributes. This version of the above answer preserves the option tag attributes:

jQuery.fn.filterByText = function(textbox) {
  return this.each(function() {
    var select = this;
    var options = [];
    $(select).find('option').each(function() {
      options.push({
          value: $(this).val(),
          text: $(this).text(),
          attrs: this.attributes, // Preserve attributes.
      });
    });
    $(select).data('options', options);

    $(textbox).bind('change keyup', function() {
      var options = $(select).empty().data('options');
      var search = $.trim($(this).val());
      var regex = new RegExp(search, "gi");

      $.each(options, function(i) {
        var option = options[i];
        if (option.text.match(regex) !== null) { 
            var new_option = $('<option>').text(option.text).val(option.value);
            if (option.attrs) // Add old element options to new entry
            {
                $.each(option.attrs, function () {
                    $(new_option).attr(this.name, this.value);
                    });
            }
            
            $(select).append(new_option);
        }
      });
    });
  });
};

string is by default Nullable ,you don't need to do anything to make string Nullable

Gradle put the fun back into building/assembling software. I used ant to build software my entire career and I have always considered the actual "buildit" part of the dev work being a necessary evil. A few months back our company grew tired of not using a binary repo (aka checking in jars into the vcs) and I was given the task to investigate this. Started with ivy since it could be bolted on top of ant, didn't have much luck getting my built artifacts published like I wanted. I went for maven and hacked away with xml, worked splendid for some simple helper libs but I ran into serious problems trying to bundle applications ready for deploy. Hassled quite a while googling plugins and reading forums and wound up downloading trillions of support jars for various plugins which I had a hard time using. Finally I went for gradle (getting quite bitter at this point, and annoyed that "It shouldn't be THIS hard!")

But from day one my mood started to improve. I was getting somewhere. Took me like two hours to migrate my first ant module and the build file was basically nothing. Easily fitted one screen. The big "wow" was: build scripts in xml, how stupid is that? the fact that declaring one dependency takes ONE row is very appealing to me -> you can easily see all dependencies for a certain project on one page. From then on I been on a constant roll, for every problem I faced so far there is a simple and elegant solution. I think these are the reasons:

• groovy is very intuitive for java developers
• documentation is great to awesome
• the flexibility is endless

Now I spend my days trying to think up new features to add to our build process. How sick is that?

As of lodash 3.5.0 you can use sortByOrder (renamed orderBy in v4.3.0):

var data = _.sortByOrder(array_of_objects, ['type','name'], [true, false]);

Since version 3.10.0 you can even use standard semantics for ordering (asc, desc):

var data = _.sortByOrder(array_of_objects, ['type','name'], ['asc', 'desc']);

In version 4 of lodash this method has been renamed orderBy:

var data = _.orderBy(array_of_objects, ['type','name'], ['asc', 'desc']);

for python 3.6, the following worked for me launch cmd.exe as administrator

pip install numpy-1.13.0+mkl-cp36-cp36m-win32 pip install scipy-0.19.1-cp36-cp36m-win32

Here are several methods:

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;height:100%;width:100%" height="100%" width="100%"></iframe>
</body>

AND ANOTHER ALTERNATIVE

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:100%;width:100%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" height="100%" width="100%"></iframe>
</body>

TO HIDE SCROLLING WITH 2 ALTERNATIVES AS SHOWN ABOVE

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;height:150%;width:150%" height="150%" width="150%"></iframe>
</body>

HACK WITH SECOND CODE

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="http://www.example.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:150%;width:150%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" height="150%" width="150%"></iframe>
</body>

To hide the scroll-bars of the iFrame, the parent is made "overflow:hidden" to hide scrollbars and the iFrame is made to go upto 150% width and height which forces the scroll-bars outside the page and since the body doesn't have scroll-bars one may not expect the iframe to be exceeding the bounds of the page. This hides the scrollbars of the iFrame with full width!

source: set iframe auto height

Using one of the above answers as a base, here's the Java/Android example:

protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    RectF bounds = new RectF(canvas.getClipBounds());
    float centerX = bounds.centerX();
    float centerY = bounds.centerY();

    float angleDeg = 90f;
    float radius = 20f

    float xPos = radius * (float)Math.cos(Math.toRadians(angleDeg)) + centerX;
    float yPos = radius * (float)Math.sin(Math.toRadians(angleDeg)) + centerY;

    //draw my point at xPos/yPos
}

A more powerful and flexible example can be found here: C# File Upload with form fields, cookies and headers

Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):

The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file

So I'd go for that one.

I had the same issue. Thanks for the answers above, I solved my issue. If there are people facing the same problem, here is two way to solve it:

• You can use {!! $news->body !!}
• You can use traditional php openning (It is not recommended) like: <?php echo $string ?>

I hope it helps.

My favorite visual merge tool is SourceGear DiffMerge

• It is free.
• Cross-platform (Windows, OS X, and Linux).
• Clean visual UI
• All diff features you'd expect (Diff, Merge, Folder Diff).
• Command line interface.
• Usable keyboard shortcuts.

I had the same problem, and my solving was to replace :

return redirect(url_for('index'))

with

return render_template('indexo.html',data=Todos.query.all())

in my POST and DELETE route.

The other solutions that use the GLOBAL keyword are a nightmare to maintain/readability (+namespace pollution and bugs) when the project gets bigger. I've seen this mistake many times and had the hassle of fixing it.

Use a JavaScript file and then use module exports.

Example:

File globals.js

var Globals = {
    'domain':'www.MrGlobal.com';
}

module.exports = Globals;

Then if you want to use these, use require.

var globals = require('globals'); // << globals.js path
globals.domain // << Domain.

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

Here is some example code to help you get started:

package com.acme;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class FileArrayProvider {

    public String[] readLines(String filename) throws IOException {
        FileReader fileReader = new FileReader(filename);
        BufferedReader bufferedReader = new BufferedReader(fileReader);
        List<String> lines = new ArrayList<String>();
        String line = null;
        while ((line = bufferedReader.readLine()) != null) {
            lines.add(line);
        }
        bufferedReader.close();
        return lines.toArray(new String[lines.size()]);
    }
}

And an example unit test:

package com.acme;

import java.io.IOException;

import org.junit.Test;

public class FileArrayProviderTest {

    @Test
    public void testFileArrayProvider() throws IOException {
        FileArrayProvider fap = new FileArrayProvider();
        String[] lines = fap
                .readLines("src/main/java/com/acme/FileArrayProvider.java");
        for (String line : lines) {
            System.out.println(line);
        }
    }
}

Hope this helps.

For a more flexible and lazy solution, you could match all properties of the objects. Most of the time, this should get you the behavior you want, and you can always be more specific when it doesn't. Here's a grep function that works based on this principle:

Function Select-ObjectPropertyValues {
    param(
    [Parameter(Mandatory=$true,Position=0)]
    [String]
    $Pattern,
    [Parameter(ValueFromPipeline)]
    $input)

    $input | Where-Object {($_.PSObject.Properties | Where-Object {$_.Value -match $Pattern} | Measure-Object).count -gt 0} | Write-Output
}

Try this for beginning with vowel

Oracle:

select distinct *field* from *tablename* where SUBSTR(*sort field*,1,1) IN('A','E','I','O','U') Order by *Sort Field*;

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

Use the below query to store the result in a CSV file

\copy (your query) to 'file path' csv header;

Example

\copy (select name,date_order from purchase_order) to '/home/ankit/Desktop/result.csv' cvs header;

Hope this helps you.

• First, str in Python is represented in Unicode.
• Second, UTF-8 is an encoding standard to encode Unicode string to bytes. There are many encoding standards out there (e.g. UTF-16, ASCII, SHIFT-JIS, etc.).

When the client sends data to your server and they are using UTF-8, they are sending a bunch of bytes not str.

You received a str because the "library" or "framework" that you are using, has implicitly converted some random bytes to str.

Under the hood, there is just a bunch of bytes. You just need ask the "library" to give you the request content in bytes and you will handle the decoding yourself (if library can't give you then it is trying to do black magic then you shouldn't use it).

I am in the same situation pointed out by malcook in his comment: unfortunately the answer by Thierry does not work with ggplot2 version 0.9.3.1.

png("figure_%d.png")
set.seed(2014)
library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100),
    x = rnorm(500, mean = rep(1:5, 100)),
    y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

Here it is the first figure:

and the second figure:

As we can see the colors do not stay fixed, for example E switches from magenta to blu.

As suggested by malcook in his comment and by hadley in his comment the code which uses limits works properly:

ggplot(subdata, aes(x = x, y = y, colour = fCategory)) +       
    geom_point() + 
    scale_colour_discrete(drop=TRUE,
        limits = levels(dataset$fCategory))

gives the following figure, which is correct:

sometimes you need to select some fields by FirstOrDefault() or singleOrDefault() you can use the below query:

List<ResultLine> result = Lines
    .GroupBy(l => l.ProductCode)
    .Select(cl => new Models.ResultLine
            {
                ProductName = cl.select(x=>x.Name).FirstOrDefault(),
                Quantity = cl.Count().ToString(),
                Price = cl.Sum(c => c.Price).ToString(),
            }).ToList();

In package.json set the following command (example for running on port 82)

"start": "set PORT=82 && ng serve --ec=true"

then npm start

With MongoDB Compass, you need to use the strict mode syntax, as such:

{ "text": { "$regex": "^Foo.*", "$options": "i" } }

(In MongoDB Compass, it's important that you use " instead of ')

Since /deep/, >>>, and ::ng-deep are all deprecated. The best approach is to use the following in your child component styling

:host-context(.theme-light) h2 {
  background-color: #eef;
}

This will look for the theme-light in any of the ancestors of your child component. See docs here: https://angular.io/guide/component-styles#host-context

CREATE TABLE table_temp_list_objects AS
SELECT o.owner, o.object_name FROM sys.all_objects o WHERE o.object_type ='TABLE';

Although I've used Eclipse for years, this "answer" is only conjecture (which I'm going to try tonight). If it gets down-voted out of existence, then obviously I'm wrong.

Oracle relies on CMake to generate a Visual Studio "Solution" for their MySQL Connector C source code. Within the Solution are "Projects" that can be compiled individually or collectively (by the Solution). Each Project has its own makefile, compiling its portion of the Solution with settings that are different than the other Projects.

Similarly, I'm hoping an Eclipse Workspace can hold my related makefile Projects (Eclipse), with a master Project whose dependencies compile the various unique-makefile Projects as pre-requesites to building its "Solution". (My folder structure would be as @Rafael describes).

So I'm hoping a good way to use Workspaces is to emulate Visual Studio's ability to combine dissimilar Projects into a Solution.

select * 
from (
      select 'T1' T, *
      from DB1.dbo.Table
      except
      select 'T2' T, *
      from DB2.dbo.Table
     ) as T
union all
select * 
from (
      select 'T2' T, *
      from DB2.dbo.Table
      except
      select 'T1' T, *
      from DB1.dbo.Table
     ) as T
ORDER BY 2,3,4, ..., 1  -- make T1 and T2 to be close in output 2,3,4 are UNIQUE KEY SEGMENTS

Test code:

declare @T1 table (ID int)
declare @T2 table (ID int)

insert into @T1 values(1),(2)
insert into @T2 values(2),(3)

select * 
from (
      select *
      from @T1
      except
      select *
      from @T2
     ) as T
union all
select * 
from (
      select *
      from @T2
      except
      select *
      from @T1
     ) as T

Result:

Note: It can take long time to compare big table, when developing "tuned" solution or refactorig, which will give same result as REFERERCE - it may be wise to chekc simple parameters first: like

select count(t.*) from (
   select count(*) c0, SUM(BINARY_CHECKSUM(*)%1000000) c1 FROM T_REF_TABLE 
   -- select 12345 c0, -214365454 c1 -- constant values FROM T_REF_TABLE 
   except 
   select count(*) , SUM(BINARY_CHECKSUM(*)%1000000) FROM T_WORK_COPY 
) t

When this is empty, you have probably things under controll, and may be you can modify when you fail you will see "constant values FROM T_REF" to isert to save even more time for next check!!!

If you are using a third party library called apache commons-lang, the following solution can be useful:

Use StringUtils class of apache commons-lang :

int i = 5;
StringUtils.leftPad(String.valueOf(i), 3, "0"); // --> "005"

As StringUtils.leftPad() is faster than String.format()

Reinstalling Compass worked for me.. It's a magic!

sudo gem install -n /usr/local/bin compass

In general, just use pg admin UI for doing db related activity.

If instead you are focusin more in automating database setup for your local development, or CI etc...

For example, you can use a simple combo like this.

(a) Create a dummy super user via jenkins with a command similar to this:

docker exec -t postgres11-instance1 createuser --username=postgres --superuser experiment001

this will create a super user called experiment001 in you postgres db.

(b) Give this user some password by running a NON-Interactive SQL command.

docker exec -t postgres11-instance1 psql -U experiment001 -d postgres -c "ALTER USER experiment001 WITH PASSWORD 'experiment001' "

Postgres is probably the best database out there for command line (non-interactive) tooling. Creating users, running SQL, making backup of database etc... In general it is all quite basic with postgres and it is overall quite trivial to integrate this into your development setup scripts or into automated CI configuration.

I had the same link errors, but from a test project which was referencing another dll. Found out that after adding _declspec(dllexport) in front of each function which was specified in the error message, the link was working well.

I am sharing our nodejs implementation of the solution as implemented by @Raymond Hettinger.

var crypto = require('crypto');
var s = 'she sells sea shells by the sea shore';
console.log(BigInt('0x' + crypto.createHash('sha1').update(s).digest('hex'))%(10n ** 8n));

Yield : will make thread to wait for the currently executing thread and the thread which has called yield() will attaches itself at the end of the thread execution. The thread which call yield() will be in Blocked state till its turn.

Sleep : will cause the thread to sleep in sleep mode for span of time mentioned in arguments.

Join : t1 and t2 are two threads , t2.join() is called then t1 enters into wait state until t2 completes execution. Then t1 will into runnable state then our specialist JVM thread scheduler will pick t1 based on criteria's.

An SQL JOIN clause is used to combine rows from two or more tables, based on a common field between them.

There are different types of joins available in SQL:

INNER JOIN: returns rows when there is a match in both tables.

LEFT JOIN: returns all rows from the left table, even if there are no matches in the right table.

RIGHT JOIN: returns all rows from the right table, even if there are no matches in the left table.

FULL JOIN: It combines the results of both left and right outer joins.

The joined table will contain all records from both the tables and fill in NULLs for missing matches on either side.

SELF JOIN: is used to join a table to itself as if the table were two tables, temporarily renaming at least one table in the SQL statement.

CARTESIAN JOIN: returns the Cartesian product of the sets of records from the two or more joined tables.

WE can take each first four joins in Details :

We have two tables with the following values.

TableA

id  firstName                  lastName
.......................................
1   arun                        prasanth

....................................................................

INNER JOIN

Note :it gives the intersection of the two tables, i.e. rows they have common in TableA and TableB

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
 INNER JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
 INNER JOIN TableB
    ON TableA.id = TableB.id2;

Result Will Be

firstName       lastName       age  Place
..............................................

LEFT JOIN

Note : will give all selected rows in TableA, plus any common selected rows in TableB.

Syntax

SELECT table1.column1, table2.column2...
  FROM table1
  LEFT JOIN table2
    ON table1.common_field = table2.common_field;

Apply it in our sample table :

SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
  FROM TableA
  LEFT JOIN TableB
    ON TableA.id = TableB.id2;

Result

firstName                   lastName                    age   Place

RIGHT JOIN

Note : will give all selected rows in TableB, plus any common selected rows in TableA.

Syntax

SELECT table1.column1, table2.column2...

Interesting Fact

For INNER joins the order doesn't matter

For (LEFT, RIGHT or FULL) OUTER joins,the order matter

Better to go check this Link it will give you interesting details about join order

Just my 2 cents, had:

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

at the end of body, wasn't working, had to add crossorigin="anonymous" and now it's working, Bootstrap version 3.3.6. ...

@RequestMapping(value="/") public String home(HttpServletRequest request){
    System.out.println("My Attribute :: "+request.getAttribute("YourAttributeName"));
    return "home"; 
}

book = load_workbook(xlsFilename)
writer = pd.ExcelWriter(self.xlsFilename)
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
df.to_excel(writer, sheet_name=sheetName, index=False)
writer.save()

Try delete:

models.User.query.delete()

From the docs: Returns the number of rows deleted, excluding any cascades.

The following should work for you:

[\n\r].*Object Name:\s*([^\n\r]*)

Working example

Your desired match will be in capture group 1.

[\n\r][ \t]*Object Name:[ \t]*([^\n\r]*)

Would be similar but not allow for things such as " blah Object Name: blah" and also make sure that not to capture the next line if there is no actual content after "Object Name:"

My solution:

html, body {
  min-height: 100%
}

body {
  padding-bottom: 88px;
}

footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 88px;
}

This has always worked well for me. It's not messy and very clean.

<a href="@Url.Action("Index", "Home")"><span>Text</span></a>

Since PopupWindow just adds a View to WindowManager you can use updateViewLayout (View view, ViewGroup.LayoutParams params) to update the LayoutParams of your PopupWindow's contentView after calling show..().

Setting the window flag FLAG_DIM_BEHIND will dimm everything behind the window. Use dimAmount to control the amount of dim (1.0 for completely opaque to 0.0 for no dim).

Keep in mind that if you set a background to your PopupWindow it will put your contentView into a container, which means you need to update it's parent.

With background:

PopupWindow popup = new PopupWindow(contentView, width, height);
popup.setBackgroundDrawable(background);
popup.showAsDropDown(anchor);

View container = (View) popup.getContentView().getParent();
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) container.getLayoutParams();
// add flag
p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
wm.updateViewLayout(container, p);

Without background:

PopupWindow popup = new PopupWindow(contentView, width, height);
popup.setBackgroundDrawable(null);
popup.showAsDropDown(anchor);

WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) contentView.getLayoutParams();
// add flag
p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.3f;
wm.updateViewLayout(contentView, p);

Marshmallow Update:

On M PopupWindow wraps the contentView inside a FrameLayout called mDecorView. If you dig into the PopupWindow source you will find something like createDecorView(View contentView).The main purpose of mDecorView is to handle event dispatch and content transitions, which are new to M. This means we need to add one more .getParent() to access the container.

With background that would require a change to something like:

View container = (View) popup.getContentView().getParent().getParent();

Better alternative for API 18+

A less hacky solution using ViewGroupOverlay:

1) Get a hold of the desired root layout

ViewGroup root = (ViewGroup) getWindow().getDecorView().getRootView();

2) Call applyDim(root, 0.5f); or clearDim()

public static void applyDim(@NonNull ViewGroup parent, float dimAmount){
    Drawable dim = new ColorDrawable(Color.BLACK);
    dim.setBounds(0, 0, parent.getWidth(), parent.getHeight());
    dim.setAlpha((int) (255 * dimAmount));

    ViewGroupOverlay overlay = parent.getOverlay();
    overlay.add(dim);
}

public static void clearDim(@NonNull ViewGroup parent) {
    ViewGroupOverlay overlay = parent.getOverlay();
    overlay.clear();
}

Your question may mean two different things:

1.) Open a web page with a browser.

#include <windows.h>
#include <shellapi.h>
...
ShellExecute(0, 0, L"http://www.google.com", 0, 0 , SW_SHOW );

This should work, it opens the file with the associated program. Should open the browser, which is usually the default web browser.

2.) Get the code of a webpage and you will render it yourself or do some other thing. For this I recommend to read this or/and this.

I hope it's at least a little helpful.

EDIT: Did not notice, what you are asking for UNIX, this only work on Windows.

Use:

def max_indices(arr, k):
    '''
    Returns the indices of the k first largest elements of arr
    (in descending order in values)
    '''
    assert k <= arr.size, 'k should be smaller or equal to the array size'
    arr_ = arr.astype(float)  # make a copy of arr
    max_idxs = []
    for _ in range(k):
        max_element = np.max(arr_)
        if np.isinf(max_element):
            break
        else:
            idx = np.where(arr_ == max_element)
        max_idxs.append(idx)
        arr_[idx] = -np.inf
    return max_idxs

It also works with 2D arrays. For example,

In [0]: A = np.array([[ 0.51845014,  0.72528114],
                     [ 0.88421561,  0.18798661],
                     [ 0.89832036,  0.19448609],
                     [ 0.89832036,  0.19448609]])
In [1]: max_indices(A, 8)
Out[1]:
    [(array([2, 3], dtype=int64), array([0, 0], dtype=int64)),
     (array([1], dtype=int64), array([0], dtype=int64)),
     (array([0], dtype=int64), array([1], dtype=int64)),
     (array([0], dtype=int64), array([0], dtype=int64)),
     (array([2, 3], dtype=int64), array([1, 1], dtype=int64)),
     (array([1], dtype=int64), array([1], dtype=int64))]

In [2]: A[max_indices(A, 8)[0]][0]
Out[2]: array([ 0.89832036])

The jQuery Audit plugin plugin should let you do this through the normal Chrome Dev Tools. It's not perfect, but it should let you see the actual handler bound to the element/event and not just the generic jQuery handler.

You can't alter the existing columns for identity.

You have 2 options,

1. Create a new table with identity & drop the existing table

2. Create a new column with identity & drop the existing column

Approach 1. (New table) Here you can retain the existing data values on the newly created identity column. Note that you will lose all data if 'if not exists' is not satisfied, so make sure you put the condition on the drop as well!

CREATE TABLE dbo.Tmp_Names
    (
      Id int NOT NULL
             IDENTITY(1, 1),
      Name varchar(50) NULL
    )
ON  [PRIMARY]
go

SET IDENTITY_INSERT dbo.Tmp_Names ON
go

IF EXISTS ( SELECT  *
            FROM    dbo.Names ) 
    INSERT  INTO dbo.Tmp_Names ( Id, Name )
            SELECT  Id,
                    Name
            FROM    dbo.Names TABLOCKX
go

SET IDENTITY_INSERT dbo.Tmp_Names OFF
go

DROP TABLE dbo.Names
go

Exec sp_rename 'Tmp_Names', 'Names'

Approach 2 (New column) You can’t retain the existing data values on the newly created identity column, The identity column will hold the sequence of number.

Alter Table Names
Add Id_new Int Identity(1, 1)
Go

Alter Table Names Drop Column ID
Go

Exec sp_rename 'Names.Id_new', 'ID', 'Column'

See the following Microsoft SQL Server Forum post for more details:

How to alter column to identity(1,1)

You get one for free, called ROWID. This is in every SQLite table whether you ask for it or not.

If you include a column of type INTEGER PRIMARY KEY, that column points at (is an alias for) the automatic ROWID column.

ROWID (by whatever name you call it) is assigned a value whenever you INSERT a row, as you would expect. If you explicitly assign a non-NULL value on INSERT, it will get that specified value instead of the auto-increment. If you explicitly assign a value of NULL on INSERT, it will get the next auto-increment value.

Also, you should try to avoid:

 INSERT INTO people VALUES ("John", "Smith");

and use

 INSERT INTO people (first_name, last_name) VALUES ("John", "Smith");

instead. The first version is very fragile — if you ever add, move, or delete columns in your table definition the INSERT will either fail or produce incorrect data (with the values in the wrong columns).

If you are trying to "Submit and Reset" the the "form" with one Button click, Try this!

Here I have used jQuery function, it can be done by simple JavaScript also...

        <form id="form_data">
           <input type="anything"  name="anything" />
           <input type="anything"  name="anything" />

             <!-- Save and Reset button -->
           <button type="button" id="btn_submit">Save</button>
           <button type="reset" id="btn_reset" style="display: none;"></button>
        </form>

<script type="text/javascript">
$(function(){
    $('#btn_submit').click(function(){
        // Do what ever you want
       $('#btn_reset').click();  // Clicking reset button
    });
});
</script>

Use the onclick="this.select()" attribute for the input tag.

I think you need the time gap between job_start & job_end.

Try this...

select SUBSTRING(CONVERT(VARCHAR(20),(job_end - job_start),120),12,8) from tableA

I ended up with this.

if (isset($_POST['remove'])) {
    $key=array_search($_GET['name'],$_SESSION['name']);
    if($key!==false)
    unset($_SESSION['name'][$key]);
    $_SESSION["name"] = array_values($_SESSION["name"]);
} 

Since $_SESSION['name'] is an array, you need to find the array key that points at the name value you're interested in. The last line rearranges the index of the array for the next use.

Are you sure you are using correct SMTP server address?

Both smtp.google.com and smtp.gmail.com work, but SSL certificate is issued to the second one.

This is one way to do it (in Python 3.x):

escaped = a_string.translate(str.maketrans({"-":  r"\-",
                                          "]":  r"\]",
                                          "\\": r"\\",
                                          "^":  r"\^",
                                          "$":  r"\$",
                                          "*":  r"\*",
                                          ".":  r"\."}))

For reference, for escaping strings to use in regex:

import re
escaped = re.escape(a_string)

Try this:

@Html.DropDownList(
    "country", 
    new[] {
        new SelectListItem() { Value = "IN", Text = "India" },
        new SelectListItem() { Value = "US", Text = "United States" }
    }, 
    "Country",
    new { @class = "form-control",@selected = Model.Country}
)

echo $line | tr " " "\n"

gives the output similar to those of most of the answers above; without using loops.


In your case, you also mention ll=<...output...>,
so, (given that I don't know much python and assuming you need to assign output to a variable),

ll=`echo $line | tr " " "\n"`

should suffice (remember to echo "$ll" instead of echo $ll)

Setting my RequestOperationManager Response Serializer to HTTPResponseSerializer fixed the issue.

Objective-C

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

Swift

manager.responseSerializer = AFHTTPResponseSerializer()

Making this change means I don't need to add acceptableContentTypes to every request I make.

Many to Many (n:m) One to Many (1:n)

Try this:

if(Math.floor(id) == id && $.isNumeric(id)) 
  alert('yes its an int!');

$.isNumeric(id) checks whether it's numeric or not
Math.floor(id) == id will then determine if it's really in integer value and not a float. If it's a float parsing it to int will give a different result than the original value. If it's int both will be the same.

While Loop is an obsolete structure, I would recommend you to replace "While loop" to "Do While..loop", and you will able to use Exit clause.

check = 0 

Do while not rs.EOF 
   if rs("reg_code") = rcode then 
      check = 1 
      Response.Write ("Found") 
      Exit do
   else 
      rs.MoveNext 
    end if 
Loop 

if check = 0 then 
   Response.Write "Not Found" 
end if}

static String  string_swap(String str, int x, int y)
{

    if( x < 0 || x >= str.length() || y < 0 || y >= str.length())
    return "Invalid index";

    char arr[] = str.toCharArray();
    char tmp = arr[x];
    arr[x] = arr[y];
    arr[y] = tmp;

    return new String(arr);
}

Builder Pattern and Factory pattern, both seem pretty similar to naked eyes because they both create objects for you.

But you need to look closer

This real-life example will make the difference between the two more clear.

Suppose, you went to a fast food restaurant and you ordered Food.

1) What Food?

Pizza

2) What toppings?

Capsicum, Tomato, BBQ chicken, NO PINEAPPLE

So different kinds of foods are made by Factory pattern but the different variants(flavors) of a particular food are made by Builder pattern.

Different kinds of foods

Pizza, Burger, Pasta

Variants of Pizza

Only Cheese, Cheese+Tomato+Capsicum, Cheese+Tomato etc.

Code sample

You can see the sample code implementation of both patterns here
Builder Pattern
Factory Pattern

I think just these two lines are enough.

set(CMAKE_CXX_STANDARD 11)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

i have a pretty answer try this code ;)

<div id="DivID">
</div>

$("#DivID").scrollview({ direction: 'y' });
$("#DivID > .ui-scrollbar").addClass("ui-scrollbar-visible");

What you're trying to accomplish is called Reverse DNS lookup.

socket.gethostbyaddr("IP") 
# => (hostname, alias-list, IP)

http://docs.python.org/library/socket.html?highlight=gethostbyaddr#socket.gethostbyaddr

However, for the timeout part I have read about people running into problems with this. I would check out PyDNS or this solution for more advanced treatment.

here is my solution (compiled CSS):

.row.row-xs-eq {
  display: table;
  table-layout: fixed;
  margin: 0;
}

.row.row-xs-eq::before {
  content: none;
}

.row.row-xs-eq::after {
  content: none;
}

.row.row-xs-eq > [class^='col-'] {
  display: table-cell;
  float: none;
  padding: 0;
}

@media (min-width: 768px) {
  .row.row-sm-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-sm-eq::before {
    content: none;
  }

  .row.row-sm-eq::after {
    content: none;
  }

  .row.row-sm-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

@media (min-width: 992px) {
  .row.row-md-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-md-eq::before {
    content: none;
  }

  .row.row-md-eq::after {
    content: none;
  }

  .row.row-md-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

@media (min-width: 1200px) {
  .row.row-lg-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-lg-eq::before {
    content: none;
  }

  .row.row-lg-eq::after {
    content: none;
  }

  .row.row-lg-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

So your code would look like:

<div class="row row-sm-eq">
  <!-- your old cols definition here -->
</div>

Basically this is the same system you use with .col-* classes with that difference you need to apply .row-* classes to the row itself.

With .row-sm-eq columns will be stacked on XS screens. If you don't need them to be stacked on any screens you can use .row-xs-eq.

The SASS version that we do actually use:

.row {
  @mixin row-eq-height {
    display: table;
    table-layout: fixed;
    margin: 0;

    &::before {
      content: none;
    }

    &::after {
      content: none;
    }

    > [class^='col-'] {
      display: table-cell;
      float: none;
      padding: 0;
    }
  }

  &.row-xs-eq {
    @include row-eq-height;
  }

  @media (min-width: $screen-sm-min) {
    &.row-sm-eq {
      @include row-eq-height;
    }
  }

  @media (min-width: $screen-md-min) {
    &.row-md-eq {
      @include row-eq-height;
    }
  }

  @media (min-width: $screen-lg-min) {
    &.row-lg-eq {
      @include row-eq-height;
    }
  }
}

Live demo

Note: mixing .col-xs-12 and .col-xs-6 inside a single row would not work properly.

UPDATE:

Since I was lazy, and didn't fully implement my solution, I searched around and found BlockComment for Xcode, a recently released plugin (June 2017). Don't bother with my solution, this plugin works beautifully, and I highly recommend it.

ORIGINAL ANSWER:

None of the above worked for me on Xcode 7 and 8, so I:

1. Created Automator service using AppleScript
2. Make sure "Output replaces selected text" is checked

3. Enter the following code:

   on run {input, parameters}
   return "/*\n" & (input as string) & "*/"
   end run
   

Now you can access that service through Xcode - Services menu, or by right clicking on the selected block of code you wish to comment, or giving it a shortcut under System Preferences.

With : i << 2

const data = context.getImageData(x, y, width, height).data;
const pixels = [];

for (let i = 0, dx = 0; dx < data.length; i++, dx = i << 2) {
    if (data[dx+3] <= 8)
        console.log("transparent x= " + i);
}

Using docker links, you can link the upstream container to the nginx container. An added feature is that docker manages the host file, which means you'll be able to refer to the linked container using a name rather than the potentially random ip.

You can't. CSS does not support "events". Dare I ask what you need it for? Check out this post here on SO. I can't think of a reason why you would want to hook up an event to a style change. I'm assuming here that the style change is triggered somwhere else by a piece of javascript. Why not add extra logic there?

Use ampersand to specify the parent selector.

SCSS syntax:

p {
    margin: 2em auto;

    > a {
        color: red;
    }

    &:before {
        content: "";
    }

    &:after {
        content: "* * *";
    }
}

If you create a web based application, the better solution is to check the directory exists or not then create the file if not exist. If exists, recreate again.

    private File createFile(String path, String fileName) throws IOException {
       ClassLoader classLoader = getClass().getClassLoader();
       File file = new File(classLoader.getResource(".").getFile() + path + fileName);

       // Lets create the directory
       try {
          file.getParentFile().mkdir();
       } catch (Exception err){
           System.out.println("ERROR (Directory Create)" + err.getMessage());
       }

       // Lets create the file if we have credential
       try {
           file.createNewFile();
       } catch (Exception err){
           System.out.println("ERROR (File Create)" + err.getMessage());
       }
       return  file;
   }

tk-devel also needs to be installed in my case

yum install -y tkinter tk-devel

install these and rebuild python

I had this issue for days looking for answers. My error log was similar to this npm just won't install node sass The only problem was the node version. Maybe it can help some of you.

I downgraded my Node.js from 9.3.0 to 6.12.2 and run:

npm update

I wanted to achieve on-boot container startup on Windows.

Therefore, I just created a scheduled Task which launches on system boot. That task simply starts "Docker for Windows.exe" (or whatever is the name of your docker executable).

Then, all containers with a restart policy of "always" will start up.

You've not shown how you're creating the string 2016-01-12T23:00:00.000Z, but I assume via .format().

Anyway, .set() is using your local time zone, but the Z in the time string indicates zero time, otherwise known as UTC.

https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators

So I assume your local timezone is 23 hours from UTC?

saikumar's answer showed how to load the time in as UTC, but the other option is to use a .format() call that outputs using your local timezone, rather than UTC.

http://momentjs.com/docs/#/get-set/
http://momentjs.com/docs/#/displaying/format/

executing a count(*) query on big data is expensive. i think using "SELECT * FROM table ORDER BY id DESC LIMIT n" where n is your number of rows per page is better and lighter

I propose to use

SET time_zone = 'proper timezone';

being done once right after connect to database. and after this all timestamps will be converted automatically when selecting them.

In the Drupal or Wordpress CMS (and likely others), if you are trying to make some custom php code appear not to exist (unless some condition is met), the following works well by making the CMS's 404 handler take over:

<?php
  if(condition){
    do stuff;
  } else {
    include('index.php');
  }
?>

Python 3.6 f-strings allows us to add leading zeros easily:

number = 5
print(f' now we have leading zeros in {number:02d}')

Have a look at this good post about this feature.

Your web.config file should have this structure:

<configuration>
    <connectionStrings>
        <add name="MyConnectionString" connectionString="..." />
    </connectionStrings>
</configuration>

Then, to create a SQL connection using the connection string named MyConnectionString:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);

If you'd prefer to keep your connection strings in the AppSettings section of your configuration file, it would look like this:

<configuration>
    <appSettings>
        <add key="MyConnectionString" value="..." />
    </appSettings>
</configuration>

And then your SqlConnection constructor would look like this:

SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyConnectionString"]);

i was having some issues with windowhandle and tried this one. this one works good for me.

String parentWindowHandler = driver.getWindowHandle(); 
String subWindowHandler = null;

Set<String> handles = driver.getWindowHandles();
Iterator<String> iterator = handles.iterator();
while (iterator.hasNext()){
    subWindowHandler = iterator.next();
    driver.switchTo().window(subWindowHandler);

    System.out.println(subWindowHandler);
}


driver.switchTo().window(parentWindowHandler); 

I'm clearly not adding anything fundamentally new, but added this answer before I was up to commenting status, plus the code regions make things more clear -- anyway, specifically to answer @Nemo's question from Omnifarious's answer:

I happened to be thinking about checksums a bit (came here looking for suggestions on block sizes, specifically), and have found that this method may be faster than you'd expect. Taking the fastest (but pretty typical) timeit.timeit or /usr/bin/time result from each of several methods of checksumming a file of approx. 11MB:

$ ./sum_methods.py
crc32_mmap(filename) 0.0241742134094
crc32_read(filename) 0.0219960212708
subprocess.check_output(['cksum', filename]) 0.0553209781647
md5sum_mmap(filename) 0.0286180973053
md5sum_read(filename) 0.0311000347137
subprocess.check_output(['md5sum', filename]) 0.0332629680634
$ time md5sum /tmp/test.data.300k
d3fe3d5d4c2460b5daacc30c6efbc77f  /tmp/test.data.300k

real    0m0.043s
user    0m0.032s
sys     0m0.010s
$ stat -c '%s' /tmp/test.data.300k
11890400

So, looks like both Python and /usr/bin/md5sum take about 30ms for an 11MB file. The relevant md5sum function (md5sum_read in the above listing) is pretty similar to Omnifarious's:

import hashlib
def md5sum(filename, blocksize=65536):
    hash = hashlib.md5()
    with open(filename, "rb") as f:
        for block in iter(lambda: f.read(blocksize), b""):
            hash.update(block)
    return hash.hexdigest()

Granted, these are from single runs (the mmap ones are always a smidge faster when at least a few dozen runs are made), and mine's usually got an extra f.read(blocksize) after the buffer is exhausted, but it's reasonably repeatable and shows that md5sum on the command line is not necessarily faster than a Python implementation...

EDIT: Sorry for the long delay, haven't looked at this in some time, but to answer @EdRandall's question, I'll write down an Adler32 implementation. However, I haven't run the benchmarks for it. It's basically the same as the CRC32 would have been: instead of the init, update, and digest calls, everything is a zlib.adler32() call:

import zlib
def adler32sum(filename, blocksize=65536):
    checksum = zlib.adler32("")
    with open(filename, "rb") as f:
        for block in iter(lambda: f.read(blocksize), b""):
            checksum = zlib.adler32(block, checksum)
    return checksum & 0xffffffff

Note that this must start off with the empty string, as Adler sums do indeed differ when starting from zero versus their sum for "", which is 1 -- CRC can start with 0 instead. The AND-ing is needed to make it a 32-bit unsigned integer, which ensures it returns the same value across Python versions.

Best solution: Goto jboss-as-7.1.1.Final\standalone\deployments folder and delete all existing files....

Run again your problem will be solved

Without any additional packages:

true_Y = c(1,1,1,1,2,1,2,1,2,2)
probs = c(1,0.999,0.999,0.973,0.568,0.421,0.382,0.377,0.146,0.11)

getROC_AUC = function(probs, true_Y){
    probsSort = sort(probs, decreasing = TRUE, index.return = TRUE)
    val = unlist(probsSort$x)
    idx = unlist(probsSort$ix)  

    roc_y = true_Y[idx];
    stack_x = cumsum(roc_y == 2)/sum(roc_y == 2)
    stack_y = cumsum(roc_y == 1)/sum(roc_y == 1)    

    auc = sum((stack_x[2:length(roc_y)]-stack_x[1:length(roc_y)-1])*stack_y[2:length(roc_y)])
    return(list(stack_x=stack_x, stack_y=stack_y, auc=auc))
}

aList = getROC_AUC(probs, true_Y) 

stack_x = unlist(aList$stack_x)
stack_y = unlist(aList$stack_y)
auc = unlist(aList$auc)

plot(stack_x, stack_y, type = "l", col = "blue", xlab = "False Positive Rate", ylab = "True Positive Rate", main = "ROC")
axis(1, seq(0.0,1.0,0.1))
axis(2, seq(0.0,1.0,0.1))
abline(h=seq(0.0,1.0,0.1), v=seq(0.0,1.0,0.1), col="gray", lty=3)
legend(0.7, 0.3, sprintf("%3.3f",auc), lty=c(1,1), lwd=c(2.5,2.5), col="blue", title = "AUC")

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

In HTML:

<a href="index.php?link=home" name="home">home</a>

Then in PHP:

if(isset($_GET['link'])){$_SESSION['link'] = $_GET['link'];}

With a few CSS overrides, I find the accordion / collapse plugin works well as a sidebar vertical menu. Here's a small sample of some overrides I use for a menu on a white background. The accordion is placed within a section container:

.accordion-group
{
    margin-bottom: 1px;
    -webkit-border-radius: 0px;
    -moz-border-radius: 0px;
    border-radius: 0px;
    border-bottom: 1px solid #E5E5E5;
    border-top: none;
    border-left: none;
    border-right: none;
}

.accordion-heading:hover
{
    background-color: #FFFAD9;
}

When we put together a react-redux application we should expect to see a structure where at the top we have the Provider tag which has an instance of a redux store.

That Provider tag then renders your parent component, lets call it the App component which in turn renders every other component inside the application.

Here is the key part, when we wrap a component with the connect() function, that connect() function expects to see some parent component within the hierarchy that has the Provider tag.

So the instance you put the connect() function in there, it will look up the hierarchy and try to find the Provider.

Thats what you want to have happen, but in your test environment that flow is breaking down.

Why?

Why?

When we go back over to the assumed sportsDatabase test file, you must be the sportsDatabase component by itself and then trying to render that component by itself in isolation.

So essentially what you are doing inside that test file is just taking that component and just throwing it off in the wild and it has no ties to any Provider or store above it and thats why you are seeing this message.

There is not store or Provider tag in the context or prop of that component and so the component throws an error because it want to see a Provider tag or store in its parent hierarchy.

So that’s what that error means.

• getattr(x, 'y') is equivalent to x.y
• setattr(x, 'y', v) is equivalent to x.y = v
• delattr(x, 'y') is equivalent to del x.y

Probably the exact details of em.flush() are implementation-dependent. In general anyway, JPA providers like Hibernate can cache the SQL instructions they are supposed to send to the database, often until you actually commit the transaction. For example, you call em.persist(), Hibernate remembers it has to make a database INSERT, but does not actually execute the instruction until you commit the transaction. Afaik, this is mainly done for performance reasons.

In some cases anyway you want the SQL instructions to be executed immediately; generally when you need the result of some side effects, like an autogenerated key, or a database trigger.

What em.flush() does is to empty the internal SQL instructions cache, and execute it immediately to the database.

Bottom line: no harm is done, only you could have a (minor) performance hit since you are overriding the JPA provider decisions as regards the best timing to send SQL instructions to the database.

Attention: this is an extremely rough and oversimplified sketch, assuming the simplest possible HTTP request (no HTTPS, no HTTP2, no extras), simplest possible DNS, no proxies, single-stack IPv4, one HTTP request only, a simple HTTP server on the other end, and no problems in any step. This is, for most contemporary intents and purposes, an unrealistic scenario; all of these are far more complex in actual use, and the tech stack has become an order of magnitude more complicated since this was written. With this in mind, the following timeline is still somewhat valid:

1. browser checks cache; if requested object is in cache and is fresh, skip to #9
2. browser asks OS for server's IP address
3. OS makes a DNS lookup and replies the IP address to the browser
4. browser opens a TCP connection to server (this step is much more complex with HTTPS)
5. browser sends the HTTP request through TCP connection
6. browser receives HTTP response and may close the TCP connection, or reuse it for another request
7. browser checks if the response is a redirect or a conditional response (3xx result status codes), authorization request (401), error (4xx and 5xx), etc.; these are handled differently from normal responses (2xx)
8. if cacheable, response is stored in cache
9. browser decodes response (e.g. if it's gzipped)
10. browser determines what to do with response (e.g. is it a HTML page, is it an image, is it a sound clip?)
11. browser renders response, or offers a download dialog for unrecognized types

Again, discussion of each of these points have filled countless pages; take this only as a summary, abridged for the sake of clarity. Also, there are many other things happening in parallel to this (processing typed-in address, speculative prefetching, adding page to browser history, displaying progress to user, notifying plugins and extensions, rendering the page while it's downloading, pipelining, connection tracking for keep-alive, cookie management, checking for malicious content etc.) - and the whole operation gets an order of magnitude more complex with HTTPS (certificates and ciphers and pinning, oh my!).

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

public IHttpActionResult Post(Task task)

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

public IHttpActionResult Post(DTOTask task)

The simplest answer, assuming you don't mind the vagaries and variations in format between different platforms, is the standard %p notation.

The C99 standard (ISO/IEC 9899:1999) says in §7.19.6.1 ¶8:

p The argument shall be a pointer to void. The value of the pointer is converted to a sequence of printing characters, in an implementation-defined manner.

(In C11 — ISO/IEC 9899:2011 — the information is in §7.21.6.1 ¶8.)

On some platforms, that will include a leading 0x and on others it won't, and the letters could be in lower-case or upper-case, and the C standard doesn't even define that it shall be hexadecimal output though I know of no implementation where it is not.

It is somewhat open to debate whether you should explicitly convert the pointers with a (void *) cast. It is being explicit, which is usually good (so it is what I do), and the standard says 'the argument shall be a pointer to void'. On most machines, you would get away with omitting an explicit cast. However, it would matter on a machine where the bit representation of a char * address for a given memory location is different from the 'anything else pointer' address for the same memory location. This would be a word-addressed, instead of byte-addressed, machine. Such machines are not common (probably not available) these days, but the first machine I worked on after university was one such (ICL Perq).

If you aren't happy with the implementation-defined behaviour of %p, then use C99 <inttypes.h> and uintptr_t instead:

printf("0x%" PRIXPTR "\n", (uintptr_t)your_pointer);

This allows you to fine-tune the representation to suit yourself. I chose to have the hex digits in upper-case so that the number is uniformly the same height and the characteristic dip at the start of 0xA1B2CDEF appears thus, not like 0xa1b2cdef which dips up and down along the number too. Your choice though, within very broad limits. The (uintptr_t) cast is unambiguously recommended by GCC when it can read the format string at compile time. I think it is correct to request the cast, though I'm sure there are some who would ignore the warning and get away with it most of the time.

Kerrek asks in the comments:

I'm a bit confused about standard promotions and variadic arguments. Do all pointers get standard-promoted to void*? Otherwise, if int* were, say, two bytes, and void* were 4 bytes, then it'd clearly be an error to read four bytes from the argument, non?

I was under the illusion that the C standard says that all object pointers must be the same size, so void * and int * cannot be different sizes. However, what I think is the relevant section of the C99 standard is not so emphatic (though I don't know of an implementation where what I suggested is true is actually false):

§6.2.5 Types

¶26 A pointer to void shall have the same representation and alignment requirements as a pointer to a character type.³⁹⁾ Similarly, pointers to qualified or unqualified versions of compatible types shall have the same representation and alignment requirements. All pointers to structure types shall have the same representation and alignment requirements as each other. All pointers to union types shall have the same representation and alignment requirements as each other. Pointers to other types need not have the same representation or alignment requirements.

³⁹⁾ The same representation and alignment requirements are meant to imply interchangeability as arguments to functions, return values from functions, and members of unions.

(C11 says exactly the same in the section §6.2.5, ¶28, and footnote 48.)

So, all pointers to structures must be the same size as each other, and must share the same alignment requirements, even though the structures the pointers point at may have different alignment requirements. Similarly for unions. Character pointers and void pointers must have the same size and alignment requirements. Pointers to variations on int (meaning unsigned int and signed int) must have the same size and alignment requirements as each other; similarly for other types. But the C standard doesn't formally say that sizeof(int *) == sizeof(void *). Oh well, SO is good for making you inspect your assumptions.

The C standard definitively does not require function pointers to be the same size as object pointers. That was necessary not to break the different memory models on DOS-like systems. There you could have 16-bit data pointers but 32-bit function pointers, or vice versa. This is why the C standard does not mandate that function pointers can be converted to object pointers and vice versa.

Fortunately (for programmers targetting POSIX), POSIX steps into the breach and does mandate that function pointers and data pointers are the same size:

§2.12.3 Pointer Types

All function pointer types shall have the same representation as the type pointer to void. Conversion of a function pointer to void * shall not alter the representation. A void * value resulting from such a conversion can be converted back to the original function pointer type, using an explicit cast, without loss of information.

Note: The ISO C standard does not require this, but it is required for POSIX conformance.

So, it does seem that explicit casts to void * are strongly advisable for maximum reliability in the code when passing a pointer to a variadic function such as printf(). On POSIX systems, it is safe to cast a function pointer to a void pointer for printing. On other systems, it is not necessarily safe to do that, nor is it necessarily safe to pass pointers other than void * without a cast.

Some of Methods mentioned above ignores if there are any integers and float with values 0 & 0.0

If someone wants to avoid the above can use below code(removes empty strings and None values from nested dictionary and nested list):

def remove_empty_from_dict(d):
    if type(d) is dict:
        _temp = {}
        for k,v in d.items():
            if v == None or v == "":
                pass
            elif type(v) is int or type(v) is float:
                _temp[k] = remove_empty_from_dict(v)
            elif (v or remove_empty_from_dict(v)):
                _temp[k] = remove_empty_from_dict(v)
        return _temp
    elif type(d) is list:
        return [remove_empty_from_dict(v) for v in d if( (str(v).strip() or str(remove_empty_from_dict(v)).strip()) and (v != None or remove_empty_from_dict(v) != None))]
    else:
        return d

#warpcontainer  {width:800px; height:auto; border: 1px solid #000; float:left; }
#warpcontainer2 {width:260px; height:auto; border: 1px solid #000; float:left; clear:both; margin-top:10px }

You can use following formulas.

For Excel 2007 or later:

=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")

For Excel 2003:

=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))

Note, that

• I'm using List!A:C in VLOOKUP and returns value from column ? 3
• I'm using 4th argument for VLOOKUP equals to FALSE, in that case VLOOKUP will only find an exact match, and the values in the first column of List!A:C do not need to be sorted (opposite to case when you're using TRUE).

You could subclass ArrayList, and call Collections.sort(this) after any element is added - you would need to override two versions of add, and two of addAll, to do this.

Performance would not be as good as a smarter implementation which inserted elements in the right place, but it would do the job. If addition to the list is rare, the cost amortised over all operations on the list should be low.

Pass float to sleep, like sleep 0.1

Here's how I find valid 10-digit US phone numbers. At this point I'm assuming the user wants my content so the numbers themselves are trusted. I'm using in an app that ultimately sends an SMS message so I just want the raw numbers no matter what. Formatting can always be added later

//eliminate every char except 0-9
$justNums = preg_replace("/[^0-9]/", '', $string);

//eliminate leading 1 if its there
if (strlen($justNums) == 11) $justNums = preg_replace("/^1/", '',$justNums);

//if we have 10 digits left, it's probably valid.
if (strlen($justNums) == 10) $isPhoneNum = true;

Edit: I ended up having to port this to Java, if anyone's interested. It runs on every keystroke so I tried to keep it fairly light:

boolean isPhoneNum = false;
if (str.length() >= 10 && str.length() <= 14 ) { 
  //14: (###) ###-####
  //eliminate every char except 0-9
  str = str.replaceAll("[^0-9]", "");

  //remove leading 1 if it's there
  if (str.length() == 11) str = str.replaceAll("^1", "");

  isPhoneNum = str.length() == 10;
}
Log.d("ISPHONENUM", String.valueOf(isPhoneNum));

Because of double print function. I suggest you to use return instead of print inside the function definition.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

PHP is evaluated at the server; javascript is evaluated at the client/browser, thus you can't call a PHP function from javascript directly. But you can issue an HTTP request to the server that will activate a PHP function, with AJAX.

you can use this.finish() if you want to close current activity.

this.finish()

You can solve this fully in the html:

<div>
  <input ng-model=collapse type=checkbox>Title
  <div ng-show=collapse>
     Only shown when checkbox is clicked
  </div>
</div>

This also works well with ng-repeat since it will create a local scope for each member.

<table>
  <tbody ng-repeat='m in members'>
    <tr>
       <td><input type=checkbox ng-model=collapse></td>
       <td>{{m.title}}</td>
    </tr>
    <tr ng-show=collapse>
      <td> </td>
      <td>{{ m.content }}</td>
    </tr>
  </tbody>
</table>

Be aware that even though a repeat has its own scope, initially it will inherit the value from collapse from super scopes. This allows you to set the initial value in one place but it can be surprising.

You can of course restyle the checkbox. See http://jsfiddle.net/azD5m/5/

Updated fiddle: http://jsfiddle.net/azD5m/374/ Original fiddle used closing </input> tags to add the HTML text label instead of using <label> tags.

This is almost like the other answer but you don't need a scatter plot at all, you can simply specify a scatter-plot-like format (fmt-parameter) for errorbar:

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [1, 4, 9, 16]
e = [0.5, 1., 1.5, 2.]
plt.errorbar(x, y, yerr=e, fmt='o')
plt.show()

Result:

A list of the avaiable fmt parameters can be found for example in the plot documentation:

character   description
'-'     solid line style
'--'    dashed line style
'-.'    dash-dot line style
':'     dotted line style
'.'     point marker
','     pixel marker
'o'     circle marker
'v'     triangle_down marker
'^'     triangle_up marker
'<'     triangle_left marker
'>'     triangle_right marker
'1'     tri_down marker
'2'     tri_up marker
'3'     tri_left marker
'4'     tri_right marker
's'     square marker
'p'     pentagon marker
'*'     star marker
'h'     hexagon1 marker
'H'     hexagon2 marker
'+'     plus marker
'x'     x marker
'D'     diamond marker
'd'     thin_diamond marker
'|'     vline marker

You can use boolean indexing:

df = pd.DataFrame({'Sales':[10,20,30,40,50], 'A':[3,4,7,6,1]})
print (df)
   A  Sales
0  3     10
1  4     20
2  7     30
3  6     40
4  1     50

s = 30

df1 = df[df['Sales'] >= s]
print (df1)
   A  Sales
2  7     30
3  6     40
4  1     50

df2 = df[df['Sales'] < s]
print (df2)
   A  Sales
0  3     10
1  4     20

It's also possible to invert mask by ~:

mask = df['Sales'] >= s
df1 = df[mask]
df2 = df[~mask]
print (df1)
   A  Sales
2  7     30
3  6     40
4  1     50

print (df2)
   A  Sales
0  3     10
1  4     20

print (mask)
0    False
1    False
2     True
3     True
4     True
Name: Sales, dtype: bool

print (~mask)
0     True
1     True
2    False
3    False
4    False
Name: Sales, dtype: bool

I think this is what you want:

JavaScriptSerializer JSS = new JavaScriptSerializer();
T obj = JSS.Deserialize<T>(String);

The 2 main reason why you might want to prefer Mongo are

• Flexibility in schema design (JSON type document store).
• Scalability - Just add up nodes and it can scale horizontally quite well.

It is suitable for big data applications. RDBMS is not good for big data.

The first line of new text view is unnecessary

t=new TextView(this); 

you can just do this

TextView t = (TextView)findViewById(R.id.TextView01);

as far as a background thread that sleeps here is an example, but I think there is a timer that would be better for this. here is a link to a good example using a timer instead http://android-developers.blogspot.com/2007/11/stitch-in-time.html

    Thread thr = new Thread(mTask);
    thr.start();
}

Runnable mTask = new Runnable() {
    public void run() {
        // just sleep for 30 seconds.
                    try {
                        Thread.sleep(3000);
                        runOnUiThread(done);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
        }
    };

    Runnable done = new Runnable() {
        public void run() {
                   // t.setText("done");
            }
        };

So I just solved my own "SMTP connection failure" error and I wanted to post the solution just in case it helps anyone else.

I used the EXACT code given in the PHPMailer example gmail.phps file. It worked simply while I was using MAMP and then I got the SMTP connection error once I moved it on to my personal server.

All of the Stack Overflow answers I read, and all of the troubleshooting documentation from PHPMailer said that it wasn't an issue with PHPMailer. That it was a settings issue on the server side. I tried different ports (587, 465, 25), I tried 'SSL' and 'TLS' encryption. I checked that openssl was enabled in my php.ini file. I checked that there wasn't a firewall issue. Everything checked out, and still nothing.

The solution was that I had to remove this line:

$mail->isSMTP();

Now it all works. I don't know why, but it works. The rest of my code is copied and pasted from the PHPMailer example file.

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

Try this. It almost seemed to simple to be right. Simply convert the Integer to a string. Then you can use the method below or concatenate.

Dim I, J, K, L As Integer
Dim K1, L1 As String

K1 = K
L1 = L
Cells(2, 1) = K1 & " - uploaded"
Cells(3, 1) = L1 & " - expanded"

MsgBox "records uploaded " & K & " records expanded " & L

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

I am posting this answer so the topmost answer (when sorted by activity) is not one that is just plain wrong.

What is a Stacktrace?

A stacktrace is a very helpful debugging tool. It shows the call stack (meaning, the stack of functions that were called up to that point) at the time an uncaught exception was thrown (or the time the stacktrace was generated manually). This is very useful because it doesn't only show you where the error happened, but also how the program ended up in that place of the code. This leads over to the next question:

What is an Exception?

An Exception is what the runtime environment uses to tell you that an error occurred. Popular examples are NullPointerException, IndexOutOfBoundsException or ArithmeticException. Each of these are caused when you try to do something that is not possible. For example, a NullPointerException will be thrown when you try to dereference a Null-object:

Object a = null;
a.toString();                 //this line throws a NullPointerException

Object[] b = new Object[5];
System.out.println(b[10]);    //this line throws an IndexOutOfBoundsException,
                              //because b is only 5 elements long
int ia = 5;
int ib = 0;
ia = ia/ib;                   //this line throws an  ArithmeticException with the 
                              //message "/ by 0", because you are trying to
                              //divide by 0, which is not possible.

How should I deal with Stacktraces/Exceptions?

At first, find out what is causing the Exception. Try googleing the name of the exception to find out, what is the cause of that exception. Most of the time it will be caused by incorrect code. In the given examples above, all of the exceptions are caused by incorrect code. So for the NullPointerException example you could make sure that a is never null at that time. You could, for example, initialise a or include a check like this one:

if (a!=null) {
    a.toString();
}

This way, the offending line is not executed if a==null. Same goes for the other examples.

Sometimes you can't make sure that you don't get an exception. For example, if you are using a network connection in your program, you cannot stop the computer from loosing it's internet connection (e.g. you can't stop the user from disconnecting the computer's network connection). In this case the network library will probably throw an exception. Now you should catch the exception and handle it. This means, in the example with the network connection, you should try to reopen the connection or notify the user or something like that. Also, whenever you use catch, always catch only the exception you want to catch, do not use broad catch statements like catch (Exception e) that would catch all exceptions. This is very important, because otherwise you might accidentally catch the wrong exception and react in the wrong way.

try {
    Socket x = new Socket("1.1.1.1", 6789);
    x.getInputStream().read()
} catch (IOException e) {
    System.err.println("Connection could not be established, please try again later!")
}

Why should I not use catch (Exception e)?

Let's use a small example to show why you should not just catch all exceptions:

int mult(Integer a,Integer b) {
    try {
        int result = a/b
        return result;
    } catch (Exception e) {
        System.err.println("Error: Division by zero!");
        return 0;
    }
}

What this code is trying to do is to catch the ArithmeticException caused by a possible division by 0. But it also catches a possible NullPointerException that is thrown if a or b are null. This means, you might get a NullPointerException but you'll treat it as an ArithmeticException and probably do the wrong thing. In the best case you still miss that there was a NullPointerException. Stuff like that makes debugging much harder, so don't do that.

TLDR

1. Figure out what is the cause of the exception and fix it, so that it doesn't throw the exception at all.

2. If 1. is not possible, catch the specific exception and handle it.

   • Never just add a try/catch and then just ignore the exception! Don't do that!
   • Never use catch (Exception e), always catch specific Exceptions. That will save you a lot of headaches.

An expressive way to achieve reverse(enumerate(collection)) in python 3:

zip(reversed(range(len(collection))), reversed(collection))

in python 2:

izip(reversed(xrange(len(collection))), reversed(collection))

I'm not sure why we don't have a shorthand for this, eg.:

def reversed_enumerate(collection):
    return zip(reversed(range(len(collection))), reversed(collection))

or why we don't have reversed_range()

If you want to access referrer and user-agent, those are available to client-side Javascript, but not by accessing the headers directly.

To retrieve the referrer, use document.referrer.
To access the user-agent, use navigator.userAgent.

As others have indicated, the HTTP headers are not available, but you specifically asked about the referer and user-agent, which are available via Javascript.

The first one is useful when you need the index of the element as well. This is basically equivalent to the other two variants for ArrayLists, but will be really slow if you use a LinkedList.

The second one is useful when you don't need the index of the element but might need to remove the elements as you iterate. But this has the disadvantage of being a little too verbose IMO.

The third version is my preferred choice as well. It is short and works for all cases where you do not need any indexes or the underlying iterator (i.e. you are only accessing elements, not removing them or modifying the Collection in any way - which is the most common case).

The module approach works well. If I absolutely need a singleton I prefer the Metaclass approach.

class Singleton(type):
    def __init__(cls, name, bases, dict):
        super(Singleton, cls).__init__(name, bases, dict)
        cls.instance = None 

    def __call__(cls,*args,**kw):
        if cls.instance is None:
            cls.instance = super(Singleton, cls).__call__(*args, **kw)
        return cls.instance

class MyClass(object):
    __metaclass__ = Singleton

To get rid of error:

Type '"text"' is not assignable to type '"json"'.

Use

responseType: 'text' as 'json'

import { HttpClient, HttpHeaders } from '@angular/common/http';
.....
 return this.http
        .post<string>(
            this.baseUrl + '/Tickets/getTicket',
            JSON.stringify(value),
        { headers, responseType: 'text' as 'json' }
        )
        .map(res => {
            return res;
        })
        .catch(this.handleError);

Simple solution:

double totalCost = 123.45678;
totalCost = Convert.ToDouble(String.Format("{0:0.00}", totalCost));

//output: 123.45

• Use slices instead of arrays for reading. For example, io.Reader accepts a slice, not an array.

• Use slicing instead of zero padding.

Example:

buf := make([]byte, 100)
n, err := myReader.Read(buf)
if n == 0 && err != nil {
    log.Fatal(err)
}

consume(buf[:n]) // consume() will see an exact (not padded) slice of read data

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

Use the DateValue() function to convert a string to date data type. That's the easiest way of doing this.

DateValue(String Date) 

To have unique Categories:

var uniqueCategories =  repository.GetAllProducts()
                                  .Select(p=>p.Category)
                                  .Distinct();

Basically, there are two important differences between + and the concat method.

1. If you are using the concat method then you would only be able to concatenate strings while in case of the + operator, you can also concatenate the string with any data type.

   For Example:

   String s = 10 + "Hello";
   

   In this case, the output should be 10Hello.

   String s = "I";
   String s1 = s.concat("am").concat("good").concat("boy");
   System.out.println(s1);
   

   In the above case you have to provide two strings mandatory.

2. The second and main difference between + and concat is that:

   Case 1: Suppose I concat the same strings with concat operator in this way

   String s="I";
   String s1=s.concat("am").concat("good").concat("boy");
   System.out.println(s1);
   

   In this case total number of objects created in the pool are 7 like this:

   I
   am
   good
   boy
   Iam
   Iamgood
   Iamgoodboy
   

   Case 2:

   Now I am going to concatinate the same strings via + operator

   String s="I"+"am"+"good"+"boy";
   System.out.println(s);
   

   In the above case total number of objects created are only 5.

   Actually when we concatinate the strings via + operator then it maintains a StringBuffer class to perform the same task as follows:-

   StringBuffer sb = new StringBuffer("I");
   sb.append("am");
   sb.append("good");
   sb.append("boy");
   System.out.println(sb);
   

   In this way it will create only five objects.

So guys these are the basic differences between + and the concat method. Enjoy :)

I have to agree with the comments above, that you can't call a file, but you could load a JS file like this, I'm unsure if it answers your question but it may help... oh and I've used a link instead of a button in my example...

<a href='linkhref.html' id='mylink'>click me</a>

<script type="text/javascript">

var myLink = document.getElementById('mylink');

myLink.onclick = function(){

    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "Public/Scripts/filename.js."; 
    document.getElementsByTagName("head")[0].appendChild(script);
    return false;

}


</script>

This link had the clearest and most detailed step-by-step to make this error disappear for me.

In my case I had to have the key as a "System" key otherwise it did not work (which not every url mentions).

Also killing taskgated is a viable (and quicker) alternative to having to restart.

I also uninstalled MacPorts before I started this process and uninstalled the current gdb using brew uninstall gdb.

Like this:

#include <string>
#include <vector>

struct user
{
    std::string username;
    std::vector<unsigned char> userpassword;
};

int main()
{
    user r;   // r.username is "" and r.userpassword is empty
    // ...
}

Starting in v3.3 You can use updateMany

db.collection.updateMany(
   <filter>,
   <update>,
   {
     upsert: <boolean>,
     writeConcern: <document>,
     collation: <document>,
     arrayFilters: [ <filterdocument1>, ... ]
   }
)

In v2.2, the update function takes the following form:

 db.collection.update(
   <query>,
   <update>,
   { upsert: <boolean>, multi: <boolean> }
)

I have tried similar issue and works fine, try it. It can handle different orientations between PDFs.

    // array to hold list of PDF files to be merged
    $files = array("a.pdf", "b.pdf", "c.pdf");
    $pageCount = 0;
    // initiate FPDI
    $pdf = new FPDI();

    // iterate through the files
    foreach ($files AS $file) {
        // get the page count
        $pageCount = $pdf->setSourceFile($file);
        // iterate through all pages
        for ($pageNo = 1; $pageNo <= $pageCount; $pageNo++) {
            // import a page
            $templateId = $pdf->importPage($pageNo);
            // get the size of the imported page
            $size = $pdf->getTemplateSize($templateId);

            // create a page (landscape or portrait depending on the imported page size)
            if ($size['w'] > $size['h']) {
                $pdf->AddPage('L', array($size['w'], $size['h']));
            } else {
                $pdf->AddPage('P', array($size['w'], $size['h']));
            }

            // use the imported page
            $pdf->useTemplate($templateId);

            $pdf->SetFont('Helvetica');
            $pdf->SetXY(5, 5);
            $pdf->Write(8, 'Generated by FPDI');
        }
    }

"exit" is a valid variable name that can be used in your Python program. You wouldn't want to exit the interpreter when you're just trying to see the value of that variable.

Try like this:

list($width, $height) = getimagesize('path_to_image');

Make sure that:

1. You specify the correct image path there
2. The image has read access
3. Chmod image dir to 755

Also try to prefix path with $_SERVER["DOCUMENT_ROOT"], this helps sometimes when you are not able to read files.

I had to include "PROJECT_NAME/osdep.h" and that includes the os specific configurations.

I would look in other files using the types you are interested in and find where/how they are defined (by looking at includes).

If this server is visible to the outside world, It's worth checking if it's having lots of requests to connect from the outside world (i.e. people trying to break into it)

in mysql you can add MONTH keyword having the timestamp as a parameter in laravel you can do it like this

Payement::groupBy(DB::raw('MONTH(created_at)'))->get();

Supposing data is a char*. Working example using std::hex:

for(int i=0; i<data_length; ++i)
    std::cout << std::hex << (int)data[i];

Or if you want to keep it all in a string:

std::stringstream ss;
for(int i=0; i<data_length; ++i)
    ss << std::hex << (int)data[i];
std::string mystr = ss.str();

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

You don't need to write a program to do this in Linux. Just pipe the serial port through netcat:

netcat www.example.com port </dev/ttyS0 >/dev/ttyS0

Just replace the address and port information. Also, you may be using a different serial port (i.e. change the /dev/ttyS0 part). You can use the stty or setserial commands to change the parameters of the serial port (baud rate, parity, stop bits, etc.).

It appears you no longer need toggleButton.setTextOff(textOff); and toggleButton.setTextOn(textOn);. The text for each toggled state will change by merely including the relevant xml characteristics. This will override the default ON/OFF text.

<ToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/toggleText"
    android:textOff="ADD TEXT"
    android:textOn="CLOSE TEXT"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="10dp"
    android:visibility="gone"/>

Two ways to do it...

GROUP BY

SELECT RES.[CUSTOMER ID], RES,NAME, SUM(INV.AMOUNT) AS [TOTAL AMOUNT]
FROM RES_DATA RES
JOIN INV_DATA INV ON RES.[CUSTOMER ID] INV.[CUSTOMER ID]
GROUP BY RES.[CUSTOMER ID], RES,NAME

OVER

SELECT RES.[CUSTOMER ID], RES,NAME, 
       SUM(INV.AMOUNT) OVER (PARTITION RES.[CUSTOMER ID]) AS [TOTAL AMOUNT]
FROM RES_DATA RES
JOIN INV_DATA INV ON RES.[CUSTOMER ID] INV.[CUSTOMER ID]

Including the header afxwin.h signalizes use of MFC. The following instructions (based on those on CodeProject.com) could help to get MFC code compiling:

1. Download and install the Windows Driver Kit.

2. Select menu Tools > Options… > Projects and Solutions > VC++ Directories.

3. In the drop-down menu Show directories for select Include files.

4. Add the following paths (replace $(WDK_directory) with the directory where you installed Windows Driver Kit in the first step):

   $(WDK_directory)\inc\mfc42
   $(WDK_directory)\inc\atl30
   

   

5. In the drop-down menu Show directories for select Library files and add (replace $(WDK_directory) like before):

   $(WDK_directory)\lib\mfc\i386
   $(WDK_directory)\lib\atl\i386
   

   

6. In the $(WDK_directory)\inc\mfc42\afxwin.inl file, edit the following lines (starting from 1033):

   _AFXWIN_INLINE CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   to

   _AFXWIN_INLINE BOOL CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE BOOL CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   In other words, add BOOL after _AFXWIN_INLINE.
