store all your data initially

function PhoneListCtrl($scope, $http) {
  $http.get('phones/phones.json').success(function(data) {
    $scope.phones = data.splice(0, 5);
    $scope.allPhones = data;
  });

  $scope.orderProp = 'age';
  $scope.howMany = 5;
  //then here watch the howMany variable on the scope and update the phones array accordingly
  $scope.$watch("howMany", function(newValue, oldValue){
    $scope.phones = $scope.allPhones.splice(0,newValue)
  });
}

EDIT had accidentally put the watch outside the controller it should have been inside.

Use alias when defining Controller in your angular configuration. For example: NOTE: I'm using TypeScript here

Just take note of the Controller, it has an alias of homeCtrl.

module MongoAngular {
    var app = angular.module('mongoAngular', ['ngResource', 'ngRoute','restangular']);

    app.config([
        '$routeProvider', ($routeProvider: ng.route.IRouteProvider) => {
            $routeProvider
                .when('/Home', {
                    templateUrl: '/PartialViews/Home/home.html',
                    controller: 'HomeController as homeCtrl'
                })
                .otherwise({ redirectTo: '/Home' });
        }])
        .config(['RestangularProvider', (restangularProvider: restangular.IProvider) => {
        restangularProvider.setBaseUrl('/api');
    }]);
} 

And here's the way to use it...

ng-click="homeCtrl.addCustomer(customer)"

Try it.. It might work for you as it worked for me... ;)

Whenever you do some form of operation outside of AngularJS, such as doing an Ajax call with jQuery, or binding an event to an element like you have here you need to let AngularJS know to update itself. Here is the code change you need to do:

app.directive("remove", function () {
    return function (scope, element, attrs) {
        element.bind ("mousedown", function () {
            scope.remove(element);
            scope.$apply();
        })
    };

});

app.directive("resize", function () {
    return function (scope, element, attrs) {
        element.bind ("mousedown", function () {
            scope.resize(element);
            scope.$apply();
        })
    };
});

Here is the documentation on it: https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$apply

My solution is create .htaccess and use #Sorian code.. without .htaccess I failed to remove #

RewriteEngine   On
RewriteBase     /
RewriteCond     %{REQUEST_URI} !^(/index\.php|/img|/js|/css|/robots\.txt|/favicon\.ico)
RewriteCond     %{REQUEST_FILENAME} !-f
RewriteCond     %{REQUEST_FILENAME} !-d
RewriteRule     ./index.html [L]

Before I show you how to reload / refresh model data from the server programmatically? I have to explain for you the concept of Data Binding. This is an extremely powerful concept that will truly revolutionize the way you develop. So may be you have to read about this concept from this link or this seconde link in order to unterstand how AngularjS work.

now I'll show you a sample example that exaplain how can you update your model from server.

HTML Code:

<div ng-controller="PersonListCtrl">
    <ul>
        <li ng-repeat="person in persons">
            Name: {{person.name}}, Age {{person.age}}
        </li>
    </ul>
   <button ng-click="updateData()">Refresh Data</button>
</div>

So our controller named: PersonListCtrl and our Model named: persons. go to your Controller js in order to develop the function named: updateData() that will be invoked when we are need to update and refresh our Model persons.

Javascript Code:

app.controller('adsController', function($log,$scope,...){

.....

$scope.updateData = function(){
$http.get('/persons').success(function(data) {
       $scope.persons = data;// Update Model-- Line X
     });
}

});

Now I explain for you how it work: when user click on button Refresh Data, the server will call to function updateData() and inside this function we will invoke our web service by the function $http.get() and when we have the result from our ws we will affect it to our model (Line X).Dice that affects the results for our model, our View of this list will be changed with new Data.

To add my own experience in here, I was trying to inject a service into one of my module config functions. This paragraph from the docs which I eventually found explains why that doesn't work:

During application bootstrap, before Angular goes off creating all services, it configures and instantiates all providers. We call this the configuration phase of the application life-cycle. During this phase, services aren't accessible because they haven't been created yet.

Meaning you can inject providers into module.config(...) functions, but you can't inject services, for that you need to wait until module.run(...), or expose a provider you can inject to module.config

Check out this directive: https://github.com/samu/angular-table

It automates sorting and pagination a lot and gives you enough freedom to customize your table/list however you want.

Simplified example (with counter):

With Me.lstbox
    .ColumnCount = 2
    .ColumnWidths = "60;60"
    .AddItem
    .List(i, 0) = Company_ID
    .List(i, 1) = Company_name 
    i = i + 1

end with

Make sure to start the counter with 0, not 1 to fill up a listbox.

I faced this problem for one month,Putting context tag inside server.xml is not safe it affect context elements deploying for all other host ,for big apps it take connection errors also not good isolation for example you may access other sites by folder name domain2.com/domain1Folder !! also database session connections loaded twice ! the other way is put ROOT.xml file that has context tag with full path such :

 <Context path="" docBase="/var/lib/tomcat7/webapps/ROOT" />

in conf/catalina/webappsfoldername and deploy war file as ROOT.war inside webappsfoldername and also specify host such

 <Host name="domianname"  appBase="webapps2" unpackWARs="true"  autoDeploy="true"  xmlValidation="false" xmlNamespaceAware="false" >

        <Logger className="org.apache.catalina.logger.FileLogger"
               directory="logs"  prefix="localhost_log." suffix=".txt"
          timestamp="true"/>
</Host>

In this approach also for same type apps user sessions has not good isolation ! you may inside app1 if app1 same as app2 you may after login by server side session automatically can login to app2 ?! So you have to keep users session in client side cache and not with jsessionid ! we may change engine name from localhost to solve it. but let say playing with tomcat need more time than play with other cats!

Assuming that you mean "When using ajax" and "An HTTP Request header", then use the headers property in the object you pass to ajax()

headers(added 1.5)

Default: {}

A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.

— http://api.jquery.com/jQuery.ajax/

Keyword parameters allow you to pass variables from one function to another. In this way you can use the key of a dictionary as a variable name (which can be populated in your while loop). The dictionary name just needs to be preceded by ** when it is called.

# create a dictionary
>>> kwargs = {}
# add a key of name and assign it a value, later we'll use this key as a variable
>>> kwargs['name'] = 'python'

# an example function to use the variable
>>> def print_name(name):
...   print name

# call the example function
>>> print_name(**kwargs)
python

Without **, kwargs is just a dictionary:

>>> print_name(kwargs)
{'name': 'python'}

The regular expression for this is really simple. Just use a character class. The hyphen is a special character in character classes, so it needs to be first:

/[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/

You also need to escape the other regular expression metacharacters.

Edit: The hyphen is special because it can be used to represent a range of characters. This same character class can be simplified with ranges to this:

/[$-/:-?{-~!"^_`\[\]]/

There are three ranges. '$' to '/', ':' to '?', and '{' to '~'. the last string of characters can't be represented more simply with a range: !"^_`[].

Use an ACSII table to find ranges for character classes.

Combining answers in this thread, this is how I fixed it(Visual Studio 2019):

1. Start Visual Studio as an Administrator and Run your Web Service as you normally do.

2. Find IIS Express icon on the taskbar, right click on it then click "Show All Applications".

3. Select your Web Service and note the config path displayed below. Click on the config file to open it for editing.

4. Find your web service(example search for your port) in this config file then find a line like this: *:yourport:localhost

5. Add a new line after that like this:

   :yourport:*

In this case no need to create bindings with specific ip address which could change in the future.

I hope this helps someone out there.

The mistake I made that coerced this error was attempting to rename a column in a loop that I was no longer selecting in my SQL. This could also be caused by trying to do the same thing in a column that you were planning to select. Make sure the column that you are trying to change actually exists.

IF "%1"=="" will fail, all versions of this will fail under certain poison character conditions. Only IF DEFINED or IF NOT DEFINED are safe

Not a definite answer but too much to fit in comments:

I hypothesize they gave you a cert that either has a wrong issuer (although their server could use a more specific alert code for that) or a wrong subject. We know the cert matches your privatekey -- because both curl and openssl client paired them without complaining about a mismatch; but we don't actually know it matches their desired CA(s) -- because your curl uses openssl and openssl SSL client does NOT enforce that a configured client cert matches certreq.CAs.

Do openssl x509 <clientcert.pem -noout -subject -issuer and the same on the cert from the test P12 that works. Do openssl s_client (or check the one you did) and look under Acceptable client certificate CA names; the name there or one of them should match (exactly!) the issuer(s) of your certs. If not, that's most likely your problem and you need to check with them you submitted your CSR to the correct place and in the correct way. Perhaps they have different regimes in different regions, or business lines, or test vs prod, or active vs pending, etc.

If the issuer of your cert does match desiredCAs, compare its subject to the working (test-P12) one: are they in similar format? are there any components in the working one not present in yours? If they allow it, try generating and submitting a new CSR with a subject name exactly the same as the test-P12 one, or as close as you can get, and see if that produces a cert that works better. (You don't have to generate a new key to do this, but if you choose to, keep track of which certs match which keys so you don't get them mixed up.) If that doesn't help look at the certificate extensions with openssl x509 <cert -noout -text for any difference(s) that might reasonably be related to subject authorization, like KeyUsage, ExtendedKeyUsage, maybe Policy, maybe Constraints, maybe even something nonstandard.

If all else fails, ask the server operator(s) what their logs say about the problem, or if you have access look at the logs yourself.

From grep --help, but also see man grep:

Exit status is 0 if any line was selected, 1 otherwise; if any error occurs and -q was not given, the exit status is 2.

if grep --quiet MYSQL_ROLE=master /etc/aws/hosts.conf; then
  echo exists
else
  echo not found
fi

You may want to use a more specific regex, such as ^MYSQL_ROLE=master$, to avoid that string in comments, names that merely start with "master", etc.

This works because the if takes a command and runs it, and uses the return value of that command to decide how to proceed, with zero meaning true and non-zero meaning false—the same as how other return codes are interpreted by the shell, and the opposite of a language like C.

If you already have var parent = document.querySelector('.parent'); you can do this to scope the search to parent's children:

parent.querySelector('.child')

Hide scroll bar, but while still being able to scroll using CSS

To hide the scrollbar use -webkit- because it is supported by major browsers (Google Chrome, Safari or newer versions of Opera). There are many other options for the other browsers which are listed below:

    -webkit- (Chrome, Safari, newer versions of Opera):
    .element::-webkit-scrollbar { width: 0 !important }
    -moz- (Firefox):
    .element { overflow: -moz-scrollbars-none; }
    -ms- (Internet Explorer +10):
    .element { -ms-overflow-style: none; }

ref: https://www.geeksforgeeks.org/hide-scroll-bar-but-while-still-being-able-to-scroll-using-css/

here it is, obtaining a reference to the coresponding pointer of an iterator use :

example:

string my_str= "hello world";

string::iterator it(my_str.begin());

char* pointer_inside_buffer=&(*it); //<--

[notice operator * returns a reference so doing & on a reference will give you the address].

You can find the commit id related to each commit in the commits section of GitHub/BitBucket/Gitlab. Its very simple, suppose your commit id is 5889575 then if you want to go back to this part in your code then you simply need to type

git checkout 5889575 .

This will take you to that point of time in your code.

The syntax

variable=value command

is often used to set an environment variables for a specific process. However, you must understand which process gets what variable and who interprets it. As an example, using two shells:

a=5
# variable expansion by the current shell:
a=3 bash -c "echo $a"
# variable expansion by the second shell:
a=3 bash -c 'echo $a'

The result will be 5 for the first echo and 3 for the second.

For an attribute value that needs to be interpolated in a directive that is not using an isolated scope, e.g.,

<input my-directive value="{{1+1}}">

use Attributes' method $observe:

myApp.directive('myDirective', function () {
  return function (scope, element, attr) {
    attr.$observe('value', function(actual_value) {
      element.val("value = "+ actual_value);
    })
 }
});

From the directive page,

observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.

If the attribute value is just a constant, e.g.,

<input my-directive value="123">

you can use $eval if the value is a number or boolean, and you want the correct type:

return function (scope, element, attr) {
   var number = scope.$eval(attr.value);
   console.log(number, number + 1);
});

If the attribute value is a string constant, or you want the value to be string type in your directive, you can access it directly:

return function (scope, element, attr) {
   var str = attr.value;
   console.log(str, str + " more");
});

In your case, however, since you want to support interpolated values and constants, use $observe.

I think you can also execute this command:

select (sysdate-1) PREVIOUS_DATE from dual;

Another option, if you prefer, would be to get the DOM element from the jQuery object and use standard DOM accessors on it:

$("#myElement")[0].title = "new title value";

The "jQuery way", as mentioned by others, is to use the attr() method. See the API documentation for attr() here.

To match pattern or an empty string, use

^$|pattern

Explanation

• ^ and $ are the beginning and end of the string anchors respectively.
• | is used to denote alternates, e.g. this|that.

References

• regular-expressions.info/Anchors and Alternation

On \b

\b in most flavor is a "word boundary" anchor. It is a zero-width match, i.e. an empty string, but it only matches those strings at very specific places, namely at the boundaries of a word.

That is, \b is located:

• Between consecutive \w and \W (either order):
  • i.e. between a word character and a non-word character
• Between ^ and \w
  • i.e. at the beginning of the string if it starts with \w
• Between \w and $
  • i.e. at the end of the string if it ends with \w

References

• regular-expressions.info/Word Boundaries

On using regex to match e-mail addresses

This is not trivial depending on specification.

Related questions

• What is the best regular expression for validating email addresses?
• Regexp recognition of email address hard?
• How far should one take e-mail address validation?

Use transform: scale(...); and add matching margin: -...px to compensate free space from scaling. (you can use * {outline: 1px solid}to see element boundaries).

I think what the questioner is after is converting the string representation of a hexadecimal value to a byte array representing that hexadecimal value.

The apache commons-codec has a class for that, Hex.

String s = "9B7D2C34A366BF890C730641E6CECF6F";    
byte[] bytes = Hex.decodeHex(s.toCharArray());

In case you don't want to use API 21 as the target API, and thus you don' t want to use the Material Theme, you have to use an older revision belonging to API 19 >

compile "com.android.support:appcompat-v7:19.0.+"

This also helps solving your problem, it only depends on what you want to achieve.

Use:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= TRUNC(SYSDATE) - 30

SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.

Depending on your needs, you could also look at using ADD_MONTHS:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)

You can use Environment.CurrentDirectory to get the current directory, and FileSystemInfo.FullPath to get the full path to any location. So, fully qualify both the current directory and the file in question, and then check whether the full file name starts with the directory name - if it does, just take the appropriate substring based on the directory name's length.

Here's some sample code:

using System;
using System.IO;

class Program
{
    public static void Main(string[] args)
    {
        string currentDir = Environment.CurrentDirectory;
        DirectoryInfo directory = new DirectoryInfo(currentDir);
        FileInfo file = new FileInfo(args[0]);

        string fullDirectory = directory.FullName;
        string fullFile = file.FullName;

        if (!fullFile.StartsWith(fullDirectory))
        {
            Console.WriteLine("Unable to make relative path");
        }
        else
        {
            // The +1 is to avoid the directory separator
            Console.WriteLine("Relative path: {0}",
                              fullFile.Substring(fullDirectory.Length+1));
        }
    }
}

I'm not saying it's the most robust thing in the world (symlinks could probably confuse it) but it's probably okay if this is just a tool you'll be using occasionally.

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

If you have assigned a certain controller to your view, then your controller will be invoked every time your view loads. In that case, you can execute some code in your controller as soon as it is invoked, for example this way:

<ion-nav-view ng-controller="indexController" name="other" ng-init="doSomething()"></ion-nav-view>

And in your controller:

app.controller('indexController', function($scope) {
    /*
        Write some code directly over here without any function,
        and it will be executed every time your view loads.
        Something like this:
    */
    $scope.xyz = 1;
});

Edit: You might try to track state changes and then execute some code when the route is changed and a certain route is visited, for example:

$rootScope.$on('$stateChangeSuccess', 
function(event, toState, toParams, fromState, fromParams){ ... })

You can find more details here: State Change Events.

This is your code

<ListView Name="lstCustomers" ItemsSource="{Binding Path=Collection}">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="ID" DisplayMemberBinding="{Binding Id}" Width="40"/>
            <GridViewColumn Header="First Name" DisplayMemberBinding="{Binding FirstName}" Width="100" />
            <GridViewColumn Header="Last Name" DisplayMemberBinding="{Binding LastName}"/>
        </GridView>
    </ListView.View>
</ListView>

Try this

<ListView Name="lstCustomers" ItemsSource="{Binding Path=Collection}">
    <ListView.View>
        <GridView>
            <GridViewColumn DisplayMemberBinding="{Binding Id}" Width="Auto">
               <GridViewColumnHeader Content="ID" Width="Auto" />
            </GridViewColumn>
            <GridViewColumn DisplayMemberBinding="{Binding FirstName}" Width="Auto">
              <GridViewColumnHeader Content="First Name" Width="Auto" />
            </GridViewColumn>
            <GridViewColumn DisplayMemberBinding="{Binding LastName}" Width="Auto">
              <GridViewColumnHeader Content="Last Name" Width="Auto" />
            </GridViewColumn
        </GridView>
    </ListView.View>
</ListView>

Try this, if your input is string 
For example 

string input= "13:01";
string[] arry = input.Split(':');                  
string timeinput = arry[0] + arry[1];
private string Convert24To12HourInEnglish(string timeinput)

 {

DateTime startTime = new DateTime(2018, 1, 1, int.Parse(timeinput.Substring(0, 2)), 
int.Parse(timeinput.Substring(2, 2)), 0); 
return startTime.ToString("hh:mm tt");

}
out put: 01:01

If you are using the GET request to actually SEND data...

check: http://techhelplist.com/index.php/tech-tutorials/37-windows-troubles/60-vbscript-sending-get-request

The problem with MSXML2.XMLHTTP is that there are several versions of it, with different names depending on the windows os version and patches.

this explains it: http://support.microsoft.com/kb/269238

i have had more luck using vbscript to call

set ID = CreateObject("InternetExplorer.Application")
IE.visible = 0
IE.navigate "http://example.com/parser.php?key=" & value & "key2=" & value2 
do while IE.Busy.... 

....and more stuff but just to let the request go thru.

I found that when you create an input filter to avoid entry of unwanted characters, pasting such characters into the edit text is having no effect. So this sort of solves my problem as well.

I was able to overcome this by using the "vh" metric with max-height on the .modal-body element. 70vh looked about right for my uses.

.modal-body {
   overflow-y: auto;
   max-height: 70vh;
}

In my case I had an issue around using Microsoft.ReportViewer.WebForms. I removed validate=true from add verb line in web.config and it started working:

<system.web>
    <httpHandlers>
      <add verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

I needed something similar, and came up with using the :before (or :after) pseudoclasses:

#mydiv {
   background-color: #fbb;
   margin-top: 100px;
   position: relative;
}
#mydiv:before {
   content: "";
   background-color: #bfb;
   top: -100px;
   height: 100px;
   width: 100%;
   position: absolute;
}

Doing password checks on client side is unsafe especially when the password is hard coded.

The safest way is password checking on server side, but even then the password should not be transmitted plain text.

Checking the password client side is possible in a "secure way":

• The password needs to be hashed
• The hashed password is used as part of a new url

Say "abc" is your password so your md5 would be "900150983cd24fb0d6963f7d28e17f72" (consider salting!). Now build a url containing the hash (like http://yourdomain.com/90015...f72.html).

You've got the syntax all wrong:

cursor.execute ("""
   UPDATE tblTableName
   SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
   WHERE Server=%s
""", (Year, Month, Day, Hour, Minute, ServerID))

For more, read the documentation.

Use the View's post method like this

post(new Runnable() {   
    @Override
    public void run() {
        Log.d(TAG, "width " + MyView.this.getMeasuredWidth());
        }
    });

Use shelljs

npm i -D shelljs

const bash = require('shelljs');
bash.cp("-rf", "/path/to/source/folder", "/path/to/destination/folder");

http://www.firstobject.com/dn_editor.htm is so far the best and lightest editor available with handful of utilities. I recommend using it - tried with up to 400 MB of files and more than a million records :)

There is a better way you can handle the import of modules in your React App. Consider doing this:

Add a jsconfig.json file to your base folder. That is the same folder containing your package.json. Next define your base URL imports in it:

//jsconfig.json
{
  "compilerOptions": {
    "baseUrl": "./src"
  }
}

Now rather than calling ../../ you can easily do this instead:

import navBar from 'components/header/navBar'
import 'css/header.css'

Notice that 'components/' is different from '../components/'

It's neater this way.

But if you want to import files in the same directory you can do this also:

import logo from './logo.svg'

Here is a jQuery plugin that does exactly that: http://fixedheadertable.com/

Usage:

$('selector').fixedHeaderTable({ fixedColumn: 1 });

Set the fixedColumn option if you want any number of columns to be also fixed for horizontal scrolling.

EDIT: This example http://www.datatables.net/examples/basic_init/scroll_y.html is much better in my opinion, although with DataTables you'll need to get a better understanding of how it works in general.

EDIT2: For Bootstrap to work with DataTables you need to follow the instructions here: http://datatables.net/blog/Twitter_Bootstrap_2 (I have tested this and it works)- For Bootstrap 3 there's a discussion here: http://datatables.net/forums/discussion/comment/53462 - (I haven't tested this)

continue is kind of like goto. Are you familiar with break? It's easier to think about them in contrast:

• break terminates the loop (jumps to the code below it).

• continue terminates the rest of the processing of the code within the loop for the current iteration, but continues the loop.

$('selector').css('cursor', 'pointer'); // 'default' to revert

I know that may be confusing per your original question, but the "finger" cursor is actually called "pointer".

The normal arrow cursor is just "default".

all possible default pointer looks DEMO

Seems like last_accessed_on, is a date time, and you are converting '23-07-2014 09:37:00' to a varchar. This would not work, and give you conversion errors. Try

last_accessed_on= convert(datetime,'23-07-2014 09:37:00', 103)  

I think you can avoid the cast though, and update with '23-07-2014 09:37:00'. It should work given that the format is correct.

Your query is not going to work because in last_accessed_on (which is DateTime2 type), you are trying to pass a Varchar value.

You query would be

UPDATE  student_queues SET  Deleted=0 ,  last_accessed_by='raja', last_accessed_on=convert(datetime,'23-07-2014 09:37:00', 103)  
 WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

As an aside, it is always a good practice (and possibly a solution for this type of issue) to delete a large number of rows by using batches:

WHILE EXISTS (SELECT 1 
              FROM   YourTable 
              WHERE  <yourCondition>) 
  DELETE TOP(10000) FROM YourTable 
  WHERE  <yourCondition>

POSIX defines a function: wait(NULL);. It's the shorthand for waitpid(-1, NULL, 0);, which will suspends the execution of the calling process until any one child process exits. Here, 1st argument of waitpid indicates wait for any child process to end.

In your case, have the parent call it from within your else branch.

First - most classes will never need to be thread-safe. Use YAGNI: only apply thread-safety when you know you actually are going to use it (and test it).

For the method-level stuff, there is [MethodImpl]:

[MethodImpl(MethodImplOptions.Synchronized)]
public void SomeMethod() {/* code */}

This can also be used on accessors (properties and events):

private int i;
public int SomeProperty
{
    [MethodImpl(MethodImplOptions.Synchronized)]
    get { return i; }
    [MethodImpl(MethodImplOptions.Synchronized)]
    set { i = value; }
}

Note that field-like events are synchronized by default, while auto-implemented properties are not:

public int SomeProperty {get;set;} // not synchronized
public event EventHandler SomeEvent; // synchronized

Personally, I don't like the implementation of MethodImpl as it locks this or typeof(Foo) - which is against best practice. The preferred option is to use your own locks:

private readonly object syncLock = new object();
public void SomeMethod() {
    lock(syncLock) { /* code */ }
}

Note that for field-like events, the locking implementation is dependent on the compiler; in older Microsoft compilers it is a lock(this) / lock(Type) - however, in more recent compilers it uses Interlocked updates - so thread-safe without the nasty parts.

This allows more granular usage, and allows use of Monitor.Wait/Monitor.Pulse etc to communicate between threads.

A related blog entry (later revisited).

One possible solution might be setting a flag while showing the system-dialog and then in the onStop method of the activity life-cycle, check for the flag, if true, finish the activity.

For example, if the system dialog is triggered by some buttonclick, then the onclick listener might be like

private OnClickListener btnClickListener = new OnClickListener() {

    @Override
    public void onClick(View v) {           
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_SEND);
        intent.setType("text/plain");
        CheckActivity.this.startActivity(Intent.createChooser(intent, "Complete action using"));
        checkFlag = true;  //flag used to check

    }
};

and in onstop of activity:

@Override
protected void onStop() {
    if(checkFlag){
        finish();
    }
    super.onStop();
}

Nice question/answers.

Just want to point out that C pointers and arrays are not the same, although in this case the difference is not essential.

Consider the following declarations:

int a[10];
int* p = a;

In a.out, the symbol a is at an address that's the beginning of the array, and symbol p is at an address where a pointer is stored, and the value of the pointer at that memory location is the beginning of the array.

There is a discussion about it here.

https://github.com/angular/angular.io/issues/2663

Alex J's answer is good but it no longer works with current Angular 4 as of July, 2017.

And this plunker link would demonstrate how to communicate between siblings using shared service and observable.

If you are on a Windows machine and have the Git installed, you can try the below steps:

1. Go to the folder of Git installation, ex: C:\Program Files (x86)\Git\etc
2. Edit the file: gitconfig

3. Under the [http] section, add the line: sslVerify = false

   [http]
     sslVerify = false
   

Dude I know totally how you feel, but don't forget about inline styling. It is almost the super saiyan of the CSS specificity

So it should look something like this for you,

<span class="icon-bar" style="background-color: black !important;">
</span>
<span class="icon-bar" style="background-color: black !important;">
</span>
<span class="icon-bar" style="background-color: black !important;">
</span>

It looks like the return value is in an array? That's somewhat strange... and also be aware that certain browsers will allow that to be parsed from a cross-domain request (which isn't true when you have a top-level JSON object).

Anyway, if that is an array wrapper, you'll want something like this:

$('#my-hidden-field').val(theObject[0].id);

You can later retrieve it through a simple .val() call on the same field. This honestly looks kind of strange though. The hidden field won't persist across page requests, so why don't you just keep it in your own (pseudo-namespaced) value bucket? E.g.,

$MyNamespace = $MyNamespace || {};
$MyNamespace.myKey = theObject;

This will make it available to you from anywhere, without any hacky input field management. It's also a lot more efficient than doing DOM modification for simple value storage.

You can try https://rubygems.org/gems/dates_from_string:

Find date in structure:

text = "get car from repair 2015-02-02 23:00:10"
dates_from_string = DatesFromString.new
dates_from_string.find_date(text)

=> ["2015-02-02 23:00:10"]

Format with Currency format string

=Format(Fields!Price.Value, "C")

It will give you 2 decimal places with "$" prefixed.

You can find other format strings on MSDN: Adding Style and Formatting to a ReportViewer Report

Note: The MSDN article has been archived to the "VS2005_General" document, which is no longer directly accessible online. Here is the excerpt of the formatting strings referenced:

Formatting Numbers

The following table lists common .NET Framework number formatting strings.

Format string, Name

C or c Currency

D or d Decimal

E or e Scientific

F or f Fixed-point

G or g General

N or n Number

P or p Percentage

R or r Round-trip

X or x Hexadecimal

You can modify many of the format strings to include a precision specifier that defines the number of digits to the right of the

decimal point. For example, a formatting string of D0 formats the number so that it has no digits after the decimal point. You

can also use custom formatting strings, for example, #,###.

Formatting Dates

The following table lists common .NET Framework date formatting strings.

Format string, Name

d Short date

D Long date

t Short time

T Long time

f Full date/time (short time)

F Full date/time (long time)

g General date/time (short time)

G General date/time (long time)

M or m Month day

R or r RFC1123 pattern

Y or y Year month

You can also a use custom formatting strings; for example, dd/MM/yy. For more information about .NET Framework formatting strings, see Formatting Types.

With jQuery, I've done it this way:

function checkKey(e){
     switch (e.keyCode) {
        case 40:
            alert('down');
            break;
        case 38:
            alert('up');
            break;
        case 37:
            alert('left');
            break;
        case 39:
            alert('right');
            break;
        default:
            alert('???');  
            }      
}

if ($.browser.mozilla) {
    $(document).keypress (checkKey);
} else {
    $(document).keydown (checkKey);
}

Also, try these plugins, which looks like they do all that work for you:

This is behaviour of floating point arithmetic is by specification. Excerpt from the specification, § 15.17.2. Division Operator /:

Division of a nonzero finite value by a zero results in a signed infinity. The sign is determined by the rule stated above.

Restarting Visual Studio 2019 - that did it.

It should not happen. However, when .NET is under a heavy load, it is possible to get duplicate guids. I have two different web servers using two different sql servers. I went to merge the data and found I had 15 million guids and 7 duplicates.

Here is another way

$( '#iframe' ).attr( 'src', function () { return $( this )[0].src; } );

Alternatively, you can use numpy underlying function:

>>> import numpy as np
>>> df = pd.DataFrame({"A": [10,20,30], "B": [20, 30, 10]})
>>> df['new_column'] = np.multiply(df['A'], df['B'])
>>> df
    A   B  new_column
0  10  20         200
1  20  30         600
2  30  10         300

or vectorize arbitrary function in general case:

>>> def fx(x, y):
...     return x*y
...
>>> df['new_column'] = np.vectorize(fx)(df['A'], df['B'])
>>> df
    A   B  new_column
0  10  20         200
1  20  30         600
2  30  10         300

You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

indexPathForRow is a class method!

The code should read:

NSIndexPath *myIP = [NSIndexPath indexPathForRow:0 inSection:0] ;

use this css class for your input at start, then customize accordingly:

    _x000D_
 .inp-icon{_x000D_
background: url(https://i.imgur.com/kSROoEB.png)no-repeat 100%;_x000D_
background-size: 16px;_x000D_
 }

<input class="inp-icon" type="text">

The top answer [[ $b = 5 ]] && a="$c" || a="$d" should only be used if you are certain there will be no error after the &&, otherwise it will incorrectly excute the part after the ||.

To solve that problem I wrote a ternary function that behaves as it should and it even uses the ? and : operators:

Edit - new solution

Here is my new solution that does not use $IFS nor ev(a/i)l.

function executeCmds()
{
    declare s s1 s2 i j k
    declare -A cmdParts
    declare pIFS=$IFS
    IFS=$'\n'
    declare results=($(echo "$1" | grep -oP '{ .*? }'))
    IFS=$pIFS
    s="$1"
    for ((i=0; i < ${#results[@]}; i++)); do
        s="${s/${results[$i]}/'\0'}"
        results[$i]="${results[$i]:2:${#results[$i]}-3}"
        results[$i]=$(echo ${results[$i]%%";"*})
    done
    s="$s&&"
    let cmdParts[t]=0
    while :; do
        i=${cmdParts[t]}
        let cmdParts[$i,t]=0
        s1="${s%%"&&"*}||"
        while :; do
            j=${cmdParts[$i,t]}
            let cmdParts[$i,$j,t]=0
            s2="${s1%%"||"*};"
            while :; do
                cmdParts[$i,$j,${cmdParts[$i,$j,t]}]=$(echo ${s2%%";"*})
                s2=${s2#*";"}
                let cmdParts[$i,$j,t]++
                [[ $s2 ]] && continue
                break
            done
            s1=${s1#*"||"}
            let cmdParts[$i,t]++
            [[ $s1 ]] && continue
            break
        done
        let cmdParts[t]++
        s=${s#*"&&"}
        [[ $s ]] && continue
        break
    done
    declare lastError=0
    declare skipNext=false
    for ((i=0; i < ${cmdParts[t]}; i++ )) ; do
        let j=0
        while :; do
            let k=0
            while :; do
                if $skipNext; then
                    skipNext=false
                else
                    if [[ "${cmdParts[$i,$j,$k]}" == "\0" ]]; then
                         executeCmds "${results[0]}" && lastError=0 || lastError=1
                         results=("${results[@]:1}")
                    elif [[ "${cmdParts[$i,$j,$k]:0:1}" == "!" || "${cmdParts[$i,$j,$k]:0:1}" == "-" ]]; then
                        [ ${cmdParts[$i,$j,$k]} ] && lastError=0 || lastError=1
                    else
                        ${cmdParts[$i,$j,$k]}
                        lastError=$?
                    fi
                    if (( k+1 < cmdParts[$i,$j,t] )); then
                        skipNext=false
                    elif (( j+1 < cmdParts[$i,t] )); then
                        (( lastError==0 )) && skipNext=true || skipNext=false
                    elif (( i+1 < cmdParts[t] )); then
                        (( lastError==0 )) && skipNext=false || skipNext=true
                    fi
                fi
                let k++
                [[ $k<${cmdParts[$i,$j,t]} ]] || break
            done
            let j++
            [[ $j<${cmdParts[$i,t]} ]] || break
        done
    done
    return $lastError
}

function t()
{
    declare commands="$@"
    find="$(echo ?)"
    replace='?'
    commands="${commands/$find/$replace}"
    readarray -d '?' -t statement <<< "$commands"
    condition=${statement[0]}
    readarray -d ':' -t statement <<< "${statement[1]}"
    success="${statement[0]}"
    failure="${statement[1]}"
    executeCmds "$condition" || { executeCmds "$failure"; return; }
    executeCmds "$success"
}

executeCmds separates each command individually, apart from the ones that should be skipped due to the && and || operators. It uses [] whenever a command starts with ! or a flag.

There are two ways to pass commands to it:

1. Pass the individual commands unquoted but be sure to quote ;, &&, and || operators.

t ls / ? ls qqq '||' echo aaa : echo bbb '&&' ls qq

2. Pass all the commands quoted:

t 'ls /a ? ls qqq || echo aaa : echo bbb && ls qq'

NB I found no way to pass in && and || operators as parameters unquoted, as they are illegal characters for function names and aliases, and I found no way to override bash operators.

Old solution - uses ev(a/i)l

function t()
{
    pIFS=$IFS
    IFS="?"
    read condition success <<< "$@"
    IFS=":"
    read success failure <<< "$success"
    IFS=$pIFS
    eval "$condition" || { eval "$failure" ; return; }
    eval "$success"
}
t ls / ? ls qqq '||' echo aaa : echo bbb '&&' ls qq
t 'ls /a ? ls qqq || echo aaa : echo bbb && ls qq'

It's a reasonable idea to want to script an FTP session the way the original poster imagined, and that is the kind of thing Expect would help with. Batch files on Windows cannot do this.

But rather than doing cURL or Expect, you may find it easier to script the FTP interaction with Powershell. It's a different model, in that you are not directly scripting the text to send to the FTP server. Instead you will use Powershell to manipulate objects that generate the FTP dialogue for you.

Upload:

$File = "D:\Dev\somefilename.zip"
$ftp = "ftp://username:[email protected]/pub/incoming/somefilename.zip"

"ftp url: $ftp"

$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($ftp)

"Uploading $File..."

$webclient.UploadFile($uri, $File)

Download:

$File = "c:\store\somefilename.zip"
$ftp = "ftp://username:[email protected]/pub/outbound/somefilename.zip"

"ftp url: $ftp"

$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($ftp)

"Downloading $File..."

$webclient.DownloadFile($uri, $File)

You need Powershell to do this. If you are not aware, Powershell is a shell like cmd.exe which runs your .bat files. But Powershell runs .ps1 files, and is quite a bit more powerful. Powershell is a free add-on to Windows and will be built-in to future versions of Windows. Get it here.

The ConnectTimeout option allows you to tell your ssh client how long you're willing to wait for a connection before returning an error. By setting ConnectTimeout to 1, you're effectively saying "try for at most 1 second and then fail if you haven't connected yet".

The problem is that when you connect by name, the DNS lookup can take several seconds. Connecting by IP address is much faster, and may actually work in one second or less. What sinelaw is experiencing is that every attempt to connect by DNS name is failing to occur within one second. The default setting of ConnectTimeout defers to the linux kernel connect timeout, which is usually pretty long.

I had this problem when I started using Entity Framework, it happened when I did not change the old SQL server connection to EntityFrameWork connection.

Solution: in the file where connection is made through web.config file "add name="Entities" connectionString=XYZ", make sure you are referring to the correct connection, in my case I had to do this

        public static string MyEntityFrameworkConnection
    {
        get
        {
             return ConfigurationManager.ConnectionStrings["Entities"].ConnectionString;
        }

    }

call MyEntityFrameworkConnection whenever connection need to be established.

private string strConnection= Library.DataAccessLayer.DBfile.AdoSomething.MyEntityFrameworkConnection;

note: the connection in web.config file will be generated automatically when adding Entity model to the solution.

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

Sticky on hover, HTML:

<a href="javascript:;" data-toggle="popover" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus." title="Lorem Ipsum">...</a>

      var el = this;
      $(el).popover('show');
      $(".popover > h3").append('<span class="close icon icon-remove"></span>')
                        .find('.close').on('click', function(e) {
                            e.preventDefault();
                            $(el).popover('hide');
                        }
      );
  }
});

If you wanna install opencv for python version 3.7, heres how you do it!

py -3.7 -m pip install opencv-python

An easy fix

If you have only one type of collections (e.g. scatter with no error bars) you can also change the colours after that you have plotted them, this sometimes is easier to perform.

import matplotlib.pyplot as plt
from random import randint
import numpy as np

#Let's generate some random X, Y data X = [ [frst group],[second group] ...]
X = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
Y = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
labels = range(1,len(X)+1)

fig = plt.figure()
ax = fig.add_subplot(111)
for x,y,lab in zip(X,Y,labels):
        ax.scatter(x,y,label=lab)

The only piece of code that you need:

#Now this is actually the code that you need, an easy fix your colors just cut and paste not you need ax.
colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired  
colorst = [colormap(i) for i in np.linspace(0, 0.9,len(ax.collections))]       
for t,j1 in enumerate(ax.collections):
    j1.set_color(colorst[t])


ax.legend(fontsize='small')

The output gives you differnent colors even when you have many different scatter plots in the same subplot.

I would suggest using the members of string, but with an explicit encoding:

byte[] bytes = text.getBytes("UTF-8");
String text = new String(bytes, "UTF-8");

By using an explicit encoding (and one which supports all of Unicode) you avoid the problems of just calling text.getBytes() etc:

• You're explicitly using a specific encoding, so you know which encoding to use later, rather than relying on the platform default.
• You know it will support all of Unicode (as opposed to, say, ISO-Latin-1).

EDIT: Even though UTF-8 is the default encoding on Android, I'd definitely be explicit about this. For example, this question only says "in Java or Android" - so it's entirely possible that the code will end up being used on other platforms.

Basically given that the normal Java platform can have different default encodings, I think it's best to be absolutely explicit. I've seen way too many people using the default encoding and losing data to take that risk.

EDIT: In my haste I forgot to mention that you don't have to use the encoding's name - you can use a Charset instead. Using Guava I'd really use:

byte[] bytes = text.getBytes(Charsets.UTF_8);
String text = new String(bytes, Charsets.UTF_8);

It means to interpret the string literally (that is, you cannot escape any characters within the string if you use the @ prefix). It enhances readability in cases where it can be used.

For example, if you were working with a UNC path, this:

@"\\servername\share\folder"

is nicer than this:

"\\\\servername\\share\\folder"

Use the built in type cast functionality, simply type

$realArray = (array)$stdClass;

You can also use a combination of cat and paste0

cat(paste0("File not supplied.\n", "Usage: ./program F=filename"))

I find this to be more useful when incorporating variables into the printout. For example:

file <- "myfile.txt"
cat(paste0("File not supplied.\n", "Usage: ./program F=", file))

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

I explain this to users by comparing Perforce changelists to a stack (from data structures).

Backing out removes one item from anywhere in the stack.

Rolling back removes n items from the top of the stack.

** 2019 Answer **

In a normal situation display:none doesn't prevent the image to be downloaded

/*will be downloaded*/

#element1 {
    display: none;
    background-image: url('https://picsum.photos/id/237/100');
}

But if an ancestor element has display:none then the descendant's images will not be downloaded

/* Markup */

<div id="father">
    <div id="son"></div>
</div>


/* Styles */

#father {
    display: none;
}

/* #son will not be downloaded because the #father div has display:none; */

#son {
    background-image: url('https://picsum.photos/id/234/500');
}

Other situations that prevent the image to be downloaded:

1- The target element doesn't exist

/* never will be downloaded because the target element doesn't exist */

#element-dont-exist {
    background-image: url('https://picsum.photos/id/240/400');
}

2- Two equal classes loading different images

/* The first image of #element2 will never be downloaded because the other #element2 class */

#element2 {
    background-image: url('https://picsum.photos/id/238/200');
}

/* The second image of #element2 will be downloaded */

#element2 {
    background-image: url('https://picsum.photos/id/239/300');
}

I finally got it:

ObjectMapper objectMapper = new ObjectMapper();
TypeFactory typeFactory = objectMapper.getTypeFactory();
List<SomeClass> someClassList = objectMapper.readValue(jsonString, typeFactory.constructCollectionType(List.class, SomeClass.class));

This can be done by using a pointer, and allocating memory on the heap using malloc. Note that there is no way to later ask how big that memory block is. You have to keep track of the array size yourself.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char** argv)
{
  /* declare a pointer do an integer */
  int *data; 
  /* we also have to keep track of how big our array is - I use 50 as an example*/
  const int datacount = 50;
  data = malloc(sizeof(int) * datacount); /* allocate memory for 50 int's */
  if (!data) { /* If data == 0 after the call to malloc, allocation failed for some reason */
    perror("Error allocating memory");
    abort();
  }
  /* at this point, we know that data points to a valid block of memory.
     Remember, however, that this memory is not initialized in any way -- it contains garbage.
     Let's start by clearing it. */
  memset(data, 0, sizeof(int)*datacount);
  /* now our array contains all zeroes. */
  data[0] = 1;
  data[2] = 15;
  data[49] = 66; /* the last element in our array, since we start counting from 0 */
  /* Loop through the array, printing out the values (mostly zeroes, but even so) */
  for(int i = 0; i < datacount; ++i) {
    printf("Element %d: %d\n", i, data[i]);
  }
}

That's it. What follows is a more involved explanation of why this works :)

I don't know how well you know C pointers, but array access in C (like array[2]) is actually a shorthand for accessing memory via a pointer. To access the memory pointed to by data, you write *data. This is known as dereferencing the pointer. Since data is of type int *, then *data is of type int. Now to an important piece of information: (data + 2) means "add the byte size of 2 ints to the adress pointed to by data".

An array in C is just a sequence of values in adjacent memory. array[1] is just next to array[0]. So when we allocate a big block of memory and want to use it as an array, we need an easy way of getting the direct adress to every element inside. Luckily, C lets us use the array notation on pointers as well. data[0] means the same thing as *(data+0), namely "access the memory pointed to by data". data[2] means *(data+2), and accesses the third int in the memory block.

you can use this trick to run tomcat using cmd and directly by tomcat bin folder.

1. set the path of jdk.

2.

To set path. go to Desktop and right click on computer icon. Click the Properties

go to Advance System Settings.

then Click Advance to Environment variables.

Click new and set path AS,

in the column Variable name=JAVA_HOME

Variable Value=C:\Program Files\Java\jdk1.6.0_19

Click ok ok.

now path is stetted.

3.

Go to tomcat folder where you installed the tomcat. go to bin folder. there are two window batch files.

1.Startup

2.Shutdown.

By using cmd if you installed the tomcate in D Drive

type on cmd screen

1. D:

2. Cd tomcat\bin then type Startup.

4. By clicking them you can start and stop the tomcat.

5.

Final step.

if you start and want to check it.

open a Browser in URL bar type.

**HTTP://localhost:8080/**

The docker logs command will show you the output a container is generating when you don't run it interactively. This is likely to include the error message.

docker logs --tail 50 --follow --timestamps mediawiki_web_1

You can also run a fresh container in the foreground with docker run -ti <your_wiki_image> to see what that does. You may need to map some config from your docker-compose yml to the docker command.

I would guess that attaching to the media wiki process caused a crash which has corrupted something in your data.

OUTPUT

Make sure you added permission to write data in memory

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Without importing math // using basic envionment:

a) method / class method

def ceil(fl): 
  return int(fl) + (1 if fl-int(fl) else 0)

def ceil(self, fl): 
  return int(fl) + (1 if fl-int(fl) else 0)

b) lambda:

ceil = lambda fl:int(fl)+(1 if fl-int(fl) else 0)

If you used [STAThread] to the main entry of your application and still get the error you may need to make a Thread-Safe call to the control... something like below. In my case with the same problem the following solution worked!

Private void YourFunc(..)

    if (this.InvokeRequired)
    {
        Invoke(new MethodInvoker(delegate()
        {
           // Call your method YourFunc(..);
        }));
    }
    else
    {
        ///

Every method in HtmlHelper class has a twin with For suffix. Html.Hidden takes a string as an argument that you must provide but Html.HiddenFor takes an Expression that if you view is a strongly typed view you can benefit from this and feed that method a lambda expression like this

o=>o.SomeProperty 

instead of "SomeProperty" in the case of using Html.Hidden method.

Since the other answers explained how to do it without actually explaining why it works:

When the switch executes, it finds the first matching case statement and then executes each line of code after the switch until it hits either a break statement or the end of the switch (or a return statement to leave the entire containing function). When you deliberately omit the break so that code under the next case gets executed too that's called a fall-through. So for the OP's requirement:

switch (pageid) {
   case "listing-page":
   case "home-page":
      alert("hello");
      break;

   case "details-page":
      alert("goodbye");
      break;
} 

Forgetting to include break statements is a fairly common coding mistake and is the first thing you should look for if your switch isn't working the way you expected. For that reason some people like to put a comment in to say "fall through" to make it clear when break statements have been omitted on purpose. I do that in the following example since it is a bit more complicated and shows how some cases can include code to execute before they fall-through:

switch (someVar) {
   case 1:
      someFunction();
      alert("It was 1");
      // fall through
   case 2:
      alert("The 2 case");
      // fall through
   case 3:
      // fall through
   case 4:
      // fall through
   case 5:
      alert("The 5 case");
      // fall through
   case 6:
      alert("The 6 case");
      break;

   case 7:
      alert("Something else");
      break;

   case 8:
      // fall through
   default:
      alert("The end");
      break;
}

You can also (optionally) include a default case, which will be executed if none of the other cases match - if you don't include a default and no cases match then nothing happens. You can (optionally) fall through to the default case.

So in my second example if someVar is 1 it would call someFunction() and then you would see four alerts as it falls through multiple cases some of which have alerts under them. Is someVar is 3, 4 or 5 you'd see two alerts. If someVar is 7 you'd see "Something else" and if it is 8 or any other value you'd see "The end".

This works for me:

java.util.Date d = new SimpleDateFormat("yyyy-MM-dd").parse(localDate.toString());

https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html#toString--

Try this:

1. Uncomment the following line in /etc/default/docker DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
2. Restart the Docker service sudo service docker restart
3. Delete any images which have cached the invalid DNS settings.
4. Build again and the problem should be solved.

From this question.

here's the way I've used, it's working for negative number

First, create MinMaxFIlter.java class with the following code :

import android.text.InputFilter;
import android.text.Spanned;
import android.util.Log;

/**
* Created by 21 on 4/5/2016.
*/
public class MinMaxFilter implements InputFilter {

private double mIntMin, mIntMax;

public MinMaxFilter(double minValue, double maxValue) {
    this.mIntMin = minValue;
    this.mIntMax = maxValue;
}

public MinMaxFilter(String minValue, String maxValue) {
    this.mIntMin = Double.parseDouble(minValue);
    this.mIntMax = Double.parseDouble(maxValue);
}

@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
    try {
        Boolean isNeg = false;
        String provi = dest.toString() + source.toString();
        if("-".equals(provi.substring(0,1))){
            if(provi.length()>1) {
                provi = provi.substring(1, provi.length());
                isNeg = true;
            }
            else{
                if("".equals(source)){
                    return null;
                }
                return "-";
            }
        }

        double input = Double.parseDouble(provi); 
        if(isNeg){input = input * (-1);}

        if (isInRange(mIntMin, mIntMax, input)) {
            return null;
        }
    } catch (Exception nfe) {}
    return "";
}

private boolean isInRange(double a, double b, double c) {
    if((c>=a && c<=b)){
        return true;
    }
    else{
        return false;
    }
}
}

Then, create and set your filter to your edittext like this :

EditText edittext = new EditText(context);
editext.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED);
eInt.setFilters(new InputFilter[]{new MinMaxFilter(min, max)});

int* test();

but it would be "more C++" to use vectors:

std::vector< int > test();

EDIT
I'll clarify some point. Since you mentioned C++, I'll go with new[] and delete[] operators, but it's the same with malloc/free.

In the first case, you'll write something like:

int* test() {
    return new int[size_needed];
}

but it's not a nice idea because your function's client doesn't really know the size of the array you are returning, although the client can safely deallocate it with a call to delete[].

int* theArray = test();
for (size_t i; i < ???; ++i) { // I don't know what is the array size!
    // ...
}
delete[] theArray; // ok.

A better signature would be this one:

int* test(size_t& arraySize) {
    array_size = 10;
    return new int[array_size];
}

And your client code would now be:

size_t theSize = 0;
int* theArray = test(theSize);
for (size_t i; i < theSize; ++i) { // now I can safely iterate the array
    // ...
}
delete[] theArray; // still ok.

Since this is C++, std::vector<T> is a widely-used solution:

std::vector<int> test() {
    std::vector<int> vector(10);
    return vector;
}

Now you don't have to call delete[], since it will be handled by the object, and you can safely iterate it with:

std::vector<int> v = test();
std::vector<int>::iterator it = v.begin();
for (; it != v.end(); ++it) {
   // do your things
}

which is easier and safer.

I recommend WinDirStat.

I frequently use WinDirStat to create screen shots for user documentation of open folders and their contents.

It even uses the correct icons for Windows registered file types.

All I would say is missing is an option to display the files without their icons. I can live without it personally, since I am usually pasting the image into a paint program or Visio to edit it, but it would still be a useful feature.

@Gajus Kuizinas and @CodeHater are correct. Here i am just giving an example. While we are working with ng-if, if the assigned value is false then the whole html elements will be removed from DOM. and if assigned value is true, then the html elements will be visible on the DOM. And the scope will be different compared to the parent scope. But in case of ng-show, it wil just show and hide the elements based on the assigned value. But it always stays in the DOM. Only the visibility changes as per the assigned value.

http://plnkr.co/edit/3G0V9ivUzzc8kpLb1OQn?p=preview

Hope this example will help you in understanding the scopes. Try giving false values to ng-show and ng-if and check the DOM in console. Try entering the values in the input boxes and observe the difference.

<!DOCTYPE html>

Hello Plunker!

<input type="text" ng-model="data">
<div ng-show="true">
    <br/>ng-show=true :: <br/><input type="text" ng-model="data">
</div>
<div ng-if="true">
    <br/>ng-if=true :: <br/><input type="text" ng-model="data">

Iam using Catalina and use this mysql_secure_installation command and now works for me:

$ mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): << enter root here >>

i enter root as current password

OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

and do the rest

So I had the same problem because I wasn't in the right directory where my file was located. So when I ran javac Example.java (for me) it said it couldn't find it. But I needed to go to where my Example.java file was located. So I used the command cd and right after that the location of the file. That worked for me. Tell me if it helps! Thanks!

Today I needed to accomplish a similar task so I wrote up a gist to accomplish the task based on some research I did. I hope that someone will find this useful!

Best, Az

Just to add on to what @Zaph says in the comments.

I have the same problem as you, as to know, the array of String is not saved. Even though Apple bridges types such as String and NSString, I wasn't able to save an array of [String] neither of [AnyObject].

However an array of [NSString] works for me.

So your code could look like that :

var key = "keySave"

var array1: [NSString] = [NSString]()
array1.append("value 1")
array1.append("value 2")

//save
var defaults = NSUserDefaults.standardUserDefaults()
defaults.setObject(array1, forKey: key)
defaults.synchronize()

//read
if let testArray : AnyObject? = defaults.objectForKey(key) {
    var readArray : [NSString] = testArray! as [NSString]
}

Note that I created an array of NSString and not a dictionary. I didn't check if it works with a dictionary, but probably you will have to define the things as [NSString : NSString] to have it working.

EDIT

Re-reading your question and your title, you are talking of array of array. I think that as long as you stay with NSString, an array of array will work. However, if you think my answer is irrelevant, just let me know in the comments and I will remove it.

Description

Assuming i understand your question.

You can get the selected row using the DataGridView.SelectedRows Collection. If your DataGridView allows only one selected, have a look at my sample.

DataGridView.SelectedRows Gets the collection of rows selected by the user.

Sample

if (dataGridView1.SelectedRows.Count != 0)
{
    DataGridViewRow row = this.dataGridView1.SelectedRows[0];
    row.Cells["ColumnName"].Value
}

More Information

• MSDN - DataGridView.SelectedRows Property

Keep it simple

var someString = "a_b_c";
var newCharacter = "+";

var newString = someString.substring(0, someString.lastIndexOf('_')) + newCharacter + someString.substring(someString.lastIndexOf('_')+1);

How about using some Sass? Here's what I did to achieve something like this (although note that you have to create a Sass list for each of the data-attributes).

/*
  Iterate over list and use "data-social" to put in the appropriate background-image.
*/
$social: "fb", "twitter", "youtube";

@each $i in $social {
  [data-social="#{$i}"] {
    background: url('#{$image-path}/icons/#{$i}.svg') no-repeat 0 0;
    background-size: cover; // Only seems to work if placed below background property
  }
}

Essentially, you list all of your data attribute values. Then use Sass @each to iterate through and select all the data-attributes in the HTML. Then, bring in the iterator variable and have it match up to a filename.

Anyway, as I said, you have to list all of the values, then make sure that your filenames incorporate the values in your list.

For CentOS, run this: sudo yum install libXext libSM libXrender

For built-in types, you can use the TypeCode enumeration. Please note that GetType() is kind of slow, but probably not relevant in most situations.

switch (Type.GetTypeCode(someObject.GetType()))
{
    case TypeCode.Boolean:
        break;
    case TypeCode.Byte:
        break;
    case TypeCode.Char:
        break;
}

For custom types, you can create your own enumeration, and either an interface or a base class with abstract property or method...

Abstract class implementation of property

public enum FooTypes { FooFighter, AbbreviatedFool, Fubar, Fugu };
public abstract class Foo
{
    public abstract FooTypes FooType { get; }
}
public class FooFighter : Foo
{
    public override FooTypes FooType { get { return FooTypes.FooFighter; } }
}

Abstract class implementation of method

public enum FooTypes { FooFighter, AbbreviatedFool, Fubar, Fugu };
public abstract class Foo
{
    public abstract FooTypes GetFooType();
}

One of my coworkers just told me about this too: This has the advantage that you can use it for literally any type of object, not just ones that you define. It has the disadvantage of being a bit larger and slower.

First define a static class like this:

public static class TypeEnumerator
{
    public class TypeEnumeratorException : Exception
    {
        public Type unknownType { get; private set; }
        public TypeEnumeratorException(Type unknownType) : base()
        {
            this.unknownType = unknownType;
        }
    }
    public enum TypeEnumeratorTypes { _int, _string, _Foo, _TcpClient, };
    private static Dictionary<Type, TypeEnumeratorTypes> typeDict;
    static TypeEnumerator()
    {
        typeDict = new Dictionary<Type, TypeEnumeratorTypes>();
        typeDict[typeof(int)] = TypeEnumeratorTypes._int;
        typeDict[typeof(string)] = TypeEnumeratorTypes._string;
        typeDict[typeof(Foo)] = TypeEnumeratorTypes._Foo;
        typeDict[typeof(System.Net.Sockets.TcpClient)] = TypeEnumeratorTypes._TcpClient;
    }
    /// <summary>
    /// Throws NullReferenceException and TypeEnumeratorException</summary>
    /// <exception cref="System.NullReferenceException">NullReferenceException</exception>
    /// <exception cref="MyProject.TypeEnumerator.TypeEnumeratorException">TypeEnumeratorException</exception>
    public static TypeEnumeratorTypes EnumerateType(object theObject)
    {
        try
        {
            return typeDict[theObject.GetType()];
        }
        catch (KeyNotFoundException)
        {
            throw new TypeEnumeratorException(theObject.GetType());
        }
    }
}

And then you can use it like this:

switch (TypeEnumerator.EnumerateType(someObject))
{
    case TypeEnumerator.TypeEnumeratorTypes._int:
        break;
    case TypeEnumerator.TypeEnumeratorTypes._string:
        break;
}

LINQ Any() would do the job:

bool contains = myList.Any(s => s.Contains(pattern));

Any(), MSDN:

Determines whether any element of a sequence satisfies a condition

Android already has a dedicated class for this. Check DateUtils.isToday(long when)

That is how I make it work :

In Linux (Ubuntu 16.04)

sudo apt-get install default-jre
sudo apt-get install default-jdk
sudo R CMD javareconf

in R:

install.packages("rJava")

Have you looked at the EXIF data of the images? It may know the orientation of the camera when the picture was taken.

So the solution to the original problem is that you don't need both the "@see" and the "{@link...}" references on the same line. The "@link" tag is self-sufficient and, as noted, you can put it anywhere in the javadoc block. So you can mix the two approaches:

/**
 * some javadoc stuff
 * {@link com.my.package.Class#method()}
 * more stuff
 * @see com.my.package.AnotherClass
 */

You can use command ng serve -c dev for development environment ng serve -c prod for production environment

while building also same applies. You can use ng build -c dev for dev build

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

I'm using NodeJS and got the same error. Like the other answers, the problem was also because JQuery needed to be loaded before Bootstrap; however, because of the NodeJS characteristics, this change had to be aplied in the pipeline.js file.

The change in pipeline.js was like this:

var jsFilesToInject = [
  // Dependencies like jQuery, or Angular are brought in here
  'js/dependencies/angular.1.3.js',
  'js/dependencies/jquery.js',
  'js/dependencies/bootstrap.js',
  'js/dependencies/**/*.js',
];

I'm also using grunt to help, and it automatically changed the order in the main html page:

<!--SCRIPTS-->
  <script src="/js/dependencies/angular.1.3.js"></script>
  <script src="/js/dependencies/jquery.js"></script>
  <script src="/js/dependencies/bootstrap.js"></script>
  <!-- other dependencies -->
<!--SCRIPTS END-->

Hope it helps! You didn't said what your environment was, so I decided to post this answer.

If you need to change the path, add this after your .config in your app file. Then you can do $location.path('/sampleurl', false); to prevent reloading

app.run(['$route', '$rootScope', '$location', function ($route, $rootScope, $location) {
    var original = $location.path;
    $location.path = function (path, reload) {
        if (reload === false) {
            var lastRoute = $route.current;
            var un = $rootScope.$on('$locationChangeSuccess', function () {
                $route.current = lastRoute;
                un();
            });
        }
        return original.apply($location, [path]);
    };
}])

Credit goes to https://www.consolelog.io/angularjs-change-path-without-reloading for the most elegant solution I've found.

Implement in this way

String i="hi";
Intent i = new Intent(this, ActivityTwo.class);
//Create the bundle
Bundle b = new Bundle();
//Add your data to bundle
b.putString(“stuff”, i);
i.putExtras(b);
startActivity(i);

Begin that second activity, inside this class to utilize the Bundle values use this code

Bundle bundle = getIntent().getExtras();
String text= bundle.getString("stuff");

The innerHTML fetches content depending on the id/name and replaces them.

<!DOCTYPE html>_x000D_

<button type = "button"_x000D_
onclick="document.getElementById('demo').innerHTML = Date()"> <!--fetches the content with id demo and changes the innerHTML content to Date()-->_x000D_
Click for date_x000D_
</button>_x000D_
<h3 id = 'demo'>Before Button is clicked this content will be Displayed the inner content of h3 tag with id demo and once you click the button this will be replaced by the Date() ,which prints the current date and time </h3> _x000D_

When you click the button,the content in h3 will be replaced by innerHTML assignent i.e Date() .

With the class below you can make the suggestion of Donut "exception safe".

To remove the last character do as Mark Byers said

s = s.substring(0, s.length() - 1);

Additionally, another way to remove the characters you don't want would be to use the .replace(oldCharacter, newCharacter) method.

as in:

s = s.replace(",","");

and

s = s.replace(".","");

If you need to handle error messages using jQuery.AJAX you will need to modify the xhr function so the responseType is not being modified when an error happens.

So you will have to modify the responseType to "blob" only if it is a successful call:

$.ajax({
    ...
    xhr: function() {
        var xhr = new XMLHttpRequest();
        xhr.onreadystatechange = function() {
            if (xhr.readyState == 2) {
                if (xhr.status == 200) {
                    xhr.responseType = "blob";
                } else {
                    xhr.responseType = "text";
                }
            }
        };
        return xhr;
    },
    ...
    error: function(xhr, textStatus, errorThrown) {
        // Here you are able now to access to the property "responseText"
        // as you have the type set to "text" instead of "blob".
        console.error(xhr.responseText);
    },
    success: function(data) {
        console.log(data); // Here is "blob" type
    }
});

Note

If you debug and place a breakpoint at the point right after setting the xhr.responseType to "blob" you can note that if you try to get the value for responseText you will get the following message:

The value is only accessible if the object's 'responseType' is '' or 'text' (was 'blob').

Even i recently had the same query....some how none of the above mentioned setmaxzoom or else map:cameraZoom="13" did not work So i found that the depenedency which i used was old please make sure your dependency for google maps is correct this is the newest use this

compile 'com.google.android.gms:play-services:11.8.0' 

An ftl file could just have a series of html tags just as a JSP page or it can have freemarker template coding for representing the objects passed on from a controller java file.
But, its actual ability is to combine the contents of a java class and view/client side stuff(html/ JQuery/ javascript etc). It is quite similar to velocity. You could map a method or object of a class to a freemarker (.ftl) page and use it as if it is a variable or a functionality created in the very page.

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

No need for a 3rd party library. Use the nodejs url module to build a URL with query parameters:

const requestUrl = url.parse(url.format({
    protocol: 'https',
    hostname: 'yoursite.com',
    pathname: '/the/path',
    query: {
        key: value
    }
}));

Then make the request with the formatted url. requestUrl.path will include the query parameters.

const req = https.get({
    hostname: requestUrl.hostname,
    path: requestUrl.path,
}, (res) => {
   // ...
})

In this case it is just coding style.

Use of var is only necessary when dealing with anonymous types.
In other situations it's a matter of taste.

select COUNT(*)
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5

You can add a style.css, import this file after the bootstrap.css to override this code.

For example:

/* bootstrap.css */
* {
   font-size: 14px;
   line-height: 1.428;
}

/* style.css */
* {
   font-size: 16px;
   line-height: 2;
}

Don't change bootstrap.css directly for better maintenance of code.

This should help you

            flag = true;
            originalmap = $('#mainmap');

This is the way to iterate on this array:

foreach($hotels as $row) {
       foreach($row['rooms'] as $k) {
             echo $k['boards']['board_id'];
             echo $k['boards']['price'];
       }
}

You want to iterate on the hotels and the rooms (the ones with numeric indexes), because those seem to be the "collections" in this case. The other arrays only hold and group properties.

If a DLL is written in one of the .NET languages and if you only want to view what functions, there is a reference to this DLL in the project.

Then doubleclick the DLL in the references folder and then you will see what functions it has in the OBJECT EXPLORER window

If you would like to view the source code of that DLL file you can use a decompiler application such as .NET reflector. hope this helps you.

I use the filter solution above, for ie8. However.. In order to solve the freezing links problem , do also the following:

background: no-repeat center center fixed\0/; /* IE8 HACK */

This has solved the frozen links problem for me.

Url.Action() will get you the bare URL for most overloads of Html.ActionLink, but I think that the URL-from-lambda functionality is only available through Html.ActionLink so far. Hopefully they'll add a similar overload to Url.Action at some point.

Here's one working syntax for SQL Server 2017:

USE [<yourdb-name>]
GO

SELECT * INTO NEWTABLE 
FROM <table1-name>
UNION ALL
SELECT * FROM <table2-name>

For me - I just went here:

https://console.developers.google.com/apis/credentials

Then chose the right project; then choose the credential with the same ID shown in your console error message. When editing the credentials you can add multiple origins to the white list.

pretty sure you just want the plain old replace function. use like this:

myString.replace('username1','');

i suppose if you want to remove the trailing comma do this instead:

myString.replace('username1,','');

edit:

here is your site specific code:

jQuery("#post_like_list-510").text().replace(...) 

16kb is about right; if you're using gigabit ethernet, each packet could be 9kb in size.

Here is how I styled my colored buttons with an icon in the background

I used "background-color" property for the color and "background" property for the image.

  <style>
    .btn {
      display: inline-block;
      line-height: 1em;
      padding: .1em .3em .15em 2em
      border-radius: .2em;
      border: 1px solid #d8d8d8;

      background-color: #cccccc;
    }

    .thumb-up {
      background: url('/icons/thumb-up.png') no-repeat 3px center;
    }

    .thumb-down {
      background: url('/icons/thumb-down.png') no-repeat 3px center;
    }
  </style>

  <span class="btn thumb-up">Thumb up</span>
  <span class="btn thumb-down">Thumb down</span>

I've not used it, but SendKeys may do what you want.

Use SendKeys to send keystrokes and keystroke combinations to the active application. This class cannot be instantiated. To send a keystroke to a class and immediately continue with the flow of your program, use Send. To wait for any processes started by the keystroke, use SendWait.

System.Windows.Forms.SendKeys.Send("A");
System.Windows.Forms.SendKeys.Send("{ENTER}");

Microsoft has some more usage examples here.

To print all the ascii values from 0 to 255 using while loop.

#include<stdio.h>

int main(void)
{
    int a;
    a = 0;
    while (a <= 255)
    {
        printf("%d = %c\n", a, a);
        a++;
    }
    return 0;
}

MIME type of the CSV is text/csv according to RFC 4180.

There is no trigger to perform code when the app is deleted from the device. Access to the keychain is dependant on the provisioning profile that is used to sign the application. Therefore no other applications would be able to access this information in the keychain.

It does not help with you aim to remove the password in the keychain when the user deletes application from the device but it should give you some comfort that the password is not accessible (only from a re-install of the original application).

Here is another way to do it if you want to use ViewData:

@Html.Partial("~/PathToYourView.cshtml", null, new ViewDataDictionary { { "VariableName", "some value" } })

And to retrieve the passed in values:

@{
    string valuePassedIn = this.ViewData.ContainsKey("VariableName") ? this.ViewData["VariableName"].ToString() : string.Empty;
}

If you have a dictionary you can turn it into a pandas data frame with the following line of code:

pd.DataFrame({"key": d.keys(), "value": d.values()})

Just put this in the header of your PHP Page and it ill work without API:

header('Access-Control-Allow-Origin: *'); //allow everybody  

or

header('Access-Control-Allow-Origin: http://codesheet.org'); //allow just one domain 

or

$http_origin = $_SERVER['HTTP_ORIGIN'];  //allow multiple domains

$allowed_domains = array(
  'http://codesheet.org',
  'http://stackoverflow.com'
);

if (in_array($http_origin, $allowed_domains))
{  
    header("Access-Control-Allow-Origin: $http_origin");
}

String if the size is fixed and small and text if it is variable and big. This is kind of important because text is way bigger than strings. It contains a lot more kilobytes.

So for small fields always use string(varchar). Fields like. first_name, login, email, subject (of a article or post) and example of texts: content/body of a post or article. fields for paragraphs etc

String size 1 to 255 (default = 255)

Text size 1 to 4294967296 (default = 65536)2

You can also use ngrok: https://ngrok.com/. I use it all the time to have a public server running on my localhost. Hope this helps.

Another options which even provides your own custom domain for free are serveo.net and https://localtunnel.github.io/www/

For this and other kind of client detections I suggest this js library: http://hictech.github.io/navJs/tester/index.html

For your specific answer use:

navJS.isIOS() || navJS.isAndroid()

In most software that generates RSA private keys, including openssl's, the private key is represented as a PKCS#1 RSAPrivatekey object or some variant thereof:

A.1.2 RSA private key syntax

An RSA private key should be represented with the ASN.1 type
RSAPrivateKey:

  RSAPrivateKey ::= SEQUENCE {
      version           Version,
      modulus           INTEGER,  -- n
      publicExponent    INTEGER,  -- e
      privateExponent   INTEGER,  -- d
      prime1            INTEGER,  -- p
      prime2            INTEGER,  -- q
      exponent1         INTEGER,  -- d mod (p-1)
      exponent2         INTEGER,  -- d mod (q-1)
      coefficient       INTEGER,  -- (inverse of q) mod p
      otherPrimeInfos   OtherPrimeInfos OPTIONAL
  }

As you can see, this format has a number of fields including the modulus and public exponent and thus is a strict superset of the information in an RSA public key.

I solved the same problem of having to reset a form at its pristine state in Angular version 1.0.7 (no $setPristine method)

In my use case, the form, after being filled and submitted must disappear until it is again necessary for filling another record. So I made the show/hide effect by using ng-switch instead of ng-show. As I suspected, with ng-switch, the form DOM sub-tree is completely removed and later recreated. So the pristine state is automatically restored.

I like it because it is simple and clean but it may not be a fit for anybody's use case.

it may also imply some performance issues for big forms (?) In my situation I did not face this problem yet.

It's worth noting that if you go the jailbroken route, it's possible (likely?) that an iPhone OS update would kill your ability to run these apps. I'd go the official route and pay the $99 to get authorized. In addition to not having to worry about your apps being clobbered, you also get the opportunity (should you choose) to release your apps on the store.

In my case the problem was solved by appending the string cordova.system.library.2=com.android.support:support-v4:+ to platforms/android/project.properties file

Use this method to check the network state:

private void checkInternetConnection() {

    if (br == null) {

        br = new BroadcastReceiver() {

            @Override
            public void onReceive(Context context, Intent intent) {

                Bundle extras = intent.getExtras();

                NetworkInfo info = (NetworkInfo) extras
                        .getParcelable("networkInfo");

                State state = info.getState();
                Log.d("TEST Internet", info.toString() + " "
                        + state.toString());

                if (state == State.CONNECTED) {
                      Toast.makeText(getApplicationContext(), "Internet connection is on", Toast.LENGTH_LONG).show();

                } else {
                       Toast.makeText(getApplicationContext(), "Internet connection is Off", Toast.LENGTH_LONG).show();
                }

            }
        };

        final IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
        registerReceiver((BroadcastReceiver) br, intentFilter);
    }
}

remember to unregister service in onDestroy.

Cheers!!

you'll probably want to look into jquery-ui dialog. it's highly customizable and can be made to work exactly like lightbox/fancybox and supports everything you would need for a contact form from a regular link.

there is even an example with a form.

Use SemaphoreSlim.WaitAsync method.

 await mySemaphoreSlim.WaitAsync();
 try {
     await Stuff();
 } finally {
     mySemaphoreSlim.Release();
 }

From the Javadoc for Character#getNumericValue:

If the character does not have a numeric value, then -1 is returned. If the character has a numeric value that cannot be represented as a nonnegative integer (for example, a fractional value), then -2 is returned.

The character + does not have a numeric value, so you're getting -1.

Update:

The reason that primitive conversion is giving you 43 is that the the character '+' is encoded as the integer 43.

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

Do you mean this?

def perform(fun, *args):
    fun(*args)

def action1(args):
    # something

def action2(args):
    # something

perform(action1)
perform(action2, p)
perform(action3, p, r)

Install an interval:

<script type="text/javascript">    
    setInterval(page_refresh, 5*60000); //NOTE: period is passed in milliseconds
</script>

It will be supported in JDK 10. It's even possible to see it in action in the early access build.

The JEP 286:

Enhance the Java Language to extend type inference to declarations of local variables with initializers.

So now instead of writing:

List<> list = new ArrayList<String>();
Stream<> stream = myStream();

You write:

var list = new ArrayList<String>();
var stream = myStream();

Notes:

• var is now a reserved type name
• Java is still commitment to static typing!
• It can be only used in local variable declarations

If you want to give it a try without installing Java on your local system, I created a Docker image with JDK 10 installed on it:

modify your app's or module's build.gradle

android {
    defaultConfig {
        ...
        minSdkVersion 21 <----- *here
        targetSdkVersion 26
        multiDexEnabled true <------ *here
    }
    ...
}

According to official documentation

Multidex support for Android 5.0 and higher

Android 5.0 (API level 21) and higher uses a runtime called ART which natively supports loading multiple DEX files from APK files. ART performs pre-compilation at app install time which scans for classesN.dex files and compiles them into a single .oat file for execution by the Android device. Therefore, if your minSdkVersion is 21 or higher, you do not need the multidex support library.

For more information on the Android 5.0 runtime, read ART and Dalvik.

https://developer.android.com/studio/build/multidex

Use fabs() instead of abs(), it's the same but for floats instead of integers.

I would use XMLHTTP request to retrieve page content as much faster. Then it is easy enough to use querySelectorAll to apply a CSS class selector to grab by class name. Then you access the child elements by tag name and index.

Option Explicit
Public Sub GetInfo()
    Dim sResponse As String, html As HTMLDocument, elements As Object, i As Long

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", "https://www.hsbc.com/about-hsbc/leadership", False
        .setRequestHeader "If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"
        .send
        sResponse = StrConv(.responseBody, vbUnicode)
    End With
    Set html = New HTMLDocument
    With html
        .body.innerHTML = sResponse
        Set elements = .querySelectorAll(".profile-col1")
        For i = 0 To elements.Length - 1
            Debug.Print String(20, Chr$(61))
            Debug.Print elements.item(i).getElementsByTagName("a")(0).innerText
            Debug.Print elements.item(i).getElementsByTagName("p")(0).innerText
            Debug.Print elements.item(i).getElementsByTagName("p")(1).innerText
        Next
    End With
End Sub

When I was to get yesterday with just the date in the format Year/Month/Day I use:

$Variable = Get-Date((get-date ).AddDays(-1))  -Format "yyyy-MM-dd"

import os
import os.path
import shutil

You find your current directory:

d = os.getcwd() #Gets the current working directory

Then you change one directory up:

os.chdir("..") #Go up one directory from working directory

Then you can get a tupple/list of all the directories, for one directory up:

o = [os.path.join(d,o) for o in os.listdir(d) if os.path.isdir(os.path.join(d,o))] # Gets all directories in the folder as a tuple

Then you can search the tuple for the directory you want and open the file in that directory:

for item in o:
    if os.path.exists(item + '\\testfile.txt'):
    file = item + '\\testfile.txt'

Then you can do stuf with the full file path 'file'

If you know there are no sub-folders, something like this may be the easiest:

    Directory.GetFiles(folderName).ForEach(File.Delete)

If you use pooling (http client factory) or load balancing (eureka) mechanism with your RestTemplate, you will not have the luxury of creating a new RestTemplate per class. If you are calling more than one service you cannot use setErrorHandler because if would be globally used for all your requests.

In this case, catching the HttpStatusCodeException seems to be the better option.

The only other option you have is to define multiple RestTemplate instances using the @Qualifier annotation.

Also - but this is my own taste - I like my error handling snuggled tightly to my calls.

I use tabBarController and i have a few section in my tableview at every tab, so this is best solution for me.

extension UITableView {

    func scrollToTop(){

        for index in 0...numberOfSections - 1 {
            if numberOfSections > 0 && numberOfRows(inSection: index) > 0 {
                scrollToRow(at: IndexPath(row: 0, section: index), at: .top, animated: true)
                break
            }

            if index == numberOfSections - 1 {
                setContentOffset(.zero, animated: true)
                break
            }
        }

    }

}

Well, at the risk of making things too easy...

for (var member in myObject) delete myObject[member];

...would seem to be pretty effective in cleaning the object in one line of code with a minimum of scary brackets. All members will be truly deleted instead of left as garbage.

Obviously if you want to delete the object itself, you'll still have to do a separate delete() for that.

As mentioned above using unpack function of struct is a good way. If you want to implement your own function there is an another solution:

def bytes_to_int(bytes):
    result = 0
    for b in bytes:
        result = result * 256 + int(b)
return result

As per node js doc process.cwd()

cwd is a method of global object process, returns a string value which is the current working directory of the Node.js process.

As per node js doc __dirname

The directory name of current script as a string value. __dirname is not actually a global but rather local to each module.

Let me explain with example,

suppose we have a main.js file resides inside C:/Project/main.js and running node main.js both these values return same file

or simply with following folder structure

Project 
+-- main.js
+--lib
   +-- script.js

main.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

suppose we have another file script.js files inside a sub directory of project ie C:/Project/lib/script.js and running node main.js which require script.js

main.js

require('./lib/script.js')
console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

script.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project\lib
console.log(__dirname===process.cwd())
// false

Node * merge_sort(Node *a, Node *b){
   Node *result = NULL;
   if(a ==  NULL)
      return b;
   else if(b == NULL)
      return a;

  /* For the first node, we would set the result to either a or b */
    if(a->data <= b->data){
       result = a;
    /* Result's next will point to smaller one in lists 
       starting at a->next  and b */
      result->next = merge_sort(a->next,b);
    }
    else {
      result = b;
     /*Result's next will point to smaller one in lists 
       starting at a and b->next */
       result->next = merge_sort(a,b->next);
    }
    return result;
 }

There isn't a single answer for this.

Encryption will always consume more CPU. This can be offloaded to dedicated hardware in many cases, and the cost will vary by algorithm selected. 3des is more expensive than AES, for example. Some algorithms are more expensive for the encrypter than the decryptor. Some have the opposite cost.

More expensive than the bulk crypto is handshake cost. New connections will consume much more CPU. This can be reduced with session resumption, at the cost of keeping old session secrets around until they expire. This means that small requests from a client that doesn't come back for more are the most expensive.

For cross internet traffic you may not notice this cost in your data rate, because the bandwidth available is too low. But you will certainly notice it in CPU usage on a busy server.

When Javascript is executed in a browser, all your code is surrounded by a with statement, like so:

with (window) {
    //Your code
}

More info on with - MDN

Since var declares a variable in the current scope , there is no difference between declaring var inside window and not declaring it at all.

The difference comes when you're not directly inside the window, e.g. inside a function or inside a block.

Using var lets you hide external variables that have the same name. In this way you can simulate a "private" variable, but that's another topic.

A rule of thumb is to always use var, because otherwise you run the risk of introducing subtle bugs.

EDIT: After the critiques I received, I would like to emphasize the following:

• var declares a variable in the current scope
• The global scope is window
• Not using var implicitly declares var in the global scope (window)
• Declaring a variable in the global scope (window) using var is the same as omitting it.
• Declaring a variable in scopes different from window using var is not the same thing as declaring a variable without var
• Always declare var explicitly because it's good practice

This could be useful when implementing multiprocessing and parallel/ distributed computing in Python.

YouTube tutorial on using techila package

Techila is a distributed computing middleware, which integrates directly with Python using the techila package. The peach function in the package can be useful in parallelizing loop structures. (Following code snippet is from the Techila Community Forums)

techila.peach(funcname = 'theheavyalgorithm', # Function that will be called on the compute nodes/ Workers
    files = 'theheavyalgorithm.py', # Python-file that will be sourced on Workers
    jobs = jobcount # Number of Jobs in the Project
    )

I guess what you want is your index servlet to act as the welcome page, so change to:

<welcome-file-list>
   <welcome-file>index</welcome-file>
</welcome-file-list>

So that the index servlet will be used. Note, you'll need a servlet spec 2.4 container to be able to do this.

Note also, @BalusC gets my vote, for your index servlet on its own is superfluous.

If we are using apache commons logging wrapper on top of log4j, then we need to have both the jars available in classpath. Also, commons-logging.properties and log4j.properties/xml should be available in classpath.

We can also pass implementation class and log4j.properties name as JAVA_OPTS either using -Dorg.apache.commons.logging.Log=<logging implementation class name> -Dlog4j.configuration=<file:location of log4j.properties/xml file>. Same can be done via setting JAVA_OPTS in case of app/web server.

It will help to externalize properties which can be changed in deployment.

It's a nightmare since each browser/device handles it differently.

Favicon generator helps me a lot for those applications where we need to cover the most possible scenarios.

https://realfavicongenerator.net/

You just need a png image 260px x 260px (at least) and from there the generator will create all references you need within your web page.

You just need to add this references and images to your application.

Just do this way:-

$('ul li').on('click', function(e) {
    alert($(this).index()); 
});

OR

$('ul li').click(function() {
    alert($(this).index());
});

Nothing wrong with straight up recursion for this task, and if you need a version that works with strings, this might fit your needs:

combinations = []

def combine(terms, accum):
    last = (len(terms) == 1)
    n = len(terms[0])
    for i in range(n):
        item = accum + terms[0][i]
        if last:
            combinations.append(item)
        else:
            combine(terms[1:], item)


>>> a = [['ab','cd','ef'],['12','34','56']]
>>> combine(a, '')
>>> print(combinations)
['ab12', 'ab34', 'ab56', 'cd12', 'cd34', 'cd56', 'ef12', 'ef34', 'ef56']

I know a lot of answers has been given but in my case I added web.{Environment}.config versions in my project and when publishing for a particular environment the value gets replaced.

For example, for Staging (web.Staging.config)

<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
    <location>
        <system.webServer>
            <aspNetCore>
                <environmentVariables xdt:Transform="InsertIfMissing">
                    <environmentVariable name="ASPNETCORE_ENVIRONMENT"
                                         value="Staging"
                                         xdt:Locator="Match(name)"
                                         xdt:Transform="InsertIfMissing" />
                </environmentVariables>
            </aspNetCore>
        </system.webServer>
    </location>
</configuration>

For Release or Production I will do this (web.Release.config)

<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
    <location>
        <system.webServer>
            <aspNetCore>
                <environmentVariables xdt:Transform="InsertIfMissing">
                    <environmentVariable name="ASPNETCORE_ENVIRONMENT"
                                         value="Release"
                                         xdt:Locator="Match(name)"
                                         xdt:Transform="InsertIfMissing" />
                </environmentVariables>
            </aspNetCore>
        </system.webServer>
    </location>
</configuration>

Then when publishing I will choose or set the environment name. And this will replace the value of the environment in the eventual web.config file.

There should be only one localhost defined, check sites-enabled or nginx.conf.

For ng-click working properly you need define your controller after angularjs script binding and use it via $scope.

you can also try

var query = from p in list
            where p.Age > 18
            select p;

For a checked exception:

public class MyCustomException extends Exception { }

Technically, anything that extends Throwable can be an thrown, but exceptions are generally extensions of the Exception class so that they're checked exceptions (except RuntimeException or classes based on it, which are not checked), as opposed to the other common type of throwable, Errors which usually are not something designed to be gracefully handled beyond the JVM internals.

You can also make exceptions non-public, but then you can only use them in the package that defines them, as opposed to across packages.

As far as throwing/catching custom exceptions, it works just like the built-in ones - throw via

throw new MyCustomException()

and catch via

catch (MyCustomException e) { }

Your best bet is to review the Java Swing tutorials, specifically the tutorial on Buttons.

The short code snippet is:

jBtnDrawCircle.addActionListener( /*class that implements ActionListener*/ );

1. Press the Apps menu button on your Android mobile phone device. It will display icons of all the apps installed on your mobile phone device. Press Settings.

2. Press Apps. (Pressing on Apps button will list down all the apps installed on your mobile phone.

3. Browse the Apps list and press on the app called "Launcher 3". (Launcher 3 is an app and it will be listed in the App list whenever you access Settings > Apps in your android phone).

4. Pressing on the "Launcher 3" app will open the "App info screen" which will show some details pertaining to that app. On this App info screen, you will find buttons like "Force Stop", "Uninstall", "Clear Data" and "Clear Cache" etc.

5. In Android Marshmallow (i.e. Android 6.0) choose Settings > Apps > Launcher3 > STORAGE. Press "Clear Cache". If this fails, press "Clear data". This will eventually restore functionality, but all custom shortcuts will be lost.

Restart the phone and its done. All the home screens along with app shortcuts will appear again and your mobile phone is at your service again.

I hope it explains well on how to solve the launcher problem in Android. Worked for me.

when I have problem with WAMP apache , I use this code for find which program is using port 80.

netstat -o -n -a | findstr 0.0:80

3068 is PID, so I can find it from task manager and stop that process.

You can do this in pretty concise way using ResponseEntity like this:

  @GetMapping
  ResponseEntity<Void> redirect() {
    return ResponseEntity.status(HttpStatus.FOUND)
        .location(URI.create("http://www.yahoo.com"))
        .build();
  }

If without '0x' prefix:

'{0:x}'.format(int(dec))

else use built-in hex() funtion.

python -m pip install opencv-python

which will install opencv based on your current python

Same problem but using SourceTree (or any other git client). I'm adding my answer as none of the answers correspond to my case.

Changing the branch from "develop" to "main" changes the actual files and subfolders of your local folder. It can happen that a folder that didn't exist in the "master" are not completely erased and windows believe you only lost your access rights (even if you're the admin). When merging from main to develop, the git client tries to access the folder. Without access rights, it returns the mentioned error.

• Switching from one branch to the latest can fix the problem, and then back to master (double check if the folders/files are actually locally deleted).
• Closing the client and/or your editor does not fix the problem!
• Reboot helps but is a waste of time (IMHO)

try this:

.nav {
  font-family: monospace;
}

While Ryan is correct, the solution can be much simpler based on what is known about the source of the randomness. To re-state the problem:

• There is a source of randomness, outputting integer numbers in range [0, MAX) with uniform distribution.
• The goal is to produce uniformly distributed random integer numbers in range [rmin, rmax] where 0 <= rmin < rmax < MAX.

In my experience, if the number of bins (or "boxes") is significantly smaller than the range of the original numbers, and the original source is cryptographically strong - there is no need to go through all that rigamarole, and simple modulo division would suffice (like output = rnd.next() % (rmax+1), if rmin == 0), and produce random numbers that are distributed uniformly "enough", and without any loss of speed. The key factor is the randomness source (i.e., kids, don't try this at home with rand()).

Here's an example/proof of how it works in practice. I wanted to generate random numbers from 1 to 22, having a cryptographically strong source that produced random bytes (based on Intel RDRAND). The results are:

Rnd distribution test (22 boxes, numbers of entries in each box):     
 1: 409443    4.55%
 2: 408736    4.54%
 3: 408557    4.54%
 4: 409125    4.55%
 5: 408812    4.54%
 6: 409418    4.55%
 7: 408365    4.54%
 8: 407992    4.53%
 9: 409262    4.55%
10: 408112    4.53%
11: 409995    4.56%
12: 409810    4.55%
13: 409638    4.55%
14: 408905    4.54%
15: 408484    4.54%
16: 408211    4.54%
17: 409773    4.55%
18: 409597    4.55%
19: 409727    4.55%
20: 409062    4.55%
21: 409634    4.55%
22: 409342    4.55%   
total: 100.00%

This is as close to uniform as I need for my purpose (fair dice throw, generating cryptographically strong codebooks for WWII cipher machines such as http://users.telenet.be/d.rijmenants/en/kl-7sim.htm, etc). The output does not show any appreciable bias.

Here's the source of cryptographically strong (true) random number generator: Intel Digital Random Number Generator and a sample code that produces 64-bit (unsigned) random numbers.

int rdrand64_step(unsigned long long int *therand)
{
  unsigned long long int foo;
  int cf_error_status;

  asm("rdrand %%rax; \
        mov $1,%%edx; \
        cmovae %%rax,%%rdx; \
        mov %%edx,%1; \
        mov %%rax, %0;":"=r"(foo),"=r"(cf_error_status)::"%rax","%rdx");
        *therand = foo;
  return cf_error_status;
}

I compiled it on Mac OS X with clang-6.0.1 (straight), and with gcc-4.8.3 using "-Wa,q" flag (because GAS does not support these new instructions).

For a popup javascript is required. Put this in your header:

<script>
function myFunction()
{
alert("I am an alert box!"); // this is the message in ""
}
</script>

And this in your body:

<input type="button" onclick="myFunction()" value="Show alert box">

When the button is pressed a box pops up with the message set in the header.

This can be put in any html or php file without the php tags.

-----EDIT-----

To display it using php try this:

<?php echo '<script>myfunction()</script>'; ?>

It may not be 100% correct but the principle is the same.

To display different messages you can either create lots of functions or you can pass a variable in to the function when you call it.

Here is the simple API-less "readable script" version I use for pre-padding a string. (Simple, Readable, and Adjustable).

while(str.length() < desired_length)
  str = '0'+str;

<input type="radio" name="ans3" value="help"> 
<input type="radio" name="ans3" value="help1">
<input type="radio" name="ans3" value="help2">

<input type="radio" name="ans2" value="test"> 
<input type="radio" name="ans2" value="test1">
<input type="radio" name="ans2" value="test2">

<script type="text/javascript">
  var ans3 = jq("input[name='ans3']:checked").val()
  var ans2 = jq("input[name='ans2']:checked").val()
</script>

I used the Bootstrap 4 buttons plugin (https://getbootstrap.com/docs/4.0/components/buttons/#button-plugin) and added the class rounded to the labels and the class mx-1 to the middle button to achieve the desired look and feel of separate radio buttons. Using the class btn-toolbar made the radio button circles appear for me which is not what I wanted. Hope this helps someone.

        <div class="btn-group btn-group-toggle" data-toggle="buttons">
            <label class="btn btn-secondary active rounded">
                <input type="radio" name="options" id="option1" autocomplete="off" checked> Active
            </label>
            <label class="btn btn-secondary rounded mx-1">
                <input type="radio" name="options" id="option2" autocomplete="off"> Radio
            </label>
            <label class="btn btn-secondary rounded">
                <input type="radio" name="options" id="option3" autocomplete="off"> Radio
            </label>
        </div>
