For those who are looking for the fastest way to iterate over strings in php, Ive prepared a benchmark testing.
The first method in which you access string characters directly by specifying its position in brackets and treating string like an array:

$string = "a sample string for testing";
$char = $string[4] // equals to m

I myself thought the latter is the fastest method, but I was wrong.
As with the second method (which is used in the accepted answer):

$string = "a sample string for testing";
$string = str_split($string);
$char = $string[4] // equals to m

This method is going to be faster cause we are using a real array and not assuming one to be an array.

Calling the last line of each of the above methods for 1000000 times lead to these benchmarking results:

Using string[i]
0.24960017204285 Seconds

Using str_split
0.18720006942749 Seconds

Which means the second method is way faster.

For Android Studio / intellij users:

• Select Version Control
• Select Log
• Right click the commit for which you want to rename
• Click Edit Commit Message
• Write your commit message
• Done

This is not perfect methods. You have to implement same way which is display here.

You can also call the image under the folder through the code you can use

Resources res = getResources();
Drawable shape = res. getDrawable(R.drawable.gradient_box);

TextView tv = (TextView)findViewByID(R.id.textview);
tv.setBackground(shape);

If you use Tomcat, add '-Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true' in VM properties.

First all answers are right, you can pass the data except custom objects by using Intent. If you want to pass the custom objects, you have to implement Serialazable or Parcelable to your custom object class. I thought it's too much complicated...

So if your project is simple, try to use DataCache. That provides super simple way for passing data. Ref: Github project CachePot

1- Set this to View or Activity or Fragment which will send data

DataCache.getInstance().push(obj);

2- Get data anywhere like below

public class MainFragment extends Fragment
{
    private YourObject obj;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        obj = DataCache.getInstance().pop(YourObject.class);

    }//end onCreate()
}//end class MainFragment

If you need to handle lists of different sizes, worry not! The wonderful itertools module has you covered:

>>> from itertools import zip_longest
>>> list1 = [1,2,1]
>>> list2 = [2,1,2,3]
>>> [sum(x) for x in zip_longest(list1, list2, fillvalue=0)]
[3, 3, 3, 3]
>>>

In Python 2, zip_longest is called izip_longest.

Excerpt:-

try 
        {
          cnt++;scnt++;now=System.currentTimeMillis();r=rand.nextInt(6);r++;
            loc=lm.getLastKnownLocation(best);
            if(loc!=null){lat=loc.getLatitude();lng=loc.getLongitude();}

            Thread.sleep(100);
            handler.sendMessage(handler.obtainMessage());
         } 
        catch (InterruptedException e) 
        {
            Toast.makeText(this, "Error="+e.toString(), Toast.LENGTH_LONG).show();
        }

As you can see above, a thread is running alongside main thread of user-interface activity which continuously displays GPS lat,long alongwith current time and a random dice throw.

IF you are curious then just check the full code: GPS Location with a randomized dice throw & current time in separate thread

In many cases some antivirus also start HyperV with window start and does not allow HAXM to install. I faced this issue because of AVAST antivirus. So I uninstalled AVAST, then HAXM installed properly after restart. Then I re-installed AVAST.

So its just a check while installing as now even with AVAST installed back, HAXM works properly with virtual box and android emulators.

There's no much point in doing that, because View should be generating html, not the controller. But anyways, you could use Controller.Content method, which gives you ability to specify result html, also content-type and encoding

public ActionResult Index()
{
    return Content("<html></html>");
}

Or you could use the trick built in asp.net-mvc framework - make the action return string directly. It will deliver string contents into users's browser.

public string Index()
{
    return "<html></html>";
}

In fact, for any action result other than ActionResult, framework tries to serialize it into string and write to response.

This was too good of an answer not to post it here. It's from a Gilles, a fellow user from askubuntu:

The clipboard is provided by the X server. It doesn't matter whether the server is headless or not, what matters is that your local graphical session is available to programs running on the remote machine. Thanks to X's network-transparent design, this is possible.

I assume that you're connecting to the remote server with SSH from a machine running Linux. Make sure that X11 forwarding is enabled both in the client configuration and in the server configuration. In the client configuration, you need to have the line ForwardX11 yes in ~/.ssh/config to have it on by default, or pass the option -X to the ssh command just for that session. In the server configuration, you need to have the line X11Forwarding yes in /etc/ssh/sshd_config (it is present by default on Ubuntu).

To check whether X11 forwarding is enabled, look at the value of the DISPLAY environment variable: echo $DISPLAY. You should see a value like localhost:10 (applications running on the remote machine are told to connect to a display running on the same machine, but that display connection is in fact forwarded by SSH to your client-side display). Note that if DISPLAY isn't set, it's no use setting it manually: the environment variable is always set correctly if the forwarding is in place. If you need to diagnose SSH connection issues, pass the option -vvv to ssh to get a detailed trace of what's happening.

If you're connecting through some other means, you may or may not be able to achieve X11 forwarding. If your client is running Windows, PuTTY supports X11 forwarding; you'll have to run an X server on the Windows machine such as Xming.

var text ="";
for (var member in list) {
        text += list[member];
}

I had this happen repeatedly after adding images to a project in Eclipse and making them part of the build path. The solution was to right-click on the class containing the main method, and then choose Run As -> Java Application. It seems that when you add a file to the build path, Eclipse automatically assumes that file is where the main method is. By going through the Run As menu instead of just clicking the green Run As button, it allows you to specify the correct entry-point.

I had the same issue. adding

<mvc:annotation-driven />
<mvc:default-servlet-handler />

to the spring-xml solved it

The most beginner-friendly solution is:

Drag a Timer from the Toolbox, give it a Name, set your desired Interval, and set "Enabled" to True. Then double-click the Timer and Visual Studio (or whatever you are using) will write the following code for you:

private void wait_Tick(object sender, EventArgs e)
{
    refreshText(); // Add the method you want to call here.
}

No need to worry about pasting it into the wrong code block or something like that.

There is a module called HttpHeadersMoreModule that gives you more control over headers. It does not come with Nginx and requires additional installation. With it, you can do something like this:

location ... {
  more_set_headers "Server: my_server";
}

That will "set the Server output header to the custom value for any status code and any content type". It will replace headers that are already set or add them if unset.

wget is capable of doing what you are asking. Just try the following:

wget -p -k http://www.example.com/

The -p will get you all the required elements to view the site correctly (css, images, etc). The -k will change all links (to include those for CSS & images) to allow you to view the page offline as it appeared online.

From the Wget docs:

‘-k’
‘--convert-links’
After the download is complete, convert the links in the document to make them
suitable for local viewing. This affects not only the visible hyperlinks, but
any part of the document that links to external content, such as embedded images,
links to style sheets, hyperlinks to non-html content, etc.

Each link will be changed in one of the two ways:

    The links to files that have been downloaded by Wget will be changed to refer
    to the file they point to as a relative link.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
    downloaded, then the link in doc.html will be modified to point to
    ‘../bar/img.gif’. This kind of transformation works reliably for arbitrary
    combinations of directories.

    The links to files that have not been downloaded by Wget will be changed to
    include host name and absolute path of the location they point to.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
    ../bar/img.gif), then the link in doc.html will be modified to point to
    http://hostname/bar/img.gif. 

Because of this, local browsing works reliably: if a linked file was downloaded,
the link will refer to its local name; if it was not downloaded, the link will
refer to its full Internet address rather than presenting a broken link. The fact
that the former links are converted to relative links ensures that you can move
the downloaded hierarchy to another directory.

Note that only at the end of the download can Wget know which links have been
downloaded. Because of that, the work done by ‘-k’ will be performed at the end
of all the downloads. 

Even more simple answer to you question would be:

echo "0 1 * * * /root/test.sh" | tee -a /var/spool/cron/root

You can setup cronjobs on remote servers as below:

#!/bin/bash
servers="srv1 srv2 srv3 srv4 srv5"
for i in $servers
  do
  echo "0 1 * * * /root/test.sh" | ssh $i " tee -a /var/spool/cron/root"
done

In Linux, the default location of the crontab file is /var/spool/cron/. Here you can find the crontab files of all users. You just need to append your cronjob entry to the respective user's file. In the above example, the root user's crontab file is getting appended with a cronjob to run /root/test.sh every day at 1 AM.

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

I am doing some large calculations which involves the mysql connection to stay long time and with heavy data. i was facing this "Mysql go away issue". So i tried t optimize the queries but that doen't helped me then i increased the mysql variables limit which is set to a lower value by default.

wait_timeout max_allowed_packet

To the limit what ever suits to you it should be the Any Number * 1024(Bytes). you can login to terminal using 'mysql -u username - p' command and can check and change for these variable limits.

Make sure that the column values u added in entity class having get set properties also in the same order which is present in target table.

If you are using Jupyter in anaconda, after conda update scikit-learn in terminal, close anaconda and restart, otherwise the error will occur again.

• Angular 2 and up
• Bootstrap css (animation is preserved)
• NO JQuery
• NO bootstrap.js
• Supports custom modal content (just like accepted answer)
• Recently added support for multiple modals on top of each other.

  }

  public onContainerClicked(event: MouseEvent): void {
    if ((<HTMLElement>event.target).classList.contains('modal')) {
      this.hide();
    }
  }
}

To show the backdrop, you'll need something like this CSS:

.modal {
  background: rgba(0,0,0,0.6);
}

The example now allows for multiple modals at the same time. (see the onContainerClicked() method).

For Bootstrap 4 css users, you need to make 1 minor change (because a css class name was updated from Bootstrap 3). This line: [ngClass]="{'in': visibleAnimate}" should be changed to: [ngClass]="{'show': visibleAnimate}"

To demonstrate, here is a plunkr

here it is a FULL WORKING example for iOS 7, 8, 9, 10 how to change app orientation to its current opposite

Objective-C

- (void)flipOrientation
{
    NSNumber *value;
    UIInterfaceOrientation currentOrientation = [[UIApplication sharedApplication] statusBarOrientation];
    if(UIInterfaceOrientationIsPortrait(currentOrientation))
    {
        if(currentOrientation == UIInterfaceOrientationPortrait)
        {
            value = [NSNumber numberWithInt:UIInterfaceOrientationPortraitUpsideDown];
        }
        else //if(currentOrientation == UIInterfaceOrientationPortraitUpsideDown)
        {
            value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
        }
    }
    else
    {
        if(currentOrientation == UIInterfaceOrientationLandscapeRight)
        {
            value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft];
        }
        else //if(currentOrientation == UIInterfaceOrientationLandscapeLeft)
        {
            value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeRight];
        }
    }
    [[UIDevice currentDevice] setValue:value forKey:@"orientation"];
    [UIViewController attemptRotationToDeviceOrientation];
}

Swift 3

func flipOrientation() -> Void
{
    let currentOrientation : UIInterfaceOrientation = UIApplication.shared.statusBarOrientation
    var value : Int = 0;
    if(UIInterfaceOrientationIsPortrait(currentOrientation))
    {
        if(currentOrientation == UIInterfaceOrientation.portrait)
        {
            value = UIInterfaceOrientation.portraitUpsideDown.rawValue
        }
        else //if(currentOrientation == UIInterfaceOrientation.portraitUpsideDown)
        {
            value = UIInterfaceOrientation.portrait.rawValue
        }
    }
    else
    {
        if(currentOrientation == UIInterfaceOrientation.landscapeRight)
        {
            value = UIInterfaceOrientation.landscapeLeft.rawValue
        }
        else //if(currentOrientation == UIInterfaceOrientation.landscapeLeft)
        {
            value = UIInterfaceOrientation.landscapeRight.rawValue
        }
    }
    UIDevice.current.setValue(value, forKey: "orientation")
    UIViewController.attemptRotationToDeviceOrientation()
}

Another way

setlocal enabledelayedexpansion
@echo off
for /f "delims=" %%i in (filename.txt) do (
if 1==1 (
set first_line=%%i
echo !first_line!
goto :eof
))

I tried exiting application using following code snippet, this it worked for me. Hope this helps you. i did small demo with 2 activities

first activity

public class MainActivity extends Activity implements OnClickListener{
    private Button secondActivityBtn;
    private SharedPreferences pref;
    private SharedPreferences.Editor editer;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        secondActivityBtn=(Button) findViewById(R.id.SecondActivityBtn);
        secondActivityBtn.setOnClickListener(this);

        pref = this.getSharedPreferences("MyPrefsFile", MODE_PRIVATE);
        editer = pref.edit();

        if(pref.getInt("exitApp", 0) == 1){
            editer.putInt("exitApp", 0);
            editer.commit();
            finish();
        }
    }
    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.SecondActivityBtn:
            Intent intent= new Intent(MainActivity.this, YourAnyActivity.class);
            startActivity(intent);
            break;
        default:
            break;
        }
    }
}

your any other activity

public class YourAnyActivity extends Activity implements OnClickListener {
    private Button exitAppBtn;
    private SharedPreferences pref;
    private SharedPreferences.Editor editer;

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

        exitAppBtn = (Button) findViewById(R.id.exitAppBtn);
        exitAppBtn.setOnClickListener(this);

        pref = this.getSharedPreferences("MyPrefsFile", MODE_PRIVATE);
        editer = pref.edit();
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.exitAppBtn:
            Intent main_intent = new Intent(YourAnyActivity.this,
                    MainActivity.class);
            main_intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(main_intent);
            editer.putInt("exitApp",1);
            editer.commit();
            break;
        default:
            break;
        }
    }
}

This is really easy using package lubridate. All you have to do is tell R what format your date is already in. It then converts it into the standard format

nzd$date <- dmy(nzd$date)

that's it.

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}
% ...    
\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

There is also another approach without the use of DomXPath or Zend_Dom_Query.

Based on dav's original function, I wrote the following function that returns all the children of the parent node whose tag and class match the parameters.

function getElementsByClass(&$parentNode, $tagName, $className) {
    $nodes=array();

    $childNodeList = $parentNode->getElementsByTagName($tagName);
    for ($i = 0; $i < $childNodeList->length; $i++) {
        $temp = $childNodeList->item($i);
        if (stripos($temp->getAttribute('class'), $className) !== false) {
            $nodes[]=$temp;
        }
    }

    return $nodes;
}

suppose you have a variable $html the following HTML:

<html>
 <body>
  <div id="content_node">
    <p class="a">I am in the content node.</p>
    <p class="a">I am in the content node.</p>
    <p class="a">I am in the content node.</p>    
  </div>
  <div id="footer_node">
    <p class="a">I am in the footer node.</p>
  </div>
 </body>
</html>

use of getElementsByClass is as simple as:

$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadHTML($html);
$content_node=$dom->getElementById("content_node");

$div_a_class_nodes=getElementsByClass($content_node, 'div', 'a');//will contain the three nodes under "content_node".

I came across this, and thought I'd throw in my 2 cents. Click on the column headers to sort ascending, and again to sort descending.

• Works in Chrome, Firefox, Opera AND IE(8)
• Only uses JQuery
• Does alpha and numeric sorting - ascending and descending

$('th').click(function(){_x000D_
    var table = $(this).parents('table').eq(0)_x000D_
    var rows = table.find('tr:gt(0)').toArray().sort(comparer($(this).index()))_x000D_
    this.asc = !this.asc_x000D_
    if (!this.asc){rows = rows.reverse()}_x000D_
    for (var i = 0; i < rows.length; i++){table.append(rows[i])}_x000D_
})_x000D_
function comparer(index) {_x000D_
    return function(a, b) {_x000D_
        var valA = getCellValue(a, index), valB = getCellValue(b, index)_x000D_
        return $.isNumeric(valA) && $.isNumeric(valB) ? valA - valB : valA.toString().localeCompare(valB)_x000D_
    }_x000D_
}_x000D_
function getCellValue(row, index){ return $(row).children('td').eq(index).text() }

table, th, td {_x000D_
    border: 1px solid black;_x000D_
}_x000D_
th {_x000D_
    cursor: pointer;_x000D_

Note that in an attribute selector (e.g., [attr~=value]), the tilde

Represents an element with an attribute name of attr whose value is a whitespace-separated list of words, one of which is exactly value.

If you mean the type of procedure you find in SQL Server, prior to 2010, you can't. If you want a query that accepts a parameter, you can use the query design window:

 PARAMETERS SomeParam Text(10);
 SELECT Field FROM Table
 WHERE OtherField=SomeParam

You can also say:

CREATE PROCEDURE ProcedureName
   (Parameter1 datatype, Parameter2 datatype) AS
   SQLStatement

From: http://msdn.microsoft.com/en-us/library/aa139977(office.10).aspx#acadvsql_procs

Note that the procedure contains only one statement.

If you want to create a .war file you can deploy to a Tomcat instance using the Manager app, create a folder, put all your files in that folder (including an index.html file) move your terminal window into that folder, and execute the following command:

zip -r <AppName>.war *

I've tested it with Tomcat 8 on the Mac, but it should work anywhere

Extract characters from a string:

var str = "Hello world!";
var res = str.substring(1,4);

The result of res will be:

If you are just looking to get a single value from the XML you may want to use Java's XPath library. For an example see my answer to a previous question:

• How to use XPath on xml docs having default namespace

It would look something like:

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathConstants;
import javax.xml.xpath.XPathFactory;

import org.w3c.dom.Document;
import org.w3c.dom.NodeList;

public class Demo {

    public static void main(String[] args) {
        DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
        try {
            DocumentBuilder builder = domFactory.newDocumentBuilder();
            Document dDoc = builder.parse("E:/test.xml");

            XPath xPath = XPathFactory.newInstance().newXPath();
            Node node = (Node) xPath.evaluate("/Request/@name", dDoc, XPathConstants.NODE);

        } catch (Exception e) {
            e.printStackTrace();

    }

}

Without using find:

du -a $directory | awk '{print $2}' | grep '\.in$'

No, you must have an Intel Mac of some sort. I went to Best Buy and got a 24" iMac with 4G RAM for $1499 using their 18 month no interest promotion. I pay a minimum payment of something like $16 a month. As long as I pay the entire thing off within 18 months - no interest. That was the only way I was getting into iPhone development.

You can use toStringAsFixed in order to display the limited digits after decimal points. toStringAsFixed returns a decimal-point string-representation. toStringAsFixed accepts an argument called fraction Digits which is how many digits after decimal we want to display. Here is how to use it.

double pi = 3.1415926;
const val = pi.toStringAsFixed(2); // 3.14

I had a very similar issue. I got the same error because the csv contained spaces in the header. My csv contained a header "Gender " and I had it listed as:

[['Gender']]

If it's easy enough for you to access your csv, you can use the excel formula trim() to clip any spaces of the cells.

or remove it like this

df.columns = df.columns.to_series().apply(lambda x: x.strip())

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

Although it is very old question, but as i didn't find a one liner, i made one.

# original numbers in list
l = [1, 2, 2, 3, 3, 3, 4]

# empty dictionary to hold pair of number and its count
d = {}

# loop through all elements and store count
[ d.update( {i:d.get(i, 0)+1} ) for i in l ]

print(d)

Semantically speaking, wouldn't it be best to use an ordered or unordered list and then style it appropriately using CSS?

<ul id="[UL_ID]">
    <li><img src="[image1_url]" alt="img1" /></li>
    <li><img src="[image2_url]" alt="img2" /></li>
    <li><img src="[image3_url]" alt="img3" /></li>
    <li><img src="[image4_url]" alt="img4" /></li>
    <li><img src="[image5_url]" alt="img5" /></li>
    <li><img src="[image6_url]" alt="img6" /></li>
</ul>

Using CSS, you'll be able to style this whatever way you want and remove the whitespace imbetween the books.

The previous answers contain a lot of information, but I think there is a philosophical difference that hasn't been pointed out. SOAP was the answer to "how to we create a modern, object-oriented, platform and protocol independent successor to RPC?". REST developed from the question, "how to we take the insights that made HTTP so successful for the web, and use them for distributed computing?"

SOAP is a about giving you tools to make distributed programming look like ... programming. REST tries to impose a style to simplify distributed interfaces, so that distributed resources can refer to each other like distributed html pages can refer to each other. One way it does that is attempt to (mostly) restrict operations to "CRUD" on resources (create, read, update, delete).

REST is still young -- although it is oriented towards "human readable" services, it doesn't rule out introspection services, etc. or automatic creation of proxies. However, these have not been standardized (as I write). SOAP gives you these things, but (IMHO) gives you "only" these things, whereas the style imposed by REST is already encouraging the spread of web services because of its simplicity. I would myself encourage newbie service providers to choose REST unless there are specific SOAP-provided features they need to use.

In my opinion, then, if you are implementing a "greenfield" API, and don't know that much about possible clients, I would choose REST as the style it encourages tends to help make interfaces comprehensible, and easy to develop to. If you know a lot about client and server, and there are specific SOAP tools that will make life easy for both, then I wouldn't be religious about REST, though.

One example in order to understand, where the usage of ZEROFILL might be interesting:

In Germany, we have 5 digit zipcodes. However, those Codes may start with a Zero, so 80337 is a valid zipcode for munic, 01067 is a zipcode of Berlin.

As you see, any German citizen expects the zipcodes to be displayed as a 5 digit code, so 1067 looks strange.

In order to store those data, you could use a VARCHAR(5) or INT(5) ZEROFILL whereas the zerofilled integer has two big advantages:

1. Lot lesser storage space on hard disk
2. If you insert 1067, you still get 01067 back

Maybe this example helps understanding the use of ZEROFILL.

If anyone is looking for a VB.Net answer (as I was initially), here it is:

Public Function IsSatisfied() As Expression(Of Func(Of Charity, String, String, Boolean))

Return Function(charity, name, referenceNumber) (String.IsNullOrWhiteSpace(name) Or
                                                         charity.registeredName.ToLower().Contains(name.ToLower()) Or
                                                         charity.alias.ToLower().Contains(name.ToLower()) Or
                                                         charity.charityId.ToLower().Contains(name.ToLower())) And
                                                    (String.IsNullOrEmpty(referenceNumber) Or
                                                     charity.charityReference.ToLower().Contains(referenceNumber.ToLower()))
End Function

This should work, try;

Add a System Reference.

using System.Diagnostics;

Then use this code to run your command in a hiden CMD Window.

Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
cmd.StartInfo.Arguments = "Enter your command here";
cmd.Start();

Without knowing the ID of the DIV I think you could select the IMG like this:

$("#"+$(this).attr("id")+" img:first")

This does the trick...

<item >
    <shape android:shape="rectangle">
        <solid android:color="#YOUR_BOTTOM_LINE_COLOR"/>
    </shape>
</item>

<item android:bottom="1.5dp">
    <shape android:shape="rectangle">
        <solid android:color="#YOUR_BG_COLOR"/>
    </shape>
</item>

The simplest supported solution is to either use margin

.element {
  display: block;
  margin: 0px auto;
}

Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto if it did exist.

CSS

.element_wrapper {
  display: block;
  margin: 0px auto;
}
.element {
  background: blue;
}

HTML

<div class="element_wrapper">
  <div class="element">
    Hello world
  </div>
</div>

Just use the length property of a JavaScript array like so:

$scope.names.length

Also, I don't see a starting <script> tag in your code.

If you want the length inside your view, do it like so:

{{ names.length }}

How about using strtr() to substitute all of your other delimiters with the first one?

private function multiExplode($delimiters,$string) {
    return explode(
        $delimiters[0],
        strtr(
            $string,
            array_combine(
                array_slice(    $delimiters, 1  ),
                array_fill(
                    0,
                    count($delimiters)-1,
                    array_shift($delimiters)
                )
            )
        )
    );
}

It's sort of unreadable, I guess, but I tested it as working over here.

One-liners ftw!

Think of "BeforeClass" as a static initializer for your test case - use it for initializing static data - things that do not change across your test cases. You definitely want to be careful about static resources that are not thread safe.

Finally, use the "AfterClass" annotated method to clean up any setup you did in the "BeforeClass" annotated method (unless their self destruction is good enough).

"Before" & "After" are for unit test specific initialization. I typically use these methods to initialize / re-initialize the mocks of my dependencies. Obviously, this initialization is not specific to a unit test, but general to all unit tests.

I use href to load the modal and leave data-toggle for the tooltip:

<a 
    data-toggle="tooltip"
    data-placement="top"
    title="My Tooltip text!"
    href="javascript:$('#id').modal('show');"
>
+
</a>

I am surprised that such a basic question doesn't seem to have an immediate answer in python. It seems to me that nearly all proposed answers use some kind of type checking, that is usually not advised in python and they seem restricted to a specific case (they fail with different numerical types or generic iteratable objects that are not tuples or lists).

For me, what works better is importing numpy and using array.size, for example:

>>> a=1
>>> np.array(a)
Out[1]: array(1)

>>> np.array(a).size
Out[2]: 1

>>> np.array([1,2]).size
Out[3]: 2

>>> np.array('125')
Out[4]: 1

Note also:

>>> len(np.array([1,2]))

Out[5]: 2

but:

>>> len(np.array(a))
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

Since header files from some C libraries use the keyword, the C++ language will have to do something about it.. at the minimum, ignoring the keyword, so we don't have to #define the keyword to a blank macro to suppress the keyword.

Most of the answers here have suggested to either use hiveconf or hivevar namespace to store the variable. And all those answers are right. However, there is one more namespace.

There are total three namespaces available for holding variables.

1. hiveconf - hive started with this, all the hive configuration is stored as part of this conf. Initially, variable substitution was not part of hive and when it got introduced, all the user-defined variables were stored as part of this as well. Which is definitely not a good idea. So two more namespaces were created.
2. hivevar: To store user variables
3. system: To store system variables.

And so if you are storing a variable as part of a query (i.e. date or product_number) you should use hivevar namespace and not hiveconf namespace.

And this is how it works.

hiveconf is still the default namespace, so if you don't provide any namespace it will store your variable in hiveconf namespace.

However, when it comes to referring a variable, it's not true. By default it refers to hivevar namespace. Confusing, right? It can become clearer with the following example.

If you do not provide namespace as mentioned below, variable var will be stored in hiveconf namespace.

set var="default_namespace";

So, to access this you need to specify hiveconf namespace

select ${hiveconf:var};

And if you do not provide namespace it will give you an error as mentioned below, reason being that by default if you try to access a variable it checks in hivevar namespace only. And in hivevar there is no variable named var

select ${var}; 

We have explicitly provided hivevar namespace

set hivevar:var="hivevar_namespace";

as we are providing the namespace this will work.

select ${hivevar:var}; 

And as default, workspace used during referring a variable is hivevar, the following will work too.

select ${var};

Add simple style to your button

.btn {
    background: none;
    color: inherit;
    border: none;
    padding: 0;
    font: inherit;
    cursor: pointer;
    outline: inherit;
}

This is an example where I use the table variable to list multiple values in an IN clause. The obvious reason is to be able to change the list of values only one place in a long procedure.

To make it even more dynamic and alowing user input, I suggest declaring a varchar variable for the input, and then using a WHILE to loop trough the data in the variable and insert it into the table variable.

Replace @your_list, Your_table and the values with real stuff.

DECLARE @your_list TABLE (list varchar(25)) 
INSERT into @your_list
VALUES ('value1'),('value2376')

SELECT *  
FROM your_table 
WHERE your_column in ( select list from @your_list )

The select statement abowe will do the same as:

SELECT *  
FROM your_table 
WHERE your_column in ('value','value2376' )

I know this question has already an answer that gives a solution. But I want to give you my two cents to help people to understand the problem. Getting same issue I've created a specific question. I got same problem, but only with PHPStorm. And exactly when I try to run test from the editor.

dyld is the dynamic linker

I sow that dyld was looking for /usr/local/lib/libpng15.15.dylib but inside my /usr/local/lib/ there was not. In that folder, I got libpng16.16.dylib.

Thanks to a comment, I undestand that my /usr/bin/php was a pointer to php 5.5.8. Instead, ... /usr/local/bin/php was 5.5.14. PHPStorm worked with /usr/bin/php that is default configuration. When I run php via console, I run /urs/local/bin/php.

So, ... If you get some dyld error, maybe you have some wrong php configuration. That's the reason because

$ brew update && brew upgrade
$ brew reinstall php55

But I dont know why this do not solve the problem to me. Maybe because I have

%d seems to be the norm for printing integers, I never figured out why, they behave identically.

Use the Chart Wizard.

On Step 2 of 4, there is a tab labeled "Series". There are 3 fields and a list box on this tab. The list box shows the different series you are already including on the chart. Each series has both a "Name" field and a "Values" field that is specific to that series. The final field is the "Category (X) axis labels" field, which is common to all series.

Click on the "Add" button below the list box. This will add a blank series to your list box. Notice that the values for "Name" and for "Values" change when you highlight a series in the list box.

Select your new series.

There is an icon in each field on the right side. This icon allows you to select cells in the workbook to pull the data from. When you click it, the Wizard temporarily hides itself (except for the field you are working in) allowing you to interact with the workbook.

Select the appropriate sheet in the workbook and then select the fields with the data you want to show in the chart. The button on the right of the field can be clicked to unhide the wizard.

Hope that helps.

EDIT: The above applies to 2003 and before. For 2007, when the chart is selected, you should be able to do a similar action using the "Select Data" option on the "Design" tab of the ribbon. This opens up a dialog box listing the Series for the chart. You can select the series just as you could in Excel 2003, but you must use the "Add" and "Edit" buttons to define custom series.

I tried this tool and it gave me good results.

You can only have one return value whereas you can have multiple out parameters.

You only need to consider out parameters in those cases.

However, if you need to return more than one parameter from your method, you probably want to look at what you're returning from an OO approach and consider if you're better off return an object or a struct with these parameters. Therefore you're back to a return value again.

If you run the GWT compiler with the -localWorkers flag, the compiler will compile multiple permutations in parallel. This lets you use all the cores of a multi-core machine, for example -localWorkers 2 will tell the compiler to do compile two permutations in parallel. You won't get order of magnitudes differences (not everything in the compiler is parallelizable) but it is still a noticable speedup if you are compiling multiple permutations.

If you're willing to use the trunk version of GWT, you'll be able to use hosted mode for any browser (out of process hosted mode), which alleviates most of the current issues with hosted mode. That seems to be where the GWT is going - always develop with hosted mode, since compiles aren't likely to get magnitudes faster.

To get the output of ls, use stdout=subprocess.PIPE.

>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo

The command cdrecord --help outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.

>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.

subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

As mentioned by Chris Morgan, you should be using proc.communicate() instead of proc.read().

>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout: 
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

Believe it or not, I have found cases where this problem occurred due to a build error when the build error was due to an error in xcopy in the pre-build events.

We had this problem at a colleges computer, and after trying everything here we set to forget it and fix the error from xcopy. When this was fixed the Visual Studio 2010 shell error stopped popping up, for some reason.

As detailed above, the generic List<> is the best way of doing it.

If you're stuck in .NET 1.*, then you will have to use the ArrayList class instead. This does not have compile-time type checking and you also have to add casting - messy.

Successive versions have also implemented various variations - including thread safe variants.

value = Math.Truncate(100 * value) / 100;

Beware that fractions like these cannot be accurately represented in floating point.

I would go with x.equals(y) because that's consistent way to check equality for all classes.

As far as performance goes, equals is actually more expensive because it ends up calling intValue().

EDIT: You should avoid autoboxing in most cases. It can get really confusing, especially the author doesn't know what he was doing. You can try this code and you will be surprised by the result;

Integer a = 128;
Integer b = 128;

System.out.println(a==b);

You can find what is the php.ini file used:

• By add phpinfo() in a php page and display the page (like the picture under)
• From the shell, enter: php -i

Next, you can find the information in the Loaded Configuration file (so here it's /user/local/etc/php/php.ini)

Sometimes, you have indicated (none), in this case you just have to put your custom php.ini that you can find here: http://git.php.net/?p=php-src.git;a=blob;f=php.ini-production;hb=HEAD

I hope this answer will help.

Old thread, but the question is still relevant, so...

(1) The example in your question now DOES work in Firefox. However in addition to calling the event handler (which displays an alert), it ALSO clicks on the link, causing navigation (once the alert is dismissed).

(2) To JUST call the event handler (without triggering navigation) merely replace:

document.getElementById('linkid').click();

with

document.getElementById('linkid').onclick();

you need the libblas and liblapack dev packages if you are using Ubuntu.

aptitude install libblas-dev liblapack-dev
pip install scipy

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

Constraints dictate what values are valid for data in the database. For example, you can enforce the a value is not null (a NOT NULL constraint), or that it exists as a unique constraint in another table (a FOREIGN KEY constraint), or that it's unique within this table (a UNIQUE constraint or perhaps PRIMARY KEY constraint depending on your requirements). More general constraints can be implemented using CHECK constraints.

The MSDN documentation for SQL Server 2008 constraints is probably your best starting place.

Check this link for steps on how to install express.js for your application locally.

But, if for some reason you are installing express globally, make sure the directory you are in is the directory where Node is installed. On my Windows 10, package.json is located at

C:\Program Files\nodejs\node_modules\npm

Open command prompt as administrator and change your directory to the location where your package.json is located.

Then issue the install command.

I had faced a similar issue with NodeJS, where the culprit was a forEach loop. Note that forEach is a synchronous function (NOT Asynchronous). Therefore it just ignores the promise returned. The solution was to use a for-of loop instead: Code where I got the error:

UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch()

is as follows:

permissionOrders.forEach( async(order) => {
        const requestPermissionOrder = new RequestPermissionOrderSchema({
            item: order.item,
            item_desc: order.item_desc,
            quantity: order.quantity,
            unit_price: order.unit_price,
            total_cost: order.total_cost,
            status: order.status,
            priority: order.priority,
            directOrder: order.directOrder
        });

        try {
            const dat_order = await requestPermissionOrder.save();
            res.json(dat_order);
        } catch(err){
            res.json({ message : err});
        }
    });

Solution for the above issue is as follows:

for (let order of permissionOrders){
        const requestPermissionOrder = new RequestPermissionOrderSchema({
            item: order.item,
            item_desc: order.item_desc,
            quantity: order.quantity,
            unit_price: order.unit_price,
            total_cost: order.total_cost,
            status: order.status,
            priority: order.priority,
            directOrder: order.directOrder
        });

        try {
            const dat_order = await requestPermissionOrder.save();
            res.json(dat_order);
        } catch(err){
            res.json({ message : err});
        }
    };

select * from *tablename* where 1 having length(*fieldname*)=*fieldlength*

Example if you want to select from customer the entry's with a name shorter then 2 chars.

select * from customer where 1 **having length(name)<2**

The ternary operator can only be the right side of an assignment and not a statement of its own.

Three types of commenting are supported

1. Hash base single line commenting using #

   Select * from users ; # this will list users
   

   2. Double Dash commenting using --

   Select * from users ; -- this will list users

Note : Its important to have single white space just after --

3) Multi line commenting using /* */

Select * from users ; /* this will list users */

Batch files have really very limited logic powers so the best you can hope to come up with is a good workaround that indirectly achieves what you want. That's not to say that you should feel they are inferior to a real language - they still demand the same attention to detail and manual debugging as a real application. It's just that you'll need to work a lot harder to make them do what you want in a robust manner.

For the OP's question it sounds like you require two specific files to exist. Just use a tally:

IF EXIST somefile.txt (
    set /a file1_status=1
)

IF EXIST someotehrfile.txt (
    set /a file2_status=1
)

set /a file_status_result=file1_status + file2_status

if %file_status_result% equ 2 (
    goto somefileexists
)

goto exit

:somefileexists
IF EXIST someotherfile.txt SET var=...

:exit

My example uses 3 variables, but you could just add 1 to file_result_status if the file exists. But if you want more granular control later in your batch file you can record the result for each file as I have done so you don't have to keep checking if a file exists later on.

I did it this way and it worked for me like a charm.

var data = [{ id: 0, text: 'enhancement' }, { id: 1, text: 'bug' }, { id: 2, 

    text: 'duplicate' }, { id: 3, text: 'invalid' }, { id: 4, text: 'wontfix' }];

    $(".js-example-data-array").select2({
      data: data
    })

PreparedStatements are the way to go, because they make SQL injection impossible. Here's a simple example taking the user's input as the parameters:

public insertUser(String name, String email) {
   Connection conn = null;
   PreparedStatement stmt = null;
   try {
      conn = setupTheDatabaseConnectionSomehow();
      stmt = conn.prepareStatement("INSERT INTO person (name, email) values (?, ?)");
      stmt.setString(1, name);
      stmt.setString(2, email);
      stmt.executeUpdate();
   }
   finally {
      try {
         if (stmt != null) { stmt.close(); }
      }
      catch (Exception e) {
         // log this error
      }
      try {
         if (conn != null) { conn.close(); }
      }
      catch (Exception e) {
         // log this error
      }
   }
}

No matter what characters are in name and email, those characters will be placed directly in the database. They won't affect the INSERT statement in any way.

There are different set methods for different data types -- which one you use depends on what your database fields are. For example, if you have an INTEGER column in the database, you should use a setInt method. The PreparedStatement documentation lists all the different methods available for setting and getting data.

Brace expansion doesn't work, but *, ? and [] do. If you set shopt -s extglob then you can also use extended pattern matching:

• ?() - zero or one occurrences of pattern
• *() - zero or more occurrences of pattern
• +() - one or more occurrences of pattern
• @() - one occurrence of pattern
• !() - anything except the pattern

Here's an example:

shopt -s extglob
for arg in apple be cd meet o mississippi
do
    # call functions based on arguments
    case "$arg" in
        a*             ) foo;;    # matches anything starting with "a"
        b?             ) bar;;    # matches any two-character string starting with "b"
        c[de]          ) baz;;    # matches "cd" or "ce"
        me?(e)t        ) qux;;    # matches "met" or "meet"
        @(a|e|i|o|u)   ) fuzz;;   # matches one vowel
        m+(iss)?(ippi) ) fizz;;   # matches "miss" or "mississippi" or others
        *              ) bazinga;; # catchall, matches anything not matched above
    esac
done

Using a guid

SELECT @randomString = CONVERT(varchar(255), NEWID())

very short ...

It could be doing the temp table renaming if you are trying to add a column to the beginning of the table (as this is easier than altering the order). Also, if there is data in the Employees table, it has to do insert select * so it can calculate the EmployeeID.

Just an alternative to the code by rkosegi,

BEGIN

    .. Declare statements ..

    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
    BEGIN
          .. set any flags etc  eg. SET @flag = 0; ..
          ROLLBACK;
    END;

    START TRANSACTION;

        .. Query 1 ..
        .. Query 2 ..
        .. Query 3 ..

    COMMIT;
    .. eg. SET @flag = 1; ..

END

Maybe you can use the onResourceRequested and onResourceReceived callbacks to detect asynchronous loading. Here's an example of using those callbacks from their documentation:

var page = require('webpage').create();
page.onResourceRequested = function (request) {
    console.log('Request ' + JSON.stringify(request, undefined, 4));
};
page.onResourceReceived = function (response) {
    console.log('Receive ' + JSON.stringify(response, undefined, 4));
};
page.open(url);

Also, you can look at examples/netsniff.js for a working example.

log in as root user:

sudo su

password:

then go and do what you want to do in var/www

If you want to keep your controller code clean, you can subclass UITextView like below, and change the class name in the Interface Builder.

RoundTextView.h

#import <UIKit/UIKit.h>
@interface RoundTextView : UITextView
@end

RoundTextView.m

#import "RoundTextView.h"
#import <QuartzCore/QuartzCore.h>
@implementation RoundTextView
-(id) initWithCoder:(NSCoder *)aDecoder {
    if (self = [super initWithCoder:aDecoder]) {
        [self.layer setBorderColor:[[[UIColor grayColor] colorWithAlphaComponent:0.333] CGColor]];
        [self.layer setBorderWidth:1.0];
        self.layer.cornerRadius = 5;
        self.clipsToBounds = YES;
    }
    return self;
}
@end

@Nicolai is correct about casting and why the condition is false for any data. i guess you prefer the first form because you want to avoid date manipulation on the input string, correct? you don't need to be afraid:

SELECT *
FROM table
WHERE update_date >= '2013-05-03'::date
AND update_date < ('2013-05-03'::date + '1 day'::interval);

set title color

btnGere.setTitleColor(#colorLiteral(red: 0, green: 0, blue: 0, alpha: 1), for: .normal)

By default Kubernetes looks in the public Docker registry to find images. If your image doesn't exist there it won't be able to pull it.

You can run a local Kubernetes registry with the registry cluster addon.

Then tag your images with localhost:5000:

docker tag aii localhost:5000/dev/aii

Push the image to the Kubernetes registry:

docker push localhost:5000/dev/aii

And change run-aii.yaml to use the localhost:5000/dev/aii image instead of aii. Now Kubernetes should be able to pull the image.

Alternatively, you can run a private Docker registry through one of the providers that offers this (AWS ECR, GCR, etc.), but if this is for local development it will be quicker and easier to get setup with a local Kubernetes Docker registry.

Another solution is:

>>> "".join(list(hex(255))[2:])
'ff'

Probably an archaic answer, but functional.

From MSDN Building a Single Page Application with ASP.NET and AngularJS (about 41 mins in).

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // ... possible routing etc.

        // Setup to return json and camelcase it!
        var formatter = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
        formatter.SerializerSettings.ContractResolver =
            new Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver();
    }

It should be current, I tried it and it worked.

Hit the F1 button, then type "Toggle Render Whitespace" or the parts of it you can remember :)

I use vscode version 1.22.2 so this could be a feature that did not exist back in 2015.

With Android Architecture Components through the use of LiveData this can be easily implemented with any type of Adapter. You simply have to do the following steps:

1. Setup your data to return from the Room Database as LiveData as in the example below:

@Dao
public interface CustomDAO{

@Query("SELECT * FROM words_table WHERE column LIKE :searchquery")
    public LiveData<List<Word>> searchFor(String searchquery);
}

2. Create a ViewModel object to update your data live through a method that will connect your DAO and your UI

public class CustomViewModel extends AndroidViewModel {

    private final AppDatabase mAppDatabase;

    public WordListViewModel(@NonNull Application application) {
        super(application);
        this.mAppDatabase = AppDatabase.getInstance(application.getApplicationContext());
    }

    public LiveData<List<Word>> searchQuery(String query) {
        return mAppDatabase.mWordDAO().searchFor(query);
    }

}

3. Call your data from the ViewModel on the fly by passing in the query through onQueryTextListener as below:

Inside onCreateOptionsMenu set your listener as follows

searchView.setOnQueryTextListener(onQueryTextListener);

Setup your query listener somewhere in your SearchActivity class as follows

private android.support.v7.widget.SearchView.OnQueryTextListener onQueryTextListener =
            new android.support.v7.widget.SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    getResults(query);
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    getResults(newText);
                    return true;
                }

                private void getResults(String newText) {
                    String queryText = "%" + newText + "%";
                    mCustomViewModel.searchQuery(queryText).observe(
                            SearchResultsActivity.this, new Observer<List<Word>>() {
                                @Override
                                public void onChanged(@Nullable List<Word> words) {
                                    if (words == null) return;
                                    searchAdapter.submitList(words);
                                }
                            });
                }
            };

Note: Steps (1.) and (2.) are standard AAC ViewModel and DAO implementation, the only real "magic" going on here is in the OnQueryTextListener which will update the results of your list dynamically as the query text changes.

If you need more clarification on the matter please don't hesitate to ask. I hope this helped :).

I usually do this in the thread handling the json response:

try {
  Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageUrl).getContent());
} catch (MalformedURLException e) {
  e.printStackTrace();
} catch (IOException e) {
  e.printStackTrace();
}

If you need to do transformations on the image, you'll want to create a Drawable instead of a Bitmap.

You can't do this: {this.state.arrayFromJson} As your error suggests what you are trying to do is not valid. You are trying to render the whole array as a React child. This is not valid. You should iterate through the array and render each element. I use .map to do that.

I am pasting a link from where you can learn how to render elements from an array with React.

http://jasonjl.me/blog/2015/04/18/rendering-list-of-elements-in-react-with-jsx/

Hope it helps!

I found the following removed the indent and the margin from both the left AND right sides, but allowed the bullets to remain left-justified below the text above it. Add this to your css file:

ul.noindent {
    margin-left: 5px;
    margin-right: 0px;
    padding-left: 10px;
    padding-right: 0px;
}

To use it in your html file add class="noindent" to the UL tag. I've tested w/FF 14 and IE 9.

I have no idea why browsers default to the indents, but I haven't really had a reason for changing them that often.

sometimes you need to set Padding, not Margin to make space between items smaller than default

I have made a couple prototypes to handle this for me.

// This is a safety check to make sure the prototype is not already defined.
Function.prototype.method = function (name, func) {
    if (!this.prototype[name]) {
        this.prototype[name] = func;
        return this;
    }
};

Date.method('endOfDay', function () {
    var date = new Date(this);
    date.setHours(23, 59, 59, 999);
    return date;
});

Date.method('startOfDay', function () {
    var date = new Date(this);
    date.setHours(0, 0, 0, 0);
    return date;
});

if you dont want the saftey check, then you can just use

Date.prototype.startOfDay = function(){
  /*Method body here*/
};

Example usage:

var date = new Date($.now()); // $.now() requires jQuery
console.log('startOfDay: ' + date.startOfDay());
console.log('endOfDay: ' + date.endOfDay());

May be below code can help:

<button type="submit" [attr.disabled]="!ngForm.valid ? true : null">Submit</button>

If you want to change inputs in an iframe then submit the form from that iframe, do this

...
var el = document.getElementById('targetFrame');

var doc, frame_win = getIframeWindow(el); // getIframeWindow is defined below

if (frame_win) {
  doc = (window.contentDocument || window.document);
}

if (doc) {
  doc.forms[0].someInputName.value = someValue;
  ...
  doc.forms[0].submit();
}
...

Normally, you can only do this if the page in the iframe is from the same origin, but you can start Chrome in a debug mode to disregard the same origin policy and test this on any page.

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

try this it is working

 MySqlCommand dbcmd = _conn.CreateCommand();
    dbcmd.CommandText = sqlCommandString;
    dbcmd.ExecuteNonQuery();
    long imageId = dbcmd.LastInsertedId;

The question has already been answered, but I thought I'd add an answer with more precise terminology and references to the C++ standard.

Two things are going on here, array parameters being adjusted to pointer parameters, and array arguments being converted to pointer arguments. These are two quite different mechanisms, the first is an adjustment to the actual type of the parameter, whereas the other is a standard conversion which introduces a temporary pointer to the first element.

Adjustments to your function declaration:

dcl.fct#5:

After determining the type of each parameter, any parameter of type “array of T” (...) is adjusted to be “pointer to T”.

So int arg[] is adjusted to be int* arg.

Conversion of your function argument:

conv.array#1

An lvalue or rvalue of type “array of N T” or “array of unknown bound of T” can be converted to a prvalue of type “pointer to T”. The temporary materialization conversion is applied. The result is a pointer to the first element of the array.

So in printarray(firstarray, 3);, the lvalue firstarray of type "array of 3 int" is converted to a prvalue (temporary) of type "pointer to int", pointing to the first element.

for .NET Core console apps you can do this 2 ways - from the launchsettings.json or the properties menu.

Launchsettings.json

or right click the project > properties > debug tab on left

see "Application Arguments:"

• this is " " (space) delimited, no need for any commas. just start typing. each space " " will represent a new input parameter.
• (whatever changes you make here will be reflected in the launchsettings.json file...)

Should the benchmark measure time/iteration or iterations/time, and why?

It depends on what you are trying to test.

If you are interested in latency, use time/iteration and if you are interested in throughput, use iterations/time.

_{UPD. The answer and demo are updated to align with latest Angular.}

You can subscribe to entire form changes due to the fact that FormGroup representing a form provides valueChanges property which is an Observerable instance:

this.form.valueChanges.subscribe(data => console.log('Form changes', data));

In this case you would need to construct form manually using FormBuilder. Something like this:

export class App {
  constructor(private formBuilder: FormBuilder) {
    this.form = formBuilder.group({
      firstName: 'Thomas',
      lastName: 'Mann'
    })

    this.form.valueChanges.subscribe(data => {
      console.log('Form changes', data)
      this.output = data
    })
  }
}

Check out valueChanges in action in this demo: http://plnkr.co/edit/xOz5xaQyMlRzSrgtt7Wn?p=preview

In my case, there is a single table which happens to be a device list from a router. If you wish to read the table using TR/TH/TD (row, header, data) instead of a matrix as mentioned above, you can do something like the following:

    List<TableRow> deviceTable = (from table in document.DocumentNode.SelectNodes(XPathQueries.SELECT_TABLE)
                                       from row in table?.SelectNodes(HtmlBody.TR)
                                       let rows = row.SelectSingleNode(HtmlBody.TR)
                                       where row.FirstChild.OriginalName != null && row.FirstChild.OriginalName.Equals(HtmlBody.T_HEADER)
                                       select new TableRow
                                       {
                                           Header = row.SelectSingleNode(HtmlBody.T_HEADER)?.InnerText,
                                           Data = row.SelectSingleNode(HtmlBody.T_DATA)?.InnerText}).ToList();
                                       }  

TableRow is just a simple object with Header and Data as properties. The approach takes care of null-ness and this case:

<tr>_x000D_
    <td width="28%">&nbsp;</td>_x000D_
</tr>

which is row without a header. The HtmlBody object with the constants hanging off of it are probably readily deduced but I apologize for it even still. I came from the world where if you have " in your code, it should either be constant or localizable.

jQuery

var list = $("#selectList");
$.each(items, function(index, item) {
  list.append(new Option(item.text, item.value));
});

Vanilla JavaScript

var list = document.getElementById("selectList");
for(var i in items) {
  list.add(new Option(items[i].text, items[i].value));
}

$this->db->query("update table_name set ts = now() where 1=1") also works for current time stamp!

Here's a complete example of an HTTP GET request with parameters using angular.js in ASP.NET MVC:

CONTROLLER:

public class AngularController : Controller
{
    public JsonResult GetFullName(string name, string surname)
    {
        System.Diagnostics.Debugger.Break();
        return Json(new { fullName = String.Format("{0} {1}",name,surname) }, JsonRequestBehavior.AllowGet);
    }
}

VIEW:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script type="text/javascript">
    var myApp = angular.module("app", []);

    myApp.controller('controller', function ($scope, $http) {

        $scope.GetFullName = function (employee) {

            //The url is as follows - ControllerName/ActionName?name=nameValue&surname=surnameValue

            $http.get("/Angular/GetFullName?name=" + $scope.name + "&surname=" + $scope.surname).
            success(function (data, status, headers, config) {
                alert('Your full name is - ' + data.fullName);
            }).
            error(function (data, status, headers, config) {
                alert("An error occurred during the AJAX request");
            });

        }
    });

<div ng-app="app" ng-controller="controller">

We just store the enum name itself - it's more readable.

We did mess around with storing specific values for enums where there are a limited set of values, e.g., this enum that has a limited set of statuses that we use a char to represent (more meaningful than a numeric value):

public enum EmailStatus {
    EMAIL_NEW('N'), EMAIL_SENT('S'), EMAIL_FAILED('F'), EMAIL_SKIPPED('K'), UNDEFINED('-');

    private char dbChar = '-';

    EmailStatus(char statusChar) {
        this.dbChar = statusChar;
    }

    public char statusChar() {
        return dbChar;
    }

    public static EmailStatus getFromStatusChar(char statusChar) {
        switch (statusChar) {
        case 'N':
            return EMAIL_NEW;
        case 'S':
            return EMAIL_SENT;
        case 'F':
            return EMAIL_FAILED;
        case 'K':
            return EMAIL_SKIPPED;
        default:
            return UNDEFINED;
        }
    }
}

and when you have a lot of values you need to have a Map inside your enum to keep that getFromXYZ method small.

The modern way is AuthenticationHandlers

in startup.cs add

services.AddAuthentication("BasicAuthentication").AddScheme<AuthenticationSchemeOptions, BasicAuthenticationHandler>("BasicAuthentication", null);

public class BasicAuthenticationHandler : AuthenticationHandler<AuthenticationSchemeOptions>
    {
        private readonly IUserService _userService;

        public BasicAuthenticationHandler(
            IOptionsMonitor<AuthenticationSchemeOptions> options,
            ILoggerFactory logger,
            UrlEncoder encoder,
            ISystemClock clock,
            IUserService userService)
            : base(options, logger, encoder, clock)
        {
            _userService = userService;
        }

        protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
        {
            if (!Request.Headers.ContainsKey("Authorization"))
                return AuthenticateResult.Fail("Missing Authorization Header");

            User user = null;
            try
            {
                var authHeader = AuthenticationHeaderValue.Parse(Request.Headers["Authorization"]);
                var credentialBytes = Convert.FromBase64String(authHeader.Parameter);
                var credentials = Encoding.UTF8.GetString(credentialBytes).Split(new[] { ':' }, 2);
                var username = credentials[0];
                var password = credentials[1];
                user = await _userService.Authenticate(username, password);
            }
            catch
            {
                return AuthenticateResult.Fail("Invalid Authorization Header");
            }

            if (user == null)
                return AuthenticateResult.Fail("Invalid User-name or Password");

            var claims = new[] {
                new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
                new Claim(ClaimTypes.Name, user.Username),
            };
            var identity = new ClaimsIdentity(claims, Scheme.Name);
            var principal = new ClaimsPrincipal(identity);
            var ticket = new AuthenticationTicket(principal, Scheme.Name);

            return AuthenticateResult.Success(ticket);
        }
    }

IUserService is a service that you make where you have user name and password. basically it returns a user class that you use to map your claims on.

var claims = new[] {
                new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
                new Claim(ClaimTypes.Name, user.Username),
            }; 

Then you can query these claims and her any data you mapped, ther are quite a few, have a look at ClaimTypes class

you can use this in an extension method an get any of the mappings

public int? GetUserId()
{
   if (context.User.Identity.IsAuthenticated)
    {
       var id=context.User.FindFirst(ClaimTypes.NameIdentifier);
       if (!(id is null) && int.TryParse(id.Value, out var userId))
            return userId;
     }
      return new Nullable<int>();
 }

This new way, i think is better than the old way as shown here, both work

public class BasicAuthenticationAttribute : AuthorizationFilterAttribute
{
    public override void OnAuthorization(HttpActionContext actionContext)
    {
        if (actionContext.Request.Headers.Authorization != null)
        {
            var authToken = actionContext.Request.Headers.Authorization.Parameter;
            // decoding authToken we get decode value in 'Username:Password' format
            var decodeauthToken = System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(authToken));
            // spliting decodeauthToken using ':'
            var arrUserNameandPassword = decodeauthToken.Split(':');
            // at 0th postion of array we get username and at 1st we get password
            if (IsAuthorizedUser(arrUserNameandPassword[0], arrUserNameandPassword[1]))
            {
                // setting current principle
                Thread.CurrentPrincipal = new GenericPrincipal(new GenericIdentity(arrUserNameandPassword[0]), null);
            }
            else
            {
                actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
            }
        }
        else
        {
            actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
        }
    }

    public static bool IsAuthorizedUser(string Username, string Password)
    {
        // In this method we can handle our database logic here...
        return Username.Equals("test") && Password == "test";
    }
}

These errors mean that the R code you are trying to run or source is not syntactically correct. That is, you have a typo.

To fix the problem, read the error message carefully. The code provided in the error message shows where R thinks that the problem is. Find that line in your original code, and look for the typo.

Prophylactic measures to prevent you getting the error again

The best way to avoid syntactic errors is to write stylish code. That way, when you mistype things, the problem will be easier to spot. There are many R style guides linked from the SO R tag info page. You can also use the formatR package to automatically format your code into something more readable. In RStudio, the keyboard shortcut CTRL + SHIFT + A will reformat your code.

Consider using an IDE or text editor that highlights matching parentheses and braces, and shows strings and numbers in different colours.

Common syntactic mistakes that generate these errors

Mismatched parentheses, braces or brackets

If you have nested parentheses, braces or brackets it is very easy to close them one too many or too few times.

{}}
## Error: unexpected '}' in "{}}"
{{}} # OK

Missing * when doing multiplication

This is a common mistake by mathematicians.

5x
Error: unexpected symbol in "5x"
5*x # OK

Not wrapping if, for, or return values in parentheses

This is a common mistake by MATLAB users. In R, if, for, return, etc., are functions, so you need to wrap their contents in parentheses.

if x > 0 {}
## Error: unexpected symbol in "if x"
if(x > 0) {} # OK

Not using multiple lines for code

Trying to write multiple expressions on a single line, without separating them by semicolons causes R to fail, as well as making your code harder to read.

x + 2 y * 3
## Error: unexpected symbol in "x + 2 y"
x + 2; y * 3 # OK

else starting on a new line

In an if-else statement, the keyword else must appear on the same line as the end of the if block.

if(TRUE) 1
else 2
## Error: unexpected 'else' in "else"    
if(TRUE) 1 else 2 # OK
if(TRUE) 
{
  1
} else            # also OK
{
  2
}

= instead of ==

= is used for assignment and giving values to function arguments. == tests two values for equality.

if(x = 0) {}
## Error: unexpected '=' in "if(x ="    
if(x == 0) {} # OK

Missing commas between arguments

When calling a function, each argument must be separated by a comma.

c(1 2)
## Error: unexpected numeric constant in "c(1 2"
c(1, 2) # OK

Not quoting file paths

File paths are just strings. They need to be wrapped in double or single quotes.

path.expand(~)
## Error: unexpected ')' in "path.expand(~)"
path.expand("~") # OK

Quotes inside strings

This is a common problem when trying to pass quoted values to the shell via system, or creating quoted xPath or sql queries.

Double quotes inside a double quoted string need to be escaped. Likewise, single quotes inside a single quoted string need to be escaped. Alternatively, you can use single quotes inside a double quoted string without escaping, and vice versa.

"x"y"
## Error: unexpected symbol in ""x"y"   
"x\"y" # OK
'x"y'  # OK  

Using curly quotes

So-called "smart" quotes are not so smart for R programming.

path.expand(“~”)
## Error: unexpected input in "path.expand(“"    
path.expand("~") # OK

Using non-standard variable names without backquotes

?make.names describes what constitutes a valid variable name. If you create a non-valid variable name (using assign, perhaps), then you need to access it with backquotes,

assign("x y", 0)
x y
## Error: unexpected symbol in "x y"
`x y` # OK

This also applies to column names in data frames created with check.names = FALSE.

dfr <- data.frame("x y" = 1:5, check.names = FALSE)
dfr$x y
## Error: unexpected symbol in "dfr$x y"
dfr[,"x y"] # OK
dfr$`x y`   # also OK

It also applies when passing operators and other special values to functions. For example, looking up help on %in%.

?%in%
## Error: unexpected SPECIAL in "?%in%"
?`%in%` # OK

Sourcing non-R code

The source function runs R code from a file. It will break if you try to use it to read in your data. Probably you want read.table.

source(textConnection("x y"))
## Error in source(textConnection("x y")) : 
##   textConnection("x y"):1:3: unexpected symbol
## 1: x y
##       ^

Corrupted RStudio desktop file

RStudio users have reported erroneous source errors due to a corrupted .rstudio-desktop file. These reports only occurred around March 2014, so it is possibly an issue with a specific version of the IDE. RStudio can be reset using the instructions on the support page.

Using expression without paste in mathematical plot annotations

When trying to create mathematical labels or titles in plots, the expression created must be a syntactically valid mathematical expression as described on the ?plotmath page. Otherwise the contents should be contained inside a call to paste.

plot(rnorm(10), ylab = expression(alpha ^ *)))
## Error: unexpected '*' in "plot(rnorm(10), ylab = expression(alpha ^ *"
plot(rnorm(10), ylab = expression(paste(alpha ^ phantom(0), "*"))) # OK

Use ElasticDump

1) yum install epel-release

2) yum install nodejs

3) yum install npm

4) npm install elasticdump

5) cd node_modules/elasticdump/bin

6)

./elasticdump \

Below is the configuration in Maven software by default in MAVEN_HOME\conf\settings.xml.

<settings>
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ~/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->

Add the below line under this configuration, will fulfill the requirement.

<localRepository>custom_path</localRepository>

Ex: <localRepository>D:/MYNAME/settings/.m2/repository</localRepository>

This landed in Chrome on 2012-08-26 Not sure about the exact version, I noticed it in Chrome 24.

A screenshot is worth a million words:

I am inspecting an object with methods in the Console. Clicking on the "Show function definition" takes me to the place in the source code where the function is defined. Or I can just hover over the function () { word to see function body in a tooltip. You can easily inspect the whole prototype chain like this! CDT definitely rock!!!

Hope you all find it helpful!

Download the appropriate postgres version here:

https://www.postgresql.org/download/

Make sure to run the following commands (the postgresql.org/download URL will generate the specific URL for you to use; the one I use below is just an example for centos 7) as sudo:

sudo yum install https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
sudo yum install postgresql11-server

your pg_dump version should now be updated, verify with pg_dump -V

Adding java.util.list will resolve your problem because List interface which you are trying to use is part of java.util.list package.

Assuming one has installed a JDK in /opt/java/jdk1.8.0_144 then:

1. Install the alternative for javac

   $ sudo update-alternatives --install /usr/bin/javac javac /opt/java/jdk1.8.0_144/bin/javac 1
   

2. Check / update the alternatives config:

   $ sudo update-alternatives --config javac
   

If there is only a single alternative for javac you will get a message saying so, otherwise select the option for the new JDK.

To check everything is setup correctly then:

$ which javac
/usr/bin/javac

$ ls -l /usr/bin/javac
lrwxrwxrwx 1 root root 23 Sep  4 17:10 /usr/bin/javac -> /etc/alternatives/javac

$ ls -l /etc/alternatives/javac
lrwxrwxrwx 1 root root 32 Sep  4 17:10 /etc/alternatives/javac -> /opt/java/jdk1.8.0_144/bin/javac

And finally

$ javac -version
javac 1.8.0_144

Repeat for java, keytool, jar, etc as needed.

Just to clarify my comment (it's illegible in a single line)

I think the best answer is the comment by Mike Chambers in this link (http://www.judahfrangipane.com/blog/2007/02/15/error-2032-stream-error/) by Hunter McMillen.

A note from Mike Chambers:

If you run into this using URLLoader, listen for the:

flash.events.HTTPStatusEvent.HTTP_STATUS

and in AIR :

flash.events.HTTPStatusEvent.HTTP_RESPONSE_STATUS

It should give you some more information (such as the status code being returned from the server).

jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

after that everything worked very well, even without any "-extension RANDR" switch.

getdate() 

is the direct equivalent, but you should always use UTC datetimes

getutcdate()

whether your app operates across timezones or not - otherwise you run the risk of screwing up date math at the spring/fall transitions

# cases
$x = null
$x = ''
$x = ' '

# test
if ($x -and $x.trim()) {'not empty'} else {'empty'}
or
if ([string]::IsNullOrWhiteSpace($x)) {'empty'} else {'not empty'}

You need to add the source from where you're loading the data.

For Example:

$("#step1Content").load("yourpage.html");

Hope It will help you.

You are confused on this.

A keystore is a container of certificates, private keys etc.

There are specifications of what should be the format of this keystore and the predominant is the #PKCS12

JKS is Java's keystore implementation. There is also BKS etc.

These are all keystore types.

So to answer your question:

difference between .keystore files and .jks files

There is none. JKS are keystore files. There is difference though between keystore types. E.g. JKS vs #PKCS12

if permission issue and you have ssh access in root folder

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

will resolve your error

I know this is so old, but i've landed on it , and the provided answers didn't works for me on powershell so after searching found this solution

to do it in powershell

Get-ChildItem -Path C:\Demo -Filter *.txt | Rename-Item -NewName {[System.IO.Path]::ChangeExtension($_.Name, ".old")}

credit goes to http://powershell-guru.com/powershell-tip-108-bulk-rename-extensions-of-files/

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

It turned out that TCP/IP was enabled for the IPv4 address, but not for the IPv6 address, of THESERVER.

Apparently some connection attempts ended up using IPv4 and others used IPv6.

Enabling TCP/IP for both IP versions resolved the issue.

The fact that SSMS worked turned out to be coincidental (the first few attempts presumably used IPv4). Some later attempts to connect through SSMS resulted in the same error message.

To enable TCP/IP for additional IP addresses:

• Start Sql Server Configuration Manager
• Open the node SQL Server Network Configuration
• Left-click Protocols for MYSQLINSTANCE
• In the right-hand pane, right-click TCP/IP
• Click Properties
• Select the IP Addresses tab
• For each listed IP address, ensure Active and Enabled are both Yes.

package main
import "fmt"
func main() {
  var x float64 = 5.7
  var y int = int(x)
  fmt.Println(y)  // outputs "5"
}

Try like this...

<script>
function getPaging(str) {
  $("#loading-content").load("dataSearch.php?"+str, hideLoader);
}
</script>

<li onclick="getPaging(this.id)" id="1">1</li>
<li onclick="getPaging(this.id)" id="2">2</li>

or unobtrusively

$(function() {
  $("li").on("click",function() {
    showLoader();
    $("#loading-content").load("dataSearch.php?"+this.id, hideLoader);
  });
});

using just

<li id="1">1</li>
<li id="2">2</li>

Another possibility of making.

actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0000ff")));

If you want to find the upstream for any branch (as opposed to just the one you are on), here is a slight modification to @cdunn2001's answer:

git rev-parse --abbrev-ref --symbolic-full-name YOUR_LOCAL_BRANCH_NAME@{upstream}

That will give you the remote branch name for the local branch named YOUR_LOCAL_BRANCH_NAME.

Yes, it creates a new list. This is by design.

The list will contain the same results as the original enumerable sequence, but materialized into a persistent (in-memory) collection. This allows you to consume the results multiple times without incurring the cost of recomputing the sequence.

The beauty of LINQ sequences is that they are composable. Often, the IEnumerable<T> you get is the result of combining multiple filtering, ordering, and/or projection operations. Extension methods like ToList() and ToArray() allow you to convert the computed sequence into a standard collection.

I've used most of the times the LIKE option and it works just fine. I just like to share one of my latest experiences where I used INSTR function. Regardless of the reasons that made me consider this options, what's important here is that the use is similar: instr(A, 'text 1') > 0 or instr(A, 'text 2') > 0 Another option could be: (instr(A, 'text 1') + instr(A, 'text 2')) > 0

I'd go with the LIKE '%text1%' OR LIKE '%text2%' option... if not hope this other option helps

std::vector<std::string> split(std::string text, char delim) {
    std::string line;
    std::vector<std::string> vec;
    std::stringstream ss(text);
    while(std::getline(ss, line, delim)) {
        vec.push_back(line);
    }
    return vec;
}

split("String will be split", ' ') -> {"String", "will", "be", "split"}

split("Hello, how are you?", ',') -> {"Hello", "how are you?"}

EDIT: Here's a thing I made, this can use multi-char delimiters, albeit I'm not 100% sure if it always works:

std::vector<std::string> split(std::string text, std::string delim) {
    std::vector<std::string> vec;
    size_t pos = 0, prevPos = 0;
    while (1) {
        pos = text.find(delim, prevPos);
        if (pos == std::string::npos) {
            vec.push_back(text.substr(prevPos));
            return vec;
        }

        vec.push_back(text.substr(prevPos, pos - prevPos));
        prevPos = pos + delim.length();
    }
}

If you wanted to keep it with just HTML and CSS you can use CSS Variables. Keep in mind, css variables aren't supported in IE.

<div class="thumb" style="--background: url('images/img.jpg')"></div> 

.thumb {
    background-image: var(--background);
}

I had a similar problem when I deployed my Flask app in the IIS. Apparently, IIS does not accept route that include an underline ("_"). When I removed the underline, problem was resolved.

If you want to check for local files first do:

@font-face {
font-family: 'Green Sans Web';
src:
    local('Green Web'),
    local('GreenWeb-Regular'),
    url('GreenWeb.ttf');
}

There is a more elaborate description of what to do here.

To UPLOAD a single file, you will need to create a bash script. Something like the following should work on OS X if you have sshpass installed.

Usage:

sftpx <password> <user@hostname> <localfile> <remotefile>

Put this script somewhere in your path and call it sftpx:

#!/bin/bash

export RND=`cat /dev/urandom | env LC_CTYPE=C tr -cd 'a-f0-9' | head -c 32`
export TMPDIR=/tmp/$RND
export FILENAME=$(basename "$4")
export DSTDIR=$(dirname "$4")

mkdir $TMPDIR
cp "$3" $TMPDIR/$FILENAME

export SSHPASS=$1
sshpass -e sftp -oBatchMode=no -b - $2 << !
   lcd $TMPDIR
   cd $DSTDIR
   put $FILENAME
   bye
!

rm $TMPDIR/$FILENAME
rmdir $TMPDIR

Since this topic never received a verified solution, I can offer a simple solution to the two issues I see you asked solutions for.

1. Replacing the "." character when value is a string

The string class offers a replace method for the string object you want to update:

Example:

$myString = $myString.replace(".","") 

2. Converting the string value to an integer

The system.int32 class (or simply [int] in powershell) has a method available called "TryParse" which will not only pass back a boolean indicating whether the string is an integer, but will also return the value of the integer into an existing variable by reference if it returns true.

Example:

[string]$convertedInt = "1500"
[int]$returnedInt = 0
[bool]$result = [int]::TryParse($convertedInt, [ref]$returnedInt)

I hope this addresses the issue you initially brought up in your question.

I've gone back and tested and re-tested this, it appears that the only way I can get it to work (since I have some files in the img folder and some in js/css, etc...) is not to use a relative path to my image in the html and have everything referenced to the bundle folder. What a shame :(.

<img src="myimage.png" />

The open SPF wizard from the previous answer is no longer available, neither the one from Microsoft.

As can be seen in this link on their site (http://james.newtonking.com/archive/2009/10/23/efficient-json-with-json-net-reducing-serialized-json-size.aspx) I support using [Default()] to specify default values

Taken from the link

   public class Invoice
{
  public string Company { get; set; }
  public decimal Amount { get; set; }

  // false is default value of bool
  public bool Paid { get; set; }
  // null is default value of nullable
  public DateTime? PaidDate { get; set; }

  // customize default values
  [DefaultValue(30)]
  public int FollowUpDays { get; set; }
  [DefaultValue("")]
  public string FollowUpEmailAddress { get; set; }
}


Invoice invoice = new Invoice
{
  Company = "Acme Ltd.",
  Amount = 50.0m,
  Paid = false,
  FollowUpDays = 30,
  FollowUpEmailAddress = string.Empty,
  PaidDate = null
};

string included = JsonConvert.SerializeObject(invoice,
  Formatting.Indented,
  new JsonSerializerSettings { });

// {
//   "Company": "Acme Ltd.",
//   "Amount": 50.0,
//   "Paid": false,
//   "PaidDate": null,
//   "FollowUpDays": 30,
//   "FollowUpEmailAddress": ""
// }

string ignored = JsonConvert.SerializeObject(invoice,
  Formatting.Indented,
  new JsonSerializerSettings { DefaultValueHandling = DefaultValueHandling.Ignore });

// {
//   "Company": "Acme Ltd.",
//   "Amount": 50.0
// }

The problem is that omega in your case is matrix of dimensions 1 * 1. You should convert it to a vector if you wish to multiply t(X) %*% X by a scalar (that is omega)

In particular, you'll have to replace this line:

omega   = rgamma(1,a0,1) / L0

with:

omega   = as.vector(rgamma(1,a0,1) / L0)

everywhere in your code. It happens in two places (once inside the loop and once outside). You can substitute as.vector(.) or c(t(.)). Both are equivalent.

Here's the modified code that should work:

gibbs = function(data, m01 = 0, m02 = 0, k01 = 0.1, k02 = 0.1, 
                     a0 = 0.1, L0 = 0.1, nburn = 0, ndraw = 5000) {
    m0      = c(m01, m02) 
    C0      = matrix(nrow = 2, ncol = 2) 
    C0[1,1] = 1 / k01 
    C0[1,2] = 0 
    C0[2,1] = 0 
    C0[2,2] = 1 / k02 
    beta    = mvrnorm(1,m0,C0) 
    omega   = as.vector(rgamma(1,a0,1) / L0)
    draws   = matrix(ncol = 3,nrow = ndraw) 
    it      = -nburn 

    while (it < ndraw) {
        it    = it + 1 
        C1    = solve(solve(C0) + omega * t(X) %*% X) 
        m1    = C1 %*% (solve(C0) %*% m0 + omega * t(X) %*% y)
        beta  = mvrnorm(1, m1, C1) 
        a1    = a0 + n / 2 
        L1    = L0 + t(y - X %*% beta) %*% (y - X %*% beta) / 2 
        omega = as.vector(rgamma(1, a1, 1) / L1)
        if (it > 0) { 
            draws[it,1] = beta[1]
            draws[it,2] = beta[2]
            draws[it,3] = omega
        }
    }
    return(draws)

I think the answers here are great, but I would like to add a scenario.

Several times I've wanted to take a certain amount of characters off the front of a string, without worrying about it's length. There are several ways of doing this with RIGHT() and SUBSTRING(), but they all need to know the length of the string which can sometimes slow things down.

I've use the STUFF() function instead:

SET @Result = STUFF(@Result, 1, @LengthToRemove, '')

This replaces the length of unneeded string with an empty string.

I have used componentDidUpdate() in highchart.

Here is a simple example of this component.

import React, { PropTypes, Component } from 'react';
window.Highcharts = require('highcharts');

export default class Chartline extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      chart: ''
    };
  }

  public componentDidUpdate() {
    // console.log(this.props.candidate, 'this.props.candidate')
    if (this.props.category) {
      const category = this.props.category ? this.props.category : {};
      console.log('category', category);
      window.Highcharts.chart('jobcontainer_' + category._id, {
        title: {
          text: ''
        },
        plotOptions: {
          series: {
            cursor: 'pointer'
          }
        },
        chart: {
          defaultSeriesType: 'spline'
        },
        xAxis: {
          // categories: candidate.dateArr,
          categories: ['Day1', 'Day2', 'Day3', 'Day4', 'Day5', 'Day6', 'Day7'],
          showEmpty: true
        },
        labels: {
          style: {
            color: 'white',
            fontSize: '25px',
            fontFamily: 'SF UI Text'
          }
        },
        series: [
          {
            name: 'Low',
            color: '#9B260A',
            data: category.lowcount
          },
          {
            name: 'High',
            color: '#0E5AAB',
            data: category.highcount
          },
          {
            name: 'Average',
            color: '#12B499',
            data: category.averagecount
          }
        ]
      });
    }
  }
  public render() {
    const category = this.props.category ? this.props.category : {};
    console.log('render category', category);
    return <div id={'jobcontainer_' + category._id} style={{ maxWidth: '400px', height: '180px' }} />;
  }
}

If you need to update the value in a particular table:

UPDATE TABLE-NAME SET COLUMN-NAME = REPLACE(TABLE-NAME.COLUMN-NAME, 'STRING-TO-REPLACE', 'REPLACEMENT-STRING');

where

  TABLE-NAME         - The name of the table being updated
  COLUMN-NAME        - The name of the column being updated
  STRING-TO-REPLACE  - The value to replace
  REPLACEMENT-STRING - The replacement

V=`php -v | sed -e '/^PHP/!d' -e 's/.* \([0-9]\+\.[0-9]\+\).*$/\1/'` \
sudo apt-get install php$V-zip

In case you happen to be using Spring framework along with java, there is an easy way around.

1. Import the following.

   import org.springframework.util.Base64Utils;

2. Convert like this.

   byte[] bytearr ={0,1,2,3,4};
   String encodedText = Base64Utils.encodeToString(bytearr);
   

   To decode you can use the decodeToString method of the Base64Utils class.

Another answer, using sequential executor nsynjs:

function getExample(){

  var response1 = returnPromise1().data;

  // promise1 is resolved at this point, '.data' has the result from resolve(result)

  var response2 = returnPromise2().data;

  // promise2 is resolved at this point, '.data' has the result from resolve(result)

  console.log(response, response2);

}

nynjs.run(getExample,{},function(){
    console.log('all done');
})

Update: added working example

function synchronousCode() {_x000D_
     var urls=[_x000D_

You can use std::nextafter with a fixed factor of the epsilon of a value like the following:

bool isNearlyEqual(double a, double b)
{
  int factor = /* a fixed factor of epsilon */;

  double min_a = a - (a - std::nextafter(a, std::numeric_limits<double>::lowest())) * factor;
  double max_a = a + (std::nextafter(a, std::numeric_limits<double>::max()) - a) * factor;

  return min_a <= b && max_a >= b;
}

Below is my Script which show/hide table row with id "agencyrow".

<script type="text/javascript">

                        function showhiderow() {
                            if (document.getElementById("<%=RadioButton1.ClientID %>").checked == true) {

                                document.getElementById("agencyrow").style.display = '';
                            } else {

                                document.getElementById("agencyrow").style.display = 'none';
                            }


                        }
    </script> 

Just call function showhiderow()upon radiobutton onClick event

If you hit git stash when you have changes in the working copy (not in the staging area), git will create a stashed object and pushes onto the stack of stashes (just like you did git checkout -- . but you won't lose changes). Later, you can pop from the top of the stack.

You can use the curses.h library in linux as mentioned in the other answer.

You can install it in Ubuntu by:

sudo apt-get update

sudo apt-get install ncurses-dev

I took the installation part from here.

For me, in addition to selecting the jar - selenium-java-2.45.0.jar, I had to select all the jars in the "libs" folder under selenium root folder.

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

def player(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over: 
        computer(game_over)  #We are only going to do this if check_winner comes back as False

def check_winner(): 
    check something
    #here needs to be an if / then statement deciding if the game is over, return True if over, false if not
    if score == 100:
        return True
    else:
        return False

def computer(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over:
        player(game_over) #We are only going to do this if check_winner comes back as False

game_over = False   #We need a variable to hold wether the game is over or not, we'll start it out being false.
player(game_over)   #Start your loops, sending in the status of game_over

Above is a pretty simple example... I made up a statement for check_winner using score = 100 to denote the game being over.

You will want to use similar method of passing score into check_winner, using game_over = check_winner(score). Then you can create a score at the beginning of your program and pass it through to computer and player just like game_over is being handled.

Since you have a DataTable already, and since I am assuming you are using SQL Server 2008 or better, this is probably the most straightforward way. First, in your database, create the following two objects:

CREATE TYPE dbo.MyDataTable -- you can be more speciifc here
AS TABLE
(
  col1 INT,
  col2 DATETIME
  -- etc etc. The columns you have in your data table.
);
GO

CREATE PROCEDURE dbo.InsertMyDataTable
  @dt AS dbo.MyDataTable READONLY
AS
BEGIN
  SET NOCOUNT ON;

  INSERT dbo.RealTable(column list) SELECT column list FROM @dt;
END
GO

Now in your C# code:

DataTable tvp = new DataTable();
// define / populate DataTable

using (connectionObject)
{
    SqlCommand cmd = new SqlCommand("dbo.InsertMyDataTable", connectionObject);
    cmd.CommandType = CommandType.StoredProcedure;
    SqlParameter tvparam = cmd.Parameters.AddWithValue("@dt", tvp);
    tvparam.SqlDbType = SqlDbType.Structured;
    cmd.ExecuteNonQuery();
}

If you had given more specific details in your question, I would have given a more specific answer.

$msg="You Enter Wrong Username OR Password"; $responso=json_encode($msg);

echo "{\"status\" : \"400\", \"responce\" : \"603\", \"message\" : \"You Enter Wrong Username OR Password\", \"feed\":".str_replace("<p>","",$responso). "}";

Open Task Manager and find service adb.exe after saw those service just end it, and run again

Cache.delete() can be used for new chrome, firefox and opera.

I had the same issue. When compared the java version mentioned in the pom.xml file is different and the JAVA_HOME env variable was pointing to different version of jdk.

Have the JAVA_HOME and pom.xml updated to the same jdk installation path

My answer comes quite late because I'm a pretty new developer. This is what you can do:

Location.select(:name, :website, :city).find(row.id)

Btw, this is Rails 4

I'm not 100% sure what your sample code is supposed to do, but the following snippet should help you 'call the contacts list function, pick a contact, then return to [your] app with the contact's name'.

There are three steps to this process.

1. Permissions

Add a permission to read contacts data to your application manifest.

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

2. Calling the Contact Picker

Within your Activity, create an Intent that asks the system to find an Activity that can perform a PICK action from the items in the Contacts URI.

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

Call startActivityForResult, passing in this Intent (and a request code integer, PICK_CONTACT in this example). This will cause Android to launch an Activity that's registered to support ACTION_PICK on the People.CONTENT_URI, then return to this Activity when the selection is made (or canceled).

startActivityForResult(intent, PICK_CONTACT);

3. Listening for the Result

Also in your Activity, override the onActivityResult method to listen for the return from the 'select a contact' Activity you launched in step 2. You should check that the returned request code matches the value you're expecting, and that the result code is RESULT_OK.

You can get the URI of the selected contact by calling getData() on the data Intent parameter. To get the name of the selected contact you need to use that URI to create a new query and extract the name from the returned cursor.

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);

  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  getContentResolver().query(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          // TODO Whatever you want to do with the selected contact name.
        }
      }
      break;
  }
}

Just one more idea to detect:

DebugMode.h

#import <Foundation/Foundation.h>

@interface DebugMode: NSObject
    +(BOOL) isDebug;
@end

DebugMode.m

#import "DebugMode.h"

@implementation DebugMode
+(BOOL) isDebug {
#ifdef DEBUG
    return true;
#else
    return false;
#endif
}
@end

add into header bridge file:

#include "DebugMode.h"

usage:

DebugMode.isDebug()

It is not needed to write something inside project properties swift flags.

You could do this but it is hacky

.application-title {
   background:url("/path/to/image.png");
   /* set these dims according to your image size */
   width:500px;
   height:500px;
}

.application-title img {
   display:none;
}

Here is a working example:

Pay close attention to the first part of the error: "variable is not declared"

Ignore the second part: "it may be inaccessible due to its protection level". It's a red herring.

Some questions... (the answers might be in that image you posted, but I can't seem to make it larger and my eyes don't read that small of print... Any chance you can post the code in a way these older eyes can read it? Makes it hard to know the total picture. In particular I am suspicious of your Page directives.)

We know that 1stReasonTypes is a listbox, but for some reason it seems like we don't know WHICH listbox. This is why I want to see your page directives.

But also, how are you calling the private method FormRefresh()? It's not an event handler, which makes me wonder if you are trying to reference a listbox in a form that is not handled properly in this code behind.

You may need to find the control 1stReasonTypes. Try maybe putting your listbox inside something like

<div id="MyFormDiv" runat="server">.....</div>

then in FormRefresh(), do a...

Dim 1stReasonTypesNew As listbox = MyFormDiv.FindControl("1stReasonTypes")

Or use an existing control, object, or page instead of a div. More info on FindControl: http://msdn.microsoft.com/en-us/library/486wc64h(v=vs.110).aspx

But no matter how you slice it, there is something funky going here such that 1stReasonTypes doesn't know which exact listbox it's supposed to be.

I needed to find a way to do this too, using numbers from different places and not in a collection. I was sure there was a method to do this in c#...though by the looks of it I'm muddling my languages...

Anyway, I ended up writing a couple of generic methods to do it...

    static T Max<T>(params T[] numberItems)
    {
        return numberItems.Max();
    }

    static T Min<T>(params T[] numberItems)
    {
        return numberItems.Min();
    }

...call them this way...

    int intTest = Max(1, 2, 3, 4);
    float floatTest = Min(0f, 255.3f, 12f, -1.2f);

use CHAR(10) for New Line in SQL
char(9) for Tab
and Char(13) for Carriage Return

You can use @BeforeClass annotation to assure that setup() is always called first. Similarly, you can use @AfterClass annotation to assure that tearDown() is always called last.

This is usually not recommended, but it is supported.

It's not exactly what you want - but it'll essentially keep your DB connection open the entire time your tests are running, and then close it once and for all at the end.

I have found one solution to this problem.

Please follow below these steps:

1. Go to File->Settings->Compiler->add To --stacktrace --debug in Command-line-Options box and then apply & ok.
2. Rebuild a project.
3. Run a project.

I found that here the case with enum values that have EnumMember value was not considered. So here we go:

using System.Runtime.Serialization;

public static TEnum ToEnum<TEnum>(this string value, TEnum defaultValue) where TEnum : struct
{
    if (string.IsNullOrEmpty(value))
    {
        return defaultValue;
    }

    TEnum result;
    var enumType = typeof(TEnum);
    foreach (var enumName in Enum.GetNames(enumType))
    {
        var fieldInfo = enumType.GetField(enumName);
        var enumMemberAttribute = ((EnumMemberAttribute[]) fieldInfo.GetCustomAttributes(typeof(EnumMemberAttribute), true)).FirstOrDefault();
        if (enumMemberAttribute?.Value == value)
        {
            return Enum.TryParse(enumName, true, out result) ? result : defaultValue;
        }
    }

    return Enum.TryParse(value, true, out result) ? result : defaultValue;
}

And example of that enum:

public enum OracleInstanceStatus
{
    Unknown = -1,
    Started = 1,
    Mounted = 2,
    Open = 3,
    [EnumMember(Value = "OPEN MIGRATE")]
    OpenMigrate = 4
}

If not finding it is an exceptional event (i.e. it should be there under normal circumstances), then throw. Otherwise, return a "not found" value (can be null, but does not have to), or even have the method return a boolean for found/notfound and an out parameter for the actual object.

The trouble looks like the image isn't square and the browser adjusts as such. After rotation ensure the dimensions are retained by changing the image margin.

.imagetest img {
  transform: rotate(270deg);
  ...
  margin: 10px 0px;
}

The amount will depend on the difference in height x width of the image. You may also need to add display:inline-block; or display:block to get it to recognize the margin parameter.

#include <thread>
#include <iostream>

class bar {
public:
  void foo() {
    std::cout << "hello from member function" << std::endl;
  }
};

int main()
{
  std::thread t(&bar::foo, bar());
  t.join();
}

EDIT: Accounting your edit, you have to do it like this:

  std::thread spawn() {
    return std::thread(&blub::test, this);
  }

UPDATE: I want to explain some more points, some of them have also been discussed in the comments.

The syntax described above is defined in terms of the INVOKE definition (§20.8.2.1):

Define INVOKE (f, t1, t2, ..., tN) as follows:

• (t1.*f)(t2, ..., tN) when f is a pointer to a member function of a class T and t1 is an object of type T or a reference to an object of type T or a reference to an object of a type derived from T;
• ((*t1).*f)(t2, ..., tN) when f is a pointer to a member function of a class T and t1 is not one of the types described in the previous item;
• t1.*f when N == 1 and f is a pointer to member data of a class T and t 1 is an object of type T or a
  reference to an object of type T or a reference to an object of a
  type derived from T;
• (*t1).*f when N == 1 and f is a pointer to member data of a class T and t 1 is not one of the types described in the previous item;
• f(t1, t2, ..., tN) in all other cases.

Another general fact which I want to point out is that by default the thread constructor will copy all arguments passed to it. The reason for this is that the arguments may need to outlive the calling thread, copying the arguments guarantees that. Instead, if you want to really pass a reference, you can use a std::reference_wrapper created by std::ref.

std::thread (foo, std::ref(arg1));

By doing this, you are promising that you will take care of guaranteeing that the arguments will still exist when the thread operates on them.

Note that all the things mentioned above can also be applied to std::async and std::bind.

You could also use a LEFT JOIN and IS NULL condition:

SELECT 
  mac, 
  creation_date 
FROM 
  logs
    LEFT JOIN consols ON logs.mac = consols.mac
WHERE 
  logs_type_id=11
AND
  consols.mac IS NULL;

An index on the "mac" columns might improve performance.

You can simply kill docker cli process by sending SEGKILL. If you started the container with

docker run -it some/container

You can get it's pid

ps -aux | grep docker

user   1234  0.3  0.6 1357948 54684 pts/2   Sl+  15:09   0:00 docker run -it some/container

let's say it's 1234, you can "detach" it with

kill -9 1234

It's somewhat of a hack but it works!

Summary (@Freek Wiekmeijer, @gtalarico) other's answer:

Logic of Login

• Many resource(pages, api) need authentication, then can access, otherwise 405 Not Allowed
• Common authentication=grant access method are:
  • cookie
  • auth header
    • Basic xxx
    • Authorization xxx

How use cookie in requests to auth

1. first get/generate cookie
2. send cookie for following request

• manual set cookie in headers
• auto process cookie by requests's
  • session to auto manage cookies
  • response.cookies to manually set cookies

use requests's session auto manage cookies

curSession = requests.Session() 
# all cookies received will be stored in the session object

payload={'username': "yourName",'password': "yourPassword"}
curSession.post(firstUrl, data=payload)
# internally return your expected cookies, can use for following auth

# internally use previously generated cookies, can access the resources
curSession.get(secondUrl)

curSession.get(thirdUrl)

manually control requests's response.cookies

payload={'username': "yourName",'password': "yourPassword"}
resp1 = requests.post(firstUrl, data=payload)

# manually pass previously returned cookies into following request
resp2 = requests.get(secondUrl, cookies= resp1.cookies)

resp3 = requests.get(thirdUrl, cookies= resp2.cookies)

These 2 methods I tried are not working:

1. Use npm

sudo npm cache clean -f

sudo npm install -g n

sudo n stable

2. Manual install node from official website (https://nodejs.org/en/)

After trying, node -v still shows the old version of node.

Below method works for me:

Step 1: Install nvm (for more details: https://github.com/creationix/nvm#installation)

Open terminal and type this command:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

Close terminal and reopen it.

Type this command to check if nvm is installed:

command -v nvm

Step 2: To download, compile, and install the latest release of node, type this:

nvm install node ("node" is an alias for the latest version)

To check if node gets the latest version (v10.11.0).

Installing the latest node also installs the latest npm.

Check if npm gets the latest version (6.4.1).

  $("#customFile").change(function() { 
    var fileName = $("#customFile").val();  

    if(fileName) { // returns true if the string is not empty   
        $('.picture-selected').addClass('disable-inputs'); 
        $('#btn').removeClass('disabled');   
    } else { // no file was selected 
      $('.picture-selected').removeClass('disable-inputs'); 
      $('#btn').addClass('disabled');
    }  
  });

Here is another possible hack not using js and still using css content. Note that as :after is not supported on some browser for inputs, we need to select the input in another way, same for content attr('')

input[type=date]:invalid+span:after {_x000D_
  content:"Birthday";_x000D_
  position:absolute;_x000D_
  left:0;_x000D_
  top:0;_x000D_
}_x000D_
_x000D_
input[type=date]:focus:invalid+span:after {_x000D_
  display:none;_x000D_
}_x000D_
_x000D_
input:not(:focus):invalid {_x000D_
  color:transparent;_x000D_
}_x000D_
_x000D_
label.wrapper {_x000D_
 position:relative;_x000D_
}

<label class="wrapper">_x000D_
 <input_x000D_
    type="date"_x000D_
     required="required" _x000D_
 />_x000D_
 <span></span>_x000D_
</label>

preg_replace('#[^\w()/.%\-&]#',"",$string);

Quick note if you don't have an .aspx in your project (i.e. its XBAP) but you still need to debug using IE, just add a htm page to your project and right click on that to set the default. It's hacky, but it works :P

This is the problem to start with:

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("EST"));

The 3-letter abbreviations should be wholeheartedly avoided in favour of TZDB zone IDs. EST is Eastern Standard Time - and Standard time never observes DST; it's not really a full time zone name. It's the name used for part of a time zone. (Unfortunately I haven't come across a good term for this "half time zone" concept.)

You want a full time zone name. For example, America/New_York is in the Eastern time zone:

TimeZone zone = TimeZone.getTimeZone("America/New_York");
DateFormat format = DateFormat.getDateTimeInstance();
format.setTimeZone(zone);

System.out.println(format.format(new Date()));

Adding to what @Shog9 posted, you can also restrict dates individually in the beforeShowDay: callback function.

You supply a function that takes a date and returns a boolean array:

"$(".selector").datepicker({ beforeShowDay: nationalDays}) 
natDays = [[1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'], 
[5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7, 
'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']]; 
function nationalDays(date) { 
    for (i = 0; i < natDays.length; i++) { 
      if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == 
natDays[i][1]) { 
        return [false, natDays[i][2] + '_day']; 
      } 
    } 
  return [true, '']; 
} 

Simply get date and convert

Declare @Date as Date =Getdate()

Select Format(@Date,'dd/MM/yyyy') as [dd/MM/yyyy] // output: 22/10/2020
Select Format(@Date,'dd-MM-yyyy') as [dd-MM-yyyy] // output: 22-10-2020

//string date
Select Format(cast('25/jun/2013' as date),'dd/MM/yyyy') as StringtoDate // output: 25/06/2013

The layout is extremely inefficient and bloated. You don't need that many LinearLayouts. In fact you don't need any LinearLayout at all.

Use only one RelativeLayout. Like this.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageButton android:background="@null"
        android:id="@+id/back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/back"
        android:padding="10dip"
        android:layout_alignParentLeft="true"/>
    <ImageButton android:background="@null"
        android:id="@+id/forward"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/forward"
        android:padding="10dip"
        android:layout_toRightOf="@id/back"/>
    <ImageButton android:background="@null"
        android:id="@+id/special"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/barcode"
        android:padding="10dip"
        android:layout_alignParentRight="true"/>
</RelativeLayout>

Complete solution:

import contextlib
import subprocess

# Unix, Windows and old Macintosh end-of-line
newlines = ['\n', '\r\n', '\r']
def unbuffered(proc, stream='stdout'):
    stream = getattr(proc, stream)
    with contextlib.closing(stream):
        while True:
            out = []
            last = stream.read(1)
            # Don't loop forever
            if last == '' and proc.poll() is not None:
                break
            while last not in newlines:
                # Don't loop forever
                if last == '' and proc.poll() is not None:
                    break
                out.append(last)
                last = stream.read(1)
            out = ''.join(out)
            yield out

def example():
    cmd = ['ls', '-l', '/']
    proc = subprocess.Popen(
        cmd,
        stdout=subprocess.PIPE,
        stderr=subprocess.STDOUT,
        # Make all end-of-lines '\n'
        universal_newlines=True,
    )
    for line in unbuffered(proc):
        print line

The object doesn't have 30 properties. It has one, which is an array that has 30 elements. You need the number of elements in that array.

That's a rather large question.

LDAP is a protocol for accessing a directory. A directory contains objects; generally those related to users, groups, computers, printers and so on; company structure information (although frankly you can extend it and store anything in there).

LDAP gives you query methods to add, update and remove objects within a directory (and a bunch more, but those are the central ones).

What LDAP does not do is provide a database; a database provides LDAP access to itself, not the other way around. It is much more than signup.
