For Windows you can check it using PowerShell

$PathInvalidChars = [System.IO.Path]::GetInvalidPathChars() #36 chars

To display UTF-8 codes you can convert

$enc = [system.Text.Encoding]::UTF8
$PathInvalidChars | foreach { $enc.GetBytes($_) }

$FileNameInvalidChars = [System.IO.Path]::GetInvalidFileNameChars() #41 chars

$FileOnlyInvalidChars = @(':', '*', '?', '\', '/') #5 chars - as a difference

without what? do you mean

>>> print 'a' * 20
aaaaaaaaaaaaaaaaaaaa

?

I used this set up in a react app that works. I created a config file named configstrp.js that contains the following:

module.exports = {
ngrok: {
// use the local frontend port to connect
enabled: process.env.NODE_ENV !== 'production',
port: process.env.PORT || 3000,
subdomain: process.env.NGROK_SUBDOMAIN,
authtoken: process.env.NGROK_AUTHTOKEN
},   }

Require the file in the server.

const configstrp      = require('./config/configstrp.js');
const ngrok = configstrp.ngrok.enabled ? require('ngrok') : null;

and connect as such

if (ngrok) {
console.log('If nGronk')
ngrok.connect(
    {
    addr: configstrp.ngrok.port,
    subdomain: configstrp.ngrok.subdomain,
    authtoken: configstrp.ngrok.authtoken,
    host_header:3000
  },
  (err, url) => {
    if (err) {

    } else {

    }
   }
  );
 }

Do not pass a subdomain if you do not have a custom domain

If you just need to hit C# Method on in your Ajax Call you just need to pass two matter type and url if your request is get then you just need to specify the url only. please follow the code below it's working fine.

C# Code:

    [HttpGet]
    public ActionResult FirstAjax()
    {
        return Json("chamara", JsonRequestBehavior.AllowGet);
    }   

Java Script Code if Get Request

    $.ajax({
        url: 'home/FirstAjax',
        success: function(responce){ alert(responce.data)},
        error: function(responce){ alert(responce.data)}
    });

Java Script Code if Post Request and also [HttpGet] to [HttpPost]

        $.ajax({
            url: 'home/FirstAjax',
            type:'POST',
            success: function(responce){ alert(responce)},
            error: function(responce){ alert(responce)}
        });

Note: If you FirstAjax in same controller in which your View Controller then no need for Controller name in url. like url: 'FirstAjax',

I don't see why this wouldn't work. It's not as concrete as everyone else's answers but if you know the name of your class then it's enough.

def str_to_class(name):
    if name == "Foo":
        return Foo
    elif name == "Bar":
        return Bar

Consistency is the key to any naming standard. As long as it's logical and consistent, you're 99% there.

The standard itself is very much personal preference - so if you like your standard, then run with it.

To answer your question outright - no, MySQL doesn't have a preferred naming convention/standard, so rolling your own is fine (and yours seems logical).

Here is example how to remove NULL characters using ex (in-place):

ex -s +"%s/\%x00//g" -cwq nulls.txt

and for multiple files:

ex -s +'bufdo!%s/\%x00//g' -cxa *.txt

^{For recursivity, you may use globbing option **/*.txt (if it is supported by your shell).}

Useful for scripting since sed and its -i parameter is a non-standard BSD extension.

See also: How to check if the file is a binary file and read all the files which are not?

As stated by many, 404 is misleading and it doesn't allow the client to discriminate if the request uri doesn't exist, or if the requested uri cannot fetch the requested resource.

The 200 status is expected to contain resource data - so it is not the right choice. The 204 status means something else entirely and should not be used as response for GET requests.

All other existing status are not applicable, for one reason or the other.

I have seen this topic being discussed over and over in multiple places. For me, it is painfully obvious that to eliminate the confusion around the topic, a dedicated success status is needed. Something like "209 - No resource to display".

It will be a 2xx status because not finding an ID should not be considered a client error (if the clients knew everything which is in the server's DB, they would not need to ask anything to the server, wouldn't they?). This dedicated status will address all issues debated with using other statuses.

The only question is: how do I get RFC to accept this as a standard?

This should be shorter:

<font color='red'>test blue color font</font>

Make sure when you create a txt file you don't type in the name "name.txt", just type in "name". If you type "name.txt" Eclipse will see it as "name.txt.txt". This solved it for me. Also save the file in the src folder, not the folder were the .java resides, one folder up.

With second precision, you can print tv_sec field of timeval structure that you get from gettimeofday() function. For example:

#include <sys/time.h>
#include <stdio.h>

int main()
{
    struct timeval tv;
    gettimeofday(&tv, NULL);
    printf("Seconds since Jan. 1, 1970: %ld\n", tv.tv_sec);
    return 0;
}

Example of compiling and running:

$ gcc -Wall -o test ./test.c 
$ ./test 
Seconds since Jan. 1, 1970: 1343845834

Note, however, that its been a while since epoch and so long int is used to fit a number of seconds these days.

There are also functions to print human-readable times. See this manual page for details. Here goes an example using ctime():

#include <time.h>
#include <stdio.h>

int main()
{
    time_t clk = time(NULL);
    printf("%s", ctime(&clk));
    return 0;
}

Example run & output:

$ gcc -Wall -o test ./test.c 
$ ./test

printf "\n\n"
printf "******************************\n"
printf "Started Automatic Mysql Backup\n"
printf "******************************\n"
printf "TIME: `now`\n"
printf "IP_ADDRESS: `ip` \n"
printf "DB_SERVER_NAME: DB-SERVER-1\n"

printf "%sBACKUP_FILE_PATH $fullpathbackupfile\n"

printf "Starting Mysql Dump \n"

mysqldump -u $db_user -p$db_password $db_name| pv | zip > $fullpathbackupfile

end_time="$(date -u +%s)"

elapsed=$(($end_time-$start_time))

printf "%sMysql Dump Completed In $elapsed seconds\n"

printf "******************************\n"

PS: Rememember to install pv and zip in your ubuntu

sudo apt install pv
sudo apt install zip

Here is how I set crontab by using crontab -e in ubuntu to run every 6 hours

0 */6 * * * sh /path/to/shfile/backup-mysql.sh >> /path/to/logs/backup-mysql.log 2>&1

Cool thing is it will create a zip file which is easier to unzip from anywhere

import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

resp.read() is the straight html of the page you want to open, and you can use opener to view any page using your session cookie.

DATEADD and GETDATE functions might not work in MySQL database. so if you are working with MySQL database, then the following command may help you.

select id, NewsHeadline as news_headline,    
NewsText as news_text,    
state, CreatedDate as created_on    
from News    
WHERE CreatedDate>= DATE_ADD(CURDATE(), INTERVAL -3 DAY);

I hope it will help you

I run the service at IPLocate.io, which you can hook into for free with one easy call:

<?php
$res = file_get_contents('https://www.iplocate.io/api/lookup/8.8.8.8');
$res = json_decode($res);

echo $res->country; // United States
echo $res->continent; // North America
echo $res->latitude; // 37.751
echo $res->longitude; // -97.822

var_dump($res);

The $res object will contain your geolocation fields like country, city, etc.

Check out the docs for more information.

You can generate the WS proxy classes using WSCF (Web Services Contract First) tool from thinktecture.com. So essentially, YOU CAN create webservices from wsdl's. Creating the asmx's, maybe not, but that's the easy bit isn't it? This tool integrates brilliantly into VS2005-8 (new version for 2010/WCF called WSCF-blue). I've used it loads and always found it to be really good.

There is no performance difference.

A const_iterator is an iterator that points to const value (like a const T* pointer); dereferencing it returns a reference to a constant value (const T&) and prevents modification of the referenced value: it enforces const-correctness.

When you have a const reference to the container, you can only get a const_iterator.

Edited: I mentionned “The const_iterator returns constant pointers” which is not accurate, thanks to Brandon for pointing it out.

Edit: For COW objects, getting a non-const iterator (or dereferencing it) will probably trigger the copy. (Some obsolete and now disallowed implementations of std::string use COW.)

After failing with cleaning the Credentials from the Manager and clearing the VS cache, consider to repair Visual Studio from the Visual Studio Installer (VS2017). I personally found no other solution working.

To change even less on your original query, you can turn your join into a RIGHT join

SELECT person.person_id, COUNT(appointment.person_id) AS "number_of_appointments"
FROM appointment
RIGHT JOIN person ON person.person_id = appointment.person_id
GROUP BY person.person_id;

This just builds on the selected answer, but as the outer join is in the RIGHT direction, only one word needs to be added and less changes. - Just remember that it's there and can sometimes make queries more readable and require less rebuilding.

Here is my really simple solution. Use the gmatch function to capture strings which contain at least one character of anything other than the desired separator. The separator is **any* whitespace (%s in Lua) by default:

function mysplit (inputstr, sep)
        if sep == nil then
                sep = "%s"
        end
        local t={}
        for str in string.gmatch(inputstr, "([^"..sep.."]+)") do
                table.insert(t, str)
        end
        return t
end

.

As you are using asp:Button which is a server control, post back will happen to avoid that go for html button,

I found a way if you're going across classes and want the class the method belongs to AND the method. It takes a bit of extraction work but it makes its point. This works in Python 2.7.13.

import inspect, os

class ClassOne:
    def method1(self):
        classtwoObj.method2()

class ClassTwo:
    def method2(self):
        curframe = inspect.currentframe()
        calframe = inspect.getouterframes(curframe, 4)
        print '\nI was called from', calframe[1][3], \
        'in', calframe[1][4][0][6: -2]

# create objects to access class methods
classoneObj = ClassOne()
classtwoObj = ClassTwo()

# start the program
os.system('cls')
classoneObj.method1()

A cast, as Blaz Bratanic suggested:

size_t data = 99999999;
int convertdata = static_cast<int>(data);

is likely to silence the warning (though in principle a compiler can warn about anything it likes, even if there's a cast).

But it doesn't solve the problem that the warning was telling you about, namely that a conversion from size_t to int really could overflow.

If at all possible, design your program so you don't need to convert a size_t value to int. Just store it in a size_t variable (as you've already done) and use that.

Converting to double will not cause an overflow, but it could result in a loss of precision for a very large size_t value. Again, it doesn't make a lot of sense to convert a size_t to a double; you're still better off keeping the value in a size_t variable.

(R Sahu's answer has some suggestions if you can't avoid the cast, such as throwing an exception on overflow.)

You do not need to use substring at all since your format doesn't hold that info.

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";  
Date fechaNueva = format.parse(fechaStr);

System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29

You can use this:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)" 

to install homebrew.

I have read all answers, but this link was more clear explanation for me about difference between CPU(Processor) and Core. So I'm leaving here some notes from there.

The main difference between CPU and Core is that the CPU is an electronic circuit inside the computer that carries out instruction to perform arithmetic, logical, control and input/output operations while the core is an execution unit inside the CPU that receives and executes instructions.

Building on and updating a number of earlier responses (thanks: SilentGhost, nosklo, Ramkumar) a simple portable timer would use timeit's default_timer():

>>> import timeit
>>> tic=timeit.default_timer()
>>> # Do Stuff
>>> toc=timeit.default_timer()
>>> toc - tic #elapsed time in seconds

This will return the elapsed wall clock (real) time, not CPU time. And as described in the timeit documentation chooses the most precise available real-world timer depending on the platform.

ALso, beginning with Python 3.3 this same functionality is available with the time.perf_counter performance counter. Under 3.3+ timeit.default_timer() refers to this new counter.

For more precise/complex performance calculations, timeit includes more sophisticated calls for automatically timing small code snippets including averaging run time over a defined set of repetitions.

FileReader reads from files on the file system.

Perhaps you intended to use something like this to load a file from the class path

// this will look in src/main/resources before building and myjar.jar! after building.
InputStream is = MyClass.class.getClassloader()
                     .getResourceAsStream("config.txt");

Or you could extract the file from the jar before reading it.

Enter the submodule directory:

cd projB/projA

Pull the repo from you project A (will not update the git status of your parent, project B):

git pull origin master

Go back to the root directory & check update:

cd ..
git status

If the submodule updated before, it will show something like below:

# Not currently on any branch.
# Changed but not updated:
#   (use "git add ..." to update what will be committed)
#   (use "git checkout -- ..." to discard changes in working directory)
#
#       modified:   projB/projA (new commits)
#

Then, commit the update:

git add projB/projA
git commit -m "projA submodule updated"

UPDATE

As @paul pointed out, since git 1.8, we can use

git submodule update --remote --merge

to update the submodule to the latest remote commit. It'll be convenient in most cases.

Where have you specified the mapping code (CreateMap)? Reference: Where do I configure AutoMapper?

If you're using the static Mapper method, configuration should only happen once per AppDomain. That means the best place to put the configuration code is in application startup, such as the Global.asax file for ASP.NET applications.

If the configuration isn't registered before calling the Map method, you will receive Missing type map configuration or unsupported mapping.

In my case it is working as expected for all browsers after setting time interval.

setTimeout(function(){document.location.href = "myNextPage.html;"},100);

 >>> sorted(['Some', 'words', 'sort', 'differently'], key=lambda word: word.lower())

Actually, above codes can be:

>>> sorted(['Some','words','sort','differently'],key=str.lower)

According to https://docs.python.org/2/library/functions.html?highlight=sorted#sorted, key specifies a function of one argument that is used to extract a comparison key from each list element: key=str.lower. The default value is None (compare the elements directly).

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

Step by step:
1. pip install chromedriver-binary
2. import the package

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

Reference: https://pypi.org/project/chromedriver-binary/

I can confirm that the maximum can be slightly over 3200. I'm getting up to 3231 right now.

Gilean's answer is great, but I just wanted to add that sometimes there are rare exceptions to best practices, and you might want to test your environment both ways to see what will work best.

In one case, I found that query worked faster for my purposes because I was bulk transferring trusted data from an Ubuntu Linux box running PHP7 with the poorly supported Microsoft ODBC driver for MS SQL Server.

I arrived at this question because I had a long running script for an ETL that I was trying to squeeze for speed. It seemed intuitive to me that query could be faster than prepare & execute because it was calling only one function instead of two. The parameter binding operation provides excellent protection, but it might be expensive and possibly avoided if unnecessary.

Given a couple rare conditions:

1. If you can't reuse a prepared statement because it's not supported by the Microsoft ODBC driver.

2. If you're not worried about sanitizing input and simple escaping is acceptable. This may be the case because binding certain datatypes isn't supported by the Microsoft ODBC driver.

3. PDO::lastInsertId is not supported by the Microsoft ODBC driver.

Here's a method I used to test my environment, and hopefully you can replicate it or something better in yours:

To start, I've created a basic table in Microsoft SQL Server

CREATE TABLE performancetest (
    sid INT IDENTITY PRIMARY KEY,
    id INT,
    val VARCHAR(100)
);

And now a basic timed test for performance metrics.

$logs = [];

$test = function (String $type, Int $count = 3000) use ($pdo, &$logs) {
    $start = microtime(true);
    $i = 0;
    while ($i < $count) {
        $sql = "INSERT INTO performancetest (id, val) OUTPUT INSERTED.sid VALUES ($i,'value $i')";
        if ($type === 'query') {
            $smt = $pdo->query($sql);
        } else {
            $smt = $pdo->prepare($sql);
            $smt ->execute();
        }
        $sid = $smt->fetch(PDO::FETCH_ASSOC)['sid'];
        $i++;
    }
    $total = (microtime(true) - $start);
    $logs[$type] []= $total;
    echo "$total $type\n";
};

$trials = 15;
$i = 0;
while ($i < $trials) {
    if (random_int(0,1) === 0) {
        $test('query');
    } else {
        $test('prepare');
    }
    $i++;
}

foreach ($logs as $type => $log) {
    $total = 0;
    foreach ($log as $record) {
        $total += $record;
    }
    $count = count($log);
    echo "($count) $type Average: ".$total/$count.PHP_EOL;
}

I've played with multiple different trial and counts in my specific environment, and consistently get between 20-30% faster results with query than prepare/execute

5.8128969669342 prepare
5.8688418865204 prepare
4.2948560714722 query
4.9533629417419 query
5.9051351547241 prepare
4.332102060318 query
5.9672858715057 prepare
5.0667371749878 query
3.8260300159454 query
4.0791549682617 query
4.3775160312653 query
3.6910600662231 query
5.2708210945129 prepare
6.2671611309052 prepare
7.3791449069977 prepare
(7) prepare Average: 6.0673267160143
(8) query Average: 4.3276024162769

I'm curious to see how this test compares in other environments, like MySQL.

try:
    parts = ip.split('.')
    return len(parts) == 4 and all(0 <= int(part) < 256 for part in parts)
except ValueError:
    return False # one of the 'parts' not convertible to integer
except (AttributeError, TypeError):
    return False # `ip` isn't even a string

You can use reflection (reflect.TypeOf()) to get the type of something, and the value it gives (Type) has a string representation (String method) that you can print.

You can also use:

$ sudo gem install rvm

It should give you the following output:

Fetching: rvm-1.11.3.9.gem (100%)
Successfully installed rvm-1.11.3.9
Parsing documentation for rvm-1.11.3.9
Installing ri documentation for rvm-1.11.3.9
1 gem installed

You pass them in just like you're thinking, and in your script, you get them from the array @ARGV. Like so:

my $numArgs = $#ARGV + 1;
print "thanks, you gave me $numArgs command-line arguments.\n";

foreach my $argnum (0 .. $#ARGV) {

   print "$ARGV[$argnum]\n";

}

From here.

This can be accomplished by Unmarshaling into a map[string]json.RawMessage.

var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)

To further parse sendMsg, you could then do something like:

var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)

For say, you can do the same thing and unmarshal into a string:

var str string
err = json.Unmarshal(objmap["say"], &str)

EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:

type sendMsg struct {
    User string
    Msg  string
}

Example: https://play.golang.org/p/OrIjvqIsi4-

Use:

SCRIPT_PATH=$(dirname `which $0`)

which prints to standard output the full path of the executable that would have been executed when the passed argument had been entered at the shell prompt (which is what $0 contains)

dirname strips the non-directory suffix from a file name.

Hence you end up with the full path of the script, no matter if the path was specified or not.

The one liner : bind() to own address, connect() to remote address.

Quoting from the man page of bind()

bind() assigns the address specified by addr to the socket referred to by the file descriptor sockfd. addrlen specifies the size, in bytes, of the address structure pointed to by addr. Traditionally, this operation is called "assigning a name to a socket".

and, from the same for connect()

The connect() system call connects the socket referred to by the file descriptor sockfd to the address specified by addr.

To clarify,

• bind() associates the socket with its local address [that's why server side binds, so that clients can use that address to connect to server.]
• connect() is used to connect to a remote [server] address, that's why is client side, connect [read as: connect to server] is used.

You have your print() statement in the for() loop, It should be after so that it only prints once. the way it currently is, every time the max changes it prints a max.

According to the documentation, use a relative path for a local jar dependency as follows:

dependencies {
    implementation files('libs/something_local.jar')
}

Hello I have written a code for drawing a circle. It will help for drawing all kind of circles. The image shows the circle with radius 1 and center at 0,0 The center and radius can be edited of any choice.

## Draw a circle with center and radius defined
## Also enable the coordinate axes
import matplotlib.pyplot as plt
import numpy as np
# Define limits of coordinate system
x1 = -1.5
x2 = 1.5
y1 = -1.5
y2 = 1.5

circle1 = plt.Circle((0,0),1, color = 'k', fill = False, clip_on = False)
fig, ax = plt.subplots()
ax.add_artist(circle1)
plt.axis("equal")
ax.spines['left'].set_position('zero')
ax.spines['bottom'].set_position('zero')
ax.spines['right'].set_color('none')
ax.spines['top'].set_color('none')
ax.xaxis.set_ticks_position('bottom')
ax.yaxis.set_ticks_position('left')
plt.xlim(left=x1)
plt.xlim(right=x2)
plt.ylim(bottom=y1)
plt.ylim(top=y2)
plt.axhline(linewidth=2, color='k')
plt.axvline(linewidth=2, color='k')

##plt.grid(True)
plt.grid(color='k', linestyle='-.', linewidth=0.5)
plt.show()

Good luck

Since **kwargs is used when the number of arguments is unknown, why not doing this?

class Exampleclass(object):
  def __init__(self, **kwargs):
    for k in kwargs.keys():
       if k in [acceptable_keys_list]:
          self.__setattr__(k, kwargs[k])

In my case, everything was set up correctly, but my Docker infrastructure needed more RAM. I'm using Docker for Mac, where default RAM was around 1 GB, and as MySQL uses around 1.5Gb of RAM ( and probably was crashing ??? ), changing the Docker RAM utilization level to 3-4 Gb solved the issue.

use this command php artisan migrate --path=/database/migrations/my_migration.php it worked for me..

If you want to exit from your application. Then use this code inside your button pressed event. like:

public void onBackPressed()
{
    moveTaskToBack(true);
    android.os.Process.killProcess(android.os.Process.myPid());
    System.exit(1);
}

OK the main difference between class methods and static methods is:

• class method has its own identity, that's why they have to be called from within an INSTANCE.
• on the other hand static method can be shared between multiple instances so that it must be called from within THE CLASS

With a small change, it worked fine for me

$qb=$this->dm->createQueryBuilder('AppBundle:CSSDInstrument')
               ->update()
               ->field('status')->set($status)
               ->field('id')->equals($instrumentId)
               ->getQuery()
               ->execute();

The jQueryUI provides a extension to animate function that allows you to animate css class.

edit: Example here

There are also methods to add/remove/toggle class which you might also be interested in.

The support for stored procedure in EF Core is similar to the earlier versions of EF Code first.

You need to create your DbContext class by inherting the DbContext class from EF. The stored procedures are executing using the DbContext.

First step is to write a method that create a DbCommand from the DbContext.

public static DbCommand LoadStoredProc(
  this DbContext context, string storedProcName)
{
  var cmd = context.Database.GetDbConnection().CreateCommand();
  cmd.CommandText = storedProcName;
  cmd.CommandType = System.Data.CommandType.StoredProcedure;
  return cmd;
}

To pass parameters to the stored procedure use the following method.

public static DbCommand WithSqlParam(
  this DbCommand cmd, string paramName, object paramValue)
{
  if (string.IsNullOrEmpty(cmd.CommandText))
    throw new InvalidOperationException(
      "Call LoadStoredProc before using this method");
  var param = cmd.CreateParameter();
  param.ParameterName = paramName;
  param.Value = paramValue;
  cmd.Parameters.Add(param);
  return cmd;
}

Finally for mapping the result into a list of custom objects use the MapToList method.

private static List<T> MapToList<T>(this DbDataReader dr)
{
  var objList = new List<T>();
  var props = typeof(T).GetRuntimeProperties();

  var colMapping = dr.GetColumnSchema()
    .Where(x => props.Any(y => y.Name.ToLower() == x.ColumnName.ToLower()))
    .ToDictionary(key => key.ColumnName.ToLower());

  if (dr.HasRows)
  {
    while (dr.Read())
    {
      T obj = Activator.CreateInstance<T>();
      foreach (var prop in props)
      {
        var val = 
          dr.GetValue(colMapping[prop.Name.ToLower()].ColumnOrdinal.Value);
          prop.SetValue(obj, val == DBNull.Value ? null : val);
      }
      objList.Add(obj);
    }
  }
  return objList;
}

Now we’re ready for execute the stored procedute with the ExecuteStoredProc method and maps it to the a List whose type that’s passed in as T.

public static async Task<List<T>> ExecuteStoredProc<T>(this DbCommand command)
{
  using (command)
  {
    if (command.Connection.State == System.Data.ConnectionState.Closed)
    command.Connection.Open();
    try
    {
      using (var reader = await command.ExecuteReaderAsync())
      {
        return reader.MapToList<T>();
      }
    }
    catch(Exception e)
    {
      throw (e);
    }
    finally
    {
      command.Connection.Close();
    }
  }
}

For example, to execute a stored procedure called “StoredProcedureName” with two parameters called “firstparamname” and “secondparamname” this is the implementation.

List<MyType> myTypeList = new List<MyType>();
using(var context = new MyDbContext())
{
  myTypeList = context.LoadStoredProc("StoredProcedureName")
  .WithSqlParam("firstparamname", firstParamValue)
  .WithSqlParam("secondparamname", secondParamValue).
  .ExecureStoredProc<MyType>();
}

The following function adds months to a date in JavaScript (source). It takes into account year roll-overs and varying month lengths:

function addMonths(date, months) {_x000D_
    var d = date.getDate();_x000D_
    date.setMonth(date.getMonth() + +months);_x000D_
    if (date.getDate() != d) {_x000D_
      date.setDate(0);_x000D_
    }_x000D_
    return date;_x000D_
}_x000D_
_x000D_
// Add 12 months to 29 Feb 2016 -> 28 Feb 2017_x000D_
console.log(addMonths(new Date(2016,1,29),12).toString());_x000D_
_x000D_
// Subtract 1 month from 1 Jan 2017 -> 1 Dec 2016_x000D_
console.log(addMonths(new Date(2017,0,1),-1).toString());_x000D_
_x000D_
// Subtract 2 months from 31 Jan 2017 -> 30 Nov 2016_x000D_
console.log(addMonths(new Date(2017,0,31),-2).toString());_x000D_
_x000D_
// Add 2 months to 31 Dec 2016 -> 28 Feb 2017_x000D_
console.log(addMonths(new Date(2016,11,31),2).toString());

The above solution covers the edge case of moving from a month with a greater number of days than the destination month. eg.

• Add twelve months to February 29th 2020 (should be February 28th 2021)
• Add one month to August 31st 2020 (should be September 30th 2020)

If the day of the month changes when applying setMonth, then we know we have overflowed into the following month due to a difference in month length. In this case, we use setDate(0) to move back to the last day of the previous month.

Note: this version of this answer replaces an earlier version (below) that did not gracefully handle different month lengths.

var x = 12; //or whatever offset
var CurrentDate = new Date();
console.log("Current date:", CurrentDate);
CurrentDate.setMonth(CurrentDate.getMonth() + x);
console.log("Date after " + x + " months:", CurrentDate);

Inline code takes higher precedence than the other ones. To call your other function func () call it from the f1 ().

Inside your function, add a line,

function fun () {
// Your code here
}

function f1()
    {
       alert("f1 called");
       //form validation that recalls the page showing with supplied inputs.    

fun ();

    }

Rewriting your whole code,

 <!DOCTYPE html>
    <html>
      <head>

      <script>

       function fun()
        {
         alert("hello");
         //validation code to see State field is mandatory.  
        }   

        function f1()
        {
           alert("f1 called");
           //form validation that recalls the page showing with supplied inputs.   
           fun (); 
        }

      </script>
      </head>
      <body>
       <form name="form1" id="form1" method="post">

         State: <select id="state ID">
                   <option></option>
                   <option value="ap">ap</option>
                   <option value="bp">bp</option>
                </select>
       </form>
       <table><tr><td id="Save" onclick="f1()">click</td></tr></table>

      </body>
</html>

1. Open file nodevars.bat
2. Just add your path to the end, "%HOMEDRIVE%%HOMEPATH% /file1/file2/file3
3. Save file nodevars.bat

This work even with Swedish words

BigDataCloud also has a nice API for this, also for nodejs users.

they have API for client - free. But also for backend, using API_KEY (free according to quota).

Their GitHub page.

the code looks like:

const client = require('@bigdatacloudapi/client')(API_KEY);

async foo() {
    ...
    const location: string = await client.getReverseGeocode({
          latitude:'32.101786566878445', 
          longitude: '34.858965073072056'
    });
}

Why don't you use PowerShell?

Stop-Process -Name notepad

And if you are in a batch file:

powershell -Command "Stop-Process -Name notepad"
powershell -Command "Stop-Process -Id 4232"

To sum up all the brilliant points of chrispy, Skurmedel, Ben Hoyt and Peter Hansen, this would be the optimal solution for processing a binary file one byte at a time:

with open("myfile", "rb") as f:
    while True:
        byte = f.read(1)
        if not byte:
            break
        do_stuff_with(ord(byte))

For python versions 2.6 and above, because:

• python buffers internally - no need to read chunks
• DRY principle - do not repeat the read line
• with statement ensures a clean file close
• 'byte' evaluates to false when there are no more bytes (not when a byte is zero)

Or use J. F. Sebastians solution for improved speed

from functools import partial

with open(filename, 'rb') as file:
    for byte in iter(partial(file.read, 1), b''):
        # Do stuff with byte

Or if you want it as a generator function like demonstrated by codeape:

def bytes_from_file(filename):
    with open(filename, "rb") as f:
        while True:
            byte = f.read(1)
            if not byte:
                break
            yield(ord(byte))

# example:
for b in bytes_from_file('filename'):
    do_stuff_with(b)

A lone print will output a newline.

print

In 3.x print is a function, therefore:

print()

if you want to stay DRY, use an include.

{% if foo %}
  {% with a as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% else %}
  {% with bar as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% endif %}

or, even better would be to write a method on the model that encapsulates the core logic:

def Patient(models.Model):
    ....
    def get_legally_responsible_party(self):
       if self.age > 18:
          return self
       else:
          return self.parent

Then in the template:

{% with patient.get_legally_responsible_party as p %}
  Do html stuff
{% endwith %} 

Then in the future, if the logic for who is legally responsible changes you have a single place to change the logic -- far more DRY than having to change if statements in a dozen templates.

Workaround: We need to call the callback functions (Task and Anonymous):

function electronTask(callbackA)
{
    return gulp.series(myFirstTask, mySeccondTask, (callbackB) =>
    {
        callbackA();
        callbackB();
    })();    
}

I know you said you would prefer a GUI, but the commandline tools will do the work nicely. See GnuWin for a port of unix tools to Windows. You'd need the patch command, obviously ;-)

You might run into a problem with the line termination, though. The GnuWin port will assume that the patchfile has DOS style line termination (CR/LF). Try to open the patchfile in a reasonably smart editor and it will convert it for you.

Previous answers advise using the tarfile Python module for creating a .tar.gz file in Python. That's obviously a good and Python-style solution, but it has serious drawback in speed of the archiving. This question mentions that tarfile is approximately two times slower than the tar utility in Linux. According to my experience this estimation is pretty correct.

So for faster archiving you can use the tar command using subprocess module:

subprocess.call(['tar', '-czf', output_filename, file_to_archive])

I am using Windows 8.1 environment. I had the same problem while running my first java program after installing Eclipse recently. I had installed java on d drive at d:\java. But Eclipse was looking at the default installation c:\programfiles\java. I did the following:

1. Modified my eclipse.ini file and added the following after open:

   -vm
   d:\java\jdk1.8.0_161\bin 
   

2. While creating the java program I have to unselect default build path and then select d:\java.

After this, the program ran well and got the hello world to work.

This is working for me, as described in this thread:

declare let something: string;
something = 'foo';

Are you trying to remove a single value or all matching values?

If you are trying to remove a single value, how do you define the value you wish to remove?

The reason you don't get a key back when querying on values is because the dictionary could contain multiple keys paired with the specified value.

If you wish to remove all matching instances of the same value, you can do this:

foreach(var item in dic.Where(kvp => kvp.Value == value).ToList())
{
    dic.Remove(item.Key);
}

And if you wish to remove the first matching instance, you can query to find the first item and just remove that:

var item = dic.First(kvp => kvp.Value == value);

dic.Remove(item.Key);

Note: The ToList() call is necessary to copy the values to a new collection. If the call is not made, the loop will be modifying the collection it is iterating over, causing an exception to be thrown on the next attempt to iterate after the first value is removed.

A less verbose approach:

int number = [dict[@"integer"] intValue];

you can use

var FirstString = YourString.Split().First();

to split string .

You need to use the android:background property , eg

android:background="@color/white"

Also you need to add a value for white in the strings.xml

<color name="white">#FFFFFF</color>

Edit : 18th Nov 2012

The first two letters of an 8 letter color code provide the alpha value, if you are using the html 6 letter color notation the color is opaque.

Eg :

According to IE 9 – What’s Changed? on the HttpWatch blog, IE9 still has a 2 connection limit when over VPN.

Using a VPN Still Clobbers IE 9 Performance

We previously reported about the scaling back of the maximum number of concurrent connections in IE 8 when your PC uses a VPN connection. This happened even if the browser traffic didn’t go over that connection.

Unfortunately, IE 9 is affected by VPN connections in the same way:

What did work for me (inspired from aax' thanks) :

Paste this into /Library/LaunchDaemons/com.apple.launchd.limit.plist then reboot :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
  <plist version="1.0">
  <dict>
  <key>Label</key>
  <string>eicar</string>
  <key>ProgramArguments</key>
  <array>
    <string>/bin/launchctl</string>
    <string>limit</string>
    <string>maxfiles</string>
    <string>16384</string>
    <string>16384</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>ServiceIPC</key>
  <false/>
</dict>
</plist>

If you need it step by step :

• Launch terminal
• Type sudo su then enter your password to log in as root
• Type vi /Library/LaunchDaemons/com.apple.launchd.limit.plist
• When into the vi editor, press the key i to enter insert mode then paste the exact code content above (?+v). This will force the limit to 16384 files per process and 16384 files total
• Save your file and quit using esc then :wq
• Reboot your system, and check that it is working using the command launchctl limit

I hope this helped you.

Duplicate question which basically says use ExecuteScalar() instead.

As far as I remember there is an xml element for the image data. You can use this website to encode a file (use the upload field). Then just copy and paste the data to the XML element.

You could also use PHP to do this like so:

 <?php
        $im = file_get_contents('filename.gif');
        $imdata = base64_encode($im);      
?> 

Use Mozilla's guide for help on creating OpenSearch plugins. For example, the icon element is used like this:

<img width="16" height="16">data:image/x-icon;base64,imageData</>

Where imageData is your base64 data.

I needed to capture both stdout and stderr and have it timeout if the process didn't exit when expected. I came up with this:

Process process = new Process();
StringBuilder outputStringBuilder = new StringBuilder();

try
{
process.StartInfo.FileName = exeFileName;
process.StartInfo.WorkingDirectory = args.ExeDirectory;
process.StartInfo.Arguments = args;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.UseShellExecute = false;
process.EnableRaisingEvents = false;
process.OutputDataReceived += (sender, eventArgs) => outputStringBuilder.AppendLine(eventArgs.Data);
process.ErrorDataReceived += (sender, eventArgs) => outputStringBuilder.AppendLine(eventArgs.Data);
process.Start();
process.BeginOutputReadLine();
process.BeginErrorReadLine();
var processExited = process.WaitForExit(PROCESS_TIMEOUT);

if (processExited == false) // we timed out...
{
    process.Kill();
    throw new Exception("ERROR: Process took too long to finish");
}
else if (process.ExitCode != 0)
{
    var output = outputStringBuilder.ToString();
    var prefixMessage = "";

    throw new Exception("Process exited with non-zero exit code of: " + process.ExitCode + Environment.NewLine + 
    "Output from process: " + outputStringBuilder.ToString());
}
}
finally
{                
process.Close();
}

I am piping the stdout and stderr into the same string, but you could keep it separate if needed. It uses events, so it should handle them as they come (I believe). I have run this successfully, and will be volume testing it soon.

You can also try using apply with get method of dictionary, seems to be little faster than replace:

data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Testing with timeit:

%%timeit
data['sex'].replace([0,1],['Female','Male'],inplace=True)

Result:

The slowest run took 5.83 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 510 µs per loop

Using apply:

%%timeit
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Result:

The slowest run took 5.92 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 331 µs per loop

Note: apply with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.

tell you the true, I still don't get what you need, but

window.location(url);

should be

window.location = url;

a search on window.location reference will tell you that.

MY PREFERRED METHOD is using fopen,fwrite and fclose [it will cost less CPU]

$f=fopen('myfile.txt','w');
fwrite($f,'new content');
fclose($f);

Warning for those using file_put_contents

It'll affect a lot in performance, for example [on the same class/situation] file_get_contents too: if you have a BIG FILE, it'll read the whole content in one shot and that operation could take a long waiting time

I tried solving this problem for hours after I haven't used Android Studio some time and wasn't aware of the updates.

It is important that google() is the first item that stands in repositories like this:

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

Somehow google() was the second item after jcenter(), so everything was messed up and didn't work. Maybe this helps someone.

long d1Ms=asa.getTime();   
long d2Ms=asa2.getTime();   
long minute = Math.abs((d1Ms-d2Ms)/60000);   
int Hours = (int)minute/60;     
int Minutes = (int)minute%60;     
stUr.setText(Hours+":"+Minutes); 

If you look at the code for the component you can see that it uses the className prop passed to it to combine with the row class to get the resulting set of classes (<Row className="aaa bbb"... works).Also, if you provide the id prop like <Row id="444" ... it will actually set the id attribute for the element.

Here are a couple possible solutions...

I have not tried all of these myself yet, but I will be trying them all soon.

Note: I do not have any personal or financial connection to any of these tools.

1) VB Script to EXE Converter (NOT Compiler): (Free)
vbs2exe.com.

The exe produced appears to be a true EXE.

From their website:

VBS to EXE is a free online converter that doesn't only convert your vbs files into exe but it also:

1- Encrypt your vbs file source code using 128 bit key.
2- Allows you to call win32 API
3- If you have troubles with windows vista especially when UAC is enabled then you may give VBS to EXE a try.
4- No need for wscript.exe to run your vbs anymore.
5- Your script is never saved to the hard disk like some others converters. it is a TRUE exe not an extractor.

This solution should work even if wscript/cscript is not installed on the computer.

Basically, this creates a true .EXE file. Inside the created .EXE is an "engine" that replaces wscript/cscript, and an encrypted copy of your VB Script code. This replacement engine executes your code IN MEMORY without calling wscript/cscript to do it.

2) Compile and Convert VBS to EXE...:
ExeScript

The current version is 3.5.

This is NOT a Free solution. They have a 15 day trial. After that, you need to buy a license for a hefty $44.96 (Home License/noncommercial), or $89.95 (Business License/commercial usage).

It seems to work in a similar way to the previous solution.

According to a forum post there:
Post: "A Exe file still need Windows Scripting Host (WSH) ??"

WSH is not required if "Compile" option was used, since ExeScript
implements it's own scripting host. ...

3) Encrypt the script with Microsoft's ".vbs to .vbe" encryption tool.

Apparently, this does not work for Windows 7/8, and it is possible there are ways to "decrypt" the .vbe file. At the time of writing this, I could not find a working link to download this. If I find one, I will add it to this answer.

No need to apply anything. Just add this code at the end of variable to which date is assigned. For example

   @todaydate = "2011-05-19 10:30:14"
   @todaytime.to_time.strftime('%a %b %d %H:%M:%S %Z %Y')

You will get proper format as you like. You can check this at Rails Console

Loading development environment (Rails 3.0.4)
ruby-1.9.2-p136 :001 > todaytime = "2011-05-19 10:30:14"
 => "2011-05-19 10:30:14" 
ruby-1.9.2-p136 :002 > todaytime
 => "2011-05-19 10:30:14" 
ruby-1.9.2-p136 :003 > todaytime.to_time
 => 2011-05-19 10:30:14 UTC
ruby-1.9.2-p136 :008 > todaytime.to_time.strftime('%a %b %d %H:%M:%S %Z %Y')
 => "Thu May 19 10:30:14 UTC 2011"

Try 'date_format' gem to show date in different format.

git stash is your friend.

If you have not made the commit yet, just run git stash. This will save away all of your changes.

Switch to the branch you want the changes on and run git stash pop.

There are lots of uses for git stash. This is certainly one of the more useful reasons.

An example:

# work on some code
git stash
git checkout correct-branch
git stash pop

Just go to Android device monitor from Android studio , then DDMS -> Emulator Control.There will be Speed and Latency properties.

From API 21 `getDrawable(int id)` is deprecated

So now you need to use

ResourcesCompat.getDrawable(context.getResources(), R.drawable.img_user, null)

But Best way to do is :

object ResourceUtils {
    fun getColor(context: Context, color: Int): Int {
        return ResourcesCompat.getColor(context.getResources(), color, null)
    }

    fun getDrawable(context: Context, drawable: Int): Drawable? {
        return ResourcesCompat.getDrawable(context.getResources(), drawable, null)
    }
}

use this method like :

Drawable img=ResourceUtils.getDrawable(context, R.drawable.img_user)
image.setImageDrawable(img);

With the release of TypeScript 3.7, optional chaining (the ? operator) is now officially available.

As such, you can simplify your expression to the following:

const data = change?.after?.data();

You may read more about it from that version's release notes, which cover other interesting features released on that version.

Run the following to install the latest stable release of TypeScript.

npm install typescript

That being said, Optional Chaining can be used alongside Nullish Coalescing to provide a fallback value when dealing with null or undefined values

const data = change?.after?.data() ?? someOtherData();

The REAL REAL answer is: For API 21 and higher:

No java code needed. You can set android:nestedScrollingEnabled="false" in xml:

<android.support.v7.widget.RecyclerView
     android:id="@+id/recycler"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:clipToPadding="true"
     android:nestedScrollingEnabled="false"
     tools:listitem="@layout/adapter_favorite_place">

I will rather recommend Mage2Gen, this will help you generate the boilerplate and you can just focus on the core business logic. it just helps speed up the things.

A simple solution to this problem is to return from the render loop if the frame is not required to render:

const FPS = 60;
let prevTick = 0;    

function render() 
{
    requestAnimationFrame(render);

    // clamp to fixed framerate
    let now = Math.round(FPS * Date.now() / 1000);
    if (now == prevTick) return;
    prevTick = now;

    // otherwise, do your stuff ...
}

It's important to know that requestAnimationFrame depends on the users monitor refresh rate (vsync). So, relying on requestAnimationFrame for game speed for example will make it unplayable on 200Hz monitors if you're not using a separate timer mechanism in your simulation.

I doubt if any of those should work. Try: First import the namespace in the beginning of the code page as below.

using System.Drawing;

then in the code.

Button4.BackColor = Color.LawnGreen;

Hope it helps.

You should use val instead of value.

<script type="text/javascript" language="javascript">
$(document).ready(function () { 
    $('input[name="testing"]').val('Work!');
});
</script>

I am a big fan of DB4O for both .Net and Java.

Performance has become much better since the early releases. The licensing model isnt too bad, either. I particularly like the options available for querying your objects. Query by example is very powerful and easy to get used to.

I was wondering why my class' destructor was not called. The reason was that I had forgot to include definition of that class (#include "class.h"). I only had a declaration like "class A;" and the compiler was happy with it and let me call "delete".

Here is another way to convert Drawable resource into Bitmap in android:

Drawable drawable = getResources().getDrawable(R.drawable.input);
Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();

Old question but here's the code on how to do what you are asking. In this case I am passing data from a selected cell in a table view to another view controller.

in the .h file of the trget view:

@property(weak, nonatomic)  NSObject* dataModel;

in the .m file:

@synthesize dataModel;

dataModel can be string, int, or like in this case it's a model that contains many items

- (void)someMethod {
     [self performSegueWithIdentifier:@"loginMainSegue" sender:self];
 }

OR...

- (void)someMethod {
    UIViewController *myController = [self.storyboard instantiateViewControllerWithIdentifier:@"HomeController"];
    [self.navigationController pushViewController: myController animated:YES];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if([segue.identifier isEqualToString:@"storyDetailsSegway"]) {
        UITableViewCell *cell = (UITableViewCell *) sender;
        NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
        NSDictionary *storiesDict =[topStories objectAtIndex:[indexPath row]];
        StoryModel *storyModel = [[StoryModel alloc] init];
        storyModel = storiesDict;
        StoryDetails *controller = (StoryDetails *)segue.destinationViewController;
        controller.dataModel= storyModel;
    }
}

Don'y forget that if you are mixing grouped (ie. SUM) fields and non-grouped fields, you need to GROUP BY one of the non-grouped fields.

Try this:

SELECT SUM(something) AS fieldname
FROM tablename
ORDER BY fieldname

OR this:

SELECT Field1, SUM(something) AS Field2
FROM tablename
GROUP BY Field1
ORDER BY Field2

And you can always do a derived query like this:

SELECT
   f1, f2
FROM
    (
        SELECT SUM(x+y) as f1, foo as F2
        FROM tablename 
        GROUP BY f2
    ) as table1
ORDER BY 
    f1

Many possibilities!

It's generally considered a bad idea to ignore exceptions. Usually, if it's appropriate, you want to either notify the user of the issue (if they would care) or at the very least, log the exception, or print the stack trace to the console.

However, if that's truly not necessary (you're the one making the decision) then no, there's no other way to ignore an exception that forces you to catch it. The only revision, in that case, that I would suggest is explicitly listing the the class of the Exceptions you're ignoring, and some comment as to why you're ignoring them, rather than simply ignoring any exception, as you've done in your example.

Pattern class is the entry point of the regex engine.You can use it through Pattern.matches() and Pattern.comiple(). #Difference between these two. matches()- for quickly check if a text (String) matches a given regular expression comiple()- create the reference of Pattern. So can use multiple times to match the regular expression against multiple texts.

For reference:

public static void main(String[] args) {
     //single time uses
     String text="The Moon is far away from the Earth";
     String pattern = ".*is.*";
     boolean matches=Pattern.matches(pattern,text);
     System.out.println("Matches::"+matches);

    //multiple time uses
     Pattern p= Pattern.compile("ab");
     Matcher  m=p.matcher("abaaaba");
     while(m.find()) {
         System.out.println(m.start()+ " ");
     }
}

Return output first true value.

If all are false return last false value.

Example:-

  null || undefined || false || 0 || 'apple'  // Return apple

The following command will give you the list of files that the gem package installed:

dpkg -L gem

that should help you troubleshoot.

Please change your code like below.

  int QuestionID;

  bool IsIntValue = Int32.TryParse("YOUR-VARIABLE", out QuestionID);

  if (IsIntValue)
  {
      // YOUR CODE HERE  
  }

Hope i will be help.

I found the answer in this command:

docker images --no-trunc | grep none | awk '{print $3}' | xargs docker rmi

I had your problem when I deleted some images that were being used, and I didn't realise (using docker ps -a).

The answers abow didnt really work for me, i had a click event on the wrapper and ie 7,8,9,10 ignored the z-index, so my fix was giving the wrapper a background-color and it all of a sudden worked. Al though it was suppose to be transparent, so i defined the wrapper with the background-color white, and then opacity 0.01, and now it works. I also have the functions above, so it could be a combination.

I dont know why it works, im just happy it does.

Not exactly the case of actual context of this question, but this exception can be reproduced by the next query:

update users set dismissal_reason='he can't and don't want' where userid=123

Single quotes in words can't and don't broke the string. In case string have only one inside quote e.g. 'he don't want' oracle throws more relevant quoted string not properly terminated error, but in case of two SQL command not properly ended is thrown.

Summary: check your query for double single quotes.

Before you begin to curse your application you need to check this:

1. Is your application the only one using that instance of SQL Server. a. If the answer to that is NO then you need to investigate how the other applications are consuming resources on your SQl Server.run b. If the answer is yes then you must investigate your application.

2. Run SQL Server Profiler and check what activity is happening in other applications (1a) using SQL Server and check your application as well (1b).

3. If indeed your application is starved off of resources then you need to make farther investigations. For more read on this http://sqlserverplanet.com/troubleshooting/sql-server-slowness

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

If you need the numeric values, here's the quickest way:

dog, cat, rabbit = range(3)

In Python 3.x you can also add a starred placeholder at the end, which will soak up all the remaining values of the range in case you don't mind wasting memory and cannot count:

dog, cat, rabbit, horse, *_ = range(100)

After some research and testing, I found that I had some misunderstandings about the lifetime of Docker containers. Simply restarting a container doesn't make Docker use a new image, when the image was rebuilt in the meantime. Instead, Docker is fetching the image only before creating the container. So the state after running a container is persistent.

Why removing is required

Therefore, rebuilding and restarting isn't enough. I thought containers works like a service: Stopping the service, do your changes, restart it and they would apply. That was my biggest mistake.

Because containers are permanent, you have to remove them using docker rm <ContainerName> first. After a container is removed, you can't simply start it by docker start. This has to be done using docker run, which itself uses the latest image for creating a new container-instance.

Containers should be as independent as possible

With this knowledge, it's comprehensible why storing data in containers is qualified as bad practice and Docker recommends data volumes/mounting host directorys instead: Since a container has to be destroyed to update applications, the stored data inside would be lost too. This cause extra work to shutdown services, backup data and so on.

So it's a smart solution to exclude those data completely from the container: We don't have to worry about our data, when its stored safely on the host and the container only holds the application itself.

Why -rf may not really help you

The docker run command, has a Clean up switch called -rf. It will stop the behavior of keeping docker containers permanently. Using -rf, Docker will destroy the container after it has been exited. But this switch has two problems:

1. Docker also remove the volumes without a name associated with the container, which may kill your data
2. Using this option, its not possible to run containers in the background using -d switch

While the -rf switch is a good option to save work during development for quick tests, it's less suitable in production. Especially because of the missing option to run a container in the background, which would mostly be required.

How to remove a container

We can bypass those limitations by simply removing the container:

docker rm --force <ContainerName>

The --force (or -f) switch which use SIGKILL on running containers. Instead, you could also stop the container before:

docker stop <ContainerName>
docker rm <ContainerName>

Both are equal. docker stop is also using SIGTERM. But using --force switch will shorten your script, especially when using CI servers: docker stop throws an error if the container is not running. This would cause Jenkins and many other CI servers to consider the build wrongly as failed. To fix this, you have to check first if the container is running as I did in the question (see containerRunning variable).

Full script for rebuilding a Docker container

According to this new knowledge, I fixed my script in the following way:

#!/bin/bash
imageName=xx:my-image
containerName=my-container

docker build -t $imageName -f Dockerfile  .

echo Delete old container...
docker rm -f $containerName

echo Run new container...
docker run -d -p 5000:5000 --name $containerName $imageName

This works perfectly :)

If you're using MySQL Workbench, right-click a table and select alter table.

In that window you can see your table Engine and also change it.

If you want to do this in a single line, try:

Object.keys(a).map(function(key){return a[key]})

You can try this one

class Diacritic
{
    public function replaceDiacritic($input)
    {
        $input = iconv('UTF-8','ASCII//TRANSLIT',$input);
        $input = preg_replace("/['|^|`|~|]/","",$input);
        $input = preg_replace('/["]/','',$input);
        return preg_replace('/[" "]/','_',$input);
    }
}

@Alwin Doss You should provide the -L option before -l. You would have done the other way round probably. Try this :)

This is all i can find out. Not sure if it helps, but thought I'd add it to the mix.

WORD-WRAP

This property specifies whether the current rendered line should break if the content exceeds the boundary of the specified rendering box for an element (this is similar in some ways to the ‘clip’ and ‘overflow’ properties in intent.) This property should only apply if the element has a visual rendering, is an inline element with explicit height/width, is absolutely positioned and/or is a block element.

WORD-BREAK

This property controls the line breaking behavior within words. It is especially useful in cases where multiple languages are used within an element.

What I would do is create a Boolean outside your function that starts out as FALSE and gets set to TRUE when you attach the event. This would serve as some sort of flag for you before you attach the event again. Here's an example of the idea.

// initial load
var attached = false;

// this will only execute code once
doSomething = function()
{
 if (!attached)
 {
  attached = true;
  //code
 }
} 

//attach your function with change event
window.onload = function()
{
 var txtbox = document.getElementById('textboxID');

 if (window.addEventListener)
 {
  txtbox.addEventListener('change', doSomething, false);
 }
 else if(window.attachEvent)
 {
  txtbox.attachEvent('onchange', doSomething);
 }
}

One way to do this is to parse each word of our input string and push it into a LIFO stack.

After whole string is processed, we pop out each word off the stack one by one and append it to a StringBuffer class object, which finally contains the reversed input string.

This is one possible solution in Java using StringTokenizer and Stack class. We need to import java.util.Stack.

public String revString(String input)
{
   StringTokenizer words=new StringTokenizer(input); //Split the string into words
   Stack<String> stack= new Stack<String>();
   while(words.hasMoreTokens())
   {
      stack.push(words.nextElement().toString()); // Push each word of the string onto stack. 
   }
   StringBuilder revString=new StringBuilder();
   while(!stack.empty())
   {
       revString.append(stack.pop()+" ");// pop the top item and append it to revString 
   }
   return revString.toString();
}

Another way to do this is to reassign df based on a cross section of df, using the .xs method.

>>> df

    a
    b   c
0   1   2
1   3   4

>>> df = df.xs('a', axis=1, drop_level=True)

    # 'a' : key on which to get cross section
    # axis=1 : get cross section of column
    # drop_level=True : returns cross section without the multilevel index

>>> df

    b   c
0   1   2
1   3   4

Here's an example which issues the same warning:

import numpy as np
np.seterr(all='warn')
A = np.array([10])
a=A[-1]
a**a

yields

RuntimeWarning: overflow encountered in long_scalars

In the example above it happens because a is of dtype int32, and the maximim value storable in an int32 is 2**31-1. Since 10**10 > 2**32-1, the exponentiation results in a number that is bigger than that which can be stored in an int32.

Note that you can not rely on np.seterr(all='warn') to catch all overflow errors in numpy. For example, on 32-bit NumPy

>>> np.multiply.reduce(np.arange(21)+1)
-1195114496

while on 64-bit NumPy:

>>> np.multiply.reduce(np.arange(21)+1)
-4249290049419214848

Both fail without any warning, although it is also due to an overflow error. The correct answer is that 21! equals

In [47]: import math

In [48]: math.factorial(21)
Out[50]: 51090942171709440000L

According to numpy developer, Robert Kern,

Unlike true floating point errors (where the hardware FPU sets a flag whenever it does an atomic operation that overflows), we need to implement the integer overflow detection ourselves. We do it on the scalars, but not arrays because it would be too slow to implement for every atomic operation on arrays.

So the burden is on you to choose appropriate dtypes so that no operation overflows.

In Bootstrap 4 you can use classes like mt-5, mb-5, my-5, mx-5 (y for both top and bottom, x for both left and right).

According to their site:

The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

Link: https://getbootstrap.com/docs/4.0/utilities/spacing/

If you're using a relatively new version of Python, you can also use a context manager, such as this one:

from __future__ import with_statement
from grizzled.os import working_directory

with working_directory(path_to_directory):
    # code in here occurs within the directory

# code here is in the original directory

UPDATE

If you prefer to roll your own:

import os
from contextlib import contextmanager

@contextmanager
def working_directory(directory):
    owd = os.getcwd()
    try:
        os.chdir(directory)
        yield directory
    finally:
        os.chdir(owd)

Unfortunately the switch option to mount a volume is only found in the run command.

docker run --help

-v, --volume list Bind mount a volume (default [])

There is a way you can work around this though so you won't have to reinstall the applications you've already set up on your container.

1. Export your container docker container export -o ./myimage.docker mycontainer
2. Import as an image docker import ./myimage.docker myimage
3. Then docker run -i -t -v /somedir --name mycontainer myimage /bin/bash

As of powershell 5.0, you can now use the -Depth parameter in Get-ChildItem!

You combine it with -Recurse to limit the recursion.

Get-ChildItem -Recurse -Depth 2

I just switched the main shell to zsh. It suppresses the warnings and it isn't too complicated.

To undo your last commit, simply do git reset --hard HEAD~.

Edit: this answer applied to an earlier version of the question that did not mention preserving local changes; the accepted answer from Tim is indeed the correct one. Thanks to qwertzguy for the heads up.

run

gradle clean 

then try

gradle build 

it worked for me

You'll have to convert it from dps to pixels using the display scale factor.

final float scale = getContext().getResources().getDisplayMetrics().density;
int pixels = (int) (dps * scale + 0.5f);

 Me.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None

If you're using .NET, use the DirectorySearcher class. You can pass in your domain as a string into the constructor.

// if you domain is domain.com...
string username = "user"
string domain = "LDAP://DC=domain,DC=com";
DirectorySearcher search = new DirectorySearcher(domain);
search.Filter = "(SAMAccountName=" + username + ")";

As you can see, 01/01/1970 returns 0, which means it is the lowest possible date.

new Date('1970-01-01Z00:00:00:000') //returns Thu Jan 01 1970 01:00:00 GMT+0100 (Central European Standard Time)
new Date('1970-01-01Z00:00:00:000').getTime() //returns 0
new Date('1970-01-01Z00:00:00:001').getTime() //returns 1

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

I believe this thread hasn't done in particular justice to HBase and Pig in particular. While I believe Hadoop is the choice of the distributed, resilient file-system for big-data lake implementations, the choice between HBase and Hive is in particular well-segregated.

As in, a lot of use-cases have a particular requirement of SQL like or No-SQL like interfaces. With Phoenix on top of HBase, though SQL like capabilities is certainly achievable, however, the performance, third-party integrations, dashboard update are a kind of painful experiences. However, it's an excellent choice for databases requiring horizontal scaling.

Pig is in particular excellent for non-recursive batch like computations or ETL pipelining (somewhere, where it outperforms Spark by a comfortable distance). Also, it's high-level dataflow implementations is an excellent choice for batch querying and scripting. The choice between Pig and Hive is also pivoted on the need of the client or server-side scripting, required file formats, etc. Pig supports Avro file format which is not true in the case of Hive. The choice for 'procedural dataflow language' vs 'declarative data flow language' is also a strong argument for the choice between pig and hive.

I use a mixture of float and overflow-x:hidden. Minimal code, always works.

https://jsfiddle.net/9934sc4d/4/ - PLUS you don't need to clear your float!

.left-half{
    width:200px;
    float:left;
}
.right-half{
    overflow-x:hidden;
}

In order to find an iframe id ending with "iFrame" within a page containing many iframes.

jQuery(document).ready(function (){     
                  jQuery("iframe").each(function(){                     
                    if( jQuery(this).attr('id').match(/_iFrame/) ) {
                            alert(jQuery(this).attr('id'));

                     }                   
                  });     
         });

This is my example

Create a Java Utils

    import android.app.ProgressDialog;

            // ...
            final ProgressDialog progressDialog = ProgressDialog.show(context, "Please wait...", "Loading data ...", true);

            new Thread() {
                public void run() {
                    try{
                        // Do some work here
                        sleep(5000);
                    } catch (Exception e) {
                    }
                    // start next intent
                    new Thread() {
                        public void run() {
                        // Dismiss the Dialog 
                        progressDialog.dismiss();
                        // start selected activity
                        if ( startingIntent != null) context.startActivity(startingIntent);
                        }
                    }.start();
                }
            }.start();  

        }

    }    

Athough it is framework specific, Django 1.4 has this functionailty which works in a similar fashion to the link to the 'greenfelt' site in the above answer

When a thread is executing and you want to execute the main UI thread which is blocked by current thread, then use the below:

current thread:

Dispatcher.CurrentDispatcher.Invoke(MethodName,
    new object[] { parameter1, parameter2 }); // if passing 2 parameters to method.

Main UI thread:

Application.Current.Dispatcher.BeginInvoke(
    DispatcherPriority.Background, new Action(() => MethodName(parameter)));

For the datatype Double to int, you can use the following:

Double double = 5.00;

int integer = double.intValue();

Copy and paste the local.properties file from a project you created on your new computer to the folder containing the project from your old computer also works too if you don't want to (or know how to) create a new local.properties file.

Try this!

nssm in python 3+

(I converted my .py file to .exe with pyinstaller)

nssm: as said before

• run nssm install {ServiceName}

• On NSSM´s console:

  path: path\to\your\program.exe

  Startup directory: path\to\your\ #same as the path but without your program.exe

  Arguments: empty

If you don't want to convert your project to .exe

• create a .bat file with python {{your python.py file name}}
• and set the path to the .bat file

If you want to use the same library folder for several projects, you can reference it in gradle to an external location like this:

settings.gradle:

include 'app', ':volley'
project(':volley').projectDir = new File('../libraries/volley')

in your app build.gradle

dependencies {
    ...
    compile project(':volley')
...}

Since you have a list of links, you should be marking them up as a list (and not as paragraphs).

Listamatic has a bunch of examples of how you can style lists of links, including a number that are vertical lists with each link being centred (which is what you appear to be after). It also has a tutorial which explains the principles.

That part of the styling essentially boils down to "Set text-align: center on an element that is displaying as a block which contains the link text" (that could be the anchor itself (if you make it display as a block) or the list item containing it.

I do not understand why it does not work for you, it works for me : http://jsfiddle.net/igorlaszlo/wcm1soma/1/

The HTML

<div id="pagina-page" data-role="page">
    <div id="applyCSS">
    <!--all the elements here must follow a concrete CSS rules-->
        <a class="ui-bar-a">This "a" element text should be red
            <span class="ui-link-inherit">This span text in "a" element should be red too</span>
        </a>      
    </div>
</div>

The CSS

#applyCSS * {color:red;display:block;margin:20px;}

Maybe you have some special rules that you did not share with us...

If you already know for sure that the user is logged in (in your example if /index.html is protected):

UserDetails userDetails =
 (UserDetails)SecurityContextHolder.getContext().getAuthentication().getPrincipal();

To first check if the user is logged in, check that the current Authentication is not a AnonymousAuthenticationToken.

Authentication auth = SecurityContextHolder.getContext().getAuthentication();
if (!(auth instanceof AnonymousAuthenticationToken)) {
        // userDetails = auth.getPrincipal()
}

If your hardware supports it try using Java RdRand Utility of which I'm the author.

Its based on Intel's RDRAND instruction and is about 10 times faster than SecureRandom and no bandwidth issues for large volume implementation.

Note that this implementation only works on those CPU's that provide the instruction (i.e. when the rdrand processor flag is set). You need to explicitly instantiate it through the RdRandRandom() constructor; no specific Provider has been implemented.

If you search into one directory, you can do it:

select-string -Path "c:\temp\*.*" -Pattern "result"  -List | select Path

/(["\']).*?(?<!\\)(\\\\)*\1/is

should work with any quoted string

foreach (Control field in container.Controls)
            {
                if (field is TextBox)
                    ((TextBox)field).Clear();
                else if (field is ComboBox)
                    ((ComboBox)field).SelectedIndex=0;
                else
                    dgView.DataSource = null;
                    ClearAllText(field);
            }

The traceback module provides methods for formatting and printing exceptions and their tracebacks, e.g. this would print exception like the default handler does:

import traceback

try:
    1/0
except Exception:
    traceback.print_exc()

Output:

Traceback (most recent call last):
  File "C:\scripts\divide_by_zero.py", line 4, in <module>
    1/0
ZeroDivisionError: division by zero

The command (given by Tomek) can't delete a file, if it is read only. therefore, one can use -

import os, sys
import stat

def del_evenReadonly(action, name, exc):
    os.chmod(name, stat.S_IWRITE)
    os.remove(name)

if  os.path.exists("test/qt_env"):
    shutil.rmtree('test/qt_env',onerror=del_evenReadonly)

Try removing the contents of the <compilers> tag in the web.config file. Depending on who you're hosting with, some don't allow the compiler in production.

Your application is trying to compile when it is called and their servers won't allow it.

Apart from the other answers, that considered the connection string itself, it might simply be necessary to download the correct odbc driver. My client just faced this issue when executing a python app, that required it. you can check this by pressing windows + typing "odbc". the correct driver should appear in the drivers tab.

You made your button transparent. The first byte is the alpha.

If you don't have an index assigned to the data and you are not sure what the spacing is, you can use to let pandas assign an index and look for multiple spaces.

As it has been stated in react document:

You might be thinking that we’d need a separate effect to perform the cleanup. But code for adding and removing a subscription is so tightly related that useEffect is designed to keep it together. If your effect returns a function, React will run it when it is time to clean up:

useEffect(() => {
    function handleStatusChange(status) {
      setIsOnline(status.isOnline);
    }
    ChatAPI.subscribeToFriendStatus(props.friend.id, handleStatusChange);
    // Specify how to clean up after this effect:
    return function cleanup() {
      ChatAPI.unsubscribeFromFriendStatus(props.friend.id, handleStatusChange);
    };
  });

  if (isOnline === null) {
    return 'Loading...';
  }
  return isOnline ? 'Online' : 'Offline';
}

so the only thing that we need to have the componentWillUnmount in hooks is to return a function inside a useEffect, as explained above.

What is the need of static method in interface, static methods are used basically when you don't have to create an instance of object whole idea of interface is to bring in OOP concepts with introduction of static method you're diverting from concept.

TL;DR:

No, don't subscribe manually to them, don't use them in services. Use them as is shown in the documentation only to emit events in components. Don't defeat angular's abstraction.

Answer:

No, you should not subscribe manually to it.

EventEmitter is an angular2 abstraction and its only purpose is to emit events in components. Quoting a comment from Rob Wormald

[...] EventEmitter is really an Angular abstraction, and should be used pretty much only for emitting custom Events in components. Otherwise, just use Rx as if it was any other library.

This is stated really clear in EventEmitter's documentation.

Use by directives and components to emit custom Events.

What's wrong about using it?

Angular2 will never guarantee us that EventEmitter will continue being an Observable. So that means refactoring our code if it changes. The only API we must access is its emit() method. We should never subscribe manually to an EventEmitter.

All the stated above is more clear in this Ward Bell's comment (recommended to read the article, and the answer to that comment). Quoting for reference

Do NOT count on EventEmitter continuing to be an Observable!

Do NOT count on those Observable operators being there in the future!

These will be deprecated soon and probably removed before release.

Use EventEmitter only for event binding between a child and parent component. Do not subscribe to it. Do not call any of those methods. Only call eve.emit()

His comment is in line with Rob's comment long time ago.

So, how to use it properly?

Simply use it to emit events from your component. Take a look a the following example.

@Component({
    selector : 'child',
    template : `
        <button (click)="sendNotification()">Notify my parent!</button>
    `
})
class Child {
    @Output() notifyParent: EventEmitter<any> = new EventEmitter();
    sendNotification() {
        this.notifyParent.emit('Some value to send to the parent');
    }
}

@Component({
    selector : 'parent',
    template : `
        <child (notifyParent)="getNotification($event)"></child>
    `
})
class Parent {
    getNotification(evt) {
        // Do something with the notification (evt) sent by the child!
    }
}

How not to use it?

class MyService {
    @Output() myServiceEvent : EventEmitter<any> = new EventEmitter();
}

Stop right there... you're already wrong...

Hopefully these two simple examples will clarify EventEmitter's proper usage.

import React from 'react';
import Select from 'react-select';

const options = [
  { value: 'chocolate', label: 'Chocolate' },
  { value: 'strawberry', label: 'Strawberry' },
  { value: 'vanilla', label: 'Vanilla' },
];

class App extends React.Component {
  state = {
    selectedOption: null,
  };
  handleChange = selectedOption => {
    this.setState({ selectedOption });
    console.log(`Option selected:`, selectedOption);
  };
  render() {
    const { selectedOption } = this.state;

    return (
      <Select
        value={selectedOption}
        onChange={this.handleChange}
        options={options}
      />
    );
  }
}

In addition to what was already said - in order to avoid this error from interfering (stopping) other Javascript code on your page, you could try forcing the YouTube iframe to load last - after all other Javascript code is loaded.

A tuple consists of a number of values separated by commas. like

>>> t = 12345, 54321, 'hello!'
>>> t[0]
12345

tuple are index based (and also immutable) in Python.

Here in this case x = rows[1][1] + " " + rows[1][2] have only two index 0, 1 available but you are trying to access the 3rd index.

I don't think that other example is what you're looking for. If you're just updating one column from another column in the same table you should be able to use something like this.

update some_table set null_column = not_null_column where null_column is null

At the time of writing this answer, there was no method to embed which let the user navigate inside folders and view the files without her leaving the website (the method in other answers, makes everything open in a new tab on google drive website), so I made my own tool for it. To embed a drive, paste the iframe code below in your HTML:

<iframe src="https://googledriveembedder.collegefam.com/?key=YOUR_API_KEY&folderid=FOLDER_ID_WHIHCH_IS_PUBLICLY_VIEWABLE" style="border:none;" width="100%"></iframe>

In the above code, you need to have your own API key and the folder ID. You can set the height as per your wish.

To get the API key:

1.) Go to https://console.developers.google.com/ Create a new project.

2.) From the menu button, go to 'APIs and Services' --> 'Dashboard' --> Click on 'Enable APIs and Services'.

3.) Search for 'Google Drive API', enable it. Then go to "credentials' tab, and create credentials. Keep your API key unrestricted.

4.) Copy the newly generated API key.

To get the folder ID:

1.)Go to the google drive folder you want to embed (for example, drive.google.com/drive/u/0/folders/1v7cGug_e3lNT0YjhvtYrwKV7dGY-Nyh5u [this is not a real folder]) Ensure that the folder is publicly shared and visible to anyone.

2.) Copy the part after 'folders/', this is your folder ID.

Now put both the API key and folder id in the above code and embed.

Note: To hide the download button for files, add '&allowdl=no' at the end of the iframe's src URL.

I made the widget keeping mobile users in mind, however it suits both mobile and desktop. If you run into issues, leave a comment here. I have attached some screenshots of the content of the iframe here.

I use this, if you want only one view to be bring to front when needed:

containerView.bringChildToFront(topView);

containerView is container of views to be sorted, topView is view which i want to have as top most in container.

for multiple views to arrange is about to use setChildrenDrawingOrderEnabled(true) and overriding getChildDrawingOrder(int childCount, int i) as mentioned above.

Building on dnolans example, this is the version I could actually get to work (there were some errors with the boundary, encoding wasn't set) :-)

To send the data:

HttpWebRequest oRequest = null;
oRequest = (HttpWebRequest)HttpWebRequest.Create("http://you.url.here");
oRequest.ContentType = "multipart/form-data; boundary=" + PostData.boundary;
oRequest.Method = "POST";
PostData pData = new PostData();
Encoding encoding = Encoding.UTF8;
Stream oStream = null;

/* ... set the parameters, read files, etc. IE:
   pData.Params.Add(new PostDataParam("email", "[email protected]", PostDataParamType.Field));
   pData.Params.Add(new PostDataParam("fileupload", "filename.txt", "filecontents" PostDataParamType.File));
*/

byte[] buffer = encoding.GetBytes(pData.GetPostData());

oRequest.ContentLength = buffer.Length;

oStream = oRequest.GetRequestStream();
oStream.Write(buffer, 0, buffer.Length);
oStream.Close();

HttpWebResponse oResponse = (HttpWebResponse)oRequest.GetResponse();

The PostData class should look like:

public class PostData
{
    // Change this if you need to, not necessary
    public static string boundary = "AaB03x";

    private List<PostDataParam> m_Params;

    public List<PostDataParam> Params
    {
        get { return m_Params; }
        set { m_Params = value; }
    }

    public PostData()
    {
        m_Params = new List<PostDataParam>();
    }

    /// <summary>
    /// Returns the parameters array formatted for multi-part/form data
    /// </summary>
    /// <returns></returns>
    public string GetPostData()
    {
        StringBuilder sb = new StringBuilder();
        foreach (PostDataParam p in m_Params)
        {
            sb.AppendLine("--" + boundary);

            if (p.Type == PostDataParamType.File)
            {
                sb.AppendLine(string.Format("Content-Disposition: file; name=\"{0}\"; filename=\"{1}\"", p.Name, p.FileName));
                sb.AppendLine("Content-Type: application/octet-stream");
                sb.AppendLine();
                sb.AppendLine(p.Value);
            }
            else
            {
                sb.AppendLine(string.Format("Content-Disposition: form-data; name=\"{0}\"", p.Name));
                sb.AppendLine();
                sb.AppendLine(p.Value);
            }
        }

        sb.AppendLine("--" + boundary + "--");

        return sb.ToString();
    }
}

public enum PostDataParamType
{
    Field,
    File
}

public class PostDataParam
{
    public PostDataParam(string name, string value, PostDataParamType type)
    {
        Name = name;
        Value = value;
        Type = type;
    }

    public PostDataParam(string name, string filename, string value, PostDataParamType type)
    {
        Name = name;
        Value = value;
        FileName = filename;
        Type = type;

    public string Name;
    public string FileName;

If you type:

git config --global alias.a '!git add -A && git commit -m'

once, you will just need to type

git a

every time:

git a 'your comment'

For me this work for example here what happen is the main menu will be disabled when you open the registration form.

 frmUserRegistration frmMainMenu = new frmUserRegistration();
    frmMainMenu.ShowDialog(this);

use this

Dns.GetHostEntry(Dns.GetHostName())

You can make a class for each label and inside it put:

display: inline-block;

And width the value that you need.

The operators || and && are called conditional operators, while | and & are called bitwise operators. They serve different purposes.

Conditional operators works only with expressions that statically evaluate to boolean on both left- and right-hand sides.

Bitwise operators works with any numeric operands.

If you want to perform a logical comparison, you should use conditional operators, since you will add some kind of type safety to your code.

This is working for me (Excel 2016) with a new ActiveX button, assign a control to you button and you're all set.

Sub deactivate_buttons()

     ActiveSheet.Shapes.Item("CommandButton1").ControlFormat.Enabled = False

End Sub

It changes the "Enabled" property in the ActiveX button Properties box to False and the button becomes inactive and greyed out.

From the Metaprogramming Ruby book,

The require() method is quite similar to load(), but it’s meant for a different purpose. You use load() to execute code, and you use require() to import libraries.

app.config

app.name=Properties Sample Code
app.version=1.09  

Source code:

Properties prop = new Properties();
String fileName = "app.config";
InputStream is = null;
try {
    is = new FileInputStream(fileName);
} catch (FileNotFoundException ex) {
    ...
}
try {
    prop.load(is);
} catch (IOException ex) {
    ...
}
System.out.println(prop.getProperty("app.name"));
System.out.println(prop.getProperty("app.version"));

Output:

Properties Sample Code
1.09  

Quicksort has a better average case complexity but in some applications it is the wrong choice. Quicksort is vulnerable to denial of service attacks. If an attacker can choose the input to be sorted, he can easily construct a set that takes the worst case time complexity of o(n^2).

Mergesort's average case complexity and worst case complexity are the same, and as such doesn't suffer the same problem. This property of merge-sort also makes it the superior choice for real-time systems - precisely because there aren't pathological cases that cause it to run much, much slower.

I'm a bigger fan of Mergesort than I am of Quicksort, for these reasons.

If you want to do a transformation on the text on a character level, and get the transformed text back at the end, you would do something like this:

var value = "alma";
var new_value = value.split("").map(function(x) { return x+"E" }).join("")

So the steps:

• Split the string into an array (list) of characters
• Map each character via a functor
• Join the resulting array of chars together into the resulting string

Besides causes described already, I received this error because I'd include:

#include <fileapi.h>

Apparently it was not needed (despite of CreateDirectoryW call). After commenting out, compiler was happy. Very strange.

You should try this. It starts the program with no window. It actually flashes up for a second but goes away fairly quickly.

You can simply convert your radian result to degree by using

math.degrees and rounding appropriately to the required decimal places

When you do a push, git only takes the changes that you have committed.

Remember when you do a git status it shows you the files you changed since the last push?

Once you commit those changes and do a push they are the only files that get pushed so you don't have to worry about thinking that the entire master gets pushed because in reality it does not.

How to push a single file:

git commit yourfile.js
git status
git push origin master

The all above not work for me, I have just checked this and its work :

vertical-align: super;

 <div id="lbk_mng_rdooption" style="float: left;">
     <span class="bold" style="vertical-align: super;">View:</span>
 </div>

I know by padding or margin will work, but that is last choise I prefer.

This is the only comprehensive and reliable way I've found to do this.

Assume you want to merge "tag_1.0" into "mybranch".

    $git checkout tag_1.0 (will create a headless branch)
    $git branch -D tagbranch (make sure this branch doesn't already exist locally)
    $git checkout -b tagbranch
    $git merge -s ours mybranch
    $git commit -am "updated mybranch with tag_1.0"
    $git checkout mybranch
    $git merge tagbranch

The syntax for REPLACE:

REPLACE (string_expression,string_pattern,string_replacement)

So that the SQL you need should be:

UPDATE [DataTable] SET [ColumnValue] = REPLACE([ColumnValue], 'domain2', 'domain1')

val.Replace("-", "");
