I realize this post is a few years old, but I just wanted to extend this to anyone still struggling through this issue.

The company I work for still uses VS2015 so in turn I still use VS2015. I recently started working on a RPC application using C++ and found the need to download the Win32 Templates. Like many others I was having this "SDK 8.1 was not found" issue. i took the following corrective actions with no luck.

• I found the SDK through Micrsoft at the following link https://developer.microsoft.com/en-us/windows/downloads/sdk-archive/ as referenced above and downloaded it.
• I located my VS2015 install in Apps & Features and ran the repair.
• I completely uninstalled my VS2015 and reinstalled it.
• I attempted to manually point my console app "Executable" and "Include" directories to the C:\Program Files (x86)\Microsoft SDKs\Windows Kits\8.1 and C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools.

None of the attempts above corrected the issue for me...

I then found this article on social MSDN https://social.msdn.microsoft.com/Forums/office/en-US/5287c51b-46d0-4a79-baad-ddde36af4885/visual-studio-cant-find-windows-81-sdk-when-trying-to-build-vs2015?forum=visualstudiogeneral

Finally what resolved the issue for me was:

• Uninstalling and reinstalling VS2015.
• Locating my installed "Windows Software Development Kit for Windows 8.1" and running the repair.
• Checked my "C:\Program Files (x86)\Microsoft SDKs\Windows Kits\8.1" to verify the "DesignTime" folder was in fact there.
• Opened VS created a Win32 Console application and comiled with no errors or issues

I hope this saves anyone else from almost 3 full days of frustration and loss of productivity.

Simplest way is to cast the Object to any, like this:

const data = {"Ticket-1.pdf":"8e6e8255-a6e9-4626-9606-4cd255055f71.pdf","Ticket-2.pdf":"106c3613-d976-4331-ab0c-d581576e7ca1.pdf"};
const obj = <any>Object;
const values = obj.values(data).map(x => x.substr(0, x.length - 4));
const commaJoinedValues = values.join(',');
console.log(commaJoinedValues);

And voila – no compilation errors ;)

If the problem is not solved by above answer, check whether the Windows SDK version is 10.0.15063.0.

Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0

After this rebuild the solution.  

Quick solution that worked like a charm for me and others:

If you are using VS 2015+, just remove the following lines from the .csproj file of your project:

  <Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
  <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
  </Target>

In VS 2015+ Solution Explorer:

1. Right-click project name -> Unload Project
2. Right-click project name -> Edit .csproj
3. Remove the lines specified above from the file and save
4. Right-click project name -> Reload Project

For me, adding Trusted_Connection=True to the connection string helped.

In the constructor of

 public class ErrorEventArg : EventArgs

You have to add "base" as follows:

    public ErrorEventArg(string errorMsg, string lastQuery) : base (string errorMsg, string lastQuery)
    {
        ErrorMsg = errorMsg;
        LastQuery = lastQuery;
    }

That solved it for me

I faced the same problem too and I found out that I selected "new Win32 application" instead of "new Win32 console application". Problem solved when I switched. Hope this can help you.

Try to

1. Clean Solution
2. Rebuild Solution

Edit filename: core/Common.php, line number: 257

Before

return $_config[0] =& $config; 

After

$_config[0] =& $config;
return $_config[0]; 

Update

Added by NikiC

In PHP assignment expressions always return the assigned value. So $_config[0] =& $config returns $config - but not the variable itself, but a copy of its value. And returning a reference to a temporary value wouldn't be particularly useful (changing it wouldn't do anything).

Update

This fix has been merged into CI 2.2.1 (https://github.com/bcit-ci/CodeIgniter/commit/69b02d0f0bc46e914bed1604cfbd9bf74286b2e3). It's better to upgrade rather than modifying core framework files.

You can specify esversion:6 inside jshint options object. Please see the image. I am using grunt-contrib-jshint plugin.

Run

cordova -v 

to see the currently running version. Run the npm info command

npm info cordova

for a longer listing that includes the current version along with other available version numbers

This example program illustrates initialization of an array of C strings.

#include <stdio.h>

const char * array[] = {
    "First entry",
    "Second entry",
    "Third entry",
};

#define n_array (sizeof (array) / sizeof (const char *))

int main ()
{
    int i;

    for (i = 0; i < n_array; i++) {
        printf ("%d: %s\n", i, array[i]);
    }
    return 0;
}

It prints out the following:

0: First entry
1: Second entry
2: Third entry

using System;
using System.Linq;
using MySql.Data.MySqlClient;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            // add here your connection details
            String connectionString = "Server=localhost;Database=database;Uid=username;Pwd=password;";
            try
            {
                MySqlConnection connection = new MySqlConnection(connectionString);
                connection.Open();

                Console.WriteLine("MySQL version: " + connection.ServerVersion);
                connection.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex);
            }
            Console.ReadKey();
        }
    }
}

make sure your database server is running if its not running then its not able to make connection and bydefault mysql running on 3306 so don't need mention port if same in case of port number is different then we need to mention port

You need to map attributes to aesthetics (colours within the aes statement) to produce a legend.

cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h, fill = "BAR"),colour="#333333")+ #green
  geom_line(aes(y=b,group=1, colour="LINE1"),size=1.0) +   #red
  geom_point(aes(y=b, colour="LINE1"),size=3) +           #red
  geom_errorbar(aes(ymin=d, ymax=e, colour="LINE1"), width=0.1, size=.8) + 
  geom_line(aes(y=c,group=1,colour="LINE2"),size=1.0) +   #blue 
  geom_point(aes(y=c,colour="LINE2"),size=3) +           #blue
  geom_errorbar(aes(ymin=f, ymax=g,colour="LINE2"), width=0.1, size=.8) + 
  scale_colour_manual(name="Error Bars",values=cols) + scale_fill_manual(name="Bar",values=cols) +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

I understand where Roland is coming from, but since this is only 3 attributes, and complications arise from superimposing bars and error bars this may be reasonable to leave the data in wide format like it is. It could be slightly reduced in complexity by using geom_pointrange.

To change the background color for the error bars legend in the original, add + theme(legend.key = element_rect(fill = "white",colour = "white")) to the plot specification. To merge different legends, you typically need to have a consistent mapping for all elements, but it is currently producing an artifact of a black background for me. I thought guide = guide_legend(fill = NULL,colour = NULL) would set the background to null for the legend, but it did not. Perhaps worth another question.

ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR", colour="BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1"),size=1.0) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=3) +           #red
  geom_errorbar(aes(ymin=d, ymax=e, colour="LINE1"), width=0.1, size=.8) + 
  geom_line(aes(y=c,group=1,colour="LINE2"),size=1.0) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=3) +           #blue
  geom_errorbar(aes(ymin=f, ymax=g,colour="LINE2"), width=0.1, size=.8) + 
  scale_colour_manual(name="Error Bars",values=cols, guide = guide_legend(fill = NULL,colour = NULL)) + 
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

To get rid of the black background in the legend, you need to use the override.aes argument to the guide_legend. The purpose of this is to let you specify a particular aspect of the legend which may not be being assigned correctly.

ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR", colour="BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1"),size=1.0) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=3) +           #red
  geom_errorbar(aes(ymin=d, ymax=e, colour="LINE1"), width=0.1, size=.8) + 
  geom_line(aes(y=c,group=1,colour="LINE2"),size=1.0) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=3) +           #blue
  geom_errorbar(aes(ymin=f, ymax=g,colour="LINE2"), width=0.1, size=.8) + 
  scale_colour_manual(name="Error Bars",values=cols, 
                      guide = guide_legend(override.aes=aes(fill=NA))) + 
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

Replace double quotes with single ones:

INSERT
INTO    MY.LOGFILE
        (id,severity,category,logdate,appendername,message,extrainfo)
VALUES  (
       'dee205e29ec34',
       'FATAL',
       'facade.uploader.model',
       '2013-06-11 17:16:31',
       'LOGDB',
       NULL,
       NULL
       )

In SQL, double quotes are used to mark identifiers, not string constants.

If you cannot modify your php.ini configuration, you could as well use the following snippet at the beginning of your code:

date_default_timezone_set('Africa/Lagos');//or change to whatever timezone you want

The list of timezones can be found at http://www.php.net/manual/en/timezones.php.

use the variable, Oracle does not support SQL in that context without an INTO. With a properly named variable your code will be more legible anyway.

Run command rndc querylog on or add querylog yes; to options{}; section in named.conf to activate that channel.

Also make sure you’re checking correct directory if your bind is chrooted.

These are two different languages, that run at different time - you cannot interact with them like that.

PHP is executed on the server while the page loads. Once loaded, the JavaScript will execute on the clients machine in the browser.

You need make sure to start the session at the top of every PHP file where you want to use the $_SESSION superglobal. Like this:

<?php
  session_start();
  echo $_SESSION['youritem'];
?>

You forgot the Session HELPER.

Check this link : book.cakephp.org/2.0/en/core-libraries/helpers/session.html

To prevent this, make sure every BEGIN TRANSACTION has COMMIT

The following will say successful but will leave uncommitted transactions:

BEGIN TRANSACTION
BEGIN TRANSACTION
<SQL_CODE?
COMMIT

Closing query windows with uncommitted transactions will prompt you to commit your transactions. This will generally resolve the Error 1222 message.

There are a few misunderstandings in the discussion above.

First, you can always ROLLBACK a transaction... no matter what the state of the transaction. So you only have to check the XACT_STATE before a COMMIT, not before a rollback.

As far as the error in the code, you will want to put the transaction inside the TRY. Then in your CATCH, the first thing you should do is the following:

 IF @@TRANCOUNT > 0
      ROLLBACK TRANSACTION @transaction

Then, after the statement above, then you can send an email or whatever is needed. (FYI: If you send the email BEFORE the rollback, then you will definitely get the "cannot... write to log file" error.)

This issue was from last year, so I hope you have resolved this by now :-) Remus pointed you in the right direction.

As a rule of thumb... the TRY will immediately jump to the CATCH when there is an error. Then, when you're in the CATCH, you can use the XACT_STATE to decide whether you can commit. But if you always want to ROLLBACK in the catch, then you don't need to check the state at all.

error_reporting(E_ALL ^ E_WARNING);

:)

You should change subject to "How to fix warning from date() in PHP"...

you dont insert into identity fields. You need to specify the field names and use the Values clause

insert into #tmp (AssignedTo, field2, field3) values (value, value, value)

If you use do a insert into... select field field field it will insert the first field into that identity field and will bomb

It solved throung second parameter in Model load:

$this->load->model('user','User');

first parameter is the model's filename, and second it defining the name of model to be used in the controller:

function alluser() 
{
$this->load->model('User');
$result = $this->User->showusers();
}

By default login failed error message is nothing but a client user connection has been refused by the server due to mismatch of login credentials. First task you might check is to see whether that user has relevant privileges on that SQL Server instance and relevant database too, thats good. Obviously if the necessary prvileges are not been set then you need to fix that issue by granting relevant privileges for that user login.

Althought if that user has relevant grants on database & server if the Server encounters any credential issues for that login then it will prevent in granting the authentication back to SQL Server, the client will get the following error message:

Msg 18456, Level 14, State 1, Server <ServerName>, Line 1
Login failed for user '<Name>'

Ok now what, by looking at the error message you feel like this is non-descriptive to understand the Level & state. By default the Operating System error will show 'State' as 1 regardless of nature of the issues in authenticating the login. So to investigate further you need to look at relevant SQL Server instance error log too for more information on Severity & state of this error. You might look into a corresponding entry in log as:

2007-05-17 00:12:00.34 Logon     Error: 18456, Severity: 14, State: 8.
or

2007-05-17 00:12:00.34 Logon     Login failed for user '<user name>'.

As defined above the Severity & State columns on the error are key to find the accurate reflection for the source of the problem. On the above error number 8 for state indicates authentication failure due to password mismatch. Books online refers: By default, user-defined messages of severity lower than 19 are not sent to the Microsoft Windows application log when they occur. User-defined messages of severity lower than 19 therefore do not trigger SQL Server Agent alerts.

Sung Lee, Program Manager in SQL Server Protocols (Dev.team) has outlined further information on Error state description:The common error states and their descriptions are provided in the following table:

ERROR STATE       ERROR DESCRIPTION
------------------------------------------------------------------------------
2 and 5           Invalid userid
6                 Attempt to use a Windows login name with SQL Authentication
7                 Login disabled and password mismatch
8                 Password mismatch
9                 Invalid password
11 and 12         Valid login but server access failure
13                SQL Server service paused
18                Change password required


Well I'm not finished yet, what would you do in case of error:

2007-05-17 00:12:00.34 Logon     Login failed for user '<user name>'.

You can see there is no severity or state level defined from that SQL Server instance's error log. So the next troubleshooting option is to look at the Event Viewer's security log [edit because screen shot is missing but you get the

idea, look in the event log for interesting events].

You have to create a new template for item selection like this.

<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="ListBoxItem">
            <Border
                BorderThickness="{TemplateBinding Border.BorderThickness}"
                Padding="{TemplateBinding Control.Padding}"
                BorderBrush="{TemplateBinding Border.BorderBrush}"
                Background="{TemplateBinding Panel.Background}"
                SnapsToDevicePixels="True">
                <ContentPresenter
                    Content="{TemplateBinding ContentControl.Content}"
                    ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"
                    HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
                    VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
                    SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" />
            </Border>
        </ControlTemplate>
    </Setter.Value>
</Setter>

SQL Server was not configured to allow mixed authentication.

Here are steps to fix:

1. Right-click on SQL Server instance at root of Object Explorer, click on Properties
2. Select Security from the left pane.

3. Select the SQL Server and Windows Authentication mode radio button, and click OK.

   

4. Right-click on the SQL Server instance, select Restart (alternatively, open up Services and restart the SQL Server service).

This is also incredibly helpful for IBM Connections users, my wizards were not able to connect until I fxed this setting.

According to the CI docs (CodeIgniter Email Library)...

If you prefer not to set preferences using the above method, you can instead put them into a config file. Simply create a new file called the email.php, add the $config array in that file. Then save the file at config/email.php and it will be used automatically. You will NOT need to use the $this->email->initialize() function if you save your preferences in a config file.

I was able to get this to work by putting all the settings into application/config/email.php.

$config['useragent'] = 'CodeIgniter';
$config['protocol'] = 'smtp';
//$config['mailpath'] = '/usr/sbin/sendmail';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'YOURPASSWORDHERE';
$config['smtp_port'] = 465; 
$config['smtp_timeout'] = 5;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = FALSE;
$config['bcc_batch_size'] = 200;

Then, in one of the controller methods I have something like:

$this->load->library('email'); // Note: no $config param needed
$this->email->from('[email protected]', '[email protected]');
$this->email->to('[email protected]');
$this->email->subject('Test email from CI and Gmail');
$this->email->message('This is a test.');
$this->email->send();

Also, as Cerebro wrote, I had to uncomment out this line in my php.ini file and restart PHP:

extension=php_openssl.dll

The error means that you tried to enter a literal with a format string, but the length of the format string was not the same length as the literal.

One of these formats is incorrect:

TO_CHAR(t.alarm_datetime, 'YYYY-MM-DD HH24:MI:SS')
TO_DATE(alarm_datetime, 'DD.MM.YYYY HH24:MI:SS')

Just checked IE 7, Firefox 3.6.8 Mac, Firefox 3.6.8 Windows, and Safari:

word-wrap: break-word;

works for long links inside of a div with a set width and no overflow declared in the css:

#consumeralerts_leftcol{
    float:left;
    width: 250px;
    margin-bottom:10px;
    word-wrap: break-word;
}

I don't see any incompatibility issues

Your connection string is wrong

<connectionStrings>
   <add name="ConnStringDb1" connectionString="Data Source=localhost\SQLSERVER;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
</connectionStrings>

Here is a very good explanation of why using Laravel's Database Seeder is preferable to using Migrations: https://web.archive.org/web/20171018135835/http://laravelbook.com/laravel-database-seeding/

I did try multiple times without the conflict error - you do have to exit the app beforehand. Also, please note the parameters do differ slightly.

As often, numbers says more than feeling, here are some data: Pipe vs Unix Socket Performance (opendmx.net).

This benchmark shows a difference of about 12 to 15% faster speed for pipes.

Serialization is the process of converting an object's state to bits so that it can be stored on a hard drive. When you deserialize the same object, it will retain its state later. It lets you recreate objects without having to save the objects' properties by hand.

http://en.wikipedia.org/wiki/Serialization

You'll need to use an Iterator to loop through the keys to get their values.

Here's a Kotlin implementation, you will realised that the way I got the string is using optString(), which is expecting a String or a nullable value.

val keys = jsonObject.keys()
while (keys.hasNext()) {
    val key = keys.next()
    val value = targetJson.optString(key)        
}

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

Modifications to sys.path only apply for the life of that Python interpreter. If you want to do it permanently you need to modify the PYTHONPATH environment variable:

PYTHONPATH="/Me/Documents/mydir:$PYTHONPATH"
export PYTHONPATH

Note that PATH is the system path for executables, which is completely separate.

**You can write the above in ~/.bash_profile and the source it using source ~/.bash_profile

I had to run the Windows Command Prompt with Administrator privileges

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:

When location matches the last part of the directive’s value: it is better to use the root directive instead:

which would yield:

server {
  listen        8080;
  server_name   www.mysite.com mysite.com;
  error_log     /home/www-data/logs/nginx_www.error.log;
  error_page    404    /404.html;

  location /public/doc/ {
    autoindex on;
    root  /home/www-data/mysite;
  } 

  location = /404.html {
    root /home/www-data/mysite/static/html;
  }       
}

use JsonParser; for example:

JsonParser parser = new JsonParser();
JsonObject o = parser.parse("{\"a\": \"A\"}").getAsJsonObject();

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}

You could also solve it with an interface default method:

 @Query(select p from Person p where p.forename = :forename and p.surname = :surname)
User findByForenameAndSurname(@Param("surname") String lastname,
                         @Param("forename") String firstname);

default User findByName(Name name) {
  return findByForenameAndSurname(name.getLastname(), name.getFirstname());
}

Of course you'd still have the actual repository function publicly visible...

 SELECT id, GROUP_CONCAT(CONCAT_WS(':', Name, CAST(Value AS CHAR(7))) SEPARATOR ',') AS result 
    FROM test GROUP BY id

you must use cast or convert, otherwise will be return BLOB

result is

id         Column
1          A:4,A:5,B:8
2          C:9

you have to handle result once again by program such as python or java

In this case a relatively simple GROUP BY can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER():

Runnable example (Wofkflow20 error in original data corrected)

;WITH partitioned AS (
    SELECT company
        ,workflow
        ,date
        ,other_columns
        ,ROW_NUMBER() OVER(PARTITION BY company, workflow
                            ORDER BY date) AS seq
    FROM workflowTable
)
SELECT *
FROM partitioned WHERE seq = 1

similarly with awk

 awk '/^ABB\.log$/' file

I'm using Version 4.0.2.15 with Build 15.21

For me I needed this:

UPDATE table_name SET column_name = REPLACE(column_name,"search str","replace str");

Putting t.column_name in the first argument of replace did not work.

angular.module('app').directive('conversation', function() {
    return {
        restrict: 'E',
        link: function ($scope, $elm, $attr) {
            $scope.$watch("some_prop", function (newValue, oldValue) {
                  var typeId = $attr.type-id;
                  // Your logic.
            });
        }
    };
}

Can do this in jQuery. Try all options .height(), .innerHeight() or .outerHeight().

$('document').ready(function() {
    $('#right_div').css({'height': $('#left_div').innerHeight()});
});

Example Screenshot

Hope this helps. Thanks!!

I think you put the function in the $(document).ready....... The functions are always provided out the $(document).ready.......

It's not a matter of better, just different.

When you synchronize a method, you are effectively synchronizing to the object itself. In the case of a static method, you're synchronizing to the class of the object. So the following two pieces of code execute the same way:

public synchronized int getCount() {
    // ...
}

This is just like you wrote this.

public int getCount() {
    synchronized (this) {
        // ...
    }
}

If you want to control synchronization to a specific object, or you only want part of a method to be synchronized to the object, then specify a synchronized block. If you use the synchronized keyword on the method declaration, it will synchronize the whole method to the object or class.

Answer: From php 5.3 and >, the var keyword is equivalent to public when declaring variables inside a class.

class myClass {
  var $x;
}

is the same as (for php 5.3 and >):

class myClass {
  public $x;
}

History: It was previously the norm for declaring variables in classes, though later became depreciated, but later (PHP 5.3) it became un-depreciated.

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

1) It looks possible. This info on Github describes how to create a java program to send a message using the whatsapp encryption protocol from WhisperSystems.

2) No. See the whatsapp security white paper.

3) See #1.

<script type="text/javascript">
     function SelectAnimal(){
         //Set selected option of Animals based on AnimalToFind value...
         var animalTofind = document.getElementById('AnimalToFind');
         var selection = document.getElementById('Animals');

        // select element
        for(var i=0;i<selection.options.length;i++){
            if (selection.options[i].innerHTML == animalTofind.value) {
                selection.selectedIndex = i;
                break;
            }
        }
     }
</script>

setting the selectedIndex property of the select tag will choose the correct item. it is a good idea of instead of comparing the two values (options innerHTML && animal value) you can use the indexOf() method or regular expression to select the correct option despite casing or presense of spaces

selection.options[i].innerHTML.indexOf(animalTofind.value) != -1;

or using .match(/regular expression/)

Use this function:

$(".price").each(function(){
total_price += parseInt($(this).val());
});

If you need to mutate stuff, use ArrayBuffer or LinkedBuffer instead. However, it would be better to address this statement:

I need to declare empty list or empty maps and some where later in the code need to fill them.

Instead of doing that, fill the list with code that returns the elements. There are many ways of doing that, and I'll give some examples:

// Fill a list with the results of calls to a method
val l = List.fill(50)(scala.util.Random.nextInt)

// Fill a list with the results of calls to a method until you get something different
val l = Stream.continually(scala.util.Random.nextInt).takeWhile(x => x > 0).toList

// Fill a list based on its index
val l = List.tabulate(5)(x => x * 2)

// Fill a list of 10 elements based on computations made on the previous element
val l = List.iterate(1, 10)(x => x * 2)

// Fill a list based on computations made on previous element, until you get something
val l = Stream.iterate(0)(x => x * 2 + 1).takeWhile(x => x < 1000).toList

// Fill list based on input from a file
val l = (for (line <- scala.io.Source.fromFile("filename.txt").getLines) yield line.length).toList

As stated in one of the comments, this works for Mac (probably for Windows/Linux too):

I WANT TO CONNECT FROM A CONTAINER TO A SERVICE ON THE HOST

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS name host.docker.internal which resolves to the internal IP address used by the host. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

You can also reach the gateway using gateway.docker.internal.

Quoted from https://docs.docker.com/docker-for-mac/networking/

This worked for me without using --net=host.

In most situations, git fetch should do what you want, which is 'get anything new from the remote repository and put it in your local copy without merging to your local branches'. git fetch --tags does exactly that, except that it doesn't get anything except new tags.

In that sense, git fetch --tags is in no way a superset of git fetch. It is in fact exactly the opposite.

git pull, of course, is nothing but a wrapper for a git fetch <thisrefspec>; git merge. It's recommended that you get used to doing manual git fetching and git mergeing before you make the jump to git pull simply because it helps you understand what git pull is doing in the first place.

That being said, the relationship is exactly the same as with git fetch. git pull is the superset of git pull --tags.

You can try this:

<div ng-app="app">
    <div ng-controller="AppCtrl">
        <a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
    </div>
</div>

<script>
var app = angular.module('app', []);

function AppCtrl($scope) {
        $scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
        $scope.fxn = function () {
            alert('It works');
        };
    }

app.directive("myDir", function ($compile) {
    return {
        scope: {ngClick: '='}
    };
});
</script>

I'm not sure if our problem was directly related with installing gulp only locally. But we had to install a bunch of dependencies ourself. This lead to a "huge" package.json and we are not sure if it is really a great idea to install gulp only locally. We had to do so because of our build environment. But I wouldn't recommend installing gulp not globally if it isn't absolutely necessary. We faced similar problems as described in the following blog-post

None of these problems arise for any of our developers on their local machines because they all installed gulp globally. On the build system we had the described problems. If someone is interested I could dive deeper into this issue. But right now I just wanted to mention that it isn't an easy path to install gulp only locally.

Depending on your platform you can use: sqlite3 file_name.db from the terminal. .tables will list the tables, .schema is full layout. SQLite commands like: select * from table_name; and such will print out the full contents. Type: ".exit" to exit. No need to download a GUI application.Use a semi-colon if you want it to execute a single command. Decent SQLite usage tutorial http://www.thegeekstuff.com/2012/09/sqlite-command-examples/

 public static string ConvertToCaptilize(string input)
        {
            if (!string.IsNullOrEmpty(input))
            {
                string[] arrUserInput = input.Split(' ');


                // Initialize a string builder object for the output
                StringBuilder sbOutPut = new StringBuilder();


                // Loop thru each character in the string array
                foreach (string str in arrUserInput)
                {
                    if (!string.IsNullOrEmpty(str))
                    {
                        var charArray = str.ToCharArray();
                        int k = 0;
                        foreach (var cr in charArray)
                        {
                            char c;
                            c = k == 0 ? char.ToUpper(cr) : char.ToLower(cr);
                            sbOutPut.Append(c);
                            k++;
                        }


                    }
                    sbOutPut.Append(" ");
                }
                return sbOutPut.ToString();
            }
            return string.Empty;

        }

One simple way to get rid of the overwriting issue is to use File.AppendText to append line at the end of the file as

void Main()
{
    using (System.IO.StreamWriter sw = System.IO.File.AppendText("file.txt"))
    {          
        string first = reader[0].ToString();
        string second=image.ToString();
        string csv = string.Format("{0},{1}\n", first, second);
        sw.WriteLine(csv);
    }
} 

Code supporting arbitrary byte orders, ready to be put into a file called order32.h:

#ifndef ORDER32_H
#define ORDER32_H

#include <limits.h>
#include <stdint.h>

#if CHAR_BIT != 8
#error "unsupported char size"
#endif

enum
{
    O32_LITTLE_ENDIAN = 0x03020100ul,
    O32_BIG_ENDIAN = 0x00010203ul,
    O32_PDP_ENDIAN = 0x01000302ul,      /* DEC PDP-11 (aka ENDIAN_LITTLE_WORD) */
    O32_HONEYWELL_ENDIAN = 0x02030001ul /* Honeywell 316 (aka ENDIAN_BIG_WORD) */
};

static const union { unsigned char bytes[4]; uint32_t value; } o32_host_order =
    { { 0, 1, 2, 3 } };

#define O32_HOST_ORDER (o32_host_order.value)

#endif

You would check for little endian systems via

O32_HOST_ORDER == O32_LITTLE_ENDIAN

In layman's terms:

• JDBC is a standard for Database Access
• JPA is a standard for ORM

JDBC is a standard for connecting to a DB directly and running SQL against it - e.g SELECT * FROM USERS, etc. Data sets can be returned which you can handle in your app, and you can do all the usual things like INSERT, DELETE, run stored procedures, etc. It is one of the underlying technologies behind most Java database access (including JPA providers).

One of the issues with traditional JDBC apps is that you can often have some crappy code where lots of mapping between data sets and objects occur, logic is mixed in with SQL, etc.

JPA is a standard for Object Relational Mapping. This is a technology which allows you to map between objects in code and database tables. This can "hide" the SQL from the developer so that all they deal with are Java classes, and the provider allows you to save them and load them magically. Mostly, XML mapping files or annotations on getters and setters can be used to tell the JPA provider which fields on your object map to which fields in the DB. The most famous JPA provider is Hibernate, so it's a good place to start for concrete examples.

Other examples include OpenJPA, toplink, etc.

Under the hood, Hibernate and most other providers for JPA write SQL and use JDBC to read and write from and to the DB.

that depends on what kind of information are you passing to the conditional..

sometimes your result will be null or undefined or '' or 0, for my simple validation i use this if.

( $('#id').val() == '0' || $('#id').val() == '' || $('#id').val() == 'undefined' || $('#id').val() == null )

NOTE: null != 'null'

When using Server validator controls you have to be careful about fact that any one can disable javascript in their browser. So you should use Page.IsValid Property always at server side.

Ólafur forgot the surrogate key:

A surrogate key in a database is a unique identifier for either an entity in the modeled world or an object in the database. The surrogate key is not derived from application data.

It is a old question but i ran across the same issues. If you wanna see live output you can run

forever logs

This would show the path of the logs file as well as the number of the script. You can then use

forever logs 0 -f

0 should be replaced by the number of the script you wanna see the output for.

UPDATE table1
SET 
`ID` = (SELECT table2.id FROM table2 WHERE table1.`name`=table2.`name`)

An example of an IF Statement that can be used to add a calculation into the cell you wish to hide if value = 0 but displayed upon another cell value reference.

=IF(/Your reference cell/=0,"",SUM(/Here you put your SUM/))

You could use PHP's array_reduce as well,

$a = ['Name' => 'Last Name'];

function acc($acc,$k)use($a){ return $acc .= $k.":".$a[$k].",";}

$imploded = array_reduce(array_keys($a), "acc");

As an alternative to WMI you can get fast accurate results by tapping in to WinSpool.drv (i.e. Windows API) - you can get all the details on the interfaces, structs & constants from pinvoke.net, or I've put the code together at http://delradiesdev.blogspot.com/2012/02/accessing-printer-status-using-winspool.html

nib is fine. If in doubt, refer to the Python style guide.

From PEP 8:

Package and Module Names Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

Since module names are mapped to file names, and some file systems are case insensitive and truncate long names, it is important that module names be chosen to be fairly short -- this won't be a problem on Unix, but it may be a problem when the code is transported to older Mac or Windows versions, or DOS.

When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket).

depends on the isolation level of the incomming transaction.

Sql transaction isolation explained

It doesn't make any sense to have a named overloaded constructor in an anonymous class, as there would be no way to call it, anyway.

Depending on what you are actually trying to do, just accessing a final local variable declared outside the class, or using an instance initializer as shown by Arne, might be the best solution.

in my case, I was passing all the parameters but one of the parameter my code was passing a null value for string.

Eg: cmd.Parameters.AddWithValue("@userName", userName);

in the above case, if the data type of userName is string, I was passing userName as null.

In the interface, you specify the property:

public interface IResourcePolicy
{
   string Version { get; set; }
}

In the implementing class, you need to implement it:

public class ResourcePolicy : IResourcePolicy
{
   public string Version { get; set; }
}

This looks similar, but it is something completely different. In the interface, there is no code. You just specify that there is a property with a getter and a setter, whatever they will do.

In the class, you actually implement them. The shortest way to do this is using this { get; set; } syntax. The compiler will create a field and generate the getter and setter implementation for it.

The above answers are correct but I calling spyder within my virtualenv would still use my PATH to look up the version of spyder in my default anaconda env. I found this answer which gave the following workaround:

source activate my_env            # activate your target env with spyder installed
conda info -e                     # look up the directory of your conda env
find /path/to/my/env -name spyder # search for the spyder executable in your env
/path/to/my/env/then/to/spyder    # run that executable directly

I chose this over modifying PATH or adding a link to the executable at a higher priority in PATH since I felt this was less likely to break other programs. However, I did add an alias to the executable in ~/.bash_aliases.

You might also have a use case where you want to delete a block of text and replace it.

Like this

Hello World

Hello World

To

Hello Cool

Hello Cool

You can just visual block select "World" in both lines.

Type c for change - now you will be in insert mode.

Insert the stuff you want and hit escape.

Both get reflected vertically. It works just like 'I', except that it replaces the block with the new text instead of inserting it.

While these answers are technically correct, including Ushox, I think the approved way is to implement a new protocol or re-use an existing one. A protocol insulates the observer from the observed, sort of like putting a mail slot in between them. In effect, that is what Gabriel does via the pushViewController method invocation; the view "knows" that it is proper protocol to politely ask your navigationController to push a view, since the viewController conforms to the navigationController protocol. While you can create your own protocol, just using Gabriel's example and re-using the UINavigationController protocol is just fine.

SQl Management Studio data import looks at the first few rows to determine source data specs..

shift your records around so that the longest text is at top.

I also ran into the same problem, where the initial dtabase size is set to 4Gb and autogrowth is set by 1Mb. The virtual encrypted TrueCrypt drive that the databse was on, seemed to have plenty of space.

I changed a couple of (the above) things:

• I turned the Windows service for Sql Server Express from automatic to manual, so only the 'regular' Sql Server is running. (Even though I am running Sql Server 2008 R2 which should allow 10 GB.)
• I changed the autogrowth from 1 MB to 10%
• I changed the autogrowth increment-size from 10% to 1000 MB
• I defragmented the drive
• I shrank the database:
  • manually DBCC SHRINKDATABASE('...')
  • automatically right click on database | "properties" | "Auto Shrink" | "Truncate log on check point")

All to little avail (I could insert some more records, but soon ran into the same problem). The pagefile mentioned by Tobbi, made me try a larger virtual drive. (Even though my drive should not contain any such system files, since I run without it being mounted a lot of the time.)

• I made a new larger virtual drive with TrueCrypt

When making this, I ran into a TrueCrypt-question, if I am going to store files larger than 4gb (as shown in this SuperUser question).

• I told TrueCrypt I would store files larger than 4 GB

After these last two I was doing fine, and I am assuming this last one did the trick. I think TrueCrypt chooses an exfat file system (as described here), which limits all files to 4GB. (So I probably did not need to enlarge the drive after all, but I did anyway.)

This is probably a very rare border case, but maybe it is of help to somebody.

The HTML4 spec for the <input> element specifies the following script events are available:

onfocus, onblur, onselect, onchange, onclick, ondblclick, onmousedown, onmouseup, onmouseover, onmousemove, onmouseout, onkeypress, onkeydown, onkeyup

here's an example that bind's to all these events and shows what's going on http://jsfiddle.net/pxfunc/zJ7Lf/

I think you can filter out which events are truly relevent to your situation and detect what the text value was before and after the event to determine a change

jqyery this is another version with jquery a little less shorter. assuming that the <a> element is inside de <li> element

$(li).click(function(){

In case of plotting time series, the command ts.plot requires a different argument than xaxt="n"

require(graphics)
ts.plot(ldeaths, mdeaths, xlab="year", ylab="deaths", lty=c(1:2), gpars=list(xaxt="n"))
axis(1, at = seq(1974, 1980, by = 2))

In my case it failed to fetch be.archives.ubuntu.com (Belgium) so I generated a new sources.plist on this link as recommended by the accepted answer.

The thing that solved it for me was just to change the country to United States when generating the sources.plist. Then I could run this again.

apt-get update

The following code will work:

ComboBox1.SelectedIndex.Equals(String.Empty);

You should put this line in your application context:

<context:component-scan base-package="com.cinebot.service" />

I took a look at this and I found that a WebView doesn't seem to send click events to an OnClickListener. If anyone out there can prove me wrong or tell me why then I'd be interested to hear it.

What I did find is that a WebView will send touch events to an OnTouchListener. It does have its own onTouchEvent method but I only ever seemed to get MotionEvent.ACTION_MOVE using that method.

So given that we can get events on a registered touch event listener, the only problem that remains is how to circumvent whatever action you want to perform for a touch when the user clicks a URL.

This can be achieved with some fancy Handler footwork by sending a delayed message for the touch and then removing those touch messages if the touch was caused by the user clicking a URL.

Here's an example:

public class WebViewClicker extends Activity implements OnTouchListener, Handler.Callback {

private static final int CLICK_ON_WEBVIEW = 1;
private static final int CLICK_ON_URL = 2;

private final Handler handler = new Handler(this);

private WebView webView;
private WebViewClient client;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.web_view_clicker);

    webView = (WebView)findViewById(R.id.web);
    webView.setOnTouchListener(this);

    client = new WebViewClient(){ 
        @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { 
            handler.sendEmptyMessage(CLICK_ON_URL);
            return false;
        } 
    }; 

    webView.setWebViewClient(client);
    webView.setVerticalScrollBarEnabled(false);
    webView.loadUrl("http://www.example.com");
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if (v.getId() == R.id.web && event.getAction() == MotionEvent.ACTION_DOWN){
        handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 500);
    }
    return false;
}

@Override

Hope this helps.

In my example, two timeouts are set. The connection timeout throws java.net.SocketTimeoutException: Socket is not connected and the socket timeout java.net.SocketTimeoutException: The operation timed out.

HttpGet httpGet = new HttpGet(url);
HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is established.
// The default value is zero, that means the timeout is not used. 
int timeoutConnection = 3000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT) 
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 5000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
HttpResponse response = httpClient.execute(httpGet);

If you want to set the Parameters of any existing HTTPClient (e.g. DefaultHttpClient or AndroidHttpClient) you can use the function setParams().

httpClient.setParams(httpParameters);

If your include directories are referenced correctly in the VC++ project property sheet -> Configuration Properties -> VC++ directories->Include directories.The path is referenced in the macro $(VC_IncludePath) In my VS 2015 this evaluates to : "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include"

using namespace std;
#include <iostream> 

That did it for me.

These are the vendor-prefixed properties offered by the relevant rendering engines (-webkit for Chrome, Safari; -moz for Firefox, -o for Opera, -ms for Internet Explorer). Typically they're used to implement new, or proprietary CSS features, prior to final clarification/definition by the W3.

This allows properties to be set specific to each individual browser/rendering engine in order for inconsistencies between implementations to be safely accounted for. The prefixes will, over time, be removed (at least in theory) as the unprefixed, the final version, of the property is implemented in that browser.

To that end it's usually considered good practice to specify the vendor-prefixed version first and then the non-prefixed version, in order that the non-prefixed property will override the vendor-prefixed property-settings once it's implemented; for example:

.elementClass {
    -moz-border-radius: 2em;
    -ms-border-radius: 2em;
    -o-border-radius: 2em;
    -webkit-border-radius: 2em;
    border-radius: 2em;
}

Specifically, to address the CSS in your question, the lines you quote:

-webkit-column-count: 3;
-webkit-column-gap: 10px;
-webkit-column-fill: auto;
-moz-column-count: 3;
-moz-column-gap: 10px;
-moz-column-fill: auto;

Specify the column-count, column-gap and column-fill properties for Webkit browsers and Firefox.

I followed the steps in killthrush's answer and to my surprise it did not work. Logging in as sa I could see my Windows domain user and had made them a sysadmin, but when I tried logging in with Windows auth I couldn't see my login under logins, couldn't create databases, etc. Then it hit me. That login was probably tied to another domain account with the same name (with some sort of internal/hidden ID that wasn't right). I had left this organization a while back and then came back months later. Instead of re-activating my old account (which they might have deleted) they created a new account with the same domain\username and a new internal ID. Using sa I deleted my old login, re-added it with the same name and added sysadmin. I logged back in with Windows Auth and everything looks as it should. I can now see my logins (and others) and can do whatever I need to do as a sysadmin using my Windows auth login.

You can open a command prompt (Start -> Run -> cmd, use the cd command to change directories) and call your program from there, or add a getchar() call at the end of the program, which will wait until you press Enter. In Windows, you can also use system("pause"), which will display a "Press enter to continue..." (or something like that) message.

Remove any old versions of Django

If you are upgrading your installation of Django from a previous version, you will need to uninstall the old Django version before installing the new version.

If you installed Django using pip or easy_install previously, installing with pip or easy_install again will automatically take care of the old version, so you don’t need to do it yourself.

If you previously installed Django using python setup.py install, uninstalling is as simple as deleting the django directory from your Python site-packages. To find the directory you need to remove, you can run the following at your shell prompt (not the interactive Python prompt):

$ python -c "import django; print(django.path)"

Note: All of the following instructions apply universally (aka to all OSes) unless otherwise specified.

Prerequsites

You will need:

• A working Java installation
• A working terminal/command prompt
• A computer
• An APK file

Steps

Step 1: Changing the file extension of the APK file

1. Change the file extension of the .apk file by either adding a .zip extension to the filename, or to change .apk to .zip.

   For example, com.example.apk becomes com.example.zip, or com.example.apk.zip. Note that on Windows and macOS, it may prompt you whether you are sure you want to change the file extension. Click OK or Add if you're using macOS:

Step 2: Extracting Java files from APK

1. Extract the renamed APK file in a specific folder. For example, let that folder be demofolder.

   • If it didn't work, try opening the file in another application such as WinZip or 7-Zip.

   • For macOS, you can try running unzip in Terminal (available at /Applications/Terminal.app), where it takes one or more arguments: the file to unzip + optional arguments. See man unzip for documentation and arguments.

2. Download dex2jar (see all releases on GitHub) and extract that zip file in the same folder as stated in the previous point.

3. Open command prompt (or a terminal) and change your current directory to the folder created in the previous point and type the command d2j-dex2jar.bat classes.dex and press enter. This will generate classes-dex2jar.jar file in the same folder.

   • macOS/Linux users: Replace d2j-dex2jar.bat with d2j-dex2jar.sh. In other words, run d2j-jar2dex.sh classes.dex in the terminal and press enter.

4. Download Java Decompiler (see all releases on Github) and extract it and start (aka double click) the executable/application.

5. From the JD-GUI window, either drag and drop the generated classes-dex2jar.jar file into it, or go to File > Open File... and browse for the jar.

6. Next, in the menu, go to File > Save All Sources (Windows: Ctrl+Alt+S, macOS: ?+?+S). This should open a dialog asking you where to save a zip file named `classes-dex2jar.jar.src.zip" consisting of all packages and java files. (You can rename the zip file to be saved)

7. Extract that zip file (classes-dex2jar.jar.src.zip) and you should get all java files of the application.

Step 3: Getting xml files from APK

• For more info, see the apktool website for installation instructions and more

• Windows:

  1. Download the wrapper script (optional) and the apktool jar (required) and place it in the same folder (for example, myxmlfolder).
  2. Change your current directory to the myxmlfolder folder and rename the apktool jar file to apktool.jar.
  3. Place the .apk file in the same folder (i.e myxmlfolder).

  4. Open the command prompt (or terminal) and change your current directory to the folder where apktool is stored (in this case, myxmlfolder). Next, type the command apktool if framework-res.apk.

     What we're doing here is that we are installing a framework. For more info, see the docs.

  5. The above command should result in "Framework installed ..."

  6. In the command prompt, type the command apktool d filename.apk (where filename is the name of apk file). This should decode the file. For more info, see the docs.

     This should result in a folder filename.out being outputted, where filename is the original name of the apk file without the .apk file extension. In this folder are all the XML files such as layout, drawables etc.

I prefer this method as it doesn't require manually emitting markup. I use this because I'm rendering Razor Pages to strings and sending them out via email, which is an environment where the white-space styling won't always work.

public static IHtmlContent RenderNewlines<TModel>(this IHtmlHelper<TModel> html, string content)
{
    if (string.IsNullOrEmpty(content) || html is null)
    {
        return null;
    }

    TagBuilder brTag = new TagBuilder("br");
    IHtmlContent br = brTag.RenderSelfClosingTag();
    HtmlContentBuilder htmlContent = new HtmlContentBuilder();

    // JAS: On the off chance a browser is using LF instead of CRLF we strip out CR before splitting on LF.
    string lfContent = content.Replace("\r", string.Empty, StringComparison.InvariantCulture);
    string[] lines = lfContent.Split('\n', StringSplitOptions.None);
    foreach(string line in lines)
    {
        _ = htmlContent.Append(line);
        _ = htmlContent.AppendHtml(br);
    }

    return htmlContent;
}

please use this code for input text

$('#search').on("input",function (e) {});

if you use .on("change",function (e) {}); then you need to blur input

if you use .on("keyup",function (e) {}); then you get value before the last character you typed

Answers that suggest that the header provided in the question are supported out of the box by WCF are incorrect. The header in the question contains a Nonce and a Created timestamp in the UsernameToken, which is an official part of the WS-Security specification that WCF does not support. WCF only supports username and password out of the box.

If all you need to do is add a username and password, then Sergey's answer is the least-effort approach. If you need to add any other fields, you will need to supply custom classes to support them.

A somewhat more elegant approach that I found was to override the ClientCredentials, ClientCredentialsSecurityTokenManager and WSSecurityTokenizer classes to support the additional properties. I've provided a link to the blog post where the approach is discussed in detail, but here is the sample code for the overrides:

public class CustomCredentials : ClientCredentials
{
    public CustomCredentials()
    { }

    protected CustomCredentials(CustomCredentials cc)
        : base(cc)
    { }

    public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager()
    {
        return new CustomSecurityTokenManager(this);
    }

    protected override ClientCredentials CloneCore()
    {
        return new CustomCredentials(this);
    }
}

public class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager
{
    public CustomSecurityTokenManager(CustomCredentials cred)
        : base(cred)
    { }

    public override System.IdentityModel.Selectors.SecurityTokenSerializer CreateSecurityTokenSerializer(System.IdentityModel.Selectors.SecurityTokenVersion version)
    {
        return new CustomTokenSerializer(System.ServiceModel.Security.SecurityVersion.WSSecurity11);
    }
}

public class CustomTokenSerializer : WSSecurityTokenSerializer
{
    public CustomTokenSerializer(SecurityVersion sv)
        : base(sv)
    { }

    protected override void WriteTokenCore(System.Xml.XmlWriter writer,
                                            System.IdentityModel.Tokens.SecurityToken token)
    {
        UserNameSecurityToken userToken = token as UserNameSecurityToken;

        string tokennamespace = "o";

        DateTime created = DateTime.Now;
        string createdStr = created.ToString("yyyy-MM-ddTHH:mm:ss.fffZ");

        // unique Nonce value - encode with SHA-1 for 'randomness'
        // in theory the nonce could just be the GUID by itself
        string phrase = Guid.NewGuid().ToString();
        var nonce = GetSHA1String(phrase);

        // in this case password is plain text
        // for digest mode password needs to be encoded as:
        // PasswordAsDigest = Base64(SHA-1(Nonce + Created + Password))
        // and profile needs to change to
        //string password = GetSHA1String(nonce + createdStr + userToken.Password);

        string password = userToken.Password;

        writer.WriteRaw(string.Format(
        "<{0}:UsernameToken u:Id=\"" + token.Id +
        "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" +
        "<{0}:Username>" + userToken.UserName + "</{0}:Username>" +
        "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" +
        password + "</{0}:Password>" +
        "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" +
        nonce + "</{0}:Nonce>" +
        "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace));
    }

    protected string GetSHA1String(string phrase)
    {
        SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider();
        byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase));
        return Convert.ToBase64String(hashedDataBytes);
    }

}

Before creating the client, you create the custom binding and manually add the security, encoding and transport elements to it. Then, replace the default ClientCredentials with your custom implementation and set the username and password as you would normally:

var security = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement();
    security.IncludeTimestamp = false;
    security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256;
    security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;

var encoding = new TextMessageEncodingBindingElement();
encoding.MessageVersion = MessageVersion.Soap11;

var transport = new HttpsTransportBindingElement();
transport.MaxReceivedMessageSize = 20000000; // 20 megs

binding.Elements.Add(security);
binding.Elements.Add(encoding);
binding.Elements.Add(transport);

RealTimeOnlineClient client = new RealTimeOnlineClient(binding,
    new EndpointAddress(url));

    client.ChannelFactory.Endpoint.EndpointBehaviors.Remove(client.ClientCredentials);
client.ChannelFactory.Endpoint.EndpointBehaviors.Add(new CustomCredentials());

client.ClientCredentials.UserName.UserName = username;
client.ClientCredentials.UserName.Password = password;

$rootScope basically functions as an event listener and dispatcher.

To answer the question of how it is used, it used in conjunction with rootScope.$on;

$rootScope.$broadcast("hi");

$rootScope.$on("hi", function(){
    //do something
});

However, it is a bad practice to use $rootScope as your own app's general event service, since you will quickly end up in a situation where every app depends on $rootScope, and you do not know what components are listening to what events.

The best practice is to create a service for each custom event you want to listen to or broadcast.

.service("hiEventService",function($rootScope) {
    this.broadcast = function() {$rootScope.$broadcast("hi")}
    this.listen = function(callback) {$rootScope.$on("hi",callback)}
})

MySQL doesn't support multi-table insertion in a single INSERT statement. Oracle is the only one I'm aware of that does, oddly...

INSERT INTO NAMES VALUES(...)
INSERT INTO PHONES VALUES(...)

string connString = "<your connection string>";
string sql = "name of your sp";

using(SqlConnection conn = new SqlConnection(connString)) 
{
    try 
    {
        using(SqlDataAdapter da = new SqlDataAdapter()) 
        {
            da.SelectCommand = new SqlCommand(sql, conn);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;

            DataSet ds = new DataSet();   
            da.Fill(ds, "result_name");

            DataTable dt = ds.Tables["result_name"];

            foreach (DataRow row in dt.Rows) {
                //manipulate your data
            }
        }    
    } 
    catch(SQLException ex) 
    {
        Console.WriteLine("SQL Error: " + ex.Message);
    }
    catch(Exception e) 
    {
        Console.WriteLine("Error: " + e.Message);
    }
}

As a contemporary answer, if running Windows 10 you can use the "Linux Subsystem for Windows".

https://docs.microsoft.com/en-us/windows/wsl/install-win10

This will allow you to run native linux commands from within windows and thus run tail exactly how you would in linux.

Use %03d in the format specifier for the integer. The 0 means that the number will be zero-filled if it is less than three (in this case) digits.

See the Formatter docs for other modifiers.

The value of a sticky broadcast is the value that was last broadcast and is currently held in the sticky cache. This is not the value of a broadcast that was received right now. I suppose you can say it is like a browser cookie that you can access at any time. The sticky broadcast is now deprecated, per the docs for sticky broadcast methods (e.g.):

This method was deprecated in API level 21. Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that something has changed, with another mechanism for apps to retrieve the current value whenever desired.

If you don't want to install the cors library and instead want to fix your original code, the other step you are missing is that Access-Control-Allow-Origin:* is wrong. When passing Authentication tokens (e.g. JWT) then you must explicitly state every url that is calling your server. You can't use "*" when doing authentication tokens.

Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point

We can use ng-src but when ng-src's value became null, '' or undefined, ng-src will not work. So just use ng-if for this case:

http://jsfiddle.net/Hx7B9/299/

<div ng-app>
    <div ng-controller="AppCtrl"> 
        <a href='#'><img ng-src="{{link}}" ng-if="!!link"/></a>
        <button ng-click="changeLink()">Change Image</button>
    </div>
</div>

<html>
  <head>
    <script type="text/javascript" src="jquery.js"></script>
    <script>
      $(document).ready(function(){
        var locations = ["http://webPage1.com", "http://webPage2.com"];
        var len = locations.length;
        var iframe = $('#frame');
        var i = 0;
        setInterval(function () {
            iframe.attr('src', locations[++i % len]);
        }, 30000);
      });
    </script>
  </head>
  <body>
    <iframe id="frame"></iframe>
  </body>
</html>

Now you need to implement like this

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { //>= API 21
        //
    } else {
        //
    }

Following single line of code is enough, everything will take care by ContextCompat.getDrawable

ContextCompat.getDrawable(this, R.drawable.your_drawable_file)

If you need to return a JSON object using a String, then the following should work:

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.http.ResponseEntity;
...

@RestController
@RequestMapping("/student")
public class StudentController {

    @GetMapping
    @RequestMapping("/")
    public ResponseEntity<JsonNode> get() throws JsonProcessingException {
        ObjectMapper mapper = new ObjectMapper();
        JsonNode json = mapper.readTree("{\"id\": \"132\", \"name\": \"Alice\"}");
        return ResponseEntity.ok(json);
    }
    ...
}

For simple UTF-8 encoding, with slightly better compatibility than TextEncoder, Blob does the trick. Won't work in very old browsers though.

new Blob([""]).size; // -> 4  

I think you've missed the point of access control.

A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.

Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.

In your specific case, it seems that paste.ee doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).

Option 1 and 2 involves using inner class that will make the code kind of clutter. Option 2 is sort of messy because there will be one listener for every button. If you have small number of button, this is okay. For option 4 I think this will be harder to debug as you will have to go back and fourth the xml and java code. I personally use option 3 when I have to handle multiple button clicks.

The DBCC CHECKIDENT management command is used to reset identity counter. The command syntax is:

DBCC CHECKIDENT (table_name [, { NORESEED | { RESEED [, new_reseed_value ]}}])
[ WITH NO_INFOMSGS ]

Example:

DBCC CHECKIDENT ('[TestTable]', RESEED, 0);
GO

It was not supported in previous versions of the Azure SQL Database but is supported now.

Thanks to Solomon Rutzky the docs for the command are now fixed.

In your iOS App can't find a Numeric Keypad attached to your OS X. So you just need to Uncheck connect Hardware Keyboard option in your Simulator, in the following path just for testing purpose:

Simulator -> Hardware -> Keyboard -> Connect Hardware Keyboard

This will resolve the above issue.

I think you should see the below link too. It says it's a bug in the XCode at the end of that Forum post thread!

Reference

You can just specify the generic octet-stream MIME type:

public FileResult Download()
{
    byte[] fileBytes = System.IO.File.ReadAllBytes(@"c:\folder\myfile.ext");
    string fileName = "myfile.ext";
    return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
}

You can use the one below. I tested this with leading zero bytes and with initial negative bytes as well

public static String toHex(byte[] bytes) {
    BigInteger bi = new BigInteger(1, bytes);
    return String.format("%0" + (bytes.length << 1) + "X", bi);
}

If you want lowercase hex digits, use "x" in the format String.

<div class="row" *ngIf="teamMembers?.length > 0">

This checks first if teamMembers has a value and if teamMembers doesn't have a value, it doesn't try to access length of undefined because the first part of the condition already fails.

You can get from the same api without any additional api or url call.

HTML

<input class="wd100" id="fromInput" type="text" name="grFrom" placeholder="From" required/>

Javascript

var input = document.getElementById('fromInput');
var defaultBounds = new google.maps.LatLngBounds(
    new google.maps.LatLng(-33.8902, 151.1759),
    new google.maps.LatLng(-33.8474, 1512631)
)

var options = {
bounds: defaultBounds   
}

var autocomplete = new google.maps.places.Autocomplete(input, options);
var searchBox = new google.maps.places.SearchBox(input, {
         bounds: defaultBounds
});


google.maps.event.addListener(searchBox, 'places_changed', function() {
    var places = searchBox.getPlaces();


console.log(places[0].geometry.location.G); // Get Latitude
console.log(places[0].geometry.location.K); // Get Longitude

//Additional information
console.log(places[0].formatted_address); // Formated Address of Place
console.log(places[0].name); // Name of Place






    if (places.length == 0) {
      return;
    }

    var bounds = new google.maps.LatLngBounds();
    console.log(bounds);
     });
   }

You can use group by instead of distinct. Because when you use distinct, you'll get struggle to select all values from table. Unlike when you use group by, you can get distinct values and also all fields in table.

I often do this:

arr = ["a", "b", "c"]

(0...arr.length).map do |int|
  [arr[int], int + 2]
end

#=> [["a", 2], ["b", 3], ["c", 4]]

Instead of directly iterating over the elements of the array, you're iterating over a range of integers and using them as the indices to retrieve the elements of the array.

Database default values are not "portably" supported. The only way to use database default values is through the columnDefinition mapping attribute where you specify the SQL snippet (DEFAULT cause inclusive) for the column the field is mapped to.

You can use:

<?php
/**
 * @Entity
 */
class myEntity {
    /**
     * @var string
     *
     * @Column(name="myColumn", type="string", length="50")
     */
    private $myColumn = 'myDefaultValue';
    ...
}

PHP-level default values are preferred as these are also properly available on newly created and persisted objects (Doctrine will not go back to the database after persisting a new object to get the default values).

Simply use the macros from <float.h> and the variable-width conversion specifier (".*"):

float f = 3.14159265358979323846;
printf("%.*f\n", FLT_DIG, f);

Try

.text() or .html() instead of .innerHTML

As of Laravel v7.X, the framework now comes with a minimal API wrapped around the Guzzle HTTP client. It provides an easy way to make get, post, put, patch, and delete requests using the HTTP Client:

use Illuminate\Support\Facades\Http;

$response = Http::get('http://test.com');
$response = Http::post('http://test.com');
$response = Http::put('http://test.com');
$response = Http::patch('http://test.com');
$response = Http::delete('http://test.com');

You can manage responses using the set of methods provided by the Illuminate\Http\Client\Response instance returned.

$response->body() : string;
$response->json() : array;
$response->status() : int;
$response->ok() : bool;
$response->successful() : bool;
$response->serverError() : bool;
$response->clientError() : bool;
$response->header($header) : string;
$response->headers() : array;

Please note that you will, of course, need to install Guzzle like so:

composer require guzzlehttp/guzzle

There are a lot more helpful features built-in and you can find out more about these set of the feature here: https://laravel.com/docs/7.x/http-client

This is definitely now the easiest way to make external API calls within Laravel.

The localStorage can only store string content and you are trying to store a jQuery object since html(htmlString) returns a jQuery object.

You need to set the string content instead of an object. And use the setItem method to add data and getItem to get data.

window.localStorage.setItem('content', 'Test');
$('#test').html(window.localStorage.getItem('content'));

Simple version for Python 2.7+

my_ordered_dict = json.loads(json_str, object_pairs_hook=collections.OrderedDict)

Or for Python 2.4 to 2.6

import simplejson as json
import ordereddict

my_ordered_dict = json.loads(json_str, object_pairs_hook=ordereddict.OrderedDict)

You can use:

dir /s

If you need the list without all the header/footer information try this:

dir /s /b

(For sure this will work for DOS 6 and later; might have worked prior to that, but I can't recall.)

The problem in your code is that you want to apply the operation on every row. The way you've written it though takes the whole 'bar' and 'foo' columns, converts them to strings and gives you back one big string. You can write it like:

df.apply(lambda x:'%s is %s' % (x['bar'],x['foo']),axis=1)

It's longer than the other answer but is more generic (can be used with values that are not strings).

(Just assumption, less info of Exception stacktrace)

I think, this line, incercari.setText(valIncercari); throws Exception because valIncercari is int

So it should be,

incercari.setText(valIncercari+"");

Or

incercari.setText(Integer.toString(valIncercari));

This works in xCode v6.2, I think that's Swift v1.2

func input() -> String {
    var keyboard = NSFileHandle.fileHandleWithStandardInput()
    var inputData = keyboard.availableData
    return NSString(data: inputData, encoding:NSUTF8StringEncoding)! as String
}

The solution I've been using for a few years now:

@echo off
rem Refresh PATH from registry.
setlocal
set USR_PATH=
set SYS_PATH=
for /F "tokens=3* skip=2" %%P in ('%SystemRoot%\system32\reg.exe query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATH') do @set "SYS_PATH=%%P %%Q"
for /F "tokens=3* skip=2" %%P in ('%SystemRoot%\system32\reg.exe query "HKCU\Environment" /v PATH') do @set "USR_PATH=%%P %%Q"
if "%SYS_PATH:~-1%"==" " set "SYS_PATH=%SYS_PATH:~0,-1%"
if "%USR_PATH:~-1%"==" " set "USR_PATH=%USR_PATH:~0,-1%"
endlocal & call set "PATH=%SYS_PATH%;%USR_PATH%"
goto :EOF

Edit: Woops, here's the updated version.

This SQL query gives output similar to \dx:

SELECT e.extname AS "Name", e.extversion AS "Version", n.nspname AS "Schema", c.description AS "Description" 
FROM pg_catalog.pg_extension e 
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = e.extnamespace 
LEFT JOIN pg_catalog.pg_description c ON c.objoid = e.oid AND c.classoid = 'pg_catalog.pg_extension'::pg_catalog.regclass 
ORDER BY 1;

There are (at least) two things you can do here–you can reclone the remote repo, or you can reset --hard to the common ancestor and then do a pull, which will fast-forward to the latest commit on the remote master.

To be concrete, here's a simple extension of Nevik Rehnel's original answer:

git reset --hard origin/master
git pull origin master

NOTE: using git reset --hard will discard any uncommitted changes, and it can be easy to confuse yourself with this command if you're new to git, so make sure you have a sense of what it is going to do before proceeding.

I usually set the width of my inputs to 99% to fix this:

input {
    width: 99%;
}

You can also remove the default styles, but that will make it less obvious that it is a text box. However, I will show the code for that anyway:

input {
    width: 100%;
    border-width: 0;
    margin: 0;
    padding: 0;
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
}

You can try this:

int cleft = 1;
intaleft = 1;
private void button2_Click(object sender, EventArgs e) 
{
     TextBox txt = new TextBox();
     this.Controls.Add(txt);
     txt.Top = cleft * 40;
     txt.Size = new Size(200, 16);
     txt.Left = 150;
     cleft = cleft + 1;
     Label lbl = new Label();
     this.Controls.Add(lbl);
     lbl.Top = aleft * 40;
     lbl.Size = new Size(100, 16);
     lbl.ForeColor = Color.Blue;
     lbl.Text = "BoxNo/CardNo";
     lbl.Left = 70;
     aleft = aleft + 1;
     return;
}
private void btd_Click(object sender, EventArgs e)
{ 
    //Here you Delete Text Box One By One(int ix for Text Box)
    for (int ix = this.Controls.Count - 2; ix >= 0; ix--)
    //Here you Delete Lable One By One(int ix for Lable)
    for (int x = this.Controls.Count - 2; x >= 0; x--)
    {
        if (this.Controls[ix] is TextBox) 
        this.Controls[ix].Dispose();
        if (this.Controls[x] is Label) 
        this.Controls[x].Dispose();
        return;
    }
}

The easiest way I have found to do it is like this:

dict_count = len(dict_list)
df = pd.DataFrame(dict_list[0], index=[0])
for i in range(1,dict_count-1):
    df = df.append(dict_list[i], ignore_index=True)

Perhaps I misunderstood the question but doesn't this do it?

int NumDigits(int x)  
{  
    x = abs(x);  
    return (x < 10 ? 1 :   
        (x < 100 ? 2 :   
        (x < 1000 ? 3 :   
        (x < 10000 ? 4 :   
        (x < 100000 ? 5 :   
        (x < 1000000 ? 6 :   
        (x < 10000000 ? 7 :  
        (x < 100000000 ? 8 :  
        (x < 1000000000 ? 9 :  
        10)))))))));  
}  

All of these answers are wrong!

Like I said in my comment, the reason you're getting that error because the URL fails the "Same origin policy", but you can still us the AJAX function to hit another domain, see Nick Cravers answer on this similar question:

You need to trigger JSONP behavior with $.getJSON() by adding &callback=? on the querystring, like this:

$.getJSON("http://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=content&titles="+title+"&format=json&callback=?",
function(data) {
    doSomethingWith(data); 
}); 

You can test it here.

Without using JSONP you're hitting the same-origin policy which is blocking the XmlHttpRequest from getting any data back.

With this in mind, the follow code should work:

var fbURL="https://graph.facebook.com/16453004404_481759124404/comments?access_token=my_token";

$.ajax({
    url: fbURL+"&callback=?",
    data: "message="+commentdata,
    type: 'POST',
    success: function (resp) {
        alert(resp);
    },
    error: function(e) {
        alert('Error: '+e);
    }  
});

DB_CLOSE_DELAY=-1

hbm2ddl closes the connection after creating the table, so h2 discards it.

If you have your connection-url configured like this

jdbc:h2:mem:test

the content of the database is lost at the moment the last connection is closed.

If you want to keep your content you have to configure the url like this

jdbc:h2:mem:test;DB_CLOSE_DELAY=-1

If doing so, h2 will keep its content as long as the vm lives.

Notice the semicolon (;) rather than colon (:).

See the In-Memory Databases section of the Features page. To quote:

By default, closing the last connection to a database closes the database. For an in-memory database, this means the content is lost. To keep the database open, add ;DB_CLOSE_DELAY=-1 to the database URL. To keep the content of an in-memory database as long as the virtual machine is alive, use jdbc:h2:mem:test;DB_CLOSE_DELAY=-1.

PDFsharp seems to allow merging multiple PDF documents into one.

And the same is also possible with ITextSharp.

Let MySql convert your unix timestamp to string. Use the mysql function FROM_UNIXTIME( 113283901 )

From the dojo API documentation:

dojo.html._emptyNode(node);

Integer is an wrapper class/Object and int is primitive type. This difference plays huge role when you want to store int values in a collection, because they accept only objects as values (until jdk1.4). JDK5 onwards because of autoboxing it is whole different story.

You could also do:

   if [ "${FILE##*.}" = "txt" ]; then
       # operation for txt files here
   fi

You will want to use a CONVERT() statement.

Try the following;

SELECT CONVERT(VARCHAR(10), SA.[RequestStartDate], 103) as 'Service Start Date', CONVERT(VARCHAR(10), SA.[RequestEndDate], 103) as 'Service End Date', FROM (......) SA WHERE.....

See MSDN Cast and Convert for more information.

Fn + Up/Down can scroll Terminal in Mac OS X 10.11

Here's a straightforward and generic example.

The filter:

sampleApp.filter('unique', function() {

  // Take in the collection and which field
  //   should be unique
  // We assume an array of objects here
  // NOTE: We are skipping any object which
  //   contains a duplicated value for that
  //   particular key.  Make sure this is what
  //   you want!
  return function (arr, targetField) {

    var values = [],
        i, 
        unique,
        l = arr.length, 
        results = [],
        obj;

    // Iterate over all objects in the array
    // and collect all unique values
    for( i = 0; i < arr.length; i++ ) {

      obj = arr[i];

      // check for uniqueness
      unique = true;
      for( v = 0; v < values.length; v++ ){
        if( obj[targetField] == values[v] ){
          unique = false;
        }
      }

      // If this is indeed unique, add its
      //   value to our values and push
      //   it onto the returned array
      if( unique ){
        values.push( obj[targetField] );
        results.push( obj );
      }

    }
    return results;
  };
})

<div ng-repeat = "item in items | unique:'name'">
  {{ item.name }}
</div>
<script src="your/filters.js"></script>

subprocess.Popen does exactly what you want.

from subprocess import Popen
p = Popen(['watch', 'ls']) # something long running
# ... do other stuff while subprocess is running
p.terminate()

(Edit to complete the answer from comments)

The Popen instance can do various other things like you can poll() it to see if it is still running, and you can communicate() with it to send it data on stdin, and wait for it to terminate.

After a bit of experimentation, I found the following example using fs.stat to be a good way to asynchronously check whether a file exists. It also checks that your "file" is "really-is-a-file" (and not a directory).

This method uses Promises, assuming that you are working with an asynchronous codebase:

const fileExists = path => {
  return new Promise((resolve, reject) => {
    try {
      fs.stat(path, (error, file) => {
        if (!error && file.isFile()) {
          return resolve(true);
        }

        if (error && error.code === 'ENOENT') {
          return resolve(false);
        }
      });
    } catch (err) {
      reject(err);
    }
  });
};

If the file does not exist, the promise still resolves, albeit false. If the file does exist, and it is a directory, then is resolves true. Any errors attempting to read the file will reject the promise the error itself.

Use your bean class like this, if your JSON data starts with an an array object. it helps you.

Users[] bean = gson.fromJson(response,Users[].class);

Users is my bean class.

Response is my JSON data.

Just put a '!' in front of the boolean expression

If you're a C# / Java / C++ / Ruby / Python / Pick-A-Language-From-This-Century developer and you want to call your function with commas, because that's what you've always done, then you need something like this:

$myModule = New-Module -ascustomobject { 
    function test($arg1, $arg2) { 
        echo "arg1 = $arg1, and arg2 = $arg2"
    }
}

Now call:

$myModule.test("ABC", "DEF")

and you'll see

arg1 = ABC, and arg2 = DEF

Look for exceptions being thrown and caught in the ... sections of your code. Runtime and rollbacking application exceptions cause rollback when thrown out of a business method even if caught on some other place.

You can use context to find out whether the transaction is marked for rollback.

@Resource
private SessionContext context;

context.getRollbackOnly();

It's even easier to do without a library

window.onload = function() {
    // code
};

When you just want to execute one or several HTTP requests without having to wait for the response, there is a simple PHP solution, as well.

In the calling script:

$socketcon = fsockopen($host, 80, $errno, $errstr, 10);
if($socketcon) {   
   $socketdata = "GET $remote_house/script.php?parameters=... HTTP 1.1\r\nHost: $host\r\nConnection: Close\r\n\r\n";      
   fwrite($socketcon, $socketdata); 
   fclose($socketcon);
}
// repeat this with different parameters as often as you like

On the called script.php, you can invoke these PHP functions in the first lines:

ignore_user_abort(true);
set_time_limit(0);

This causes the script to continue running without time limit when the HTTP connection is closed.

You're getting the toString() value returned by the Scanner object itself which is not what you want and not how you use a Scanner object. What you want instead is the data obtained by the Scanner object. For example,

Scanner input = new Scanner(System.in);
String data = input.nextLine();
System.out.println(data);

Please read the tutorial on how to use it as it will explain all.

Edit
Please look here: Scanner tutorial

Also have a look at the Scanner API which will explain some of the finer points of Scanner's methods and properties.

This tells you the date of the number of seconds in future from the moment you execute the code.

time = Time.new + 1000000000 #date in 1 billion seconds

puts(time)

according to the current time I am answering the question it prints 047-05-14 05:16:16 +0000 (1 billion seconds in future)

or if you want to count billion seconds from a particular time, it's in format Time.mktime(year, month,date,hours,minutes)

time = Time.mktime(1987,8,18,6,45) + 1000000000

puts("I would be 1 Billion seconds old on: "+time)

This article by Andre Staltz is the best and clearest explanation I've seen so far.

Some quotes from the article:

Reactive programming is programming with asynchronous data streams.

On top of that, you are given an amazing toolbox of functions to combine, create and filter any of those streams.

Here's an example of the fantastic diagrams that are a part of the article:

The short version is: The efficient way to use readlines() is to not use it. Ever.

I read some doc notes on readlines(), where people has claimed that this readlines() reads whole file content into memory and hence generally consumes more memory compared to readline() or read().

The documentation for readlines() explicitly guarantees that it reads the whole file into memory, and parses it into lines, and builds a list full of strings out of those lines.

But the documentation for read() likewise guarantees that it reads the whole file into memory, and builds a string, so that doesn't help.

On top of using more memory, this also means you can't do any work until the whole thing is read. If you alternate reading and processing in even the most naive way, you will benefit from at least some pipelining (thanks to the OS disk cache, DMA, CPU pipeline, etc.), so you will be working on one batch while the next batch is being read. But if you force the computer to read the whole file in, then parse the whole file, then run your code, you only get one region of overlapping work for the entire file, instead of one region of overlapping work per read.

You can work around this in three ways:

1. Write a loop around readlines(sizehint), read(size), or readline().
2. Just use the file as a lazy iterator without calling any of these.
3. mmap the file, which allows you to treat it as a giant string without first reading it in.

For example, this has to read all of foo at once:

with open('foo') as f:
    lines = f.readlines()
    for line in lines:
        pass

But this only reads about 8K at a time:

with open('foo') as f:
    while True:
        lines = f.readlines(8192)
        if not lines:
            break
        for line in lines:
            pass

And this only reads one line at a time—although Python is allowed to (and will) pick a nice buffer size to make things faster.

with open('foo') as f:
    while True:
        line = f.readline()
        if not line:
            break
        pass

And this will do the exact same thing as the previous:

with open('foo') as f:
    for line in f:
        pass

Meanwhile:

but should the garbage collector automatically clear that loaded content from memory at the end of my loop, hence at any instant my memory should have only the contents of my currently processed file right ?

Python doesn't make any such guarantees about garbage collection.

The CPython implementation happens to use refcounting for GC, which means that in your code, as soon as file_content gets rebound or goes away, the giant list of strings, and all of the strings within it, will be freed to the freelist, meaning the same memory can be reused again for your next pass.

However, all those allocations, copies, and deallocations aren't free—it's much faster to not do them than to do them.

On top of that, having your strings scattered across a large swath of memory instead of reusing the same small chunk of memory over and over hurts your cache behavior.

Plus, while the memory usage may be constant (or, rather, linear in the size of your largest file, rather than in the sum of your file sizes), that rush of mallocs to expand it the first time will be one of the slowest things you do (which also makes it much harder to do performance comparisons).

Putting it all together, here's how I'd write your program:

for filename in os.listdir(input_dir):
    with open(filename, 'rb') as f:
        if filename.endswith(".gz"):
            f = gzip.open(fileobj=f)
        words = (line.split(delimiter) for line in f)
        ... my logic ...  

Or, maybe:

for filename in os.listdir(input_dir):
    if filename.endswith(".gz"):
        f = gzip.open(filename, 'rb')
    else:
        f = open(filename, 'rb')
    with contextlib.closing(f):
        words = (line.split(delimiter) for line in f)
        ... my logic ...

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

You would do that when the responsibility of creating/updating the referenced column isn't in the current entity, but in another entity.

I've solved this problem using JDK 7 with this code:

    public static void main(String[] args) {

        File file = new File("c:\\1.txt");
        Path filePath = file.toPath();

        BasicFileAttributes attributes = null;
        try
        {
            attributes =
                    Files.readAttributes(filePath, BasicFileAttributes.class);
        }
        catch (IOException exception)
        {
            System.out.println("Exception handled when trying to get file " +
                    "attributes: " + exception.getMessage());
        }
        long milliseconds = attributes.creationTime().to(TimeUnit.MILLISECONDS);
        if((milliseconds > Long.MIN_VALUE) && (milliseconds < Long.MAX_VALUE))
        {
            Date creationDate =
                    new Date(attributes.creationTime().to(TimeUnit.MILLISECONDS));

            System.out.println("File " + filePath.toString() + " created " +
                    creationDate.getDate() + "/" +
                    (creationDate.getMonth() + 1) + "/" +
                    (creationDate.getYear() + 1900));

RegEx match open tags except XHTML self-contained tags
All other tags (and content) are skipped.

This regex does that. If you need to match only specific Open tags, make a list
in an alternation (?:p|br|<whatever tags you want>) and replace the [\w:]+ construct
in the appropriate place below.

<(?:(?:(?:(script|style|object|embed|applet|noframes|noscript|noembed)(?:\s+(?>"[\S\s]*?"|'[\S\s]*?'|(?:(?!/>)[^>])?)+)?\s*>)[\S\s]*?</\1\s*(?=>)(*SKIP)(*FAIL))|(?:[\w:]+\b(?=((?:"[\S\s]*?"|'[\S\s]*?'|[^>]?)*)>)\2(?<!/))|(?:(?:/?[\w:]+\s*/?)|(?:[\w:]+\s+(?:"[\S\s]*?"|'[\S\s]*?'|[^>]?)+\s*/?)|\?[\S\s]*?\?|(?:!(?:(?:DOCTYPE[\S\s]*?)|(?:\[CDATA\[[\S\s]*?\]\])|(?:--[\S\s]*?--)|(?:ATTLIST[\S\s]*?)|(?:ENTITY[\S\s]*?)|(?:ELEMENT[\S\s]*?))))(*SKIP)(*FAIL))>

In my apps I have a class which wraps the Log class which has a static boolean var called "state". Throughout my code I check the value of the "state" variable using a static method before actually writing to the Log. I then have a static method to set the "state" variable which ensures the value is common across all instances created by the app. This means I can enable or disable all logging for the App in one call - even when the App is running. Useful for support calls... It does mean that you have to stick to your guns when debugging and not regress to using the standard Log class though...

It's also useful (convenient) that Java interprets a boolean var as false if it hasn't been assigned a value, which means it can be left as false until you need to turn on logging :-)

Probably git reset solves your problem.

Use subshell:

echo "$(echo -n 'hello'; cat filename)" > filename

Unfortunately, command substitution will remove newlines at the end of file. So as to keep them one can use:

echo -n "hello" | cat - filename > /tmp/filename.tmp
mv /tmp/filename.tmp filename

Neither grouping nor command substitution is needed.

<select name="selectedFacilityId" ng-model="selectedFacilityId">

This is an example on how to use it.

You can just concatenate them.

SET REL_PATH=..\SomeFile.txt
SET COMBINED_PATH=%ABS_PATH%%REL_PATH%

it looks odd with \..\ in the middle of your path but it works. No need to do anything crazy :)

Maybe I am missing something (lots of many-upvotes-members answers here that seem to be looking at this different to I, which would seem implausible that I am correct), but length is not the correct terminology for counting something. Length is usually used to obtain what you are getting, and not what you are wanting.

$cars.count should give you what you seem to be looking for.

The two common approaches are to submit the form to an invisible iframe, or to use a Flash control such as YUI Uploader. You could also use Java instead of Flash, but this has a narrower install base.

I fixed it by changing Mach-O Type under linking section on the Build settings from Nothing to Executable.

ClickOnce apps are designed so that the end user downloads a "downloader" - the ClickOnce app, then when ya run it, it downloads and installs in %LocalAppData%\Apps\2.0..... and then it's random folder names for every OS install you do. Backing up is pointless and so is trying to move the program. The point of ClickOnce is 2-Fold: 1. AutoUpdating of the program 2. The end user has no installer and also can't move the app or it breaks

The %LocalAppData%\Apps\2.0..... folder is the program AND %LocalAppData%\GitHub is the settings folder.

I'm not going to cover how to circumvent this - only stating the above. :P

The best 'tip' I can say legitimately is: You 'can' in some cases move the final folder that all the files are in and use a symlink back, if you are low on space. But, not all apps will work and essentially will delete the symlink once you they run. Then they might reinstall or simply just remove the link. Keep in mind also, other apps may be using that same final folder as well, so move the folder will affect those too.

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

If you do not want to configure the message converters yourself, you can use either @EnableWebMvc or <mvc:annotation-driven />, add Jackson to the classpath and Spring will give you both JSON, XML (and a few other converters) by default. Additionally, you will get some other commonly used features for conversion, formatting and validation.

The main alternative is:

• CodeRush, by DevExpress. Most consider either this or ReSharper the way to go. You cannot go wrong with either. Both have their fans, both are powerful, and both have talented teams constantly improving them. We have all benefited from the competition between these two. I won't repeat the many good discussions/comparisons about them that can be found on Stack Overflow and elsewhere.

Another alternative worth checking out:

• JustCode, by Telerik. This is new, still with kinks, but initial reports are positive. An advantage could be licensing with other Telerik products and integration with them. There are bundled licenses available that could make things cheaper / easier to handle.

Using a unique_ptr might be OK.
You then reset it to obtain an empty queue and release the memory of the first queue. As to the complexity? I'm not sure - but guess it's O(1).

Possible code:

typedef queue<int> quint;

unique_ptr<quint> p(new quint);

// ...

p.reset(new quint);  // the old queue has been destroyed and you start afresh with an empty queue

Make sure Qt5Core.dll is in the same directory with your application executable.

I had a similar issue in Qt5 with a console application: if I start the application from Qt Creator, the output text is visible, if I open cmd.exe and start the same application there, no output is visible. Very strange!

I solved it by copying Qt5Core.dll to the directory with the application executable.

Here is my tiny console application:

#include <QCoreApplication>
#include <QDebug>

int main(int argc, char *argv[])
{
    int x=343;
    QString str("Hello World");
    qDebug()<< str << x<<"lalalaa";

    QTextStream out(stdout);
    out << "aldfjals alsdfajs...";
}

 cd ~/.janus/snipmate-snippets

See commit 091a6eb0feed820a43663ca63dc2bc0bb247bbae:

submodule: drop the top-level requirement

Use the new rev-parse --prefix option to process all paths given to the submodule command, dropping the requirement that it be run from the top-level of the repository.

Since the interpretation of a relative submodule URL depends on whether or not "remote.origin.url" is configured, explicitly block relative URLs in "git submodule add" when not at the top level of the working tree.

Depends on commit 12b9d32790b40bf3ea49134095619700191abf1f

This makes 'git rev-parse' behave as if it were invoked from the specified subdirectory of a repository, with the difference that any file paths which it prints are prefixed with the full path from the top of the working tree.

This is useful for shell scripts where we may want to cd to the top of the working tree but need to handle relative paths given by the user on the command line.

Trim() Removes all leading and trailing white-space characters from the current string. Trim(Char) Removes all leading and trailing instances of a character from the current string. Trim(Char[]) Removes all leading and trailing occurrences of a set of characters specified in an array from the current string.

Look at the following example that I quoted from Microsoft's documentation page.

char[] charsToTrim = { '*', ' ', '\''};
string banner = "*** Much Ado About Nothing ***";
string result = banner.Trim(charsToTrim);
Console.WriteLine("Trimmmed\n   {0}\nto\n   '{1}'", banner, result);

// The example displays the following output:
//       Trimmmed
//          *** Much Ado About Nothing ***
//       to
//          'Much Ado About Nothing'

It's all about the key bindings which one can simply achieve from .vimrc configurations. As far as clipboard is concerned you can use :set clipboard unnamed and the yank from vim will go to system clipboard. Anyways, whichever one you end up using I suggest using this vimrc config , it contains a whole lot of plugins and bindings which will make your experience smooth.

both <button> tag and <input type="button"> accept a title attribute..

Just in case you actually mean 'discard changes' whenever you use 'git stash' (and don't really use git stash to stash it temporarily), in that case you can use

If you are just wandering over the collection to read all of the values, then there is no difference between using an iterator or the new for loop syntax, as the new syntax just uses the iterator underwater.

If however, you mean by loop the old "c-style" loop:

for(int i=0; i<list.size(); i++) {
   Object o = list.get(i);
}

Then the new for loop, or iterator, can be a lot more efficient, depending on the underlying data structure. The reason for this is that for some data structures, get(i) is an O(n) operation, which makes the loop an O(n²) operation. A traditional linked list is an example of such a data structure. All iterators have as a fundamental requirement that next() should be an O(1) operation, making the loop O(n).

To verify that the iterator is used underwater by the new for loop syntax, compare the generated bytecodes from the following two Java snippets. First the for loop:

List<Integer>  a = new ArrayList<Integer>();
for (Integer integer : a)
{
  integer.toString();
}
// Byte code
 ALOAD 1
 INVOKEINTERFACE java/util/List.iterator()Ljava/util/Iterator;
 ASTORE 3
 GOTO L2
L3
 ALOAD 3
 INVOKEINTERFACE java/util/Iterator.next()Ljava/lang/Object;
 CHECKCAST java/lang/Integer
 ASTORE 2 
 ALOAD 2
 INVOKEVIRTUAL java/lang/Integer.toString()Ljava/lang/String;
 POP
L2
 ALOAD 3
 INVOKEINTERFACE java/util/Iterator.hasNext()Z
 IFNE L3

And second, the iterator:

List<Integer>  a = new ArrayList<Integer>();
for (Iterator iterator = a.iterator(); iterator.hasNext();)
{
  Integer integer = (Integer) iterator.next();
  integer.toString();
}
// Bytecode:
 ALOAD 1
 INVOKEINTERFACE java/util/List.iterator()Ljava/util/Iterator;
 ASTORE 2
 GOTO L7
L8
 ALOAD 2
 INVOKEINTERFACE java/util/Iterator.next()Ljava/lang/Object;
 CHECKCAST java/lang/Integer
 ASTORE 3
 ALOAD 3
 INVOKEVIRTUAL java/lang/Integer.toString()Ljava/lang/String;
 POP
L7
 ALOAD 2
 INVOKEINTERFACE java/util/Iterator.hasNext()Z
 IFNE L8

As you can see, the generated byte code is effectively identical, so there is no performance penalty to using either form. Therefore, you should choose the form of loop that is most aesthetically appealing to you, for most people that will be the for-each loop, as that has less boilerplate code.

imperative and declarative describe two opposing styles of programming. imperative is the traditional "step by step recipe" approach while declarative is more "this is what i want, now you work out how to do it".

these two approaches occur throughout programming - even with the same language and the same program. generally the declarative approach is considered preferable, because it frees the programmer from having to specify so many details, while also having less chance for bugs (if you describe the result you want, and some well-tested automatic process can work backwards from that to define the steps then you might hope that things are more reliable than having to specify each step by hand).

on the other hand, an imperative approach gives you more low level control - it's the "micromanager approach" to programming. and that can allow the programmer to exploit knowledge about the problem to give a more efficient answer. so it's not unusual for some parts of a program to be written in a more declarative style, but for the speed-critical parts to be more imperative.

as you might imagine, the language you use to write a program affects how declarative you can be - a language that has built-in "smarts" for working out what to do given a description of the result is going to allow a much more declarative approach than one where the programmer needs to first add that kind of intelligence with imperative code before being able to build a more declarative layer on top. so, for example, a language like prolog is considered very declarative because it has, built-in, a process that searches for answers.

so far, you'll notice that i haven't mentioned functional programming. that's because it's a term whose meaning isn't immediately related to the other two. at its most simple, functional programming means that you use functions. in particular, that you use a language that supports functions as "first class values" - that means that not only can you write functions, but you can write functions that write functions (that write functions that...), and pass functions to functions. in short - that functions are as flexible and common as things like strings and numbers.

it might seem odd, then, that functional, imperative and declarative are often mentioned together. the reason for this is a consequence of taking the idea of functional programming "to the extreme". a function, in it's purest sense, is something from maths - a kind of "black box" that takes some input and always gives the same output. and that kind of behaviour doesn't require storing changing variables. so if you design a programming language whose aim is to implement a very pure, mathematically influenced idea of functional programming, you end up rejecting, largely, the idea of values that can change (in a certain, limited, technical sense).

and if you do that - if you limit how variables can change - then almost by accident you end up forcing the programmer to write programs that are more declarative, because a large part of imperative programming is describing how variables change, and you can no longer do that! so it turns out that functional programming - particularly, programming in a functional language - tends to give more declarative code.

to summarise, then:

• imperative and declarative are two opposing styles of programming (the same names are used for programming languages that encourage those styles)

• functional programming is a style of programming where functions become very important and, as a consequence, changing values become less important. the limited ability to specify changes in values forces a more declarative style.

so "functional programming" is often described as "declarative".

I use MinGW tool set which provides mingw32-make build tool, if you have it in your PATH system variables, in Windows Command Prompt just go into the directory containing the files and type this command:

You application of js and php in totally invalid.

You have to understand a fact that JS runs on clientside, once the page loads it does not care, whether the page was a php page or jsp or asp. It executes of DOM and is related to it only.

However you can do something like this

var newLocation = "<?php echo $newlocation; ?>";
window.location = newLocation;

You see, by the time the script is loaded, the above code renders into different form, something like this

var newLocation = "your/redirecting/page.php";
window.location = newLocation;

Like above, there are many possibilities of php and js fusions and one you are doing is not one of them.

This method worked in my case.

video=getElementsByTagName('video');
function removeControls(video){
  video.removeAttribute('controls');
}
window.onload=removeControls(video);

}
?>

To create list of lists, you need to separate them with commas, like this

coin_args = [
    ["pennies", '2.5', '50.0', '.01'],
    ["nickles", '5.0', '40.0', '.05'],
    ["dimes", '2.268', '50.0', '.1'],
    ["quarters", '5.67', '40.0', '.25']
]

On Windows, you can also use the Win32 File Namespace prefixed with \\?\ to refer to your local directories:

\\?\C:\my_dir

If you really need to override css that has !important rules in it, for instance, in a case I ran into recently, overriding a wordpress theme required !important scss rules to break the theme, but since I was transpiling my code with webpack and (I assume this is why --)my css came along in the chain after the transpiled javascript, you can add a separate class rule in your stylesheet that overrides the first !important rule in the cascade, and toggle the heavier-weighted class rather than adjusting css dynamically. Just a thought.

An alternative is to use

You could always try the Synth look & feel. You provide an xml file that acts as a sort of stylesheet, along with any images you want to use. The code might look like this:

try {
    SynthLookAndFeel synth = new SynthLookAndFeel();
    Class aClass = MainFrame.class;
    InputStream stream = aClass.getResourceAsStream("\\default.xml");

    if (stream == null) {
        System.err.println("Missing configuration file");
        System.exit(-1);                
    }

    synth.load(stream, aClass);

    UIManager.setLookAndFeel(synth);
} catch (ParseException pe) {
    System.err.println("Bad configuration file");
    pe.printStackTrace();
    System.exit(-2);
} catch (UnsupportedLookAndFeelException ulfe) {
    System.err.println("Old JRE in use. Get a new one");
    System.exit(-3);
}

From there, go on and add your JButton like you normally would. The only change is that you use the setName(string) method to identify what the button should map to in the xml file.

The xml file might look like this:

<synth>
    <style id="button">
        <font name="DIALOG" size="12" style="BOLD"/>
        <state value="MOUSE_OVER">
            <imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
            <insets top="2" botton="2" right="2" left="2"/>
        </state>
        <state value="ENABLED">
            <imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
            <insets top="2" botton="2" right="2" left="2"/>
        </state>
    </style>
    <bind style="button" type="name" key="dirt"/>
</synth>

The bind element there specifies what to map to (in this example, it will apply that styling to any buttons whose name property has been set to "dirt").

As @Malvineous said, It's not professional but a work-around to use the Find/Replace method to remove trailing space (below including tab U+0009 and whitespace U+0020).
Just press Ctrl + F (or command + F)

1. Find [\t ][\t ]*$
   
2. Replace with blank string
   
3. Use Regular expressions
4. Replace All

extra:
For removing leading space, find ^[\t ][\t ]* instead of [\t ][\t ]*$
For removing blank lines, find ^\s*$\r?\n

scp is best for one file.
OR a combination of tar & compression for smaller data sets like source code trees with small resources (ie: images, sqlite etc).

• media folders (40 GB)
• database backups (28 GB)
• mp3 libraries (100 GB)

It becomes impractical to build a zip/tar.gz file to transfer with scp at this point do to the physical limits of the hosted server.

As an exercise, you can do some gymnastics like piping tar into ssh and redirecting the results into a remote file. (saving the need to build a swap or temporary clone aka zip or tar.gz)

However,

rsync simplify's this process and allows you to transfer data without consuming any additional disc space.

Also,

Continuous (cron?) updates use minimal changes vs full cloned copies speed up large data migrations over time.

tl;dr
scp == small scale (with room to build compressed files on the same drive)
rsync == large scale (with the necessity to backup large data and no room left)

If the divs are hidden, they will never trigger the mouseover event.

You will have to listen to the event of some other unhidden element.

You can consider wrapping your hidden divs into container divs that remain visible, and then act on the mouseover event of these containers.

<div style="width: 80px; height: 20px; background-color: red;" _x000D_
        onmouseover="document.getElementById('div1').style.display = 'block';">_x000D_
   <div id="div1" style="display: none;">Text</div>_x000D_
</div>

You could also listen for the mouseout event if you want the div to disappear when the mouse leaves the container div:

onmouseout="document.getElementById('div1').style.display = 'none';"

If you still can not find anything wrong with your setup, you can try Project -> Clean and clean all the projects in the workspace.

EDIT: Sorry, did not see the suggestion of verbose_mode ... same thing

I'm not quite happy with this implementation yet, I wanted to have a custom constructor that does DirectoryIndex._make(next(os.walk(input_path))) such that you can just pass the path you want a file listing for. Edits welcome!

import collections
import os

DirectoryIndex = collections.namedtuple('DirectoryIndex', ['root', 'dirs', 'files'])

for file_name in DirectoryIndex(*next(os.walk('.'))).files:
    file_path = os.path.join(path, file_name)

Simple answer

If you want to match single character, put it inside those brackets [ ]

Examples

• match + ...... [+] or +
• match a ...... a
• match & ...... &

...and so on. You can check your regular expresion online on this site: https://regex101.com/

You should be able to remove it using

outline: none;

but keep in mind this is potentially bad for usability: It will be hard to tell whether an element is focused, which can suck when you walk through all a form's elements using the Tab key - you should reflect somehow when an element is focused.

Here's an example of using the HttpWebRequest class to fetch a URL

private void buttonl_Click(object sender, EventArgs e) 
{ 
    String url = TextBox_url.Text;
    HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url); 
    HttpWebResponse response = (HttpWebResponse) request.GetResponse(); 
    StreamReader sr = new StreamReader(response.GetResponseStream()); 
    richTextBox1.Text = sr.ReadToEnd(); 
    sr.Close(); 
} 

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

the best way (for me) to make it it's the next infrastructure:

<form method="POST">
<input type="submit" formaction="default_url_when_press_enter" style="visibility: hidden; display: none;">
<!-- all your inputs -->
<input><input><input>
<!-- all your inputs -->
<button formaction="action1">Action1</button>
<button formaction="action2">Action2</button>
<input type="submit" value="Default Action">
</form>

with this structure you will send with enter a direction and the infinite possibilities for the rest of buttons.

For my basic case insensitive string comparison needs I prefer not to have to use an external library, nor do I want a separate string class with case insensitive traits that is incompatible with all my other strings.

So what I've come up with is this:

bool icasecmp(const string& l, const string& r)
{
    return l.size() == r.size()
        && equal(l.cbegin(), l.cend(), r.cbegin(),
            [](string::value_type l1, string::value_type r1)
                { return toupper(l1) == toupper(r1); });
}

bool icasecmp(const wstring& l, const wstring& r)
{
    return l.size() == r.size()
        && equal(l.cbegin(), l.cend(), r.cbegin(),
            [](wstring::value_type l1, wstring::value_type r1)
                { return towupper(l1) == towupper(r1); });
}

A simple function with one overload for char and another for whar_t. Doesn't use anything non-standard so should be fine on any platform.

The equality comparison won't consider issues like variable length encoding and Unicode normalization, but basic_string has no support for that that I'm aware of anyway and it isn't normally an issue.

In cases where more sophisticated lexicographical manipulation of text is required, then you simply have to use a third party library like Boost, which is to be expected.
