We actually just upgraded a .NET web service to 4.6 to allow TLS 1.2.

What Artem is saying were the first steps we've done. We recompiled the framework of the web service to 4.6 and we tried change the registry key to enable TLS 1.2, although this didn't work: the connection was still in TLS 1.0. Also, we didn't want to disallow SLL 3.0, TLS 1.0 or TLS 1.1 on the machine: other web services could be using this; we rolled-back our changes on the registry.

We actually changed the Web.Config files to tell IIS: "hey, run me in 4.6 please".

Here's the changes we added in the web.config + recompilation in .NET 4.6:

<system.web>
    <compilation targetFramework="4.6"/> <!-- Changed framework 4.0 to 4.6 -->

    <!--Added this httpRuntime -->
    <httpRuntime targetFramework="4.6" />

    <authentication mode="Windows"/>
    <pages controlRenderingCompatibilityVersion="4.0"/>
</system.web>

And the connection changed to TLS 1.2, because IIS is now running the web service in 4.6 (told explicitly) and 4.6 is using TLS 1.2 by default.

Use modern Js events, with "once"!

const button = document.getElementById(btnId);
button.addEventListener("click", function() {
    // Submit form
}, {once : true});

// Disabling works too, but this is a more standard approach for general one-time events

Solution that Cerin provide, importing each time that this problem happens, could be boring.

So I've implemented a script that control if workspace setting exits: if not, restore it to default.

I have an eclipse shortcut icon on the top panel that execute:

 /opt/eclipse/checkWorkspace && /opt/eclipse/eclipse

Script checkWorkspace is the seguent:

#!/bin/bash

ECLIPSE_CONFIG_PATH="/opt/eclipse/configuration"
ECLIPSE_CONFIG_FILE="config.ini"
ECLIPSE_CONFIG_SETTING="osgi.instance.area.default"
DEFAULT_WORKSPACE_PATH="@user.home/workspace"
ECLIPSE_LOG="/var/log/eclipse.log"

cd ${ECLIPSE_CONFIG_PATH}

function sedeasy {
  sed -i "s/$(echo $1 | sed -e 's/\([[\/.*]\|\]\)/\\&/g')/$(echo $2 | sed -e 's/[\/&]/\\&/g')/g" $3
}

WORKSPACE_EXISTS=$(cat ${ECLIPSE_CONFIG_FILE} | grep ${ECLIPSE_CONFIG_SETTING})

# If workspace setting doesn't exists 
if [ -z "$WORKSPACE_EXISTS" ]; then
  echo "worskspace setting not exists, resetting to default." >> ${ECLIPSE_LOG}
  newConf=${ECLIPSE_CONFIG_SETTING}"="${DEFAULT_WORKSPACE_PATH}
  echo ${newConf} >> ${ECLIPSE_CONFIG_FILE}     
else    
   # if setting exist but it is empty
   vals=(${WORKSPACE_EXISTS//=/ }) 
   length=$(echo ${#vals[@]})
   if [ "${length}" -lt 2 ]; then
       newConf=${ECLIPSE_CONFIG_SETTING}"="${DEFAULT_WORKSPACE_PATH}
       confToReplace=$(echo ${vals[0]})
       sedeasy ${confToReplace} ${newConf} ${ECLIPSE_CONFIG_FILE}
       echo "worskspace exists but is empty, resetting to default." >> ${ECLIPSE_LOG}
   else
      echo "Worskspace already set:" "${vals[1]}"
   fi
fi

Maybe could be semplified, but works.

This might help - Just Download and install the Android SDK version(same as your mobile's android version), then run.

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

Like this

#if defined(LINUX) || defined(ANDROID)

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

Which do you use? The only reason to use IEnumerator is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator. But you'd still need to return that IEnumerator in an IEnumerable class.

For a look at what an enumerator (implementing IEnumerator<T>) looks like, see any Enumerator<T> class, such as the ones contained in List<T>, Queue<T>, or Stack<T>. For a look at a class implementing IEnumerable, see any standard collection class.

Also be sure to check out \H, which toggles HTML output on/off. Not necessarily easy to read at the console, but interesting for dumping into a file (see \o) or pasting into an editor/browser window for viewing, especially with multiple rows of relatively complex data.

Using Visual Studio (2012) I had the same issue and switching to IIS Express solved the problem!

The script tag's type attribute did not factor into it.

For some reason the Visual Studio Development Server does not provide everything Chrome needs to enable the breakpoints.

I suggest you not use literals.

Other than that the style itself looks fine.

In my case there was no DEFINER or root@localhost mentioned in my SQL file. Actually I was trying to import and run SQL file into SQLYog from Database->Import->Execute SQL Script menu. That was giving error.

Then I copied all the script from SQL file and ran in SQLYog query editor. That worked perfectly fine.

You could round down the time.

Using ROUND below will round it down to midnight.

WHERE Orders.OrderStatus = 'Shipped'  
AND Orders.ShipDate >  CONVERT(datetime, (ROUND(convert(float, getdate()-6.5),0)))

How about you simply use vh which stands for view height in CSS...

Look at the code snippet I created for you below and run it:

body {_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.full-height {_x000D_
  width: 100px;_x000D_
  height: 100vh;_x000D_
  background: red;_x000D_
}

<div class="full-height">_x000D_
</div>

Also, look at the image below which I created for you:

For anyone who does not want to implement the monstrous click handling. You can achieve the same with a RelativeLayout. With that you even have free handling of the positioning of the drawable.

  <RelativeLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content">

   <android.support.design.widget.TextInputLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

     <android.support.design.widget.TextInputEditText
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
      />
     </android.support.design.widget.TextInputLayout>
     <ImageView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_alignParentEnd="true"
       android:layout_centerInParent="true"
       android:src="@drawable/ic_undo"/>
    </RelativeLayout>

The ImageView position will be the same as you would use drawableEnd - plus you don't need all the touch listener handling. Just a click listener for the ImageView and you are good to go.

Depends on the situation. If it is a special case, then return null. If the function just happens to return an empty collection, then obviously returning that is ok. However, returning an empty collection as a special case because of invalid parameters or other reasons is NOT a good idea, because it is masking a special case condition.

Actually, in this case I usually prefer to throw an exception to make sure it is REALLY not ignored :)

Saying that it makes the code more robust (by returning an empty collection) as they do not have to handle the null condition is bad, as it is simply masking a problem that should be handled by the calling code.

Pretty good documentation is provided on the MongoDB website

Install MongoDB

1. Determine which MongoDB build you need.

   There are three builds of MongoDB for Windows:

   MongoDB for Windows Server 2008 R2 edition (i.e. 2008R2) runs only on Windows Server 2008 R2, Windows 7 64-bit, and newer versions of Windows. This build takes advantage of recent enhancements to the Windows Platform and cannot operate on older versions of Windows.

   MongoDB for Windows 64-bit runs on any 64-bit version of Windows newer than Windows XP, including Windows Server 2008 R2 and Windows 7 64-bit.

   MongoDB for Windows 32-bit runs on any 32-bit version of Windows newer than Windows XP. 32-bit versions of MongoDB are only intended for older systems and for use in testing and development systems. 32-bit versions of MongoDB only support databases smaller than 2GB.

   To find which version of Windows you are running, enter the following command in the Command Prompt:

   wmic os get osarchitecture
   

2. Download MongoDB for Windows.

   Download the latest production release of MongoDB from the MongoDB downloads page. Ensure you download the correct version of MongoDB for your Windows system. The 64-bit versions of MongoDB does not work with 32-bit Windows.

3. Install the downloaded file.

   In Windows Explorer, locate the downloaded MongoDB msi file, which typically is located in the default Downloads folder. Double-click the msi file. A set of screens will appear to guide you through the installation process.

4. Move the MongoDB folder to another location (optional).

   To move the MongoDB folder, you must issue the move command as an Administrator. For example, to move the folder to C:\mongodb:

   Select Start Menu > All Programs > Accessories.

   Right-click Command Prompt and select Run as Administrator from the popup menu.

   Issue the following commands:

   cd \
   move C:\mongodb-win32-* C:\mongodb
   

   MongoDB is self-contained and does not have any other system dependencies. You can run MongoDB from any folder you choose. You may install MongoDB in any folder (e.g. D:\test\mongodb)

Run MongoDB

Warning:

Do not make mongod.exe visible on public networks without running in “Secure Mode” with the auth setting. MongoDB is designed to be run in trusted environments, and the database does not enable “Secure Mode” by default.

1. Set up the MongoDB environment.

   MongoDB requires a data directory to store all data. MongoDB’s default data directory path is \data\db. Create this folder using the following commands from a Command Prompt:

   md \data\db
   

   You can specify an alternate path for data files using the --dbpath option to mongod.exe, for example:

   C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
   

   If your path includes spaces, enclose the entire path in double quotes, for example:

   C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
   

2. Start MongoDB.

   To start MongoDB, run mongod.exe. For example, from the Command Prompt:

   C:\Program Files\MongoDB\bin\mongod.exe
   

   This starts the main MongoDB database process. The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.

   Depending on the security level of your system, Windows may pop up a Security Alert dialog box about blocking “some features” of C:\Program Files\MongoDB\bin\mongod.exe from communicating on networks. All users should select Private Networks, such as my home or work network and click Allow access. For additional information on security and MongoDB, please see the Security Documentation.

3. Connect to MongoDB.

   To connect to MongoDB through the mongo.exe shell, open another Command Prompt. When connecting, specify the data directory if necessary. This step provides several example connection commands.

   If your MongoDB installation uses the default data directory, connect without specifying the data directory:

   C:\mongodb\bin\mongo.exe
   

   If you installation uses a different data directory, specify the directory when connecting, as in this example:

   C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
   

   If your path includes spaces, enclose the entire path in double quotes. For example:

   C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
   

   If you want to develop applications using .NET, see the documentation of C# and MongoDB for more information.

4. Begin using MongoDB.

   To begin using MongoDB, see Getting Started with MongoDB. Also consider the Production Notes document before deploying MongoDB in a production environment.

   Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.

Configure a Windows Service for MongoDB

Note:

There is a known issue for MongoDB 2.6.0, SERVER-13515, which prevents the use of the instructions in this section. For MongoDB 2.6.0, use Manually Create a Windows Service for MongoDB to create a Windows Service for MongoDB instead.

1. Configure directories and files.

   Create a configuration file and a directory path for MongoDB log output (logpath):

   Create a specific directory for MongoDB log files:

   md "C:\Program Files\MongoDB\log"
   

   In the Command Prompt, create a configuration file for the logpath option for MongoDB:

   echo logpath=C:\Program Files\MongoDB\log\mongo.log > "C:\Program Files\MongoDB\mongod.cfg"
   

2. Run the MongoDB service.

   Run all of the following commands in Command Prompt with “Administrative Privileges:”

   Install the MongoDB service. For --install to succeed, you must specify the logpath run-time option.

   "C:\Program Files\MongoDB\bin\mongod.exe" --config "C:\Program Files\MongoDB\mongod.cfg" --install
   

   Modify the path to the mongod.cfg file as needed.

   To use an alternate dbpath, specify the path in the configuration file (e.g. C:\Program Files\MongoDB\mongod.cfg) or on the command line with the --dbpath option.

   If the dbpath directory does not exist, mongod.exe will not start. The default value for dbpath is \data\db.

   If needed, you can install services for multiple instances of mongod.exe or mongos.exe. Install each service with a unique --serviceName and --serviceDisplayName. Use multiple instances only when sufficient system resources exist and your system design requires it.

3. Stop or remove the MongoDB service as needed.

   To stop the MongoDB service use the following command:

   net stop MongoDB
   

   To remove the MongoDB service use the following command:

   "C:\Program Files\MongoDB\bin\mongod.exe" --remove
   

Manually Create a Windows Service for MongoDB

The following procedure assumes you have installed MongoDB using the MSI installer, with the default path C:\Program Files\MongoDB 2.6 Standard.

If you have installed in an alternative directory, you will need to adjust the paths as appropriate.

1. Open an Administrator command prompt.

   Windows 7 / Vista / Server 2008 (and R2)

   Press Win + R, then type cmd, then press Ctrl + Shift + Enter.

   Windows 8

   Press Win + X, then press A.

   Execute the remaining steps from the Administrator command prompt.

2. Create directories.

   Create directories for your database and log files:

   mkdir c:\data\db
   mkdir c:\data\log
   

3. Create a configuration file.

   Create a configuration file. This file can include any of the configuration options for mongod, but must include a valid setting for logpath:

   The following creates a configuration file, specifying both the logpath and the dbpath settings in the configuration file:

   echo logpath=c:\data\log\mongod.log> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg"
   echo dbpath=c:\data\db>> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg"
   

4. Create the MongoDB service.

   Create the MongoDB service.

   sc.exe create MongoDB binPath= "\"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe\" --service --config=\"C:\Program Files\MongoDB 2.6 Standard\mongod.cfg\"" DisplayName= "MongoDB 2.6 Standard" start= "auto"
   

   sc.exe requires a space between “=” and the configuration values (eg “binPath=”), and a “” to escape double quotes.

   If successfully created, the following log message will display:

   [SC] CreateService SUCCESS
   

5. Start the MongoDB service.

   net start MongoDB
   

6. Stop or remove the MongoDB service as needed.

   To stop the MongoDB service, use the following command:

   net stop MongoDB
   

   To remove the MongoDB service, first stop the service and then run the following command:

   sc.exe delete MongoDB
   

Just to expand on the previous answer colorRampPalettecan handle more than two colors.

So for a more expanded "heat map" type look you can....

colfunc<-colorRampPalette(c("red","yellow","springgreen","royalblue"))
plot(rep(1,50),col=(colfunc(50)), pch=19,cex=2)

The resulting image:

I encountered

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from projects)

The cause was that I had not started the MySQL server.

It may help to check that the MySQL is running as the first step in troubleshooting the error.

On Scientific Linux 6 (similar to CentOS 6-- SL is now replaced by CentOS, AIUI), I had to use /usr/sbin/prelink -av -mR which I found suggested at https://stelfox.net/blog/2014/08/dependency-prelink-issues/

Until I did that, I got a cc1 error gcc: error trying to exec 'cc1': execvp: No such file or directory when I tried to compile, and gcc --version reported 4.2.2 instead of 4.4.7, despite that version being reported by yum.

It may or may not be related, but the system had run out of space on /var

No, it's not.

Attributes are meta-data and stored in binary-form in the compiled assembly (that's also why you can only use simple types in them).

I have a simple and generic hack to perform key/value if statement instead of boolean-only in mustache (and in an extremely readable fashion!) :

function buildOptions (object) {
    var validTypes = ['string', 'number', 'boolean'];
    var value;
    var key;
    for (key in object) {
        value = object[key];
        if (object.hasOwnProperty(key) && validTypes.indexOf(typeof value) !== -1) {
            object[key + '=' + value] = true;
        }
    }
    return object;
}

With this hack, an object like this:

var contact = {
  "id": 1364,
  "author_name": "Mr Nobody",
  "notified_type": "friendship",
  "action": "create"
};

Will look like this before transformation:

var contact = {
  "id": 1364,
  "id=1364": true,
  "author_name": "Mr Nobody",
  "author_name=Mr Nobody": true,
  "notified_type": "friendship",
  "notified_type=friendship": true,
  "action": "create",
  "action=create": true
};

And your mustache template will look like this:

{{#notified_type=friendship}}
    friendship…
{{/notified_type=friendship}}

{{#notified_type=invite}}
    invite…
{{/notified_type=invite}}

Also, It can be done with LINQ

var str = "Hello@Hello&Hello(Hello)";
var characters = str.Select(c => char.IsLetter(c) ? c : ',')).ToArray();             
var output = new string(characters);
Console.WriteLine(output);

It's only blank for you because you have not set the sql_mode. If you set it, then that query will show you the details:

mysql> SELECT @@sql_mode;
+------------+
| @@sql_mode |
+------------+
|            |
+------------+
1 row in set (0.00 sec)

mysql> set sql_mode=ORACLE;
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT @@sql_mode;
+----------------------------------------------------------------------------------------------------------------------+
| @@sql_mode                                                                                                           |
+----------------------------------------------------------------------------------------------------------------------+
| PIPES_AS_CONCAT,ANSI_QUOTES,IGNORE_SPACE,ORACLE,NO_KEY_OPTIONS,NO_TABLE_OPTIONS,NO_FIELD_OPTIONS,NO_AUTO_CREATE_USER |
+----------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

The solution for those who use composer is to use a volume pointing to the parent folder:

#docker-composer.yml

foo:
  build: foo
  volumes:
    - ./:/src/:ro

But I'm pretty sure the can be done playing with volumes in Dockerfile.

For starters, memory_get_peak_usage() will not be helpful here. It will only return the amount of memory which was allocated, and that is the same number which caused the error.

memory_get_usage will return the active amount of memory which is being allocated when it is called.

ini_set('memory_limit', '256M'); will set the maximum allowance of PHP's footprint on your systems Memory. If you are getting OOM at 768K, upping it will not fix the problem.

There is no indication as to what version of PHP you are using, but I would suggest an upgrade immediately. There are several bugs where Zend's Memory Manager fails to deallocate memory, which would lead you exactly to the same problem.

Are both your local server and your production server running the same version of OS, the same long bit and the same version of PHP? The answer will be no.

If it is unrelated to the windows malloc() issue, being it is a sub domain and probably within a VirtualHost, and allocating only 768k, it almost sounds like an OS issue.

Run tasklist from the command prompt when you access your script. Do you see an additional Apache thread, or Memory usage across the processes spike?

One last idea is, run flush() and/or ob_flush(); after each loop for the table row/column. This should clear your buffer and save you some memory in the event this is where the issue is occurring.

        echo "this is a file"                                                                             
else                                                                                                      
        echo "this is not a file"

You should check out OGX.List which has built in filtering methods and extends the standard javascript array (and also grouping, sorting and finding). Here's a list of operators it supports for the filters:

'eq' //Equal to
'eqjson' //For deep objects, JSON comparison, equal to
'neq' //Not equal to
'in' //Contains
'nin' //Doesn't contain
'lt' //Lesser than
'lte' //Lesser or equal to
'gt' //Greater than
'gte' //Greater or equal to
'btw' //Between, expects value to be array [_from_, _to_]
'substr' //Substring mode, equal to, expects value to be array [_from_, _to_, _niddle_]
'regex' //Regex match

You can use it this way

  let list = new OGX.List(your_array);
  list.addFilter('price', 'btw', 100, 500);
  list.addFilter('sqft', 'gte', 500);
  let filtered_list = list.filter();

Or even this way

  let list = new OGX.List(your_array);
  let filtered_list = list.get({price:{btw:[100,500]}, sqft:{gte:500}});

Or as a one liner

   let filtered_list = new OGX.List(your_array).get({price:{btw:[100,500]}, sqft:{gte:500}});

this is old but for help :

you can also use the stringReader stream

string str = "asasdkopaksdpoadks";
StringReader TheStream = new StringReader( str );

You need to turn off the compiler optimisation.

If you are interested in a particular variable in gdb, you can delare the variable as "volatile" and recompile the code. This will make the compiler turn off compiler optimization for that variable.

volatile int quantity = 0;

I'd just like to add something to this post for asp:button. I've tried clientId and it doesn't seem to work for me:

__doPostBack('<%= btn.ClientID%>', '');

However, getting the UniqueId seems to post back to the server, like below:

__doPostBack('<%= btn.UniqueID%>', '');

This might help someone else in future, hence posting this.

create your cell by xib or storyboard. give it's outlet's contents. now call it in CellForRowAtIndexPath. eg. if you want to set cell height according to Comment's label text.

so set you commentsLbl.numberOfLine=0;

so set you commentsLbl.numberOfLine=0;

then in ViewDidLoad

 self.table.estimatedRowHeight = 44.0 ;
self.table.rowHeight = UITableViewAutomaticDimension;

and now

-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return UITableViewAutomaticDimension;}

So I take it if the user enters 2, you want the output to be something like:

!!
!!
!!
!!

Correct?

To get that, you would need something like:

rows = 4
times_to_repeat = int(raw_input("How many times to repeat per row? ")

for i in range(rows):
    print "!" * times_to_repeat

That would result in:

How many times to repeat per row?
>> 4
!!!!
!!!!
!!!!
!!!!

I have not tested this, but it should run error free.

Chrome browser considers integer value as return type not boolean value so,

this.state.data.sort((a, b) => a.item.timeM > b.item.timeM ? 1:-1).map(
    (item, i) => <div key={i}> {item.matchID} {item.timeM} {item.description}</div>
)

pthread_exit terminates the calling thread while pthread_join suspends execution of calling thread until target threads completes execution.

They are pretty much well explained in detail in the open group documentation:

• pthread_exit
• pthread_join

You can use the non-standard FROM clause.

UPDATE b
SET column1 = a.column1,
  column2 = a.column2,
  column3 = a.column3
FROM a
WHERE a.id = b.id
AND b.id = 1

For background images, make sure to use url()

node.backgroundImage = 'url(' + e.target.result + ')';

Under the job workspace folder, like:

C:\Program Files (x86)\Jenkins\jobs\job_name

there is a file named nextBuildNumber.

Setting the build number in the file and reloading the configuration from disk (Manage Jenkins menu) will force the next build you start to have the value from the file as BUILD_NUMBER.

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

JSFIDDLE

Given an object which I suspect to be some kind of IList<>, how can I determine of what it's an IList<>?

Here's the gutsy solution. It assumes you have the actual object to test (rather than a Type).

public static Type ListOfWhat(Object list)
{
    return ListOfWhat2((dynamic)list);
}

private static Type ListOfWhat2<T>(IList<T> list)
{
    return typeof(T);
}

Example usage:

object value = new ObservableCollection<DateTime>();
ListOfWhat(value).Dump();

Prints

typeof(DateTime)

Just a note of a peculiarity I faced:
Consider:

db server:  192.168.0.101
web server: 192.168.0.102

If you have a user defined in mysql.user as 'user'@'192.168.0.102' with password1 and another 'user'@'192.168.0.%' with password2,

then,

if you try to connect to the db server from the web server as 'user' with password2,

it will result in an 'Access denied' error because the single IP 'user'@'192.168.0.102' authentication is used over the wildcard 'user'@'192.168.0.%' authentication.

Try:

printf "%X\n" ${MY_NUMBER}

Hello this is a snippet from an old project of mine that uses curl to get ip information from some free ip databases services which reply in json format. I think it might help you.

$ip_srv = array("http://freegeoip.net/json/$this->ip","http://smart-ip.net/geoip-json/$this->ip");

getUserLocation($ip_srv);

Function:

function getUserLocation($services) {

        $ctx = stream_context_create(array('http' => array('timeout' => 15))); // 15 seconds timeout

        for ($i = 0; $i < count($services); $i++) {

            // Configuring curl options
            $options = array (
                CURLOPT_RETURNTRANSFER => true, // return web page
                //CURLOPT_HEADER => false, // don't return headers
                CURLOPT_HTTPHEADER => array('Content-type: application/json'),
                CURLOPT_FOLLOWLOCATION => true, // follow redirects
                CURLOPT_ENCODING => "", // handle compressed
                CURLOPT_USERAGENT => "test", // who am i
                CURLOPT_AUTOREFERER => true, // set referer on redirect
                CURLOPT_CONNECTTIMEOUT => 5, // timeout on connect
                CURLOPT_TIMEOUT => 5, // timeout on response
                CURLOPT_MAXREDIRS => 10 // stop after 10 redirects
            ); 

            // Initializing curl
            $ch = curl_init($services[$i]);
            curl_setopt_array ( $ch, $options );

            $content = curl_exec ( $ch );
            $err = curl_errno ( $ch );
            $errmsg = curl_error ( $ch );
            $header = curl_getinfo ( $ch );
            $httpCode = curl_getinfo ( $ch, CURLINFO_HTTP_CODE );

            curl_close ( $ch );

            //echo 'service: ' . $services[$i] . '</br>';
            //echo 'err: '.$err.'</br>';
            //echo 'errmsg: '.$errmsg.'</br>';
            //echo 'httpCode: '.$httpCode.'</br>';
            //print_r($header);
            //print_r(json_decode($content, true));

            if ($err == 0 && $httpCode == 200 && $header['download_content_length'] > 0) {

                return json_decode($content, true);

            } 

        }
    }

If you're doing programatic customisation, don't hard code the system font. Use UIFont systemFontOfSize:, UIFont boldSystemFontOfSize: and UIFont italicSystemFontOfSize (Apple documentation).

This has become especially relevant since iOS 7, which changed the system font to Helvetica Neue.

This has become super especially relevant since iOS 9, which changed the system font again to San Francisco.

From Asp.net core 2.2 to above you can code as below:

Step 1. Create an AppSettings class file.

This file contains some methods to help get value by key from the appsettings.json file. Look like as code below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace ReadConfig.Bsl
{
  public class AppSettings
  {
      private static AppSettings _instance;
      private static readonly object ObjLocked = new object();
      private IConfiguration _configuration;

      protected AppSettings()
      {
      }

      public void SetConfiguration(IConfiguration configuration)
      {
          _configuration = configuration;
      }

      public static AppSettings Instance
      {
          get
          {
              if (null == _instance)
              {
                  lock (ObjLocked)
                  {
                      if (null == _instance)
                          _instance = new AppSettings();
                  }
              }
              return _instance;
          }
      }

      public string GetConnection(string key, string defaultValue = "")
      {
          try
          {
              return _configuration.GetConnectionString(key);
          }
          catch
          {
              return defaultValue;
          }
      }

      public T Get<T>(string key = null)
      {
          if (string.IsNullOrWhiteSpace(key))
              return _configuration.Get<T>();
          else
              return _configuration.GetSection(key).Get<T>();
      }

      public T Get<T>(string key, T defaultValue)
      {
          if (_configuration.GetSection(key) == null)
              return defaultValue;

          if (string.IsNullOrWhiteSpace(key))
              return _configuration.Get<T>();
          else
              return _configuration.GetSection(key).Get<T>();
      }

      public static T GetObject<T>(string key = null)
      {
          if (string.IsNullOrWhiteSpace(key))
              return Instance._configuration.Get<T>();
          else
          {
              var section = Instance._configuration.GetSection(key);
              return section.Get<T>();
          }
      }

      public static T GetObject<T>(string key, T defaultValue)
      {
          if (Instance._configuration.GetSection(key) == null)
              return defaultValue;

          if (string.IsNullOrWhiteSpace(key))
              return Instance._configuration.Get<T>();
          else
              return Instance._configuration.GetSection(key).Get<T>();
      }
  }
}

Step 2. Initial configuration for AppSettings object

We need to declare and load appsettings.json file when the application starts, and load configuration information for AppSettings object. We will do this work in the constructor of the Startup.cs file. Please notice line AppSettings.Instance.SetConfiguration(Configuration);

public Startup(IHostingEnvironment evm)
{
    var builder = new ConfigurationBuilder()
      .SetBasePath(evm.ContentRootPath)
      .AddJsonFile("appsettings.json", true, true)
      .AddJsonFile($"appsettings.{evm.EnvironmentName}.json", true)
      .AddEnvironmentVariables();
    Configuration = builder.Build(); // load all file config to Configuration property 
    AppSettings.Instance.SetConfiguration(Configuration);       
}

Okay, now I have an appsettings.json file with some keys as below:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "ConnectionString": "Data Source=localhost;Initial Catalog=ReadConfig;Persist Security Info=True;User ID=sa;Password=12345;"
  },
  "MailConfig": {
    "Servers": {
      "MailGun": {
        "Pass": "65-1B-C9-B9-27-00",
        "Port": "587",
        "Host": "smtp.gmail.com"
      }
    },
    "Sender": {
      "Email": "[email protected]",
      "Pass": "123456"
    }
  }
}

Step 3. Read config value from an action

I make demo an action in Home controller as below :

public class HomeController : Controller
{
    public IActionResult Index()
    {
        var connectionString = AppSettings.Instance.GetConnection("ConnectionString");
        var emailSender = AppSettings.Instance.Get<string>("MailConfig:Sender:Email");
        var emailHost = AppSettings.Instance.Get<string>("MailConfig:Servers:MailGun:Host");

        string returnText = " 1. Connection String \n";
        returnText += "  " +connectionString;
        returnText += "\n 2. Email info";
        returnText += "\n Sender : " + emailSender;
        returnText += "\n Host : " + emailHost;

        return Content(returnText);
    }
}

And below is the result:

For more information, you can refer article get value from appsettings.json in asp.net core for more detail code.

TemplateBinding is not quite the same thing. MSDN docs are often written by people that have to quiz monosyllabic SDEs about software features, so the nuances are not quite right.

TemplateBindings are evaluated at compile time against the type specified in the control template. This allows for much faster instantiation of compiled templates. Just fumble the name in a templatebinding and you'll see that the compiler will flag it.

The binding markup is resolved at runtime. While slower to execute, the binding will resolve property names that are not visible on the type declared by the template. By slower, I'll point out that its kind of relative since the binding operation takes very little of the application's cpu. If you were blasting control templates around at high speed you might notice it.

As a matter of practice use the TemplateBinding when you can but don't fear the Binding.

public static IEnumerable<string> GetData()
{
    yield return "1";
    yield return "2";
    yield return "3";
}

IEnumerable<string> m_oEnum = GetData();

You'll see people using the Timer class to do this. Unfortunately, it isn't always accurate. Your best bet is to get the system time when the user enters input, calculate a target system time, and check if the system time has exceeded the target system time. If it has, then break out of the loop.

When your activity is recreated after it was previously destroyed, you can recover your saved state from the Bundle that the system passes your activity. Both the onCreate() and onRestoreInstanceState() callback methods receive the same Bundle that contains the instance state information.

Because the onCreate() method is called whether the system is creating a new instance of your activity or recreating a previous one, you must check whether the state Bundle is null before you attempt to read it. If it is null, then the system is creating a new instance of the activity, instead of restoring a previous one that was destroyed.

static final String STATE_USER = "user";
private String mUser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Check whether we're recreating a previously destroyed instance
    if (savedInstanceState != null) {
        // Restore value of members from saved state
        mUser = savedInstanceState.getString(STATE_USER);
    } else {
        // Probably initialize members with default values for a new instance
        mUser = "NewUser";
    }
}

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putString(STATE_USER, mUser);
    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

http://developer.android.com/training/basics/activity-lifecycle/recreating.html

can also Use parameterized each with index and the element.

$('#selectIntegrationConf').find('option').each(function(index,element){
 console.log(index);
 console.log(element.value);
 console.log(element.text);
 });

// this will also work

$('#selectIntegrationConf option').each(function(index,element){
 console.log(index);
 console.log(element.value);
 console.log(element.text);
 });

Java 5 provides this more compact syntax:

static final Map<String , String> FLAVORS = new HashMap<String , String>() {{
    put("Up",    "Down");
    put("Charm", "Strange");
    put("Top",   "Bottom");
}};

Using simple html,

 <div> 
    <object type="text/html" data="http://validator.w3.org/" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">
    </object>
 </div>

Or jquery,

<script>
        $("#mydiv")
            .html('<object data="http://your-website-domain"/>');
</script>

The difference between constructor and getInitialState is the difference between ES6 and ES5 itself.
getInitialState is used with React.createClass and
constructor is used with React.Component.

Hence the question boils down to advantages/disadvantages of using ES6 or ES5.

Let's look at the difference in code

ES5

var TodoApp = React.createClass({ 
  propTypes: {
    title: PropTypes.string.isRequired
  },
  getInitialState () { 
    return {
      items: []
    }; 
  }
});

ES6

class TodoApp extends React.Component {
  constructor () {
    super()
    this.state = {
      items: []
    }
  }
};

There is an interesting reddit thread regarding this.

React community is moving closer to ES6. Also it is considered as the best practice.

There are some differences between React.createClass and React.Component. For instance, how this is handled in these cases. Read more about such differences in this blogpost and facebook's content on autobinding

constructor can also be used to handle such situations. To bind methods to a component instance, it can be pre-bonded in the constructor. This is a good material to do such cool stuff.

Some more good material on best practices
Best Practices for Component State in React.js
Converting React project from ES5 to ES6

Update: April 9, 2019,:

With the new changes in Javascript class API, you don't need a constructor.

You could do

class TodoApp extends React.Component {

    this.state = {items: []}
};

This will still get transpiled to constructor format, but you won't have to worry about it. you can use this format that is more readable.

With React Hooks

From React version 16.8, there's a new API Called hooks.

Now, you don't even need a class component to have a state. It can even be done in a functional component.

import React, { useState } from 'react';

function TodoApp () {
  const items = useState([]);

Note that the initial state is passed as an argument to useState; useState([])

After reading some issues reported on the GitHub repository, I found the solution.

In order to update the angular-cli package installed globally in your system, you need to run:

npm uninstall -g @angular-cli
npm install -g @angular/cli@latest

Depending on your system, you may need to prefix the above commands with sudo.

Also, most likely you want to also update your local project version, because inside your project directory it will be selected with higher priority than the global one:

rm -rf node_modules
npm uninstall --save-dev @angular-cli
npm install --save-dev @angular/cli@latest
npm install

thanks grizzm0 for pointing this out on GitHub.

After updating your CLI, you probably want to update your Angular version too.

Note: if you are updating to Angular CLI 6+ from an older version, you might need to read this.

Edit: In addition, if you were still on a 1.x version of the cli, you need to convert your angular-cli.json to angular.json, which you can do with the following command:

ng update @angular/cli --from=1.7.4 --migrate-only

(check this for more details).

For loading animated gifs stored in a source package (in the source code), this worked for me:

URL url = MyClass.class.getResource("/res/images/animated.gif");
ImageIcon imageIcon = new ImageIcon(url);
JLabel label = new JLabel(imageIcon);

  var json = {"ListID" : "1", "ItemName":"test"};
    $.ajax({
            url: url,
            type: 'POST',        
            data: username, 
            cache:false,
            beforeSend: function(xhr) {  
                xhr.setRequestHeader("Accept", "application/json");  
                xhr.setRequestHeader("Content-Type", "application/json");  
            },       
            success:function(response){
             console.log("Success")
            },
              error : function(xhr, status, error) {
            console.log("error")
            }
);

If your DBMS doesn't support distinct with multiple columns like this:

select distinct(col1, col2) from table

Multi select in general can be executed safely as follows:

select distinct * from (select col1, col2 from table ) as x

As this can work on most of the DBMS and this is expected to be faster than group by solution as you are avoiding the grouping functionality.

The center class must have a width in order to make auto margin work:

.center { margin: 0 auto; width: 400px; }

Then I would apply the center class to the video itself, not a container:

<video class='center' …>…</video>

In MS Windows, the mongoimport command has to be run in a normal Windows command prompt, not from the mongodb command prompt.

Either directly in form parameters or

string controlName = this.Request.Params.Get("__EVENTTARGET");

Edit: To check if a control caused a postback (manually):

// input Image with name="imageName"
if (this.Request["imageName"+".x"] != null) ...;//caused postBack

// Other input with name="name"
if (this.Request["name"] != null) ...;//caused postBack

You could also iterate through all the controls and check if one of them caused a postBack using the above code.

Python, being a byte-code-compiled interpreted language, is very difficult to lock down. Even if you use a exe-packager like py2exe, the layout of the executable is well-known, and the Python byte-codes are well understood.

Usually in cases like this, you have to make a tradeoff. How important is it really to protect the code? Are there real secrets in there (such as a key for symmetric encryption of bank transfers), or are you just being paranoid? Choose the language that lets you develop the best product quickest, and be realistic about how valuable your novel ideas are.

If you decide you really need to enforce the license check securely, write it as a small C extension so that the license check code can be extra-hard (but not impossible!) to reverse engineer, and leave the bulk of your code in Python.

From http://api.jquery.com/jQuery/

Selector Context By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function. For example, to do a search within an event handler, the search can be restricted like so:

$( "div.foo" ).click(function() { 
   $( "span", this ).addClass( "bar" );
});

When the search for the span selector is restricted to the context of this, only spans within the clicked element will get the additional class.

So for your example I would suggest something like:

$("div", ".container").each(function(){
     //do whatever
 });

Properties are used to encapsulate some data. You could use a plain field:

public string MyField

But this field can be accessed by all outside users of your class. People can insert illegal values or change the value in ways you didn't expect.

By using a property, you can encapsulate the way your data is accessed. C# has a nice syntax for turning a field into a property:

string MyProperty { get; set; }

This is called an auto-implemented property. When the need arises you can expand your property to:

string _myProperty;

public string MyProperty
{
    get { return _myProperty; }
    set { _myProperty = value; }
}

Now you can add code that validates the value in your setter:

set
{
    if (string.IsNullOrWhiteSpace(value))
        throw new ArgumentNullException();

    _myProperty = value;
}

Properties can also have different accessors for the getter and the setter:

public string MyProperty { get; private set; }

This way you create a property that can be read by everyone but can only be modified by the class itself.

You can also add a completely custom implementation for your getter:

public string MyProperty
{
    get
    {
        return DateTime.Now.Second.ToString();
    }
}

When C# compiles your auto-implemented property, it generates Intermediate Language (IL). In your IL you will see a get_MyProperty and set_MyProperty method. It also creates a backing field called <MyProperty>k_BackingField (normally this would be an illegal name in C# but in IL it's valid. This way you won't get any conflicts between generated types and your own code). However, you should use the official property syntax in C#. This creates a nicer experience in C# (for example with IntelliSense).

By convention, you shouldn't use properties for operations that take a long time.

From How to get full date with correct format?:

Please, use

android.text.format.DateFormat.getDateFormat(Context context)
android.text.format.DateFormat.getTimeFormat(Context context)

to get valid time and date formats in sense of current user settings (12/24 time format, for example).

import android.text.format.DateFormat;

private void some() {
    final Calendar t = Calendar.getInstance();
    textView.setText(DateFormat.getTimeFormat(this/*Context*/).format(t.getTime()));
}

use this code (in console mode):

Gem::Specification.all_names

Just to save time of people who come to the post (like me, who looking for Spring config type and want you schema name be set by an external source (property file)). The configuration will work for you is

<bean id="domainEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="JiraManager"/>
    <property name="dataSource" ref="domainDataSource"/>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="generateDdl" value="false"/>
            <property name="showSql" value="false"/>
            <property name="databasePlatform" value="${hibernate.dialect}"/>
        </bean>
    </property>
    <property name="jpaProperties">
       <props>
            <prop key="hibernate.hbm2ddl.auto">none</prop>
            <prop key="hibernate.default_schema">${yourSchema}</prop>
       </props>
</property>

</bean>

Ps : For the hibernate.hdm2ddl.auto, you could look in the post Hibernate hbm2ddl.auto possible values and what they do? I have used to set create-update,because it is convenient. However, in production, I think it is better to take control of the ddl, so I take whatever ddl generate first time, save it, rather than let it automatically create and update.

Backspace and tab both move the cursor position. Neither is truly a 'printable' character.

Your code says:

1. print "foo"
2. move the cursor back one space
3. move the cursor forward to the next tabstop
4. output "bar".

To get the output you expect, you need printf("foo\b \tbar"). Note the extra 'space'. That says:

1. output "foo"
2. move the cursor back one space
3. output a ' ' (this replaces the second 'o').
4. move the cursor forward to the next tabstop
5. output "bar".

Most of the time it is inappropriate to use tabs and backspace for formatting your program output. Learn to use printf() formatting specifiers. Rendering of tabs can vary drastically depending on how the output is viewed.

This little script shows one way to alter your terminal's tab rendering. Tested on Ubuntu + gnome-terminal:

#!/bin/bash
tabs -8 
echo -e "\tnormal tabstop"
for x in `seq 2 10`; do
  tabs $x
  echo -e "\ttabstop=$x"
 done

tabs -8
echo -e "\tnormal tabstop"

Also see man setterm and regtabs.

And if you redirect your output or just write to a file, tabs will quite commonly be displayed as fewer than the standard 8 chars, especially in "programming" editors and IDEs.

So in otherwords:

printf("%-8s%s", "foo", "bar"); /* this will ALWAYS output "foo     bar" */
printf("foo\tbar"); /* who knows how this will be rendered */

IMHO, tabs in general are rarely appropriate for anything. An exception might be generating output for a program that requires tab-separated-value input files (similar to comma separated value).

Backspace '\b' is a different story... it should never be used to create a text file since it will just make a text editor spit out garbage. But it does have many applications in writing interactive command line programs that cannot be accomplished with format strings alone. If you find yourself needing it a lot, check out "ncurses", which gives you much better control over where your output goes on the terminal screen. And typically, since it's 2011 and not 1995, a GUI is usually easier to deal with for highly interactive programs. But again, there are exceptions. Like writing a telnet server or console for a new scripting language.

In case anyone are still interested in this subject, I find that the best approach for filtering lists is to create a generic Filter class and use it with some base reflection/generics techniques contained in the Java old school SDK package. Here's what I did:

public class GenericListFilter<T> extends Filter {

    /**
     * Copycat constructor
     * @param list  the original list to be used
     */
    public GenericListFilter (List<T> list, String reflectMethodName, ArrayAdapter<T> adapter) {
        super ();

        mInternalList = new ArrayList<>(list);
        mAdapterUsed  = adapter;

        try {
            ParameterizedType stringListType = (ParameterizedType)
                    getClass().getField("mInternalList").getGenericType();
            mCompairMethod =
                    stringListType.getActualTypeArguments()[0].getClass().getMethod(reflectMethodName);
        }
        catch (Exception ex) {
            Log.w("GenericListFilter", ex.getMessage(), ex);

            try {
                if (mInternalList.size() > 0) {
                    T type = mInternalList.get(0);
                    mCompairMethod = type.getClass().getMethod(reflectMethodName);
                }
            }
            catch (Exception e) {
                Log.e("GenericListFilter", e.getMessage(), e);
            }

        }
    }

    /**
     * Let's filter the data with the given constraint
     * @param constraint
     * @return
     */
    @Override protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();
        List<T> filteredContents = new ArrayList<>();

        if ( constraint.length() > 0 ) {
            try {
                for (T obj : mInternalList) {
                    String result = (String) mCompairMethod.invoke(obj);
                    if (result.toLowerCase().startsWith(constraint.toString().toLowerCase())) {
                        filteredContents.add(obj);
                    }
                }
            }
            catch (Exception ex) {
                Log.e("GenericListFilter", ex.getMessage(), ex);
            }
        }
        else {
            filteredContents.addAll(mInternalList);
        }

        results.values = filteredContents;
        results.count  = filteredContents.size();
        return results;
    }

    /**
     * Publish the filtering adapter list
     * @param constraint
     * @param results
     */
    @Override protected void publishResults(CharSequence constraint, FilterResults results) {
        mAdapterUsed.clear();
        mAdapterUsed.addAll((List<T>) results.values);

        if ( results.count == 0 ) {
            mAdapterUsed.notifyDataSetInvalidated();
        }
        else {
            mAdapterUsed.notifyDataSetChanged();
        }
    }

    // class properties
    private ArrayAdapter<T> mAdapterUsed;
    private List<T> mInternalList;
    private Method  mCompairMethod;
}

And afterwards, the only thing you need to do is to create the filter as a member class (possibly within the View's "onCreate") passing your adapter reference, your list, and the method to be called for filtering:

this.mFilter = new GenericFilter<MyObjectBean> (list, "getName", adapter);

The only thing missing now, is to override the "getFilter" method in the adapter class:

@Override public Filter getFilter () {
     return MyViewClass.this.mFilter;
}

All done! You should successfully filter your list - Of course, you should also implement your filter algorithm the best way that describes your need, the code bellow is just an example.. Hope it helped, take care.

You need to attach a click event handler and clear the contents of the textarea from that handler.

HTML

<input type="button" value="Clear" id="clear"> 
<textarea id='output' rows=20 cols=90></textarea>

JS

var input = document.querySelector('#clear');
var textarea = document.querySelector('#output');

input.addEventListener('click', function () {
    textarea.value = '';
}, false);

and here's the working demo.

If the other answers mentioned do not work for you, try deleting your pip cache and reinstalling the package. My machine runs Ubuntu14.04 and it was located under ~/.cache/pip. Deleting this folder did the trick for me.

Try this

import datetime
import time
start_time = datetime.datetime.now().time().strftime('%H:%M:%S')
time.sleep(5)
end_time = datetime.datetime.now().time().strftime('%H:%M:%S')
total_time=(datetime.datetime.strptime(end_time,'%H:%M:%S') - datetime.datetime.strptime(start_time,'%H:%M:%S'))
print total_time

OUTPUT :

0:00:05

Finally below works for me

$("#priceSlider").slider('option',{min: 5, max: 20,value:[6,19]}); $("#priceSlider").slider("refresh");

You must specify a delimiter for your expression. A delimiter is a special character used at the start and end of your expression to denote which part is the expression. This allows you to use modifiers and the interpreter to know which is an expression and which are modifiers. As the error message states, the delimiter cannot be a backslash because the backslash is the escape character.

$pattern = "/My name is '(.*)' and im fine/";

and below the same example but with the i modifier to match without being case sensitive.

$pattern = "/My name is '(.*)' and im fine/i";

As you can see, the i is outside of the slashes and therefore is interpreted as a modifier.

Also bear in mind that if you use a forward slash character (/) as a delimiter you must then escape further uses of / in the regular expression, if present.

I think this is a more functional way to do it. Dan's answer do not work in a recursive context.

This function solves the problem when your element is inside others scrollable divs by testing any levels recursively up to the HTML tag, and stops at the first false.

/**
 * fullVisible=true only returns true if the all object rect is visible
 */
function isReallyVisible(el, fullVisible) {
    if ( el.tagName == "HTML" )
            return true;
    var parentRect=el.parentNode.getBoundingClientRect();
    var rect = arguments[2] || el.getBoundingClientRect();
    return (
            ( fullVisible ? rect.top    >= parentRect.top    : rect.bottom > parentRect.top ) &&
            ( fullVisible ? rect.left   >= parentRect.left   : rect.right  > parentRect.left ) &&
            ( fullVisible ? rect.bottom <= parentRect.bottom : rect.top    < parentRect.bottom ) &&
            ( fullVisible ? rect.right  <= parentRect.right  : rect.left   < parentRect.right ) &&
            isReallyVisible(el.parentNode, fullVisible, rect)
    );
};

Thanks so much Jason Pan for suggesting that method. The thread1 if statement is not atomic, so that while that statement executes, it's possible for thread2 to intrude on thread1, allowing non-reachable code to be reached. I've organized ideas from the prior posts into a complete demonstration program (below) that I ran with Python 2.7.

With some thoughtful analysis I'm sure we could gain further insight, but for now I think it's important to demonstrate what happens when non-atomic behavior meets threading.

# ThreadTest01.py - Demonstrates that if non-atomic actions on
# global variables are protected, task can intrude on each other.
from threading import Thread
import time

# global variable
a = 0; NN = 100

def thread1(threadname):
    while True:
      if a % 2 and not a % 2:
          print("unreachable.")
    # end of thread1

def thread2(threadname):
    global a
    for _ in range(NN):
        a += 1
        time.sleep(0.1)
    # end of thread2

thread1 = Thread(target=thread1, args=("Thread1",))
thread2 = Thread(target=thread2, args=("Thread2",))

thread1.start()
thread2.start()

thread2.join()
# end of ThreadTest01.py

As predicted, in running the example, the "unreachable" code sometimes is actually reached, producing output.

Just to add, when I inserted a lock acquire/release pair into thread1 I found that the probability of having the "unreachable" message print was greatly reduced. To see the message I reduced the sleep time to 0.01 sec and increased NN to 1000.

With a lock acquire/release pair in thread1 I didn't expect to see the message at all, but it's there. After I inserted a lock acquire/release pair also into thread2, the message no longer appeared. In hind signt, the increment statement in thread2 probably also is non-atomic.

If You Are Able to Edit the Offending Stylesheet

If the user-agent stylesheet's style is causing problems for the browser it's supposed to fix, then you could try removing the offending style and testing that to ensure it doesn't have any unexpected adverse effects elsewhere.

If it doesn't, use the modified stylesheet. Fixing browser quirks is what these sheets are for - they fix issues, they aren't supposed to introduce new ones.

If You Are Not Able to Edit the Offending Stylesheet

If you're unable to edit the stylesheet that contains the offending line, you may consider using the !important keyword.

An example:

.override {
    border: 1px solid #000 !important;
}

.a_class {
    border: 2px solid red;
}

And the HTML:

<p class="a_class">content will have 2px red border</p>
<p class="override a_class">content will have 1px black border</p>

Live example

Try to use !important only where you really have to - if you can reorganize your styles such that you don't need it, this would be preferable.

In Intellij, go to View -> Tool Windows -> choose Maven Projects. On the Lifecyle dropdown, right-click on package -> choose Create 'your-project [package]'...

Enter this value: package -Dmaven.test.skip=true -f pom.xml in the Command line field. Click Apply and a Run Configurations dropdown menu should appear along with your created custom maven command.

If you give the code a .c extension the compiler thinks it is C code, not C++. And the C++ compiler driver is called g++, if you use the gcc driver you will have linker problems, as the standard C++ libraries will not be linked by default. So you want:

g++ myprog.cpp

And do not even consider using an uppercase .C extension, unless you never want to port your code, and are prepared to be hated by those you work with.

See Function Definitions in the Language Reference.

If the form *identifier is present, it is initialized to a tuple receiving any excess positional parameters, defaulting to the empty tuple. If the form **identifier is present, it is initialized to a new dictionary receiving any excess keyword arguments, defaulting to a new empty dictionary.

Also, see Function Calls.

Assuming that one knows what positional and keyword arguments are, here are some examples:

Example 1:

# Excess keyword argument (python 2) example:
def foo(a, b, c, **args):
    print "a = %s" % (a,)
    print "b = %s" % (b,)
    print "c = %s" % (c,)
    print args

foo(a="testa", d="excess", c="testc", b="testb", k="another_excess")

As you can see in the above example, we only have parameters a, b, c in the signature of the foo function. Since d and k are not present, they are put into the args dictionary. The output of the program is:

a = testa
b = testb
c = testc
{'k': 'another_excess', 'd': 'excess'}

Example 2:

# Excess positional argument (python 2) example:
def foo(a, b, c, *args):
    print "a = %s" % (a,)
    print "b = %s" % (b,)
    print "c = %s" % (c,)
    print args

foo("testa", "testb", "testc", "excess", "another_excess")

Here, since we're testing positional arguments, the excess ones have to be on the end, and *args packs them into a tuple, so the output of this program is:

a = testa
b = testb
c = testc
('excess', 'another_excess')

You can also unpack a dictionary or a tuple into arguments of a function:

def foo(a,b,c,**args):
    print "a=%s" % (a,)
    print "b=%s" % (b,)
    print "c=%s" % (c,)
    print "args=%s" % (args,)

argdict = dict(a="testa", b="testb", c="testc", excessarg="string")
foo(**argdict)

Prints:

a=testa
b=testb
c=testc
args={'excessarg': 'string'}

And

def foo(a,b,c,*args):
    print "a=%s" % (a,)
    print "b=%s" % (b,)
    print "c=%s" % (c,)
    print "args=%s" % (args,)

argtuple = ("testa","testb","testc","excess")
foo(*argtuple)

Prints:

a=testa
b=testb
c=testc
args=('excess',)

What you could do is create a new class, similar to @Gregoire's example, however, you would want to override the ToString() method so it appears correctly in the combo box e.g.

public class Language
{
    private string _name;
    private string _code;

    public Language(string name, string code)
    {
        _name = name;
        _code = code;
    }

    public string Name { get { return _name; }  }
    public string Code { get { return _code; } }
    public override void ToString()
    {
        return _name;
    }
}

PHP parser will search your entire code for <?php (or <? if short_open_tag = On), so HTML comment tags have no effect on PHP parser behavior & if you don't want to parse your PHP code, you have to use PHP commenting directives(/* */ or //).

In my case I was adding javascript dynamicly and using double quotes 2 times in string templates so i changed the second to single quotes and the error was gone. I hope it will help some of the people coming here for the same reason.

This solved my issue (put it inside your create_app() function):

celery.conf.update(app.config)

class ContextTask(celery.Task):
    def __call__(self, *args, **kwargs):
        with app.app_context():
            return self.run(*args, **kwargs)

celery.Task = ContextTask

There are two ways:

1. To view the SQL that will be generated, simply call ToTraceString(). You can add it into your watch window and set a breakpoint to see what the query would be at any given point for any LINQ query.
2. You can attach a tracer to your SQL server of choice, which will show you the final query in all its gory detail. In the case of MySQL, the easiest way to trace the queries is simply to tail the query log with tail -f. You can learn more about MySQL's logging facilities in the official documentation. For SQL Server, the easiest way is to use the included SQL Server profiler.

It is not possible to return an array from a C++ function. 8.3.5[dcl.fct]/6:

Functions shall not have a return type of type array or function[...]

Most commonly chosen alternatives are to return a value of class type where that class contains an array, e.g.

struct ArrayHolder
{
    int array[10];
};

ArrayHolder test();

Or to return a pointer to the first element of a statically or dynamically allocated array, the documentation must indicate to the user whether he needs to (and if so how he should) deallocate the array that the returned pointer points to.

E.g.

int* test2()
{
    return new int[10];
}

int* test3()
{
    static int array[10];
    return array;
}

While it is possible to return a reference or a pointer to an array, it's exceedingly rare as it is a more complex syntax with no practical advantage over any of the above methods.

int (&test4())[10]
{
        static int array[10];
        return array;
}

int (*test5())[10]
{
        static int array[10];
        return &array;
}

In the spring framework, there is an annotation called the repository, and in the description of this annotation, there is useful information about the repository, which I think it is useful for this discussion.

Indicates that an annotated class is a "Repository", originally defined by Domain-Driven Design (Evans, 2003) as "a mechanism for encapsulating storage, retrieval, and search behavior which emulates a collection of objects".

Teams implementing traditional Java EE patterns such as "Data Access Object" may also apply this stereotype to DAO classes, though care should be taken to understand the distinction between Data Access Object and DDD-style repositories before doing so. This annotation is a general-purpose stereotype and individual teams may narrow their semantics and use as appropriate.

A class thus annotated is eligible for Spring DataAccessException translation when used in conjunction with a PersistenceExceptionTranslationPostProcessor. The annotated class is also clarified as to its role in the overall application architecture for the purpose of tooling, aspects, etc.

Just in case, here is what I did to get partial arguments, kind of. I’ve created a little helper that takes a partial name and a hash of parameters that will be passed to the partial:

Handlebars.registerHelper('render', function(partialId, options) {
  var selector = 'script[type="text/x-handlebars-template"]#' + partialId,
      source = $(selector).html(),
      html = Handlebars.compile(source)(options.hash);

  return new Handlebars.SafeString(html);
});

The key thing here is that Handlebars helpers accept a Ruby-like hash of arguments. In the helper code they come as part of the function’s last argument—options— in its hash member. This way you can receive the first argument—the partial name—and get the data after that.

Then, you probably want to return a Handlebars.SafeString from the helper or use “triple-stash”—{{{— to prevent it from double escaping.

Here is a more or less complete usage scenario:

<script id="text-field" type="text/x-handlebars-template">
  <label for="{{id}}">{{label}}</label>
  <input type="text" id="{{id}}"/>
</script>

<script id="checkbox-field" type="text/x-handlebars-template">
  <label for="{{id}}">{{label}}</label>
  <input type="checkbox" id="{{id}}"/>
</script>

(1) Is it possible to pass a JSON object to the url like in Ex.2?

No, because http://localhost:8080/api/v1/mno/objectKey/{"id":1, "name":"Saif"} is not a valid URL.

If you want to do it the RESTful way, use http://localhost:8080/api/v1/mno/objectKey/1/Saif, and defined your method like this:

@RequestMapping(path = "/mno/objectKey/{id}/{name}", method = RequestMethod.GET)
public Book getBook(@PathVariable int id, @PathVariable String name) {
    // code here
}

(2) How can we pass and parse the parameters in Ex.1?

Just add two request parameters, and give the correct path.

@RequestMapping(path = "/mno/objectKey", method = RequestMethod.GET)
public Book getBook(@RequestParam int id, @RequestParam String name) {
    // code here
}

UPDATE (from comment)

What if we have a complicated parameter structure ?

"A": [ {
    "B": 37181,
    "timestamp": 1160100436,
    "categories": [ {
        "categoryID": 2653,
        "timestamp": 1158555774
    }, {
        "categoryID": 4453,
        "timestamp": 1158555774
    } ]
} ]

Send that as a POST with the JSON data in the request body, not in the URL, and specify a content type of application/json.

@RequestMapping(path = "/mno/objectKey", method = RequestMethod.POST, consumes = "application/json")
public Book getBook(@RequestBody ObjectKey objectKey) {
    // code here
}

A little helper for all of you that have more than one Info.plist file...

find . -name Info.plist | xargs -I {} /usr/libexec/PlistBuddy -c 'Add NSLocationWhenInUseUsageDescription string' {} 

It will add the needed tag to all of the Info.plist files in the current directory (and subfolders).

Another is:

find . -name Info.plist | xargs -I {} /usr/libexec/PlistBuddy -c 'Set NSLocationWhenInUseUsageDescription $YOURDESCRIPTION' {} 

It will add your description to all files.

The base of NGLG answer https://stackoverflow.com/a/8811242/6619626 you can use the following function:

type
OurArrayStr=array of string;

function SplitString(DelimeterChars:char;Str:string):OurArrayStr;
var
seg: TStringList;
i:integer;
ret:OurArrayStr;
begin
    seg := TStringList.Create;
    ExtractStrings([DelimeterChars],[], PChar(Str), seg);
    for i:=0 to seg.Count-1 do
    begin
         SetLength(ret,length(ret)+1);
         ret[length(ret)-1]:=seg.Strings[i];
    end;
    SplitString:=ret;
    seg.Free;
end;

It works in all Delphi versions.

Can't you implement your own timeout system?

Keep a sorted list, or better yet a priority heap as Heath suggests, of timeout events. In your select or poll calls use the timeout value from the top of the timeout list. When that timeout arrives, do that action attached to that timeout.

That action could be closing a socket that hasn't connected yet.

While routing is indeed a good solution for application-level URL parsing, you may want to use the more low-level $location service, as injected in your own service or controller:

var paramValue = $location.search().myParam; 

This simple syntax will work for http://example.com/path?myParam=paramValue. However, only if you configured the $locationProvider in the HTML 5 mode before:

$locationProvider.html5Mode(true);

Otherwise have a look at the http://example.com/#!/path?myParam=someValue "Hashbang" syntax which is a bit more complicated, but have the benefit of working on old browsers (non-HTML 5 compatible) as well.

Use the keyword next. If you do not want to continue to the next item, use break.

When next is used within a block, it causes the block to exit immediately, returning control to the iterator method, which may then begin a new iteration by invoking the block again:

f.each do |line|              # Iterate over the lines in file f
  next if line[0,1] == "#"    # If this line is a comment, go to the next
  puts eval(line)
end

When used in a block, break transfers control out of the block, out of the iterator that invoked the block, and to the first expression following the invocation of the iterator:

f.each do |line|             # Iterate over the lines in file f
  break if line == "quit\n"  # If this break statement is executed...
  puts eval(line)
end
puts "Good bye"              # ...then control is transferred here

And finally, the usage of return in a block:

return always causes the enclosing method to return, regardless of how deeply nested within blocks it is (except in the case of lambdas):

def find(array, target)
  array.each_with_index do |element,index|
    return index if (element == target)  # return from find
  end
  nil  # If we didn't find the element, return nil
end

You can align it like that:

print('{:>8} {:>8} {:>8}'.format(*words))

where > means "align to right" and 8 is the width for specific value.

And here is a proof:

>>> for line in [[1, 128, 1298039], [123388, 0, 2]]:
    print('{:>8} {:>8} {:>8}'.format(*line))


       1      128  1298039
  123388        0        2

Ps. *line means the line list will be unpacked, so .format(*line) works similarly to .format(line[0], line[1], line[2]) (assuming line is a list with only three elements).

No -P needed; -E is sufficient:

grep -E '(^|\s)abc(\s|$)' 

or even without -E:

grep '\(^\|\s\)abc\(\s\|$\)' 

It depends on how fast you want to close your app.

A safe way to close your app is finishAffinity();

It closes you app after all processes finished processing. This may need some time. If you close your app this way, and restart it after a short time, it is possible that your new application runs in the same process. With all the not finished processes and singleton objects of the old application.

If you want to be sure, that your app is closed completly use System.exit(0);

This will close your app immediatly. But it is possible, that you damage files that your app has open or an edit on shared preferences does not finish. So use this carefully.

If you use watchdog in combination with a long running task, you can see the influences of the different methods.

new ANRWatchDog(2000).setANRListener(new ANRWatchDog.ANRListener() {
    public void onAppNotResponding(ANRError error) {
        MainActivity.this.finishAffinity();
        System.exit(0);
    }
}).start();
for(int i = 0; i < 10; ++i){
    --i;
}

This kills your app after 2 seconds without displaying an ANR dialog or something like that. If you remove System.exit(0), run this code and restart the app after it is closed, you will experience some strange behaviour, because the endless loop is still running.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

Read @cupcake's answer for explanations. Here I only try to automate the fix.

If you using Cygwin terminal with BASH, add the following to $HOME/.bashrc file. This only starts ssh-agent once in the first Bash terminal and adds the keys to ssh-agent. (Not sure if this is required on Linux)

###########################
# start ssh-agent for
# ssh authentication with github.com
###########################
SSH_AUTH_SOCK_FILE=/tmp/SSH_AUTH_SOCK.sh
if [ ! -e $SSH_AUTH_SOCK_FILE ]; then
    # need to find SSH_AUTH_SOCK again.
    # restarting is an easy option
    pkill ssh-agent
fi
# check if already running
SSH_AGENT_PID=`pgrep ssh-agent`
if [ "x$SSH_AGENT_PID" == "x" ]; then
#   echo "not running. starting"
    eval $(ssh-agent -s) > /dev/null
    rm -f $SSH_AUTH_SOCK_FILE
    echo "export SSH_AUTH_SOCK=$SSH_AUTH_SOCK" > $SSH_AUTH_SOCK_FILE
    ssh-add $HOME/.ssh/github.com_id_rsa 2>&1 > /dev/null
#else
#   echo "already running"
fi
source $SSH_AUTH_SOCK_FILE

DONT FORGET to add your correct keys in "ssh-add" command.

I tried the above methods for pushing an object into an array of objects in useState but had the following error when using TypeScript:

Type 'TxBacklog[] | undefined' must have a 'Symbol.iterator' method that returns an iterator.ts(2488)

The setup for the tsconfig.json was apparently right:

{
   "compilerOptions": {
   "target": "es6",
   "lib": [
      "dom",
      "dom.iterable",
      "esnext",
      "es6",
],

This workaround solved the problem (my sample code):

Interface:

   interface TxBacklog {
      status: string,
      txHash: string,
   }

State variable:

    const [txBacklog, setTxBacklog] = React.useState<TxBacklog[]>();

Push new object into array:

    // Define new object to be added
    const newTx = {
       txHash: '0x368eb7269eb88ba86..',
       status: 'pending'
    };
    // Push new object into array
    (txBacklog) 
       ? setTxBacklog(prevState => [ ...prevState!, newTx ])
       : setTxBacklog([newTx]);

it's file:///android_asset/... not file:///android_assets/... notice the plural of assets is wrong even if your file name is assets

As Sagiv b.g. pointed out, the npm start command is a shortcut for npm run start. I just wanted to add a real-life example to clarify it a bit more.

The setup below comes from the create-react-app github repo. The package.json defines a bunch of scripts which define the actual flow.

"scripts": {
  "start": "npm-run-all -p watch-css start-js",
  "build": "npm run build-css && react-scripts build",
  "watch-css": "npm run build-css && node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/ --watch --recursive",
  "build-css": "node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/",
  "start-js": "react-scripts start"
},

For clarity, I added a diagram.

The blue boxes are references to scripts, all of which you could executed directly with an npm run <script-name> command. But as you can see, actually there are only 2 practical flows:

• npm run start
• npm run build

The grey boxes are commands which can be executed from the command line.

So, for instance, if you run npm start (or npm run start) that actually translate to the npm-run-all -p watch-css start-js command, which is executed from the commandline.

In my case, I have this special npm-run-all command, which is a popular plugin that searches for scripts that start with "build:", and executes all of those. I actually don't have any that match that pattern. But it can also be used to run multiple commands in parallel, which it does here, using the -p <command1> <command2> switch. So, here it executes 2 scripts, i.e. watch-css and start-js. (Those last mentioned scripts are watchers which monitor file changes, and will only finish when killed.)

• The watch-css makes sure that the *.scss files are translated to *.cssfiles, and looks for future updates.

• The start-js points to the react-scripts start which hosts the website in a development mode.

In conclusion, the npm start command is configurable. If you want to know what it does, then you have to check the package.json file. (and you may want to make a little diagram when things get complicated).

I'm seeing this issue using Rails 4.0.2 and compass-rails 1.1.3

I got past this error by moving gem 'compass-rails' outside of the :assets group in my Gemfile

It looks something like this:

# stuff
gem 'compass-rails', '~> 1.1.3'
group :assets do
  # more stuff
end

We copy the JRE's truststore and add our custom certificates to that truststore, then tell the application to use the custom truststore with a system property. This way we leave the default JRE truststore alone.

The downside is that when you update the JRE you don't get its new truststore automatically merged with your custom one.

You could maybe handle this scenario by having an installer or startup routine that verifies the truststore/jdk and checks for a mismatch or automatically updates the truststore. I don't know what happens if you update the truststore while the application is running.

This solution isn't 100% elegant or foolproof but it's simple, works, and requires no code.

I found that using the following, simple code did the trick (requires custom image in bundle):

// Creates a back button instead of default behaviour (displaying title of previous screen)
    UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back_arrow.png"]
                                                                   style:UIBarButtonItemStyleBordered
                                                                  target:self
                                                                  action:@selector(backAction)];

    tipsDetailViewController.navigationItem.leftBarButtonItem = backButton;
    [backButton release];

One table scan method using a left join from defaults to actuals:

CREATE TABLE [stackoverflow-285666] (k int, val varchar(255))

INSERT  INTO [stackoverflow-285666]
VALUES  (1, '1-1')
INSERT  INTO [stackoverflow-285666]
VALUES  (1, '1-2')
INSERT  INTO [stackoverflow-285666]
VALUES  (1, '1-3')
INSERT  INTO [stackoverflow-285666]
VALUES  (2, '2-1')
INSERT  INTO [stackoverflow-285666]
VALUES  (2, '2-2')

DECLARE @k AS int
SET @k = 0

WHILE @k < 3
    BEGIN
        SELECT  @k AS k
               ,COALESCE(ActualValue, DefaultValue) AS [Value]
        FROM    (
                 SELECT 'DefaultValue' AS DefaultValue
                ) AS Defaults
        LEFT JOIN (
                   SELECT   val AS ActualValue
                   FROM     [stackoverflow-285666]
                   WHERE    k = @k
                  ) AS [Values]
                ON 1 = 1

        SET @k = @k + 1
    END

DROP TABLE [stackoverflow-285666]

Gives output:

k           Value

k           Value
----------- ------------
1           1-1

For my scheduler, I am using it to fire at 6 am every day and my cron notation is:

0 0 6 * * *

If you want 1:01:am then set it to

0 1 1 * * *

Complete code for the scheduler

@Scheduled(cron="0 1 1 * * *")
public void doScheduledWork() {
    //complete scheduled work
}

** VERY IMPORTANT

To be sure about the firing time correctness of your scheduler, you have to set zone value like this (I am in Istanbul):

@Scheduled(cron="0 1 1 * * *", zone="Europe/Istanbul")
public void doScheduledWork() {
    //complete scheduled work
}

You can find the complete time zone values from here.

Notice that '10' is the representation of the base in that base:

10 is 2(decimal) in base-2

10 is 3(decimal) in base-3

...

10 is 10(decimal) in base-10

...

10 is 16(decimal) in base-16 (hexadecimal)

...

10 is 1024(decimal) in base-1024

...and so on

!!(24%1) // false
!!(24.2%1) // true

Not answering the question directly, but it might help someone else.

I have a column called Volume, having both - (invalid/NaN) and numbers formatted with ,

df['Volume'] = df['Volume'].astype('str')
df['Volume'] = df['Volume'].str.replace(',', '')
df['Volume'] = pd.to_numeric(df['Volume'], errors='coerce')

Casting to string is required for it to apply to str.replace

pandas.Series.str.replace
pandas.to_numeric

Here is another way to display PDF inside Div by using Iframe like below.

<div>_x000D_
  <iframe src="/pdf/test.pdf" style="width:100%;height:700px;"></iframe>_x000D_
</div>_x000D_
<div>_x000D_
  <!-- I agree button -->_x000D_
</div>

Yup. Function references are just like any other object reference, you can pass them around to your heart's content.

Here's a more concrete example:

function foo() {
    console.log("Hello from foo!");
}

function caller(f) {
    // Call the given function
    f();
}

function indirectCaller(f) {
    // Call `caller`, who will in turn call `f`
    caller(f);
}

// Do it
indirectCaller(foo); // logs "Hello from foo!"

You can also pass in arguments for foo:

function foo(a, b) {
    console.log(a + " + " + b + " = " + (a + b));
}

function caller(f, v1, v2) {
    // Call the given function
    f(v1, v2);
}

function indirectCaller(f, v1, v2) {
    // Call `caller`, who will in turn call `f`
    caller(f, v1, v2);
}

// Do it
indirectCaller(foo, 1, 2); // logs "1 + 2 = 3"

Calling toDate will create a copy (the documentation is down-right wrong about it not being a copy), of the underlying JS Date object. JS Date object is stored in UTC and will always print to eastern time. Without getting into whether .utc() modifies the underlying object that moment wraps use the code below.

You don't need moment for this.

new Date().getTime()

This works, because JS Date at its core is in UTC from the Unix Epoch. It's extraordinarily confusing and I believe a big flaw in the interface to mix local and UTC times like this with no descriptions in the methods.

The problem:

Microsoft Office 2010 products (or later) install updates that break compatibility of MSCOMCTL.ocx and COMCTL32.ocx. Unfortunately this affects many other programs such Visual Basic 6 SP6 and even Oracle Virtual Box v5. The actual problem is HKEY_CLASSES_ROOT\TypeLib\{831FDD16-0C5C-11D2-A9FC-0000F8754DA1}\2.0 registry key. You can find detailed background information about this problem here.

Here is another working solution:

The solution assumes you have not damaged your registry by deleting, replacing and re-registering MSCOMCTL.ocx and COMCTL32.ocx without unregistering the Office patch files.

Create a batch file called fix.cmd and place the following commands in it:

regsvr32 /s /u %windir%\SysWOW64\comctl32.ocx
regsvr32 /s /u %windir%\SysWOW64\mscomctl.ocx
del /y %windir%\SysWOW64\comctl32.ocx
del /y %windir%\SysWOW64\mscomctl.ocx
msiexec /passive /norestart /i KB2708437.msi
msiexec /passive /a KB2708437.msi
regtlib %windir%\SysWOW64\msdatsrc.tlb

Download from Security update for Visual Basic 6.0 Service Pack 6: August 14, 2012 the msi file and rename it to KB2708437.msi.

Note: A direct link to the Service Pack 6 download is located HERE.

Run fix.cmd and the problem will be fixed!

What fix.cmd does is to properly unregister and then delete the current MSCOMCTL.ocx and COMCTL32.ocx files, and then apply the latest Visual Basic 6 SP6 rollup patch. In fact, the script enforces the patch to be installed and then re-installed by updating every file, regardless of version. Finally it registers msdatsrc.tlb type library.

Please let me know if this works for you.

======================================================================

Advanced Solution:

If however you have accidentally damaged your registry, you need to get as many versions of MSCOMCTL.ocx and COMCTL32.ocx you can find. Then you need to start from the newer version going back to the older and register and unregister the ocx files.

The latest version of MSCOMCTL.ocx is 6.1.98.39 (v2.1) of May 2012 which is more likely the one installed on your system and causing all your problems.

The oldest (legacy) version is that shipped with Visual Basic 6 on 1998 6.1.97.82 (v2.0), or the one shipped with an early service pack 6.1.97.86 on April 2005.

Example:

regsvr32 /s comctl32.6.0.98.34.ocx
regsvr32 /s /u comctl32.6.0.98.34.ocx

regsvr32 /s comctl32.6.0.81.6.ocx
regsvr32 /s /u comctl32.6.0.81.6.ocx 

regsvr32 /s comctl32.6.0.81.5.ocx
regsvr32 /s /u comctl32.6.0.81.5.ocx

regsvr32 /s mscomctl.6.1.98.39.(2.1).ocx
regsvr32 /s /u mscomctl.6.1.98.39.(2.1).ocx

regsvr32 /s mscomctl.6.1.98.34.ocx
regsvr32 /s /u mscomctl.6.1.98.34.ocx

regsvr32 /s mscomctl.6.1.97.86.ocx
regsvr32 /s /u mscomctl.6.1.97.86.ocx

regsvr32 /s mscomctl.6.1.97.82.(2.0).ocx
regsvr32 /s /u mscomctl.6.1.97.82.(2.0).ocx

regsvr32 /s /u %windir%\SysWOW64\comctl32.ocx
regsvr32 /s /u %windir%\SysWOW64\mscomctl.ocx

del /q %windir%\SysWOW64\comctl32.ocx
del /q %windir%\SysWOW64\mscomctl.ocx

msiexec /passive /norestart /i KB2708437.msi
msiexec /passive /a KB2708437.msi

regtlib %windir%\SysWOW64\msdatsrc.tlb   

WARNING:

Do not search the internet for those files. To find different version of the OCX files download and extract official Microsoft Installer packages such as the following:

2005 Apr - Microsoft KB896559

2008 Dec - Microsoft KB926857

2009 Apr - Microsoft KB957924

2012 May - Microsoft KB2708437

It is also recommended to run CCleaner version 4.0 or later to fix any other ActiveX related problems on your computer.

...or alternatively if you only want to show a portion of the time value use "Custom":

timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Custom;
timePicker.CustomFormat = "HH:mm"; // Only use hours and minutes
timePicker.ShowUpDown = true;

Try this:

string[] computer_name = System.Net.Dns.GetHostEntry(System.Web.HttpContext.Current.Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' });
return computer_name[0].ToString();

My answer does not require any additional libraries, and it's easy to understand. But you have to notice that if there's more than one number inside a string, my code will concatenate them together.

def search_number_string(string):
    index_list = []
    del index_list[:]
    for i, x in enumerate(string):
        if x.isdigit() == True:
            index_list.append(i)
    start = index_list[0]
    end = index_list[-1] + 1
    number = string[start:end]
    return number

Your two examples look identical, which makes problems hard to diagnose. Potential problems:

1. You may need double quotes, as in sed 's/xxx/'"$PWD"'/'

2. $PWD may contain a slash, in which case you need to find a character not contained in $PWD to use as a delimiter.

To nail both issues at once, perhaps

sed 's@xxx@'"$PWD"'@'

Also, in .NET 4 this is even easier if you use the dynamic keyword:

dynamic document = this.browser.Document;
dynamic head = document.GetElementsByTagName("head")[0];
dynamic scriptEl = document.CreateElement("script");
scriptEl.text = ...;
head.AppendChild(scriptEl);

A little late but I was having this problem too and running studio as root just created more problems (using OSX here).

I fixed it by manually installing what was failing to install using the Android SDK manager. Just run android sdk in a terminal (probably the same on Windows but don't quote me). Let it install all the updates it wants, then if you can't make it through the setup, manually find the packages that are failing to install and install them.

Got me through a very frustrating problem and back to work.....

Put them into a list and use merge with Reduce

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

If for some reason you can't get your hands on any of the Python modules that other users mentioned, I suggest the following solution for Python 2.7:

import subprocess

def makePretty(filepath):
  cmd = "xmllint --format " + filepath
  prettyXML = subprocess.check_output(cmd, shell = True)
  with open(filepath, "w") as outfile:
    outfile.write(prettyXML)

As far as I know, this solution will work on Unix-based systems that have the xmllint package installed.

INNER JOIN requires there is at least a match in comparing the two tables. For example, table A and table B which implies A ? B (A intersection B).

LEFT OUTER JOIN and LEFT JOIN are the same. It gives all the records matching in both tables and all possibilities of the left table.

Similarly, RIGHT OUTER JOIN and RIGHT JOIN are the same. It gives all the records matching in both tables and all possibilities of the right table.

FULL JOIN is the combination of LEFT OUTER JOIN and RIGHT OUTER JOIN without duplication.

Recently I was also having this issue, then I contacted Google Support and they gave me this link to provide required info, I posted and within 24 hours my problem was fixed.

The key checks for FAST REFRESH includes the following:

1) An Oracle materialized view log must be present for each base table.
2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition.
3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.

No 3 is easy to miss and worth highlighting here

it dows not work with the :input selector for select fields, use this:

    jQuery(function() {

    jQuery('form').bind('submit', function() {
        jQuery(this).find(':disabled').removeAttr('disabled');
    });

    });

You have to use the component's State to update component parameters such as Class Name if you want React to render your DOM correctly and efficiently.

UPDATE: I updated the example to toggle the Sidemenu on a button click. This is not necessary, but you can see how it would work. You might need to use "this.state" vs. "this.props" as I have shown. I'm used to working with Redux components.

constructor(props){
    super(props);
}

getInitialState(){
  return {"showHideSidenav":"hidden"};
}

render() {
    return (
        <div className="header">
            <i className="border hide-on-small-and-down"></i>
            <div className="container">
                <a ref="btn" onClick={this.toggleSidenav.bind(this)} href="#" className="btn-menu show-on-small"><i></i></a>
                <Menu className="menu hide-on-small-and-down"/>
                <Sidenav className={this.props.showHideSidenav}/>
            </div>
        </div>
    )
}

toggleSidenav() {
    var css = (this.props.showHideSidenav === "hidden") ? "show" : "hidden";
    this.setState({"showHideSidenav":css});
}

Now, when you toggle the state, the component will update and change the class name of the sidenav component. You can use CSS to show/hide the sidenav using the class names.

.hidden {
   display:none;
}
.show{
   display:block;
}

@jovi all you need to do is add .babelrc file like this:

{
  "plugins": [
    "transform-strict-mode",
    "transform-es2015-modules-commonjs",
    "transform-es2015-spread",
    "transform-es2015-destructuring",
    "transform-es2015-parameters"
  ]
}

and install these plugins as devdependences with npm.

then try babel-node ***.js again. hope this can help you.

I would change your binding to be:

<button type="button" value="click me" onclick="check_me" />

I would then change your check_me() function declaration to be:

function check_me() {   
  //event.preventDefault();
  var hello = document.myForm.username.value;
  var err = '';

  if(hello == '' || hello == null) {
    err = 'User name required';
  }

  if(err != '') { 
     alert(err); 
     $('username').focus(); 
     event.preventDefault(); 
   } else { 
    return true; }
}

When you overload in TypeScript, you only have one implementation with multiple signatures.

class Foo {
    myMethod(a: string);
    myMethod(a: number);
    myMethod(a: number, b: string);
    myMethod(a: any, b?: string) {
        alert(a.toString());
    }
}

Only the three overloads are recognized by TypeScript as possible signatures for a method call, not the actual implementation.

In your case, I would personally use two methods with different names as there isn't enough commonality in the parameters, which makes it likely the method body will need to have lots of "ifs" to decide what to do.

TypeScript 1.4

As of TypeScript 1.4, you can typically remove the need for an overload using a union type. The above example can be better expressed using:

myMethod(a: string | number, b?: string) {
    alert(a.toString());
}

The type of a is "either string or number".

Just add to @Bert's solution to make it more clear:

    const routes = [
  { path: '/foo', component: Foo },
  { path: '/bar', component: Bar }
]

const router = new VueRouter({
  routes,
  linkExactActiveClass: "active" // active class for *exact* links.
})

As one can see, this line should be removed:

linkActiveClass: "active", // active class for non-exact links.

this way, ONLY the current link is hi-lighted. This should apply to most of the cases.

Simplest of all solutions:

Add the below code in CSS:

.tableClassName tbody {
  display: block;
  max-height: 200px;
  overflow-y: scroll;
}

.tableClassName thead, .tableClassName tbody tr {
  display: table;
  width: 100%;
  table-layout: fixed;
}
.tableClassName thead {
  width: calc( 100% - 1.1em );
}

1.1 em is the average width of the scroll bar, please modify this if needed.

Use a pattern along these lines:

function getValue(file) {
  return lookupValue(file);
}

getValue('myFile.txt').then(function(res) {
  // do whatever with res here
});

(although this is a bit redundant, I'm sure your actual code is more complicated)

Visual Studio's Error List pane only shows you the first line of the error. Invoke View>Output and I bet you'll see something like:

c:\path\to\your\code.cpp(42): error C2259: 'AmbientOccluder' : cannot instantiate abstract class
          due to following members:
          'ULONG MysteryUnimplementedMethod(void)' : is abstract
          c:\path\to\some\include.h(8) : see declaration of 'MysteryUnimplementedMethod'

length = 4
string = "abcdefgh"
str_dict = [ o for o in string ]
parts = [ ''.join( str_dict[ (j * length) : ( ( j + 1 ) * length ) ]   ) for j in xrange(len(string)/length  )]

A bit late but this worked for me

  $data_id = $this->input->get('name_of_field');

(Header CSS:)

<style>

a  {   
   color: #ccc;   /* original colour state*/
}

a:active {
   color: #F66;  
}


a[tabindex]:focus {
    color: #F66;
    outline: none;
}

</style>


(Body HTML:)

<a href="javascript:;" style="font-size:36px; text-decoration:none;"  tabindex="1">click me &#9829;</a>

The answers are partially correct. I also faced the same problem. Parsing the json and checking for exception seems the usual way but the solution fails for the input json something like

{"outputValueSchemaFormat": "","sortByIndexInRecord": 0,"sortOrder":847874874387209"descending"}kajhfsadkjh

As you can see the json is invalid as there are trailing garbage characters. But if you try to parse the above json using jackson or gson then you will get the parsed map of the valid json and garbage trailing characters are ignored. Which is not the required solution when you are using the parser for checking json validity.

For solution to this problem see here.

PS: This question was asked and answered by me.

I have defined this function:

function format() {
        var args = arguments;
        if (args.length <= 1) { 
            return args;
        }
        var result = args[0];
        for (var i = 1; i < args.length; i++) {
            result = result.replace(new RegExp("\\{" + (i - 1) + "\\}", "g"), args[i]);
        }
        return result;
    }

And can be called like c#:

 var text = format("hello {0}, your age is {1}.",  "John",  29);

Result:

hello John, your age is 29.

this query return last record for every Form_id:

    SELECT m1.*
     FROM messages m1 LEFT JOIN messages m2
     ON (m1.Form_id = m2.Form_id AND m1.id < m2.id)
     WHERE m2.id IS NULL;

You are asking the wrong question. In databases is not the operator performance that matters, is always the SARGability of the expression, and the coverability of the overall query. Performance of the operator itself is largely irrelevant.

So, how do LIKE and = compare in terms of SARGability? LIKE, when used with an expression that does not start with a constant (eg. when used LIKE '%something') is by definition non-SARGabale. But does that make = or LIKE 'something%' SARGable? No. As with any question about SQL performance the answer does not lie with the query of the text, but with the schema deployed. These expression may be SARGable if an index exists to satisfy them.

So, truth be told, there are small differences between = and LIKE. But asking whether one operator or other operator is 'faster' in SQL is like asking 'What goes faster, a red car or a blue car?'. You should eb asking questions about the engine size and vechicle weight, not about the color... To approach questions about optimizing relational tables, the place to look is your indexes and your expressions in the WHERE clause (and other clauses, but it usually starts with the WHERE).

Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80 (there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80. Make sure that View ? Word Wrap is selected.

To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User and use any of the following rules:

{
    // set vertical rulers in specified columns.
    // Use "rulers": [80] for just one ruler
    // default value is []
    "rulers": [80, 100, 120],

    // turn on word wrap for source and text
    // default value is "auto", which means off for source and on for text
    "word_wrap": true,

    // set word wrapping at this column
    // default value is 0, meaning wrapping occurs at window width
    "wrap_width": 80
}

These settings can also be used in a .sublime-project file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings file if you only want them to apply to files written in a certain language (Python.sublime-settings vs. JavaScript.sublime-settings, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User.

As always, if you have multiple entries in your settings file, separate them with commas , except for after the last one. The entire content should be enclosed in curly braces { }. Basically, make sure it's valid JSON.

If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.

Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0 and O (digit zero and capital letter oh) and 1 and l (digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).

I found a fairly robust solution at https://gallery.technet.microsoft.com/scriptcenter/c0c57332-8624-48c0-b4c3-5b31fe641c58 , which I thought was worth pointing out. It searches columns of these types: varchar, char, nvarchar, nchar, text. It works great and supports specific table-searching as well as multiple search-terms.

All of the other answers were either deprecated or didn't work for HttpClient 4.3.

Here is a way to allow all hostnames when building an http client.

CloseableHttpClient httpClient = HttpClients
    .custom()
    .setHostnameVerifier(new AllowAllHostnameVerifier())
    .build();

Or if you are using version 4.4 or later, the updated call looks like this:

CloseableHttpClient httpClient = HttpClients
    .custom()
    .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
    .build();

Bear in mind the consequences

SELECT REPLACE(REPLACE('TEST123','123','456'),'45','89') FROM DUAL;

will replace the 123 with 456, then find that it can replace the 45 with 89. For a function that had an equivalent result, it would have to duplicate the precedence (ie replacing the strings in the same order).

Similarly, taking a string 'ABCDEF', and instructing it to replace 'ABC' with '123' and 'CDE' with 'xyz' would still have to account for a precedence to determine whether it went to '123EF' or ABxyzF'.

In short, it would be difficult to come up with anything generic that would be simpler than a nested REPLACE (though something that was more of a sprintf style function would be a useful addition).

New answer (2016-04-20)

Using Spring Boot 1.3.1.RELEASE

New Step 1 - It is easy and less intrusive to add the following properties to the application.properties:

spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false

Much easier than modifying the existing DispatcherServlet instance (as below)! - JO'

If working with a full RESTful Application, it is very important to disable the automatic mapping of static resources since if you are using Spring Boot's default configuration for handling static resources then the resource handler will be handling the request (it's ordered last and mapped to /** which means that it picks up any requests that haven't been handled by any other handler in the application) so the dispatcher servlet doesn't get a chance to throw an exception.

New Answer (2015-12-04)

Using Spring Boot 1.2.7.RELEASE

New Step 1 - I found a much less intrusive way of setting the "throExceptionIfNoHandlerFound" flag. Replace the DispatcherServlet replacement code below (Step 1) with this in your application initialization class:

@ComponentScan()
@EnableAutoConfiguration
public class MyApplication extends SpringBootServletInitializer {
    private static Logger LOG = LoggerFactory.getLogger(MyApplication.class);
    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(MyApplication.class, args);
        DispatcherServlet dispatcherServlet = (DispatcherServlet)ctx.getBean("dispatcherServlet");
        dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
    }

In this case, we're setting the flag on the existing DispatcherServlet, which preserves any auto-configuration by the Spring Boot framework.

One more thing I've found - the @EnableWebMvc annotation is deadly to Spring Boot. Yes, that annotation enables things like being able to catch all the controller exceptions as described below, but it also kills a LOT of the helpful auto-configuration that Spring Boot would normally provide. Use that annotation with extreme caution when you use Spring Boot.

Original Answer:

After a lot more research and following up on the solutions posted here (thanks for the help!) and no small amount of runtime tracing into the Spring code, I finally found a configuration that will handle all Exceptions (not Errors, but read on) including 404s.

Step 1 - tell SpringBoot to stop using MVC for "handler not found" situations. We want Spring to throw an exception instead of returning to the client a view redirect to "/error". To do this, you need to have an entry in one of your configuration classes:

// NEW CODE ABOVE REPLACES THIS! (2015-12-04)
@Configuration
public class MyAppConfig {
    @Bean  // Magic entry 
    public DispatcherServlet dispatcherServlet() {
        DispatcherServlet ds = new DispatcherServlet();
        ds.setThrowExceptionIfNoHandlerFound(true);
        return ds;
    }
}

The downside of this is that it replaces the default dispatcher servlet. This hasn't been a problem for us yet, with no side effects or execution problems showing up. If you're going to do anything else with the dispatcher servlet for other reasons, this is the place to do them.

Step 2 - Now that spring boot will throw an exception when no handler is found, that exception can be handled with any others in a unified exception handler:

@EnableWebMvc
@ControllerAdvice
public class ServiceExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(Throwable.class)
    @ResponseBody
    ResponseEntity<Object> handleControllerException(HttpServletRequest req, Throwable ex) {
        ErrorResponse errorResponse = new ErrorResponse(ex);
        if(ex instanceof ServiceException) {
            errorResponse.setDetails(((ServiceException)ex).getDetails());
        }
        if(ex instanceof ServiceHttpException) {
            return new ResponseEntity<Object>(errorResponse,((ServiceHttpException)ex).getStatus());
        } else {
            return new ResponseEntity<Object>(errorResponse,HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }

    @Override
    protected ResponseEntity<Object> handleNoHandlerFoundException(NoHandlerFoundException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
        Map<String,String> responseBody = new HashMap<>();
        responseBody.put("path",request.getContextPath());
        responseBody.put("message","The URL you have reached is not in service at this time (404).");
        return new ResponseEntity<Object>(responseBody,HttpStatus.NOT_FOUND);
    }
    ...
}

Keep in mind that I think the "@EnableWebMvc" annotation is significant here. It seems that none of this works without it. And that's it - your Spring boot app will now catch all exceptions, including 404s, in the above handler class and you may do with them as you please.

One last point - there doesn't seem to be a way to get this to catch thrown Errors. I have a wacky idea of using aspects to catch errors and turn them into Exceptions that the above code can then deal with, but I have not yet had time to actually try implementing that. Hope this helps someone.

Any comments/corrections/enhancements will be appreciated.

Why venture that far when you could just use System.Web.HttpUtility.JavaScriptEncode ?

                sb.Append(src, start, i - start);
                switch (src[i])
                {
                    case '\b': sb.Append("\\b"); break;
                    case '\f': sb.Append("\\f"); break;

                    case '/': sb.Append("\\/"); break;

Try putting this in your .htaccess file:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^sub.domain.com
RewriteRule ^(.*)$ /subdomains/sub/$1 [L,NC,QSA]

For a more general rule (that works with any subdomain, not just sub) replace the last two lines with this:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ subdomains/%1/$1 [L,NC,QSA]

save() can take a file-like object as well as a path, so you can use an in-memory buffer like a StringIO:

buf = StringIO.StringIO()
im.save(buf, format='JPEG')
jpeg = buf.getvalue()

table{border-collapse:collapse;}

app.manifest should be like this:

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

The accepted answer is out of date. Some of the suggestions were already incorporated in the package, and I was still getting the error about missing config-win.h & mysqlclient.lib.

• Install mysql-connector-c-6.0.2-win32.msi

  There's a zip file for the conenctor too but that didn't work because mysqlclient.lib is in lib directory whereas the installer expects it in lib/opt. Instead of hacking site.cfg or setup_windows.py, the msi does the job.

• pip install mysql-python

P.S. Since I don't use MySQL anymore, my answer may be out of date as well.

You can use Query.values, Query.values

session.query(SomeModel).values('id', 'user')

On Samsung go to "Settings" -> "Lock screen and security" -> "Other security settings" -> "Phone administrators" and deselect the admin which you want to uninstall.

The "security" word was hidden on my display, so it was not obvious that I should click on "Lock screen".

try

<select onchange="location=this.value">_x000D_
    <option value="unit_01.htm">Unit 1</option>_x000D_
    <option value="#5.2" selected >Bookmark 2</option>_x000D_
</select>

In addition, sometimes the dict instance might be a subclass of dict (defaultdict for example). In that case, using clear is preferred, as we don't have to remember the exact type of the dict, and also avoid duplicate code (coupling the clearing line with the initialization line).

x = defaultdict(list)
x[1].append(2)
...
x.clear() # instead of the longer x = defaultdict(list)

Simple! "origin" is just what you nicknamed your remote repository when you ran a command like this:

git remote add origin [email protected]:USERNAME/REPOSITORY-NAME.git

From then on Git knows that "origin" points to that specific repository (in this case a GitHub repository). You could have named it "github" or "repo" or whatever you wanted.

Why don't you just stack them ::

$("#clickedItem").click(function(){
  $("#animatedItem").animate( // );
}).toggle( // <--- you just stack the toggle function here ...
function(){
  $(this).text( // );
},
function(){
  $(this).text( // );
});

The main issue with 301 is browser will cache the redirection even if you disabled the redirection from the server level.

Its always better to use 302 if you are enabling the redirection for a short maintenance window.

Here is the code you need:

start cmd.exe @cmd /k "Command"

If table1 is large and you don't want to lock it for the duration of the copy process, you can do a dump-and-load instead:

CREATE TABLE table2 LIKE table1;

SELECT * INTO OUTFILE '/tmp/table1.txt' FROM table1;
LOAD DATA INFILE '/tmp/table1.txt' INTO TABLE table2;

I'm used it and worked perfectly...

startActivity(new Intent(getApplicationContext(),MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)); 

because Finish() use for 2 activities, not for multiple activities

The call to time(NULL) returns the current calendar time (seconds since Jan 1, 1970). See this reference for details. Ordinarily, if you pass in a pointer to a time_t variable, that pointer variable will point to the current time.

Here are several ways you can do it in Theta(N) running time

from collections import defaultdict

def mode1(L):
    counts = defaultdict(int)
    for v in L:
        counts[v] += 1
    return max(counts,key=lambda x:counts[x])

def mode2(L):
    vals = set(L)
    return max(vals,key=lambda x: L.count(x))

def mode3(L):
    return max(set(L), key=lambda x: L.count(x))

For those who want an elegant, bash version-independent solution (in fact should work in other modern shells) and those who love to use one-liners for quick tasks. Here we go!

ls | grep . && echo 'files found' || echo 'files not found'

(note as one of the comments mentioned, ls -al and in fact, just -l and -a will all return something, so in my answer I use simple ls

You need to do custom SQL as exemplified in this snippet:

Custom SQL via subquery

Or in a custom manager as shown in the online Django docs:

Adding extra Manager methods

I looked at several of the options. Here are my two favorites, because I needed to round the value.

You're looking for the wrong selector id:

 $("#submitter").text(submitter_name);

should be

 $("#submittername").text(submitter_name);

Just to complete this with an equivalent method chain syntax:

entity.Join(entity2, x => new {x.Field1, x.Field2},
                     y => new {y.Field1, y.Field2}, (x, y) => x);

While the last argument (x, y) => x is what you select (in the above case we select x).

All arrays passed to php must be object literals. Here's an example from JS/jQuery:

var myarray = {};  //must be declared as an object literal first

myarray[fld1] = val;  // then you can add elements and values
myarray[fld2] = val;
myarray[fld3] = Array();  // array assigned to an element must also be declared as object literal

etc...`

It can now be sent via Ajax in the data: parameter as follows:

data: { new_name: myarray },

php picks this up and reads it as a normal array without any decoding necessary. Here's an example:

$array = $_POST['new_name'];  // myarray became new_name (see above)
$fld1 = array['fld1'];
$fld2 = array['fld2'];
etc...

However, when you return an array to jQuery via Ajax it must first be encoded using json. Here's an example in php:

$return_array = json_encode($return_aray));
print_r($return_array);

And the output from that looks something like this:

{"fname":"James","lname":"Feducia","vip":"true","owner":"false","cell_phone":"(801) 666-0909","email":"[email protected]", "contact_pk":"","travel_agent":""}

{again we see the object literal encoding tags} now this can be read by JS/jQuery as an array without any further action inside JS/JQuery... Here's an example in jquery ajax:

success: function(result) {
console.log(result);
alert( "Return Values: " + result['fname'] + " " + result['lname'] );
}

Try to just use isNotNull function.

df.filter(df.dt_mvmt.isNotNull()).count()

Use Ajax for this.

Build a function that will fetch the current page via ajax, but not the whole page, just the div in question from the server. The data will then (again via jQuery) be put inside the same div in question and replace old content with new one.

Relevant function:

http://api.jquery.com/load/

e.g.

$('#thisdiv').load(document.URL +  ' #thisdiv');

Note, load automatically replaces content. Be sure to include a space before the id selector.

If you want to update react use npx update react on the terminal.

Here's a fairly simple way to achieve it by enclosing both the magnifying glass icon and the input field inside a div with relative positioning.

Absolute positioning is applied to the icon, which takes it out of the normal document layout flow. The icon is then positioned inside the input. Left padding is applied to the input so that the user's input appears to the right of the icon.

Note that this example places the magnifying glass icon on the left instead of the right. This is recommended when using <input type="search"> as Chrome adds an X button in the right side of the searchbox. If we placed the icon there it would overlay the X button and look fugly.

Here is the needed Bootstrap markup.

<div class="position-relative">
    <i class="fa fa-search position-absolute"></i>
    <input class="form-control" type="search">
</div>

...and a couple CSS classes for the things which I couldn't do with Bootstrap classes:

i {
    font-size: 1rem;
    color: #333;
    top: .75rem;
    left: .75rem
}

input {
    padding-left: 2.5rem;
}

You may have to fiddle with the values for top, left, and padding-left.

From within modules of a python package I had to refer to a file that resided in the same directory as package. Ex.

some_dir/
  maincli.py
  top_package/
    __init__.py
    level_one_a/
      __init__.py
      my_lib_a.py
      level_two/
        __init__.py
        hello_world.py
    level_one_b/
      __init__.py
      my_lib_b.py

So in above I had to call maincli.py from my_lib_a.py module knowing that top_package and maincli.py are in the same directory. Here's how I get the path to maincli.py:

import sys
import os
import imp


class ConfigurationException(Exception):
    pass


# inside of my_lib_a.py
def get_maincli_path():
    maincli_path = os.path.abspath(imp.find_module('maincli')[1])
    # top_package = __package__.split('.')[0]
    # mod = sys.modules.get(top_package)
    # modfile = mod.__file__
    # pkg_in_dir = os.path.dirname(os.path.dirname(os.path.abspath(modfile)))
    # maincli_path = os.path.join(pkg_in_dir, 'maincli.py')

    if not os.path.exists(maincli_path):
        err_msg = 'This script expects that "maincli.py" be installed to the '\
        'same directory: "{0}"'.format(maincli_path)
        raise ConfigurationException(err_msg)

    return maincli_path

Based on posting by PlasmaBinturong I modified the code.

To restore menu bar visibility so that you don't press key Alt to make the menu bar visible and the menu bar remains visible all the time, see the setting below.

You inadvertently changed the value from "default" to "toggle", so restore the setting to "default" as shown below.

"window.menuBarVisibility": "default"

In addition, you need the "AllowOverride Options" directive for this to work. (Apache 2.2.15)

Probably not the most efficient, but think it's a neat way to do it.

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "true"));
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "false"));

    }

    static Int32 CountAllTheTimesThisStringAppearsInThatString(string orig, string find)
    {
        var s2 = orig.Replace(find,"");
        return (orig.Length - s2.Length) / find.Length;
    }
}

If you don't want to use jQuery mobile as like me. You can use Hammer.js

It's mostly like jQuery Mobile without unnecessary code.

$(document).ready(function() {
  Hammer(myCarousel).on("swipeleft", function(){
    $(this).carousel('next');
  });
  Hammer(myCarousel).on("swiperight", function(){
    $(this).carousel('prev');
  });
});

It is a unicode char \u003C = <

If you have a table with just a stored date (no time) and want to get those by "now", then you can do this:

SELECT * FROM tbl WHERE DATEDIFF(d, yourdate, GETDATE())=0

This results in rows which day difference is 0 (so today).

If you're using PHP5.3 or above, you can use numfmt_parse to do "a reversed number_format". If you're not, you stuck with replacing the occurrances with preg_replace/str_replace.

If you plot in IPython console (where you can't use %matplotlib inline) instead of Jupyter notebook, and don't want to run plt.show() repeatedly, you can start IPython console with ipython --pylab:

I've made an alternative to the other good answers on here that uses PowerShell, but mine also saves the list to a file. Will share it here in case anyone else needs wants something like that.

Warning: Code overwrites "longfilepath.txt" in the current working directory. I know it's unlikely you'd have one already, but just in case!

Purposely wanted it in a single line:

Out-File longfilepath.txt ; cmd /c "dir /b /s /a" | ForEach-Object { if ($_.length -gt 250) {$_ | Out-File -append longfilepath.txt}}

Detailed instructions:

1. Run PowerShell
2. Traverse to the directory you want to check for filepath lengths (C: works)
3. Copy and paste the code [Right click to paste in PowerShell, or Alt + Space > E > P]
4. Wait until it's done and then view the file: cat longfilepath.txt | sort

Explanation:

Out-File longfilepath.txt ; – Create (or overwrite) a blank file titled 'longfilepath.txt'. Semi-colon to separate commands.

cmd /c "dir /b /s /a" | – Run dir command on PowerShell, /a to show all files including hidden files. | to pipe.

ForEach-Object { if ($_.length -gt 250) {$_ | Out-File -append longfilepath.txt}} – For each line (denoted as $_), if the length is greater than 250, append that line to the file.

Adding the following path without back slash '\' at the end worked for me. C:\Program Files\Java\jdk1.8.0_31

I recently ran into the same problem, and found a workaround though it'll only be useful if you can change the html code to suit.

I used tables to achieve my padded layout, so to create the equivalent of a div with internal padding I made a table with 3 columns/3 rows and put the content in the centre row/column. The first and last columns/rows are used for the padding.

eg.

<table>
<tr>
    <td width="10">&nbsp;</td>
    <td>&nbsp;</td>
    <td width="10">&nbsp;</td>
</tr>
<tr>
    <td>&nbsp;</td>
    <td>content goes here</td>
    <td>&nbsp;</td>
</tr>
<tr>
    <td width="10">&nbsp;</td>
    <td>&nbsp;</td>
    <td width="10">&nbsp;</td>
</tr>
</table>

Hope that helps.

Joe

This would do the trick, returning the values at indeces 0, 2 and 3.

Array.FindAll(arr, Function(s) s.ToLower().StartsWith("ra"))

According to the PHP.net manual:

If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use isset() to check a variable is registered in $_SESSION.

Daniel LeCheminant's code didn't work for me after converting it from CoffeeScript to JavaScript (js2coffee). It kept bombing out on the _.defer() line.

I assumed this was something to do with jQuery deferreds, so I changed it to $.Deferred() and it's working now. I tested it in Internet Explorer 11, Firefox 35, and Chrome 39 with jQuery 2.1.1. The usage is the same as described in Daniel's post.

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

You can try with this

nFilter.style.cssText = 'width:330px;float:left;';

That should do it for you.

I generally just put a log4j.xml file into src/test/resources and let log4j find it by itself: no code required, the default log4j initialisation will pick it up. (I typically want to set my own loggers to 'DEBUG' anyway)

Update on @ghostJago answer above

for me it worked as the following lines in VS2017

string curDir = Directory.GetCurrentDirectory();
this.webBrowser1.Navigate(new Uri(String.Format("file:///{0}/my_html.html", curDir)));

This is some of the things you can put into a message box. Enjoy
MessageBox.Show("Enter the text for the message box",
