Yah Im pretty sure you just put

    break;

right where you want it to exit

like

    if (variable == 1)
    {
    //do something
    }
    else
    {
    //exit
    break;
    }

Use .apply() to have the same access to arguments in function b, like this:

function a(){
    b.apply(null, arguments);
}
function b(){
   alert(arguments); //arguments[0] = 1, etc
}
a(1,2,3);?

You can test it out here.

Just add one to the result. That turns [0, 10) into (0,10] (for integers). [0, 10) is just a more confusing way to say [0, 9], and (0,10] is [1,10] (for integers).

Here's a helpful article on long polling (long-held HTTP request) using jQuery. A code snippet derived from this article:

(function poll() {
    setTimeout(function() {
        $.ajax({
            url: "/server/api/function",
            type: "GET",
            success: function(data) {
                console.log("polling");
            },
            dataType: "json",
            complete: poll,
            timeout: 2000
        })
    }, 5000);
})();

This will make the next request only after the ajax request has completed.

A variation on the above that will execute immediately the first time it is called before honouring the wait/timeout interval.

(function poll() {
    $.ajax({
        url: "/server/api/function",
        type: "GET",
        success: function(data) {
            console.log("polling");
        },
        dataType: "json",
        complete: setTimeout(function() {poll()}, 5000),
        timeout: 2000
    })
})();

Like taro said, keys returns the array of keys of your Hash:

http://ruby-doc.org/core-1.9.3/Hash.html#method-i-keys

You'll find all the different methods available for each class.

If you don't know what you're dealing with:

 puts my_unknown_variable.class.to_s

This will output the class name.

Don't use in-line JavaScript, separate your behaviour from your data and it gets much easier to handle. I'd suggest the following:

var table = document.getElementById('tableID'),
    cells = table.getElementsByTagName('td');

for (var i=0,len=cells.length; i<len; i++){
    cells[i].onclick = function(){
        console.log(this.innerHTML);
        /* if you know it's going to be numeric:
        console.log(parseInt(this.innerHTML),10);
        */
    }
}

var table = document.getElementById('tableID'),_x000D_
  cells = table.getElementsByTagName('td');_x000D_
_x000D_
for (var i = 0, len = cells.length; i < len; i++) {_x000D_

A revised approach, in response to the comment (below):

You're missing a semicolon. Also, don't make functions within a loop.

This revision binds a (single) named function as the click event-handler of the multiple <td> elements, and avoids the unnecessary overhead of creating multiple anonymous functions within a loop (which is poor practice due to repetition and the impact on performance, due to memory usage):

function logText() {
  // 'this' is automatically passed to the named
  // function via the use of addEventListener()
  // (later):
  console.log(this.textContent);
}

// using a CSS Selector, with document.querySelectorAll()
// to get a NodeList of <td> elements within the #tableID element:
var cells = document.querySelectorAll('#tableID td');

// iterating over the array-like NodeList, using
// Array.prototype.forEach() and Function.prototype.call():
Array.prototype.forEach.call(cells, function(td) {
  // the first argument of the anonymous function (here: 'td')
  // is the element of the array over which we're iterating.

  // adding an event-handler (the function logText) to handle
  // the click events on the <td> elements:
  td.addEventListener('click', logText);
});

function logText() {_x000D_
  console.log(this.textContent);_x000D_
}_x000D_

There are a lot of awkward and unnecessarily complicated answers on this page. The highest rated one, @amateur's, is quite good, although it has a bit of unnecessary fluff in the RegExp. Here is a slightly more optimal solution with cleaner RegExp and a cleaner replace call:

function updateQueryStringParamsNoHash(uri, key, value) {
  var re = new RegExp("([?&])" + key + "=[^&]*", "i");
  return re.test(uri)
       ? uri.replace(re, '$1' + key + "=" + value)
       : uri + separator + key + "=" + value
  ;
}

As an added bonus, if uri is not a string, you won't get errors for trying to call match or replace on something that may not implement those methods.

And if you want to handle the case of a hash (and you've already done a check for properly formatted HTML), you can leverage the existing function instead of writing a new function containing the same logic:

function updateQueryStringParams(url, key, value) {
    var splitURL = url.split('#');
    var hash = splitURL[1];
    var uri = updateQueryStringParamsNoHash(splitURL[0]);
    return hash == null ? uri : uri + '#' + hash;
}

Or you can make some slight changes to @Adam's otherwise excellent answer:

function updateQueryStringParameter(uri, key, value) {
  var re = new RegExp("([?&])" + key + "=[^&#]*", "i");
  if (re.test(uri)) {
    return uri.replace(re, '$1' + key + "=" + value);
  } else {
    var matchData = uri.match(/^([^#]*)(#.*)?$/);
    var separator = /\?/.test(uri) ? "&" : "?";    
    return matchData[0] + separator + key + "=" + value + (matchData[1] || '');
  }
}

There is a massive difference in the example you have posted, the first version:

var urls = await context.Urls.ToListAsync();

This is bad, it basically does select * from table, returns all results into memory and then applies the where against that in memory collection rather than doing select * from table where... against the database.

The second method will not actually hit the database until a query is applied to the IQueryable (probably via a linq .Where().Select() style operation which will only return the db values which match the query.

If your examples were comparable, the async version will usually be slightly slower per request as there is more overhead in the state machine which the compiler generates to allow the async functionality.

However the major difference (and benefit) is that the async version allows more concurrent requests as it doesn't block the processing thread whilst it is waiting for IO to complete (db query, file access, web request etc).

In kotlin don't use getters and setters as like in java.The correct format of the kotlin is given below.

val textView: TextView = findViewById(R.id.android_text) as TextView
textView.setOnClickListener {
    textView.text = getString(R.string.name)
}

To get the values from the Textview we have to use this method

 val str: String = textView.text.toString()

 println("the value is $str")

Try this

SELECT * FROM
    (
        SELECT T.*, ROW_NUMBER() OVER() R FROM TABLE T
    )
    WHERE R BETWEEN 10000 AND 20000

Here Response.Write():to display only string and you can not display any other data type values like int,date,etc.Conversion(from one data type to another) is not allowed. whereas Response .Output .Write(): you can display any type of data like int, date ,string etc.,by giving index values.

Here is example:

protected void Button1_Click(object sender, EventArgs e)
    {
       Response.Write ("hi good morning!"+"is it right?");//only strings are allowed        
       Response.Write("Scott is {0} at {1:d}", "cool", DateTime.Now);//this will give error(conversion is not allowed)
       Response.Output.Write("\nhi goood morning!");//works fine
       Response.Output.Write("Jai is {0} on {1:d}", "cool", DateTime.Now);//here the current date will be converted into string and displayed
    }

You may do it with JavaScript:

1. Get CSS styles of real button with getComputedStyle(realButton).
2. Apply the styles to all your links.

If column is not NOT NULL (nullable).

You just put NULL instead of value in INSERT statement.

background:rgba(0,0,0,0);
opacity:1;

This will do the trick

.gallery-item
{
  opacity:1;
}

.gallery-item:hover
{
  opacity:0;
  transition: opacity .2s ease-out;
  -moz-transition: opacity .2s ease-out;
  -webkit-transition: opacity .2s ease-out;
  -o-transition: opacity .2s ease-out;
}

This is of course subjective, but I think it strongly improves on two points:

• It is now immediately obvious that your function has nothing left to do if condition holds.
• It keeps the nesting level down. Nesting hurts readability more than you'd think.

You can make the border transparent. In this way it exists, but is invisible, so it doesn't push anything around:

.jobs .item {
   background: #eee;
   border: 1px solid transparent;
}

.jobs .item:hover {
   background: #e1e1e1;
   border: 1px solid #d0d0d0;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

For elements that already have a border, and you don't want them to move, you can use negative margins:

.jobs .item {
    background: #eee;
    border: 1px solid #d0d0d0;
}

.jobs .item:hover {
   background: #e1e1e1;
    border: 3px solid #d0d0d0;
    margin: -2px;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

Another possible trick for adding width to an existing border is to add a box-shadow with the spread attribute of the desired pixel width.

.jobs .item {
    background: #eee;
    border: 1px solid #d0d0d0;
}

.jobs .item:hover {
    background: #e1e1e1;
    box-shadow: 0 0 0 2px #d0d0d0;
}

<div class="jobs">
  <div class="item">Item</div>
</div>

An incomplete type error is when the compiler encounters the use of an identifier that it knows is a type, for instance because it has seen a forward-declaration of it (e.g. class stringstream;), but it hasn't seen a full definition for it (class stringstream { ... };).

This could happen for a type that you haven't used in your own code but is only present through included header files -- when you've included header files that use the type, but not the header file where the type is defined. It's unusual for a header to not itself include all the headers it needs, but not impossible.

For things from the standard library, such as the stringstream class, use the language standard or other reference documentation for the class or the individual functions (e.g. Unix man pages, MSDN library, etc.) to figure out what you need to #include to use it and what namespace to find it in if any. You may need to search for pages where the class name appears (e.g. man -k stringstream).

According to the docs, you can just do:

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from USER_INDEXES

or

select INDEX_NAME, TABLE_OWNER, TABLE_NAME, UNIQUENESS from ALL_INDEXES

if you want all indexes...

If you are using Sql Server Management Studio, you can create your own schema by browsing to Databases - Your Database - Security - Schemas.

To create one using a script is as easy as (for example):

CREATE SCHEMA [EnterSchemaNameHere] AUTHORIZATION [dbo]

You can use them to logically group your tables, for example by creating a schema for "Financial" information and another for "Personal" data. Your tables would then display as:

Financial.BankAccounts Financial.Transactions Personal.Address

Rather than using the default schema of dbo.

By Definition we can drag out the differences of two:

Factory: An interface is used for creating an object, but subclass decides which class to instantiate. The creation of object is done when it is required.

Abstract Factory: Abstract Factory pattern acts as a super-factory which creates other factories. In Abstract Factory pattern an interface is responsible for creating a set of related objects, or dependent objects without specifying their concrete classes.

So, in the definitions above we can emphasize on a particular difference. that is, Factory pattern is responsible for creating objects and Abstract Factory is responsible for creating a set of related objects; obviously both through an interface.

Factory pattern:

public interface IFactory{
  void VehicleType(string n);
 }

 public class Scooter : IFactory{
  public void VehicleType(string n){
   Console.WriteLine("Vehicle type: " + n);
  }
 }

 public class Bike : IFactory{
  public void VehicleType(string n) {
  Console.WriteLine("Vehicle type: " + n);
  }
 }

 public interface IVehicleFactory{
  IFactory GetVehicleType(string Vehicle);
 }

 public class ConcreteVehicleFactory : IVehicleFactory{
 public IFactory GetVehicleType(string Vehicle){
   switch (Vehicle){
    case "Scooter":
     return new Scooter();
    case "Bike":
     return new Bike();
    default:
    return new Scooter();
  }
 }

 class Program{
  static void Main(string[] args){
   IVehicleFactory factory = new ConcreteVehicleFactory();
   IFactory scooter = factory.GetVehicleType("Scooter");
   scooter.VehicleType("Scooter");

   IFactory bike = factory.GetVehicleType("Bike");
   bike.VehicleType("Bike");

   Console.ReadKey();
 }
}

Abstract Factory Pattern:

interface IVehicleFactory{
 IBike GetBike();
 IScooter GetScooter();
}

class HondaFactory : IVehicleFactory{
     public IBike GetBike(){
            return new FZS();
     }
     public IScooter GetScooter(){
            return new FZscooter();
     }
 }
class HeroFactory: IVehicleFactory{
      public IBike GetBike(){
            return new Pulsur();
     }
      public IScooter GetScooter(){
            return new PulsurScooter();
     }
}

interface IBike
    {
        string Name();
    }
interface IScooter
    {
        string Name();
    }

class FZS:IBike{
   public string Name(){
     return "FZS";
   }
}
class Pulsur:IBike{
   public string Name(){
     return "Pulsur";
   }
}

class FZscooter:IScooter {
  public string Name(){
     return "FZscooter";
   }
}

class PulsurScooter:IScooter{
  public string Name(){
     return "PulsurScooter";
   }
}

        public VehicleTypeCheck(MANUFACTURERS m){
            manu = m;
        }

        public void CheckProducts()
        {
            switch (manu){
                case MANUFACTURERS.HONDA:
                    factory = new HondaFactory();
                    break;
                case MANUFACTURERS.HERO:
                    factory = new HeroFactory();
                    break;
            }

      Console.WriteLine("Bike: " + factory.GetBike().Name() + "\nScooter: " +      factory.GetScooter().Name());
        }
  }

class Program
    {
        static void Main(string[] args)
        {
            VehicleTypeCheck chk = new VehicleTypeCheck(MANUFACTURERS.HONDA);
            chk.CheckProducts();

            chk= new VehicleTypeCheck(MANUFACTURERS.HERO);
            chk.CheckProducts();

            Console.Read();
        }
    }

Web Site = use when the website is created by graphic designers and the programmers only edit one or two pages

Web Application = use when the application is created by programmers and the graphic designers only edit one or two paged/images.

Web Sites can be worked on using any HTML tools without having to have developer studio, as project files don’t need to be updated, etc. Web applications are best when the team is mostly using developer studio and there is a high code content.

(Some coding errors are found in Web Applications at compile time that are not found in Web Sites until run time.)

Warning: I wrote this answer many years ago and have not used Asp.net since. I expect things have now moved on.

There are services available which allow you to artificially create origin timeouts by calling an API where you specify how long the server will take to respond. Server Timeout on macgyver is an example of such a service.

For example if you wanted to test a request that takes 15 seconds to respond you would simply make a post request to the macgyver API.

JSON Payload:

{
    "timeout_length": 15000
}

API Response (After 15 seconds):

{
    "response": "ok"
}

Server Timeout program on macgyver
https://askmacgyver.com/explore/program/server-timeout/3U4s6g6u

Runscope is a cloud based service that can monitor Web APIs using a set of tests. Tests can be , scheduled and/or run via parameterized web hooks. Tests can also be executed from data centers around the world to ensure response times are acceptable to global client base.

The free tier of Runscope supports up to 10K requests per month.

Disclaimer: I am a developer advocate for Runscope.

Yes, don't offset vertically or horizontally, and use a relatively large blur radius: fiddle

Also, you can use multiple box-shadows if you separate them with a comma. This will allow you to fine-tune where they blur and how much they extend. The example I provide is indistinguishable from a large outline, but it can be fine-tuned significantly more: fiddle

You missed the last and most relevant property of box-shadow, which is spread-distance. You can specify a value for how much the shadow expands or contracts (makes my second example obsolete): fiddle

The full property list is:

box-shadow: [horizontal-offset] [vertical-offset] [blur-radius] [spread-distance] [color] inset?

But even better, read through the spec.

            View view = inflater.inflate(R.layout.web_view, null);  // i have open a webview on the listview footer

Use Where-Object and test the $_.CreationTime:

Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") |

Most of the answers were good and right for your problem of

so i want to find the difference between date in number of days, how do i find difference in days?

I suggest this very simple and straightforward approach that is guaranteed to give you the correct difference in any time zone:

int difference= 
((int)((startDate.getTime()/(24*60*60*1000))
-(int)(endDate.getTime()/(24*60*60*1000))));

And that's it!

What I found to fix the issue regardless of kernel version, was taking the WGET options and having apt install them.

If NetBeans haven't created your dist folder, execute the do-dist ant target:

In commandline navigate to the directory of your project, the one containing a build.xml file
> ant do-dist

If ant runs fine (most likely), your dist folder will be created, containing the .war file.

Symfony doc to get request data

Finally, the raw data sent with the request body can be accessed using getContent():

$content = $request->getContent();

Personally, I'd go for the function approach

def get_parent_dir(directory):
    import os
    return os.path.dirname(directory)

current_dirs_parent = get_parent_dir(os.getcwd())

Please double check that jenkins is not blocking this import. Go to script approvals and check to see if it is blocking it. If it is click allow.

You create the relationships the other way around; add foreign keys to the Person type to create a Many-to-One relationship:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        Anniversary, on_delete=models.CASCADE)
    address = models.ForeignKey(
        Address, on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person entries.

Anniversary and Address objects will be given a reverse, backwards relationship too; by default it'll be called person_set but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.

1. Install NuGet Package Manager

The existing answers will fail if the string is empty or only has one character. Options:

String substring = str.length() > 2 ? str.substring(str.length() - 2) : str;

or

String substring = str.substring(Math.max(str.length() - 2, 0));

That's assuming that str is non-null, and that if there are fewer than 2 characters, you just want the original string.

(I know this is old but I wanted to post this for people like me who stumble upon it in the future) I personally just use this python code to decode base64 strings:

print open("FILE-WITH-STRING", "rb").read().decode("base64")

So you can run it in a bash script like this:

python -c 'print open("FILE-WITH-STRING", "rb").read().decode("base64")' > outputfile
file -i outputfile

twneale has also pointed out an even simpler solution: base64 -d So you can use it like this:

cat "FILE WITH STRING" | base64 -d > OUTPUTFILE
#Or You Can Do This
echo "STRING" | base64 -d > OUTPUTFILE

That will save the decoded string to outputfile and then attempt to identify file-type using either the file tool or you can try TrID. The following command will decode the string into a file and then use TrID to automatically identify the file's type and add the extension.

echo "STRING" | base64 -d > OUTPUTFILE; trid -ce OUTPUTFILE

jQuery .height will return you the height of the element. It doesn't need CSS definition as it determines the computed height.

DEMO

You can use .height(), .innerHeight() or outerHeight() based on what you need.

.height() - returns the height of element excludes padding, border and margin.

.innerHeight() - returns the height of element includes padding but excludes border and margin.

.outerHeight() - returns the height of the div including border but excludes margin.

.outerHeight(true) - returns the height of the div including margin.

Check below code snippet for live demo. :)

$(function() {_x000D_
  var $heightTest = $('#heightTest');_x000D_
  $heightTest.html('Div style set as "height: 180px; padding: 10px; margin: 10px; border: 2px solid blue;"')_x000D_
    .append('<p>Height (.height() returns) : ' + $heightTest.height() + ' [Just Height]</p>')_x000D_
    .append('<p>Inner Height (.innerHeight() returns): ' + $heightTest.innerHeight() + ' [Height + Padding (without border)]</p>')_x000D_
    .append('<p>Outer Height (.outerHeight() returns): ' + $heightTest.outerHeight() + ' [Height + Padding + Border]</p>')_x000D_
    .append('<p>Outer Height (.outerHeight(true) returns): ' + $heightTest.outerHeight(true) + ' [Height + Padding + Border + Margin]</p>')_x000D_
});

div { font-size: 0.9em; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_

</div>

You can use this:

bankHoliday= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month

def bank_holiday(month):
   month -= 1#Takes away the numbers from the months, as months start at 1 (January) not at 0. There is no 0 month.
   print(bankHoliday[month])

bank_holiday(int(input("Which month would you like to check out: ")))

If you have an image imported as a resource in your project there is also this:

picPreview.Image = Properties.Resources.ImageName;

Where picPreview is the name of the picture box and ImageName is the name of the file you want to display.

*Resources are located by going to: Project --> Properties --> Resources

With an extension method, you can accomplish this:

public static class Extension
{
    public static string ToStringOrEmpty(this Object value)
    {
        return value == null ? "" : value.ToString();
    }
}

The following would write nothing to the screen and would not thrown an exception:

        string value = null;

        Console.WriteLine(value.ToStringOrEmpty());

Now there are so many ways to apply font one of easiest way is like this, 1) Right-click the res folder go to New > Android resource directory.

2) From Resource type list, select font, and then click OK.

3) Put your font files in the font folder.

Or rather than including at run time, use a script to concatenate prior to upload.

I use Sprockets (I don't know if there are others). You build your JavaScript code in separate files and include comments that are processed by the Sprockets engine as includes. For development you can include files sequentially, then for production to merge them...

• Introducing Sprockets: JavaScript dependency management and concatenation

if ($variable % 6 == 0) {
    echo 'This number is divisible by 6.';
}:

Make divisible by 6:

$variable += (6 - ($variable % 6)) % 6; // faster than while for large divisors

To also remove the trailing newline at the end of the file

python -c "s=open('filename','r').read();open('filename', 'w').write(s.replace('\n',''))"

Oftentimes in Ruby, you don't actually care what the object's class is, per se, you just care that it responds to a certain method. This is known as Duck Typing and you'll see it in all sorts of Ruby codebases.

So in many (if not most) cases, its best to use Duck Typing using #respond_to?(method):

object.respond_to?(:to_i)

If this is just for debugging output, you can use the following to see all the types and values as well.

var_dump($obj);

If you want more control over the output you can use this:

foreach ($obj as $key => $value) {
    echo "$key => $value\n";
}

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

INSTALL_FAILED_VERSION_DOWNGRADE

All Android apps have a package name. The package name uniquely identifies the app on the device. If same packageName as app that's already installed on the device then this error Showing .

1. You can uninstall the application from your device first and then install the fresh one .
2. You could simply increase the number by one each time a new version is released.

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

If the column is a timestamp you can do the following:

        if(fromDate!=null){
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) >= TO_DATE('" + dataFrom + "','dd/mm/yyyy')"));
        }
        if(toDate!=null){               
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) <= TO_DATE('" + dataTo + "','dd/mm/yyyy')"));
        }

        resultDB = criteria.list();

In my mind I have to consider that the foo folder is a stand-alone library. I might want to consider moving it to the Lib\site-packages folder within a python installation. I might want to consider adding a foo.pth file there.

I know it's a library since the ./programs/my_python_program.py contains the following line:

from foo.tasks import my_function

So it doesn't matter that ./programs is a sibling folder to ./foo. It's the fact that my_python_program.py is run as a script like this:

python ./programs/my_python_program.py

If you're doing it via CMD as you say, then you can just enter the command like so:

path\to\your.exe 

which will open it within the same window. For example in C++:

system("path\\to\\your.exe"); // Double backslash for escaping

will open your.exe in the current CMD window. Likewise to start with a new window, just go for:

system("start path\\to\\your.exe");

If you go for the first option, you would have to clear your screen unless you wanted to have the command to open your.exe on the screen still.

I also had problem with refused connection on port 80. I didn't use localhost.

Function is not a property/method from range.

If you want to sum values then use the following:

Range("A1").Value = Application.Sum(Range(Cells(2, 1), Cells(3, 2)))

EDIT:

if you want the formula then use as follows:

Range("A1").Formula = "=SUM(" & Range(Cells(2, 1), Cells(3, 2)).Address(False, False) & ")"

'The two false after Adress is to define the address as relative (A2:B3).
'If you omit the parenthesis clause or write True instead, you can set the address
'as absolute ($A$2:$B$3).

In case you are allways going to use the same range address then you can use as Rory sugested:

Range("A1").Formula ="=Sum(A2:B3)"

The idea is very simple - the query and the data are sent to the database server separately.
That's all.

The root of the SQL injection problem is in the mixing of the code and the data.

In fact, our SQL query is a legitimate program. And we are creating such a program dynamically, adding some data on the fly. Thus, the data may interfere with the program code and even alter it, as every SQL injection example shows it (all examples in PHP/Mysql):

$expected_data = 1;
$query = "SELECT * FROM users where id=$expected_data";

will produce a regular query

SELECT * FROM users where id=1

while this code

$spoiled_data = "1; DROP TABLE users;"
$query        = "SELECT * FROM users where id=$spoiled_data";

will produce a malicious sequence

SELECT * FROM users where id=1; DROP TABLE users;

It works because we are adding the data directly to the program body and it becomes a part of the program, so the data may alter the program, and depending on the data passed, we will either have a regular output or a table users deleted.

While in case of prepared statements we don't alter our program, it remains intact
That's the point.

We are sending a program to the server first

$db->prepare("SELECT * FROM users where id=?");

where the data is substituted by some variable called a parameter or a placeholder.

Note that exactly the same query is sent to the server, without any data in it! And then we're sending the data with the second request, essentially separated from the query itself:

$db->execute($data);

so it can't alter our program and do any harm.
Quite simple - isn't it?

The only thing I have to add that always omitted in the every manual:

Prepared statements can protect only data literals, but cannot be used with any other query part.
So, once we have to add, say, a dynamical identifier - a field name, for example - prepared statements can't help us. I've explained the matter recently, so I won't repeat myself.

Attempting to "convert them all" is the wrong approach to the problem.

Firstly, you need to understand the limitations of what you are trying to do. As others have pointed out, diacritics are there for a reason: they are essentially unique letters in the alphabet of that language with their own meaning / sound etc.: removing those marks is just the same as replacing random letters in an English word. This is before you even go onto consider the Cyrillic languages and other script based texts such as Arabic, which simply cannot be "converted" to English.

If you must, for whatever reason, convert characters, then the only sensible way to approach this it to firstly reduce the scope of the task at hand. Consider the source of the input - if you are coding an application for "the Western world" (to use as good a phrase as any), it would be unlikely that you would ever need to parse Arabic characters. Similarly, the Unicode character set contains hundreds of mathematical and pictorial symbols: there is no (easy) way for users to directly enter these, so you can assume they can be ignored.

By taking these logical steps you can reduce the number of possible characters to parse to the point where a dictionary based lookup / replace operation is feasible. It then becomes a small amount of slightly boring work creating the dictionaries, and a trivial task to perform the replacement. If your language supports native Unicode characters (as Java does) and optimises static structures correctly, such find and replaces tend to be blindingly quick.

This comes from experience of having worked on an application that was required to allow end users to search bibliographic data that included diacritic characters. The lookup arrays (as it was in our case) took perhaps 1 man day to produce, to cover all diacritic marks for all Western European languages.

select monthname(curdate());

OR

select monthname('2013-12-12');

You should run:

composer dump-autoload

and if does not work you should:

re-install composer

As an additional note, there is no need for the for loop because of R's vectorization.

This:

P <- 243.51
t <- 31 / 365
n <- 365

for (r in seq(0.15, 0.22, by = 0.01))    
     A <- P * ((1 + (r/ n))^ (n * t))
     interest <- A - P
}

is equivalent to:

P <- 243.51
t <- 31 / 365
n <- 365
r <- seq(0.15, 0.22, by = 0.01)
A <- P * ((1 + (r/ n))^ (n * t))
interest <- A - P

Because r is a vector, the expression above containing it is performed for all values of the vector.

I would like to clarify a few things due to seemingly conflicting responses (mostly surrounding IEnumerable).

(1) IQueryable extends the IEnumerable interface. (You can send an IQueryable to something which expects IEnumerable without error.)

(2) Both IQueryable and IEnumerable LINQ attempt lazy loading when iterating over the result set. (Note that implementation can be seen in interface extension methods for each type.)

In other words, IEnumerables are not exclusively "in-memory". IQueryables are not always executed on the database. IEnumerable must load things into memory (once retrieved, possibly lazily) because it has no abstract data provider. IQueryables rely on an abstract provider (like LINQ-to-SQL), although this could also be the .NET in-memory provider.

Sample use case

(a) Retrieve list of records as IQueryable from EF context. (No records are in-memory.)

(b) Pass the IQueryable to a view whose model is IEnumerable. (Valid. IQueryable extends IEnumerable.)

(c) Iterate over and access the data set's records, child entities and properties from the view. (May cause exceptions!)

Possible Issues

(1) The IEnumerable attempts lazy loading and your data context is expired. Exception thrown because provider is no longer available.

(2) Entity Framework entity proxies are enabled (the default), and you attempt to access a related (virtual) object with an expired data context. Same as (1).

(3) Multiple Active Result Sets (MARS). If you are iterating over the IEnumerable in a foreach( var record in resultSet ) block and simultaneously attempt to access record.childEntity.childProperty, you may end up with MARS due to lazy loading of both the data set and the relational entity. This will cause an exception if it is not enabled in your connection string.

Solution

• I have found that enabling MARS in the connection string works unreliably. I suggest you avoid MARS unless it is well-understood and explicitly desired.

Execute the query and store results by invoking resultList = resultSet.ToList() This seems to be the most straightforward way of ensuring your entities are in-memory.

In cases where the you are accessing related entities, you may still require a data context. Either that, or you can disable entity proxies and explicitly Include related entities from your DbSet.

For me WORKSPACE was a valid property of the pipeline itself. So when I handed over this to a Groovy method as parameter context from the pipeline script itself, I was able to access the correct value using "... ${context.WORKSPACE} ..."

Yep:

WITH tab (
  bla bla
)

INSERT INTO dbo.prf_BatchItemAdditionalAPartyNos (  BatchID,                                                        AccountNo,
APartyNo,
SourceRowID)    

SELECT * FROM tab

Note that this is for SQL Server, which supports multiple CTEs:

WITH x AS (), y AS () INSERT INTO z (a, b, c) SELECT a, b, c FROM y

Teradata allows only one CTE and the syntax is as your example.

For Windows 7, I just rename the python.exe from the Python 3 folder to python3.exe and add the path into the environment variables. Using that, I can execute python test_script.py and the script runs with Python 2.7 and when I do python3 test_script.py, it runs the script in Python 3.

To add Python 3 to the environment variables, follow these steps -

1. Right Click on My Computer and go to Properties.
2. Go to Advanced System Settings.
3. Click on Environment Variables and edit PATH and add the path to your Python 3 installation directory.

For example,

I just found this when googling to solve the same problem, and had to make a minor change to the solution to make it work in my situation, as I had 2 similar substrings, "Sun" and "Sunstruck" to search for. The offered solution was locating the wrong entry when searching for "Sun". Data in column B

I added another column C, formulaes C1=" "&B1&" " and changed the search to =COUNTIF(B1:B10,"* "&A1&" *")>0, the extra column to allow finding the first of last entry in the concatenated string.

This could be the possible way in which you can directly use LINQ extension methods to check the in clause

var result = _db.Companies.Where(c => _db.CurrentSessionVariableDetails.Select(s => s.CompanyId).Contains(c.Id)).ToList();

Use del.

Example:

>>> text = 'lipsum'
>>> l = list(text)
>>> del l[3:]
>>> ''.join(l)
'sum'

Starting with VB.NET 10, implicit line continuation is supported for a number of syntax elements (see Statements in Visual Basic: Continuing a Statement over Multiple Lines). The concatenation operator (&) is in the list of syntax elements, that support implicit line continuation. Interspersed comments are supported as well, so your second example could be rewritten as:

dim createArticle as string = 
    "Create table article " &
    "    (articleID int " &           ' Comment for articleID
    "    ,articleName varchar(50) " & ' Comment for articleName
    "    )"

Implicit line continuation also works for query operators, with a few restrictions:

Before and after query operators (Aggregate, Distinct, From, Group By, Group Join, Join, Let, Order By, Select, Skip, Skip While, Take, Take While, Where, In, Into, On, Ascending, and Descending). You cannot break a line between the keywords of query operators that are made up of multiple keywords (Order By, Group Join, Take While, and Skip While).

Again, interspersed comments are allowed, so your first example can be rewritten as:

dim results = from a in articles
              where a.articleID = 4  ' articleID - now perfectly legal
              select a.articleName

Here's some code taken from Kirk Evans Blog that demonstrates how to encode an image in C#;

//Load the picture from a file
Image picture = Image.FromFile(@"c:\temp\test.gif");

//Create an in-memory stream to hold the picture's bytes
System.IO.MemoryStream pictureAsStream = new System.IO.MemoryStream();
picture.Save(pictureAsStream, System.Drawing.Imaging.ImageFormat.Gif);

//Rewind the stream back to the beginning
pictureAsStream.Position = 0;
//Get the stream as an array of bytes
byte[] pictureAsBytes = pictureAsStream.ToArray();

//Create an XmlTextWriter to write the XML somewhere... here, I just chose
//to stream out to the Console output stream
System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(Console.Out);

//Write the root element of the XML document and the base64 encoded data
writer.WriteStartElement("w", "binData",
                         "http://schemas.microsoft.com/office/word/2003/wordml");

writer.WriteBase64(pictureAsBytes, 0, pictureAsBytes.Length);

writer.WriteEndElement();
writer.Flush();

I was also facing the same problem. To fix this to the following steps.

1. open Javaws from cmd runnig javaws -viewer command. A new window will open
2. Select the jnlp file which you want and click the run button.
3. Close the javaws viewer window.

The performance is almost a 100% identical. You can check this out by opening the class in Reflector.net

This is the This indexer:

public TValue this[TKey key]
{
    get
    {
        int index = this.FindEntry(key);
        if (index >= 0)
        {
            return this.entries[index].value;
        }
        ThrowHelper.ThrowKeyNotFoundException();
        return default(TValue);
    }
    set
    {
        this.Insert(key, value, false);
    }
}

And this is the Add method:

public void Add(TKey key, TValue value)
{
    this.Insert(key, value, true);
}

I won't post the entire Insert method as it's rather long, however the method declaration is this:

private void Insert(TKey key, TValue value, bool add)

And further down in the function, this happens:

if ((this.entries[i].hashCode == num) && this.comparer.Equals(this.entries[i].key, key))
{
    if (add)
    {
        ThrowHelper.ThrowArgumentException(ExceptionResource.Argument_AddingDuplicate);
    }

Which checks if the key already exists, and if it does and the parameter add is true, it throws the exception.

So for all purposes and intents the performance is the same.

Like a few other mentions, it's all about whether you need the check, for attempts at adding the same key twice.

Sorry for the lengthy post, I hope it's okay.

You most likely want to examine the documentation for T-SQL's CAST and CONVERT functions, located in the documentation here: http://msdn.microsoft.com/en-US/library/ms187928(v=SQL.90).aspx

You will then use one of those functions in your T-SQL query to convert the [idate] column from the database into the datetime format of your liking in the output.

The simple solution would be to use a ItemListener. When the state changes, you would simply check the currently selected item and set the text accordingly

import javax.swing.JTextField;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

public class TestComboBox06 {

    public static void main(String[] args) {
        new TestComboBox06();
    }

    public TestComboBox06() {
        EventQueue.invokeLater(new Runnable() {
            @Override

                }

                JFrame frame = new JFrame("Test");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                frame.add(new TestPane());

                frame.setVisible(true);
            }

        });
    }

    public class TestPane extends JPanel {

        private JComboBox cb;
        private JTextField field;

        public TestPane() {
            cb = new JComboBox(new String[]{"Item 1", "Item 2"});
            field = new JTextField(12);

            add(cb);
            add(field);

            cb.setSelectedItem(null);

            cb.addItemListener(new ItemListener() {
                @Override
                public void itemStateChanged(ItemEvent e) {
                    Object item = cb.getSelectedItem();
                    if ("Item 1".equals(item)) {
                        field.setText("20");
                    } else if ("Item 2".equals(item)) {
                        field.setText("30");
                    }
                }
            });
        }

    }

}

A better solution would be to create a custom object that represents the value to be displayed and the value associated with it...

Updated

Now I no longer have a 10 month chewing on my ankles, I updated the example to use a ListCellRenderer which is a more correct approach then been lazy and overriding toString

                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

                }

                JFrame frame = new JFrame("Test");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());

            cb.setRenderer(new ItemCelLRenderer());
            field = new JTextField(12);

            add(cb);
            add(field);

            cb.setSelectedItem(null);

            cb.addItemListener(new ItemListener() {

                    Item item = (Item)cb.getSelectedItem();
                    field.setText(item.getValue());
                }
            });
        }

    }

        }

        public String getText() {
            return text;
        }

        public String getValue() {
            return value;
        }

    }

    public class ItemCelLRenderer extends DefaultListCellRenderer {

        @Override
        public Component getListCellRendererComponent(JList<?> list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
            super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus); //To change body of generated methods, choose Tools | Templates.
            if (value instanceof Item) {
                setText(((Item)value).getText());
            }
            return this;
        }

    }

}

            mListener.colorChanged("", mCurrentColor);

        // If the touch event is located in the right button, notify the
        // listener with the default color
        if (x > 138 && x < 266 && y > 316 && y < 356)

You need have your private key in your local machine

You need to know the IP address or DNS name of your remote machine or server, you can get this from AWS console

If you are a linux user

• Make sure the permissions on the private key are 600 (chmod 600 <path to private key file>)
• Connect to your machine using ssh (ssh -i <path to private key file> <user>@<IP address or DNS name of remote server>)

If you are a windows user

• Use PuTTy to create the ssh session (http://the.earth.li/~sgtatham/putty/latest/x86/putty-0.66-installer.exe)
• If your private key file is in .pem format convert it into .ppk using puttygen
• Launch PuTTy, set you ppk file, IP address or DNS name of the remote server and start the ssh session

You should use below method-

Math.pow(double a, double b)

Returns the value of the first argument raised to the power of the second argument.

Without adding additional dependencies, this works. You don't need Volley for this. This works using the current version of Kotlin as of Dec 2018: Kotlin 1.3.10

If using Android Studio, you'll need to add this declaration in your AndroidManifest.xml:

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

You should manually declare imports here. The auto-import tool caused me many conflicts.:

import android.os.AsyncTask
import java.io.BufferedReader
import java.io.InputStreamReader
import java.io.OutputStream
import java.io.OutputStreamWriter
import java.net.URL
import java.net.URLEncoder
import javax.net.ssl.HttpsURLConnection

You can't perform network requests on a background thread. You must subclass AsyncTask.

To call the method:

NetworkTask().execute(requestURL, queryString)

Declaration:

private class NetworkTask : AsyncTask<String, Int, Long>() {
    override fun doInBackground(vararg parts: String): Long? {
        val requestURL = parts.first()
        val queryString = parts.last()

        // Set up request
        val connection: HttpsURLConnection = URL(requestURL).openConnection() as HttpsURLConnection
        // Default is GET so you must override this for post
        connection.requestMethod = "POST"
        // To send a post body, output must be true
        connection.doOutput = true
        // Create the stream
        val outputStream: OutputStream = connection.outputStream
        // Create a writer container to pass the output over the stream
        val outputWriter = OutputStreamWriter(outputStream)
        // Add the string to the writer container
        outputWriter.write(queryString)
        // Send the data
        outputWriter.flush()

        // Create an input stream to read the response
        val inputStream = BufferedReader(InputStreamReader(connection.inputStream)).use {
            // Container for input stream data
            val response = StringBuffer()
            var inputLine = it.readLine()
            // Add each line to the response container
            while (inputLine != null) {
                response.append(inputLine)
                inputLine = it.readLine()
            }
            it.close()
            // TODO: Add main thread callback to parse response
            println(">>>> Response: $response")
        }
        connection.disconnect()

        return 0
    }

    protected fun onProgressUpdate(vararg progress: Int) {
    }

    override fun onPostExecute(result: Long?) {
    }
}

Note: The original question was answered already, but I would just like to expand on it with some extras that are relevant to the topic.

Your AIX installation would first be put into volume groups. This is done upon installation.

It will first create rootvg (as in root volume group). This is kinda like your actual hard drive mapped.

This would be equivalent to Disc Management in Windows. AIX wont use up all of that space for its file systems like we tend to do it in consumer Windows machines. Instead there will be a good bit of unallocated space.

To check how much space your rootvg would have you use the following command.

lsvg rootvg

That would stand for list volume group rootvg. This will give you information like the size of physical partitions (PP), Total PPs assigned to the volume group, Free PPs in the volume group, etc. Regardless, the output should be fairly comprehensive.

Next thing you may be interested in, is the file systems on the volume group. Each file system would have certain amount of space given within the volume group it belongs to.

To check what file systems you got on your volume group you use the following command.

lsvgfs rootvg

As in list volume group file systems for rootvg.

You can check how much space each file system has using the following command.

df

I personally like to refine it with flags like -m and -g (in megabytes and gigabytes respectively)

If you have free space available in your volume group, you can assign it to your file systems using the following command.

chfs -a size=+1G /home

As in change file system attribute size by adding 1 G where file system is /home. use man chfs for more instructions. This is a powerful tool. This example is for adjusting size, however you can do more with this command than that.

Sources: http://www.ibm.com/developerworks/aix/library/au-rootvg/ + My own experience working with AIX.

        Console.Write(new string(' ', Console.WindowWidth));
        Console.SetCursorPosition(0, Console.CursorTop - 1);

The options for popen can be used in call

preexec_fn=None, 
close_fds=False, 
shell=False, 
cwd=None, 
env=None, 
universal_newlines=False, 
startupinfo=None, 
creationflags=0

So...

subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml",  "/tmp/video_xml"], stdout=myoutput)

Then you can do what you want with myoutput (which would need to be a file btw).

Also, you can do something closer to a piped output like this.

dmesg | grep hda

would be:

p1 = Popen(["dmesg"], stdout=PIPE)
p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
output = p2.communicate()[0]

There's plenty of lovely, useful info on the python manual page.

I am using rails 6 and Model.all(:order 'columnName DESC') is not working. I have found the correct answer in OrderInRails

This is very simple.

@variable=Model.order('columnName DESC')

Define them more in your css file. Instead of

li.sub-navigation-home-news 

try

#sub-navigation-home li.sub-navigation-home-news 

Check this for more details: http://www.w3.org/TR/CSS2/cascade.html#cascade

Check this question. The correct answer has great explanation on how to terminate threads the right way: Is there any way to kill a Thread in Python?

To make the thread stop on Keyboard Interrupt signal (ctrl+c) you can catch the exception "KeyboardInterrupt" and cleanup before exiting. Like this:

try:
    start_thread()  
except (KeyboardInterrupt, SystemExit):
    cleanup_stop_thread()
    sys.exit()

This way you can control what to do whenever the program is abruptly terminated.

You can also use the built-in signal module that lets you setup signal handlers (in your specific case the SIGINT signal): http://docs.python.org/library/signal.html

Here's another example, showing that operator[] overwrites the value for the key if it exists, but .insert does not overwrite the value if it exists.

void mapTest()
{
  map<int,float> m;


  for( int i = 0 ; i  <=  2 ; i++ )
  {
    pair<map<int,float>::iterator,bool> result = m.insert( make_pair( 5, (float)i ) ) ;

    if( result.second )
      printf( "%d=>value %f successfully inserted as brand new value\n", result.first->first, result.first->second ) ;
    else
      printf( "! The map already contained %d=>value %f, nothing changed\n", result.first->first, result.first->second ) ;
  }

  puts( "All map values:" ) ;
  for( map<int,float>::iterator iter = m.begin() ; iter !=m.end() ; ++iter )
    printf( "%d=>%f\n", iter->first, iter->second ) ;

  /// now watch this.. 
  m[5]=900.f ; //using operator[] OVERWRITES map values
  puts( "All map values:" ) ;
  for( map<int,float>::iterator iter = m.begin() ; iter !=m.end() ; ++iter )
    printf( "%d=>%f\n", iter->first, iter->second ) ;

}

How about the following, where y is the name of your matrix and you are looking for the maximum in the entire matrix:

row(y)[y==max(y)]

if you want to extract the row:

y[row(y)[y==max(y)],] # this returns unsorted rows.

To return sorted rows use:

y[sort(row(y)[y==max(y)]),]

The advantage of this approach is that you can change the conditional inside to anything you need. Also, using col(y) and location of the hanging comma you can also extract columns.

y[,col(y)[y==max(y)]]

To find just the row for the max in a particular column, say column 2 you could use:

seq(along=y[,2])[y[,2]==max(y[,2])]

again the conditional is flexible to look for different requirements.

See Phil Spector's excellent "An introduction to S and S-Plus" Chapter 5 for additional ideas.

Bootstrap 4 (as of alpha 6)

Navbars are built with flexbox! Instead of floats, you’ll need flexbox and margin utilities.

For Align Right use justify-content-end on the collapse div:

<div class="collapse navbar-collapse justify-content-end">
  <ul class="navbar-nav">
    <li class="nav-item active">
      <a class="nav-link" href="#">Home</a>
    </li>
  </ul>
</div>

The client has a pre-seeded store of SSL certificate authorities' public keys. There must be a chain of trust from the certificate for the server up through intermediate authorities up to one of the so-called "root" certificates in order for the server to be trusted.

You can examine and/or alter the list of trusted authorities. Often you do this to add a certificate for a local authority that you know you trust - like the company you work for or the school you attend or what not.

The pre-seeded list can vary depending on which client you use. The big SSL certificate vendors insure that their root certs are in all the major browsers ($$$).

Monkey-in-the-middle attacks are "impossible" unless the attacker has the private key of a trusted root certificate. Since the corresponding certificates are widely deployed, the exposure of such a private key would have serious implications for the security of eCommerce generally. Because of that, those private keys are very, very closely guarded.

Use this code in your php script (first lines)

ini_set('allow_url_fopen',1);

While the accepted answer is very true, just want to point out that AllowTransparency has some downfalls. It does not allow child window controls to show up, ie WebBrowser, and it usually forces software rendering which can have negative performance effects.

There is a better work around though.

When you want to create a window with no border that is resizeable and is able to host a WebBrowser control or a Frame control pointed to a URL you simply couldn't, the contents of said control would show empty.

I found a workaround though; in the Window, if you set the WindowStyle to None, ResizeMode to NoResize (bear with me, you will still be able to resize once done) then make sure you have UNCHECKED AllowsTransparency you will have a static sized window with no border and will show the browser control.

Now, you probably still want to be able to resize right? Well we can to that with a interop call:

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

    [DllImportAttribute("user32.dll")]
    public static extern bool ReleaseCapture();

    //Attach this to the MouseDown event of your drag control to move the window in place of the title bar
    private void WindowDrag(object sender, MouseButtonEventArgs e) // MouseDown
    {
        ReleaseCapture();
        SendMessage(new WindowInteropHelper(this).Handle,
            0xA1, (IntPtr)0x2, (IntPtr)0);
    }

    //Attach this to the PreviewMousLeftButtonDown event of the grip control in the lower right corner of the form to resize the window
    private void WindowResize(object sender, MouseButtonEventArgs e) //PreviewMousLeftButtonDown
    {
        HwndSource hwndSource = PresentationSource.FromVisual((Visual)sender) as HwndSource;
        SendMessage(hwndSource.Handle, 0x112, (IntPtr)61448, IntPtr.Zero);
    }

And voila, A WPF window with no border and still movable and resizable without losing compatibility with with controls like WebBrowser

What really helped me here is spiv's tip (which I would vote up and comment on if I had the reputation points) for getting a stack trace out of an unprepared Python process. Except it didn't work until I modified the gdbinit script. So:

• download http://svn.python.org/projects/python/trunk/Misc/gdbinit and put it in ~/.gdbinit

• edit it, changing PyEval_EvalFrame to PyEval_EvalFrameEx [edit: no longer needed; the linked file already has this change as of 2010-01-14]

• Attach gdb: gdb -p PID

• Get the python stack trace: pystack

This is the easiest way I can figure out:

#!/usr/bin/python3
for i in range(97, 123):
    print("{:c}".format(i), end='')

So, 97 to 122 are the ASCII number equivalent to 'a' to and 'z'. Notice the lowercase and the need to put 123, since it will not be included).

In print function make sure to set the {:c} (character) format, and, in this case, we want it to print it all together not even letting a new line at the end, so end=''would do the job.

The result is this: abcdefghijklmnopqrstuvwxyz

Example with Parse jar...

Add jars to libs folder from Project view … create lib folder if not exists

Copy all jars there...

Add libs to gradle.... in build.gradle file :

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.android.support:design:23.0.0'
    compile 'com.android.support:percent:23.0.0'
    compile 'com.parse.bolts:bolts-android:1.+'
    compile fileTree(dir: 'libs', include: 'Parse-*.jar’)
}

For add all jars of lib folder... change Parse-*.jar to *.jar

You need to use gdb's memory-display commands. The basic one is x, for examine. There's an example on the linked-to page that uses

gdb> x/4xw $sp

to print "four words (w ) of memory above the stack pointer (here, $sp) in hexadecimal (x)". The quotation is slightly paraphrased.

I dont know about SmallSQL, but this works for MSSQL:

IF EXISTS (SELECT * FROM Table1 WHERE Column1='SomeValue')
    UPDATE Table1 SET (...) WHERE Column1='SomeValue'
ELSE
    INSERT INTO Table1 VALUES (...)

Based on the where-condition, this updates the row if it exists, else it will insert a new one.

I hope that's what you were looking for.

This seems to work for me, an example for waiting until the processor reaches a certain percentage

var cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");
int usage = (int) cpuCounter.NextValue();
while (usage == 0 || usage > 80)
{
     Thread.Sleep(250);
     usage = (int)cpuCounter.NextValue();
}

There are three methods of passing an object to a function as a parameter:

1. Pass by reference
2. pass by value
3. adding constant in parameter

Go through the following example:

class Sample
{
public:
    int *ptr;
    int mVar;

    Sample(int i)
    {
        mVar = 4;
        ptr = new int(i);
    }

    ~Sample()
    {
        delete ptr;
    }

    void PrintVal()
    {
        cout << "The value of the pointer is " << *ptr << endl
             << "The value of the variable is " << mVar;
   }
};

void SomeFunc(Sample x)
{
cout << "Say i am in someFunc " << endl;
}


int main()
{

  Sample s1= 10;
  SomeFunc(s1);
  s1.PrintVal();
  char ch;
  cin >> ch;
}

Output:

Say i am in someFunc
The value of the pointer is -17891602
The value of the variable is 4

As the dictionary documentation for python 2 and python 3 would tell you, in python 2 items returns a list, while iteritems returns a iterator.

In python 3, items returns a view, which is pretty much the same as an iterator.

If you are using python 2, you may want to user iteritems if you are dealing with large dictionaries and all you want to do is iterate over the items (not necessarily copy them to a list)

I know this is an old post but as MisterZimbu stated, the color property is defining the values of other properties, as the border-color and, with CSS3, of currentColor.

currentColor is very handy if you want to use the font color for other elements (as the background or custom checkboxes and radios of inner elements for example).

Example:

.element {_x000D_
  color: green;_x000D_
  background: red;_x000D_
  display: block;_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.innerElement1 {_x000D_
  border: solid 10px;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}_x000D_
_x000D_
.innerElement2 {_x000D_
  background: currentColor;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}

<div class="element">_x000D_
  <div class="innerElement1"></div>_x000D_
  <div class="innerElement2"></div>_x000D_
</div>

for powerpoint and pdf files:

<input type="file" placeholder="Do you have a .ppt?" name="pptfile" id="pptfile" accept="application/pdf,application/vnd.ms-powerpoint,application/vnd.openxmlformats-officedocument.presentationml.slideshow,application/vnd.openxmlformats-officedocument.presentationml.presentation"/>

Another convoluted answer which should technically work and is ok for a small number of data points is to plot all your data points as 1 series in order to get your connecting line. Then plot each point as its own series. Then format data labels to display series name for each of the individual data points.

In short it works ok for a small data set or just key points from a data set.

I've been struggling with Dialog animation today, finally got it working using styles, so here is an example.

To start with, the most important thing — I probably had it working 5 different ways today but couldn't tell because... If your devices animation settings are set to "No Animations" (Settings ? Display ? Animation) then the dialogs won't be animated no matter what you do!

The following is a stripped down version of my styles.xml. Hopefully it is self-explanatory. This should be located in res/values.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="PauseDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
    </style>

    <style name="PauseDialogAnimation">
        <item name="android:windowEnterAnimation">@anim/spin_in</item>
        <item name="android:windowExitAnimation">@android:anim/slide_out_right</item>
    </style>
</resources>

The windowEnterAnimation is one of my animations and is located in res\anim. The windowExitAnimation is one of the animations that is part of the Android SDK.

Then when I create the Dialog in my activities onCreateDialog(int id) method I do the following.

Dialog dialog = new Dialog(this, R.style.PauseDialog);

// Setting the title and layout for the dialog
dialog.setTitle(R.string.pause_menu_label);
dialog.setContentView(R.layout.pause_menu);

Alternatively you could set the animations the following way instead of using the Dialog constructor that takes a theme.

Dialog dialog = new Dialog(this);
dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;

If your APP is built using Flutter tools, please examine the codesign info for all pod extensions:

codesign -d --verbose=4 Runner.app/Frameworks/xxx.framework |& grep 'Authority='

The result should be the name of your team.

Run the shell script below to codesign all extensions:

IDENTITY=<prefix of Team ID number>
ENTITLEMENTS=<entitlements.plist>
find Payload/Runner.app -type d -name '*framework' | xargs -I '{}' codesign -s $IDENTITY -f --entitlements $ENTITLEMENTS {} 

And finally don't forget to codesign the Runner.app itself

For one matched character replace, use str_replace:

$string = str_replace(' ', '_', $string);

For all matched character replace, use preg_replace:

$string = preg_replace('/\s+/', '_', $string);

That will work fine, as long as it's in a CSHTML page and not an external JavaScript file.

The Razor template engine doesn't care what it's outputting and does not differentiate between <script> or other tags.

However, you need to encode your strings to prevent XSS attacks.

I solved this issue for myself, I found there's was two files of http-client with different version of other dependent jar files. So there may version were collapsing between libraries files so remove all old/previous libraries files and re-add are jar files from lib folder of this zip file:

The javascript array has a constructor that accepts the length of the array:

let arr = new Array<number>(3);
console.log(arr); // [undefined × 3]

However, this is just the initial size, there's no restriction on changing that:

arr.push(5);
console.log(arr); // [undefined × 3, 5]

Typescript has tuple types which let you define an array with a specific length and types:

let arr: [number, number, number];

arr = [1, 2, 3]; // ok
arr = [1, 2]; // Type '[number, number]' is not assignable to type '[number, number, number]'
arr = [1, 2, "3"]; // Type '[number, number, string]' is not assignable to type '[number, number, number]'

To do it exactly your way? You could use the for...else structure

for url in list_of_urls:
    for url_dict in urls:
        if url_dict['url'] == url:
            url_dict['nbr'] += 1
            break
    else:
        urls.append(dict(url=url, nbr=1))

But it is quite inelegant. Do you really have to store the visited urls as a LIST? If you sort it as a dict, indexed by url string, for example, it would be way cleaner:

urls = {'http://www.google.fr/': dict(url='http://www.google.fr/', nbr=1)}

for url in list_of_urls:
    if url in urls:
        urls[url]['nbr'] += 1
    else:
        urls[url] = dict(url=url, nbr=1)

A few things to note in that second example:

• see how using a dict for urls removes the need for going through the whole urls list when testing for one single url. This approach will be faster.
• Using dict( ) instead of braces makes your code shorter
• using list_of_urls, urls and url as variable names make the code quite hard to parse. It's better to find something clearer, such as urls_to_visit, urls_already_visited and current_url. I know, it's longer. But it's clearer.

And of course I'm assuming that dict(url='http://www.google.fr', nbr=1) is a simplification of your own data structure, because otherwise, urls could simply be:

urls = {'http://www.google.fr':1}

for url in list_of_urls:
    if url in urls:
        urls[url] += 1
    else:
        urls[url] = 1

Which can get very elegant with the defaultdict stance:

urls = collections.defaultdict(int)
for url in list_of_urls:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

after Brew installation , type

brew install ant

This will install Ant on your system. Also you will not need to worry about setting up the path.

Also i have documented on the same - How to Install ANT on Mac OS?

I am getting similar errors recently because recent JDKs (and browsers, and the Linux TLS stack, etc.) refuse to communicate with some servers in my customer's corporate network. The reason of this is that some servers in this network still have SHA-1 certificates.

Please see: https://www.entrust.com/understanding-sha-1-vulnerabilities-ssl-longer-secure/ https://blog.qualys.com/ssllabs/2014/09/09/sha1-deprecation-what-you-need-to-know

If this would be your current case (recent JDK vs deprecated certificate encription) then your best move is to update your network to the proper encription technology.

In case that you should provide a temporal solution for that, please see another answers to have an idea about how to make your JDK trust or distrust certain encription algorithms:

How to force java server to accept only tls 1.2 and reject tls 1.0 and tls 1.1 connections

Anyway I insist that, in case that I have guessed properly your problem, this is not a good solution to the problem and that your network admin should consider removing these deprecated certificates and get a new one.

You can try something like this:

CSS

div {
    width:200px;
    height:200px;
    background: url(img1.png) center center no-repeat;
}

.visited {
    background: url(img2.png) center center no-repeat;
}

HTML

<div href="#" onclick="this.className='visited'">
    <p>Content</p>
</div>

Fiddle

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

This is easy, use this query to find select data from date range between two dates

select * from tabblename WHERE (datecolumn BETWEEN '2018-04-01' AND '2018-04-5')

You just need to rename ib_logfile0 and ib_logfile1 as ib_logfile_0 and ib_logfile_1. Then your problem would be solved.

In angularjs you can create the UI part, service, Directives and all the part of angularjs which represent the UI. It is nice technology to work on.

As any one who new into this technology and want to authenticate the "User" then i suggest to do it with the power of c# web api. for that you can use the OAuth specification which will help you to built a strong security mechanism to authenticate the user. once you build the WebApi with OAuth you need to call that api for token:

var _login = function (loginData) {_x000D_
 _x000D_
        var data = "grant_type=password&username=" + loginData.userName + "&password=" + loginData.password;_x000D_
 _x000D_
        var deferred = $q.defer();_x000D_
 _x000D_
        $http.post(serviceBase + 'token', data, { headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }).success(function (response) {_x000D_
 _x000D_
            localStorageService.set('authorizationData', { token: response.access_token, userName: loginData.userName });_x000D_
 _x000D_
            _authentication.isAuth = true;_x000D_
            _authentication.userName = loginData.userName;_x000D_
 _x000D_
            deferred.resolve(response);_x000D_
 _x000D_
        }).error(function (err, status) {_x000D_
            _logOut();_x000D_
            deferred.reject(err);_x000D_
        });_x000D_
 _x000D_
        return deferred.promise;_x000D_
 _x000D_
    };_x000D_
 

and once you get the token then you request the resources from angularjs with the help of Token and access the resource which kept secure in web Api with OAuth specification.

As According to me while you are using setOnTouchListener om parent or child stop the scrolling of parent as you touch on child else stop scrolling of child as you touch on parent

something along this?

If the DataFrame happens to have an Index or MultiIndex and you want those included as column names too:

names = list(filter(None, df.index.names + df.columns.values.tolist()))

It avoids calling reset_index() which has an unnecessary performance hit for such a simple operation.

I've run into needing this more often because I'm shuttling data from databases where the dataframe index maps to a primary/unique key, but is really just another "column" to me. It would probably make sense for pandas to have a built-in method for something like this (totally possible I've missed it).

There is a simple way.

1. You create an iframe which have for source something like "http://your-domain.com/index.php?url=http://the-site-you-want-to-get.com/unicorn

2. Then, you just get this url with $_GET and display the contents with file_get_contents($_GET['url']);

You will obtain an iframe which has a domain same than yours, then you will be able to use the $("iframe").contents().find("body") to manipulate the content.

Possible duplicate: Is there a maven 2 archetype for spring 3 MVC applications?

That said, I would encourage you to think about making your own archetype. The reason is, no matter what you end up getting from someone else's, you can do better in not that much time, and a decent sized Java project is going to end up making a lot of jar projects.

I tried the above answer - using page.html#ID_name it gave me a 404 page doesn't exist error.

Then instead of using .html, I simply put a slash / before the # and that worked fine. So my example on the sending page between the link tags looks like:

<a href= "http://my website.com/target-page/#El_Chorro">El Chorro</a>

Just use / instead of .html.

Not possible, but you can do:

float f;
int i;
for (i = 0,f = 0.0; i < 5; i++)
{
  //...
}

Or, explicitly limit the scope of f and i using additional brackets:

{
    float f; 
    int i;
    for (i = 0,f = 0.0; i < 5; i++)
    {
       //...
    }
}

If the caller is another project, you should write the config in caller project not the called one.

If you want to make your code work as above, the function printInformation() needs to be declared and implemented as a static function.

If, on the other hand, it is supposed to print information about a specific object, you need to create the object first.

Curl: SSL certificate problem, verify that the CA cert is OK

07 April 2006

When opening a secure url with Curl you may get the following error:

SSL certificate problem, verify that the CA cert is OK

I will explain why the error and what you should do about it.

The easiest way of getting rid of the error would be adding the following two lines to your script . This solution poses a security risk tho.

//WARNING: this would prevent curl from detecting a 'man in the middle' attack
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0); 

Let see what this two parameters do. Quoting the manual.

CURLOPT_SSL_VERIFYHOST: 1 to check the existence of a common name in the SSL peer certificate. 2 to check the existence of a common name and also verify that it matches the hostname provided.

CURLOPT_SSL_VERIFYPEER: FALSE to stop CURL from verifying the peer's certificate. Alternate certificates to verify against can be specified with the CURLOPT_CAINFO option or a certificate directory can be specified with the CURLOPT_CAPATH option. CURLOPT_SSL_VERIFYHOST may also need to be TRUE or FALSE if CURLOPT_SSL_VERIFYPEER is disabled (it defaults to 2). Setting CURLOPT_SSL_VERIFYHOST to 2 (This is the default value) will garantee that the certificate being presented to you have a 'common name' matching the URN you are using to access the remote resource. This is a healthy check but it doesn't guarantee your program is not being decieved.

Enter the 'man in the middle'

Your program could be misleaded into talking to another server instead. This can be achieved through several mechanisms, like dns or arp poisoning ( This is a story for another day). The intruder can also self-sign a certificate with the same 'comon name' your program is expecting. The communication would still be encrypted but you would be giving away your secrets to an impostor. This kind of attack is called 'man in the middle'

Defeating the 'man in the middle'

Well, we need to to verify the certificate being presented to us is good for real. We do this by comparing it against a certificate we reasonable* trust.

If the remote resource is protected by a certificate issued by one of the main CA's like Verisign, GeoTrust et al, you can safely compare against Mozilla's CA certificate bundle which you can get from http://curl.haxx.se/docs/caextract.html

Save the file cacert.pem somewhere in your server and set the following options in your script.

curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, TRUE); 
curl_setopt ($ch, CURLOPT_CAINFO, "pathto/cacert.pem");

Though this is a very old question, I thought it would be nice to update it with recent information;

Since jQuery 1.8 there is a jQuery.parseHTML() function which is now a preferred way of creating elements. Also, there are some issues with parsing HTML via $('(html code goes here)'), fo example official jQuery website mentions the following in one of their release notes:

Relaxed HTML parsing: You can once again have leading spaces or newlines before tags in $(htmlString). We still strongly advise that you use $.parseHTML() when parsing HTML obtained from external sources, and may be making further changes to HTML parsing in the future.

To relate to the actual question, provided example could be translated to:

this.$OuterDiv = $($.parseHTML('<div></div>'))
    .hide()
    .append($($.parseHTML('<table></table>'))
        .attr({ cellSpacing : 0 })
        .addClass("text")
    )
;

which is unfortunately less convenient than using just $(), but it gives you more control, for example you may choose to exclude script tags (it will leave inline scripts like onclick though):

> $.parseHTML('<div onclick="a"></div><script></script>')
[<div onclick=?"a">?</div>?]

> $.parseHTML('<div onclick="a"></div><script></script>', document, true)
[<div onclick=?"a">?</div>?, <script>?</script>?]

Also, here's a benchmark from the top answer adjusted to the new reality:

JSbin Link

jQuery 1.9.1

  $.parseHTML:    88ms
  $($.parseHTML): 240ms
  <div></div>:    138ms
  <div>:          143ms
  createElement:  64ms

It looks like parseHTML is much closer to createElement than $(), but all the boost is gone after wrapping the results in a new jQuery object

Laravel - htmlspecialchars() expects parameter 1 to be string, object given.

thank me latter.........................

when you send or get array from contrller or function but try to print as single value or single variable in laravel blade file so it throws an error

->use any think who convert array into string it work.

solution: 1)run the foreach loop and get single single value and print. 2)The implode() function returns a string from the elements of an array. {{ implode($your_variable,',') }}

implode is best way to do it and its 100% work.

$cfg['Servers'][$i]['auth_type'] = 'HTTP';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '1234';

This solves my problem too. It just logs in automatically.

Use -1 index (negative indices count backward from the end of the array):

a[-1] # => 5
b[-1] # => 6

or Array#last method:

a.last # => 5
b.last # => 6

Depending on your use of Google Analytics data, if you want basic information (such as visits, UI interactions) you might be able to not include analytics.js at all, yet still collect data in GA.

One option may be to instead use the measurement protocol in a cached script. Google Analytics: Measurement Protocol Overview

When you set the transport method explicitly to image, you can see how GA constructs its own image beacons.

ga('set', 'transport', 'image');

https://www.google-analytics.com/r/collect
  ?v={protocol-version}
  &tid={tracking-id}
  &cid={client-id}
  &t={hit-type}
  &dl={location}

You could create your own GET or POST requests with the required payload.

However, if you require a greater level of detail it probably won't be worth your effort.

You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.

And yes you can add header something like this way:

LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

This just means that the git clone copied the files down from github and placed them into a folder. If you try to do it again it will not let you because it can't clone into a folder that has files into it. So if you think the git clone did not complete properly, just delete the folder and do the git clone again. The clone creates a folder the same name as the git repo.

The best way to remember this is that the order of for loop inside the list comprehension is based on the order in which they appear in traditional loop approach. Outer most loop comes first, and then the inner loops subsequently.

So, the equivalent list comprehension would be:

[entry for tag in tags for entry in entries if tag in entry]

In general, if-else statement comes before the first for loop, and if you have just an if statement, it will come at the end. For e.g, if you would like to add an empty list, if tag is not in entry, you would do it like this:

[entry if tag in entry else [] for tag in tags for entry in entries]

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

in my case, this error is raised due to sequence was not created..

CREATE SEQUENCE  J.SOME_SEQ  MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 NOORDER  NOCYCLE ;

In addition to existing answers it is often desired to format the REST output (typically JSON and XML lacks indentation). Try this:

$ curl https://api.twitter.com/1/help/configuration.xml  | xmllint --format -
$ curl https://api.twitter.com/1/help/configuration.json | python -mjson.tool

Tested on Ubuntu 11.0.4/11.10.

Another issue is the desired content type. Twitter uses .xml/.json extension, but more idiomatic REST would require Accept header:

$ curl -H "Accept: application/json"

You can get just the edition name by using the following steps.

• Open "SQL Server Configuration Manager"
• From the List of SQL Server Services, Right Click on "SQL Server (Instance_name)" and Select Properties.
• Select "Advanced" Tab from the Properties window.
• Verify Edition Name from the "Stock Keeping Unit Name"
• Verify Edition Id from the "Stock Keeping Unit Id"
• Verify Service Pack from the "Service Pack Level"
• Verify Version from the "Version"

Sometimes it is not eligible to set height to pixel values. However, it is possible to show vertical scrollbar through setting height of div to 100% and overflow to auto.

Let me show an example:

<div id="content" style="height: 100%; overflow: auto">
  <p>some text</p>
  <ul>
    <li>text</li>
    .....
    <li>text</li>

For Spyder 2.3 which is still installed via apt-get on linux, you change the theme via

Tools > Preferences > Editor > Syntax Color 

The

Tools > Preferences > Syntax Coloring

only shows options for adjusting the different themes, but not actually applying a different theme. Spyder 3.x uses the second option via Syntax Color.

I have often thought that using elseif and dropping through case instances (where the language permits) are code odours, if not smells.

For myself, I have normally found that nested (if/then/else)s usually reflect things better than elseifs, and that for mutually exclusive cases (often where one combination of attributes takes precedence over another), case or something similar is clearer to read two years later.

I think the select statement used by Rexx is a particularly good example of how to do "Case" well (no drop-throughs) (silly example):

Select
    When (Vehicle ¬= "Car") Then
        Name = "Red Bus"
    When (Colour == "Red") Then
        Name = "Ferrari"
    Otherwise
        Name = "Plain old other car"
    End

Oh, and if the optimisation isn't up to it, get a new compiler or language...

This is what I've come up for post order iterator:

    class PostOrderIterator
    implements Iterator<T> {

        private Stack<Node<T>> stack;
        private Node<T> prev;

        PostOrderIterator(Node<T> root) {
            this.stack = new Stack<>();
            recurse(root);
            this.prev = this.stack.peek();
        }

        private void recurse(Node<T> node) {
            if(node == null) {
                return;
            }

            while(node != null) {
                stack.push(node);
                node = node.left;
            }
            recurse(stack.peek().right);
        }

        @Override
        public boolean hasNext() {
            return !stack.isEmpty();
        }

        @Override
        public T next() {
            if(stack.peek().right != this.prev) {
                recurse(stack.peek().right);
            }

            Node<T> next = stack.pop();
            this.prev = next;
            return next.value;
        }
    }

Basically, the main idea is that you should think how the initialization process puts the first item to print on the top of the stack, while the rest of the stack follow the nodes that would have been touched by the recursion. The rest would just then become a lot easier to nail.

Also, from design perspective, PostOrderIterator is an internal class exposed via some factory method of the tree class as an Iterator<T>.

You need to open TCP port 8787 in the ec2 Security Group. Also need to open the same port on the EC2 instance's firewall.

Since Ruby 2.5.0, Array ships with the prepend method (which is just an alias for the unshift method).

I think these pictures are understandable.

Try width: max-content to adjust the width of the div by it's content.

<!DOCTYPE html>
<html>
<head>
<style>
div.ex1 {
  width:500px;
  margin: auto;
  border: 3px solid #73AD21;
}

div.ex2 {
  width: max-content;
  margin: auto;
  border: 3px solid #73AD21;
}
</style>
</head>
<body>

<div class="ex1">This div element has width 500px;</div>
<br>
<div class="ex2">Width by content size</div>

</body>
</html>

I was able to center a view using

At the risk of getting negative marks, I want to suggest that the highest ranking solution (currently the first response) violates the latest SDK Agreement as of Nov 5, 2009. Our application was just rejected for using it. Here's the response from Apple:

"For security reasons, iPhone OS restricts an application (including its preferences and data) to a unique location in the file system. This restriction is part of the security feature known as the application's "sandbox." The sandbox is a set of fine-grained controls limiting an application's access to files, preferences, network resources, hardware, and so on."

The device's phone number is not available within your application's container. You will need to revise your application to read only within your directory container and resubmit your binary to iTunes Connect in order for your application to be reconsidered for the App Store.

This was a real disappointment since we wanted to spare the user having to enter their own phone number.

When Bootstrap Select initializes, it'll build a set of custom divs that run alongside the original <select> element and will typically synchronize state between the two input mechanisms.

Which is to say that one way to handle events on bootstrap select is to listen for events on the original select that it modifies, regardless of who updated it.

Solution 1 - Native Events

Just listen for a change event and get the selected value using javascript or jQuery like this:

$('select').on('change', function(e){
  console.log(this.value,
              this.options[this.selectedIndex].value,
              $(this).find("option:selected").val(),);
});

^{*NOTE: As with any script reliant on the DOM, make sure you wait for the DOM ready event before executing}

Demo in Stack Snippets:

$(function() {_x000D_
_x000D_
  $('select').on('change', function(e){_x000D_
    console.log(this.value,_x000D_
                this.options[this.selectedIndex].value,_x000D_
                $(this).find("option:selected").val(),);_x000D_
  });_x000D_
  _x000D_

Solution 2 - Bootstrap Select Custom Events

As this answer alludes, Bootstrap Select has their own set of custom events, including changed.bs.select which:

fires after the select's value has been changed. It passes through event, clickedIndex, newValue, oldValue.

And you can use that like this:

$("select").on("changed.bs.select", 
      function(e, clickedIndex, newValue, oldValue) {
    console.log(this.value, clickedIndex, newValue, oldValue)
});

Demo in Stack Snippets:

$(function() {_x000D_
_x000D_
  $("select").on("changed.bs.select", _x000D_
        function(e, clickedIndex, newValue, oldValue) {_x000D_
      console.log(this.value, clickedIndex, newValue, oldValue)_x000D_
  });_x000D_
_x000D_
});

ls -lR is to display all files, directories and sub directories of the current directory ls -lR | more is used to show all the files in a flow.

The clean way of stopping the app is:

adb shell am force-stop com.my.app.package

This way you don't have to figure out the process ID.

tabControl1.SelectedTab = MyTab;

If you prefer to use style='{', fmt="{asctime}.{msecs:0<3.0f}" will 0-pad your microseconds to three places for consistency.

You have conditions that are mutually exclusive - if meta_key is 'first_name', it can't also be 'yearofpassing'. Most likely you need your AND's to be OR's:

$result = mysql_query("SELECT user_id FROM wp_usermeta 
WHERE (meta_key = 'first_name' AND meta_value = '$us_name') 
OR (meta_key = 'yearofpassing' AND meta_value = '$us_yearselect') 
OR (meta_key = 'u_city' AND meta_value = '$us_reg') 
OR (meta_key = 'us_course' AND meta_value = '$us_course')")

Enable VS Code preference Auto Attach from File -> Preferences -> Settings -> Search for Auto Attach and set it On, open the console (ctrl + *) or from the menu Terminal -> New Terminal, set a breakpoint in your code, type in the command

node --inspect <name of your file>

This will start the debugging and the VS Code will show the Debug menu.

Note: Auto Attach is also very helpful if you are working with node cluster worker threads.

As mentioned earlier, document.forms works too.

function setFocusToTextBox( _element ) {
  document.forms[ 'myFormName' ].elements[ _element ].focus();
}

setFocusToTextBox( 0 );
// sets focus on first element of the form

For printing I don't set any width and remove any obstacles which keep your print layout from having a dynamic width. Meaning if you make your browser window smaller and smaller, no content is cut/hidden but the document just gets longer. Like this, you can be sure that the rest will be handled by the printer/pdf-creator.

What about elements with a fixed width such as images or tables?

Images

Options I can think of:

• scale images down in your print CSS to a width which you can assume will fit in any case, use pt not px (but print will need more points/unit anyways, so this should hardly be a problem)
• exclude from being printed

Tables

• remove the fixed width
• use landscape if you really have tables with loads of information
• don't use tables for layout purposes
• exclude from being printed
• extract content, print it as paragraphs

http://www.intensivstation.ch/en/css/print/

or any other google result for combinations of: CSS, print, media, layout

If you are on Mac run use root privilege

sudo npm install gulp-cli --global

To check if it's installed run

gulp -v

CLI version: 2.2.0 (The output)

Local version: Unknown

Well, I cant find any SecondaryInstaller.exe to stop in task manager and even I dont have any AV rather then Windows Defender so I found something else..
I stopped windows Update from elevated cmd by writing command net stop muauserv and it worked for me...
The update will Retry again for KB2664825 so run the code again in cmd..(because the service starts automatically)

Keep trying and its done for me...!!

For OSX

• into ~/.bash_profile add:

  export ANDROID_HOME="/path/to/android-sdk-macosx"
  export PATH="$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools:$PATH"
  

  and then execute it in terminal to take effect immediately;

• into /etc/sudoers add: (you can use console: sudo visudo)

  Defaults        env_keep += "ANDROID_HOME"
  

  since the building process has to start with sudo and Node's process.env get the respective variables.

You can use the files from debug folder,however if you look at app debug informations with some inspection software,you can clearly see "Symbols File Name" which can reveals not wanted informations in path to the original exe file.

" Hello " , " This " , "is ", "Sorting ", "Example"

First of all you provided spaces in " Hello " and " This ", spaces have a lower value than alphabetic characters in Unicode, so it gets printed first. (The rest of the characters were sorted alphabetically).

Now upper case letters have a lower value than lower case letter in Unicode, so "Example" and "Sorting" gets printed, then at last "is " which has the highest value.

Here is an example of data binding with AngularJS, using an input field. I will explain later

HTML Code

<div ng-app="myApp" ng-controller="myCtrl" class="formInput">
     <input type="text" ng-model="watchInput" Placeholder="type something"/>
     <p>{{watchInput}}</p> 
</div>

AngularJS Code

myApp = angular.module ("myApp", []);
myApp.controller("myCtrl", ["$scope", function($scope){
  //Your Controller code goes here
}]);

As you can see in the example above, AngularJS uses ng-model to listen and watch what happens on HTML elements, especially on input fields. When something happens, do something. In our case, ng-model is bind to our view, using the mustache notation {{}}. Whatever is typed inside the input field is displayed on the screen instantly. And that's the beauty of data binding, using AngularJS in its simplest form.

Hope this helps.

See a working example here on Codepen

jquery:

$('div.animalcontent').hide();
$('div').hide();
$('p.animal').bind('mouseover', function() {
    $('div.animalcontent').fadeOut();
    $('#'+$(this).attr('id')+'content').fadeIn();
});  

html:

<p class='animal' id='dog'>dog url</p><div id='dogcontent' class='animalcontent'>Doggiecontent!</div>
<p class='animal' id='cat'>cat url</p><div id='catcontent' class='animalcontent'>Pussiecontent!</div>
<p class='animal' id='snake'>snake url</p><div id='snakecontent'class='animalcontent'>Snakecontent!</div>

-edit-

yeah sure, here you go -- JSFiddle

On the Mac version I was getting the error when trying to run JSON-Clojure.json.clj, which is the script to export a database table to JSON. To get it to work I had to download the latest Clojure JAR from http://clojure.org/ and then right-click on PHPStorm app in the Finder and "Show Package Contents". Then go to Contents in there. Then open the lib folder, and see a bunch of .jar files. Copy the clojure-1.8.0.jar file from the unzipped archive I downloaded from clojure.org into the aforementioned lib folder inside the PHPStorm.app/Contents/lib. Restart the app. Now it freaking works.

EDIT: You also have to put the JSR-223 script engine into PHPStorm.app/Contents/lib. It can be built from https://github.com/ato/clojure-jsr223 or downloaded from https://www.dropbox.com/s/jg7s0c41t5ceu7o/clojure-jsr223-1.5.1.jar?dl=0 .

Use moment-timezone

moment(date).tz('Europe/Berlin').format(format)

Before being able to access a particular timezone, you will need to load it like so (or using alternative methods described here)

moment.tz.add('Europe/Berlin|CET CEST CEMT|-10 -20 -30')

I had almost just as same error with my Ruby on Rails application running postgresql(mac). This worked for me:

brew services restart postgresql

Just cast each character to an int:

for (int i = 0; i < str.length; i++)  
  Console.Write(((int)str[i]).ToString());

There are many ways to do this with the following being one of them:

if [ -z "$1" ]

This succeeds if $1 is null or unset

That is a self-invoking anonymous function.

Check out the W3Schools explanation of a self-invoking function.

Function expressions can be made "self-invoking".

A self-invoking expression is invoked (started) automatically, without being called.

Function expressions will execute automatically if the expression is followed by ().

You cannot self-invoke a function declaration.

tldr; jsFiddle Demo

This functionality is not possible with an alert. However, you could use a div

function tempAlert(msg,duration)
{
 var el = document.createElement("div");
 el.setAttribute("style","position:absolute;top:40%;left:20%;background-color:white;");
 el.innerHTML = msg;
 setTimeout(function(){
  el.parentNode.removeChild(el);
 },duration);
 document.body.appendChild(el);
}

Use this like this:

tempAlert("close",5000);

You would because defining an IList or an ICollection would open up for other implementations of your interfaces.

You might want to have an IOrderRepository that defines a collection of orders in either a IList or ICollection. You could then have different kinds of implementations to provide a list of orders as long as they conform to "rules" defined by your IList or ICollection.

sleep(1.0/24.0)

As to your follow up question if that's the best way: No, you could get not-so-smooth framerates because the rendering of each frame might not take the same amount of time.

You could try one of these solutions:

• Use a timer which fires 24 times a second with the drawing code.
• Create as many frames as possible, create the motion based on the time passed, not per frame.

You can use $_SERVER['HTTP_REFERER'] this will give you whole URL for example:

suppose you want to get url of site name www.example.com then $_SERVER['HTTP_REFERER'] will give you https://www.example.com

Yes, indeed. The datepicker has the maxdate property that you can set when you initialize it.

Here's the codez

$("#datepicker").datepicker({ maxDate: new Date, minDate: new Date(2007, 6, 12) });

Test Data

DECLARE @Table1 TABLE(ID INT, Value INT)
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400)

Query

SELECT  ID
       ,STUFF((SELECT ', ' + CAST(Value AS VARCHAR(10)) [text()]
         FROM @Table1 
         WHERE ID = t.ID
         FOR XML PATH(''), TYPE)
        .value('.','NVARCHAR(MAX)'),1,2,' ') List_Output
FROM @Table1 t
GROUP BY ID

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

SQL Server 2017 and Later Versions

If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:

DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);


SELECT ID , STRING_AGG([Value], ', ') AS List_Output
FROM @Table1
GROUP BY ID;

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

There are two kinds of input value: field's property and field's html attribute.

If you use keyup event and field.value you shuld get current value of the field. It's not the case when you use field.getAttribute('value') which would return what's in the html attribute (value=""). The property represents what's been typed into the field and changes as you type, while attribute doesn't change automatically (you can change it using field.setAttribute method).

Try to use this code example:

$("#TextAreaID1").bind('input propertychange', function () {
    var maxLength = 4000;
    if ($(this).val().length > maxLength) {
        $(this).val($(this).val().substring(0, maxLength));
    }
});

Just in case it may help people having this issue while using nodejs apps that produce heavy logging, a colleague solved this issue by piping the standard output(s) to a file.

Setting Up the database

public class DatabaseHelper extends SQLiteOpenHelper {
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "database_name";

    // Table Names
    private static final String DB_TABLE = "table_image";

    // column names
    private static final String KEY_NAME = "image_name";
    private static final String KEY_IMAGE = "image_data";

    // Table create statement
    private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+ 
                       KEY_NAME + " TEXT," + 
                       KEY_IMAGE + " BLOB);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        // creating table
        db.execSQL(CREATE_TABLE_IMAGE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // on upgrade drop older tables
        db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);

        // create new table
        onCreate(db);
    }
}

Insert in the Database:

public void addEntry( String name, byte[] image) throws SQLiteException{
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues cv = new  ContentValues();
    cv.put(KEY_NAME,    name);
    cv.put(KEY_IMAGE,   image);
    database.insert( DB_TABLE, null, cv );
}

Retrieving data:

 byte[] image = cursor.getBlob(1);

Note:

1. Before inserting into database, you need to convert your Bitmap image into byte array first then apply it using database query.
2. When retrieving from database, you certainly have a byte array of image, what you need to do is to convert byte array back to original image. So, you have to make use of BitmapFactory to decode.

Below is an Utility class which I hope could help you:

public class DbBitmapUtility {

    // convert from bitmap to byte array
    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }

    // convert from byte array to bitmap
    public static Bitmap getImage(byte[] image) {
        return BitmapFactory.decodeByteArray(image, 0, image.length);
    }
}

Further reading
If you are not familiar how to insert and retrieve into a database, go through this tutorial.

1. Generate an access token with never expire date, and select all the options available.
2. Remove the existing SSH keys.
3. Clone the repo with the https instead of ssh.
4. Use the username but use the generated access token instead of password.

alternatively you can set remote to http by using this command in the existing repo, and use this command git remote set-url origin https://gitlab.com/[username]/[repo-name].git

You want to do the check for undefined first. If you do it the other way round, it will generate an error if the array is undefined.

if (array === undefined || array.length == 0) {
    // array empty or does not exist
}

Update

This answer is getting a fair amount of attention, so I'd like to point out that my original answer, more than anything else, addressed the wrong order of the conditions being evaluated in the question. In this sense, it fails to address several scenarios, such as null values, other types of objects with a length property, etc. It is also not very idiomatic JavaScript.

The foolproof approach
Taking some inspiration from the comments, below is what I currently consider to be the foolproof way to check whether an array is empty or does not exist. It also takes into account that the variable might not refer to an array, but to some other type of object with a length property.

if (!Array.isArray(array) || !array.length) {
  // array does not exist, is not an array, or is empty
  // ? do not attempt to process array
}

To break it down:

1. Array.isArray(), unsurprisingly, checks whether its argument is an array. This weeds out values like null, undefined and anything else that is not an array.
   Note that this will also eliminate array-like objects, such as the arguments object and DOM NodeList objects. Depending on your situation, this might not be the behavior you're after.

2. The array.length condition checks whether the variable's length property evaluates to a truthy value. Because the previous condition already established that we are indeed dealing with an array, more strict comparisons like array.length != 0 or array.length !== 0 are not required here.

The pragmatic approach
In a lot of cases, the above might seem like overkill. Maybe you're using a higher order language like TypeScript that does most of the type-checking for you at compile-time, or you really don't care whether the object is actually an array, or just array-like.

In those cases, I tend to go for the following, more idiomatic JavaScript:

if (!array || !array.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or, more frequently, its inverse:

if (array && array.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

With the introduction of the optional chaining operator (Elvis operator) in ECMAScript 2020, this can be shortened even further:

if (!array?.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or the opposite:

if (array?.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

Your DOS command 2> nul

Read page Using command redirection operators. Besides the "2>" construct mentioned by Tanuki Software, it lists some other useful combinations.

The first one should work:

undefined
> a.split("\n");
[ 'test.js', 'again.js' ]

What would be useful here would be a LIKE ANY predicate as is available in PostgreSQL

SELECT * 
FROM tbl
WHERE my_col LIKE ANY (ARRAY['%val1%', '%val2%', '%val3%', ...])

Unfortunately, that syntax is not available in Oracle. You can expand the quantified comparison predicate using OR, however:

SELECT * 
FROM tbl
WHERE my_col LIKE '%val1%' OR my_col LIKE '%val2%' OR my_col LIKE '%val3%', ...

Or alternatively, create a semi join using an EXISTS predicate and an auxiliary array data structure (see this question for details):

SELECT *
FROM tbl t
WHERE EXISTS (
  SELECT 1
  -- Alternatively, store those values in a temp table:
  FROM TABLE (sys.ora_mining_varchar2_nt('%val1%', '%val2%', '%val3%'/*, ...*/))
  WHERE t.my_col LIKE column_value
)

For true full-text search, you might want to look at Oracle Text: http://www.oracle.com/technetwork/database/enterprise-edition/index-098492.html

You can manually set xticks (and yticks) using pyplot.xticks:

import matplotlib.pyplot as plt
import numpy as np

x = np.array([0,1,2,3])
y = np.array([20,21,22,23])
my_xticks = ['John','Arnold','Mavis','Matt']
plt.xticks(x, my_xticks)
plt.plot(x, y)
plt.show()

After jQuery 1.7 the preferred methods are .on() and .off()

Sean's answer shows an example.

Now Deprecated:

Use the jQuery functions .live() and .die(). Available in jQuery 1.3.x

From the docs:

To display each paragraph's text in an alert box whenever it is clicked:

$("p").live("click", function(){
  alert( $(this).text() );
});

Also, the livequery plugin does this and has support for more events.

Well, unfortunately it seems that one cannot place custom markers and draw (and obtain coordinates) directly from maps.google.com if one is anonymous/not logged in (as it was possible some years ago, if I recall correctly). Still, thanks to the answers here, I managed to make a combination of examples that has both the Google Places search, and allows drawing via the drawing library, and dumps coordinates upon making a selection of any type of shape (including coordinates for polygon) that can be copypasted; the code is here:

• https://gist.github.com/anonymous/68b8f6a586c512cfc768#file-gmaps-drawing-tools-places-htm

This is how it looks like:

(The Places markers are handled separately, and can be deleted via the DEL "button" by the search input form element; "curpos" shows the current center [position] and zoom level of the map viewport).
