Seems to suppress the funding issue.

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

You can only use

     Object& return_Object();

if the object returned has a greater scope than the function. For example, you can use it if you have a class where it is encapsulated. If you create an object in your function, use pointers. If you want to modify an existing object, pass it as an argument.

  class  MyClass{
      private:
        Object myObj;

      public:
         Object& return_Object() {
            return myObj;
         }

         Object* return_created_Object() {
            return new Object();
         }

         bool modify_Object( Object& obj) {
            //  obj = myObj; return true; both possible
            return obj.modifySomething() == true;
         }
   };

You can try this ! This should work on windows machines.

for /F "usebackq tokens=1,2,3 delims=-" %%I IN (`echo %date%`) do echo "%%I" "%%J" "%%K"

there's another one not mentioned here - nice thin - if you need that kind of look for your project: ╳

╳ or decimal: ╳

The answer is not efficiency. Non-reentrant mutexes lead to better code.

Example: A::foo() acquires the lock. It then calls B::bar(). This worked fine when you wrote it. But sometime later someone changes B::bar() to call A::baz(), which also acquires the lock.

Well, if you don't have recursive mutexes, this deadlocks. If you do have them, it runs, but it may break. A::foo() may have left the object in an inconsistent state before calling bar(), on the assumption that baz() couldn't get run because it also acquires the mutex. But it probably shouldn't run! The person who wrote A::foo() assumed that nobody could call A::baz() at the same time - that's the entire reason that both of those methods acquired the lock.

The right mental model for using mutexes: The mutex protects an invariant. When the mutex is held, the invariant may change, but before releasing the mutex, the invariant is re-established. Reentrant locks are dangerous because the second time you acquire the lock you can't be sure the invariant is true any more.

If you are happy with reentrant locks, it is only because you have not had to debug a problem like this before. Java has non-reentrant locks these days in java.util.concurrent.locks, by the way.

I just found this out by trying to see if my event was attached....

if you do :

item.onclick

it will return "null"

but if you do:

item.hasOwnProperty('onclick')

then it is "TRUE"

so I think that when you use "addEventListener" to add event handlers, the only way to access it is through "hasOwnProperty". I wish I knew why or how but alas, after researching, I haven't found an explanation.

You'll want to set a "list-style" via CSS, and give it a color: value. Example:

ul.colored {list-style: color: green;}

Can I check - do you mean a rectangular array ([,])or a jagged array ([][])?

It is quite easy to sort a jagged array; I have a discussion on that here. Obviously in this case the Comparison<T> would involve a column instead of sorting by ordinal - but very similar.

Sorting a rectangular array is trickier... I'd probably be tempted to copy the data out into either a rectangular array or a List<T[]>, and sort there, then copy back.

Here's an example using a jagged array:

static void Main()
{  // could just as easily be string...
    int[][] data = new int[][] { 
        new int[] {1,2,3}, 
        new int[] {2,3,4}, 
        new int[] {2,4,1} 
    }; 
    Sort<int>(data, 2); 
} 
private static void Sort<T>(T[][] data, int col) 
{ 
    Comparer<T> comparer = Comparer<T>.Default;
    Array.Sort<T[]>(data, (x,y) => comparer.Compare(x[col],y[col])); 
} 

For working with a rectangular array... well, here is some code to swap between the two on the fly...

static T[][] ToJagged<T>(this T[,] array) {
    int height = array.GetLength(0), width = array.GetLength(1);
    T[][] jagged = new T[height][];

    for (int i = 0; i < height; i++)
    {
        T[] row = new T[width];
        for (int j = 0; j < width; j++)
        {
            row[j] = array[i, j];
        }
        jagged[i] = row;
    }
    return jagged;
}
static T[,] ToRectangular<T>(this T[][] array)
{
    int height = array.Length, width = array[0].Length;
    T[,] rect = new T[height, width];
    for (int i = 0; i < height; i++)
    {
        T[] row = array[i];
        for (int j = 0; j < width; j++)
        {
            rect[i, j] = row[j];
        }
    }
    return rect;
}
// fill an existing rectangular array from a jagged array
static void WriteRows<T>(this T[,] array, params T[][] rows)
{
    for (int i = 0; i < rows.Length; i++)
    {
        T[] row = rows[i];
        for (int j = 0; j < row.Length; j++)
        {
            array[i, j] = row[j];
        }
    }
}

I had the same problem. When i was trying and testing on a browser on my PC machine i didn't have the "not a function" error, but when i tried on a virtual machine the error was popping. I'd solved it by adding the slick files on my web server and adding the urls of the css and js files from my web server to my html. Before that i was pulling the css and js from CDN.

You must remove the system.out.println message from below the return, like this:

public Item anyItem()
{
    randomGenerator = new Random();
    int index = randomGenerator.nextInt(catalogue.size());
    Item it = catalogue.get(index);
    System.out.println("Managers choice this week" + it + "our recommendation to you");
    return it;
}

the return statement basically says the function will now end. anything included beyond the return statement that is also in scope of it will result in the behavior you experienced

The fcntl module is just used for locking the pinning file, so assuming you don't try multiple access, this can be an acceptable workaround. Place this module in your sys.path, and it should just work as the official fcntl module.

Try using this module for development/testing purposes only in windows.

def fcntl(fd, op, arg=0):
    return 0

def ioctl(fd, op, arg=0, mutable_flag=True):
    if mutable_flag:
        return 0
    else:
        return ""

def flock(fd, op):
    return

def lockf(fd, operation, length=0, start=0, whence=0):
    return

You're not reading the file content:

my_file_contents = f.read()

See the docs for further infos

You could, without calling read() or readlines() loop over your file object:

f = open('goodlines.txt')
for line in f:
    print(line)

If you want a list out of it (without \n as you asked)

my_list = [line.rstrip('\n') for line in f]

Currently, the eyedropper tool is not working in my version of Chrome (as described above), though it worked for me in the past. I hear it is being updated in the latest version of Chrome.

However, I'm able to grab colors easily in Firefox.

1. Open page in Firefox
2. Hamburger Menu -> Web Developer -> Eyedropper
3. Drag eyedropper tool over the image... Click.
   Color is copied to your clipboard, and eyedropper tool goes away.
4. Paste color code

In case you cannot get the eyedropper tool to work in Chrome, this is a good work around.
I also find it easier to access :-)

• Short version of (correct) tzaman answer will be (for fresh SVN)

  svn switch ^/branches/v1p2p3
  

• --relocate switch is deprecated anyway, when it needed you'll have to use svn relocate command

• Instead of creating snapshot-branch (ReadOnly) you can use tags (conventional RO labels for history)

On Windows, the caret character (^) must be escaped:

svn switch ^^/branches/v1p2p3

I developed a way to catch all error types in PHP (almost all)! I have no sure about E_CORE_ERROR (I think will not works only for that error)! But, for other fatal errors (E_ERROR, E_PARSE, E_COMPILE...) works fine using only one error handler function! There goes my solution:

Put this following code on your main file (index.php):

<?php
    define('E_FATAL',  E_ERROR | E_USER_ERROR | E_PARSE | E_CORE_ERROR |
            E_COMPILE_ERROR | E_RECOVERABLE_ERROR);

    define('ENV', 'dev');

    // Custom error handling vars
    define('DISPLAY_ERRORS', TRUE);
    define('ERROR_REPORTING', E_ALL | E_STRICT);
    define('LOG_ERRORS', TRUE);

    register_shutdown_function('shut');

    set_error_handler('handler');

    // Function to catch no user error handler function errors...
    function shut(){

        $error = error_get_last();

        if($error && ($error['type'] & E_FATAL)){
            handler($error['type'], $error['message'], $error['file'], $error['line']);
        }

    }

    function handler( $errno, $errstr, $errfile, $errline ) {

        switch ($errno){

            case E_ERROR: // 1 //
                $typestr = 'E_ERROR'; break;
            case E_WARNING: // 2 //
                $typestr = 'E_WARNING'; break;
            case E_PARSE: // 4 //
                $typestr = 'E_PARSE'; break;
            case E_NOTICE: // 8 //
                $typestr = 'E_NOTICE'; break;
            case E_CORE_ERROR: // 16 //
                $typestr = 'E_CORE_ERROR'; break;
            case E_CORE_WARNING: // 32 //
                $typestr = 'E_CORE_WARNING'; break;
            case E_COMPILE_ERROR: // 64 //
                $typestr = 'E_COMPILE_ERROR'; break;
            case E_CORE_WARNING: // 128 //
                $typestr = 'E_COMPILE_WARNING'; break;

                $typestr = 'E_USER_ERROR'; break;
            case E_USER_WARNING: // 512 //
                $typestr = 'E_USER_WARNING'; break;
            case E_USER_NOTICE: // 1024 //
                $typestr = 'E_USER_NOTICE'; break;
            case E_STRICT: // 2048 //
                $typestr = 'E_STRICT'; break;
            case E_RECOVERABLE_ERROR: // 4096 //
                $typestr = 'E_RECOVERABLE_ERROR'; break;
            case E_DEPRECATED: // 8192 //
                $typestr = 'E_DEPRECATED'; break;

                $typestr = 'E_USER_DEPRECATED'; break;
        }

        $message =
            '<b>' . $typestr .

            '</b> on line <b>' . $errline .
            '</b><br/>';

        if(($errno & E_FATAL) && ENV === 'production'){

            header('Location: 500.html');
            header('Status: 500 Internal Server Error');

        }

        if(!($errno & ERROR_REPORTING))
            return;

        if(DISPLAY_ERRORS)
            printf('%s', $message);

        //Logging error on php file error log...
        if(LOG_ERRORS)
            error_log(strip_tags($message), 0);
    }

    ob_start();

    @include 'content.php';

    ob_end_flush();

If you don't want to use numpy, you could use the list of lists concept. To create any 2D array, just use the following syntax:

  mat = [[input() for i in range (col)] for j in range (row)]

and then enter the values you want.

The following should suffice:

[^ ]

If you want to expand that to anything but white-space (line breaks, tabs, spaces, hard spaces):

[^\s]

or

\S  # Note this is a CAPITAL 'S'!

Most modern desktop browsers such as Chrome, Mozilla and Internet Explorer support images encoded as data URL. But there are problems displaying data URLs in some mobile browsers: Android Stock Browser and Dolphin Browser won't display embedded JPEGs.

I reccomend you to use the following tools for online base64 encoding/decoding:

• Encode to Base64 format

• Decode from Base64 format

Check the "Format as Data URL" option to format as a Data URL.

The input() function returns a string which may contain a "list of numbers". You should have understood that the numbers[2] operation returns the third element of an iterable. A string is an iterable, but an iterable of characters, which isn't what you want - you want to average the numbers in the input string.

So there are two things you have to do before you can get to the averaging shown by garyprice:

1. convert the input string into something containing just the number strings (you don't want the spaces between the numbers)
2. convert each number string into an integer

Hint for step 1: you have to split the input string into non-space substrings.

Step 2 (convert string to integer) should be easy to find with google.

HTH

For anyone else finding this - its worth noting that you can set the key value in the input name. Thanks to the answer in POSTing Form Fields with same Name Attribute you also can interplay strings or integers without quoting.

The answers assume that you don't mind the key value coming back for PHP however you can set name=[yourval] (string or int) which then allows you to refer to an existing record.

No need to use the filter or tag in template. Just use format_html() to translate variable to html and Django will automatically turn escape off for you variable.

format_html("<h1>Hello</h1>")

As an addendum: this can also occur if you update a nuget package that was used to generate a fakes assembly. Say you install V1.0 of a nuget package and create a fakes assembly "fakeLibrary.1.0.0.0.Fakes". Next, you update to the newest version of the nuget package, say v1.1 which added a new method to an interface. The Fakes library is still looking for v1.0 of the library. Simply remove the fake assembly and regenerate it. If that was the issue, this will probably fix it.

All the responses here have been way too complex. You know that the first of the current month is the current date but with 01 as the date. You can just use YEAR() and MONTH() to build the month date by inputting the NOW() method. Here's the solution:

select * from table_name 
where date between CONCAT_WS('-', YEAR( NOW() ), MONTH( NOW() ), '01') and DATE( NOW() )

CONCAT_WS() joins a series of strings with a separator (a dash in this case). So if today is 2020-08-28, YEAR( NOW() ) = '2020' and MONTH( NOW() ) = '08' and then you just need to append '01' at the end.

Voila!

The easiest way to do this would be to put a link on your column headers, pointing to the same page. In the query string, put a variable so that you know what they clicked on, and then use ORDER BY in your SQL query to perform the ordering.

The HTML would look like this:

<th><a href="mypage.php?sort=type">Type:</a></th>
<th><a href="mypage.php?sort=desc">Description:</a></th>
<th><a href="mypage.php?sort=recorded">Recorded Date:</a></th>
<th><a href="mypage.php?sort=added">Added Date:</a></th>

And in the php code, do something like this:

<?php

$sql = "SELECT * FROM MyTable";

if ($_GET['sort'] == 'type')
{
    $sql .= " ORDER BY type";
}
elseif ($_GET['sort'] == 'desc')
{
    $sql .= " ORDER BY Description";
}
elseif ($_GET['sort'] == 'recorded')
{
    $sql .= " ORDER BY DateRecorded";
}
elseif($_GET['sort'] == 'added')
{
    $sql .= " ORDER BY DateAdded";
}

$>

Notice that you shouldn't take the $_GET value directly and append it to your query. As some user could got to MyPage.php?sort=; DELETE FROM MyTable;

Multiple Non-query example if anyone is interested.

using (OdbcConnection DbConnection = new OdbcConnection("ConnectionString"))
{
  DbConnection.Open();
  using (OdbcCommand DbCommand = DbConnection.CreateCommand())
  {
    DbCommand.CommandText = "INSERT...";
    DbCommand.Parameters.Add("@Name", OdbcType.Text, 20).Value = "name";
    DbCommand.ExecuteNonQuery();

    DbCommand.Parameters.Clear();
    DbCommand.Parameters.Add("@Name", OdbcType.Text, 20).Value = "name2";
    DbCommand.ExecuteNonQuery();
  }
}

Initializing the Canvas like below works for TypeScript/Angular solutions.

const canvas = <HTMLCanvasElement> document.getElementById("htmlElemId"); 

const context = canvas.getContext("2d"); 

Quick answer:
A child scope normally prototypically inherits from its parent scope, but not always. One exception to this rule is a directive with scope: { ... } -- this creates an "isolate" scope that does not prototypically inherit. This construct is often used when creating a "reusable component" directive.

As for the nuances, scope inheritance is normally straightfoward... until you need 2-way data binding (i.e., form elements, ng-model) in the child scope. Ng-repeat, ng-switch, and ng-include can trip you up if you try to bind to a primitive (e.g., number, string, boolean) in the parent scope from inside the child scope. It doesn't work the way most people expect it should work. The child scope gets its own property that hides/shadows the parent property of the same name. Your workarounds are

1. define objects in the parent for your model, then reference a property of that object in the child: parentObj.someProp
2. use $parent.parentScopeProperty (not always possible, but easier than 1. where possible)
3. define a function on the parent scope, and call it from the child (not always possible)

New AngularJS developers often do not realize that ng-repeat, ng-switch, ng-view, ng-include and ng-if all create new child scopes, so the problem often shows up when these directives are involved. (See this example for a quick illustration of the problem.)

This issue with primitives can be easily avoided by following the "best practice" of always have a '.' in your ng-models – watch 3 minutes worth. Misko demonstrates the primitive binding issue with ng-switch.

Having a '.' in your models will ensure that prototypal inheritance is in play. So, use

<input type="text" ng-model="someObj.prop1">

<!--rather than
<input type="text" ng-model="prop1">`
-->

JavaScript Prototypal Inheritance

Also placed on the AngularJS wiki: https://github.com/angular/angular.js/wiki/Understanding-Scopes

It is important to first have a solid understanding of prototypal inheritance, especially if you are coming from a server-side background and you are more familiar with class-ical inheritance. So let's review that first.

Suppose parentScope has properties aString, aNumber, anArray, anObject, and aFunction. If childScope prototypically inherits from parentScope, we have:

(Note that to save space, I show the anArray object as a single blue object with its three values, rather than an single blue object with three separate gray literals.)

If we try to access a property defined on the parentScope from the child scope, JavaScript will first look in the child scope, not find the property, then look in the inherited scope, and find the property. (If it didn't find the property in the parentScope, it would continue up the prototype chain... all the way up to the root scope). So, these are all true:

childScope.aString === 'parent string'
childScope.anArray[1] === 20
childScope.anObject.property1 === 'parent prop1'
childScope.aFunction() === 'parent output'

Suppose we then do this:

childScope.aString = 'child string'

The prototype chain is not consulted, and a new aString property is added to the childScope. This new property hides/shadows the parentScope property with the same name. This will become very important when we discuss ng-repeat and ng-include below.

Suppose we then do this:

childScope.anArray[1] = '22'
childScope.anObject.property1 = 'child prop1'

The prototype chain is consulted because the objects (anArray and anObject) are not found in the childScope. The objects are found in the parentScope, and the property values are updated on the original objects. No new properties are added to the childScope; no new objects are created. (Note that in JavaScript arrays and functions are also objects.)

Suppose we then do this:

childScope.anArray = [100, 555]
childScope.anObject = { name: 'Mark', country: 'USA' }

The prototype chain is not consulted, and child scope gets two new object properties that hide/shadow the parentScope object properties with the same names.

Takeaways:

• If we read childScope.propertyX, and childScope has propertyX, then the prototype chain is not consulted.
• If we set childScope.propertyX, the prototype chain is not consulted.

One last scenario:

delete childScope.anArray
childScope.anArray[1] === 22  // true

We deleted the childScope property first, then when we try to access the property again, the prototype chain is consulted.

Angular Scope Inheritance

The contenders:

• The following create new scopes, and inherit prototypically: ng-repeat, ng-include, ng-switch, ng-controller, directive with scope: true, directive with transclude: true.
• The following creates a new scope which does not inherit prototypically: directive with scope: { ... }. This creates an "isolate" scope instead.

Note, by default, directives do not create new scope -- i.e., the default is scope: false.

ng-include

Suppose we have in our controller:

$scope.myPrimitive = 50;
$scope.myObject    = {aNumber: 11};

And in our HTML:

<script type="text/ng-template" id="/tpl1.html">
<input ng-model="myPrimitive">
</script>
<div ng-include src="'/tpl1.html'"></div>

<script type="text/ng-template" id="/tpl2.html">
<input ng-model="myObject.aNumber">
</script>
<div ng-include src="'/tpl2.html'"></div>

Each ng-include generates a new child scope, which prototypically inherits from the parent scope.

Typing (say, "77") into the first input textbox causes the child scope to get a new myPrimitive scope property that hides/shadows the parent scope property of the same name. This is probably not what you want/expect.

Typing (say, "99") into the second input textbox does not result in a new child property. Because tpl2.html binds the model to an object property, prototypal inheritance kicks in when the ngModel looks for object myObject -- it finds it in the parent scope.

We can rewrite the first template to use $parent, if we don't want to change our model from a primitive to an object:

<input ng-model="$parent.myPrimitive">

Typing (say, "22") into this input textbox does not result in a new child property. The model is now bound to a property of the parent scope (because $parent is a child scope property that references the parent scope).

For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via scope properties $parent, $$childHead and $$childTail. I normally don't show these scope properties in the diagrams.

For scenarios where form elements are not involved, another solution is to define a function on the parent scope to modify the primitive. Then ensure the child always calls this function, which will be available to the child scope due to prototypal inheritance. E.g.,

// in the parent scope
$scope.setMyPrimitive = function(value) {
     $scope.myPrimitive = value;
}

Here is a sample fiddle that uses this "parent function" approach. (The fiddle was written as part of this answer: https://stackoverflow.com/a/14104318/215945.)

See also https://stackoverflow.com/a/13782671/215945 and https://github.com/angular/angular.js/issues/1267.

ng-switch

ng-switch scope inheritance works just like ng-include. So if you need 2-way data binding to a primitive in the parent scope, use $parent, or change the model to be an object and then bind to a property of that object. This will avoid child scope hiding/shadowing of parent scope properties.

See also AngularJS, bind scope of a switch-case?

ng-repeat

Ng-repeat works a little differently. Suppose we have in our controller:

$scope.myArrayOfPrimitives = [ 11, 22 ];
$scope.myArrayOfObjects    = [{num: 101}, {num: 202}]

And in our HTML:

<ul><li ng-repeat="num in myArrayOfPrimitives">
       <input ng-model="num">
    </li>
<ul>
<ul><li ng-repeat="obj in myArrayOfObjects">
       <input ng-model="obj.num">
    </li>
<ul>

For each item/iteration, ng-repeat creates a new scope, which prototypically inherits from the parent scope, but it also assigns the item's value to a new property on the new child scope. (The name of the new property is the loop variable's name.) Here's what the Angular source code for ng-repeat actually is:

childScope = scope.$new();  // child scope prototypically inherits from parent scope
...
childScope[valueIdent] = value;  // creates a new childScope property

If item is a primitive (as in myArrayOfPrimitives), essentially a copy of the value is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence child scope num) does not change the array the parent scope references. So in the first ng-repeat above, each child scope gets a num property that is independent of the myArrayOfPrimitives array:

This ng-repeat will not work (like you want/expect it to). Typing into the textboxes changes the values in the gray boxes, which are only visible in the child scopes. What we want is for the inputs to affect the myArrayOfPrimitives array, not a child scope primitive property. To accomplish this, we need to change the model to be an array of objects.

So, if item is an object, a reference to the original object (not a copy) is assigned to the new child scope property. Changing the child scope property's value (i.e., using ng-model, hence obj.num) does change the object the parent scope references. So in the second ng-repeat above, we have:

(I colored one line gray just so that it is clear where it is going.)

This works as expected. Typing into the textboxes changes the values in the gray boxes, which are visible to both the child and parent scopes.

ng-controller

Nesting controllers using ng-controller results in normal prototypal inheritance, just like ng-include and ng-switch, so the same techniques apply. However, "it is considered bad form for two controllers to share information via $scope inheritance" -- http://onehungrymind.com/angularjs-sticky-notes-pt-1-architecture/ A service should be used to share data between controllers instead.

(If you really want to share data via controllers scope inheritance, there is nothing you need to do. The child scope will have access to all of the parent scope properties. See also Controller load order differs when loading or navigating)

directives

1. default (scope: false) - the directive does not create a new scope, so there is no inheritance here. This is easy, but also dangerous because, e.g., a directive might think it is creating a new property on the scope, when in fact it is clobbering an existing property. This is not a good choice for writing directives that are intended as reusable components.
2. scope: true - the directive creates a new child scope that prototypically inherits from the parent scope. If more than one directive (on the same DOM element) requests a new scope, only one new child scope is created. Since we have "normal" prototypal inheritance, this is like ng-include and ng-switch, so be wary of 2-way data binding to parent scope primitives, and child scope hiding/shadowing of parent scope properties.
3. scope: { ... } - the directive creates a new isolate/isolated scope. It does not prototypically inherit. This is usually your best choice when creating reusable components, since the directive cannot accidentally read or modify the parent scope. However, such directives often need access to a few parent scope properties. The object hash is used to set up two-way binding (using '=') or one-way binding (using '@') between the parent scope and the isolate scope. There is also '&' to bind to parent scope expressions. So, these all create local scope properties that are derived from the parent scope. Note that attributes are used to help set up the binding -- you can't just reference parent scope property names in the object hash, you have to use an attribute. E.g., this won't work if you want to bind to parent property parentProp in the isolated scope: <div my-directive> and scope: { localProp: '@parentProp' }. An attribute must be used to specify each parent property that the directive wants to bind to: <div my-directive the-Parent-Prop=parentProp> and scope: { localProp: '@theParentProp' }.
   Isolate scope's __proto__ references Object. Isolate scope's $parent references the parent scope, so although it is isolated and doesn't inherit prototypically from the parent scope, it is still a child scope.
   For the picture below we have
   <my-directive interpolated="{{parentProp1}}" twowayBinding="parentProp2"> and
   scope: { interpolatedProp: '@interpolated', twowayBindingProp: '=twowayBinding' }
   Also, assume the directive does this in its linking function: scope.someIsolateProp = "I'm isolated"
   
   For more information on isolate scopes see http://onehungrymind.com/angularjs-sticky-notes-pt-2-isolated-scope/
4. transclude: true - the directive creates a new "transcluded" child scope, which prototypically inherits from the parent scope. The transcluded and the isolated scope (if any) are siblings -- the $parent property of each scope references the same parent scope. When a transcluded and an isolate scope both exist, isolate scope property $$nextSibling will reference the transcluded scope. I'm not aware of any nuances with the transcluded scope.
   For the picture below, assume the same directive as above with this addition: transclude: true
   

This fiddle has a showScope() function that can be used to examine an isolate and transcluded scope. See the instructions in the comments in the fiddle.

Summary

There are four types of scopes:

1. normal prototypal scope inheritance -- ng-include, ng-switch, ng-controller, directive with scope: true
2. normal prototypal scope inheritance with a copy/assignment -- ng-repeat. Each iteration of ng-repeat creates a new child scope, and that new child scope always gets a new property.
3. isolate scope -- directive with scope: {...}. This one is not prototypal, but '=', '@', and '&' provide a mechanism to access parent scope properties, via attributes.
4. transcluded scope -- directive with transclude: true. This one is also normal prototypal scope inheritance, but it is also a sibling of any isolate scope.

For all scopes (prototypal or not), Angular always tracks a parent-child relationship (i.e., a hierarchy), via properties $parent and $$childHead and $$childTail.

Diagrams were generated with graphviz "*.dot" files, which are on github. Tim Caswell's "Learning JavaScript with Object Graphs" was the inspiration for using GraphViz for the diagrams.

You might consider writing an iterator instead, which allows you to use normal 'for' loop syntax like '++'. I searched and found a similar question answered here on StackOverflow which gives pointers on making DateTime iterable.

Since you have updated your label client side, you'll need a post-back in order for you're server side code to reflect the changes.

If you do not know how to do this, here is how I've gone about it in the past.

Create a hidden field:

<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />

Create a button that has both client side and server side functions attached to it. You're client side function will populate your hidden field, and the server side will read it. Be sure you're client side is being called first.

<asp:Button ID="_Submit" runat="server" Text="Submit Button" OnClientClick="TestSubmit();" OnClick="_Submit_Click" />

Javascript Client Side Function:

function TestSubmit() {
              try {

             var message = "Message to Pass";
             document.getElementById('__EVENTTARGET').value = message;

           } catch (err) {
              alert(err.message);

          }

      }

C# Server Side Function

protected void _Submit_Click(object sender, EventArgs e)
{
     // Hidden Value after postback
     string hiddenVal= Request.Form["__EVENTTARGET"];
}

Hope this helps!

You can use the URL facade which lets you do calls to the URL generator

So you can do:

URL::to('/');

You can also use the application container:

$app->make('url')->to('/');
$app['url']->to('/');
App::make('url')->to('/');

Or inject the UrlGenerator:

<?php
namespace Vendor\Your\Class\Namespace;

use Illuminate\Routing\UrlGenerator;

class Classname
{
    protected $url;

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

    public function methodName()
    {
        $this->url->to('/');
    }
}

Since std::string in C++ is mutable you can use that. It has a += operator and an append function.

If you need to append numerical data use the std::to_string functions.

If you want even more flexibility in the form of being able to serialise any object to a string then use the std::stringstream class. But you'll need to implement your own streaming operator functions for it to work with your own custom classes.

I would also recommend the Tao Framework. But one additional note:

Take a look at these tutorials: http://www.taumuon.co.uk/jabuka/

Unfortunately, the most common use of <a href="#"> is by lazy programmers who want clickable non-hyperlink javascript-coded elements that behave like anchors, but they can't be arsed to add cursor: pointer; or :hover styles to a class for their non-hyperlink elements, and are additionally too lazy to set href to javascript:void(0);.

The problem with this is that one <a href="#" onclick="some_function();"> or another inevitably ends up with a javascript error, and an anchor with an onclick javascript error always ends up following its href. Normally this ends up being an annoying jump to the top of the page, but in the case of sites using <base>, <a href="#"> is handled as <a href="[base href]/#">, resulting in an unexpected navigation. If any logable errors are being generated, you won't see them in the latter case unless you enable persistent logs.

If an anchor element is used as a non-anchor it should have its href set to javascript:void(0); for the sake of graceful degradation.

I just wasted two days debugging a random unexpected page redirect that should have simply refreshed the page, and finally tracked it down to a function raising the click event of an <a href="#">. Replacing the # with javascript:void(0); fixed it.

The first thing I'm doing Monday is purging the project of all instances of <a href="#">.

And you can use %stylesheets% (assetic feature) tag:

{% stylesheets
    "@MainBundle/Resources/public/colorbox/colorbox.css"
    "%kerner.root_dir%/Resources/css/main.css"
%}
<link type="text/css" rel="stylesheet" media="all" href="{{ asset_url }}" />
{% endstylesheets %}

You can write path to css as parameter (%parameter_name%).

More about this variant: http://symfony.com/doc/current/cookbook/assetic/asset_management.html

To those who failed in getting this to work (As myself!) after trying all the answers here, just make sure Clip Subviews is not enabled at the Attributes inspector...

The message you received is common when you have ruby 2.0.0p0 (2013-02-24) on top of Windows.

The message "DL is deprecated, please use Fiddle" is not an error; it's only a warning.

The source is the Deprecation notice for DL introduced some time ago in dl.rb ( see revisions/37910 ).

On Windows the lib/ruby/site_ruby/2.0.0/readline.rb file still requires dl.rb so the warning message comes out when you require 'irb' ( because irb requires 'readline' ) or when anything else wants to require 'readline'.

You can open readline.rb with your favorite text editor and look up the code ( near line 4369 ):

    if RUBY_VERSION < '1.9.1'
      require 'Win32API'
    else
      require 'dl'
      class Win32API
        DLL = {}

We can always hope for an improvement to work out this deprecation in future releases of Ruby.

EDIT: For those wanting to go deeper about Fiddle vs DL, let it be said that their purpose is to dynamically link external libraries with Ruby; you can read on the ruby-doc website about DL or Fiddle.

Time Zone

To format an Instant a time-zone is required. Without a time-zone, the formatter does not know how to convert the instant to human date-time fields, and therefore throws an exception.

The time-zone can be added directly to the formatter using withZone().

DateTimeFormatter formatter =
    DateTimeFormatter.ofLocalizedDateTime( FormatStyle.SHORT )
                     .withLocale( Locale.UK )
                     .withZone( ZoneId.systemDefault() );

If you specifically want an ISO-8601 format with no explicit time-zone (as the OP asked), with the time-zone implicitly UTC, you need

DateTimeFormatter.ISO_LOCAL_DATE_TIME.withZone(ZoneId.from(ZoneOffset.UTC))

Generating String

Now use that formatter to generate the String representation of your Instant.

Instant instant = Instant.now();
String output = formatter.format( instant );

Dump to console.

System.out.println("formatter: " + formatter + " with zone: " + formatter.getZone() + " and Locale: " + formatter.getLocale() );
System.out.println("instant: " + instant );
System.out.println("output: " + output );

When run.

formatter: Localized(SHORT,SHORT) with zone: US/Pacific and Locale: en_GB
instant: 2015-06-02T21:34:33.616Z
output: 02/06/15 14:34

Check out the help command:

svn help copy

  -r [--revision] arg      : ARG (some commands also take ARG1:ARG2 range)
                             A revision argument can be one of:
                                NUMBER       revision number
                                '{' DATE '}' revision at start of the date
                                'HEAD'       latest in repository
                                'BASE'       base rev of item's working copy
                                'COMMITTED'  last commit at or before BASE
                                'PREV'       revision just before COMMITTED

To actually specify this on the command line using your example:

svn copy -r123 http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Where 123 would be the revision number in trunk you want to copy. As others have noted, you can also use the @ syntax. I prefer the clearer separation of the revision # from the URL, personally.

As noted in the help, you can replace a revision # with certain words as well:

svn copy -rPREV http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Would copy the "revision just before COMMITTED".

Looking at the web I find some simple way to style scrollbars.

This is THE guy! http://almaer.com/blog/creating-custom-scrollbars-with-css-how-css-isnt-great-for-every-task

    width: 10px;
    height: 13px;
}

::-webkit-scrollbar-button:vertical {
    background-color: silver;
    border: 1px solid gray;
}

/* Turn on single button up on top, and down on bottom */
::-webkit-scrollbar-button:start:decrement,
::-webkit-scrollbar-button:end:increment {

You could first import your json data in a Python dictionnary :

data = json.loads(elevations)

Then modify data on the fly :

for result in data['results']:
    result[u'lat']=result[u'location'][u'lat']
    result[u'lng']=result[u'location'][u'lng']
    del result[u'location']

Rebuild json string :

elevations = json.dumps(data)

Finally :

pd.read_json(elevations)

You can, also, probably avoid to dump data back to a string, I assume Panda can directly create a DataFrame from a dictionnary (I haven't used it since a long time :p)

You can try below code. Check http://api.jquery.com/jquery.grep/

var blockedTile = new Array("118", "67", "190", "43", "135", "520");
var searchNumber = "11878";
arr = jQuery.grep(blockedTile, function( i ) {
  return i === searchNumber;
});
if(arr.length){ console.log('Present'); }else{ console.log('Not Present'); }

check arr.length if it's more than 0 means string is present else it's not present.

it's also a good thing to make sure you have the right import

I had an issue like that and I found out that the bean was using

    javax.faces.view.ViewScoped;
                 ^

instead of

    javax.faces.bean.ViewScoped;
                 ^

Check up the date ISO standard; kind of like this:

yyyy.MM.ddThh:mm

It becomes 2008.11.20T22:18.

I had this problem. It took me ages to figure out. I had people over my shoulder to help. We rebuilt, cleaned and restarted Visual studio and this didn't fix it. We removed and re-added the references...

All to no avail.... Until!

The solution to my problem was that my class declaration was spelt incorrectly.

Before you start judging me harshly, allow me to explain why it wasn't stupid, and also why this mistake could be made by even the most intelligent of programmers.

Since the mistake was early on in the name, it wasn't appearing in the intellisense class listing when I began typing.

e.g.

Class name: Message.cs

Declaration:

public class Massage
{
    //code here

}

At a glance and in a small font, Massage looks identical to Message.

Typing M listed too many classes, so I typed e, which didn't appear in the mistyped version, which gave the impression that the class wasn't being picked up by the compiler.

you can follow the below command to install using the wheel file at your local

pip install /users/arpansaini/Downloads/h5py-3.0.0-cp39-cp39-macosx_10_9_x86_64.whl

By far the simplest solution:

if id -u "$user" >/dev/null 2>&1; then
    echo 'user exists'
else
    echo 'user missing'
fi

The >/dev/null 2>&1 can be shortened to &>/dev/null in Bash.

Option 1 - Easier & Persistent

Running Visual Studio Code as Administrator should do the trick.

If you're on Windows you can:

1. Right click the shortcut or app/exe
2. Go to properties
3. Compatibility tab
4. Check "Run this program as an administrator"

Make sure you have all other instances of VS Code closed and then try to run as Administrator. The electron framework likes to stall processes when closing them so it's best to check your task manager and kill the remaining processes.

• https://visualstudio.uservoice.com/forums/293070-visual-studio-code/suggestions/8915236-visual-code-w-terminal-integrated-and-super-admin
• https://github.com/Microsoft/vscode/issues/7407

Option 2 - More like Sudo

If for some weird reason this is not running your commands as an Administrator you can try the runas command. Microsoft: runas command

• runas /user:Administrator myCommand
• runas "/user:First Last" "my command"

• Just don't forget to put double quotes around anything that has a space in it.
• Also it's quite possible that you have never set the password on the Administrator account, as it will ask you for the password when trying to run the command. You can always use an account without the username of Administrator if it has administrator access rights/permissions.

Another way is to reverse before and after cut:

$ echo ab:cd:ef | rev | cut -d: -f1 | rev
ef

This makes it very easy to get the last but one field, or any range of fields numbered from the end.

Good and convenient solution:

In your ViewController:

@IBOutlet weak var label: LabelButton!

override func viewDidLoad() {
    super.viewDidLoad()

    self.label.onClick = {
        // TODO
    }
}

You can place this in your ViewController or in another .swift file(e.g. CustomView.swift):

@IBDesignable class LabelButton: UILabel {
    var onClick: () -> Void = {}
    override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
        onClick()
    }
}

In Storyboard select Label and on right pane in "Identity Inspector" in field class select LabelButton.

Don't forget to enable in Label Attribute Inspector "User Interaction Enabled"

With the verify parameter you can provide a custom certificate authority bundle

requests.get(url, verify=path_to_bundle_file)

From the docs:

You can pass verify the path to a CA_BUNDLE file with certificates of trusted CAs. This list of trusted CAs can also be specified through the REQUESTS_CA_BUNDLE environment variable.

This is another method in addition to my previous answer at Can I add jars to maven 2 build classpath without installing them?

This will get around the limit when using multi-module builds especially if the downloaded JAR is referenced in child projects outside of the parent. This also reduces the setup work by creating the POM and the SHA1 files as part of the build. It also allows the file to reside anywhere in the project without fixing the names or following the maven repository structure.

This uses the maven-install-plugin. For this to work, you need to set up a multi-module project and have a new project representing the build to install files into the local repository and ensure that one is first.

You multi-module project pom.xml would look like this:

<packaging>pom</packaging>
<modules>
<!-- The repository module must be first in order to ensure
     that the local repository is populated -->
    <module>repository</module>
    <module>... other modules ...</module>
</modules>

The repository/pom.xml file will then contain the definitions to load up the JARs that are part of your project. The following are some snippets of the pom.xml file.

<artifactId>repository</artifactId>
<packaging>pom</packaging>

The pom packaging prevents this from doing any tests or compile or generating any jar file. The meat of the pom.xml is in the build section where the maven-install-plugin is used.

I would suggest you use Wireshark.

Steps:

1. Install Wireshark.
2. Select the network connection that you are using for the calls(for eg, select the Wifi if you are using it)
3. There will be many requests and responses, close extra applications.
4. Usually the requests are in green color, once you spot your request, copy the destination address and use the filter on top by typing ip.dst==52.187.182.185 by putting the destination address.

You can make use of other filtering techniques mentioned here to get specific traffic.

This is what I came up with to easily view all data values:

var dataItems = "";_x000D_
$.each(data, function (index, itemData) {_x000D_
    dataItems += index + ": " + itemData + "\n";_x000D_
});_x000D_
console.log(dataItems);

I too have struggled with this new pagespeed metric.

Although I have found no practical way to get my score back up to %100 there are a few things I have found helpful.

Combining all css into one file helped a lot. All my sites are back up to %95 - %98.

The only other thing I could think of was to inline all the necessary css (which appears to be most of it - at least for my pages) on the first page to get the sweet high score. Although it may help your speed score this will probably make your page load slower though.

"var" means the compiler will determine the explicit type of the variable, based on usage. For example,

var myVar = new Connection();

would give you a variable of type Connection.

C++14

std::string great = "Hello"s + " World"; // concatenation easy!

Answer on the question:

auto fname = ""s + name + ".txt";

You can use the shuffle function from the random module like this:

import random

my_list = list(xrange(1,100)) # list of integers from 1 to 99
                              # adjust this boundaries to fit your needs
random.shuffle(my_list)
print my_list # <- List of unique random numbers

Note here that the shuffle method doesn't return any list as one may expect, it only shuffle the list passed by reference.

def flatten_it(d):
    if isinstance(d, list) or isinstance(d, tuple):
        return tuple([flatten_it(item) for item in d])

Old question, but another "pure razor" answer would be:

@Html.CheckBoxFor(model => model.As, htmlAttributes: new { @checked = true} )

You can use require with the path to the global module directory as an argument.

require('/path/to/global/node_modules/the_module');

On my mac, I use this:

require('/usr/local/lib/node_modules/the_module');

I've come up with a different approach that could convert any struct without the hassle of fixing length, however the resulting byte array would have a little bit more overhead.

Here is a sample struct:

[StructLayout(LayoutKind.Sequential)]
public class HelloWorld
{
    public MyEnum enumvalue;
    public string reqtimestamp;
    public string resptimestamp;
    public string message;
    public byte[] rawresp;
}

As you can see, all those structures would require adding the fixed length attributes. Which could often ended up taking up more space than required. Note that the LayoutKind.Sequential is required, as we want reflection to always gives us the same order when pulling for FieldInfo. My inspiration is from TLV Type-Length-Value. Let's have a look at the code:

public static byte[] StructToByteArray<T>(T obj)
{
    using (MemoryStream ms = new MemoryStream())
    {
        FieldInfo[] infos = typeof(T).GetFields(BindingFlags.Public | BindingFlags.Instance);
        foreach (FieldInfo info in infos)
        {
            BinaryFormatter bf = new BinaryFormatter();
            using (MemoryStream inms = new MemoryStream()) {

                bf.Serialize(inms, info.GetValue(obj));
                byte[] ba = inms.ToArray();
                // for length
                ms.Write(BitConverter.GetBytes(ba.Length), 0, sizeof(int));

                // for value
                ms.Write(ba, 0, ba.Length);
            }
        }

        return ms.ToArray();
    }
}

The above function simply uses the BinaryFormatter to serialize the unknown size raw object, and I simply keep track of the size as well and store it inside the output MemoryStream too.

public static void ByteArrayToStruct<T>(byte[] data, out T output)
{
    output = (T) Activator.CreateInstance(typeof(T), null);
    using (MemoryStream ms = new MemoryStream(data))
    {
        byte[] ba = null;
        FieldInfo[] infos = typeof(T).GetFields(BindingFlags.Public | BindingFlags.Instance);
        foreach (FieldInfo info in infos)
        {
            // for length
            ba = new byte[sizeof(int)];
            ms.Read(ba, 0, sizeof(int));

            // for value
            int sz = BitConverter.ToInt32(ba, 0);
            ba = new byte[sz];
            ms.Read(ba, 0, sz);

            BinaryFormatter bf = new BinaryFormatter();
            using (MemoryStream inms = new MemoryStream(ba))
            {
                info.SetValue(output, bf.Deserialize(inms));
            }
        }
    }
}

When we want to convert it back to its original struct we simply read the length back and directly dump it back into the BinaryFormatter which in turn dump it back into the struct.

These 2 functions are generic and should work with any struct, I've tested the above code in my C# project where I have a server and a client, connected and communicate via NamedPipeStream and I forward my struct as byte array from one and to another and converted it back.

I believe my approach might be better, since it doesn't fix length on the struct itself and the only overhead is just an int for every fields you have in your struct. There are also some tiny bit overhead inside the byte array generated by BinaryFormatter, but other than that, is not much.

How To Read XML Data into a DataSet by Using Visual C# .NET contains some details. Basically, you can use the overloaded DataSet method ReadXml to get the data into a DataSet. Your XML data will be in the first DataTable there.

There is also a DataTable.ReadXml method.

It's not a big deal, it's pretty easy to switch between them. MSTest being integrated isn't a big deal either, just grab testdriven.net.

Like the previous person said pick a mocking framework, my favourite at the moment is Moq.

The solution in UIKeyboardTypeNumberPad and missing return key works great but only if there are no other non-number pad text fields on the screen.

I took that code and turned it into an UIViewController that you can simply subclass to make number pads work. You will need to get the icons from the above link.

Steps to remove index.php from url for your wordpress website.

1. Check you should have mod_rewrite enabled at your server. To check whether it's enabled or not - Create 1 file phpinfo.php at your root folder with below command.

 <?php
   phpinfo?();
 ?>

Now run this file - www.yoursite.com/phpinfo.php and it will show mod_rewrite at Load modules section. If not enabled then perform below commands at your terminal.

sudo a2enmod rewrite
sudo service apache2 restart

2. Make sure your .htaccess is existing in your WordPress root folder, if not create one .htaccess file Paste this code at your .htaccess file :-

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.php [L]
</IfModule>  

3. Further make permission of .htaccess to 666 so that it become writable and now you can do changes in your wordpress permalinks.

4. Now go to Settings -> permalinks -> and change to your needed url format. Remove this code /index.php/%year%/%monthnum%/%day%/%postname%/ and insert this code on Custom Structure: /%postname%/

5. If still not succeeded then check your hosting, mine was digitalocean server, so I cleared it myself

Edited the file /etc/apache2/sites-enabled/000-default.conf

Added this line after DocumentRoot /var/www/html

<Directory /var/www/html>
   AllowOverride All
</Directory>

Restart your apache server

Note: /var/www/html will be your document root

I'd solve it with a javascript solution (jQUery) if the sizes can vary.

window.setTimeout(function () {
    $(document).ready(function () {
        var ResizeTarget = $('#B');

        ResizeTarget.resize(function () {
            var target = $('#B2');
            target.css('height', ResizeTarget.height());
        }).trigger('resize');
    }); 
}, 500);

First, thanks for the answers above! They lead to my solution.

I added this alias to my .bashrc file:

alias now='date +%Y-%m-%d-%H.%M.%S'

Now when I want to put a time stamp on a file such as a build log I can do this:

mvn clean install | tee build-$(now).log

and I get a file name like:

build-2021-02-04-03.12.12.log

this $('#checkboxId').is(':checked') for verify if is checked

& this $("#checkboxId").prop('checked', true) to check

& this $("#checkboxId").prop('checked', false) to uncheck

I like Guffa's answer and since I can't comment I will provide the answer Udil's question here.

I needed something similar but I wanted certein logic in my token, I wanted to:

1. See the expiration of a token
2. Use a guid to mask validate (global application guid or user guid)
3. See if the token was provided for the purpose I created it (no reuse..)
4. See if the user I send the token to is the user that I am validating it for

Now points 1-3 are fixed length so it was easy, here is my code:

Here is my code to generate the token:

public string GenerateToken(string reason, MyUser user)
{
    byte[] _time     = BitConverter.GetBytes(DateTime.UtcNow.ToBinary());
    byte[] _key      = Guid.Parse(user.SecurityStamp).ToByteArray();
    byte[] _Id       = GetBytes(user.Id.ToString());
    byte[] _reason   = GetBytes(reason);
    byte[] data       = new byte[_time.Length + _key.Length + _reason.Length+_Id.Length];

    System.Buffer.BlockCopy(_time, 0, data, 0, _time.Length);
    System.Buffer.BlockCopy(_key , 0, data, _time.Length, _key.Length);
    System.Buffer.BlockCopy(_reason, 0, data, _time.Length + _key.Length, _reason.Length);
    System.Buffer.BlockCopy(_Id, 0, data, _time.Length + _key.Length + _reason.Length, _Id.Length);

    return Convert.ToBase64String(data.ToArray());
}

Here is my Code to take the generated token string and validate it:

public TokenValidation ValidateToken(string reason, MyUser user, string token)
{
    var result = new TokenValidation();
    byte[] data     = Convert.FromBase64String(token);
    byte[] _time     = data.Take(8).ToArray();
    byte[] _key      = data.Skip(8).Take(16).ToArray();
    byte[] _reason   = data.Skip(24).Take(2).ToArray();
    byte[] _Id       = data.Skip(26).ToArray();

    DateTime when = DateTime.FromBinary(BitConverter.ToInt64(_time, 0));
    if (when < DateTime.UtcNow.AddHours(-24))
    {
        result.Errors.Add( TokenValidationStatus.Expired);
    }
    
    Guid gKey = new Guid(_key);
    if (gKey.ToString() != user.SecurityStamp)
    {
        result.Errors.Add(TokenValidationStatus.WrongGuid);
    }

    if (reason != GetString(_reason))
    {
        result.Errors.Add(TokenValidationStatus.WrongPurpose);
    }

    if (user.Id.ToString() != GetString(_Id))
    {
        result.Errors.Add(TokenValidationStatus.WrongUser);
    }
    
    return result;
}

private static string GetString(byte[] reason) => Encoding.ASCII.GetString(reason);

private static byte[] GetBytes(string reason) => Encoding.ASCII.GetBytes(reason);

The TokenValidation class looks like this:

public class TokenValidation
{
    public bool Validated { get { return Errors.Count == 0; } }
    public readonly List<TokenValidationStatus> Errors = new List<TokenValidationStatus>();
}

public enum TokenValidationStatus
{
    Expired,
    WrongUser,
    WrongPurpose,
    WrongGuid
}

Now I have an easy way to validate a token, no Need to Keep it in a list for 24 hours or so. Here is my Good-Case Unit test:

private const string ResetPasswordTokenPurpose = "RP";
private const string ConfirmEmailTokenPurpose  = "EC";//change here change bit length for reason  section (2 per char)

[TestMethod]
public void GenerateTokenTest()
{
    MyUser user         = CreateTestUser("name");
    user.Id             = 123;
    user.SecurityStamp  = Guid.NewGuid().ToString();
    var token   = sit.GenerateToken(ConfirmEmailTokenPurpose, user);
    var validation    = sit.ValidateToken(ConfirmEmailTokenPurpose, user, token);
    Assert.IsTrue(validation.Validated,"Token validated for user 123");
}

One can adapt the code for other business cases easely.

Happy Coding

In Sender Activity Side:

Intent passIntent = new Intent(getApplicationContext(), "ActivityName".class);
passIntent.putExtra("value", integerValue);
startActivity(passIntent);

In Receiver Activity Side:

int receiveValue = getIntent().getIntExtra("value", 0);

Display:block It very much behaves the same way as 'p' tags and it takes up the entire row and there can't be any element next to it until it's floated. Display:inline It's just uses as much space as required and allows other elements to be aligned alongside itself.

Use these properties in case of forms and you will get a better understanding.

Perfect solution I have tried it and succeed to get my index page when I have append this code in my site configuration file.

location / {
            try_files $uri $uri/ /index.php;
}

In configuration file itself explained that at "First attempt to serve request as file, then as directory, then fall back to index.html in my case it is index.php as I am providing page through php code.

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

Pretty much what others have put before, but as a one liner that can be put at the beginning of a batch command. (Well, usually after @echo off.)

The answer is: for no good reason whatsoever.

Contrary to its name, the XmlSerializer class is used not only for serialization, but also for deserialization. It performs certain checks on your class to make sure that it will work, and some of those checks are only pertinent to deserialization, but it performs them all anyway, because it does not know what you intend to do later on.

The check that your class fails to pass is one of the checks that are only pertinent to deserialization. Here is what happens:

• During deserialization, the XmlSerializer class will need to create instances of your type.

• In order to create an instance of a type, a constructor of that type needs to be invoked.

• If you did not declare a constructor, the compiler has already supplied a default parameterless constructor, but if you did declare a constructor, then that's the only constructor available.

• So, if the constructor that you declared accepts parameters, then the only way to instantiate your class is by invoking that constructor which accepts parameters.

• However, XmlSerializer is not capable of invoking any constructor except a parameterless constructor, because it does not know what parameters to pass to constructors that accept parameters. So, it checks to see if your class has a parameterless constructor, and since it does not, it fails.

So, if the XmlSerializer class had been written in such a way as to only perform the checks pertinent to serialization, then your class would pass, because there is absolutely nothing about serialization that makes it necessary to have a parameterless constructor.

As others have already pointed out, the quick solution to your problem is to simply add a parameterless constructor. Unfortunately, it is also a dirty solution, because it means that you cannot have any readonly members initialized from constructor parameters.

In addition to all this, the XmlSerializer class could have been written in such a way as to allow even deserialization of classes without parameterless constructors. All it would take would be to make use of "The Factory Method Design Pattern" (Wikipedia). From the looks of it, Microsoft decided that this design pattern is far too advanced for DotNet programmers, who apparently should not be unnecessarily confused with such things. So, DotNet programmers should better stick to parameterless constructors, according to Microsoft.

Here is my simple binary search tree implementation in Java SE 1.8:

{
    int data;
    BSTNode parent;

    BSTNode right;

    public BSTNode(int data)
    {
        this.data = data;
        this.left = null;
        this.right = null;
        this.parent = null;
    }

    public BSTNode()
    {
    }
}

public class BSTFunctions
{
    BSTNode ROOT;

    public BSTFunctions()
    {
        this.ROOT = null;
    }

    void insertNode(BSTNode node, int data)
    {
        if (node == null)
        {
            node = new BSTNode(data);

This gets a view controller from the storyboard and presents it.

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let secondViewController = storyboard.instantiateViewController(withIdentifier: "secondViewControllerId") as! SecondViewController
self.present(secondViewController, animated: true, completion: nil)

Change the storyboard name, view controller name, and view controller id as appropriate.

I realize there are a ton of solutions here, but I found none of them hit every requirement I had:

• No custom coding required
• Code works on page load
• No custom classes required (checkboxes or their parent)
• I needed several checkbox lists to share the same name for submitting Github issues via their API, and was using the name label[] to assign labels across many form fields (two checkbox lists and a few selects and textboxes) - granted I could have achieved this without them sharing the same name, but I decided to try it, and it worked.

The only requirement for this one is jQuery. You can combine this with @ewall's great solution to add custom validation error messages.

I use $(date +"%Y-%m-%d") or $(date +"%Y-%m-%d %T") with time and hours.

You need to use the __getitem__ method.

class MyClass:
    def __getitem__(self, key):
        return key * 2

myobj = MyClass()
myobj[3] #Output: 6

And if you're going to be setting values you'll need to implement the __setitem__ method too, otherwise this will happen:

>>> myobj[5] = 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: MyClass instance has no attribute '__setitem__'

I had to add packaging, so:

mvn install:install-file \
  -DgroupId=javax.transaction \
  -DartifactId=jta \
  -Dversion=1.0.1B \
  -Dfile=jta-1.0.1B.jar \
  -DgeneratePom=true \
  -Dpackaging=jar

You can do it in one sql statement for existing customers, 3 statements for new ones. All you have to do is be an optimist and act as though the customer already exists:

insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);

If the customer does not exist, you'll get an sql exception which text will be something like:

null value in column "customer_id" violates not-null constraint

(providing you made customer_id non-nullable, which I'm sure you did). When that exception occurs, insert the customer into the customer table and redo the insert into the order table:

insert into customer(name) values ('John');
insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);

Unless your business is growing at a rate that will make "where to put all the money" your only real problem, most of your inserts will be for existing customers. So, most of the time, the exception won't occur and you'll be done in one statement.

Hopefully it helps someone: I ran into this error and the cause was wrong permission on the log folder for phpfpm, after changing it so phpfpm could write to it, everything was fine.

#include <string>

enum Errors {ErrorA=0, ErrorB, ErrorC};

std::ostream& operator<<(std::ostream& out, const Errors value){
    static std::map<Errors, std::string> strings;

    return out << strings[value];
}

int main(int argc, char** argv){
    std::cout << ErrorA << std::endl << ErrorB << std::endl << ErrorC << std::endl;
    return 0;

Using array of structures with linear search:

#include <iostream>

enum Errors {ErrorA=0, ErrorB, ErrorC};

std::ostream& operator<<(std::ostream& out, const Errors value){
#define MAPENTRY(p) {p, #p}
    const struct MapEntry{

        MAPENTRY(ErrorA),
        MAPENTRY(ErrorB),
        MAPENTRY(ErrorC),
        {ErrorA, 0}//doesn't matter what is used instead of ErrorA here...
    };
#undef MAPENTRY
    const char* s = 0;
    for (const MapEntry* i = entries; i->str; i++){
        if (i->value == value){
            s = i->str;
            break;

    }

    return out << s;
}

int main(int argc, char** argv){
    std::cout << ErrorA << std::endl << ErrorB << std::endl << ErrorC << std::endl;
    return 0;   
}

Using switch/case:

#include <iostream>
#include <string>

enum Errors {ErrorA=0, ErrorB, ErrorC};

std::ostream& operator<<(std::ostream& out, const Errors value){
    const char* s = 0;
#define PROCESS_VAL(p) case(p): s = #p; break;

int main(int argc, char** argv){
    std::cout << ErrorA << std::endl << ErrorB << std::endl << ErrorC << std::endl;
    return 0;   
}

If your script is called myScript.js and you want to pass the first and last name, 'Sean Worthington', as arguments like below:

node myScript.js Sean Worthington

Then within your script you write:

var firstName = process.argv[2]; // Will be set to 'Sean'
var lastName = process.argv[3]; // Will be set to 'Worthington'

There is some cases when you copy and paste the CSS code in somewhere and it breaks the format so Chrome show the yellow warning. You should try to reformat the CSS code again and it should be fine.

Try this:

$mpdf->Output('my_filename.pdf','D'); 

because:

D - means Download
F - means File-save only

The above works,(having an original document with mixed pages of 11' and 16' wide). However auto rotate needs to be off otherwise landscape pages are saved with page white top and bottom, so dont work in full screen view.

Solution is to re open the new PDF in acrobat and crop the first image (carefully to avoid white border), then select page range i.e. all, this then applies to all pages. job done !

One more solution REPLACE (CHAR(current date, ISO),'-','')

I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.

sudo apt-get install openjfx

Simply put the following one. This works for me.

$('.className').datepicker('setDate', 'now');

Instead of creating selector, Best way to create a style.

<style name="AppTheme.BottomBar">

and to change the text size, selected or non selected.

<dimen name="design_bottom_navigation_text_size" tools:override="true">11sp</dimen>
<dimen name="design_bottom_navigation_active_text_size" tools:override="true">12sp</dimen>

When generating CSR is possible to specify -ext attribute again to have it inserted in the CSR

keytool -certreq -file test.csr -keystore test.jks -alias testAlias -ext SAN=dns:test.example.com

complete example here: How to create CSR with SANs using keytool

data1.reset_index(inplace=True)

At the most basic level, something of the form (function(){...})() is a function literal that is executed immediately. What this means is that you have defined a function and you are calling it immediately.

This form is useful for information hiding and encapsulation since anything you define inside that function remains local to that function and inaccessible from the outside world (unless you specifically expose it - usually via a returned object literal).

A variation of this basic form is what you see in jQuery plugins (or in this module pattern in general). Hence:

(function($) {
  ...
})(jQuery);

Which means you're passing in a reference to the actual jQuery object, but it's known as $ within the scope of the function literal.

Type 1 isn't really a plugin. You're simply assigning an object literal to jQuery.fn. Typically you assign a function to jQuery.fn as plugins are usually just functions.

Type 2 is similar to Type 1; you aren't really creating a plugin here. You're simply adding an object literal to jQuery.fn.

Type 3 is a plugin, but it's not the best or easiest way to create one.

To understand more about this, take a look at this similar question and answer. Also, this page goes into some detail about authoring plugins.

SQL Server allows you to join tables from different databases as long as those databases are on the same server. The join syntax is the same; the only difference is that you must fully specify table names.

Let's suppose you have two databases on the same server - Db1 and Db2. Db1 has a table called Clients with a column ClientId and Db2 has a table called Messages with a column ClientId (let's leave asside why those tables are in different databases).

Now, to perform a join on the above-mentioned tables you will be using this query:

select *
from Db1.dbo.Clients c
join Db2.dbo.Messages m on c.ClientId = m.ClientId

For in-place sorting in descending order:

int[] numbers = { 1, 2, 3 };
Array.Sort(numbers, (a, b) => b.CompareTo(a));

For out-of-place sorting (no changes to input array):

int[] numbers = { 1, 2, 3 };
var sortedNumbers = numbers.OrderByDescending(x => x).ToArray();

Are you hosting the site on iis? if so make sure the account your website runs under has access to local file system?

Straight from msdn .....

The Network Service account has Read and Execute permissions on the IIS server root folder by default. The IIS server root folder is named Wwwroot. This means that an ASP.NET application deployed inside the root folder already has Read and Execute permissions to its application folders. However, if your ASP.NET application needs to use files or folders in other locations, you must specifically enable access.

To provide access to an ASP.NET application running as Network Service, you must grant access to the Network Service account.

To grant read, write, and modify permissions to a specific file

• In Windows Explorer, locate and select the required file.
• Right-click the file, and then click Properties.
• In the Properties dialog box, click the Security tab.
• On the Security tab, examine the list of users. If the Network Service
• account is not listed, add it.
• In the Properties dialog box, click the Network Service user name, and in the Permissions for NETWORK SERVICE section, select the Read, Write, and Modify permissions.
• Click Apply, and then click OK.

Maybe you need "sys." before:

select * from sys.registry$history;

Also, if you'd like to know global memory rather than node process':

var os = require('os');

os.freemem();
os.totalmem();

See documentation

The best approach to this problem is first making the database column UNIQUE

ALTER TABLE table_name ADD UNIQUE KEY

THEN INSERT IGNORE INTO table_name ,the value won't be inserted if it results in a duplicate key/already exists in the table.

Don't forget to update your iptables firewall if you have one to allow the 20-21 and 1024-1048 ranges in.

Do this from /etc/sysconfig/iptables

Adding lines like this:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 20:21 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 1024:1048 -j ACCEPT

And restart iptables with the command:

sudo service iptables restart

Combining Max's answer and Shriramana Sharma's mailing list post, I built a small working example for loading a mywindow.ui file containing a QMainWindow (so just choose to create a Main Window in Qt Designer's File-New dialog).

This is the code that loads it:

import sys
from PyQt4 import QtGui, uic

class MyWindow(QtGui.QMainWindow):
    def __init__(self):
        super(MyWindow, self).__init__()
        uic.loadUi('mywindow.ui', self)
        self.show()

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    window = MyWindow()
    sys.exit(app.exec_())

I just used the following:

import unicodedata
message = unicodedata.normalize("NFKD", message)

Check what documentation says about it:

unicodedata.normalize(form, unistr) Return the normal form form for the Unicode string unistr. Valid values for form are ‘NFC’, ‘NFKC’, ‘NFD’, and ‘NFKD’.

The Unicode standard defines various normalization forms of a Unicode string, based on the definition of canonical equivalence and compatibility equivalence. In Unicode, several characters can be expressed in various way. For example, the character U+00C7 (LATIN CAPITAL LETTER C WITH CEDILLA) can also be expressed as the sequence U+0043 (LATIN CAPITAL LETTER C) U+0327 (COMBINING CEDILLA).

For each character, there are two normal forms: normal form C and normal form D. Normal form D (NFD) is also known as canonical decomposition, and translates each character into its decomposed form. Normal form C (NFC) first applies a canonical decomposition, then composes pre-combined characters again.

In addition to these two forms, there are two additional normal forms based on compatibility equivalence. In Unicode, certain characters are supported which normally would be unified with other characters. For example, U+2160 (ROMAN NUMERAL ONE) is really the same thing as U+0049 (LATIN CAPITAL LETTER I). However, it is supported in Unicode for compatibility with existing character sets (e.g. gb2312).

The normal form KD (NFKD) will apply the compatibility decomposition, i.e. replace all compatibility characters with their equivalents. The normal form KC (NFKC) first applies the compatibility decomposition, followed by the canonical composition.

Even if two unicode strings are normalized and look the same to a human reader, if one has combining characters and the other doesn’t, they may not compare equal.

Solves it for me. Simple and easy.

Or you can style it with pixels.

 .big-checkbox {width: 30px; height: 30px;}

if you have the file inside a dirrectory called uploads in your project. bellow code can be used.

Path root = Paths.get("uploads");
File existingFile = new File(this.root.resolve("img.png").toUri());

if (existingFile.exists() && existingFile.isFile()) {
     existingFile.delete();
   }

OR

If it is inside a different directory this solution can be used.

File existingFile = new File("D:\\<path>\\img.png");

if (existingFile.exists() && existingFile.isFile()) {
    existingFile.delete();
  }

I found another server side solution for web dev using PHP to get the size of an iframe.

First is using server script PHP to an external call via internal function: (like a file_get_contents with but curl and dom).

function curl_get_file_contents($url,$proxyActivation=false) {
    global $proxy;
    $c = curl_init();
    curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
    curl_setopt($c, CURLOPT_REFERER, $url);
    curl_setopt($c, CURLOPT_URL, $url);
    curl_setopt($c, CURLOPT_FOLLOWLOCATION, 1);
    if($proxyActivation) {
        curl_setopt($c, CURLOPT_PROXY, $proxy);
    }
    $contents = curl_exec($c);
    curl_close($c);
    $dom = new DOMDocument();
    $dom->preserveWhiteSpace = false;
    @$dom->loadHTML($contents);
    $form = $dom->getElementsByTagName("body")->item(0);
    if ($contents) //si on a du contenu
        return $dom->saveHTML();
    else
        return FALSE;
}
$url = "http://www.google.com"; //Exernal url test to iframe
<html>
    <head>
    <script type="text/javascript">

    </script>
    <style type="text/css">
    #iframe_reserve {
        width: 560px;
        height: 228px
    }
    </style>
    </head>

    <body>
        <div id="iframe_reserve"><?php echo curl_get_file_contents($url); ?></div>

        <iframe id="myiframe" src="http://www.google.com" scrolling="no" marginwidth="0" marginheight="0" frameborder="0"  style="overflow:none; width:100%; display:none"></iframe>

        <script type="text/javascript">
            window.onload = function(){
            document.getElementById("iframe_reserve").style.display = "block";
            var divHeight = document.getElementById("iframe_reserve").clientHeight;
            document.getElementById("iframe_reserve").style.display = "none";
            document.getElementById("myiframe").style.display = "block";
            document.getElementById("myiframe").style.height = divHeight;
            alert(divHeight);
            };
        </script>
    </body>
</html>

You need to display under the div (iframe_reserve) the html generated by the function call by using a simple echo curl_get_file_contents("location url iframe","activation proxy")

After doing this a body event function onload with javascript take height of the page iframe just with a simple control of the content div (iframe_reserve)

So I used divHeight = document.getElementById("iframe_reserve").clientHeight; to get height of the page external we are going to call after masked the div container (iframe_reserve). After this we load the iframe with its good height that's all.

Important step for Event binding on Ajax loading content...

01. First of all unbind or off the event on selector

$(".SELECTOR").off();

02. Add event listener on document level

$(document).on("EVENT", '.SELECTOR', function(event) { 
    console.log("Selector event occurred");
});

You'll need to use fs for that: http://nodejs.org/api/fs.html

And in particular the fs.rename() function:

var fs = require('fs');
fs.rename('/path/to/Afghanistan.png', '/path/to/AF.png', function(err) {
    if ( err ) console.log('ERROR: ' + err);
});

Put that in a loop over your freshly-read JSON object's keys and values, and you've got a batch renaming script.

fs.readFile('/path/to/countries.json', function(error, data) {
    if (error) {
        console.log(error);
        return;
    }

    var obj = JSON.parse(data);
    for(var p in obj) {
        fs.rename('/path/to/' + obj[p] + '.png', '/path/to/' + p + '.png', function(err) {
            if ( err ) console.log('ERROR: ' + err);
        });
    }
});

(This assumes here that your .json file is trustworthy and that it's safe to use its keys and values directly in filenames. If that's not the case, be sure to escape those properly!)

The best methods are already given but why not look at a couple of other methods for fun? Warning: these are more expensive methods but do serve in other circumstances.

The expensive regex method and the css attribute selector with starts with ^ operator

Option Explicit

Public Sub test()

    Debug.Print StartWithSubString("ab", "abc,d")

End Sub

Regex:

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft VBScript Regular Expressions
    Dim re As VBScript_RegExp_55.RegExp
    Set re = New VBScript_RegExp_55.RegExp

    re.Pattern = "^" & substring

    StartWithSubString = re.test(testString)

End Function

Css attribute selector with starts with operator

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft HTML Object Library
    Dim html As MSHTML.HTMLDocument
    Set html = New MSHTML.HTMLDocument

    html.body.innerHTML = "<div test=""" & testString & """></div>"

    StartWithSubString = html.querySelectorAll("[test^=" & substring & "]").Length > 0

End Function

VC++ is not actually a language but is commonly referred to like one. When VC++ is referred to as a language, it usually means Microsoft's implementation of C++, which contains various knacks that do not exist in regular C++, such as the __super keyword. It is similar to the various GNU extensions to the C language that are implemented in GCC.

You can paste the .jar file of the driver in the Java setup instead of adding it to each project that you create. Paste it in C:\Program Files\Java\jre7\lib\ext or wherever you have installed java.

After this you will find that the .jar driver is enlisted in the library folder of your created project(JRE system library) in the IDE. No need to add it repetitively.

I believe there are means to make homebrew python default, but in my opinion the proper way to solve a problem is not to mess with system python paths: it is better to create a virtualenv in which homebrew python would be default (by using virtualenv --python option). Using tools like python_select is almost always a bad idea.

Here and easy Example.

As for me here the most easily way to add text(Tab -> \t) in textarea by cursor position and save the focus on cursor:

$('#text').keyup(function () {
    var cursor = $('#text').prop('selectionStart');
    //if cursot is first in textarea
    if (cursor == 0) {
        //i will add tab in line
        $('#text').val('\t' + $('#text').val());
        //here we set the cursor position
        $('#text').prop('selectionEnd', 1);
    } else {
        var value = $('#text').val();
        //save the value before cursor current position
        var valToCur = value.substring(0, cursor);
        //save the value after cursor current position
        var valAfter = value.substring(cursor, value.length);
        //save the new value with added tab in text
        $('#text').val(valToCur + '\t' + valAfter);
        //set focus of cursot after insert text (1 = because I add only one symbol)
        $('#text').prop('selectionEnd', cursor + 1);
    }
});

I use year 2000 instead of Epoch Time in my calculus. Working with smaller numbers is easy to store and transport and is JSON friendly.

Year 2000 was at second 946684800 of epoch time.

Year 2000 was at second 63082281600 from 1-st of Jan 0001.

DateTime.UtcNow Ticks starts from 1-st of Jan 0001

Seconds from year 2000:

DateTime.UtcNow.Ticks/10000000-63082281600

Seconds from Unix Time:

DateTime.UtcNow.Ticks/10000000-946684800

For example year 2020 is:

var year2020 = (new DateTime()).AddYears(2019).Ticks; // Because DateTime starts already at year 1

637134336000000000 Ticks since 1-st of Jan 0001

63713433600 Seconds since 1-st of Jan 0001

1577836800 Seconds since Epoch Time

631152000 Seconds since year 2000

try to upgrade each of those modules using pecl command

# pecl upgrade fileinfo
# pecl upgrade memcache
# pecl upgrade mhash
# pecl upgrade readline

etc...

How about the below solution? It worked for me. Try this:

.modal .modal-body {
    max-height: 420px;
    overflow-y: auto;
}

Details:

1. remove overflow-y: auto; or overflow: auto; from .modal class (important)
2. remove max-height: 400px; from .modal class (important)
3. Add max-height: 400px; to .modal .modal-body (or what ever, can be 420px or less, but would not go more than 450px)
4. Add overflow-y: auto; to .modal .modal-body

Done, only body will scroll.

The quintessential example of this is an array of pointers to structs or objects (that are mutable).

A shallow copy copies the array and maintains references to the original objects.

A deep copy will copy (clone) the objects too so they bear no relation to the original. Implicit in this is that the object themselves are deep copied. This is where it gets hard because there's no real way to know if something was deep copied or not.

The copy constructor is used to initilize the new object with the previously created object of the same class. By default compiler wrote a shallow copy. Shallow copy works fine when dynamic memory allocation is not involved because when dynamic memory allocation is involved then both objects will points towards the same memory location in a heap, Therefore to remove this problem we wrote deep copy so both objects have their own copy of attributes in a memory.

In order to read the details with complete examples and explanations you could see the article Constructors and destructors.

The default copy constructor is shallow. You can make your own copy constructors deep or shallow, as appropriate. See C++ Notes: OOP: Copy Constructors.

If using Visual Studio 2019, just delete the "defaultproxy" section if you are not using any default proxies in devenv.exe.config. in VS 2017 this section was not present

change

<defaultProxy enabled="true" useDefaultCredentials="true">
    <proxy bypassonlocal="True" proxyaddress="http://<yourproxy:port#>"/>
</defaultProxy>

to

<!--<defaultProxy enabled="true" useDefaultCredentials="true">
    <proxy bypassonlocal="True" proxyaddress="http://<yourproxy:port#>"/>
</defaultProxy>-->

Else provide the appropriate proxy username and password.

hg status will show you all the new files, and then you can just rm them.

Normally I want to get rid of ignored and unversioned files, so:

hg status -iu                          # to show 
hg status -iun0 | xargs -r0 rm         # to destroy

And then follow that with:

hg update -C -r xxxxx

which puts all the versioned files in the right state for revision xxxx

To follow the Stack Overflow tradition of telling you that you don't want to do this, I often find that this "Nuclear Option" has destroyed stuff I care about.

The right way to do it is to have a 'make clean' option in your build process, and maybe a 'make reallyclean' and 'make distclean' too.

header('Location: '.$_SERVER['REQUEST_URI']);

Try to use it this way:

let current_time = moment().format("HH:mm")

i guess you mean System Programs and Application programs

System Programs makes the hardware run , Applications are for specific tasks

an Example for System Programs are Device Drivers

as for the Applications you can say web browsers , word porcessros etc

generalising to multiple columns, why not:

columns = ['whatever', 'columns', 'you', 'choose']
df['period'] = df[columns].astype(str).sum(axis=1)

try this

<html>
<head>
<script type="text/javascript">
function openWin()
{
myWindow=window.open('','','width=200,height=100');
myWindow.document.write("<p>This is 'myWindow'</p>");
myWindow.focus();
print(myWindow);
}
</script>
</head>
<body>

<input type="button" value="Open window" onclick="openWin()" />

</body>
</html>

If you simply want to create an empty data frame and fill it with some incoming data frames later, try this:

newDF = pd.DataFrame() #creates a new dataframe that's empty
newDF = newDF.append(oldDF, ignore_index = True) # ignoring index is optional
# try printing some data from newDF
print newDF.head() #again optional 

In this example I am using this pandas doc to create a new data frame and then using append to write to the newDF with data from oldDF.

If I have to keep appending new data into this newDF from more than one oldDFs, I just use a for loop to iterate over pandas.DataFrame.append()

To see of the curent time is greater or equal to 14:08:10 do this:

if (time() >= strtotime("14:08:10")) {
  echo "ok";
}

Depending on your input sources, make sure to account for timezone.

See PHP time() and PHP strtotime()

After upgrading react-native, you may have stale dependencies. The steps below should fix it.

1. cd ios
2. delete Podfile.lock
3. pod deintegrate && pod install
4. Navigate back to package.json directory
5. run react-native run-ios
6. In Xcode you can build your project again too

Hope this helps, I did this after upgrading to react-native 0.61

Solution:

Use the Search all shortcut: Ctrl+Shift+F, then select the folder in the "Where:" box below. (And for Mac, it's ?+Shift+F).

If the root directory for the project is proj, with subdirectories src and aux and you want to search in all subfolders, use the proj folder. To restrict the search to only the src folder, use proj/src in the "Where: " box.

To my knowledge the use of the keyword new, does relatively the same thing as malloc(sizeof identifier). The code below demonstrates how to use the keyword new.

    void main(void){
        int* test;
        test = tester();
        printf("%d",*test);
        system("pause");
    return;
}
    int* tester(void){
        int *retMe;
        retMe = new int;//<----Here retMe is getting malloc for integer type
        *retMe = 12;<---- Initializes retMe... Note * dereferences retMe 
    return retMe;
}

When using Python 2.4, try

inf = float("9e999")
nan = inf - inf

I am facing the issue when I was porting the simplejson to an embedded device which running the Python 2.4, float("9e999") fixed it. Don't use inf = 9e999, you need convert it from string. -inf gives the -Infinity.

Go to python console by typing

$ python

in your terminal. Then, type the following 2 commands in your python shell to install the respective packages:

>> nltk.download('punkt') >> nltk.download('averaged_perceptron_tagger')

This solved the issue for me.

SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;

Just make sure that in the SELECT line you specify which table columns you are using, either by full reference, or by alias. Any of the following will work:

SELECT *
SELECT t1.*,t2.column2
SELECT A.table1.column1, t2.*
etc.

If you are willing to make use of C++11 std::async and std::future for running your tasks, then you can utilize the wait_for function of std::future to check if the thread is still running in a neat way like this:

#include <future>
#include <thread>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    /* Run some task on new thread. The launch policy std::launch::async
       makes sure that the task is run asynchronously on a new thread. */
    auto future = std::async(std::launch::async, [] {
        std::this_thread::sleep_for(3s);
        return 8;
    });

    // Use wait_for() with zero milliseconds to check thread status.
    auto status = future.wait_for(0ms);

    // Print status.
    if (status == std::future_status::ready) {
        std::cout << "Thread finished" << std::endl;
    } else {
        std::cout << "Thread still running" << std::endl;
    }

    auto result = future.get(); // Get result.
}

If you must use std::thread then you can use std::promise to get a future object:

#include <future>
#include <thread>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    // Create a promise and get its future.
    std::promise<bool> p;
    auto future = p.get_future();

    // Run some task on a new thread.
    std::thread t([&p] {
        std::this_thread::sleep_for(3s);
        p.set_value(true); // Is done atomically.
    });

    // Get thread status using wait_for as before.
    auto status = future.wait_for(0ms);

    // Print status.
    if (status == std::future_status::ready) {
        std::cout << "Thread finished" << std::endl;
    } else {
        std::cout << "Thread still running" << std::endl;
    }

    t.join(); // Join thread.
}

Both of these examples will output:

Thread still running

This is of course because the thread status is checked before the task is finished.

But then again, it might be simpler to just do it like others have already mentioned:

#include <thread>
#include <atomic>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    std::atomic<bool> done(false); // Use an atomic flag.

    /* Run some task on a new thread.
       Make sure to set the done flag to true when finished. */
    std::thread t([&done] {
        std::this_thread::sleep_for(3s);
        done = true;
    });

    // Print status.
    if (done) {
        std::cout << "Thread finished" << std::endl;
    } else {
        std::cout << "Thread still running" << std::endl;
    }

    t.join(); // Join thread.
}

Edit:

There's also the std::packaged_task for use with std::thread for a cleaner solution than using std::promise:

#include <future>
#include <thread>
#include <chrono>
#include <iostream>

int main() {
    using namespace std::chrono_literals;

    // Create a packaged_task using some task and get its future.
    std::packaged_task<void()> task([] {
        std::this_thread::sleep_for(3s);
    });
    auto future = task.get_future();

    // Run task on new thread.
    std::thread t(std::move(task));

    // Get thread status using wait_for as before.
    auto status = future.wait_for(0ms);

    // Print status.
    if (status == std::future_status::ready) {
        // ...
    }

    t.join(); // Join thread.
}

I create the dialog using AlertDialog.Builder so I used Rodrigo's answer inside a OnShowListener.

dialog.setOnShowListener(new OnShowListener() {

            @Override
            public void onShow(DialogInterface dialogInterface) {
                Display display = getWindowManager().getDefaultDisplay();
                DisplayMetrics outMetrics = new DisplayMetrics ();
                display.getMetrics(outMetrics);
                dialog.getWindow().setLayout((int)(312 * outMetrics.density), (int)(436 * outMetrics.density));
            }

        });

To expand on some of the previous answers, I found that Oracle DATE objects behave different from Oracle TIMESTAMP objects. In particular, if you set your NLS_DATE_FORMAT to include fractional seconds, the entire time portion is omitted.

• Format "YYYY-MM-DD HH24:MI:SS" works as expected, for DATE and TIMESTAMP
• Format "YYYY-MM-DD HH24:MI:SSXFF" displays just the date portion for DATE, works as expected for TIMESTAMP

My personal preference is to set DATE to "YYYY-MM-DD HH24:MI:SS", and to set TIMESTAMP to "YYYY-MM-DD HH24:MI:SSXFF".

This is used in several apps to clean user-generated content removing extra spacing/returns etc but retains the meaning of spaces.

text.replace(/[\n\r\s\t]+/g, ' ')

Catching an exception while using a Python 'with' statement

The with statement has been available without the __future__ import since Python 2.6. You can get it as early as Python 2.5 (but at this point it's time to upgrade!) with:

from __future__ import with_statement

Here's the closest thing to correct that you have. You're almost there, but with doesn't have an except clause:

with open("a.txt") as f: 
    print(f.readlines())
except:                    # <- with doesn't have an except clause.
    print('oops')

A context manager's __exit__ method, if it returns False will reraise the error when it finishes. If it returns True, it will suppress it. The open builtin's __exit__ doesn't return True, so you just need to nest it in a try, except block:

try:
    with open("a.txt") as f:
        print(f.readlines())
except Exception as error: 
    print('oops')

And standard boilerplate: don't use a bare except: which catches BaseException and every other possible exception and warning. Be at least as specific as Exception, and for this error, perhaps catch IOError. Only catch errors you're prepared to handle.

So in this case, you'd do:

>>> try:
...     with open("a.txt") as f:
...         print(f.readlines())
... except IOError as error: 
...     print('oops')
... 
oops

Here a solution that will work with Solaris and AIX as well.

Manipulating the Timezone is possible for changing the clock some hours. Due to the daylight saving time, 24 hours ago can be today or the day before yesterday.

You are sure that yesterday is 20 or 30 hours ago. Which one? Well, the most recent one that is not today.

echo -e "$(TZ=GMT+30 date +%Y-%m-%d)\n$(TZ=GMT+20 date +%Y-%m-%d)" | grep -v $(date +%Y-%m-%d) | tail -1

The -e parameter used in the echo command is needed with bash, but will not work with ksh. In ksh you can use the same command without the -e flag.

When your script will be used in different environments, you can start the script with #!/bin/ksh or #!/bin/bash. You could also replace the \n by a newline:

echo "$(TZ=GMT+30 date +%Y-%m-%d)
$(TZ=GMT+20 date +%Y-%m-%d)" | grep -v $(date +%Y-%m-%d) | tail -1

Even if you do start the executable outside Visual Studio, you can still use the "Attach" command to connect Visual Studio to your already-running executable. This can be useful e.g. when your application is run as a plug-in within another application.

Use Not IsNull(Fields!W_O_Count.Value)

A summary.lm object stores these values in a matrix called 'coefficients'. So the value you are after can be accessed with:

a2Pval <- summary(mg)$coefficients[2, 4]

Or, more generally/readably, coef(summary(mg))["a2","Pr(>|t|)"]. See here for why this method is preferred.

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

   ln -vs "$(find /Applications/Atom.app -name ctags-config -print -quit)" ~/.ctags
   

2. Go to your project folder and run:

   cd your/project/directory
   ctags -R .
   

3. Restart Atom editor.

Alternatively you can use symbol-gen package to generate ctags symbols file for your project based on the options found in .ctags file. You can install it from Atom Package Manager by: apm install symbol-gen. Then hit CMD-Alt-G to generate tags file for your project.

After following above, you can use Go To Declaration option from the context menu.

On macOS you can use also use the following keyboard shortcuts:

• CMD-R to jump to a function/method in the current ,editor
• Alt-CMD-Down to go to declaration.

Rookie, if you want to write a file to server by socket, how about using fileoutputstream instead of dataoutputstream? dataoutputstream is more fit for protocol-level read-write. it is not very reasonable for your code in bytes reading and writing. loop to read and write is necessary in java io. and also, you use a buffer way. flush is necessary. here is a code sample: http://www.rgagnon.com/javadetails/java-0542.html

There is an optional overload for DataBinder.Eval to supply formatting:

<%# DataBinder.Eval(Container.DataItem, "expression"[, "format"]) %>

The format parameter is a String value, using the value placeholder replacement syntax (called composite formatting) like this:

<asp:Label id="lblNewsDate" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "publishedDate", "{0:dddd d MMMM}") %>'</label>

A war is a webapp. If you want to have a console/standalone application reusing the same classes as you webapp, consider packaging your shared classes in a jar, which you can put in WEB-INF/lib. Then use that jar from the command line. Thus you get both your console application, and you can use the same classes in your servlets, without making two different packages. This, of course, is true when the war is exploded.

You may have to perform a diff and put document.getElementById('name') code inside a condition, in case your component is something like this:

// using the new hooks API
function Comp(props) {
  const { isLoading, data } = props;
  useEffect(() => {
    if (data) {
      var name = document.getElementById('name').value;
    }
  }, [data]) // this diff is necessary

  if (isLoading) return <div>isLoading</div>
  return (
    <div id='name'>Comp</div>
  );
}

If diff is not performed then, you will get null.

No, because it contains items there must be an instance of it. Its items being null is irrelevant, so the statment ((arrayList) != null) == true

According to Transport Layer Security (TLS) best practices with the .NET Framework: To ensure .NET Framework applications remain secure, the TLS version should not be hardcoded. Instead set the registry keys: SystemDefaultTlsVersions and SchUseStrongCrypto:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v2.0.50727]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727]

You can update gem to any specific version like this,

gem update --system 'version'

gem update --system '2.3.0'

BR generates a line-break and it is only a line-break. As this element has no content, there are only few styles that make sense to apply on it, like clear or position. You can set BR's border but you won't see it as it has no visual dimension.

If you like to visually separate two sentences, then you probably want to use the horizontal ruler which is intended for this goal. Since you cannot change the markup, I'm afraid using only CSS you cannot achieve this.

It seems, it has been already discussed on other forums. Extract from Re: Setting the height of a BR element using CSS:

[T]his leads to a somewhat odd status for BR in that on the one hand it is not being treated as a normal element, but instead as an instance of \A in generated content, but on the other hand it is being treated as a normal element in that (a limited subset of) CSS properties are being allowed on it.

I also found a clarification in the CSS 1 specification (no higher level spec mentions it):

The current CSS1 properties and values cannot describe the behavior of the ‘BR’ element. In HTML, the ‘BR’ element specifies a line break between words. In effect, the element is replaced by a line break. Future versions of CSS may handle added and replaced content, but CSS1-based formatters must treat ‘BR’ specially.

Grant Wagner's tests show that there is no way to style BR as you can do with other elements. There is also a site online where you can test the results in your browser.

Update

pelms made some further investigations, and pointed out that IE8 (on Win7) and Chrome 2/Safari 4b allows you to style BR somewhat. And indeed, I checked the IE demo page with IE Net Renderer's IE8 engine, and it worked.

Update 2 c69 made some further investigations, and it turns out you can style the marker for br quite heavily (though, not cross-browser), yet this will not affect the line-break itself, because it seem to belong to parent container.

>>> s = 'my string with \\"double quotes\\" blablabla'
>>> s
'my string with \\"double quotes\\" blablabla'
>>> print s
my string with \"double quotes\" blablabla
>>> 

When you just ask for 's' it escapes the \ for you, when you print it, you see the string a more 'raw' state. So now...

>>> s = """my string with "double quotes" blablabla"""
'my string with "double quotes" blablabla'
>>> print s.replace('"', '\\"')
my string with \"double quotes\" blablabla
>>> 

This does the trick:

CC        := g++
LD        := g++

MODULES   := widgets test ui
SRC_DIR   := $(addprefix src/,$(MODULES))
BUILD_DIR := $(addprefix build/,$(MODULES))

SRC       := $(foreach sdir,$(SRC_DIR),$(wildcard $(sdir)/*.cpp))
OBJ       := $(patsubst src/%.cpp,build/%.o,$(SRC))
INCLUDES  := $(addprefix -I,$(SRC_DIR))

vpath %.cpp $(SRC_DIR)

define make-goal
$1/%.o: %.cpp
    $(CC) $(INCLUDES) -c $$< -o $$@
endef

.PHONY: all checkdirs clean

all: checkdirs build/test.exe

build/test.exe: $(OBJ)
    $(LD) $^ -o $@


checkdirs: $(BUILD_DIR)

$(BUILD_DIR):
    @mkdir -p $@

clean:
    @rm -rf $(BUILD_DIR)

$(foreach bdir,$(BUILD_DIR),$(eval $(call make-goal,$(bdir))))

This Makefile assumes you have your include files in the source directories. Also it checks if the build directories exist, and creates them if they do not exist.

The last line is the most important. It creates the implicit rules for each build using the function make-goal, and it is not necessary write them one by one

You can also add automatic dependency generation, using Tromey's way

You have to put:

<html ng-app="urlApp" ng-controller="urlCtrl">

This way the angular function can access into "window" object

this : is the DOM Element $(this) : Jquery objct, which wrapped with Dom Element, you can check this answer also this vs $(this)

try like this Attr(). Get the value of an attribute for the first element in the set of matched elements.

$(document).ready(function () {
    $(".inputs").click(function () {
         alert(" or " + $(this).attr("id"));

    });
});

Similar to zproxy's answer above I have used the folowing code in the Gloabal.asax.cs to achieve this:

public class Global : System.Web.HttpApplication
{
    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        if (Request.Url.AbsolutePath.EndsWith("/"))
        {
            Server.Transfer(Request.Url.AbsolutePath + "index.aspx");
        }
    }
}

Angular CLI: 8.3.1

when you have multiple module.ts files inside a module, you need to specify for which module file you are generating component.

ng g c modulefolder/componentname --module=modulename.module

for e.g. i have shared module folder inside which i have shared.module.ts and material.module.ts like this

shared
  > shared.module.ts
  > material.module.ts

and i want to generate sidebar component for shared.module.ts then i will run following command

ng g c shared/sidebar --module=shared.module

if you want to export the component then run following command

ng g c shared/sidebar --module=shared.module --export

Lets try to understand in a different way.

What may happen if Abstraction is not there and What may happen if Encapsulation is not there.

If Abstraction is not there, then you can say the object is use less. You cannot identify the object nor can you access any functionality of it. Take a example of a TV, if you do not have an option to power on, change channel, increase or decrease volume etc., then what's the use of TV and how do you use it ?

If Encapsulation is not there or not being implemented properly, then you may misuse the object. There by data/components may get misused. Take the same example of TV, If there is no encapsulation done to the volume of TV, then the volume controller may be misused by making it come below or go beyond its limit (0-40/50).

As of Django 1.9, the simplest solution I have found (based on Quentin Stafford-Fraser's solution) is to add a few lines to manage.py which dynamically modify the default port number before invoking the runserver command:

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.dev")

    import django
    django.setup()

    # Override default port for `runserver` command
    from django.core.management.commands.runserver import Command as runserver
    runserver.default_port = "8080"

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

You should use static String.Compare function like following

x => String.Compare (x.Username, (string)drUser["Username"],
                     StringComparison.OrdinalIgnoreCase) == 0

Alternatively one can use the setExtremes method also,

yAxis.setExtremes(0, 100);

Or if only one value is needed to be set, just leave other as null

yAxis.setExtremes(null, 100);

You can use a HashingStrategy based Map from Eclipse Collections

HashingStrategy<String> hashingStrategy =
    HashingStrategies.fromFunction(String::toUpperCase);
MutableMap<String, String> node = HashingStrategyMaps.mutable.of(hashingStrategy);

Note: I am a contributor to Eclipse Collections.

In case of Swift User

// case of normal image
let image1 = UIImage(named: "your_image_file_name_without_extension")!
button1.setImage(image1, forState: UIControlState.Normal) 

// in case you don't want image to change when "clicked", you can leave code below
// case of when button is clicked
let image2 = UIImage(named: "image_clicked")!
button1.setImage(image2, forState: UIControlState.Highlight) 

function createDateRangeArray($start, $end) {
// Modified by JJ Geewax

$range = array();

if (is_string($start) === true) $start = strtotime($start);
if (is_string($end) === true ) $end = strtotime($end);

if ($start > $end) return createDateRangeArray($end, $start);

do {
$range[] = date('Y-m-d', $start);
$start = strtotime("+ 1 day", $start);
}
while($start < $end);

return $range;
}

If you don't have ISAPI and CGI Restrictions option listed, here is how to add it. How to add ISAPI and CGI Restrictions

Following is another way of doing it using plain PHP without the information_schema database:

$chkcol = mysql_query("SELECT * FROM `my_table_name` LIMIT 1");
$mycol = mysql_fetch_array($chkcol);
if(!isset($mycol['my_new_column']))
  mysql_query("ALTER TABLE `my_table_name` ADD `my_new_column` BOOL NOT NULL DEFAULT '0'");

I used ng-click directive to call a function, while requesting route templateUrl, to decide which <div> has to be show or hide inside route templateUrl page or for different scenarios.

AngularJS 1.6.9

Lets see an example, when in routing page, I need either the add <div> or the edit <div>, which I control using the parent controller models $scope.addProduct and $scope.editProduct boolean.

Answer is adding this 2 lines of code to Global.asax.cs Application_Start method

var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = 
    Newtonsoft.Json.PreserveReferencesHandling.All;

Reference: Handling Circular Object References

To get that file use the below code.

include(Mage::getBaseDir('skin').'myfunc.php');

But it is not a correct way. To add your custom functions you can use the below file.

app/code/core/Mage/core/functions.php

Kindly avoid to use the PHP function under skin dir.

SELECT date_created
FROM your_table
WHERE DATENAME(dw, date_created) NOT IN ('Saturday', 'Sunday')

Via css. Put this inside the <head> tag.

<style type="text/css" media="screen">

table{
border-collapse:collapse;
border:1px solid #FF0000;
}

table td{
border:1px solid #FF0000;
}
</style>

Check out parse_url():

$url = 'http://google.com/dhasjkdas/sadsdds/sdda/sdads.html';
$parse = parse_url($url);
echo $parse['host']; // prints 'google.com'

parse_url doesn't handle really badly mangled urls very well, but is fine if you generally expect decent urls.

In-place:

    public static void DistinctValues<T>(List<T> list)
    {
        list.Sort();

        int src = 0;
        int dst = 0;
        while (src < list.Count)
        {
            var val = list[src];
            list[dst] = val;

            ++dst;
            while (++src < list.Count && list[src].Equals(val)) ;
        }
        if (dst < list.Count)
        {
            list.RemoveRange(dst, list.Count - dst);
        }
    }

The answer from @gunn is correct, target="_blank makes the link open in a new tab.

But this can be a security risk for you page; you can read about it here. There is a simple solution for that: adding rel="noopener noreferrer".

<a style={{display: "table-cell"}} href = "someLink" target = "_blank" 
rel = "noopener noreferrer">text</a>

Follow the screenshot below. It works when you run the simulator (won't see it on preview)

I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between

   BEGIN
   SELECT MONTH(CURDATE()) INTO @curmonth;
   SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
   SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
   SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
   SELECT DAY(@checkweekday) INTO @checkday;
   SET @daycount = 0;
   SET @workdays = 0;

     WHILE(@daycount < @totaldays) DO
       IF (WEEKDAY(@checkweekday) < 5) THEN
         SET @workdays = @workdays+1;
       END IF;
       SET @daycount = @daycount+1;
       SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
     END WHILE;
   END

Just for others:

If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query

    delimiter ;;
    drop procedure if exists test2;;
    create procedure test2()
    begin
    select ‘Hello World’;
    end
    ;;

Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.

The first_day function you need is: How to get first day of every corresponding month in mysql?

Showing the Procedure is working Simply add the following line below END WHILE and above END

    SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;

Then use the following code in the SQL Query Window.

    call test2 /* or whatever you changed the name of the stored procedure to */

NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).

You need it to install development iPhone applications on development devices.

The easiest way to do this is to click on the Terminate button(red square) in the console:

someone here may find it useful. hhb_curl_exec2 works pretty much like curl_exec, but arg3 is an array which will be populated with the returned http headers (numeric index), and arg4 is an array which will be populated with the returned cookies ($cookies["expires"]=>"Fri, 06-May-2016 05:58:51 GMT"), and arg5 will be populated with... info about the raw request made by curl.

the downside is that it requires CURLOPT_RETURNTRANSFER to be on, else it error out, and that it will overwrite CURLOPT_STDERR and CURLOPT_VERBOSE, if you were already using them for something else.. (i might fix this later)

example of how to use it:

<?php
header("content-type: text/plain;charset=utf8");
$ch=curl_init();
$headers=array();
$cookies=array();
$debuginfo="";
$body="";
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$body=hhb_curl_exec2($ch,'https://www.youtube.com/',$headers,$cookies,$debuginfo);
var_dump('$cookies:',$cookies,'$headers:',$headers,'$debuginfo:',$debuginfo,'$body:',$body);

and the function itself..

function hhb_curl_exec2($ch, $url, &$returnHeaders = array(), &$returnCookies = array(), &$verboseDebugInfo = "")
{
    $returnHeaders    = array();
    $returnCookies    = array();
    $verboseDebugInfo = "";
    if (!is_resource($ch) || get_resource_type($ch) !== 'curl') {
        throw new InvalidArgumentException('$ch must be a curl handle!');
    }
    if (!is_string($url)) {
        throw new InvalidArgumentException('$url must be a string!');
    }
    $verbosefileh = tmpfile();
    $verbosefile  = stream_get_meta_data($verbosefileh);
    $verbosefile  = $verbosefile['uri'];
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_STDERR, $verbosefileh);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    $html             = hhb_curl_exec($ch, $url);
    $verboseDebugInfo = file_get_contents($verbosefile);
    curl_setopt($ch, CURLOPT_STDERR, NULL);
    fclose($verbosefileh);
    unset($verbosefile, $verbosefileh);
    $headers       = array();
    $crlf          = "\x0d\x0a";
    $thepos        = strpos($html, $crlf . $crlf, 0);

You can overwrite the classes in your own css using !important, e.g. if you want to get rid of the rounded corners.

.ui-corner-all
{
border-radius: 0px !important;
}
