More clean solution with enum for vertical scrolling.

enum ScrollDirection {
    case up, down
}

var scrollDirection: ScrollDirection? {
    if scrollView.panGestureRecognizer.translation(in: scrollView.superview).y > 0 {
        return .up
    } else if scrollView.panGestureRecognizer.translation(in: scrollView.superview).y < 0 {
        return .down
    } else {
        return nil
    }
}

Usage

switch scrollDirection {
case .up:   print("up")
case .down: print("down")
default:    print("no scroll")
}

Through personal expeirence I've found that it's not possible to round corners of an HTML table cell with pure CSS. Rounding a table's outermost border is possible.

You will have to resort to using images as described in this tutorial, or any similar :)

In order to avoid any dependency you can use java.util.Calendar as follow:

    Calendar now = Calendar.getInstance();
    now.add(Calendar.MINUTE, 10);
    Date teenMinutesFromNow = now.getTime();

In Java 8 we have new API:

    LocalDateTime dateTime = LocalDateTime.now().plus(Duration.of(10, ChronoUnit.MINUTES));
    Date tmfn = Date.from(dateTime.atZone(ZoneId.systemDefault()).toInstant());

Just adding this. In your package.json, if your "main": "index.js" is correctly set. Just use node .

{
  "name": "app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
     ...
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
     ...
  },
  "devDependencies": {
    ...
  }
}

If you are plotting time series graph and if you have used mtplotlib for drawing graphs then use median method to smooth-en the graph

smotDeriv = timeseries.rolling(window=20, min_periods=5, center=True).median()

where timeseries is your set of data passed you can alter windowsize for more smoothining.

No need for external plugins. In the Export JAR dialog, make sure you select all the necessary resources you want to export. By default, there should be no problem exporting other resource files as well (pictures, configuration files, etc...), see screenshot below.

Make sure you use the root folder of the JDK. Don't add "\lib" to the end of the path, where tools.jar is physically located. It took me an hour to figure that one out. Also, this post will help show you where Ant is looking for tools.jar:

Why does ANT tell me that JAVA_HOME is wrong when it is not?

The JPA specification says the following about persist().

If X is a detached object, the EntityExistsException may be thrown when the persist operation is invoked, or the EntityExistsException or another PersistenceException may be thrown at flush or commit time.

So using persist() would be suitable when the object ought not to be a detached object. You might prefer to have the code throw the PersistenceException so it fails fast.

Although the specification is unclear, persist() might set the @GeneratedValue @Id for an object. merge() however must have an object with the @Id already generated.

This solution is similar to walid2mi (thank you for inspiration), but allows the standard console input by the Read-Host cmdlet.

pros:

• can be run like standard .cmd file
• only one file for batch and powershell script
• powershell script may be multi-line (easy to read script)
• allows the standard console input (use the Read-Host cmdlet by standard way)

cons:

• requires powershell version 2.0+

Commented and runable example of batch-ps-script.cmd:

<# : Begin batch (batch script is in commentary of powershell v2.0+)
@echo off
: Use local variables
setlocal
: Change current directory to script location - useful for including .ps1 files
cd %~dp0
: Invoke this file as powershell expression
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
: Restore environment variables present before setlocal and restore current directory
endlocal
: End batch - go to end of file
goto:eof
#>
# here start your powershell script

# example: include another .ps1 scripts (commented, for quick copy-paste and test run)
#. ".\anotherScript.ps1"

# example: standard input from console
$variableInput = Read-Host "Continue? [Y/N]"
if ($variableInput -ne "Y") {
    Write-Host "Exit script..."
    break
}

# example: call standard powershell command
Get-Item .

Snippet for .cmd file:

<# : batch script
@echo off
setlocal
cd %~dp0
powershell -executionpolicy remotesigned -Command "Invoke-Expression $([System.IO.File]::ReadAllText('%~f0'))"
endlocal
goto:eof
#>
# here write your powershell commands...

The #! line tells the kernel (specifically, the implementation of the execve system call) that this program is written in an interpreted language; the absolute pathname that follows identifies the interpreter. Programs compiled to machine code begin with a different byte sequence -- on most modern Unixes, 7f 45 4c 46 (^?ELF) that identifies them as such.

You can put an absolute path to any program you want after the #!, as long as that program is not itself a #! script. The kernel rewrites an invocation of

./script arg1 arg2 arg3 ...

where ./script starts with, say, #! /usr/bin/perl, as if the command line had actually been

/usr/bin/perl ./script arg1 arg2 arg3

Or, as you have seen, you can use #! /bin/sh to write a script intended to be interpreted by sh.

The #! line is only processed if you directly invoke the script (./script on the command line); the file must also be executable (chmod +x script). If you do sh ./script the #! line is not necessary (and will be ignored if present), and the file does not have to be executable. The point of the feature is to allow you to directly invoke interpreted-language programs without having to know what language they are written in. (Do grep '^#!' /usr/bin/* -- you will discover that a great many stock programs are in fact using this feature.)

Here are some rules for using this feature:

• The #! must be the very first two bytes in the file. In particular, the file must be in an ASCII-compatible encoding (e.g. UTF-8 will work, but UTF-16 won't) and must not start with a "byte order mark", or the kernel will not recognize it as a #! script.
• The path after #! must be an absolute path (starts with /). It cannot contain space, tab, or newline characters.
• It is good style, but not required, to put a space between the #! and the /. Do not put more than one space there.
• You cannot put shell variables on the #! line, they will not be expanded.
• You can put one command-line argument after the absolute path, separated from it by a single space. Like the absolute path, this argument cannot contain space, tab, or newline characters. Sometimes this is necessary to get things to work (#! /usr/bin/awk -f), sometimes it's just useful (#! /usr/bin/perl -Tw). Unfortunately, you cannot put two or more arguments after the absolute path.
• Some people will tell you to use #! /usr/bin/env interpreter instead of #! /absolute/path/to/interpreter. This is almost always a mistake. It makes your program's behavior depend on the $PATH variable of the user who invokes the script. And not all systems have env in the first place.
• Programs that need setuid or setgid privileges can't use #!; they have to be compiled to machine code. (If you don't know what setuid is, don't worry about this.)

Regarding csh, it relates to sh roughly as Nutrimat Advanced Tea Substitute does to tea. It has (or rather had; modern implementations of sh have caught up) a number of advantages over sh for interactive usage, but using it (or its descendant tcsh) for scripting is almost always a mistake. If you're new to shell scripting in general, I strongly recommend you ignore it and focus on sh. If you are using a csh relative as your login shell, switch to bash or zsh, so that the interactive command language will be the same as the scripting language you're learning.

I prefer to do it in a more direct fashion. It does not have the Rows but is still has the array of rows.

tblCrm.DefaultView.RowFilter = "customertype = 'new'";

qtytotal = 0;
for (int i = 0; i < tblCrm.DefaultView.Count; i++)
{
    result = double.TryParse(tblCrm.DefaultView[i]["qty"].ToString(), out num);
    if (result == false) num = 0;
    qtytotal = qtytotal + num;
}

labQty.Text = qtytotal.ToString();

Also note the calendar.timegm() function as described by this blog entry:

import calendar
calendar.timegm(utc_timetuple)

The output should agree with the solution of vaab.

Coinbase has a REST API that gives you access to historical prices from their website. The data seems to show the Coinbase spot price (in USD) about every ten minutes.

Results are returned in CSV format. You must query the page number you want through the API. There are 1000 results (or price points) per page. That's about 7 days' worth of data per page.

EboMike's answer and Toby's answer are both on the right track, but they both contain a fatal flaw. The flaw is called lost notification.

The problem is, if a thread calls foo.notify(), it will not do anything at all unless some other thread is already sleeping in a foo.wait() call. The object, foo, does not remember that it was notified.

There's a reason why you aren't allowed to call foo.wait() or foo.notify() unless the thread is synchronized on foo. It's because the only way to avoid lost notification is to protect the condition with a mutex. When it's done right, it looks like this:

Consumer thread:

try {
    synchronized(foo) {
        while(! conditionIsTrue()) {
            foo.wait();
        }
        doSomethingThatRequiresConditionToBeTrue();
    }
} catch (InterruptedException e) {
    handleInterruption();
}

Producer thread:

synchronized(foo) {
    doSomethingThatMakesConditionTrue();
    foo.notify();
}

The code that changes the condition and the code that checks the condition is all synchronized on the same object, and the consumer thread explicitly tests the condition before it waits. There is no way for the consumer to miss the notification and end up stuck forever in a wait() call when the condition is already true.

Also note that the wait() is in a loop. That's because, in the general case, by the time the consumer re-acquires the foo lock and wakes up, some other thread might have made the condition false again. Even if that's not possible in your program, what is possible, in some operating systems, is for foo.wait() to return even when foo.notify() has not been called. That's called a spurious wakeup, and it is allowed to happen because it makes wait/notify easier to implement on certain operating systems.

I prefer runpy:

#!/usr/bin/env python
# coding: utf-8

import runpy

runpy.run_path(path_name='script-01.py')
runpy.run_path(path_name='script-02.py')
runpy.run_path(path_name='script-03.py')

Not really to answer OP's question (it's resolved anyway), but to help people who may stumble into the similar issue.

Here is what we had:

#
# A fatal error has been detected by the Java Runtime Environment:

The reason was defective RAM.

I encountered this problem in Laravel 5.8, what I did was to do composer require for each library and all where installed correctly.

Like so:

instead of adding it to the composer.json file or specifying a version:

composer require msurguy/honeypot: dev-master

I instead did without specifying any version:

composer require msurguy/honeypot

I hope it helps, thanks

Typically sites that do this by loading content via ajax and listening to the readystatechanged event to update the DOM with a loading GIF or the content.

How are you currently loading your content?

The code would be similar to this:

function load(url) {
    // display loading image here...
    document.getElementById('loadingImg').visible = true;
    // request your data...
    var req = new XMLHttpRequest();
    req.open("POST", url, true);

    req.onreadystatechange = function () {
        if (req.readyState == 4 && req.status == 200) {
            // content is loaded...hide the gif and display the content...
            if (req.responseText) {
                document.getElementById('content').innerHTML = req.responseText;
                document.getElementById('loadingImg').visible = false;
            }
        }
    };
    request.send(vars);
}

There are plenty of 3rd party javascript libraries that may make your life easier, but the above is really all you need.

You are using the beta version of angular CLI you can do this way.

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

Then type,

npm cache clean

Then go to the AppData folder which is hidden in your users and go to roaming folder which is inside AppData then go to npm folder and delete angular files in there and also go to npm-cache folder and delete angular components in there.After that restart your PC and type

npm install -g @angular/cli@latest

This worked for me ??

An example of how you could do this:

Some notes:

• LoggingHandler intercepts the request before it handles it to HttpClientHandler which finally writes to the wire.

• PostAsJsonAsync extension internally creates an ObjectContent and when ReadAsStringAsync() is called in the LoggingHandler, it causes the formatter inside ObjectContent to serialize the object and that's the reason you are seeing the content in json.

Logging handler:

public class LoggingHandler : DelegatingHandler
{
    public LoggingHandler(HttpMessageHandler innerHandler)
        : base(innerHandler)
    {
    }

    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        Console.WriteLine("Request:");
        Console.WriteLine(request.ToString());
        if (request.Content != null)
        {
            Console.WriteLine(await request.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

        Console.WriteLine("Response:");
        Console.WriteLine(response.ToString());
        if (response.Content != null)
        {
            Console.WriteLine(await response.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        return response;
    }
}

Chain the above LoggingHandler with HttpClient:

HttpClient client = new HttpClient(new LoggingHandler(new HttpClientHandler()));
HttpResponseMessage response = client.PostAsJsonAsync(baseAddress + "/api/values", "Hello, World!").Result;

Output:

Request:
Method: POST, RequestUri: 'http://kirandesktop:9095/api/values', Version: 1.1, Content: System.Net.Http.ObjectContent`1[
[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], Headers:
{
  Content-Type: application/json; charset=utf-8
}
"Hello, World!"

Response:
StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  Date: Fri, 20 Sep 2013 20:21:26 GMT
  Server: Microsoft-HTTPAPI/2.0
  Content-Length: 15
  Content-Type: application/json; charset=utf-8
}
"Hello, World!"

file() is not supported in Python 3

Use open() instead; see Built-in Functions - open().

Look for any module that uses buffering, and selectively disable it.

I'm running PHP 5.3.5 on CentOS 4.8, and after doing this I found eaccelerator needed an upgrade.

you can add this to your build gradel

android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            storeFile file("my.keystore")
            storePassword "password"
            keyAlias "MyReleaseKey"
            keyPassword "password"
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}

if you then need a keyHash do like this via android stdio terminal on project root folder

keytool -exportcert -alias my.keystore -keystore app/my.keystore.jks | openssl sha1 -binary | openssl base64

If you're using the PageFactory pattern or already have a reference to your WebElement, then you probably want to set the attribute, using your existing reference to the WebElement. (Rather than doing a document.getElementById(...) in your javascript)

The following sample allows you to set the attribute, using your existing WebElement reference.

Code Snippet

import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.FindBy;

public class QuickTest {

    RemoteWebDriver driver;

    @FindBy(id = "foo")
    private WebElement username;

    public void exampleUsage(RemoteWebDriver driver) {
        setAttribute(username, "attr", "10");
        setAttribute(username, "value", "bar");
    }

    public void setAttribute(WebElement element, String attName, String attValue) {
        driver.executeScript("arguments[0].setAttribute(arguments[1], arguments[2]);", 
                element, attName, attValue);
    }
}

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

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

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

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

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

You can also take a look at this module for angular

https://github.com/floydsoft/angular-underscore

The simplest solution would be

"\x00" * size # for a buffer of binary zeros
[0] * size # for a list of integer zeros

In general you should use more pythonic code like list comprehension (in your example: [0 for unused in xrange(100)]) or using string.join for buffers.

Given

std::vector<Rule>& topPriorityRules;

The correct way to remove the first element of the referenced vector is

topPriorityRules.erase(topPriorityRules.begin());

which is exactly what you suggested.

Looks like i need to do iterator overloading.

There is no need to overload an iterator in order to erase first element of std::vector.

P.S. Vector (dynamic array) is probably a wrong choice of data structure if you intend to erase from the front.

There is a subtle difference in terms of conflict management. In case of conflicts, a pull request in Github will result in a merge commit on the destination branch. In Gitlab, when a conflict is found, the modifications made will be on a merge commit on the source branch.

See https://docs.gitlab.com/ee/user/project/merge_requests/resolve_conflicts.html

"GitLab resolves conflicts by creating a merge commit in the source branch that is not automatically merged into the target branch. This allows the merge commit to be reviewed and tested before the changes are merged, preventing unintended changes entering the target branch without review or breaking the build."

There are two ways

Using split

Then just parse that string

var domain;
//find & remove protocol (http, ftp, etc.) and get domain
if (url.indexOf('://') > -1) {
    domain = url.split('/')[2];
} if (url.indexOf('//') === 0) {
    domain = url.split('/')[2];
} else {
    domain = url.split('/')[0];
}

//find & remove port number
domain = domain.split(':')[0];

Using Regex

 var r = /:\/\/(.[^/]+)/;
 "http://stackoverflow.com/questions/5343288/get-url".match(r)[1] 
 => stackoverflow.com

Hope this helps

It is recommended to use the spinal-case (which is highlighted by RFC3986), this case is used by Google, PayPal, and other big companies.

i am using the following code please try it out

DateFormat fm= new SimpleDateFormatter();

specify the format of the date you want for example "DD-MM_YYYY" or 'YYYY-mm-dd' then use the java Date datatype as

fm.format("object of java.util.date");

then it will parse your date

Weird! You are saying that you want to generate a recursion of 1<<15 depth???!!!!

I'd suggest DON'T try it. The size of the stack will be 2^15 * sizeof(stack-frame). I don't know what stack-frame size is, but 2^15 is 32.768. Pretty much... Well, if it stops at 1024 (2^10) you'll have to make it 2^5 times bigger, it is, 32 times bigger than with your actual setting.

you can view mysql root password , well i have tried it on mysql 5.5 so do not know about other new version well work or not

nano ~/.my.cnf

I figured it out. Need to use echo in PHP instead of return.

<?php 
  $output = some_function();
  echo $output;
?> 

And the jQ:

success: function(data) {
  doSomething(data);
}

I combined a few answers given by others in this question to come up with another alternative solution.

Goal: To always bundle the files, to disable the JS and CSS minification in the event that <compilation debug="true" ... /> and to always apply a custom transformation to the CSS bundle.

My solution:

1) In web.config: <compilation debug="true" ... />

2) In the Global.asax Application_Start() method:

 protected void Application_Start() {
     ...
     BundleTable.EnableOptimizations = true; // Force bundling to occur

     // If the compilation node in web.config indicates debugging mode is enabled
     // then clear all transforms. I.e. disable Js and CSS minification.
     if (HttpContext.Current.IsDebuggingEnabled) {
         BundleTable.Bundles.ToList().ForEach(b => b.Transforms.Clear());
     }

      // Add a custom CSS bundle transformer. In my case the transformer replaces a
      // token in the CSS file with an AppConfig value representing the website URL
      // in the current environment. E.g. www.mydevwebsite in Dev and
      // www.myprodwebsite.com in Production.
      BundleTable.Bundles.ToList()
          .FindAll(x => x.GetType() == typeof(StyleBundle))
          .ForEach(b => b.Transforms.Add(new MyStyleBundleTransformer()));
     ...
}

Very common problem in android
It can be broken down into 3 Pieces
1 ) start Activity B (Happens in Activity A)
2 ) Set requested data (Happens in activity B)
3 ) Receive requested data (Happens in activity A)

1) startActivity B

Intent i = new Intent(A.this, B.class);
startActivity(i);

2) Set requested data

In this part, you decide whether you want to send data back or not when a particular event occurs.
Eg: In activity B there is an EditText and two buttons b1, b2.
Clicking on Button b1 sends data back to activity A
Clicking on Button b2 does not send any data.

Sending data

b1......clickListener
{
   Intent resultIntent = new Intent();
   resultIntent.putExtra("Your_key","Your_value");
   setResult(RES_CODE_A,resultIntent);
   finish();
}

Not sending data

b2......clickListener
    {
       setResult(RES_CODE_B,new Intent());
       finish();
    }

user clicks back button
By default, the result is set with Activity.RESULT_CANCEL response code

3) Retrieve result

For that override onActivityResult method

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

if (resultCode == RES_CODE_A) {

     // b1 was clicked 
   String x = data.getStringExtra("RES_CODE_A");

}
else if(resultCode == RES_CODE_B){

   // b2 was clicked

}

I like to share the code i'm using to transpose a splited text based on +bluefeet answer. In this aproach i'm implemented as a procedure in MS SQL 2005

        ) piv
        order by rowid'

    EXEC (@query)

    DROP TABLE #tempSplitedTable

I'm mixing this solution with the information about howto order rows without order by (SQLAuthority.com) and the split function on MSDN (social.msdn.microsoft.com)

When you execute the prodecure

DECLARE @RC int
DECLARE @InputToSplit varchar(MAX)
DECLARE @Delimeter varchar(1)

set @InputToSplit = 'hello|beautiful|world'
set @Delimeter = '|'

EXECUTE @RC = [TransposeSplit] 
   @InputToSplit
  ,@Delimeter
GO

you obtaint the next result

  name       rowid  1      2          3
  col_value  1      hello  beautiful  world

For Windows, first install the git base from here: https://git-scm.com/downloads

Next, set the environment variable:

1. Press Windows+R and type sysdm.cpl
2. Select advance -> Environment variable
3. Select path-> edit the path and paste the below line:

C:\Program Files\Git\git-bash.exe

To test it, open the command window: press Windows+R, type cmd and then type ssh.

http://www.jsonschema2pojo.org/ Hi you can use this website to convert json to pojo.
control+Alt+shift+k

After that you can manualy convert that model class to kotlin model class. with the help of above shortcut.

Alternatively, you could try using pydot for producing the png file from dot:

...
tree.export_graphviz(dtreg, out_file='tree.dot') #produces dot file

import pydot
dotfile = StringIO()
tree.export_graphviz(dtreg, out_file=dotfile)
pydot.graph_from_dot_data(dotfile.getvalue()).write_png("dtree2.png")
...

If I understand you, perhaps you don't need an array of zeroes; rather, you need a hash. The hash keys will be the values in the other array and the hash values will be the number of times the value exists in the other array:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my %tallies;
$tallies{$_} ++ for @other_array;

print "$_ => $tallies{$_}\n" for sort {$a <=> $b} keys %tallies;    

Output:

0 => 3
1 => 1
2 => 2
3 => 3
4 => 1

To answer your specific question more directly, to create an array populated with a bunch of zeroes, you can use the technique in these two examples:

my @zeroes = (0) x 5;            # (0,0,0,0,0)

my @zeroes = (0) x @other_array; # A zero for each item in @other_array.
                                 # This works because in scalar context
                                 # an array evaluates to its size.

May I suggest a pure CSS solution altogether?

Just have a Div that you want to show the image in. Set the image as background. Then have the property background-size: cover or background-size: contain depending on how you want it.

cover will crop the image until smaller sides cover the box. contain will keep the entire image inside the div, leaving you with spaces on sides.

Check the snippet below.

div {_x000D_
  height: 300px;_x000D_
  width: 300px;_x000D_
  border: 3px dashed grey;_x000D_
  background-position: center;_x000D_
  background-repeat: no-repeat;_x000D_
}_x000D_
_x000D_
.cover-image {_x000D_
  background-size: cover;_x000D_
}_x000D_
_x000D_
.contain-image {_x000D_
  background-size: contain;_x000D_
}

<div class="cover-image" style="background-image:url(https://assets1.ignimgs.com/2019/04/25/avengers-endgame-1280y-1556226255823_1280w.jpg)">_x000D_
</div>_x000D_
<br/>_x000D_
<div class="contain-image" style="background-image:url(https://assets1.ignimgs.com/2019/04/25/avengers-endgame-1280y-1556226255823_1280w.jpg)">_x000D_
</div>

I know this is a pretty old topic, but I also had a same problem.

My solution:

how we fill the combobox:

foreach (KeyValuePair<int, string> item in listRegion)
{
    combo.Items.Add(item.Value);
    combo.ValueMember = item.Value.ToString();
    combo.DisplayMember = item.Key.ToString();
    combo.SelectedIndex = 0;
}

and that's how we get inside:

 MessageBox.Show(combo_region.DisplayMember.ToString());

I hope it help someone

As others said, Stopwatch should be the right tool for this. There can be few improvements made to it though, see this thread specifically: Benchmarking small code samples in C#, can this implementation be improved?.

I have seen some useful tips by Thomas Maierhofer here

Basically his code looks like:

//prevent the JIT Compiler from optimizing Fkt calls away
long seed = Environment.TickCount;

//use the second Core/Processor for the test
Process.GetCurrentProcess().ProcessorAffinity = new IntPtr(2);

//prevent "Normal" Processes from interrupting Threads
Process.GetCurrentProcess().PriorityClass = ProcessPriorityClass.High;

//prevent "Normal" Threads from interrupting this thread
Thread.CurrentThread.Priority = ThreadPriority.Highest;

//warm up
method();

var stopwatch = new Stopwatch()
for (int i = 0; i < repetitions; i++)
{
    stopwatch.Reset();
    stopwatch.Start();
    for (int j = 0; j < iterations; j++)
        method();
    stopwatch.Stop();
    print stopwatch.Elapsed.TotalMilliseconds;
}

Another approach is to rely on Process.TotalProcessTime to measure how long the CPU has been kept busy running the very code/process, as shown here This can reflect more real scenario since no other process affects the measurement. It does something like:

 var start = Process.GetCurrentProcess().TotalProcessorTime;
 method();
 var stop = Process.GetCurrentProcess().TotalProcessorTime;
 print (end - begin).TotalMilliseconds;

A naked, detailed implementation of the samething can be found here.

I wrote a helper class to perform both in an easy to use manner:

public class Clock
{
    interface IStopwatch
    {
        bool IsRunning { get; }
        TimeSpan Elapsed { get; }

        void Start();
        void Stop();
        void Reset();
    }



    class TimeWatch : IStopwatch
    {
        Stopwatch stopwatch = new Stopwatch();

        public TimeSpan Elapsed
        {
            get { return stopwatch.Elapsed; }
        }

        public bool IsRunning
        {
            get { return stopwatch.IsRunning; }
        }



        public TimeWatch()
        {
            if (!Stopwatch.IsHighResolution)
                throw new NotSupportedException("Your hardware doesn't support high resolution counter");

            //prevent the JIT Compiler from optimizing Fkt calls away
            long seed = Environment.TickCount;

            //use the second Core/Processor for the test
            Process.GetCurrentProcess().ProcessorAffinity = new IntPtr(2);

            //prevent "Normal" Processes from interrupting Threads
            Process.GetCurrentProcess().PriorityClass = ProcessPriorityClass.High;

            //prevent "Normal" Threads from interrupting this thread
            Thread.CurrentThread.Priority = ThreadPriority.Highest;
        }



        public void Start()
        {
            stopwatch.Start();
        }

        public void Stop()
        {
            stopwatch.Stop();
        }

        public void Reset()
        {
            stopwatch.Reset();
        }
    }



    class CpuWatch : IStopwatch
    {
        TimeSpan startTime;
        TimeSpan endTime;
        bool isRunning;



        public TimeSpan Elapsed
        {
            get
            {
                if (IsRunning)
                    throw new NotImplementedException("Getting elapsed span while watch is running is not implemented");

                return endTime - startTime;
            }
        }

        public bool IsRunning
        {
            get { return isRunning; }
        }



        public void Start()
        {
            startTime = Process.GetCurrentProcess().TotalProcessorTime;
            isRunning = true;
        }

        public void Stop()
        {
            endTime = Process.GetCurrentProcess().TotalProcessorTime;
            isRunning = false;
        }

        public void Reset()
        {
            startTime = TimeSpan.Zero;
            endTime = TimeSpan.Zero;
        }
    }



    public static void BenchmarkTime(Action action, int iterations = 10000)
    {
        Benchmark<TimeWatch>(action, iterations);
    }

    static void Benchmark<T>(Action action, int iterations) where T : IStopwatch, new()
    {
        //clean Garbage
        GC.Collect();

        //wait for the finalizer queue to empty
        GC.WaitForPendingFinalizers();

        //clean Garbage
        GC.Collect();

        //warm up
        action();

        var stopwatch = new T();
        var timings = new double[5];
        for (int i = 0; i < timings.Length; i++)
        {
            stopwatch.Reset();
            stopwatch.Start();
            for (int j = 0; j < iterations; j++)
                action();
            stopwatch.Stop();
            timings[i] = stopwatch.Elapsed.TotalMilliseconds;
            print timings[i];
        }
        print "normalized mean: " + timings.NormalizedMean().ToString();
    }

    public static void BenchmarkCpu(Action action, int iterations = 10000)
    {
        Benchmark<CpuWatch>(action, iterations);
    }
}

Just call

Clock.BenchmarkTime(() =>
{
    //code

}, 10000000);

or

Clock.BenchmarkCpu(() =>
{
    //code

}, 10000000);

The last part of the Clock is the tricky part. If you want to display the final timing, its up to you to choose what sort of timing you want. I wrote an extension method NormalizedMean which gives you the mean of the read timings discarding the noise. I mean I calculate the the deviation of each timing from the actual mean, and then I discard the values which was farer (only the slower ones) from the mean of deviation (called absolute deviation; note that its not the often heard standard deviation), and finally return the mean of remaining values. This means, for instance, if timed values are { 1, 2, 3, 2, 100 } (in ms or whatever), it discards 100, and returns the mean of { 1, 2, 3, 2 } which is 2. Or if timings are { 240, 220, 200, 220, 220, 270 }, it discards 270, and returns the mean of { 240, 220, 200, 220, 220 } which is 220.

public static double NormalizedMean(this ICollection<double> values)
{
    if (values.Count == 0)
        return double.NaN;

    var deviations = values.Deviations().ToArray();
    var meanDeviation = deviations.Sum(t => Math.Abs(t.Item2)) / values.Count;
    return deviations.Where(t => t.Item2 > 0 || Math.Abs(t.Item2) <= meanDeviation).Average(t => t.Item1);
}

public static IEnumerable<Tuple<double, double>> Deviations(this ICollection<double> values)
{
    if (values.Count == 0)
        yield break;

    var avg = values.Average();
    foreach (var d in values)
        yield return Tuple.Create(d, avg - d);
}

The answers above are still using the old Python 3.4 style coroutines. Here is what you would write if you got Python 3.5+.

aiohttp supports http proxy now

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = [
            'http://python.org',
            'https://google.com',
            'http://yifei.me'
        ]
    tasks = []
    async with aiohttp.ClientSession() as session:
        for url in urls:
            tasks.append(fetch(session, url))
        htmls = await asyncio.gather(*tasks)
        for html in htmls:
            print(html[:100])

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

I was facing the same problem today and made up a wrapper class, which checks before every method if the element reference is still valid. My solution to retrive the element is pretty simple so i thought i'd just share it.

private void setElementLocator()
{
    this.locatorVariable = "selenium_" + DateTimeMethods.GetTime().ToString();
    ((IJavaScriptExecutor)this.driver).ExecuteScript(locatorVariable + " = arguments[0];", this.element);
}

private void RetrieveElement()
{
    this.element = (IWebElement)((IJavaScriptExecutor)this.driver).ExecuteScript("return " + locatorVariable);
}

You see i "locate" or rather save the element in a global js variable and retrieve the element if needed. If the page gets reloaded this reference will not work anymore. But as long as only changes are made to doom the reference stays. And that should do the job in most cases.

Also it avoids re-searching the element.

I do like this for list items in <menu> elements. Consider the following markup:

<menu>
  <li><a href="/member/profile">Profile</a></li>
  <li><a href="/member/options">Options</a></li>
  <li><a href="/member/logout">Logout</a></li>
</menu>

I style it with the following CSS:

menu > li {
  display: inline;
}

menu > li::after {
  content: ' | ';
}

menu > li:last-child::after {
  content: '';
}

This will display:

Profile | Options | Logout

And this is possible because of what Martin Atkins explained on his comment

Note that in CSS 2 you would use :after, not ::after. If you use CSS 3, use ::after (two semi-columns) because ::after is a pseudo-element (a single semi-column is for pseudo-classes).

This is a pretty old thread but the problem is still the same -

I tried multiple things, none of them worked -

1. Added a Start In Path (without quotes)
2. Removed the complete path of the batch file in the Program/Script field etc
3. Added C:\Windows\system32\cmd.exe to the Program and added /c myscript.bat to the arguments field.

This is what worked for me -

Program/Script Field - cmd

Add Arguments - /c myscript.bat

Start In : Path to myscript.bat

I know you had this problem in an internal host, but I had experienced such an issue before in an external host and in my case it had it's own resolution, maybe it could save somebody's time:

In fact my website was STOPPED by some reason which currently I'm not aware of, to check it out if you have the same problem, in WebsitePanel main page go to Web -> Websites then select the domain name of your website from the list, after that in the right side of the page just opened, check if you see the word STARTED, else if you see the word STOPPED, make it get started again. That's all.

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

If your server is called SERVERX for example, this is how I did it...

EXEC sp_serveroption 'SERVERX', 'DATA ACCESS', TRUE;
DECLARE @CMD VARCHAR(1000);
DECLARE @StudentID CHAR(10);
SET @StudentID = 'STUDENT01';
SET @CMD = 'SELECT * FROM OPENQUERY([SERVERX], ''SET FMTONLY OFF; SET NOCOUNT ON; EXECUTE MYDATABASE.dbo.MYSTOREDPROC ' + @StudentID + ''') WHERE SOMEFIELD = SOMEVALUE';
EXEC (@CMD);

To check this worked, I commented out the EXEC() command line and replaced it with SELECT @CMD to review the command before trying to execute it! That was to make sure all the correct number of single-quotes were in the right place. :-)

I hope that helps someone.

I found a solution that worked for me. I downgraded from the latest guzzle to version ~4.0 and it worked.

In composer.json add "guzzlehttp/guzzle": "~4.0"

Hope it helps someone

I would like to stress that, even if there are situations where if expr : isn't sufficient because one wants to make sure expr is True and not just different from 0/None/whatever, is is to be prefered from == for the same reason S.Lott mentionned for avoiding == None.

It is indeed slightly more efficient and, cherry on the cake, more human readable.

In [1]: %timeit (1 == 1) == True
38.1 ns ± 0.116 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [2]: %timeit (1 == 1) is True
33.7 ns ± 0.141 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

Always try to do an associative fetch, that way you can easy get what you want in multiple case result

Here's an example

$result = $mysqli->query("SELECT COUNT(*) AS cityCount FROM myCity")
$row = $result->fetch_assoc();
echo $row['cityCount']." rows in table myCity.";

The other answers assume that your compiler is C++11 compliant. That is fine if it is. But what if you are using an older compiler?

I picked up the following hack somewhere on the net. It works well enough for me:

  #if defined __UINT32_MAX__ or UINT32_MAX
  #include <inttypes.h>
  #else
  typedef unsigned char uint8_t;
  typedef unsigned short uint16_t;
  typedef unsigned long uint32_t;
  typedef unsigned long long uint64_t;
  #endif

It is not portable, of course. But it might work for your compiler.

I think you should go to:

File ->Project Structure->SDK Location->

there select your sdk location.

I just click 'Retry' and it's ok! Also run on Win7 64-bit.

I had the same issue after upgrading to macOS Catalina. This didn't work for me:

xcode-select --install

Downloading and installing Command Line Tools for Xcode 12 did it!

You could use HTML entities:

• ' for '
• " for "
• ...

For more, you can take a look at Character entity references in HTML.

The two queries may not be semantically equivalent. If a employee works for more than one department (possible in the enterprise I work for; admittedly, this would imply your table is not fully normalized) then the first query would return duplicate rows whereas the second query would not. To make the queries equivalent in this case, the DISTINCT keyword would have to be added to the SELECT clause, which may have an impact on performance.

Note there is a design rule of thumb that states a table should model an entity/class or a relationship between entities/classes but not both. Therefore, I suggest you create a third table, say OrgChart, to model the relationship between employees and departments.

VBA stands for Visual Basic for Applications and so is the small "for applications" scripting brother of VB. VBA is indeed available in Excel, but also in the other office applications.

With VB, one can create a stand-alone windows application, which is not possible with VBA.

It is possible for developers however to "embed" VBA in their own applications, as a scripting language to automate those applications.

Edit: From the VBA FAQ:

Q. What is Visual Basic for Applications?

A. Microsoft Visual Basic for Applications (VBA) is an embeddable programming environment designed to enable developers to build custom solutions using the full power of Microsoft Visual Basic. Developers using applications that host VBA can automate and extend the application functionality, shortening the development cycle of custom business solutions.

Note that VB.NET is even another language, which only shares syntax with VB.

double click the button and add write // this.close();

  private void buttonClick(object sender, EventArgs e)
{
    this.Close();
}

Array indexes in JavaScript start at zero for the first item, so try this:

var firstArrayItem = myValues[0]

Of course, if you actually want the second item in the array at index 1, then it's myValues[1].

See Accessing array elements for more info.

Another, simpler approach (to an old question)..
would be to place elements as siblings and use:

Adjacent Sibling Selector (+) or General Sibling Selector (~)

<div id="parent">
  <!-- control should come before the target... think "cascading" ! -->
  <button id="control">Hover Me!</button>
  <div id="target">I'm hovered too!</div>
</div>

#parent {
  position: relative;
  height: 100px;
}

/* Move button control to bottom. */
#control {
  position: absolute;
  bottom: 0;
}

#control:hover ~ #target {
  background: red;
}

Do you mean you want to execute code in function1 regardless of whether function2 threw an exception or not? Have you looked at the finally-block? http://msdn.microsoft.com/en-us/library/zwc8s4fz.aspx

If you use old version of MySQL you can always use \P combined with some nice piece of awk code. Interesting example here

http://www.dbasquare.com/2012/03/28/how-to-work-with-a-long-process-list-in-mysql/

Isn't it exactly what you need?

A bit of a hack, but this gives the effect of a multi-line select, puts in a gray bgcolor for your multi line, and if you select any of the gray text, it selects the first of the grouping. Kinda clever I'd say :) The first option also shows how you can put a title tag in for an option as well.

 function SelectFirst(SelVal) {_x000D_
   var arrSelVal = SelVal.split(",")_x000D_
   if (arrSelVal.length > 1) {_x000D_
     Valuetoselect = arrSelVal[0];_x000D_
     document.getElementById("select1").value = Valuetoselect;_x000D_
   }_x000D_
 }

<select name="select1" id="select1" onchange="SelectFirst(this.value)">_x000D_
  <option value="1" title="this is my long title for the yes option">Yes</option>_x000D_
  <option value="2">No</option>_x000D_
  <option value="2,1" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is my description for the no option</option>_x000D_
  <option value="2,2" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is line 2 for the no option</option>_x000D_
  <option value="3">Maybe</option>_x000D_
  <option value="3,1" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is my description for Maybe option</option>_x000D_
  <option value="3,2" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is line 2 for the Maybe option</option>_x000D_
  <option value="3,3" style="background:#eeeeee">&nbsp;&nbsp;&nbsp;This is line 3 for the Maybe option</option>_x000D_
</select>

check it: Android Studio->file->project structure->app->flavors->min sdk version and if you want to run your application on your mobile you have to set min sdk version less than your device sdk(API) you can install any API levels.

You can declare columns/variables as varchar2(n CHAR) and varchar2(n byte).

n CHAR means the variable will hold n characters. In multi byte character sets you don't always know how many bytes you want to store, but you do want to garantee the storage of a certain amount of characters.

n bytes means simply the number of bytes you want to store.

varchar is deprecated. Do not use it. What is the difference between varchar and varchar2?

Find below a simple example illustrating how to get class and method names.

public static void main(String args[])
   {
      callMe();
   }

   void callMe()
   {
      try
      {
         throw new Exception("Who called me?");
      }
      catch( Exception e )
      {
         System.out.println( "I was called by " + 
                             e.getStackTrace()[1].getClassName() + 
                             "." +
                             e.getStackTrace()[1].getMethodName() + 
                             "()!" );
      }
   }

e has getClassName(), getFileName(), getLineNumber() and getMethodName()...

There are few mistakes you are doing:

1. You need to add proper object in the array in addRow method
2. You can use splice method to remove an element from an array at particular index.
3. You need to pass the current row as prop to my-item component, where this can be modified.

You can see working code here.

addRow(){
   this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
   this. itemList.splice(index, 1)
}

A slight edit on an example provided in http://matplotlib.org/users/shell.html:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_title('click on points')

line, = ax.plot(np.random.rand(100), '-', picker=5)  # 5 points tolerance


def onpick(event):
    thisline = event.artist
    xdata = thisline.get_xdata()
    ydata = thisline.get_ydata()
    ind = event.ind
    print('onpick points:', *zip(xdata[ind], ydata[ind]))


fig.canvas.mpl_connect('pick_event', onpick)

plt.show()

This plots a straight line plot, as Sohaib was asking

Bash is the standard for Linux.
My experience is that it is easier to find help for bash than for ksh or csh.

I faced a case where I had to use std::unique_ptr<bool[]>, which was in the HDF5 library (A library for efficient binary data storage, used a lot in science). Some compilers (Visual Studio 2015 in my case) provide compression of std::vector<bool> (by using 8 bools in every byte), which is a catastrophe for something like HDF5, which doesn't care about that compression. With std::vector<bool>, HDF5 was eventually reading garbage because of that compression.

Guess who was there for the rescue, in a case where std::vector didn't work, and I needed to allocate a dynamic array cleanly? :-)

First : npm install mongoose-timestamp

Next: let Timestamps = require('mongoose-timestamp')

Next: let MySchema = new Schema

Next: MySchema.plugin(Timestamps)

Next : const Collection = mongoose.model('Collection',MySchema)

Then you can use the Collection.createdAt or Collection.updatedAt anywhere your want.

Created on: Date Of The Week Month Date Year 00:00:00 GMT

Time is in this format.

Yes, you can use the native javascript Date() object and its methods.

For instance you can create a function like:

function formatDate(date) {
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return (date.getMonth()+1) + "/" + date.getDate() + "/" + date.getFullYear() + "  " + strTime;
}

var d = new Date();
var e = formatDate(d);

alert(e);

And display also the am / pm and the correct time.

Remember to use getFullYear() method and not getYear() because it has been deprecated.

Just two more things I found helpful to know, even if they are not part of the question, really.

You can use the relayEvents method to tell a component to listen for certain events of another component and then fire them again as if they originate from the first component. The API docs give the example of a grid relaying the store load event. It is quite handy when writing custom components that encapsulate several sub-components.

The other way around, i.e. passing on events received by an encapsulating component mycmp to one of its sub-components subcmp, can be done like this

mycmp.on('show' function (mycmp, eOpts)
{
   mycmp.subcmp.fireEvent('show', mycmp.subcmp, eOpts);
});

If you are unable to install mysqlclient you can also install pymysql:

pip install pymysql

This works same as MySqldb. After that use pymysql all over instead of MySQLdb

host just includes the port number if there is one specified. If there is no port number specifically in the URL, then it returns the same as hostname. You pick whether you care to match the port number or not. See https://developer.mozilla.org/en/window.location for more info.

I would assume you want hostname to just get the site name.

If you're using gulp, then you can use this plugin:

Install this plugin with the command:

npm install gulp-remove-logging

Next, add this line to your gulpfile:

var gulp_remove_logging = require("gulp-remove-logging");

Lastly, add the configuration settings (see below) to your gulpfile.

Task Configuration

gulp.task("remove_logging", function() {
     return gulp.src("src/javascripts/**/*.js")
    .pipe(
      gulp_remove_logging()
    )
    .pipe(
      gulp.dest(
        "build/javascripts/"
      )
    ); });

To further touch on Darin's answer, you can get to your specific claims by using the FindFirst method:

var identity = (ClaimsIdentity)User.Identity;
var role = identity.FindFirst(ClaimTypes.Role).Value;

select *
from
    tableA a
        inner join
    tableB b
        on a.common = b.common
        inner join 
    TableC c
        on b.common = c.common

Are you sure you requested the proper permission in your Manifest file?

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

You can use the AlarmManager1 class to fire off an intent that starts your activity and acquires the wake lock. This will turn on the screen and keep it on. Releasing the wakelock will allow the device to go to sleep on its own.

You can also take a look at using the PowerManager to set the device to sleep: http://developer.android.com/reference/android/os/PowerManager.html#goToSleep(long)

I have done this for Retina/Non-Retina display as

BOOL isRetina = FALSE;

if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
    if ([[UIScreen mainScreen] scale] == 2.0) {
        isRetina = TRUE;
    } else {
        isRetina = FALSE;
    }
}

if (isRetina) {
    self.edgesForExtendedLayout=UIRectEdgeNone;
    self.extendedLayoutIncludesOpaqueBars=NO;
    self.automaticallyAdjustsScrollViewInsets=NO;
}

We can use map function

print map(str, EmployeeList)

@Coincoin

The real power of the foreach extension method involves reusability of the Action<> without adding unnecessary methods to your code. Say that you have 10 lists and you want to perform the same logic on them, and a corresponding function doesn't fit into your class and is not reused. Instead of having ten for loops, or a generic function that is obviously a helper that doesn't belong, you can keep all of your logic in one place (the Action<>. So, dozens of lines get replaced with

Action<blah,blah> f = { foo };

List1.ForEach(p => f(p))
List2.ForEach(p => f(p))

etc...

The logic is in one place and you haven't polluted your class.

You can find all the HTML Special Characters in this page http://www.degraeve.com/reference/specialcharacters.php Just replace the code where you want to put that character. :-)

In addition to the ioctl() method Filip demonstrated you can use getifaddrs(). There is an example program at the bottom of the man page.

var_dump($value)

it solved my problem, hope yours too.

This might be useful for someone.

Numpy's histogram function returns the edges of each bin, rather than the value of the bin. This makes sense for floating-point numbers, which can lie within an interval, but may not be the desired result when dealing with discrete values or integers (0, 1, 2, etc). In particular, the length of bins returned from np.histogram is not equal to the length of the counts / density.

To get around this, I used np.digitize to quantize the input, and count the fraction of counts for each bin. You could easily edit to get the integer number of counts.

def compute_PMF(data):
    import numpy as np
    from collections import Counter
    _, bins = np.histogram(data, bins='auto', range=(data.min(), data.max()), density=False)
    h = Counter(np.digitize(data,bins) - 1)
    weights = np.asarray(list(h.values())) 
    weights = weights / weights.sum()
    values = np.asarray(list(h.keys()))
    return weights, values

None of these solutions worked for me. But I was able to get vertical centering by using <div class="form-row align-items-center"> for each form row, per the Bootstrap examples.

Consider a right angled triangle. We label the hypotenuse r, the horizontal side y and the vertical side x. The angle of interest α is the angle between x and r.

C++ atan2(y, x) will give us the value of angle α in radians. atan is used if we only know or are interested in y/x not y and x individually. So if p = y/x then to get α we'd use atan(p).

You cannot use atan2 to determine the quadrant, you can use atan2 only if you already know which quadrant your in! In particular positive x and y imply the first quadrant, positive y and negative x, the second and so on. atan or atan2 themselves simply return a positive or a negative number, nothing more.

I know this is older but the correct way to do this now is

string Domain = HttpContext.Current.Request.Url.Authority

That will get the DNS or ip address with port for a server.

The following implementation of a PriorityQueue uses SortedSet from the System library.

using System;
using System.Collections.Generic;

namespace CDiggins
{
    interface IPriorityQueue<T, K> where K : IComparable<K>
    {
        bool Empty { get; }
        void Enqueue(T x, K key);
        void Dequeue();
        T Top { get; }
    }

    class PriorityQueue<T, K> : IPriorityQueue<T, K> where K : IComparable<K>
    {
        SortedSet<Tuple<T, K>> set;

        class Comparer : IComparer<Tuple<T, K>> {
            public int Compare(Tuple<T, K> x, Tuple<T, K> y) {
                return x.Item2.CompareTo(y.Item2);
            }
        }

        PriorityQueue() { set = new SortedSet<Tuple<T, K>>(new Comparer()); }
        public bool Empty { get { return set.Count == 0;  } }
        public void Enqueue(T x, K key) { set.Add(Tuple.Create(x, key)); }
        public void Dequeue() { set.Remove(set.Max); }
        public T Top { get { return set.Max.Item1; } }
    }
}

exec is often used in conjunction with fork, which I saw that you also asked about, so I will discuss this with that in mind.

exec turns the current process into another program. If you ever watched Doctor Who, then this is like when he regenerates -- his old body is replaced with a new body.

The way that this happens with your program and exec is that a lot of the resources that the OS kernel checks to see if the file you are passing to exec as the program argument (first argument) is executable by the current user (user id of the process making the exec call) and if so it replaces the virtual memory mapping of the current process with a virtual memory the new process and copies the argv and envp data that were passed in the exec call into an area of this new virtual memory map. Several other things may also happen here, but the files that were open for the program that called exec will still be open for the new program and they will share the same process ID, but the program that called exec will cease (unless exec failed).

The reason that this is done this way is that by separating running a new program into two steps like this you can do some things between the two steps. The most common thing to do is to make sure that the new program has certain files opened as certain file descriptors. (remember here that file descriptors are not the same as FILE *, but are int values that the kernel knows about). Doing this you can:

int X = open("./output_file.txt", O_WRONLY);

pid_t fk = fork();
if (!fk) { /* in child */
    dup2(X, 1); /* fd 1 is standard output,
                   so this makes standard out refer to the same file as X  */
    close(X);

    /* I'm using execl here rather than exec because
       it's easier to type the arguments. */
    execl("/bin/echo", "/bin/echo", "hello world");
    _exit(127); /* should not get here */
} else if (fk == -1) {
    /* An error happened and you should do something about it. */
    perror("fork"); /* print an error message */
}
close(X); /* The parent doesn't need this anymore */

This accomplishes running:

/bin/echo "hello world" > ./output_file.txt

from the command shell.

Simple answer

If you are behind a proxy server, please set the proxy for curl. The curl is not able to connect to server so it shows wrong version number. Set proxy by opening subl ~/.curlrc or use any other text editor. Then add the following line to file: proxy= proxyserver:proxyport For e.g. proxy = 10.8.0.1:8080

If you are not behind a proxy, make sure that the curlrc file does not contain the proxy settings.

I think it is much more simple solution:

window.location = (""+window.location).replace(/#[A-Za-z0-9_]*$/,'')+"#myAnchor"

This method does not reload the website, and sets the focus on the anchors which are needed for screen reader.

I also need the container name or Id which a script requires to attach to the container. took some tweaking but this works perfectly well for me...

export svr=$(docker ps --format "table {{.ID}}"| sed 's/CONTAINER ID//g' | sed '/^[[:space:]]*$/d')
docker exec -it $svr bash

The sed command is needed to get rid of the fact that the words CONTAINER ID gets printed too ... but I just need the actual id stored in a var.

This is my solution to scroll to the top on a button click.

$(".btn").click(function () {
if ($(this).text() == "Show options") {
$(".tabs").animate(
  {
    scrollTop: $(window).scrollTop(0)
  },
  "slow"
 );
 }
});

Datanewolf's code is ALMOST right. I had to reverse both the winding and the normals to make it work properly with the fixed pipeline. The below works correctly with cull on or off for me:

std::vector<GLfloat> vertices;
std::vector<GLfloat> normals;
std::vector<GLfloat> texcoords;
std::vector<GLushort> indices;

float const R = 1./(float)(rings-1);
float const S = 1./(float)(sectors-1);
int r, s;

vertices.resize(rings * sectors * 3);
normals.resize(rings * sectors * 3);
texcoords.resize(rings * sectors * 2);
std::vector<GLfloat>::iterator v = vertices.begin();
std::vector<GLfloat>::iterator n = normals.begin();
std::vector<GLfloat>::iterator t = texcoords.begin();
for(r = 0; r < rings; r++) for(s = 0; s < sectors; s++) {
    float const y = sin( -M_PI_2 + M_PI * r * R );
    float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
    float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );

    *t++ = s*S;
    *t++ = r*R;

    *v++ = x * radius;
    *v++ = y * radius;
    *v++ = z * radius;

    *n++ = -x;
    *n++ = -y;
    *n++ = -z;
}

indices.resize(rings * sectors * 4);
std::vector<GLushort>::iterator i = indices.begin();
for(r = 0; r < rings-1; r++)
    for(s = 0; s < sectors-1; s++) {
       /* 
        *i++ = r * sectors + s;
        *i++ = r * sectors + (s+1);
        *i++ = (r+1) * sectors + (s+1);
        *i++ = (r+1) * sectors + s;
        */
         *i++ = (r+1) * sectors + s;
         *i++ = (r+1) * sectors + (s+1);
        *i++ = r * sectors + (s+1);
         *i++ = r * sectors + s;

}

Edit: There was a question on how to draw this... in my code I encapsulate these values in a G3DModel class. This is my code to setup the frame, draw the model, and end it:

void GraphicsProvider3DPriv::BeginFrame()const{
        int win_width;
        int win_height;// framework of choice here
        glfwGetWindowSize(window, &win_width, &win_height); // retrieve window
        float const win_aspect = (float)win_width / (float)win_height;
        // set lighting
        glEnable(GL_LIGHTING);
        glEnable(GL_LIGHT0);
        glEnable(GL_DEPTH_TEST);
        GLfloat lightpos[] = {0, 0.0, 0, 0.};
        glLightfv(GL_LIGHT0, GL_POSITION, lightpos);
        GLfloat lmodel_ambient[] = { 0.2, 0.2, 0.2, 1.0 };
        glLightModelfv(GL_LIGHT_MODEL_AMBIENT, lmodel_ambient);
        glLightModeli(GL_LIGHT_MODEL_TWO_SIDE, GL_TRUE);
        // set up world transform
        glClearColor(0.f, 0.f, 0.f, 1.f);
        glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT|GL_ACCUM_BUFFER_BIT);
        glMatrixMode(GL_PROJECTION);
        glLoadIdentity();

        gluPerspective(45, win_aspect, 1, 10);

        glMatrixMode(GL_MODELVIEW);

    }


    void GraphicsProvider3DPriv::DrawModel(const G3DModel* model, const Transform3D transform)const{
        G3DModelPriv* privModel = (G3DModelPriv *)model;
        glPushMatrix();
        glLoadMatrixf(transform.GetOGLData());

        glEnableClientState(GL_VERTEX_ARRAY);
        glEnableClientState(GL_NORMAL_ARRAY);
        glEnableClientState(GL_TEXTURE_COORD_ARRAY);

        glVertexPointer(3, GL_FLOAT, 0, &privModel->vertices[0]);
        glNormalPointer(GL_FLOAT, 0, &privModel->normals[0]);
        glTexCoordPointer(2, GL_FLOAT, 0, &privModel->texcoords[0]);

        glEnable(GL_TEXTURE_2D);
        //glFrontFace(GL_CCW);
        glEnable(GL_CULL_FACE);
        glActiveTexture(GL_TEXTURE0);
        glBindTexture(GL_TEXTURE_2D, privModel->texname);

        glDrawElements(GL_QUADS, privModel->indices.size(), GL_UNSIGNED_SHORT, &privModel->indices[0]);
        glPopMatrix();
        glDisable(GL_TEXTURE_2D);

    }

    void GraphicsProvider3DPriv::EndFrame()const{
        /* Swap front and back buffers */
        glDisable(GL_LIGHTING);
        glDisable(GL_LIGHT0);
        glDisable(GL_CULL_FACE);
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

This error message also occurs when you created the SCHEMA with a different COLLATION than the one which is used in the dump. So, if the dump contains

CREATE TABLE `mytab` (
..
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

you should also reflect this in the SCHEMA collation:

CREATE SCHEMA myschema COLLATE utf8_unicode_ci;

I had been using utf8mb4_general_ci in the schema, cause my script came from a fresh V8 installation, now loading a DB on old 5.7 crashed and drove me nearly crazy.

So, maybe this helps you saving some frustating hours... :-)

(MacOS 10.3, mysql 5.7)

$ ls -ld directory

ls is the list command.

- indicates the beginning of the command options.

l asks for a long list which includes the permissions.

d indicates that the list should concern the named directory itself; not its contents. If no directory name is given, the list output will pertain to the current directory.

What about .GlobalEnv$a <- "new" ? I saw this explicit way of creating a variable in a certain environment here: http://adv-r.had.co.nz/Environments.html. It seems shorter than using the assign() function.

Instead of above way u can achieve the solution simply by following method..

public static void main(String args[]) {
    String ini = "Hi there";
    for (int i = 0; i < ini.length(); i++) {
        System.out.print(" " + ini.charAt(i));
    }
}

Think of it this way...

POST - create

PUT - replace

PATCH - update

GET - read

DELETE - delete

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

Let's do a test with 2 examples:

    <?php    
    $memory = (int)ini_get("memory_limit"); // Display your current value in php.ini (for example: 64M)
    echo "original memory: ".$memory."<br>";
    ini_set('memory_limit','128M'); // Try to override the memory limit for this script
    echo "new memory:".$memory;
    }
    // Will display:
    // original memory: 64
    // new memory: 64
    ?>

The above example doesn't work for overriding the memory_limit value. But This will work:

    <?php
    $memory = (int)ini_get("memory_limit"); // get the current value
    ini_set('memory_limit','128'); // override the value
    echo "original memory: ".$memory."<br>"; // echo the original value
    $new_memory = (int)ini_get("memory_limit"); // get the new value
    echo "new memory: ".$new_memory;  // echo the new value
    // Will display:
    // original memory: 64
    // new memory: 128
    ?>

You have to place the ini_set('memory_limit','128M'); at the top of the file or at least before any echo.

As for me, suhosin wasn't the solution because it doesn't even appear in my phpinfo(), but this worked:

    <?php
    ini_set('memory_limit','2048M'); // set at the top of the file
    (...)
    ?>

Since Django 2.0 the ForeignKey field requires two positional arguments:

1. the model to map to
2. the on_delete argument

categorie = models.ForeignKey('Categorie', on_delete=models.PROTECT)

Here are some methods can used in on_delete

1. CASCADE

Cascade deletes. Django emulates the behavior of the SQL constraint ON DELETE CASCADE and also deletes the object containing the ForeignKey

2. PROTECT

Prevent deletion of the referenced object by raising ProtectedError, a subclass of django.db.IntegrityError.

3. DO_NOTHING

Take no action. If your database backend enforces referential integrity, this will cause an IntegrityError unless you manually add an SQL ON DELETE constraint to the database field.

you can find more about on_delete by reading the documentation.

Create the classLoader instance of the class you need, then you can access the files or resources easily. now you access path using getPath() method of that class.

 ClassLoader classLoader = getClass().getClassLoader();
 String path  = classLoader.getResource("chromedriver.exe").getPath();
 System.out.println(path);

As the other answers said, the function you need is cv2.rectangle(), but keep in mind that the coordinates for the bounding box vertices need to be integers if they are in a tuple, and they need to be in the order of (left, top) and (right, bottom). Or, equivalently, (xmin, ymin) and (xmax, ymax).

In Windows you can use a Powershell Script with CompareObject

compare-object -IncludeEqual -ExcludeDifferent -PassThru (get-content A.txt) (get-content B.txt)> MATCHING.txt | Out-Null #Find Matching Lines

CompareObject:

• IncludeEqual without -ExcludeDifferent : Everything
• ExcludeDifferent without -InclueEqual : Nothing

If you're happy to require 'active_support/core_ext', then you can use

DateTime.now.midnight # => Sat, 19 Nov 2011 00:00:00 -0800

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

Here is pythonic way to do it. This function will allow you to loop through key-value pair in all the levels. It does not save the whole thing to the memory but rather walks through the dict as you loop through it

def recursive_items(dictionary):
    for key, value in dictionary.items():
        if type(value) is dict:
            yield (key, value)
            yield from recursive_items(value)
        else:
            yield (key, value)

a = {'a': {1: {1: 2, 3: 4}, 2: {5: 6}}}

for key, value in recursive_items(a):
    print(key, value)

Prints

a {1: {1: 2, 3: 4}, 2: {5: 6}}
1 {1: 2, 3: 4}
1 2
3 4
2 {5: 6}
5 6

Enable Multidex through build.gradle of your app module

multiDexEnabled true

Same as below -

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

Then follow below steps -

1. From the Build menu -> press the Clean Project button.
2. When task completed, press the Rebuild Project button from the Build menu.
3. From menu File -> Invalidate cashes / Restart

compile is now deprecated so it's better to use implementation or api

Interesting that I didn't see a mention of UTM coordinates.

https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system.

At least if you want to add km to the same zone, it should be straightforward (in Python : https://pypi.org/project/utm/ )

utm.from_latlon and utm.to_latlon.

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

My comment is mainly in reference to point #3: under what circumstances is ON UPDATE CASCADE applicable if we're assuming that the parent key is not updateable? Here is one case.

I am dealing with a replication scenario in which multiple satellite databases need to be merged with a master. Each satellite is generating data on the same tables, so merging of the tables to the master leads to violations of the uniqueness constraint. I'm trying to use ON UPDATE CASCADE as part of a solution in which I re-increment the keys during each merge. ON UPDATE CASCADE should simplify this process by automating part of the process.

I've combine multiple answers into one working solution that results with file path

Mime type is irrelevant for the example purpose.

            Intent intent;
            if(Build.VERSION.SDK_INT >= 19){
                intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
                intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, false);
                intent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
            }else{
                intent = new Intent(Intent.ACTION_GET_CONTENT);
            }
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            intent.setType("application/octet-stream");
            if(isAdded()){
                startActivityForResult(intent, RESULT_CODE);

In my case the problem was that I had outdated django-stronghold installed (0.2.9). And even though in the code I had:

from django.urls import reverse

I still encountered the error. After I upgraded the version to django-stronghold==0.4.0 the problem disappeard.

The proper way to do this is to use dispatch_async in the main_queue, as I did in the following code

dispatch_async(dispatch_get_main_queue(), {
    (self.delegate as TBGQRCodeViewController).displayQRCode(receiveAddr, withAmountInBTC:amountBTC)
})

If issue remains even after updating dependency version, then delete everything present under
C:\Users\[your_username]\.m2\repository\com\fasterxml

And, make sure following dependencies are present:

            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>

Sometimes it is just easier to start over... I apologize if there is any typo, I haven't had the time to test it thoroughly.

movdir = r"C:\Scans"
basedir = r"C:\Links"
# Walk through all files in the directory that contains the files to copy
for root, dirs, files in os.walk(movdir):
    for filename in files:
        # I use absolute path, case you want to move several dirs.
        old_name = os.path.join( os.path.abspath(root), filename )

        # Separate base from extension
        base, extension = os.path.splitext(filename)

        # Initial new name
        new_name = os.path.join(basedir, base, filename)

        # If folder basedir/base does not exist... You don't want to create it?
        if not os.path.exists(os.path.join(basedir, base)):
            print os.path.join(basedir,base), "not found" 
            continue    # Next filename
        elif not os.path.exists(new_name):  # folder exists, file does not
            shutil.copy(old_name, new_name)
        else:  # folder exists, file exists as well
            ii = 1
            while True:
                new_name = os.path.join(basedir,base, base + "_" + str(ii) + extension)
                if not os.path.exists(new_name):
                   shutil.copy(old_name, new_name)
                   print "Copied", old_name, "as", new_name
                   break 
                ii += 1

If you don't want to leave base R, here's a fairly succinct and expressive possibility:

x <- q.data$string
lengths(regmatches(x, gregexpr("a", x)))
# [1] 2 1 0

Look at the example:

    <select class="element select small" id="account_name" name="account_name"> 

        <option value="" selected="selected">Please Select</option>           
        <option value="paypal" >Paypal</option>
        <option value="webmoney" >Webmoney</option>

    </select>

 <script type="text/javascript">

        $(document).ready(function(){ 
             $('#account_name').change(function(){
               alert($(this).val());                                                          
             });
        });
 </script>

I came here and followed above answer. But mismatch in the Order of data type caused an error. The below description from another answer will come handy.

Are the results above the same as the sequence of columns in your table? because oracle is strict in column orders. this example below produces an error:

create table test1_1790 (
col_a varchar2(30),
col_b number,
col_c date);

create table test2_1790 (
col_a varchar2(30),
col_c date,
col_b number);

select * from test1_1790
union all
select * from test2_1790;

ORA-01790: expression must have same datatype as corresponding expression

As you see the root cause of the error is in the mismatching column ordering that is implied by the use of * as column list specifier. This type of errors can be easily avoided by entering the column list explicitly:

select col_a, col_b, col_c from test1_1790 union all select col_a, col_b, col_c from test2_1790; A more frequent scenario for this error is when you inadvertently swap (or shift) two or more columns in the SELECT list:

select col_a, col_b, col_c from test1_1790
union all
select col_a, col_c, col_b from test2_1790;

OR if the above does not solve your problem, how about creating an ALIAS in the columns like this: (the query is not the same as yours but the point here is how to add alias in the column.)

SELECT id_table_a, 
       desc_table_a, 
       table_b.id_user as iUserID, 
       table_c.field as iField
UNION
SELECT id_table_a, 
       desc_table_a, 
       table_c.id_user as iUserID, 
       table_c.field as iField

I thought it would be useful to compare the timings of the different solutions presented here. For this I used my own library simple_benchmark:

So indeed for this case the solution from Denis Otkidach is fastest.

Some of the approaches also exhibit a much steeper curve, these are the approaches that scale quadratic with the number of elements (Alex Martellis first solution, wjandrea and both of Xavier Decorets solutions). Also important to mention is that the pandas solution from Keiku has a very big constant factor. But for larger lists it almost catches up with the other solutions.

And in case the duplicate is at the first position. This is useful to see which solutions are short-circuiting:

Here several approaches don't short-circuit: Kaiku, Frank, Xavier_Decoret (first solution), Turn, Alex Martelli (first solution) and the approach presented by Denis Otkidach (which was fastest in the no-duplicate case).

I included a function from my own library here: iteration_utilities.all_distinct which can compete with the fastest solution in the no-duplicates case and performs in constant-time for the duplicate-at-begin case (although not as fastest).

The code for the benchmark:

from collections import Counter

In your batch file do this

set source=C:\Users\Habib\test
set destination=C:\Users\Habib\testdest\
xcopy %source% %destination% /y

If you want to copy the sub directories including empty directories then do:

xcopy %source% %destination% /E /y

If you only want to copy sub directories and not empty directories then use /s like:

xcopy %source% %destination% /s /y

Use the TABLOCKX lock hint for your transaction. See this article for more information on locking.

Here's an alternative way of tackling the problem:

Instead of trying to "fix it in post" why don't you truncate the description before the table needs to try and fit it into its columns? I did it like this:

<ng-container matColumnDef="description">
   <th mat-header-cell *matHeaderCellDef> {{ 'Parts.description' | translate }} </th>
            <td mat-cell *matCellDef="let element">
                {{(element.description.length > 80) ? ((element.description).slice(0, 80) + '...') : element.description}}
   </td>
</ng-container>

So I first check if the array is bigger than a certain length, if Yes then truncate and add '...' otherwise pass the value as is. This enables us to still benefit from the auto-spacing the table does :)

<select ng-init="somethingHere = options[0]" ng-model="somethingHere" ng-options="option.name for option in options"></select>

This would get you desired result Dude :) Cheers

To Convert file path in String to NSURL, observe the following code

var filePathUrl = NSURL.fileURLWithPath(path)

1) First you need to install a GCC Compiler for mac (Google it and install it from the net )

2) Remember the path where you are storing the C file

3) Go to Terminal and set the path

e.g- if you have saved in a new folder ProgramC in Document folder

   then type this in Terminal
    cd Document
    cd ProgramC

4) Now you can see that you are in folder where you have saved your C program (let you saved your program as Hello.c)

5) Now Compile your program

   make Hello
   ./hello

Press Ctrl+R to find and replace codes in the class where you are...

The problem is that C++ is a statically-typed language, meaning that if something is declared as a string, it's a string, and if something is declared as a double, it's a double. Unlike other languages like JavaScript or PHP, there is no way to automatically convert from a string to a numeric value because the conversion might not be well-defined. For example, if you try converting the string "Hi there!" to a double, there's no meaningful conversion. Sure, you could just set the double to 0.0 or NaN, but this would almost certainly be masking the fact that there's a problem in the code.

To fix this, don't buffer the file contents into a string. Instead, just read directly into the double:

double lol;
openfile >> lol;

This reads the value directly as a real number, and if an error occurs will cause the stream's .fail() method to return true. For example:

double lol;
openfile >> lol;

if (openfile.fail()) {
    cout << "Couldn't read a double from the file." << endl;
}

You can convert String to Timestamp:

String inDate = "01-01-1990"
DateFormat df = new SimpleDateFormat("MM-dd-yyyy");
Timestamp ts = new Timestamp(((java.util.Date)df.parse(inDate)).getTime());

The following function will return an array containing all the siblings of the given element.

function getSiblings(elem) {
    return [...elem.parentNode.children].filter(item => item !== elem);
}

Just pass the selected element into the getSiblings() function as it's only parameter.

If you are on a Windows PC, you can use WScript.exe or CScript.exe

Just keep in mind that you are not in a browser environment, so stuff like document.write or anything that relies on the window object will not work, like window.alert. Instead, you can call WScript.Echo to output stuff to the prompt.

If you want to search deleted record (Soft Deleted Record), do't user Eloquent Model Query. Instead use Db::table query e.g Instead of using Below:

$stu = Student::where('rollNum', '=', $rollNum . '-' . $nursery)->first();

Use:

$stu = DB::table('students')->where('rollNum', '=', $newRollNo)->first();

Per above, a dataset or typed dataset might be a good temorary structure which you could use to do your filtering. A SqlDataReader is meant to read the data very quickly. While you are in the while() loop you are still connected to the DB and it is waiting for you to do whatever you are doing in order to read/process the next result before it moves on. In this case you might get better performance if you pull in all of the data, close the connection to the DB and process the results "offline".

People seem to hate datasets, so the above could be done wiht a collection of strongly typed objects as well.

[xml]$xmlfile = '<xml> <Section name="BackendStatus"> <BEName BE="crust" Status="1" /> <BEName BE="pizza" Status="1" /> <BEName BE="pie" Status="1" /> <BEName BE="bread" Status="1" /> <BEName BE="Kulcha" Status="1" /> <BEName BE="kulfi" Status="1" /> <BEName BE="cheese" Status="1" /> </Section> </xml>'

foreach ($bename in $xmlfile.xml.Section.BEName) {
    if($bename.Status -eq 1){
        #Do something
    }
}

Previous answer doesn't work for me :( But it's OK like that :)

         $data = json_decode(

                  'CP1252',
                  json_encode($data)
                )
              , true)

Please Set As Below

img = cv2.imread('2015-05-27-191152.jpg',1)     // Change Flag As 1 For Color Image
                                                //or O for Gray Image So It image is 
                                                //already gray

How about this:

function array_keys_exist($searchForKeys = array(), $searchableArray) {
    $searchableArrayKeys = array_keys($searchableArray);

    return count(array_intersect($searchForKeys, $searchableArrayKeys)) == count($searchForKeys); 
}

I had the same problem what I did, I copied web.dll from Microsoft.NET framework, then paste in root of project, then add dll refrence to app, it worked

Checkout the Ruby CGI class. There are methods to encode and decode HTML as well as URLs.

CGI::escapeHTML('Usage: foo "bar" <baz>')
# => "Usage: foo &quot;bar&quot; &lt;baz&gt;"

Another possible option, depending on what you need the array for:

$array = array('lastname', 'email', 'phone');
echo json_encode($array);

This will put '[' and ']' around the string, which you may or may not want.

I struggled with this problem for a while myself. It turned out that cmake was looking for Boost library files using Boost's naming convention, in which the library name is a function of the compiler version used to build it. Our Boost libraries were built using GCC 4.9.1, and that compiler version was in fact present on our system; however, GCC 4.4.7 also happened to be installed. As it happens, cmake's FindBoost.cmake script was auto-detecting the GCC 4.4.7 installation instead of the GCC 4.9.1 one, and thus was looking for Boost library files with "gcc44" in the file names, rather than "gcc49".

The simple fix was to force cmake to assume that GCC 4.9 was present, by setting Boost_COMPILER to "-gcc49" in CMakeLists.txt. With this change, FindBoost.cmake looked for, and found, my Boost library files.

As DSM mentions, tuple's are immutable, but even for lists, a more elegant solution is to use filter:

tupleX = filter(str.isdigit, tupleX)

or, if condition is not a function, use a comprehension:

tupleX = [x for x in tupleX if x > 5]

if you really need tupleX to be a tuple, use a generator expression and pass that to tuple:

tupleX = tuple(x for x in tupleX if condition)

i mentioned in the below where i have mentioned the custom filter also , how to call these filter which is having two parameters

countryApp.filter('reverse', function() {
    return function(input, uppercase) {
        var out = '';
        for (var i = 0; i < input.length; i++) {
            out = input.charAt(i) + out;
        }
        if (uppercase) {
            out = out.toUpperCase();
        }
        return out;
    }
});

and from the html using the template we can call that filter like below

<h1>{{inputString| reverse:true }}</h1>

here if you see , the first parameter is inputString and second parameter is true which is combined with "reverse' using the : symbol

Here is a simple Windows bat file to split incoming file into 50 parts. Each part has length 1 minute. Sorry for such dumb script. I hope it is better to have a dumb windows script instead of do not have it at all. Perhaps it help someone. (Based on "bat file for loop" from this site.)

set var=0
@echo off
:start
set lz=
if %var% EQU 50 goto end
if %var% LEQ 9 set lz=0
echo part %lz%%var%
ffmpeg -ss 00:%lz%%var%:00 -t 00:01:00 -i %1 -acodec copy -vcodec copy %2_%lz%%var%.mp4

Print the last json error when debugging.

json_decode( $so, true, 9 );
$json_errors = array(
    JSON_ERROR_NONE => 'No error has occurred',
    JSON_ERROR_DEPTH => 'The maximum stack depth has been exceeded',
    JSON_ERROR_CTRL_CHAR => 'Control character error, possibly incorrectly encoded',
    JSON_ERROR_SYNTAX => 'Syntax error',
);
 echo 'Last error : ', $json_errors[json_last_error()], PHP_EOL, PHP_EOL;

This appends the output to all.txt

See §6.7.9 Initialization:

21 If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

So, yes both of them work. Note that in C99 a new way of initialization, called designated initialization can be used too:

myStruct _m1 = {.c2 = 0, .c1 = 1};

As Herman pointed out, you can get the index and element from each iteration.

{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}

Working example:

package main

import (
    "html/template"
    "os"
)

type EntetiesClass struct {
    Name string
    Value int32
}

// In the template, we use rangeStruct to turn our struct values
// into a slice we can iterate over
var htmlTemplate = `{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}`

func main() {
    data := map[string][]EntetiesClass{
        "Yoga": {{"Yoga", 15}, {"Yoga", 51}},
        "Pilates": {{"Pilates", 3}, {"Pilates", 6}, {"Pilates", 9}},
    }

    t := template.New("t")
    t, err := t.Parse(htmlTemplate)
    if err != nil {
        panic(err)
    }

    err = t.Execute(os.Stdout, data)
    if err != nil {
        panic(err)
    }

}

Output:

Pilates
3
6
9

Yoga
15

I faced the same issues. To solve this, I used export PYTHONPATH="$PWD". However, in this case, you will need to modify imports in your Scripts dir depending on the below:

Case 1: If you are in the user_management dir, your scripts should use this style from Modules import LDAPManager to import module.

Case 2: If you are out of the user_management 1 level like main, your scripts should use this style from user_management.Modules import LDAPManager to import modules.

Convert the string to an integer base 16 then to hexadecimal.

print hex(int(string, base=16))

These are built-in functions.

http://docs.python.org/2/library/functions.html#int

Example

>>> string = 'AA'
>>> _int = int(string, base=16)
>>> _hex = hex(_int)
>>> print _int
170
>>> print _hex
0xaa

This modification of a_horse_with_no_name's answer will give you the blocking queries in addition to just the blocked sessions:

SELECT
    activity.pid,
    activity.usename,
    activity.query,
    blocking.pid AS blocking_id,
    blocking.query AS blocking_query
FROM pg_stat_activity AS activity
JOIN pg_stat_activity AS blocking ON blocking.pid = ANY(pg_blocking_pids(activity.pid));

Your project has to have a builder set for it. If there is not one Eclipse will default to Ant. Which you can use you have to create an Ant build file, which you can Google how to do. It is rather involved though. This is not required to run locally in Eclipse though. If your class is run-able. It looks like yours is, but we can not see all of it.

If you look at your project build path do you have an output folder selected? If you check that folder have the compiled class files been put there? If not the something is not set in Eclpise for it to know to compile. You might check to see if auto build is set for your project.

Or, in order to avoid modifying slowFunc (say you don't have access to the source code for instance):

var source = new CancellationTokenSource(); //original code
source.Token.Register(CancelNotification); //original code
source.CancelAfter(TimeSpan.FromSeconds(1)); //original code
var completionSource = new TaskCompletionSource<object>(); //New code
source.Token.Register(() => completionSource.TrySetCanceled()); //New code
var task = Task<int>.Factory.StartNew(() => slowFunc(1, 2), source.Token); //original code

//original code: await task;  
await Task.WhenAny(task, completionSource.Task); //New code

You can also use nice extension methods from https://github.com/StephenCleary/AsyncEx and have it looks as simple as:

await Task.WhenAny(task, source.Token.AsTask());

Use this:

SELECT * 
FROM tablename 
ORDER BY priority desc, FIELD(name, "core")

To build on AlfredBr's answer, if you hid some of your columns, you can use the following to auto-size all columns and then just have the last visible column fill the empty space:

myDgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
myDgv.Columns.GetLastColumn(DataGridViewElementStates.Visible, DataGridViewElementStates.None).AutoSizeMode = 
    DataGridViewAutoSizeColumnMode.Fill;

It is not exactly for Xcode5 but this question links people who want to check where are provisioning profiles:
Following documentation https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistributionGuide/MaintainingCertificates/MaintainingCertificates.html

1. Choose Xcode > Preferences.
2. Click Accounts at the top of the window.
3. Select the team you want to view, and click View Details. In the dialog that appears, view your signing identities and provisioning profiles. If a Create button appears next to a certificate, it hasn’t been created yet. If a Download button appears next to a provisioning profile, it’s not on your Mac.

Ten you can start context menu on each profile and click "Show in Finder" or "Move to Trash".

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

Absolutely! Just use

<tr style="outline: thin solid">

on which ever row you like. Here's a fiddle.

Of course, as people have mentioned, you can do this via an id, or class, or some other means if you wish.

arrowdodger's answer is correct and preferred on many occasions. I would simply like to add an alternative to his answer:

You could add an "imported" library target, instead of a link-directory. Something like:

# Your-external "mylib", add GLOBAL if the imported library is located in directories above the current.
add_library( mylib SHARED IMPORTED )
# You can define two import-locations: one for debug and one for release.
set_target_properties( mylib PROPERTIES IMPORTED_LOCATION ${CMAKE_BINARY_DIR}/res/mylib.so )

And then link as if this library was built by your project:

TARGET_LINK_LIBRARIES(GLBall mylib)

Such an approach would give you a little more flexibility: Take a look at the add_library( ) command and the many target-properties related to imported libraries.

I do not know if this will solve your problem with "updated versions of libs".

For IPv4 addresses, you can use VARCHAR to store them as strings, but also look into storing them as long integesrs INT(11) UNSIGNED. You can use MySQL's INET_ATON() function to convert them to integer representation. The benefit of this is it allows you to do easy comparisons on them, like BETWEEN queries

INET_ATON() MySQL function

I am not sure did you see this list of MS SQL Modules for Node JS

Share your experience after using one if possible .

Good Luck

Use the isSelected method.

You can also use an ItemListener so you'll be notified when it's checked or unchecked.

I am going to drop in my two cents for what I use opcache.

I have made an extensive framework with a lot of fields and validation methods and enums to be able to talk to my database.

Without opcache

When using this script without opcache and I push 9000 requests in 2.8 seconds to the apache server it maxes out at 90-100% cpu for 70-80 seconds until it catches up with all the requests.

Total time taken: 76085 milliseconds(76 seconds)

With opcache enabled

With opcache enabled it runs at 25-30% cpu time for about 25 seconds and never passes 25% cpu use.

Total time taken: 26490 milliseconds(26 seconds)

I have made an opcache blacklist file to disable the caching of everything except the framework which is all static and doesnt need changing of functionality. I choose explicitly for just the framework files so that I could develop without worrying about reloading/validating the cache files. Having everything cached saves a second on the total of the requests 25546 milliseconds

This significantly expands the amount of data/requests I can handle per second without the server even breaking a sweat.

If you're running in a Linux environment, open the file /etc/hosts.allow add the following line

ALL

Wildcards

Also check the /etc/hostname and /etc/host to see if there might be something wrong there.

I had to change my / etc / host from

127.0.0.1 localhost
127.0.1.1 AMK

to

127.0.0.1 localhost
127.0.0.1 AMK

also wrote in ALL in the file /etc/hosts.allow which was previously completely empty

Now everything works

do not know how safe it is. you have to read more about possible options for /etc/hosts.allow to do something that requires a touch of security.

The cc and cxx is located inside /Applications/Xcode.app. This should find the right paths

export CXX=`xcrun -find c++`
export CC=`xcrun -find cc`

Please provide the exact image name(including the extension) as specified in the images folder. A mismatch can trigger this exception.

I use this mnemonic:

• Single quotes are for strings (one thing)
• Double quotes are for tables names and column names (two things)

This is not 100% correct according to the specs, but this mnemonic helps me (human being).

This is an other way to solve your problem. So please check out below solution. Hope it will help you.

let str = "{\"names\": [\"Bob\", \"Tim\", \"Tina\"]}"
let data = str.data(using: String.Encoding.utf8, allowLossyConversion: false)!
do {
    let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
    if let names = json["names"] as? [String] {
        print(names)
    }
} catch let error as NSError {
    print("Failed to load: \(error.localizedDescription)")
}

If you're going to nest ternary operators, I believe you'd want to do something like this:

   var audience = (countrycode == 'eu') ? 'audienceEU' :
                  (countrycode == 'jp') ? 'audienceJP' :
                  (countrycode == 'cn') ? 'audienceCN' :
                  'audienceUS';

It's a lot more efficient to write/read than:

var audience = 'audienceUS';
if countrycode == 'eu' {
   audience = 'audienceEU';
} else if countrycode == 'jp' {
   audience = 'audienceJP';
} else if countrycode == 'cn' {
   audience = 'audienceCN';
}

As with all good programming, whitespace makes everything nice for people who have to read your code after you're done with the project.

I tried to to get these suggestions to work for a textblock, but couldn't get it to work. I even tried to get it to work from the designer. (Look in Layout and expand the list by clicking the down-arrow "V" at the bottom) I tried setting the scrollviewer to Visible and then Auto, but it still wouldn't work.

I eventually gave up and changed the TextBlock to a TextBox with the Readonly attribute set, and it worked like a charm.

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

You can also run the follow command to reset the query cache.

RESET QUERY CACHE

I wish #pragma once (or something like it) had been in the standard. Include guards aren't a real big deal (but they do seem to be a little difficult to explain to people learning the language), but it seems like a minor annoyance that could have been avoided.

In fact, since 99.98% of the time, the #pragma once behavior is the desired behavior, it would have been nice if preventing multiple inclusion of a header was automatically handled by the compiler, with a #pragma or something to allow double including.

But we have what we have (except that you might not have #pragma once).

2020 solution via Material Design Components for Android:

Add Material Components to your gradle setup:

Look for latest version from here: https://maven.google.com/

implementation 'com.google.android.material:material:1.1.0'

or if you havent updated to using AndroidX libs, you can add it this way:

implementation 'com.android.support:design:28.0.0'

Then

<com.google.android.material.textfield.TextInputLayout
    android:layout_width="match_parent"

As discussed here Material design docs

You can use the util library that comes with nodejs to get a promise from the exec command and can use that output as you need. Use restructuring to store the stdout and stderr in variables.

const util = require('util');
const exec = util.promisify(require('child_process').exec);

async function lsExample() {
  const {
    stdout,
    stderr
  } = await exec('ls');
  console.log('stdout:', stdout);
  console.error('stderr:', stderr);
}
lsExample();

You can use the varStatus attribute like this:-

<c:forEach var="categoryName" items="${categoriesList}" varStatus="myIndex">

myIndex.index will give you the index. Here myIndex is a LoopTagStatus object.

Hence, you can send that to your javascript method like this:-

<a onclick="getCategoryIndex(${myIndex.index})" href="#">${categoryName}</a>

The disapproval of tail here based on speed alone doesn't really seem to emphasize that part of the slower speed comes from the fact that tail is safer to work with, if you don't for sure that the length of x will exceed n, the number of elements you want to subset out:

x <- 1:10
tail(x, 20)
# [1]  1  2  3  4  5  6  7  8  9 10
x[length(x) - (0:19)]
#Error in x[length(x) - (0:19)] : 
#  only 0's may be mixed with negative subscripts

Tail will simply return the max number of elements instead of generating an error, so you don't need to do any error checking yourself. A great reason to use it. Safer cleaner code, if extra microseconds/milliseconds don't matter much to you in its use.

nullptr is always a pointer type. 0 (aka. C's NULL bridged over into C++) could cause ambiguity in overloaded function resolution, among other things:

f(int);
f(foo *);

You can easily pass the path of the image to retrieve the base64 string

public static string ImageToBase64(string _imagePath)
    {
        string _base64String = null;

        using (System.Drawing.Image _image = System.Drawing.Image.FromFile(_imagePath))
        {
            using (MemoryStream _mStream = new MemoryStream())
            {
                _image.Save(_mStream, _image.RawFormat);
                byte[] _imageBytes = _mStream.ToArray();
                _base64String = Convert.ToBase64String(_imageBytes);

                return "data:image/jpg;base64," + _base64String;
            }
        }
    }

Hope this will help.

Yes. The VBA equivalent of AltEnter is to use a linebreak character:

ActiveCell.Value = "I am a " & Chr(10) & "test"

Note that this automatically sets WrapText to True.

Proof:

Sub test()
Dim c As Range
Set c = ActiveCell
c.WrapText = False
MsgBox "Activcell WrapText is " & c.WrapText
c.Value = "I am a " & Chr(10) & "test"
MsgBox "Activcell WrapText is " & c.WrapText
End Sub

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

On Linux, with NuGet CLI, the commands are similar. To install my.nupkg, run

nuget add -Source some/directory my.nupkg

Then run dotnet restore from that directory

dotnet restore --source some/directory Project.sln

or add that directory as a NuGet source

nuget sources Add -Name MySource -Source some/directory

and then tell msbuild to use that directory with /p:RestoreAdditionalSources=MySource or /p:RestoreSources=MySource. The second switch will disable all other sources, which is good for offline scenarios, for example.

You might just have to install the packages.

yum install php-pdo php-mysqli

After they're installed, restart Apache.

httpd restart

or

apachectl restart

To test multiple variables with one single value: if 1 in {a,b,c}:

To test multiple values with one variable: if a in {1, 2, 3}:

use setAttribute() and removeAttribute()

function disbtn(e) { 
    if ( someCondition == true ) {
       document.getElementById('btn1').setAttribute("disabled","disabled");
    } else {
       document.getElementById('btn1').removeAttribute("disabled");
    }
}

There are a few. I was looking into MBTrading for a friend. I didn't get too far, as my friend lost interest. Seemed relatively straigt forward with a C# and VB.Net SDK. They had some docs and everything. This was ~6 months ago, so it may be better (or worse) by now.

IIRC, you can create a demo account for free. I don't remember all the details, but it let you connect to their test server and pull quotes and make fake trades and such to get your software fine tuned.

Don't know much about cost for an actual account or anything.

You could use CONCAT, and the numeric argument of it is converted to its equivalent binary string form.

select t2.* 
from t1 join t2 
on t2.url=CONCAT('site.com/path/%', t1.id, '%/more') where t1.id > 9000
