You can't use this keyword like -

props.load(this.getClass().getResourceAsStream("myProps.properties"));

in a static context.

The best thing would be to get hold of application context like -

ApplicationContext context = new ClassPathXmlApplicationContext("classpath:/META-INF/spring/app-context.xml");

then you can load the resource file from the classpath -

//load a properties file from class path, inside static method
        prop.load(context.getClassLoader().getResourceAsStream("config.properties"));

This will work for both static and non static context and the best part is this properties file can be in any package/folder included in the application's classpath.

You can resave the image and literally find the src file of your project and add it to that when you save. For me I had to go to netbeans and found my project and when that comes up it had 3 files src was the last. Don't click on any of them just save your pic there. That should work. Now resizing it may be a different issue and one I'm working on now lol

I search three places as shown below. Comments welcome.

public URL getResource(String resource){

    URL url ;

    //Try with the Thread Context Loader. 
    ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
    if(classLoader != null){
        url = classLoader.getResource(resource);
        if(url != null){
            return url;
        }
    }

    //Let's now try with the classloader that loaded this class.
    classLoader = Loader.class.getClassLoader();
    if(classLoader != null){
        url = classLoader.getResource(resource);
        if(url != null){
            return url;
        }
    }

    //Last ditch attempt. Get the resource from the classpath.
    return ClassLoader.getSystemResource(resource);
}

There is an article on javaworld.com that explains the difference => Which ClassLoader should you use

(1)

Thread context classloaders provide a back door around the classloading delegation scheme.

Take JNDI for instance: its guts are implemented by bootstrap classes in rt.jar (starting with J2SE 1.3), but these core JNDI classes may load JNDI providers implemented by independent vendors and potentially deployed in the application's -classpath. This scenario calls for a parent classloader (the primordial one in this case) to load a class visible to one of its child classloaders (the system one, for example). Normal J2SE delegation does not work, and the workaround is to make the core JNDI classes use thread context loaders, thus effectively "tunneling" through the classloader hierarchy in the direction opposite to the proper delegation.

(2) from the same source:

This confusion will probably stay with Java for some time. Take any J2SE API with dynamic resource loading of any kind and try to guess which loading strategy it uses. Here is a sampling:

• JNDI uses context classloaders
• Class.getResource() and Class.forName() use the current classloader
• JAXP uses context classloaders (as of J2SE 1.4)
• java.util.ResourceBundle uses the caller's current classloader
• URL protocol handlers specified via java.protocol.handler.pkgs system property are looked up in the bootstrap and system classloaders only
• Java Serialization API uses the caller's current classloader by default

Plain old Java on plain old Java 7 and no other dependencies demonstrates the difference...

I put file.txt in c:\temp\ and I put c:\temp\ on the classpath.

There is only one case where there is a difference between the two call.

class J {

 public static void main(String[] a) {
    // as "absolute"

    // ok   
    System.err.println(J.class.getResourceAsStream("/file.txt") != null); 

    // pop            
    System.err.println(J.class.getClassLoader().getResourceAsStream("/file.txt") != null); 

    // as relative

    // ok
    System.err.println(J.class.getResourceAsStream("./file.txt") != null); 

    // ok
    System.err.println(J.class.getClassLoader().getResourceAsStream("./file.txt") != null); 

    // no path

    // ok
    System.err.println(J.class.getResourceAsStream("file.txt") != null); 

   // ok
   System.err.println(J.class.getClassLoader().getResourceAsStream("file.txt") != null); 
  }
}

In Window->Preferences->General->Startup and Shutdown->Workspaces, make sure that 'Prompt for Workspace on startup' is checked.

Then close eclipse and reopen.

Then you'll be prompted for a workspace to open. You can create a new workspace from that dialogue.

Or File->Switch Workspace->Other...

Those are optional settings. Leave it set as Unknown and you should be good.

Edit: If "unknown" is no longer an option, try leaving everything in that section blank.

You could use the :after pseudo-selector to achieve this, though I am unsure of the backward compatibility of that selector.

body {
    background: #000000
}
body:after {
    content:'';
    position: fixed;
    height: 100%;

I know this thread is old but anyway I'm sharing, I have to install all third part dependencies of the imported assembly - as the imported assembly wasn't included as Nuget package thus its dependencies were missing.

Here is an example of a recursive algorithm for reversing a singly linked list. On a laptop with the following spec (4G memory, Intel Core i5 2.3GHz CPU, 64 bit Windows 7), this function will run into StackOverflow error for a linked list of size close to 10,000.

My point is that we should use recursion judiciously, always taking into account of the scale of the system. Often recursion can be converted to iterative program, which scales better. (One iterative version of the same algorithm is given at the bottom of the page, it reverses a singly linked list of size 1 million in 9 milliseconds.)

    private static LinkedListNode doReverseRecursively(LinkedListNode x, LinkedListNode first){

    LinkedListNode second = first.next;

    first.next = x;

    if(second != null){
        return doReverseRecursively(first, second);
    }else{
        return first;
    }
}

public static LinkedListNode reverseRecursively(LinkedListNode head){
    return doReverseRecursively(null, head);
}

Iterative Version of the Same Algorithm:

    public static LinkedListNode reverseIteratively(LinkedListNode head){
    return doReverseIteratively(null, head);
}   

private static LinkedListNode doReverseIteratively(LinkedListNode x, LinkedListNode first) {

    while (first != null) {
        LinkedListNode second = first.next;
        first.next = x;
        x = first;

        if (second == null) {
            break;
        } else {
            first = second;
        }
    }
    return first;
}


public static LinkedListNode reverseIteratively(LinkedListNode head){
    return doReverseIteratively(null, head);
}

Just to expand niko's answer:

You can reference any image via its URL. No matter where it is, as long as it's accesible you can use it as the src. Example:

Relative location:

<img src="images/image.png">

The image is sought relative to the document's location. If your document is at http://example.com/site/document.html, then your images folder should be on the same directory where your document.html file is.

Absolute location:

<img src="/site/images/image.png">
<img src="http://example.com/site/images/image.png">

or

<img src="http://another-example.com/images/image.png">

In this case, your image will be sought from the document site's root, so, if your document.html is at http://example.com/site/document.html, the root would be at http://example.com/ (or it's respective directory on the server's filesystem, commonly www/). The first two examples are the same, since both point to the same host, Think of the first / as an alias for your server's root. In the second case, the image is located in another host, so you'd have to specify the complete URL of the image.

Regarding /, . and ..:

The / symbol will always return the root of a filesystem or site.

The single point ./ points to the same directory where you are.

And the double point ../ will point to the upper directory, or the one that contains the actual working directory.

So you can build relative routes using them.

Examples given the route http://example.com/dir/one/two/three/ and your calling document being inside three/:

"./pictures/image.png"

or just

"pictures/image.png"

Will try to find a directory named pictures inside http://example.com/dir/one/two/three/.

"../pictures/image.png"

Will try to find a directory named pictures inside http://example.com/dir/one/two/.

"/pictures/image.png"

Will try to find a directory named pictures directly at / or example.com (which are the same), on the same level as directory.

jQuery has a built-in method jQuery.grep that works similarly to the ES5 filter function from @adamse's Answer and should work fine on older browsers.

Using adamse's example:

var peoples = [
  { "name": "bob", "dinner": "pizza" },
  { "name": "john", "dinner": "sushi" },
  { "name": "larry", "dinner": "hummus" }
];

you can do the following

jQuery.grep(peoples, function (person) { return person.dinner == "sushi" });
  // => [{ "name": "john", "dinner": "sushi" }]

If you're able to successfully load a page from Eclipses internal web browser (by going to "Window"=>"Show View"=>"Other"=>"Internal Web Browser" and trying to open a page) BUT installing software from the eclipse marketplace and the "Help"=>"Install New Software" window are not working then this fix may help you (worked for me on a Windows 7 machine):

1. Go to "Window"=>"Preferences"=>"General"=>"Network Connections" and set the Active Provider to "Native".
2. Go into the Windows Control pannel and search firewall. Then select "Allow Program Through Windows Firewall" and click "Allow Other Program..." and add your eclipse installation.

3. Restart Eclipse and try refreshing a repository on the "Help"=>"Install New Software" window. It was able to successfull grab it for me.

This is the VBA that I use to open the current path in an Explorer window:

Shell Environ("windir") & "\explorer.exe """ & CurDir() & "",vbNormalFocus

• CurDir Function
• Environ Function
• Shell Function

Use "&" instead of "&".

The Flutter SDK path is certainly defined in a place where you can check it or change it, whether you created the project or not. Under Settings > Languages & Frameworks there should be a Flutter section. I found it by using the handy search bar in the Settings menu.

At the top of the Languages & Frameworks > Flutter is the Flutter SDK Path.

This is assuming that Flutter/Dart have already been installed under Plugins.

In up-to-date implementations of ES, you can use Object.entries:

for (const [key, value] of Object.entries(obj)) { }

or

Object.entries(obj).forEach(([key, value]) => ...)

If you just want to iterate over the values, then use Object.values:

for (const value of Object.values(obj)) { }

or

Object.values(obj).forEach(value => ...)

While JonSkeet's answer explains the difference in a typically excellent way there is another difference: exception handling.

Task.WaitAll throws an AggregateException when any of the tasks throws and you can examine all thrown exceptions. The await in await Task.WhenAll unwraps the AggregateException and 'returns' only the first exception.

When the program below executes with await Task.WhenAll(taskArray) the output is as follows.

19/11/2016 12:18:37 AM: Task 1 started
19/11/2016 12:18:37 AM: Task 3 started
19/11/2016 12:18:37 AM: Task 2 started
Caught Exception in Main at 19/11/2016 12:18:40 AM: Task 1 throwing at 19/11/2016 12:18:38 AM
Done.

When the program below is executed with Task.WaitAll(taskArray) the output is as follows.

19/11/2016 12:19:29 AM: Task 1 started
19/11/2016 12:19:29 AM: Task 2 started
19/11/2016 12:19:29 AM: Task 3 started
Caught AggregateException in Main at 19/11/2016 12:19:32 AM: Task 1 throwing at 19/11/2016 12:19:30 AM
Caught AggregateException in Main at 19/11/2016 12:19:32 AM: Task 2 throwing at 19/11/2016 12:19:31 AM
Caught AggregateException in Main at 19/11/2016 12:19:32 AM: Task 3 throwing at 19/11/2016 12:19:32 AM
Done.

The program:

class MyAmazingProgram
{
    public class CustomException : Exception
    {
        public CustomException(String message) : base(message)
        { }
    }

    static void WaitAndThrow(int id, int waitInMs)
    {
        Console.WriteLine($"{DateTime.UtcNow}: Task {id} started");

        Thread.Sleep(waitInMs);
        throw new CustomException($"Task {id} throwing at {DateTime.UtcNow}");
    }

    static void Main(string[] args)
    {
        Task.Run(async () =>
        {
            await MyAmazingMethodAsync();
        }).Wait();

    }

    static async Task MyAmazingMethodAsync()
    {
        try
        {
            Task[] taskArray = { Task.Factory.StartNew(() => WaitAndThrow(1, 1000)),
                                 Task.Factory.StartNew(() => WaitAndThrow(2, 2000)),
                                 Task.Factory.StartNew(() => WaitAndThrow(3, 3000)) };

            Task.WaitAll(taskArray);
            //await Task.WhenAll(taskArray);
            Console.WriteLine("This isn't going to happen");
        }
        catch (AggregateException ex)
        {
            foreach (var inner in ex.InnerExceptions)
            {
                Console.WriteLine($"Caught AggregateException in Main at {DateTime.UtcNow}: " + inner.Message);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Caught Exception in Main at {DateTime.UtcNow}: " + ex.Message);
        }
        Console.WriteLine("Done.");
        Console.ReadLine();
    }

I loop through an array of my projects for a git pull update:

#!/bin/sh
projects="

for project in $projects do
    cd  $HOME/develop/$project && git pull
end

Now I see what you are doing. You cannot send output to the screen then change the headers. If you are trying to create an XML file of map marker and download them to display, they should be in separate files.

Take this

<?php
require("database.php");
function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','&lt;',$htmlStr);
$xmlStr=str_replace('>','&gt;',$xmlStr);
$xmlStr=str_replace('"','&quot;',$xmlStr);
$xmlStr=str_replace("'",'&#39;',$xmlStr);
$xmlStr=str_replace("&",'&amp;',$xmlStr);
return $xmlStr;
}
// Opens a connection to a MySQL server
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
  die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}
header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  echo '<marker ';
  echo 'name="' . parseToXML($row['name']) . '" ';
  echo 'address="' . parseToXML($row['address']) . '" ';
  echo 'lat="' . $row['lat'] . '" ';
  echo 'lng="' . $row['lng'] . '" ';
  echo 'type="' . $row['type'] . '" ';
  echo '/>';
}
// End XML file
echo '</markers>';
?>

and place it in phpsqlajax_genxml.php so your javascript can download the XML file. You are trying to do too many things in the same file.

In a function:

a += 1

will be interpreted by the compiler as assign to a => Create local variable a, which is not what you want. It will probably fail with a a not initialized error since the (local) a has indeed not been initialized:

>>> a = 1
>>> def f():
...     a += 1
... 
>>> f()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in f
UnboundLocalError: local variable 'a' referenced before assignment

You might get what you want with the (very frowned upon, and for good reasons) global keyword, like so:

>>> def f():
...     global a
...     a += 1
... 
>>> a
1
>>> f()
>>> a
2

In general however, you should avoid using global variables which become extremely quickly out of hand. And this is especially true for multithreaded programs, where you don't have any synchronization mechanism for your thread1 to know when a has been modified. In short: threads are complicated, and you cannot expect to have an intuitive understanding of the order in which events are happening when two (or more) threads work on the same value. The language, compiler, OS, processor... can ALL play a role, and decide to modify the order of operations for speed, practicality or any other reason.

The proper way for this kind of thing is to use Python sharing tools (locks and friends), or better, communicate data via a Queue instead of sharing it, e.g. like this:

from threading import Thread
from queue import Queue
import time

def thread1(threadname, q):
    #read variable "a" modify by thread 2
    while True:
        a = q.get()
        if a is None: return # Poison pill
        print a

def thread2(threadname, q):
    a = 0
    for _ in xrange(10):
        a += 1
        q.put(a)
        time.sleep(1)
    q.put(None) # Poison pill

queue = Queue()
thread1 = Thread( target=thread1, args=("Thread-1", queue) )
thread2 = Thread( target=thread2, args=("Thread-2", queue) )

thread1.start()
thread2.start()
thread1.join()
thread2.join()

In Dart 2 int.tryParse is available.

It returns null for invalid inputs instead of throwing. You can use it like this:

int val = int.tryParse(text) ?? defaultValue;

my decision:

Array = _context.Products.OrderByDescending(p => p.Val ?? float.MinValue)

Problems only surface when I am I trying to give the first loaded content an active state

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current');

You could just use underscore library.

Install it:

   npm install underscore --save
   npm install @types/underscore --save-dev

Import it

   import _ = require('underscore');

Use it

    var x = _.filter(
      [{ "id": 1 }, { "id": -2 }, { "id": 3 }],
      myObj => myObj.id < 0)
    );

This function gives all 4 limits of the used range:

Function FindUsedRangeLimits()
    Set Sheet = ActiveSheet
    Sheet.UsedRange.Select

    ' Display the range's rows and columns.
    row_min = Sheet.UsedRange.Row
    row_max = row_min + Sheet.UsedRange.Rows.Count - 1
    col_min = Sheet.UsedRange.Column
    col_max = col_min + Sheet.UsedRange.Columns.Count - 1

    MsgBox "Rows " & row_min & " - " & row_max & vbCrLf & _
           "Columns: " & col_min & " - " & col_max
    LastCellBeforeBlankInColumn = True
End Function

You could use HorizontalContentAlignment="Stretch" as follows:

<ListBox HorizontalContentAlignment="Stretch"/>

Maybe I'm not understanding the question but here is my simple solution that works -

# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)

# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty

I agree that labels are not automatically updated but can easily be updated with the

<label name>.config(text="<new text>" + str(<variable name>))

That just needs to be included in your code after the variable is updated.

To show leading zeros infront of hours, minutes and seconds use below modified code. The trick here is we are converting (or more accurately formatting) integer into string so that it shows leading zero whenever applicable :

public String convertTimeWithTimeZome(long time) {
        Calendar cal = Calendar.getInstance();
        cal.setTimeZone(TimeZone.getTimeZone("UTC"));
        cal.setTimeInMillis(time);
        String curTime = String.format("%02d:%02d:%02d", cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE), cal.get(Calendar.SECOND));
        return curTime;
    }

Result would be like : 00:01:30

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

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

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

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

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

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

Changing text color of button

Because this method is now deprecated

button.setTextColor(getResources().getColor(R.color.your_color));

I use the following:

button.setTextColor(ContextCompat.getColor(mContext, R.color.your_color));

It gets serialized so that the URI can read the name value pairs in the POST request by default. You could try setting processData:false to your list of params. Not sure if that would help.

Adding onKeyPress will work onChange in Text Field.

<TextField
  onKeyPress={(ev) => {
    console.log(`Pressed keyCode ${ev.key}`);
    if (ev.key === 'Enter') {
      // Do code here
      ev.preventDefault();
    }
  }}
/>

You can now use css flexbox to align divs horizontally and vertically if you need to. general formula goes like this

parent-div {
  display: flex;
  flex-wrap: wrap;
  /* for horizontal aligning of child divs */
  justify-content: center;
  /* for vertical aligning */
  align-items: center;
}

child-div {
  width: /* yoursize for each div */
  ;
}

I just had this happen to me: I was getting the error only on my device and the simulator was working fine. I ended up having to reset my device and the error went away.

If you are generating select tag from ajax, add this inside success function:

$('.chosen').chosen();

Or, If you are generating select tag on clicking add more button then add:

$('.chosen').chosen();

inside the function.

I think that you should use a connection pool instead of share a single connection. A connection pool would provide a much better performance, as you can check here.

As stated in the library documentation, it occurs because the MySQL protocol is sequential (this means that you need multiple connections to execute queries in parallel).

Connection Pool Docs

If speed is a concern, why not partition off the most commonly used set of inputs and their values to a lookup table and then do whatever optimized magic algorithm you have come up with for the exceptional cases?

Use white-space: nowrap;^{[1] [2]} or give that link more space by setting li's width to greater values.

        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
    </fieldset>
</form>?

JS:

$('#checkall').checkAll('#slaves input:checkbox', {
    reportTo: function () {
        var prefix = this.prop('checked') ? 'un' : '';
        this.next().text(prefix + 'check all');
    }
});?

...and you're done.

I stumbled over this thread searching for answer to similar case. Basically all answers are found, but it's still hard to extract the essentials from them.

Kinds of Access

Assume a class Foo probably derived from some other class(es) with probably more classes derived from it.

Then accessing

• from static method/getter of Foo
  • some probably overridden static method/getter:
    • this.method()
    • this.property
  • some probably overridden instance method/getter:
    • impossible by design
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • impossible by design
• from instance method/getter of Foo
  • some probably overridden static method/getter:
    • this.constructor.method()
    • this.constructor.property
  • some probably overridden instance method/getter:
    • this.method()
    • this.property
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • not possible by intention unless using some workaround:
      • Foo.prototype.method.call( this )
      • Object.getOwnPropertyDescriptor( Foo.prototype,"property" ).get.call(this);

Keep in mind that using this isn't working this way when using arrow functions or invoking methods/getters explicitly bound to custom value.

Background

• When in context of an instance's method or getter
  • this is referring to current instance.
  • super is basically referring to same instance, but somewhat addressing methods and getters written in context of some class current one is extending (by using the prototype of Foo's prototype).
  • definition of instance's class used on creating it is available per this.constructor.
• When in context of a static method or getter there is no "current instance" by intention and so
  • this is available to refer to the definition of current class directly.
  • super is not referring to some instance either, but to static methods and getters written in context of some class current one is extending.

Each link has five different states: link, hover, active, focus and visited.

Link is the normal appearance, hover is when you mouse over, active is the state when it's clicked, focus follows active and visited is the state you end up when you unfocus the recently clicked link.

I'm guessing you want to achieve a different style on either focus or visited, then you can add the following CSS:

a { color: #00c; }
a:visited { #ccc; }
a:focus { #cc0; }

A recommended order in your CSS to not cause any trouble is the following:

a
a:visited { ... }
a:focus { ... }
a:hover { ... }
a:active { ... }

You can use your web browser's developer tools to force the states of the element like this (Chrome->Developer Tools/Inspect Element->Style->Filter :hov): Force state in Chrome Developer Tools

Below is another way by which we can JSON data with JSON.stringify() function

var Utils = {};
Utils.MyClass1 = function (id, member) {
    this.id = id;
    this.member = member;
}
var myobject = { MyClass1: new Utils.MyClass1("5678999", "text") };
alert(JSON.stringify(myobject));

Shipping the app with a database file, in Android Studio 3.0

Shipping the app with a database file is a good idea for me. The advantage is that you don't need to do a complex initialization, which sometimes costs lots of time, if your data set is huge.

Step 1: Prepare database file

Have your database file ready. It can be either a .db file or a .sqlite file. If you use a .sqlite file, all you need to do is to change file extension names. The steps are the same.

In this example, I prepared a file called testDB.db. It has one table and some sample data in it like this

Step 2: Import the file into your project

Create the assets folder if you haven't had one. Then copy and paste the database file into this folder

Step 3: Copy the file to the app's data folder

You need to copy the database file to the app's data folder in order to do further interaction with it. This is a one time action (initialization) to copy the database file. If you call this code multiple times, the database file in data folder will be overwritten by the one in assets folder. This overwrite process is useful when you want to update the database in future during the app update.

Note that during app update, this database file will not be changed in the app's data folder. Only uninstall will delete it.

The database file needs to be copied to /databases folder. Open Device File Explorer. Enter data/data/<YourAppName>/ location. This is the app's default data folder mentioned above. And by default, the database file will be place in another folder called databases under this directory

Now, the copy file process is pretty much like the what Java is doing. Use the following code to do the copy paste. This is the initiation code. It can also be used to update(by overwriting) the database file in future.

//get context by calling "this" in activity or getActivity() in fragment
//call this if API level is lower than 17  String appDataPath = "/data/data/" + context.getPackageName() + "/databases/"
String appDataPath = context.getApplicationInfo().dataDir;

File dbFolder = new File(appDataPath + "/databases");//Make sure the /databases folder exists
dbFolder.mkdir();//This can be called multiple times.

File dbFilePath = new File(appDataPath + "/databases/testDB.db");

try {
    InputStream inputStream = context.getAssets().open("testDB.db");
    OutputStream outputStream = new FileOutputStream(dbFilePath);
    byte[] buffer = new byte[1024];
    int length;
    while ((length = inputStream.read(buffer))>0)
    {
        outputStream.write(buffer, 0, length);
    }
    outputStream.flush();
    outputStream.close();
    inputStream.close();
} catch (IOException e){
    //handle
}

Then refresh the folder to verify the copy process

Step 4: Create database open helper

Create a subclass for SQLiteOpenHelper, with connect, close, path, etc. I named it DatabaseOpenHelper

import android.content.Context;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DatabaseOpenHelper extends SQLiteOpenHelper {
    public static final String DB_NAME = "testDB.db";
    public static final String DB_SUB_PATH = "/databases/" + DB_NAME;
    private static String APP_DATA_PATH = "";
    private SQLiteDatabase dataBase;
    private final Context context;

    public DatabaseOpenHelper(Context context){
        super(context, DB_NAME, null, 1);
        APP_DATA_PATH = context.getApplicationInfo().dataDir;
        this.context = context;
    }

    public boolean openDataBase() throws SQLException{
        String mPath = APP_DATA_PATH + DB_SUB_PATH;
        //Note that this method assumes that the db file is already copied in place
        dataBase = SQLiteDatabase.openDatabase(mPath, null, SQLiteDatabase.OPEN_READWRITE);
        return dataBase != null;
    }

    @Override
    public synchronized void close(){
        if(dataBase != null) {dataBase.close();}
        super.close();
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    }
}

Step 5: Create top level class to interact with the database

This will be the class that read & write your database file. Also there is a sample query to print out the value in the database.

import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;

public class Database {
    private final Context context;
    private SQLiteDatabase database;
    private DatabaseOpenHelper dbHelper;

    public Database(Context context){
        this.context = context;
        dbHelper = new DatabaseOpenHelper(context);
    }

    public Database open() throws SQLException
    {
        dbHelper.openDataBase();
        dbHelper.close();
        database = dbHelper.getReadableDatabase();
        return this;
    }

    public void close()
    {
        dbHelper.close();
    }

    public void test(){
        try{
            String query ="SELECT value FROM test1";
            Cursor cursor = database.rawQuery(query, null);
            if (cursor.moveToFirst()){
                do{
                    String value = cursor.getString(0);
                    Log.d("db", value);
                }while (cursor.moveToNext());
            }
            cursor.close();
        } catch (SQLException e) {
            //handle
        }
    }
}

Step 6: Test running

Test the code by running the following lines of codes.

Database db = new Database(context);
db.open();
db.test();
db.close();

Hit the run button and cheer!

I tried the code and in my case the code below solve the issue. I had not settled the schema properly

@Entity
    @Table(name="table"
         ,catalog="databasename"
      )

Please try to add ,catalog="databasename" the same as I did.

,catalog="databasename"

Another approach(Inside of $function to asure that the each is executed on document ready):

var ids = [1,2];
$(function(){
  $('.checkbox-wrapper>input[type="checkbox"]').each(function(i,item){
    if(ids.indexOf($(item).data('id')) > -1){
       $(item).prop("checked", "checked");
    }
  });
});

What is the n.fn.init[0], and why it is returned? Why are my two seemingly identical JQuery functions returning different things?

Answer: It seems that your elements are not in the DOM yet, when you are trying to find them. As @Rory McCrossan pointed out, the length:0 means that it doesn't find any element based on your search criteria.

About n.fn.init[0], lets look at the core of the Jquery Library:

var jQuery = function( selector, context ) {
   return new jQuery.fn.init( selector, context );
};

Looks familiar, right?, now in a minified version of jquery, this should looks like:

var n = function( selector, context ) {
   return new n.fn.init( selector, context );
};

So when you use a selector you are creating an instance of the jquery function; when found an element based on the selector criteria it returns the matched elements; when the criteria does not match anything it returns the prototype object of the function.

If you own the class better go with Comparable. Generally Comparator is used if you dont own the class but you have to use it a TreeSet or TreeMap because Comparator can be passed as a parameter in the conctructor of TreeSet or TreeMap. You can see how to use Comparator and Comparable in http://preciselyconcise.com/java/collections/g_comparator.php

We can use execute method instead of openquery. Its code is much cleaner. I had to get linked server query result in a variable. I used following code.

CREATE TABLE #selected_store
(
   code VARCHAR(250),
   id INT
)
declare @storeId as integer = 25
insert into #selected_store (id, code) execute('SELECT store_id, code from quickstartproductionnew.store where store_id = ?', @storeId) at [MYSQL]  

declare @code as varchar(100)
select @code = code from #selected_store
select @code
drop table #selected_store

Note:

if your query doesn't work, please make sure remote proc transaction promotion is set as false for your linked server connection.

EXEC master.dbo.sp_serveroption
       @server = N'{linked server name}',
       @optname = N'remote proc transaction promotion',
       @optvalue = N'false';

CommonJS is more than that - it's a project to define a common API and ecosystem for JavaScript. One part of CommonJS is the Module specification. Node.js and RingoJS are server-side JavaScript runtimes, and yes, both of them implement modules based on the CommonJS Module spec.

AMD (Asynchronous Module Definition) is another specification for modules. RequireJS is probably the most popular implementation of AMD. One major difference from CommonJS is that AMD specifies that modules are loaded asynchronously - that means modules are loaded in parallel, as opposed to blocking the execution by waiting for a load to finish.

AMD is generally more used in client-side (in-browser) JavaScript development due to this, and CommonJS Modules are generally used server-side. However, you can use either module spec in either environment - for example, RequireJS offers directions for running in Node.js and browserify is a CommonJS Module implementation that can run in the browser.

$ git rebase --abort

Run this code at any time if you want to undo the git rebase

$ git rebase -i HEAD~2

To reapply last two commits. The above command will open a code editor

• [ The latest commit will be at the bottom ]. Change the last commit to squash(s). Since squash will meld with previous commit.
• Then press esc key and type :wq to save and close

After :wq you will be in active rebase mode

Note: You'll get another editor if no warning/error messages, If there is an error or warning another editor will not show, you may abort by runnning $ git rebase --abort if you see an error or warning else just continue by running $ git rebase --continue

You will see your 2 commit message. Choose one or write your own commit message, save and quit [:wq]

Note 2: You may need to force push your changes to the remote repo if you run rebase command

$ git push -f

$ git push -f origin master

Developers use different editions of the Java platform to create Java programs that run on desktop computers, web browsers, web servers, mobile information devices (such as feature phones), and embedded devices (such as television set-top boxes).

Java Platform, Standard Edition (Java SE): The Java platform for developing applications, which are stand-alone programs that run on desktops. Java SE is also used to develop applets, which are programs that run in web browsers.

Java Platform, Enterprise Edition (Java EE): The Java platform for developing enterprise-oriented applications and servlets, which are server programs that conform to Java EE’s Servlet API. Java EE is built on top of Java SE.

Java Platform, Micro Edition (Java ME): The Java platform for developing MIDlets, which are programs that run on mobile information devices, and Xlets, which are programs that run on embedded devices.

Maybe you could try

List<Article> findAllByPublicationDate(Date publicationDate);

The detail could be checked in this article:

https://www.baeldung.com/spring-data-jpa-query-by-date

You can use the Y-combinator: (Wikipedia)

// ES5 syntax
var Y = function Y(a) {
  return (function (a) {
    return a(a);
  })(function (b) {
    return a(function (a) {
      return b(b)(a);
    });
  });
};

// ES6 syntax
const Y = a=>(a=>a(a))(b=>a(a=>b(b)(a)));

// If the function accepts more than one parameter:
const Y = a=>(a=>a(a))(b=>a((...a)=>b(b)(...a)));

And you can use it as this:

// ES5
var fn = Y(function(fn) {
  return function(counter) {
    console.log(counter);
    if (counter > 0) {
      fn(counter - 1);
    }
  }
});

// ES6
const fn = Y(fn => counter => {
  console.log(counter);
  if (counter > 0) {
    fn(counter - 1);
  }
});

Never forget that offset() function is giving your element's position to document. So when you need scroll your element relative to its parent you should use this;

    $('.a-parent-div').find('a').click(function(event){
        event.preventDefault();
        $('.scroll-div').animate({
     scrollTop: $( $.attr(this, 'href') ).position().top + $('.scroll-div').scrollTop()
     }, 500);       
  });

The key point is getting scrollTop of scroll-div and add it to scrollTop. If you won't do that position() function always gives you different position values.

To only strip whitespaces (in my case spaces and tabs) from lines with at least one non-whitespace character (this way empty indented lines are not touched):

sed -i -r 's/([^ \t]+)[ \t]+$/\1/' "$file"

While I agree that the accepted answer is usually the best solution and definitely easier to use, I noticed no one displayed the proper usage of the iterator. So here is a quick example:

Iterator<Object> it = arrayList.iterator();
while(it.hasNext())
{
    Object obj = it.next();
    //Do something with obj
}

You can try this

var lastPostDate = reader[3] == DBNull.Value ?
                                default(DateTime?): 
                                Convert.ToDateTime(reader[3]);

String url = "https://www.thandroid-mania.com/";
if (url.startsWith("https://") || url.startsWith("http://")) {
    Uri uri = Uri.parse(url);
    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
    startActivity(intent);
}else{
    Toast.makeText(mContext, "Invalid Url", Toast.LENGTH_SHORT).show();
}

That error occurred because of invalid URL, Android OS can't find action view for your data. So you have validate that the URL is valid or not.

I'm seen this problem with Chrome too, if I remember correctly if you minimize and then maximize your window it fixes it as well?

Haven't really used Chrome too much since it was released but this is definitely something I blame on Google as the code I was checking it on was air tight.

None of the above answers worked for me, perhaps they were based on an older version of the framework?

All I needed to do was set the value of the underlying control, then call the refresh method, as below:

$("#slider").val(50);
$("#slider").slider("refresh");

Try this its worked for me

SELECT * from bookedroom
    WHERE UNIX_TIMESTAMP('2020-8-07 5:31')
        between UNIX_TIMESTAMP('2020-8-07 5:30') and
        UNIX_TIMESTAMP('2020-8-09 5:30')

It documents your intent - you will be storing small numbers, rather than a character.

Also it looks nicer if you're using other typedefs such as uint16_t or int32_t.

For Unix & Mac systems, Go to /bin/setenv.sh inside tomcat folder

Add the below line

export JAVA_OPTS="$JAVA_OPTS -DAPP_MASTER_PASSWORD=mypass"

Now System.getProperty("APP_MASTER_PASSWORD") will return "mypass"

To preselect an option when the form is initialized, the value of the select element must be set to an element attribute of the array you are iterating over and setting the value of option to. Which is the key attribute in this case.

From your example.

<select [id]="question.key" [formControlName]="question.key">
  <option *ngFor="let opt of question.options" [value]="opt.key"</option>
</select>

You are iterating over 'options' to create the select options. So the value of select must be set to the key attribute of an item in options(the one you want to display on initialization). This will display the default of select as the option whose value matches the value you set for select.

You can achieve this by setting the value of the select element in the onInit method like so.

ngOnInit(): void{
    myForm : new FormGroup({
       ...
       question.key : new FormControl(null)
    })
    // Get desired initial value to display on <select>
    desiredValue = question.options.find(opt => opt === initialValue)
    this.myForm.get(question.key).setValue(desiredValue.key)
}

Except for adding the following to sqlnet.ora

SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8

I also added the following to both the Client and Server, which resolved my issue

SQLNET.AUTHENTICATION_SERVICES = (NONE)

I haven't played around with it much but eclipse/pydev feels nice.

The top answer is much better in terms of breadth and depth of information given, but it seems like if you wanted your problem fixed almost immediately, and don't mind trodding on some of the basic principles of version control, you could ...

1. Switch to master

   $ git checkout upstream master
   

2. Delete your unwanted branch. (Note: it must be have the -D, instead of the normal -d flag because your branch is many commits ahead of the master.)

   $ git branch -d <branch_name>
   

3. Create a new branch

   $ git checkout -b <new_branch_name>
   

To solve this, you'll need to install only 2 packages. Follow the steps below.

1. Open atom, go to Packages(top bar) --> Settings View --> Install Packages/Themes.

2. Type "goto" in the search field and click the packages button on the right.

3. Install both "goto(1.8.3)" and "goto-definition(1.1.9)", or later versions. Make sure both of them are enabled after download.
4. If necessary, you can restart atom (for some people).
5. It should be able to work now. Right-Click on the method/attr/whatever, then select "Goto Definition"

I'm not sure about the syntax of your specific commands (e.g., vagrant, etc), but in general...

Just register Ansible's (not-normally-shown) JSON output to a variable, then display each variable's stdout_lines attribute:

- name: Generate SSH keys for vagrant user
  user: name=vagrant generate_ssh_key=yes ssh_key_bits=2048
  register: vagrant
- debug: var=vagrant.stdout_lines

- name: Show SSH public key
  command: /bin/cat $home_directory/.ssh/id_rsa.pub
  register: cat
- debug: var=cat.stdout_lines

- name: Wait for user to copy SSH public key
  pause: prompt="Please add the SSH public key above to your GitHub account"
  register: pause
- debug: var=pause.stdout_lines

Here is some example code to help you get started:

package com.acme;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class FileArrayProvider {

    public String[] readLines(String filename) throws IOException {
        FileReader fileReader = new FileReader(filename);
        BufferedReader bufferedReader = new BufferedReader(fileReader);
        List<String> lines = new ArrayList<String>();
        String line = null;
        while ((line = bufferedReader.readLine()) != null) {
            lines.add(line);
        }
        bufferedReader.close();
        return lines.toArray(new String[lines.size()]);
    }
}

And an example unit test:

package com.acme;

import java.io.IOException;

import org.junit.Test;

public class FileArrayProviderTest {

    @Test
    public void testFileArrayProvider() throws IOException {
        FileArrayProvider fap = new FileArrayProvider();
        String[] lines = fap
                .readLines("src/main/java/com/acme/FileArrayProvider.java");
        for (String line : lines) {
            System.out.println(line);
        }
    }
}

Hope this helps.

SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.

You can access it by right clicking on the Database in Object Explorer and selecting Tasks->Import Data...

From there wizard should be self-explanatory and easy to navigate. You choose your CSV as source, desired destination, configure columns and run the package.

If you need detailed guidance, there are plenty of guides online, here is a nice one: http://www.mssqltips.com/sqlservertutorial/203/simple-way-to-import-data-into-sql-server/

T = [L[i] for i in Idx]

new XElement("Foo",
       from s in nameValuePairList
       select
             new XElement("Bar",
                  new XAttribute("SomeAttr", "SomeAttrValue"),
                          new XElement("Name", s.Name),
                          new XElement("Value", s.Value)
                         )
            );

You can add the id="MyID123" at the start of the cartHTML text appends.

The first line would therefore be:

var cartHTML = '<div id="MyID123" class="soft_add_wrapper" onmouseover="setTimer();">';

-OR-

If you want the ID to be in a variable, then something like this:

    var MyIDvariable = "MyID123";
    var cartHTML = '<div id="'+MyIDvariable+'" class="soft_add_wrapper" onmouseover="setTimer();">';
/* ... the rest of your code ... */

I had this error before when I was executing a python3 script, after this:

sudo pip3 install requests

the problem solved, If you are using python3, give a shot.

I think this is what you need if I'm understanding you correctly:

<div id="wrapperHeader">
 <div id="header">
  <img src="images/logo.png" alt="logo" />
 </div> 
</div>



div#wrapperHeader {
 width:100%;
 height;200px; /* height of the background image? */
 background:url(images/header.png) repeat-x 0 0;
 text-align:center;
}

div#wrapperHeader div#header {
 width:1000px;
 height:200px;
 margin:0 auto;
}

div#wrapperHeader div#header img {
 width:; /* the width of the logo image */
 height:; /* the height of the logo image */
 margin:0 auto;
}

We just released preview driver for Node.JS for SQL Server connectivity. You can find it here: Introducing the Microsoft Driver for Node.JS for SQL Server.

The driver supports callbacks (here, we're connecting to a local SQL Server instance):

// Query with explicit connection
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server=(local);Database=AdventureWorks2012;Trusted_Connection={Yes}";

sql.open(conn_str, function (err, conn) {
    if (err) {
        console.log("Error opening the connection!");
        return;
    }
    conn.queryRaw("SELECT TOP 10 FirstName, LastName FROM Person.Person", function (err, results) {
        if (err) {
            console.log("Error running query!");
            return;
        }
        for (var i = 0; i < results.rows.length; i++) {
            console.log("FirstName: " + results.rows[i][0] + " LastName: " + results.rows[i][1]);
        }
    });
});

Alternatively, you can use events (here, we're connecting to SQL Azure a.k.a Windows Azure SQL Database):

// Query with streaming
var sql = require('node-sqlserver');
var conn_str = "Driver={SQL Server Native Client 11.0};Server={tcp:servername.database.windows.net,1433};UID={username};PWD={Password1};Encrypt={Yes};Database={databasename}";

var stmt = sql.query(conn_str, "SELECT FirstName, LastName FROM Person.Person ORDER BY LastName OFFSET 0 ROWS FETCH NEXT 10 ROWS ONLY");
stmt.on('meta', function (meta) { console.log("We've received the metadata"); });
stmt.on('row', function (idx) { console.log("We've started receiving a row"); });
stmt.on('column', function (idx, data, more) { console.log(idx + ":" + data);});
stmt.on('done', function () { console.log("All done!"); });
stmt.on('error', function (err) { console.log("We had an error :-( " + err); });

If you run into any problems, please file an issue on Github: https://github.com/windowsazure/node-sqlserver/issues

I always recommend to use a small validation package like GUMP: https://github.com/Wixel/GUMP

Build all you basic functions arround a library like this and is is nearly impossible to forget sanitation. "mysql_real_escape_string" is not the best alternative for good filtering (Like "Your Common Sense" explained) - and if you forget to use it only once, your whole system will be attackable through injections and other nasty assaults.

I found this to be a better solution

$(".alert-dismissible").fadeTo(2000, 500).slideUp(500, function(){
    $(".alert-dismissible").alert('close');
});

I was having this issue for the following reason.

TLDR: Check if you are sending a GET request that should be sending the parameters on the url instead of on the NSURLRequest's HTTBody property.

==================================================

I had mounted a network abstraction on my app, and it was working pretty well for all my requests.

I added a new request to another web service (not my own) and it started throwing me this error.

I went to a playground and started from the ground up building a barebones request, and it worked. So I started moving closer to my abstraction until I found the cause.

My abstraction implementation had a bug: I was sending a request that was supposed to send parameters encoded in the url and I was also filling the NSURLRequest's HTTBody property with the query parameters as well. As soon as I removed the HTTPBody it worked.

Here's another option...

events = {}
for line in csv.reader(open(os.path.join(path, 'events.txt'), "rb")):
    if line[0][0] == "#":
        continue
    events[line[0]] = line[1] if len(line) == 2 else line[1:]

As found on this website So Let’s begin by installing jEnv

1. Run this in the terminal

   brew install https://raw.github.com/gcuisinier/jenv/homebrew/jenv.rb
   

2. Add jEnv to the bash profile

   if which jenv > /dev/null; then eval "$(jenv init -)"; fi
   

3. When you first install jEnv will not have any JDK associated with it.

   For example, I just installed JDK 8 but jEnv does not know about it. To check Java versions on jEnv

   At the moment it only found Java version(jre) on the system. The * shows the version currently selected. Unlike rvm and rbenv, jEnv cannot install JDK for you. You need to install JDK manually from Oracle website.

4. Install JDK 6 from Apple website. This will install Java in /System/Library/Java/JavaVirtualMachines/. The reason we are installing Java 6 from Apple website is that SUN did not come up with JDK 6 for MAC, so Apple created/modified its own deployment version.

5. Similarly install JDK7 and JDK8.

6. Add JDKs to jEnv.

   JDK 6:

   JDK 7:

   JDK 8:

7. Check the java versions installed using jenv

   

8. So now we have 3 versions of Java on our system. To set a default version use the command

   jenv local <jenv version>
   

   Ex – I wanted Jdk 1.6 to start IntelliJ

   jenv local oracle64-1.6.0.65
   

9. check the java version

   java -version

That’s it. We now have multiple versions of java and we can switch between them easily. jEnv also has some other features, such as wrappers for Gradle, Ant, Maven, etc, and the ability to set JVM options globally or locally. Check out the documentation for more information.

Lets make it very simple:

Maven Lifecycles: 1. Clean 2. Default (build) 3. Site

Maven Phases of the Default Lifecycle: 1. Validate 2. Compile 3. Test 4. Package 5. Verify 6. Install 7. Deploy

Note: Don't mix or get confused with maven goals with maven lifecycle.

See Maven Build Lifecycle Basics1

To me it seems like the best solution is to use a directive; there's no need for the controller to know that the view is being updated.

Javascript:

var app = angular.module('app', ['directives']);

angular.module('directives', []).directive('toggleClass', function () {
    var directiveDefinitionObject = {
        restrict: 'A',
        template: '<span ng-click="localFunction()" ng-class="selected"  ng-transclude></span>',
        replace: true,
        scope: {
            model: '='
        },
        transclude: true,
        link: function (scope, element, attrs) {
            scope.localFunction = function () {
                scope.model.value = scope.$id;
            };
            scope.$watch('model.value', function () {
                // Is this set to my scope?
                if (scope.model.value === scope.$id) {
                    scope.selected = "active";
                } else {
                    // nope
                    scope.selected = '';
                }
            });
        }
    };
    return directiveDefinitionObject;
});

HTML:

<div ng-app="app" ng-init="model = { value: 'dsf'}"> <span>Click a span... then click another</span>

<br/>
<br/>
<span toggle-class model="model">span1</span>

<br/><span toggle-class model="model">span2</span>

<br/><span toggle-class model="model">span3</span>

CSS:

.active {
     color:red;
 }

I have a fiddle that demonstrates. The idea is when a directive is clicked, a function is called on the directive that sets a variable to the current scope id. Then each directive also watches the same value. If the scope ID's match, then the current element is set to be active using ng-class.

The reason to use directives, is that you no longer are dependent on a controller. In fact I don't have a controller at all (I do define a variable in the view named "model"). You can then reuse this directive anywhere in your project, not just on one controller.

I've developed a dotnet library that might come in useful. I have fixed the problem of never getting all of the data if it exceeds the buffer, which many posts have discounted. Still some problems with the solution but works descently well https://github.com/NicholasLKSharp/DotNet-TCP-Communication

I was looking for a function that would let me search for both strings and arrays (as needle) in the array (haystack), so I added to the answer by @jwueller.

Here's my code:

/**
 * Recursive in_array function
 * Searches recursively for needle in an array (haystack).
 * Works with both strings and arrays as needle.
 * Both needle's and haystack's keys are ignored, only values are compared.
 * Note: if needle is an array, all values in needle have to be found for it to
 * return true. If one value is not found, false is returned.
 * @param  mixed   $needle   The array or string to be found
 * @param  array   $haystack The array to be searched in
 * @param  boolean $strict   Use strict value & type validation (===) or just value
 * @return boolean           True if in array, false if not.
 */
function in_array_r($needle, $haystack, $strict = false) {
     // array wrapper
    if (is_array($needle)) {
        foreach ($needle as $value) {
            if (in_array_r($value, $haystack, $strict) == false) {
                // an array value was not found, stop search, return false
                return false;
            }
        }
        // if the code reaches this point, all values in array have been found
        return true;
    }

    // string handling
    foreach ($haystack as $item) {
        if (($strict ? $item === $needle : $item == $needle)
            || (is_array($item) && in_array_r($needle, $item, $strict))) {
            return true;
        }
    }
    return false;
}

I would suggest reading PEP 483 and PEP 484 and watching this presentation by Guido on type hinting.

In a nutshell: Type hinting is literally what the words mean. You hint the type of the object(s) you're using.

Due to the dynamic nature of Python, inferring or checking the type of an object being used is especially hard. This fact makes it hard for developers to understand what exactly is going on in code they haven't written and, most importantly, for type checking tools found in many IDEs (PyCharm and PyDev come to mind) that are limited due to the fact that they don't have any indicator of what type the objects are. As a result they resort to trying to infer the type with (as mentioned in the presentation) around 50% success rate.

To take two important slides from the type hinting presentation:

Why type hints?

1. Helps type checkers: By hinting at what type you want the object to be the type checker can easily detect if, for instance, you're passing an object with a type that isn't expected.
2. Helps with documentation: A third person viewing your code will know what is expected where, ergo, how to use it without getting them TypeErrors.
3. Helps IDEs develop more accurate and robust tools: Development Environments will be better suited at suggesting appropriate methods when know what type your object is. You have probably experienced this with some IDE at some point, hitting the . and having methods/attributes pop up which aren't defined for an object.

Why use static type checkers?

• Find bugs sooner: This is self-evident, I believe.
• The larger your project the more you need it: Again, makes sense. Static languages offer a robustness and control that dynamic languages lack. The bigger and more complex your application becomes the more control and predictability (from a behavioral aspect) you require.
• Large teams are already running static analysis: I'm guessing this verifies the first two points.

As a closing note for this small introduction: This is an optional feature and, from what I understand, it has been introduced in order to reap some of the benefits of static typing.

You generally do not need to worry about it and definitely don't need to use it (especially in cases where you use Python as an auxiliary scripting language). It should be helpful when developing large projects as it offers much needed robustness, control and additional debugging capabilities.

Type hinting with mypy:

In order to make this answer more complete, I think a little demonstration would be suitable. I'll be using mypy, the library which inspired Type Hints as they are presented in the PEP. This is mainly written for anybody bumping into this question and wondering where to begin.

Before I do that let me reiterate the following: PEP 484 doesn't enforce anything; it is simply setting a direction for function annotations and proposing guidelines for how type checking can/should be performed. You can annotate your functions and hint as many things as you want; your scripts will still run regardless of the presence of annotations because Python itself doesn't use them.

Anyways, as noted in the PEP, hinting types should generally take three forms:

• Function annotations (PEP 3107).
• Stub files for built-in/user modules.
• Special # type: type comments that complement the first two forms. (See: What are variable annotations? for a Python 3.6 update for # type: type comments)

Additionally, you'll want to use type hints in conjunction with the new typing module introduced in Py3.5. In it, many (additional) ABCs (abstract base classes) are defined along with helper functions and decorators for use in static checking. Most ABCs in collections.abc are included, but in a generic form in order to allow subscription (by defining a __getitem__() method).

For anyone interested in a more in-depth explanation of these, the mypy documentation is written very nicely and has a lot of code samples demonstrating/describing the functionality of their checker; it is definitely worth a read.

Function annotations and special comments:

First, it's interesting to observe some of the behavior we can get when using special comments. Special # type: type comments can be added during variable assignments to indicate the type of an object if one cannot be directly inferred. Simple assignments are generally easily inferred but others, like lists (with regard to their contents), cannot.

Note: If we want to use any derivative of containers and need to specify the contents for that container we must use the generic types from the typing module. These support indexing.

# Generic List, supports indexing.
from typing import List

# In this case, the type is easily inferred as type: int.
i = 0

# Even though the type can be inferred as of type list
# there is no way to know the contents of this list.
# By using type: List[str] we indicate we want to use a list of strings.
a = []  # type: List[str]

# Appending an int to our list
# is statically not correct.
a.append(i)

# Appending a string is fine.
a.append("i")

print(a)  # [0, 'i']

If we add these commands to a file and execute them with our interpreter, everything works just fine and print(a) just prints the contents of list a. The # type comments have been discarded, treated as plain comments which have no additional semantic meaning.

By running this with mypy, on the other hand, we get the following response:

(Python3)jimmi@jim: mypy typeHintsCode.py
typesInline.py:14: error: Argument 1 to "append" of "list" has incompatible type "int"; expected "str"

Indicating that a list of str objects cannot contain an int, which, statically speaking, is sound. This can be fixed by either abiding to the type of a and only appending str objects or by changing the type of the contents of a to indicate that any value is acceptable (Intuitively performed with List[Any] after Any has been imported from typing).

Function annotations are added in the form param_name : type after each parameter in your function signature and a return type is specified using the -> type notation before the ending function colon; all annotations are stored in the __annotations__ attribute for that function in a handy dictionary form. Using a trivial example (which doesn't require extra types from the typing module):

def annotated(x: int, y: str) -> bool:
    return x < y

The annotated.__annotations__ attribute now has the following values:

{'y': <class 'str'>, 'return': <class 'bool'>, 'x': <class 'int'>}

If we're a complete newbie, or we are familiar with Python 2.7 concepts and are consequently unaware of the TypeError lurking in the comparison of annotated, we can perform another static check, catch the error and save us some trouble:

(Python3)jimmi@jim: mypy typeHintsCode.py
typeFunction.py: note: In function "annotated":
typeFunction.py:2: error: Unsupported operand types for > ("str" and "int")

Among other things, calling the function with invalid arguments will also get caught:

annotated(20, 20)

# mypy complains:
typeHintsCode.py:4: error: Argument 2 to "annotated" has incompatible type "int"; expected "str"

These can be extended to basically any use case and the errors caught extend further than basic calls and operations. The types you can check for are really flexible and I have merely given a small sneak peak of its potential. A look in the typing module, the PEPs or the mypy documentation will give you a more comprehensive idea of the capabilities offered.

Stub files:

Stub files can be used in two different non mutually exclusive cases:

• You need to type check a module for which you do not want to directly alter the function signatures
• You want to write modules and have type-checking but additionally want to separate annotations from content.

What stub files (with an extension of .pyi) are is an annotated interface of the module you are making/want to use. They contain the signatures of the functions you want to type-check with the body of the functions discarded. To get a feel of this, given a set of three random functions in a module named randfunc.py:

def message(s):
    print(s)

def alterContents(myIterable):
    return [i for i in myIterable if i % 2 == 0]

def combine(messageFunc, itFunc):
    messageFunc("Printing the Iterable")
    a = alterContents(range(1, 20))
    return set(a)

We can create a stub file randfunc.pyi, in which we can place some restrictions if we wish to do so. The downside is that somebody viewing the source without the stub won't really get that annotation assistance when trying to understand what is supposed to be passed where.

Anyway, the structure of a stub file is pretty simplistic: Add all function definitions with empty bodies (pass filled) and supply the annotations based on your requirements. Here, let's assume we only want to work with int types for our Containers.

# Stub for randfucn.py
from typing import Iterable, List, Set, Callable

def message(s: str) -> None: pass

def alterContents(myIterable: Iterable[int])-> List[int]: pass

def combine(
    messageFunc: Callable[[str], Any],
    itFunc: Callable[[Iterable[int]], List[int]]
)-> Set[int]: pass

The combine function gives an indication of why you might want to use annotations in a different file, they some times clutter up the code and reduce readability (big no-no for Python). You could of course use type aliases but that sometime confuses more than it helps (so use them wisely).

This should get you familiarized with the basic concepts of type hints in Python. Even though the type checker used has been mypy you should gradually start to see more of them pop-up, some internally in IDEs (PyCharm,) and others as standard Python modules.

I'll try and add additional checkers/related packages in the following list when and if I find them (or if suggested).

Checkers I know of:

• Mypy: as described here.
• PyType: By Google, uses different notation from what I gather, probably worth a look.

Related Packages/Projects:

• typeshed: Official Python repository housing an assortment of stub files for the standard library.

The typeshed project is actually one of the best places you can look to see how type hinting might be used in a project of your own. Let's take as an example the __init__ dunders of the Counter class in the corresponding .pyi file:

class Counter(Dict[_T, int], Generic[_T]):
        @overload
        def __init__(self) -> None: ...
        @overload
        def __init__(self, Mapping: Mapping[_T, int]) -> None: ...
        @overload
        def __init__(self, iterable: Iterable[_T]) -> None: ...

Where _T = TypeVar('_T') is used to define generic classes. For the Counter class we can see that it can either take no arguments in its initializer, get a single Mapping from any type to an int or take an Iterable of any type.

Notice: One thing I forgot to mention was that the typing module has been introduced on a provisional basis. From PEP 411:

A provisional package may have its API modified prior to "graduating" into a "stable" state. On one hand, this state provides the package with the benefits of being formally part of the Python distribution. On the other hand, the core development team explicitly states that no promises are made with regards to the the stability of the package's API, which may change for the next release. While it is considered an unlikely outcome, such packages may even be removed from the standard library without a deprecation period if the concerns regarding their API or maintenance prove well-founded.

So take things here with a pinch of salt; I'm doubtful it will be removed or altered in significant ways, but one can never know.

^** Another topic altogether, but valid in the scope of type-hints: PEP 526: Syntax for Variable Annotations is an effort to replace # type comments by introducing new syntax which allows users to annotate the type of variables in simple varname: type statements.

See What are variable annotations?, as previously mentioned, for a small introduction to these.

Just a quick addition, because I tackled the same issue today:

With Go 1.13 it is possible to use the new isZero() method:

if reflect.ValueOf(session).IsZero() {
     // do stuff...
}

I didn't test this regarding performance, but I guess that this should be faster, than comparing via reflect.DeepEqual().

I've had to look at monster(runaway) log files (20+ GB). I used hexedit FREE version which can work with any size files. It is also open source. It is a Windows executable.

look it this piece of code from my project

I'm trying to re-order the list based on a property inside my model,

 allEmployees = new List<Employee>(allEmployees.OrderByDescending(employee => employee.Name));

but I faced a problem when a small and capital letters exist, so to solve it, I used the string comparer.

allEmployees.OrderBy(employee => employee.Name,StringComparer.CurrentCultureIgnoreCase)

as another example, consider a car class, this would be a good use of composition, a car would "have" an engine, a transmission, tires, seats, etc. It would not extend any of those classes.

    @Override
        public ArrayList<Short> create(Short key) {

}

final HashList haystack = new HashList();
final String needle = "hide and";
haystack.getOrCreate(needle).add("seek")
System.out.println(haystack.get(needle).get(0));

Or try to check your mainActivity.xml you make sure that this one
xmlns:app="http://schemas.android.com/apk/res-auto"hereis included

int uniqueId = 0;

int getUniqueId()

Add synchronized if you want it to be thread safe.

It's not your fault bae, I've had this happen sometimes when the emulator's in a weird state. Just restarting the emulator helped me.

There is hlsearch and nohlsearch. :help hlsearch will provide more information.

If you want to bind F12 to toggle it on/off you can use this:

Another reason for the error (amongst many others that cropped up when changing the target build of a Win32 project to X64) was not having the C++ 64 bit compilers installed as noted at the top of this page.
Further to philipvr's comment on child headers, (in my case) an explicit include of winnt.h being unnecessary when windows.h was being used.

Should it be necessary to manually remove a service:

1. Run Regedit or regedt32.
2. Find the registry key entry for your service under the following key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services
3. Delete the Registry Key

You will have to reboot before the list gets updated in services

You can't easily do this in a generic way: you can only convert an integer to a specific type of enum. As Nicholas has shown, this is a trivial cast if you only care about one kind of enum, but if you want to write a generic method that can handle different kinds of enums, things get a bit more complicated. You want a method along the lines of:

public static string GetEnumDescription<TEnum>(int value)
{
  return GetEnumDescription((Enum)((TEnum)value));  // error!
}

but this results in a compiler error that "int can't be converted to TEnum" (and if you work around this, that "TEnum can't be converted to Enum"). So you need to fool the compiler by inserting casts to object:

public static string GetEnumDescription<TEnum>(int value)
{
  return GetEnumDescription((Enum)(object)((TEnum)(object)value));  // ugly, but works
}

You can now call this to get a description for whatever type of enum is at hand:

GetEnumDescription<MyEnum>(1);
GetEnumDescription<YourEnum>(2);

I settled for the limitation (to some people a benefit) of having my rows only one line of text high. The CSS to contain long strings then becomes:

.datatable td {
  overflow: hidden; /* this is what fixes the expansion */
  text-overflow: ellipsis; /* not supported in all browsers, but I accepted the tradeoff */
  white-space: nowrap;
}

[edit to add:] After using my own code and initially failing, I recognized a second requirement that might help people. The table itself needs to have a fixed layout or the cells will just keep trying to expand to accomodate contents no matter what. If DataTables styles or your own styles don't already do so, you need to set it:

table.someTableClass {
  table-layout: fixed
}

Now that text is truncated with ellipses, to actually "see" the text that is potentially hidden you can implement a tooltip plugin or a details button or something. But a quick and dirty solution is to use JavaScript to set each cell's title to be identical to its contents. I used jQuery, but you don't have to:

  $('.datatable tbody td').each(function(index){
    $this = $(this);
    var titleVal = $this.text();
    if (typeof titleVal === "string" && titleVal !== '') {
      $this.attr('title', titleVal);
    }
  });

DataTables also provides callbacks at the row and cell rendering levels, so you could provide logic to set the titles at that point instead of with a jQuery.each iterator. But if you have other listeners that modify cell text, you might just be better off hitting them with the jQuery.each at the end.

This entire truncation method will ALSO have a limitation you've indicated you're not a fan of: by default columns will have the same width. I identify columns that are going to be consistently wide or consistently narrow, and explicitly set a percentage-based width on them (you could do it in your markup or with sWidth). Any columns without an explicit width get even distribution of the remaining space.

That might seem like a lot of compromises, but the end result was worth it for me.

I am not a linux guru, but I believe you want to pipe your list of output files to xargs rm -rf. I have used something like this in the past with good results. Test on a sample directory first!

EDIT - I might have misunderstood, based on the other answers that are appearing. If you can use wildcards, great. I assumed that your original list that you displayed was generated by a program to give you your "selection", so I thought piping to xargs would be the way to go.

For those of you who use Pillow, from version 2.8.0 you can:

from PIL import Image
import urllib2

im = Image.open(urllib2.urlopen(url))

or if you use requests:

from PIL import Image
import requests

im = Image.open(requests.get(url, stream=True).raw)

Many answers have been given, and a lot of them are pretty good. I just wanted to add that the check

not a

will also pass for None and other types of empty structures. If you truly want to check for an empty list, you can do this:

if isinstance(a, list) and len(a)==0:
    print("Received an empty list")

Xcode 6 update

Since Xcode's newest version there is a better solution to this:

With @IBInspectable you can set Attributes directly from within the Attributes Inspector.

This sets the User Defined Runtime Attributes for you:

There are two approaches to set this up:

Option 1 (with live updating in Storyboard)

1. Create MyCustomView.
2. This inherits from UIView.
3. Set @IBDesignable (this makes the View update live).*
4. Set your Runtime Attributes (border, etc.) with @IBInspectable
5. Change your Views Class to MyCustomView
6. Edit in Attributes Panel and see changes in Storyboard :)

`

@IBDesignable
class MyCustomView: UIView {
    @IBInspectable var cornerRadius: CGFloat = 0 {
        didSet {
            layer.cornerRadius = cornerRadius
            layer.masksToBounds = cornerRadius > 0
        }
    }
    @IBInspectable var borderWidth: CGFloat = 0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }
    @IBInspectable var borderColor: UIColor? {
        didSet {
            layer.borderColor = borderColor?.CGColor
        }
    }
}

* @IBDesignable only works when set at the start of class MyCustomView

Option 2 (not working since Swift 1.2, see comments)

Extend your UIView Class:

extension UIView {
    @IBInspectable var cornerRadius: CGFloat = 0 {
        didSet {
            layer.cornerRadius = cornerRadius
            layer.masksToBounds = cornerRadius > 0
        }
    }
    @IBInspectable var borderWidth: CGFloat = 0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }
    @IBInspectable var borderColor: UIColor? {
        didSet {
            layer.borderColor = borderColor?.CGColor
        }
    }
}

This way, your default View always has those extra editable fields in Attributes Inspector. Another advantage is that you don't have to change the class to MycustomView every time. However, one drawback to this is that you will only see your changes when you run your app.

To give an alternative (as using DocumentFragment does not seem to work): You can simulate it by iterating over the children of the newly generated node and only append those.

var e = document.createElement('div');
e.innerHTML = htmldata;

while(e.firstChild) {
    element.appendChild(e.firstChild);
}

Based on what you provided, it is pretty simple for what you need to do and you even have a number of ways to go about doing it. You'll need something that'll let you post a body with your request. Almost any programming language can do this as well as command line tools like cURL.

One you have your tool decided, you'll need to create your JSON body and submit it to the server.

An example using cURL would be (all in one line, minus the \ at the end of the first line):

curl -v -H "Content-Type: application/json" -X POST \
     -d '{"name":"your name","phonenumber":"111-111"}' http://www.abc.com/details

The above command will create a request that should look like the following:

POST /details HTTP/1.1
Host: www.abc.com
Content-Type: application/json
Content-Length: 44

{"name":"your name","phonenumber":"111-111"}

Only slightly related to the question, but try to wrap your head around this one. So un-intuitive:

import java.nio.file.*;
class Main {
  public static void main(String[] args) {
    Path p1 = Paths.get("/personal/./photos/./readme.txt");
    Path p2 = Paths.get("/personal/index.html");
    Path p3 = p1.relativize(p2);
    System.out.println(p3); //prints  ../../../../index.html  !!
  }
}

On a 32-bit JVM, the largest heap size you can theoretically set is 4gb. To use a larger heap size, you need to use a 64-bit JVM. Try the following:

java -Xmx6144M -d64

The -d64 flag is important as this tells the JVM to run in 64-bit mode.

the issue could be one of the following:

1. The CA that issued the server certificate was unknown
2. The server certificate wasn't signed by a CA, but was self signed
3. The server configuration is missing an intermediate CA

Python can use all memory available to its environment. My simple "memory test" crashes on ActiveState Python 2.6 after using about

1959167 [MiB]

On jython 2.5 it crashes earlier:

 239000 [MiB]

probably I can configure Jython to use more memory (it uses limits from JVM)

Test app:

import sys

sl = []
i = 0
# some magic 1024 - overhead of string object
fill_size = 1024
if sys.version.startswith('2.7'):
    fill_size = 1003
if sys.version.startswith('3'):
    fill_size = 497
print(fill_size)
MiB = 0
while True:
    s = str(i).zfill(fill_size)
    sl.append(s)
    if i == 0:
        try:
            sys.stderr.write('size of one string %d\n' % (sys.getsizeof(s)))
        except AttributeError:
            pass
    i += 1
    if i % 1024 == 0:
        MiB += 1
        if MiB % 25 == 0:
            sys.stderr.write('%d [MiB]\n' % (MiB))

In your app you read whole file at once. For such big files you should read the line by line.

In Swift 5 and Xcode 10.2

DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + Double(Int64(0.1 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC), execute: {

//Set status bar background colour
let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
statusBar?.backgroundColor = UIColor.red
//Set navigation bar subView background colour
   for view in controller.navigationController?.navigationBar.subviews ?? [] {
      view.tintColor = UIColor.white
      view.backgroundColor = UIColor.red
   }
})

Here i fixed status bar background colour and navigation bar background colour. If you don't want navigation bar colour comment it.

1. Function imageMorph will create a new img element therefore the id is removed. Changed to

   $("#wrapper > img")

2. You should use live() function for click event if you want you rocket lanch again.

Depending on how the proxy login works stream_context_set_default might help you.

$context  = stream_context_set_default(
  array(
    'http'=>array(
      'header'=>'Authorization: Basic ' . base64_encode('username'.':'.'userpass')
    )
  )
);
$result = file_get_contents('http://..../...');

You can use realpath() function.

resolved_file = realpath(file_path, NULL);
if (!resolved_keyfile) {
   /*File dosn't exists*/
   perror(keyfile);
   return -1;
}

Try to use the empty() function:

<xsl:if test="empty(node/ABC/node()) and empty(node/DEF/node())">
    <xsl:text>This should work</xsl:text>
</xsl:if>

This identifies ABC and DEF as empty in the sense that they do not have any child nodes (no elements, no text nodes, no processing instructions, no comments).

But, as pointed out by @Ian, your elements might not be empty really or that might not be your actual problem - you did not show what your input XML looks like.

Another cause of error could be your relative position in the tree. This way of testing conditions only works if the surrounding template matches the parent element of node or if you iterate over the parent element of node.

This Did the trick for me, for IIS 8 Windows server 2012 R2

Go to "Turn on Features"

Then go to all default setting , Next, Next, Next etc..

Then, select as shown below,

Then reset IIS (optional) but do it safer side.

This is an additional solution as its a generic problem everyone have different of problem and thus different solution. Cheers!

To hide an element, use:

display: none;
visibility: hidden;

To show an element, use:

display: block;
visibility: visible;

The difference is:

Visibility handles the visibility of the tag, the display handles space it occupies on the page.

If you set the visibility and do not change the display, even if the tags are not seen, it still occupies space.

For server/protocol errors I would try to be as REST/HTTP as possible (Compare this with you typing in URL's in your browser):

• a non existing item is called (/persons/{non-existing-id-here}). Return a 404.
• an unexpected error on the server (code bug) occured. Return a 500.
• the client user is not authorised to get the resource. Return a 401.

For domain/business logic specific errors I would say the protocol is used in the right way and there's no server internal error, so respond with an error JSON/XML object or whatever you prefer to describe your data with (Compare this with you filling in forms on a website):

• a user wants to change its account name but the user did not yet verify its account by clicking a link in an email which was sent to the user. Return {"error":"Account not verified"} or whatever.
• a user wants to order a book, but the book was sold (state changed in DB) and can't be ordered anymore. Return {"error":"Book already sold"}.

One difference is for r+ if the files does not exist, it'll not be created and open fails. But in case of a+ the file will be created if it does not exist.

Here is an easy one:

$myVar > "c:\myfilepath\myfilename.myextension"

You can also try:

Get-content "c:\someOtherPath\someOtherFile.myextension" > "c:\myfilepath\myfilename.myextension"

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

In JS, "+" concatenation works by creating a new String object.

For example, with...

var s = "Hello";

...we have one object s.

Next:

s = s + " World";

Now, s is a new object.

I'm still getting spotty results in 2017, and I have a theory: the API documentation says that the call is now only available "in a secure context", i.e. over HTTPS. I'm having trouble getting a result in my development environment (http on localhost) and I believe this is why.

Assuming you’ve literally got two date objects, you can subtract one from the other and query the resulting timedelta object for the number of days:

>>> from datetime import date
>>> a = date(2011,11,24)
>>> b = date(2011,11,17)
>>> a-b
datetime.timedelta(7)
>>> (a-b).days
7

And it works with datetimes too — I think it rounds down to the nearest day:

>>> from datetime import datetime
>>> a = datetime(2011,11,24,0,0,0)
>>> b = datetime(2011,11,17,23,59,59)
>>> a-b
datetime.timedelta(6, 1)
>>> (a-b).days
6

Use std::hex manipulator:

#include <iostream>
#include <iomanip>

int main()
{
    int x;
    std::cin >> std::hex >> x;
    std::cout << x << std::endl;

    return 0;
}

You could use AppleScript through the osascript command:

osascript -e 'tell application "Terminal" to quit'

You can't append to an actual array - the size of an array is fixed at creation time. Instead, use a List<T> which can grow as it needs to.

Alternatively, keep a list of arrays, and concatenate them all only when you've grabbed everything.

See Eric Lippert's blog post on arrays for more detail and insight than I could realistically provide :)

The SCSS way for all elements (not only buttons):

      box-shadow: 0 0 0 0 rgba(0,123,255,0) !important;
      -webkit-box-shadow: none !important;
    }
  }
}

You could import the 'os' module and use it like this :

import os
os.system('#DesiredAction')

The short answer

There is none. They are exactly the same.

The long answer

Both .htm and .html are exactly the same and will work in the same way. The choice is down to personal preference, provided you’re consistent with your file naming you won’t have a problem with either.

Depending on the configuration of the web server, one of the file types will take precedence over the other. This should not be an issue since it’s unlikely that you’ll have both index.htm and index.html sitting in the same folder.

We always use the shorter .htm for our file names since file extensions are typically 3 characters long.

AND MORE ON: http://www.sightspecific.com/~mosh/WWW_FAQ/ext.html or http://www.sightspecific.com/~mosh/WWW_FAQ/ext.htm

I think I should add this part here:
There is one single slight difference between .htm and .html files. Consider a path in your server like: mydomain.com/myfolder. If you create an index.htm file inside that folder and you open that like this:mydomain.com/myfolder/, it will goes crazy and spit out your files as it is in your server,
but if you create an index.html file in there and open that directory in your browser, it will load that file. I tested this on my VPS and found this Maybe you could somehow set your server to load index.htm files by default, but I guess the .html file is the default file type for browsers to open in each directory.

SQL Server(2012) provides another way to generate script for the SQL Server databases with its objects and data. This script can be used to copy the tables’ schema and data from the source database to the destination one in our case.

1. Using the SQL Server Management Studio, right-click on the source database from the object explorer, then from Tasks choose Generate Scripts.
2. In the Choose objects window, choose Select Specific Database Objects to specify the tables that you will generate script for, then choose the tables by ticking beside each one of it. Click Next.
3. In the Set Scripting Options window, specify the path where you will save the generated script file, and click Advanced.
4. From the appeared Advanced Scripting Options window, specify Schema and Data as Types of Data to Script. You can decide from here if you want to script the indexes and keys in your tables. Click OK. Getting back to the Advanced Scripting Options window, click Next.
5. Review the Summary window and click Next.
6. You can monitor the progress from the Save or Publish Scripts window. If there is no error click Finish and you will find the script file in the specified path.

SQL Scripting method is useful to generate one single script for the tables’ schema and data, including the indexes and keys. But again this method doesn’t generate the tables’ creation script in the correct order if there are relations between the tables.

I think there are 2 things that add confusion to this topic:

1. statistical v.s. signal processing definition: as others have pointed out, in statistics we normalize auto-correlation into [-1,1].
2. partial v.s. non-partial mean/variance: when the timeseries shifts at a lag>0, their overlap size will always < original length. Do we use the mean and std of the original (non-partial), or always compute a new mean and std using the ever changing overlap (partial) makes a difference. (There's probably a formal term for this, but I'm gonna use "partial" for now).

I've created 5 functions that compute auto-correlation of a 1d array, with partial v.s. non-partial distinctions. Some use formula from statistics, some use correlate in the signal processing sense, which can also be done via FFT. But all results are auto-correlations in the statistics definition, so they illustrate how they are linked to each other. Code below:

import numpy
import matplotlib.pyplot as plt

def autocorr1(x,lags):
    '''numpy.corrcoef, partial'''

    corr=[1. if l==0 else numpy.corrcoef(x[l:],x[:-l])[0][1] for l in lags]
    return numpy.array(corr)

def autocorr2(x,lags):
    '''manualy compute, non partial'''

    mean=numpy.mean(x)
    var=numpy.var(x)
    xp=x-mean
    corr=[1. if l==0 else numpy.sum(xp[l:]*xp[:-l])/len(x)/var for l in lags]

    return numpy.array(corr)

def autocorr3(x,lags):
    '''fft, pad 0s, non partial'''

    n=len(x)
    # pad 0s to 2n-1
    ext_size=2*n-1
    # nearest power of 2
    fsize=2**numpy.ceil(numpy.log2(ext_size)).astype('int')

    xp=x-numpy.mean(x)
    var=numpy.var(x)

    # do fft and ifft
    cf=numpy.fft.fft(xp,fsize)
    sf=cf.conjugate()*cf
    corr=numpy.fft.ifft(sf).real
    corr=corr/var/n

    return corr[:len(lags)]

def autocorr4(x,lags):
    '''fft, don't pad 0s, non partial'''
    mean=x.mean()
    var=numpy.var(x)
    xp=x-mean

    cf=numpy.fft.fft(xp)
    sf=cf.conjugate()*cf
    corr=numpy.fft.ifft(sf).real/var/len(x)

    return corr[:len(lags)]

def autocorr5(x,lags):
    '''numpy.correlate, non partial'''
    mean=x.mean()
    var=numpy.var(x)
    xp=x-mean
    corr=numpy.correlate(xp,xp,'full')[len(x)-1:]/var/len(x)

    return corr[:len(lags)]

Here is the output figure:

We don't see all 5 lines because 3 of them overlap (at the purple). The overlaps are all non-partial auto-correlations. This is because computations from the signal processing methods (np.correlate, FFT) don't compute a different mean/std for each overlap.

Also note that the fft, no padding, non-partial (red line) result is different, because it didn't pad the timeseries with 0s before doing FFT, so it's circular FFT. I can't explain in detail why, that's what I learned from elsewhere.

For one file:

git diff --no-index /dev/null new_file

For all new files:

for next in $( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null $next; done;

As alias:

alias gdnew="for next in \$( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null \$next; done;"

For all modified and new files combined as one command:

{ git --no-pager diff; gdnew }

The pipe, |, is a special-character in regex (meaning "or") and you'll have to escape it with a \.

Using your current regex:

\|.*$

I've tried this in Notepad++, as you've mentioned, and it appears to work well.

Via which interface? Using the REST interface, you just send a delete:

DELETE /ObjectName HTTP/1.1
Host: BucketName.s3.amazonaws.com
Date: date
Content-Length: length
Authorization: signatureValue

Via the SOAP interface:

<DeleteObject xmlns="http://doc.s3.amazonaws.com/2006-03-01">
  <Bucket>quotes</Bucket>
  <Key>Nelson</Key>
  <AWSAccessKeyId> 1D9FVRAYCP1VJEXAMPLE=</AWSAccessKeyId>
  <Timestamp>2006-03-01T12:00:00.183Z</Timestamp>
  <Signature>Iuyz3d3P0aTou39dzbqaEXAMPLE=</Signature>
</DeleteObject>

If you're using a Python library like boto, it should expose a "delete" feature, like delete_key().

I read through LOTS of places online to solve this thing. This is the code I wrote to make it work:

ByteArrayInputStream derInputStream = new ByteArrayInputStream(app.certificateString.getBytes());
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate) certificateFactory.generateCertificate(derInputStream);
String alias = "alias";//cert.getSubjectX500Principal().getName();

KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null);
trustStore.setCertificateEntry(alias, cert);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(trustStore, null);
KeyManager[] keyManagers = kmf.getKeyManagers();

TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");
tmf.init(trustStore);
TrustManager[] trustManagers = tmf.getTrustManagers();

SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(keyManagers, trustManagers, null);
URL url = new URL(someURL);
conn = (HttpsURLConnection) url.openConnection();
conn.setSSLSocketFactory(sslContext.getSocketFactory());

app.certificateString is a String that contains the Certificate, for example:

static public String certificateString=
        "-----BEGIN CERTIFICATE-----\n" +
        "MIIGQTCCBSmgAwIBAgIHBcg1dAivUzANBgkqhkiG9w0BAQsFADCBjDELMAkGA1UE" +
        "BhMCSUwxFjAUBgNVBAoTDVN0YXJ0Q29tIEx0ZC4xKzApBgNVBAsTIlNlY3VyZSBE" +
        ... a bunch of characters...
        "5126sfeEJMRV4Fl2E5W1gDHoOd6V==\n" +
        "-----END CERTIFICATE-----";

I have tested that you can put any characters in the certificate string, if it is self signed, as long as you keep the exact structure above. I obtained the certificate string with my laptop's Terminal command line.

I can show you an example of uploading a .txt file to a server with NSMutableURLRequest and NSURLSessionUploadTask with help of a php script.

-(void)uploadFileToServer : (NSString *) filePath
{
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://YourURL.com/YourphpScript.php"]];
[request setHTTPMethod:@"POST"]; 
[request addValue:@"File Name" forHTTPHeaderField:@"FileName"];
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultConfigObject];

NSURLSessionUploadTask* uploadTask = [defaultSession uploadTaskWithRequest:request fromFile:[NSURL URLWithString:filePath] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
                                      {
                                          NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
                                          if (error || [httpResponse statusCode]!=202)
                                          {

                                              //Error
                                          }
                                          else
                                          {
                                             //Success
                                          }
                                          [defaultSession invalidateAndCancel];
                                      }];
[uploadTask resume];
}

php Script

<?php 
$request_body = @file_get_contents('php://input');
foreach (getallheaders() as $name => $value) 
{
    if ($FileName=="FileName") 
    {
        $header=$value;
        break;
    }
}   
$uploadedDir = "directory/";
@mkdir($uploadedDir);
file_put_contents($uploadedDir."/".$FileName.".txt",
$request_body.PHP_EOL, FILE_APPEND);
header('X-PHP-Response-Code: 202', true, 202);  
?>       

To get the cell value, you need to read it directly from DataGridView1 using e.RowIndex and e.ColumnIndex properties.

Eg:

Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
   Dim value As Object = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value

   If IsDBNull(value) Then 
      TextBox1.Text = "" ' blank if dbnull values
   Else
      TextBox1.Text = CType(value, String)
   End If
End Sub

Check out Boost.Units: link text

It provides zero-overhead Dimensional analysis through operator overloading. How much clearer can this get?

quantity<force>     F = 2.0*newton;
quantity<length>    dx = 2.0*meter;
quantity<energy>    E = F * dx;
std::cout << "Energy = " << E << endl;

would actually output "Energy = 4 J" which is correct.

Use the doubleNumber.intValue(); method.

Try using @Html.DropDownList instead:

<td>Account: </td>
<td>@Html.DropDownList("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))</td>

@Html.DropDownListFor expects a lambda as its first argument, not a string for the ID as you specify.

Other than that, without knowing what getUserAccounts() consists of, suffice to say it needs to return some sort of collection (IEnumerable for example) that has at least 1 object in it. If it returns null the property in the ViewBag won't have anything.

Here's a Split function that is compatible with SQL Server versions prior to 2005.

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

Adding something to the above correct answers. I am using netbeans IDE and it shows error while using url(#{$assetPath}/site/background.jpg) this method. It was just netbeans error and no error in sass compiling. But this error break code formatting in netbeans and code become ugly. But when I use it inside quotes like below, it show wonder!

There are various ways to get a Set as:

    List<Integer> sourceList = new ArrayList();
    sourceList.add(1);
    sourceList.add(2);
    sourceList.add(3);
    sourceList.add(4);

    // Using Core Java
    Set<Integer> set1 = new HashSet<>(sourceList);  //needs null-check if sourceList can be null.

    // Java 8
    Set<Integer> set2 = sourceList.stream().collect(Collectors.toSet());
    Set<Integer> set3 = sourceList.stream().collect(Collectors.toCollection(HashSet::new));

    //Guava
    Set<Integer> set4 = Sets.newHashSet(sourceList);

    // Apache commons
    Set<Integer> set5 = new HashSet<>(4);
    CollectionUtils.addAll(set5, sourceList);

When we use Collectors.toSet() it returns a set and as per the doc:There are no guarantees on the type, mutability, serializability, or thread-safety of the Set returned. If we want to get a HashSet then we can use the other alternative to get a set (check set3).

On http://www.google.com/earth/media/licensing.html there is a "Mobile" section containing :

Similar to our online terms, if you use our APIs or a mobile device’s native Google Maps implementation (such as on an Android-powered phone or iPhone), no special permission is required, but you must always keep the Google name visible. Offline caching of our content is never allowed.

you can change color of any text by use html <font> attribute directly in xml files. for example in strings.xml :

<resources>
    <string name = "app_name">
        <html><font color="#001aff">Multi</font></html>
        <html><font color="#ff0044">color</font></html>
        <html><font color="#e9c309">Text </font></html>
    </string>
</resources>

You'll want to use Get-ChildItem to recursively get all folders and files first. And then pipe that output into a Where-Object clause which only take the files.

# one of several ways to identify a file is using GetType() which
# will return "FileInfo" or "DirectoryInfo"
$files = Get-ChildItem E:\ -Recurse | Where-Object {$_.GetType().Name -eq "FileInfo"} ;

foreach ($file in $files) {
  echo $file.FullName ;
}

another way is to provide no cache headers from serverside in the code that generates the response to ajax call:

response.setHeader( "Pragma", "no-cache" );
response.setHeader( "Cache-Control", "no-cache" );
response.setDateHeader( "Expires", 0 );

http://msdn.microsoft.com/en-us/library/ad548tzy%28VS.71%29.aspx

When using Server validator controls you have to be careful about fact that any one can disable javascript in their browser. So you should use Page.IsValid Property always at server side.

The issue of correctly pre-allocating a typed array in TypeScript was somewhat obscured for due to the array literal syntax, so it wasn't as intuitive as I first thought.

The correct way would be

var arr : Criminal[] = [];

This will give you a correctly typed, empty array stored in the variable 'arr'

Hope this helps others!

Like Yuck's answer with a check to allow the script to be ran more than once without error. (less code/custom strings than using information_schema.columns)

IF object_id('DF_SomeName', 'D') IS NULL BEGIN
    Print 'Creating Constraint DF_SomeName'
   ALTER TABLE Employee ADD CONSTRAINT DF_SomeName DEFAULT N'SANDNES' FOR CityBorn;
END

Depending on how big your arrays are you might consider an efficient algorithm O(n log n)

def equal_a(a1, a2)
  a1sorted = a1.sort
  a2sorted = a2.sort
  return false if a1.length != a2.length
  0.upto(a1.length - 1) do 
    |i| return false if a1sorted[i] != a2sorted[i]
  end
end

Sorting costs O(n log n) and checking each pair costs O(n) thus this algorithm is O(n log n). The other algorithms cannot be faster (asymptotically) using unsorted arrays.

James K Nelson in his letter "Why You Shouldn’t Style React Components With JavaScript" states that there is no actual need of using inline styles with its downsides. His statement is that old boring CSS with less/scss is the best solution. The part of his theses in favor of CSS:

• extendable externally
• severable (inline styles overleap everything)
• designer-friendly

From what I can see there are helper methods inside the ControllerBase class. Just use the StatusCode method:

[HttpPost]
public IActionResult Post([FromBody] string something)
{    
    //...
    try
    {
        DoSomething();
    }
    catch(Exception e)
    {
         LogException(e);
         return StatusCode(500);
    }
}

You may also use the StatusCode(int statusCode, object value) overload which also negotiates the content.

I had the same issue since I changed my app ID in config.xml file.

I used to open my Android project by choosing among recent projects of Android Studio.

I just File > Open > My project to get it working again.

Using git branch -r lists all remote branches and git branch -a lists all branches on local and remote. These lists get outdated though. To keep these lists up-to-date, run

git remote update --prune

which will update your local branch list with all new ones from the remote and remove any that are no longer there. Running this update command without the --prune will retrieve new branches but not delete ones no longer on the remote.

You can speed up this update by specifying a remote, otherwise it will pull updates from all remotes you have added, like so

git remote update --prune origin

The only way to reliably detect if a socket is still connected is to periodically try to send data. Its usually more convenient to define an application level 'ping' packet that the clients ignore, but if the protocol is already specced out without such a capability you should be able to configure tcp sockets to do this by setting the SO_KEEPALIVE socket option. I've linked to the winsock documentation, but the same functionality should be available on all BSD-like socket stacks.

For compare hashed password with the plain text password string you can use the PHP password_verify

if(password_verify('1234567', $crypt_password_string)) {
    // in case if "$crypt_password_string" actually hides "1234567"
}

Late reply for future reference. What was working for me was enabling it by nuget and then adding custom headers into web.config.

Send a ajax request to your server like this in your js and get your result in success function.

jQuery.ajax({
            url: "/rest/abc",
            type: "GET",

            contentType: 'application/json; charset=utf-8',
            success: function(resultData) {
                //here is your json.
                  // process it

            },
            error : function(jqXHR, textStatus, errorThrown) {
            },

            timeout: 120000,
        });

at server side send response as json type.

And you can use jQuery.getJSON for your application.

You may try CScope + tceetree + Graphviz.

In the keypress event handler:

e.Handled = true;

In Python, how do you get the last element of a list?

To just get the last element,

• without modifying the list, and
• assuming you know the list has a last element (i.e. it is nonempty)

pass -1 to the subscript notation:

>>> a_list = ['zero', 'one', 'two', 'three']
>>> a_list[-1]
'three'

Explanation

Indexes and slices can take negative integers as arguments.

I have modified an example from the documentation to indicate which item in a sequence each index references, in this case, in the string "Python", -1 references the last element, the character, 'n':

 +---+---+---+---+---+---+
 | P | y | t | h | o | n |
 +---+---+---+---+---+---+
   0   1   2   3   4   5 
  -6  -5  -4  -3  -2  -1

>>> p = 'Python'
>>> p[-1]
'n'

Assignment via iterable unpacking

This method may unnecessarily materialize a second list for the purposes of just getting the last element, but for the sake of completeness (and since it supports any iterable - not just lists):

>>> *head, last = a_list
>>> last
'three'

The variable name, head is bound to the unnecessary newly created list:

>>> head
['zero', 'one', 'two']

If you intend to do nothing with that list, this would be more apropos:

*_, last = a_list

Or, really, if you know it's a list (or at least accepts subscript notation):

last = a_list[-1]

In a function

A commenter said:

I wish Python had a function for first() and last() like Lisp does... it would get rid of a lot of unnecessary lambda functions.

These would be quite simple to define:

def last(a_list):
    return a_list[-1]

def first(a_list):
    return a_list[0]

Or use operator.itemgetter:

>>> import operator
>>> last = operator.itemgetter(-1)
>>> first = operator.itemgetter(0)

In either case:

>>> last(a_list)
'three'
>>> first(a_list)
'zero'

Special cases

If you're doing something more complicated, you may find it more performant to get the last element in slightly different ways.

If you're new to programming, you should avoid this section, because it couples otherwise semantically different parts of algorithms together. If you change your algorithm in one place, it may have an unintended impact on another line of code.

I try to provide caveats and conditions as completely as I can, but I may have missed something. Please comment if you think I'm leaving a caveat out.

Slicing

A slice of a list returns a new list - so we can slice from -1 to the end if we are going to want the element in a new list:

>>> a_slice = a_list[-1:]
>>> a_slice
['three']

This has the upside of not failing if the list is empty:

>>> empty_list = []
>>> tail = empty_list[-1:]
>>> if tail:
...     do_something(tail)

Whereas attempting to access by index raises an IndexError which would need to be handled:

>>> empty_list[-1]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: list index out of range

But again, slicing for this purpose should only be done if you need:

• a new list created
• and the new list to be empty if the prior list was empty.

for loops

As a feature of Python, there is no inner scoping in a for loop.

If you're performing a complete iteration over the list already, the last element will still be referenced by the variable name assigned in the loop:

>>> def do_something(arg): pass
>>> for item in a_list:
...     do_something(item)
...     
>>> item
'three'

This is not semantically the last thing in the list. This is semantically the last thing that the name, item, was bound to.

>>> def do_something(arg): raise Exception
>>> for item in a_list:
...     do_something(item)
...
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "<stdin>", line 1, in do_something
Exception
>>> item
'zero'

Thus this should only be used to get the last element if you

• are already looping, and
• you know the loop will finish (not break or exit due to errors), otherwise it will point to the last element referenced by the loop.

Getting and removing it

We can also mutate our original list by removing and returning the last element:

>>> a_list.pop(-1)
'three'
>>> a_list
['zero', 'one', 'two']

But now the original list is modified.

(-1 is actually the default argument, so list.pop can be used without an index argument):

>>> a_list.pop()
'two'

Only do this if

• you know the list has elements in it, or are prepared to handle the exception if it is empty, and
• you do intend to remove the last element from the list, treating it like a stack.

These are valid use-cases, but not very common.

Saving the rest of the reverse for later:

I don't know why you'd do it, but for completeness, since reversed returns an iterator (which supports the iterator protocol) you can pass its result to next:

>>> next(reversed([1,2,3]))
3

So it's like doing the reverse of this:

>>> next(iter([1,2,3]))
1

But I can't think of a good reason to do this, unless you'll need the rest of the reverse iterator later, which would probably look more like this:

reverse_iterator = reversed([1,2,3])
last_element = next(reverse_iterator)

use_later = list(reverse_iterator)

and now:

>>> use_later
[2, 1]
>>> last_element
3

var totop = $('#totop');
totop.click(function(){
 $('html, body').stop(true,true).animate({scrollTop:0}, 1000);
 return false;
});

$(window).scroll(function(){
 if ($(this).scrollTop() > 100){ 
  totop.fadeIn();
 }else{
  totop.fadeOut();
 }
});

<img id="totop" src="img/arrow_up.png" title="Click to go Up" style="display:none;position:fixed;bottom:10px;right:10px;cursor:pointer;cursor:hand;"/>

This will do:

/^(apple|banana)$/

to exclude from captured strings (e.g. $1,$2):

(?:apple|banana)

This is best plugin with proper documentation and examples

Plus point: you can ask for help in its discussion forum and you will get response within a day from the author itself, really impressive.

Use this function: http://br.php.net/json_decode This will automatically create PHP arrays.

Use

rm -rf *

Update: The . stands for current directory, but we cannot use this. The command seems to have explicit checks for . and ... Use the wildcard globbing instead. But this can be risky.

A safer version IMO is to use:

rm -ri * 

(this prompts you for confirmation before deleting every file/directory.)

I've created an NPM module, which allows you to share locally-stored data across domains: https://www.npmjs.com/package/cookie-toss

By using an iframe hosted on Domain A, you can store all of your user data on Domain A, and reference that data by posting requests to the Domain A iframe.

Thus, Domains B, C, etc. can inject the iframe and post requests to it to store and access the desired data. Domain A becomes the hub for all shared data.

With a domain whitelist inside of Domain A, you can ensure only your dependent sites can access the data on Domain A.

The trick is to have the code inside of the iframe on Domain A which is able to recognize which data is being requested. The README in the above NPM module goes more in depth into the procedure.

Hope this helps!

See this link. It shows you how to dynamically create variables in PowerShell.

Here is the basic idea:

Use New-Variable and Get-Variable,

for ($i=1; $i -le 5; $i++)
{
    New-Variable -Name "var$i" -Value $i
    Get-Variable -Name "var$i" -ValueOnly
}

(It is taken from the link provided, and I don't take credit for the code.)

DESCRIBE FORMATTED my_table;

or

DESCRIBE FORMATTED my_table PARTITION (my_column='my_value');

This problem is caused (as others have stated) by model attributes being persisted into the query string - this is usually undesirable and is at risk of creating security holes as well as ridiculous query strings. My usual solution is to never use Strings for redirects in Spring MVC, instead use a RedirectView which can be configured not to expose model attributes (see: http://static.springsource.org/spring/docs/3.1.x/javadoc-api/org/springframework/web/servlet/view/RedirectView.html)

RedirectView(String url, boolean contextRelative, boolean http10Compatible, boolean exposeModelAttributes)

So I tend to have a util method which does a 'safe redirect' like:

public static RedirectView safeRedirect(String url) {
    RedirectView rv = new RedirectView(url);
    rv.setExposeModelAttributes(false);
    return rv;
}

The other option is to use bean configuration XML:

<bean id="myBean" class="org.springframework.web.servlet.view.RedirectView">
   <property name="exposeModelAttributes" value="false" />
   <property name="url" value="/myRedirect"/>
</bean>

Again, you could abstract this into its own class to avoid repetition (e.g. SafeRedirectView).

A note about 'clearing the model' - this is not the same as 'not exposing the model' in all circumstances. One site I worked on had a lot of filters which added things to the model, this meant that clearing the model before redirecting would not prevent a long query string. I would also suggest that 'not exposing model attributes' is a more semantic approach than 'clearing the model before redirecting'.

I had to add the .classpath too, form a java project. I made a dummy java project and looked in the workspace for this dummy java project to see what is required. I transferred the two files. profile and .claspath to my checked out, and disconnected source from my subversion server. From then on it turned to a java project from just a plain old project.

For version 2.6 and up, the dialog is in the "Preferences" dialog, access using Cmd ',':

PyCharm (far left menu) -> Preferences... -> Editor (bottom left section) -> Appearance -> Show line numbers checkbox

Simply add static in the declaration of these two methods and the compile time error will disappear!

By default in C# methods are instance methods, and they receive the implicit "self" argument. By making them static, no such argument is needed (nor available), and the method must then of course refrain from accessing any instance (non-static) objects or methods of the class.

More info on static methods
Provided the class and the method's access modifiers (public vs. private) are ok, a static method can then be called from anywhere without having to previously instantiate a instance of the class. In other words static methods are used with the following syntax:

    className.classMethod(arguments)
rather than
    someInstanceVariable.classMethod(arguments)

A classical example of static methods are found in the System.Math class, whereby we can call a bunch of these methods like

   Math.Sqrt(2)
   Math.Cos(Math.PI)

without ever instantiating a "Math" class (in fact I don't even know if such an instance is possible)

I think this may help:

Secondly, you need to be aware that the checked attribute RETURNS a string "true", "false"
Why is this important? Because you need to use the correct Type. A string, not a boolean. This also important when parsing your checkbox.
$('mycheckbox')[0].checked = "true"

if($('mycheckbox')[0].checked === "true"){ //do something }

You also need to realize that the "checked" ATTRIBUTE is for setting the value of the checkbox initially. This doesn't do much once the element is rendered to the DOM. Picture this working when the webpage loads and is initially parsed.
I'll go with IE's preference on this one: <input type="checkbox" checked="checked"/>

Lastly, the main aspect of confusion for a checkbox is that the checkbox UI element is not the same as the element's property value. They do not correlate directly. If you work in .net, you'll discover that the user "checking" a checkbox never reflects the actual bool value passed to the controller. To set the UI, I use both $('mycheckbox').val(true); and $('mycheckbox').attr('checked', 'checked');

UPDATE

"Run as Aministrator" is just a command, enabling the program to continue some operations that require the Administrator privileges, without displaying the UAC alerts.

Even if your user is a member of administrators group, some applications like yours need the Administrator privileges to continue running, because the application is considered not safe, if it is doing some special operation, like editing a system file or something else. This is the reason why Windows needs the Administrator privilege to execute the application and it notifies you with a UAC alert. Not all applications need an Amnistrator account to run, and some applications, like yours, need the Administrator privileges.

If you execute the application with 'run as administrator' command, you are notifying the system that your application is safe and doing something that requires the administrator privileges, with your confirm.

If you want to avoid this, just disable the UAC on Control Panel.

If you want to go further, read the question Difference between "Run as Administrator" and Windows 7 Administrators Group on Microsoft forum or this SuperUser question.

If your merge was not too complicated another option would be to:

1. Move all the changes including the merge changes back to stash using "git stash"
2. Run the merge again and commit your changes (without the changes from the dropped stash)
3. Run a "git stash pop" which should ignore all the changes from your previous merge since the files are identical now.

After that you are left with only the changes from the stash you dropped too early.

string baseUrl = Request.Url.GetLeftPart(UriPartial.Authority)

That's it ;)

This solution supports querystrings!

var Url = require('url');
var Path = require('path');

var url = 'http://i.imgur.com/Mvv4bx8.jpg?querystring=true';
var result = Path.extname(Url.parse(url).pathname); // '.jpg'

A few comments:

1. Since the search position is important you should specify where you start the search. I use ws.[a1] and xlNext below so my search starts in A2 of the specified sheet.
2. Some of Finds arguments - including lookat use the prior search settings. So you should always specify xlWhole or xlPart to match all or part a string respectively.
3. You can do all you want - including inserting a row, and prompting the user for a new value (my code will suggest 20 if the prior value was 19) without using Select or Activate

suggested code

Sub FindEm()
Dim Wb As Workbook
Dim ws As Worksheet
Dim rng1 As Range
Set Wb = ThisWorkbook
Set ws = Wb.Sheets("ECM Overview")
Set rng1 = ws.Range("A:A").Find("ProjTemp", ws.[a1], xlValues, xlWhole, , xlNext)
If Not rng1 Is Nothing Then
rng1.EntireRow.Insert
rng1.Offset(-1, 0).Value = Application.InputBox("Please enter data", "User Data Entry", rng1.Offset(-2, 0) + 1, , , , , 1)
Else
MsgBox "ProjTemp not found", vbCritical
End If
End Sub

The second one would be preferred:

• it avoids unnecessary/inefficient constructor calls
• it makes you specify the element type for the list (if that is missing, you get a warning)

However, having two different types of object in the same list has a bit of a bad design smell. We need more context to speak on that.

CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.

In HTML,

<div id="hideme">
    <audio id="audioTag" controls>
        <source src="/path/to/audio.mp3">
    </audio>
</div>

with JS

<script type="text/javascript">
window.onload = function() {
    var audioEl = document.getElementById("audioTag");
    audioEl.load();
    audioEl.play();
};
</script>

In CSS,

#hideme {display: none;}

Its easy, just wrap it in a relative box like so:

<div class="relative">
 <div class="absolute">LOGO</div>
</div>

The relative box has a margin: 0 Auto; and, important, a width...
