The Request.Files collection contains any files uploaded with your form, regardless of whether they came from a FileUpload control or a manually written <input type="file">.

So you can just write a plain old file input tag in the middle of your WebForm, and then read the file uploaded from the Request.Files collection.

Use Server.HtmlDecode to decode the HTML entities. If you want to escape the HTML, i.e. display the < and > character to the user, use Server.HtmlEncode.

For example here is a element like button for adding item to basket and appropriate attributes for saving in localStorage.

'<a href="#" cartBtn pr_id='+e.id+' pr_name_en="'+e.nameEn+'" pr_price="'+e.price+'" pr_image="'+e.image+'" class="btn btn-primary"><i class="fa fa-shopping-cart"></i>Add to cart</a>'

var productArray=[];


$(document).on('click','[cartBtn]',function(e){
  e.preventDefault();
  $(this).html('<i class="fa fa-check"></i>Added to cart');
  console.log('Item added ');
  var productJSON={"id":$(this).attr('pr_id'), "nameEn":$(this).attr('pr_name_en'), "price":$(this).attr('pr_price'), "image":$(this).attr('pr_image')};


  if(localStorage.getObj('product')!==null){
    productArray=localStorage.getObj('product');
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }
  else{
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }


});

Storage.prototype.setObj = function(key, value) {
    this.setItem(key, JSON.stringify(value));
}

Storage.prototype.getObj = function(key) {
    var value = this.getItem(key);
    return value && JSON.parse(value);
}

After adding JSON object to Array result is (in LocalStorage):

[{"id":"99","nameEn":"Product Name1","price":"767","image":"1462012597217.jpeg"},{"id":"93","nameEn":"Product Name2","price":"76","image":"1461449637106.jpeg"},{"id":"94","nameEn":"Product Name3","price":"87","image":"1461449679506.jpeg"}]

after this action you can easily send data to server as List in Java

Full code example is here

How do I store a simple cart using localStorage?

There are three ways of defining things in Scala:

• def defines a method
• val defines a fixed value (which cannot be modified)
• var defines a variable (which can be modified)

Looking at your code:

def person = new Person("Kumar",12)

This defines a new method called person. You can call this method only without () because it is defined as parameterless method. For empty-paren method, you can call it with or without '()'. If you simply write:

person

then you are calling this method (and if you don't assign the return value, it will just be discarded). In this line of code:

person.age = 20

what happens is that you first call the person method, and on the return value (an instance of class Person) you are changing the age member variable.

And the last line:

println(person.age)

Here you are again calling the person method, which returns a new instance of class Person (with age set to 12). It's the same as this:

println(person().age)

Lambdaj allows to do that in a very simple and readable way. For example, supposing you have a list of Integer and you want to convert them in the corresponding String representation you could write something like that;

List<Integer> ints = asList(1, 2, 3, 4);
Iterator<String> stringIterator = convertIterator(ints, new Converter<Integer, String> {
    public String convert(Integer i) { return Integer.toString(i); }
}

Lambdaj applies the conversion function only while you're iterating on the result.

What is a file with extension .sh?

It is a Bourne shell script. They are used in many variations of UNIX-like operating systems. They have no "language" and are interpreted by your shell (interpreter of terminal commands) or if the first line is in the form

#!/path/to/interpreter

they will use that particular interpreter. Your file has the first line:

#!/bin/bash

and that means that it uses Bourne Again Shell, so called bash. It is for all practical purposes a replacement for good old sh.

Depending upon the interpreter you will have different language in which the file is written.

Keep in mind, that in UNIX world, it is not the extension of the file that determines what the file is (see How to execute a shell script).

If you come from the world of DOS/Windows, you will be familiar with files that have .bat or .cmd extensions (batch files). They are not similar in content, but are akin in design.

How to execute a shell script

Unlike some silly operating systems, *nix does not rely exclusively on extensions to determine what to do with a file. Permissions are also used. This means that if you attempt to run the shell script after downloading it, it will be the same as trying to "run" any text file. The ".sh" extension is there only for your convenience to recognize that file.

You will need to make the file executable. Let's assume that you have downloaded your file as file.sh, you can then run in your terminal:

chmod +x file.sh

chmod is a command for changing file's permissions, +x sets execute permissions (in this case for everybody) and finally you have your file name.

You can also do it in GUI. Most of the time you can right click on the file and select properties, in XUbuntu the permissions options look like this:

If you do not wish to change the permissions. You can also force the shell to run the command. In the terminal you can run:

bash file.sh

The shell should be the same as in the first line of your script.

How safe is it?

You may find it weird that you must perform another task manually in order to execute a file. But this is partially because of strong need for security.

Basically when you download and run a bash script, it is the same thing as somebody telling you "run all these commands in sequence on your computer, I promise that the results will be good and safe". Ask yourself if you trust the party that has supplied this file, ask yourself if you are sure that have downloaded the file from the same place as you thought, maybe even have a glance inside to see if something looks out of place (although that requires that you know something about *nix commands and bash programming).

Unfortunately apart from the warning above I cannot give a step-by-step description of what you should do to prevent evil things from happening with your computer; so just keep in mind that any time you get and run an executable file from someone you're actually saying, "Sure, you can use my computer to do something".

Make sure that in the path to the project there is no foldername having whitespace. While creating a project the specified path folders must not contain any space in their naming.

You can use an extension method.

public static class Extensions
{

    public static T ToEnum<T>(this string data) where T : struct
    {
        if (!Enum.TryParse(data, true, out T enumVariable))
        {
            if (Enum.IsDefined(typeof(T), enumVariable))
            {
                return enumVariable;
            }
        }

        return default;
    }

    public static T ToEnum<T>(this int data) where T : struct
    {
        return (T)Enum.ToObject(typeof(T), data);
    }
}

Use it like the below code:

Enum:

public enum DaysOfWeeks
{
    Monday = 1,
    Tuesday = 2,
    Wednesday = 3,
    Thursday = 4,
    Friday = 5,
    Saturday = 6,
    Sunday = 7,
}

Usage:

 string Monday = "Mon";
 int Wednesday = 3;
 var Mon = Monday.ToEnum<DaysOfWeeks>();
 var Wed = Wednesday.ToEnum<DaysOfWeeks>();

I just saw another question very similar to this!

Here is the canonical NORTHWIND (spelled just slightly different for some reason) database example.

SELECT *
FROM [NORTHWND].[dbo].[Products]

SELECT CategoryId,
           MAX( CASE seq WHEN 1 THEN ProductName ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 2 THEN ProductName ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 3 THEN ProductName ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 4 THEN ProductName ELSE '' END )
      FROM ( SELECT p1.CategoryId, p1.ProductName,
                    ( SELECT COUNT(*) 
                        FROM NORTHWND.dbo.Products p2
                        WHERE p2.CategoryId = p1.CategoryId
                        AND p2.ProductName <= p1.ProductName )
             FROM NORTHWND.dbo.Products p1 ) D ( CategoryId, ProductName, seq )
     GROUP BY CategoryId ;

One Way to solve this problem is, push the negative of each element in the priority_queue so the largest element will become the smallest element. At the time of making pop operation, take the negation of each element.

#include<bits/stdc++.h>
using namespace std;

int main(){
    priority_queue<int> pq;
    int i;

// push the negative of each element in priority_queue, so the largest number will become the smallest number

    for (int i = 0; i < 5; i++)
    {
        cin>>j;
        pq.push(j*-1);
    }

    for (int i = 0; i < 5; i++)
    {
        cout<<(-1)*pq.top()<<endl;
        pq.pop();
    }
}

Using implode(), you can turn the array into a string.

$str = implode(',', $array); // 33160,33280,33180,...

In order to ssh to a Ubuntu VM running in VirtualBox from your host machine, you need to set up two network adapters for the VM.

First of all, stop the VM if not yet.

Then select the VM and click the Settings menu in the VirtualBox toolbar:

Set up Adapter 1

Set up Adapter 2

(Note: you don't need to set up any port forwarding.)

That's it. Once set up, you can start your VM. In your VM, the network configuration will look like below and you'll have Internet access too:

Also in your host machine, you can ssh to your VM:

Be sure that the SSH server has been installed and up running in the VM.

$ ps aux | grep sshd
root 864 0.1 0.5 65512 5392 ? Ss 22:10 0:00 /usr/sbin/sshd -D

If not, install it:

$ sudo apt-get install openssh-server

Also for your information:

• My VirtualBox version: 5.2.6 r120293 (Qt5.6.2), 2018
• My Ubuntu version: Ubuntu 16.04.3 LTS
• My host machine: Windows 10

I would like to extend wkw answer:

Simply adding only footer with height 0 will do the trick. (tested on sdk 4.2, 4.4.1)

- (void) addFooter
{
    UIView *v = [[UIView alloc] initWithFrame:CGRectZero];

    [self.myTableView setTableFooterView:v];
}

or even simpler - where you set up your tableview, add this line:

//change height value if extra space is needed at the bottom.
[_tableView setTableFooterView:[[UIView alloc] initWithFrame:CGRectMake(0,0,0,0)]];

or even simplier - to simply remove any separators:

[_tableView setTableFooterView:[UIView new]];

Thanks to wkw again :)

Your declaration is int ttTreeInsert(int value);

However, your definition/implementation is

ttTree::ttTreeInsert(int value)
{
}

Notice that the return type int is missing in the implementation. Instead it should be

int ttTree::ttTreeInsert(int value)
{
    return 1; // or some valid int
}

Pseudo code, something like:

CASE
  When CHARINDEX('lactulose', dbo.Table.Column) > 0 Then 'BP Medication'
ELSE ''
END AS 'Medication Type'

This does not care where the keyword is found in the list and avoids depending on formatting of spaces and commas.

In the CMakeLists.txt file, create a cache variable, as documented here:

SET(FAB "po" CACHE STRING "Some user-specified option")

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#command:set

Then, either use the GUI (ccmake or cmake-gui) to set the cache variable, or specify the value of the variable on the cmake command line:

cmake -DFAB:STRING=po

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#opt:-Dvar:typevalue

Modify your cache variable to a boolean if, in fact, your option is boolean.

You are looking for np.matmul(X, y). In Python 3.5+ you can use X @ y.

Count(distinct({fieldname})) is redundant

Simply Count({fieldname}) gives you all the distinct values in that table. It will not (as many presume) just give you the Count of the table [i.e. NOT the same as Count(*) from table]

The most condensed version:

public String getNameFromURI(Uri uri) {
    Cursor c = getContentResolver().query(uri, null, null, null, null);
    c.moveToFirst();
    return c.getString(c.getColumnIndex(OpenableColumns.DISPLAY_NAME));
}

For me the only thing that worked is inline css + overriding

<i class="fas fa-ellipsis-v fa-2x" style="color:red !important"></i>

/**

 *
 * @param string $url URL.
 * @param array $post_data POST data. Example: array('foo' => 'var', 'id' => 123)
 * @param array $headers Optional. Extra headers to send.
 */
public function redirect_post($url, array $data, array $headers = null) {
    $params = array(
        'http' => array(
            'method' => 'POST',
            'content' => http_build_query($data)
        )
    );
    if (!is_null($headers)) {
        $params['http']['header'] = '';
        foreach ($headers as $k => $v) {
            $params['http']['header'] .= "$k: $v\n";
        }
    }
    $ctx = stream_context_create($params);
    $fp = @fopen($url, 'rb', false, $ctx);
    if ($fp) {
        echo @stream_get_contents($fp);
        die();
    } else {
        // Error
        throw new Exception("Error loading '$url', $php_errormsg");
    }
}

Another alternative to those mentioned if you need to do this a bunch of times with the same migration(s). Personally I think this adds a lot of flexibility to your migrations.

Add database/migrations to your autoload object in your composer.json like this:

"autoload": {
        "psr-4": {
            "App\\": "app/"
        },
        "classmap": [
            "database/seeds",
            "database/factories",
            "database/support",
            "database/migrations" // add this line
        ]
    },

Then add namespace Database\Migrations; to all of your migration files.

Then run $ composer dump-autoload to refresh your composer.lock file.

Then, assuming your class name for the migration is AlterTableWebDirectories, you can create a command like this:

$ php artisan make:command DropAlterTableWebDirectories

And write this logic in your handle() method:

public function handle {
   (new AlterTableWebDirectories)->down();
   DB::raw("delete from migrations where migration like '%alter_table_web_directories%'");
}

This will do exactly what you want. If you want to decrement the migration count instead of deleting it, you can probably figure out how to change the DB:raw command.

This command could be extended to allow you to dynamically choose which migration you're dropping it by passing an argument into the command.

Then when you're reading to migrate that file again, you can just run php artisan migrate and it will only migrate that one.

This process allows you to make specific changes to migrations without having to do a full refresh and seed each time.

Personally I need to do that a lot because my seeds are rather large.

Wrap the code in document ready and prevent the default submit action:

$(function() { //shorthand document.ready function
    $('#login_form').on('submit', function(e) { //use on if jQuery 1.7+
        e.preventDefault();  //prevent form from submitting
        var data = $("#login_form :input").serializeArray();
        console.log(data); //use the console for debugging, F12 in Chrome, not alerts
    });
});

This worked for me:

grep ".*${expr}" - with double-quotes, preceded by the dot. Where "expr" is whatever string you need in the end of the line.

Standard unix grep w/out additional switches.

In the newer versions of Handlebars index (or key in the case of object iteration) is provided by default with the standard each helper.

snippet from : https://github.com/wycats/handlebars.js/issues/250#issuecomment-9514811

The index of the current array item has been available for some time now via @index:

{{#each array}}
    {{@index}}: {{this}}
{{/each}}

For object iteration, use @key instead:

{{#each object}}
    {{@key}}: {{this}}
{{/each}} 

Assume a dataframe with 19 rows

index=range(0,19)
index

columns=['A']
test = pd.DataFrame(index=index, columns=columns)

Keeping Column A as a constant

test['A']=10

Keeping column b as a variable given by a loop

for x in range(0,19):
    test.loc[[x], 'b'] = pd.Series([x], index = [x])

You can replace the first x in pd.Series([x], index = [x]) with any value

Baud rate is mostly used in telecommunication and electronics, representing symbol per second or pulses per second, whereas bit rate is simply bit per second. To be simple, the major difference is that symbol may contain more than 1 bit, say n bits, which makes baud rate n times smaller than bit rate.

Suppose a situation where we need to represent a serial-communication signal, we will use 8-bit as one symbol to represent the info. If the symbol rate is 4800 baud, then that translates into an overall bit rate of 38400 bits/s. This could also be true for wireless communication area where you will need multiple bits for purpose of modulation to achieve broadband transmission, instead of simple baseline transmission.

Hope this helps.

I had this error today and discovered it was an incorrectly-formatted year...

select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')

Notice the year has only three 'y's. It should have 4.

Double-check your format.

Inside config folder open app.php

Change

'debug' => false,

to

'debug' => true, 

You can use TEXT like this as part of a concatenation

=TEXT(A1,"dd-mmm-yy") & " other string"

You could use the TimeSpan constructor which takes a long for Ticks:

 TimeSpan duration = new TimeSpan(endtime.Ticks - startTime.Ticks);

From jQuery:

Set the date to highlight on first opening if the field is blank. Specify either an actual date via a Date object or as a string in the current dateFormat, or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

Code examples

Initialize a datepicker with the defaultDate option specified.

$(".selector").datepicker({ defaultDate: +7 });

Get or set the defaultDate option, after init.

//getter
var defaultDate = $(".selector").datepicker("option", "defaultDate");
//setter
$(".selector").datepicker("option", "defaultDate", +7);

After the datepicker is intialized you should also be able to set the date with:

$(/*selector*/).datepicker("setDate" , date)

This question is pretty old, but it still seems important, as it isn't easy to put relative references from readme.md to wiki pages on Github.

I played around a little bit and this relative link seems to work pretty well:

[Your wiki page](../../wiki/your-wiki-page)

The two ../ will remove /blob/master/ and use your base as a starting point. I haven't tried this on other repositories than Github, though (there may be compatibility issues).

Control-C works, although depending on what the process is doing it might not take right away.

If you're on a unix based system, one thing I do is control-z to go back to the command line prompt and then issue a 'kill' to the process ID.

'RESTless' is a term not often used.

You can define 'RESTless' as any system that is not RESTful. For that it is enough to not have one characteristic that is required for a RESTful system.

Most systems are RESTless by this definition because they don't implement HATEOAS.

I completely forgot that I had previously installed another version of Apache Tomcat, which was causing this problem. So, just try uninstalling the previous version. Hope it helps.

You could do this with a single line:

yourEditText.RequestFocusFromTouch();

Here is a working example in both Javascript and jQuery:

http://jsfiddle.net/GuLYN/312/

//In jQuery
$("#calculate").click(function() {
    var num = parseFloat($("#textbox").val());
    var new_num = $("#textbox").val(num.toFixed(2));
});


// In javascript
document.getElementById('calculate').onclick = function() {
    var num = parseFloat(document.getElementById('textbox').value);
    var new_num = num.toFixed(2);
    document.getElementById('textbox').value = new_num;
};
?

I have used this way lots time ...

@Component({_x000D_
   selector: "data",_x000D_
   template: "<h1>{{ getData() }}</h1>"_x000D_

export class DataComponent{_x000D_
    this.http.get(path).subscribe({_x000D_

static setSubscribeData(data):any{_x000D_
    DataComponent.subscribeData=data;_x000D_
    return data;_x000D_
}

use static keyword and save your time... here either you can use static variable or directly return object you want.... hope it will help you.. happy coding...

Your terminal happens to be configured to UTF-8.

The fact that printing a works is a coincidence; you are writing raw UTF-8 bytes to the terminal. a is a value of length two, containing two bytes, hex values C3 and A1, while ua is a unicode value of length one, containing a codepoint U+00E1.

This difference in length is one major reason to use Unicode values; you cannot easily measure the number of text characters in a byte string; the len() of a byte string tells you how many bytes were used, not how many characters were encoded.

You can see the difference when you encode the unicode value to different output encodings:

>>> a = 'á'
>>> ua = u'á'
>>> ua.encode('utf8')
'\xc3\xa1'
>>> ua.encode('latin1')
'\xe1'
>>> a
'\xc3\xa1'

Note that the first 256 codepoints of the Unicode standard match the Latin 1 standard, so the U+00E1 codepoint is encoded to Latin 1 as a byte with hex value E1.

Furthermore, Python uses escape codes in representations of unicode and byte strings alike, and low code points that are not printable ASCII are represented using \x.. escape values as well. This is why a Unicode string with a code point between 128 and 255 looks just like the Latin 1 encoding. If you have a unicode string with codepoints beyond U+00FF a different escape sequence, \u.... is used instead, with a four-digit hex value.

It looks like you don't yet fully understand what the difference is between Unicode and an encoding. Please do read the following articles before you continue:

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky

• The Python Unicode HOWTO

• Pragmatic Unicode by Ned Batchelder

I sometimes use an approach that resembles to the answers using property injection, but keeps the code cleaner. Instead of having a base class/interface with a set of properties, it only contains a (virtual) Initialize()-method that acts as a "poor man's constructor". Then you can let each class handle it's own initialization just as a constructor would, which also adds a convinient way of handling inheritance chains.

If often find myself in situations where I want each class in the chain to initialize its unique properties, and then call its parent's Initialize()-method which in turn initializes the parent's unique properties and so forth. This is especially useful when having different classes, but with a similar hierarchy, for example business objects that are mapped to/from DTO:s.

Example that uses a common Dictionary for initialization:

void Main()
{
    var values = new Dictionary<string, int> { { "BaseValue", 1 }, { "DerivedValue", 2 } };

    Console.WriteLine(CreateObject<Base>(values).ToString());

    Console.WriteLine(CreateObject<Derived>(values).ToString());
}

public T CreateObject<T>(IDictionary<string, int> values)
    where T : Base, new()
{
    var obj = new T();
    obj.Initialize(values);
    return obj;
}

public class Base
{
    public int BaseValue { get; set; }

    public virtual void Initialize(IDictionary<string, int> values)
    {
        BaseValue = values["BaseValue"];
    }

    public override string ToString()
    {
        return "BaseValue = " + BaseValue;
    }
}

public class Derived : Base
{
    public int DerivedValue { get; set; }

    public override void Initialize(IDictionary<string, int> values)
    {
        base.Initialize(values);
        DerivedValue = values["DerivedValue"];
    }

    public override string ToString()
    {       
        return base.ToString() + ", DerivedValue = " + DerivedValue;
    }
}

You will need to parse the input to a DateTime object and then convert it to any text format you want.

If you are not sure what format you will get, you can restrict the user to a fixed format by using validation or datetimePicker, or some other component.

var res = exitDictionary
            .Select(p => p.Value).Cast<Dictionary<string, object>>()
            .SelectMany(d => d)
            .Where(p => p.Key == "fieldname1")
            .Select(p => p.Value).Cast<List<Dictionary<string,string>>>()
            .SelectMany(l => l)
            .SelectMany(d=> d)
            .Where(p => p.Key == "valueTitle")
            .Select(p => p.Value)
            .ToList();

This also works, and easy to understand.

This is still not fixed in Xcode Version 8.0 beta 2 (8S162m) for me and extra logs are also appearing in the Xcode console

** EDIT 8/1/16: This has been acknowledged in the release notes for Xcode 8 Beta 4 (8S188o) as an issues still persisting.

Known Issues in Xcode 8 beta 4 – IDE

Debugging

• Xcode Debug Console shows extra logging from system frameworks when debugging applications in the Simulator. (27331147, 26652255)

Presumably this will be resolved by the GM release. Until then patience and although not ideal but a workaround I'm using is below...

Similar to the previous answer I am having to:

• prefix my print logs with some kind of special character (eg * or ^ or ! etc etc)

• Then use the search box on the bottom right of the console pane to filter my console logs by inputing my chosen special character to get the console to display my print logs as intended

The <ul> element has browser inherent padding & margin by default. In your case, Use

#footer ul {
    margin: 0; /* To remove default bottom margin */ 
    padding: 0; /* To remove default left padding */
}

or a CSS browser reset ( https://cssreset.com/ ) to deal with this.

Missing the 'implements' keyword in the impl classes might also be the issue

If I understand your request correctly, you have to do the following:

public class Section 
{ 
    public String Head
    {
        get
        {
            return SubHead.LastOrDefault();
        }
        set
        {
            SubHead.Add(value);
        }

    public List<string> SubHead { get; private set; }
    public List<string> Content { get; private set; }
} 

You use it like this:

var section = new Section();
section.Head = "Test string";

Now "Test string" is added to the subHeads collection and will be available through the getter:

var last = section.Head; // last will be "Test string"

Hope I understood you correctly.

Yes, There is a difference, they're not the same. It's true that you'll get the same results but the engine works in a different way for both of them. One of them is an object literal, and the other one is a constructor, two different ways of creating an object in javascript.

var objectA = {} //This is an object literal

var objectB = new Object() //This is the object constructor

In JS everything is an object, but you should be aware about the following thing with new Object(): It can receive a parameter, and depending on that parameter, it will create a string, a number, or just an empty object.

For example: new Object(1), will return a Number. new Object("hello") will return a string, it means that the object constructor can delegate -depending on the parameter- the object creation to other constructors like string, number, etc... It's highly important to keep this in mind when you're managing dynamic data to create objects..

Many authors recommend not to use the object constructor when you can use a certain literal notation instead, where you will be sure that what you're creating is what you're expecting to have in your code.

I suggest you to do a further reading on the differences between literal notation and constructors on javascript to find more details.

I was inspired by Steve's answer but thought I'd add a bit of flare to it. I like to do the work up front of writing extension methods so later I have less work to do calling the method.

For example with the modified version of Steve's answer below, instead of making this call...

MyUtilities.RunCommandCom("DIR", "/W", true)

I can actually just type out the command and call it from my strings like this...

Directly in code.

Call "CD %APPDATA% & TREE".RunCMD()

OR

From a variable.

Dim MyCommand = "CD %APPDATA% & TREE"
MyCommand.RunCMD()

OR

From a textbox.

textbox.text.RunCMD(WaitForProcessComplete:=True)

Extension methods will need to be placed in a Public Module and carry the <Extension> attribute over the sub. You will also want to add Imports System.Runtime.CompilerServices to the top of your code file.

There's plenty of info on SO about Extension Methods if you need further help.

The OSIV Anti-Pattern

Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.

• The OpenSessionInViewFilter calls the openSession method of the underlying SessionFactory and obtains a new Session.
• The Session is bound to the TransactionSynchronizationManager.
• The OpenSessionInViewFilter calls the doFilter of the javax.servlet.FilterChain object reference and the request is further processed
• The DispatcherServlet is called, and it routes the HTTP request to the underlying PostController.
• The PostController calls the PostService to get a list of Post entities.
• The PostService opens a new transaction, and the HibernateTransactionManager reuses the same Session that was opened by the OpenSessionInViewFilter.
• The PostDAO fetches the list of Post entities without initializing any lazy association.
• The PostService commits the underlying transaction, but the Session is not closed because it was opened externally.
• The DispatcherServlet starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.
• The OpenSessionInViewFilter can close the Session, and the underlying database connection is released as well.

At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.

The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection as read-only which would allow the database server to avoid writing to the transaction log.

There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.

The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize for fetching associations in batches, and FetchMode.SUBSELECT to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.

Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.

Spring Boot and OSIV

Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.

So, make sure that in the application.properties configuration file, you have the following entry:

spring.jpa.open-in-view=false

This will disable OSIV so that you can handle the LazyInitializationException the right way.

Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.

If you're using zsh, you can use multiple redirections, so you don't even need tee:

./cmd 1>&1 2>&2 1>out_file 2>err_file

Here you're simply redirecting each stream to itself and the target file.

Full example

% (echo "out"; echo "err">/dev/stderr) 1>&1 2>&2 1>/tmp/out_file 2>/tmp/err_file
out
err
% cat /tmp/out_file
out
% cat /tmp/err_file
err

Note that this requires the MULTIOS option to be set (which is the default).

MULTIOS

Perform implicit tees or cats when multiple redirections are attempted (see Redirection).

As @stevebot said, do this:

https://<bucket-name>.s3.amazonaws.com/<key>

The one important thing I would like to add is that you either have to make your bucket objects all publicly accessible OR you can add a custom policy to your bucket policy. That custom policy could allow traffic from your network IP range or a different credential.

When you click on the image you'll get the alert:

<img src="logo1.jpg" onClick='alert("Hello World!")'/>

if this is what you want.

xmp is the way to go, i.e.:

<xmp>
  # your code...
</xmp>

If you have Oracle 10g, REGEXP_REPLACE is pretty flexible.

Using the following string as a test:

chr(9) || 'Q   qwer' || chr(9) || chr(10) ||
chr(13) || 'qwerqwer     qwerty' || chr(9) || 
chr(10) || chr(13)

The [[:space:]] will remove all whitespace, and the ([[:cntrl:]])|(^\t) regexp will remove non-printing characters and tabs.

select
    tester,
    regexp_replace(tester, '(^[[:space:]]+)|([[:space:]]+$)',null)
            regexp_tester_1,
    regexp_replace(tester, '(^[[:cntrl:]^\t]+)|([[:cntrl:]^\t]+$)',null) 
            regexp_tester_2
from
    (
    select
        chr(9) || 'Q   qwer' || chr(9) || chr(10) ||
                chr(13) || 'qwerqwer     qwerty' || chr(9) || 
                chr(10) || chr(13) tester 
    from 
        dual
    )

Returning:

• REGEXP_TESTER_1: "Qqwerqwerqwerqwerty"
• REGEXP_TESTER_2: "Q qwerqwerqwer qwerty"

Hope this is of some use.

Use Not IsNull(Fields!W_O_Count.Value)

All the answers provide sufficient details to the question. However, let me add something more.

Why are we using these Interfaces:

• They allow Spring to find your repository interfaces and create proxy objects for them.
• It provides you with methods that allow you to perform some common operations (you can also define your custom method as well). I love this feature because creating a method (and defining query and prepared statements and then execute the query with connection object) to do a simple operation really sucks !

Which interface does what:

• CrudRepository: provides CRUD functions
• PagingAndSortingRepository: provides methods to do pagination and sort records
• JpaRepository: provides JPA related methods such as flushing the persistence context and delete records in a batch

When to use which interface:

According to http://jtuts.com/2014/08/26/difference-between-crudrepository-and-jparepository-in-spring-data-jpa/

Generally the best idea is to use CrudRepository or PagingAndSortingRepository depending on whether you need sorting and paging or not.

The JpaRepository should be avoided if possible, because it ties you repositories to the JPA persistence technology, and in most cases you probably wouldn’t even use the extra methods provided by it.

How about using %/sprintf:

i = 20
"%x" % i  #=> "14"

You should be able to access the local database by using the name localhost. There is also a way to determine the hostname of the computer you're running on, but it doesn't sound like you need that. As for the username, you can either (1) give permissions to the account that PHP runs under to access the database without a password, or (2) store the username and password that you need to connect with (hard-coded or stored in a config file), and pass those as arguments to mysql_connect. See http://php.net/manual/en/function.mysql-connect.php.

There is a built-in method to get the bounding rectangle: Element.getBoundingClientRect.

The result is the smallest rectangle which contains the entire element, with the read-only left, top, right, bottom, x, y, width, and height properties.

See the example below:

let innerBox = document.getElementById("myDiv").getBoundingClientRect().height;_x000D_
document.getElementById("data_box").innerHTML = "height: " + innerBox;

body {_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.relative {_x000D_
  width: 220px;_x000D_
  height: 180px;_x000D_
  position: relative;_x000D_
  background-color: purple;_x000D_
}_x000D_
_x000D_
.absolute {_x000D_
  position: absolute;_x000D_
  top: 30px;_x000D_
  left: 20px;_x000D_
  background-color: orange;_x000D_
  padding: 30px;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
#myDiv {_x000D_
  margin: 20px;_x000D_
  padding: 10px;_x000D_
  color: red;_x000D_
  font-weight: bold;_x000D_
  background-color: yellow;_x000D_
}_x000D_
_x000D_
#data_box {_x000D_
  font: 30px arial, sans-serif;_x000D_

Solution

Apostrophes in the strings.xml should be written as

\'

Example

In my case I had an error with this string in my strings.xml and I fixed it.

<item>Most arguments can be ended with three words, "I don\'t care".</item>

Here you see my app builds properly with that code.

Here is the actual string in my app.

Using a HTTP debugging proxy can cause this - such as Fiddler.

I was loading a PFX certificate from a local file (authentication to Apple.com) and it failed because Fiddler wasn't able to pass this certificate on.

Try disabling Fiddler to check and if that is the solution then you need to probably install the certificate on your machine or in some way that Fiddler can use it.

I had the same problem. I tried lot of ways but at last solution was simple. Solution: Open IIS, In Application Pools, right click on the .net framework that is being used. Go to settings and change 'Enable 32-Bit Applications' to 'True'.

In python 3.x join() is used to join a thread with the main thread i.e. when join() is used for a particular thread the main thread will stop executing until the execution of joined thread is complete.

#1 - Without Join():
import threading
import time
def loiter():
    print('You are loitering!')
    time.sleep(5)
    print('You are not loitering anymore!')

t1 = threading.Thread(target = loiter)
t1.start()
print('Hey, I do not want to loiter!')
'''
Output without join()--> 
You are loitering!
Hey, I do not want to loiter!
You are not loitering anymore! #After 5 seconds --> This statement will be printed

'''
#2 - With Join():
import threading

We now use a privileged account management solution that changes our passwords regularly. I ended up receiving this error after my password was changed. Closing and re-opening SSMS with the new password resolved my issue.

If you want to do it typed:

class Something {

  areas: Area[][];

  constructor() {
    this.areas = new Array<Array<Area>>();
    for (let y = 0; y <= 100; y++) {
      let row:Area[]  = new Array<Area>();      
      for (let x = 0; x <=100; x++){
        row.push(new Area(x, y));
      }
      this.areas.push(row);
    }
  }
}

using eq appears to grab the dynamic DOM whereas using .parent().parent() appears to grab the DOM that was initially loaded (if that is even possible).

I use them both on an element that has classes applied it to on onmouseover. eq shows the classes while .parent().parent() doesnt.

I have a lengthy form (250+ fields) that posts to a db. It is an online employment application. When an admin goes to look at an application that has been filed, the form is populated with data from the db. Input texts and textareas are replaced with the text they submitted but the radios and checkboxes are useful to keep as form elements. Disabling them makes them harder to read. Setting the .checked property to false onclick won't work because they may have been checked by the user filling out the app. Anyhow...

onclick="return false;"

works like a charm for 'disabling' radios and checkboxes ipso facto.

Try File > New > Project... > Android Project From Existing Code. Don't copy your project from pc into workspace, copy it elsewhere and let the eclipse copy it into workspace by menu commands above and checking copy in existing workspace.

Create a dummy DOM element and add the string to it. Then, you can manipulate it like any DOM element.

var el = document.createElement( 'html' );
el.innerHTML = "<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>";

el.getElementsByTagName( 'a' ); // Live NodeList of your anchor elements

Edit: adding a jQuery answer to please the fans!

var el = $( '<div></div>' );
el.html("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>");

$('a', el) // All the anchor elements

Also u may insert befor Schema::create('books', function(Blueprint $table) the following code Schema::drop('books');

Kent Beck suggests:

• One test fixture per 'unit' (class of your program). Test fixtures are classes themselves. The test fixture name should be:

  [name of your 'unit']Tests
  

• Test cases (the test fixture methods) have names like:

  test[feature being tested]
  

For example, having the following class:

class Person {
    int calculateAge() { ... }

    // other methods and properties
}

A test fixture would be:

class PersonTests {

    testAgeCalculationWithNoBirthDate() { ... }

    // or

    testCalculateAge() { ... }
}

Agree no matches in your example.
If you mean both columns on either then need a query like this or need to re-examine the data design.

    Select TableA.Col1, TableA.Col2, TableB.Val
    FROM TableA
    INNER JOIN TableB
          ON TableA.Col1 = TableB.Col1 OR TableA.Col2 = TableB.Col2

Find the folder containing the shared library libopencv_core.so.2.4 using the following command line.

sudo find / -name "libopencv_core.so.2.4*"

Then I got the result:

 /usr/local/lib/libopencv_core.so.2.4.

Create a file called /etc/ld.so.conf.d/opencv.conf and write to it the path to the folder where the binary is stored.For example, I wrote /usr/local/lib/ to my opencv.conf file. Run the command line as follows.

sudo ldconfig -v

Try to run the command again.

As per MSDN the default value is 4096 KB (4 MB).

UPDATE

As for the Maximum, since it is an int data type, then theoretically you can go up to 2,147,483,647. Also I wanted to make sure that you are aware that IIS 7 uses maxAllowedContentLength for specifying file upload size. By default it is set to 30000000 around 30MB and being an uint, it should theoretically allow a max of 4,294,967,295

Using select-string:

Get-EventLog Security | where {$_.UserName | select-string -notmatch user1,user2}

This becomes a one-liner if you download File Checksum Integrity Verifier (FCIV) from Microsoft.

I downloaded FCIV from here: Availability and description of the File Checksum Integrity Verifier utility

Run the following command. I had ten files to check.

Get-ChildItem WTAM*.tar | % {.\fciv $_.Name}

Yes,Closure (Lambda Expressions) is the new feature with the upcoming Java SE 8 release. You can get more info about this from the below link: http://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html

No, the way that you're doing it is just fine. implode() only takes 1-2 parameters (if you just supply an array, it joins the pieces by an empty string).

The following example should demonstrate the difference:

String destroyTheWorld() {
  // destroy the world logic
  return "successfully destroyed the world";
}

Optional<String> opt = Optional.of("Save the world");

// we're dead
opt.orElse(destroyTheWorld());

// we're safe    
opt.orElseGet(() -> destroyTheWorld());

The answer appears in the docs as well.

public T orElseGet(Supplier<? extends T> other):

Return the value if present, otherwise invoke other and return the result of that invocation.

The Supplier won't be invoked if the Optional presents. whereas,

public T orElse(T other):

Return the value if present, otherwise return other.

If other is a method that returns a string, it will be invoked, but it's value won't be returned in case the Optional exists.

I assume you want to center them on one line and not on two separate lines based on your fiddle. If that is the case, try the following css:

 div { background:red;
      overflow:hidden;
}
span { display:block;
       margin:0 auto;
       width:200px;
}
span a { padding:5px 10px;
         color:#fff;
         background:#222;
}

I removed the float since you want to center it, and then made the span surrounding the links centered by adding margin:0 auto to them. Finally, I added a static width to the span. This centers the links on one line within the red div.

I use lists to filter dataframes by whether or not they have a value %in% a list.

I had been manually creating lists by exporting a 1 column dataframe to Excel where I would add " ", around each element, before pasting into R: list <- c("el1", "el2", ...) which was usually followed by FilteredData <- subset(Data, Column %in% list).

After searching stackoverflow and not finding an intuitive way to convert a 1 column dataframe into a list, I am now posting my first ever stackoverflow contribution:

# assuming you have a 1 column dataframe called "df"
list <- c()
for(i in 1:nrow(df)){
  list <- append(list, df[i,1])
}
View(list)
# This list is not a dataframe, it is a list of values
# You can filter a dataframe using "subset([Data], [Column] %in% list")

In this problem , i've used some arithmetic solution . Thanks :)

int main(void)
{
    int n, x = 10, i = 1;
    scanf("%d", &n);
    while(n / x > 0)
    {
        x*=10;
        i++;
    }
    printf("the number contains %d digits\n", i);

    return 0;
}

Your x and y values ??are not running so first of all youre begin to write this point

 import numpy as np
 import pandas as pd
 import matplotlib as plt

 dataframe=pd.read_csv(".\datasets\Position_Salaries.csv")

 x=dataframe.iloc[:,1:2].values 
 y=dataframe.iloc[:,2].values    
 x1=dataframe.iloc[:,:-1].values 

point of value have publish

Using the "point" leads to the creation of a folder named "point" (on Ubuntu 16).

tar -tf site1.bz2 -C /var/www/site1/ .

    -C /var/www/site1/ index.html\

You can use setColumnWidth() if you want to expand your cell more.

You're getting the error message

ValueError: setting an array element with a sequence.

because you're trying to set an array element with a sequence. I'm not trying to be cute, there -- the error message is trying to tell you exactly what the problem is. Don't think of it as a cryptic error, it's simply a phrase. What line is giving the problem?

kOUT[i]=func(TempLake[i],Z)

This line tries to set the ith element of kOUT to whatever func(TempLAke[i], Z) returns. Looking at the i=0 case:

In [39]: kOUT[0]
Out[39]: 0.0

In [40]: func(TempLake[0], Z)
Out[40]: array([ 0.,  0.,  0.,  0.])

You're trying to load a 4-element array into kOUT[0] which only has a float. Hence, you're trying to set an array element (the left hand side, kOUT[i]) with a sequence (the right hand side, func(TempLake[i], Z)).

Probably func isn't doing what you want, but I'm not sure what you really wanted it to do (and don't forget you can usually use vectorized operations like A*B rather than looping in numpy.) That should explain the problem, anyway.

An app is available that demonstrates a listview that combines both swiping-to-delete and dragging to reorder items. The code is based on Chet Haase's code for swiping-to-delete and Daniel Olshansky's code for dragging-to-reorder.

Chet's code deletes an item immediately. I improved on this by making it function more like Gmail where swiping reveals a bottom view that indicates that the item is deleted but provides an Undo button where the user has the possibility to undo the deletion. Chet's code also has a bug in it. If you have less items in the listview than the height of the listview is and you delete the last item, the last item appears to not be deleted. This was fixed in my code.

Daniel's code requires pressing long on an item. Many users find this unintuitive as it tends to be a hidden function. Instead, I modified the code to allow for a "Move" button. You simply press on the button and drag the item. This is more in line with the way the Google News app works when you reorder news topics.

The source code along with a demo app is available at: https://github.com/JohannBlake/ListViewOrderAndSwipe

Chet and Daniel are both from Google.

Chet's video on deleting items can be viewed at: https://www.youtube.com/watch?v=YCHNAi9kJI4

A considerable amount of work went into gluing all this together to provide a seemless UI experience, so I'd appreciate a Like or Up Vote. Please also star the project in Github.

The first methods seem to work in the browsers that I tested, but the option tags doesn't really correspond to actual elements in all browsers, so the result may vary.

Just use the selectedIndex property of the DOM element:

alert($("#dropDownMenuKategorie")[0].selectedIndex);

Update:

Since version 1.6 jQuery has the prop method that can be used to read properties:

alert($("#dropDownMenuKategorie").prop('selectedIndex'));

Here's some that I needed to include the date-time stamp in the folder name for dumping files from a web scraper.

# import time and OS modules to use to build file folder name
import time
import os 

# Build string for directory to hold files
# Output Configuration
#   drive_letter = Output device location (hard drive) 
#   folder_name = directory (folder) to receive and store PDF files

drive_letter = r'D:\\' 
folder_name = r'downloaded-files'
folder_time = datetime.now().strftime("%Y-%m-%d_%I-%M-%S_%p")
folder_to_save_files = drive_letter + folder_name + folder_time 

# IF no such folder exists, create one automatically
if not os.path.exists(folder_to_save_files):
    os.mkdir(folder_to_save_files)

Not sure if this is already answered, but if you want only a table in a figure window, then you can hide the axes:

fig, ax = plt.subplots()

# Hide axes
ax.xaxis.set_visible(False) 
ax.yaxis.set_visible(False)

# Table from Ed Smith answer
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
ax.table(cellText=clust_data,colLabels=collabel,loc='center')

Such an old question, but maybe I can propose an alternative solution.

You can use the install programme to copy your file and create the destination path "on the fly".

install -D file /path/to/copy/file/to/is/very/deep/there/file

There are some aspects to take in consideration, though:

1. you need to specify also the destination file name, not only the destination path
2. the destination file will be executable (at least, as far as I saw from my tests)

You can easily amend the #2 by adding the -m option to set permissions on the destination file (example: -m 664 will create the destination file with permissions rw-rw-r--, just like creating a new file with touch).

And here it is the shameless link to the answer I was inspired by =)

The "pre" and "post" nature of increment and decrement operators can tend to be confusing for those who are not familiar with them; that's one way in which they can be tricky.

Something like this should work:

INSERT INTO #IMEIS (imei) VALUES ('val1'), ('val2'), ...

UPDATE:

Apparently this syntax is only available starting on SQL Server 2008.

<EditText android:imeOptions="actionDone"
          android:inputType="text"/>

The Java code is:

edittext.setOnEditorActionListener(new OnEditorActionListener() { 
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            Log.i(TAG,"Here you can write the code");
            return true;
        }    
        return false;
    }
});

The only way I know to deal with this is to create a new workspace, import projects from the polluted workspace, reconstructing all my settings (a major pain) and then delete the old workspace. Is there an easier way to deal with this?

For synchronizing or restoring all our settings we use Workspace Mechanic. Once all the settings are recorded its one click and all settings are restored... You can also setup a server which provides those settings for all users.

Here is very simple example

input[type="radio"]{_x000D_
   display:none;_x000D_
}_x000D_
_x000D_
input[type="radio"] + label_x000D_
{_x000D_

    height: 100px;_x000D_
    width: 100px;_x000D_
    display:inline-block;_x000D_
    padding: 0 0 0 0px;_x000D_
    cursor:pointer;_x000D_
}_x000D_
_x000D_
input[type="radio"]:checked + label_x000D_
{_x000D_
    background-image:url(http://www.clker.com/cliparts/M/2/V/6/F/u/radiobutton-checked-sm-md.png);_x000D_
}

<div>_x000D_
  <input type="radio" id="shipadd1" value=1 name="address" />_x000D_
  <label for="shipadd1"></label>_x000D_
  value 1_x000D_
</div>_x000D_
_x000D_
<div>_x000D_

This example based on this trick: https://css-tricks.com/the-checkbox-hack/

I tested it on: chrome, firefox, safari

To run usually click and it should run, that is if you have java installed. If not get java from here Sorry thought it was more general open a command prompt and type java -jar jbpm-installer-3.2.7.jar

If you have other testing applications like SQL web batch etc, uninstall them because they are running in port 3306.

Take advantage of as.matrix:

# keep the first column 
names <-  df.aree[,1]

# Transpose everything other than the first column
df.aree.T <- as.data.frame(as.matrix(t(df.aree[,-1])))

# Assign first column as the column names of the transposed dataframe
colnames(df.aree.T) <- names

Correct on all fronts. Outside of a character class (that's what the "square brackets" are called) the hyphen has no special meaning, and within a character class, you can place a hyphen as the first or last character in the range (e.g. [-a-z] or [0-9-]), OR escape it (e.g. [a-z\-0-9]) in order to add "hyphen" to your class.

It's more common to find a hyphen placed first or last within a character class, but by no means will you be lynched by hordes of furious neckbeards for choosing to escape it instead.

(Actually... my experience has been that a lot of regex is employed by folks who don't fully grok the syntax. In these cases, you'll typically see everything escaped (e.g. [a-z\%\$\#\@\!\-\_]) simply because the engineer doesn't know what's "special" and what's not... so they "play it safe" and obfuscate the expression with loads of excessive backslashes. You'll be doing yourself, your contemporaries, and your posterity a huge favor by taking the time to really understand regex syntax before using it.)

Great question!

I tried accepted answer and got message saying generated excel file is corrupted when trying to open. I was able to fix it by doing few modifications like adding below line end of the code.

workbookPart.Workbook.Save();

I have posted full code @ Export DataTable to Excel with Open XML in c#

List-returning map function has the advantage of saving typing, especially during interactive sessions. You can define lmap function (on the analogy of python2's imap) that returns list:

lmap = lambda func, *iterable: list(map(func, *iterable))

Then calling lmap instead of map will do the job: lmap(str, x) is shorter by 5 characters (30% in this case) than list(map(str, x)) and is certainly shorter than [str(v) for v in x]. You may create similar functions for filter too.

There was a comment to the original question:

I would suggest a rename to Getting map() to return a list in Python 3.* as it applies to all Python3 versions. Is there a way to do this? – meawoppl Jan 24 at 17:58

It is possible to do that, but it is a very bad idea. Just for fun, here's how you may (but should not) do it:

__global_map = map #keep reference to the original map
lmap = lambda func, *iterable: list(__global_map(func, *iterable)) # using "map" here will cause infinite recursion
map = lmap
x = [1, 2, 3]
map(str, x) #test
map = __global_map #restore the original map and don't do that again
map(str, x) #iterator

Select Into functionality only works for PL/SQL Block, when you use Execute immediate , oracle interprets v_query_str as a SQL Query string so you can not use into .will get keyword missing Exception. in example 2 ,we are using begin end; so it became pl/sql block and its legal.

Handle the Worksheet_Change event or the Workbook_SheetChange event.

The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.

You may try like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {
    g.drawRect (x, y, width, height);    //can use either of the two//
    g.fillRect (x, y, width, height);
    g.setColor(color);
  }

}

where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue

if you want to use rectangle object you could do it like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {    
    Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
    g.setColor(color);
  }
}       

I assume you are using integers to represent your year, month, and day? If you want to remain consistent, use the Date methods.

Calendar cal = new Calendar();
int currentYear, currentMonth, currentDay; 
currentYear = cal.get(Calendar.YEAR); 
currentMonth = cal.get(Calendar.MONTH); 
currentDay = cal.get(Calendar.DAY_OF_WEEK);

     if(startYear < currentYear)
                {
                    message = message + "Start Date is Before Today" + "\n";
                }
            else if(startMonth < currentMonth && startYear <= currentYear)
                    {
                        message = message + "Start Date is Before Today" + "\n";
                    }
            else if(startDay < currentDay && startMonth <= currentMonth && startYear <= currentYear)
                        {
                            message = message + "Start Date is Before Today" + "\n";
                        }

after 5 long years I'm sure not much attention is going to be received for this answer, But still to make all options complete, here is the one with data.table

library(data.table)
setDT(df)[ , list(mean_gr = mean(dt), sum_gr = sum(dt)) , by = .(group)]
#   group mean_gr sum_gr
#1:     A      61    244
#2:     B      66    396
#3:     C      68    408
#4:     D      61    488 

Observable values can be retrieved from any locations. The source sequence is first pushed onto a special observer that is able to emit elsewhere. This is achieved with the Subject class from the Reactive Extensions (RxJS).

var subject = new Rx.AsyncSubject();  // store-last-value method

Store value onto the observer.

subject.next(value); // store value
subject.complete(); // publish only when sequence is completed

To retrieve the value from elsewhere, subscribe to the observer like so:

subject.subscribe({
  next: (response) => {
      //do stuff. The property name "response" references the value
  }
});

Subjects are both Observables and Observers. There are other Subject types such as BehaviourSubject and ReplaySubject for other usage scenarios.

Don't forget to import RxJS.

var Rx = require('rxjs');

I have 2 alarms. I am using intent with extras instead of action to identify the events:

Intent i = new Intent(context, AppReciever.class);
i.putExtra("timer", "timer1");

the thing is that with diff extras the intent (and the alarm) wont be unique. So to able to identify which alarm is active or not, I had to define diff requestCode-s:

boolean alarmUp = (PendingIntent.getBroadcast(context, MyApp.TIMER_1, i, 
                    PendingIntent.FLAG_NO_CREATE) != null);

and here is how alarm was created:

public static final int TIMER_1 = 1;
public static final int TIMER_2 = 2;

PendingIntent pending = PendingIntent.getBroadcast(context, TIMER_1, i,
            PendingIntent.FLAG_CANCEL_CURRENT);
setInexactRepeating(AlarmManager.RTC_WAKEUP,
            cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pending);
pending = PendingIntent.getBroadcast(context, TIMER_2, i,
            PendingIntent.FLAG_CANCEL_CURRENT);
setInexactRepeating(AlarmManager.RTC_WAKEUP,
            cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pending);

You can use column indices (letters) like this:

import pandas as pd
import numpy as np
file_loc = "path.xlsx"
df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")
print(df)

[Corresponding documentation][1]:

usecolsint, str, list-like, or callable default None

• If None, then parse all columns.
• If str, then indicates comma separated list of Excel column letters and column ranges (e.g. “A:E” or “A,C,E:F”). Ranges are inclusive of both sides.
• If list of int, then indicates list of column numbers to be parsed.

• If list of string, then indicates list of column names to be parsed.

  New in version 0.24.0.

• If callable, then evaluate each column name against it and parse the column if the callable returns True.

Returns a subset of the columns according to behavior above.

New in version 0.24.0.

adbd has a compilation flag/option to enable root access: ALLOW_ADBD_ROOT=1.

Up to Android 9: If adbd on your device is compiled without that flag, it will always drop privileges when starting up and thus "adb root" will not help at all. I had to patch the calls to setuid(), setgid(), setgroups() and the capability drops out of the binary myself to get a permanently rooted adbd on my ebook reader.

With Android 10 this changed; when the phone/tablet is unlocked (ro.boot.verifiedbootstate == "orange"), then adb root mode is possible in any case.

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

For Full like you can user :

$this->db->like('title',$query);

For %$query you can use

$this->db->like('title', $query, 'before');

and for $query% you can use

$this->db->like('title', $query, 'after');

I would try setting it to max-width:50px;

This can be done using the unique function in ufp.path module.

Regarding other languages, you might want to poke around on Wiktionary. Here is a link to all the database backups - the information isnt organized so likely but if they have a language, you can download the data in SQL format.

The auto keyword specifies that the type of the variable that is being declared will be automatically deducted from its initializer. In case of functions, if their return type is auto then that will be evaluated by return type expression at runtime.

It can be very useful when we have to use the iterator. For e.g. for below code we can simply use the "auto" instead of writing the whole iterator syntax .

int main() 
{ 

// Initialize set 
set<int> s; 

s.insert(1); 
s.insert(4); 
s.insert(2); 
s.insert(5); 
s.insert(3); 

// iterator pointing to 
// position where 2 is 
auto pos = s.find(3); 

// prints the set elements 
cout << "The set elements after 3 are: "; 
for (auto it = pos; it != s.end(); it++) 
    cout << *it << " "; 

return 0; 
}

This is how we can use "auto" keyword

Solution for Unix-like operating system.

1. Create a directory named like Images and put all the images that will be rendered by the Markdown.

2. For example, put example.png into Images.

3. To load example.png that was located under the Images directory before.

![title](Images/example.png)

Note : Images directory must be located under the same directory of your markdown text file which has .md extension.

http://php.net/manual/en/language.types.string.php says:

Note: As of PHP 7.0.0, there are no particular restrictions regarding the length of a string on 64-bit builds. On 32-bit builds and in earlier versions, a string can be as large as up to 2GB (2147483647 bytes maximum)

In PHP 5.x, strings were limited to 2³¹-1 bytes, because internal code recorded the length in a signed 32-bit integer.

You can slurp in the contents of an entire file, for instance using file_get_contents()

However, a PHP script has a limit on the total memory it can allocate for all variables in a given script execution, so this effectively places a limit on the length of a single string variable too.

This limit is the memory_limit directive in the php.ini configuration file. The memory limit defaults to 128MB in PHP 5.2, and 8MB in earlier releases.

If you don't specify a memory limit in your php.ini file, it uses the default, which is compiled into the PHP binary. In theory you can modify the source and rebuild PHP to change this default value.

If you specify -1 as the memory limit in your php.ini file, it stop checking and permits your script to use as much memory as the operating system will allocate. This is still a practical limit, but depends on system resources and architecture.

Re comment from @c2:

Here's a test:

<?php

// limit memory usage to 1MB 
ini_set('memory_limit', 1024*1024);

// initially, PHP seems to allocate 768KB for basic operation
printf("memory: %d\n",  memory_get_usage(true));

$str = str_repeat('a',  255*1024);
echo "Allocated string of 255KB\n";

// now we have allocated all of the 1MB of memory allowed
printf("memory: %d\n",  memory_get_usage(true));

// going over the limit causes a fatal error, so no output follows
$str = str_repeat('a',  256*1024);
echo "Allocated string of 256KB\n";
printf("memory: %d\n",  memory_get_usage(true));

Your if statements are checking for int values. raw_input returns a string. Change the following line:

tSizeAns = raw_input() 

to

tSizeAns = int(raw_input()) 

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

This is how I do it for popups, though it is only working with IE11, not Chrome- haven't tested in Firefox.

window.open(url, title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no');

It is important to keep in mind that let is lazy evaluated and not putting side-effect methods in it otherwise you would not be able to change from let to before(:each) easily. You can use let! instead of let so that it is evaluated before each scenario.

Just issue the sequence of the steps: drop the database, then re-create it again, migrate data, and if you have seeds, sow the database:

rake db:drop db:create db:migrate db:seed

Since the default environment for rake is development, in case if you see the exception in spec tests, you should re-create db for the test environment as follows:

RAILS_ENV=test rake db:drop db:create db:migrate

In most cases the test database is being sowed during the test procedures, so db:seed task action isn't required to be passed. Otherwise, you shall to prepare the database:

rake db:test:prepare

or

RAILS_ENV=test rake db:seed

Additionally, to use the recreate task you can add into Rakefile the following code:

namespace :db do
   task :recreate => [ :drop, :create, :migrate ] do
      if ENV[ 'RAILS_ENV' ] !~ /test|cucumber/
         Rake::Task[ 'db:seed' ].invoke
      end
   end
end

Then issue:

rake db:recreate

There are many benefits of using pointers to object -

1. Efficiency (as you already pointed out). Passing objects to functions mean creating new copies of object.
2. Working with objects from third party libraries. If your object belongs to a third party code and the authors intend the usage of their objects through pointers only (no copy constructors etc) the only way you can pass around this object is using pointers. Passing by value may cause issues. (Deep copy / shallow copy issues).
3. if the object owns a resource and you want that the ownership should not be sahred with other objects.

How large are the values? Java 6 has Scanner class that can read anything from int (32 bit), long (64-bit) to BigInteger (arbitrary big integer).

For Java 5 or 4, Scanner is there, but no support for BigInteger. You have to read line by line (with readLine of Scanner class) and create BigInteger object from the String.

try this

 final TelephonyManager tm =(TelephonyManager)getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);

  String deviceid = tm.getDeviceId();

I did everything above but had to do one more thing in IntelliJ:

Project Structure > Modules

I had to change every module's "language level"

The t indicates text mode, meaning that \n characters will be translated to the host OS line endings when writing to a file, and back again when reading. The flag is basically just noise, since text mode is the default.

Other than U, those mode flags come directly from the standard C library's fopen() function, a fact that is documented in the sixth paragraph of the python2 documentation for open().

As far as I know, t is not and has never been part of the C standard, so although many implementations of the C library accept it anyway, there's no guarantee that they all will, and therefore no guarantee that it will work on every build of python. That explains why the python2 docs didn't list it, and why it generally worked anyway. The python3 docs make it official.

Lately I created a chrome extension "eXtract Snippet" for copying the inspected element, html and only the relevant css and media queries from a page. Note that this would give you the actual relevant CSS

https://chrome.google.com/webstore/detail/extract-snippet/bfcjfegkgdoomgmofhcidoiampnpbdao?hl=en

My guess is that it indicates "Unicode", is it correct?

Yes.

If so, since when is it available?

Python 2.x.

In Python 3.x the strings use Unicode by default and there's no need for the u prefix. Note: in Python 3.0-3.2, the u is a syntax error. In Python 3.3+ it's legal again to make it easier to write 2/3 compatible apps.

                                       .collect(Collectors.toList());

The return value would be arrays of split string. This avoids converting the arraylist to an array and performing the operation.

fibonacci 1,000 ... 10,000 ... 100,000

Some answers run into issues when trying to calculate large fibonacci numbers. Others are approximating numbers using phi. This answer will show you how to calculate a precise series of large fibonacci numbers without running into limitations set by JavaScript's floating point implementation.

Below, we generate the first 1,000 fibonacci numbers in a few milliseconds. Later, we'll do 100,000!

const { fromInt, toString, add } =
  Bignum

const bigfib = function* (n = 0)
{
  let a = fromInt (0)
  let b = fromInt (1)
  let _
  while (n >= 0) {
    yield toString (a)
    _ = a
    a = b
    b = add (b, _)
    n = n - 1
  }
}

console.time ('bigfib')
const seq = Array.from (bigfib (1000))
console.timeEnd ('bigfib')
// 25 ms

console.log (seq.length)
// 1001

console.log (seq)
// [ 0, 1, 1, 2, 3, ... 995 more elements ]

Let's see the 1,000th fibonacci number

console.log (seq [1000])
// 43466557686937456435688527675040625802564660517371780402481729089536555417949051890403879840079255169295922593080322634775209689623239873322471161642996440906533187938298969649928516003704476137795166849228875

10,000

This solution scales quite nicely. We can calculate the first 10,000 fibonacci numbers in under 2 seconds. At this point in the sequence, the numbers are over 2,000 digits long – way beyond the capacity of JavaScript's floating point numbers. Still, our result includes precise values without making approximations.

console.time ('bigfib')
const seq = Array.from (bigfib (10000))
console.timeEnd ('bigfib')
// 1877 ms

console.log (seq.length)
// 10001

console.log (seq [10000] .length)
// 2090

console.log (seq [10000])
// 3364476487 ... 2070 more digits ... 9947366875

Of course all of that magic takes place in Bignum, which we will share now. To get an intuition for how we will design Bignum, recall how you added big numbers using pen and paper as a child...

  1259601512351095520986368
+   50695640938240596831104
---------------------------
                          ?

You add each column, right to left, and when a column overflows into the double digits, remembering to carry the 1 over to the next column...

                 ... <-001
  1259601512351095520986368
+   50695640938240596831104
---------------------------
                  ... <-472

Above, we can see that if we had two 10-digit numbers, it would take approximately 30 simple additions (3 per column) to compute the answer. This is how we will design Bignum to work

const Bignum =
  { fromInt: (n = 0) =>
      n < 10
        ? [ n ]
        : [ n % 10, ...Bignum.fromInt (n / 10 >> 0) ]

  , fromString: (s = "0") =>
      Array.from (s, Number) .reverse ()

  , toString: (b) =>
      Array.from (b) .reverse () .join ('')

  , add: (b1, b2) =>
    {
      const len = Math.max (b1.length, b2.length)
      let answer = []
      let carry = 0
      for (let i = 0; i < len; i = i + 1) {
        const x = b1[i] || 0
        const y = b2[i] || 0
        const sum = x + y + carry
        answer.push (sum % 10)
        carry = sum / 10 >> 0
      }
      if (carry > 0) answer.push (carry)
      return answer
    }
  }

We'll run a quick test to verify our example above

const x =
  fromString ('1259601512351095520986368')

const y =
  fromString ('50695640938240596831104')

console.log (toString (add (x,y)))
// 1310297153289336117817472

100,000

I was just curious how far this little script could go. It seems like the only limitation is just time and memory. Below, we calculate the first 100,000 fibonacci numbers without approximation. Numbers at this point in the sequence are over 20,000 digits long, wow! It takes 3.18 minutes to complete but the result still matches the answer from wolfram alpha

console.time ('bigfib')
const seq = Array.from (bigfib (100000))
console.timeEnd ('bigfib')
// 191078 ms

console.log (seq .length)
// 100001

console.log (seq [100000] .length)
// 20899

console.log (seq [100000])
// 2597406934 ... 20879 more digits ... 3428746875

In cases where the name attribute is different it is easiest to control the radio group via JQuery. When an option is selected use JQuery to un-select the other options.

integer division in C truncates the result so 50/100 will give you 0

If you want to get the desired result try this :

((float)number/total)*100

or

50.0/100

I would like to add to the answers of BalusC and Pascal Thivent another common use of insertable=false, updatable=false:

Consider a column that is not an id but some kind of sequence number. The responsibility for calculating the sequence number may not necessarily belong to the application.

For example, sequence number starts with 1000 and should increment by one for each new entity. This is easily done, and very appropriately so, in the database, and in such cases these configurations makes sense.

As stated in

How can I change where Vagrant looks for its virtual hard drive?

the virtual-machine state is stored in a predefined VirtualBox folder. Copying the corresponding machine (folder) besides your vagrant-project to your other host should preserve your virtual machine state.

In your intiallizer/carrierwave.rb

if Rails.env.development? || Rails.env.test?
    config.storage = :file
    config.root = "#{Rails.root}/public"
    if Rails.env.test?
      CarrierWave.configure do |config|
        config.storage = :file
        config.enable_processing = false
      end
    end
 end

use this to store in a file while running on local

You can also use equals:

 Integer a = 0;

 if (a.equals(0)) {
     // a == 0
 }

which is equivalent to:

 if (a.intValue() == 0) {
     // a == 0
 }

and also:

 if (a == 0) {

 }

(the Java compiler automatically adds intValue())

Note that autoboxing/autounboxing can introduce a significant overhead (especially inside loops).

I got this by not having the project set as startup, as indicated by another answer. My contribution to this - when doing Add-Migrations and Update-Database, specify the startup project as part of the command in Nuget Package Manager Console (do not include the '[' or ']' characters, that's just to show you that you need to change the text located there to your project name):

1. Enable-Migrations
2. Add-Migrations -StartupProject [your project name that contains the data context class]
3. Update-Database -StartupProject [same project name as above]

That should do it.

controller_name holds the name of the controller used to serve the current view.

    ss_res = ((y-y_hat)**2).sum()
    return 1 - (ss_res/ss_tot)

There are several possibilities, what's best depends on the text you work on.

Two possibilities come to mind:

• delete a whole paragraph with: dap

ApplicationContext (Root Application Context) : Every Spring MVC web application has an applicationContext.xml file which is configured as the root of context configuration. Spring loads this file and creates an applicationContext for the entire application. This file is loaded by the ContextLoaderListener which is configured as a context param in web.xml file. And there will be only one applicationContext per web application.

WebApplicationContext : WebApplicationContext is a web aware application context i.e. it has servlet context information. A single web application can have multiple WebApplicationContext and each Dispatcher servlet (which is the front controller of Spring MVC architecture) is associated with a WebApplicationContext. The webApplicationContext configuration file *-servlet.xml is specific to a DispatcherServlet. And since a web application can have more than one dispatcher servlet configured to serve multiple requests, there can be more than one webApplicationContext file per web application.

Basically what you have is two vectors, one vector from P1 to P2 and another from P1 to P3. So all you need is an formula to calculate the angle between two vectors.

Have a look here for a good explanation and the formula.

I haven't seen equivalent to late solution I'm going to give, so here it is.

use offsets to move values from default 0 into any value you like. here properties must be used instead of directly accessing fields. (maybe with possible c#7 feature you better define property scoped fields so they remain protected from being directly accessed in code.)

This solution works for simple structs with only value types (no ref type or nullable struct).

public struct Tempo
{
    const double DefaultBpm = 120;
    private double _bpm; // this field must not be modified other than with its property.

    public double BeatsPerMinute
    {
        get => _bpm + DefaultBpm;
        set => _bpm = value - DefaultBpm;
    }
}

This is different than this answer, this approach is not especial casing but its using offset which will work for all ranges.

example with enums as field.

public struct Difficaulty
{
    Easy,
    Medium,
    Hard
}

public struct Level
{
    const Difficaulty DefaultLevel = Difficaulty.Medium;
    private Difficaulty _level; // this field must not be modified other than with its property.

    public Difficaulty Difficaulty
    {
        get => _level + DefaultLevel;
        set => _level = value - DefaultLevel;
    }
}

As I said this trick may not work in all cases, even if struct has only value fields, only you know that if it works in your case or not. just examine. but you get the general idea.

int i = 65;
char c = Convert.ToChar(i);

If you just need to resync windows time, open an elevated command prompt and type:

w32tm /resync

C:\WINDOWS\system32>w32tm /resync 
Sending resync command to local computer 
The command completed successfully.

The _ character is also a wildcard, BTW, but I'm not sure why this wasn't working for you:

CREATE TRIGGER 
    [dbo].[SystemParameterInsertUpdate]
ON 
    [dbo].[SystemParameter]
FOR INSERT, UPDATE 
AS
  BEGIN
    SET NOCOUNT ON
      INSERT INTO SystemParameterHistory 
      (
        Attribute,
        ParameterValue,
        ParameterDescription,
        ChangeDate
      )
    SELECT
      I.Attribute,
      I.ParameterValue,
      I.ParameterDescription,
      I.ChangeDate
    FROM Inserted AS I
    WHERE I.Attribute NOT LIKE 'NoHist[_]%'
END

You can do something like this

var now = moment();
var time = now.hour() + ':' + now.minutes() + ':' + now.seconds();
time = time + ((now.hour()) >= 12 ? ' PM' : ' AM');

The inconvenience of typing 10 < x && x < 20 is minimal compared to the increase in language complexity if one would allow 10 < x < 20, so the designers of the Java language decided against supporting it.

{

        UIImageView *background = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cs_lines_back.png"]] autorelease];
        theTableView.backgroundView = background;

}

Hope this helps

Use the following code it worked for me:

# Create the figure
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Generate the values
x_vals = X_iso[:, 0:1]
y_vals = X_iso[:, 1:2]
z_vals = X_iso[:, 2:3]

# Plot the values
ax.scatter(x_vals, y_vals, z_vals, c = 'b', marker='o')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')

plt.show()

while X_iso is my 3-D array and for X_vals, Y_vals, Z_vals I copied/used 1 column/axis from that array and assigned to those variables/arrays respectively.

Run this script from SharePoint 2010 Management Shell as Administrator.

Your code is just fine. The reason you're getting a black screen is because there's nothing on your second view controller.

Try something like:

secondViewController.view.backgroundColor = UIColor.redColor();

Now the view controller it shows should be red.

To actually do something with secondViewController, create a subclass of UIViewController and instead of

let secondViewController:UIViewController = UIViewController()

create an instance of your second view controller:

//If using code
let secondViewController = MyCustomViewController.alloc()

//If using storyboard, assuming you have a view controller with storyboard ID "MyCustomViewController"
let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("MyCustomViewController") as UIViewController

You can use sum():

>>> sum([True, True, False, False, False, True])
3

I'm assuming that's an ARGB code... Are you referring to System.Drawing.Color or System.Windows.Media.Color? The latter is used in WPF for example. I haven't seen anyone mention it yet, so just in case you were looking for it:

using System.Windows.Media;

Color color = (Color)ColorConverter.ConvertFromString("#FFDFD991");

If you would like to 'add' additional items to a page, you may want to create an array of maps. This is how I created an array of maps and then added results to it:

import { Product } from '../models/product';

products: Array<Product>;          // Initialize the array.

[...]

let i = 0;
this.service.products( i , (result) => {

    if ( i == 0 ) {
        // Create the first element of the array.
        this.products = Array(result);
    } else { 
        // Add to the array of maps.
        this.products.push(result);
    }

});

Where product.ts look like...

export class Product {
    id: number;
    [...]
}

Yes, Python3.6 installs PIP but it is unreachable as it is installed. There is no code which will invoke it as it is! I have been at it for more than a week and I read every single advice given, without success!

Finally, I tested going to the pip directory and upgrading the installed version:

root@bx:/usr/local/lib/python3.6/site-packages # python -m pip install --upgrade pip

That command created a PIP which now works properly from any location on my FreeBSD server!

Clearly, the tools installed simply do not work, as installed with Python3.6. The only way to run them is to invoke Python and the desired python files as you can see in the command issued. Once the update is called, however, the new PIP works globally without having to invoke Python3.6...

$('#registerform').submit(function(e) {
   e.preventDefault();
   $.ajax({
        type: 'POST',
        url: 'submit.php',
        data: $(this).serialize(),
        beforeSend: //do something
        complete: //do something
        success: //do something for example if the request response is success play your animation...
   });

})

The setting you are looking for is allow_url_fopen.

You have two ways of getting around it without changing php.ini, one of them is to use fsockopen(), and the other is to use cURL.

I recommend using cURL over file_get_contents() anyways, since it was built for this.

How about just adding a border the same color as the background using css? I'm new to this, so maybe there's a good reason not to, but it looked good when I tried it.

netcat (nc.exe) is the right tool. I have a feeling that any tool that does what you want it to do will have exactly the same problem with your antivirus software. Just flag this program as "OK" in your antivirus software (how you do this will depend on what type of antivirus software you use).

Of course you will also need to configure your sysadmin to accept that you're not trying to do anything illegal...

This class was compiled with a JDK more recent than the one used for execution.

The easiest is to install a more recent JRE on the computer where you execute the program. If you think you installed a recent one, check the JAVA_HOME and PATH environment variables.

Version 49 is java 1.5. That means the class was compiled with (or for) a JDK which is yet old. You probably tried to execute the class with JDK 1.4. You really should use one more recent (1.6 or 1.7, see java version history).

Use trim and val.

var value=$.trim($("#spa").val());

if(value.length>0)
{
 //do some stuffs. 
}

val() : return the value of the input.

trim(): will trim the white spaces.

Another solution would be to use Empty.

msdn extract:

Returns an empty IEnumerable that has the specified type argument.

IEnumerable<object> a = Enumerable.Empty<object>();

There is a thread on SO about it: Is it better to use Enumerable.Empty() as opposed to new List to initialize an IEnumerable?

If you use an empty array or empty list, those are objects and they are stored in memory. The Garbage Collector has to take care of them. If you are dealing with a high throughput application, it could be a noticeable impact.

Enumerable.Empty does not create an object per call thus putting less load on the GC.

You can use lock variables "a" and "b" and synchronize them for locking the "critical section" in reverse order. Eg. Notify "a" then Lock "b" ,"PRINT", Notify "b" then Lock "a".

Please refer the below the code :

public class EvenOdd {

    static int a = 0;

    public static void main(String[] args) {

        EvenOdd eo = new EvenOdd();

        A aobj = eo.new A();
        B bobj = eo.new B();

        aobj.a = Lock.lock1;
        aobj.b = Lock.lock2;

        bobj.a = Lock.lock2;
        bobj.b = Lock.lock1;

        Thread t1 = new Thread(aobj);
        Thread t2 = new Thread(bobj);

        t1.start();
        t2.start();
    }

    static class Lock {
        final static Object lock1 = new Object();
        final static Object lock2 = new Object();
    }

    class A implements Runnable {

        Object a;
        Object b;

        public void run() {
            while (EvenOdd.a < 10) {
                try {
                    System.out.println(++EvenOdd.a + " A ");
                    synchronized (a) {
                        a.notify();
                    }
                    synchronized (b) {
                        b.wait();
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    class B implements Runnable {

        Object a;
        Object b;

        public void run() {
            while (EvenOdd.a < 10) {

                try {
                    synchronized (b) {
                        b.wait();
                        System.out.println(++EvenOdd.a + " B ");
                    }
                    synchronized (a) {
                        a.notify();
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

OUTPUT :

Just adding an example that worked fine for me:

$sqldb = [string]($sqldir) + '\bin\MySQLInstanceConfig.exe'
$myarg = '-i ConnectionUsage=DSS Port=3311 ServiceName=MySQL RootPassword= ' + $rootpw
Start-Process $sqldb -ArgumentList $myarg

Since I'm disturbed by the verbosity of some of the new NUnit patterns, I use something like this to create code that is cleaner for me personally:

public void AssertBusinessRuleException(TestDelegate code, string expectedMessage)
{
    var ex = Assert.Throws<BusinessRuleException>(code);
    Assert.AreEqual(ex.Message, expectedMessage);
}

public void AssertException<T>(TestDelegate code, string expectedMessage) where T:Exception
{
    var ex = Assert.Throws<T>(code);
    Assert.AreEqual(ex.Message, expectedMessage);
}

The usage is then:

AssertBusinessRuleException(() => user.MakeUserActive(), "Actual exception message");

onBlur is when your focus is no longer on the field in question.

The onblur property returns the onBlur event handler code, if any, that exists on the current element.

onChange is when the value of the field changes.

Yes you need to convert to string in order to find the length.For example

var x=100;// type of x is number
var x=100+"";// now the type of x is string
document.write(x.length);//which would output 3.
