Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

In the case of Xamarin in VS, you must add

Theme = "@style/MyThemesss"

to youractivity.cs.

I add this and go on.

The code below creates a set from an array and then, using the ... operator.

var arr=[1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,9,];
var set=new Set(arr);
let setarr=[...set];
console.log(setarr);

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    ImageHolder holder = null;
    if (row == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        row = inflater.inflate(layoutResourceId, parent, false);
        holder = new ImageHolder();
        editText = (EditText) row.findViewById(R.id.id_number_custom);
        loadButton = (ImageButton) row.findViewById(R.id.load_data_button);
        row.setTag(holder);
    } else {
        holder = (ImageHolder) row.getTag();
    }


    holder.editText.setText("Your Value");
    holder.loadButton.setImageBitmap("Your Bitmap Value");
    return row;
}

Have you looked into using a HorizontalScrollView to wrap your list items? That will allow each of your list items to be horizontally scrollable (what you put in there is up to you, and can make them dynamic items similar to ListView). This will work well if you are only after a single row of items.

For some reason, you're re-instantiating the form after you check is_valid(). Forms only get a cleaned_data attribute when is_valid() has been called, and you haven't called it on this new, second instance.

Just get rid of the second form = SearchForm(request.POST) and all should be well.

I was facing the same situation.

I begin by declaring the structures I need:

Set<String> myKeysInSet = null; String[] myArrayOfString = null;

In my case, I have a JSON object and I need all the keys in this JSON to be stored in an array of strings. Using the GSON library, I use JSON.keySet() to get the keys and move to my Set :

myKeysInSet = json_any.keySet();

With this, I have a Set structure with all the keys, as I needed it. So I just need to the values to my Array of Strings. See the code below:

myArrayOfString = myKeysInSet.toArray(new String[myKeysInSet.size()]);

This was my first answer in StackOverflow. Sorry for any error :D

You can use the createRef to change the state of the child component from the parent component. Here are all the steps.

1. Create a method to change the state in the child component.

   2 - Create a reference for the child component in parent component using React.createRef().

   3 - Attach reference with the child component using ref={}.

   4 - Call the child component method using this.yor-reference.current.method.

Parent component

class ParentComponent extends Component {
constructor()
{
this.changeChild=React.createRef()
}
  render() {
    return (
      <div>
        <button onClick={this.changeChild.current.toggleMenu()}>
          Toggle Menu from Parent
        </button>
        <ChildComponent ref={this.changeChild} />
      </div>
    );
  }
}

Child Component

class ChildComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      open: false;
    }
  }

  toggleMenu=() => {
    this.setState({
      open: !this.state.open
    });
  }

  render() {
    return (
      <Drawer open={this.state.open}/>
    );
  }
}

Short:
In you have this problem with a pure Web API project (and thus don't need razor), try to add it anyway, rebuild, then remove it.

Long story:
I had this problem with a brand-new pure Web API project, except that the stacktrace pointed "System.Web.Mvc" as Calling assembly (see Darin's answer). No reference to MVC, Razor or anything like that in my project though...
I decided to add the MVC packages (AspNet.Mvc, AspNet.WebPages and AspNet.Razor) to check if there was any subsequent problem.
The WebApi app then launched perfectly fine. Then I removed the exact same packages and everything was still OK.

Hope it helps someone.

import cv2
img=cv2.imread('my_test.jpg')
img_info = img.shape

This exception occurred in my application and was rather misleading.

It was thrown when I was calling an .aspx page Web Method using an ajax method call, passing a JSON array object. The Web Page method signature contained an array of a strongly-typed .NET object, OrderDetails. The Actual_Qty property was defined as an int, and the JSON object Actual_Qty property contained "4 " (extra space character). After removing the extra space, the conversion was made possible, the Web Page method was successfully reached by the ajax call.

You can put the control you want to center inside a Panel and set the left and right padding values to something larger than the default. As long as they are equal and your control is anchored to the sides of the Panel, then it will appear centered in that Panel. Then you can anchor the container Panel to its parent as needed.

Here's another solution not using date(). not so smart:)

$var = '20/04/2012';
echo implode("-", array_reverse(explode("/", $var)));

Both answers are correct. If you user .TO -method then the semicolumn is OK - but not for the addrecipients-method. There you need to split, e.g. :

                Dim Splitter() As String
                Splitter = Split(AddrMail, ";")
                For Each Dest In Splitter
                    .Recipients.Add (Trim(Dest))
                Next

From the Notes of Fred Swartz (fredosaurus) :

There are two types of methods.

• Instance methods are associated with an object and use the instance variables of that object. This is the default.

• Static methods use no instance variables of any object of the class they are defined in. If you define a method to be static, you will be given a rude message by the compiler if you try to access any instance variables. You can access static variables, but except for constants, this is unusual. Static methods typically take all they data from parameters and compute something from those parameters, with no reference to variables. This is typical of methods which do some kind of generic calculation. A good example of this are the many utility methods in the predefined Math class.

Qualifying a static call

From outside the defining class, an instance method is called by prefixing it with an object, which is then passed as an implicit parameter to the instance method, eg, inputTF.setText("");

A static method is called by prefixing it with a class name, eg, Math.max(i,j);. Curiously, it can also be qualified with an object, which will be ignored, but the class of the object will be used.

Example

Here is a typical static method:

class MyUtils {
    . . .
    //================================================= mean
    public static double mean(int[] p) {
        int sum = 0;  // sum of all the elements
        for (int i=0; i<p.length; i++) {
            sum += p[i];
        }
        return ((double)sum) / p.length;
    }//endmethod mean
    . . .
}

The only data this method uses or changes is from parameters (or local variables of course).

Why declare a method static

The above mean() method would work just as well if it wasn't declared static, as long as it was called from within the same class. If called from outside the class and it wasn't declared static, it would have to be qualified (uselessly) with an object. Even when used within the class, there are good reasons to define a method as static when it could be.

• Documentation. Anyone seeing that a method is static will know how to call it (see below). Similarly, any programmer looking at the code will know that a static method can't interact with instance variables, which makes reading and debugging easier.
• Efficiency. A compiler will usually produce slightly more efficient code because no implicit object parameter has to be passed to the method.

Calling static methods

There are two cases.

Called from within the same class

Just write the static method name. Eg:

// Called from inside the MyUtils class
double avgAtt = mean(attendance);

Called from outside the class

If a method (static or instance) is called from another class, something must be given before the method name to specify the class where the method is defined. For instance methods, this is the object that the method will access. For static methods, the class name should be specified. Eg:

// Called from outside the MyUtils class.
double avgAtt = MyUtils.mean(attendance); 

If an object is specified before it, the object value will be ignored and the the class of the object will be used.

Accessing static variables

Altho a static method can't access instance variables, it can access static variables. A common use of static variables is to define "constants". Examples from the Java library are Math.PI or Color.RED. They are qualified with the class name, so you know they are static. Any method, static or not, can access static variables. Instance variables can be accessed only by instance methods.

Alternate Call

What's a little peculiar, and not recommended, is that an object of a class may be used instead of the class name to access static methods. This is bad because it creates the impression that some instance variables in the object are used, but this isn't the case.

if you care for the whole page. you can use this:

document.body.getBoundingClientRect().top

Try this instead for 'only' scrolling vertical.
(auto scroll needs to be false before it will accept changes)

mypanel.AutoScroll = false;
mypanel.HorizontalScroll.Enabled = false;
mypanel.HorizontalScroll.Visible = false;
mypanel.HorizontalScroll.Maximum = 0;
mypanel.AutoScroll = true;

Since this is a popular error, check out the PHPMailer Wiki on troubleshooting.

Also this worked for me

$mailer->Port = '587';

Both "arrA" & "arrB" can be accessed (print it out). However, can't get a size of "arrB".

What is a problem there?

1. Is 'char[]' incomplete type? or
2. 'sizeof' does not accept the extern variable/ label?

In my program, "arrA" & "arrB" are constant lists and fixed before to compile. I would like to use a label(let me easy to maintenance & save RAM memory).

You can see this example.

// Is this element visible onscreen?
var visible = $(#element).visible( detectPartial );

detectPartial :

• True : the entire element is visible
• false : part of the element is visible

visible is boolean variable which indicates if the element is visible or not.

Look into using grunt to automate this, there are numerous tutorials around, but here's a quick start.

For a folder structure like:

blah/
blah/one.ts
blah/two.ts
blah/example/
blah/example/example.ts
blah/example/package.json
blah/example/Gruntfile.js
blah/example/index.html

You can watch and work with typescript easily from the example folder with:

npm install
grunt

With package.json:

{
  "name": "PROJECT",
  "version": "0.0.1",
  "author": "",
  "description": "",
  "homepage": "",
  "private": true,
  "devDependencies": {
    "typescript": "~0.9.5",
    "connect": "~2.12.0",
    "grunt-ts": "~1.6.4",
    "grunt-contrib-watch": "~0.5.3",
    "grunt-contrib-connect": "~0.6.0",
    "grunt-open": "~0.2.3"
  }
}

And a grunt file:

module.exports = function (grunt) {

  // Import dependencies
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-contrib-connect');
  grunt.loadNpmTasks('grunt-open');
  grunt.loadNpmTasks('grunt-ts');

  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    connect: {
      server: {  // <--- Run a local server on :8089
        options: {
          port: 8089,
          base: './'
        }
      }
    },
    ts: {
      lib: { // <-- compile all the files in ../ to PROJECT.js
        src: ['../*.ts'],
        out: 'PROJECT.js',
        options: {
          target: 'es3',
          sourceMaps: false,
          declaration: true,
          removeComments: false
        }
      },
      example: {  // <--- compile all the files in . to example.js
        src: ['*.ts'],
        out: 'example.js',
        options: {
          target: 'es3',
          sourceMaps: false,
          declaration: false,
          removeComments: false
        }
      }
    },
    watch: { 
      lib: { // <-- Watch for changes on the library and rebuild both
        files: '../*.ts',
        tasks: ['ts:lib', 'ts:example']
      },
      example: { // <--- Watch for change on example and rebuild
        files: ['*.ts', '!*.d.ts'],
        tasks: ['ts:example']
      }
    },
    open: { // <--- Launch index.html in browser when you run grunt
      dev: {
        path: 'http://localhost:8089/index.html'
      }
    }
  });

  // Register the default tasks to run when you run grunt
  grunt.registerTask('default', ['ts', 'connect', 'open', 'watch']);
}

It is just equally spaced hues around the color wheel, starting from 15:

gg_color_hue <- function(n) {
  hues = seq(15, 375, length = n + 1)
  hcl(h = hues, l = 65, c = 100)[1:n]
}

For example:

n = 4
cols = gg_color_hue(n)

dev.new(width = 4, height = 4)
plot(1:n, pch = 16, cex = 2, col = cols)

$resource was meant to retrieve data from an endpoint, manipulate it and send it back. You've got some of that in there, but you're not really leveraging it for what it was made to do.

It's fine to have custom methods on your resource, but you don't want to miss out on the cool features it comes with OOTB.

EDIT: I don't think I explained this well enough originally, but $resource does some funky stuff with returns. Todo.get() and Todo.query() both return the resource object, and pass it into the callback for when the get completes. It does some fancy stuff with promises behind the scenes that mean you can call $save() before the get() callback actually fires, and it will wait. It's probably best just to deal with your resource inside of a promise then() or the callback method.

Standard use

var Todo = $resource('/api/1/todo/:id');

//create a todo
var todo1 = new Todo();
todo1.foo = 'bar';
todo1.something = 123;
todo1.$save();

//get and update a todo
var todo2 = Todo.get({id: 123});
todo2.foo += '!';
todo2.$save();

//which is basically the same as...
Todo.get({id: 123}, function(todo) {
   todo.foo += '!';
   todo.$save();
});

//get a list of todos
Todo.query(function(todos) {
  //do something with todos
  angular.forEach(todos, function(todo) {
     todo.foo += ' something';
     todo.$save();
  });
});

//delete a todo
Todo.$delete({id: 123});

Likewise, in the case of what you posted in the OP, you could get a resource object and then call any of your custom functions on it (theoretically):

var something = src.GetTodo({id: 123});
something.foo = 'hi there';
something.UpdateTodo();

I'd experiment with the OOTB implementation before I went and invented my own however. And if you find you're not using any of the default features of $resource, you should probably just be using $http on it's own.

Update: Angular 1.2 and Promises

As of Angular 1.2, resources support promises. But they didn't change the rest of the behavior.

To leverage promises with $resource, you need to use the $promise property on the returned value.

Example using promises

var Todo = $resource('/api/1/todo/:id');

Todo.get({id: 123}).$promise.then(function(todo) {
   // success
   $scope.todos = todos;
}, function(errResponse) {
   // fail
});

Todo.query().$promise.then(function(todos) {
   // success
   $scope.todos = todos;
}, function(errResponse) {
   // fail
});

Just keep in mind that the $promise property is a property on the same values it was returning above. So you can get weird:

These are equivalent

var todo = Todo.get({id: 123}, function() {
   $scope.todo = todo;
});

Todo.get({id: 123}, function(todo) {
   $scope.todo = todo;
});

Todo.get({id: 123}).$promise.then(function(todo) {
   $scope.todo = todo;
});

var todo = Todo.get({id: 123});
todo.$promise.then(function() {
   $scope.todo = todo;
});

• ^ matches position just before the first character of the string
• $ matches position just after the last character of the string
• . matches a single character. Does not matter what character it is, except newline
• * matches preceding match zero or more times

So, ^.*$ means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. This regex pattern is not very useful.

Let's take a regex pattern that may be a bit useful. Let's say I have two strings The bat of Matt Jones and Matthew's last name is Jones. The pattern ^Matt.*Jones$ will match Matthew's last name is Jones. Why? The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.

Feel free to use an online tool like https://regex101.com/ to test out regex patterns and strings.

I am pretty new to all of this, but I found that if the script is started via CScript.exe (console scripting host) there is no window popping up on exec(): so when running:

cscript myscript.vbs //nologo

any .Exec() calls in the myscript.vbs do not open an extra window, meaning that you can use the first variant of your original solution (using exec).

(Note that the two forward slashes in the above code are intentional, see cscript /?)

This solution is being used for converting multiple string like ("22 44 112 2 34") to an integer list and you can access to the values in a list.

n = input("") # Like : "22 343 455 54445 22332"

if n[:-1] != " ":
n += " "

char = ""
list = []

for i in n :
    if i != " ":
        char += i
    elif i == " ":
        list.append(int(char))
        char = ""

print(list) # Be happy :))))

    curl_setopt($resURL, CURLOPT_FAILONERROR, 1); 
    curl_exec ($resURL); 
    $intReturnCode = curl_getinfo($resURL, CURLINFO_HTTP_CODE); 
    curl_close ($resURL); 
    if ($intReturnCode != 200 && $intReturnCode != 302 && $intReturnCode != 304) { return 0; } else return 1;
}

echo 'google:';

You should instantiate your ArrayList before trying to add items:

If you're using bash you can just say

if grep -q "$SOURCE" <<< "$LIST" ; then
    ...
fi

I'm slightly confused. You should be able to call sqlplus from within the bash script. This may be what you were doing with your first statement

Try Executing the following within your bash script:

#!/bin/bash          
echo Start Executing SQL commands
sqlplus <user>/<password> @file-with-sql-1.sql
sqlplus <user>/<password> @file-with-sql-2.sql

If you want to be able to pass data into your scripts you can do it via SQLPlus by passing arguments into the script:

Contents of file-with-sql-1.sql

 select * from users where username='&1';

Then change the bash script to call sqlplus passing in the value

#!/bin/bash

MY_USER=bob
sqlplus <user>/<password> @file-with-sql-1.sql $MY_USER

I wouldn't use function from one controller into another. A better approach would be to move the common function to a service and then inject the service in both controllers.

Calculate the total size of the database at the end:

(SELECT 
  table_name AS `Table`, 
  round(((data_length + index_length) / 1024 / 1024), 2) `Size in MB` 
  FROM information_schema.TABLES 
  WHERE table_schema = "$DB_NAME"
)
UNION ALL
(SELECT 
  'TOTAL:',
  SUM(round(((data_length + index_length) / 1024 / 1024), 2) )
  FROM information_schema.TABLES 
  WHERE table_schema = "$DB_NAME"
)

Try this

$date = Carbon::parse(date_format($youttimestring,'d/m/Y H:i:s'));
echo $date;

Based on this forum post: https://groups.google.com/forum/#!topic/ggplot2/mK9DR3dKIBU

Sounds like the easiest thing to do is to add a line break (\n) before your x axis, and after your y axis labels. Seems a lot easier (although dumber) than the solutions posted above.

ggplot(mpg, aes(cty, hwy)) + 
    geom_point() + 
    xlab("\nYour_x_Label") + ylab("Your_y_Label\n")

Hope that helps!

If you don't want to do it all by yourself, you can use the random.randrange function.

For example import random; print random.randrange(10, 25, 5) prints a number that is between 10 and 25 (10 included, 25 excluded) and is a multiple of 5. So it would print 10, 15, or 20.

.container {_x000D_
  width:100%;_x000D_

_x000D_
.left {_x000D_
  width:100%;_x000D_
  display:table-cell;_x000D_
  text-align:center;_x000D_
}_x000D_

}

<div class="container">_x000D_
  <div class="left">Left</div>_x000D_
  <div class="right">Right</div>_x000D_
</div

Try this. It worked for me.

If you don't want to use jQuery, take a look at Numeral.js

Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.

Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:

/link/mybackend/?field1=value1&field2=value2&field3=value3

and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET.

So your urlconf would be:

url(r'^link/(?P<backend>\w+?)/$', my_function)

and the view would look like:

def my_function(request, backend):
   data = request.GET

and the reverse would be (after importing urllib):

return "%s?%s" % (redirect('my_function', args=(backend,)),
                  urllib.urlencode(form.cleaned_data))

Edited after comment

The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.

If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.

That said, if all you want to do is store the data, then just put it in the session:

request.session['temp_data'] = form.cleaned_data

I try to avoid the URL class and instead rely on URI. Thus for things that need URL where I would like to do Spring Resource like lookup with out Spring I do the following:

public static URL toURL(URI u, ClassLoader loader) throws MalformedURLException {
    if ("classpath".equals(u.getScheme())) {
        String path = u.getPath();
        if (path.startsWith("/")){
            path = path.substring("/".length());
        }
        return loader.getResource(path);
    }
    else if (u.getScheme() == null && u.getPath() != null) {
        //Assume that its a file.
        return new File(u.getPath()).toURI().toURL();
    }
    else {
        return u.toURL();
    }
}

To create a URI you can use URI.create(..). This way is also better because you control the ClassLoader that will do the resource lookup.

I noticed some other answers trying to parse the URL as a String to detect the scheme. I think its better to pass around URI and use it to parse instead.

I have actually filed an issue a while ago with Spring Source begging them to separate out their Resource code from core so that you don't need all the other Spring stuff.

It's a bug of RadioGroup

RadioButton radioBtn2 = new RadioButton(context);

radioBtn2 without viewId, and generateViewId is in onChildViewAdded()

public void onChildViewAdded(View parent, View child) {
    if (parent == RadioGroup.this && child instanceof RadioButton) {
        int id = child.getId();
        // generates an id if it's missing
        if (id == View.NO_ID) {
            id = View.generateViewId();
            child.setId(id);
        }
        ((RadioButton) child).setOnCheckedChangeWidgetListener(
                mChildOnCheckedChangeListener);
    }

    if (mOnHierarchyChangeListener != null) {
        mOnHierarchyChangeListener.onChildViewAdded(parent, child);
    }
}

so, first radioGroup.addView(radioBtn2), then radioBtn2.setChecked(true);

Like this:

RadioGroup radioGroup = new RadioGroup(context);
RadioButton radioBtn1 = new RadioButton(context);
RadioButton radioBtn2 = new RadioButton(context);
RadioButton radioBtn3 = new RadioButton(context);

radioBtn1.setText("Less");
radioBtn2.setText("Normal");
radioBtn3.setText("More");

radioGroup.addView(radioBtn1);
radioGroup.addView(radioBtn2);
radioGroup.addView(radioBtn3);

radioBtn2.setChecked(true);

just like pure js do preventdefault : in class you should like this create a handler method :

handler(event) {
    event.preventDefault();
    console.log(event);
}

Microsoft has also implemented the operators '<' and '>'. So you use these to compare two dates.

if (date1 < DateTime.Now)
   Console.WriteLine("Less than the current time!");

Hello this is my first time posting so please be patient: my answer was to create a simple property:

public bool Checked { get; set; }

Then to set the data context of the Checkbox (called cb1):

cb1.DataContext = this;

Then to bind the IsChecked proerty of it in the xaml

IsChecked="{Binding Checked}"

The code is like this:

XAML

<CheckBox x:Name="cb1"
          HorizontalAlignment="Left"
          Margin="439,81,0,0"
          VerticalAlignment="Top"
          Height="35" Width="96"
          IsChecked="{Binding Checked}"/>

Code behind

public partial class MainWindow : Window
{
    public bool Checked { get; set; }

    public MainWindow()
    {
        InitializeComponent();

        cb1.DataContext = this;
    }

    private void myyButton_Click(object sender, RoutedEventArgs e)
    {
        MessageBox.Show(Checked.ToString());
    }
}

If you have killall:

os.system("killall -9 iChat");

Or:

os.system("ps -C iChat -o pid=|xargs kill -9")

You're close. This should do the trick:

new {items = new [] {
    new {name = "command" , index = "X", optional = "0"}, 
    new {name = "command" , index = "X", optional = "0"}
}}

If your source was an enumerable of some sort, you might want to do this:

new {items = source.Select(item => new 
{
    name = item.Name, index = item.Index, options = item.Optional
})};

Assuming, as seems to be the case, ${triningIdArray} is a server-side placeholder that is replaced with JS array-literal syntax, just lose the quotes. So:

var traingIds = ${triningIdArray};

not

var traingIds = "${triningIdArray}";

First of all, TCP does not guarantee that everything that you send will be received with the same read at the other end. It only guarantees that all bytes that you send will arrive and in the correct order.

Therefore, you will need to keep building up a buffer when reading from the stream. You will also have to know how large each message is.

The simplest ever is to use a non-typeable ASCII character to mark the end of the packet and look for it in the received data.

TL;DR

SQLCMD -S (LOCAL) -E -V 16 -Q "IF(ISNULL(CAST(SERVERPROPERTY('ProductMajorVersion') AS INT),0)<11) RAISERROR('You need SQL 2012 or later!',16,1)"
IF ERRORLEVEL 1 GOTO :ExitFail

This uses SQLCMD (comes with SQL Server) to connect to the local server instance using Windows auth, throw an error if a version check fails and return the @@ERROR as the command line ERRORLEVEL if >= 16 (and the second line goes to the :ExitFail label if the aforementioned ERRORLEVEL is >= 1).

Watchas, Gotchas & More Info

For SQL 2000+ you can use the SERVERPROPERTY to determine a lot of this info.

While SQL 2008+ supports the ProductMajorVersion & ProductMinorVersion properties, ProductVersion has been around since 2000 (remembering that if a property is not supported the function returns NULL).

If you are interested in earlier versions you can use the PARSENAME function to split the ProductVersion (remembering the "parts" are numbered right to left i.e. PARSENAME('a.b.c', 1) returns c).

Also remember that PARSENAME('a.b.c', 4) returns NULL, because SQL 2005 and earlier only used 3 parts in the version number!

So for SQL 2008+ you can simply use:

SELECT
    SERVERPROPERTY('ProductVersion') AS ProductVersion,
    CAST(SERVERPROPERTY('ProductMajorVersion')  AS INT) AS ProductMajorVersion,
    CAST(SERVERPROPERTY ('ProductMinorVersion') AS INT) AS ProductMinorVersion;

For SQL 2000-2005 you can use:

SELECT
    SERVERPROPERTY('ProductVersion') AS ProductVersion,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) AS ProductVersion_Major,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 2 ELSE 3 END) AS INT) AS ProductVersion_Minor,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 1 ELSE 2 END) AS INT) AS ProductVersion_Revision,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 0 ELSE 1 END) AS INT) AS ProductVersion_Build;

(the PARSENAME(...,0) is a hack to improve readability)

So a check for a SQL 2000+ version would be:

IF (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) < 10) -- SQL2008
OR (
    (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) = 10) -- SQL2008
AND (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 2 ELSE 1 END) AS INT) < 5)  -- R2 (this may need to be 50)
   )
    RAISERROR('You need SQL 2008R2 or later!', 16, 1);

This is a lot simpler if you're only only interested in SQL 2008+ because SERVERPROPERTY('ProductMajorVersion') returns NULL for earlier versions, so you can use:

IF (ISNULL(CAST(SERVERPROPERTY('ProductMajorVersion') AS INT), 0) < 11) -- SQL2012
    RAISERROR('You need SQL 2012 or later!', 16, 1);

And you can use the ProductLevel and Edition (or EngineEdition) properties to determine RTM / SPn / CTPn and Dev / Std / Ent / etc respectively.

SELECT
    CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME) AS ProductVersion,
    CAST(SERVERPROPERTY('ProductLevel') AS SYSNAME)   AS ProductLevel,
    CAST(SERVERPROPERTY('Edition') AS SYSNAME)        AS Edition,
    CAST(SERVERPROPERTY('EngineEdition') AS INT)      AS EngineEdition;

FYI the major SQL version numbers are:

• 8 = SQL 2000
• 9 = SQL 2005
• 10 = SQL 2008 (and 10.5 = SQL 2008R2)
• 11 = SQL 2012
• 12 = SQL 2014
• 13 = SQL 2016
• 14 = SQL 2017

And this all works for SQL Azure too!

EDITED: You may also want to check your DB compatibility level since it could be set to a lower compatibility.

IF EXISTS (SELECT * FROM sys.databases WHERE database_id=DB_ID() AND [compatibility_level] < 110)
    RAISERROR('Database compatibility level must be SQL2008R2 or later (110)!', 16, 1)

This means your MySQL table is corrupted and you need to repair it. Use

myisamchk -r /DB_NAME/wp_posts

from the command line. While you running the repair you should shut down your website temporarily so that no new connections are attempted to your database while its being repaired.

i observe DOM manipulation of angular with JQuery and i did set a finish for my app (some sort of predefined and satisfactory situation that i need for my app-abstract) for example i expect my ng-repeater to produce 7 result and there for i will set an observation function with the help of setInterval for this purpose .

$(document).ready(function(){

  var interval = setInterval(function(){

  if($("article").size() == 7){
     myFunction();
     clearInterval(interval);
  }

  },50);

});

You could find disk intensive full table scans with something like this:

SELECT Disk_Reads DiskReads, Executions, SQL_ID, SQL_Text SQLText, 
   SQL_FullText SQLFullText 
FROM
(
   SELECT Disk_Reads, Executions, SQL_ID, LTRIM(SQL_Text) SQL_Text, 
      SQL_FullText, Operation, Options, 
      Row_Number() OVER 
         (Partition By sql_text ORDER BY Disk_Reads * Executions DESC) 
         KeepHighSQL
   FROM
   (
       SELECT Avg(Disk_Reads) OVER (Partition By sql_text) Disk_Reads, 
          Max(Executions) OVER (Partition By sql_text) Executions, 
          t.SQL_ID, sql_text, sql_fulltext, p.operation,p.options
       FROM v$sql t, v$sql_plan p
       WHERE t.hash_value=p.hash_value AND p.operation='TABLE ACCESS' 
       AND p.options='FULL' AND p.object_owner NOT IN ('SYS','SYSTEM')
       AND t.Executions > 1
   ) 
   ORDER BY DISK_READS * EXECUTIONS DESC
)
WHERE KeepHighSQL = 1
AND rownum <=5;

You could use the rename(1) command:

rename 's/(.*)$/new.$1/' original.filename

Edit: If rename isn't available and you have to rename more than one file, shell scripting can really be short and simple for this. For example, to rename all *.jpg to prefix_*.jpg in the current directory:

for filename in *.jpg; do mv "$filename" "prefix_$filename"; done;

You can use your own function for this.

try it: http://jsfiddle.net/xstLr7aj/

function string_to_slug(str) {
  str = str.replace(/^\s+|\s+$/g, ''); // trim
  str = str.toLowerCase();

  // remove accents, swap ñ for n, etc
  var from = "àáäâèéëêìíïîòóöôùúüûñç·/_,:;";
  var to   = "aaaaeeeeiiiioooouuuunc------";
  for (var i=0, l=from.length ; i<l ; i++) {
    str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
  }

  str = str.replace(/[^a-z0-9 -]/g, '') // remove invalid chars
    .replace(/\s+/g, '-') // collapse whitespace and replace by -
    .replace(/-+/g, '-'); // collapse dashes

  return str;
}
$(document).ready(function() {
    $('#test').submit(function(){
        var val = string_to_slug($('#t').val());
        alert(val);
        return false;
    });
});

Try using CSS.

body {
   margin: 0 0 auto 0;
}

The order is clockwise from the top, so top right bottom left.

The easiest way is

find . -type  f -name '*.extension' 2>/dev/null | xargs grep -i string 

Edit: add 2>/dev/null to kill the error output

To include more file extensions and grep for password throughout the system:

find / -type  f \( -name '*.conf' -o -name "*.log" -o -name "*.bak" \) 2>/dev/null |
xargs grep -i password

You can adjust the plot margins with plot.margin in theme() and then move your axis labels and title with the vjust argument of element_text(). For example :

library(ggplot2)
library(grid)
qplot(rnorm(100)) +
    ggtitle("Title") +
    theme(axis.title.x=element_text(vjust=-2)) +
    theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
    theme(plot.title=element_text(size=15, vjust=3)) +
    theme(plot.margin = unit(c(1,1,1,1), "cm"))

will give you something like this :

If you want more informations about the different theme() parameters and their arguments, you can just enter ?theme at the R prompt.

Hope it helps!

You can use nuget.exe to restore your packages or with NuGet 2.7, or above, installed you can simply compile your solution in Visual Studio, which will also restore the missing packages.

For NuGet.exe you can run the following command for each project.

nuget install packages.config

Or with NuGet 2.7 you can restore all packages in the solution using the command line.

nuget restore YourSolution.sln

Both of these will pull down the packages. Your project files will not be modified however when running this command so the project should already have a reference to the NuGet packages. If this is not the case then you can use Visual Studio to install the packages.

With NuGet 2.7, and above, Visual Studio will automatically restore missing NuGet packages when you build your solution so there is no need to use NuGet.exe.

To update all the packages in your solution, first restore them, and then you can either use NuGet.exe to update the packages or from within Visual Studio you can update the packages from the Package Manager Console window, or finally you can use the Manage Packages dialog.

From the command line you can update packages in the solution to the latest version available from nuget.org.

nuget update YourSolution.sln

Note that this will not run any PowerShell scripts in any NuGet packages.

From within Visual Studio you can use the Package Manager Console to also update the packages. This has the benefit that any PowerShell scripts will be run as part of the update where as using NuGet.exe will not run them. The following command will update all packages in every project to the latest version available from nuget.org.

Update-Package

You can also restrict this down to one project.

Update-Package -Project YourProjectName

If you want to reinstall the packages to the same versions as were previously installed then you can use the -reinstall argument with Update-Package command.

Update-Package -reinstall

You can also restrict this down to one project.

Update-Package -reinstall -Project YourProjectName

The -reinstall option will first uninstall and then install the package back again into a project.

Or, you can update the packages using the Manage Packages dialog.

Updates:

• 2013/07/10 - Updated with information about nuget restore in NuGet 2.7

To translate your *nix style command script to windows/command batch style it would go like this:

SET PROJ_HOME=%USERPROFILE%/proj/111
SET PROJECT_BASEDIR=%PROJ_HOME%/exercises/ex1
mkdir "%PROJ_HOME%"

mkdir on windows doens't have a -p parameter : from the MKDIR /? help:

MKDIR creates any intermediate directories in the path, if needed.

which basically is what mkdir -p (or --parents for purists) on *nix does, as taken from the man guide

Use this also

NSString *ChkStr = [MyString substringWithRange:NSMakeRange(5, 26)];

Note - Your NSMakeRange(start, end) should be NSMakeRange(start, end- start);

Here's how to look in the documentation.

First, you're dealing with IO, so look in the java.io package.

There are two classes that look interesting: FileFilter and FileNameFilter. When I clicked on the first, it showed me that there was a a listFiles() method in the File class. And the documentation for that method says:

Returns an array of abstract pathnames denoting the files in the directory denoted by this abstract pathname.

Scrolling up in the File JavaDoc, I see the constructors. And that's really all I need to be able to create a File instance and call listFiles() on it. Scrolling still further, I can see some information about how files are named in different operating systems.

$text="abc1234567890";

// truncate to 4 chars

echo substr(str_pad($text,4),0,4);

This avoids the problem of truncating a 4 char string to 10 chars .. (i.e. source is smaller than the required)

Looking at it from a practical rather than theoretical standpoint, on a 32 bit Windows system, the maximum total amount of memory available for a single process is 2 GB. You can break the limit by going to a 64 bit operating system with much more physical memory, but whether to do this or look for alternatives depends very much on your intended users and their budgets. You can also extend it somewhat using PAE.

The type of the array is very important, as default structure alignment on many compilers is 8 bytes, which is very wasteful if memory usage is an issue. If you are using Visual C++ to target Windows, check out the #pragma pack directive as a way of overcoming this.

Another thing to do is look at what in memory compression techniques might help you, such as sparse matrices, on the fly compression, etc... Again this is highly application dependent. If you edit your post to give some more information as to what is actually in your arrays, you might get more useful answers.

Edit: Given a bit more information on your exact requirements, your storage needs appear to be between 7.6 GB and 76 GB uncompressed, which would require a rather expensive 64 bit box to store as an array in memory in C++. It raises the question why do you want to store the data in memory, where one presumes for speed of access, and to allow random access. The best way to store this data outside of an array is pretty much based on how you want to access it. If you need to access array members randomly, for most applications there tend to be ways of grouping clumps of data that tend to get accessed at the same time. For example, in large GIS and spatial databases, data often gets tiled by geographic area. In C++ programming terms you can override the [] array operator to fetch portions of your data from external storage as required.

I had this problem. I solved it with downloading 64x of the Java. Here is the link: http://javadl.sun.com/webapps/download/AutoDL?BundleId=87443

Try this for WPF

StreamResourceInfo sri = Application.GetResourceStream(new Uri("pack://application:,,,/WpfGifImage001;Component/Images/Progess_Green.gif"));
picBox1.Image = System.Drawing.Image.FromStream(sri.Stream);

Here is a very slight improvement to user1387483's answer using an immediate function:

(function() {
  $("*").on( 'touchstart', function() {
    $(this).trigger('hover') ;
  } ).on('touchend', function() {
    $(this).trigger('hover') ;
  } ) ;
})() ;

Also, I agree with Boz that this appears to be the "neatest, most compliant solution".

You can rename your Conda env by just renaming the env folder. Here is the proof:

You can find your Conda env folder inside of C:\ProgramData\Anaconda3\envs or you can enter conda env list to see the list of conda envs and its location.

You can do:

char str[] ="Stackoverflow Serverfault";
char piece1[20] = ""
    ,piece2[20] = "";
char * p;

p = strtok (str," "); // call the strtok with str as 1st arg for the 1st time.
if (p != NULL) // check if we got a token.
{
    strcpy(piece1,p); // save the token.
    p = strtok (NULL, " "); // subsequent call should have NULL as 1st arg.
    if (p != NULL) // check if we got a token.
        strcpy(piece2,p); // save the token.
}
printf("%s :: %s\n",piece1,piece2); // prints Stackoverflow :: Serverfault

If you expect more than one token its better to call the 2nd and subsequent calls to strtok in a while loop until the return value of strtok becomes NULL.

Activator.CreateInstance() returns an object, which doesn't have an Output method.

It looks like you come from dynamic programming languages? C# is definetly not that, and what you are trying to do will be difficult.

Since you are loading a specific dll from a specific location, maybe you just want to add it as a reference to your console application?

If you absolutely want to load the assembly via Assembly.Load, you will have to go via reflection to call any members on c

Something like type.GetMethod("Output").Invoke(c, null); should do it.

Use the timestamp you get by calling valueOf on the date object:

var diff = date2.valueOf() - date1.valueOf();
var diffInHours = diff/1000/60/60; // Convert milliseconds to hours

for i in {1..600}
do
    n=$(($i%5))
    wget http://example.com/search/link$n
done

In addition to these other answers, I've sped up projects with multiple submodules by using parallel submodule fetching (since Git 2.8 in early 2016).

This can be done with git fetch --recurse-submodules -j8 and set with git config --global submodule.fetchJobs 8, or however many cores you have/want to use.

They follow the same naming rules as variable names. Therefore they should not contain spaces.

Also what you are suggesting would be very bad practice anyway.

I've used Sothink SWF decompiler a couple of times, the only problem is that as project gets more complex, the output of decompiler gets harder to compile back again. But it ensures that you can get your .as files most of the time, compilable fla is a question.

PID=4 does not show up in Task Manager even after placing check mark on 'Show processes from all users". Well there is only one user.

However, netstat -b shows multiple connections poiting to the same PID=4 which on this computer displayed the following.

I have only chosen those pertaining to TCP protocol.

This was acquired while trouble shooting IIS which did not start after trying out many others. I do not think you should stop this process.

You can try to use CDATA to put all your symbols that don't work.

An example of something that will work in XML:

<![CDATA[
function matchwo(a,b) {
    if (a < b && a < 0) {
        return 1;
   } else {
       return 0;
   }
}
]]>

And of course you can use < and >.

If you are referring to the System.Net.HttpClient in .NET 4.5, you can get the content returned by GetAsync using the HttpResponseMessage.Content property as an HttpContent-derived object. You can then read the contents to a string using the HttpContent.ReadAsStringAsync method or as a stream using the ReadAsStreamAsync method.

The HttpClient class documentation includes this example:

  HttpClient client = new HttpClient();
  HttpResponseMessage response = await client.GetAsync("http://www.contoso.com/");
  response.EnsureSuccessStatusCode();
  string responseBody = await response.Content.ReadAsStringAsync();

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

Only the shortcut syntax worked for me *ngIf.

(I think it's the later versions that use this syntax if I'm not mistaken)

<div *ngIf="haystack.indexOf('needle') > -1">
</div>

or

<div *ngIf="haystack.includes('needle')">
</div>

I've solved the problem by add attribute 'defer' to the 'script' element.

My terminal was just acting silly, not printing out åäö. I found (and set) this setting:

Under Terminal -> Preferences... -> Profiles -> Advanced.

Seems to have fixed my problem.

I organize packages by feature, not by patterns or implementation roles. I think packages like:

• beans
• factories
• collections

are wrong.

I prefer, for example:

• orders
• store
• reports

so I can hide implementation details through package visibility. Factory of orders should be in the orders package so details about how to create an order are hidden.

You can specify the version of Python for the driver by setting the appropriate environment variables in the ./conf/spark-env.sh file. If it doesn't already exist, you can use the spark-env.sh.template file provided which also includes lots of other variables.

Here is a simple example of a spark-env.sh file to set the relevant Python environment variables:

#!/usr/bin/env bash

# This file is sourced when running various Spark programs.
export PYSPARK_PYTHON=/usr/bin/python3       
export PYSPARK_DRIVER_PYTHON=/usr/bin/ipython

In this case it sets the version of Python used by the workers/executors to Python3 and the driver version of Python to iPython for a nicer shell to work in.

If you don't already have a spark-env.sh file, and don't need to set any other variables, this one should do what you want, assuming that paths to the relevant python binaries are correct (verify with which). I had a similar problem and this fixed it.

You can't - a set is unordered, so there's no index provided. You'll have to declare an int, as you say. Just remember that the next time you call keySet() you won't necessarily get the results in the same order.

That's because you created a Web Site instead of a Web Application. The cs/vb files can only be seen in a Web Application, but in a website you can't have a separate cs/vb file.

Edit: In the website you can add a cs file behavior like..

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

Some good answers here but none cover the case of your start time being in a different day than your end time. If you need to straddle the day boundary, then something like this may help:

TimeSpan start = TimeSpan.Parse("22:00"); // 10 PM
TimeSpan end = TimeSpan.Parse("02:00");   // 2 AM
TimeSpan now = DateTime.Now.TimeOfDay;

if (start <= end)
{
    // start and stop times are in the same day
    if (now >= start && now <= end)
    {
        // current time is between start and stop
    }
}
else
{
    // start and stop times are in different days
    if (now >= start || now <= end)
    {
       // current time is between start and stop
    }
}

Note that in this example the time boundaries are inclusive and that this still assumes less than a 24-hour difference between start and stop.

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_
_x000D_
  }_x000D_
_x000D_
}

<h1 class="keyword-title">Search results for<span class="securitySearchQuery"> "hi".</span></h1>

Dictionaries in python have no order. You could use a list of tuples as your data structure instead.

d = { 'a': 10, 'b': 20, 'c': 30}
newd = [('a',10), ('b',20), ('c',30)]

Then this code could be used to find the locations of keys with a specific value

locations = [i for i, t in enumerate(newd) if t[0]=='b']

>>> [1]

Have you tried url-encoding the data ? cURL can take care of that for you :

curl -H "Content-type: text/xml" --data-urlencode "<XmlContainer xmlns='sads'..." http://myapiurl.com/service.svc/

I create the tag like this and then I push it to GitHub:

git tag -a v1.1 -m "Version 1.1 is waiting for review"
git push --tags

Counting objects: 1, done.
Writing objects: 100% (1/1), 180 bytes, done.
Total 1 (delta 0), reused 0 (delta 0)
To [email protected]:neoneye/triangle_draw.git
 * [new tag]         v1.1 -> v1.1

Example:

2.032 MB (2,131,022 bytes)

$u=($mbox.TotalItemSize.value).tostring()

$u=$u.trimend(" bytes)") #yields 2.032 MB (2,131,022

$u=$u.Split("(") #yields `$u[1]` as 2,131,022

$uI=[int]$u[1]

The result is 2131022 in integer form.

var date=new Date();

//here I am using "-30" to subtract 30 minutes from the current time.
var minute=date.setMinutes(date.getMinutes()-30); 

console.log(minute) //it will print the time and date according to the above condition in Unix-timestamp format.

you can convert Unix timestamp into conventional time by using new Date().for example

var extract=new Date(minute)
console.log(minute)//this will print the time in the readable format.

Couldn't you also make the property part of the scopes parent?

$scope.$parent.property = somevalue;

I'm not saying it's right but it works.

let's suppose

x=50
y=5

then

z=$((x/y))

this will work properly . But if you want to use / operator in case statements than it can't resolve it. In that case use simple strings like div or devide or something else. See the code

Why don't you declare a string instead of writing a long lines into the layout file. For this you have to declare a line of code into layout file 'android:text="@string/text"' and go to the \\app\src\main\res\values\strings.xml and add a line of code ' Your multiline text here' Also use '\n' to break the line from any point else the line will automatically be adjusted.

Your code is drawing the center of the baseline of the text, at the center of the view. In order to center the text at some point, x, y, you need to calculate the center of the text, and put that at the point.

This method will draw text centered at the point x, y. If you pass it the center of your view, it will draw the text centered.

private void drawTextCentered(String text, int x, int y, Paint paint, Canvas canvas) {
    int xPos = x - (int)(paint.measureText(text)/2);
    int yPos = (int) (y - ((textPaint.descent() + textPaint.ascent()) / 2)) ;

    canvas.drawText(text, xPos, yPos, textPaint);
}

Under normal circumstances,out of bound of array when you encounter the error. So,check uo your array subscript.

One way is to use re.sub, that's my preferred way.

import re
my_str = "hey th~!ere"
my_new_string = re.sub('[^a-zA-Z0-9 \n\.]', '', my_str)
print my_new_string

Output:

hey there

Another way is to use re.escape:

import string
import re

my_str = "hey th~!ere"

chars = re.escape(string.punctuation)
print re.sub(r'['+chars+']', '',my_str)

Output:

hey there

Just a small tip about parameters style in python by PEP-8 parameters should be remove_special_chars and not removeSpecialChars

Also if you want to keep the spaces just change [^a-zA-Z0-9 \n\.] to [^a-zA-Z0-9\n\.]

You can read a CSV file with headers into a NumPy structured array with np.genfromtxt. For example:

import numpy as np

csv_fname = 'file.csv'
with open(csv_fname, 'w') as fp:
    fp.write("""\
"A","B","C","D","E","F","timestamp"
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291111964948E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291113113366E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291120650486E12
""")

# Read the CSV file into a Numpy record array
r = np.genfromtxt(csv_fname, delimiter=',', names=True, case_sensitive=True)
print(repr(r))

which looks like this:

array([(611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111196e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111311e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29112065e+12)],
      dtype=[('A', '<f8'), ('B', '<f8'), ('C', '<f8'), ('D', '<f8'), ('E', '<f8'), ('F', '<f8'), ('timestamp', '<f8')])

You can access a named column like this r['E']:

array([1715.37476, 1715.37476, 1715.37476])

Note: this answer previously used np.recfromcsv to read the data into a NumPy record array. While there was nothing wrong with that method, structured arrays are generally better than record arrays for speed and compatibility.

var contentString = "Location: " + results[1].formatted_address;    
google.maps.event.addListener(marker,'click', (function(){ 
    infowindow.close();
    infowindow = new google.maps.InfoWindow({
        content: contentString
    });
    infowindow.open(map, marker);
}));

If you use SDK Manager in Eclipse:

Option 1: Right-click on eclipse.exe and select "Run As Administrator".

Option 2: If you don't want to start Eclipse.exe as Administrator just install/copy Eclipse installation files from "C:\program files\Eclipse ADT Bundle\" to some unprotected folder, like "D:\android\". Run "D:\android\eclipse\eclipse.exe", select menu item "Window => Preferences => Android" and change "SDK Location" to "D:\android\sdk\". After that you'll be able to install new packages in Android SDK Manager.

Depending on how large and how well-written the original code was, it might be worth starting again in your favourite language (which might still be C++) and learning from any mistakes made in the last version. Didn't someone once say about writing one to throw away?

n.b. Clearly if this is a huge product, then it may not be worth the time.

len(queue) should give you the result, 3 in this case.

Specifically, len(object) function will call object.__len__ method [reference link]. And the object in this case is deque, which implements __len__ method (you can see it by dir(deque)).

queue= deque([])   #is this length 0 queue?

Yes it will be 0 for empty deque.

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

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

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

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

I found something very useful on this site when I was searching for an answer on this question. You can check it out at http://www.codingforums.com/javascript-programming/230503-how-get-margin-left-value.html. The part that helped me was the following:

/***

 *   http://robertnyman.com/2006/04/24/get-the-rendered-style-of-an-element

 ***/
var getStyle = function(e, styleName) {
  var styleValue = "";
  if (document.defaultView && document.defaultView.getComputedStyle) {
    styleValue = document.defaultView.getComputedStyle(e, "").getPropertyValue(styleName);
  } else if (e.currentStyle) {
    styleName = styleName.replace(/\-(\w)/g, function(strMatch, p1) {
      return p1.toUpperCase();
    });

You are trying to alter the behaviour of onclick inside the same function call. Try it like this:

Anchor tag

<a id="loginLink" onclick="toggleTable();" href="#">Login</a>

JavaScript

function toggleTable() {
    var lTable = document.getElementById("loginTable");
    lTable.style.display = (lTable.style.display == "table") ? "none" : "table";
}

Use the Activity Monitor. It's the last toolbar in the top bar. It will show you a list of "Recent Expensive Queries". You can double-click them to see the execution plan, etc.

You can/should set your parameter to value to DBNull.Value;

if (variable == "")
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = DBNull.Value;
}
else
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = variable;
}

Or you can leave your server side set to null and not pass the param at all.

I really like the Broken Arrow's solution above in this post. I have just improved/changed it a bit so that what was called labels can be toggled and are not considered options. I have used a small piece of jQuery, but this could be done without jQuery.

I have replaced intermediate labels (no leaf labels) with links, which call a function on click. This function is in charge of toggling the next div of the clicked link, so that it expands/collapses the options. This avoids the possibility of selecting an intermediate element in the hierarchy, which usually is something desired. Making a variant that allows to select intermediate elements should be easy.

This is the modified html:

<div class="NestedSelect">
    <a onclick="toggleDiv(this)">Fruit</a>
    <div>
        <label>
            <input type="radio" name="MySelectInputName"><span>Apple</span></label>
        <label>
            <input type="radio" name="MySelectInputName"><span>Banana</span></label>
        <label>
            <input type="radio" name="MySelectInputName"><span>Orange</span></label>
    </div>

    <a onclick="toggleDiv(this)">Drink</a>
    <div>
        <label>
            <input type="radio" name="MySelectInputName"><span>Water</span></label>

        <a onclick="toggleDiv(this)">Soft</a>
        <div>
            <label>
                <input type="radio" name="MySelectInputName"><span>Cola</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Soda</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Lemonade</span></label>
        </div>

        <a onclick="toggleDiv(this)">Hard</a>
        <div>
            <label>
                <input type="radio" name="MySelectInputName"><span>Bear</span></label>

                <input type="radio" name="MySelectInputName"><span>Whisky</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Vodka</span></label>

                <input type="radio" name="MySelectInputName"><span>Gin</span></label>
        </div>
    </div>
</div>

A small javascript/jQuery function:

function toggleDiv(element) {
    $(element).next('div').toggle('medium');
}

And the css:

.NestedSelect {
    display: inline-block;
    height: 100%;
    border: 1px Black solid;
    overflow-y: scroll;
}

.NestedSelect a:hover, .NestedSelect span:hover  {
    background-color: #0092ff;
    color: White;
    cursor: pointer;
}

.NestedSelect input[type="radio"] {
    display: none;
}

.NestedSelect input[type="radio"] + span {
    display: block;
    padding-left: 0px;
    padding-right: 5px;
}

.NestedSelect input[type="radio"]:checked + span {
    background-color: Black;
    color: White;
}

.NestedSelect div {
    display: none;
    margin-left: 15px;
    border-left: 1px black
    solid;
}

.NestedSelect label > span:before, .NestedSelect a:before{
    content: '- ';
}

.NestedSelect a {
    display: block;
}

Running sample in JSFiddle

I've had the same error as you have and it turned out that there was nothing wrong with the code. The problem was that the webserver was sending the wrong Content-Type header.

Try wireshark or something similar to see what content-type the webserver is sending.

In addition Some Sharepoint databases contain hyphens in their names. Using square brackets in SQL Statements allow the names to be parsed correctly.

I was able to set up github actions to automatically commit the results of a node build command (yarn build in my case but it should work with npm too) to the gh-pages branch whenever a new commit is pushed to master.

While not completely ideal as i'd like to avoid committing the built files, it seems like this is currently the only way to publish to github pages.

I based my workflow off of this guide for a different react library, and had to make the following changes to get it to work for me:

• updated the "setup node" step to use the version found here since the one from the sample i was basing it off of was throwing errors because it could not find the correct action.
• remove the line containing yarn export because that command does not exist and it doesn't seem to add anything helpful (you may also want to change the build line above it to suit your needs)
• I also added an env directive to the yarn build step so that I can include the SHA hash of the commit that generated the build inside my app, but this is optional

Here is my full github action:

name: github pages

on:
    push:
        branches:
        - master

jobs:
    deploy:
        runs-on: ubuntu-18.04
        steps:
        - uses: actions/checkout@v2

        - name: Setup Node
            uses: actions/setup-node@v2-beta
            with:
            node-version: '12'

        - name: Get yarn cache

        - run: yarn build
            env:

        - name: Deploy

            with:
            github_token: ${{ secrets.GITHUB_TOKEN }}
            publish_dir: ./build

Alternative solution

The docs for next.js also provides instructions for setting up with Vercel which appears to be a hosting service for node.js apps similar to github pages. I have not tried this though and so cannot speak to how well it works.

I like to use find which is first assigned to variable and IFS switched to new line as follow:

FilesFound=$(find . -name "*.txt")

IFSbkp="$IFS"
IFS=$'\n'
counter=1;
for file in $FilesFound; do
    echo "${counter}: ${file}"
    let counter++;
done
IFS="$IFSbkp"

As commented by @Konrad Rudolph this will not work with "new lines" in file name. I still think it is handy as it covers most of the cases when you need to loop over command output.

Facebook Developer Wiki (unofficial) contain not only list of FQL error codes but others too it's somehow updated but not contain full list of possible error codes.

There is no any official or updated (I mean really updated) list of error codes returned by Graph API. Every list that can be found online is outdated and not help that much...

There is official list describing some of API Errors and basic recovery tactics. Also there is couple of offcial lists for specific codes:

• Graph API › Errors
• OAuth Errors
• Credits Error codes - Facebook Credits is unsupported from Sep 2013
• Payments Error codes

Show Detail - For use in a split view controller, replaces the detail/secondary view controller when in an expanded 2 column interface, otherwise if collapsed to 1 column it will push in a navigation controller
Example: In Messages, tapping a conversation will show the conversation details - replacing the view controller on the right when in a two column layout, or push the conversation when in a single column layout

Present Modally - Presents a view controller in various animated fashions as defined by the Presentation option, covering the previous view controller - most commonly used to present a view controller that animates up from the bottom and covers the entire screen on iPhone, or on iPad it's common to present it as a centered box that darkens the presenting view controller
Example: Selecting Touch ID & Passcode in Settings

Popover Presentation - When run on iPad, the destination appears in a popover, and tapping anywhere outside of this popover will dismiss it, or on iPhone popovers are supported as well but by default it will present the destination modally over the full screen
Example: Tapping the + button in Calendar

Custom - You may implement your own custom segue and have control over its behavior

The deprecated segues are essentially the non-adaptive equivalents of those described above. These segue types were deprecated in iOS 8: Push, Modal, Popover, Replace.

For more info, you may read over the Using Segues documentation which also explains the types of segues and how to use them in a Storyboard. Also check out Session 216 Building Adaptive Apps with UIKit from WWDC 2014. They talked about how you can build adaptive apps using these new Adaptive Segues, and they built a demo project that utilizes these segues.

In 2021 - use ES6 Template Literals for this task. If you need IE11 Support - use a transpiler.

let a = `something       something`;

Template Literals are fast, powerful and produce cleaner code.

If you need IE11 support and you don't have transpiler, stay strong and use \xa0 - it is a NO-BREAK SPACE char.

Reference from UTF-8 encoding table and Unicode characters, you can write as below:

var a = 'something' + '\xa0\xa0\xa0\xa0\xa0\xa0\xa0' + 'something';

Try something like this:

df.select([c for c in df.columns if c in ['_2','_4','_5']]).show()

Here is a working example:

@echo off
:ask
@echo echo Would you like to use developer mode?(Y/N)
set INPUT=
set /P INPUT=Type input: %=%
If /I "%INPUT%"=="y" goto yes 
If /I "%INPUT%"=="n" goto no
goto ask
:yes
@echo you select yes
goto exit
:no
@echo you select no
goto exit
:exit
@pause

Another way

_details.Sort((s1, s2) => s1.CompareTo(s2)); 

You can use the rather sensibly named xpath function called concat here

<a>
   <xsl:attribute name="href">
      <xsl:value-of select="concat('myText:', /*/properties/property[@name='report']/@value)" />
   </xsl:attribute>
</a>  

Of course, it doesn't have to be text here, it can be another xpath expression to select an element or attribute. And you can have any number of arguments in the concat expression.

Do note, you can make use of Attribute Value Templates (represented by the curly braces) here to simplify your expression

<a href="{concat('myText:', /*/properties/property[@name='report']/@value)}"></a>

If all you are trying to do is find the IP address that corresponds to a domain name, like google.com, this is very easy on every machine connected to the Internet.

Simply run the ping command from any command prompt. Typing something like

ping google.com

will give you (among other things) that information.

• packed means it will use the smallest possible space for struct Ball - i.e. it will cram fields together without padding
• aligned means each struct Ball will begin on a 4 byte boundary - i.e. for any struct Ball, its address can be divided by 4

These are GCC extensions, not part of any C standard.

You can dispatch a click event, though this is not the same as a real click. For instance, it can't be used to trick a cross-domain iframe document into thinking it was clicked.

All modern browsers support document.elementFromPoint and HTMLElement.prototype.click(), since at least IE 6, Firefox 5, any version of Chrome and probably any version of Safari you're likely to care about. It will even follow links and submit forms:

document.elementFromPoint(x, y).click();

https://developer.mozilla.org/En/DOM:document.elementFromPoint https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click

The current HTML5 draft also allows ommitting the href attribute completely.

If the a element has no href attribute, then the element represents a placeholder for where a link might otherwise have been placed, if it had been relevant.

To answer your question: Yes it's valid.

Simplest ways:

Date date = Date.valueOf("2000-1-1");
LocalDate localdate = LocalDate.of(2000,1,1);
LocalDateTime localDateTime = LocalDateTime.of(2000,1,1,0,0);

A function pointer is a variable that contains the address of a function. Since it is a pointer variable though with some restricted properties, you can use it pretty much like you would any other pointer variable in data structures.

The only exception I can think of is treating the function pointer as pointing to something other than a single value. Doing pointer arithmetic by incrementing or decrementing a function pointer or adding/subtracting an offset to a function pointer isn't really of any utility as a function pointer only points to a single thing, the entry point of a function.

The size of a function pointer variable, the number of bytes occupied by the variable, may vary depending on the underlying architecture, e.g. x32 or x64 or whatever.

The declaration for a function pointer variable needs to specify the same kind of information as a function declaration in order for the C compiler to do the kinds of checks that it normally does. If you don't specify a parameter list in the declaration/definition of the function pointer, the C compiler will not be able to check the use of parameters. There are cases when this lack of checking can be useful however just remember that a safety net has been removed.

Some examples:

int func (int a, char *pStr);    // declares a function

int (*pFunc)(int a, char *pStr);  // declares or defines a function pointer

int (*pFunc2) ();                 // declares or defines a function pointer, no parameter list specified.

int (*pFunc3) (void);             // declares or defines a function pointer, no arguments.

The first two declararations are somewhat similar in that:

• func is a function that takes an int and a char * and returns an int
• pFunc is a function pointer to which is assigned the address of a function that takes an int and a char * and returns an int

So from the above we could have a source line in which the address of the function func() is assigned to the function pointer variable pFunc as in pFunc = func;.

Notice the syntax used with a function pointer declaration/definition in which parenthesis are used to overcome the natural operator precedence rules.

int *pfunc(int a, char *pStr);    // declares a function that returns int pointer
int (*pFunc)(int a, char *pStr);  // declares a function pointer that returns an int

Several Different Usage Examples

Some examples of usage of a function pointer:

int (*pFunc) (int a, char *pStr);    // declare a simple function pointer variable
int (*pFunc[55])(int a, char *pStr); // declare an array of 55 function pointers
int (**pFunc)(int a, char *pStr);    // declare a pointer to a function pointer variable
struct {                             // declare a struct that contains a function pointer
    int x22;
    int (*pFunc)(int a, char *pStr);
} thing = {0, func};                 // assign values to the struct variable
char * xF (int x, int (*p)(int a, char *pStr));  // declare a function that has a function pointer as an argument
char * (*pxF) (int x, int (*p)(int a, char *pStr));  // declare a function pointer that points to a function that has a function pointer as an argument

You can use variable length parameter lists in the definition of a function pointer.

int sum (int a, int b, ...);
int (*psum)(int a, int b, ...);

Or you can not specify a parameter list at all. This can be useful but it eliminates the opportunity for the C compiler to perform checks on the argument list provided.

int  sum ();      // nothing specified in the argument list so could be anything or nothing
int (*psum)();
int  sum2(void);  // void specified in the argument list so no parameters when calling this function
int (*psum2)(void);

C style Casts

You can use C style casts with function pointers. However be aware that a C compiler may be lax about checks or provide warnings rather than errors.

int sum (int a, char *b);
int (*psplsum) (int a, int b);
psplsum = sum;               // generates a compiler warning
psplsum = (int (*)(int a, int b)) sum;   // no compiler warning, cast to function pointer
psplsum = (int *(int a, int b)) sum;     // compiler error of bad cast generated, parenthesis are required.

Compare Function Pointer to Equality

You can check that a function pointer is equal to a particular function address using an if statement though I am not sure how useful that would be. Other comparison operators would seem to have even less utility.

static int func1(int a, int b) {
    return a + b;
}

static int func2(int a, int b, char *c) {
    return c[0] + a + b;
}

static int func3(int a, int b, char *x) {
    return a + b;
}

static char *func4(int a, int b, char *c, int (*p)())
{
    if (p == func1) {
        p(a, b);
    }
    else if (p == func2) {
        p(a, b, c);      // warning C4047: '==': 'int (__cdecl *)()' differs in levels of indirection from 'char *(__cdecl *)(int,int,char *)'
    } else if (p == func3) {
        p(a, b, c);
    }
    return c;
}

An Array of Function Pointers

And if you want to have an array of function pointers each of the elements of which the argument list has differences then you can define a function pointer with the argument list unspecified (not void which means no arguments but just unspecified) something like the following though you may see warnings from the C compiler. This also works for a function pointer parameter to a function:

int(*p[])() = {       // an array of function pointers
    func1, func2, func3
};
int(**pp)();          // a pointer to a function pointer


p[0](a, b);
p[1](a, b, 0);
p[2](a, b);      // oops, left off the last argument but it compiles anyway.

func4(a, b, 0, func1);
func4(a, b, 0, func2);  // warning C4047: 'function': 'int (__cdecl *)()' differs in levels of indirection from 'char *(__cdecl *)(int,int,char *)'
func4(a, b, 0, func3);

    // iterate over the array elements using an array index
for (i = 0; i < sizeof(p) / sizeof(p[0]); i++) {
    func4(a, b, 0, p[i]);
}
    // iterate over the array elements using a pointer
for (pp = p; pp < p + sizeof(p)/sizeof(p[0]); pp++) {
    (*pp)(a, b, 0);          // pointer to a function pointer so must dereference it.
    func4(a, b, 0, *pp);     // pointer to a function pointer so must dereference it.
}

C style namespace Using Global struct with Function Pointers

You can use the static keyword to specify a function whose name is file scope and then assign this to a global variable as a way of providing something similar to the namespace functionality of C++.

In a header file define a struct that will be our namespace along with a global variable that uses it.

typedef struct {
   int (*func1) (int a, int b);             // pointer to function that returns an int
   char *(*func2) (int a, int b, char *c);  // pointer to function that returns a pointer
} FuncThings;

extern const FuncThings FuncThingsGlobal;

Then in the C source file:

#include "header.h"

// the function names used with these static functions do not need to be the
// same as the struct member names. It's just helpful if they are when trying
// to search for them.
// the static keyword ensures these names are file scope only and not visible
// outside of the file.
static int func1 (int a, int b)
{
    return a + b;
}

static char *func2 (int a, int b, char *c)
{
    c[0] = a % 100; c[1] = b % 50;
    return c;
}

const FuncThings FuncThingsGlobal = {func1, func2};

This would then be used by specifying the complete name of global struct variable and member name to access the function. The const modifier is used on the global so that it can not be changed by accident.

int abcd = FuncThingsGlobal.func1 (a, b);

Application Areas of Function Pointers

A DLL library component could do something similar to the C style namespace approach in which a particular library interface is requested from a factory method in a library interface which supports the creation of a struct containing function pointers.. This library interface loads the requested DLL version, creates a struct with the necessary function pointers, and then returns the struct to the requesting caller for use.

typedef struct {
    HMODULE  hModule;
    int (*Func1)();
    int (*Func2)();
    int(*Func3)(int a, int b);
} LibraryFuncStruct;

int  LoadLibraryFunc LPCTSTR  dllFileName, LibraryFuncStruct *pStruct)
{
    int  retStatus = 0;   // default is an error detected

    pStruct->hModule = LoadLibrary (dllFileName);
    if (pStruct->hModule) {
        pStruct->Func1 = (int (*)()) GetProcAddress (pStruct->hModule, "Func1");
        pStruct->Func2 = (int (*)()) GetProcAddress (pStruct->hModule, "Func2");
        pStruct->Func3 = (int (*)(int a, int b)) GetProcAddress(pStruct->hModule, "Func3");
        retStatus = 1;
    }

    return retStatus;
}

void FreeLibraryFunc (LibraryFuncStruct *pStruct)
{
    if (pStruct->hModule) FreeLibrary (pStruct->hModule);
    pStruct->hModule = 0;
}

and this could be used as in:

LibraryFuncStruct myLib = {0};
LoadLibraryFunc (L"library.dll", &myLib);
//  ....
myLib.Func1();
//  ....
FreeLibraryFunc (&myLib);

The same approach can be used to define an abstract hardware layer for code that uses a particular model of the underlying hardware. Function pointers are filled in with hardware specific functions by a factory to provide the hardware specific functionality that implements functions specified in the abstract hardware model. This can be used to provide an abstract hardware layer used by software which calls a factory function in order to get the specific hardware function interface then uses the function pointers provided to perform actions for the underlying hardware without needing to know implementation details about the specific target.

Function Pointers to create Delegates, Handlers, and Callbacks

You can use function pointers as a way to delegate some task or functionality. The classic example in C is the comparison delegate function pointer used with the Standard C library functions qsort() and bsearch() to provide the collation order for sorting a list of items or performing a binary search over a sorted list of items. The comparison function delegate specifies the collation algorithm used in the sort or the binary search.

Another use is similar to applying an algorithm to a C++ Standard Template Library container.

void * ApplyAlgorithm (void *pArray, size_t sizeItem, size_t nItems, int (*p)(void *)) {
    unsigned char *pList = pArray;
    unsigned char *pListEnd = pList + nItems * sizeItem;
    for ( ; pList < pListEnd; pList += sizeItem) {
        p (pList);
    }

    return pArray;
}

int pIncrement(int *pI) {
    (*pI)++;

    return 1;
}

void * ApplyFold(void *pArray, size_t sizeItem, size_t nItems, void * pResult, int(*p)(void *, void *)) {
    unsigned char *pList = pArray;
    unsigned char *pListEnd = pList + nItems * sizeItem;
    for (; pList < pListEnd; pList += sizeItem) {
        p(pList, pResult);
    }

    return pArray;
}

int pSummation(int *pI, int *pSum) {
    (*pSum) += *pI;

    return 1;
}

// source code and then lets use our function.
int intList[30] = { 0 }, iSum = 0;

ApplyAlgorithm(intList, sizeof(int), sizeof(intList) / sizeof(intList[0]), pIncrement);
ApplyFold(intList, sizeof(int), sizeof(intList) / sizeof(intList[0]), &iSum, pSummation);

Another example is with GUI source code in which a handler for a particular event is registered by providing a function pointer which is actually called when the event happens. The Microsoft MFC framework with its message maps uses something similar to handle Windows messages that are delivered to a window or thread.

Asynchronous functions that require a callback are similar to an event handler. The user of the asynchronous function calls the asynchronous function to start some action and provides a function pointer which the asynchronous function will call once the action is complete. In this case the event is the asynchronous function completing its task.

' mouse pointer touch '.replace(/^\s+|\s+$|(\s)+/g, "$1") should do the trick!

2^128*1018 + 1 ( which is (2⁸)^16*1018 + 1 ) - cannot it be a universal answer for today? This represents a number that cannot be held in 16 EB file, which is the maximum file size in any current file system.

Two approaches:

1. Use Calendar and date(byAdding:to:wrappingComponents:). E.g., in Swift 3 and later:

   let calendar = Calendar.current
   let date = calendar.date(byAdding: .minute, value: 5, to: startDate)
   

2. Just use + operator (see +(_:_:)) to add a TimeInterval (i.e. a certain number of seconds). E.g. to add five minutes, you can:

   let date = startDate + 5 * 60
   

   (Note, the order is specific here: The date on the left side of the + and the seconds on the right side.)

   You can also use addingTimeInterval, if you’d prefer:

   let date = startDate.addingTimeInterval(5 * 60)
   

Bottom line, +/addingTimeInterval is easiest for simple scenarios, but if you ever want to add larger units (e.g., days, months, etc.), you would likely want to use the calendrical calculations because those adjust for daylight savings, whereas addingTimeInterval doesn’t.

For Swift 2 renditions, see the previous revision of this answer.

Go to xampp/php/php.ini

Find this line:

max_execution_time=30

And change its value to any number you want. Restart Apache.

You can use this.innerHTML.

<textarea name="message" rows = "10" cols = "100" onfocus="this.innerHTML=''"> Enter your message here... </textarea>

When text area is focused, it basically makes the innerHTML of the textarea an empty string.

this is my approach from a simple blog:

//Prime Numbers generation in C++
//Using for loops and conditional structures
#include <iostream>
using namespace std;

int main()
{
int a = 2;       //start from 2
long long int b = 1000;     //ends at 1000

for (int i = a; i <= b; i++)
{

 for (int j = 2; j <= i; j++)
 {
    if (!(i%j)&&(i!=j))    //Condition for not prime
        {
            break;
        }

    if (j==i)             //condition for Prime Numbers
        {
              cout << i << endl;

        }
 }
}
}

fyi, this can happen if you are using the html type="number" attribute on your input tag. Entering a non-number will clear it before your script knows what's going on.

From the MySQL manual

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas. Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

If you also want to set background position for your image, than you can use this:

background-color: #444; // fallback
background: url('PATH-TO-IMG') center center no-repeat; // fallback

background: url('PATH-TO-IMG') center center no-repeat, -moz-linear-gradient(top, @startColor, @endColor); // FF 3.6+
background: url('PATH-TO-IMG') center center no-repeat, -webkit-gradient(linear, 0 0, 0 100%, from(@startColor), to(@endColor)); // Safari 4+, Chrome 2+
background: url('PATH-TO-IMG') center center no-repeat, -webkit-linear-gradient(top, @startColor, @endColor); // Safari 5.1+, Chrome 10+
background: url('PATH-TO-IMG') center center no-repeat, -o-linear-gradient(top, @startColor, @endColor); // Opera 11.10
background: url('PATH-TO-IMG') center center no-repeat, linear-gradient(to bottom, @startColor, @endColor); // Standard, IE10

or you can also create a LESS mixin (bootstrap style):

#gradient {
    .vertical-with-image(@startColor: #555, @endColor: #333, @image) {
        background-color: mix(@startColor, @endColor, 60%); // fallback
        background-image: @image; // fallback

        background: @image, -moz-linear-gradient(top, @startColor, @endColor); // FF 3.6+
        background: @image, -webkit-gradient(linear, 0 0, 0 100%, from(@startColor), to(@endColor)); // Safari 4+, Chrome 2+
        background: @image, -webkit-linear-gradient(top, @startColor, @endColor); // Safari 5.1+, Chrome 10+
        background: @image, -o-linear-gradient(top, @startColor, @endColor); // Opera 11.10
        background: @image, linear-gradient(to bottom, @startColor, @endColor); // Standard, IE10
    }
}

In my case, it was because one test project in my solution had the MSTest.TestFramework and MSTest.TestAdapter nuget packages installed but the others did not. These packages were apparently not required to run tests until one project in the solution had them installed.

The issue was fixed by installing those packages on test projects missing them.

You can use the reinstall module found in npm.

After installing it, you can use the following command:

reinstall

The only difference with manually removing node_modules folder and making npm install is that this command automatically clear npm's cache. So, you can get three steps in one command.

upd: npx reinstall is a way to run this command without globally installing package (only for npm5+)

Not exactly with HTML5 validation but a little JavaScript can resolve the issue, follow the example below:

<p>Password:</p>
<input name="password" required="required" type="password" id="password" />
<p>Confirm Password:</p>
<input name="password_confirm" required="required" type="password" id="password_confirm" oninput="check(this)" />
<script language='javascript' type='text/javascript'>
    function check(input) {
        if (input.value != document.getElementById('password').value) {
            input.setCustomValidity('Password Must be Matching.');
        } else {
            // input is valid -- reset the error message
            input.setCustomValidity('');
        }
    }
</script>
<br /><br />
<input type="submit" />

I have a simple solution on handling home button press. Here is my code, it can be useful:

public class LifeCycleActivity extends Activity {


boolean activitySwitchFlag = false;

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) 
{
    if(keyCode == KeyEvent.KEYCODE_BACK)
    {
        activitySwitchFlag = true;
        // activity switch stuff..
        return true;
    }
    return false;
}

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

@Override 
public void onPause(){
    super.onPause();
    Log.v("TAG", "onPause" );
    if(activitySwitchFlag)
        Log.v("TAG", "activity switch");
    else
        Log.v("TAG", "home button");
    activitySwitchFlag = false;
}

public void gotoNext(View view){
    activitySwitchFlag = true;
    startActivity(new Intent(LifeCycleActivity.this, NextActivity.class));
}

}

As a summary, put a boolean in the activity, when activity switch occurs(startactivity event), set the variable and in onpause event check this variable..

It's simple as:

$('#action').val("1");

#action is hidden input field id.

declare @MyNumber int
set @MyNumber = 123
select 'My number is ' + CAST(@MyNumber as nvarchar(20))

Is it possible to list all of the possible goals (including, say, all the plugins) that it is possible to run?

Maven doesn't have anything built-in for that, although the list of phases is finite (the list of plugin goals isn't since the list of plugins isn't).

But you can make things easier and leverage the power of bash completion (using cygwin if you're under Windows) as described in the Guide to Maven 2.x auto completion using BASH (but before to choose the script from this guide, read further).

To get things working, first follow this guide to setup bash completion on your computer. Then, it's time to get a script for Maven2 and:

• While you could use the one from the mini guide
• While you use an improved version attached to MNG-3928
• While you could use a random scripts found around the net (see the resources if you're curious)
• I personally use the Bash Completion script from Ludovic Claude's PPA (which is bundled into the packaged version of maven in Ubuntu) that you can download from the HEAD. It's simply the best one.

Below, here is what I get just to illustrate the result:

$ mvn [tab][tab]
Display all 377 possibilities? (y or n)
ant:ant 
ant:clean 
ant:help 
antrun:help 
antrun:run 
archetype:crawl 
archetype:create 
archetype:create-from-project 
archetype:generate 
archetype:help 
assembly:assembly 
assembly:directory 
assembly:directory-single 
assembly:help 
assembly:single  
... 

Of course, I never browse the 377 possibilities, I use completion. But this gives you an idea about the size of "a" list :)

This error occurs because you tell to Maven to pakage files to war.

<packaging>war</packaging>

Do you really need war? If not, put jar there. Here is full code:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <version>1.0-SNAPSHOT</version>

    <groupId>com.your.groupid</groupId>
    <artifactId>artifactid</artifactId>
    <packaging>jar</packaging>

Edit the code to be as follows:

// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );

if( $moved ) {
  echo "Successfully uploaded";         
} else {
  echo "Not uploaded because of error #".$_FILES["file"]["error"];
}

It will give you one of the following error code values 1 to 8:

UPLOAD_ERR_INI_SIZE = Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.

UPLOAD_ERR_FORM_SIZE = Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.

UPLOAD_ERR_PARTIAL = Value: 3; The uploaded file was only partially uploaded.

UPLOAD_ERR_NO_FILE = Value: 4; No file was uploaded.

UPLOAD_ERR_NO_TMP_DIR = Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.

UPLOAD_ERR_CANT_WRITE = Value: 7; Failed to write file to disk. Introduced in PHP 5.1.0.

UPLOAD_ERR_EXTENSION = Value: 8; A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help.

Let's say that you have a folder named "contollers".

In your app.js you can put this code:

console.log("Loading controllers....");
var controllers = {};

var controllers_path = process.cwd() + '/controllers'

fs.readdirSync(controllers_path).forEach(function (file) {
    if (file.indexOf('.js') != -1) {
        controllers[file.split('.')[0]] = require(controllers_path + '/' + file)
    }
});

console.log("Controllers loaded..............[ok]");

... and ...

router.get('/ping', controllers.ping.pinging);

in your controllers forlder you will have the file "ping.js" with this code:

exports.pinging = function(req, res, next){
    console.log("ping ...");
}

And this is it....

For Firestore that is the new generation of database from Google, following code will simply help you through this problem.

var admin    = require("firebase-admin");

var serviceAccount = require("../admin-sdk.json"); // auto-generated file from Google firebase.

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount)
});
var db = admin.firestore();

console.log(admin.firestore.Timestamp.now().toDate());

i think android studio has a 64bit kernel version which is giving the problem. https://github.com/swcarpentry/windows-installer/issues/49

And in swift, you don't need to import "QuartzCore/QuartzCore.h"

Just use:

button.layer.borderWidth = 0.8
button.layer.borderColor = (UIColor( red: 0.5, green: 0.5, blue:0, alpha: 1.0 )).cgColor

or

button.layer.borderWidth = 0.8
button.layer.borderColor = UIColor.grayColor().cgColor

Do not assume your unix_socket which would be different from one to another, try to find it.

First of all, get your unix_socket location.

$ mysql -u root -p

Enter your mysql password and login your mysql server from command line.

mysql> show variables like '%sock%';
+---------------+---------------------------------------+
| Variable_name | Value                                 |
+---------------+---------------------------------------+
| socket        | /opt/local/var/run/mysql5/mysqld.sock |
+---------------+---------------------------------------+

Your unix_soket could be diffrent.

Then change your php.ini, find your php.ini file from

<? phpinfo();

You maybe install many php with different version, so please don't assume your php.ini file location, get it from your 'phpinfo';

Change your php.ini:

mysql.default_socket = /opt/local/var/run/mysql5/mysqld.sock

mysqli.default_socket = /opt/local/var/run/mysql5/mysqld.sock

pdo_mysql.default_socket = /opt/local/var/run/mysql5/mysqld.sock

Then restart your apache or php-fpm.

I had two significant errors in my program. From the other answers, I learned in a single java program, one can not declare two classes as "public". So I changed the access specifier, but got another error as added to my question as "EDIT" that "Selection does not contain a main type". Finally I observed I forgot to add "String args[]" part in my main method. That's why the code was not working. After rectification, it worked as expected.

These issue arise generally due to mismatch between @ngx-translate/core version and Angular .Before installing check compatible version of corresponding ngx_trnalsate/Core, @ngx-translate/http-loader and Angular at https://www.npmjs.com/package/@ngx-translate/core

Eg: For Angular 6.X versions,

npm install @ngx-translate/core@10 @ngx-translate/http-loader@3 rxjs --save

Like as above, follow below command and rest of code part is common for all versions(Note: Version can obtain from( https://www.npmjs.com/package/@ngx-translate/core)

npm install @ngx-translate/core@version @ngx-translate/http-loader@version rxjs --save

@HostListener('window:click', ['$event']) onClick(event){ }

check this below link to detect CapsLock on click, keyup and keydown on current window. No need to add any event in html doc

Detect and warn users about caps lock is on

This is due to a bug in Webkit.

You can work around the Webkit bug using createEvent('Event') rather than createEvent('KeyboardEvent'), and then assigning the keyCode property. See this answer and this example.

I know I am too late to answer this question. I am not sure does my method still working on low iOS versions (< 5.0):

NSString *platform = [UIDevice currentDevice].model;

NSLog(@"[UIDevice currentDevice].model: %@",platform);
NSLog(@"[UIDevice currentDevice].description: %@",[UIDevice currentDevice].description);
NSLog(@"[UIDevice currentDevice].localizedModel: %@",[UIDevice currentDevice].localizedModel);
NSLog(@"[UIDevice currentDevice].name: %@",[UIDevice currentDevice].name);
NSLog(@"[UIDevice currentDevice].systemVersion: %@",[UIDevice currentDevice].systemVersion);
NSLog(@"[UIDevice currentDevice].systemName: %@",[UIDevice currentDevice].systemName);

You can get these results:

[UIDevice currentDevice].model: iPhone
[UIDevice currentDevice].description: <UIDevice: 0x1cd75c70>
[UIDevice currentDevice].localizedModel: iPhone
[UIDevice currentDevice].name: Someones-iPhone002
[UIDevice currentDevice].systemVersion: 6.1.3
[UIDevice currentDevice].systemName: iPhone OS

The problem I was having, which I think is similar to this, is that master was too far ahead of my branch point for the history to be useful. (Navigating to the branch point would take too long.)

After some trial and error, this gave me roughly what I wanted:

git log --graph --decorate --oneline --all ^master^!

Well, if you have Visual Studio (I know it's in 2005, not sure about earlier versions though), you can add the remote machine to your "Server Explorer" tag. At that point, you'll have access to the SERVICES that are running, or can be ran, from that machine (as well as event logs, and queues, and a couple other interesting things).

The PowerShell is almost exactly the same.

$webclient = new-object System.Net.WebClient
$webclient.Credentials = new-object System.Net.NetworkCredential($username, $password, $domain)
$webpage = $webclient.DownloadString($url)

1. Ensure that you have your Dbms Output window open through the view option in the menubar.
2. Click on the green '+' sign and add your database name.
3. Write 'DBMS_OUTPUT.ENABLE;' within your procedure as the first line. Hope this solves your problem.

I've written a script to get all child process pids of a parent process. Here is the code. Hope it will help.

function getcpid() {
    cpids=`pgrep -P $1|xargs`
#    echo "cpids=$cpids"
    for cpid in $cpids;
    do
        echo "$cpid"
        getcpid $cpid
    done
}

getcpid $1

Here is an edited version of your code which is based on ISO C++ and which works well with G++:

#include <string.h>
#include <iostream>
using namespace std;

#define NO_OF_TEST 1

struct studentType {
    string studentID;
    string firstName;
    string lastName;
    string subjectName;
    string courseGrade;
    int arrayMarks[4];
    double avgMarks;
};

studentType input() {
    studentType newStudent;
    cout << "\nPlease enter student information:\n";

    cout << "\nFirst Name: ";
    cin >> newStudent.firstName;

    cout << "\nLast Name: ";
    cin >> newStudent.lastName;

    cout << "\nStudent ID: ";
    cin >> newStudent.studentID;

    cout << "\nSubject Name: ";
    cin >> newStudent.subjectName;

    for (int i = 0; i < NO_OF_TEST; i++) {
        cout << "\nTest " << i+1 << " mark: ";
        cin >> newStudent.arrayMarks[i];
    }

    return newStudent;
}

int main() {
    studentType s;
    s = input();

    cout <<"\n========"<< endl << "Collected the details of "
        << s.firstName << endl;

    return 0;
}

You will need to Build and Archive your project. You may need to check what code signing settings you have in the project and executable.

Use the Organiser to select your archive version and then you can Share that version of your project. You will need to select the correct code signing again. It will allow you to save the .ipa file where you want.

Drag and drop the .ipa file into iTunes and then sync with your iPhone.

I wouldn't recommend OpenPOP. I just spent a few hours debugging an issue - OpenPOP's POPClient.GetMessage() was mysteriously returning null. I debugged this and found it was a string index bug - see the patch I submitted here: http://sourceforge.net/tracker/?func=detail&aid=2833334&group_id=92166&atid=599778. It was difficult to find the cause since there are empty catch{} blocks that swallow exceptions.

Also, the project is mostly dormant... the last release was in 2004.

For now we're still using OpenPOP, but I'll take a look at some of the other projects people have recommended here.

this query return last record for every Form_id:

    SELECT m1.*
     FROM messages m1 LEFT JOIN messages m2
     ON (m1.Form_id = m2.Form_id AND m1.id < m2.id)
     WHERE m2.id IS NULL;

Using == might be dangerous.

Note, that it would cast the variable to another data type if the two differs.

Examples:

• echo (1 == '1') ? 'true' : 'false';
• echo (1 == true) ? 'true' : 'false';

As you can see, these two are from different types, but the result is true, which might not be what your code will expect.

Using ===, however, is recommended as test shows that it's a bit faster than strcmp() and its case-insensitive alternative strcasecmp().

Quick googling yells this speed comparison: http://snipplr.com/view/758/

You can use this simple code below.

Code: DateTime.Now.ToShortDateString();

Ex. Console.WriteLine(DateTime.Now.ToShortDateString());

This is the algorithm using stack.
Just follow these simple steps.

1.Reverse the given infix expression.

2.Replace '(' with ')' and ')' with '(' in the reversed expression.

3.Now apply standard infix to postfix subroutine.

4.Reverse the founded postfix expression, this will give required prefix expression.

In case you find step 3 difficult consult http://scanftree.com/Data_Structure/infix-to-prefix where a worked out example is also given.

try this query below:

Insert into tab1 (tab1.column1,tab1.column2) 
select tab2.column1, 'hard coded  value' 
from tab2 
where tab2.column='value';

SELECT column1 FROM table WHERE column1 not like '%[0-9]%'

Removing the '^' did it for me. I'm looking at a varchar field and when I included the ^ it excluded all of my non-numerics which is exactly what I didn't want. So, by removing ^ I only got non-numeric values back.

After placing the jar file in desired location, you need to add the jar file by right click on

Project --> properties --> Java Build Path --> Libraries --> Add Jar.

(For Childs Route Only such as /hello-world)

In the case you would like to make this kind of call :

/hello-world?foo=bar&fruit=banana

Angular2 doesn't use ? nor & but ; instead. So the correct URL should be :

/hello-world;foo=bar;fruit=banana

And to get those data :

import { Router, ActivatedRoute, Params } from '@angular/router';

private foo: string;
private fruit: string;

constructor(
  private route: ActivatedRoute,
  private router: Router
  ) {}

ngOnInit() {
  this.route.params.forEach((params: Params) => {
      this.foo = params['foo'];
      this.fruit = params['fruit'];
  });
  console.log(this.foo, this.fruit); // you should get your parameters here
}

That is the timeout to create the connection, NOT a timeout for commands executed over that connection.

See for instance http://www.connectionstrings.com/all-sql-server-connection-string-keywords/ (note that the property is "Connect Timeout" (or "Connection Timeout"), not just "Timeout")

From the comments:

It is not possible to set the command timeout through the connection string. However, the SqlCommand has a CommandTimeout property (derived from DbCommand) where you can set a timeout (in seconds) per command.

Do note that when you loop over query results with Read(), the timeout is reset on every read. The timeout is for each network request, not for the total connection.

Raw HTML is actually perfectly valid in markdown. For instance:

Normal *markdown* paragraph.

<p class="myclass">This paragraph has a class "myclass"</p>

Just make sure the HTML is not inside a code block.

In some devices void onConfigurationChanged() may crash. User will use this code to get current screen orientation.

public int getScreenOrientation()
{
    Display getOrient = getActivity().getWindowManager().getDefaultDisplay();
    int orientation = Configuration.ORIENTATION_UNDEFINED;
    if(getOrient.getWidth()==getOrient.getHeight()){
        orientation = Configuration.ORIENTATION_SQUARE;
    } else{ 
        if(getOrient.getWidth() < getOrient.getHeight()){
            orientation = Configuration.ORIENTATION_PORTRAIT;
        }else { 
             orientation = Configuration.ORIENTATION_LANDSCAPE;
        }
    }
    return orientation;
}

And use

if (orientation==1)        // 1 for Configuration.ORIENTATION_PORTRAIT
{                          // 2 for Configuration.ORIENTATION_LANDSCAPE
   //your code             // 0 for Configuration.ORIENTATION_SQUARE
}

In the newer version of Hadoop, there are much more granular mapreduce.job.running.map.limit and mapreduce.job.running.reduce.limit which allows you to set the mapper and reducer count irrespective of hdfs file split size. This is helpful if you are under constraint to not take up large resources in the cluster.

JIRA

Yes, it a vice versa. It depends on which side of the relationship the entity is present on.

For example, if one department can employ for several employees then, department to employee is a one to many relationship (1 department employs many employees), while employee to department relationship is many to one (many employees work in one department).

More info on the relationship types:

Database Relationships - IBM DB2 documentation

Make sure the folder you have created inside htdocs are present there and you browse the right url.

for example

localhost/yoursitename

make sure yoursitename folder is present

You could try an "onclick" event inside the LI tag, and change the "location.href" as in javascript.

You could also try placing the li tags within the a tags, however this is probably not valid HTML.

Got this problem while transforming my old code from XCode 3x to XCode 4 and Solved it by just renaming wwwwwwww.xib into RootViewController.xib

To stay with a specific major release, activate the AdoptOpenJDK tap with brew tap and then install the desired version with brew cask install:

$ brew tap AdoptOpenJDK/openjdk
$ brew cask install <version>

To install AdoptOpenJDK 14 with HotSpot, run:

$ brew tap AdoptOpenJDK/openjdk
$ brew cask install adoptopenjdk14

this may be old, but for those looking for answer you can use this...

public void stopHandler() {
   handler.removeMessages(0);
}

cheers

In order to completely override the bootstrap button styles, you need to override a list of properties. See the below example.

    .btn-primary, .btn-primary:hover, .btn-primary:focus, .btn-primary.focus, 
    .btn-primary:active, .btn-primary.active, .btn-primary:visited,
    .btn-primary:active:hover, .btn-primary.active:hover{
        background-color: #F19425;
        color:#fff;
        border: none;
        outline: none;
    }

If you don't use all the listed styles then you will see the default styles at performing actions on button. For example once you click the button and remove mouse pointer from button, you will see the default color visible. Or keep the button pressed you will see default colors. So, I have listed all the pseudo-styles that are to be overridden.

I had the same issue in a Windows Service. All keys where in the right place in the registry. The build of the service was done for x86 and I still got the exception. I found out about CorFlags.exe

Run this on your service.exe without flags to verify if you run under 32 bit. If not run it with the flag /32BIT+ /Force (Force only for signed assemblies)

If you have UAC turned you can get the following error: corflags : error CF001 : Could not open file for writing Give the user full control on the assemblies.

Or this beautiful round progress bar with HTML5, CSS3 and JavaScript.

I figured out how to do this. I was building an application very similar to the example/tutorial you discussed in your original question.

Here's a snippet of the code that worked for me:

        int pageSize = 4;
        int pageNumber = (page ?? 1);
        //Used the following two formulas so that it doesn't round down on the returned integer
        decimal totalPages = ((decimal)(viewModel.Teachers.Count() /(decimal) pageSize));     
        ViewBag.TotalPages = Math.Ceiling(totalPages);  
        //These next two functions could maybe be reduced to one function....would require some testing and building
        viewModel.Teachers = viewModel.Teachers.ToPagedList(pageNumber, pageSize);
        ViewBag.OnePageofTeachers = viewModel.Teachers;
        ViewBag.PageNumber = pageNumber;

        return View(viewModel);

I added

using.PagedList;

to my controller as the tutorial states.

Now in my view my using statements etc at the top, NOTE i didnt change my using model statement.

@model CSHM.ViewModels.TeacherIndexData
@using PagedList;
@using PagedList.Mvc;
<link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />

and then at the bottom to build my paged list I used the following and it seems to work. I haven't yet built in the functionality for current sort, showing related data, filters, etc but i dont think it will be that difficult.

Page @ViewBag.PageNumber of @ViewBag.TotalPages

@Html.PagedListPager((IPagedList)ViewBag.OnePageofTeachers, page => Url.Action("Index", new { page }))

Hope that works for you. Let me know if it works!!

I would like to make a addon for tiago's answer:

Suppose you're hiding element using ng-show and adding a required attribute on the same:

<div ng-show="false">
    <input required name="something" ng-model="name"/>
</div>

will throw an error something like :

An invalid form control with name='' is not focusable

This is because you just cannot impose required validation on hidden elements. Using ng-required makes it easier to conditionally apply required validation which is just awesome!!

You were right regarding how you want to generate salt i.e. its nothing but a random number. For this particular case it would protect your system from possible Dictionary attacks. Now, for the second problem what you could do is instead of using UTF-8 encoding you may want to use Base64. Here, is a sample for generating a hash. I am using Apache Common Codecs for doing the base64 encoding you may select one of your own

public byte[] generateSalt() {
        SecureRandom random = new SecureRandom();
        byte bytes[] = new byte[20];
        random.nextBytes(bytes);
        return bytes;
    }

public String bytetoString(byte[] input) {
        return org.apache.commons.codec.binary.Base64.encodeBase64String(input);
    }

public byte[] getHashWithSalt(String input, HashingTechqniue technique, byte[] salt) throws NoSuchAlgorithmException {
        MessageDigest digest = MessageDigest.getInstance(technique.value);
        digest.reset();
        digest.update(salt);
        byte[] hashedBytes = digest.digest(stringToByte(input));
        return hashedBytes;
    }
public byte[] stringToByte(String input) {
        if (Base64.isBase64(input)) {
            return Base64.decodeBase64(input);

        } else {
            return Base64.encodeBase64(input.getBytes());
        }
    }

Here is some additional reference of the standard practice in password hashing directly from OWASP

You have a pointer to an object. Therefore, you need to access a field of an object that's pointed to by the pointer. To dereference the pointer you use *, and to access a field, you use ., so you can use:

cout << (*kwadrat).val1;

Note that the parentheses are necessary. This operation is common enough that long ago (when C was young) they decided to create a "shorthand" method of doing it:

cout << kwadrat->val1;

These are defined to be identical. As you can see, the -> basically just combines a * and a . into a single operation. If you were dealing directly with an object or a reference to an object, you'd be able to use the . without dereferencing a pointer first:

Kwadrat kwadrat2(2,3,4);

cout << kwadrat2.val1;

The :: is the scope resolution operator. It is used when you only need to qualify the name, but you're not dealing with an individual object at all. This would be primarily to access a static data member:

struct something { 
    static int x; // this only declares `something::x`. Often found in a header
};

int something::x;  // this defines `something::x`. Usually in .cpp/.cc/.C file.

In this case, since x is static, it's not associated with any particular instance of something. In fact, it will exist even if no instance of that type of object has been created. In this case, we can access it with the scope resolution operator:

something::x = 10;

std::cout << something::x;

Note, however, that it's also permitted to access a static member as if it was a member of a particular object:

something s;

s.x = 1;

At least if memory serves, early in the history of C++ this wasn't allowed, but the meaning is unambiguous, so they decided to allow it.

We have similar situation right now and as of this answer, I am using laravel 5.6 release.

I will not use your example in the question but mine, because it's related though.

I have route like this:

Route::name('your.name.here')->get('/your/uri', 'YourController@someMethod');

Then in your controller method, make sure you include

use Illuminate\Http\Request;

and this should be above your controller, most likely a default, if generated using php artisan, now to get variable from the url it should look like this:

  public function someMethod(Request $request)
  {
    $foo = $request->input("start");
    $bar = $request->input("limit");

    // some codes here
  }

Regardless of the HTTP verb, the input() method may be used to retrieve user input.

https://laravel.com/docs/5.6/requests#retrieving-input

Hope this help.

this can help to evaluate http status

var=`curl -I http://www.example.org 2>/dev/null | head -n 1 | awk -F" " '{print $2}'`
echo http:$var

As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.

Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :

> x <- factor(sample(4:8,10,replace=T))
> x
 [1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
 [1] 6 4 8 6 7 6 8 5 8 4

To show it works.

The timings :

> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
   user  system elapsed 
   0.11    0.00    0.11 
> system.time(as.numeric(levels(x))[x])
   user  system elapsed 
      0       0       0 

It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.

There are many way you can do this. Those are given bellow:

Suppose your original number is given bellow: double number = 2354548.235;

Using NumberFormat and Rounding mode

NumberFormat nf = DecimalFormat.getInstance(Locale.ENGLISH);
    DecimalFormat decimalFormatter = (DecimalFormat) nf;
    decimalFormatter.applyPattern("#,###,###.##");
    decimalFormatter.setRoundingMode(RoundingMode.CEILING);

    String fString = decimalFormatter.format(number);
    System.out.println(fString);

Using String formatter

System.out.println(String.format("%1$,.2f", number));

In all cases the output will be: 2354548.24

Note:

During rounding you can add RoundingMode in your formatter. Here are some Rounding mode given bellow:

    decimalFormat.setRoundingMode(RoundingMode.CEILING);
    decimalFormat.setRoundingMode(RoundingMode.FLOOR);
    decimalFormat.setRoundingMode(RoundingMode.HALF_DOWN);
    decimalFormat.setRoundingMode(RoundingMode.HALF_UP);
    decimalFormat.setRoundingMode(RoundingMode.UP);

Here are the imports:

import java.math.BigDecimal;
import java.math.RoundingMode;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Locale;

For me what worked by combining all the posts I have read is:

1.Enable OLE automation - if not enabled

sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE;  
GO  
sp_configure 'Ole Automation Procedures', 1;  
GO  
RECONFIGURE;  
GO

2.Create a folder where the generated files will be stored:

C:\GREGTESTING

3.Create DocTable that will be used for file generation and store there the blobs in Doc_Content

CREATE TABLE [dbo].[Document](
    [Doc_Num] [numeric](18, 0) IDENTITY(1,1) NOT NULL,
    [Extension] [varchar](50) NULL,
    [FileName] [varchar](200) NULL,
    [Doc_Content] [varbinary](max) NULL   
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 

INSERT [dbo].[Document] ([Extension] ,[FileName] , [Doc_Content] )
    SELECT 'pdf', 'SHTP Notional hire - January 2019.pdf', 0x....(varbinary blob)

Important note!

Don't forget to add in Doc_Content column the varbinary of file you want to generate!

4.Run the below script

DECLARE @outPutPath varchar(50) = 'C:\GREGTESTING'
, @i bigint
, @init int
, @data varbinary(max) 
, @fPath varchar(max)  
, @folderPath  varchar(max)

--Get Data into temp Table variable so that we can iterate over it 
DECLARE @Doctable TABLE (id int identity(1,1), [Doc_Num]  varchar(100) , [FileName]  varchar(100), [Doc_Content] varBinary(max) )



INSERT INTO @Doctable([Doc_Num] , [FileName],[Doc_Content])
Select [Doc_Num] , [FileName],[Doc_Content] FROM  [dbo].[Document]



SELECT @i = COUNT(1) FROM @Doctable   

WHILE @i >= 1   

BEGIN    

SELECT 
    @data = [Doc_Content],
    @fPath = @outPutPath + '\' + [Doc_Num] +'_' +[FileName],
    @folderPath = @outPutPath + '\'+ [Doc_Num]
FROM @Doctable WHERE id = @i

EXEC sp_OACreate 'ADODB.Stream', @init OUTPUT; -- An instace created
EXEC sp_OASetProperty @init, 'Type', 1;  
EXEC sp_OAMethod @init, 'Open'; -- Calling a method
EXEC sp_OAMethod @init, 'Write', NULL, @data; -- Calling a method
EXEC sp_OAMethod @init, 'SaveToFile', NULL, @fPath, 2; -- Calling a method
EXEC sp_OAMethod @init, 'Close'; -- Calling a method
EXEC sp_OADestroy @init; -- Closed the resources
print 'Document Generated at - '+  @fPath   

--Reset the variables for next use
SELECT @data = NULL  
, @init = NULL
, @fPath = NULL  
, @folderPath = NULL
SET @i -= 1
END   

5.The results is shown below:

Activation by system properties can be done as follows

<activation>
    <property>
        <name>foo</name>
        <value>bar</value>
    </property>
</activation>

And run the mvn build with -D to set system property

mvn clean install -Dfoo=bar

This method also helps select profiles in transitive dependency of project artifacts.

Dont forget to add user agent since some server will block request if there's no server agent..(you would get Forbidden resource response) example :

curl -X POST -A 'Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0' -d "field=acaca&name=afadxx" https://example.com
