Try this one. It will sort numbers from other variables.

const obj = {
   a: 1,
   b: 2,
   c: 3
};
const result = Object.keys(obj)
.reduce((acc, rec) => typeof obj[rec] === "number" ? acc.concat([obj[rec]]) : acc, [])
.reduce((acc, rec) => acc + rec)

From angular's documentation,

ng-init SHOULD NOT be used for any initialization. It should be used only for aliasing. https://docs.angularjs.org/api/ng/directive/ngInit

onload should be used if any expression needs to be evaluated after a partial view is loaded (by ng-include). https://docs.angularjs.org/api/ng/directive/ngInclude

The major difference between them is when used with ng-include.

<div ng-include="partialViewUrl" onload="myFunction()"></div>

In this case, myFunction is called everytime the partial view is loaded.

<div ng-include="partialViewUrl" ng-init="myFunction()"></div>

Whereas, in this case, myFunction is called only once when the parent view is loaded.

Also lazy is useful without cyclic dependencies, as in the following code:

abstract class X {
  val x: String
  println ("x is "+x.length)
}

object Y extends X { val x = "Hello" }
Y

Accessing Y will now throw null pointer exception, because x is not yet initialized. The following, however, works fine:

abstract class X {
  val x: String
  println ("x is "+x.length)
}

object Y extends X { lazy val x = "Hello" }
Y

EDIT: the following will also work:

object Y extends { val x = "Hello" } with X 

This is called an "early initializer". See this SO question for more details.

I'm pretty sure it's similar to Laravel template, this is how I did mine.

Another option to stream images from a webcam to a browser is via mjpeg. This is just a series of jpeg images that most modern browsers support as part of the tag. Here's a sample server written in c#:

https://www.codeproject.com/articles/371955/motion-jpeg-streaming-server

This works well over a LAN, but not as well over the internet as mjpeg is not as effcient as other video codecs (h264, VP8 etc..)

We started finding some machines with IE 11 not playing video (via flash) after we set the emulation mode of our app (web browser control) to 110001. Adding the meta tag to our htm files worked for us.

-> is used to call a method, or access a property, on the object of a class

=> is used to assign values to the keys of an array

E.g.:

    $ages = array("Peter"=>32, "Quagmire"=>30, "Joe"=>34, 1=>2); 

And since PHP 7.4+ the operator => is used too for the added arrow functions, a more concise syntax for anonymous functions.

Try this instead:

SUM(CASE WHEN ValueDate > @startMonthDate THEN cash ELSE 0 END)

Explanation

Your CASE expression has incorrect syntax. It seems you are confusing the simple CASE expression syntax with the searched CASE expression syntax. See the documentation for CASE:

The CASE expression has two formats:

• The simple CASE expression compares an expression to a set of simple expressions to determine the result.
• The searched CASE expression evaluates a set of Boolean expressions to determine the result.

You want the searched CASE expression syntax:

CASE
     WHEN Boolean_expression THEN result_expression [ ...n ] 
     [ ELSE else_result_expression ] 
END

As a side note, if performance is an issue you may find that this expression runs more quickly if you rewrite using a JOIN and GROUP BY instead of using a dependent subquery.

This is a very old question, but my answer may help someone.

• In the encrypt method, don't forget to encode your string to Base64
• In the decrypt method, don't forget to decode your string to Base64

Below is the working code

    import java.util.Arrays;
    import java.util.Base64;

    import javax.crypto.Cipher;
    import javax.crypto.SecretKey;
    import javax.crypto.spec.SecretKeySpec;

    public class EncryptionDecryptionUtil {

    public static String encrypt(final String secret, final String data) {


        byte[] decodedKey = Base64.getDecoder().decode(secret);

        try {
            Cipher cipher = Cipher.getInstance("AES");
            // rebuild key using SecretKeySpec
            SecretKey originalKey = new SecretKeySpec(Arrays.copyOf(decodedKey, 16), "AES");
            cipher.init(Cipher.ENCRYPT_MODE, originalKey);
            byte[] cipherText = cipher.doFinal(data.getBytes("UTF-8"));
            return Base64.getEncoder().encodeToString(cipherText);
        } catch (Exception e) {
            throw new RuntimeException(
                    "Error occured while encrypting data", e);
        }

    }

    public static String decrypt(final String secret,
            final String encryptedString) {


        byte[] decodedKey = Base64.getDecoder().decode(secret);

        try {
            Cipher cipher = Cipher.getInstance("AES");
            // rebuild key using SecretKeySpec
            SecretKey originalKey = new SecretKeySpec(Arrays.copyOf(decodedKey, 16), "AES");
            cipher.init(Cipher.DECRYPT_MODE, originalKey);
            byte[] cipherText = cipher.doFinal(Base64.getDecoder().decode(encryptedString));
            return new String(cipherText);
        } catch (Exception e) {
            throw new RuntimeException(
                    "Error occured while decrypting data", e);
        }
    }


    public static void main(String[] args) {

        String data = "This is not easy as you think";
        String key = "---------------------------------";
        String encrypted = encrypt(key, data);
        System.out.println(encrypted);
        System.out.println(decrypt(key, encrypted));
      }
  }

For Generating Key you can use below class

    import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.util.Base64;

import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;

public class SecretKeyGenerator {

    public static void main(String[] args) throws NoSuchAlgorithmException {

        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");

        SecureRandom secureRandom = new SecureRandom();
        int keyBitSize = 256;
        keyGenerator.init(keyBitSize, secureRandom);

        SecretKey secretKey = keyGenerator.generateKey();

 System.out.println(Base64.getEncoder().encodeToString(secretKey.getEncoded()));
    }

}

You can change your PrintWriter and use method getAbsoluteFile(), this function returns the absolute File object of the given abstract pathname.

PrintWriter out = new PrintWriter(new FileWriter(log.getAbsoluteFile(), true));

Improving on YellowApple's answer:

This is a Bash function to capture stderr into any variable

stderr_capture_example.sh:

#!/usr/bin/env bash

# Capture stderr from a command to a variable while maintaining stdout
# @Args:
# $1: The variable name to store the stderr output
# $2: Vararg command and arguments
# @Return:
# The Command's Returnn-Code or 2 if missing arguments
function capture_stderr {
  [ $# -lt 2 ] && return 2
  local stderr="$1"
  shift
  {
    printf -v "$stderr" '%s' "$({ "$@" 1>&3; } 2>&1)"
  } 3>&1
}

# Testing with a call to erroring ls
LANG=C capture_stderr my_stderr ls "$0" ''

printf '\nmy_stderr contains:\n%s' "$my_stderr"

Testing:

bash stderr_capture_example.sh

Output:

 stderr_capture_example.sh

my_stderr contains:
ls: cannot access '': No such file or directory

This function can be used to capture the returned choice of a dialog command.

I threw together a small library for this since I do think there are valid use cases for manipulating stylesheets in JS. Reasons being:

• Setting styles that must be calculated or retrieved - for example setting the user's preferred font-size from a cookie.
• Setting behavioural (not aesthetic) styles, especially for UI widget/plugin developers. Tabs, carousels, etc, often require some basic CSS simply to function - shouldn't demand a stylesheet for the core function.
• Better than inline styles since CSS rules apply to all current and future elements, and don't clutter the HTML when viewing in Firebug / Developer Tools.

subset() is also useful:

subset(DATAFRAME, COLUMNNAME == "")

For a survey package, maybe the survey package is pertinent?

Karl answered your search-path question, but as far as the "source of the files" goes, one thing to be aware of is that if you install the libfoo package and want to do some development with it (i.e., use its headers), you will also need to install libfoo-dev. The standard library header files are already in /usr/include, as you saw.

Note that some libraries with a lot of headers will install them to a subdirectory, e.g., /usr/include/openssl. To include one of those, just provide the path without the /usr/include part, for example:

#include <openssl/aes.h>

If your page really relies on the fact that people won't be able to see that menu, you should know that modern browsers (for example Firefox) let the user decide if he really wants to disable it or not. So you have no guarantee at all that the menu would be really disabled.

You can reset the plot by doing this:

dev.off()

Here is my version to find mount points of a docker compose. In use this to backup the volumes.

 # for Id in $(docker-compose -f ~/ida/ida.yml ps -q); do docker inspect -f '{{ (index .Mounts 0).Source }}' $Id; done
/data/volumes/ida_odoo-db-data/_data
/data/volumes/ida_odoo-web-data/_data

This is a combination of previous solutions.

(Taken from my comment)

pip won't handle system level dependencies. You'll have to apt-get install libfreetype6-dev before continuing. (It even says so right in your output. Try skimming over it for such errors next time, usually build outputs are very detailed)

If you're getting error TS1005: 'finally' expected., it means you forgot to implement catch after try. Generally, it means the syntax you attempted to use was incorrect.

I came here looking for how to delete empty __init__.py files as they are implicit in Python 3.3+ and ended up using:

find -depth '(' -type f  -name __init__.py ')' -print0 |
  while IFS= read -d '' -r file; do if [[ ! -s $file ]]; then rm $file; fi; done

Also (at least in zsh) using $path as the variable also breaks your $PATH env and so it'll break your open shell. Anyway, thought I'd share!

java.time

I am providing the modern answer. The Timestamp class was always poorly designed, a real hack on top of the already poorly designed Date class. Both those classes are now long outdated. Don’t use them.

When the question was asked, you would need a Timestamp for sending a point in time to the SQL database. Since JDBC 4.2 that is no longer the case. Assuming your database needs a timestamp with time zone (recommended for true timestamps), pass it an OffsetDateTime.

Before we can do that we need to overcome a real trouble with your sample string, Mon May 27 11:46:15 IST 2013: the time zone abbreviation. IST may mean Irish Summer Time, Israel Standard Time or India Standard Time (I have even read that Java may parse it into Atlantic/Reykjavik time zone — Icelandic Standard Time?) To control the interpretation we pass our preferred time zone to the formatter that we are using for parsing.

    DateTimeFormatter formatter = new DateTimeFormatterBuilder()
            .appendPattern("EEE MMM dd HH:mm:ss ")
            .appendZoneText(TextStyle.SHORT, Set.of(ZoneId.of("Asia/Kolkata")))
            .appendPattern(" yyyy")
            .toFormatter(Locale.ROOT);
    String dateString = "Mon May 27 11:46:15 IST 2013";
    OffsetDateTime dateTime = formatter.parse(dateString, Instant::from)
            .atOffset(ZoneOffset.UTC);
    System.out.println(dateTime);

This snippet prints:

2013-05-27T06:16:15Z

This is the UTC equivalent of your string (assuming IST was for India Standard Time). Pass the OffsetDateTime to your database using one of the PreparedStatement.setObject methods (not setTimestamp).

How can I convert this into timestamp and calculate in seconds the difference between the same and current time?

Calculating the difference in seconds goes very naturally with java.time:

    long differenceInSeconds = ChronoUnit.SECONDS
            .between(dateTime, OffsetDateTime.now(ZoneOffset.UTC));
    System.out.println(differenceInSeconds);

When running just now I got:

202213260

Link: Oracle tutorial: Date Time explaining how to use java.time.

The answers so far have covered the details, but if you don't intend to drop down to assembly, then all you have to know is that both the caller and the callee must use the same calling convention, otherwise you'll get bugs that are hard to find.

<input type="text" name="time" data-provide="timepicker"  id="time" class="form-control" placeholder="Start Time" value="" />


$('#time').timepicker({
        timeFormat: 'H:i',
        'scrollDefaultNow'      : 'true',
        'closeOnWindowScroll'   : 'true',
        'showDuration'          : false,
        'ignoreReadonly'        : true,

})

work for me.

Yes.

If the scrollbar is not the browser scrollbar, then it will be built of regular HTML elements (probably divs and spans) and can thus be styled (or will be Flash, Java, etc and can be customized as per those environments).

The specifics depend on the DOM structure used.

Rewriting a file in place is often done by saving the old copy with a modified name. Unix folks add a ~ to mark the old one. Windows folks do all kinds of things -- add .bak or .old -- or rename the file entirely or put the ~ on the front of the name.

import shutil
shutil.move( afile, afile+"~" )

destination= open( aFile, "w" )
source= open( aFile+"~", "r" )
for line in source:
    destination.write( line )
    if <some condition>:
        destination.write( >some additional line> + "\n" )
source.close()
destination.close()

Instead of shutil, you can use the following.

import os
os.rename( aFile, aFile+"~" )

The above answers are too complex.

.class:first-of-type { }

This will select the first-type of class. MDN Source

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

In the end all it took was reinstalling Pillow:

Checkout the .SaveAs() method in Excel object.

wbWorkbook.SaveAs("c:\yourdesiredFilename.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSV)

Or following:

    Microsoft.Office.Interop.Excel.Workbook wbWorkbook = app.Workbooks.Add(Type.Missing);

    Microsoft.Office.Interop.Excel.Worksheet CurSheet = (Microsoft.Office.Interop.Excel.Worksheet)wsSheet[1];

    Microsoft.Office.Interop.Excel.Range thisCell = (Microsoft.Office.Interop.Excel.Range)CurSheet.Cells[1, 1];

    thisCell.Value2 = "This is a test.";

    wbWorkbook.SaveAs(@"c:\one.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

Of course there is a best way.Objects in javascript have enumerable and nonenumerable properties.

var empty = {};
console.log(empty.toString);
// . function toString(){...}
console.log(empty.toString());
// . [object Object]

In the example above you can see that an empty object actually has properties.

Ok first let's see which is the best way:

var new_object = Object.create(null)

new_object.name = 'Roland'
new_object.last_name = 'Doda'
//etc

console.log("toString" in new_object) //=> false

In the example above the log will output false.

Now let's see why the other object creation ways are incorrect.

//Object constructor
var object = new Object();

console.log("toString" in object); //=> true

//Literal constructor
var person = { 
  name : "Anand",
  getName : function (){
   return this.name
  } 
} 

console.log("toString" in person); //=> true

//function Constructor
function Person(name){
  this.name = name
  this.getName = function(){
    return this.name
  } 
}

var person = new Person ('landi')

console.log("toString" in person); //=> true

//Prototype
function Person(){};

Person.prototype.name = "Anand";

console.log("toString" in person); //=> true

//Function/Prototype combination
function Person2(name){
  this.name = name;
} 

Person2.prototype.getName = function(){
  return this.name
}

var person2 = new Person2('Roland')

console.log("toString" in person2) //=> true

As you can see above,all examples log true.Which means if you have a case that you have a for in loop to see if the object has a property will lead you to wrong results probably.

Note that the best way it is not easy.You have to define all properties of object line by line.The other ways are more easier and will have less code to create an object but you have to be aware in some cases. I always use the "other ways" by the way and one solution to above warning if you don't use the best way is:

 for (var property in new_object) {
  if (new_object.hasOwnProperty(property)) {
    // ... this is an own property
  }
 }

var baseTags = document.getElementsByTagName("base");
var basePath = baseTags.length ? 
    baseTags[ 0 ].href.substr( location.origin.length, 999 ) : 
    "";

This is a solution that saves the profile directory for Firefox (similar to the user-data-dir (user data directory) in Chrome) (it involves manually copying the directory around. I haven't been able to find another way):

It was tested on Linux.

Short version:

• To save the profile

driver.execute_script("window.close()")
time.sleep(0.5)
currentProfilePath = driver.capabilities["moz:profile"]
profileStoragePath = "/tmp/abc"
shutil.copytree(currentProfilePath, profileStoragePath,
                ignore_dangling_symlinks=True
                )

• To load the profile

driver = Firefox(executable_path="geckodriver-v0.28.0-linux64",
                 firefox_profile=FirefoxProfile(profileStoragePath)
                )

Long version (with demonstration that it works and a lot of explanation -- see comments in the code)

The code uses localStorage for demonstration, but it works with cookies as well.

#initial imports

from selenium.webdriver import Firefox, FirefoxProfile

import shutil

                  # named "geckodriver" and placed in system PATH
                  # then this is not necessary
                )

# Navigate to an arbitrary page and set some local storage
driver.get("https://DuckDuckGo.com")
assert driver.execute_script(r"""{
        const tmp = localStorage.a; localStorage.a="1";
        return [tmp, localStorage.a]
    }""") == [None, "1"]

    # NOTE: It might not work if there are multiple windows!

    # Wait for a bit for the browser to clean up
    # (shutil.copytree might throw some weird error if the source directory changes while copying)
    time.sleep(0.5)

else:
    pass
    # I haven't been able to find any other, more elegant way.
    #`close()` and `quit()` both delete the profile directory

               )

driver.quit()
assert not os.path.isdir(currentProfilePath)
# Selenium cleans up properly if driver.quit() is called,
# but not necessarily if the object is destructed


# Now reopen it with the old profile

driver=Firefox(executable_path="geckodriver-v0.28.0-linux64",
               firefox_profile=FirefoxProfile(profileStoragePath)
              )

# Note that the profile directory is **copied** -- see FirefoxProfile documentation
assert driver.profile.path!=profileStoragePath
assert driver.capabilities["moz:profile"]!=profileStoragePath

# Confusingly...
assert driver.profile.path!=driver.capabilities["moz:profile"]
# And only the latter is updated.
# To save it again, use the same method as previously mentioned

# Check the data is still there

driver.get("https://DuckDuckGo.com")

data = driver.execute_script(r"""return localStorage.a""")
assert data=="1", data

driver.quit()

assert not os.path.isdir(driver.capabilities["moz:profile"])
assert not os.path.isdir(driver.profile.path)

What doesn't work:

• Initialize Firefox(capabilities={"moz:profile": "/path/to/directory"}) -- the driver will not be able to connect.
• options=Options(); options.add_argument("profile"); options.add_argument("/path/to/directory"); Firefox(options=options) -- same as above.

Column names can contain characters and reserved words that will confuse the query execution engine, so placing brackets around them at all times prevents this from happening. Easier than checking for an issue and then dealing with it, I guess.

Only "keyboard focusable" elements can be focused with .focus(). div aren't meant to be natively focusable. You have to add tabindex="0" attributes to it to achieve that. input, button, a etc... are natively focusable.

Or you might have something like this (redeclaring a variable):

var data = [];
var data = 

I discovered that FF triggers the focus event for iframe.contentWindow but not for iframe.contentWindow.document. Chrome for example can handle both cases. so, I just needed to bind my event handlers to iframe.contentWindow in order to get things working. Maybe this helps somebody ...

Basically it's just using its macro functionality, but won't work on headless setups though.

Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of robocopy can pick up where it left off rather than re-copying the entire file.

That option could be useful when copying very large files over a potentially unstable connection.

Backup mode (/B) has to do with how robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running in an Administrator context or otherwise have backup rights to use this flag.

If a type implements two interfaces, and each interface define a method that has identical signature, then in effect there is only one method, and they are not distinguishable. If, say, the two methods have conflicting return types, then it will be a compilation error. This is the general rule of inheritance, method overriding, hiding, and declarations, and applies also to possible conflicts not only between 2 inherited interface methods, but also an interface and a super class method, or even just conflicts due to type erasure of generics.

Compatibility example

Here's an example where you have an interface Gift, which has a present() method (as in, presenting gifts), and also an interface Guest, which also has a present() method (as in, the guest is present and not absent).

Presentable johnny is both a Gift and a Guest.

public class InterfaceTest {
    interface Gift  { void present(); }
    interface Guest { void present(); }

    interface Presentable extends Gift, Guest { }

    public static void main(String[] args) {
        Presentable johnny = new Presentable() {
            @Override public void present() {
                System.out.println("Heeeereee's Johnny!!!");
            }
        };
        johnny.present();                     // "Heeeereee's Johnny!!!"

        ((Gift) johnny).present();            // "Heeeereee's Johnny!!!"
        ((Guest) johnny).present();           // "Heeeereee's Johnny!!!"

        Gift johnnyAsGift = (Gift) johnny;
        johnnyAsGift.present();               // "Heeeereee's Johnny!!!"

        Guest johnnyAsGuest = (Guest) johnny;
        johnnyAsGuest.present();              // "Heeeereee's Johnny!!!"
    }
}

The above snippet compiles and runs.

Note that there is only one @Override necessary!!!. This is because Gift.present() and Guest.present() are "@Override-equivalent" (JLS 8.4.2).

Thus, johnny only has one implementation of present(), and it doesn't matter how you treat johnny, whether as a Gift or as a Guest, there is only one method to invoke.

Incompatibility example

Here's an example where the two inherited methods are NOT @Override-equivalent:

public class InterfaceTest {
    interface Gift  { void present(); }
    interface Guest { boolean present(); }

    interface Presentable extends Gift, Guest { } // DOES NOT COMPILE!!!
    // "types InterfaceTest.Guest and InterfaceTest.Gift are incompatible;
    //  both define present(), but with unrelated return types"
}

This further reiterates that inheriting members from an interface must obey the general rule of member declarations. Here we have Gift and Guest define present() with incompatible return types: one void the other boolean. For the same reason that you can't an void present() and a boolean present() in one type, this example results in a compilation error.

Summary

You can inherit methods that are @Override-equivalent, subject to the usual requirements of method overriding and hiding. Since they ARE @Override-equivalent, effectively there is only one method to implement, and thus there's nothing to distinguish/select from.

The compiler does not have to identify which method is for which interface, because once they are determined to be @Override-equivalent, they're the same method.

Resolving potential incompatibilities may be a tricky task, but that's another issue altogether.

Try printf("val = 0x%llx\n", val);. See the printf manpage:

ll (ell-ell). A following integer conversion corresponds to a long long int or unsigned long long int argument, or a following n conversion corresponds to a pointer to a long long int argument.

Use the adbwireless app to enable the phone, then use adb connect from the Windows machine to talk to it. The adbwireless app on the phone tells you how to connect to it, giving the IP address and everything.

The much less fun alternative is to connect via USB, tell the phone to use TCPIP via adb tcpip 5555, then disconnect USB, then use adb connect. This is much harder because this way you have to figure out the IP address of the phone yourself (adbwireless tells you the IP), you have to connect via USB, and you have to run adb tcpip (adbwireless takes care of that too).

So: install adbwireless on your phone. Use it. It is possible, I do it routinely on Linux and on Windows.

Why hasn't anyone thought it was worth mentioning Scanner?

Scanner input = new Scanner(new File("foo.txt"));

while (input.hasNextLine())
{
   System.out.println(input.nextLine());
}

In Windows, do this in the command prompt from the repo directory:

cd .git
del index.lock

UPDATE: I have found that I don't need to do this procedure if I wait a moment after I close out the files I'm working on before I try to switch branches. I think sometimes this issue occurs due to git catching up with a slow file system. Other, more git-knowledgeable developers can chime in if they think this is correct.

Most layout managers work best with a component's preferredSize, and most GUI's are best off allowing the components they contain to set their own preferredSizes based on their content or properties. To use these layout managers to their best advantage, do call pack() on your top level containers such as your JFrames before making them visible as this will tell these managers to do their actions -- to layout their components.

Often when I've needed to play a more direct role in setting the size of one of my components, I'll override getPreferredSize and have it return a Dimension that is larger than the super.preferredSize (or if not then it returns the super's value).

For example, here's a small drag-a-rectangle app that I created for another question on this site:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class MoveRect extends JPanel {
   private static final int RECT_W = 90;
   private static final int RECT_H = 70;
   private static final int PREF_W = 600;
   private static final int PREF_H = 300;
   private static final Color DRAW_RECT_COLOR = Color.black;
   private static final Color DRAG_RECT_COLOR = new Color(180, 200, 255);
   private Rectangle rect = new Rectangle(25, 25, RECT_W, RECT_H);
   private boolean dragging = false;
   private int deltaX = 0;
   private int deltaY = 0;

   public MoveRect() {
      MyMouseAdapter myMouseAdapter = new MyMouseAdapter();
      addMouseListener(myMouseAdapter);
      addMouseMotionListener(myMouseAdapter);
   }

   @Override
   protected void paintComponent(Graphics g) {
      super.paintComponent(g);
      if (rect != null) {
         Color c = dragging ? DRAG_RECT_COLOR : DRAW_RECT_COLOR;
         g.setColor(c);
         Graphics2D g2 = (Graphics2D) g;
         g2.draw(rect);
      }
   }

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

   private class MyMouseAdapter extends MouseAdapter {

      @Override
      public void mousePressed(MouseEvent e) {
         Point mousePoint = e.getPoint();
         if (rect.contains(mousePoint)) {
            dragging = true;
            deltaX = rect.x - mousePoint.x;
            deltaY = rect.y - mousePoint.y;
         }
      }

      @Override
      public void mouseReleased(MouseEvent e) {
         dragging = false;
         repaint();
      }

      @Override
      public void mouseDragged(MouseEvent e) {
         Point p2 = e.getPoint();
         if (dragging) {
            int x = p2.x + deltaX;
            int y = p2.y + deltaY;
            rect = new Rectangle(x, y, RECT_W, RECT_H);
            MoveRect.this.repaint();
         }
      }
   }

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

Note that my main class is a JPanel, and that I override JPanel's getPreferredSize:

public class MoveRect extends JPanel {
   //.... deleted constants

   private static final int PREF_W = 600;
   private static final int PREF_H = 300;

   //.... deleted fields and constants

   //... deleted methods and constructors

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

Also note that when I display my GUI, I place it into a JFrame, call pack(); on the JFrame, set its position, and then call setVisible(true); on my JFrame:

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

We can use the String.CASE_INSENSITIVE_ORDER comparator to compare the strings in case insensitive order.

Arrays.binarySearch(someStringArray, "The String to find.",String.CASE_INSENSITIVE_ORDER);

Unfortunately, the answer to your question of whether there is official Material support for selecting the time is "No", but it's currently an open issue on the official Material2 GitHub repo: https://github.com/angular/material2/issues/5648

Hopefully this changes soon, in the mean time, you'll have to fight with the 3rd-party ones you've already discovered. There are a few people in that GitHub issue that provide their self-made workarounds that you can try.

Swift 3 and Above Version(s) for a delay of 10 seconds

An easy way to pull of the p-values is to use statsmodels regression:

import statsmodels.api as sm
mod = sm.OLS(Y,X)
fii = mod.fit()
p_values = fii.summary2().tables[1]['P>|t|']

You get a series of p-values that you can manipulate (for example choose the order you want to keep by evaluating each p-value):

I had the same error, with URLs containing non-ascii chars (bytes with values > 128)

url = url.decode('utf8').encode('utf-8')

Worked for me, in Python 2.7, I suppose this assignment changed 'something' in the str internal representation--i.e., it forces the right decoding of the backed byte sequence in url and finally puts the string into a utf-8 str with all the magic in the right place. Unicode in Python is black magic for me. Hope useful

    first_list = [1, 2, 2, 5]
    second_list = [2, 5, 7, 9]

    newList=[]
    for i in first_list:
        newList.append(i)
    for z in second_list:
        if z not in newList:
            newList.append(z)
    newList.sort()
    print newList

You can also use vbNewLine Object as in

MessageLabel.Text = "The Sales tax was:" & Format(douSales_tax, "Currency") & "." & vbNewLine & "The sale person: " & mstrSalesPerson

What you want is lazy iteration over an object or array. This is not possible in ES5 (thus not possible in node.js). We will get this eventually.

The only solution is finding a node module that extends V8 to implement iterators (and probably generators). I couldn't find any implementation. You can look at the spidermonkey source code and try writing it in C++ as a V8 extension.

You could try the following, however it will also load all the keys into memory

Object.keys(o).forEach(function(key) {
  var val = o[key];
  logic();
});

However since Object.keys is a native method it may allow for better optimisation.

Benchmark

As you can see Object.keys is significantly faster. Whether the actual memory storage is more optimum is a different matter.

var async = {};
async.forEach = function(o, cb) {
  var counter = 0,
    keys = Object.keys(o),
    len = keys.length;
  var next = function() {
    if (counter < len) cb(o[keys[counter++]], next);
  };
  next();
};

async.forEach(obj, function(val, next) {
  // do things
  setTimeout(next, 100);
});

The cause of your problem is NOT the Win console not willing to accept Unicode (as it does this since I guess Win2k by default). It is the default system encoding. Try this code and see what it gives you:

import sys
sys.getdefaultencoding()

if it says ascii, there's your cause ;-) You have to create a file called sitecustomize.py and put it under python path (I put it under /usr/lib/python2.5/site-packages, but that is differen on Win - it is c:\python\lib\site-packages or something), with the following contents:

import sys
sys.setdefaultencoding('utf-8')

and perhaps you might want to specify the encoding in your files as well:

# -*- coding: UTF-8 -*-
import sys,time

Edit: more info can be found in excellent the Dive into Python book

The Easiest Way to do

    public function update(Request $request, $id)
{


    $coupon = Coupon::where('name','=',$request->name)->first(); 

    if($coupon->id != $id){
        $validatedData = $request->validate([
            'discount' => 'required',   
            'name' => 'required|unique:coupons|max:255',      
        ]);
    }


    $requestData = $request->all();
    $coupon = Coupon::findOrFail($id);
    $coupon->update($requestData);
    return redirect('admin/coupons')->with('flash_message', 'Coupon updated!');
}

None of these methods helped me in Android Studio 0.5.8.

My solution was to delete ~/.AndroidStudioPreview directory (in Ubuntu). Sorry, I have no idea where is it in other OS. This directory stores temporary files and Android Studio settings, so I missed all my settings. But it works!

There are two easy methods:

1. Use backslash \ before double quotes.
2. Use two single quotes instead of double quotes like '' instead of "

For example:

System.out.println("\"Hello\"");                       
System.out.println("''Hello''"); 

You could extend Element to include a method getDirectDesc() like this:

Element.prototype.getDirectDesc = function() {
    const descendants = Array.from(this.querySelectorAll('*'));
    const directDescendants = descendants.filter(ele => ele.parentElement === this)
    return directDescendants
}

const parent = document.querySelector('.parent')
const directDescendants = parent.getDirectDesc();

document.querySelector('h1').innerHTML = `Found ${directDescendants.length} direct descendants`

<ol class="parent">
    <li class="b">child 01</li>
    <li class="b">child 02</li>
    <li class="b">child 03 <ol>
            <li class="c">Not directDescendants 01</li>
            <li class="c">Not directDescendants 02</li>
        </ol>
    </li>
    <li class="b">child 04</li>
    <li class="b">child 05</li>
    </ol>

Normally, I would go with what the documentation says but if the instructor explicitly said to stick with JDK 6, I'd use JDK 6 because you would want your development environment to be as close as possible to the instructors. It would suck if you ran into an issue and having the thought in the back of your head that maybe it's because you're on JDK 7 that you're having the issue. Btw, I haven't touched Android recently but I personally never ran into issues when I was on JDK 7 but mind you, I only code Android apps casually.

Use .charAt() and .slice().

Example: http://jsfiddle.net/kCpNQ/

var myString = "0String";

if( myString.charAt( 0 ) === '0' )
    myString = myString.slice( 1 );

If there could be several 0 characters at the beginning, you can change the if() to a while().

Example: http://jsfiddle.net/kCpNQ/1/

var myString = "0000String";

while( myString.charAt( 0 ) === '0' )
    myString = myString.slice( 1 );

The return value of os.system is OS-dependant.

On Unix, the return value is a 16-bit number that contains two different pieces of information. From the documentation:

a 16-bit number, whose low byte is the signal number that killed the process, and whose high byte is the exit status (if the signal number is zero)

So if the signal number (low byte) is 0, it would, in theory, be safe to shift the result by 8 bits (result >> 8) to get the error code. The function os.WEXITSTATUS does exactly this. If the error code is 0, that usually means that the process exited without errors.

On Windows, the documentation specifies that the return value of os.system is shell-dependant. If the shell is cmd.exe (the default one), the value is the return code of the process. Again, 0 would mean that there weren't errors.

For others error codes:

• on Linux
• on Windows

The line below throws exception if the key does not exists.

IEnumerable<string> headerValues = request.Headers.GetValues("MyCustomID");

Work around :

Include System.Linq;

IEnumerable<string> headerValues;
var userId = string.Empty;

     if (request.Headers.TryGetValues("MyCustomID", out headerValues))
     {
         userId = headerValues.FirstOrDefault();
     }           

I believe that using "cbind" is the simplest way to add a column to a data frame in R. Below an example:

    myDf = data.frame(index=seq(1,10,1), Val=seq(1,10,1))
    newCol= seq(2,20,2)
    myDf = cbind(myDf,newCol)

maxAge = Persons.Max(c => c.age)

or something along those lines.

Swift 5.1. Use with two extension, method return CALayer, so you would reuse it to update frames.

enum Border: Int {
    case top = 0
    case bottom
    case right
    case left
}

extension UIView {
    func addBorder(for side: Border, withColor color: UIColor, borderWidth: CGFloat) -> CALayer {
       let borderLayer = CALayer()
       borderLayer.backgroundColor = color.cgColor

       let xOrigin: CGFloat = (side == .right ? frame.width - borderWidth : 0)
       let yOrigin: CGFloat = (side == .bottom ? frame.height - borderWidth : 0)

       let width: CGFloat = (side == .right || side == .left) ? borderWidth : frame.width
       let height: CGFloat = (side == .top || side == .bottom) ? borderWidth : frame.height

       borderLayer.frame = CGRect(x: xOrigin, y: yOrigin, width: width, height: height)
       layer.addSublayer(borderLayer)
       return borderLayer
    }
}

extension CALayer {
    func updateBorderLayer(for side: Border, withViewFrame viewFrame: CGRect) {
        let xOrigin: CGFloat = (side == .right ? viewFrame.width - frame.width : 0)
        let yOrigin: CGFloat = (side == .bottom ? viewFrame.height - frame.height : 0)

        let width: CGFloat = (side == .right || side == .left) ? frame.width : viewFrame.width
        let height: CGFloat = (side == .top || side == .bottom) ? frame.height : viewFrame.height

        frame = CGRect(x: xOrigin, y: yOrigin, width: width, height: height)
    }
}

To put it analogously to SQL "Pandas merge is to outer/inner join and Pandas join is to natural join". Hence when you use merge in pandas, you want to specify which kind of sqlish join you want to use whereas when you use pandas join, you really want to have a matching column label to ensure it joins

I saying that the case statement is wrong but this can be a good solution instead. If you choose to use the CASE statement, you have to make sure that at least one of the CASE condition is matched. Otherwise, you need to define an error handler to catch the error. Recall that you don’t have to do this with the IF statement.

SELECT if(hide = 0,FALSE,TRUE) col FROM tbl; #for BOOLEAN Value return

or

SELECT if(hide = 0,'FALSE','TRUE') col FROM tbl; #for string Value return

Use ToArray() on List<T>.

I also like to do the communication between 2 siblings via a parent component via input and output. it handles OnPush change notification better than using a common service. Or just use NgRx Store.

Example.

            [Notes]="(NotesList$ | async)"
            (selectedNote)="ReceiveSelectedNote($event)"
        </notes-grid>
        <note-edit 
            [gridSelectedNote]="(SelectedNote$ | async)"
        </note-edit></div>`,
    styleUrls: ['./parent.component.scss']
})
export class ParentComponent {

    // create empty observable
    NotesList$: Observable<Note[]> = of<Note[]>([]);
    SelectedNote$: Observable<Note> = of<Note>();

    //passed from note-grid for selected note to edit.
    ReceiveSelectedNote(selectedNote: Note) {
    if (selectedNote !== null) {
        // change value direct subscribers or async pipe subscribers will get new value.
        this.SelectedNote$ = of<Note>(selectedNote);
    }
    }
    //used in subscribe next() to http call response.  Left out all that code for brevity.  This just shows how observable is populated.
    onNextData(n: Note[]): void {
    // Assign to Obeservable direct subscribers or async pipe subscribers will get new value.
    this.NotesList$ = of<Note[]>(n.NoteList);  //json from server
    }
}

//child 1 sibling
@Component({
  selector: 'note-edit',
  templateUrl: './note-edit.component.html', // just a textarea for noteText and submit and cancel buttons.
  styleUrls: ['./note-edit.component.scss'],
  changeDetection: ChangeDetectionStrategy.OnPush
})
export class NoteEditComponent implements OnChanges {
  @Input() gridSelectedNote: Note;

    constructor() {
    }

// used to capture @Input changes for new gridSelectedNote input
ngOnChanges(changes: SimpleChanges) {
     if (changes.gridSelectedNote && changes.gridSelectedNote.currentValue !== null) {      
      this.noteText = changes.gridSelectedNote.currentValue.noteText;
      this.noteCreateDtm = changes.gridSelectedNote.currentValue.noteCreateDtm;
      this.noteAuthorName = changes.gridSelectedNote.currentValue.noteAuthorName;
      }
  }

}

I didn't want to depend on ejs for simply delivering an HTML file, so I simply wrote the tiny renderer myself:

const Promise = require( "bluebird" );
const fs      = Promise.promisifyAll( require( "fs" ) );

app.set( "view engine", "html" );
app.engine( ".html", ( filename, request, done ) => {
    fs.readFileAsync( filename, "utf-8" )
        .then( html => done( null, html ) )
        .catch( done );
} );

Just hit the same problem... For some reason, the freezepanes command just caused crosshairs to appear in the centre of the screen. It turns oout I had switched ScreenUpdating off! Solved with the following code:

Application.ScreenUpdating = True
Cells(2, 1).Select
ActiveWindow.FreezePanes = True

Now it works fine.

I was facing the same problem while using Windows 10. I have solved the problem using the following procedure

1. Download Java from https://java.com/en/download/windows-64bit.jsp for 64-bit windows\Install it
2. Download Java development kit from https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html for 64-bit windows\Install it
3. Then right click on “This PC” icon in desktop\Properties\Advanced system settings\Advanced\Environment Variables\Under System variables select Path\Click Edit\Click on New\Copy and paste paths “C:\Program Files\Java\jdk1.8.0_201\bin” and “C:\Program Files\Java\jre1.8.0_201\bin” (without quote) \OK\OK\OK

Note: jdk1.8.0_201 and jre1.8.0_201 will be changed depending on the version of Java development kit and Java

4. In Environment Variables window go to User variables for User\Click on New\Put Variable name as “JAVA_HOME” and Variable value as “C:\Program Files\Java\jdk1.8.0_201\bin”\Press OK

To check the installation, open CMD\Type javac\Press Enter and Type java\press enter It will show

In RStudio run

Sys.setenv(JAVA_HOME="C:\\Program Files\\Java\\jdk1.8.0_201")

Note: jdk1.8.0_201 will be changed depending on the version of Java development kit

Now you can install and load rJava package without any problem.

Using CSS+

<div class="EXTENDER">

  </div>
</div>

take a look HERE

• ExecuteScalar is typically used when your query returns a single value. If it returns more, then the result is the first column of the first row. An example might be SELECT @@IDENTITY AS 'Identity'.
• ExecuteReader is used for any result set with multiple rows/columns (e.g., SELECT col1, col2 from sometable).
• ExecuteNonQuery is typically used for SQL statements without results (e.g., UPDATE, INSERT, etc.).

13-permission-denied-while-connecting-to-upstreamnginx on centos server -

setsebool -P httpd_can_network_connect 1

this syntax :

SELECT *
FROM tbl_directorylisting listing
WHERE (civilite_etudiant IS NULL)

worked for me in Microsoft SQL Server 2008 (SP3)

I had the same issue using the request module to proxy POST request from somewhere else and it was because I left the host property in the header (I was copying the header from the original request).

I prefer to use negative margin, gives you more control

ul {
  margin-left: 0;
  padding-left: 20px;
  list-style: none;
}

li:before {
  content: "*";
  display: inline;
  float: left;
  margin-left: -18px;
}

you need to do an ajax HEAD request to get the filesize. with jquery it's something like this

  var req = $.ajax({
    type: "HEAD",
    url: yoururl,
    success: function () {
      alert("Size is " + request.getResponseHeader("Content-Length"));
    }
  });

Thanks @vpekar for your implementation. It helped a lot. I just found that it misses the tf-idf weight while calculating the cosine similarity. The Counter(word) returns a dictionary which has the list of words along with their occurence.

cos(q, d) = sim(q, d) = (q · d)/(|q||d|) = (sum(qi, di)/(sqrt(sum(qi2)))*(sqrt(sum(vi2))) where i = 1 to v)

• qi is the tf-idf weight of term i in the query.
• di is the tf-idf
• weight of term i in the document. |q| and |d| are the lengths of q and d.
• This is the cosine similarity of q and d . . . . . . or, equivalently, the cosine of the angle between q and d.

Please feel free to view my code here. But first you will have to download the anaconda package. It will automatically set you python path in Windows. Add this python interpreter in Eclipse.

Python has a bitwise exclusive-OR operator, it's ^:

>>> True ^ False
True
>>> True ^ True
False
>>> False ^ True
True
>>> False ^ False
False

You can use it by converting the inputs to booleans before applying xor (^):

bool(a) ^ bool(b)

Instructions for Drupal 8 / FontAwesome 5

Create a YOUR_THEME_NAME_HERE.THEME file and place it in your themes directory (ie. your_site_name/themes/your_theme_name)

Paste this into the file, it is PHP code to find the Search Block and change the value to the UNICODE for the FontAwesome icon. You can find other characters at this link https://fontawesome.com/cheatsheet.

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
}
?>

Open the CSS file of your theme (ie. your_site_name/themes/your_theme_name/css/styles.css) and then paste this in which will change all input submit text to FontAwesome. Not sure if this will work if you also want to add text in the input button though for just an icon it is fine.

Make sure you import FontAwesome, add this at the top of the CSS file

@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

then add this in the CSS

input#edit-submit {
    font-family: 'Font Awesome\ 5 Free';
    background-color: transparent;
    border: 0;  
}

FLUSH ALL CACHES AND IT SHOULD WORK FINE

Add Google Font Effects

If you are using Google Web Fonts as well you can add also add effects to the icon (see more here https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta). You need to import a Google Web Font including the effect(s) you would like to use first in the CSS so it will be

@import url('https://fonts.googleapis.com/css?family=Open+Sans:400,800&effect=3d-float');
@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

Then go back to your .THEME file and add the class for the 3D Float Effect so the code will now add a class to the input. There are different effects available. So just choose the effect you like, change the CSS for the font import and the change the value FONT-EFFECT-3D-FLOAT int the code below to font-effect-WHATEVER_EFFECT_HERE. Note effects are still in Beta and don't work in all browsers so read here before you try it https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
  $form['actions']['submit']['#attributes']['class'][] = 'font-effect-3d-float';
}
?>

I use SimpleIni. It's cross-platform.

A simple solution I used for an existing site in IE (using jQuery, but I can post back with eventListener code if you really don't know JS that well) is the following:

if (jQuery.browser.msie) {
  jQuery('#mySelect').focus(function() {
    jQuery(this).width('auto');
  }).bind('blur change', function() {
    jQuery(this).width('100%');
  });
};

Of course, use a variable (var cWidth = jQuery('#mySelect').width();) to store the previous width, but this is all that was required for ours to work as you'd expect.

Take a look at cavaj.

out: dict_values([{1:a, 2:b}])

in:  str(dict.values())[14:-3]    
out: 1:a, 2:b

Purely for visual purposes. Does not produce a useful product... Only useful if you want a long dictionary to print in a paragraph type form.

PAGEIOLATCH_SH wait type usually comes up as the result of fragmented or unoptimized index.

Often reasons for excessive PAGEIOLATCH_SH wait type are:

• I/O subsystem has a problem or is misconfigured
• Overloaded I/O subsystem by other processes that are producing the high I/O activity
• Bad index management
• Logical or physical drive misconception
• Network issues/latency
• Memory pressure
• Synchronous Mirroring and AlwaysOn AG

In order to try and resolve having high PAGEIOLATCH_SH wait type, you can check:

• SQL Server, queries and indexes, as very often this could be found as a root cause of the excessive PAGEIOLATCH_SH wait types
• For memory pressure before jumping into any I/O subsystem troubleshooting

Always keep in mind that in case of high safety Mirroring or synchronous-commit availability in AlwaysOn AG, increased/excessive PAGEIOLATCH_SH can be expected.

You can find more details about this topic in the article Handling excessive SQL Server PAGEIOLATCH_SH wait types

New ways to align items right:

Grid:

.header {
        display:grid;
        grid-template-columns: 1fr auto;
    }

Demo

Bootstrap 4. Align right:

<div class="row">
      <div class="col">left</div>
      <div class="col">
          <div class="float-right">element needs to be right aligned</div>
      </div>
</div>

Demo

#include<stdio.h>
#include<signal.h>
#include<unistd.h>

void sig_handler(int signo)
{
  if (signo == SIGINT)
    printf("received SIGINT\n");
}

int main(void)
{
  if (signal(SIGINT, sig_handler) == SIG_ERR)
  printf("\ncan't catch SIGINT\n");
  // A long long wait so that we can easily issue a signal to this process
  while(1) 
    sleep(1);
  return 0;
}

The function sig_handler checks if the value of the argument passed is equal to the SIGINT, then the printf is executed.

I guess its enough to return absolute path..

 Path.GetFileName( Request.Url.AbsolutePath )

using System.IO;

You can use Internet Explorer to browse folders and files together in tree. It is a file explorer in Favorites Window. You just need replace "favorites folder" to folder which you want see as a root folder

Try This

   SELECT DISTINCT so.name
    FROM syscomments sc
    INNER JOIN sysobjects so ON sc.id=so.id
    WHERE sc.TEXT LIKE '%your table name%'

Use a while loop that checks for the truthfulness of the array:

while array:
    value = array.pop(0)
    # do some calculation here

And it should do it without any errors or funny behaviour.

Most people have said it - Plain Old CLR Object (as opposed to the earlier POJO - Plain Old Java Object)

The POJO one came out of EJB, which required you to inherit from a specific parent class for things like value objects (what you get back from a query in an ORM or similar), so if you ever wanted to move from EJB (eg to Spring), you were stuffed.

POJO's are just classes which dont force inheritance or any attribute markup to make them "work" in whatever framework you are using.

POCO's are the same, except in .NET.

Generally it'll be used around ORM's - older (and some current ones) require you to inherit from a specific base class, which ties you to that product. Newer ones dont (nhibernate being the variant I know) - you just make a class, register it with the ORM, and you are off. Much easier.

Are you changing the env option?

Then look at this answer.

I was trying to spawn a node process and TIL that you should spread the existing environment variables when you spawn else you'll loose the PATH environment variable and possibly other important ones.

This was the fix for me:

const nodeProcess = spawn('node', ['--help'], {
  env: {
    // by default, spawn uses `process.env` for the value of `env`
    // you can _add_ to this behavior, by spreading `process.env`
    ...process.env,
    OTHER_ENV_VARIABLE: 'test',
  }
});

set TEXT_T="myfile.txt"
set /a c=1

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
    set /a c+=1
    set OUTPUT_FILE_NAME=output_%c%.txt
    echo Output file is %OUTPUT_FILE_NAME%
    echo %%i, %c%
)

On GNU-compatible systems (i.e. Linux):

find . -mtime 0 -printf '%T+\t%s\t%p\n' 2>/dev/null | sort -r | more

This will list files and directories that have been modified in the last 24 hours (-mtime 0). It will list them with the last modified time in a format that is both sortable and human-readable (%T+), followed by the file size (%s), followed by the full filename (%p), each separated by tabs (\t).

2>/dev/null throws away any stderr output, so that error messages don't muddy the waters; sort -r sorts the results by most recently modified first; and | more lists one page of results at a time.

This is happen due to the id(auto increment filed missing). If you edit it in a text editor by adding a comma for the ID field this will be solved.

Whenever you want to use ant thread safe version of ant collection object,take help of java.util.concurrent.* package. It has almost all concurrent version of unsynchronized collection objects. eg: for ArrayList, you have java.util.concurrent.CopyOnWriteArrayList

You can do Collections.synchronizedCollection(any collection object),but remember this classical synchr. technique is expensive and comes with performence overhead. java.util.concurrent.* package is less expensive and manage the performance in better way by using mechanisms like

copy-on-write,compare-and-swap,Lock,snapshot iterators,etc.

So,Prefer something from java.util.concurrent.* package

By my side, using Chrome navigator, I had to use DataView() to read an arrayBuffer

function _arrayBufferToBase64( tabU8A ) {
var binary = '';
let lecteur_de_donnees = new DataView(tabU8A);
var len = lecteur_de_donnees.byteLength;
var chaine = '';
var pos1;
for (var i = 0; i < len; i++) {
    binary += String.fromCharCode( lecteur_de_donnees.getUint8( i ) );
}
chaine = window.btoa( binary )
return chaine;}

Filter array of objects, which property matches value, returns array:

var result = jsObjects.filter(obj => {
  return obj.b === 6
})

See the MDN Docs on Array.prototype.filter()

const jsObjects = [_x000D_
  {a: 1, b: 2}, _x000D_
  {a: 3, b: 4}, _x000D_
  {a: 5, b: 6}, _x000D_
  {a: 7, b: 8}_x000D_
]_x000D_
_x000D_
let result = jsObjects.filter(obj => {_x000D_
  return obj.b === 6_x000D_
})_x000D_
_x000D_
console.log(result)

Find the value of the first element/object in the array, otherwise undefined is returned.

var result = jsObjects.find(obj => {
  return obj.b === 6
})

See the MDN Docs on Array.prototype.find()

const jsObjects = [_x000D_
  {a: 1, b: 2}, _x000D_
  {a: 3, b: 4}, _x000D_
  {a: 5, b: 6}, _x000D_
  {a: 7, b: 8}_x000D_
]_x000D_
_x000D_
let result = jsObjects.find(obj => {_x000D_
  return obj.b === 6_x000D_
})_x000D_
_x000D_
console.log(result)

Unless I am misunderstanding what you are asking you can do this on the properties for your data grid view. You need to set the Anchor property to the sides you want it locked to.

Another way to do it without putting the property file on the classpath, is to set the property from the java code directly. Here is the sample code.

public class Log4JSample {

public static void main(String[] args) {
    Properties properties=new Properties();
    properties.setProperty("log4j.rootLogger","TRACE,stdout,MyFile");
    properties.setProperty("log4j.rootCategory","TRACE");

    properties.setProperty("log4j.appender.stdout",     "org.apache.log4j.ConsoleAppender");
    properties.setProperty("log4j.appender.stdout.layout",  "org.apache.log4j.PatternLayout");
    properties.setProperty("log4j.appender.stdout.layout.ConversionPattern","%d{yyyy/MM/dd HH:mm:ss.SSS} [%5p] %t (%F) - %m%n");

    properties.setProperty("log4j.appender.MyFile", "org.apache.log4j.RollingFileAppender");
    properties.setProperty("log4j.appender.MyFile.File", "my_example.log");
    properties.setProperty("log4j.appender.MyFile.MaxFileSize", "100KB");
    properties.setProperty("log4j.appender.MyFile.MaxBackupIndex", "1");
    properties.setProperty("log4j.appender.MyFile.layout",  "org.apache.log4j.PatternLayout");
    properties.setProperty("log4j.appender.MyFile.layout.ConversionPattern","%d{yyyy/MM/dd HH:mm:ss.SSS} [%5p] %t (%F) - %m%n");

    PropertyConfigurator.configure(properties);

    Logger logger = Logger.getLogger("MyFile");

    logger.fatal("This is a FATAL message.");
    logger.error("This is an ERROR message.");
    logger.warn("This is a WARN message.");
    logger.info("This is an INFO message.");
    logger.debug("This is a DEBUG message.");
    logger.trace("This is a TRACE message.");
}

}

You may also use LiveData that works like an EventBus.

class MyService : LifecycleService() {
    companion object {
        val BUS = MutableLiveData<Any>()
    }

    override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
        super.onStartCommand(intent, flags, startId)

        val testItem : Object

        // expose your data
        if (BUS.hasActiveObservers()) {
            BUS.postValue(testItem)
        }

        return START_NOT_STICKY
    }
}

Then add an observer from your Activity.

MyService.BUS.observe(this, Observer {
    it?.let {
        // Do what you need to do here
    }
})

You can read more from this blog.

I've solved it another way, if you like.

Here I used two arrays where searchChars containing which will be replaced and replaceChars containing desired characters.

var text = "your input string";_x000D_
var searchChars = ['Å','Ä','å','Ö','ö']; // add more charecter._x000D_
var replaceChars = ['A','A','a','O','o']; // exact same index to searchChars._x000D_
var index;_x000D_
for (var i = 0; i < text.length; i++) {_x000D_
  if( $.inArray(text[i], searchChars) >-1 ){ // $.inArray() is from jquery._x000D_
    index = searchChars.indexOf(text[i]);_x000D_
    text = text.slice(0, i) + replaceChars[index] + text.slice(i+1,text.length);_x000D_
  }_x000D_
}

This is probably the simplest way:

data$rownumber = 1:dim(data)[1]

It's probably worth noting that if you want to select a row by its row index, you can do this with simple bracket notation

data[3,]

vs.

data[data$rownumber==3,]

So I'm not really sure what this new column accomplishes.

Here is the regex for what you want with a quantifier to specify at least 1 character and no more than 255 characters

[^a-zA-Z0-9 _]{1,255}

http://wxcode.sourceforge.net/docs/wxpdfdoc/

Works with the wxWidgets library.

You'd normally use java.net.URLConnection to fire HTTP requests. You'd also normally use multipart/form-data encoding for mixed POST content (binary and character data). Click the link, it contains information and an example how to compose a multipart/form-data request body. The specification is in more detail described in RFC2388.

Here's a kickoff example:

String url = "http://example.com/upload";
String charset = "UTF-8";
String param = "value";
File textFile = new File("/path/to/file.txt");
File binaryFile = new File("/path/to/file.bin");
String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value.
String CRLF = "\r\n"; // Line separator required by multipart/form-data.

URLConnection connection = new URL(url).openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);

try (
    OutputStream output = connection.getOutputStream();
    PrintWriter writer = new PrintWriter(new OutputStreamWriter(output, charset), true);
) {
    // Send normal param.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"param\"").append(CRLF);
    writer.append("Content-Type: text/plain; charset=" + charset).append(CRLF);
    writer.append(CRLF).append(param).append(CRLF).flush();

    // Send text file.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"textFile\"; filename=\"" + textFile.getName() + "\"").append(CRLF);
    writer.append("Content-Type: text/plain; charset=" + charset).append(CRLF); // Text file itself must be saved in this charset!
    writer.append(CRLF).flush();
    Files.copy(textFile.toPath(), output);
    output.flush(); // Important before continuing with writer!
    writer.append(CRLF).flush(); // CRLF is important! It indicates end of boundary.

    // Send binary file.
    writer.append("--" + boundary).append(CRLF);
    writer.append("Content-Disposition: form-data; name=\"binaryFile\"; filename=\"" + binaryFile.getName() + "\"").append(CRLF);
    writer.append("Content-Type: " + URLConnection.guessContentTypeFromName(binaryFile.getName())).append(CRLF);
    writer.append("Content-Transfer-Encoding: binary").append(CRLF);
    writer.append(CRLF).flush();
    Files.copy(binaryFile.toPath(), output);
    output.flush(); // Important before continuing with writer!
    writer.append(CRLF).flush(); // CRLF is important! It indicates end of boundary.

    // End of multipart/form-data.
    writer.append("--" + boundary + "--").append(CRLF).flush();
}

// Request is lazily fired whenever you need to obtain information about response.
int responseCode = ((HttpURLConnection) connection).getResponseCode();
System.out.println(responseCode); // Should be 200

This code is less verbose when you use a 3rd party library like Apache Commons HttpComponents Client.

The Apache Commons FileUpload as some incorrectly suggest here is only of interest in the server side. You can't use and don't need it at the client side.

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

It provides nothing else but a standardization of the data. The values it creates are known under several different names, one of them being z-scores ("Z" because the normal distribution is also known as the "Z distribution").

Show command containing and searched: comment

I changed Edit.CommentSelection and assigned Ctrl+/ for commenting.

And I left Ctrl+K then U for the Edit.UncommentSelection.

I have a lib what use https://requests.readthedocs.io/en/master/ what use https://pypi.org/project/certifi/ but I have a custom CA included in my /etc/ssl/certs.

So I solved my problem like this:

# Your TLS certificates directory (Debian like)
export SSL_CERT_DIR=/etc/ssl/certs
# CA bundle PATH (Debian like again)
export CA_BUNDLE_PATH="${SSL_CERT_DIR}/ca-certificates.crt"
# If you have a virtualenv:
. ./.venv/bin/activate
# Get the current certifi CA bundle
CERTFI_PATH=`python -c 'import certifi; print(certifi.where())'`

test -L $CERTFI_PATH || rm $CERTFI_PATH
test -L $CERTFI_PATH || ln -s $CA_BUNDLE_PATH $CERTFI_PATH

Et voilà !

Here is the solution I came up with in my app.

In my LoginActivity, after successfully processing a login, I start the next one differently depending on the API level.

Intent i = new Intent(this, MainActivity.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    startActivity(i);
    finish();
} else {
    startActivityForResult(i, REQUEST_LOGIN_GINGERBREAD);
}

Then in my LoginActivity's onActivityForResult method:

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB &&
        requestCode == REQUEST_LOGIN_GINGERBREAD &&
        resultCode == Activity.RESULT_CANCELED) {
    moveTaskToBack(true);
}

Finally, after processing a logout in any other Activity:

Intent i = new Intent(this, LoginActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(i);

When on Gingerbread, makes it so if I press the back button from MainActivity, the LoginActivity is immediately hidden. On Honeycomb and later, I just finish the LoginActivity after processing a login and it is properly recreated after processing a logout.

try

git reflog 

this gives you a history of how your HEAD and branch pointers where moved in the past.

e.g. :

88ea06b HEAD@{0}: checkout: moving from DEVELOPMENT to remotes/origin/SomeNiceFeature e47bf80 HEAD@{1}: pull origin DEVELOPMENT: Fast-forward

the top of this list is one reasone one might encounter a DETACHED HEAD state ... checking out a remote tracking branch.

The answers using subclasses or categories to allow VCs within UINavigationController and UITabBarController classes work well. Launching a portrait-only modal from a landscape tab bar controller failed. If you need to do this, then use the trick of displaying and hiding a non-animated modal view, but do it in the viewDidAppear method. It didn't work for me in viewDidLoad or viewWillAppear.

Apart from that, the solutions above work fine.

Try passing columns of the DataFrame directly to matplotlib, as in the examples below, instead of extracting them as numpy arrays.

df = pd.DataFrame(np.random.randn(10,2), columns=['col1','col2'])
df['col3'] = np.arange(len(df))**2 * 100 + 100

In [5]: df
Out[5]: 
       col1      col2  col3
0 -1.000075 -0.759910   100
1  0.510382  0.972615   200
2  1.872067 -0.731010   500
3  0.131612  1.075142  1000
4  1.497820  0.237024  1700

Vary scatter point size based on another column

plt.scatter(df.col1, df.col2, s=df.col3)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=df.col3)

Vary scatter point color based on another column

colors = np.where(df.col3 > 300, 'r', 'k')
plt.scatter(df.col1, df.col2, s=120, c=colors)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=120, c=colors)

Scatter plot with legend

However, the easiest way I've found to create a scatter plot with legend is to call plt.scatter once for each point type.

cond = df.col3 > 300
subset_a = df[cond].dropna()
subset_b = df[~cond].dropna()
plt.scatter(subset_a.col1, subset_a.col2, s=120, c='b', label='col3 > 300')
plt.scatter(subset_b.col1, subset_b.col2, s=60, c='r', label='col3 <= 300') 
plt.legend()

Update

From what I can tell, matplotlib simply skips points with NA x/y coordinates or NA style settings (e.g., color/size). To find points skipped due to NA, try the isnull method: df[df.col3.isnull()]

To split a list of points into many types, take a look at numpy select, which is a vectorized if-then-else implementation and accepts an optional default value. For example:

df['subset'] = np.select([df.col3 < 150, df.col3 < 400, df.col3 < 600],
                         [0, 1, 2], -1)
for color, label in zip('bgrm', [0, 1, 2, -1]):
    subset = df[df.subset == label]
    plt.scatter(subset.col1, subset.col2, s=120, c=color, label=str(label))
plt.legend()

Just to add on @Lukas Eder answer.

An improvement to avoid creating tables and inserting values (we could use select from dual and unpivot to achieve the same result "on the fly"):

with all_likes as  
(select * from 
    (select '%val1%' like_1, '%val2%' like_2, '%val3%' like_3, '%val4%' as like_4, '%val5%' as like_5 from dual)
    unpivot (
     united_columns for subquery_column in ("LIKE_1", "LIKE_2", "LIKE_3", "LIKE_4", "LIKE_5"))
  )
    select * from tbl
    where exists (select 1 from all_likes where tbl.my_col like all_likes.united_columns)

To get data of ckeditor, you need to get ckeditor instance

HTML code:

Did you build the Python from source? If so, you need the --with-ssl option while building.

I'm not sure about Tomcat 7, but with Tomcat 6... once you start Tomcat: By going into the bin directory and starting startup.bat (win) or startup.sh (Unix/osx) it will spin up a local instance of the server running usually on port 8080 by default. Then by going to http://localhost:8080/ and seeing that it is running, there is a link to the manager. If that page is not there, you can try loading the manager by going directly to manager/html, and that will load the Host Manager gui.

http://localhost:8080/manager/html

Make sure Tomcat is running first and that 8080 is the right port. These are just the defaults that tomcat usually runs with.

To login you need to edit the conf/tomcat-users.xml, and create a Manager GUI role

<role rolename="manager-gui"/>

and add that to a user

<user username="admin" password="password" roles="manager-gui"/>

Then when you go to Manager GUI app at http://localhost:8080/manager/html it will prompt you for a username/password, which you added to that config file.

Using WSDL.exe didn't work for me (gave me an error about a missing type), but I was able to right-click on my project in VS and select "Add Service Reference." I entered the path to the wsdl file in the Address field and hit "Go." That seemed to be able to find all the proper types and added the classes directly to my project.

To dismiss the Viewcontroller called with the previous answers code by CmdSft

ViewController *viewController = [[ViewController alloc] init];    
[self presentViewController:viewController animated:YES completion:nil];

you can use

[self dismissViewControllerAnimated:YES completion: nil];

in python intended block mean there is every thing must be written in manner in my case I written it this way

 def btnClick(numbers):
 global operator
 operator = operator + str(numbers)
 text_input.set(operator)

Note.its give me error,until I written it in this way such that "giving spaces " then its giving me a block as I am trying to show you in function below code

def btnClick(numbers):
___________________________
|global operator
|operator = operator + str(numbers)
|text_input.set(operator)

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

list.Where(m => m.application == "applicationName" && 
           m.users.Any(u => u.surname=="surname"));

if you want to filter users as TimSchmelter commented, you can use

list.Where(m => m.application == "applicationName")
    .Select(m => new Model
    {
        application = m.application,
        users = m.users.Where(u => u.surname=="surname").ToList()
    });

Conda needs to know where to find you SSL certificate store.

conda config --set ssl_verify <pathToYourFile>.crt

No need to disable SSL verification.

This command add a line to your $HOME/.condarc file or %USERPROFILE%\.condarc file on Windows that looks like:

ssl_verify: <pathToYourFile>.crt

If you leave your organization's network, you can just comment out that line in .condarc with a # and uncomment when you return.

If it still doesn't work, make sure that you are using the latest version of curl, checking both the conda-forge and anaconda channels.

In your svn\repos\YourRepo\conf folder you will find two files, authz and passwd. These are the two you need to adjust.

In the passwd file you need to add some usernames and passwords. I assume you have already done this since you have people using it:

[users]
User1=password1
User2=password2

Then you want to assign permissions accordingly with the authz file:

Create the conceptual groups you want, and add people to it:

[groups]
allaccess = user1
someaccess = user2

Then choose what access they have from both the permissions and project level.

So let's give our "all access" guys all access from the root:

[/]
@allaccess = rw

But only give our "some access" guys read-only access to some lower level project:

[/someproject]
@someaccess = r

You will also find some simple documentation in the authz and passwd files.

You can use Message box to show success message. This works great for me.

MessageBox.Show("Data inserted successfully");

I use

ps -C "keyword" -o pid=

This command should give you a PID number.

purls $.params() used without a parameter will give you a key-value object of the parameters.

jQuerys $.param() will build a querystring from the supplied object/array.

var params = parsedUrl.param();
delete params["page"];

var newUrl = "?page=" + $(this).val() + "&" + $.param(params);

Update
I've no idea why I used delete here...

var params = parsedUrl.param();
params["page"] = $(this).val();

var newUrl = "?" + $.param(params);

Use this:

ALTER TABLE users AUTO_INCREMENT=1001;

or if you haven't already added an id column, also add it

ALTER TABLE users ADD id INT UNSIGNED NOT NULL AUTO_INCREMENT,
    ADD INDEX (id);

I had the same problem and i found the following solution to be very efficient. I hope that it will help you or everyone else who wants to do the same thing.

First of all, i would start with a "with" statement as it ensures the proper open/close of the file.

It should look something like this:

with open("filename.txt", "r+") as f:
    contents = [x.strip() for x in f.readlines()]

If you want to convert those strings (every item in the contents list is a string) in integer or float you can do the following:

contents = [float(contents[i]) for i in range(len(contents))]

Use int instead of float if you want to convert to integer.

It's my first answer in SO, so sorry if it's not in the proper formatting.

If you are trying to "Submit and Reset" the the "form" with one Button click, Try this!

Here I have used jQuery function, it can be done by simple JavaScript also...

        <form id="form_data">
           <input type="anything"  name="anything" />
           <input type="anything"  name="anything" />

             <!-- Save and Reset button -->
           <button type="button" id="btn_submit">Save</button>
           <button type="reset" id="btn_reset" style="display: none;"></button>
        </form>

<script type="text/javascript">
$(function(){
    $('#btn_submit').click(function(){
        // Do what ever you want
       $('#btn_reset').click();  // Clicking reset button
    });
});
</script>

You can listen on whatever port you want; generally, user applications should listen to ports 1024 and above (through 65535). The main thing if you have a variable number of listeners is to allocate a range to your app - say 20000-21000, and CATCH EXCEPTIONS. That is how you will know if a port is unusable (used by another process, in other words) on your computer.

However, in your case, you shouldn't have a problem using a single hard-coded port for your listener, as long as you print an error message if the bind fails.

Note also that most of your sockets (for the slaves) do not need to be explicitly bound to specific port numbers - only sockets that wait for incoming connections (like your master here) will need to be made a listener and bound to a port. If a port is not specified for a socket before it is used, the OS will assign a useable port to the socket. When the master wants to respond to a slave that sends it data, the address of the sender is accessible when the listener receives data.

I presume you will be using UDP for this?

this could works, if you are receiving a json or an xml from the service and i think this can give you an idea about how the headers and the T type works too, if you use the function MakeXmlRequest(put results in xmldocumnet) and MakeJsonRequest(put the json in the class you wish that have the same structure that the json response) in the next way

For Single valued associations, i.e.-One-to-One and Many-to-One:-
Default Lazy=proxy
Proxy lazy loading:- This implies a proxy object of your associated entity is loaded. This means that only the id connecting the two entities is loaded for the proxy object of associated entity.
Eg: A and B are two entities with Many to one association. ie: There may be multiple A's for every B. Every object of A will contain a reference of B.
`

public class A{
    int aid;
    //some other A parameters;
    B b;
}
public class B{
    int bid;
     //some other B parameters;
}

`
The relation A will contain columns(aid,bid,...other columns of entity A).
The relation B will contain columns(bid,...other columns of entity B)
Proxy implies when A is fetched, only id is fetched for B and stored into a proxy object of B which contains only id. Proxy object of B is a an object of a proxy-class which is a subclass of B with only minimal fields. Since bid is already part of relation A, it is not necessary to fire a query to get bid from the relation B. Other attributes of entity B are lazily loaded only when a field other than bid is accessed.

For Collections, i.e.-Many-to-Many and One-to-Many:-
Default Lazy=true


Please also note that the fetch strategy(select,join etc) can override lazy. ie: If lazy='true' and fetch='join', fetching of A will also fetch B or Bs(In case of collections). You can get the reason if you think about it.
Default fetch for single valued association is "join".
Default fetch for collections is "select". Please verify the last two lines. I have deduced that logically.

var newDate = new Date();
newDate.setTime(unixtime*1000);
dateString = newDate.toUTCString();

Where unixtime is the time returned by your sql db. Here is a fiddle if it helps.

For example, using it for the current time:

document.write( new Date().toUTCString() );

You're using S_ISREG() and S_ISDIR() correctly, you're just using them on the wrong thing.

In your while((dit = readdir(dip)) != NULL) loop in main, you're calling stat on currentPath over and over again without changing currentPath:

if(stat(currentPath, &statbuf) == -1) {
    perror("stat");
    return errno;
}

Shouldn't you be appending a slash and dit->d_name to currentPath to get the full path to the file that you want to stat? Methinks that similar changes to your other stat calls are also needed.

.header {

}

.wrapper {
  height: calc(100% - 64px);
  overflow-y: auto;

Or, you can use flexbox for a more dynamic approach http://jsfiddle.net/19zbs7je/3/

<div id="container">
  <div class="section">
    <div class="header">Heading</div>
    <div class="wrapper">
      <p>Large Text</p>
    </div>
  </div>
</div>

html, body {
  margin: 0px;
  padding: 0px;
  height: 100%;
}

#container {
  display: flex;
  flex-direction: column;
  height: 100%;
}

.section {
  flex-grow: 1;
  display: flex;
  flex-direction: column;
  min-height: 0;
}

.header {
  height: 64px;
  background-color: lightblue;
  flex-shrink: 0;
}

.wrapper {
  flex-grow: 1;
  overflow: auto;
  min-height: 100%; 
}

Ever heard about appserver from techdivision?

It is written in php and works as a appserver managing multithreads for high traffic php applications. Is still in beta but very promesing.

WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.presenceOfElementLocated(By.id("myDynamicElement")));

This waits up to 10 seconds before throwing a TimeoutException or if it finds the element will return it in 0 - 10 seconds. WebDriverWait by default calls the ExpectedCondition every 500 milliseconds until it returns successfully. A successful return is for ExpectedCondition type is Boolean return true or not null return value for all other ExpectedCondition types.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("someid")));

Element is Clickable - it is Displayed and Enabled.

Get the first character of a bare python string:

>>> mystring = "hello"
>>> print(mystring[0])
h
>>> print(mystring[:1])
h
>>> print(mystring[3])
l
>>> print(mystring[-1])
o
>>> print(mystring[2:3])
l
>>> print(mystring[2:4])
ll

Get the first character from a string in the first position of a python list:

>>> myarray = []
>>> myarray.append("blah")
>>> myarray[0][:1]
'b'
>>> myarray[0][-1]
'h'
>>> myarray[0][1:3]
'la'

Many people get tripped up here because they are mixing up operators of Python list objects and operators of Numpy ndarray objects:

Numpy operations are very different than python list operations.

Wrap your head around the two conflicting worlds of Python's "list slicing, indexing, subsetting" and then Numpy's "masking, slicing, subsetting, indexing, then numpy's enhanced fancy indexing".

These two videos cleared things up for me:

"Losing your Loops, Fast Numerical Computing with NumPy" by PyCon 2015: https://youtu.be/EEUXKG97YRw?t=22m22s

"NumPy Beginner | SciPy 2016 Tutorial" by Alexandre Chabot LeClerc: https://youtu.be/gtejJ3RCddE?t=1h24m54s

Using the following imports:

import {Observable} from 'rxjs/Observable';
import 'rxjs/add/observable/of';
import 'rxjs/add/operator/delay';

Try this:

let fakeResponse = [1,2,3];
let delayedObservable = Observable.of(fakeResponse).delay(5000);
delayedObservable.subscribe(data => console.log(data));

UPDATE: RXJS 6

The above solution doesn't really work anymore in newer versions of RXJS (and of angular for example).

So the scenario is that I have an array of items to check with an API with. The API only accepts a single item, and I do not want to kill the API by sending all requests at once. So I need a timed release of items on the Observable stream with a small delay in between.

Use the following imports:

import { from, of } from 'rxjs';
import { delay } from 'rxjs/internal/operators';
import { concatMap } from 'rxjs/internal/operators';

Then use the following code:

const myArray = [1,2,3,4];

from(myArray).pipe(
        concatMap( item => of(item).pipe ( delay( 1000 ) ))
    ).subscribe ( timedItem => {
        console.log(timedItem)
    });

It basically creates a new 'delayed' Observable for every item in your array. There are probably many other ways of doing it, but this worked fine for me, and complies with the 'new' RXJS format.

None of the above solutions worked for me. But this did:

myImage.Source = new BitmapImage(new Uri(@"/Images/foo.png", UriKind.Relative));

The only time to use java.sql.Date is in a PreparedStatement.setDate. Otherwise, use java.util.Date. It's telling that ResultSet.getDate returns a java.sql.Date but it can be assigned directly to a java.util.Date.

The solutions so far are all quite complicated. The idiomatic solution should doubtless be:

String.Join(",", x.Cast(Of String)().ToArray())

There's no need for fancy acrobatics in new framework versions. Supposing a not-so-modern version, the following would be easiest:

Console.WriteLine(String.Join(",", CType(x.ToArray(GetType(String)), String())))

mspmsp's second solution is a nice approach as well but it's not working because it misses the AddressOf keyword. Also, Convert.ToString is rather inefficient (lots of unnecessary internal evaluations) and the Convert class is generally not very cleanly designed. I tend to avoid it, especially since it's completely redundant.

Here is an option using while:

def number_format(n):
   n2, n3 = n, 0
   while n2 >= 1e3:
      n2 /= 1e3
      n3 += 1
   return '%.3f' % n2 + ('', ' k', ' M', ' G')[n3]

s = number_format(9012345678)
print(s == '9.012 G')

https://docs.python.org/reference/compound_stmts.html#while

In Java (and many OOP languages, but I cannot speak for all; and some do not have static at all) all methods have a fixed signature - the parameters and types. In a virtual method, the first parameter is implied: a reference to the object itself and when called from within the object, the compiler automatically adds this.

There is no difference for static methods - they still have a fixed signature. However, by declaring the method static you have explicitly stated that the compiler must not include the implied object parameter at the beginning of that signature. Therefore, any other code that calls this must must not attempt to put a reference to an object on the stack. If it did do that, then the method execution would not work since the parameters would be in the wrong place - shifted by one - on the stack.

Because of this difference between the two; virtual methods always have a reference to the context object (i.e. this) so then it is possible to reference anything within the heap that belong to that instance of the object. But with static methods, since there is no reference passed, that method cannot access any object variables and methods since the context is not known.

If you wish that Java would change the definition so that a object context is passed in for every method, static or virtual, then you would in essence have only virtual methods.

As someone asked in a comment to the op - what is your reason and purpose for wanting this feature?

I do not know Ruby much, as this was mentioned by the OP, I did some research. I see that in Ruby classes are really a special kind of object and one can create (even dynamically) new methods. Classes are full class objects in Ruby, they are not in Java. This is just something you will have to accept when working with Java (or C#). These are not dynamic languages, though C# is adding some forms of dynamic. In reality, Ruby does not have "static" methods as far as I could find - in that case these are methods on the singleton class object. You can then override this singleton with a new class and the methods in the previous class object will call those defined in the new class (correct?). So if you called a method in the context of the original class it still would only execute the original statics, but calling a method in the derived class, would call methods either from the parent or sub-class. Interesting and I can see some value in that. It takes a different thought pattern.

Since you are working in Java, you will need to adjust to that way of doing things. Why they did this? Well, probably to improve performance at the time based on the technology and understanding that was available. Computer languages are constantly evolving. Go back far enough and there is no such thing as OOP. In the future, there will be other new ideas.

EDIT: One other comment. Now that I see the differences and as I Java/C# developer myself, I can understand why the answers you get from Java developers may be confusing if you are coming from a language like Ruby. Java static methods are not the same as Ruby class methods. Java developers will have a hard time understanding this, as will conversely those who work mostly with a language like Ruby/Smalltalk. I can see how this would also be greatly confusing by the fact that Java also uses "class method" as another way to talk about static methods but this same term is used differently by Ruby. Java does not have Ruby style class methods (sorry); Ruby does not have Java style static methods which are really just old procedural style functions, as found in C.

By the way - thanks for the question! I learned something new for me today about class methods (Ruby style).

Matlab allows you to return multiple values as well as receive them inline.

When you call it, receive individual variables inline:

[array, listp, freep] = initialize(size)

<?php 
 $current = strtotime(date("Y-m-d"));
 $date    = strtotime("2014-09-05");

 $datediff = $date - $current;
 $difference = floor($datediff/(60*60*24));
 if($difference==0)
 {
    echo 'today';
 }
 else if($difference > 1)
 {
    echo 'Future Date';
 }
 else if($difference > 0)
 {
    echo 'tomorrow';
 }
 else if($difference < -1)
 {
    echo 'Long Back';
 }
 else
 {
    echo 'yesterday';
 }  
?>

just set position: fixed to the footer element (instead of relative)

Jsbin example

Note that you may need to also set a margin-bottom to the main element at least equal to the height of the footer element (e.g. margin-bottom: 1.5em;) otherwise, in some circustances, the bottom area of the main content could be partially overlapped by your footer

There's an Abstract Class Dictionary

http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html

However this requires implementation.

Java gives us a nice implementation called a Hashtable

If you do not need to use Authentication you can add configs to ngrok commands

ngrok http 9000 --host-header=rewrite

or

ngrok http 9000 --host-header="localhost:9000"

But in this case Authentication will not work on your website because ngrok rewriting headers and session is not valid for your ngrok domain

Option 2

If you are using webpack you can add the following configuration

devServer: {
    disableHostCheck: true
}

In that case Authentication header will be valid for your ngrok domain

Are you concerned about the profile picture size? at the time of implementing login with Facebook using PHP. We’ll show you the simple way to get large size profile picture in Facebook PHP SDK. Also, you can get the custom size image of Facebook profile.

Set the profile picture dimension by using the following line of code.

$userProfile = $facebook->api('/me?fields=picture.width(400).height(400)');

check this post:http://www.codexworld.com/how-to-guides/get-large-size-profile-picture-in-facebook-php-sdk/

You can achieve it by code also, In you Global.asax file in Session_Start event write response.redirect to your start page like following.

void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started

            Response.Redirect("~/Index.aspx");

        }

You can get redirect page name from database or any other storage to change the application start page while application is running no need to edit web.config or change any IIS settings

The main difference is

1.Constructor are used to initialize the state of object,where as method is expose the behaviour of object.

2.Constructor must not have return type where as method must have return type.

3.Constructor name same as the class name where as method may or may not the same class name.

4.Constructor invoke implicitly where as method invoke explicitly.

5.Constructor compiler provide default constructor where as method compiler does't provide.

That would be the modulo operator, which produces the remainder of the division of two numbers.

To further my answer, UPS and FedEx can not deliver to a PO BOX not without using the USPS as final handler. Most shipping software out there will not allow a PO Box zip for their standard services. Examples of PO Box zips are 00604 - RAMEY, PR and 06141 - HARTFORD, CT.

The the whole need to validate zip codes can really be a question of how far do you go, what is the budget, what is the time line.

Like anything with expressions test, test, test, and test again. I had an expression for State validation and found that YORK passed when it should fail. The one time in thousands someone entered New York, New York 10279, ugh.

Also keep in mind, USPS does not like punctuation such as N. Market St. and also has very specific acceptable abbreviations for things like Lane, Place, North, Corporation and the like.

Update 1/5/2018 - over the last 9 years, my thinking has evolved considerably on this topic. I tend to live a little closer to the bleeding edge in our industry than the majority (though certainly not pushing the boundaries nearly as much as a lot of really smart people out there). I've been an architect at varying levels from application, to solution, to enterprise, at multiple companies large and small. I've come to the conclusion that the future in our technology industry is one mostly without architects. If this sounds crazy to you, wait a few years and your company will probably catch up, or your competitors who figure it out will catch up with (and pass) you. The fundamental problem is that "architecture" is nothing more or less than the sum of all the decisions that have been made about your application/solution/portfolio. So the title "architect" really means "decider". That says a lot, also by what it doesn't say. It doesn't say "builder". Creating a career path / hierarchy that implicitly tells people "building" is lower than "deciding", and "deciders" are not directly responsible (by the difference in title) for "building". People who are still hanging on to their architect title will chafe at this and protest "but I am hands-on!" Great, if you're just a builder then give up your meaningless title and stop setting yourself apart from the other builders. Companies that emphasize "all builders are deciders, and all deciders are builders" will move faster than their competitors. We use the title "engineer" for everyone, and "engineer" means deciding and building.

Original answer:

For people who have never worked in a very large organization (or have, but it was a dysfunctional one), "architect" may have left a bad taste in their mouth. However, it is not only a legitimate role, but a highly strategic one for smart companies.

• When an application becomes so vast and complex that dealing with the overall technical vision and planning, and translating business needs into technical strategy becomes a full-time job, that is an application architect. Application architects also often mentor and/or lead developers, and know the code of their responsible application(s) well.

• When an organization has so many applications and infrastructure inter-dependencies that it is a full-time job to ensure their alignment and strategy without being involved in the code of any of them, that is a solution architect. Solution architect can sometimes be similar to an application architect, but over a suite of especially large applications that comprise a logical solution for a business.

• When an organization becomes so large that it becomes a full-time job to coordinate the high-level planning for the solution architects, and frame the terms of the business technology strategy, that role is an enterprise architect. Enterprise architects typically work at an executive level, advising the CxO office and its support functions as well as the business as a whole.

There are also infrastructure architects, information architects, and a few others, but in terms of total numbers these comprise a smaller percentage than the "big three".

Note: numerous other answers have said there is "no standard" for these titles. That is not true. Go to any Fortune 1000 company's IT department and you will find these titles used consistently.

The two most common misconceptions about "architect" are:

• An architect is simply a more senior/higher-earning developer with a fancy title
• An architect is someone who is technically useless, hasn't coded in years but still throws around their weight in the business, making life difficult for developers

These misconceptions come from a lot of architects doing a pretty bad job, and organizations doing a terrible job at understanding what an architect is for. It is common to promote the top programmer into an architect role, but that is not right. They have some overlapping but not identical skillsets. The best programmer may often be, but is not always, an ideal architect. A good architect has a good understanding of many technical aspects of the IT industry; a better understanding of business needs and strategies than a developer needs to have; excellent communication skills and often some project management and business analysis skills. It is essential for architects to keep their hands dirty with code and to stay sharp technically. Good ones do.

If it's not important to use a RelativeLayout, you could use a LinearLayout, and do this:

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

Doing this allows you to avoid the addRule method you've tried. You can simply use addView() to add new TextViews.

Complete code:

String[] textArray = {"One", "Two", "Three", "Four"};
LinearLayout linearLayout = new LinearLayout(this);
setContentView(linearLayout);
linearLayout.setOrientation(LinearLayout.VERTICAL);        
for( int i = 0; i < textArray.length; i++ )
{
    TextView textView = new TextView(this);
    textView.setText(textArray[i]);
    linearLayout.addView(textView);
}

I found an easier way to do it and it works perfectly even if you don't know the path where the chrome is located.

First of all, you have to paste this code in the top of the module.

Option Explicit
Private pWebAddress As String
Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
(ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, _
ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

After that you have to create this two modules:

Sub LoadExplorer()
    LoadFile "Chrome.exe" ' Here you are executing the chrome. exe
End Sub

Sub LoadFile(FileName As String)
    ShellExecute 0, "Open", FileName, "http://test.123", "", 1 ' You can change the URL.
End Sub

With this you will be able (if you want) to set a variable for the url or just leave it like hardcode.

Ps: It works perfectly for others browsers just changing "Chrome.exe" to opera, bing, etc.

Replacing forward(/) slash with backward(\) slash will do the job. The folder separator in Windows is \ not /

To stop a for loop early in JavaScript, you use break:

var remSize = [], 
    szString,
    remData,
    remIndex,
    i;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = -1; // Set a default if we don't find it
for (i = 0; i < remSize.length; i++) {      
     // I'm looking for the index i, when the condition is true
     if (remSize[i].size === remData.size) {
          remIndex = i;
          break;       // <=== breaks out of the loop early
     }
}

If you're in an ES2015 (aka ES6) environment, for this specific use case, you can use Array#findIndex (to find the entry's index) or Array#find (to find the entry itself), both of which can be shimmed/polyfilled:

var remSize = [], 
    szString,
    remData,
    remIndex;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = remSize.findIndex(function(entry) {
     return entry.size === remData.size;
});

Array#find:

var remSize = [], 
    szString,
    remData,
    remEntry;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remEntry = remSize.find(function(entry) {
     return entry.size === remData.size;
});

Array#findIndex stops the first time the callback returns a truthy value, returning the index for that call to the callback; it returns -1 if the callback never returns a truthy value. Array#find also stops when it finds what you're looking for, but it returns the entry, not its index (or undefined if the callback never returns a truthy value).

If you're using an ES5-compatible environment (or an ES5 shim), you can use the new some function on arrays, which calls a callback until the callback returns a truthy value:

var remSize = [], 
    szString,
    remData,
    remIndex;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = -1; // <== Set a default if we don't find it
remSize.some(function(entry, index) {
    if (entry.size === remData.size) {
        remIndex = index;
        return true; // <== Equivalent of break for `Array#some`
    }
});

If you're using jQuery, you can use jQuery.each to loop through an array; that would look like this:

var remSize = [], 
    szString,
    remData,
    remIndex;

/* ...I assume there's code here putting entries in `remSize` and assigning something to `remData`... */

remIndex = -1; // <== Set a default if we don't find it
jQuery.each(remSize, function(index, entry) {
    if (entry.size === remData.size) {
        remIndex = index;
        return false; // <== Equivalent of break for jQuery.each
    }
});

There is a UDF that will do that described here:

    SET @Length = (@End - @Start) + 1
    WHILE @Start > 0 AND @End > 0 AND @Length > 0

    END
    RETURN LTRIM(RTRIM(@HTMLText))

Above correct answer is very old it needs something new so Here is answer

As in last update we have androidx support so first include dependency in your app level build.gradle file

implementation 'com.google.android.gms:play-services-location:17.0.0'

then add in your manifest file:

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

don't forget to take user consent for these permissions if you are releasing

now here is code just use it

 protected void createLocationRequest() {
    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setInterval(10000);
    locationRequest.setFastestInterval(5000);
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

This is called partial functions and there are at least 3 ways to do this. My favorite way is using lambda because it avoids dependency on extra package and is the least verbose. Assume you have a function add(x, y) and you want to pass add(3, y) to some other function as parameter such that the other function decides the value for y.

Use lambda

# generic function takes op and its argument
def runOp(op, val):
    return op(val)

# declare full function
def add(x, y):
    return x+y

# run example
def main():
    f = lambda y: add(3, y)
    result = runOp(f, 1) # is 4

Create Your Own Wrapper

Here you need to create a function that returns the partial function. This is obviously lot more verbose.

# generic function takes op and its argument
def runOp(op, val):
    return op(val)

# declare full function
def add(x, y):
    return x+y

# declare partial function
def addPartial(x):
    def _wrapper(y):
        return add(x, y)
    return _wrapper

# run example
def main():
    f = addPartial(3)
    result = runOp(f, 1) # is 4

Use partial from functools

This is almost identical to lambda shown above. Then why do we need this? There are few reasons. In short, partial might be bit faster in some cases (see its implementation) and that you can use it for early binding vs lambda's late binding.

from functools import partial

# generic function takes op and its argument
def runOp(op, val):
    return op(val)

# declare full function
def add(x, y):
    return x+y

# run example
def main():
    f = partial(add, 3)
    result = runOp(f, 1) # is 4

The problem is with the string

"C:\Users\Eric\Desktop\beeline.txt"

Here, \U in "C:\Users... starts an eight-character Unicode escape, such as \U00014321. In your code, the escape is followed by the character 's', which is invalid.

You either need to duplicate all backslashes:

"C:\\Users\\Eric\\Desktop\\beeline.txt"

Or prefix the string with r (to produce a raw string):

r"C:\Users\Eric\Desktop\beeline.txt"

Well, I am quite surprised that the alternatives to this syntax have not been mentioned. Another common (but older) mechanism is to call a function that isn't defined and rely on the optimizer to compile-out the function call if your assertion is correct.

#define MY_COMPILETIME_ASSERT(test)              \
    do {                                         \
        extern void you_did_something_bad(void); \
        if (!(test))                             \
            you_did_something_bad(void);         \
    } while (0)

While this mechanism works (as long as optimizations are enabled) it has the downside of not reporting an error until you link, at which time it fails to find the definition for the function you_did_something_bad(). That's why kernel developers starting using tricks like the negative sized bit-field widths and the negative-sized arrays (the later of which stopped breaking builds in GCC 4.4).

In sympathy for the need for compile-time assertions, GCC 4.3 introduced the error function attribute that allows you to extend upon this older concept, but generate a compile-time error with a message of your choosing -- no more cryptic "negative sized array" error messages!

#define MAKE_SURE_THIS_IS_FIVE(number)                          \
    do {                                                        \
        extern void this_isnt_five(void) __attribute__((error(  \
                "I asked for five and you gave me " #number))); \
        if ((number) != 5)                                      \
            this_isnt_five();                                   \
    } while (0)

In fact, as of Linux 3.9, we now have a macro called compiletime_assert which uses this feature and most of the macros in bug.h have been updated accordingly. Still, this macro can't be used as an initializer. However, using by statement expressions (another GCC C-extension), you can!

#define ANY_NUMBER_BUT_FIVE(number)                           \
    ({                                                        \
        typeof(number) n = (number);                          \
        extern void this_number_is_five(void) __attribute__(( \
                error("I told you not to give me a five!"))); \
        if (n == 5)                                           \
            this_number_is_five();                            \
        n;                                                    \
    })

This macro will evaluate its parameter exactly once (in case it has side-effects) and create a compile-time error that says "I told you not to give me a five!" if the expression evaluates to five or is not a compile-time constant.

So why aren't we using this instead of negative-sized bit-fields? Alas, there are currently many restrictions of the use of statement expressions, including their use as constant initializers (for enum constants, bit-field width, etc.) even if the statement expression is completely constant its self (i.e., can be fully evaluated at compile-time and otherwise passes the __builtin_constant_p() test). Further, they cannot be used outside of a function body.

Hopefully, GCC will amend these shortcomings soon and allow constant statement expressions to be used as constant initializers. The challenge here is the language specification defining what is a legal constant expression. C++11 added the constexpr keyword for just this type or thing, but no counterpart exists in C11. While C11 did get static assertions, which will solve part of this problem, it wont solve all of these shortcomings. So I hope that gcc can make a constexpr functionality available as an extension via -std=gnuc99 & -std=gnuc11 or some such and allow its use on statement expressions et. al.

You can combine pseudo-elements! Sorry guys, I figured this one out myself shortly after posting the question. Maybe it's less commonly used because of compatibility issues.

li:last-child:before { content: "and "; }

li:last-child:after { content: "."; }

This works swimmingly. CSS is kind of amazing.

Use this code in model

public function funcname($id)
{
    $this->db->select('*');
    $this->db->from('Album a'); 
    $this->db->join('Category b', 'b.cat_id=a.cat_id', 'left');
    $this->db->join('Soundtrack c', 'c.album_id=a.album_id', 'left');
    $this->db->where('c.album_id',$id);
    $this->db->order_by('c.track_title','asc');         
    $query = $this->db->get(); 
    if($query->num_rows() != 0)
    {
        return $query->result_array();
    }
    else
    {
        return false;
    }
}

You should try sqlldr's SKIP_INDEX_MAINTENANCE parameter.

You won't be able to get that from a TimeSpan, because a "month" is a variable unit of measure. You'll have to calculate it yourself, and you'll have to figure out how exactly you want it to work.

For example, should dates like July 5, 2009 and August 4, 2009 yield one month or zero months difference? If you say it should yield one, then what about July 31, 2009 and August 1, 2009? Is that a month? Is it simply the difference of the Month values for the dates, or is it more related to an actual span of time? The logic for determining all of these rules is non-trivial, so you'll have to determine your own and implement the appropriate algorithm.

If all you want is simply a difference in the months--completely disregarding the date values--then you can use this:

public static int MonthDifference(this DateTime lValue, DateTime rValue)
{
    return (lValue.Month - rValue.Month) + 12 * (lValue.Year - rValue.Year);
}

Note that this returns a relative difference, meaning that if rValue is greater than lValue, then the return value will be negative. If you want an absolute difference, you can use this:

public static int MonthDifference(this DateTime lValue, DateTime rValue)
{
    return Math.Abs((lValue.Month - rValue.Month) + 12 * (lValue.Year - rValue.Year));
}

try port 25 instead of 456.

I got the same error when using port 456, and changing it to 25 worked for me.

I just had to figure this out for a client presentation and found a work around to having the GIF play a few times by making a fake loop.

• Open the Gif in Photoshop
• View the timeline
• Select all the instances and duplicate them (I did it 10 times)
• Export as a MP4
• Open up your PDF and go to TOOLS> RICH MEDIA>ADD VIDEO> then place the video of your gif where you would want it
• A window comes up, be sure to click on SHOW ADVANCED OPTIONS
• Choose your file and right underneath select ENABLE WHEN CONTENT IS VISIBLE

Hope this helps.
