I follow all recommendations and all requirements. I install my self signed root CA on my iPhone. I make it trusted. I put certificate signed with this root CA on my local development server and I still get certificated error on safari iOS. Working on all other platforms.

This problem is caused by URLSession has two dataTask methods

open func dataTask(with request: URLRequest, completionHandler: @escaping (Data?, URLResponse?, Error?) -> Swift.Void) -> URLSessionDataTask
open func dataTask(with url: URL, completionHandler: @escaping (Data?, URLResponse?, Error?) -> Swift.Void) -> URLSessionDataTask

The first one has URLRequest as parameter, and the second one has URL as parameter, so we need to specify which type to call, for example, I want to call the second method

let task = URLSession.shared.dataTask(with: url! as URL) {
    data, response, error in
    // Handler
}

Currently you can use what docker offers now for a general and more complete cleaning:

docker system prune

To additionally remove any stopped containers and all unused images (not just dangling images), add the -a flag to the command:

docker system prune -a

If you are using Xcode 8.0 to 8.3.3 and swift 2.2 to 3.0

In my case need to change in URL http:// to https:// (if not working then try)

Add an App Transport Security Setting: Dictionary.
Add a NSAppTransportSecurity: Dictionary.
Add a NSExceptionDomains: Dictionary.
Add a yourdomain.com: Dictionary.  (Ex: stackoverflow.com)

Add Subkey named " NSIncludesSubdomains" as Boolean: YES
Add Subkey named " NSExceptionAllowsInsecureHTTPLoads" as Boolean: YES

In your responseJSON completion, you can get the status code from the response object, which has a type of NSHTTPURLResponse?:

if let response = res {
    var statusCode = response.statusCode
}

This will work regardless of whether the status code is in the error range. For more information, take a look at the NSHTTPURLResponse documentation.

For your other question, you can use the responseString function to get the raw response body. You can add this in addition to responseJSON and both will be called.

.responseJson { (req, res, json, error) in
   // existing code
}
.responseString { (_, _, body, _) in
   // body is a String? containing the response body
}

As already mentioned you have to use DateFormatter to format your Date objects. The easiest way to do it is creating a read-only computed property Date extension.

Read-Only Computed Properties

A computed property with a getter but no setter is known as a read-only computed property. A read-only computed property always returns a value, and can be accessed through dot syntax, but cannot be set to a different value.

Note:

You must declare computed properties—including read-only computed properties—as variable properties with the var keyword, because their value is not fixed. The let keyword is only used for constant properties, to indicate that their values cannot be changed once they are set as part of instance initialization.

You can simplify the declaration of a read-only computed property by removing the get keyword and its braces:

extension Formatter {
    static let date = DateFormatter()
}

extension Date {
    var europeanFormattedEn_US : String {
        Formatter.date.calendar = Calendar(identifier: .iso8601)
        Formatter.date.locale   = Locale(identifier: "en_US_POSIX")
        Formatter.date.timeZone = .current
        Formatter.date.dateFormat = "dd/M/yyyy, H:mm"
        return Formatter.date.string(from: self)
    }
}

To convert it back you can create another read-only computed property but as a string extension:

 extension String {
    var date: Date? {
        return Formatter.date.date(from: self)
    }
    func dateFormatted(with dateFormat: String = "dd/M/yyyy, H:mm", calendar: Calendar = Calendar(identifier: .iso8601), defaultDate: Date? = nil, locale: Locale = Locale(identifier: "en_US_POSIX"), timeZone: TimeZone = .current) -> Date? {
        Formatter.date.calendar = calendar
        Formatter.date.defaultDate = defaultDate ?? calendar.date(bySettingHour: 12, minute: 0, second: 0, of: Date())
        Formatter.date.locale = locale
        Formatter.date.timeZone = timeZone
        Formatter.date.dateFormat = dateFormat
        return Formatter.date.date(from: self)
    }
}

Usage:

let dateFormatted = Date().europeanFormattedEn_US         //"29/9/2018, 16:16"
if let date = dateFormatted.date {
    print(date.description(with:.current)) // Saturday, September 29, 2018 at 4:16:00 PM Brasilia Standard Time\n"\
    date.europeanFormattedEn_US                         // "29/9/2018, 16:27"
}

let dateString = "14/7/2016"
if let date = dateString.toDateFormatted(with: "dd/M/yyyy") {
    print(date.description(with: .current))
 // Thursday, July 14, 2016 at 12:00:00 PM Brasilia Standard Time\n"
}

I would highly recommend reading Apple's guides, and viewing the WWDC resources listed here: Internationalization and Localization Topics

To specifically answer your question, when you add a new language to your project, you get an opportunity to choose what InfoPlist files to include (if you have multiple targets, you'll have multiple Info plist files). All you need to do to get the following screen is hit the + under Localizations and choose a new language to add support for.

Once you've added, it will create the necessary string files in the appropriate lproj directories for the given language.

--EDIT--

Just to be clear, iOS will swap out the string for your Plist file based upon the user's currently selected language using the plist entry's key as the key in the localized strings file.

If anyone is getting this error while uploading files to a backend server, make sure the receiving server has a maximum content size that is allowable for your media. In my case, NGINX required a higher client_max_body_size. NGINX would reject the request before the uploading was done so no error code came back.

Probably the best way is this one here.

fileprivate func NSLocalizedString(_ key: String) -> String {
    return NSLocalizedString(key, comment: "")
}

and

import Foundation
extension String {
    static let Hello = NSLocalizedString("Hello")
    static let ThisApplicationIsCreated = NSLocalizedString("This application is created by the swifting.io team")
    static let OpsNoFeature = NSLocalizedString("Ops! It looks like this feature haven't been implemented yet :(!")
}

you can then use it like this

let message: String = .ThisApplicationIsCreated
print(message)

to me this is the best because

• The hardcoded strings are in one specific file, so the day you want to change it it's really easy
• Easier to use than manually typing the strings in your file every time
• genstrings will still work
• you can add more extensions, like one per view controller to keep things neat

I am calling the json on login button click

@IBAction func loginClicked(sender : AnyObject){

var request = NSMutableURLRequest(URL: NSURL(string: kLoginURL)) // Here, kLogin contains the Login API.


var session = NSURLSession.sharedSession()

request.HTTPMethod = "POST"

var err: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(self.criteriaDic(), options: nil, error: &err) // This Line fills the web service with required parameters.
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")

var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
 //   println("Response: \(response)")
var strData = NSString(data: data, encoding: NSUTF8StringEncoding)
println("Body: \(strData)")       
var err1: NSError?
var json2 = NSJSONSerialization.JSONObjectWithData(strData.dataUsingEncoding(NSUTF8StringEncoding), options: .MutableLeaves, error:&err1 ) as NSDictionary

println("json2 :\(json2)")

if(err) {
    println(err!.localizedDescription)
}
else {
    var success = json2["success"] as? Int
    println("Succes: \(success)")
}
})

task.resume()

}

Here, I have made a seperate dictionary for the parameters.

var params = ["format":"json", "MobileType":"IOS","MIN":"f8d16d98ad12acdbbe1de647414495ec","UserName":emailTxtField.text,"PWD":passwordTxtField.text,"SigninVia":"SH"]as NSDictionary
     return params
}

Suppose we want to pass three values(u1,u2,u3) from say 'show.jsp' to another page say 'display.jsp' Make three hidden text boxes and a button that is click automatically(using javascript). //Code to written in 'show.jsp'

<body>
<form action="display.jsp" method="post">
 <input type="hidden" name="u1" value="<%=u1%>"/>
 <input type="hidden" name="u2" value="<%=u2%>" />
 <input type="hidden" name="u3" value="<%=u3%>" />
 <button type="hidden" id="qq" value="Login" style="display: none;"></button>
</form>
  <script type="text/javascript">
     document.getElementById("qq").click();
  </script>
</body>

// Code to be written in 'display.jsp'

 <% String u1 = request.getParameter("u1").toString();
    String u2 = request.getParameter("u2").toString();
    String u3 = request.getParameter("u3").toString();
 %>

If you want to use these variables of servlets in javascript then simply write

<script type="text/javascript">
 var a=<%=u1%>;
</script>

Hope it helps :)

HTTP response 0 is not standard HTTP response. But it indicates that client could not connect with server and hence forth time out happened.

On the server side, I added:

header('Content-type: application/json');

into my .php code and this also fixed the problem.

Nothing is seen. The page is empty and white.

Also known as the White Page Of Death or White Screen Of Death. This happens when error reporting is turned off and a fatal error (often syntax error) occurred.

If you have error logging enabled, you will find the concrete error message in your error log. This will usually be in a file called "php_errors.log", either in a central location (e.g. /var/log/apache2 on many Linux environments) or in the directory of the script itself (sometimes used in a shared hosting environment).

Sometimes it might be more straightforward to temporarily enable the display of errors. The white page will then display the error message. Take care because these errors are visible to everybody visiting the website.

This can be easily done by adding at the top of the script the following PHP code:

ini_set('display_errors', 1); error_reporting(~0);

The code will turn on the display of errors and set reporting to the highest level.

Since the ini_set() is executed at runtime it has no effects on parsing/syntax errors. Those errors will appear in the log. If you want to display them in the output as well (e.g. in a browser) you have to set the display_startup_errors directive to true. Do this either in the php.ini or in a .htaccess or by any other method that affects the configuration before runtime.

You can use the same methods to set the log_errors and error_log directives to choose your own log file location.

Looking in the log or using the display, you will get a much better error message and the line of code where your script comes to halt.

The question is: How do you define if a week is in 2012 or in 2013? Your supposition, I guess, is that since 6 days of the week are in 2013, this week should be marked as the first week of 2013.

Not sure if this is the right way to go. That week started on 2012 (On monday 31th Dec), so it should be marked as the last week of 2012, therefore it should be the 53rd of 2012. The first week of 2013 should start on monday the 7th.

Now, you can handle the particular case of edge weeks (first and last week of the year) using the day of week information. It all depends on your logic.

My problem was simply that I was signing with the Xcode-managed wildcard provisioning profile.

After I created an app-specific profile (and downloaded it, double-clicked it, and ensured my Build Settings referred to it), I successfully received an APNS device token.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

c# 7.0 lets you do this:

  var tupleList = new List<(int, string)>
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

If you don't need a List, but just an array, you can do:

  var tupleList = new(int, string)[]
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

And if you don't like "Item1" and "Item2", you can do:

  var tupleList = new List<(int Index, string Name)>
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

or for an array:

  var tupleList = new (int Index, string Name)[]
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

which lets you do: tupleList[0].Index and tupleList[0].Name

Framework 4.6.2 and below

You must install System.ValueTuple from the Nuget Package Manager.

Framework 4.7 and above

It is built into the framework. Do not install System.ValueTuple. In fact, remove it and delete it from the bin directory.

note: In real life, I wouldn't be able to choose between cow, chickens or airplane. I would be really torn.

Another way would be to encode the quotes using htmlspecialchars:

$json_array = array(
    'title' => 'Example string\'s with "special" characters'
);

$json_decode = htmlspecialchars(json_encode($json_array), ENT_QUOTES, 'UTF-8');

How about writing a custom attribute:

public class LocalizedDisplayNameAttribute: DisplayNameAttribute
{
    public LocalizedDisplayNameAttribute(string resourceId) 
        : base(GetMessageFromResource(resourceId))
    { }

    private static string GetMessageFromResource(string resourceId)
    {
        // TODO: Return the string from the resource file
    }
}

which could be used like this:

public class MyModel 
{
    [Required]
    [LocalizedDisplayName("labelForName")]
    public string Name { get; set; }
}

For Swift you can override the main.swift file and set the UserDefaults string there before you app runs. This way you do not have to restart the App to see the desired effect.

import Foundation
import UIKit

// Your initialisation code here
let langCultureCode: String = "LANGUAGE_CODE"

UserDefaults.standard.set([langCultureCode], forKey: "AppleLanguages")
UserDefaults.standard.synchronize()

UIApplicationMain(CommandLine.argc, CommandLine.unsafeArgv, nil, NSStringFromClass(AppDelegate.self))

paired together with the removal of @UIApplicationMain in your AppDelegate.swift file.

I would do it in the Initialize event of the controller like this...

    protected override void Initialize(System.Web.Routing.RequestContext requestContext)
    {
        base.Initialize(requestContext);

        const string culture = "en-US";
        CultureInfo ci = CultureInfo.GetCultureInfo(culture);

        Thread.CurrentThread.CurrentCulture = ci;
        Thread.CurrentThread.CurrentUICulture = ci;
    }

7 years passed and...
actually there's this new SQL Server 2016 feature that does exactly what you need.
It is called AT TIME ZONE and it converts date to a specified time zone considering DST (daylight saving time) changes.
More info here: https://msdn.microsoft.com/en-us/library/mt612795.aspx

Apparently in Android 2.2 there is a bug with SimpleDateFormat.

In order to use month names you have to define them yourself in your resources:

<string-array name="month_names">
    <item>January</item>
    <item>February</item>
    <item>March</item>
    <item>April</item>
    <item>May</item>
    <item>June</item>
    <item>July</item>
    <item>August</item>
    <item>September</item>
    <item>October</item>
    <item>November</item>
    <item>December</item>
</string-array>

And then use them in your code like this:

/**
 * Get the month name of a Date. e.g. January for the Date 2011-01-01
 * 
 * @param date
 * @return e.g. "January"
 */
public static String getMonthName(Context context, Date date) {

    /*
     * Android 2.2 has a bug in SimpleDateFormat. Can't use "MMMM" for
     * getting the Month name for the given Locale. Thus relying on own
     * values from string resources
     */

    String result = "";

    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    int month = cal.get(Calendar.MONTH);

    try {
        result = context.getResources().getStringArray(R.array.month_names)[month];
    } catch (ArrayIndexOutOfBoundsException e) {
        result = Integer.toString(month);
    }

    return result;
}

Looking at your question its clear that you just want to send the date range to your backend for further post processing.

I am assuming you are conforming to the standard data guidelines which expect the data to be in a particular format. For example, I use ODATA which is a RESTfull API which expects date time objects to be in the format:-

YYYY-MM-DDT00:00:00.

That can be easily achieved via the snippet posted below(Please change the format as per your requirement).

var mydate;//assuming this is my date object which I want to expose var UTCDateStr = mydate.getUTCFullYear() + "-" + mydate.getUTCMonth() + "-" + mydate.getUTCDate() + "T00:00:00";

If on the other hand, you are in my situation wherein you have received a date from your backend, and the browser converts that to your local date. You on the other hand are interested in the UTC date then you can perform the following:-

var mydate;//assuming this is my date object which I want to expose var UTCDate = new Date(mydate);/*create a copy of your date object. Only needed if you for some reason need the original local date*/ UTCDate.setTime(UTCDate.getTime() + UTCDate.getTimezoneOffset() * 60 * 1000);

The code snippet above basically adds/subtracts the time added/subtracted by the browser based on the timezone.

For example if I am in EST(GMT-5) and my Service returns a date time object = Wed Aug 17 2016 00:00:00 GMT-0500 my browser automatically subtracts the timezone offset(5hrs) to get my local time. So if I try to fetch the time I get Wed Aug 16 2016 19:00:00 GMT-0500. This causes a lot of problems. There are a lot of libraries out there which will definitely make this easier but I wanted to share the pure JS approach.

For more info please have a look at: http://praveenlobo.com/blog/how-to-convert-javascript-local-date-to-utc-and-utc-to-local-date/ where in I got my inspiration.

Hope this helps!

Martin's solution is very similar to mine, however how would you handle a default descriptions when the desired translation isn't found ?

Would that require an IFNULL() and another SELECT statement for each field ?

The default translation would be stored in the same table, where a flag like "isDefault" indicates wether that description is the default description in case none has been found for the current language.

This article suggests the following properties of the browser's navigator object:

• navigator.language (Netscape - Browser Localization)
• navigator.browserLanguage (IE-Specific - Browser Localized Language)
• navigator.systemLanguage (IE-Specific - Windows OS - Localized Language)
• navigator.userLanguage

Roll these into a javascript function and you should be able to guess the right language, in most circumstances. Be sure to degrade gracefully, so have a div containing your language choice links, so that if there is no javascript or the method doesn't work, the user can still decide. If it does work, just hide the div.

The only problem with doing this on the client side is that either you serve up all the languages to the client, or you have to wait until the script has run and detected the language before requesting the right version. Perhaps serving up the most popular language version as a default would irritate the fewest people.

Edit: I'd second Ivan's cookie suggestion, but make sure the user can always change the language later; not everyone prefers the language their browser defaults to.

I figured out the demo and implemented it the following way:

$.datepicker.setDefaults(
  $.extend(
    {'dateFormat':'dd-mm-yy'},
    $.datepicker.regional['nl']
  )
);

I needed to set the default for the dateformat too ...

You can do it like this:

$str = "abc-123-xyz-789";
$arr = explode('-', $str);
$last = array_pop( $arr );
echo $last; //echoes 789

How about

Select I.Fee
From Item I
WHERE  (days(GETDATE()) - days(I.DateCreated) < 365)

Firebug debug process

I found Serge's answer to be very promising, but I also encountered performance issues with it as-written. However, when I restructured it to use temporary tables and not include double CTE tables, the performance went from 1 minute 40 seconds to sub-second for 1000 combined records. Here it is for anyone who needs to do this without FOR XML on older versions of SQL Server:

DECLARE @STRUCTURED_VALUES TABLE (
     ID                 INT
    ,VALUE              VARCHAR(MAX) NULL
    ,VALUENUMBER        BIGINT
    ,VALUECOUNT         INT
);

INSERT INTO @STRUCTURED_VALUES
SELECT   ID
        ,VALUE
        ,ROW_NUMBER() OVER (PARTITION BY ID ORDER BY VALUE) AS VALUENUMBER
        ,COUNT(*) OVER (PARTITION BY ID)    AS VALUECOUNT
FROM    RAW_VALUES_TABLE;

WITH CTE AS (
    SELECT   SV.ID
            ,SV.VALUE
            ,SV.VALUENUMBER
            ,SV.VALUECOUNT
    FROM    @STRUCTURED_VALUES SV
    WHERE   VALUENUMBER = 1

    UNION ALL

    SELECT   SV.ID
            ,CTE.VALUE + ' ' + SV.VALUE AS VALUE
            ,SV.VALUENUMBER
            ,SV.VALUECOUNT
    FROM    @STRUCTURED_VALUES SV
    JOIN    CTE 
        ON  SV.ID = CTE.ID
        AND SV.VALUENUMBER = CTE.VALUENUMBER + 1

)
SELECT   ID
        ,VALUE
FROM    CTE
WHERE   VALUENUMBER = VALUECOUNT
ORDER BY ID
;

The reason it is only a suggestion is that you could quite easily write a print function that ignored the options value. The built-in printing and formatting functions do use the options value as a default.

As to the second question, since R uses finite precision arithmetic, your answers aren't accurate beyond 15 or 16 decimal places, so in general, more aren't required. The gmp and rcdd packages deal with multiple precision arithmetic (via an interace to the gmp library), but this is mostly related to big integers rather than more decimal places for your doubles.

Mathematica or Maple will allow you to give as many decimal places as your heart desires.

EDIT:
It might be useful to think about the difference between decimal places and significant figures. If you are doing statistical tests that rely on differences beyond the 15th significant figure, then your analysis is almost certainly junk.

On the other hand, if you are just dealing with very small numbers, that is less of a problem, since R can handle number as small as .Machine$double.xmin (usually 2e-308).

Compare these two analyses.

x1 <- rnorm(50, 1, 1e-15)
y1 <- rnorm(50, 1 + 1e-15, 1e-15)
t.test(x1, y1)  #Should throw an error

x2 <- rnorm(50, 0, 1e-15)
y2 <- rnorm(50, 1e-15, 1e-15)
t.test(x2, y2)  #ok

In the first case, differences between numbers only occur after many significant figures, so the data are "nearly constant". In the second case, Although the size of the differences between numbers are the same, compared to the magnitude of the numbers themselves they are large.

As mentioned by e3bo, you can use multiple-precision floating point numbers using the Rmpfr package.

mpfr("3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825")

These are slower and more memory intensive to use than regular (double precision) numeric vectors, but can be useful if you have a poorly conditioned problem or unstable algorithm.

I tried the solution of Oskar (and many others) but for me it finaly only worked with:

jQuery(function($){
   // Your jQuery code here, using the $
});

See: https://learn.jquery.com/using-jquery-core/avoid-conflicts-other-libraries/

The params parameter modifier gives callers a shortcut syntax for passing multiple arguments to a method. There are two ways to call a method with a params parameter:

1) Calling with an array of the parameter type, in which case the params keyword has no effect and the array is passed directly to the method:

object[] array = new[] { "1", "2" };

// Foo receives the 'array' argument directly.
Foo( array );

2) Or, calling with an extended list of arguments, in which case the compiler will automatically wrap the list of arguments in a temporary array and pass that to the method:

// Foo receives a temporary array containing the list of arguments.
Foo( "1", "2" );

// This is equivalent to:
object[] temp = new[] { "1", "2" );
Foo( temp );

In order to pass in an object array to a method with a "params object[]" parameter, you can either:

1) Create a wrapper array manually and pass that directly to the method, as mentioned by lassevk:

Foo( new object[] { array } );  // Equivalent to calling convention 1.

2) Or, cast the argument to object, as mentioned by Adam, in which case the compiler will create the wrapper array for you:

Foo( (object)array );  // Equivalent to calling convention 2.

However, if the goal of the method is to process multiple object arrays, it may be easier to declare it with an explicit "params object[][]" parameter. This would allow you to pass multiple arrays as arguments:

void Foo( params object[][] arrays ) {
  foreach( object[] array in arrays ) {
    // process array
  }
}

...
Foo( new[] { "1", "2" }, new[] { "3", "4" } );

// Equivalent to:
object[][] arrays = new[] {
  new[] { "1", "2" },
  new[] { "3", "4" }
};
Foo( arrays );

Edit: Raymond Chen describes this behavior and how it relates to the C# specification in a new post.

I found this answer and it almost fit my needs. Thanks to SwDevMan81 for the class. I have modified it to allow suppression and resumation of individual methods, and I thought I'd post it here.

// This class allows you to selectively suppress event handlers for controls.  You instantiate
// the suppressor object with the control, and after that you can use it to suppress all events
// or a single event.  If you try to suppress an event which has already been suppressed
// it will be ignored.  Same with resuming; you can resume all events which were suppressed,
// or a single one.  If you try to resume an un-suppressed event handler, it will be ignored.

//cEventSuppressor _supButton1 = null;
//private cEventSuppressor SupButton1 {
//    get {
//        if (_supButton1 == null) {
//            _supButton1 = new cEventSuppressor(this.button1);
//        }
//        return _supButton1;
//    }
//}
//private void button1_Click(object sender, EventArgs e) {
//    MessageBox.Show("Clicked!");
//}

//private void button2_Click(object sender, EventArgs e) {
//    SupButton1.Suppress("button1_Click");
//}

//private void button3_Click(object sender, EventArgs e) {
//    SupButton1.Resume("button1_Click");
//}

You can also use rcParams to change the font family globally.

 import matplotlib.pyplot as plt
 plt.rcParams["font.family"] = "cursive"
 # This will change to your computer's default cursive font

The list of matplotlib's font family arguments is here.

make sure your app is live on developer.facebook.com

This green circle is indicating the app is live

If it is not then follow this two steps for make your app live

Step 1 Go to your application -> setting => and add Contact Email and apply save Changes

Setp 2 Then goto App Review option and make sure this toggle is Yes i added a screen shot

First execute the below command:

sp_who2

After that execute the below command with SPID, which you got from above command:

KILL {SPID value}

I landed here because I was looking for something like that too. In my case, I was copying the data from a set of staging tables with many columns into one table while also assigning row ids to the target table. Here is a variant of the above approaches that I used. I added the serial column at the end of my target table. That way I don't have to have a placeholder for it in the Insert statement. Then a simple select * into the target table auto populated this column. Here are the two SQL statements that I used on PostgreSQL 9.6.4.

ALTER TABLE target ADD COLUMN some_column SERIAL;
INSERT INTO target SELECT * from source;

I will add my answer since I don't use any of the other answers provided.

With the Support Library v7, all the styles are actually already defined and ready to use, for the standard buttons, all of these styles are available:

style="@style/Widget.AppCompat.Button"
style="@style/Widget.AppCompat.Button.Colored"
style="@style/Widget.AppCompat.Button.Borderless"
style="@style/Widget.AppCompat.Button.Borderless.Colored"

Widget.AppCompat.Button:

Widget.AppCompat.Button.Colored:

Widget.AppCompat.Button.Borderless

Widget.AppCompat.Button.Borderless.Colored:

To answer the question, the style to use is therefore

<Button style="@style/Widget.AppCompat.Button.Colored"
.......
.......
.......
android:text="Button"/>

How to change the color

For the whole app:

The color of all the UI controls (not only buttons, but also floating action buttons, checkboxes etc.) is managed by the attribute colorAccent as explained here. You can modify this style and apply your own color in your theme definition:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    ...
    <item name="colorAccent">@color/Orange</item>
</style>

For a specific button:

If you need to change the style of a specific button, you can define a new style, inheriting one of the parent styles described above. In the example below I just changed the background and font colors:

<style name="AppTheme.Button" parent="Widget.AppCompat.Button.Colored">
    <item name="colorButtonNormal">@color/Red</item>
    <item name="android:textColor">@color/White</item>
</style>

Then you just need to apply this new style on the button with:

android:theme="@style/AppTheme.Button"

To set a default button design in a layout, add this line to the styles.xml theme:

<item name="buttonStyle">@style/btn</item>

where @style/btn is your button theme. This sets the button style for all the buttons in a layout with a specific theme

You can use chmod with the X mode letter (the capital X) to set the executable flag only for directories.

In the example below the executable flag is cleared and then set for all directories recursively:

~$ mkdir foo
~$ mkdir foo/bar
~$ mkdir foo/baz
~$ touch foo/x
~$ touch foo/y

~$ chmod -R go-X foo 
~$ ls -l foo
total 8
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 bar
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 y

~$ chmod -R go+X foo 
~$ ls -l foo
total 8
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 bar
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 y

A bit of explaination:

• chmod -x foo - clear the eXecutable flag for foo
• chmod +x foo - set the eXecutable flag for foo
• chmod go+x foo - same as above, but set the flag only for Group and Other users, don't touch the User (owner) permission
• chmod go+X foo - same as above, but apply only to directories, don't touch files
• chmod -R go+X foo - same as above, but do this Recursively for all subdirectories of foo

I encountered the same error while using SpringBoot 2.1.4, along with Spring Security 5 (I believe). After one day of trying everything that Google had to offer, I discovered the cause of error in my case. I had a setup of micro-services, with the Auth server being different from the Resource Server. I had the following lines in my application.yml which prevented 'auto-configuration' despite of having included dependencies spring-boot-starter-security, spring-security-oauth2 and spring-security-jwt. I had included the following in the properties (during development) which caused the error.

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Commenting it out solved it for me.

#spring:
#  autoconfigure:
#    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Hope, it helps someone.

Code for one liner isFlashExists variable:

<script type='text/javascript'
    src='//ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js'> </script>

<script type='text/javascript'>
   var isFlashExists = swfobject.hasFlashPlayerVersion('1') ? true : false ;
   if (isFlashExists) {
    alert ('flash exists');
   } else {
    alert ('NO flash');
   }
</script>

Note that there is an alternative like this: swfobject.getFlashPlayerVersion();

If you are using maven, you can use this command mvn tomcat:run, but first you add in your pom.xml this structure into build tag, just like this:

<build>
    <finalName>mvn-webapp-test</finalName>
      <plugins>
          <plugin>
              <groupId>org.apache.maven.plugins</groupId>
              <artifactId>maven-compiler-plugin</artifactId>
              <version>${maven.compiler.plugin.version}</version>
              <configuration>
                  <source>1.6</source>
                  <target>1.6</target>
              </configuration>
          </plugin>
      </plugins>
  </build>

I'll just post the code to do this using the fluent API mapping.

public class User {
    public int UserID { get; set; }
    public string Username { get; set; }
    public string Password { get; set; }

    public ICollection<UserEmail> UserEmails { get; set; }
}

public class Email {
    public int EmailID { get; set; }
    public string Address { get; set; }

    public ICollection<UserEmail> UserEmails { get; set; }
}

public class UserEmail {
    public int UserID { get; set; }
    public int EmailID { get; set; }
    public bool IsPrimary { get; set; }
}

On your DbContext derived class you could do this:

public class MyContext : DbContext {
    protected override void OnModelCreating(DbModelBuilder builder) {
        // Primary keys
        builder.Entity<User>().HasKey(q => q.UserID);
        builder.Entity<Email>().HasKey(q => q.EmailID);
        builder.Entity<UserEmail>().HasKey(q => 
            new { 
                q.UserID, q.EmailID
            });

        // Relationships
        builder.Entity<UserEmail>()
            .HasRequired(t => t.Email)
            .WithMany(t => t.UserEmails)
            .HasForeignKey(t => t.EmailID)

        builder.Entity<UserEmail>()
            .HasRequired(t => t.User)
            .WithMany(t => t.UserEmails)
            .HasForeignKey(t => t.UserID)
    }
}

It has the same effect as the accepted answer, with a different approach, which is no better nor worse.

create environment variable like in the screenshot and make sure to replace with your sdk path in my case it was C:\Users\zeesh\AppData\Local\Android\sdk replace zeesh with your username and make sure to restart android studio to take effect.

Simply this line of code will disable all input elements

$('#yourdiv *').prop('disabled', true);

This post is pretty old, but for thoses who got here in 2016. None of the example here worked for me. Using keyup instead of autocompletechange did the job. Using jquery-ui 10.4

$("#CompanyList").on("keyup", function (event, ui) {
    console.log($(this).val());
});

Hope this help!

If you want to keep all the style but change few details, you can use the default style defined on the Android and change what you want

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:textColor="@android:color/background_light"
    android:paddingStart="?android:attr/listPreferredItemPaddingStart"
    android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
    android:background="?android:attr/activatedBackgroundIndicator"
    android:minHeight="?android:attr/listPreferredItemHeightSmall" />

Then set the adapter using:

setListAdapter(new ArrayAdapter<String>(getApplicationContext(),
            R.layout.list_item_custom, mStringList));

Source: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/layout/simple_list_item_activated_1.xml

Just found a way how to do it:

Just add the paths to the /app/start/global.php

ClassLoader::addDirectories(array(

    app_path().'/commands',
    app_path().'/controllers',
    app_path().'/controllers/product',
    app_path().'/models',
    app_path().'/database/seeds',

));

C:\\Users\\expoperialed\\Desktop\\Python This syntax worked for me.

There is an inspiration here. Just utilize shell regex or git regex.

git checkout commit_id */*.bat  # *.bat in 1-depth subdir exclude current dir, shell regex  
git checkout commit_id '*.bat'  # *.bat in all subdir include current dir, git regex

Use quotation to escape shell regex interpretation and pass wildcards to git.

The first one is not recursive, only files in 1-depth subdir. But the second one is recursive.

As for your situation, the following may be enough.

git checkout master */*/wp-content/*/*
git checkout master '*/wp-content/*'

Just hack the lines as required.

Yes, you can use the *args (splat) syntax:

function_that_needs_strings(*my_list)

where my_list can be any iterable; Python will loop over the given object and use each element as a separate argument to the function.

See the call expression documentation.

There is a keyword-parameter equivalent as well, using two stars:

kwargs = {'foo': 'bar', 'spam': 'ham'}
f(**kwargs)

and there is equivalent syntax for specifying catch-all arguments in a function signature:

def func(*args, **kw):
    # args now holds positional arguments, kw keyword arguments

You can also use regions. See https://www.myandroidsolutions.com/2014/06/21/android-studio-intellij-idea-code-regions/

Select a block of code, then press Code > Surround With... (Ctrl + Alt + T) and select "region...endregion Comments" (2).

The Random class of Java located in the java.util package will serve your purpose better. It has some nextInt() methods that return an integer. The one taking an int argument will generate a number between 0 and that int, the latter not inclusive.

1. Open xls file with a hex editor.
2. Search for DPB
3. Replace DPB to DPx
4. Save file.
5. Open file in Excel.
6. Click "Yes" if you get any message box.
7. Set new password from VBA Project Properties.
8. Close and open again file, then type your new password to unprotect.

Check http://blog.getspool.com/396/best-vba-password-recovery-cracker-tool-remove/

You can simply use:

ps -o args= -f -p ProcessPid

You are very close; currently you compare the row[2] with integer 0, make the comparison with the string "0". When you read the data from a file, it is a string and not an integer, so that is why your integer check fails currently:

row[2]!="0":

Also, you can use the with keyword to make the current code slightly more pythonic so that the lines in your code are reduced and you can omit the .close statements:

import csv
with open('first.csv', 'rb') as inp, open('first_edit.csv', 'wb') as out:
    writer = csv.writer(out)
    for row in csv.reader(inp):
        if row[2] != "0":
            writer.writerow(row)

Note that input is a Python builtin, so I've used another variable name instead.

Edit: The values in your csv file's rows are comma and space separated; In a normal csv, they would be simply comma separated and a check against "0" would work, so you can either use strip(row[2]) != 0, or check against " 0".

The better solution would be to correct the csv format, but in case you want to persist with the current one, the following will work with your given csv file format:

$ cat test.py 
import csv
with open('first.csv', 'rb') as inp, open('first_edit.csv', 'wb') as out:
    writer = csv.writer(out)
    for row in csv.reader(inp):
        if row[2] != " 0":
            writer.writerow(row)
$ cat first.csv 
6.5, 5.4, 0, 320
6.5, 5.4, 1, 320
$ python test.py 
$ cat first_edit.csv 
6.5, 5.4, 1, 320

Another reason why this exception occurs is if you call the configure method twice on a Configuration or AnnotatedConfiguration object like this -

AnnotationConfiguration config = new AnnotationConfiguration();
config.addAnnotatedClass(MyClass.class);
//Use this if config files are in src folder
config.configure();
//Use this if config files are in a subfolder of src, such as "resources"
config.configure("/resources/hibernate.cfg.xml");

Btw, this project structure is inside eclipse.

Try Jedi! There's a Vim plugin at https://github.com/davidhalter/jedi-vim.

It works just much better than anything else for Python in Vim. It even has support for renaming, goto, etc. The best part is probably that it really tries to understand your code (decorators, generators, etc. Just look at the feature list).

Just try:

http://ipaddressofpcwhichhasdatabase:portnumber(80 by default)/filename.extension

/^\d+(?:, ?\d+)*$/

be aware that this is dangerous:

WHERE `column` LIKE '%{$needle}%'

do first:

$needle = mysql_real_escape_string($needle);

so it will prevent possible attacks.

A faster method

If you are doing this repeatedly, for example to pad values in an array, and performance is a factor, the following approach can give you nearly a 100x advantage in speed (jsPerf) over other solution that are currently discussed on the inter webs. The basic idea is that you are providing the pad function with a fully padded empty string to use as a buffer. The pad function just appends to string to be added to this pre-padded string (one string concat) and then slices or trims the result to the desired length.

function pad(pad, str, padLeft) {
  if (typeof str === 'undefined') 
    return pad;
  if (padLeft) {
    return (pad + str).slice(-pad.length);
  } else {
    return (str + pad).substring(0, pad.length);
  }
}

For example, to zero pad a number to a length of 10 digits,

pad('0000000000',123,true);

To pad a string with whitespace, so the entire string is 255 characters,

var padding = Array(256).join(' '), // make a string of 255 spaces
pad(padding,123,true);

Performance Test

See the jsPerf test here.

And this is faster than ES6 string.repeat by 2x as well, as shown by the revised JsPerf here

Please note that jsPerf is no longer online

Please note that the jsPerf site that we originally used to benchmark the various methods is no longer online. Unfortunately, this means we can't get to those test results. Sad but true.

Use immediate children selector >:

$('#tblOne > tbody  > tr')

Description: Selects all direct child elements specified by "child" of elements specified by "parent".

in case someone got stuck with this and none of the answers above worked, below is what worked for me. Hope it helps.

var oldString = "\\r|\\n";

// None of these worked for me
// var newString = oldString(@"\\", @"\");
// var newString = oldString.Replace("\\\\", "\\");
// var newString = oldString.Replace("\\u5b89", "\u5b89");
// var newString = Regex.Replace(oldString , @"\\", @"\");

// This is what worked
var newString = Regex.Unescape(oldString);
// newString is now "\r|\n"

I think is for prevent the browser's HTML parser from interpreting the <script>, and mainly the </script> as the closing tag of the actual script, however I don't think that using document.write is a excellent idea for evaluating script blocks, why don't use the DOM...

var newScript = document.createElement("script");
...

Chrome can run as root (remember to use gksu when doing so) so long as you provide it with a profile directory.

Rather than type in the profile directory every time you want to run it, create a new bash file (I'd name it something like start-chrome.sh)

#/bin/bash
google-chrome --user-data-dir="/root/chrome-profile/"

Rember to call that script with root privelages!

$ gksu /root/start-chrome.sh

If you want to do this in RegexBuddy, there are two ways to get a list of all lines not matching a regex.

On the toolbar on the Test panel, set the test scope to "Line by line". When you do that, an item List All Lines without Matches will appear under the List All button on the same toolbar. (If you don't see the List All button, click the Match button in the main toolbar.)

On the GREP panel, you can turn on the "line-based" and the "invert results" checkboxes to get a list of non-matching lines in the files you're grepping through.

With Eloquent its very easy to retrieve relational data. Checkout the following example with your scenario in Laravel 5.

We have three models:

1) Article (belongs to user and category)

2) Category (has many articles)

3) User (has many articles)

1) Article.php

<?php

namespace App\Models;
 use Eloquent;

class Article extends Eloquent{

    protected $table = 'articles';

    public function user()
    {
        return $this->belongsTo('App\Models\User');
    }

    public function category()
    {
        return $this->belongsTo('App\Models\Category');
    }

}

2) Category.php

<?php

namespace App\Models;

use Eloquent;

class Category extends Eloquent
{
    protected $table = "categories";

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

3) User.php

<?php

namespace App\Models;
use Eloquent;

class User extends Eloquent
{
    protected $table = 'users';

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

You need to understand your database relation and setup in models. User has many articles. Category has many articles. Articles belong to user and category. Once you setup the relationships in Laravel, it becomes easy to retrieve the related information.

For example, if you want to retrieve an article by using the user and category, you would need to write:

$article = \App\Models\Article::with(['user','category'])->first();

and you can use this like so:

//retrieve user name 
$article->user->user_name  

//retrieve category name 
$article->category->category_name

In another case, you might need to retrieve all the articles within a category, or retrieve all of a specific user`s articles. You can write it like this:

$categories = \App\Models\Category::with('articles')->get();

$users = \App\Models\Category::with('users')->get();

You can learn more at http://laravel.com/docs/5.0/eloquent

ALL of these solutions on this page are harder than they need to be.

Do this

RegName = "SomE StRing That you wAnt ConvErTed";
NameLength = RegName.Size();
for (int forLoop = 0; forLoop < NameLength; ++forLoop)
{
     RegName[forLoop] = tolower(RegName[forLoop]);
}

RegName is your string. Get your string size don't use string.size() as your actual tester, very messy and can cause issues. then. the most basic for loop.

remember string size returns the delimiter too so use < and not <= in your loop test.

output will be: some string that you want converted

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

In my (I have LAMP installed) /etc/mysql/my.cnf file I found following, commented lines in [mysqld] section:

general_log_file        = /var/log/mysql/mysql.log
general_log             = 1

I had to open this file as superuser, with terminal:

sudo geany /etc/mysql/my.cnf

(I prefer to use Geany instead of gedit or VI, it doesn't matter)

I just uncommented them & save the file then restart MySQL with

sudo service MySQL restart

Run several queries, open the above file (/var/log/mysql/mysql.log) and the log was there :)

If you already committed the changes than you would have to revert changes.

If you didn't commit yet, just do a clean checkout git checkout .

If you cannot install aditional applications, then you can telnet (you will need to install this feature for your windows 7 by following this) the remote server:

TELNET server_name 80

followed by:

HEAD /virtual/directory/file.ext

or

GET /virtual/directory/file.ext

depending on if you want just the header (HEAD) or the full contents (GET)

The ubuntu package name is qt5-default, not qt.

As long as the macros in question are in the same workbook and you verify the names exist, you can call those macros from any other module by name, not by module.

So if in Module1 you had two macros Macro1 and Macro2 and in Module2 you had Macro3 and Macro 4, then in another macro you could call them all:

Sub MasterMacro()
    Call Macro1
    Call Macro2
    Call Macro3
    Call Macro4
End Sub

My code was broken because I was using a deprecated technique. It used to be this:

video.src = window.URL.createObjectURL(localMediaStream);
video.play();

Then I replaced that with this:

video.srcObject = localMediaStream;
video.play();

That worked beautifully.

EDIT: Recently localMediaStream has been deprecated and replaced with MediaStream. The latest code looks like this:

video.srcObject = new MediaStream();

1. Serializable

@see http://docs.oracle.com/javase/7/docs/api/java/io/Serializable.html

Interface of what?

• is a standard Java interface

Speed

• slower than Parcelable

2. Parcelable

@see http://developer.android.com/reference/android/os/Parcelable.html

Interface of what?

• is android.os interface
  • which means Google developped Parcelable for better performance on android

Speed

• faster ( because it is optimized for usage on android development)

> In Conclusion

Be aware that Serializable is a standard Java interface, and Parcelable is for Android Development

Try keydown instead of keypress.

The keyboard events occur in this order: keydown, keyup, keypress

The problem with backspace probably is, that the browser will navigate back on keyup and thus your page will not see the keypress event.

You need to use a graphics library. Put this in your preamble:

\usepackage{graphicx}

You can then add images like this:

\begin{figure}[ht!]
\centering
\includegraphics[width=90mm]{fixed_dome1.jpg}
\caption{A simple caption \label{overflow}}
\end{figure}

This is the basic template I use in my documents. The position and size should be tweaked for your needs. Refer to the guide below for more information on what parameters to use in \figure and \includegraphics. You can then refer to the image in your text using the label you gave in the figure:

And here we see figure \ref{overflow}.

Read this guide here for a more detailed instruction: http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions

I use zsh on a Mac, and I can post multi-line commit messages within double quotes ("). Basically I keep typing and pressing return for new lines, but the message isn't sent to Git until I close the quotes and return.

overflow-x: auto;
overflow-y : hidden;

Apply the styling above to the parent div.

The "input" tag doesn't support rows and cols attributes. This is why the best alternative is to use a textarea with rows and cols attributes. You can still add a "name" attribute and also there is a useful "wrap" attribute which can serve pretty well in various situations.

In InnoDB, with a limit on table size of 64 terabytes and a MySQL row-size limit of 65,535 there can be 1,073,741,824 rows. That would be minimum number of records utilizing maximum row-size limit. However, more records can be added if the row size is smaller .

There's no (safe) way to pause execution. You can, however, do something like this using setTimeout:

function writeNext(i)
{
    document.write(i);

    if(i == 5)
        return;

    setTimeout(function()
    {
        writeNext(i + 1);

    }, 2000);
}

writeNext(1);

You have an incredible number of choices to achieve delegates in C++. Here are the ones that came to my mind.

Option 1 : functors:

A function object may be created by implementing operator()

struct Functor
{
     // Normal class/struct members

     int operator()(double d) // Arbitrary return types and parameter list
     {
          return (int) d + 1;
     }
};

// Use:
Functor f;
int i = f(3.14);

Option 2: lambda expressions (C++11 only)

// Syntax is roughly: [capture](parameter list) -> return type {block}
// Some shortcuts exist
auto func = [](int i) -> double { return 2*i/1.15; };
double d = func(1);

Option 3: function pointers

int f(double d) { ... }
typedef int (*MyFuncT) (double d);
MyFuncT fp = &f;
int a = fp(3.14);

Option 4: pointer to member functions (fastest solution)

See Fast C++ Delegate (on The Code Project).

struct DelegateList
{
     int f1(double d) { }
     int f2(double d) { }
};

typedef int (DelegateList::* DelegateType)(double d);

DelegateType d = &DelegateList::f1;
DelegateList list;
int a = (list.*d)(3.14);

Option 5: std::function

(or boost::function if your standard library doesn't support it). It is slower, but it is the most flexible.

#include <functional>
std::function<int(double)> f = [can be set to about anything in this answer]
// Usually more useful as a parameter to another functions

Option 6: binding (using std::bind)

Allows setting some parameters in advance, convenient to call a member function for instance.

struct MyClass
{
    int DoStuff(double d); // actually a DoStuff(MyClass* this, double d)
};

std::function<int(double d)> f = std::bind(&MyClass::DoStuff, this, std::placeholders::_1);
// auto f = std::bind(...); in C++11

Option 7: templates

Accept anything as long as it matches the argument list.

template <class FunctionT>
int DoSomething(FunctionT func)
{
    return func(3.14);
}

Solution in one single line:

const [,forceRender] = useReducer((s) => s+1, 0)

You can learn about useReducer here. https://reactjs.org/docs/hooks-reference.html#usereducer

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

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

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

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

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

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

const int is identical to int const, as is true with all scalar types in C. In general, declaring a scalar function parameter as const is not needed, since C's call-by-value semantics mean that any changes to the variable are local to its enclosing function.

You can use the Oracle Data Modeler to create auto incrementing surrogate keys.

Step 1. - Create a Relational Diagram

You can first create a Logical Diagram and Engineer to create the Relational Diagram or you can straightaway create the Relational Diagram.

Add the entity (table) that required to have auto incremented PK, select the type of the PK as Integer.

Step 2. - Edit PK Column Property

Get the properties of the PK column. You can double click the name of the column or click on the 'Properties' button.

Column Properties dialog box appears.

Select the General Tab (Default Selection for the first time). Then select both the 'Auto Increment' and 'Identity Column' check boxes.

Step 3. - Additional Information

Additional information relating to the auto increment can be specified by selecting the 'Auto Increment' tab.

• Start With
• Increment By
• Min Value
• Max Value
• Cycle
• Disable Cache
• Order
• Sequence Name
• Trigger Name
• Generate Trigger

It is usually a good idea to mention the sequence name, so that it will be useful in PL/SQL.

Click OK (Apply) to the Column Properties dialog box.

Click OK (Apply) to the Table Properties dialog box.

Table appears in the Relational Diagram.

Changing a CheckBox appearance to Button will give you difficulty in adjustments. You cannot change its dimensions because its size depends on the size of your text or image.

You can try this: (initialize the count variable first to 1 | int count = 1)

private void settingsBtn_Click(object sender, EventArgs e)
    {
        count++;

        if (count % 2 == 0)
        {
            settingsPanel.Show();
        }
        else
        {
            settingsPanel.Hide();
        }
    }

It's very simple but it works.

Warning: This will work well with buttons that are occasionally used (i.e. settings), the value of count in int/long may be overloaded when used more than it's capacity without closing the app's process. (Check data type ranges: http://msdn.microsoft.com/en-us/library/s3f49ktz.aspx)

The Good News: If you're running an app that is not intended for use 24/7 all-year round, I think this is helpful. Important thing is that when the app's process ended and you run it again, the count will reset to 1.

Use the following snippet to add a Switch to your layout via XML:

<Switch
     android:id="@+id/on_off_switch"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:textOff="OFF"
     android:textOn="ON"/>

Then in your Activity's onCreate method, get a reference to your Switch and set its OnCheckedChangeListener:

Switch onOffSwitch = (Switch)  findViewById(R.id.on_off_switch); 
onOffSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    Log.v("Switch State=", ""+isChecked);
}       

});

Here's a simple example to demonstrate Map usage:

Map<String, String> map = new HashMap<String, String>();
map.put("Color1","Red");
map.put("Color2","Blue");
map.put("Color3","Green");
map.put("Color4","White");

System.out.println(map);
// {Color4=White, Color3=Green, Color1=Red, Color2=Blue}        

System.out.println(map.get("Color2")); // Blue

System.out.println(map.keySet());
// [Color4, Color3, Color1, Color2]

for (Map.Entry<String,String> entry : map.entrySet()) {
    System.out.printf("%s -> %s%n", entry.getKey(), entry.getValue());
}
// Color4 -> White
// Color3 -> Green
// Color1 -> Red
// Color2 -> Blue

Note that the entries are iterated in arbitrary order. If you need a specific order, then you may consider e.g. LinkedHashMap

A different answer to my earlier one, based on exposure to the Google Java Collections:

public static class Lists
{
    public static List<T> Of<T>(T item)
    {
        return new List<T> { item };
    }
}

Then:

List<string> x = Lists.Of("Hello");

I advise checking out the GJC - it's got lots of interesting stuff in. (Personally I'd ignore the "alpha" tag - it's only the open source version which is "alpha" and it's based on a very stable and heavily used internal API.)

Make sure your variables are in scope for the method that is referencing it. For example I had defined a textview locally in a method in the class and was referencing it in another method.

I moved the textview definition outside the method right below the class definition so the other method could access the definition, which resolved the problem.

after passing the vector by reference

swap(vector[position],vector[otherPosition]);

will produce the expected result.

If you are using angular-cli, then you can check it easily by typing

ng -v

or ng v in Angular 8, in Terminal or Bash. Note: Run the command within the project directory.

You should get something like this:

angular-cli: 1.0.0-beta.24
node: 7.4.0
os: darwin x64
@angular/common: 2.4.3
@angular/compiler: 2.4.3
@angular/core: 2.4.3
@angular/forms: 2.4.3
@angular/http: 2.4.3
@angular/platform-browser: 2.4.3
@angular/platform-browser-dynamic: 2.4.3
@angular/router: 3.4.3
@angular/compiler-cli: 2.4.3

You can achieve this by setting content mode of image view to UIViewContentModeScaleAspectFill.

Then use following method method to get the resized uiimage object.

- (UIImage*)setProfileImage:(UIImage *)imageToResize onImageView:(UIImageView *)imageView
{
    CGFloat width = imageToResize.size.width;
    CGFloat height = imageToResize.size.height;
    float scaleFactor;
    if(width > height)
    {
        scaleFactor = imageView.frame.size.height / height;
    }
    else
    {
        scaleFactor = imageView.frame.size.width / width;
    }

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(width * scaleFactor, height * scaleFactor), NO, 0.0);
    [imageToResize drawInRect:CGRectMake(0, 0, width * scaleFactor, height * scaleFactor)];
    UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return resizedImage;
}

Edited Here (Swift Version)

func setProfileImage(imageToResize: UIImage, onImageView: UIImageView) -> UIImage
{
    let width = imageToResize.size.width
    let height = imageToResize.size.height

    var scaleFactor: CGFloat

    if(width > height)
    {
        scaleFactor = onImageView.frame.size.height / height;
    }
    else
    {
        scaleFactor = onImageView.frame.size.width / width;
    }

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(width * scaleFactor, height * scaleFactor), false, 0.0)
    imageToResize.drawInRect(CGRectMake(0, 0, width * scaleFactor, height * scaleFactor))
    let resizedImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return resizedImage;

Unlike interfaces, abstract classes can contain fields that are not static and final, and they can contain implemented methods. Such abstract classes are similar to interfaces, except that they provide a partial implementation, leaving it to subclasses to complete the implementation. If an abstract class contains only abstract method declarations, it should be declared as an interface instead.

Multiple interfaces can be implemented by classes anywhere in the class hierarchy, whether or not they are related to one another in any way. Think of Comparable or Cloneable, for example.

By comparison, abstract classes are most commonly subclassed to share pieces of implementation. A single abstract class is subclassed by similar classes that have a lot in common (the implemented parts of the abstract class), but also have some differences (the abstract methods).

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

public class StringEqualityTest extends TestCase {
    public void testEquality() throws Exception {
        String a = "abcde";
        String b = new String(a);
        assertTrue(a.equals(b));
        assertFalse(a == b);
        assertEquals(a, b);
    }
}

Simple approach..See it via recursion..

<?php

function flatten_array($simple){
static $outputs=array();
foreach ( $simple as $value)
{
if(is_array($value)){
    flatten_array($value);
}
else{
    $outputs[]=$value;
}

}
return $outputs;
}

$eg=['s'=>['p','n'=>['t']]];
$out=flatten_array($eg);
print_r($out);

?>

You could check whether the value of your selectOneMenu component belongs to the list of subjects.

Namely:

public void subjectSelectionChanged() {
    // Cancel if subject is manually written
    if (!subjectList.contains(aktNachricht.subject)) { return; }
    // Write your code here in case the user selected (or wrote) an item of the list
    // ....
}

Supposedly subjectList is a collection type, like ArrayList. Of course here your code will run in case the user writes an item of your selectOneMenu list.

If you need to order the files by specific parameter (e.g. date time):

gci *.log | sort LastWriteTime | % {$(Get-Content $_)} | Set-Content result.log

I am working in python 3.4.3. I am cutting out a little typing that shows how I got here:

testing
>>>
[18:19 jsilverman@JSILVERMAN-LT7 pexpect]$ 

Did it work? Try redirecting stderr to a file and see what happens:

[18:22 jsilverman@JSILVERMAN-LT7 pexpect]$ python3 2> /tmp/test.txt
>>> import sys

Well, aside from the fact that the little introduction that python gives you has been slurped into stderr (where else would it go?), it works.

I recently had this problem myself, and once I determined which AppPool was causing the problem, the only way to resolve the issue was remove that app pool completly and create a new one for the site to use.

Here is my example with bash script inside .gitconfig alias section

[alias]
        pushall = "!f(){ for i in `git remote`; do git push $i; done; };f"

You should have the file at the same location as that of the Python files you are trying to import. Also 'from file import function' is enough.

They are user-defined signals, so they aren't triggered by any particular action. You can explicitly send them programmatically:

#include <signal.h>

kill(pid, SIGUSR1);

where pid is the process id of the receiving process. At the receiving end, you can register a signal handler for them:

#include <signal.h>

void my_handler(int signum)
{
    if (signum == SIGUSR1)
    {
        printf("Received SIGUSR1!\n");
    }
}

signal(SIGUSR1, my_handler);

Try using a <span> element instead. Or if you prefer, try display:inline

I faced similar problem of namespace/method not being found during execution although it was fine during compilation, and the reason for this appears to be that the assembly I was referencing was deployed to GAC and since then was changed, so when I referenced the assembly in Visual Studion it was using the most recent one, but during runtime the version fro GAC had been used.

Generally speaking:

F5 may give you the same page even if the content is changed, because it may load the page from cache. But Ctrl-F5 forces a cache refresh, and will guarantee that if the content is changed, you will get the new content.

You can look up the constraint name in the sys.key_constraints table:

SELECT name
FROM   sys.key_constraints
WHERE  [type] = 'PK'
       AND [parent_object_id] = Object_id('dbo.Student');

If you don't care about the name, but simply want to drop it, you can use a combination of this and dynamic sql:

DECLARE @table NVARCHAR(512), @sql NVARCHAR(MAX);

SELECT @table = N'dbo.Student';

SELECT @sql = 'ALTER TABLE ' + @table 
    + ' DROP CONSTRAINT ' + name + ';'
    FROM sys.key_constraints
    WHERE [type] = 'PK'
    AND [parent_object_id] = OBJECT_ID(@table);

EXEC sp_executeSQL @sql;

This code is from Aaron Bertrand (source).

Code for Python 3.6.1

print("This first text and " , end="")

print("second text will be on the same line")

print("Unlike this text which will be on a newline")

Output

>>>
This first text and second text will be on the same line
Unlike this text which will be on a newline

This error happen usually when tables in the query doesn't exist. Just check the table's spelling in the query, and it will work.

you can use..

   </div>
   <div style="float:right;">
   </div>
</div>

The differences between Model() and Model.objects.create() are the following:

1. INSERT vs UPDATE

   Model.save() does either INSERT or UPDATE of an object in a DB, while Model.objects.create() does only INSERT.

   Model.save() does

   • UPDATE If the object’s primary key attribute is set to a value that evaluates to True

   • INSERT If the object’s primary key attribute is not set or if the UPDATE didn’t update anything (e.g. if primary key is set to a value that doesn’t exist in the database).

2. Existing primary key

   If primary key attribute is set to a value and such primary key already exists, then Model.save() performs UPDATE, but Model.objects.create() raises IntegrityError.

   Consider the following models.py:

   class Subject(models.Model):
      subject_id = models.PositiveIntegerField(primary_key=True, db_column='subject_id')
      name = models.CharField(max_length=255)
      max_marks = models.PositiveIntegerField()
   

   1. Insert/Update to db with Model.save()

      physics = Subject(subject_id=1, name='Physics', max_marks=100)
      physics.save()
      math = Subject(subject_id=1, name='Math', max_marks=50)  # Case of update
      math.save()
      

      Result:

      Subject.objects.all().values()
      <QuerySet [{'subject_id': 1, 'name': 'Math', 'max_marks': 50}]>
      

   2. Insert to db with Model.objects.create()

      Subject.objects.create(subject_id=1, name='Chemistry', max_marks=100)
      IntegrityError: UNIQUE constraint failed: m****t.subject_id
      

   Explanation: In the example, math.save() does an UPDATE (changes name from Physics to Math, and max_marks from 100 to 50), because subject_id is a primary key and subject_id=1 already exists in the DB. But Subject.objects.create() raises IntegrityError, because, again the primary key subject_id with the value 1 already exists.

3. Forced insert

   Model.save() can be made to behave as Model.objects.create() by using force_insert=True parameter: Model.save(force_insert=True).

4. Return value

   Model.save() return None where Model.objects.create() return model instance i.e. package_name.models.Model

Conclusion: Model.objects.create() does model initialization and performs save() with force_insert=True.

Excerpt from the source code of Model.objects.create()

def create(self, **kwargs):
    """
    Create a new object with the given kwargs, saving it to the database
    and returning the created object.
    """
    obj = self.model(**kwargs)
    self._for_write = True
    obj.save(force_insert=True, using=self.db)
    return obj

Your post contains several questions, so I'll try to answer them one at a time:

1. The API you're interested in is the Product Advertising API (PA). It allows you programmatic access to search and retrieve product information from Amazon's catalog. If you're having trouble finding information on the API, that's because the web service has undergone two name changes in recent history: it was also known as ECS and AAWS.
2. The signature process you're referring to is the same HMAC signature that all of the other AWS services use for authentication. All that's required to sign your requests to the Product Advertising API is a function to compute a SHA-1 hash and and AWS developer key. For more information, see the section of the developer documentation on signing requests.
3. As far as I know, there is no support for retrieving RSS feeds of products or tags through PA. If anyone has information suggesting otherwise, please correct me.
4. Either the REST or SOAP APIs should make your use case very straight forward. Amazon provides a fairly basic "getting started" guide available here. As well, you can view the complete API developer documentation here.

Although the documentation is a little hard to find (likely due to all the name changes), the PA API is very well documented and rather elegant. With a modicum of elbow grease and some previous experience in calling out to web services, you shouldn't have any trouble getting the information you need from the API.

<div id="ABLAHALAHOO">8008</div>
<div id="WABOOLAWADO">1110</div>

parseInt( $( '#ABLAHALAHOO' ).text()) > parseInt( $( '#WABOOLAWADO ).text()) ? alert( 'Eat potato' ) : alert( 'You starve' );

file = open('Failed.py', 'w')
file.write('whatever')
file.close()

Here is a more pythonic version, which automatically closes the file, even if there was an exception in the wrapped block:

with open('Failed.py', 'w') as file:
    file.write('whatever')

Official Definition

From the reference docs of Comparable.compareTo(T):

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure sgn(x.compareTo(y)) == -sgn(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception iff y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y)>0 && y.compareTo(z)>0) implies x.compareTo(z)>0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that sgn(x.compareTo(z)) == sgn(y.compareTo(z)), for all z.

It is strongly recommended, but not strictly required that (x.compareTo(y)==0) == (x.equals(y)). Generally speaking, any class that implements the Comparable interface and violates this condition should clearly indicate this fact. The recommended language is "Note: this class has a natural ordering that is inconsistent with equals."

In the foregoing description, the notation sgn(expression) designates the mathematical signum function, which is defined to return one of -1, 0, or 1 according to whether the value of expression is negative, zero or positive.

My Version

In short:

this.compareTo(that)

returns

• a negative int if this < that
• 0 if this == that
• a positive int if this > that

where the implementation of this method determines the actual semantics of < > and == (I don't mean == in the sense of java's object identity operator)

Examples

"abc".compareTo("def")

will yield something smaller than 0 as abc is alphabetically before def.

Integer.valueOf(2).compareTo(Integer.valueOf(1))

will yield something larger than 0 because 2 is larger than 1.

Some additional points

Note: It is good practice for a class that implements Comparable to declare the semantics of it's compareTo() method in the javadocs.

Note: you should read at least one of the following:

• the Object Ordering section of the Collection Trail in the Sun Java Tutorial
• Effective Java by Joshua Bloch, especially item 12: Consider implementing Comparable
• Java Generics and Collections by Maurice Naftalin, Philip Wadler, chapter 3.1: Comparable

Warning: you should never rely on the return values of compareTo being -1, 0 and 1. You should always test for x < 0, x == 0, x > 0, respectively.

Locate the installation path of GlassFish. Then move to domains/domain-dir/logs/ and you'll find there the log files. If you have created the domain with NetBeans, the domain-dir is most probably called domain1.

See this link for the official GlassFish documentation about logging.

Just use the already built-in Contains() method:

using System.Linq;

//...

string[] array = { "foo", "bar" };
if (array.Contains("foo")) {
    //...
}

Have you noticed that you don't get the error if you run

python ./script.py

instead of

python script.py

This is because sys.argv[0] will read ./script.py in the former case, which gives os.path.dirname something to work with. When you don't specify a path, sys.argv[0] reads simply script.py, and os.path.dirname cannot determine a path.

To me, the correct way of doing it would be the ones listed. Either ajax or ajaxSetup. If you really want to use get and not use ajaxSetup then you could create your own parameter and give it the value of the the current date/time.

I would however question your motives in not using one of the other methods.

In more complicated build scenarios, it is common to break compilation into stages, with compilation and assembly happening first (output to object files), and linking object files into a final executable or library afterward--this prevents having to recompile all object files when their source files haven't changed. That's why including the linking flag -lm isn't working when you put it in CFLAGS (CFLAGS is used in the compilation stage).

The convention for libraries to be linked is to place them in either LOADLIBES or LDLIBS (GNU make includes both, but your mileage may vary):

LDLIBS=-lm

This should allow you to continue using the built-in rules rather than having to write your own linking rule. For other makes, there should be a flag to output built-in rules (for GNU make, this is -p). If your version of make does not have a built-in rule for linking (or if it does not have a placeholder for -l directives), you'll need to write your own:

client.o: client.c
    $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c -o $@ $<

client: client.o
    $(CC) $(LDFLAGS) $(TARGET_ARCH) $^ $(LOADLIBES) $(LDLIBS) -o $@

Define a class like this :

public class myclass {
       string id ;
       string title ;
       string content;
 }

 public class program {
        public void Main () {
               List<myclass> objlist = new List<myclass> () ;
               foreach (var value in objlist)  {
                       TextBox1.Text = value.id ;
                       TextBox2.Text= value.title;
                       TextBox3.Text= value.content ;
                }
         }
  }

I tried to draw a sketch and you can improve it in many ways. Instead of defining class "myclass", you can define struct.

Use the HorizontalAlignment and VerticalAlignment layout properties. They control how an element uses the space it has inside its parent when more room is available than it required by the element.

The width of a StackPanel, for example, will be as wide as the widest element it contains. So, all narrower elements have a bit of excess space. The alignment properties control what the child element does with the extra space.

The default value for both properties is Stretch, so the child element is stretched to fill all available space. Additional options include Left, Center and Right for HorizontalAlignment and Top, Center and Bottom for VerticalAlignment.

curl sends POST requests with the default content type of application/x-www-form-urlencoded. If you want to send a JSON request, you will have to specify the correct content type header:

$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"

But that will only work if the server accepts json input. The .json at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.

The reason you get a 401 and not some other error is probably because the server can't extract the auth_token from your request.

var url = "https://yourURL.com";

//String.Format("{0:HH:mm}", dt);  // where dt is a DateTime variable

public static string FormatearHoraA24(DateTime? fechaHora)

    return retornar = String.Format("{0:HH:mm}", (DateTime)fechaHora);
}

All the 'use UDP' answers assume an open network and 'stuff it as much as you can' approach. Good for old-style closed-garden dedicated audio/video networks, which are a vanishing sort.

In the actual world, your transmission will go through firewalls (that will drop multicast and sometimes udp), the network is shared with others more important ($$$) apps, so you want to punish abusers with window scaling.

There are already a lot of answers here but I think there's another, perhaps better, way of doing this using the correct Calendar APIs.

I'd suggest getting the day of the week using the weekdaySymbols property of Calendar (docs) in an extension to Date:

extension Date {

    /// Returns the day of the week as a `String`, e.g. "Monday"
    var dayOfWeek: String {
        let calendar = Calendar.autoupdatingCurrent
        return calendar.weekdaySymbols[calendar.component(.weekday, from: self) - 1]
    }
}

This requires initialising a Date first, which I would do using a custom DateFormatter:

extension DateFormatter {

    /// returns a `DateFormatter` with the format "yyyy-MM-dd".
    static var standardDate: DateFormatter {
        let formatter = DateFormatter()
        formatter.dateFormat = "yyyy-MM-dd"
        return formatter
    }
}

This can then be called with:

DateFormatter.standardDate.date(from: "2018-09-18")!.dayOfWeek

Why I prefer this:

1. dayOfWeek does not have to care about time zones because the user's calendar is used, some of the other solutions here will show the incorrect day because time zones are not considered.
2. It's very likely that you'll need to use dates in the same format in other places so why not create a reusable DateFormatter and use that instead?
3. weekdaySymbols is localised for you.
4. weekDaySymbols can be replaced with other options such as shortWeekdaySymbols for "Mon", "Tues" etc.

Please note: This example DateFormatter also doesn't consider time zones or locales, you'll need to set them for what you need. If the dates are always precise, consider setting the time zone TimeZone(secondsFromGMT: 0).

You can use Jquery's on method and listen for the scroll event.

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

When you bind the .submit() event to the form, and you do the things you want to do before returning (true), these things happen prior to the actual submission.

For example:

    return true;
});

The docstring of fillna says that value should be a scalar or a dict, however, it seems to work with a Series as well. If you want to pass a dict, you could use df.mean().to_dict().

A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.

Eg

Private Sub worksheet_change(ByVal target As Range)
  target.Font.Bold = True
End Sub

Here is a refactored and simplified version of the @sasha_gud answer:

    [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
    [return: MarshalAs(UnmanagedType.Bool)]
    public static extern bool GetDiskFreeSpaceEx(string lpDirectoryName,
        out ulong lpFreeBytesAvailable,
        out ulong lpTotalNumberOfBytes,
        out ulong lpTotalNumberOfFreeBytes);

    public static ulong GetDiskFreeSpace(string path)
    {
        if (string.IsNullOrEmpty(path))
        {
            throw new ArgumentNullException("path");
        }

        ulong dummy = 0;

        if (!GetDiskFreeSpaceEx(path, out ulong freeSpace, out dummy, out dummy))
        {
            throw new Win32Exception(Marshal.GetLastWin32Error());
        }

        return freeSpace;
    }

If the function floatval does not work you can try to make this :

    $string = "2968789218";
    $float = $string * 1.0;
    echo $float;

But for me all the previous answer worked ( try it in http://writecodeonline.com/php/ ) Maybe the problem is on your server ?

I had to set searchPseudoElements to to true to get it working in Angular5.

import fontawesome from '@fortawesome/fontawesome';
...
fontawesome.config.searchPseudoElements = true;
...
content: "\f12a";
font-family: 'Font Awesome 5 Solid';

The Substring method provides us a way to extract a particular string from the original string based on a starting position and length. If only one argument is provided, it is taken to be the starting position, and the remainder of the string is outputted.

PS > "test_string".Substring(0,4)
Test
PS > "test_string".Substring(4)
_stringPS >

link text

But this is easier...

 $s = 'Hello World is in here Hello World!'
 $p = 'Hello World'
 $s -match $p

And finally, to recurse through a directory selecting only the .txt files and searching for occurrence of "Hello World":

dir -rec -filter *.txt | Select-String 'Hello World'

If you couldn't have the items OBJ equal to null, you can do this:

$scope.isEmpty = function (obj) {
    for (var i in obj) if (obj.hasOwnProperty(i)) return false;
    return true;
};

and in the view you can do:

<div ng-show="isEmpty(items)"></div>

You can do

var ob = {};
Object.keys(ob).length

Only if your browser supports ECMAScript 5. For Example, IE 8 doesn't support this feature.

Client side Upload Canceling

On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE, can be tampered with so always use server side validation.

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input type="file" name="file" id="file" />
    <input type="submit" name="submit" value="Submit" />
</form>

<script>
document.forms[0].addEventListener('submit', function( evt ) {
    var file = document.getElementById('file').files[0];

    if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
        //Submit form        
    } else {
        //Prevent default and display error
        evt.preventDefault();
    }
}, false);
</script>

Server Side Upload Canceling

On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.

PHP Validation

On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES array to find out the upload size. (Docs on the contents of $_FILES can be found below the MAX_FILE_SIZE docs)

upload.php

<?php
if(isset($_FILES['file'])) {
    if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
        // File too big
    } else {
        // File within size restrictions
    }
}

create a filter.js and you can make this as reusable

angular.module('yourmodule').filter('date', function($filter)
{
    return function(input)
    {
        if(input == null){ return ""; }
        var _date = $filter('date')(new Date(input), 'dd/MM/yyyy');
        return _date.toUpperCase();
    };
});

view

<span>{{ d.time | date }}</span>

or in controller

var filterdatetime = $filter('date')( yourdate );

What it does

Maven is a "build management tool", it is for defining how your .java files get compiled to .class, packaged into .jar (or .war or .ear) files, (pre/post)processed with tools, managing your CLASSPATH, and all others sorts of tasks that are required to build your project. It is similar to Apache Ant or Gradle or Makefiles in C/C++, but it attempts to be completely self-contained in it that you shouldn't need any additional tools or scripts by incorporating other common tasks like downloading & installing necessary libraries etc.

It is also designed around the "build portability" theme, so that you don't get issues as having the same code with the same buildscript working on one computer but not on another one (this is a known issue, we have VMs of Windows 98 machines since we couldn't get some of our Delphi applications compiling anywhere else). Because of this, it is also the best way to work on a project between people who use different IDEs since IDE-generated Ant scripts are hard to import into other IDEs, but all IDEs nowadays understand and support Maven (IntelliJ, Eclipse, and NetBeans). Even if you don't end up liking Maven, it ends up being the point of reference for all other modern builds tools.

Why you should use it

There are three things about Maven that are very nice.

1. Maven will (after you declare which ones you are using) download all the libraries that you use and the libraries that they use for you automatically. This is very nice, and makes dealing with lots of libraries ridiculously easy. This lets you avoid "dependency hell". It is similar to Apache Ant's Ivy.

2. It uses "Convention over Configuration" so that by default you don't need to define the tasks you want to do. You don't need to write a "compile", "test", "package", or "clean" step like you would have to do in Ant or a Makefile. Just put the files in the places in which Maven expects them and it should work off of the bat.

3. Maven also has lots of nice plug-ins that you can install that will handle many routine tasks from generating Java classes from an XSD schema using JAXB to measuring test coverage with Cobertura. Just add them to your pom.xml and they will integrate with everything else you want to do.

The initial learning curve is steep, but (nearly) every professional Java developer uses Maven or wishes they did. You should use Maven on every project although don't be surprised if it takes you a while to get used to it and that sometimes you wish you could just do things manually, since learning something new sometimes hurts. However, once you truly get used to Maven you will find that build management takes almost no time at all.

How to Start

The best place to start is "Maven in 5 Minutes". It will get you start with a project ready for you to code in with all the necessary files and folders set-up (yes, I recommend using the quickstart archetype, at least at first).

After you get started you'll want a better understanding over how the tool is intended to be used. For that "Better Builds with Maven" is the most thorough place to understand the guts of how it works, however, "Maven: The Complete Reference" is more up-to-date. Read the first one for understanding, but then use the second one for reference.

All has been pointed out. Just use either DELETE ON CASCADE on the parent table or delete from the child-table and then parent.

reference :

Makefile.am -- a user input file to automake

configure.in -- a user input file to autoconf

autoconf generates configure from configure.in

automake gererates Makefile.in from Makefile.am

configure generates Makefile from Makefile.in

For ex:

$]
configure.in Makefile.in
$] sudo autoconf
configure configure.in Makefile.in ... 
$] sudo ./configure
Makefile Makefile.in

sending mail in php is not a one-step process. mail() returns true/false, but even if it returns true, it doesn't mean the message is going to be sent. all mail() does is add the message to the queue(using sendmail or whatever you set in php.ini)

there is no reliable way to check if the message has been sent in php. you will have to look through the mail server logs.

In my case I had to implement MainActivity as Serializable too. Cause I needed to start a service from my MainActivity :

public class MainActivity extends AppCompatActivity implements Serializable {
    ...
    musicCover = new MusicCover(); // A Serializable Object
    ...
    sIntent = new Intent(MainActivity.this, MusicPlayerService.class);
    sIntent.setAction(MusicPlayerService.ACTION_INITIALIZE_COVER);
    sIntent.putExtra(MusicPlayerService.EXTRA_COVER, musicCover);
    startService(sIntent);
}

Unless you do some kind of post-processing work, the video will never be better than the original frames. Also just like a flip-book, if you have a big "jump" between keyframes it will look funny. You generally need enough "tweens" in between the keyframes to give smooth animation. HTH

This Javascript function purports to show the difference between the Blob File API and the Data API to download a JSON file in the client browser:

/**_x000D_
 * Save a text as file using HTML <a> temporary element and Blob_x000D_
 * @author Loreto Parisi_x000D_
 */_x000D_
_x000D_
var saveAsFile = function(fileName, fileContents) {_x000D_
    if (typeof(Blob) != 'undefined') { // Alternative 1: using Blob_x000D_
        var textFileAsBlob = new Blob([fileContents], {type: 'text/plain'});_x000D_
        var downloadLink = document.createElement("a");_x000D_
        downloadLink.download = fileName;_x000D_
        if (window.webkitURL != null) {_x000D_
            downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);_x000D_
        } else {_x000D_
            downloadLink.href = window.URL.createObjectURL(textFileAsBlob);_x000D_
            downloadLink.onclick = document.body.removeChild(event.target);_x000D_
            downloadLink.style.display = "none";_x000D_
            document.body.appendChild(downloadLink);_x000D_
        }_x000D_
        downloadLink.click();_x000D_
    } else { // Alternative 2: using Data_x000D_
        var pp = document.createElement('a');_x000D_
        pp.setAttribute('href', 'data:text/plain;charset=utf-8,' +_x000D_
            encodeURIComponent(fileContents));_x000D_
        pp.setAttribute('download', fileName);_x000D_
        pp.onclick = document.body.removeChild(event.target);_x000D_
        pp.click();_x000D_
    }_x000D_
} // saveAsFile_x000D_
_x000D_
/* Example */_x000D_
var jsonObject = {"name": "John", "age": 30, "car": null};_x000D_
saveAsFile('out.json', JSON.stringify(jsonObject, null, 2));

The function is called like saveAsFile('out.json', jsonString);. It will create a ByteStream immediately recognized by the browser that will download the generated file directly using the File API URL.createObjectURL.

In the else, it is possible to see the same result obtained via the href element plus the Data API, but this has several limitations that the Blob API has not.

Here is a revision of @Tayrn answer above that might help you understand pivoting a little easier:

This may not be the best way to do this, but this is what helped me wrap my head around how to pivot tables.

ID = rows you want to pivot

MY_KEY = the column you are selecting from your original table that contains the column names you want to pivot.

VAL = the value you want returning under each column.

MAX(VAL) => Can be replaced with other aggregiate functions. SUM(VAL), MIN(VAL), ETC...

DECLARE @cols AS NVARCHAR(MAX),
@query  AS NVARCHAR(MAX)
select @cols = STUFF((SELECT ',' + QUOTENAME(MY_KEY) 
                from yt
                group by MY_KEY
                order by MY_KEY ASC
        FOR XML PATH(''), TYPE
        ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,'')
set @query = 'SELECT ID,' + @cols + ' from 
         (
            select ID, MY_KEY, VAL 
            from yt
        ) x
        pivot 
        (
            sum(VAL)
            for MY_KEY in (' + @cols + ')
        ) p '

        execute(@query);

Compose an email in the phone email client:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "[email protected]" });
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));

Your code is way more cluttered than necessary.

Replace (Not (X Is Nothing)) with X IsNot Nothing and omit the outer parentheses:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For i As Integer = 0 To comp.Container.Components.Count() - 1
        fixUIIn(comp.Container.Components(i), style)
    Next
End If

Much more readable. … Also notice that I’ve removed the redundant Step 1 and the probably redundant .Item.

But (as pointed out in the comments), index-based loops are out of vogue anyway. Don’t use them unless you absolutely have to. Use For Each instead:

If comp.Container IsNot Nothing AndAlso comp.Container.Components IsNot Nothing Then
    For Each component In comp.Container.Components
        fixUIIn(component, style)
    Next
End If

If you happen to process the value with some string function before saving, make sure the function can properly handle multibyte characters. String functions that cannot do that and are, say, attempting to truncate might split one of the single multibyte characters in the middle, and that can cause such string error situations.

In PHP for instance, you would need to switch from substr to mb_substr.

Update: It looks like the manual has been updated and the example I was referring to has been removed. See the edit to @flainez's answer above.

Original: Using @objc is the right way to do it even if you're not interoperating with Obj-C. It ensures that your protocol is being applied to a class and not an enum or struct. See "Checking for Protocol Conformance" in the manual.

encodeURIComponent(JSON.stringify(object_to_be_serialised))

You could just create an array of the correct size up-front and fill it:

frames = np.empty((480, 640, 3, 100))

for k in xrange(nframes):
    frames[:,:,:,k] = cv2.imread('frame_{}.jpg'.format(k))

if the frames were individual jpg file that were named in some particular way (in the example, frame_0.jpg, frame_1.jpg, etc).

Just a note, you might consider using a (nframes, 480,640,3) shaped array, instead.

Using the rowid() function in data.table:

> set.seed(100)  
> df <- data.frame(cat = c(rep("aaa", 5), rep("bbb", 5), rep("ccc", 5)), val = runif(15))
> df <- df[order(df$cat, df$val), ]  
> df$num <- data.table::rowid(df$cat)
> df
   cat        val num
4  aaa 0.05638315   1

1. Put source files into a zip file (as it does for java source)
2. Go to Project properties -> Libraries
3. Select Source attachment and click 'Edit'
4. On Source Attachment Configuration click 'Variable'
5. On "Variable Selection" click 'New'
6. Put a meaningful name and select the zip file created in step 1

You can just create a shortcut and then right click on it -> properties -> change icon, and just browse for your desired icon. Hope this help.

To set an icon of a shortcut programmatically, see this article using SetIconLocation:

How Can I Change the Icon for an Existing Shortcut?:

https://devblogs.microsoft.com/scripting/how-can-i-change-the-icon-for-an-existing-shortcut/

Const DESKTOP = &H10&
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.NameSpace(DESKTOP)
Set objFolderItem = objFolder.ParseName("Test Shortcut.lnk")
Set objShortcut = objFolderItem.GetLink
objShortcut.SetIconLocation "C:\Windows\System32\SHELL32.dll", 13
objShortcut.Save

I use Butterknife with switch-case to handle this kind of cases:

    @OnClick({R.id.button_bireysel, R.id.button_kurumsal})
        public void onViewClicked(View view) {
            switch (view.getId()) {


                case R.id.button_bireysel:
 //Do something

                    break;
                case R.id.button_kurumsal:

     //Do something

                    break;

            }
        }

But the thing is there is no default case and switch statement falls through

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 28800
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 28800

At first, wait_timeout = 28800 which is the default value. To change the session value, you need to set the global variable because the session variable is read-only.

SET @@GLOBAL.wait_timeout=300

After you set the global variable, the session variable automatically grabs the value.

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 300
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 300

Next time when the server restarts, the session variables will be set to the default value i.e. 28800.

P.S. I m using MySQL 5.6.16

Search for "php version" at the bottom of the cpanel

Select PHP Version -> Switch to Php Options -> Change the Value -> save.

Here is the most concise solution so far:

function isArrayOfStrings(value: any): boolean {
   return Array.isArray(value) && value.every(item => typeof item === "string");
}

Note that value.every will return true for an empty array. If you need to return false for an empty array, you should add value.length to the condition clause:

function isNonEmptyArrayOfStrings(value: any): boolean {
    return Array.isArray(value) && value.length && value.every(item => typeof item === "string");
}

There is no any run-time type information in TypeScript (and there won't be, see TypeScript Design Goals > Non goals, 5), so there is no way to get the type of an empty array. For a non-empty array all you can do is to check the type of its items, one by one.

Replace '+' with '000'. For example, 'U+1F600' will become 'U0001F600' and prepend the Unicode code with "\" and print. Example:

>>> print("Learning : ", "\U0001F40D")
Learning :  
>>> 

Check this maybe it will help python unicode emoji

try this. (I modified the example on the purpose of making it non trivial)

import operator
import numpy as np

n=10
a = list(range(n))
a1 = [1]*len(a)
an = np.array(a)

operator.add is almost more than two times faster

%timeit map(operator.add, a, a1)

than adding with numpy

%timeit an+1

I was surprised to read section 3.3.2 about rejecting cookies:

http://tools.ietf.org/html/rfc2965

That says that a browser should reject a cookie from x.y.z.com with domain .z.com, because 'x.y' contains a dot. So, unless I am misinterpreting the RFC and/or the questions above, there could be questions added:

Will a cookie for .example.com be available for www.yyy.example.com? No.

Will a cookie set by origin server www.yyy.example.com, with domain .example.com, have it's value sent by the user agent to xxx.example.com? No.

If you are asking if you can pair two devices without the user EVER approving the pairing, no it cannot be done, it is a security feature. If you are paired over Bluetooth there is no need to exchange data over NFC, just exchange data over the Bluetooth link.

I don't think you can circumvent Bluetooth security by passing an authentication packet over NFC, but I could be wrong.

I use this solution:

It's a bit more concise since I use: ng-repeat="obj in objects | filter : paginate" to filter the rows. Also made it working with $resource:

http://plnkr.co/edit/79yrgwiwvan3bAG5SnKx?p=preview

set the target attribute of your <a> element to "_tab"

EDIT: It works, however W3Schools says there is no such target attribute: http://www.w3schools.com/tags/att_a_target.asp

EDIT2: From what I've figured out from the comments. setting target to _blank will take you to a new tab or window (depending on your browser settings). Typing anything except one of the ones below will create a new tab group (I'm not sure how these work):

_blank  Opens the linked document in a new window or tab
_self   Opens the linked document in the same frame as it was clicked (this is default)
_parent Opens the linked document in the parent frame
_top    Opens the linked document in the full body of the window
framename   Opens the linked document in a named frame

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

I got this error on my ASP.Net 4.5 app on Windows Server 2012 R2.

Go to start menu -> "Turn windows features on or off". A wizard popped up for me.

Click Next to Server Roles

I had to check these to get this to work, located under Web Server IIS->Web Server-> Application Development (these are based on Jeremy Cook's answer above):

Then click next to Features and make sure the following is checked:

Then click next and Install. At this point, the error went away for me. Good luck!

$("#filter").click(function(){
    //Put your code here
});

Same problem for me on apache http client 4.5.5 adding default header

Connection: close

resolve the problem

Use include("class.classname.php");

And class should use <?php //code ?> not <? //code ?>

Try this code:

imgView.setImageResource(android.R.color.transparent); 

also this one works:

imgView.setImageResource(0); 

but be careful this one doesn't work:

imgView.setImageResource(null); 

Be careful, in some cases clicking on a Form Control or Active X Control will give two different results for the same macro - which should not be the case. I find Active X more reliable.

I suggest you to use LinkedHashSet most of the time, because it has better performance overall):

1. Predictable iteration order LinkedHashSet (Oracle)
2. LinkedHashSet is more expensive for insertions than HashSet;
3. In general slightly better performance than HashMap, because the most of the time we use Set structures for iterating.

It's used for raising errors.

if something:
    raise Exception('My error!')

Some examples here

Here's what I used to get information on an undocumented (3rd-party) intent:

Bundle bundle = intent.getExtras();
if (bundle != null) {
    for (String key : bundle.keySet()) {
        Log.e(TAG, key + " : " + (bundle.get(key) != null ? bundle.get(key) : "NULL"));
    }
}

Make sure to check if bundle is null before the loop.

A simple way to see remote branches is:

git branch -r

To see local branches:

git branch -l

Closed formula for the longest int (I used int here, but works for any signed integral type):

1 + (int) ceil((8*sizeof(int)-1) * log10(2))

Explanation:

                  sizeof(int)                 // number bytes in int
                8*sizeof(int)                 // number of binary digits (bits)
                8*sizeof(int)-1               // discount one bit for the negatives
               (8*sizeof(int)-1) * log10(2)   // convert to decimal, because:
                                              // 1 bit == log10(2) decimal digits
    (int) ceil((8*sizeof(int)-1) * log10(2))  // round up to whole digits
1 + (int) ceil((8*sizeof(int)-1) * log10(2))  // make room for the minus sign

For an int type of 4 bytes, the result is 11. An example of 4 bytes int with 11 decimal digits is: "-2147483648".

If you want the number of decimal digits of some int value, you can use the following function:

unsigned base10_size(int value)
{
    if(value == 0) {
        return 1u;
    }

    unsigned ret;
    double dval;
    if(value > 0) {
        ret = 0;
        dval = value;
    } else {
        // Make room for the minus sign, and proceed as if positive.
        ret = 1;
        dval = -double(value);
    }

    ret += ceil(log10(dval+1.0));

    return ret;
}

I tested this function for the whole range of int in g++ 9.3.0 for x86-64.

Use the ref keyword.

Look at the definitive reference here to understand passing parameters.
To be specific, look at this, to understand the behavior of the code.

EDIT: Sort works on the same reference (that is passed by value) and hence the values are ordered. However, assigning a new instance to the parameter won't work because parameter is passed by value, unless you put ref.

Putting ref lets you change the pointer to the reference to a new instance of List in your case. Without ref, you can work on the existing parameter, but can't make it point to something else.

There are already answers which give how to change Inner HTML of element.

But I would suggest, you should use some animation like Fade Out/ Fade In to change HTML which gives good effect of changed HTML rather instantly changing inner HTML.

Use animation to change Inner HTML

$('#regTitle').fadeOut(500, function() {
    $(this).html('Hello World!').fadeIn(500);
});

If you have many functions which need this, then you can call common function which changes inner Html.

function changeInnerHtml(elementPath, newText){
    $(elementPath).fadeOut(500, function() {
        $(this).html(newText).fadeIn(500);
    });
}

It may also be usefull to understand the difference in term of Session Bean Identity when using @EJB and @Inject. According to the specifications the following code will always be true:

@EJB Cart cart1;
@EJB Cart cart2;
… if (cart1.equals(cart2)) { // this test must return true ...}

Using @Inject instead of @EJB there is not the same.

see also stateless session beans identity for further info

The documentation for this is good if not a little difficult to find.

Facebook Graph API - Page Tokens

After initializing node's fbgraph, you can run:

var facebookAccountID = yourAccountIdHere 

graph
.setOptions(options)
.get(facebookAccountId + "/accounts", function(err, res) {
  console.log(res); 
});

and receive a JSON response with the token you want to grab, located at:

res.data[0].access_token

Terminal opens a login shell. This means, ~/.bash_profile will get executed, ~/.bashrc not.

The solution on most systems is to "require" the ~/.bashrc in the ~/.bash_profile: just put this snippet in your ~/.bash_profile:

[[ -s ~/.bashrc ]] && source ~/.bashrc

In a code compiled with Java 7 but potentially running in a higher java version, it seems useful to detect presence of java.util.Base64 class and use the approach best for given JVM mentioned in other questions here.

I used this code:

private static final Method JAVA_UTIL_BASE64_GETENCODER;

static {
    Method getEncoderMethod;
    try {
        final Class<?> base64Class = Class.forName("java.util.Base64");
        getEncoderMethod = base64Class.getMethod("getEncoder");
    } catch (ClassNotFoundException | NoSuchMethodException e) {
        getEncoderMethod = null;
    }
    JAVA_UTIL_BASE64_GETENCODER = getEncoderMethod;
}

static String base64EncodeToString(String s) {
    final byte[] bytes = s.getBytes(StandardCharsets.ISO_8859_1);
    if (JAVA_UTIL_BASE64_GETENCODER == null) {
        // Java 7 and older // TODO: remove this branch after switching to Java 8
        return DatatypeConverter.printBase64Binary(bytes);
    } else {
        // Java 8 and newer
        try {
            final Object encoder = JAVA_UTIL_BASE64_GETENCODER.invoke(null);
            final Class<?> encoderClass = encoder.getClass();
            final Method encodeMethod = encoderClass.getMethod("encode", byte[].class);
            final byte[] encodedBytes = (byte[]) encodeMethod.invoke(encoder, bytes);
            return new String(encodedBytes);
        } catch (NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
            throw new IllegalStateException(e);

Preface

This post is meant to be an easy-to-read alternative to litb's post.

The underlying purpose is the same; an explanation to "When?" and "Why?" typename and template must be applied.

What's the purpose of typename and template?

typename and template are usable in circumstances other than when declaring a template.

There are certain contexts in C++ where the compiler must explicitly be told how to treat a name, and all these contexts have one thing in common; they depend on at least one template-parameter.

We refer to such names, where there can be an ambiguity in interpretation, as; "dependent names".

This post will offer an explanation to the relationship between dependent-names, and the two keywords.

A snippet says more than 1000 words

Try to explain what is going on in the following function-template, either to yourself, a friend, or perhaps your cat; what is happening in the statement marked (A)?

template<class T> void f_tmpl () { T::foo * x; /* <-- (A) */ }

It might not be as easy as one thinks, more specifically the result of evaluating (A) heavily depends on the definition of the type passed as template-parameter T.

Different Ts can drastically change the semantics involved.

struct X { typedef int       foo;       }; /* (C) --> */ f_tmpl<X> ();
struct Y { static  int const foo = 123; }; /* (D) --> */ f_tmpl<Y> ();

The two different scenarios:

• If we instantiate the function-template with type X, as in (C), we will have a declaration of a pointer-to int named x, but;

• if we instantiate the template with type Y, as in (D), (A) would instead consist of an expression that calculates the product of 123 multiplied with some already declared variable x.

The Rationale

The C++ Standard cares about our safety and well-being, at least in this case.

To prevent an implementation from potentially suffering from nasty surprises, the Standard mandates that we sort out the ambiguity of a dependent-name by explicitly stating the intent anywhere we'd like to treat the name as either a type-name, or a template-id.

If nothing is stated, the dependent-name will be considered to be either a variable, or a function.

How to handle dependent names?

If this was a Hollywood film, dependent-names would be the disease that spreads through body contact, instantly affects its host to make it confused. Confusion that could, possibly, lead to an ill-formed perso-, erhm.. program.

A dependent-name is any name that directly, or indirectly, depends on a template-parameter.

template<class T> void g_tmpl () {
   SomeTrait<T>::type                   foo; // (E), ill-formed
   SomeTrait<T>::NestedTrait<int>::type bar; // (F), ill-formed
   foo.data<int> ();                         // (G), ill-formed    
}

We have four dependent names in the above snippet:

• E)
  • "type" depends on the instantiation of SomeTrait<T>, which include T, and;
• F)
  • "NestedTrait", which is a template-id, depends on SomeTrait<T>, and;
  • "type" at the end of (F) depends on NestedTrait, which depends on SomeTrait<T>, and;
• G)
  • "data", which looks like a member-function template, is indirectly a dependent-name since the type of foo depends on the instantiation of SomeTrait<T>.

Neither of statement (E), (F) or (G) is valid if the compiler would interpret the dependent-names as variables/functions (which as stated earlier is what happens if we don't explicitly say otherwise).

The solution

To make g_tmpl have a valid definition we must explicitly tell the compiler that we expect a type in (E), a template-id and a type in (F), and a template-id in (G).

template<class T> void g_tmpl () {
   typename SomeTrait<T>::type foo;                            // (G), legal
   typename SomeTrait<T>::template NestedTrait<int>::type bar; // (H), legal
   foo.template data<int> ();                                  // (I), legal
}

Every time a name denotes a type, all names involved must be either type-names or namespaces, with this in mind it's quite easy to see that we apply typename at the beginning of our fully qualified name.

template however, is different in this regard, since there's no way of coming to a conclusion such as; "oh, this is a template, then this other thing must also be a template". This means that we apply template directly in front of any name that we'd like to treat as such.

Can I just stick the keywords in front of any name?

"Can I just stick typename and template in front of any name? I don't want to worry about the context in which they appear..." - Some C++ Developer

The rules in the Standard states that you may apply the keywords as long as you are dealing with a qualified-name (K), but if the name isn't qualified the application is ill-formed (L).

namespace N {
  template<class T>
  struct X { };
}

         N::         X<int> a; // ...  legal
typename N::template X<int> b; // (K), legal
typename template    X<int> c; // (L), ill-formed

^{Note: Applying typename or template in a context where it is not required is not considered good practice; just because you can do something, doesn't mean that you should.}

Additionally there are contexts where typename and template are explicitly disallowed:

• When specifying the bases of which a class inherits

  Every name written in a derived class's base-specifier-list is already treated as a type-name, explicitly specifying typename is both ill-formed, and redundant.

                      // .------- the base-specifier-list
    template<class T> // v
    struct Derived      : typename SomeTrait<T>::type /* <- ill-formed */ {
      ...
    };
  

  
  

• When the template-id is the one being referred to in a derived class's using-directive

    struct Base {
      template<class T>
      struct type { };
    };
  
    struct Derived : Base {
      using Base::template type; // ill-formed
      using Base::type;          // legal
    };
  

Here is based on the answer from Mark Tolonen. The string included different languages of the word 'test' that's separated by '|', so you can see the difference.

u = u'ABCtestß???másbêta|test|??????|??|??|???|???????|???????|????????|ki?m tra|Ölçek|'
e8 = u.encode('utf-8')        # encode without BOM
e8s = u.encode('utf-8-sig')   # encode with BOM
e16 = u.encode('utf-16')      # encode with BOM
e16le = u.encode('utf-16le')  # encode without BOM
e16be = u.encode('utf-16be')  # encode without BOM
print('utf-8     %r' % e8)
print('utf-8-sig %r' % e8s)
print('utf-16    %r' % e16)
print('utf-16le  %r' % e16le)
print('utf-16be  %r' % e16be)
print()
print('utf-8  w/ BOM decoded with utf-8     %r' % e8s.decode('utf-8'))
print('utf-8  w/ BOM decoded with utf-8-sig %r' % e8s.decode('utf-8-sig'))
print('utf-16 w/ BOM decoded with utf-16    %r' % e16.decode('utf-16'))
print('utf-16 w/ BOM decoded with utf-16le  %r' % e16.decode('utf-16le'))

I've been going back and forth on these two options the last few times I've needed them. Up until recently, my preference has been for the sealed trait/case object option.

1) Scala Enumeration Declaration

object OutboundMarketMakerEntryPointType extends Enumeration {
  type OutboundMarketMakerEntryPointType = Value

  val Alpha, Beta = Value
}

2) Sealed Traits + Case Objects

sealed trait OutboundMarketMakerEntryPointType

case object AlphaEntryPoint extends OutboundMarketMakerEntryPointType

case object BetaEntryPoint extends OutboundMarketMakerEntryPointType

While neither of these really meet all of what a java enumeration gives you, below are the pros and cons:

Scala Enumeration

Pros: -Functions for instantiating with option or directly assuming accurate (easier when loading from a persistent store) -Iteration over all possible values is supported

Cons: -Compilation warning for non-exhaustive search is not supported (makes pattern matching less ideal)

Case Objects/Sealed traits

Pros: -Using sealed traits, we can pre-instantiate some values while others can be injected at creation time -full support for pattern matching (apply/unapply methods defined)

Cons: -Instantiating from a persistent store - you often have to use pattern matching here or define your own list of all possible 'enum values'

What ultimately made me change my opinion was something like the following snippet:

object DbInstrumentQueries {
  def instrumentExtractor(tableAlias: String = "s")(rs: ResultSet): Instrument = {
    val symbol = rs.getString(tableAlias + ".name")
    val quoteCurrency = rs.getString(tableAlias + ".quote_currency")
    val fixRepresentation = rs.getString(tableAlias + ".fix_representation")
    val pointsValue = rs.getInt(tableAlias + ".points_value")
    val instrumentType = InstrumentType.fromString(rs.getString(tableAlias +".instrument_type"))
    val productType = ProductType.fromString(rs.getString(tableAlias + ".product_type"))

    Instrument(symbol, fixRepresentation, quoteCurrency, pointsValue, instrumentType, productType)
  }
}

object InstrumentType {
  def fromString(instrumentType: String): InstrumentType = Seq(CurrencyPair, Metal, CFD)
  .find(_.toString == instrumentType).get
}

object ProductType {

  def fromString(productType: String): ProductType = Seq(Commodity, Currency, Index)
  .find(_.toString == productType).get
}

The .get calls were hideous - using enumeration instead I can simply call the withName method on the enumeration as follows:

object DbInstrumentQueries {
  def instrumentExtractor(tableAlias: String = "s")(rs: ResultSet): Instrument = {
    val symbol = rs.getString(tableAlias + ".name")
    val quoteCurrency = rs.getString(tableAlias + ".quote_currency")
    val fixRepresentation = rs.getString(tableAlias + ".fix_representation")
    val pointsValue = rs.getInt(tableAlias + ".points_value")
    val instrumentType = InstrumentType.withNameString(rs.getString(tableAlias + ".instrument_type"))
    val productType = ProductType.withName(rs.getString(tableAlias + ".product_type"))

    Instrument(symbol, fixRepresentation, quoteCurrency, pointsValue, instrumentType, productType)
  }
}

So I think my preference going forward is to use Enumerations when the values are intended to be accessed from a repository and case objects/sealed traits otherwise.

grid is not a global, it is local to the main function. Change this:

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)

to this:

int nonrecursivecountcells(color grid[ROW_SIZE][COL_SIZE], int row, int column)

Basically you forgot to give that first param a name, grid will do since it matches your code.

I have added toArray() after pluck

$items = Item::get()->pluck('name', 'id')->toArray();

{{ Form::select('item_id', [null=>'Please Select'] + $items) }}

Your arguments are in the wrong order. Try git commit -m 'my notes' path/to/my/file.ext, or if you want to be more explicit, git commit -m 'my notes' -- path/to/my/file.ext.

Incidentally, git v1.5.2.1 is 4.5 years old. You may want to update to a newer version (1.7.8.3 is the current release).

You want to get the computed width. Try: .offsetWidth

(I.e: this.offsetWidth='50px' or var w=this.offsetWidth)

You'd treat one of the files as a python module and make the other one import it (just as you import standard python modules). The latter can then refer to objects (including classes and functions) defined in the imported module. The module can also run whatever initialization code it needs. See http://docs.python.org/tutorial/modules.html

In VBA we can not use if jj = 5 or 6 then we must use if jj = 5 or jj = 6 then

maybe this:

If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then
