Since you're returning a string as JSON, that string will include the opening and closing quotes in the raw response. So your response should probably look like:

"abc123XYZ=="

or whatever...You can try confirming this with Fiddler.

My guess is that the result.Content is the raw string, including the quotes. If that's the case, then result.Content will need to be deserialized before you can use it.

I am using this:

loading = ProgressDialog.show(example.this,"",null, true, true);

Go from this:

config.Routes.MapHttpRoute("API Default", "api/{controller}/{id}",
            new { id = RouteParameter.Optional });

To this:

config.Routes.MapHttpRoute("API Default", "api/{controller}/{action}/{id}",
            new { id = RouteParameter.Optional });

Hence, you can now specify which action (method) you want to send your HTTP request to.

posting to "http://localhost:8383/api/Command/PostCreateUser" invokes:

public bool PostCreateUser(CreateUserCommand command)
{
    //* ... *//
    return true;
}

and posting to "http://localhost:8383/api/Command/PostMakeBooking" invokes:

public bool PostMakeBooking(MakeBookingCommand command)
{
    //* ... *//
    return true;
}

I tried this in a self hosted WEB API service application and it works like a charm :)

When you are using GET Method the contract must be this.

[WebGet(UriTemplate = "/", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
List<User> Get();

with this we have a json without the boot parameter

Selenium doesn't support opening new tabs. It only supports opening new windows. For all intents and purposes a new window is functionally equivalent to a new tab anyway.

There are various hacks to work around the issue, but they are going to cause you other problems in the long run.

From https://stackoverflow.com/a/2434094/848072. You need a default constructor for T class.

import java.lang.reflect.ParameterizedType;

class Foo {

  public bar() {
    ParameterizedType superClass = (ParameterizedType) getClass().getGenericSuperclass();
    Class type = (Class) superClass.getActualTypeArguments()[0];
    try {
      T t = type.newInstance();
      //Do whatever with t
    } catch (Exception e) {
      // Oops, no default constructor
      throw new RuntimeException(e);
    } 
  }
}

It sounds like you're not asking for a general-purpose memoization decorator (i.e., you're not interested in the general case where you want to cache return values for different argument values). That is, you'd like to have this:

x = obj.name  # expensive
y = obj.name  # cheap

while a general-purpose memoization decorator would give you this:

x = obj.name()  # expensive
y = obj.name()  # cheap

I submit that the method-call syntax is better style, because it suggests the possibility of expensive computation while the property syntax suggests a quick lookup.

[Update: The class-based memoization decorator I had linked to and quoted here previously doesn't work for methods. I've replaced it with a decorator function.] If you're willing to use a general-purpose memoization decorator, here's a simple one:

def memoize(function):
  memo = {}
  def wrapper(*args):
    if args in memo:
      return memo[args]
    else:
      rv = function(*args)
      memo[args] = rv
      return rv
  return wrapper

Example usage:

@memoize
def fibonacci(n):
  if n < 2: return n
  return fibonacci(n - 1) + fibonacci(n - 2)

Another memoization decorator with a limit on the cache size can be found here.

You can't create tags with Dockerfiles but you can create multiple tags on your images via the command line.

Use this to list your image ids:

$ docker images

Then tag away:

$ docker tag 9f676bd305a4 ubuntu:13.10
$ docker tag 9f676bd305a4 ubuntu:saucy
$ docker tag eb601b8965b8 ubuntu:raring
...

round(number, 1)

So here's the complete walkthrough:

1. Create new Console Application project (e.g. MyService)
2. Add two library references: System.ServiceProcess and System.Configuration.Install
3. Add the three files printed below
4. Build the project and run "InstallUtil.exe c:\path\to\MyService.exe"
5. Now you should see MyService on the service list (run services.msc)

*InstallUtil.exe can be usually found here: C:\windows\Microsoft.NET\Framework\v4.0.30319\InstallUtil.ex??e

List of XML and HTML character entity references:

In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference. This article lists the character entity references that are valid in HTML and XML documents.

That article lists the following five predefined XML entities:

quot  "
amp   &
apos  '
lt    <
gt    >

Like this.

import java.util.Date;
import java.util.GregorianCalendar;

/**
 * DateDiff -- compute the difference between two dates.
 */
public class DateDiff {
  public static void main(String[] av) {
    /** The date at the end of the last century */
    Date d1 = new GregorianCalendar(2000, 11, 31, 23, 59).getTime();

    /** Today's date */
    Date today = new Date();

    // Get msec from each, and subtract.
    long diff = today.getTime() - d1.getTime();

    System.out.println("The 21st century (up to " + today + ") is "
        + (diff / (1000 * 60 * 60 * 24)) + " days old.");
  }

}

Here is an article on Java date arithmetic.

Advantage of ScheduledExecutorService over Timer

I wish to offer you an alternative to Timer using - ScheduledThreadPoolExecutor, an implementation of the ScheduledExecutorService interface. It has some advantages over the Timer class, according to "Java in Concurrency":

A Timer creates only a single thread for executing timer tasks. If a timer task takes too long to run, the timing accuracy of other TimerTask can suffer. If a recurring TimerTask is scheduled to run every 10 ms and another Timer-Task takes 40 ms to run, the recurring task either (depending on whether it was scheduled at fixed rate or fixed delay) gets called four times in rapid succession after the long-running task completes, or "misses" four invocations completely. Scheduled thread pools address this limitation by letting you provide multiple threads for executing deferred and periodic tasks.

Another problem with Timer is that it behaves poorly if a TimerTask throws an unchecked exception. Also, called "thread leakage"

The Timer thread doesn't catch the exception, so an unchecked exception thrown from a TimerTask terminates the timer thread. Timer also doesn't resurrect the thread in this situation; instead, it erroneously assumes the entire Timer was cancelled. In this case, TimerTasks that are already scheduled but not yet executed are never run, and new tasks cannot be scheduled.

And another recommendation if you need to build your own scheduling service, you may still be able to take advantage of the library by using a DelayQueue, a BlockingQueue implementation that provides the scheduling functionality of ScheduledThreadPoolExecutor. A DelayQueue manages a collection of Delayed objects. A Delayed has a delay time associated with it: DelayQueue lets you take an element only if its delay has expired. Objects are returned from a DelayQueue ordered by the time associated with their delay.

Some addition to previous comments: 'firstboot' won't be available until you run 'mount_root' command.

So here is a full recap of what needs to be done. All manipulations I did on Windows 8.1.

• Enter Failsafe mode (hold the reset button on boot for a few seconds)
• Assign a static IP address, 192.168.1.2, to your PC. Example of a command: netsh interface ip set address name="Ethernet" static 192.168.1.2 255.255.255.0 192.168.1.1
• Connect to address 192.168.1.1 from telnet (I use PuTTY) and login/password isn't required).
• Run 'mount_root' (otherwise 'firstboot' won't be available).
• Run 'firstboot' to reset.
• Run 'reboot -f' to reboot.

Now you can enter to the router console from a browser. Also don't forget to return your PC from static to DHCP address assignment. Example: netsh interface ip set address name="Ethernet" source=dhcp

As everyone else has mentioned, the first task is to add the certificate to the Trusted Root Authority.

There is a custom exe (selfssl.exe) which will create a certificate and allow you to specify the Issued to: value (the URL). This means Internet explorer will validate the issued to url with the custom intranet url.

Make sure you restart Internet Explorer to refresh changes.

SHGetKnownFolderPath:

Retrieves the full path of a known folder identified by the folder's KNOWNFOLDERID.

And, FOLDERID_CommonStartup:

Default Path %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\StartUp

There are also managed equivalents, but you haven't told us what you're programming in.

it solved me by adjusting code from @Connor Cushion Mulhall by

iframe, object, embed {_x000D_
  width: 100%;_x000D_
  display: block !important;_x000D_
}

public void actionPerformed(ActionEvent arg0)
{
    if (arg0.getSource()==clearButton)
    {
        enterText.setText(null);
        enterText.grabFocus();  //Places flashing cursor on text box        
    }       
}

If you split the filename on underscore and dot, you get an array of 3 strings. Join the first and third string, i.e. with index 0 and 2

$x = '237801_201011221155.xml' 
( $x.split('_.')[0] , $x.split('_.')[2] ) -join '.' 

Another way to do the same thing:

'237801_201011221155.xml'.split('_.')[0,2] -join '.'

When I had this problem, I installed 'Remote Tools for Visual Studio 2015' from MSDN. I attached my local VS to the server to debug.

I appreciate that some folks may not have the ability to either install on or access other servers, but I thought I'd throw it out there as an option.

I just want to add something to these great answers. If your DOM element ins't loading in time. You can still set the value.

let Ctrl = $('#mySelectElement'); ... Ctrl.attr('value', myValue);

after that most DOM elements that accept a value attribute should populate correctly.

None of the above answers worked for me. I have been 2 days working out the way to migrate a Vagrant + VirtualBox Machine from a computer to another... It's possible!

First, you need to understand that the virtual machine is separated from your sync / shared folder. So when you pack your machine you're packing it without your files, but with the databases.

What you need to do:

1- Open the CMD of your computer 1 host machine (Command line. Open it as Adminitrator with the right button -> "Run as administrator") and go to your vagrant installed files. On my case: C:/VVV You will see your Vagrantfile an also these folders:

/config/
/database/
/log/
/provision/
/www/
Vagrantfile
...

The /www/ folder is where I have my Sync Folder with my development domains. You may have your sync folder in other place, just be sure to understand what you are doing. Also /config and /database are sync folders.

2- run this command: vagrant package --vagrantfile Vagrantfile

(This command does a package of your virtual machine using you Vagrantfile configuration.)

Here's what you can read on the Vagrant documentation about the command:

A common misconception is that the --vagrantfile option will package a Vagrantfile that is used when vagrant init is used with this box. This is not the case. Instead, a Vagrantfile is loaded and read as part of the Vagrant load process when the box is used. For more information, read about the Vagrantfile load order.

https://www.vagrantup.com/docs/cli/package.html

When finnished, you will have a package.box file.

3- Copy all these files (/config, /database, Vagrantfile, package.box, etc.) and paste them on your Computer 2 just where you want to install your virtual machine (on my case D:/VVV).

Now you have a copy of everything you need on your computer 2 host.

4- run this: vagrant box add package.box --name VVV

(The --name is used to name your virtual machine. On my case it's named VVV) (You can use --force if you already have a virtual machine with this name and want to overwrite it. (Use carefully !))

This will unpack your new vagrant Virtual machine.

5- When finnished, run: vagrant up

The machine will install and you should see it on the "Oracle virtual machine box manager". If you cannot see the virtual machine, try running the Oracle VM box as administrator (right click -> Run as administrator)

You now may have everything ok but remember to see if your hosts are as you expected:

c:/windows/system32/hosts

6- Maybe it's a good idea to copy your host file from your Computer 1 to your Computer 2. Or copy the lines you need. In my case these are the hosts I need:

192.168.50.4 test.dev
192.168.50.4 vvv.dev
...

Where the 192.168.50.4 is the IP of my Virtual machine and test.dev and vvv.dev are developing hosts.

I hope this can help you :) I'll be happy if you feedback your go.

Some particularities of my case that you may find:

When I ran vagrant up, there was a problem with mysql, it wasn't working. I had to run on the Virtual server (right click on the oracle virtual machine -> Show console): apt-get install mysql-server

After this, I ran again vagrant up and everything was working but without data on the databases. So I did a mysqldump all-tables from the Computer 1 and upload them to Computer 2.

OTHER NOTES: My virtual machine is not exactly on Computer 1 and Computer 2. For example, I made some time ago internal configuration to use NFS (to speed up the server sync folders) and I needed to run again this command on the Computer 2 host: vagrant plugin install vagrant-winnfsd

Another pure css based solution that is based on two clipped rounded elements that i rotate to get to the right angle:

http://jsfiddle.net/maayan/byT76/

That's the basic css that enables it:

.clip1 {
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
}
.slice1 {
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,100px,200px,0px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

.clip2 
{
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0,100px,200px,0px);
}

.slice2
{
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

and the js rotates it as required.

quite easy to understand..

Hope it helps, Maayan

Add some css either in the head or in a external document. asp:TextBox are rendered as input :

input {
     width:100%;
}

Your html should look like : http://jsfiddle.net/c5WXA/

Note this will affect all your textbox : if you don't want this, give the containing div a class and specify the css.

.divClass input {
     width:100%;
}

For CentOS 6.x and 7.x (including Amazon Linux) use:

sudo httpd -V

This will show you which of the MPMs are configured. Either prefork, worker, or event. Prefork is the earlier, threadsafe model. Worker is multi-threaded, and event supports php-mpm which is supposed to be a better system for handling threads and requests.

However, your results may vary, based on configuration. I've seen a lot of instability in php-mpm and not any speed improvements. An aggressive spider can exhaust the maximum child processes in php-mpm quite easily.

The setting for prefork, worker, or event is set in sudo nano /etc/httpd/conf.modules.d/00-mpm.conf (for CentOS 6.x/7.x/Apache 2.4).

# Select the MPM module which should be used by uncommenting exactly
# one of the following LoadModule lines:

# prefork MPM: Implements a non-threaded, pre-forking web server
# See: http://httpd.apache.org/docs/2.4/mod/prefork.html
#LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

# worker MPM: Multi-Processing Module implementing a hybrid
# multi-threaded multi-process web server
# See: http://httpd.apache.org/docs/2.4/mod/worker.html
#LoadModule mpm_worker_module modules/mod_mpm_worker.so

# event MPM: A variant of the worker MPM with the goal of consuming
# threads only for connections with active processing
# See: http://httpd.apache.org/docs/2.4/mod/event.html
#LoadModule mpm_event_module modules/mod_mpm_event.so

Simply do (mouseenter) attribute in Angular2+...

In your HTML do:

<div (mouseenter)="mouseHover($event)">Hover!</div> 

and in your component do:

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'component',
  templateUrl: './component.html',
  styleUrls: ['./component.scss']
})

export class MyComponent implements OnInit {

  mouseHover(e) {
    console.log('hovered', e);
  }
} 

To apply it everywhere, you could do something like

$('body').on('click', function() {
   if($('.children').is(':visible')) {
      $('ul.children').slideUp('slow');
   }
});

UPDATE:

onActivityCreated() is deprecated from API Level 28.

onCreate():

The onCreate() method in a Fragment is called after the Activity's onAttachFragment() but before that Fragment's onCreateView().
In this method, you can assign variables, get Intent extras, and anything else that doesn't involve the View hierarchy (i.e. non-graphical initialisations). This is because this method can be called when the Activity's onCreate() is not finished, and so trying to access the View hierarchy here may result in a crash.

onCreateView():

After the onCreate() is called (in the Fragment), the Fragment's onCreateView() is called. You can assign your View variables and do any graphical initialisations. You are expected to return a View from this method, and this is the main UI view, but if your Fragment does not use any layouts or graphics, you can return null (happens by default if you don't override).

onActivityCreated():

As the name states, this is called after the Activity's onCreate() has completed. It is called after onCreateView(), and is mainly used for final initialisations (for example, modifying UI elements). This is deprecated from API level 28.

To sum up...
... they are all called in the Fragment but are called at different times.
The onCreate() is called first, for doing any non-graphical initialisations. Next, you can assign and declare any View variables you want to use in onCreateView(). Afterwards, use onActivityCreated() to do any final initialisations you want to do once everything has completed.

If you want to view the official Android documentation, it can be found here:

• onCreate()
• onCreateView()
• onActivityCreated()_

There are also some slightly different, but less developed questions/answers here on Stack Overflow:

• onCreate() vs onCreateView()
• onCreateView() vs onActivityCreated()

This error can be triggered by your own computer too, and not just an unhandled exception. If your server/computer has its clock time off by too many minutes, many .NET web services will reject your request with an unhandled error. It's handled from their point of view, but unhandled from your point. Check to make sure your receiving server's clock time is correct. If it needs to be fixed, you'll have to reset your service or reboot before the channel reopens.

I experienced this issue on a server where the firewall blocked the Internet time update, and the server got off time for some reason. All the 3rd party .NET web services went into fault because they rejected any web service request. Digging into the Event Viewer helped identify the problem, but adjusting the clock solved it. The error was on our end even though we received the Faulted State error message for future web service calls.

I have written an add-in for SSMS and this problem is fixed there. You can use one of 2 ways:

you can use "Copy current cell 1:1" to copy original cell data to clipboard:

http://www.ssmsboost.com/Features/ssms-add-in-copy-results-grid-cell-contents-line-with-breaks

Or, alternatively, you can open cell contents in external text editor (notepad++ or notepad) using "Cell visualizers" feature: http://www.ssmsboost.com/Features/ssms-add-in-results-grid-visualizers

(feature allows to open contents of field in any external application, so if you know that it is text - you use text editor to open it. If contents is binary data with picture - you select view as picture. Sample below shows opening a picture):

I wanted to edit several events in descendant chonologic order, and I just made a :

and it works for me. But surely not adapted for every case... Just hope it'll help someone !

When dialing a number within the country you are in, you still need to dial the national trunk number before the rest of the number. For example, in Australia one would dial:

   0 - trunk prefix
   2 - Area code for New South Wales
6555 - STD code for a specific telephone exchange
1234 - Telephone Exchange specific extension.

For a mobile phone this becomes

   0 -      trunk prefix
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

Now, when I want to dial via the international trunk, you need to drop the trunk prefix and replace it with the international dialing prefix

   + -      Short hand for the country trunk number
  61 -      Country code for Australia
   4 -      Area code for a mobile telephone
1234 5678 - Mobile telephone number

This is why you often find that the first digit of a telephone number is dropped when dialling internationally, even when using international prefixing to dial within the same country.

So as per the trunk prefix for Germany drop the 0 and add the +49 for Germany's international calling code (for example) giving:

<a href="tel:+496170961709" class="Blondie">_x000D_
    Call me, call me any, anytime_x000D_
      <b>Call me (call me) I'll arrive</b>_x000D_
        When you're ready we can share the wine!_x000D_
</a>

I also faced problem in .Net Remoting Service in C#.

I got it solved in 3 steps:

1. Change Port of Protocol in all the files whereever it is being used.
2. Run your Host Server Program and make it active.
3. Now run your client program.

For those of you (like me) that wasted too much time from this error:

I had received the same error: "Could not find implementation of query Pattern for source type 'DbSet'" but the solution for me was fixing a mistake at the DbContext level.

When I created my context I had this:

public class ContactContext : DbContext
    {
        public ContactContext() : base() { }

        public DbSet Contacts { get; set; }
    }

And my Repository (I was following a Repository pattern in ASP.NET guide) looked like this:

public Contact FindById(int id)
    {       
        var contact = from c in _db.Contacts where c.Id == id select c;
        return contact;
    }

My issue came from the initial setup of my DbContext, when I used DbSet as a generic instead of the type.

I changed public DbSet Contacts { get; set; } to public DbSet<Contact> Contacts { get; set; } and suddenly the query was recognized.

This is probably what k.m says in his answer, but since he mentioned IEnumerable<t> and not DbSet<<YourDomainObject>> I had to dig around in the code for a couple hours to find the line that caused this headache.

.scroll {
   width: 200px; height: 400px;
   overflow: auto;
}

Use the sleep command.

Example:

sleep .5 # Waits 0.5 second.
sleep 5  # Waits 5 seconds.
sleep 5s # Waits 5 seconds.
sleep 5m # Waits 5 minutes.
sleep 5h # Waits 5 hours.
sleep 5d # Waits 5 days.

One can also employ decimals when specifying a time unit; e.g. sleep 1.5s

To summarize or simplify,

2xx: Optional data: Well formed URI: Criteria is not part of URI: If the criteria is optional that can be specified in @RequestBody and @RequestParam should lead to 2xx. Example: filter by name / status

4xx: Expected data : Not well formed URI : Criteria is part of URI : If the criteria is mandatory that can only be specified in @PathVariable then it should lead to 4xx. Example: lookup by unique id.

Thus for the asked situation: "users/9" would be 4xx (possibly 404) But for "users?name=superman" should be 2xx (possibly 204)

string StringFold(string input, Func<char, string> proc)
{
  return string.Concat(input.Select(proc).ToArray());
}

string FoldProc(char input)
{
  if (input >= 128)
  {
    return string.Format(@"\u{0:x4}", (int)input);
  }
  return input.ToString();
}

string EscapeToAscii(string input)
{
  return StringFold(input, FoldProc);
}

For mac it's simple:

brew install libtool

declare @t  tinyint
set @t =3
select right(replicate('0', 2) + cast(@t as varchar),2)

Ditto: on the cripping effect for numbers > 99

If you want to cater for 1-255 then you could use

select right(replicate('0', 2) + cast(@t as varchar),3)

But this would give you 001, 010, 100 etc

This is how I was able to configure yaml files to refer to variable.

I have values.yaml where we have root level fields which are used as template variables inside values.yaml

values.yaml

.....  
databaseUserPropName: spring.datasource.username  
databaseUserName: sa  
.....  
secrets:
    type: Opaque  
    name: dbservice-secrets  
    data:  
      - name: "{{ .Values.databaseUserPropName }}"  
        value: "{{ .Values.databaseUserName }}"  
.....

When referencing these values in secret.yaml, we would use tpl function using syntax {{ tpl TEMPLATE_STRING VALUES }}

secret.yaml

when using inside range i:e iteration

  {{ range .Values.deployments.secrets.data }}
    {{ tpl .name $ }}: "{{ tpl .value $ }}"
  {{ end }}

when directly referring as variable

  {{ tpl .Values.deployments.secrets.data.name . }}
  {{ tpl .Values.deployments.secrets.data.value . }}

$ - this is global variable and will always point to the root context . - this variable will point to the root context based on where it used.

In Java, you cannot set a value in ArrayList by assigning to it, there's a set() method to call:

String a = words.get(0);
words.set(0, words.get(words.size() - 1));
words.set(words.size() - 1, a)

As of Go1.1 release, there is a bufio.Scanner API that can easily read lines from a file. Consider the following example from above, rewritten with Scanner:

package main

import (
    "bufio"
    "fmt"
    "log"
    "os"
)

// readLines reads a whole file into memory
// and returns a slice of its lines.
func readLines(path string) ([]string, error) {
    file, err := os.Open(path)
    if err != nil {
        return nil, err
    }
    defer file.Close()

    var lines []string
    scanner := bufio.NewScanner(file)
    for scanner.Scan() {
        lines = append(lines, scanner.Text())
    }
    return lines, scanner.Err()
}

// writeLines writes the lines to the given file.
func writeLines(lines []string, path string) error {
    file, err := os.Create(path)
    if err != nil {
        return err
    }
    defer file.Close()

    w := bufio.NewWriter(file)
    for _, line := range lines {
        fmt.Fprintln(w, line)
    }
    return w.Flush()
}

func main() {
    lines, err := readLines("foo.in.txt")
    if err != nil {
        log.Fatalf("readLines: %s", err)
    }
    for i, line := range lines {
        fmt.Println(i, line)
    }

    if err := writeLines(lines, "foo.out.txt"); err != nil {
        log.Fatalf("writeLines: %s", err)
    }
}

In Rails 3.2.18, :decimal turns into :integer when using SQLServer, but it works fine in SQLite. Switching to :float solved this issue for us.

The lesson learned is "always use homogeneous development and deployment databases!"

Each database's implementation but you can probably guess that they all solve common problems in more or less the same way. If you are using MSSQL have a look at the execution plan that is generated. You can do this by turning on the profiler and executions plans. This will give you a text version when you run the command.

I am not sure what version of MSSQL you are using but you can get a graphical one in SQL Server 2000 in the query analyzer. I am sure that this functionality is lurking some where in SQL Server Studio Manager in later versions.

Have a look at the exeuction plan. As far as possible avoid table scans unless of course your table is small in which case a table scan is faster than using an index. Read up on the different join operations that each different scenario produces.

Somebody asked me to post a link to the framework! that I presented at Open World 2012. This is the full blog post that demonstrates how to architect a solution with external tables.

I resolved this of following way:

• I've assigned a name to window this name is the same of connection resource.
• plus 1 to rid stored in cookie for attach connection.
• I've created a function to capture all xmloutput response and assign sid and rid to cookie in json format. I do this for each window.name.

here the code:

var deferred = $q.defer(),
        self = this,
        onConnect = function(status){
          if (status === Strophe.Status.CONNECTING) {
            deferred.notify({status: 'connecting'});
          } else if (status === Strophe.Status.CONNFAIL) {
            self.connected = false;
            deferred.notify({status: 'fail'});
          } else if (status === Strophe.Status.DISCONNECTING) {
            deferred.notify({status: 'disconnecting'});
          } else if (status === Strophe.Status.DISCONNECTED) {
            self.connected = false;
            deferred.notify({status: 'disconnected'});
          } else if (status === Strophe.Status.CONNECTED) {
            self.connection.send($pres().tree());
            self.connected = true;
            deferred.resolve({status: 'connected'});
          } else if (status === Strophe.Status.ATTACHED) {
            deferred.resolve({status: 'attached'});
            self.connected = true;
          }
        },
        output = function(data){
          if (self.connected){
            var rid = $(data).attr('rid'),
                sid = $(data).attr('sid'),
                storage = {};

            if (localStorageService.cookie.get('day_bind')){
              storage = localStorageService.cookie.get('day_bind');
            }else{
              storage = {};
            }
            storage[$window.name] = sid + '-' + rid;
            localStorageService.cookie.set('day_bind', angular.toJson(storage));
          }
        };
    if ($window.name){
      var storage = localStorageService.cookie.get('day_bind'),
          value = storage[$window.name].split('-')
          sid = value[0],
          rid = value[1];
      self.connection = new Strophe.Connection(BoshService);
      self.connection.xmlOutput = output;
      self.connection.attach('bosh@' + BoshDomain + '/' + $window.name, sid, parseInt(rid, 10) + 1, onConnect);
    }else{
      $window.name = 'web_' + (new Date()).getTime();
      self.connection = new Strophe.Connection(BoshService);
      self.connection.xmlOutput = output;
      self.connection.connect('bosh@' + BoshDomain + '/' + $window.name, '123456', onConnect);
    }

I hope help you

if you are interested in a ready solution then you may look at HumanizerCpp library (https://github.com/trodevel/HumanizerCpp) - it is a port of C# Humanizer library and it does exactly what you want.

It can even convert to ordinals and currently supports 3 languages: English, German and Russian.

Example:

const INumberToWordsConverter * e = Configurator::GetNumberToWordsConverter( "en" );

std::cout << e->Convert( 123 ) << std::endl;
std::cout << e->Convert( 1234 ) << std::endl;
std::cout << e->Convert( 12345 ) << std::endl;
std::cout << e->Convert( 123456 ) << std::endl;

std::cout << std::endl;
std::cout << e->ConvertToOrdinal( 1001 ) << std::endl;
std::cout << e->ConvertToOrdinal( 1021 ) << std::endl;


const INumberToWordsConverter * g = Configurator::GetNumberToWordsConverter( "de" );

std::cout << std::endl;
std::cout << g->Convert( 123456 ) << std::endl;

const INumberToWordsConverter * r = Configurator::GetNumberToWordsConverter( "ru" );

std::cout << r->ConvertToOrdinal( 1112 ) << std::endl;

Output:

one hundred and twenty-three
one thousand two hundred and thirty-four
twelve thousand three hundred and forty-five
one hundred and twenty-three thousand four hundred and fifty-six

thousand and first
thousand and twenty-first

einhundertdreiundzwanzigtausendvierhundertsechsundfünfzig

In any case you may take a look at the source code and reuse in your project or try to understand the logic. It is written in pure C++ without external libraries.

As an addon to Dima V's answer this is what I did to make this work for me.

// First declare the window global outside the class

declare let window: any;

// Inside the required class method

let globVarName = window.globVarName;

IF is used to select the field, then the LIKE clause is placed after it:

SELECT  `id` ,  `naam` 
FROM  `klanten` 
WHERE IF(`email` != '', `email`, `email2`) LIKE  '%@domain.nl%'

I encountered the same problem , my resolution was to rename the the folder name under the workspace folder. i.e. com.ibm.collaboration.realtime.alertmanager.embedded was renamed to com.ibm.collaboration.realtime.alertmanager.2embeddedxx and rebuilt my project.

You can use /* tslint:disable-next-line */ to locally disable tslint. However, as this is a compiler error disabling tslint might not help.

You can always temporarily cast $ to any:

delete ($ as any).summernote.options.keyMap.pc.TAB

which will allow you to access whatever properties you want.

Edit: As of Typescript 2.6, you can now bypass a compiler error/warning for a specific line:

if (false) {
    // @ts-ignore: Unreachable code error
    console.log("hello");
}

Note that the official docs "recommend you use [this] very sparingly". It is almost always preferable to cast to any instead as that better expresses intent.

I successfully used "soap" package (https://www.npmjs.com/package/soap) on more than 10 tracking WebApis (Tradetracker, Bbelboon, Affilinet, Webgains, ...).

Problems usually come from the fact that programmers does not investigate to much about what remote API needs in order to connect or authenticate.

For instance PHP resends cookies from HTTP headers automatically, but when using 'node' package, it have to be explicitly set (for instance by 'soap-cookie' package)...

I recommend using the os module to avoid trouble in cross-platform. (windows,linux,mac)

Cause if the directory doesn't exists, it will return an exception.

import os

filepath = os.path.join('c:/your/full/path', 'filename')
if not os.path.exists('c:/your/full/path'):
    os.makedirs('c:/your/full/path')
f = open(filepath, "a")

If this will be a function for a system or something, you can improve it by adding try/except for error control.

You can also change the index name in column definitions within a create_table block (such as you get from the migration generator).

create_table :studies do |t|
  t.references :user, index: {:name => "index_my_shorter_name"}
end

copy this line and replace in your project

var myNewString = myOldString.replace ("username", visitorName);

there is a simple problem with coma (,)

If you'd like to iterate over all elements concurrently:

async function asyncForEach(arr, fn) {
  await Promise.all(arr.map(fn));
}

If you'd like to iterate over all elements non-concurrently (e.g. when your mapping function has side effects or running mapper over all array elements at once would be too resource costly):

Option A: Promises

function asyncForEachStrict(arr, fn) {
  return new Promise((resolve) => {
    arr.reduce(
      (promise, cur, idx) => promise
        .then(() => fn(cur, idx, arr)),
      Promise.resolve(),
    ).then(() => resolve());
  });
}

Option B: async/await

async function asyncForEachStrict(arr, fn) {
  for (let idx = 0; idx < arr.length; idx += 1) {
    const cur = arr[idx];

    await fn(cur, idx, arr);
  }
}

Found what was wrong. I don't understand how, but .git directory path somehow was changed to other path than I was working in. So then anything I changed was not checked, because git was checking in other place. I noticed it, when I reinitialized it and it showed that it reinitialized entirely different directory. When I cd .. from my current directory and cd to it back again and then reinitialized yet again, then it switched back to correct .git directory and started seeing my changes.

Arrays innately manage their lengths. As they are traversed, their indexes can be held in memory and referenced at that point. If a random index needs to be known, the indexOf method can be used.

This said, for your needs you may just want to declare an array of a certain size:

var foo = new Array(N);   // where N is a positive integer

/* this will create an array of size, N, primarily for memory allocation, 
   but does not create any defined values

   foo.length                                // size of Array
   foo[ Math.floor(foo.length/2) ] = 'value' // places value in the middle of the array
*/

ES6

Spread

Making use of the spread operator (...) and keys method, enables you to create a temporary array of size N to produce the indexes, and then a new array that can be assigned to your variable:

var foo = [ ...Array(N).keys() ];

Fill/Map

You can first create the size of the array you need, fill it with undefined and then create a new array using map, which sets each element to the index.

var foo = Array(N).fill().map((v,i)=>i);

Array.from

This should be initializing to length of size N and populating the array in one pass.

Array.from({ length: N }, (v, i) => i)

In lieu of the comments and confusion, if you really wanted to capture the values from 1..N in the above examples, there are a couple options:

1. if the index is available, you can simply increment it by one (e.g., ++i).

2. in cases where index is not used -- and possibly a more efficient way -- is to create your array but make N represent N+1, then shift off the front.

   So if you desire 100 numbers:

   let arr; (arr=[ ...Array(101).keys() ]).shift()

Just clear the scope model value on click event and it should do the trick for you.

<input type="text" ng-model="searchAll" />
<a class="clear" ng-click="searchAll = null">

</a>

Or if you keep your controller's $scope function and clear it from there. Make sure you've set your controller correctly.

$scope.clearSearch = function() {
    $scope.searchAll = null;
}

If you need a floating random number between 13 and 20

(20-13).*rand(1) + 13

If you need an integer random number between 13 and 20

floor((21-13).*rand(1) + 13)

Note: Fix problem mentioned in comment "This excludes 20" by replacing 20 with 21

How to start service on device boot(autorun app, etc.)

For first: since version Android 3.1+ you don't receive BOOT_COMPLETE if user never started your app at least once or user "force closed" application. This was done to prevent malware automatically register service. This security hole was closed in newer versions of Android.

Solution:

Create app with activity. When user run it once app can receive BOOT_COMPLETE broadcast message.

For second: BOOT_COMPLETE is sent before external storage is mounted. If app is installed to external storage it won't receive BOOT_COMPLETE broadcast message.

In this case there is two solution:

1. Install your app to internal storage
2. Install another small app in internal storage. This app receives BOOT_COMPLETE and run second app on external storage.

If your app already installed in internal storage then code below can help you understand how to start service on device boot.

In Manifest.xml

Permission:

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

Register your BOOT_COMPLETED receiver:

<receiver android:name="org.yourapp.OnBoot">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver>

Register your service:

<service android:name="org.yourapp.YourCoolService" />

In receiver OnBoot.java:

public class OnBoot extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        // Create Intent
        Intent serviceIntent = new Intent(context, YourCoolService.class);
        // Start service
        context.startService(serviceIntent);

    }

 }

For HTC you maybe need also add in Manifest this code if device don't catch RECEIVE_BOOT_COMPLETED:

<action android:name="android.intent.action.QUICKBOOT_POWERON" />

Receiver now look like this:

<receiver android:name="org.yourapp.OnBoot">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
    </intent-filter>
</receiver>

How to test BOOT_COMPLETED without restart emulator or real device? It's easy. Try this:

adb -s device-or-emulator-id shell am broadcast -a android.intent.action.BOOT_COMPLETED

How to get device id? Get list of connected devices with id's:

adb devices

adb in ADT by default you can find in:

adt-installation-dir/sdk/platform-tools

Well try my code, atleast it gives you a string as overlay, you can very well replace it with a button or an image. You wont believe this is my first ever android app LOL. Anyways if you are more experienced with android apps than me, please try

• changing parameters 2 and 3 in "new WindowManager.LayoutParams"
• try some different event approach

Define myurl command:

\def\myurl{\hfil\penalty 100 \hfilneg \hbox}

I don't want to cause line overflows, 
I'd just rather LaTeX insert linebreaks before 
\myurl{\tt http://stackoverflow.com/questions/1012799/} 
regions rather than inside them.

TextView does not support setMargins. Android docs say:

Even though a view can define a padding, it does not provide any support for margins. However, view groups provide such a support. Refer to ViewGroup and ViewGroup.MarginLayoutParams for further information.

Actually you should define your styles in res/values/styles.xml. I guess now you've got the following configuration:

<style name="AppBaseTheme" parent="android:Theme.Holo.Light"/>
<style name="AppTheme" parent="AppBaseTheme"/>

so if you want to use Theme.Black then change AppBaseTheme parent to android:Theme.Black or you could change app style directly in manifest file like this - android:theme="@android:style/Theme.Black". You must be lacking android namespace before style tag.

You can read more about styles and themes here.

You could do something along these lines (which worked in both Python v2.7.17 and v3.8.1 when I tested it/them):

def hi():
    # other code...
    hi.bye = 42  # Create function attribute.
    sigh = 10

hi()
print(hi.bye)  # -> 42

Functions are objects in Python and can have arbitrary attributes assigned to them.

If you're going to be doing this kind of thing often, you could implement something more generic by creating a function decorator that adds a this argument to each call to the decorated function.

This additional argument will give functions a way to reference themselves without needing to explicitly embed (hardcode) their name into the rest of the definition and is similar to the instance argument that class methods automatically receive as their first argument which is usually named self — I picked something different to avoid confusion, but like the self argument, it can be named whatever you wish.

Here's an example of that approach:

def add_this_arg(func):
    def wrapped(*args, **kwargs):
        return func(wrapped, *args, **kwargs)
    return wrapped

@add_this_arg
def hi(this, that):
    # other code...
    this.bye = 2 * that  # Create function attribute.
    sigh = 10

hi(21)
print(hi.bye)  # -> 42

Note

This doesn't work for class methods. Just use the self argument already passed being passed to instead of the method name. You can reference class-level attributes through type(self). See Function's attributes when in a class.

This is @Jason's answer but with simplified output

SELECT name, CASE WHEN value = 1 THEN 'YES' ELSE 'NO' END AS 'Enabled'
FROM sys.configurations WHERE name = 'clr enabled'

The above returns the following:

| name        | Enabled |
-------------------------
| clr enabled | YES     |

Tested on SQL Server 2017

I was debugging an issue with git and needed some very verbose output to figure out what was going wrong. I ended up setting the GIT_TRACE environment variable:

export GIT_TRACE=1
git add *.txt

You can also use these on the same line:

GIT_TRACE=1 git add *.txt

Output:

14:06:05.508517 git.c:415               trace: built-in: git add test.txt test2.txt
14:06:05.544890 git.c:415               trace: built-in: git config --get oh-my-zsh.hide-dirty

There's a short overview at MinGW-w64 Wiki:

Why doesn't mingw-w64 gcc support Dwarf-2 Exception Handling?

The Dwarf-2 EH implementation for Windows is not designed at all to work under 64-bit Windows applications. In win32 mode, the exception unwind handler cannot propagate through non-dw2 aware code, this means that any exception going through any non-dw2 aware "foreign frames" code will fail, including Windows system DLLs and DLLs built with Visual Studio. Dwarf-2 unwinding code in gcc inspects the x86 unwinding assembly and is unable to proceed without other dwarf-2 unwind information.

The SetJump LongJump method of exception handling works for most cases on both win32 and win64, except for general protection faults. Structured exception handling support in gcc is being developed to overcome the weaknesses of dw2 and sjlj. On win64, the unwind-information are placed in xdata-section and there is the .pdata (function descriptor table) instead of the stack. For win32, the chain of handlers are on stack and need to be saved/restored by real executed code.

GCC GNU about Exception Handling:

GCC supports two methods for exception handling (EH):

• DWARF-2 (DW2) EH, which requires the use of DWARF-2 (or DWARF-3) debugging information. DW-2 EH can cause executables to be slightly bloated because large call stack unwinding tables have to be included in th executables.
• A method based on setjmp/longjmp (SJLJ). SJLJ-based EH is much slower than DW2 EH (penalising even normal execution when no exceptions are thrown), but can work across code that has not been compiled with GCC or that does not have call-stack unwinding information.

[...]

Structured Exception Handling (SEH)

Windows uses its own exception handling mechanism known as Structured Exception Handling (SEH). [...] Unfortunately, GCC does not support SEH yet. [...]

I always use store.proxy.reader.jsonData or store.proxy.reader.rawData

For example - this return the items nested into a root node called 'data':

var some_store = Ext.data.StoreManager.lookup('some_store_id');
Ext.each(some_store.proxy.reader.rawData.data, function(obj, i){
   console.info(obj);
});

This only works immediately after a store read-operation (while not been manipulated yet).

IISReset restarts the entire webserver (including all associated sites). If you're just looking to reset a single ASP.NET website, you should just recycle that Application Domain.

What about:

int a_as_int = (int)'a';

SQL Server allows you to join tables from different databases as long as those databases are on the same server. The join syntax is the same; the only difference is that you must fully specify table names.

Let's suppose you have two databases on the same server - Db1 and Db2. Db1 has a table called Clients with a column ClientId and Db2 has a table called Messages with a column ClientId (let's leave asside why those tables are in different databases).

Now, to perform a join on the above-mentioned tables you will be using this query:

select *
from Db1.dbo.Clients c
join Db2.dbo.Messages m on c.ClientId = m.ClientId

I am currently developing an web application with EF Core and here is the pattern I use:

All my classes (tables) have an int PK and FK. I then have an additional column of type Guid (generated by the C# constructor) with a non clustered index on it.

All the joins of tables within EF are managed through the int keys while all the access from outside (controllers) are done with the Guids.

This solution allows to not show the int keys on URLs but keep the model tidy and fast.

If you want the results to be case insensitive, the following will work:

List<string> list1 = new List<string> { "a.dll", "b1.dll" };
List<string> list2 = new List<string> { "A.dll", "b2.dll" };

var firstNotSecond = list1.Except(list2, StringComparer.OrdinalIgnoreCase).ToList();
var secondNotFirst = list2.Except(list1, StringComparer.OrdinalIgnoreCase).ToList();

firstNotSecond would contain b1.dll

secondNotFirst would contain b2.dll

The referenced field must be a "Key" in the referenced table, not necessarily a primary key. So the "car_id" should either be a primary key or be defined with NOT NULL and UNIQUE constraints in the "Cars" table.

And moreover, both fields must be of the same type and collation.

I say const your value parameters.

Consider this buggy function:

bool isZero(int number)
{
  if (number = 0)  // whoops, should be number == 0
    return true;
  else
    return false;
}

If the number parameter was const, the compiler would stop and warn us of the bug.

I'm not sure, but I think the second parameter is a red herring.

Both .Rows and .Columns take two optional parameters: RowIndex and ColumnIndex. Try to use ColumnIndex, e.g. Rows(ColumnIndex:=2), generates an error for both .Rows and .Columns.

My feeling it's inherited in some sense from the Cells(RowIndex,ColumnIndex) Property but only the first parameter is appropriate.

Like @Shoaib answered, you dont need any jQuery or Javascript. You can to this simply with pure html!

<form method="POST" action="index.php?action=contact_agent">
  <select name="agent_id" required>
    <option value="1">Agent Homer</option>
    <option value="2">Agent Lenny</option>
    <option value="3">Agent Carl</option>
  </select>
  <input type="submit" value="Submit">
</form>

1. Remove &agent_id= from form action since you don't need it there.
2. Add name="agent_id" to the select
3. Optionally add word required do indicate that this selection is required.

Since you are using PHP, then by posting the form to index.php you can catch agent_id with $_POST

/** Since you reference action on `form action` then value of $_GET['action'] will be contact_agent */
$action = $_GET['action'];

/** Value of $_POST['agent_id'] will be selected option value */
$agent_id = $_POST['agent_id']; 

As conclusion for such a simple task you should not use any javascript or jQuery. To @FelipeAlvarez that answers your comment

With Java 8 or newer, you can use String.join, which provides the same functionality:

Returns a new String composed of copies of the CharSequence elements joined together with a copy of the specified delimiter

String[] array = new String[] { "a", "n", "d", "r", "o", "i", "d" };
String joined = String.join("", array); //returns "android"

With an array of a different type, one should convert it to a String array or to a char sequence Iterable:

int[] numbers = { 1, 2, 3, 4, 5, 6, 7 };

//both of the following return "1234567"
String joinedNumbers = String.join("",
        Arrays.stream(numbers).mapToObj(String::valueOf).toArray(n -> new String[n]));
String joinedNumbers2 = String.join("",
        Arrays.stream(numbers).mapToObj(String::valueOf).collect(Collectors.toList()));

The first argument to String.join is the delimiter, and can be changed accordingly.

The best way is to prevent the default action. In the case of anchor tag, the default behavior is redirecting to href specified address.

So following javascript works best in the situation:

$('#ThisLink').click(function(e)
{
    e.preventDefault();
});

Try moving ValueDate:

select sum(CASE  
             WHEN ValueDate > @startMonthDate THEN cash 
              ELSE 0 
           END) 
 from Table a
where a.branch = p.branch 
  and a.transID = p.transID

(reformatted for clarity)

You might also consider using '0' instead of NULL, as you are doing a sum. It works correctly both ways, but is maybe more indicitive of what your intentions are.

In order to make

     http://localhost:8080

work, tomcat has to be started first. You can check server.xml file in conf folder for the port information. You can search if tomcat is installed on your machine. Just go to start and then type tomcat. If it is installed it will give you the directory where it is installed. Then you can select that path and run it from command prompt. Example if tomcat is installed in C:\Programfile\tomcat. You need to set this path in command prompt,go to bin folder and startup. Example: C:\Programfile\tomcat\bin\startup. Else you can also run it by directly going to the path and run startup batch file.

Let me give some examples.

Consider this data.

CREATE TABLE DATASET ( VAL1 CHAR ( 1 CHAR ),
                   VAL2 VARCHAR2 ( 10 CHAR ),
                   VAL3 NUMBER );

INSERT INTO
      DATASET ( VAL1, VAL2, VAL3 )
VALUES
      ( 'b', 'b-details', 2 );

INSERT INTO
      DATASET ( VAL1, VAL2, VAL3 )
VALUES
      ( 'a', 'a-details', 1 );

INSERT INTO
      DATASET ( VAL1, VAL2, VAL3 )
VALUES
      ( 'c', 'c-details', 3 );

INSERT INTO
      DATASET ( VAL1, VAL2, VAL3 )
VALUES
      ( 'a', 'dup', 4 );

INSERT INTO
      DATASET ( VAL1, VAL2, VAL3 )
VALUES
      ( 'c', 'c-details', 5 );

COMMIT;

Whats there in table now

SELECT * FROM DATASET;

You have N columns in select (excluding aggregations), then you should have N or N+x columns

You can use the Logical NOT ! operator:

if (!$(this).parent().next().is('ul')){

Or equivalently (see comments below):

if (! ($(this).parent().next().is('ul'))){

For more information, see the Logical Operators section of the MDN docs.

The concatenation operator + is a binary infix operator which, when applied to lists, returns a new list containing all the elements of each of its two operands. The list.append() method is a mutator on list which appends its single object argument (in your specific example the list c) to the subject list. In your example this results in c appending a reference to itself (hence the infinite recursion).

An alternative to '+' concatenation

The list.extend() method is also a mutator method which concatenates its sequence argument with the subject list. Specifically, it appends each of the elements of sequence in iteration order.

An aside

Being an operator, + returns the result of the expression as a new value. Being a non-chaining mutator method, list.extend() modifies the subject list in-place and returns nothing.

Arrays

I've added this due to the potential confusion which the Abel's answer above may cause by mixing the discussion of lists, sequences and arrays. Arrays were added to Python after sequences and lists, as a more efficient way of storing arrays of integral data types. Do not confuse arrays with lists. They are not the same.

From the array docs:

Arrays are sequence types and behave very much like lists, except that the type of objects stored in them is constrained. The type is specified at object creation time by using a type code, which is a single character.

I know this is an old question.

Here's another option - attending to different platform requirements - Source

<link rel='shortcut icon' type='image/vnd.microsoft.icon' href='/favicon.ico'> <!-- IE -->
<link rel='apple-touch-icon' type='image/png' href='/icon.57.png'> <!-- iPhone -->
<link rel='apple-touch-icon' type='image/png' sizes='72x72' href='/icon.72.png'> <!-- iPad -->
<link rel='apple-touch-icon' type='image/png' sizes='114x114' href='/icon.114.png'> <!-- iPhone4 -->
<link rel='icon' type='image/png' href='/icon.114.png'> <!-- Opera Speed Dial, at least 144×114 px -->

This is the broadest approach I have found so far.

Ultimately the decision depends on your own needs. Ask yourself, who is your target audience?

UPDATE May 27, 2018: As expected, time goes by and things change. But there's good news too. I found a tool called Real Favicon Generator that generates all the required lines for the icon to work on all modern browsers and platforms. It doesn't handle backwards compatibility though.

sudo sh -c "echo 127.0.0.1 localhost >> /etc/hosts"

Quick update to mid 2015:

You can use the Postgres Foreign Data interface, to store the files in more suitable database. For example put the files in a GridFS which is part of MongoDB. Then use https://github.com/EnterpriseDB/mongo_fdw to access it in Postgres.

That has the advantages, that you can access/read/write/backup it in Postrgres and MongoDB, depending on what gives you more flexiblity.

There are also foreign data wrappers for file systems: https://wiki.postgresql.org/wiki/Foreign_data_wrappers#File_Wrappers

As an example you can use this one: https://multicorn.readthedocs.org/en/latest/foreign-data-wrappers/fsfdw.html (see here for brief usage example)

That gives you the advantage of the consistency (all linked files are definitely there) and all the other ACIDs, while there are still on the actual file system, which means you can use any file system you want and the webserver can serve them directly (OS caching applies too).

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

Check this example:

class CartridgeShell extends React.Component {_x000D_
_x000D_
   constructor(props) {_x000D_
      super(props);_x000D_
      this.state = {value:''}_x000D_
_x000D_
      this.handleChange = this.handleChange.bind(this);_x000D_
      this.keyPress = this.keyPress.bind(this);_x000D_
   } _x000D_
 _x000D_
   handleChange(e) {_x000D_
      this.setState({ value: e.target.value });_x000D_
   }_x000D_
_x000D_
   keyPress(e){_x000D_
      if(e.keyCode == 13){_x000D_
         console.log('value', e.target.value);_x000D_
         // put the login here_x000D_
      }_x000D_
   }_x000D_
_x000D_
   render(){_x000D_
      return(_x000D_
         <input value={this.state.value} onKeyDown={this.keyPress} onChange={this.handleChange} fullWidth={true} />_x000D_
      )_x000D_
    }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<CartridgeShell/>, document.getElementById('app'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
_x000D_
_x000D_
<div id = 'app' />

Note: Replace the input element by Material-Ui TextField and define the other properties also.

 void main(){
  var x = "4";
  int number = int.parse(x);//STRING to INT

  var y = "4.6";
  double doubleNum = double.parse(y);//STRING to DOUBLE

  var z = 55;
  String myStr = z.toString();//INT to STRING
}

int.parse() and double.parse() can throw an error when it couldn't parse the String

An even more minimalistic example:

var linkedResource = new LinkedResource(@"C:\Image.jpg", MediaTypeNames.Image.Jpeg);

// My mail provider would not accept an email with only an image, adding hello so that the content looks less suspicious.
var htmlBody = $"hello<img src=\"cid:{linkedResource.ContentId}\"/>";
var alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(linkedResource);

var mailMessage = new MailMessage
{
    From = new MailAddress("[email protected]"),
    To = { "[email protected]" },
    Subject = "yourSubject",
    AlternateViews = { alternateView }
};

var smtpClient = new SmtpClient();
smtpClient.Send(mailMessage);

There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal or you can just pump up number of lines that you want to have in history in the same place.

NotFoundMVC - Provides a user-friendly 404 page whenever a controller, action or route is not found in your ASP.NET MVC3 application. A view called NotFound is rendered instead of the default ASP.NET error page.

You can add this plugin via nuget using: Install-Package NotFoundMvc

NotFoundMvc automatically installs itself during web application start-up. It handles all the different ways a 404 HttpException is usually thrown by ASP.NET MVC. This includes a missing controller, action and route.

Step by Step Installation Guide :

1 - Right click on your Project and Select Manage Nuget Packages...

2 - Search for NotFoundMvc and install it.

3 - Once the installation has be completed, two files will be added to your project. As shown in the screenshots below.

4 - Open the newly added NotFound.cshtml present at Views/Shared and modify it at your will. Now run the application and type in an incorrect url, and you will be greeted with a User friendly 404 page.

No more, will users get errors message like Server Error in '/' Application. The resource cannot be found.

Hope this helps :)

P.S : Kudos to Andrew Davey for making such an awesome plugin.

CancelAsync doesn't actually abort your thread or anything like that. It sends a message to the worker thread that work should be cancelled via BackgroundWorker.CancellationPending. Your DoWork delegate that is being run in the background must periodically check this property and handle the cancellation itself.

The tricky part is that your DoWork delegate is probably blocking, meaning that the work you do on your DataSource must complete before you can do anything else (like check for CancellationPending). You may need to move your actual work to yet another async delegate (or maybe better yet, submit the work to the ThreadPool), and have your main worker thread poll until this inner worker thread triggers a wait state, OR it detects CancellationPending.

You can get at the actual font for the UILabel by recursively examining each of the views starting with the UISegmentedControl. I don't know if this is the best way to do it, but it works.

@interface tmpSegmentedControlTextViewController : UIViewController {
}

@property (nonatomic, assign) IBOutlet UISegmentedControl * theControl;

@end

@implementation tmpSegmentedControlTextViewController

@synthesize theControl; // UISegmentedControl

- (void)viewDidLoad {
  [self printControl:[self theControl]];
  [super viewDidLoad];
}

- (void) printControl:(UIView *) view {
  NSArray * views = [view subviews];
  NSInteger idx,idxMax;
  for (idx = 0, idxMax = views.count; idx < idxMax; idx++) {
    UIView * thisView = [views objectAtIndex:idx];
    UILabel * tmpLabel = (UILabel *) thisView;
    if ([tmpLabel respondsToSelector:@selector(text)]) {
      NSLog(@"TEXT for view %d: %@",idx,tmpLabel.text);
      [tmpLabel setTextColor:[UIColor blackColor]];
    }

    if (thisView.subviews.count) {
      NSLog(@"View has subviews");
      [self printControl:thisView];
    }
  }
}

@end

In the code above I am just setting the text color of the UILabel, but you could grab or set the font property as well I suppose.

Try with this:

          $.ajax({
              type: 'POST',
              url: URL,
              defaultHeaders: {
                  'Content-Type': 'application/json',
                  "Access-Control-Allow-Origin": "*",
                  'Accept': 'application/json'
               },

              data: obj,
              dataType: 'json',
              success: function (response) {
            //    BindTableData();
                console.log("success ");
                alert(response);
              },
              error: function (xhr) {
                console.log("error ");
                console.log(xhr);
              }
          });

( I'm simplifying this a little bit as all but cmp return a value that is both an empty string, and a numerically zero value instead of 0, and a value that is both the string '1' and the numeric value 1. These are the same values you will always get from boolean operators in Perl. You should really only be using the return values for boolean or numeric operations, in which case the difference doesn't really matter. )

Easy! The default should be the first option. Done! That would lead you to unobtrusive JavaScript, because JavaScript isn't needed :)

Unobtrusive JavaScript

InetAddress.getLocalHost().getHostName() is the more portable way.

exec("hostname") actually calls out to the operating system to execute the hostname command.

Here are a couple other related answers on SO:

• Java current machine name and logged in user?
• Get DNS name of local machine as seen by a remote machine

EDIT: You should take a look at A.H.'s answer or Arnout Engelen's answer for details on why this might not work as expected, depending on your situation. As an answer for this person who specifically requested portable, I still think getHostName() is fine, but they bring up some good points that should be considered.

In the interests of helping anyone who lands here but was actually looking for a jQuery free way of doing this:

element.classList.contains('your-class-name')

I ran into this problem . I was checking for version number and enabling the action bar only if it is greater or equal to Honeycomb , but it was returning null. I found the reason and root cause was that I had disabled the Holo Theme style in style.xml under values-v11 folder.

This could be accomplished with a single line of code:

IF OBJECT_ID('tempdb..#tempTableName') IS NOT NULL DROP TABLE #tempTableName;   

An API is ready-made source code library.

In Java for example APIs are a set of related classes and interfaces that come in packages. This picture illustrates the libraries included in the Java Standard Edition API. Packages are denoted by their color.

There used to be a pattern with metaprogramming:

template<unsigned T>
struct Fact {
    enum Enum {
        VALUE = Fact<T-1>*T;
    };
};

template<>
struct Fact<1u> {
    enum Enum {
        VALUE = 1;
    };
};

// Fact<10>::VALUE is known be a compile-time constant

I believe constexpr was introduced to let you write such constructs without the need for templates and weird constructs with specialization, SFINAE and stuff - but exactly like you'd write a run-time function, but with the guarantee that the result will be determined in compile-time.

However, note that:

int fact(unsigned n) {
    if (n==1) return 1;
    return fact(n-1)*n;
}

int main() {
    return fact(10);
}

Compile this with g++ -O3 and you'll see that fact(10) is indeed evaulated at compile-time!

An VLA-aware compiler (so a C compiler in C99 mode or C++ compiler with C99 extensions) may even allow you to do:

int main() {
    int tab[fact(10)];
    int tab2[std::max(20,30)];
}

But that it's non-standard C++ at the moment - constexpr looks like a way to combat this (even without VLA, in the above case). And there's still the problem of the need to have "formal" constant expressions as template arguments.

A FD (functional dependency) that holds in a relation is partial when removing one of the determining attributes gives a FD that holds in the relation. A FD that isn't partial is full.

Eg: If {A,B} ? {C} but also {A} ? {C} then {C} is partially functionally dependent on {A,B}.

Eg: Here's a relation value where that example condition holds. (A FD holds in a relation variable when it holds in every value that can arise.)

A  B  C
1  1  1
1  2  1
2  1  1

The non-trivial FDs that hold: {A,B} determines {C}, {B,C}, {A,C} & {A,B,C}; {A}, {B} & {} also determine {C}. Of those: {A,B} ? {C} is partial per {A} ? {C}, {B} ? {C} & {} ? {C}; {A} ? {C} & {B} ? {C} are partial per {} ? {C}; the others are full.

A functional dependency X ? Y is a full functional dependency if removal of any attribute A from X means that the dependency does not hold any more; that is, for any attribute A e X, (X – {A}) does not functionally determine Y. A functional dependency X ? Y is a partial dependency if some attribute A e X can be removed from X and the dependency still holds; that is, for some A e X, (X – {A}) ? Y.

-- FUNDAMENTALS OF Database Systems SIXTH EDITION Ramez Elmasri & Navathe

Notice that whether a FD is full vs partial doesn't depend on CKs (candidate keys), let alone one CK that you might be calling the PK (primary key).

(A definition of 2NF is that every non-CK attribute is fully functionally determined by every CK. Observe that the only CK is {A,B} & the only non-CK attribute C is partially dependent on it so this value is not in 2NF & indeed it is the lossless join of components/projections onto {A,B} & {A,C}, onto {A,B} & {B,C} & onto {A,B} & {C}.)

(Beware that that textbook's definition of "transitive FD" does not define the same sort of thing as the standard definition of "transitive FD".)

Can you try this, readfile need the full file path.

        $filename='/pdf/jobs/pdffile.pdf';            
        $url_download = BASE_URL . RELATIVE_PATH . $filename;            

        //header("Content-type:application/pdf");   
        header("Content-type: application/octet-stream");                       
        header("Content-Disposition:inline;filename='".basename($filename)."'");            
        header('Content-Length: ' . filesize($filename));
        header("Cache-control: private"); //use this to open files directly                     
        readfile($filename);

If your list has fields/properties and you want to use a specific value (e.g. FirstName), then you can do this:

string combindedString = string.Join( ",", myList.Select(t=>t.FirstName).ToArray() );

If you have another program running in the JVM and you use System.exit, that second program will be closed, too. Imagine for example that you run a java job on a cluster node and that the java program that manages the cluster node runs in the same JVM. If the job would use System.exit it would not only quit the job but also "shut down the complete node". You would not be able to send another job to that cluster node since the management program has been closed accidentally.

Therefore, do not use System.exit if you want to be able to control your program from another java program within the same JVM.

Use System.exit if you want to close the complete JVM on purpose and if you want to take advantage of the possibilities that have been described in the other answers (e.g. shut down hooks: Java shutdown hook, non-zero return value for command line calls: How to get the exit status of a Java program in Windows batch file).

Also have a look at Runtime Exceptions: System.exit(num) or throw a RuntimeException from main?

<context:component-scan base-package="x.y.z"/>

will work since the rest of the packages are sub packages of "x.y.z". Thus, you dont need to mention each package individually.

With ES2018 you can use async iterators:

const asyncFunction = a => fetch(a);
const itemDone = a => console.log(a);

async function example() {
  const arrayOfFetchPromises = [1, 2, 3].map(asyncFunction);

  for await (const item of arrayOfFetchPromises) {
    itemDone(item);
  }

  console.log('All done');
}

this will also work

data.groupby(data['date'].dt.year)

The Newest MySQL Versions have the new BIT data type in which you can specify the number of bits in the field, for example BIT(1) to use as Boolean type, because it can be only 0 or 1.

This was helpful to use in COGNOS because creating a SQL "Not in" statement in Cognos was allowed, but it took too long to run. I had manually coded table A to join to table B in in Cognos as A.key "not in" B.key, but the query was taking too long/not returning results after 5 minutes.

For anyone else that is looking for a "NOT IN" solution in Cognos, here is what I did. Create a Query that joins table A and B with a LEFT JOIN in Cognos by selecting link type: table A.Key has "0 to N" values in table B, then added a Filter (these correspond to Where Clauses) for: table B.Key is NULL.

Ran fast and like a charm.

    $seconds = $duration % 60;

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

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

For some Distributions, Cauchy I think, I have found that trapz will overestimate the area, and so the pdf will change depending on the number of bins you select. In which case I do

[N,h]=hist(q_f./theta,30000); % there Is a large range but most of the bins will be empty
plot(h,N/(sum(N)*mean(diff(h))),'+r')

Just to add to the other answers, the documentation gives this explanation:

• KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

• A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. For all engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL.

• A PRIMARY KEY is a unique index where all key columns must be defined as NOT NULL. If they are not explicitly declared as NOT NULL, MySQL declares them so implicitly (and silently). A table can have only one PRIMARY KEY. The name of a PRIMARY KEY is always PRIMARY, which thus cannot be used as the name for any other kind of index.

Your response object is declared as a ServletResponse. To use the sendRedirect() method, you have to cast it to HttpServletResponse. This is an extended interface that adds methods related to the HTTP protocol.

There is also a combination, you can use a return value with a recordset:

--Stored Procedure--

CREATE PROCEDURE [TestProc]

AS
BEGIN

    DECLARE @Temp TABLE
    (
        [Name] VARCHAR(50)
    )

    INSERT INTO @Temp VALUES ('Mark') 
    INSERT INTO @Temp VALUES ('John') 
    INSERT INTO @Temp VALUES ('Jane') 
    INSERT INTO @Temp VALUES ('Mary') 

    -- Get recordset
    SELECT * FROM @Temp

    DECLARE @ReturnValue INT
    SELECT @ReturnValue = COUNT([Name]) FROM @Temp

    -- Return count
    RETURN @ReturnValue

END

--Calling Code--

DECLARE @SelectedValue int
EXEC @SelectedValue = [TestProc] 

SELECT @SelectedValue

--Results--

Common cases where a surrogate AUTO_INCREMENT hurts:

A common schema pattern is a many-to-many mapping:

CREATE TABLE map (
    id ... AUTO_INCREMENT,
    foo_id ...,
    bar_id ...,
    PRIMARY KEY(id),
    UNIQUE(foo_id, bar_id),
    INDEX(bar_id) );

Performance of this pattern is much better, especially when using InnoDB:

CREATE TABLE map (
    # No surrogate
    foo_id ...,
    bar_id ...,
    PRIMARY KEY(foo_id, bar_id),
    INDEX      (bar_id, foo_id) );

Why?

• InnoDB secondary keys need an extra lookup; by moving the pair into the PK, that is avoided for one direction.
• The secondary index is "covering", so it does not need the extra lookup.
• This table is smaller because of getting rid of id and one index.

Another case (country):

country_id INT ...
-- versus
country_code CHAR(2) CHARACTER SET ascii

All too often the novice normalizes country_code into a 4-byte INT instead of using a 'natural' 2-byte, nearly-unchanging 2-byte string. Faster, smaller, fewer JOINs, more readable.

Try opening Port 3306, and using that in the connection string not 8080.

Also, name it divrat.m, not divrat.M. This shouldn't matter on most OSes, but who knows...

You can also test whether matlab can find a function by using the which command, i.e.

which divrat

The multiplier is changed at every coordinate because of the great circle distance theory as written here :

http://en.wikipedia.org/wiki/Great-circle_distance

and you can calculate the nearest value using this formula described here:

http://en.wikipedia.org/wiki/Great-circle_distance#Worked_example

the key is converting each degree - minute - second value to all degree value:

N 36°7.2', W 86°40.2'  N = (+) , W = (-), S = (-), E = (+) 
referencing the Greenwich meridian and Equator parallel

(phi)     36.12° = 36° + 7.2'/60' 

(lambda)  -86.67° = 86° + 40.2'/60'

First use pkill or kill -9 <pid> to kill the process.

Then use following userdel command to delete user,

userdel -f cafe_fixer

According to userdel man page:

-f, --force

This option forces the removal of the user account, even if the user is still logged in. It also forces userdel to remove the user's home directory and mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user. If USERGROUPS_ENAB is defined to yes in /etc/login.defs and if a group exists with the same name as the deleted user, then this group will be removed, even if it is still the primary group of another user.

Edit 1: (by @Ajedi32)

Note: This option (i.e. --force) is dangerous and may leave your system in an inconsistent state.

Edit 2: (by @socketpair)

In spite of the description about some files, this key allows removing the user while it is in use. Don't forget to chdir / before, because this command will also remove home directory.

Your question almost spells the SQL for this:

DELETE FROM table WHERE id IN (1, 4, 6, 7)

Allow an analysis.

#include <iostream>   // not #include "iostream"
using namespace std;  // in this case okay, but never do that in header files

class A
{
 public:
  void f() { cout<<"f()\n"; }
};

int main()
{
 /*
 // A a; //this works
 A *a = new A(); //this doesn't
 a.f(); // "f has not been declared"
 */ // below


 // system("pause");  <-- Don't do this. It is non-portable code. I guess your 
 //                       teacher told you this?
 //                       Better: In your IDE there is prolly an option somewhere
 //                               to not close the terminal/console-window.
 //                       If you compile on a CLI, it is not needed at all.
}

As a general advice:

0) Prefer automatic variables
  int a;
  MyClass myInstance;
  std::vector<int> myIntVector;

1) If you need data sharing on big objects down 
   the call hierarchy, prefer references:

  void foo (std::vector<int> const &input) {...}
  void bar () { 
       std::vector<int> something;
       ...
       foo (something);
  }


2) If you need data sharing up the call hierarchy, prefer smart-pointers
   that automatically manage deletion and reference counting.

3) If you need an array, use std::vector<> instead in most cases.
   std::vector<> is ought to be the one default container.

4) I've yet to find a good reason for blank pointers.

   -> Hard to get right exception safe

       class Foo {
           Foo () : a(new int[512]), b(new int[512]) {}
           ~Foo() {
               delete [] b;
               delete [] a;
           }
       };

       -> if the second new[] fails, Foo leaks memory, because the
          destructor is never called. Avoid this easily by using 
          one of the standard containers, like std::vector, or
          smart-pointers.

As a rule of thumb: If you need to manage memory on your own, there is generally a superiour manager or alternative available already, one that follows the RAII principle.

Use window.open():

<a onclick="window.open(document.URL, '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');">
  Share Page
</a>

This will create a link titled Share Page which opens the current url in a new window with a height of 570 and width of 520.

You can use itertools.cycle:

>>> from itertools import cycle
>>> lis = [[10,13,17],[3,5,1],[13,11,12]]
>>> cyc = cycle((-1, 1))
>>> 50 + sum(x*next(cyc) for x in lis[0])   # lis[0] is [10,13,17]
36

Here the generator expression inside sum would return something like this:

>>> cyc = cycle((-1, 1))
>>> [x*next(cyc) for x in lis[0]]
[-10, 13, -17]

You can also use zip here:

>>> cyc = cycle((-1, 1))
>>> [x*y for x, y  in zip(lis[0], cyc)]
[-10, 13, -17]

1. Access operator applicable to (a) all pointer types, (b) all types which explicitely overload this operator

2. Introducer for the return type of a local lambda expression:

   std::vector<MyType> seq;
   // fill with instances...  
   std::sort(seq.begin(), seq.end(),
               [] (const MyType& a, const MyType& b) -> bool {
                   return a.Content < b.Content;
               });
   

3. introducing a trailing return type of a function in combination of the re-invented auto:

   struct MyType {
       // declares a member function returning std::string
       auto foo(int) -> std::string;
   };
   

This works if you just want the count of unique values in e.g. the following range

=counta(unique(B4:B21))

Do this -> chmod +w ~/.ssh/known_hosts. This adds write permission to the file at ~/.ssh/known_hosts. After that the remote host will be added to the known_hosts file when you connect to it the next time.

To start you off on your assignment, String.split splits strings on a regular expression and this expression may be an empty string:

String[] ary = "abc".split("");

Yields the array:

(java.lang.String[]) [, a, b, c]

Getting rid of the empty 1st entry is left as an exercise for the reader :-)

Note: In Java 8, the empty first element is no longer included.

Following CSS worked for me:

/* newline before element */
#myelementId:before{
    content:"\a";
    white-space: pre;
}

public static string ComputeSHA256Hash(string text)
{
    using (var sha256 = new SHA256Managed())
    {
        return BitConverter.ToString(sha256.ComputeHash(Encoding.UTF8.GetBytes(text))).Replace("-", "");
    }                
}

The reason why you get different results is because you don't use the same string encoding. The link you put for the on-line web site that computes SHA256 uses UTF8 Encoding, while in your example you used Unicode Encoding. They are two different encodings, so you don't get the same result. With the example above you get the same SHA256 hash of the linked web site. You need to use the same encoding also in PHP.

if(is_array($arr) && count($arr) > 1)

Just to be sure that $arr is indeed an array.

sizeof is an alias of count, I prefer to use count because:

1. 1 less character to type
2. sizeof at a quick glance might mean a size of an array in terms of memory, too technical :(

The problem here is much more complex than removing the container padding since the grid structure relies on this padding when applying negative margins for the enclosed rows.

Removing the container padding in this case will cause an x-axis overflow caused by all the rows inside of this container class, this is one of the most stupid things about the Bootstrap Grid.

Logically it should be approached by

1. Never using the .container class for anything other than rows
2. Make a clone of the .container class that has no padding for use with non-grid html
3. For removing the .container padding on mobile you can manually remove it with media queries then overflow-x: hidden; which is not very reliable but works in most cases.

If you are using LESS the end result will look like this

@media (max-width: @screen-md-max) {
    .container{
        padding: 0;
        overflow-x: hidden;
    }
}

Change the media query to whatever size you want to target.

Final thoughts, I would highly recommend using the Foundation Framework Grid as its way more advanced

If you use Mozilla Firefox, It will work as expected without any issues;

P.S. Surprisingly, IntenetExplorer_Edge works absolutely fine!!!

Does the DB know the connection has dropped, or is the session still listed in v$session? That would indicate, I think, that it's being dropped by the network. Do you know how long it can stay idle before encountering the problem, and if that bears any resemblance to the TCP idle values (net.ipv4.tcp_keepalive_time, tcp_keepalive_probes and tcp_keepalive_interval from sysctl if I recall correctly)? Can't remember whether sysctl changes persist by default, but that might be something that was modified and then reset by the reboot.

Also you might be able to reset your JDBC connections without bouncing the whole server; certainly can in WebLogic, which I realise doesn't help much, but I'm not familiar with the Tomcat equivalents.

foreach can handle arrays and objects. You can check this with:

$can_foreach = is_array($var) || is_object($var);
if ($can_foreach) {
    foreach ($var as ...
}

You don't need to specifically check for Traversable as others have hinted it in their answers, because all objects - like all arrays - are traversable in PHP.

More technically:

foreach works with all kinds of traversables, i.e. with arrays, with plain objects (where the accessible properties are traversed) and Traversable objects (or rather objects that define the internal get_iterator handler).

(source)

Simply said in common PHP programming, whenever a variable is

• an array
• an object

and is not

• NULL
• a resource
• a scalar

you can use foreach on it.

There is another cause for this type of problem what I would like to share, because I struggle in this problem for some time and I could't find any answer on SO.

In a repository like:

@Repository
public interface UserEntityDao extends CrudRepository<UserEntity, Long>{

}

If your entity UserEntity does not have the @Entity annotation on the class, you will have the same error.

This error is confusing for this case, because you focus on trying to resolve the problem about Spring not found the Repository but the problem is the entity. And if you came to this answer trying to test your Repository, this answer may help you.

The key difference: NSMutableDictionary can be modified in place, NSDictionary cannot. This is true for all the other NSMutable* classes in Cocoa. NSMutableDictionary is a subclass of NSDictionary, so everything you can do with NSDictionary you can do with both. However, NSMutableDictionary also adds complementary methods to modify things in place, such as the method setObject:forKey:.

You can convert between the two like this:

NSMutableDictionary *mutable = [[dict mutableCopy] autorelease];
NSDictionary *dict = [[mutable copy] autorelease]; 

Presumably you want to store data by writing it to a file. NSDictionary has a method to do this (which also works with NSMutableDictionary):

BOOL success = [dict writeToFile:@"/file/path" atomically:YES];

To read a dictionary from a file, there's a corresponding method:

NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:@"/file/path"];

If you want to read the file as an NSMutableDictionary, simply use:

NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:@"/file/path"];

The Host property will return the domain name you used when accessing the site. So, in your development environment, since you're requesting

http://localhost:950/m/pages/Searchresults.aspx?search=knife&filter=kitchen

It's returning localhost. You can break apart your URL like so:

Protocol: http
Host: localhost
Port: 950
PathAndQuery: /m/pages/SearchResults.aspx?search=knight&filter=kitchen

For anyone else coming across this thread I had this issue and was pulling my hair out. I had the service declaration OUTSIDE of the '< application>' end tag DUH!

RIGHT:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  ...>
...
<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity ...>
        ...
    </activity>    

    <service android:name=".Service"/>

    <receiver android:name=".Receiver">
        <intent-filter>
            ...
        </intent-filter>
    </receiver>        
</application>

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

WRONG but still compiles without errors:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  ...>
...
<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity ...>
        ...
    </activity>

</application>

    <service android:name=".Service"/>

    <receiver android:name=".Receiver">
        <intent-filter>
            ...
        </intent-filter>
    </receiver>        

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

Just another way of doing it.

I had the same problem using special characters as delimiters on JSP. When the special characters got posted to the servlet, they all got messed up. I solved the issue by using the following conversion:

String str = new String (request.getParameter("string").getBytes ("iso-8859-1"), "UTF-8");

file_name=test.log

# set first K lines:
K=1000

# line count (N): 
N=$(wc -l < $file_name)

# length of the bottom file:
L=$(( $N - $K ))

# create the top of file: 
head -n $K $file_name > top_$file_name

# create bottom of file: 
tail -n $L $file_name > bottom_$file_name

Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so

split -l 300000 file_name

will output xaa with 300k lines and xab with 100k lines, for an input with 400k lines.

sed -n 's/^potato:[[:space:]]*//p' file.txt

One can think of Grep as a restricted Sed, or of Sed as a generalized Grep. In this case, Sed is one good, lightweight tool that does what you want -- though, of course, there exist several other reasonable ways to do it, too.

Another approach is to use a reverse proxy, which allows you to view Tensorboard from any internet connected device without SSHing. This approach can make it far easier / tractable to view Tensorboard on mobile devices, for example.

Steps:

1) Download reverse proxy Ngrok on your remote machine hosting Tensorboard. See https://ngrok.com/download for instructions (~5 minute setup).

2) Run ngrok http 6006 (assuming you're hosting Tensorboard on port 6006)

3) Save the URL that ngrok outputs:

4) Enter that into any browser to view TensorBoard:

If you don't want to group your result, use a window function.

You didn't state your DBMS, but this is ANSI SQL:

SELECT AccountNumber, 
       Bill, 
       BillDate, 
       SUM(Bill) over (partition by accountNumber) as account_total
FROM Table1
order by AccountNumber, BillDate;

Here is an SQLFiddle: http://sqlfiddle.com/#!15/2c35e/1

You can even add a running sum, by adding:

sum(bill) over (partition by account_number order by bill_date) as sum_to_date

which will give you the total up to the current's row date.

This should do the work

import datetime
datetime.datetime.now().strftime("%H:%M:%S.%f")

It will print

HH:MM:SS.microseconds like this e.g 14:38:19.425961

@FunctionalInterface annotation is useful for compilation time checking of your code. You cannot have more than one method besides static, default and abstract methods that override methods in Object in your @FunctionalInterface or any other interface used as a functional interface.

But you can use lambdas without this annotation as well as you can override methods without @Override annotation.

From docs

a functional interface has exactly one abstract method. Since default methods have an implementation, they are not abstract. If an interface declares an abstract method overriding one of the public methods of java.lang.Object, that also does not count toward the interface's abstract method count since any implementation of the interface will have an implementation from java.lang.Object or elsewhere

This can be used in lambda expression:

public interface Foo {
  public void doSomething();
}

This cannot be used in lambda expression:

public interface Foo {
  public void doSomething();
  public void doSomethingElse();
}

But this will give compilation error:

@FunctionalInterface
public interface Foo {
  public void doSomething();
  public void doSomethingElse();
}

Invalid '@FunctionalInterface' annotation; Foo is not a functional interface

I don't think that there are any neat tricks you can do storing this as you can do for example with an MD5 hash.

I think your best bet is to store it as a CHAR(60) as it is always 60 chars long

Compare document.activeElement with the element you want to check for focus. If they are the same, the element is focused; otherwise, it isn't.

// dummy element
var dummyEl = document.getElementById('myID');

// check for focus
var isFocused = (document.activeElement === dummyEl);

hasFocus is part of the document; there's no such method for DOM elements.

Also, document.getElementById doesn't use a # at the beginning of myID. Change this:

var dummyEl = document.getElementById('#myID');

to this:

var dummyEl = document.getElementById('myID');

If you'd like to use a CSS query instead you can use querySelector (and querySelectorAll).

Problem

There seems to be a problem with the original "duplicate line down" shortcut on Ubuntu, mostly due to a conflict with an already existing workspace related shortcut on the operating system.

Workaround

However, an easy workaround is to simply ctrl+c (copies the entire line) and ctrl+v (pastes the copied line on to a new one)... Effectively, giving you the same end result.

Just for the sake of completion: when parsing a date using strptime() and the date contains the name of a day, month, etc, be aware that you have to account for the locale.

It's mentioned as a footnote in the docs as well.

As an example:

import locale
print(locale.getlocale())

>> ('nl_BE', 'ISO8859-1')

from datetime import datetime
datetime.strptime('6-Mar-2016', '%d-%b-%Y').strftime('%Y-%m-%d')

>> ValueError: time data '6-Mar-2016' does not match format '%d-%b-%Y'

locale.setlocale(locale.LC_ALL, 'en_US')
datetime.strptime('6-Mar-2016', '%d-%b-%Y').strftime('%Y-%m-%d')

>> '2016-03-06'

Yes, it's possible, e.g. using the implicit conversion from RAW to BLOB:

insert into blob_fun values(1, hextoraw('453d7a34'));

453d7a34 is a string of hexadecimal values, which is first explicitly converted to the RAW data type and then inserted into the BLOB column. The result is a BLOB value of 4 bytes.

Instead of a comment, I just want to answer post.

Interface java.sql.PreparedStatement

1. columnIndexes « You can use prepareStatement function that accepts columnIndexes and SQL statement. Where columnIndexes allowed constant flags are Statement.RETURN_GENERATED_KEYS1 or Statement.NO_GENERATED_KEYS[2], SQL statement that may contain one or more '?' IN parameter placeholders.

   SYNTAX «

   Connection.prepareStatement(String sql, int autoGeneratedKeys)
   Connection.prepareStatement(String sql, int[] columnIndexes)
   

   Example:

   PreparedStatement pstmt = 
       conn.prepareStatement( insertSQL, Statement.RETURN_GENERATED_KEYS );
   

2. columnNames « List out the columnNames like 'id', 'uniqueID', .... in the target table that contain the auto-generated keys that should be returned. The driver will ignore them if the SQL statement is not an INSERT statement.

   SYNTAX «

   Connection.prepareStatement(String sql, String[] columnNames)
   

   Example:

   String columnNames[] = new String[] { "id" };
   PreparedStatement pstmt = conn.prepareStatement( insertSQL, columnNames );
   

Full Example:

public static void insertAutoIncrement_SQL(String UserName, String Language, String Message) {
    String DB_URL = "jdbc:mysql://localhost:3306/test", DB_User = "root", DB_Password = "";

    String insertSQL = "INSERT INTO `unicodeinfo`( `UserName`, `Language`, `Message`) VALUES (?,?,?)";
            //"INSERT INTO `unicodeinfo`(`id`, `UserName`, `Language`, `Message`) VALUES (?,?,?,?)";
    int primkey = 0 ;
    try {
        Class.forName("com.mysql.jdbc.Driver").newInstance();
        Connection conn = DriverManager.getConnection(DB_URL, DB_User, DB_Password);

        String columnNames[] = new String[] { "id" };

        PreparedStatement pstmt = conn.prepareStatement( insertSQL, columnNames );
        pstmt.setString(1, UserName );
        pstmt.setString(2, Language );
        pstmt.setString(3, Message );

        if (pstmt.executeUpdate() > 0) {
            // Retrieves any auto-generated keys created as a result of executing this Statement object
            java.sql.ResultSet generatedKeys = pstmt.getGeneratedKeys();
            if ( generatedKeys.next() ) {
                primkey = generatedKeys.getInt(1);
            }
        }
        System.out.println("Record updated with id = "+primkey);
    } catch (InstantiationException | IllegalAccessException | ClassNotFoundException | SQLException e) {
        e.printStackTrace();
    }
}

Well, first off, the ^ operator in C/C++ is the bit-wise XOR. It has nothing to do with powers.

Now, regarding your problem with using the pow() function, some googling shows that casting one of the arguments to double helps:

result = (int) pow((double) a,i);

Note that I also cast the result to int as all pow() overloads return double, not int. I don't have a MS compiler available so I couldn't check the code above, though.

Since C99, there are also float and long double functions called powf and powl respectively, if that is of any help.

What you need, according to your comments, is a 'BLOB' (Binary Large OBject) for both image and resume.

Just replace below statement and it will work.

SimpleDateFormat formatDate = new SimpleDateFormat("hh:mm a");

Another intuitive solution could be:

class Post
{
    public $title;
    public $date;
}

$posts = array();

$posts[0] = new Post();
$posts[0]->title = 'post sample 1';
$posts[0]->date = '1/1/2021';

$posts[1] = new Post();
$posts[1]->title = 'post sample 2';
$posts[1]->date = '2/2/2021';

foreach ($posts as $post) {
  echo 'Post Title:' . $post->title . ' Post Date:' . $post->date . "\n";
}

I was same problem, but for me the problem was ng build command. I was doing "ng build --prod" i have corrected it to "ng build --prod --base-href /applicationname/". and this solved my problem.

if you execute

mvn eclipse:clean

followed by

mvn eclipse:eclipse

if will prepare the eclipse .classpath file for you. That is, these commands are run against maven from the command line i.e. outside of eclipse.

One simple answer with build in native Node module.(No third party npm modules)

The querystring module provides utilities for parsing and formatting URL query strings. It can be accessed using:

const querystring = require('querystring');

const body = "abc=foo&def=%5Basf%5D&xyz=5"
const parseJSON = querystring.parse(body);
console.log(parseJSON);

See example.

/**
 * nv_get_plaintext()
 *
 * @param mixed $string
 * @return
 */
function nv_get_plaintext( $string, $keep_image = false, $keep_link = false )
{
    // Get image tags
    if( $keep_image )
    {
        if( preg_match_all( "/\<img[^\>]*src=\"([^\"]*)\"[^\>]*\>/is", $string, $match ) )
        {
            foreach( $match[0] as $key => $_m )
            {
                $textimg = '';
                if( strpos( $match[1][$key], 'data:image/png;base64' ) === false )
                {
                    $textimg = " " . $match[1][$key];
                }
                if( preg_match_all( "/\<img[^\>]*alt=\"([^\"]+)\"[^\>]*\>/is", $_m, $m_alt ) )
                {
                    $textimg .= " " . $m_alt[1][0];
                }
                $string = str_replace( $_m, $textimg, $string );
            }
        }
    }

    // Get link tags
    if( $keep_link )
    {
        if( preg_match_all( "/\<a[^\>]*href=\"([^\"]+)\"[^\>]*\>(.*)\<\/a\>/isU", $string, $match ) )
        {
            foreach( $match[0] as $key => $_m )
            {
                $string = str_replace( $_m, $match[1][$key] . " " . $match[2][$key], $string );
            }
        }
    }

    $string = str_replace( ' ', ' ', strip_tags( $string ) );
    return preg_replace( '/[ ]+/', ' ', $string );
}

Change column position:

ALTER TABLE Employees 
   CHANGE empName empName VARCHAR(50) NOT NULL AFTER department;

If you need to move it to the first position you have to use term FIRST at the end of ALTER TABLE CHANGE [COLUMN] query:

ALTER TABLE UserOrder 
   CHANGE order_id order_id INT(11) NOT NULL FIRST;

UPDATE: According to some comments, the solution in the original answer does not seem to work under certain scenarios in iOS 8+. I can't verify that that is actually the case without further details.

For those of you however in that situation there's an alternative. Detecting when a view controller is being popped is possible by overriding willMove(toParentViewController:). The basic idea is that a view controller is being popped when parent is nil.

Check out "Implementing a Container View Controller" for further details.

Since iOS 5 I've found that the easiest way of dealing with this situation is using the new method - (BOOL)isMovingFromParentViewController:

- (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];

  if (self.isMovingFromParentViewController) {
    // Do your stuff here
  }
}

- (BOOL)isMovingFromParentViewController makes sense when you are pushing and popping controllers in a navigation stack.

However, if you are presenting modal view controllers you should use - (BOOL)isBeingDismissed instead:

- (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];

  if (self.isBeingDismissed) {
    // Do your stuff here
  }
}

As noted in this question, you could combine both properties:

- (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];

  if (self.isMovingFromParentViewController || self.isBeingDismissed) {
    // Do your stuff here
  }
}

Other solutions rely on the existence of a UINavigationBar. Instead like my approach more because it decouples the required tasks to perform from the action that triggered the event, i.e. pressing a back button.

There isn't currently a built-in PowerShell method for doing the SFTP part. You'll have to use something like psftp.exe or a PowerShell module like Posh-SSH.

Here is an example using Posh-SSH:

# Set the credentials
$Password = ConvertTo-SecureString 'Password1' -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ('root', $Password)

# Set local file path, SFTP path, and the backup location path which I assume is an SMB path
$FilePath = "C:\FileDump\test.txt"
$SftpPath = '/Outbox'
$SmbPath = '\\filer01\Backup'

# Set the IP of the SFTP server
$SftpIp = '10.209.26.105'

# Load the Posh-SSH module
Import-Module C:\Temp\Posh-SSH

# Establish the SFTP connection
$ThisSession = New-SFTPSession -ComputerName $SftpIp -Credential $Credential

# Upload the file to the SFTP path
Set-SFTPFile -SessionId ($ThisSession).SessionId -LocalFile $FilePath -RemotePath $SftpPath

#Disconnect all SFTP Sessions
Get-SFTPSession | % { Remove-SFTPSession -SessionId ($_.SessionId) }

# Copy the file to the SMB location
Copy-Item -Path $FilePath -Destination $SmbPath

Some additional notes:

• You'll have to download the Posh-SSH module which you can install to your user module directory (e.g. C:\Users\jon_dechiro\Documents\WindowsPowerShell\Modules) and just load using the name or put it anywhere and load it like I have in the code above.
• If having the credentials in the script is not acceptable you'll have to use a credential file. If you need help with that I can update with some details or point you to some links.
• Change the paths, IPs, etc. as needed.

That should give you a decent starting point.

You haven't specified the absolute path - you've used a shortcut , ~, which might not work in this context. Use /home/yourusername/Harold-Server/OmniCloud.db instead.

I found emailonacid.com today (beta, currently free†) - have only played with it a little but so far so good. It simulates the following clients:

• AOL 9
• Entourage 2004 & 2008
• Gmail
• Hotmail
• Windows Live Mail
• Windows Mail
• Mac Mail
• Outlook 2003 & 2007
• Thunderbird 2, 3 & Beta
• Yahoo Classic / Yahoo Mail

The very helpful thing about this service is it tells you what code is not supported in which client.

First you have to download file x-plore and installed it.. After that open it and find the thoes you want to edit.. After that just rename the file Xyz.apk to xyz.zip After that open that file and you can see some folders.. then just go and edit the app..

How to create symlink in vagrant. Steps:

1. In vagrant file create a synced folder. e.g config.vm.synced_folder "F:/Sunburst/source/sunburst/lms", "/source" F:/Sunburst/source/sunburst/lms :- where the source code, /source :- directory path inside the vagrant
2. Vagrant up and type vagrant ssh and go to source directory e.g cd source
3. Verify your source code folder structure is available in the source directory. e.g /source/local
4. Then go to the guest machine directory where the files which are associate with the browser. After get backup of the file. e.g sudo mv local local_bk
5. Then create symlink e.g sudo ln -s /source/local local. local mean link-name (folder name in guest machine which you are going to link) if you need to remove the symlink :- Type sudo rm local

You can remove .selected from saveUsername in your checkbox input since saveUsername is a boolean. Instead of [(ngModel)] use [checked]="saveUsername" (change)="saveUsername = !saveUsername"

Edit: Correct Solution:

<input
  type="checkbox"
  [checked]="saveUsername"
  (change)="saveUsername = !saveUsername"/>

Update: Like @newman noticed when ngModel is used in a form it won't work. However, you should use [ngModelOptions] attribute like (tested in Angular 7):

<input
  type="checkbox"
  [(ngModel)]="saveUsername"
  [ngModelOptions]="{standalone: true}"/> `

I also created an example at Stackblitz: https://stackblitz.com/edit/angular-abelrm

1. Download gecko driver from the seleniumhq website (Now it is on GitHub and you can download it from Here) .
   2. You will have a zip (or tar.gz) so extract it.
   3. After extraction you will have geckodriver.exe file (appropriate executable in linux).
   4. Create Folder in C: named SeleniumGecko (Or appropriate)
   5. Copy and Paste geckodriver.exe to SeleniumGecko
   6. Set the path for gecko driver as below

.

System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.10.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();

Yes. It is possible for overridden methods to have different return type .

But the limitations are that the overridden method must have a return type that is more specific type of the return type of the actual method.

All the answers have given examples of the overridden method to have a return type which is a subclass of the return type of the actual method.

For example :

public class Foo{

   //method which returns Foo
  Foo getFoo(){
      //your code         
  }

}

 public class subFoo extends Foo{

  //Overridden method which returns subclass of Foo
  @Override
  subFoo getFoo(){
      //your code         
  }

}

But this is not only limited to subclass.Even classes that implement an interface are a specific type of the interface and thus can be a return type where the interface is expected.

For example :

public interface Foo{

   //method which returns Foo
  Foo getFoo();

}

 public class Fizz implements Foo{

  //Overridden method which returns Fizz(as it implements Foo)
  @Override
  Fizz getFoo(){
      //your code         
  }

}

#include <stdio.h>
#include <conio.h>
int main()
{
    int i,j;
    int b=0;
    for (i=2;i<=100;i++){
        for (j=2;j<=i;j++){
            if (i%j==0){
                break;
            }
        }
        if (i==j)
            print f("\n%d",j);
    }
    getch ();
}

The method below returns only the files with certain extension (eg: file with .txt but not .txt1)

public static IEnumerable<string> GetFilesByExtension(string directoryPath, string extension, SearchOption searchOption)
    {
        return
            Directory.EnumerateFiles(directoryPath, "*" + extension, searchOption)
                .Where(x => string.Equals(Path.GetExtension(x), extension, StringComparison.InvariantCultureIgnoreCase));
    }

Short answer: mathematically speaking, no, in practical terms, yes, for example for Intentional Programming.

Technically, the answer would be "no, it's not needed" because it's expressible using other constructs. But in practice, I use for i in range(len(a) (or for _ in range(len(a)) if I don't need the index) to make it explicit that I want to iterate as many times as there are items in a sequence without needing to use the items in the sequence for anything.

So: "Is there a need?"? — yes, I need it to express the meaning/intent of the code for readability purposes.

See also: https://en.wikipedia.org/wiki/Intentional_programming

And obviously, if there is no collection that is associated with the iteration at all, for ... in range(len(N)) is the only option, so as to not resort to i = 0; while i < N; i += 1 ...

According to the most viable answer the suggestion is to use "isBeforeFirst()". That's not the best solution if you don't have a "forward only type".

There's a method called ".first()". It's less overkill to get the exact same result. You check whether there is something in your "resultset" and don't advance your cursor.

The documentation states: "(...) false if there are no rows in the result set".

if(rs.first()){
    //do stuff      
}

You can also just call isBeforeFirst() to test if there are any rows returned without advancing the cursor, then proceed normally. – SnakeDoc Sep 2 '14 at 19:00

However, there's a difference between "isBeforeFirst()" and "first()". First generates an exception if done on a resultset from type "forward only".

Compare the two throw sections: http://docs.oracle.com/javase/7/docs/api/java/sql/ResultSet.html#isBeforeFirst() http://docs.oracle.com/javase/7/docs/api/java/sql/ResultSet.html#first()

Okay, basically this means that you should use "isBeforeFirst" as long as you have a "forward only" type. Otherwise it's less overkill to use "first()".
