"hard coding" means putting something into your source code. If you are not hard coding, then you do something like prompting the user for the data, or allow the user to put the data on the command line, or something like that.

So, to hard code the location of the file as being on the C: drive, you would just put the pathname of the file all together in your source code.

Here is an example.

int main()
{
    const char *filename = "C:\\myfile.txt";

    printf("Filename is: %s\n", filename);
}

The file name is "hard coded" as: C:\myfile.txt

The reason the backslash is doubled is because backslashes are special in C strings.

See here for a good explanation of how your dependent modules won't be reloaded and the effects that can have:

http://pyunit.sourceforge.net/notes/reloading.html

The way pyunit solved it was to track dependent modules by overriding __import__ then to delete each of them from sys.modules and re-import. They probably could've just reload'ed them, though.

I would not recommend installing CUDA/cuDNN on the host if you can use docker. Since at least CUDA 8 it has been possible to "stand on the shoulders of giants" and use nvidia/cuda base images maintained by NVIDIA in their Docker Hub repo. Go for the newest and biggest one (with cuDNN if doing deep learning) if unsure which version to choose.

A starter CUDA container:

mkdir ~/cuda11
cd ~/cuda11

echo "FROM nvidia/cuda:11.0-cudnn8-devel-ubuntu18.04" > Dockerfile
echo "CMD [\"/bin/bash\"]" >> Dockerfile

docker build --tag mirekphd/cuda11 .

docker run --rm -it --gpus 1 mirekphd/cuda11 nvidia-smi

Sample output:

(if nvidia-smi is not found in the container, do not try install it there - it was already installed on thehost with NVIDIA GPU driver and should be made available from the host to the container system if docker has access to the GPU(s)):

Prerequisites

1. Appropriate NVIDIA driver with the latest CUDA version support to be installed first on the host (download it from NVIDIA Driver Downloads and then mv driver-file.run driver-file.sh && chmod +x driver-file.sh && ./driver-file.sh). These are have been forward-compatible since CUDA 10.1.

2. GPU access enabled in docker by installing sudo apt get update && sudo apt get install nvidia-container-toolkit (and then restarting docker daemon using sudo systemctl restart docker).

I removed the bugs in above code and got below results: Also I am unsure given how NetSerializer requires you to register the types you are serializing, what kind of compatibility or performance differences that could potentially make.

If JSON conventions are enough for the unescaped strings you want to get escaped and you already use Newtonsoft.Jsonin your project (it has a pretty large overhead) you may use this package like the following:

using System;
using Newtonsoft.Json;

public class Program
{
    public static void Main()
    {
    Console.WriteLine(ToLiteral( @"abc\n123") );
    }

    private static string ToLiteral(string input){
        return JsonConvert.DeserializeObject<string>("\"" + input + "\"");
    }
}

As far as I am aware, the MSVCRxxx.dlls are in %SystemRoot%\System32 (usually C:\Windows\System32).

The xxx refers to the version of the MS Visual C Runtime (hence MSVCR...)

However, the complication seems to be that the xxx version is not the same as the two digits of the year "version".

For example, Visual C Runtime 2013 yields MSVCR120.dll and "...Runtime 2012" yields MSVCR110.dll. And then Microsoft packages these as vcredist_x86.exe or vcredist_x64.exe, seemingly irrespective of the xxx version or the Visual Studio version number (2012, 2013 etc) - confused? You have every right to be!

So, firstly, you need to determine whether you need 32 bit, 64 bit or even both (some PHP distributions apparently do need both), then download the relevant vcredist... for the bits AND for the Visual Studio version. As far as I can tell, the only way to tell which vcredist... you have is to start to install it. Recent versions give an intro screen that quotes the Visual Studio version and the xxx version. I have renamed by vcredists to something like vcredist_x64_2012_V11.exe.

[EDIT] Forgot to add earlier that if you are simply looking to "install" the missing DLL (as opposed to resolve some bigger set of issues), then you probably won't do any harm by simply installing the relevant vcredist for your architecture (32 bit, 64 bit) and "missing" version.

A couple of answers that should work above but this is how i would write it.

Also, i wouldn't declare controllers inside templates. It's better to declare them on your routes imo.

add-text.tpl.html

<div ng-controller="myController">
    <form ng-submit="addText(myText)">
        <input type="text" placeholder="Let's Go" ng-model="myText">
        <button type="submit">Add</button>
    </form>
    <ul>
        <li ng-repeat="text in arrayText">{{ text }}</li>
    </ul>
</div>

app.js

(function() {

    function myController($scope) {
        $scope.arrayText = ['hello', 'world'];
        $scope.addText = function(myText) {
             $scope.arrayText.push(myText);     
        };
    }

    angular.module('app', [])
        .controller('myController', myController);

})();

To remove a MenuItem from an ASP.net NavigationMenu by Value:

public static void RemoveMenuItemByValue(MenuItemCollection items, String value)
{
   MenuItem itemToRemove = null;

   //Breadth first, look in the collection
   foreach (MenuItem item in items)
   {
      if (item.Value == value)
      {
          itemToRemove = item;
          break;
      }
   }

   if (itemToRemove != null)
   {
      items.Remove(itemToRemove);
      return;
   }


   //Search children
   foreach (MenuItem item in items)
   {
       RemoveMenuItemByValue(item.ChildItems, value);
   }
}

and helper extension:

public static RemoveMenuItemByValue(this NavigationMenu menu, String value)
{
   RemoveMenuItemByValue(menu.Items, value);
}

and sample usage:

navigationMenu.RemoveMenuItemByValue("UnitTests");

One simple solution.

In your Model

protected $rules = [
    'email_address' => 'sometimes|required|email|unique:users',
    ..
];

In your Controller, action:update

...
$rules = User::$rules;
$rules['email_address'] = $rules['email_address'] . ',id,' . $id;
$validationCertificate  = Validator::make($input, $rules); 

The simplest is to do a PivotChart. Select your array of dates (with a header) and create a new Pivot Chart (Insert / PivotChart / Ok) Then on the field list window, drag and drop the date column in the Axis list first and then in the value list first.

Step 1:

Step 2:

The only way I can think of for short texts like "MENU" is to put every single letter in a span and justify them in a container afterwards. Like this:

<div class="menu-burger">
  <span></span>
  <span></span>
  <span></span>
  <div>
    <span>M</span>
    <span>E</span>
    <span>N</span>
    <span>U</span>
  </div>
</div>

And then the CSS:

.menu-burger {
  width: 50px;
  height: 50px;
  padding: 5px;
}

...

.menu-burger > div {
  display: flex;
  justify-content: space-between;
}

C:\xampp\mysql\bin\mysql -u root -p testdatabase < C:\Users\Juan\Desktop\databasebackup.sql

That worked for me to import 400MB file into my database.

First try this code inside AndroidManifest

  <application>
       
    <uses-library
        android:name="org.apache.http.legacy"
        android:required="false" />
 </application>

If this code works, so fine. But if not. Try this code from which class you want to pass the data or uri.

Intent window = new Intent(getApplicationContext(), Browser.class);
window.putExtra("LINK", "http://www.yourwebsite.com");
startActivity(window);

Using docker-compose exec -T fixed the problem for me via Jenkins

docker-compose exec -T containerName php script.php

I am using Protractor with directConnect. Disabling the "--no-sandbox" option fixed the issue for me.

// Capabilities to be passed to the webdriver instance.
capabilities: {
  'directConnect': true,
  'browserName': 'chrome',
  chromeOptions: {
      args: [
        //"--headless",
        //"--hide-scrollbars",
        "--disable-software-rasterizer",
        '--disable-dev-shm-usage',
        //"--no-sandbox",
        "incognito",
        "--disable-gpu",
        "--window-size=1920x1080"]
  }
},

Thunderbird supports html-body: mailto:[email protected]?subject=Me&html-body=<b>ME</b>

Add in ~/.bash_profile for adding, committing and pushing with one command put:

function g() { git commit -a -m "$*"; git push; }

Usage:

g your commit message
g your commit message 'message'

No quotes are needed although you can't use semicolons or parenthesis in your commit messages (single quotes are allowed). If you want to any of these just simply put double quotes in you message, e.g.:

g "your commit message; (message)"

To create a comment in your message do:

g "your commit message:
> your note"

There's also a function for adding and committing in a similar way:

function c() { git add --all; git commit -m "$*"; }

Works exactly the same way that g function and has the same constraints. Just put c instead. E.g.

c your commit message

You can also add an alias for pushing to the remote:

alias p='git push'

Usage:

p

That amounts into 2 letters, c and p you use while working with your git repository. Or you can use g instead to do it all with only one letter.

Full list of aliases and functions: https://gist.github.com/matt360/0c5765d6f0579a5aa74641bc47ae50ac

Here is a little something I cooked up today. Seems to work for me. Basically you override the Add method in your base namespace to do a check and then call the base's Add method in order to actually add it. Hope this works for you

using System;
using System.Collections.Generic;
using System.Collections;

namespace Main
{
    internal partial class Dictionary<TKey, TValue> : System.Collections.Generic.Dictionary<TKey, TValue>
    {
        internal new virtual void Add(TKey key, TValue value)
        {   
            if (!base.ContainsKey(key))
            {
                base.Add(key, value);
            }
        }
    }

    internal partial class List<T> : System.Collections.Generic.List<T>
    {
        internal new virtual void Add(T item)
        {
            if (!base.Contains(item))
            {
                base.Add(item);
            }
        }
    }

    public class Program
    {
        public static void Main()
        {
            Dictionary<int, string> dic = new Dictionary<int, string>();
            dic.Add(1,"b");
            dic.Add(1,"a");
            dic.Add(2,"c");
            dic.Add(1, "b");
            dic.Add(1, "a");
            dic.Add(2, "c");

            string val = "";
            dic.TryGetValue(1, out val);

            Console.WriteLine(val);
            Console.WriteLine(dic.Count.ToString());


            List<string> lst = new List<string>();
            lst.Add("b");
            lst.Add("a");
            lst.Add("c");
            lst.Add("b");
            lst.Add("a");
            lst.Add("c");

            Console.WriteLine(lst[2]);
            Console.WriteLine(lst.Count.ToString());
        }
    }
}

If your software uses a ProxySelector (for example for using a PAC-script instead of a static host/port) and your HTTPComponents is version 4.3 or above then you can use your ProxySelector for your HttpClient like this:

ProxySelector myProxySelector = ...;
HttpClient myHttpClient = HttpClientBuilder.create().setRoutePlanner(new SystemDefaultRoutePlanner(myProxySelector))).build();

And then do your requests as usual:

HttpGet myRequest = new HttpGet("/");
myHttpClient.execute(myRequest);

Steps to debug coredump using GDB:

Some generic help:

gdb start GDB, with no debugging les

gdb program begin debugging program

gdb program core debug coredump core produced by program

gdb --help describe command line options

1. First of all, find the directory where the corefile is generated.

2. Then use ls -ltr command in the directory to find the latest generated corefile.

3. To load the corefile use

   gdb binary path of corefile
   

   This will load the corefile.

4. Then you can get the information using the bt command.

   For a detailed backtrace use bt full.

5. To print the variables, use print variable-name or p variable-name

6. To get any help on GDB, use the help option or use apropos search-topic

7. Use frame frame-number to go to the desired frame number.

8. Use up n and down n commands to select frame n frames up and select frame n frames down respectively.

9. To stop GDB, use quit or q.

You can either use:

<button onclick="window.history.back()">Back</button>

or..

<button onclick="window.history.go(-1)">Back</button>

The difference, of course, is back() only goes back 1 page but go() goes back/forward the number of pages you pass as a parameter, relative to your current page.

Try the code below:

Batchfile.bat:

cd c:\batchfilepath
net stop "SQL Server Reporting Services (MSSQLSERVER)" 
timeout /t 10
net start "SQL Server Reporting Services (MSSQLSERVER)"

     f.setLayout(null);

It happens to me sometimes, I always fixed that with "mvn eclipse:clean" command to clean old properties and then run mvn eclipse:eclipse -Dwtpversion=2.0 (for web project of course). There are some old properties saved so eclipse is confused sometimes.

Why do most answers here assume that all data needs to be deleted, reformatted, and then restart Hadoop? How do we know namenode is not progressing, but taking lots of time. It will do this when there is a large amount of data in HDFS. Check progress in logs before assuming anything is hung or stuck.

$ [kadmin@hadoop-node-0 logs]$ tail hadoop-kadmin-namenode-hadoop-node-0.log

This was after nearly an hour of waiting on a particular system. It is still progressing each time I look at it. Have patience with Hadoop when bringing up the system and check logs before assuming something is hung or not progressing.

This will take care of names like "Firstname Z. Lastname" and "First Z Last"

I've done something like before using the JavaScript serialization class:

using System.Web.Script.Serialization;

And:

JavaScriptSerializer jss = new JavaScriptSerializer();

string output = jss.Serialize(ListOfMyObject);
Response.Write(output);
Response.Flush();
Response.End();

nanoid achieves exactly the same thing that you want.

Example usage:

const { nanoid } = require("nanoid")

console.log(nanoid())
//=> "n340M4XJjATNzrEl5Qvsh"

If you want to install apk from your aab to your device for testing purpose then you need to edit the configuration before running it on the connected device.

1. Go to Edit Configurations
   
2. Select the Deploy dropdown and change it from "Default apk" to "APK from app bundle".
3. Apply the changes and then run it on the device connected. Build time will increase after making this change.

This will install an apk directly on the device connected from the aab.

I think the other answers miss one important detail regarding the property name to use in the EL expression. The rules for converting from the method names to property names are specified in 'Introspector.decpitalize` which is part of the java bean standard:

This normally means converting the first character from upper case to lower case, but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone.

Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "URL".

So in your case the JSTL code should look like the following, note the capital 'P':

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

<?php
$str = 'bla_string_bla_bla_bla';
echo preg_replace('/bla_/', '', $str, 1); 
?>

git log --grep="Build 0051"

should do the trick

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

Perhaps you are looking for a context manager?

>>> class Foo(object):
...   def __init__(self):
...     self.bar = None
...   def __enter__(self):
...     if self.bar != 'open':
...       print 'opening the bar'
...       self.bar = 'open'
...   def __exit__(self, type_, value, traceback):
...     if self.bar != 'closed':
...       print 'closing the bar', type_, value, traceback
...       self.bar = 'close'
... 
>>> 
>>> with Foo() as f:
...     # oh no something crashes the program
...     sys.exit(0)
... 
opening the bar
closing the bar <type 'exceptions.SystemExit'> 0 <traceback object at 0xb7720cfc>

Using groupby you could split into two dataframes like

In [1047]: df1, df2 = [x for _, x in df.groupby(df['Sales'] < 30)]

In [1048]: df1
Out[1048]:
   A  Sales
2  7     30
3  6     40
4  1     50

In [1049]: df2
Out[1049]:
   A  Sales
0  3     10
1  4     20

My way is to always Redirect::back() or Redirect::to():

Redirect::back()->with('message', 'error|There was an error...');

Redirect::back()->with('message', 'message|Record updated.');

Redirect::to('/')->with('message', 'success|Record updated.');

I have a helper function to make it work for me, usually this is in a separate service:

function displayAlert()
{
      if (Session::has('message'))
      {
         list($type, $message) = explode('|', Session::get('message'));

         $type = $type == 'error' : 'danger';
         $type = $type == 'message' : 'info';

         return sprintf('<div class="alert alert-%s">%s</div>', $type, message);
      }

      return '';
}

And in my view or layout I just do

{{ displayAlert() }}

The Apache module PHP version might for some odd reason not be picking up the php.ini file as the CLI version I'd suggest having a good look at:

• Any differences in the .ini files that differ between php -i and phpinfo() via a web page*
• If there are no differences then to look at the permissions of mysql.so and the .ini files but I think that Apache parses these as the root user

To be really clear here, don't go searching for php.ini files on the file system, have a look at what PHP says that it's looking at

 var miobj = [
  {"padreid":"0", "sw":"0", "dtip":"UNO", "datos":[]},
  {"padreid":"1", "sw":"0", "dtip":"DOS", "datos":[]}
 ];
 alert(miobj.length) //=== 2

but

 alert(miobj[0].length) //=== undefined

this function is very good

Object.prototype.count = function () {
    var count = 0;
    for(var prop in this) {
        if(this.hasOwnProperty(prop))
            count = count + 1;
    }
    return count;
}

alert(miobj.count()) // === 2
alert(miobj[0].count()) // === 4

One should note that in the case of array indexing, array[~i] amounts to reversed_array[i]. It can be seen as indexing starting from the end of the array:

[0, 1, 2, 3, 4, 5, 6, 7, 8]
    ^                 ^
    i                ~i

Example to get the last input element:

document.querySelector(".groups-container >div:last-child input")

There are four options here:

1. Get virtualenv set up. Each virtual environment you create will automatically have pip.

2. Get pip set up globally.

3. Learn how to install Python packages manually—in most cases it's as simple as download, unzip, python setup.py install, but not always.

4. Use Christoph Gohlke's binary installers.

Glorious, Pure-HTML/CSS Solution

In 2019 with CSS3 you can do this without Javascript at all. I frequently make sticky headers like this:

body {_x000D_
  overflow-y: auto;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
header {_x000D_
  position: sticky; /* Allocates space for the element, but moves it with you when you scroll */_x000D_
  top: 0; /* specifies the start position for the sticky behavior - 0 is pretty common */_x000D_
  width: 100%;_x000D_
  padding: 5px 0 5px 15px;_x000D_
  color: white;_x000D_
  background-color: #337AB7;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
h1 {_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
div.big {_x000D_
  width: 100%;_x000D_
  min-height: 150vh;_x000D_
  background-color: #1ABB9C;_x000D_
  padding: 10px;_x000D_
}

<body>_x000D_
<header><h1>Testquest</h1></header>_x000D_
<div class="big">Just something big enough to scroll on</div>_x000D_
</body>

The overall dimensions of a range are in its Width and Height properties.

Dim r As Range
Set r = ActiveSheet.Range("A4:H12")

Debug.Print r.Width
Debug.Print r.Height

If you are in ES6 just use the "static" keyword on your method from your example would be the following: static alertMessage: function() { ...
},

Hope can help anyone out there :)

Whilst the listed answer is correct, may I suggest that if your column is to hold case sensitive strings you read the documentation and alter your table definition accordingly.

In my case this amounted to defining my column as:

`tag` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT ''

This is in my opinion preferential to adjusting your queries.

The solution is to set the default value in your .elem. But this annimation work fine with -moz but not yet implement in -webkit

Look at the fiddle I updated from yours : http://jsfiddle.net/DoubleYo/4Vz63/1648/

It works fine with Firefox but not with Chrome

.elem{_x000D_
    position: absolute;_x000D_
    top: 40px;_x000D_

The culprit might lie in the fact that Global.asax has been placed in the wrong directory inside the mvc project. In my case it was placed under /Views but I had to move it should have been placed under the root folder of the project.

In your case you might be the exact opposite - run some tests and see for yourself.

in linux/ubuntu you can do, run following commands

cd ~/.config/JetBrains/PyCharm2020.1
rm eval/PyCharm201.evaluation.key
sed -i '/evlsprt/d' options/other.xml
cd ~/.java/.userPrefs/jetbrains

You asked WHY, not how to cheat it:

Usually because of laziness of programmers of the initial implementation, because they HAVE already put way more effort in other features, delivering more odd side-effects like floats, because they were more requested by designers back then and yet they haven't taken the time to allow this so we can use the FOUR properties to push/pull an element against its neighbors (now we only have four to push, and only 2 to pull).

When html was designed, magazines loved text reflown around images back then, now hated because today we have touch trends, and love squary things with lots of space and nothing to read. That's why they put more pressure on floats than on centering, or they could have designed something like margin-top: fill; or margin: average 0; to simply align the content to the bottom, or distribute its extra space around.

In this case I think it hasn't been implemented because of the same reason that makes CSS to lack of a :parent pseudo-selector: To prevent looping evaluations.

Without being an engineer, I can see that CSS right now is made to paint elements once, remember some properties for future elements to be painted, but NEVER going back to already-painted elements.

That's why (I guess) padding is calculated on the width, because that's the value that was available at the time of starting to paint it.

If you had a negative value for padding, it would affect the outer limits, which has ALREADY been defined when the margin has already been set. I know, nothing has been painted yet, but when you read how the painting process goes, created by geniuses with 90's technology, I feel like I am asking dumb questions and just say "thanks" hehe.

One of the requirements of web pages is that they are quickly available, unlike an app that can take its time and eat the computer resources to get everything correct before displaying it, web pages need to use little resources (so they are fit in every device possible) and be scrolled in a breeze.

If you see applications with complex reflowing and positioning, like InDesign, you can't scroll that fast! It takes a big effort both from processors and graphic card to jump to next pages!

So painting and calculating forward and forgetting about an element once drawn, for now it seems to be a MUST.

I have the same issue with windows10, apache 2.2.25, php 5.2 Im trying to add GD to a working PHP.

how I turn around and change between forward and backward slash, plus trailing or not, I get some variant of ;

PHP Warning: PHP Startup: Unable to load dynamic library 'C:/php\php_gd2.dll' - Det g\xe5r inte att hitta den angivna modulen.\r\n in Unknown on line 0

(swedish translated: 'It is not possible to find the module' )

in this perticular case, the php.ini was: extension_dir = "C:/php"

the dll is put in two places C:\php and C:\php\ext

IS it possible that there is and "error" in the error log entry ? I.e. that the .dll IS found (as a file) but not of the right format, or something like that ??

I think you mean to put the rolling of the random a,b,c, etc within the loop:

a = None # initialise
while not (a in winning_numbers):
    # keep rolling an a until you get one not in winning_numbers
    a = random.randint(1,30)
    winning_numbers.append(a)

Otherwise, a will be generated just once, and if it is in winning_numbers already, it won't be added. Since the generation of a is outside the while (in your code), if a is already in winning_numbers then too bad, it won't be re-rolled, and you'll have one less winning number.

That could be what causes your error in if guess[i] == winning_numbers[i]. (Your winning_numbers isn't always of length 5).

This did the trick for me: (solution from the msdn forum)

goto Controlpanel --> Administrative tools-->Component Services -->computers --> myComputer -->DCOM Config --> Microsoft Excel Application.

right click to get properties dialog. Goto Security tab and customize permissions accordingly.

In Launch and Application Permissions, select Customize, Edit. Add the user / group that calls the application.

Besides the redundant ) this expression will always be true because currentStatus will always match one of these two conditions:

currentStatus !== 'open' || currentStatus !== 'reopen'

perhaps you mean one of

!(currentStatus === 'open' || currentStatus === 'reopen')
(currentStatus !== 'open' && currentStatus !== 'reopen')

try:

ps aux | grep java

and see how you get on

I am surprised no one has mentioned xmlsh. The mission statement :

A command line shell for XML Based on the philosophy and design of the Unix Shells

xmlsh provides a familiar scripting environment, but specifically tailored for scripting xml processes.

A list of shell like commands are provided here.

I use the xed command a lot which is equivalent to sed for XML, and allows XPath based search and replaces.

The sqlite3 .import command won't work for ordinary csv data because it treats any comma as a delimiter even in a quoted string.

This includes trying to re-import a csv file that was created by the shell:

Create table T (F1 integer, F2 varchar);
Insert into T values (1, 'Hey!');
Insert into T values (2, 'Hey, You!');

.mode csv
.output test.csv
select * from T;

Contents of test.csv:
1,Hey!
2,"Hey, You!"

delete from T;

.import test.csv T
Error: test.csv line 2: expected 2 columns of data but found 3

It seems we must transform the csv into a list of Insert statements, or perhaps a different delimiter will work.

Over at SuperUser I saw a suggestion to use LogParser to deal with csv files, I'm going to look into that.

Some minor improvements

->previous answers weren't showing all results

->possible to filter on column name by setting the column name variable

DECLARE @columnname nvarchar(150)
SET @columnname=''

DECLARE @SQL varchar(max)

SELECT @SQL=@SQL+'UNION
select 
'''+d.name+'.''+sh.name+''.''+o.name COLLATE SQL_Latin1_General_CP1_CI_AS as name,c.name COLLATE SQL_Latin1_General_CP1_CI_AS as columnname,c.column_id

Prior to standardization there was ioctl(...FIONBIO...) and fcntl(...O_NDELAY...), but these behaved inconsistently between systems, and even within the same system. For example, it was common for FIONBIO to work on sockets and O_NDELAY to work on ttys, with a lot of inconsistency for things like pipes, fifos, and devices. And if you didn't know what kind of file descriptor you had, you'd have to set both to be sure. But in addition, a non-blocking read with no data available was also indicated inconsistently; depending on the OS and the type of file descriptor the read may return 0, or -1 with errno EAGAIN, or -1 with errno EWOULDBLOCK. Even today, setting FIONBIO or O_NDELAY on Solaris causes a read with no data to return 0 on a tty or pipe, or -1 with errno EAGAIN on a socket. However 0 is ambiguous since it is also returned for EOF.

POSIX addressed this with the introduction of O_NONBLOCK, which has standardized behavior across different systems and file descriptor types. Because existing systems usually want to avoid any changes to behavior which might break backward compatibility, POSIX defined a new flag rather than mandating specific behavior for one of the others. Some systems like Linux treat all 3 the same, and also define EAGAIN and EWOULDBLOCK to the same value, but systems wishing to maintain some other legacy behavior for backward compatibility can do so when the older mechanisms are used.

New programs should use fcntl(...O_NONBLOCK...), as standardized by POSIX.

You can do it using Primefaces like this :

<p:button 
      outcome="/page2.xhtml?faces-redirect=true&amp;id=#{myBean.id}">
</p:button>

Content of script.r:

#!/usr/bin/env Rscript

args = commandArgs(trailingOnly = TRUE)
message(sprintf("Hello %s", args[1L]))

The first line is the shebang line. It’s best practice to use /usr/bin/env Rscript instead of hard-coding the path to your R installation. Otherwise you risk your script breaking on other computers.

Next, make it executable (on the command line):

chmod +x script.r

Invocation from command line:

./script.r world
# Hello world

I had this issue, and solved. This was due to the WHERE clause contains String value instead of integer value.

Use wine - it has IE6 with Gecko support built into it. More information here.

Most answers suggest this is because of different platforms, but there is more to it. From the documentation of object.__hash__(self):

By default, the __hash__() values of str, bytes and datetime objects are “salted” with an unpredictable random value. Although they remain constant within an individual Python process, they are not predictable between repeated invocations of Python.

This is intended to provide protection against a denial-of-service caused by carefully-chosen inputs that exploit the worst case performance of a dict insertion, O(n²) complexity. See http://www.ocert.org/advisories/ocert-2011-003.html for details.

Changing hash values affects the iteration order of dicts, sets and other mappings. Python has never made guarantees about this ordering (and it typically varies between 32-bit and 64-bit builds).

Even running on the same machine will yield varying results across invocations:

$ python -c "print(hash('http://stackoverflow.com'))"
-3455286212422042986
$ python -c "print(hash('http://stackoverflow.com'))"
-6940441840934557333

While:

$ python -c "print(hash((1,2,3)))"
2528502973977326415
$ python -c "print(hash((1,2,3)))"
2528502973977326415

See also the environment variable PYTHONHASHSEED:

If this variable is not set or set to random, a random value is used to seed the hashes of str, bytes and datetime objects.

If PYTHONHASHSEED is set to an integer value, it is used as a fixed seed for generating the hash() of the types covered by the hash randomization.

Its purpose is to allow repeatable hashing, such as for selftests for the interpreter itself, or to allow a cluster of python processes to share hash values.

The integer must be a decimal number in the range [0, 4294967295]. Specifying the value 0 will disable hash randomization.

For example:

$ export PYTHONHASHSEED=0                            
$ python -c "print(hash('http://stackoverflow.com'))"
-5843046192888932305
$ python -c "print(hash('http://stackoverflow.com'))"
-5843046192888932305

You can do this alike here but with your package. In my case, it was lsb_release

I got tired of manually checking for plugin updates so created a tool to do it for me: https://github.com/dpa99c/cordova-check-plugins

Install it globally:

$ npm install -g cordova-check-plugins

Then run from the root of your Cordova project. You can optionally update outdated plugins interactively or automatically, e.g.

$ cordova-check-plugins --update=auto

You seem to just have begun using mysql.

Simple answer: for now use

mysql -u root -p password

Password is usually root by default. You may use other usernames if you have created other user using create user in mysql. For details use "help, help manage accounts, help create users" etc. If you dont want your password to be shown in open just press return key after "-p" and you will be prompted for password next. Hope this resolves the issue.

Different web stacks do support different lengths of http-requests. I know from experience that the early stacks of Safari only supported 4000 characters and thus had difficulty handling ASP.net pages because of the USER-STATE. This is even for POST, so you would have to check the browser and see what the stack limit is. I think that you may reach a limit even on newer browsers. I cannot remember but one of them (IE6, I think) had a limit of 16-bit limit, 32,768 or something.

Using python 3 and opencv-python version 4.4.0, the following code should work:

img_src = cv2.imread('image.png')
img_clone = img_src.copy()

It's possible that you're not fetching the Joined Set. Be sure to include the set in your HQL:

public List<Node> getAll() {
    Session session = sessionFactory.getCurrentSession();
    Query query = session.createQuery("FROM Node as n LEFT JOIN FETCH n.nodeValues LEFT JOIN FETCH n.nodeStats");
    return  query.list();
}

Where your class has 2 sets like:

public class Node implements Serializable {

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeValue> nodeValues;

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeStat> nodeStats;

}

Fiddler2 -> Rules -> Custom Rules

then find function OnBeforeRequest on put in the next script at the end:

if (oSession.HostnameIs("mysite.com")){
    oSession.host="localhost:39901";
}

In addition to the other answers so far, here is unobvious example where static_cast is not sufficient so that reinterpret_cast is needed. Suppose there is a function which in an output parameter returns pointers to objects of different classes (which do not share a common base class). A real example of such function is CoCreateInstance() (see the last parameter, which is in fact void**). Suppose you request particular class of object from this function, so you know in advance the type for the pointer (which you often do for COM objects). In this case you cannot cast pointer to your pointer into void** with static_cast: you need reinterpret_cast<void**>(&yourPointer).

In code:

#include <windows.h>
#include <netfw.h>
.....
INetFwPolicy2* pNetFwPolicy2 = nullptr;
HRESULT hr = CoCreateInstance(__uuidof(NetFwPolicy2), nullptr,
    CLSCTX_INPROC_SERVER, __uuidof(INetFwPolicy2),
    //static_cast<void**>(&pNetFwPolicy2) would give a compile error
    reinterpret_cast<void**>(&pNetFwPolicy2) );

However, static_cast works for simple pointers (not pointers to pointers), so the above code can be rewritten to avoid reinterpret_cast (at a price of an extra variable) in the following way:

#include <windows.h>
#include <netfw.h>
.....
INetFwPolicy2* pNetFwPolicy2 = nullptr;
void* tmp = nullptr;
HRESULT hr = CoCreateInstance(__uuidof(NetFwPolicy2), nullptr,
    CLSCTX_INPROC_SERVER, __uuidof(INetFwPolicy2),
    &tmp );
pNetFwPolicy2 = static_cast<INetFwPolicy2*>(tmp);

You can get the Class reference of any class during run time through the Java Reflection Concept.

Check the Below Code. Explanation is given below

Here is one example that uses returned Class to create an instance of AClass:

package com.xyzws;
class AClass {
    public AClass() {
        System.out.println("AClass's Constructor"); 
    }  
    static {   
        System.out.println("static block in AClass");  
    }
}
public class Program {   
    public static void main(String[] args) {
        try {       
            System.out.println("The first time calls forName:");   
            Class c = Class.forName("com.xyzws.AClass");      
            AClass a = (AClass)c.newInstance();    
            System.out.println("The second time calls forName:");  
            Class c1 = Class.forName("com.xyzws.AClass"); 
        } catch (ClassNotFoundException e) { 
            // ...
        } catch (InstantiationException e) {  
            // ...
        } catch (IllegalAccessException e) { 
            // ...
        }     
    }
}

The printed output is

    The first time calls forName:
    static block in AClass
    AClass's Constructor
    The second time calls forName:

The class has already been loaded so there is no second "static block in AClass"

The Explanation is below

Class.ForName is called to get a Class Object

By Using the Class Object we are creating the new instance of the Class.

Any doubts about this let me know

The compiler can't figure out what type to make the Dictionary, because it's not homogenous. You have values of different types. The only way to get around this is to make it a [String: Any], which will make everything clunky as all hell.

return [
    "title": title,
    "is_draft": isDraft,
    "difficulty": difficulty,
    "duration": duration,
    "cost": cost,
    "user_id": userId,
    "description": description,
    "to_sell": toSell,
    "images": [imageParameters, imageToDeleteParameters].flatMap { $0 }
] as [String: Any]

This is a job for a struct. It'll vastly simplify working with this data structure.

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

You need to use lookahead as some of the other responders have said, but the lookahead has to account for other characters between its target word and the current match position. For example:

(?=.*word1)(?=.*word2)(?=.*word3)

The .* in the first lookahead lets it match however many characters it needs to before it gets to "word1". Then the match position is reset and the second lookahead seeks out "word2". Reset again, and the final part matches "word3"; since it's the last word you're checking for, it isn't necessary that it be in a lookahead, but it doesn't hurt.

In order to match a whole paragraph, you need to anchor the regex at both ends and add a final .* to consume the remaining characters. Using Perl-style notation, that would be:

/^(?=.*word1)(?=.*word2)(?=.*word3).*$/m

The 'm' modifier is for multline mode; it lets the ^ and $ match at paragraph boundaries ("line boundaries" in regex-speak). It's essential in this case that you not use the 's' modifier, which lets the dot metacharacter match newlines as well as all other characters.

Finally, you want to make sure you're matching whole words and not just fragments of longer words, so you need to add word boundaries:

/^(?=.*\bword1\b)(?=.*\bword2\b)(?=.*\bword3\b).*$/m

I made a mix of the answers here, took the code of @Julian and ideas from the others, seems clearer to me, this is what's left:

fiddle http://jsfiddle.net/wq2Ej/

jquery

//store the element
var $cache = $('.my-sticky-element');

//store the initial position of the element
var vTop = $cache.offset().top - parseFloat($cache.css('marginTop').replace(/auto/, 0));
  $(window).scroll(function (event) {
    // what the y position of the scroll is
    var y = $(this).scrollTop();

    // whether that's below the form
    if (y >= vTop) {
      // if so, ad the fixed class
      $cache.addClass('stuck');
    } else {
      // otherwise remove it
      $cache.removeClass('stuck');
    }
  });

css:

.my-sticky-element.stuck {
    position:fixed;
    top:0;
    box-shadow:0 2px 4px rgba(0, 0, 0, .3);
}

1st: the pound symbol is a "special" char in utf8 encoding (try saving £$ in a iso-8859-1 (or iso-8859-15) file and you will get ä when encoding using header)

2nd: change your encoding to utf8 form the file. there are plenty of methods to do it. notepad and notepad++ are great sugestions.

3rd: use ob_start(); (in php) BEFORE YOU MAKE ANY OUTPUT if you are getting weird encoding errors, like missing the encoding sometimes. and YES, this solves it! this kind of errors occurs when a page is encoded in windows-1252(ANSI),ASCII,iso-8859-1(5) and then you have all the others in utf8. this is a terrible error and can cause weird things like session_start(); not working.

4th: other php solutions:

utf8_encode('£');
htmlentities('£');
echo '£';

5th: javascript solutions:

document.getElementById('id_goes_here').innerText.replace('£','£');
document.getElementById('id_goes_here').innerText.replace('£',"\u00A3");
$(this).html().replace('£','£'); //jquery
$(this).html().replace('£',"\u00A3"); //jquery
String.fromCharCode('163');

you MUST send £, so it will repair the broken encoded code point. please, avoid these solutions! use php! these solutions only show how to 'fix' the error, and the last one only to create the well-encoded char.

the easy way use this in button :

 var table = $('#example1').DataTable();
 table.row($(`#yesmediasec-${id}`).closest('tr')).remove( ).draw();

example1 = id table . yesmediasec = id of the button in the row

use it and every thing will be ok

You had it nearly right in the last line. You want

str(bytes_string, 'utf-8')

because the type of bytes_string is bytes, the same as the type of b'abc'.

Try as follows:

public function funcname($id)
{
    $this->db->select('*');
    $this->db->from('Album a'); 
    $this->db->join('Category b', 'b.cat_id=a.cat_id', 'left');
    $this->db->join('Soundtrack c', 'c.album_id=a.album_id', 'left');
    $this->db->where('c.album_id',$id);
    $this->db->order_by('c.track_title','asc');         
    $query = $this->db->get(); 
    return $query->result_array();
}

If no result found CI returns false otherwise true

Let's say you'd like to have an array of instances of Parent class, and a set of child classes Child1, Child2, Child3 extending Parent. There're situations when you're only interested with the parent class implementation, which is more general, and do not care about more specific stuff introduced by child classes.

You should form the command with the contents of the textboxes:

sql = "insert into Main (Firt Name, Last Name) values(" + textbox2.Text + "," + textbox3.Text+ ")";

This, of course, provided that you manage to open the connection correctly.

It would be helpful to know what's happening with your current code. If you are getting some error displayed in that message box, it would be great to know what it's saying.

You should also validate the inputs before actually running the command (i.e. make sure they don't contain malicious code...).

Hey, I have used the same software on an AMD 3Ghz chip, dual core. had 2gbs of ram at the time, and i noticed the emulator ran at an alright speed, but took a ridiculous amount of time to load. I have not done enough development on Android to tell you if this is a common, or even still existing problem, but it is certainly something I remember from my experience.

How to add 1 year to a date and then subtract 1 day from it in asp.net c#

Convert.ToDateTime(txtDate.Value.Trim()).AddYears(1).AddDays(-1);

your sql Statement creating code may be like

statement = connection.createStatement();

To solve "com.microsoft.sqlserver.jdbc.SQLServerException: The requested operation is not supported on forward only result sets" exception change above code with

statement = connection.createStatement(
    ResultSet.TYPE_SCROLL_INSENSITIVE, 
    ResultSet.CONCUR_READ_ONLY);

After above change you can use

int size = 0;
try {
    resultSet.last();
    size = resultSet.getRow();
    resultSet.beforeFirst();
}
catch(Exception ex) {
    return 0;
}
return size;

/**
 * @description determine if an array contains one or more items from another array.
 * @param {array} haystack the array to search.
 * @param {array} arr the array providing items to check for in the haystack.
 * @return {boolean} true|false if haystack contains at least one item from arr.
 */
var findOne = function (haystack, arr) {
    return arr.some(function (v) {
        return haystack.indexOf(v) >= 0;
    });
};

As noted by @loganfsmyth you can shorten it in ES2016 to

/**
 * @description determine if an array contains one or more items from another array.
 * @param {array} haystack the array to search.
 * @param {array} arr the array providing items to check for in the haystack.
 * @return {boolean} true|false if haystack contains at least one item from arr.
 */
var findOne = (haystack, arr) => {
    return arr.some(v => haystack.includes(v));
};

or simply as arr.some(v => haystack.includes(v));

I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.

You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.

Here is my solution:

<div class="form-group row">
  <div class="col-xs-8">
    <label class="control-label">My Label</label>
    <div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
      <input class="form-control" type="text" readonly="" value="12-02-2012">
      <span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
    </div>
  </div>
</div>

CSS changes in datepicker.css on lines 176-177:

.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {

Javascript change in datepicker-bootstrap.js on line 34:

this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;

UPDATE

Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:

CSS changes in datepicker.css on lines 446-447:

.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {

Javascript change in datepicker-bootstrap.js on line 46:

 this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;

Finally, the JavaScript to enable the datepicker (with some options):

 $(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });

Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.

If you are using Rails, there is a squish method

"\tgoodbye\r\n".squish => "goodbye"

"\tgood \t\r\nbye\r\n".squish => "good bye"

These are several ways to apply style to an element. Try any one of the examples below:

1. document.getElementById('div_register').className = 'wide';
  /* CSS */ .wide{width:500px;}
2. document.getElementById('div_register').setAttribute('class','wide');
3. document.getElementById('div_register').style.width = '500px';

I had the same issue. Combining various approaches from the internet (and above) come up with the following approach (checkEmails.py)

class CheckMailer:

        def __init__(self, filename="LOG1.txt", mailbox="Mailbox - Another User Mailbox", folderindex=3):
            self.f = FileWriter(filename)
            self.outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI").Folders(mailbox)
            self.inbox = self.outlook.Folders(folderindex)


        def check(self):                
        #===============================================================================
        # for i in xrange(1,100):                           #Uncomment this section if index 3 does not work for you
        #     try:
        #         self.inbox = self.outlook.Folders(i)     # "6" refers to the index of inbox for Default User Mailbox
        #         print "%i %s" % (i,self.inbox)            # "3" refers to the index of inbox for Another user's mailbox
        #     except:
        #         print "%i does not work"%i
        #===============================================================================

                self.f.pl(time.strftime("%H:%M:%S"))
                tot = 0                
                messages = self.inbox.Items
                message = messages.GetFirst()
                while message:
                    self.f.pl (message.Subject)
                    message = messages.GetNext()
                    tot += 1
                self.f.pl("Total Messages found: %i" % tot)
                self.f.pl("-" * 80)
                self.f.flush()

if __name__ == "__main__":
    mail = CheckMailer()
    for i in xrange(320):  # this is 10.6 hours approximately
            mail.check()
            time.sleep(120.00)

For concistency I include also the code for the FileWriter class (found in FileWrapper.py). I needed this because trying to pipe UTF8 to a file in windows did not work.

class FileWriter(object):
    '''
    convenient file wrapper for writing to files
    '''


    def __init__(self, filename):
        '''
        Constructor
        '''
        self.file = open(filename, "w")

    def pl(self, a_string):
        str_uni = a_string.encode('utf-8')
        self.file.write(str_uni)
        self.file.write("\n")

    def flush(self):
        self.file.flush()

CREATE PROCEDURE sp_deleteUserDetails
    @Email varchar(255)
AS
    declare @tempRegId as int
    Delete UserRegistration where Email=@Email  
    set @tempRegId = (select Id from UserRegistration where Email = @Email)
    Delete UserProfile where RegID=@tempRegId

RETURN 0

In case you want to work with the original MNIST files, here is how you can deserialize them.

If you haven't downloaded the files yet, do that first by running the following in the terminal:

wget http://yann.lecun.com/exdb/mnist/train-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/train-labels-idx1-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-labels-idx1-ubyte.gz

Then save the following as deserialize.py and run it.

import numpy as np
import gzip

IMG_DIM = 28

def decode_image_file(fname):
    result = []
    n_bytes_per_img = IMG_DIM*IMG_DIM

    with gzip.open(fname, 'rb') as f:
        bytes_ = f.read()
        data = bytes_[16:]

        if len(data) % n_bytes_per_img != 0:
            raise Exception('Something wrong with the file')

        result = np.frombuffer(data, dtype=np.uint8).reshape(
            len(bytes_)//n_bytes_per_img, n_bytes_per_img)

    return result

def decode_label_file(fname):
    result = []

    with gzip.open(fname, 'rb') as f:
        bytes_ = f.read()
        data = bytes_[8:]

        result = np.frombuffer(data, dtype=np.uint8)

    return result

train_images = decode_image_file('train-images-idx3-ubyte.gz')
train_labels = decode_label_file('train-labels-idx1-ubyte.gz')

test_images = decode_image_file('t10k-images-idx3-ubyte.gz')
test_labels = decode_label_file('t10k-labels-idx1-ubyte.gz')

The script doesn't normalize the pixel values like in the pickled file. To do that, all you have to do is

train_images = train_images/255
test_images = test_images/255

If you are using text-overflow:ellipsis, the browser will show the contents whatever possible within that container. But if you want to specifiy the number of letters before the dots or strip some contents and add dots, you can use the below function.

function add3Dots(string, limit)
{
  var dots = "...";
  if(string.length > limit)
  {
    // you can also use substr instead of substring
    string = string.substring(0,limit) + dots;
  }
 
    return string;
}

call like

add3Dots("Hello World",9);

outputs

Hello Wor...

See it in action here

function add3Dots(string, limit)
{
  var dots = "...";
  if(string.length > limit)
  {
    // you can also use substr instead of substring
    string = string.substring(0,limit) + dots;
  }

    return string;
}



console.log(add3Dots("Hello, how are you doing today?", 10));

I had a same issue .I removed the extension from the file name.Example my file name was saved as xyz. csv. i saved it as xyz.

Keep it simple:

import os
relevant_path = "[path to folder]"
included_extensions = ['jpg','jpeg', 'bmp', 'png', 'gif']
file_names = [fn for fn in os.listdir(relevant_path)
              if any(fn.endswith(ext) for ext in included_extensions)]

I prefer this form of list comprehensions because it reads well in English.

I read the fourth line as: For each fn in os.listdir for my path, give me only the ones that match any one of my included extensions.

It may be hard for novice python programmers to really get used to using list comprehensions for filtering, and it can have some memory overhead for very large data sets, but for listing a directory and other simple string filtering tasks, list comprehensions lead to more clean documentable code.

The only thing about this design is that it doesn't protect you against making the mistake of passing a string instead of a list. For example if you accidentally convert a string to a list and end up checking against all the characters of a string, you could end up getting a slew of false positives.

But it's better to have a problem that's easy to fix than a solution that's hard to understand.

jQuery also doesn't allow you to call their latest file over SSL, a consideration if you want to use jQuery in a shopping cart etc.

e.g.

<script type="text/javascript" src="https://code.jquery.com/jquery-latest.min.js"></script>

will give you a security error.

Google's API will let you call over SSL:

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
  google.load("jquery", "1.7");
</script>

@Flubba, does this allow me to have folders inside my include directory? flat include directories give me nightmares. as the whole objects directory should be in the inc directory.

Oh yes, absolutely. So for example, we use a single layer of subfolders, generally:

require_once('library/string.class.php')

You need to be careful with relying on the include path too much in really high traffic sites, because php has to hunt through the current directory and then all the directories on the include path in order to see if your file is there and this can slow things up if you're getting hammered.

So for example if you're doing MVC, you'd put the path to your application directoy in the include path and then specify refer to things in the form

'model/user.class'
'controllers/front.php'

or whatever.

But generally speaking, it just lets you work with really short paths in your PHP that will work from anywhere and it's a lot easier to read than all that realpath document root malarkey.

The benefit of those script-based alternatives others have suggested is they work anywhere, even on shared boxes; setting the include path requires a little more thought and effort but as I mentioned lets you start using __autoload which just the coolest.

Have you tried changing the specific levels of your Hospital vector?

levels(survey$hospital)[levels(survey$hospital) == "Hospital #1"] <- "Hosp 1"
levels(survey$hospital)[levels(survey$hospital) == "Hospital #2"] <- "Hosp 2"
levels(survey$hospital)[levels(survey$hospital) == "Hospital #3"] <- "Hosp 3"

Use a table inside a div.

<div>
   <table style='margin-left: auto; margin-right: auto'>
        <tr>
           <td>
              <div>Your content </div>
           </td>
           <td>
              <div>Your content </div>
           </td>
        </tr>
   </table>
</div>

With modern browsers, you can set the textContent property, see Node.textContent:

var span = document.getElementById("myspan");
span.textContent = "some text";

So generally this has been solved, but you might get this error message because the date you use is not in the correct format.

I know this is an old post, but whenever I run this I get NA all the way down my date column. My dates are in this format 20150521 – NealC Jun 5 '15 at 16:06

If you have dates of this format just check the format of your dates with:

str(sides$date)

If the format is not a character, then convert it:

as.character(sides$date)

For as.Date, you won't need an origin any longer, because this is supplied for numeric values only. Thus you can use (assuming you have the format of NealC):

as.Date(as.character(sides$date),format="%Y%m%d")

I hope this might help some of you.

Add a border to the regular item, the same color as the background, so that it cannot be seen. That way the item has a border: 1px whether it is being hovered or not.

When a client connects to an Oracle server, it first connnects to the Oracle listener service. It often redirects the client to another port. So the client has to open another connection on a different port, which is blocked by the firewall.

So you might in fact have encountered a firewall problem due to Oracle port redirection. It should be possible to diagnose it with a network monitor on the client machine or with the firewall management software on the firewall.

You didn't say which database server you are using, but if temp tables are available they may be the best approach.

// table is a temp table
select ... into #table ....
SELECT COUNT(column1),column1 FROM #table GROUP BY column1  
SELECT COUNT(column2),column2 FROM #table GROUP BY column2  
SELECT COUNT(column3),column3 FROM #table GROUP BY column3  
// drop may not be required
drop table #table

Just leave out the ''

You want:

document.cookie = cookieName +"=" + cookieValue + ";domain=.example.com;path=/;expires=" + myDate;

As per the RFC 2109, to have a cookie available to all subdomains, you must put a . in front of your domain.

Setting the path=/ will have the cookie be available within the entire specified domain(aka .example.com).

So here is the brief summary for Bootstrap 4:

<div class="container-fluid px-0">
  <div class="row no-gutters">
    <div class="col-12">          //any cols you need
        ...
    </div>
  </div>
</div>

It works for me.

after your pc connects to other pc use these 4 step:
4 steps:
1- Edit this file: httpd.conf
for that click on wamp server and select Apache and select httpd.conf
2- Find this text: Deny from all
in the below tag:

  <Directory "c:/wamp/www"><!-- maybe other url-->

    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see

    #
    Options Indexes FollowSymLinks

    #

    #
    # Controls who can get stuff from this server.

     Order Deny,Allow
    Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
</Directory>

3- Change to: Deny from none
like this:

<Directory "c:/wamp/www">

    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:

    #
    # Controls who can get stuff from this server.

     Order Deny,Allow
    Deny from none
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

4- Restart Apache
Don't forget restart Apache or all servises!!!

It doesn't need a installation process.

I have pinned "VSCore" on my taskbar (win10), so open it, and open a task manager choose "Visual Studio Core" process expand left arrow and over any of them child process right button over it and click in "Open File Location" menu.

If you don't remember where is installed search "Code.exe" file in all your hard drives.

I am just throwing in another one for reference since there was an additional question to Mark Edgars input and here is an additional example and touches on the topic overall:

[[ `cmd` ]] && echo success_else_silence

Which is the same as cmd || exit errcode as someone showed.

For example, I want to make sure a partition is unmounted if mounted:

[[ `mount | grep /dev/sda1` ]] && umount /dev/sda1

i got very good results using a user function from http://php.net/manual/de/function.mime-content-type.php @''john dot howard at prismmg dot com 26-Oct-2009 03:43''

function get_mime_type($filename, $mimePath = '../etc') { ...

which doesnt use finfo, exec or deprecated function

works well also with remote ressources!

In the simplest terms, git pull does a git fetch followed by a git merge.

You can do a git fetch at any time to update your remote-tracking branches under refs/remotes/<remote>/.

This operation never changes any of your own local branches under refs/heads, and is safe to do without changing your working copy. I have even heard of people running git fetch periodically in a cron job in the background (although I wouldn't recommend doing this).

A git pull is what you would do to bring a local branch up-to-date with its remote version, while also updating your other remote-tracking branches.

From the Git documentation for git pull:

In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD.

There is not a program but you can make a batch file and run a command like that :

powershell "start-process 'C:\Program Files (x86)\IIS Express\iisexpress.exe' -workingdirectory 'C:\Program Files (x86)\IIS Express\' -windowstyle Hidden"

Use the -ExpandProperty flag of Select-Object

$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority

Update to answer the other question:

Note that you can as well just access the property:

$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

So to get multiple of these into variables:

$var=Get-WSManInstance -enumerate wmicimv2/win32_process
   $prio = $var.Priority
   $pid = $var.ProcessID

I ran into similar issues whose cause and solution turned out both to be rather simple:

Main Cause: Did not import the proper cert using keytool

NOTE: Only import root CA (or your own self-signed) certificates

NOTE: don't import an intermediate, non certificate chain root cert

Solution Example for imap.gmail.com

1. Determine the root CA cert:

   openssl s_client -showcerts -connect imap.gmail.com:993
   

   in this case we find the root CA is Equifax Secure Certificate Authority

2. Download root CA cert.
3. Verify downloaded cert has proper SHA-1 and/or MD5 fingerprints by comparing with info found here

4. Import cert for javax.net.ssl.trustStore:

   keytool -import -alias gmail_imap -file Equifax_Secure_Certificate_Authority.pem
   

5. Run your java code

there is a limited alternative you can use

header:

class std_int_vector;

class A{
    std_int_vector* vector;
public:
    A();
    virtual ~A();
};

cpp:

#include "header.h"
#include <vector>
class std_int_vector: public std::vectror<int> {}

A::A() : vector(new std_int_vector()) {}
[...]

not tested in real programs, so expect it to be non-perfect.

Here what i did, it works fine.

step 1:(it lists docker container with its name)

docker ps -a

step 2:

docker rm name_of_the_docker_container

Please change your project-level build.gradle file in which you have to change your dependencies class path of google-services or build.gradle path.

buildscript {

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

From the documentation:

/is Includes the same files. /it Includes "tweaked" files.

"Same files" means files that are identical (name, size, times, attributes). "Tweaked files" means files that have the same name, size, and times, but different attributes.

robocopy src dst sample.txt /is      # copy if attributes are equal
robocopy src dst sample.txt /it      # copy if attributes differ
robocopy src dst sample.txt /is /it  # copy irrespective of attributes

This answer on Super User has a good explanation of what kind of files the selection parameters match.

With that said, I could reproduce the behavior you describe, but from my understanding of the documentation and the output robocopy generated in my tests I would consider this a bug.

The file is listed as copied, and since it becomes a same file after the first robocopy run at least the times are synced. However, even though seven bytes have been copied according to the output no data was actually written to the destination file in both cases despite the data flag being set (via /copyall). The behavior also doesn't change if the data flag is set explicitly (/copy:d).

I had to modify the last write time to get robocopy to actually synchronize the data.

An admittedly ugly workaround would be to change the last write time of same/tweaked files to force robocopy to copy the data:

& robocopy src dst /is /it /l /ndl /njh /njs /ns /nc |
  Where-Object { $_.Trim() } |
  ForEach-Object {
    $f = Get-Item $_
    $f.LastWriteTime = $f.LastWriteTime.AddSeconds(1)
  }
& robocopy src dst /copyall /mir

Switching to xcopy is probably your best option:

& xcopy src dst /k/r/e/i/s/c/h/f/o/x/y

you can also try this in sql-server !!

select a.city,a.total + b.total as mytotal from [dbo].[cash] a join [dbo].[cheque] b on a.city=b.city 

demo

or try using sum,union

select sum(total)  as mytotal,city
from
(
    select * from cash union
    select * from cheque
) as vij
group by city 

I've had this sort of problem.....

The solve: cmd / powershell run as ADMINISTRATOR! I always forget.

Notice: In powershell, you need to put .\ for example:

.\httpd -k shutdown .\httpd -k stop .\httpd -k uninstall

Result: Removing the apache2.4 service The Apache2.4 service has been removed successfully.

Task are being executed on the ThreadPool (at least, if you are using the default factory), so aborting the thread cannot affect the tasks. For aborting tasks, see Task Cancellation on msdn.

use #0000 (only four zeros otherwise it will be considered as black) this is the color code for transparent. You can use it directly but I recommend you to define a color in color.xml so you can enjoy re-usefullness of the code.

For UnitTest angular 2 with angular material you have to add MatSelectModule module in imports section.

import { MatSelectModule } from '@angular/material';

beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ CreateUserComponent ],
      imports : [ReactiveFormsModule,        
        MatSelectModule,
        MatAutocompleteModule,......

      ],
      providers: [.........]
    })
    .compileComponents();
  }));

You need to set the content-type in postman as JSON (application/json).

Go to the body inside your POST request, there you will find the raw option.

Right next to it, there will be a drop down, select JSON (application.json).

As an unordered collection type, set([8, 1, 6]) is equivalent to set([1, 6, 8]).

While it might be nicer to display the set contents in sorted order, that would make the repr() call more expensive.

Internally, the set type is implemented using a hash table: a hash function is used to separate items into a number of buckets to reduce the number of equality operations needed to check if an item is part of the set.

To produce the repr() output it just outputs the items from each bucket in turn, which is unlikely to be the sorted order.

All the three syntax work very well.

Another way is to first write

path = r'C:\user\...................' (whatever is the path for you)

and then passing it to os.chdir(path)

It is also worth noting that in the cascade, an id (#) selector is more specific than a b (.) selector. Therefore, rules in the id statement will override rules in the class statement.

For example, if both of the following statements:

.headline {
  color:red;
  font-size: 3em;
}

#specials {
  color:blue;
  font-style: italic;
}

are applied to the same HTML element:

<h1 id="specials" class="headline">Today's Specials</h1>

the color:blue rule would override the color:red rule.

Something that is not relevant for the OP, but maybe for someone else in the future:

For pixels (px), if the value is "0", the unit can be omitted: right: 0 and right: 0px both work.

However I noticed that in Firefox and Chrome this is not the case for the seconds unit (s). While transition: right 1s ease 0s works, transition: right 1s ease 0 (missing unit s for last value transition-delay) does not (it does work in Edge however).

In the following example, you'll see that right works for both 0px and 0, but transition only works for 0s and it doesn't work with 0.

Why not use rs.getRow()?

int getRow()
           throws SQLException
Retrieves the current row number. The first row is number 1, the second number 2, and so on.
Note:Support for the getRow method is optional for ResultSets with a result set type of TYPE_FORWARD_ONLY

Returns:
the current row number; 0 if there is no current row
Throws:
SQLException - if a database access error occurs or this method is called on a closed result set
SQLFeatureNotSupportedException - if the JDBC driver does not support this method
Since:
1.2

For me check "if (rs.getRow() != 0)" seems to work just fine.

It is working in macOS Mojave at least.

First, make sure you have Tkinter module installed.

sudo apt-get install python-tk

In python 2 the package name is Tkinter not tkinter.

from Tkinter import *

Export the SELECT result

• After you run a SELECT: Query > Export Results...

  

Export table data

• In the Navigator, right click on the table > Table Data Export Wizard

  

• All columns and rows are included by default, so click on Next.

• Select File Path, type, Field Separator (by default it is ;, not ,!!!) and click on Next.

  

• Click Next > Next > Finish and the file is created in the specified location

simply don't close in

remove in.close() from your code.

To explain the difference between these two let me explain the difference between encodeURI and encodeURIComponent.

The main difference is that:

• The encodeURI function is intended for use on the full URI.
• The encodeURIComponent function is intended to be used on .. well .. URI components that is any part that lies between separators (; / ? : @ & = + $ , #).

So, in encodeURIComponent these separators are encoded also because they are regarded as text and not special characters.

Now back to the difference between the decode functions, each function decodes strings generated by its corresponding encode counterpart taking care of the semantics of the special characters and their handling.

in my webpack.config.js (Version 1,2,3) file, I have

function isExternal(module) {
  var context = module.context;

  if (typeof context !== 'string') {
    return false;
  }

  return context.indexOf('node_modules') !== -1;
}

in my plugins array

plugins: [
  new CommonsChunkPlugin({
    name: 'vendors',
    minChunks: function(module) {
      return isExternal(module);
    }
  }),
  // Other plugins
]

Now I have a file that only adds 3rd party libs to one file as required.

If you want get more granular where you separate your vendors and entry point files:

plugins: [
  new CommonsChunkPlugin({
    name: 'common',
    minChunks: function(module, count) {
      return !isExternal(module) && count >= 2; // adjustable
    }
  }),
  new CommonsChunkPlugin({
    name: 'vendors',
    chunks: ['common'],
    // or if you have an key value object for your entries
    // chunks: Object.keys(entry).concat('common')
    minChunks: function(module) {
      return isExternal(module);
    }
  })
]

Note that the order of the plugins matters a lot.

Also, this is going to change in version 4. When that's official, I update this answer.

Update: indexOf search change for windows users

The following solution does not use inline blocks. However, it requires two helper divs:

1. The content is floated
2. The inner helper is floated (it stretches as much as the content)
3. The inner helper is pushed right 50% (its left aligns with center of outer helper)
4. The content is pulled left 50% (its center aligns with left of inner helper)
5. The outer helper is set to hide the overflow

Since it's now 2015, if you stumbled across this question then you should probably be using window.matchMedia (and, if it's still 2015, polyfilling for older browsers):

if (matchMedia('handheld').matches) {
    //...
} else {
    //...
}

Below snippet execute some code snippet. If you got any error while executing the code snippet, sleep for M milliseconds and retry. Reference link.

public void retryAndExecuteErrorProneCode(int noOfTimesToRetry, CodeSnippet codeSnippet, int sleepTimeInMillis)
  throws InterruptedException {

 int currentExecutionCount = 0;
 boolean codeExecuted = false;

 while (currentExecutionCount < noOfTimesToRetry) {
  try {
   codeSnippet.errorProneCode();
   System.out.println("Code executed successfully!!!!");
   codeExecuted = true;
   break;
  } catch (Exception e) {
   // Retry after 100 milliseconds
   TimeUnit.MILLISECONDS.sleep(sleepTimeInMillis);
   System.out.println(e.getMessage());
  } finally {
   currentExecutionCount++;
  }
 }

 if (!codeExecuted)
  throw new RuntimeException("Can't execute the code within given retries : " + noOfTimesToRetry);
}

The JS answer to this question is:

http://jsfiddle.net/6WAnd/20/

or something similar

The solution I have found is to use $parse.

"Converts Angular expression into a function."

If anyone has a better one please add a new answer to the question!

Here is the example:

var the_string = 'life.meaning';

// Get the model
var model = $parse(the_string);

// Assigns a value to it
model.assign($scope, 42);

// Apply it to the scope
// $scope.$apply(); <- According to comments, this is no longer needed

console.log($scope.life.meaning);  // logs 42

Try also the pytracemalloc project which provides the memory usage per Python line number.

EDIT (2014/04): It now has a Qt GUI to analyze snapshots.

Use GetParent() as shown, works nicely. Add error checking as you need.

var fn = openFileDialogSapTable.FileName;
var currentPath = Path.GetFullPath( fn );
currentPath = Directory.GetParent(currentPath).FullName;

For Xamarin Developers, you can use:

intent.SetFlags(ActivityFlags.NewTask | ActivityFlags.ClearTask);

I would suggest better cek first if the current page has a hash. Otherwise it will be undefined.

$(window).on('load', function(){        
    if( location.hash && location.hash.length ) {
       var hash = decodeURIComponent(location.hash.substr(1));
       $('ul'+hash+':first').show();;
    }       
});

I had the same trouble, this is what worked for me.

You can click at the wampserver icon, then at the PHP error log. Check if it says this: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_ldap.dll'

If yes, then you can reload your version of PHP, by clicking at the wampserver icon, then PHP, then version, and then you click at your version. Wait for everything to be online again, then try to access phpmyadmin.

If you install newer versions of ionic globally you can run ionic cordova resources and it will generate all of the splashscreen images for you along with the correct sizes.

GlobalStrings.AddRange(localStrings);

Note: You cannot declare the list object using the interface (IList).
Documentation: List<T>.AddRange(IEnumerable<T>).

Form validation is very much straight forward in Angular 2

Here is an example,

<form (ngSubmit)="onSubmit()" #myForm="ngForm">

 <div class="form-group">
  <label for="firstname">First Name</label>
  <input type="text" class="form-control" id="firstname" 
   required [(ngModel)]="firstname" name="firstname">
 </div>

 <div class="form-group">
  <label for="middlename">Middle Name</label>
  <input type="text"  class="form-control" id="middlename" 
   [(ngModel)]="middlename" name="middlename">
 </div>

 <div class="form-group">
  <label for="lastname">Last Name</label>
  <input type="text"  class="form-control" id="lastname" 
   required minlength = '2' maxlength="6" [(ngModel)] = "lastname" name="lastname">
 </div>

 <div class="form-group">
  <label for="mobnumber">Mob Number</label>
  <input type="text"  class="form-control" id="mobnumber"  
   minlength = '2' maxlength="10" pattern="^[0-9()\-+\s]+$" 
   [(ngModel)] = "mobnumber" name="mobnumber">
 </div>

 <button type="submit" [disabled]="!myForm.form.valid">Submit</button>

</form>

You need something like this, maybe it can be improved. This is a first attempt:

...
import org.springframework.core.env.PropertySource;
import org.springframework.core.env.AbstractEnvironment;
import org.springframework.core.env.Environment;
import org.springframework.core.env.MapPropertySource;
...

@Configuration
...
@org.springframework.context.annotation.PropertySource("classpath:/config/default.properties")
...
public class GeneralApplicationConfiguration implements WebApplicationInitializer 
{
    @Autowired
    Environment env;

    public void someMethod() {
        ...
        Map<String, Object> map = new HashMap();
        for(Iterator it = ((AbstractEnvironment) env).getPropertySources().iterator(); it.hasNext(); ) {
            PropertySource propertySource = (PropertySource) it.next();
            if (propertySource instanceof MapPropertySource) {
                map.putAll(((MapPropertySource) propertySource).getSource());
            }
        }
        ...
    }
...

Basically, everything from the Environment that's a MapPropertySource (and there are quite a lot of implementations) can be accessed as a Map of properties.

You never refer to a specific style sheet. All CSS rules in a document are internally fused into one.

In the case of rules in both style sheets that apply to the same element with the same specificity, the style sheet embedded later will override the earlier one.

You can use an element inspector like Firebug to see which rules apply, and which ones are overridden by others.

That task should be done by the next layer up in your software stack. SQL is a data repository, not a presentation system

You can do it with

CONVERT(VARCHAR(10), fmdate(), 101)

But you shouldn't

just use this,

utf8_encode($string);

you've to replace your $arr with $string.

I think it will work...try this.

Here's a very simple python function to compute R^2 from the actual and predicted values assuming y and y_hat are pandas series:

def r_squared(y, y_hat):
    y_bar = y.mean()
    ss_tot = ((y-y_bar)**2).sum()
    ss_res = ((y-y_hat)**2).sum()
    return 1 - (ss_res/ss_tot)

Although @airdrumz solutions works, you will get lots of errors about you doing it wrong by accessing ID directly, this is not good for future compatibility.

But it lead me to inspect the object and create this OOP approach:

function myplug_get_prod_attrs() {
    // Enqueue scripts happens very early, global $product has not been created yet, neither has the post/loop
    global $product;
    $wc_attr_objs = $product->get_attributes();
    $prod_attrs = [];
    foreach ($wc_attr_objs as $wc_attr => $wc_term_objs) {
        $prod_attrs[$wc_attr] = [];
        $wc_terms = $wc_term_objs->get_terms();
        foreach ($wc_terms as $wc_term) {
            array_push($prod_attrs[$wc_attr], $wc_term->slug);
        }
    }
    return $prod_attrs;
}

Bonus, if you are performing the above early before the global $product item is created (e.g. during enqueue scripts), you can make it yourself with:

    $product = wc_get_product(get_queried_object_id());

There is a much easier way to compile and run C++ code, no configuration needed:

1. Install the Code Runner Extension
2. Open your C++ code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.

Moreover you could update the config in settings.json using different C++ compilers as you want, the default config for C++ is as below:

"code-runner.executorMap": {
    "cpp": "g++ $fullFileName && ./a.out"
}

Let'e me give an example:

1. client connect to server, and send 1MB data to server every 1 second.

2. server side accept a connection, and then sleep 20 second, without recv msg from client.So the tcp send buffer in the client side will be full.

Code in client side:

#include <arpa/inet.h>
#include <sys/socket.h>

    if (r) {                                                                                     \
        printf(__VA_ARGS__);                                                                     \

    exit_if(flags < 0, "fcntl failed");
    int r = fcntl(fd, F_SETFL, flags | O_NONBLOCK);
    exit_if(r < 0, "fcntl failed");
}

void test_full_sock_buf_1(){

    struct sockaddr_in addr;
    memset(&addr, 0, sizeof addr);
    addr.sin_family = AF_INET;
    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;


    int fd = socket(AF_INET, SOCK_STREAM, 0);
    exit_if(fd<0, "create socket error");

    int ret = connect(fd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
    exit_if(ret<0, "connect to server error");
    setNonBlock(fd);

    printf("connect to server success");

    const int LEN = 1024 * 1000;
    char msg[LEN];  // 1MB data
    memset(msg, 'a', LEN);

    for (int i = 0; i < 1000; ++i) {
        int len = send(fd, msg, LEN, 0);
        printf("send: %d, erron: %d, %s \n", len, errno, strerror(errno));
        sleep(1);
    }

}

int main(){
    test_full_sock_buf_1();

    return 0;
}

Code in server side:

    #include <arpa/inet.h>
    #include <sys/socket.h>
    #include <stdio.h>
    #include <errno.h>
    #include <fcntl.h>

    short port = 8000;
    struct sockaddr_in addr;
    memset(&addr, 0, sizeof addr);
    addr.sin_family = AF_INET;
    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;

    int r = ::bind(listenfd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
    exit_if(r<0, "bind socket error");

    r = listen(listenfd, 100);
    exit_if(r<0, "listen socket error");

    socklen_t rsz = sizeof(raddr);
    int cfd = accept(listenfd, (struct sockaddr *) &raddr, &rsz);
    exit_if(cfd<0, "accept socket error");

    sockaddr_in peer;
    socklen_t alen = sizeof(peer);
    getpeername(cfd, (sockaddr *) &peer, &alen);

    printf("accept a connection from %s:%d\n", inet_ntoa(peer.sin_addr), ntohs(peer.sin_port));

    printf("but now I will sleep 15 second, then exit");
    sleep(15);
}

Start server side, then start client side.

server side may output:

accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0

client side may output:

connect to server successsend: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success

send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 

You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer get full, but you still send data, so you may get Resource temporarily unavailable error.

This class-based javascript animation works in AngularJS 1.2 (and 1.4 tested)

Edit: I ended up abandoning this code and went a completely different direction. I like my other answer much better. This answer will give you some problems in certain situations.

myApp.animation('.ng-show-toggle-slidedown', function(){
  return {
    beforeAddClass : function(element, className, done){
        if (className == 'ng-hide'){
            $(element).slideUp({duration: 400}, done);
        } else {done();}
    },
    beforeRemoveClass :  function(element, className, done){
        if (className == 'ng-hide'){
            $(element).css({display:'none'});
            $(element).slideDown({duration: 400}, done);
        } else {done();}
    }
}

});

Simply add the .ng-hide-toggle-slidedown class to the container element, and the jQuery slide down behavior will be implemented based on the ng-hide class.

You must include the $(element).css({display:'none'}) line in the beforeRemoveClass method because jQuery will not execute a slideDown unless the element is in a state of display: none prior to starting the jQuery animation. AngularJS uses the CSS

.ng-hide:not(.ng-hide-animate) {
    display: none !important;
}

to hide the element. jQuery is not aware of this state, and jQuery will need the display:none prior to the first slide down animation.

The AngularJS animation will add the .ng-hide-animate and .ng-animate classes while the animation is occuring.

Update on @ghostJago answer above

for me it worked as the following lines in VS2017

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

You can use Phonegap (Cordova) to develop iOS Apps without a Mac, but yout would still need a Mac to submit your application to the App Store. We developed a cloud application which also can publish your app without a Mac https://www.wenz.io/ApplicationLoader. Currently we are in beta and you can use the service for free.

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

Perhaps this complementary example of "match" would be helpful.

Having two datasets:

first_dataset <- data.frame(name = c("John", "Luke", "Simon", "Gregory", "Mary"),
                            role = c("Audit", "HR", "Accountant", "Mechanic", "Engineer"))

second_dataset <- data.frame(name = c("Mary", "Gregory", "Luke", "Simon"))

If the name column contains only unique across collection values (across whole collection) then you can access row in other dataset by value of index returned by match

name_mapping <- match(second_dataset$name, first_dataset$name)

match returns proper row indexes of names in first_dataset from given names from second: 5 4 2 1 example here - accesing roles from first dataset by row index (by given name value)

for(i in 1:length(name_mapping)) {
    role <- as.character(first_dataset$role[name_mapping[i]])   
    second_dataset$role[i] = role
}

===

second dataset with new column:
     name       role
1    Mary   Engineer
2 Gregory   Mechanic
3    Luke Supervisor
4   Simon Accountant

The easiest solution I have found is this one :

<a href="#" ng-click="do(); $event.preventDefault()">Click</a>

While some suggestions have included tkinter and wxPython, the other part of the answer to your question is that you will also need to package it using something like py2app, pyinstaller, or py2exe (depending on the operating system). You mentioned the other machines do not have python, so this would be required in order to distribute the entire python environment with your app.

Also have a look at PySide or PyQt. They have a ton of tutorials everywhere and heavy documentation from Qt.

There is an Oracle article I found regarding Java 9 module system

By default, a type in a module is not accessible to other modules unless it’s a public type and you export its package. You expose only the packages you want to expose. With Java 9, this also applies to reflection.

As pointed out in https://stackoverflow.com/a/50251958/134894, the differences between the AccessibleObject#setAccessible for JDK8 and JDK9 are instructive. Specifically, JDK9 added

This method may be used by a caller in class C to enable access to a member of declaring class D if any of the following hold:

• C and D are in the same module.
• The member is public and D is public in a package that the module containing D exports to at least the module containing C.
• The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D.
• D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

which highlights the significance of modules and their exports (in Java 9)

Use the instanceof operator:

if(a instanceof MyClass)
{
    //do something
}

plt.gca().xaxis.grid(True) proved to be the solution for me

iOS 8+

func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        tableView.tableHeaderView?.backgroundColor = UIColor.blue()
}

Its a very late answer, but you can also use the Collections.singleton:

List<String> list = new ArrayList<String>(Arrays.asList("", "Hi", null, "How"));
list.removeAll(Collections.singleton(null));
list.removeAll(Collections.singleton(""));

I just wanted to add an additional option: In your input add the form tag and specify the name of a form that doesn't exist on your page:

<input form="fakeForm" type="text" readonly value="random value" />

I tried with this in the context field:

this.getActivity().getParent()

and it works fine for me. This was from a class which extends from "Fragment":

public class filtro extends Fragment{...

No, I don't think you can append key/value pairs. The only thing closest that I am aware of is using the store method:

h = {}
h.store("key", "value")

DECLARE @id INT 
SET @id = 0 
UPDATE cartemp
SET @id = CarmasterID = @id + 1 
GO

You don't need to use anything but plain React and ES6 to achieve what you want. As per Jim's answer, just define the constant in the right place. I like the idea of keeping the constant local to the component if not needed externally. The below is an example of possible usage.

import React from "react";

const sizeToLetterMap = {
  small_square: 's',
  large_square: 'q',
  thumbnail: 't',
  small_240: 'm',
  small_320: 'n',
  medium_640: 'z',
  medium_800: 'c',
  large_1024: 'b',
  large_1600: 'h',
  large_2048: 'k',
  original: 'o'
};

class PhotoComponent extends React.Component {
  constructor(args) {
    super(args);
  }

  photoUrl(image, size_text) {
    return (<span>
      Image: {image}, Size Letter: {sizeToLetterMap[size_text]}
    </span>);
  }

  render() {
    return (
      <div className="photo-wrapper">
        The url is: {this.photoUrl(this.props.image, this.props.size_text)}
      </div>
    )
  }
}

export default PhotoComponent;

// Call this with <PhotoComponent image="abc.png" size_text="thumbnail" />
// Of course the component must first be imported where used, example:
// import PhotoComponent from "./photo_component.jsx";

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

select min(table.id), table.column1
from table 
group by table.column1

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

I also faced this same issue while working in my development environment, the problem was that I left host: localhost commented out in the config/database.yml file.

So my application could not connect to the PostgreSQL database, simply uncommenting it solved the issue.

development:
  <<: *default
  database: database_name

  username: database_username 

  password: database_password

  host: localhost

That's all.

I hope this helps

You may use a delegate to solve this issue. Here is an example that is showing how to update a textBox using diffrent thread

public delegate void UpdateTextCallback(string message);

private void TestThread()
{
    for (int i = 0; i <= 1000000000; i++)
    {
        Thread.Sleep(1000);                
        richTextBox1.Dispatcher.Invoke(
            new UpdateTextCallback(this.UpdateText),
            new object[] { i.ToString() }
        );
    }
}
private void UpdateText(string message)
{
    richTextBox1.AppendText(message + "\n");
}

private void button1_Click(object sender, RoutedEventArgs e)
{
   Thread test = new Thread(new ThreadStart(TestThread));
   test.Start();
}

TestThread method is used by thread named test to update textBox

I know this is a late response, but a neat way of doing this is to ping the broadcast address which populates your local arp cache.

This can then be shown by running arp -a which will list all the addresses in you local arp table.

ping 192.168.1.255
arp -a

Hopefully this is a nice neat option that people can use.

Check if other view has the property match_parent or fill_parent ,those properties may cover your ImageView which has shown in your RelativeLayout.By the way,the accepted answer does not work in my case.

After executing

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.3 -Dpackaging=jar -Dfile=ojdbc6.jar -DgeneratePom=true

check your .m2 repository folder (/com/oracle/ojdbc6/11.2.0.3) to see if ojdbc6.jar exists. If not check your maven repository settings under $M2_HOME/conf/settings.xml

You should use the Android AccountManager. It's purpose-built for this scenario. It's a little bit cumbersome but one of the things it does is invalidate the local credentials if the SIM card changes, so if somebody swipes your phone and throws a new SIM in it, your credentials won't be compromised.

This also gives the user a quick and easy way to access (and potentially delete) the stored credentials for any account they have on the device, all from one place.

SampleSyncAdapter (like @Miguel mentioned) is an example that makes use of stored account credentials.

Not really anything to do with jQuery, but if you want to trim a pattern from a string, then use a regular expression:

<textarea id="ta0"></textarea>
<button onclick="
  var ta = document.getElementById('ta0');
  var text = 'some<br>text<br />to<br/>replace';
  var re = /<br *\/?>/gi;
  ta.value = text.replace(re, '\n');
">Add stuff to text area</button>

Open the Run Configuration for your application (Run/Run Configurations..., then look for the applications entry in 'Java application').

The arguments tab has a text box Vm arguments, enter -Xss1m (or a bigger parameter for the maximum stack size). The default value is 512 kByte (SUN JDK 1.5 - don't know if it varies between vendors and versions).

Solution in Kotlin:

val nowInEpoch = Instant.now().epochSecond

Make sure your minimum SDK version is 26.

The question is dead but still knowing one more way doesn't hurt:

my_list = [ (old1, new1), (old2, new2), (old3, new3), ... (oldN, newN)]

for first,*args in my_list:
    if first == Value:
        PAIR_FOUND = True
        MATCHING_VALUE = args
        break

To obtain the File for a given Class, there are two steps:

1. Convert the Class to a URL
2. Convert the URL to a File

It is important to understand both steps, and not conflate them.

Once you have the File, you can call getParentFile to get the containing folder, if that is what you need.

Step 1: Class to URL

As discussed in other answers, there are two major ways to find a URL relevant to a Class.

1. URL url = Bar.class.getProtectionDomain().getCodeSource().getLocation();

2. URL url = Bar.class.getResource(Bar.class.getSimpleName() + ".class");

Both have pros and cons.

The getProtectionDomain approach yields the base location of the class (e.g., the containing JAR file). However, it is possible that the Java runtime's security policy will throw SecurityException when calling getProtectionDomain(), so if your application needs to run in a variety of environments, it is best to test in all of them.

The getResource approach yields the full URL resource path of the class, from which you will need to perform additional string manipulation. It may be a file: path, but it could also be jar:file: or even something nastier like bundleresource://346.fwk2106232034:4/foo/Bar.class when executing within an OSGi framework. Conversely, the getProtectionDomain approach correctly yields a file: URL even from within OSGi.

Note that both getResource("") and getResource(".") failed in my tests, when the class resided within a JAR file; both invocations returned null. So I recommend the #2 invocation shown above instead, as it seems safer.

Step 2: URL to File

Either way, once you have a URL, the next step is convert to a File. This is its own challenge; see Kohsuke Kawaguchi's blog post about it for full details, but in short, you can use new File(url.toURI()) as long as the URL is completely well-formed.

Lastly, I would highly discourage using URLDecoder. Some characters of the URL, : and / in particular, are not valid URL-encoded characters. From the URLDecoder Javadoc:

It is assumed that all characters in the encoded string are one of the following: "a" through "z", "A" through "Z", "0" through "9", and "-", "_", ".", and "*". The character "%" is allowed but is interpreted as the start of a special escaped sequence.

...

There are two possible ways in which this decoder could deal with illegal strings. It could either leave illegal characters alone or it could throw an IllegalArgumentException. Which approach the decoder takes is left to the implementation.

In practice, URLDecoder generally does not throw IllegalArgumentException as threatened above. And if your file path has spaces encoded as %20, this approach may appear to work. However, if your file path has other non-alphameric characters such as + you will have problems with URLDecoder mangling your file path.

Working code

To achieve these steps, you might have methods like the following:

/**
 * Gets the base location of the given class.
 * <p>
 * If the class is directly on the file system (e.g.,
 * "/path/to/my/package/MyClass.class") then it will return the base directory
 * (e.g., "file:/path/to").
 * </p>
 * <p>
 * If the class is within a JAR file (e.g.,
 * "/path/to/my-jar.jar!/my/package/MyClass.class") then it will return the
 * path to the JAR (e.g., "file:/path/to/my-jar.jar").
 * </p>
 *
