You can do it like this (with a slightly modified array to show it works for non-square arrays):

        long[,] arr = new long[5, 4] { { 1, 2, 3, 4 }, { 1, 1, 1, 1 }, { 2, 2, 2, 2 }, { 3, 3, 3, 3 }, { 4, 4, 4, 4 } };

        int rowLength = arr.GetLength(0);
        int colLength = arr.GetLength(1);

        for (int i = 0; i < rowLength; i++)
        {
            for (int j = 0; j < colLength; j++)
            {
                Console.Write(string.Format("{0} ", arr[i, j]));
            }
            Console.Write(Environment.NewLine + Environment.NewLine);
        }
        Console.ReadLine();

I had the same problem, after loads of research and Googling, I found the following solution worked best for me! plenty of trial and error went into this one.

--- SOLVED / SOLUTION ---

JS

$(document).ready(function() {
            $("header").delay(5000).queue(function(){
                $(this).css({"background-image":"url(<?php bloginfo('template_url') ?>/img/header-boy-hover.jpg)"});
            });
        });

CSS

header {
    -webkit-transition:all 1s ease-in;
    -moz-transition:all 1s ease-in;
    -o-transition:all 1s ease-in;
    -ms-transition:all 1s ease-in;
    transition:all 1s ease-in;
}

This blog explains your problem neatly Async Best Practices.

The gist of it being you shouldn't use void as return for an async method, unless it's an async event handler, this is bad practice because it doesn't allow exceptions to be caught ;-).

Best practice would be to change the return type to Task. Also, try to code async all the way trough, make every async method call and be called from async methods. Except for a Main method in a console, which can't be async (before C# 7.1).

You will run into deadlocks with GUI and ASP.NET applications if you ignore this best practice. The deadlock occurs because these applications runs on a context that allows only one thread and won't relinquish it to the async thread. This means the GUI waits synchronously for a return, while the async method waits for the context: deadlock.

This behaviour won't happen in a console application, because it runs on context with a thread pool. The async method will return on another thread which will be scheduled. This is why a test console app will work, but the same calls will deadlock in other applications...

It's not very clear what the problem is and what you are trying to accomplish from the code you posted, but I'll take a stab at it.

In general, I suggest calling a function on ng-click like so:

<a ng-click="navigateToPath()">click me</a>

obj.val1 & obj.val2 should be available on your controller's $scope, you dont need to pass those into a function from the markup.

then, in your controller:

$scope.navigateToPath = function(){
   var path = '/somePath/' + $scope.obj.val1 + '/' + $scope.obj.val2; //dont need the '#'
   $location.path(path)       
}

Remove this line from your manifest:

<application android:label="@string/app_name" android:icon="@drawable/icon">

You have two application tags only one should be present.

That doesn't work because a member function pointer cannot be handled like a normal function pointer, because it expects a "this" object argument.

Instead you can pass a static member function as follows, which are like normal non-member functions in this regard:

m_cRedundencyManager->Init(&CLoggersInfra::Callback, this);

The function can be defined as follows

static void Callback(int other_arg, void * this_pointer) {
    CLoggersInfra * self = static_cast<CLoggersInfra*>(this_pointer);
    self->RedundencyManagerCallBack(other_arg);
}

setBounds is used to define the bounding rectangle of a component. This includes it's position and size.

The is used in a number of places within the framework.

• It is used by the layout manager's to define the position and size of a component within it's parent container.
• It is used by the paint sub system to define clipping bounds when painting the component.

For the most part, you should never call it. Instead, you should use appropriate layout managers and let them determine the best way to provide information to this method.

You can also use DataTable - you can define then the number of columns and their types and then add rows http://www.dotnetperls.com/datatable

Two options:

libimobiledevice is installable via homebrew and works great. Its idevicesyslog tool works similarly to deviceconsole (below), and it supports wirelessly viewing your device's syslog (!)

I've written more about that on Tumblr tl;dr:

brew install libimobiledevice
idevice_id --list // list available device UDIDs
idevicesyslog -u <device udid>

with the device connected via USB or available on the local wireless network.

(Keeping for the historical record, from 2013:) deviceconsole from rpetrich is a much less wacked-out solution than ideviceconsole above. My fork of it builds and runs in Xcode 5 out of the box, and the Build action will install the binary to /usr/local/bin for ease of use.

As an additional helpful bit of info, I use it in the following style which makes it easy to find the device I want in my shell history and removes unnecessary > lines that deviceconsole prints out.

deviceconsole -d -u <device UDID> | uniq -u && echo "<device name>"

Ubuntu with Nginx and PHP-FPM 7 use this:

sudo apt-get install php-imap

service php7.0-fpm restart service ngnix restart

check the module have been installed php -m | grep imap

Configuration for module imap will be enabled automatically, both at cli php.ini and at fpm php.ini

nano /etc/php/7.0/cli/conf.d/20-imap.ini nano /etc/php/7.0/fpm/conf.d/20-imap.ini

I tried several things, finally what worked for me was to delete (and move to trash) the .xib file in question. Then re-create it. To make things easier, I copied the stuff in the .xib temporarily to another .xib, then copied it back into the newly created one.

Just do:

ng-click="prefs = false"

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

Code For Merging PDF's in Itextsharp

 public static void Merge(List<String> InFiles, String OutFile)
    {

        using (FileStream stream = new FileStream(OutFile, FileMode.Create))
        using (Document doc = new Document())
        using (PdfCopy pdf = new PdfCopy(doc, stream))
        {
            doc.Open();

            PdfReader reader = null;
            PdfImportedPage page = null;

            //fixed typo
            InFiles.ForEach(file =>
            {
                reader = new PdfReader(file);

                for (int i = 0; i < reader.NumberOfPages; i++)
                {
                    page = pdf.GetImportedPage(reader, i + 1);
                    pdf.AddPage(page);
                }

                pdf.FreeReader(reader);
                reader.Close();
                File.Delete(file);
            });
        }

Don't use [[v]*n]*n, it is a trap!

>>> a = [[0]*3]*3
>>> a
[[0, 0, 0], [0, 0, 0], [0, 0, 0]]
>>> a[0][0]=1
>>> a
[[1, 0, 0], [1, 0, 0], [1, 0, 0]]

but

    t = [ [0]*3 for i in range(3)]

works great.

For niche needs when you know your data like your example ... this works :

JSON.parse(this_is_double_quoted);

JSON.parse("House");  // for example

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

I ran into the same issue while using CMB2 with Wordpress and wanted to hook into the change event of a file upload metabox.

So in case you're not able to modify the code that invokes the change (in this case the CMB2 script), use the code below. The trigger is being invoked AFTER the value is set, otherwise your change eventHandler will work, but the value will be the previous one, not the one being set.

Here's the code i use:

(function ($) {
    var originalVal = $.fn.val;
    $.fn.val = function (value) {
        if (arguments.length >= 1) {
            // setter invoked, do processing
            return originalVal.call(this, value).trigger('change');
        }
        //getter invoked do processing
        return originalVal.call(this);
    };
})(jQuery);

Option "Start debugging, Debug + Windows + Modules" does not exist in Microsoft Visual Studio Express 2013 edition.

Unchecking "Use Managed Compatibility Mode" in Tools Options Debugging fixes this.

As Davide Gualano has been told. This one

$("#myDiv").load("myScript.php?var=x&var2=y&var3=z")

use GET method for sending the request, and this one

$("#myDiv").load("myScript.php", {var:x, var2:y, var3:z})

use POST method for sending the request. But any limitation that is applied to each method (post/get) is applied to the alternative usages that has been mentioned in the question.

For example: url length limits the amount of sending data in GET method.

I needed to remove all files in child dirs except for some files. The following worked for me (three patterns specified):

find . -depth -type f -not -name *.itp -and -not -name *ane.gro -and -not -name *.top -exec rm '{}' +

you could also use tig for a nice, ncurses-based git repository browser. To view history of a file:

tig path/to/file

var upload = multer({dest: "./uploads"});
var mongo = require('mongodb');
var Grid = require("gridfs-stream");
Grid.mongo = mongo;

router.post('/:id', upload.array('photos', 200), function(req, res, next){
gfs = Grid(db);
var ss = req.files;
   for(var j=0; j<ss.length; j++){
     var originalName = ss[j].originalname;
     var filename = ss[j].filename;
     var writestream = gfs.createWriteStream({
         filename: originalName
     });
    fs.createReadStream("./uploads/" + filename).pipe(writestream);
   }
});

In your view:

<form action="/" method="post" enctype="multipart/form-data">
<input type="file" name="photos">

With this code you can add single as well as multiple images in MongoDB.

You can access any DGV cell as follows :

dataGridView1.Rows[rowIndex].Cells[columnIndex].Value = value;

But usually it's better to use databinding : you bind the DGV to a data source (DataTable, collection...) through the DataSource property, and only work on the data source itself. The DataGridView will automatically reflect the changes, and changes made on the DataGridView will be reflected on the data source

Here's an efficient option that doesn't use the clipboard.

Sub transposeAndPasteRow(rowToCopy As Range, pasteTarget As Range)
    pasteTarget.Resize(rowToCopy.Columns.Count) = Application.WorksheetFunction.Transpose(rowToCopy.Value)
End Sub

Use it like this.

Sub test()
    Call transposeAndPasteRow(Worksheets("Sheet1").Range("A1:A5"), Worksheets("Sheet2").Range("A1"))
End Sub

Take caution not to overuse the section tag as a replacement for a div element. A section tag should define a significant region within the context of the body. Semantically, HTML5 encourages us to define our document as follows:

<html>_x000D_
<head></head>_x000D_
<body>_x000D_
    <header></header>_x000D_
    <section>_x000D_
        <h1></h1>_x000D_
        <div>_x000D_
            <span></span>_x000D_
        </div>_x000D_
        <div></div>_x000D_
    </section>_x000D_
    <footer></footer>_x000D_
</body>_x000D_
</html>

This strategy allows web robots and automated screen readers to better understand the flow of your content. This markup clearly defines where your major page content is contained. Of course, headers and footers are often common across hundreds if not thousands of pages within a website. The section tag should be limited to explain where the unique content is contained. Within the section tag, we should then continue to markup and control the content with HTML tags which are lower in the hierarchy, like h1, div, span, etc.

In most simple pages, there should only be a single section tag, not multiple ones. Please also consider also that there are other interesting HTML5 tags which are similar to section. Consider using article, summary, aside and others within your document flow. As you can see, these tags further enhance our ability to define the major regions of the HTML document.

A hashmap works like this (this is a little bit simplified, but it illustrates the basic mechanism):

It has a number of "buckets" which it uses to store key-value pairs in. Each bucket has a unique number - that's what identifies the bucket. When you put a key-value pair into the map, the hashmap will look at the hash code of the key, and store the pair in the bucket of which the identifier is the hash code of the key. For example: The hash code of the key is 235 -> the pair is stored in bucket number 235. (Note that one bucket can store more then one key-value pair).

When you lookup a value in the hashmap, by giving it a key, it will first look at the hash code of the key that you gave. The hashmap will then look into the corresponding bucket, and then it will compare the key that you gave with the keys of all pairs in the bucket, by comparing them with equals().

Now you can see how this is very efficient for looking up key-value pairs in a map: by the hash code of the key the hashmap immediately knows in which bucket to look, so that it only has to test against what's in that bucket.

Looking at the above mechanism, you can also see what requirements are necessary on the hashCode() and equals() methods of keys:

• If two keys are the same (equals() returns true when you compare them), their hashCode() method must return the same number. If keys violate this, then keys that are equal might be stored in different buckets, and the hashmap would not be able to find key-value pairs (because it's going to look in the same bucket).

• If two keys are different, then it doesn't matter if their hash codes are the same or not. They will be stored in the same bucket if their hash codes are the same, and in this case, the hashmap will use equals() to tell them apart.

You can remove "JavaAppletPlugin.plugin" found in Spotlight or Finder, then re-install downloaded Java 8.

This will simply solve your problem.

You could just download jq binary for your platform and run (chmod +x jq):

$ curl 'https://twitter.com/users/username.json' | ./jq -r '.name'

It extracts "name" attribute from the json object.

jq homepage says it is like sed for JSON data.

console.log(JSON.stringify(data)) will do what you need. I'm assuming that you're using jQuery based on your code.

If you're wanting those two particular values, you can just access those and pass them to log.

console.log(data.input_data['quantity-row_122']); 
console.log(data.input_data['price-row_122']);

According to MDN, <input type="search" /> is currently supported in all modern browsers:

<input type="search" value="Clear this." />

However, if you want different behavior that is consistent across browsers here are some light-weight alternatives that only require JavaScript:

Option 1 - Always display the 'x': (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
  el.addEventListener('click', function(e) {
    e.target.previousElementSibling.value = '';
  });
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input > [data-clear-input] {
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Always display the 'x':</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Option 2 - Only display the 'x' when hovering over the field: (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
  el.addEventListener('click', function(e) {
    e.target.previousElementSibling.value = '';
  });
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input:hover > [data-clear-input] {
  display: block;
}
.clearable-input > [data-clear-input] {
  display: none;
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Only display the 'x' when hovering over the field:</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Option 3 - Only display the 'x' if the input element has a value: (example here)

Array.prototype.forEach.call(document.querySelectorAll('.clearable-input'), function(el) {
  var input = el.querySelector('input');

  conditionallyHideClearIcon();
  input.addEventListener('input', conditionallyHideClearIcon);
  el.querySelector('[data-clear-input]').addEventListener('click', function(e) {
    input.value = '';
    conditionallyHideClearIcon();
  });

  function conditionallyHideClearIcon(e) {
    var target = (e && e.target) || input;
    target.nextElementSibling.style.display = target.value ? 'block' : 'none';
  }
});

.clearable-input {
  position: relative;
  display: inline-block;
}
.clearable-input > input {
  padding-right: 1.4em;
}
.clearable-input >[data-clear-input] {
  display: none;
  position: absolute;
  top: 0;
  right: 0;
  font-weight: bold;
  font-size: 1.4em;
  padding: 0 0.2em;
  line-height: 1em;
  cursor: pointer;
}
.clearable-input > input::-ms-clear {
  display: none;
}

<p>Only display the 'x' if the `input` element has a value:</p>

<div class="clearable-input">
  <input type="text" />
  <span data-clear-input>&times;</span>
</div>

<div class="clearable-input">
  <input type="text" value="Clear this." />
  <span data-clear-input>&times;</span>
</div>

Yes - you can create encapsulated property, but it's not been done with access modifiers (public|private) at least not with ES6.

Here is a simple example how it can be done with ES6:

1 Create class using class word

2 Inside it's constructor declare block-scoped variable using let OR const reserved words -> since they are block-scope they cannot be accessed from outside (encapsulated)

3 To allow some access control (setters|getters) to those variables you can declare instance method inside it's constructor using: this.methodName=function(){} syntax

"use strict";
    class Something{
        constructor(){
            //private property
            let property="test";
            //private final (immutable) property
            const property2="test2";
            //public getter
            this.getProperty2=function(){
                return property2;
            }
            //public getter
            this.getProperty=function(){
                return property;
            }
            //public setter
            this.setProperty=function(prop){
                property=prop;
            }
        }
    }

Now lets check it:

var s=new Something();
    console.log(typeof s.property);//undefined 
    s.setProperty("another");//set to encapsulated `property`
    console.log(s.getProperty());//get encapsulated `property` value
    console.log(s.getProperty2());//get encapsulated immutable `property2` value

You can use:

objects_all=Class.objects.filter(filter_condition="")

This will return a query set even if it gets one object. If you need exactly one object use:

obj=Class.objects.get(conditon="")

Under the connection properties, uncheck "Enable background refresh". This will make the connection refresh when told to, not in the background as other processes happen.

With background refresh disabled, your VBA procedure will wait for your external data to refresh before moving to the next line of code.

Then you just modify the following code:

ActiveWorkbook.Connections("CONNECTION_NAME").Refresh
Sheets("SHEET_NAME").PivotTables("PIVOT_TABLE_NAME").PivotCache.Refresh

You can also turn off background refresh in VBA:

ActiveWorkbook.Connections("CONNECTION_NAME").ODBCConnection.BackgroundQuery = False

In my case, restarting SQL Server Service was enough to resolve the issue.

Generally you should watch out for deeply nested objects in React state. To avoid unexpected behavior, the state should be updated immutably. When you have deep objects, you end up deep cloning them for immutability, which can be quite expensive in React. Why?

Once you deep clone the state, React will recalculate and re-render everything that depends on the variables, even though they haven't changed!

So, before trying to solve your issue, think how you can flatten the state first. As soon as you do that, you will find beautiful tools that will help dealing with large states, such as useReducer().

In case you thought about it, but are still convinced you need to use a deeply nested state tree, you can still use useState() with libraries like immutable.js and Immutability-helper. They make it simple to update or clone deep objects without having to worry about mutability.

The #include directive literally means "copy all the data in that file to this spot." So when you include the header file, it's textually within the code file, and everything in it will be there, give or take the effect of other directives or macro replacements, when the code file (now called the compilation unit or translation unit) is handed off from the preprocessor module to the compiler module.

Which means the declaration and definition of your static member function were really in the same file all along...

EventHandler handler = (s, e) => MessageBox.Show("Woho");

button.Click += handler;
button.Click -= handler;

Before running the unit tests, just remove the runtime tags from app.config file. Problem will be solved.

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

This feature helps not only delaying expensive calculations, but is also useful to construct mutual dependent or cyclic structures. E.g. this leads to an stack overflow:

trait Foo { val foo: Foo }
case class Fee extends Foo { val foo = Faa() }
case class Faa extends Foo { val foo = Fee() }

println(Fee().foo)
//StackOverflowException

But with lazy vals it works fine

trait Foo { val foo: Foo }
case class Fee extends Foo { lazy val foo = Faa() }
case class Faa extends Foo { lazy val foo = Fee() }

println(Fee().foo)
//Faa()

I recommend using passthru and handling the output buffer directly:

ob_start();
passthru('/usr/bin/python2.7 /srv/http/assets/py/switch.py arg1 arg2');
$output = ob_get_clean(); 

You could also disable the cascade delete convention in global scope of your application by doing this:

modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>()

I had a similar issue, also seeing "Failed to load resource: net::ERR_CONTENT_DECODING_FAILED" and "ILLEGAL TOKEN" errors when loading JS files locally. Pressing CTRL+SHIFT+DEL and deleting all "Cookies and other site and plugin data" and "Cached images and files" fixed it.

>>> str(datetime.timedelta(hours=10.56))
10:33:36

>>> td = datetime.timedelta(hours=10.505) # any timedelta object
>>> ':'.join(str(td).split(':')[:2])
10:30

Passing the timedelta object to the str() function calls the same formatting code used if we simply type print td. Since you don't want the seconds, we can split the string by colons (3 parts) and put it back together with only the first 2 parts.

You have to add the reference of the namespace : System.Windows.Forms to your project, because for some reason it is not already added, so you can add New Reference from Visual Studio menu.

Right click on "Reference" ? "Add New Reference" ? "System.Windows.Forms"

Probably the exact details of em.flush() are implementation-dependent. In general anyway, JPA providers like Hibernate can cache the SQL instructions they are supposed to send to the database, often until you actually commit the transaction. For example, you call em.persist(), Hibernate remembers it has to make a database INSERT, but does not actually execute the instruction until you commit the transaction. Afaik, this is mainly done for performance reasons.

In some cases anyway you want the SQL instructions to be executed immediately; generally when you need the result of some side effects, like an autogenerated key, or a database trigger.

What em.flush() does is to empty the internal SQL instructions cache, and execute it immediately to the database.

Bottom line: no harm is done, only you could have a (minor) performance hit since you are overriding the JPA provider decisions as regards the best timing to send SQL instructions to the database.

There are very nice Emoji icons instructions available at

• https://gist.github.com/rxaviers/7360908
• or at https://github.com/StylishThemes/GitHub-Dark/wiki/Emoji

You can check them out. I hope you would find suitable icons for your writing.

Best,

Single line- There are two ways, you can simply change.

1- Pragmatically (Swift 3)

Just add the following code

    yourLabel.numberOfLines = 1;
    yourLabel.minimumScaleFactor = 0.7;
    yourLabel.adjustsFontSizeToFitWidth = true;

2 - Using UILabel Attributes inspector

i- Select your label- Set number of lines 1.
ii- Autoshrink-  Select Minimum Font Scale from drop down
iii- Set Minimum Font Scale value as you wish , I have set 0.7 as in below image. (default is 0.5)

I have come accross this problem today on AWS Lambda. I created an environment variable RANDFILE = /tmp/.random

That did the trick.

SQL (or to be more precise, the RDBMS) is not meant to be the right choice for formatting the output. The database should deliver raw data which then should be formatted (or more general: processed) in the destination application.

However, depending on the specific system you use, you may write a UDF (user defined function) to achive what you want. But please bear in mind that you then are in fact returning a varchar, which you will not be able to further process (e.g. summarize).

 $qb = $this->getDoctrine()->getManager()->createQueryBuilder();  
 $qb->select('p') ->from('Pandora\UserBundle\Entity\PhoneNumber', 'p');
$qb->where('p.number = :number');
$qb->OrWhere('p.validatedNumber=:number');
$qb->setMaxResults(1);
$qb->setParameter('number',$postParams['From'] );
$result = $qb->getQuery()->getResult();
 $data=$result[0];

I have to write a whole answer separately since it's hard to add a comment so long to the second answer.

I'm sorry to say this, but the second answer above doesn't work right.

The following three scenarios will show my point:

Scenario 1: Before the following way was deprecated,

  $(window).load(function () {
     alert("Window Loaded.");
  });

if we execute the following two queries:

<script>
   $(window).load(function () {
     alert("Window Loaded.");
   }); 

   $(document).ready(function() {
     alert("Dom Loaded.");
   });
</script>,

the alert (Dom Loaded.) from the second query will show first, and the one (Window Loaded.) from the first query will show later, which is the way it should be.

Scenario 2: But if we execute the following two queries like the second answer above suggests:

<script>
   $(window).ready(function () {
     alert("Window Loaded.");
   }); 

   $(document).ready(function() {
     alert("Dom Loaded.");
   });
</script>,

the alert (Window Loaded.) from the first query will show first, and the one (Dom Loaded.) from the second query will show later, which is NOT right.

Scenario 3: On the other hand, if we execute the following two queries, we'll get the correct result:

<script>
   $(window).on("load", function () {
     alert("Window Loaded.");
   }); 

   $(document).ready(function() {
     alert("Dom Loaded.");
   });
</script>,

that is to say, the alert (Dom Loaded.) from the second query will show first, and the one (Window Loaded.) from the first query will show later, which is the RIGHT result.

In short, the FIRST answer is the CORRECT one:

$(window).on('load', function () {
  alert("Window Loaded.");
});

All the radio buttons options must have the same name for you to be able to select one option at a time.

I just had the same problem and it was because I moved the project location and simply needed to recreate the virtual directory.

try {

    Intent intent = new Intent("com.google.zxing.client.android.SCAN");
    intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); // "PRODUCT_MODE for bar codes

    startActivityForResult(intent, 0);

} catch (Exception e) {

    Uri marketUri = Uri.parse("market://details?id=com.google.zxing.client.android");
    Intent marketIntent = new Intent(Intent.ACTION_VIEW,marketUri);
    startActivity(marketIntent);

}

and in onActivityResult():

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {           
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 0) {

        if (resultCode == RESULT_OK) {
            String contents = data.getStringExtra("SCAN_RESULT");
        }
        if(resultCode == RESULT_CANCELED){
            //handle cancel
        }
    }
}

Most browsers don't fully support the numerical values for font-weight. Here's a good article about the problem, and even tough it's a little old, it does seem to be correct.

If you need something bolder then you might want to try using a different font that's bolder than your existing one. Naturally, you could probably adjust the font size for a similar effect.

After trying the filter approach without success (it did for some reason not enter the doFilter() function) I changed my setup a bit and found a very simple solution for the root serving problem:

Instead of serving " / * " in my main Servlet, I now only listen to dedicated language prefixes "EN", "EN/ *", "DE", "DE/ *"

Static content gets served by the default Servlet and the empty root requests go to the index.jsp which calls up my main Servlet with the default language:

< jsp:include page="/EN/" /> (no other content on the index page.)

The point for diamond operator is simply to reduce typing of code when declaring generic types. It doesn't have any effect on runtime whatsoever.

The only difference if you specify in Java 5 and 6,

List<String> list = new ArrayList();

is that you have to specify @SuppressWarnings("unchecked") to the list (otherwise you will get an unchecked cast warning). My understanding is that diamond operator is trying to make development easier. It's got nothing to do on runtime execution of generics at all.

Depending on the structure of your lists there are some tidyverse options that work nicely with unequal length lists:

l <- list(a = list(var.1 = 1, var.2 = 2, var.3 = 3)
        , b = list(var.1 = 4, var.2 = 5)
        , c = list(var.1 = 7, var.3 = 9)
        , d = list(var.1 = 10, var.2 = 11, var.3 = NA))

df <- dplyr::bind_rows(l)
df <- purrr::map_df(l, dplyr::bind_rows)
df <- purrr::map_df(l, ~.x)

# all create the same data frame:
# A tibble: 4 x 3
  var.1 var.2 var.3
  <dbl> <dbl> <dbl>
1     1     2     3
2     4     5    NA
3     7    NA     9
4    10    11    NA

You can also mix vectors and data frames:

library(dplyr)
bind_rows(
  list(a = 1, b = 2),
  data_frame(a = 3:4, b = 5:6),
  c(a = 7)
)

# A tibble: 4 x 2
      a     b
  <dbl> <dbl>
1     1     2
2     3     5
3     4     6
4     7    NA

You can add whatever headers you need to the HttpClient.

Here is a nice tutorial about it.

This doesn't just reference to POST-requests, you can also use it for GET-requests.

You are populating your dictionaries with references to a single list so when you update it, the update is reflected across all the references. Try a dictionary comprehension instead. See Create a dictionary with list comprehension in Python

d = {k : v for k in blah blah blah}

Old Thread, But in VS 2015 Console.WriteLine does not Write to Output Window If "Enable the Visual Studio Hosting Process" does not Checked or its Disabled in Project Properties -> Debug tab

Radrails 3 is supposed to have it, Aptana Studio 3 will have it. Radrails is in beta, so thats kind of a downer, but none the less it is there to give'r a whirl.

It is multi-platform too, for those of us non-Windoze fellas.

Yes, using Cookies. But be careful, don't put too much in them (I think there is a limit at 4kb). But a few variables are ok.

If you need to store considerably more than that, check out @Annie's great tips in the other answer. For small time data storage, I would say Cookies are the easiest thing.

Note that cookies are stored client side.

The most likely explanation is that either a file called 'pandas.py' is in the same directory as your script, or that another variable called 'pd' is used in your program.

Since Silverlight doesn't support the MidpointRounding option you have to write your own. Something like:

public double RoundCorrect(double d, int decimals)
{
    double multiplier = Math.Pow(10, decimals);

    if (d < 0)
        multiplier *= -1;

    return Math.Floor((d * multiplier) + 0.5) / multiplier;

}

For the examples including how to use this as an extension see the post: .NET and Silverlight Rounding

I'm not 100% sure that I understand your question, so tell me if I'm wrong.

If I got it right, you are reading jbytes that are technically signed chars, but really pixel values ranging from 0 to 255, and you're wondering how you should handle them without corrupting the values in the process.

Then, you should do the following:

• convert jbytes to unsigned char before doing anything else, this will definetly restore the pixel values you are trying to manipulate

• use a larger signed integer type, such as int while doing intermediate calculations, this to make sure that over- and underflows can be detected and dealt with (in particular, not casting to a signed type could force to compiler to promote every type to an unsigned type in which case you wouldn't be able to detect underflows later on)

• when assigning back to a jbyte, you'll want to clamp your value to the 0-255 range, convert to unsigned char and then convert again to signed char: I'm not certain the first conversion is strictly necessary, but you just can't be wrong if you do both

For example:

inline int fromJByte(jbyte pixel) {
    // cast to unsigned char re-interprets values as 0-255
    // cast to int will make intermediate calculations safer
    return static_cast<int>(static_cast<unsigned char>(pixel));
}

inline jbyte fromInt(int pixel) {
    if(pixel < 0)
        pixel = 0;

    if(pixel > 255)
        pixel = 255;

    return static_cast<jbyte>(static_cast<unsigned char>(pixel));
}

jbyte in = ...
int intermediate = fromJByte(in) + 30;
jbyte out = fromInt(intermediate);

Just to add that tmux scroll buffer does not clear with clear, reset or printf. You need to :clear-history. See link.

You can tell SQL Server to use Monday as the start of the week using DATEFIRST like this:

SET DATEFIRST 1

Correct

You can use strtotime() to achieve this:

$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', strtotime($now))); // $now + 3 hours

Have you tried rebooting since you set the environment variable?

It appears that Windows keeps it's environment variable in some sort of cache, and rebooting is one method to refresh it. I'm not sure but there may be a different method, but if you are not going to be changing your variable value too often this may be good enough.

maybe this one can help, you, that's how I did for my website, it works like a charm :

$protocol = $_SERVER["HTTP_CF_VISITOR"];

if (!strstr($protocol, 'https')){
    header("Location: https://" . $_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"]);
    exit();
}

You're trying to jam a square peg in a round hole.

Razor was intended as an HTML-generating template language. You may very well get it to generate JavaScript code, but it wasn't designed for that.

For instance: What if Model.Title contains an apostrophe? That would break your JavaScript code, and Razor won't escape it correctly by default.

It would probably be more appropriate to use a String generator in a helper function. There will likely be fewer unintended consequences of that approach.

I was trying to publish my own package and then include it in another project. I had that issue because of how I've built the first module. Im using ES2015 export to create the module, e.g lets say the module looks like that:

export default function(who = 'world'){
    return `Hello ${who}`;
}

After compiled with Babel and before been published:

'use strict';

Object.defineProperty(exports, "__esModule", {
    value: true
});

exports.default = function () {
    var who = arguments.length <= 0 || arguments[0] === undefined ? 'world' : arguments[0];


    return 'Hello ' + who;
};

So after npm install module-name in another project (none ES2015) i had to do

var hello = require('module-name').default;

To actually got the package imported.

Hope that helps!

Your problem is probably that a elements are display: inline by nature. You can't set the width and height of inline elements.

You would have to set display: block on the a, but that will bring other problems because the links start behaving like block elements. The most common cure to that is giving them float: left so they line up side by side anyway.

getElementsByClassName is a function on the DOM Document. It is neither a jQuery nor a jqLite function.

Don't add the period before the class name when using it:

var result = document.getElementsByClassName("multi-files");

Wrap it in jqLite (or jQuery if jQuery is loaded before Angular):

var wrappedResult = angular.element(result);

If you want to select from the element in a directive's link function you need to access the DOM reference instead of the the jqLite reference - element[0] instead of element:

link: function (scope, element, attrs) {

  var elementResult = element[0].getElementsByClassName('multi-files');
}

Alternatively you can use the document.querySelector function (need the period here if selecting by class):

var queryResult = element[0].querySelector('.multi-files');
var wrappedQueryResult = angular.element(queryResult);

I tried @Aaron's solution and it didn't quite work for me, because it would re-add my keys every time I opened a new tab in my terminal. So I modified it a bit(note that most of my keys are also password-protected so I can't just send the output to /dev/null):

added_keys=`ssh-add -l`

if [ ! $(echo $added_keys | grep -o -e my_key) ]; then
    ssh-add "$HOME/.ssh/my_key"
fi

What this does is that it checks the output of ssh-add -l(which lists all keys that have been added) for a specific key and if it doesn't find it, then it adds it with ssh-add.

Now the first time I open my terminal I'm asked for the passwords for my private keys and I'm not asked again until I reboot(or logout - I haven't checked) my computer.

Since I have a bunch of keys I store the output of ssh-add -l in a variable to improve performance(at least I guess it improves performance :) )

PS: I'm on linux and this code went to my ~/.bashrc file - if you are on Mac OS X, then I assume you should add it to .zshrc or .profile

EDIT: As pointed out by @Aaron in the comments, the .zshrc file is used from the zsh shell - so if you're not using that(if you're not sure, then most likely, you're using bash instead), this code should go to your .bashrc file.

I would suggest using whatever date/time functions/libraries your language/framework of choice provides. Also check out string formatting functions as they often provide easy ways to pass date/timestamps and output a human readable string format.

Use:

#include <iostream>

...

std::cout << std::hex << a;

There are many other options to control the exact formatting of the output number, such as leading zeros and upper/lower case.

I really like the philosophy of the ezSQL database library, which wraps the native SQL methods in an easier-to-use interface.

Fetching a single value from the database is trivial:

  $id = $db->get_var("SELECT id FROM games WHERE ...");

It also makes it easy to fetch a single row, column, or set of rows.

This one get everything between the "." characters. Please note this won't work for more complex URLs like "www.somesite.co.uk" Ideally the function would check for how many instances of the "." character and choose the substring accordingly.

CREATE FUNCTION dbo.GetURL (@URL VARCHAR(250))
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @Work VARCHAR(250)

    SET @Work = @URL

    SET @Work = SUBSTRING(@work, CHARINDEX('.', @work) + 1, LEN(@work))   
    SET @Work = SUBSTRING(@work, 0, CHARINDEX('.', @work))

    --Alternate:
    --SET @Work = SUBSTRING(@work, CHARINDEX('.', @work) + 1, CHARINDEX('.', @work) + 1)   

    RETURN @work
END

Like this:

#include <string>
#include <vector>

struct user
{
    std::string username;
    std::vector<unsigned char> userpassword;
};

int main()
{
    user r;   // r.username is "" and r.userpassword is empty
    // ...
}

Just specifying the uri endpoint worked for me, bower 1.3.9

  "dependencies": {
    "jquery.cookie": "latest",
    "everestjs": "http://www.everestjs.net/static/st.v2.js"
  }

Running bower install, I received following output:

bower new           version for http://www.everestjs.net/static/st.v2.js#*
bower resolve       http://www.everestjs.net/static/st.v2.js#*
bower download      http://www.everestjs.net/static/st.v2.js

You could also try updating bower

• npm update -g bower

According to documentation: the following types of urls are supported:

http://example.com/script.js
http://example.com/style.css
http://example.com/package.zip (contents will be extracted)
http://example.com/package.tar (contents will be extracted)

Well, this largely depends on how you're loading the elements needed in the 'intensive call', my initial thought is that you're doing those loads via ajax. If that's the case, then you could use the 'beforeSend' option and make an ajax call like this:

$.ajax({
  type: 'GET',
  url: "some.php",
  data: "name=John&location=Boston",

  beforeSend: function(xhr){           <---- use this option here
     $('.select_element_you_want_to_load_into').html('Loading...');
  },

  success: function(msg){
     $('.select_element_you_want_to_load_into').html(msg);
  }
});

EDIT I see, in that case, using one of the 'display:block'/'display:none' options above in conjunction with $(document).ready(...) from jQuery is probably the way to go. The $(document).ready() function waits for the entire document structure to be loaded before executing (but it doesn't wait for all media to load). You'd do something like this:

$(document).ready( function() {
  $('table#with_slow_data').show();
  $('div#loading image or text').hide();
});

It's convenient to define a macro for get current timestamp

class Constant {
    struct Time {
        let now = { round(NSDate().timeIntervalSince1970) } // seconds
    }
} 

Then you can use let timestamp = Constant.Time.now()

if it crashes on the delete line then you have almost certainly somehow corrupted the heap. We would need to see more code to diagnose the problem since the example you presented has no errors.

Perhaps you have a buffer overflow on the heap which corrupted the heap structures or even something as simple as a "double free" (or in the c++ case "double delete").

Also, as The Fuzz noted, you may have an error in your destructor as well.

And yes, it is completely normal and expected for delete to invoke the destructor, that is in fact one of its two purposes (call destructor then free memory).

I modified Nico's code to work for my needs.

$.fn.textWidth = function(){
    var self = $(this),
        children = self.contents(),
        calculator = $('<span style="white-space:nowrap;" />'),
        width;

    children.wrap(calculator);
    width = children.parent().width(); // parent = the calculator wrapper
    children.unwrap();
    return width;
};

I'm using .contents() as .children() does not return text nodes which I needed. I also found that the returned width was impacted by the viewport width which was causing wrapping so I'm using white-space:nowrap; to get the correct width regardless of viewport width.

You can use the .forEach() method of JavaScript for looping through JSON.

var datesBooking = [_x000D_
    {"date": "04\/24\/2018"},_x000D_
      {"date": "04\/25\/2018"}_x000D_
    ];_x000D_
    _x000D_
    datesBooking.forEach(function(data, index) {_x000D_
      console.log(data);_x000D_
    });

Swift 2.0

func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?){
    if let error = error{
        print("Error: \(error)")
    }else{
        //NO Error
        //------------------------------------------------
        var feedbackMsg = ""

        switch result.rawValue {
        case MFMailComposeResultCancelled.rawValue:
            feedbackMsg = "Mail Cancelled"
        case MFMailComposeResultSaved.rawValue:
            feedbackMsg = "Mail Saved"
        case MFMailComposeResultSent.rawValue:
            feedbackMsg = "Mail Sent"
        case MFMailComposeResultFailed.rawValue:
            feedbackMsg = "Mail Failed"
        default:
            feedbackMsg = ""
        }

        print("Mail: \(feedbackMsg)")

        //------------------------------------------------
    }
}

You may already know that putting your Button inside of a ToolBar gives you this behavior, but if you want something that will work across ALL current themes with any sort of predictability, you'll need to create a new ControlTemplate.

Prashant's solution does not work with a Button not in a toolbar when the Button has focus. It also doesn't work 100% with the default theme in XP -- you can still see faint gray borders when your container Background is white.

Unfortunately, there is no cross-browser support for opening a confirmation dialog that is not the default OK/Cancel pair. The solution you provided uses VBScript, which is only available in IE.

I would suggest using a Javascript library that can build a DOM-based dialog instead. Try Jquery UI: http://jqueryui.com/

PermGen Space stands for memory allocation for Permanent generation All Java immutable objects come under this category, like String which is created with literals or with String.intern() methods and for loading the classes into memory. PermGen Space speeds up our String equality searching.

The length of an array is available as

int l = array.length;

The size of a List is availabe as

int s = list.size();

I will start with the copy answer of Ben Gripka:

public void Save(string FileName)
{
    using (var writer = new System.IO.StreamWriter(FileName))
    {
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();
    }
}

I used this code earlier. But reality showed that this solution is a bit problematic. Usually most of programmers just serialize setting on save and deserialize settings on load. This is an optimistic scenario. Once the serialization failed, because of some reason, the file is partly written, XML file is not complete and it is invalid. In consequence XML deserialization does not work and your application may crash on start. If the file is not huge, I suggest first serialize object to MemoryStream then write the stream to the File. This case is especially important if there is some complicated custom serialization. You can never test all cases.

public void Save(string fileName)
{
    //first serialize the object to memory stream,
    //in case of exception, the original file is not corrupted
    using (MemoryStream ms = new MemoryStream())
    {
        var writer = new System.IO.StreamWriter(ms);    
        var serializer = new XmlSerializer(this.GetType());
        serializer.Serialize(writer, this);
        writer.Flush();

        //if the serialization succeed, rewrite the file.
        File.WriteAllBytes(fileName, ms.ToArray());
    }
}

The deserialization in real world scenario should count with corrupted serialization file, it happens sometime. Load function provided by Ben Gripka is fine.

public static [ObjectType] Load(string fileName)
{
    using (var stream = System.IO.File.OpenRead(fileName))
    {
        var serializer = new XmlSerializer(typeof([ObjectType]));
        return serializer.Deserialize(stream) as [ObjectType];        
    }    
}

And it could be wrapped by some recovery scenario. It is suitable for settings files or other files which can be deleted in case of problems.

public static [ObjectType] LoadWithRecovery(string fileName)
{
    try
    {
        return Load(fileName);
    }
    catch(Excetion)
    {
        File.Delete(fileName); //delete corrupted settings file
        return GetFactorySettings();
    }
}

What you want can be done quite simply like so:

>>> mystr = input("Please type a sentence: ")
Please type a sentence: abcdE
>>> print(*map(mystr.lower().count, "aeiou"))
1 1 0 0 0
>>>

In case you don't know them, here is a reference on map and one on the *.

Better example is here

 try {
   myDB = this.openOrCreateDatabase("DatabaseName", MODE_PRIVATE, null);

   /* Create a Table in the Database. */
   myDB.execSQL("CREATE TABLE IF NOT EXISTS "
     + TableName
     + " (Field1 VARCHAR, Field2 INT(3));");

   /* Insert data to a Table*/
   myDB.execSQL("INSERT INTO "
     + TableName
     + " (Field1, Field2)"
     + " VALUES ('Saranga', 22);");

   /*retrieve data from database */
   Cursor c = myDB.rawQuery("SELECT * FROM " + TableName , null);

   int Column1 = c.getColumnIndex("Field1");
   int Column2 = c.getColumnIndex("Field2");

   // Check if our result was valid.
   c.moveToFirst();
   if (c != null) {
    // Loop through all Results
    do {
     String Name = c.getString(Column1);
     int Age = c.getInt(Column2);
     Data =Data +Name+"/"+Age+"\n";
    }while(c.moveToNext());
   }

When it comes to Muhammad Mehdi's answer, it is better to do:

private void salary_texbox_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
     Regex regex = new Regex ( "[^0-9]+" );
     if(regex.IsMatch(e.Text))
     {
         MessageBox.Show("Error");
     }
}

Because when comparing with the TextCompositionEventArgs it gets also the last character, while with the textbox.Text it does not. With textbox, the error will show after next inserted character.

Not all parameters are supported by all cameras - actually, they are one of the most troublesome part of the OpenCV library. Each camera type - from android cameras to USB cameras to professional ones offer a different interface to modify its parameters. There are many branches in OpenCV code to support as many of them, but of course not all possibilities are covered.

What you can do is to investigate your camera driver, write a patch for OpenCV and send it to code.opencv.org. This way others will enjoy your work, the same way you enjoy others'.

There is also a possibility that your camera does not support your request - most USB cams are cheap and simple. Maybe that parameter is just not available for modifications.

If you are sure the camera supports a given param (you say the camera manufacturer provides some code) and do not want to mess with OpenCV, you can wrap that sample code in C++ with boost::python, to make it available in Python. Then, enjoy using it.

Use JSON to transfer data types (arrays and objects) between client and server.

In PHP:

• json_encode
• json_decode

In JavaScript:

• JSON.stringify
• JSON.parse

PHP:

echo json_encode($id_numbers);

JavaScript:

id_numbers = JSON.parse(msg);

As Wolfgang mentioned, you can give a fourth parameter to jQuery to automatically decode JSON for you.

id_numbers = new Array();
$.ajax({
    url:"Example.php",
    type:"POST",
    success:function(msg){
        id_numbers = msg;
    },
    dataType:"json"
});

If you are using Express as back-end you just have to install cors and import and use it in app.use(cors());. If it is not resolved then try switching ports. It will surely resolve after switching ports

Also please remember resolutions [quantum of time] are different.

Most windows users won't have that font on their computers. Also, you can't just submit it to your server and call it using font-face because this isn't a free font...

And last, but not least, answering the question that nobody mentioned yet, Helvetica and Helvetica Neue do not render well on screen unless they have a really big font-size. You'll find a lot of pages using this font, and in all of them you'll see that the top border of a line of text looks wavy and that some letters look taller than others. In my opinion this is the main reason why you shouldn't use it. There are other options for you to use, like Open Sans.

you can use send instead of sendFile so you wont face with error! this works will help you!

fs.readFile('public/index1.html',(err,data)=>{
if(err){
  consol.log(err);
}else {
res.setHeader('Content-Type', 'application/pdf');

for telling browser that your response is type of PDF

res.setHeader('Content-Disposition', 'attachment; filename='your_file_name_for_client.pdf');

if you want that file open immediately on the same page after user download it.write 'inline' instead attachment in above code.

__construct() is the method name for the constructor. The constructor is called on an object after it has been created, and is a good place to put initialisation code, etc.

class Person {

    public function __construct() {
        // Code called for each new Person we create
    }

}

$person = new Person();

A constructor can accept parameters in the normal manner, which are passed when the object is created, e.g.

class Person {

    public $name = '';

    public function __construct( $name ) {
        $this->name = $name;
    }

}

$person = new Person( "Joe" );
echo $person->name;

Unlike some other languages (e.g. Java), PHP doesn't support overloading the constructor (that is, having multiple constructors which accept different parameters). You can achieve this effect using static methods.

Note: I retrieved this from the log of the (at time of this writing) accepted answer.

According to a note in the CSS 2.1 spec, the specification “does not fully define the interaction of :before and :after with replaced elements (such as IMG in HTML). This will be defined in more detail in a future specification.” Although input is not really a replaced element any more, the basic situation has not changed: the effect of :before and :after on it in unspecified and generally has no effect.

The solution is to find a different approach to the problem you are trying to address this way. Putting generated content into a text input control would be very misleading: to the user, it would appear to be part of the initial value in the control, but it cannot be modified – so it would appear to be something forced at the start of the control, but yet it would not be submitted as part of form data.

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

I always used a couple lines of code which clear the input stream of any characters and then wait for input to ignore.

Something like:

void pause() {
    cin.clear();
    cout << endl << "Press any key to continue...";
    cin.ignore();
}

And then any time I need it in the program I have my own pause(); function, without the overhead of a system pause. This is only really an issue when writing console programs that you want to stay open or stay fixated on a certain point though.

No. We cannot alter the constraint, only thing we can do is drop and recreate it

ALTER TABLE [TABLENAME] DROP CONSTRAINT [CONSTRAINTNAME]

Foreign Key Constraint

Alter Table Table1 Add Constraint [CONSTRAINTNAME] Foreign Key (Column) References Table2 (Column) On Update Cascade On Delete Cascade

Primary Key constraint

Alter Table Table add constraint [Primary Key] Primary key(Column1,Column2,.....)

.on() is for jQuery version 1.7 and above. If you have an older version, use this:

{
    // You can use array of words or a sentence split with space.
    var sentence = "The quick brown fox jumped over the lazy dog.";
    //var sentenceArray = ['asdf', 'asdf', 'sfd', 'qwr', 'qwr'];
    var sentenceArray = sentence.split(' ', 1000); 
    var output;
    var temp;
    for(var i = 0; i < sentenceArray.length; i++) {
        var k = 1;
        for(var j = i + 1; j < sentenceArray.length; j++) {
            if(sentenceArray[i] == sentenceArray[j])
                    k = k + 1;
        }
        if(k > 1) {
            i = i + 1;
            output = output + ',' + k + ',' + k;
        }
        else
            output = output + ',' + k;
    }
    alert(sentenceArray + '\n' + output.slice(10).split(',', 500));

* sudo rm -rf /usr/local/lib/dtrace/node.d

* brew link node (caused error with permissions)

* sudo chmod 777 /usr/local/lib/dtrace/node.d

You can write the command also for Bitbucket as mentioned by Dustin:

git push -f origin HEAD^:master

Note: instead of master you can use any branch. And it deletes just push on Bitbucket.

To remove last commit locally in git use:

git reset --hard HEAD~1

TL;DR

if [[ $(ls -A | head -c1 | wc -c) -ne 0 ]]; then ...; fi

Thanks to netj for a suggestion to improve my original:
if [[ $(ls -A | wc -c) -ne 0 ]]; then ...; fi

This is an old question but I see at least two things that need some improvement or at least some clarification.

First problem

First problem I see is that most of the examples provided here simply don't work. They use the ls -al and ls -Al commands - both of which output non-empty strings in empty directories. Those examples always report that there are files even when there are none.

For that reason you should use just ls -A - Why would anyone want to use the -l switch which means "use a long listing format" when all you want is test if there is any output or not, anyway?

So most of the answers here are simply incorrect.

Second problem

The second problem is that while some answers work fine (those that don't use ls -al or ls -Al but ls -A instead) they all do something like this:

1. run a command
2. buffer its entire output in RAM
3. convert the output into a huge single-line string
4. compare that string to an empty string

What I would suggest doing instead would be:

1. run a command
2. count the characters in its output without storing them
   • or even better - count the number of maximally 1 character using head -c1
     (thanks to netj for posting this idea in the comments below)
3. compare that number with zero

So for example, instead of:

if [[ $(ls -A) ]]

I would use:

if [[ $(ls -A | wc -c) -ne 0 ]]
# or:
if [[ $(ls -A | head -c1 | wc -c) -ne 0 ]]

Instead of:

if [ -z "$(ls -lA)" ]

I would use:

if [ $(ls -lA | wc -c) -eq 0 ]
# or:
if [ $(ls -lA | head -c1 | wc -c) -eq 0 ]

and so on.

For small outputs it may not be a problem but for larger outputs the difference may be significant:

$ time [ -z "$(seq 1 10000000)" ]

real    0m2.703s
user    0m2.485s
sys 0m0.347s

Compare it with:

$ time [ $(seq 1 10000000 | wc -c) -eq 0 ]

real    0m0.128s
user    0m0.081s
sys 0m0.105s

And even better:

$ time [ $(seq 1 10000000 | head -c1 | wc -c) -eq 0 ]

real    0m0.004s
user    0m0.000s
sys 0m0.007s

Full example

Updated example from the answer by Will Vousden:

if [[ $(ls -A | wc -c) -ne 0 ]]; then
    echo "there are files"
else
    echo "no files found"
fi

Updated again after suggestions by netj:

if [[ $(ls -A | head -c1 | wc -c) -ne 0 ]]; then
    echo "there are files"
else
    echo "no files found"
fi

Additional update by jakeonfire:

grep will exit with a failure if there is no match. We can take advantage of this to simplify the syntax slightly:

if ls -A | head -c1 | grep -E '.'; then
    echo "there are files"
fi

if ! ls -A | head -c1 | grep -E '.'; then
    echo "no files found"
fi

Discarding whitespace

If the command that you're testing could output some whitespace that you want to treat as an empty string, then instead of:

| wc -c

you could use:

| tr -d ' \n\r\t ' | wc -c

or with head -c1:

| tr -d ' \n\r\t ' | head -c1 | wc -c

or something like that.

Summary

1. First, use a command that works.

2. Second, avoid unnecessary storing in RAM and processing of potentially huge data.

The answer didn't specify that the output is always small so a possibility of large output needs to be considered as well.

give it float: right and the h1 float:left and put an element with clear:both after them.

One basic way that comes to mind would be to put the item into a table and have two cells, one with the text, the other with the image, and use style="valign:center" with the tags.

Try a conditional group matching 50-99 or any string of three or more digits:

var r = /^(?:[5-9]\d|\d{3,})$/

There's a simple way to do this if you only need to support modern browsers: on your submit button, add a formaction="/alternate/submit/url" attribute like so:

<form>
    [fields]
    <input type="submit" value="Submit to a" formaction="/submit/a">
    <input type="submit" value="submit to b" formaction="/submit/b">
</form>

It also works on <button> tags.

The gotcha is that old versions of IE (<10) and the Android Browser (<4.0) do not support it. So, if you need to support older browsers, then the existing JS answers will probably work better for you.

**It is Simple, just follow 2 steps. Step #1. Fire query "Delete from tableName", It will delete all records from table.

Step #2. There is table named "sqlite_sequence" in Sqlite Database, just browse it and you can set sequence table wise to "0" so it will start from auto id "1".** See the screenshot attached.

Best way to implement the selector is by using the xml instead of using programatic way as its more easy to implemnt with xml.

    <?xml version="1.0" encoding="utf-8"?>    
<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/button_bg_selected" android:state_selected="true"></item>
        <item android:drawable="@drawable/button_bg_pressed" android:state_pressed="true"></item>
        <item android:drawable="@drawable/button_bg_normal"></item>

    </selector>

Try running the command brew doctor and let us know what sort of output you get

edit: And to answer the title question, this is from their FAQ :

Homebrew doesn’t write files outside its prefix. So generally you can just rm -rf the folder you installed it in.

So following that up with a clean re-install (following their latest recommended steps) should be your best bet.

You should do something like this:

1) create directory object what would point to server-side accessible folder

CREATE DIRECTORY image_files AS '/data/images'
/

2) Place your file into OS folder directory object points to

3) Give required access privileges to Oracle schema what will load data from file into table:

GRANT READ ON DIRECTORY image_files TO scott
/

4) Use BFILENAME, EMPTY_BLOB functions and DBMS_LOB package (example NOT tested - be care) like in below:

DECLARE
  l_blob BLOB; 
  v_src_loc  BFILE := BFILENAME('IMAGE_FILES', 'myimage.png');
  v_amount   INTEGER;
BEGIN
  INSERT INTO esignatures  
  VALUES (100, 'BOB', empty_blob()) RETURN iblob INTO l_blob; 
  DBMS_LOB.OPEN(v_src_loc, DBMS_LOB.LOB_READONLY);
  v_amount := DBMS_LOB.GETLENGTH(v_src_loc);
  DBMS_LOB.LOADFROMFILE(l_blob, v_src_loc, v_amount);
  DBMS_LOB.CLOSE(v_src_loc);
  COMMIT;
END;
/

After this you get the content of your file in BLOB column and can get it back using Java for example.

edit: One letter left missing: it should be LOADFROMFILE.

Strings are immutable, so actully you can't change the String afterwards (you can only make the variable that held the String object point to a different String object).

However, that is not the reason why you can bind any variable to a final parameter. All the compiler checks is that the parameter is not reassigned within the method. This is good for documentation purposes, arguably good style, and may even help optimize the byte code for speed (although this seems not to do very much in practice).

But even if you do reassign a parameter within a method, the caller doesn't notice that, because java does all parameter passing by value. After the sequence

  a = someObject();
  process(a);

the fields of a may have changed, but a is still the same object it was before. In pass-by-reference languages this may not be true.

see docs: http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.insert.html

using loc = 0 will insert at the beginning

df.insert(loc, column, value)

df = pd.DataFrame({'B': [1, 2, 3], 'C': [4, 5, 6]})

df
Out: 
   B  C
0  1  4
1  2  5
2  3  6

idx = 0
new_col = [7, 8, 9]  # can be a list, a Series, an array or a scalar   
df.insert(loc=idx, column='A', value=new_col)

df
Out: 
   A  B  C
0  7  1  4
1  8  2  5
2  9  3  6

This would work

setInterval(function(){$("#myButtonId").click();}, 1000);

JSTool is the best for stability.

1. Select menu Plugins>Plugin Manager>Show Plugin Manager
2. Check to JSTool checkbox > Install > Restart Notepad++
3. Open js file > Plugins > JSTool > JSFormat

Dependency Management allows to consolidate and centralize the management of dependency versions without adding dependencies which are inherited by all children. This is especially useful when you have a set of projects (i.e. more than one) that inherits a common parent.

Another extremely important use case of dependencyManagement is the control of versions of artifacts used in transitive dependencies. This is hard to explain without an example. Luckily, this is illustrated in the documentation.

Now there is official FAQ for using Google Play in How do I install Google Play Services?, here the FAQ text:

For intellectual property reasons, Google Play Services are not included by default in Genymotion virtual devices. However, if you really need them, you can use the packages provided by OpenGapps. Simply follow these steps:

1. Visit opengapps.org
2. Select x86 as platform
3. Choose the Android version corresponding to your virtual device
4. Select nano as variant
5. Download the zip file
6. Drag & Drop the zip installer in new Genymotion virtual device (2.7.2 and above only)
7. Follow the pop-up instructions

Please note Genymobile Inc. and Genymotion assume no liability whatsoever resulting from the download, install and use of Google Play Services within your virtual devices. You are solely responsible for the use and assume all liability related thereto. Moreover, we disclaim any warranties of any kind for a particular purpose regarding the compatibility of the OpenGapps packages with any version of Genymotion.

Open eclipse go to Servers panel, right click or press F3 to open Overview window and go to Ports (Modify the server ports). You will get the following:

curl -s http://google.com > temp.html

works for curl version 7.19.5 on Ubuntu 9.10 (no progress bar). But if for some reason that does not work on your platform, you could always redirect stderr to /dev/null:

curl  http://google.com 2>/dev/null > temp.html

Generally you should also override hashCode() each time you override equals(), even if just for the performance boost. HashCode() decides which 'bucket' your object gets sorted into when doing a comparison, so any two objects which equal() evaluates to true should return the same hashCode value(). I cannot remember the default behavior of hashCode() (if it returns 0 then your code should work but slowly, but if it returns the address then your code will fail). I do remember a bunch of times when my code failed because I forgot to override hashCode() though. :)

Not fitting 100% to this particular question but if you want to split from the back you can do it like this:

theStringInQuestion[::-1].split('/', 1)[1][::-1]

This code splits once at symbol '/' from behind.

#!/bin/bash

read -p "Enter a directory: " BASEPATH

SUBFOLD1=${BASEPATH%%/}/subFold1
SUBFOLD2=${BASEPATH%%/}/subFold2

echo "I will create $SUBFOLD1 and $SUBFOLD2"

# mkdir -p $SUBFOLD1
# mkdir -p $SUBFOLD2

And if you want to use readline so you get completion and all that, add a -e to the call to read:

read -e -p "Enter a directory: " BASEPATH

This code works for me:

public void Run()
{
    Dog myDog = new Dog();
    myDog.Name= "Foo";
    myDog.Color = DogColor.Brown;

    System.Console.WriteLine("{0}", myDog.ToString());

    MemoryStream stream = SerializeToStream(myDog);

    Dog newDog = (Dog)DeserializeFromStream(stream);

    System.Console.WriteLine("{0}", newDog.ToString());
}

Where the types are like this:

[Serializable]
public enum DogColor
{
    Brown,
    Black,
    Mottled
}

[Serializable]
public class Dog
{
    public String Name
    {
        get; set;
    }

    public DogColor Color
    {
        get;set;
    }

    public override String ToString()
    {
        return String.Format("Dog: {0}/{1}", Name, Color);
    }
}

and the utility methods are:

public static MemoryStream SerializeToStream(object o)
{
    MemoryStream stream = new MemoryStream();
    IFormatter formatter = new BinaryFormatter();
    formatter.Serialize(stream, o);
    return stream;
}

public static object DeserializeFromStream(MemoryStream stream)
{
    IFormatter formatter = new BinaryFormatter();
    stream.Seek(0, SeekOrigin.Begin);
    object o = formatter.Deserialize(stream);
    return o;
}

This should work:

ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")

You can set CustomFormat property to "dd-MM-yyyy" in design mode and use dateTimePicker1.Text property to fetch string in "dd/MM/yyyy" format irrespective of display format.

You could prototype your own splice() into String.

Polyfill

if (!String.prototype.splice) {
    /**
     * {JSDoc}
     *
     * The splice() method changes the content of a string by removing a range of
     * characters and/or adding new characters.
     *
     * @this {String}
     * @param {number} start Index at which to start changing the string.
     * @param {number} delCount An integer indicating the number of old chars to remove.
     * @param {string} newSubStr The String that is spliced in.
     * @return {string} A new string with the spliced substring.
     */
    String.prototype.splice = function(start, delCount, newSubStr) {
        return this.slice(0, start) + newSubStr + this.slice(start + Math.abs(delCount));
    };
}

Example

String.prototype.splice = function(idx, rem, str) {_x000D_
    return this.slice(0, idx) + str + this.slice(idx + Math.abs(rem));_x000D_
};_x000D_
_x000D_
var result = "foo baz".splice(4, 0, "bar ");_x000D_
_x000D_
document.body.innerHTML = result; // "foo bar baz"

EDIT: Modified it to ensure that rem is an absolute value.

This eventually helped me:

    var x = 0;
    var buttonText = 'LOADING';

    $('#startbutton').click(function(){
        $(this).text(buttonText);
        window.setTimeout(addDotToButton,2000);
    })

    function addDotToButton(){
        x++;
        buttonText += '.';
        $('#startbutton').text(buttonText);

        if (x < 4) window.setTimeout(addDotToButton, 2000);
        else location.reload(true);
    }

Put 0 as default in SQL or add 0 into your area of table

Just a delegate that returns a boolean. It is used a lot in filtering lists but can be used wherever you'd like.

List<DateRangeClass>  myList = new List<DateRangeClass<GetSomeDateRangeArrayToPopulate);
myList.FindAll(x => (x.StartTime <= minDateToReturn && x.EndTime >= maxDateToReturn):

var checkJSON = function(m) {

   if (typeof m == 'object') { 
      try{ m = JSON.stringify(m); }
      catch(err) { return false; } }

   if (typeof m == 'string') {
      try{ m = JSON.parse(m); }
      catch (err) { return false; } }

   if (typeof m != 'object') { return false; }
   return true;

};


checkJSON(JSON.parse('{}'));      //true
checkJSON(JSON.parse('{"a":0}')); //true
checkJSON('{}');                  //true
checkJSON('{"a":0}');             //true
checkJSON('x');                   //false
checkJSON('');                    //false
checkJSON();                      //false

You may also need to provide your contact info, bank info, and tax info in this page so it will allow your last release on App Store:

https://itunesconnect.apple.com/WebObjects/iTunesConnect.woa/wo/6.0

You can check if an object is nil (null) by calling present? or blank? .

@object.present?

this will return false if the project is an empty string or nil .

or you can use

@object.blank?

this is the same as present? with a bang and you can use it if you don't like 'unless'. this will return true for an empty string or nil .

I had a similar issue, but in my case, it was my CSS file.

I had loaded my CSS file before the JQuery library, since my jquery function was interaction with my css file, my jquery function wasn't working. I found this weird, but when I loaded the CSS file after loading the JQuery library, it worked.

This might not be directly related to the Question, but it may help others who might be facing a similar problem.

My issue:

    <link rel="stylesheet" href="style.css">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
    <script type="text/javascript" src="slider.js"></script>

My solution:

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

Same as suggested by PherricOxide but in C

#include <sys/stat.h>
int exist(const char *name)
{
  struct stat   buffer;
  return (stat (name, &buffer) == 0);
}

It's not what the OP asked for (capturing groups) but you can extract the numbers using:

S='This is a sample 123 text and some 987 numbers'
echo "$S" | sed 's/ /\n/g' | sed -r '/([0-9]+)/ !d'

Gives the following:

123
987

This partly depends on what you want to happen if you run into duplicates. For instance, you could do:

var result = dictionaries.SelectMany(dict => dict)
                         .ToDictionary(pair => pair.Key, pair => pair.Value);

That will throw an exception if you get any duplicate keys.

EDIT: If you use ToLookup then you'll get a lookup which can have multiple values per key. You could then convert that to a dictionary:

var result = dictionaries.SelectMany(dict => dict)
                         .ToLookup(pair => pair.Key, pair => pair.Value)
                         .ToDictionary(group => group.Key, group => group.First());

It's a bit ugly - and inefficient - but it's the quickest way to do it in terms of code. (I haven't tested it, admittedly.)

You could write your own ToDictionary2 extension method of course (with a better name, but I don't have time to think of one now) - it's not terribly hard to do, just overwriting (or ignoring) duplicate keys. The important bit (to my mind) is using SelectMany, and realising that a dictionary supports iteration over its key/value pairs.

Great tutorial, fantastic presentation. Neat, simple, short and very explanatory. Although, notification.setLatestEventInfo(this, getText(R.string.service_label), text, contentIntent); method is no more. As trante stated here, good approach would be:

private static final int NOTIFICATION_ID = 45349;

private void showNotification() {
    NotificationCompat.Builder builder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("My Notification Title")
                    .setContentText("Something interesting happened");

    Intent targetIntent = new Intent(this, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, targetIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);
    _nManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    _nManager.notify(NOTIFICATION_ID, builder.build());
}

@Override
public void onDestroy() {
    super.onDestroy();
    if (_timer != null) {_timer.cancel();}
    _counter=0;
    _nManager.cancel(NOTIFICATION_ID); // Cancel the persistent notification.
    Log.i("PlaybackService", "Service Stopped.");
    _isRunning = false;
}

Checked myself, everything works like a charm (activity and service names may differ from original).

<% form_for(@message) do |f| %>
  <%= f.radio_button :contactmethod, 'email', :checked => true %> 
  <%= label :contactmethod_email, 'Email' %>
  <%= f.radio_button :contactmethod, 'sms' %>
  <%= label :contactmethod_sms, 'SMS' %>
<% end %>

below code is working for both with header and without header to print log request & response. Note: Just comment .addHeader() line if are not using header.

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(interceptor)
                //.addInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR)
                .addNetworkInterceptor(new Interceptor() {

                    @Override

                    public okhttp3.Response intercept(Chain chain) throws IOException {
                        Request request = chain.request().newBuilder()
                                // .addHeader(Constant.Header, authToken)
                                   .build();
                        return chain.proceed(request);
                    }
                }).build();

        final Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Constant.baseUrl)
                .client(client) // This line is important
                .addConverterFactory(GsonConverterFactory.create())
                .build();

I'm using this function

function isNull() {
    for (var i = 0; i < arguments.length; i++) {
        if (
            typeof arguments[i] !== 'undefined'
            && arguments[i] !== undefined
            && arguments[i] != null
            && arguments[i] != NaN
            && arguments[i] 
        ) return arguments[i];
      }
}

test

console.log(isNull(null, null, undefined, 'Target'));

If you are using ThreeTen Backport including ThreeTenABP

    Date input = new Date(); // Imagine your Date here
    LocalDate date = DateTimeUtils.toInstant(input)
            .atZone(ZoneId.systemDefault())
            .toLocalDate();

If you are using the backport of JSR 310, either you haven’t got a Date.toInstant() method or it won’t give you the org.threeten.bp.Instant that you need for you further conversion. Instead you need to use the DateTimeUtils class that comes as part of the backport. The remainder of the conversion is the same, so so is the explanation.

VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the results of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation.

On Error Resume Next

DoStep1

If Err.Number <> 0 Then
  WScript.Echo "Error in DoStep1: " & Err.Description
  Err.Clear
End If

DoStep2

If Err.Number <> 0 Then
  WScript.Echo "Error in DoStop2:" & Err.Description
  Err.Clear
End If

'If you no longer want to continue following an error after that block's completed,
'call this.
On Error Goto 0

The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above.

There are performance consequences to deep-diving an object in your $watch. Sometimes (for example, when changes are only pushes and pops), you might want to $watch an easily calculated value, such as array.length.

GenSON (PyPI | Github) is a JSON Schema generator that can generate a single schema from multiple objects. You can also merge schemas with it. It is written in Python and comes with a CLI tool.

(Full disclosure: I'm the author.)

You should download the chromeDriver in a folder, and add this folder in your PATH environment variable.

You'll have to restart your console to make it work.

I'm a java developer that happened to get on a team without a DBA and one where as a developer, I can't get DBA rights. I was tasked with moving an entire schema between two databases, so without having a DBA, I had to do it and do it by running scripts, not being able to use the GUI in SQL Server 2008 because I didn't have admin privileges.

Everything was moved without issue, however, when running a stored procedure on the new schema.table, I found I lost the identity field in a table. I double checked the script that created the table and it was there, however, SQL Server didn't get it when I ran the script. I was told later by a DBA that he had seen this same problem before.

In any event, for SQL Server 2008, these are the steps I took to get this resolved and they worked, so I'm posting this here in the hopes it will be a help to someone. This is what I did as I had FK dependencies on another table that made this more difficult:

I used this query to verify the identity was indeed missing and to view dependencies on the table.

1.) Find statistics on a table:

exec sp_help 'dbo.table_name_old';

2.) Create a duplicate, identical new table, except add an identity field on the PK field where it had been before.

3.) Disable the identity to move data.

SET IDENTITY_INSERT dbo.table_name ON 

4.) Transfer the data.

INSERT INTO dbo.table_name_new
(
field1, field2, etc...
)
SELECT 
field1, field2, etc...
FROM 
dbo.table_name_old;

5.) Verify the data is there.

SELECT * FROM dbo.table_name_new

6.) Re-enable the identity.

SET IDENTITY_INSERT ToyRecP.ToyAwards.lkpFile_New OFF

7.) This is the best script I found to get all the FK relationships to verify which table(s) the original table references as dependencies and I came across many, so it is a keeper!

SELECT f.name AS ForeignKey,
   OBJECT_NAME(f.parent_object_id) AS TableName,
   COL_NAME(fc.parent_object_id, fc.parent_column_id) AS ColumnName,
   OBJECT_NAME (f.referenced_object_id) AS ReferenceTableName,
   COL_NAME(fc.referenced_object_id, fc.referenced_column_id) AS ReferenceColumnName
FROM sys.foreign_keys AS f
INNER JOIN sys.foreign_key_columns AS fc
   ON f.OBJECT_ID = fc.constraint_object_id
   ORDER BY ReferenceTableName;

8.) Make sure you have all the PK and FK scripts for all the tables involved, before this next step.

9.) You can right-click on each key and script this using SQL Server 2008

10.) Drop the FK(s) from the dependency table(s) using this syntax:

ALTER TABLE [dbo].[table_name] DROP CONSTRAINT [Name_of_FK]

11.) Drop the original table:

DROP TABLE dbo.table_name_old;

13.) These next steps rely on the scripts you created in SQL Server 2008 in step 9.

--Add the PK to the new table.

--Add the FK to the new table.

--Add the FK's back to the dependency table.

14.) Verify everything is correct and complete. I used the GUI to look at the tables.

15.) Rename the new table to the original tables name.

exec sp_RENAME '[Schema_Name.OldTableName]' , '[NewTableName]';

Finally, everything worked!

Start by get the content from file and trim the white spaces if any found in each line of the text document. That becomes the object passed to the where-object to go through the array looking at each member of the array with string length greater then 0. That object is passed to replace the content of the file you started with. It would probably be better to make a new file... Last thing to do is reads back the newly made file's content and see your awesomeness.

(Get-Content ./copy.txt).Trim() | Where-Object{$_.length -gt 0} | Set-Content ./copy.txt

G'day, I too can say that I tried everything mentioned in these posts and a few more from elsewhere. The #1 problem for me was that the new Intent always had a null bundle. My issue was in focusing too much on the details of "have I included .this or .that". My solution was in taking a step back from the detail and looking at the overall structure of the notification. When I did that I managed to place the key parts of the code in the correct sequence. So, if you're having similar issues check for:

1. Intent notificationIntent = new Intent(MainActivity.this, NotificationActivity.class);

2a. Bundle bundle = new Bundle();

//I like specifying the data type much better. eg bundle.putInt

2b. notificationIntent.putExtras(bundle);
3. PendingIntent contentIntent = PendingIntent.getActivity(MainActivity.this, WIZARD_NOTIFICATION_ID, notificationIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
4. NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
5.          NotificationCompat.Builder nBuilder =
                    new NotificationCompat.Builder(this)
                            .setSmallIcon(R.drawable.ic_notify)
                            .setContentTitle(title)
                            .setContentText(content)
                            .setContentIntent(contentIntent)
                            .setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE)
                            .setAutoCancel(false)//false is standard. true == automatically removes the notification when the user taps it.
                            .setColor(getResources().getColor(R.color.colorPrimary))
                            .setCategory(Notification.CATEGORY_REMINDER)
                            .setPriority(Notification.PRIORITY_HIGH)
                            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC);
            notificationManager.notify(WIZARD_NOTIFICATION_ID, nBuilder.build());

With this sequence I get a valid bundle.

For anyone else who lands here I'd like to add on to Günter Zöchbauer's answer this was my solution for implementing a utility to know if there's internet or not regardless of anything else.

Disclaimer:

I'm new to both Dart and Flutter so this may not be the best approach, but would love to get feedback.

Combining flutter_connectivity and Günter Zöchbauer's connection test

My requirements

I didn't want to have a bunch of repeated code anywhere I needed to check the connection and I wanted it to automatically update components or anything else that cared about the connection whenever there was a change.

ConnectionStatusSingleton

First we setup a Singleton. If you're unfamiliar with this pattern there's a lot of good info online about them. But the gist is that you want to make a single instance of a class during the application life cycle and be able to use it anywhere.

This singleton hooks into flutter_connectivity and listens for connectivity changes, then tests the network connection, then uses a StreamController to update anything that cares.

It looks like this:

import 'dart:io'; //InternetAddress utility
import 'dart:async'; //For StreamController/Stream

import 'package:connectivity/connectivity.dart';

class ConnectionStatusSingleton {
    //This creates the single instance by calling the `_internal` constructor specified below
    static final ConnectionStatusSingleton _singleton = new ConnectionStatusSingleton._internal();
    ConnectionStatusSingleton._internal();

    //This is what's used to retrieve the instance through the app
    static ConnectionStatusSingleton getInstance() => _singleton;

    //This tracks the current connection status
    bool hasConnection = false;

    //This is how we'll allow subscribing to connection changes
    StreamController connectionChangeController = new StreamController.broadcast();

    //flutter_connectivity
    final Connectivity _connectivity = Connectivity();

    //Hook into flutter_connectivity's Stream to listen for changes
    //And check the connection status out of the gate
    void initialize() {
        _connectivity.onConnectivityChanged.listen(_connectionChange);
        checkConnection();
    }

    Stream get connectionChange => connectionChangeController.stream;

    //A clean up method to close our StreamController
    //   Because this is meant to exist through the entire application life cycle this isn't
    //   really an issue
    void dispose() {
        connectionChangeController.close();
    }

    //flutter_connectivity's listener
    void _connectionChange(ConnectivityResult result) {
        checkConnection();
    }

    //The test to actually see if there is a connection
    Future<bool> checkConnection() async {
        bool previousConnection = hasConnection;

        try {
            final result = await InternetAddress.lookup('google.com');
            if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
                hasConnection = true;
            } else {
                hasConnection = false;
            }
        } on SocketException catch(_) {
            hasConnection = false;
        }

        //The connection status changed send out an update to all listeners
        if (previousConnection != hasConnection) {
            connectionChangeController.add(hasConnection);
        }

        return hasConnection;
    }
}

Usage

Initialization

First we have to make sure we call the initialize of our singleton. But only once. This parts up to you but I did it in my app's main():

void main() {
    ConnectionStatusSingleton connectionStatus = ConnectionStatusSingleton.getInstance();
    connectionStatus.initialize();

    runApp(MyApp());

    //Call this if initialization is occuring in a scope that will end during app lifecycle
    //connectionStatus.dispose();   
}

In Widget or elsewhere

import 'dart:async'; //For StreamSubscription

...

class MyWidgetState extends State<MyWidget> {
    StreamSubscription _connectionChangeStream;

    bool isOffline = false;

    @override
    initState() {
        super.initState();

        ConnectionStatusSingleton connectionStatus = ConnectionStatusSingleton.getInstance();
        _connectionChangeStream = connectionStatus.connectionChange.listen(connectionChanged);
    }

    void connectionChanged(dynamic hasConnection) {
        setState(() {
            isOffline = !hasConnection;
        });
    }

    @override
    Widget build(BuildContext ctxt) {
        ...
    }
}

Hope somebody else finds this useful!

You need to use Arrow function ()=> ES6 feature to preserve this context within setTimeout.

// var that = this;                             // no need of this line
this.messageSuccess = true;

setTimeout(()=>{                           //<<<---using ()=> syntax
      this.messageSuccess = false;
 }, 3000);

You can also do this

<input type="hidden" name="text" value="{% url 'dashboard' %}" />

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

1. Removing whitespace from the entire file being edited:

Preferences -> Java -> Editors -> Save Actions -> check Perform the selected actions on save -> check Additional actions -> click Configure.. -> go to Code organizing tab -> check Remove trailing whitespace -> select All lines.

2. Removing whitespace only from the lines I changed:

Preferences -> Java -> Editor -> Save Actions -> check "Perform the selected actions on save -> check Format source code -> select Format edited lines.

Note it is not necessary to click Configure the formatter settings on the Formatter page - all the code styles automatically include removing trailing whitespace. At least I couldn't find a setting for this in Formatter configuration, and it worked out of the box for built-in Java Conventions, Eclipse, Eclipse 2.1 styles, as well as GoogleStyle.

When using this set-up, you obviously need to also turn off the solution to part 1 of the question.

Eclipse version checked: 4.5.2, 4.11

This worked for me with some css frameworks (material design lite [MDL]).

Based on @engineforce answer, I made this class that I'm using in a PCL project of a Xamarin Solution:

/// <summary>
/// Based on: https://stackoverflow.com/a/42264037/6155481
/// </summary>
public class ObjectDumper
{
    public static string Dump(object obj)
    {
        return new ObjectDumper().DumpObject(obj);
    }

    StringBuilder _dumpBuilder = new StringBuilder();

    string DumpObject(object obj)
    {
        DumpObject(obj, 0);

        conn.setRequestMethod("POST");

        conn.setRequestProperty("Content-Type", "application/json; charset=utf-8");

        if (msCookieManager.getCookieStore().getCookies().size() > 0) {
            //While joining the Cookies, use ',' or ';' as needed. Most of the server are using ';'
            conn.setRequestProperty(COOKIE ,
                    TextUtils.join(";", msCookieManager.getCookieStore().getCookies()));

Execute the following on your terminal to get the latest stable version:

sudo gem install cocoapods

Add --pre to get the latest pre release:

sudo gem install cocoapods --pre

If you originally installed the cocoapods gem using sudo, you should use that command again.

Later on, when you're actively using CocoaPods by installing pods, you will be notified when new versions become available with a CocoaPods X.X.X is now available, please update message.

DFS(analysis):

• Setting/getting a vertex/edge label takes O(1) time
• Each vertex is labeled twice
  • once as UNEXPLORED
  • once as VISITED
• Each edge is labeled twice
  • once as UNEXPLORED
  • once as DISCOVERY or BACK
• Method incidentEdges is called once for each vertex
• DFS runs in O(n + m) time provided the graph is represented by the adjacency list structure
• Recall that Sv deg(v) = 2m

BFS(analysis):

• Setting/getting a vertex/edge label takes O(1) time
• Each vertex is labeled twice

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

There are a couple of ways:

To delete it directly:

SomeModel.objects.filter(id=id).delete()

To delete it from an instance:

instance1 = SomeModel.objects.get(id=id)
instance1.delete()

// don't use same name
